Description

Shuttlecocks for badminton and artificial feathers for shuttlecocks {ARTIFICIAL FEATHER FOR SHUTTLECOCK AND BADMINTON SHUTTLECOCK}

The present invention relates to an artificial feather for shuttlecocks and a shuttlecock for badminton, and more particularly, to an artificial feather for shuttlecock and a shuttlecock for badminton having excellent durability.

Background Art Conventionally, shuttlecocks for badminton are known to use a feather of a waterfowl feather (natural shuttlecock), and a feather artificially manufactured by nylon resin or the like (artificial shuttlecock). And natural shuttlecocks are more expensive than shuttlecocks using artificial feathers because it takes a long time to obtain a certain quality of such natural feathers. For this reason, shuttlecocks using artificial feathers of inexpensive and stable quality have been proposed (for example, Patent Document 1 (Japanese Patent Application Laid-Open No. 59-69086) and Patent Document 2 (Japanese Patent Application Laid-Open Publication No. 53-40335)). , And patent document 3 (Japanese Unexamined Patent Publication No. 38-1627).

In Patent Literature 1, an artificial feather for shuttlecock in which three rods made of fiber-reinforced resin are overlapped to form a feather shaft, and a pinned portion made of a thin plate of fiber dispersion resin is sandwiched between the three rods. Is disclosed. In addition, Patent Document 2 discloses an artificial feather for shuttlecock in which a collar portion is sandwiched between two shaft ends. In addition, Patent Document 3 discloses a shuttlecock in which a plurality of annular shafts arranged in an annular shape are bonded to each other on the outer circumferential side and the inner circumferential side by means of two cylindrically shaped chemical fiber cloths.

Patent Document 2: Japanese Patent Application Laid-Open No. 53-40335

Patent Document 3: JP 38-1627

However, in the artificial shuttlecock using the artificial feather for shuttlecock disclosed in Patent Document 1 or Patent Document 2 described above, according to the inventor's experiment, when actually used, the connection portion between the feather portion and the feather shaft is peeled off, or the stress is concentrated at the connection portion, resulting in breakage. In view of durability, it is inferior to the natural shuttlecock using the feather of the waterfowl. In addition, in the shuttlecock disclosed in Patent Document 3, since it is an integral member (chemical fiber cloth) in which all of the feather portions corresponding to the plurality of the shafts are connected, the shape and the flying characteristics of the shuttlecock are significantly different from those of the natural shuttlecock.

On the other hand, natural shuttlecocks using waterfowl feathers are increasingly difficult to obtain because they are increasingly difficult to obtain, so that emergency performance and durability are made using artificial feathers equivalent to natural shuttlecocks using waterfowl feathers. Artificial shuttlecocks are strongly demanded.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a shuttlecock artificial feather and badminton shuttlecock having emergency performance and durability equivalent to that of a shuttlecock using a waterfowl feather. .

The artificial feather for shuttlecock which concerns on this invention is equipped with a collar part and the shaft connected to the collar part. The feather portion includes a foam layer and a shaft fixing layer bonded to the foam layer by sandwiching the shaft. The foam layer and the shaft fixing layer have the same planar shape.

In this way, by using a foam layer as a collar part, the rigidity can be suppressed while suppressing the mass increase of a collar part, and the shape change of the artificial feather for shuttlecocks can be suppressed. As a result, since the emergency characteristic of the badminton shuttlecock using the said artificial feather for shuttlecocks can be stably maintained, the artificial feather and shuttlecock for shuttlecock excellent in durability can be realized.

In addition, by stacking the shaft fixing layer with the foam layer, the rigidity of the collar portion can be further improved. As a result, breakage (thin tearing, scattering) of the foam layer can be prevented. In addition, by pinching the shaft with the shaft fixing layer and the foam layer, reliable connection between the shaft and the collar can be realized.

The badminton shuttlecock which concerns on this invention is equipped with the hemispherical base main body and some artificial feathers for shuttlecocks connected to the said base main body. In this way, an inexpensive shuttlecock can be realized by an artificial feather. In addition, with regard to the emergency characteristics, emergency characteristics equivalent to those of the conventional shuttlecock using natural feathers can be realized.

According to the present invention, since the foam layer and the shaft fixing layer are formed by joining the shafts together to form the collar, the rigidity of the collar is improved while suppressing the mass increase of the collar, and as a result, the badminton shuttlecock has excellent durability and good emergency characteristics. And the artificial feather for shuttlecock constituting the shuttlecock.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in the following figures, the same code | symbol is attached | subjected to the same or corresponding part, and the description is not repeated.

(Embodiment 1)

With reference to FIG. 1 and FIG. 2, Embodiment 1 of the shuttlecock by this invention is demonstrated.

1 and 2, a shuttlecock 1 according to the present invention is for a plurality of shuttlecocks connected to a hemispherical base body 2 and a fixing surface portion formed with convex portions described later in the base body 2. The artificial feather 3, the fixing string-like member for fixing the plurality of artificial feathers 3 to each other, and the intermediate yarns 15 for maintaining the stacked state of the plurality of artificial feathers 3. Is done. The plurality of artificial feathers 3 (for example, 16 pieces) are arranged in an annular shape at the outer peripheral portion of the convex portion at the fixing surface portion of the base body 2. In addition, the some artificial feather 3 is mutually fixed by the string member. As the plurality of artificial feathers 3 are separated from the base main body 2, the inner diameters of the cylindrical bodies formed by the plurality of artificial feathers 3 are separated from the base main body 2 so that the distance between them increases. So as to increase accordingly).

The intermediate thread 15 acts as a fixing member for maintaining the stacked state of the plurality of artificial feathers 3. That is, the intermediate thread 15 is arrange | positioned so that the positional relationship of the some artificial feather 3 may be defined as mentioned later.

3 to 5, a first embodiment of an artificial feather for shuttlecock according to the present invention will be described.

