Description

Technical Field

[0001] This utility model relates to the field of inflatable trampoline technology, and in particular to an inflatable trampoline. Background Technology

[0002] With the rapid development of society and economy, inflatable trampolines are widely used in children's amusement facilities. They can be placed on the ground or float on water, allowing people to jump freely while relaxing, entertaining, and exercising. Whether in squares, amusement parks, beaches, lakes, or swimming pools, inflatable trampolines are the most attractive attractions.

[0003] In existing technologies, inflatable trampolines typically involve fusing multiple PVC sheets together to form an inflatable frame. However, these products suffer from poor abrasion resistance and tear resistance, resulting in a short lifespan and poor elasticity. Other products incorporate a fabric layer within the PVC sheets, creating a mesh-like structure. Multiple pieces of this mesh are then glued together to form a roughly circular inflatable frame, with an elastic trampoline surface positioned in the center. The inflatable frame can be placed on the ground or float on water. However, the manufacturing process for these products is complex, requiring the gluing of numerous sheets, which can lead to poor airtightness. Furthermore, the gluing process requires skilled workers, resulting in low production efficiency and high costs. Additionally, the mesh layer's poor welding performance prevents direct overlapping and welding of the mesh layers in existing products.

[0004] Therefore, this utility model provides an inflatable trampoline that can effectively solve the above problems. It has a simple structure, good sealing effect, simple manufacturing process, strong wear resistance and tear resistance, is portable and easy to use, has high production efficiency and low production cost.

[0013] As an improvement of this utility model, the second sheet is provided with a third welding area at the edge away from the first sheet, and the third welding areas of two adjacent second sheets are welded together.

[0014] As an improvement of this utility model, the inner surfaces of the third welding zone of two adjacent second sheets are attached to each other and welded together.

[0015] As an improvement of this utility model, there are four first sheets and eight second sheets. The first and second ends of each first sheet are adjacent to each other, and the first and second sheets are adjacent to each other. The first sheets and the second sheets form a circular inflatable frame.

[0016] As an improvement of this utility model, the first sheet is provided with an air valve assembly, which at least partially penetrates the side wall of the first sheet. The air valve assembly is opened to allow gas to flow into or out of the inflation cavity.

[0017] As an improvement of this utility model, the air valve assembly includes a valve body and a valve cover. The valve body is provided with an airflow channel. The valve cover is detachably connected to the valve body. When the valve cover is connected to the valve body, the valve cover closes the airflow channel.

[0018] As an improvement of this utility model, the air valve assembly further includes a connecting strap, one end of which is connected to the valve body and the other end of which is connected to the valve cover.

[0019] As an improvement of this utility model, it also includes a handle assembly, which is connected to the outer surface of the first sheet; the handle assembly includes a handle and a handle connector, the handle connector is connected to the outer surface of the first sheet, and the handle is connected to the outer surface of the handle connector.

[0020] As an improvement to this utility model, the elastic component includes an elastic rope and an elastic mesh fabric. The elastic rope is connected to the connecting sheet through the first connector, and the elastic mesh fabric is connected to the elastic rope through a plurality of second connectors.

[0021] As an improvement of this utility model, the first connector is a flat cloth strip, with the two ends of the first connector stacked one on top of the other and connected to the lower surface of the connecting sheet by a first sewing thread, and the first connector is sleeved on the elastic rope.

[0025] The beneficial effects of this utility model are as follows: With the above-described structure, when in use, gas is injected into the inflation cavity, causing the inflatable frame to inflate and harden, providing stable support. When the user sits, lies, walks, or jumps on the elastic component, the elasticity of the component effectively propels the user to jump or supports them. The force on the elastic component is evenly distributed to the inflatable frame through the connecting sheets, providing stable support. Furthermore, because the inflatable frame has an inflation cavity and low density, it can float on water under buoyancy, increasing the product's adaptability and appeal. Specifically, both the first and second sheets are P... The VC material sheet has a fabric layer inside the first sheet. The fabric layer provides support, prevents the first sheet from deforming under stress, maintains the stability of the product, and also enhances the product's wear resistance, tear resistance, and weather resistance, effectively extending the product's service life. However, because the first sheet has a fabric layer inside, its weldability is poor compared to the second sheet made of pure PVC material. Directly welding two first sheets can easily lead to breakage at the joint. Connecting two adjacent first sheets through the second sheet can improve the stability of the connection and ensure the airtightness and structural stability of the product.

[0047] Reference Figures 1 to 13 An inflatable trampoline, comprising:

[0048] An inflatable frame 100 includes a plurality of first sheets 110 and a plurality of second sheets 120. The first sheets 110 have a fabric layer 112 inside. Two second sheets 120 are respectively fused to two edges of the first sheets 110. Two adjacent second sheets 120 are fused to each other. The first sheets 110 and the second sheets 120 form an inflatable frame 100. The inflatable frame 100 has an inflation cavity 101 inside.

[0049] A connecting sheet 200 is provided, the edge of which is fused to the upper surface of the inflatable frame 100, and an opening 201 is provided in the middle of the connecting sheet 200;

[0050] An elastic component 300 is located within the opening 201 and is connected to the connecting sheet 200 via a plurality of first connectors 210.

