  • Patent number: 8689514
    Abstract: An expandable structure formed from a single piece of material is moveable between a stowed position and an extended position. The structure has a base and a plurality of support members integral with the base that move between a stowed position and an extended position. In the stowed position, the base and the plurality of support members are essentially a two dimensional shape. A biasing force makes the structure self-erecting and moves it to the extended position. In the extended position, the expandable structure has a hollow interior and a cross-section that is bounded by a closed path.

  • Patent number: 8677716
    Abstract: A framing member incorporates a series of web slots along a portion of the member that are expanded through the process of manufacture. The expansion of the web slots creates voids and metal web elements in the webbed portion of the member, which can be a stud. The voids created during the expansion process can become the voids for running wiring, plumbing and heating ducts. The web elements can be designed to minimize thermal transmission from the exterior to the interior of a wall including the member, as well as provide adequate structure properties required from the structural member. The expanded slots allow the part to enlarge without increasing the amount of raw material and therefore substantially reducing the cost to manufacture.

  • Patent number: 8084117
    Abstract: Expandable surfaces made from sheet materials with slits distributed on the surface of sheet material where the surfaces expand by application of force along or/and across the surface of sheet material. The unexpanded surfaces are flat sheets, or closed surfaces like cylinders, spheres, tubes, or custom-designed organic shapes marked with pre-formed or post-formed slit designs. The expanded surfaces can be single units or modules which can be attached to one another through various means. The sheet materials range from hard surfaces like metals, to softer materials like papers and plastics, or pliable materials like fabrics, rubbers, synthetic surfaces or bio-surfaces. The slits are arranged in patterns ranging from periodic, non-periodic to irregular designs. The slits can be straight, bent, curved or irregularly shaped with even or uneven spacing. Slitting can be achieved by digital cutting or punching devices like laser-cutting, water-jet cutting, digital punching, automated dies, etc.

  • Publication number: 20110247296
    Abstract: The present invention provides a cold formed joist that can be used in a variety of construction applications. The present cold formed joist consists of three elements, each formed from sheet metal: an upper chord, an intermediate web, and a lower web. These three elements can be produced in different dimensions. The upper chord further consists of a downwardly facing receiving channel adapted to receive the upper edge of the intermediate web, and two upwardly facing channels. The lower chord consists of an upwardly facing receiving channel that is adapted to receive the lower edge of the intermediate web.

  • Patent number: 7803466
    Abstract: An expandable panel includes a generally planar panel portion, penetrated by several pluralities of spaced parallel cuts. The cuts include aligned sets of apertures and aligned sets of transverse gaps. The panel is expandable by pulling the sides apart, separating the panel along the cuts. The positioning of the apertures and gaps causes the panel portions defined between the parallel cuts to bend apart, defining front and back planes, to which sheathing, surface panels, or “skins,” can be attached. The panel can be locked in its open position by inserting connectors in adjacent aligned gaps.
