Description

Pickleball racket structure capable of controlling the time the ball stays on the racket surface when hitting the ball and its manufacturing method

The invention relates to a racket body formed by hot pressing and an elastic throat formed at a predetermined position of the racket body. The racket body has a racket surface made of carbon fiber. The inside of the racket body is pressurized and filled with a thermosetting resin. Structural designers who can effectively control the shape changes of the length, width and depth of the elastic throat of the racket body in order to increase the local strength, local bending moment and local torsion moment of the racket body.

Press, the frame of a traditional sports racket is made of wood, while the racket is made of aluminum core, foam core, honeycomb core and composite materials. In a more traditional wooden or aluminum structure, the racket board is entirely made of these materials. , and cut into the desired finished shape. To complete the clapper, additional wood, aluminum or other materials are used to build the handle to increase its girth. However, this process will limit the weight-to-strength ratio and customized weight, balance, etc. Traditional clapperboards are made from solid wood, injection molding, or composite fiber with a honeycomb core. All these racket structures have shortcomings due to limitations in manufacturing methods, materials and technology. Today's racquets rely on these homogeneous structures that limit weight placement and overall weight, limiting their effectiveness and benefits. In addition, rackets with improved honeycomb cores will also be limited by the cutting method of the panels, causing the edges of the core to be exposed in the gap between the top and bottom surfaces. Because this gap can easily damage the clapper, a plastic cover is often added around the edge, creating a step around the edge, resulting in an uneven hitting surface. If the ball is hit near the edge, it will change its direction. Another problem with conventional rackets is the grip, which is made of The surface is made of different materials stacked up, so additional processing is required, and the assembly of each component cannot produce a beautiful appearance. Another problem with solid sports racket construction is the sound produced when the ball is struck. The core is usually made of a completely rigid material that makes a loud noise when struck, without the addition of a core or other damping material due to weight restrictions or manufacturing difficulties. Solid hitting areas are usually made of wood and aluminum alloy materials. Because these structures are easy to manufacture, solid wood or aluminum structures have been used to produce low-priced, low-tech, and mass-produced rackets. But these solid structures come with a number of limitations, primarily the materials from which they are made. The frame and solid structure cannot be manipulated to increase strength, stiffness or change the shape of the structure.

Therefore, in view of the problems existing in the above-mentioned conventional structures, how to develop an innovative structure that is more ideal and practical and can meet the ardent expectations of consumers is also the goal and direction that relevant industries must work hard to develop and break through; in view of this , the creator has many years of experience in the manufacturing, development and design of related products. After detailed design and careful evaluation based on the above goals, he finally arrived at a truly practical invention.

That is, the main purpose of the present invention is to provide a pickleball racket structure that can control the time the ball stays on the racket surface in the hitting state; the problem it intends to solve is that the conventional structure has many limitations, mainly: The materials for manufacturing these structures will be limited, and the problem of being unable to control the racket structure to increase strength, stiffness or change the shape of the structure is overcome; the present invention mainly consists of: a racket body, having a head and a grip The handle has two side surfaces respectively defined as a first racket surface and a second racket surface.

Please refer to Figures 1A to 1B, which are preferred embodiments of the pickleball racket structure of the present invention that can control the time the ball stays on the racket surface when hitting the ball. However, these embodiments are for illustration only and are not disclosed in the patent. The application is not limited by this structure; it includes: a racket body 100 with a head 150 and a handle 130. The head 150 has two side surfaces respectively defined as a first racket surface 170 and a first racket surface 170. Two racket surfaces 200. The first racket surface 170 has a hitting surface 120. An elastic throat 110 is provided between the head 150 and the handle 130. The elastic throat 110 can increase or decrease the predetermined sphere and the third. The residence time between the racket surfaces 170 also enables the racket body 100 to have more hitting power, control the hitting spin and sports durability. The elastic throat 110 may have an opening 160 penetrating corresponding to the relative surface positions of the first racket surface 170 and the second racket surface 200. The opening One side 190 is provided on both sides of the 160. Each side 190 is provided with a slot 180 corresponding to the bottom edge. The handle 130 is provided with two connecting tubular members relative to the first racket surface 170 and the second racket surface 200. 140. The connecting tubular member 140 can be formed into different diameters, shapes and lengths to generate the required elasticity and moment to manage the residence time when the ball impacts the racket. Compared with the conventional structure of using a honeycomb cutting structure to manufacture a pickleball racket, it is not feasible to manufacture a molded racket with the conventional structure because the honeycomb structure of the conventional structure is not strong enough. The present invention can include honeycomb surfaces or fibers through the elastic throat 110 The rib structure is such that the stringing surface of the racket body 100 connects the head 150 of the racket body 100 to the handle 130 through a pair of connecting tubular surfaces 140 . Similarly, when manufacturing the elastic throat 110 and achieving improved bending and torsion enhancement, the opening 160 can be formed along the center line of the elastic throat 110 close to the racket body 100 on the same plane as the first racket surface 170. The opening 160 160 can form a more flexible elastic stretch area of the elastic throat 110 to increase elasticity and torsion, improve dwell time, and thereby improve control and rotation.

