Description

The present invention relates to a manual locking device and a railway door device, and to a technology suitable for use by train crew members to manually lock a door in a closed position so that it cannot be used when the door of a railway vehicle or the like breaks down.

For example, in the case of railway cars, in order to allow the train to continue traveling even if a malfunction occurs in the door, the door must be disabled. In such cases, a mechanism called OoSL (Out of Service Lock) is provided as a device that allows the train crew to manually lock the door in the closed position.

For example, in the case of a double-leaf sliding door, a configuration is known in which each door leaf is locked independently. As an example of this, Patent Document 1 describes a configuration in which the latch bar 7 moves into the latch hole 10 to lock the sliding door 1.

JP 2004-324159 A

However, in conventional technology, the mechanism locks the door by contacting the door leaf to restrict its movement, so the restriction occurs after the driving force is transmitted from the motor to the door leaf. As the movement of the heavy door leaf needs to be restricted, a large restricting force is required to stop the door from moving, which requires the restricting member to have great rigidity and strength, and the device tends to be strong and large, so there was a demand for a system that can lock with a smaller restricting force. Furthermore, there was a demand for a system that prevents a door leaf from becoming unlocked when one door leaf is locked in a double-leaf door.

The present invention aims to achieve the objective of providing an OoSL that can regulate with a small regulating force before the driving force is transmitted to the door leaf, compared to directly regulating the heavy door leaf.

As a means for solving the above problems, the present invention has the following configuration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a manual locking device and a railway door device according to the present invention will be described with reference to the drawings.
Fig. 1 is a schematic diagram of the vicinity of the boarding/alighting door of a railway vehicle in this embodiment as viewed in the vehicle width direction. Fig. 2 is a front view showing the open state of the railway door device and the manual locking device in this embodiment. Fig. 3 is a perspective view showing the vicinity of the locking part of the manual locking device in this embodiment. Fig. 4 is a perspective view showing the vicinity of the locking part of the manual locking device in this embodiment. In the figures, reference numeral 100 denotes a railway door device.

In the following embodiment, an example of a railway door device equipped with a pair of doors that open and close the boarding and alighting entrance of a railway car (vehicle) is described. Note that in the following description, expressions indicating relative or absolute arrangements, such as "parallel," "orthogonal," "center," and "coaxial," do not only mean such an arrangement strictly, but also include a state in which there is a relative displacement with a tolerance or an angle or distance that provides the same function. Note that in the drawings used in the following description, the scale of each component has been appropriately changed to make each component large enough to be recognized.

As shown in FIG. 1 , a railway door device 100 according to this embodiment is disposed above a boarding/alighting entrance 200 .
The railway door system 100 includes a manual locking system 101 .
2 to 4, the railway door device 100 includes a pair of doors 2, a drive source 3, a transmission mechanism 4, a moving unit 5, a restricting unit 6, an operating unit 7, a locking unit 8, and a lock restricting unit 9. The transmission mechanism 4, the moving unit 5, the restricting unit 6, the operating unit 7, the locking unit 8, and the lock restricting unit 9 configure a manual locking device 101.

In the following explanation, a Y, X, Z Cartesian coordinate system will be used as necessary. 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 indicates the height direction of the vehicle (direction of gravity) perpendicular to the Y and X directions. In the following explanation, the Y, X, and Z directions will be explained with the arrows in the figures as the plus (+) side and the opposite side to the arrows as the minus (-) side. The +Y side corresponds to the inside in the vehicle width direction, and the -Y side corresponds to the outside in the vehicle width direction. 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 railway door device 100 has a double-leaf door 2 that opens and closes the boarding/alighting entrance 200 by sliding in the X direction. As shown in FIG. 2, the door 2 has a door leaf 10 and a door hanger (connected moving part) 11 connected to the door leaf 10. The door 2 has an opening/closing path for opening and closing the boarding/alighting entrance 200 of the vehicle defined by a guide rail (not shown). The door leaf 10 moves back and forth in the X direction between a fully closed position and a fully open 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, the driving source 3 is a motor. The output shaft of the motor rotates around an axis along the front-rear direction. For example, the output shaft of the motor is rotatable in one direction and the other around an axis along the front-rear direction (forward and reverse rotation possible). The forward and reverse rotation of the motor moves the door leaf 10 back and forth in the X direction between a fully closed position and a fully open position.

The transmission mechanism 4 transmits the driving force from the driving source 3 to the door leaf 10 to move the door leaf 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 driving source 3, and an endless belt 42 that extends along the front-rear direction (X direction). The power conversion mechanism 41 converts the rotation of the motor output shaft about an axis along the front-rear direction to rotation about an axis along the vehicle width direction. The power conversion mechanism 41 includes a gear 43 that rotates about an axis along the vehicle width direction (Y direction). A pulley 44 that can rotate about an axis (axis along the Y direction) parallel to the rotation axis of the gear 43 is provided at a position spaced from the gear 43 in the front-rear direction.

