Abstract:
A stepping exerciser comprising:a base having an upright tubular member disposed thereon, said tubular member having lower and upper left and right portions, each of said lower left and right portions being formed with a circumferentially extending slot, each of said upper left and right portions having a pivot arm extending radially therefrom;a rotary member disposed inside said tubular member and rotatable relative to said tubular member about an axis of said tubular member, said rotary member having a pair of force transmitting rods that extend outwardly of said tubular member through said slots in said lower left and right portions of said tubular member, respectively;a pair of pivot couplers, each of which is sleeved rotatably on said pivot arm of a respective one of said upper left and right portions of said tubular member, and each of which has a movement driving rod that extends downwardly therefrom and that abuts against a respective one of said force transmitting rods;left and right pedal arms, each of which has a rear end, and a front end connected to a respective one of said pivot couplers such that downward pivoting movement of one of said pedal arms relative to said tubular member causes said movement driving rod on the respective one of said pivot couplers to push the respective one of said force transmitting rods for rotating said rotary member axially inside said tubular member, and causes the other one of said force transmitting rods to push said movement driving rod on the other one of said pivot couplers for upward pivoting movement of the other one of said pedal arms relative to said tubular member;a pair of resistance cylinders, each of which interconnects said base and said rear end of a respective one of said pedal arms to provide resistance to pivoting movement of the respective one of said pedal arms relative to said tubular member; anda counting device including a display unit mounted on said base for generating a count output corresponding to amount of exercise performed when said stepping exerciser is in use.
