[Problems to be Solved by the Invention]

However, in the technique of the aforementioned Patent Document 1, it is not possible to switch a plurality of seats from all directions at one time. That is, it is necessary to successively switch the seats, and it takes much time until the direction change of all the seats is completed, which may cause obstacles to the operation of the seat tool.

In addition, in each seat, not only the direction change of the electric power, but also the case that the passenger arbitrarily changes the direction manually. When the action is performed by the electric power, all the seats may not always be in the same direction. Therefore, it is usually necessary to individually change the direction of each seat after determining its direction. Therefore, the number of parts, such as a sensor and the like, which determines all directions in each seat is increased, and the control program becomes complicated, which causes a problem that the cost increases.

The present invention is directed to those who are problematic with the above-mentioned conventional technologies, and an object thereof is to provide a seat control device that can simplify the control of the state transition of a seat, and even a plurality of seats can be quickly switched all at once, With simple programs and parts, the switching operation can be easily controlled, which can reduce costs. [Means to solve the problem]

The essence of the present invention for achieving the aforementioned objects is an invention in which the following items exist. [1] A seat control device (100) is an operation control for switching the state of a seat (1), and includes a driving means (10) for driving a switching mechanism (10) that can switch the state of the seat (1) ( 42), and a control means (110) for controlling the operation of the driving means (42), the seat (1) can be moved to at least three predetermined states, that is, the first state by the switching mechanism (10) , And the second state and the third state transition, the first state to the second state, and the second state to the third state can be converted from both parties, respectively, and the first state to the third state can go through these The second state between the two states is switched. The aforementioned control means (110) is for the driving means (42) to switch the seat (1) to the first state, and first instructs to switch from the third state to the second state. , Then instructs the action to switch from the second to the first state, and to switch the seat (1) to the second state, instructs the action to switch from the first to the second state, and instructs to switch from the third to the first state. In the second state transition operation, when the seat (1) is switched to the third state, the first transition operation from the first state to the second state is instructed. Then instructs switching from the second operation toward the third state.

[2] In the seat control device (100) of [1], the seat (1) is provided with a detection means (18) for detecting a second state, and the control means (110) is the seat (1) When changing from the first or third state to the second state, the detection means (18) will not switch to the second state if it detects that the seat (1) is already in the second state action.

[3] In the seat control device (100) of [1] or [2], the driving means (42) is composed of a contact-stop motor (42), and is provided to prevent the The stopper (16, 17) for changing the state of the seat (1) to the other state by the rotation of the motor (42), and the control means (110) is an instruction to move the seat When the chair (1) is switched from any state to another state, the motor (42) is always rotated even when the seat (1) is under the predetermined conditions, but the stopper is moved by the stopper. (16, 17), preventing conversion of the seat (1) by rotation of the motor (42).

[4] In the seat control device (100) of [1], [2], or [3], the seat (1) has a plurality of seats, and each seat (1) includes the conversion mechanism (10) and The driving means (42) and the control means (110) are all converted at a time so that each seat (1) is aligned to any of the states. The driving means (42) for each seat (1) ), Always indicate the same action.

[5] For the seat control device (100) of the aforementioned [4], the plurality of seats (1) are grouped, and the grouped seat groups are added in sequence. The aforementioned control means (110) is from The upper seat groups are sequentially changed in each group in such a way that each seat (1) is aligned to any one state, and the driving means for each seat (1) in each group (42), always instruct the same action.

[6] For the seat control device (100) of the aforementioned [5], the plurality of seats (1) are arranged side by side in the front and rear, and the odd rows are assigned to the seats (1) and the even rows in order from the front row. 2 sets of seats (1).

[7] For the seat control device (100) of the aforementioned [1], [2], [3], [4], [5], or [6], the first state of the aforementioned seat (1) is for The front-back direction is a long state in the horizontal direction. The second state of the seat (1) is a forward cross state where the front-back direction is forward, and the third state of the seat (1) is a rear state in the front-back direction. Reverse cross state.

[8] In the seat control device (100) of [7], the switching mechanism (10) of the seat (1) includes a rotation mechanism (40) that rotatably supports the seat (1). And the sliding mechanism (14) that movably supports each of the seats (1) in the left-right direction of the rotation mechanism (40), and when the seat (1) is switched to the long state or the orthogonal cross state, An interlocking mechanism (50) that links the rotation of the seat (1) by the rotation mechanism (40) and the movement of the seat (1) by the sliding mechanism (14).

Next, the effect of the above-mentioned solution will be described. According to the seat control device (100) according to the aforementioned [1], the seat (1) can be shifted to at least three predetermined states by the switching mechanism (10), namely the first state, the second state, and the first state. 3 state transitions. The state of the seat (1) herein means various states including the direction and posture of the seat (1), and is not limited to a seat that is rotated by the entire horizontal rotation of the seat ( The direction 1) also includes the tilt angle and posture of the backrest or seat of the seat (1).

The first state to the second state of the seat (1) can be switched directly from both parties, and the second state to the third state of the seat (1) can also be switched directly from both parties. However, the first state to the third state of the seat (1) cannot be switched directly, but it is possible to switch from both sides by passing the second state between them. As described above, the second state of the seat (1) is a state in the middle of the transition process between the first state and the third state of the seat (1).

The switching mechanism (10) of the seat (1) is driven by the driving means (42), and the operation of the driving means (42) is controlled by the control means (110). Therefore, although the driving means (42) is electrically operated, the switching mechanism (10) does not necessarily need to be electrically driven by the driving means (42), and an operator (for example, a passenger) may be manually driven arbitrarily. In this case, the state of the seat (1) is not limited to a state controlled by the control means (110), and may be a state arbitrarily operated by an operator.

No matter how the control means (110) controls the action of the driving means (42), the seat (1) can be automatically switched to the first state, the second state, and the third state. In this control, the trouble of judging the state of the seat (1) before switching can be eliminated, and the flow of control for switching to each state is simplified as follows.

That is, when the seat (1) is switched to the first state, the control means (110) is a driving means (42) that first instructs the action to switch from the third state to the second state, and then instructs the second state to the first state. State transition actions. With this two-stage instruction, even if the seat (1) is in any of the first to third states, the seat (1) can always be switched to the first state.

When the seat (1) is switched to the second state, the control means (110) instructs the driving means (42) to switch from the first state to the second state, and instructs the driving means (42) to switch from the third state to the second state. Conversion action. Here, the two instructions have no time-related relationship. With the two instructions, even if the seat (1) is in any of the first or third states, the seat (1) can be uniformly moved toward the second. State transition.

When the seat (1) is switched to the third state, the control means (110) is a driving means (42) that first instructs the action to switch from the first state to the second state, and then instructs the second state to the third state Conversion action. With this two-stage instruction, even if the seat (1) is in any of the first to third states, the seat (1) can always be switched to the third state. Even if the seat (1) is in any of the states, the seat (1) can be switched to an arbitrary state with only the minimum instructions above.

According to the seat control device (100) of the aforementioned [2], among the three states of the seat (1), the second state having the highest probability of detecting presence (via) is provided with the seat (1) Detection method used (18). In addition, the control means (110) is a case where the seat (1) is switched from the first state or the third state to the second state. If the detection means (18) detects that the seat (1) is already In the second state, the operation of transitioning to the second state is not performed.

As a result, it is possible to save unnecessary driving of the driving means (42) having the highest frequency for switching the seat (1). The specific control is a command to suspend the transition to the second state, and the transition may not be performed. It is also possible to output a command to switch the operation to the second state, or to control the switched operation in accordance with another command regardless of the output.

According to the seat control device (100) according to the aforementioned [3], the control means (110) is an instruction to switch the seat (1) from any state to the other state, and the seat (1) is Under prescribed conditions, the motor (42) is always rotated. Accordingly, the control flow for selectively operating the motor (42) can be eliminated as much as possible, and the control can be simplified.

In addition, the prevention of the seat (1) conversion under the originally assumed condition does not need to go through a complicated control process, and can be mechanically prevented only by the stoppers (16, 17). Since the motor (42) can be stopped by contact, there is no need to worry about damage due to overload.

The control of the action of changing the state of the seat (1) above is as described in [4] above, and is not limited to one seat (1), and a plurality of seats (1) may be implemented as an object. When a plurality of seats (1) are targeted, the premise is that each seat (1) must be provided with the aforementioned conversion mechanism (10) and the aforementioned driving means (42). In addition, the control means (110) is a person who switches all at once so that each seat (1) is aligned to any of the states, and the driving means (42) of each seat (1) always instructs the aforementioned Same action.

According to this control, when the state of each seat (1) is changed, it is not necessary to judge the state before each change. That is, even if each seat (1) is in any of the states, the same command is always output by the driving means (42) toward each seat (1), and the same operation is performed all at once by the switching mechanism (10). , You can quickly switch to a specific state aligned.

In addition, as described in [5] above, a plurality of seats (1) may be grouped, and continuous control may be performed in each of the grouped seats. Here, each seat group is added in order. The aforementioned control means (110) is in order from the upper seat group, and each seat (1) is aligned in any one of the states in each group. Convert all at once. That is, the control means (110) is a driving means (42) for each seat (1) in each group, and all instruct the same operation.

