Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a three-dimensional parking or luggage storage device that parks a large number of cars in multiple stages within a limited site or stores a large number of luggage. The present invention relates to a device for ensuring that pallets are accommodated in storage racks.

BACKGROUND ART In recent years, with the increase in the number of automobiles, it is necessary to secure parking lots in areas with especially high traffic volume, such as urban areas, and for this reason, multi-level parking systems that can accommodate a large number of automobiles in a limited installation space have been developed. It is widespread.

An example of the above-mentioned multilevel parking system is shown in FIG. 17 and will be described below.

In the drawings, 1 is a driving sprocket, 2 is a driven sprocket disposed vertically below the driving sprocket 1, 3 is a chain stretched between the driving sprocket 1 and the driven sprocket 2, 4, 4... 1 shows cages arranged at predetermined pitches on 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, .
It is constructed so that it always maintains a horizontal state regardless of its position. Incidentally, the entrance/exit of the automobile is formed at substantially the same position as the lowest position of the cage 4 (position P in FIG. 17).

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.

As mentioned above, the above-mentioned conventional multilevel parking system has a structure in which cages 4, 4, . It was hot.

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 chain 4 to the entrance/exit is complicated, and the drive source for the chain 3 also requires a high output power source. Furthermore, since the weight of all the cages 4, 4, etc. and the automobiles housed in the cages 4, 4, etc. are supported by the chain 3 and the drive sprocket 1 of the chain 3, the weight of the car is supported by the chain 3 and the drive sprocket 1 of the chain 3. This requires a new structure, making the device larger and more expensive.

Furthermore, regardless of the circulation direction of the chain 3, it is necessary to keep the cage 4 horizontal at all times, and the arrangement pitch of the cages 4, 4... and the drive sprocket 1 must be adjusted so that the cages 4, 4... do not interfere with each other. Since it is necessary to set the diameter, there are restrictions on improving the space utilization rate.

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.
