An inner link plate for a bicycle chain is provided. The inner link plate may have a longitudinal centerline defining a longitudinal direction and comprising a first inner-link end portion including a first inner-link opening having a first inner-link center axis, a second inner-link end portion including a second inner-link opening having a second inner-link center axis parallel to the first inner-link center axis, and an inner-link intermediate portion interconnecting the first inner-link end portion and the second inner-link end portion. The first inner-link end portion may have an extended edge portion extending to be away from the second inner-link end portion in the longitudinal direction.

A bicycle chain comprises a first outer link plate and a second outer link plate. A first outer-link longitudinal axis extends through a first outer-link center axis and a second outer-link center axis to divide a first outer surface into a first side and a second side when viewed in an axial direction. A second outer-link longitudinal axis extends through a third outer-link center axis and a fourth outer-link center axis to divide a second outer surface into a third side and a fourth side when viewed in the axial direction. The fourth side includes a first circumferential area and a first chamfer free area. The first circumferential area has a first angle equal to or larger than 20 degrees. The first chamfer free area is adjacent to the first circumferential area. At least one second chamfer is provided outside the first chamfer free area.

An interlocking camera mount uses multiple interlocking links to form an articulated chain of camera mounts. To accomplish this, each interlocking link has a camera mount, and two pivotable bases. The camera mount is an attachment point to which a camera can be affixed. The pivotable bases are connection mechanisms that enable the interlocking links to be chained together and form an articulated chain. Additionally, the pivotable bases are positioned on opposite sides of the camera mount. Thus, facilitating the creation of a serially linked chain. Specifically, the pivotable bases of an arbitrary link are used to connect the arbitrary link to one or more adjacent links.

A curling effect is provided via a system, which may be included in an article, via a plurality of links, including distal, proximal, and intermediary links, that each comprise: a base; first and second wings, connected to opposite sides of the base such that each of first and second through-holes are aligned at a first height; and a header, connected between the wings that defines a third through-hole at the first height and a fourth through-hole at a second height different from the first height that is configured to accept a stringer there-through so that a force applied on the stringer in a direction from the distal link towards the proximal link causes rotation of neighboring links relative to one another; the neighboring links being joined via a linking axel disposed on a shared axis through the first, second, and third through-holes of the neighboring links.

A drive chain (2a, 2b) for a chain drive comprises a plurality of chain links (10, 20) and joints (30) respectively connecting two of the chain links (10, 20) forming the drive chain (2a, 2b). The drive chain (2a, 2b) further comprises a plurality of carrier elements (40), each of said carrier elements (40) being linked to one of the chain links (10, 20) or joints (30) and supporting at least two support/engagement elements (43, 44), which are configured for supporting the drive chain (2a, 2b) and/or for engagement with an appropriate turnaround element (50; 90) for driving the drive chain (2a, 2b).
