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

CA 02164738 2008-04-17
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.
