Wrist exercise device

Abstract

A device that exercises a wrist of a user by converting a pivotal motion into a linear motion. The device includes a base, a pair of pivoting assemblies, a pair of resistance assemblies, and a grip. The base is placed on a support surface. The pair of pivoting assemblies extend upwardly from the base and are spaced apart from each other to have the wrist of the user placed therebetween. The pair of resistance assemblies depend from the pair of pivoting assemblies, respectively, to the base. The grip extends from one pivoting assembly to the other pivoting assembly and is gripped by a hand of the user, and when pivoted downwardly by the hand of the user, the pair of pivoting assemblies pivot downwardly which in turn causes the pair of resistance assemblies to extend linearly upwardly and provide a resistance, and in doing so, converts the pivotal motion into the linear motion.

A mass of tiny glass spheres having the consistency and appearance of a fine powder is enclosed in a resilient inner bladder surrounded by a resilient outer bladder, and a thin layer of powder is disposed between the exterior surface of the inner bladder and interior surface of the outer bladder to prevent theme from sticking together, to reduce friction therebetween, and to allow relative sliding movement between the surfaces. The tiny spheres provide low resistance to relative particle movement by rolling on each other upon an increase or decrease in pressure applied to the device. When placed on a flat surface beneath the wrist of a user, the device deforms slightly and conforms to the underside of the user's wrist to form a comfortable cradle-like support as the downward pressure of the wrist increases or decreases. As the wrist is moved relative to the flat surface, the device smoothly rolls between the wrist and the flat surface to provide a smooth massaging effect on the wrist while maintaining wrist support. The resilient device can be squeezed in the palm of the hand to exercise the muscles of the hand, fingers, wrist, and forearm.
