NON-INTERFERING GOLF TEE
Abstract
A golf tee designed in such a manner that a golf ball driven off
the tee does not encounter a section of the tee which obstructs the
trajectory of the golf ball. The golf tee includes a specially
designed head section having a top with an upward opening curved
rear surface. A ramped surface extends forward from the curved rear
surface to the front of the tee and is inclined slightly above the
horizon. The ramped surface has an upward opening curvature
extending from side to side across the head which, in combination
with the rear curved surface, supports a golf ball placed on the
tee. The front of the head section has a forward opening curvature
extending from side to side across the head which also assists in
preventing an obstruction to the trajectory of a golf ball driven
off the tee.

Description
BACKGROUND OF THE INVENTION
The present invention relates generally to golf tees, and more
particularly pertains to a new and improved golf tee which allows a
golf ball to be driven off the tee without the golf tee obstructing
the trajectory of the golf ball.
It has been the general practice to construct the top of a golf tee
with a circular lip to support the golf ball. These prior art golf
tees have been unsatisfactory in that the portion of the circular
lip located in the front on the tee is positioned in the trajectory
of a golf ball driven off the tee, and actually obstructs a well
hit ball. Although the obstruction is relatively slightly when
considering the normal force with which a golf ball is driven off
the tee, the obstruction nevertheless exists and has an adverse
affect upon the trajectory of the golf ball which results in the
golf ball being driven a shorter distance. It would be desirable to
have a golf tee constructed in such a manner that a golf ball
driven off the tee does not encounter a section of the tee as an
obstruction to the trajectory of the golf ball.
SUMMARY OF THE INVENTION
In accordance with a preferred embodiment, an improved golf tee is
disclosed which is constructed in a manner such that a golf ball
driven off the tee does not have its trajectory obstructed by a
portion of the golf tee. In accordance with a preferred embodiment
the head of the golf tee, which supports the golf ball, has a top
with an upward opening rear surface. A slightly upward inclined
ramped surface extends forward from the curved rear surface to the
front of the tee. The ramped surface is flat along the direction in
which the golf ball is driven, which allows the front lip normally
present in most prior art golf tees to be eliminated. Further, the
preferred embodiment provides such a golf tee wherein the ramped
surface has an upward opening curvature extending from side to side
across the head section. Still further, the preferred embodiment
provides a golf tee wherein the front of the head section has a
forward opening curvature extending from side to side across it.
Also, the preferred embodiment provides such a golf tee wherein the
center of gravity of a golf ball placed on the tee is directly over
the pointed end of the base section. Further, the preferred
embodiment provides a golf tee wherein the base section includes a
shaft extending along a shaft axis, and the shaft axis is inclined
forward a slight predetermined angle relative to a vertical when
the golf tee is inserted into the ground. Still further, the
preferred embodiment provides a golf tee wherein the ramped surface
joins the curved rear surface approximately at the center of the
golf tee, and further wherein the front-to-back and the
side-to-side dimensions of the tee head are both approximately
equal to one third the diameter of a standard golf ball. Also, the
preferred embodiment provides a golf tee wherein the bottom of the
head section has a shoulder which prevents the golf tee from being
inserted into the ground beyond the shoulder.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 illustrates a perspective view of a preferred embodiment of
a golf tee constructed according to the teachings of this
invention.
FIGS. 2, 3 and 4 are respectively front, side and top views of the
preferred embodiment.
DESCRIPTION OF A PREFERRED EMBODIMENT
FIG. 1 illustrates a perspective view of a preferred embodiment of
a golf tee built according to the teachings of this invention.
Reference should be made to FIG. 1 and also to FIGS. 2, 3 and 4,
which are respectively front, side and top views of the golf tee,
for a more complete understanding of this invention. The golf tee
has a pointed base section 12, which is utilized to insert the golf
tee into the ground, and a head section 14 which is utilized to
support a golf ball placed on the tee. The top of the head section
is constructed in a manner which allows a golf ball to be driven
off the tee without the tee obstructing the trajectory of the ball.
The top of the head section includes a curved rear surface 18 and a
ramped surface 20 extending from the curved surface to the front of
the tee. The rear surface 18 has an upward opening curvature
extending across the width of the tee, as shown best in FIG. 2, and
also extending from the back of the tee to the middle 16 of the
tee, as illustrated best in FIG. 3. The radius R of the curvature
of this section is approximately equal to the radius of a golf ball
22, shown in phantom in FIG. 3. This curvature of the rear surface
enables a golf ball placed on the tee to rest flush against the
entire area of the rear surface. A ramped surface 20 extends
forward from the mid point 16 of the tee, where the curved rear
section 18 ends, to the front of the tee. The ramped surface 20 is
inclined a predetermined angle .alpha. above the horizon
illustrated at H. As shown best in FIGS. 2 and 3, the ramped
surface 20 is flat in the direction in which a golf ball is driven,
and has an upward facing curvature extending from side to side
across the golf tee as best shown in FIG. 2.
As illustrated in FIG. 3, the front to back mid point 16 of the top
of the golf tee is located directly over the base point 24 of the
tee. The base 12 of the golf tee has its shaft extending along a
shaft axis 26. The geometry of this construction is such that when
the golf tee is inserted into the ground and a golf ball placed on
the tee, the center of the golf ball lies directly over the center
16 of the golf tee and also directly over the point 24. Stated
differently, the center of the golf ball, the mid point 16 of the
golf tee and the point 24 all lie along a vertical axis illustrated
at V. This results in the shaft axis 26 being inclined slightly
forward relative to the vertical V by a predetermined angle
.beta..
FIGS. 3 and 4 illustrate another feature of this invention. The
front of the golf tee is constructed with a forward opening
curvature 21 which extends from side to side across the head of the
tee. This forward opening curvature is designed to eliminate a
possible slight obstruction to the trajectory of a golf ball which
might otherwise be presented by the bottom forwardmost edge of the
ramped surface.
In the preferred embodiment the bottom of the tee head 14 forms a
shoulder 28 where it joins the tee base 12. This shoulder prevents
the golf tee from being inserted into the ground beyond the
shoulder. If the golfer so desires he may insert into the ground to
the shoulder, thereby positioning the golf ball a predetermined
distance above the ground as defined by the height of the tee
head.
In the preferred embodiment the front to back and the side to side
dimensions of the tee head are both one third of the diameter of a
standard golf ball, as illustrated in FIG. 4. These dimensions
assure that the tee provides a stable base for a golf ball placed
upon it.
With a golf tee constructed according to the teachings of this
invention, the obstruction provided by front lip of a golf tee,
which normally obstructs the trajectory of a well driven golf ball,
is eliminated. While several embodiments have been described, the
teachings of this invention will suggest many other embodiment to
those skilled in the art.
