Grip strengthener with therapy ball
Abstract
A grip strengthener with therapy ball includes 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 in the pad. The top side and the

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of Invention
[0002] The present invention relates to a grip strengthener, and
more particularly to a grip strengthener with therapy ball.
[0003] 2. Description of the Related Art
[0004] 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.
[0005] 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.
[0006] To overcome the shortcomings, the present invention provides
a grip strengthener to mitigate or obviate the aforementioned
problems.
SUMMARY OF THE INVENTION
[0007] 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.
[0008] 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.
[0009] 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.

DETAILED DESCRIPTION OF THE INVENTION
[0016] With reference to FIG. 1, a grip strengthener with therapy
ball in accordance with the present invention comprises a pad (10)
and a ball (20).
[0017] The pad (10) may be rubber or silicone, is flat, resilient
and has at least one side surface, a top surface, a bottom surface,
a ball mount (13) and a finger slit (14). The top surface is larger
than each one of the at least one side surface and corresponds to
the bottom surface. The ball mount (13) is defined through the pad
(10), has an inner edge and may be circular. The inner edge of the
ball mount (13) may be convex. The finger slit (14) is defined in
the top surface of the pad (10) between the ball mount (13) and one
of the at least one side surface for inserting of a person's
fingers. Preferably, the pad (10) has four side surfaces and each
side surface is concave for gripping of the person's fingers.
[0018] With further reference to FIG. 2, the ball (20) is
resilient, may be rubber or silicone, is mounted detachably in the
ball mount (13) in the pad (10) and has an outer surface, a
mounting groove (21), a top side and a bottom side. The mounting
groove (21) is defined around the outer surface of the ball (20)
and engages the inner edge of the ball mount (13) of the pad (10).
The top side and the bottom side of the ball (20) protrude
respectively from the top surface and the bottom surface of the pad
(10).
[0019] With further reference to FIG. 3, when the person wants to
exercise their wrist and fingers at the same time, the person
places his/her thumb on one of the at least one side surface of the
pad (10) and inserts his/her fingers into the finger slit (14) of
the pad (10). Then the grip strengthener with therapy ball is
repeatedly gripped tightly and released to exercise the person's
fingers. People with different palm sizes can place their thumb at
different positions of the pad (10) for a comfortable grip.
[0020] With further reference to FIG. 4, when the person only wants
to exercise their wrist, the person can put the grip strengthener
with therapy ball on a solid surface such as a desk, table or floor
and push his/her palm against the ball (20) in different
directions.
[0021] With further reference to FIG. 5, when the person only wants
to exercise their fingers, the person can remove the ball (20) from
the pad (10) and alternately grips and releases the ball (20) with
his/her fingers. The ball (20) can be materials of different
resiliences. When the person has a higher finger strength after
practicing, the person can exercise his/her fingers with a ball
(20) of less resilience to keep improving the finger strength. The
ball (20) can also be switched for people of different finger
strengths, such as adults and children.
[0022] The grip strengthener with therapy ball can exercise a
person's wrist and fingers at the same time, so the person needs
not to buy both a conventional therapy ball and a grip
strengthener. Using the grip strengthener with therapy ball is also
convenient because the person exercises different parts of the hand
at the same time.
[0023] Even though numerous characteristics and advantages of the
present invention have been set forth in the foregoing description,
together with details of the structure and function of the
invention, the disclosure is illustrative only. Changes may be made
in detail, especially in matters of shape, size and arrangement of
parts within the principles of the invention to the full extent
indicated by the broad general meaning of the terms in which the
appended claims are expressed.
