Description

Technical Field

[0001] This utility model relates to the field of outdoor swimming pool technology, specifically an airless foldable swimming pool suitable for various occasions such as homes, parks, and playgrounds, providing users with a convenient, stable, and safe swimming or water play environment. Background Technology

[0002] Existing outdoor swimming pool solutions commonly include manually dug pools, inflatable pools, and traditional non-inflatable pools. Manually dug pools require significant manpower, resources, and time, and their location is fixed, offering little flexibility. While inflatable pools offer convenience, their use of PVC mesh fabric results in poor stability during use. When people move within the pool, creating waves that impact the pool walls, it causes overall swaying, making it impossible to place items or provide seating, thus limiting their practicality. Traditional non-inflatable pools are typically placed directly on the ground, lacking effective external support structures, resulting in similarly poor stability and failing to meet users' needs for safety and stability.

[0003] To address the aforementioned issues, this invention presents a non-inflatable, foldable swimming pool, aiming to overcome the shortcomings of existing swimming pools in terms of stability and portability, and to provide a swimming pool product that is convenient to use, highly stable, and easy to store. Utility Model Content

[0004] The present invention aims to address the shortcomings of existing swimming pools in terms of stability and portability by providing an airless, foldable swimming pool that is convenient to use, highly stable, and easy to store.

[0005] This utility model is implemented as follows: it provides a non-inflatable foldable swimming pool, including a pool body made of flexible waterproof material. The pool body is surrounded by a fence composed of several waterproof side layers. Each waterproof side layer contains a rigid support plate to provide necessary strength and support for the fence. Several foldable diagonal supports are provided outside the fence of the pool body. Each foldable diagonal support includes two waterproof support layers. The sides of the two waterproof support layers are connected by a first flexible connector. Each waterproof support layer contains a side support plate. Each foldable diagonal support is correspondingly set outside two adjacent waterproof side layers at a designated position. The upper edges of the waterproof support layers on both sides are respectively connected to the upper outer walls of the two waterproof side layers by a second flexible connector. The outer edges of the waterproof support layers on both sides are respectively connected to the upper outer walls of the two waterproof side layers by a third flexible connector.

[0006] Furthermore, the multiple continuous waterproof side layers are formed by hot-pressing a first PVC waterproof fabric and a second PVC waterproof fabric. Each of the rigid support plates is pre-placed within the partition layer composed of the first and second PVC waterproof fabrics before hot-pressing to ensure structural stability.

[0007] Furthermore, each of the waterproof support interlayers is formed by hot pressing together a third PVC waterproof fabric and a fourth PVC waterproof fabric, and each of the side support plates is pre-placed in a partition layer composed of the third PVC waterproof fabric and the fourth PVC waterproof fabric before hot pressing; the first flexible connector, the second flexible connector, and the third flexible connector are all formed by extending outward from the third PVC waterproof fabric and / or the fourth PVC waterproof fabric.

[0008] Furthermore, a V-shaped notch is formed on the upper side between the two waterproof support layers of each of the foldable inclined supports. The first flexible connector is connected to the lower side between the two sides, and the upper ends of the two waterproof support layers are inclined outwards respectively. Then, they are connected to the upper outer wall of the waterproof side layer through the second flexible connector. This design helps to better distribute pressure during support and improve the support effect.

[0009] Furthermore, the third flexible connector is narrower at the top and wider at the bottom, which ensures connection strength while facilitating folding operations, allowing the foldable diagonal support to fit more closely to the fence and reduce storage space.

[0010] Furthermore, the foldable inclined support has a first flexible connector as the first folding part, a second flexible connector and a third flexible connector as the second folding part of the foldable inclined support and the fence, and the connection between the waterproof side interlayers of the fence as the third folding part.

[0011] Compared with existing technologies, this utility model achieves the foldable function of the diagonal support through the ingenious connection of the foldable diagonal support and the first, second, and third flexible connectors, while ensuring stable support performance in use. By folding the waterproof side layers of the enclosure together, and by folding and storing the foldable diagonal support, the overall storage and unfolding of the pool becomes simpler and faster, greatly improving the product's usability. The V-shaped notch between the waterproof support layers on both sides of the foldable diagonal support and the outward tilt at the top optimize the support structure, making the pressure distribution more reasonable and effectively improving the overall stability of the pool.

[0019] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Please refer to Figures 1-7As shown, this utility model discloses a non-inflatable foldable swimming pool, comprising a pool body 1 made of flexible waterproof material. The pool body 1 has a perimeter fencing 10 continuously formed by several waterproof side layers 11. Each waterproof side layer 11 contains a rigid support plate 12, which provides rigid support for the fencing 10, preventing excessive deformation under water pressure and ensuring the basic shape and structural stability of the pool. The pool body 1, made of flexible waterproof material, is relatively soft and difficult to maintain a stable shape; the addition of the rigid support plate 12 compensates for this deficiency. Several foldable inclined supports 3 are provided outside the fencing of the pool body 1. Each foldable inclined support 3 includes two waterproof support layers 31, whose sides are joined together by a first flexible connector 32. Each waterproof support layer 31 contains a side support plate 35, which provides internal support for the foldable inclined support 3, enhancing its foldability. The strength of support 3 enables it to better withstand lateral forces. The foldable diagonal support 3 needs to withstand lateral forces such as water flow impact generated by personnel activities during pool use, and the side support plate 35 ensures its structural strength. Each foldable diagonal support 3 is correspondingly set outside two adjacent waterproof side interlayers 11 at a designated position. The upper edge of the waterproof support interlayer 31 on both sides is connected to the upper outer wall of the two waterproof side interlayers 11 through the second flexible connector 33, and the outer edge of the waterproof support interlayer 31 on both sides is connected to the upper outer wall of the two waterproof side interlayers 11 through the third flexible connector 34. The second flexible connector 33 and the third flexible connector 34 realize a stable connection between the foldable diagonal support 3 and the fence 10, so that the foldable diagonal support 3 can effectively transfer the force to the fence 10 and jointly withstand the lateral forces. During pool use, the foldable diagonal support 3 and the fence 10 need to work together to resist lateral forces, and a stable connection is the basis for ensuring this collaborative work.

