A suspendable structure 10 in the form of a suspendable tent 10 comprising of a flexible floor 12 and a network of suspension members 14, 16 for suspending the tent from a suitable suspension point. The suspendable tent 10 is conical shaped with a polygonal (or circular) floor 12. The suspendable tent 10 provides a single or sole suspension member 18 which is located at an apex 20 of the suspendable tent 10. The suspension means provides a single suspension point which solely supports and suspends the tent 10. The flooring 12 is intrinsically tensioned and an internal support strap 16 prevents the floor 12 from sagging. Accordingly, the present invention provides a suspendable tent 10 which does not require any guy ropes or other extrinsically secured tensioning and/or supporting and/or stabilising devices. The sole weight of the structure is entirely transferred through the single suspension point.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0097] As shown in
[0098] The suspendable tent 10 provides a tensioned polygonal (or circular) flexible floor 12 which is retained within an outer rigid peripheral frame 22. The flexible floor 12 provides a supporting surface which is tensioned within the peripheral frame 22. In particular, the tensioned floor surface does not significantly bow under the weight of a person or persons being supported on the tensioned floor surface. For example, the tensioned floor surface doesn't bow much when a person is lying thereon but does bow slightly or a bit when a person is standing thereon although the floor surface is tensioned so that it doesn't bow much.
[0099] The peripheral floor frame 22 is supported from the suspension member 18 by a plurality of peripheral support members 14. These support members 14 comprise fabric or textile straps (section of webbing) which extend between the peripheral frame 22 and the suspension member 18 located at the apex 20 of the suspendable tent 10.
[0100] In order to further support the flexible floor 12 and help prevent against the deflection of the tensioned floor surface, the suspendable tent 10 comprises an internal or auxiliary support member 16. The internal support member 16 extends between a part of the tensioned floor 12 and the suspension member 18. In particular, the lower end of the internal support member 16 is secured to a floor anchoring position 90 comprising a part of the flexible floor spaced from the periphery of the tensioned floor 12. More specifically, the internal support member 16 is secured to the tensioned floor 12 at a generally central location.
[0101] The height of the suspendable structure 10 is adjustable. The length of the internal support member 16 is adjustable with a buckling and tensioning system 82 for adjusting the floor level. For example, the internal support member 16 may comprise a buckle member 83 through which a further buckle member 82 can be engaged and the length of the internal support member 16 can be adjusted and held to set the (internal) height of the suspendable tent 10 (as shown in
[0102] The internal support member 16 extends from a (lower) distal end to an (upper) proximal end. As mentioned above, the proximal end is secured to a (non edge) central part of the floor 12 at an anchoring position 90. It should be appreciated that in some embodiments, this anchoring position 90 will not be located at geometrical centre of the polygonal (or circular) floor 12 but will be at a position spaced from the periphery of the floor 12. In addition, the distal end may have more than one physical location where it is anchored, for example two spaced locations.
[0103] As shown in
[0104] The internal support member 16 comprises lateral support sections 80 which extend between the two spaced apart longitudinal straps. The lateral support sections 80 may comprise spreader bars and provide step portions to enable a user to climb up the internal support member 16. These effectively create a rope ladder within the tent 10. For example, such a rope ladder may be useful to help place or reposition a fly-sheet 100 or canopy over the structure 10. A person will also be able to climb to a more elevated position to reach other locations.
[0105] The upper (proximal) end of the internal support member 16 provides a single connecting point where the two longitudinal straps converge and meet. The two longitudinal straps may actually be provided by a single strap returning on itself. This also provides a single connecting point to secure the internal support member 16 to the suspension system located at the apex 18.
[0106] As shown in
[0107] At the (lower) distal end, again the two longitudinal straps may converge towards connection points as shown in
[0108] These downward facing webbing loops 92, 94 may provide connection points to enable a rope or webbing ladder to be attached for access purposes when the floor hatch 50 is in either the open or the closed position. This may be particularly beneficial if the suspended tent 10 is suspended relatively high in a tree and it is not possible for a person or persons to easily reach and access the suspended tent 10. Such an external access ladder may also be joined to an additional external access ladder by way of carabiners in order to increase its length and increase access height. It may also be removed or placed within the suspended tent 10 in order to restrict access to the tent 10.
[0109] In
[0110] Alternatively, as shown in
[0111] To enter the suspended tent installed at height, a pair of external ladders (webbing or other material) may be attached (by way of carabiners or screw-link connectors) to the ladder-lugs 92, 94 located above the tensioning buckles 82, 83 at the distal (lower) ends of the internal support member 16, as shown in
[0112] The internal ladder-lug 92, 94 locations allow for exit or entry to and from the suspended tent 10 via the attached external ladders without undue stress or pressure upon or directly interfering with the angles or tensions of the mesh base/floor 12. This is particularly important when entering or exiting a suspended tent 10 already occupied by another user/person and or to avoid the potential hazards of loose/rolling or falling equipment.
