Description

Technical Field

[0001] This utility model belongs to the field of sporting goods, specifically relating to a badminton shuttlecock assembled with feather leaves. Background Technology

[0002] Badminton is a sport enjoyed by many. Players use badminton rackets to hit shuttlecocks back and forth to achieve the purpose of the sport.

[0003] There are currently two types of badminton shuttlecocks:

[0004] The first type is the traditional badminton shuttlecock, which involves applying glue to the tips of real feathers such as goose feathers or duck feathers and inserting them circumferentially into the back end of the shuttlecock head. Then, a rope is used to cross around the middle of the length of the real feathers, and glue is used to improve the stability of the real feathers in place.

[0005] The second type is injection-molded badminton shuttlecock, which can be referred to as the badminton shuttlecock disclosed in Chinese Patent No. CN200880105044.3. The feather body is formed as a whole by injection molding, and the shuttlecock is formed by installing the feather body and the head. In order to improve the stability of flight, the structure of the feather body is set with a ring grid structure on the side away from the head.

[0006] The problem with the first type of shuttlecock is that it requires real feathers, which leads to excessively high production costs. The problem with the second type of shuttlecock is that its one-piece molded body has less flight resistance, resulting in a poorer simulation of the first type of shuttlecock and affecting the user experience. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a feather-assembly badminton shuttlecock that optimizes the hitting experience by simulating real feathers through the installation rod being inserted into the mounting cavity of the feather leaf.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A badminton shuttlecock with assembled feather blades includes: a shuttlecock head; a feather body support disposed on the shuttlecock head, the feather body support having multiple circumferentially arranged mounting rods disposed on the feather body support; feather blades, the number of feather blades being multiple, each feather blade including a first blade and a second blade that fit together, a mounting cavity being provided between the first blade and the second blade, the mounting cavity for the insertion of the mounting rods; the feather blades and the mounting rods being fixedly disposed.

[0010] The present invention is further configured such that the first blade and / or the second blade are made of Oxford cloth or non-woven fabric.

[0011] The present invention is further configured such that the number of the mounting rod and / or the feather blades is 8-18.

[0012] The present invention is further configured such that: the two ends of the length of the mounting cavity are respectively provided with an insertion opening for inserting the mounting rod and a positioning part for positioning the insertion of the mounting rod; and / or, the distance between the position of the feather blade furthest from the ball head and the mounting rod is s, wherein s≤5mm.

[0013] The present invention is further configured such that: the feather blade is provided with an edge positioning line on the outer periphery of the mounting cavity, and the edge positioning line fixes the first blade and the second blade together.

[0014] The present invention is further configured such that: the edge positioning line is formed by hot melting the first blade and / or the second blade; and / or, the edge positioning line includes a plurality of connecting units arranged at intervals along the length direction of the edge positioning line, the connecting units connecting the first blade and the second blade.

[0015] The present invention is further configured such that the edge positioning line is formed by ultrasonic hot pressing.

[0016] The present invention is further configured such that: the mounting rod is tapered in shape away from the ball head; and the mounting cavity is tapered in shape away from the ball head.

[0017] The present invention is further configured such that: the mounting rod and the feather blade are bonded together with adhesive; or, the mounting rod and the feather blade are fixedly connected by heat fusion of the mounting rod and / or the feather blade; or, the mounting rod is fixed by interference fit within the mounting cavity.

[0018] The present invention is further configured such that: the feather support is an integrally molded injection molded part, and the feather support is assembled on the ball head; or, the feather support and the ball head are integrally molded injection molded parts.

[0019] By adopting the above technical solution, the badminton shuttlecock formed by assembling the feather blades onto the mounting rod more closely simulates a shuttlecock made of real feathers, such as wind resistance, airflow guidance, and appearance, thus providing a better hitting experience. In addition, compared to shuttlecocks made of real feathers, shuttlecocks made of industrial materials are less expensive. Specifically, the feather blades are formed by bonding the first and second blades together to create a simulated shape, and an installation cavity is formed between the first and second blades.

[0039] To enable those skilled in the art to better understand this utility model and to more clearly define the scope of protection claimed by this utility model, the present utility model is described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present utility model, and the specific and direct descriptions of related structures are merely for the convenience of understanding the present utility model; the specific features do not necessarily or directly limit the scope of implementation of the present utility model. Conventional choices and substitutions made by those skilled in the art under the guidance of the present utility model should all be considered within the scope of protection claimed by this utility model.

