Description

Technical Field

[0001] This utility model belongs to the field of sports equipment, specifically relating to a swimming aid that can improve swimming speed. Background Technology

[0002] Swimming aids play a vital role in swimming and underwater activities. Swimming aids are equipment designed to help swimmers improve swimming efficiency, enhance the swimming experience, or assist individuals with special needs in swimming. Common examples include fins, pads, and wrists. These devices aim to increase the surface area of ​​the swimmer's limbs for paddling, using the reaction force of the water to propel the body forward. They also help swimmers maintain balance and control direction, thus improving the safety and enjoyment of swimming.

[0003] However, existing swimming aids have many shortcomings and fail to meet people's needs for increased swimming speed. Take fins as an example; they are widely used swimming aids, primarily increasing the contact area between the foot and water to enhance propulsion during strokes. However, using fins mostly relies on the up-and-down movement of the foot to gain speed, which requires certain skills and is quite strenuous, leading to user fatigue and limited, unsustainable speed gains. To improve swimming speed, patent number 201420835984.0 discloses a swimming fin that uses the extension and contraction of the fin body to generate greater water reaction force, propelling the body forward. It eliminates the need for back-and-forth foot movements, making the feet more comfortable, propulsion smoother, and energy-saving. It can also be used while standing in the water, i.e., for treading water. However, in this design, the extension range of the fin body depends on the traction of the central disc and the tension rope, resulting in a complex structure. Furthermore, the tension rope is subjected to repeated impact tension during use, making it prone to breakage and difficult to repair, increasing usage costs. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned technical problems and provide a swimming aid that is simple, sturdy, and easy to maintain, and can improve swimming speed.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A swimming aid for improving swimming speed includes a body connector for attaching to and binding with body parts, and a disc-shaped limiting head. Below the limiting head are several hinge seats and several umbrella ribs, all radially distributed around the central axis of the limiting head, with each hinge seat corresponding to one of the umbrella ribs. Each umbrella rib has a pivot at its inner end, allowing it to rotate and be mounted on its corresponding hinge seat, enabling it to open upwards or close downwards. The opening angle of the umbrella rib is maximized when it is open upwards and abuts against the lower edge of the limiting head. A membrane is fixedly connected between adjacent umbrella ribs, opening and closing in tandem with the ribs. The inner edge of the membrane extends into the edge of the limiting head, allowing water flow to act more effectively on the membrane.

[0007] As a further technical solution, the position where the umbrella rib abuts against the lower edge of the limiting head, starting from the inner end of the umbrella rib, should be no less than 1 / 4 of the length starting from the inner end of the umbrella rib, in order to reduce the risk of the umbrella rib breaking due to water flow impact. The purpose is to reduce the bending moment on the umbrella rib and reduce the risk of it breaking when impacted by water flow.

[0008] As a further technical solution, the lower edge of the aforementioned limiting head is provided with a ring of limiting protrusions.

[0009] As a further technical solution, a tapered head with a smaller upper part and a larger lower part is connected above the aforementioned limiting head, and a pull rod is provided at the lower central axis of the limiting head. The upper end of the pull rod is connected to the lower surface of the limiting head, and the lower end of the pull rod is connected to the body connector.

[0010] As a further technical solution, the body connector described above is fixedly mounted on the upper surface of the limiting head.

[0011] The body connector of this utility model can be a hand grip device, such as a ring handle, a cylindrical handle, etc. Any commercially available material suitable for connection to a body part can be used in this utility model. The umbrella membrane material of this utility model is a conventional waterproof material with sufficient strength and flexibility; it is not a special design and will not be specifically described here.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model has a simple and robust structure and is easy to maintain.

[0014] This invention eliminates the need for a traditional, complex tensile rope structure by incorporating a limiting head above the umbrella ribs, simplifying the overall construction and reducing manufacturing difficulty and cost. This limiting head not only limits the maximum tension of the umbrella ribs but also functions as a body connector, serving as a link for foot covers, straps, and hand grips, achieving dual functionality and effectively enhancing the equipment's practicality. It better meets the needs of daily swimming and is easy for users to operate and carry. This invention features a simple yet robust structure, significantly extending the equipment's lifespan, reducing usage costs and resource waste, and possessing excellent economic and practical value.

