Description

The present invention relates to a manual locking device and a railroad door device, and relates to a technique suitable for use when a crew member or the like manually locks the door to a closed state so that the door cannot be used when a door for a railroad vehicle or the like breaks down. ..

For railroad cars and the like, it is necessary to make the doors unusable in order to be able to run even when, for example, a railroad car door has a problem. In this case, a mechanism called OoSL (Out of Service Lock) is provided as a device for the crew to manually lock the railroad vehicle door in the closed state.

For example, in the case of a double-door sliding door, it is known that each door leaf is independently locked. As such an example, Patent Document 1 describes a configuration in which the sliding door 1 is locked by moving the latch rod 7 to the latch hole 10.

However, in the conventional technology, since it is a mechanism that locks the door by restricting the movement by contacting with the door leaf, it is regulated after the driving force is transmitted from the motor to the door leaf, which is a heavy door leaf. Since it is necessary to regulate the movement, a large regulatory force is required to prevent the door from moving, a large rigidity and strength are required for the regulating member, and the device tends to be stronger and larger. Therefore, there was a demand to enable locking with less regulatory power. Furthermore, there was a request to prevent this from happening if one of the door leaves of the double doors is locked and the other door leaf is not locked.

It is an object of the present invention to provide an OoSL that can be regulated with a small regulatory force before the driving force is transmitted to the door leaf as compared with the case of directly regulating a heavy door leaf.

FIG. 3 is a perspective view showing the vicinity of the locked portion in the manual locking device according to the present embodiment. FIG. 4 is a perspective view showing the vicinity of the locked portion in the manual locking device according to the present embodiment. In the figure, reference numeral 100 is a railroad door device.

In the following embodiment, an example will be described in which a pair of double-drawn doors for opening and closing the entrance / exit of a railroad vehicle (vehicle) is provided as a railroad door device. In the following description, expressions indicating relative or absolute arrangements such as "parallel", "orthogonal", "center", and "coaxial" not only strictly mean such arrangements, but also. It also includes the state of relative displacement with tolerances and angles and distances to the extent that the same function can be obtained. In the drawings used in the following description, the scale of each member is appropriately changed in order to make each member recognizable.

As shown in FIG. 1, the railroad door device 100 according to the present embodiment is arranged above the entrance / exit 200.
The railroad door device 100 includes a manual locking device 101.
As shown in FIGS. 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 regulating unit 6, an operating unit 7, and a locking unit. It has 8 and a locking control unit 9. The transmission mechanism 4, the moving unit 5, the regulating unit 6, the operating unit 7, the locking unit 8, and the locking restricting unit 9 constitute a manual locking device 101.

In the following description, a Y, X, and Z orthogonal 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 (gravity direction) of the vehicle orthogonal to the Y direction and the X direction. In the following description, of the Y direction, the X direction, and the Z direction, the arrow side in the figure will be referred to as a plus (+) side, and the side opposite to the arrow will be referred to as a 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 railroad door device 100 has a double door 2 that slides the entrance / exit 200 in the X direction to open / close. As shown in FIG. 2, the door 2 includes a door leaf 10 and a door hanger (connecting moving portion) 11 connected to the door leaf 10. The door 2 is defined by an opening / closing route for opening / closing the entrance / exit 200 of the vehicle by a guide rail (not shown). The door leaf 10 reciprocates in the X direction between the fully closed position and the fully open position. The door 2 is opened and closed by the drive source 3.

The drive source 3 outputs a driving force for moving the door 2. For example, the drive 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 can rotate (forward and reverse rotation) on one side and the other side around the axis along the front-rear direction. The forward and reverse rotation of the motor causes the door leaf 10 to reciprocate in the X direction between the fully closed position and the fully open position.

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

The belt 42 is bridged between the gear 43 and the pulley 44. The belt 42 moves (circulates) around the gear 43 and the pulley 44 in conjunction with the rotation of the gear 43. A moving portion 5 that moves with the movement of the belt 42 is attached to the belt 42. The moving unit 5 reciprocates in the front-rear direction (X direction). A door hanger 11 is connected to the moving portion 5. The opening / 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 the fully closed position and the fully open position in response to the movement between the fully closed position and the fully open position of the door leaf 10. The moving portion 5 is attached to the outside of the belt 42 bridged between the gear 43 and the pulley 44. Here, the outside of the belt 42 is the inside, which is surrounded by the belt 42 and is close to the gear 43 and the pulley 44 when viewed in the Y direction, and is on the opposite side of the gear 43 and the pulley 44 with respect to the belt 42. The position is outside.

