Description

Technical Field

[0001] This utility model relates to the field of badminton manufacturing technology, and in particular to an artificial feather and a badminton shuttlecock. Background Technology

[0002] The main sources of natural feathers currently available include goose feathers, partridge feathers, guinea pig feathers, cherry duck feathers, and mallard feathers. Each goose or duck that produces feathers has only 4-6 feathers that can be made into high-end feathers, while the other feathers are gradually reduced due to reasons such as bending, asymmetry, and breakage, and are used to make other low-end feathers.

[0003] In the current process of producing badminton shuttlecocks from natural feathers, the feathers undergo multiple processes such as rinsing, drying, feather selection, and cutting. It takes more than a month for the feathers to go from entering the factory to being made into a shuttlecock. The entire production process not only pollutes the environment, but also involves cumbersome procedures and an excessively long production cycle. Due to the inherent characteristics of natural feathers, shuttlecocks made from them are far less durable than those made from artificial feathers.

[0004] Currently, due to the different shapes and sizes of existing natural feathers (affected by the size and shape of the feathers themselves), the shuttlecocks made from them have different flight speeds. In some high-altitude and low-pressure areas of my country, there are situations where "there are no shuttlecocks to play with". Therefore, this application provides an artificial feather and a shuttlecock to meet the needs. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an artificial feather to solve the problem of the difference in flight speed of badminton shuttlecocks caused by the different shapes and sizes of existing natural feathers.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] An artificial feather includes: a feather body comprising: a first feather and a second feather; a feather shaft disposed between the first and second feathers, and located on the longitudinal center lines of the first and second feathers; the feather shaft being generally frustoconical in shape, with an upper radius smaller than a lower radius, and the end of the feather shaft away from the feather body being conical; the first and second feathers being bonded together by adhesive, the adhesive application amount of the first feather being 30 g / m² and the adhesive application amount of the second feather being 10 g / m²; and a plurality of through holes disposed on the first and second feathers, with the two feathers being in the same position, for adjusting their turbulence performance.

[0008] When the first feather is positioned to fit against the second feather, the first feather is located on the front side.

[0009] The feather shaft is made of hollow modified composite fiber rod or solid rod with a diameter of 0.15mm.

[0010] The feather body is made of ultra-light resin film or modified polyolefin material.

[0011] The feather shaft is provided with a coating layer, which includes a visual layer and an anti-slip layer. The visual layer covers the feather shaft and is used to change the color of the feather shaft. The anti-slip layer is located at 1 / 2 of the length of the feather shaft and is used to increase the friction between the hook line and the feather shaft.

[0012] The feather shaft is configured such that the end near the first feather is convex, and the end near the second feather is smooth.

[0013] A badminton shuttlecock comprising a ball and any one of the aforementioned artificial feathers, the artificial feathers being mounted on the ball.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] In the above solution, by reasonably setting the material, appearance, and material, thickness, and density of the feather shaft, the total weight of a single artificial feather is precisely controlled within a suitable range, making it consistent with the weight of natural feathers. This not only solves the problem of inconsistent natural feathers due to their variety, but also improves the problem of deviation in the stringing process of badminton shuttlecock production caused by the string slipping due to the excessively thin diameter of artificial feathers and feather shafts and material differences.

[0016] By setting several through holes, the turbulence performance can be adjusted, thereby reducing the impact of aerodynamics on the shuttlecock itself during flight. As a result, the shuttlecock made of artificial feathers is closer to the shuttlecock made of natural feathers in terms of flight status and feel. Attached Figure Description

[0021] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of this utility model. However, this is only for illustrative purposes and is not intended to limit this utility model to the specific structure, device and environment. According to specific needs, those skilled in the art can adjust or modify these devices and environments, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0022] The artificial feather and badminton shuttlecock provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can also use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0023] like Figure 1 - Figure 2 As shown, an embodiment of this utility model provides an artificial feather, comprising: a feather body 1, the feather body 1 including: a first feather 11 and a second feather 12; a feather shaft 3, disposed between the first feather 11 and the second feather 12, and located on the longitudinal center line of the first feather 11 and the longitudinal center line of the second feather 12; the feather shaft 3 is generally frustoconical in shape, with the upper radius smaller than the lower radius, and the end of the feather shaft 3 away from the feather body 1 is conical; the first feather 11 and the second feather 12 are bonded together by adhesive coating, the amount of adhesive coating on the first feather 11 is 30g / ㎡, and the amount of adhesive coating on the second feather 12 is 10g / ㎡; a plurality of through holes 2 are disposed on the first feather 11 and the second feather 12, and the two are in the same position, for adjusting their turbulence performance.

