Balance-enhancing and vibration-reducing device for wrist exerciser |
摘要 |
A balance-enhancing and vibration-reducing device is incorporated in a wrist exerciser to enhance force balance and reduce vibration caused in the operation of the wrist exerciser. The device includes a ring mounted in a casing of the wrist exerciser and defining diametrically opposite holes that rotatably receive axles of a rotor of the wrist exerciser. A coupler is mounted to an inner circumference of the ring in position corresponding to at least one of the holes. The coupler includes a tube extending in a radial direction of the ring. The tube forms a central bore to rotatably receive the corresponding axle. A plurality of resilient pawls is formed at a free end of the tube and distributed along a circumference of the free end. A balance-enhancing and vibration-reducing element has a central bore fit over the tube of the coupler by elastically deforming the pawls. The pawls so deformed resume their original position by the resiliency thereof to retain the balance-enhancing and vibration-reducing element on the tube. The balance-enhancing and vibration-reducing element effects weight balance and absorption of mechanical vibration force during the rotation of the rotor thereby maintaining stable and noiseless operation of the wrist exerciser.
