Abstract

An inflatable product is provided including a top sheet, a bottom sheet, a lateral confining sheet, and an internal connecting sheet. A peripheral edge of the top sheet is connected to an upper edge of the lateral confining sheet, and a peripheral edge of the bottom sheet is connected to a lower edge of the lateral confining sheet, forming an inflatable chamber. An upper edge of the internal connecting sheet is connected to the top sheet, a lower edge of the internal connecting sheet is connected to the bottom sheet, and a connecting part of the internal connecting sheet, located between the upper edge and the lower edge of the internal connecting sheet, is connected to the lateral confining sheet along at least one welding seam. The at least one welding seam may form at least one embossment on an outside of the inflatable product.

First claim

What is claimed is:

1. An inflatable product comprising:
a top sheet, a bottom sheet, and a confining sheet having an annular shape and comprising an upper edge connected to a peripheral edge of the top sheet and a lower edge connected to a peripheral edge of the bottom sheet, such that an inflatable chamber is defined between the top sheet and the bottom sheet and bounded by the confining sheet;
at least one connecting sheet comprising:
an upper edge welded to the top sheet along an upper welding seam parallel to the peripheral edge of the top sheet,
a lower edge welded to the bottom sheet along a lower welding seam parallel to the peripheral edge of the bottom sheet, and
a connecting part welded to the confining sheet along at least one lateral welding seam between the upper welding seam of the upper edge and the lower welding seam of the lower edge.

2. The inflatable product according to claim 1 , wherein the at least one connecting sheet comprises:
a first connecting sheet, a second connecting sheet, a third connecting sheet, and a fourth connecting sheet, respectively connected to the top sheet along upper welding seams substantially parallel to a first side, a second side, a third side, and a fourth side of the top sheet, and respectively connected to the bottom sheet along lower welding seams substantially parallel to a first side, a second side, a third side, and a fourth side of the bottom sheet.

3. The inflatable product according to claim 1 , wherein the at least one connecting sheet comprises an annular connecting sheet.

4. The inflatable product according to claim 3 , wherein the inflatable product is substantially polygonal, and wherein the connecting sheet comprises a notch formed therein at a location corresponding to each of a plurality of corners of the inflatable product.

5. The inflatable product according to claim 1 , wherein the lateral welding seam is substantially parallel to each of the upper welding seam and the lower welding seam.

6. The inflatable product according to claim 1 , wherein the lateral welding seam comprises a closed shape.

7. The inflatable product according to claim 1 , wherein the lateral welding seam comprises one of a wavy line, a zig-zag line, or a substantially straight line.

8. The inflatable product according to claim 1 , further comprising:
at least one tensioning member disposed in the inflatable chamber and comprising at least one upper edge connected to the top sheet and at least one lower edge connected to the bottom sheet.
