Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parking system in which a pallet on which an automobile is mounted is moved up and down from the ground to a height of two steps so that another vehicle can be placed in an empty space provided below the pallet. .

[0002]

2. Description of the Related Art Conventionally, a two-stage structure has been used in which an automobile is mounted on a pallet that is moved up and down by power, and an empty space is created on the ground by ascending to a two-stage height, and another vehicle is placed in this space. Parking equipment has been developed and implemented.

5 to 9 are all conventional parking devices.

In the parking device shown in FIGS. 5 (a) and 5 (b), columns 30 are provided in four directions, and a pallet 32 is horizontally provided between beams having upper ends connected to two columns 30 on both sides by girders 31. ,
The pallet 32 should be guided along each pillar 30,
The pallet 32 is moved up and down via a pulling wire by an electric motor 33 fixedly mounted on the girder material 31 on one side.

This parking device has four columns 30, 30 ...
The pallet 32 has a stable structure because it is composed of
Although it can be evenly supported by four points, the installation space for the columns 30, 30 ... on all sides is taken, and these columns 30, 30 ... are an obstacle when entering the garage, making it difficult to enter and leave the occupant. There was a drawback that it was difficult to get on and off when getting on and off.

The parking device shown in FIGS. 6 (a) and 6 (b) is shown in FIG.
Remove the two columns on one side of the parking device in
It is supported only by 0 and 30, and a rising frame 34 is fixedly installed on one side of the pallet 32.
The pallet 32 is supported by a cantilever structure by being guided by 0.

When the automobile 36 is mounted on the pallet 32, a concentrated load acts on the fulcrum 32a of the pallet 32 with respect to the rising frame 34, and the pallet 32 itself is liable to bend. Further, if the short side of the pallet 32 is provided in the projecting direction as shown in order to prevent the pallet 32 from being bent, a vehicle mounted on the pallet 32 cannot open and close the front and rear doors on one side. .

The parking device shown in FIG. 7 has a rod-like structure in which two columns 30, 30 are provided on one side and a supporting arm 30a is provided on the column 30 for reinforcement, but unlike the parking device of FIG. The long side of 32 is the extending direction of the cantilever structure so that the automobile 36 can be mounted in the longitudinal direction with respect to the direction of the column 30.

Therefore, as the bulging of the pallet 32 becomes longer, the fulcrum 32a of the pallet 32 is subjected to a larger concentrated load than in the case of FIG. 6, and the pallet 32 is easily bent. In order to prevent this bending, it is necessary to reinforce with the brace 37, but since the pallet 32 needs to come into contact with the ground when descending, this brace 37 is used for the pallet 3.
In consideration of the opening and closing of the door of the automobile 36 mounted on the pallet 32, the mounting position of the brace 37 is also limited, and sufficient reinforcement cannot be expected.

The parking device shown in FIG. 8 has a base material 3 as a base.

9 is joined by a pin 39b at approximately the middle, and the support members 39, 3
A pallet 32 is provided on the upper end of the support member 9, and each support member 39 has pins 39a, 39a on one side of the support member 39 and the base member 38 and the pallet 32.
And the rollers 40 are respectively provided at the other ends of the base material 38
And the pallet 32 is moved up and down by the hydraulic cylinder 41 so that the X-shaped support members 39, 39 are expanded and contracted so as to be folded in the vertical direction.

However, in such a parking device, the X-shaped support members 39, 39 hinder the opening and closing of the doors on both sides of the automobile 36 that has been stored on the ground, so it is impossible to store the vehicle forward. Yes, and those in the rear seats are not allowed to get on and off in the garage. In order to make them possible, it is necessary to widen the space between both sides of the X-shaped support members 39, 39, which requires a large installation space for the entire parking device.

The parking device shown in FIG. 9 is provided with X-shaped support members 39, 39 on one side, like the parking device of FIG. 8, but pins 39a, 39 at the ends of these support members 39, 39 are provided.
The column 30 is provided at the joining position of a to secure the strength of the entire rod.

Also in this parking device, it is not possible to store the vehicle forward, and it is not possible for a person in the rear seat to get on and off while the vehicle is in the stored state. To make these possible, the X-shaped support members 39, 39 are required. It is necessary to widen the space on both sides of
Since a large installation space is required for the entire parking device, it has the same problem as in FIG.