3 to 5, the artificial feather 3 constituting the shuttlecock 1 shown in FIGS. 1 and 2 is divided into a collar portion 5 and a shaft 7 connected to the collar portion 5. Is done. The shaft 7 consists of the collar shaft part 8 arrange | positioned so that it may protrude from the collar part 5, and the fixed shaft part 10 connected to the collar part 5 in the substantially center part of the collar part 5. The flag shaft portion 8 and the fixed shaft portion 10 are arranged long on the same line, and constitute one continuous shaft 7. As shown in FIGS. 4 and 5, the collar portion 5 includes the foam layer 92 and the shaft fixing layer 91 and the foam layer 92 and the shaft fixing layer (arranged so as to sandwich the fixing shaft portion 10). 91 is composed of adhesive layers 93 and 94 for fixing each other. That is, in the collar part 5, the foam layer 92 and the shaft fixing layer 91 are laminated | stacked so that the fixing shaft part 10 may be pinched | interposed. In addition, in the collar part 5, in order to connect the foam layer 92 and the axial fixing layer 91 with each other, and to fix and fix the fixed shaft part 10, these foam layers 92, and the axial fixing layer 91, Adhesive layers 93 and 94 are disposed. In other respects, in the feather portion 5, in the case of constituting the shuttlecock 1, the adhesive layer 93 is laminated on the foam layer 92 located on the outer circumferential side. On this adhesive layer 93, the fixing shaft part 10 is arrange | positioned so that it may be located in the substantially center part of the said adhesive layer 93 and the foam layer 92. FIG. And one adhesive layer 94 is further arrange | positioned so that it may extend from this fixing shaft part 10 to the adhesive layer 93 on it. And the axial fixation layer 91 is arrange | positioned on this adhesive layer 94.

As can be seen from FIG. 5, in the artificial feather 3, the shaft 7 is bent toward the foam layer 92 side (that is, the outer peripheral side from the shuttle cock 1). In other words, the shaft 7 is bent so as to be convex toward the shaft fixing layer 91 side. In addition, although the artificial feather 3 has shown the state bent to the foam layer 92 side in the extending direction of the shaft 7, in FIG. 5, the direction which crossed the extending direction of the shaft 7 (for example, the shaft 7). In the width direction, which is the direction along the surface of the collar 5 as perpendicular to the extending direction of), a state in which the collar 5 is bent toward the foam layer 92 side (that is, the collar 5 is convex toward the shaft fixing layer 91 side). May be bent). In this case, even if the state in which the artificial feather 3 bends in the extending direction of the shaft 7 and the state in which the collar part 5 intersects with the extending direction of the shaft 7 occur simultaneously as described above, It may be good and only one of the bends may be generated. Such warpage is known in the art such as heat treatment of the constituent materials of the shaft 7 and the collar 5 or forming the constituent materials of the shaft 7 and the collar 5 in a state of initial bending. It can be realized by the method.

Here, as a material which comprises the foam layer 92, the foam of resin, for example, polyethylene foam (polyethylene foam) can be used more specifically. Moreover, also about the axial fixing layer 91, a resin foam can be used similarly. As the shaft fixing layer 91, for example, any material such as a film made of resin or the like or a nonwoven fabric can be used in addition to the polyethylene foam.

As for the adhesive layers 93 and 94, for example, double-sided tape can be used. In the artificial feather 3 shown in FIGS. 3 to 5, polyethylene foam is used as the foam layer 92 and the shaft fixing layer 91. It is preferable that the extrusion direction of this polyethylene foam is set to the direction shown by the arrow 95 of FIG. 3 and FIG. In this case, since the shaft 7 is connected and fixed with the collar part 5 so that it may cross | intersect the extrusion direction of the polyethylene foam shown by the arrow 95, the collar part 5 is the direction according to the extending direction of the shaft 7 Can reduce the probability of abnormal occurrence.

With reference to FIG. 6, the arrangement | positioning of the heavy thread 15 is demonstrated concretely.

As shown in FIG. 6, the twisted yarn 15 rotates around the shaft 7 of the artificial feather 3 and is in the state of being stacked in an adjacent artificial feather 3. In the part of (5), it is arrange | positioned so that the collar part 5 of the adjacent artificial feather 3 may pass through the area | region which mutually opposes (that is, between the laminated collar parts 5 laminated | stacked). In this way, since the core yarn 15 passes between the stacked collar portions 5 at the portion where the collar portions 5 are stacked, the stacking order of the collar portions 5 is replaced during use of the shuttlecock 1 (for example, For example, it is possible to suppress the occurrence of the problem that the stacking order of the collar 5 is replaced by the impact of the hit by the racket.

As shown in FIG. 1 and FIG. 2, the above-described heavy yarn 15 is disposed on the circumference so as to fix all of the plurality of artificial feathers 3 arranged in an annular shape to each other. The intermediate thread 15 can be arranged as shown in Figs. 1 and 2 by, for example, the worker sewing using a needle or the like. By doing in this way, the occurrence of the problem that the order of lamination | stacking of the collar part 5 is replaced during use of the shuttlecock 1 can be suppressed, and the shuttlecock 1 which shows the outstanding durability can be obtained.

In addition, one end of the sewing start and the other end of the sewing end are tied together in the yarn yarn 15 arranged on the circumference, and the part of the remaining thread is cut and removed near the knot. It is preferable to form a protective layer on the surface by applying an adhesive or the like to the knot. By forming such a protective layer, it is possible to prevent the knot from being released when the shuttlecock 1 is hit by the racket.

In addition, although the intermediate thread 15 can use arbitrary materials, such as cotton and resin, it is preferable to use the yarn made of polyester. In addition, it is preferable to use the light weight 15 as much as possible in order not to influence the center of the shuttlecock 1 etc. as much as possible. For example, as a yarn to be used, a yarn made of the 50th polyester may be used. In this case, the mass of the yarn used as the heavy yarn 15 is about 0.02 g. If it is such a mass, there exists some influence on the center position of the shuttlecock 1, but it is thought that there is little influence on an emergency characteristic. In addition, regarding the arrangement | positioning of the neutral yarn 15, the distance from the base main body 2 can be set arbitrarily.

