## Background
FIELD OF THE INVENTION
The present invention relates to privacy shelters. More particularly, the invention relates to portable collapsible privacy shelters.
BACKGROUND
People often spend hours cooking, drinking, and socializing outside arenas and stadiums before sporting events, rock concerts, or other events at so-called tailgate parties. Frequently, the attendees will need to use a toilet but, due to distance from the party site, poor sanitation of the facilities, or other reasons, attendees are often dissuaded from doing so. Additionally, at events in the fall or spring, changing outdoor temperatures may cause some attendees to wish to change their clothes to lighter or heavier clothing, depending on the circumstances. Attendees generally will not change their clothes in public, and public toilets are frequently not used due for changing clothes due to their cleanliness. Some try to change clothes in a car or other motor vehicle, but the windows of the vehicle undermine attempts at modesty and the seats and low roof of vehicles prevent attempts to stand and dress. Additionally, some have attempted to use upstanding tent-like shelters for tailgating but, especially in windy conditions, their efficacy is limited. Various other forms of privacy shelters have been developed, but they all have limitations that make them unsuitable for some applications.
SUMMARY
The present invention solves the above-described problems and provides a distinct advance in the art of privacy shelters. More particularly, the present invention provides a privacy shelter that is portable, collapsible, easy to transport, assemble and disassemble, and will not tip in windy conditions.
One embodiment of the portable shelter of the present invention broadly includes a lower section, an upper section, a roof section, and a stabilization component. The lower section and the upper section each include a back wall, side walls having inwardly-folding hinges, a front wall, and a door. The upper and lower sections may be folded flat, like an accordion, along their hinged side walls for convenient transport in a trunk, truck bed, or the like, and then extended for assembly. The roof section comprises a frame and a roof. The upper and lower sections may further include shelf members for securing the sidewalls in position, and a plurality of fastening mechanisms for securing the sections together.
In use, the lower section, upper section, and the roof may be transported in a collapsed configuration to an assembly site. There, the lower section and the upper section are each extended. The upper section is placed on the lower section and the shelf members are extended to secure the upper section and the lower section in an extended configuration. The lower section is removably attached to the upper section with the fastening mechanisms and, likewise, the upper section is attached to the roof with a plurality of fastening mechanisms. After use, the shelter may be quickly and easily disassembled by reversing the above steps.
In another embodiment, the inwardly-folding hinges of the side walls of the upper and lower sections and the hinges between each door and each front wall of the upper and lower sections of the privacy shelter may use inwardly-folding living hinges. Additionally, hinges between adjacent walls may use continuous hinges.
In another embodiment, the back wall, side walls, and door of the upper and lower sections further include removable panels that may be customized with logos, advertisements, mascots, or the like. In some embodiments, the removable panels are display screens that are operable to display static, rotating, or moving images.

Advantageously, the stabilization component 18 may be transported without water or sand to reduce the cost of shipping the privacy shelter 10.
FIGS. 4-11 illustrate use of the privacy shelter 10. The privacy shelter 10 is first transported to a location with the lower section 12, upper section 14, and roof section 16 collapsed. As shown in FIGS. 4 and 5, in some embodiments, the collapsed lower section 12, the collapsed upper section 14, and the roof section 16 are substantially the same length and width and may be stacked in a compact manner for transport in a trunk, truck bed, or the like.
To assemble the privacy shelter 10, the collapsed lower section 12, the collapsed upper section 14, and the roof section 16 are separated, as shown in FIG. 5. The right and left side walls 24, 26 of the lower section 12 and right and left side walls 80, 82 of the upper section 14 are each extended so adjacent walls are at a generally perpendicular orientation, as shown in FIG. 6. As shown in FIG. 7, the upper section 14 is raised and placed upon the lower section 12 so the lower edge 152 of the upper section 14 engages the upper edge 154 of the lower section 12. The roof section 16 is similarly placed upon the upper section 14 so the lower edge 148 of the roof section 16 engages the upper edge 150 of the upper section 14.
Turning in particular to FIGS. 8-9, the shelf member 32 of the lower section 12 is pivotally extended from a position generally parallel to the front wall 28 of the lower section 12 to a position generally perpendicular to the front wall 28 of the lower section 12. When extended, a lateral edge of the shelf member 32 is disposed near to an interior face of the right or left side wall 24, 26 of the lower section 12 and, thus, prevents the left or right side wall 24, 26 from folding inward. In some embodiments, the distal edge of the shelf member 32 engages a flange or recess within the back wall 22 of the lower section 12 and, thus, is secured in position by the flange or recess and by the force of gravity acting on the shelf member 32. In some embodiments, the shelf member 32 may also be secured in position against the front wall 28 with a latch, hook, or other attachment mechanism. Some embodiments utilize two or more self members 32 to provide additional security and rigidity by securing both the right side wall 24 and the left side wall 26.
