Description

  The present invention relates to a chair for a game hall that can automatically be stored in a posture tilted forward toward a game stand when a seat integrated with a backrest is not in use.

In an amusement hall, chairs are lined up toward a large number of game tables arranged side by side, seated back to back, and the passages between them are generally narrow. Therefore, a device has been developed in which the seat is automatically moved forward and stored when not in use. (For example, refer to Patent Document 1).
This playground chair is attached to the upper end of the leg by a spring biased so that it can automatically move forward, but when sitting, it must enter a narrow space with the game table. In addition, there was a problem that it was difficult to leave even when leaving.

Therefore, the inventors have been able to perform a chair for a game hall that can be performed from the side without going to the front of the game table when sitting and leaving, and that is automatically stored on the game table side when leaving the seat. It was developed (see Patent Document 2).
In the chair of Patent Document 2, a seat integrated with a backrest provided with a rotation shaft, a seat support provided with a vertical cylindrical bearing supporting the rotation shaft, and a lower end of a front leg and a rear leg are connected to a base. , And a leg that can be tilted in the front-rear direction by connecting each upper end to a seat support. Then, a spring for urging the leg forward tilted, and a return means provided with a rotating cam at the lower end of the pivot shaft, and engaged with the stroke cam in conjunction with the forward tilt of the leg to pivot the seat. It has.
The player can pull the chair in the retracted state, rotate it 90 degrees, and sit down from the side. When leaving the seat, turn the chair 90 degrees while sitting on the back. You can just sit and leave smoothly. Moreover, when the user leaves the seat, it is automatically returned to the retracted state without any operation.

Japanese Utility Model Publication No. 6-13595 Japanese Patent Application No. 2009-236084

  The chair for a game hall of Patent Document 2 is considerably effective and attracts attention in a game hall with a narrow passage. However, it was pointed out that this chair made a loud noise when the leg was tilted and it was desired to improve it. In addition, there are indications that the backrest and the seat are integrated, and they are not elastic when seated on the backrest, so they are tired when sitting for a long time, and are not suitable for use by women. In addition, when adjusting or exchanging the game table, there are problems that it is difficult to work if the chair is in the retracted position, or that it takes time to install the chair in the game hall.

  Therefore, the present invention eliminates the above-mentioned drawbacks and makes it easier to handle a chair for a game hall in which the seat is rotatable and the legs tilt in the front-rear direction, and is automatically stored on the game stand side when leaving the seat. It aims to provide an improved version.

  In order to solve the above-described object, the gaming chair according to the present invention is configured as follows. That is, a seat integral with a backrest having a pivot shaft at the center of the bottom, a seat support provided with a vertical cylindrical bearing for pivotally supporting the pivot shaft, a base attached to the floor, and the seat A leg that can be tilted in the front-rear direction with the upper end connected to the support and the lower end connected to the base, and when leaving the seat, the leg automatically tilts forward and rotates so that the seat faces the game stand. A gaming chair provided with storage means that is moved and stored, wherein the leg comprises a fixed-length front leg and a compression-enhanced rear leg, the storage means comprising: It is characterized by comprising a tilting return means using a tension spring or a torsion coil spring and a turning return means provided by engaging with the turning shaft.

  Here, the terms “front leg”, “forward”, and “forward tilt” are used with the direction toward the game table as the front. The seat is configured to be pivotable by fitting a pivot shaft provided at the center of the bottom thereof to a vertical cylindrical bearing provided on the seat support. The range of rotation of the seat is preferably about 90 degrees to the left and right. This is because if it is more than that, the rotation return means becomes complicated.

The leg is composed of a fixed-length front leg and a rear leg that can be expanded and contracted with a compression spring. Each upper end is connected to a seat support and the lower end is connected to a base so as to be tiltable in the front-rear direction.
The rear leg is contracted by a compression spring when seated and when seated against the backrest.
A stopper for preventing further tilting is provided at the forward tilted storage position and at the position where the seat is leaned back to the maximum while leaning against the backrest. The stopper may be provided as appropriate, and is not particularly limited. However, it is easy to lock the upper end or lower end of the front leg or the rear leg to the seat support or the base at a predetermined angle. In addition, what is necessary is just to make the range (angle) in which a leg tilts appropriate. Furthermore, the shape of the front leg and the rear leg is arbitrary, such as a cylindrical shape or a U-shaped cross section, and is not particularly limited.

  As described in claim 2, the leg may be provided with a position (semi-stop position) that stops when the leg is tilted backward with the same force in the middle of the backward tilting process when the leg is tilted from the retracted position. . Furthermore, when tilting backward, it is sufficient to lean on the backrest. The semi-stop position is provided with means for locking the front leg to the rear leg when the leg tilts backward to a predetermined position.

