DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-story parking apparatus in which a pallet on which a vehicle is mounted is lifted from the ground to a height of a second floor so that another vehicle can be loaded into an empty space below the pallet. .

[0002]

2. Description of the Related Art Conventionally, a vehicle is mounted on a pallet that is moved up and down by power, and an empty space is created on the ground by climbing to the height of the second floor, and another car can be loaded here. The device is being developed.

9 to 13 are all conventional parking devices.

In the parking device shown in FIGS. 9 (a) and 9 (b), columns 30 are provided in four directions, and a pallet 32 is horizontally provided between beams whose upper ends are connected to each other by two columns on both sides of the columns 30. The pallet 32 is provided so as to be guided along each of the support columns 30, and 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 ...
Therefore, the pallet 32 can be evenly supported by each of the four columns. However, the installation space for the four columns 30, 30 ... Is taken, and these columns 30, 30 ...
However, it was difficult to get in and out of the car, and it was difficult for passengers to get in and out of the car.

The parking device shown in FIGS. 10 (a) and 10 (b) has two columns on one side of the parking device shown in FIG. 9 removed, and is supported only by the two columns 30, 30 and is erected on one side of the pallet 32. The raising frame 34 is fixed, and the raising frame 34 is attached to the two columns 30,
The pallet 32 is supported by a cantilever structure by being guided by 30.

However, when a vehicle is mounted on this parking device, the load is concentrated on the fulcrum 32a of the pallet 32, and the pallet 32 is bent. Further, as shown in the figure, if the short side of the pallet 32 is provided in the projecting direction, the vehicle riding on the pallet 32 cannot open and close the front and rear doors on one side.

The parking apparatus shown in FIG. 11 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 apparatus in FIG. The long side of 32 is the projecting direction of the cantilever structure so that the vehicle 36 can be mounted in the longitudinal direction with respect to the direction of the column 30.

Therefore, as the bulge 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. 10, and the pallet 32 is easily bent. A brace 37 is provided and reinforced in order to prevent this bending. However, since the pallet 32 needs to be brought into contact with the ground when descending, the brace 37 must be attached to the upper side of the pallet 32, and the pallet 32 must be attached. Considering the opening and closing of the door of the vehicle 36 mounted on the vehicle, the mounting position of the brace 37 is also limited, and sufficient reinforcement cannot be expected.

The parking device shown in FIG. 12 has two support members 39 each having an X shape on each side, on a base material 38 serving as a base.
39 is joined by a pin 39b at approximately the middle,
A pallet 32 is provided on the upper end of 39, and each support member 39 has pins 39a, 39
and the roller 40 is provided at each of the other ends of the base material 3
8 and the pallet 32 to move along,
The hydraulic cylinder 41 elevates and lowers the pallet 32 by expanding and contracting the X-shaped support members 39, 39 so as to be folded in the vertical direction.

However, in such a parking apparatus, the X-shaped support members 39, 39 hinder the opening and closing of the doors on both sides of the vehicle 36 that has entered the ground, so it is impossible to enter the vehicle forward. Yes, and when entering the vehicle in the backward direction, the person in the back seat cannot get on or off the vehicle in the entered state at all. To make them possible, X-shaped support members 39, 3
It is necessary to widen the space on both sides of 9, and a large installation space is required for the entire parking device.

The parking device shown in FIG. 13 is provided with X-shaped supporting members 39, 39 on each side similarly to the parking device shown in FIG. 12, but pins 39a at the end portions of these supporting members 39, 39 are provided.
The support column 30 is provided at the joining position of 39a to secure the strength of the entire rod.

This parking device also has the same drawbacks as the parking device shown in FIG. 12 in that it cannot be stored in the forward direction and that if the vehicle is stored in the backward direction, a person in the rear seat cannot get on and off in the stored state. Therefore, 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 causes a problem that a large installation space is required for the entire parking device.

[0014]

Rolling wheels are provided on both upper and lower sides of a stand-up frame fixed to the column side, and driving means for guiding the rolling wheels of the stand-up frame to the guide grooves of the column on both sides to raise and lower the pallet are provided. , A roller provided on the other end of a support arm rotatably joined to each lower end of the support column is engaged with a track guide of roller guides provided on both sides of a substantially center of gravity of the pallet to further support the both sides. The middle of the arm and both upper ends of the rising frame of the pallet are pin-joined to each other by the pulling arm.

Further, the output shaft of a drive motor fixedly mounted on the upper end of the rising frame of the pallet is connected to a connecting shaft extending in both horizontal directions of the starting frame, and both ends of the connecting shaft are fixed to the pallet. And a pinion fixed to both ends of the connecting shaft meshes with a rack fixed in the vertical direction along the guide groove of the column, and a roller provided at the upper end of the stand-up frame includes the pinion and the roller. The rack has an outer diameter that keeps the meshing distance constant and rolls along the guide groove of the column.

[0017]

In the above-described structure of the present invention, the pallet is in a cantilever state in which it is extended to one side of the support column because the four rolling wheels of the rising frame of the pallet are guided by the guide grooves of the support column. When this pallet is lowered to the ground, the vehicle can be moved forward or backward in the vertical direction toward the stanchions and stored in the pallet, and by raising the pallet, an empty space is created on the ground below the pallet and another vehicle can be loaded. You can get in.

The pallet is supported on the supporting column side by means of four rolling wheels of the stand-up frame, and is supported from below on both sides of the gravitational center position of the pallet by supporting arms having pin fulcrums at the lower end position of the supporting column. Also, since the middle of the support arms on both sides and the upper ends of both sides of the pallet raising frame are pin-joined to each other by the pulling arm, when the pallet is lifted by the driving means, the pulling arm pulls the supporting arm upward. hand,
The support arm is rotated around the pin fulcrum at the lower end. At this time, the roller provided at the tip of the support arm rolls along the trajectory guide of the roller guide provided at the side of the pallet and draws a constant trajectory while varying the engaging position of the roller as the pallet rises. By doing so, the pallet is always supported on both sides of the position of the center of gravity.

In the above structure, the support arms that support both sides of the pallet occupy only the upper corners of the columns of the first stage space when viewed from the side of the pallet, so that the vehicle is advanced below the pallet. Or, even if you enter the car in reverse, it does not obstruct the opening and closing of the front and rear doors of this vehicle, and there is no parking device on the side of the door opening / closing position, so passengers can get in and out of the car completely. You can do it.