The specific grouping is, for example, as described in [6] above, in the case where the plural seats (1) are arranged side by side in front and back, the odd numbered seats (1) and the even numbered seats are sequentially allocated from the front row. Two sets of chair (1) are preferred. Here, in the two sets of additional sequences, it does not matter if any one is in the upper position. When the state of each seat (1) is changed, the seats (1) adjacent to each other will not move at the same time. Since every other seat (1) moves forward and backward simultaneously, it is possible to prevent the seat (1) from interfering with each other.

And the state of the seat (1) is, for example, as described in [7] above, the first state is a long state in which the front-back direction becomes a horizontal direction, and the second state is a forward-cross state in which the front-back direction is forward. The third state is preferably a reverse cross state where the front-back direction is backward. Accordingly, the general seat (1) mounted on a railway vehicle can be directly applied.

Further, the switching mechanism (10) of the seat (1) is, for example, as described in [8], and includes a rotation mechanism (40) that rotatably supports the seat (1), and a seat (1) facing Each rotating mechanism (40) is supported by a sliding mechanism (14) that is movably supported in the left-right direction, and when the seat (1) is switched to the aforementioned long state or the aforementioned orthogonal crossing state, the seat ( An interlocking mechanism (50) that interlocks the rotation of the seat (1) and the movement of the seat (1) by the sliding mechanism (14) is preferred. According to this conversion mechanism (10), even if the seat (1) is arranged close to the wall surface, interference with the wall surface can be prevented during the operation of the seat (1). [Effect of the invention]

According to the seat control device of the present invention, the control of the state transition of the seat is simplified, and even a plurality of seats can be quickly switched all at once, and the switching operation can be easily controlled by simple programs and parts. Can reduce costs.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 to Fig. 33 show an embodiment of the present invention.的 The seat control device 100 of this embodiment is an operator who controls the state transition of the seat 1. As shown in FIG. 1, the seat control device 100 is a motor (driving means) 42 that drives the switching mechanism 10 that can switch the state of the seat 1, and a control means 110 that controls the operation of the motor 42.

First, the control target, that is, the seat 1 will be described.种类 Although the type of the seat 1 is not particularly limited, the following description is an example of a case where a two-seater seat is installed in a passenger compartment of a railway vehicle. As shown in FIG. 3, in the passenger compartment A of the railway vehicle, there is one row on each side in the front-back (progress) direction, and the plurality of seats 1 are arranged side by side forward and backward, and a passage is formed between the two rows. The seat 1 is for a two-seater, for example, and the two seat portions and the backrest are juxtaposed on both sides.

Each seat 1 is provided with a switching mechanism 10 that can change the state of the seat 1 to three predetermined states, that is, the first state, the second state, and the third state. The state of the seat 1 here means various states including the direction and posture of the seat 1 and is not limited to the direction of the seat 1 by the horizontal rotation of the entire seat 1. The reclining angle and posture of the backrest or seat of the seat 1 are also included, but in this embodiment, the "direction" of the seat 1 is taken as the state.

The directions of the state of the seat 1 by the switching mechanism 10 are respectively possible: the seat 1 is in a lateral direction with respect to the front-rear direction, and the seat back side is a first state parallel to the side wall A1 (hereinafter referred to as Long state); and seat 1 is a second state (hereinafter referred to as a normal cross state) that is forward to the front-rear direction and the seat back side is perpendicular to the side wall A1; and seat 1 is backward to the front-rear direction. The rear side of the seat is switched to a third state (hereinafter referred to as a reverse cross state) perpendicular to the side wall A1.

When the angle of the long state of the seat 1 is set to 0 °, the 90 ° rotation in one direction from the long state results in a normal cross state (90 °), and the 180 ° rotation in one direction further results in a reverse cross state (270 °). As described in detail later, the seat 1 may be rotated in the opposite direction. However, further rotation in one direction from the reverse cross state is restricted, and rotation in the opposite direction from the long state is also restricted.

The long state of the seat 1 to the forward cross state can be switched directly from both sides, and the normal cross state of the seat 1 to the reverse cross state can also be directly switched from both sides. However, the long state of the seat 1 to the reverse cross state cannot be switched directly, and it is necessary to switch from both sides by passing through the normal cross state between these. As described above, the forward cross state of the seat 1 is a state in the middle of the transition process between the long state and the reverse cross state of the seat 1.

As shown in FIG. 8, the conversion mechanism 10 is a part of the configuration of each seat 1 and includes a footrest 11, a mobile station 20, and a table frame 30 of the seat 1. The conversion mechanism 10 includes a rotation mechanism 40 that rotatably supports the seat 1, a slide mechanism 14 that movably supports each of the seats 1 in the left-right direction of the rotation mechanism 40, and a mechanism 1 An interlocking mechanism 50 that links the rotation of the seat 1 by the rotating mechanism 40 and the movement of the seat 1 by the sliding mechanism 14 when the long state or the normal crossing state is switched.

FIG. 9 shows the switching mechanism 10 in the long state, FIG. 10 shows the switching mechanism 10 in the forward crossing state, and FIG. 11 shows the switching mechanism 10 in the reverse crossing state. In the following, the cases where the forward crossing state and the reverse crossing state are collectively referred to are simply referred to as the crossing state. FIG. 12 shows a long state except the table frame 30 in the conversion mechanism 10, and FIG. 13 shows a cross state except the table frame 30 in the conversion mechanism 10.

As shown in FIGS. 12 and 13, the footrest 11 is fixed to the ground on the side of the wall surface A1 (refer to FIG. 8) in the passenger compartment of the vehicle. The foot stand 11 is formed in a frame shape that is long in a direction that intersects the side wall A1 substantially perpendicularly by a frame material. The upper surface portion 12 covering the upper side of the footrest 11 is substantially horizontal, and the long sides of the two sides extending in the longitudinal direction of the upper surface portion 12 are substantially perpendicular to the side wall A1, and the short sides of the front and back portions of the upper surface portion 12 are opposite the side wall A1 is arranged substantially in parallel.

The upper surface portion 12 is provided with an avoidance portion 12 a that allows a rotary shaft 41 that moves along with the advancement and retreat of the mobile stage 20 to be described later to pass along the movement trajectory thereof. The avoidance portion 12 a is a bay-shaped notch that is recessed toward the inside from the short side on the front side of the upper surface portion 12 toward the substantially center, and the short side on the front side opens. The avoidance portion 12 a is a portion for avoiding interference between the rotation shaft 41 and the upper surface portion 12. Related parts such as a stopper 16 for restricting the rotation direction of the table frame 30 are also attached to the upper surface portion 12.

The moving stage 20 is mounted on the lower side of the upper surface 12 of the footrest 11 so as to be able to advance and retreat in a direction (left-right direction) perpendicular to the side wall A1 through the slide mechanism 14. The slide mechanism 14 is provided with a pair of guide rails 15 and 15 provided inside the both side portions 13 and 13 of the foot stand 11. A pair of guide rails 15 and 15 face parallel to each other along the two long sides of the upper surface portion 12 of the foot stand 11, and both side portions 21 and 21 of the moving stage 20 described below are directly slidably fitted to The inside of each guide rail 15.

The mobile stage 20 is arranged on the lower side of the upper surface portion 12 of the footrest 11 and is formed into a rectangular frame group shape by a frame material. Both side portions 21 of the moving table 20 are slidably fitted inside the aforementioned guide rail 15. Therefore, the mobile station 20 can slide up and down while moving forward or backward in a direction substantially perpendicular to the side wall A1.

A mounting portion 22 of a rotation mechanism 40 (refer to FIG. 8) that rotatably supports the seat 1 is provided at substantially the center of the mobile table 20. The rotating frame 40 mounted on the mounting portion 22 allows the stage frame 30 to be rotatably supported on the mobile stage 20. The rotation mechanism 40 is, for example, a unit that is rotatably combined with a pair of ring-shaped rotary disks, which are not shown in the figure, and a bearing is provided therebetween. The rotation mechanism 40 is such that a lower rotary disk is fixed around a circular hole in the mounting portion 22, and an upper rotary disk is fixed on a bottom surface side of the table frame 30.

The conversion mechanism 10 first includes a motor 42 as a driving means for driving the rotation mechanism 40. The motor 42 is omitted from the figure, and is equipped with a speed reducer for contacting the stopper. For example, the motor 42 is provided with a torque motor that is resistant to an output torque of a predetermined value or more applied when the contact is stopped. The sprocket that rotates integrally with the output shaft is pivotally supported on the output shaft of the motor 42. The teeth on the outer periphery of the sprocket are partially projected above the upper surface portion 12 by the avoidance portion 12 a of the foot stand 11.

The rotation axis 41 of the rotation mechanism 40 serving as the rotation center of the seat 1 is the center line of the upper and lower rotating disks. Although it is not a physical person with physical status in this embodiment, The side extends upward and passes through the avoiding portion 12 a without interfering with the upper surface portion 12. In the upper rotating disk that becomes the periphery of the rotating shaft 41, as described above, the table frame 30 is integrally mounted, and the seat 1 and the table frame 30 rotate around the rotating shaft 41 as a center.

