Body trainer with holder and rotatable axis

摘要

Two body-connecting fastener belts etc (9,10) ae spaced out and mutually adjusted by means of two or more rods (11,12) to move the pivot axis or shaft (5) of the body holder (4) and/or the centre of gravity (13) between defined body attitudes with any movement of the users body (3). The shaft joined to the rods should run through the centre of gravity in certain or all body attitudes. The two rods can be so joined as to change the position of the shaft relative body or belts or rod positions. Where the rods are forcibly moved, the shaft coincides with the centre of gravity wherever this centre moves. One of the rods (11) may be hinged to the upper belt (9) as against rod (12) which is fixed or hinged to the bottom belt (10), the rods being hinged to one another via a guide.
