[Detailed description of the device]

[0001]

[Industrial field of application] The present invention is applicable to general households.
The present invention relates to a home parking machine that is used to park a single vehicle vertically.

[0002]

2. Description of the Related Art Conventionally, this type of home parking machine has the following structure. That is, a plurality of struts are erected, a pallet for car support that is guided up and down by the struts is provided, and an electric motor (motor) interlocking with a plurality of ropes is connected to the pallet on the ground side. It was set up and configured.

According to this conventional type, the car is stopped on the pallet at the lower limit, and the rope group is wound by the operation of the electric motor to raise the pallet to the upper limit, and then another pallet is placed below the pallet. By stopping the cars, two cars can be parked one above the other.

As for the safety mechanism against the pallet falling due to the cutting of the rope, a solenoid actuating type locking device and a springback type locking device utilizing the tension of the cord are newly added.

[0005]

In the above-mentioned conventional method, if one of the four locks is not unlocked at the stop position due to malfunction of the solenoid type lock device, for example, only one place of the pallet is locked. And the other three places will go down. That is, it becomes the same as the state in which three of the four cords are cut. This indicates that the safety device becomes unsafe (dangerous) when its failure occurs, which does not improve safety but rather reduces reliability.

An object of the present invention is to provide a highly safe home parking machine which can automatically prevent the pallet from moving up and down when the rope is cut or the column is defective.

[0007]

In order to achieve the above-mentioned object, a household parking machine of the present invention has a plurality of pillars provided upright, and a cylindrical member is externally fitted to these pillars so as to be vertically movable. An eccentric actuation type resin brake metal is provided on the inner surface of which a braking action occurs when an acting load other than the design load is applied, and a pallet for vehicle support provided between the tubular members is provided.
A pair of left and right frames fixed between the front and rear cylindrical members, and a car support portion provided between the left and right frames, and a lifting device that interlocks with the pallet are mounted on the pallet and a drum mounted on the pallet. By the four ropes whose base ends are fixed and guided by the pallet side guide part, and then the free ends are fixed to the upper part of the column, and the electric motor with a brake provided on the pallet side to interlock with the drum. The drum is configured to be wound so that all four cords are pulled so as to pull in a direction opposite to the diagonal line.

[0008]

According to the structure of the present invention, the guide portion is formed by stopping the vehicle on the pallet at the lower limit and rotating the drum by driving the lifting device to wind the four ropes. The length of the upper rope can be gradually shortened and the pallet can be raised. By positioning the pallet at the upper limit in this way, the car can be stopped below the pallet,
Thus, two cars can be parked up and down.

The pallet can be lifted and lowered with almost no shaking due to the resin brake metal slidingly contacting the outer surface of the column, and when the pallet is lifted, a lifting device such as an electric motor with a brake can move up and down with the pallet. .

One of four cords with the progress of use
When three pieces are cut, the hanging force at the cutting part is released and the cutting part tries to descend, but at that time, the pallet tilts and an acting load other than the design load acts on the cylinder member side. As a result, the resin brake metal corresponding to the cut portion is caught (cut into) on the outer peripheral surface of the column, and a braking action is exerted, and the frictional force can automatically prevent the fall (fall).

Further, lowering from this state can be gradually performed while lowering the frictional force by lowering the portion on which the suspension force acts. Furthermore, when the pillar is deformed due to damage with use progress, poor quality during construction, etc.,
Since the resin brake metal cannot pass through this deformed portion, it is possible to automatically prevent the pallet from rising and falling.
