The problem to be solved by the invention

However, the conventional technology is a mechanism that locks the door by restricting the movement by contacting the door leaf. Therefore, after the driving force is transmitted from the motor to the door leaf, the door leaf is restricted, and therefore, movement of the door leaf with weight needs to be restricted. Therefore, in order to make the door immobile, a large restraining force is required. Therefore, the restricting member requires high rigidity and strength, and the device tends to increase in strength and size.

However, there is a demand to be able to lock the door with a smaller restrictive force. Furthermore, in a double-leaf sliding door, there is a demand not to lock the other door leaf when one door leaf is locked.

An object of the present invention is to provide an OoSL capable of restraining with a smaller restraining force before driving force is transmitted to the door leaf than directly restraining a heavy door leaf.

Detailed ways

Hereinafter, embodiments of the manual locking device and the door device for railways according to the present invention will be described based on the drawings.

FIG. 1 is a schematic view of the vicinity of the landing of the railway vehicle in this embodiment viewed from the vehicle width direction. Fig. 2 is a front view showing an open state of the railway door device and the manual locking device according to the present embodiment. Fig. 3 is a perspective view showing the vicinity of a locking portion of the manual locking device according to the present embodiment. Fig. 4 is a perspective view showing the vicinity of a locking portion of the manual locking device according to the present embodiment. In each figure, reference numeral 100 is a gate apparatus for railways.

In the following embodiments, an example including a pair of double-drawn doors for opening and closing the landing of a railway vehicle (vehicle) will be described as a railway door device.

In addition, in the following description, terms such as "parallel", "orthogonal", "center", and "coaxial" indicating a relative or absolute arrangement are not limited to strictly meaning such an arrangement. For example, the above term also includes a state of being relatively displaced by a tolerance, an angle, and a distance to the extent that the same function can be obtained. In addition, in the drawings used in the following description, the scale of each member is appropriately changed so that each member may be recognizable in size.

As shown in FIG. 1 , the railway door device 100 according to the present embodiment is disposed above the landing 200 . The railway door device 100 includes a manual locking device 101 .

As shown in FIGS. 2 to 4 , the railway door device 100 has a pair of doors 2 , a drive source 3 , a transmission mechanism 4 , a moving part 5 , a restricting part 6 , an operating part 7 , a locking part 8 , and a locking restricting part 9 . .

The transmission mechanism 4 , the moving part 5 , the regulating part 6 , the operating part 7 , the locking part 8 , and the locking regulating part 9 constitute a manual locking device 101 .

In addition, in the following description, it demonstrates using the orthogonal coordinate system of Y, X, and Z as needed. The Y direction coincides with the width direction of the vehicle. The X direction coincides with the front-rear direction of the vehicle. The Z direction represents the height direction (gravity direction) of the vehicle perpendicular to the Y direction and the X direction.

In the following description, in the Y direction, the X direction, and the Z direction, the side indicated by the arrow in the drawing is referred to as the plus (+) side, and the side opposite to the arrow is referred to as the minus (−) side. The +Y side corresponds to the inside in the vehicle width direction (direction toward the vehicle from the outside), and the −Y side corresponds to the outside in the vehicle width direction (direction toward the outside from the vehicle). The +Z side corresponds to the upper side in the direction of gravity, and the −Z side corresponds to the lower side in the direction of gravity.

As shown in FIG. 1, the door apparatus 100 for railways has the double door 2 which slides in the X direction, and opens and closes the landing 200. As shown in FIG. As shown in FIG. 2 , the door 2 includes a door leaf 10 and a door hanger (connection and movement portion) 11 connected to the door leaf 10 .

The door 2 is defined by a guide rail not shown so as to move along an opening and closing path for opening and closing the landing 200 of the vehicle. The door 10 reciprocates in the X direction between a fully closed position and a fully opened position. The door 2 is driven to open and close by a drive source 3 .

The driving source 3 outputs a driving force for moving the door 2 . For example, drive source 3 is a motor. The output shaft of the motor rotates about an axis along the X direction. For example, the output shaft of the motor is rotatable around an axis line along the X direction (forward and reverse rotation is possible). The forward and reverse rotation of the motor causes the door 10 to reciprocate in the X direction between the fully closed position and the fully opened position.

The transmission mechanism 4 transmits the driving force from the drive source 3 to the door 10 to move the door 10 between the fully open position and the fully closed position. The transmission mechanism 4 includes, for example, a power conversion mechanism 41 that converts the direction of the driving force from the drive source 3 and an endless belt 42 extending in the front-rear direction (X direction) of the vehicle.

The power conversion mechanism 41 converts the rotation of the output shaft of the motor about the axis along the X direction into the rotation about the axis along the vehicle width direction (Y direction) of the vehicle. The power conversion mechanism 41 includes a gear 43 that rotates about an axis along the vehicle width direction (Y direction) of the vehicle. A pulley 44 rotatable about an axis parallel to the rotation axis of the gear 43 (axis along the Y direction) is provided at a position separated from the gear 43 in the X direction.

The belt 42 is stretched over the gear 43 and the pulley 44 . The belt 42 moves (revolves) around the gear 43 and the pulley 44 in conjunction with the rotation of the gear 43 . The moving part 5 that moves together with the belt 42 is attached to the belt 42 . The moving part 5 reciprocates in the front-rear direction (X direction) of the vehicle. A door hanger 11 is connected to the moving part 5 . The opening and closing path of the door hanger 11 is defined by a guide rail not shown.

