  • Patent number: 5815992
    Abstract: A two part, weight bearing shim adjustable in height. The shim comprises two generally triangular or wedge shaped members. A base member has a flat bottom surface and a stepped upper surface. A smaller member is placed in inverted relationship on the base member. The smaller member has a stepped lower surface cooperating with the stepped upper surface of the base member. The upper surface of the smaller member is parallel to the bottom surface of the base member after assembly. The base and smaller members are mutually keyed to prevent improper interfit during assembly. The base member has vertical voids or bores formed in its body. This construction promotes ability of the bottom surface to engage a rough or irregular environmental surface, and minimizes the amount of constituent material required for fabrication. Recycled plastic is a preferred constituent material.

  • Patent number: 5697586
    Abstract: An assembly to mount an appliance on a floor includes a pair of openings in the appliance base, each surrounded by a helical thread. The thread includes a pair of downwardly projecting detents. A mount for each opening includes a head with a shaft extending from the top thereof and received in the opening. The shaft includes an external helical thread mating with the appliance base thread. The mount is made of plastic which cold flows sufficiently for the shaft thread to conform to the detents. An unbalance responsive mechanism includes a strap extending across the housing with a transverse pin adjacent each end. A mount for each end of the strap includes a head with a shaft extending from the top thereof. The distal end of the shaft includes transverse openings to receive an end portion of the strap and the corresponding transverse pin. Non-skid, insulating pads are bonded to the bottom of the heads.

  • Patent number: 5564662
    Abstract: A floor lock system for supporting a surgery table having a patient support surface supported by a base member and defining a longitudinal axis. The system includes first and second primary lock members located on laterally opposite sides of the longitudinal axis for the base member. A third primary lock member is located generally along the longitudinal axis and the first and second secondary lock members are located on laterally opposite sides of the longitudinal axis. The primary lock members are actuated by first actuators for movement toward a floor surface with a first force and the secondary lock members are actuated by second actuators for movement toward the floor surface with a second force less than the first force.

  • Patent number: 5503082
    Abstract: A concrete-embedded, machinery-anchoring floor system includes parallel, accurately-extruded steel rails each having a unique cross-sectional configuration. Vertical loading of the rails improves the load-bearing strength of the concrete, whether the loading is in tension or compression. Each rail includes a pair of spaced angularly-extending, outwardly and downwardly-projecting flanges. When a downward compressive load is applied through the rails from above, the load also applies downward and inward force vectors generally perpendicular to the angular flanges, compressing concrete therebetween. If tension is applied to a rail from a cantilevered load, the angular flanges are fulcrumed toward each other about their connecting joints with the rail, also compressing and strengthening concrete therebetween. The angular flanges are rounded at their distal edges to enable supporting and interconnecting reinforcing bars to be easily welded to the rounded edges, irrespective of the angle of the bars to the edges.
