T. E. KENNEDY ANGULARLY ADJUSTABLE SHELF BRACKET April 26, 1966 Filed Dec. 50, 1965 United States Patent 3,248,079 ANGULARLY ADJUSTABLE SHELF BRACKET Thomas E. Kennedy, Niles, Mich, assignor to Clark Equipment Company, a corporation of Michigan Filed Dec. 30, 1963, Ser. No. 334,462 4 Claims. (Cl. 248-242) The present invention relates to an adjustable shelf bracket, and more particularly to a shelf bracket which is both vertically and angularly adjustable on a slotted standard or upright.

In shelf brackets of the type mounted for angular adjustment on slotted uprights, it. is desirable that the brackets be light in weight in order to facilitate the handling thereof and allow a greater proportion of the load supported by the uprights to be represented by the merchandise, yet that they be amply strong to support such greater weight of merchandise. It is furthermore important that the angular adjustment structure be simple so that the adjustments may be made quickly and easily, that it provide a secure engagementwith the upright in all positions so as to avoid possible dislodgement, and that it occupy only a small space so that the uprights may be of relatively slight depth. A good bearing surface of the bracket on the upright is also advantageous, to provide for firm support of the bracket and of the shelf mounted thereon.

The present invention has for its objects the provision of a shelf-supporting bracket which is angularly adjustable to a number of different positions, as well as being vertically adjustable, which is simple and inexpensive to manufacture, which is securely engaged with a supporting upright in all positions, which has good bearing contact with the upright in all positions,' and which has minimal projection of the securing and adjusting means rearwardly of the brackets so as to require only shallow-depth upright members.

Other and further objects, advantages and features of the invention will be apparent to those skilled in the art from the following detailed description, taken in conjunction with the accompanying drawings, in which:

FIGURE 1 is a fragmentary vertical sectional view through a conventional slotted upright, showing the bracket of the invention in side elevation, engaged with the .upright in a first angularly adjusted position thereof;

FIGURE 2 is a view similar to FIG. 1, but showing the bracket in a second-adjusted angular position;

FIGURE 3 is a view similar to FIGS. 1 and 2, but

showing the bracket in a third angularly adjusted position; and

FIGURE 4 is a somewhat diagrammatic view on a small scale showing the supporting structure for the bracket, and illustrating three angular positions of the bracket corresponding to those of FIGS. 1, 2 and 3, shown respectively in full, dotted, and dot-dash lines.

Referring to the drawings, the adjustable bracket of the present invention is designated generally as 10, and is associated with a standard or upright U which extends vertically upward from a supporting base B and may be of channel or hat section, or tubular, for example, to provide a web formed with a series of vertically spaced apertures or slots S therein, as is well known in the art. The bracket may be formed of metal sheet or plate of suitable strength and thickness, and comprises a generally planar body portion 11 adapted for disposition in a vertical plane and having a straight shelf-carrying edge provided with a flange 12. The bracket body 11 engages at what may be termed its rear end edge with the upright U, and may extend forwardly for any desired length or distance from the rear edge. In the illustrated embodiment of the bracket, provision is made for disposing it in three different angular positions inclined downwardly and forwardly relative to the upright, although it will become apparent that the number of angular positions may be varied.

The rear end edge 13 of the bracket body 11 is straight, as indicated in the drawings, and includes a lower straight portion 14 in the same plane. The rear edge 13 in-' cluding the lower rear portion 14 engages against the outer face of the slotted web of the upright U .in the first angularly adjusted position of the bracket, that is the position shown in FIG. 1 and in solid lines in FIG.

4. In the present instance, the rear edge 13 is shown as extending at an angle of somewhat more than to the upper straight edge of the bracket body 11, to allow for downward deflection of the bracket under the load of supported merchandise displayed on the shelf carried by the bracket as well as to tend to prevent falling of merchandise off the shelves. Obviously, the angle between the upper edge and rear edge of the body of the bracket 10, may be 90, or more or less than 90, as may be desired. The rear portion of the bracket 10 may be provided with a pair of bearing lugs 15 struck from the rear portion of the body and bent in opposite directions laterally of the bracket body 11, as shown in FIGS. 1 to 3 inclusive. The lugs 15 are preferably formed adjacent the central portion of the rear edge of the body 11, and serve as additional bearing means in the first angularly adjusted position of the bracket, engaging against the upright U and assisting in distribution of the load. Extending integrally from the rear edge 13 of the bracket body 11 are three rearward projections spaced along the edge 13, comprising an upper tongue 16, a lower tongue 17 and a tang 18. The tang 18 is disposed just above the lower portion 14 of the-rear bracket edge,

