Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a home position device for a multi-story parking system in the form of a multi-story warehouse, which is a combination of a storage rack and an elevator.

Prior Art In cities, securing parking lots is extremely difficult both in terms of price and area, and the need for effective land use is increasing.As a countermeasure, various types of multi-level parking systems have been developed. It has been put into practical use.

Multilevel parking systems include self-propelled, gondola, and elevator types. Among them, elevator types are compact and can accommodate a large number of cars, and elevators only accommodate one car at a time. Since all you have to do is transport it, even if it is a large-scale item, the machinery and equipment will not be exaggerated, and the required loading/unloading time is short, which is a great advantage. In addition, if the elevator is equipped with a deck with comb teeth, and the storage shelf of the storage rack for storing cars is also formed with comb teeth that mesh with the comb teeth on the elevator side, the space between the comb teeth on one side can be connected to the other side. Because the comb teeth pass upward and downward, the transfer of motor vehicles between the elevator and the storage rack can be carried out extremely easily.

Problems to be solved by the invention However, when using such conventional technology,
A home position is formed on the ground floor of the storage rack, and when entering or leaving the storage rack, the car enters the elevator and is loaded onto the elevator, or exits from the elevator and is carried out at this home position. At this time, there was a problem in that the floor surface of the elevator had a rough comb-like shape, making it difficult for cars to enter and exit the elevator. This is because the comb teeth on the elevator side must be able to mesh with the comb teeth on the storage rack side, so it is impossible to narrow the interval beyond a certain level.

Purpose of the invention Therefore, in view of the actual state of the prior art, the purpose of this invention is to provide an auxiliary member with comb teeth at the home position that meshes with the comb teeth on the elevator side. To provide a home position device for a multi-level parking device which allows entry and exit of vehicles extremely easily.

Means for Solving the Problems The structure of this invention to achieve the above object is that a plurality of car storage spaces are arranged in a multi-layered storage rack, and a deck with comb teeth is mounted for use in transporting cars. and an auxiliary member with comb teeth provided at the home position of the storage rack, at least the comb teeth on the elevator side are recessed on the top surface leaving both ends, and are recessed for supporting automobile tires. The comb teeth on the elevator side and the comb teeth on the home position side are arranged at the same pitch with a half pitch difference from each other, and can be alternately meshed at the same level when the elevator is moved to the home position. That is the gist of it.

Effect When using this configuration, move the elevator to the home position, and at the home position,
When a car enters or exits an elevator, the comb teeth on the elevator side and the comb teeth on the home position side can be alternately meshed at the same level. With both comb teeth, it is possible to form a path for automobile travel in which the spacing between the comb teeth is sufficiently narrow. Therefore, it does not become difficult for cars to enter and exit. Note that the passage formed at this time has a recess formed in at least the comb teeth on the elevator side, so it becomes a passage with a guide groove, and there is a risk that the tire may come off the wheel inadvertently. do not have.
