  • Articulated arm transfer device
    Patent number: 5577879
    Abstract: An articulated arm transfer device having a pair of upper arms and a pair of forearms. Each upper arm is rotatable at its shoulder end. Each forearm is rotatable at its wrist end. The elbow ends of the upper arms and the forearms are connected to each other by a link. The shoulder ends are mounted on a support in such a manner that one upper arm is rotated by a drive, and a holder for an object to be transferred is mounted on the wrist ends. The link includes shafts upon which the elbow ends are mounted. At least two S-bands connect the shafts in such a manner that rotation of one shaft in either direction causes rotation of the other shaft in the opposite direction. The elbow end of one upper arm is fixed to its shaft, while the elbow end of the other upper arm is rotatably mounted on its shaft.
