Abstract
In vertical lifting doors comprising an axle 11 with a wire drum 12 and a door spring 13, there is not in advance any protection which enters into operation if the spring fails. According to the invention, the door spring which stores energy for lifting of the door is pretensioned in such a way that if the spring fails a pawl engages in a ratchet wheel in order to jam the axle. In fixed connection with the axle 11 there is therefore a ratchet wheel 14, and stationary relative to the building in which the door is fitted there is a bracket plate 21, through which the axle 11 passes. The bracket plate 21 bears a pawl 22, which is actuated to engage with the ratchet wheel 14. The bracket plate 21 further bears an auxiliary plate 23, through which the axle 11 passes and which has a limited rotatability relative to the bracket plate 21 by virtue of being fastened to the bracket plate by a pair of bolts 24 passing through a pair of long holes 26 in the bracket plate 21. The auxiliary plate 23 is held pretensioned by the door spring 13 in a position in which the pawl 22 is held disengaged from the ratchet wheel 14 in the normal situation. <IMAGE>
