Abstract
Description
Technical Field
[0001] The utility model relates to a kayak, in particular to a double-chamber side-gunwale kayak. Background Art
[0002] The buoyancy of traditional kayaks mainly comes from a single chamber at the bottom, which is usually made of materials such as hard plastic, fiberglass or carbon fiber. During use, the following problems exist. Firstly, there is the problem of stability. Since the chamber of traditional single-chamber kayaks is only located at the bottom, when traveling in complex waters, such as rapids and shoals, it is prone to capsizing. Secondly, there is the problem of load-bearing capacity. Due to the limited area of the chamber in traditional single-chamber kayaks, the carrying capacity and cargo capacity are restricted to a certain extent. Therefore, traditional single-chamber kayaks need to be further improved to better meet the requirements of various application scenarios. Content of the Utility Model

[0008] Furthermore, two L-shaped brackets are arranged on the upper end surface of the main chamber, the opening directions of the two L-shaped brackets are the same, and the two L-shaped brackets are respectively arranged on both sides of the seat to limit the oars.
[0009] Furthermore, the main chamber is in a cuboid shape and runs through the hull along the length direction of the hull.

[0019] The following further elaborates on the utility model in detail in conjunction with the drawings and specific embodiments.
[0020] The utility model provides a double-chamber side hull kayak, designed to improve the stability and load-bearing capacity of the hull. The specific embodiments are as Figures 1-3 shown:
[0021] In terms of the hull structure design: As shown in Figure 1 and 2 shown, the hull 100 includes a main chamber 110 and two auxiliary chambers 120. The main chamber 110 runs through along the length direction of the hull 100 and is embedded with a seat 200. The auxiliary chambers 120 are evenly distributed on both sides of the hull 100, forming an enclosure around the main chamber 110.
[0022] In terms of the stability design: A double-chamber structure is adopted: The main chamber 110 and the auxiliary chamber 120 form a double-chamber structure, which improves the stability of the hull. When encountering lateral water flow impact, they do not affect each other, reducing the risk of overturning. The position layout of the main chamber 110 helps to lower the center of gravity of the hull and increase the stability during water travel.
[0023] In terms of the structural reinforcement design: As shown in Figure 3As shown, a reinforcing sheet 600 is attached to the surface of the bottom connection of the auxiliary air chamber 120, and the reinforcing sheet 600 extends from the head to the tail of the hull 100. This enhances the integrity of the bottom of the hull and improves the stability when carrying heavy loads. Anti-collision ridges 300 are provided on the outer edges of the two side auxiliary air chambers 120, and the anti-collision ridges 300 are arranged in the middle of the side hull along the length direction of the hull 100. The anti-collision ridges 300 adopt a V-shaped longitudinal section design and are arranged in the middle of the side hull along the length direction of the hull 100, which can effectively disperse the external impact force, enhance the structural strength of the hull, and improve the stability.
[0024] In addition, two L-shaped brackets 500 are provided on the upper end surface of the main air chamber. The opening directions of the two L-shaped brackets are the same, and the two L-shaped brackets are respectively arranged on both sides of the seat to limit the oars, which is convenient for fixing the oars on the hull when resting. Air valves 400 are independently provided on the main air chamber 110 and the auxiliary air chamber 120 respectively, and the design allows the operator to independently inflate each air chamber.
[0025] The above-mentioned rubber material inflatable boats and PVC material inflatable boats.
[0026] From the aspect of the hull structure, the design of the double-air-chamber side hull kayak makes the center of gravity of the hull lower. The air chamber of the original single-air-chamber kayak is usually located in the center of the hull, while on the basis of the original single-air-chamber, two side hull air chambers are added to the double-air-chamber side hull kayak. These two side hull air chambers are evenly distributed on both sides of the hull, making the overall weight distribution of the hull more uniform and reducing the center of gravity of the hull. The lower center of gravity means that when traveling in water, the hull is more stable and the anti-overturning ability is significantly improved.
[0027] In summary, on the basis of the original single-air-chamber, the double-air-chamber side hull kayak has successfully reduced the center of gravity of the hull and improved the stability by adding side hull air chambers and optimizing the hull structure. At the same time, the design of the added air chambers and reinforcing sheets has significantly improved the load-bearing capacity of the hull. This design not only improves the practicality of the kayak, but also greatly enriches the types of water sports equipment, providing more choices for consumers.
[0028] The above embodiments are not limitations on the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the technical scope of the present invention also fall within the protection scope of the present invention.
