Description

Technical Field

[0001] This invention relates to inflatable products, and more particularly to an inflatable water sports device and its manufacturing method. Background Technology

[0002] Inflatable water sports equipment is popular for its portability, durability, and ease of storage. Designed for activities such as paddleboarding, kayaking, rafting, and recreational floating, these products offer a convenient alternative to traditional rigid equipment while maintaining high performance and safety standards.

[0003] For example, paddleboarding typically involves using paddles to propel a board forward in the water. These sports are enjoyed by people of all ages and skill levels and can be performed in a variety of water environments, from calm lakes to ocean waves. In recent years, inflatable paddleboards have become increasingly popular due to their several advantages over traditional hard-shell boards. When deflated, inflatable paddleboards roll into a compact package that easily fits into a backpack, making them ideal for users who want to carry their paddleboard with them. This portability eliminates the need for roof racks to transport the paddleboard to the beach or lake.

[0004] However, existing inflatable paddleboards and other water sports equipment have a drawback: additional layers, such as EVA padding, are glued to the surface of the paddleboard to improve its anti-slip performance. However, the bottom of the EVA padding is smooth, and directly gluing it to the smooth surface of the paddleboard has many disadvantages. For example, the adhesive structure between the EVA padding and the paddleboard surface is easily damaged by prolonged immersion in water and exposure to sunlight, resulting in bulging and glue peeling. Summary of the Invention

[0005] One advantage of this invention is that it provides an inflatable water sports device and its manufacturing method, which uses an adhesive layer to firmly attach the pad to the inflatable body of the inflatable water sports device, reducing the occurrence of bulging and glue peeling, and improving the service life of the inflatable water sports device.

[0006] Another advantage of this invention is that it provides an inflatable water sports device and a method for manufacturing the same, wherein an adhesive layer is added between the padding layer and the inflatable body to increase adhesion. This layer ensures that the adhesive is evenly distributed on the inflatable body and the padding layer by providing a more stable bonding surface for the adhesive. The adhesive layer acts similarly to adding a base coat, creating stronger adhesion and increasing bond strength between the two surfaces. This allows for more uniform application, ensuring the padding layer remains firmly bonded without weak points or inconsistencies during the bonding process.

[0007] Another advantage of this invention is that it provides an inflatable water sports device and a method for manufacturing the same, wherein the risk of separation, particularly along the edges, is significantly reduced by adding an adhesive layer. This innovation enhances the integrity of the bond and prevents premature peeling, ensuring that the padding layer remains firmly in place throughout its service life.

[0008] Another advantage of this invention is that it provides an inflatable water sports device and a method of manufacturing the same, wherein the adhesive layer helps improve the overall durability of the inflatable water sports device by generating stronger adhesion and ensuring more uniform application of the adhesive. The padding layer not only maintains a strong bond, but the inflatable water sports device will also better withstand wear and tear from daily use, including contact with water, ultraviolet light, dragging abrasion, and exposure to different temperatures. As a result, the product can withstand long-term use, thereby reducing the need for repair or replacement due to adhesive failure.

[0009] Another advantage of this invention is that it provides an inflatable water sports device and a method of manufacturing the same, wherein the improved adhesion between the pad and the inflatable body enhances the user experience by ensuring a safer and more durable inflatable water sports device. Users are less likely to encounter problems such as a loose pad or discomfort due to bumpy or uneven surfaces. This contributes to a more comfortable and enjoyable experience for users, especially when traction and stability are critical.

Detailed Implementation

[0067] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0068] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0069] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0070] This invention provides an inflatable water sports device, which can be an inflatable paddleboard, inflatable floating platform, inflatable fishing float or platform, inflatable kayak, inflatable dog ladder or ramp, inflatable seat, inflatable sofa, inflatable aerobics mat, inflatable yoga mat, inflatable tent, or inflatable bed. In this invention, a padding layer, such as an anti-slip layer, seat layer, standing layer, or abrasion-resistant pad, is firmly attached to the inflatable body of the inflatable water sports device by means of an adhesive layer to increase the absorption capacity of the adhesive, thereby strengthening the adhesion between materials. The increased friction enhances the adhesive strength and reduces common problems such as edge delamination and bubbling in stress areas.

