Clamping mechanism for roller shutter, comprises unit contained in shutter guide profile which applies pressure against roller shutter strips when in resting state

摘要

Along and within the roller shutter guidance profile (1) a unit presses against strips of the roller shutter when it is in the resting state. The unit is a rotary component (2), its geometry designed to take up the play between itself and the strips, when turned. It is pre-loaded in this direction by a spring (4), which exerts constant pressure on the strips, when in the resting state. The pre-loading is removed by an actuator (5) when required. A sensor (6) detects operation of the roller shutter belt, and operates the actuator.
