Description

Technical Field

[0001] This application relates to the construction of a badminton racket, and more particularly to a grip construction for a badminton racket. Background Technology

[0002] A badminton racket consists of three main parts: the head frame, the shaft, and the grip. The head frame is strung to form the hitting surface, and it connects to the grip via the shaft. Traditional badminton racket grips are usually made of strong, durable wood. Factors considered in choosing wood for the grip include its availability, ease of processing, and low cost. Wood also has good damping properties, helping to absorb vibrations generated when the racket hits the shuttlecock.

[0003] Racket vibration is related to many factors, one of which is the grip. Victor Sports Co., Ltd., a well-known manufacturer, has launched a technology called Free Core, which has been granted a Taiwanese invention patent (publication number I673088). This patented technology replaces the traditional wood grip material with nano-nylon material, and the internal structure of the grip consists of a suspended hollow tube and an X-rib support structure, thereby increasing shock absorption.

[0004] For users accustomed to traditional wooden grips, while the aforementioned patented floating grip significantly reduces vibrations during impact, it also greatly reduces the feedback from the grip, thus affecting their control over power during impacts. As a result, opinions on the floating grip vary. Therefore, achieving a balance between shock absorption and providing sufficient feedback remains a challenge. Utility Model Content

[0005] The technical problem to be solved by this application is a preferred embodiment of the grip structure of a badminton racket, comprising: a main body, a front sleeve, and a rear end cap; the front sleeve is a front conical portion assembled to the front section of the main body, and the rear end cap is assembled to the rear end of the main body; wherein the main body is a hollow tubular body and is integrally formed by injection molding technology, the interior of the main body has an inner cavity and a central tube channel, the central tube channel extends from the front end of the main body along the axis of the main body to the rear end of the main body, the inner cavity and the central tube channel are connected end to end along the axial direction of the main body and penetrate the axial direction of the main body, and the central tube channel is located in the main body. The front section of the main body has an inner cavity located in the middle-rear section. The central tube channel is used to insert and fix a badminton racket's central tube to the main body. The inner diameter of the inner cavity is larger than the inner diameter of the central tube channel. The front end of the central tube channel extends towards the front end of the main body to form a connecting tube that extends beyond the front end of the front cone. The end of the central tube channel extends towards the inner cavity to form a tubular extension tube. The inner diameter of the extension tube is the same as the inner diameter of the central tube channel, allowing the central tube to be inserted. There is a gap between the outer wall of the extension tube and the inner wall of the inner cavity. A shock-absorbing bushing is fitted on the outside of the extension tube, and the shock-absorbing bushing tightly fills the gap.

[0006] The shock-absorbing bushings are made of rubber or silicone.

[0007] As a preferred embodiment of the grip structure of the badminton racket of this application, the inner wall of the tube channel has a plurality of first ribs protruding toward the center. These first ribs are evenly distributed at the circumferential positions of the inner wall of the tube channel. These first ribs extend along the axial direction parallel to the tube channel and are used to clamp the tube.

[0008] As a preferred embodiment of the grip structure of the badminton racket of this application, it includes a reinforcing tube and a connecting tube. The front end of the middle tube channel extends toward the front end of the main body to form a connecting tube that extends beyond the front end of the front cone. The reinforcing tube is a tubular component. The reinforcing tube is constructed to include a front section tube, a middle section tube, and a tail section tube located at different positions on the same axis. The middle section tube is located between the front section tube and the tail section tube. The reinforcing tube is disposed between the front cone and the front sleeve. The reinforcing tube and the middle tube channel are connected and communicate with each other in a coaxial relationship. The front cone has a fitting groove surrounding the periphery of the connecting tube. The fitting groove extends from the front cone along the axial direction toward the tail end of the main body. The tail section tube is inserted into the fitting groove in a tight fit relationship. The front section tube extends out of the front sleeve. The middle section tube is sleeved on the connecting tube and is located between the connecting tube and the front sleeve. The outer contour shape of the middle section tube matches the inner sidewall of the front sleeve, so that the middle section tube is tightly fixed between the front sleeve and the front cone.

[0009] In a preferred embodiment of the grip structure of the badminton racket of this application, the inner wall of the front section tube has a plurality of second ribs protruding toward the center. These second ribs are evenly distributed at the circumferentially divided positions of the inner wall of the front section tube. These second ribs extend along the axial direction parallel to the front section tube and are used to clamp the middle tube.

[0010] The advantages and functions of the vibration-damping grip structure of the badminton racket in this application are as follows: the main body is a component integrally molded using injection molding technology, and the main body and the middle tube channel are an integral component. When hitting the shuttlecock, the external force from the middle tube can be directly transmitted to the main body, providing the user with a solid feedback. The inner cavity and the shock-absorbing bushing can work together to provide the function of suppressing and reducing vibration. On the other hand, the reinforcing tube can further fix the middle tube to the main body, thereby directly transmitting the feedback to the main body when hitting the shuttlecock.

Detailed Implementation

[0023] In the embodiments described below, the positional relationships include: up, down, left, and right. Unless otherwise specified, they are all based on the direction shown by the components in the diagram.

[0024] Please refer to the following first. Figures 1 to 3 The diagram illustrates a preferred embodiment of the present application, including a front view, an exploded view, and a cross-sectional view. A preferred embodiment of the grip structure of the badminton racket of the present application includes: a main body 10, a front sleeve 20, a rear end cap 30, and a shock-absorbing bushing 40.

