Abstract

The roller shutter for windows has interlocking slats (16 to 19) which connect the body (2) of the shutter to the winding drum (11). The slats slide telescopically into one another as the shutter reaches its fully lowered position, and will not pivot relative to one another until drawn apart by winding drum. The arrangement prevents partially lifting the shutter to gain unauthorised entry. The shutter has lateral guide rails (7) and a box (12) which houses the retracted shutter on the winding drum (11). The slats (16 to 19) may be an 'h' section with the upper leg (25) curling over (24) and forward at the top, and the lower frontal leg (33) bent inwards squarely (27) before curling up (30). The upper leg (23) of a slat lodges between the legs of the slat above and is of approx. equal height to these legs. The winding drum (11) may be notched (35, 36) to match the geometry of the locking blades.
