Sealing or trimming strip structure

Claim 1

A trimming or sealing strip structure comprising at least two mutually inclined channel-shaped portions each defined by first and second parallel and opposed side wall with a base between them, the two portions being mutually positioned and having respective ends mutually shaped to form a mitered joint between the two said portions with one end of each of the first and second side walls and the base of one channel-shaped portion being in contact with, respectively, one end of the first and second side walls and the base of the other channel-shaped portion, the channel openings of the two portions facing outwardly of the mitered joint, each said channel-shaped portion comprising carrier means of relatively rigid material defining a U-channel and channel-shaped flexible covering material covering the carrier means, the flexible covering material being free of the relatively rigid material of the carrier means in the marginal regions running along the outer edges of the side walls of the channel-shaped portions, and two longitudinal reinforcing members of substantially rigid material each embedded in a corresponding outboard peripheral part of the said marginal region of a respective one of two said first side walls, the reinforcing members each lying parallel to the outboard surfaces of the channel in which they are respectively embedded and extending along the said regions to the contacting ends of the said first side walls and there meeting each other proximate the outboard portion of the corner which said mitered joint forms whereby the flexible covering material at said outboard portion is stiffened.