The belt 42 is stretched across the gear 43 and pulley 44. The belt 42 moves (circulates) around the gear 43 and pulley 44 in conjunction with the rotation of the gear 43. The belt 42 is fitted with a moving part 5 that moves together with the movement of the belt 42. The moving part 5 moves back and forth in the front-rear direction (X direction). The 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 unit 5 reciprocates in the front-rear direction (X direction) between a fully closed corresponding position and a fully open corresponding position in response to the movement of the door leaf 10 between the fully closed position and the fully open position. The moving unit 5 is attached to the outside of the belt 42 that is stretched between the gear 43 and the pulley 44. Here, the outside of the belt 42 refers to the inside of a position surrounded by the belt 42 and close to the gear 43 and the pulley 44, and the outside of a position on the opposite side of the belt 42 from the gear 43 and the pulley 44, as viewed in the Y direction.
The fully closed corresponding position of the moving part 5 is located between the gear 43 and the pulley 44 in the front-rear direction (X direction).
As shown in FIG. 2 , the moving section 5 has an upper moving section 51 attached to the upper side of the belt 42 and a lower moving section 52 attached to the lower side of the belt 42 .

In FIG. 2, the right side position of the upper moving portion 51 adjacent to the pulley 44 in the front-rear direction (X direction) corresponds to a fully closed position, and the left side position adjacent to the gear 43 corresponds to a fully open position.
2, the lower moving part 52 has a fully open position on the right side in the front-rear direction (X direction) close to the pulley 44, and a fully closed position on the left side close to 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 section 51 and the lower moving section 52 move in opposite directions and by the same distance in accordance with the movement of the belt 42 in the front-to-rear direction (X direction). Therefore, the fully closed corresponding position of the upper moving section 51 and the fully closed corresponding position of the lower moving section 52 can be equidistant in the front-to-rear direction (X direction) with respect to the center of the boarding/alighting entrance 200. Similarly, the fully open corresponding position of the upper moving section 51 and the fully open corresponding position of the lower moving section 52 can be equidistant in the front-to-rear direction (X direction) with respect to the center of the boarding/alighting entrance 200.
Both the upper moving portion 51 and the lower moving portion 52 have a rectangular outer diameter when viewed in the vehicle width direction (Y direction).

The restricting portion 6 has a right restricting portion 61 and a left restricting portion 62 corresponding to the upper moving portion 51 and the lower moving portion 52. Note that the terms right and left are designated for convenience according to their positions in FIG.
The right restricting portion 61 is rotatably supported by a rotating shaft 61a having a rotation axis extending in the Y direction. The right restricting portion 61 is rotatably movable around the rotating shaft 61a between a locked position in which it contacts the upper moving portion 51 and an unlocked position in which it does not contact the upper moving portion 51 and does not hinder the movement of the upper moving portion 51.
The rotating shaft 61a is disposed at a position adjacent to the upper moving part 51 in the fully closed corresponding position. The rotating shaft 61a is disposed at a position adjacent to the upper moving part 51 in the −Z direction and −X direction when viewed in the Y direction.

The right restriction portion 61 has a first arm 61b and a second arm 61c extending in opposite directions from a 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 Z direction. The right restricting portion 61 rotates about 90° clockwise around the rotation shaft 61a from the unlocked position shown in FIG. 2 to the locked position.

In the unlocked position, the first arm 61b is in a position extending from the rotation shaft 61a in the -X direction, and in the locked position, the first arm 61b is in a position extending from the rotation shaft 61a in the +Z direction.
The first arm 61b is positioned inside the belt 42 when viewed in the Y direction in the unlocked position, and rotates to a position outside the belt 42 in the locked position.

The first arm 61b has a movement restricting portion 61d that contacts the upper moving portion 51 in the locked position and prevents the upper moving portion 51 from moving in the -X direction. When the upper moving portion 51 is in the fully closed position, the movement restricting portion 61d contacts the front surface 51a of the upper moving portion 51 in the -X direction (see FIG. 7 described below). That is, when in the locked position, the movement restricting portion 61d is positioned on the outside of the belt 42, and is positioned away from the rotation shaft 61a by a distance that allows it to contact the front surface 51a of the upper moving portion 51 in the -X direction.

The movement restricting portion 61d is located on the upper surface of the first arm 61b facing the +Z direction in the unlocked position. The movement restricting portion 61d has a surface shape parallel to the front surface 51a of the upper moving portion 51 in the locked position so as to contact the front surface 51a of the upper moving portion 51 over as large an area as possible. In other words, the movement restricting portion 61d has a surface along the YZ direction in the locked position.
When viewed in the Y direction, the rotation shaft 61a is disposed at a position closer in the -X direction than the front surface 51a of the upper moving part 51 that is in the fully closed corresponding position.

The first arm 61b is provided with a rotation shaft 61f at a position separated from the rotation shaft 61a and is connected to the locking unit 8 described below. The rotation shaft 61f has a rotation axis in the Y direction parallel to the rotation shaft 61a. The movement restricting unit 61d is located in the +Z direction from the rotation shaft 61f when the first arm 61b is in the unlocked position. In the right restricting unit 61, the rotation shaft 61f when in the locked position is located in the +Z direction from the rotation shaft 61a.

