Definitions
- This invention relates generally to the field of indoor/outdoor enclosures. More particularly, the present invention relates to a portable tent. Even more particularly, the invention relates to a portable hunting tent.
- tents for camping, hunting, photography, or other uses have been available for a long time. These tents have evolved overtime. Early tent construction involved draping a protective covering over a series of vertical supports and anchoring the perimeter of the tent to the ground with rope ties. Later tent designs involved an exterior support system involving a series of rigid shaped supports sleeved through exterior sleeves on the outer surface of the tent wall, the supports arching over the tent and allowing the tent to hang from the supports and also be stretched and held open by the supports. In many cases these exterior supports crossed over each other in the shape of an ‘X’ for more stability. More recently, tents have been constructed with flexible rods also sleeved through exterior sleeves in the tent wall. These tents often have a dome shape and are supported by the arching action of a flexible rod whose ends are pinned in position.
- the window and door openings also include a portion of the tent wall material to cover the openings for more protection against exterior elements like cold and rain.
- the portion of material for covering the opening may simply be a flap of material which can be unfolded or unrolled and stayed with ties.
- the material may include zippers for opening and closing the door. These may occur on both the tent material portion and the screen covering the opening to facilitate passage through the opening.
- tent structures are often made of light weight materials, which can lead to only marginally sturdy enclosures.
- the fabrics of the tents can expand and shrink due to weather conditions or storage conditions. When they shrink, they can be difficult to assemble because they may not cooperate as well with the support structure. When they expand, they may tend to flap in the wind leading to noise. This flapping noise can be bothersome to those trying to enjoy the outdoors and may be even more detrimental to the outdoor experience where the tent is used for hunting or photographing wild animals. Worse yet, the flapping loose material can lead to tearing.
- tents are often made of several parts requiring assembly and making the tent difficult to set up.
- the cross-bracing can obstruct the view from the inside of tent.
- a tent frame includes at least three support legs, the at least three support legs having a connected end and a free end, the at least three support legs comprising a collapsible truss including at least two compression members, a hinge situated between the compression members, and a tension member extending from a first point near the free end to a second point near the connected end, wherein the at least three support legs are joined at their respective connected ends.
- the at least two compression members may include a roof pole and a wall pole.
- the hinge may include a hinge pin and the hinge may be adapted to allow relative rotation of the roof pole and the wall pole about the hinge pin, the relative rotation limited to approximately 235 degrees.
- the frame may further include a compression hub wherein the at least three support legs are joined at their respective connected ends via a pivotal attachment between the roof pole and the compression hub.
- the frame may further include a tension hub wherein the at least three support legs are joined at their respective connected ends via an additional attachment between the tension member and the tension hub.
- the support legs may further include telescoping rods extendable from the sleeve end of their respective wall poles.
- a tent frame in another embodiment, includes at least three support legs, the support legs each including a means for collapsing the support leg and a means for stabilizing the support leg when in a set up position.
- the frame may further include a means for actuating the stabilizing means.
- a method of setting up a tent includes providing a collapsible tent in the collapsed position, placing the collapsible tent on the ground thereby defining a center of the tent, unfolding at least three wall poles down about a first end from a generally vertical position to a generally horizontal position, each wall pole directed radially away from the center of the tent once unfolded, lifting at least three hinges diagonally upward away from the ground and outward away from the center of the tent, the hinge connected to an end of the wall pole near the center of the tent and connected to an end of a roof pole near the ground, wherein lifting the at least three hinges causes at least three support legs to be mostly formed, and tensioning at least three cables associated with the at least three support legs.
- a tent in still another embodiment, includes a collapsible frame and a shell adapted to cover the frame, the shell having at least one window opening and at least one window curtain covering the at least one window opening, the at least one window curtain being adapted to slidably open and close.

- a circumferential barrier to this type of motion is provided and folding the wall pole 116 in this manner is not feasible.
- the cable 120 may extend down the length of the wall pole 116 and be secured to the sleeve end 140 of the wall pole 116 with a loop connection similar to that included at the cable hub 126 at the top of the frame 102 .
- the loop may pass through a looped plate 200 which is secured with a bolt inserted into a threaded hole in the wall pole 116 .
- the length of the cable 120 between the attachment of the cable 120 to the sleeve end 140 of the wall pole 116 and the secured attachment to the cable extension arm 182 defines a predetermined distance.
- the predetermined length of the cable 120 between the sleeve end 140 of the wall pole 116 and the cable extension arm 182 naturally causes the cable extension arm 182 to be positioned as shown in FIG. 21 and prevents the cable extension arm 182 from rotating up past the concave receiving portion 198 .
- a spring ball 202 is shown projecting through a hole in the wall pole 116 .
- the spring ball 202 is positioned on the telescoping rod 118 such that when the telescoping rod 118 is extended out of the end of the wall pole 116 , the spring ball 202 snaps into place in the hole shown preventing additional outward movement of the telescoping rod 118 and also preventing inward movement of the telescoping rod 118 .
- Information regarding an alternative spring ball embodiment may be found in FIG. 77 or 78 .
- FIG. 24 a support leg 112 system without a tension cable 120 is shown.
- the geometry of the support leg 112 may cause the hinge 122 to tend toward collapsing.
- the geometry of the hinge 122 may prevent relative rotation in that direction and thus may act as a rigid connection between the roof pole 114 and the wall pole 116 .
- no relative rotation may be allowed between the roof pole 114 and the wall pole 116 and the support leg 112 may act as a continuous member with a bent shape.
- the deflected shape shown in FIG. 24 may result (exaggerated for purposes of explanation).
- a strut in the form of a cable extension arm 182 or other member may create a lateral force to the hinge location due to the tension in the cable 120 passing over the strut. As shown, this lateral force may induce a bending moment in the frame 102 opposite that caused by loading the structure. As such, the effect of the truss system may be to cause a deflected shape as shown in FIG. 25 (exaggerated for purposes of explanation).
- the net result may be a truss system with internal forces that are opposite to that of loading the structure.
- the deflected shapes of FIGS. 24 and 25 may counteract each other to create a frame 102 with compression members showing little or no bending deflection, the compression members being the roof poles 114 and wall poles 116 and the tension member being the cable 120 .
- the capacity and strength of the frame 102 may become more dependent on the compressive strength of the wall and roof poles 114 , 116 and the tensile strength of the cable 120 rather than the bending strength of the tall slender poles, 114 , 116 . This may create a much stronger system than if the truss system were omitted.
- a tent 100 with a shell 104 is shown according to certain embodiments.
- the tent 100 and associated shell 104 may have walls 204 and an associated roof 206 .
- the shell 104 of the tent 100 may or may not have a bottom 208 . Alternatively, it may simply have a partial bottom 208 around the perimeter of the tent.
- the tent shell 104 may be adapted to fit over a frame 102 similar to that previously described. As such, the shell 104 of the tent 100 may be adapted to rest on the cables 120 of the frame 102 as the cables 120 define the outer most portions of the frame 102 .
- the tent 100 may have window openings 210 in any or all of the walls 204 .
- the windows 210 may extend substantially all the way across the shell wall 204 and may be located in the upper half of the wall height.
- the window openings 210 may include a window screen 212 and a window curtain 214 (not shown).
- the shell 104 of the tent 100 may include peep holes 216 (shown closed) for viewing outside of the tent 100 when a window curtain 214 in a particular direction may not be open.
- the shell 104 of the tent 100 may be made from a variety of material including but not limited to canvas, vinyl, or other textiles known to resist wind, rain, and other natural elements.
- the shell 104 may be camouflage and the window screens 212 may also be camouflage while the window curtain 214 may be a solid color creating a background for the screen camouflage.
- the screens 212 may be a regular screen color and the window curtain 214 may be camouflage.
- both the window screen 212 and the window curtain 214 may be camouflage.
- the window curtain 214 may be made of the same or similar material as the shell 104 .
- the tent shell 104 may have shell channels 216 affixed to the edges of the window openings 210 for receiving the a corresponding curtain channel 218 affixed to the vertical edges of the window curtains 214 .
- the window curtain may also have pull tabs 220 in each of the corners of the window curtain 214 for sliding the window curtain 214 up and down.
- the pull tabs 220 in the bottom corners of the window curtain 214 may be pulled on to slide the window curtain 214 downward causing the window opening 210 to be exposed above the curtain 214 and also causing the window curtain 214 to lap along the inside face of the shell 104 below the window opening 210 .
- FIG. 28 shows the window curtain 214 pulled partially open and
- FIG. 29 shows the window curtain 214 pulled fully open.
- a rope 222 may be fastened to the tent 100 and further fastened to a rope knob 224 in the upper corners of the window curtain 214 as shown in FIG. 30 .
- the rope 222 may have a length and may be fastened to the tent 100 in a location so as to prevent the window curtain 214 from moving downward beyond the length of the shell channel 216 .
- the curtain channel 218 and the shell channel 216 may maintain an overlap of approximately an inch or more.
- the shell channel 216 extends 12′′ to 18′′ down beyond the bottom of the window opening 210 .
- the rope 222 and rope knob 224 may not be necessary as the overlap of the curtain channel 218 maintains sufficient overlap with the shell channel 216 to avoid falling out the bottom of the shell channel 216 . This maintains the window curtain 214 closer to the inside face of the shell 104 and prevents excess flapping and noise.
- the vertical sliding window curtain 214 may also be slid upward by grasping the pull tabs 220 in the upper corners of the window curtain 214 and pulling up on the window curtain 214 .
- FIG. 32A is a cross section view of a shell and curtain channel 216 , 218 in slidable mated position.
- the shell channel 216 and the curtain channel 218 may be identical reversible pieces to cut down on manufacturing costs. Alternatively, they may not be identical.
- the channels 216 , 218 may be made from flexible plastic material and may fit together with sufficient snugness to prevent the window curtain 214 from sliding inadvertently but sufficient looseness to allow the window curtain 214 to slide readily when the pull tabs 220 are pulled on. As shown in FIG.
- the channels 216 , 218 may have a tab portion 226 for sewing or otherwise adhering to the tent shell 104 or the window curtain 214 .
- the channels 216 , 218 may also have an interlocking portion 228 including a female receiving portion 230 and a male portion 232 adapted to allow relative longitudinal movement between the two channels 216 , 218 but not relative transverse movement in any direction.
- one of the channels 216 , 218 has only a female receiving portion 230 and the other channel has only a male portion 232 allowing the two channels 216 , 218 to be interlocked with a slidable relationship.
- the screens 212 are camouflage screens and are removable.
- the screens 212 may be attached to the window opening in a similar manner to that of a window curtain 214 . That is, the screen 212 may have a screen channel 236 sewn to its edge similar to that shown in FIG. 32A and the shell 104 may have a corresponding shell channel 234 sewn to the edge of the window opening 210 similar to FIG. 32A . As such, the screen 212 may slide up and down in a similar fashion as the window curtain 214 . As shown in FIG.
