A door device for a railway vehicle includes a door body and a lock mechanism that locks the door body in a state where the door body is closed. During the running of the vehicle body, the door body is locked by controlling the locking mechanism so that the door device is not accidentally opened, and the safety of the passenger is achieved. On the other hand, in an emergency, there is a case where it is desired to open the door body. Therefore, there is a manual unlocking device for manually unlocking the locked locking mechanism. Such manual unlocking devices are sometimes called EVAC (emergency evacuation: emergency evacuation).

When a passenger presses a button or the like provided near the door body, a request signal for requesting unlocking of the door body is transmitted to the door device. When the door device confirms that the vehicle speed is equal to or lower than a certain speed, the actuator that locks the operation of the lever provided in the vicinity of the door main body is driven to allow the lever operation. Thereby, the passenger uses the lever to manually operate the locking mechanism, thereby mechanically unlocking.

As such, the EVAC is designed so that the passenger can only use the manual unlocking device when it is safe to open the door.

The latch lever 11 and the latch lever 12 have the same shape as each other, and are arranged at mutually symmetrical positions in the Z direction with respect to the axis of the cylinder 151 .

The latch levers 11 and 12 are rotatably connected to the base 5 by the rotation shafts 11a and 12a. Both the rotation shafts 11a and 12a are arranged at positions slightly shifted to the −X direction side from the central position in the X direction of the latch levers 11 and 12 . The rotation shafts 11a and 12a extend in the Y direction and are arranged parallel to each other. The rotation shafts 11a and 12a are arranged so as to be orthogonal to the axis of the cylinder 151 when viewed from the Z direction. When viewed from the Z direction, the rotation shafts 11a and 12a are arranged so as to overlap each other.

The latch lever 11 and the latch lever 12 can mutually rotate symmetrically about the rotation axes 11a and 12a.

The claw (first hooking portion) 11b of the latch lever 11 and the claw (second hooking portion) 12b of the latch lever 12 are arranged so as to sandwich the piston 152 and can be hooked to the groove (the first hooked portion). The hook part) 152a and the groove (2nd hooked part) 152b are arrange|positioned.

Claws 11b and 12b which can be hooked to grooves 152a and 152b functioning as hooked portions are formed at the end portions (one ends) of the latch levers 11 and 12 in the +X direction.

Rollers 13a and 13b are provided at the ends (the other ends) in the −X direction of the latch levers 11 and 12 , respectively. In the latch lever 11, the pawl 11b and the roller 13a are provided at the ends on the opposite side with respect to the rotation shaft 11a. In the latch lever 12, the pawl 12b and the roller 13b are provided in the end part on the opposite side with respect to the rotating shaft 12a.

The rollers 13a and 13b are arranged so as to sandwich the actuator rod 14a in the Z direction, and are arranged so as to be in contact with the actuator rod 14a.

The rollers 13a and 13b have the same shape as each other, and are arranged at mutually symmetrical positions in the Z direction with respect to the axis of the cylinder 151 . The roller 13a and the roller 13b are opposed to each other in the Z direction. The roller 13a and the roller 13b are separated from each other by a distance by which the actuator rod 14a of the actuator 14 can be inserted.

The actuator 14 can reciprocate the actuator rod 14a in the X direction (the axial direction of the actuator rod 14a). The actuator 14 is, for example, an electric solenoid.

The actuator rod 14a is moved in the +X direction by the actuator 14 so as to come into contact with the rollers 13a and 13b. The actuator rod 14a is moved in the −X direction by the actuator 14, and is separated from the roller 13a and the roller 13b. Thus, when the actuator lever 14a moves in the X direction, the roller 13a and the roller 13b rotate in directions opposite to each other.

When the actuator rod 14a is moved in the +X direction so as to be extended by the actuator 14, the actuator rod 14a is positioned between the rollers 13a and 13b as described above and comes into contact with the rollers 13a and 13b on state. At this time, the latch lever 11 and the latch lever 12 rotate around the rotation shafts 11a and 12a so that the rollers 13a and 13b are separated from each other, and the angles of the latch levers 11 and 12 are fixed. Then, the claw 11b and the claw 12b are brought into a state of approaching each other.

Thereby, the pawl 11b enters the inside of the groove 152a, comes into contact, and is hooked on the groove 152a. Similarly, the pawl 12b enters into the groove 152b, makes contact, and is hooked on the groove 152b. As a result, the piston 152 is in a state of being held by the pawls 11b and 12b from both sides in the Z direction. Therefore, neither the claw 11b nor the claw 12b is disengaged from the grooves 152a, 152b.

