Description

Manual locking device and door device for railway

Technical Field

The present invention relates to a manual locking device and a railway door device. More specifically, the present invention relates to a technique suitable for use in a case where a door for a railway vehicle or the like is locked in a closed state manually by a crew or the like when the door fails, or the like, so that the door cannot be used.

Background

In a railway vehicle or the like, it is necessary to make a door unusable in order to enable the vehicle to run even when a defect occurs in the door of the railway vehicle, for example. In this case, a mechanism called an OoSL (Out of Service Lock) is provided as a device for a crew to manually Lock the door of the railway vehicle in a closed state.

For example, in the case of a double-opening sliding door, a structure is known in which each door leaf on one side is independently locked. As an example of this, patent document 1 describes a structure in which the sliding door 1 is locked by moving the lock lever 7 to the lock hole 10.

Problems to be solved by the invention

However, the conventional technique is a mechanism as follows: the movement is restricted by contact with the door leaf, thereby locking the door. Therefore, since the door is regulated after the driving force is transmitted from the motor to the door, it is necessary to regulate the movement of the door having a weight. Therefore, a large restraining force is required to immobilize the door. Therefore, the restricting member requires high rigidity and strength, and the device tends to be high in strength and large in size.

However, there is a demand for enabling locking of the door with a smaller restraining force. In addition, in the double-opening sliding door, there is a demand that one door leaf is not locked when the other door leaf is locked.

An object of the present invention is to provide an OoSL that can restrict a door with a smaller restriction force before a driving force is transmitted to the door, as compared with a case where a heavy door is directly restricted.

Means for solving the problems

(1) The manual locking device according to an aspect of the present invention includes: a transmission mechanism that transmits a driving force from a driving source to a door to move the door between a fully open position and a fully closed position; a moving unit provided in the transfer mechanism and moving in synchronization with opening and closing of the door; a restricting portion that contacts the moving portion in an opening/closing direction of the door to restrict movement of the moving portion; an operation unit that generates an operation force by manual operation; and an upper lock portion that moves the restricting portion from an unlock position, at which the movement of the moving portion is not restricted, to a lock position, at which the movement of the moving portion is restricted, by an operating force of the operating portion when the door is located at the fully-closed position, and that locks the door.

According to the manual locking device of one aspect of the present invention, since the door is prevented from being opened and closed by locking the moving portion in the middle of the transmission mechanism that moves integrally with the door by the restricting portion, the manual locking device can be locked with a smaller restricting force than a case where the door is directly locked.

(2) The manual locking device may further include a locking restriction unit that allows the locking by the upper lock unit to be performed only when the door is located at the fully closed position.

(3) The restricting portion may have an engaged portion. The locking restriction unit may include: an engaging portion that is in contact with the engaged portion to interfere with movement of the restricting portion; and a pressed portion that is pressed in a closing direction by the moving portion when the door reaches the fully closed position, and that is capable of releasing contact between the engaging portion and the engaged portion.

(4) The lock restricting portion may be a cam including the pressed portion and the engaging portion, and the cam may be rotated by being pressed by the pressed portion to release the contact between the pressed portion and the engaging portion.

(5) The manual locking device may further include a full close switch for detecting that the door has reached the full close position. The cam may further include a switch pressing portion that is pressed by the pressed portion and rotates to press the full close switch.

(6) The manual locking device may be provided to a plurality of doors that open and close a plurality of entrance/exit ports of the railway vehicle. The full close switch may be connected to an interlock circuit that transmits a full close signal when all the doors are fully closed, and may be connected to transmit the full close signal all the time by bypassing the interlock circuit when the operating portion is manually operated to lock the doors by the upper lock portion.

(7) The locking unit may include: a 1 st link rotated by an operation force of the operation unit; and a 2 nd link having one end connected to an end of the 1 st link and the other end connected to the restricting portion. The 1 st link may be rotated from the unlock position toward the lock position, and the 1 st link and the 2 nd link may be set to the lock position at positions beyond a dead point.

(8) The 2 nd link may extend along a moving direction of the moving portion at the locked position.

(9) The restricting portion connected to the 2 nd link may be in contact with a position of the moving portion toward the fully open position when the door is located at the fully closed position.

(10) The locking unit may simultaneously lock the moving units connected to the sliding door leaves that are opened in two opposite directions by the operating force of the operating unit.

(11) The operation portion may be provided at the center of the door leaves that are opened in both directions in the moving direction of the moving portion.

(12) The transmission mechanism may have a coupling moving portion that moves integrally with the moving portion.

(13) The operation unit may have an input unit for inputting an operation in a vertical direction.

(14) The operation unit may include a conversion unit that converts an operation force input from the input unit in a vertical direction upward into a lateral direction that intersects a moving direction of the moving unit.

(15) A railway door device according to another aspect of the present invention includes: a door for opening and closing an entrance of a railway vehicle; a driving source that drives the door; a transmission mechanism that transmits a driving force from the driving source to the door to move the door between a fully open position and a fully closed position; a moving unit provided in the transfer mechanism and moving in synchronization with opening and closing of the door; a restricting unit that restricts movement of the moving unit in an opening/closing direction of the door; an operation unit that generates an operation force by manual operation; and an upper lock portion that moves the restricting portion from an unlock position that does not restrict movement of the moving portion to a lock position that restricts movement of the moving portion by an operating force of the operating portion when the door is at the fully closed position, thereby locking the door.

