Description

TECHNICAL FIELD

[0001] The utility model relates to the badminton technical field especially light weight artificial feather and badminton of resistance to play. BACKGROUND

[0002] Badminton is a popular ball game, and people's playing experience is closely related to the quality of badminton. Good badminton usually needs to have high flight stability and resistance to play. Since the processing cost of natural feather is high, people designed artificial feather for making badminton. The key factor that determines the flight stability of artificial badminton is the weight of artificial feather. Too light or too heavy is not conducive to the badminton to maintain a certain flight trajectory in the air.

[0003] At the same time, improving the resistance to play often means using a certain strength of material, making the whole more solid, for example, using reinforced fiber to make badminton, but this will increase the weight of badminton, which is not conducive to improving its flight stability, and the toughness of the feather will decrease, which is easy to be broken after receiving external force.

[0004] For example, Chinese invention patent CN117861179A discloses a badminton, comprising: a base body; and a plurality of artificial feathers connected with the base body, the artificial feather comprising a feather part and a shaft connected with the feather part, the shaft comprising a web extending along a first direction in which the shaft extends, a first flange extending from one end of the web in a second direction orthogonal to the first direction, and a second flange extending from the other end of the web in the second direction along a third direction orthogonal to the second direction, the shape of the cross section orthogonal to the extension direction of the shaft, i.e. the first direction, is I-shaped, so that it has a certain toughness, and at the same time the shaft does not contain reinforced fiber, so that the shaft is not easy to break, for example, composed of block polypropylene. The strength of such artificial feather is limited and not resistant to play.

[0005] For example, Chinese utility model patent CN204485251U discloses a carbon fiber artificial feather for badminton, comprising a feather shaft and a feather leaf formed at the end of the feather shaft, the feather shaft is composed of a feather shaft body and a core, the core is located inside the feather shaft body and extends along the length direction of the feather shaft body, the core material is synthetic fiber material or resin material, the feather shaft body material is carbon fiber reinforced resin material, the feather leaf is located at the end of the upper bottom surface of the feather shaft body, and the plane where the feather leaf is located is parallel to or coincides with the first side surface of the feather shaft body. This scheme reduces the specific gravity of carbon fiber reinforced resin material by setting the core, realizes the reduction of feather weight, and adds synthetic fiber material or resin material to increase the toughness of the feather shaft, but the feather leaf is easy to damage and the flight stability is not durable.

[0031] Example 1:

[0032] Reference Figures 1-7 The artificial feather 20 provided in the embodiment mainly comprises a shaft 210 and a feather part 220, Figure 2 It is a front end view, that is, the free end of the feather part 220 is regarded as the front end, and the tail part of the shaft 210 is regarded as the front end, and the shaft 210 can be seen supporting the feather part 220.

[0033] The shaft 210 comprises a carbon fiber hollow tube, and the shaft 210 has a feather joint part 211 and a handle part 212 connected with the feather joint part 211. The carbon fiber hollow tube can not only reduce the weight of the artificial feather, but also provide certain strength, and the hollow part can provide certain toughness for force buffering after being stressed.

[0034] Preferably, the carbon fiber hollow tube of the shaft 210 can be partially or entirely filled with foaming material, which can provide the lightweight effect of the shaft 210, and the outer layer of carbon fiber can provide certain hardness to achieve the effect of natural feather shaft.

[0035] In other embodiments, the shaft 210 is a carbon fiber hollow tube with gradually changing pipe diameter from the handle part 212 to the feather joint part 211, which can match the feather part 220 to achieve balanced weight distribution and improve flight stability.

[0036] Reference Figure 3 and Figure 4 The components constituting the feather portion 220 include a plurality of feather branches 221, which are fixed to the feather joint portion 211, and the feather joint portion 211 has opposite first and second side surfaces 211a and 211b.

[0037] The first side surface 211a is inwardly recessed to form one or more first recessed portions 2111 for insertion of the feather branches 221, and the second side surface 211b is inwardly recessed to form one or more second recessed portions 2112 for insertion of the feather branches 221. The fixation of the feather portion 220 to the quill shaft 210 is achieved by inserting the plurality of feather branches 221 into the recessed side surfaces, which has a good fixation effect. Even if a small number of feather branches 221 are deformed by impact during flapping, the overall connection stability of the feather portion 220 and the quill shaft 210 is high, and the flight stability of the artificial feather is maintained.

[0038] In the present embodiment, the first side surface 211a is inwardly recessed to form a continuous first recessed portion 2111, as shown in Figure 1 、 Figure 3 、 Figure 4 which starts at the junction of the handle portion 212 and the feather joint portion 211 and ends at the extension end of the feather joint portion 211, and a plurality of feather branches 221 can be inserted and fixed in the first recessed portion 2111; the second recessed portion 2112 is located on the second side surface 211b and is symmetrically arranged with the first recessed portion 2111.

[0039] In particular, as shown in Figure 5 , the first recessed portion 2111 and the second recessed portion 2112 can be configured to facilitate the engagement of the feather branches 221, so as to facilitate the insertion and fixation of the feather branches 221. For example, the first recessed portion 2111 and the second recessed portion 2112 are continuous grooves, and the feather branches 221 are inserted into the grooves in a row and fixed by adhesive.

[0040] For another example, as shown in Figure 6 , a slot hole is provided in the first recessed portion 2111 to facilitate the direct insertion and fixation of the feather branches 221. Preferably, the width of the first recessed portion 2111 is adapted to the cross-sectional width of the feather branches 221, etc.

