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. An above ground pool, comprising:
a support frame;
a pool body supported by the support frame and having a bottom wall, a pair of side walls and a pair of end walls, the pool body constructed of a flexible material and including:
a plurality of body sheet segments each having a first lengthwise edge and a second lengthwise edge, the first lengthwise edge and the second lengthwise edge each having a first length;
wherein each of the plurality of body sheet segments is coupled to an adjacent one of the plurality of body sheet segments along at least one of the first and second lengthwise edges to form the bottom wall of the pool body;
a pair of end sheet segments each having a lower edge, an upper edge and a pair of side edges, the lower edge of the pair of end sheet segments having a second length;
wherein the lower edge of each of the pair of end sheet segments is coupled to one of the plurality of body sheet segments along one of the first or second lengthwise edges;
wherein the first length is longer than the second length whereby the lower edge of the end sheet segments generally corresponds to a width of the bottom wall of the pool body.

2. The above ground pool of claim 1 , further comprising:
a plurality of corner sheet segments extending between and coupled to one of the pair of end sheet segments and one of the plurality of body sheet segments.

3. The above ground pool of claim 2 , wherein the plurality of corner sheet segments each has a first side border and a second side border, the first side border being coupled to one side edge of the pair of end sheet segments, and the second side border being coupled to one of the first or second lengthwise edges.

4. The above ground pool of claim 1 , wherein each body sheet segment is welded to an adjacent body sheet segment along a length of at least one of the first and second lengthwise edges, respectively.

5. The above ground pool of claim 1 , wherein the plurality of body sheet segments each have a generally rectangular shape.

6. The above ground pool of claim 5 , wherein the pair of end sheets segments each have a generally rectangular shape.

7. The above ground pool of claim 6 , wherein the plurality of corner sheets each has a generally triangular shape and the pool body has a generally cuboid shape.

8. The above ground pool of claim 4 , wherein a width of a welding seam formed between adjacent body sheet segments is about 4±0.5 cm.

9. The above ground pool of claim 8 , wherein a width of a welding seam, formed at an attachment of a respective one of the end sheet segments to the bottom wall is about 7±1 cm.

10. The above ground pool of claim 9 , wherein a width of a welding seam formed by welding the plurality of corner sheet segments to the body sheet segments and a width of a welding seam formed by welding the plurality of corner sheet segments to a respective one of the end sheet segments are 4±0.5 cm.

11. The above ground pool of claim 1 , further comprising:
a plurality of pull belts having a first end portion coupled to the bottom wall and a second end portion configured to attach to a portion of the support frame.

12. The above ground pool of claim 11 , wherein the support frame has an upper portion configured to connect to a side wall of the pool body and a lower portion configured to engage ground;
wherein the second end portion of the plurality of pull belts is configured to connect to the lower portion of the support frame.

13. The above ground pool of claim 12 , wherein the plurality of pull belts are generally parallel to one another and extend generally along a length of each of the side walls of the pool body.

14. An above ground pool comprising:
a support frame having a first end configured to engage a flexible pool body and a second end configured to engage ground;
the flexible pool body supported by the support frame and including:
a plurality of body sheet portions each having a pair of opposing side edge portions, each of the body sheet portions being coupled to an adjacent body sheet portion along one of the side edge portions to form a pool bottom portion;
a pair of end sheet portions each coupled to one of the side edge portions;
a plurality of corner sheets each extending between one of the body sheet portions and one of the end sheet portions, each of the end sheet portions has a lower edge portion that is coupled to one of the side edge portions of one of the body sheet portions;
the lower edge portion of each of the end sheet portions having a first length;
the side edge portions of each of the plurality of body sheet portions having a second length;
wherein the second length is greater than the first length.

15. The above ground pool of claim 14 , wherein each of the body sheet portions has a middle portion and a pair of opposing end portions, wherein the middle portion of each of the body sheet portions corresponds to a section of the pool bottom portion.

16. The above ground pool of claim 15 , where the opposing end portions of the body sheet portions each correspond to a respective sidewall of the flexible pool body.

17. The above ground pool of claim 16 , further comprising:
a plurality of pull belts coupled to the flexible pool body for securing the plurality of body sheet portions to the support frame;
wherein each body sheet portion has a pair of pull belts secured to the middle portion with each of the pull belts extending outwardly beyond a perimeter of a respective one of the sidewalls of the flexible pool body.

18. The above ground pool of claim 17 , further comprising:
