Abstract

A work environment system, for product assembly, repair, storage and packaging, comprises a plurality of freestanding rigid rectangular frame modules (32) formed of vertical frame members (36) and upper and lower horizontal frame members (38, 40). The modules (32) can be securely connected together in end-to-end relationship at a number of angles by connectors (100) to form work stations (10,12,14,16,20,22) of various size and geometric configuration. The work stations (30) can be equipped with a variety of functional components to be utilized in product assembly, repair, storage and packaging, such functional components including work surfaces (242), shelves (244) and storage cabinets (246), all of which are connected to the freestanding modules (32). The work environment system further includes various transport carts (446) for transporting products and tools between work stations and which can be assembled substantially from the vertical and horizontal frame members (36,38,40) of the modules (32).
