BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates generally to a carrying bag for transporting portable structures used in outdoor sporting activities. More specifically, the present invention relates to a dual use carrying bag having a first configuration in which it is used as a carrying member for a collapsed or folded portable enclosure and, upon assembly of the portable enclosure, the carrying bag has a second configuration in which it is used as a floor member for the portable enclosure.
2. Brief Description of the Background Art
A wide variety of portable outdoor enclosures are used in an equally wide variety of outdoor sporting activities. Such enclosures range from lightweight hiking tents to large, heavy-duty lodge tents to hunting blinds to ice fishing shanties. Each type of enclosure has evolved to meet the specific needs and requirements of the particular sporting activity.
Because of the harsh conditions in which ice fishing takes place, shelters have long been used by ice fishermen. However, early structures were large, unwieldy wooden framed structures, that were towed out on the ice as an intact body. Although sturdy and somewhat weatherproof, these structures were not easily moved from place to place on a frozen body of water. Further, such structures could not be easily dismantled and moved to other fishing lakes. In keeping with the advent of modem tent technology, ice fishing enclosures now often employ technologies that provide collapsible, lightweight, and portable structures and that provide good protection from the elements.
The background art discloses many different outdoor enclosures of various sizes, shapes, and methods of construction. A primary goal in each of the designs for outdoor enclosures is to offer an effective shelter to protect the occupants from the elements of weather. Below, some examples of known approaches for assembling and fabricating sporting enclosures are described.
Collapsible, foldable, and easily disassembled frame structures are known. Examples of such structures are disclosed in U.S. patents to Beavers (U.S. Pat. No. 3,810,482), Foster (U.S. Pat. No. 4,938,243), and Stumbo (U.S. Pat. No. 5,628,338). Each of these patents show collapsible frames used to support a flexible covering for use as tents, blinds, or other shelters. Beavers and Stumbo each show frames which include support poles extending from a central hub, and Stumbo discloses a frame structure in which includes several sub-frames, each of which supports a portion of a flexible covering.
Many flexible coverings used in known collapsible enclosures are supported by the frame structures to provide the outer shell of the enclosure, and are commonly made of fabric. The flexible coverings normally include at least one door opening and one or more window openings. Window openings may be vacant, or alternatively, may be covered with transparent sheeting, screen, a closeable flap, or combinations thereof. Examples of such coverings are disclosed in U.S. patents to Smith (U.S. Pat. No. 3,709,237) and to Husted (U.S. Pat. No. 4,067,346), which each disclose respective fabric extensions at a lower edge of a covering, for use in securing the covering to the ground.
A variety of approaches have been used in the prior art to stabilize a collapsible enclosure in a desired location, in all types of weather environments. A common strategy is to stake the enclosure to the ground, either by securing a lead line between a buried stake and the enclosure, or by staking the flexible covering directly to the ground. A variety of tent stakes are known, for implantation in a variety of soil types. U.S. patent D 363,755 to Diederich depicts a tent stake including a threaded shaft.
Of the group of sporting enclosures, ice fishing tents provide features which address the particular requirements of this sport, which is performed in an extreme winter environment. Such enclosures must be able to accommodate high winds associated with broad open expanses of ice, and must protect the sportsperson from the environment. Such enclosures must also be portable, and should be capable of being easily assembled in very cold conditions. They must also provide access to the ice surface from the interior of the structure, while providing environmental protection. A variety of ice fishing tents are known, and examples thereof are found in US patents to Kashuba (U.S. Pat. No. 3,570,507), Klopfstein et al. (U.S. Pat. No. 4,926,893), and Thompson (U.S. Pat. No. 5,749,387).
Although the known sporting enclosures and ice fishing shanties are useful for their respective intended purposes, a further need still exists in the art for an improved apparatus for manually transporting the portable enclosures to a desired location within the unfavorable elements of winter weather. In particular, there is a need for an improved carrying device that can compactly and securely stow the portable enclosure while protecting the contents from the elements. Furthermore, there is a need for providing the portable enclosure with a means for further protecting the user from the effects long periods of inactivity on a cold ground surface. Specifically, an insulated barrier provided between the user and the ground surface would have positive benefits in terms of user comfort.
SUMMARY OF THE INVENTIONThe present invention provides a portable outdoor structure adapted for use in the field of ice fishing. A structure according to a selected embodiment of the invention is quickly and easily assembled and disassembled, provides protection from the harsh winter environment, and is sized and shaped to accommodate the space requirements of the sport of ice fishing.
Accordingly, in a first embodiment of the present invention, the inventive portable outdoor structure includes a durable, lightweight flexible covering or shell cooperatively mounted on an easily disassembled, lightweight frame structure to provide a floorless covered enclosure. The shell includes a skirt portion on each sidewall, in which the skirt portion extends out substantially parallel to a supportive substrate in an assembled configuration of the structure. The ends of the skirt portion extend out beyond the sidewall to which it is attached, on both sides of the sidewall. Adjacent skirt portion ends may be placed in an overlapping stacked configuration to align through holes formed therein, and to provide a strong reinforced spot for staking the housing to the ice surface or similar substrate.
