Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of badminton rackets, and particularly to a handle for a wooden badminton racket that does not require grip tape and has a sweat discharge structure.
Background Art
[0002] Badminton is a widely popular sport, and a badminton racket and a shuttlecock are tools necessary for the sport. A badminton racket generally consists of a gut, a frame, a shaft, an end cap, a handle, and other accessory members. The user grips the handle part, applies force to the handle, and swings the racket to hit the shuttlecock with the gut to play the sport.
[0003] After a long period of sports activities, a large amount of sweat may adhere to the handle part of the badminton racket. This sweat reduces the frictional force between the handle and the user's hand, increasing the possibility of the racket slipping out of the hand. In the prior art, a common method is to wrap grip tape around the handle to increase the frictional force between the hand and the handle and absorb some of the sweat to suppress the decrease in grip caused by sweat. However, when the amount of sweat is large, sweat tends to accumulate, not only making the touch slippery but also causing the sweat adhering to the handle surface not to be quickly discharged, further increasing the possibility of slippage. As a result, the comfort and stability when gripping the racket are impaired. Also, if the sweat accumulated over a long period penetrates into the handle, it may adversely affect the quality and durability of the handle material, and ultimately reduce the service life of the handle.
[0004] Note that the information described in this background art is only for the purpose of deepening the overall understanding of the background art of the present invention, and does not admit that the described content is prior art well-known to those skilled in the art, nor does it suggest so.
Summary of the Invention
[0005] The present invention aims to provide a wooden badminton racket handle that eliminates the need for grip tape and has a sweat-draining structure that allows for rapid sweat removal, maintaining the heat dissipation and dehumidification properties of the handle during use, and extending its service life. [Means for solving the problem]
[0006] To achieve the above objective, the present invention employs a wooden badminton racket handle that does not require grip tape and has a sweat-draining structure, comprising a handle body having a plurality of annular grooves and ventilation holes on its outer surface, with one end open and extending to the other end along the axial direction of the handle body to form a ventilation passage. The annular grooves are arranged sequentially along the axial direction of the handle body, and the ventilation holes are provided in the radial direction of the handle body, with both ends communicating with the groove bottom of the annular groove and the side wall of the ventilation passage, respectively.
[0007] Furthermore, the handle body comprises an integrally formed connecting portion, a gripping portion, and an enlarged diameter portion. The connecting portion is formed in a conical shape by reducing the diameter at one end on the side away from the gripping portion. The annular groove and the ventilation hole are provided in the gripping portion. The shaft diameter of the enlarged diameter portion is set to be larger than the shaft diameter of the gripping portion. The ventilation passage is located inside the gripping portion and the enlarged diameter portion.
[0008] Furthermore, a mounting hole is drilled in the conical end face of the connecting portion, extending toward the inside of the gripping portion.
[0009] Furthermore, an inclined guide surface is provided between the gripping portion and the enlarged diameter portion, and both ends of the guide surface are connected to the end face of the gripping portion and the end face of the enlarged diameter portion, respectively, via arc-shaped chamfered portions.
[0010] Furthermore, an enlarged opening is formed at the portion of the ventilation passage that is connected to the end face of the enlarged portion, and the diameter of the enlarged opening is set to be larger than the diameter of the ventilation passage.
[0011] Furthermore, the inner circumferential surface of the enlarged diameter opening is connected to the inner circumferential surface of the ventilation passage via a flat surface, an arcuate surface, or an inclined surface.
[0012] Furthermore, the annular grooves are arranged at equal intervals.
[0013] Furthermore, each of the aforementioned annular grooves is provided with corresponding 4 to 12 ventilation holes.
[0014] Furthermore, the length of the handle body is set to 15cm to 25cm.
[0015] Furthermore, the ventilation holes in each annular groove are arranged at equal intervals, and the ventilation holes in adjacent annular grooves are arranged in a staggered pattern. [Effects of the Invention]
[0016] According to this invention, by providing an annular groove and a ventilation passage in the handle body, and by providing multiple ventilation holes in the annular groove that communicate with the ventilation passage, the airflow velocity between the handle and the outside air can be increased. As a result, sweat is quickly expelled when it comes into contact with the handle, preventing sweat from remaining or accumulating on the handle surface and reducing the slipperiness of the handle surface. Consequently, the frictional force between the handle and the user's palm can be maintained, improving stability and comfort when gripping the badminton racket. Furthermore, since it is possible to prevent sweat from penetrating into the inside of the handle over a long period of time, corrosion and damage to the handle material caused by moisture can be avoided, and in turn, the service life of the handle can be extended.