Similarly, the second arm 61c is in a position extending in the +X direction from the rotation shaft 61a in the unlocked position, and in a position extending in the -Z direction from the rotation shaft 61a in the locked position.
The second arm 61c is located inside the belt 42 when viewed in the Y direction in the unlocked position, and rotates to a position where it does not contact or interfere with the belt 42 in the locked position.

The second arm 61c has an engaged portion 61e that comes into contact with the locking restriction portion 9 (described later) in the unlocked position, preventing the right restriction portion 61 from rotating clockwise relative to the rotation shaft 61a. When the engaged portion 61e comes into contact with the locking restriction portion 9, the right restriction portion 61 is restrained by the locking restriction portion 9 and prevented from rotating.

The left regulating portion 62 is provided point-symmetrically with respect to the right regulating portion 61. Specifically, when viewed in the Y direction, the left regulating portion 62 and the right regulating portion 61 are disposed 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 rotating shaft 62a having a rotation axis extending in the Y direction. The left restricting portion 62 is rotatably moved around the rotating shaft 62a between a locked position in which the left restricting portion 62 contacts the lower moving portion 52 and an unlocked position in which the left restricting portion 62 does not contact the lower moving portion 52 and does not hinder the movement of the lower moving portion 52.
The rotating shaft 62a is disposed at a position adjacent to the lower moving part 52 in the fully closed corresponding position. The rotating shaft 62a is disposed at a position adjacent to the lower moving part 52 in the +Z direction and +X direction when viewed in the Y direction.

The left restriction portion 62 has a first arm 62b and a second arm 62c extending in opposite directions from a rotation shaft 62a.
The left restricting portion 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 Z direction. The left restricting portion 62 rotates about 90° clockwise around the rotation shaft 62a from the unlocked position shown in FIG. 2 to the locked position.

In the unlocked position, the first arm 62b is in a position extending from the rotation shaft 62a in the +X direction, and in the locked position, the first arm 62b is in a position extending from the rotation shaft 62a in the +Z direction.
The first arm 62b is positioned inside the belt 42 when viewed in the Y direction in the unlocked position, and rotates to a position outside the belt 42 in the locked position.

The first arm 62b has a movement restricting portion 62d that contacts the lower moving portion 52 in the locked position and prevents the lower moving portion 52 from moving in the +X direction. When the lower moving portion 52 is in the fully closed position, the movement restricting portion 62d contacts the front surface 52a of the lower moving portion 52 in the +X direction (see FIG. 7 described below). That is, the movement restricting portion 62d is located on the outside of the belt 42 in the locked position, and is positioned away from the rotation shaft 62a by a distance that allows it to contact the front surface 52a of the lower moving portion 52 in the +X direction.

The movement restricting portion 62d is located on the lower surface of the first arm 62b facing the -Z direction in the unlocked position. The movement restricting portion 62d has a surface shape parallel to the front surface 52a of the lower moving portion 52 in the locked position so as to contact the front surface 52a of the lower moving portion 52 over as large an area as possible. In other words, the movement restricting portion 62d has a surface along the YZ direction in the locked position.
When viewed in the Y direction, the rotation shaft 62a is disposed at a position closer in the +X direction than the front surface 52a of the lower moving part 52 which is in the fully closed corresponding position.

The first arm 62b is provided with a rotation shaft 62f at a position spaced apart from the rotation shaft 62a and is connected to the locking unit 8 described below. The rotation shaft 62f has a rotation axis in the Y direction parallel to the rotation shaft 62a. The movement restricting unit 62d is located in the -Z direction relative to the rotation shaft 62f when the first arm 62b is in the unlocked position. In the left restricting unit 62, the rotation shaft 62f when in the locked position is located in the -Z direction relative to the rotation shaft 62a.

Similarly, the second arm 62c extends in the −X direction from the rotation shaft 62a in the unlocked position, and extends in the +Z direction from the rotation shaft 62a in the locked position.
The second arm 62c is located inside the belt 42 when viewed in the Y direction in the unlocked position, and rotates to a position where it does not contact or interfere with the belt 42 in the locked position.

The second arm 62c has an engaged portion 62e that comes into contact with the locking restriction portion 9 (described later) in the unlocked position, preventing the left restriction portion 62 from rotating clockwise around the rotation shaft 62a. When the engaged portion 62e comes into contact with the locking restriction portion 9, the left restriction portion 62 is restrained by the locking restriction portion 9 and prevented from rotating.

The operating unit 7 generates an operating force for operating the locking unit 8 by being manually operated.
As shown in Figures 3 and 4, the operation unit 7 has an input unit 71 for manually inputting an operating force, and a conversion unit 72 for converting the direction of the operating force input from the input unit 71 and transmitting it to the locking unit 8.

