Abstract
Abstract A channel-shaped retainer strip is secured to the edge of a window glass to retain the glass in a plastic frame and form a seal between the glass and the frame. The bodies of the frame and the retainer strip are formed of relatively strong and hard plastic, and the retainer strip has relatively soft plastic seal fins engaging the outside of the glass and the frame to seal the glass in the frame. Confronting surfaces between the frame and the retainer strip are formed with interlocking projections of soft plastic material that allow the glass to be pressed into the frame and resist movement of the glass back out of the frame to retain the glass in place.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
249 words
A window glass glazing system comprising: a. a support construction built in place around an opening for said window glass; b. a frame liner surrounding said glass and having a surface facing inward around said glass; c. means for attaching said frame liner to said construction; d. said frame liner being shaped to form a surface covering applied over said construction; e. a channel-shaped retainer strip secured astraddle the edge of said glass to hold said glass in said frame liner and form a seal between said glass and said frame liner; f. the bodies of said frame liner and said retainer strip being formed of relatively strong and hard plastic material; g. said retainer strip having a glass seal fin formed of relatively soft and resilient plastic material and oriented to press against the out-side of said glass; h. the outside edge of said retainer strip having a frame seal fin formed of relatively soft and resilient plastic material and oriented to press against said frame liner; i. said retainer strip having a surface confronting said inward facing surface of said frame liner; j. said confronting surfaces of said retainer strip and said frame liner being configured to allow said glass to be pressed into said frame liner from one side thereof; k. said confronting surfaces having projections oriented to interlock to resist movement of said glass toward said one side of said frame liner; and l. said projections being formed of relatively soft and resiliently plastic material
