Description

TECHNICAL FIELD AND BACKGROUND OF THE INVENTION

This application claims priority to U.S. Provisional Application No. 61/045,704, filed Apr. 17, 2008.
The present invention relates to an article for holding an object in a stationary position. A particular embodiment of the invention comprises a tee for holding golf balls.
Golf is a popular game, in which players strike a small ball using a variety of clubs, with the object being to get the ball into a distant hole formed in the ground utilizing as few strokes as possible. Generally, when making the first stroke of the ball toward a particular hole, commonly known as “teeing off”, players utilize a tee.
Prior to the present invention, tees have been relatively thin objects made of wood, plastic or other hard material having a stem with a pointed tip at the bottom end and a relatively wider head section at the top. The pointed tip at the bottom is sharp so that it can be inserted into the ground, and the ball is placed on the head section so that it rests at a height above the ground. The player then tees off by swinging his club at the ball on the tee.
A problem associated with such prior art tees is the fact that the ground may be hard, and it can be difficult to get the tee into the ground. Also, because the typical prior art tee is relatively thin, a significant wind can easily blow the ball off the tee. In an effort to overcome the aforesaid problems, the present invention was conceived.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS AND BEST MODE

A golf tee according to a preferred embodiment of the invention is shown in FIGS. 14, and shown generally at reference numeral 10. As shown in FIG. 1, the golf tee 10 generally comprises a base section 12 for positioning on the ground, and an upper head section 14 for holding the golf ball “B”.
The interior of the head section 14 is concaved such that the head section 14 cradles the ball “B” in the interior of the head 14. As shown in FIG. 2, a front section 14 a of the head is lower than the rest of the head 14 so that a greater portion of the ball “B” at front side 14 a is exposed to the players club. Also, the base 12 extends outward from the bottom of the front side 14 a to define a notched section 16. The low cut front section 14 a and the notched section 16 provide an area for the player's club to strike the ball “B”. The player stands at the tee 10 such that the player faces substantially perpendicular to the front section 14 a of the tee head 14, and the player swings his club such that the club approaches the tee 10 from the front section 14 a and strikes the ball “B”.
As shown in FIG. 1, the base section 14 is preferably graduated in area from the top down in order to improve stability and keep the ball “B” on the tee 10. The tee 10 is made of a relatively light foam-like material, such as polyurethane foam. As such, the tee 10 can be placed anywhere on the ground, including uneven areas, and the tee 10 remains upright without any portion of the tee 10 being inserted into the ground.
A golf tee according to an alternative embodiment of the invention, is illustrated in FIGS. 5-6, and shown generally at reference numeral 50. As shown in FIG. 5, the golf tee 50 has four prongs 54 a-d extending upwardly from a base section 52. The golf ball “B” is held within the four prongs 54 a-d, and the player's club strikes the ball “B” in the area between prongs 54 a, 54 b, shown in FIG. 6.
A golf tee according to another preferred embodiment of the invention is illustrated in FIGS. 7-12, and shown generally at reference numeral 100. As shown in FIG. 7, the golf tee 100 generally comprises a base section 112 for positioning on the ground, and an upper head section 114 for holding a golf ball. The head section 114 has a concave interior 115 that cradles the ball. The tee 100 is frusto-conical in shape, with the top of the upper section 114 having the smallest diameter. The tee 100 graduates in size downward, with the bottom of the base section having the largest diameter of any part of the tee 100. As such, the tee 100 remains stable on the ground without being inserted into the ground.
The tee 100 is made of an elastomeric material, such that the tee readily returns to its original shape after being deformed, compressed, etc. For example, the tee 100 can have a Young's modulus of about 0.025 (E, Gpa). Preferably, the tee 100 is made of a polymeric foam, such as polyurethane foam and/or ethylene vinyl acetate foam. As such, the tee 100 is light and does not travel far or cause damage when struck by a golf club.
For ease of reference, the tee 100 can be divided in half into two vertically oriented semi-cones 101, 102, defined by axis “X” shown in FIG. 9. A notch 116 is formed in the first semi-cone 101 of the tee 100, as shown in FIGS. 8, 9 and 11. Also formed in the first semi-cone are four slits 121, 122, 123, 124. The slits 121-124 create four movable flaps 114 a, 114 b, 114 c, 114 d in the head section 114 for absorbing force from a golf club head swung at the ball.
As shown in FIGS. 7 and 9, a pointer 118 extends outwardly from the outer surface of the second semi-cone 102 of the tee 100. The pointer 118 is located on the tee 100 approximately 180 degrees from the notch 116. A plurality of vertically oriented ridges 128 can also be formed on the outer surface of the second semi-cone 102 to assist the user in grasping the tee 100.
In use, the tee 100 is placed on the ground where the user wishes to tee off, with the base section 112 being proximate to the ground. The tee 100 is oriented such that the pointer 118 is pointed toward the green. As such, the notch 116 and the collapsible flaps 114 a-d are facing the golf club head as the user swings his club to tee off. The pointer 118, which is pointed toward the green, provides visual direction to the user of the location of the green as he keeps his head down while swinging his club. When the user swings his club, the notch 116 exposes the ball to the club head providing a clear shot to the ball, and the moveable flaps 114 a-d absorb the force of the swinging club head. A golf tee and method of using same are described above. Various changes can be made to the invention without departing from its scope. The above detailed description of the preferred embodiments and best mode of the invention are provided for the purpose of illustration only- the invention being defined by the following claims and equivalents thereof.
