Roller shutter case bottom - has angular hard plastics sealing profile co-extruded with soft plastics sealing elements on vertical arm surface

摘要

As applied for closing the joint gap between the bottom of a case holding a rolled-up shutter sheet and the end face of the top bar of the piece of window case concerned, the sealing profile unit has a body which is angular in cross-section, comprising a horizontal and a vertical shank. One or more yielding elastic sealing elements (13, 14) are fitted to the surface of the vertical shank (12) furthest from the angle, running continuously parallel to the longitudinal line of the profile body (10). There are pref. at least two such elements, aligned parallel at a vertical inteval, the bottom one being in the form of a wedge-shaped sealing lipe (13), tapering away from the vertical shank. These maybe made of soft PVC, and the main body of hard PVC.
