Abstract
Abstract A glazing bead adapted to secure a second, larger thickness of insulated window in a window frame designed to normally receive a first, smaller thickness of insulated window. The glazing bead comprises a plastic extrusion having a resilient, arcuate wall member which engages the window and/or the window frame. Extending outwardly from the wall member is a folded leg member which is inserted between the window and the window frame, thereby compressing it and urging a locking flange on the folded leg member into engagement with the glazing lip on the window frame to secure the glazing bead and the window in place in the window frame. When the glazing bead is snapped into place, the arcuate wall member is compressed and thus resiliently urges said locking flange laterally towards and into engagement with said glazing lip on said window frame. This compression of the resilient wall member also tends to effectuate a seal between it and the window.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
246 words
A glazing bead adapted to secure a second, larger thickness of insulated window means in a window frame means designed to normally receive a first, smaller thickness of insulated or uninsulated window means, wherein the window frame means is of the type having a glazing channel terminating on one side in a glazing lip, wherein the glazing bead comprises: resilient wall means adapted to engage, when installed, the window means and the window frame means; locking means adapted to engage, when installed, the inner edge of the glazing lip on the window frame means; resilient folded leg means, wherein said folded leg means comprises first leg member means which extend outwardly from said wall means and then folds and reverses direction to form second leg member means which extend towards said wall member means, wherein said locking means extends outwardly from said folded leg means; wherein, when said glazing bead is installed, said resilient folded leg means is adapted to be compressed between said window means and said window frame means and urge said locking means towards said frame means into engagement with said glazing lip; and wherein, when said glazing bead is installed, said resilient wall means is adapted to be compressed and resiliently urge said locking means laterally towards and into engagement with said glazing lip; and wherein said compression also tends to bring said resilient wall means into firm contact with at least one of said window means and said window frame means.
Claim 2
Dependent Claim
246 words
A glazing bead adapted to secure a second, larger thickness of insulated window means in a window frame means designed to normally receive a first, smaller thickness of insulated or uninsulated window means, wherein the window frame means is of the type having a glazing channel terminating on one side in a glazing lip, wherein the glazing bead comprises: resilient wall means adapted to engage, when installed, the window means and the window frame means; locking means adapted to engage, when installed, the inner edge of the glazing lip on the window frame means; resilient folded leg means, wherein said folded leg means comprises first leg member means which extend outwardly from said wall means and then folds and reverses direction to form second leg member means which extend towards said wall member means, wherein said locking means extends outwardly from said folded leg means; wherein, when said glazing bead is installed, said resilient folded leg means is adapted to be compressed between said window means and said window frame means and urge said locking means towards said frame means into engagement with said glazing lip; and wherein, when said glazing bead is installed, said resilient wall means is adapted to be compressed and resiliently urge said locking means laterally towards and into engagement with said glazing lip; and wherein said compression also tends to bring said resilient wall means into firm contact with at least one of said window means and said window frame means.
Claim 3
Dependent Claim
19 words
The glazing bead according to claim 1, wherein said resilient wall means has a generally arcuate cross sectional configuration.
Claim 4
Dependent Claim
24 words

Claim 5
Dependent Claim
22 words
The glazing bead according to claim 1, wherein said locking means comprises flange means which extend outwardly from said folded leg means.
Claim 6
Dependent Claim
47 words
The glazing bead according to claim 4, wherein said flange means extend outwardly from said folded leg means for a distance just sufficient to enable said flange means to engage the outermost portion of the inner edge of the glazing lip when said glazing bead is installed.
Claim 7
Dependent Claim
19 words
The glazing bead according to claim 1, wherein said locking means extend outwardly from said first leg member means.
Claim 8
Dependent Claim
17 words
The glazing bead according to claim 1, wherein said glazing bead is a one piece plastic extrusion.
Claim 9
Dependent Claim
31 words
The glazing bead according to claim 1, wherein said glazing bead is adapted to be installed with a snap fit into a previously assembled combination window means and window frame means.
Claim 10
Dependent Claim
55 words
The glazing bead according to claim 1, wherein the window frame means is a mullion means, and the resilient wall means is sized and curved so as to be adapted to avoid interference with a second window means of the type having a Z-Bar vent frame which is movable into contact with the mullion means.
Claim 11
Dependent Claim
31 words
The glazing bead according to claim 1, wherein, when the glazing bead is installed, said resilient wall means are adapted to engage both said window means and said window frame means.
Claim 12
Dependent Claim
48 words
The glazing bead according to claim 1, wherein said glazing bead is adapted to secure an insulated window in said window frame means wherein the thickness of said insulated window is such that the insulated window overlaps the glazing lip on said window frame means when installed therein.
Claim 13
Dependent Claim
49 words
The glazing bead according to claim 1, wherein said glazing bead is adapted to secure an insulated window in said window frame means wherein the thickness of said insulated window is such that the insulated window extends past the glazing lip on said window frame means when installed therein.
Claim 14
Dependent Claim
35 words
The glazing bead according to claim 12, wherein said resilient wall means include foot means which extend outwardly from said resilient wall means and engage said window frame means when said glazing bead is installed.
Claim 15
Dependent Claim
191 words
A glazing bead adapted to secure a window means in a window frame means, wherein the window frame means is of the type having a three sided glazing channel having a floor, a glass supporting member extending upwardly from one side of the floor and a glazing lip extending upwardly from the other side of the floor, wherein said glass supporting member is adapted to support a face of said window means, wherein the edge of said window means is located generally between said glass supporting member and said glazing lip, and wherein the glazing bead comprises: resilient wall means adapted to engage, when installed, at least said window means; locking means adapted to engage, when installed, said glazing lip on the window frame means; and curved, resilient leg means, wherein said leg means extend outwardly from said wall means; wherein said locking means extends outwardly from said leg means; and wherein, when said glazing bead is installed, said leg means is adapted to be compressed between said window means and said window frame means to urge said locking means toward said frame means and into engagement with said glazing lip.
