FOLDABLE SUPPORT STRUCTURE
Abstract
A self-supporting foldable support structure comprises a
vertical standard having a main panel and a pair of stiffener ribs
extending longitudinally in planes generally normal to the plane of
the vertical standard and in the nature of an easel. Structure is
provided for causing the stiffener ribs to move to stiffening
position in the nature of a platform for the display of articles in
front of the vertical standard. Said structure comprises a front
wall spaced from the vertical standard with a foldable wall
extending from each end of the front wall and toward the vertical
standard. Each foldable wall consists of hingedly connected wall
portions, one of same being secured to a correlative stiffener rib
and the other being hingedly connected to a correlative end of the
front wall. The platform panel is hingedly connected to the front
wall, and resilient means are connected between the platform panel
and the vertical standard and are arranged to bias the platform
panel to a position resting upon the tops of the foldable walls and
tending to straighten the line of fold between the wall portions
and thereby move the stiffener ribs to stiffening position.

Claims
We claim:
1. In a self-supporting foldable support structure adapted to be
vertically free standing:
a. a vertical standard having a main panel and a pair of stiffener
ribs extending longitudinally thereof in planes generally normal to
the plane of said main panel;
b. structure for causing said stiffener ribs to move to stiffening
position and for providing a platform for the display of articles
in front of said vertical standard comprising:
i. a front wall spaced from said vertical standard;
ii. a foldable wall extending from each end of said front wall
toward said vertical standard;
iii. said foldable wall comprising hingedly connected wall
portions;
A. one of said wall portions being secured to a correlative
stiffener rib, and
B. the other of said wall portions being hingedly connected to a
correlative end of said front wall;
iv. a platform panel hingedly connected to said front wall;
v. resilient means connected between said platform panel and said
vertical standard and biasing said platform panel to a position
resting upon the tops of said foldable walls and tending to flatten
the angle between said wall portions and to move said stiffener
ribs to stiffening position.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The structure according to the present invention relates generally
to self-supporting support structures which can be shipped in a
folded or K-D condition and readily erected at the point of use for
display purposes.
2. The Prior Art
A structure of the general type is disclosed in Thomas U.S. Pat.
No. 3,508,734 (CL 248/459). The structure according to the present
invention constitutes an improvement of that shown in the aforesaid
Thomas patent in that the movement of the components to the erected
position is accomplished by a structure having the function also of
providing a platform for the display of an article of commerce, if
desired. Moreover, the structure according to the present invention
is enabled to be shipped in a K-D or folded condition, if desired,
the support platform being resiliently biased to a position to
cause the vertical standard to have stiffener ribs extending
therefrom acting in the nature of an easel.
THE DRAWINGS
FIG. 1 is a perspective view showing the support standard according
to the present invention being erected from a K-D condition
thereof;
FIG. 2 is a view similar to FIG. 1 showing a further step in the
erecting of the structure of FIG. 1;
FIG. 3 is a view similar to FIG. 2, but showing the structure in
the erected position thereof; and
FIG. 4 is a bottom view of the erected structure seen in FIG.
3.
The improved foldable support structure according to the present
invention is denoted generally by the reference numeral 10 and
consists of a vertical standard 11 having a transverse score line
13 therein whereby the standard 11 may be folded transversely
midway of the length thereof. Vertical standard 11 has a pair of
spaced stiffener ribs 12 extending therefrom, these being foldably
connected to the standard 11 along fold lines 12A. Upper and lower
display boards DB may be secured in any convenient fashion above
and below the transverse score line 13. Such display boards may
have any suitable indicia thereon or suitable devices for holding
articles of trade.
Structure is provided for causing the stiffener ribs 12 to move to
a stiffening position in planes generally normal to the plane of
the vertical standard 11 and to function in the nature of an easel
for the same. Such structure also provides a platform for the
display of articles in front of vertical standard 11 and the
display boards DB thereon.
Said structure includes a front wall 14 spaced from the vertical
standard 11, and a foldable wall 16 extends from each end of the
front wall 14 and toward the vertical standard 11. The foldable
wall 16 consists of hingedly connected wall portions 17 and 18,
these being connected along a vertical hinge line 19. Each of the
wall portions 18 is secured, as by adhesives or the like, to the
lower end of a correlative stiffener rib 12, and the other wall
portion 17 is hingedly connected at 20 to a correlative end of the
front wall 14.
A platform panel 21 is hingedly connected along fold line 22 to the
top of front wall 14. Platform panel 21 has a stiffener flange 25,
and structure is provided for biasing the platform panel 21 to the
position seen in FIG. 3. Such structure includes a resilient band
24 connected at one end to a fastening ear 23 formed as part of the
stiffener flange 25, the other end being secured at 26 to the lower
end of the standard 11.
The action of the resilient band 24 is to cause front wall 14 to
move away from the standard 11, the platform panel moving to a
position where it rests upon the tops of the wall portions 17 and
18. In so doing, the angle between the wall portions 17 and 18
tends to be flattened along the line of fold 19, and in the
flattening of the angle therebetween, the stiffener ribs 12 are
caused to adopt positions generally normal to the plane of the main
panel 11.
