Abstract

The present invention provides a above ground pool, comprising a flexible pool body. The flexible pool body comprises: a polygonal bottom sheet that comprises a plurality of edge portions; and a plurality of side sheets, each side sheet comprising a pool sidewall portion and a pool bottom portion, and each of the pool sidewall portions and each of the pool bottom portions being in the shape of an isosceles trapezoid. Each of pool sidewall portion comprises a first upper-base portion, a first lower-base portion and a first middle portion defined between the first upper-base portion and the first lower-base portion, and each of the pool bottom portion comprises a second upper-base portion, a second lower-base portion and a second middle portion defined between the second upper-base portion and the second lower-base portion. The first lower-base portion and the second lower-base portion coincide to define a junction of the pool sidewall portion and pool bottom portion. The first middle portions of the side sheets are successively connected to form a side wall of the above ground pool and the second middle portions are successively connected to form an outer ring of the bottom of the above ground pool. The second upper-base portions of the pool bottom portions are respectively connected to the edge portions of the bottom sheet. In the above ground pool of the present invention, joints are moved to a side wall of the swimming pool or the bottom of the swimming pool as much as possible, thereby reducing the length of joints passing through a heavily stressed area to the greatest extent, simplifying production processes, reducing costs, and reducing the probability of water leakage from the above ground pool.

First claim

What is claimed is:

1. A above ground pool comprising:
a flexible pool body comprising:
a polygonal bottom sheet, comprising a plurality of edge portions; and
a plurality of side sheets, each of the side sheets being of an integral structure and comprising a pool sidewall portion and a pool bottom portion, and each of the pool sidewall portions and each of the pool bottom portions being in the shape of an isosceles trapezoid,

wherein each of the pool sidewall portions comprises a first upper-base portion, a first lower-base portion and a first middle portion defined between the first upper-base portion and the first lower-base portion, and each of the pool bottom portions comprises a second upper-base portion, a second laver-base portion and a second middle portion defined between the second upper-base portion and the second lower-base portion; the first lower-base portions and the second lower-base portion coincide to define a junction of the pool sidewall portion and pool bottom portion; and
wherein the first middle portions are successively connected to form a side wall of the above ground pool, and the second middle portions are successively connected to form an outer ring of the bottom of the above ground pool; and the second upper-base portions of the pool bottom portions are respectively connected to the edge portions of the bottom sheet.

2. The above ground pool of claim 1 , wherein the side sheets are connected to one another by welding, and the side sheets are connected to the bottom sheet by welding to form the pool body.

3. The above ground pool of claim 2 , wherein the plurality of edge portions of the polygonal bottom sheet are respectively welded to the pool bottom portions of the side sheets, thereby forming corresponding first welding seams near the second upper-base portions, and a width of each of the first welding seams is 1.5±0.5 cm.

4. The above ground pool of claim 2 , wherein the second middle portions of the side sheets are connected to one another by welding and form second welding seam, and a width of each of the second welding seams is 2-3 cm.

5. The above ground pool of claim 2 , wherein the first middle portions of the side sheets are connected to one another by welding and form third welding seam, and a width of each of the third welding seams is 3±0.5 cm.

6. The above ground pool of claim 4 , wherein the second welding seams is in a shape of a trapezoid, each of the second welding seams comprising a third upper-base and a third lower-base, a length of the third upper-base is 2 cm, and a length of the third lower-base is 3 cm.

7. The above ground pool of claim 2 , wherein the polygonal bottom sheet is an equilateral polygon; and a ratio of a height of the isosceles trapezoid of the pool bottom portion of the respective side sheet to an apothem of the equilateral polygon of the bottom sheet is 1:10-1:15.

8. The above ground pool of claim 1 , wherein the bottom sheet is made of a PVC material; and each of the side sheets is made of a fabric PVC.

9. The above ground pool of claim 1 , further comprising: a circular inflatable ring welded to the first upper-base, and the above ground pool forms a self-elevating pool.

10. An above ground pool comprising:
a flexible pool body, wherein the pool body comprises:
one or more main splice sheets, each of the one or more splice sheets comprising an intermediate portion and first and second side portions disposed on two opposite ends of the intermediate portion, each of the one or more main splice sheets comprising two first edge portions spliced to one another, the intermediate portions of the one or more main splice sheets being connected to one another to form a pool bottom portion, the first side portions being connected to one another to form a first pool sidewall portion, the second side portions being connected to one another to form a second pool sidewall portion; and
a plurality of end sheets each of which comprises a second edge portion and a third edge portion, wherein the second edge portions of the end sheets are shorter than the first edge portion and are connected to the pool bottom portion of the one or more main splice sheets;
wherein the pool body further comprises a plurality of corner sheets, each corner sheet of the plurality of corner sheets being located between the end sheet and the pool sidewall portion, each of the corner sheets comprising two fourth edge portions, and one of the two fourth edge portions is connected to the respective third edge portion of the respective end sheet, and another one of the two fourth edge portions is connected to the pool sidewall portion of the one or more main splice sheets, so that the corner sheet is connected between the respective end sheet and the respective pool sidewall portion of the one or more main splice sheets.

11. The above ground pool of claim 10 , wherein the one or more main splice sheets, the plurality of end sheets and the plurality of corner sheets are connected to each other by welding.

12. The above ground pool of claim 10 , wherein the one or more main splice sheets are rectangular or square, the plurality of end sheets are rectangular or square, the plurality of corner sheets have a shape similar to a triangle, and the pool body in use is formed into a cuboid or a cube.

13. The above ground pool of claim 10 , wherein a width of a welding seam formed by two adjacent main splice sheets welded to one another is 4±0.5 cm.

14. The above ground pool of claim 11 , wherein a width of a welding seam, formed by welding the plurality of end sheets to the one or more of main splice sheets, is 7±1 cm.

15. The above ground pool of claim 11 , wherein a width of a welding seam formed by welding the plurality of corner sheets to the one or more main splice sheets and a width of a welding seam formed by welding the plurality of corner sheets to the plurality of respective end sheets are both 4±0.5 cm.
