Abstract: The present invention relates to a shock absorption structure for a treadmill having two handle frames, a support base, a frame portion and an adjustable supporting foot. A connecting arm has one end pivotably connected to the lower portion of each of both handle frames and the other end pivotably connected to the frame portion. A flexible shock absorption unit is pivotably interposed between an extension member of each handle frame and each connecting arm. Therefore, when the force is applied to the frame portion, both flexible shock absorption units provide proper cushioning effect. Moreover, the flexible shock absorption unit is constructed in such a way that the cushioning force can be freely adjustable so as to enhance the using comfort.

Abstract: The invention relates to a cushioning unit for an oval-tracked exercise device. A connecting element has one end pivotably attached to the elongated treadle and the other end pivotably attached to the handle bar. A lateral piece parallel to the connecting element is inwardly extended from the bottom end of the handle bars while a cushioning element is mounted on the lateral piece. When the handle bar is moved to the bottommost position, the connecting element presses against the cushioning element for achieving the expected cushioning effect, thereby preventing the operator's feet from shock caused by the reactive force of the elongated treadles.

Abstract: The invention relates to a treading exercise apparatus that includes a crank and a base. The crank is constructed as a first shaft in the middle thereof on which a bearing, a bushing and a resistance flywheel are received so that the crank rotates on a middle post of the base. Meanwhile, both sides of the first shaft are constructed as a correspondingly symmetric U-shaped treadle rod relative to the shaft which a treadle pad is rotatably received for treading movement in alternating succession. The outer side of each of the treadle rods is constructed as a second shaft. The second shafts and the first shaft are coaxially disposed along a horizontal axle line L. Moreover, the second shafts extend through side posts of the base respectively and are rotatably mounted thereon. Since the unbalanced force created by the treading movement on the crank is effectively supported, a stable treading movement can be achieved.

Abstract: The present invention relates to a control console automatically planning a personal exercise program in accordance with the physical condition measured through the whole exercise session. The control console is in connection with a heartbeat detector for any fitness equipment. A microprocessor is fitted within the control console and used to record the related change and the interactive relationship of the heartbeat value under exercise parameters of distance, speed, duration and slope during the whole exercise session whenever the operator uses the electric treadmill. Therefore, the current physical state of the certain operator can be exactly detected so as to automatically plan an optimal exercise program according to the personal physical state. In addition, this program will be saved and used for next time when the operator uses the electric treadmill again. Meanwhile, the current physical condition will be measured again so as to renew another optimal exercise program for the certain operator.

Abstract: A displacement detector of a platform for an exercise apparatus includes a rope movably tensioned by a rotating element between fixed points on the base and the upright support, respectively. When the platform is forced to move upwardly and downwardly, the rotating element undergoes an in-place rotation by the pulling force of the rope. Thereafter, a means for detecting the rotational displacement of the rotating element, which corresponds to the supporting force of the cushioning elements, is positioned beside the rotating element on the platform. Then, the detected value is transmitted to a microprocessor in the control console.

Abstract: The invention relates to an apparatus for diverting static electricity away from a treadmill. The apparatus includes a diverting apparatus, consisting of a conducting piece, a conductive strip and a connection bolt. The diverting apparatus is mounted on the surface of the platform without influencing the smooth rotation of the continuous belt for carrying off the static electricity produced by friction within a walking area of the treadmill by providing a direct grounding path through the connection of the other end of the conductive strip to the ground.

Abstract: The invention relates to a structure of rocker arms with optical sensing control for an exercise apparatus. The rocker arm of an exercise apparatus includes a handgrip. At least an optical sensor in accordance with the invention is positioned within a finger groove of the handgrip. The finger groove is so constructed that its form corresponds to the finger pad of the finger of an operator. Meanwhile, the finger groove is provided with an aperture in which the optical sensing element is hidden. The optical sensing element is connected to a console of the exercise apparatus through a conducting wire for setting different functions (exercise speed, slope or resistance) by means of effective detection signals. Therefore, the exercise apparatus is operable by means that a finger of both hands is slightly moved at fixed point during the exercise session.
