Abstract
A bracket is disclosed for removably hanging items on a wall and
in its preferred embodiment is particularly adapted for use with
so-called "pegboard" type storage units. The bracket has a support
member with a pair of spaced ears at the top for securement to the
wall. The bracket also has a hanger member incorporating a pair of
spaced, article clamping arms and a connecting portion which, at
the rearward end of the arms, passes around behind the support
member and adjacent the center of the bracket seats against and is
secured to the front face of a central depending portion of the
support bracket whereby the spacing between the arms can be varied
by flexing the arms adjacent their attachment to said support. The
lower end of the depending center portion is offset rearwardly to
seat against the wall with the arms extending normal to the wall;
the bracket being so constructed that no welded connection between
its parts is loaded in tension.

Description
FIELD OF THE INVENTION
The invention is a bracket designed to be secured to a vertical
surface such as a pegboard to provide means of detachably
supporting and storing an object such as a jar, can or other
container. The bracket provides a support which will detachably
support the jar or other container, yet, permit quick mounting or
removal of the object. The invention is designed to provide a
bracket which will readily adjust itself to containers of various
sizes. The bracket is specifically designed when used with pegboard
to overcome the problem of the bracket becoming detached from the
board when the containers are attached or removed. It is also
designed to overcome the problem of bracket weakness, yet permit
the use of a minimum of materials.
BRIEF DESCRIPTION OF THE INVENTION
The bracket of this invention consists of two parts, a support
element and a hanger element. The hanger element has a pair of
clamping arms designed to be capable of resiliently spreading
sufficiently to receive and then clamp the container. These arms
are joined by a connecting portion which is shaped to partially
wrap about the support element. The support element is designed to
be secured to the supporting surface such as a pegboard or wall and
to hook around the rearward end of the support bracket and have a
central portion which extends downwardly to provide a stabilizing
foot or leg. This foot or leg extends behind the central connecting
portion of the hanger bracket. At this point only, the two elements
are rigidly connected. This arrangement permits the arms to
resiliently flex about a point adjacent the center of the bracket,
thus relieving the juncture of the arms and the connecting portion
from the bending strain normally imposed at this juncture. This
also provides a bracket having three-point contact with the
supporting surface to stabilize it against vertical loads.
These and other objects and purposes of the invention will be more
fully understood upon reading the following drawings and detailed
description.

DESCRIPTION OF THE PREFERRED EMBODIMENT
The bracket 10 has two components, a support element 11 and a
hanger element 12. These two elements are preferably made from a
suitable spring-like material such as steel wire or small diameter
rod. The material must be resilient in the sense that it must be
capable of limited spring action and provide sufficient resistance
to deflection that it will not deform under normal loading but will
permit the bracket to be snapped around a container and firmly and
positively clamp the container.
The support element 11 is a single piece having a pair of laterally
spaced end portions joined by a connecting portion 14. The end
portions 13 are generally L-shaped providing a pair of upstanding
ears 15 and a pair of generally forwardly extending leg portions
15a. The connecting portion 14 extends inwardly, i.e., toward the
vertical centerline of the bracket, and the midsection is formed
into a deep, depending, generally U-shaped loop 16. The bottom of
the loop is closed and the sides of the loop, adjacent the bottom,
are generally parallel and vertical. The lower portion of the loop
16 is offset rearwardly a distance and for a purpose which will be
subsequently explained. The upwardly opening slot 17 formed by the
loop 16 is preferably of a width suitable for insertion of a screw
between the sides.
The hanger bracket 12 is also of one-piece construction and is
generally U-shaped in plan view having a pair of forwardly
extending arms 20, joined at their rearward ends by a connecting
portion 21. As viewed in elevation from the front, the connecting
portion 21 is shaped into a downwardly extending shallow V. At the
juncture of each of the arms 20 and the connecting portion 21, the
hanger element passes around the rear face of the support element
11 at the juncture of the end portions and the connecting portion
14. The middle of the connecting portion 21 is offset forwardly to
pass in front of and bear against the front face of the depending
loop 16 of the support element 11. The points of contact between
the connecting portion 21 and the loop 16 are located substantially
below the plane of the arms 20 and a short distance above the
closed bottom of the loop 16. At the points of contact between the
loop 16 and the connecting portion 21, the two elements are rigidly
joined together by suitable means such as welding 22. It will be
observed that the loop 16 is relatively narrow and, thus, the
points of welded attachment are closely adjacent the vertical
centerline of the bracket.