[0021] Unless otherwise defined, all technical and scientific terms used in this specification shall have the same meaning as commonly understood by those skilled in the art to which the present invention pertains. Also, the terms used in this specification are for the purpose of explaining specific embodiments and are not intended to limit the present invention. Furthermore, the term "and / or" used in this specification shall include any one, or more, or all combinations of the listed related items.
[0022] As shown in FIGS. 1 to 6, a handle for a wooden badminton racket having a sweat discharge structure without a grip tape is provided with a plurality of annular grooves 2 and ventilation holes 3 on its outer peripheral surface, and includes a handle body 1 having one end opened and extending along the axial direction of the handle body 1 to the other end side to form a ventilation passage 4. The annular grooves 2 are sequentially arranged along the axial direction of the handle body 1, and the ventilation holes 3 are provided in the radial direction of the handle body 1 and are provided such that both ends communicate with the groove bottom of the annular groove 2 and the side wall of the ventilation passage 4, respectively.
[0023] According to this invention, by providing an annular groove 2 and a ventilation passage 4 in the handle body 1, and by providing a plurality of ventilation holes 3 communicating with the ventilation passage 4 within the annular groove 2, the airflow velocity between the handle and the outside air can be increased. As a result, sweat is quickly expelled when it comes into contact with the handle, preventing sweat from remaining or accumulating on the handle surface and reducing the slipperiness of the handle surface. This maintains the frictional force between the handle and the user's palm, improving stability and comfort when gripping the badminton racket. Furthermore, since it prevents sweat from penetrating into the inside of the handle over a long period of time, corrosion and damage to the handle material caused by moisture can be avoided, and consequently, the service life of the handle can be extended.
[0024] Specifically, the handle body 1 is made of wood, which has good moisture absorption and tactile properties, providing the user with a comfortable grip. The installation of the annular groove 2 not only increases the frictional force of the handle, making the grip more stable, but also ensures a path for sweat to escape, allowing sweat to flow along the annular groove 2 and be guided into the ventilation holes 3. Furthermore, the ventilation holes 3 are provided radially in the handle body 1 and communicate with the ventilation passage 4, so sweat is discharged through the ventilation holes 3 and ventilation passage 4, and at the same time contributes to heat dissipation of the handle.
[0025] Based on the above embodiment, the handle body 1 comprises an integrally formed connecting portion 11, a gripping portion 12, and an enlarged diameter portion 13. The connecting portion 11 is formed in a conical shape by reducing the diameter at one end on the side away from the gripping portion 12. The annular groove 2 and ventilation hole 3 are provided in the gripping portion 12. The shaft diameter of the enlarged diameter portion 13 is set to be larger than the shaft diameter of the gripping portion 12. The ventilation passage 4 is located inside the gripping portion 12 and the enlarged diameter portion 13. With this configuration, the handle fits the shape of the palm better, providing good support and stability, making the grip more secure and reducing operating errors due to hand slippage. Furthermore, the conical shape of the connecting portion 11 makes the connection between the gripping portion of the handle and the shaft closer and more natural, avoiding discomfort when gripping caused by the feeling of a step at the connection point between the handle and the shaft, and also contributing to improved force transmission and operating precision.
[0026] Furthermore, the material used when integrally molding the handle body 1 should preferably possess the following characteristics: a smooth surface that is resistant to splintering, a moderate specific gravity with excellent relative hardness and toughness, a surface that can be smoothly processed without the use of auxiliary agents, and excellent durability due to stable weather resistance. Boxwood is a preferred material.
[0027] Furthermore, based on the above embodiment, a mounting hole 5 is drilled in the conical end face of the connecting portion 11, extending toward the inside of the gripping portion 12. By using the mounting hole 5, the handle can be easily attached to the shaft, simplifying the installation work and improving the connection strength and stability between the handle and the shaft. In addition, future maintenance work and handle replacement will be easier, contributing to a reduction in the cost and time required for maintenance.
