A WINDOW OPERATOR

摘要

A mechanism for angularly moving a panel or closure element such as a window. The mechanism includes a housing (10) which incorporates a guide (19) in which is slidingly located an elongate multi-link connector (11). One end (17) of the connector (11) is extendable from the housing (10) and is able to be coupled to the panel or closure element by a coupling (12). A handle (13) mounted with the cover (15) of the housing (10) can be rotated to move the connector (11) relative to the guide (19). The connector (11) is formed from a plurality of links (16) maintained in an interengaging relationship by an elongate flexible joining element (30) extending therethrough. The connector includes a plurality of drive dogs (35) for engagement with a toothed gear coupled to the handle (13) so that drive from the handle (13) can be imparted to the connector (11).
