ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a ball for exercising a person's hands and relieving stress.
2. Prior Art
Various rubber balls, tennis balls, and the like have been used by persons to strengthen the hands and forearms by exercises that involve alternately squeezing the ball and relieving hand pressure on it.
BRIEF SUMMARY OF THE INVENTION
The present invention is directed to a novel exercise ball which may be used for the purposes just mentioned but is primarily intended for improving the user's manual dexterity and the tactile sensitivity of his fingers, particularly the fingertips. The ball of this invention is spheroidal and has a soft surface with a feel to a person's fingers closely simulating the feel of human skin. The ball as a whole is manually deformable and resilient, with a viscosity closely comparable to that of a woman's breast. The ball presents an outwardly protruding, rounded nipple surrounded by a ring that presents small surface irregularities. The nipple and the ring on the surface of the present ball closely simulate in shape and feel the nipple and areola of a woman's breast.
A principal object of this invention is to provide a novel exercise ball that may be used by a person to strengthen his hands, to improve his manual dexterity, to improve the tactile sensitivity of his fingers, and to relieve stress.
Further objects of this invention will be apparent from the following detailed description of a presently preferred embodiment thereof, shown in the accompanying drawings.
