Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a fork for supporting a car in a multi-story parking system that can stably support a car brought in.

Prior Art The applicant previously proposed, as a means of solving the problem of securing parking lots in cities, a storage rack configured by stacking car storage spaces in multiple stages, and a stacker crane that can run and move along the storage rack. We proposed a multi-storey parking system in the form of a multi-storey warehouse.

There, the car loading fork device and the car storage shelf are formed with comb teeth that mesh with each other and can pass up and down, and the car loading fork device extended in the car storage space is moved up and down, and one of the comb teeth is By supporting the contact surface of the car tire supported on the top surface on the top surface of the other comb teeth, it is possible to transfer the car between the car storage shelf and the car loading fork device without using a pallet. Transfer has been achieved. The comb teeth that support the vehicle in this way form vehicle supporting forks for both the vehicle loading fork device and the vehicle storage shelf, respectively.

Problems to be Solved by the Invention However, the multilevel parking system according to this prior art does not include any positive means for preventing the automobile tires supported on the upper surfaces of the comb teeth from sliding off the comb teeth. Therefore, it was not possible to completely prevent the tires from slipping off due to careless movement of the vehicle, and there was room for improvement from the viewpoint of safety.

Therefore, in view of the actual state of the prior art, the purpose of this invention is to provide a new fork for supporting a car in a multi-level parking system, which is improved so that the car carried in will not accidentally slip off the comb teeth. It's about doing.

Means for Solving the Problems The structure of this invention to achieve the above purpose is to provide a horizontally protruding comb tooth in accordance with the position of the car's tires, and to use it as a car support for a multi-story parking system that supports cars brought in. The gist of this fork is that it has a depression on the upper side of the comb teeth, and the depression forms a smooth recess into which an automobile tire can be dropped.

With this configuration, since a smooth recess is formed on the upper surface of the comb teeth, the weight of the vehicle on the tire always acts in the direction of dropping the tire into the deepest part of the recess. Therefore, there is no danger that the automobile supported on the comb teeth will accidentally slip off the comb teeth.

Example Embodiments will be described below with reference to the drawings.

The car supporting fork of the multi-story parking system has comb teeth 13a, 13a..., 23a, 2 that mesh with each other.

c, 23c... are formed (same figure). These depressions 13c, 13c..., 23c, 23c...
... are provided on the individual comb teeth 13a, 23a, and the position, size, and depth of the comb teeth 13a, 13a..., 2 are determined for each automobile support fork.
In addition to forming smooth recesses on the upper surfaces of 3a, 23a, etc., when the relative heights of the car storage shelf 13 and the car loading fork device 23 are matched, one smooth recess is formed as a whole. (Fig. 4). Further, the position is such that it can cover the range that supports the contact surface Cg of the tire Ct of the automobile C.

When loading the car C on the car loading fork device 23, the contact surface Cg of the tire Ct of the car C
However, the car C is positioned and stopped in a state where it falls into the recess above the comb teeth 23a, 23a (third
figure). At that time, the weight of the car C acting on the slope of the recess acts in the direction of dropping the tire Ct into the deepest part of the recess, so the car C
3a, 23a, . . . can be effectively eliminated.

Next, the car loading fork device 23 loaded with the car C is positioned slightly above the car storage shelf 13 and inserted and extended into the car storage space 11 (the top stage in FIG. 1). Comb teeth 13a, 13a..., 2
At the position where 3a, 23a... engage without interfering with each other, the automobile loading fork device 23
When lowered, the comb teeth 23a, 23a... pass between the comb teeth 13a, 13a... from top to bottom, so that the car C supported on the comb teeth 23a, 23a... The tire Ct has comb teeth 13a, 1
