Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional storage device capable of efficiently storing automobiles, luggage, and the like in a small space, and easily putting in and out.

[0002]

2. Description of the Related Art There are many known multi-story parking devices for efficiently parking an automobile. For example, JP-A-3-9657
As described in Japanese Patent Publication No. 6, a pallet for mounting a car is provided in a multi-row, multi-row, multi-stage manner, and the pallets in each stage except for the lowermost stage are used for raising and lowering the pallet. The lifting device is installed independently. In addition, since the lowermost stage is on the same plane as the doorway of the automobile, no lifting device is required. In addition, since the elevating device may be attached to the beam or the like of the multi-story parking device at the uppermost stage, the elevating device may not be attached to the pallet.

The lifting device independently mounted on each pallet is, for example, an L-shaped carriage (a) as shown in FIG. 6, and winds and winds a wire (c) by a winding drum (b). It is possible to return. A pallet (d) is connected to one end of the wire, and the pallet (d) can be lowered by rewinding the wire. Therefore, the vehicle placed on the pallet can be moved up and down by winding and rewinding the wire of the lifting device, thereby taking the vehicle in and out.

[0004] This multi-story parking device can park a large number of vehicles in a small space and can save space in the parking lot. However, since a lifting device must be attached to each pallet, the production cost is increased. Will be higher. In addition, due to its structure, the lifting device cannot raise the pallet to a position higher than the cart, and there is a problem that a parking space cannot be provided on the ground floor below the entrance of the vehicle.

[0005] Therefore, without providing an independent elevating device for each pallet on which a car is mounted, an elevating member capable of elevating from the uppermost stage to the lowermost stage of the multi-story parking device is used. It is convenient to raise or lower a car so that the car can enter and exit. Accordingly, the applicant has filed a patent application on May 31, 1995 regarding a "storage device for a stored product in a three-dimensional storage device".

[0006] This access device is a combination of a mounting member for mounting a storage item such as an automobile and an elevating member capable of moving up and down for gripping the storage item. In the apparatus, the mounting member is provided with a first comb-shaped fork, the elevating member is provided with a rotatable second comb-shaped fork that meshes with the first comb-shaped fork, and the second comb-shaped fork is configured such that the elevating member holds a stored item. When ascending and descending without gripping, the second comb-shaped fork rotates and meshes with the first comb-shaped fork when the second comb-shaped fork approaches the first comb-shaped fork. The two comb-shaped forks are fixed,
It is configured to be able to hold and hold the stored item and get in and out.

[0007] In the storage device of the above-mentioned three-dimensional storage device, a car can be placed on a mounting member and suspended by an elevating member. However, since all mounting members must be provided with a traveling drive device. The structure is complicated and the production costs are very high. A support frame provided with an elevating member is provided at the uppermost stage of the apparatus. When the supporting frame moves to a predetermined place, the elevating member is lowered to grip and suspend the automobile. Since the support frame is located at the uppermost stage, it takes time to descend the elevating member to suspend a vehicle on a predetermined floor, and it takes time to take the vehicle in and out.

[0008]

As described above, the conventional three-dimensional storage device has the above-mentioned problems. The problems to be solved by the present invention are these problems. To provide a three-dimensional storage device which has a simpler structure, is less expensive to manufacture, and does not require much time for taking in and out of a car or the like.