The input portion 71 is disposed in the center of the entrance 200 in the X direction (see FIG. 1 ). The input portion 71 is located above the door leaf 10. The input portion 71 has an input shaft 71a that is rotated by engaging with a locking key (not shown).
The input shaft 71a has a rotation axis along the Z direction, and receives an operating force vertically upward from its lower end. The input shaft 71a is disposed equidistantly 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 disposed at the center of the boarding/alighting entrance 200 in the X direction.

The conversion unit 72 has bevel gears 71b, 72b that transmit rotation between the input shaft 71a and a rotating shaft 81a of the locking unit 8 described below and change the direction of transmission. The bevel gear 71b is arranged near the upper end of the input shaft 71a. The bevel gear 72b is arranged on the rotating shaft 81a of the locking unit 8 described below. The rotating shaft 81a has a rotation axis along the Y direction. The bevel gears 71b and 72b mesh with each other and transmit rotation from the input shaft 71a to the rotating shaft 81a.

As shown in Figures 2 to 4, the locking unit 8 has a first link 81 that rotates around a rotation axis 81a, a right second link (second link) 82 having one end connected to an end of the first link 81, and a left second link (second link) 83.
The rotating shaft 81a has a rotation axis along the Y direction. The rotating shaft 81a is disposed at the center position of the boarding/alighting entrance 200 in the X direction. The rotating shaft 81a is disposed equidistantly from the rotation axis of the gear 43 and the rotation axis of the pulley 44 in the X direction. The rotating shaft 81a is disposed on the inner side of the belt 42 when viewed in the Y direction.

In the unlocked position, the first link 81 has an arm 81b that extends in the +X direction with the rotation shaft 81a as the center position, and an arm 81c that extends in the -X direction.
The first link 81 can rotate 180° around the rotation axis 81a between an unlocked position in which the arms 81b and 81c extend in opposite directions along the X direction with the rotation axis 81a as the center position, and a locked position in which the arms 81b and 81c extend along the X direction but in the opposite direction to the unlocked position.

One end of the left second link (second link) 83 is connected to the tip of the arm 81c via a rotating shaft 81d. One end of the right second link (second link) 82 is connected to the tip of the arm 81c via a rotating shaft 81e. A stop portion 81g is formed at the tip of the arm 81c at a position farther away from the rotating shaft 81a than the rotating shaft 81e. The stop portion 81g stops the first link 81 in the locked position to restrict the rotational position. The stop portion 81g is restricted in position by contacting a stop restricting portion 84 in the locked position.

The arm 81b has a switch pressing portion 81g at its tip that contacts the lock switch 103. The switch pressing portion 81g can also serve as the stop portion 81g. When the switch pressing portion 81g contacts and turns ON the lock switch 103, the lock switch 103 detects that the first link 81 is in the locked position. In other words, the lock switch 103 detects that the moving portion 5 is in the fully closed position and that the restricting portion 6 is in the locked position.
This allows the lock switch 103 to be used as a switch for detecting whether the door is fully closed during normal vehicle operation.

In the unlocked position, the rotation shaft 81d is located away from the rotation shaft 81a in the +X direction. In the unlocked position, the rotation shaft 81e is located away from the rotation shaft 81a in the -X direction. When viewed in the Y direction, the distance between the rotation shaft 81d and the rotation shaft 81a is equal to the distance between the rotation shaft 81e and the rotation shaft 81a.

The left restricting portion 62 is rotatably connected to the other end of the left second link (second link) 83 via a rotation shaft 62f. The left second link (second link) 83 extends in the −X direction from the rotation shaft 81d in the unlocked position.
The right restricting portion 61 is rotatably connected to the other end of the right second link (second link) 82 via a rotation shaft 61f. In the unlocked position, the right second link (second link) 82 extends in the +X direction from the rotation shaft 81e.

In the unlocked position, the arm 81b extends from the rotation axis 81a in the +X direction, and the left second link (second link) 83 extends from the rotation axis 81d in the -X direction. Also, in the unlocked position, the arm 81b and the left second link (second link) 83 are parallel and overlap when viewed in the Y direction. For this reason, the left second link (second link) 83 has a curved portion 83a formed in a position close to the rotation axis 81d that curves in the -Z direction from the rotation axis 81d to avoid the rotation axis 81e.

In the unlocked position, the arm 81c extends from the rotation shaft 81a in the -X direction, and the right second link (second link) 82 extends from the rotation shaft 81e in the +X direction. In addition, in the unlocked position, the arm 81c and the right second link (second link) 82 are parallel and overlap when viewed in the Y direction. For this reason, the right second link (second link) 82 has a curved portion 82a formed in a position close to the rotation shaft 81e that curves in the +Z direction from the rotation shaft 81e to avoid the rotation shaft 81d.

The rotation shaft 81a, the rotation shaft 81d, the rotation shaft 81e, the rotation shaft 61f, and the rotation shaft 62f all extend along the Y direction and are parallel to one another.
The arm 81b, the left second link (second link) 83, and the left regulating portion 62 form a lock link that regulates movement of the lower moving portion 52 in the fully closed corresponding position.
The arm 81c, the right second link (second link) 82, and the right regulating portion 61 form a lock link that regulates movement of the upper moving portion 51 in the fully closed position.

