ABSTRACT:
The chain is constructed of plastic modules connected in end to end relationship. It is claimed for all chain uses, including but not limited to use as a drive chain. Each individual module is without moving parts and, in most drive chain applications, has a cavity between its front and rear ends for receiving a tooth of a sprocket wheel. Each pair of adjacent modules has a transverse pin or pins extending from one module into a transverse pin-receiving socket or sockets of the other module so as to form a rotatable joint between the modules. Various means of constructing and joining the modules are disclosed. The plastic bicycle sprocket ring cluster which the plastic chain permits consists of stair-stepped multiple concentric rings of teeth which can be wider than a conventional bicycle chain now allows and which together can support each other by means of a common plastic infrastructure. The chain and cluster are light-weight and non-rusting; they can be also self-lubricating and colorful.
