DESCRIPTION
[0022] The invention relates to an improved batting aid device. The
device can be used by right-handed or left-handed hitters, and be
operated individually or with a partner. The device is designed to
improve hand-eye coordination, reflexes, muscle memory, and timing
in hitting a ball with a bat, and to develop a quicker, more
compact swing. In preferred embodiments, the device is adjustable
to allow increasing or decreasing levels of difficulty, is
adjustable to different heights, and is foldable for easy storage
and transport.
[0023] In general, the device includes a stand having a bottom
portion and a top portion and a plastic tube attached to the top
portion. A ball, for example a baseball, wiffle baseball, or wiffle
golf ball can be placed in the tube at a first end of the tube or
at a position along the tube. The tube is positioned such that the
ball will travel by gravity to a second end of the tube and exit
the tube at a selected exit angle, e.g. straight downward, 45
degrees, etc. Preferably the tube is opaque so as to prevent the
user from visualizing the ball as it travels in the tube.
[0024] As the ball exits the end of the tube, the user can
visualize the ball and attempt to hit it with a bat, stick or the
like.
[0025] In preferred embodiments, the stand of the device includes
two legs at the bottom portion wherein one leg is collapsible, and
further preferably includes multiple telescoping sections. The
multiple telescoping sections allow the device to be adjusted to
different heights to accommodate the stature of the user. In one
embodiment, the stand includes two legs with one leg collapsible,
and three telescoping sections that allow the device to be adjusted
between twenty-four inches tall and sixty-six inches tall. A stand
with the foregoing features has the additional advantage of being
folded and compacted to fit within a small space such as the trunk
of an automobile. All elements of the device can be fabricated from
any desired material. The stand, for example, may be fabricated
from metal to add weight and stability to the device, or may be
fabricated from plastic to provide a more lightweight device, e.g.
for small children to use. The hollow tube and rotatable mechanism
are preferable fabricated from plastic or other lightweight
material to prevent the device from being top heavy. The tube can
be a single piece or have multiple sections as desired for
versatility or compact storage. Preferably the tube and rotatable
mechanism are fabricated from injection-molded plastic.
[0026] The tube may be attached to the top portion of the stand
using any suitable means, for example a metal ring or clamp adapted
to tightly fit around the tube and be attached to the top portion
of the stand, preferably in conjunction with an adjustable dial or
knob used to connect the ring holding the tube to the stand. The
plastic tube may be "L" shaped, or preferably as a generally
sideways "V" and include multiple sections that allow for
disassembly or multiple adjustments. In a sideways "V"
configuration, a user can load the device with a ball at the first
end of the plastic tube (the upper end of the sideways "V", and
remain in position to hit the ball as it exits the second end of
the tube (the lower end of the sideways "V". The plastic tube may
also be a single, molded tube. The means of attachment of the tube
to the stand may further include a knob to adjust the plastic tube
such that a ball placed in the tube travels downward toward the
second end of the tube by the force of gravity. The plastic tube
may further include, at its second end, a mechanism that allows
adjustment of the exit path for the ball. The mechanism may
include, for example, a curved section of plastic tubing that may
be fitted, via a fitting designed to slide onto the second end of
the tube, allowing adjustment of the angle of exit of the ball.
Such adjustability is particularly advantageous for altering the
degree of difficulty in hitting the ball exiting the tube, with a
straight vertical downward path providing a higher degree of
difficulty than, for example, a horizontal or angled path.
[0027] FIG. 1a depicts a device according to the invention, as
described above. The device 1 includes a stand 2, wherein the stand
includes two legs 3 and 4. Leg 4 is collapsible toward leg 3. Legs
3 and 4 may further include, feet 3a and 4a, as shown in FIG. 1a.
Legs 3a and 4a extend perpendicularly from the legs 3 and 4 at the
base of legs 3 and 4. In one embodiment, feet 3a and 4a include
telescoping sections that allow the feet to be extended and provide
further stability to the device during use, and allow the device to
be more compact when stored or transported. The stand further
includes telescoping sections 5, 6, and 7. In the embodiment shown
in FIG. 1a, hollow plastic tube 8 is attached, at attachment 9, to
a top portion 10 of stand 2. The hollow tube 8 is preferably
adjustably rotatable about attachment 9. Plastic tube 8 includes
three sections 11, 12, and 13. The plastic tube 8 has a first open
end 14 and a second open end 15. A mechanism 16 for altering the
exit path of a ball is shown in FIG. 1a as a curved piece of
plastic tubing. The curved piece of tubing is open at its two ends;
one end includes a fitting adapted to be attached to second end 15
of plastic tube 8. In this embodiment, the rotatable mechanism is
infinitely adjustable to provide the exit angle, by simply rotating
the mechanism as it engages with the second end of the tube.