According to the railway door device according to the other aspect of the present invention, the door is not opened and closed by locking the moving portion in the middle of the transmission mechanism by the restricting portion while moving integrally with the door, and therefore, the door can be locked with a smaller restricting force than a case where the door is directly locked.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the present invention, the force transmission to the door is restricted by contact with the moving portion provided in the transmission mechanism for transmitting the driving force to the door. This makes it possible to restrict the movement of the door with a smaller force than in the case where the movement is restricted by contact with the door.

Detailed Description

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 view of the vicinity of an entrance of a railway vehicle in the present embodiment as viewed from the vehicle width direction. Fig. 2 is a front view showing an opened 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 denotes a railway door device.

In the following embodiments, an example including a pair of double-acting doors that open and close an entrance of a railway vehicle (vehicle) is described as a railway door device.

In the following description, terms indicating relative or absolute arrangement such as "parallel", "orthogonal", "central" and "coaxial" are not limited to the case of strictly indicating such arrangement. For example, the above-mentioned terms also include a state in which the components are relatively displaced by a tolerance, an angle to the extent that the same function can be obtained, and a distance. In the drawings used in the following description, the scale of each member is appropriately changed so that each member can be made into a recognizable size.

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

As shown in fig. 2 to 4, the railroad door device 100 includes a pair of doors 2, a drive source 3, a transmission mechanism 4, a moving portion 5, a restricting portion 6, an operating portion 7, an upper lock portion 8, and a locking restricting portion 9.

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

In the following description, an orthogonal coordinate system of Y, X, Z is 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 a height direction (gravity direction) of the vehicle orthogonal to the Y direction and the X direction.

In the following description, the arrow side in the figure is assumed to be the plus (+) side and the side opposite to the arrow is assumed to be the minus (-) side among the Y direction, the X direction, and the Z direction. The + Y side corresponds to the inside in the vehicle width direction (the direction from the outside toward the vehicle), and the-Y side corresponds to the outside in the vehicle width direction (the direction from the vehicle toward the outside). 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 includes double doors 2 that slide in the X direction to open and close the entrance 200. As shown in fig. 2, the door 2 includes a door 10 and a door hanger (connecting and moving part) 11 connected to the door 10.

The door 2 is defined by a guide rail, not shown, and moves on an opening/closing path for opening/closing the entrance 200 of the vehicle. The door 10 reciprocates in the X direction between the fully closed position and the 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. The drive source 3 is, for example, 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 provided to be rotatable (reversible) about an axis line along the X direction. The door 10 is reciprocated in the X direction between the fully closed position and the fully open position by the forward and reverse rotation of the motor.

The transmission mechanism 4 transmits a driving force from the driving 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 driving source 3, and an endless belt 42 that extends in the front-rear direction (X direction) of the vehicle.

The power conversion mechanism 41 converts rotation of the output shaft of the motor about an axis line along the X direction into rotation about an axis line 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 (an axis along the Y direction) is provided at a position apart from the gear 43 in the X direction.

The belt 42 is mounted on a gear 43 and a 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 belt 42 is mounted with a moving portion 5 that moves together with the belt 42. The moving portion 5 reciprocates in the front-rear direction (X direction) of the vehicle. 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 portion 5 reciprocates in the front-rear direction (X direction) of the vehicle between the fully-closed corresponding position and the fully-opened corresponding position in response to movement of the door 10 between the fully-closed position and the fully-opened position. The moving part 5 is attached to the outside of a belt 42 that is provided over a gear 43 and a pulley 44.

The position surrounded by the belt 42 and close to the gear 43 and the pulley 44 is referred to as the inside of the belt when viewed in the Y direction. In contrast, a position on the opposite side of the gear 43 and the pulley 44 with respect to the belt 42 is referred to as an outer side of the belt.

The fully-closed corresponding position and the fully-opened corresponding position of the moving portion 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 portion 5 has an upper moving portion 51 attached to the upper side of the belt 42 and a lower moving portion 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 right position that is close to the pulley 44 in the front-rear direction (X direction) of the vehicle. The fully-opened corresponding position of the upper moving portion 51 is a left position close to the gear 43.

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

The left door 10 shown in fig. 2 is connected to the upper moving portion 51 via a door hanger 11. The right door 10 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 to each other with the movement of the belt 42 in the front-rear direction (X direction) of the vehicle, and move by the same distance. Therefore, the fully-closed corresponding position of the upper moving portion 51 and the fully-closed corresponding position of the lower moving portion 52 are equidistant from the center of the entrance 200 in the front-rear direction (X direction) of the vehicle. Similarly, the fully-opened corresponding position of the upper moving portion 51 and the fully-opened corresponding position of the lower moving portion 52 are equidistant from the center of the entrance 200 in the front-rear direction (X direction) of the vehicle.

The upper moving portion 51 and the lower moving portion 52 each have a rectangular outer shape when viewed in the vehicle width direction (Y direction) of the vehicle.

