The present invention also relates to a door unlocking device for unlocking the door body and a method of unlocking the door body locked by the lock mechanism in an emergency.

The door device of a railroad vehicle is provided with a door body and a lock mechanism for locking the door body in a closed state. While the vehicle body is running, the door device is designed to ensure the safety of passengers so that the door body is not locked by the lock mechanism and unexpectedly opened. The following methods are known as a method for passengers to open such a locked door body in an emergency.

First, when the power supply to the vehicle is normal, the passenger sends a request signal requesting the unlocking of the door body to the crew members in the driver's seat, etc. by pressing a button or the like provided near the door body. .. Then, after the crew confirms that the door body can be opened, the passenger mechanically unlocks the door body by using a lever or the like provided near the door body. The reason for getting the crew's confirmation before unlocking the door body in this way is that the vehicle body is generally running when the power supply is normal, so the speed of the vehicle body before unlocking the door body This is because it is necessary to ensure the safety of passengers by confirming that the speed is below a certain level. In this case, the lever for unlocking the door body cannot be operated until the confirmation of the crew is obtained.

On the other hand, if there is an abnormality in the power supply for opening the door body, the vehicle is generally stopped. Therefore, it is not necessary to perform the above-mentioned confirmation work, and the passenger can unlock the door body only by operating the lever.

Alternatively, the lever described above may send a request signal requesting unlocking of the door body as well as the unlocking operation of the door body. In this case, the lever is operated in two stages, and if the power supply is normal, the lever can only be operated up to the first stage until the confirmation of the crew is obtained. Then, when the power supply is normal, the passenger sends a request signal requesting the unlocking of the door body by operating the lever up to the first stage, and after the confirmation of the crew is obtained, the lever is moved to the first stage. Operate up to 2 steps to unlock the door body. On the other hand, when there is an abnormality in the power supply, the passenger operates the lever at once up to the second stage to unlock the door body.

The first condition is that it is detected from the measurement result by the speed sensor 26 that the vehicle body 25 is stopped or the speed of the vehicle body 25 is equal to or less than a predetermined speed. The second condition is that the timer 215 is activated and a predetermined time has elapsed. Of course, the determination unit 212 may determine that the door body 50 can be opened when either the first condition or the second condition is satisfied.

Further, instead of providing the determination unit 212, the occupant may determine whether or not the door body 50 can be opened based on the speed sensor 26, the timer 215, and other instruments.

The switch unit 213 is switched to supply electric power from the power supply 40 to the motor 35 only when the determination unit 212 determines that the door body 50 can be opened. Of course, the switch unit 213 may be switched at the discretion of the occupant.

Next, the lock mechanism 60 of the present embodiment will be described with reference to FIGS. 6 to 8. FIG. 6 is a plan view showing the lock mechanism 60 in the unlocked state, and FIG. 7 is a plan view showing the lock mechanism 60 in the locked state. Further, FIG. 8 is a side view showing the lock mechanism 60 in the locked state. In the example shown in FIGS. 6 to 8, the door body 50 has a pair of draw-type left and right door panels 50A and 50B.

As shown in FIG. 8, the lock mechanism 60 is supported by a substrate 5 fixed to the vehicle body 25 above the door body 50. The substrate 5 extends along the opening / closing direction of the door body 50. As shown in FIGS. 6 to 8, the lock mechanism 60 includes a link mechanism 61 that can be deformed into a linear state and a bent state in a horizontal plane, and a link holding mechanism 65 that operates in a horizontal plane. The link mechanism 61 is formed by connecting three links 62a, 62b, 62c. The central link 62a is rotatably fixed to the substrate 5 by a connecting pin 63a at the central portion in the longitudinal direction thereof. One end of the link 62b is connected to one end of the central link 62a by a connecting pin 63b. Further, one end of the link 62c is connected to the other end of the link 62a by a guide connecting pin 63c. Pins 63d and 63e are provided at the ends of the link 62b and the link 62c on the opposite side of the connection point with the link 62a, respectively.