The inventive structure also includes a plurality of anchor stakes adapted for use in securing the shell of the structure to an ice surface.
The flexible shell forms the plurality of walls and the roof of the enclosure, and is open at the bottom thereof. This feature is advantageous to the sport of ice fishing, because one or more holes can be formed in the ice within the enclosure, with no limitation on the placement thereof.
The lower edge of each sidewall of the shell is provided with a skirt portion extending therefrom. The skirt portion extends along substantially the entire lower edge of the covering, and has a width that is wider than the sidewall, such that the respective ends of the skirt portion extend beyond the sidewall on either side thereof. Each skirt end is provided with a rigid plastic or metal grommet. Thus, when in use, the skirt ends of adjacent sidewalls overlap one another in such a manner that the grommets overlie each other in stacked vertical alignment. The grommets are provided in the skirt ends for strength and reinforcement in staking the enclosure to the ice surface. Further, snow, rocks or weighted materials can be layered on the upper side of the skirt portion, to maintain the lower edge of the tent sidewalls adjacent the ice surface. This is especially helpful in windy conditions.
If desired, openings can be formed in the shell to provide doors, windows, and/or vents. For example, one or more flexible plastic windows may be provided in the walls of the enclosure, to admit light therein. These windows may also include flap closures. A zippered door is disposed on one of the walls to permit ingress and egress. A vent may be provided in the ceiling of the shell, to provide ventilation and to reduce or prevent moisture condensation within the enclosure.
The flexible shell is supported from within by a frame apparatus, which includes a plurality of individual, expandable sub-frames. A sub-frame is provided for the ceiling and each wall, and each sub-frame comprises a single central hub which supports a plurality of radially extending struts. The respective distal end portions of the struts are releasably attached to the outer shell, which may be accomplished by placing the strut ends into sewn-in pockets provided for that purpose on the interior of the shell.
Optionally, the ceiling and at least one wall of the shell may be provided with a respective tensioning strap, which is adjustable to place tension on the relevant fabric panel, in order to better withstand wind.
Inventive anchor stakes are also provided as supports for the enclosure, and these stakes allow the skirt portion of the covering to be easily and securely fixed to an ice sheet, the ground, or other supportive substrate without pounding, drilling, or excessive exertion. The inventive stakes include a threaded lower end having a spiral tip thereon similar to a corkscrew, and an upper end formed into a handle. The stakes are used at the corners of the portable enclosure, passing through the skirt portions of the covering, to hold the portable enclosure in a desired location.
A second embodiment of the invention provides an enclosure having similar construction but having a different outer shape. In particular, the illustrated second embodiment is a generally dome-shaped housing structure, which also includes skirt portions having stackable end portions similar to those provided in the first embodiment. The housing structure in the second embodiment is supportable by a segmented strut frame structure, which may be adapted to be placed either inside or outside of the housing, and which can be attached to the housing using either fabric or elastic loops.
The present invention also encompasses a kit for use in constructing a portable ice fishing enclosure. The kit includes a plurality of the described sub-frames, along with the shell, made of thin flexible material that fits over the frame, and which tolerates and repels the elements of weather encountered outdoors in the winter. The kit also includes a plurality of anchor stakes for attaching the enclosure to a substrate, and a carrying bag for ease of storage and transportation. The anchor stakes are threaded at the ends thereof, are adapted to be screwed into a supportive substrate, and are especially adapted for screwing into a thick ice sheet.
The present invention also encompasses a method of assembling the disclosed portable outdoor enclosure.
The present invention further encompasses a dual use bag for use as a carrying member for a collapsed or folded portable enclosure and, upon assembly of the portable enclosure, for use in combination with the portable enclosure as a floor member for the enclosure.
The inventive dual use bag is a large multi-layered sheet formed of a durable fabric which includes a thermally insulating pad layer. The outer face of the sheet is provided with plural sets of straps for use when the bag is used as a carrying member. The inner face of the sheet is free from straps and fasteners, and in the exemplary embodiment is used as the upward facing floor surface.
In its first use mode, the dual use bag is used to enclose a collapsed portable enclosure such as an ice shanty. The collapsed enclosure typically consists of multiple struts or strut sections and a fabric shell. These items are securely enclosed within the bag so that no inadvertent loss of parts is possible. The dual use bag includes binding straps which maintain the bag in a wrapped, surrounding relationship about the components of the enclosure, so that the components of the enclosure are compactly and securely stowed within the bag. The dual use bag also includes carrying straps which permit the bag to be carried by the user.
In its second use mode, the dual use bag is used in an opened, laid out configuration to provide a floor mat in combination with floorless portable enclosures such as hunting blinds and ice shanties. In such enclosures, the invention is used to provide an insulated, protective covering for the open ground area in the assembled portable enclosure. The insulated floor mat provides a thermal barrier to maintain the warmth of the user, especially when used on frozen ground or on ice. The insulation also provides a comfortable padded surface. When used on the ground, the mat provides a clean, dry location on which gear can be placed. This is also true when the mat is used on ice, with the additional benefit that any melting of ice or snow is isolated from the user and gear.
