ABSTRACT:
A beam construction for supporting shelves, cabinets and like units between upright wooden beams. The connection comprises a single support element at each end of a unit to be supported having two vertically superposed hooks at one end for hooking into a single rail in the beam, and a single upward projection at the other end for hooking into an aperture in the bottom of the unit to be supported. A vertical slot in said unit hides the corresponding vertical portion of the support element so that the support structure is invisible during normal inspection. Despite the single point support feature, the units are secure against tipping and against damage during assembly and disassembly.
