DESCRIPTION OF THE PREFERRED EMBODIMENT

Although the disclosure hereof is detailed and exact to enable those skilled in the art to practice the invention, the physical embodiments herein disclosed merely exemplify the invention which may be embodied in other specific structures. While the preferred embodiment has been described, the details may be changed without departing from the invention.

FIG. 1 illustrates a golf swing practice device or golf ball holder 10 having a tubular, modular arrangement. The ball holder 10 comprises a base 12 that rests on a surface 14. In the illustrated embodiment, the base 12 comprises a front leg 16, a rear leg 18, and a pair of opposed side legs 20 which are coupled together by a series of base elbows 22 or other suitable coupling means. Extending upright from the front leg 16 of the base 12 is a post 24. The post 24 is positioned at an approximately 90 degree angle relative to the base 12 or other suitable angle. The post 24 is desirably coupled to the base 12 by a T-fitting 26 or other coupling means. An arm 28 extends from the post 24 at an approximately 90 degree angle relative to the post 24 in a direction opposite the base 12 and may be coupled to the post 24 by an elbow 30. An endcap 32 may be placed over the free end 34 of the arm 28 to provide a smooth surface at the free end 34. Elbows 22 and 30 and T-fitting 26 may be secured in the assembled position by screws or other fastening elements for additional stability. If permanent assembly is desired, elbows 22 and 30 and T-fitting 26 may by permanently fixed by adhesive.

In a preferred embodiment, the individual modular components of the ball holder 10 are formed of a lightweight and durable material and are of a hollow, tubular configuration. The modular arrangement provides for easy assembly and disassembly of the ball holder 10 for transport. The ease of transport and assembly allows the ball holder 10 to be used in a variety of both indoor and outdoor settings. While the illustrated embodiment shows a base 12 having a square configuration, the base 12 may be sized and configured in any suitable manner which permits the ball holder 10 to rest securely in an upright position, e.g., rectangular. The ball holder 10 is desirably also configured to rest on various surfaces, e.g., outdoors on lawn or payment, or indoors on carpet or hard flooring.

A first end 36 of a string or tether 38 is tied to the arm 28 near the arm free end 34 such that the end 36 is fixedly attached to the arm 28 and therefore not free to rotate circumferentially around the arm 28. In the illustrated embodiment, the arm 28 includes a pair of holes 40 through which the string 38 may be passed. In an alternative embodiment, the string 38 may be tied to the arm 28 by use of a ring or eyelet extending from the arm 28 (not shown). A practice ball 42, desirably a lightweight plastic ball, is tied to the other end 44 of the string 38, e.g., by an eyelet 46. The string 38 has a length such that the ball 42 just touches the surface 14. The length may be selected so as to accommodate placement of a conventional golf tee beneath the ball 42 if desired (not shown). FIG. 2 illustrates an alternative embodiment of a practice ball 42′ in which the ball 42′ is a slotted wiffle-type ball. The string 38 may be passed through one or more slots 48 to secure the ball 42′ to the string 38.

In use, the golfer assures that the string 38 is not wrapped around the arm 28 and that the ball 42 just touches the surface 14. The golfer then strikes the ball 42 with a club 50, as shown in FIG. 3. Because the end 36 is not free to rotate, the string 38, or at least a portion of it, will wrap around the arm 28 upon striking of the ball 42 while remaining tethered to the ball 42, as shown in FIG. 4.

With reference again to FIG. 1, the base 12 may also provide a means for securing a second practice ball 42 to the ball holder 10 at a position along the base 12. In the illustrated embodiment, the rear leg 18 of the base 12 includes a pair of holes 52 for receiving a pin 54 or other anchoring device which may be driven into the ground 14, making the ball holder 10 well-suited to outdoor use. The pin 54 may include an eyelet 56 or other means for tying a first end 36 of a string 38 to the pin 54. The practice ball 42 is tied to the other end 44 of the string 38, e.g., by an eyelet 46, as previously described.

FIG. 5 illustrates use of the second practice ball 42. The golfer first secures the pin 54 in the ground surface 14 and positions the ball 42. In desired, the ball 42 may be placed on a conventional golf tee (not shown). The golfer then strikes the ball 42 with the club 50 to move or advance the ball 42 to the full extension of the string 38 while the ball 42 remains tethered to the pin 54.

The foregoing is considered as illustrative only of the principles of the invention. Furthermore, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described. While the preferred embodiment has been described, the details may be changed without departing from the invention.