The door leaf 10 on the right side shown in FIG. 2 is connected to the lower moving portion 52 via the door hanger 11.

The upper moving portion 51 and the lower moving portion 52 move in opposite directions and by the same distance according to the movement of the belt 42 in the front-rear direction (X direction). Therefore, the fully closed position of the upper moving portion 51 and the fully closed corresponding position of the lower moving portion 52 can be equidistant in the front-rear direction (X direction) with respect to the center of the entrance / exit 200. Similarly, the fully open corresponding position of the upper moving portion 51 and the fully open corresponding position of the lower moving portion 52 can be equidistant in the front-rear direction (X direction) with respect to the center of the entrance / exit 200.

Further, at the unlocking position, the arm 81b and the left second link (second link) 83 are parallel to each other and overlap each other when viewed in the Y direction. Therefore, on the left second link (second link) 83, a curved portion 83a that curves in the −Z direction from the rotating shaft 81d and avoids the rotating shaft 81e is formed at a position close to the rotating shaft 81d.

At 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. Further, at the unlocking position, the arm 81c and the right second link (second link) 82 are parallel to each other and overlap each other in the Y direction. Therefore, on the right second link (second link) 82, a curved portion 82a that curves in the + Z direction from the rotating shaft 81e and avoids the rotating shaft 81d is formed at a position close to the rotating shaft 81e.

The rotation shaft 81a, the rotation shaft 81d, the rotation shaft 81e, the rotation shaft 61f, and the rotation shaft 62f are all along the Y direction and are parallel to each other.
The arm 81b, the left second link (second link) 83, and the left restricting portion 62 form a lock link that restricts movement with respect to the lower moving portion 52 at the fully closed position.
The arm 81c, the right second link (second link) 82, and the right restricting unit 61 form a lock link that restricts movement with respect to the upper moving unit 51 in a fully closed position.

Due to the operating force input from the operation unit 7, the first link 81 rotates clockwise as shown in FIG. 2 and hits the stop control unit 84, and the locking unit 8 becomes the locking position. In this locked position, the first link 81 is in a horizontal position, that is, a rotation position in which the arm 81b is along 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, which will be described later, in the right second link 82, the rotation shaft 61f is located above the rotation shaft 81d in the Z direction. Similarly, in the left second link 83, the rotation shaft 62f is located below the rotation shaft 81e in the Z direction. That is, in the rotation from the unlocked position to the locked position, the first link 81 and the second links 82, 83 are further rotated beyond the state of the dead center arranged in a straight line. That is, when returning from the locked position to the unlocked position, the first link 81 and the second links 82, 83 need to rotate beyond the dead center again.
When the first link 81 is rotated counterclockwise as shown in FIG. 2 to a horizontal position due to the operating force input from the operation unit 7, the locking unit 8 is in the unlocking position.

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

The right locking control unit 91 enables locking regulation for the right locking unit 61. The right lock control unit 91 is rotatably supported by a rotation shaft 91a having a rotation axis extending in the Y direction. The right locking control unit 91 has a lockable position that is in contact with the upper moving portion 51 and pressed against the upper moving portion 51, and a lockable position that the upper moving portion 51 does not contact or is not pressed against the upper moving portion 51. It is rotatable around the rotation shaft 91a between the two.
The rotation shaft 91a is arranged inside the belt 42 when viewed in the Y direction. The rotation shaft 91a is arranged at a position close to the upper moving portion 51 in the fully closed position. The rotation shaft 91a is arranged at a position close to the −Z direction and coincide with the X direction of the upper moving portion 51 in the fully closed position when viewed in the Y direction. A torsion spring (not shown) is attached around the rotating shaft 91a to urge the right locking restricting portion 91 counterclockwise around the rotating shaft 91a in FIG. 2.

The right locking control portion 91 is a cam having a first arm 91b extending in the + Z direction from the rotation shaft 91a and an engaging portion 91h protruding in the −X direction on the proximal end side of the first arm 91b.
The first arm 91b has a pressed portion 91d at the tip position, which is in contact with the upper moving portion 51 and is pressed by the upper moving portion 51. The pressed portion 91d is formed so as to project in the −X direction at 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 around the rotation shaft 91a from the lockable position to the lockable position. The pressed portion 91d is pressed in contact with the front surface 51b, which is forward facing when the upward moving portion 51 advances in the + X direction. When the pressure from the upward moving portion 51 is eliminated and the front surface 51b does not come into 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 rotating shaft 91a.

