An up-and-over garage door comprises a leaf 14 mounted so as to be capable of pivoting. In order to operate the leaf, there is provision for using a transmission mechanism equipped with a stop 34 which comes into engagement with a bearing element placed level with the upper edge of the leaf. To provide an emergency release, the bearing element is designed so as to be capable of being displaced, in such a way that its displacement allows it to disengage from the stop of the transmission mechanism. <IMAGE> |