Due to the operating force input from the operating unit 7, the first link 81 rotates clockwise as shown in FIG. 2 and hits the stop restricting unit 84, and the locking unit 8 is in the locked position. In this locked position, the first link 81 is in a horizontal position, that is, the arm 81b is in the -X direction and the arm 81c is in the -Y direction around the rotation axis 81a. At this time, as shown in FIG. 7 described later, the right second link 82 has the rotation axis 61f located above the rotation axis 81d in the Z direction. Similarly, the left second link 83 has the rotation axis 62f located below the rotation axis 81e in the Z direction. In other words, in the rotation from the unlocked position to the locked position, the first link 81 and the second links 82 and 83 rotate further beyond the dead center state where they are aligned in a straight line. In other words, when returning from the locked position to the unlocked position, the first link 81 and the second links 82 and 83 need to rotate again beyond the dead center.
When the first link 81 rotates counterclockwise as shown in FIG. 2 and assumes a horizontal position due to the operating force input from the operating unit 7, the locking unit 8 assumes the unlocked position.

The locking restriction section 9 enables the locking section 8 to lock the door only when the door leaf 10 is in the fully closed position.
As shown in FIGS. 2 to 4, the lock restriction portion 9 has a right lock restriction portion 91 and a left lock restriction portion 92.

The right locking restriction part 91 enables locking restriction for the right restriction part 61. The right locking restriction part 91 is rotatably supported by a rotation shaft 91a having a rotation axis extending in the Y direction. The right locking restriction part 91 is rotatable around the rotation shaft 91a between a lockable position where the right locking restriction part 91 is in contact with the upper moving part 51 and pressed against the upper moving part 51, and an unlockable position where the right locking restriction part 91 is not in contact with the upper moving part 51 or is not pressed against the upper moving part 51.
The rotation shaft 91a is disposed on the inside of the belt 42 when viewed in the Y direction. The rotation shaft 91a is disposed in a position close to the upper moving part 51 when it is in the fully closed corresponding position. The rotation shaft 91a is disposed in a position close to the upper moving part 51 in the -Z direction when it is in the fully closed corresponding position and coincident with the X direction when viewed in the Y direction. A torsion spring (not shown) is attached around the rotation shaft 91a to bias the right locking restriction part 91 counterclockwise around the rotation shaft 91a in FIG. 2.

The right locking restriction portion 91 is a cam having a first arm 91b extending in the +Z direction from a rotation shaft 91a, and an engagement portion 91h protruding in the -X direction from the base end side of the first arm 91b.
The first arm 91b has a pressed portion 91d at its tip which is pressed against the upper moving portion 51 by contacting the upper moving portion 51. The pressed portion 91d is formed at the tip of the first arm 91b extending in the +Z direction from the rotation shaft 91a and protruding in the -X direction. When the pressed portion 91d is pressed in the +X direction, the first arm 91b can rotate around the rotation shaft 91a from the non-lockable position to the lockable position. The pressed portion 91d is pressed by contacting the front surface 51b which faces forward when the upper moving portion 51 advances in the +X direction. When the pressure from the upper moving portion 51 is removed and the front surface 51b is not in contact with the pressed portion 91d, the first arm 91b returns from the lockable position to the non-lockable position by the torsion spring around the rotation shaft 91a.

The right locking restriction part 91 can rotate about a rotation shaft 91a between an unlocked position where the tip of the first arm 91b extends in the +Z direction and a lockable position where the tip of the first arm 91b is tilted in the +X direction compared to the unlocked position. The right locking restriction part 91 rotates clockwise around the rotation shaft 91a from the unlocked position shown in Fig. 2 to the lockable position (see Figs. 5 to 7 described later).
The engaging portion 91h in the unlocked position comes into contact with the engaged portion 61e to prevent rotational movement of the right restricting portion 61. The engaging portion 91h in the lockable position is separated from the engaged portion 61e and does not prevent movement of the right restricting portion 61.

In the right locking restriction part 91, the first arm 91b rotates to a lockable position when the upper moving part 51 presses against the pressed part 91d, and the contact between the engaging part 91h and the engaged part 61e is released, allowing the right restriction part 61 to lock.

The left lock regulating portion 92 is provided point-symmetrically with respect to the right lock regulating portion 91. Specifically, when viewed in the Y direction, the left lock regulating portion 92 and the right lock regulating portion 91 are disposed 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 locking restriction part 92 enables locking restriction for the left restriction part 62. The left locking restriction part 92 is rotatably supported by a rotation shaft 92a having a rotation axis extending in the Y direction. The left locking restriction part 92 is rotatable around the rotation shaft 92a between a lockable position where the left locking restriction part 92 is in contact with the lower moving part 52 and pressed against the lower moving part 52, and an unlockable position where the left locking restriction part 92 is not in contact with the lower moving part 52 or is not pressed against the lower moving part 52.

