Background

The frame of a conventional picocell racquet is made of wood and the racquet is made of an aluminum core, a foam core, a honeycomb core and a composite material, and in more conventional wood or aluminum constructions, the plates are made entirely of these materials and cut to the desired finished shape. Additional wood, aluminum or other materials are used to construct the handle to increase its circumference in order to complete the clapper. However, this process limits the weight to strength ratio, customized weight, balance, etc. Traditional clapper plates are made of solid wood, injection molded or composite fibers with honeycomb cores. However, most of the existing pitchball racket surfaces are smooth surfaces and have no friction force, so that the ball striking technique is difficult to achieve in use, even if the racket surface improved at a later stage is integrally formed with surface roughness grains, the roughness grains are worn after long-time use, and the better friction force effect cannot be generated.

The thermoplastic resin surface is pressed by a forming die with forming grains under a semi-solidification state to thermoplastic form the changing grains with different roughness on the thermoplastic resin surface, and the changing grains are solidified into solid-state changing grains by cooling, so that the friction force of the batting surface of the racket body with progressive change is effectively controlled by the changing grains, and the batting spin-cutting force and more batting times of the racket body are improved.

Detailed Description

Referring to fig. 1A to 2C, a preferred embodiment of a picocell racket structure with a surface layer having varying textures according to the present utility model is shown, however, these embodiments are merely for illustration, and the present utility model is not limited to this structure; it comprises the following steps:

a 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 is provided with a head 110 and a handle 140, a convex part 130 is formed between the head 110 and the handle 140, the head 110 is provided with two side surfaces respectively provided with a cavity 190, each cavity 190 is internally leveled and combined to accommodate a surface layer 120, a thermoplastic resin 121 is covered above the surface layer 120, and the surface of the thermoplastic resin 121 is provided with variable grains 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 this 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 2C, another embodiment of the present utility model 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 of the outer cured or semi-cured layer is adhered to the surface of the head 110 to generate variable surface textures, such as a first variable texture 150 with finer roughness, a second variable texture 160 with coarser roughness, a plurality of third variable textures 170 with orthogonal straight line staggering, a plurality of fourth variable 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, the manipulation of the surface textures or the roughness and the rigidity and the bending combination of the racket plate and the ball discharging speed, and the increase of the control residence time are in direct proportion to the rotation of the ball, in this case, the textures and the roughness of various surface layers 120 are applied in the molding process, thereby controlling the friction coefficient of the ball striking.

Referring to fig. 3A to 3C, in another embodiment of the present utility model, 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, so that 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 a new variation in texture to achieve maximum spin force while providing more shots to the player. In addition, the present utility model has the function of the replaceable surface layer 120, and also has the function of extending the life of the racket body 100, providing higher value to consumers.
