A structure is provided having a floor, and a canopy made from a flexible, substantially air-impermeable material and having a tubular rib. The canopy has an air inlet port by which the interior of the tubular rib can be connected to a source of compressed air, and is movable by the supply of compressed air from a collapsed state in which the tubular rib is deflated to an inflated state in which the tubular rib is inflated and supports the canopy in such a way that the canopy encloses an interior space above the floor and forms a roof and side walls of the structure. The floor has three substantially rigid floor panels which may be arranged together to form a substantially planar floor, or connected together to form the base and sides of a container in which the canopy can be stored when in the collapsed state.

A lightweight heat reflective shield useful for hikers and campers to reflect heat from a campfire back toward themselves. The heat reflective shield includes a base panel and a concave body portion attached to and extending upward from the base panel and supported by at least two inflatable ribs. The concave body portion includes an open front face along a front edge of the base panel, an inner side, and an outer side, wherein at least a portion of the inner side includes a heat reflective material. When the inflatable ribs are filled with air, the heat reflective shield may accommodate a standing or seated person, and when positioned adjacent a heat source, the heat reflective material of the inner side reflects heat from the heat source back toward the heat source.

A removable insulated floor for use with a portable shelter, the floor including a central section defining a ground engaging area and having at least three layers, at least one side wall extending upward from and being connected to the central section at an edge of the ground engaging area and having an outward facing side wall fastener, the central section includes at least one opening, and a central section fastener is connected to an upper layer of the central section and is located proximate the at least one opening, and at least one patch having a patch fastener connected to a lower surface of the patch and being releasably connected to the central section fastener located proximate the at least one opening. The floor is usable in combination with a portable shelter having complementary fasteners for releasable connection of the floor to the shelter.

[Summary] A shell element that can be formed simply and in a short time, a shell structure using the shell element, and a structure forming set that can form the shell element simply and in a short time are provided. Resin material is foamed on the inside of thin film, a foamed material portion with bubbles being mixed is in the state of being sandwiched by the thin film and a solid layer, and tensional stress is applied to the thin film and the solid layer and compressive stress is applied to the foamed material portion, thus the shell element is difficult to be cracked or split, and the shell structure is formed by the shell element. And, the shell structure forming set forms the shell structure easily.

Air supported structures forming an enclosure via internal pressurized air, and methods of making same, are disclosed. The structures include an outer membrane defining an outer surface of the structure. The structures include an inner liner blanket coupled to the outer membrane via a plurality of spaced baffles extending from the outer membrane into the enclosure, the inner liner blanket and the inner surface of the outer membrane forming a heating pocket therebetween within the enclosure extending along a first portion of the outer membrane. The structures also include at least one input channel in communication with the heating pocket, and at least one heated air system configured to selectively direct a flow of heated air through the at least one input channel and into the heating pocket to heat the first portion of the outer membrane to remove and/or prevent frozen precipitation accumulation on the outer surface thereof.

A shell element that can be formed simply and in a short time, a shell structure using the shell element, and a structure forming set that can form the shell element simply and in a short time are provided.

Resin material is foamed on the inside of thin film, a foamed material portion with bubbles being mixed is in the state of being sandwiched by the thin film and a solid layer, and tensional stress is applied to the thin film and the solid layer and compressive stress is applied to the foamed material portion, thus the shell element is difficult to be cracked or split, and the shell structure is formed by the shell element. And, the shell structure forming set forms the shell structure easily.

A temperature controlled inflatable tent is provided. The tent includes a base and one or more sidewalls forming an interior volume. The base and the one or more sidewalls each include a first layer and a second layer forming an enclosed interior volume disposed therebetween, wherein the interior volume retains air. A valve is in fluid communication with the interior volume of each the base and the one or more sidewalls. A first sidewall includes an opening having an inflatable door, wherein the door is removably secured to a perimeter of the opening via a fastener. A panel is disposed within the interior volume of the base, wherein the panel includes a heating and cooling element that is operably connected to a power source and a thermostat. The thermostat selectively actuates the heating and cooling element, such that an internal temperature of the tent can be set by a user.

The air dome includes one or several membrane shells made from plastic film material. It has on at least one longitudinal or transverse side a frame construction which is connected to the bordering membrane material, and in the frame profile at least one transparent film is incorporated, for forming a window front. The air dome includes one or several membrane shells made of plastic film. The membranes are formed as double-ply membranes with an outer and inner membrane and divided into strips. The strips can be connected along their longitudinal edges by means of a keder having a keder connection profile in a force-locked manner. Surface heat-reflective mats can have multiple layers of absorption-reducing air bubble film to reduce the transmission heat losses. The construction of such a constructed air dome can be handled by two people as well as the dismantling and the transporting and interim storage.

Embodiments include an outdoor activity structure, comprising: a wall that defines an interior room of the structure, the wall comprises an insulating layer disposed between an inner layer and an outer layer wherein the inner layer is coupled with the insulating layer by a plurality of inner seams and the outer layer is coupled to the insulating layer by a perimeter seam.