Therefore, the movement of the piston 152 in the X direction is restricted. Therefore, the movement in the X direction of the block 2 integrated with the piston 152 is also restricted.

When the actuator rod 14a is moved in the -X direction in a retracted manner by the actuator 14, the actuator rod 14a is moved in the -X direction from the position between the rollers 13a and 13b as described above, and becomes A state not in contact with the rollers 13a and 13b.

Therefore, the rollers 13a and 13b have no restriction from the actuator rod 14a. Thereby, the latch lever 11 and the latch lever 12 rotate about the rotation shafts 11a and 12a so that it may approach each other. Then, the claw 11b and the claw 12b are separated from each other.

Thereby, the pawl 11b moves from the groove 152a in the +Z direction to release the contact. Similarly, the pawl 12b moves in the −Z direction from the groove 152b to release the contact. Thereby, both the claw 11b and the claw 12b are disengaged from the grooves 152a and 152b. The piston 152 is in a state of being separated from the pawl 11b and the pawl 12b.

Therefore, the movement in the X direction of the piston 152 can be moved without being restricted. Therefore, the movement in the X direction of the block 2 integral with the piston 152 is not restricted.

In this way, the actuator 14 rotates the rollers 13a and 13b by the actuator lever 14a, thereby releasing the restriction on the transmission of the operation force accumulated in the force accumulating portion 130 to the unlocking portion 150 .

According to the manual door release device 100 of the present embodiment, the locking of the door leaf 10 is unlocked by pulling the link 1 whose distal end is connected to the unlocking lever (not shown) of the locking mechanism 110 in the −X direction.

The movement of the link 1 is linked to the movement of the block 2 of the EVAC connected to the other end 1 b of the link 1 . The rods 3 and 4 penetrating the block 2 receive the elastic force of springs 68 and 78 provided inside the cylinders 6 and 7 guided by the base 5 .

Cylinder end portions 65 and 75 are fixed to the cylinders 6 and 7 . The cylinder ends 65 and 75 are connected to a rope (cable) 123 connected to the vehicle inner operation part 121 and a rope (cable) 124 connected to the vehicle outer operation part 122 via the cable fixing parts 66 and 76 . Thereby, the cylinders 6 and 7 are respectively pulled and moved in the −X direction.

As the vehicle inner power storage unit 131 , the cylinder 6 is pulled in the −X direction by the operation of the vehicle inner operation unit 121 via the rope (cable) 123 to move.

As the vehicle outside power storage unit 132 , the cylinder 7 is pulled and moved in the −X direction via the rope (cable) 124 by the operation of the vehicle outside operation unit 122 .

The vehicle inner power storage portion 131 and the vehicle outer power storage portion 132 can operate independently.

According to the restricting portion 140, the latch levers 11, 12 located in the center of the base 5 are rotated about the rotation shafts 11a, 12a, so that the restricting state and the non-restricting state can be switched based on the hooking of the claws 11b, 12b and the grooves 152a, 152b. restricted state. This switching can be switched by whether or not the actuator rod 14a that advances and retreats by the actuator 14 is in contact with the rollers 13a and 13b.

＜Normal state＞

The locking mechanism 110 locks the door leaf 10 in a normal state such as vehicle running. At the same time, the actuator 14 is set non-unlockable, as shown in FIG. 5, the actuator rod 14a is in the extended position. The claws 11b and 12b are hooked to the grooves 152a and 152b. Therefore, the block 2 and the link 1 are in a restricted state in which they cannot move relative to the base 5 .

＜Unlocking action＞

For example, in an emergency, the in-vehicle operation unit 121, which is a handle or the like, is operated. Thereby, as shown in FIG. 3 , the manual door releasing device 100 pulls the rope fixing portion 66 , the cylinder end portion 65 , and the cylinder 6 in the −X direction as one body via the rope 123 .

Here, when the vehicle inner operating portion 121 cannot be unlocked (the vehicle is running, or the vehicle cannot get on and off because of the door on the opposite side of the platform), the actuator lever 14a is in the extended position, and the rollers 13a, 13b contacts. Thus, the movement of the latch levers 11, 12 is restricted.

The claws 11b and 12b at the top ends of the latch levers 11 and 12 are hooked on the grooves 152a and 152b of the piston 152, and therefore, the movement of the block 2 integrated with the piston 152 is restricted. Therefore, the block 2 maintains the same position with respect to the base 5 as before the operation portion 120 is operated.

