Title:
DRIVING MECHANISM IN COUPLED CONVEYING APPARATUS
Document Type and Number:
WIPO Patent Application WO/1993/022231
Kind Code:
A1
Abstract:
A coupled conveying apparatus having steps (1, 2) is driven by a driving chain (6) circulatingly running along a running path (A, B... M, N, A) of a closed circuit, consisting of an ascending part, a descending part and a turning part for connecting the ascending part to the descending part. This coupled conveying apparatus has a follower medium, in which a multiplicity of thin plates (50) superposed one on another in a rockable manner are secured to a conveying frame. Then, this follower medium is engaged with teeth provided on either the upper side or the lower side of a chain link of a driving chain (6) provided on the ascending part (C-D) of the running path. The conveying frame receives a power transmitted through the follower medium from the driving chain (6), whereby the coupled conveying apparatus is circulatingly moved along said running path. On the other hand, there is provided a reversely transmitting mechanism (8, 90-92, 107, 108), in which a load imposed on the coupled conveying apparatus is converted into a turning motion, and, this turning force is reversed to be transmitted to a rotary shaft (105) for driving said driving chain (6).