As shown in FIGS. 9 to 11, the table frame 30 is arranged on the upper side of the upper surface portion 12 of the leg table 11 and is formed of a rectangular metal plate. The table frame 30 is a supporter to which the seat 1 is mounted, and has a rectangular shape in both sides that is aligned with the bottom surface of the seat portion of the seat 1. In such a table frame 30, illustration is omitted, and a plurality of perforations for meshing the teeth of the sprocket are provided along the circumference around the rotation axis 41 as a center.

Therefore, when the sprocket is rotated by the motor 42, the plurality of perforations arranged on the circumference of the table frame 30 centered on the rotation shaft 41 are sequentially rotated and moved. Therefore, the seat 1 is configured to be rotated by the power of the motor 42. . To explain in detail, the transition from the long state of the seat 1 to the forward cross state and the transition from the forward cross state to the reverse cross state are performed by the forward rotation of the motor 42. On the other hand, the transition from the reverse cross state to the forward cross state of the seat 1 and the transition from the forward cross state to the long state are performed by the reverse rotation of the motor 42.

However, as shown in FIG. 1, the center passageway of the passenger compartment A of the railway vehicle is located side by side, and the right seat 1 and the left seat 1 are symmetrical to each other. Therefore, although the right-row seat 1 and the left-row seat 1 are rotated and slid symmetrically, the rotation direction of the motor 42 may be reversed according to this, or the rotation direction of the motor 42 may be unified.

As shown in FIG. 20, a stopper 16 is provided on the table frame 30 to prevent the transition from the reverse cross state of the seat 1 to the forward cross state by the normal rotation of the motor 42. This stopper 16 is a member for restricting the seat 1 from rotating 270 ° or more by engaging with an engaged portion (not shown) provided on the bottom surface side of the seat 1.

As shown in FIG. 14, a stopper 17 is provided on the table frame 30 to prevent the transition from the long state of the seat 1 to the cross state by the reverse rotation of the motor 42. This stopper 17 is a member for restricting the seat 1 from rotating to 0 ° or less by engaging with an engaged portion (not shown) provided on the bottom surface side of the seat 1.

The switching mechanism 10 is provided with an interlocking mechanism 50 that links the rotation and advancement and retraction of the seat 1 so that the seat 1 does not interfere with the side wall A1 when the direction of the seat 1 is changed to a long state or a cross state. When the interlocking mechanism 50 rotates the seat 1 and the table frame 30 together, the rotation of the table frame 30 is converted into a linear motion and transmitted to the mobile station 20 through the rotation mechanism 40, and the mobile station 20 and the table frame 30 are aligned with the side wall. A1 advances or retreats in the direction of vertical crossing close or isolated.

As shown in FIGS. 9 and 10, the interlocking mechanism 50 includes a guide rail 51 provided on the upper side of the upper surface portion 12 of the foot stand 11 and a roller 52 provided on the lower side of the table frame 30. The roller 52 is provided with an auxiliary roller 53. The guide rail 51 is formed on the upper surface portion 12 of the footrest 11 and is formed in a long shape that is bent and extended in both directions by the side of the mounting portion 22, and protrudes upward from a horizontal reference surface of the upper surface portion 12 by a predetermined height.

The roller 52 is rotatably supported on the lower side of the table frame 30 so as to protrude downward from a position eccentric from the rotation shaft 41 of the seat 1. As shown in FIG. 22, in the rotation shaft 52a of the roller 52, the base end of the arm 54 is pivotally supported, and in the front end of the arm 54, the auxiliary roller 53 is rotatable and rotates around the rotation axis 52a. It is pivotally supported around the axis. The auxiliary roller 53 is movable along the guide groove 55 formed in a circular arc shape with the rotation axis 52a as the center in the table frame 30. The auxiliary roller 53 is supported close to or isolated from the roller 52 and passes through the spring. The member 56 is often pushed in the approaching direction.

The rollers 52 and the auxiliary rollers 53 hold the guide rails 51 from both sides when the seat 1 is switched to a long state or a cross state. In this state, the roller 52 and the auxiliary roller 53 are moved from one end of the guide rail 51 to the other end along with the rotation of the seat 1. The rotation of the table frame 30 is converted into linear motion and transmitted through the rotation mechanism 40. Go to mobile station 20. Thereby, the seat 1 can be configured to change from the long state in FIG. 9 to the normal cross state in FIG. 10, or conversely, from the long cross state to the long state.

Further, the switching mechanism 10 is provided with a rotation lock mechanism 60 that restricts the table frame 30 (seat 1) to each of the rotation positions in the long state and the cross state in a non-rotatable manner. Here, since the rotation lock mechanism 60 is restrained in a non-rotatable manner with respect to the footrest 11, the mobile stage 20 is also necessarily restrained in such a way that the footrest 11 cannot move forward and backward.

As shown in FIGS. 9 to 11, the rotation lock mechanism 60 is provided with a lock pin 61 that can be moved up and down across the table frame 30 from the foot table 11 side, and is provided on the table frame 30 to lock the lock pin 61. Locking holes 62a, 62b, 62c. The locking holes 62a, 62b, and 62c are respectively formed in the rectangular table frame 30 along one long side of the seat back side and two short sides of both sides of the seat 1. Set a total of three. Each of the locking holes 62a, 62b, and 62c is located slightly away from the end edge of each side of the table frame 30, and is not provided with a cutout that is partially open, but is provided with a surrounding cover to avoid stress concentration and increase strength. Surrounded by holes.

The lock pin 61 is an assembly unit 60 a which is attached to the lower side of the upper surface portion 12 of the foot stand 11. The upper surface portion 12 is formed with a hole through which the locking pin 61 is inserted, and the locking pin 61 is capable of coming out from the upper surface portion 12 of the foot stand 11. The lock pin 61 is inserted into the locking holes 62a, 62b, and 62c which are engaged with the vertically aligned table frame 30 side at this position when the seat 1 is switched to the long state or the cross state.

In detail, in the long state shown in FIG. 9, the lock pin 61 is inserted into the locking hole 62 a engaged with one long side of the table frame 30. Further, in the normal crossing state shown in FIG. 10, the lock pin 61 is inserted into the locking hole 62 b that is engaged with one short side of the table frame 30. Further, in the reverse crossing state shown in FIG. 11, the lock pin 61 is inserted into the locking hole 62 c engaged with the other short side of the table frame 30. In addition, in a position where the lock pin 61 protrudes downward from the upper surface portion 12, it does not interfere with a part of the mobile station 20 which moves forward and backward on the lower side of the upper surface portion 12.

The locking pin 61 is operated by electric operation and manual operation. The locking pin 61 protrudes upward and is inserted into the locking position of the locking holes 62a, 62b, and 62c. The release position of. The stroke from the locked position to the released position of the lock pin 61 is different between electric operation and manual operation. To explain in detail, as shown in FIG. 23, the lock pin 61 is assembled into the unit 60 a through a drive mechanism including a link 63 having one end as a rotation center 63 a to move in and out.

Here, the electric-side cable 64 and the manual-side cable 65 for driving the link 63 are respectively connected to different portions of the rotation radius of the link 63. When the operation amounts of the respective cables 64 and 65 are the same, the stroke of the cable approaching the rotation center 63 a of the link 63 becomes larger. Using this difference in rotation radius, the stroke of the lock pin 61 performed by the manual-side cable 65 is set to half of the stroke performed by the electric-side cable 64.

The manual-side cable 65 has a manual operation lever (not shown) connected to its tip, and the manual operation lever 65 also has a function of adjusting the stroke. Therefore, the electric-side cable 64 and the manual-side cable 65 can be oppositely mounted, and the stroke diameter of the lock pin 61 by the operation of the manual-side cable 65 can be shortened even if the difference in rotation radius is not used.

On the other hand, as shown in FIGS. 9 and 24 (a), the locking holes 62a, 62b, and 62c for locking the locking pin 61 are used to lock (restrict) the seat 1 in a long state. On the lower side of the stopper hole 62a, a metal plate 32 having a hole corresponding to the stopper hole 62a is attached. Therefore, the locking hole 62a is set so that the stroke of the locking pin 61 is not increased to a thickness greater than that of the other locking holes 62b and 62c (refer to FIG. 24 (b)). The lock is released.

Importantly, when the seat 1 is in the long state, the lock of the rotation lock mechanism 60 cannot be released by the operation performed by the manual-side cable 65, but can be released by the operation performed by the electric-side cable 64. The operations performed by electric are performed by the cabin crew and station members of the vehicle, and the operations performed manually are mainly performed by passengers.

In addition, the emergency manual operation sections connected to the rotation lock mechanism 60 and the forward / backward lock mechanism 70 are respectively provided on the feet of the other footrest 11 and can be unlocked in the event of a power failure or the like. The stroke amount of the locking pins 61 and 71 by the operation of the emergency manual operation portion is larger than the thickness of the respective metal plate 32 and the hinge 75, and therefore it changes from the long state to the cross state or from A transition from a cross state to a long state is possible.