Since the rod 3 is hooked to the block 2 by the detachment preventing portion 3a, the rod 3 does not move together with the cylinder 6, and the stroke is restricted. Therefore, the rod 3 maintains the position in the X direction.

Therefore, as shown in FIG. 3 , the spring 68 contracts due to the stroke of the cylinder 6 . The operating force is accumulated in the spring 68 by the stroke of the cylinder 6 . Therefore, when unlocking is performed in an emergency, first, the handle of the vehicle inner side operation unit 121 is held in the pulled position. Furthermore, the spring 68 is maintained in a state in which the operating force (elastic force) is stored in the vehicle inner power storage portion 131 .

At this time, as shown in FIG. 3 , the rope fixing portion 66 pushes the switches 161 and 163 . Therefore, the switches 161, 163 issue a signal for unlocking.

The signal is transmitted to the superiors who control the vehicle, such as the flight attendant and the operation control room, and are required to judge whether the lock can be released or not.

In addition, since the switches 161 and 163 respectively issue signals for different upper-level controls, two switches are provided in order to satisfy the operational reliability.

At this time, since the vehicle outer side operating portion 122 is not operated, as shown in FIG. 3 , the vehicle outer side power accumulating portion 132 is not changed from the normal state. That is, the vehicle inner power storage portion 131 can store the operation force independently of the vehicle outer power storage portion 132 .

When it is determined by the superior (vehicle, ATC) that the unlocking is possible (the vehicle is stopped, the entrance and exit 105 on the platform side), the actuator 14 is demagnetized, for example, by the unlocking signal from the superior command. Thereby, the actuator rod 14a moves in the -X direction, and becomes a retracted position. In addition, when emergency evacuation or power failure is required, such as when an emergency occurs, the actuator 14 is similarly demagnetized.

The actuator rod 14a which moved in the -X direction and is in the retracted position is separated from the rollers 13a and 13b and becomes non-contact. Therefore, the movement of the latch levers 11 and 12 is not restricted. Therefore, the claws 11b and 12b of the top ends of the latch levers 11 and 12 are separated from the grooves 152a and 152b of the piston 152 . Therefore, the movement of the block 2 integral with the piston 152 becomes an unrestricted state where it is not restricted. Therefore, the piston 152 can move relative to the base 5 from the position before the operation part 120 is operated. That is, the block 2 can move in the −X direction with respect to the base 5 .

Then, the lever 3 is moved in the −X direction by the operating force (elastic force) accumulated by the contracted spring 68 . Thereby, the block 2 moves in the −X direction together with the rod 3 . Therefore, the piston 152 of the block 2 moves in the −X direction with respect to the base 5 .

When the block 2 is moved in the -X direction by the operating force (elastic force) of the spring 68, the claws 11b and 12b of the latch levers 11 and 12 are formed in the slope-shaped grooves 152a, 152a, 152b is pushed up and disengaged.

In addition, when the block 2 moves in the −X direction, it moves in a state where the posture is controlled by the piston 152 . At the same time, the block 2 synchronizes the movement in the X direction with respect to the base 5 by means of the links 62a, 62b as the synchronizing mechanism of the arm part 22 and the links 72a, 72b as the synchronizing mechanism of the arm part 23.

Thereby, the link 1 connected to the block 2 moves in the -X direction, and the locking of the door leaf 10 by the locking mechanism 110 is released.

In addition, due to the unlocking operation, the spring 153 contracts, and elastic force is accumulated in the spring 153 . At this time, the spring 68 accumulates an elastic force in balance with the elastic force of the spring 153 .

Here, the unlocking is usually performed by one of the vehicle inner operating portion 121 or the vehicle outer operating portion 122 , so the block 2 is pulled by the single cylinders 6 and 7 , and torque is generated, which may cause malfunction.

However, in the present embodiment, the movement of both ends in the Y direction of the block 2 can be mechanically synchronized by the links 62a, 62b, 72a, and 72b, so that a smooth lock release operation can be performed.

In the above-mentioned unlocking operation, the method of releasing the lock by the operation of the vehicle inner operating portion 121 has been described.

In this case, the vehicle inner operation part 121 , the rope 123 , the rope fixing part 66 , the cylinder end part 65 , the cylinder 6 , the spring 68 , the switches 161 and 163 , the rod 3 , the arm part 22 , and the links 62 a and 62 b are respectively renamed. These are the vehicle outer side operation part 122, the rope 124, the rope fixing part 76, the cylinder end part 75, the cylinder 7, the spring 78, the switches 162 and 164, the lever 4, the arm part 23, and the links 72a and 72b.