The right locking control unit 91 has a rotation axis between a lockable 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 lockable position. It is rotatable around 91a. The right lock control unit 91 rotates clockwise around the rotation shaft 91a from the lockable position shown in FIG. 2 to reach the lockable position (see FIGS. 5 to 7 described later).
The engaging portion 91h at the non-lockable position contacts the engaged portion 61e and hinders the rotational movement of the right regulating portion 61. The engaging portion 91h at the lockable position is separated from the engaged portion 61e and does not hinder the movement of the right regulating portion 61.

In the right lock control unit 91, the first arm 91b is rotated by the pressure from the upward moving unit 51 to the pressed portion 91d to be in a lockable position, and the contact between the engaging portion 91h and the engaged portion 61e is released. It can be locked by the right regulation unit 61.

The left lock control unit 92 is provided point-symmetrically with respect to the right lock control unit 91. Specifically, the left lock control unit 92 and the right lock control unit 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 when viewed in the Y direction.
The left lock control unit 92 enables lock control for the left control unit 62. The left lock control unit 92 is rotatably supported by a rotation shaft 92a having a rotation axis extending in the Y direction. The left lock control unit 92 has a lockable position that is in contact with the lower movement unit 52 and is pressed against the lower movement unit 52, and a lockable position that is not in contact with the lower movement unit 52 or is not pressed by the lower movement unit 52. It is rotatable around the rotation shaft 92a between the two.

The rotation shaft 92a is arranged inside the belt 42 when viewed in the Y direction. The rotation shaft 92a is arranged at a position close to the lower moving portion 52 at the fully closed position. The rotation shaft 92a is arranged at a position close to the + Z direction and coincident in the X direction of the lower moving portion 52 in the fully closed position when viewed in the Y direction. A torsion spring (not shown) is attached around the rotating shaft 92a to urge the left locking restricting portion 92 counterclockwise around the rotating shaft 92a in FIG.

The left locking control unit 92 projects in the + X direction at the base end side of the first arm 92b extending in the −Z direction from the rotation shaft 92a, the second arm 92c extending in the + Z direction from the rotation shaft 92a, and the first arm 92b. It is a cam having an engaging portion 92h and.
The first arm 92b has a pressed portion 92d at the tip position, which is in contact with the lower moving portion 52 and is pressed by the lower moving portion 52. The pressed portion 92d is formed so as to project in the + X direction at the tip 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 around the rotation shaft 92a from the lockable position to the lockable position. The pressed portion 92d is pressed in contact with the front surface 52b, which is facing forward when the downward moving portion 52 advances in the −X direction. When the pressing from the lower moving portion 52 is eliminated and the front surface 52b does not come into contact with the pressed portion 92d, the first arm 92b returns from the lockable position to the unlockable position by the torsion spring around the rotating shaft 92a.

The second arm 92c has a switch pressing portion 92e at its tip that contacts the fully closed switch 102. The fully closed switch 102, which is turned on by contact with the switch pressing portion 92e, detects that the lower moving portion 52 is in the fully closed position and the left lock restricting portion 92 is in the lockable position. That is, the fully closed switch 102 detects that the moving unit 5 is in the fully closed position and the lock restricting unit 9 is in the lockable position.

The left lock control unit 92 is between a lockable 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 tilted in the −X direction with respect to the lockless position. It is rotatable around the rotation shaft 92a. The left lock control unit 92 rotates clockwise around the rotation shaft 92a from the lockable position shown in FIG. 2 to reach the lockable position (see FIGS. 5 to 7 described later).
The engaging portion 92h in the non-lockable position contacts the engaged portion 62e and hinders the rotational movement of the left regulating portion 62. The engaging portion 92h at the lockable position is separated from the engaged portion 62e and does not hinder the movement of the left regulating portion 62.

In the left lock control unit 92, the first arm 92b is rotated by the pressure from the lower moving portion 52 to the pressed portion 92d to be in a lockable position, and the contact between the engaging portion 92h and the engaged portion 62e is released. It can be locked by the left regulation unit 62.
At the same time, the second arm 92c rotates integrally with the first arm 92b, and the fully closed switch 102 detects that the fully closed switch 102 is in the fully closed position by contact with the switch pressing portion 92e and outputs the output.
The fully closed switch 102 is connected to an interlock circuit that transmits a fully closed signal when all the doors 2 are fully closed, and when locked by the locking unit 8, the fully closed switch 103 closes the interlock circuit. Bypassing is connected so that the fully closed signal can always be transmitted.

In the railway door device 100 of the present embodiment, when the door 2 shown in FIG. 2 is open, at least not fully closed, the moving portion 5 is not in contact with the lock restricting portion 9, so that the lock restricting portion 9 cannot be locked. The position is maintained, and the operation regulation of the regulation unit 6 by the lock regulation unit 9 is maintained. Therefore, manual locking is restricted in order for the regulating unit 6 to maintain the unlocking position.

