A window stay

摘要

A window stay for the adjustable mounting of a window sash in a window frame. The stay comprises a frame mounting plate (10) and a sash mounting plate (11) which are coupled by a short arm (12) and a long arm (13) joined to the mounting plates via pivot joints (14). The open position of the stay is defined by a stop (30) which engages with edge (31) of short arm (12). The stop (30) exhibits a degree of flexibility as it is contacted by the arm (12) to thereby provide an energy absorbing function. A roller (22) is mounted with a pad (17) and engages with the short arm (12) as arm (12) moves to a fully closed position defined by at least edge (19) contacting an upstand (18) of the pad (17).
