Abstract
A window stay for adjustable mounting of a window sash into a window frame which comprises a first mounting plate adapted for attachment to the frame of a window and a second mounting plate adapted for attachment to the sash of a window. A carriage is slidably mounted on the first mounting plate. An arm is pivotally connected by one end to the sash mounting plate and by the other end to the frame mounting plate. The sash mounting plate is further pivoted but at a point remote from the pivot coupling the arm to the frame mounting plate to the slidably mounted carriage. Means are provided which cause the carriage to be angularly displaced relative to the frame mounting plate during the initial opening and closing.
