FOLDABLE STEPPED DISPLAY STANDS
This invention relates to stepped display stands and particularly relates to
merchandise
display stands including a foldable display having a plurality of shelves in a
stepped
configuration and removably mounted on a foldable support base.
Display stands made of cardboard or corrugated paper board are widely used for
showing
varieties of merchandises. Such stands are convenient to erect, low cost to
produce and providing
adequate durability for repeated uses. A stand may also be made by stamping
its configuration on
a single cardboard and then folding the various parts of the configuration to
form the stand
having both the display tray and the integral support base. Pictures and
various decorations and
advertising information may be printed on the stand for attracting the
consumers's attention and
interest of the merchandise. One drawback of such display stand is that the
merchandise is placed
within a tray such that it is not visible to the consumers and the merchandise
is difficult to be
removed from the tray for selection and purchase. Such drawback is alleviated
by providing a
display portion in the form of a plurality of stepped shelves such that the
various items of the
merchandise placed on the stepped shelves are clearly visible and may be
conveniently selected
and removed for examination and purchase.
However, when the display shelves and the supporting base are integrally
formed with
one single cardboard configuration, it is cumbersome to erect by a single
person due to the
necessity to fold a plurality of parts while holding some of the parts that
have already been folded
in order to fold other parts. Furthermore, the entire integral display shelves
and supporting base
when unfolded to a collapsed condition for storage and transportation is
rather bulky for
packaging.

pushing the opposite
corners of the base outwards to disengage the extension tab 102 from the
retaining opening 103
and then also pushing the panels 67 and 75 outwards to fold along vertical
fold lines 98 and 99.
The elastic cord 104 will be in a tension state when the support base 12 is
folded in the collapsed
condition so that the support base may be easily erected by merely allowing
the tension of the
elastic cord 104 to pull the pivotal panel 100 back to the diagonal position
to unfold the support
base as well as to maintain it in the erected condition.
A second embodiment of the shelving portion 11 having reinforced shelves as

