Patent ID: 7278535

Claim:
Chain link, which may be assembled with other chain links to form a conveyor belt, wherein the link comprises a top side and a bottom side defining a thickness there between, a front edge end a rear edge wherein along the front and rear edges, recesses are provided such that a recess along one edge corresponds to no recess at the opposite edge, and that the recesses along one edge inside each recess is provided with two notches protruding into the recess along a common axis parallel to the front/rear edges, and that apertures are provided inside the recesses along the opposite edge, where the apertures can accommodate notches from an adjacent chain link, and that an opening substantially perpendicular to the bottom and top sides connects the aperture with the bottom side for allowing the notches to pass into the aperture, and that the notches have a circular cross-section with a diameter y, parallel to the intended travelling direction of the conveyor belt, and that the corresponding aperture has an extent in the intended travelling direction, substantially corresponding to y, and that the opening has an extent in the intended travelling direction, substantially corresponding to or smaller than y, and that the centre of the notches are in the same plane in relation to the top side as the centre of the apertures, wherein the distance between the front edge and the rear edge is x, and that the extent of the recesses in the intended travelling direction of the conveyor belt is at least 50% of x.
