Detailed Description
Referring to fig. 1A to 2C, preferred embodiments of the picocell racquet structure with varying surface layers are shown, but these embodiments are for illustration only and are not limited by the structure in the present application; the invention relates to a picocell racket structure with a surface layer of variable texture, which comprises:
The racket body 100 is made of carbon fiber material, as shown in fig. 2C, a thermosetting resin K is formed in the racket body 100 by thermosetting, the racket body 100 has a head 110 and a handle 140, a protrusion 130 is formed between the head 110 and the handle 140, the head 110 has two side surfaces, each of the two side surfaces has a cavity 190, a surface layer 120 is accommodated in each cavity 190 in a flattened combination manner, a thermoplastic resin 121 is coated on the surface layer 120, and the surface of the thermoplastic resin 121 has variation lines 122 with different roughness. Wherein the surface layer 120 may be in the form of carbon fiber or fiberglass cloth. The surface layer 120 of the racket body in the present embodiment has staggered variation lines with different roughness, wherein the variation lines include a first variation line 150 with finer roughness and a second variation line 160 with coarser roughness.
Referring to fig. 2A to fig. 2C, another embodiment of the present invention is shown, in which each surface layer 120 on two side surfaces of the racket body 100 has a varying pattern with different roughness, wherein the varying pattern on one surface layer includes a plurality of third varying patterns 170 with orthogonal straight line interlacing, and the varying pattern on the other surface layer includes a plurality of fourth varying patterns 180 with oblique line interlacing. In the molding process of the racket body 100, the surface layer 120 with the outer solidified or semi-solidified layer is adhered to the surface of the head 110 to generate variable surface textures, such as a first variation texture 150 with finer roughness, a second variation texture 160 with coarser roughness, a plurality of third variation textures 170 with orthogonal straight line staggering, and a plurality of fourth variation textures 180 with oblique line staggering, so as to achieve the ball striking friction degree of the racket surface and the friction coefficient between the ball and the racket surface. Manipulation of the surface texture or roughness and the stiffness and bending combination of the clapper and ball play speed, increasing control dwell time are proportional to ball spin, in which case the various surface layer 120 textures and roughness are applied during the forming process to control the coefficient of friction of the ball.
Referring to fig. 3A to 3C, in another embodiment of the present invention, three kinds of variation lines with different roughness are formed on the same plane and arranged in a top-to-bottom manner on the surface of the surface layer 120, such that the three kinds of variation lines with different roughness are respectively defined as a fifth variation line 171 with coarser roughness, a sixth variation line 172 with finer roughness, and a seventh variation line 173 with smoother roughness; the other surface layer 120 may have two kinds of variation lines with different roughness formed on the same plane and arranged in inner and outer regions, and the two kinds of variation lines with different roughness are respectively defined as an eighth variation line 181 with coarser roughness and a ninth variation line 182 with finer roughness. An advantage of applying the textured surface layer 120 is that the worn away textured surface layer 120 can be removed and replaced with a new textured surface layer 120 without having to replace the entire racket body 100. Another advantage is that a different textured surface layer 120 may be applied to each side of the racquet body 100 panel, with the new varying textures helping to achieve maximum spin force while providing more shots to the player. In addition, the present invention has the function of the replaceable surface layer 120, and also has the effect of extending the life of the racket body 100, providing higher value to consumers.