The moving part 5 reciprocates in the front-rear direction (X direction) of the vehicle between the fully-closed position and the fully-opened position corresponding to the movement of the door 10 between the fully-closed position and the fully-opened position. The moving part 5 is attached to the outer side of the belt 42 stretched over the gear 43 and the pulley 44 .

In addition, when viewed from the Y direction, the position surrounded by the belt 42 and close to the gear 43 and the pulley 44 is referred to as the inner side of the belt. On the other hand, the position on the side opposite to the gear 43 and the pulley 44 with respect to the belt 42 is referred to as the outer side of the belt.

The fully closed corresponding position and the fully opened corresponding position of the moving part 5 are located between the gear 43 and the pulley 44 in the front-rear direction (X direction) of the vehicle.

As shown in FIG. 2 , the moving part 5 has an upper moving part 51 attached to the upper side of the belt 42 and a lower moving part 52 attached to the lower side of the belt 42 .

In FIG. 2 , the fully closed corresponding position of the upper moving portion 51 is a position on the right side close to the pulley 44 in the front-back direction (X direction) of the vehicle. The fully open corresponding position of the upper moving part 51 is a position close to the left side of the gear 43 .

Similarly, in FIG. 2 , the fully open corresponding position of the lower moving portion 52 is a position close to the right side of the pulley 44 in the front-rear direction (X direction) of the vehicle. The fully closed corresponding position of the lower moving part 52 is a position close to the left side of the gear 43 .

The left door leaf 10 shown in FIG. 2 is connected to the upper moving part 51 via the door hanger 11 . The right door leaf 10 shown in FIG. 2 is connected to the lower moving part 52 via the door hanger 11 .

The upper moving part 51 and the lower moving part 52 move opposite to each other and move the same distance as the belt 42 moves in the front-rear direction (X direction) of the vehicle. Therefore, the fully closed corresponding position of the upper moving part 51 and the fully closed corresponding position of the lower moving part 52 are equidistant from the center of the landing 200 in the front-rear direction (X direction) of the vehicle. Similarly, the fully open corresponding position of the upper moving part 51 and the fully open corresponding position of the lower moving part 52 are equidistant from the center of the landing 200 in the front-rear direction (X direction) of the vehicle.

Both the upper moving part 51 and the lower moving part 52 have a rectangular outer shape when viewed from the vehicle width direction (Y direction) of the vehicle.

As shown in FIGS. 2 to 4 , the restriction unit 6 has a right restriction unit 61 and a left restriction unit 62 corresponding to the upper movement unit 51 and the lower movement unit 52 . In addition, "right" and "left" are defined based on FIG. 2, and they are called for convenience.

The right restricting portion 61 is rotatably supported by a rotation shaft 61 a having a rotation axis extending in the Y direction. The right restricting portion 61 is rotatably movable around the rotation shaft 61a between a locked position where the right restricting portion 61 is in contact with the upper moving portion 51 and an unlocked position where the right restricting portion 61 is not in contact with the upper moving part 51, and does not hinder the movement of the upper moving part 51.

The rotating shaft 61a is arranged at a position close to the upper moving part 51 located in the fully closed corresponding position. When viewed from the Y direction, the rotation shaft 61 a is disposed at a position close to the −Z direction and the −X direction with respect to the upper moving portion 51 located at the fully closed corresponding position.

The right restricting part 61 has a 1st arm 61b and a 2nd arm 61c extended in opposite directions from the rotation shaft 61a.

The right restricting portion 61 rotates between an unlocked position where the first arm 61b and the second arm 61c extend in the X direction and a locked position where the first arm 61b and the second arm 61c extend in the X direction. The arm 61c extends in the Z direction. The right restricting portion 61 is rotated about 90° clockwise around the rotation shaft 61 a from the unlocked position shown in FIG. 2 to be in the locked position.

In the unlocked position, the first arm 61b is located at a position extending in the −X direction from the rotation shaft 61a. The first arm 61b is located at a position extending in the +Z direction from the rotation shaft 61a in the locked position.

When viewed from the Y direction, the first arm 61b is located inside the belt 42 when located at the unlocked position. When viewed from the Y direction, the first arm 61 b rotates to a position outside the belt 42 when moving from the unlocked position to the locked position.

The 1st arm 61b has the movement restriction|limiting part 61d which contacts the upper movement part 51 at a locked position, and prevents the movement of the upper movement part 51 to -X direction. The movement control part 61d contacts the front surface 51a of the -X direction of the upper movement part 51 with respect to the upper movement part 51 located in the fully closed corresponding position (refer FIG. 7 mentioned later). That is, the movement restricting portion 61d is located outside the belt 42 at the locked position, and is separated from the rotation shaft 61a by a distance capable of contacting the front surface 51a of the upper moving portion 51 .

The movement restricting portion 61d is located on the upper surface facing the +Z direction of the first arm 61b at the unlocked position. The movement restricting portion 61d has a surface shape parallel to the front surface 51a of the upper movement portion 51 at the locked position so as to contact the front surface 51a of the upper movement portion 51 with as large an area as possible. That is, the movement restricting portion 61d has a surface along the YZ direction at the locked position.

When viewed from the Y direction, the rotation shaft 61 a is arranged at a position closer to the −X direction than the front surface 51 a of the upper moving portion 51 located at the fully closed corresponding position.

