Abstract
Description
Technical Field
[0001] This invention relates to the field of sports equipment technology, and in particular to a frisbee that is simple and stable. Background Technology
[0002] Frisbee (also known as flying saucer sport) is a simple yet challenging outdoor sport suitable for teams or individuals. However, while frisbee has many advantages, it also has some drawbacks:
[0003] (1) Frisbee game may seem simple, but it requires users to accurately control the flight trajectory, speed and angle of the frisbee. Therefore, the technical requirements of frisbee game are high. Generally speaking, beginners may encounter situations where the frisbee deviates from the target, lands too far or cannot be passed accurately.
[0004] (2) Although frisbee games do not require complicated equipment, they do require a certain space; specifically, frisbee games usually require an open space to throw and catch the frisbee.
[0005] (3) In the frisbee game, air (or wind) is the factor that determines whether the frisbee can fly stably (for example, strong winds or unstable wind speeds will cause the frisbee to fly unstably); if the frisbee flies unstably, it will affect the user's experience of the frisbee game.
[0006] (4) Traditional frisbees on the market are often made of hard plastic or cloth, which may cause cracks or deformation after strong impact or long-term use, thus affecting the flight of the traditional frisbee; among them, frisbees made of hard materials are more susceptible to external damage.
[0007] In the current market, users refer to a rotating disc as a frisbee; generally speaking, common frisbees are all one-piece molded structures.
[0008] In summary, traditional frisbees in the current technology still have the drawbacks of not being able to fly smoothly and stably enough, and being easily damaged upon impact. Summary of the Invention
[0009] The frisbee provided by this invention aims to solve at least some of the defects of existing frisbees.
[0010] This invention provides a frisbee. The frisbee includes:
[0011] Frisbee body; the frisbee body has an opening groove inside, and the end of the frisbee body away from the opening has a raised curved surface;
[0012] Three arc-shaped branches, resembling swallow wings, protrude from the raised surface and are evenly distributed on the raised surface.
[0013] The three arc-shaped branches form a rotationally symmetric structure, and the rotationally symmetric structure takes the center of the convex curved surface as the center of rotational symmetry.
[0014] In this configuration, one end of any of the arc-shaped branches extends to the edge of the raised surface, and the other end extends toward the center of the raised surface.
[0015] In some embodiments, the opening is located at the bottom of the frisbee body, and the groove has a preset groove depth;
[0016] When the frisbee is thrown, the groove reduces the air resistance between the air and the bottom of the frisbee body.
[0017] In some embodiments, the frisbee further includes:
[0018] A circular branch in the shape of a ring; the circular branch protrudes from the raised curved surface, and the circular branch is coaxially arranged with the main body of the flying disc;
[0019] In this configuration, one end of any of the arc-shaped branches that is away from the edge of the raised curved surface is connected to the outer ring surface of the circular branch.
[0020] In some embodiments, the frisbee further includes:
[0021] All three pedicles protrude from the raised surface and are evenly distributed on the raised surface;
[0022] The three crescent-shaped branches can form the rotationally symmetric structure.
[0023] In some embodiments, the circular branch, the three arc-shaped branches, and the three crescent-shaped branches are all integrally formed with the main body of the frisbee.
[0024] In some embodiments, there is a preset region between two adjacent arc-shaped branches, and each crescent-shaped branch is located within the preset region;
[0025] Each of the crescent-shaped branches can divide the preset area to form a first flow channel and a second flow channel, and the surface area of the first flow channel projected on the convex curved surface is smaller than the surface area of the second flow channel projected on the convex curved surface.
[0026] In some embodiments, after the frisbee is thrown, air flows over the bottom of the frisbee body at a first flow rate, over the surface of the arc-shaped branch away from the convex surface at a second flow rate, over the surface of the crescent branch away from the convex surface at a third flow rate, over the first channel at a fourth flow rate, and over the second channel at a fifth flow rate.
[0027] In some embodiments, both the second flow velocity and the third flow velocity are greater than the first flow velocity to create buoyancy that can support the frisbee body as it moves through the air.
[0028] In some embodiments, the fourth flow velocity is greater than the fifth flow velocity, so that the frisbee body rotates about the axis of the frisbee body while moving in the air, thus generating angular momentum.
[0029] In some embodiments, the frisbee is made of a soft material, in which case the frisbee is malleable so that it bounces back upon impact;
[0030] The frisbee can reduce the impact force acting on it through the rebound.
