Abstract:
A window assembly comprising a frame and a sash, the frame being elongated relative to the sash and the sash being slideable to different vertical settings in the frame, said frame having side jambs with interior channels opening at the sash, each of said channels being provided with a balancing device which slides with and balances weight of said sash at the different vertical settings of the sash in the frame, said sash also being tiltable between a tilted closed position and different tilted open positions relative to the frame, said assembly further including a moveable sash tilt limit bar and a bar movement controller, said bar having a first end pivotally attached to said sash and a second end which is slideably held within one of the channels of the frame, said frame, said sash, and said bar all being vertically aligned with one another and said bar being sandwiched between said frame and said sash when the sash is in the tilted closed position, the first end of the bar being secured by a pivoting mounting to the sash and pivoting at the sash as the sash is tilted open causing the second end of the bar to slide vertically relative to the one of the channels of the frame within which the second end of the bar is slideably held without interfering with the balance device therein resulting in a horizontal tipping of the bar as the sash is tilted open, said bar movement controller limiting the pivoting at the first end of the bar to stop vertical travel of the second end of the bar before the bar tips to a position perpendicular to the frame when the sash is tilted open.