The rotating shaft 92a is positioned on the inside of the belt 42 when viewed in the Y direction. The rotating shaft 92a is positioned close to the lower moving part 52 when it is in the fully closed corresponding position. When viewed in the Y direction, the rotating shaft 92a is positioned close to the lower moving part 52 when it is in the fully closed corresponding position in the +Z direction and aligned in the X direction. A torsion spring (not shown) is attached around the rotating shaft 92a to bias the left locking restriction part 92 counterclockwise around the rotating shaft 92a in FIG. 2.

The left locking restriction portion 92 is a cam having a first arm 92b extending in the -Z direction from the rotation shaft 92a, a second arm 92c extending in the +Z direction from the rotation shaft 92a, and an engagement portion 92h protruding in the +X direction from the base end side of the first arm 92b.
The first arm 92b has a pressed portion 92d at its tip position which comes into contact with and is pressed by the lower moving portion 52. The pressed portion 92d is formed to protrude in the +X direction at the tip of the first arm 92b which extends 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 around the rotation shaft 92a from the non-lockable position to the lockable position. The pressed portion 92d comes into contact with the front surface 52b, which faces forward, and is pressed when the lower moving portion 52 moves in the -X direction. When the pressure from the lower moving portion 52 is removed and the front surface 52b is no longer in contact with the pressed portion 92d, the torsion spring around the rotation shaft 92a causes the first arm 92b to return from the lockable position to the non-lockable position.

The second arm 92c has a switch pressing portion 92e at its tip that contacts the full-close switch 102. When the switch pressing portion 92e comes into contact with the full-close switch 102 and turns ON, the full-close switch 102 detects that the lower moving portion 52 is in the fully-closed position and that the left locking restriction portion 92 is in the lockable position. In other words, the full-close switch 102 detects that the moving portion 52 is in the fully-closed position and that the locking restriction portion 92 is in the lockable position.

The left locking restriction part 92 can rotate about a rotation shaft 92a between an unlocked position where the tip of the first arm 92b extends in the -Z direction and a lockable position where the tip of the first arm 92b is inclined in the -X direction compared to the unlocked position. The left locking restriction part 92 rotates clockwise around the rotation shaft 92a from the unlocked position shown in Figure 2 to the lockable position (see Figures 5 to 7 described later).
The engaging portion 92h in the unlocked position comes into contact with the engaged portion 62e to prevent rotational movement of the left restricting portion 62. The engaging portion 92h in the lockable position is separated from the engaged portion 62e and does not prevent movement of the left restricting portion 62.

In the left locking restriction portion 92, when the lower moving portion 52 presses against the pressed portion 92d, the first arm 92b rotates to a lockable position, and the contact between the engaging portion 92h and the engaged portion 62e is released, making it possible to lock by the left restriction portion 62.
At the same time, the second arm 92c rotates integrally with the first arm 92b, and due to contact with the switch pressing portion 92e, it is detected that the full-close switch 102 is in the fully-close corresponding position, and an output is issued.
The fully closed switch 102 is connected to an interlock circuit which transmits a fully closed signal when all the doors 2 are fully closed, and when the doors are locked by the locking unit 8, the fully closed switch 103 is connected so as to bypass the interlock circuit and be able to transmit the fully closed signal at all times.

In the railway door device 100 of this embodiment, when the door 2 shown in FIG. 2 is open, or at least not fully closed, the moving part 5 is not in contact with the locking restriction part 9, so the locking restriction part 9 maintains the unlocked position and the restriction of the operation of the restriction part 6 by the locking restriction part 9 is maintained. Therefore, because the restriction part 6 maintains the unlocked position, manual locking is restricted.

Furthermore, when the door 2 is closed as shown in FIG. 5, that is, when the door leaf 10 has reached the fully closed position, the moving part 5 comes into contact with the locking restriction part 9, and the locking restriction part 9 is in a lockable position. This releases the restriction on the operation of the restriction part 6 by the locking restriction part 9. At the same time, the fully closed switch 102 detects that the door leaf 10 has reached the fully closed position.

Here, when manually locking the door 2, it is necessary that the door 2 can be locked only when the door leaf 10 has reached the fully closed position.
In this state, when locking from the operation unit 7, the input shaft 71a is rotated using a key (not shown). This operating force is transmitted to the bevel gear 71b, the bevel gear 72b, and the rotating shaft 81a, and the first link 81 of the locking unit 8 rotates.

When the door leaf 10 is in the fully closed position and the door is locked using the operation unit 7,
The first link 81 of the locking unit 8 rotates from the unlocked position shown in Fig. 2 to Fig. 5, through the intermediate state shown in Fig. 6, to the locked position shown in Fig. 7. The stop portion 81g hits the stop restricting portion 84, and the rotation stops at the locked position. As the first link 81 rotates, the second links 82, 83 and the right and left restricting portions 61 and 62 also rotate in conjunction with each other. As a result, in the locked position, as shown in Fig. 7, the second links 82, 83 are positioned such that the rotation axes 61f, 62f at the restricting portion 6 side end are farther apart in the Z direction than the rotation axes 81d, 81e at the first link 81 side end, relative to the first link 81 facing in the horizontal direction (X direction).