Further, the lock mechanism 60 has a lock slider 30 which is a movable member for switching the lock mechanism 60 between the locked state and the unlocked state. The lock slider 30 is supported by the substrate 5 and can slide along the opening / closing direction of the door body 50. The lock slider 30 slides by receiving a driving force from the motor 35. As shown in FIG. 8, one end of the wire 31 is connected to one end of the lock slider 30, and the slide can be slid by the tensile force from the wire 31.

As shown in FIGS. 6 to 8, the pins 63d and 63e located at the ends of the link mechanism 61 are the guide grooves 80A and 80B formed in a linear shape parallel to the moving direction of the lock slider 30 on the substrate 5, respectively. An end portion is inserted into (indicated by a two-dot chain line in FIGS. 6 and 7), and the guide groove 80A and 80B are movably installed. That is, the movements of the pins 63d and 63e are regulated by the guide grooves 80A and 80B, respectively.

Further, the end portion of the link mechanism 61 on the lock slider 30 side of the guide connecting pin 63c is inserted into the slit 30e of the lock slider 30. Therefore, the position of the guide connecting pin 63c is restricted by the position of the lock slider 30. From this, it becomes possible to switch between the linear state and the bent state of the link mechanism 61 by moving the lock slider 30.

The link holding mechanism 65 is a pair of engaging members 66A, which are rotatably installed in a horizontal plane in the vicinity of both ends of the link mechanism 61, symmetrically with respect to the link mechanism 61 (relative to the connecting pin 63a). It is configured to include 66B and a connecting spring 69 that connects the pair of engaging members to each other. The engaging members 66A and 66B are provided with first engaging portions 67A and 67B and second engaging portions 68A and 68B formed in a concave shape on their peripheral edges, respectively, and the engaging members 66A and 66B are provided with the engaging members 66A and 66B, respectively. The rotating shafts 81A and 81B are fixedly installed with respect to the substrate 5 (see FIG. 8). A hanging member 82 is fixed to the pair of rotating shafts 81A and 81B, and the connecting pin 63a for rotatably fixing the link 62a at the center of the link mechanism 61 is the hanging member. Supported by 82.

In the link holding mechanism 65, the engaging members 66A and 66B receive a force from the connecting spring 69 and are held in the state shown in FIG. 6 in a state where no external force is received. At this time, the engaging members 66A and 66B restrain the movement of the link mechanism 61 extending in a linear state by the outer edge portion (the portion indicated by the arrow P1 in FIG. 6). As described above, when the link mechanism 61 is held in the bent state by the engaging members 66A and 66B, the lock slider 30 is locked in the locking direction (arrows in FIG. 6) via the slit 30e and the guide connecting pin 63c. The movement in the direction indicated by) will be restricted.

On the other hand, in the engaging members 66A and 66B, the lock pins 55A and 55B fixed to the door panels 50A and 50B move in the closing direction (direction indicated by the arrow in FIG. 5), whereby the first engaging portion is formed. The edges of 67A and 67B (the portion indicated by P2 in FIG. 6) are urged, and the second engaging portions 68A and 68B are brought closer to the link mechanism 61 against the urging force of the connecting spring 69 (arrow R1 in FIG. 6). It is formed so that it can rotate in the direction indicated by. When the door panels 50A and 50B are in the fully closed position, as shown in FIG. 7, the lock pins 55A and 55B are engaged with the first engaging portions 67A and 67B, and the second engaging portions 68A and 68B are engaged. The position is a position where it can engage with the pins 63d and 63e located at the end of the link mechanism 61. That is, the engaging members 66A and 66B shift to a state in which the deformation of the link mechanism 61 is not restrained. At this time, if the lock slider 30 moves in the locking direction, the guide connecting pin 63c moves along the slit 30e, so that the link mechanism 61 shifts from the bent state to the linear state. Then, the pins 63d and 63e located at the end of the link mechanism 61 engage with the second engaging portions 68A and 68B of the engaging members 66A and 66B. As a result, the rotation of the engaging members 66A and 66B is restrained. Therefore, the movement of the lock pins 55A and 55B in the opening direction (indicated by the arrow in FIG. 7) is restricted by the first engaging portions 67A and 67B.

