  • Patent number: 7824312
    Abstract: An exercising handgrip includes a base, a first handle mounted on the base, a second handle movably mounted on the first handle and disposed between the base and the first handle, a threaded tube movably mounted on the base, a tensile spring mounted in the threaded tube and biased between the threaded tube and the second handle, and a threaded adjusting knob rotatably mounted on the base and screwed onto the threaded tube. The base has two limit ribs. The threaded tube has two limit slots each slidable on the respective limit rib of the base. Thus, the adjusting knob is rotated in the base to move the threaded tube relative to the second handle and to compress or extend the tensile spring so as to adjust the tension of the tensile spring.

  • Patent number: 7824311
    Abstract: An exercising handgrip includes a first handle, a second handle pivotally connected with the first handle, a damping spring biased between the first handle and the second handle, a threaded adjusting module movably mounted on the second handle and pressing the damping spring, and a threaded adjusting knob rotatably mounted on the second handle and screwed onto the threaded adjusting module to move the threaded adjusting module relative to the damping spring by rotation of the adjusting knob. Thus, the adjusting knob is rotated on the second handle to drive the threaded adjusting module to move forward or backward relative to the second handle so as to change the distance between the first handle and the second handle and to compress or extend the damping spring, thereby adjusting the damping force of the damping spring.
