  • Patent number: 6012691
    Abstract: A simplified universal beam hanger suitable for concrete and steel beams, includes a pair of L-shape members each having notched vertical legs and horizontal legs. Adjustable spring clips fit on the notched vertical legs and project inwardly to bear on a portion of the beam. The clips have spread or angularly related spring legs and each has a hole which will telescope over the notched vertical leg only when each of the spring legs are pressed toward [a position] one another such that each of the spring legs are positioned generally normal to the vertical leg of the L-shape members. The clip has a bearing fulcrum which requires the load to be relieved before both legs of the clip can be pressed together and any vertical adjustment made. The horizontal legs of the L-shape members telescope into a housing beneath the beam and are maintained parallel and adjacent each other. The housing is formed from a single piece of sheet metal and has a clamp and confining windows at each end.

  • Patent number: 5713157
    Abstract: A deck hanger utilizes two sheet metal spring hanger clips to hook behind parallel accessible edges of a deck installation. Each clip has a body which includes a rectangular hole. A rectangular bar is positioned through the holes and U-shape blocking clip straddles each hanger clip body securing the bar in place. The bar spans a downwardly opening channel formed by the deck panels and supports cable trays, piping or other installations utilizing what might normally be dead space. Each clip also has a hook portion with a back having a barb and a nose portion no thicker than the sheet metal from which it is formed to enable grasping of the edges without distortion.