Furthermore, when both the vehicle inner operation unit 121 and the vehicle outer operation unit 122 are operated before the unlock signal reaches the actuator 14, the vehicle inner power storage unit 131 and the vehicle outer power storage unit 132 can be independent. Therefore, the lock can be released smoothly.

Also, at the time of a power failure, the actuator 14 is demagnetized in the same manner as the arrival of the unlock signal, so that the lock can be released without waiting for the arrival of the unlock signal.

<Recovery action>

When the door is closed, such as when the vehicle starts to travel, the manual door release device 100 performs a restoring operation.

In addition, due to the unlocking operation, the spring 153 contracts, and elastic force is accumulated in the spring 153 . At this time, the spring 68 accumulates an elastic force in balance with the elastic force of the spring 153 .

In the restoring operation, first, the unlocked state of the latch or the like for the handle of the operation unit 120 is released. Then, the rope 123 returns to the original position. Following this operation, the block 2 moves in the +X direction by the elastic force accumulated in the spring 153 by the unlocking operation. Therefore, the cylinder 6 is similarly moved in the +X direction by the elastic force of the spring 68, and returns to the original position together with the rope 123.

Then, when the actuator 14 is excited by an upper-level command, the actuator rod 14a is extended in the +X direction and comes into contact with the rollers 13a and 13b. Thereby, the rollers 13a and 13b can be rotated so as to be separated from each other in the Z direction. Therefore, the claws 11b and 12b of the latch levers 11 and 12 can be hooked to the grooves 152a and 152b of the block 2, and the initial state of the EVAC can be restored.

In this way, the return operation can be performed only by returning the handle of the operation unit 120 and performing the excitation operation of the actuator 14 . Therefore, even when the door lock is released in an emergency, it can be restored quickly.

According to the manual door releasing device 100 of the present embodiment, the unlocking unit 150 for releasing the locking mechanism 110 is actuated and unlocked by the operation force accumulated by the power storage unit 130 by the emergency operation. Therefore, since the operation force can be absorbed by the force accumulating portion 130, even if the operation portion 120 is pulled with a strong force, the unlocking portion 150 is not damaged.

In addition, when the lock of the actuator 14 is released, the unlocking part 150 is actuated by the operation force stored in the force accumulating part 130 to perform unlocking. Therefore, the operator does not need to perform operations other than the handle operation (lever operation) of the operation unit 120 separately.

In addition, after a passenger or the like operates the operation unit 120, it is possible to determine whether or not the unlocking is possible using the upper-level restricting unit 140. Therefore, it is possible to select the door to be unlocked after the crew, the station attendant, the train command unit, etc. have judged whether or not the lock can be unlocked. Thereby, the improvement of safety can be aimed at.

In fact, it is a general passenger who manually unlocks the door leaf 10 , and such unlocking operation is performed during an emergency. Therefore, it is desirable that the unlocking operation of the door leaf 10 is simple and has fewer steps, so that passengers can grasp it intuitively.

In the manual door release device 100 in the present embodiment, the two-stage operation of signal sending and unlocking, which is required in the conventional technology, is not required. In the manual door release device 100 of the present embodiment, the problem that it takes time until the door leaf is opened as in the conventional configuration can be solved. In addition, in the manual door release device 100 of the present embodiment, it is possible to solve the problem that the door cannot be opened unless the two-step operation is performed.

Moreover, in the manual door release apparatus 100 of this embodiment, the problem that the signal which notifies an occupant may not be output at the time of an emergency evacuation like the conventional structure can be solved. This problem arises from the fact that the lever is locked by the actuator so that the operation cannot be performed while the vehicle is running.

In addition, in the manual door release device 100 of the present embodiment, it is possible to solve the necessity of performing the unlocking operation from both sides of the vehicle inner side and the vehicle outer side, and to independently perform the unlocking operation from the vehicle inner side and the vehicle outer side both independently and reliably. The need for action.

Furthermore, according to the manual door release device 100 of the present embodiment, the two operations of signal transmission and unlocking are not required, the time until the door is opened can be shortened, and reliability and safety can be improved.

In the manual door release device 100 of the present embodiment, the power accumulating unit 130 includes a restricting unit 140 that restricts the transmission of a predetermined amount of operating force to the unlocking unit 150 , and when a release signal is received, the restricting unit 140 is driven to release the restriction. Then, a predetermined amount of operating force is allowed to be transmitted to the unlocking portion 150 , and the locking of the locking mechanism 110 is released. Thereby, it can be set as the stage in which the determination of whether or not to unlock is performed. Therefore, safety can be improved.

