MUSCLE EXERCISING APPARATUS Russian patent published in 2001 - IPC

FIELD: sportive equipment. SUBSTANCE: apparatus has user accommodating movable device with actuating mechanism, loading device with flexible tie-rod whose one end is coupled to actuating mechanism, and device for adjusting loading in percentage of weight to be lifted. User accommodating device is mounted on one or two columns. Other end of tie-rod is adapted to carry user accommodating device and load adjusting device mounted on user accommodating device. Load adjustment is provided by regulating tie-rod end strokes ratio. Tie-rod end connected to actuating mechanism may be passed through roller or rollers mounted on column base. Tie-rod ends stroke ratio is determined from formulas: (a) during passage of tie-rod end connected to actuating mechanism through rollers on column base: i=P/T+1, where T is force to be applied to actuating mechanism; P is total weight of user accommodating device and load adjusting device; (b) column base is free from rollers: i=P/T-1; (c) apparatus is used in mode when user is beyond user accommodating device, i.e. load P does not involve user's weight, regardless of usage of rollers on column base: i=P/T. Seat of user accommodating device may be detached and bracket may be mounted instead of it. Bracket may be equipped with pin for attachment of replaceable devices adapted for specific exercises. EFFECT: increased efficiency, wider operational capabilities and simplified construction. 2 cl, 3 dwg
