SHOULDER EXERCISING DEVICE

摘要

The shoulder exercising device comprises two actuating arms (40) which are movable vertically and pivotable about horizontal axes (30) which are aligned with shoulder joints of the user. Each arm (40) is secured by a bearing sleeve (42) to a pinion gear (45) in meshing relation with a rack gear (65) such that movement of each arm (40) in each direction is resisted by a double-acting hydraulic cylinder (70) equipped with valves to provide precise resistance to each of the arms in each direction toward and away from a median plane P.