In other words, as shown in FIG. 7, the right second link 82 is in the locked position when it is rotated around the rotation axis 81d by an angle θ2, which is more than 180°, relative to the first link 81. Also, the left second link 83 is in the locked position when it is rotated around the rotation axis 81e by an angle θ3, which is more than 180°, relative to the first link 81.

The right second link 82 is inclined upward from the horizontal direction by an angle θ2 around the rotation axis 81d relative to the first link 81. This is because the right regulating part 61 has rotated to the locked position where the rotation axis 61f of the right regulating part 61 is located outside the belt 42 and the rotation axis 61f is located in the +Z direction relative to the rotation axis 61a.

Here, the left second link 83 is inclined downward from the horizontal direction by an angle θ3 around the rotation axis 81e with respect to the first link 81. This is because the left regulating part 62 has rotated to the locked position where the rotation axis 62f of the left regulating part 62 is located outside the belt 42 and the rotation axis 62f is located in the -Z direction with respect to the rotation axis 62a.
Here, when the door 2 is in the locked position and an attempt is made to open the door 2, the moving portion 5 attempts to move from the fully closed corresponding position. In this case, the moving portion 5 attempts to move toward the fully open corresponding position.

Then, in the right restricting section 61, the movement restricting section 61d is pressed in the -X direction from the front surface 51a of the upper moving section 51. Then, a force acts on the right restricting section 61 to rotate counterclockwise around the rotation axis 61a when viewed in the -Y direction. This force is transmitted to the second link 82 of the locking section 8, but at this time, it acts along the axis of the second link 82 and is transmitted from the rotation axis 81d 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 point relative to the first link 81, so the line of action of the force that attempts to open the door 2 and is transmitted from the right second link 82 to the first link 81 is directed in the direction of rotation to lock, and the rotation of the first link 81 is restricted by the stop restriction part 84.

Similarly, in the left restricting part 62, the movement restricting part 62d is pressed in the +X direction from the front surface 52a of the lower moving part 52. When this is done, a force acts on the left restricting part 62 to rotate counterclockwise around the rotation axis 61a when viewed in the -Y direction. This force is transmitted to the second link 83 of the locking part 8, but at this time, it acts along the axis of the second link 83 and is transmitted from the rotation axis 81e 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 point relative to the first link 81, so the line of action of the force attempting to open the door 2, which is transmitted from the left second link 83 to the first link 81, is directed in the rotational direction for locking, and the rotation of the first link 81 is restricted by the stop restricting portion 84.
In other words, unless the second links 82, 83 are rotated beyond the dead point, they cannot be rotated in the unlocking direction.
Therefore, it is possible to maintain the manually locked state without adding any other configuration.

Moreover, since the locked state is maintained in a state where the first link 81, the second link 82, and the second link 83 are point-symmetrical with respect to the rotation axis 81a when viewed in the Y direction after passing this dead point, it is possible to easily maintain the locked state even if the pressing force of the moving part 5 or the pressing force of the restricting part 6 in the unlocking direction is large.

In the railway door device 100 of this embodiment, the manual locking device 101 simultaneously locks the upper moving part 51 and the lower moving part 52 of the moving part 5 attached to the belt 42 of the transmission mechanism 4 that moves integrally with the door leaf 10 with the right regulating part 61 and the left regulating part 62 of the regulating part 6, respectively, to prevent the door leaf 10 from opening or closing. This makes it possible to lock the door with a smaller restricting force than when the door leaf is locked directly.

In the railway door device 100 of this embodiment, when the door is manually locked, the lock restricting portion 9 of the manual locking device 101 comes into contact with the restricting portion 6 to restrict the locking operation. The lock restricting portion 9 does not separate from the restricting portion 6 unless the door leaf 10 is in the fully closed position, that is, in the fully closed state. Therefore, when the door leaf 10 is not in the fully closed position, manual locking can be restricted.
Moreover, both of the door leaves 10 can be locked simultaneously by operating the keys of the operating section 9, and this locked state can be maintained.

This allows the door to be locked in a fully closed state even manually, reliably in cases where the door cannot be driven to close, such as when the vehicle needs to continue to travel in an emergency such as when the door 2 breaks down. In particular, compared to a mechanism that directly locks the door leaf 10, locking can be performed reliably even if the door leaf 10 is damaged, improving safety.

In addition, the door leaf 10 cannot be locked in any position other than the fully closed position, preventing malfunction and improving safety. Compared to mechanisms that directly lock the door leaf 10, the locking can be performed reliably with smaller parts and less restricting force.

With the above configuration, the locking restriction part 9 comes into contact with the moving part 5 and moves from the locking restriction position to the non-locking restriction position, enabling the restriction part 6 and the locking part 8 to be locked. Therefore, there is no need to provide a locking restriction part (blocking plate) over the entire range of the opening and closing direction, and manual locking is possible only in the fully closed position.