According to such a rotation lock mechanism 60, the lock pin 61 emerges from the footrest 11 fixed to the vehicle. Therefore, if the table frame 30 is locked in a non-rotatable manner, the table frame 30 can also be locked in a forward and backward direction through the mobile table 20 supported by the rotation mechanism 40. This type of seat 1 is non-rotatable and cannot be locked while advancing and retreating. The lock pin 61 is not attached to the mobile table 20 but is mounted on the footrest 11, and the upper surface 12 of the footrest 11 is opened to avoid and rotate. The interference avoiding portion 12 a of the mechanism 40 is realized.

Further, the switching mechanism 10 is provided with an advancing and retreating lock mechanism 70 for restraining the table frame 30 (seat 1) at various positions in a long state and an intersecting state so as not to advance or retreat. The forward / backward lock mechanism 70 is different from the above-mentioned rotation lock mechanism 60 and is a person who restrains the mobile table 20 from moving forward and backward with respect to the foot table 11. According to such a forward / backward lock mechanism 70, even if the state of restraint by the rotation lock mechanism 60 is released, the seat 1 can be restrained only by being unable to move forward and backward.

As shown in FIG. 25, the forward and backward lock mechanism 70 includes a lock pin 71 that can be moved up and down across the mobile table 20 from the foot table 11 side, and a locking hole provided in the mobile table 20 to lock the lock pin 71. 72a, 72b. Each of the locking holes 72a and 72b is provided at the front and rear ends of the frame member 23 on the lower side of the rear of the mobile station 20 and extending in the front-rear direction, as shown in FIG. Each of the locking holes 72 a and 72 b is provided at the front and rear ends of the frame material 23, and is not provided with a cutout that is partially opened, but is provided with a hole surrounded to avoid stress concentration and increase strength.

The lock pin 71 is an assembly unit 70 a which is disposed inside the foot stand 11 located on the lower side of the mobile station 20. The locking pin 71 is swung upward from the lower side of the frame material 23 of the mobile table 20, and when the seat 1 is switched to a long state or a cross state, the locking pin 72 is inserted and engaged in each of the locking holes 72a aligned at the same position. , 72b. The lock pin 71 is attached to the footrest 11 side in the same manner as the lock pin 61 described above, but its attachment position is different.

In detail, in the long state shown in FIG. 15, the lock pin 71 is inserted into the locking hole 72 a (see FIG. 25) engaged with the front side. However, the lock pin 71 in the long state does not necessarily need to be inserted into the locking hole 72a. Furthermore, in the normal crossing state shown in FIG. 18, the lock pin 71 is inserted into the locking hole 72b engaged in the rear side (refer to FIG. 25). Similarly, in the reverse crossing state shown in FIG. 21, the lock pin 71 is also inserted into the locking hole 72b engaged with the rear side.

As shown in FIG. 27, the lock pin 71 is often pushed in a lock position that projects upward by the spring member 73. Such a lock pin 71 is displaced only to a release position which is sunk downward by resisting the urging force of the spring member 73 only by electric operation. The lower end of the lock pin 71 is connected to an electromagnetic coil (not shown) through a link 74, and the lock pin 71 is pulled downward and displaced toward the release position by driving of the electromagnetic coil. Therefore, the lock pin 71 is different from the case of the lock pin 61 of the rotation lock mechanism 60 described above, and can only be operated by electric operation, and the lock cannot be released during manual operation.

According to the forward / backward lock mechanism 70, although the rotation lock mechanism 60 is locked, there is no need to operate, but when the rotation lock mechanism 60 is unlocked, each of the table frames 30 (seat 1) cannot be moved forward and backward. The mobile station 20 is locked. That is, when the seat 1 cannot be rotated, the seat 1 cannot be moved forward and backward, but when the seat 1 is rotated, the seat 1 cannot be moved forward or backward only, or the seat 1 can be moved forward and backward with the rotation of the seat 1.

When the seat 1 is rotated 90 ° from the long state (0˚) to the cross state (90˚) in the forward / backward locking mechanism 70, the leading end of the lock pin 71 is from the frame material 23 shown in FIG. 16 The front end side (right side in the figure) passes relatively above the locking hole 72b until the rear end side (left side in the figure) moves relatively, and returns slightly toward the front end side, and then inserts the locking hole 72b again (refer to FIG. 19) . Here, when the lock pin 71 is moved toward the rear end side, it is necessary to make it impossible to enter the locking hole 72 b by the urging force of the spring member 73.

Therefore, as shown in FIG. 25, the hinge 75 for temporarily plugging the locking hole 72b is provided upside down in front of the locking hole 72b. The hinge 75 is pushed in front of the locking hole 72b, and is usually standing up. As shown in FIG. 26, when the tip of the lock pin 71 moved relatively from the front comes into contact with the hinge 75, the hinge 75 falls down in a state where the locking hole 72b is blocked against the urging force. The hinge 75 does not fall in the opposite direction.

Conversely, when the front end of the lock pin 71 moves relatively forward from the rear end side to the front end side of the frame member 23, it is necessary for the lock pin 71 to enter the locking hole 72b without catching the standing hinge 75. Therefore, as shown in FIG. 27, a side pin 76 is provided on the side of the lock pin 71 to resist the urging force of the spring member 73 and is maintained in a state where the lock pin 71 is retracted.

The side pin 76 is a side perpendicularly intersecting with the axial direction of the lock pin 71, and is detachably supported by the lock pin 71. In the outer periphery of the lock pin 71, the locking holes 71a, 71b are recessed at positions separated from each other vertically. As shown in FIG. 28, when the leading end of the side pin 76 is engaged with the locking hole 71a on the upper side of the lock pin 71, the lock pin 71 is held in the retracted release position, as shown in FIG. The hinge 75 is moved. When the leading end of the side pin 76 is engaged with the locking hole 71 b on the lower side of the lock pin 71, the lock pin 71 is held in a protruding lock position.

As shown in FIGS. 30 and 31, the side pin 76 is movably supported in the axial direction through the swing member 77, so that the tip end can be engaged with and disengaged from the locking holes 71a and 71b of the lock pin 71. status. The tip of the swing member 77 is halfway through the side pin 76 that can be pushed and pulled. The tip and the base end on the opposite side of the swing center are detachably disposed with respect to the release lever 78 fixed to the mobile station 20 side. Therefore, when the release lever 78 is engaged and pressed toward the base end of the swing member 77, the side pin 76 is disengaged from the lock pin 71 as the tip of the swing member 77 swings, and the lock pin 71 by the side pin 76 is released. Restraint of was lifted.

Next, the seat control device 100 which is the basis of the present invention will be described. As shown in FIG. 1, the seat control device 100 includes the motor (driving means) 42 that drives the switching mechanism 10 that can switch the state of the seat 1, and a sensor that detects that the seat 1 is in a cross state. A control device (detection means) 18, an operation switch 101 for performing various operations, and a control panel (control means) 110 for controlling the operation of the motor 42 described above.

The control panel 110 is a function for collectively monitoring and controlling the operation of the motor 42 and the transmission and reception of signals from the sensor 18, etc., to achieve the "control means" of the invention. The control panel 110 is a sequencer including an input / output circuit, a communication circuit, and the like as main components in addition to the CPU and main memory, that is, ROM and RAM, which perform various data processing.

The control panel 110 is usually provided in a driver's seat or the like and collectively controls the conversion of the plurality of seats 1 in the passenger compartment A. In FIGS. 2 to 6, it is shown that each seat 1 in the passenger compartment A of a vehicle is controlled by the control panel 110, but all the seats 1 in the passenger compartment A of the entire vehicle are controlled by a single control panel 110. Yes.

The motor 42 and the sensor 18 of each seat 1 are connected to the control panel 110 via an adapter (not shown) provided in each seat 1. In fact, the seats R1 to R4 in the right row and the seats L1 to L4 in the left row shown in FIG. 2 may be separately connected to the control panel 110 through each adapter. The motor 42 is a stopper that can be contacted as described above, and is, for example, a torque motor.

The sensor 18 is not shown in the figure, and is mounted on the upper surface portion 12 of the foot stand 11. It is equivalent to “on” when the table frame 30 (seat 1) is in a cross state, and outputs a detection signal. Means ". Such a sensor 43 is constituted by, for example, a proximity switch, a magnetic sensor, or the like that operates in accordance with a distance from a part of the stage frame 30, and is connected to the control panel 110 through the adapter.

In addition, the operation switch 101 is usually installed in the driver's seat and the like as the control panel 110, and is provided with an instruction to switch each seat 1 to a long state and an instruction to switch each seat 1 to a cross state. And a button for inputting an instruction to switch each seat 1 to the reverse cross state. The operation switch 101 is connected to the control panel 110 through a signal line.

