CA 2525226

A device (1) for winding or unwinding of a shade (11, 12, 33, 34) comprises a single drive motor (3) having a drive shaft over which transmission devices can be slit. Each transmission device can operate a substantially horizontal tube (9, 10) which is movable with winding or unwinding of the shade (11, 12) upwardly or downwardly. The transmission devices (7, 8) have a slip coupling which can be blocked electrically and mechanically. In the blocked condition of the transmission device (7, 8) the tube is stationary whilst the drive shaft (4) can keep rotating for operating of further non-blocked tubes. The tubes (7, 8) can be stopped in any desired position for more or less winding or unwinding the related shade (11, 12) whilst only a single drive motor (3) is necessary.

L'invention concerne un dispositif (1) d'enroulement ou déroulement d'un store (11, 12, 33, 34) comprenant un moteur à commande simple (3) ayant un premier axe de commande, au-dessus duquel des dispositifs de transmission peuvent être placés. Chaque dispositif de transmission peut mettre en marche un tube sensiblement horizontal (9, 10) qui se déplace avec l'enroulement ou le déroulement du store (11, 12) de haut en bas ou de bas en haut. Les dispositifs de transmission (7, 8) présentent un couplage coulissant qui peut être bloqué électriquement et mécaniquement. A l'état bloqué du dispositif de transmission (7, 8), le tube est stationnaire alors que l'axe de commande (4) peut continuer à tourner en vue du fonctionnement d'autres tubes non bloqués. Les tubes (7, 8) peuvent être arrêtés dans une quelconque position souhaitée selon un enroulement ou déroulement souhaité du store (11, 12) alors que seul un moteur à commande simple (3) est nécessaire.
