Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wheel chock device used in a multi-level parking device that has an upper pallet that rises from the ground surface and is capable of parking above ground and underground.

[Conventional technology]

Conventionally, as a device that prevents vehicles on the upper pallet from moving spontaneously due to forgetting to apply the handbrake, etc., the present applicant has provided a wheel stop device as described in Japanese Utility Model Application Publication No. 167154/1983. are doing. This device uses a bracket whose tip slides on the back of the wheel stop plate when the shaft rotates in the forward direction, and tilts the wheel stop plate. When the lower end collides with the road board, the lever is lifted upwards against the repulsive force of the spring, and the shaft is rotated in the opposite direction to make the wheel stop plate parallel to the upper pallet. It was possible to take things in and out.

[Problem that the invention attempts to solve]

The above method using a bracket that slides on the back side of the wheel stop plate has a large sliding part that is mechanically unstable, so it is necessary to use a spring to rotate the wheel stop plate upward when the upper pallet (elevating body) is raised. The repulsive force had to be increased in order to increase the reliability of the movement. Therefore, in order to reduce the sliding friction between the wheel stopper plate and the end of the bracket, measures such as installing a roller at the end of the bracket, separating the lever and bracket, and adding an auxiliary spring to connect them with elasticity have been devised. was necessary. Therefore, the upper pallet (elevating body)
In order to ensure that the wheel stop plate is tilted at a predetermined angle in order to prevent the wheel from climbing over the vehicle when the vehicle is raised, many parts are required, which is time consuming to manufacture and increases costs.

The present invention is an attempt to solve the above-mentioned problems, and provides a wheel stopper device for a multi-level parking system in which the wheel stopper plate rotates reliably with a small force and a small number of parts by eliminating the sliding part. This is what I am trying to do.

[Means for solving problems]

In order to eliminate the above-mentioned problems, the present invention includes a wheel stop plate that is provided at approximately the wheel rest position on the upper surface of the upper pallet that rises from the ground surface, and whose end opposite to the wheel rest position is attached to the shaft. A spring that urges the shaft so that the plate rotates upward from the upper surface of the upper pallet, a stopper that restricts the upward rotation of the wheel stop plate biased by the spring, and a stopper that restricts the upward rotation of the wheel stop plate when the upper pallet is lowered to the lower end. The link device includes a link device that contacts a stationary portion provided approximately on the ground surface and rotates the shaft by the weight of the upper pallet against the elastic force of the spring.

[Effect]

According to the present invention, the number of parts of the device can be reduced and the device can be configured to be easily assembled.

That is, a wheel stop plate 4 whose wheel 2 side rotates upward is provided on the upper surface of the upper pallet 1 rising from the ground surface at a substantially wheel rest position. The wheel stop plate 4 is a stopper 6 provided on the wheel stop plate 4 itself or on the shaft 3, link device 5, etc.
The upward rotation is restricted by the spring 7.
It is always urged to rotate upward at a constant angle due to the repulsive force. In this case, even if the wheel 2 moves in the unloading direction, only the tip of the wheel stopper plate 4 comes into contact with the wheel 2, acting like a brace. It can be significantly smaller than when attached to the shaft, and there is no need for reinforcing members, reducing the number of parts.
Cost reduction can be achieved. Next, when the upper pallet 1 is lowered, the drive lever 1 constituting the link device 5 is moved to the stationary part 8 provided approximately on the ground surface.
The contact portions 15a of 6 contact and receive the weight of the upper pallet 1 etc., and the driving force conversion portion 15b and the connecting bar 1
8. Rotate the shaft 3 against the elastic force of the spring 7 via the rotation lever 14 so that the wheel stopper plate 4 is parallel to the upper surface of the upper pallet 1, and when the upper pallet 1 is lowered to the unloading position. The wheels 2 can ride over the wheel stop plates 4. Further, when the elevating body b rises and begins to move upward, the wheel stop plate 4 is rotated upward again by the elastic force of the spring 7 to face the wheel 2 and prevent the wheel 2 from running over. Furthermore, a fixed wheel stop plate 11 is provided in advance at the rear of the wheel 2 to prevent the wheel 2 from climbing over the upper pallet 1, and to prevent the wheel 2 from slipping out of a predetermined position when the upper pallet 1 is rising. act.

