ABSTRACT OF THE DISCLOSURE This device for actuating a tip-up or sectional door com- prises an elongated frame structure supporting a linearly mo- vable member driven through a worm screw or a chain connected to the door to be driven, and secured at two upper points of which one is located at one and of the frame structure. This one end is secured to a fixed support formed with a vertical notch of which the bottom edge has a groove formed therein, the upper edge of this notch being limited by a surface lo- cated at a predetermined distance from the groove bottom. The frame structure comprises a bearing surface, for example in the form of a pin, and a locking surface, for example in the form of another pin, located at a distance from the first pin which corresponds to the predetermined distance. This frame structure can be fitted by a single person by anchoring the lower pin of the support and then raising the frame structure to a substantially horizontal position, so as to lock automa- tically the device in its operative position.
