ABSTRACT:
A locking mechanism for a sash type window comprising two adjacent sashes arranged to slide one behind the other in a generally horizontal direction within an enclosing frame is disclosed. When the window is in its closed position, actuation of the locking mechanism causes the sashes to slide relative to one another in a direction away from each other to assure better sealing between the sashes and the enclosing window frame. In a preferred embodiment, the two sashes are also drawn towards each other in a direction perpendicular to the sliding direction in order to obtain better sealing between the sashes themselves. The locking mechanism may also be used on sliding doors.
