Abstract

An inner link plate is provided for a bicycle chain. The inner link plate has a longitudinal centerline, an inside surface arranged to face another inner link plate when the chain is assembled, an outside surface opposite to the inside surface, and an outer peripheral edge disposed between the inside and outside surfaces. The bicycle inner link plate basically has a first end portion, a second end portion and a connecting portion. The first and second end portions are each provided with a connecting opening. The connecting portion includes a recess disposed on the inside surface of the connecting portion. The recess has a maximum longitudinal width on the outer peripheral edge, and a minimum longitudinal width in a region adjacent the longitudinal centerline. The recess at least extends from the outer peripheral edge to the longitudinal centerline.

Description

technical field [0001] The present invention generally relates to a configuration for an inner link plate of a bicycle chain. More particularly, the present invention relates to an inner link plate for a bicycle chain used in a bicycle that shifts between sprockets to change gears. Background technique [0002] Most bicycles have a drive train that uses a chain to transmit the pedaling action from the rider to the rear wheel. A bicycle chain has a plurality of inner links and a plurality of outer links interconnected in an alternating fashion by a plurality of pins. Typically, each inner link comprises a pair of parallel inner plates connected by a pair of parallel hollow cylinders or pins surrounded by cylindrical rollers. Each outer link includes a pair of parallel outer plates connected by pins of adjacent inner links. To form a single continuous chain, two inner links are joined together by releasable connecting links commonly called master chain links. [0003] In r...