As shown in fig. 2 to 4, the regulating portion 6 includes a right regulating portion 61 and a left regulating portion 62 corresponding to the upper moving portion 51 and the lower moving portion 52. Further, "right" and "left" are defined based on fig. 2, and are referred to as convenient.

The right regulating portion 61 is rotatably supported by a rotary shaft 61a having a rotation axis extending in the Y direction. The right regulating portion 61 is rotatably movable about a rotating shaft 61a between a locked position where the right regulating portion 61 is in contact with the upper moving portion 51 and an unlocked position where the right regulating portion 61 is not in contact with the upper moving portion 51 and does not interfere with the movement of the upper moving portion 51.

The right regulating portion 61 is rotated clockwise by about 90 ° about the rotation shaft 61a from the unlock position shown in fig. 2 to become the lock position.

The 1 st arm 61b is located at a position extending from the rotation shaft 61a to the-X direction at the unlock position. The 1 st arm 61b is located at a position extending from the rotation shaft 61a in the + Z direction at the locked position.

The 1 st arm 61b is located inside with respect to the belt 42 when located at the unlock position, as viewed from the Y direction. The 1 st arm 61b is rotationally moved to a position located outside with respect to the belt 42 when moving from the unlock position to the unlock position as viewed from the Y direction.

The 1 st arm 61b has a movement restricting portion 61d that comes into contact with the upper moving portion 51 at the locked position and blocks the movement of the upper moving portion 51 in the-X direction. The movement restricting portion 61d contacts the front surface 51a of the upper moving portion 51 in the-X direction with respect to the upper moving portion 51 located at the fully closing corresponding position (see fig. 7 described later). That is, the movement restricting portion 61d is located outside with respect to the belt 42 at the upper lock position, and the movement restricting portion 61d is disposed away from the rotation shaft 61a by a distance that can contact the front surface 51a of the upper moving portion 51.

The movement restricting portion 61d is located on the upper surface of the 1 st arm 61b in the + Z direction at the unlock position. The movement restricting portion 61d has a surface shape parallel to the front surface 51a of the upper moving portion 51 at the locked position so as to contact the front surface 51a of the upper moving 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 locking position.

The rotation shaft 61a is disposed closer to the-X direction than the front surface 51a of the upper moving portion 51 located at the fully closing corresponding position when viewed from the Y direction.

The 1 st arm 61b is connected to an upper lock portion 8, which will be described later, via a rotary shaft 61f provided at a position separated from the rotary shaft 61 a. The rotation shaft 61f has a rotation axis in the Y direction parallel to the rotation shaft 61 a. The movement restricting portion 61d is located at a position in the + Z direction with respect to the rotation shaft 61f when the 1 st arm 61b is located at the unlock position. When the right regulating portion 61 is located at the locked position, the rotation shaft 61f is located at a position in the + Z direction with respect to the rotation shaft 61 a.

Similarly, the 2 nd arm 61c is located at a position extending from the rotation shaft 61a in the + X direction at the unlock position. The 2 nd arm 61c is located at a position extending from the rotation shaft 61a in the-Z direction at the lock position.

The 2 nd arm 61c is located inside with respect to the belt 42 when located at the unlock position as viewed from the Y direction. When viewed from the Y direction, the 2 nd arm 61c is rotationally moved to a position not in contact with the belt 42 or a position not interfering with the belt 42 when moving from the unlock position to the unlock position.

The 2 nd arm 61c has an engaged portion 61e, and the engaged portion 61e comes into contact with a lock restricting portion 9 described later at the unlock position to prevent clockwise rotational movement of the right restricting portion 61 about the rotational shaft 61 a. In a state where the engaged portion 61e is in contact with the locking restricting portion 9, the right restricting portion 61 is restricted by the locking restricting portion 9 and rotation is prevented.

The left restriction portion 62 is point-symmetrical to the right restriction portion 61. Specifically, the left and right regulating

portions

62 and 61 are disposed in point symmetry with respect to a 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 regulating portion 62 is rotatably supported by a rotary shaft 62a having a rotation axis extending in the Y direction. The left regulating portion 62 is rotatably movable about a rotating shaft 62a between a locked position where the left regulating portion 62 is in contact with the lower moving portion 52 and an unlocked position where the left regulating portion 62 is not in contact with the lower moving portion 52 and does not interfere with the movement of the lower moving portion 52.

The left restricting portion 62 is rotated clockwise by about 90 ° about the rotation shaft 62a from the unlock position shown in fig. 2 to become the lock position.

The 1 st arm 62b is located at a position extending from the rotation shaft 62a in the + X direction at the unlock position. The 1 st arm 62b is located at a position extending from the rotation shaft 62a in the-Z direction at the lock position.

The 1 st arm 62b is located inside with respect to the belt 42 when located at the unlock position as viewed from the Y direction. The 1 st arm 62b is rotationally moved to a position located on the outer side with respect to the belt 42 when moving from the unlock position to the unlock position.

The 1 st arm 62b has a movement restricting portion 62d that comes into contact with the lower moving portion 52 when positioned at the locked position and blocks the movement of the lower moving portion 52 in the + X direction. The movement restricting portion 62d contacts the front surface 52a of the lower moving portion 52 in the + X direction with respect to the lower moving portion 52 located at the fully closing corresponding position (see fig. 7 described later). That is, the movement restricting portion 62d is located outside with respect to the belt 42 at the upper lock position, and the movement restricting portion 62d is disposed away from the rotation shaft 62a by a distance that can contact the front surface 52a of the lower moving portion 52.

