  • Patent number: 10004944
    Abstract: A mandatory hooking/locking device for an elevating footboard of a pull-up exercise machine includes a touch-pressing rod disposed at stepping positions with respect to an exerciser's two soles separately and acted by a rotary plate and a torsion spring to achieve a lifting effect to freely penetrate and slightly elevate from an end surface of the elevating footboard, and a hooking portion disposed at the bottom end of the rotary plate being provided for hooking to a corresponsive latch column of an inwardly extending section in the floor affixing front stand, so that the hooking portion of the rotary plate can be separated from the latch column only if the two touch-pressing rods are stepped and pressed down simultaneously, so that the elevating footboard performs the expected ascending and descending motions to ensure the safety of use.

  • Patent number: 9855457
    Abstract: A pull-up fitness exercise machine includes a base, a cantilever, a cantilever aligning unit, a pulling and latching unit, an assisted pushing unit, a limit assembly and a support plate. At a low static position, the support plate is acted by the limit assembly and fixed to a bottom position of the base, such that only after a specific gravitational force is exerted onto the support plate, and the cantilever is pulled downward, the support plate is released from a locked status. In addition, a central column at the bottom of the base has an inverted hook member operating together with a circular ring installed at a corresponding position of the support plate to form a secondary safety device to prevent the support plate to have any unexpected lifting movement and ensure the safety of use.

  • Publication number: 20140213416
    Abstract: An electronic control dashboard capable of displaying fitness age, comprising an operating interface disposed at an end surface of the electronic control dashboard. A microprocessor and related circuit connecting terminals are installed in the electronic control dashboard for electrically conducting a circuit to control the operation of a fitness equipment. The operating interface further comprises a fitness age display area for displaying a message transmitted from a heartbeat detector, such that after the specific user completes an exercise session, the microprocessor immediately converts the user's recovery heart rate into a fitness age and displays the fitness age at the fitness age display area. Moreover, a weight difference of the specific user or an effective exercise heart rate measured during the whole exercise process can be used as parameters for the conversion of the fitness age.

  • Patent number: 8721504
    Abstract: A cushioning mechanism of a treadmill is interposed with an auxiliary plate between a base frame and the running board. The cushioning mechanism includes two hanging support pieces, two hanging swing pieces, and a flexible elastic element. When the running board is subject to a downward force and sinks, the flexible elastic element will be pulled and expanded externally. When the external force is eliminated, the running board will be returned back to its original position by the self-restoring ability of the flexible elastic element. In this way, an expected and optimal cushioning effect is achieved.

  • Patent number: 8668628
    Abstract: An electric treadmill with a folding mechanism by use of two swivel pieces includes a handrail frame mounted at both sides of the front end of the base frame. A base frame swivel piece is pivotally positioned at both sides near the front part of the bottom of the base frame, respectively. A handrail frame swivel piece is pivotally disposed near the bottom of the handrail frames, respectively. A pull rod is pivotally interposed between the swivel pieces. A movable support with ground-touching rollers is pivotally coupled to a cross shaft of the base frame swivel pieces. Moreover, the movable support is constantly biased by a telescopic supporting element. In this way, an action bar of the telescopic supporting element pushes the movable support forward when the base frame is folded upwards. Meanwhile, the ground-touching rollers are constantly in contact with the ground. Accordingly, a stable folded-up position is achieved.
