CPC F16B 5/0685 (2013.01) [F16L 3/01 (2013.01); F16L 3/13 (2013.01)] | 18 Claims |
1. A stable, rotatably-adjustable mount for a fixture comprising:
a plastically-deformable, dome-shaped base having a convex, fixture-supporting topside portion and a concave, substrate-facing, underside portion opposite the topside portion, having a substrate-engaging portion defined by a circumferential edge;
a single screw with a non-circular head that resists twisting, said head rigidly embedded in a hub extending perpendicularly away from a center of the underside portion, said screw projecting perpendicularly away from the hub and having a pointed substrate-engaging tip and sharp threads to facilitate: (a) self-boring penetration of the substrate, (b) compression of the circumferential edge of the base against the substrate, and (c) a corresponding elastic deformation of the dome; and
a fixture attached to the fixture-supporting portion of the base; wherein said circumferential edge has protuberances uniformly spaced apart along the edge to provide additional friction between the edge and the substrate to prevent unintentional rotation of the base, and wherein the hub extends away from the center of the underside portion a distance less than a farthest extend of the protuberances.