- the window channels 216 , 218 and the screen channels 234 , 236 may be nested next to each other to provide for the movement of both the window curtain 214 and the screen 212 separately or together.
- the channel affixed to the shell 104 may simply have two sets of channels: one for receiving the window curtain 214 and one for receiving the screen 212 .
- the screens 212 may be secured with hook and loop and may be removed prior to beginning hunting, photography, or some other activity where quiet removal is required.
- FIG. 91 an alternative geometry of the channels described is shown. This geometry could be used as a shell channel 416 , 434 or a window curtain/screen channel 418 , 436 .
- the tent shell may include collapsible/expandable peek/vent holes 216 for viewing outside the tent 100 or allowing air to flow in and out of the tent 100 when the window curtains 214 are closed.
- the peek holes 216 may be near the seam between the wall portion 204 and the roof portion 206 of the shell 104 and may be located toward the middle of the width of the wall 204 .
- a fabric sleeve 238 may be sewn to the inside face of the shell just below the peek hole 216 opening.
- a holder 240 with a bottom portion, an upper portion, and a plastic hinge may be positioned within the sleeve 238 and may extend up and out of the sleeve 238 such that the hinge portion of the holder 240 is located approximately at the top of the sleeve 238 and the upper portion extends beyond the sleeve 238 .
- the plastic hinge may allow the upper portion to lie substantially flat against the underside of the roof 206 .
- the upper portion of the holder 240 may be forced outward and upward causing the hinge of the holder 240 to allow the upper portion to rotate approximately 115 degrees relative to the lower portion of the holder 240 causing a V-shaped holder 240 directed into the interior of the tent 100 .
- the peek hole 216 may take the shape of a diamond and may have a camouflage screen permanently sewn in.
- the upper most end of the holder 240 may secure itself in the seam between the screen of the peek hole 216 and its attachment to the roof portion 206 of the shell 104 .
- the peek hole 216 may be approximately 16′′ wide by 4′′ high. Alternatively it may be larger or smaller.
- the peek holes 216 are shown from the outside of the tent 100 . It is noted here that the shape of the peek hole 216 and the nature of its support cause it to create an eave on the roof portion 206 of the shell 104 and also cause the screen of the peek hole 216 to be tilted downward below the eave and the portion of the shell 104 below the peek hole 216 to be tilted inward and upward. This allows the eave shape of the roof 206 to protect the peek hole 216 from water entry. Also, the downward directed screen helps prevent water entry and the upward facing portion of the shell 104 below the screen allows for water to run-off away from the opening.
- the tent may also include a door 242 in the form of a vertical openable seam extending from near the bottom of a tent wall 204 to near the top of a tent wall 204 .
- the seam may also travel laterally across the wall 204 near the top or bottom of the seam or both.
- the seam may be a secureable seam with hook and loop, a zipper, or other known securing devices.
- the zipper may be similar to a ziploc baggie with a slidable element that forces a longitudinal male and female element together, thereby providing a relatively quiet process of closing and opening.
- the use and set up of the tent 100 will now be described with respect to FIGS. 36-51 .
- the shell described above may be positioned over the frame 102 and the frame 102 may be in a collapsed position for portability.
- the collapsed frame 102 and shell 104 may be placed in a bag to form a backpack for even more portability as shown in FIG. 36 .
- This backpack assembly with the collapsed tent 100 included may range from approximately 5 lbs to 30 lbs depending on the size of the tent 100 and the materials used.
- the size of the collapsed tent 100 may range from approximately 4′′ in diameter to approximately 18′′ in diameter and have a length ranging from approximately 24′′ long to approximately 50′′ long.
- FIG. 37 the collapsed tent 100 has been removed from the back of the wearer and has been placed on the ground and initial preparations are made.
- FIG. 38 the first of five wall poles 116 are being folded down in the same way as that shown in FIG. 10 .
- FIG. 39 additional wall poles 116 are folded down until all wall poles 116 are folded down as shown in FIG. 40 .
- the next step, as shown in FIG. 41 may include grasping one of the roof poles 114 and pulling it upward to a position similar to that shown in FIG. 11 .
- FIG. 42 shows additional roof poles 114 being pulled upward into position until all roof poles 114 are pulled into position as shown in FIG. 43 .
- FIG. 44 shows the user having entered the tent 100 and extending the first telescoping rod 118 from the bottom of its wall pole 116 similar to that shown in FIG. 14 .
- FIG. 44 shows the user having entered the tent 100 and extending the first telescoping rod 118 from the bottom of its wall pole 116 similar to that shown in FIG. 14 .
- FIG. 46 shows the tent 100 after the crank assembly 156 has been turned causing the cable hub 126 to raise relative to the roof pole hub 124 and create tension in the cables 120 and thus drawing the shell 104 of the tent 100 taut. This is caused by the cable tension causing the frame 102 to extend upward and outward.
- FIGS. 47-51 show the fully set up tent 100 from various angles and in various positions.
- a partial bottom 208 is shown around the perimeter of the tent 100 .
- a full bottom 208 may be provided. The take down procedure may follow the steps above in the opposite order and variations will be apparent to those skilled in the art.
- the elements of the frame 102 may be constructed of most any material, including but not limited to steel, aluminum, various plastics, or other materials known in the art.
- the pole members 114 , 116 , 118 may be made from most any type of stiff or flexible pipe, tube, or rod.
- the poles could have any cross-sections from round to square/rectangular to triangular or any other geometric shape.
- all poles could have additional hinges or could telescope to create a preferred length.
- the frame 102 may be constructed of at least three support legs 112 and any number of additional support legs 112 .
- the frame 102 may be as few as one or two support legs where external support is provided.
- rods 318 may have a hinged attachment to the wall pole 116 and thus may have a collapsed position as shown. As the rods 318 are rotated about the hinged connection to a straight position generally parallel with the wall pole 116 , as shown in FIG. 53 , the tent frame 102 will rise in a similar manner as though a telescoping rod 118 had been extended. As shown in FIG. 54 , a hinge pin may be offset to cause the bottom end of the wall pole 116 to abut the top end of the rod 318 when the rod 318 is moved to its expanded position. As such, the rod 318 is prevented from over rotating.
- the cable 120 may be secured to the outer surface of the rod 318 .
- the tension from the cable 120 will hold the rod 318 in an expanded position preventing the rod 318 from collapsing.
- FIGS. 55-59 Another alternative embodiment is shown in FIGS. 55-59 .
- the cable 120 does not extend to the sleeve end 140 of the wall pole 116 .
- the cable 120 stops near the hinge end 132 of the roof pole 114 .
- the roof pole 114 does not extend all the way to the hinge 122 .
- a fiberglass extension pole 314 may be connected to the lower end of the roof pole 114 .
- the fiberglass extension pole 314 could be connected to the top of the wall pole 116 .
- the hoop tension provided by the shell 104 of the tent 100 holds the wall poles 116 in while the cable 120 pulls up on the roof poles 114 .
- FIG. 56 is similar to FIG. 55 , but includes a shell 104 draped over the frame 102 .
- FIG. 57 shows the frame 102 fully expanded and
- FIG. 58 shows the frame 102 fully expanded with a shell 104 in place.
- FIG. 59 is a close up view of the cable 120 , roof pole 114 , fiberglass extension pole 314 , and wall pole 116 of the embodiment shown in FIG. 55 . Also shown is a hinged connection between the fiberglass extension pole 314 and the top of the wall pole 116 .
- a hinge 322 between a roof pole 114 and a wall pole 116 is shown.
- a separate cable extension arm 182 is not included, but is instead incorporated into the wall pole portion 380 of the hinge 322 .
- the cable extension arm 182 is not free to rotate, the cable 120 does not need to provide it with stability by having a bushing that receives a steel ball.
- a free spinning pulley 382 is shown. It is noted that this may limit the amount of outward pushing force that can be generated by tensioning the cable 120 because the distance between the cable 120 and the hinge 322 is not as large.
- the leg of the hinge 322 supporting the pulley 382 could be extended in FIG. 60 , however, because of its rigid nature relative to the wall pole portion 380 of the hinge 322 , this would cause the collapsed frame 102 to occupy a larger volume.
- a roof pole hub 324 and crank assembly 356 are shown that allow for more quickly tensioning the cables 120 . That is, the roof pole hub 324 is not threaded and thus provides for slidable motion of the threaded rod 164 of the crank assembly 356 .
- the user may be able to simply press upward on the crank assembly 356 to create tension in the cables 120 .
- a threaded gear 360 may be engaged.
- the threaded gear 360 may be hinged and anchored by a spring as shown so as to pivot out of the way when the threaded rod 164 is advanced upward, but to maintain contact with the threaded rod 164 as shown in FIG. 61 . Thereafter, as shown in FIG. 62 , turning the threaded rod 164 will cause the threads of the threaded gear 360 to engage the threads of the threaded rod 164 and draw the threaded gear 360 down against the top of the roof pole hub 324 . The threaded rod 164 can then be further advanced by turning it. In addition, the threaded rod 164 is prevented from withdrawing from the roof pole hub 324 by the threaded gear 360 .
- the engagement of the threads on the threaded rod 164 with threads on the interior of the roof pole hub 124 may be selectively controlled with a lever which moves a clamping threaded gear 560 into and out of position. This may be similar to that found on a typical work piece clamp on a chop saw.
- crank assembly 156 , 356 may include a hydraulic pump, a scissor type lift, or a ratchet.
- the cable 120 could take the form of a rope, wire, strap, rod, or other tension member known in the art.
- the elements of the tent 100 may be made from plastic, aluminum, magnesium, or other suitable light weight materials.
- the following figures show elements adapted to be made from plastic. Those skilled in the art will understand and appreciate that several other elements of the tent 100 , not further described below, may also be made from plastic or other light weight materials.
- FIGS. 63 and 64 show a cable hub 326 according to one embodiment.
- the cables 120 shown include looped ends as before.
- the cable hub 326 includes upward projecting cylindrical portions 327 that receive the loops of the cables 120 .
- the surface of the cable hub 326 adjacent to the cylindrical portions 327 may be sloped to approximate the slope of the cables 120 as they travel toward the hinge 122 of the support leg 112 .
- a portion of the top surface of the cylindrical portion may also be sloped to facilitate easier attachment of the cables.
- the top of the hub 326 may be flat to accommodate a washer and a nut placed over the top of the hub 326 to secure the cables 120 in place and prevent them from slipping off the top of the cylindrical portions 327 .

- the solid bar 588 and the pair of plates 590 may be connected with a hinge pin 592 near the end of the plates 590 of the wall pole portion 580 and near the base of the solid bar portion 588 of the roof pole portion 578 .
- the upper surface of the wall pole portion 580 may be concave for receiving and nesting tightly against the bottom surface of the roof pole portion 578 and preventing further rotation once expanded.
- the outer surface of the roof pole portion 578 also may include a recess 525 adapted to receive a cable stop 523 .
- the cable 520 includes a loop at each end for attachment to the cable hub 326 at one end and an anchor point at the other.
