DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a multilevel parking system for parking a large number of cars within a limited lot.

BACKGROUND OF THE INVENTION In recent years, with the increase in the number of cars, multi-story parking systems that can accommodate a large number of cars in a limited installation space have become popular in order to secure parking spaces in urban areas and the like.

An example of the above-mentioned multilevel parking system is shown in FIG. 16 and will be described below.

In the drawing, 1 is a driving sprocket, 2 is a driven sprocket arranged vertically below the driving sprocket 1, 3 is a chain hung between the driving sprocket 1 and the driven sprocket 2, 4, 4... 1 shows cages arranged at predetermined pitches in the chain 3 and housing automobiles therein.

The drive sprocket 1 is driven by a drive device (not shown) by appropriately switching the direction of rotation in both forward and reverse directions, and circulates the chain 3 wrapped around the drive sprocket 1 between it and the driven sprocket 2.

The cages 4, 4, . . . are respectively movable relative to the chain 3, and are configured to always maintain a horizontal state regardless of the position of the chain 3 by appropriate means. Incidentally, the entrance/exit for the automobile is formed at approximately the same position as the lowest position of the cage 4 (position P in FIG. 16).

To move a car in and out of the multi-story parking system, rotate the drive sprocket 1 in an appropriate direction to move the cage 4 containing the desired car or the empty cage 4 to the lowest position, and hold it at this position. Vehicles will enter and exit through the provided entrance.

Problems to be Solved by the Invention As mentioned above, the conventional multilevel parking system has a structure in which cages 4, 4, etc. for accommodating cars are attached at predetermined pitches to an endless chain 3 that circulates in the vertical direction. As a result, the following problems arose.

In the above-mentioned multilevel parking system, in order to move the predetermined cage 4 to the lowest entrance/exit when loading and unloading a car, it is necessary to move all the cages 4, 4, etc. by the circulation drive of the chain 3. The control for moving the cage 4 to the entrance/exit is complicated, and the drive source for the chain 3 also requires a high-output one. Furthermore, all the above cages 4,
Since the weight of the automobile housed in the cages 4, 4, and the cages 4, 4, is supported by the chain 3 and the drive sprocket 1 of the chain 3,
A strong support structure is required, making the device large and expensive.

Furthermore, regardless of the circulation direction of the chain 3,
It is necessary to keep the cage 4 horizontal at all times, and it is also necessary to set the arrangement pitch of the cages 4, 4, and the diameter of the drive sprocket 1 so that the cages 4, 4, and so on do not interfere with each other. rate improvement is constrained.

Furthermore, it is extremely difficult to change the vehicle accommodation capacity of the above device in response to changes in location conditions due to its structural limitations.