As shown in FIG. 7, in the base main body 2, the convex part 61 is formed in the surface part for fixation. The surface shape of the convex part 61 is substantially circular shape (circular shape according to the arrangement | positioning of the insertion hole 63 into which the axis | shaft of the artificial feather 3 is inserted). Moreover, the side wall 62 of the convex part 61 is inclined with respect to the surface in the outer peripheral part of the fixing surface part (namely, as it falls from the surface of the outer peripheral part of the fixing surface part, The side wall 62 is in an inverse bank state so as to be wider).

In the outer peripheral part of the convex part 61 of the base main body 2, the insertion hole 63 for inserting the shaft 7 of the artificial feather 3 is formed, as shown in FIG. The insertion hole 63 is formed long in the direction along the extending direction of the side wall 62 of the convex part 61. The adhesive agent 64 is apply | coated as shown in FIG. 7 in the state in which the edge part of the shaft 7 was inserted in the said insertion hole 63. As shown in FIG. As shown in FIG. 7, the adhesive 64 extends from the end of the upper surface of the convex portion 61 to the outer circumferential surface of the fixing surface portion via the side wall 62 and is arranged to contact the shaft 7 as well. do. By the adhesive 64, the shaft 7 of the artificial feather 3 is firmly fixed to the base body 2. That is, the base main body 2 which concerns on this invention is a base body for shuttlecocks provided with the fixing surface part which fixes the shaft 7 of the artificial feather 3, The fixing surface part (base main body 2 of FIG. 2). ), A plurality of insertion holes 63 for inserting and fixing the shaft 7 of the artificial feather 3, which is a shuttlecock feather, and protruding from the surface of the fixing surface portion adjacent to the insertion hole 63. The convex part 61 is formed. In this way, when arranging the adhesive 64 in the state in which the shaft 7 is inserted into the insertion hole 63, the insertion hole 63 is adjacent to the insertion hole 63 in the insertion hole 63 (that is, in the shaft 7). The adhesive can be extended up to the convex part 61). For this reason, compared with the case where the convex part 61 does not exist, the area | region of the adhesive surface of the adhesive agent 64 and the base main body 2 can be enlarged, and the shape of an adhesive surface becomes a three-dimensional shape. Therefore, the adhesive strength of the adhesive agent 64, the base main body 2, and the shaft 7 of the artificial feather 3 can be improved.

Next, with reference to FIG. 8 and FIG. 9, the manufacturing method of the shuttlecock 1 shown in FIG. 1 and FIG. 2 and the artificial feather 3 for shuttlecocks is demonstrated.

First, with reference to FIG. 8, the manufacturing method of the artificial feather 3 for shuttlecocks which concerns on this invention is demonstrated. As shown in FIG. 8, in the manufacturing method of the artificial feather 3, a component material preparation process S10 is performed first. In this step (S10), the sheet-like material constituting the shaft 7 constituting the artificial feather 3, the foam layer 92 and the shaft fixing layer 91 shown in Figs. 4 and 5, the adhesive layer 93, 94) prepare double-sided tape to be Moreover, if the planar shape of these sheet-like members and a double-sided tape is larger than the size of the collar part 5 shown in FIG. 3, it can be set as arbitrary shapes. As the sheet-like member to be the foam layer 92, for example, a material having a thickness of 1.0 mm and a weight per unit area of 24 mm / m 2 can be used as polyethylene foam (formed as a foam of polyethylene). As the sheet-shaped member to be the axial fixing layer 91, a material of polyethylene foam, 0.5 mm in thickness, and 20 g / m 2 in weight per unit area can be used. Moreover, the weight per unit area of the double-sided tape used as the adhesive layers 93 and 94 can be 10 g / m <2>.

Next, as shown in FIG. 8, a bonding process S20 is performed. In this step (S20), a double-sided tape, which should be the adhesive layer 93, is attached on the main surface of the sheet-like member that is to be the foam layer 92. And the fixed shaft part 10 of the shaft 7 is arrange | positioned on the said double-sided tape. Moreover, the sheet-like member which should become the axial fixing layer 91 with the double-sided tape which should become the adhesive layer 94 on the surface facing the fixing-shaft part 10 is laminated | stacked and bonded from the top. As a result, it is possible to obtain a structure in which the fixing shaft portion 10 of the shaft 7 is sandwiched between the sheet-shaped member to be the foam layer 92 and the sheet-shaped member to be the shaft fixing layer 91.

Next, a post-processing step (S30) is performed. Specifically, the unnecessary part (that is, the area | region other than the part which should become the feather part 5) of the laminated sheet-shaped member which should become the feather part 5 is cut off. As a result, an artificial feather 3 as shown in Figs. 3 to 5 can be obtained. And the foam layer 92 etc. are contracted by heat-processing, for example, applying heat from the foam layer 92 side with respect to the said artificial feather 3, for example. As a result, as shown in FIG. 5, the state in which the shaft 7 and the collar part 5 were bent can be implement | achieved. In addition, another method may be used to realize a state where the shaft 7 and the collar portion 5 as shown in FIG. 5 are bent. For example, you may employ | adopt the method of using the shaft 7 of the curved shape from the beginning.

Next, with reference to FIG. 9, the manufacturing method of the shuttlecock 1 shown in FIG. 1 and FIG. 2 is demonstrated. As shown in FIG. 9, the preparation process (S100) is performed first. In this preparation process S100, structural members of the shuttlecock 1, such as the base main body 2 (tip member) of the shuttlecock 1, the artificial feather 3 mentioned above, are prepared.

As the manufacturing method of the base main body 2, any conventionally well-known method can be used, For example, when artificial resin is used as a material which should be the base main body 2, the material of the base main body 2 is first used. A block is prepared and cut into outline shape by cutting. At this time, processing is performed by adding the hemispherical portion of the tip portion and the height of the convex portion. In addition, you may use the method of forming the external shape of the convex part 61 and the insertion hole 63 by cutting. As the material of the base body 2, a natural material such as cork may be used. In addition, when using the above-mentioned artificial resin, ionomer resin foam, EVA (ethylene vinyl acetate copolymer), polyurethane, PVC (polyvinyl chloride), polyethylene, polypropylene, etc. are used, for example. It is available. In addition, as the manufacturing method of the artificial feather 3, the manufacturing method shown in FIG. 8 mentioned above can be used.

