Description

Technical Field

[0001] This utility model relates to the field of water sports equipment technology, specifically to a type of fin. Background Technology

[0002] Traditional fin devices mainly consist of a shoe and a paddle, designed to enhance the user's leg strength and increase propulsion speed in the water. However, existing fin devices have shortcomings in paddle design, water flow guidance, and overall structure, affecting the user's swimming efficiency and comfort. Therefore, it is necessary to improve the fin device to enhance its propulsion efficiency and user experience. Utility Model Content

[0003] In order to overcome the problems existing in the prior art, the purpose of this utility model is to provide a fin.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a fin, comprising:

[0005] The shoe body and the paddle;

[0006] The shoe body includes an upper, a toe box, and a sole, which together form a shoe cavity that can accommodate the foot.

[0007] One end of the paddle is connected to the shoe upper, the other end of the paddle extends outward, and the other end of the paddle bends at a certain angle toward the sole of the shoe. The connection between the paddle and the toe of the shoe forms a paddling cavity.

[0008] The paddling cavity is equipped with a repositioning reinforcing rib, which connects the shoe toe and the paddle body.

[0009] Main working principle: This fin consists of a shoe body and an oar. The shoe body is designed to wrap around and protect the user's foot. The shoe body comprises the upper, the toe box, and the sole, forming a comfortable cavity that ensures the user's foot is securely placed within it. The oar is the key component of the fin; one end connects to the upper, while the other end extends outward and bends at an angle towards the sole. This design mimics the webbed feet of a frog, generating greater thrust in the water. The stroke chamber is the space formed by the connection between the oar and the toe box; it's the area where the fin generates additional thrust during strokes. A reinforcing rib located within the stroke chamber firmly connects the toe box and oar, enhancing structural stability and facilitating the oar's rapid return to its original position after each stroke, ready for the next stroke.

[0010] When users use fins to paddle, their feet remain stable within the fin cavity. As the legs push backward, the curved part of the paddle first contacts the water surface and begins the backward stroke. Due to the paddle's special design, it can more effectively capture water flow and generate greater thrust during the backward stroke. This thrust comes not only from the paddle's linear motion but also from the efficient use of water flow by its curved part. The return ribs within the stroke cavity ensure structural stability and also guide the paddle back to its starting position. As the paddle completes a stroke and begins to swing forward, the return ribs help the paddle quickly return to its starting position, preparing for the next stroke. Through continuous, powerful strokes, fins provide users with sustained forward momentum, enabling them to swim more efficiently in the water.

[0011] In summary, the design of this fin fully utilizes the curved shape of the paddle body and the reinforcing ribs within the stroke chamber to enhance propulsion efficiency in the water and ensure that users can use it comfortably and stably for swimming.

[0012] Preferably, reset bars are provided on both sides of the propeller body, the reset bars are perpendicular to the propeller body, and the reset bars extend to the upper and lower surfaces of the propeller body.

[0013] Preferably, the propeller body is provided with multiple guide grooves, which extend to the ends of the propeller body.

[0014] Preferably, the guide channel includes a first guide channel, and two first guide channels are provided. The two first guide channels are provided on the upper surface of the propeller body, and the two first guide channels are respectively provided on both sides of the centerline of the propeller body.

[0015] Preferably, the guide channel further includes a second guide channel, which is disposed between the two first guide channels and on the upper surface of the propeller body.

[0016] Preferably, the guide channel further includes a third guide channel, of which two third guide channels are provided, which are respectively provided on both sides of the second guide channel and are provided on the lower surface of the propeller.

[0017] Preferably, a guide fin is provided between the first guide groove and the third guide groove. The guide fin is symmetrically arranged on the upper surface and the lower surface of the paddle body with the paddle body as the symmetrical face, and the guide fin gradually narrows towards the end of the shoe body.

[0018] Preferably, the sole is provided with a wavy pattern, which is perpendicular to the direction of the toe.

[0019] Preferably, the shoe toe is provided with fixing seats on both sides, and the fixing seats on both sides cooperate with the two ends of the shoelace.

[0020] Preferably, the surface of the shoe cavity is provided with multiple drainage outlets.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This invention features a paddle that extends outward and bends at an angle towards the sole, a design that more effectively catches water and generates greater thrust during the backward stroke. This helps users increase swimming speed and reduce energy consumption in breaststroke or similar strokes. The shoe design ensures the user's foot is securely placed within it, preventing slippage or discomfort during swimming. Simultaneously, the reinforcing ribs within the stroke chamber not only enhance structural stability but also help maintain the paddle's correct position during the stroke, further improving swimming stability and control. The reinforcing ribs also help the paddle quickly return to its original position after the stroke, preparing for the next stroke. This helps users maintain continuous, powerful strokes, improving swimming fluidity and efficiency.

