Embodiment
The basic structure > of < artificial badminton ball
Fig. 1 and Fig. 2 are for explaining orally the outside drawing of the basic structure of the artificial badminton ball 1 that comprises artificial feather 10.Fig. 1 is the perspective view that artificial badminton ball is watched from base portion one side.Fig. 2 is the perspective view that artificial badminton ball is watched from a side of artificial feather 10.
Artificial badminton ball 1 comprises base portion 2, many pieces of artificial feather 10 and the wire assemblies 3 for artificial feather 10 is interfixed that imitate natural feather.The structure of base portion 2 for instance, is the cork base covering with thin layer.Base portion 2 has semi-spherical shape and the flat surface of diameter between 25mm to 28mm.With annular form, the circumference along flat surface described in this embeds the root of many pieces of artificial feathers 10.The spread pattern of many pieces of artificial feathers 10 makes that space is more larger away from described base portion 2 therebetween.In addition, as shown in drawings, the spread pattern of each piece of described artificial feather 10 also makes itself and adjacent another piece of artificial feather 10 overlapping.Therefore, many pieces of artificial feathers 10 have formed shirt rim part 4.Many pieces of artificial feathers 10 with wire assembly 3(for example, cotton thread) interfix.
The structure of < artificial feather (comparative example 1) >
Fig. 3 is in comparative example 1, the outside drawing of artificial feather 10.In addition, Fig. 4 A-Fig. 4 C is in comparative example 1, the key diagram of artificial feather 10.Fig. 4 A is the plane of artificial feather 10 while watching from front.Fig. 4 B is the plane of artificial feather 10 while watching from the back side; Fig. 4 C is the schematic diagram of artificial feather 10 while watching from top to bottom.Note, already described assembly indicates with same numeral.
Artificial feather 10 comprises that accessory pinna part 112 and pinna rachis part 14. accessory pinna parts 112 are the parts corresponding to the accessory pinna of natural feather, and pinna rachis part 14 is the parts corresponding to the pinna rachis of natural feather.Above-below direction in accompanying drawing is defined as along the direction of pinna rachis part 14, a side that is provided with accessory pinna part 112 be defined as " on ", and a contrary side is defined as D score.In addition, the left and right directions in accompanying drawing is defined as the direction (width) of extending from pinna rachis part 14 along accessory pinna part 112.In addition, in the accompanying drawings, the state that the definition of fore-and-aft direction embeds base portion 2 based on artificial feather 10 defines.Hereinafter, in inciting somebody to action with reference to the accompanying drawings, defined top to bottom, left and right, front and rear direction is described assembly.
Accessory pinna part 112 in comparative example 1 is pellet modules, the accessory pinna shape of simulation natural feather.This accessory pinna part 112 can be utilized as like that structures such as adhesive-bonded fabric, resins.In the situation that using adhesive-bonded fabric, at Surface Machining one deck strengthened coat of accessory pinna part 112, the fiber of adhesive-bonded fabric is loosening when preventing from hitting shuttlecock.This strengthened coat can form by applying resin, can adopt the whole bag of tricks for this reason, like that such as infusion process, spraying process, rolling method etc.In addition, notice that described strengthened coat can be machined on the single or double of accessory pinna part 112.In addition, this strengthened coat can be machined on the whole surface or its part surface of accessory pinna part 112.
Pinna rachis part 14 is long and thin assemblies, imitates the pinna rachis of natural feather, and this assembly supports accessory pinna part 112.Pinna rachis part 14 comprises: accessory pinna support section 14A, is supporting accessory pinna part 112 region from top to bottom; And from the outstanding pinna rachis part 14B of accessory pinna part 112.This pinna rachis part 14B is the part of the pen feather (note, this part is also called rhaehis) corresponding to natural feather.The lower end of this pinna rachis part 14B embeds and is fixed on base portion 2.
The cross section of the described pinna rachis part 14 in figure shows as square.But the cross section of this pinna rachis part 14 can be rhombus, circle or oval.In addition, pinna rachis part 14 can be difformity on above-below direction, thus, for example, its upside for circle downside be square.
In addition, the described pinna rachis part 14 in figure is processed, make the size of the shape of its cross section become large toward its downside.But the size of the shape of its cross section can be balanced unconverted on above-below direction, or the size of its shape of cross section can change smoothly.
Note, described pinna rachis part 14 and accessory pinna part 112 can be separation or one.For example, when usining resin during as the material of described pinna rachis part 14 and accessory pinna part 112, described pinna rachis part 14 and accessory pinna part 112 can be by carrying out one plastotype with mould injection molding.In addition, when both are separated, accessory pinna part 112 can be supported on accessory pinna and support on the back side of part 14A, or accessory pinna part 112 can be supported on the front of accessory pinna support part 14A.In addition, accessory pinna part 112 can consist of double leaf, and can be configured to: accessory pinna supports part 14A to be clipped between the double leaf of accessory pinna part 112.In addition, accessory pinna part 112 can embed accessory pinna and support part 14A inside.
In above-mentioned artificial feather 10, when " intersection " may occur in shuttlecock and impacted, show that the context (stratification state) of adjacent accessory pinna part 112 has become contrary relation.If intersected, occur, even if continue so to impact shuttlecock, be also difficult to recover the initial context of adjacent accessory pinna part, cause the unsettled problem of flight track.Note, in natural feather, because accessory pinna is not lamellar form, but by the set of the feather body that is called ramus growing from pinna rachis, even if intersect, the ramus of accessory pinna also can slip over the ramus of another adjacent accessory pinna, therefore, when shuttlecock is impacted, can from crossing condition, return to original state easily.