The inventive dual use bag is equally advantageous when used with portable enclosures having an integral floor such as camping tents. In such enclosures, the inventive dual use bag is placed within the enclosure overlying the integral floor, and provides an insulated, padded surface thereon. Use of the invention as a floor member would obviate the need for individual thermally insulated and padded sleeping mats such as those known by the registered trademark Therm-a-Rest, thereby reducing the amount of gear required for tent camping.
For a more complete understanding of the present invention, the reader is referred to the following detailed description section, which should be read in conjunction with the accompanying drawings. Throughout the following detailed description and in the drawings, like numbers refer to like parts.
The present invention is not limited to its application to the details of construction and to the dispositions of the components set forth in the following description or illustrated in the drawings. The present invention is capable of other embodiments and of being practiced and carried out in various ways. In addition, it is to be understood that the phrases and terms employed herein are for the purposes of illustration and example, and should not be regarded as limiting.

It is important, therefore, that the claims be regarded as including such equivalent constructions.
BRIEF DESCRIPTION OF THE DRAWINGS
First Embodiment—Overview
An illustrative embodiment of an inventive portable ice fishing enclosure according to the present invention will now be described, with reference to the drawing Figures. As shown in
The covering 20 is cooperatively supported by, and overlies the frame 70. The covering 20 provides an outer shell for the portable enclosure 10, and is formed of flexible sheet material. In the illustrated embodiment, the flexible sheet material is a woven synthetic fabric to provide the durability, flexibility and strength required for use in harsh environmental conditions.
The covering 20 includes a plurality of interconnected sidewalls 22 and a ceiling 24. The sidewalls 22 are arranged in a lateral edge-to-edge relationship, such that each of the sidewalls 22 is joined to an adjacent sidewall at each of its respective lateral edges, to form a closed section. The ceiling 24 is joined, at its peripheral edges, to the respective upper edges of the sidewalls 22, to close the upper end of the portable enclosure 10. The lower end of the portable enclosure 10 may be left open to allow the user to have access to substantially the entire ground surface area within the surrounding sidewalls.
Alternatively, if desired, a bag used to store and transport the enclosure in a collapsed configuration thereof may be adapted to be used as a floor in the assembled configuration of the enclosure, to cover part or all of the floor area inside of the enclosure.
The Outer Shell
In the first illustrative embodiment of the invention, shown in
One or more of the sidewalls 22 may be provided with a window opening 28. A transparent vinyl sheet insert 30 may be sewn over window opening 28, to allow natural light to enter into the interior space within the portable enclosure 10. The transparent vinyl sheet insert 30 may be covered with a selectively movable flexible window flap (not shown). If desired, only a portion of one edge of the transparent vinyl insert 30 may be fixed to a corresponding edge of the window opening 28 so as to allow the transparent vinyl insert 30 to be selectively openable. A selectively openable transparent vinyl insert 30 may also be layered over a screen insert (not shown).
The portable enclosure 10 includes at least one selectively closable door opening 36 formed in a sidewall 22, to permit ingress into, and egress from the enclosure 10. In the depicted embodiment, the door opening 36 is a closable door flap 38 that is secured to the sidewall 22 using conventional door closure means 40, which may include, but is not limited to, hook and loop fasteners, zippers, snaps, or ties.
A vent opening 42 is formed in the ceiling 24, and comprises a breathable vent insert 43 sewn therein which prevents environmental precipitation from entering into the interior of the enclosure 10, and which also allows adequate ventilation of the structure. The vent opening 42 may include a closable flap of fabric on the interior of the covering 20, and a screen panel may be provided as the vent insert 43.
The lower edge 44 of each sidewall 22 has a skirt portion 50 attached thereto along the entire width thereof, and the outer ends of skirt portion extend beyond the sidewall 22 at each side thereof. The skirt portion 50 is an elongate rectangular band formed of the same material as the tent body, and has a width that is greater than the width of the sidewall 22. The skirt portion 50 extends continuously along the entire lower edge 44 of the sidewall 22 such that the respective ends 54 of the skirt portion 50 extend beyond both lateral edges of the sidewall 22 (
In the assembled configuration of the enclosure 10, the sidewalls 22 extend substantially vertically upwardly, with each sidewall bowed slightly outwardly by its respective sub-frame 72 (
As shown in
The Frame
Referring now to
Each sub-frame 72 includes a substantially cylindrical central hub 74, and further includes a plurality of struts 76, which are pivotally mounted to the hub 74 and extend outwardly therefrom. In the illustrated embodiment, four struts 76 are provided for each hub. However, it is within the scope of this invention to provide a hub having a fewer or greater number of struts 76 to accommodate variations in sidewall shape. For example, to accommodate a triangular sidewall 22, the hub may include only three struts. As a second example, in a structure comprising five sidewall panels 22, the correspondingly hexagonal ceiling 24 would require a hub which includes 5 struts.
As seen in
The hub 74 also has a plurality of mounting apertures 98 formed therein. One mounting aperture 98 is provided for each strut 76. In the illustrated embodiment, four struts 76 are provided for each hub 74, and thus each hub 74 includes four mounting apertures 98. The mounting apertures 98 are positioned so as to surround, and be equidistantly spaced about, the axial centerline of the hub 74.