[0040] like Figures 1-8 As shown, this utility model discloses a feather-leaf assembled badminton shuttlecock, comprising:

[0041] The ball head 1 has a hemispherical striking end 11 at its lower end and a flat assembly end 12 at its upper end.

[0042] Feather support 2 is located at assembly end 12, and multiple mounting rods 21 are arranged circumferentially on the upper end of feather support 2.

[0043] Feather blades 3, the number of feather blades 3 is the same as the number of mounting rods 21, so that feather blades 3 are set on each mounting rod 21 respectively.

[0044] Specifically, the feather blade 3 includes a first blade 31 and a second blade 32 that fit together, and an installation cavity 33 is provided between the first blade 31 and the second blade 32 so that the installation rod 21 can be assembled by inserting it into the installation cavity 33; and the feather blade 3 and the installation rod 21 are fixedly arranged.

[0045] Therefore, the shuttlecock formed by assembling the feather blades 3 onto the mounting rod 21 is closer to the simulation of a shuttlecock made of real feathers, such as the simulation of wind resistance, airflow guidance, and appearance shape, thus providing a better hitting experience. In addition, compared to shuttlecocks made of real feathers, shuttlecocks made of industrial materials are less expensive. Specifically, the feather blades 3 are formed by bonding the first blade 31 and the second blade 32 to form a simulated shape, and an mounting cavity 33 is formed between the first blade 31 and the second blade 32. The mounting rod 21 can be inserted into the mounting cavity 33 for assembly, which not only makes the assembly more convenient, but also improves the stability and assembly accuracy of the mounting rod 21 and the feather blades 3, thereby further optimizing the hitting experience.

[0046] Preferably, the first blade 31 and the second blade 32 are made of materials such as Oxford cloth or non-woven fabric to make the simulation of a badminton shuttlecock with real feathers closer to optimize the hitting experience.

[0047] The number of mounting rods 21 and feather blades 3 is preferably 8-18, and this embodiment uses 16 in order to optimize the hitting experience by using an appropriate number to more closely simulate a badminton shuttlecock with real feathers.

[0048] In this embodiment, the feather support 2 is an integrally molded injection molded part, and is assembled onto the shuttlecock head 1 through a snap-fit ​​structure 4. This simplifies the assembly process and reduces costs. The integrally molded feather support 2 also has better strength to improve the durability of the shuttlecock. In addition, the shuttlecock head 1 and the feather support 2 are connected by assembly, which allows the use of shuttlecock heads 1 made of different materials to optimize the hitting experience. Furthermore, the snap-fit ​​structure 4 makes the connection between the feather support 2 and the shuttlecock head 1 easy to install.

[0049] Specifically, the assembly end 12 of the ball head 1 is provided with an internal groove 13, and the lower end of the feather support 2 is integrally formed with a cylindrical mounting tube 23 to be inserted into the internal groove 13. The snap-fit ​​structure 4 includes a snap-fit ​​groove 41 provided on the peripheral wall of the internal groove 13 and a snap-fit ​​member 42 provided on the outer periphery of the mounting tube 23, so as to achieve fixed installation through the snap-fit ​​cooperation of the snap-fit ​​groove 41 and the snap-fit ​​member 42.

[0050] In other embodiments, the feather support 2 and the ball head 1 can also be integrally injection molded.

[0051] The mounting cavity 33 has an insertion opening 331 at the lower end for inserting the mounting rod 21, and a positioning part 332 at the upper end for positioning the mounting rod 21 during insertion.

[0052] Therefore, when the insertion opening 331 and the upper end of the mounting rod 21 are aligned, the feather blade 3 is placed downwards on the outer periphery of the mounting rod 21, and the positioning part 332 moves to the upper end of the mounting rod 21 to abut and position itself, thus ensuring the accuracy of the assembly.

[0053] Preferably, the distance between the furthest point of the feather blade 3 from the shuttlecock head 1 and the mounting rod 21 is s, where s≤5mm, so that the upper end of the mounting rod 21 is close to the top of the shuttlecock, thereby the mounting rod 21 effectively supports the relatively soft feather blade 3 and ensures the stability of the feather blade 3.

