Abstract
A clean environment enclosure assembly (10) prevents contaminants from reaching unfinished products during the manufacturing process. The clean environment enclosure assembly (10) includes a plurality of frames (16) which are secured to each other using various shaped brackets (60, 62, 64) to form a structural frame. Sheets of plastic (22) extend across each of the plurality of frames (16) to complete the housing (14). The sheets of plastic (22) are secured to side members (18) of the frames (16) by elongated caps (24) which run the length of the side members (18). The caps (24) have two arms (30, 32) which engage the two substantially parallel side walls (42) of the side members (18) wherein detents (38,40) of the two arms (30, 32) engage indents (44, 46) of the parallel side walls (42) preventing the cap (24) from freely disengaging the side member (18). The sheets of plastic (22) are sandwiched between the cap (24) and the side members (18).