Each mounting aperture 98 includes an axially extending shaped through hole 99. The through holes 99 extend through the block of the hub 74, between the inner face 94 and the outer face 92. The inner surface of each through hole 99 is irregularly shaped, and includes both a pair of opposed key slots 102 and a stop slot 116. The hub 74 has a stop surface 118 formed therein at a lower end of the stop slot 116.
Each mounting aperture 98 further includes a plurality of radially extending grooves 100 formed in the outer face 92 thereof. Each of the radial grooves 100 extends radially inwardly from the peripheral edge surface 96 so as to terminate at and communicate with a respective mounting aperture 98.
Each strut 76 consists of an elongate semi-rigid rod having a shaped hub end 164 for mounting within the mounting apertures 98, and a distal end 166 opposed to the hub end 164. The rod may be made of a strong, flexible material such as plastic, a carbon composite tube, or fiberglass. The hub end 164 of each strut 76 includes a transversely extending pin which forms a key 110 positioned adjacent to the terminus of the hub end 164, and also includes a narrow, outwardly extending stop 114 formed on the terminus of the hub end 164. During assembly and in use, the key 110 is received within and pivotably supported by the key slots 102 of the through hole 99. Likewise, the stop 114 is supported by the stop surface 118 in the stop slot 116 of the through hole 99.
Once assembled, each strut 76 is positioned within the hub 74 such that the hub end 164 resides within a mounting aperture 98. Specifically, in the unfolded and opened position of the sub-frame 72 shown in
Once the struts 76 are positioned within the respective mounting apertures 98, the inner face 94 of the hub 74 is covered with a circular flat hub cap 104. The hub cap 104 includes a central hole 103, which aligns with a threaded bolt hole 120 formed through the axial centerline of the hub 74. The hub cap 104 is maintained on the inner face 94 of the hub 74 using a threaded bolt 106, extending through both the central hole 103 of the hub cap 104 and the bolt hole 120 of the hub 74, and secured with a nut 105. The inner end of the bolt 106 is looped to form an eye 135.
Eye 135, formed on the end of bolt 106, provides a means for grasping the hub 74, and may support a short pull strap to enhance that function (see the hub 74 of the ceiling 24 in
In the preferred embodiment, the eye 135 of the bolt 106 is located on the outer surface of the portable enclosure 10, and provides an attachment structure to which an end of an adjustable cinch strap 156 (described below) is secured. A cinch strap 156 is secured between the structurally substantial hub 74, via the eye 135, and the substrate 5, via an anchor stake 130, 230 (described below). This configuration is provided on each sidewall of the enclosure, so that each sub-frame 72 is individually fixed to the substrate 5.
An improved embodiment of the sub-frame 72′ is depicted in
In the improved embodiment sub-frame 72′, a strut stabilizer 121 is used to improve the function and reliability of the sub-frame 72.′ As seen in
The strut stabilizer 121 limits movement of the struts 76 in the hub mounting apertures 98, and also applies pressure to the keys 110 formed in the hub ends 164, thereby stabilizing the struts 76 relative to the hub 74 and permitting smooth movement of the struts 76 within the hub 74. The strut stabilizer 121 (
Each sub-frame 72 is cooperatively supported in space by the covering 20, such that sub-frames 72 on adjacent portions of the portable enclosure 10 are not in physical contact with one another. The distal ends 166 of each respective strut 76 are received in and supported by pockets 64 formed on the interior surface 62 of the covering 20 (
Tensioning Straps
A tensioning strap 150 may, optionally, be provided on the interior surface 62 of the covering 20 for use with one or more panels thereof. Thus one or more of the sidewalls 22 and the ceiling 24 of the portable enclosure 10 may be provided with a tensioning strap 150. Each tensioning strap 150, where used, includes strap sections 152, 154 which extend between a pair of opposed edges of a respective portion of the covering 20, such as a sidewall 22 or ceiling 24, and are centrally joined using a tensioning mechanism 160. The tensioning mechanism 160 can be of a conventional type similar to a known tensioning mechanism used in automotive safety belts, which allows a single-direction adjustment of the overall length of the straps 152, 154.
The internal structure of one example of a tensioning mechanism 160 is shown in
In the tensioning strap 150 according to the present invention, a first, adjustable length strap 154 is formed of a strong, flexible material. An example of such a material includes, but is not limited to, nylon webbing. Adjustable length strap 154 has opposed first and second ends 155, 157, and is pre-threaded through the tensioning mechanism 160. A user of the apparatus is not required to remove the adjustable length strap 154 from the tensioning mechanism 160, or to re-thread the adjustable length strap 154 therethrough at any time during the life of the mechanism, under normal circumstances.
