Abstract
A swing practicing device trains a hitter, such as a baseball batter, to improve the accuracy and power of his swing. A target is coupled to the terminal end of a target support, the target accepting swing impacts without separating from the target support. The target support extends from a base having a rounded bottom surface, the curves of the rounded surface in rotational engagement with the ground. Swing impacts at the target cause the apparatus to rotate from an upright position to a more horizontal position and then return to the upright position to accept repeated swing impacts. The device can include an inflatable air bladder within the target and target support, and can include an adjustable weight for its base. The device can also include an adjusting mechanism to adjust the vertical height of the target.
Description
TECHNICAL FIELD OF THE INVENTION
This invention relates in general to a swing practicing apparatus, and more particularly to a baseball swing practicing apparatus for improving swing power and precision.
BACKGROUND OF THE INVENTION
Hitting a baseball well requires precise timing and a powerful swing. To improve their baseball swing, baseball players must practice their swing mechanics repeatedly. Although players can practice swing mechanics by actually playing the game of baseball, other practicing techniques are necessary because of the very nature of the game. In baseball, a pitcher tries to throw the ball into a strike zone in an unpredictable way to prevent the batter from hitting the pitch. Thus, hitting each actual pitch can require a slightly different swing and does not necessarily reinforce desired swing mechanics. Further, the process of playing a baseball game is time-consuming and can require a large playing area. Thus, the game of baseball itself is not conducive to the repetitious practicing needed to optimize swing mechanics.
A variety of methods and devices have evolved over the years to support practicing of a baseball swing in an efficient yet expeditious manners. For instance, players can practice their swing in a batting cage by receiving nearly identical pitches from an automatic pitching machine. Alternatively, players can practice a baseball swing by hitting a baseball from a tee. Both of these practicing techniques help to improve a player's hand-eye coordination, but hitting an actual baseball does not significantly improve the power of a player's swing without extensive repetition. Further, hitting an actual ball can reduce the number of repetitions which a player can achieve due to the time needed to chase down and recover the hit balls. Also, hitting an actual ball for practice generally needs a large playing area or a restraint to catch the balls after they are hit. Thus, practice involving the hitting of an actual ball generally is restricted to fair weather.
Some methods and devices allow practice with fixed targets. One technique employed by coaches to improve the power of a swing is to have a player repeatedly hit a suspended tire. Hitting a suspended tire improves swing power by absorbing the energy of a swing but does nothing to improve the player's hand-eye coordination. Mechanical targets, such as that disclosed in U.S. Pat. No. 5,035,424 issued to Liao, have been devised to offer a fixed target to a hitter, but existing devices are complicated and have moving parts which can break off to destroy the device and cause injury to the hitter or a nearby observer.
SUMMARY OF THE INVENTION
Therefore, a need has arisen for a swing practicing apparatus which will absorb swing energy to provide improved swing power while providing a target small enough to practice hand-eye coordination for improved swing precision.
In accordance with the present invention, a swing practicing apparatus is provided that substantially reduces disadvantages and problems associated with previously developed apparatus for swing improvement. A target support extends from a base, the target support having a terminal end. The base has a rounded bottom surface for rotational engagement with the ground. A target is coupled to the terminal end of the target support. A hitter can swing at the target to practice and improve the hitter's swing power and precision. The target accepts the swing impact without separating from the target support. The impact forces the base to rotate along the rounded surface from an initial upright position to a more horizontal position. The weight distribution of the apparatus then biases the apparatus to rotate along the rounded surface back to the upright position.
More specifically, the target and target support are comprised of a durable, energy-absorbing material for absorbing swing impacts, such as nylon reinforced rubber similar to the material found in automotive tires. The target support and target can include an inflatable bladder in their interior, the inflatable bladder providing improved support for accepting swing impacts. The base can incorporate a weight sufficiently heavy to bias the base to an upright position. The weight can comprise a replaceable substance, such as sand or lead pellets, which can be stored in a cavity in the base.
In one embodiment, an adjusting mechanism can be incorporated in the base and target support for adjusting the vertical height of the target when the apparatus is in an upright position. The adjusting mechanism can comprise a first thread incorporated with the target support and a second thread associated with the base. The threads cooperate to adjust the vertical height of the target by rotating the target support relative to the base. The first thread can be formed in the interior of the base, with the target support having the second thread incorporated in its exterior surface so that the target support screws into the base. The target support and base can be locked into a fixed position by filling the air bladder.
The present invention provides important technical advantages for practicing swing mechanics to improve a swing. For instance, the present invention provides an automatically repeating target which can allow a hitter to repeatedly practice his swing without resetting the target after each swing.
Another important technical advantage is the simple and virtually indestructible construction of the present invention which allows the absorption of repeated swings without breaking or falling apart.
Another important technical advantage of the present invention is its construction with minimal or no moving parts, and especially metal parts, which can break loose upon swing impact to cause injury to the hitter or observers nearby.
Another important technical advantage is that the present invention can be used indoors in limited space to allow batting practice during inclement weather.
Another important technical advantage of the present invention is that it allows a hitter to practice and improve hand-eye coordination and swing power simultaneously.
BRIEF DESCRIPTION OF THE DRAWINGS
A more complete understanding of the present invention and advantages thereof may be acquired by referring to the following description taken in conjunction with the accompanying drawings in which like reference numbers indicate like features and wherein:
FIG. 1
depicts a side view of a hitter swinging at one embodiment of the present invention; and
FIG. 2
depicts a cutaway view of an apparatus according to the present invention which incorporates an adjusting mechanism for adjusting the vertical height of the target.
DETAILED DESCRIPTION OF THE INVENTION
Preferred embodiments of the present invention are illustrated in the figures, like numerals being used to refer to like and corresponding parts of the various drawings.