[0028] FIG. 1b shows another embodiment of the invention and
illustrates additional features of the improved batting device.
Telescoping sections 5, 6, and 7 of the stand 2 can be adjusted to
a preferred height by the use of pins 17 placed through aligned
holes in the interlocking sections 5, 6, and 7. In addition, FIG.
1b shows a dial 18 at the attachment 9 of the stand 2 to the tube
8, which allows the tube 8 to be adjustably rotated such that a
ball placed in the tube will travel by force of gravity. FIG. 1b
also shows the optional feature of an opening 32 in the tube 8. The
opening can be positioned at any desired point in the length of the
tube. Opening 32 provides an alternative position for feeding balls
into the device, for example for a partner to stand clear of the
user while loading the device, as well as an alternative position
to place a ball holding device such as that depicted in FIGS. 2A
and 2B.
[0029] In use, a ball is placed in the first end 14 of the hollow
plastic tube 8. The ball travels, by force of gravity, to the
second end 15 of the tube, and exits the tube in a path prescribed
by the rotatable position of the mechanism 16. The user may then
attempt to hit the exiting ball with a stick, bat, or the like. The
user may start with and exit angle, ball size, and bat that make it
relatively easier to strike the ball, and then vary the angle, bat
(e.g. a stick bat), and ball size (e.g. reduce from wiffle baseball
to wiffle golf ball) to increase the degree of difficulty.
[0030] FIGS. 2A and 2B depict another preferred embodiment of the
device. The device shown in FIG. 2A includes a stand similar to
that shown in FIG. 1. The device of FIG. 2A also contains a plastic
tube attached to a top portion of the stand. The device of FIG. 2A
includes the additional feature of a ball holding apparatus 20
attached at the first end 14 of the plastic tube. The ball holding
apparatus is capable of holding many balls, and may be attached at
any desired position along the length of the tube. The ball holding
apparatus allows a user to continuously hit one ball after the
other after it exits the tube without having to manually load
single balls. The ball holding device may be automated to feed
balls to the device, or may be a receptacle to store multiple balls
for manual loading.
[0031] A ball holding apparatus in accordance with the invention is
depicted in FIG. 2B in side and top views. The elements of the ball
holding apparatus are shown in detail in FIG. 2B.
[0032] In general, the ball holding apparatus 20 includes a plastic
bucket 31 containing a plate 27 (plate 27 preferably being metal).
Bucket 31 has an opening in its bottom to allow balls to pass
through into the tube, and is adapted to fit onto tube 8, e.g. by a
collar or other fitting designed to mate with an opening in the
tube 8. A motor 21 (preferably battery operated) that turns plate
27 (by pulleys 22 and 24 and rubber belt 25) and is designed to
drop a ball out of the apparatus at a time interval, e.g. about
every ten seconds, through a hole 23 in the plate sized to permit
passage of a ball of desired diameter. A vertical pulley 22 on the
motor is connected to a horizontal pulley 24 on the partially
threaded stud by rubber belt 25. The rubber belt 25 may be designed
to slip to prevent injury resulting from placing a finger or hand
into the moving apparatus. The apparatus includes "L" tab with
wheels 26 to keep the metal plate 27 balanced and easy to turn.
Tabs 28 on the metal plate are designed to drop a ball into a hole
and prevent jamming of the balls. The plate may advantageously
include multiple holes 23 and 29 sized to generally fit the size of
the balls being used in the device, for example three inches for
baseball-sized balls and one and a half inches for wiffle golf
balls. This feature allows the device to be adaptable for use with
differently sized balls. A three-inch cap 30 may be used to plug a
three-inch hole 23 when golf ball sized balls are used in the
device. A "U" shaped steel bracket 32 may be included, and is
designed to allow a ball to partially drop down in the hole, and
thereby prevent the ball from easily popping out of a hole.
[0033] Additional embodiments of the invention feature alternatives
to the mechanism 16 for altering the exit path of the ball. FIGS.
3a and 3b illustrate one such alternative. In this embodiment of
the device, the second end 15 of the tube has a circumferential
recessed groove 40 about at least a portion, preferably the
entirety, of the circumference of the tube near second end 15,
wherein the recessed groove contains a plurality of raised portions
spaced apart at selected intervals within the groove 40. Rotatable
mechanism 42 contains a ring portion 43 for mating with second end
15, and dial tube 44, which is the exit point for a ball. Ring
portion 43 has an inner surface 45, and one or more detents 46 on
the inner surface 45. As shown in FIG. 3a, the ring 43 contains a
plurality of generally "U" shaped slots, with detents 46 on the
inner surface 45 surrounded by the "U" to provide a snapping
portion of the ring portion for snapping into the groove. This
configuration allows mechanism 43 to snap onto second end 15, by
positioning the detent 46 into the groove 40. This snapping action
is illustrated in FIG. 3b. Once the mechanism 42 is snapped onto
the second end 15, the mechanism can be indexed to a desired
distinct position by rotating the mechanism to snap out of and into
index positions defined by raised portions 41, thus allowing for
adjustment of the exit angle of a ball emerging from second end 15
through the mechanism 42.