The movement restricting portion 62d has a surface shape parallel to the front surface 52a of the lower moving portion 52 at the locked position so as to contact the front surface 52a of the lower moving portion 52 with as large an area as possible. That is, the movement restricting portion 62d has a surface along the YZ direction at the locking position.

The rotation shaft 62a is disposed closer to the + X direction than the front surface 52a of the lower moving portion 52 located at the fully closing corresponding position when viewed from the Y direction.

The 1 st arm 62b is connected to an upper lock portion 8 described later via a rotary shaft 62f provided at a position separated from the rotary shaft 62 a. The rotation shaft 62f has a rotation axis in the Y direction parallel to the rotation shaft 62 a. The movement restricting portion 62d is located closer to the Z direction than the rotation shaft 62f when the 1 st arm 62b is located at the unlock position.

The 2 nd arm 62c has an engaged portion 62e, and when the engaged portion 62e is located at the unlock position, the engaged portion 62e comes into contact with a lock restricting portion 9 described later to prevent clockwise rotational movement of the left restricting portion 62 about the rotational shaft 62 a. In a state where the engaged portion 62e is in contact with the locking restricting portion 9, the left restricting portion 62 is restricted by the locking restricting portion 9 and rotation is prevented.

The operation section 7 is manually operated to generate an operation force for operating the upper lock section 8.

As shown in fig. 3 and 4, the operation unit 7 includes: an input unit 71 for inputting an operation force by a manual operation; and a switching part 72 for switching the direction of the operation force inputted from the input part 71 and transmitting the operation force to the upper lock part 8.

arms

81b, 81c extend in the X direction and face opposite to the unlock position.

One end of a left 2 nd link (2 nd link) 83 is connected to a distal end of the arm 81b via a rotation shaft 81 d. One end of a right 2 nd link (2 nd link) 82 is connected to a distal end of the arm 81c via a rotation shaft 81 e.

A stopper 81g is formed at the tip of the arm 81c at a position farther from the rotation shaft 81a than the rotation shaft 81 e. The stop portion 81g stops the 1 st link 81 at the lock up position to restrict the rotational position. The stop portion 81g abuts against the stop restricting portion 84 at the lock up position to restrict the position.

The arm 81c has a switch pressing portion at a distal end thereof, which contacts the lock switch 103. The switch pressing portion can also serve as the stop portion 81 g. The locking switch 103 turned on by contact with the switch pressing portion detects that the 1 st link 81 is located at the locking position. That is, the locking switch 103 detects that the moving portion 5 is located at the fully-closed corresponding position and the restricting portion 6 is located at the locking position.

This allows the locking switch 103 to be used as a switch for detecting full-closure of the door during normal vehicle operation.

The rotating shaft 81d is disposed at a position separated from the rotating shaft 81a in the + X direction at the unlock position. The rotation shaft 81e is disposed at a position separated from the rotation shaft 81a in the-X direction at the unlock 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 other end of the left 2 nd link (2 nd link) 83 is rotatably connected to the left regulating portion 62 via a rotation shaft 62 f. The left 2 nd link (2 nd link) 83 extends from the rotation shaft 81d toward the-X direction at the unlock position.

The right regulating portion 61 is rotatably connected to the other end of the right 2 nd link (2 nd link) 82 via a rotation shaft 61 f. The right 2 nd link (2 nd link) 82 extends from the rotation shaft 81e toward the + X direction at the unlock position.

In the unlock position, the arm 81b extends from the rotation shaft 81a toward the + X direction, and the left 2 nd link (2 nd link) 83 extends from the rotation shaft 81d toward the-X direction. In the unlock position, the arm 81b is disposed parallel to the left 2 nd link (2 nd link) 83 and overlapping when viewed from the Y direction. Therefore, the left 2 nd link (2 nd link) 83 has a bent portion 83a bent from the rotation axis 81d in the-Z direction so as to avoid the rotation axis 81e at a position close to the rotation axis 81 d.

In the unlock position, the arm 81c extends from the rotation shaft 81a toward the-X direction, and the right 2 nd link (2 nd link) 82 extends from the rotation shaft 81e toward the + X direction. In the unlock position, the arm 81c is disposed in parallel with the right 2 nd link (2 nd link) 82 so as to overlap when viewed from the Y direction. Therefore, the right 2 nd link (2 nd link) 82 has a bent portion 82a bent from the rotation axis 81e in the + Z direction so as to avoid the rotation axis 81d, at a position close to the rotation axis 81 e.

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

The arm 81b, the left 2 nd link (2 nd link) 83, and the left restriction 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 2 nd link (2 nd link) 82, and the right regulating portion 61 form a lock link that regulates the movement of the upper moving portion 51 at the fully-closed corresponding position.

When the operation force is input from the operation unit 7, the 1 st link 81 rotates clockwise in fig. 2 and abuts against the stop restricting portion 84, and the upper lock 8 is positioned at the locking position.