[0028] Based on the above embodiment, an inclined guide surface 6 is provided between the gripping portion 12 and the enlarged diameter portion 13, and both ends of the guide surface 6 are connected to the end face of the gripping portion 12 and the end face of the enlarged diameter portion 13, respectively, via arc-shaped chamfered portions. The inclined guide surface 6 fits well to the natural curve of the palm, and when gripping, the hand makes closer contact with the shape of the handle, reducing the gap between the palm and the handle and improving gripping comfort and stability. In addition, by being connected via arc-shaped chamfered portions, the transition between the gripping portion 12 and the enlarged diameter portion 13 becomes smoother, the generation of sharp corners is suppressed, pressure and friction on the hand are reduced, and the force applied to the hand is distributed, further improving gripping stability. Furthermore, by adopting a configuration consisting of an inclined guide surface 6 and arc-shaped chamfered portions, the overall appearance of the handle becomes smooth and continuous, contributing to improved design.
[0029] Based on the above embodiment, an enlarged diameter opening 7 is formed at the portion connected to the end face of the enlarged diameter portion 13 of the ventilation passage 4, and the diameter of the enlarged diameter opening 7 is set to be larger than the diameter of the ventilation passage 4. With this configuration, sweat is expelled more quickly from inside the handle through the enlarged diameter opening 7 when it is expelled, and the time it remains inside the handle is shortened, thereby improving sweating efficiency and enhancing heat dissipation performance.
[0030] Based on the above embodiment, the inner circumferential surface of the enlarged diameter opening 7 is connected to the inner circumferential surface of the ventilation passage 4 via a flat surface, an arcuate surface, or an inclined surface. This configuration makes the connection between the enlarged diameter opening 7 and the ventilation passage 4 smoother, reducing flow resistance when sweat is expelled, suppressing liquid retention, and also contributing to improved structural strength of the handle. The specific form of the smooth connection can be appropriately selected according to the usage conditions and appearance requirements, and is not particularly limited here.
[0031] Based on the above embodiment, the annular grooves 2 are arranged at equal intervals, thereby allowing sweat to flow and be discharged more uniformly along the annular grooves 2, preventing localized sweat accumulation that may occur if the spacing of the annular grooves 2 is uneven. This ensures dryness and comfort across the entire handle surface, and the pressure applied to the handle from the user's hand is distributed more evenly, reducing discomfort in gripping caused by pressure concentration, thereby improving gripping stability and comfort.
[0032] Preferably, five annular grooves 2 are arranged at equal intervals. This configuration achieves a balance between gripping comfort and sweat-wicking efficiency.
[0033] Based on the above embodiment, each annular groove 2 is provided with 4 to 12 corresponding ventilation holes 3. This configuration improves sweat drainage efficiency and heat dissipation performance, as well as making the distribution of frictional force on the handle surface more uniform, suppressing hand slippage caused by uneven frictional force, and improving gripping stability.
[0034] Preferably, each annular groove 2 is provided with seven ventilation holes 3. This configuration ensures sweat-wicking performance while preventing the handle surface structure from becoming excessively complex, thereby maintaining the structural strength and gripping comfort of the handle.
[0035] Based on the above embodiment, the length of the handle body 1 is 15 cm to 25 cm. This makes it adaptable to users with different hand sizes and contributes to efficient force transmission and ensuring operating precision.
[0036] Preferably, the length of the handle body 1 is 20.5 cm. This appropriate size ensures an ideal gripping space for many users, improving force transmission and operating precision.
[0037] Based on the above embodiment, the ventilation holes 3 in each annular groove 2 are arranged at equal intervals, thereby ensuring a uniform distribution of sweat drainage paths in each annular groove 2, and allowing sweat to flow and be discharged more uniformly along the handle surface, thus ensuring the overall dryness of the handle surface. Furthermore, the ventilation holes 3 provided in adjacent annular grooves 2 are arranged in a staggered pattern. This configuration disperses stress concentration, avoids structural weaknesses that may arise from arranging the ventilation holes 3 in a straight line, improves the structural strength and durability of the handle, and contributes to extending its service life.
