DISPLAY TRAY AND BRACKET ASSEMBLY FIELD OF THE INVENTION This invention relates to a shelf bracket for supporting a display tray on a pair of upright and elongated posts and, more particularly, relates to a shelf bracket which relies on the pressure of the display tray positioned between the posts for main taining the engagement of the self bracket with the upright posts.

BACKGROUND OF THE INVENTION Various types of supporting devices for display trays are known and have proven to be successful commercially. However, display trays which are positioned between a pair of horizontally spaced, upstanding and elongated posts have not been entirely satisfactory due either to the use of complicated mechanisms for securing the same to the posts or, where simplicity is attained, due to limited reliability or flexibility. Particularly, where the devices are acceptably reliable and capable of commercially necessary adjustment, they are often space consuming which results in a decrease in the size of the display tray which can be mounted between the posts.

One type of display tray supporting device utilizes a post having a plurality of vertically spaced, rectangular-shaped openings in one wall thereof which receive the hooks on a support member. The openings in the posts must be large enough to receive the hooks on the support member. When stability of the known support members is required, then two rows of vertically spaced openings are provided in the posts which receive at least a pair of horizontally spaced hooks on a support member. This construction thereby minimizes the tendency of the support member to twist relative to the posts. In many instances, particularly where an attempt is made to provide the many openings needed to maximize the number of vertical positions to which the display tray can be adjusted, one wall of the post has so many openings therein that they substantially weaken the post structure.

Therefore, the objects of this invention include:

I. To provide a shelf bracket for a display tray which is positionable between a pair of horizontally spaced, upstanding and elongated posts wherein the assembled thickness of the shelf bracket is minimized in order to maximize the size of the display tray.

2. To provide a bracket assembly which is of a two-piece construction and wherein the connection between the two pieces is simple and requires no maintenance.

3. To provide a bracket assembly, as aforesaid, which relies upon pressure of the display tray positioned between the pair of posts to maintain the bracket assembly in engagement with the posts.

4. To provide a racket assembly, as aforesaid, which is inexpensive to manufacture, rugged and very simple to use.

Other objects and purposes of this invention will be apparent to persons acquainted with apparatus of this general type upon reading the following specification and inspecting the accompanying drawing, in which:

FIG. I is a perspective view of an assembled display tray arrangement;

FIG. 2 is an enlarged end view of the display tray and the bracket assembly;

FIG. 3 is a sectional view taken along the line III-III of FIG.

FIG. 4 is an exploded perspective view of the bracket assembly.

Certain terminology will be used in the following description for convenience in reference only and will not be limiting. The words .up," down, right and left will designate directions in the drawing to which reference is made. The words in and out will refer to directions toward and away from, respectively, the geometric center of the device and designated parts thereof. Said terminology will include the words above specifically mentioned, derivatives thereof and words of similar import.

SUMMARY OF THE INVENTION The objects and purposes of the invention are met by providing a pair of two-piece bracket assemblies which are positionable between the ends of a display tray and a pair of horizontally spaced, upstanding and elongated posts so that one of the bracket members will be positively held adjacent the posts by the display tray and consequently unable to be separated from the posts until after the pieces of the bracket assembly secured to the end of the display tray are separated from the members engaging the posts.

DETAILED DESCRIPTION The merchandise display tray 10 illustrated in FIG. 1 comprises a pair of leg structures 11 and 12 separated by a spacing bar I3. A pair of L-shaped brackets 14 and I6 are secured to the leg structures 11 and 12, respectively, as by welding the spacing bar I3 is secured as desired to the horizontal legs of the L-

shaped brackets

14 and 16, here by a plurality of screws 17. A pair of posts 18 and I9 are secured to the vertical legs of the L-shaped brackets I4 and 16, as by screws 21, and have a plurality of vertically spaced, circular openings 20 therein.

The display rack I0 is further comprised of a shelf or tray 22. In this particular embodiment, the tray is comprised of a wire mesh construction having two

sidewalls

23 and 24 and two

end walls

25 and 26 and a bottom wall 27. The length of the tray 22 is slightly less than the spacing between the posts I8 and I9 to define a pair of clearances 30 therebetween, one of which is shown in FIG. 3.

