Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a bracket construction for the wall
mounting of cabinets.
2. Description of the Prior Art
Brackets for the wall mounting of cabinets have heretofore been
provided. However, with such brackets it has been necessary to
precisely position the brackets on the wall to make it possible to
precisely position cabinets on the wall and in particular to place
a row of cabinets at the same level or height. There is a need for
a new and improved bracket construction which does not require such
a precise positioning of the bracket.
SUMMARY OF THE INVENTION AND OBJECTS
The bracket construction for the wall mounting of cabinets
comprises a relatively rigid member adapted to be secured to the
wall. An additional rigid member is provided. The first-named and
additional rigid members are each provided with a pair of slots
which are formed therein. The slots in one of the members are
inclined at an angle with respect to the slots in the other of said
members. Releasable securing means is provided which extends
through the slots in the first-named and additional members for
removably securing the additional member to the first-named member
whereby said slots permit adjustment of the additional member
relative to the first-named member.
In general, it is an object of the present invention to provide a
bracket construction which is particularly adapted for readily
mounting cabinets on a wall.
Another object of the invention is to provide a bracket
construction of the above character by which it does not require
the portion of the bracket construction mounted on the wall to be
precisely positioned.
Another object of the invention is to provide a bracket
construction of the above character which permits adjustment of the
position of the cabinet on the wall.
Another object of the invention is to provide a bracket
construction of the above character which substantially reduces the
mounting time required by the installer of the cabinets.
Another object of the invention is to provide a bracket
construction of the above character which facilitates mounting of
cabinets on walls which are not absolutely flat or planar.
Additional features and objects of the invention will appear from
the following description in which the preferred embodiment is set
forth in detail in conjunction with the accompanying drawing.

DESCRIPTION OF THE PREFERRED EMBODIMENT
The bracket construction 11 is adapted to be mounted on a wall 12
and is utilized for securing cabinets such as cabinet 13 to the
wall. The wall 12 can be of any conventional type, as for example,
as shown on the drawings it can consist of spaced parallel vertical
studs 14 to which there has been secured plaster board 16 in a
conventional manner. The plaster board 16 provides an outer wall
surface 17 which is generally planar and extends in a vertical
direction.
The bracket construction 11 consists of a relatively rigid plate or
member 21 and an additional rigid member 22. Both the members 21
and 22 can be formed of suitable materials. For example, the member
21 can be formed of steel whereas the member 22 can be formed of
plywood, Masonite or other materials of which cabinets are made. As
hereinafter described, it is preferable that the member 22 form the
rear wall of the cabinet 13 which is to be mounted upon the wall
12.
Each of the members 21 and 22 has two slots which are formed
therein, with the slots in one of the members being inclined at an
angle with respect to the slots in the other of the members. Thus,
as shown in the drawing, the member 21 is provided with two slots
23 which are in axial alignment and which extend in a generally
horizontal direction when the member 22 is secured to a wall. The
slots 23 are of substantial length and preferably are of such a
length so they extend over at least one-half of the member 22 but
to a distance which does not impair the structural rigidity of the
member 21.
The member 21 can have any desired shape, as for example, the
rectangular configuration shown in FIG. 2 and should have a length
which is greater than the spacing between two adjacent studs 14.
The member 21 is provided with front and rear surfaces 24 and 26.
The member 21 is also provided with a recess 27 which is formed by
a U-shaped portion extending longitudinally of the member 21 and
spaced equi-distant between the upper and lower extremities
thereof. The member 21 is also provided with a plurality of
additional smaller slots 28 which are generally spaced over the
surfaces 24 and 26 of the member 21. As can be seen, particularly
in FIG. 2, the slots 28 extend in two rows with two rows above and
two rows below the two slots 23 in such a manner that the slots in
one row of each of the two rows are staggered with respect to the
slots in the other row. The member 22 is also formed with open
ended slots 29 provided in opposite ends of the member 21. The
member 21 is adapted to be secured to the wall 12 by suitable means
such as screws 31 which extend through the slots 28 to removably
secure the member 21 to the studs 14.
As also shown on the drawing, the member 22 is provided with a pair
of slots 32. The slots 32 are inclined at an angle with respect to
the horizontal and also with respect to the vertical. By way of
example, the slots can be inclined at an angle of 20.degree. from
the horizontal and if desired can have an angle ranging between
10.degree. and 30.degree. from the horizontal. In the embodiment
shown in the drawings, the slots 32 are inclined upwardly and in an
outward direction. The slots 32 and the member 22 and the slots 23
and the member 22 have the same general positions and spacing
between them with the principal difference being that the slots 32
are inclined at an angle with respect to the slots 23. The slots 23
and the slots 32 also have approximately the same width and
length.
