In a method for determining the elongation of segments of a chain of a chain drive during operation, a plurality of measured values is determined at different positions of the chain. A plurality of length values is determined from the plurality of measured values and the length values are assigned to the segments of the chain, with the length of the segments of the chain being smaller than the length of the chain.

A bicycle chain comprises a first outer link plate. The first outer link plate comprises a first outer-link end portion, a second outer-link end portion, a first outer-link intermediate portion, and a first outer-link longitudinal centerline. The first outer-link end portion, the second outer-link end portion and the first outer-link intermediate portion define a first outer-link outer peripheral edge. The first outer-link outer peripheral edge comprises a first outer-link end edge, a second outer-link end edge, and a pair of first outer-link intermediate edges. A first radial distance is defined from a first outer-link center axis to the first outer-link end edge in a perpendicular direction. A minimum distance is defined between the pair of first outer-link intermediate edges in the perpendicular direction. The minimum distance is smaller than 200% of the first radial distance and is equal to or larger than 5 mm.

A mechanical system with a double-sided chain, composed of a driving wheel (S1), a tensioner wheel (S2) for the chain (1), a driven wheel (S3) and a chain (1), which winds around the wheels (S1) and (S2), and engages the wheel (S3) on its outer side, characterized in that the wheel centres (S1), (S2) and (S3) are not collinear, whereas the position of wheel axis (S2) in relation to wheel axis (S1) and (S3) determines the line of operation of chain (1) and determines the optimal angle alpha between the direction of the force vector F and the perpendicular to the straight line joining the centres of tensioner wheel (S2) and driven wheel (S3), and passing through point (B) where force F1 is applied. while the value of the angle alpha is equal 15 degrees.

Improved L-shaped bracket member of a pair of oppositely disposed back-to-back mirror image bracket members configuring when mounted, an improved replacement link chain for repair of a disconnected chain link drive mechanism, including a base flange mountable by bolt fastener to a substrate member carrying the chain link mechanism, and a perpendicularly depending side flange being of generally flat thickness dimension to define improved uniform gap opening between a pair of oppositely mounted side flanges of the pair of bracket members, and having an aperture extending through the thickness dimension of the side flange positioned with the aperture opening thereof disposed in at least tangential interference with the rotational radius of the bolt fastener to enable the rotating bolt to extend into the aperture opening to remove striking of the bolt with the adjacently disposed side flange when mounting or dismounting the base flange of the improved bracket member.

A flat cable assembly has a belt-like portion. In the belt-like portion, cables capable of transmitting power and/or signals and a pair of tubular portions positioned at the opposite ends in the width direction are arranged in parallel with one another. Each tubular portion has a longitudinal multi joint supporting member inserted therein in a state where link members are arranged in series, and adjacent link members are pivotally connected to one another. The multi-joint supporting members are configured to limit pivoting motion in a first direction that intersects the longitudinal direction in a range to a previously defined bend radius, and to restrict flexing in a second direction that is opposite from the first direction.
