Because the base element is rigidly attached to the substrate-penetrating element, a force applied to the Mount parallel to the plane of the substrate is offset by the pressure of the perimeter of the base element against the substrate, resulting in additional strength. The Mount's single-screw, self-boring element allows quick and easy installation. The spring-like base-element permits 360-degree rotation of the Mount while maintaining uniform pressure against the substrate, thereby preserving strength regardless of rotational positioning. The mount remains economical in relation to mounts of similar strength and rotational adjustability due to its insert-molded construction. ## Claims ### Claim 1 A stable, rotatably-adjustable mount for a fixture, comprising: a plastically-deformable, domeshaped 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, wherein the dome shaped base is a section of a hollow sphere cut by a plane; a single screw with a non-circular head that resists twisting, said head rigidly embedded in a conical hub extending perpendicularly away from a center of the underside portion, said screw projecting perpendicularly away from the conical 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 hub includes a bottom portion having a flat surface that acts as a stop to limit deformation of the wall of the hub. ### Claim 2 (depends on 1) The device of claim 1, 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. ### Claim 3 A device for securely and rotatably holding a first object on a surface of a second object, comprising: a deformable hollow base having a wall defining a dome shape, the wall having a lower circumferential edge for engaging a substantially flat surface of the second object, wherein the dome shape is a section of a sphere cut by a plane; and a single screw extending lengthwise from a top of the dome-shaped base along an axis perpendicular to a plane defined by the lower circumferential edge of the dome shaped base, wherein the base is comprised of a thermoplastic material and a non-circular head of the screw is embedded in the thermoplastic material of the base. ### Claim at position 4 4-5. (canceled) ### Claim 6 (depends on 3) The device of claim 3, in which a countersunk hole is defined at the top of the dome-shaped base and the screw includes a shank that extends through the hole and a head seated in a countersink of the hole. ### Claim 7 (depends on 3) The device of claim 3, in which the dome-shaped base is comprised of a polyolefin. ### Claim 8 (depends on 7) The device of claim 7, in which the polyolefin is polypropylene. ### Claim 9 (depends on 3) The device of claim 3, in which a plurality of nubs are defined on the lower circumferential edge of the wall of the dome-shaped base. ### Claim 10 (canceled) ### Claim 11 (depends on 3) The device of claim 3, in which the dome shape is a section of an ellipsoid cut by a plane perpendicular to a major or minor axis of the ellipsoid. ### Claim 12 (depends on 3) The device of claim 3, in which the screw has a thread density of at least 10 threads per inch. ### Claim 13 (depends on 3) The device of claim 3, in which the screw has a thread density of at least 16 threads per inch. ### Claim 14 (depends on 3) The device of claim 3, in which the screw has a tapered shank. ### Claim 15 (depends on 12) The device of claim 12, in which the screw is self-tapping. ### Claim 16 (depends on 12) The device of claim 12, in which the screw is self-drilling. ### Claim 17 (depends on 3) The device of claim 3, in which a length ratio of the width of the base to the height of the base is from 4 to 8. ### Claim 18 (depends on 3) The device of claim 3, in which a length ratio of the width of the base to the height of the base is about 6. ### Claim 19 (depends on 3) The device of claim 3, in which the base includes a hub portion extending from the top of the base toward a plane defined by the lower circumferential edge of the wall of the base, the bottom of the hub having a flat surface that acts as a stop to limit deformation of the wall of the hub. ### Claim 20 (depends on 1) The device of claim 1, in which the diameter of the base is from 1.5 to 2.5 inches and the length of the screw is from 0.5 to 1.5 inches.