- the cable 520 may include a cable stop 523 in position to fit into the recess 525 of the roof pole portion 578 shown in FIG. 71 .
- the roof pole portion 578 may also include a nub 527 on each side of the solid bar portion 588 for receiving a cable guide swivel 529 (not shown). For more information regarding a cable guide swivel see FIGS. 76 and 82 - 85 .
- FIGS. 73-75 Further details of the roof pole portion 578 and the wall pole portion 580 are shown in FIGS. 73-75 .
- FIG. 73 shows a butt end inside view of a roof pole portion 578 showing the tubular portion 584 and the solid bar portion 588 extending substantially orthogonally thereto with a concave slot for receiving the cable 520 and a nub 527 on each side for receiving a cable guide swivel 529 .
- FIG. 74 shows a top view of the roof pole portion 578 .
- FIG. 75 shows a butt end view of a wall pole portion 580 showing a tubular portion 584 and a pair of tabs or plates 590 extending substantially orthogonally thereto.
- FIG. 76 shows two views of a cable guide swivel 529 .
- the cable guide swivel 529 may be attached to the nubs 527 of the solid bar portion 588 of the roof pole portion 578 of the hinge 522 .
- the U-shaped cable guide swivel 529 may straddle the solid bar portion 588 and remain slightly offset from the surface of the solid bar portion 588 , allowing the cable 520 to pass there through and allowing the cable guide swivel 529 to pivot about the nubs 527 .
- the cable guide swivel 529 may also include a threaded stud 531 extending away from the hinge 522 for extension through a grommet on the shell 104 of the tent 100 acting as a support point for the shell 104 and allowing the shell 104 to be secured to the frame 102 .
- FIG. 77 shows an alternative embodiment of the attachment of the cable 120 to the sleeve end 140 of the wall pole 116 .
- the cable loop is looped around the wall pole 116 and also around a cable anchor 517 .
- the cable anchor 517 includes a raised protrusion 519 on an upper end, the raised protrusion 519 having a contour similar to that of an angled cable loop.
- the cable anchor 517 has a concave underside and is mounted on the wall pole 116 with two fasteners passing through the cable anchor 517 and into threaded bores in the wall pole 116 . Alternatively the bores may not be threaded and the fasteners may be rivets.
- the cable anchor 517 also includes a tunnel like structure 521 for securing a spring ball 502 .
- the spring ball 502 may be positioned within the tunnel 521 so as to force the ball portion 503 of the spring ball 502 against the surface of the wall pole 116 .
- the ball portion 503 of the spring ball 502 may be positioned outside a bore through the wall pole 116 . As such, when the telescoping rod 118 is in place in the wall pole 116 , the spring ball 502 is prevented from fully entering the bore. However, when the telescoping rod 118 is extended, the ball portion 503 of the spring ball 502 may fully enter the wall pole 116 and as such, may prevent the telescoping rod 118 from re-entering the wall pole 116 .
- a ring may be placed under the arm of the spring ball 502 to allow the ball portion 503 to be pulled from the bore and allow the telescoping rod 118 to be retracted.
- the elements of the connection are more clearly shown individually in FIG. 78 .
- the wall pole portion 780 may extend diagonally from the top of the wall pole 716 and may straddle the roof pole 714 .
- the wall pole portion 780 may be connected to the roof pole 714 with a hinge pin 792 .
- the wall pole portion 780 may also include a concave surface for nesting against the bottom surface of the roof pole 714 and preventing full rotation of the roof and wall pole 714 , 716 relative to one another and providing a stop point for the expansion of the frame 102 .
- the roof pole 714 may extend beyond the hinge pin 792 and have a slot 779 for receiving a tooth 781 of the cable extension arm 782 .
- the cable extension arm 782 may pivot about a pin located near the diagonal transition between the wall pole 716 and the wall pole portion 780 of the hinge 722 .
- the cable extension arm 782 may extend upward and outward and may have a tooth 781 for engaging the slot 779 on the end of the roof pole 714 .
- the cable extension arm 782 may also include a recess 725 for a cable stop 723 . Once in position, and the cable 720 is tensioned, the cable stop 723 will maintain an upward force on the cable extension arm 782 and maintain the tooth 781 of the cable extension arm 782 in the slot 779 of the roof pole 714 . As such, as long as there is tension on the cable 720 , the hinge 722 remains in a fixed position.
- FIG. 90 Still another embodiment of a hinge 1122 is shown in FIG. 90 .
- This hinge 1122 is similar to the hinge 722 in that the roof pole 1114 may extend beyond the hinge pin 1192 . However, rather than having a slot for receiving a tooth, the roof pole 1114 extends to the cable 1120 and has a recess 1125 for a cable stop 1123 .
- a support leg 112 is shown with an additional hinge 244 for tensioning of the cables 120 , and to shorten the length of the tent in its final collapsed position.

- These alternatives may include a leverage handle for extending the cable extension arm 182 to tension the cables 120 or include a threaded extension arm 182 that can be extended outward to tension the cables 120 .
- a hinge could be included in the wall pole 116 in lieu of the roof pole 114 or both could include a hinge.
- the roof or wall pole 114 , 116 or both could include a telescoping portion for extending each and thus tensioning the cable 120 .
- This could include a leverage handle for forcing the poles to extend and lock in place.
- the poles could screw outwards.
- turnbuckles could be used on the cables 120 to create the tension.
- the crank assembly 156 shown and described with respect to FIG. 17 is efficient in that it provides cable tension on all cables 120 through one central process.
- a combination of a moveable cable hub 126 may be used in conjunction with one of the above mentioned methods of tensioning the cables 120 . That is, the rod 164 extending through the roof pole hub 124 and supporting the cable hub 126 may be telescoped down in the collapsed position to save on the length of the collapsed tent 100 . Then, once the tent 100 was initially expanded, the cable hub 126 and rod 164 may be telescoped upward, slidably, screwed or otherwise, and locked in place. Once this initial process was complete, further cable tensioning methods mentioned above could be used.
- an alternative window curtain system is shown.
- the window curtain 414 shown in FIG. 81 is fastened to the bottom edge of the window opening 410 in the shell 104 .

- the top and bottom curtains 414 could be opened alone or in combination to created various heights of exposed window opening 410 .
- a thin opening may be at the center of the window opening 410 may be created so a sitting person can see straight out a approximately eye level. This embodiment may help prevent wind and water from entering the tent 100 when the curtain 414 is closed. This is in contrast to the sliding curtains 214 shown in FIGS. 27-30 which are not fixed to the shell 104 at their bottom or top.
- a window curtain 614 may slide to the side rather than vertically.
- a window opening 610 may not be as wide as shown in previous embodiments, thus allowing for room for the window curtain 614 to slide before intersecting with an adjoining wall.
- the window opening 610 may be a slot type window approximately 14′′ wide by approximately 3′′ to 4′′ tall and may be located at eye level. Alternative sizes will be apparent to those of skill in the art and are thus within the scope of the present invention.

- an extended threaded stud 931 is shown similar to that shown in FIGS. 82-85 .
- This extended threaded stud 931 may function to support a rain fly, which prevents water from resting on the surface of the shell 104 . As such, the rain is less likely to soak through the tent shell 104 . The presence of a rain fly may also allow for venting in the roof of the tent 100 without causing water to enter the roof.
- FIG. 89 shows a similar threaded stud 933 extending from the top of the cable hub 126 through the top of the tent shell 104 .

- the tent may include additional cables separate and apart from the cables 120 .
- These additional cables may be placed to provide additional lateral support in the form of cross bracing between adjacent support legs or in other positions that will stiffen the structure.
- These additional cables may be positioned to avoid causing obstructions within the tent and may also be positioned to avoid interfering with the collapsibility of the tent. It is noted that a plurality of positions will be apparent to those skilled in the art and are within the scope of the invention.
- the tent may be modularized so as to facilitate setting up a large tent. That is, several tents could be set up and placed adjacent to one another and the associated shells of the tents could be adapted to provide for one large fully or partially enclosed space.
- the tent described herein is advantageous for several reasons.
- the adjustability of the frame allows for a taut shell whether the shell has expanded or shrunk. This prevents noise due to the shell flapping from wind and may prevent damage to the shell. This may also add to the strength of the tent due to the circumferential tension provided to the wall poles. This leads to a third advantage, which is that the truss type system makes for a tent that is very sturdy and strong.
- Fourth, the window channels described herein allow for extremely quiet opening and closing due to the slidable channels used in lieu of zippers or hook and loop or other relatively noisy securing means. Moreover, the channels may hold the window curtains taut when closed further adding to the quietness of the tent.
- Fifth, the shape of the frame in conjunction with the shape of the shell and the location of the windows provides for unobstructed view out of the windows.

Description
- The present application is a continuation of U.S. patent application Ser. No. 12/248,532 filed on Oct. 9, 2008, which claims priority to Provisional Application with Ser. No. 60/998,274 filed on Oct. 9, 2007, titled Hunting Tent, the contents of which are hereby incorporated by reference herein.
- This invention relates generally to the field of indoor/outdoor enclosures. More particularly, the present invention relates to a portable tent. Even more particularly, the invention relates to a portable hunting tent.
- Tents for camping, hunting, photography, or other uses have been available for a long time. These tents have evolved overtime. Early tent construction involved draping a protective covering over a series of vertical supports and anchoring the perimeter of the tent to the ground with rope ties. Later tent designs involved an exterior support system involving a series of rigid shaped supports sleeved through exterior sleeves on the outer surface of the tent wall, the supports arching over the tent and allowing the tent to hang from the supports and also be stretched and held open by the supports. In many cases these exterior supports crossed over each other in the shape of an ‘X’ for more stability. More recently, tents have been constructed with flexible rods also sleeved through exterior sleeves in the tent wall. These tents often have a dome shape and are supported by the arching action of a flexible rod whose ends are pinned in position.
- Many of the later tent designs have been equipped with doors, windows, and air vents created by making openings in the material of the tent wall. These openings have included screening to allow air to flow through and keep out unwanted bugs or debris. Often, the window and door openings also include a portion of the tent wall material to cover the openings for more protection against exterior elements like cold and rain. In some cases, the portion of material for covering the opening may simply be a flap of material which can be unfolded or unrolled and stayed with ties. In the case of doors, the material may include zippers for opening and closing the door. These may occur on both the tent material portion and the screen covering the opening to facilitate passage through the opening.
- Many of the tent designs described, as well as other designs, suffer from several drawbacks. First, due to their temporary and portable nature, tent structures are often made of light weight materials, which can lead to only marginally sturdy enclosures. Additionally, the fabrics of the tents can expand and shrink due to weather conditions or storage conditions. When they shrink, they can be difficult to assemble because they may not cooperate as well with the support structure. When they expand, they may tend to flap in the wind leading to noise. This flapping noise can be bothersome to those trying to enjoy the outdoors and may be even more detrimental to the outdoor experience where the tent is used for hunting or photographing wild animals. Worse yet, the flapping loose material can lead to tearing. In order to make the support structure portable, tents are often made of several parts requiring assembly and making the tent difficult to set up. Finally, in the case of cross-braced supports, as described above, the cross-bracing can obstruct the view from the inside of tent.
