摘要

The metal framework for shelves consists of uprights (1) and crosspieces (5) which interlock without the use of fixtures. The uprights are U or C shaped in cross-section and have, on the middle surface, two rows of trapezoidal slots (2) arranged on two vertical, parallel lines. The crosspieces (5) have L-shaped ends (3) on one surface of which are inward projecting catches (4). These fit into the level or alternately staggered slots (2) on the uprights. The ends (3) are soldered onto the crosspieces which are made of hollow rectangular sections.