[0025] The front sleeve 20 is a front conical portion 11 assembled on the front section of the main body 10. In a preferred embodiment, the front conical portion 11 of the main body 10 has a fitting groove 110, which extends axially from the front conical portion 11 towards the rear end of the main body 10. A sleeve 21 is provided inside the front sleeve 20, which can be inserted into the fitting groove 110, and the front sleeve 20 is glued to the front conical portion 11 using adhesive. The rear end cap 30 is assembled on the rear end of the main body 10. The front conical portion 11 of the main body 10 is conical in shape, and the front sleeve 20 is also a matching conical shape that can be fitted onto the front conical portion 11 of the main body 10. The main body 10 is preferably a hollow tubular body, and the cross-sectional outline of the main body 10 is an irregular octagon (see...). Figure 5 The main body 10 is a component integrally formed by injection molding technology. The interior of the main body has an inner cavity 12 and a central tube channel 13. The central tube channel 13 extends from the front end of the main body 10 along the axis of the main body 10 to the rear end of the main body 10. The inner cavity 12 and the central tube channel 13 are connected end to end along the axis of the main body 10 and pass through the axis of the main body 10.

[0026] Preferably, the central tube channel 13 is located at the front end of the main body 10, and the inner cavity 12 is located at the middle and rear end of the main body 10. In a preferred embodiment, the length of the central tube channel 13, measured from the front end of the main body 10, is approximately 30%-40% of the total length of the main body 10.

[0027] The shaft channel 13 is used to insert and fix the shaft of the badminton racket to the main body 10. In a preferred embodiment, the cross-sectional shape of the inner cavity 12 is circular. The inner diameter D1 of the inner cavity 12 is larger than the inner diameter D2 of the shaft channel 13. The end of the shaft channel 13 (the end closest to the inner cavity 12) extends toward the inner cavity 12 to form a tubular extension tube 14. The inner diameter of the extension tube 14 is the same as the inner diameter D2 of the shaft channel 13, allowing the shaft to be inserted. A gap G exists between the outer wall of the extension tube 14 and the inner wall of the inner cavity 12 (see...). Figure 4 ).

[0028] The main body 10 is equipped with a shock-absorbing bushing 40, which is fitted over the extension tube 14 and tightly fills the gap G. The shock-absorbing bushing 40 is preferably made of rubber or silicone to absorb vibration. Since the main body 10 is a component integrally molded using injection molding technology, the main body 10 and the middle tube channel 13 are integral components. When the ball is hit, the external force from the middle tube can be directly transmitted to the main body 10, providing the user with a solid feedback. The inner cavity 12 and the shock-absorbing bushing 40 can work together to provide the function of suppressing and reducing vibration.

[0029] In a preferred embodiment, the inner wall of the central tube channel 13 has a plurality of first ribs 15 protruding toward the center. In a preferred embodiment, there are a total of 6 first ribs 15, which are evenly distributed at the circumferential positions of the inner wall of the central tube channel 13. The first ribs 15 extend along the axial direction parallel to the central tube channel 13. The first ribs 15 are used to clamp the central tube. The function of the first ribs 15 is to increase the tightness of the combination with the central tube and reduce the vibration transmitted to the main body 10 when the central tube is subjected to force.

[0030] Please see Figures 6 to 8 Another preferred embodiment of the grip structure of the badminton racket in this application, and Figures 1 to 5The illustrated embodiment differs in that it further includes a reinforcing tube 50 and a connecting tube 16. The front end of the central tube channel 13 extends toward the front end of the main body 10 to form a connecting tube 16 extending beyond the front end of the front cone 11. The reinforcing tube 50 is a tubular assembly, comprising a front section tube 51, a middle section tube 52, and a tail section tube 53 located at different positions on the same axis, with the middle section tube 52 situated between the front section tube 51 and the tail section tube 53. The reinforcing tube 50 is disposed between the front cone 11 and the front sleeve 20 of the main body 10. The reinforcing tube 50 and the central tube channel 13 are coaxially connected and communicate with each other. A fitting groove 110 surrounds the periphery of the connecting tube 16 and extends axially from the front cone 11 of the main body 10 toward the tail end of the main body 10. Please refer to [link to previous section]. Figure 8 Preferably, the opening of the fitting groove 110 gradually narrows, forming a tapered fitting groove 110. The tail section 53 of the reinforcing tube 50 is inserted into the fitting groove 110 in a tight fit. The front section 51 passes through the sleeve 21 inside the front sleeve 20 and extends forward out of the front sleeve 20. The middle section 52 is sleeved on the connecting tube 16 and is located between the connecting tube 16 and the front sleeve 20 (see...). Figure 8 The outer contour shape of the middle tube 52 matches the inner wall of the front sleeve 20. The inner sleeve 21 of the front sleeve 20 abuts against the middle tube 52, so that the middle tube 52 is tightly fixed between the front sleeve 20 and the front cone 11 of the main body 10, thereby directly transmitting the feedback to the main body 10 when hitting the ball.

[0031] In a preferred embodiment, the inner wall of the front tube 51 has a plurality of second ribs 511 protruding toward the center. In a preferred embodiment, there are a total of 6 second ribs 511, which are evenly distributed at the circumferential positions of the inner wall of the front tube 51. The second ribs 511 extend along the axial direction parallel to the front tube 51. The second ribs 511 are used to clamp the middle tube. The second ribs 511 can work with the first ribs 15 to reduce the vibration transmitted to the main body 10 when the middle tube is under force, and can directly transmit the feedback to the main body 10 when hitting the ball. In a preferred embodiment, the middle tube of the badminton racket can be fixed to the middle tube channel 13 and the reinforcing tube 50 with adhesive.

[0032] The embodiments and / or implementation methods described above are merely preferred embodiments and / or implementation methods for implementing the technology of this application, and are not intended to limit the implementation methods of the technology of this application in any way. Any person skilled in the art may make some modifications or alterations to other equivalent embodiments without departing from the scope of the technical means disclosed in this application, but these should still be regarded as the technology or embodiments that are substantially the same as those of this application.
