Abstract

A clean box in which the rubber arms and hands may slide laterally relative to the remainder of the box. A first rigid plastic sheet has ovals passing through it. A second rigid plastic sheet, in front of the first, has circular openings on which the rubberized arm and hand gloves attach. The circular openings' diameter approximately equals the smaller dimension of the ovals on the first sheet of plastic. Resin strips provide an air seal along the upper and lower edges of the sliding first sheet of plastic. Wiper blades attached to the edges of the moving sheet complete the seal between the two sheets of plastic. A worker, with his hands and arms in the gloves and needing to reach a distant point in the clean box, may simply push against the edge of the openings for the gloves. The sheet of plastic will then move in the direction in which pushed. The clean box may have entirely rigid transparent sides to allow for a clear view. Angling the portion of the clean box above the arm openings provides a surface which will not likely reflect ambient light into the worker's eyes.
