Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-tiered parking system, and after moving forward and turning to the outside of the parking system with the vehicle mounted on the lower pallet, the upper tier is set in the empty lower tier. The present invention relates to a parking device in which a car is moved in and out of the upper pallet by lowering the pallet.

[0002]

2. Description of the Related Art Conventionally, a car is loaded into a pallet that is moved up and down by power, a vacant space is created on the ground by raising this pallet to a height of two steps, and another car is loaded into the pallet to form a vertical shape. A two-stage parking system for parking two cars has been developed.

However, in such a two-tiered parking system, when another vehicle is parked in the lower space, the upper pallet cannot be lowered unless the vehicle in the lower space is moved. It required a troublesome work of moving the car outside the parking device by driving and then lowering the upper pallet.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks of the conventional parking device.
It is an object of the present invention to provide a parking device that is provided with a lower pallet in addition to the upper pallet and allows a vehicle to be loaded and unloaded from the upper pallet while the vehicle is parked on the lower pallet.

[0005]

In order to solve the above-mentioned problems, a parking apparatus according to the present invention comprises an upper pallet which is moved up and down between pillars standing on all four sides of the ground and a lower pallet which moves on the ground. In the parking device provided with the above, a H-shaped guide rail is laid across the front and rear columns on one side, and a plurality of horizontal wheels and lower flanges that roll by sandwiching the web from both sides on the guide rail are provided. A traveling block provided with a plurality of vertical wheels placed on both inner surfaces and rolling is provided, and a rack fixed along the guide rail and a pinion provided on the traveling block are meshed with each other, and the traveling block is provided. A traveling motor is provided to connect the traveling motor to the pinion, and the lower pallet is supported on the ground by casters fixed to the four sides of the lower surface, and the lower pallet is A swing shaft is provided at the end of an arm fixed to the side rear end so as to be horizontally rotatable with respect to the traveling block, and a swing motor provided in the traveling block is coupled to the swing shaft of the arm. is there.

[0006] Further, guide rollers standing upright on the ground along both sides of the lower pallet may guide the straight traveling of the lower pallet.

[0007]

According to the above-described structure of the present invention, an H-shaped guide rail is laid over the front and rear pillars on one side of the four pillars erected on the ground, and is driven along the guide rails. A lower pallet is pivotally connected to a traveling block via an arm.

Further, casters are provided on four sides of the lower surface of the lower pallet so that the movement of the lower pallet can be supported horizontally with respect to the ground.

In such a traveling movement, a plurality of vertical wheels provided on the traveling block support the traveling block so as to be able to travel along the guide rails, and a plurality of horizontal wheels provided on the traveling block are traveling. It is designed to prevent lateral shake.

When the traveling motor is driven, the traveling block travels along the guide rail due to the meshing of the pinion connected to the traveling motor and the pinion fixed to the guide rail. When the traveling block travels along the guide rail, the lower pallet connected by the arm moves forward to open the lower space.

When the turning motor is driven after the lower pallet has moved straight out of the lower space, the lower pallet turns in a direction at a right angle to open the front of the lower space, so that the lower pallet is lowered to the lower space. It is possible to load and unload cars on the pallet.

Further, the guide rollers which are erected on the ground along both sides of the lower pallet ensure the straightness of the lower pallet during traveling.

Is configured to move up and down.

Further, although the above parking device is a two-stage parking device which is independent, it is also possible to arrange the two-stage parking devices of the present invention in a plurality of rows side by side, as shown in FIG. Is.

The usage of the parking apparatus of the present invention is shown in FIG. 1. In FIG. 1, the vehicle C travels with the lower pallet 3 accommodated in the lower space S1 (see FIGS. 10 and 11). When the driving motor 10 is driven, the traveling block 7 travels along the guide rails 4, and the lower pallet 3 is sandwiched between the guide rollers 16 on both sides, and keeps straightness, and moves forward in the lower space S1 as indicated by the arrow. Be driven.

As a result, when the traveling block 7 reaches the front end of the guide rail 4 and the turning shaft 14 of the arm 13 reaches the front of the front strut 1 (position of the vehicle C1), the driving motor 10 is stopped. . At this time, the lower space S
1 becomes an empty space, and the upper pallet 2 can be lowered.

Next, by driving the turning motor 15, the lower pallet 3 turns through the arm 13 at a right angle, and the driving of the turning motor 15 is stopped at the position where the front of the lower space S1 is open.

At this time, the front of the lower space S1 is opened. When a car is mounted on the upper pallet 2 that has descended on the ground, the car is driven to lower it to the outside. In addition, when parking a car on the empty upper pallet 2, the lower space S1
Keep the car waiting in front of and get on the upper pallet 2.

After the loading / unloading of the vehicle onto / from the upper pallet 2 is completed, the upper pallet 2 is raised to move to the lower space S.
1 is an empty space, the lower pallet 3 is rotated and returned in the order opposite to the above to position the lower pallet 3 between the guide rails 16 and 16, and the lower pallet 3 is moved backward by the traveling motor 10 to lower the lower space S1. House inside.

[0040]

As described above, according to the parking device of the present invention, it is possible to construct a parking device having a two-stage structure in which an upper pallet and a lower pallet are vertically arranged, and a vehicle is parked on the lower pallet. By moving the lower pallet straight out of the parking device and turning in this state, the lower tier and the front of the lower tier can be used as an empty space, and the upper pallet is lowered to the lower tier that has become the empty space. Then, the car can be loaded and unloaded on this upper pallet.

Therefore, in the conventional apparatus, when the car is parked below the upper pallet, the car had to be driven to move. According to the present invention, the car is placed on the lower pallet. It will be possible to move the vehicle while it is installed, and to freely load and unload vehicles on the upper pallet.

The parking device of the present invention is a two-tiered parking device having an independent structure, and a plurality of parking devices can be arranged in parallel by arranging the parking devices in a row.