  The tilting return means of the retracting means is generally constructed such that one end of the tension spring is connected to the base and the other end is connected to the rear leg, but it is connected to the base at the lower end of the front leg or the rear leg. You may arrange | position a torsion coil spring so that it may incline forward.

  In the case of a tension spring, if a spring having a large urging force is used to quickly return the tilt, a strong noise is generated by strongly contacting the stopper when the tilt is returned. In order to prevent this, as described in claim 5, it is preferable to provide a buffering means for suppressing the tilting speed composed of the cam and the coil spring at the connecting portion with the base at the lower end of the front leg or the rear leg.

  In addition, in the case of adjusting or exchanging the game table, a person on the store side often works in front of the game table. However, in this case, the chair is in the retracted position. As described, when the leg is tilted backward from the retracted position to a predetermined position, a forward tilt lock device is provided on the base for locking the lock pin from being tilted forward by the operation of the foot lever. Good.

  As for the rotation return means, it is simple to attach a torsion coil spring to the rotation shaft (Claim 3). However, as described in Claim 4, a rotation cam is provided at the lower end of the rotation shaft, and the front leg is attached. A stroke cam having a cam surface that engages with the rotating cam in conjunction with the forward tilt and rotates the rotation shaft so that the seat faces the game table may be provided. The shape of the rotary cam and the stroke cam and the means for engaging are not particularly limited. Further, the torsion coil spring of claim 3 may be supplementarily added to the rotation return means of claim 4 and used.

  As described in claim 7, the gaming chair is fixed to a bracket that is detachably attached to the bottom surface of the seat, and the base is installed on the floor via the mounting base. It is desirable that the seat support and the base are assembled to the leg and the bracket is assembled to the seat support to form a leg unit.

  The gaming chair according to the present invention is fitted to a vertical cylindrical bearing provided on a seat support with a pivot shaft at the bottom center of the seat, and the upper end is connected to the seat support and the lower end is connected to the base. It is equipped with a pivotable leg consisting of a front leg and a rear leg, and when leaving the seat, the leg automatically tilts forward and the storage means that the seat faces the game table side. Pull the chair forward and rotate it 90 degrees to sit down from the side, and when leaving the seat, sit on the backrest and rotate it 90 degrees away from the side to sit and separate smoothly. You can sit and do not need to do anything when you leave. In addition, the leg consists of a fixed-length front leg and a rear leg that can be expanded and contracted with a compression spring, so that a moderate reaction force is urged when leaning against the backrest, making it difficult to get tired even if sitting for a long time It became a thing.

  In addition, as shown in claim 2, if the leg has a semi-stop position where the front leg is locked to the rear leg in the middle of the backward tilting position when the leg is finally tilted from the retracted posture, the leg can lean against the backrest. It is easy for a person who sits on the front side and plays a game (it seems to be common among women).

  According to a fifth aspect of the present invention, the tilt return means uses a tension spring, and the buffer means for suppressing the tilt speed composed of the cam and the coil spring at the connecting portion with the base at the lower end of the front leg or the rear leg. If the tension spring is provided, it can be quietly stored even if the tension spring is strengthened.

  According to a sixth aspect of the present invention, there is provided a forward tilt lock device in which when the leg is tilted backward from the retracted position to a predetermined position, the lock pin is locked to the rear leg by the operation of the foot lever to lock the forward tilt. If the base is provided, the chair can be easily locked to the position tilted backward from the stowed position when the game table is adjusted or exchanged.

  Further, as described in claim 4, if the rotation return means is provided with a rotation cam at the lower end of the rotation shaft and a stroke cam that is engaged with the front leg in conjunction with the forward tilt, When taking a seat, the chair can be rotated with a light operating force.

  Furthermore, as described in claim 7, if the entire chair is divided into three parts, a seat, a leg unit, and a mounting base, and can be connected with bolts, the state of storage and transportation can be made compact, and the game It can be carried into the site in a short time.

FIG. 4 is a perspective view showing a state in which the chair is divided for transportation, in which (a) is a seat integrated with the backrest, (b) is a leg unit, and (c) is a mounting base.

An embodiment of a game chair according to the present invention will be described with reference to the drawings.
FIG. 1 is a side view showing a posture when the chair of the present invention is stored.
In this chair, a seat 1 integrated with a backrest 2 is rotatably attached to a seat support 4, and the seat support 4 is attached to a leg 3 that can be tilted in the front-rear direction on a base 5 fixed on the floor. Installed.
When the player leaves the seat, storage means is provided in which the seat 1 faces forward (in the direction of the game table) and the leg 3 is inclined forward to a predetermined position.

