Universally adjustable housing apparatus

Claim 1

Apparatus comprising a hollow housing having a top wall, a front wall, a bottom wall and side-walls and adapted for containing a device having a functional axis, a socket means for supporting said housing for universal adjustment and locking means for securing the housing and socket means in adjusted position comprising a fastener bolt with a nut threaded thereon, at least one of said walls other than the front wall being planar, said one planar wall and said socket means having respective mating surfaces in the form of spherical segments, the mating surface on the housing being convex outwards and the mating surface on the socket means being concave inwards, said fastener bolt protruding centrally from the convex mating surface at right angles thereto, the concave mating surface having a circular opening the periphery of which is concentric with the periphery of the respective spherical segment surface, said fastener bolt passing with radial clearance through said concentric opening to enable adjustment of the relative position of the housing and socket means in equal extent in all directions, and retaining means larger in diameter than said concentric opening bearing in locked position against the back surface of the socket means at said concentric opening, said housing including at least one outwardly projecting protrusion having a free edge extending beyond the vertex of the convex mating surface on the housing for alternative stable mounting of the housing on a base.