and the lower tongue 17 is disposed between the tang 18 and the upper tongue 16, which is located adjacent the upper edge of the body 11. The tongues and tang are so located relative to each other along the rear edge of the body'll as to be simultaneously engageable in three of the slots S of the upright U, the relative positions of the tongues and tang in the present instance being such that the tongues 16 and 17 engage in vertically adjacent slots S, while the tang 18 engages in the second slot below that which receives the lower tongue 17, in the first or FIG. 1 position of the bracket. Each of the tongues 16 and 17 is provided with a downwardly opening notch 19 in its lower sufrace of a width at least equal to the thickness of the material of the slotted upright web, the rear edge of each notch 19 being substantially parallel to the plane of the rear edge 13 of the bracket body, and spaced from such plane by a distance at least equal to the thickness of the web material, but not considerably greater than such thickness. As best shown in FIG. 1, the notches 19 are dovetailed or undercut so as to allow for a coating of paint or the like on the upright U, allowing the bracket to seat properly on the upright U. In this position, it will be evident from FIG.

1 that the rear edge 13 of the body 11 of the bracket it including the lower portion 14, and also including the rear edges of the lugs 15, engages in good bearing relation against the outer face of the slotted web of the upright totransmit the load represented by the merchandise on the shelf carried by the bracket 10. As will also be evident from FIG. 1, the lower surface of the tang 18, which in this instance is shown as rectangular,

3 is so spaced from the bottoms of the notches 19 as to seat on the lower edge of the tang-receiving slot edge when the bottom edges of the notches seat 'on the lower edges of the slots receiving the tongues 16 and 17, respectively. The tongues 16 and 17 and the tang 18 are of such vertical dimensions as to move readily through the respective slots S of the upright U. The bracket may thus be readily engaged with and disengaged from the upright.

The bracket is engaged on the upright in the position of FIG. 1 by disposing the rear end thereof adjacent the slotted upright web with the tongues 16 and 17 and tang 18 opposite the respective slots S which are to receive them, moving the bracket rearwardly to engage the tongues and tang in the slots, and then moving the bracket'downwardly to dispose the notches 19 inembracing relation to the lower edges of the slots. The bottom edges of the notches are engaged on the lower slot edges, and the lower surface of the tang 18 similarly is seated on the lower edge of its associated slot with the rear edges of the notches 19 bearing on the rear face of the web.

The rear bracket edge 13, including the lower portion 14 thereof and the lugs 15, bears on the upright as already pointed out. tion, it is only necessary to' move it upwardly on the upright so as to disengage the notches 19 from the upright and then to move the bracket forwardly to draw the tongues 16 and 17 and tang 18 out of the slots S.

The upper tongue 16 is considerably longer than the lower tongue 17, and has in its lower edge a second downwardly opening notch 20, the rear edge of which is disposed at an angle to the rear edge 13 of the bracket corresponding to the downward inclination of the bracket desired in the second or intermediate angular position,

shown in FIG. 2. The bottom edge of the notch is substantially perpendicular to the rear edge, and the width of the notch is preferably slightly greater than the thickness of the slotted web of the upright, as will be evident from FIG. -2. Extending forwardly from the lower end of the lower rear edge portion 14 of the bracket is a seating edge or surface 21, disposed at an angle to the portion 14 as hereinafter described, and defining a ledge or shoulder. The rear edge of the notch 20 in the upper tongue 16 is disposed in a plane extending at an angle relative to the rear edge 13 of the bracketbody 11, the angle corresponding to the difference in inclination of the bracket desired between the first and second positions. In the second or intermediate position shown inFIG. 2, the point or juncture 22 between the edges or surfaces'14 and 21 engages against the slotted web of the upright, being spaced forwardly of the plane of the rear edge ofnotch 20 by a distance corresponding to the web thickness. The tang 18 engages on the lower edge of the slot in which it is received, and the notch 20 receives the lower edge of the slot through which the tongue 16 projects, the rear edge of the notch 20 bearing on the inner face of the web. The tongue 17 is formed of such shape and size as to have a slight clearance relative to the web in this position of i the bracket, this clearance being shown somewhat exag gerated in FIG. 2. The bracket is disposed in and removed from the second angular position in substantially the same manner as described in connection with the position of FIG. 1, except that the tongue 17 does not engage in a slot of the upright web.

