Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door opening preventing device and method for a mechanical parking device for storing a vehicle.

[0002]

2. Description of the Related Art Generally, in a mechanical parking apparatus, a pallet on which an automobile is placed (hereinafter simply referred to as "pallet")
The car door stored in the car is equipped with a car door opening prevention device that prevents the car and parking equipment from being opened while the machine is running, popping out from the pallet, and contacting other machine parts. .

As a conventional vehicle door opening preventing device, for example, Japanese Utility Model Publication No. 62-29551 is proposed. The side view is shown in FIG. The car door opening prevention device shown in the figure
A fixed fence (not shown) is provided on one side of the pallet 1 on which the vehicle is placed on the upper surface, and a movable fence 2 is provided on the other side of the pallet 1 to regulate the opening of the vehicle door on the side in the traveling direction of the vehicle. It is supposed to do. The pressing means 26 is fixedly provided on the platform 25 on the side facing the movable fence 2, and the movable fence 2 is opened and closed only when the designated pallet 1 is landed on the transfer surface. Specifically, when the pallet 1 is landed, the tip end fitting 27 of the pressing means 26 advances in the direction of the arrow and pushes the push rod 29 against the spring 28 to move the push rod 29 leftward. This movement is transmitted to the force point portion of the raising / lowering lever 31 via the link member 30 and the force point portion is rotated clockwise with the fixing pin 59 fixed to the pallet 1 as a fulcrum, so that it is in the closed position A. The movable fence 2 falls to the open position B indicated by the chain double-dashed line.

[0004]

In the conventional mechanical parking apparatus, one pallet is prepared for one vehicle, and empty pallets are stored in the parking apparatus in the same manner as the pallet on which the vehicle is mounted. Therefore, as described above, the vehicle door opening prevention device is in a state in which the movable fence is opened and closed only when the occupant of the vehicle gets on and off, and is always standing up when the pallet is empty and when moving and storing. .

However, due to the recent overcrowding of automobiles in urban areas, large-scale parking facilities are desired, and empty pallets are the same as pallets on which automobiles are mounted, like conventional mechanical parking devices. If each pallet is stored in the parking device, it takes a long time to move the pallets, which causes a problem that the housing efficiency of the vehicle is rather lowered. Therefore, a large number of pallets are stacked near the entrance and exit of the automobile to improve the accommodation efficiency of the automobile.

However, in the conventional vehicle door opening prevention device, the pallet cannot be stacked because the vehicle door opening prevention device for the pallets cannot be maintained in a tilted state.

The present invention has been made to solve such a problem. That is, it is an object of the present invention to provide a vehicle door opening prevention device and method capable of preventing the vehicle doors from opening and stacking pallets on which the vehicles are placed.
