Abstract
A tread element (12) for a passenger conveyor (10); the tread element (12) comprising a tread (14) defined by a front side, a rear side, a first lateral side and a second lateral side; a riser (16) comprising a riser panel (18) adjacent the rear side of the tread (14) and pivotably connected to the tread (14); at least one tread chain axle (28) adapted to connect the tread element (12) to the at least one tread chain (22); at least one tread roller (42) adapted to engage with a guide element (36) of the passenger conveyor (10) to adjust the position of the tread (14) with respect to the riser (16); and at least one cantilever arm (40) supported at its one longitudinal side by the tread chain axle (28) and supporting the tread roller (42) at its opposite longitudinal side.
Claims20
A tread element for a passenger conveyor;
- the tread element comprising
- a tread defined by a front side, a rear side, a first lateral side and a second lateral side;
- a riser comprising a riser panel adjacent the rear side of the tread and pivotably connected to the tread;
- at least one tread chain axle adapted to connect the tread element to at least one tread chain;
- at least one tread roller adapted to engage with a guide element of the passenger conveyor to adjust the position of the tread with respect to the riser;
- and
- at least one cantilever arm comprising a hole or recess for connecting to the at least one step chain axle in a torque proof manner so that the at least one cantilever arm is supported at its one longitudinal side by the tread chain axle, the at least one cantilever arm supporting the tread roller at its opposite longitudinal side;
- wherein a distance (L) between the tread chain axle supporting the at least one cantilever arm and the tread roller supported by the same cantilever arm is larger than a distance (X) between the tread chain axle of the tread element and the tread chain axle of an adjacent tread element in the endless tread chain of a people conveyor.
