Abstract
An autowalk with individual step segments with a lower return travel coarse therefor, in which an elastic bridge closing the gap between step plates is provided between every two adjacent step segments.
Claims23
An autowalk comprising
- a plurality of individual step segments including step plates disposed with a gap between one another in a continuous arrangement defining an upper course adapted to carry people and a lower return travel course under said upper course, the step plates in the upper course being substantially at a comb mesh level in one horizontal plane,
- an elastic bridge respectively arranged between every two adjacent of said step segments bridging said gaps between said step plates respectively,
- each said bridge being below the comb mesh level when respective adjacent steps are in said upper course, said elastic bridge having means on said bridge and adjacent each lateral side thereof to prevent debris from spilling out sidewise, said bridge and said means forming a debris-catching pocket opening into said gap for catching the debris when it is in said upper course and said pocket being positioned so as to discharge the debris from said pocket at a predetermined position substantially where said upper course and said pocket turn upside down into said lower course.
An autowalk comprising
- a plurality of individual step segments including step plates disposed with a gap adjacent one another in a continuous arrangement defining an upper course adapted to carry people and a lower return travel course,
- an elastic bridge respectively arranged between every two adjacent of said step segments bridging said gaps between said step plates respectively,
- said bridge comprises a sealing member mounted on each adjacent edge of said step plates of said step segments below the comb meshing level,
- a separate of said sealing members are mounted on said each adjacent edge of said step plates, adjacent said separate sealing members elastically press against each other at least in said upper course.

- said step segments further include step plate carriers, said step plates are respectively mounted on said step plate carriers,
- every two said adjacent step plates have edges facing each other defining said gap therebetween,
- said bridge comprises a sealing member mounted on said step plate carriers, respectively, below each of said edges of each said step plates,
- a separate respective one of said sealing members is mounted on a facing edge of each said step plate carriers, and adjacent ones of said sealing members elastically press against each other at least in said upper course.