- There is a need in the art for a tent structure that requires lithe or no assembly of the parts necessary for setting up the tent. There is also a need for the tent to be sturdy. Moreover, there is a need in the art for a tent that is adjustable to accommodate shrinking or expanding material. There is also a need for a tent that is quiet and that provides for unobstructed views from the inside of the tent.
- In one embodiment, a tent frame includes at least three support legs, the at least three support legs having a connected end and a free end, the at least three support legs comprising a collapsible truss including at least two compression members, a hinge situated between the compression members, and a tension member extending from a first point near the free end to a second point near the connected end, wherein the at least three support legs are joined at their respective connected ends. In another embodiment, the at least two compression members may include a roof pole and a wall pole. In another embodiment, the hinge may include a hinge pin and the hinge may be adapted to allow relative rotation of the roof pole and the wall pole about the hinge pin, the relative rotation limited to approximately 235 degrees. In still another embodiment, the frame may further include a compression hub wherein the at least three support legs are joined at their respective connected ends via a pivotal attachment between the roof pole and the compression hub. In yet another embodiment, the frame may further include a tension hub wherein the at least three support legs are joined at their respective connected ends via an additional attachment between the tension member and the tension hub. In yet another embodiment, the support legs may further include telescoping rods extendable from the sleeve end of their respective wall poles.
- In another embodiment, a tent frame includes at least three support legs, the support legs each including a means for collapsing the support leg and a means for stabilizing the support leg when in a set up position. The frame may further include a means for actuating the stabilizing means.
- In another embodiment, a method of setting up a tent includes providing a collapsible tent in the collapsed position, placing the collapsible tent on the ground thereby defining a center of the tent, unfolding at least three wall poles down about a first end from a generally vertical position to a generally horizontal position, each wall pole directed radially away from the center of the tent once unfolded, lifting at least three hinges diagonally upward away from the ground and outward away from the center of the tent, the hinge connected to an end of the wall pole near the center of the tent and connected to an end of a roof pole near the ground, wherein lifting the at least three hinges causes at least three support legs to be mostly formed, and tensioning at least three cables associated with the at least three support legs.
- In still another embodiment, a tent includes a collapsible frame and a shell adapted to cover the frame, the shell having at least one window opening and at least one window curtain covering the at least one window opening, the at least one window curtain being adapted to slidably open and close.
- While the present disclosure is directed toward a hunting tent, further areas of applicability will become apparent from the description provided herein. It should be understood that the description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
- The forgoing features, objects, and advantages of the invention will become apparent to those skilled in the art from the following detailed description, especially when considered in conjunction with the accompanying drawings in which like the numerals in the several views refer to corresponding parts.

FIG. 1 , one embodiment of atent 100 is shown. Thetent 100 may have aframe 102 providing for a fivesided tent 100. In a set up position, theframe 102 may converge toward the center and top of thetent 100 to form a roof. Thetent 100 may include ashell 104 adapted to cover theframe 102 and may includeopenings including vents 106,windows 108, anddoors 110. The following discussion will begin with a detailed discussion of theframe 102 and will move on to a detailed discussion of theshell 104. - Referring now to
FIG. 2 , theframe 102 may include a series of trusstype support legs 112 including compression members made up of aroof pole 114, awall pole 116, and atelescoping rod 118. Eachsupport leg 112 may also include a tension member in the form of acable 120 extending along the length of thesupport leg 112 along a path resembling, but offset from, the contour of thesupport leg 112. Thetelescoping rod 118 may telescope within thewall pole 116 and thewall pole 116 may be connected to theroof pole 114 with ahinge 122. Theroof pole 114 and thecable 120 may each converge atseparate hubs other roof poles 114 andcables 120, respectively, theother roof poles 114 andcables 120 being associated withother support legs 112 in the series ofsupport legs 112. Both theroof pole hub 124 and thecable hub 126 may be located near the top and near the center of theframe 102. Theroof pole hub 124 and thecable hub 126 may also be adjustable relative to each other to provide for adjusting tension in thecable 120 and in turn compression in thesupport leg 112. - Referring now to
FIG. 3 , theroof pole 114 may include a cylindricalhollow tube 128 with an inner diameter and an outer diameter. Theroof pole 114 may have ahub end 130 and ahinge end 132 defining alength 134. Theroof pole 114 may also have holes or a fixture on thehub end 130 and hingeend 132 for attachment to theroof pole hub 124 and thehinge 122, respectively. It is noted that theroof pole 114 may also be referred to as an upper pole as this is located closer to the top of theframe 102 in an expanded state. - Similarly, referring now to
FIG. 4 , thewall pole 116 may include a cylindricalhollow tube 136 with an inner diameter and an outer diameter. Thewall pole 116 may have ahinge end 133 and asleeve end 140 defining alength 142. Thewall pole 116 may also have holes or a fixture on thehinge end 133 andsleeve end 140 for attachment to thehinge 122 and thetelescoping rod 118, respectively. It is noted that thewall pole 116 may also be referred to as a lower pole as this is located closer to the bottom of theframe 102 in an expanded state. - Referring now to
FIG. 5 , thetelescoping rod 118 may include a cylindricalsolid shaft 144 with an outer diameter. Thetelescoping rod 118 may have asleeve end 146 and afree end 148 defining alength 150. Thesleeve end 146 may be adapted to sleeve within the inner diameter of thewall pole 116 and thefree end 148 may be adapted to connect with the bottom edge of thetent 100 and may be adapted to engage the ground. As shown inFIG. 6 , thefree end 148 may be covered with aboot 152 for protecting thetelescoping rod 118 and covering any sharp edges. Theboot 152 may be a rubber material adapted to grip surfaces it comes into contact with. Additionally, as shown inFIG. 7 , abushing 154 may be placed in thesleeve end 140 of thewall pole 116 for receiving thetelescoping rod 118. Thisbushing 154 may include a cylindrical shaft portion and a flange portion. The cylindrical shaft portion may be adapted for a snug fit within thewall pole 116 and the flange portion may be adapted to prevent thebushing 154 from fully traveling inside thewall pole 116. The cylindrical portion may be further adapted for sliding engagement with thetelescoping rod 118. - A discussion of the process of setting up the
frame 102 is necessary to further explain the detailed elements of theframe 102. Referring toFIG. 8 , a collapsed view of theframe 102 is shown. The figure shows thewall poles 116 in a vertical position defining an outer circle of thecollapsed frame 102. Thewall poles 116 are positioned with thehinge end 138 at the bottom and thesleeve end 140 at the top. The figure further shows theroof poles 114 in a vertical position defining an inner circle of the collapsed frame. Theroof poles 114 are positioned with thehub end 130 at the top and thehinge end 132 at the bottom. The figure also shows thetelescoping rods 118 with thesleeve end 146 telescoped inside thewall pole 116 and thefree end 148 projecting minimally out thesleeve end 140 of thewall pole 116 with aboot 152. Also shown is ahinge 122 between theroof pole 114 and thewall pole 116. Acable 120 is also shown extending from thecable hub 126 to a connection near thesleeve end 140 of thewall pole 116. Near the top of thecollapsed frame 102, as more clearly shown in the close-up view ofFIG. 9 , is acable hub 126 and aroof pole hub 124. As shown, theroof poles 114, defining the inner circle of poles, have a pivotal attachment to theroof pole hub 124 and thecables 120 are attached to thecable hub 126. -
FIG. 10 is a view of one embodiment where theframe 102 is in an initial stage of expansion in the set up process. As shown, thewall poles 116 have been rotated approximately 90 degrees relative to their initial vertical position and relative to the position of theroof poles 114. Thewall pole 116, in this embodiment, rotates about thehinge end 138 and the rotation relative to theroof pole 114 is accommodated by thehinge 122 between theroof pole 114 and thewall pole 116. -
FIG. 11 is a view of another stage of expansion of theframe 102. As shown, thehinge 122 between theroof pole 114 and thewall pole 116 has been moved from the base of thecollapsed frame 102 to a location upward and outward from the base and in the plane defined by the associatedwall pole 116 androof pole 114 in the previous position. This movement has caused thewall pole 116 to rotate about itssleeve end 140 an additional 65 to 85 degrees, approximately, relative to its previous position. The movement of thehinge 122 has also caused theroof pole 114 to rotate about itshub end 130 approximately 60 to 80 degrees relative to its previous vertical position. Thus, the rotation of theroof pole 114 andwall pole 116 relative to each other may be from approximately 210 degrees to approximately 260 degrees. In one embodiment, this relative rotation is approximately 235 degrees. InFIG. 12 , twoadditional support legs 112 are expanded by moving thehinge 122 from the base of thecollapsed frame 102 to a position outward and upward from the base position. InFIG. 13 , all fivesupport legs 112 have been expanded. At this point, as will be described in more detail later in the specification, thecrank assembly 156 at the top of theframe 102 may be used to provide an initial amount of tension in thecables 120 to secure the shape of theframe 102. - Referring now to
FIG. 14 , three of thetelescoping rods 118 have been extended out of thesleeve end 140 of their associatedwall poles 116 and have been secured in position with aspring ball 158. Also shown inFIG. 14 is acrank assembly 156 for tensioning thecables 120. InFIG. 15 , theframe 102 is fully expanded and in a set up position. In this position, thecrank assembly 156 may be rotated to raise thecable hub 126 relative to theroof pole hub 124 causing tension in thecables 120 of eachsupport leg 112 simultaneously. In the present embodiment, theshell 104 of thetent 100 rests against the outer face of thiscable 120 on each of thesupport legs 112. Thus, extending thecable hub 126 upward may tighten the roof portion of the shell 104 (not shown) as well as the wall portion. This may also stiffen theframe 102. It is noted that the circumferential ring shown at the base of the frame is in place only as a lateral restraint in the absence of ashell 104. In use as shown later, theframe 102 may be expanded with theshell 104 in place and this circumferential ring is not necessary. -
FIG. 16 shows a more detailed view of an expandedsupport leg 112 of aframe 102. The figure shows a crankassembly 156, aroof pole hub 124, acable hub 126, aroof pole 114, ahinge 122, awall pole 116, andtelescoping rod 118, and acable 120. The details of the interactions of each of these elements will now be described in further detail. -
