Four-bar linkage

Planar movement at its finest: A closed-chain dynamo called Four Bar takes center stage. Its simplicity leaves competition begging for attention. With just four interlocked components, we call them bars or links - no unnecessary clutter here, Four-Bar brings unity to a group of joints holding four loops. All this engineering know-how is cleverly tied together to yield efficient movement across planes parallel and synchronized, thus becoming known as the perfect mechanical harmony: A Planar Four-Bar Mechanism!
