Title
(EN) OPERATING DEVICE FOR A ROTATABLE MEMBER
(FR) DISPOSITIF D'ACTIONNEMENT POUR UN ELEMENT ROTATIF
Abstract
(EN)
An externally mounted lightweight operating device (1) for connection to a rotatable member of a switch or valve e.g. a valve spindle, comprises a drive unit (14) securable to the valve spindle by locking means (18, 20), and a tubular casing (10) which encompasses the drive unit (14). The casing has a part-circumferential slot (30) to provide access for a detachable operating handle (32). The handle (32) is prevented by the slot from being introduced or removed from the drive unit (14) except when the valve is fully closed, whilst to prevent unauthorised use, the drive unit (14) has a profile (42) intended for engagement with a complementary groove (39) formed in the engaging portion of the handle.
(FR)
L'invention concerne un dispositif d'actionnement (1) léger et monté à l'extérieur, prévu pour être relié à un organe rotatif d'un interrupteur ou d'un robinet, par exemple, à une tige de robinet. Ce dispositif comprend un élément d'entraînement (14) pouvant être fixé à la tige du robinet par un moyen de verrouillage (18, 20) et un boîtier tubulaire (10) qui entoure l'élément d'entraînement (14). Ce boîtier présente une encoche partiellement circonférentielle (30) permettant d'introduire une poignée d'actionnement amovible (32). Cette fente empêche la poignée (32) d'être introduite dans l'élément d'entraînement (14), ou retirée de ce dernier, sauf lorsque le robinet est totalement fermé. Par ailleurs, pour éviter toute utilisation non autorisée, l'élément d'entraînement (14) présente un profil (42) prévu pour se mettre en prise avec une rainure complémentaire (39) ménagée dans la partie d'accouplement de la poignée.
