Description

Technical Field

[0001] The present invention belongs to the field of sports equipment, and particularly relates to a swimming aid that can improve swimming speed. Background Art

[0002] In swimming and underwater activities, swimming aids can play an important role. A swimming aid refers to equipment designed to help swimmers improve swimming efficiency, enhance the swimming experience, or assist special personnel in swimming activities. Common ones include flippers, paddles, hand fins, etc. They are designed to increase the water contact area of the swimmer's limbs and use the reaction force of the water to push the body forward. At the same time, they can also help swimmers better master balance and control direction to a certain extent, improving the safety and fun of swimming.

[0003] However, existing swimming aids have many defects and are difficult to meet people's needs for improving swimming speed. Taking flippers as an example, they are widely used swimming aids that mainly increase the propulsion force during swimming by increasing the contact area between the feet and water. But when using flippers, most rely on the up-and-down swing of the sole to gain speed. This method requires certain skills and is laborious to use, making the user easily fatigued, resulting in limited and non-sustainable improvement in swimming speed. To improve swimming speed, Patent No. 201420835984.0 discloses a pair of swimming flippers that obtain a large water reaction force through the expansion and contraction of the flipper body to push the human body forward. When in use, there is no need to swing the sole back and forth, the feet are more comfortable, the forward movement is smoother, and physical strength is saved. Moreover, the user can also use it when standing in the water, that is, for treading water. However, in this design, the expansion amplitude of the flipper body depends on the traction of the central disc and the tensile rope, the structure is relatively complex, and when in use, the tensile rope is subjected to repeated impact tensile forces, resulting in the easy breakage of the tensile rope. After breaking, it is difficult to repair, increasing the use cost. Summary of the Invention

[0004] The object of the present invention is to solve the above technical problems and provide a swimming aid that can improve swimming speed with a simple, firm and easy-to-maintain structure.

[0005] To achieve the above object, the technical solution of the present invention is as follows: A swimming auxiliary device capable of improving swimming speed comprises a body connection piece for connecting and binding with a body part, and also comprises a limiting head in a disc structure, wherein a plurality of hinged seats and a plurality of ribs are arranged below the limiting head, wherein the plurality of hinged seats and the plurality of ribs are all distributed in a radial circle with the central axis of the limiting head as the center, and the distribution orientation of each hinged seat corresponds to that of each rib one by one; a rotating shaft is arranged at the inner end of each rib, and then the rib is rotatably arranged on the corresponding hinged seat through the rotating shaft, so that the rib can be opened upward or folded downward with the rotating shaft as the rotating point; when the rib is opened upward and abuts against the lower edge of the limiting head, the opening angle of the rib is the largest; an umbrella film is fixedly connected between adjacent ribs, and the umbrella film can be opened or folded in conjunction with the ribs, and the inner edge of the umbrella film should extend to the inside of the edge of the limiting head, so that the water flow can act on the umbrella film more effectively.

[0006] As a further technical solution, the position where the rib abuts against the lower edge of the limit head from the inner end of the rib should be no less than 1 / 4 of the length from the inner end of the rib to reduce the risk of the rib being broken by the impact of the water flow. The purpose is to reduce the bending moment of the rib and reduce the risk of it being broken when impacted by the water flow.

[0007] As a further technical solution, a circle of limiting protrusions is provided on the lower edge of the above-mentioned limiting head.

[0008] As a further technical solution, a conical head with a small upper part and a large lower part is connected to the upper part of the above-mentioned limit head, and a pull rod is provided at the central axis below the limit head. The upper end of the pull rod is connected to the lower surface of the limit head, and the lower end of the pull rod is connected to the body connector.

[0009] As a further technical solution, the above-mentioned body connecting piece is fixedly arranged on the upper surface of the limiting head.

[0010] The body connection member of the present invention can be a hand-held device, such as a ring handle, a cylindrical handle, etc., as long as it can be used in the market to achieve connection with body parts, it can be used in the present invention. The umbrella film material of the present invention is a conventional waterproof material with sufficient strength and flexibility. It is not a special design and is not specifically described here.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The structure of the present invention is simple, firm and easy to maintain.

[0012] By setting a limit head above the umbrella ribs, the present invention abandons the traditional complex tensile rope structure, simplifies the overall structure, and reduces the manufacturing difficulty and cost. This limit head can not only limit the maximum tension of the umbrella ribs, but also has the function of fixing the body connector. It can be used as a connector for foot covers, straps, handholds, etc., achieving dual use of one object, effectively improving the functionality and practicality of the device, better meeting the daily swimming needs, and facilitating user operation and carrying. The structure of the present invention is simple and firm, which can greatly extend the service life of the device, reduce the use cost and resource waste, and has good economic and practical value.