The swing practicing device according to the present invention provides an automatically repeating target for batting practice which can improve both the power of the batter's swing and the batter's hand-eye coordination. The automatically repeating target is accomplished with a rounded and weighted base that is in rotational engagement with the ground. When the base is knocked over by the impact of a swing, it automatically rights itself and stands ready for another swing.
Referring now to
FIG. 1
, one embodiment of an apparatus
10
according to the present invention is depicted being used by a batter
12
swinging a baseball bat
14
. Batter
12
directs the swing so that bat
14
impacts target
16
, which is formed in the shape of a baseball. Target
16
absorbs the impact of the swing and translates the energy of the impact through a target support
18
to a base
20
. Target
16
, target support
18
and base
20
rotate from the initial upright position existing at the time of impact towards a more horizontal position, and then return to the upright position to allow batter
12
to repeat his swing at target
16
.
Base
20
has a rounded bottom
22
that is in resting engagement with the ground
24
. In one embodiment, base
20
has a flat bottom
26
to minimize movement of apparatus
10
prior to receiving a swing impact. Rounded bottom
22
has curves extending from the flat bottom
26
of base
20
to the top of base
20
. Base
20
can include an opening
28
to allow for the addition of weight to base
20
. For instance, sand or lead pellets can be added to a cavity formed within base
20
through opening
28
to adjust the effect of a swing impact on the movement of target
16
towards a horizontal position. The addition of weight to base
20
allows for absorption of a more powerful swing impact with less movement towards a horizontal position, and provides a greater bias to rotate target
16
to an upright position.
Target
16
, target support
18
, and base
20
can be constructed of 0.125 inch thick nylon reinforced rubber similar to the material used to construct automotive tires. Alternative materials can be used if the materials are sufficiently tough enough to absorb repeated swing impacts without allowing the target to separate from the target support. Target
16
, target support
18
and base
20
can be formed as one piece, or as plural pieces coupled together by any conventional means. Preferably, the construction will avoid the use of metal parts which can break off and cause injury, although a metal weight can be incorporated within base
20
to increase the bias of base
20
to an upright position.
Referring now to
FIG. 2
, a swing practicing device according to the present invention is depicted in cutaway view. A cavity
21
is depicted in base
20
for accepting additional weight. An inflatable bladder
30
is located in the interior of target support
18
. Bladder
30
can be formed by the solid walls of target support
18
, or can be a separate device similar to the innertube of an automobile or bicycle tire. Bladder
30
can accept air through inflation point
32
, which can use any conventional means of accepting and holding air. The air in bladder
30
helps target support
18
maintain sufficient rigidity during swing impacts to translate impact energy into rotational motion. In alternative embodiments, the target support and base can each have an independent and separate air bladder. An air bladder in the target can adjust the effect which an impact has by changing the target energy absorption characteristics. Further, when the target
16
and target support
18
are formed as a contiguous unit, bladder
30
can extend into a cavity common to both target
16
and target support
18
.
FIG. 2
depicts a partial cutaway view of apparatus
10
to illustrate an adjusting mechanism for adjusting the vertical height of target
16
when target
16
is in an upright position in preparation for accepting a swing impact. Target support
18
can include an exterior thread
34
and base
20
can include an interior thread
36
, each thread formed in a spiral similar to a screw thread. Alternatively, target support
18
can be coupled securely to base
20
by any conventional means including construction of support
18
and base
20
as a single contiguous unit.
In an embodiment of the present invention that includes a target height adjusting mechanism, target
16
is coupled to a target support
18
having a thread
34
disposed on its exterior surface. Target support
18
is placed into base
20
to engage interior thread
36
of base
20
. The vertical height of target
16
is adjusted by rotating target support
18
relative to base
20
to engage threads
36
and
34
at an appropriate height. After the target height is adjusted to a predetermined level, the position of base
20
and target support
18
can be locked relative to each other by filling air bladder
30
. Air bladder
30
experts pressure against target support
18
to create a force against threads
34
and
36
. The amount of locking force can be increased by increasing the air pressure in bladder
30
.
In operation, swing practicing device
10
is set up in an upright position on its base
20
. Weight, such as sand or lead, is added to base
20
through opening
28
which is then closed off and secured. Alternatively, weight is added by unscrewing target support
18
from base
20
to expose a weight compartment
21
, and then secured by reattaching target support
18
to base
20
. The batter or his coach can adjust the weight added to cavity
21
according to the amount of power of the anticipated swing impact. The batter or coach can also adjust the vertical height of target
16
with the adjusting mechanism according to the height of a proper swing for the batter.
Once swing practicing device
10
is properly set up, a batter can swing at target
16
with full power. Target
16
absorbs the impact of the batter's swing and translates the energy of the swing through target support
18
to base
20
so that the curved edge of rounded bottom
22
rotates in engagement with the ground from the upright position to a more horizontal position. During the rotation, the energy of the swing is dissipated and the weight in base
20
biases target
16
to return to the upright position. The hitter or his coach can judge the characteristics of the swing by observing the direction which target
16
takes and the amount of vertical displacement by target
16
.
Target
16
is firmly coupled to target support
18
so that swing impacts will not separate target
16
from target support
18
. Thus, a batter can repeat his swing repeatedly without chasing target
16
after each swing. Further, the weight and rounded portion of base
20
can be adapted to allow a batter to swing at target
16
when target
16
is in motion towards the upright position to the more horizontal position. In alternative embodiments, target
16
could be shaped to support any hitting sport, such as softball, tennis or racquetball.
Although the present invention has been described in detail, it should be understood that various changes, substitutions and alterations can be made hereto without departing from the spirit and scope of the invention as defined by the appended claims.