[0113] This is achieved by locating the ladder-lug attachments 92, 94 at points (or point) situated suitably above the level of the mesh base/floor 12 and also attaching the external ladders independently of the mesh base/floor 12 and thereby taking the external ladders strain/loads directly through the internal support member 16 that is located/suspended above the height of the mesh base/floor 12.
[0114] The ladder-lugs 92, 94 internal location(s) may also allow for the external webbing ladders to be stored inboard of the suspended tent 10 for added security at night and/or when not in use.
[0115] This internal/external ladder configuration also allows for the suspended tent 10 to be entered entirely whilst a person is in the standing or upright position—allowing you to climb in and continue up and past the floor entry level to the top of the suspended tent—if necessary or required.
[0116] In an assembly with the ladder attached directly to the base/floor, the base/floor would be pulled directly downwards and towards the person (when the ladder is under load from a person climbing on it) and therefore pulls/slopes everyone and everything (equipment not tied down, etc.) that may already exist inside the structure. In particular, equipment etc will tend to move down and towards the base/floor hatch entry and directly in to the path of the person or other person climbing up or down the ladder.
[0117] The use of an internal support 16 member prevents the floor 12 from bowing significantly under the weight of a user(s). A flexible floor 12 which does not have the internal support member 16 coupled with the intrinsic tension within the floor surface 26 would tend to bow under the weight of a user. In particular, a floor on a suspended tent without such an internal (reinforcement) support may provide a hammock effect. Whilst this may be particularly suitable for some uses, such as providing temporary seating, the floor would not be suitable for prolonged use such as overnight sleeping.
[0118] The present invention provides a floor structure 12 which can be tensioned to a relatively high degree and this also aids the integrity of the floor 12. For example, the flexible floor 12 of the present invention provides a network or matrix of webbing sections which is very strong, as shown in
[0119] The suspendable tent 10 may comprise a fly-sheet 100 which may provide an outer wall for the conical tent 10, as shown in
[0120] The tent 10 provides multiple configurations and a user can customise the tent 10 for the situation. For example, the fly sheet covers 100, 102 and camouflage can be selected based on the temperature and weather conditions of the location. Similarly, the internal height of the tent 10 and also the suspension height can be individually adjusted to take into account the occupancy level and the environmental conditions, for example the wind.
[0121] The reinforcement members 24 comprise lengths of a webbing or fabric and these extend around the periphery of the conical tent 10 at intermediate positions. In the preferred embodiment, there is provided a lower reinforcement ring and an upper reinforcement ring. These rings of the flexible reinforcement material 24 are spaced apart from each other and are effectively concentric with each other and the peripheral frame 22.
[0122] As shown in
[0123] As shown in
[0124] The webbing matrix also comprises a first set of adjustable tensioning sections 42 which extend from a central ring 41 to an edge of the flooring surface 12. The webbing matrix also comprises a second set of adjustable tensioning sections 44 which extend diametrically across the polygonal (or circular) floor 12 and connect between opposing edge portions of the flooring surface 26.
[0125] The two sets of adjustable tensioning sections 42, 44 enable the tension of the flooring surface 26 to be manually adjusted to create the required tension. The adjustable tensioning straps 42, 44 may comprise a buckle mechanism 43, 45 through which the end of the strap 42, 44 is securely held. Such manually controlled buckles 43, 45 are commonly used to retain tension within a strap by preventing the end of the strap 42, 44 being pulled through the buckle 43, 45 by the tensile force placed on it. Furthermore, the buckle mechanism 43, 45 enables the strap 42, 44 to be easily tensioned by allowing the strap 42, 44 to be manually pulled through the buckle 43, 45 in a tensioning direction. Finally, the tension within the strap 42, 44 may be released or reduced by pivoting and/or placing the buckle 43, 45 at an angle relative to the direction of the strap 42, 44 to enable the tensile force to pull the strap 42, 44 through the buckle 43, 45.
[0126] The floor 12 provides a peripheral sleeve retaining enclosure into which the peripheral frame 22 is located. In particular, the peripheral frame 22 comprises a modular frame having 6 or 8 individual arcuate frame members or a number of arcuate frame members. The longitudinal ends of each arcuate frame member is arranged to be secured to an adjacent end of an adjacent arcuate frame member. Accordingly, the arcuate frame members are all connected and secured together to form a contiguous hoop or ring frame 22.
