Aktor

DE 102009017503 A1 UPAB: 20101101 NOVELTY - The actuator (8,8') with a rotating shaft (1'), to wind and unwind cables (S1,S2) to move an object towards or away from it, has at least one deflection unit (7) at an orthogonal gap from the shaft and with axial movement in relation to the shaft and in an orthogonal projection between the two cable anchor points(5,6). One end of a third cable is secured at one anchor point and the end of a fourth cable is fixed at another anchor point. Their other ends work with the first and/or second actuator unit. A second deflection unit (9), diametrically opposite the first, is for winding and unwinding the third and fourth cables. USE - The actuator is for moving an object in relation to a fixed anchor e.g. for grippers, levers, flaps, slides and the movement of mechanical prostheses. (All claimed). ADVANTAGE - The system gives a bi-directional actuation, taking up loads in a robust structure. It can be integrated into complex mechanical systems to give locomotion and robotic movements