[0071] See appendix Figures 1 to 5C The illustration shows an inflatable paddleboard according to a preferred embodiment of the present invention, the inflatable paddleboard including an inflatable body 10, an adhesive layer 20 and a padding layer 30, wherein the adhesive layer 20 is disposed between the top surface 11 of the inflatable body 10 and the padding layer 30.

[0072] In this embodiment, the padding layer 30 is an anti-slip layer for the swimmer to stand on, having an anti-slip top surface 31 and a bottom surface 32, wherein the bottom surface 32 of the padding layer 30 is adhered to the adhesive layer 20. More specifically, the adhesive layer 20 has a first side 21 and a second side 22, wherein the bottom surface 32 of the padding layer 30 is adhered to the first side 21 of the adhesive layer 20, and the second side 22 of the adhesive layer 20 is adhered to the top surface 11 of the inflatable body 10.

[0073] Compared to the top surface 11 of the inflatable body 10 and the bottom surface 32 of the padding layer 30, the adhesive layer 20 has better adhesive-holding ability, allowing the adhesive to adhere more firmly to the adhesive layer 20. Because the adhesive between the padding layer 30 and the inflatable body 10 is firmly adhered to the adhesive layer 20, the adhesive between the padding layer 30 and the inflatable body 10 can be applied more evenly and has better adhesion.

[0074] Specifically, the adhesive layer 20 is preferably made of a flexible material, more preferably of a mesh fabric, such as a network composed of fibers or threads, typically having a woven or knitted structure. The material of the adhesive layer 20 is selected from nylon, polyester, polypropylene, polyurethane, polyester and rubber threads, carbon fiber, aramid fiber, PTFE (polytetrafluoroethylene), natural fibers, glass fiber, HDPE (high-density polyethylene), and PEEK (polyetheretherketone). Part of the adhesive applied to the adhesive layer 20 is absorbed into the adhesive layer 20, thus easily preventing unnecessary flow of the adhesive applied to the adhesive layer 20. Under the adsorption effect of the adhesive layer 20, the adhesive between the padding layer 30 and the inflatable body 10 can be applied more evenly. On the other hand, the adhesive layer 20 can accommodate more adhesive between the padding layer 30 and the inflatable body 10, making the bond between the padding layer 30 and the inflatable body 10 stronger and reducing the occurrence of bulging, adhesive cracking, and other phenomena.

[0075] See appendix Figures 4 to 5C The inflatable paddleboard also includes a first adhesive coating 40 formed by a first adhesive 401 and a second adhesive coating 50 formed by a second adhesive 501. The first adhesive coating 40 is applied to one side of the adhesive layer 20. The padding layer 30 covers the first adhesive coating 40, so that the first adhesive coating 40 firmly bonds the adhesive layer 20 and the padding layer 30 together. It is worth mentioning that, because the adhesive layer 20 has adhesive-holding ability, the first adhesive coating 40 is partially embedded in the adhesive layer 20, so that the first adhesive coating 40 can be firmly adhered to the adhesive layer 20, and the first adhesive coating 40 is evenly applied to the adhesive layer 20, so that the first adhesive coating 40 can be more firmly adhered to the padding layer 30, making the adhesion between the padding layer 30 and the adhesive layer 20 stronger. In detail, since the adhesive layer 20 has the ability to hold adhesive, the first adhesive coating layer 40 will be partially embedded in the adhesive layer 20, so that the first adhesive coating layer 40 is firmly bonded to the adhesive layer 20. The first adhesive coating layer 40 will be evenly coated on the adhesive layer 20, so that the first adhesive coating layer 40 and the padding layer 30 are bonded more firmly, thereby making the bond between the padding layer 30 and the adhesive layer 20 stronger.

