Description

Shuttlecock

The present invention relates to a shuttlecock, and more particularly, to a badminton shuttlecock that allows a shuttlecock having a uniform size to be manufactured and productivity to be improved.

As shown in FIG. 1, a bird's feather 20 is inserted into a head 10 made of a semi-spherical cork, as shown in FIG. 1, and a shuttlecock for a badminton game is shown in FIG. , The weight is 4.5 ~ 5.5g, the diameter of the cork is 2.5 ~ 2.8cm, the number of feathers should be 16, the length from feather tip to head upper face should be 6.4 ~ 7.0cm, The upper surface of the head 10 and the outer circumferential surface of the feather 20 have an angle of about 65 to 75 degrees and the maximum speed is 320 km / h, and the player can hit with the under hand at one end of the coat, It should fall between 53 and 99 cm inside the boundary line.

As a game developed and operated by the applicant of the present application, Korean Patent Application No. 10-2009-0065628 discloses details of the game, and both the racket, the court, and the shuttlecock are formed smaller than the batminton, It is possible to play in space.

However, the shuttlecock for Batminnton or TechMinton uses bird feathers, but it is not easy to pick feathers with a certain size, weight and angle, and usually only 4 to 6 hairs per duck can be used There is a problem in the production of shuttlecock. Since the work of selecting and sorting the feathers which can be used in the shuttlecock among several feathers must be manually performed, the productivity is decreased and the produced products are also easy to use the same mass and the same angle There is a problem in that the quality is not constant because the features are not uniform and have an error.

The feathers of the natural birds are formed in such a manner that the flagpole is extended to both sides of the flagpole at the end of the flagpole with the center of the flagpole at the center, and the flagpole is formed with hairs. Even in the case of such feathers, there are many cases where the flagpole except the flagpole, that is, the flagpole and the fur, are in good condition. However, if the flagpole is not satisfied, it can not be used and is discarded.

In order to solve the problem of the shuttlecock using such a natural feather, a technique for a shuttlecock using an artificial feather is proposed in the public utility model 20-2009-0002547 (Prior Art 1), the patent document 10 (Patent Document 2) However, the prior art 1 has a problem in that the angle and spacing of the flagpole are not precisely matched because the flagpoles to which the feathers are attached are formed separately and are inserted into the head. In the prior art 2, Since the flags of the natural shuttlecock and the hairs do not receive the resistance of the known natural shuttlecock during the flight process, it is impossible to perform a flight exercise suitable to the competition standard.

Since the shuttlecock collides with the racket, the elasticity of the flagpole is very important in order to prevent the breakage of the shuttlecock. However, the conventional flagpoles of the prior arts 1 and 2 do not have a detailed description of the structure of the flagpole, There is a possibility of damage due to the fact that a space for absorbing the impact on the cross section can not be secured.

In addition, the conventional artificial shuttlecock has a problem that since the flagpole is formed at 0 degree with respect to the tangent line of the circle connecting the end of the flagpole, the rotational force like natural feathers can not be obtained when the wing is attached.

The object of the present invention is to provide a shuttlecock which can use a part of a feather which has been unusable due to a flagpole problem in a conventional natural feather while improving the problem that the flagpole of the artificial shuttlecock is poor in elasticity so that the feeling of impact is poor.

According to an aspect of the present invention, there is provided a golf club head comprising: a head; a flagpole formed integrally with the base coupled to the head so as to have a predetermined angle with respect to a center line of the head, And a wing attached to the flagpole end of the flagpole.

Wherein each of the flagpoles has a triangular cross section formed by injection molding so that a groove is formed along the longitudinal direction at the center of the inward surface of the shuttlecock and a fixed band is integrally injection molded at the center of the flagpole, 0 " to the tangent of the circle connecting the < / RTI >

The wings may be formed by thermally fusing a fine yarn in a fibrous form, or formed by foaming, or alternatively, from the end of a natural feather, or the end of a feathery flagpole.

According to the present invention having such a configuration as described above, it is possible to provide a shuttlecock which is excellent in all of the most important weight, flagpole spacing, circle diameter, angle, and elasticity conditions in a shuttlecock, It is possible to reduce the weight of the racquet by reducing the weight, and by reducing the thickness of the flagpole, the flagpole is thinner and more elastic than the flagpole.

In addition, by injecting the flagpole into one including the fixing band, it is possible to provide accurate shuttlecock up to the flagpole, angle, and circle diameter, so that it can fly at the correct distance.

In addition, by forming grooves in the flagpole, it is possible to improve the elasticity of the flagpole and to use only the feathers of the feathers which are not used as the problem of the flagpole.

