Abstract: A coupling mechanism controls the location of the central primary draft load transmitting fixed-length link independently of the coupler. The coupling mechanism allows for translation in at least three orthogonal directions and for rotation of two distinct planes between coupled components, thereby providing a means for lateral shifting and articulation. The coupling mechanism mitigates unexpected rotation by restricting rotation along a longitudinal axis of the fixed-length link. Rotation of the coupling mechanism is furthermore controlled by means of a indexing turntable. The orientation and the position of the coupling mechanism is therefore determinant and predictable.

Abstract: This invention in the field of weightlifting assists a weightlifter in training more effectively, by providing an apparatus for decreasing weight during a weightlifting movement, such that more weight is lifted initially than must be set down again afterward. The apparatus consists generally of an arm extending from a hinge anchored at a fixed height, such that the arm may be placed atop a bar or barbell to be lifted. When the bar is lifted, the arm's position relative to the hinge causes the arm to fall off of the bar and remove the weight of the arm from the weight being lifted by the weightlifter. Thus, the amount of weight the weightlifter is lowering back down again is reduced compared to the amount of weight the weightlifter initially lifted.
