This invention features a portable privacy enclosure including a bottom panel for engaging an underlying supportive surface such as the ground, a porch floor or deck, or an indoor floor. There are a first pair of side panels foldably attached to the bottom panel along a first side edge thereof, and a second pair of side panels foldably attached to the bottom panel along an opposite second side edge thereof. Respective fasteners releasably interconnect the first pair of side panels to one another and the second pair of side panels to one another. There is a first end panel foldably connected to the bottom panel along a forward edge of the bottom panel that extends between the respective side edges of the panel. A second end panel is foldably connected to the bottom panel along an opposite rearward end of the bottom panel that extends between the respective sides of the bottom panel. Each of the end panels is releasably fastened to a respective one of the first side panels and a respective one of the second side panels. The enclosure has an open upper end that permits sun to illuminate the inside of the enclosure. Each of the side and end panels includes an opaque material that affords privacy to a person lying within the enclosure with the panels fastened to one another in an assembled condition. Between uses, the adjoining side and end panels are unfastened from one another and collapsed sequentially onto the bottom panel. The entire assembly is then folded into a compact and portable condition.
In a preferred embodiment, the panels comprise a fabric or mesh material. Each of the side and end panels may be bounded by a square or otherwise rectangular frame, which may be composed of wire, tubing, plastic, wood or fiberglass. With each of the side and end panels in a collapsed or folded condition, the bottom panel may be folded in half so that the product is placed in its portable condition. A handle may be utilized for carrying the collapsed enclosure.

There is shown in FIGS. 1–3 a portable privacy enclosure 10 designed for use in sunbathing and other activities in which the user desires at least some degree of privacy. Enclosure 10 is designed primarily for outdoor use and is intended to be set up on the ground (e.g. typically on a grass or sand underlying surface) or alternatively on a pool, patio or porch floor or deck. It should be noted, however, that the privacy enclosure may also be used indoors in situations where the user desires improved privacy (e.g. in airport lobbies). The enclosure includes an open top and a bottom or floor panel 12 that is a flexible sheet typically composed of a fabric such as canvas or some other type of durable mesh material. Lightweight wood or plastic may also be used. A first pair of side panels 14 and 16 are foldably connected to bottom panel 12 along one of the longitudinal (e.g. typically head to toe) sides. Likewise, a second pair of side panels 18 and 20 are foldably or collapsibly connected to an opposite longitudinal side of the floor panel. As best shown in FIG. 1, each of the side panels includes a square or otherwise rectangular frame 22 having upper and lower horizontal pieces 24 and 26, as well as vertical side pieces 28 and 30 extending between pieces 24 and 26. A gusset or bracket 23 comprising a strip of wood or plastic is connected at each corner of frame 22 to strengthen the frame. Canvas, wire mesh or other opaque fabric screening material 32 is mounted to each frame 22. For example, fabric 32 may be stapled, tacked or otherwise fastened to the frame. In certain embodiments, each frame may include a pair of conforming segments that are pressed together or sandwiched about the fabric piece 32. Each of the fabric segments 32 may be unitarily connected to bottom panel 12. Alternatively, the bottom panel may be fastened by stitching or otherwise (see stitching 33 in FIG. 4) to lower horizontal strips 26 of frames 22 in a manner similar to which the side panel fabric segments 32 are attached to the frame 22. In any event, each of the side panels 14, 16, 18 and 20 is foldable relative to bottom panel 12, as indicated by double-headed arrows 34.
A similar pair of opposing end panels 36 and 38 are attached foldably in a like manner to respective forward and rearward ends of lower panel 12. Each of end panels 36 and 38 includes a square frame 40 comprising a pair of parallel upper and lower horizontal pieces 42 and 44, as well as a pair of parallel vertical pieces 46 and 48 that interconnect horizontal pieces 42 and 44. A piece of fabric 50 is mounted within frame 40 in a manner similar to that used to mount fabric 32 within frames 22, i.e. by stapling, VelcroTM, adhesives, tacks, etc. Once again, fabric segments 50 may be connected unitarily or in one piece to bottom panel 12. Alternatively, pieces 50 used in end panels 36 and 38 may be separate from bottom panel 12 and the bottom panel may be secured at its respective ends to lower pieces 44 of respective end panels 36 and 38. As with the side panels, end panels 36 and 38 are foldable or collapsible as indicated by double-headed arrows 52 in FIG. 2.