[0076] The second adhesive coating 50 covers the padding area 111 of the top surface 11 of the inflatable body 10, and is applied to the adhesive layer 20. In other words, the second adhesive coating 50 extends between the padding area 111 of the top surface 11 of the inflatable body 10 and the adhesive layer 20, so as to firmly bond the adhesive layer 20 to the inflatable body 10. It is worth mentioning that, due to the adhesive-holding ability of the adhesive layer 20, the second adhesive coating 50 is also partially embedded in the adhesive layer 20, so that the second adhesive coating 50 is firmly bonded to the adhesive layer 20, and the second adhesive coating 50 extends evenly to the adhesive layer 20, so that the thickness of the second adhesive coating 50 can be formed to be thicker, making the second adhesive coating 50 adhere more firmly to the padding layer 30, thereby making the adhesion between the top surface 11 of the inflatable body 10 and the adhesive layer 20 more secure. In detail, since the adhesive layer 20 has adhesive-holding ability, the second adhesive coating layer 50 is partially embedded in the adhesive layer 20, so that the second adhesive coating layer 50 is firmly bonded to the adhesive layer 20. The second adhesive coating layer 50 is evenly coated on the adhesive layer 20, so that the thickness of the second adhesive coating layer 50 can be thicker than that formed directly on the bottom surface 32 of the pad 30, making the second adhesive coating layer 50 bond to the pad 30 more firmly, and making the adhesion between the pad 30 and the adhesive layer 20 stronger.

[0077] The adhesive layer 20 preferably has a plurality of mesh openings 201 for the adhesive to enter, so that the first adhesive coating layer 40 and the second adhesive coating layer 50 formed by the adhesive can be inserted into the mesh openings 201 and uniformly formed with the adhesive layer 20, so that the adhesive coating is more uniform.

[0078] It is worth mentioning that the first adhesive coating 40 can be bonded to the second adhesive coating 50 within the mesh 201, so that the first adhesive coating 40 and the second adhesive coating 50 cooperate to form a more robust adhesive structure.

[0079] The adhesion between the padding layer 30 and the inflatable body 10 is improved, making it more resistant to environmental stresses such as water, UV radiation, and temperature changes. This reduces material degradation and significantly extends service life. Users can enjoy a more reliable and longer-lasting experience without worrying about premature wear common in traditional pads or mats.

[0080] The mesh layer enhances the adhesive's grip, ensuring more uniform application and bonding between the padding layer 30 and the inflatable body 10. This minimizes the risk of separation, especially at the edges, and significantly reduces the likelihood of blistering or foaming in high-pressure areas. This means the product will maintain its structural integrity under harsh conditions, even with frequent exposure to water or outdoor environments.

[0081] With enhanced grip, users will experience a smoother, more consistent feel under their feet and during use. The improved anti-slip surface provides added safety and stability, which is especially important for water sports equipment where balance and traction are crucial. Furthermore, the overall feel of the product will be more comfortable, resulting in a more enjoyable user experience.

[0082] According to this preferred embodiment, the second adhesive 501 constituting the second adhesive coating 50 is mainly composed of polyurethane resin, such as a mixture of acetone, xylene, methyl ethyl ketone (MEK), methyl acetate, and polyurethane resin, wherein the mass ratio of acetone, xylene, MEK, methyl acetate, and polyurethane resin is: acetone 18%–30%, xylene 20%–25%, MEK 15%–25%, methyl acetate 7%–15%, and polyurethane resin 15%–20%. The first adhesive 401 constituting the first adhesive coating 40 is mainly composed of polyurethane resin, such as a mixture of acetone, xylene, MEK, methyl acetate, and polyurethane resin, wherein the mass ratio of acetone, xylene, MEK, methyl acetate, and polyurethane resin is: acetone 18%–30%, xylene 20%–25%, MEK 15%–25%, methyl acetate 7%–15%, and polyurethane resin 15%–20%.