As shown in FIG. 2, the function of the control panel 110 is achieved, and the transition of each seat 1 is programmed as follows. a. The control panel 110 is a case where the seat 1 is switched to a long state. According to an instruction from the operation switch 101, the motor 42 of each seat 1 first instructs the operation of switching from the reverse cross state to the forward cross state (motor 42). 180˚), and then instructs the operation to switch from the normal crossing state to the long state (the reverse rotation of the motor 42 is 90˚).

b. The control panel 110 is a case where the seat 1 is switched to the cross state, and the operation of switching from the long state to the cross state is instructed to the motor 42 of each seat 1 according to the instruction from the operation switch 101 (the motor 42 90 ° forward rotation), and an operation to switch from the reverse crossover state to the forward crossover state is instructed (reverse rotation of the motor 42 is 180 °). There is no time-related relationship between the two action commands here, and either one can be output first.

c. The control panel 110 is a case where the seat 1 is switched to the reverse cross state. According to the instruction from the operation switch 101, the motor 42 of each seat 1 first instructs the action of switching from the long state to the cross state (motor 42). Forward rotation of 90 °), and then instruct the operation to switch from the forward crossing state to the reverse crossing state (forward rotation of the motor 42 is 180 °).

In addition, the command to switch the seat 1 from the long state to the forward cross state and the command to switch from the forward cross state to the reverse cross state are common to the operation instruction signal of the forward rotation of the motor 42 and the rotation angle of the motor 42 (actuation Time) is different. In addition, the command to switch each seat 1 from the reverse cross state to the forward cross state and the command to switch from the forward cross state to the long state are common to the operation instruction signal for the reverse rotation of the motor 42 and the rotation angle of the motor 42 ( (Action time) is different.

In addition, the control panel 110 is a case where each seat 1 is switched from a long state or a reverse cross state to a normal cross state. If it is detected by the sensor 18 that the seat 1 is already in a cross state, it is not performed at this point. The action of transition to the forward crossing state. This control is performed by suspending the transition to the normal cross state (forward rotation of the motor 42 by 90 ° or reverse rotation of 180 °), and the operation may be performed without performing the transition. Alternatively, although an instruction to switch the operation to the forward crossing state is output, regardless of the output, the operation may be controlled to be suspended based on another instruction.

In addition, the control panel 110 is an operation for instructing each seat 1 to switch from any state to another state, and the motor 1 is always rotated even when the seat 1 is under a predetermined condition. However, even when the motor 42 rotates under the predetermined conditions, the stoppers 16 and 17 prevent the switching of the seat 1 by the rotation of the motor 42.

Under the predetermined conditions, it is an instruction to switch the seat 1 from the long state to the forward cross state, and to switch the seat 1 to the reverse cross state when the seat 1 is in the reverse cross state. the meaning of. In this case, although the control panel 110 uniformly rotates the motor 42 in a forward direction, the stopper 16 prevents the forward rotation of the seat 1 from being reversed by the forward rotation of the motor 42. .

Similarly, when instructing the operation of changing the seat 1 from the reverse cross state to the forward cross state and the action of changing the cross state from the forward cross state to the long state, the case where the seat 1 is in the long state is also equivalent to the aforementioned predetermined Under the conditions, the control panel 110 rotates the motor 42 uniformly in the reverse direction, but the stopper 17 prevents the reverse rotation of the motor 42 from changing from the long state of the seat 1 to the cross state.

Further, according to the control panel 110, each seat 1 can be grouped, and the grouped seat groups are added in order. The control panel 110 shifts all the seats 1 at a time from the upper group in order, aligning each seat 1 of each group to one of them, and the same applies to the motor 42 of each seat 1 of each group. The same operation is instructed (control of a to c). In the present embodiment, in the passenger compartment A of the railway vehicle shown in FIG. 3, two sets of seats 1 in an odd-numbered row and seats 1 in an even-numbered row are sequentially assigned from the front.

Next, the operation of the conversion mechanism 10 according to this embodiment will be described in detail. As shown in FIG. 8, in the conversion mechanism 10, the mobile unit 20 is arranged on the lower side with the upper surface portion 12 of the footrest 11 as the middle, and the stage supported by the mobile unit 20 by the rotation mechanism 40 is arranged on the upper side. Box 30. Therefore, the switching mechanism 10 has a structure that overlaps the footrest 11, the mobile station 20, the upper surface portion 12 of the footrest 11, and the table frame 30 in order from the bottom.

With this structure, the upper surface portion 12 located between the mobile station 20 and the table frame 30 hinders the movement of the rotation shaft 41 when the mobile station 20 advances and retreats, but the rotation shaft 41 passes through the upper surface portion 12 The avoidance portion 12 a does not interfere with the upper surface portion 12. Thereby, advancing and retreating of the mobile station 20 in the lower side of the upper surface portion 12 of the footrest 11 can be achieved.

As shown in FIG. 33, when the seat 1 is rotated together with the table frame 30, the rotation of the table frame 30 is converted into a linear motion and transmitted to the mobile table 20 through the rotation mechanism 40. Therefore, the moving stage 20 advances and retreats with the rotating stage frame 30 in a direction perpendicular to the side wall A1 (see FIG. 8). Through the interlocking of the rotation and advancement of the seat 1, even if the seat 1 is close to the side wall A1, it can be easily moved in a series of actions without interference with the side wall A1: the seat back side and the side wall A1 become parallel and long The state (Fig. 33 (a)) and the state where the seat back side perpendicularly crosses the side wall A1 (Fig. 33 (c)) change the direction of the seat 1.

As shown in FIGS. 9 and 14, when the table frame 30 of the seat 1 is in a long state (0 (), the lock pin 61 of the rotation lock mechanism 60 is inserted and engaged on one long side of the table frame 30.的 锁孔 62a。 The locking hole 62a. Here, since the lock pin 61 comes out from the footrest 11 fixed on the ground, not only the seat 1 cannot be rotated, and it cannot be locked at the same time as it cannot move forward and backward. At this time, in the forward-backward locking mechanism 70, it is not particularly necessary to lock, and the lock pin 71 is in a free and non-fixed state.

As shown in Figs. 33 (a) to 33 (c), when the table frame 30 (seat 1) is changed from the long state (0˚) to the cross state (90˚), only the motor 42 Motorized operation with forward rotation. When the lock pin 61 of the rotation lock mechanism 60 is released from the locking hole 62a, there is only an excess stroke of the thickness of the metal plate 32 shown in FIG. 24 (a), and this large stroke can be operated only by electric power. Therefore, when the seat 1 is in the long state (0˚), the lock of the rotation lock mechanism 60 cannot be released by manual operation.

In FIG. 33 (a), after the lock of the rotation lock mechanism 60 is released by electric operation, as shown in FIG. 33 (b), the table frame 30 (seat 1) is oriented in one direction (in FIG. 33, it is straight Hour hand) When rotating, the table frame 30 is converted into linear motion by the interlocking mechanism 50. That is, when the table frame 30 is rotated without interfering with the side wall A1 (refer to FIG. 8), the table frame 30 is rotated forward while moving forward toward the passage side, and then retracted toward the side wall A1 while being rotated backward by 90 °.

As shown in FIGS. 14 and 17, in the interlocking mechanism 50, the rollers 52 and the auxiliary rollers 53 on the table frame 30 side hold the guide rails 51 on the foot table 11 from both sides. In this state, the roller 52 and the auxiliary roller 53 move from one end of the guide rail 51 to the other end along with the rotation of the table frame 30, and the rotation of the table frame 30 is converted into linear motion. Here, the rollers 52 rotate and move along one side of the guide rail 51, and the auxiliary rollers 53 are also eccentrically rotated while being pushed along the other side of the guide rail 51. Therefore, the rollers 52 and 53 do not rotate. Disengaged from the guide rail 51.

As shown in FIG. 33 (c), if the table frame 30 (seat 1) has reached the cross state (90˚), the lock pin 61 of the rotation lock mechanism 60 is inserted into and engaged with the table frame 30. The side locking hole 62b (refer to FIG. 17) locks the table frame 30 in a non-rotatable manner. At the same time, the lock pin 71 of the forward / backward lock mechanism 70 moves until it can be inserted into the locking hole 72b (refer to FIG. 19) on the rear side of the moving stage 20.

Here, when the leading end of the lock pin 71 advances and retreats with the rotation of the stage frame 30 along with the rotation of the stage frame 30, the front end of the frame member 23 shown in FIG. 16 passes through the locking hole 72b once. At this time, if the tip of the lock pin 71 is in contact with the hinge 75 in front of the locking hole 72b from the front side, the hinge 75 will fall down as shown in FIG. 26, and the locking hole 72b will be temporarily blocked. Thereafter, the leading end of the lock pin 71 is slightly restored toward the front end side of the frame member 23, and is moved again to a position where the locking hole 72b can be inserted.

Next, when the table frame 30 (seat 1) is switched from the forward cross state (90˚) shown in FIG. 10 to the reverse cross state (270˚) shown in FIG. 11, the forward direction of the motor 42 is used. The rotation is performed by electric operation or manual operation. In order to release the lock pin 61 of the rotation lock mechanism 60 from the locking hole 62b, it is sufficient to reduce the stroke without the metal plate 32 shown in FIG. 24. Therefore, the lock of the rotation lock mechanism 60 can be released not only by electric operation but also by manual operation.

In the normal cross state (90 °) shown in FIG. 17, after the lock by the rotation lock mechanism 60 is released, the seat back side of the seat 1 (not shown) is directed toward the passage side in one direction (at the first Figure 17 is a clockwise rotation of 180˚. At this time, the advancing and retreating lock mechanism 70 is locked, and the table frame 30 does not advance and retreat in the front-rear direction. Further, in the interlocking mechanism 50, the roller 52 and the auxiliary roller 53 on the table frame 30 side are detached from the other end of the guide rail 51 on the foot 11 side to the outside.

