Abstract
A support apparatus for a wheel chock for a trailer, semi-trailer or truck comprising a mobile and articulated arm, affixed to an exterior wall of a loading dock where the extremity supports a wheel chock. A part of the arm, mobile, having its anchor point at the loading dock, is attached by a universal joint to a second section, which is articulated, on which the wheel chock is affixed via a pivot. A recall mechanism assists in the motion and storage of the wheel chock support while ensuring that the chock exerts a pressure on the tire when it is in position under the wheel.
Description
Specification Field of the invention The present invention relates to a support apparatus for a wheel chock for use by businesses at loading and unloading docks for trucks, trailers, and semi-trailers to facilitate the use of chocks and ensure use of chocks by all truckers.
Description of prior art It is customary in the transportation industry to use wheel chocks to prevent accidents that can happen if a truck or a semi-trailer moves during loading. Wheel chocks used in the transportation industry are handled by hand. Practice dictates that they are placed near loading docks and truckers have to take them from their storage space to put them under one or more wheels of their semi trailer or truck. After loading, the trucker has to put the chock back into its storage space. Two problems arise. In some cases, truckers are in a rush and leave the chock on the ground. These chocks can be crushed by the arrival of another semi trailer at the loading dock, or lost during snow removal in the winter. In other cases, truckers simply leave with the chock. The industry has to accommodate a significant number of lost or stolen chocks because there is no system to place the chocks back into their storage space.
Chocks are sometimes heavy and difficult to manipulate. They are often covered in sludge, earth or grease, making many reluctant to use this important safety element at loading docks. If a wheel chock detection system is implemented, truckers often deactivate the system by removing a chock out of its support and simply place it on the ground without putting it under a wheel.
When they are used and the ground is wet, covered by snow or iced over, chocks have a tendency to lose some of their traction and can slide on the ground, which substantially reduces their efficiency and they don't offer the same safety they should.
Summary of the invention According to the present invention, an apparatus to support a chock comprises an articulated and movable arm.
Preferably, a section is attached to the loading dock via an anchor point, at whose extremity is joined a second movable section.
Preferably, at the extremity of the second section, a chock is attached via a pivot.
Preferably, the articulation and mobility of the arm is ensured by a pivot at the anchor point at the loading dock, a universal joint at the point where the two sections of the arm meet, and a pivot at the attachment point of the chock.
Preferably, a recall system, being a spring or a piston, facilitates the manipulation of the arm while ensuring that the wheel chock exerts a pressure on the wheel when it is in position on it.
This system also permits to recall and upkeep of the wheel chock when it is stored in its space.
Description of the drawings Figure 1 is a plan view of the parts that make up the apparatus of the wheel chock support.
Figure 2 is a lateral view of the wheel chock support when the chock is in position under the wheel.
Figure 3 is a lateral view of the wheel chock in storage position.
As described on the drawings, the wheel chock support apparatus is made to help manipulation of the wheel chock and to support it from its storage position to its position under the wheel.
The apparatus comprises two sections, (4) and (6), joined by a universal joint (5) that permits gyratory motion of section (4) supporting the wheel chock (1). Section (6) is attached to the anchor system (9) by a pivot (8) that allows up and down movements. At the extremity of section (4), a wheel chock (1) is attached via a pivot (2) that permits up and down movements of chock (1). Spring (7) is attached by one extremity to loading dock wall (10) and by the other extremity to universal joint (5), and can be removed to let section (4) to be disassembled without breaking off the arm when the arm is fully extended. Spring (7) also provides useful recall force when truckers handle the support by exerting a recall force on chock (1) to provide holding force on tire (3) when it is in position, and permits the support to remain in storage position when not in use, as well as avoiding slippage. Handle (11) facilitates movement of the chock support.
It goes without saying that the present invention should not be considered as limited to the described mode, and covers all variations thereof.