The 1st arm 61b is connected to the lock part 8 mentioned later via the rotation shaft 61f provided in the position separated from the rotation shaft 61a. The rotation shaft 61f has a rotation axis in the Y direction parallel to the rotation shaft 61a. The movement restricting portion 61d is located in the +Z direction relative to the rotation axis 61f when the first arm 61b is located in the unlocked position. In the right restricting portion 61, when located in the locked position, the rotating shaft 61f is located in the +Z direction relative to the rotating shaft 61a.

Likewise, the second arm 61c is at a position extending in the +X direction from the rotation shaft 61a at the unlocked position. The second arm 61c is located at a position extending in the −Z direction from the rotation shaft 61a in the locked position.

When viewed from the Y direction, the second arm 61c is located inside the belt 42 when located at the unlock position. When viewed from the Y direction, the second arm 61c rotates to a position where it does not come into contact with the belt 42 or a position where it does not interfere with the belt 42 when moving from the unlocked position to the locked position.

The second arm 61c has an engaged portion 61e that is in contact with a later-described lock regulating portion 9 at the unlocked position to prevent clockwise rotational movement of the right regulating portion 61 around the rotation shaft 61a. In a state where the engaged portion 61e is in contact with the lock regulation portion 9 , the right regulation portion 61 is restricted by the lock regulation portion 9 and prevented from rotating.

The left restricting portion 62 is symmetrical to the right restricting portion 61 . Specifically, when viewed from the Y direction, the left restricting portion 62 and the right restricting portion 61 are arranged point-symmetrically with respect to the midpoint between the rotation axis of the gear 43 and the rotation axis of the pulley 44 .

The left restricting portion 62 is rotatably supported by a rotation shaft 62 a having a rotation axis extending in the Y direction. The left restricting portion 62 is rotatably movable around the rotation shaft 62a between a locked position where the left restricting portion 62 is in contact with the lower moving portion 52 and an unlocked position where the left restricting portion 62 is not in contact with the lower moving part 52 and does not hinder the movement of the lower moving part 52 .

The rotating shaft 62a is arranged at a position close to the lower moving part 52 at the fully closed corresponding position. When viewed from the Y direction, the rotation shaft 62a is arranged at a position closer to the +Z direction and the +X direction than the lower moving portion 52 located at the fully closed corresponding position.

The left restricting part 62 has the 1st arm 62b and the 2nd arm 62c extended in opposite directions from the rotation shaft 62a.

The left restricting part 62 rotates between an unlocked position where the first arm 62b and the second arm 62c extend in the X direction and a locked position where the first arm 62b and the second arm 62c extend in the X direction. The arm 62c extends in the Z direction. The left restricting portion 62 is rotated about 90° clockwise about the rotation shaft 62 a from the unlocked position shown in FIG. 2 to be in the locked position.

The first arm 62b is at a position extending in the +X direction from the rotation shaft 62a at the unlocked position. The first arm 62b is located at a position extending in the −Z direction from the rotation shaft 62a in the locked position.

When viewed from the Y direction, the first arm 62b is located inside the belt 42 when located at the unlocked position. When the first arm 62b moves from the unlocked position to the locked position, it rotates to a position outside the belt 42 .

The 1st arm 62b has the movement restriction|limiting part 62d which contacts the lower movement part 52 and prevents the movement of the lower movement part 52 to + X direction, when it exists in a locked position. The movement restricting part 62d is in contact with the front surface 52a of the +X direction of the lower moving part 52 with respect to the lower moving part 52 located in the fully closed corresponding position (refer FIG. 7 mentioned later). That is, the movement restricting portion 62d is located outside the belt 42 at the locked position, and the movement restricting portion 62d is separated from the rotation shaft 62a by a distance capable of contacting the front surface 52a of the lower moving portion 52 .

The movement restricting part 62d is located in the lower surface facing -Z direction of the 1st arm 62b at an unlocked position. The movement restricting part 62d has a surface shape parallel to the front surface 52a of the lower moving part 52 at the locked position so that as large an area as possible is in contact with the front surface 52a of the lower moving part 52 . That is, the movement restricting portion 62d has a surface along the YZ direction at the locked position.

When viewed from the Y direction, the rotation shaft 62a is arranged at a position closer to the +X direction than the front surface 52a of the lower moving part 52 at the fully closed corresponding position.

The 1st arm 62b is connected to the lock part 8 mentioned later via the rotation shaft 62f provided in the position spaced apart from the rotation shaft 62a. The rotation shaft 62f has a rotation axis in the Y direction parallel to the rotation shaft 62a. The movement restricting part 62d is located in the -Z direction rather than the rotating shaft 62f when the 1st arm 62b is located in an unlocked position. In the left restricting part 62, when located in the locked position, the rotating shaft 62f is located in the -Z direction rather than the rotating shaft 62a.

Likewise, the second arm 62c is at a position extending in the −X direction from the rotation shaft 62a in the unlocked position. The second arm 62c is located at a position extending in the +Z direction from the rotation shaft 62a at the locked position.

When viewed from the Y direction, the second arm 62c is located inside the belt 42 when located at the unlock position. The second arm 62c rotates to a position where it does not come into contact with the belt 42 or a position where it does not interfere with the belt 42 when moving from the unlocked position to the locked position.