[0021] The multiple continuous waterproof side interlayers 11 are formed by hot pressing together a first PVC waterproof fabric 110 and a second PVC waterproof fabric 111. Each rigid support plate 12 is pre-placed within the interlayer formed by the first PVC waterproof fabric 110 and the second PVC waterproof fabric 111 before hot pressing. The hot pressing process ensures the sealing and structural integrity of the waterproof side interlayers 11. Pre-placing the rigid support plates 12 before hot pressing ensures that the rigid support plates 12 are firmly encapsulated within the waterproof side interlayers 11. Technical explanation: Hot pressing allows the first PVC waterproof fabric 110 and the second PVC waterproof fabric 111 to be tightly bonded, preventing water from seeping into the interlayer and affecting the performance and service life of the rigid support plates 12.

[0022] Each of the aforementioned waterproof support interlayers 31 is formed by hot pressing together a third PVC waterproof fabric 311 and a fourth PVC waterproof fabric 312. Each of the aforementioned side support plates 35 is pre-placed within the partition formed by the third PVC waterproof fabric 311 and the fourth PVC waterproof fabric 312 before hot pressing. Similarly, hot pressing ensures the sealing and structural integrity of the waterproof support interlayer 31, and pre-placing the side support plates 35 before hot pressing ensures that the side support plates 35 are securely sealed. Similar to the manufacturing principle of the waterproof side interlayer 11, this ensures the effective protection of the side support plates 35 by the waterproof support interlayer 31. The first flexible connector 32, the second flexible connector 33, and the third flexible connector 34 are all extended outward from the third PVC waterproof fabric 311 and / or the fourth PVC waterproof fabric 312. The flexible connectors extended from the same material are more tightly and firmly connected to the waterproof support interlayer 31, and have good flexibility, which facilitates the folding and unfolding of the foldable inclined support 3. The connectors of the same material are more compatible with the waterproof support interlayer 31 in terms of physical and chemical properties, which can better integrate and improve the reliability and durability of the connection.

[0023] A V-shaped notch 310 is formed on the upper side between the two waterproof support layers 31 of each of the foldable inclined supports 3. The design of the V-shaped notch 310 can reduce the weight of the foldable inclined support 3 while ensuring its strength, making it easier to handle and fold. Technical explanation: Under the premise of meeting the structural strength requirements, reducing the amount of material used can reduce the weight. At the same time, the V-shaped structure has a certain mechanical stability. The first flexible connector 32 is connected to the lower side between the two sides, and the upper ends of the two waterproof support layers 31 are respectively inclined outward. Then, it is connected to the upper outer wall of the waterproof side layer 11 through the second flexible connector 33. This connection method makes the connection between the foldable inclined support 3 and the fence 10 more stable and can better transmit lateral force. At the same time, the design of the upper end being inclined outward increases the stability of the support. The upper end being inclined outward can expand the support area, improve the support effect on the fence 10, and enhance the stability of the overall structure.

[0024] The third flexible connector 34 is narrow at the top and wide at the bottom. This shape allows the third flexible connector 34 to better distribute stress and enhance the strength of the connection when connected to the waterproof side interlayer 11, while also facilitating folding operations. Under stress, the narrow-at-the-top and wide-at-the-bottom structure can transmit the force more evenly to the connection part, reduce local stress concentration, improve the reliability of the connection, and make the folding operation easier.

[0025] The foldable inclined support 3 has a first flexible connector 32 as the first folding part, and the second flexible connector 33 and the third flexible connector 34 constitute the second folding part between the foldable inclined support 3 and the fence 10. The connecting parts 13 between the waterproof side layers 11 of the fence 10 serve as the third folding part. The multiple folding parts allow the pool to be folded in multiple stages, greatly reducing the storage volume and facilitating transportation and storage. By folding different parts, the pool can be gradually reduced from its usable state to a compact shape, making full use of space and facilitating user operation.

[0026] Usage: Unfold the foldable diagonal support 3, allowing the two side support plates 35 to be joined together via the first flexible connector 32. The upper and outer edges of the two side support plates 35 are then securely connected to the upper outer wall of the adjacent waterproof side interlayer 11 via the second flexible connector 33 and the third flexible connector 34, respectively. At this point, the foldable diagonal support 3 and the fence 10 form a stable support structure, providing reliable lateral support for the pool and ensuring that the pool can withstand the water flow impact generated by personnel activities during use, maintaining overall stability. The stable support structure guarantees the safety and reliability of the pool during use, providing users with a good user experience. The water flow impact generated by personnel activities will exert a large lateral force on the pool sidewalls; the stable support structure can effectively resist these forces, preventing pool deformation or damage.

[0027] Folded State: When storing, first loosen the connection between the foldable diagonal support 3 and the fence 10. Using the first flexible connector 32 as the folding axis, fold the two side support plates 35 inward, so that the foldable diagonal support 3 is tightly attached to the fence 10. Then, fold the fence 10 through the folding parts 13 between the waterproof side layers 11 of the fence 10, finally folding the entire pool into a compact shape that is easy to transport and store, effectively saving storage space. The compact folded shape makes it convenient for users to transport and store the pool, improving the practicality and convenience of the product; reducing the storage volume reduces the requirements for storage space, allowing the pool to be placed more conveniently when not in use, saving users' operating costs.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