[0083] According to an optional embodiment of the present invention, the second adhesive 501 constituting the second adhesive coating 50 and the first adhesive 401 constituting the first adhesive coating 40 are chloroprene rubber-based adhesives, such as a mixture of acetone, methyl ethyl ketone, methyl acetate and chloroprene rubber.

[0084] The second adhesive 501 forming the second adhesive coating 50 and the first adhesive 401 forming the first adhesive coating 40 can be the same adhesive material. According to an alternative embodiment of this preferred embodiment, the second adhesive 501 forming the second adhesive coating 50 and the first adhesive 401 forming the first adhesive coating 40 are different adhesives, such that the second adhesive 501 forming the second adhesive coating 50 is more suitable for the material of the top surface 11 of the inflatable body 10, while the first adhesive 401 forming the first adhesive coating 40 is more suitable for the material of the bottom surface 32 of the padding layer 30. For example, the first adhesive 401 is a polyurethane resin-based adhesive, and the second adhesive 501 is a neoprene rubber-based adhesive.

[0085] According to this preferred embodiment, the material of the padding layer 30 is EVA (ethylene-vinyl acetate). Alternatively, the padding layer 30 can be TPE (thermoplastic elastomer), rubber, polyurethane, rubberized EVA, or neoprene. The material of the top surface 11 of the inflatable body 10 is PVC (polyvinyl chloride) or TPU (thermoplastic polyurethane rubber). Therefore, the inflatable body 10 is made of a filamentous material formed by two layers of surface material interconnected by a plurality of vertical lines, and the top surface 11 is typically PVC or TPU.

[0086] See Figures 5A to 5CAccording to the first manufacturing method of the inflatable paddleboard of the above preferred embodiment of the present invention, the manufacturing method includes the following steps:

[0087] (A) The inflatable body 10 that forms the inflatable paddleboard;

[0088] (B) Apply the first adhesive 401 to the bottom surface 32 of the pad 30;

[0089] (C) The adhesive layer 20 is attached to the bottom surface 32 of the pad 30 coated with the first adhesive 401, wherein the first side 21 of the adhesive layer 20 is attached to the bottom surface 32 of the pad 30 by the first adhesive 401, wherein the first adhesive 401 is partially embedded in the mesh 201 of the mesh fabric of the adhesive layer 20.

[0090] (D) Apply a second adhesive 501 to the second side 22 of the adhesive layer 20;

[0091] (E) Apply the second adhesive 501 to the padding area 111 on the top surface 11 of the inflatable body 10;

[0092] (F) The second adhesive 501 applied to the inflatable body 10 and the second adhesive 501 applied to the adhesive layer 20 are dried;

[0093] (G) The pad 30 with the adhesive layer 20 is attached to the top surface 11 of the inflatable body 10, such that the second side of the adhesive layer 20 is attached to the pad area 111 of the top surface 11 of the inflatable body 10, so as to form a second adhesive layer 50 between the adhesive layer 20 and the top surface 11 of the inflatable body 10.

[0094] In this embodiment, the first adhesive 401 is applied to the bottom surface 32 of the padding layer 30. Through the adhesive effect of the first adhesive 401, the adhesive layer 20 and the padding layer 30 are bonded together to form a first adhesive coating 40 that extends uniformly between the adhesive layer 20 and the padding layer 30. Specifically, one side of the first adhesive coating 40 is adhered to the bottom surface 32 of the padding layer 30, and the other side of the first adhesive coating 40 is adhered to the first side 21 of the adhesive layer 20.

[0095] Understandably, during production, the padding layer 30 can be conveyed through a rotating roller coated with a first adhesive 401, causing the first adhesive 401 to be applied to the bottom surface 32 of the padding layer 30. Then, the padding layer 30 coated with the first adhesive 401 and the adhesive layer 20 are pressed together through the gap between a pair of pressure rollers, thereby bonding the padding layer 30 and the adhesive layer 20 together through the first adhesive 401. These pressure rollers can be heated to increase the tackiness of the first adhesive 401 and enhance the bond strength between the padding layer 30 and the adhesive layer 20.