The second arm 62c has an engaged portion 62e which, when located at the unlocked position, comes into contact with a later-described lock regulating portion 9 to prevent clockwise rotational movement of the left regulating portion 62 around the rotation shaft 62a. . In a state where the engaged portion 62e is in contact with the lock regulation portion 9 , the left regulation portion 62 is restricted by the lock regulation portion 9 and prevented from rotating.

The operation part 7 generates an operation force for operating the lock part 8 by manual operation.

As shown in FIGS. 3 and 4 , the operation unit 7 has an input unit 71 for manually inputting an operation force, and a conversion unit 72 for converting the direction of the operation force input from the input unit 71 and transmitting it to the upper lock unit 8 .

The input unit 71 is arranged at the center of the landing 200 in the X direction (see FIG. 1 ). The input unit 71 is located above the door 10 . The input part 71 has the input shaft 71a which engages with the lock key which is not shown in figure, and rotates.

The input shaft 71a has a rotation axis along the Z direction, and inputs an operating force vertically upward from the lower end. The input shaft 71 a is arranged at an equal distance from the rotation axis of the gear 43 and the rotation axis of the pulley 44 in the X direction. The input shaft 71a is arranged at the central position of the landing 200 in the X direction.

The conversion part 72 has the bevel gear 71b, 72b which transmits rotation between the input shaft 71a and the rotation shaft 81a of the lock part 8 mentioned later, and changes a transmission direction.

The bevel gear 71b is arranged near the upper end of the input shaft 71a. The bevel gear 72b is disposed on a rotation shaft 81a of the locking portion 8 described later. The rotation shaft 81a has a rotation axis along the Y direction. The bevel gear 71b and the bevel gear 72b mesh with each other, and transmit rotation from the input shaft 71a to the rotation shaft 81a.

As shown in FIGS. 2 to 4 , the upper lock portion 8 has: a first link 81 that rotates around a rotating shaft 81 a; and the left second link (second link) 83, one end of which is connected to the end of the first link 81.

The rotation shaft 81a has a rotation axis along the Y direction. The rotating shaft 81a is arrange|positioned at the center position of the landing 200 in the X direction. The rotation shaft 81 a is disposed equidistant from the rotation axis of the gear 43 and the rotation axis of the pulley 44 in the X direction. The rotating shaft 81 a is arranged inside the belt 42 when viewed from the Y direction.

The first link 81 has an arm 81 b extending in the +X direction and an arm 81 c extending in the −X direction around the rotation shaft 81 a at the unlock position.

The first link 81 can rotate 180° around the rotation axis 81a between the unlocked position and the locked position. Extending in opposite directions, in the locked position, the arms 81b, 81c extend in the X direction and face opposite to the unlocked position.

One end of a left second link (second link) 83 is connected to the tip of the arm 81b via a rotation shaft 81d. One end of a right second link (second link) 82 is connected to the tip of the arm 81c via a rotation shaft 81e.

At the tip of the arm 81c, a stop portion 81g is formed at a position farther from the rotation axis 81a than the rotation axis 81e. The stop part 81g stops the 1st link 81 at a locked position, and restrict|limits a rotation position. The stop portion 81g abuts against the stop regulating portion 84 at the locked position to restrict its position.

The arm 81c has a switch pressing portion in contact with the lock switch 103 at the tip. The switch pressing part can also be used as the stop part 81g. The lock switch 103 that is turned on by contacting the switch pressing portion detects that the first link 81 is in the locked position. That is, the lock switch 103 detects that the moving part 5 is located at the fully closed corresponding position and the restricting part 6 is located at the locked position.

As a result, the lock switch 103 can be used as a switch for detecting fully closed doors during normal vehicle operation.

The rotation shaft 81d is disposed at a position away from the rotation shaft 81a in the +X direction at the unlocked position. The rotation shaft 81e is arrange|positioned at the position separated toward -X direction from the rotation shaft 81a at an unlocked position. The separation distance between the rotation axis 81d and the rotation axis 81a is equal to the separation distance between the rotation axis 81e and the rotation axis 81a when viewed from the Y direction.

The left restricting part 62 is rotatably connected to the other end of the left second link (second link) 83 via a rotating shaft 62f. The left second link (second link) 83 extends in the −X direction from the rotation shaft 81 d at the unlocked position.

The right restricting part 61 is rotatably connected to the other end of the right second link (second link) 82 via a rotating shaft 61f. The right second link (second link) 82 extends in the +X direction from the rotation shaft 81e at the unlocked position.

In the unlocked position, the arm 81b extends in the +X direction from the rotation shaft 81a, and the left second link (second link) 83 extends in the −X direction from the rotation shaft 81d. In addition, in the unlocked position, the arm 81b is parallel to the left second link (second link) 83, and is arranged so as to overlap when viewed from the Y direction. Therefore, in the left second link (second link) 83 , a bent portion 83 a that is bent in the −Z direction from the rotating shaft 81 d and avoids the rotating shaft 81 e is formed at a position close to the rotating shaft 81 d.

In the unlocked position, the arm 81c extends in the −X direction from the rotation shaft 81a, and the right second link (second link) 82 extends in the +X direction from the rotation shaft 81e. In addition, in the unlocked position, the arm 81c is arranged in parallel to the second right link (second link) 82 and overlapped when viewed from the Y direction. Therefore, in the right second link (second link) 82 , a bent portion 82 a that is bent in the +Z direction from the rotation axis 81 e and avoids the rotation axis 81 d is formed at a position close to the rotation axis 81 e.

