<p>A tread for mounting a wheelchair or the like consists of three continuous treadboards (1, 2 and 3). The treadboards (1 and 3), which are disposed in front and at the back of the central treadboard (2) are each constituted by main bodies of treadboards (10, 30) and floating treadboards (11, 31) which are separated from the main bodies of treadboards (10, 30). During normal running of an escalator, the main bodies of treadboards (10, 30) and the floating treadboards (11, 31) are joined to each other and run integrally in the same manner as a regular escalator. When a wheelchair or the like is mounted thereon, the floating treadboards (11, 31) are joined to the central treadboard (2) and the floating treadboards (11, 31) are integrated and move in the form of one and the same plane, so that a wheel chair or the like can be mounted thereon.</p> |
