The pool or whirlpool includes an inflatable air chamber 60 formed between the upper wall 10, the lower wall 20, the inner wall 30 and the outer wall 40. The air chamber 60 includes one or more suitable ventilation holes (not shown) to inflate and deflate the air chamber 60. In some embodiments, the air chamber 60 may be inflated at a relatively high pressure, greater than about 5.52 kPa (0.8 psi). For example, the air chamber 60 may be inflated at a pressure of approximately 6.21 kPa (0.9 psi), 6.89 kPa (1.0 psi), 7.58 kPa (1.1 psi), 8 , 27 kPa (1.2 psi), 8.96 kPa (1.3 psi), 9.65 kPa (1.4 psi), 10.34 kPa (1.5 psi), 11.03 kPa (1, 6 psi), or more. Such pressures may be approximately 1.5 or 2 times greater than the pressures used to inflate traditional inflatable products.

The hydromassage pool also includes a water cavity 112 formed by the bottom wall 20 and the inner wall 30.

Within the air chamber 60, the pool also includes a plurality of structures or tension, interval or reinforcement elements 50 that maintain the shape of the pool when the air chamber 60 is pressurized. Tension structures 50 can improve strength of the pool, allowing the air chamber 60 to withstand relatively high internal pressures, as set forth above, while providing comfort to a user who sits on the edge or inside the pool or whirlpool.

As shown in Figures 1 and 2, the tension structures 50 are arranged vertically and radially in the air chamber 60 in an annular die pattern. As shown in Figure 3, each tension structure 50 can be coupled to the internal wall 30 and the external wall 40, as further discussed below with reference to Figures 7 and 8. In addition, each tension structure 50 it can be separated from the upper wall 10 and the lower wall 20 to define an upper recess 70 with respect to the upper wall 10 and a lower recess 80 with respect to the lower wall 20.

Referring below to Figures 4 to 6, each tension structure 50 may include a porous sheet or layer 52 and one or more sheets or tie layers 54 joined (eg, laminated) to the porous layer 52. In the embodiment illustrated in Figure 5, the porous layer 52 is sandwiched between two tie layers 54, the tie layers 54 being joined to the upper surface and the lower surface of the porous layer 52. In the illustrated embodiment of Figure 6, the Porous layer 52 is attached to an individual bonding layer 54, the individual bonding layer 54 being attached to the upper surface 160 or the lower surface 162 of the porous layer 52.

With the exception of the upper recess 70 and the lower recess 80 in the tension structure 50, the tension structure 50 can generally be rectangular in shape, as shown in Figure 4. In the present embodiment, the porous layer 52 includes a generally rectangular outer perimeter 150 formed by the edges 152a-d, and the joining layer 54 includes a generally rectangular outer perimeter 154 formed by the edges 156a-d. The bonding layer 54 may extend throughout the porous layer 52, as shown in Figure 5, such that the outer perimeter of the bonding layer generally overlaps with the outer perimeter of the porous layer. It is also within the scope of the present description that the bonding layer may extend over a part of the porous layer.

The porous layer 52 can be formed from a plurality of linkages or frame members 134 that define a plurality of holes or pores 136 with each other, as shown in Figure 4. When the air chamber 60 is pressurized, the members of frame 134 can be placed in tension to help maintain the shape of a whirlpool 1. Adjacent frame members 134 can be separated at regular intervals to provide tension structure 50 with substantially constant tensile strength.

Each pore 136 of the porous layer 52 may be confined or completely surrounded by frame members 134 at an intersection in a 360 ° range. A plurality of pores 136 may be located completely within the outer perimeter 154 of the tie layer 54 to facilitate bonding to the tie layer 54, as discussed further below. It is also within the scope of the present description that other pores 136 may be located outside the outer perimeter 154 of the joint layer 54. The size and shape of each pore 136 may vary depending on the thickness and orientation of the frame members. 134 surrounding. For example, the porous layer 52 may also include a plurality of open spaces 158 that are partially surrounded by frame members 134 and partially exposed along the outer perimeter 150.

In the illustrated embodiment of Figure 4, the frame members 134 are arranged in a grid pattern, which includes a first set of separate and parallel frame members 138 and a second set of separate and parallel frame members 139. In this grid pattern, the first set of frame members 138 is transverse to the second set of frame members 139 so that the first set of frame members 138 intersects with the second set of frame members

139. In Figure 4, the grid pattern is rotated approximately 45 ° with respect to a horizontal axis to resemble a grid, so that the first set of frame members 138 is inclined upwardly with respect to the horizontal axis (by for example, approximately + 45 ° with respect to the horizontal axis), and the second set of frame members 139 is inclined downwards with respect to the horizontal axis (for example, approximately -45 ° with respect to the horizontal axis) and substantially perpendicular to the first set of frame members 138. Between the frame members 134 adjacent, diamond-shaped pores 136 are uniformly spaced in FIG. 4. Adjacent pores 136 may also be inclined up and down with respect to the horizontal axis. .

