Patent ID: 8234852

Claim:
A chain link for an anti-skid chain, the chain link having an essentially oval shape, the chain link comprising: an upper side wall, a lower side wall, and a longitudinal central axis that bisects the chain link into upper and lower halves, wherein the upper side wall, the lower side wall, and the longitudinal central axis lie in a central plane of the chain link, the central plane bisecting the chain link into a left half and a right half, the left half lying on a left side of the central plane and the right half lying on a right side of the central plane, wherein the chain link has a cross section with an inner cross-sectional area proximal to the longitudinal central axis and an outer cross-sectional area distal to the longitudinal central axis, the outer cross-sectional area having an outer surface having an approximately arcuate shape, the inner cross-sectional area comprising a flat side extending on both of the left side and the right side of the central plane, the flat side being oriented essentially perpendicular to the central plane of the chain link, the inner cross-sectional area further comprising, on each of the left side and the right side of the central plane, a first edge that defines a boundary between the outer cross-sectional area and the inner cross-sectional area, a second edge that defines a boundary of the flat side, and a chamfered area located between the first edge and the second edge, wherein the chamfered area is oriented at an angle to the central plane, the angle having a value less than 90°.