The operation unit 120 includes a vehicle inner side operation unit 121 that can be operated from inside the vehicle, and a vehicle outer side operation unit 122 that can be operated from outside the vehicle. The power accumulating portion 130 includes a vehicle inner power accumulating portion 131 for accumulating an operation force for operating the vehicle inner operating portion 121 , and a vehicle outer power accumulating portion 132 for accumulating an operating force for operating the vehicle outside operating portion 122 . Thereby, the unlocking of the door leaf 10 can be independently operated from either the inside of the vehicle or the outside of the vehicle.

The unlocking portion 150 includes a cylinder 151 and a piston 152 . The piston 152 is connected so as to transmit the output of the vehicle inner power storage unit 131 and the output of the vehicle outer power storage unit 132 . Thereby, the operation inside the vehicle and the operation outside the vehicle can be independently charged, and the lock can be released without interfering with each other.

The unlocking portion 150 has the link portions 62 and 72 as a synchronization mechanism for synchronizing the transmitted motion of the piston 151 caused by the output of the vehicle inner power storage portion 131 and the motion of the piston 151 caused by the output of the vehicle outer power storage portion 132 . . Thereby, operations inside and outside the vehicle do not interfere with each other, and the operation reliability of the manual door release device 100 in an emergency can be improved, thereby improving safety.

The force accumulating unit 130 can store the operation force by the urging force of the springs 68 and 78 . Thereby, the accumulating force for accumulating the operation force can be set by adjusting the urging forces of the springs 68 and 78, and a driving power source or the like can be eliminated.

The unlocking portion 150 includes a cylinder 151 and a piston 152 . Further, a spring 153 that returns the position of the piston 151 and the positions of the springs 68 and 78 of the power accumulating unit 130 to the position before power accumulating is provided. Thereby, a quick recovery operation can be performed.

The restricting portion 140 includes latch levers 11 and 12 that restrict transmission of the operating force accumulated by the force accumulating portion 130 to the unlocking portion 150 , and an actuator 14 that drives the latch levers 11 and 12 to release the operation force to the unlocking portion 150 . delivery restrictions. Thereby, unlocking/locking can be performed easily.

The unlocking portion 150 includes a cylinder 151 and a piston 152 . Hooked parts (grooves) 152a and 152b are formed in the piston 152 . At one end of the latch levers 11 and 12, claws (hook parts) 11b and 12b which can be hooked to the grooves (hook parts) 152a and 152b are formed. Thereby, the reliability of preventing malfunction can be improved.

Rollers 13a and 13b are provided at the other ends of the latch levers 11 and 12 . The rollers 13a and 13b are rotated by the actuator rods 14a of the actuator 14 which are in contact with the rollers 13a and 13b, thereby releasing the restriction on the transmission of the operation force stored in the force accumulating unit 130 to the unlocking unit 150 . Thereby, the ease of movement when the actuator rod 14a of the actuator 14 is brought into contact with the rollers 13a and 13b can be improved, and the size of the actuator 14 can be reduced.

The piston 152 has a groove (first hooked portion) 152a and a groove (second hooked portion) 152b. At one end of each of the pair of latch levers 11 and 12, a pair of pawls (first hooking portions) 11b and pawls (second 2 hook part) 12b. At the other ends of the pair of latch levers, rollers 13a, 13a, 13a, 13b.

Accordingly, the movement of the latch levers 11 and 12 can be smoothed, the ease of movement when the actuator lever 14a of the actuator 14 is in contact with the rollers 13a and 13b can be improved, and the movement to the unlocking portion 150 can be transmitted smoothly.

Detection units 161 to 164 are provided which detect the accumulation of the operation force in the force accumulating unit 130 by the operation of the operation unit 120 . Thereby, based on the detection results of the detection units 161 to 164 , it is possible to determine whether or not the unlocking is possible by the restricting unit 140 , which is the upper level. Therefore, it is possible to judge whether or not the lock can be released by a crew member, a station crew member, a train command unit, or the like.

(Second Embodiment)

Hereinafter, 2nd Embodiment of the manual door release apparatus of this invention is demonstrated based on drawing.

FIG. 6 is a schematic diagram showing the manual door release device of the present embodiment. FIG. 7 is a view of FIG. 6 viewed from the axial direction.

The present embodiment differs from the above-described first embodiment in terms of the number of power accumulators, and other components corresponding to the above-described first embodiment are denoted by the same reference numerals and Its description is omitted.

However, in the following description, the structure "corresponding" to the structure of 1st Embodiment is a structure corresponding to the operation|movement, such as an unlocking operation, and the shape etc. may differ from each other.