Next, an assembling step (S200) is performed. In the said assembling process (S200), the origin of the shaft 7 of the some artificial feather 3 mentioned above is inserted and fixed to the insertion hole 63 in the fixing surface part of a base main body. In addition, the plurality of artificial feathers 3 are fixed to each other by a string member. In addition, sewing is performed so that the intermediate yarn 15 for maintaining the overlapping state of the feather portion may be arranged as shown in FIG. 6. In this way, the shuttlecock 1 shown in FIG. 1 and FIG. 2 can be manufactured. In addition, as a fixing member which fixed the some artificial feather 3 mutually, you may use arbitrary members, such as a ring-shaped member, without being limited to the string-shaped member mentioned above.

Moreover, as a material of the said fixing member, arbitrary materials, such as resin and a fiber, can be used, for example. For example, the aramid fiber or glass fiber may be impregnated with the resin (for example, a thermosetting resin) using the aramid fiber or the glass fiber as a string member, and the fixing member obtained by FRP formation by curing the resin may be used. . By forming FRP in this way, the strength and rigidity of the fixing member can be improved. As the thermosetting resin, for example, an epoxy resin or a phenol resin can be used. Thus, when thermosetting resin is used for FRP formation, when a heating process is performed in the process for fixing a fixing member with the shaft 7, etc., FRP of a fixing member can be easily performed by thermosetting resin simultaneously.

With reference to FIG. 10 and FIG. 11, the artificial feather which comprises the 1st modified example of Embodiment 1 of the shuttlecock by this invention is demonstrated.

The artificial feather 3 shown in Figs. 10 and 11 basically has the same structure as the artificial feather 3 shown in Figs. 3 to 5, but the shape of the adhesive layer 93 is different. Specifically, in the artificial feather 3 shown in FIGS. 10 and 11, the adhesive layer 93 disposed between the foam layer 92 and the fixing shaft portion 10 is a foam layer (at the fixing shaft portion 10). It consists of the center part which covers the surface located in the 92 side, and the long extension part connected to the said center part and toward the side end part of the foam layer 92 and the axial fixing layer 91 from the side end part of the fixing shaft part 10. As shown in FIG. The extending portion extends between the side end portion of the fixing shaft portion 10 and the side end portion of the foam layer 92, but does not reach the side end portion of the foam layer 92. In this case, in the vicinity of the side end portions of the foam layer 92 and the shaft fixing layer 91, the adhesive layer 94 is fixed in contact with the foam layer 92 directly. Thus, even if the structure which arrange | positions the adhesive layer 93 partially is employ | adopted, if the foam layer 92, the axial fixing layer 91, and the fixed shaft part 10 can be firmly connected with each other, it is shown in FIGS. The same effect as that of the artificial feather 3 can be obtained.

With reference to FIG. 12, the artificial feather which comprises the 2nd modified example of Embodiment 1 of the shuttlecock by this invention is demonstrated. 12 corresponds to FIG. 11.

The artificial feather 3 shown in Fig. 12 basically has the same structure as the artificial feather 3 shown in Figs. 10 and 11, but the fixing shaft portion is provided not only for the adhesive layer 93 but also for the adhesive layer 94 as well. It is set as the structure arrange | positioned only in the vicinity of (10). In this case, the foam layer 92 and the shaft fixing layer 91 are in direct contact with each other in the vicinity of the outer peripheral ends of the foam layer 92 and the shaft fixing layer 91 (that is, the portions where the adhesive layers 93 and 94 are not disposed). As the contact portion is fused, the foam layer 92 and the shaft fixing layer 91 are fixed to each other. By such a configuration, the foam layer 92, the shaft fixing layer 91 and the fixing shaft portion 10 can be firmly connected and fixed by the adhesive layers 93 and 94. In addition, by reducing the areas of the adhesive layers 93 and 94, the mass of the artificial feather 3 can be reduced as a result.

(Embodiment 2)

With reference to FIG. 13, the artificial feather which comprises Embodiment 2 of the shuttlecock by this invention is demonstrated. 13 corresponds to FIG. 4.

The shuttlecock provided with the artificial feather 3 shown in FIG. 13 basically has the same structure as the shuttlecock 1 shown in FIGS. 1 and 2, and the artificial feather 3 is basically It has the same structure as the artificial feather 3 shown in FIGS. However, in the artificial feather 3 shown in FIG. 13, the artificial feather 3 of the shuttlecock in Embodiment 1 mentioned above that the resin film 81 is used as the axial fixation layer which comprises the feather part 5 is mentioned. Is different. In addition, since the film 81 relatively thinner than the foam of the resin used for the axial fixing layer 91 shown in FIGS. 3 to 5 is used as the axial fixing layer, the thickness of the foam layer 92 is described above. It is preferable to make it thicker than the thickness of the foam layer 92 of the artificial feather 3 in the form 1.

Even when the shuttlecock 1 as shown in Figs. 1 and 2 is formed using the artificial feather 3 having such a configuration, the same effects as the effect of the shuttlecock 1 shown in Figs. You can get it. In addition, in the artificial feather 3 shown in FIG. 13, since the thickness of the foam layer 92 is made relatively thicker than the thickness of the foam layer 92 of the artificial feather 3 in Embodiment 1 mentioned above, The foam layer 92 sufficiently secures the strength of the collar 5. As a result, similar to the artificial feather 3 shown in Figs. 3 to 5, it is possible to prevent the occurrence of a problem that the film 81 is broken due to the hit by the racket and the fragments of the film 81 are scattered. have.

