Description
FIELD OF THE INVENTION
[0001] The present invention relates to collapsible structures and,
more particularly, to a tool that facilitates an individual
erecting the collapsible structure.
BACKGROUND OF THE INVENTION
[0002] Temporary shelters that can be easily transported and
rapidly set up have been in existence for sometime. These shelters
can be useful for emergency situations to provide temporary care
shelters as well as outdoor recreational situations to provide
protection from the environment.
[0003] Some early collapsible shelters have frames comprising
X-shaped linkages, telescoping legs, and a canopy covering the
framework such as the shelter described in U.S. Pat. No. 4,607,656,
titled QUICK ERECTION COLLAPSIBLE SHELTER, issued to Carter on Aug.
26, 1986, incorporated herein by reference. The legs of that
shelter are capable of telescoping to provide additional height,
and the framework of the X-shaped truss pairs is capable of
horizontal extension between the legs to support a canopy. Other
similar canopies described in the following patents, all
incorporated herein by reference, U.S. Pat. Nos. 4,641,676;
4,700,862; 4,779,635; 4,947,884; 5,404,962; 5,485,863; 5,490,533;
5,511,572; 5,632,292; 5,632,293; 5,797,412; 5,813,425; 5,865,127;
5,921;260; 5,934;301; 6,070,604; 6,076,312; 6,129,102; 6,206,202;
6,230,729; 6,240;956; 6,412,507; 6,431,193; 6,520,196;
[0004] Of course, numerous variations on the above collapsible
canopies exist to increase structural integrity, headroom, and the
like. One such improvement is described in U.S. Pat. No. 5,701,923,
TITLED COLLAPSIBLE SHELTER, issued to Losi et al. on Dec. 30, 1997,
incorporated herein by reference. The shelter described in that
patent uses a non X-shaped linkage assembly capable of folding in a
manner similar to the above referenced structures, but instead of a
back-to-back X linkages, uses an intermediate linkage to increase
headroom and structural integrity.
[0005] While a great improvement over prior art structures, one
drawback of all of these structures is that they are designed to be
erected by two or more people, and they are difficult to erect from
the collapsible state to the expanded state by a single operator.
Thus, it would be desirous to provide an apparatus and method that
would facilitate the erecting of a collapsible shelter from a
collapsed state to an expanded state.
SUMMARY OF THE INVENTION
[0006] To attain the advantages and in accordance with the purpose
of the invention, as embodied and broadly described herein, a tool
that facilitates the erecting of a collapsible shelter is provided.
The tool comprises a grip portion and a lever portion.
[0007] The present invention also provides methods for using the
tool that facilitates the erecting of a collapsible shelter. The
method comprises arranging a collapsible shelter in its collapsed
state. The tool is attached to the shelter and the shelter is
erected.
[0008] The foregoing and other features, utilities and advantages
of the invention will be apparent from the following more
particular description of a preferred embodiment of the invention
as illustrated in the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWING
[0009] The accompanying drawings, which are incorporated in and
constitute a part of this specification, illustrate embodiments of
the present invention, and together with the description, serve to
explain the principles thereof. Like items in the drawings are
referred to using the same numerical reference.
[0010] FIGS. 1 and 2 show a representative erecting operation
without using the present invention;
[0011] FIG. 3 shows an apparatus for facilitating the erection of a
shelter in accordance with the present invention;
[0012] FIG. 4 shows another apparatus for facilitation the erection
of a shelter in accordance with the present invention; and
[0013] FIGS. 5-9 show a user using the apparatus of FIG. 3 in the
erection of a shelter in a manner consistent with the present
invention.
DETAILED DESCRIPTION
[0014] The present invention will now be described with reference
to FIGS. 1-9. FIG. 1 is representative of a collapsible shelter 20
in a mostly collapsed state. FIG. 2 is representative of
collapsible shelter 20 in a mostly expanded state. Two users 22 are
shown at opposing sides of collapsible shelter 20 in FIGS. 1 and 2.
Users 22 grasp linkages 14 and move away from each other in the
direction shown by the arrows A in FIG. 2 to move the collapsible
shelter 20 from the collapsed to the expanded state. With at least
two users 22, the erecting of shelter 20 is relatively easy and
quick.
[0015] When only one user 22 is available to erect the shelter,
erecting shelter 20 is rather difficult. In particular, one user 22
generally travels around shelter 20 to move each side a little at a
time. Alternatively, one user 22 could attempt to stand at one spot
and try to force shelter 20 open; however, this requires
significant leverage and strength.
[0016] FIG. 3 shows a perspective view of an apparatus or tool 300
capable of allowing a single user 22, as shown in FIGS. 7-9, to
provide increased leverage to facilitate a single user 22 erecting
shelter 20 alone. While tool 300 is useful in facilitating the
erection of shelter 20 by a single person, tool 300 would also be
useful if two or more users 22 were attempting to erect shelter 20.
