Definitions

  • the present invention relates to sleeping chambers. More particularly, embodiments of the present invention relate to a lightweight, non-rigid, highly portable sleeping chamber that provides insulation against low temperatures and other environmental dangers even in relatively extreme conditions.
  • Tents are available in a variety of shapes and sizes, with features suited to a variety of conditions. Tents include rigid structures to create a cavity within which a person may repose, generally within a sleeping bag to stay warm. While some tents rely on a set of flexible rigid poles to provide a pop-up design requiring limited assembly time, most tents require efforts such as staking corners of the tent into the ground, positioning tent poles, and so forth. Generally, those devices which are most convenient to use are also very expensive to produce and purchase.
  • tents are inadequate. These include situations where the bulk of a tent is inappropriate, where the weight of a tent is unacceptable, or where the cost of a tent is prohibitively high. Nevertheless, persons in such situations may require protection from the elements and the ability to sleep in comfort.
  • the present invention relates to sleeping chambers. More particularly, embodiments of the present invention relate to lightweight, non-rigid, highly portable sleeping chambers that provide insulation against low temperatures and other environmental dangers even in relatively extreme conditions.
  • Implementation of the present invention takes place in association with a sleeping chamber having a double-wall inflatable structure to provide insulation against cold temperatures using a non-rigid form constructed of a lightweight material such as a polyethylene film.
  • the sleeping chamber is lighter in weight, smaller in bulk, and generally lower in cost than a conventional tent, while providing improved insulation against cold temperatures.

  • non-rigid structure 10 comprises an elongate tunnel 20 and a hood 50 , wherein tunnel 20 is capable of substantially enclosing at least one occupant 5 , and tunnel 20 is closed on one end 42 and open on the other end 44 .
  • two layers are used to construct the top 22 of tunnel 20 and to cause tunnel 20 to retain a concave or tunnel-like shape when inflatable space 30 filled with a gas or air.
  • the two layers 26 , 28 are sealed or otherwise coupled together to create at least one inflatable space 30 capable of retaining a gas (e.g., ambient air, etc.), thus forming a dead air space when inflated.
  • a gas e.g., ambient air, etc.
  • an inflation valve 46 provides access to inflatable space 30 so that a user can inflate space 30 by blowing air into valve 46 , which may be positioned inside tunnel 20 , outside tunnel 20 , or otherwise, as will be apparent to those skilled in the art.
  • valve 46 is designed or otherwise intended for use with an accessory air pump.
  • tunnel 20 includes, whether integrated or as an accessory, containers of compressed gasses of various types capable of automatically inflating inflatable space 30 .
  • the materials comprising tunnel 20 can be substantially flat, without a tunnel-like shape or form, and are capable of being folded, rolled, or otherwise greatly reduced in volume.
  • layers 26 and 28 of material that form top 22 of tunnel 20 are spot welded at intermittent points 32 to create a quilting or waffle-like pattern that aids in holding the position of the two layers 26 , 28 of material in relative positions to one another.
  • top 22 of tunnel 20 retains an enhanced shape when inflated via inflatable space 30 .
  • tunnel 20 comprises a height of approximately two feet or twenty-four inches when inflated with a first dead air space formed by inflatable space 30 comprising approximately one to one-and-one-half inches between layers 26 and 28 of material comprising top 22 of tunnel 20 .

