Abstract:
1. An outer chain link comprising: a first link plate including first and second end portions and a connecting portion interconnecting the first and second end portions of the first link plate; a second link plate including first and second end portions and a connecting portion interconnecting the first and second end portions of the second link plate, respectively: a first link pin connecting the first end portions of the first and second link plates together; and a second link pin connecting the second end portions of the first and second link plates together, the first and second end portions and the connecting portion of the first link plate defining a first outer peripheral edge located between opposite side surfaces of the first link plate, with the first outer peripheral edge including a first end edge section extending about the first end portion of the first link plate, a second end edge section extending about the second end portion of the first link plate and a pair of central edge sections extending along the connecting portion of the first link plate between the first and second end portions of the first link plate, the first and second end portions and the connecting portion of the second link plate defining a second outer peripheral edge located between opposite side surfaces of the second link plate, with the second outer peripheral edge including a first end edge section extending about the first end portion of the second link plate, a second end edge section extending about the second end portion of the second link plate and a pair of central edge sections extending along the connecting portion of the second link plate between the first and second end portions of the second link plate, the first end edge section of the first outer peripheral edge of the first end portion of the first link plate being dimensioned such that at least a part of the first end edge section of the first outer peripheral edge of the first end portion of the first link plate is disposed closer to the first link pin than a corresponding part of the first end edge section of the second outer peripheral edge of the first end portion of the second link plate, the first end edge section of the first end portion of the first link plate being non-semicircular, and the first end edge section of the first end portion of the second link plate being semicircular, the at least a part of the first end edge section of the first outer peripheral edge of the first end portion of the first link plate being disposed closer to the first link pin at a longitudinal axis of the first link plate than the corresponding part of the first end edge section of the second outer peripheral edge of the first end portion of the second link plate at a longitudinal axis of the second link plate.