[0024] By setting through holes 2, the number (quantity and shape) of through holes 2 can be selected according to actual needs. Through holes 2 can be set in different shapes. For example, through holes 2 can be designed as circles, which are easy to process and can provide a uniform airflow distribution; they can be designed as ellipses, which can adjust the airflow in different directions and help to fine-tune the flight characteristics of the shuttlecock; they can be designed as polygons such as hexagons, octagons, etc., which can be used to increase or decrease air resistance in specific directions and are suitable for situations that require precise control of airflow. When the artificial feather moves in the air, the air will pass through or around these through holes 2. According to the position, size and distribution of the holes, the airflow pattern through the feather surface can be adjusted. At the same time, through holes 2 can help break the laminar boundary layer formed on the original smooth surface and promote the formation of turbulence. This change can increase the frictional resistance in the local area, thereby improving the airflow conditions around the entire structure and achieving the purpose of optimizing flight characteristics. By applying appropriate amount of glue and bonding method, the connection strength between the feather pieces can be enhanced. A larger amount of glue on the side of the first feather piece 11 helps to better fill the gaps between the feather pieces during the pressing process, making the two bond more tightly.

[0025] The first feather 11 is positioned at the front after being attached to the second feather 12. The combined weight of the first feather 11 and the second feather 12 is 0.025-0.04g. By controlling the combined weight of the first feather 11 and the second feather 12 within a suitable range and coordinating it with the selected feather shaft 3, the total weight of a single artificial feather is ultimately achieved to be 0.125-0.145g, thus matching the weight of a natural feather and ensuring its precision.

[0026] The feather shaft 3 is made of hollow modified composite fiber rod or solid rod with a diameter of 0.15mm. The weight of the feather shaft 3 is 0.08-0.11g. By setting the material of the feather shaft 3, it has suitable strength and toughness, which can ensure that the feather shaft 3 will not easily break during the use of badminton, thus improving the durability of the badminton. At the same time, it can withstand the process of gluing and pressing without deformation during the production process.

[0027] The feather body 1 is made of ultra-light resin film or modified polyolefin material. The thickness of the feather body 1 is 0.35 mm, and the density of the feather body 1 is 35-40 kg / m³. 3 By setting the material type of the feather body 1, the problem of inconsistent consistency of natural feathers due to different types is solved, avoiding inconsistencies in the flight performance and feel of the shuttlecock due to weight differences. At the same time, the material has good flexibility and plasticity. During the production of the feather body, it can be tightly combined with the feather shaft 3 through processes such as gluing and pressing, and present a suitable shape. In addition, it can better withstand external forces during the use of the shuttlecock, is not easy to break, and improves the durability of the shuttlecock.

[0028] A coating layer is applied to the feather shaft 3, comprising a visual layer and an anti-slip layer. The visual layer covers the feather shaft 3 and alters its color. The anti-slip layer is positioned at half the length of the feather shaft 3 to increase friction between the string and the shaft. The visual layer transforms the entire feather shaft 3 into a pure white surface, enhancing its visibility and allowing the shuttlecock to be quickly spotted during high-speed flight. The anti-slip layer, applied primarily at the halfway point of the string during shuttlecock production, increases friction between the string and the shaft, securing the string in place. The anti-slip layer utilizes a special coating or paint with a high coefficient of friction, such as a coating containing silicone particles, a rubber-based coating, or a roughened surface material.

[0029] The feather shaft 3 is designed with a raised end near the first feather piece 11 and a smooth end near the second feather piece 12. The first feather piece 11 has a larger amount of adhesive applied, and the raised end of the feather shaft 3 near the first feather piece 11 during pressing helps to better fix the position of the feather piece, enhances structural stability, and makes the appearance closer to that of natural feathers.

[0030] A badminton shuttlecock comprising a ball and any one of the aforementioned artificial feathers, the artificial feathers being mounted on the ball.

[0031] The technical solution provided by this utility model first sprays the surface of the feather shaft 3 to make the entire feather shaft 3 pure white. Anti-slip material is sprayed at the two hook positions at 1 / 2 during the production of badminton shuttlecocks. The first feather piece 11 is coated with glue at a glue amount of 30g / ㎡, and the second feather piece 12 is coated with glue at a glue amount of 10g / ㎡. The smaller radius end of the feather shaft 3 is placed between the first feather piece 11 and the second feather piece 12, located on the longitudinal center line of the two, so that the first feather piece 11 and the second feather piece 12 are attached. After being attached, the first feather piece 11 faces upward, and the first feather piece 11 and the second feather piece 12 are pressed together by a rubber roller. After pressing, the feather shaft 3 near the first feather piece 11 is convex, and the feather shaft 3 near the second feather piece 12 is smooth. After the feather pieces are attached, they pass through a pressing roller with a herringbone diagonal pattern, so that the surface of the feather pieces will have a diagonal pattern appearance similar to that of natural feathers.