Tool 300 includes a fitted portion 302 and a lever portion 304.
Fitted portion 302 includes sidewalls 306, a cover 308, and
protrusions 310. Sidewalls 306, cover 308, and protrusions 310 form
a cavity 312 adapted to fit snuggly to legs 314, which is best seen
in FIG. 9. Fitted portion 302 means portion should be generally the
same shape as the leg(s), but the tool can have some play when
attached to leg(s) 314. Also, while shown as a rectangular tool on
a rectangular leg, other geometric shapes and combinations are
possible. For example, instead of 90-degree sidewalls 306 as shown,
the sidewalls could form an arc or curve that fits relatively
snuggly with a rectangular leg. While tool 300 is shown attached to
leg 314, one of ordinary skill in the art would know recognize that
tool 300 could be designed with a fitted portion that would attach
to linkage 14 instead of leg 314. Although tool 300 could be fitted
to linkage 14, it is believed leg 314 is better able to withstand
the leverage better than linkage 14.
[0017] Fitted portion 302 can be designed to slip over leg 314 such
that tool 300 is coupled to leg 314 by sliding cavity 312 onto leg
314, or tool 300 can be designed to snap onto leg 314 by applying
lateral pressure. Lever portion 304 can be wrapped with a padding
316 as shown or left as a rigid material. It is believed the
padding would provide comfort to user 22, however. Moreover, fitted
portion 302 can have various combinations of sidewalls, top (or
bottom), and protrusions as a matter of design choice as long as
supplying pressure on tool 300 does not cause excessive slippage of
tool 300 in relation to leg 314, which could cause injury.
[0018] FIG. 4 shows a tool 400 for use with taller shelters 20.
Tool 400 includes lever portion 304 and fitted portion 302, but
fitted portion 302 is separated from lever portion 304 by an
extender 402. The separation of fitted portion 302 and lever
portion 304 can cause difficulty in stabilizing tool 400 so a
stabilizer 404 can be provided. Stabilizer 404 comprises at least
one stabilizing wall 406, but can have two (as shown) or more
walls. Stabilizer 404 would not need to be a snug fit around leg
314, but would be to prevent excessive lateral movement of tool
400.
[0019] Tool 300 and tool 400 could be constructed as single
integrated pieces using, for example, injection molding. But, it is
contemplated that lever portion 304 and fitted portion 302 can be
separate parts capable of being coupled together using a connector
330. Connector 330 could be, for example, a screw fitting, a snap
fitted, pin and detent fitting, or the like. Using a connector 330
would allow for easy conversion between tool 300, without the
extender 402, and tool 400, with the extender 402. Basically,
extender 402 would be designed with a matching connector such that
fitted portion 302 can be separated from lever portion 304 and then
fitted portion 302 and lever portion 304 could be coupled to
opposing ends of extender 402.
[0020] Referring now to FIGS. 5-9, a procedure for using tool 300
to erect shelter 20 is described. First, shelter 20 is arranged in
a spot (not labeled in the FIGS.) where it is to be erected. User
22 attaches tool 300 to one leg 314. User 22 would then grasp legs
314 and/or linkage 14 and begin opening (or expanding) shelter 20.
While user 22 could use tool 300 at this stage of deployment, it
has been found that the strength and leverage needed for the
initial portion of expanding shelter 20 is not significant and
frequently it is easier to initially open shelter 20 without using
the tool.
[0021] Once tool 300 is in place and shelter 20 is partially
expanded, user 22 grasps linkage 14 and/or leg 314 such that tool
300 provides an anchor of sorts allowing user 22 to provide
increased force or leverage to facilitate additional expansion of
shelter 20. As shown in FIG. 7, it is contemplated that user 22
would wedge lever portion 304 of tool 300 between the body of user
22 and the arm of user 22. Thus, tool 300 would assist in the
application of force when user 22 pulls on linkage 14 and/or legs
314.
[0022] As shown in FIG. 9, once shelter 20 is largely deployed in
the expanded state, user 22 can apply leverage by resting the
forearm of user 22 on lever portion 304 of tool 300. This will
assist in the final expansion of shelter 20 and the locking of
shelter 20 in place. As can be seen, it would be possible to mold
tool 300 into shapes designed to fit body parts of user 22, such
as, for example, lever portion 304 could be molded so the forearm
of user 22 fits comfortably in a groove associated with the
padding.
[0023] While the invention has been particularly shown and
described with reference to particular embodiment(s) thereof, it
will be understood by those skilled in the art that various other
changes in the form and details may be made without departing from
the spirit and scope of the invention.
