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.

A sleeping bag extends from a lower end to an entrance end and includes first and second halves arranged in opposing relationship with one another to define a sleeping compartment therebetween. A draw cord extends circumferentially through the first and second halves in spaced relationship with the entrance end to define a collar portion of the sleeping bag disposed between the entrance end and the draw cord. The draw cord is adjustable to vary an opening defined by the collar portion for permitting the collar portion to be adjusted around a neck of a user of the sleeping bag assembly. Additional thermal protection for the sleeping bag is achieved by the incorporation of the collar portion with a unique internal adjustment mechanism that permits the circumference of the opening of the collar portion to be changed while at the same time maintaining insulation thickness.

A sleeping bag, components thereof, and associated methods. The sleeping bad includes a bag body sized and shaped to receive a human lying down in a human-receiving interior of the bag body. The sleeping bag includes a left flap and right flap releasably connected to the bag body. The left flap and right flap are movable with respect to the bag body into overlapping and underlapping configurations to provide insulation and/or cushioning. The left flap and right flap are releasably connectable to the bag body.

An all-inclusive electrical heating liner for use in the fabrication of articles of different sizes requiring to be heated is disclosed. It is comprised of a thermally insulating fabric piece which is shaped to define two or more panels to which are secured patterns of heating wires at specific locations. The spaced relationship between the two or more panels is adjustable whereby the liner can be incorporated in articles of different sizes. The adjustments are made by adjustable band sections provided with delineated line formations permitting specific pleating and securement and wherein a wire interconnecting the patterns of heating wires detachably extends across the delineated line formations. The liner incorporates a power supply, controls, switches, wiring, connectors and other components thereby facilitating the incorporation of the liner into an article of different sizes resulting in a cost reduction to the manufacturer of such heated articles. Various embodiments are described to show that the all-inclusive one-piece heating liner is adaptable to many articles, such as pants sleeping bags and bags which require control heating.

A thermal insulating structure having insulation channels formed therein to receive insulation material, a movement channel extending along the insulation channels to disburse the insulation between the insulation channels and a storage channel to store insulation material not being used in the insulation channels. The movement channel, insulation channels and storage channel being integrally formed with each other while being partially obstructed from each other to maintain insulating material in the desired channels until moved to another one of the channels by a swiping or patting motion on the structure to provide a widely ranging temperature adjustable structure such as a sleeping bag, jacket, or comforter.

A sleeping bag includes a top cover and bottom sheet. The bottom sheet can be secured to a sleeping pad and includes a sheet portion and lateral flaps connected to the sheet portion along opposite lateral edges of the sleeping pad when the bottom sheet is secured thereto. The top cover and lateral flaps enable attachment, detachment, and reattachment of the lateral flaps along their lateral edges to a top cover outer surface along corresponding attachment paths displaced medially from top cover lateral edges, enabling a top cover headward portion to assume wrapped and expanded configurations, and enabling conversion between those configurations. When wrapped, headward portions of the top cover outer surface, that are lateral of the attachment paths, are positioned against the sheet portion; when expanded, the lateral flaps and lateral portions of the top cover extend upward or laterally away from the sleeping pad lateral edges.

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 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.

A sleeping bag includes a top cover and bottom sheet. The bottom sheet can be secured to a sleeping pad and includes a sheet portion and lateral flaps connected to the sheet portion along opposite lateral edges of the sleeping pad when the bottom sheet is secured thereto. The top cover and lateral flaps enable attachment, detachment, and reattachment of the lateral flaps along their lateral edges to a top cover outer surface along corresponding attachment paths displaced medially from top cover lateral edges, enabling a top cover headward portion to assume wrapped and expanded configurations, and enabling conversion between those configurations. When wrapped, headward portions of the top cover outer surface, that are lateral of the attachment paths, are positioned against the sheet portion; when expanded, the lateral flaps and lateral portions of the top cover extend upward or laterally away from the sleeping pad lateral edges.

An all-inclusive electrical heating liner for use in the fabrication of articles of apparel is disclosed. It is comprised of a thermally insulating fabric piece which is shaped to define a dorsal panel and a pair of frontal panels to which are secured patterns of heating wires at specific locations. The spaced relationship between the dorsal panel and the pair of frontal panels is adjustable whereby the liner can be incorporated in articles of apparel of different sizes including small. Medium, large and X-large apparel sizes and gender types. The liner incorporates a power supply, controls, switches, wiring, connectors and other components thereby facilitating the incorporation of the liner into an article of apparel resulting in a cost reduction to the manufacturer of heated articles of apparel. Various embodiments are described to show that the all-inclusive one-piece heating liner is adaptable to many articles which require control heating.
