It is characterized by

[0008]

[Action]

 With the above structure, according to the present invention, when moving in and out, the operation rod provided on the back side of the chassis of the parking cage so as to be able to move forward and backward is pushed by the pushing means provided on the fixed side of the vehicle entry position to move the inside of the chassis. When the vehicle is retracted, the door-opening prevention frame, which is erected on the side of the chassis of the parking cage, is collapsed to allow the door of the vehicle to be opened. In this collapsed state, when the passenger enters the parking cage, the passenger opens the door of the vehicle and exits.On the other hand, when the passenger exits the vehicle, the passenger opens the door and enters the vehicle. The pushing motion is released and the actuating rod moves forward to the outside of the chassis, and the door-opening prevention frame is erected to prevent the door of the mounted vehicle from opening.

In this standing state, a retroreflective photoelectric switch provided on the fixed side of the vehicle entry position projects light onto a retroreflective mirror provided on the door-opening prevention frame, and the retroreflective mirror returns. When the reflected light reflected by the photoelectric switch is received, it can be seen that the door-opening prevention frame does not interfere with the door of the vehicle and completely stands up and the door is completely closed. On the other hand, when the light emitted from the photoelectric switch is reflected by the side of the parking cage or the vehicle body without being retroreflected by the retroreflector, the optical axis of the incident light is tilted with respect to the normal line of the reflective surface of the retroreflector. Therefore, the reflected light is reflected at the opposite side of the normal line with a reflection angle equal to the incident angle, this reflected light is not received by the photoelectric switch, and the door-opening prevention frame interferes with the vehicle door. It can be seen that the standing state is insufficient and the door is half open.

Therefore, in order to determine the half-opened state of the door, it is not necessary to block the light projection by the shield plate, and the number of parts is reduced and the mounting work is simplified because the shield plate is not used.

It penetrates through the sliding hole and moves forward toward the front of the chassis 11 to project.

Further, the operating rod 21 is constantly urged forward by the coil spring 22 so as to project to the front of the chassis 11, and the operating rod 21 normally projects the door blocking frame 14 to the outside of the chassis 11. While it is moved forward (see FIG. 8) to stand up, it is retracted to the inside of the chassis 11 (see FIG. 9) at the time of loading and unloading to lie down. That is, the door-opening prevention frame body 14 always keeps the upright posture by the spring force of the coil spring 22, and if necessary, moves the operating rod 21 backwards against the spring force of the coil spring 22 and falls down. It is designed to let you.

As shown in FIG. 3, bending tubes 25, 26 are mounted on the rear surfaces of the wheel mounting portions 11a, 11b of the chassis 11 and are attached to the drain holes 24, 24 with their ends oriented horizontally. One ends of the hoses 27 and 28 are connected to the bending tubes 25 and 26, respectively, and the other ends of the hoses 27 and 28 are connected to connecting shafts 29 extending in a direction orthogonal to the respective ends. As shown in FIGS. 8 and 9, the connecting shaft 29 is rotatably connected to the second arm portion 20b of the arm 20 by a link 30, and the ends of the hoses 27 and 28 are normally drain holes 24 and. Although it is located above 24, it is located below the drain holes 24, 24 when the operating rod 21 is pushed by a pushing device 32, which will be described later, for example, in a snow country. The water accumulated in the storage portions 11a and 11b is discharged into the pit 31.

On the fixed side (pit 31) of the vehicle entry position 10 of the parking section 8, a pushing device 32 as a pushing means faces the operating rod 21 of the parking cage 6 located at the vehicle entry position 10. It is installed to do. As shown in FIGS. 6 and 7, the pushing device 32 includes a motor 34 with a reduction gear installed on a base 33, and a drive shaft 34 a of the motor 34 has a pinion meshing with a rack 35. 36 is fixed, and a pushing plate 37 is attached to the tip of the rack 35 via coil springs 38, 38 as a buffer mechanism. In this case, when a certain load or more is applied to the push plate 37, the motor 34 is stopped by the operation of the limit switch LS1 and the movement of the rack 35 is stopped. Guide rods 39 and 40 are disposed on the base 33 so as to be horizontally movable by support members 41 and 41, and the tip ends of the guide rods 39 and 40 are connected to the push plate 37. The pushing plate 37 is designed to move horizontally. LS2 and LS3 are limit switches for restricting the forward stroke and the backward stroke of the push plate 37, and 42 is its operating piece. When each of the parking cages 6 moves to the vehicle loading position 10, that is, at the time of loading / unloading, the push plate 37 is moved forward by the drive of the motor 34, and the actuating rod 21 is pushed by the push plate 37. The vehicle body 11 is retracted inward to prevent the door 14 from opening.

