  • Patent number: 5224805
    Abstract: An anchoring plug made from a hard-elastic plastic material having a closed shank part 1 and two mutually opposite spreading fingers 2 and 3. A screw hole 10, extends through the shank part 1 down into a central space 12 between the spreading fingers for receipt of a screw 18. To be able to drive the plug directly into gypsum board without having to first drill a hole, one spreading finger 2 is longer than the other spreading finger and has a hook-shaped tip 4 forming a recess 5 at its free end. Initially the end of the shorter spreading finger 3 nests in this recess to provide a pointed end to the plug, but springs free of the recess when a screw is screwed into the plug.

  • Patent number: 4478381
    Abstract: An elastic pipe clamp having a lower yoke, a fastener foot or the like for anchoring the lower yoke to a fixed surface and a cooperating upper yoke, the pipe being securely held between the yokes when they are locked together in a positive manner. A hinge-band pivotally connects one end of the upper yoke to one end of the lower yoke and mutually engaging locking hooks are provided on the opposite ends of the yoke from the hinge band for locking the yokes together. At least two (2) beaks on the hinged end of one of the yokes curve inwardly with respect to and over the hinge-band, the beaks being adjacent to the outer edges of the yoke with their outer arcs being tangent to the inside wall of the yoke. Cooperating recesses are provided in the other yoke that are open on their outer sides and have upper and lower walls with a radius curvature similar to the curvature of the beaks, whereby the beaks substantially fill the recesses when the clamp is closed.
