【Example】

 The present invention will be described below with reference to illustrated embodiments. FIG. 1 shows the overall construction of a two-stage parking apparatus which is an embodiment of the present invention. In this figure, a boarding / alighting platform 22 is fixed to the device main body 21 fixed on the ground in the substantially vertical center thereof, and an elevating / lowering platform 30 on which the automobile 10 can be mounted is supported so as to be able to move up and down. The lift table 30 is lifted and lowered by the screw action of the ball screw mechanism 50. The ball screw mechanism 50 is operated by rotation of the drive wheels 11 of the automobile 10 on the lift 30. The rotation of the drive wheels 11 of the automobile 10 is transmitted to the ball screw mechanism 50 via the power transmission mechanism 40.

A fixed stopper 31 is provided on the upper surface of the right end portion of the lifting platform 30. A movable stopper 32 is provided on the upper surface of the left end portion of the lift 30. The movable stopper 32 is rotatably supported by the pin 33, can be tilted along the arrow A, and is tilted when the vehicle 10 moves in and out of the lift 30.

The power transmission mechanism 40 has friction rollers 41, 42 on which the drive wheels 11 of the automobile 10 are mounted. The friction rollers 41 and 42 are provided with a predetermined space as shown in FIG. As shown in FIG. 1, the drive wheels 11 of the automobile 10 are mounted on the friction rollers 41, 42 at a position slightly lower than the upper surface of the rollers so as to slightly fall between the rollers. It Interlocking pulleys 43 and 44 are fixed to the rotating shafts of the friction rollers 41 and 42, respectively. An endless belt 45 is wound around the interlocking pulleys 43 and 44, and the interlocking pulleys 43 and 44 are interlocked by the endless belt 45. A driving pulley 46 is fixed to the rotation shaft of the friction roller 41 along with the interlocking pulley 43. An endless belt 47 is wound around the drive pulley 46 so as to extend between the drive pulley 46 and the driven pulley 53 of the ball screw mechanism 50.

The screw shaft 56 of the ball screw mechanism 50 is provided in the apparatus main body 21 in the up-down direction, and the case 51 is moved up and down along the screw shaft 56, so that the elevating table 30 to which the case 51 is fixed moves up and down. To be done. The case 51 is moved up and down by the screw action of the screw shaft 56 and the short screw member 54. The short screw member 54 is connected to the power transmission mechanism 40 via the long screw member 52.

The long screw member 52 is rotatably supported in the case 51, and is screwed in a state of directly intersecting with the short screw member 54. One end of the long screw member 52 projects to the outside of the case 51, and a driven pulley 53 is fixed to one end of the long screw member 52.

The short screw member 54 is rotatably supported in the case 51 in a horizontal direction, and rotates in association with the rotation of the long screw member 52. A screw hole 55 is formed in the center of the short screw member 54, and a screw shaft 56 is fitted and inserted into the screw hole 55.

The operation of this embodiment will be described. When the two vehicles 10 are sequentially stored in the two-stage parking device, the first vehicle 10 is allowed to travel on the lift 30 with the movable stopper 32 tilted in the direction of arrow A. Then, the vehicle 10 is stopped at the position where the drive wheels 11 of the vehicle 10 are placed on the friction rollers 41 and 42, and the movable stopper 32 is set up in the original position.

In this state, the drive wheels 11 of the automobile 10 on the lift 30 are rotated to drive the friction rollers 41 and 42. The rotations of the friction rollers 41 and 42 are transmitted to the long screw member 52 via the endless belt 47. When the long screw member 52 rotates, the short screw member 54 screwed into the long screw member 52 rotates, and the elevating table 30 moves upward along the screw shaft 56 by the screw action. At this time, the ascending speed of the lift 30 can be easily adjusted by changing the rotation speed of the drive wheels 11 of the vehicle 10.

When the lift 30 approaches the upper limit position, the drive wheels 11 of the automobile 10 are stopped from rotating and the lift 30 is stopped. At this time, the driver descends from the automobile 10 onto the boarding / alighting platform 22 and then descends to the ground by stairs not shown. Then, another vehicle 10 is made to enter below the lift 30.

When the two automobiles 10 are sequentially unloaded from the two-stage parking device, the automobile 10 parked below the lift 30 is withdrawn from the parking device.

Next, the drive wheels 11 of the automobile 10 on the lift table 30 are rotated in the opposite direction to the direction of warehousing to drive the friction rollers 41, 42. The rotations of the friction rollers 41, 42 are transmitted to the long screw member 52 via the endless belt 47. When the long screw member 52 rotates, the short screw member 54 screwed into the long screw member 52 rotates and moves downward along the screw shaft 56 by the screw action. The case 51 is also moved downward with the movement of the short screw member 54, so that the lifting platform 30 is lowered. At this time, the descending speed of the lift 30 can be easily adjusted by changing the rotational speed of the drive wheels 11 of the automobile 10.

When the lift table 30 approaches the lower limit position, the drive wheels 11 of the automobile 10 are stopped from rotating and the lift table 30 is stopped. Then, the automobile 10 on the lift 30 is removed from the parking device.

As described above, according to the above-described embodiment, since the rotation of the drive wheels 11 of the vehicle 10 on the lift 30 is used as a drive source for moving the lift 30 up and down, a special motor such as a hydraulic motor is used. A multi-story parking facility can be easily configured without requiring any facility. This makes it possible to reduce the size and cost of the entire device.
