Abstract

A shuttlecock comprises a nose (2) and a frusto-conical skirt (3) fixed thereto. The skirt (3) is formed of an inner layer (5) and an outer layer (6) of plastics sheet material generally lying aginst one another. The outer layer is formed with a plurality of spaced elongate channels (8) which are open towards the inner layer and the inner layer is formed with a plurality of spaced elongate channels (9) corresponding to and aligned with those of the outer layer and opening towards the outer layer such that the channels (8, 9) of the inner and outer layers (5, 6) of the skirt co-operate to form hollow stiffening columns (10). Elongate stiffening members are located within the hollow stiffening columns and are bonded to both layers (5, 6) of the skirt.

Description

Improved shuttlecock

The present invention is about shuttlecock.

A lot of club badminton player only use the shuttlecock of feather, and all senior match regulations are used the shuttlecock of feather.This is because the shuttlecock of the artificial feather of neither one can operate in the mode of the shuttlecock of enough similar feathers.So existing design some aspects or all aspects below all descended: the rigidity in skirt section, on different speed, pass the velocity of rotation of air, leave the initial velocity on racket surface, the sound of square stance and/or sensation, the characteristic of rolling of soft when beating " pure " square stance; The profile of shuttlecock.

This is not that the shuttlecock of saying feather is regarded as optimal.The shuttlecock of nature feather must not be on all four, and the producer must select, and is usually further selected by the player.They compare the influence that is subject to atmospheric conditions more with synthetic material.Their life-span seldom can reach whole fixture, usually changes their flight characteristics in the process of rally.Because feather is easy to disarray, the player can indulge in " doing some little tricks " by ruining them.Because flying quality is not uniform, assessment is a subjective things, has known that some players refuse to use the shuttlecock that can play little trick.

The invention of most of artificial designs is all relevant with rotating naturally of the shuttlecock that imitates feather.They have obtained success in various degree, but normally under the situation of the structural integrity that damages the skirt section, obtain.Therefore, when impacting heavily, the air-flow in skirt section and advance faster than the shuttlecock of feather.It is too far away that this just makes this match deflection hit the player firmly.Existing artificial design lacks rigidity can cause that also the skirt section damages with the bump of racket the time, nose portion usually leaves the racket face and falls like this, rather than resembles and move upward the shuttlecock of feather.The rigidity in the skirt section of feather provides a knock-on response at once, so tumbling rate is very fast.

Now almost do not have what purpose to go to imitate the pneumatic character of feather, this than the common realization of player and recognize even more important.The solid bump sound of the shuttlecock of feather returns player place, gives the feedback information of their technical elements about hitting position on racket and shot.This part is owing to feather material, part are because the radial position of each feather and the rigidity that the feather bar provides.

An injection-molded skirt section is adopted in the design of most of artificial feather balls.The hollow structure of nature feather bar provides very high strength-weight ratio, and adopts the solid section of existing injection-molded design not reach.Patent application GB2263412A shows the skeleton ribbed structure in a kind of support one film skirt section, and its main purpose is the rotary speed of the fin of support helix shape with the increase shuttlecock.Do not increase rigidity with this structure, the thickness of rib and/or film will have to reduce the degree that (in order to compare with the skirt section weight of feather) damages under bump and high-speed cruising to the skirt section.Patent GB1542497 shows a kind of shuttlecock, and it has the skirt section of the folded membrane structure in two top layers, yet the folded structure of rule can not cause that the flight characteristics to shuttlecock is basic flight rotation, and total performance is unacceptable.With the contacting of the rope yarn of racket the time, the firm peak value of this structure will provide the reaction very inequality with the shuttlecock of feather.To adopt very thin material for weight is remained within the specification requirement, and the production technology of reality can not reach specification requirement.There is the same fact in UK Patent Application GB2283687A, and it shows a kind of shuttlecock, and it has the skirt section of being made by corrugated plating and reinforcing band.

Although the nose radicals by which characters are arranged in traditional Chinese dictionaries of shuttlecock are impacted earlier, the skirt section is rolled on the racket face, speaks approvingly of according to the player, can cause sensorial difference between the different shuttlecocks.Exquisiteness contact that the shuttlecock of nature feather produces and reaction are not also understood by the designer of artificial feather ball and/or are adopted.The ring-type of the shuttlecock of feather bar and natural feather connects and composes a very light rigidity cone, some distortion a little when bump, awing can not damage, and the feather of the projection that overlaps provides rotation and initial contacting with the soft of racket face awing, then when shuttlecock leaves racket, knock-on reaction being arranged a little, this on the lenient side " contact " square stance can see.

The present invention tries hard to solve the problem in the prior art, and tries hard to simplify fabrication schedule and make cost keep minimum.

According to the present invention, a kind of shuttlecock is provided, it is made of a nose portion and a taper type skirt section that is contained in above it, the skirt section is made by the internal layer and the skin that stick together mutually usually, one deck in wherein two-layer is made to have some isolatedly towards the long chamber of another layer open, and forms the rigid column of the hollow with internal layer; Wherein Chang rigid member is placed in the rigid column of hollow.

