Abstract
Abstract Universal window structure which may be used as a single hung window, as a hopper window and as a right or left hand glider window without alteration is disclosed. Mulling means for securing a plurality of the window structures together, retaining clips for securing a screen thereto, false muntin structure, hurricane clips and piggyback storm window structure therefor and window trim structure for use therewith are specifically disclosed along with unique glazing strips, an insert for supporting sash balance structure, sealing strips and corner inserts, sash pivot structure, lock structure, sash guide and tilt release structure and hopper lock means for retaining the window sash in a plurality of separate tilted hopper positions. The frame of the window structure is constructed to permit rapid, accurate assembly with a minimum of low tolerance parts and to this end includes frame jamb adaptor extrusions. In addition, the total frame design allows many design variations whereby the universal window structure may be applied to and fit different building needs without additional job working or processing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
139 words
A glazing strip for securing a glazing panel in a window structure or the like, comprising an elongated resilient member having a cross section including a first substantially straight portion, one end of which is independently flexible, the other end of which is adapted to engage a recess in the window frame for securing the glazing strip in the window frame, a second substantially straight portion depending substantially perpendicularly from the one end of the first portion adapted to engage a glazing panel positioned in the window frame for securing the glazing panel in the window frame, and a third substantially straight portion one end of which is connected to the first portion which diverges from the first portion toward the other end of the first portion for securing the glazing strip in the recess in the window frame.
Claim 2
Dependent Claim
139 words
A glazing strip for securing a glazing panel in a window structure or the like, comprising an elongated resilient member having a cross section including a first substantially straight portion, one end of which is independently flexible, the other end of which is adapted to engage a recess in the window frame for securing the glazing strip in the window frame, a second substantially straight portion depending substantially perpendicularly from the one end of the first portion adapted to engage a glazing panel positioned in the window frame for securing the glazing panel in the window frame, and a third substantially straight portion one end of which is connected to the first portion which diverges from the first portion toward the other end of the first portion for securing the glazing strip in the recess in the window frame.
Claim 3
Dependent Claim
35 words
Structure as set forth in claim 1 wherein the other end of the first portion and the third portion of the cross section of the glazing strip form an angle of less than 180° therebetween.
Claim 4
Dependent Claim
175 words
A glazing strip for securing a glazing panel in a window structure or the like, comprising an elongated resilient member having a cross section having a first substantially straight portion, one end of which is independently flexible, the other end of which is adapted to engage a recess in the window frame for securing the glazing strip in the window frame, a second substantially straight portion depending substantially perpendicularly from the one end of the first portion adapted to engage a glazing panel positioned in the window frame for securing the glazing panel in the window frame, a third substantially straight portion one end of which is connected to the first portion which diverges from the first portion toward the other end of the first portion for securing the glazing strip in the recess in the window frame, and a fourth straight portion extending substantially perpendicularly from said other end of said first portion in the direction of said second portion for aiding in securing the glazing strip in the recess in the window frame.
Claim 5
Dependent Claim
175 words
A glazing strip for securing a glazing panel in a window structure or the like, comprising an elongated resilient member having a cross section having a first substantially straight portion, one end of which is independently flexible, the other end of which is adapted to engage a recess in the window frame for securing the glazing strip in the window frame, a second substantially straight portion depending substantially perpendicularly from the one end of the first portion adapted to engage a glazing panel positioned in the window frame for securing the glazing panel in the window frame, a third substantially straight portion one end of which is connected to the first portion which diverges from the first portion toward the other end of the first portion for securing the glazing strip in the recess in the window frame, and a fourth straight portion extending substantially perpendicularly from said other end of said first portion in the direction of said second portion for aiding in securing the glazing strip in the recess in the window frame.
Claim 6
Dependent Claim
66 words
Structure as set forth in claim 3 and further including a fifth portion connected to the first portion adjacent the other end thereof and extending substantially perpendicularly thereto in the direction of the second and fourth portions for engagement with the window pane to flex the first portion to facilitate positioning of the fourth portion of the glazing strip cross section in the window frame recess.
