When the pallet 11 moves forward and the dog 24 collides with the fall prevention piece 22, the stopper 25 prevents the fall prevention piece 22 from rotating forward, so that the pallet 11 does not fall into the lift space of the elevator. To be prevented. When the pallet 11 is taken out, the fall prevention release cylinder 26 pushes the fall prevention release piece 23 rearward to rotate the fall prevention piece 22 so that the dog 24 can pass forward.

[Problems to be solved by the device]

This fall prevention device prevents the dog 24 of the pallet 11 from passing in the retracted state of the pallet 11 so that the dog 24 of the pallet 11 can pass without colliding with the fall prevention piece 22 when the pallet 11 is transferred to the lift 12 of the elevator. Although the release prevention piece 22 must be rotated by pushing the fall prevention release piece 23 rearward with the release cylinder 26, the fall prevention piece 22 of the fall prevention device has conventionally been rectangular, so as shown in FIG. Inevitably, the distance L between the fall prevention piece 22 and the dog 24 in FIG. Therefore, when the pallet moves forward due to an earthquake or the like, a fall accident can be prevented, but there is a risk that the pallet 11 will protrude into the elevator hoisting space and interfere with the elevator hoisting. Also, to avoid that danger,
Considering the distance L between the fall prevention piece 22 and the dog 24 in the stowed state, if the distance between the pallet end in the stowed state and the elevator platform end in the stowed state is increased, the entire width of the parking device is increased and a large site is occupied. It was necessary, and there was a problem that it was difficult to install in a small city.

This invention solves such a problem in a fall prevention device of a parking device, and is a fall prevention piece in a stored state.
The distance L between the dog 22 and the dog 24 is reduced to prevent accidents due to the pallet 11 protruding into the elevator space.
It is an object of the present invention to provide a fall prevention device for a parking device, which can downsize the parking device.

[Means for solving the problem]

This invention, in a parking device including a parking room for storing a pallet loaded with automobiles, and an elevator for transferring the pallet from the loading / unloading floor to the parking room, a bracket fixed to a receiving room of the parking room, A fall prevention piece and a fall prevention release piece that are fixed to a shaft pivotally attached to this bracket and rotate at the same time, a dog that projects laterally from the pallet so as to abut against the lower prevention piece, and the front of the fall prevention piece (elevator). Fall prevention piece of the fall prevention device provided with a stopper for preventing rotation in the direction) and a fall prevention release cylinder for pushing the fall prevention release piece backward to rotate the fall prevention piece and allow the dog to pass forward. The above problem is solved by using a fan-shaped piece with a rear surface having an arc shape.

[Operation] In the fall prevention device, when the dog collides with the fall prevention piece when the pallet is stored, the fall prevention piece rotates rearward to pass the dog. After storing the pallet, when the pallet moves forward and the dog collides with the fall prevention piece, the stopper prevents the fall prevention piece from rotating forward, so the pallet is prevented from falling into the elevator space. To be done. Therefore,
Since the fall prevention piece is a fan-shaped piece having an arcuate rear surface, the distance between the fall prevention piece and the dog in the retracted state is small, and an accident due to the pallet protruding into the ascending / descending space of the elevator does not occur.

〔Example〕

 An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a front view of a parking device according to an embodiment of the present invention, FIG. 2 is a front view of a fall prevention device, FIG. 3 is a side view of the fall prevention device, and FIG. 4 is an operation of the fall prevention device. FIG.

As shown in FIG. 1, the parking apparatus 1 includes a multi-layered parking room 13 for storing a pallet 11 on which an automobile 2 is loaded, and an elevator 3 for transporting the pallet 11 to the parking rooms 13 of the respective layers. Receiving boxes 16 that support the wheels 15 of the pallet 11 are provided on both sides of the parking room 13. The elevator 3 is composed of a lift 12 for mounting a pallet 11 and moving up and down in the lift space 5, and an elevator drive device (not shown).