The bracket is also disposable in a third angular position, inclined downwardly and forwardly at a greater angle than the second position, as shown in FIG. 3. For this purpose, the upper tongue 16 is provided with an upwardly directed notch 23 in its upper edge having a rear I edge 24 in a plane extending at an angle to the rear end edge 13 of therbody 11 corresponding to the downward inclination of the bracket desired relative to its position as shown in FIG. 1. The seating surfaceor edge 21 extends at substantially right angles to the plane of the notch rear edge 24, and at an acute angle relative to the To disengage the bracket from this posi-,

lower portion 14 of the body rear edge 13. A bearing surface 25 is formed at the rear end of the bracket, ex.-

tending downwardly fromthe forward end of the seata ing edge or surface 21 for any appropriate distance. The bearing surfacev 25 extends ina plane parallel to the plane of the rear edge 24 of the notch 23, and spaced;

forwardly therefrom by a distance corresponding to the thickness of the slotted web of the upright.

To dispose the bracket in the most sharply angled or third position as shown in FIG. 3, the bracket is disposed with the tongue 16 and tang 18 in opposition to two of the slots S in the upright web, and moved rearwardly to extend the upper tongue 16 through one of the slots and 1 the tang 18 through a lower slot, until the upwardly opening notch 23 in the upper edge of tongue 16 is below the upper edge of the tongue-receiving slot, whereupon the bracket is moved upwardly so that the rear edge 24 of the notch extends above the level of the upper edge of the tongue-receiving slot. The lower portion of the rear end of the bracket is then swung rearwardly so that both the tang 18 and the point 22 between the surfaces 14 and 21 extend through the tang-receiving slot and the bearing surface 25 engages the outer face of the web. The seat ing surface 21 engages on the lower edge of the tang-.

receiving slot to maintain the rear edge 24 of the notch 23 in tongue 16 projecting upwardly beyond the upper edge of the tongue-receiving slot, and in engagement with the rear or inner face of the upright web. As willbe apparent from a comparison of FIG. 3 with FIGS. 1

and 2, the bracket is elevated relative to its positionin FIGS. 1 and 2 by reason of the provision of the seating surface or edge 21 spaced below the tang 18,and its ongagement on the lower edge of the slot. The distance between the seating surface 21 and the bottom of the notch 23 is slightly less than the distance between the lower edge of the tang-receiving slot S and the upper edge of the tongue-receiving slot, as shown in FIG. 3, in order to allow for a slight clearance in applying and removing 1 the bracket to and from the upright U in the third position. Removal of. the bracket is accomplished by sub-.

stantialreversal of the movements employed in applying 1 the bracket.

By providing the notch 23. in the upper edge of the tongue 16, and providing a ledge or shoulder with the seating surface 21 to raise the tongue relative to the upright, the third position is provided for withoutrequiring an unduly long tongue, and without undue weakening of the tongue.

It will be apparent that the particular angles at which the bracket is disposed relative tothe upright may be varied from the particular angles shown, merely by changes in the relative angularity of the appropriate surfaces or edges of the bracket parts. Similarly, the bracket may be adapted for dispositionin more than three angular, positions by providing additional adjusting means in ac-. cordance with the principle disclosed.

The bracket as disclosed herein is simple to manufacture and use, is readily adjustable to its several angular positions, is securely inter-engaged with the upright in all 1 its angular positions, requires minimum space for accommodation of the tongues, and has good bearing engage-.

ment on the upright in all positions.

It will be understood that the single embodiment of the invention illustrated herein in exemplary of the inventive concept and that the invention is not limited to such embodiment, since modifications and variations thereof,

may be made without departing from the spirit and scope of the invention as set forth in the appended claims.