[0013] 2. The present invention can assist in increasing the swimming speed and adding the fun of swimming.

[0014] When in use, when the swimmer holds the swimming device of the present invention and stretches forward in the water, the umbrella ribs and umbrella membrane of the present invention are in a closed state under the action of water. When the swimmer pulls back the device of the present invention in the water, the umbrella ribs and umbrella membrane of the device of the present invention unfold under the action of water and reach the maximum open state when the umbrella ribs touch the back of the limit head, forming an effective resistance surface. At this time, the pulled-back device can provide a forward pulling force for the swimmer, thus easily increasing the swimming speed and bringing an interesting swimming experience to the swimmer.

[0015] 3. The present invention has diverse morphological choices.

[0016] By setting the body connector below or above the limit head, the present invention derives a pulling-in type or pushing type swimming device. This derivative design can be used not only by hand but also by putting it on (including tying it to) the feet. It gives the user more choices when swimming. Its diverse morphological choices greatly broaden the application scenarios of the product.

[0017] 4. The swimming device of the present invention is easy to use and not very laborious. When in use, only forward stretching and backward pulling (or backward pushing) of the hand, or closing and outward pushing of the feet are required, and it is very easy to master the usage method. Different from using fins, which requires practice to master the usage method of swinging up and down. Therefore, the present invention is easy to be promoted. Description of the Drawings

[0020] The present invention will be further described in detail below in conjunction with the embodiments, but the implementation manners of the present invention are not limited to the scope shown in the embodiments.

[0021] Embodiment 1: As Figures 1 to 4As shown, a hand-pull-in swimming auxiliary device for improving swimming speed includes a body connection part 1. In this embodiment, the body connection part 1 is an annular grip for hand-holding (it can also be a hand-held grip of other shapes), and also includes a disc-shaped limit head 2, and a conical head 7 with a small upper part and a large lower part is connected to the upper part of the limit head 2. The conical head 7 is conducive to reducing resistance when breaking through water and moving forward. A circle of limit protrusions 9 is provided on the lower edge of the limit head 2. A pull rod 8 is provided at the lower central axis of the limit head 2. The upper end of the pull rod 8 is connected to the lower surface of the limit head 2, and the lower end of the pull rod 8 is provided with an annular grip or a handle of other shapes; a plurality of hinged seats 3 and a plurality of ribs 4 are also provided below the limit head 2 (the actual number depends on the size of the product and the requirements of firmness). The number of the 8 ribs 4 is set to 8 for implementation description, but not for limitation of the protection scope of the present invention. The 8 articulated seats 3 and the 8 ribs 4 are all distributed in a radial circle with the central axis of the limit head 2 as the center, and the distribution orientation of each articulated seat 3 and each rib 4 corresponds to each other. A rotating shaft 5 is provided at the inner end of each rib 4, and then the rib 4 is rotated and set on the corresponding articulated seat 3 through the rotating shaft 5, so that the rib can be opened upward or folded downward with the rotating shaft 5 as the rotation point. When the rib 4 rotates upward and abuts against the lower edge of the limit head 2, the opening angle of the rib 4 is the largest. The adjacent ribs 4 are fixedly connected with umbrella films 6, and the connection method of the umbrella films 6 can be conventional methods such as bonding, sleeve connection, and binding, which will not be described in detail here. The umbrella film 6 can be opened or folded in conjunction with the rib 4. From the inner end of the rib 4, the position where the rib 4 abuts against the lower edge of the limit head 2 should be no less than 1 / 4 of the length from the inner end of the rib.

[0022] When in use, the swimmer holds the handle and pushes the device forward, and the ribs 4 and the umbrella membrane 6 are automatically folded under the action of the water flow, and the resistance to pushing forward is not large. When the swimmer pulls the device back, the ribs 4 and the umbrella membrane 6 are automatically unfolded by the impact of the water flow, and reach the maximum opening state when the ribs 4 touch the back of the limit head 2, forming a larger effective resistance surface. At this time, the device pulled back can provide the swimmer with a larger forward pulling force, thereby increasing the swimming speed.

