COLLAPSIBLE BAR
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.

Description
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
present invention.
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 wall structure for the bar of the present invention is
comprised of a left sidewall 1, 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 11. 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 1 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
relation to 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 50 (FIG. 9) of the interior shelf.
The interior 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 1 and 2.
When the bar is disassembled, it will be noted as shown in FIG. 10,
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 for this purpose.
The overall width of the folded walls as shown in FIG. 5 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.