However, when seat 1 is in the cross state (90˚), the seat 1 is rotated in the opposite direction (counterclockwise in FIG. 17) from the manual operation back to the long state (0˚). Figure reference) the possibility of interference. Therefore, in the cross state (90 °), it is necessary to restrict the seat 1 from rotating in the other direction. Therefore, as shown in FIG. 32, only a metal plate 33 (equivalent to the metal plate 32) having a predetermined thickness is attached along the sheet-side half portion which is the other side of the peripheral edge of the locking hole 62b. Therefore, in the manual operation, the transition from the forward crossing state (90˚) to the long state (0˚) cannot be performed.

The seat 1 is rotated 180˚ in one direction, and as shown in FIG. 20, when the reverse cross state (270˚) is reached, the lock pin 61 of the rotation lock mechanism 60 is inserted into the short side of the other side of the table frame 30 The side locking hole 62c locks the table frame 30 in a non-rotatable manner. At this time, the forward / backward lock mechanism 70 is locked. In addition, the manual operation also performs the same operation for the seat 1 which is already in the reverse cross state (270 °) in the case of electric operation. However, the seat 1 is operated by the stopper 16 in the footrest 11, It does not rotate further from the reverse cross state (270 °) in the same direction.

Next, when the table frame 30 (seat 1) is returned from the reverse cross state (270˚) to the forward cross state (90˚), the electric operation or manual operation is performed by the reverse rotation of the motor 42 Come on. After the lock by the rotation lock mechanism 60 is released, in FIG. 20, the table frame 30 is rotated 180 ° in the opposite direction (counterclockwise in FIG. 20) this time. At this time, the advancing and retreating lock mechanism 70 is locked, and the table frame 30 does not advance and retreat in the front-rear direction.

The seat 1 is rotated 180˚ in the opposite direction, and as shown in FIG. 17, when the front cross state (90˚) is reached, the lock pin 61 of the rotation lock mechanism 60 is inserted into the short side of the frame 30 The side locking hole 62b locks the table frame 30 in a non-rotatable manner. At this time, the forward / backward lock mechanism 70 is locked.

Further, in the interlocking mechanism 50, the roller 52 and the auxiliary roller 53 on the table frame 30 side are engaged again from the other end of the guide rail 51 on the foot table 11 side. At this time, the auxiliary roller 53 moves toward the spring member 56 from the range of the guide groove 55 by the pushing of the spring member 56 (refer to FIG. 22), so that the other end of the guide rail 51 can be reliably blocked . In addition, by manual operation, for the seat 1 which is already in the cross state (90 °), the sensor 18 is turned on, so that the turning operation by the electric operation is not controlled.

Next, as shown in FIG. 33 (c) to FIG. 33 (a), when the seat 1 is returned from the normal cross state (90˚) to the original long state (0˚), only the motor 42 is used. The electric operation is performed by reverse rotation. As described above, the lock pin 61 of the rotation lock mechanism 60 cannot pass through the thickness of the metal plate 33 (refer to FIG. 32) in the sheet-side half of the locking hole 62 b in a small stroke by manual operation.

In FIG. 33 (c), after the lock of the rotation lock mechanism 60 is unlocked by electric operation, the table frame 30 (seat 1) is rotated in the other direction (counterclockwise in the figure), and it is also linked. The mechanism 50 is converted to rotate in a linear motion. That is, during the rotation of the table frame 30 without interfering with the side wall A1 (refer to FIG. 8), the table frame 30 is rotated forward toward the side of the passage side while rotating, and then retracted toward the side wall A1 side and rotated back 90˚. .

At this time, in the interlocking mechanism 50, the roller 52 and the auxiliary roller 53 on the table frame 30 side are moved across the other end from the other end of the guide rail 51 on the foot 11 side, and the rotation of the table frame 30 is converted into a straight line. motion. In the forward / backward lock mechanism 70, the lock by the lock pin 71 is released. To explain in detail, as shown in FIG. 29, the front end of the side pin 76 is engaged with the locking hole 71a on the upper side of the lock pin 71, so that the lock pin 71 is held in a retracted released state.

As shown in FIG. 33 (a), when the table frame 30 (seat 1) reaches the long state (0˚), the lock pin 61 of the rotation lock mechanism 60 is inserted and engaged on one long side of the table frame 30 The locking hole 62a (refer to FIG. 14) locks the table frame 30 in a non-rotatable manner. Moreover, in the forward-backward lock mechanism 70, the side pin 76 is detached from the lock pin 71, and is in a free and non-fixed state.

To explain in detail, in FIG. 16, when the lock pin 71 moves to the front of the locking hole 72 a on the front side of the frame member 23, as shown in FIG. 31, the release lever 78 on the mobile stage 20 side is used. The swing member 77 is pushed and swung, and the side pin 76 is disengaged from the locking hole 71 a of the lock pin 71. In addition, as shown in FIG. 14, when the table frame 30 (seat 1) is in the long state (0˚), the table frame 30 does not change from the long state (0˚) by the stopper 17 in the foot stand 11. Rotate in the opposite direction (counterclockwise in the figure).

In this way, according to the conversion mechanism 10, the table frame 30 is arranged on the upper side of the upper surface portion 12 of the foot 11 which is the fundamental fixed side, and the mobile station 20 is rotated without being positioned between the upper surface portion 12 and the upper surface portion 12. Therefore, it becomes possible to restrain the table frame 30 from the leg 11 side easily. When the table frame 30 is locked from the side of the leg table 11, it is not only that the table frame 30 cannot be rotated, and the table frame 30 cannot advance and retreat to the leg table 11 at the same time.

Therefore, it is possible to realize a rotation lock mechanism 60 that restricts the table frame 30 while being non-rotatable and cannot move forward and backward. According to such a rotation lock mechanism 60, not only the restriction of the table frame 30 to the rotation of the mobile table 20, but also the restriction of the movement of the mobile table 20 to the advancement and retreat of the foot table 11 can be performed by a single locking mechanism.

Also, unlike the rotation lock mechanism 60 described above, with the advancement and retraction lock mechanism 70 that can restrain the table frame 30 from advancing and retreating, only the restraint seat 1 cannot advance and retreat even when the restraint state by the rotation lock mechanism 60 is released. , The seat 1 can be rotated in a state where the forward and backward position of the seat 1 is fixed.

Next, the details of the control performed by the seat control device 100 of the present embodiment will be described. As shown in FIGS. 3 to 7, in the passenger compartment A of the railway vehicle, for example, there are one row on each side in the front-rear direction, and the four seats 1 are arranged side by side in the front-rear direction. Here, each seat 1 is in the right and left rows, and is divided into two groups of odd and even rows as described above. Hereinafter, as illustrated in the figure, the seat 1 in the right column is sequentially distinguished into a seat R1, a seat R2, a seat R3, and a seat R4, and the seat 1 in the left row is sequentially distinguished from the front. These are seats L1, L2, L3, and L4.

According to the seat control device 100, for example, at the starting station or the terminal station of a railway vehicle, all the seats 1 in the passenger compartment A of each vehicle can be automatically switched in either direction. However, if the states of all the seats 1 are switched at the same time, since the seats 1 adjacent to each other may interfere with each other, they are sequentially switched to each of the odd-numbered columns and the even-numbered columns that are side by side. In addition, when the seats 1 adjacent to each other do not interfere with each other, it is a matter of course that the states of all the seats 1 may be switched all at once. Hereinafter, the state transition of each seat 1 will be explained by case.

[A. Case of Transition to Forward Crossing State] (1) When the seats 1 are switched to the forward crossing state, control is started from the original state of each seat 1, that is, the long state or the reverse crossing state. However, in the reverse cross state, it is possible to switch to the forward cross state by manual operation, so some of the seats 1 may already be in the forward cross state.

[A1. Transition from Long State to Forward Crossing State] Hereinafter, the transition from the long state to the forward crossing state will be described with reference to FIG. 3. As shown in FIG. 3 (a), when each seat 1 is in a long state, when the vehicle starts from the starting station, etc., each seat 1 is switched to a state of being in a cross state toward the terminal station. By operating the operation switch 101, an instruction to switch each seat 1 to the cross state is sent to the control panel 110.

The control panel 110 is based on an instruction from the operation switch 101. In FIG. 3 (a), first, the motors 42 of the odd-numbered seats R1, R3, L1, and L3 are instructed to switch from the long state to the cross state. . In this case, as shown in FIG. 3 (b), the motors 42 of the seats R1, R3, L1, and L3 in the odd-numbered rows are all rotated forward at one time (in the case of the left columns L1 and L3, they are rotated in reverse), In this step, all of the seats R1, R3, L1, and L3 in the odd-numbered rows are all shifted to the normal cross state at a time.

Next, the control panel 110 instructs the motors 42 of the seats R1, R3, L1, and L3 in the odd-numbered rows to switch from the reverse cross state to the forward cross state in FIG. 3 (b). However, the seats R1, R3, L1, and L3 of these odd-numbered rows have been converted into a positive cross state in the foregoing step, because this state is detected by the sensor 18, so in this step, the positive The action of cross state transition is not performed.

