Abstract
Abstract A channel-shaped sealing strip comprises a channel-shaped metal core or carrier completely embedded in flexible plastics or rubber material which additionally defines gripping lips on the two opposite inside wall surfaces of the channel and running longitudinally along the strip. There are four relatively small such lips on one inside wall surface which are substantially equidistantly spaced from each other and the first or outermost one of which runs along the distal edge of its wall surface adjacent the mouth of the channel. There are two relatively larger such lips on the opposite inside wall surface. A soft rubber seal may be attached to the outside surface of the strip. The arrangement of the lips stabilises the strip against rocking or wobbling on a flange (e.g. a motor vehicle body flange around a door opening on which the strip may be mounted in use).

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
110 words
A channel-shaped finishing and sealing strip, comprising channel-shaped resilient material defining two opposite inside wall surfaces, a base and a mouth and having embedded within it a channel-shaped flexible reinforcing carrier, and lips attached to and running longitudinally along the strip and projecting inwardly from both opposite inside wall surfaces and inclined therefrom towards the base, there being four substantially equidistantly spaced relatively small lips on one said wall surface and two substantially equidistantly spaced relatively larger said lips on the other wall surface, one of the relatively smaller lips on the other of the wall surfaces being positioned along the edge of that wall surface adjacent the said mouth.
Claim 2
Dependent Claim
110 words
A channel-shaped finishing and sealing strip, comprising channel-shaped resilient material defining two opposite inside wall surfaces, a base and a mouth and having embedded within it a channel-shaped flexible reinforcing carrier, and lips attached to and running longitudinally along the strip and projecting inwardly from both opposite inside wall surfaces and inclined therefrom towards the base, there being four substantially equidistantly spaced relatively small lips on one said wall surface and two substantially equidistantly spaced relatively larger said lips on the other wall surface, one of the relatively smaller lips on the other of the wall surfaces being positioned along the edge of that wall surface adjacent the said mouth.
Claim 3
Dependent Claim
19 words
A strip according to claim 1, having a soft sealing member attached to and running along its outside surface.
Claim 4
Dependent Claim
151 words
A channel-shaped sealing strip, comprising a channel-shaped metal carrier, channel-shaped flexible plastics or rubber material completely embedding the carrier and defining gripping lips on the two opposite inside wall surfaces of the channel and running longitudinally along the strip, there being four relatively small such lips on one side wall surface which are substantially equidistantly spaced from each other and the first of which runs along the distal edge of that wall surface adjacent the mouth of the channel and there being two relatively larger such lips on the opposite wall surface, one of the relatively larger lips having its distal edge adjacent the distal edge of the second relatively small lip and the other of the relatively larger lips having its distal edge adjacent the fourth or innermost one of the relatively small lips, and a soft rubber seal attached to and running along the outside surface of the strip.
Claim 5
Dependent Claim
151 words
A channel-shaped sealing strip, comprising a channel-shaped metal carrier, channel-shaped flexible plastics or rubber material completely embedding the carrier and defining gripping lips on the two opposite inside wall surfaces of the channel and running longitudinally along the strip, there being four relatively small such lips on one side wall surface which are substantially equidistantly spaced from each other and the first of which runs along the distal edge of that wall surface adjacent the mouth of the channel and there being two relatively larger such lips on the opposite wall surface, one of the relatively larger lips having its distal edge adjacent the distal edge of the second relatively small lip and the other of the relatively larger lips having its distal edge adjacent the fourth or innermost one of the relatively small lips, and a soft rubber seal attached to and running along the outside surface of the strip.