[0054] In this embodiment, s = 2mm is specifically used.

[0055] Preferably, in this embodiment, the first blade 31 includes an upper main body portion 311 and a lower extension portion 312. The main body portion 311 and the second blade 32 are the same in shape and size and are arranged in an overlapping manner. The mounting cavity 33 is disposed between the main body portion 311 and the second blade 32.

[0056] The structure formed by the main body 311 and the second blade 32 serves as the main feather blade 3 and simulates the physical properties of real feathers. It also forms an installation cavity 33 for the installation rod 21 to be inserted and installed. In addition, the extension 312 allows the support rod to be inserted into the installation cavity 33 more conveniently by first pressing against the extension 312 and then approaching the insertion opening 331, thus improving the ease of assembly.

[0057] Preferably, in this embodiment, the extension 312 and the mounting rod 21 are glued together, so that the mounting cavity 33 and the mounting rod 21 only need to be inserted. After the insertion is completed, the extension 312 is fixed by applying glue, so that the glue does not fill into the mounting cavity 33 with the mounting rod 21, thus avoiding the phenomenon of uneven glue during the movement of the mounting rod 21.

[0058] Preferably, the mounting rod 21 is interference-fitted into the mounting cavity 33 to form a first layer of fixation, and then the extension 312 and the mounting rod 21 are glued together to form a second layer of fixation, which improves the stability of the connection.

[0059] In other embodiments, adhesive can be applied to the outer periphery of the mounting rod 21, and then the mounting rod 21 can be inserted into the mounting cavity 33 to form an adhesive bond.

[0060] In other embodiments, the extension 312 and the mounting rod 21 are not glued together. Instead, after the mounting rod 21 is inserted into the mounting cavity 33, the mounting rod 21 and / or the feather blade 3 are fixedly connected by heat pressing, such as ultrasonic heat pressing.

[0061] The mounting rod 21 surrounds the central region 22, which is shaped to gradually widen upwards. The first blade 31 is located on the side of the mounting rod 21 away from the central region 22, and the second blade 32 is located on the side of the mounting rod 21 facing the central region 22.

[0062] Therefore, since the first blade 31 is located on the outside and the second blade 32 is located on the inside, the airflow during the shuttlecock's flight is as follows: Figure 3As shown, the airflow flows relative to the feather support 2 from the head 1 end. When flowing through the feather blade 3, the extension 312 will guide the airflow from the first blade 31 away from the second blade 32, so that the airflow will not enter the mounting cavity 33, thus preventing the airflow from entering the mounting cavity 33 and tearing the connection between the first blade 31 and the second blade 32, causing the feather blade 3 to fall off.

[0063] In this embodiment, the outer edges of the first blade 31 and the second blade 32 are provided with a hot-melt connection edge 34. Specifically, two raw material strips of different widths are bonded together and transported into the hot-cutting equipment. The hot-cutting equipment uses a heated annular punch with the same shape as the outer periphery of the first blade 31 to cut the stacked raw material strips so that while cutting off the first blade 31 and the second blade 32, the edges of the first blade 31 and the second blade 32 are hot-melt connected to form the hot-melt connection edge 34, making the processing more convenient.

[0064] Furthermore, in this embodiment, the feather blade 3 is provided with a U-shaped edge positioning line 35 on the outer periphery of the mounting cavity 33, so that one end is open to form an insertion opening 331 and the other end is closed to form a positioning part 332. The edge positioning line 35 also fixes the first blade 31 and the second blade 32 together. Specifically, the edge positioning line 35 is formed by ultrasonic hot pressing of the first blade 31 and the second blade 32, making processing more convenient and the structure simpler.

[0065] The edge positioning line 35 includes a plurality of connecting units 351 arranged at intervals along the length direction of the edge positioning line 35. The connecting units 351 connect the first blade 31 and the second blade 32, so that when the first blade 31 and the second blade 32 are thermally fused together through the gap between adjacent connecting units 351, there is an adaptive deformation space to prevent wrinkles from appearing on the edge positioning line 35.

[0066] Preferably, in this embodiment, the mounting rod 21 is shaped to gradually taper upwards; the mounting cavity 33 is shaped to gradually narrow upwards, so that the mounting rod 21 at the upper end of the shuttlecock is thinner and more easily deformed to mimic the effect of real feathers.

[0067] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
