Abstract

A pool apparatus configured to carry liquids has a side wall and a bottom surface. The side wall has a plurality of structure drawstrings, an outer side wall, and an inner side wall. Two sides of the structure drawstrings draw respectively the outer side wall and the inner side wall, so as to maintain a predetermined shape of the pool apparatus. The structure drawstrings include a main drawstring portions and at least two branch drawstring portions. The main drawstring portions have a first main string side configured to connect a first branch drawstring side of the at least two branch drawstrings. A second branch string side of the at least two branch drawstrings connects respectively to different positions of the outer side wall and the inner side wall.

First claim

What is claimed is:

1. A pool apparatus configured to carry liquids, comprising:
at least one side wall, the side wall comprising at least one structure drawstring, an outer side wall, and an inner side wall, wherein the at least one structure drawstring draws the outer side wall and the inner side wall, so as to maintain a predetermined shape of the pool apparatus, the at least one structure drawstring comprising a main drawstring portion and at least two branch drawstring portions, the main drawstring portion having a first main drawstring side configured to connect with a first branch drawstring side of the at least two branch drawstrings, and second branch drawstring sides of the at least two branch drawstrings connect respectively to different positions of the outer side wall or the inner side wall, each second branch drawstring side being disposed at a non-parallel orientation to the inner or outer side wall where each second branch drawstring side is connected to the inner side wall or the outer side wall;
a bottom surface connecting to the side wall, so as to form together to be one portion of the structure body for carrying liquids; and
wherein the predetermined shape includes one or more turning portions;
wherein the at least one structure drawstring is disposed along the one or more turning portions;
a plurality of drawstrings, each drawstring of the plurality of drawstrings comprising two sides connecting respectively to the inner side wall and the outer side wall, configured at one or more straight portions of the predetermined shape;
wherein each of the plurality of drawstrings is generally perpendicular to the corresponding inner side wall and the corresponding outer side wall whereto each of the plurality of drawstrings is connected.

2. The pool apparatus as claim 1 , wherein the at least two branch drawstring portions connect jointly with the first main drawstring side wall, and during inflation at the inside of the side wall, the at least two branch drawstring portions separate from the connection part of the main drawstring portions with a first angle, connecting respectively to different positions of the outer side wall or the inner side wall, so that the outer side wall or the inner side wall with the connection portion of the structure drawstrings have drawing forces in at least two directions, composing a more stable stereotype structure.

3. The pool apparatus as claim 2 , wherein the connection angles between the branch drawstring portions and the outer side wall and the angles between the branch drawstring portions and the inner side wall are smaller than 80 degrees.

4. The pool apparatus as claim 2 , wherein the side wall has more than two structure drawstrings, the more than two structure drawstrings being substantially parallel and separating with a distance and drawing respectively different parts of the inner side wall and the outer side wall, such that after the inflation of the pool apparatus, the inner side wall and the outer side wall maintaining fixed shapes.

5. The pool apparatus as claim 4 , wherein the side wall forms a closed surrounding wall surface corresponding to the predetermined shape; and wherein, the surrounding wall surface and the bottom surface constitute a carrying space configured to carry liquids.

6. The pool apparatus as claim 5 , wherein the predetermined shape is one of a square, a rectangle, a square with elliptical corners, and a rectangle with elliptical corners.

7. The pool apparatus as claim 2 , wherein the structure drawstrings further comprising at least two sub-branch drawstring portions, and one end of the at least two sub-branch drawstring portions connecting to the main drawstring portions, and during inflation at inside of the side wall, the at least two sub-branch drawstring portions separating from the connection parts of the main drawstring portions with a second angle, and connecting respectively to different positions of the outer side wall or the inner side wall, such that the connection portions of the outer side wall or the inner side wall, with the structure drawstrings having drawing forces in at least two different directions, composing a more stable stereotype structure.

8. The pool apparatus as claim 2 , wherein the main drawstring portions of the structure drawstrings and the branch drawstring portions have shapes substantially polygon strips respectively, and the shapes have at least one dip, so that airs may circulate with each other on the two sides of the structure drawstrings.

9. The pool apparatus as claim 2 , further comprising a top sheet connecting the plurality of structure drawstrings, and the top sheet, the inner side wall, the outer side wall and the bottom surface constituting an air chamber, holding up the side wall during the inflation, so as to form a space for carrying liquids with the bottom surface.

10. The pool apparatus as claim 1 , wherein the bottom surface and the side wall are flexible tapes.

11. The pool apparatus as claim 9 , wherein a high frequency manner is used to weld between the flexible tapes.

12. A pool apparatus comprising:
a side wall having an outer side wall, an inner side wall and a plurality of structure drawstrings, wherein the structure drawstrings draw the outer side wall and the inner side wall, so as to maintain the pool apparatus to keep a predetermined shape, and the structure drawstrings comprising a main drawstring portion and at least two branch drawstring portions, and the main drawstring portion having a first main drawstring side configured to connect with a first branch drawstring side of the at least two branch drawstrings, and a second branch drawstring side of the at least two branch drawstrings connecting respectively to different positions of the outer side wall or the inner side wall, each second branch drawstring side being disposed at a non-parallel orientation to the inner or outer side wall where each second branch drawstring side is connected to the inner side wall or the outer side wall;
a top sheet constituting a surrounding close shape, and the top sheet connecting the outer side wall along the outer periphery of the surrounding close shape, and the top sheet connecting the inner side wall along the inner periphery of the surrounding close shape;
a bottom surface connecting to the side wall, and after the inflation of the side wall, the bottom surface and the side wall constitutes a space for carrying liquids; and
wherein the predetermined shape includes one or more turning portions; and
wherein the plurality of structure drawstrings is disposed along the one or more turning portions;
a plurality of drawstrings, each drawstring of the plurality of drawstrings comprising two sides connecting respectively to the inner side wall and the outer side wall, configured at one or more straight portions of the predetermined shape;
wherein each of the plurality of drawstrings is generally perpendicular to the corresponding inner side wall and the corresponding outer side wall whereto each of the plurality of drawstrings is connected.

13. The pool apparatus as claim 12 , wherein the connection angles between the branch drawstring portions and the outer side wall and the angles between the branch drawstring portions and the inner side wall are smaller than 80 degrees.

14. The pool apparatus as claim 12 , wherein the bottom surface, the top sheet, the outer side wall and the inner side wall mentioned herein are flexible tapes.

15. The pool apparatus as claim 12 , wherein the inside of the side wall comprises at least one air chamber, and air on two sides of the at least one structure
