  • Publication number: 20030134726
    Abstract: A multi-directional swivel body builder constitutes a bent shank, two sections of joint tube having a ring groove and a lock hole at its far end. The joint tube houses a retaining spring having a turnover leaf and a lock post fitted into the lock hole of the joint tube. The joint tube is inserted into the sleeve tube of the handle. The sleeve tube provides a plurality of adjusting holes. When the joint tube slides in place in the sleeve tube, the catch lug on the inner wall of the sleeve tube will enter the ring groove of the joint tube and press the retaining spring so to allow the handle to move freely along the ring groove for proper angular adjustment. The far end of the handle links with an end wheel. When waving the end wheels with two hands, the bent shank will rotate in cycle.

  • Publication number: 20030134716
    Abstract: A hand operable exercising machine includes a handle, an inertial rotation body rotatably mounted on the handle, and an electronic counter secured on the handle. The handle includes a pivot rod, two detachable connecting seats secured on the two ends of the pivot rod, and two handgrips pivotally mounted on the two detachable connecting seats respectively. Thus, the user's hands may hold the two handgrips to rock and rotate the inertial rotation body, so that the inertial rotation body may be rotated by the inertial action of the inertial weight, thereby exercising the muscles of the user's hands.

  • Publication number: 20030103352
    Abstract: A hand-waving illuminant circlet employed as a sports appliance, mainly comprising a cylindrical collar, a rotary hub and at least a loaded illuminant element. The cylindrical collar fastens a handle at its inner rim and holds a ring gear at its outer perimeter. The rotary hub comprises a pair of symmetric disks for eccentric rotation. The inner perimeter of the disks forms a clamp rail for the ring gear to rotate along. The loaded illuminant element comprises two illuminant wheels and a spur gear going between. The spur gear meshes on the ring gear. When the player waves the circlet, the eccentric rotation generated in the rotary hub produces a centrifugal force causing the illuminant element to circumnavigate along the ring gear; besides, the illuminant element produces a fantastic glare providing great fun in practice.

  • Publication number: 20030092546
    Abstract: A powerful waist twister comprises mainly a handle bar, a post column and a twisting mechanism. The twisting mechanism is housed in a base casing with a top lid, in which two rotors, two spring elements, two rotor covers, a connecting rod, and a swing shaft are installed in the manner that each of two rotor seats, mounted along the sidewall of the base casing, receives one of two rotors which are further riveted on the base casing. The connecting rod links to both rotors with the central part pivoted to the swing shaft. The terminal end of the swing shaft is hooked with two spring elements which exert the reversible force to return the swing shaft back during the swing movement. The rotor seats produce a movement in the exactly opposite direction toward the movement of the handle bar, that means while the upper body moves in the right direction, the lower body will twist in the reverse direction to render the waist twisting and swinging movement.

  • Patent number: 6527675
    Abstract: An illuminating hand-shaking exerciser with a triple rotating axle mainly comprises a main shell having internal rotary collars connected to shells by an axle. When two semi-spherical covers of two sets of matching shells are closed against each other, a space is provided for internal rotary collars. One shell holds several lighting coils. The internal rotary collars are placed in the order of large, medium and small collars. The small collar has a groove at inner edge to lock an inertial magnetic weight inside. When the user grasps the shell and shakes it around, the large, medium and small collars will rotate three-dimensionally. Further, due to inertial rotation by the inertial magnetic weight inside the small collar, the entire exerciser will shake vigorously. Meanwhile, the lighting coils will illuminate due to inertial rotation of the magnet. Thus, the exerciser provides hand exercise with entertaining effect of illumination.

  • Patent number: 6514179
    Abstract: A rolling ball hand-shaking exerciser comprises at least one main casing and one ball coated externally with soft material which rolls internally in the casing. The casing constitutes two identical semispherical shells interlocked integrally and extend outward to form tow handles. At the central beak of the shell a string of small pellets encircles one layer after layer with slightly projected head. When the player holds the handles and turns it around an orbit, the ball rolls in an inertia revolution manner with the limited space inside of the casing, it creates a vibration and damper action to achieve the hand exercise, and the pellets work as the massaging material as well.

  • Patent number: 6461276
    Abstract: A hand-shaking exerciser outfitted with an internal rotor comprises a hollow casing and a rotor shaft. The hollow casing consists of two identical semispherical shells interlocked integrally and extending outward to form two handles. At the far top of the shell, many small hard pellets are installed. The internal inertia rotor shaft is composed of two crown plates, an inertia weight and a wheel plate, one of which has an oval head at one side and one sleeve at other to receive the inertia weight. Two crown plates will hold and lock the inertia weight and wheel plate firmly to constitute an integral rotor shaft. When the player holds the handles and shakes the exerciser, the rotor shaft will make a free inertia rolling within the casing. The vigorous rolling of the rotor shaft will produce powerful vibration force acting as a massaging force to achieve the practical purpose.

  • Patent number: 6364816
    Abstract: An arm-building device comprises a frame having a coupling portion. Two engagement members are rotatably mounted on the frame such that they are meshed with each other. The engagement members are provided with a connection portion and a pivoting portion. Two operation rods are connected with the connection portions of the engagement members. Two traction members are pivotally fastened with the pivoting portions of the engagement members such that the traction members are pivoted at one end thereof by a bolt. A resilient member is connected at one end with the coupling portion of the frame and is fixed at other end by the bolt. The two operation rods are actuated by hands of an exerciser, so as to actuate the engagement members to rotate to cause the two traction members to displace upward to stretch the resilient member. A recovery spring force is thus brought about by the stretched resilient member to work against both arms of the exerciser.
