BATTING TEE APPARATUS
Abstract
Improved batting tee apparatus useful in teaching the
fundamentals of hitting a baseball properly. The tee includes a
base that is supported on a member which simulates, or is "home
plate." Tubes extend upwardly from the base and are in telescoping
relation for height adjustment. A rubber ball support is connected
to the uppermost tube and is adapted to support a baseball. The tee
apparatus may be shifted at will to various locations relative to
home plate to simulate high, low, inside or outside pitches and, as
a safety measure, may be easily and quickly removed from the home
plate area when a runner on third base attempts to score a run. The
upwardly extending tubes comprise first and second tubes wherein
the upper end of the first tube is provided with an inner bushing
for receiving the lower end of the second tube. The second tube is
held in the first tube by a thumb screw which extends through the
first tube and bushing and abuts the lower end of the second tube.
The upper end of the second tube is provided with a tubular ball
support. The ball support is provided with a series of spaced apart
grooves to enhance frictional engagement with the second tube when
telescopically inserted therein.

Description
BACKGROUND AND SUMMARY
Batting tees are known in the prior art and have been used in
Little Leagues in the playing of the game of baseball. In such use,
most of the rules of the game of baseball are observed, but a
notable exception is that the pitcher does not throw the ball
toward the batter and this has two beneficial effects. First, the
pitching arm of a very young player is not developed to the point
where it will withstand the rigors of pitching. Many arm problems
have been developed by youngsters who tried to emulate the
professional players. Secondly, ball control is difficult for a
young pitcher and oft times a batter is hit by a pitched ball. In
use of batting tees, instead of the pitcher throwing the ball, he
merely assumes a fielding relationship around the pitcher's mound,
and the catcher places the ball on the batting tee for the batter
to hit.
In the prior art known to me, the batting tees are usually
connected to home plate and thus present a hazard when a runner
from third base attempts to score. Further, such prior art tees are
not designed to combine light weight with sturdiness and stability.
My invention provides a batting tee that has been engineered to
provide the utmost in safety to the players, and to withstand the
rigors of play.
DESCRIPTION OF THE DRAWING
In the drawing accompanying this description and forming a part of
this application, there is shown, for purpose of illustration, an
embodiment which my invention may assume, and in this drawing:
FIG. 1 is a perspective view of my improved batting tee apparatus,
showing a player in process of striking a ball supported on the
tee,
FIG. 2 is an enlarged, longitudinal sectional view of the
apparatus, with the ball support shown in full,
FIG. 3 is an enlarged, broken sectional view of the ball support,
and
FIG. 4 is an enlarged, fragmentary sectional view of a detail.
DESCRIPTION OF THE PREFERRED EMBODIMENT
My improved batting tee apparatus comprises a base 10, preferably
formed of metal, such as cast aluminum. As seen in FIGS. 1 and 2,
the base is preferably round in plan view and slightly dished to
provide an annular, rounded lower edge 11. The base may be webbed,
as shown at 12, to reduce mass, and is formed with a central,
upstanding socket 14. The rounded corners of the base provide a
safe support since it eliminates all dangerous sharp edges that
might produce injuries. The base formed as shown in the drawing
provides a light-weight support for the tee, and uniform stability
in every direction.
Secured in the socket 14 is the lower end of a tube 15 which is
preferably formed of aluminum tubing to provide a light-weight but
rigid post. A set screw 16 is threaded through the wall of the
socket 14 and against the wall of the tube 15 to hold the latter
securely attached to the base 10. The set screw is of the socket
head type and of a length so that its outer end does not extend
outwardly of the socket 14 to thereby remove another element of
injury.
A bushing 17 is disposed within the upper end of the tube 15 to
provide for trouble-free sliding movement of a second aluminum tube
18 which is telescopically received within the tube 15. As seen in
the drawing, the tube 15 preferably has a greater wall thickness
than the tube 18. The bushing 17 is preferably formed of bronze and
has a press fit with the interior of the tube 15 so that it is
firmly anchored therein. As best seen in FIG. 4, the lower end of
tube 18 has an out-turned flange 19 which has a sliding fit with
the inner wall of tube 15 and thus steadies the lower end of tube
18. A thumb screw 20 is threaded through the tube 15 and bushing 17
and its inner end bears against the wall of tube 18 to hold the
latter in adjusted vertical position.
A resilient ball support 21 is disposed at the upper end of tube 18
and it has been found preferable to form this support of molded
natural rubber. The support is designed to provide maximum ball
exposure and positioning, and the required resilience to withstand
repeated impact of the bat with the ball, or in cases of misses,
the bat with the support.
As best seen in FIGS. 2 and 3, the support 21 comprises a lower end
22 adapted to have a close and gripping fit within the upper end of
the tube 18. To assist in insertion of the lower end 22 within the
tube 18, a tapered pilot 23 is formed at the lower extremity. The
lower end 22 is hollow, as shown at 24, so that it will be slightly
compressed during insertion into the tube 18 and will thereafter
expand into gripping relation with the tube wall. A plurality of
annular grooves 25 are formed in the lower end 22 to provide
gripping edges for firm engagement with the inner wall of the tube
18.
A rounded annular flange 26 is formed intermediate the ends of the
ball support 21 to engage the upper end of the tube 18 and limit
insertion of the lower end 22 into the tube. Upwardly of the flange
26, the support is in the form of a relatively long, narrow neck 27
which tapers gradually to a slightly enlarged size, as at 28, where
it is integrally joined to a flaring upper end 29. A conical recess
30 is formed inwardly of the upper end 29 to provide optimum ball
support and a view of the ball B with a minimum of lip exposure so
as not to interfere with the flight of the batted ball. It will
thus be seen that the ball support 21 provides a long, narrow
silhouette to give the ball a greater dimension of exposure to the
view of the batter.
As seen in FIG. 1, the diameter of the base 10 is less than the
width or length of home plate H and since the base 10 merely rests
on home plate it may be easily moved to various positions therein
to simulate various inside and outside pitches. Since the base 10
has uniform stability in every direction, the batting tee apparatus
will not be easily overturned in the event the batter misses the
ball and strikes the rubber ball support 21, and the resiliency of
the latter will absorb the shock of the swing without imparting any
shock of the blow to the batter. Further, since the entire tee
apparatus is of light weight, it may be easily brushed aside and
out of the way of a runner attempting to score from third base, and
therefore prevent injury to the runner. In the event that the wing
screw 20 is not adequately tightened, the flared end 19 of the tube
18 will prevent the latter from being inadvertently withdrawn from
the tube 15. In this respect, it should be noted that the tube 18
is assembled by moving its upper end through the lower end of the
base 10 and tube 15.
My improved tee apparatus may be used in the customary manner in
game play, or it may be used out of play so that an instructor,
knowledgeable in the skill of hitting a baseball, may instruct a
novice to become a good hitter .