In the present embodiment, the power storage portion 130 includes only one power storage portion 230 corresponding to the vehicle inner power storage portion 131 , for example, the vehicle outer power storage portion 132 is not provided.

In the manual door release device 200 of the present embodiment, as shown in FIG. 6 , the spring 268 corresponding to the spring 68 of the vehicle inner power accumulating portion 131 and the spring 253 corresponding to the spring 153 performing the restoring operation are arranged in a straight line shape.

In addition, as a structure corresponding to the block 2, a cylindrical cylinder 202 is provided. The cylinder 202 is coaxially accommodated in a cylindrical cylinder 251 formed in the base 205 as a structure corresponding to the base 5 . A rod 203 corresponding to the rod 3 is arranged coaxially inside the cylinder 202 . And the rod 203 extended in the −X direction is coaxially arranged inside the cylindrical cylinder 251 of the base 205 .

An end portion 201b corresponding to the end portion 1b of the connecting rod 1 is connected to the end portion in the +X direction of the cylinder 202 . The end portion 201b is formed with a protruding portion 211b corresponding to the claw 11b serving as the hook portion of the restricting portion 140 . The protruding portion 211b is hooked on the latch 252a corresponding to the groove 152a serving as the hooked portion. The latch 252a is driven to disengage from the protruding portion 211b by the actuator 214 of the restricting portion 140 corresponding to the actuator 14 .

And the rod 203 is arrange|positioned coaxially to the cylinder 251 formed in the base 205. The portion extending in the −X direction of the rod 203 is the rod 265 corresponding to the cylinder end portion 65 . The rope fixing part 266 corresponding to the rope fixing part 66 is connected to the rod 265 so as to extend in the -X direction at the -X direction end. The cord fixing portion 266 is connected to the operation portion 120 via the cord (cable) 123 .

Inside the cylinder 251 formed in the base 205, the cylinder 202 is coaxially arranged so as to be movable in the X direction. In the cylinder 202 , the rod 203 penetrates the −X direction end portion of the cylinder 202 . An enlarged diameter portion 252 corresponding to the piston 152 is formed on the rod 203 so as to be in contact with an end portion in the −X direction of the cylinder 202 . A spring 268 corresponding to the spring 68 is coaxially arranged in a portion of the inside of the cylinder 202 that is positioned on the +X direction side relative to the −X direction end portion of the cylinder 202 .

An enlarged diameter end portion 206 corresponding to the cylinder 6 is connected to an end portion in the +X direction of the rod 203 . The enlarged diameter end portion 206 reciprocates in the X direction inside the cylinder 202 . In the −X direction of the enlarged diameter end portion 206 , the +X direction end portion of the spring 268 is in contact with each other. In the −X direction of the enlarged diameter portion 252 , a spring 253 is arranged, and the spring 253 is in contact with an end portion in the −X direction of the cylinder 251 .

The spring 253 and the spring 268 are in contact with the enlarged diameter portion 252 so that the pressing force is reversed. The elastic restoring force of the spring 268 is stronger than the elastic restoring force of the spring 253 . Specifically, it is preferable that the coil diameter or wire diameter of the spring 268 is larger than that of the spring 253, and the elastic force is larger.

In the restricting part 140, the actuator 214 is arrange|positioned so that the actuator rod 214a may move in a Y direction. As shown in Figure 7, the actuator rod 214a drives the latch 252a via the links 214b, 214c. In addition, the actuator lever 214a is in the locked state at the retracted position, and is unlocked by being driven in the extending direction.

＜Normal state＞

Also in the manual door release device 200 of the present embodiment, the locking mechanism 110 locks the door leaf 10 in a normal state such as vehicle running. At the same time, the actuator 214 is set so that it cannot be unlocked, and as shown in FIGS. 6 and 7 , the actuator lever 214a is in the retracted position. The protrusion 211b is hooked to the latch 252a. The cylinder 202 and the link 1 are restricted from moving relative to the base 205 .

＜Unlocking action＞

8 and 9 are schematic views showing the manual door release device 200 according to the present embodiment. FIG. 10 is a view of FIG. 9 viewed from the axial direction.

In the manual door release device 200 of the present embodiment, for example, in an emergency, the operation unit 120, which is a handle or the like, is operated. Then, as shown in FIG. 8 , the manual door release device 200 pulls the rope fixing portion 266 , the rod 265 , the enlarged diameter portion 252 , the rod 203 , and the enlarged diameter end portion 206 in the −X direction as one body via the rope 123 .