The rotating shaft 81a, the rotating shaft 81d, the rotating shaft 81e, the rotating shaft 61f, and the rotating shaft 62f are all parallel to each other along the Y direction.

The arm 81b, the left second link (second link) 83, and the left restricting portion 62 form a lock link that restricts the movement of the lower moving portion 52 at the fully closed corresponding position.

The arm 81c, the right second link (second link) 82, and the right restricting portion 61 form a lock link that restricts the movement of the upper moving portion 51 at the fully closed corresponding position.

By the operation force input from the operation part 7, the 1st link 81 rotates clockwise as shown in FIG.

In this locked position, the first link 81 is in a horizontal position, that is, a rotational position in which the arm 81b is in the -X direction and the arm 81c is in the +X direction around the rotation shaft 81a. At this time, as shown in FIG. 7 to be described later, the right second link 82 is positioned above the rotation axis 61 f in the Z direction relative to the rotation axis 81 e. Similarly, the left second link 83 is located on the lower side in the Z direction than the rotation axis 62f is relative to the rotation axis 81d.

That is, in the process of rotating from the unlocked position to the locked position, the first link 81 and the second links 82 and 83 are further rotated beyond the state of their dead centers aligned in a straight line. Therefore, when returning from the locked position to the unlocked position, the first link 81 and the second links 82 and 83 need to rotate beyond the dead center again.

The first link 81 is rotated counterclockwise by the operation force input from the operation part 7, and when it becomes the horizontal position shown in FIG. 2, the lock part 8 becomes an unlocked position.

The lock restricting part 9 enables locking by the lock part 8 only when the door 10 is in the fully closed position.

As shown in FIGS. 2 to 4 , the lock regulating portion 9 has a right locking regulating portion 91 and a left locking regulating portion 92 .

The right lock control part 91 can perform locking control on the right control part 61 .

The right upper lock restricting portion 91 is rotatably supported by a rotation shaft 91 a having a rotation axis extending in the Y direction. The right upper lock restricting portion 91 is rotatably movable around a rotation shaft 91 a between a lockable position and an unlockable position, at which the right upper lock restricting portion 91 is pressed by the upper moving portion 51 by being in contact with the upper moving portion 51 , at the unlockable position, the right upper lock restricting portion 91 is not in contact with the upper moving portion 51 or is not pressed by the upper moving portion 51 .

The rotating shaft 91a is arrange|positioned inside with respect to the belt 42 when seeing from a Y direction. The rotating shaft 91a is arranged at a position close to the upper moving part 51 located in the fully closed corresponding position. The rotation shaft 91 a is arranged at a position aligned with the −Z direction of the upper moving portion 51 located in the fully closed corresponding position and aligned with it in the X direction when viewed from the Y direction. A not-shown torsion spring is attached around the rotation shaft 91a. The torsion spring urges the right upper lock restricting portion 91 counterclockwise about a rotation axis 91 a in FIG. 2 .

The right upper lock regulating portion 91 is a cam having a first arm 91b extending in the +Z direction from the rotation axis 91a and an engaging portion 91h extending in the −Z direction on the base end side of the first arm 91b . The X direction protrudes.

The first arm 91 b has a pressed portion 91 d at the tip position, and the pressed portion 91 d is pressed by the upper moving portion 51 by contacting the upper moving portion 51 .

The pressed portion 91d is formed to protrude in the -X direction from the tip of the first arm 91b extending in the +Z direction from the rotation shaft 91a. When the pressed portion 91d is pressed in the +X direction, the first arm 91b can rotate and move from the lockable position to the lockable position around the rotation shaft 91a. The pressed portion 91d contacts and is pressed against the forward front surface 51b when the upper moving portion 51 advances in the +X direction. The first arm 91b returns from the lockable position to the unlockable position by the torsion spring surrounding the rotation shaft 91a when the pressing force from the upper moving part 51 disappears and the front surface 51b is not in contact with the pressed part 91d.

The right upper lock restricting portion 91 is rotatable around the rotation shaft 91a between an unlockable position in which the tip of the first arm 91b extends in the +Z direction and a lockable position in which the first arm 91b extends in the +Z direction. The top end of the arm 91b is inclined in the +X direction compared to the lockable position. The right upper lock restricting portion 91 rotates clockwise around the rotation shaft 91a from the unlockable position shown in FIG. 2 to move to the lockable position (see FIGS. 5 to 7 described later).

When located at the unlockable position, the engaging portion 91h comes into contact with the engaged portion 61e and prevents the rotational movement of the right restricting portion 61 . When located at the lockable position, the engaging portion 91h is separated from the engaged portion 61e without hindering the movement of the right restricting portion 61 .

In the right upper lock restricting part 91, by pressing from the upper moving part 51 to the pressed part 91d, the first arm 91b rotates to the lockable position, and the contact between the engaging part 91h and the engaged part 61e is released and Locking can be performed by the right restricting part 61 .

The left lock control part 92 is provided in point symmetry with the right lock control part 91 .

Specifically, when viewed from the Y direction, the left upper lock restriction portion 92 and the right upper lock restriction portion 91 are arranged point-symmetrically with respect to the midpoint between the rotation axis of the gear 43 and the rotation axis of the pulley 44 .

