Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides nut members on both left and right sides of a vehicle mounting platform that are screwed into threaded rods that are installed on both the left and right sides, two at the front and back. , concerning a simple elevating parking device in which a vehicle mounting platform is raised and lowered through each nut member by rotation of each threaded rod driven by an electric motor, and in particular, power transmission from the electric motor to each of the four threaded rods. It is about the mechanism.

[Prior art] This type of elevating parking device uses four screw rods, and the front and rear screws are interlocked by a bevel gear mechanism and a shaft member, and the left and right shaft members are interlocked by a chain sprocket mechanism. A connected structure is known from Japanese Utility Model Publication No. 52-8226. Each threaded rod is assembled into an individual gear box, and an electric motor is operatively connected to the -threaded rod.

[Problems to be Solved by the Invention] However, one end of the left and right shaft members is inserted into one gear box and is provided with a bevel gear, and a chain sprocket mechanism is configured between the left and right shaft members. Therefore, when changing the size of the vehicle platform to accommodate vehicles of different sizes, such as light vehicles, small vehicles, and large vehicles, the following problems arise.

In other words, it is necessary to change the position of the threaded rod depending on the size of the vehicle platform, but since one end of the left and right shaft members is inserted into one gear box and is equipped with a bevel gear, it is necessary to change the position of the threaded rod depending on the size of the vehicle platform. First, the left and right gear boxes on one end side and the bevel gear mechanism inside must also be specially prepared, and since the chain sprocket mechanism is installed between the left and right shaft members, it is a troublesome work to hang the chain. It also became something that had to be done.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to share a gear box in which four threaded rods are incorporated and its internal gear mechanism, while changing the position of a threaded rod in accordance with the size of a vehicle platform. To provide an elevating type parking device which can be easily adapted by simply changing a shaft member provided between boxes.

[Means for Solving the Problems] In order to achieve the above-mentioned problems, the present invention provides two threaded rods (front and rear) on both left and right sides of a vehicle platform, and a nut member that is screwed onto each threaded rod. are provided on both the left and right sides of the vehicle platform, and the vehicle platform is raised and lowered through each nut member by rotation of each threaded rod driven by an electric motor. are individually assembled into gear boxes, the input and output parts of the gear mechanism in each gear box are respectively protruded to the outside of each gear box, and the electric motor is interlocked and connected to the input part protruding from one gear box. , a shaft member is installed between the input and output parts protruding from each gear box.

[Function] Since the input and output parts of the internal gear mechanisms protrude outward from each gear box into which the four threaded rods are individually installed, the threaded rods can be adjusted according to the size of the vehicle platform. When changing the position, this can be easily done by simply changing the shaft member installed between the input and output parts protruding from each gear box, and each gear box and its internal gear mechanism can be shared.
