Title
(EN) DRIVE SYSTEM FOR ROTATING A WINDING MEMBER OF A ROLL-UP CLOSING SCREEN APRON
(FR) SYSTÈME D'ENTRAINEMENT EN ROTATION D'UN ORGANE D'ENROULEMENT D'UN TABLIER D'ÉCRAN DE FERMETURE ENROULABLE
Abstract
(EN)
This drive system (1) for rotating a winding member (11) of a roll-up closing screen apron comprises an actuator (3) driving a main shaft (7), a rotating element (9) rotatably secured to the winding member (11), a torsion spring (25), and a disengageable device (2). In the disengaged configuration, the torsion spring (25) is suitable for being preloaded by a relative rotation between the main shaft (7) and the rotating element (9), and the previously preloaded torsion spring (25) drives the rotating element (9) in rotation such that the apron is driven towards a rolled-up configuration. This system also comprises a threaded rod (27) rotatably secured to the main shaft (7) and a slider (29) screwed onto the threaded rod (27) and rotationally fixed relative to the winding member (11) such that the slider (29) is able to move in translation between a first position, in which the spring (25) is not preloaded and the actuator (3) is free to preload the spring (25) by means of free rotation between the main shaft (7) and the rotating element (9), and a second position, in which the spring (25) is preloaded and the slider (29) abuts against an element (31) secured to the main shaft (7) such that the actuator (3) is automatically stopped.
(FR)
Ce système d'entrainement (1) en rotation d'un organe d'enroulement (11) d'un tablier d'écran de fermeture enroulable comprend un actionneur (3) entraînant un arbre principal (7), un élément rotatif (9) solidaire en rotation de l'organe d'enroulement (11), un ressort de torsion (25), et un dispositif débrayable (2). En configuration débrayée, le ressort de torsion (25) est apte à être précontraint par une rotation relative entre l'arbre principal (7) et l'élément rotatif (9), et le ressort de torsion (25) préalablement précontraint entraîne l'élément rotatif (9) en rotation de telle manière que le tablier soit entraîné vers une configuration enroulée. Ce système comprend également une tige filetée (27) solidaire en rotation de l'arbre principal (7) et un curseur (29) vissé sur la tige filetée (27) et fixe en rotation par rapport à l'organe d'enroulement (11) de telle manière que le curseur (29) est mobile en translation entre une première position, dans laquelle le ressort (25) n'est pas précontraint et l'actionneur (3) est libre de précontraindre le ressort (25) par libre rotation entre l'arbre principal (7) et l'élément rotatif (9), et une seconde position, dans laquelle le ressort (25) est précontraint et le curseur (29) est en butée contre un élément (31) solidaire de l'arbre principal (7) de telle manière que l'actionneur (3) est automatiquement stoppé.