As shown in FIGS. 3 and 4, a regression mirror 43 is attached to the leg portion 16 b of the front turning leg 16 of the door opening prevention frame body 14, while the parking portion 8 is mounted on the vehicle. A retroreflective photoelectric switch 44 is arranged on the fixed side (pit 31) of the entry position 10, and as a feature of the present invention, as shown in FIG. 10, the photoelectric switch 44 has an optical axis B of incident light. Is inclined by θ1 with respect to the normal A of the reflecting surface of the regression mirror 43. Therefore, when the light emitted from the photoelectric switch 44 is reflected by the retroreflective mirror 43, it returns to the photoelectric switch 44 as shown by the solid line in FIG. When the light is not reflected by 43 but reflected by the parking cage 6 or the vehicle C (vehicle body), as shown by the broken line in FIG. 10, the reflection angle θ2 is equal to the incident angle θ1, and the normal line A is set to the opposite side. The reflected light does not return to the photoelectric switch 44 and this reflected light is not detected by the photoelectric switch 44. Then, in the standing state of the door blocking frame 14, the photoelectric switch 44 projects the light to the retroreflective mirror 43, and the reflected light reflected back by the retroreflective mirror 43 is received to drive the parking device 2. Has been done. On the other hand, when the light emission from the photoelectric switch 44 does not return, it is considered that the standing-up state of the door-opening prevention frame 14 is insufficient and the parking device 2 cannot be operated and an alarm is issued. There is.

Therefore, the vehicle door opening accident prevention device 45 according to the embodiment of the present invention is configured by the door opening prevention frame body 14, the actuation rod 21, the pushing device 32, the return mirror 43, the photoelectric switch 44, and the like. There is.

Next, the operation of the vehicle door open accident prevention device 45 will be described.

First, when the parking cage 6 moves to the vehicle entry position 10 and stops, the motor 34 of the pushing device 32 is driven, the rack 35 moves forward by the rotation of the pinion 36, and the pushing plate 37 is parked. It projects toward the cage 6 and presses the operating rod 21 of the parking cage 6. As a result, the operating rod 21 retracts inwardly of the chassis 11 against the spring force of the coil spring 22, and the arm 20 rotates counterclockwise from the state of FIG. 8 to the state of FIG. Then, the open door blocking frame body 14 in the upright state falls down as shown by the two-dot chain line in FIG.

Next, in the collapsed state of the door-opening prevention frame 14, the driver opens the door c2 of the vehicle C to get in when leaving the vehicle, and drives the vehicle C to leave the vehicle. The transmigrant drives the vehicle C into the parking cage 6, then opens the door c2 and exits from the parking section 8.

In this case, since the door-opening prevention frame body 14 has fallen down, the door c2 of the vehicle C mounted in the parking cage 6 can be opened and closed freely, and the regressive reflecting mirror 43 is connected to the photoelectric switch 44. Since the projected light is not reflected, the parking device 2 does not operate, and the driver can safely enter and exit.

After that, when the parking cages 6 are circulated, when the pushing plate 37 is moved backward by driving the motor 34, the operating rod 21 is moved outward by the spring force of the coil spring 22. The arm 20 pivots in the clockwise direction from the state of FIG. 9 to the state of FIG. 8 and the door opening prevention frame body 14 stands up.

In this case, if the door c2 is forgotten to be closed, the door-opening prevention frame body 14 collides with the door c2 and the door-opening prevention frame body 14 cannot stand up any more. Since the light is emitted from the photoelectric switch 44, it is not received by the regressive reflecting mirror 43 because it is positioned below the position of, and the reflection angle θ2 is equal to the incident angle θ1 as shown by the broken line in FIG. Reflected by the vehicle C, the parking device 2 does not operate. Therefore, in this case, when the door-opening blocking frame body 14 is once laid down to completely close the door c2 of the vehicle C, and then the door-opening blocking frame body 14 is erected again, the photoelectric switch 44 emits light. The retroreflector 43 receives the light and the parking device 2 can be operated.

Therefore, the half-opened state of the door c2 can be surely determined without blocking the light projected from the photoelectric switch 44 by the shield plate, and the number of parts can be reduced by the amount that the shield plate is not used. In addition, the mounting work can be simplified.

[Effect of device]

 As described above, according to the present invention, a return reflecting mirror is provided on the open door blocking frame body that is foldable on the side of the chassis of the parking cage, while the return reflection mirror is provided on the fixed side of the parking section for the vehicle entry position. A photoelectric switch is installed so that the optical axis of the incident light is inclined with respect to the normal line of the reflecting surface of the above-mentioned retroreflective mirror, and only the reflected light reflected back by the retroreflective mirror is received. Without doing so, the half-opened state of the door can be reliably determined, the number of parts can be reduced correspondingly, and the mounting work can be simplified.