The left lock control part 92 can perform lock control on the left control part 62 . The left upper lock restricting portion 92 is rotatably supported by a rotation shaft 92a having a rotation axis extending in the Y direction. The left upper lock restricting part 92 can rotate around the rotation shaft 92a between a lockable position and an unlockable position. At the lockable position, the left upper lock restricting part 92 is in contact with the lower moving part 52 to be pressed by the lower moving part 52, In the unlockable position, the left upper lock restricting portion 92 is not in contact with the lower moving portion 52 or is not pressed by the lower moving portion 52 .

The rotating shaft 92a is arrange|positioned inside with respect to the belt 42 when seeing from a Y direction. The rotating shaft 92a is arranged at a position close to the lower moving part 52 located in the fully closed corresponding position. The rotation shaft 92a is arranged at a position aligned with the +Z direction of the lower moving part 52 located in the fully closed corresponding position when viewed from the Y direction and aligned with it in the X direction. A not-shown torsion spring is attached around the rotation shaft 92a. The torsion spring urges the left upper lock restricting portion 92 counterclockwise about a rotation axis 92 a in FIG. 2 .

The left upper lock restricting portion 92 is a cam having a first arm 92b extending in the −Z direction from the rotation axis 92a, a second arm 92c extending in the +Z direction from the rotation axis 92a, and an engaging portion 92h. It extends in the Z direction, and this engagement portion 92h protrudes in the +X direction on the base end side of the first arm 92b.

The first arm 92 b has a pressed portion 92 d at the tip position, and the pressed portion 92 d is pressed by the lower moving portion 52 by contacting the lower moving portion 52 . The pressed portion 92d is formed to protrude in the +X direction from the tip end of the first arm 92b extending in the −Z direction from the rotation shaft 92a.

When the pressed portion 92d is pressed in the −X direction, the first arm 92b can rotate and move from the lockable position to the lockable position around the rotation shaft 92a. The pressed portion 92d contacts and is pressed against the forward front surface 52b when the lower moving portion 52 advances in the −X direction. The first arm 92b returns from the lockable position to the unlockable position by the torsion spring surrounding the rotation shaft 92a when the pressing from the lower moving part 52 disappears and the front surface 52b is not in contact with the pressed part 92d.

The second arm 92c has a switch pressing portion 92e in contact with the full close switch 102 at the tip. The full-close switch 102 that has been turned on by contact with the switch pressing portion 92e detects that the lower moving portion 52 is located at the fully-closed corresponding position and that the left upper lock regulating portion 92 is located at the lockable position. That is, the fully closed switch 102 detects that the moving part 5 is located at the fully closed corresponding position and that the lock regulating part 9 is located at the lockable position.

The left upper lock restricting part 92 is rotatable around the rotation shaft 92a between an unlockable position in which the tip of the first arm 92b extends in the -Z direction and a lockable position in which the first arm 92b extends in the -Z direction. The tip of the arm 92b is inclined in the −X direction from the unlockable position. The left lock control part 92 rotates clockwise around the rotation shaft 92a from the lock-unlockable position shown in FIG. 2, and moves to the lockable position (refer to FIG. 5-FIG. 7 mentioned later).

When located at the unlockable position, the engaging portion 92h comes into contact with the engaged portion 62e and prevents the rotational movement of the left restricting portion 62 . When located at the lockable position, the engaging portion 92h is separated from the engaged portion 62e without hindering the movement of the left restricting portion 62 .

In the left upper lock regulating part 92, by pressing from the lower moving part 52 to the pressed part 92d, the first arm 92b rotates to the lockable position, and the contact between the engaging part 92h and the engaged part 62e is released and Locking can be performed by the left restricting part 62 .

Simultaneously, the 2nd arm 92c rotates integrally with the 1st arm 92b, and the switch pressing part 92e contacts the full close switch 102. As shown in FIG. Thereby, the fully closed switch 102 detects and outputs that it is in the fully closed corresponding position.

The full close switch 102 is connected with the interlock circuit that transmits the full close signal when all doors 2 are fully closed, and when utilizing the locking portion 8 to lock, the full close switch 102 bypasses the interlock circuit to be able to always Connected in a way that transmits a fully closed signal.

In the door device 100 for railway according to the present embodiment, the moving part 5 does not come into contact with the lock regulating part 9 in the state where the door 2 shown in FIG. 2 is opened or at least not fully closed. Therefore, the lock regulating portion 9 maintains the unlockable position, and the movement restriction of the regulating portion 6 by the lock regulating portion 9 is maintained. Therefore, since the restricting part 6 maintains the unlocked position, manual locking is restricted.

And, as shown in FIG. 5 , in the state where the door 2 is closed, that is to say, when the door 10 has reached the fully closed position, the moving part 5 abuts against the lock control part 9 , and therefore the lock control part 9 is in a state where the door 2 is closed. Lockable position. As a result, the operation restriction of the restriction part 6 by the lock restriction part 9 is released. At the same time, the fully closed switch 102 detects that the door leaf 10 has reached the fully closed position.

Here, when locking the door 2 manually, it is necessary to enable locking only when the door 10 has reached the fully closed position.

In this state, when the lock is performed by the operation unit 7, the input shaft 71a is rotated by a key not shown. This operation force is transmitted to the bevel gear 71b, the bevel gear 72b, and the rotation shaft 81a, and the first link 81 of the locking part 8 rotates.

