Window stays

摘要

A window stay of a geometry whereby, in the closed position of the stay, the pivot coupling the long arm to the sash plate is situated between the pivots respectively coupling the frame and sash plates to the short arm. The short arm is provided with a fold located between the pivot points thereof and extends substantially diagonally relative to an imaginary line between the pivot points. The pivot coupling the short arm to the frame plate is offset to the other pivots when the stay is closed by the frame plate forms an angle with respect to the length of the frame member to which the frame plate is, in use, attached.