FIG. 17 shows a close-up side and top view of a top of an expandedframe 102 according to certain embodiments. The figure shows aroof pole hub 124 with fiveroof poles 114 pivotally attached to it. The figure also shows acable hub 126 with fivecables 120 attached to it, thecables 120 corresponding to theroof poles 114. Additionally shown is acrank assembly 156 extending through theroof pole hub 124 and up to thecable hub 126. Theroof pole hub 124 may be referred to as a compression hub as it is adapted to resist the radial compressive forces of themultiple roof poles 114 leaning in upon the hub. In contrast, thecable hub 126 may be referred to as a tension hub as it is adapted to resist the radial tension forces of themultiple cables 120 pulling radially outward upon the hub. - In further reference to
FIG. 17 , thecrank assembly 156 shown includes aknob 160, ahandle 162, and a threadedrod 164. Theknob 160 may include a spherical shaped object with a bore for receiving thehandle 162. In the present embodiment, thehandle 162 includes abent rod 166 with aknob end 168 and a threadedrod end 170. At theknob end 168, thehandle 162 includes threads for receiving anut 170, preferably a lock nut. Theknob end 168 may be inserted through the bore of theknob 160 and theknob 160 may be secured on thehandle 162 with thenut 170. The bore may be sized for a loose fit to allow theknob 160 to freely rotate on thehandle 162. At the threadedrod end 170 of thehandle 162, thehandle 162 may include aU-shaped plate 172 for receiving the threadedrod 164. TheU-shaped plate 172 may include holes aligned with a transverse bore through the threadedrod 164. TheU-shaped plate 172 may be attached to the threadedrod 164 with a bolt 174 and a nut 176. The connection may prevent relative rotation between thehandle 162 and the threadedrod 164, but may allow for a pivoting motion relative to each other. That is, theU-shaped plate 172 connection may allow a longitudinal axis of each to rotate relative to one another about the axis of the bolt 174. However, the longitudinal axis of each is not free to rotate relative to the longitudinal axis of the other. Thus, when thehandle 162 is rotated, the threadedrod 164 rotates accordingly. - In the present embodiment, the
roof pole hub 124 includes a threaded bore through its center for receiving the threadedrod 164. The threadedrod 164, as discussed, is connected to thehandle 162 at one end. The threadedrod 164 then passes through the threaded bore of theroof pole hub 124 and connects to thecable hub 126. Thus, as thecrank assembly 156 is rotated clockwise (e.g. when viewed from the bottom as one would if they were inside the tent looking upward at the crank assembly), the threadedrod 164 travels upward through theroof pole hub 124 causing thecable hub 126 to extend upward relative to theroof pole hub 124. - Continuing the reference to
FIG. 17 , the pivotal attachment between theroof poles 114 and theroof pole hub 124 may include aplate 125 positioned vertically and protruding from theroof pole hub 124. Theplate 125 may be received by theroof pole 114 in a slot and a through bolt may be provided through theroof pole 114 and theplate 125. Additionally, thecables 120 for eachsupport leg 112 may include a loop and may be attached to thecable hub 126 with a rivet, bolt, or other attachment known in the art for attachingcable 120 with connection loops. As shown, the cable loop is formed by folding thecable 120 onto itself and attaching it to itself with a crimp. Alternatively, a wire rope clip or other connections known in the art could be used. - Referring now to
FIG. 18 , a collapsed view of ahinge 122 is shown. Thehinge 122 may include aroof pole portion 178 and awall pole portion 180 as well as acable extension arm 182. As shown, theroof pole portion 178 and thewall pole portion 180 include atubular portion roof pole portion 178 may further include asolid bar portion 188 extending diagonally from thetubular portion 184. Thewall pole portion 180 may further include a pair of bars orplates 190 also extending diagonally from thetubular portion 186 and spaced to sandwich thesolid bar portion 188 of theroof pole portion 178 between them. Thesolid bar 188 and the pair ofplates 190 may be connected with ahinge pin 192 near their ends opposite their attachment to their respectivetubular portions hinge pin 192 to be in a double shear condition providing for a relatively strong connection as opposed to a single shear condition. Thehinge pin 192 may be a bolt or may be some other pin known in the art. Thetubular portion 184 of theroof pole portion 178 and thetubular portion 186 ofwall pole portion 180 of thehinge 122 may be anchored in each of therespective poles tubular portion solid bar 188 or pair ofplates 190 may be a welded connection as shown, or may be any rigid connection known in the art. - Still referring to
FIG. 18 , thecable extension arm 182 may be adapted to saddle around thehinge 122. Thecable extension arm 182 may also have a slotted hole and may be attached to thehinge 122 with thehinge pin 192 passing through the slotted hole. In addition, thecable extension arm 182 may include a rigidly attachedpin 194 passing across its saddle portion. Thecable extension arm 182 may also be adapted to receive thecable 120. Thecable 120 may enter thecable extension arm 182 at the outer most edge opposite that of the slotted hole. Thecable 120 may be received in thecable extension arm 182 and thecable 120 may have a steel ball stop permanently pressed over it. Thecable extension arm 182 may include a cable bushing to receive the steel ball preventing the cable from sliding in or out of thecable extension arm 182. Thecable extension arm 182 may also have a male portion of asnap 196 on one side or each side for button attachment of a strap from theshell portion 104 of thetent 100. Thesnap 196 may include a screw or bolt which in turn also anchors the cable bushing within thecable extension arm 182. - Referring now to
FIGS. 19 and 20 , a partially expanded view of ahinge 122 is shown. In comparing theFIGS. 19 and 20 toFIG. 18 , it can be seen that theroof pole portion 178 andwall pole portion 180 of thehinge 122 may allow theroof pole 114 and thewall pole 116 to rotate about thehinge pin 192 relative to each other within a certain range. That is, starting from the collapsed position shown inFIG. 18 , theroof pole 114 and thewall pole 116 may be substantially parallel. As the frame is expanded, theroof pole 114 and thewall pole 116 may be free to rotate until they reach the position shown inFIG. 21 , reflecting a range of approximately 210 degrees to approximately 260 degrees. In one embodiment, theroof pole 114 and thewall pole 116 may be rotated approximately 235 degrees relative to each other. When the position ofFIG. 21 is reached, thetubular portion 186 of thewall pole portion 180 of thehinge 122 may abut against the side of theroof pole portion 178 preventing further rotation and the included interior angle between theroof pole 114 and thewall pole 116 may be from approximately 110 degrees to approximately 140 degrees. In one embodiment, the included interior angle may be approximately 125 degrees. - Referring now to
FIG. 22 , the position and effect of thecable extension arm 182 may be seen. The toe end of theroof pole portion 178 of thehinge 122 may include aconcave receiving portion 198 adapted to receive the rigidly attachedpin 194 of thecable extension arm 182. Additionally, the slotted hole in thecable extension arm 182 allows thecable extension arm 182 to slide inward and outward allowing the rigidly attachedpin 194 to pass beyond the outer tip of theconcave receiving portion 198. When thecrank assembly 156 at the top of theframe 102 is used to tension thecables 120, those of skill in the art will understand and appreciate that thecable extension arm 182 will be forced inward, causing thecable extension arm 192 to slide along thehinge pin 192 via its slotted hole, thus engaging the rigidly attachedpin 194 of thecable extension arm 182 in theconcave receiving portion 198 of theroof pole portion 178 of thehinge 122. Once positioned, the rigidly attachedpin 194 seated in theconcave receiving portion 198 acts to prevent thecable extension arm 182 from rotating out of position under the compressive force of thecable 120 passing across it. That is, once in position with tension on thecable 120, one way to fold thecable extension arm 182 back, as shown inFIG. 22 , is to release the cable tension, which a user would not likely do unless they were intending on collapsing thetent 100. Alternatively, thewall pole 116 could be folded upward to cause thewall pole portion 180 of thehinge 122 to push on and force the rigidly attachedpin 194 from its seat in theconcave receiving portion 198. However, when theshell 104 of thetent 100 is in place, a circumferential barrier to this type of motion is provided and folding thewall pole 116 in this manner is not feasible. - As shown more clearly in
FIG. 23 , thecable 120 may extend down the length of thewall pole 116 and be secured to thesleeve end 140 of thewall pole 116 with a loop connection similar to that included at thecable hub 126 at the top of theframe 102. Here, however, the loop may pass through a loopedplate 200 which is secured with a bolt inserted into a threaded hole in thewall pole 116. - In further reference to the stability of the
cable extension arm 182, the length of thecable 120 between the attachment of thecable 120 to thesleeve end 140 of thewall pole 116 and the secured attachment to thecable extension arm 182 defines a predetermined distance. Thus, when theframe 102 is expanded, the predetermined length of thecable 120 between thesleeve end 140 of thewall pole 116 and thecable extension arm 182 naturally causes thecable extension arm 182 to be positioned as shown inFIG. 21 and prevents thecable extension arm 182 from rotating up past theconcave receiving portion 198. - Referring back to
FIG. 23 , aspring ball 202 is shown projecting through a hole in thewall pole 116. Thespring ball 202 is positioned on thetelescoping rod 118 such that when thetelescoping rod 118 is extended out of the end of thewall pole 116, thespring ball 202 snaps into place in the hole shown preventing additional outward movement of thetelescoping rod 118 and also preventing inward movement of thetelescoping rod 118. Information regarding an alternative spring ball embodiment, may be found inFIG. 77 or 78. - It is noted here that the truss action of the embodiment described may be very efficient. As shown in
FIG. 24 , asupport leg 112 system without atension cable 120 is shown. When such asupport leg 112 is loaded from above, the geometry of thesupport leg 112 may cause thehinge 122 to tend toward collapsing. However, as discussed with respect toFIGS. 19 and 20 , the geometry of thehinge 122 may prevent relative rotation in that direction and thus may act as a rigid connection between theroof pole 114 and thewall pole 116. As such, no relative rotation may be allowed between theroof pole 114 and thewall pole 116 and thesupport leg 112 may act as a continuous member with a bent shape. Thus, the deflected shape shown inFIG. 24 may result (exaggerated for purposes of explanation). - When a truss system is applied to the same leg system, a strut in the form of a
cable extension arm 182 or other member may create a lateral force to the hinge location due to the tension in thecable 120 passing over the strut. As shown, this lateral force may induce a bending moment in theframe 102 opposite that caused by loading the structure. As such, the effect of the truss system may be to cause a deflected shape as shown inFIG. 25 (exaggerated for purposes of explanation). - The net result may be a truss system with internal forces that are opposite to that of loading the structure. Thus, when loaded, the deflected shapes of
FIGS. 24 and 25 may counteract each other to create aframe 102 with compression members showing little or no bending deflection, the compression members being theroof poles 114 andwall poles 116 and the tension member being thecable 120. As such, the capacity and strength of theframe 102 may become more dependent on the compressive strength of the wall androof poles cable 120 rather than the bending strength of the tall slender poles, 114,116. This may create a much stronger system than if the truss system were omitted. - Referring to