[0031] At least one beneficial effect of the frisbee provided by the embodiments of the present invention is that: the frisbee has a main body and three arc-shaped supports in the shape of swallow wings; the frisbee main body has an open groove inside, and this concave design can enhance the dynamic characteristics of the frisbee when it moves in the air, that is, improve the flight stability of the frisbee by reducing the air resistance to the bottom of the frisbee main body, so that the frisbee can be used in high wind environments; and the end of the frisbee main body away from the opening has a convex curved surface, and the above-mentioned three arc-shaped supports in the shape of swallow wings all protrude from the convex curved surface and are evenly distributed on the convex curved surface, forming a rotationally symmetrical structure with the center of the convex curved surface as the center of rotational symmetry, so that the weight of the frisbee can be evenly divided into three equal parts. Therefore, the above-mentioned three arc-shaped supports can not only support the top of the frisbee main body, but also form buoyancy to support the frisbee's movement in the air, so that the frisbee can fly smoothly and stably.

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0040] In this embodiment, the specific implementation of the "frisbee" is not limited, and those skilled in the art can selectively use any suitable implementation method according to actual needs.
[0041] Figure 1 This is a schematic diagram of the structure of a flying disc provided in an embodiment of the present invention. Figure 2 A top view of a frisbee provided in an embodiment of the present invention. Figure 3 A front view of a frisbee provided in an embodiment of the present invention.
[0042] Please see Figures 1-3 The frisbee 100 includes: a frisbee body 1 and three arc-shaped branches 2 in the shape of swallow wings.
[0043] The frisbee body 1 has a groove 102 with an opening 101 inside, and the end of the frisbee body 1 away from the opening 101 has a raised curved surface 103.
[0044] In addition, the opening 101 is located at the bottom of the frisbee body 1, and the raised curved surface 103 is located at the top of the frisbee body 1; and the airflow velocity over the raised curved surface 103 is greater than the airflow velocity over the bottom of the frisbee body 1.
[0045] In addition, the three arc-shaped branches 2, which are shaped like swallow wings, all protrude from the raised curved surface 103 and are evenly distributed on the raised curved surface 103.
[0046] Specifically, the three arc-shaped branches 2 form a rotationally symmetric structure, and the rotationally symmetric structure takes the center of the convex curved surface 103 as the rotational symmetry center.
[0047] In summary, the three arc-shaped supports 2 allow the weight of the frisbee 100 to be evenly divided into three parts. Therefore, the three arc-shaped supports 2 can not only support the top of the frisbee body 1, but also form buoyancy to support the frisbee 100 in the air, thus enabling the frisbee 100 to fly smoothly and stably.
[0048] It should be noted that one end of any arc-shaped branch 2 extends to the edge of the raised surface 103, and the other end extends in a direction close to the center of the raised surface 103.
[0049] In some embodiments, such as Figures 1-3 As shown, the opening 101 is located at the bottom of the main body of the frisbee 100, and the groove 102 has a preset groove depth.
[0050] Understandably, when the frisbee 100 is thrown, the groove 102 can reduce the drag between the air and the bottom of the frisbee 100 body; specifically, such a concave design can enhance the dynamic characteristics of the frisbee 100 when it moves in the air; in other words, such a concave design can improve the flight stability of the frisbee 100 by reducing the air resistance to the bottom of the frisbee body 1.
[0051] In some embodiments, combined with Figures 1-3 It can be seen that the frisbee 100 also includes: a circular branch 3 in a ring shape.
[0052] Among them, the circular branch 3 protrudes from the raised curved surface 103, and the circular branch 3 is coaxially arranged with the main body of the flying disc 100.
[0053] In addition, the end of any arc-shaped branch 2 away from the edge of the raised curved surface 103 is connected to the outer ring surface of the circular branch 3.
[0054] Furthermore, the circular support 3 has a small thickness in the axial direction of the frisbee body 1, so as not to affect the airflow; of course, the frisbee 100 may also be without the circular support 3 (that is, the thickness of the circular support 3 in the axial direction of the frisbee body 1 is zero).
[0055] In some embodiments, according to Figures 1-3 It can be seen that the frisbee 100 also includes: three 4-lobed branches.
[0056] It should be noted that all three dental limbs 4 protrude from the raised curved surface 103 and are evenly distributed on the raised curved surface 103; and the three dental limbs 4 can form the above-mentioned rotationally symmetrical structure.
[0057] In some embodiments, by Figures 1-3 It can be seen that the circular branch 3, the three arc-shaped branches 2 and the three crescent-shaped branches 4 are all integrally formed with the main body 1 of the flying disc.
[0058] In some embodiments, there is a preset region between two adjacent arcuate branches 2, and each crescent branch 4 is located within the preset region.
[0059] To further explain, each crescent branch 4 can divide a preset area to form a first flow channel 1001 and a second flow channel 1002, and the surface area of the first flow channel 1001 projected onto the raised surface 103 is smaller than the surface area of the second flow channel 1002 projected onto the raised surface 103.