In the locked position, the 1 st link 81 is in a horizontal position, i.e., a rotational position in which the arm 81b is along the-X direction and the arm 81c is oriented in the + X direction around the rotational shaft 81 a. At this time, as shown in fig. 7 to be described later, the right 2 nd link 82 is positioned above the rotation shaft 61f in the Z direction with respect to the rotation shaft 81 e. Similarly, the left 2 nd link 83 is positioned below the rotation shaft 62f in the Z direction with respect to the rotation shaft 81 d.

That is, in the process of rotating from the unlock position to the lock-up position, the 1 st link 81 and the 2 nd links 82, 83 further rotate beyond the state of the dead points aligned in a straight line. Therefore, when returning from the locked position to the unlocked position, the 1 st link 81 and the 2

nd links

82 and 83 need to rotate beyond the dead point again.

The 1 st link 81 is rotated counterclockwise by the operation force input from the operation unit 7, and the upper lock portion 8 is brought into the unlock position when it is in the horizontal position shown in fig. 2.

The locking restriction unit 9 allows locking by the upper lock unit 8 to be performed only when the door 10 is at the fully closed position.

As shown in fig. 2 to 4, the lock restricting portion 9 includes a right lock restricting portion 91 and a left lock restricting portion 92.

The right locking restriction unit 91 can restrict locking of the right restriction unit 61.

The right lock restriction portion 91 is rotatably supported by a rotary shaft 91a having a rotation axis extending in the Y direction. The right lock restricting portion 91 is rotatably movable about a rotation shaft 91a between a lockable position where the right lock restricting portion 91 is pressed by the upper moving portion 51 by contact with the upper moving portion 51 and an unlocked position where the right lock restricting portion 91 is not pressed by the upper moving portion 51 or the upper moving portion 51.

The rotary shaft 91a is disposed inward of the belt 42 when viewed in the Y direction. The rotation shaft 91a is disposed at a position close to the upper moving portion 51 located at the fully-closed corresponding position. The rotation shaft 91a is disposed at a position close to the upper moving portion 51 located at the fully-closed corresponding position in the-Z direction and aligned with the upper moving portion in the X direction when viewed from the Y direction. A torsion spring, not shown, is mounted around the rotation shaft 91 a. The torsion spring biases the right lock restricting portion 91 counterclockwise about the rotation shaft 91a in fig. 2.

The right lock restriction portion 91 is a cam having a 1 st arm 91b and an engagement portion 91h, the 1 st arm 91b extending from the rotation shaft 91a in the + Z direction, the engagement portion 91h protruding in the-X direction from the base end side of the 1 st arm 91 b.

The 1 st arm 91b has a pressed portion 91d at a distal end position, and the pressed portion 91d is pressed by the upper moving portion 51 by being in contact with the upper moving portion 51.

The pressed portion 91d is formed to protrude in the-X direction from the tip of the 1 st arm 91b extending from the rotation axis 91a in the + Z direction. When the pressed portion 91d is pressed in the + X direction, the 1 st arm 91b can be rotationally moved about the rotation shaft 91a from the lockable position to the non-lockable position. The pressed portion 91d is pressed by contacting the front surface 51b facing forward when the upper moving portion 51 moves forward in the + X direction. In a state where the pressing from the upper moving portion 51 is lost and the front surface 51b is not in contact with the pressed portion 91d, the 1 st arm 91b is returned from the lockable position to the non-lockable position by the torsion spring around the rotation shaft 91 a.

The right lock restricting portion 91 is rotatable about a rotation shaft 91a between an unlocked position in which the tip end of the 1 st arm 91b extends in the + Z direction and a lockable position in which the tip end of the 1 st arm 91b is inclined in the + X direction with respect to the unlocked position. The right lock restricting portion 91 is moved to the lockable position by being rotated clockwise about the rotation shaft 91a from the unlocked position shown in fig. 2 (see fig. 5 to 7 described later).

When the lock member is located at the unlocked position, the engaging portion 91h contacts the engaged portion 61e to prevent the right regulating portion 61 from rotating. When the locking portion is located at the lockable position, the engaging portion 91h is separated from the engaged portion 61e without interfering with the movement of the right regulating portion 61.

In the right locking restriction portion 91, the 1 st arm 91b is rotated to a lockable position by pressing the upper moving portion 51 against the pressed portion 91d, and the engagement portion 91h and the engaged portion 61e are released from contact with each other and can be locked by the right restriction portion 61.

The left lock restriction portion 92 is point-symmetrical to the right lock restriction portion 91.

Specifically, the left lock restricting portion 92 and the right lock restricting portion 91 are disposed in point symmetry with respect to a 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 locking restriction unit 92 can perform locking restriction on the left restriction unit 62. The left lock restricting portion 92 is rotatably supported by a rotary shaft 92a having a rotation axis extending in the Y direction. The left-lock restricting portion 92 is rotatably movable about a rotation shaft 92a between a lockable position where the left-lock restricting portion 92 is in contact with the lower moving portion 52 and pressed by the lower moving portion 52, and an unlocked position where the left-lock restricting portion 92 is not in contact with the lower moving portion 52 or pressed by the lower moving portion 52.

