Description

Badminton racket frame which strengthened elasticity of string {BADMINTON RACKET FRAME ENFORCING ELASTIC POWER OF STRING}

The present invention is a badminton racket frame that reinforces the elasticity of the string, more specifically, the inner part of the badminton frame to which the string is fastened to deeper configuration by increasing the power range and elasticity of the string to increase the power of the string and at the same time shuttlecock It relates to a badminton racket frame with enhanced shock absorption.

When the shuttlecock is impacted on the string fastened to the badminton frame and the badminton player kicks, the frame vibrates finely due to the impact shock caused by the shuttlecock, and the elasticity of the string interacts with the vibration. The elasticity to repel the shuttle cock is generated.

However, if only rigid materials are used to emphasize the durability of the frame, the problem is that vibration, which is the source of elastic force, does not occur constantly.On the contrary, when vibration is generated more than necessary because the frame itself is highly flexible, You'll fall into a dizzying dilemma.

In addition, when the shuttlecock is impacted, the frame is slightly twisted with fine vibration. If the distortion is made in a random direction, the vibration loss is severe and the energy consumption is increased while converting the vibration force to the elastic force of the string. Regardless of the material, its durability is also reduced.

Therefore, the material and structure of the inner periphery of the frame to which the string is connected should be made to solve both sides as much as possible.

In order to overcome the above problem, the applicant has obtained the right to the registered utility model No. 433661 with respect to the badminton racket frame which is formed with a so-called Y-shaped track.

1 is a perspective view showing the structure of the Y-shaped track of the known badminton racket frame, Figure 2 is a cross-sectional view showing a cross section of the central portion of the Y-shaped track shown in FIG.

1 and 2 show the structure of the Y-shaped track of the registered Utility Model No. 433661, specifically, the Y-shaped track 100 is widened at a predetermined portion of the upper, lower, left, and right portions of the inner circumference 70 It consists of a starting portion 110 and an extended portion 120 which has been extended in a predetermined length in the open state, and a terminating portion 130 whose width is narrowed again. The extended portion 120 extending in the open state is distinguished from the outer inner circumferential portion 70 by the stepped portions 140 formed at both sides. In addition, the surface of the portion extending in the open state is provided with a recess 150 which is configured to be recessed slightly lower than other portions.

As described above, when the inner periphery 70 of the frame 10 has a three-dimensional protrusion structure, the vibration direction is concentrated in the direction of the strings 61 and 62 according to the three-dimensional structure so that the vibration energy loss is reduced and a certain shape is obtained. Only the frame 10 is deformed to preserve the durability, in particular, the upper, lower, left, and right portions of the frame 10, where the impact occurs a lot, the need to achieve such a special purpose than other areas, and the inner circumference of the three-dimensional structure The outer direction of the part 70 is maintained in a general shape, but formed by forming the center surface to which the strings (61, 62) are connected so as to be slightly recessed inwardly with the other outer part with the help of the step (140). At the same time, the vibration is dispersed by the width and the vibration is transmitted to the outside through the boundary of the step 140 so that the vibration is concentrated only in the direction of the strings 61 and 62. It is said that the effect of reducing the impact force by impact is increased by increasing the distance the impact is transmitted if the gap is slightly indented.

That is, the Y-shaped structure of the stepped 140 according to the above technique is a structure for dispersing the impact as much as the Y-shaped while concentrating the impact in the direction of the strings 61 and 62, and the recess 150. Is described as performing a function to physically reduce the impact by increasing the distance according to the impact.

Since the Y-shaped track 100 concentrates the vibration in a certain direction, the vibration loss is less, thereby achieving a more powerful kick, and the impact of the frame 10 can be distributed without distorting the random impact. It is disclosed that the frame 10 provides properties that can ensure the durability and stability of itself.

However, if the depth due to the recess is formed deeper than the outer surface of the stepped portion, the space for fastening the string can be secured so that the distance from the impact of the shuttlecock to the frame can be increased, thereby improving the impact force according to the impact. Although it is possible to increase the effect that can be reduced, there is a limit according to the above technique to secure the length by the recess.

In addition, if the impact on the impact is concentrated only on the part where the string is fastened, there is a limit in the amount of shock absorption. Therefore, when the recess is formed in the inner direction as well as the outer direction where the string is formed based on the frame, it is more stable and strengthened. The impact amount absorbing function can be exerted, and in the above technique, since the impact amount is absorbed only in the inward direction in which the string is fastened, the overall stability of the frame is relatively low.

In addition, the above technique has a limitation in that the stepped portion is formed in an upright straight shape to concentrate the shock absorption of the shuttlecock in the recess, and thus the shape of the stepped portion needs improvement.

