DETAILED DESCRIPTION
[0038] Referring to the drawings, like reference numerals designate identical or corresponding features throughout the views.
[0039] A tent typically comprises a ground sheet and a canopy sheet. A support structure is provided by curved tent poles which are secured to at least one of these sheets so that the tent is self-supporting and has a partially enclosed internal space. As a tent is typically a fabric self-supporting structure, the fixture points for the poles are held in a fixed position by tension of the poles and the material between the fixture points.
[0040] A typical known tent 100 is shown in
[0041] In an embodiment of the invention two pairs of pocket elements (described in more detail below) are positioned at spaced apart locations near the corners of a substantially rectangular ground sheet. The pocket elements each have an opening for receiving the end of a tent pole. Respective pairs of pocket elements are located opposite each other along diagonals bisecting each of the corners of the ground sheet. The openings of each of the pocket elements in each pair face each other.
[0042]
[0043]
[0044] In an embodiment, two tent poles are used to provide a skeletal support structure to the tent. The ends of the first pole are secured in the first pair of pockets and the ends of the second pole are secured in the second pair of pockets. The poles are longer than the distance between a pair of pockets and are curved under tension away from the ground sheet. Thus, together the two poles provide a dome structure. The skeletal structure has sufficient height to provide a shelter in which one or more humans can be accommodated.
[0045] Between each pair of pocket elements, the ground sheet is in tension, also. This provides a base to the tent with relatively flat fabric stretched between the corners of the tent. The two poles may be fixed to each other at the point where they cross to provide rigidity and stability to the structure. Alternatively, or in addition, the poles may be fixed to the tent at some other point.
[0046] A canopy is provided to form at least a partially enclosed internal space to the tent, i.e. the walls and roof of the tent. The canopy may be secured to the ground sheet along the edges, to the tent poles, or both the ground sheet and the tent poles.
[0047] The canopy is stretched or otherwise arranged over the tent poles. The canopy comprises sleeves on the internal side through which the poles may be threaded. The sleeves secure the canopy to the pole structure and provide a third fixed point along the length of the poles to provide the pole structure with some stability.
[0048] Thus, when the tent is assembled, the at least one pair of pocket elements and the pole structure are located within the enclosed internal space of the tent. The arrangement of the skeletal support structure within the enclosed internal space enables much more flexibility as to the shape of the canopy. For example, the canopy may have a suitable shage so that it extends beyond the limits of the ground sheet and or pole structure. This provides for a covered area that is not under the pole structure. Where the canopy extends some distance from the pole structure, it may be provided with guy ropes or points suitable for pegging to the ground in order to provide tension to the canopy and maintain the desired shape.
[0049] In some embodiments, the tent may be provided with tension straps. These are strings, ropes, strips, ribbons or belts of material that is stronger than the sheet material when under tension to provide reinforcement to the sheet material. Tension straps may be secured to any part of the tent sheets, and are typically secured along lines which carry the maximum tension. Therefore, in many instances they will be secured between a pair of pocket elements.
[0050] The pocket elements will now be described in more detail. In one embodiment, the pocket is made from an elongate piece of flexible material which is arranged in a cone shaped configuration. The pocket is then secured to one of the tent sheets.
[0051]
[0052] Before the material is formed into the pocket shape it is generally elongate and may have an optional edging material along one edge. The first and second edges 355, 356 are the long edges of the elongate form and are opposite each other. In the embodiment illustrated, the second edge 356 of the formed pocket 350 has edging material 354. The third and fourth edges 357 are the short edges of the elongate form and are opposite each other.
[0053] To form the pocket shape, the material is curved around the mid-point of the first edge 355 so that third and fourth edges 357 are overlapping. The shape is similar to a cone, with the mid-point of the first edge 355 forming the apex of the cone 358. In order to fix the shape of the pocket 350, the material is stitched along the first edge 351 on the bottom 353 of the pocket through the overlapping pocket material. Also, the pocket may be stitched along the first edge 355 on the inside 351 of the pocket 350. Both lines of stitching may be seen on the bottom 353 of the pocket 350 in
[0054] Edging material is secured around the edge of the cone to reinforce the edge and prevent fraying. In the embodiment illustrated, the edging material 354 does not extend along the third and fourth edges 357 of the pocket 350. Instead these edges are folded over and secured by stitching.
[0055] In a preferred embodiment, at least one pair of pocket elements is secured to the fabric of the tent so that poles may be inserted in the pocket elements and to provide a skeleton support structure. Alternatively, pocket elements may be secured to tension straps, as discussed below.
[0056]
[0057] When the end of a pole is inserted in the opening of the pocket and put under tension it will be directed towards the closed end of the pocket, due to the shape of the pocket and the direction of the applied force. The back of the pocket will extend a small distance up the pole, and the sides of the pocket will be in tension.
[0058] The pocket elements are suitably sized so that one or more tent pole ends may be inserted in each pocket. In some cases, the pocket elements are sized to review two or more tent pole ends. The pocket may have internal compartments, to divide the pocket into sections, one for each pole.
[0059]
[0060] It is not necessary for the direction of the pole to exactly match the direction of the tension strap. Therefore, even where it is intended for two poles to be fixed in position by the same pocket and directed in diverging directions from the pocket, it is not essential that there are two tension straps.