The tensioning strap 150 further includes a second, fixed length strap 152 operatively attached to the adjustable length strap 154 via the tensioning mechanism 160. The fixed length strap 152 is formed of a strong, flexible material, similar to the material of the adjustable length strap 154. The fixed length strap 152 has opposed first and second ends 151, 153. The first end 151 of the fixed length strap 152 is operatively and non-adjustably attached to the tensioning mechanism 160. This may be accomplished by passing the end of the strap around the end of the base plate 162, through the opening 164, and sewing the strap back on itself, as shown in
As seen in
For example, in
As seen in
When setting up the enclosure 10, the distal ends 166 of the struts 76 are inserted into the corresponding pockets 64 at the corners of a selected sidewall panel 22, with the outer face 92 of the hub 74 oriented facing outwardly, against the material of the sidewall 22. The hub 74 is then pushed outwardly until it bows out beyond a plane which includes the corners of the sidewall 22, in a gently bowed configuration similar to an open, unfurled umbrella.
Adjustable tension cinch straps 156 may also be used on the exterior of the enclosure 10 to secure the enclosure 10 to the substrate 5 (
One end of the cinch strap 156, for example the fixed length strap 159, is secured to the eye 135 of the bolt 160 by conventional means. In the illustrated embodiment, a loop is provided at the strap end, so that in use, the loop is passed through the eye and about the cinch strap 159 itself. The second end of the cinch strap 156, for example the adjustable length strap 158, is secured to the stake 230 by conventional means. In the illustrated embodiment, a loop is provided at the strap end, and in use, the loop is hooked about the handle 232 of the stake 230 in order to retain the cinch strap 156 thereon.
The Anchor Stakes
The portable enclosure 10 is maintained in contact with the ice or other substrate surface 5 using a plurality of anchor stakes 130, 230. This can be accomplished as seen in
A description of each anchor stake 130, 230 is provided below. It is understood that the anchor stakes 130 and the anchor stakes 230 disclosed herein are provided with distinct features which optimize their respective functions when used as described. However, the anchor stakes 130, 230 also have many common features, and so there are circumstances in which they may be used interchangeably.
As seen in
The lower end 138 of the shank 134 is tapered, and terminates in a pointed tip 140. For ease of threading into an ice surface 5, the tapered portion may be two inches or more in length. The lower end 138 is provided with coarse exterior threads 142, and at the tip 140 the shank 134 is provided with a generally helical shape, in the manner of a corkscrew. As a result, the tip 140 is oriented at an angle θ relative to the longitudinal axis of the shank 138 (
Each anchor stake 130 is also provided with a flange 136 formed between the handle 132 and the lower end 138. The flange 136 is a thin plate extending in a direction normal to the longitudinal axis of the shank 134. The flange 136 has an outer diameter that is greater than the diameter of the reinforcing grommets 60 of the through holes 58 formed at each end 54 of the skirt portion 50. To prevent the flange 136 from passing through the grommets 60, the diameter of the flange 136 should be at least twice the diameter of the through holes formed in the grommets 60. In use, the lower end 138 of anchor stake 130 is inserted into a through hole pair 66 of the skirt portion 50, and is drawn into the surface of the substrate 5 by manually turning the handle 132. The flange 136 provides a stop surface when anchor stake 130 is sufficiently screwed into the ice, such that the layered ends 54, 54 of the skirt portion 50 are tightly sandwiched between the ice surface 5 and the flange 136. Use of a threaded anchor stake provides simple and quick securement to the ice surface, in contrast to a prior art method of chipping a hole for a stake, and adding water to freeze the stake therein.
As seen in
The lower end 238 of the shank 234 is tapered, and terminates in a pointed tip 240. For ease of threading into a hard or compacted surface 5, the tapered portion may be two inches or more in length. The lower end 238 is provided with coarse exterior threads 242, and at the tip 240 the shank 234 is provided with a generally helical shape, in the manner of a corkscrew. As a result, the tip 240 is oriented at an angle θ relative to the longitudinal axis of the shank 238 (
Second Embodiment—Overview
As shown in
The shell 220 is cooperatively supported by the frame 350, which may be set up for placement either inside or outside of the shell. The shell 220 for the portable enclosure 210 is formed of flexible sheet material, which may be nylon or another woven synthetic fabric to provide the durability, flexibility and strength required for use in harsh environmental conditions.
The shell 220 includes a plurality of interconnected sidewalls 222. The sidewalls 222 are arranged in a lateral edge-to-edge relationship, such that each of the sidewalls 222 is joined to an adjacent sidewall at each of its respective lateral edges, to form a substantially closed section.
In the embodiment of
Alternatively, if desired, a bag used to house and store the enclosure in a collapsed configuration thereof may be adapted to be used as a floor in the assembled configuration of the enclosure, to cover part or all of the floor area inside of the enclosure 210.
In the embodiment shown in
One or more of the sidewalls 222 may be provided with a window opening 228. A transparent vinyl sheet insert 230 may be sewn over the window opening 228, to allow natural light to enter into the interior space within the portable enclosure 210. The transparent vinyl sheet insert 230, where used, may be covered with a selectively movable flexible window flap 232. If desired, only a portion of one edge of the transparent vinyl insert 230 may be fixed to a corresponding edge of the window opening 228, so as to allow the transparent vinyl insert 230 to be selectively openable. A selectively openable transparent vinyl insert 230 may also be layered over a screen insert (not shown).