[0060] In some embodiments, refer to Figures 1-3 It can be seen that when the frisbee 100 is thrown, the air flows over the bottom of the frisbee body 1 at the first flow speed, over the surface of the arc-shaped branch 2 away from the convex curved surface 103 at the second flow speed, over the surface of the crescent branch 4 away from the convex curved surface 103 at the third flow speed, over the first flow channel 1001 at the fourth flow speed, and over the second flow channel 1002 at the fifth flow speed.
[0061] In some embodiments, please continue reading Figures 1-3 The second and third flow velocities are both greater than the first flow velocity, so as to create buoyancy that can support the main body of the flying disc 100 as it moves in the air.
[0062] In some embodiments, please continue to refer to Figures 1-3 The fourth flow velocity is greater than the fifth flow velocity, so that the main body of the frisbee 1 moves in the air while rotating around the axis of the main body of the frisbee 100, thus generating an angular momentum.
[0063] Specifically, the aforementioned angular momentum allows the main body of the frisbee 1 to maintain smooth and stable flight when moving in the air (angular momentum conservation).
[0064] It should be noted that the conservation of angular momentum means that the angular momentum of a system remains constant when it is not acted upon by external forces or when the resultant torque of the external forces about a fixed point (or fixed axis) is always equal to zero. In particular, since the three arc-shaped branches 2 and the three crescent-shaped branches 4 mentioned above are all rotationally symmetric structures, with the center of the convex curved surface 103 as the center of rotational symmetry, and this center of rotational symmetry is located on the axis of the main body of the flying disc 1, the resultant torque of the three arc-shaped branches 2 and the three crescent-shaped branches 4 about the axis of the main body of the flying disc 1 is always equal to zero, thus conforming to the conservation of angular momentum. Therefore, when the main body of the flying disc 1 moves in the air and rotates around the axis of the main body of the flying disc 100, the main body of the flying disc 1 can always maintain the stability of the axis of rotation when moving in the air, thereby enabling the flying disc 100 to fly smoothly and stably.
[0065] In some embodiments, such as Figures 1-3 As shown, the frisbee 100 is made of a soft material (e.g., soft plastic), which gives the frisbee 100 flexibility so that it bounces back upon impact. Soft plastic refers to plastic materials that are soft and have good deformability. In addition, soft plastic is easier to process and mold, and it usually has excellent properties such as shock absorption, slip resistance, and strong protection.
[0066] In addition, the frisbee 100 can form a buffer through rebound, thereby reducing the impact force acting on the frisbee 100.
[0067] In this embodiment, the three arc-shaped supports 2, which are rotationally symmetrical and have rotational inertia, combined with the ductility of the soft material, enable the three arc-shaped supports 2 to have the functions of support and rebound, thereby providing support for the main body of the frisbee 1 and thus preventing the frisbee 100 from being damaged by impact or external force.
[0068] Combination Figures 1-3 It is understood that by incorporating three arc-shaped branches 2 resembling swallow wings, the frisbee 100 can improve its flight stability, making it easier for users to throw and catch. In addition, since the frisbee 100 is made of soft materials, its safety can be improved. This design gives the frisbee 100 advantages such as safety and reliability, ease of throwing and catching, no harm to users, no noise, and suitability for a wide range of people, thereby popularizing frisbee games among various age groups and specific populations (e.g., children, the elderly, and those undergoing rehabilitation therapy).
[0069] In summary, the frisbee provided in this embodiment of the invention has a main body and three swallow-wing-shaped arc-shaped supports. The main body has an open groove inside, which enhances the frisbee's dynamic characteristics during air movement. This is achieved by reducing air resistance at the bottom of the main body, thus improving flight stability and enabling its use in high-wind environments. Furthermore, the end of the main body away from the opening has a convex curved surface, and the three swallow-wing-shaped arc-shaped supports protrude from this surface and are evenly distributed, forming a rotationally symmetrical structure with the center of the convex surface as the center of rotational symmetry. This allows the weight of the frisbee to be evenly divided into three parts. Therefore, the three arc-shaped supports not only support the top of the main body but also provide buoyancy to support the frisbee's movement in the air, enabling smooth and stable flight. Thus, the frisbee provided in this embodiment of the invention has a certain novelty compared to traditional frisbees.
[0070] The above description, in conjunction with specific / preferred embodiments, provides a further detailed explanation of the present invention, but it should not be construed as limiting the specific implementation of the invention to these descriptions. Those skilled in the art will recognize that various modifications and improvements can be made without departing from the concept of the present invention, and all such modifications and improvements fall within the scope of protection of the present invention.
