FRAME EDGE FLANGE AND SEALING STRIP THEREFOR

摘要

A flange (18) has projections (16) which engage lips (14) on a sealing strip (2) to attach the strip (2) to the flange (18). The strip (2) has two side portions (10) extending from a base (4) and the lips (14) are formed on the inner surface of the side portions (10). The free edge (20) of the flange (18) presses against a diaphragm (6) spaced by a void (8) from the base (4). As a result, the pressure of the diaphragm (6) on the flange (18) forces the projections (16) into abutment with the lips (14). As a result, the flange (18) and the strip (2) are securely connected so that a considerable force is required to remove the strip (2) from the flange (18) thereby preventing accidental separation. A tubular member (12) may be attached to one of the side portions (10) against which abuts an object being sealed to the flange.