When the door leaf 10 is in the fully closed position, when the locking operation is performed by the operating portion 7, the first link 81 of the locking portion 8 passes through the unlocked position shown in FIG. 6 from the unlocked position shown in FIGS. 2 to 5 . Rotate to the locked position shown in Figure 7 from the halfway state shown.

The stop portion 81g abuts against the stop regulating portion 84 to stop rotation at the locked position. As the first link 81 rotates, the second links 82 and 83 and the right restricting portion 61 and the left restricting portion 62 also rotate in conjunction with each other. As a result, in the locked position, as shown in FIG. 7 , the second links 82 and 83 are in the following position with respect to the first link 81 facing in the horizontal direction (X direction): the ends on the restricting portion 6 side The rotation axes 61f and 62f of the first link 81 are farther from the first link 81 in the Z direction than the rotation axes 81d and 81e of the ends on the first link 81 side.

That is, as shown in FIG. 7 , with respect to the first link 81 , the right second link 82 is in the locked position when it is rotated by an angle θ2 exceeding 180° around the rotation axis 81 e. In addition, the state where the left second link 83 has rotated beyond the angle θ3 of 180° around the rotation axis 81 d with respect to the first link 81 is in the locked position.

With respect to the first link 81, the right second link 82 is inclined upward by an angle θ2 with respect to the horizontal direction around the rotation axis 81e. This is because the right restricting portion 61 is rotated to the locked position where the rotation axis 61f of the right restricting portion 61 is located outside the belt 42 and the rotation axis 61f is located in the +Z direction with respect to the rotation axis 61a.

With respect to the first link 81, the left second link 83 is inclined downward by an angle θ3 with respect to the horizontal direction around the rotation axis 81d. This is because the left restricting portion 62 has rotated to the locked position where the rotating shaft 62f of the left restricting portion 62 is located outside the belt 42 and the rotating shaft 62f is located in the -Z direction with respect to the rotating shaft 62a.

In the locked position, when an attempt is made to open the door 2, the moving part 5 moves from the fully closed corresponding position. In this case, the moving part 5 moves toward the fully open corresponding position.

Then, in the right regulating portion 61 , the movement regulating portion 61 d is pressed in the −X direction by the front surface 51 a of the upper moving portion 51 . Then, when viewed from the +Y direction, a force that rotates the right restricting portion 61 counterclockwise around the rotation axis 61 a acts. This force is transmitted to the second link 82 of the upper lock portion 8 . At this time, the force acts along the axis of the second link 82 and is transmitted from the rotation shaft 81e to the first link 81 .

As described above, in the locked position, the right second link 82 is at an angular position beyond the dead center with respect to the first link 81 . Therefore, the line of action of the force for attempting to open the door 2 transmitted from the second right link 82 to the first link 81 is directed in the locking rotation direction, and the rotation of the first link 81 is regulated by the stop regulating portion 84 .

Similarly, in the left regulating part 62 , the movement regulating part 62 d is pressed in the +X direction by the front surface 52 a of the lower moving part 52 . Then, when viewed from the +Y direction, a force that rotates the left restricting portion 62 counterclockwise around the rotation axis 61 a acts. This force is transmitted to the second link 83 of the upper lock portion 8 . At this time, the force acts along the axis of the second link 83 and is transmitted from the rotation shaft 81d to the first link 81 .

As described above, in the locked position, the left second link 83 is at an angular position beyond the dead center with respect to the first link 81 . Therefore, the line of action of the force for attempting to open the door 2 transmitted from the left second link 83 to the first link 81 is directed in the locking rotation direction, and the rotation of the first link 81 is regulated by the stop regulating portion 84 .

That is, unless the second links 82 and 83 are rotated beyond the dead center, they cannot be rotated in the unlocking direction. Therefore, the manually locked state can be maintained without adding another structure.

Then, the locked state is maintained in a point-symmetrical state with respect to the rotation axis 81 a when viewed from the Y direction by the first link 81 , the second link 82 , and the second link 83 in such a state beyond the dead center. Therefore, even when the pressing force of the moving part 5 or the pressing force of the regulating part 6 in the unlocking direction is large, the locked state can be easily maintained.

With regard to the railway door device 100 of the present embodiment, in the manual locking device 101, the belt 42 of the transmission mechanism 4 that moves integrally with the door leaf 10 is simultaneously locked by the right restricting part 61 and the left restricting part 62 of the restricting part 6, respectively. The upper moving part 51 and the lower moving part 52 of the installed moving part 5 make the door leaf 10 unable to open and close. Thereby, compared with the case of directly locking a door leaf, it can lock with a smaller restrictive force.

In the door device 100 for railway according to the present embodiment, in the case of manual locking, in the manual locking device 101 , the locking control part 9 comes into contact with the control part 6 to prevent locking operation. Unless the door 10 is in the fully closed state where the door 10 is at the fully closed position, the lock regulating portion 9 is not separated from the regulating portion 6 . Therefore, when the door 10 is not in the fully closed position, it can be restricted so that manual locking cannot be performed.

Moreover, each double-opening door 10 can be simultaneously locked by the key operation of the operation part 7, and this locked state can be maintained.

Thus, for example, even when the door cannot be driven to close due to driving of the vehicle or the like in an emergency such as when the door 2 fails, the locking operation in the fully closed state can be reliably performed manually. In particular, even when the door 10 is damaged, it can be reliably locked compared to a mechanism that directly locks the door 10, thereby improving safety.