[0051] With the above-described structure, during use, gas is injected into the inflation chamber 101, causing the inflatable frame 100 to inflate and harden, providing stable support. When a user sits, lies down, walks, or jumps on the elastic component 300, the elasticity of the elastic component 300 effectively propels the user to jump or supports the user. The force on the elastic component 300 is evenly distributed to the inflatable frame 100 through the connecting sheet 200, providing stable support. Furthermore, because the inflatable frame 100 has an inflation chamber 101, its low density allows it to float on water under buoyancy, increasing the product's adaptability and appeal. Both the first sheet 110 and the second sheet 120 are made of PVC. The sheet material has a fabric layer 112 inside the first sheet 110. The fabric layer 112 can provide support, prevent the first sheet 110 from deforming under stress, maintain the stability of the product, and also enhance the wear resistance, tear resistance and weather resistance of the product, effectively extending the service life of the product. However, because the first sheet 110 has a fabric layer 112 inside, compared with the second sheet 120 made of pure PVC material, the first sheet 110 has poor weldability. Directly welding two first sheets 110 can easily cause the joint to break. However, connecting two adjacent first sheets 110 through the second sheet 120 can improve the stability of the connection and ensure the airtightness and structural stability of the product.

[0052] In this embodiment, a first welding area 111 is provided on both edges of the first sheet 110, and a second welding area 121 is provided on the second sheet 120 near the edge of the first sheet 110. The first welding area 111 and the second welding area 121 are stacked vertically and welded together. By setting the structure as described above, stacking the first welding area 111 and the second welding area 121 vertically increases the contact area between the two and effectively prevents the first sheet 110 and the second sheet 120 from moving or deforming during the welding process, ensuring the stability of the connection. Then, a high-frequency plastic welding machine is used to weld the first welding area 111 and the second welding area 121 together, ensuring the stability of the product and effectively reducing the occurrence of breakage or air leakage at the connection between the first sheet 110 and the second sheet 120.

[0053] In this embodiment, the distance between the fabric layer 112 and the upper surface of the first sheet 110 is less than the distance between the fabric layer 112 and the lower surface of the first sheet 110. The lower surface of the first welding area 111 is bonded and welded to the upper surface of the second welding area 121. With this structure, since the distance between the fabric layer 112 and the upper surface of the first sheet 110 is less than the distance between the fabric layer 112 and the lower surface of the first sheet 110, the thickness of the PVC layer at the lower surface of the first sheet 110 is greater. Bonding and welding the lower surface of the first welding area 111 to the upper surface of the second welding area 121 further ensures the stability of the connection between the first sheet 110 and the second sheet 120, guaranteeing the airtightness and service life of the product. Simultaneously, the smaller distance between the fabric layer 112 and the upper surface of the first sheet 110 means that the fabric layer 112 is located near the outer surface of the first sheet 110, further improving the product's abrasion resistance, tear resistance, and weather resistance.

[0054] In this embodiment, the edge of the second sheet 120 away from the first sheet 110 is provided with a third welding area 122, and the third welding areas 122 of two adjacent second sheets 120 are welded together. With the above structure, when producing the product, the third welding areas 122 of two adjacent second sheets 120 are aligned and extended outwards, and then a high-frequency plastic welding machine is used to weld the two third welding areas 122, realizing the connection between two adjacent second sheets 120. Since the second sheet 120 is made of pure PVC material, the connection between two adjacent second sheets 120 is stable, ensuring the airtightness of the product; and aligning the third welding areas 122 of two adjacent second sheets 120 and extending them outwards makes it easier for the high-frequency plastic welding machine to act on the third welding area 122, reducing production difficulty and improving production efficiency.

[0055] In this embodiment, the inner surfaces of the third welding areas 122 of two adjacent second sheets 120 are bonded and welded together. With the above structure, during product manufacturing, the inner surfaces of the third welding areas 122 of the two second sheets 120 are bonded together, at which point the third welding areas 122 protrude outwards. Then, a high-frequency plastic welding machine is used to weld the two third welding areas 122 together, which is simple to operate and has high production efficiency.

[0056] In this embodiment, there are four first sheets 110 and eight second sheets 120. The first and second ends of each first sheet 110 are adjacent, and the first and second ends of each second sheet 120 are adjacent. The first sheets 110 and the second sheets 120 form a circular inflatable frame 100. With this structure, the circular inflatable frame 100 experiences more balanced stress, resulting in a longer product lifespan. Furthermore, the recessed area in the center of the inflatable frame 100 provides deformation space for the elastic component 300, making it easier for users to jump while using the product, thus improving its performance.

[0057] In this embodiment, the first sheet 110 is provided with an air valve assembly 400, which at least partially penetrates the side wall of the first sheet 110. The air valve assembly 400 is open to allow gas to flow into or out of the inflation cavity 101. With the above structure, in use, the air valve assembly 400 is opened, and an air pump or other device is used to inflate the product, filling the inflation cavity 101 with gas to form a stable inflation frame 100 structure. Then, the air valve assembly 400 is closed to ensure the airtightness of the product. When it is necessary to store the product, the air valve assembly 400 can be opened to release the gas in the inflation cavity 101, reducing the product volume and making it convenient for users to store and transport the product.