Thereafter, in FIG. 3 (c), the control panel 110 instructs the motors 42 of the even-numbered seats R2, R4, L2, and L4 to switch from the long state to the cross state. In this case, as shown in FIG. 3 (d), the motors 42 of the even-numbered seats R2, R4, L2, and L4 are all rotated forward at a time (in the case of the left columns L2 and L4, they are rotated in the reverse direction). In this step, the seats R2, R4, L2, and L4 in the even-numbered rows are all shifted to the normal cross state at a time.

Next, the control panel 110 instructs the motors 42 of the even-numbered seats R2, R4, L2, and L4 to switch from the reverse cross state to the forward cross state in FIG. 3 (d). However, these even-numbered seats R2, R4, L2, and L4 have been converted into a positive cross state in the foregoing step, because this state is detected by the sensor 18, so in this step The transition to the forward crossing state is not performed.以上 Through the above-mentioned continuous control, as shown in FIG. 3 (e), all the seats 1 in the guest room A can be switched from the long state to the orthogonal cross state all at once.

[A2. Case of Transition from Reverse Crossing State to Forward Crossing State] Hereinafter, a case of transition from the reverse crossing state to the forward crossing state will be described with reference to FIG. 4. When the vehicle arrives at the starting station and reverses its direction, when the vehicle switches from the reverse crossing state of the starting station direction to the positive crossing state of the terminal station as shown in Figure 4 (a), the operation switch 101 is operated to make Each seat 1 is instructed to switch to the cross state toward the control panel 110. In addition, before the switching control, it is possible that the seats R2 and L2 which have already entered the cross state by the manual operation of the passenger.

The control panel 110 is based on the instruction from the operation switch 101. In FIG. 4 (a), first, the motors 42 of the odd-numbered seats R1, R3, L1, and L3 are instructed to switch from the long state to the cross state . At this time, the odd-numbered rows of seats R1, R3, L1, and L3 are in a reverse cross state, and the control panel 110 rotates the motors 42 of the odd-numbered rows of seats R1, R3, L1, and L3 in this state. However, each seat 1 is prevented from switching from the reverse cross state to the forward cross state by the forward rotation of the irrelevant motor 42 by the stopper 16 described above. Here, since the motor 42 can be stopped by contact, there is no need to worry about damage due to overload.

Next, in FIG. 4 (b), the control panel 110 instructs the motors 42 of the seats R1, R3, L1, and L3 in the odd-numbered rows to switch from the reverse cross state to the forward cross state. In this case, the motors 42 of the seats R1, R3, L1, and L3 in the odd-numbered rows are all reversely rotated at one time (the left rows are rotated in the case of L2 and L4). With this step, as shown in FIG. 4 (c) As shown, the odd-numbered rows of seats R1, R3, L1, and L3 are all shifted to a normal cross state at a time.

Thereafter, in FIG. 4 (c), the control panel 110 instructs the motors 42 of the even-numbered seats R2, R4, L2, and L4 to switch from the long state to the cross state. At this time, although the last seats (the right end in the figure) of the seats R4 and L4 are in the reverse cross state, the control panel 110 rotates the motors 42 of the seats R4 and L4 in this state. However, the seats R4 and L4 are prevented from being switched to the cross state by the stoppers 16, but they are the same as the case of the odd-numbered rows in FIG. 4 (a).

In FIG. 4 (c), the seats R2 and L2 in the second row from the front side (left in the figure) are already in a cross state by manual operation by the passenger. Therefore, regarding these seats R2 and L2, the forward crossing state is detected by the sensor 18, so the operation of switching to the forward crossing state again in this step is not performed. In FIG. 4, although the state of the seats 1 in the right and left rows of the guest room A are shown in the same front and rear positions, respectively, the seat 1 in the left and right rows is of course the same. The status is different also possible.

Next, in FIG. 4 (d), the control panel 110 instructs the motors 42 of the even-numbered seats R2, R4, L2, and L4 to switch from the reverse cross state to the forward cross state. In this case, the motors 42 of the seats R4 and L4 at the end (right end in the figure) that have not yet entered the reverse cross state are all reversely rotated at one time (forward rotation in the case of the left column L4). As shown in Fig. (E), the seats R4 and L4 are switched toward the cross state.

At this time, since the seats R2 and L2 in the second row from the front side (left in the figure) are detected by the sensor 18 as being in a cross state, they will be described with reference to FIG. 4 (c). The same is true for the seats R2 and L2, and the action of being switched again to the cross state is not performed.以上 Through the above-mentioned continuous control, as shown in FIG. 4 (e), all the seats 1 in the guest room A can be switched from the reverse cross state to the forward cross state all at once.

[B. Case of transition to reverse cross state] (1) When each seat 1 is switched to reverse cross state, the original state of each seat 1 is controlled from the long state or the cross state. However, in the forward cross state, it is possible to switch to the reverse cross state by manual operation, so some of the seats 1 may already be in the reverse cross state.

[B1. Case of transition from long state to reverse cross state] Hereinafter, a case of transition from the long state to the reverse cross state will be described with reference to FIG. 5. As shown in FIG. 5 (a), when each seat 1 is in a long state, when the vehicle arrives at the terminal station, etc., and each seat 1 is switched to the reverse cross state toward the starting station, the operation switch 101 is operated to make the Each seat 1 is instructed to switch to the reverse cross state to the control panel 110.

The control panel 110 is based on an instruction from the operation switch 101. In FIG. 5 (a), first, the motors 42 of the odd-numbered seats R1, R3, L1, and L3 are instructed to switch from the long state to the cross state. . In this case, the motors 42 of the seats R1, R3, L1, and L3 in the odd-numbered rows are all rotated forward at one time (in the case of the left columns L1 and L3, they are rotated in reverse). With this step, as shown in FIG. 5 (b) As shown, the odd-numbered rows of seats R1, R3, L1, and L3 are all shifted to a normal cross state at a time.

Next, in FIG. 5 (b), the control panel 110 instructs the motors 42 of the seats R1, R3, L1, and L3 in the odd-numbered rows to switch from the forward cross state to the reverse cross state. In this case, the motors 42 of the seats R1, R3, L1, and L3 in the odd-numbered rows are all rotated forward at one time (in the case of the left columns L1 and L3, they are rotated in reverse). With this step, as shown in FIG. 5 (c) As shown, the odd-numbered rows of seats R1, R3, L1, and L3 are all switched to the reverse cross state all at once.

Thereafter, in FIG. 5 (c), the control panel 110 instructs the motors 42 of the even-numbered seats R2, R4, L2, and L4 to switch from the long state to the cross state. In this case, the motors 42 of these even-numbered seats R2, R4, L2, and L4 are all rotated forward at one time (reverse rotation in the case of L2 and L4 on the left), and by this step, as shown in FIG. 5 (d) As shown, the seats R2, R4, L2, and L4 in the even-numbered rows are all shifted toward the cross state all at once.

Next, the control panel 110 instructs the motors 42 of the even-numbered seats R2, R4, L2, and L4 to switch from the forward cross state to the reverse cross state in FIG. 5 (d). In this case, the motors 42 of the even-numbered seats R2, R4, L2, and L4 are all rotated forward at one time (reverse rotation in the case of the left columns L2 and L4). As shown, the even-numbered seats R2, R4, L2, and L4 are all switched to the reverse cross state at a time.以上 With the above-mentioned continuous control, as shown in FIG. 5 (e), all the seats 1 in the guest room A can be switched from the long state to the reverse cross state all at once.

[B2. Case of Transition from Forward Crossing State to Reverse Crossing State] Hereinafter, a case of transition from the forward crossing state to the reverse crossing state will be described with reference to FIG. 6. When the vehicle arrives at the terminal and reverses its direction, the switch from the normal cross state in the direction of the terminal to the reverse cross state in the direction of the starting station as shown in Figure 6 (a) is operated. An instruction to switch each seat 1 to the reverse cross state is sent to the control panel 110. Before the changeover control, it is possible that the seats R2 and L2 which have already entered the reverse cross state by manual operation of the passenger.

The control panel 110 is based on the instruction from the operation switch 101. In FIG. 6 (a), first, the motors 42 of the odd-numbered seats R1, R3, L1, and L3 are instructed to switch from the long state to the cross state. . However, the seats R1, R3, L1, and L3 of these odd-numbered rows are originally in a cross state, so the state is detected by the sensor 18, and the operation is changed to the cross state in this step. Not carried out.

Next, in FIG. 6 (b), the control panel 110 instructs the motors 42 of the odd-numbered seats R1, R3, L1, and L3 to switch from the forward cross state to the reverse cross state. In this case, the motors 42 of the seats R1, R3, L1, and L3 in the odd-numbered rows are all rotated forward at one time (in the case of the left columns L1 and L3, they are rotated in reverse). With this step, as shown in FIG. 6 (c) As shown, the odd-numbered rows of seats R1, R3, L1, and L3 are all switched to the reverse cross state all at once.