The portable enclosure 210 includes at least one selectively closable door opening 236 formed in a sidewall 222, to permit ingress into, and egress from the enclosure 210. In the depicted embodiment, the door opening 236 is a closable door flap 238 that is secured to the sidewall 222 using a conventional door closure which may include, but is not limited to, hook and loop fasteners, zippers, snaps, or ties.
A vent opening 242 is formed in an upper portion of one of the sidewalls 222, and comprises a breathable vent insert 243 sewn therein, which allows adequate ventilation of the structure. The vent opening 242 may include a closable flap of fabric 244 on the interior or exterior of the covering 220, and a screen panel may be provided as the vent insert 243.
The lower edge 245 of each sidewall 222 has a skirt portion 50 attached thereto along the entire width thereof, and the outer ends of the skirt portion extend beyond the sidewall 222 at each side thereof. The skirt portion 50 is an elongate rectangular band formed of the same material as the sidewalls, and has a width that is greater than the width of the sidewall 222. The skirt portion 50 extends continuously along the entire lower edge 245 of the sidewall 222, such that the respective ends 54, 54′ of the skirt portion 50 extend beyond the respective lateral edges of the sidewall 222. Each end 54, 54′ of the skirt portion 50 is provided with a through hole 58. The edges of the through hole 58 are reinforced. In the illustrated embodiment, the through hole 58 is reinforced with a metal or high-strength plastic grommet 60.
In the assembled configuration of the enclosure 210, the sidewalls 222 extend substantially upwardly at an angle inclined towards the center, and the skirt portion 50 for each sidewall 222 extends out parallel to the substrate 5 and perpendicular to the sidewall 222, so as to overlie and confront the surface of the substrate 5.

It will be understood that suitable fabric or elastic loops may be provided on the interior or the exterior upwardly extending seams of the shell, to receive the frame strut sections 354, 355 therein.
Method of Assembling the Portable Enclosure
The present invention also provides a method of assembling the portable ice fishing enclosure 10. One example of a method which may be used for assembling the portable shelter are as follows:
Step 1. Position the covering on the ground or ice surface 5 so that an exterior surface 63 of the ceiling faces upwardly, an interior surface 62 of the ceiling 24 confronts the ice surface 5, and so that the sidewalls 22 are situated below the ceiling in a collapsed manner.
Step 2. From the inside of the housing, secure one of the sub-frames 72 to the interior surface 62 of one sidewall 22 by inserting the distal end 166 of each strut 76 into a respective pocket 64 on the interior surface 62 of the sidewall 22, with the outer face 92 of the hub oriented facing outwardly, against the material of the sidewall.
Step 3. The hub is then pushed outwardly until it bows out past the corners of the sidewall 22, in a gently bowed configuration similar to an open, unfurled umbrella.
Step 4. Repeat steps 2 and 3 for each remaining sidewall 22 and also for the ceiling 24, until all respective sidewalls 22 and the ceiling each have a sub-frame 72 secured to an interior surface 62 thereof.
Step 5. (optional) Actuate the tensioning mechanism 160 of the tensioning strap 150 for any sidewall panels 22 or ceiling 24 having tensioning straps thereon, until the respective fabric panel is pulled taut across the sub-frame 72. The fabric is thereby made more wind-resistant.
Step 6. Arrange the skirt portions 50 over and parallel to the ice surface or other substrate 5, and each end 54 of the skirt portion 50 is arranged to lie in a layered, overlapping relationship with the end 54′ of the skirt portion 50 of the adjacent sidewall 22′ such that through hole 58 of an end 54 of the skirt portion 50 of one sidewall 22 overlies and is in vertical alignment with the through hole 58 of an end 54′ of the skirt portion 50 of the adjacent sidewall 22′ to form a vertically aligned through hole pair 66.
Step 7. For each vertically aligned through hole pair 66, insert an anchor stake 130 into the through hole 66 pair such that the tip 140 of the tapered, threaded lower end 138 contacts the ice surface 5.
Step 8. For each through hole pair 66, turn the handle 132 of the anchor stake 130 with downward pressure applied to the stake, so that the threads 142 of the lower end 138 draw the anchor stake 130 into the ice surface 5 until the flange 136 abuts the respective skirt end 54.
A similar method would be followed for the enclosure 210 of

It is understood that contents of the kit can be varied to accommodate enclosures comprising different components. For example, a second embodiment kit 300 (
Dual Use Bag
The inventive dual use bag 490 will now be described with respect to the figures. The dual use bag 490 is used as a carrying member (
As seen in
The bag 490 includes an outer surface 412, and an inner surface 414 opposed to the outer surface. The outer surface 412 corresponds to the side of the bag 490 which faces outward when bag 490 is used as a carrying member. The carrying straps 440 and binding straps 442 are fixed to the outer surface 412 of the bag 490 using known methods. In the illustrated embodiment, the straps 440, 442 are sewn to the outer surface of the bag 490. When the bag 490 is used as a floor mat, the outer surface 412 is oriented so as to confront the ground (or ice) surface.
