Abstract:
1. A chain link comprising: a substantially planar outer circumferential area; first and second side flanks disposed on opposite sides of the link, substantially perpendicular to the outer circumferential area, and separated by a link width greater than a width of the outer circumferential area; a first planar bevel area joining the outer circumferential area and the first side flank, inclined under a oblique bevel angle of 10° to 30° relative to the first side flank in the direction towards the second side flank; a second planar bevel area joining the outer circumferential area and the second side flank, inclined under the oblique bevel angle relative to the second side flank in the direction towards the first side flank; and a rounded inner circumferential area facing an inside opening of the link including a semi-circular planar area, the semi-circular planar area joined to both the first and the second side flanks tangentially; wherein the first planar bevel area opens in a laterally offset manner in relation to the first side flank into the outer circumferential area at a bevel distance of 0.02 to 0.15 times the link width, and the second planar bevel area opens in a laterally offset manner in relation to the second side flank into the outer circumferential area at the bevel distance.
