<p>A tambour door has a plurality of vertical laths (9) interconnected edge-to-edge in a manner allowing the door to move around corners. The door is suspended from an overhead track (3,17,23), each lath (9) having a runner (5,19,24) which engages that track, while at the bottom each lath (9) has a runner (13,19,24) co-operating with a track (11,17,23) directly below the overhead track. Both tracks (3,11;17) can be identical. The runners can embrace the tracks (3,11) or engage within them (17), and to negotiate curves while not being too loose on the straights the runners (24) may have protuberances (25) spaced longitudinally of the track (23) and providing the only lateral contact. <IMAGE></p> |
