Abstract
The window stay comprises a frame mounting plate, a sash mounting plate, a first arm and a second arm. The arms are pivotally coupled between the frame and sash mounting plates via pivots. The first arm is shorter than the second arm. The stay further includes a third arm which is pivotally coupled to the sash mounting plate at a pivot located to the side of pivot coupling which is opposite to pivot coupling of the first arm to the sash mounting plate. This third arm is pivotally coupled to a fourth arm with the fourth arm being pivotally coupled to the frame mounting plate. The first, second and fourth arms include structures which engage with stops associated with the frame and sash mounting plates when the stay is in the fully open position.