Further, when the door 2 shown in FIG. 5 is closed, that is, when the door leaf 10 reaches the fully closed position, the moving portion 5 abuts on the lock restricting portion 9, and the lock restricting portion 9 is in the lockable position. .. As a result, the operation regulation of the regulation unit 6 by the lock regulation unit 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 the door 2 is manually locked, it is necessary that the door leaf 10 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 by 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 portion 8 rotates.

When the door leaf 10 is in the fully closed position and the lock operation is performed from the operation unit 7.
The first link 81 of the locking portion 8 rotates from the unlocking position shown in FIGS. 2 to 5 to the locking position shown in FIG. 7 via the intermediate state shown in FIG. The stop portion 81g hits the stop regulation portion 84 and the rotation is stopped at the locked position. As the first link 81 rotates, the second links 82, 83, the right regulating unit 61, and the left regulating unit 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 the rotation shafts of the ends on the side of the first link 81 with respect to the first link 81 facing the horizontal direction (X direction). The rotation shafts 61f and 62f at the end of the regulation portion 6 are located farther from the first link 81 in the Z direction than the 81d and 81e.

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

Here, with respect to the first link 81, the right second link 82 is tilted upward by an angle θ2 around the rotation axis 81d. This is because the rotation shaft 61f of the right regulation portion 61 is located outside the belt 42, and the right regulation portion 61 is rotated to the locking position where the rotation shaft 61f is located in the + Z direction with respect to the rotation shaft 61a.

Here, with respect to the first link 81, the left second link 83 is tilted downward from the horizontal direction by an angle θ3 around the rotation axis 81e. This is because the rotation shaft 62f of the left regulation portion 62 is located on the outside of the belt 42, and the left regulation portion 62 is rotated to the locking position where the rotation shaft 62f is located in the −Z direction with respect to the rotation shaft 62a.
Here, when the door 2 tries to open in the locked position, the moving portion 5 tries to move from the fully closed position. In this case, the moving unit 5 tends to move toward the fully open position.

Then, in the right restricting portion 61, the movement restricting portion 61d is pressed in the −X direction from the front surface 51a of the upper moving portion 51. Then, the right regulating portion 61 is viewed in the −Y direction, and a force that tends to rotate counterclockwise around the rotation axis 61a acts on the right regulating portion 61. This force is transmitted to the second link 82 of the locking portion 8, but at this time, it acts along the axis of the second link 82 and is transmitted from the rotation shaft 81d to the first link 81.

As described above, in the locked position, since the right second link 82 is at an angle position beyond the dead center with respect to the first link 81, it is transmitted from the right second link 82 to the first link 81. The line of action of the force for opening the door 2 is directed in the direction of rotation for locking, and the rotation of the first link 81 is restricted by the stop restricting unit 84.

Similarly, in the left restricting portion 62, the movement restricting portion 62d is pressed in the + X direction from the front surface 52a of the lower moving portion 52. Then, the left regulating unit 62 is viewed in the −Y direction, and a force that tends to rotate counterclockwise around the rotation axis 61a acts on it. This force is transmitted to the second link 83 of the locking portion 8, but at this time, it acts along the axis of the second link 83 and is transmitted from the rotation shaft 81e to the first link 81.

As described above, in the locked position, since the left second link 83 is at an angle position beyond the dead center with respect to the first link 81, it is transmitted from the left second link 83 to the first link 81. The line of action of the force for opening the door 2 is directed in the direction of rotation for locking, and the rotation of the first link 81 is restricted by the stop restricting unit 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, it is possible to maintain the locked state manually without adding other configurations.

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

In the railroad door device 100 of the present embodiment, in the manual locking device 101, the upper moving portion 51 and the lower moving portion 52 of the moving portion 5 attached to the belt 42 of the transmission mechanism 4 that moves integrally with the door leaf 10 are simultaneously used. The door leaf 10 is not opened or closed by being locked by the right regulation unit 61 and the left regulation unit 62 of the regulation unit 6, respectively. As a result, it is possible to lock with a smaller regulatory force than when the door leaf is directly locked.

In the railroad door device 100 of the present embodiment, when the door device 100 is manually locked, the lock regulation unit 9 hits the regulation unit 6 in the manual lock device 101 and regulates the door device 100 so that the lock operation cannot be performed. The lock control unit 9 does not separate from the control unit 6 unless the door leaf 10 is in the fully closed position and is in the fully closed state. Therefore, when the door leaf 10 is not in the fully closed position, it can be regulated so that it cannot be locked manually.
Moreover, each of the double-door door leaves 10 can be locked at the same time by operating the key of the operation unit 9, and this locked state can be maintained.

