Universal window structure for use as a single-hung window, a hopper window, or a right or left-hand glider window and having a box frame and at least one movable sash is disclosed. An improved mull cover for securing a plurality of the universal window structures together, sash guide and tilt release structure for permitting tilting of the movable sash out of the plane of the window structure, and sash guide and pivot structure for the movable sash are also disclosed, together with an improved sash balance shoe, improved locking structure for the movable sash, improved glazing structure, improved weather stripping, structure for maintaining the weathertightness of the window structure during high winds, and a combination screen retainer and movable sash seal. The window structure of the invention may be installed from the inside of a window opening by means of unique installation clips and can be installed from the exterior of a window opening in conjunction with a unique installation bracket. Trim extensions are also provided with the window structure for finishing a window opening in which the window structure is installed. The window structure of the invention has provision for weepage installed as a single-hung hopper or as a right or left-hand glider window. The movable sash of the window structure of the invention is separated from the frame thereof and guiding and spacing means to eliminate metal-to-metal engagement between the movable sash and the window frame are provided whereby the window structure is particularly quiet in operation.
Window structure for installation both as a single-hung window or as a hopper window and as a right or left hand glider window including a frame having a fixed frame rail, guiding frame rails, a locking frame rail and a frame check rail, at least one movable sash secured within the frame for selective movement in the plane of the window frame and tilting out of the plane of the window frame about one edge of the sash including a tilt rail, guide rails having longitudinal recesses therein and a lock rail, and sash guide and pivot structure positioned at least partly within the longitudinal recesses of the sash guide rails and secured to opposite corners of the movable sash, spacing the movable sash from the frame rails, finishing the ends of the movable sash guide rails at the ends of the sash lock rail to prevent damage to weather stripping on pivoting of the movable sash about the lock rail thereof and providing a pivot axis for the movable sash on pivoting thereof, which sash guide and pivot structure is operable to lock the movable sash in pivoted povition with respect to movement of the movable sash along the frame, which ash guide and pivot structure includes a rectangular portion adapted to fit within the movable sash guide rail at the end thereof adjacent an end of the sash lock rail, an L-shaped flange extending over perpendicular sides of the rectangular portion for engaging the side and one end of the guide rail of the movable sash and an elongated pivot portion extending on the opposite side of the flange from the rectangular portion of the sash guide and pivot structure and away from the sash guide rail and into the guiding frame rail in installation on a movable sash installed in the window structure and having a larger dimension in the plane of the window structure than transversely of the window structure whereby on tilting of the movable window sash the pivot portion of the sash guide and pivot member extending within the guiding frame rail engages portions of the rail to lock the movable sash in the fram with respect to movement of the sash along the frame.
Structure as set forth in claim 28, wherein the sash balance shoe further includes an arcuate side portion for permitting rotation of the sash balance shoe into the pocket in installation.
Sash guide and pivot structure comprising a rectangular portion adapted to fit within a window sash guide rail at the one end of the lock rail thereof, an L-shaped flange on perpendicular sides of the rectangular portion for engaging the side and end of the sash guide rail and an elongated noncircular pivot portion extending on the opposite side of the flange from the rectangular portion of the sash guide and pivot member.
Sash guide and pivot structure comprising a rectangular portion adapted to fit within a window sash guide rail at the one end of the lock rail thereof, an L-shaped flange on perpendicular side of the rectangular portion for engaging the side and end of the sash guide rail, an elongated non-circular pivot portion extending on the opposite side of the flange from the rectangular portion of the sash guide and pivot member and a flexible extension secured to the flange portion of the sash guide and pivot structure and extending away from the rectangular and pivot portions of the sash guide and pivot structure including a balance shoe retaining barb on the outer end thereof projecting in the same direction as the pivot portion of the sash guide and pivot member.
A sash balance shoe including vertically extending recesses on two sides thereof and a centrally located slot extending therebetween constructed to receive the offset end of a sash balance torsion ribbon.
A sash balance shoe including vertically extending recesses on two sides thereof and a centrally located slot extending therebetween constructed to receive the offset end of a sash balance torsion ribbon, which sash balance shoe further includes a surface on one side thereof for engagement with an inside surface of a guiding frame rail on one side of a pocket therein and a surface on the other side thereof for engagement with an outside surface of a guiding frame rail on the other side of the pocket therein with the sash balance torsion ribbon being stressed to rotate the sash balance shoe toward the other side of the pocket on the outside of the pocket.
Window structure for installation both as a single-hung window or as a hopper window and as a right or left-hand glider window including a frame having a fixed frame rail, guiding frame rails, a locking frame rail and a frame check rail, at least one movable sash secured within the frame for selective movement in the plane of the window frame and tilting out of the plane of the window frame about one edge of the sash including a tilt rail, guide rails having longitudinal recesses therein and a lock rail, and sash guide and pivot structure positioned at least partly within the longitudinal recesses of the sash guide rails and secured to opposite corners of the movable sash, spacing the movable sash from the guiding frame rails, finishing the ends of the movable sash guide rails at the ends of the sash lock rail to prevent damage to weather stripping on pivoting of the movable sash about the lock rail thereof and providing a pivot axis for the movable sash on pivoting thereof, which sash guide and pivot structure is operable to lock the movable sash in a pivoted position with respect to movement of the movable sash along the frame.
Window structure including a frame having a fixed frame rail, guiding frame rails, a locking frame rail and a frame check rail, at least one movable sash secured within the frame for selective movement in the plane of the window frame and tilting out of the plane of the window frame about one edge of the sash including a tilt rail, guide rails having longitudinal recesses therein and a lock rail, sash guide and pivot structure positioned at least partly within the longitudinal recesses of the sash guide rails and secured to opposite corners of the movable sash, spacing the movable sash from the guiding frame rails, finishing the ends of the movable sash guide rails at the ends of each lock rail to prevent damage to weather stripping on pivoting of the movable sash about the lock rail thereof and providing a pivot axis for the movable sash on pivoting thereof, which sash guide and pivot structure is operable to lock the movable sash in a pivoted position with respect to movement of the movable sash along the frame, and a sash balance shoe positioned within at least one of the guiding frame rails and engaged with a portion of the sash guide and pivot structure whereby the sash balance shoe is releasably secured in position against the bias of a sash balance secured thereto.
Sash guide and pivot structure comprising a rectangular portion adapted to fit within a window sash guide rail and a substantially flat flexible extension secured to the rectangular portion adapted to extend substantially flat against a window sash guide rail including a balance shoe retaining barb on the outer end thereof extending away from the rectangular portion thereof.
