PREFERRED EMBODIMENTS FOR CARRYING OUT THE INVENTION

[0022] A tennis racket made in accordance with one embodiment of the present invention is indicated generally by the numeral 10 in FIG. 1. Racket 10 includes a generally oval frame 11, a handle 12, and a V-shaped neck 13 between handle 12 and frame 11. An opening 14 is formed between neck 13 and the bottom of frame 11. A plurality of strings 15 are conventionally mounted within frame 11.

[0023] Frame 11 is provided with a peripheral groove 16 which receives a vibration dampening member 17. Dampening member 17 can be a visco-elastic polymer such as rubber, neoprene, silicone and the like, all of which having a high vibration dampening coefficient. An ideal material for dampening member 17 is a thermoset, polyester-based, polyurethane material sold by Sorbothane, Inc. under the trademark SORBOTHANE®.

[0024] If desired, dampening member 17 can extend out of groove 16 to protect racket 10 should an edge of frame 11 hit the ground or another object. In this situation, the outer peripheral surface of member 17 can be rounded or dimpled so as to improve the air flow around the racket as it is being used. As another alternative, if the user of the racket 10 would desire to alter the weight distribution of the racket, small weights could be embedded in the dampening member 17 at selected locations. Finally, an additional dampening affect can be optionally provided by filling opening 14 with a vibration dampening material.

[0025] One configuration of dampening member 17 is shown in FIG. 4. A generally oval loop 18 is formed and is of a size somewhat less than the peripheral size of frame 11. A somewhat oval ring 19 is formed at the bottom of loop 18. A dampening member 17 is installed on frame 11 by threading handle 12 and neck 13 through ring 19 and stretching loop 18 so that it can be snugly received in groove 16 when it is relaxed.

[0026] An alternative embodiment of the present invention is shown in FIG. 5. There, the racket is generally indicated by the numeral 20 and includes a frame 21, a handle 22, and a V-shaped neck 23 forming an opening 24. A plurality of strings 25 are conventionally mounted within frame 21.

[0027] In this embodiment a vibration dampening member 26 is attached, as by glue or the like, to the outer periphery of frame 21. Dampening member 26 may be made of the same material as dampening member 17 and cannot only dampen the vibrations when strings 25 contact a ball, but also can protect racket 20 should the edge of frame 21 hit the ground or another object. In this embodiment, the alternative features described with respect to racket 10 could also be provided. That is, the dampening member 26 may be provided with a rounded peripheral edge for aerodynamic efficiency and also could receive weights to provide a desired racket weight distribution.

[0028] It is also contemplated that the dampening member 26 of racket 20 could be mounted inside of frame 21. Such would provide strings 25 with direct contact with the dampening member 26 for vibration control.

[0029] FIG. 6 depicts yet another embodiment of a racket made in accordance with the present invention which is generally indicated by the numeral 30. Like the other embodiments, racket 30 includes a frame 31, a handle 32, and a V-shaped neck 33. A plurality of strings 34 are conventionally mounted within the frame 31.

[0030] In this embodiment, a vibration dampening member 35 is positioned within the opening in neck 33 and attached thereto by glue or the like. Dampening member 35 may be made of the same material as dampening members 17 and 26. Racket 30 would be particularly useful where extreme vibrations, which could be dampened by rackets 10 and 20, are not expected or do not need to be accommodated.

[0031] In view of the foregoing, it should be evident that a racket made in accordance with any of the embodiments described herein accomplishes the objects of the present invention and otherwise significantly improves the art.
