  • Patent number: 5311712
    Abstract: The present inventive building and the construction method thereof uses a joined-and-filled-in-situ casing system from which to provide the foundation, exterior walls and interior walls of a structure using materials that are high strength, extremely durable, highly insulating and fire-retardant. The present inventive building and the construction method thereof provides a solution to the excessive wastes generated during conventional construction methods by utilizing construction materials that are recycled by being shredded and used as insulating fill. The present inventive building and construction method thereof incorporates an improved electrical wiring system that is particularly suited to the above casing system. The inventive wiring system provides an improved gang-box and wire conduit means that is much easier to install than convention wiring methods. Live wires are encapsulated in a substantially fire-proof medium, and the location of wiring within walls is consistent and hence predictable.

  • Patent number: 5301705
    Abstract: A collapsible shade structure includes a plurality of foldable frame members each having a folded and an unfolded orientation. A fabric material is provided for substantially covering the frame members to form a side panel for each frame member, each side panel assuming the unfolded orientation of its associated frame member. Interconnecting portions of the fabric material form a hinge portion between each frame member. The structure may be folded and stored by folding the side panels and their corresponding frame members on top of each other about the hinge portions to have the side panels and frame members overlying each other. The overlaying side panels and frame members are then collapsed by twisting and folding to form a plurality of concentric frame members and side panels to substantially reduce the size of the shade structure.

  • Patent number: 5291717
    Abstract: A method and resulting wood frame that can be used to construct a wall. To create a curved wall, lines are scribed onto the floor to define the wall radius. The wood frame is constructed by first arranging a plurality of studs in a spaced apart arrangement. The studs have first and second surfaces along the longitudinal axis, which terminate at first and second ends that have bottom and top surfaces respectively. A flexible flat member is then attached to the first end of the studs. The flexible member has a base portion which is nailed to the first surface of the studs and a plurality of spaced apart tabs. Some of the tabs are immediately adjacent the bottom of the studs, while other tabs are located between the spaced apart studs. The attached studs are then lifted into place and the flexible member is bent until the curved member follows the scribed outline. The frame is then nailed to the floor through the tabs that are located between the studs.

  • Patent number: 5282486
    Abstract: A novel form of crutch is provided which can be used, particularly by paraplegics, to move between sitting and standing positions. The crutch includes a unique foot mechanism which gives added stability to the user of a pair of the crutches during such sitting/standing transitions, and which can be retracted so as to avoid interference with normal crutch-aided walking. A set of such powered crutches, incorporating both power extension/retraction and power foot adjustment, are capable of extended powered operation with on-board electrical power, and use power only for adjustment and are self-locking into adjusted positions. The power assist of the crutches are controllable from switches strategically located by the crutch handles so the user can manipulate the control switches without releasing his/her hold on the crutch handles. Also disclosed is a unique method of assisting disabled persons, using such crutches, to move between seated and standing positions without further assistance.

  • Patent number: 5275187
    Abstract: A foldable walker that includes a single latch operator connected with each of left and right latches for the walker's left and right side frames, the left and right latches functioning to latch the left and right side frames open in the use position. Use of the single operator by only one of the user's hands allows both the left and right latches to unlatch the side frames from their open or use position, thereby allowing both those side frames to pivot closed into a collapsed or storage position against the front frame. In preferred form, the left and right latches also function to latch the left and right side frames closed in the storage position. In that preferred form, use of the single operator again by only one of the user's hands allows both the left and right latches to unlatch the side frames from their storage position, thereby allowing both the left and right side frames to pivot back open into the use position relative to the front frame.
