Abstract
Roller-path system for the transportation of persons and goods, having an endless tread-plate band reversed around a horizontal axis as well as either a freely supported or a roller supported traction chain and self-supporting tread plates, each plate having two pull and two drag support-rod parts arranged close to the slate corners, respectively, opposite each other, where these plates can either directly support themselves, freely supporting rollers and the pull support-rod parts in addition to the traction chain, or can indirectly support themselves, having the pull support-rod parts mounted in traction chains with intermediate rollers and fork-shaped tread-plate resting elements which are attached by drag support-rod parts. The support-rod parts are provided as replaceably arranged system-adaptable pull and drag bolts.
