NETTING FRAMEWORK OF A FIBER-MADE RACKET
The netting structure of a fiber-made racket comprises a racket frame and several supporting parts. The racket frame is formed with upper and lower racket frames made of the fibrous material, and internal and external penetration netting areas are formed around between the upper and lower racket frames. Several supporting parts are provided in the netting area, a couple of parts adjacent to each other are lengthways stationary in the netting area of racket, and the threads of the racket pass through the couple of supporting parts and cross vertically and horizontally in the racket frame to form a hit area. Thanks to the interval of distance of thread passing between the netting area and the supporting parts, it is easy and fast to pass the threads, reducing the area of net threads contacting with the racket frames to increase the flexibility of hit area at the time of hitting.

Consequently, because of the technical defects of described above, the applicant keeps on carving unflaggingly through wholehearted experience and research to develop the present invention, which can effectively improve the defects described above.
SUMMARY OF THE INVENTIONIn this invention, the netting structure of a racket made of a fibrous material is provided, comprising a racket frame and a supporting part. The racket frame is integrally formed with upper and lower racket frames that are made of the fibrous material, and internal and external penetration netting areas are integrally formed around between the upper and lower racket frames. Several supporting parts are provided in the netting area, a couple of parts that are adjacent to each other are lengthways stationary in the netting area of racket, and thus the threads of the racket pass through the couple of supporting parts and cross vertically and horizontally in the racket frame to form a hit area. With the netting areas of racket frame and the supporting parts between the areas, it is easy to pass the threads at a higher speed. The net threads pass through the supporting part to reduce the area of contact with the racket frame and thus relatively increase the flexibility of hit area of the racket when hitting a ball.
Now, the present invention will be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of preferred embodiments of this invention are presented herein for purpose of illustration and description only; it is not intended to be exhaustive or to be limited to the precise form disclosed.
With reference to
The racket frame 10 is integrally formed with oval upper and lower racket frames 11 and 12 that are made of the fibrous material and stretches downwards separately to two sides to bring to an end and form a grasp portion 13, and internal and external penetration netting areas 14 are integrally formed around between the upper and lower racket frames 11 and 12.
The supporting part 20 may be made of a metal, an aluminum metal or a composite material, or a fibrous material. In the embodiment, a cylindrical rod is made of a fibrous material, of which upper and lower ends that are properly long are separately stationary integrally on annular sides where the upper racket frame 11 is opposite to the lower racket frame 12, and a couple of parts that are arranged adjacent to each other are lengthways stationary in the netting area 14 of racket frame 10, and thus the net threads 30 of the racket pass through the couple of supporting parts 20 and cross vertically and horizontally in the racket frame 10 to form a hit area 31.

In order to further make apparent the structural features, applied skill and manners, and expected effects according to this invention, what are applied in this invention are in detail described, and it is thus believed that this invention is thoroughly and concretely apparent, as described below.
The racket frame 10 that is made of the fibrous material is placed in a formed molding tool (not shown), the supporting parts 20 are separately placed in a mold cavity of a predetermined netting area 14 in the formed molding tool (not shown) and are molded, and the fibrous material in the formed molding tool (not shown) is processed in a manner of air blowing. Meanwhile, the molding tool is heated, and thus after the fibrous material is solidified, the upper and lower ends of the supporting part 20 that are properly long are separately stationary on annular sides where the upper racket frame 11 is opposite to the lower racket frame 12, thereby an all-in-one structure being achieved. At the time of thread wearing, a couple of supporting parts 20 that are arranged adjacent to each other are lengthways stationary around in the netting area 14 of racket frame, so the net threads 30 passing through the couple of supporting parts 20 adjacent to each other pass and cross vertically and horizontally in the racket frame 10 to form the hit area 31. Thus, thanks to the interval of distance of thread passing between the netting area 14 and the supporting parts 20, it is smooth to pass the threads.

Here, the features and attainable expected effects of this invention are described again below:
-
- 1. The racket frame and supporting parts according to this invention may be integrally or separately formed for achievement of the stable structure, and the racket frame is formed with a permeable netting area to reduce the total weight of racket for relative achievement of an better effect of hitting.
- 2. With the intervals of distance that are formed between the netting area of racket and the supporting parts, it is smooth to pass the threads.
- 3. The net thread according to this invention contacts only the supporting parts between the racket frames, which reduces the area of contact with the racket frames to increase the flexibility of hit area at the time of hitting; further, the supporting parts are made of the composite material to damp the vibration.
- 4. The ornament strip is provided in the netting area of the racket frame according to this invention, and the advertisement typeface character or pattern blueprint may be printed on a surface of the ornament strip for achievement of the manner of advertisement.
While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