  First, the seat 1 is formed integrally with the backrest 2, and a bracket 11 having a rotation shaft 12 fixed at the center can be attached to the back surface of the seat receiver 1a with a bolt. The rotating shaft 12 is rotatably fitted to a vertical cylindrical bearing 13 fixed to the seat support 4 (see FIGS. 2 to 4). Here, the range in which the seat 1 can be rotated is limited to 90 degrees on both the left and right sides, and a stopper that abuts against the seat support 4 when the 90 degree is rotated is provided on the seat 1 (not shown). .

The rotation shaft 12 is provided with a seat rotation return means by a torsion coil spring 15.
This is because the torsion coil spring 15 is externally fitted to the rotating shaft 12 and both ends thereof are fixed to the front and rear of the bracket 11 and fixed to the upper portion of the seat support 4. The locking pin 16a is locked. The torsion coil spring 15 is arranged to be urged so that the seat 1 always rotates forward.

Further, in this embodiment, in addition to the torsion coil spring 15 described above, a rotation cam 12a and a stroke cam 14 are used as the rotation return means of the seat 1.
In this apparatus, as shown in FIG. 4, a rotary cam 12 a is fixed to the lower end of the rotary shaft 12, and the stroke cam 14 that engages with the leg 3 as the leg 3 tilts forward is located around the lower portion of the vertical cylindrical bearing 13. Is fixed to the front leg 3A.
The rotary cam 12a has a rod shape with a substantially elliptical cross section, the cam surface 14a of the stroke cam 14 is a substantially V-shaped groove, and the back portion 14b has a certain width and a certain length.

As the leg 3 tilts forward, the rotating cam 12a rotates so that the seat 1 faces forward by engaging with the cam surface 14a of the stroke cam 14. When the rotary cam 12a is engaged with the back portion 14b, the seat 1 is tilted forward while being directed forward, and is in the retracted posture. In the retracted posture, the seat 1 cannot be rotated.
Further, when the seat 2 is retracted from the retracted posture and pulled backward to sit down, the seat 1 does not rotate until a certain point (while the rotary cam 12a is engaged with the back portion 14b). Tilt back to straight.

The leg 3 is composed of a fixed-length front leg 3A and a rear leg 3B which is internally provided with a compression spring and can be expanded and contracted. Each upper end is connected to the seat support 4 by connecting pins 7a and 7b, and the lower end is connected to the base 5 by connecting pins 7c and 7d, and can be tilted in the front-rear direction.
When the front leg 3A is tilted forward by a predetermined angle, a locking portion 3D (see FIG. 8) that contacts the seat support 4 is formed, and the lower end is tilted backward by a predetermined angle. A locking portion 3 </ b> C for locking to the base 5 is formed.

As shown in FIGS. 1, 2, and 5, the rear leg 3 </ b> B has a support member in which a guide member 21 is fixedly provided at a substantially central portion of an outer frame 20 having a U-shaped cross section, and a compression spring 23 is externally fitted thereto. A rod 22 is fitted. The compression spring 23 has an upper end locked to the locking member 22 b and a lower end locked to the upper end of the guide member 21. A locking member 22c is fixed to the lower end side of the support bar 22, and is locked to the lower end of the guide member 21 when the leg 3 is retracted forward.
A bracket 22a to which the connecting pin 7b is connected is fixed to the upper end of the support bar 22. A locking member 24 is fixed to the outer frame 20 below the support bar 22 so that the lower end of the support bar 22 abuts when the rear leg 3B has the minimum length.

  The tilting return means for returning the leg 3 to the retracted position where the leg 3 is tilted forward when leaving the seat is by the tension spring 6, the lower end is locked to the connecting pin 7c at the lower end of the front leg 3A, and the upper end is the middle of the rear leg 3B. The position is locked. Thereby, the leg 3 is always urged forward.

The connecting pin 7d attached to the lower end of the rear leg 3B is provided with a buffer means 30 that operates during storage. As shown in FIGS. 5 and 6, a sliding cam 32 urged by a coil spring 35 is engaged with a rotating cam 33 fixed to the locking member 24 of the outer frame 20. .
The rotating cam 33 is fixed to an attachment member 34 fixed to the lower end of the locking member 24, and the sliding cam 32 has a sliding piece 32 a formed integrally with the base 5. It is provided so as to be slidably engaged with the concave receiving base 31.
The cam surfaces of the rotating cam 33 and the sliding cam 32 are formed so as to push in the sliding cam 32 as the rotating cam 33 rotates counterclockwise. When the sliding cam 32 is pushed in, the sliding piece 32a integral therewith is guided and moved in the cradle 31, and the coil spring 35 is gradually compressed.

