Linearly actuated rotating handrail system for escalators and moving walkways

摘要

LINEARLY ACTUATED ROTATING HANDRAIL SYSTEM FOR ESCALATORS AND MOVING WALKWAYS, which comprises a handrail (8), with first friction means on one side, dragging means comprised of second friction means, configured for coupling to the first in such a way as to drag said band (8) in the displacement direction (D), and pressure means comprised of a first layer of kinematic support, formed by a crank (1), an articulated shaft (3), a driving connection rod (4), shafts (5) and driven cranks (6), and a second layer of friction means formed by traction rollers (7). The application of pressure to the worm band or handrail (8) and its balanced distribution over the different pressure rollers (2) is carried out by means of slides (11) actuated by a distributor (10) which is tightened by an elastic system (12) that transmits the tension by means of a beam (9).