FIG. 26 , atent 100 with ashell 104 is shown according to certain embodiments. Thetent 100 and associatedshell 104 may havewalls 204 and an associatedroof 206. Theshell 104 of thetent 100 may or may not have a bottom 208. Alternatively, it may simply have apartial bottom 208 around the perimeter of the tent. Thetent shell 104 may be adapted to fit over aframe 102 similar to that previously described. As such, theshell 104 of thetent 100 may be adapted to rest on thecables 120 of theframe 102 as thecables 120 define the outer most portions of theframe 102. - As shown in
FIG. 26 , thetent 100 may havewindow openings 210 in any or all of thewalls 204. Thewindows 210 may extend substantially all the way across theshell wall 204 and may be located in the upper half of the wall height. Thewindow openings 210 may include awindow screen 212 and a window curtain 214 (not shown). Additionally, theshell 104 of thetent 100 may include peep holes 216 (shown closed) for viewing outside of thetent 100 when awindow curtain 214 in a particular direction may not be open. Theshell 104 of thetent 100 may be made from a variety of material including but not limited to canvas, vinyl, or other textiles known to resist wind, rain, and other natural elements. Theshell 104 may be camouflage and the window screens 212 may also be camouflage while thewindow curtain 214 may be a solid color creating a background for the screen camouflage. Alternatively, thescreens 212 may be a regular screen color and thewindow curtain 214 may be camouflage. Alternatively, both thewindow screen 212 and thewindow curtain 214 may be camouflage. In still another embodiment, thewindow curtains 214 may be clear see through vinyl. Connections to and from theshell 104 may take several forms and may include sewed connections, glued or adhered connections. Connections may also take the form of a hole in theshell 104 reinforced with a grommet. Other connections will be apparent to those skilled in the art. - Referring now to
FIGS. 27-30 , a verticallyslidable window curtain 214 is shown. Thewindow curtain 214 may be made of the same or similar material as theshell 104. Thetent shell 104 may haveshell channels 216 affixed to the edges of thewindow openings 210 for receiving the acorresponding curtain channel 218 affixed to the vertical edges of thewindow curtains 214. The window curtain may also havepull tabs 220 in each of the corners of thewindow curtain 214 for sliding thewindow curtain 214 up and down. - As can be seen in
FIGS. 28 and 29 , thepull tabs 220 in the bottom corners of thewindow curtain 214 may be pulled on to slide thewindow curtain 214 downward causing thewindow opening 210 to be exposed above thecurtain 214 and also causing thewindow curtain 214 to lap along the inside face of theshell 104 below thewindow opening 210.FIG. 28 shows thewindow curtain 214 pulled partially open andFIG. 29 shows thewindow curtain 214 pulled fully open. To prevent the window curtain from continuing to slide downward or to provide a stopping point for thewindow curtain 214, arope 222 may be fastened to thetent 100 and further fastened to arope knob 224 in the upper corners of thewindow curtain 214 as shown inFIG. 30 . Therope 222 may have a length and may be fastened to thetent 100 in a location so as to prevent thewindow curtain 214 from moving downward beyond the length of theshell channel 216. Referring back toFIG. 29 , thecurtain channel 218 and theshell channel 216 may maintain an overlap of approximately an inch or more. In another embodiment, theshell channel 216 extends 12″ to 18″ down beyond the bottom of thewindow opening 210. In this embodiment, therope 222 andrope knob 224 may not be necessary as the overlap of thecurtain channel 218 maintains sufficient overlap with theshell channel 216 to avoid falling out the bottom of theshell channel 216. This maintains thewindow curtain 214 closer to the inside face of theshell 104 and prevents excess flapping and noise. As can be seen inFIG. 31 , the vertical slidingwindow curtain 214 may also be slid upward by grasping thepull tabs 220 in the upper corners of thewindow curtain 214 and pulling up on thewindow curtain 214. - For a detailed discussion of the
shell channel 216 and thecurtain channel 218, reference is now made toFIG. 32A .FIG. 32A is a cross section view of a shell andcurtain channel shell channel 216 and thecurtain channel 218 may be identical reversible pieces to cut down on manufacturing costs. Alternatively, they may not be identical. Thechannels window curtain 214 from sliding inadvertently but sufficient looseness to allow thewindow curtain 214 to slide readily when thepull tabs 220 are pulled on. As shown inFIG. 32A , thechannels tab portion 226 for sewing or otherwise adhering to thetent shell 104 or thewindow curtain 214. Thechannels portion 228 including afemale receiving portion 230 and amale portion 232 adapted to allow relative longitudinal movement between the twochannels FIG. 32B , one of thechannels female receiving portion 230 and the other channel has only amale portion 232 allowing the twochannels - Referring now to
FIG. 33A , an exterior view of atent 100 is shown. As can be seen from theFIG. 33A , thescreens 212 are camouflage screens and are removable. Thescreens 212 may be attached to the window opening in a similar manner to that of awindow curtain 214. That is, thescreen 212 may have a screen channel 236 sewn to its edge similar to that shown inFIG. 32A and theshell 104 may have a corresponding shell channel 234 sewn to the edge of thewindow opening 210 similar toFIG. 32A . As such, thescreen 212 may slide up and down in a similar fashion as thewindow curtain 214. As shown inFIG. 33B , thewindow channels window curtain 214 and thescreen 212 separately or together. Alternatively, the channel affixed to theshell 104 may simply have two sets of channels: one for receiving thewindow curtain 214 and one for receiving thescreen 212. Alternatively, thescreens 212 may be secured with hook and loop and may be removed prior to beginning hunting, photography, or some other activity where quiet removal is required. In another embodiment shown inFIG. 91 , an alternative geometry of the channels described is shown. This geometry could be used as a shell channel 416, 434 or a window curtain/screen channel 418, 436. - Referring now to
FIGS. 34 and 35 , the tent shell may include collapsible/expandable peek/vent holes 216 for viewing outside thetent 100 or allowing air to flow in and out of thetent 100 when thewindow curtains 214 are closed. As shown, the peek holes 216 may be near the seam between thewall portion 204 and theroof portion 206 of theshell 104 and may be located toward the middle of the width of thewall 204. As additionally shown inFIG. 34 , afabric sleeve 238 may be sewn to the inside face of the shell just below thepeek hole 216 opening. Aholder 240 with a bottom portion, an upper portion, and a plastic hinge may be positioned within thesleeve 238 and may extend up and out of thesleeve 238 such that the hinge portion of theholder 240 is located approximately at the top of thesleeve 238 and the upper portion extends beyond thesleeve 238. The plastic hinge may allow the upper portion to lie substantially flat against the underside of theroof 206. - Referring now to
FIG. 35 , to open thepeek hole 216, the upper portion of theholder 240 may be forced outward and upward causing the hinge of theholder 240 to allow the upper portion to rotate approximately 115 degrees relative to the lower portion of theholder 240 causing a V-shapedholder 240 directed into the interior of thetent 100. Thepeek hole 216 may take the shape of a diamond and may have a camouflage screen permanently sewn in. The upper most end of theholder 240 may secure itself in the seam between the screen of thepeek hole 216 and its attachment to theroof portion 206 of theshell 104. Thepeek hole 216 may be approximately 16″ wide by 4″ high. Alternatively it may be larger or smaller. - Referring back to
FIG. 1 , the peek holes 216 are shown from the outside of thetent 100. It is noted here that the shape of thepeek hole 216 and the nature of its support cause it to create an eave on theroof portion 206 of theshell 104 and also cause the screen of thepeek hole 216 to be tilted downward below the eave and the portion of theshell 104 below thepeek hole 216 to be tilted inward and upward. This allows the eave shape of theroof 206 to protect thepeek hole 216 from water entry. Also, the downward directed screen helps prevent water entry and the upward facing portion of theshell 104 below the screen allows for water to run-off away from the opening. - Referring ahead to
FIG. 45 , the tent may also include adoor 242 in the form of a vertical openable seam extending from near the bottom of atent wall 204 to near the top of atent wall 204. The seam may also travel laterally across thewall 204 near the top or bottom of the seam or both. The seam may be a secureable seam with hook and loop, a zipper, or other known securing devices. In the case of a zipper, the zipper may be similar to a ziploc baggie with a slidable element that forces a longitudinal male and female element together, thereby providing a relatively quiet process of closing and opening. - The use and set up of the
tent 100 will now be described with respect toFIGS. 36-51 . The shell described above may be positioned over theframe 102 and theframe 102 may be in a collapsed position for portability. Thecollapsed frame 102 andshell 104 may be placed in a bag to form a backpack for even more portability as shown inFIG. 36 . This backpack assembly with thecollapsed tent 100 included may range from approximately 5 lbs to 30 lbs depending on the size of thetent 100 and the materials used. The size of thecollapsed tent 100 may range from approximately 4″ in diameter to approximately 18″ in diameter and have a length ranging from approximately 24″ long to approximately 50″ long. - In
FIG. 37 , thecollapsed tent 100 has been removed from the back of the wearer and has been placed on the ground and initial preparations are made. InFIG. 38 , the first of fivewall poles 116 are being folded down in the same way as that shown inFIG. 10 . InFIG. 39 ,additional wall poles 116 are folded down until allwall poles 116 are folded down as shown inFIG. 40 . The next step, as shown inFIG. 41 , may include grasping one of theroof poles 114 and pulling it upward to a position similar to that shown inFIG. 11 .FIG. 42 showsadditional roof poles 114 being pulled upward into position until allroof poles 114 are pulled into position as shown inFIG. 43 . At this point, all of thewall poles 116 androof poles 114 have traveled to their final relative position. Also, thecable extension arm 182 may not yet be seated in theconcave receiving portion 198 of theroof pole portion 178 of thehinge 122 as discussed with respect toFIG. 22 . However, at this point, an initial amount of tension may be applied to thecables 120 by turning thecrank assembly 156 and stabilizing theframe 102 for the remaining steps of set up. This initial tension will begin to engage thecable extension arm 182 in theconcave receiving potion 198.FIG. 44 shows the user having entered thetent 100 and extending thefirst telescoping rod 118 from the bottom of itswall pole 116 similar to that shown inFIG. 14 . InFIG. 45 , the remainingtelescoping rods 118 have been extended. It is noted that at this point, theshell 104 of thetent 100 is positioned over theframe 102 but is relatively loosely positioned.FIG. 46 shows thetent 100 after thecrank assembly 156 has been turned causing thecable hub 126 to raise relative to theroof pole hub 124 and create tension in thecables 120 and thus drawing theshell 104 of thetent 100 taut. This is caused by the cable tension causing theframe 102 to extend upward and outward.FIGS. 47-51 show the fully set uptent 100 from various angles and in various positions. InFIG. 48 , apartial bottom 208 is shown around the perimeter of thetent 100. Alternatively, afull bottom 208 may be provided. The take down procedure may follow the steps above in the opposite order and variations will be apparent to those skilled in the art. - Those skilled in the art will understand and appreciate that several alternatives are available to the specific embodiments described above. These alternatives are still within the scope of the invention.