As a result, when the door cannot be driven to close, for example, it is necessary to drive the vehicle even in an emergency such as when a failure occurs in the door 2, the operation of locking in the fully closed state can be reliably performed manually. .. In particular, as compared with the mechanism for directly locking the door leaf 10, even if the door leaf 10 is damaged, the lock can be reliably performed and the safety can be improved.

Further, since the door leaf 10 cannot be locked except in the fully closed position, malfunction can be prevented and safety can be improved. Compared to the mechanism that directly locks the door leaf 10, it is possible to securely lock the door leaf 10 with a small component and a small regulatory force.

According to the above configuration, the lock restricting unit 9 comes into contact with the moving unit 5 and moves from the locked restricted position to the unlocked restricted position, enabling the locking operation of the restricted unit 6 and the locked unit 8. Therefore, it is possible to manually lock the lock only in the fully closed position without providing the lock control portion (blocking plate) over the entire opening / closing direction.

The manual locking device of the present invention may include a locking restricting unit that enables locking by the locking unit only when the door leaf is located in the fully closed position.
As a result, safety can be improved because the door leaf cannot be locked unless it is fully closed.

The cam may further include a switch pressing portion that rotates when the pressed portion is pressed to press the fully closed switch.
This makes it possible to detect that the door leaf 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 entrances and exits of a railway vehicle.
When the fully closed switch is connected to an interlock circuit that transmits a fully closed signal when all the doors are fully closed, and when the lock is locked by manually operating the operation unit. , The fully closed switch can be connected so as to bypass the interlock circuit and always transmit the fully closed signal.
As a result, it is possible to detect the lock in an emergency when the door is locked by manual operation, and it is possible to use it as a fully closed switch for detecting the fully closed in the normal opening and closing of the door.

In the manual locking device of the present invention, the locking portion has a first link in which the locking portion is rotated by the operating force of the operating portion.
A second link is provided, one end of which is connected to the end of the first link and the other end of which is connected to the restricting portion.
The first link can be rotated 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 exceed the dead center.
As a result, since the angle between the first link and the second link is locked at a position beyond the dead center, there is no need for a configuration for fixing the first link and the second link at the locked position, and It can be locked securely.

In the manual locking device of the present invention, the second link can extend at the locking position along the moving direction of the moving portion.
As a result, when the moving portion tries to unlock the lock at the time of locking, the second link is pressed in the extending direction, and it becomes easy to maintain the locked state even if a large force is applied.

In the manual locking device of the present invention, the restricting portion connected to the second link can be in contact with the position of the moving portion toward the fully open position when the door leaf is located in the fully closed position. ..
As a result, the regulating unit directly contacts the position facing forward in the moving direction from the fully closed position, which is the end of the moving range of the moving portion, and regulates the moving portion, so that the movement can be effectively regulated. can.

In the manual locking device of the present invention, the locking portion can simultaneously lock the moving portion connected to each of the sliding double-door door leaves by the operating force of the operating portion.
Double-door door leaf can be locked at the same time, and it is possible to avoid the situation where only one is not locked.

In the manual locking device of the present invention, the operation unit can be provided in the center of the door leaf that opens on both sides in the moving direction of the moving unit.
As a result, the double-door door leaf can be locked at the same time, and the operability can be improved.

In the manual locking device of the present invention, the transmission mechanism can have a connecting moving portion that moves integrally with the moving portion.
As a result, when the driving force is transmitted by any of the winding belt type, rack and pinion type, screw type, linear motor type, electric cylinder, and other mechanisms as the transmission mechanism, these and the moving part move integrally. In any case, the moving part can be moved integrally with the door hanger, and the lock can be securely locked.

This makes it possible to improve the operability in the locking operation.

In the manual locking device of the present invention, the operation unit can have a conversion unit that converts an operating force vertically upwardly input from the input unit into a lateral direction intersecting the movement direction of the moving unit.
As a result, it can be incorporated in the position on the door of the entrance / exit, and space can be saved. Further, since the keyhole of the operation unit cannot be seen from the center position of the vehicle in the vehicle width direction, the design can be improved.

The manual locking device of the present invention can be applied by appropriately selecting and combining the individual configurations in the above-described embodiment.
Further, the individual configurations in the above-described embodiments can be changed as appropriate.
For example, the door leaf may be an OoSL having one sheet.
