MOUNTAIN CLIMBER EXERCISING APPARATUS Russian patent published in 2005 - IPC

FIELD: sportive equipment, in particular, equipment for off-season exercising of mountain climbers.

SUBSTANCE: apparatus has variable resistance unit, sportsman's motion registration unit and motion parameter indication unit. Motion registration unit has base, platform built into bridge, and two U-shaped columns mounted and fixed on platform. Each of said columns is equipped with bar holder, which may be discretely repositioned and fixed on column by means of brackets. Bar holder has two chains attached with their one ends to top surface of bar middle part and with their other ends to lower surface of bar and thrown over two pairs of sprockets rotating on two pins and shaft. First pair of sprockets is fixed on shaft mounted on base by means of bushings with bearings. One of chains runs around fifth sprocket similar to said four sprockets and fixed in vertical plane on U-shaped column in its mid portion so as to be locked and around large-diameter sprocket, with pin of said sprocket being fixed on support. Lever with load fixed on its free end is put onto said pin. Lever may be fixed on large-diameter sprocket at different angles by means of spring-loaded finger and respective openings. Motion parameter indication unit has motion parameter measuring device including strain-measuring sensors incorporated in dynamometric platform built into platform, and linear motion and angular variation sensors (goniometers), connected through analog-to digital converter to personal computer. Bar rod has reduced weight, and ends of bar rod have reduced diameter. Receptacles are provided in chain unit for receiving of apparatus. Apparatus is further equipped with device for enabling mechanical connection of sportsman with light-weight bar rod and with step positioned on dynamometric platform.

EFFECT: wider operational capabilities for usage of apparatus in exercising of mountain climbers, increased efficiency in working out of mountain ascending and descending motions owing to selection of optimal loading mode in the course of performing motive actions.
