Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
131 words
A generally channel-shaped strip structure for clamping retention on an edge flange, said strip structure comprising: a reinforcement core member having in cross-section, a channel shape defined by a first and a second leg of said core member joined by a web; said first leg being joined to a reentrant free end of said core member extending inwardly into said channel by a radius portion of said core member having reduced thickness relative to said free end and said first leg adjacent thereto; and an elastomeric cover layer bonded to said reinforcement core member, said elastomeric cover layer including means for retaining the strip structure onto an associated edge flange, said retaining means positioned on said member extending inwardly from at least one of said legs of said reinforcement core member.
Claim 2
Dependent Claim
131 words
A generally channel-shaped strip structure for clamping retention on an edge flange, said strip structure comprising: a reinforcement core member having in cross-section, a channel shape defined by a first and a second leg of said core member joined by a web; said first leg being joined to a reentrant free end of said core member extending inwardly into said channel by a radius portion of said core member having reduced thickness relative to said free end and said first leg adjacent thereto; and an elastomeric cover layer bonded to said reinforcement core member, said elastomeric cover layer including means for retaining the strip structure onto an associated edge flange, said retaining means positioned on said member extending inwardly from at least one of said legs of said reinforcement core member.
Claim 3
Dependent Claim
49 words
A strip structure as in claim 1 wherein said first leg, web and second leg provide a first spring portion and said reentrant free end, radius portion and first leg provide a second spring portion, said first spring portion requiring larger force for deflection than said second spring portion.
Claim 4
Dependent Claim
27 words
A strip structure as in claim 2 wherein said retaining means of said elastomeric cover comprises at least one rolling lock member and at least one rib.
Claim 5
Dependent Claim
20 words
A strip structure as in claim 3 wherein said ribs are in opposite to spaces between said rolling lock members.
Claim 6
Dependent Claim
16 words
A strip structure as in claim 2 wherein said second leg has a circular tail portion.
Claim 7
Dependent Claim
34 words
A strip structure as in claim 5 wherein said second leg has a shoulder portion intermediate said web and said circular tail portion, said shoulder portion being adapted to engage an associated flange shoulder.
Claim 8
Dependent Claim
42 words
A strip structure as in claim 6 wherein said elastomeric cover has, in cross-section, a finger proximate to said radius and extending toward said second leg, said finger providing means for guiding a flange between said rolling lock member and said rib.
Claim 9
Dependent Claim
103 words
A weatherstripping comprising: a reinforcement core member having, in cross-section an overall channel shape; a leg on said channel-shaped reinforcement core member including a first and second spring portion, said second spring portion requiring a deflection force less than a deflection force required to deflect the first spring portion, wherein said second spring portion comprises a reduction in thickness of said reinforcement core member; and an elastomeric cover layer bonded to said reinforcement core member, said elastomeric cover layer including means for retaining the weatherstrip structure onto an edge flange, said retaining means being coupled with said reinforcement core member second spring portion.
Claim 10
Dependent Claim
103 words
A weatherstripping comprising: a reinforcement core member having, in cross-section an overall channel shape; a leg on said channel-shaped reinforcement core member including a first and second spring portion, said second spring portion requiring a deflection force less than a deflection force required to deflect the first spring portion, wherein said second spring portion comprises a reduction in thickness of said reinforcement core member; and an elastomeric cover layer bonded to said reinforcement core member, said elastomeric cover layer including means for retaining the weatherstrip structure onto an edge flange, said retaining means being coupled with said reinforcement core member second spring portion.
Claim 11
Dependent Claim
22 words
A weatherstripping as in claim 8 wherein said retaining means comprises at least one rolling lock member and at least one rib.
Claim 12
Dependent Claim
34 words
A weatherstripping as in claim 9 wherein said reinforcement core member has a second leg having a shoulder portion adapted to engage an associated shoulder on a flange when said weatherstripping is mounted thereon.
Claim 13
Dependent Claim
45 words
A weatherstripping as in claim 10 wherein said elastomeric cover layer has in cross-section, a finger extending inwardly into said channel proximate to said second spring portion requiring less deflection force and adapted to guide a flange between said rolling lock member and said rib.
