The present application relates to a cover for forming a swing exerciser and a cover set including the same.

First, a cover for forming a swing exerciser (hereinafter referred to as 'this cover') 1 according to an embodiment of the present application will be described.

Figure 1 is a schematic front view of a cover for forming a swing exerciser according to an embodiment of the present application mounted on a racquet head, Figure 2 is a schematic perspective view of a cover for forming a swing exerciser according to an embodiment of the present application, Figure 3 is A schematic front view of a cover for forming a swing exerciser according to an embodiment of the present invention including a first part and a second part mounted on a racquet head, and FIG. 4 is a first part and a second part mounted upside down on a racquet head. It is a schematic front view of the cover for forming a swing exerciser according to an embodiment of the present invention including

Referring to FIG. 1 , the present cover 1 includes a main body 11 arranged to surround a part (first part) of the racquet head 9 in the circumferential direction of the racquet head 9 . In other words, the cover 1 may be disposed while covering a portion of the racquet head 9 except for the other portion (second portion) in the circumferential direction of the racquet head 9 . For example, the cover 1 may be disposed while covering the middle portion 93 of the racquet head 9 except for the upper portion 91 and the lower portion 92 in the circumferential direction of the racquet head 9 .

For example, referring to FIG. 2 , the body portion 11 may have a through hole 111 formed in a vertical direction. Accordingly, the cover 1 can be mounted on the racquet head 9 by inserting the racquet head 9 into the through-hole 111 of the main body 11 . In order for the cover 1 to be disposed while covering a part of the racket head 9 except for another part, the maximum length (length) of the body part 11 in the vertical direction is the net part 91 of the racket head 9 ) may be smaller than the maximum length in the vertical direction. Accordingly, the cover 1 may be mounted on the racquet head 9 so as to cover a part of the net portion 91 of the racquet head 9 and expose another part.

In addition, the length of the body portion 11 in the width direction (2 o'clock to 8 o'clock direction, see FIG. 2) may be smaller than the maximum length of the racket head 9 in the width direction (3 o'clock to 9 o'clock direction, see FIG. 1). there is.

In addition, the body portion 11 may be made of a fabric that allows ventilation. In addition, the body portion 11 may be made of a material having elasticity. Accordingly, the body portion 11 can be stretched (elastically deformed) when the racket head 9 is inserted into the through hole 111 when the cover 1 is attached to the racket head 9, The head 9 can be inserted into the through-hole 111, and the main body 11 is stretched in a state where the cover 1 is mounted on the racquet head 9 by the elastic restoring force of the body 11. It may not be detached from the racquet head 9 while it is in place, and when the cover 1 is detached from the racquet head 9 (unmounted state), it contracts (restores elasticity) and returns to its original state.

Also, the body portion 11 has an air permeability lower than that of the net portion 94 of the racquet head 9. Accordingly, when a swing is made with the cover 1 attached to the racquet head 9, the air resistance can be increased compared to the case where the cover 1 is not attached, and the increased air resistance allows swing practice ( muscle strengthening, posture correction, etc.) can be made.

The body portion 11 may be a fabric having elasticity, and various conventional fabrics meeting these conditions may be applied to the body portion 11 .

In addition, the main body portion 11 is made of fabric, but a separate hole may not be processed. Accordingly, ventilation by a separate hole may not occur in addition to ventilation made due to the nature of the fabric. If a separate hole is machined in the body part 11, air passes through the hole without air resistance, but in the part where the hole is not formed, it is difficult for air to pass through compared to the hole, so a vortex phenomenon may occur , The airflow resistance value is different for each part, and the difference in airflow resistance may cause the racket to shake during swing practice.

On the other hand, according to the present cover 1, since no separate hole processing is made in the main body 11, the cover 1 has small holes uniformly distributed throughout the cover 1 due to the nature of the fabric, thereby circulating air and resistance value. This can always be kept constant, and accordingly, in the part where the air permeability of the cover 1 is the same during swing, the resistance of the air acts constantly, so that swing practice in the correct posture can be achieved, and the unbalance absorption function The strain on the wrist can be minimized.

Also, referring to FIG. 3 , the body portion 11 may include a first portion 113 having a first air permeability and a second portion 112 having a second air permeability greater than the first air permeability. . In other words, the air resistance of the second portion 112 may be smaller than that of the first portion 113 . For example, the air resistance of the first portion 113 may be 60, and the air resistance of the second portion 112 may be 80. In addition, each of the first part 113 and the second part 112 may have a uniform air permeability (equal value) in the circumferential direction of the racquet head 9 . Accordingly, in the body portion 11, air transmittance of the same value may be uniformly formed in regions having the same air transmittance.

Since the body part 11 includes the first part 113 and the second part 112 having different degrees of air resistance, an impact can be accurately captured.