Therefore, by providing a structure that can sufficiently secure the indentation of the frame to strengthen the elasticity of the string and at the same time to form a recess on the inside as well as the outside to ensure the stability of the shock absorbing mechanism is formed so that the step toward the recess There is a need to present a new and advanced badminton frame structure that allows the impact to be more concentrated in the recess.

The present invention has been made to overcome the problems of the above technique, and provided with a Y-shaped track having a recessed portion formed by a step, but by expanding the Y-shaped track to the inner and outer parts of the frame, to strengthen the elastic force of the string and The main object of the badminton racket frame to ensure the durability of the frame.

Another object of the present invention is to increase the durability of the frame by forming the inner and outer side inclined surfaces of the step into a specific shape.

Another object of the present invention is to achieve a stable structure of the racket frame by treating the recess portions formed in each of the inner and outer Y-shaped tracks differently.

In order to achieve the above object, the badminton racket frame to increase the elastic force of the string according to the present invention, the start portion to start to widen in the Y-shape, and provided with a stepped on both sides in the width widened state to extend a certain length Y-shaped tracks having recesses formed between the stepped portions and recesses formed at the end portions of the recesses, the Y-shaped tracks being narrowed to Y-shaped widths at the ends of the recesses; The step may include an inner inclined surface formed to be inclined toward the recess such that the lower length of the recess is wider than the upper length of the recess, and an outer inclined surface extending to the edge of the outer portion of the frame. It is characterized by.

Further, the recessed depth of the recess formed inside the frame is deeper than the recessed depth of the recess formed outside the frame.

In addition, the outer inclined surface has a convex shape in the outward direction is characterized in that it is formed to extend curvature.

According to the badminton racket frame to increase the elastic force of the string according to the present invention,

1) Increase the power of the string and maintain the overall frame durability,

2) Increase the elasticity of the string to secure the repulsion against the shuttlecock, providing a foundation to enjoy a more powerful badminton game,

3) It has the effect of providing shock absorbing effect of more stable shuttlecock.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale and wherein like reference numerals in the various drawings refer to like elements.

Figure 3 is a perspective view showing a schematic structure of the inner Y-shaped track of the badminton racket frame with increased elastic force of the string according to the present invention, Figure 4 is an outer Y of the badminton racket frame with increased elastic force of the string according to the present invention It is a perspective view which shows schematic structure of a female track.

In addition, Figure 5 is a cross-sectional view showing the inner and outer Y-shaped track of the badminton racket frame according to the present invention.

As can be seen from Figures 3 and 4, the badminton racket according to the present invention is provided with an inner Y-shaped track (see Figure 3) at a certain portion of the inner portion of the frame, and at the same time the outer portion of the outer portion of the frame Y-shaped tracks (see Fig. 4) are provided.

The approximate structure of the inner / outer Y-shaped tracks is similar to the Y-shaped tracks of registered utility model 433661. Specifically, the inner Y-shaped tracks 100 'and the outer Y-shaped tracks 200 are located inside the frame (or outside). Of the upper and lower left and right portions of the site) starting portions (110, 210) starting to widen in a certain portion of the extension portion 120, 220 that has been extended in a predetermined length in the open state, and the end portion 130, 230 narrowing the width again The inner and outer Y-shaped tracks 100 'and 200 are formed at the same inner and outer portions of one portion of the frame. The recess 150 is provided with a plurality of through holes 50 for inserting and fixing strings.

However, the badminton racket frame according to the present invention, as the biggest difference from the registered utility model No. 433661 is that it further includes the above-mentioned outer Y-shaped track 200, and the inner and outer Y-shaped track (100 ', 200) In the frame portion formed with), the stepped structure deformed without the inner circumference extends to the inner and outer edges of the frame, and at the same time, the depth of the recess 150 is relatively deepened corresponding to the rise of the stepped height.

Hereinafter, with reference to Figure 5 will be described in detail the structure of the badminton racket frame according to the present invention.

First, the stepped 140 'is formed with an inner inclined surface and an outer inclined surface based on the tip portion, and the inner inclined surface (also referred to as the' first inclined surface ') 141 is formed from the highest portion of the stepped 140'. It is inclined narrowly toward the set 150, and the outer inclined surface (also referred to as the 'second inclined surface') 142 is inclined narrowly toward the outer portion of the frame from the highest portion of the step (140 '), but the highest It has a convexly inclined portion such as a convex lens from the portion to the outward direction. That is, the cross-sectional shape of the step 140 'generated through the inner inclined surface 141 and the outer inclined surface 142 has a structure like a mountain. The stepped 140 'is provided with one pair on both sides of the recess 150, and only the inclination angles of the inner inclined surface 141 and the outer inclined surface 142 are different from each other, and the inner Y-shaped track 100' is provided. The stepped 140 'and the stepped 240 of the outer Y-shaped track 200 both include the above-described inclined surfaces 141 and 241 and the outer inclined surfaces 142 and 242 to be a pair of both sides with respect to the recesses 150 and 250, respectively. have.

