DISPLAY APPARATUS
Abstract
A display apparatus for stacking goods, such as cartons,
beverage containers, etc., includes a vertically extending frame
that is defined by two vertical side structures having a plurality
of generally horizontal support members. The two side structures
are interconnected by bracing means, and a plurality of shelves
extend between the two vertical side structures to accomodate
stacked goods. Each shelf is generally rectangular in plan form,
with the corners thereof being cut off so that the edge portions of
the shelf may be folded. Two edge portions are adapted to be
mounted on the horizontal support means, with each edge portion
being folded about three generally parallel lines so as to form a
U-shaped clip portion substantially corresponding to the
cross-section of the associated horizontal support members. The
clip portions of the shelf are snapped into place onto the
horizontal support members. The other two opposed side edge
portions are folded about two generally parallel lines so as to
form reinforcing beam members to provide additional rigidity to the
span of the shelf structure, and to provide a surface for pricing
or labeling. Assembly and disassembly of the display apparatus may
be readily accomplished in a very short period of time, since there
is no requirement for bolting each shelf to the frame
structure.

Description
The present invention relates to display apparatus and, more
particularly, to a quickly assembled and disassembled display shelf
apparatus which is especially useful in retail establishments, such
as supermarkets, drug stores and hardware stores, wherein there is
a constant requirement for temporary additional display
shelving.
In order to effectively merchandise new products, and to provide
increased shelf capacity for accomodating new products, there is a
constant need in retail establishments for additional shelf space
for displaying goods. The additional shelf space is normally
accomodated at the end of aisles, and hence there is a requirement
that the shopper must be able to remove products from the
additional shelving both from the front of the display shelf and
also from the sides. Hence the products mounted on the shelves must
be visible from at least three sides, and preferably from all
sides, and the display apparatus must be strong and sturdy, yet be
light enough so as to be easily manually assembled and disassembled
by a clerk with a minimum of tools. Furthermore, considering that
many times the auxiliary display apparatus is only required for a
day or two, the assembly and disassembly of the apparatus must be
accomplished very rapidly. Heretofore, auxiliary display apparatus
has normally been of the type wherein the frame structure and the
shelves were bolted together. Bolting by the use of screws and nuts
is a long and tedious task, and in addition, the use of bolts
further adds to the complexity of the display apparatus as well as
to the overall cost of the apparatus.
Accordingly, it is an object of the present invention to provide a
new and improved display apparatus which may be rapidly assembled
and disassembled.
It is another object of this invention to provide a new and
improved display apparatus which does not require the use of bolts
for maintaining the shelves on the supporting structure, yet
results in a rigid and strong support for display products.
It is still a further object of the present invention to provide a
new and improved display apparatus which has an open look design so
that product visibility is available from all four sides of the
display apparatus. Furthermore, it is desirable that items stacked
on the shelves of the improved display apparatus may be removed
from any of three sides, thereby aiding the shopper, and increasing
the flexibility of the subject display apparatus.
It is another object of the present invention to provide a new and
improved display apparatus which is inexpensive, yet is extremely
durable for constant reuse as required.
These and other objects are obtained by the provision of a display
apparatus comprising a generally vertical frame structure defined
by two vertical side structures including horizontal support
members, and a bracing means for interconnecting the vertical side
structures. Each supporting shelf is generally rectangular in plan
form, and has the edges thereof cut off at an angle in order to
enable the side edge portion to be folded. Two opposite side edge
portions are folded about three generally parallel lines so as to
form U-shaped clip portions which may be snap-locked onto the
horizontal support members of the vertical side structures. The
remaining two opposed side edge portions of the shelf are folded
about two generally parallel lines, so as to form a beam or
reinforcing member which extends along the span of the shelf
thereby aiding in the rigidity of the entire display apparatus. If
desired, one or both of the reinforcing members may be bent so as
to be positioned above the plane of the shelf so as to provide an
edge to prevent the inadvertant toppling of stacked goods from the
shelf. The reinforcing members also provides a surface for pricing
or labeling.
For a better understanding of the invention, reference should be
made to the following detailed description and to the drawings in
which:
FIG. 1 is a perspective view of the improved display apparatus of
the subject invention;
FIG. 2 is a plan view of a sheet of material preparatory to being
bent about the dotted lines to form a shelf for use in the subject
display apparatus;
FIG. 3 is a side view of a shelf of the subject invention;
FIG. 4 is a sectional view taken along line 4--4 in FIG. 3; and
FIG. 5 is a detailed sectional view taken along line 5--5 in FIG. 1
and illustrating in detail the interconnection between a shelf
member and a horizontal support member of the subject display
apparatus.
