WALL BRACKET FOR GARAGE DOORS AND THE LIKE
Field of the invention:
The present invention relates to a wall bracket for garage doors and the
like. More particularly, the present invention relates to a wall bracket for
use with a
door, such as a garage door for example, and for possible interaction also
with the
counterbalancing system thereof.
Background of the invention:
Sectional doors, rolling doors and cable-operated doors, such as
garage doors and the like, are well known in the art. A garage door is usually
connected to an overhead mechanism that provides a driving or counterbalancing
force in order to decrease the force required to open the door and also
facilitate its
closing.
it is also known in the art that a garage door generally needs to have a
proper counterbalancing system so that it may be easily opened and closed. The
counterbalancing force is generally achieved by the usage of either one or
many
torsional springs, or by any other suitable biasing means, such as
counterweights
for example.
It is also well known in the art that a garage door, the components
thereof, and/or the components of a corresponding counterbalancing mechanism,
are generally supported onto a fixed structure, such as a wall for example, by
means of support plates, cammoniy known as "wall brackets". These wall
brackets
are intended to support the weight of the garage door and of all the different
components operatively connected thereto and are thus subject to substantial
loads, and also various repeating loading conditions due to the inherent
nature of
the raising and lowering of garage doors. Consequently, as a result thereof,
it has
been found that these wall brackets generally have a tendency to warp or
deform

themselves, thus leading to a series of adverse consequences, such as
inefficient
operation of the garage door andlor corresponding counterbalancing mechanism,
fatigue stresses resulting in the wall brackets leading possibly to a failure
or an
unsafe condition thereof, and the like. Consequently, the wall brackets may
need
periodic inspection andlor maintenance, and may require replacement, which is
very disadvantageous for different reasons.
Hence, in light of the aforementioned, there is a need for an improved
wall bracket which, by virtue of its design and components, would be able to
overcome some of the aforementioned prior art problems.
Summary of the invention:
The object of the present invention is to provide a wall bracket which
satisfies some of the above-mentioned needs and which is thus an improvement
over the other related wall brackets known in the prior art.
In accordance with the present invention, the above object is achieved,
as will be easily understood, with a wall bracket provided with at least one
embossment such as the ones briefly described herein and such as the ones
exemplified in the accompanying drawings.
According fio another aspect of the invention, there is also provided a
driving (or "counterbalancing") mechanism provided with the above-mentioned
wall bracket.
According to yet another aspect of the invention, there is also provided
the garage door provided with the above-mentioned wall bracket.
According to yet another aspect of the invention, there is also provided

Some of the wall brackets 1 shown in the accompanying figures are
"right" wall brackets 1 to be located at the "right" of the garage door, more
specifically at the right-hand side thereof when viewed from the inside of the
garage. A "left" wail bracket 1, that is, a left-hand side version of the
brackets 1
shown, would simply be a mirror image of what is in the accompanying figures,
and vice versa. Each wall bracket 1 with corresponding embossment 3, whether
right or left wall bracket 1, is preferably devised to hold at least half of
the load of
the garage door and corresponding components operatively connected thereto,
and is preferably securely affixed to a fixed structure, such as a wall for
example,