To erect or assemble enclosure 12, the collapsible side and end panels 14, 16, 18, 20, 36 and 38 are raised into the generally vertical, elevated or upright condition shown in FIGS. 1–3. The adjoining panels are fastened together by various means. For example, as shown in FIGS. 1–3 and more particularly in FIG. 4, each pair of adjoining side and end panels may be fastened together by means a pair of two-part hook and loop (e.g. VelcroTM) fasteners 60. Typically, a hook component 61 is carried along an edge of the frame in one of the panels; a complementary piece of loop material 63 is similarly carried by a corresponding mating surface of the frame of an adjacent panel. Components 61 and 63 are selectively interengaged to secure together the adjacent panels and hold those panels in an upright condition, which is best depicted in FIGS. 1 and 3. A pair of fasteners 60 are typically formed along each of the interengaging surfaces of the adjacent panels. More particularly, the corresponding individual fastening components are formed at equivalent heights along the respective adjoining panels.
As best illustrated in FIG. 1, bottom panel 12 has a length that is somewhat greater than the total length of the aligned side panels 14 and 16 (or analogously panels 18 and 20). By the same token, bottom panel 12 is wider than end panels 36 and 38. As a result, when the enclosure is initially set-up, as shown in FIG. 1, and the side and end panels are raised into an upright condition, a gap G is formed between each adjacent pair of panels. In order to secure the panels together, the panels are manipulated by moving the adjacent panels into interengagement such that the corresponding hook and loop components carried by the respective panels are interengaged. The flexible sheet material comprising bottom panel 12 allows the bottom panel to conveniently collapse so that the adjacent panels may be moved easily into engagement with one another. For example, in FIG. 1 panels 14 and 16 are slid or otherwise pushed into abutting end-to-end interengagement such that the panels are secured together by hook and loop fasteners 60 in the manner shown in FIGS. 2 and 3. This operation is performed for each adjacent pair of side and end panels. For example, in FIG. 4, loop component 63 carried by end panel 36 is pushed into interengagement with hook component 61 carried by side panel 14. The extra material of bottom panel 12 located between each end panel and its respective side panels once again allows the bottom panel to collapse so that the panels may be moved easily into an interengagement with one another. When all of the panels have been fastened together, the enclosure 10 is fully erected in the upright condition depicted in FIGS. 2 and 3.
An alternative means for fastening the adjacent panels together includes one or more straps as depicted in FIG. 4A. Typically, the strap is mounted through an opening 62 in one corner of each of the panel frames 22 and 40. In FIG. 4A, the junction between a representative side panel 16 and a representative end panel 38 is shown. The strap 60 extends through an opening 62 in one corner of frame 22 of panel 16. With both panels 16 and 38 in a raised condition, strap 60 is interengaged with a complementary hole 64 in the adjoining corner of frame 40 of panel 38. After strap 60 is inserted through hole 64, the strap is tied such that the adjoining panels 16 and 38 are fastened together and support each other in an upright condition. This type of connection may be used to interconnect both the adjoining side panels and each adjoining pair of side and end panels in a manner analogous to the hook and loop fasteners depicted in FIGS. 1–3. It should also be understood that a wide variety of alternative fastening means may be employed. For example, the adjoining panels may be held in place in an assembled condition by assorted types of clips, brackets, hook and loop fasteners, clamps, etc. The particular means for fastening the adjoining panels in an upright condition is not a limitation of this invention.
