B f Description of the Drawings P~eference is made to the accompanying drawings in which is shown an illustrative embodiment of the invention from ~; 25 which its novel features and advantages will be apparent.
In the drawings:
FIG.l is a right side elevational view of one form of bracket assembly illustrative of an embodiment - _ 5 _ :, ~æ3~
of the invention, shown in combination with an upri.ght support and wire shelf, the latter elements shown in section for clarity;
FIG.2 is a top plan view of the elements shown in FIG. l;
FIG.3 is an enlarged right side elevational view of the bracket assembly;
FIG.4 is an enlarged left side elevational view of the bracket assembly;
FIG.5 is a sectional view of an illustrative lock means, shown in one position; and FIG.6 is a sectional view, similar to FIG. 5, but showing the lock means in an alternative position.
Description of the Preferred Embodiment Referring to the drawings, it will be seen that thP
illustrative bracket assembly 2 includes a bracket member 4, a first sIide member 6 mounted on the bracket member, and a second slide member 8 mounted on the bracket member.
The bracket member 4 comprises a rigid, elongated, sub-stantially planar member, pre~erably of metal.
The flrst slide member 6 (FIG.3) comprises a rigid, elonga~ed member, preferably of metal, having a planar portion 10 (FIG.2) disposed adjacent a planar surface 12 of ~he bracket member 4 and slidable thereon. The first ;~ ~ slide member 6 is provided with an edge 14 disposed co-~; ~ incidentally with a bracket member lengthwlse edge 16 (FIGS.2 and 3). A first hook portion 18 extends out-wardly from the first slide member edge 14 and forms a first notch 20. The first hook portion 18 is provide~
with a first leg portion 22 adapted to overlie a shelf first portion.
The second slide member 8 (FI&.3) comprises a rigid, elongated member, preferably of metal, having a planar portion 24 (FIG.2) disposed adjacent the planar surface 12 of the bracket member 4 and slidable thereon. The second slide member 8 is provided with an edge 26 disposed coin-cidentally with the bracke-~ member edge 16 (FIGS.2 and 3).
A second hook portion 28 extends outwardly from the second slide member edge 26 and forms a second notch 30. The second hook portion 28 is provided with a second leg portion 32 adapted to overlie a shelf second portion. The second hook portion 28 is substantially aligned wit`h and opposed to the first hook portion 18. The first and second notches 20, 30 are thus in alignment with each other and opposed.
The bracket member 4 is provided with opening means, preferably in the form of an elongated slot 34, having ` enlarged portions 36 disposed along the length thereo.
Six such portions are shown in FIGS. 3 and 4, but any desired number of such enlarged portions may be incorporated in the slot 34. A first pin 38 (FIG.3) is fixed to the ~irst slide member 6, a shank portion 40 of the first ~: - 7 -"
~2~80~
pin 38 extending through the slot 34. The first pin 38 is provided with a head 42 (FIG.4) larger than the width of the slot 34, to retain in a slidable mode the slide member 6 upon the bracket member surface 12.
A second pin 44 is mounted for reciprocal movement in the assembly and includes a first enlarged head 46, a first enlarged shank portion 48, a second shank portion 50, and a second enlarged head 52. The second pin second shank portion 50 is disposed in a hole 54 in the first slide member 6. The second pln first enlarged shank portion 48 is larger in diameter than the width of the slot 34, but slightly smaller than the enlarged portions 36 of the slot 34. The second shank portion 50 of the pin 44 extends through the hole 54 and is joine~ to the second enlarged head 52. A coil spring 56 is disposed between the head 52 and the first slide member 6 and biases an edge 58 of the shank portion 48 firmly against the bracket member 4 to hold the members 4, 6 together (FIG.5).
: If the slide member 6 is moved to the right, as viewed in FIGS. 1 and 3, to a point at which the second pin first enlarged shank portion 48 is in alignment with one of the slot enlarged portions 36, the shank portion 48 will be caused by the coil spring 56 to snap into the enlarged slot portion 36, to securely lock the bracket mem-~ 25 ber 4 and the slide member 6 together (FIG.6).
: The first slide member 6 preferably is provided with : a first grip portion 6~ extending outwardly from the : - 8 -bracket member at an angle to the plane of the slide member planar portion 10.
