APPARATUS FOR EXERCISING OF WEIGHT-HANDLING EVENT SPORTSMEN Russian patent published in 2004 - IPC

FIELD: sportive equipment for special exercising of sportsmen engaged in weight-handling sport events.

SUBSTANCE: apparatus has variable-resistance unit and movement parameters registering and indicating unit. Variable-resistance unit has base with built-in bridging and two U-shaped poles mounted on base. Bar holder is provided on each of said poles and adapted to be discretely repositioned and secured on pole by means of bracket. Bar holder is equipped with two chains attached with their one ends to bar rod top side and with their other ends to bar rod bottom side. Chains are thrown over two pairs of sprockets positioned for rotation on two pins and on shaft. First pair of sprockets is fixed on shaft mounted by means of bushings with bearings on upper cross-pieces of U-shaped poles and second pair of sprockets is mounted on two pins fixed by means of bushings with bearings on base. One of said chains runs around movable fifth sprocket similar to said four sprockets movably positioned in vertical plane on mid portion of U-shaped pole so as to be fixed, and around large-diameter sprocket, whose pin is secured on support mounted on base. Lever with weight is movably put onto support, said weight being secured to free end of lever, which may be fixed at different angles by means of spring-loaded finger on large-diameter sprocket. Support is provided with respective openings. Movement parameters registering and indicating unit is comprised of movement parameter measuring unit including strain-measuring sensors made integral with dynamometric platform built into bridging, and linear movement and angular variation sensors (goniometers). Movement parameter measuring unit is switched through analog-to-digital converter to personal computer. Bar rod of apparatus is made light-weight and has reduced diameter at its ends. Chain attachment includes respective receptacles for mounting thereof. Apparatus is further equipped with two devices allowing attachment of two weights on light-weight bar rod and rotation of said weights at an angle individually suitable for sportsman.

EFFECT: wider operational capabilities and increased efficiency in exercising of sportsmen owing to selection of optimal loading mode during doing motion exercise.
