Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single-column two-stage parking device that can efficiently use a parking space, and more particularly to a horizontally movable triangular support device and a horizontally movable pallet device. The present invention relates to a single-column two-stage parking device in which is installed.

The present invention also relates to a vehicle maintenance lift device of a single pillar type.

BACKGROUND ART With the recent rapid increase in vehicles, it has become difficult to secure a parking space. In order to relieve such difficulty of parking, a parking building (parking tower) is generally used in the city center as a mechanical parking facility, and an underground parking lot of a high-rise building in the city center,
Two-tiered parking facilities are used in the apartment complex and ordinary houses.

By the way, as the above-mentioned two-tier parking facility, there is a simple two-tier system in which one pallet is usually used to construct the first and second floors, as disclosed in Japanese Utility Model Publication No. 4-21977. Since such a simple two-stage system has two or four columns and is configured to support one second-floor pallet, there are many inconveniences such as obstruction to the passage of vehicles,
When the vehicle is parked on the first floor and the vehicle is to be loaded or unloaded from the pallet on the second floor, the vehicle parked on the first floor must be loaded or unloaded.

On the other hand, the puzzle-type two-stage parking facility is usually configured with four columns and is configured to support 4 to 5 pallets on the second floor, and the pallet on the first floor is configured to move horizontally. Although it complements the drawbacks of the step system, it costs a lot to install the columns and horizontal reinforcements, and the number of vehicles parked is limited due to the structural limitations of the horizontal reinforcements, and there are many inconveniences in space utilization. Due to the structural features, vehicles can be parked on the left and right only in parallel, and vehicles cannot be parked in the front and back in parallel. There was a problem that I was in trouble.

On the other hand, when using the single-column two-stage parking system, the vehicle must be parked at an appropriate position on the pallet if the driver's side door is opened so as not to interfere with the pillar. However, since the conventional pallet has a flat shape with only the protrusions for preventing wheel slippage at both ends, the driver stops while relying on the distance from the prop to visually check the outside of the vehicle window. There was a problem that I had to do it.

On the other hand, since a vehicle maintenance lift device used in a vehicle maintenance office usually has two columns, there is a problem in that the space is efficiently utilized.
