Abstract

A knock-down or collapsible bar for serving beverages or food or the like and which has a front wall and side wall structures for supporting a counter. The front wall is comprised of two separate sections, and these two sections are hinged together and are also hinged to the sidewalls whereby the walls can be folded together in accordian fashion and in a very compact and relatively narrow package. Each of the walls is comprised of side rails and cross rails which form a generally rectangular frame structure in which flexible fabric-like panels are removably inserted. The counter is readily attached to and detached from the upper edge of the walls and an interior shelf is replacable and easily set within the walls so as to rigidify them and hold them in assembled relationship with the counter. Straps are detachably connected between the interior shelf and the sidewalls so as to further rigidify the structure when in assembled position. The entire structure can be readily disassembled and compactly folded in such a manner that the interior shelf nests in the underside of the counter and the walls when folded in accordian fashion form a dimensioned package that is generally the same as the container; the entire assembly can then be readily and compactly packaged in a box for storage or transport.

Nilles l 5 7 ABSTCT A knock-down or collapsible bar for serving beverages or food or the like and which has a front wall and side wall structures for supporting a counter. The front wall is comprised of two separate sections, and these two sections are hinged together and are also hinged to the sidewalls whereby the walls can be folded together in accordian fashion and in a very compact and relatively narrow package. Each of the walls is comprised of side rails and cross rails which form a generally rectangular frame structure in which flexible fabric-like panels are removably inserted. The counter is readily attached to and detached from the upperedge of the walls and an interior shelf is replacable and easily set within the walls so as to rigidify them and hold them in assembled relationship with the counter. Straps are detachably connected between the interior shelf and the sidewalls so as to further rigidify the structure when in assembled position. The entire structure can be readily disassembled and compactly folded in such a manner that the interior shelf nests in the underside of the counter and the walls when folded in accordian fashion form a dimensioned package that is generally the same as the container; the entire assembly can then be readily and compactly packaged in a box for storage or transport.

6 Claims, 14 Drawing Figures COLLAPSIBLE BAR BACKGROUND OF THE INVENTION The present invention pertains to collapsible cabinet structures and particularly those of the type having a serving counter across the top and are generally portable in nature.

An example of a prior art type of portable bar over which the present invention is an improvement is shown in the U.S. Pat. No. 3,033,632 which issued May 8, 1962 and entitled Collapsible Bar to Major Felten. In that device, the front wall was of such a dimension that it defined not only the overall height of the bar, but also the overall width of the bar and that particular bar when completely collapsed had a dimension generally that of the relatively large front wall, and generally that bar could not be collapsed into as compact an assembly as contemplated by the presentinvention.

SUMMARY OF THE INVENTION The present invention provides a collapsible bar having ground engaging and counter supporting walls comprising two sidewalls and a front wall which is made of two sections, those sections and the sidewalls each being generally of the same width whereby they can be folded in accordian fashion in a particularly compact manner. Each of the sections and sidewalls is comprised of side frame and cross frame members which form a rigid end in which are removably mounted flexible panels for advertising or the like. The panels can be removed for cleaning or replacement of one type or another. The counter of the portable bar has'a guide or rigidifying rail along one edge thereof and against which the upper edge of the front wall bears when in assembled relation. The counter also has spring type catches for quickly and releasably engaging the side walls to further rigidify the structure in assembled relationship. An interior shelf is provided for being detachably located within and between the vertical walls when in the assembled position and which acts to hold the sections of the front wall and the sidewalls rigidly in place against the undersurface of the counter top. This interior shelf, when the bar is disassembled, and folded together, is nested within the undersurface of the counter top in a compact manner. The assembled interior shelf and counter top are approximately the same overall dimension as the full collapsed walls and thereby form a compact package.

A more limited aspect of the invention relates to the quickly removably fabric panels for each of the vertical walls.

These and other objects and advantages of the present invention will appear hereinafter as this disclosure progresses, reference being had to the accompanying drawings.

