  • Patent number: 7901334
    Abstract: The present invention relates to an exercise apparatus with an adjustable resistance assembly. The adjustable resistance assembly has a screw portion. An user can rotate an operating portion which is connected to one end of the screw portion to move the screw portion to drive a pushing portion toward a rotating member which is pivotally connected on the exercise apparatus. Simultaneously, the pushing portion drives an elastic member to cause deformation and make a friction surface of a resistance member which is connected on the elastic member gradually press the rotating member therefore increases friction resistance. When the user rotates the operating portion reversely, the screw portion is moved outward the rotating member and the elastic member recovered from the deformation thereby decreases the friction resistance relative to the rotating member.

  • Publication number: 20060225539
    Abstract: An adjustable wrench includes two walls disposed on an upper portion of a handle body to define a guiding slot therebetween. A driving shaft is rotatably mounted in the guiding slot. Two movable jaws have coupling portions which are coupled respectively to two connecting ends of the driving shaft by force transmitting mechanisms such that a rotational force of the driving shaft about a rotating axis is transmitted to drive the coupling portions to move along the rotating axis toward or away from each other, and two jaw portions which extend outwardly of the guiding slot for gripping a torqued object. Two operating members are disposed to flank the connecting ends and are operable to rotate the driving shaft such that the distance between the jaw portions can be adjusted to permit quick gripping and releasing of the torqued object.
