Description

Shuttlecock

The present invention relates to a shuttlecock, and more particularly, to improve the productivity while allowing the production of a shuttlecock of uniform dimensions, and the lifespan of the shuttlecock long by preventing the flagpole bending and breaking of the fixed line portion when the shuttlecock strikes It is related to the shuttle cock to improve the feel feel while improving the hitting feeling, flight speed, trajectory and distance does not change, and when the artificial feather having a hair on the sheet does not cause tangling of the hair when hitting.

As a game using a shuttlecock, there are badminton, techminton, and the like. A general badminton competition shuttlecock is a bird feather 20 inserted into a head 10 made of a hemispherical cork, as shown in FIG. Is 4.5 ~ 5.5g, cork diameter is 25mm ~ 28mm, the number of feathers should be 16 pieces, the length from the tip of the feather to the top of the head should be 64mm ~ 70mm, the diameter of the feather is 58mm ~ 68mm, head ( The upper surface of 10) and the outer circumferential surface of the feather 20 have an angle of about 65 ° to 75 °, the maximum speed is 320km / h, and the player hits the underhand at one end of the court to the inner back boundary line. It should fall between 53 and 99 cm.

Techminton is a game developed and operated by the applicant of the present application, and its contents are disclosed in detail in Korean Patent Application No. 10-2009-0065628. It is possible to play in the space.

By the way, such badminton or techminton shuttlecocks use bird feathers, but it is not easy to select feathers having a certain size, weight and angle, and usually only one or four good feathers for one duck are excellent. There is a problem in the production of shuttlecocks, and thus, selecting and arranging feathers that can be used for shuttlecocks among several feathers requires manual labor and productivity is reduced, and it is difficult to use feathers that are curved at the same mass and at the same angle. Since it is not easy, there is a problem that the quality is not constant, such as the characteristics are not uniform and have an error.

In addition, the feather of the natural bird is that the feather branch extends to both sides and the hair is formed on both ends of the flagpole, with the flagpole being excessively bent or its thickness does not reach a certain degree, but in many cases it cannot be used. In the case of such feathers, many parts except the flagpole, that is, the state of the flagpole and the hair are in good condition, but if the flagpole is not satisfied, it can not be used and discarded.

In order to solve the problem of the shuttlecock using natural feathers, a technique for shuttlecock using artificial feathers is disclosed in Korean Utility Model Publication No. 20-2009-0002547 (prior art 1), and Patent No. 10-2007-0121416 (prior art 2). have.

However, the prior art 1 has a problem that the angle and spacing of the flagpole is not exactly matched to form the flagpole to which the feather is attached one by one separately, so as to fit in the head, the prior art 2 is the angle of the feather branch and hair Because it is not formed separately for each flagpole, it is formed into a barrel, so that the flight of air is not able to perform a flight motion suitable for the competition standards because it does not receive the resistance of air and the hair of a known natural shuttlecock in flight.

In addition, since the shuttlecock collides with the racket, the flagpole's elasticity is very important in order to prevent damage of the shuttlecock. However, the flagpoles of the prior arts 1 and 2 described above are produced by injection without any detailed description of the flagpole's structure. From the base material, it was not possible to secure a space for absorbing the impact on the end face, which could cause damage.

In addition, the conventional artificial shuttlecock has a problem that the flagpole is formed at 0 degrees with respect to the tangent of the circle connecting the end of the flagpole, so that when the hair is attached, it is impossible to obtain a rotational force such as natural feathers.

On the other hand, in the above-mentioned natural or artificial shuttlecock, as shown in Fig. 2, a fixing line 20b for fixing the spacing and the angle of the flagpole is installed on the flagpole 20, which is fixed to the flagpole 20 lifespan. To make the shuttlecock more resilient and feel better, seawater is a very important factor.

Since the fixed line 20b is usually injection molded integrally with the flagpole, the fixed line and the flagpole have the same strength, and the inward face of the fixed line is formed in a plane. As it is difficult to adjust the elasticity, the shuttlecock does not absorb the shock caused by the collision with the racket 60, as shown in FIG. 3, and thus the desired flight trajectory, speed, and distance cannot be obtained, Problems such as breaking occur.

