Grip strengthener with therapy ball

Grip strengthener with therapy ball description/claims

1. Field of Invention

The present invention relates to a grip strengthener, and more particularly to a grip strengthener with therapy ball.

2. Description of the Related Art

Conventional grip strengtheners and therapy balls use resilient or elastic objects such as springs or rubber and are squeezed or rolled to exercise a person's hand for strengthening the person's wrist, fingers and arm to build gripping strength for sports or recover from injury.

A conventional therapy ball is repeatedly gripped tightly and released by a person to exercise their fingers. With reference to FIG. 6, a conventional grip strengthener (40) is used to strengthen a person's wrist, is palm-sized, flat and has four side surfaces, a top surface and a finger slit (41). Each side surface is concave to correspond to a person's fingers and thumb. The finger slit (41) is defined in the top surface of the conventional grip strengthener (40) near one of the side surfaces. So the person can insert several fingers into the finger slit (41) and place other fingers on a side surface of the conventional grip strengthener (40) opposite to the thumb. Then the person can curl the fingers in the finger slit (41) to grip the conventional grip strengthener (40) and exercise the person's wrist. However, both the conventional grip strengthener and therapy ball focus on one area. If the person wants to exercise both their wrist and fingers, the person must buy both the conventional grip ball and grip strengthener (40) and perform two sets of exercises.

To overcome the shortcomings, the present invention provides a grip strengthener to mitigate or obviate the aforementioned problems.

The primary objective of the present invention is to provide a grip strengthener with therapy ball that can exercise a person's wrist and fingers.

A grip strengthener with therapy ball in accordance with the present invention comprises a resilient pad and ball. The pad is flat and has at least one side surface, a top surface, a bottom surface, a ball mount and a finger slit. The ball mount is defined through the pad and has an inner edge. The finger slit is defined in the top surface of the pad between the ball mount and one of the at least one side surface. The ball is mounted detachably in the ball mount of the pad and has an outer surface, a mounting groove, a top side and a bottom side. The mounting groove is defined around the outer surface of the ball and engages the inner edge of the ball mount of the pad. The top side and the bottom side of the ball protrude respectively from the top surface and the bottom surface of the pad. The grip strengthener with therapy ball can be used together to exercise a person's wrist and fingers or separated to focus an exercise on the fingers or the wrist.

Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
