Description




FIELD OF THE INVENTION




The present invention relates to tent suspension assemblies, and more specifically to tent pole holders of tent pole foot assemblies within tent suspension assemblies.




BACKGROUND INFORMATION




Tent suspension assemblies are well-known in the art. A tent generally includes a fabric shelter supported by a suspension assembly. Tents are popular portable shelters insofar as they often can be easily assembled and disassembled. Assembly of a tent typically involves the creation and proper balancing of tension during construction of the suspension structure. Disassembly involves the release of such tension. Tents are often more easily disassembled than assembled. The extent to which a tent is easily assembled is an important consideration to a consumer when deciding between tent models.




Several tent suspension assemblies are known in the art. Some of the more common types include the use of ropes, poles, stakes, and frames. External suspension assemblies use items surrounding a tent to create the tension necessary to suspend the fabric in order to define an interior space. Such an assembly may rely on driving a stake into the ground, hooking a latch to a frame, or tying a rope to a tree. External suspension assemblies may use, for example, poles held in place with grommets in conjunction with stakes driven into the ground. Grommets are typically affixed into webbing that is sewn to the tent. The tip of a tent pole is inserted into the grommet. With the tip of the tent pole in the grommet, force is exerted to tear out of the webbing, rendering it useless.




Other assemblies use poles and the fabric of the tent itself to create internal tension. Such an assembly uses the fabric to suspend poles of a skeletal-type frame to which the assembly is that it may be a self-contained suspension assembly independent of the surroundings, possibly allowing the tent to be lifted and moved without disassembly.




Self-contained suspension assemblies may have several including greater stability, flexibility of use, and ease of construction. Greater stability may arise if the tent is not reliant on the tension created by an external source, such as a stake that may become uprooted by movement inside the tent. flexibility of use in that they may be used in places where the location does not permit tethering, such as atop a rock mass. Moreover, a self-contained suspension assembly may be easier to construct inasmuch as no hammering or tying may be necessary.




However, even self-contained suspension assemblies have certain disadvantages regarding construction. A typical version of a self-contained suspension assembly includes several tent poles and pockets sewn into the fabric of corners of the tent, into which the tent poles are inserted. With one end of a pole inserted in a pocket at one corner of the tent, the pole may be inserted through loops or sleeves on the perimeter of the tent fabric. Once the pole is attached to the tent perimeter, the other end of the pole is inserted into a pocket sewn into a far corner of the tent. Because the pole is used to create the tension needed to suspend the fabric, the pole may need to be bent before being inserted into the far corner pocket.




Another version of a self-contained suspension assembly is known as a ring and pin system. A ring and pin system uses pins that are inserted in tent poles. The pins are slidably attached to rings that are attached to the tent. The pins have diameters smaller than the inner diameter of the tubular end of the tent pole. The tent poles are held in place on the pins only by the force of the poles against the pins. In the absence of tension, the pins are free to move around, the rings move around, and the pins freely move in and out of the tent poles.




Generally, the tension of a pole used to suspend a tent assembly is a useful force so long as it is controlled to serve its purpose. However, this tension may become troublesome. For example, tension created as a pole is being bent may cause the end of the pole wedged into the first corner pocket to wiggle out of the pocket into which it is inserted. Consequently, the pole may spring out of the pocket as the straightening of the pole releases the tension. Similarly, if using a pole-in-grommet assembly, a first pole tip inserted into a first grommet may become dislodged when attempting to insert the opposite pole tip into its opposing grommet, requiring the first tip to be reinserted into the first grommet. These events may cause much frustration to a person attempting to assemble a tent with many such poles.




Furthermore, even once the pole is suspended between two opposing corner pockets or grommets, the tension from the pole may cause, over time, the pocket or grommet to rip away from fabric to which the pocket or grommet is sewn. Due to the fact that a tent pole often ends in a narrow tip, the majority of the pole tension may be focused on a small surface area of the tip, resulting in a high concentration of pressure at the point at which the pole tip meets the pocket or grommet, respectively. This concentration of force may be sufficient to break down a seam that holds a pocket or a grommet to the tent, either by ripping the fabric or by loosening the stitching. If a pocket or grommet becomes detached, nothing is holding down the pole, and the tension is released. A tent may become unusable if a critical pole may no longer be held in place because a pocket or grommet is missing.