[0127] The arcuate frame members may comprise arcuate box sections and/or have a rectangular cross section or other profile. The vertical height of the frame members is arranged to be greater than the width (radial extent) since this helps to strengthen the peripheral frame 22. The preferred embodiment of the suspended tent 10 does not use cylindrical tubes for the arcuate frame members since these may not withstand and hold the significant tensile forces generated within the flooring surface 26.
[0128] The peripheral frame 22 is provided in a modular form to enable the suspendable tent 10 to be portable. For example, the peripheral frame may be dismantled to provide a kit which is comparable to a standard portable tent.
[0129] As mentioned above, the floor 12 provides a peripheral sleeve retaining enclosure into which the peripheral rigid frame 22 is located and the individual arcuate frame members can be slidably placed. For example, the sleeve relating enclosure provides a number of tensioned entrance regions into which the individual frame members can be inserted. In particular there may be the same number of entrance regions as there are frame members. One of the entrance regions may be more elongate in order to help the final connection to be made to complete the hooped/ring peripheral frame 22.
[0130] Whilst inserting the frame members and constructing the peripheral ring frame 22, the flooring surface 26 is maintained in a relatively slack (untensioned) state. This helps the frame members to be inserted and secured together. This also helps the final frame connection which is made to complete the frame ring which could otherwise be problematic.
[0131] The outer ends of the radial straps 42, 44 are secured to edges of the flooring surface 26. The radial straps 42, 44 are arranged to stretch and tension the flooring surface 26 within the circular peripheral frame 22. The flooring surface 26 comprises a polygonal (or circular) flooring material which has outwardly extending tapered sections having the tensioning buckle 43, 45 secured at the tips thereof. The tapering sections are arranged to be pulled over and around the frame 22 such that the tensioning straps 42, 44 locate on one side of the peripheral frame 22 and the actual flooring surface 26 locates on the second side of the peripheral frame 22. In this arrangement, the tensioning straps 42, 44 are pulled inwardly from below the floor and this effectively shortens the length of the radial (diametrical) tensioning straps 42, 44. The ends of these straps 42, 44 are secured to the outer edges of the flooring surface 26 and this thereby pulls the edges of the flooring surface 26 towards each other on the lower side of the peripheral frame 22 which thereby causes the flooring surface 26 to be stretched and tensioned. As described above, the flooring surface 26 overlaps the peripheral frame 22 and is stretched over the peripheral frame 22.
[0132] The use of the manually adjustable tensioning straps 42, 44 enables the user to place the flooring surface 26 under significant tension. The flooring arrangement together with the internal support member 16 thereby prevents or inhibits the floor from becoming bowed and providing a hammock effect.
[0133] The flooring surface 26 comprises an open material or mesh. This creates an airy internal environment. The use of a mesh may also prevent access to insects whilst still allowing the atmosphere to freely circulate which may be useful in warm/hot climates. A textile base cover 102 (shown in
[0134] As shown in
[0135] The entrance region 50 comprises a section of the floor 12 which can be at least partially disconnected to provide a passageway through the floor 12. For example, straps/buckles 52 or other closing mechanism is provided to create an opening flap within the floor 12 and to part the floor at the created edges 53. The buckles 52 or other closing mechanism also enables the tension within the floor 12 to be maintained when the flap is closed.
[0136] As shown in
[0137] In order to access the tent 10, the buckles 53, 55 (or other securement mechanism) are used to enable the flap 50 to fall away from the opening aperture whilst the flap 50 remains attached along the outer annular edge. Conversely, buckles 53, 55 are operated to close the opening and to provide a load bearing portion of the floor 12.
[0138] The door flap 50 includes two radial straps 54 (shown in
[0139] The bottom cover 102 (see
[0140] The suspendable tent 10 comprises lateral support (reinforcement) members 24 which extend around the periphery of the suspendable tent 10. The suspendable tent 10 comprises two lateral support members 24. The lateral support members 24 comprise sections of webbing which extend around the periphery of the suspendable tent 10 in a spaced apart configuration. The lateral support members 24 are concentric support members and these are spaced apart along the outer conical surface or outer conical periphery of the suspendable tent 10. These lateral support members 24 are stitched at intersections to the peripheral support members 14. The lateral support (reinforcement) members may comprise a (rigid) retaining frame constructed of a number of sections. For example the frame may be similar to the peripheral support frame 22 or retaining frame 72 in that a number of rigid poles may be secured together to form a hoop or ring.
