REVERSIBLE CABINET SHELF BRACKET
Abstract
A bracket for supporting cabinet shelves is secured to the
cabinet side wall and is rotatable angularly through 180.degree.
between two positions. In one, a pin on the bracket extends
upwardly and is insertable in a shelf socket for releasably
interlocking the shelf to the cabinet side wall. In the other, the
pin extends downwardly in a disengaged condition, permitting free
separation of the shelf from the cabinet side wall. In both
positions of the pin, the shelf is supported by the bracket in
substantially the same horizontal plane.

Description
Although many types of cabinet shelf-support brackets heretofore
have been devised, the need exists for a bracket which is useful in
knock down cabinet assemblies for adjustably supporting the shelves
either releasably interlocked with the cabinet side walls or
maintained separate therefrom.
It is the general purpose of the present invention to provide a
bracket which is adjustable between two positions. In the first,
the bracket not only supports the shelf, but also releasably
interlocks it with the side walls. In the second, it supports the
shelf only, with the result that the shelf may be removed easily
from the cabinet by sliding it outwardly. In both of these bracket
positions, the shelf is supported on substantially the same
horizontal plane.
It is a further object of the present invention to provide a
cabinet shelf bracket which is easily and inexpensively
manufactured in integral form by application of the techniques of
plastic molding, which is easily mounted on and demounted from the
cabinet shelf assembly, and which is adjustable easily and
accurately between its positions of use, i.e., between a first
position in which it supports and interlocks and a second position
in which it supports only.
Broadly considered, the presently described cabinet shelf bracket
comprises a side wall bearing plate having extending laterally
outwardly from its inner face a side wall pin dimensioned for
insertion in a side wall socket. A substantially horizontal shelf
bearing plate extends laterally outwardly from the outer face of
the side wall bearing plate in substantially axial alignment with
the side wall pin. A vertical shelf pin extends laterally outwardly
from the outer end of the shelf bearing plate. It is dimensioned
for insertion in a socket underneath an end margin of the
shelf.
The bracket is rotatable angularly through 180.degree. between two
positions. In one of these, the shelf pin extends upwardly and is
insertable in the shelf socket for releasably interlocking the
shelf to the side wall. In the other, the shelf pin extends
downwardly in disengaged position, permitting free separation of
the shelf from the cabinet side wall. In both positions, the shelf
is supported by the bracket in substantially the same horizontal
plane.
In the drawings:
FIG. 1 is a perspective view of the reversible cabinet shelf
bracket of my invention;
FIG. 2 is a foreshortened sectional view of the bracket in its use
position,
FIGS. 3 and 4 are fragmentary perspective views of a shelf assembly
including the herein described bracket, employed in its combination
shelf-supporting and shelf-locking positions; and
FIG. 5 is a fragmentary perspective view, similar to FIGS. 3 and 4,
but illustrating a shelf assembly incorporating the bracket in its
shelf-supporting position only.
As is illustrated in FIGS. 3, 4 and 5, the herein described bracket
is designed for use in cabinet assemblies including a pair of
spaced, vertical side walls 10 each having on its inner face at
least one pair of horizontally spaced, substantially coplanar
sockets 12. In the practical application of the invention, the side
wall sockets are arranged in two substantially parallel vertical
rows with the sockets placed in horizontally coplanar pairs. This
permits adjustment of the shelves within the cabinet at desired
elevations.
A horizontal shelf 14 is dimensioned for insertion between the side
walls in substantially contiguous relation thereto. It has on its
underneath end margins at least one, preferably a pair, of sockets
16. These have a horizontal spacing substantially equal to that of
side wall sockets 12.
The shelf sockets are substantially aligned with each other
transversely of the shelf, and with the side wall sockets
longitudinally of the shelf. This arranges the shelf and side wall
sockets in adjacent pairs. Each pair is designed to receive one of
the herein described brackets in shelf-supporting and
shelf-interlocking relation.
The construction of the brackets is illustrated in FIGS. 1 and
2.
Each bracket 20 has a side wall bearing plate 22 having an inner
face 24 and an outer face 26. The inner face of plate 22 is adapted
to bear against the inner face of side wall 10, overlying one of
side wall sockets 12.
A side wall pin 28 extends laterally outwardly from the inner face
24 of the side wall bearing plate. It is dimensioned for press fit
insertion in the side wall socket 12 which the bearing plate
overlies, thus frictionally mounting the bracket on the side
wall.
A substantially horizontal, shelf-bearing plate 30 extends
laterally outwardly from the outer face 26 of side wall bearing
plate 22. To maintain a constant shelf elevation in the two
positions of the bracket, the shelf bearing plate lies in
substantially axial alignment with side wall pin 28. As is
particularly evident in FIG. 1, the shelf bearing plate preferably
is broad at its base and tapered inwardly toward its outer
extremity to provide a broad bearing surface as required adequately
to support the shelf.
A shelf pin 32 extends laterally outwardly from the outer end of
the shelf bearing plate. It is dimensioned for insertion in a press
fit in one of shelf sockets 16, in pin and socket relation.
By comparison of FIGS. 4 and 5, it will be observed that the herein
described shelf bracket is adjustable in use angularly through
180.degree. between two positions. In the FIG. 4 position, at least
one of the shelf pins of each pair of shelf pins employed to
support one end of shelf 14 is disposed upwardly. In this position,
it is received in the adjacent shelf socket 16. This releasably
interlocks the shelf and cabinet side walls so that the former can
only be separated from the latter by lifting it upwardly.
However, in the FIG. 5 position of the bracket, shelf pin 32 is
arranged downwardly, out of engagement with the shelf socket. This
bracket position permits easy removal of the shelf from the
cabinet, simply by sliding it outwardly in its own plane.
It is to be observed further that the shelf lies in the same plane
in both positions of the bracket. Also, the construction of the
bracket and its manner of mounting adapt it well to use in knock
down, do-it-yourself cabinet assemblies.