The ends of the arms 20 are inwardly offset at 23 to provide
lip-like structure for positively holding a container inserted
between them. Forwardly of the offsets 23, the ends of the arms are
flared laterally to facilitate the entry of a container between
them. FIG. 3 illustrates the bracket when the arms are in their
normal position. FIG. 4 illustrates the bracket with the arms
spread apart as though they were clamped about a container seated
between them which is somewhat larger than the normal spacing
between the arms. It will be observed in FIG. 4 that when the arms
20 are forcibly spread apart, the hanger bracket 10 does not flex
about the juncture between the arms 20 and the central connecting
portion 14 but rather about a point immediately adjacent the welds
22 where the support and hanger elements are joined. This is
important because it eliminates the stress fatigue which would be
experienced were the arms forced to flex about the juncture. Also,
without sacrificing the clamping or holding ability of the hanger
element 10, the degree to which the arms 20 can be reasonably
separated is significantly increased. Thus, the bracket may be used
to support containers of a substantially greater range of sizes
than would otherwise be possible. Also, by extending the central
connecting member 21 downwardly, the point of connection between
the support bracket and the rearward end of the arms is increased,
further increasing the range of permissible flexing of the arms to
accommodate containers of various sizes.
The bracket is shown mounted to a typical pegboard wall in FIG. 1.
As shown in FIG. 5, the pegboard 30 is of conventional design
having a plurality of equally spaced openings 31 arranged in both
vertical and horizontal rows. In FIG. 1, an ear 15 is shown
inserted through one of the holes 31 with the front or forward face
of the ear 15 seated against the inside surface of the pegboard 30.
This is a conventional means of securing a bracket to a pegboard.
The downward pivoting of the bracket about the ear 15 is limited by
the lower end of the loop 16 seating against the outer or front
face of the pegboard. Preferably, the arrangement is such that when
the bracket is stable, the arms 20 are normal to the front face of
the pegboard and, if the pegboard is vertical, the arms will be
horizontal.
Since the juncture between the arms 20 and the connecting portion
21 of the hanger element 12 is seated behind the support element 11
at the juncture of the legs 15a and the connecting portion 14, it
is necessary that the lower portion of the loop 16 be offset
rearwardly at least the thickness of the hanger element where the
latter passes behind the support element, if the arms 20 are to be
maintained in horizontal position.
FIG. 6 illustrates the fact that the bracket of this invention can
be modified, without in any way changing its principles of
construction, to accommodate narrow objects such as a hammer
handle. In this case, the arms 20a of the bracket 10a are offset
inwardly immediately forward of the support bracket to provide a
narrowed article receiving slot 40. The same principle of
attachment to the front of the support element closely adjacent the
bracket centerline is maintained, thus, retaining all of the
advantages of adjustability and strength. By retaining the wide
spacing between the ears 15, lateral stability is retained along
with the increased degree of flexibility of the arms 20a.
It will be observed by this arrangement, that a particularly strong
bracket is produced. The torsional loads imposed by the weight of a
container such as the container A tend to pivot the bracket about
the point of contact between the ears 15 and the back face of the
board 30. In doing so, they impose a tension load on the top
connection between the hanger element 12 and the support element 11
and this is absorbed by the hanger element passing behind the
support element and thus engaging the support element in bearing.
Thus, no fastener or welded connection is placed in tension which
might ultimately break. At the same time, the rearwardly acting
forces of this force couple are transmitted from the hanger element
12 to the support bracket at the points of weld 22. Here the forces
are again acting in compression or bearing and thus, the welds are
relieved of any tension or torsional loads. Once again, the
construction of the bracket makes it capable of substantially
higher loadings than would be possible were these loads imposed
across a weld or the like in tension or torsion.
If it is desired to positively stabilize the bracket against any
kind of tipping during the insertion or removal of the containers,
a screw 40 (FIG. 1) can be installed at the bottom of the loop 16.
Preferably, this screw can be threaded into one of the holes 31 of
the pegboard. The bracket can be so designed that the ears 15 are
spaced to seat in alternate holes such as the holes 31a and 31b
with the screw inserted in the hole 31c midway between the holes
31a and 31b in the next lower row of holes as is suggested in FIG.
5.
It will be recognized that if this bracket is not to be used with a
pegboard-type structure, eyelets could be substituted for the ears
15 to receive screws which are inserted into the wall
structure.
It will be seen that this invention provides a very simple, strong
and inexpensive bracket. The two components of the bracket can be
formed from wire or small diameter rod by suitable means such as a
wire wrapping machine or by suitable dies. The assembly consists
simply of interlocking the two elements and welding them together.
Because of the construction of the bracket, it is substantially
free of possible failure due to fatigue and is capable of
sustaining significantly higher loading than presently existing
brackets designed for the same purpose.
While a preferred embodiment of this invention has been described,
it will be recognized that various modifications may be made
without departing from the principles of the invention and such are
to be considered part of the invention.
