Patent ID: 8240452

Claim:
A tread element for a conveyor movable in at least one travel direction which tread element comprises a tread plate with a tread surface and a strip at least one region of the tread surface, wherein a guiding and fixing arrangement with a first element in the form of a groove and with a second element in the form of a key engaging the groove is provided, wherein one of the elements is provided at the tread plate and the other of the elements is provided on the strip and the two elements co-operate in order to prevent movements of the strip relative to the tread element perpendicularly away from the tread surface, characterized in that a first abutment arrangement is provided, with first tread element abutment surfaces at the tread plate and complementary first strip abutment surfaces at forward ends of groove projections of the strip, the first abutment arrangement providing guidance for the for the connection between the tread plate and strip and not providing a locking function between the tread plate and strip, a second abutment arrangement is provided, with a second tread element abutment surface at the tread element and a second strip abutment surface at a locking projection of the strip, the second abutment arrangement providing a locking function between the tread plate and strip, wherein the first and the second abutment arrangements are spaced laterally from each other, engage through relative motion of the strip in a plane parallel to the tread surface, and each is oriented and arranged to prevent movements of the strip relative to the tread element, and the strip has a resiliently deformable strip body for bending during mounting such that the strip abutment surfaces thereof come into contact with the respectively complementary tread plate abutment surfaces.
