Abstract
A conveyor chain which is designed to be used on a stepmill to form into steps on the side interacting with a user, but which can fold into a generally flat configuration when returning to the top of the tread. Each step is designed to be formed of four generally identical segments where both the segments forming the tread and kickplate can fold relative to each other and each of the tread and kickplate can fold at a midpoint between two segments.
Claims17
A conveyor chain for a stepmill, the chain comprising:
- a plurality of segments, each of said segments comprising a main body including:
- a top surface;
- a bottom surface smaller than said top surface and generally parallel thereto;
- an angled face interconnecting said top surface and said bottom surface;
- and
- an edge also interconnecting said top surface and said bottom surface;
- wherein, said edge and said angled face are not parallel to each other;
- and
- wherein said edge has a plurality of eyelets arranged thereon;
- and
- a plurality of axial rods;
- wherein, said plurality of segments are arranged into a conveyor chain by:
- forming multiple units from said plurality of segments by repeatedly connecting a segment to another segment with a hinge arranged so that said angled faces of said segments can alternatively be in contact with each other and not in contact with each other;
- interconnecting said multiple units into a chain by threading an axial rod through interleaved eyelets from adjacent units.

- and
- said tread and said kickplate are positioned generally perpendicular to each other.