[0023] Embodiment 2: like Figures 5 to 8As shown, a hand-propelled swimming auxiliary device for improving swimming speed includes a body connection part 1. In this embodiment, the body connection part 1 is an arc-shaped handle held by a hand (it can also be a handle of other shapes), and also includes a limit head 2 in a disc structure. Both ends of the arc-shaped handle are fixedly connected to the upper surface of the limit head 2. A plurality of hinge seats 3 and a plurality of ribs 4 are arranged below the limit head 2 (the actual number is set according to the size of the product and the requirements of the firmness. In this embodiment, the number is set to 8 for implementation description, but it is not a limitation of the protection scope of the present invention). These 8 hinge seats 3 and 8 ribs 4 are all distributed in a radial circle with the central axis of the limit head 2 as the center, and the distribution orientation of each hinge seat 3 and each rib 4 corresponds to each other; a rotating shaft 5 is provided at the inner end of each rib 4, and then the rib 4 is rotatably arranged on the corresponding hinge seat 3 through the rotating shaft 5, so that the rib can be opened upward or folded downward with the rotating shaft 5 as the rotation point; when the rib 4 is opened upward and abuts against the lower edge of the limit head 2, the opening angle of the rib 4 is the largest; an umbrella film 6 is fixedly connected between adjacent ribs 4, and the connection method of the umbrella film 6 can be conventional methods such as bonding, sleeve connection, and binding, which will not be described in detail here. The umbrella film 6 can be opened or folded in conjunction with the rib 4. Starting from the inner end of the rib 4, the position where the rib 4 abuts against the lower edge of the limit head 2 is not less than 1 / 4 of the length from the inner end of the rib 4.

[0024] When in use, the swimmer adopts a backstroke state, holds the arc-shaped handle, and pulls the device forward (toward the human head). At this time, the ribs 4 and the umbrella membrane 6 are automatically retracted under the action of the water flow, and the pulling force is small. When pushed backward (toward the human foot), the ribs 4 and the umbrella membrane 6 are automatically unfolded by the impact of the water flow, and reach the maximum opening state when the ribs 4 touch the back of the limit head 2, forming a larger effective resistance surface. At this time, the backward-pushing device can provide the swimmer with a larger forward thrust (toward the human head), thereby increasing the swimming speed.

[0025] Embodiment 3: like Figures 9 to 12As shown in the figure, a foot-propelled swimming aid that can improve swimming speed includes a body connector 1. In this embodiment, the body connector 1 is a foot sleeve (including straps) that is connected and bound to the feet. It also includes a limit head 2 in a disc structure. The foot sleeve and the straps are fixedly connected to the upper surface of the limit head 2. Below the limit head 2, there are several hinge seats 3 and several umbrella ribs 4 (the actual number is set according to the requirements of the product size. In this embodiment, the set number is 8 for illustrative purposes, but it is not a limitation of the protection scope of the present invention). These 8 hinge seats 3 and 8 umbrella ribs 4 are radially distributed in a circular pattern centered on the central axis of the limit head 2, and the distribution orientations of each hinge seat 3 and each umbrella rib 4 correspond one by one. At the inner end of each umbrella rib 4, there is a rotating shaft 5. Then, the umbrella rib 4 is rotatably arranged on the corresponding hinge seat 3 through the rotating shaft 5, so that the umbrella rib can open upward or close downward with the rotating shaft 5 as the rotation point. When the umbrella rib 4 opens upward and abuts against the lower edge of the limit head 2, the opening angle of the umbrella rib 4 is the largest. There is a fixed connection between adjacent umbrella ribs 4 with an umbrella membrane 6. The connection method of the umbrella membrane 6 can be conventional methods such as bonding, sleeving, tying, etc., and no more detailed description will be given here. The umbrella membrane 6 can be linked to open or close with the umbrella rib 4. Starting from the inner end of the umbrella rib 4, the position where the umbrella rib 4 abuts against the lower edge of the limit head 2 is at a length not less than 1 / 4 starting from the inner end of the umbrella rib 4.

[0026] When in use, the swimmer puts on the foot sleeve and fastens it to the feet with the straps. When the swimmer draws the legs in the water (towards the head of the human body), the umbrella ribs 4 and the umbrella membrane 6 automatically close under the action of the water flow. At this time, the resistance generated by the device is small. When kicking backward (towards the feet direction), the umbrella ribs 4 and the umbrella membrane 6 are automatically unfolded by the impact of the water flow and reach the maximum opening state when the umbrella ribs 4 touch the back of the limit head 2, forming a large effective resistance surface. At this time, the device pushed backward can provide a large forward thrust to the swimmer, thereby improving the swimming speed.
