Abstract
An artificial elbow joint comprises a detent wheel rotatably mounted on the forearm and fixedly connected to the upper arm, the detent wheel having a periphery defining a series of detent notches and a lug affixed thereto and projecting from the periphery. A latch is slidably mounted in relation to the detent wheel and a spring biases the latch against the detent wheel into a first position wherein the tip of the latch engages a respective detent notch to lock the joint. A cable line is attached to the latch and is operable to move it into a second position wherein the latch tip is disengaged and the joint is unlocked, operation of the cable line pivoting the forearm in relation to the upper arm. A leaf spring having an angularly bent end is displaceable between the notched detent wheel periphery and the latch by the lug to retain the latch in the second position.
