<p>A frame assembly comprising tubular frame portions (10) and (11) and end members (14) and (15) pressed therein. The end members (14, 15) each have a track engagement portion (16, 17) comprising an integral extruded flat web portion (20) bounded V- shaped edges (21). The inserted part of the end members (14, 15) have parallel ridges (22) providing permanent engagement on insertion. A frame member (23) includes a hollow box section (24) having a diagonal web (25) extending from each corner and supporting an integral flange (26). The included angles between the box section (24), the opposed surfaces of adjacent webs (25) and inner surfaces of the opposed flanges (26) define a track (30) into which the track engagement portions (16, 17) may slide. A single self-tapping screw (31) engages the track engagement portions (16, 17) and passes into the box section (24) at (32).</p> |