According to an exemplary embodiment of the present description, the porous, screen or pattern layer 52 may be made of mesh, fabric or a screen having interwoven ropes, fibers or wires as individual frame members 134. Some embodiments use polyester, nylon or cotton fibers. As shown in Figure 4, each frame member 134 may include a first terminal end 170 located at one edge (for example, edge 152a) of the porous layer 130 and a second terminal end 172 located at an opposite edge ( for example, the edge 152c) of the porous layer 52.

As discussed above, each tension structure 50 can be coupled to the inner wall 30 and the outer wall 40 using suitable coupling techniques, such as, for example, high frequency coupling, hot coupling (eg, fusion, welding ) or adhesion (for example, gluing). In the illustrated embodiment of Figure 7, the tension structure 50 is directly coupled to the inner wall 30 and to the external wall 40 along a seam 142. In the illustrated embodiment of Figure 8, the tension structure 50 is indirectly coupled to the internal wall 30 and the external wall 40 using intermediate connection layers 140. More specifically, the tension structure 50 is coupled to the intermediate connection layers 140 by means of a first seam 144, and the intermediate connection layers 140 are coupled to the inner wall 30 and the outer wall 40 by means of a second seam 146. As shown in Figures 7 and 8, the seams 142, 144, 146 may be located along opposite edges (by for example, the edges 152a, 156a and the edges 152c, 156c) of the tension structure 50. Returning to Figure 4, the seams 142, 144, 146 are shown extending in a vertical direction along the b right side orifices 152a, 156a, of the tension structure 50 to join the tension structure 50 to the adjacent inner wall 30 and along the edges of the left side 152c, 156c of the tension structure 50 to join the tension structure tension 50 to the adjacent outer wall 40, for example.

According to an exemplary embodiment of the present description, the frame members 134 are oriented transversely (ie, not parallel) to the seams 142, 144, 146. In Figure 4, the frame members 138 are inclined side by side. another in the vertical direction. In the present embodiment, such as vertical seams 142, 144, 146 and any line parallel to vertical seams 142, 144, 146 pass through tension structure 50, the vertical line will intersect at least with a pore 136 or space open 158 between the frame members 134. In other words, there is no vertical line that passes completely through the tension structure 50 along a frame member 134 without intersecting at least one pore 136 or open space 158 adjacent to the frame member 134. In Figure 4, the frame members 138 are also oriented transversely to any horizontal line that is perpendicular to the seams 142, 144,

146. As set forth above, the frame members 138 are inclined up and down in the horizontal direction. In the present embodiment, as any horizontal line perpendicular to the vertical seams 142, 144, 146 passes through the tension structure 50, the horizontal line will intersect at least with a pore 136 or open space 158 between the frame members 134 In other words, there is no horizontal line that passes completely through the tension structure 50 along a frame member 134 without intersecting at least one pore 136 or open space 158 adjacent to the frame member 134.

To facilitate secure connections between tension structure 50, internal wall 30, external wall 40 and optional intermediate connection layers 140, the materials used to construct these adjacent layers may be the same or different and compatible. For example, if the inner wall 30, the outer wall 40 and the optional intermediate connection layers 140 are made of PVC, TPR, EVA or TPU, at least a part of the corresponding tension structure 120 may also be made of PVC, TPR, EVA or TPU. In embodiments in which adjacent layers are fused together using, for example, high frequency radiation, compatible materials may have the same or similar melting points to ensure that the materials melt, mix together and form secure connections. According to an exemplary embodiment of the present description, at least the joint layer 54 of the tension structure 50 may be made of a compatible material. In contrast, the porous layer 52 of the tension structure 50 may be made of a different material, potentially incompatible (for example, with a higher melting point) and potentially more resistant, since the pores 136 of the porous layer 130 can admitting the joining of adjacent compatible materials (for example, one or more tie layers 54, the inner wall 30 of the whirlpool, the outer wall 40 of the whirlpool and / or the optional intermediate connecting layers 140) a through the pores 136 in the porous layer 130. For example, the joint layer 54 of the tension structure 50 may be made of a compatible material such as PVC, TPR, EVA or TPU, while the porous layer 52 of the Tension structure 50 may be made of a fabric or screen.