[0096] Then, a second adhesive 501 is applied to the second side 22 of the adhesive layer 20, and also to the padding area 111 on the top surface 11 of the inflatable body 10. When the adhesive layer is a mesh fabric with fine mesh openings 201, when the second adhesive 501 is applied to the second side 22 of the adhesive layer 20, the second adhesive 501 will enter the mesh openings 201 from the second side 22 of the adhesive layer 20 and merge with the first adhesive coating layer 40 within the mesh openings 201, thereby bonding with the first adhesive coating layer 40.

[0097] Before attaching the adhesive layer 20 to the top surface 11 of the inflatable body 10, the second adhesive 501 is dried under the following conditions: drying temperature of 15-30 degrees Celsius and drying time of 10-1000 minutes.

[0098] After the adhesive layer 20 and the second adhesive 501 applied to the inflatable body 10 are dried under the above-mentioned drying conditions, the pad 30 with the adhesive layer 20 is attached to the top surface 11 of the inflatable body 10, so that the second side 22 of the adhesive layer 20 is attached to the padding area 111 of the top surface 11 of the inflatable body 10, thereby forming a second adhesive coating 50 between the adhesive layer 20 and the padding area 111 of the top surface 11 of the inflatable body 10.

[0099] See appendix Figure 6A and 6B According to an alternative approach, the method for manufacturing an inflatable paddleboard according to the above-described preferred embodiment of the present invention includes the following steps:

[0100] (a) The inflatable body 10 that forms the inflatable paddleboard;

[0101] (b) Apply the first adhesive 401 to the first side 21 of the adhesive layer 20;

[0102] (c) Apply the second adhesive 501 to the second side 22 of the adhesive layer 20;

[0103] (d) Apply the second adhesive 501 to the padding area 111 on the top surface 11 of the inflatable body 10;

[0104] (e) The second adhesive 501 applied to the inflatable body 10, the second adhesive 501 applied to the adhesive layer 20, and the first adhesive 401 applied to the adhesive layer 20 are dried.

[0105] (f) The padding layer 30 is attached to the first side 21 of the adhesive layer 20 with the first adhesive 401 to form a first adhesive layer 40 on the top surface 11 of the inflatable body 10, and the second side 22 of the adhesive layer 20 is attached to the padding area 111 on the top surface 11 of the inflatable body 10 to form a second adhesive layer 50 between the adhesive layer 20 and the top surface 11 of the inflatable body 10.

[0106] In this embodiment, the first adhesive 401 is applied to the first side 21 of the adhesive layer 20, the second adhesive 501 is applied to the second side 22 of the adhesive layer 20, and the second adhesive 501 is applied to the padding area 111 on the top surface 11 of the inflatable body 10.

[0107] Before attaching the adhesive layer 20 to the top surface 11 of the inflatable body 10 and the bottom surface 32 of the padding layer 30, the first adhesive 401 and the second adhesive 501 are dried under the following conditions: drying temperature of 15-30 degrees Celsius and drying time of 10-100 minutes.

[0108] After the second adhesive 501 applied to the adhesive layer 20, the second adhesive 501 applied to the inflatable body 10, and the first adhesive 401 applied to the bottom surface 32 of the padding layer 30 are dried under the aforementioned drying conditions, the padding layer 30 is adhered to the first side 21 of the adhesive layer 20 by the first adhesive 401, thereby forming the first adhesive layer 40 on the top surface 11 of the inflatable body 10. The second side 22 of the adhesive layer 20 is adhered to the padding area 111 of the top surface 11 of the inflatable body 10, thereby forming the second adhesive layer 50 between the adhesive layer 20 and the top surface 11 of the inflatable body 10.

