Description

Technical Field

[0001] This utility model relates to the field of swimming equipment technology, specifically to a swimming and diving fin. Background Technology

[0002] In swimming and diving, fins serve as an auxiliary tool, playing a crucial role in improving swimmers' speed and efficiency. Traditional and current fin designs vary widely, but they generally consist of a shoe body and fins. Improvements have primarily focused on shoe comfort and aesthetic innovation, while breakthroughs remain in optimizing the dynamic performance of the fins.

[0003] Traditional fin designs often employ relatively simple structures, such as a combination of fixed-shaped fin plates and fin ribs. While this design is stable and reliable, its propulsive efficiency and flexibility are insufficient when facing complex and changing water currents. Specifically, when fins move in the water, traditional fin designs cannot automatically adjust their contact area with the water surface according to dynamic changes in water flow, thus limiting the maximization of propulsion. Furthermore, using traditional fins requires significant physical exertion from kicking the legs, resulting in a poor user experience. Utility Model Content

[0004] The purpose of this invention is to provide a swimming and diving fin to solve the technical problems mentioned in the background art, such as insufficient propulsion and high physical exertion of users in traditional fins.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A swimming and diving fin includes a fin body and a web body. The web body includes two connecting fin ribs, a web plate integrally connected between the two connecting fin ribs, and side wings disposed on both sides of the web plate in the width direction. When the fin is in water, the side wings undergo angular deformation to change the size of the contact surface between the web body and the water.

[0007] Furthermore, a groove is formed at the connection between the side wing and the webbed plate. The groove extends forward in a figure-eight shape along the length of the webbed body, and the side wing can move up and down around the groove to produce angular deformation.

[0008] Furthermore, the groove includes an upper groove and a lower groove that are recessed on the upper and lower surfaces of the connection.

[0009] Furthermore, when stationary, viewed from the main viewing direction, the side wings and the webbed plate form an obtuse angle structure.

[0010] Furthermore, the fin body and the webbed body are integrally molded structures.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention utilizes the dynamic angular deformation of the side wings, allowing the fins to more effectively convert the force of the water kick into forward propulsion, thereby significantly improving speed during swimming and diving. The optimized water flow design reduces frictional resistance between the fins and water during the kick, improving overall energy efficiency. It also helps to disperse the impact force during the kick, reducing the burden on the wearer's feet and enhancing comfort during swimming and diving. Attached Figure Description

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0023] like Figure 1-4 As shown, a swimming / diving fin includes a fin body 1 and a webbed body 2. The webbed body 2 includes two connecting fin ribs 3, a webbed plate 4 integrally connected between the two connecting fin ribs 3, and side wings 5 ​​disposed on both sides of the webbed plate 4 in the width direction. When swimming, the side wings 5 ​​undergo angular deformation to change the contact area between the webbed body 2 and the water. A groove 6 is formed at the connection between the side wings 5 ​​and the webbed plate 4. The groove 6 extends forward in a figure-eight shape along the length direction of the webbed body 2, and the side wings 5 ​​can move up and down around the groove 6 to generate angular deformation. The groove 6 includes an upper groove 61 and a lower groove 62 recessed on the upper and lower surfaces of the connection.

[0024] Angular deformation mechanism: When the wearer pushes off the water, the force of the foot is transmitted to the fin body 2 through the fin body 1. At this time, the side wings 5 ​​are subjected to water resistance and move up and down around the groove 6, forming an angular deformation. This deformation allows the fin body 2 to dynamically adjust its contact area with the water during the push-off process, thereby optimizing the streamline of the water flow through the fin body 2, reducing resistance and increasing propulsion.

[0025] Specifically, the application process of this utility model is as follows:

[0026] When the wearer's feet paddle downwards, the two side wings 5 ​​can unfold to the sides of the fin plate 4 to increase the contact area with the water, thereby increasing propulsion and speed. When the wearer's feet paddle upwards, the two side wings 5 ​​can retract back to the center of the fin plate 4 to reduce the contact area with the water, thereby reducing water resistance, saving the wearer's energy, and increasing the frequency and amplitude of the fin strokes.

[0027] Specifically, as shown in the figure, when stationary and viewed from the main viewpoint, the side wing 5 and the webbed plate 4 form an obtuse angle. This helps to provide a larger contact area in the initial stage of the kick, increasing stability during the kick. As the kicking motion progresses, the side wing 5 gradually unfolds, further increasing propulsion.

[0028] Specifically, as shown in the figure, the fin body 1 and the webbed body 2 are integrally formed structures.

[0029] It is worth mentioning that the fin body 1 and the webbed body 2 can also be detachable and installable. As long as the webbed body 2 adopts the same principle and structure, it is within the protection scope of this utility model.

[0030] This invention, through the dynamic angular deformation of the side wings 5, allows the fins to more effectively utilize the force of the water kick, converting it into forward propulsion, thereby significantly improving speed during swimming and diving. The optimized water flow design reduces frictional resistance between the fins 2 and the water during the kick, improving overall energy efficiency. It also helps to disperse the impact force during the kick, reducing the burden on the wearer's feet and enhancing comfort during swimming and diving.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