Thereafter, in FIG. 6 (c), the control panel 110 instructs the motors 42 of the even-numbered seats R2, R4, L2, and L4 to switch from the long state to the cross state. At this time, the seats R2 and L2 in the second row of the previous (left in the figure) are in the reverse cross state, and the control panel 110 also rotates the motors 42 of the seats R2 and L2 in this state. However, for the seats R2 and L2, the stopper 16 prevents the forward rotation of the irrelevant motor 42 from being changed from the reverse cross state to the forward cross state. Here, the motor 42 can be stopped by contact, as described above.

And in FIG. 6 (c), the seats R4 and L4 at the end of the even-numbered columns (the right end in the figure) are originally in a state of being in a cross state. Therefore, regarding these seats R4 and L4, because the forward cross state is detected by the sensor 18, the operation of switching to the forward cross state again in this step is not performed. In FIG. 6, the right and left rows of the guest room A show the same examples of the seats 1 in the same front and rear positions, but of course the left and right seats 1 The status is different also possible.

Next, the control panel 110 instructs the motors 42 of the even-numbered seats R2, R4, L2, and L4 in FIG. 6 (d) to switch from the forward cross state to the reverse cross state. In this case, the motors 42 of the seats R4 and L4 on the rear side (right end in the figure) that have not yet crossed the state are all forwardly rotated at one time (reverse rotation in the case of the left column L4). As shown in FIG. 6 (e), the last seats R4 and L4 are also switched to a cross state.

At this time, the seats R2 and L2 in the second row of the previous (left in the figure) are in the reverse cross state, and the control panel 110 also rotates the motors 42 of the seats R2 and L2 in this state. However, the seats R2 and L2 are prevented from shifting to the cross state by the stoppers 16 as described above.以上 With the above-mentioned continuous control, as shown in FIG. 6 (e), all the seats 1 in the guest room A can be switched from the forward cross state to the reverse cross state all at once.

[C. Case in which the seat is switched to the long state] In the case where each seat 1 is switched to the long state, the original state of each seat 1 is controlled from the case of a normal cross state or a reverse cross state. Hereinafter, a case where each seat 1 is switched from any one of the states to the long state will be described with reference to FIG. 7.

As shown in FIG. 7 (a), in a situation where each seat 1 is in a cross state or a reverse cross state, each seat 1 is switched to a long state by a situation such as the passage in the passenger room A is widened. , The operation switch 101 is operated, so that the instruction to switch each seat 1 to the long state is sent to the control panel 110.

The control panel 110 is based on an instruction from the operation switch 101. In FIG. 7 (a), the motors 42 of the seats R1, R3, L1, and L3 in the odd-numbered rows are first instructed to switch from the reverse cross state to the forward cross state action. The odd-numbered rows of seats R1, R3, L1, and L3 are all reversely crossed, so the motors 42 of these odd-numbered rows of seats R1, R3, L1, and L3 are all reversely rotated at one time (the left columns L1 and L3 In this case, forward rotation), as shown in FIG. 7 (b), the seats R1, R3, L1, and L3 in the odd-numbered rows are all shifted to the normal cross state at a time.

Next, in FIG. 7 (b), the control panel 110 instructs the motors 42 of the seats R1, R3, L1, and L3 in the odd-numbered rows to switch from the forward crossing state to the long state. In this case, the motors 42 of the seats R1, R3, L1, and L3 in these odd-numbered rows are all reversely rotated at one time (forward rotation in the case of L1 and L3 on the left), and by this step, as shown in FIG. 7 (c) As shown, the odd-numbered rows of seats R1, R3, L1, and L3 are all shifted to a long state all at once.

Thereafter, in FIG. 7 (c), the control panel 110 instructs the motors 42 of the even-numbered seats R2, R4, L2, and L4 to switch from the reverse cross state to the forward cross state. In this case, in the seats R4 and L4 at the end of the reverse cross state (the right end in the figure), the motor 42 is rotated in the reverse direction (in the case of the left column L4), by this step, as shown in FIG. 7 ( As shown in d), the seats R2 and L4 are switched toward the cross state.

At this time, in FIG. 7 (c), the seats R2 and L2 in the second row from the previous (left in the figure) are originally in a cross state. Therefore, regarding these seats R2 and L2, the forward crossing state is detected by the sensor 18, and the operation of switching to the forward crossing state again in this step is not performed. In addition, in FIG. 7, the right and left rows of the guest room A show the same example of the seats 1 in the same front and rear positions, but of course the left and right seats 1 The status is different also possible.

Next, in FIG. 7 (d), the control panel 110 instructs the motors 42 of the even-numbered seats R2, R4, L2, and L4 to switch from the forward crossing state to the long state. In this case, the motors 42 of the even-numbered seats R2, R4, L2, and L4 are all reversely rotated at one time (forward rotation in the case of the left columns L2 and L4), and by this step, as shown in FIG. 7 (e) As shown, the even-numbered seats R2, R4, L2, and L4 are all switched to the long state all at once.这种 With such continuous control, as shown in FIG. 7 (e), all the seats 1 in the passenger room A can be switched all at once in a long state.

As described above, according to the control of the seat control device 100, even if each seat 1 is in any of the long state, the forward cross state, and the reverse cross state by electric or manual operation, there is no need for the seat. The chair 1 discriminates each state individually, and as shown in FIG. 2, the operation of the motor 42 is controlled only by a minimum uniform operation instruction signal, and the seat 1 can be switched to an expected state. Therefore, it does not take time to switch between the states of the seat 1, and the plurality of seats 1 can be switched all at once in a short time, and the operation control switched by a simple program and parts can also be easily realized.

In particular, the seat control device 100 has only one of the three states of the seat 1 and has a sensor 18 for the seat 1 for detecting the presence or absence of the right-crossing state. . In addition, the control panel 110 changes the seat 1 from the long state or the reverse cross state to the normal cross state. If the sensor 18 detects that the seat 1 is already in the normal cross state, the sensor 18 does not switch to the normal cross state. Actions. Therefore, only one sensor 18 is provided in the conversion of the seat 1, and redundant driving of the motor 42 having the highest frequency can be saved.

In addition, when the seat control device 100 instructs the operation to switch the seat 1 from any state to the other state, the motor 42 will always be rotated if the seat 1 is under the aforementioned predetermined conditions. Accordingly, the control flow for selectively operating the motor 42 can be eliminated as much as possible, and the control can be simplified. Further, the blocking of the change of the seat 1 under a predetermined condition that was not originally assumed does not need to go through a complicated control flow, and can be mechanically prevented only by the stoppers 16 and 17. Here, since the motor 42 can be stopped by contact, there is no need to worry about damage due to overload.

In addition, in the seat control device 100 of the present embodiment, two groups of the seats 1 in the odd-numbered rows and the seats 1 in the even-numbered rows are grouped to control the time shift. Therefore, since the seats 1 adjacent to each other in the front and back do not move at the same time with each other, every other seat 1 in the front and the back is moved simultaneously. Therefore, the overall operation time can be shortened as much as possible, and the seats 1 can be prevented from Motion interference.

Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and changes and additions without departing from the scope of the present invention are also included in the present invention. For example, the specific shapes of the foot stand 11, the mobile stand 20, and the stand frame 30 are not limited to those illustrated.

In the foregoing embodiment, the example in which the seat 1 is a two-seater seat has been described. However, the three-seat and one-seat seat 1 may be used. In addition, the seats 1 in the passenger room A are aligned to be all the same. For example, the seats 1 juxtaposed on the right row are for two-seater, and the seats 1 juxtaposed on the left row are for 3-seater. Yes.

And in the foregoing embodiments. Although the three states of the seat 1 are described as examples of transitioning to the long state, the normal cross state, and the reverse cross state, the state of the seat 1 is not limited to the horizontal direction, and other examples include the backrest of the seat 1 Or the tilt angle and posture of the seat may be determined. Furthermore, in the foregoing embodiment, each seat is grouped into two groups of odd and even columns. For example, the definition of a group is not particularly limited, and grouping by vehicle units is also considered.

The avoidance portion 12 a provided on the upper surface portion 12 of the leg platform 11 is a bay-shaped notch that extends from a short side on the front side of the upper surface portion 12 to a substantially central depression, but only at the movement locus along the rotation axis 41. It suffices that the upper surface portion 12 does not interfere with the rotation axis 41. Therefore, the avoidance portion may be, for example, an elongated hole and a groove provided in the upper surface portion 12 including the movement trajectory of the rotation shaft 41.

Furthermore, the interlocking mechanism 50 is not limited to those having a guide rail 51. That is, the interlocking mechanism may be constituted by a cam provided on the lower side of the table frame 30 and a roller-shaped cam follower provided on the upper surface portion 12 of the foot stand 11. In such a cam-type interlocking mechanism, by rotating the cam while abutting with the cam follower, and converting this rotational force toward the linear movement of the moving table 20, the seat 1 can be crossed from the long state to the front The state changes from the forward crossing state to the long state. [Industrial availability]

The present invention relates to a seat control for a seat for a theater, home, or office chair in addition to a seat for a vehicle provided in a passenger compartment of a railway vehicle, an airplane, an automobile, a ship, or the like. The devices can be widely used.