In other words, when hitting with a racket during high clearing or smashing, the headpiece 10 is not fitted from the head, but the flagpole 20 and the hair, especially from the tip of the hair, which causes the flagpole 20 to swing back and forth, left and right, In this process, if the fixed line has a strong strength, the flagpole may not absorb the flow of the flagpole, and as shown in FIG. 3, the flagpole may be broken or broken at the fixed line portion. There is a problem in that the flight direction does not have a distance from the desired flight curve, such as shaking.

In addition, since the flagpole 20 should be as light as possible, when the fixing line 20b is thinly formed, the elasticity in the inner / outer direction of the shuttle ball is lowered, so as to be crushed as shown in FIG. This takes a flight distance and speed and trajectory is not satisfactory, there was also a problem falling shot.

Meanwhile, shuttlecocks using artificial feathers are mostly made of nonwoven fabrics or resins.

However, since these artificial feathers are composed of a single plate of hair W, the hair W is tangled as shown in FIG. 5, which is caused by hitting the racket when high clearing or smashing the head 10. ) Since the flagpole 20 and the hair (W) is not fitted from the first part, and the flagpole 20 is swayed back and forth and left and right because of this, the hair (W) is tangled, and thus the hair (W) is tangled Natural feathers do not cause a big problem because the hairs are separated one by one, but the normal artificial feathers are formed in a sheet-like sheet of hair (W), so if the tangled, they do not have a desired flight curve and distance such as severe shaking during flight and flight direction shaking. There is a problem that can not be.

An object of the present invention is to provide a shuttlecock that can use a portion of the feather that was not available due to the flagpole problem of the conventional natural feathers while improving the problem of bad feel during use due to bad elasticity of the artificial shuttlecock.

In addition, while preventing the damage of the shuttlecock during the strike of the shuttlecock, the fixed line that plays an important role in the flight trajectory, distance and speed is light and excellent in elasticity so that the life of the shuttlecock is long and has excellent quality, and the conventional artificial feathers Another purpose is to prevent hair entanglement so that flight speed, trajectory and distance are satisfactory at the time of hitting.

Features of the present invention for achieving the above object, the base, the flagpole is integrally extended to have a predetermined angle from the centerline of the head with a plurality of bases having a predetermined distance to the base coupled to the head; Shuttlecock composed of hair attached to the end of the flagpole.

The injection molding is formed so as to form a groove along the longitudinal direction in the center of the inner surface of the flagpole, the fixing band is integrally injection molded in the center of the flagpole, the flagpole with respect to the tangent of the circle connecting the end of the flagpole from the center of the shuttlecock It is formed to have an angle of 0-30 degrees.

Further, the feather branches are formed to be spaced apart from each other in an symmetrical inclination on the upper left and right sides of the flagpole corresponding to the hair, and a ring is formed at the end of the feather branch.

In addition, the hair is used either by thermally fusion-molding microfibers in a fibrous form, by foaming, or by terminating portions of natural feathers, that is, terminating portions of feather feathers.

In addition, the present invention is characterized in that the fixing line formed integrally with the flagpole in order to fix the spacing and angle of the flagpole, the groove is formed on the inner side in the longitudinal direction and has a shape protruding outward.

According to the present invention having the configuration as described above, it is possible to provide a shuttlecock excellent in all the most important weight, flagpole spacing, diameter, angle, elasticity conditions in the shuttlecock.

In addition, by making grooves into the shuttlecock inward plane of the flagpole, that is, the surface that is bonded to the hair, the thickness is moderate but the weight is reduced.The flagpole is thinner and more elastic than the thickness of the flagpole to improve hitting feeling, reduce weight, and collide with the racket. When the damage rate can be reduced, and by forming a groove in the flagpole can be used to cut and glue only the feather branch and hair portion of the feather that could not be used in the conventional flagpole problem, there is an effect that can increase the utilization of the feather.

In addition, by injection molding the flagpole into a single one, including a fixed belt, it is possible to provide an accurate shuttlecock to the flagpole, angle, and diameter to fly at the correct distance.

When the yarn is formed into a sheet form by compressing the yarn, the center line and branch lines connected to the flagpole are further compressed to secure the elasticity and form stability of the hair, and the thickness of the hair is gradually thinned outward from the center line, resulting in dullness. It helps to reduce the weight and give a good feeling.