In addition, since the door 10 cannot be locked when it is in a position other than the fully closed position, it is possible to prevent malfunction and improve safety. Compared with the mechanism that directly locks the door 10, it can be reliably locked with smaller components and with a smaller restrictive force.

According to the above configuration, the locking regulating portion 9 abuts on the moving portion 5 and moves from the locking regulating position to the unlocking regulating position, whereby the locking operation of the regulating portion 6 and the locking portion 8 can be performed. Therefore, manual locking can be performed only in a fully closed position, without providing a locking control part (closing plate) over the whole area|region in an opening-closing direction.

Furthermore, the locking regulating portion may include: an engaging portion that contacts the engaged portion to prevent the movement of the regulating portion; and a pressed portion that can be pressed in the closing direction by the moving portion when the door reaches the fully closed position. And the contact between the engaging portion and the engaged portion is released.

Thereby, unlocking/locking can be switched only by whether the moving part presses the pressed part, the number of parts can be reduced, and the operational reliability can be improved.

In the manual locking device of the present invention, the lock limiting portion may be a cam having a pressed portion and an engaging portion, and the cam rotates when the pressed portion is pressed, thereby releasing the engaged portion and the engaging portion. contact between.

Thereby, the contact between the engaged part and the engaging part and its release can be reliably switched.

In the manual locking device of the present invention, a fully closed switch for detecting that the door has reached the fully closed position may be provided. The cam may further include a switch pressing portion that rotates when the pressed portion is pressed, thereby pressing the fully closed switch.

Accordingly, it is possible to detect that the door is in a fully closed state without directly detecting the position of the door.

In the manual locking device of the present invention, it may be provided on a plurality of doors for opening and closing a plurality of landings of a railway vehicle. The fully closed switch may be connected to an interlock circuit that transmits a fully closed signal when all doors are fully closed, and the fully closed switch may bypass the interlock when the locking portion is locked by manually operating the operating portion. The circuit is connected in such a way that it always transmits a fully closed signal.

Thereby, it is possible to perform lock detection at an emergency time when the lock is locked by manual operation. Furthermore, it can be used as a fully closed switch for detecting fully closed during normal door opening and closing.

In the manual locking device of the present invention, the locking portion may include: a first link that is rotated by the operating force of the operating portion; and a second link that has one end connected to the end of the first link connected and the other end is connected to the restricting part, the first link rotates from the unlocked position toward the locked position, and the first and second links become the locked position at a position beyond the dead center.

As a result, the lock is performed at a position where the angle between the first link and the second link exceeds the dead center, and therefore, there is no need for a structure for fixing the first link and the second link at the locked position. , and can be locked reliably.

In the manual locking device of the present invention, the second link may extend along the moving direction of the moving part at the locked position.

As a result, when the moving part tries to unlock the lock, the second link is pressed in the direction in which the second link extends, and the locked state can be easily maintained even if a large force is applied.

In the manual locking device of the present invention, the restricting portion connected to the second link may be in contact with a position of the moving portion toward the fully open corresponding position when the door is at the fully closed position.

As a result, the restricting portion is in direct contact with the forward portion in the moving direction from the fully closed position, which is one end of the moving range of the moving portion, and the moving portion is restricted. Therefore, the movement can be effectively restricted.

In the manual locking device of the present invention, the locking unit can simultaneously lock the moving units respectively connected to the sliding double doors by the operating force of the operating unit.

Thereby, double-opening doors can be locked at the same time, and a state where one side is not locked can be avoided.

In the manual locking device of the present invention, the operation unit may be provided at the center of the double-opening door in the moving direction of the moving unit.

Thereby, double-opening doors can be locked at the same time, and operability can be improved.

In the manual locking device of the present invention, the transmission mechanism may have a connection moving part that moves integrally with the moving part.

Therefore, when the driving force is transmitted by any one of mechanisms such as a winding belt type, a rack and pinion type, a screw type, a linear motor type, and an electric cylinder as a transmission mechanism, these mechanisms and the moving part move integrally. It is possible to securely lock in any of the cases where the moving part and the door hanger move integrally.

In the manual locking device of the present invention, the operation unit may have an input unit for inputting an operation upward in the vertical direction.

Thereby, the operability of a locking operation can be improved.

In the manual locking device of the present invention, the operation unit may include a conversion unit that converts the operation force input vertically upward from the input unit into a lateral direction intersecting the moving direction of the moving unit.

Thereby, it can be attached to the upper position of the door of a landing, and space saving can be achieved. In addition, since the keyhole of the operation unit cannot be seen from the central position of the vehicle in the vehicle width direction, the design property can be improved.

The manual locking device of the present invention can be applied by appropriately selecting and combining the respective structures of the above-described embodiments. Furthermore, the respective configurations of the above-described embodiments can also be appropriately modified.

For example, an OoSL with a single door leaf can be used.

A structure in which the moving part 5 (the upper moving part 5 and the lower moving part 52 ) is not connected to the door hanger 11 is also possible. In this case, the moving part 5 (upper moving part 5 , lower moving part 52 ) can also be provided on the belt 42 at a position different from the position connected to the door hanger 11 .

The locking part 8 can also be a structure other than a link mechanism. In this case, it is possible to have a configuration for rotating the second arm 61c of the right restricting part 61 and the second arm 62c of the left restricting part 62 to approach the rotation shaft 81a at the same time to be in the locked position.
