摘要：
The present invention is directed toward portable visible light beam pointing devices for set out, marking, and other handyman purposes, and thumb pressure mounted fixtures fashioned as hooks, hook racks, wall mounts, and the like. The pointing devices include a light beam generator, and a pair of orthogonal bubble vials for indicating the orientation of the pointing device along orthogonal axes in a horizontal plane. The thumb pressure mounted fixtures have a body member and at least one thumb tack-like member with a central portion having a steel spike transversely directed relative to the body member for driving into a supporting surface. The thumb tack-like members are intended to be manually collapsible from an arc shaped inoperative configuration with a concealed spike to a generally M-shaped operative configuration with an exposed spike for driving into a supporting surface.