For example, the first part 113 may be formed on the upper side of the second part 112 .

Also, the area of the first portion 113 may be larger than that of the second portion 112 . Also, the minimum length of the first portion 113 in the vertical direction may be greater than the maximum length of the second portion 112 in the vertical direction. In addition, referring to FIGS. 3 and 4 together, the first part 113 is positioned below the second part 112 so that the cover 1 can be mounted on the racquet head 9, the body part 11 ) may have a symmetrical shape around a line crossing the middle of the body portion 11 in the vertical direction in the width direction.

Accordingly, when comparing FIGS. 3 and 4, the cover 1 can be mounted on the racquet head 9 by being turned over so that the first part 113 is positioned lower than the second part 112. Depending on whether the first part 113 is positioned above or below the second part 11, the swing weight may vary.

For example, when the first part 113 is positioned above the second part 112 (see FIG. 3) and when the first part 113 is positioned below the second part 112 (see FIG. 4 Reference) High-intensity swing practice may be possible, and when the first part 113 is located below the second part 112 (see FIG. 4), the first part 113 is the second part 112 Compared to the case located on the upper side of (see FIG. 3), soft swing practice (elaborate impact and sensory practice in parallel) can be achieved.

According to the foregoing, according to the present cover 1, the strain on the wrist can be minimized due to the unbalance absorption function. In addition, since this cover 1 is light in weight and increases air resistance compared to the case where it is not installed, it is possible to perform sophisticated practice by maintaining the balance as much as possible with light weight.

In addition, according to the wearing method of the cover 1, it is possible to adjust the strength and practice according to various motions.

In addition, when the racket is stored with the cover 1 attached to the racket head 9 (for example, stored in a racket bag), impact to the racket can be prevented and the life of the racket can be increased. For example, if a lot of stress is applied to the racquet, the repulsive force decreases and needs to be replaced, but the replacement cycle may become longer.

Existing swing covers pass air through the hole formed part and push the air out of the part where the hole is not formed, so it is hard on the wrist and difficult to perform precise exercises such as impact, but according to this cover (1), the air is Since resistance is formed while passing through (1), sophisticated practice is possible. In addition, since this cover 1 can be mounted on the racquet head 9 with a light weight compared to the prior art, precise practice can be performed by minimizing the effect on the balance of the racquet with a light weight.

In addition, according to the above, the first part 113 may have a wind resistance of 80% and the second part 112 may have a wind resistance of 60%, so that the strength of the force input without affecting the balance of the racket Practice can be done according to.

In addition, according to the cover 1, the gut and the racket can be protected when the racket is stored.

That is, according to the present cover 1, an exerciser can be implemented that helps to improve fast swing training and rhythm, RBI, and impact timing by using air resistance to minimize the impact of racket balance.

In addition, since the intensity of air resistance can be adjusted, the intensity can be adjusted according to the type of training (serve, volley, forehand backhand, smashing, etc.) and the individual so that sophisticated practice can be achieved.

In addition, the present application provides a cover set according to an embodiment of the present application. A cover set according to an embodiment of the present application includes a plurality of the aforementioned covers 1.

In addition, the plurality of bone covers 1 have different air permeability. For example, at least one of the plurality of bone covers 1 may have a single air permeability (see FIG. 1 ) but may have an air permeability different from that of the other cover 1 having a single air permeability. In addition, the plurality of bone covers 1 may include the bone cover 1 including the above-described first part 113 and the second part 112. In this case, the first part 113 and the second part 112 may be included. At least one of the first part 113 and the second part 112 of the cover 1 including the two parts 112 includes the other first part 113 and the second part 112. It may have an air permeability different from that of at least one of the first part 113 and the second part 112 of (1). As such, the set may include a plurality of bone covers 1 in various combinations.

Accordingly, the plurality of bone covers 1 may have different air resistance, and the user may select a suitable air resistance among the plurality of bone covers 1 according to the training type (serve, volley, forehand backhand, smashing, etc.) and the person. You can practice by selecting this cover (1) with a figure and attaching it to the racquet head (9).

For example, it may be necessary to adjust the air resistance according to the practice part, such as an athlete, a woman, or a junior player. Accordingly, one of the plurality of bone covers 1 (for example, air resistance may have a higher air resistance than the other one. For example, the one bone cover 1 may have an air resistance of T80 , and the other cover 1 may have an air resistance of T60.

The above description of the present application is for illustrative purposes, and those skilled in the art will understand that it can be easily modified into other specific forms without changing the technical spirit or essential features of the present application. Therefore, the embodiments described above should be understood as illustrative in all respects and not limiting. For example, each component described as a single type may be implemented in a distributed manner, and similarly, components described as distributed may be implemented in a combined form.
