PURPOSE:To drive a staircase in simple and inexpensive manner by installing a means for reversing each revolution direction of the driving shaft of a gear driving system for driving a plurality of chains, as for a driving mechanism for a transport device in which the staircase is integrally connected, holding a stepping surface always horizontal. CONSTITUTION:A transport device is connected integrally by the left and right rails 01 and 01' and circulates, keeping a stepping surface 10 always horizontal In this case, the body of a staircase 1 is formed by a frame part 11 having the stepping surface 10 on the upper surface and the left and right bracket parts 12 and 12'. Further, at the bracket parts 12 and 12', the left and right wheels 13 and 13' placed on the rails 01 and 01', a pair of links 3, 3' and 4, 4' on the left and right sides which connect a staircase 2 which contiguously contacts on the outsides of the left and right skirt guard panels 05 and 05' in rotatable manner, and the left and right slatch holders 5 and 5' which are held in parallel to these links are installed. Further, each staircase 1, 2 is driven by a chain 6, and each revolution direction of an ascent and descent cycle driving shaft is set reverse by each external gear 106, 107. |
