Description

Technical Field

[0001] This application relates to the construction of badminton shuttlecocks, and in particular to the artificial feathers of badminton shuttlecocks. Background Technology

[0002] The structure of a badminton shuttlecock can be basically divided into two main parts: the "head" and the "feathers". The head is a cylinder with a semi-spherical front end, which is the part where the shuttlecock and the racket face come into contact. The racket face is a net surface made of special strings crisscrossed. The feathers are evenly inserted at the end of the head and neatly arranged in a cone-shaped structure. The current standard for badminton shuttlecocks uses 16 feathers.

[0003] Based on the materials used in their manufacture, badminton shuttlecocks can be broadly categorized into two types: natural and synthetic. Shuttlecocks made from natural materials are generally more expensive than those made from synthetic materials. Therefore, shuttlecocks made from natural feathers are mostly used in competitions, while those made from synthetic materials are often used as practice shuttlecocks for beginners.

[0004] Natural feathers are typically made from goose or duck feathers, and their cost is high due to the difficulty in collecting, preparing, and processing them. During matches, even slight wear and tear on the shuttlecock's feathers can affect its trajectory, necessitating immediate replacement. This results in a consistently high consumption of shuttlecocks during intense matches.

[0005] In the approved Taiwanese invention patent (certificate number TW I713740) entitled "Artificial Feathers for Badminton and Badminton Shuttlecock," the feathers of the proposed artificial feathers can be constructed using materials such as nonwoven fabric or resin. When using nonwoven fabric, a reinforcing film is formed on the surface to prevent the fibers of the nonwoven fabric from unraveling during impact. This reinforcing film can be formed by coating with resin.

[0006] The approved Taiwanese invention patent (certificate number TW I636815) for "Badminton Shuttlecock and its Shaft" describes a shuttlecock comprising multiple feathers, a head, and multiple shafts. Each shaft includes: a shaft body with a feather end and a head end, made of plastic material, with one of the feathers attached to the feather end. The shaft body further includes: a hollow tube with an upper and lower surface; a receiving channel located within the hollow tube; a pair of side wings connected to opposite sides of the hollow tube, the side wings being sheet-like structures that securely attach the feathers to them; and a foam material filling the receiving channel. Filling the shaft body with foam material mimics the porous structure of natural feathers, resulting in a lightweight and low-density shaft while maintaining impact resistance and toughness. Summary of the Invention

[0038] The artificial feathers for badminton shuttlecocks proposed in this application are made from a thermoplastic composite material containing artificial fibers, and then manufactured using microfoam injection molding technology (MuCell) and have microbubble B (see...). Figure 4 The integrally molded structure is also a micro-elastic porous structure with microbubbles; the thermoplastic composite material containing artificial fibers comprises: 80% to 90% by weight of nylon (polyamide, commonly known as nylon, English name Polyamide, abbreviated as PA), and 10% to 20% by weight of artificial fibers. A preferred embodiment of the artificial fibers includes either glass fiber or carbon fiber. By controlling the density of the microbubbles, its elasticity, density, and weight can be adjusted to achieve the toughness and elasticity required for badminton feathers and meet the weight standards for badminton shuttlecocks.

[0039] Please see Figure 1 This is a structural diagram of a preferred embodiment of the artificial feathers for badminton shuttlecocks according to this application. The preferred embodiment of the artificial feathers for badminton shuttlecocks according to this application includes: a main shaft 10, a first feather groove 21, a first feather vane 31, and a second feather vane 32.

[0040] The cross-sectional shape of the main shaft 10 is wedge-shaped (see...). Figure 4The wedge shape includes a left side 4L, a right side 4R, a top surface 4U, and a back surface 4B. The main shaft 10 is constructed by connecting the rachis 11 and the root 12 coaxially. Since the artificial feathers of this application are made using microcellular injection molding technology (MuCell), in a preferred embodiment, the rachis 11 and the root 12 are connected end-to-end coaxially to form the main shaft 10. In a preferred embodiment, the width W1 of the main shaft 10 gradually narrows from the root 12 towards the rachis 11 (see...). Figure 2 Since the cross-sectional shape of the main shaft 10 is wedge-shaped, the width W1 of the main shaft 10 can be understood as including the width of the back surface 4B and the top surface 4U of the main shaft 10, both of which gradually narrow in the direction extending from the feather root 12 to the feather shaft 11, and the thickness T1 of the main shaft 10 gradually thins in the direction extending from the feather root 12 to the feather shaft 11 (see...). Figure 3 and Figure 4 In a preferred embodiment, the axial ends of the main shaft 10 are slightly warped towards the rear surface 4B to form a warped arc shape (see...). Figure 3 ).

[0041] The first quill groove 21 is located at least at one of the top surface 4U and the back surface 4B of the main shaft 10, and the first quill groove 21 extends along the axial direction of the main shaft 10. In a first preferred embodiment, the first quill groove 21 is disposed on the top surface 4U of the main shaft 10 (see...). Figure 1 and Figure 4 In another preferred embodiment, a second fin 22 is included (see...). Figure 6 The first feather groove 21 is located on the top surface 4U of the main shaft 10 and extends along the axial direction of the main shaft 10; the second feather groove 22 is located on the back surface 4B of the main shaft 10 and extends along the axial direction of the main shaft 10.

[0042] The first vane 31 and the second vane 32 are respectively positioned on the left side 4L and the right side 4R of the rachis 11 and are connected to the rachis 11 as a single unit (see...). Figure 1 and Figure 5 The first vane 31 and the second vane 32 are symmetrical in construction; however, the projected shapes of the first vane 31 and the second vane 32 on the same plane are generally asymmetrical. The first vane 31 and the second vane 32 are constructed by: a plurality of parallel and spaced-apart barbs 33, with a membrane 34 between any two adjacent barbs 33, one end of each barb 33 being connected to the rachis 11, and the other end of each barb 33 extending in a direction away from the rachis 11, and the inner edge 341 of the membrane 34 being connected to the rachis 11.

[0043] In a preferred embodiment, the cross-sectional shape of the barb 33 is arc-shaped or semi-circular (see...). Figure 1This provides better structural strength to the barb 33, and the arc shape further reduces the weight of the barb 33, thus helping to control the weight of the shuttlecock within a standard range. In a preferred embodiment, the thickness T2 of the first vane 31 and the second vane 32 gradually decreases from the rachis 11 toward the direction away from the rachis 11 (see...). Figure 5 ).

Any person skilled in the art may make some modifications or alterations to other equivalent embodiments without departing from the scope of the technical means disclosed in this application, but these should still be regarded as the technology or embodiments that are substantially the same as those of this application.
