As the pinions spin, the links of the chain are rotated through the casing at a 90-degree position. This directs the chain into a rigid, straight form, which is extremely resistant to tension and compression. For an electric windowpane opener, the chain offers been mounted on a window. In order the chain is directed into a straight form, the home window is pushed open. And since it retracts into the casing, the windowpane closes.
These are usually fitted to side hung windows or doors, because they provide a 90-degree opening. Also, they are called folding arm actuators and can be designed to open inwards, outwards or both ways.