The bracket assembly 28 is comprised of two parts, namely a first member 29 which is securable to the posts 18 and I9 and a second member 31 fixedly secured to the

end walls

25 and 26 of the tray 22. The first member 29 is comprised of a flat base portion 32 having a pair of openings 33 (FIG. 3) therethrough, the spacing between said openings 33 being identical to the vertical spacing between the openings 20 in the

posts

18 and 19. A pair of pins 34 having enlarged heads 36 are received through the openings 33 so that the pin portions 34 project outwardly therefrom. The diameter of the enlarged heads 36 is greater than the diameter of the openings 33 and are secured to the base portion 32, as by welding (FIG. 3).

A pair of

tabs

37 and 38 are formed on the upper end of the base portion 32 and project outwardly in parallelism with the pins 34. In this particular embodiment, the

tabs

37 and 38 are horizontally spaced a distance only enough greater than the thickness of the

posts

18 and 19 to enable said tabs to embrace said posts easily yet snugly. A pair of

tabs

39 and 41 are formed at the lower end of the base portion 32 and project outwardly in parallelism with the pins 34 and are spaced a distance equal to the thickness of the

posts

13 and 13.

The base portion 32 also supports a pair of laterally extending L-shaped flanges 42 and 43. In this particular embodiment, the legs 44 and 46 of the flanges 42 and 43 are parallel with the base portion 32 and are connected thereto by the legs 47 and 43 (FIG. 3). The flange legs 44 and 46 are offset from the base portion 32 a distance approximately the thickness of the heads 36, whereby said heads 36 are recessed in the trough 49 formed by the base portion 32 and the legs 47 and 43.

The outer edges 51 and 52 (FIG. 2) of the flanges 42 and 43 are inclined 4 to 10 from the vertical to define locking surfaces. In this particular embodiment, the

edges

51 and 52 are inclined at 5".

The second member 3ll is secured to the

end walls

25 and 26 as by welding. The second member 31 is comprised of a flat sheet metal base 53 having

end portions

54 and 56 which are bent at back upon the base portion 53 to define a pair of elongated recesses 57 and 53. The

end portions

54 and 56 are formed in such a manner that the elongated recesses 57 and 58 are inclined 4 to 10 to the vertical. Furthermore, the width of the elongated recesses 57 and 53 is slightly greater than the thickness of the flanges 42 and 43 and the horizontal spacing between the bottoms of the recesses 57 and 58 is preferably equal to the horizontal distance between the

surfaces

51 and 52 so that when the flanges 42 and 43 are inserted into the recesses 57 and 58, the second member 31 will become supported on the flanges 42 and 43.

OPERATION The operation of the device embodying the invention will be described in detail hereinbelow for a better understanding of the invention.

Since the length of the display tray 22 is slightly less than the horizontal spacing between the

posts

18 and 19, there is just enough room in the clearances 30 defined therebetween for the reception of the first and

second members

29 and 31, respectively, of the two bracket assemblies 28 at each end of the tray. The pins 34 of the first members 29 are inserted into the openings 20 in the

posts

13 and 19. The

tabs

37, 38 and 39, engage the sidewalls of the posts to assist the pins 34 in preventing a twisting of the first member 29 relative to the

posts

18 and 19.

The second members 31 which are secured to the end walls and 26 of the tray 22 are telescoped over the flanges 4-2 and 43 of the first member 29 so that the tray 22 will become supported on the first members 29. The inner side surfaces of the elongated recesses 57 and 58 will engage the

edges

51 and 52 on the first member 29 to define an interlocking engagement between the first and second members. Since the space between the horizontally spaced

posts

18 and 19 is virtually taken up by the length of the tray 22 and the assembled thicknesses of a pair of bracket assemblies 28, the first members 2% are positively held against the posts 13 and 59 so that the pins 34 thereof are able to retract from the holes 20.

When adjustment in the height of the tray 22 relative to the posts is desired, the second members 31 secured to the tray 22 must be disconnected from the first members 29. This is accomplished by lifting the tray 22 upwardly. The inner surfaces of the recesses 57 and 58 will become disengaged from the

edges

51 and 52. Once the tray 22 is moved out from between the

posts

18 and 19, the first members 29 can then be pulled outwardly away from the posts and the pins 34 are withdrawn from the openings 20. The first members 29 can then be selectively repositioned vertically on the

posts

18 and 19. The process of assembling the shelf to the

posts

18 and 19 is the reverse of the disassembling process.