  Further, as shown in FIG. 7, a forward tilt lock device 40 for locking to the rear leg 3B to lock the tilt return is provided approximately in the middle between the connection pin 7c and the connection pin 7d on the side surface of the base 5. It has been. In this apparatus, as shown in FIG. 8, a lock pin 46 is provided on a bracket 45 fixed to a base 5 so as to be movable in the left-right direction of the chair. 41 is connected. One end of the lock pin 46 is connected to the foot lever 41 by a pin 43, and a spring 44 is sheathed on the lock pin 46, and one end thereof is locked to the lock pin 46 and the other end is locked to the bracket 45. Yes.

As shown in FIG. 9A, the relationship between the lock pin 46 and the rear leg 3B is such that the path of the lock pin 46 is blocked by the rear leg 3B and the foot lever 41 is depressed when the chair is in the retracted position. I can't.
When a hand is placed on the chair backrest 2 from the retracted posture and moved backward, a space is created at the lower end of the rear leg 3B, as shown in FIG. 9B. Then, by stepping on the foot lever 41, the lock pin 46 can be advanced into the space. If the hand is released from the backrest 2 in this state, the leg 3 is tilted forward by the tension spring 6, but the lower end of the rear leg 3B comes into contact with the lock pin 46 and stops as shown in FIG. 9C. Note that a head 46a having a large diameter is formed at the tip of the lock pin 46, and the lock pin 46 tends to be retracted by the spring 44. The head 46a is locked to the lower end of the rear leg 3B. Therefore, the advanced state remains and the locked state is maintained.

  In order to release this locked state, it is only necessary to place the hand on the backrest 2 and tilt it further backward. When the backrest 2 is further tilted backward, as shown in FIG. 9 (d), the lower end of the rear leg 3B rises so that it is positioned above the head 46a of the lock pin 46, and the engagement with the rear leg 3B. Since the lock is released and the lock pin 46 is in a free state, the lock pin 46 is returned by the spring 44 and the foot lever 41 is not depressed. As a result, the leg 3 is automatically tilted forward by the tension spring 6 and assumes the retracted posture.

Next, the configuration of the semi-stop position will be described.
As described above, the front leg 3 </ b> A and the rear leg 3 </ b> B are connected via the seat support 4 and the base 5, but the rear leg 3 </ b> B is connected to the front leg 3 </ b> A by a lever 17. That is, the pin 17a at one end of the lever 17 is locked in the guide groove 18a of the locking member 18 fixed to the front leg 3A.
In the state of the retracted position where the leg 3 is tilted forward, the pin 17a is positioned at the rightmost end of the guide groove 18a, and moves to the left end side of the guide groove 18a as the leg 3 is tilted backward. When the pin 17a is located at the leftmost end, it is necessary to lean backrest 2 considerably in order to further tilt backward.
In this semi-stop position, the seat 1 is in a substantially flat state, which is appropriate for a person who sits without playing back against the backrest 2 and plays a game.

Next, the operation of the gaming chair configured as described above will be described.
When the player is not seated on the chair, the seat 1 is held in the retracted posture in which the seat 1 faces the game table and the legs 3 are tilted forward (state shown in FIG. 1).
When sitting on a chair, first, place your hand on the backrest 2 and pull it backward (in the direction away from the game table). As a result, the leg 3 tilts backward with the connecting pins 7c and 7d as fulcrums, and the seat 1 moves rearward and the seat surface becomes flat. Accordingly, the rotating cam 12a at the lower end of the rotating shaft 12 is guided away from the back portion 14b of the cam surface 14a of the stroke cam 14. Further, the pin 17a of the lever 17 moves in the guide groove 18a.
Until the pin 17a comes into contact with the left end of the guide groove 18a, only the urging force of the tension spring 6 is used, so that the pin 17a can be tilted relatively lightly.

While the rotary cam 12a is moving in the back portion 14b of the stroke cam 14, the seat 1 cannot be rotated, but after that, the rotation can be gradually performed.
After tilting back to some extent, the seat 1 is rotated 90 degrees, seated sideways from the side, and the seat 1 is rotated toward the game table as it is.
When the pin 17a comes into contact with the left end of the guide groove 18a when the pin 17a is tilted backward without turning against the backrest 2 after turning, it becomes a semi-stop position and does not tilt backward any further. FIG. 12 shows the state at this time, and the seat 1 becomes substantially flat. This state is suitable for a person who sits against the backrest 2 (not many women). In this case, the rear leg 3B is naturally expanded and contracted by the compression spring 23 and has elasticity.

