Abstract
Abstract A corner formation is made in an architectural glazing strip that has an elastomer-encased spring material formed of a resilient wire element in a transverse pattern of zig-zag loops with the strip having an anchorage edge and a glass-engaging edge. The strip is cut inward from the anchorage edge between the pair of wire loops that occur at the corner, and the cut is stopped at the wire extending between the pair of loops. Then the strip is bent 90° at the corner to open a substantially square space between the wire loops. A resilient element is placed in this space and has the transverse cross-sectional shape of the spring material, and an elastomeric material encases the resilient element and is secured to the strip around the corner. The result provides an even and uniform corner having resilient pressure all the way around the corner.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
162 words
A corner formation for an architectural glazing strip having a spring material formed of a resilient wire element in a transverse pattern of zig-zag loops encased in an elastomeric cover to have an anchorage edge region and a glass-engaging edge region, said wire loops extending from said anchorage edge region into said glass engaging edge region, said corner formation comprising: a. the pair of said wire loops occurring at said corner and said elastomeric cover over said pair of loops being spread apart about 90° to open a substantially square space at said corner with an unbroken length of said wire extending around the inside of said corner between said pair of loops in the region of said glass-engagind edge; b. a substantially square, resilient element having approximately the transverse cross-sectional shape of said spring material being positioned in said square space between said spread-apart loops; and c. elastomeric material encasing said resilient element and secured to said strip around said corner.
Claim 2
Dependent Claim
162 words
A corner formation for an architectural glazing strip having a spring material formed of a resilient wire element in a transverse pattern of zig-zag loops encased in an elastomeric cover to have an anchorage edge region and a glass-engaging edge region, said wire loops extending from said anchorage edge region into said glass engaging edge region, said corner formation comprising: a. the pair of said wire loops occurring at said corner and said elastomeric cover over said pair of loops being spread apart about 90° to open a substantially square space at said corner with an unbroken length of said wire extending around the inside of said corner between said pair of loops in the region of said glass-engagind edge; b. a substantially square, resilient element having approximately the transverse cross-sectional shape of said spring material being positioned in said square space between said spread-apart loops; and c. elastomeric material encasing said resilient element and secured to said strip around said corner.

Claim 6
Independent Claim
176 words
A method of forming a corner for an architectural glazing strip having a spring material formed of a resilient wire element in a transverse pattern of zig-zag loops encased in an elastomeric cover to have an anchorage edge and a glass-engaging edge, said corner forming method comprising: a. cutting said strip at said corner between a pair of said loops so said cut extends from said anchorage edge of said strip toward said glass-engaging edge of said strip; b. stopping said cut at the wire extending between said pair of loops in the region of said glass-engaging edge so said wire extends around the inside of said corner between said pair of loops; c. bending said strip at said cut by approximately 90° to open up a substantially square space at said corner; d. placing a substantially square resilient element having approximately the transverse cross-sectional shape of said spring material in said corner space formed by bending said strip; and e. encasing said resilient element in an elastomeric cover secured to said strip around said corner.