Please refer to Figures 2A-2B, which is another embodiment of the present invention, in which the elastic throat 220 can be a modified structure with a recessed area corresponding to the relative surface positions of the racket surfaces 170a on both sides. This embodiment includes a reduced thickness elastic throat 220 located in the same plane as the racket face 170a of the racket body 210. This structure is on the same plane as the racket surface 170a of the racket body 210, and/or the transition area 230 including the grip 130 perpendicular to the racket surface 170a of the racket body 210 will be narrowed. Therefore, creating a narrower transition area 230 will increase the elasticity of the elastic throat 220 and therefore allow the racket body 210 to absorb some of the ball's energy to improve stay and thereby improve control. In order to create a stronger or stiffer racket body 210, we can increase the thickness of the elastic throat 220 along the plane of the ball face 170a to minimize the overall elasticity of the racket body 210 and therefore make more The energy given to the pickleball ball produces greater hitting power.

Please refer to Figures 3A~3B, which is another embodiment of the present invention, in which the elasticity The throat 250 may be in a concave shape corresponding to the position of the racket surface 170b relative to the side. This implementation includes: the thickness reduced from the elastic throat 250 of the vertical racket to the racket surface 170b of the racket body 240. The reduction or thinner portion of the elastic throat 250 will help to create a spring effect near the grip 130b and the elastic throat 250 to increase the elasticity of the racket face 170b in the hitting direction. Curving the racket surface 170b in the direction of hitting the ball increases the residence time of the ball on the racket surface 170b. Therefore, the residence time of the ball on the racket surface 170b can be increased. The time the ball stays on the racket surface 170b will help to improve control. direction of the ball and create more significant spin. For example, in Figure 3B, the elastic throat 250 can be covered with a rubber sleeve 250a. In addition to increasing the local buffering force, the surface of the rubber sleeve 250a can also be printed with totems or text marks.

Please refer to Figure 4, which is another embodiment of the present invention, in which the elastic throat 300c can be designed as a change in the form of a separate component, so that the racket body 270 is separated from the elastic throat 300c into a first A racket 280 and a second racket 290. The first racket 280 is provided with a connecting portion 300b at one end. The second racket 290 is provided with a groove 300a corresponding to the connecting portion 300b. The inside of the groove 300a is covered with A layer of rubber film layer 310 is used to make the connecting part 300b butt and glue the fixing groove 300a. The elastic throat 300c generates a local elastic buffering force through the rubber film layer 310. In this design, the thickness, stiffness and type of ductile material can be varied to achieve different bending dimensions. Another advantage of the two separate racket parts is that vibration-absorbing materials can be used to suppress the vibration frequency when the ball hits the ball.

Please refer to Figures 5A-5B, which is another embodiment of the present invention, in which the elastic throat 340 can be L-shaped and narrow corresponding to the relative side positions of the first racket surface 170d and the second racket surface 200d. The elastic throat 340 has a slit shape, so that the elastic throat 340 includes a transverse open groove 330 and a longitudinal groove 370 connected to the other end of the open groove 330. One end of the open groove 330 is open corresponding to the first racket surface 170d, and the third The second racket surface 200d is closed and defined as a continuous portion 360 corresponding to the elastic throat 340, so that a polyurethane film 380 is embedded in the longitudinal groove 370, and the elastic throat 340 generates a local elastic buffer through the polyurethane film 380. force.

Please refer to Figures 6A-6B, which is another embodiment of the present invention, in which the elastic throat 440 can be in an I-shaped narrow position corresponding to the first racket surface 170e and the second racket surface 200e relative to the side. The elastic throat 440 has a slit shape such that the elastic throat 440 includes a slit 410 and a side through hole 420 extending from both ends of the slit 410. The elastic throat 440 generates a local elastic buffering force through the slit 410 to accumulate After the energy is released, the attack will be carried out. This combination of the slit 410 and the side through-hole 420 helps to make the racket body 400 more elastic and flexible when hitting the ball. The transition area 430 in the first racquet face 170e and the elastic throat 440 of the grip 130e may improve ball residence time and therefore improve control and spin.
