Description

Racket being improved elastic and repellent force}

The present invention relates to a racket with improved elasticity, and more particularly, an elliptical head frame, a net portion provided along an inner circumference of the head frame, a neck portion formed in the long axis direction of the head frame, and extending from the neck portion. In the racket consisting of a handle portion, the elasticity is improved racket characterized in that the diagonal grooves are formed repeatedly along the outer periphery of the head frame so that the rope extending from the net portion can be wound around the head frame.

As shown in FIG. 1, the conventional racket 100 generally has an elliptical head frame 200, a net part 300 installed through the head frame 200 along the inner circumference thereof, and the head. It consists of a neck portion 400 formed in the long axis direction of the frame 200, a handle portion 500 extending from the neck portion 400, and a lower end portion 600 provided at the end of the handle portion 500.

On the other hand, such a racket is manufactured in a suitable thickness and size suitable for a variety of racket ball games such as tennis, tennis, badminton, squash, etc. In particular, a lot of research has been conducted to improve the strength, elasticity and shock absorption.

Thus, by improving the material of the racket attempted to solve the strength, resilience, shock absorption, etc. of the racket, the situation that has not been presented the most suitable material for the characteristics of the racket so far.

In addition, the racket has a very wide price gap depending on its material, and thus, providing the best racket by improving the material will result in higher supply costs to the general public, and even if the material of the racket is improved. In recent years, there have been attempts to improve the characteristics of rackets through separate items rather than the study of expensive materials.

For example, to improve shock absorption and resilience by inserting a separate piece of high elastic sponge into the net to absorb shock or increase the resilience of the net part, such a design has been proposed. Sponge pieces were easily detached from the net part by impacts such as e-balls and were not suitable for achieving the desired purpose.

Accordingly, Korean Patent Laid-Open Publication No. 2000-36629 intends to increase the resilience and shock absorption by mounting a reaction force capable of vertical flow on the racket to double the power of the racket.

However, such a design has a structural limitation that can only be limited to tennis rackets because the reaction force device capable of vertical flow is installed, and the structure of the racket is complicated by the installation of a separate reaction force device, the cost of manufacturing Not only did it increase the cost, but the maintenance costs caused by the breakdown of some of the devices did not provide a practically practical racket.

Therefore, the present invention does not need to consider the characteristics of the material, which is the problem presented above, and can provide a racket having excellent resilience and shock absorption without installing a separate device, and is not limited to tennis rackets, and various rackets The purpose is to provide a design that can achieve the same purpose in rackets used in ball games.

The present invention is a racket consisting of an oval head frame, a net portion provided along the inner circumference of the head frame, a neck portion formed in the long axis direction of the head frame, and a handle portion extended from the neck portion in order to solve the above technical problem. In the, it is made of a configuration in which oblique grooves are formed repeatedly along the outer circumference of the head frame so that the line extending from the net portion can be wound on the head frame. In addition, the diagonal groove may be repeatedly formed to be limited to only a part of the head frame.

Here, the oblique groove is preferably formed to be round in the width direction of the head frame. In the conventional racket, a string extending from the net part is penetrated through the insertion hole of the head frame to be wound into a U-shaped structure so that tension adjustment cannot be easily performed when the string is formed on the round surface of the diagonal groove formed in the head frame. This allows the strings extending from the net to be easily stringed.

In addition, by attaching a high elastic tape to the oblique groove outer surface it is possible to further increase the string tension.

On the other hand, the racket according to the present invention can form a groove in the longitudinal direction on the outer circumferential surface of the head frame, even if the high elastic tape is attached to the outer surface of the groove can fully achieve the above object.

A more preferable embodiment of the present invention is that the cord extending from the net portion is formed by the high elastic tube in the oblique grooves of the rope formed in the hair frame portion generated by hitting the racket on the ground during tennis, tennis, badmint exercise Wear can be prevented.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

2 to 3 is an embodiment showing a racket according to the present invention, the present invention is an elliptical head frame, a net portion installed along the inner circumference of the head frame, the neck portion formed in the long axis direction of the head frame And, in the racket consisting of a handle portion extending from the neck portion, the head frame along the outer periphery of the head frame 3 so that the string 15 extending from the net portion 5 can be wound around the head frame 3 Diagonal grooves 13 are repeatedly formed so as to be rounded in the width direction of (3), and a string 15 extending from the net portion 5 is covered by the high elastic tube 19 in the diagonal grooves 13. It has a formed structure.

From this configuration, the present invention can increase the tension during stringing, thereby providing a more resilient racket, and furthermore, it is possible to continuously maintain the spacing of the string 15 intersected with the net part 5, such as tennis It is not necessary to adjust the spacing of the lines crossed by the separate net part.

4 to 5 is another embodiment of the racket according to the present invention, the present invention is an elliptical head frame, a net portion provided along the inner circumference of the head frame, a neck portion formed in the long axis direction of the head frame, In the racket consisting of a handle portion extending from the neck portion, the head frame (3) along the outer periphery of the head frame (3) so that the rope (15) extending from the net portion (5) can be wound around the head frame (3) A diagonal groove 13 is repeatedly formed so as to be rounded in the width direction thereof, and a groove 21 is formed on the outer circumferential surface of the head frame 3 in the longitudinal direction, so that a highly elastic tape 17b is formed on the outer surface of the groove 21. Is attached, and the string 15 extending from the net portion 5 is covered with a highly elastic tube 19 in the oblique groove 13.

Here, since the groove 21 is formed in the longitudinal direction on the outer circumferential surface of the head frame 3, a high elastic tape 17b is attached to the outer surface of the groove 21 so that the present invention can further increase string tension. will be.

In this way, by increasing the tension in the string, the string intersected at the net part can always maintain a constant spacing to increase the resilience, and a separate line correction work can continue the movement, it is more convenient, Furthermore, it is not necessary to consider the material of the racket and string, and it is possible to provide a racket with excellent resilience and shock absorption without installing a separate device, and it is more inexpensive to be applied to the racket used in various racket ball games It is a device that produces a remarkable effect of providing a simple and excellent racket at a cost.