[0041] As shown in Figure 7 , the present embodiment provides an artificial shuttlecock, which includes a ball head 10 and a plurality of artificial feathers 20 connected to the ball head 10.

[0042] It is worth noting that for the first recess 2111 and the second recess 2112 of the present embodiment, the adhesive can be selected to be directly coated into the first recess 2111 and the second recess 2112, and then the vane branch 221 is implanted into the recesses, so as to fix the vane branch 221 with the vane joint 211, thereby improving the stability of the vane 220. However, the fixation of the vane branch 221 is not limited to the bonding mode, but can also be the engagement or buckling mode.

[0043] Embodiment 2:

[0044] The present embodiment optimizes the vane on the basis of embodiment 1, and the vane branches 221 are preferably fixed on the vane shaft 210 in a parallel manner. In some preferred embodiments, the vane branches 221 are respectively bonded to the vane joint 220 in a direction at a preset included angle a with the vane shaft 210, and the included angle a is ≤ 90°. In particular, in order to make the wind resistance of the artificial feather smaller during flight and more in line with the flight form of natural feathers, the included angle a between the vane branches 221 and the vane shaft 210 is 30°-60°. The included angle a may, for example, be 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc., but is not limited to the listed values. Other unlisted values within the range of the values are also applicable. More preferably, the included angle a is 40°-50°.

[0045] In the present embodiment, the vane branch 221 is a wire, and the material of the wire is selected from any one or a combination of at least two of polyamide fibers, polyolefin fibers, acrylic fibers, and polyester fibers. The cross section of the wire can be circular, rectangular, square, polygonal, etc. For example, the cross section of the wire is circular, the cross section diameter of the wire is 0.05-0.5 mm, and the cross section diameter of the wire may, for example, be 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5 mm, etc., but is not limited to the listed values. Other unlisted values within the range of the values are also applicable. Preferably, the cross section diameter of the wire is 0.08-0.3 mm, so that the vane 220 is lighter and has better overall aerodynamic performance during flight. In a preferred embodiment, the cross section of the vane branch 221 gradually decreases along the extension direction thereof. For example, the vane branch 211 is a kind of frustum structure, including a first root connected with the vane joint 220, and the vane branch 211 of the frustum structure gradually tapers from the first root to the tip.

[0046] Further reference is made to Figure 8As shown, each feather branch 221 has two opposite sides, and the feather branch 221 has fine branch parts 222 in the same plane as the feather branch 221 and in a direction different from the extension direction of the feather branch 221. The fine branch parts 222 are in the same plane as the feather branch 221, which is conducive to reducing air resistance, and at the same time, the fine branch parts 222 sufficiently fill the gap between adjacent feather branches 221 to avoid a large amount of airflow flowing between the gaps of the feather branches 221, so that the overall aerodynamic performance of the feather part 220 is better during flight. In this embodiment, each feather branch 221 has two opposite sides, and the fine branch parts 222 are respectively planted on the two opposite sides. In other embodiments, the fine branch parts 222 can all be planted on the same side. It can be adaptively adjusted according to the actual process needs. However, it should be noted that, relatively speaking, the setting mode of the fine branch parts 222 on each feather branch 221 included in each feather part 220 is preferably in a unified manner, for example, in a shuttlecock, the fine branch parts 222 on each feather branch 221 are all set in a double-sided manner, or all set in a single-sided manner, but a mixed manner is not excluded.

[0047] In a preferred embodiment, the fine branch parts 222 on each feather branch 221 are set in a double-sided manner, referring to Figure 8The thin branch parts 222 on opposite sides are comb tooth structures, and the tooth parts of the comb tooth structures are embedded into the gaps of the opposite tooth structures, so that the airflow is prevented from flowing between the gaps of the feather branches 221, and the overall aerodynamic performance of the feather part 220 is better during flight. In the embodiment, the thin branch parts 222 are filaments, and the material of the filaments is selected from any one or a combination of at least two of polyamide fibers, polyolefin fibers, acrylic fibers, and polyester fibers. The cross section of the filament can be circular, rectangular, square, polygonal, etc. Preferably, the cross section of the filament is circular, and the cross section diameter of the filament is 0.03-0.5 mm, for example, 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5 mm, etc., but is not limited to the listed values, and other unlisted values in the range are also applicable. Notably, the cross-sectional area of the filament is preferably smaller than that of the wire of the feather branches 221. For example, the cross section of the filament is circular, and the cross section diameter of the filament is 0.03-0.3 mm, more preferably 0.03-0.2 mm. In a preferred embodiment, the cross section of the thin branch part 222 gradually decreases along the extension direction thereof. For example, the thin branch part 222 is a conical structure, including a second root connected to the feather branches 221, and the thin branch part 222 of the conical structure gradually decreases from the second root to the tip. More preferably, the thin branch part 222 is a flat structure, and the cross section gradually decreases along the extension direction thereof, so as to reduce the wind resistance on the side. For example, the flat structure can be elliptical, etc. In particular, the flat structure can have a thickness that gradually decreases from the middle to both sides, or gradually decreases in the direction away from the feather shaft 210, so as to further reduce the wind resistance and improve the flight effect.

[0048] In some preferred embodiments, the two ends of the thin branch part 222 are fixed on the adjacent two feather branches 221, so that the overall integrity of the entire feather part 220 is stronger, the flexibility and stability are considered, and the impact resistance is improved.

[0049] Although the embodiments of the utility model have been shown and described above, it should be understood that the above embodiments are exemplary and cannot be understood as limiting the utility model. Those skilled in the art can change, modify, replace and modify the above embodiments within the scope of the utility model without departing from the principles and purposes of the utility model.
