Abstract

The "end of run" stop-mechanism for roller blinds may be used on motorised or manually operated blinds, and automatically arrest, rotation of the winding drum (2) when the blind (1) is fully extendend. The drum (1) is hollow and houses a freely mounted lever (10) with an intermediate fulcrum (9). The movement of the lever (10) is initially restricted by the presence of the blind (1) wrapped round the drum (2). When the blind (1) is fully unwound the lever (10) pivots under gravity to either lock the drum (2) against further rotations or to actuate a motor switch. The lever (10) may be mounted in the hub (3) of the drum (2), be of a 'Z' shape, and align approx. parallel to the long axis of the drum. When the blind (1) is fully unwound the toe (13) of the lever (10) passes through a now unrestricted opening (14) in the drum (2) wall. The lever (10), thus, rotates and the heel (12) enters a slot (17) in the drive shaft (6, 16) locking it against rotation.
