Description

Pickle racket structure

This creation is about a pickle racket structure, especially one that can achieve the effect of reducing anxiety and is convenient for users to manipulate.

Pickleball is a racket-shaped sport that combines the characteristics of badminton, tennis and billiards. The size of the Pickleball court is the same as that of a badminton court. The height of the Pickleball net is similar to that of a tennis net. The Pickleball racket used by users is like an enlarged billiard ball The ball of the pickleball is a hollow plastic ball slightly larger than a tennis ball with multiple holes, and the playing method of the pickleball is similar to that of tennis. It can be hit on the ground or directly volleyed in the air. This kind of pickle ball sport has gained a good reputation after millions of people around the world tried it in recent years. It is undoubtedly an interesting, easy-to-learn trendy sport that is suitable for all ages.

The racket core is the pillar of any pickleball racket. Among them, in order to have sufficient strength for effective hitting, the current racket core mainly adopts aluminum core or polypropylene (PP) core with a honeycomb structure; and for cushioning control and For a quieter shot, another racquet core is made of foamed polymer. However, in actual use, the racket core with a honeycomb structure tends to generate noise like drumming when the user hits the ball, and although the racket core of foamed polymer has the effect of cushioning and noise reduction, it will be damaged due to Insufficient strength requires increasing the thickness of the racket, which makes the pickleball racket appear bulky and unfavorable for operation.

In view of this, in order to provide a structure different from the conventional technology and improve the above-mentioned shortcomings, the author has accumulated many years of experience and continuous research and development, so this creation is produced.

One purpose of this invention is to provide a pickleball racket structure to solve the problems that conventional pickleball rackets tend to generate noise when the user hits the ball, or appear bulky and unfavorable for operation. And it can combine a buffer layer on both sides of a solid core board, and then combine a panel structure respectively, so as to produce sufficient hitting strength, achieve the effect of reducing noise, and reduce the overall thickness of the pickle racket for convenience. User Control.

In order to achieve the purpose of the above creation, the structure of the pickleball racket set in this creation has a reverse first panel and a second panel, the lower panel of the first panel and the upper panel of the second panel are sandwiched and glued together. Racket core; its main technical features are: the racket core includes a first buffer layer, a second buffer layer and a polymethacrylimide (Polymethacrylimide, PMI) solid core board, and the first board is combined with the lower board The first buffer layer, the upper surface of the second panel is bonded with the second buffer layer, and the polymethacrylimide solid core board is bonded between the first buffer layer and the second buffer layer.

During implementation, the first panel includes two first fiber cloths of different materials, and the two first fiber cloths are laminated and bonded to each other.

During implementation, the above two first fiber cloths are respectively a carbon fiber cloth and a glass fiber cloth.

During implementation, the second panel includes two second fiber cloths of different materials, and the two second fiber cloths are laminated and bonded to each other.

During implementation, the above-mentioned two second fiber cloths are respectively a carbon fiber cloth and a glass fiber cloth.

During implementation, the first buffer layer is a polyvinyl butyral resin (Polyvinyl Butyral Resin, PVB) film.

During implementation, the second buffer layer is a polyvinyl butyral resin (Polyvinyl Butyral Resin, PVB) film.

In order to further understand this creation, the following is a preferred embodiment, with the diagram and figure number, the specific composition and effect of this creation are described in detail as follows:

The structure of the pickleball racket of this invention has a reverse first panel and a second panel, the first panel and the second panel are respectively made of at least one fiber cloth bonded and hardened; the lower panel of the first panel and the upper panel of the second panel Clamp and glue a racket core up and down. The racket core includes a first buffer layer, a second buffer layer and a polymethacrylimide solid core board, the lower surface of the first panel is combined with the first buffer layer, the upper surface of the second panel is combined with the second buffer layer, And a polymethacrylimide (Polymethacrylimide, PMI) solid core board is bonded between the first buffer layer and the second buffer layer.

Please refer to Fig. 1, shown in Fig. 2, it is the preferred embodiment of the peak racket structure 1 of this creation, mainly comprises a first panel 2, a second panel 3, a first buffer layer 4, a second buffer layer 5 and a polymethacrylimide (Polymethacrylimide, PMI) solid core board 6. Among them, the first buffer layer 4, the second buffer layer 5 and the PMI solid core board 6 are combined to form a racket core 7, and the racket core 7 is sandwiched and bonded to the lower plate surface 21 of the first panel 2 and the bottom surface of the second panel 3. Between the upper plate surfaces 31, the first panel 2 and the second panel 3 are up and down opposite to the two ends of the racket core 7.

The first panel 2 includes two first fiber cloths (22, 23) of different materials, and the two first fiber cloths (22, 23) are respectively at least one carbon fiber cloth on the outer layer and at least one glass fiber cloth on the inner layer Fiber cloth, each carbon fiber cloth includes a plurality of woven carbon fibers, when the carbon fiber cloth is bonded and hardened with resin, the carbon fibers of the carbon fiber cloth cross each other to produce high rigidity; and each glass fiber cloth includes a plurality of woven glass fibers, when After the glass fiber cloth is bonded and hardened with resin, each glass fiber of the glass fiber cloth crosses each other to produce high toughness and strength. After the two first fiber cloths (22, 23) are stacked and bonded to each other, the lower plate surface 21 of the glass fiber cloth is combined with the first buffer layer 4, and the first buffer layer 4 is polyvinyl butyral resin (Polyvinyl Butyral Resin, PVB) film to produce cushioning and sound-absorbing effects.

The second panel 3 includes two second fiber cloths (32, 33) of different materials, and the two first fiber cloths (32, 33) are respectively at least one carbon fiber cloth on the outer layer and at least one glass fiber cloth on the inner layer Fiber cloth, each carbon fiber cloth includes a plurality of woven carbon fibers, when the carbon fiber cloth is bonded and hardened with resin, the carbon fibers of the carbon fiber cloth cross each other to produce high rigidity; and each glass fiber cloth includes a plurality of woven glass fibers, when After the glass fiber cloth is bonded and hardened with resin, each glass fiber of the glass fiber cloth crosses each other to produce high toughness and strength. After the two second fiber cloths (32, 33) are stacked and bonded to each other, the upper surface 31 of the glass fiber cloth is combined with the second buffer layer 5, and the second buffer layer 5 is polyvinyl butyral resin (Polyvinyl Butyral Resin, PVB) film to produce cushioning and sound-absorbing effects.

The PMI solid core board 6 is pasted between the lower surface 41 of the first buffer layer 4 and the upper surface 51 of the second buffer layer 5, wherein, since the material of polymethacrylimide (PMI) is based on methyl The copolymer of acrylic acid (MAA) and methacrylonitrile (MAN) is the matrix resin, which has good mechanical properties, heat distortion temperature and chemical stability, and is an ideal core material for high-performance sandwich structure composites.

In this way, when the user hits the pickle ball head-on or back-side, through the combination of two different materials of the first panel 2 or the second panel 3, sufficient rigidity and toughness can be provided for striking; The buffer layer 4 or the second buffer layer 5 can produce buffering and sound-absorbing effects; and the PMI solid core board 6 as the main core structure can generate sufficient supporting strength and reduce the thickness of the core material.
