The two-stage parking device is provided with a vertically movable parking pallet so that two vehicles can be parked in one parking space. A conventional two-stage parking device will be described with reference to FIG. FIG. 5 shows a side surface of a conventional two-stage parking device.

As shown in the figure, a pair of guide rails 1 are erected at both sides of the vehicle 2 in a parking space of the vehicle 2 at the front and rear positions of the vehicle. A parking pallet 3 to be parked is supported so that it can be raised and lowered. An elevating drive device 4 is provided above the guide rail 1, and the elevating drive device 4 is provided with a drive sprocket 5 corresponding to each guide rail 1. The drive sprocket 5 has a drive shaft 6 extending from the lifting drive device 4.

[0005]

In the conventional two-stage parking apparatus, the lifting drive unit 4 is installed on the upper portion of the guide rail 1,
Since each driving sprocket 5 is simultaneously rotated to raise and lower the parking pallet 3 along the four guide rails 1, the portion for guiding the raising and lowering of the parking pallet 3 and the chain 7 are integrated, and the raising and lowering mechanism is provided. However, the installation period was long and the cost was high. Further, since the lifting drive device 4 is located above the guide rail 1, the workability of maintenance and inspection is poor. In addition, since there are four guide rails 1 for guiding the lifting and lowering of the parking pallet 3, the position of the guide rail 1 faces the passage for passengers, which poses a safety problem.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a two-stage parking apparatus intended to facilitate maintenance and inspection and shorten the installation period.

[0007]

In order to achieve the above object, the structure of the present invention is a parking pallet in which a pair of guide rails are erected at both side positions of the vehicle in a parking space of the vehicle so as to park the vehicle. The parking pallet is equipped with a drive motor that can be lifted up and down via a guide member and the output part is driven to rotate forward and backward.The drive sprocket is attached to the output part of the drive motor, while one end is on the upper end of the guide rail. It is characterized in that it is provided with a drive chain which is fixed and wound around a drive sprocket and the other end of which is fixed to a lower end of a guide rail and which raises and lowers a parking pallet by rotation of the drive sprocket.

[0008]

The tilting is guided by the guide member and the parking pallet is moved up and down along the guide rail. A drive motor provided on the parking pallet drives the drive sprocket of the output unit to rotate in the forward and reverse directions, and the parking pallet is lifted up and down without inclination through the drive chains fixed to the upper and lower ends of the guide rail.

As shown in the drawing, a pair of guide rails 22 are erected at positions on both sides of the vehicle 21 in the parking space of the vehicle 21, and the guide rail 22 is provided with a rail portion 23 having a U-shaped cross section. . Vehicle 2 on the guide rail 22
A parking pallet 24 on which 1 is parked is supported so as to be able to move up and down. That is, a pair of upper and lower guide rollers 25 as guide members are rotatably provided on the side portions of the parking pallet 24, and the pair of guide rollers 25 are rotatably fitted on the rail portion 23 of the guide rail 22. . That is, the pair of guide rollers 25 roll on the rail portion 23 of the guide rail 22, so that the parking pallet 24 moves up and down along the guide rail 22 in a state where the inclination is guided, that is, in a state where the inclination is prevented. It is like this.

A drive motor 26 is provided on the rear end side (right side in the figure) of the parking pallet 24, and the drive motor 26 has a drive shaft 27 as an output section. The drive shaft 27 extends in the width direction of the parking pallet 24 (vertical direction in FIG. 2), and the drive motor 26 drives the drive shaft 27 to rotate forward and backward. A drive sprocket 28 is attached to both ends of the drive shaft 27, and a driven sprocket 29 and two guide sprockets 30 are rotatably attached to the parking pallet 24 in correspondence with the drive sprocket 28. One end of the drive chain 31 is fixed to the upper end of each guide rail 22, and the other end of the drive chain 31 is fixed to the lower end of each guide rail 22. Each drive chain 31 has two guide sprockets 3 between one end side and the other end side.
It is wound around the drive sprocket 28 in a state in which tension is applied via 0 and the driven sprocket 29.
