ANTRIEBSEINRICHTUNG FUER DIE FINGER EINER KUENSTLICHEN HAND

摘要

An artificial hand having at least one finger and a thumb is provided with a drive motor and a gear to open and close the finger and thumb. A gear wheel is secured to each joint where the finger and thumb is connected to the hand proper. A motor driven worm gear meshes with both gear wheels and reversible gears are interposed between the motor and the worm gear, whereby an axially displaceable shaft maintains the interconnection between the drive means and the worm gear.
