<p>A corner junction assembly (20) for use with two adjacent lengths of blind track (10) has a bearing ring means (22) making a captive frictional fit in a bearing hub means (24) to permit relative rotation of those two parts. The corner junction assembly (20) comprises track engagement means (40, 70) connected to respective ones of the bearing ring means (22) and the bearing hub means (24) and adapted to be connected to the ends of the adjacent lengths of the tracks (10). The corner junction assembly (20) also comprises movement transmission means (16, 106) for transmitting movement from a traveller control means (16, 18), such as a control cord or rod, in one of the lengths of track to a traveller control means in the other length of track.</p> |