Turning to FIG. 1 the display apparatus 10 of the subject invention
generally comprises a frame assembly 12 for supporting a plurality
of shelves 14. The frame assembly 12 includes two vertically
extending side structures 16 which are interconnected by a bracing
means 18. The bracing means 18 may take the form of two rods 19
which are suitably attached, as by bolting, to the vertically
extending side structures 16. Each of the latter includes two
elongated rods 20,20 interconnected by a plurality of horizontal
support members 22 of generally rectangular cross-section, whereby
each side structure 16 is in the form of a ladder construction. The
horizontal support members 22 of the respective side structure
16,16 are located at the same heights for maintaining the shelves
14 in a generally horizontal diposition.
Each shelf 14 is secured to a repective support members 22 by an
interference or snap fit so that no bolts or other type of
fastening means are required.
FIG. 2 illustrates a generally rectangular sheet 24 which may be
suitably bent so as to form a shelf 14. More particularly, the
corners of each rectangular sheet 24 are cut at an angle, indicated
by the numeral 26, so as to enable the side edge portions,
designated by the letters A,A', B and B' to be folded to define the
shelf 14. The opposite edge sides B,B' are folded along crease
lines 30,32 and 34 in order to define the structure for cooperating
with the horizontal support members 22. Each side edge portion B,B'
is first folded 90.degree. upwardly about the line 30, after which
the edge portion is folded 90.degree. in the opposite direction
(downward) about the hinge line 32, followed by the subsequent
folding of the side edge portion about the crease line 34
downwardly 90.degree.. The result is a U-shaped clip portion,
designated by the numeral 42 in FIG. 3, with the clip portion being
of rectangular cross-section corresponding to the rectangular
cross-section of the horizontal support member 22. The dimensions
of the clip portion 42 are suitably controlled so as to result in
an interference or tight fit with the horizontal support member 22
(see FIG. 5), so that the shelf must be snapped into place onto the
horizontal support member. Hence, additional fastening means such
as bolts, etc., are not required for maintaining the shelves in
place.
Referring to FIG. 2, each side edge portion A,A' is first folded
downwardly 180.degree. about the crease line 40. Subsequently, the
side edge portion A is folded about the crease line 38, downwardly
90.degree., whereas the side edge portion A' is folded 90.degree.
upwardly sbout crease line 38. This results in the side edge
portion A' extending above the planar surface of the sheet 24,
whereas the side edge portion A extends below the surface of the
sheet 24. This is clearly illustrated in FIG. 4, while FIG. 3
illustrates that both side edge portions A,A' extend substantially
along the entire span of the shelf intermediate the U-shaped clip
portions 42. Note that each portion A,A' extends perpendicular to
the plane of the sheet 24. Accordingly, the provision of the
upstanding edges A,A' relative to the planar surface of the
rectangular sheet 24 effectively define beams which act to increase
the rigidity and load carrying capability of the shelf 14.
In the assembly of the subject display apparatus, after the frame
assembly 12 has been assembled, it is merely necessary to snap each
shelf 14 into place onto the associated horizontal support members
22. In like manner, disassembly of the display apparatus is readily
achieved by merely disengaging the U-shaped clip portions 42 from
the associated horizontal support members 22.
The display apparatus of the subject invention provides a new and
improved shelf structure of low cost construction which may be
readily assembled and disassembled. In addition, the subject
display apparatus is attractive, and very functional in providing
sturdy shelving which is open on at least three sides to provide
maximum product visibility and accessibility.
While the invention has been described in connection with a
preferred embodiment of the subject apparatus, it is not intended
to limit the invention to those embodiments. On the contrary, it is
intended to cover all alternatives, modifications and equivalents.
For example, the corners of the rectangular sheet may be notched by
a rectangular or square cut in lieu of the angular cut 26. Also,
each vertical side structure 16 may be made of several sections
which are assembled by pins extending through the elongated rods
20,20, with sufficient diagonal bracing being provided for
strengthening the structure. Furthermore the cross-sections of the
horizontal support members 22 (and hence the slip portions 42) may
also be rectangular, round, or any other configuration which will
provide a strong interconnection for the display apparatus.
