Abstract
A tennis racket (10) carries strings (13) which have a material applied thereto which provides the strings with a tacky surface. In some forms the material can be a solution or a dry adhesive. In other forms the material can be hook-like which engages the loop-like surface of a tennis ball. As such, a tennis ball can be struck creating more RPM to impart spin to the ball.
Description
- This invention relates to improved tennis racket strings. More particularly, this invention relates to tennis racket strings which are treated to provide improved results when playing the game of tennis.
- The nature of the strings of a tennis racket is critical to one's success in the game of tennis. When striking a tennis ball the strings interact with the fibrous felt cover of the ball. Typical strings are most often made of nylon or polyester and are selected for their properties of elasticity, durability, tension retention, rebound efficiency, and the like. When striking a ball, the intention is to provide a high RPM and a spin, such as to create a slice or top spin, so as to cause problems for an opponent.
- Some attention has been given to this problem with original equipment rackets being provided, at some cost, with strings specifically designed, in profile or material, to increase the ability to provide spin. However, to date nothing has been done to solve this problem for those owning existing strung rackets.
- Thus, despite all the attention given to the nature of the strings, such attention has heretofore not been directed to improving the coefficient of friction of the strings by applying a product to the strings, so as to enhance the possibility of applying spin to the tennis ball at increased RPM.
- It is therefore an object of one aspect of the present invention to provide strings for a tennis racket that will improve the ability of a player to apply a spin, such as a slice or top spin, to the tennis ball.
- It is an object of another aspect of the invention to apply a material to the strings which increases the coefficient of friction of the strings.
- It is an object of an additional aspect of the invention to provide a tennis racket having the above-described strings.
- These and other objects of the present invention, as well as the advantages thereof over existing prior art forms, which will become apparent from the description to follow, are accomplished by the improvements hereinafter described and claimed.
- In general, a tennis racket has a frame and a plurality of strings carried by the frame. A material is applied to the strings to improve the coefficient of friction of the strings thereby improving the striking ability of the racket.
- In accordance with another aspect of the invention, a method of manufacturing tennis racket strings includes the steps of applying a material to the strings thereby increasing the coefficient of friction of the strings and improving the result of the strings engaging a tennis ball by imparting spin to the tennis ball.
- The invention also contemplates providing an apparatus to be used for a tennis racket including a plurality of strings and a material applied to the strings. The material improves the coefficient of friction of the strings thereby increasing the possibilities of imparting spin to a ball when striking the ball.
- Preferred exemplary embodiments of strings for a tennis racket according to the concepts of the present invention is shown by way of example in the accompanying drawings without attempting to show all the various forms and modifications in which the invention might be embodied, the invention being measured by the appended claims and not by the details of the specification.

-
Fig. 1 is a perspective view of a tennis racket having a material sprayed thereon to increase the coefficient of friction of the strings. -
Fig. 2 is a perspective view of a tennis racket having an alternative material carried by the strings to increase the coefficient of friction of the strings. -
Fig. 3 is an enlarged view of the encircled portion ofFig.2 . - A tennis racket made in accordance with the present invention is indicated generally by the
numeral 10 in the figure.Racket 10 includes ahandle 11 which carries aframe 12. Theframe 12 carries a plurality ofstrings 13 which are tautly stretched within theframe 12.Strings 13 can be made of a material typically used for tennis strings such as nylon, cut gut, polyester or the like. - In accordance with one aspect of the present invention,
strings 13 are provided with an outer material that improves the coefficient of the friction of the strings and effectively renders them tacky. One type of material would consist of a hydrogenated rosin such as that sold under the trademark STAYBELITE by Pinova, Inc. of Brunswick, Georgia. Such a rosin can be incorporated into a paste or a spray such as the Mueller Stickum paste or Mueller Stickum Spray Grip Enhancer sold by Mueller Sports Medicine, Inc. of Prairie du Sac, Wisconsin. - These or equivalent materials, may be applied to the strings in a number of ways. For example, with the material in a gel form, such could be provided in a tube with some type of applicator, such as a sponge, so that when the tube is squeezed, the material saturates the sponge. Alternately, a roll-on ball type mechanism could be provided. Or most simply, a towelette could be saturated with the material so that it could be rubbed onto the strings. If the material is in a liquid form, it could be provided as an aerosol spray to be applied to the strings as shown in the figure where a
cannister 14 is used to spraymaterial 15 onto the strings. Whatever the form of dispensing, such provides thestrings 13 with a tacky feeling and yet, when dried, the material will not be transferred to a tennis ball when it is struck. But when a ball is struck, the presence of the material enhances the RPM of an airborne ball increasing the possibility of imparting a desirable spin to the ball. - To even further increase the coefficient of friction of the strings and to further enhance the ability to spin the ball, the material can include a grit or other abrasive particles which provide the strings with roughness in addition to tackiness. Such a grit could simply be in the form of a sand.
- In accordance with another aspect of the invention, a dry adhesive could be applied to
strings 13. Such could use the technology of Nanograiptech of Pittsburg Pennsylvania. This adhesive could be extruded onto the strings to provide the required coefficient of friction increase. The advantage of this alternative is that there is no possibility of a residue of the product being transferred to a tennis ball. - Another aspect of the present invention is shown in
Figs. 2 and3 . In this embodiment an array of VELCRO-like micro-hooks 16 are provided to generally coat the strings. Since tennis balls are made of a felt-like material, such provides the loops to be temporarily gripped byhooks 16 to enhance the ability of the user of theracket 10 to impart spin to the tennis ball - In view of the forgoing description, it should be evident that a tennis racket and the tennis racket strings described herein accomplish the objects of the invention and substantially improve the art.