According to further aspect of the present invention, a kind of shuttlecock is provided, it is made of the skirt section of the taper type of a nose portion and a top loading, and wherein nose portion makes and has an axially extending bore as air duct.

Embodiments of the invention are described below with reference to accompanying drawings:

Fig. 2 is the partial sectional view of shuttlecock skirt section perpendicular to the plane of feather ball journal;

Fig. 3 is the partial enlarged drawing on the axial plane of shuttlecock skirt section;

Fig. 4 is the nose portion of shuttlecock modification and the axial section in part skirt section;

Fig. 5 is the further nose portion of revising of shuttlecock and the axial section in part skirt section;

Fig. 6 is another nose portion of revising of shuttlecock and the axial section in part skirt section;

Fig. 7 is the nose portion of shuttlecock shown in Figure 6 and the plan view in part skirt section;

Fig. 1 represents a shuttlecock, and it comprises traditional rounded nose head 2 and the taper type skirt section 3 that is fixed on above it.As shown in the figure, nose portion is a hollow, and the skirt section is fixed by the device of a fixed disk 4.(not shown) nose portion can be solid in another embodiment, and it has one and admits the groove of lower end, skirt section.

The skirt section is matched to conical internal layer 5 and outer 6 by plastic plate and makes.As shown in Figure 2, outer 6 make the long chamber 8 with some intervals, open towards internal layer 5; Internal layer 5 is similar with it, has the long chamber 9 at some intervals, grow chamber 9 corresponding to and aim at outer chamber 8, and open towards layer 6.Chamber 8,9 coacts and forms the rigid column 10 of

hollow.Ectonexine

5,6 usefulness bonding agents and so on stick together mutually.Ectonexine is preferably on the whole mating surface and all sticks together.(not shown) only has one deck to have long chamber in another embodiment.These long chambeies no longer form the hollow rigid post with other laminated work.

Long rigid member 11 is positioned at hollow posts 10, and bonds to bonding agent and so on the

surface layer

5,6 in skirt section 3.Shown in the amplifier section of Fig. 2, this rigid member is a hollow tube.Also can provide the rigid member of solid foaming in addition, as the member of the plastics of foaming.The rib part of rigid column 10 imitation feather system shuttlecocks, and can have sidepiece parallel or oblique cone.Rigid member 10 helps to prevent the skirt section parting, and can increase the globality in the rigidity of structure and skirt section greatly.

As shown in Figure 1, hollow posts 10 roughly reaches the free edge 14 in skirt section from nose portion.In this case, the length of rigid member 11 will be similar to or be less than slightly the length of rigid column 10.

In distortion shown in Figure 2, rigid column 10 and rigid member 11 reach from skirt section free edge 14 from nose has one to be the position of distance, the outside in the skirt section, and be inverted in the chamber 9 of internal layer 5, and they are enclosed within on the corresponding chamber 8 of skin 6 like this.In another embodiment (not shown), outer 6 chamber 8 is inverted.

Because post 10 has and the similar width of the rib of the used feather of traditional shuttle part, their allow to have roomy space on plane, skirt section between them, the moulding of the form device that is used to fly.Between typical each post 10 its plane space from the end of nose portion be post 10 width in that 3-5 doubly or more more.Flight form device comprises that processing imitates the through hole 15 of opening of the same position of shuttlecock of feather between post 10.On the skin 6 in the skirt section 3 of each post 10, cut out pin-joint piece 16.Sheet 16 is 17 hinged along the edge, and is outstanding from the skirt section cone slightly when loosening, and with the feather of the shuttlecock of imitation feather, and shuttlecock rotated awing.When high-speed flight, the air space behind the sheet is closed, and slice, thin piece has and pushes away flat tendency.On the internal layer behind the sheet 16 5, also has opening 18.

If desired, the circumferencial direction on plane can also provide enhancing rib (not shown) between post 10.

In order to imitate the shuttlecock of feather, internal layer and/or outer 5,6 also can be processed with the slit (not shown).Otch stretches a short distance from skirt section free edge 14 towards nose portion between post 10.

For the further shuttlecock of imitation feather, skirt surface can be topped at least in part the material of crystalline or wire.

In order to gain in strength and/or to produce acoustic damping, the one deck in skirt section or two-layer can making by the laminated product of two or more materials as plastic foil and fiber.This laminated product has increased the life-span of shuttlecock, and situation about tearing to shreds with stressed breakage that reduce to use that monolayer material may occur takes place.

In the shuttlecock of feather, adopt 16 feathers.Here shown shuttlecock has 14 posts and 14 planes between them, and this numeral can increase or reduce on demand.By the shuttlecock that provides to be less than 16 posts, the planar dimension between the post of the form device configuration that can be used for flying has increased.

The nose portion of the remodeling of Fig. 4-6 expression shuttlecock.In each case, nose portion all has the axial hole 20 as air duct.In Fig. 5, inner variable plug-in unit 21 is fixed in the hole to control the passage of air.In Fig. 6 and 7, the hole has column part 201 and frustum part 202.An adjustable rotatable cover 22 is positioned in the hole, with the control air duct.

If hole 20 and plug-in unit or lid are provided, just can control air-flow by shuttlecock nose portion, therefore can reduce the weight of shuttlecock, improve its flight characteristics.
