  • Patent number: 10458145
    Abstract: A frame joint connects a plurality of elongate frame members adapted to support a flexible shelter skin. The frame joint includes a first housing having an interior and frame connectors. Each frame connector is adapted to releasably connect an elongate frame member to the first housing. The frame joint includes an electrical source mounted in the interior of the first housing. A light emitting element mounted on the first housing and connected to the electrical source emits light to illuminate an interior of the shelter. The light emitting element is positioned on the first housing to direct light toward the interior of the shelter when the joint is connected to the elongate frame members and the frame members are supporting the flexible shelter skin. The frame joint includes a switch operatively connected to the electrical source and the light emitting element for selectively energizing the light emitting element.

    Abstract: A frame joint connects a plurality of elongate frame members adapted to support a flexible shelter skin. The frame joint includes a first housing having an interior and frame connectors. Each frame connector is adapted to releasably connect the joint to at least two elongate frame members. The frame joint includes an electrical source mounted in the interior of the first housing. A light emitting element mounted on the first housing and connected to the electrical source emits light to illuminate an interior of the shelter. The light emitting element is positioned on the first housing to direct light toward the interior of the shelter when the joint is connected to the elongate frame members and the frame members are supporting the flexible shelter skin.

  • Publication number: 20020074834
    Abstract: A collapsible chair (10), having a frame assembly (12) including a number of angled frame members (24). The upper ends of the angled frame members (24) are pivotally attached to upper connectors (64), and the lower ends are pivotally attached to feet (20). The frame assembly (12) as a whole is configured to expand outwardly from a central area (58). The frame assembly (12) further includes back support uprights (34) and rear corner upright members (32). Each of the upright members (32) has an upper end which is pivotally connected to one of said back support uprights (34) at a flexible joint (48). The chair (10) also includes a support surface (16), having a back portion (38) which is held in position by the back support uprights (34). The flexible joint (48) includes a resilient support assembly (30) which biases the back portion (38) to an upright position.

  • Patent number: 6398297
    Abstract: A collapsible rocking chair (1), which collapses to a compact bundle, including a chair part (2) having a number of support frame members (F1-10) which are pivotally connected to connecting members (6), and a rocking part (4) including a pair of rocker members (38) and shoe members (26) which are fixed to the rocker members (38). The shoe members (26) are detachably connected to the connecting members (6) to form locking assemblies (50). The shoe member (26) include a housing (72), a receptacle (36) which receives the connecting member (6), and a retaining element (64) including at least one rotary element (66) which is rotatably mounted to the shoe member housing (72). The rotary element (66) rotates to engage a retaining slot (60) of the connecting member (6), thereby locking it in place. A second embodiment includes an alternate locking assembly (86). The shoe members (26) each include a housing (72), and a retaining element (64) including a retaining tab (98) and flanges (94), which surround a slot (96).

  • Patent number: 5421355
    Abstract: A tent assembly capable of assuming multiple configurations includes a shell having side walls made of flexible material in which at least a portion of the flexible material is water vapor permeable, a fly of flexible water impermeable material and a frame to support the shell in a first erect configuration in which the shell substantially encloses a space sized to accommodate one or more occupants and the shell is not covered by the fly. The frame is further capable of supporting the shell and fly in a second erect configuration in which the shell encloses a space sized to accommodate one or more occupants and the fly canopies the shell to prevent substantial moisture from falling on the shell. Moreover, the frame is capable of supporting the fly in a third erect configuration in which the fly is suspended over and shelters a space sized to accommodate one or more occupants.
