<p>Accelerated walkway, with a moving surface (7) comprising sets of treadboards, each set being formed by a front treadboards (8) and a rear treadboard (9), articulated to each other along an axis perpendicular to the direction of movement. The rear treadboard (9) of each set comes mounted on lateral guides and chains whilst the front treadboards is related with the rear treadboard of the set of treadboards located immediately in front. The chains are formed by elbowed and straight links and are run between lateral guides which produce the swivelling of the links. The walkway includes portions for entrance (1) and exit (2), in which the treadboards circulate at slow speed, a centre portion (6) in which the treadboards circulate at high speed, and two transitional portions (4 and 5) in which the treadboards are accelerated and retarded due to the folding or unfolding of the side chains. <IMAGE></p> |