As the film 81, any material can be used. For example, as a film of polyethylene (PE), a material having a thickness of 10 µm and a weight per unit area of 10 g / m 2, or a film of polypropylene (PP) As a film of 20 占 퐉 thickness, 18g / m2 weight per unit area, a film of polyethylene terephthalate (PET), 12 占 퐉 thickness, 17g / m2 weight per unit area, and a film of polyamide (PA). A material of 15 µm and a weight per unit area of 18 g / m 2 can be used.

(Embodiment 3)

With reference to FIG. 14, Embodiment 3 of the shuttlecock which concerns on this invention is described. 14 corresponds to FIG. 4.

The shuttlecock provided with the artificial feather 3 shown in FIG. 14 basically has the same structure as the shuttlecock 1 shown in FIGS. 1 and 2, and the artificial feather 3 is basically Although the structure similar to the artificial feather 3 shown in FIGS. 3-5 is provided, the point which uses the nonwoven fabric 71 as an axial fixing layer differs from the artificial feather 3 shown in FIGS. Thus, when the nonwoven fabric 71 is used as an axial fixing layer, in order to ensure the intensity | strength of the collar part 5, the thickness of the foam layer 92 is made thick enough. By doing in this way, generation | occurrence | production of the problem that the collar part 5 deforms also by the hit of a racket can be suppressed. For example, as the nonwoven fabric 71, a material having a weight per unit area of 15 g / m 2 can be used as the nonwoven fabric of polyester. In this case, as the foam layer 92, as polyethylene foam, a material having a thickness of 1.5 mm and a weight per unit area of 30 g / m 2 can be used.

(Fourth Embodiment)

With reference to FIG. 15 and FIG. 16, the artificial feather which comprises Embodiment 4 of the shuttlecock by this invention is demonstrated.

The shuttlecock provided with the artificial feather 3 shown in FIGS. 15 and 16 basically has the same structure as the shuttlecock 1 shown in FIGS. 1 and 2, and the artificial feather 3 is It basically has the same structure as the artificial feather 3 shown in Figs. 3 to 5, but is located at the front end side of the collar portion 5 (from the fixing shaft portion 10 to the end portion connected to the collar shaft portion 8). The reinforcement member 21 is arrange | positioned at the other end side to be different. As shown in FIG. 16, the reinforcing member 21 is sandwiched and fixed between the adhesive layer 93 and the foam layer 92.

The reinforcing member 21 and the foam layer 92 may be connected by heat fusion, for example, and another adhesive layer (for example, a double-sided tape, between the reinforcing member 21 and the foam layer 92) Or an adhesive bond layer) may be arrange | positioned and fixed. Arbitrary resin films can be used as a material of this reinforcing member 21. For example, a polyethylene film having a thickness of 10 μm may be used as the reinforcing member 21. The thickness of the reinforcing member 21 is, for example, 1 µm or more and 20 µm or less, and more preferably 5 µm or more and 15 µm or less. As the reinforcing member 21, any material other than the above-described polyethylene film may be used.

By arranging such a reinforcing member 21 at the distal end of the artificial feather 3, when hitting the shuttlecock 1 with a racket, the distal end side of the artificial feather 3 (reinforcing member) due to the impact of the impact. The breakage of the foam layer 92 on the side where the 21 is disposed can suppress the occurrence of the problem that the fixing shaft portion 10 is exposed or that the fixing shaft portion 10 is peeled from the foam layer 92. .

With reference to FIG. 17, the modification of the artificial feather shown in FIG. 15 and FIG. 16 is demonstrated. 17 corresponds to FIG. 16.

The shuttlecock provided with the artificial feather 3 shown in FIG. 17 basically has the same structure as the shuttlecock 1 shown in FIGS. 1 and 2, and the artificial feather 3 is basically provided. 15 and 16 has the same structure as that of the artificial feather 3, but the other reinforcing member 31 is disposed on the outer circumferential side of the foam layer 92 at the tip end side of the artificial feather 3. 15 and the artificial feather 3 shown in FIG. It is preferable that the planar shape of the reinforcing member 31 be basically the same as the planar shape of the reinforcing member 21. Moreover, the planar shape of the reinforcing member 31 is made smaller than the planar shape of the reinforcing member 21. Or you may employ | adopt the structure made larger than the planar shape of the reinforcing member 21. In this case, the tip end of the artificial feather 3 can be protected more reliably.

Further, the reinforcing member 31 may be adhered to the outer circumferential surface of the foam layer 92 using, for example, an adhesive layer such as a double-sided tape or an adhesive, and the reinforcing member 31 may be heat-sealed to the foam layer 92. good. In addition, although the material and thickness of this reinforcement member 31 may be similar to the material and thickness of the reinforcement member 21, you may make it the material or thickness different from the reinforcement member 21.

18 and 19, another modified example of the artificial feather shown in FIGS. 15 and 16 will be described.

The shuttlecock provided with the artificial feather 3 shown in FIG. 18 and FIG. 19 basically has the same structure as the shuttlecock 1 shown in FIGS. 1 and 2, and the artificial feather 3 is Basically, it has the same structure as the artificial feather 3 shown in FIG. 15 and FIG. However, in the artificial feather 3 shown in FIG. 18 and FIG. 19, the state of the reinforcement member arrange | positioned at the front end side of the artificial feather 3 differs from the artificial feather 3 shown in FIG. 15 and FIG. That is, in the artificial feather 3 shown in FIGS. 18 and 19, as the reinforcing member 41, a string-like body like a thread intersects with the extending direction of the shaft 7 (for example, extending of the shaft 7). As a direction perpendicular | vertical to a direction, it arrange | positions at the front end side of the collar part 5 elongate in the direction along the surface of the collar part 5). As the reinforcing member 41, for example, a yarn made of a resin or other natural fiber can be used. In addition, although the size etc. (thickness) of the said string body can be arbitrarily selected, For example, the thread of the number 60 can be used with the said yarn made from polyester. As shown in FIG. 19, the reinforcing member 41 made of such a string body is sandwiched and fixed between the adhesive layer 93 and the foam layer 92.