Similarly, a third pin 62 (FIG.3) is fixed to the.
second slide member 8, a shank portion 64 of the third pin 62 extending through the slot 34. The third pin 62 is provided with a head 66 (FIG.4) :Larger than the width of the slot 34, to retain in a slidable mode the second slide member 8 upon the bracket member surface 12.
A fourth pin 68 is mounted for reciprocal movement in the assembly and includes a first enlarJed head 70, a first enlarged shank portion 72, a second shank portion 74, and a second enlarged head 76. The ourth pi.n second shank portion 74 is disposed in a hole 78 in the second slide member 8. The fourth pin first enlarged shank portion 72 is larger in diameter than the width of the :~ slot 34, but slightly smaller than the enlarged portion 36 of the slot 34. The second shank portion 74 of the pin 68 extends through the hole 78 and is joined to the second enlarged head 76. A coil spring 80 is disposed between the head 76 and the second slide member 8 and biases the pin 68 in the same manner as described above relative to the second pin 44.
The bracket member 4 is preferably provided with tab ~ portions 81 integral with an end of the bracket member : 25 for engaging holes 83 in a support member 85 and thereby connecting the bracket member to the support member (FIG.l).
_ g _ ~æ~
The illustrative invention, as above described, is ideally suited for use in combination with shelves of the rigid wire type, with which the assembly is illustrated in FIGS. l and 2. As may be seen, the first notch 20 is adap-ted to receive a shelf first portion, such as a wire 82, and the second notch 30 is adapted to receive a shelf second portion, such as a wire 84. Upon manual depression of the heads 52, 76, the slide members 6, 8 are slidably moveable on the bracket member 4 to selectively determine the spacing between the fi.rst and second notches 20, 30. Upon releasing the heads 52, 76, the slide members are held against the bracket member by the force of the springs 56, 80, in a selected position, such that the first and second notches retain the shelf first and second portions, or wires 82, 84.
The pressure of the springs 56, 80 is su'ficient to permit usage of ~he assembly for a variety of wire spacings.
However, it is intended that the assembly be provided for use with shelving having known wire spacing. It is prefer-able that the spacing of two wires of the shelving coincide with the spacing of the first and second notches 20, 30 when the slide members 6, 8 are positioned on the bracket member such that the second and fourth pin enlarged shank portions 48, 72 are disposed, respectively, in one of the ; slot enlarged portions 36, thereby positively locking the members 4, 6 and 4, 8 together with the wires 82, 84 cap-tured in the notches 20, 30.
It will be apparent that in the locked ~sition, the ~23~
shelf first wire 82, disposed in the first notch 20 is blocked by the first hook portion 18, including the leg portion 22, from moving in any but a first direction, ' away from the support member 85, and that the shelf second wire 84, disposed in the second notch 30, is blocked by the second hook portion 28, including the leg portion 32, from movement in any but a second direction, toward the support member 85. Thus, inad-vertent dislodging of the shelf from the assembly is : 10 positively prevented.
Lf it is desired to change to a shelf having a different wire spacing, an operator need only depress the locking pi.n heads 52,..76 against the bias of the springs 56, 80, slide one or both of the slide members 6, 8 to a : 15 releasing position and remove the shelf. Wire portions of a new shelf can then be inserted between the notches 20, 30, the slide member 6 and/or slide member 8 moved to a posi~ion in which holding pressure is exerted on the wires disposed in the first and second notches, and locked . in place by releasing the locking pin heads 52, 76; or, preferably, one or both of the slide members mo~ed to a position in which the second and fourth pin shanks 4~; 72 enter a slot enlarged portion 36, and locked in place by releasin~ the locking pin heads 52 and/or 76.
It is to be understood that the present invention is by no means limited to the particular construction herein ; `"' disclosed and/or shown in the drawings, but also comprises any modifications or eyuivalents within the scope of the disclosure.
Having thus described my invention what I claim as new and desire to secure by Letters Patent of Canada is:

It is to be understood that the present invention is by no means limited to the particular construction herein ; `"' disclosed and/or shown in the drawings, but also comprises any modifications or eyuivalents within the scope of the disclosure.
Having thus described my invention what I claim as new and desire to secure by Letters Patent of Canada is:
