Portable shelter system
A portable shelter system is constructed from two portable shelters. Each portable shelter is provided with an enclosure having a front wall configured with a door and a rear wall configured with an opening. The opening of each rear wall is fitted with first and second zippers about the perimeter of the opening. A second door fitted with a mating zipper is reversibly connected to the first zipper. A sleeve having opposing first and second perimeter edges is fitted with mating zippers that connect to the second zippers of each opening when the rear walls of the two portable shelters are adjacent to and spaced from one another.

BACKGROUND OF THE INVENTIONPortable ice fishing shelters are known that consist of a lightweight polymer sled and a flexible enclosure supported by a pivotable, collapsible frame carried by the sled. Typically, the flexible enclosure has a rear wall and a portion of two side walls anchored to three sides of the sled. When the pivotable frame is extended, a front wall of the enclosure is spaced from the sled to define an interior area for occupants.
A common manner of accessing the interior of the portable ice fishing shelter is to pivot the frame from a retracted position to the extended position while the occupant is located on or near the sled. To avoid the need for an occupant to pivot the frame to a retracted position to exit the interior and thereby minimize exposure to wind and cold temperatures, a zippered door is known to be provided in the front wall of the enclosure. Such portable ice fishing shelters are generally sized to accommodate one or two individuals and their ice fishing gear. It would be advantageous to have a portable shelter system that retains the qualities of compactness, light weight and easy set-up, yet has greater interior space for additional occupants and their gear.
BRIEF SUMMARY OF THE INVENTIONA portable shelter system comprises first and second enclosures, each of which is defined by a plurality of walls comprised of opposing end walls and interconnected side walls. One end wall of each enclosure is configured to define an opening having a perimeter edge that comprises first and second reversible mechanical connecting mechanisms. The one end wall of the first enclosure is positioned adjacent to and spaced from the one end wall of the second enclosure. A sleeve having spaced first and second circumferential edges comprises third and fourth reversible mechanical connecting mechanisms which engage the second reversible mechanical connection mechanisms of the first and second enclosures.
BRIEF DESCRIPTION OF THE DRAWINGS
The rear wall 20 of known portable shelters of the variety described have been either comprised an uninterrupted material or have incorporated a sewn-in clear material that functions as a window. As shown in
As shown in
As further shown in
The assembly of portable shelter system 10 is accomplished by positioning the rear wall 20 of two portable shelters 12 and 14 adjacent to and spaced from one another. Zipper 32 of each portable shelter 12 and 14 is then engaged with zippers 36 and 38 of sleeve 26 to connect sleeve 26 to portable shelter 12 and 14. One of zippers 32 or zippers 36 and 38 may be provided with double pull sliders to enable connection and detachment of zippers 32 from zippers 36 and 38 from either the outside or inside of portable shelter system 10. Door 34 of each portable shelter 12 and 14 is unzipped and opened to allow occupants to access and/or to communicate between their respective interiors. Doors 34 may be zipped closed when desired such as for purposes of privacy or to reduce the interior space a user may wish to heat. The portable shelter system of the present invention provides a quick and easy way of joining two independent, compact, light-weight and easily transportable portable shelters, allowing expanded interior space for occupants and their gear.
Portable shelter system 50 takes advantage of the inventive concept of forming an opening in a wall of a portable shelter that is smaller than the wall and interconnecting two such configured portable shelters via sleeve 26. Each of the portable shelters 54 has an opening of common size and shape in at least one wall of the shelter and is joined to portable shelter 52 using sleeves 26, which are connected to the portable shelters 54 by zippers or other suitable mechanical fastener, in the manner described above with respect to
Although the present invention has been described with reference to preferred embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention.
Claims
1. A method of forming a portable shelter system comprising:
- providing first and second enclosures, wherein each enclosure has a plurality of side walls, each enclosure comprising: a first side wall configured with a first opening and a door mateable with the first opening; a second side wall opposite the first side wall, the second side wall configured with a second opening having a perimeter edge, first and second reversible mechanical connecting mechanisms being attached to the second side wall adjacent the perimeter edge; and a second door configured for connection to the first reversible mechanical connecting mechanism;
- providing a sleeve having a circumference and spaced first and second circumferential edges, each of the first and second circumferential edges comprising third and fourth reversible mechanical connecting mechanisms, respectively;
