An operator for hinged windows and being of the kind including a chain which can flex in one direction only and which provides the support whereby the window is held open. Movement of the chain into and out of the operator housing is controlled by a sliding actuator which is moveable along an elongate guide track between two extreme positions corresponding to the window closed and fully opened positions respectively. The actuator can be retained in any selected position between the two extremes by engagement between a spring loaded detent and a toothed rack. The detent is carried by the actuator and the rack is fixed relative to the guide track. Release of the detent is effected by moving a lever connected to the detent against a fixed handle of the actuator and the actuator can be moved along the guide track while the lever and handle are so engaged. When the actuator is in the window closed position, the detent can be moved into a camming and locking recess by separation of the lever and handle and engagement of the detent with that recess causes an associated window to be drawn firmly into the closed position and also positively locks the actuator in the window closed position.
A window operator including an elongate guide track and a flange projecting outwardly from said guide track and extending along substantially the entire length of the guide track, said flange having a slot which extends substantially parallel to said guide track, a manually operable actuator mounted on said guide track and extending beyond said flange for sliding movement therealong between two extreme positions corresponding to window closed and fully open positions respectively, a length of chain having an inner end connected to said actuator for movement therewith and an outer end attachable to a window to be controlled by said operator, guide means co-operating with said chain to cause a stored portion of said chain to generally follow the path of said guide track, said stored position including and extending from said chain inner end, an active portion of said chain extending between said guide means and said chain outer end and the relative proportions of said stored and active portions varying according to the position of said actuator along said track said chain stored portion and said actuator being located on opposite sides of said flange and being interconnected by connecting means extending through said slot, and retaining means operable to releasably hold said actuator at any one of a plurality of selected positions between said two extreme positions.
A window operator including, a guide track comprising an elongate member, a channel formed through a face of said member and extending longitudinally thereof, a lip extending along one side of the open mouth of said channel to provide a restricted opening for that channel, an actuator mounted on said guide track for sliding movement therealong between two extreme positions corresponding to window closed and fully open positions respectively, said actuator including a slide member having a body which is located externally of said channel and which has a side thereof arranged for enagement with said face of the elongate member, a rib connected to said slide member body and being slideably located within said channel, a web section forming the connection between said rib and said slide member body and extending through said narrow opening of said guide track member, a length of chain having an inner end connected to said actuator for movement therewith and an outer end attachable to a window to be controlled by said operator, and retaining means operable to releasably hold said actuator at any one of a plurality of selected positions between said two extreme positions.
A window operator including, an elongate guide track, an actuator mounted on said guide track for sliding movement therealong between two extreme positions corresponding to window closed and fully open positions respectively, a length of chain having an inner end connected to said actuator for movement therewith and an outer end attachable to a window to be controlled by said operator, a toothed rack extending substantially parallel to said guide track and being fixed relative thereto, a detent attached to said actuator for movement therewith and being co-operable with said rack to retain said actuator in a selected one of a plurality of positions between said two extreme positions, and release means attached to said detent to permit selective disengagement of said detent from said rack.