An insulation layer 418 is provided. The insulation layer 418 may be the same size and shape as the bag 490 so as to extend to the entire outer periphery of the bag 490, as shown in
In the exemplary embodiment shown in
An example of a synthetic fabric used for the first 416 and third 420 layers includes 600D or 1000D polyester. However, those skilled in the art understand that other similar, equally durable fabrics may be substituted for the polyester. The insulation layer 418 is also synthetic so as to benefit from the high thermal efficiency, low weight, and drying properties of synthetic insulations.
The side of the bag 490 which is designated as the outer side 412 may be treated with a waterproofing compound, so that when used as a carrying member, the contents of the bag 490 are maintained in a dry condition, and so that when used as a floor mat, the ground moisture is not absorbed into the bag 490.
In an alternative construction, the bag 490 may be formed of a single layer 416 of durable synthetic fabric with a layer of insulation 418 sewn thereon (
Plural sets of straps are provided on the exterior surface 412 of the outer layer 416 of the bag 490 (
The binding straps 442 are formed of elongate sections of wide synthetic webbing. Plural binding straps 442 are arranged in a parallel configuration so as to lie in the transverse direction of the bag 490. Each binding strap 442 is provided in a length which permits a first end 445 of the binding strap 442 to be fixed to the bag 490 at a position generally mid way between the longitudinal centerline C of the bag 490 and a longitudinally-aligned long side 426, and a second end 447 of the binding strap 442 to extend beyond the opposed long side 424 so as to reside at a position spaced from the long side 424. Thus, the second end 447 of the binding strap 442 extends outward from the long side 424 of the bag 490, and the body of the strap 442 and the first end 445 of the strap 442 confront the outer surface 412 of the bag 490.
Each binding strap 442 is fixed to the bag 490 by conventional means such as sewing. The entire length of the confronting portions of each binding strap 442 and the bag 490 may be sewn together. Alternatively, short seam fragments may be provided at spaced intervals along the confronting portions of each binding strap 442 and bag 490 so as to firmly attach the binding strap 442 to the bag 490. The first end 445 and the second end 447 of each binding strap 442 are each provided with a cooperating connecting member, as described below.
In the embodiment illustrated in
The carrying straps 440 are formed of elongate sections of wide synthetic webbing. As shown in
Each carrying strap 440 is provided with a generous length such that the second end 443 of each carrying strap is spaced a long distance from the short end 430 of the bag 490 when the carrying strap 440 is fully extended. Specifically, each carrying strap must be of sufficient length to extend along the entire longitudinal dimension of the bag 490 in the folded and packed configuration. In addition, each carrying strap must be of sufficient length to allow adequate slack for receiving the shoulder of a user between the carrying strap and the folded and packed bag 490.
The outer-surface side of the second end 443 of each carrying strap 440 is provided with a cooperating connecting member, as described below.
In the illustrated embodiment, the first end 441 of each carrying strap 440 is provided with a pad member 444. The pad member 444 may be integrally formed with the carrying strap 444. Alternatively, the pad member 444 may be a separate component which is secured to the first end 441 of the carrying strap 444. The pad member 444 surrounds each carrying strap 440 at portions extending from the first end 441 of the carrying strap 440 to a position of carrying strap 440 adjacent to, and spaced apart from, short end 430 of the bag 490.
When the inventive bag 490 is used as a carrying member, the bag 490 is carried on both shoulders of the user in the style of a backpack. Specifically, a carrying strap 440 is placed on each shoulder of the user such that the pad member 444 is interposed between the carrying strap 440 and the shoulder surface, thereby allowing the bag 490 to be easily and comfortably carried (
However, alternative configurations of the carrying straps 440 can be provided. A first example is a configuration which provides a single elongate padded strap, attached at opposed ends of the bag 490 in the folded and packed configuration so as to allow the bag 490 to be carried at the side of the user's body with the strap supported on the user's shoulder. A second example is a configuration in which a pair of short straps are provided in a parallel arrangement to allow the bag 490 to be carried in the hand of the user. The inventive bag 490 is not limited to the described strap configurations, but may instead use other equally effective configurations, or combinations thereof.
The opposed ends of the binding straps 442 and the carrying straps 440 may be secured to each other using any conventional connecting means, including, but not limited to, hooks, clips, snaps, quick-release fittings, ties, and hook and loop fastener. In the illustrated embodiment, a hook member 450 (
In a similar manner, a hook member 450 is provided at the second end 443 of each carrying strap 440. A pair of slot members 452 is sewn to the outer surface 412 of the bag 490 at a position adjacent the opposed short side 428 of the bag 490, and in longitudinal alignment with, a respective carrying strap 440. Each slot member 452 is configured to cooperatively receive therein the hook portion 454 of the hook member 450 formed on the outer surface-facing side of the second end 443 of the carrying strap 440.
