A flexible hinge created by a section of fabric material disposed between upper and lower retention pieces, for creating a hinge from a fabric member.

A T-link hinge for hingeably connecting first and second members comprises a link portion having a T-shaped cross-section including a top region and a bottom region, wherein the top region has a width greater than a width of the bottom region. The link portion comprises first and second thru holes formed in the bottom region of the link portion adjacent each the respective first and second ends of the link portion. Each of the first and second members to which the link portion is to be mounted includes thru holes. In an assembled configuration of the link portion and the first and second members, the thru holes formed on the first and second members axially align with the pair of thru holes in the link portion and are connected by first and second pins.

This invention describes a 3-layer insulation material (10) comprising a first fabric layer (12), a second fabric layer (14) and a third fluted intermediate fabric layer (16) between the first and the second fabric layers (12, 14), the fluted intermediate fabric layer (16) being attached alternately to the first and the second fabric layer (12, 14) with longitudinal seams (18a-18n) forming longitudinal channels (20a-20n) for the insulation material (22) having individual insulation material (22) bundle in-side each longitudinal channel (20a-20n). Also disclosed are a method and an arrangement for producing the same.

Portable multi-layer warmth delivery systems and methods may pertain to an electrically resistive first layer, a structural second layer, and an infrared-redirecting third layer. By passing an electrical current through the electrically resistive first layer, infrared energy is emitted, redirected, and efficiently concentrated in a vicinity.

An outdoor item such as a sleeping bag, jacket, hat or blanket with one or more ventilation/temperature adjustment openings. Each ventilation/temperature adjustment opening includes a fastening mechanism that when opened, an opening is formed in the outer layer and insulative material/layer of the sleeping bag but not in the inner layer, allowing the outdoor item to vent better, thereby cooling an occupant using or wearing the outdoor item thereby offering temperature regulation.

A method for providing cushioning for sleeping bags is provided. The method also comprises determining dimensions of a lower surface of an unfurled sleeping bag. The method also comprises receiving a section of spacer fabric of surface shape and dimensions approximating the dimensions of the lower surface. The method also comprises inserting the section into a pliable container of shape and dimensions accommodating the section. The method also comprises sealing the container and attaching the container to the lower surface of the unfurled sleeping bag.

The present invention provides light weight, easily stowed in small spaces inflatable chairs, pads, and flotation devices all from a relatively simple combination of at least two inflatable drop stitch panels which can be held in position relative to each other by use of straps, or in other embodiments, by additional inflatable side panels which provide arms and support to hold the chair upright on the ground. Simple hinges can be used to connect the panels together in desired configurations, either as fixed deployments or as adjustable and convertible deployments, where in one deployment, the panels for a chair, and in another, a flat pad, which can be used as a float or as a ground pad for camping.

An inflatable sleeping pad or air mattress comprises an inflatable pad having a top layer and a bottom layer. At least one middle layer is disposed parallel to the top and bottom layers, and supported between the top layer and the bottom layer by a plurality of support baffles, wherein a first plurality of support baffles is disposed between the at least one middle layer and the top layer, and a second plurality of support baffles disposed between the at least middle one layer and the bottom layer. The sleeping pad further comprises an air inlet/outlet valve disposed on at least one of the inflatable pad top or bottom layers.

Multi-climate sleeping bags and methods of making the same are described. One sleeping bag may comprise a bottom panel comprising a head end and a foot end, wherein the bottom panel is formed from an inner shell, an outer shell, and an insulating material disposed between the inner shell and the outer shell, a first top panel comprising an inner shell, an outer shell, and an insulating material disposed between the inner shell and the outer shell, a first fastening mechanism configured to detachably couple an edge of the first top panel to an edge of the bottom panel, a second top panel comprising an inner shell, an outer shell, and an insulating material disposed between the inner shell and the outer shell, and a second fastening mechanism configured to detachably couple an edge of the second top panel to the edge of the bottom panel.

A quilt usable as a sleeping bag has inner and outer sets of fasteners arranged on slanted paths from each side edge to the bottom edge and fasteners along the bottom edge. The fasteners hold the quilt in a wrapped, overlapping arrangement. With the fasteners engaged, pulling a draw cord across the quilt bottom edge gathers the bottom edge and forms a closed, wrapped footbox of the sleeping bag. A sheet for use with a sleeping bag quilt include two sets of fasteners arranged to engage corresponding fasteners on the quilt to attach the quilt to the sheet in an expanded-footbox arrangement. Pulling a draw cord across the quilt bottom edge gathers the bottom edge and forms a closed, expanded footbox of the sleeping bag.
