Abstract

<P>PROBLEM TO BE SOLVED: To implement a multipurpose water tank which is lightweight, handy to carry, so compact that it does not require much space for storage, safe, and stable, and ensures reliability in water imperviousness. <P>SOLUTION: This lightweight, water imperviousness, and stable water tank can be implemented by combining a folding waterproof sheet tank 1 which is unstable in formation in spite of the expected complete water imperviousness and weight reduction, with several divided walls 2 which are stable in formation. When the water pressure is unilaterally imposed, a spacer 4 provided on one side of the inner surface of each divided wall 2 works to maintain the clearance 10 between divided walls 2. After use, all divided walls 2 are removed one after another, and the waterproof sheet tank 1 is made inclined to empty the water out. Since all individual parts are light and small enough to be carried by one person, it is possible to make this stable water tank instantly in any place, and therefore, it has various uses including as a swimming pool for children, an outdoor bathtub for family use, and a quickly-made water reservoir in an emergency. <P>COPYRIGHT: (C)2003,JPO

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention combines a waterproof sheet water tank in which a water tank part is folded and a divided side wall, and integrates them.
Waterproof sheet tank with complete waterproofness but lacks independence when assembled by folding one waterproof sheet, but lacks independence when assembled By integrating the divided water tanks, it is possible to make use of each other's strengths and to make a safe and stable water tank that compensates for the disadvantages. Also, by changing the height of the divided side wall, the length and shape of the joint, and the size of the buttress, the depth of the water tank can be adapted to any polygonal water tank, so children's pool, The range of applications from outdoor baths to emergency water storage tanks is wide. The waterproof sheet is small, and each of the divided water tanks is lightweight and small in size, so that it is easy to carry and store. (B) Assemble the folding waterproof sheet tank (1). (B) Insert the side walls of (2) into the holes (1)
After insertion so that 3) is located at the notch (9), the divided bathtubs are tied together with the tying tool (12). (C) After confirming that the waterproof sheet is kept in a normal state from the upper cutout portion of the divided side wall (2), the hole (13) and the hardware 11 are joined with a string-shaped thing. (D) Inject water from above with a hose. (E) After use, first, one of the divided side walls is taken out, the rising portion of the waterproof sheet is broken, and the water inside is discharged. (F) Drain the remaining water in the waterproof sheet tank completely, pull out all the divided side walls, and then dry and fold the waterproof sheet in the same manner as ordinary laundry, and integrate it with the divided side walls. And store it.

Claims (1)

[Claim 1] A single waterproof sheet is folded to form a water tank, and a divided side wall is inserted into a rising portion of the side wall, thereby tightening the water tank and the side wall, and bonding the side walls to each other. This will reinforce the rising part of the side of the waterproofing tank and make the side stand by itself. In addition, spacers are provided at two locations to secure clearance when water pressure acts on the inner side of the lower part of the waterproof sheet insertion portion clearance on the side wall. A triangular foldable buttress is provided outside of the divided side walls to increase the stability and independence against falling when water is added by increasing the contact surface while resisting the internal water pressure.
