Abstract:
La présente invention se rapporte à un dispositif (1) de fermeture automatique d'un ouvrant coulissant, notamment une porte (2) de placard, comprenant au moins un boitier (4) fixé en bas ou en haut de la porte (2), et un axe sur lequel est montée une roue (3) coopérant avec un rail de guidage (5) de la porte (2), laquelle roue (3) est intégrée au boitier (4) et est assujettie à un ressort spiral (6) de manière que lors d'une rotation de celle-ci dans un sens d'ouverture de la porte (2) s'effectuant manuellement, le ressort (6) s'enroule et emmagasine de l'énergie, qu'il restitue à la roue (3) qui devient motrice, pour un retour en fermeture automatique de la porte (2), caractérisé en ce qu'il comporte des moyens de blocage-déblocage (15,23) de la roue (3), d'où de la porte (2), dans n'importe quelle position de celle-ci.
Abstract:
The device has a jack to stress a hatch in the direction of its opening. A retractor cable (18) mounted on a plate (24) is wound on a winding drum (22). An engine (26) drives the drum in rotation around its axis. A ring gear (38), ball and piston (42) engage and release the drum with respect to an output shaft (26A). The shaft and rotation axis of the drum are aligned along a common axis (AC).
Abstract:
A drive assembly moves a vehicle closure panel from an open to a closed condition. The drive assembly has a housing and a motor mounted on the housing. A drum and gear assembly is rotatably mounted on the housing. The drum and gear assembly has a drum having a helical groove, a gear in driving engagement with the motor, and a spring biasing the drum in a winding direction relative to the gear. The drum and gear have a lost motion connection therebetween. A cable has an end connected to the closure panel and an opposite end connected to the drum about the helical groove in the winding direction. The drum rotates in the winding direction relative to the stationary gear as the closure panel is manually moved from the open to the closed condition with the spring maintaining a cable tension. The drum and gear rotate together in the winding direction upon energizing the motor effecting powered movement of the closure panel to the closed condition. The motor is afterwards energized in an opposite direction counter-rotating the gear relative to the drum back to a start position.