The shelving portion 11 of the display stand 10 of the second embodiment may
be formed
by first folding the first panel 14 upwards relative to the second panel 15
along the horizontal
fold line 20 until they are perpendicular to each other. The extension portion
25 and 26 are folded
upwards relative to the panel 15 until the triangular portions 114 and 116 are
perpendicular to the
panel 15 with the upper edge of the triangular portions 114 and 116 now facing
rearward to abut
with the side edges 38 and 41 respectively. The reinforcing side panels 107
and 108 are then
folded forwards as shown in Figure 11 to cover over the triangular portions
114 and 116
respectively. The vertical slots 37 and 40 engage with the rectangular cut
outs 119 and 121 to
provide two vertical side mounting openings now facing sideways from the rear
edge of the
folded reinforcing side panels 107 and 108. The triangular portions 113 and
117 may then be
folded outwards along the fold lines 11 S and 118 as best shown in Figure 12
to wrap over the
-11-
CA 02487751 2004-11-18
already folded reinforcing side panels 107 and 108 and they may be mounted in
place by bending
the mounting tabs 120 and 122 to insert into the two vertical side mounting
openings so as to
provide the reinforced side walls 25 and 26 for panel 15.
The reinforcing panel 105 may now be folded upwards relative to the panel 15
along the
horizontal fold line 143 until it lies juxtaposed to the front portion of the
under-surface of the
panel 15 to provide reinforcement to the upper shelve of the display.
After the upper shelve has been formed as described above, the panel 16 is
folded
downwards relative to the reinforcing panel 105 along horizontal fold line 21
until panels 16 and
105 are perpendicular to one another. The panel 17 is then folded upwards
relative to the panel
16 along horizontal fold line 22 until panels 16 and 17 are perpendicular to
one another so that
the panel 16 forms the vertical rear wall and the panel 17 formed the platform
respectively of the
second shelve of the display 10. The reinforced side wall of the second shelve
are formed by first
folding the triangular portions 123 and 126 of the side extension of the panel
17 upwards relative
to the panel 17 along vertical fold lines 45 and 48 respectively until the
triangular portions 123
and 126 are perpendicular to the panel 17 and their rear edges are in abutment
with the now
vertical panel l6.The openings 43 and 46 now form two mounting openings along
the rear edges
of the second shelve. The reinforcing side panels 109 and 110 are then folded
forwards to lie
juxtaposed to the outer surface of the triangular portions 123 and 126
respectively and the cut
outs 129 and 137 at the upper edges of the triangular portions 123 and 126 are
aligned with the
openings 43 and 46 respectively. The reinforced side walls of the second
shelve are finally
formed by folding the trapezoidal portions 124 and 127 downwards to wrap over
the reinforcing
side panels 109 and 110 respectively and the trapezoidal portions 124 and 127
are secured in the
-12-
CA 02487751 2004-11-18
place by bending the mounting tabs 130 and 132 inwards to engage with the side
openings 43
and 46 respectively.
The reinforcing panel 106 is then folded upwards relative to the panel 17
until it lies
juxtaposed to the front portion of the under-surface of the panel 17 to
provide the reinforcement
for the second shelve of the display.
The lower shelve may now be formed in the manner similar to the second shelve
by first
folding the panel 18 forwards relative to the reinforcing panel 106 along the
horizontal fold line
145 until they are perpendicular to one another and the panel 18 will be
positioned vertically to
form the rear wall of the lower shelve. The panel 19 is then folded forwards
relative to the panel
18 along horizontal fold line 24 until they are perpendicular to one another.
The triangular
portions 133 and 138 of the side extensions of panel 19 are folded upwards
along fold lines 63
and 66 respectively until they are perpendicular to the panel 19 and their
rear edges contact the
side edges of the panel 19. The reinforcing panels 111 and 112 are folded
forwards to lie in
contact with the outside surface of the triangular portions 133 and 138
respectively and the
openings 49 and 51 aligned with the cut outs 136 and 141 respectively form two
side mounting
openings at the rear edge of the shelve. The trapezoidal portions 134 and 139
are folded along
fold lines 135 and 140 respectively to wrap over the reinforcing panels 111
and 112 respectively
and they are secured in place by bending the mounting tabs 137 and 142 to
engage with the side
openings 49 and 51.
The reinforcing shelving 11 is mounted to the support base 12 in the manner
similar to
the first embodiment described above. Since all exposed surfaces of the
shelving of this
embodiment are formed by the same front surface of the shelving configuration
provided on the
-13-
CA 02487751 2004-11-18
cardboard, decorative material such as print or color may be simply provided
on the single front
surface of the configuration.
A third embodiment of the shelving portion 11 having full reinforcement of its
various
parts is shown in Figures 13 through 16. In this embodiment, A vertical
reinforcement panel 146
is provided for reinforcing the panel 14 so as to form a reinforced vertical
rear wall of the upper
shelve of the shelving portion 11. The reinforcement panel 146 is formed in
the configuration by
an additional rectangular panel extending upwards from the upper edge 161 of
the panel 14 as
best shown in Figure 14 so that the upper edge I61 provides a horizontal fold
line between the
reinforcing panel 146 and panel 14. Two mounting tabs 147 and 148 are formed
at the upper free
edge of the reinforcing panel 146. Two horizontal slot openings are formed in
panel 15 along the
horizontal fold line 20. Vertical slot openings 153, 154, I57, 158, I62 and
163 are formed in
panels 15, 17 and 19 respectively along their side edges. Mounting tabs 151
and 152 are formed
at the outer edge of the triangular portions 113 and 117 respectively of the
side extension
portions of the panel 15 and mounting tabs 155, 156, 159 and 160 are formed at
the lower edge
of the trapezoidal portions 124, 127, 134 and 139 respectively.
The upper shelve of the third embodiment is formed by first folding the
reinforcement
panel 146 forwards along the horizontal fold line 161 until it lies in front
and in contact with the
panel 14 to form the reinforced rear wall of the upper shelve. The
reinforcement panel 146 is
maintained in place by engaging the mounting tabs 147 and 148 with the
horizontal mounting
openings 149 and 150 respectively in the panel 15 as best shown in Figure 16.
The panel 15 is
then folded upwards relative to the panel 14 until the two panels 14 and 15
are perpendicular to
one another. The reinforcing side panels 107 and 108 are folded forwards until
they are
-14-
CA 02487751 2004-11-18
perpendicular to both the panels 14 and 15 and are aligned with the side edges
of the panel 15.
The triangular portions 114 and 116 of the side extension portions of the
panel 15 are folded
upwards until they are in contact with the outer surface with the
reinforcement side panels 107
and 108 respectively. The reinforced side walls of the upper shelve may then
be formed by
folding the triangular portions 113 and 117 inwards to wrap over the
reinforcing side panels 107
and 108 respectively and they are secured in this mounted position by engaging
the mounting
tabs 151 and 152 with the vertical slot openings 153 and 154 respectively.
The reinforcing panel 105 is folded to lie underneath the front portion of the
panel 15
similar to the second embodiment above to provide the reinforcement for the
upper shelve.
The rear wall and the platform of the second shelve are formed by folding the
panel 16
relative to reinforcing panel 105 to form its vertical rear wall and panel 17
relative to panel 16 to
form its horizontal platform.
The reinforced side walls are formed by first folding the reinforcing side
panels 109 and
110 forwards until they are perpendicular to both panels 16 and 17 and are
aligned with the side
edges of the panel 17 respectively. 'The triangular portions 123 and 126 are
then folded upwards
relative to the side edges of the panel 17 until they are in contact with the
outer surface of the
reinforcing side panels 109 and 110. The trapezoidal portions 124 and 127 are
folded inwards to
wrap over the reinforcing side panels 109 and 110 and they are secured in
place by engaging the
mounting tabs 155 and 156 with the mounting openings 157 and 158 respectively.
The horizontal reinforcing panel 106 is folded upwards until it lies in
contact with the
undersurface of the front portion of the panel 17 to provide the reinforcement
of the second
shelve.

The rear wall and the horizontal platform of the lower shelve are formed by
folding the
panel 18 relative to reinforcing panel 106 along horizontal fold line 145 and
also by folding the
panel 19 relative to panel 18 along fold line 24 similar to that in the second
embodiment as
described above.
The reinforced side walls of the lower shelve are formed in the manner similar
to the side
walls of the second shelve by first folding the reinforcing side panels I 11
and I 12 forwards until
they are perpendicular to both panels 18 and 19 and are aligned with the side
edges of the panel
19. The triangular portions 133 and 138 are folded upwards along the side
edges of panel 19 until
they lie in contact with the outer surface of the reinforcing side panels 111
and 112. The
trapezoidal portions 134 and 139 are then folded inwards to wrap over the
reinforcing side panels
11 l and 112, and they are secured in place by engaging the mounting tabs 159
and 160 with the
mounting openings 162 and 163 respectively.
An additional panel 164 is formed in the configuration extending outwards from
the
lower edge I65 of the panel 19. This additional panel 164 is folded downward
until it lies
underneath the front portion of the panel 19 and it may be secured to the
panel 19 with adhesive
so as to provide the reinforcement of the lower shelve.
While the present invention has been shown and described in the preferred
embodiments
thereof, it will be apparent that various modifications can be made therein
without departing
from the spirit and essential attributes thereof, and it is desired therefore
that only such
limitations be placed thereon as are imposed by the appended claims.