The rotation shaft 92a is disposed inward of the belt 42 when viewed from the Y direction. The rotation shaft 92a is disposed at a position close to the lower moving portion 52 located at the fully-closed corresponding position. The rotation shaft 92a is disposed at a position close to the + Z direction of the lower moving portion 52 located at the fully-closed corresponding position and aligned therewith in the X direction when viewed from the Y direction. A torsion spring, not shown, is mounted around the rotation shaft 92 a. The torsion spring biases the left lock restricting portion 92 counterclockwise about the rotation shaft 92a in fig. 2.

The left lock restriction portion 92 is a cam having a 1 st arm 92b, a 2 nd arm 92c, and an engagement portion 92h, the 1 st arm 92b extending from the rotation shaft 92a in the-Z direction, the 2 nd arm 92c extending from the rotation shaft 92a in the + Z direction, and the engagement portion 92h protruding in the + X direction from the base end side of the 1 st arm 92 b.

The 1 st arm 92b has a pressed portion 92d at a distal end position, and the pressed portion 92d is pressed by the lower moving portion 52 by being in contact with the lower moving portion 52. The pressed portion 92d is formed to protrude in the + X direction from the distal end of the 1 st arm 92b extending in the-Z direction from the rotation axis 92 a.

When the pressed portion 92d is pressed in the-X direction, the 1 st arm 92b can be rotationally moved about the rotational shaft 92a from the lockable position to the lockable position. The pressed portion 92d is pressed by contacting the front surface 52b facing forward when the downward moving portion 52 moves forward in the-X direction. In a state where the pressing from the lower moving portion 52 disappears and the front surface 52b is not in contact with the pressed portion 92d, the 1 st arm 92b is returned from the lockable position to the unlockable position by the torsion spring around the rotation shaft 92 a.

The 2 nd arm 92c has a switch pressing portion 92e at a tip end thereof, which contacts the fully-closed switch 102. The fully-closed switch 102 that is 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 the left-lock restricting portion 92 is located at the lockable position. That is, the full close switch 102 detects that the moving portion 5 is located at the full close corresponding position and the locking restricting portion 9 is located at the lockable position.

The left lock restricting portion 92 is rotatable about a rotation axis 92a between an unlocked position in which the tip end of the 1 st arm 92b extends in the-Z direction and a lockable position in which the tip end of the 1 st arm 92b is inclined in the-X direction with respect to the unlocked position. The left lock restricting portion 92 is moved to the lockable position by being rotated clockwise about a rotation shaft 92a from the unlocked position shown in fig. 2 (see fig. 5 to 7 described later).

When the lock is not locked, the engaging portion 92h contacts the engaged portion 62e to prevent the rotation of the left restricting portion 62. When the left restricting portion 62 is located at the lockable position, the engaging portion 92h is separated from the engaged portion 62e without interfering with the movement of the left restricting portion 62.

In the left locking restricting portion 92, the 1 st arm 92b is rotated to a lockable position by pressing the pressed portion 92d from the lower moving portion 52, and the engagement portion 92h and the engaged portion 62e are released from contact with each other, so that the left restricting portion 62 can be locked.

At the same time, the 2 nd arm 92c rotates integrally with the 1 st arm 92b, so that the switch pressing portion 92e contacts the fully-closed switch 102. Thus, the full close switch 102 detects the full close corresponding position and outputs the detected position.

The full close switch 102 is connected to an interlock circuit that transmits a full close signal when all the doors 2 are fully closed, and when the upper lock portion 8 is locked, the full close switch 102 bypasses the interlock circuit and is connected so as to be able to always transmit the full close signal.

In the railway door device 100 according to the present embodiment, the moving portion 5 does not abut against the locking restriction portion 9 in a state where the door 2 shown in fig. 2 is opened or at least not fully closed. Therefore, the lock restricting portion 9 maintains the non-lockable position, and the operation restriction of the restricting portion 6 by the lock restricting portion 9 is maintained. Therefore, the restricting unit 6 maintains the unlock position, and thus, manual locking is restricted.

As shown in fig. 5, in a state where the door 2 is closed, that is, in a state where the door 10 reaches the fully closed position, the moving part 5 abuts against the locking restricting part 9, and therefore the locking restricting part 9 is in the lockable position. This releases the restriction of the operation of the restriction unit 6 by the locking restriction unit 9. At the same time, the full close switch 102 detects that the door 10 has reached the full close position.

Here, when the door 2 is manually locked, it is necessary to lock the door only in a state where the door 10 reaches the fully closed position.

In this state, when the operation unit 7 is locked, 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 1 st link 81 of the locking unit 8 rotates.

When the door 10 is at the fully closed position and the operation unit 7 performs the locking operation, the 1 st link 81 of the locking unit 8 rotates from the unlocked position shown in fig. 2 to 5 to the locked position shown in fig. 7 through the state shown in fig. 6.

The stop portion 81g abuts against the stop restricting portion 84 to stop the rotation at the upper lock position. As the 1 st link 81 rotates, the 2

nd links

82 and 83 are also rotated in conjunction with the right and left

restrictions

61 and 62. Thus, in the locked position, as shown in fig. 7, the 2

nd links

82 and 83 are positioned as follows with respect to the 1 st link 81 oriented in the horizontal direction (X direction): the

rotation shafts

61f, 62f of the end portion on the restricting portion 6 side are farther from the 1 st link 81 in the Z direction than the

rotation shafts

81d, 81e of the end portion on the 1 st link 81 side.

