Title: Multi-purpose shelving - is made up from basic elements assembled together by butt-jointing
Inventor: BROCKMEIER JOHANNES
IPC: A47B91/00
Filed: 1974-08-13
Abstract: The unit shelving system comprises intersecting support plates and shelving panels which fit together like a screen so that the parts of these plates and panels which extend from the joint form a one-piece basic element with arms which are to be perpendicularly butt-jointed with the adjoining arms of the adjacent basic element. The arms of the basic element are at right angles to each other so that an L-shaped, T-shaped, +-shaped or flat element can be formed. The arms can be of the same length to each form half of a shelf panel or support panel but if the sections forming the supports are in two different lengths with a ratio of 2:3 a much more variable shelving system can be achieved. The connecting elements for butt-joining the different sections can be set inside the panels, e.g. in the form of dowels and slots.
