They work via a motorised folding arm that’s attached to a window. The arm begins in a folded placement, however as it is powered by the engine, it begins to unfold. The arm is positioned in a way that as it starts to unfold, the window begins to open up. To close a home window, the arm begins to fold back up into its unique position, bringing the windows to a close.
Chain actuators work similarly to rack and pinion actuators. A chain engages with pinions which have been installed on a drive shaft in a external casing. As the pinions spin, the links of the chain are rotated through the casing at a 90-degree position. This directs the chain right into a rigid, straight form, which is extremely resistant to tension and compression. For an electric window opener, the chain has been attached to a window. In order the chain is directed into a straight form, the windowpane is pushed open. And since it retracts into the casing, the windowpane closes.
These are usually suited to side hung windows or doors, as they offer a 90-degree opening. Also, they are known as folding arm actuators and will be designed to open up inwards, outwards or both methods.