To employ enclosure 10 for sunbathing or other outdoor applications, the user typically first lays out the enclosure in a flat, collapsed condition upon a selected underlying surface (e.g. the ground, a deck, etc.). Bottom panel 12 lies flat upon the underlying surface and the side and end panels extend outwardly therefrom and likewise lie flat upon the underlying surface. The user may then place a beach towel, lounge chair, etc. upon the underlying surface. The user next raises each of the side and end panels and fastened the adjoining panels together by means of fasteners 60 or otherwise. With enclosure 10 in a fully assembled condition, user U may lie upon a towel or mat placed within the enclosure, as shown in FIG. 3. The screening material 32 and 50 within each panel effectively guards the user's privacy. Privacy is maintained while the user sunbathes.
After sunbathing is completed, enclosure 10 may be collapsed for transportation or storage in the manner shown in FIGS. 5 and 6. First, each of the fasteners 60 is disengaged. The side and end panels are then allowed to collapse or fold as indicated by arrows 70 in FIG. 5. More particularly, opposing side panels 14 and adjoining end panel 36 are stacked on one side of bottom panel 12. Opposing end panels 16 and 20 and adjoining end panel are similarly stacked upon the opposite end of the bottom panel. The precise order in which the side and end panels may be folded over may be varied within the scope of this invention. In any case, after the side and end panels are collapsed, the bottom panel is folded longitudinally in half (i.e. across a lateral fold line) so that a collapsed stack of panels is achieved in the manner shown in FIG. 6. Enclosure 10 effectively assumes the shape of a single square panel, with each of the individual side and end panels stacked upon one another. The bottom panel is effectively folded into two half sections, each of which has a size generally resembling the size of each side and end panel. The folded or collapsed panels may be secured together by VelcroTM fasteners, snap fasteners, straps or other means. A handle H may be attached to the panels in order to facilitate transportation of the collapsed enclosure. The handle may comprise a pair of U-shaped straps attached respectively to panels at the top and bottom of the stack. The handle may be composed of leather, plastic or other materials. As best shown in FIG. 6, the collapsed product assumes a compact shape that is conveniently portable and easy to store between uses.
It should be understood that enclosure 10 may have various dimensions within the scope of this invention. Typically, the length of the enclosure (i.e. the length of the adjoining pair of side panels 14, 16 and 18, 20 should be at least 6 feet so that an adult can lie comfortably head-to-toe between the end panels 36 and 38. The width may vary, although the enclosure should be at least approximately 3 feet wide so that the end panels 36 and 38 have a size generally comparable to each of the side panels. By utilizing a length that is approximately twice the width, the panels may feature like dimensions so that the panels are folded and stacked in a conforming, compact and convenient fashion. Closure and storage are thereby facilitated. Various alternative dimensions may be utilized within the scope of this invention.
The material comprising the frame may be varied. Wood, fiberglass, PVC, wire and alternative materials may be employed. In a like manner, the fabric forming the bottom panel and the obscuring material of the side and end panels may be altered. Canvas and an opaque mesh are preferred, although a wide variety of other materials (i.e. wood, flexible or rigid plastics, etc.) may be employed.
As previously stated, the privacy enclosure is not limited to use for sunbathing. It can alternatively be used for various other indoor and outdoor applications where the user requires privacy and wherein the portability of the apparatus is important.
Accordingly, the present invention provides for a collapsible, portable privacy enclosure and, more particularly, to a product featuring a plurality of releasably interconnected side walls that function as privacy panels and which are foldable into a conveniently transportable unit. While this detailed description has set forth particularly preferred embodiments of the apparatus of this invention, numerous modifications and variations of the structure of this invention, all within the scope of the invention, will readily occur to those skilled in the art. Accordingly, it is understood that this description is illustrative only of the principles of the invention and is not limitative thereof.
Although specific features of the invention are shown in some of the drawings and not others, this is for convenience only, as each feature may be combined with any and all of the other features in accordance with this invention.
Other embodiments will occur to those skilled in the art and are within the following
