Abstract

The invention relates to a metallic tennis racket (1) having nearly the same structure as a traditional tennis racket with the exception that there is no throat on the front of a handle (2) of the tennis racket (1), and several middle main strings (11) are stretched down on a string shoulder (10) provided just on the front of the handle (2), making the string net longer than a traditional racket for hitting a ball.

Description

Background Of The Invention

Traditional metallic tennis rackets genearlly have a throat between a string net for hitting a ball and a handle, and the string net is shaped nearly oval. The space or dimension of hitting a ball directly has an effect on bouncing back a ball. But the structure of traditional tennis rackets is not suitable for a beginner, who needs to learn how to control a ball at the moment when a racket hits a ball. Tratitional tennis rackets do not have advantageous structure to assist a beginner in learing to play tennis.

Summary Of The Invention

This invention has been devised, to supply a new metallic tennis racket which takes a longer time for bouncing back a ball in hitting it than a traditional one so that a beginner can have comparatively enough time in learning technique how to control a ball when a racket hits a ball.
A new metallic tennis racket in the present invention has almost the same structure as a traditional one, but does not have a throat on a front of a handle, having several middle main strings extending down to be stretched through a string shoulder provided just on the front of the handle. Therefore, the several middle main strings are longer than those in a traditional racket, slowing down the time and speed in bouncing back a ball when the racket hits it so that a beginner can have comparatively enough time in learning the relations of the surface of the string net and a hitting angle of a ball and thus can gradually acquire technique of ball control.

Detailed Description Of The Invention

The first embodiment of an metallic tennis racket 1 in the Present invention, as shown in Fig. 1, has almost the same structure as a traditional tennis racket, except that it has no throat, having several middle main strings 11 stretched down on a string shoulder 10 provided just on a front 21 of a handle 2. The string shoulder 10 has the same width as the distance between two frame bodies at a shaft 12 for several middle main strings to be extended through thereon.
The second embodiment of an metallic tennis racket in the present invention, as shown in Fig. 2, has almost the same structure as the first embodiment with the exception that the string shoulder 210 and the front 21 of the handle 2 are formed together as a unit so as to facilitate combination of a tennis racket and production of components.
The third embodiment of an metallic tennis racket in the present invention, as shown in Fig. 3 also has almost the same structure as the first and the second embodiment but with the exception that there is no string shoulder 10 or 210, having the middle main strings are directly fixed on the front 21 of the handle 2.
From the description above mentioned and reference to Figs. 1-3, it can be understood that the main feature of the metallic tennis racket in the present invention is that the space or dimension of a string net for hitting a ball extends down to the front 21 of the handle 2, and thus the longer middle main strings 11 than those in a traditional one can slow down the speed and the time for the string net to bounce back a ball when it hits the ball. Then it may be useful for a beiginner to learn to play tennis in having comparatively enough time to comprehend relations between the string net surface and the hitting angle of a ball and techinque for controlling a ball.
Wider extension of the hitting space of the string net and omission of the throat of a traditional racket in the present invention can also economize its cost by speedy process and assemblage, as its process work only needs stretching the strings, fixing the front, the rear and the handle between the front and the rear and wrapping the outer surface of the handle with foam rubber.

Claims