Here, when the operation unit 120 cannot be unlocked (the vehicle is running, or the vehicle cannot get on or off due to the door on the opposite side of the platform), the actuator lever 214a is located at the retracted position and restricts the movement of the protrusion 211b. The protruding portion 211b is hooked on the latch 252a, and restricts the movement of the cylinder 202 integrated with the end portion 201b. Therefore, the cylinder 202 maintains the same position with respect to the base 205 as before the operation part 120 is operated.

The -X direction end portion of the cylinder 202 does not move together with the cylinder 202, and therefore maintains the position in the X direction. Therefore, as shown in FIG. 8, due to the stroke of the enlarged diameter end portion 206, the spring 268 contracts. Due to the stroke of the enlarged diameter end portion 206 , the operating force is accumulated in the spring 268 .

When unlocking in an emergency, first, the handle of the operation part 120 is held in the pulled position, and the elastic force (operation force) of the spring 268 is stored in the force accumulating part 230 (130).

At this time, although not shown, the rope fixing portion 266 pushes the switch to issue a signal for requesting unlocking. The signal is transmitted to the superiors who control the vehicle, such as the flight attendant and the operation control room, and are required to judge whether the lock can be released or not.

When it is determined at the upper level (vehicle, ATC) that unlocking is possible (vehicle stop, platform side entrance 105 ), the actuator 214 of the restricting unit 140 is demagnetized by the unlock signal issued by the upper level command. As a result, the actuator rod 214a moves in the +Y direction to take the extended position. In addition, when emergency evacuation is required, such as when an emergency occurs, or when a power failure occurs, the actuator 214 is similarly demagnetized.

The actuator rod 214a moved in the +Y direction to be in the extended position drives the latch 252a, and the protrusion 211b is in a disengaged state. Thereby, the protrusion part 211b can be separated from the latch 252a, and the movement of the cylinder 202 integrated with the end part 201b becomes an unrestricted state which is not restricted. Therefore, the cylinder 202 can move relative to the base 205 from the position before the operation part 120 is operated. That is, the cylinder 202 can move in the X direction relative to the base 205 .

Then, as shown in FIGS. 9 and 10 , the cylinder 202 is moved in the −X direction by the elastic force (operation force) accumulated by the contracted spring 268 . At this time, the rod 203 is not moved relative to the base 5 . When the cylinder 202 is moved in the -X direction by the elastic force (operation force) of the spring 268, the link 1 also moves in the -X direction.

Thereby, the locking of the door leaf 10 by the locking mechanism 110 is released due to the movement of the link 1 .

In addition, the spring 253 is contracted by the unlocking operation, and elastic force is accumulated in the spring 253 . At this time, the spring 268 accumulates an elastic force in balance with the elastic force of the spring 253 .

<Recovery action>

When the door is closed, such as when the vehicle starts to travel, the manual door release device 200 performs a restoring operation.

In the restoring operation, first, the unlocked state of the latch or the like for the handle of the operation unit 120 is released. Then, the rope 123 returns to the original position. Following this operation, the enlarged diameter portion 252 moves in the +X direction by the elastic force accumulated in the spring 253 by the unlocking operation.

At this time, the rope fixing portion 266 , the rod 265 , the rod 203 , and the enlarged diameter end portion 206 integrally move in the +X direction. At the same time, the cylinder 202 is pressed by the enlarged diameter portion 252 and the enlarged diameter end portion 206, and also moves in the +X direction. The rope fixing portion 266 and the rod 265 also move in the X direction by the elastic force of the spring 253 , and return to their original positions together with the rope 123 .

Since the unlocking portion can be actuated by the operating force accumulated by the power accumulating portion by the emergency operation, the operator does not need to perform two-stage operations. At the same time, the upper-level restricting unit can determine whether or not the lock can be unlocked. Therefore, the door can be selected after the crew, station attendant, train command unit, etc. have judged whether or not the lock can be unlocked.

Thereby, the improvement of safety can be aimed at. Since the operation force can be absorbed by the force accumulating portion, even if the operation portion is pulled with a strong force, the unlocking portion is not damaged.

The force accumulating portion includes a restricting portion that restricts the transmission of a predetermined amount of operating force to the unlocking portion. When a release signal is received, the restriction is released by driving the restricting portion, allowing a predetermined amount of operating force to be transmitted to the unlocking portion, thereby releasing the locking of the locking mechanism.

As a result, it is possible to determine whether or not to unlock, so that safety can be improved.

The operation portion includes a vehicle-inside operation portion that can be operated from inside the vehicle and a vehicle-side operation portion that can be operated from outside the vehicle.

