FLYING DISC

Description

TECHNICAL FIELD

The invention related to the field of sports equipment technology, particularly related to a flying disc with simplicity and stability.

BACKGROUND

Flying disc games (also called frisbee sports) are simple yet challenging outdoor activities suitable for teams or individuals. However, despite having many advantages, flying disc games also have several drawbacks:

• • (1) While flying disc games appear simple, they require users to accurately control the disc's flight trajectory, speed, and angle, making them technically demanding. Generally, beginners may encounter issues such as discs veering off target, landing too far away, or lacking precise delivery;
  • (2) Although flying disc games don't require complex equipment, they do have specific venue requirements. Specifically, these games typically need an open space for throwing and catching the disc;
  • (3) In flying disc games, air (or wind) is a decisive factor in determining whether the disc can maintain stable flight (for example, strong winds or unstable wind speeds can lead to unstable disc flight). If the disc's flight is unstable, it will affect the user's experience of the game;
  • (4) Traditional flying discs available in the market are often made of hard plastic or fabric materials, which may develop cracks or deform after strong impacts or prolonged use, affecting their flight performance. In particular, discs made of hard materials are more susceptible to damage from external forces.

In the current market, users refer to rotatable discs as flying discs; generally, common flying discs are manufactured as one-piece molded structures.

In summary, traditional flying discs in existing technology still have deficiencies such as insufficient flight stability and susceptibility to damage upon impact.

SUMMARY

The flying disc disclosed by the invention address at least some of the deficiencies of existing flying discs.

The invention provides a flying disc. The flying disc includes: a disc body; wherein the disc body has an internal cavity with an opening, and a raised curved surface is provided on an end of the disc body away from the opening; three swallow wing-shaped curved ribs protruding from the raised curved surface and evenly distributed on the raised curved surface; wherein the three curved ribs are arranged in rotational symmetry about the center of the raised curved surface; wherein one end of each curved rib extends to the edge of the raised curved surface, and the other end extends toward the center of the raised curved surface.

In some embodiments, the opening is located at the bottom of the disc body, and the cavity has a preset depth; when the flying disc is thrown, the cavity reduces air resistance between the air and the bottom of the disc body.

In some embodiments, the flying disc also includes: a ring-shaped circular rib protruded from the raised curved surface and coaxially arranged with the disc body; wherein the end of each curved rib away from the edge of the raised curved surface connects with an outer surface of the circular rib.

In some embodiments, the flying disc also includes: three crescent-shaped ribs protruding from the raised curved surface and evenly distributed on the raised curved surface; wherein the three crescent-shaped ribs are arranged in rotational symmetry.

In some embodiments, the circular rib, three curved ribs, and three crescent-shaped ribs are formed as a unitary structure with the disc body.

In some embodiments, a preset area is defined between each pair of adjacent curved ribs, and each crescent-shaped rib is located within the corresponding preset area; each crescent-shaped rib divides the corresponding preset area into a first channel and a second channel, wherein the first flow channel has a smaller projected area than the second flow channel when projected onto the raised curved surface.

In some embodiments, when the flying disc is thrown, air flows at a first velocity past the bottom of the disc body, at a second velocity past the surface of the curved ribs away from the raised curved surface, at a third velocity past the surface of the crescent-shaped ribs away from the raised curved surface, at a fourth velocity through the first channel, and at a fifth velocity through the second channel.

In some embodiments, both the second velocity and the third velocity are greater than the first velocity, creating lift that supports the disc body's movement through the air.

In some embodiments, the fourth velocity is greater than the fifth velocity, causing the disc body to rotate around its axis while moving through the air, thereby creating angular momentum.

In some embodiments, the flying disc is made of a flexible material providing extensibility, such that the flying disc rebounds upon impact; wherein the rebound reduces impact forces acting on the flying disc.

At least one advantages of the flying disc according to the embodiment of the invention is: the flying disc has a disc body and three swallow wing-shaped curved ribs; the disc body has an internal cavity with an opening, and this concave design can enhance the aerodynamic characteristics of the disc during flight, specifically by reducing air resistance at the bottom of the disc body to improve flight stability, thereby enabling the disc to be used in high-wind conditions; furthermore, the end of the disc body away from the opening has a raised curved surface, and the three swallow wing-shaped curved ribs protrude from this surface and are evenly distributed on it, forming a rotationally symmetric structure with the center of the raised curved surface as the center of rotational symmetry, which allows the disc's weight to be evenly divided into three parts, therefore these three curved ribs not only support the top of the disc body but also create lift for the disc's movement through the air, enabling smooth and stable flight.

FIG. 1 is a structural schematic diagram of the flying disc according to the embodiment of the invention. FIG. 2 is a top view of the flying disc according to the embodiment of the invention. FIG. 3 is a front view of the flying disc according to the embodiment of the invention.

