Abstract (en)

A latch (53 min ) on the window frame moves between a locked position, in which it engages a strike on the swingable seal and holds the sash in the closed position, and an unlocked position, in which it releases the strike and frees the sash for movement away from the closed position. A reversible rotary actuator (41 min ) mounted on the frame, is rotated in a first direction to first move the latch (53 min ) from the locked position to the unlocked position and to then move the sash away from the closed position, and it rotated in a second direction to first move the sash the closed position and then to move the latch (53 min ) toward the locked position at about the same time as the sash reaches the closed position. Two nuts (104,105) move along a screw (101) rotated by the actuator (41 min ). A first linkage (115-117) connected between the sash and the first nut (104) is operable to move the sash towards and away from the closed position when first nut (104) is moved in opposite direction along the screw (101). A second linkage (72 min ,77 min ) connected between the latch (53 min ) and the second nut (105) is operable to move the latch (53 min ) toward and away from the locked position when the second nut (105) is moved in opposite directions along the screw (101). When the sash is closed and the latch (53 min ) is locked, movement of the first nut (104) along the screw (101) is delayed until the screw has been rotated sufficiently far to advance the second nut (105) along the screw a predetermined distance. When the sahd is closed and the latch (53 min ) is unlocked, movement of the first nut (104) along the screw (101) in the said closing direction is prevented during rotation of the screw while permitting the second nut (105) to move along the screw in the latch-locking direction.
