  • Patent number: 7115079
    Abstract: A multi-stage adjustable spring resistant belly massager comprises a belly massaging pad, a push-pull rod, a resistance adjusting mechanism and two handle grips. The belly massaging pad rests on the human belly, the push-pull rod is mounted in a barrel to perform the up and down movement, the resistance adjusting mechanism surrounds the push-pull rod and the handle grips are for the player to practice the push-pull exercise on the belly. The resistance adjusting mechanism is composed of a plurality of pulling guides, spring straps, a top decorative cover and a lock ring. The player operates the handle grips to carry out the up and down movement on the belly in one way and rotates the push-pull rod around the belly in other way to accomplish the weight reduction and fat removal in the belly.

  • Publication number: 20050209058
    Abstract: A stepper exerciser comprises a swinging base, a moveable base and a foot-stepping connecting rod, between the matching cases on the swinging base; there is a moveable base, to which a foot-stepping connecting rod is connected. A foot-stepping connecting rod mechanism, comprising an axle between the two side plates of the moveable base, a connecting rod extending out of the axle, a supporting base on each end of the connecting rod, a paddle on each supporting base, and the swinging base to allow simultaneous motion, and between the cases of the swinging base there is a recovery element, which can set the paddle in a non-swinging state when no action is exerted on the paddle and the swinging base returns to its non-swinging state; therefore, a lever mechanism is formed during the up-and-down of the paddles on the moveable base with the curved cases of the swinging base.

  • Patent number: 6773377
    Abstract: A hand exerciser includes a hollow sphere that has four openings and a cruciform member is supported in the sphere. Two handle disks and two massage disks are rotatably connected to four ends of the cruciform member and respectively engaged with the openings. A rod extends from a center of the cruciform member and a spring is mounted to the rod and a tube is rotatably mounted to the rod and biased by the spring. A weight is connected to a lateral rod extending from the tube. The eccentric force by the weight when the sphere is rotated applies a force to the hands holding the handle disks or the massage disks.