As can be seen from FIG. 1, the member 22 serves as a rear wall for
the cabinet 13 which includes spaced parallel side walls 36 and 37,
top and bottom walls 38 and 39 and a front wall formed by a pair of
hinged side swinging doors 41. The cabinet is constructed in such a
manner that the rear wall formed by the member 22 is slightly
recessed with respect to the rearmost extremities of the side walls
36 and 37 and the top and bottom walls 38 and 39 to accommodate the
bracket construction which is utilized for mounting the
cabinet.
Releasable securing means which is adapted to extend through the
slots 23 and 32 of the members 21 and 22 is provided for securing
the additional member 22 to the first-named member 21. This
releasable securing means consists of a pair of screws 43 each of
which is provided with generally flat rounded head portions 43a
which is offset slightly from the center of the threaded stem
portion 43b of the screw. The screw is also provided with outwardly
extending ear-like portions 43c underlying the head portion 43a and
being formed integral with the head portion 43a and the stem
portion 43b. The heads of the screws are adapted to seat within the
recess 27 provided in the member 21 and extend through the slots
23. When the member 21 is secured to a wall as shown in FIG. 1, the
screws 43 are retained between the member 21 and the wall and are
held in position. They are prevented from turning in the slots 23
by the ear portions 43c. The screws are also adapted to extend
through the slots 32 of the member 22 of the cabinet. A washer 44
formed of a suitable resilient material such as foam rubber is
adapted to be mounted upon each of the screws 43 between the member
21 and the member 22. The releasable securing means also includes
means in the form of wing nuts 46 and washers 47. The cabinet can
be readily held in place by screwing the wing nuts 46 onto the
screws 43.
Use of the bracket construction for the mounting of wall cabinets
may now be briefly described as follows. Let it be assumed that it
is desired to mount a plurality of cabinets at the same height from
the ceiling or floor of a room and in a row. This is accomplished
by the installer by first generally ascertaining the positions for
the brackets which are to be utilized for mounting the cabinets.
The installer first marks the approximate positions for members 21
of the bracket construction for mounting upon the wall. The
installer then without great precision can readily secure the
members 21 to the wall by suitable means such as screws 31. After
the members 21 are firmly secured, the first cabinet is hung on the
wall by removing the wing nuts 46 and the washers 47 from the
screws 43 and positioning the cabinet so that the screws 43 extent
through the slots 32. The washers 47 and the wing nuts 46 are then
placed on the screw so that the cabinet 13 is held in the general
desired position. Therefore, the cabinets can be precisely
positioned in the desired location by shifting the screws in the
slots 23 and 32 in a horizontal direction and making it possible to
precisely position the cabinet in a horizontal direction. At the
same time, the cabinet can be shifted vertically as permitted by
the inclined slots 32 so that the cabinet is in the desired
vertical location.
After the cabinet has been positioned vertically and horizontally,
the wing nuts 47 are tightened to firmly hold the cabinet in place.
It will be noted as shown particularly in FIG. 5 that the bracket
construction is recessed in the space provided behind the cabinet
and for this reason it is possible to mount the cabinets flush to
the wall with the rear extremities of the side walls 36 and 37 and
the top and bottom walls 38 and 39 being flush with the wall. In
the event that the wall surface 17 is not exactly planar, the
mounting provided by the bracket construction including the
resilient washers 44 provides in general a three-point mounting for
the cabinet in which the bracket construction serves as one point
and two of the walls serve as two of the other points.
In this manner it can be seen that it is unnecessary for the
installer to precisely position the member 21. It is only necessary
that it be positioned in the general location and then the desired
precise positioning for the cabinet can be obtained by shifting the
cabinet relative to the member 21 to the desired position in two
directions at right angles to each other as permitted by the slots
23 and 32 and then fastening the cabinet in the desired place by
the wing nuts 46.
With the foregoing bracket construction it can be seen that the
height of the cabinet can be varied by the distance between the
upper and lower ends of the inclined slots provided in the
additional member. By way of example, one-half inch should be more
than adequate to give more than adequate leeway to the mounting of
the first-named member on the wall and still permitting the
cabinets to be all aligned in a row on a wall of a room.
As soon as one cabinet in a row of cabinets has been installed, the
other cabinets can be readily positioned in the same manner by the
utilization of a level using the first installed cabinet as a
reference. In this way, it is possible to provide a perfectly
aligned row of cabinets with very little effort.
Although the bracket construction has been described for use in
connection with the mounting of cabinets, it is readily apparent
that if desired other items can be mounted on walls by use of such
a bracket construction.
It is also apparent from the foregoing that there has been provided
a bracket construction which makes it very easy for the installer
to install cabinets on the walls without the necessity for
precisely mounting the mounting plates or brackes which are
utilized for securing the cabinets to the wall. The bracket
construction is very neat in appearance and is concealed from view
of the user. The bracket construction also makes it possible to
readily remove the cabinets from the wall if they are no longer
desired. The bracket construction also facilitates rearrangement or
exchange of cabinets from one cabinet hanging space to another.