[0058] In this embodiment, the valve assembly 400 includes a valve body 410 and a valve cover 420. The valve body 410 has an airflow channel 411. The valve cover 420 is detachably connected to the valve body 410. When the valve cover 420 is connected to the valve body 410, the valve cover 420 covers the airflow channel 411. With the above structure, in use, the valve cover 420 is opened, and an air pump or other device is used to align with the airflow channel 411 to inflate the product, filling the inflation chamber 101 with gas to form a stable inflation frame 100 structure. Then, the valve cover 420 is used to cover the airflow channel 411 to ensure the airtightness of the product. When it is necessary to store the product, the airflow channel 411 can be opened to discharge the gas in the inflation chamber 101 through the airflow channel 411, reducing the product volume and facilitating the user's storage and transportation of the product. Preferably, a check device, such as a one-way valve or a diaphragm, is also provided in the airflow channel 411.

[0059] In this embodiment, the valve assembly 400 further includes a connecting strap 430, one end of which is connected to the valve body 410, and the other end of which is connected to the valve cover 420. Through this structural arrangement, the connecting strap 430 can connect the valve cover 420 to the valve body 410, preventing the valve cover 420 from being lost after opening and improving the user experience.

[0060] In this embodiment, a handle assembly 500 is also included, which is connected to the outer surface of the first sheet 110. The handle assembly 500 includes a handle 510 and a handle connector 520. The handle connector 520 is connected to the outer surface of the first sheet 110, and the handle 510 is connected to the outer surface of the handle connector 520. By configuring the above structure, the handle 510 can be effectively fixed by connecting the handle connector 520 to the outer surface of the first sheet 110 and then connecting the handle assembly 500 to the outer surface of the handle connector 520. Furthermore, the contact area between the handle connector 520 and the outer surface of the first sheet 110 is relatively large, resulting in strong product stability and a stable structure.

[0061] In this embodiment, the elastic component 300 includes an elastic rope 310 and an elastic mesh fabric 320. The elastic rope 310 is connected to the connecting sheet 200 via a first connector 210, and the elastic mesh fabric 320 is connected to the elastic rope 310 via several second connectors 330. With this structure, during product manufacturing, the elastic rope 310 is connected to the elastic mesh fabric 320 via the second connectors 330, and then connected to the connecting sheet 200 via the first connectors 210. When a user moves on the elastic mesh fabric 320, the elastic rope 310 deforms and then returns to its original position, providing elastic force that effectively drives the user to jump.

[0062] In this embodiment, the first connector 210 is a flat fabric strip. The two ends of the first connector 210 are stacked vertically and connected to the lower surface of the connecting sheet 200 via a first sewing thread. The first connector 210 is sleeved on the elastic rope 310. With this structure, the two ends of the first connector 210 can be stably connected to the lower surface of the connecting sheet 200 by sewing, forming a fabric strip loop. The elastic rope 310 is then passed through this loop, facilitating connection. Furthermore, the flat fabric strip and the elastic rope 310 have a large contact area, allowing force to be applied evenly to the elastic rope 310, resulting in a stable product structure and a long lifespan.

[0063] In this embodiment, the elastic mesh fabric 320 has two connecting portions 321 along its edge. The second connecting member 330 is a flat fabric strip, with its two ends stacked vertically. The two connecting portions 321 are clamped between the two ends of the second connecting member 330 and connected to the two ends of the second connecting member 330 via a second sewing thread. The second connecting member 330 is fitted onto the elastic rope 310. With this structure, the two ends of the second connecting member 330 can be stably connected to the connecting portions 321 along the edge of the elastic mesh fabric 320 by sewing, forming a fabric loop. The elastic rope 310 is then passed through this loop, facilitating connection. Furthermore, the flat fabric strip and the elastic rope 310 have a large contact area, allowing force to be applied evenly to the elastic rope 310, resulting in a stable product structure and long lifespan. The two connecting portions 321 clamping the upper and lower sides of the ends of the second connecting member 330 further enhance the stability of the product connection.

[0064] In this embodiment, both the first connector 210 and the second connector 330 form a fabric loop, and the first connector 210 and the second connector 330 are alternately sleeved on the elastic rope 310. Through the above structural arrangement, the alternating sleeved arrangement of the first connector 210 and the second connector 330 on the elastic rope 310 ensures balanced force distribution on the elastic rope 310 in the diametrical direction, resulting in a stable product structure.

[0065] In this embodiment, the elastic mesh fabric 320 is circular, and the second connectors 330 are equally spaced along the circumference at the edge of the elastic mesh fabric 320. With this structure, the second connectors 330 are equally spaced along the circumference, allowing the force on the elastic mesh fabric 320 to be evenly distributed onto the elastic rope 310 through the second connectors 330, resulting in balanced force distribution on the product.
