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.

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.

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.

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.

Abstract: An umbrella that when folded functions as a conventional flashlight, and when opened functions as an umbrella with a two-way flashlight handle. The flashlight handle contains two lamps/reflectors. One is located in the side of the umbrella handle. The other is positioned in the base of the handle. The handle also serves as a battery compartment for a plurality of "AA" size batteries. The lamp/reflector at the base of said handle is intended to produce the illuminating power of a conventional flashlight. The lamp/reflector at the side of said handle is intended to provide illumination for the forward path of the umbrella user when the umbrella is fully extended. The side lamp/reflector is positioned to direct light onto the forward path of the user when the handle is held vertically. Either lamp may be activated at a time via a two-way switch, located on side of said handle, when said umbrella is either folded or fully extended.

Abstract: A golf bag umbrella attached to the side of a golf bag for protecting the open end of the bag and golf clubs therein from the elements. The umbrella includes an articulated shaft, pivoted and locked by a button latch located above a lower end handle grip on the shaft. The umbrella ribs may be overbuilt to provide a strengthened umbrella that resists being everted in a moderate to strong wind. The umbrella may be removed and pivoted against the ground by a single hand of the user. The umbrella is readily attached to and removed from the bag by use of a pair of spring clips or clamps. During play in inclement weather, the golfer may use the umbrella conventionally, to protect himself, and then clip the open umbrella onto the bag, to protect the bag while taking a shot or stroke, and then readily detach the umbrella from the bag for protection, as the golfer walks to the ball to take another stroke.

Abstract: An umbrella includes a substantially inextensible cord which is mounted by couplers to the free ends of the ribs of the umbrella such that the cord forms a closed loop disposed radially inwardly of the ribs of the umbrella. The cord braces the umbrella against inversion, and the couplers can be designed to allow the cord to be retrofitted to an existing umbrella.

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.
