The window structure includes a thermal barrier between a prime window and a storm window. The window is provided with balance foot and lower sash guide structure to permit pivoting of the sash about the lower edge thereof and support of the sash by a sash balance if desired. The balance foot and lower sash guide structure includes a separate balance foot member constructed to be connected to a sash balance in a jamb of the frame and a separate sash guide member pivotally engaged with the balance foot member and secured to a sash stile at the lower end thereof. Pivoting of the window is permitted on release of tilt release and sash guide mechanism at the upper edge of the sash.
Window structure including a generally rectangular outer frame including head jamb and sill members, the jamb members having a longitudinally extending recess therein opening inwardly of the frame, at least one sash positioned within the frame including stiles at the sides thereof having longitudinally extending recesses therein opening outwardly of the sash and a lift rail at the bottom thereof, which sash is movable in the plane of the frame and tiltable about the lift rail out of the plane of the frame, a balance foot member positioned within the longitudinally extending recess in at least one frame jamb movable along the recess with the sash, said balance foot member including a recess therein opening toward said sash and a torque transfer projection extending centrally from said recess in said balance foot member toward said sash in spaced relation to the side walls of said recess in said balance foot member, and a lower sash guide member secured to the sash stile within the recess therein adjacent the lift rail including a cylindrical hollow pivot portion extending therefrom toward the frame jamb receiving the torque transfer projection on the balance foot member extending axially thereinto and itself extending axially into the recess in the balance foot member, said balance foot member and lower sash guide member comprising a balance foot and lower sash guide structure guiding the sash in movement in the plane of the window and providing a pivot for the sash about the lift rail.
Balance foot and sash guide structure for guiding sash in movement in the plane of a window frame and providing a pivot for the sash about one edge of the sash comprising a balance foot member including a recess therein and a torque transfer projection extending centrally from said recess in spaced relation to the side walls of said recess and a sash guide member including a cylindrical hollow pivot portion extending therefrom toward the torque transfer projection on the balance foot member and receiving the torque transfer member extending axially thereinto and itself extending axially into the recess in the balance foot member.
