Abstract
A mechanism for angularly moving a closure element to and from open and closed positions. The mechanism includes a housing which incorporates a guide in which is slidingly located an elongate multi-link connector. One end of the connector is extendible from the housing and is able to be coupled to the closure element by a coupling. A handle mounted with the cover of the housing can be rotated to move the connector relative to the guide. The connector is formed from a plurality of links maintained in an interfitting relationship by an elongate flexible joining element extending therethrough. The connection includes a plurality of drive dogs for engagement with the tooth gear coupled to the handle so that drive from the handle can be imparted to the connector.