In addition, the reinforcement member 41 can be arrange | positioned in arbitrary positions other than between the adhesive layer 93 and the foam layer 92 mentioned above in the thickness direction of the collar part 5. For example, it may be bonded to the outer circumferential side surface of the foam layer 92 (the surface opposite to the side bonded to the adhesive layer 93 in the foam layer 92) using an adhesive or the like. Alternatively, the reinforcing member 41 may be disposed between the adhesive layer 93 and the adhesive layer 94. Alternatively, the reinforcing member 41 may be disposed between the adhesive layer 94 and the shaft fixing layer 91. Further, the reinforcing member 41 may be joined to the outer circumferential side surface of the shaft fixing layer 91 (the surface opposite to the surface bonded to the adhesive layer 94 in the shaft fixing layer 91) using an adhesive or the like. Even when using such a reinforcing member 41 made of a string body, the same effects as in the case of using the artificial feather 3 shown in FIGS. 15 and 16 can be obtained. In addition, since the reinforcement member 41 of the artificial feather 3 shown in FIGS. 18 and 19 is a cord-shaped body, the sheet-like reinforcement member 31 in the artificial feather 3 shown in FIGS. 15 and 16 is shown. Lighter and softer deformation. For this reason, in the shuttlecock manufactured using the artificial feather 3 shown to FIG. 18 and FIG. 19, a feeling of a hit improves more.

With reference to FIG. 20, another modified example of the artificial feather shown in FIG. 15 and FIG. 16 is demonstrated.

The shuttlecock provided with the artificial feather 3 shown in FIG. 20 basically has the same structure as the shuttlecock 1 shown in FIGS. 1 and 2, and the artificial feather 3 is basically provided. Has the same structure as the artificial feather 3 shown in FIGS. 18 and 19. However, in the artificial feather 3 shown in FIG. 20, the point where the reinforcement member which consists of a string body is arrange | positioned at the front end side of the several blade part 5 differs from the artificial feather 3 shown in FIG. 18 and FIG. . That is, in the artificial feather 3 shown in FIG. 20, the plurality of reinforcing members 41 to 43 intersect the string body with the extending direction of the shaft 7 (perpendicular to the extending direction of the shaft 7). It is one direction, long in the direction along the surface of the collar part 5, and is arrange | positioned at the front end side of the collar part 5. Although the some reinforcement members 41-43 are arrange | positioned long in parallel with each other, at least one part of the some reinforcement members 41-43 may be long extended in the direction which mutually crossed. In this manner as well, the same effects as those of the artificial feather 3 shown in FIGS. 18 and 19 can be obtained, and the tip portion of the feather portion 5 can be more reliably reinforced.

15 and 16 may be arranged in combination with at least one of the sheet-like reinforcing members 31 and the reinforcing members 41 to 43 made of the string-like body described above. As the reinforcing members 41 to 43, an elongated sheet-like member cut out in a small tag shape may be used. In addition, in order to reduce the mass of the reinforcing member 31, one or more openings may be formed in the reinforcing member 31, for example.

(Embodiment 5)

With reference to FIG. 21, the artificial feather which comprises Embodiment 5 of the shuttlecock by this invention is demonstrated.

The shuttlecock provided with the artificial feather 3 shown in FIG. 21 basically has the same structure as the shuttlecock 1 shown in FIGS. 1 and 2, and the artificial feather 3 is basically It has the same structure as the artificial feather 3 shown in FIGS. 3-5, but is long in the feather part 5 along the extending direction of the shaft 7 (in FIG. 21, specifically parallel to the axis 7). The point where the axial reinforcement 44 arrange | positioned long is arrange | positioned differs. As the axial reinforcing member 44, for example, a thread as a string body can be used. As a thread, although the thread which consists of arbitrary materials can be used, you may use, for example, a resin thread. As resin which comprises a thread, you may use polyester, for example. More specifically, as the axial reinforcing member 44, for example, a yarn made of polyester 60 may be used.

The reinforcing member 44 is sandwiched and fixed between the adhesive layer 93 and the foam layer 92, for example, similarly to the reinforcing member 21 shown in FIG. 16.

The axial reinforcement member 44 and the foam layer 92 may be connected by, for example, heat fusion, and another adhesive layer (eg, between the axial reinforcement member 44 and the foam layer 92) may be used. For example, you may fix and connect by double-sided tape or adhesive bond layer). As a material of this axial reinforcement member 44, you may use arbitrary resin films instead of the thread mentioned above. For example, as the axial reinforcing member 44, a polyethylene tag having a small tag shape (or linear shape) may be used. As the material of the axial reinforcing member 44, any material other than the above-described polyethylene film may be used.

By arranging such an axial reinforcing member 44 in the collar portion 5 of the artificial feather 3, when the shuttlecock 1 is hit by a racket, the artificial feather 3 is caused by the impact of the hit. The occurrence of the problem that the collar portion 5 tears in the direction intersecting the extending direction of the shaft 7 can be suppressed.

In addition, the axial reinforcement member 44 can be arrange | positioned in arbitrary positions other than between the adhesive layer 93 and the foam layer 92 mentioned above in the thickness direction of the collar part 5. For example, the axial reinforcing member 44 is bonded to the outer circumferential side surface of the foam layer 92 (the surface opposite to the side bonded to the adhesive layer 93 in the foam layer 92) using an adhesive or the like. You may be. Alternatively, the axial reinforcing member 44 may be disposed between the adhesive layer 93 and the adhesive layer 94. Alternatively, the axial reinforcing member 44 may be disposed between the adhesive layer 94 and the axial fixing layer 91. The axial reinforcing member 44 may be bonded to the outer circumferential side surface of the axial fixing layer 91 (the surface opposite to the surface bonded to the adhesive layer 94 in the axial fixing layer 91) using an adhesive or the like.

With reference to FIG. 22, the modification of the artificial feather shown in FIG. 21 is demonstrated.

