“…in arm supports and robotics applications). In linkage-based balancers, adjustment of the balancer characteristics is possible in a number of ways, and (patent) the literature describes several methods, where the initial tension of the springs is increased [7,8], the positions of certain pivot and attachment points are (automatically) adjusted [6,9,10], or the spring stiffness is altered [11]. In all the described statically-balanced systems or constant force generators, however, the adjustment requires significant mechanical work as the spring lengths and tensions change.…”

Static balancing is a useful concept to reduce the operating effort of mechanisms. Spring mechanisms are used to achieve a constant total potential energy, thus eliminating any preferred position. Quasi-statically, the mechanism, once statically balanced, can be moved virtually without the operating energy. In some cases, it is desirable to adjust the characteristic of the balancer, for instance, due to a change in the payload in a gravity balanced mechanism. The adjustment of current static balancers requires significant operating energy. This paper will present a novel variant to adjust the spring-and linkage-based static balancers without the need for external energy. The variant makes use of the possibility to adjust the spring stiffness in an energy-conserving way by adjusting the number of active coils. The conditions under which it functions properly will be given, and a proof of the concept model will be shown.