Referring to FIGS. 1-3, the flying disc 100 includes: a disc body 1 and three swallow wing-shaped curved ribs 2.

The disc body 1 has an internal cavity 102 with an opening 101, and the end of the disc body 1 away from the opening 101 has a raised curved surface 103.

Additionally, the opening 101 is located at the bottom of the disc body 1, and the raised curved surface 103 is at the top of the disc body 1; furthermore, the air velocity flowing over the raised curved surface 103 is greater than the air velocity flowing past the bottom of the disc body 1.

Moreover, the three swallow wing-shaped curved ribs 2 all protrude from the raised curved surface 103 and are evenly distributed on it.

Specifically, the three curved ribs 2 form a rotationally symmetric structure, with the center of the raised curved surface 103 serving as the center of rotational symmetry.

In summary, the three curved ribs 2 allow the weight of this flying disc 100 to be evenly divided into three parts, therefore these three curved ribs 2 not only support the top of the disc body 1 but also create lift for the disc's movement through the air, enabling smooth and stable flight.

It should be noted that one end of each curved rib 2 extends to the edge of the raised curved surface 103, and the other end extends toward the center of the raised curved surface 103.

In some embodiments, as shown in FIGS. 1-3, the opening 101 is located at the bottom of the disc body 100, and the cavity 102 has a preset depth.

It can be understood that when the flying disc 100 is thrown, the cavity 102 can reduce air resistance between the air and the bottom of the disc body 100; specifically, this concave design can enhance the aerodynamic characteristics of the disc during flight; in other words, this concave design can improve the flight stability of the disc 100 by reducing air resistance at the bottom of the disc body 1.

In some embodiments, as shown in FIGS. 1-3, the flying disc 100 also includes: a ring-shaped circular rib 3.

The circular rib 3 protrudes from the raised curved surface 103 and is coaxially arranged with the disc body 100.

Additionally, the end of each curved rib 2 away from the edge of the raised curved surface 103 connects to the outer surface of the circular rib 3.

Furthermore, the circular rib 3 has a small thickness in the axial direction of the disc body 1, thus not affecting air flow; of course, the flying disc 100 can also be without the circular rib 3 (i.e., the thickness of the circular rib 3 in the axial direction of the disc body 1 is zero).

In some embodiments, as shown in FIGS. 1-3, the flying disc 100 also includes: three crescent-shaped ribs 4.

It should be noted that the three crescent-shaped ribs 4 all protrude from the raised curved surface 103 and are evenly distributed on it; furthermore, the three crescent-shaped ribs 4 can form the aforementioned rotationally symmetric structure.

In some embodiments, as shown in FIGS. 1-3, the circular rib 3, three curved ribs 2, and three crescent-shaped ribs 4 are all integrally formed with the disc body 1.

In some embodiments, there is a preset area between adjacent curved ribs 2, and each crescent-shaped rib 4 is located within the preset area.

To further explain, each crescent-shaped rib 4 divides the preset area into a first channel 1001 and a second channel 1002, and the projected area of the first channel 1001 on the raised curved surface 103 is smaller than that of the second channel 1002.

In this embodiment of the application, the three rotationally symmetric curved ribs 2 with rotational inertia, combined with the extensibility of the soft material, enable all three curved ribs 2 to have support and rebound functions, thereby providing support for the disc body 1 and preventing damage to the flying disc 100 from impact or external forces.

As shown in FIGS. 1-3, this flying disc 100, through the addition of three swallow wing-shaped curved ribs 2, can improve its flight stability, making it easier for users to throw and catch; furthermore, since this flying disc 100 is made of soft material, it enhances safety; this design gives the flying disc 100 advantages such as being safe and reliable, easy to throw and catch, causing no harm to users, producing no noise, and being suitable for the general public, thus making flying disc games accessible to users of various age groups and specific populations (such as children, elderly people, and rehabilitation patients).

In summary, the flying disc according to the embodiment of the invention has a disc body and three swallow wing-shaped curved ribs; the disc body has an internal cavity with an opening, and this concave design enhances the disc's aerodynamic characteristics during flight, specifically by reducing air resistance at the bottom of the disc body to improve flight stability, enabling the disc to be used in high-wind conditions; furthermore, the end of the disc body away from the opening has a raised curved surface, and the three swallow wing-shaped curved ribs protrude from this surface, are evenly distributed on it, and form a rotationally symmetric structure with the center of the raised curved surface as the center of rotational symmetry, allowing the disc's weight to be evenly divided into three parts, therefore these three curved ribs not only support the top of the disc body but also create lift for the disc's movement through the air, enabling smooth and stable flight. Therefore, the flying disc provided in this embodiment of the invention has certain novelty compared to traditional flying discs.
