A door or window stay is connectable between a closure and a frame to allow the closure to be opened out of and closed into the frame. The stay has an arm (11) connected to a base member (10) by a linkage (12, 13, 14, 60) which controls movement of the arm (11) between closed and open positions. The linkage includes a shorter link (12) pivotally connected to one end of the arm (11) and to the base member (10) and a longer link (14) pivotally connected to the arm (11) intermediate the ends of the arm and pivotally connected to a slide (17) carried by the base member (10). The slide (17) has a spring strip (25; 30) which projects from the end of the base member (10) and engages the base member (10) or a lug (34) on the base member when the arm (11) is partially open. The spring strip (25; 30) can be moved to disengage from the base member (10) or the lug (34) to allow continued opening movement of the arm (11). The shorter link (12) may be connected to a second slider (50) carried by the base member. A catch (51) may be carried on this second slider (50) and be movable to a position in which the catch (51) limits movement of the second slider (50) relative to the base member so limiting movement of the arm (11) away from the overlying position. The catch may be rotatable member with an ear (55) engaging in a slot (57) in the base member (10) - such a catch (51) may be used separately from the spring strip (25; 30). |