Fig. 5 is in comparative example 1, overlooks from top to bottom the schematic diagram of a plurality of accessory pinna parts.As shown in FIG., the arrangement mode of a plurality of accessory pinna parts 112 makes each accessory pinna part gradually change with the partly overlapping angle of another accessory pinna.Note, hereinafter the lap between described adjacent accessory pinna part represents with T.In addition, the space between adjacent accessory pinna part represents with S.
For example, in Fig. 5, when shuttlecock is impacted, adjacent accessory pinna part 112 trails once (until they are not overlapping) on left and right directions, and while then getting back to original state, the overlap condition of accessory pinna part 112 can be reversed.When described intersection occurs, possibly cannot obtain stable flight characteristics.
Therefore, preferably, should take measures to prevent to intersect when shuttlecock from being impacted.Can by by adjacent accessory pinna part 112 bonding/fuse together or be stitched together with assemblies such as lines, still, a problem is in the case, prevents the required work trouble of the structure of intersecting.
The structure of < artificial feather (comparative example 2) >
In comparative example 2, accessory pinna part is provided with cut out portion, forms thus the lap T that is less than comparative example 1 between adjacent accessory pinna part.By this kind of way, can easily suppress the generation intersecting.For example, when the accessory pinna part 112 as in Fig. 5 does not exist overlapping (T is zero substantially) mutually substantially, be not easy to intersect.
Fig. 6 shows in comparative example 2, the perspective view of the ordered state of the accessory pinna part 212 of artificial badminton ball 1.Fig. 7 is in comparative example 1, watches from top to bottom the schematic top view of accessory pinna part ordered state.Note, for ease of statement, Fig. 6 and Fig. 7 have only represented the part of a plurality of accessory pinna parts 212.In addition, due to except accessory pinna part, similar to comparative example 1 of comparative example 2 structure, thereby be not repeated at this.
Compare with the accessory pinna part 112 in comparative example 1, the side of the accessory pinna part 212 in comparative example 2 on width processed a cut out portion 212a.Thus one, because the accessory pinna part 212 in comparative example 2 is provided with cut out portion 212a, the length of its each accessory pinna part 212 on its width is smaller than accessory pinna part 112 in comparative example 1 length on width.Therefore, each the lap T between adjacent accessory pinna part 212 is less than each the lap T(Fig. 5 in comparative example 1).
Thus, by reducing lap T, adjacent accessory pinna part 212 is not easy to intersect (putting upside down of overlap condition), even be subject to impacting the impact of shuttlecock.Therefore, the intersection of accessory pinna part 212 can be prevented.But in this comparative example 2, owing to being provided with cut out portion 212a in accessory pinna part 212, the space S between adjacent accessory pinna part 212 becomes than large in comparative example 1.
The flight track of artificial badminton ball 1 and rotation are limited by the air-flow in each the space S between accessory pinna part.If the space S between adjacent accessory pinna part 212 is too large, in comparative example 2, number of revolutions will increase and surpass suitable numerical value, cause flight track significantly crooked.Contrast, if space S is too little, number of revolutions will become and be less than suitable numerical value, the breakpoint that causes being suitable for flight track is no longer applicable.
< artificial feather structure (embodiments of the present invention) >
In one embodiment of the present of invention, by regulating space S, even if reduce the lap T between accessory pinna part, not affected by lap and obtain stable flight characteristics.
Fig. 8 shows in one embodiment of the present of invention, the top view of accessory pinna part 12 ordered states of artificial badminton ball 1.Fig. 9 shows in one embodiment of the present of invention, the perspective view of accessory pinna part 12 ordered states of artificial badminton ball 1.Figure 10 and Figure 11 are in one embodiment of the present of invention, the side view of accessory pinna part 12 ordered states of artificial badminton ball 1.These accompanying drawings for convenience of description for the purpose of, all only shown the part of a plurality of accessory pinna parts 12.
In addition, Figure 12 A to Figure 12 C is in one embodiment of the present of invention, the key diagram of a slice artificial feather 10 of artificial badminton ball 1.Figure 12 A is the plane of this artificial feather 10 while watching from front; Figure 12 B is the plane of this artificial feather 10 while watching from the back side; Figure 12 C is the sectional view that Figure 12 A and Figure 12 B cut open along A-A line.Note, the assembly of having described represents with identical label, and it is described in this omission.
Described accessory pinna part 12 has cut out portion 12a, similar to the cut out portion 212a of accessory pinna part 212 in comparative example 2.The shape of this cut out portion 12a reduces the lap of adjacent accessory pinna part 12.Specifically, cut out portion 12a is made as curve shape (spill), corresponding to the curve shape (convex) of the right end part of accessory pinna part 12.In addition, accessory pinna part 12 has aileron part (corresponding to ledge) in its positive left distal end.This aileron part 12b is towards the direction of another the accessory pinna part 12 adjacent with accessory pinna part 12 outstanding (more specifically, towards another accessory pinna part 12 fronts adjacent with accessory pinna part 12 crisscross).In one embodiment of the present of invention, the angle θ forming between the front of accessory pinna part 12 and aileron part 12b in Figure 12 c is 90 degree (its error is the positive and negative several years).
