Abstract
A glazing device is formed of a longitudinal strip engaging and holding the periphery of a glass panel, and the strip is formed of a length of spring material with an extruded elastomeric covering. The spring material is formed of a high-tensile-strength, resilient wire element formed in a transverse pattern of zig-zag loops with longitudinally extending rows of knitted strands linking the loops together. The strip is anchored in place against the glass panel so the spring material extends from the anchorage into a cantilevered portion of the strip to engage the glass panel in a displaced position flexing the spring material to produce a predetermined pressure against the glass.
Claims4
A glazing device for supporting a glass panel in place relative to an anchorage region around said glass panel, said glazing device including longitudinally extending inner and outer strips interlocked together and supported in place in said anchorage region to have a cantilevered free end portion of each of said strips extending farthest from said anchorage region and respectively engaging inner and outer peripheral surfaces of said glass panel, each of said strips comprising a length of spring material and an elastomeric material extruded over and encasing said spring material, and said glazing device comprising:
- a. said spring material being in a fixed position in said anchorage region and extending to said cantilevered free end portion of each of said strips to a relatively movable position in the region of said engagement of each of said strips with said glass panel;
- b. said spring material extending closely around the region of said interlock between said strips to provide gripping force for said interlock for firmly holding said strips in interlocked relation so said spring material in said cantilevered free end portion of each of said strips is flexibly displaced from a relatively relaxed position to a position forcing said engagement region of each of said strips against said glass panel with a predetermined pressure sealing and holding said glass panel in place;
- c. said spring material being formed of a resilient wire element formed in a transverse pattern of zig-zag loops, said pattern extending along the length of each of said strips;
- d. longitudinally extending rows of knitted strands linking said loops together in said zig-zag pattern;
- and
- e. said predetermined pressure being a function of the tensile strength of said wire element, the diameter of said wire element, the material of said wire element, and the number of said loops per unit of length of said strip.