The shuttlecock provided with the artificial feather 3 shown in FIG. 22 basically has the same structure as the shuttlecock 1 shown in FIGS. 1 and 2, and the artificial feather 3 is basically Has the same structure as the artificial feather 3 shown in FIG. However, in addition to the axial reinforcement member 44, the artificial feather 3 shown in FIG. 22 also has the reinforcement member 41 in the front-end | tip side similarly to the artificial feather 3 shown in FIG. The reinforcing member 41 is a string-shaped member, and is disposed long in a direction intersecting the shaft 7 (specifically, a direction orthogonal to the shaft 7). In this way, in addition to the effect obtained by the artificial feather 3 shown in FIG. 21, the effect obtained by the artificial feather 3 shown in FIG. 18 can also be obtained. Instead of the reinforcing member 41, another reinforcing member shown in Embodiment 4 of the present invention may be used.

In addition, the reinforcement member 41 and the axial reinforcement member 44 shown in FIG. 22 may be arranged in the same layer in the thickness direction of the collar part 5, and may be arrange | positioned in another layer. In addition, the reinforcing member 41 and the axial reinforcing member 44 may be constituted by an integral member, or may be constituted by separate members.

(Embodiment 6)

With reference to FIG. 23, the artificial feather which comprises Embodiment 6 of the shuttlecock by this invention, and its manufacturing method are demonstrated. 23 has shown the cross section in the direction along the axis of the artificial feather 3, and respond | corresponds to FIG.

The shuttlecock provided with the artificial feather 3 shown in FIG. 23 basically has the same structure as the shuttlecock 1 shown in FIGS. 1 and 2, and the artificial feather 3 is basically It has the same structure as the artificial feather 3 shown in FIGS. 3 to 5, but the point where the shaft fixing layer 91 and the shaft 7 are directly connected is the artificial feather 3 shown in FIGS. different. Even with such a configuration, the same effects as in the artificial feather 3 shown in FIGS. 3 to 5 can be obtained.

Next, the manufacturing method of the artificial feather 3 shown in FIG. 23 is demonstrated. The manufacturing method of the artificial feather 3 shown in FIG. 23 is basically the same as the manufacturing method of the artificial feather shown in FIG. 8, but the content of the bonding process S20 differs. That is, in the manufacturing method of the artificial feather 3 shown in FIG. 23, the receiving stand 51 and the holding plate 52 which are manufacturing jig | tool as shown in FIG. 23 are used. The upper surface of the base 51 and the lower surface of the pressing plate 52 face each other. Then, by stacking the pressing plate 52 on the base 51, the base 5 and the shaft 7 of the artificial feather 3 become the shape of the contact portion between the base 51 and the pressing plate 52. In order to form voids, recesses are formed in the upper surface and the feather surface. As can be seen from FIG. 23, the upper surface and the lower surface are curved in correspondence with the shape of the artificial feather 3 formed.

In the manufacturing method of the artificial feather 3 shown in FIG. 23, after implementing the structural material preparation process S10 shown in FIG. 8, the following process is implemented as a bonding process S20. That is, the sheet-like member which should be the axial fixing layer 91 is first provided on the upper surface of the receiving stand 51. And the shaft 7 is arrange | positioned on the said sheet-like member. In addition, after attaching the double-sided tape which should be the adhesive layer 93 to one side of another sheet-shaped member which is to be the foam layer 92, the other sheet-like member is mounted on the shaft 7. At this time, the other sheet-like member is disposed so that the surface on which the double-sided tape is attached is opposite to the shaft 7 in the other sheet-like member. Then, the pressing plate 52 is pressed toward the receiving base 51 from above the other sheet-like member. In this way, the sheet-like member to be the shaft fixing layer 91 and the other sheet-like member to be the shaft 7 and the foam layer 92 are joined. After that, the same as in the first embodiment, the post-treatment step (S30) is carried out. Specifically, the artificial feather 3 as shown in FIG. 23 can be obtained by removing the unnecessary part of a sheet-like member and another sheet-like member, and arranging a shape.

Although some overlap with embodiment mentioned above, the characteristic structure of this invention is listed below.

The artificial feather 3 for shuttlecock which concerns on this invention is provided with the collar 5 and the shaft 7 connected to the collar 5. The collar portion 5 includes a foam layer 92 and a shaft fixing layer (axial fixing layer 91, film 81, and nonwoven fabric 71) bonded to the foam layer 92 by sandwiching the shaft 7. The foam layer 92 and the axial fixing layer have the same planar shape.

In this way, by using the foam layer 92 as the collar part 5, the rigidity is improved while suppressing the mass increase of the collar part 5 (suppressing deformation by a strike), and the artificial feather 3 for shuttlecocks The change in shape of the can be suppressed. As a result, since the emergency characteristic of the badminton shuttlecock 1 using the shuttlecock artificial feather 3 can be stably maintained, the shuttlecock artificial feather 3 and the shuttlecock 1 excellent in durability can be realized.

In addition, by stacking the axial fixing layer (the axial fixing layer 91, the film 81, the nonwoven fabric 71) with the foam layer 92, the rigidity of the collar portion 5 can be further improved. As a result, breakage (thin tearing, scattering) of the foam layer 92 can be prevented. In addition, by pinching and fixing the shaft 7 by the shaft fixing layer and the foam layer 92, it is possible to realize a reliable connection between the shaft 7 and the collar 5.

The artificial feather 3 for shuttlecock may further include adhesive layers 93 and 94 positioned between the foam layer 92 and the shaft fixing layer. In this case, the connection between the foam layer 92 and the shaft fixing layer can be made stronger by the adhesive layers 93 and 94, and the connection diagram between the foam layer 92 and the shaft fixing layer and the shaft 7 is provided. I can harden it. As a result, the durability of the artificial feather 3 for shuttlecocks can be improved.

In addition, even when the shaft 7 and the collar part 5 are comprised by the material which cannot be directly connected (for example, heat-sealing, etc.), the shaft 7 and the collar part 5 by the contact bonding layers 93 and 94 are mentioned. Can be bonded. Therefore, the freedom degree of material selection with respect to the shaft 7 or the collar part 5 can be enlarged.

