Technical Field
[0001] This utility model relates to the field of water sports technology, specifically to a propulsion fin. Background Technology
[0002] Traditional fin designs often focus on basic propulsion, but they fall short in terms of structural strength, water flow efficiency, and user comfort. For example, the connection between the fin and the paddle is prone to wear, affecting its lifespan; at the same time, the lack of effective flow guidance design leads to low propulsion efficiency; furthermore, users' feet may feel uncomfortable due to restriction during prolonged use. Therefore, it is necessary to improve existing fins to address these issues. 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 booster shin fin.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a propulsive shin booster, comprising:
[0005] The shoe body and the paddle;
[0006] The bottom of the shoe body is connected to the paddle body, and the front of the shoe body is provided with an opening through which the user's foot extends;
[0007] Both sides of the opening are provided with first reinforcing ribs, which extend from both sides of the opening to the end of the propeller body and extend to the bottom surface of the propeller body.
[0008] Main working principle: This propulsion fin consists of a shoe body and a propeller. The shoe body, as the main support for the user's foot, is ergonomically designed to ensure comfort and provide sufficient stability. The propeller, connected to the bottom of the shoe body, is the key component for generating propulsion. An opening at the front of the shoe body allows the user's foot to extend, increasing flexibility during swimming or diving, allowing for better control of the fin's movements, and reducing the feeling of restriction on the feet. The first reinforcing ribs on both sides of the opening not only enhance the structural strength between the shoe body and the propeller but also guide water flow. These reinforcing ribs extend from both sides of the opening to the end of the propeller and continue to the bottom of the propeller, forming a continuous water flow channel.
[0009] When a user swims or dives in the water, the fins are propelled by the swinging of the feet and kicking of the legs. The open feet allow for more direct control of the paddle's movement. During the kicking motion, the paddle moves through the water, generating backward thrust. Due to the shape of the paddle and the guidance of the first reinforcing rib, the water flow is effectively guided and accelerated across the paddle, thus increasing propulsion. The presence of the first reinforcing rib not only enhances structural stability but also improves propulsion efficiency by optimizing the water flow path. They ensure that the water flow is fully utilized on the bottom surface of the paddle, reducing turbulence and energy loss.
[0010] This design combines ergonomic and hydrodynamic principles to improve comfort and propulsion efficiency while swimming or diving. By allowing the foot to extend and enhancing structural strength, the booster fin provides users with better control and stability.
[0011] In summary, the working principle of this propulsion fin mainly relies on its unique opening design and first reinforcing rib structure, which work together to improve propulsion and user experience during swimming or diving.
[0012] Preferably, the end of the first reinforcing rib is provided with a guide fin, and the bottom surface and the surface of the first reinforcing rib are both provided with the guide fin, which is perpendicular to the surface of the propeller.
[0013] Preferably, a first guide groove is provided between the first reinforcing ribs on both sides, and the first guide groove faces the end of the propeller body.
[0014] Preferably, the bottom of the paddle body is provided with a second reinforcing rib, and the two ends of the second reinforcing rib are respectively connected to the bottom of the shoe body and the first guide groove.
[0015] Preferably, a third reinforcing rib is provided on both sides of the paddle body, and the third reinforcing rib extends from the connection between the paddle body and the shoe body to the end of the paddle body.
[0016] Preferably, a flow guide hole is provided between the first reinforcing rib and the third reinforcing rib on the same side, the flow guide hole extending from the surface of the propeller to the bottom surface of the propeller, and the flow guide hole facing the end of the propeller.
[0017] Preferably, the bottom of the inner cavity of the shoe body is provided with striped patterns, and the striped patterns are aligned with the opening.
[0018] Preferably, the shoe body is provided with a granular texture, and the granular texture is aligned with the orientation of the opening.
[0019] Preferably, the shoe body 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 end of the propeller body is provided with a hanging hole.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] This invention features an opening at the front of the shoe body that allows the user's foot to extend naturally, reducing the feeling of restriction and increasing foot flexibility. This allows users to control their movements more freely when swimming or diving, improving overall comfort. A first reinforcing rib extends from both sides of the opening to the end of the paddle and continues to the bottom of the paddle. This design not only enhances the structural strength between the shoe and the paddle but also facilitates manufacturing and improves propulsion efficiency by optimizing the water flow path. The presence of the reinforcing rib guides water flow more smoothly across the paddle, reducing water resistance and thus increasing backward thrust. The introduction of the first reinforcing rib significantly enhances the connection strength between the shoe and the paddle, making the entire fin structure more stable, able to withstand greater force, and extending its service life. Simultaneously, the reinforcing rib also provides support, allowing the user to maintain better stability when kicking the fin.
[0023] In conclusion, this propulsion shin design has brought significant benefits in terms of improving user experience, increasing propulsion efficiency, enhancing durability and stability, improving adaptability, and balancing innovation with practicality. 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 propulsion shin glide, such as Figures 1-3 As shown, the fins consist of the shoe body and the paddle. The shoe body, as the primary support for the user's foot, must be ergonomically designed to ensure comfort and provide sufficient stability. The paddle, connected to the bottom of the shoe body, is a key component for generating propulsion. An opening at the front of the shoe body allows the user's foot to extend, increasing flexibility during swimming or diving, allowing for better control of the fin's movements, and reducing the feeling of restriction on the feet. The first reinforcing ribs on both sides of the opening not only enhance the structural strength between the shoe body and the paddle but also guide water flow. These reinforcing ribs extend from both sides of the opening to the end of the paddle and continue to the bottom of the paddle, forming a continuous water flow channel.
