Abstract (en)
A spring break protection mechanism for a sectional door comprising a base plate (2) with a pawl (3) pivotably connected thereto, which is coupled to an input member (5) for cooperation with a balancing spring. The spring break protection mechanism further comprises a ratchet wheel (6) for cooperation with a balancing axle. The pawl (3) is pivotable between a first position, in which the ratchet wheel (6) is free-running, and a second position in which the pawl (3) blocks the ratchet wheel (6). The pawl (3) is biased by an operating spring (7) to the second position against the force of the balancing spring. The spring break protection mechanism is characterized in that the pawl (3) is provided with a crumple zone (12) which, with the pawl (3) in the second position, plastically deforms from a predetermined threshold value of a blocking force.