That is, as shown in fig. 7, the right 2 nd link 82 is in the locked position in a state rotated by an angle θ 2 exceeding 180 ° about the rotation axis 81e with respect to the 1 st link 81. Further, the left 2 nd link 83 is rotated by an angle θ 3 exceeding 180 ° around the rotation axis 81d with respect to the 1 st link 81, and is in the locked position.

The right 2 nd link 82 is inclined upward about the rotation axis 81e by an angle θ 2 with respect to the horizontal direction with respect to the 1 st link 81. This is because the right regulating portion 61 is rotated to the locked position where the rotation shaft 61f of the right regulating portion 61 is positioned outside the belt 42 and the rotation shaft 61f is positioned in the + Z direction with respect to the rotation shaft 61 a.

The left 2 nd link 83 is inclined downward by an angle θ 3 with respect to the horizontal direction about the rotation axis 81d with respect to the 1 st link 81. This is because the left regulating portion 62 is rotated to the locked position where the rotation shaft 62f of the left regulating portion 62 is positioned outside the belt 42 and the rotation shaft 62f is positioned in the-Z direction with respect to the rotation shaft 62 a.

At the locked position, the moving portion 5 is to be moved from the fully-closed corresponding position in the case of attempting to open the door 2. In this case, the moving portion 5 is advanced toward the fully open corresponding position.

Then, in the right regulating portion 61, the movement regulating portion 61d is pressed in the-X direction by the front surface 51a of the upper moving portion 51. Then, when viewed from the + Y direction, a force acts to rotate the right regulating portion 61 counterclockwise about the rotation shaft 61 a. This force is transmitted to the 2 nd link 82 of the upper lock portion 8. At this time, the force acts along the axis of the 2 nd link 82 and is transmitted from the rotating shaft 81e to the 1 st link 81.

As described above, in the unlocked position, the right 2 nd link 82 is at an angular position beyond the dead point with respect to the 1 st link 81. Therefore, the line of action of the force trying to open the door 2, which is transmitted from the right 2 nd link 82 to the 1 st link 81, is directed in the locked rotational direction, and the rotation of the 1 st link 81 is restricted by the stop restricting portion 84.

Similarly, in the left regulating portion 62, the movement regulating portion 62d is pressed in the + X direction by the front surface 52a of the lower moving portion 52. Then, when viewed from the + Y direction, a force acts to rotate the left regulating portion 62 counterclockwise about the rotation shaft 61 a. This force is transmitted to the 2 nd link 83 of the upper lock portion 8. At this time, the force acts along the axis of the 2 nd link 83 and is transmitted from the rotary shaft 81d to the 1 st link 81.

As described above, in the up-lock position, the left 2 nd link 83 is at an angular position beyond the dead point with respect to the 1 st link 81. Therefore, the line of action of the force trying to open the door 2, which is transmitted from the left 2 nd link 83 to the 1 st link 81, is directed to the locked rotational direction, and the rotation of the 1 st link 81 is restricted by the stop restricting portion 84.

That is, if the 2

nd links

82 and 83 are not rotated beyond the dead point, they cannot be rotated in the unlocking direction. Therefore, the locked state by the manual operation can be maintained without adding another structure.

The state beyond the dead point is maintained in a locked state in a point-symmetric state with respect to the rotation axis 81a when viewed from the Y direction by the 1 st link 81, the 2 nd link 82, and the 2 nd link 83. 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 railway door apparatus 100 according to the present embodiment, in the manual locking apparatus 101, 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 10 are locked by the right regulating part 61 and the left regulating part 62 of the regulating part 6, respectively, so that the door 10 cannot be opened or closed. This makes it possible to lock the door leaf with a smaller restraining force than when the door leaf is directly locked.

In the railway door apparatus 100 according to the present embodiment, when the locking is performed manually, the locking restriction unit 9 abuts against the restriction unit 6 in the manual locking apparatus 101, and the locking operation is restricted so as not to be performed. When the door 10 is not in the fully closed state at the fully closed position, the locking restriction portion 9 is not separated from the restriction portion 6. Therefore, when the door 10 is not located at the fully closed position, manual locking is restricted to be impossible.

Further, the doors 10 that open both sides can be simultaneously locked by key operation of the operation portion 7, and the locked state can be maintained.

Thus, for example, even in an emergency such as when the door 2 is broken, if the door cannot be driven for closing, for example, when the vehicle is required to travel, the locking operation in the fully closed state can be reliably performed manually. In particular, compared to a mechanism that directly locks the door 10, the door 10 can be reliably locked even when the door 10 is broken, and safety can be improved.

Further, since the door 10 cannot be locked when it is out of the fully closed position, malfunction can be prevented and safety can be improved. The locking can be reliably performed with a smaller member and a smaller restricting force than the mechanism that directly locks the door 10.

According to the above configuration, the locking restricting portion 9 abuts against the moving portion 5 and moves from the locking restricting position to the unlocking restricting position, thereby enabling the locking operation of the restricting portion 6 and the upper lock portion 8. Therefore, the lock restriction portion (closing plate) is not required to be provided over the entire area in the opening/closing direction, and the lock can be manually locked only at the fully closed position.