 Referring to the function and operation of the inner and outer Y-shaped track (100 ', 200) by this structure as follows.

First, the outer Y-shaped track 200 has a recess 250 between the step 241 in the outer portion of the frame, which is first of all through the recess 250 of the outer Y-shaped track 200. It is to assist in absorbing the impact of the shuttlecock in the recess 250 by increasing the elasticity by securing a little more length, specifically, the outer Y-shaped track (200) simply when the impact of the shuttlecock is diffused to the inner and outer sides of the frame The impact is concentrated only on the recess 250 to prevent an unbalanced group from going to the frame, that is, the recesses 150 and 250 are symmetrically formed on the inner and outer sides of the frame to distribute the impact of the shuttlecock to the inner and outer sides of the frame in a balanced manner. It is to play a role.

However, the depression depth b of the recess 250 of the outer Y-shaped track 200 is shorter than the summation depth a of the recess 150 of the inner Y-shaped track 100 ', which is caused by the shuttlecock. Since the direct and primary shock is transmitted to the recess 150 of the inner Y-shaped track 100 'as it is, it is possible to absorb more impact in the recess 150 of the inner Y-shaped track 100'. This is because it is more helpful to maintain the balance of the frame due to the impact. If the recess 250 of the outer Y-shaped track 200 is formed deeper, the thickness of the frame becomes too thin, and thus, the frame durability is weakened. Because it can cause.

In addition, steps 140 'and 240, which provide a fundamental structure for generating recesses 150 and 250 in the inner and outer Y-shaped tracks 100' and 200, are formed over the entire width of the frame, so that the recesses 150 and 250 are formed. The wall structure of the stepped wall 140 'and 240 over the entire width of the frame at the site where the inner and outer Y-shaped tracks 100' and 200 are installed and the frame structure thinned by the formation is prevented from being vulnerable to durability. Since the role of the support for fixing the string by the stepped thickness (140 ', 240) of the thickened by the formation is strengthened so as to maintain the elastic force retention of the string as well as plays a role of reinforcing the elastic force of the string.

In addition, the step 241 of the outer Y-shaped track 200 is formed higher than the known art (Registration Utility Model No. 433661), so that the string is formed so deep in the frame that the activity range of the string is increased to It is made to be strong in power, ie elastic holding force.

The inner inclined surfaces 141 and 241 of the stepped portions 140 'and 240 have lines inclined toward the recesses 150 and 250, and thus act as a shock guide to allow the impact of the shuttlecock to properly converge into the recesses 150 and 250. to provide. That is, when an impact is generated by the shuttle cock, the shock transmitted through the string is transmitted to the recesses 150 and 250 and propagates to the inner inclined surfaces 141 and 142 of the peripheral steps 140 'and 240, and the inner inclined surfaces 141 and 241. ) Is formed to be inclined in the direction of the recess (150, 250) to prevent the unnecessary spread of the impact to the outside of the step (140 ', 240) due to the structural characteristics and serves to absorb the shock converged into the recess (150, 250) It is.

The second inclined surfaces 142 and 242 of the stepped 140 'and 240 are formed to have a curvature in a convex shape so as to cover the entire width of the frame, and primarily extends the forming range of the stepped 140' and 240 to the frame edge. It not only maintains the durability of the 140 'and 240 and the supporting force for supporting the string, but also has the overall stability of the stepped 140' and 240 because the shape is convexly convex toward the outside. It provides a structure that can be durable even by external impact.

In summary, the inner Y-shaped track 100 ′ and the outer Y-shaped track 200 are generally symmetrical with respect to the shape having the structures of the inner inclined surfaces 141 and 241, the second inclined surfaces 142 and 242, and the recesses 150 and 250, respectively. It has a structure (not a perfect symmetry, but a shape with inner / outer slopes or recesses that is symmetrical), which pursues the stability of the frame while strengthening the elasticity of the string, converging the impact of the shuttlecock, and absorbing stable shock. It provides the property that the action can be performed.

As described so far, the configuration and operation of the badminton racket frame which increased the elastic force of the string according to the present invention have been expressed in the above description and the drawings, but this is merely an example and the idea of the present invention is limited to the above description and the drawings.