[0015] 2. This utility model can help improve swimming speed and increase the fun of swimming.

[0016] When in use, the swimmer extends the umbrella-shaped swimming device forward in the water, causing the ribs and membrane to close under the influence of water. When the swimmer pulls the device back in the water, the ribs and membrane expand under the influence of water, reaching their maximum opening when the ribs touch the back of the limiting head, creating an effective resistance surface. At this point, pulling back provides the swimmer with a forward pulling force, easily increasing swimming speed and providing a more enjoyable swimming experience.

[0017] 3. This utility model has a variety of form options.

[0018] This invention, by placing the body connector below or above the limiting head, creates a pull-in or propulsion type swimming device. This derivative design allows for both handheld and foot-mounted (including strapped) use, providing users with more options when swimming. Its diverse form options greatly broaden the product's application scenarios.

[0019] 4. The swimming apparatus of this invention is simple to use and requires minimal effort. Users only need to extend their hands forward and pull back (or push backward), or tuck their feet in and push them outward, making it extremely easy to master. Unlike fins, which require practice to master the up-and-down motion, this invention is easily promoted. Attached Figure Description

[0033] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited to the scope shown in the embodiments.

[0034] Example 1:

[0035] like Figures 1-4As shown, a hand-pulled swimming aid that can improve swimming speed includes a body connector 1. In this embodiment, the body connector 1 is a ring-shaped grip for hand use (or other shaped hand grips). It also includes a disc-shaped limiting head 2. A conical head 7 with a smaller top and larger bottom is connected to the upper part of the limiting head 2. The conical head 7 helps to reduce resistance when breaking through the water. A ring of limiting protrusions 9 is provided on the lower edge of the limiting head 2. A pull rod 8 is provided at the lower central axis of the limiting head 2. The upper end of the pull rod 8 is connected to the lower surface of the limiting head 2, and the lower end of the pull rod 8 is provided with a ring-shaped grip or other shaped handle. Several hinge seats 3 and several umbrella ribs 4 are also provided below the limiting head 2 (the actual number depends on the size of the product and the requirements for sturdiness). In this embodiment, the number of hinge seats 3 and 8 umbrella ribs 4 are set in a radial circular pattern around the central axis of the limiting head 2, and the distribution orientation of each hinge seat 3 corresponds one-to-one with that of each umbrella rib 4. Each umbrella rib 4 has a rotating shaft 5 at its inner end, allowing it to rotate and be mounted on the corresponding hinge seat 3, enabling it to open upwards or close downwards. The opening angle of the umbrella rib 4 is at its maximum when it rotates upwards and abuts against the lower edge of the limiting head 2. Adjacent umbrella ribs 4 are fixedly connected with umbrella membranes 6, which can be connected by conventional methods such as bonding, sleeve joining, or binding, which will not be described in detail here. The umbrella membranes 6 can open or close in conjunction with the umbrella ribs 4. From the inner end of the umbrella rib 4, the position where the umbrella rib 4 abuts against the lower edge of the limiting head 2 should be no less than 1 / 4 of its length from the inner end of the umbrella rib.

[0036] When in use, the swimmer holds the handle and pushes the device forward. The umbrella ribs 4 and umbrella membrane 6 automatically retract under the action of the water flow, and the resistance to pushing forward is not significant. When the swimmer pulls the device backward, the umbrella ribs 4 and umbrella membrane 6 automatically unfold due to the impact of the water flow, reaching their maximum open state when the umbrella ribs 4 touch the back of the limiting head 2, forming a larger and more effective resistance surface. At this time, the device can provide the swimmer with a greater forward pulling force, thereby increasing swimming speed.

