  • Four-bar linkage - Wikipedia

    A four-bar linkage, also called a four-bar, is the simplest movable closed-chain linkage.It consists of four bodies, called bars or links, connected in a loop by four joints. Generally, the joints are configured so the links move in parallel planes, and the assembly is called a planar four-bar linkage.Spherical and spatial four-bar linkages also exist and are used in practice.
