Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a puzzle-type plane parking apparatus which can reasonably park as many vehicles as possible on a flat floor.

[0002]

2. Description of the Related Art A typical system for parking on a flat floor is, for example, a system in which a vehicle is self-propelled in each parking space provided on a flat floor in advance, or a pallet forming a parking space for the vehicle. There is a horizontal circulation system in which a car is parked on each pallet by cascading them in a loop along a flat floor and circulatingly moving this on a fixed track.

Further, as seen in JP-A-61-292514 and JP-A-63-267471, a plurality of pallet trucks for mounting vehicles are provided so that each pallet truck can move independently. A puzzle-type parking device has been proposed in which the vehicle is parked on an arbitrary pallet truck by moving the vehicle in a puzzle manner.

[0004]

The above-mentioned self-propelled parking system of the vehicle requires a passage for the traveling of the vehicle, and the horizontal circulation system has to form a pallet loop. Since the arrangement of the floors is limited, the flat floor cannot be used reasonably by either method.

Further, although the above-mentioned puzzle-type parking device promotes effective use of the flat floor as compared with the above-described self-propelled parking system and the horizontal circulation system, the rail for supporting the pallet truck and the This makes the structure of the related vehicle such as the direction changing mechanism complicated, which is expensive.

In view of the above problems, it is an object of the present invention to provide a novel puzzle-type flat parking apparatus which enables a rational use of a flat floor with a simple and inexpensive structure.

[0007]

In order to achieve the above object, in the present invention, the center line of each row and each column on a flat floor provided with parking lots arranged in a plurality of rows and a plurality of columns is vertically or horizontally or curvedly formed. One support rail with a built-in power line was laid, and a cross-shaped rotary rail that was rotatable was provided at the intersection.
In addition, guide rails are laid in the periphery of the parking space, and a plurality of pallet trucks, which are one less than the number of parking areas, are arranged through these three rails, and each truck is supported by a support rail or a cross-shaped rotating rail. And a cross-shaped rotary rail having wheels that can be rotated by receiving electric power supplied from an electric power line and a traveling motor that rotates and rotates the wheels. A mechanism for turning the pallet is provided so that each pallet truck is moved in a puzzle manner.

[0008]

The pallet truck is moved by the rotation operation of the traveling motor, and when it is moved, it is guided by the support rail or the cross-shaped rotary rail, and is also stably guided by the guide rail via the caster. Further, the mechanism for turning the wheels enables the pallet truck to travel vertically and horizontally. However, the support rails which are not only vertical and horizontal but also curved give the parking lot an arbitrary arrangement, and the fact that there is only one support rail for supporting the pallet truck simplifies the installation. As a result, the number of crossing support rails is reduced, and the number of mechanisms for turning the wheels of the pallet truck is reduced, which contributes to simplification of the structure.