It therefore would be advantageous to design an assembly by which a tent pole may be held in place that would have the benefits of easy and reliable assembly, but avoid several of the shortcomings associated with the use of pockets or grommets in securing the poles.




SUMMARY OF THE INVENTION




The present invention relates to tent suspension assemblies, and more specifically to tent pole holders of tent pole foot assemblies within tent suspension assemblies. A tent pole holder according to an exemplary embodiment of the present invention may include a flat, paddle-shaped handle at a first end, a mid-section, and a partially-cylindrical extension at a second end.




The flat, paddle-shaped handle at the first end may have one or more slots through which straps may attach the tent pole holder to the tent fabric. The mid-section connects and supports the handle and the extension, and it may serve as a place at which to grip the tent pole holder while engaging and disengaging a tent pole. The partially-cylindrical extension at the second end may be inserted into a tubular end of the tent pole that the tent pole holder is intended to engage. The partially-cylindrical extension may include an o-ring that is slightly recessed along the partially-cylindrical extension so as to provide a tighter seal with the tubular end of the tent pole.




The tent pole holder may be attached to the tent fabric anywhere that tension between the tent fabric and the tent pole is desired. An engagement mechanism, such as the o-ring, may be used between the tent pole holder and the tent pole to prevent the tent pole from slipping off the tent pole holder.

DETAILED DESCRIPTION




Beginning with

FIG. 1

,

FIG. 1

shows a tent pole holder


100


according to an exemplary embodiment. Tent pole holder


100


may include, for example, a flat, paddle-shaped handle


101


at a first end


102


, a mid-section


103


, and a partially-cylindrical extension


104


at a second end


105


.




Flat, paddle-shaped handle


101


at first end


102


may have one or more slots


106


through which straps


501


may attach tent pole holder


100


to a tent


400


(shown in FIG.


5


). Mid-section


103


may serve as a place at which to grip tent pole holder


100


while engaging and disengaging a tent pole


300


. Partially-cylindrical extension


104


at second end


105


may be inserted into a tubular end


301


of tent pole


300


that tent pole holder


100


is intended to engage. Partially-cylindrical extension


104


may include, for example, an o-ring


200


(as shown in

FIGS. 3A-3C

,


5


) that fits within a groove


107


formed near second end


105


along partially-cylindrical extension


104


so as to provide a tighter seal with tubular end


301


of tent pole


300


.





FIGS. 2A-2E

show tent pole holder


100


from a variety of perspectives according to another exemplary embodiment.

FIG. 2A

shows a top view;

FIGS. 2B and 2C

show angled perspectives; FIG.


2


D shows a side view; and

FIG. 2E

shows a front view. Mid-section


103


is shown as having, for example, a tapered, reinforced, hourglass shape, but the appearance of mid-section


103


may vary widely. Mid-section


103


serves to connect and provide structural support between handle


101


and partially-cylindrical extension


104


, so mid-section


103


may be any shape that accomplishes these purposes.




Similar to

FIGS. 2B and 2C

, a typical tent pole holder


100


would be, for example, approximately 2.25 inches long, with some variation, for a typical tent pole foot assembly


500


. Tent pole holder


100


may be made of, for example, metal or hard plastic. For example, tent pole holder


100


may be made of cast aluminum to be strong yet light. Likewise, tent pole


300


may be made, for example, of metal or plastic, depending on the nature of its use.





FIGS. 3A-3C

show an o-ring


200


according to an exemplary embodiment. Referring to

FIG. 3B

, o-ring


200


could be slightly wider in its outer diameter


201


than the inner diameter


302


of tubular end


301


of tent pole


300


(shown in FIG.


