The portable shelter 100 is a self-erecting structure that is deployed to create a private space within a public setting. The portable shelter 100 enables a person to change clothing, go to the bathroom, and perform other personal tasks in a private manner while outdoors in a public or the like. In this respect, before explaining the current embodiments of the portable shelter 100 in detail, it is to be understood that the portable shelter 100 is not limited in its applications to the details of construction and arrangements of the components set forth in the following description or illustration. Those skilled in the art will appreciate that the concept of the present disclosure may be readily utilized as a basis for the design of other structures, methods, and systems for carrying out the several purposes of the portable shelter 100.

(7) FIG. 1 illustrates the portable shelter 100 in an installed state thereof. As discussed, the portable shelter 100 is a self-erecting structure that can be popped-up to create a private space for suitable applications while outdoors. For this purpose, the portable shelter 100 includes a cover 102 and a supporting frame 104. The supporting frame 104 is a collapsible structure that supports the cover 102. While in the installed state of the portable shelter 100, the cover 102 encloses the supporting frame 104 for the purpose of creating the private space. As illustrated in FIG. 1, the cover 102 may completely wrap around the supporting frame 104. It may be understood that the cover 102 may generally be a piece of cloth. In the present embodiments, the supporting frame 104 may be a spring or a coil loaded structure to provide stiffness to the supporting frame 104 for supporting the cover 102 thereon, while the portable shelter 100 is in the installed state.

(8) In one or more examples, the supporting frame 104 may include one or more coils 106. The coils 106 are stored in a tension bearing state while the supporting frame 104 is in a collapsed state (as illustrated in FIG. 2). This configuration allows the portable shelter 100 to use the energy stored within each of the coils 106 to expand the supporting frame 104. The coils 106 within the supporting frame 104 are arranged inside the cloth of the cover 102 such that the coils 106 will cause the supporting frame 104 to extend into a tubular or cylindrical shaped structure (as shown in FIG. 1) without need of any human intervention. Although, the supporting frame 104 has been described in terms of having more than one coils 106, it may be appreciated that, in other examples, the supporting frame 104 may have one continuous coil without any limitations.

(9) Further, as illustrated, the portable shelter 100 may include two or more feet 108 to support the supporting frame 104, while in the installed state. In the present examples, the portable shelter 100 includes four number of feet 108 (as better shown in FIG. 2) arranged substantially equidistantly along circumference at a bottom of the supporting frame 104. In one or more examples, the feet 108 are foldable wire feet which are arranged in an extended vertical manner when the portable shelter 100 is in the installed state, and otherwise in a folded or bent horizontal manner when the portable shelter 100 is in the collapsed state. The feet 108 may be made of bendable wires which may be easily bent or folded by application of some force to be transformed from a folded position to an unfolded position, and vice-versa. Such foldable wire feet are well known in the art and thus have not been described in detail herein. In one exemplary configuration, the feet 108 may be designed to support the supporting frame 104 about 5 inches from the ground, or to be pushed into the ground, as required for supporting the portable shelter 100 in the installed state.

(10) Further, as illustrated in FIG. 1, the portable shelter 100 may include a zipper 110 extending at least partially along a vertical length of the cover 102. As may be understood, the zipper 110 may be opened to provide ingress and egress into the portable shelter 100 when in the installed state, and closed to prevent access to interior space thereof. The zipper 110 may be regular zipper as known in the art. In some other examples, the zipper 110 may be replaced by ties or knots without any limitations. Further, the portable shelter 100 may include two lookout windows 112 (only one shown in the accompanied drawings) arranged diametrically opposite along the supporting frame 104, while the portable shelter 100 is in the installed state. The windows 112 may be arranged right above the zipper 110, as shown in FIG. 1. In one exemplary configuration, the windows 112 may measure about 10 inches wide and about 3 inches tall. In some examples, the windows 112 may be provided with shields 113 for each of the two windows 112. In one example, the shields 113 may in the form of a mesh, a curtain or the like. The shields 113 may be arranged on the inside wall of the cover 102, around the windows 112, to close off the windows 112 when required for complete privacy of the interior space in the portable shelter 100.

