Description

[Detailed description of the invention] "Industrial application field" The present invention relates to a two-stage parking device for automobiles.

``Conventional technology'' Conventionally, when ascending, the rotational force of the vehicle's drive wheels was used, and when descending, the force of an electric motor installed on the support platform was used.

There was a two-tiered parking device (Utility Model Publication No. 38-13356), but it required electricity and equipment costs, and it was wide because the pinion was engaged with the rack and raised and lowered, and the support platform was moved horizontally. It required space.

"Problems to be Solved by the Invention" The present invention aims to provide a safe two-level parking device that does not require electric power or motive power, is a simple facility, and does not require space.

``Means for Solving the Problems'' The present invention includes a car support stand that is vertically movable up and down on a machine frame provided on the floor using a wire rope, and parallel rollers for supporting the drive wheels of the car are installed on the top surface of the support stand. the rotating shaft of one parallel roller and the wire rope winding drum device for raising and lowering the support platform are connected via a worm and a worm gear, and the other parallel roller is supported freely; The roller is provided with a floor surface proximity tightening band brake, and the two-stage parking device is configured such that the tightening is tightened on one side and loosened on the other side.

``Operation'' Accordingly, the vehicle support is lowered so that it touches the floor surface, and the vehicle is moved onto the support, and the driving wheels are placed on the parallel rollers for supporting the driving wheels. When the drive wheel is rotated in the direction of arrow C in Fig. 3, one of the parallel rollers rotates in the direction of arrow a (the loosening direction of the band brake), and the wire rope winding device is rotated via the worm and worm gear. ,
The wire rope is wound around the winding drum, and the support stand is raised to the center of the machine frame. When the rotation of the drive wheel is stopped, the wire rope winding drum device stops at that position without being reversed by the action of the worm and worm gear. drive wheel 3rd
When rotating in the direction opposite to arrow C in the figure, one parallel roller rotates in the direction indicated by the arrow, and the band brake is not applied.)
The wire rope winding drum device is rotated in the opposite direction via the worm and the worm gear, so that the wire rope is wound back onto the winding drum and the support base is lowered to the floor. Then, the band brake's floor surface proximity tightening device operates and tightens the brake, so one of the parallel rollers no longer rotates, so the drive wheel is rotated in the direction of arrow C in Figure 3 and the car is removed from the support platform. You can.

``Embodiment'' A machine frame 2 is provided on a floor surface 1, and a car support stand 3 is vertically mounted on the machine frame 2 so as to be able to be raised and lowered by a wire rope 4 for raising and lowering. Parallel rollers 7.8 for supporting the driving wheels 6 of the automobile 5 are provided on the upper surface of the support stand 3, and the rotating shaft 9 of one of the parallel rollers 7 and the winding drum device 10 for the wire rope 4 of the support stand 3 are provided.
are connected via a worm and a worm gear to the lifting device 1.
form 1. The other parallel roller 8 is freely supported by the support base 3. One of the parallel rollers 7 is provided with a band brake 13 having a floor surface proximity tightening device 12, so that the above-mentioned tightening is performed in the direction of the arrow C in FIG. 3 and loosened in the direction of the arrow. As shown in FIG.
The band 13a is tightened to the roller 7 with a force of 1, and as shown in FIG. It becomes easy to loosen. In the figure, 15 indicates a spring buffer stopper for the support base 3, 16 indicates a worm and a worm gear box, 17 indicates an undulating stopper, 18 indicates a cam for operating the undulating stopper/par, 19 indicates an operating spring, and 20 indicates a wire rope. 4 guide pulley.

゛ ``Effects'' Since the present invention is constructed as described above, the support stand 3 can be raised and lowered in an extremely simple and safe manner by simply rotating the driving wheels of the automobile mounted on the support stand 3 back and forth, without requiring any additional power. Therefore, a simple two-stage parking device can be obtained.