For each binding strap 442 and each carrying strap 440, one of the hook member 450 and slot member 452 is provided with a strap adjustment means. In the case of the binding strap 442, the adjustment means allows the binding strap 442 to be firmly and securely tightened about the bag 490 and its contents (
Method of Using the Dual Use Bag as a Carrying Member
A method of using the bag 490 as a carrying member will now be described. As an illustration, the method will include the portable enclosure 10 as the object carried within the bag 490. However, it is understood that the bag 490 can be used to carry portable enclosures other than the specific embodiments of portable enclosures described above. The method of using the bag 490 as a carrying member has the following method steps:
Step 1) Place the bag 490 on the ground surface 5 such that the outer surface 412 faces downward and confronts the ground surface 5, and such that the inner surface 414 faces upward (
Step 2) Place the collapsed, disassembled portable enclosure 10 on the inner surface 414 such that the portable enclosure is generally positioned in the center of the bag 490 (
Step 3) Fold the bag 490 along a longitudinally extending fold line such that the long side 426 overlies the disassembled portable enclosure 10. It should be noted that the long side 426 is opposed to the long side 424 from which the binding straps 442 extend, and thus the long side without binding straps 442 is used as the first-folded side.
Step 4) Fold the bag 490 along a longitudinally extending fold line such that the long side 424 overlies both the disassembled portable enclosure and the first folded side 426 (
Step 5) For each binding strap 442, connect the first end 445 to its respective second end 447 using the cooperative connecting means 450, 452. In the illustrated embodiment, the connecting operation includes inserting the hook portion 454 of the hook connector 450 into the slot portion 456 of the slot connector. It is understood, however, that the cooperative connecting means 450, 452 is not limited to this type of connector, and instead can be comprised of equivalent connecting structures as described above. By connecting the first end 445 of each binding strap to its respective second end 447, opposed longitudinal sides of the bag 490 are secured to each other.
Step 6) Adjust the length of each binding strap 442 so that no slack remains in the body portion of each binding strap 442, and so that the portable enclosure is snugly circumferentially surrounded in the transverse direction by the bag 490 and binding straps 442.
Step 7) Fold the bag 490 along a transversely extending fold line such that the short side 428 overlies the portable enclosure, and both long sides 424, 426. It should be noted that the short side 428 is opposed to the short side 430 from which the carrying straps 440 extend, so that the short side without binding straps is used as the third-folded side. By folding the bag 490 in this manner, the slot connectors 452 secured to the outer surface 412 adjacent to t the short side 428 are now positioned on an upper side of the folded bag 490.
Step 8) Fold the bag 490 along a transversely extending fold line such that the short side 430 overlies the portable enclosure and both long sides 424, 426. In this configuration, the short side 430 confronts and is spaced apart from the opposed short side 428. Note that the short side 430 is the side from which the carrying straps 440 extend, so that the short side with carrying straps is used as the fourth-folded side. In this configuration, the portable enclosure is completely surrounded by and enclosed within the plural folds of the bag 490.
Step 9) For each carrying strap, connect the hook connector 450 formed on each respective second end 443 of each carrying strap 440 to a longitudinally aligned slot connector 452 positioned adjacent short side 428. In this manner, the opposed short sides 428, 430 are secured to each other using the carrying straps 440.
Step 10) Adjust the length of each carrying strap 440 so that minimal slack remains in the body portion of each carrying strap 440, and so that the portable enclosure is snugly circumferentially surrounded in the longitudinal direction by the bag 490 and carrying straps 440 (
Step 11) Mount the carrying bag on the shoulders of a user by placing the bag 490 adjacent the upper trunk portion of a user so that the pad member 444 of each carrying strap overlies an upper surface of a shoulder of the user, and so that the short sides 428, 430 of the bag 490 in the folded configuration confront and abut the body of the user (
Although the method of using the dual use bag 490 as a carrying bag has been described using only binding straps 442 and carrying straps 440 to secure the contents within the bag 490 and to carrying the bag 490, it is well within the scope of this invention to provide additional securement structures at strategic locations on the outer surface 412 or inner surface 414 of the bag 490 in order to securely maintain the bag 490 in its folded configuration during use. For example, a fastening means such as hook and loop fastener may be strategically and intermittently placed between overlapping surfaces of the folded bag.
Method of Using the Dual Use Bag as a Floor Mat
A method of using the bag 490 as a floor mat will now be described. As an illustration, the method will include the portable enclosure 10 as the body in which the floor mat is disposed. However, it is understood that the bag 490 can be used as a floor mat in portable enclosures other than the specific embodiments of portable enclosures described above. The method of using the bag 490 as a floor mat has the following method steps:
Step 1) Place the folded and bound bag 490 on a ground surface 5 such that the short sides 428, 430 of the bag 490, as well as the carrying straps 440, face upward (
Step 2) Disconnect the respective first and second ends 441,443 of the carrying straps 440.
Step 3) Unfold the short sides 428, 430 of the bag 490 so that the short sides 428, 430 of the bag 490 overlie and confront the ground surface (
Step 4) Disconnect the respective first and second ends 445, 447 of the binding straps 442.
Step 5) Unfold the long sides 424, 426 of the bag 490 so the long sides 424, 426 of the bag 490 overlie and confront the ground surface 5, and so that the collapsed, disassembled portable enclosure 10 is fully accessible (
Step 6) Assemble the portable enclosure 10 and position it on the ground surface 5 as desired.
Step 7) Place the carrying bag 490 on the ground within the portable enclosure 10 such that the outer surface 412 confronts the ground surface, such that the inner surface 414 faces upward, and such that the carrying bag 490 is fully laid out in a non-self-overlapping and generally flat, planar configuration (
