Abstract
Abstract A panel-holding strip or sash of extruded plastic composition which includes a pair of opposed channel-forming webs connected by an integral longitudinally coextensive, flexible bight or hinge web; the channel-forming webs being relatively movable in the manner of a book cover between a first open position in which the webs are disposed in angular relation to admit the edge portion of a panel or pane therebetween and a second, closed position in which the webs are frictionally interlocked in channel-forming configuration to hold the edge portion of a panel or pane therebetween; each of the channel-forming webs being formed on their opposing inner surfaces with a first set of relatively engageable and interlocking ribs to frictionally and releasably hold the webs in their closed, channel-defining position and a second set of relatively flexible ribs arranged to frictionally grip and seal the edge portion of a panel or pane positioned between the channel-forming webs of the strip or sash.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
178 words
A panel-holding strip comprising an elongated, one-piece body of dual durometer, extruded plastic composition, said body including a pair of opposed, longitudinally coextensive, generally flat rectangular, rigid, channel-forming webs connected along adjacent longitudinal edges thereof by an intergral, flexible hinge web, said channel-forming webs being movable between an angularly related open position and a closed, channel-defining position in which said channel-forming webs are disposed in relatively closely spaced apart parallel relation, and each of said channel-forming webs having an inner surface which includes sets of longitudinally coextensive, transversely spaced apart, parallel, inwardly projecting ribs, one set of the ribs on one of said channel-forming webs being arranged to frictionally interlock with a set of ribs on the other of said channel-forming webs to releaseably hold said channel-forming webs in their closed, channel-defining position, and other sets of the ribs on each of said channel-forming webs being flexible and being arranged in spaced opposition to one another to frictionally grip and seal the edge of a panel inserted between said channel-forming webs when they occupy their closed, channel-defining position.
Claim 2
Dependent Claim
178 words
A panel-holding strip comprising an elongated, one-piece body of dual durometer, extruded plastic composition, said body including a pair of opposed, longitudinally coextensive, generally flat rectangular, rigid, channel-forming webs connected along adjacent longitudinal edges thereof by an intergral, flexible hinge web, said channel-forming webs being movable between an angularly related open position and a closed, channel-defining position in which said channel-forming webs are disposed in relatively closely spaced apart parallel relation, and each of said channel-forming webs having an inner surface which includes sets of longitudinally coextensive, transversely spaced apart, parallel, inwardly projecting ribs, one set of the ribs on one of said channel-forming webs being arranged to frictionally interlock with a set of ribs on the other of said channel-forming webs to releaseably hold said channel-forming webs in their closed, channel-defining position, and other sets of the ribs on each of said channel-forming webs being flexible and being arranged in spaced opposition to one another to frictionally grip and seal the edge of a panel inserted between said channel-forming webs when they occupy their closed, channel-defining position.
Claim 3
Dependent Claim
37 words
A panel-holding strip according to claim 1 which further includes an adhesive strip carried on the outer surface of one of the channel-forming webs of said body for adhesively securing said panel-holding strip to a supporting surface.
Claim 4
Dependent Claim
35 words
A panel-holding strip according to claim 1, wherein the frictionally interlocking ribs of one of said channel-forming webs are spaced transversely farther apart than the complemental interlocking ribs of the other of said channel-forming webs.
Claim 5
Dependent Claim
28 words
A panel-holding strip according to claim 1, in combination with a transparent plastic sheet having an edge portion thereof held between the flexible ribs of said channel-forming webs.
Claim 6
Dependent Claim
22 words
A panel-holding strip according to claim 3, wherein the frictionally interlocking ribs of each of said channel-forming webs terminate in hook-shaped beads.
