Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a multi-story parking lot for parking a large number of vehicles.

[Prior art]

In many conventional multi-level parking garages, the lift itself is used as a parking space, and the lift circulates to bring cars in and out, or the lift moves cars in and out of each floor, and the cars drive themselves within the floor. I am using something that is designed to be used for parking. If the lift itself is used as a parking space, the equipment cost of the parking lot will increase, and parking efficiency will decrease because space must be provided for the lifting mechanism of the lift. On the other hand, if vehicles are allowed to run on their own on each floor, space for vehicle movement is wasted. Furthermore, the position of the ceiling of each floor must be determined according to the height of a person, which is wasteful compared to the vehicle height. Furthermore, when a vehicle is driven by itself, space is required to open and close the door, resulting in waste. Furthermore, moving the lift and moving the vehicle are performed separately, so it takes time to move the vehicle in and out.

On the other hand, Japanese Patent Publication No. 45-4011 proposes a mechanical multi-level parking lot. In this multi-story parking lot, vehicles loaded on pallets are moved to the parking floor together with the pallets to enter the parking lot, and vehicles are moved together with the pallets from the parking floor to a lift to exit the garage. Inside the parking floor, pallets are circulated and parked. However, this multi-story parking lot has a problem in that it requires movement of transporting and returning empty pallets when vehicles enter and exit the garage, and it takes time to enter and exit the garage.

For example, when a vehicle is put into a warehouse, the vehicle is sent out to the parking floor together with a pallet, so it is necessary to load and transport empty pallets onto a lift before the next time the vehicle is put into the warehouse. That is, when a vehicle is loaded onto a pallet from the lift and moved to the parking floor, the lift runs out of pallets, so the empty pallet must be loaded and transported onto the lift before loading the next vehicle.

Similarly, in the case of unloading, empty pallets remain on the lift each time a vehicle is unloaded. Therefore, the empty pallets remaining on the lift must be returned to the parking floor before the next vehicle is transported.

As a result, each time a vehicle enters or exits the parking lot, it is necessary to transport empty pallets from the parking floor to the lift (in the case of warehousing) or return empty pallets to the parking floor (in the case of outbound parking). Exercise is required. This reduces the speed of vehicle entry and exit. In particular, when it is necessary to enter and exit the warehouse continuously, the waiting time for users is significantly extended, which is inefficient.

[Problem of invention]

An object of the present invention is to eliminate the need for unnecessary movement of empty pallets in a mechanical multi-story parking lot, thereby shortening the time required for loading and unloading.

[Structure of the invention]

The multi-story parking lot of the present invention is a multi-story parking structure in which vehicles are moved in and out of the parking floor using a lift, and the parking floor is provided with pallets, and a pallet moving means is provided for moving the pallets within the parking floor. The lift includes an elevator for entering vehicles into the parking floor, and
It is composed of two types of elevators: an exit elevator for taking vehicles out of the parking floor; the entering elevator is provided with a first sliding means for moving the loaded vehicle to the pallet in a side-slipping motion; The present invention is characterized in that a second sliding means is provided for moving the vehicle to the exiting elevator in a sideways sliding motion.

In this invention, the vehicle is moved from the warehousing elevator to the pallet on the parking floor by skidding by the first sliding means, and then moved from the pallet to the exiting elevator by the second sliding means.
To move a vehicle by sliding it sideways using a sliding means. That is, in this invention, instead of mounting the vehicle on a pallet and moving the vehicle between the elevator and the parking floor,
Only the vehicle is moved sideways by the first and second sliding means. In the following, examples will be described with the pallet being referred to as a parking pallet. In addition, when referring to the two types of elevators, one for warehousing and one for warehousing, the term ``lift'' is used, and when referring to individual elevators, the terms ``input elevator'' and ``exit elevator'' are used to describe the embodiments. do.

When exiting the vehicle, the driver searches for the parked pallet 12 using the vehicle key, etc., and operates the exit switch 84.
In the microcomputer, the position of the pallet 12 is detected by a signal source 76, and the chain belt 44 is operated to move the necessary pallet 12 to the front of the elevator 6. At the same time, the elevator 6 moves to the corresponding floor 10. Next, while confirming that the pallet 12 is in the correct position using the sensor 48, the jack 46 tilts the pallet 12, and the vehicle 02 is moved into the elevator 6. Vehicle 02
When the sensor 34 detects the movement of the elevator 6
The vehicle 02 descends, and the vehicle 02 runs on its own from the first floor and exits.

In the embodiment, the pallets 12 are arranged so as to circulate around the floor 10, but any pallet that moves within the floor 10 may be used. Further, this multi-level parking lot is particularly effective in a structure having a plurality of floors 10, but it may also be one in which the floor 10 is one layer. Also lift 2
By simultaneously raising and lowering the pallet 12 to the parking floor 10 and moving the pallet 12 to the front of the lift 2, the time required for entering and exiting the warehouse can be significantly shortened.

〔Effect of the invention〕
