Abstract: Remote control of a mechanical transmission, more particularly to the remote control of at least one gripping element by a monodirectional action, whereby the gripping element includes an articulation which can close by converging upon the object which is to be gripped and which can be locked in an active position upon contact with said object and the control device can be disengaged in the gripping position.

Abstract: A hand prosthesis or artificial hand with soft gripping having a palmar part made from a flexible material, and an attached dorsal part formed from a rigid material having a base plate having a dorsal face, and a palmar face forming a palm of the hand, and fingers detachably attached to the base plate on its dorsal face, with each finger having ball joint elements; a return spring is connected to a hook and passes internally through the joints over dorsal facing sides of pins, tubular guides are supportedly mounted and attached to the internal walls of the joints, traction spring segments in the tubular guides have spaced portions between ends of succeeding segments with the spaced portions occurring in zones of the ball joint elements, a traction cable is connected to the hook and guided internally of the joints and passes through the tubular guides within the traction spring elements, a yoke is connected to a single traction cable to balance forces and divide the force from the single traction cable into fo