[0061] Furthermore, pocket elements may be integrated into the straps. For example, by folding over a portion of the strap near an end and securing it to itself so that it forms a cone or similar shape.
[0062] In another arrangement the pocket elements may be formed from a simple strap section which is folded round and secured to make a stirrup. In securing the stirrup, the end would be enclosed for securing a pole within. Alternatively, the pocket elements may be made by securing an extra piece of material to the ground sheet or canopy sheet, in the same place as the sheet, along two sides thereby providing a flap under which the end of a pole may be inserted. In another arrangement, the pocket may be formed from a moulded plastic with holes included in the mould for securing to the tent. The examples given herein are not the only ways of how to form a pocket element and are not considered to be limiting. The advantages, as discussed herein, may be achieved by any number of different arrangements of forming pocket elements.
[0063] It is not essential that the pocket is positioned on a tension strap and it is not necessary for a tension strap to be present at all. The tension strap is provided as reinforcement along certain lines of the tent fabric. If the tent fabric is strong enough in the direction of tension when the tent is assembled, then additional reinforcement is not required.
[0064] Parts for a tent have been described above. The skilled person will be aware of the various materials and the type of construction commonly used to make each part. The invention is not limited to use of any particular material. Each part may be constructed from materials which have suitable properties for the use of the part.
[0065] In use, where the pocket elements are located on the ground sheet of a tent and tension straps are provided between each of the pocket elements within a respective pair, a first end of a pole is inserted in the first pocket of a pair of pocket elements. The pole is forced to flex by the user in order to insert the second end of the pole in the second pocket of the pair of pocket elements, as the pocket elements are spaced apart at a distance less than the length of the pole. Additional poles are inserted in additional pairs of pocket elements until the poles form the complete skeletal support structure.
[0066] While it is not required that any particular pole is used with a particular pocket element pair, some lengths of pole will be more suitable for a particular pair of pocket elements than others. For example, if the poles are too short then a lower than desirable structure will be formed. Alternatively, if the poles are too long then a higher than desired structure will be formed, or it will not be possible to flex the poles so that they will fit between a pair of pocket elements.
[0067] As the tent is assembled and the poles are inserted in the pocket elements, the ground sheet will be in tension. Initially, when only one pole is inserted, the ground sheet will only be in tension between the two ends of the pole. As more poles are inserted, this will extend to an area of the ground sheet.
[0068] Once all of the poles are inserted, a canopy sheet is positioned over the structure and is supported by the structure. In an alternative arrangement, the canopy sheet may comprise sleeves, or loops on the interior service. In this case, the poles are threaded through the sleeves or loops before the pole ends are inserted in the pocket elements. The sleeves or loops assist in locating the canopy sheet in the correct position relative to the support structure and ground sheet, and to ensure that the canopy stays in the correct position during use of the tent once it is fully assembled. In an embodiment, instead of sleeves or loops, the internal surface of the canopy sheet may comprise clips which may be attached to the poles after the skeletal structure is assembled.
[0069] In any event, the canopy sheet is positioned over the structure and is at least loosely secured to the skeletal pole structure. Thus, the poles and pocket elements are within an at least partially enclosed internal space. The edges of the canopy may be secured either to the ground sheet or to the ends of the poles near to the ground sheet so that the support structure is entirely covered. In this case an opening in one side of the canopy would be provided to allow access to the tent.
[0070] In some embodiments, the canopy may extend beyond the limits of the ground sheet or pole structure. The internal pole structure allows more flexibility to the external canopy than for conventional tents where the shape is substantially determined by the exo-skeleton of the external poles. In some embodiments, the pocket elements will be positioned near to the extremity of the ground sheet. Where the canopy extends beyond the limits of the ground sheet or pole structure, the pocket elements may be located elsewhere. Furthermore, the ground sheet and or canopy may be secured to the ground with pegs. The tent may further comprise guy ropes on the outer surface, which may be pegged also in order to provide the tent with additional tension and greater stability. Still further, additionally the tent may include a fly sheet or both inner and outer layers.
[0071] In some embodiments, pocket elements may be attached to the canopy or fly sheet of the tent instead of or in addition to the ground sheet. This will normally be where additional poles are provided in order to achieve more complex skeletal structure.
[0072] In another embodiment, the ground sheet and canopy may be permanently secured together by stitching the canopy to the ground sheet around the edges of the ground sheet. In such an arrangement the canopy would be provided with at least one opening for inserting the tent poles when assembling the tent and for entering the enclosed internal space when the tent is assembled.
[0073] While the tents described herein have been described as both rigid and stable, the skilled person will realise that an assembled tent has a certain amount of movement. As noted in the background section of the application, tent poles are typically flexible and they may bend when a force, external to the tent, is applied. For example, there may be some movement in the tent structure in high wind. However, the tent will remain assembled due to the balance of tension provided throughout the tent and the tolerance of the securing points of the skeletal structure.
[0074] While embodiments of the invention have been illustrated and described, it is not intended that these embodiments illustrate all possible forms of the invention. It is understood that various changes may be made without departing from the scope of the invention.