[0033] When a user swims or dives in the water, the fins are propelled by the swinging of the feet and kicking of the legs. The open feet allow for more direct control of the paddle's movement. During the kicking motion, the paddle moves through the water, generating backward thrust. Due to the shape of the paddle and the guidance of the first reinforcing rib, the water flow is effectively guided and accelerated across the paddle, thus increasing propulsion. The presence of the first reinforcing rib not only enhances structural stability but also improves propulsion efficiency by optimizing the water flow path. They ensure that the water flow is fully utilized on the bottom surface of the paddle, reducing turbulence and energy loss.
[0034] This design combines ergonomic and hydrodynamic principles to improve comfort and propulsion efficiency while swimming or diving. By allowing the foot to extend and enhancing structural strength, the booster fin provides users with better control and stability.
[0035] In summary, the working principle of this propulsion fin mainly relies on its unique opening design and first reinforcing rib structure, which work together to improve propulsion and user experience during swimming or diving.
[0036] In some optional embodiments, guide fins are provided at the ends of the first reinforcing rib, covering the bottom and surface of the reinforcing rib and remaining perpendicular to the propeller surface. The design of the guide fins helps guide water flow, further reducing water resistance. When the user kicks the fins, the guide fins guide the water flow more smoothly across the propeller, reducing turbulence and energy loss, thereby improving propulsion efficiency. At the same time, the design of the guide fins enhances the overall aesthetics of the propeller.
[0037] In some optional embodiments, a first guide channel is provided between the first reinforcing ribs on both sides, facing the end of the paddle body. The design of the guide channel helps to further optimize the water flow path. When the user kicks the fin, the water flow is guided into the first guide channel, reducing the residence time of the water on the paddle body surface, thereby reducing drag. This further optimizes the water flow path and reduces drag, improving propulsion efficiency and making it easier for the user to swim or dive.
[0038] In some optional embodiments, the booster fins are further reinforced with second reinforcing ribs at the bottom of the paddle body. These second reinforcing ribs are connected at both ends to the bottom of the fin and the first flow channel, respectively, forming a more stable support structure. The introduction of the second reinforcing ribs not only enhances the connection strength between the fin and the paddle body but also further improves propulsion efficiency by optimizing the water flow path.
[0039] When a user swims in the water wearing these propulsion fins, the second reinforcing rib works in conjunction with the first reinforcing rib and the first guide channel to guide water flow more smoothly across the paddle body. The presence of the second reinforcing rib reduces the residence time of water at the bottom of the paddle body, lowering water resistance and thus improving propulsion efficiency. Simultaneously, the second reinforcing rib also enhances the structural strength of the paddle body, making the fins more durable over extended use. It not only strengthens the connection between the fin and the paddle body, improving the overall structural stability, but also optimizes the water flow path, further reducing water resistance, increasing propulsion efficiency, and enhancing the durability and lifespan of the fins.
[0040] In some alternative embodiments, third reinforcing ribs are provided on both sides of the paddle body, extending from the connection between the paddle body and the shoe body to the end of the paddle body. The design of the third reinforcing ribs provides additional support to the paddle body, enhancing the overall structural stability. When the user kicks the fins, the third reinforcing ribs can disperse the force generated by the kick, reducing paddle body deformation and wear, enhancing the structural strength of the paddle body, and extending its service life.
[0041] In some alternative embodiments, the propulsion fin has flow guide holes between the first and third reinforcing ribs on the same side. These flow guide holes extend from the surface of the propeller to the bottom surface of the propeller and face towards the end of the propeller. The flow guide holes are designed to further optimize the water flow path, reduce water stagnation and turbulence on the propeller surface, thereby improving propulsion efficiency.
[0042] When the user kicks the fins, the water is guided into the guide holes and flows smoothly over the paddle. The presence of the guide holes reduces water collision and stagnation on the paddle surface, lowering water resistance. Simultaneously, the guide holes promote water flow within the paddle body, enhancing propulsion. This design allows users to swim or dive with less effort and increase swimming speed. Further optimizing the water flow path, reducing stagnation and turbulence on the paddle surface, and improving propulsion efficiency, the guide hole design enhances the paddle's propulsive effect, making swimming or diving more effortless.
[0043] In some alternative embodiments, stripes are formed on the bottom of the shoe's inner cavity, with these stripes aligned with the opening direction. The stripe design helps increase friction between the foot and the shoe body, improving stability. When the user wears the fins, the sole of the foot is in close contact with the stripes, reducing the likelihood of slipping and slipping off, thus improving stability and increasing user comfort and confidence.
[0044] In some alternative embodiments, retaining brackets are provided on both sides of the shoe body, which cooperate with the ends of the shoelaces. The retaining brackets are designed to allow the user to easily adjust the tightness of the shoelaces, ensuring a stable and comfortable fit. By adjusting the tightness of the shoelaces, the user ensures that the shoe body fits snugly against the foot, reducing the risk of slipping and improving stability and comfort.
[0045] In some optional embodiments, hanging holes are provided at the end of the paddle body, which facilitates the user's carrying and storage of the fins. Users can hang the fins in a suitable position using a lanyard or other suspension device for easy carrying and storage. This improves the portability and storage convenience of the fins, reducing the trouble and inconvenience for users when carrying and storing them.
[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