[0109] It is worth mentioning that the adhesive layer 20 between the inflatable body 10 and the padding layer 30 has adhesive holding ability, which makes the adhesive distribution between the inflatable body 10 and the padding layer 30 more uniform. The adhesive layer 20 helps to retain more adhesive between the inflatable body 10 and the padding layer 30, making the inflatable body 10 and the padding layer 30 more firmly bonded and avoiding bulging and delamination.

[0110] In other words, the adhesive layer 20 contains a large amount of adhesive, and the adhesive is spread more evenly to form a good adhesive structure for the adhesive layer 20.

[0111] See appendix Figure 7 and Figure 8 This illustration shows an inflatable paddleboard according to a second preferred embodiment of the present invention. In this embodiment, the inflatable paddleboard includes an inflatable body 10, an adhesive layer 20, a padding layer 30, and a first adhesive coating layer 40. The adhesive layer 20 is disposed between the top surface 11 of the inflatable body 10 and the padding layer 30, and the first adhesive coating layer 40 is disposed between the adhesive layer 20 and the padding layer 30. In this embodiment, the second adhesive coating layer 50 between the adhesive layer 20 and the inflatable body 10 in the first preferred embodiment is omitted. The adhesive layer 20 is integrally disposed on the inflatable body 10 by means of hot pressing, ultrasonic welding, or other integrated methods.

[0112] In this embodiment, the adhesive layer 20 is integrally formed on the inflatable body 10 by hot pressing. During the hot pressing process, appropriate pressure can be applied to ensure that the adhesive layer 20 and the material on the top surface 11 of the inflatable body 10 are fully fused in the molten state. The pressure is generally adjusted according to factors such as material thickness, hardness, and heat sealing area.

[0113] When the adhesive layer 20 is made of a mesh containing thermoplastic components (such as polyester, nylon, polypropylene, or PU-coated fibers), the process generally works well, as these components can soften and fuse with PVC under heat and pressure.

[0114] After the adhesive layer 20 is bonded to the top surface 11 of the inflatable body 10, the first adhesive 401 can be applied between the adhesive layer 20 and the padding layer 30 to bond the adhesive layer 20 and the padding layer 30.

[0115] A stronger and more durable bond can be formed by directly integrating the adhesive layer 20 onto the top surface 11 of the inflatable body 10 through thermal lamination or ultrasonic welding. These methods melt the adhesive surface, then cool and solidify to form a fusion between the materials. This eliminates the need for an additional adhesive coating between the inflatable body 10 and the adhesive layer 20, thus ensuring a seamless and strong adhesion.

[0116] Using thermal lamination or ultrasonic welding ensures that the materials are fused at the molecular level, thus greatly improving the overall lifespan of the paddleboard. The adhesion between the inflatable body 10 and the adhesive layer 20 is unlikely to degrade over time, preventing problems such as delamination or peeling even after prolonged exposure to water, sunlight, and physical pressure.

[0117] The surfboard's durability and stability are enhanced, providing users with a more reliable and safer experience. Because the padding layer 30 is firmly bonded to the inflatable body 10 via the adhesive layer 20, users will benefit from a secure grip while paddling, reducing the risk of slipping and improving overall performance.

[0118] A first adhesive 401 is applied between the adhesive layer 20 and the padding layer 30. The manufacturer can customize the adhesive properties according to the specific materials used. This customization allows for more precise control of the adhesive strength and helps prevent premature wear of the anti-slip surface.

[0119] See appendix Figure 9 and Figure 10This illustration shows an inflatable paddleboard according to a third preferred embodiment of the present invention. In this embodiment, the inflatable paddleboard includes an inflatable body 10, an adhesive layer 20, a padding layer 30, and a second adhesive coating layer 50. The adhesive layer 20 is disposed between the top surface 11 of the inflatable body 10 and the padding layer 30, and the second adhesive coating layer 50 is disposed between the adhesive layer 20 and the inflatable body 10. In this embodiment, the first adhesive coating layer 40 between the adhesive layer 20 and the padding layer 30 in the first preferred embodiment is omitted, and the adhesive layer 20 is integrally disposed on the padding layer 30 by means of hot pressing, ultrasonic welding, or other integrated methods.