Fig. 2 is a plan view of the wheel locking device of the present invention, and Fig.
FIG. 3a is a sectional view taken along the line XX in FIG. 2, FIG. 3b is a sectional view taken along the Y-Y line in FIG. 2, and FIG. 3c is a sectional view taken along the Z-Z line in FIG.

In FIG. 2, at a substantially wheel rest position on the upper surface of the upper pallet 1, there is a shaft 3 extending into the inside of a wheel guide 12 whose outer end is raised one step higher on the side of the upper pallet 1, and is rotatable by a presser 31. It is set in. A wheel stop plate 4 on the vehicle loading/unloading side is integrally attached to the shaft 3 as shown in FIG. 3a. Reference numeral 30 indicates a cushion rubber provided above the upper pallet 1 in order to absorb the pressing force and vibrations applied when the wheel 2 tries to get over the wheel stopper plate 4.

Further, the spring 7 is wound around the shaft 3, and one end is engaged with a spring engagement part 13a provided on the upper pallet 1, and the other end is engaged with a spring engagement part 13b provided integrally with the shaft 3. The wheel stop plate 4 is urged to rotate upward by resiliently repelling the space between the wheels.

Further, as shown in FIG. 3a, the stopper 6 also serves as the end of the wheel stopper plate 4 on the shaft 3 side, and when the wheel stopper plate 4 rotates upward, the shaft 3
Rotation of the wheel stopper plate 4 and the shaft 3 is restricted by the side ends coming into contact with the upper surface of the upper pallet 1.

The link device 5 is connected to the outer end of the shaft 3 as shown in FIG. A drive lever 16 that drives the lever 14 and a connecting lever 1 that connects them
It consists of 8.

The drive lever 16 has a stationary part 8 provided on the ground surface, for example, a contact part 15a that contacts a road board for people to drive in and out of a car, and a contact part 15a that is approximately perpendicular to the contact part 15a. It has a driving force converting part 15b which is integrally formed and converts the vertical movement of the contact part 15a into lateral movement.

Further, the connecting bar 18 is divided into parts, and a turnbuckle 19 is provided therebetween for mutually adjusting the positions of the rotating lever 14 and the driving force converting portion 15b of the driving lever 16.

That is, the turnbuckle 19 rotates the wheel stop plate 4 upward by a predetermined angle when the elevating body b and the upper pallet 1 are ascending, and adjusts the wheel stop plate 4 so that it becomes parallel to the upper surface of the upper pallet 1 when descending. This makes assembly easy even if there are errors in the mounting positions or dimensions of each component.

In the present invention having the above structure, when the elevating body b and the upper pallet 1 are raised, the wheel stop plate 4 is rotated upward via the shaft 3 by the force of the spring 7, and the upward rotation is restricted by the stopper 6, and the wheel stop plate 4 is rotated upwardly by the force of the spring 7. This makes it impossible for the wheel 2 to cross over.

Next, when the elevating body b and the upper pallet 1 are raised and lowered for unloading, etc., the contact portion 15a of the drive lever 16 comes into contact with the stationary part 8 provided approximately on the ground surface, and the lowering body b and the upper pallet 1 are moved up and down. Rotated under the weight of the first class, the driving force conversion part 15b, the connecting bar 18,
The shaft 3 is rotated via the rotation lever 14 against the elastic force of the spring 7, and the wheel stop plate 4 is rotated.
is parallel to the upper surface of the upper pallet 1, allowing for unloading.

A three-stage parking device is shown in FIGS. 4 and 5.

This parking device does not have an elevating body b like the above-mentioned two-tier parking device, but has an upper pallet 41 and a lower pallet 42 which are configured to be able to rise and fall freely, and which run horizontally on a transverse rail 44 provided approximately on the ground surface. It has a middle pallet 43, and an appropriate number of pallets are installed together.

Then, the middle pallet 43 provided at the loading/unloading position is moved sideways and the upper pallet 41 is lowered into the empty middle pallet 43, or the lower pallet 42 is raised.

The present invention is installed on the upper pallet 41.
In that case, as shown in FIG. 5, the contact portion 15a of the drive lever 16 is configured to come into contact with the transverse rail 44.

[Effect of idea]

In the present invention, the upward rotation direction of the wheel stopper plate is opposite to the conventional direction. As a result, as usual,
This eliminates the need to strengthen the elasticity of the spring or provide various parts, making manufacturing easier and reducing costs.
