ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to racquet stringing. More particularly, the present invention relates to a racquet and a method of stringing a racquet
BACKGROUND OF THE INVENTION
As is known, racquets, such as tennis racquets for example, include a frame having a handle extending from a ring-shaped head, and at least one resilient string strung across the head. Stringing a racquet, includes a number of steps where a stringer can make a mistake and incorrectly string the racquet. For example, the stringer normally has to identify center holes at a top and a bottom of the head of the racquet as starting points for stringing the racquet. Thereafter, as the stringing continues, vertical stringing holes and horizontal stringing holes must be differentiated. Initially, this is not very difficult. However, as the stringing moves away from the center holes, vertical holes eventually alternate with horizontal holes, thereby making the differentiating more difficult.
What is needed, therefore, is a racquet and a method of stringing a racquet wherein starting holes, vertical and horizontal holes, and tie-off holes of the racquet are clearly differentiated in order to make stringing the racquet fool-proof.
SUMMARY OF THE INVENTION
Accordingly, one object of the present invention is to provide an improved racquet and method of stringing a racquet wherein stringing the racquet is simplified.
Another object of the present invention is to provide an improved racquet and method of stringing a racquet wherein vertical and horizontal string holes of the racquet are clearly differentiated.
An additional object of the present invention is to provide an improved racquet and method of stringing a racquet wherein starting string holes are differentiated from other string holes of the racquet.
A further object of the present invention is to provide an improved racquet and method of stringing a racquet wherein tie-off string holes of the racquet are differentiated from other string holes of the racquet.
The present invention meets these and other objects by providing a racquet including a head having a multiplicity of spaced-apart string holes, and grommets fitted in the string holes. The grommets are divided into visually differentiated groups.
According to one aspect of the present invention, the groups of grommets are visually differentiated by color.
According to another aspect of the present invention, the groups of grommets are visually differentiated by shape.
The present invention also provides a racquet head guard including a head guard for wrapping around an outer surface of a racquet head, and grommets unitarily formed with the head guard for fitting within string holes of the racquet head. The grommets are divided into visually differentiated groups.
The present invention further provides a method of stringing a racquet including a head having a multiplicity of string holes divided into starter, vertical, horizontal, and tying string holes. The method includes fitting a first group of grommets into the starter string holes, fitting a second group of grommets into the vertical string holes, fitting a third group of grommets into the horizontal string holes, and fitting a fourth group of grommets into the vertical string holes. Each of the groups of grommets is visually differentiated from one another. A string is then first passed through the string holes fitted with the first group of grommets, then the string holes fitted with the second group of grommets, and then the string holes fitted with the third group of grommets. The ends of the string are finally tied off in at least one of the string holes fitted with the fourth group of grommets.