Thereby, the door lock release can be independently operated from either the inside or the outside of the vehicle.

The unlocking portion includes a cylinder and a piston. The piston is connected so as to transmit the output of the vehicle inner power storage unit and the output of the vehicle outer power storage unit.

Thereby, the operation force can be accumulated independently for the operation inside the vehicle and the operation outside the vehicle, and the lock can be released without interfering with each other.

The unlocking portion has a synchronization mechanism for synchronizing the transmitted movement of the piston caused by the output of the vehicle inner power storage portion and the movement of the piston caused by the output of the vehicle outer power storage portion.

As a result, operations inside the vehicle and outside the vehicle do not interfere with each other, and it is possible to improve the reliability of operations in an emergency, and to improve safety.

The force accumulating unit can store the operating force by the urging force of the spring.

Thereby, it is possible to set the accumulating force for accumulating the operating force, and it is possible to eliminate the need for a driving power source or the like.

The unlocking portion includes a cylinder and a piston. A spring is provided for returning the position of the piston and the position of the spring of the accumulating portion to the position before the accumulating.

Thereby, a quick recovery operation can be performed.

The restricting portion includes a latch lever that restricts transmission of the force accumulated by the force accumulating portion to the unlocking portion, and an actuator that drives the latch lever to release the transmission to the unlocking portion limit.

Thereby, the movement of the latch lever can be smoothed, the ease of movement when the actuator and the roller are brought into contact can be improved, and the transmission of the movement to the unlocking portion can be smoothed.

A detection unit that detects the accumulation of an operating force in the power accumulating unit by the operation of the operating unit is provided. Thereby, based on the detection result of the detection unit, it is possible to determine whether or not the unlocking is possible by the upper-level restricting unit. Therefore, it is possible to judge whether or not the lock can be released by a crew member, a station crew member, a train command unit, or the like.

The manual door release apparatus of this invention can select each structure of the above-mentioned embodiment suitably, and can apply it in combination. Furthermore, each configuration of the above-described embodiment can be appropriately changed.

For example, the force accumulating portion 130 may be charged by an elastic member other than the springs 68 and 78 . For example, air can be used as the elastic member. In this case, the cylinders 6 and 7 of the force accumulating unit 130 are considered to have high airtightness, and the ends in the −X direction of the rods 3 and 4 function as pistons. Alternatively, as the elastic member, a structure having high elasticity such as rubber is also considered.

For example, instead of the rope fixing parts 66 and 76 via the ropes 123 and 124, the operation part 120 and the power storage part 130 may be rigidly connected. When the ropes 123 and 124 are used, the degree of freedom of arrangement of the operation part 120 with respect to the power storage part 130 can be improved.

In addition, when the operation force accumulated in the power accumulating portion 130 becomes a certain value or more, it may be transmitted to the unlocking portion 150 so that the locking and unlocking can be performed. In this case, a configuration in which the restricting portion 140 is not provided can be adopted.

Furthermore, the operation unit 120 may not include both the vehicle inner side operation unit 121 and the vehicle outer side operation unit 122 . In this case, only one of the vehicle inner side operation portion 121 and the vehicle outer side operation portion 122 can be arranged.

Further, the actuator 14 of the unlocking portion 140 may be configured to be capable of advancing and retracting the actuator rod 14a in directions other than the −X direction. In this case, it is preferable that the rotation axis of the rollers 13a and 13b is also changed according to the advancing and retracting direction of the actuator rod 14a.

Furthermore, in the manual door release device 200 of the second embodiment, the groove (first hooked portion) 152a and the groove (second hooked portion) 152b are provided in the cylinder 202 as in the unlocking portion 140 of the first embodiment. . A pair of pawls (first hooking portions) 11b and pawls (second hooking portions) 12b that can be hooked on the grooves 152a and the grooves 152b are provided on the base 5 so as to be rotatable by the rotation shafts 11a and 12a. Latch levers 11, 12. Rollers 13a and 13b are provided at the ends (other ends) in the −X direction of the latch levers 11 and 12 . The rollers 13a and 13b are arranged so as to be able to contact the actuator rod 14a so as to sandwich the actuator rod 14a.

A structure like this is also possible. In this case, the actuator 214 can reciprocate the actuator rod 14a in the X direction.

Further, the manual door release device can be arranged to be rotated by an arbitrary angle around the X-direction axis. The arrangement direction is not particularly limited as long as the direction of the lever 1 connected to the lock mechanism 110 corresponds to the direction required for driving the lock mechanism 110 .
