Rotation by the second arm in direction opposite the first, however, engages the resistance mechanism to create a user-selected resistance to rotation.

  • Patent number: 7094182
    Abstract: Apparatus for exercising the forearm muscles responsible for movement of the hand at the wrist. The apparatus comprises two rigid rings adjoined by, and allowed to rotate about, the axis of a central, cylindrical variable resistance mechanism. The rigid rings each support a handgrip that is allowed to rotate about the inner circumference of each ring at variable resistance settings set with a peripheral resistance mechanism including an externally threaded terminal end of each handgrip, a knurled sleeve with internal threads at one end and external threads at the other. The knurled sleeve can be rotated about the axis of each handgrip, through internal threads of the inner ring, into the inner surface of the outer ring thereby creating a desired frictional resistance. The desired resistance can be preset and returned to through the incorporation of click-stops.

  • Patent number: 7087001
    Abstract: The present invention is directed to a portable personal training and exercise device with a cable and pulley mechanism which also is a mobile personal training and exercise device having an ergonomic plastic external housing that with the use of straps fits in the hand as well as against different parts of the body. The present invention has a cable and pulley mechanism inside a housing which has a pulley rotatably mounted on a shaft that spins in only one direction. The pulley spins in both directions so that it is spring biased for rewinding a cord onto the pulley. Next to the pulley is a brake wheel or brake bushing that is attached to the shaft. The brake wheel or brake bushing and a pulley spinning on a single shaft inserts into a sealed ball bearing on both ends. A spring is connected to the bottom of the pulley. In the center of the pulley is a combination ball bearing/one-way clutch that turns the shaft only in one direction. The shaft is attached to the brake wheel or brake bushing.

  • Patent number: 6773378
    Abstract: An exercise device with a true pivot point includes a first and a second arm joined at a joint assembly. The first arm is fixed in relation to the joint assembly and is also stabilized at an end opposite the joint assembly. The second arm rotates in a first, or in a second direction, about an axis of rotation which is defined by the joint assembly. A resistance mechanism is contained in the joint assembly which includes a one-way clutch interconnected to the second arm to allow the second arm to rotate freely in a second direction. Rotation by the second arm in a first direction, however, engages the resistance mechanism to create a resistance to the first rotation.

  • Patent number: 6770014
    Abstract: The present invention relates to a resistance type exercise device that uses frictional forces between members to provide resistance for a variety of different exercises. In operation, when a pull cord is withdrawn from the exercise device, a cord wheel converts the translational movement to rotational motion. A brake lever contacting a brake drum fixedly attached to the cord wheel provides a friction resistive force to the rotational motion. A recoil cord causes the recoil cord 900 to stretch and wrap around a bearing lug, placing the recoil cord in tension. The potential energy stored in the tensioned recoil cord is used to rewind the cord wheel and restore the pull cord back to its at rest position.

  • Patent number: 6736766
    Abstract: A rotational drive device that provides both variable levels of adjustable rotational resistance and also selective direction in which the resistance acts. The device has two mutually rotatable members each having a grasping handle. One member has a shaft serving as an axle for rotatably supporting the second member. A nut threads to the end of the shaft. When tightened, the nut imparts axially compressive forces urging the two rotatable members towards one another. The base rotatable member has a ramped member facing a corresponding opposed ramped member rotatably supported on the shaft. When the ramped members are rotated relative to one another, overall axial length of the base member is adjusted. This adjustment selectively modifies resistance to rotation of the rotatable members. A clutch device selectively transmits resistance forces when one rotatable member is rotated relative to the other in a first direction, in a second direction, and in both directions.
