Roller shutter universal guide rail - with connecting U-sectioned lug and notching projection on cross arms for rail cutout

摘要

The run-in funnel of plastic is for U-sectioned guide-rails on roller shutter mountings. Crossarms face the shutter guide channel, and can be sent onto the guide-rail from above. The two side crossarms (17) facing the guide-rail are connected by a transverse crossarm (18), facing away from the roller shutter slats (10), to a U-sectioned lug (3) of the same breadth as the guide-rail. The surfaces of the side crossarms facing the guide-rail are fitted with one or more notching projections (11), protruding at the top while the bottom area lies in the plane of these surfaces. This engages in one or more matching cutouts in the sidewalls of the guide-rail. Non-wearing plastic is a suitable material for the run-in funnel.
