ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates generally to baseball accessories for aiding a batter in properly gripping and controlling a baseball or softball bat and for protecting a batter's hand from bruising or injury, including bone bruise injuries. More particularly, this invention relates to a pad worn over the thumb and between the thumb and forefinger for aiding a batter in gripping a bat.
In order for a batter to properly grasp a baseball bat, the batter should place the bat handle diagonally across an open hand, then grasp the bat primarily with the fingers, and not with the palm of the hand. The index finger and the middle finger are particularly important in grasping a bat. Grasping the bat primarily with the fingers instead of the palm not only aids the batter in controlling the bat, but it helps the batter more securely grasp the bat. A grip using primarily the fingers thus increases leverage, bat control and placement, and bat speed, thus allowing a more powerful and accurate batting stroke. If a bat is grasped deep in the palm of the hand, and if the bat rests back in the area between the thumb and index finger, the batter is not likely to have proper control of the bat, the bat may wiggle or slide between the fingers and into the palm area between the thumb and index finger, and the batter's leverage, bat control and placement, and bat speed and power may be reduced.
A strong shock or sting is often sent through a bat to a batter's hand when the batter hits a ball off the thin portion of the bat or off the end of the bat. This shock can bruise the batter's hand, particularly the area of the palm (typically near or at the base of the thumb) and index finger (typically near or at the base of the index finger). Many batters develop a bruise near or at the joint of the thumb and the hand or near or at the joint of the index finger and the hand. These bruises can interfere with a batter's game, can be painful, and can linger for an extended or permanent period of time due to periodically recurring shocks to the same area of the hand.
Many devices are known in the art to reduce the effect of the shock from hitting a baseball off the wrong spot on a bat. Some of these devices include batting gloves, which dull shocks from hitting a baseball, and pads to cushion the area between the thumb and index finger. One such pad is disclosed in U.S. Pat. No. 4,461,043. This patent discloses a cushion with a ring to fit over the thumb and an elongated portion to cushion the palm between the thumb and forefinger.
FIGS. 1
,
2
,
5
, and
7
of the present application illustrate a pad similar to that disclosed in U.S. Pat. No. 4,461,043.
As can best be seen in
FIGS. 1 and 2
, the pad of U.S. Pat. No. 4,461,043 consists of an elongated member
10
having a ring portion
12
containing an opening
14
to fit over a batter's thumb and a flap portion
16
extending from the ring portion
12
to cushion the area between the batter's thumb and index finger.
FIG. 5
illustrates the ring portion
12
of the member
10
fitting over the batter's thumb
30
. When this pad is in use, the flap portion
16
of the pad extends to the index finger
34
of the batter's hand. As shown in
FIG. 1
, the lower surface
18
of the member
10
is relatively flat. The upper surface
20
of the member
10
on the flap portion
16
is curved. When the batter squeezes the bat
40
, as shown in
FIG. 7
, the lower surface
18
of the member
10
contacts the bat
40
and pushes the bat
40
away from the palm area
32
of the batter's hand and toward the batter's fingers, referred to collectively as
36
.
Although the batting pad of U.S. Pat. No. 4,461,043 serves its purpose in general, it has a number of disadvantages.
FIG. 5
of the present application illustrates this batting pad in the batter's hand without the bat
40
tightly gripped and
FIG. 7
illustrates this batting pad with the batter gripping the bat
40
. Because of the length of the member
10
, particularly from the ring portion
12
to the tip
22
of the flap portion
16
, the typical batter must compress and bend the flap portion
16
to tightly grip the bat
40
. As can be seen in
FIG. 7
, the member
10
is not thick enough to push the bat
40
far enough toward the fingers
36
to allow the batter to easily grip the bat
40
with the fingers
36
instead of with the palm of the hand.
Another disadvantage of the batting pad of U.S. Pat. No. 4,461,043 is that it forces a batter to grip the bat
40
and batting pad somewhat tightly to securely grip the bat
40
. As
FIG. 7
illustrates, the batting pad must be compressed in length to allow the fingers
36
to wrap around the bat
40
to secure the batter's grip.
FIG. 7
shows the movement of the index finger
34
and entire hand to adequately secure the bat
40
when this batting pad is used.
A need exists for a batting pad to cushion the area between the batter's thumb
30
and index finger
34
that optimizes the batter's grip of a bat, reduces the slop in a batter's grip so that the bat and pad fit snugly in the batter's hand, enables the batter to easily grip the bat with the fingers instead of with the palm of the hand, and that is properly shaped to allow the batter to easily grip the bat in a more technically favorable position with only slight movements of the batter's fingers.
BRIEF SUMMARY OF THE INVENTION
A batting pad comprising a body made from a cushioning material and having a ring portion adapted to fit over a batter's thumb and an appendage to cushion the palm area between a batter's thumb and index finger. The appendage has a thickness T at its thickest point located between the first end and the distant end, and the thickness T of the appendage is selected to optimize an angle of a bat in the batter's hand relative to a line parallel to the batter's forearm, the angle being determined by the thickness T of the appendage displacing the bat toward the tip of the batter's index finger and causing the bat to contact the palm of the batter's hand near the batter's little finger. In another embodiment, the length of the appendage may be selected to aid in displacing the bat toward the tip of the batter's index finger and causing the bottom of the bat near the knob of the bat to contact the palm of the batter's hand near the batter's little finger.
Another embodiment of the invention is a batting pad comprising a body made from a cushioning material and having a ring portion adapted to fit over a batter's thumb and an appendage to cushion the palm area between a batter's thumb and index finger. In this embodiment, the appendage has a thickness T at its thickest point located between the first end and the distant end, and the thickness T of the appendage is selected to optimize an angle of the bat in the batter's hand relative to a line parallel to the batter's forearm, the angle being determined by the thickness T of the appendage displacing the bat toward the tip of the batter's index finger and causing the bat to contact the palm of the batter's hand near the batter's little finger, and such that the thickest point of the appendage contacts the palm area of the batter's hand between the proximal joint of the batter's thumb and the proximal joint of the batter's index finger. The appendage also has a length N between a first end adjacent the interior side of the ring portion and a distant end of the appendage, wherein the length N is selected such that when the batter grips the bat the appendage is substantially free of longitudinal compression and the distant end of the appendage contacts the palm area near the proximal joint of the batter's index finger.
Yet another embodiment of the invention is a device to aid a batter in gripping a bat comprising. This embodiment comprises a glove and a body made from a cushioning material and having a ring portion adapted to fit ov