The manual locking device of the present invention may include a lock restriction section that allows locking by the locking section only when the door leaf is in the fully closed position.
This improves safety because the door cannot be locked unless the door leaf is fully closed.

In the manual locking device of the present invention, the restricting portion has an engaged portion,
The lock regulation unit is
an engaging portion that comes into contact with the engaged portion to prevent movement of the restricting portion;
a pressed portion that is pressed in a closing direction by the moving portion when the door leaf reaches a fully closed position, and that is capable of releasing contact between the engaging portion and the engaged portion;
It is possible to provide the following.
This makes it possible to switch between unlocking and locking simply by whether or not the moving part is pressing the pressed part, thereby reducing the number of electrical parts and improving operational reliability.

In the manual locking device of the present invention, the lock regulating portion is a cam including the pressed portion and the engaged portion,
When the pressed portion is pressed, the cam rotates to release the contact between the engaged portion and the engaging portion.
This makes it possible to reliably switch between contact and release between the engaged portion and the engaging portion.

The manual locking device of the present invention includes a full-close switch for detecting when the door leaf has reached the full-close position;
The cam may further include a switch pressing portion that rotates when the pressed portion is pressed, and presses the full-close switch.
This makes it possible to detect whether the door is in a fully closed state without directly detecting the position of the door leaf.

The manual locking device of the present invention is provided on a plurality of doors for opening and closing a plurality of boarding and alighting doors of a railway vehicle,
The fully closed switch can be connected to an interlock circuit which transmits a fully closed signal when all of the doors are fully closed, and when the locking unit is locked by manually operating the operating unit, the fully closed switch can be connected so as to bypass the interlock circuit and constantly transmit the fully closed signal.
This makes it possible to detect locking in an emergency when the door is manually locked, and also makes it possible to use the switch as a full-close switch for detecting full closure during normal door opening and closing.

In the manual locking device of the present invention, the locking unit includes a first link that rotates in response to an operating force of the operating unit;
a second link having one end connected to the end of the first link and the other end connected to the restricting portion,
The first link can rotate from the unlocked position toward the locked position, and the locked position can be reached at a position where the first link and the second link pass a dead point.
As a result, the first link and the second link are locked at a position where the angle between them exceeds the dead point, so that a structure for fixing the first link and the second link at the locked position is not necessary and the locking can be performed reliably.

In the manual locking device of the present invention, the second link can extend along the movement direction of the moving part at the locked position.
As a result, when the moving part tries to unlock the door while it is locked, it presses the second link in the direction in which it extends, making it easy to maintain the locked state even when a large force is applied.

In the manual locking device of the present invention, the regulating portion connected to the second link can contact a position toward the fully open corresponding position of the moving portion when the door leaf is positioned in the fully closed position.
As a result, the regulating portion directly contacts the point facing forward in the direction of movement from the fully closed position, which is the end of the range of movement of the moving portion, and regulates the moving portion, thereby effectively regulating movement.

In the manual locking device of the present invention, the locking section can simultaneously lock the moving sections connected to the respective sliding double-opening door leaves by the operating force of the operating section.
Both door leaves can be locked simultaneously, preventing a situation where only one door is unlocked.

In the manual locking device of the present invention, the operation portion may be provided at the center of the door leaf of a double-opening door in the movement direction of the moving portion.
This allows both door leaves to be locked simultaneously, improving operability.

In the manual locking device of the present invention, the transmission mechanism may have a connecting moving part that moves integrally with the moving part.
This allows for reliable locking in either case when the driving force is transmitted by a transmission mechanism such as a winding belt type, rack and pinion type, screw type, linear motor type, electric cylinder, etc., and the moving part moves integrally with the transmission mechanism, or the moving part moves integrally with the door hanger.

In the manual locking device of the present invention, the operation portion may have an input portion to which an operation is input vertically upward.
This can improve the ease of locking operation.

In the manual locking device of the present invention, the operation unit may have a conversion unit that converts an operating force input vertically upward from the input unit into a lateral direction intersecting the movement direction of the movement unit.
This allows it to be installed above the entrance doors, saving space, and improves the design because the keyhole for the operation unit cannot be seen from the center of the vehicle in the width direction.

The manual locking device of the present invention can be applied by appropriately selecting and combining the individual configurations in the above-described embodiments.
Furthermore, the individual configurations in the above-described embodiments can be modified as appropriate.
For example, the OoSL may have a single door leaf.
A configuration in which the moving unit 5 (upper moving unit 5, lower moving unit 52) is not connected to the door hanger 11 is also possible. In this case, the moving unit 5 (upper moving unit 5, lower moving unit 52) can be provided on the belt 42 at a position different from the position where it is connected to the door hanger 11.
The locking unit 8 may be configured not to be a link mechanism. In this case, the second arm 61c of the right restricting unit 61 and the second arm 62c of the left restricting unit 62 may be configured to rotate toward the rotation shaft 81a at the same time to the locked position. Furthermore, in this case, a configuration may be provided to rotate them in the opposite direction to the locking direction to return them to their original positions.