In addition, as the groove is formed in the fixed line, the fixed line becomes lighter, and thus the whole shuttlecock becomes lighter, so that the impact when the impact is transferred to the elbow of the user does not occur, and the impact of the artificial feather hits the racket. Since it has sufficient elasticity and has excellent elasticity, the flagpole's flagpole is not broken or broken so that the life of the shuttlecock is prolonged and flight trajectory and distance speed are not reduced.

In addition, the shuttlecock using the artificial feather is not tangled with each other when the hair on the sheet is not entangled with each other, so that the flight to the unwanted place due to shaking during flight.

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

제 1실시예First embodiment

6 to 11, the shuttle cock is integrally formed to have a constant angle from the centerline of the head 30 while having a plurality of regular intervals in the base 42 is coupled to the head 30 as shown in FIGS. Each cross section has a triangular shape, the injection-molded flagpole 40, the yarn is formed in the form of a sheet to form a groove 46 in the longitudinal direction in the center of the inward surface of the shuttlecock, respectively bonded to the end of the flagpole 40 The hairline 50 includes a centerline 55 coupled to the flagpole 40, a feather branch 52, and a comb line 53.

In the above, in the middle of the flagpole 40, the fixing band 48 is integrally formed and the fixing band 48 prevents the flagpole 40 from being separated from inside, outside and left and right when being hit by the racket. The reason for fixing the flagpole 40 in this way is that if the spacing of the flagpole 40 is changed and the angle is changed, the shuttlecock is shaken to travel as much as the desired course and distance.

Accordingly, the fixing band 48 is formed to a certain dimension through the injection molding, the length in the horizontal direction with the center line of the shuttlecock is molded into 0.5 ~ 3mm, the length in the vertical direction is 0.2 ~ 2mm, the fixing belt 48 ) Is thicker than the range, the feeling of hitting falls, it is difficult to control the weight. This is because it is good to hit with the flagpole when it is high clear or smashed.

And, the flagpole 40 is formed to be twisted from 0 to 30 ° from the tangent along the circumference of the shuttle cock as shown in Figure 10 can be reduced or increased the angle to increase the number of revolutions according to the wind, which is determined during the molding process It is molded at an angle, but not deformed during use.

In addition, the flagpole 40 has a cross-section, including an isosceles triangle shape or an isosceles triangle shape or arc shape, is symmetrically formed with respect to the center, and the portion corresponding to the racket in the shuttlecock is the flagpole 40 and the hair 50. Therefore, the flagpole 40 is preferably an isosceles triangle shape in which the outer two sides of the shuttlecock are isosceles, as shown in FIG. 9, and when formed in this way, the flagpole can be prevented from inside, outside, left and right twisting, and elasticity is generated.

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

On the other hand, the base 42 is formed so that the fastener 41 is integrally protruded to the bottom in contact with the head 30 to be plugged into the head 30, the fastener 41 is cylindrical to the bottom And a fixing protrusion 41b protruding outwardly from the lower end of the protruding wall 41a and protruding wall 41 to which the fastener 41 is fastened. An insertion groove 46 having a shape corresponding to the 41a is formed, so that the protruding wall 41a is inserted into the insertion groove 46 to be fixed by the fixing protrusion 41b at the end.

And, the material for forming the hair 50 in the above can be used any material that makes a yarn as a yarn, such as polyester, nylon, silk, cotton, etc. Shuttlecock hair should be very light, so low denier (5 denier) Using less than 20 ~ 100g per 1㎡, and light and have some strength, so heat the thinly coated yarn so that it will not be distracted by fusion.

In this case, in the case of the yarn that is not easily dissolved in heat, the yarn is thinly disposed in a sheet form, and then laminated or coated with a heat-bondable material such as bond, latex, and vinyl on one or both surfaces thereof, and then molded. In addition, further fusion of latex, vinyl and the like may be applied to a yarn that can be heat-sealed to give a desired hardness.