- For example, the elements of the
frame 102 may be constructed of most any material, including but not limited to steel, aluminum, various plastics, or other materials known in the art. For example, thepole members frame 102 may be constructed of at least threesupport legs 112 and any number ofadditional support legs 112. Alternatively, theframe 102 may be as few as one or two support legs where external support is provided. - As shown in
FIG. 52 , rather than telescopingrods 118,rods 318 may have a hinged attachment to thewall pole 116 and thus may have a collapsed position as shown. As therods 318 are rotated about the hinged connection to a straight position generally parallel with thewall pole 116, as shown inFIG. 53 , thetent frame 102 will rise in a similar manner as though atelescoping rod 118 had been extended. As shown inFIG. 54 , a hinge pin may be offset to cause the bottom end of thewall pole 116 to abut the top end of therod 318 when therod 318 is moved to its expanded position. As such, therod 318 is prevented from over rotating. Moreover, as shown, thecable 120 may be secured to the outer surface of therod 318. Thus, when thecables 120 are tensioned with thecrank assembly 156, the tension from thecable 120 will hold therod 318 in an expanded position preventing therod 318 from collapsing. - Another alternative embodiment is shown in
FIGS. 55-59 . In this embodiment, as shown inFIG. 55 , thecable 120 does not extend to thesleeve end 140 of thewall pole 116. Instead, thecable 120 stops near thehinge end 132 of theroof pole 114. Additionally, theroof pole 114 does not extend all the way to thehinge 122. Instead, afiberglass extension pole 314 may be connected to the lower end of theroof pole 114. Alternatively, thefiberglass extension pole 314 could be connected to the top of thewall pole 116. In this embodiment, the hoop tension provided by theshell 104 of thetent 100 holds thewall poles 116 in while thecable 120 pulls up on theroof poles 114. The connection between theroof poles 114 and thewall poles 116 is flexible thereby creating an outward force on the top of thewall pole 116 in opposition to the hoop tension in theshell 104 causing theshell 104 to be drawn reasonably taut.FIG. 56 is similar toFIG. 55 , but includes ashell 104 draped over theframe 102.FIG. 57 shows theframe 102 fully expanded andFIG. 58 shows theframe 102 fully expanded with ashell 104 in place.FIG. 59 is a close up view of thecable 120,roof pole 114,fiberglass extension pole 314, andwall pole 116 of the embodiment shown inFIG. 55 . Also shown is a hinged connection between thefiberglass extension pole 314 and the top of thewall pole 116. - In another embodiment, as shown in
FIG. 60 , ahinge 322 between aroof pole 114 and awall pole 116 is shown. In this embodiment a separatecable extension arm 182 is not included, but is instead incorporated into thewall pole portion 380 of thehinge 322. Thus, since thecable extension arm 182 is not free to rotate, thecable 120 does not need to provide it with stability by having a bushing that receives a steel ball. Instead, afree spinning pulley 382 is shown. It is noted that this may limit the amount of outward pushing force that can be generated by tensioning thecable 120 because the distance between thecable 120 and thehinge 322 is not as large. The leg of thehinge 322 supporting thepulley 382 could be extended inFIG. 60 , however, because of its rigid nature relative to thewall pole portion 380 of thehinge 322, this would cause thecollapsed frame 102 to occupy a larger volume. - In another embodiment shown in
FIG. 61 , aroof pole hub 324 and crankassembly 356 are shown that allow for more quickly tensioning thecables 120. That is, theroof pole hub 324 is not threaded and thus provides for slidable motion of the threadedrod 164 of thecrank assembly 356. Once theframe 102 is set up and thecables 120 need to be tensioned, the user may be able to simply press upward on thecrank assembly 356 to create tension in thecables 120. Then, to secure the threadedrod 164 in the upward position and provide for further tightening of thecables 120, a threadedgear 360 may be engaged. The threadedgear 360 may be hinged and anchored by a spring as shown so as to pivot out of the way when the threadedrod 164 is advanced upward, but to maintain contact with the threadedrod 164 as shown inFIG. 61 . Thereafter, as shown inFIG. 62 , turning the threadedrod 164 will cause the threads of the threadedgear 360 to engage the threads of the threadedrod 164 and draw the threadedgear 360 down against the top of theroof pole hub 324. The threadedrod 164 can then be further advanced by turning it. In addition, the threadedrod 164 is prevented from withdrawing from theroof pole hub 324 by the threadedgear 360. In an alternative embodiment, the engagement of the threads on the threadedrod 164 with threads on the interior of theroof pole hub 124 may be selectively controlled with a lever which moves a clamping threaded gear 560 into and out of position. This may be similar to that found on a typical work piece clamp on a chop saw. - It is noted here that alternatives to a crank
assembly cable 120 could take the form of a rope, wire, strap, rod, or other tension member known in the art. - For purposes of minimizing weight and thus maximizing portability, several of the elements of the
tent 100 may be made from plastic, aluminum, magnesium, or other suitable light weight materials. The following figures show elements adapted to be made from plastic. Those skilled in the art will understand and appreciate that several other elements of thetent 100, not further described below, may also be made from plastic or other light weight materials. -
FIGS. 63 and 64 show acable hub 326 according to one embodiment. Thecables 120 shown include looped ends as before. As such, thecable hub 326 includes upward projectingcylindrical portions 327 that receive the loops of thecables 120. Additionally, the surface of thecable hub 326 adjacent to thecylindrical portions 327 may be sloped to approximate the slope of thecables 120 as they travel toward thehinge 122 of thesupport leg 112. A portion of the top surface of the cylindrical portion may also be sloped to facilitate easier attachment of the cables. The top of thehub 326, however, may be flat to accommodate a washer and a nut placed over the top of thehub 326 to secure thecables 120 in place and prevent them from slipping off the top of thecylindrical portions 327. The washer and nut may be secured via a threaded stud embedded in the cable hub. Alternatively, the threaded stud may pass through an internal vertical bore and be prevented from rotating when the top washer and nut are tightened by an opposing nut received into a recess on the bottom of thehub 326. In both instances described, the threaded stud may have a blanked portion (e.g. no threads) extending downward from thecable hub 326 to the threadedrod 364. -
FIGS. 65 and 66 show aroof pole hub 524 according to another embodiment. As shown, theroof pole hub 524 is adapted to receiveroof poles 514 from several sides. Thehub 524 includes a block out location for eachroof pole 514 to nest in the side of thehub 524. Adjacent to each block out and on either side of each block out is a an additional block out to receive a transverse pin 525 (shown inFIG. 67 ) positioned through the end of theroof pole 514. Also shown is a washer anchored with a screw from the top of thehub 524 and positioned to extend over the top of two adjacenttransverse pins 525 to secure them in their block out positions. Theroof pole hub 524 may include a threaded bore to threadably engage the threadedrod 164 from the crank assembly. -
FIGS. 68-70 show a crankassembly 356 according to another embodiment.FIG. 68 shows a threadedrod 364 for receiving acable hub 326 on one end and a crank assembly handle 362 on a stepped end. The threadedrod 364 may have a vertical bore in the top of the threadedrod 364 for receiving the blanked portion of the stud from thecable hub 326. Thus, the threadedrod 364 may be free to rotate freely relative to thecable hub 326, but also provide vertical upward force on thecable hub 326. The stepped end of the threadedrod 364 may have a horizontal hole for receiving a bolt or pin from thehandle 362.FIG. 69 shows a crank assembly handle 362 according to another embodiment with a stepped portion for receiving aknob 360 and a saddle type end to receive the bottom of the threadedrod 364. The crank assembly handle 362 also includes a bore for receiving a pin or bolt to secure thehandle 362 to the threadedrod 364. Thehandle 362 also includes a bend for accommodating overhead cranking of thehandle 362.FIG. 70 shows another embodiment of aknob 360 with a bore adapted to loosely receive the smaller diameter portion of thehandle 362 so as to freely spin. -
FIGS. 71-75 show another embodiment of ahinge 522 between aroof pole 314 and awall pole 316. Theroof pole portion 578 and thewall pole portion 580 include atubular portion roof pole portion 578 of thehinge 522 may further include asolid bar portion 588 extending substantially orthogonally to thetubular portion 584. Thewall pole portion 580 may further include a pair of tabs orplates 590 also extending substantially orthogonally from thetubular portion 586 and spaced to sandwich thesolid bar portion 580 of theroof pole portion 578 between them. Thesolid bar 588 and the pair ofplates 590 may be connected with a hinge pin 592 near the end of theplates 590 of thewall pole portion 580 and near the base of thesolid bar portion 588 of theroof pole portion 578. The upper surface of thewall pole portion 580 may be concave for receiving and nesting tightly against the bottom surface of theroof pole portion 578 and preventing further rotation once expanded. The outer surface of theroof pole portion 578 also may include arecess 525 adapted to receive acable stop 523. As shown inFIG. 72 , thecable 520 includes a loop at each end for attachment to thecable hub 326 at one end and an anchor point at the other. As also shown, thecable 520 may include acable stop 523 in position to fit into therecess 525 of theroof pole portion 578 shown inFIG. 71 . Offset from the hinge pin 592, theroof pole portion 578 may also include anub 527 on each side of thesolid bar portion 588 for receiving a cable guide swivel 529 (not shown). For more information regarding a cable guide swivel see FIGS. 76 and 82-85. - Further details of the
roof pole portion 578 and thewall pole portion 580 are shown inFIGS. 73-75 .FIG. 73 shows a butt end inside view of aroof pole portion 578 showing thetubular portion 584 and thesolid bar portion 588 extending substantially orthogonally thereto with a concave slot for receiving thecable 520 and anub 527 on each side for receiving acable guide swivel 529.FIG. 74 shows a top view of theroof pole portion 578.FIG. 75 shows a butt end view of awall pole portion 580 showing atubular portion 584 and a pair of tabs orplates 590 extending substantially orthogonally thereto. -
FIG. 76 shows two views of acable guide swivel 529. Thecable guide swivel 529 may be attached to thenubs 527 of thesolid bar portion 588 of theroof pole portion 578 of thehinge 522. The U-shapedcable guide swivel 529 may straddle thesolid bar portion 588 and remain slightly offset from the surface of thesolid bar portion 588, allowing thecable 520 to pass there through and allowing thecable guide swivel 529 to pivot about thenubs 527. Thecable guide swivel 529 may also include a threadedstud 531 extending away from thehinge 522 for extension through a grommet on theshell 104 of thetent 100 acting as a support point for theshell 104 and allowing theshell 104 to be secured to theframe 102. -
FIG. 77 shows an alternative embodiment of the attachment of thecable 120 to thesleeve end 140 of thewall pole 116. The cable loop is looped around thewall pole 116 and also around acable anchor 517. Thecable anchor 517 includes a raisedprotrusion 519 on an upper end, the raisedprotrusion 519 having a contour similar to that of an angled cable loop. Thecable anchor 517 has a concave underside and is mounted on thewall pole 116 with two fasteners passing through thecable anchor 517 and into threaded bores in thewall pole 116. Alternatively the bores may not be threaded and the fasteners may be rivets. Thecable anchor 517 also includes a tunnel likestructure 521 for securing aspring ball 502. Thespring ball 502 may be positioned within thetunnel 521 so as to force theball portion 503 of thespring ball 502 against the surface of thewall pole 116. Theball portion 503 of thespring ball 502 may be positioned outside a bore through thewall pole 116. As such, when thetelescoping rod 118 is in place in thewall pole 116, thespring ball 502 is prevented from fully entering the bore. However, when thetelescoping rod 118 is extended, theball portion 503 of thespring ball 502 may fully enter thewall pole 116 and as such, may prevent thetelescoping rod 118 from re-entering thewall pole 116. In order to retract thetelescoping rod 118, a ring may be placed under the arm of thespring ball 502 to allow theball portion 503 to be pulled from the bore and allow thetelescoping rod 118 to be retracted. The elements of the connection are more clearly shown individually inFIG. 78 . - Still another alternative for the