[0141] As shown in
[0142] The fly-sheet 100 may be substantially conical in shape and located over the frame provided by the suspendable structure 10. The lower edge of the fly-sheet may be secured to the peripheral frame member 22 and the other end may be secured around apex 20. For example, the fly-sheet 100 may have a central opening which also includes an adjustable waterproof sealing ring in an apex through which the suspension mechanism 18 may project. The fly-sheet 100 may provide windows which may be opened. The main fly-sheet 100 and/or the base fly-sheet 102 may provide windows which may be opened.
[0143] As shown in
[0144] In the middle of this webbing intersection and attached to the underside may be one pair of shorter webbing lengths (or similar) that may cross each other at an angle of 90° and which may also be attached in the centre as well as at the outer ends in order to create channels of a suitable width that may accept a draw-able length of cord like material at the outer ends, which may knot/tie together or lock-off to create a fixed length and/or a tensioned closed loop or ring, in order to contain/restrain or attach a knotted rope, swivel, carabiner or screw-link device.
[0145] The suspended tent 10 comprises a retaining section 70 (shielding section or shroud portion) which extends around a lower section of the tent 10, as shown
[0146] An upper edge of the retaining section 70 is secured to a retaining frame 72. A lower edge of the retaining section 70 is secured to the peripheral frame 22. In use, the material of the retaining section 70 is stretched between the axially spaced apart retaining frame 72 and the peripheral frame 22. The material of the retaining section 70 thereby provides an inwardly tapered cylindrical wall around a lower portion of the suspended tent 10. The lower edge of the material of the retaining section 70 is only connected to the peripheral frame 22 at discrete positions. This connection may be through an adjustable toggle system to enable the tension within the material of the retaining section 70 to be adjusted. As shown in
[0147] The retaining frame 72 comprises a rigid frame in the form of a hoop or ring. As with the peripheral frame, the retaining frame may comprises a number (3, 4, 5, 6, 7, 8 etc.) of individual frame members which are connected together to form a contiguous rigid ring frame 72. The retaining frame 72 may locate within a sleeve enclosure which is defined around the upper edge of the material of the retaining section 70. This sleeve enclosure and the material of the retaining section 70 may be stitched at intersections to the peripheral support straps 14.
[0148] The suspension means provides a single suspension point which solely supports and suspends the tent 10. For example, the suspended tent 10 may be solely supported at a single point from a tree, as shown in
[0149] The single suspension point provides an omni-pendular motion that aids sleeping and is easy to set up from the ground without having to climb another structure (e.g. the suspending tree or an adjacent tree) and provides easily adjustable hanging heights (e.g. it can be lowered in high winds).
[0150] The suspension means comprises a suspension member 18 in the form of a webbing loop. The suspension mechanism may incorporate a swivel mechanism to enable the suspendable tent 10 to rotate around its central longitudinal axis.
[0151] The suspendable tent 10 may have a height in the region of 2.5 to 3 metres which would enable a user/users to stand within the structure 10 (see
[0152] As shown in
[0153] The present invention provides numerous differences over current suspendable structures. For example, the present invention provides a structure which can be purchased and used without a tent covering and so provides a suspendable platform (or sensory motion platform), which also offers by way of accessories, various separate tent style covers e.g. fly-sheet, mosquito net, 3D camouflage netting.
[0154] The suspendable structure comprises four crossed straps that create eight ends, to connect to a main ring. The suspendable structure 10 does not include a trampoline type floor but is a hybrid of a warp knitted mesh fabric in conjunction with a stitched narrow woven webbing attached by way of open loop straps which are closed and fully adjustable through the use of rated aluminium safety buckles for tensioning—without the use of springs or elastic loops. The suspendable structure 10 includes two completely separate units (base structure and fly-sheet), which are not sewn together to give modularity to the suspendable platform/structure.
[0155] The peripheral frame of the suspendable structure 10 comes in eight sections providing an even more compact product. The suspendable structure 10 is constructed of aluminium box section and warp knitted polyester fabric.
[0156] One particular feature of the present invention is the ladder system which is not attached or load bearing off of the base or side structure but loads separately and independently to the base or side structure and so aid stability when accessing the structure.
[0157] The centrally located internal support member allows two people to sleep next to each other without rolling to the centre. The suspendable structure 10 supports a maximum weight of 250 Kg.
[0158] The suspendable structure 10 includes a rigid component (a tubular aluminium backrest ring) above the rim level, and a mesh safety panel all around the structure—which rises up from the base ring and attaches to the backrest ring. The main structure door opening is secured by way of safety buckles & webbing making it load bearing when secured in the closed position. The suspendable structure 10 is provided in a separate wearable kit-bag and is not sewn-in to the structure.
[0159] It may be possible to have more of a frustum cone in shape but the main embodiment of the present invention is more conical and does not stop short of the top of the structure but actually extends over the top of the structure creating a waterproof sealing ring and not a large open aperture.