(11) Further, as illustrated, the portable shelter 100 may include a dome cover 114. The dome cover 114 may generally be hemispherical in shape. The dome cover 114 is placed on top of the cover 102 to fully cover the interior space of the portable shelter 100. It may be understood that the dome cover 114 may protect the interior space of the portable shelter 100 from rains and the like. Also, as illustrated, the portable shelter 100 may have two or more tethers 116 which may be attached to and extending from the cover 102 proximal to top thereof. In the illustrated embodiments, the two or more tethers 116 are shown to include two ropes. Such ropes may measure about 2-4 feet in length. The tethers 116 are used to tie and restrain the cover 102, and thereby the portable shelter 100, to a tree or some other object if necessary, so as to provide stability to the portable shelter 100 in the installed state, for example, in case of high winds or the like.

(12) In an embodiment of the present disclosure, the portable shelter 100 is provided with a splash-guard liner 118 arranged in the interior space of the cover 102. In particular, the splash-guard liner 118 may be arranged along a bottom third of the height of the cover 102. The splash-guard liner 118 may be made of plastic or similar material. The splash-guard liner 118 may be employed for using the portable shelter 100 as a private restroom, for example, so that the user may use the portable shelter 100 as a toilet for urinating inside thereof, without worry of splashes being bounced therefrom. The splash-guard liner 118 may be removably arranged in the interior space of the cover 102 when required. In one example, the splash-guard liner 118 may be attached to inner wall of the cover 102 by means of quickly detachable fasteners, such as Velcro. Such arrangement allows the splash-guard liner 118 to be removed from the interior space for cleaning the same after use, as and when required.

(13) As discussed earlier, FIG. 2 illustrates the portable shelter 100 in the collapsed state. The portable shelter 100 includes retaining straps 120 to hold the supporting frame 104 and the cover 102 in position, when the portable shelter 100 is placed in the collapsed state. The retaining straps 120 may be in the form of bands or webbings that holds the coils 106 of the supporting frame 104 in tensioned position, when the portable shelter 100 is in the collapsed state. The retaining straps 120 may or may not be elastic. The retaining straps 120 are wrapped around the cover 102 and the supporting frame 104, when the portable shelter 100 is in the collapsed position. The retaining straps 120 may further include some form of locking means (not shown), such as a buckle or the like, to constrain against and restrict the tension force of the coils 106, while the portable shelter 100 is in the collapsed position.

(14) In one or more exemplary configuration, the cover 102 may have dimensions with a height of about 6-7 feet when extended fully, and further a diameter of about 3-5 feet to allow a user to conveniently stand inside the interior space of the portable shelter 100, such as for purpose of changing clothing and/or for urinating and the like. In general, the portable shelter 100 may be manufactured in a range of sizes, with each size being large enough to accommodate the physical movements required by a user to disrobe and put on clothing freely and safely in the interior space thereof, when in the installed state. In the present examples, the cover 102 of the portable shelter 100 may be made of vinyl and plastic materials which are generally opaque to provide privacy to the user. Furthermore, the cover 102 may be made of dark materials to further enhance opaque effect.

(15) It may be contemplated that when the portable shelter 100 is needed for use, the user first loosens the retaining straps 120, unfolds the feet 108 and extends the supporting frame 104 by slightly pulling the coils 106, so that the cover 102 stands vertically as a tall tube. The user may then unzip the zipper 110 to access interior space inside the cover 102 and place the splash-guard liner 118 therein if required. The user may further unzip the zipper 110 for privacy during use. After use, the user may get out from the interior space by unzipping the zipper 110 and stepping out, push down the coils 106 and then locks the retaining straps 120 to again dispose the portable shelter 100 in the collapsed state, for example for transportation to some other place or the like.

(16) The portable shelter 100 of the present disclosure provides a private way to change clothing, go to the bathroom, and perform other personal tasks while outdoors. The portable shelter 100 conceals the user completely for privacy. The portable shelter 100 is compact, portable, versatile, lightweight and easy to use, i.e. to be disposed between the collapsed state and the installed state, and vice-versa. The portable shelter 100 is ideal for long-distance trips, hiking, camping, backpacking, beach visits, road trips, parties, BBQs, etc. In some examples, the portable shelter 100 may be used as changing rooms which are commonly used in the clothing industry to allow patrons to try on clothes prior to selecting the clothes, for example, at remote locations such as sidewalk sales, yard sales and the beach. The portable shelter 100 promotes convenience, relief, and peace of mind for the user as it ensures provision of a private space when required.

(17) The foregoing description conveys the best understanding of the objectives and advantages of the present invention. Different embodiments may be made of the inventive concept of this invention without affecting the scope of the present disclosure. It is to be understood that all matter disclosed herein is to be interpreted merely as illustrative, and not in a limiting sense.
