  • Patent number: 7743466
    Abstract: The present invention discloses a labor-saving pivotal shaft structure, comprising a fixed part and a movable part, wherein the movable part and the fixed part produce a frictional torque therebetween to provide the movable part with the functions of rotating, arresting, and positioning relative to the fixed part; and a torsion rod which is a rigid rod, whose one end is mounted onto the fixed part; such that the fixed part is connected to a main frame and the movable part as well as the other end of the torsion rod are respectively connected to a cover frame, and thus when the cover frame is being closed down, the fixed part is in a fixed condition and the torsion rod and the cover frame rotate together, leading to the torsion rod being in a twisted condition of storing energy; whereas when the cover frame is being opened up, the stored energy of the torsion rod is released to provide an auxiliary force.

  • Publication number: 20070214605
    Abstract: A sleeve joint type hinge includes a barrel, a pivot shaft, inserted into and rotatable relative to the barrel, and an arched resilient friction member, which has two hooked portions respectively extending from the two distal ends thereof and hooked on the periphery of the pivot shaft and a middle protruding portion kept spaced from a tangential peripheral plane of the pivot shaft and disposed in close contact with the inside wall of the barrel to produce a friction resistance and to hold the pivot shaft positively in positive after each rotary motion of the pivot shaft relative to the barrel by an external biasing force.

  • Patent number: 6511404
    Abstract: An exercise machine comprises a base, a resistance device, a control device, and a massaging device. The massaging device is formed of a pulse generator, a power source, and a plurality of massaging portions. The pulse generator and the power source are disposed in and controlled by the control device. The pulse generator is intended to generate a low frequency electric pulse, which is transferred to the massaging portions to promote the blood circulation in muscles, thereby resulting in the relief of muscular pain.
