ACCESSORY THAT VARIES LOAD IN VARIOUS PHASES OF MOTION

摘要

FIELD: sports. ^ SUBSTANCE: lever with its one end is fixed on hinged joint with horizontal axis of rotation and rests on roller or gear with axis of rotation, which is parallel to axis of hinged joint rotation. Axis of roller or gear rotation is fixed on weight and may move vertically. Pressure of lever weight on axis of roller or gear varies in process of weight motion. ^ EFFECT: provision of smooth variation of load in positive and negative phases of lever motion. ^ 5 dwg
