[Object of the Invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-stage parking system which enables a vehicle to be parked in multiple stages over the ground and underground.

[0002]

BACKGROUND OF THE INVENTION The popularity of automobiles in recent years has been remarkable, and it is becoming common for households to own two or more automobiles. However, securing a parking space for two cars in each home is not easy under the circumstances of the residential land in Japan, where the underground price is soaring. Therefore, recently, various ideas have been made to effectively utilize the limited parking space, and one of them is an underground multi-story parking garage.

This is one in which a parking space for another vehicle or a plurality of parking spaces is provided below the conventional ground parking space. And in this kind of device, the movement of the car between the above-ground parking space and the underground parking space is performed by the lifting device, and this lifting device basically puts a mounting table for mounting the car and this mounting table. It has a support member that supports at a plurality of locations, and a drive device that moves the mounting table up and down via the support member.

Of these, the mounting table is, for example, composed of a mounting plate on which the automobiles are mounted one above the other, and a supporting column provided between the two mounting plates for supporting the two mounting plates in parallel. However, if the vehicle is not parked in the proper position or if the brakes are not fully applied, the vehicle may move when you move it up or down, and the wheel may drop or the vehicle may drop from the mounting plate. There was a risk that it would end up.

Further, the supporting member is a pantograph type or a chain hanging type, and the drive unit has a mechanical transmission means using an electric motor as a drive source, and a hydraulic pump using a hydraulic pump as a drive source. There are various types such as those using cylinders, but safety measures in case of failure of some of them are not always perfect.For example, there is some failure in the support member supporting the mounting table. In that case, there was a risk that the support would be incomplete and the mounting table would tilt, or the supporting table would drop without any support.

Further, the mounting table is supported by a plurality of fulcrums in order to stabilize the posture of the vehicle during transportation. When transmitting power for raising and lowering the mounting table to these fulcrums, a plurality of bases are used. There is a case where the drive device is used. This is intended to increase the driving force for raising and lowering the mounting table, but on the other hand, it is extremely difficult to operate all the driving devices uniformly. Accuracy is required, leading to an increase in manufacturing cost. This also applies to commercial parking lots and larger underground multistory parking facilities.

[0007]

[Technical Items Attempted to Develop] The present invention has been made from such a background, and it is possible to improve the shielding property of a container on which a vehicle is mounted and to improve the safety in the event of failure of the lifting device. This is an attempt to develop a new multi-tiered parking system.

[0008]

[Constitution of the invention]

[Means for Achieving the Object] That is, the multistage parking apparatus according to the first invention of the present application forms an underground parking space below the above-ground parking space, and an elevator is provided in this underground parking space. In a parking device that enables multi-level parking on the ground and underground by transferring a vehicle between a parking space and an underground parking space, this parking device stores the vehicle in a closed container and underground parking. In addition to transporting and storing the vehicle to a space, when transporting the vehicle, one drive motor is used as a drive source and the output is distributed to move the container up and down. .

In addition to the above requirements, in the multistage parking apparatus according to the second invention of the present application, in addition to the above requirements, the elevating apparatus drives the drive motor and the rotation of the output shaft of the drive motor into a ball screw unit in the subsequent stage by chain drive. It comprises a chain transmission mechanism for transmitting and a ball screw unit for directly moving up and down the container by receiving the power transmitted by the chain transmission mechanism, and a worm gear is interposed between the chain transmission mechanism and the ball screw unit. It is characterized by doing.

Furthermore, in addition to the above requirements, in the multistage parking apparatus according to the third invention of the present application, one end of a suspending wire that is extended upward is connected to the container. The wire is characterized in that it is wound around a relay pulley located above and then hangs downward, and a balance weight is provided at the tip thereof. Then, by using these inventions, the object of the invention is achieved.

[0011]

First of all, according to the present invention, since the vehicle to be transferred is housed in a closed container, there is no danger that the vehicle will drop from the container during the transfer. Further, since one drive motor is used as a drive source and its output is distributed, it is not necessary to pay attention to synchronization of each motor, which is a problem when a plurality of motors are used.

Further, in the present invention, since the worm gear is interposed between the chain transmission mechanism and the ball screw unit,
Even if a failure occurs and the container may fall freely as it is, the ball screw unit is prevented from freely rotating due to the existence of the worm gear that meshes with the ball screw unit, and the container also remains stopped.

Furthermore, when the balance weight is applied to the container in the direction in which the container moves upward, the load on the drive motor when the container is moved up and down can be reduced.

[Effects of the Invention] The effects of the multistage parking apparatus 1 of the present invention, which is achieved by having such a configuration, will be described below. First, in the present invention, since the vehicle A is mounted and the container 4 used for ascending and descending is of a hermetically sealed type, there is no risk that the vehicle A may move and drop from the container 4 during transportation. , Exerts an excellent effect on safety measures. Further, since the drive device 10 is configured by one drive motor M, it is not necessary to pay attention to the synchronization between the motors, which is a problem when a plurality of motors are used, and compared with the case where a plurality of motors are used. Cost reduction.

Further, in the present invention, since the worm gear 15 is interposed between the chain transmission mechanism 20 and the ball screw unit 30, even if there is a possibility that the container 4 may fall freely due to a failure,
Due to the characteristics of the worm gear 15, rotation transmission from the worm wheel 17 side to the worm 16 is not performed, so the screw shaft 33 does not rotate and the container 4 remains stopped at the current position. Therefore, in this respect as well, a useful effect is exhibited in terms of safety measures.

Furthermore, in the present invention, the balance weight W is applied in the direction in which the container 4 moves upward, so that the load on the drive motor M when the container 4 is moved up and down can be reduced. This point is particularly significant in a configuration in which all the screw shafts 33 are rotated by one drive motor M as in the present invention.