Next, the operation of the railroad vehicle 10 having the door device 20 of the present embodiment will be described.

First, when the operator tries to open the door body 50, the door body 50 is locked in a closed state by the lock mechanism 60. That is, the link mechanism 61 of the lock mechanism 60 is in the linear state shown in FIG. 7. Further, the operation member 230 of the door unlocking device 200 is located at the non-operation position A shown in FIGS. 2 and 3. Further, the switch unit 213 is switched to a position where the power supply from the power supply 40 to the motor 35 of the lock mechanism 60 is cut off.

First, a case where the power supply from the power source 40 to the vehicle 10 is normal when the operator starts the operation of the operation member 230 will be described. In this case, the solenoid actuator 281 of the clutch mechanism 280 of the door unlocking device 200 is excited by the power supply from the power supply 40. Therefore, the movable portion 283 of the clutch mechanism 280 remains housed in the main body portion 282 and is not engaged with the operating member 230. Therefore, even if the operator operates the operation member 230, the operation of the operation member 230 is not transmitted to the transmission means 270.

In such a state, in order to unlock the door body 50 locked in a state closed by the lock mechanism 60, the operator moves the operation member 230 of the door unlocking device 200 from the non-operation position A to the operation position B. Move towards. When the operation member 230 is moved, the operation of the operation member 230 is detected by the operation detection sensor 260. When the operating member 230 is moved to the operating position B, an electric signal is transmitted by the door detection sensor 260.

The operation member 230 moved to the operation position B is held by the holding mechanism 235 of the door unlocking device 200. As a result, the operating member 230 is maintained at the operating position B without returning to the non-operating position A.

When the determination unit 212 receives an electric signal from the motion detection sensor 260, the determination unit 212 activates the timer 215 to determine whether the door body 50 can be opened. Specifically, the determination unit 212 confirms that the vehicle body 25 is stopped or the speed of the vehicle body 25 is detected to be less than or less than a predetermined speed from the measurement result of the speed sensor 26. (First condition). Further, the determination unit 212 confirms that a predetermined time has elapsed after the operation member 230 has been operated, that is, the timer 215 has been activated and the predetermined time has elapsed (second condition). Then, after confirming that the first condition and the second condition are satisfied, the determination unit 212 determines that the door body 50 can be opened. By the time the timer 215 is activated and a predetermined time elapses, the vehicle body 25 may be moved to a place suitable for the occupant to get off.

When the determination unit 212 determines that the door body 50 can be opened, the switch unit 213 is switched and power is supplied to the motor 35 of the lock mechanism 60 from the power supply 40.

Next, after the operator starts the operation of the operation member 230, specifically, until the operator moves the operation member 230 from the non-operation position A to the second operation position C, or until the second operation position C A case where an abnormality occurs in the power supply 40 of the vehicle 10 after moving to the above will be described.

In this case, the solenoid actuator 281 of the clutch mechanism 280 shifts from the excited state to the degaussed state due to the occurrence of an abnormality in the power supply 40. As a result, the movable portion 283 housed in the main body portion operates with respect to the main body portion 282 and protrudes from the main body portion 282. When the operating member 230 is moved to the second operating position C, the movable portion 283 protruding from the main body portion 282 (in the second operating position C when the operating member 230 is moved to the second operating position C). , It is received by the second receiving portion 283b of the operating member 230 and engages with the operating member 230.

In this state, when the operator further moves the operation member 230 toward the third operation position D, the operation of the operation member 230 is transmitted to the transmission means 270 by the clutch mechanism 280. As a result, the wire 31 connected to the rack 273 of the clutch mechanism 280 is pulled downward. When the wire 31 is pulled downward, the lock slider 30 of the lock mechanism 60 slides in the unlocking direction, and the lock mechanism 60 unlocks the door body 50. The movement of the operating member 230 from the second operating position C to the third operating position D is not hindered because the portion 238 provided with the strength reducing configuration of the casing 236 deforms when it comes into contact with the operating member 230.