hinge 722 is shown inFIG. 79 . In this embodiment, thewall pole portion 780 may extend diagonally from the top of thewall pole 716 and may straddle theroof pole 714. Thewall pole portion 780 may be connected to theroof pole 714 with ahinge pin 792. Thewall pole portion 780 may also include a concave surface for nesting against the bottom surface of theroof pole 714 and preventing full rotation of the roof andwall pole frame 102. Theroof pole 714 may extend beyond thehinge pin 792 and have aslot 779 for receiving atooth 781 of thecable extension arm 782. Thecable extension arm 782 may pivot about a pin located near the diagonal transition between thewall pole 716 and thewall pole portion 780 of thehinge 722. Thecable extension arm 782 may extend upward and outward and may have atooth 781 for engaging theslot 779 on the end of theroof pole 714. In the present embodiment, thecable extension arm 782 may also include arecess 725 for acable stop 723. Once in position, and thecable 720 is tensioned, thecable stop 723 will maintain an upward force on thecable extension arm 782 and maintain thetooth 781 of thecable extension arm 782 in theslot 779 of theroof pole 714. As such, as long as there is tension on thecable 720, thehinge 722 remains in a fixed position. Still another embodiment of ahinge 1122 is shown inFIG. 90 . Thishinge 1122 is similar to thehinge 722 in that the roof pole 1114 may extend beyond thehinge pin 1192. However, rather than having a slot for receiving a tooth, the roof pole 1114 extends to thecable 1120 and has arecess 1125 for acable stop 1123. - In still another embodiment, as shown in
FIG. 80 , asupport leg 112 is shown with anadditional hinge 244 for tensioning of thecables 120, and to shorten the length of the tent in its final collapsed position. As shown, theroof pole 114 has ahinge 244 at approximately its midpoint. As such, if thecable 120 is fixed at each end prior to setting up thetent 100, thehinge 244 in theroof pole 114 may be the final step in setting up thetent 100 and may create tension in thecable 120. Also shown is the collapsed configuration of atent 100 with such aroof pole hinge 244. It is noted here that several alternatives to a crankassembly 156 may be used to create tension in thecable 120. These alternatives may include a leverage handle for extending thecable extension arm 182 to tension thecables 120 or include a threadedextension arm 182 that can be extended outward to tension thecables 120. Alternatively, similar toFIG. 80 , a hinge could be included in thewall pole 116 in lieu of theroof pole 114 or both could include a hinge. Alternatively, the roof orwall pole cable 120. This could include a leverage handle for forcing the poles to extend and lock in place. Alternatively, the poles could screw outwards. In still another alternative, turnbuckles could be used on thecables 120 to create the tension. Thecrank assembly 156 shown and described with respect toFIG. 17 , however, is efficient in that it provides cable tension on allcables 120 through one central process. - In yet another alternative a combination of a
moveable cable hub 126 may be used in conjunction with one of the above mentioned methods of tensioning thecables 120. That is, therod 164 extending through theroof pole hub 124 and supporting thecable hub 126 may be telescoped down in the collapsed position to save on the length of thecollapsed tent 100. Then, once thetent 100 was initially expanded, thecable hub 126 androd 164 may be telescoped upward, slidably, screwed or otherwise, and locked in place. Once this initial process was complete, further cable tensioning methods mentioned above could be used. - In still another embodiment, an alternative window curtain system is shown. The
window curtain 414 shown inFIG. 81 is fastened to the bottom edge of thewindow opening 410 in theshell 104. As such, when thetabs 420 in the upper corners of thewindow curtain 414 are grasped to lower thewindow curtain 414, thecurtain 414 may fold inward creating a pouch shape or loop shape if viewed from the end. It is noted that thewindow curtains 414 of the present embodiment can only be opened in one direction due to the fixation to theshell 104. As such, in an alternative embodiment, thewindow curtain 414 may extend only partially (e.g. halfway) up thewindow opening 410. In this embodiment, anadditional window curtain 414 may extend from the top of thewindow opening 410 to the mid-height. The top andbottom curtains 414 could be opened alone or in combination to created various heights of exposedwindow opening 410. In one embodiment, a thin opening may be at the center of thewindow opening 410 may be created so a sitting person can see straight out a approximately eye level. This embodiment may help prevent wind and water from entering thetent 100 when thecurtain 414 is closed. This is in contrast to the slidingcurtains 214 shown inFIGS. 27-30 which are not fixed to theshell 104 at their bottom or top. - In still another embodiment, a window curtain 614 may slide to the side rather than vertically. In this embodiment, a window opening 610 may not be as wide as shown in previous embodiments, thus allowing for room for the window curtain 614 to slide before intersecting with an adjoining wall. In this embodiment, the window opening 610 may be a slot type window approximately 14″ wide by approximately 3″ to 4″ tall and may be located at eye level. Alternative sizes will be apparent to those of skill in the art and are thus within the scope of the present invention.
-
FIGS. 82-85 show yet another embodiment of ahinge 922. In this embodiment, ahinge 922 similar to that of described inFIG. 71 is shown. The hinge 992 in this embodiment may be made from a metal material or any other suitable material. Additionally, in this embodiment, acable guide swivel 929 is shown pivotally attached to theroof pole portion 978 of thehinge 922. As withFIG. 71 , acable stop 923 is included. As shown inFIGS. 84 and 85 , the collapsed position of thehinge 922 is shown. Also, extending from thecable guide swivel 929 is a threadedstud 931. In this embodiment, the threadedstud 931 is relatively long and includes a nut near thecable guide swivel 929 as well as a nut near the end of the threadedstud 931 and a cap nut. -
FIGS. 86-89 show the interaction between several threaded studs and thetent shell 104. InFIG. 86 , a threaded stud is shown extending from acable guide swivel 929. In the present position, thetelescopic rods 118 at the bottom of theframe 102 have not been extended and thecrank assembly 156 has not tensioned thecables 120. As such the threaded stud is positioned somewhat vertically. InFIG. 87 , these items have been completed and theshell 104 has tightened and rotated theguide swivel 929 to approximately 45 degrees. InFIG. 88 , an extended threadedstud 931 is shown similar to that shown inFIGS. 82-85 . This extended threadedstud 931 may function to support a rain fly, which prevents water from resting on the surface of theshell 104. As such, the rain is less likely to soak through thetent shell 104. The presence of a rain fly may also allow for venting in the roof of thetent 100 without causing water to enter the roof.FIG. 89 shows a similar threadedstud 933 extending from the top of thecable hub 126 through the top of thetent shell 104. Thisstud 933 may also be extended like the stud ofFIG. 88 to support a rain fly. In one embodiment, the rain fly may cover the whole roof and extend partially down the walls. The fly may have eyelets in all roof corners and at the top center of the roof. Additionally, the portions of the fly extending down the walls may be secured to a bungee extending from the fly to an anchor point on thetent 100 below the bottom of the rain fly. Preferably this anchor point may be near a tent corner. In many cases, theshell 104 of the tent may be reinforced at attachment locations by sewing reinforcing patches on the outer surface of theshell 104 to prevent tearing. - In still another embodiment, a
tent frame 102 may be used where some of the support legs 312 do not have an associated wall pole or telescoping rod. In this embodiment, thecable 120 associated with this particular support leg 312 may be attached to thecable hub 126 at one end and the end of theroof pole 114 at the other. As such, the tension in the cable will act to lift the opposite end of theroof pole 114 and may be used to prevent theroof 206 from sagging in certain circumstances. - In another embodiment, the
shell 104 may be adapted to hang and be supported from theframe 102 with tab loops through which the poles of theframe 102 may be sleeved. Alternatively, theshell 104 may be adapted to rest on the poles of theframe 102 and a rain/wind fly may be included to rest on thecables 120. - In another embodiment, the
tent 100 may include stakes which are inserted through loops in the bottom perimeter of the tent for further support and tautness. Additionally, thetent 100 may include ropes or ties extending from the hinge corners of thetent 100 downwardly angling away from thetent 100. The opposite end may then also be staked to the ground. - In yet another embodiment, the
shell 104 and frame 102 of atent 100 may be adapted to provide an open wall canopy. As such, theshell 104 may not have walls, but only a roof. In this embodiment, thecables 120 may extend beyond the hinge to a secure point near the hinge end of the wall pole rather than the sleeve end. Alternatively, thecables 120 may attach to the hinge end of the roof pole. Thehinge 122 in this embodiment may have a spring ball or other mechanical locking mechanism. - In still another embodiment, the tent may include additional cables separate and apart from the
cables 120. These additional cables may be placed to provide additional lateral support in the form of cross bracing between adjacent support legs or in other positions that will stiffen the structure. These additional cables may be positioned to avoid causing obstructions within the tent and may also be positioned to avoid interfering with the collapsibility of the tent. It is noted that a plurality of positions will be apparent to those skilled in the art and are within the scope of the invention. - In still another embodiment, the tent may be modularized so as to facilitate setting up a large tent. That is, several tents could be set up and placed adjacent to one another and the associated shells of the tents could be adapted to provide for one large fully or partially enclosed space.
- The tent described herein is advantageous for several reasons. First, the set up of the tent may require no assembly of parts, thus providing for quick and easy set up once a destination is reached. Second, the adjustability of the frame allows for a taut shell whether the shell has expanded or shrunk. This prevents noise due to the shell flapping from wind and may prevent damage to the shell. This may also add to the strength of the tent due to the circumferential tension provided to the wall poles. This leads to a third advantage, which is that the truss type system makes for a tent that is very sturdy and strong. Fourth, the window channels described herein allow for extremely quiet opening and closing due to the slidable channels used in lieu of zippers or hook and loop or other relatively noisy securing means. Moreover, the channels may hold the window curtains taut when closed further adding to the quietness of the tent. Fifth, the shape of the frame in conjunction with the shape of the shell and the location of the windows provides for unobstructed view out of the windows.
- This invention has been described herein in considerable detail in order to comply with the patent statutes and to provide those skilled in the art with the information needed to apply the novel principles and to construct and use such specialized components as are required. However, it is to be understood that the invention can be carried out by specifically different equipment and devices, and that various modifications, both as to the equipment and operating procedures, can be accomplished without departing from the scope of the invention itself.
- The description of the various embodiments is merely exemplary in nature and, thus, variations that do not depart from the gist of the examples and detailed description herein are intended to be within the scope of the present disclosure. Such variations are not to be regarded as a departure from the spirit and scope of the present disclosure.
