Abstract: A space divider system for subdividing an interior space into distinct work areas is disclosed. The space divider system makes use of modular wall panels having improved interconnection components adapted to interact with tubular mounting frames which are interconnected intermediate to adjacent wall panels. Each wall panel includes a spring-biased upper bracket and a lower bracket each of which is mounted to a respective upper and lower horizontal surface at each corner of the wall panel. The lower bracket has an upturned lip which captures the lower open end of the mounting frame. The upper bracket is normally biased in an open position to permit the mounting frame to be aligned against the wall panel and is thereafter moved downward until its downturned lip captures the open upper end of the mounting frame. Pre-assembly of the upper bracket on each wall panel permits a method of easy and quick assembly and disassembly of the wall panels.