In the artificial feather 3 for shuttlecock, the adhesive layers 93 and 94 are disposed at a position overlapping at least the shaft 7 (specifically, the fixing shaft portion 10). That is, the adhesive layers 93 and 94 fix the foam layer 92 and the shaft fixing layer to the shaft 7. In this case, the reliable connection between the shaft 7 and the collar 5 can be realized by the adhesive layers 93 and 94. As a result, the durability of the artificial feather 3 for shuttlecock can be improved reliably.

In the artificial feather 3 for shuttlecock, the adhesive layers 93 and 94 are the entire region between the foam layer 92 and the shaft fixing layer, as shown in Figs. 4, 13, 14, 16, 17 and the like. It may be arranged in. In this case, durability of the whole collar part 5 can be improved by the contact bonding layers 93 and 94. FIG.

In the said artificial feather 3 for shuttlecocks, as shown in FIG. 5, the collar part 5 foams in at least one of the directions which cross | intersect the extending direction of the shaft 7 and the extending direction of the shaft 7. It may be bent to the layer 92 side. In this case, the artificial feather 3 for shuttlecock can be made into the shape closer to the feather (natural feather) of a waterfowl. For this reason, when the shuttlecock 1 is manufactured using the said artificial feather 3 for shuttlecocks, the shape of the shuttlecock 1 can approach the shuttlecock using a natural feather. Moreover, the emergency characteristic of the shuttlecock 1 manufactured using the said shuttlecock artificial feather 3 can also be adjusted by changing the grade of the said curvature. As a result, the emergency characteristic of the artificial shuttlecock 1 manufactured using the artificial feather 3 for shuttlecock can approach the emergency characteristic of the shuttlecock using the conventional natural feather.

In the artificial feather 3 for shuttlecock, the foam layer 92 may be thicker than the shaft fixing layer (the shaft fixing layer 91, the film 81, the nonwoven fabric 71). In this case, by thickening the thickness of the collar portion 5 on the foam layer 92 side where the apparent density is relatively small, while ensuring the necessary thickness of the total path of the collar portion 5, the weight of the collar portion 5 increases. Can be avoided.

In the artificial feather 3 for shuttlecock, the shaft 7 is located on the opposite side to the base portion and the base portion connected to the base main body 2 of the shuttlecock 1, and is sandwiched between the foam layer 92 and the shaft fixing layer. It may also include a true tip. As shown in FIGS. 15-17, the said artificial feather 3 for shuttlecock may also be equipped with the reinforcement members 21 and 31 arrange | positioned so that it may overlap with the front-end | tip part of the shaft 7. As shown to FIG. In this case, by arranging the reinforcing members 21 and 31 at the distal end of the shaft 7 most likely to be damaged when the shuttle cock 1 strikes, the possibility of the distal end being damaged by the impact can be reduced.

In the artificial feather 3 for shuttlecocks, the reinforcing members 21 and 31 are arranged on the foam layer 92 side rather than the shaft 7 in the thickness direction of the collar 5. In this case, when the artificial feather 3 is provided in the base main body 2 so that the foam layer 92 side faces outward from the shuttlecock 1, the tip part of the shaft 7 is set as mentioned above. The reinforcing members 21 and 31 can be effectively protected from the impact from the outside.

In the artificial feather 3 for shuttlecock, at least one of the foam layer 92 or the shaft fixing layer may be formed using an extrusion method, and the extrusion direction of the foam layer 92 or the shaft fixing layer in the extrusion method. , The extending direction of the shaft 7 may intersect. Here, the foam layer 92 or the shaft fixing layer formed by the extrusion method is likely to be torn in the extrusion direction. Therefore, when the shaft 7 is fixed as described above, the shaft 7 becomes a reinforcing member of the foam layer 92 or the shaft fixing layer. As a result, the durability of the collar part 5 can be improved.

In the artificial feather 3 for shuttlecock, the foam layer 92 is made of foamed polyethylene, and the weight per unit area is preferably 10 g / m 2 or more and 30 g / m 2 or less, and a thickness of 0.5 mm or more and 2 mm or less. In addition, it is preferable that the axial fixation layer 91 consists of foamed polyethylene, and the weight per unit area is 10 g / m <2> or more and 30 g / m <2> or less, and thickness is 0.3 mm or more and 1 mm or less. In this case, in the artificial feather 3 for shuttlecock, the center position and total mass close to a natural feather can be realized. Moreover, the badminton shuttlecock 1 manufactured using the said artificial feather 3 for shuttlecocks can also make emergency characteristics equivalent to that of a natural shuttlecock.

It is preferable that the said artificial feather 3 for shuttlecocks is equipped with the axial reinforcement member 44 extended in the collar part 5 along the extending direction of the shaft 7. In this case, tearing of the collar part 5 in the direction which cross | intersects the extending | stretching direction of the shaft 7 can be suppressed.

The badminton shuttlecock 1 which concerns on this invention is equipped with the hemispherical base main body 2 and some artificial feather 3 for shuttlecocks connected to the said base main body 2. In this way, the inexpensive shuttlecock 1 can be realized by the artificial feather 3. In addition, with regard to the emergency characteristics, emergency characteristics equivalent to those of the conventional shuttlecock using natural feathers can be realized.

In the badminton shuttlecock 1, the artificial feather 3 for shuttlecock is arranged in a ring shape with respect to the base main body 2 and fixed to the base main body 2 so that the adjacent collar portions 5 partially overlap each other. You may be. The badminton shuttlecock 1 may further include a heavy yarn 15 which is a string body that regulates relative movement or deformation of the collar portion 5 in the plurality of shuttlecock artificial feathers 3. In this case, the deadlock prevention of the collar part 5 can be reliably performed.

It should be thought that embodiment disclosed this time is an illustration and restrictive at no points. The scope of the present invention is shown by above-described not description but Claim, and it is intended that the meaning of a Claim and equality and all the changes within a range are included.
