Abstract: A magnetic adjustable braking device comprises a rotating housing, a magnetic conductor ring, a shaft member, a positioning device, a sliding housing and a driving device. The effective coupling area between the permanent magnetic and magnetic conductor ring can be adjusted and varied to provide variable braking torque (load) of the sporting device. This braking device has a compact size for easily applying it to different sporting equipment.

Abstract: A improved mechanism of a stepping device includes a pedal mechanism constructed by a parallelogram which facilitates the pedal remains at a horizontal position at all levels. A trasnaxle is rotated as the pedal is stepped down and a gear and an actuating gear are used to connect a load adjusting device. Then a predetermined load can be applied to the pedal as it moves down. A one-way bearing is disposed inside the bushing of the transaxle, hence the pulley disposed thereof can rotate bi-directionally. A pulling rope and a spring are used to pull up the pedal which moves to a lower dead point. While the inertia of the gear and actuating wheel will make it moves continuously. By this arrangement, a smooth and continuous stepping device is provided.

Abstract: A torque variable exercising apparatus includes a frame, a first cable-and-pulley arrangement and an impeding mechanism. The first cable-and-pulley includes a first cable having one end fixed to the frame and a second end incorporating an operating handle. The first cable moves up and down to pass a series of fixed pulleys and a first movable pulley. The impeding mechanism includes a second cable-and pulley arrangement mounted on the frame and connected to and suspending the first movable pulley, a vertical stand and a lever arm pivotally mounted on the vertical stand and having a first end connected to the second cable-and-pulley arrangement and a second end of the lever arm carrying a weight. The operating handle can be operated to apply a force at the first end of the lever via the second cable-and-pulley arrangement.

Abstract: An exerciser for exercising arms includes a frame assembly and an input mechanism which has a pull rope. The pull rope has a fixed end and a movable end connected to an arm exercising mechanism. A suspended pulley set includes a pulley seat on which an upper pulley and a lower pulley are mounted. The pull rope extends around the upper portion of the lower pulley, while a guide rope extends around the lower portion of the upper pulley. The guide rope is fixed on the frame assemby at an end thereof. When the pull rope is pulled, the suspended pulley set moves downward so as to rotate an intermediate drive wheel. An endless flexible driving element is trained between the intermediate drive wheel and a driven wheel so as to rotate the driven wheel. A resistance setting unit is disposed on the frame assembly and can be adjusted so that a generator unit creates a predetermined amount of electric current, thereby activating a magnetic controller to change magnetic resistance to the rotation of the driven wheel.