DESCRIPTION OF A PREFERRED EMBODIMENT the line The wall structure for the bar of the present invention is comprised of a left sidewall l, a right sidewall 2, and a front sidewall 3. The front sidewall 3 in turn is comprised of a front wall 4 and front wall 5, which are similar in construction, shape and size, to the-sidewalls. As shown in FIG. 5, when the walls are folded together in accordian fashion, it will be noted that the

walls

1 and 2 are of the same'width as the

front walls

4 and 5. The

front walls

4 and 5 are hinged together along their adjacent edge by hinges 6 which permit the front walls to fold with their front surfaces together while the

sidewalls

1 and 2 are hinged by pairs of

hinges

7 and 8, respectively, to

sections

4 and 5, respectively, so that the inner surface of

walls

1 and 2 abut against the inner surface of

walls

4 and 5, respectively when in the assembled position shown in FIG. 5. As mentioned above, each of the walls are similar in construction, size and shape, and have two parallel and vertically arranged

side rails

10 and 11, which are rigidly held in spaced apart relationship by the

cross rails

12 and 13. The

cross rails

12 and 13 are rigidly joined to

members

10 and 11 in any manner, such as by dowl joints, glue, or the like. It is believed a description of one of these walls will be sufficient inasmuch as all of the walls are similar as above noted. In any event, the vertical wall is formed as a generally rectangular frame member in which is detachably mounted a flexible fabric 15 having a loop sewn in each of its upper and lower ends. A cross bar 17 is inserted in each of the loops and is of a length that fits snugly between the

vertical rails

10 and 11. A hole 18 is drilled through the cross bars and a metal rod 19 is inserted through these holes and also through aligned holes 20 in the vertical rails 10 and Ill. The rods can be easily inserted through the aligned holes to hold the panel in assembled relationship in the wall and can be pushed out of the holes and withdrawn therefrom in order to remove the panels for cleaning, replacement, or repair. The panels may contain advertising or other decorative displays thereon.

The horizontal counter 25 is of such a size that it extends slightly over the walls when in the assembled position and has a front guide rail 26 rigidly secured along the front edge thereof. As shown in FIG. 8, when the bar is assembled, the

front walls

4 and 5 abut against the rail 26 While the upper edge of the sidewalls l and 2 are snugly engaged by the

steel spring members

30 and 31, respectively. The spring members are formed as opposed spring clips which abut against the sides of the walls and hold them firlmy in position. The walls are further rigidly held in relationto the counter by the interior shelf 35 shown clearly in FIGS. 4 and 9. This interior shelf is formed of a trapezoidal shape which complements the interior shape of the walls when assembled and as clearly shown in FIG. 4. The sidewalls have upwardly facing

hooks

37, 38, 39 and 40 (FIG. 3) which receive the correspondingly positioned

hooks

47, 48, 49 and S FIG. 9) of the interior shelf. The inv terior shelf is easily assembled in the wall structure by simply inserting it into the wall structure slightly above the hooks of the wall structure and then lowering it into place where the hooks of the interior shelf rest on the hooks of the wall structure. This acts to rigidly hold the walls in their proper position relative to one another and also relative to the counter and the guide rail 26 thereof.

As shown in FIG, 2, the assembled structure is further rigidified by the

strap members

60, 61 which have female snap members 62 at each of their ends and which snugly snap and thereby engage the

male snap members

64 and 65 located, respectively, on the rear edge of the interior shelf and also at the lower rear edge of the sidewalls l and 2.

When the bar is disassembled, it will be noted as shown in FIG. II), that the interior shelf nests against the underside of the counter and more specifically between the guide rail 26 and the other guide rail 27 arranged in parallelism and along the rear edge of the undersurface of the counter.

Straps

60 and 61 are also used to securely hold the interior shelf to the underside of the counter and male snap members 66 are provided on the underside of

rails

26 and 27 forthis purpose.

The overall width of the folded walls as shown in FIG. is generally the same as the width of the counter and therefore the entire bar forms a relatively small, compact package for storing and shipping containers or the like.
