Abstract:
1. A window assembly comprising a frame and a sash, the frame being elongated relative to the sash and the sash being slidable 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 balance 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 sash tilt limit bar, said bar having a first end 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 sash when tilted open causing the second end of the bar to travel 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 within the channel, the bar limiting the tilted open positions of the sash to positions which do not cause the second end of the bar to travel sufficiently far along the channel to place the bar in a position extending perpendicular to the frame of the window assembly.