Thus, the hair 50 formed by heat-sealing has a horizontal longest length of 1 to 2.5 cm, a vertical longest length of 2.5 to 5 cm, and a thickness of 0.5 to 1.5 mm as shown in FIGS. 11 and 12. Shaped so as to become thinner, the center line 55 constituting the hair 50 is 0.2 to 0.5mm thinner than the maximum thickness of the hair 50, while the center line 55 width of the surface combined with the flagpole 40 The centerline 55 of the surface is formed to the size that can accommodate the width of the flagpole 40 and is not coupled to the flagpole 40 is formed narrower than the width of the flagpole 40, the flagpole 52 is the hair 50 It is formed 0.2 ~ 0.5mm thinner than the maximum thickness, and the comb line 53 extending again from the feather branch 52 is formed 0.1 ~ 0.2mm thinner than the maximum thickness of the hair 50, the shape of the hair 50 Make a mold for thermal fusion to fit.

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

On the other hand, as shown in Fig. 13, the hair 50 formed of a sheet-like yarn may be bonded to the flagpole 40 which is injection molded integrally as described above, but as shown in Fig. 14, the flagpole 55a of natural feathers. ) The natural hair 50 cut into a certain shape can be bonded to the flagpole 40 which is injection molded integrally as described above.

In addition, the hair may be foam-molded with polypropylene (PP), polyethylene (PE), urethane, or the like and adhered to the flagpole.

제 2실시예Second embodiment

The shuttlecock is composed of a head 30, a flag pole 40 engaged with the head 30, and a hair 50 formed on the upper left and right sides of the flag pole 40, as shown in Figs.

15 and 17, the flagpole 40 is integrally formed to have a predetermined angle from the centerline of the head 30 while having a plurality of flagpoles 40 at regular intervals on the cylindrical base 42. The cross section of each of the flagpoles 40 formed as described above is injection-molded so that the grooves 46 are formed along the longitudinal direction at the center of the inward surface of the shuttlecock in a triangular shape.

In addition, the flagpole 40 is further formed to be spaced apart from each other to be symmetrically inclined symmetrically to the upper left and right sides of the flagpole 40 corresponding to the hair 50 is formed with a groove (47a) in the center, the end of the ring 48 is formed.

Moreover, in order to fix the space | interval and angle of the said flagpole 40, the fixed line 49 integrally formed with the flagpole 40 is bent the center in the longitudinal direction, as shown in FIG. It is formed to have a shape that is formed and protrudes outward.

The fixed line 49 has a longitudinal length of 0.3 to 3mm, a transverse length of 0.3 to 3mm, and can be used by adjusting the horizontal and vertical lengths according to a desired hitting feel.

For example, if the length is long and the length is short, the strength is weak and soft, and in the opposite case, the strength is high and rigid.

In addition, the hair 50 is formed in a sheet shape and adhered to the end of the flagpole 40 of the flagpole 40 and has a centerline (not shown) at a thickness thinner than other portions in the center to facilitate engagement with the flagpole 40. ).

In the case of hitting the shuttlecock formed in this way, the ring 48 of the flagpole 40 to hold the feather branch 47 of the adjacent flagpole 40 so that the arrangement position of the hair 50 is mixed or changed with each other inside and outside It is possible to prevent the hair 50 from being entangled by not happening, and thus, when the hair 50 is prevented from being entangled, a desired flight curve and a distance can be obtained.

This is because when the high clearing or smashing, hitting the racket does not fit from the head portion 30, but from the flagpole 40 and the hair 50, and because of this the flagpole 40 is shaken back and forth, left and right, because the hair ( 50) hairs are tangled.

In this way, if the hair is tangled, the natural feathers are separated one by one, so no big problem occurs. However, since the normal artificial feather is formed in the shape of a hair sheet, the tangled feathers do not have a distance from the desired flight curve, such as severe shaking during flight and flight direction. There is a problem.

In addition, when high clearing or smashing, hitting with the racket does not fit from the head 30, but from the end of the flagpole 40 and the hair 50, especially the flagpole 40 and hair 50, Flagpole 40 is shaken back and forth, left and right, the fixed line 49 is formed thinly by the groove (49a) has elasticity and has the necessary strength due to the '<' shaped cross-section shuttle shuttle when hitting As soon as it is returned to its original position, the flagpole is not broken or broken.