  • Bottom 24 may comprise one or more layers of material that can be the same or may differ from the material used to construct top 22 .
  • bottom 24 comprises two layers 34 , 36 of material that may be sealed together to form a pocket 38 , which may be separate from inflatable space 30 .
  • Such a pocket 30 formed in bottom 24 may comprise a large slit 41 at one end so as to permit the insertion of a mat 40 , foam pad, or other material to act as an insulating material between a person lying in sleeping chamber 10 and the ground on which sleeping chamber 10 may be placed.
  • pocket 38 may comprise a complete seal at its perimeter, having a valve that permits inflation of the pocket 38 in a manner similar to or different from the method used to inflate inflatable space 30 in top 22 .
  • an additional dead air space may be provided to insulate the occupant 5 of sleeping chamber 10 from the ground and to provide additional comfort compared to lying on the ground alone.
  • the structure and cut of the materials comprising tunnel 20 is such that when inflatable space 30 is inflated, the bottom 24 curves at its open end 44 in a generally upward or cupping shape 43 so as to prevent water from easily entering tunnel 20 , thus aiding the comfort of occupant 5 .
  • this cupping shape 43 may extend approximately four to five inches above the ground.
  • Tunnel 20 may be affixed to the surface on which it lays, such as the ground when camping, by means of one or more optional loops 63 affixed to the sides of tunnel 20 along its length.
  • loops 63 affixed to the sides of tunnel 20 along its length.
  • stakes as are known in the art, may be inserted through such loops 63 and driven into the ground to retain the position of sleeping chamber 10 during sleep when winds or sloping terrain might otherwise cause undesired movement.
  • sleeping chamber 10 further comprises a hood 50 .
  • Hood 50 is typically made of a material similar to that of the tunnel, having characteristics such as puncture resistance, tear resistance, and water-resistance.
  • the materials used for hood 50 may differ from those used for tunnel 20 according to the desired requirements and characteristics of sleeping chamber 10 .
  • a colored material may be used for tunnel 20
  • a transparent material may be used for hood 50 .
  • a heavier grade material may be used for tunnel 20 to provide greater strength
  • a lighter grade material may be used for hood 50 to provide lighter weight.
  • hood 50 is attached to bottom 24 ; a portion of the material comprising hood 50 may be merely an extension of the material used to construct a portion of tunnel 20 .
  • a part of hood 50 may be constructed of at least two layers 52 , 54 , in the same manner as top 22 of tunnel 20 , and sealed so as to create an inflatable space 56 capable of retaining a gas.
  • a valve 48 affixed adjacent to space 56 a user may inflate space 56 by blowing into it, or by use of a pump, compressed gas device, or otherwise.
  • hood 50 may be rotated into place as shown in FIG. 1 over the open end 44 of tunnel 20 so as to enclose the open end 44 and provide substantially complete protection for occupant 5 .
  • hood 50 has a height of approximately thirty inches so as to provide a comfortable headspace for occupant 5 . Smaller or larger spaces may also be created by adjusting the inflation of space 56 or by using differing amounts of materials to create hood 50 .
  • hood 50 sits on or overlaps with the edge 60 of top 22 of tunnel 20 .
  • hood 50 may be attached to tunnel 20 by any means known in the art, including by means of one or more Velcro®-style pads, by a Ziploc®-style closure, by snaps, by hooks and eyelets, by zippers, or otherwise.
  • hood 50 does not form an airtight seal with top 22 of tunnel 20 because of the slightly differing contours of the two structures and because of the waffling that can be used to construct inflatable space 30 and space 56 , which can create a bumpy or irregular surface on either top 22 or hood 50 .
  • hood 50 sufficient air can flow between tunnel 20 and hood 50 so as to permit occupant 5 to breath comfortably.
  • a portion of hood 50 adjacent to space 56 includes an area of mesh material that directly permits air flow to occupant 5 .
  • tunnel 20 comprises two areas of dead air space: one between the two layers 26 , 28 when inflatable space 30 is inflated, and a second dead air space 62 between the bottom side of top 22 of the tunnel and the top of occupant 5 . These two areas of dead air space provide significant insulation against cold temperatures outside of sleeping chamber 10 .
  • occupant 5 places a sleeping bag 66 into sleeping chamber 10 , with sleeping chamber 10 acting as a one-person tent.
  • sleeping chamber 10 acting as a one-person tent.
  • occupant 5 lies in sleeping chamber 10 with only a blanket, with only the clothing he or she is wearing, or with no clothing, relying on the insulative properties of the dead air spaces just described as protection against the elements.
  • tunnel 20 may be constructed with an internal sock or sleeve 90 , which may be constructed of nylon or of any other suitable material.
  • an internal sleeve 90 may be used as a holder for accessories comprising various grades of material used to provide sleeping chamber 10 with different overall levels of insulation or heat retention. For example, an occupant might select a lightweight insert for use on a warm night, but might select a much heavier insert for use on a bitterly cold night.
  • sleeping chamber 10 in combination with an internal sleeve 90 and a selection of additional insert materials may act as a sleeping bag, providing variable levels of insulation via both dead air space and traditional insulative materials such as goose down, polyfill, or otherwise.
  • sheet of material may be placed across the open end 44 of tunnel 20 , where the sheet has a hole and operates as a gasket enclosing the head or head and shoulders of occupant 5 , preventing excess air flow between dead air space 62 and the space around the head of occupant 5 within hood 50 .
  • Sleeping chamber 10 may be constructed of any appropriate material as is known in the art. Typically, characteristics such as light weight, water resistance, wind resistance, low cost, tensile strength, resistance to air penetration, and puncture resistance are desired, though the selection of material based on these characteristics may vary based on the requirements of a particular use. For example, when used for emergency relief situations such as aiding the survival of earthquake victims in mountainous areas, a material of lower cost can be selected to permit the purchase of a larger number of sleeping chambers; conversely, a high performance use intended for outdoor enthusiasts might dictate the best combination of light weight and durability without regard to cost.
  • both tunnel 20 and hood 50 are constructed using a material having a thickness in the range of 1 mil to 4 mils.
  • various plastic films or metallic films are used, such as Mylar®, polyethylene, and/or others.
  • Sleeping chamber 10 may be used in any environment where insulation against cold temperatures is needed.
  • Non-limiting examples of such uses include camping, hiking, snowmobiling, fishing, and hunting; emergency preparedness; search and rescue operations; natural disaster and similar aid situations; military applications, both purpose-built and emergency use; and otherwise.
