  • Patent number: 8950021
    Abstract: A retractable bunk or bed is disclosed. The retractable bunk can be used in a sleeper compartment so as to optimize space within the cab. The innovation can include a shaft around which a suitably strong, yet flexible, material bunk can be wound. Thus, in a closed or “hidden” state, the material can be rolled up around the shaft and stowed, for example behind a door or within a compartment as desired. In an open position, the material is extended in a horizontal manner and affixed to retain the “bunk” position.

  • Patent number: 7779491
    Abstract: A convertible support apparatus for supporting an object over a ground surface is convertible between an operating configuration and a storage configuration. The support apparatus may comprise side members, a support area configured to connect to the side members, and a bow truss configured to bow. When the device is assembled in the operating configuration, both the support area and the bow truss are connected between the side members and the bow truss is configured to bow and place the support area under tension. The bow truss may comprise a bow tube connected between two foot fixtures. In one embodiment, when the apparatus is supporting a sufficiently heavy object, the bow tube will bow and contact the ground surface and provide additional support to the apparatus.

  • Patent number: 7086100
    Abstract: A joining assembly for a child's bed is provided. A child's bed according to the invention mainly contains a mesh structure, bedposts, and supporting rods embedded in the four rim of the rectangular mesh structure. By installing the supporting rods into the positioning holes on the bedposts, the mesh structure is expanded to a flat surface for a child to sleep or play on it. Each of the four corners of the mesh structure has a hook attached to it respectively. The hook is hooked to the rim of a positioning plate of the bedpost so that there is no gap left between the bedposts and the mesh structure.

  • Patent number: 7051385
    Abstract: A portable, suspendable cot used in rock climbing and the like includes a collapsible frame supporting a webbing therebetween. The frame includes linkages that pivot from a parallel orientation in a closed position to an orthogonal angle (for rectangular frames) or an acute angle (for trapezoidal frames) in an open position. The linkages further comprise couplings that complete the framework and use gravitational forces to enhance the linkages, forming a secure platform that resists warping. Cabling connects the respective linkages and supports the frame so as to be suspendable from a central apex vertically displaced from the frame. The cabling can pass through a free end of the pivoting links to guide the free end to the coupling, and preserve a closed loop for the respective elements of the frame.

  • Patent number: 6907629
    Abstract: A tabletop useful for accurate positioning of a patient for imaging and diagnosis, so that patient positioning in subsequent medical treatments, such as radiation therapy, accurately and precisely correlates with the imaging data. The tabletop of the present invention is a solid flat tabletop adapted to fit over or as an insert in a conventional CT imaging or scan table and provides a flexible support section in which the flexible support material is tensioned to provide a vertical deflection corresponding to the vertical deflection of a flexible patient support of a treatment simulator or linear accelerator. In a preferred embodiment, the flexible support section may be removed and inserted into the treatment table to provide an exact correlation in vertical deflection during treatment.

  • Patent number: 6564400
    Abstract: The present invention provides a cot assembly that includes a frame, supporting corner pieces and bedding material. The frame is preferably of a one or two piece construction and is shaped into a perimeter defining an interior area. Corner pieces support the frame above an external support surface. The bedding material extends across the interior of the frame and into the corner pieces without any gaps between the material, the frame and corner pieces, thereby protecting against injury which could otherwise result from the presence of such gaps. The continuous frame maintains the cot's rigidity while the corner pieces lower the cot's profile for stacking. The cot includes at least a number of corner pieces corresponding to the corners of the polygonal shape. A pedestal extends downwardly from each corner piece to engage the floor or other supporting surface.