[0034] FIGS. 4a and 4b illustrate another alternative for the
mechanism for altering the exit path of the ball. In this
embodiment, second end 15 of the device contains a plurality of
holes 50 arranged and spaced apart circumferentially near the
second end 15 of the tube 8. Rotatable mechanism 51 contains a dial
end portion 52 and a ring portion 53, and at least one spring
loading pin 54 and spring 55 (shown in exploded view in FIG. 4a),
wherein the spring loading pin is adapted to be fastened to the
ring portion 53. The spring loading pin 54 extends through and
protrudes from the inner surface 56 of the ring portion 53, and is
adapted to engage with the holes 50 in second tube end 15, with the
ring portion 53 is placed over the second end 15. The spring
loading pin 54 is further adapted to move out of and into holes 50
as the mechanism 51 is rotated to index the mechanism at a desired
position that will provide a desired exit path for a ball emerging
from the mechanism 51. In the embodiment shown in FIG. 4a, a
housing 57 covers the spring loading pin 54 and spring 55 and is
attached with screws 58 to the ring portion 53. In the embodiment
shown in FIG. 4b, there are two spring loading pins 54 in the
mechanism 51. As shown in FIG. 4a, the mechanism 51 may be
comprised of separate ring 53 and dial end portion 52, with the
ring 53 attached to the dial end portion 52 by one or more pivot
pins 59. In this embodiment, the device would be assembled by
attaching the ring 53 (containing the spring loading pin(s) 54 for
indexing) to the dial end 52 by engaging the pivot pin(s) 59 with
holes in the ring 53. The mechanism 51 comprising the dial end 52
and ring 53 is then placed over the first end 14 of the tube 8 such
that the spring loading pin(s) 54 engage with holes 50. The
mechanism 51 can then be rotated and locked into desired distinct
positions for determining the exit path of the ball.
[0035] The devices of the invention preferably are used in
conjunction with a stepwise hitting process to develop hand-eye
coordination and a quicker swing for hitting a baseball or
softball. In general, a stepwise hitting process may include steps
in which parameters of the process are varied. Parameters of the
process that may be varied include the type of instrument (baseball
bat, stick bat), the size of the ball.(baseball-size, golf ball
size), and the exit path of the ball (substantially directly toward
the user, e.g. a generally horizontal exit path; at an angle, e.g.
45 degrees; and substantially straight down or vertical). In
general, the method involves increasing the degree of difficulty of
hitting the ball with each step, by varying at least one parameter
of the process, with the end result being improvement in hand-eye
coordination and swing speed. For example, a first step may include
using a baseball bat to hit wiffle baseballs as the balls come
toward the user; a second step could include using a stick bat to
hit wiffle baseballs coming toward the user; a third step and
fourth step could repeat the first step and second step using
wiffle golf balls. These four steps can then be repeated with the
ball exiting the device at a forty-five degree angle, and repeated
again with the ball dropping straight down.
[0036] An example of a twelve step hitting process that can be used
in conjunction with the device of the invention is as follows:
[0037] Step 1. Use a baseball bat to hit wiffle baseballs as the
balls come toward you.
[0038] Step 2. Use a stick bat to hit wiffle baseballs as the balls
come toward you.
[0039] Step 3. Use a baseball bat to hit wiffle golf balls as the
balls come toward you.
[0040] Step 4. Use a stick bat to hit wiffle golf balls as the
balls come toward you.
[0041] Step 5. Use a baseball bat to hit wiffle baseballs as the
balls come at 45-degree angle.
[0042] Step 6. Use a stick bat to hit wiffle baseballs as the balls
come at 45-degree angle.
[0043] Step 7. Use a baseball bat to hit wiffle golf balls as the
balls come at 45-degree angle.
[0044] Step 8. Use a stick bat to hit wiffle golf balls as the
balls come at 45-degree angle.
[0045] Step 9. Use a baseball bat to hit wiffle baseballs as the
balls drop straight down.
[0046] Step 10. Use a stick bat to hit wiffle baseballs as the
balls drop straight down.
[0047] Step 11. Use a baseball bat to hit wiffle golf balls as the
balls drop straight down.
[0048] Step 12. Use a stick bat to hit wiffle golf balls as the
balls drop straight down.
[0049] Other embodiments of the invention are within the scope of
the appended claims.
