US Patent 9103147 Synchronized multiple-angle rotatable dual-pivot structure

A synchronized multiple-angle rotatable dual-pivot structure includes a first pivot, a second pivot, a plurality of connection members, and a support frame. The first pivot and the second pivot are each provided with an installation slot. The connection members are of the same length and each has two ends respectively and movably mounted in the installation slots of the first pivot and the second pivot. The support frame has two ends respectively coupled to the first pivot and the second pivot. The connection members are connected between the first pivot and the second pivot so that when one of the first pivot and the second pivot is rotated, forces are induced between the first pivot and the second pivot to mutually pull and push each other so that synchronized rotation can be achieved in an easy and effortless manner and the rotation angle can reach at least 180 degrees.
