  • Patent number: 9421415
    Abstract: A rope pulling exercise apparatus includes an exercise base, a rope base, a pivot base, a pivot-base pulley and a rope. The rope base along an exercise direction has a first end and a second end, and the first end is connected to the exercise base. The pivot base is pivotally joined to the second end of the rope base. A swing direction of the pivot base is relative to the exercise direction. The pivot-base pulley is pivotally connected at the pivot base. The rope has one end connected to the rope base and the other end for pulling along the exercise direction, and the rope is wound around the pivot-base pulley.

  • Patent number: 9278244
    Abstract: A fitness apparatus includes a first frame, a second frame, a nose part, a linear elastic element, and a lever. The second frame and the nose part are coaxially and pivotally connected to the first frame. The nose part is swingly connected to the second frame. The lever drives the linear elastic element. The linear elastic element is extendedly bounced and blocked on the first frame. When the second frame pivotally swings against the first frame, the movable range of the linear elastic element will be constrained by the lever because of its high stiffness. In addition, the linear elastic element can stably bounce instead of hitting the inner wall of the first frame. Therefore, the fitness apparatus using the lever can prevent the linear elastic element from sounds of hitting and attrition, so as to achieve the purpose of low noise and increasing the life time of components.

  • Patent number: 9238157
    Abstract: A fitness apparatus includes a first frame, a second frame, a nose part, a linear elastic element, and a cable. The second frame is pivotally connected to the first frame. The nose part and the second frame are coaxially pivotally connected to the first frame. The linear elastic element has a first end and a second end. The first end is connected to the first frame. The cable has a connecting end and a force-applying end. The connecting end is connected to the second end. The cable is pressed against the nose part, and the force-applying end of the cable drives the second frame. When the second frame pivotally swings against the first frame, the second frame pulls the cable and changes the length of the cable pressed against the nose part, whereby the linear elastic element may be stretched or shortened by the cable.
