Spring clip fastener for holding fly screen frame to support frame, comprises helical spring sliding in hollow extrusion, with projecting end section to grip support frame

摘要

The helical spring (12) is introduced into a hollow chamber (4) which runs through the length of the extruded frame profile (2). Its axis (16) lies transversely with respect to the chamber length. The end of the spring transitions into a long arm (20) which emerges from a groove (18) in the chamber (20), in which it can slide. The tip of the arm is bent to form a projection (34) which grips the support frame (30). The other end of the spring transitions into a supporting arm (36) which is accommodated within the hollow chamber.