In the manual locking device according to the present invention, the locking mechanism may include a locking restriction unit that allows the locking mechanism to lock the door only when the door is at the fully closed position.

Accordingly, the door cannot be locked unless the door is fully closed, and therefore, safety can be improved.

In the manual lock device according to the present invention, the restricting portion may have an engaged portion. Further, the locking restriction unit may include: an engaging portion that is in contact with the engaged portion to interfere with movement of the restricting portion; and a pressed portion that is pressed in a closing direction by the moving portion when the door reaches the fully closed position, and that releases contact between the engaging portion and the engaged portion.

Thus, the unlocking/locking can be switched only by the presence or absence of the pressing of the pressed portion by the moving portion, the number of components can be reduced, and the operational reliability can be improved.

In the manual lock-up device according to the present invention, the lock-up restriction portion may be a cam including a pressed portion and an engagement portion, and the cam may be rotated by being pressed by the pressed portion, thereby releasing contact between the pressed portion and the engagement portion.

This makes it possible to reliably switch between contact and release between the engaged portion and the engaging portion.

The manual locking device according to the present invention may further include a full close switch for detecting that the door leaf has reached the full close position. The cam may further include a switch pressing portion that is pressed by the pressing portion to rotate, thereby pressing the fully-closed switch.

Thus, the fully closed state can be detected without directly detecting the position of the door.

In the manual lock device according to the present invention, the manual lock device may be provided in a plurality of doors that open and close a plurality of boarding/alighting ports of the railway vehicle. The full close switch may be connected to an interlock circuit that transmits the full close signal when all the doors are fully closed, and may be connected to bypass the interlock circuit so as to always transmit the full close signal when the locking portion is locked by manually operating the operating portion.

This enables lock detection at an emergency time when the lock is manually operated. Further, the present invention can be used as a full-close switch for detecting full-close in normal door opening and closing.

In the manual locking device of the present invention, the locking unit may include: a 1 st link rotated by an operation force of the operation portion; and a 2 nd link, one end of which is connected to the end of the 1 st link and the other end of which is connected to the restricting portion, wherein the 1 st link rotates from the unlock position to the lock position, and the 1 st link and the 2 nd link become the lock position at positions beyond the dead point.

Thus, the locking is performed at a position where the angle between the 1 st link and the 2 nd link exceeds the dead point, and therefore, a structure for fixing the 1 st link and the 2 nd link at the locking position is not necessary, and the locking can be performed reliably.

In the manual locking device of the present invention, the 2 nd link may extend along the moving direction of the moving portion at the locking position.

Thus, when the moving portion attempts to unlock the lock, the 2 nd link is pressed in the direction in which the 2 nd link extends, and the locked state is easily maintained even if a large force is applied.

In the manual lock-up device according to the present invention, the regulating portion connected to the 2 nd link may contact a position of the moving portion toward the fully open corresponding position when the door is at the fully closed position.

Thus, the movement of the moving portion can be effectively restricted because the restricting portion restricts the moving portion by coming into direct contact with a portion ahead in the moving direction from the fully closed position, which is one end of the moving range of the moving portion.

In the manual locking device according to the present invention, the locking portion may simultaneously lock the moving portions connected to the sliding door leaves that are opened in both directions by the operating force of the operating portion.

This allows the double door leaves to be locked at the same time, and prevents the door leaves from being unlocked on one side.

In the manual lock-up device according to the present invention, the operation portion may be provided at the center of the door leaves that are opened in both directions in the moving direction of the moving portion.

This allows the double door leaves to be locked at the same time, and improves operability.

In the manual lock device according to the present invention, the transmission mechanism may include a coupling moving portion that moves integrally with the moving portion.

Thus, when the driving force is transmitted by any one of the mechanisms such as a wrap-around type, a rack and pinion type, a screw type, a linear motor type, and an electric cylinder as the transmission mechanism, the locking can be reliably performed in any one of the case where these mechanisms and the moving portion move integrally and the case where the moving portion moves integrally with the door hanger.

In the manual lock device according to the present invention, the operation portion may include an input portion that inputs an operation in an upward direction in the vertical direction.

This can improve the operability of the locking operation.

In the manual lock-up device according to the present invention, the operation portion may include a conversion portion that converts an operation force input upward in the vertical direction from the input portion into a lateral direction that intersects the moving direction of the moving portion.

This allows the door to be attached to a position above the door of the entrance, thereby saving space. Further, since the keyhole of the operation portion is not visible from the vehicle center position in the vehicle width direction, the design can be improved.

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

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

The moving portion 5 (the upper moving portion 5 and the lower moving portion 52) may not be connected to the door hanger 11. In this case, the moving portion 5 (the upper moving portion 5, the lower moving portion 52) may be provided on the belt 42 at a position different from the position connected to the door hanger 11.

The upper lock portion 8 may be configured other than a link mechanism. In this case, the 2 nd arm 61c of the right regulating portion 61 and the 2 nd arm 62c of the left regulating portion 62 may be configured to be rotated so as to come close to the rotation shaft 81a at the same time and be located at the locked position. In this case, a structure for returning by rotating in the opposite direction to the locking may be provided.
