Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
213 words
In combination, a plate member having a supporting edge, a grooved member having a groove of greater width than the thickness of said plate member for receiving said edge and a clamping insert for gripping the sides of said plate member at said supporting edge and for insertion with said supporting edge into said groove, said insert comprising an elongated body of elastomeric material having a central portion and side portions, said side portions having locking flanges extending outwardly from the outer faces and ribs extending inwardly from the opposing inner faces for engagement with the sides of said plate member, the thickness of said side portions and said ribs being greater than the difference between the width of said groove and the thickness of said plate whereby said ribs are compressed into gripping engagement with the sides of said plate, said groove having an end and sides with slots in the sides of said groove for engaging said locking flanges of said side portions of said clamping insert in locking engagement in said slots and said elastomeric material being stretchable whereby said clamping insert may be elongated to reduce the thickness of said side portions including said ribs to compensate for dimensional variations of the plate member, grooved member and clamping insert.
Claim 2
Dependent Claim
213 words
In combination, a plate member having a supporting edge, a grooved member having a groove of greater width than the thickness of said plate member for receiving said edge and a clamping insert for gripping the sides of said plate member at said supporting edge and for insertion with said supporting edge into said groove, said insert comprising an elongated body of elastomeric material having a central portion and side portions, said side portions having locking flanges extending outwardly from the outer faces and ribs extending inwardly from the opposing inner faces for engagement with the sides of said plate member, the thickness of said side portions and said ribs being greater than the difference between the width of said groove and the thickness of said plate whereby said ribs are compressed into gripping engagement with the sides of said plate, said groove having an end and sides with slots in the sides of said groove for engaging said locking flanges of said side portions of said clamping insert in locking engagement in said slots and said elastomeric material being stretchable whereby said clamping insert may be elongated to reduce the thickness of said side portions including said ribs to compensate for dimensional variations of the plate member, grooved member and clamping insert.
Claim 3
Dependent Claim
50 words
The combination of claim 1 wherein said locking flanges are tapered inwardly toward said central portion so that the entering width of said clamping insert is approximately the same as the width of said groove for ease of movement of said grooved member over said insert and said plate member.
Claim 4
Dependent Claim
26 words
A clamping insert according to claim 1 wherein each of said side portions has two ribs on each for gripping the sides of said plate member.
Claim 5
Dependent Claim
45 words
A clamping insert according to claim 1 wherein said body of elastomeric material is formed with said ribs on one of said side portions and on the other of said side portions being spaced apart a distance less than the thickness of said plate member.