[0120] After the adhesive layer 20 is bonded to the padding layer 30, a second adhesive 501 can be applied between the adhesive layer 20 and the top surface 11 of the inflatable body 10 to bond the adhesive layer 20 to the top surface 11 of the inflatable body 10.

[0121] See appendix Figures 11 to 12 The illustration shows an inflatable kayak according to a fourth preferred embodiment of the invention. The inflatable kayak includes an inflatable body 10, which includes a cabin 12, an adhesive layer 20, and a padding layer 30 disposed within the cabin 12, wherein the adhesive layer 20 is used to securely connect the cabin 12 and the padding layer 30 together.

[0122] More specifically, in this embodiment, the pad 30 serves as a seat cushion for the user to sit on, and the inflatable kayak also includes a first adhesive coating 40 and a second adhesive coating 50. The first adhesive coating 40 is applied between the adhesive layer 20 and the pad 30 to firmly bond the adhesive layer 20 and the pad 30 together.

[0123] The cockpit 12 has a cockpit cavity 121 and a bottom surface 122 located at the bottom of the cockpit cavity 121. The second adhesive coating 50 is disposed between the adhesive layer 20 and the bottom surface 122 at the bottom of the cockpit cavity 121 so that the adhesive layer 20 is firmly adhered to the inflatable body 10.

[0124] Alternatively, the adhesive layer 20 can be integrated with either the padding layer 30 or the cabin section 12 of the inflatable kayak using integration methods such as hot pressing or ultrasonic welding.

[0125] See Figures 13 to 14 The illustration shows an inflatable dog ramp according to a fifth preferred embodiment of the invention. This inflatable dog ramp or ramp is used to help dogs safely enter and exit the water after swimming or playing in the water, and is typically attached to the side of a boat, dock, or inflatable platform. In this embodiment, the inflatable dog ramp includes an inflatable body 10, an adhesive layer 20, and a padding layer 30 disposed on the inflatable body 10, wherein the adhesive layer 20 is used to securely attach the padding layer 30 to the inflatable body 10.

[0126] More specifically, in this embodiment, the padding layer 30 serves as a mat for the dog to sit or stand on, and the inflatable dog ladder also includes a first adhesive coating layer 40 and a second adhesive coating layer 50. The first adhesive coating layer 40 is applied between the adhesive layer 20 and the padding layer 30 to firmly bond the adhesive layer 20 and the padding layer 30 together. The second adhesive coating layer 50 is applied between the adhesive layer 20 and the top surface 11 of the inflatable body 10 to firmly bond the adhesive layer 20 and the inflatable body 10 together.

[0127] Alternatively, the adhesive layer 20 can also be integrated with one of the padding layer 30 of the inflatable dog climbing ladder and the top surface 11 of the inflatable body 10 through an integrated method such as hot pressing or ultrasonic welding.

[0128] See Figures 15 to 16 The invention illustrates an inflatable fishing platform according to a sixth preferred embodiment of the invention, designed for anglers to fish in the middle of a lake or river, comprising an inflatable body 10, one or more adhesive layers 20, and one or more pads 30 disposed on the inflatable body 10, wherein each adhesive layer 20 is used to securely attach the corresponding pad 30 to the inflatable body 10.

[0129] More specifically, in this embodiment, the pad 30 is a pad for the angler to stand on. The inflatable fishing platform may include two pads 30. Accordingly, two adhesive layers 20 are used to fix the two pads 30 to the inflatable body 10.

[0130] The inflatable fishing platform also includes one or more first adhesive coatings 40 and one or more second adhesive coatings 50.
