Utilizing force resistance generated by user only:
(under subclass 92) Subject matter wherein the human user applies the operating pressure against pressure opposing structure which derives its opposing pressure solely from another part of the body of the user.
(1) Note. The resisting force is normally derived from a muscle contraction. Specifically included herein is a self-manipulated device wherein a self-applied stress, i.e., a force applied by a muscle, is resisted by a force that originates passively from strain, i.e., deformation resulting from the force, within the body of the user, e.g., by stretching of the body, etc. The parts of the body are pitted against each other in direct one-to-one relationship via a mechanical motion transmission means. This distinguishes from the apparatus of subclasses 122+, for example, where a spring is an intermediate component.
SEE OR SEARCH THIS CLASS, SUBCLASS:
91, for isometric force resisting apparatus having dynamically stationary pressure opposing structure and wherein the pressure of the user does not change that state. See the (1) Note under that subclass.
122+, for a resilient force resisting apparatus also utilizing a user supplied counter force.
133+, for a frame which supports both the user and force resisting apparatus while force exerted by the user is transmitted through the frame and wherein details of the force resistance apparatus are not claimed.
139, for a user interface element wherein details of the force resistance apparatus are not claimed.
