Channel-shaped sealing and finishing strips
First Claim
1. A channel-shaped sealing strip for straddling a flange or the like, comprisinga longitudinal channel-shaped gripping portion having a longitudinally extending rib on at least one internal wall of the channel and spaced from the base of the channel by a predetermined distance,a longitudinal sealing portion on and running along the outside of the gripping portion, the contacting surfaces of the sealing portion and the gripping portion being unconnected at their points of contact, anda longitudinal support which extends at least partially over the outside of the said one wall of the channel of the gripping portion and into the said channel, is spaced from and movable relative to the said one wall of the channel when the gripping portion is not straddling the said flange or the like, and has a longitudinally extending enlarged head which engages the distal edge of the said rib on the said one wall to hold the gripping portion and the sealing portion together,the said predetermined distance being such that the head is held on the said rib by the said flange or the like when the latter is embraced by, and has pushed home onto it, the gripping portion, thereby preventing separation of the gripping and sealing portions, the head being held spaced from the base of the channel.

Abstract
A sealing strip comprises a channel-shaped, metal reinforced resilient gripping portion, for embracing a flange or the like to be protected or sealed, and a longitudinally extending sealing portion running along the outside of the gripping portion. The sealing portion is attached to the gripping portion by means of a longitudinally extending support which is integral with the sealing portion and extends into the channel of the gripping portion. At its distal edge, the support has a head which locks onto a rib running along one internal wall of the channel near the channel base.

13. A channel-shaped sealing strip, comprising
a channel-shaped gripping portion made of metal carrier means of U-shape in cross-section and enclosed in flexible material, with the flexible material defining at least one rib running longitudinally along one internal wall of the channel adjacent the base thereof and a second rib running longitudinally along the opposite internal wall of the channel, a longitudinal sealing portion made of sponge rubber on and running along the outside of the gripping portion, the contacting surfaces of the gripping and sealing portions being unconnected at their points of contact, a longitudinal rubber support integral with the sealing portion and extending at least partially over the outside of the said one wall of the channel of the gripping portion and into the said channel towards the base thereof, and being spaced from the said one wall of the gripping portion, a longitudinally extending enlarged head on the support adjacent the base of the channel of the gripping portion, a flange extending into the gripping portion for protection and embracing thereby, the said head being held on the said one rib and between the latter and the base of the channel by the said flange, so as to prevent separation of the gripping and sealing portions, the head being held spaced from the channel base, and a longitudinally extending sealing lip integral with the said support and extending parallel to the said head but spaced therefrom by the height of the support so as to make contact with and seal against one of the sides of the flange and being angled relative to the flange so as to be directed away from the base of the channel.
