  • Patent number: 4398691
    Abstract: A wall bracket consists of a hoop-like part with hollow cavities in its two ends which can be slipped over male supporting parts fixed to a wall. Possible malalignment and positional inaccuracy of the supporting parts is catered for by a construction in which each supporting part consists of a base part and a head part which are secured to the wall by a central fixing screw passing through large clearance holes in the base and head part to accommodate positional inaccuracies. In addition the mating end faces of the base and headparts are of complementary part spherical form so that the head part can be angled relative to the base part to compensate for malalignment.