[0023] In summary, this frog-foot design, by mimicking the shape of a frog's webbed feet and optimizing structural details, improves swimming efficiency, enhances stability, increases comfort, facilitates easy repositioning and continuous strokes, and boasts excellent durability and reliability. These benefits make the frog-foot design an ideal choice for users to improve their swimming skills and enjoy swimming. Attached Figure Description

[0029] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0031] Example 1

[0032] This embodiment discloses a fin device, such as... Figures 1-3 As shown, the shoe body 1 is designed to wrap around and protect the user's foot. The shoe body 1 consists of the upper 10, the toe box 11, and the sole 12, which together form a comfortable shoe cavity 4, ensuring the user's foot is securely placed within it. The paddle 2 is a key part of the fin; one end connects to the upper 10, while the other end extends outward and bends at an angle towards the sole 12. This design mimics the webbed feet of a frog, generating greater thrust in the water. The paddling cavity 3 is the space formed by the connection between the paddle 2 and the toe box 11; it is the area where the fin generates additional thrust during paddling. A reinforcing rib 26, located within the paddling cavity 3, firmly connects the toe box 11 and the paddle 2, enhancing structural stability and facilitating the rapid return of the paddle 2 to its original position after the paddling motion, ready for the next stroke.

[0033] When users use fins to paddle, their feet remain stable within the fin cavity 4. As the legs push backward, the curved portion of the paddle 2 contacts the water surface first and begins to paddle backward. Due to the special design of the paddle 2, it can more effectively capture the water flow and generate greater thrust during the backward paddle. This thrust comes not only from the linear motion of the paddle 2 but also from the effective use of the water flow by its curved portion. The return reinforcement rib 26 within the paddle cavity 3 ensures structural stability and also guides the paddle 2 to return to its starting position. When the paddle 2 completes a stroke and begins to swing forward, the return reinforcement rib 26 helps the paddle 2 quickly return to its starting position, preparing for the next stroke. Through continuous and powerful strokes, the fins provide users with sustained forward momentum, enabling them to swim more efficiently in the water.

[0034] In summary, the design of this fin fully utilizes the curved shape of the paddle body 2 and the restoring reinforcing rib 26 within the phasing chamber 3 to enhance propulsion efficiency in water and ensure that users can use it comfortably and stably for swimming.

[0035] In some optional embodiments, reset baffles 20 are provided on both sides of the paddle body 2. The reset baffles 20 are perpendicular to the paddle body 2 and extend towards the upper and lower surfaces of the paddle body 2. The reset baffles 20 further improve the reset speed of the paddle body 2. At the same time, the space enclosed by the reset baffles 20 and the paddle body 2 can better grasp the water flow, ensuring that the paddle body 2 remains stable during the stroke and enhancing the stroke effect. This improves stroke stability, reduces paddle body sway, and further enhances swimming efficiency.

[0036] In some optional embodiments, multiple guide channels are provided on the paddle body 2, extending to the end of the paddle body 2. The guide channels guide the water flow, reduce water flow resistance, improve the paddling efficiency of the paddle body 2, optimize the water flow path, reduce energy consumption, and increase swimming speed.

[0037] In some optional embodiments, two first guide grooves 21 are provided on the upper surface of the paddle body 2, respectively located on both sides of the centerline of the paddle body 2. The first guide grooves 21 guide the water flow, allowing the water to flow more smoothly through the paddle body 2, improving the paddling effect, enhancing the water flow utilization rate on the upper surface of the paddle body 2, and improving swimming efficiency.

[0038] In some optional embodiments, first guide channels 21 are provided on both sides of the second guide channel 23, and the second guide channel 23 is located on the upper surface of the paddle body 2. The second guide channel 23 further optimizes the water flow path and works together with the first guide channel 21 to improve the paddling efficiency, enhance the water flow guidance effect, and increase the swimming speed.

[0039] In some optional embodiments, two third guide channels 24 are provided on the lower surface of the paddle body 2, respectively located on both sides of the second guide channel 23. The third guide channels 24, together with the first and second guide channels 23, form a complete water flow guiding system, improving paddling efficiency. Optimizing the water flow path on the upper and lower surfaces of the paddle body 2 enhances swimming efficiency.

[0040] In some optional embodiments, a guide fin 25 is provided between the first guide channel 21 and the third guide channel 24. The guide fin 25 is symmetrically arranged with respect to the paddle body 2. The guide fin 25 further guides the water flow, reduces water flow turbulence, improves the paddling effect, enhances water flow stability, and improves swimming efficiency.

[0041] In some optional embodiments, a wavy pattern 13 is provided on the sole 12, with the pattern perpendicular to the toe 11. The wavy pattern 13 increases the friction between the sole 12 and the ground, improves grip, prevents slipping, enhances the stability of the sole 12, and improves the user's safety.

[0042] In some optional embodiments, fixing seats 14 are provided on both sides of the toe 11. The fixing seats 14 cooperate with the two ends of the shoelaces. The fixing seats 14 and the shoelaces work together to ensure that the fins are firmly fixed on the user's feet, improve the stability of the fins, prevent them from falling off during swimming, and ensure swimming safety.

[0043] In some optional embodiments, multiple drainage holes 15 are provided on the surface of the shoe cavity 4. The drainage holes 15 promptly drain water accumulated inside the shoe cavity 4, keeping the inside of the shoe dry and comfortable, improving the comfort of the fins, reducing discomfort caused by water accumulation, and enhancing the swimming experience.

[0044] In summary, this fin design achieves beneficial effects such as improving swimming efficiency, enhancing stability, increasing comfort, and improving safety through improvements in various aspects, including optimizing the structure of the paddle body 2, setting up flow channels and flow fins 25, enhancing the stability of the sole 12, and improving the comfort of the shoe cavity 4.
