SYSTEM COMPRISING A ROLLING SHUTTER TUBE AND A LATCH AND ROLLING SHUTTER INSTALLATION COMPRISING SUCH A SYSTEM

摘要

The invention relates to a system comprising a winding tube (4) of a rolling shutter (T) and a connection lock between the tube and the shutter, the latch comprising at least two articulated links (2a, 2b, 2c). , of which a first link (2a) is configured to be attached to an upper blade of the shutter and a last link (2c) is configured to be fixed on the outer radial surface (S4e) of the pipe (4), the last link ( 2c) and the tube (4) comprising shapes adapted to fit a first portion (2.1) of the last link on the outer radial surface (S4e) of the tube. The last link (2c) also comprises a second portion (2.2), whose radius of curvature (r2) in the non-deformed state is less than the maximum radius (r4) of the outer radial surface (S4e) of the tube, such that this second portion (2.2) is elastically deformed during assembly of the lock around the tube and is fixed by clamping around the tube.
