WEATHERTIGHT SLIDING SASH WINDOW ASSEMBLY

摘要

A weathertight sash window assembly including a pair of first and second engaging members disposed on and extending longitudinally of a pair of meeting first stile and second stile, respectively. The first engaging member is movable between a first position in which the first engaging member pulls or draws the second engaging member toward the interior of the window assembly to force the second stile into a firm engagement with the first stile throughout their length, and a second position in which the first engaging member releases the second engaging member to allow disengagement of the sashes from each other. The sash window assembly further includes means on the first stile for moving the first engaging member between the first and second positions in response to movement of a first fastener member between its locked and unlocked positions. The advance in the art is in that a uniform engagement between the sashes is achieved to improve the sealing effect of the window assembly.
