COLLAPSIBLE FOOT LOCKER OR TRUNK
Abstract
A collapsible trunk in which the walls of the lid and body are
pivotally secured to the top and bottom panels respectively by a
continuous flexible strip. The walls are secured to each other by
rigid edge securing means in the form of angle irons. The trunk is
knocked down by removing the corner angles and the angle irons that
are held by the few bolts. The walls then pivot about the flexible
strip to a planar position with their respective top or bottom
panel.

Description
BACKGROUND OF THE INVENTION
This invention relates generally to a collapsible trunk. More
particularly, the present invention is concerned with a collapsible
trunk which has unique and effective means for maintaining the
collapsible sides in collapsed form ready for being rapidly and
easily set up. Attempts have been made in the past to produce a
collapsible trunk in a simple and economical manner but possess
inherent undesirable characteristics. For instance, Arlitt -- U.S.
Pat. No. 2,752,018 discloses one approach that for many purposes is
unsatisfactory. One of the drawbacks is the lack of adequate
sealing between the juncture of collapsible panels, thus
facilitating the entry of dust, insects and moisture. To simply add
additional flanges to avoid these problems would substantially
contribute to the work in setting up the trunk and defeat the
purpose of achieving rapid set up.
OBJECTS OF THE INVENTION
It is the principal object of this invention to provide a
collapsible trunk or foot locker that may be easily and quickly
knocked down and set up.
Another object of the present invention is the provision of a
flexible means to permit all panels to be pivotally connected to
corresponding top and bottom panels.
A further object of the present invention is the provision of a
collapsible foot locker having flexible means between pivoting
flexible members forming the trunk and which flexible means is
continuous to provide a substantial sealing effect at the
edges.
Another object of the present invention is the provision of a
collapsible trunk having removable vertical edge securing means
which is rigid to secure adjacent vertical edges on respective
front, back and sides to the corresponding edges of the top and
bottom panels.
Yet a further object of the present is the bracing of corner angles
to overlap and protect the corners of the collapsible trunk.
These and other objects of present invention shall become readily
apparent upon careful consideration of the accompanying drawing,
wherein,

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring particularly to FIGS. 1 and 4 of the drawings, the
collapsible trunk of the present invention is generally depicted by
the numeral 10 as being composed primarily of a lid 12 and a body
14.
The body 14 is formed with a bottom panel 16, front, back and side
walls. The walls are secured to corresponding edges 26 of the
bottom panel 16 by means of a flexible, elongated and continuous
strip 28 that may be secured to the edges 26 of the bottom panel
and a corresponding adjacent edge 30 of each of the front, back and
side walls 18, 20, 22 and 24. As may best be seen in FIG. 6, a
space 32 is provided in knocked down condition between edges 26 and
30 in order to permit the pivoting of the walls about the bottom
panel and along the longitudinal axis of the flexible strip. The
space, as particularly shown in FIG. 6, should be of a dimension of
at least the thickness of the bottom panel. It is important that
the flexible strip 28 be continuous to maintain the trunk secure
and tight against moisture, dust and insects, and as such, is
desirably formed from well known materials such as flexible
fiberboard which may be suitably impregnated for waterproofness, or
plastics such as polyvinyl chloride to provide toughness and
waterproofness, or metal that is resilient and bendable. The strip
is secured to the bottom and the walls by means of rivets or tacks
34 which are suitably located along the longitudinal length of the
flexible strip. The flexibility of the strip is important in the
present invention since it provides the means for permitting the
trunk to collapse flat and at the same time when positioned in set
up condition will maintain the integrity of the inside of the
trunk. Depending upon the selection of the material for the
flexible and resilient strip, the toughness and scuff resistance
and lasting qualities can be such as to permit the trunk to be used
and even abused without any damage.
The side panels may be provided with one or more handles 36
suitably secured to the side. The front panel is also provided with
the handle 36 and a latch and locking mechanism 38 cooperating with
corresponding member on the lid 12. On each side thereof, there is
also provided a swinging latch member 40 which is secured to
complementary latch member on the lid. At the top of the rear wall
20 are hinges 42 which are also secured to a lid 12.
The lid is constructed in the same manner as the body 14 of the
trunk in that it is provided with a top panel 44, front, back and
side walls 46, 48, 50 and 52. Flexible strips 28 are identical to
those previously described and secured in the same manner. The
space 32 between the top panel and the front wall as may be seen in
FIG. 6 is of the same dimensions as that between the bottom panel
and front wall.
The hinges 42 are such as will permit a complete folding back of
the top rear wall 48 as shown in FIG. 6 in order to completely
collapse the trunk for knocked down condition.
When in substantially set up position as shown in FIG. 3, rigid
edge securing means in the form of angle irons 54 are provided.
These angle irons are secured to adjacent edges of the walls by
suitable means such as bolts 56. Corner angles 58 are positioned in
each of the bottom corners to overlap a portion of the flexible
strip 28 and the angle 54 as best shown in FIGS. 3, 4 and 5. The
angles 54 and the corner angles 58 are preferably of rigid
materials such as metal or hard, tough plastic such as polyvinyl
chloride, nylon, etc. to provide suitable protection for the
trunk.
A combination angle for both the corner and the sides is provided
for the lid 12 and is shown at 60.
The confronting edges of the lid 12 and the body 14 of the trunk
are preferably provided with complementary metal channels 62 on the
upper edges of the body and 64 on the lower edges of the lid. As
best seen in FIG. 6, channel 64 is provided with a protrusion 66
which is to be received in complementary groove 68 in the channel
62. When closed, the protrusion 64 fits into the complementary
groove 68 to provide a tight seal against moisture, insects and
dust.
In order to knock down the collapsible trunk, it is a simple matter
to remove the corner angles 58 and the angles 54 by means of the
few bolts 56 that are used to secure them and then perform the same
operation on the lid 12 to remove the combination corner angle 60.
The walls 18, 20, 22 and 24 of the body 14 fall down of their own
weight planar to the bottom and if the trunk is turned over, as
shown in FIG. 1, so that the inside of the trunk faces toward the
ground, the lid may be folded back on hinges 42 as shown in FIG. 6
to form the compact, knocked down condition as shown in FIG. 2 and
6. In this knocked down condition, the collapsed trunk may be
transported simply and easily or else put away during periods of
nonuse and may be stored or shipped in a suitable flat container,
as shown in phantom lines of FIG. 6, with substantial savings in
cargo space. For light, inexpensive trunks the savings achieved in
transporting a knocked down trunk as compared to a set up bulky
trunk is substantial.