[0037] Example 2:

[0038] like Figures 5-8As shown, a hand-propelled swimming aid that can improve swimming speed includes a body connector 1. In this embodiment, the body connector 1 is an arc-shaped handle for hand gripping (it can also be a handle of other shapes). It also includes a limiting head 2 with a disc structure. The two ends of the arc-shaped handle are fixedly connected to the upper surface of the limiting head 2. Below the limiting head 2, there are several hinge seats 3 and several umbrella ribs 4 (the actual number is set according to the size of the product and the requirements for sturdiness. In this embodiment, the number is set to 8 for implementation purposes, but it is not a limitation of the scope of protection of this utility model). These 8 hinge seats... The hinge seat 3 and the eight umbrella ribs 4 are radially distributed around the central axis of the limiting head 2, and the distribution orientation of each hinge seat 3 corresponds one-to-one with that of each umbrella rib 4. Each umbrella rib 4 has a pivot 5 at its inner end, allowing the rib 4 to rotate and be mounted on the corresponding hinge seat 3, enabling it to open upwards or close downwards using the pivot 5 as the rotation point. The opening angle of the umbrella rib 4 is at its maximum when it opens upwards and abuts against the lower edge of the limiting head 2. Adjacent umbrella ribs 4 are fixedly connected by an umbrella membrane 6, which can be connected using conventional methods such as adhesive bonding, sleeve bonding, or binding, which will not be elaborated upon here. The umbrella membrane 6 opens or closes in conjunction with the umbrella ribs 4. The position where the umbrella rib 4 abuts against the lower edge of the limiting head 2, starting from its inner end, is at least 1 / 4 of its length from the inner end of the umbrella rib 4.

[0039] When in use, the swimmer adopts a backstroke position, grips the curved handle, and pulls the device forward (towards the head). At this time, the umbrella ribs 4 and umbrella membrane 6 automatically close under the action of the water flow, and the pulling force is small. When pushing backward (towards the feet), the umbrella ribs 4 and umbrella membrane 6 automatically unfold under the impact of the water flow, reaching their maximum opening state when the umbrella ribs 4 touch the back of the limiting head 2, forming a larger and more effective resistance surface. At this time, the device can provide the swimmer with a greater forward thrust (towards the head), thereby increasing swimming speed.

[0040] Example 3:

[0041] like Figures 9-12As shown, 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 cover (including straps) that is connected and bound to the feet. It also includes a limiting head 2 with a disc structure. The foot cover and straps are fixedly connected to the upper surface of the limiting head 2. Below the limiting head 2, there are several hinge seats 3 and several umbrella ribs 4 (the actual number is set according to the size requirements of the product. In this embodiment, the number is set to 8 for implementation purposes, but it is not a limitation of the scope of protection of this utility model). These 8 hinge seats 3 and 8 umbrella ribs The ribs 4 are radially distributed around the central axis of the limiting head 2, and the orientation of each hinge seat 3 corresponds one-to-one with the distribution of each rib 4. Each rib 4 has a pivot 5 at its inner end, allowing the rib 4 to rotate and be mounted on the corresponding hinge seat 3, enabling it to open upwards or close downwards using the pivot 5 as the rotation point. The opening angle of the rib 4 is at its maximum when it opens upwards and abuts against the lower edge of the limiting head 2. Adjacent ribs 4 are fixedly connected by a membrane 6, which can be connected using conventional methods such as adhesive bonding, sleeve bonding, or binding; these will not be discussed in detail here. The membrane 6 opens or closes in conjunction with the ribs 4. The position where the rib 4 abuts against the lower edge of the limiting head 2, starting from its inner end, is at least 1 / 4 of its length from the inner end of the rib 4.

[0042] When in use, swimmers wear foot covers and secure them to their feet with straps. When pulling their legs in the water (towards the head), the umbrella ribs 4 and umbrella membrane 6 automatically close under the influence of the water flow, resulting in minimal resistance. When kicking backward (towards the feet), the umbrella ribs 4 and umbrella membrane 6 automatically unfold due to the impact of the water flow, reaching their maximum opening state when the umbrella ribs 4 touch the back of the limiting head 2, forming a larger and more effective resistance surface. At this point, the backward push of the device provides the swimmer with a greater forward thrust, thereby increasing swimming speed.