Similarly, the shelf member 88 of the upper section 14 is pivotally extended from a position generally parallel to the front wall 84 of the upper section 14 to a position generally perpendicular to the front wall 84 of the upper section 14. When extended, a lateral edge of the shelf member 88 is disposed near to an interior face of the right or left side wall 80, 82 of the upper section 14 and, thus, prevents the right or left side wall 80, 82 from folding inward. In some embodiments, the distal edge of the shelf member 88 engages a flange or recess within the back wall 78 of the upper section 14 and, thus, is secured in position by the flange or recess and by the force of gravity acting on the shelf member 88. In some embodiments, the shelf member 88 may also be secured in position against the back wall 78 with a latch, hook, or other attachment mechanism. Some embodiments utilize two or more self members 88 to provide additional security and rigidity.
As best shown in FIGS. 9-11, the lower section 12 and the upper section 14 may be secured together by using a plurality of fastening mechanisms 34 disposed on the upper edge 154 of an interior face of the lower section 12 and a mating fastening mechanism 90 disposed on a lower edge 152 of an interior face of the upper section 14. The upper section 14 and roof section 16 may be secured together using a plurality of fastening mechanisms 90 disposed on the upper edge 150 of an interior face of the upper section 14 and a mating fastening mechanism 146 disposed on a lower edge 148 of an interior face of the roof section 16.
When secured, each wall 78, 80, 82, 84 of the upper section 14 is secured to the corresponding wall 22, 24, 26, 28 of the lower section 12 to form a unitary whole. Similarly, the door 86 of the upper section 14 is secured to the door 30 of the lower section 12 to form a unitary whole. Additionally, the roof section 16 is secured to an upper edge of the upper section 14 to form a unitary whole. Thus, when assembled, the lower section 12, upper section 14, and roof section 16 combine to form a sturdy structure. Users may choose to place a portable toilet within the interior space 20 of the privacy shelter 10.
When the user wants to move the privacy shelter 10, the privacy shelter 10 may be collapsed by performing the assembly steps in a generally reverse order.
Turning to FIGS. 12-19, another embodiment of a privacy shelter 200 is illustrated. This embodiment is substantially similar to the privacy shelter 10 of FIGS. 1-11, except where indicated. In this embodiment, the privacy shelter 200 broadly comprises a lower section 202, an upper section 204, and a roof section 206.
The lower section 202 includes a back wall 208, side walls 210, a front wall 212, and a door 214 that are each fabricated from plastic and utilize a continuous hinge 216 between adjacent walls 208, 210, 212. Additionally, each side wall 210 utilizes a living hinge 218 along a generally-vertical central axis so each side wall may fold inward, like an accordion, along the living hinge 218. This embodiment also uses a living hinge 220 along an edge 222 between the front wall 212 and the door 214.
The upper section 204 includes a back wall 224, side walls 226, a front wall 228, and a door 230 that are each fabricated from plastic and utilize a continuous hinge 232 between adjacent walls 224, 226, 228. Additionally, each side wall 226 utilizes a living hinge 234 along a generally-vertical central axis so each side wall may fold inward, like an accordion, along the living hinge 234. This embodiment also uses a living hinge 236 along an edge 238 between the front wall 228 and the door 230.
In this embodiment, the roof section 206 is a unitary rectangular cap for positioning on an upper edge of the upper section 204 that is fabricated from plastic and, in some embodiments, may be translucent to obscure the inner space 238 of the privacy shelter 200 while allowing exterior light to enter.
Turning to FIG. 20, another embodiment of a privacy shelter 300 is illustrated. This embodiment is substantially similar to the privacy shelter 200 of FIGS. 12-19, except as indicated. Though this embodiment is depicted with reference to the privacy shelter 300, the features of this embodiment may be used with other embodiments without deviating from the scope of the invention.
In this embodiment, the privacy shelter 300 further includes removable panels 302 disposed in the back wall (not shown), each side wall 304, and door 306 of other upper section 308 and disposed in the back wall (not shown), each side wall 310, and door 312 of the lower section 314. In some embodiments, the removable panels 302 may be removably secured with latches, screws, adhesive, or the like. In some embodiments, the removable panels 302 include logos, team emblems, mascots, advertising, or the like, on an inner, outer surface, or both.
In some embodiments, the removable panels 302 may further include an LCD, OLED, OLED, AMOLED, or the like, on an inner surface or outer surface of the removable panels 302, or both. Thus, the removable panels 302 may be operable to display advertisements, animated logos, or the like, inward or outward. Inward-facing displays may also provide a light source for a user when inside a closed privacy shelter 302.
The above described embodiments of a privacy shelter provide numerous advantages over prior art privacy shelters. For example, the privacy shelter may be easily transported and assembled while remaining sturdy in windy conditions. The privacy shelter provides enhanced privacy and cleanliness by providing space without windows where users may readily and quickly change clothes. Additionally, when used with a portable toilet, the privacy shelter provides convenient and truly portable restroom facilities.
Although the invention has been described with reference to the preferred embodiment illustrated in the attached drawing figures, it is noted that equivalents may be employed and substitutions made herein without departing from the scope of the invention as recited in the claims.