5


), so that a tight seal is formed between o-ring


200


and inner diameter


302


. As tent pole holder


100


is inserted into tent pole


300


, outer diameter


201


of o-ring


200


flattens, causing friction between tent pole holder


100


and tent pole


300


. Likewise, for example, o-ring inner diameter


202


may be slighter narrower than a diameter


108


of groove


107


formed on tent pole holder


100


, so that o-ring


200


remains in place (shown in

FIGS. 2A

,


2


D). O-ring


200


may be made, for example, of rubber to facilitate placement in groove


107


because o-ring


200


would need to stretch over second end


105


before being rolled into groove


107


. By contrast, diameter


109


of partially-cylindrical extension


104


would, for example, approximately match but not exceed inner diameter


302


of tubular end


301


of tent pole


300


, to provide a tight fit but still permit insertion and removal of partially-cylindrical extension


104


from tubular end


301


.




The seal formed by o-ring


200


is a simple, reliable engagement mechanism


203


between tent pole holder


100


and tent pole


300


. In one exemplary embodiment, approximately 1.5 kg*9.8m/s


2


of force may be required separate tent pole holder


100


with o-ring


200


from tent pole


300


(i.e., equivalent to the gravitational force exerted by a 1.5 kg weight when suspended from a vertical tent pole holder


100


).




Alternatively, other engagement mechanisms


203


may be used instead of an o-ring


200


seal. Engagement mechanisms may be either self-releasing, as in o-ring


200


under appropriate force, or manually-releasing, as with some twisting or screwing mechanisms. As shown in

FIGS. 4A-4E

, possible engagement mechanisms


203


that may be employed include, for example, a spring-loaded ball bearing/groove mechanism


204


(

FIGS. 4A

,


4


B), a threaded nut/bolt-style mechanism


205


(FIG.


4


C), a spring-loaded tooth/slot mechanism


206


(FIG.


4


D), and a tooth/slot twist mechanism


207


(FIG.


4


E).





FIG. 5

shows tent pole holder


100


attached to a tent pole foot assembly


500


according to an exemplary embodiment. Tent pole holder


100


may be attached to tent fabric


400


anywhere that tension between tent


400


and tent pole


300


is desired, such as at a corner


401


where a tent pole pocket or grommet might otherwise have been placed to hold tent pole


300


. Instead of placing tent pole


300


into a tent pole pocket or grommet as in the prior art, tent pole


300


may engage tent pole holder


100


directly as tent pole holder


100


may be inserted into tubular end


301


of tent pole


300


.




Tent pole holder


100


may be attached to tent


400


by a strap


501


forming a holder loop


502


and a stake loop


503


. Strap


501


may be secured to tent


400


by, for example, stitching


504


and a box tack


505


. Holder loop


502


may pass through slots


106


of flat paddle


101


and may be closed by stitching


506


. Stitching


506


serves to restrict the outward movement of tent pole holder


100


. Holder loop


502


may also pass through a side-squeeze fly buckle


507


, which may be used as an attachment point for a rain fly that would contain the other half of the buckle


507


mechanism. Stake loop


503


could be used to secure tent


400


to the ground if necessary.




Once tent


400


has been constructed, tent pole


300


presses against tent pole holder


100


, keeping tent pole


300


securely in place. Strap


501


of holder loop


502


more evenly distributes the force of the tent assembly by pulling in the direction of the tent fabric


400


, instead of perpendicular to tent fabric


400


. As tent


400


is being assembled, however, engagement mechanism


203


, such as o-ring


200


, may be used between tent pole holder


100


and tent pole


300


to prevent tent pole


300


from slipping off tent pole holder


100


. Engagement mechanism


203


is designed to prevent unintentional removal of tent pole


300


from tent pole holder


100


, while providing only minimal resistance to the intentional disengagement of tent pole


300


from tent pole holder


100


.




With tent pole


300


engaged to tent pole holder


100


, the remainder of the tent suspension assembly may be more easily assembled, without worrying about a far end of tent pole


300


slipping while a near end of the pole is being positioned. Moreover, the tent suspension assembly gains additional stability from the combined effect of engagement mechanisms


203


between tent poles


300


and tent pole holders


100


. Therefore, once fully assembled, the tent suspension assembly is less vulnerable to an unintentional disassembly that might be caused by movement within or around tent


400


.
