Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a wheel stopper device for use in a multi-tiered parking system having multi-tiered parking pallets that are raised or lowered to a loading / unloading position such as a ground surface.

[Conventional technology]

Conventionally, as a device in which a car on an upper parking pallet does not move naturally due to forgetting to apply a side brake, the applicant of the present application has proposed a wheel stop device and an actual wheel stop device described in Japanese Utility Model Publication No. 63-4144. There is provided a wheel stopper device described in Japanese Patent Laid-Open No. 63-148756.

In these devices, when the upper parking pallet is lifted from the ground surface at the loading / unloading position, the car stop plate rotates upward to prevent the wheels from getting over, and the upper parking pallet reaches the above ground surface. When lowered, the car stop plate becomes parallel to the upper parking pallet so that the car can be taken in and out by overcoming the car stop pallet.

However, all of these devices can be used only for the upper parking pallet that can be lifted and lowered only above the ground surface.For example, an elevator consisting of upper, middle and lower parking pallets can be lifted from the underground storage to the ground. A parking pallet that moves up and down with respect to the ground surface, which is the loading and unloading position, like the middle parking pallet in the three-tiered parking device configured as described above (see, for example, Japanese Utility Model Laid-Open No. 1-76959). Had the drawback that it could not be used. In addition,
From the viewpoint of safety, the middle parking pallet and the like also require a wheel stopper device like the upper parking pallet.

[Problems to be solved by the device]

The present invention has been made in view of the above circumstances, and is used not only for an upper parking pallet that moves up and down only from a loading / unloading position, but also for a parking pallet that moves up and down with respect to a loading / unloading position such as a middle parking pallet. You can, and
An object of the present invention is to provide a wheel stop device that has a simple structure and is inexpensive.

[Means for solving the problem]

In order to solve the above-mentioned problems, the present invention provides a wheel stopper plate which is provided substantially at a wheel stationary position on the upper surface of a parking pallet and has a shaft wheel stationary position which is rotatable with respect to the parking pallet and an end opposite to the wheel stopper plate. A spring for urging the wheel stopper plate to rotate upward from the top surface of the parking pallet, a first lever fixed to the shaft, and a shaft pivotally supported on the parking pallet side to insert the parking pallet. When reaching the exit position, a second lever that rides on a kicker provided on the stationary portion side and rotates, and one end is fixed to the first lever and the other end is the second lever. A first string member fixed to one side position of the lever with respect to the shaft fulcrum, and one end fixed to the first lever and the other end of the second lever with respect to the shaft fulcrum of the second lever. Rank In which was formed from a second string member which is fixed to the.

The string member in the present invention refers to a member that can be stretched and loosened, for example, a chain, a wire, or a link rod in which the middle is foldably connected.

[Action]

According to the present invention, when the parking pallet is located above or below the loading / unloading position, the second lever does not ride on the kicker, so that the force of the spring causes the wheel stopper plate to move to the predetermined position. Is rotated upward to the position of, the first string member and the second string member are both extended, and the second lever is rotated to a predetermined reference position for balance,
That state is maintained. In this way, since the wheel stopper plate is kept in the state of being rotated upward to the predetermined position, the wheel stopper plate prevents the wheel from getting over.

When the parking pallet reaches the loading / unloading position from below, the second lever rides on the kicker from below and pivots to one side, whereby the first string member (or the second string member).
If the second pallet member (or the first tie member) is slackened while the second pallet member is pulled toward the second lever side, and the parking pallet reaches the loading / unloading position from above, The lever rides on the kicker from above and rotates to the other, whereby the second string member (or the first string member) is pulled toward the second lever side and the first string member (or the second string member). The string member) loosens, and in any case, the wheel stopper plate is rotated downward against the force of the spring by the first string member or the second string member pulled toward the second lever. As a result, the wheel stop plate becomes parallel to the parking pallet, and the vehicle can be taken in and out by passing over the parking pallet.

As described above, according to the present invention, when the parking pallet is positioned above or below the loading / unloading position, the wheel stopper plate is rotated upward to a predetermined position, and the parking pallet is moved upward and downward. Since the wheel stopper plate is parallel to the parking pallet when it reaches the loading / unloading position from below, the wheel stopper device of the present invention can be used not only for the upper parking pallet that moves up and down only from the loading / unloading position, but also for the middle parking pallet. It can also be used for a parking pallet that moves up and down with respect to the loading / unloading position.

Further, since the present invention includes the shaft, the wheel stopper plate, the spring, the first and second levers, and the first and second cord members, the structure is simple and can be provided at low cost.