On the other hand, when leaning backward against the backrest 2, it tilts to the semi-stop position without much leaning, but when leaning further, it is necessary to put weight on the backrest 2. When the vehicle is further tilted backward from the semi-stop position, the locking portion 3C at the lower end of the front leg 3A comes into contact with the base 5 and the state shown in FIG. 10 is obtained. A normal player almost plays in this state. Note that the front leg 3A cannot be tilted backward any further.
When the seat back in FIG. 10 is further leaned against the backrest 2, the compression spring 23 of the rear leg 3B is further compressed, and the support bar 22 moves downward. When the lower end comes into contact with the locking member 24 (the state shown in FIG. 11), it cannot be tilted backward.

In order to leave the seat, it is only necessary to turn 90 degrees to the left or right and get off the seat 1 with the legs 3 tilted backward.
When the player leaves the chair, the leg 3 is moved forward by the tension spring 6 and the rotating cam 12a is engaged with the cam surface 14a of the stroke cam 14 so that the seat 1 is turned forward. Further, at this time, the torsion coil spring 15 urges the seat 1 to face forward. Here, the torsion coil spring 15 is used auxiliary.
When the leg 3 is in the retracted position, the rotary cam 12a is positioned at the foremost end of the cam surface 14a of the stroke cam 14, and the seat 1 is fixed at a position facing forward. Therefore, in the retracted position, the seat 1 is neither rotated nor rotated.

When the leg 3 moves forward and approaches the retracted position, the buffer means 30 acts. That is, as the rear leg 3B tilts forward, the rotating cam 33 rotates and presses the sliding cam 32, and the sliding piece 32a is guided to the cradle 31 and the axial direction of the connecting pin 7d (relative to the chair). And the coil spring 35 is compressed accordingly.
This acts as a rotation resistance of the rotation cam 33 and acts as a brake for the forward tilt movement of the rear leg 3B, so that the leg 3 tilts to the retracted position while decelerating. And if the latching | locking part 3D of the upper end of 3 A of front legs contact | abuts to the seat support body 4, it will stop.

On the other hand, for example, when the nails of the game table are sequentially adjusted, there is a case where the chair is in the retracted position in the work on the store side, and it is necessary to lock the chair in the raised state.
In this case, stand in the vicinity of the forward tilt lock device 40 of the chair in the retracted position, put the hand on the backrest 2 and push it backward, and when the seat 1 is substantially horizontal, depress the foot lever 41 to release the lock pin 46. The forward tilt is locked by engaging with the lower end of the rear leg 3B (see FIG. 9). If this operation is sequentially performed for other chairs, the chairs can be similarly held up.

When the adjustment of the nail is completed and the chair is returned to the retracted position, the backrest 2 is put in hand and further tilted backward. By this operation, the lock pin 46 is unlocked from the rear leg 3B and is retracted by the spring 44 (at the same time, the foot lever 41 also returns). Therefore, if the hand is released from the backrest 2, the tension spring 6 Tilt forward to retracted position.
Since the forward tilt lock device 40 is easy to handle in this way, a large number of chairs can be raised and returned to the retracted position for a short time and standing, so that the Work such as adjustment and replacement can be performed efficiently.

Next, the case where the above-mentioned chair for the game hall is stored, transported, and further installed in the game hall will be described based on FIG. 1, FIG. 2 and FIG.
The game room chair is in the state shown in FIG. 1 when assembled. However, unless the base 5 is fixed to the floor or the like, the chair is not stable and difficult to handle in storage and transportation. In the present invention, a seat 1 integrated with the backrest 2 and a leg unit are provided, and a mounting base 50 is further provided for installation in a game hall. The base 5 is provided with a flange 5a so that the base 5 is reliably supported at an accurate position.

The leg unit includes a leg 3, a seat support 4, a base 5, a bracket 11 attached to the back surface of the seat 1, and a torsion coil spring 15. That is, the upper part is assembled from the bracket 11 to the lower part to the base 5, and is in a state where the lower end mounting base 50 is removed in FIG. 2.
Thus, since it divided | segmented, it can be stored and transported in a stable state. Moreover, assembly can be completed easily with only a spanner. In addition, when carrying into the amusement hall, only the mounting base 50 is attached in advance to the predetermined position with anchor bolts in advance, and then the leg units are sequentially carried in and attached to the mounting base 50 with bolts. Simple and quick.