When the wing portion is formed by pressing the yarn to form a sheet, the center line and branch lines connected to the flagpole are further pressed to secure the elasticity and the form stability of the wing portion, and the thickness of the wing portion is gradually thinned outward around the center line. And helps to give a good feeling.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in FIGS. 2 to 7, the shuttlecock according to the present invention includes a base 42 coupled to the head 30, and a plurality of flagpoles 44 are spaced apart from the center line of the head 30 by a predetermined angle. Each of the flagpoles 44 formed integrally and extending in this manner has a triangle-shaped cross-section, which is formed by projecting the flagpole portion 40, the flagpole portion 44, and the projecting portion 46 so as to form a groove 46 along the longitudinal direction at the center of the inward surface of the shuttlecock. The yarn is formed in the form of a sheet along the shape of the center line 55, the flagpole 52, the comb line 53 and the fur 54 which are joined to the end of the flagpole 44 of the flagpole portion 40 And a wing portion (50).

The flagpole 40 is formed in such a manner that a fixed band 48 is integrally formed in the middle of the flagpole 44 constituting the flagpole 40, The reason why the flagpole 44 is fixed is that if the distance between the flagposts 44 is changed and the angle is changed, the shuttlecock is shaken, to be.

Accordingly, the flagpole fixing band 48 is formed to have a certain size through injection molding, the length in the horizontal direction to the center line of the shuttlecock is 0.5 to 3 mm, and the length in the vertical direction is 0.2 to 2 mm. 48) is thicker than the range, the feeling of impact is lowered, it is difficult to control the weight, and when it is thinner than the range, the elasticity is lowered and deformation occurs. Because the flagpole is hit when the high clear or the smash is done, and the flagpole elasticity is good because the feeling of hit is good.

6, the flagpole 44 is formed to be twisted from 0 to 30 degrees from the tangent line along the circumference of the shuttlecock, so that the angle can be reduced or increased in order to increase the number of revolutions in accordance with the wind. But is not deformed during use.

5, the flagpole 44 forms a triangle in cross section, because the flagpole 44 is the flagpole 44 and the fur 54 that fit the racquet in the shuttlecock, Should be an isosceles triangle shape, which is an isosceles triangle. When formed into a triangle shape, it is possible to prevent inward, outward, leftward, and rightward warpage, and elasticity is generated.

The diameter of the flagpole is preferably 6 to 7 cm.

A fastener 41 is integrally formed on the base 42 of the flagpole 40 so as to protrude downward from the surface of the base 30 to be in contact with the head 30. The fastener 41 is inserted into the head 30, 41 has a protruding wall 41a formed in a cylindrical shape protruding downward and a fixing protrusion 41b protruding outward from a lower end of the protruding wall 41a. An insertion groove 46 having a shape corresponding to the projection wall 41a is formed in the insertion hole 30 so that the projection wall 41a is inserted into the insertion groove 46 and fixed by the fixing projections 41b at the end.

The material forming the wing portion 50 may be any material such as polyester, nylon, silk, or cotton yarn, and the feathers of the shuttlecock should be very light, Denier), it should be thin about 20 ~ 100g per 1m2, and it should be light and have a certain strength, so heat is applied to the thin yarn to prevent the yarn from being disturbed by fusion.

At this time, in the case of a yarn which is not readily dissolvable in heat, the yarn is arranged in a thin sheet form, and then a material which can be fused by heat such as bond, latex or vinyl is laminated or coated on one surface or both surfaces thereof. In addition, fusing latex, vinyl, or the like in this way can be applied to a heat-sealable yarn to give desired hardness.

As shown in FIGS. 7 and 8, the wings 50 formed by heat fusion are formed so as to have a transverse length of 1 to 2.5 cm, a maximum length of 2.5 to 5 cm, a thickness of 0.5 to 1.5 mm, The thickness of the wing portion 50 is equal to the thickness of the wool 54 and the center line 55 corresponding to the flagpole 44 is 0.2 to 0.5 mm more than the thickness of the wool 54. [ The width of the center line 55 of the face coupled with the flagpole 44 is formed to be small enough to accommodate the width of the flagpole 44 and the center line 55 of the face that is not engaged with the flagpole 44, 44 and the brim 52 is formed to be 0.2 to 0.5 mm thinner than the thickness of the bristles 54 and the comb stripe 53 extending from the brim 52 again has a thickness that is less than the thickness of the bristles 54, And a metal mold for heat fusion is manufactured so as to conform to the shape of the wing portion 50. As shown in Fig.

The mold presses the sheet at 120 to 250 DEG C for 0.5 to 5 seconds.

On the other hand, as shown in Fig. 9, the wing portion 50 formed by molding the yarn into a sheet can be adhered to the integrally injection-molded flagpole 40 as described above. However, as shown in Fig. 10, The natural wing portion having the tail end, that is, the landing portion, the comb and the hair portion 52a, 53a and 54a cut into a certain shape may be adhered to the flap portion 40 integrally injection-molded as described above.

Further, the blade portion may be foam-molded with polypropylene (PP), polyethylene (PE), urethane or the like and adhered to the flagpole.
