Abstract

An inflatable cushioning system with separate inflatable cushioning chambers a common tool guideway and a common air inlet. The inflatable cushioning chambers each have an inflation port. The common air inlet is in fluid communication with each of the inflatable cushioning chambers. During inflation, pressurized air is inserted into the common air inlet. The pressurized air then enters the individual cushioning chambers through the inflation ports. The inflatable cushioning system is inflated using a multi-purpose inflation tool having a body with a main portion and a second portion, the second portion being connected to the main portion and both portions having hollow interiors. The second portion of the tool having a connecting means for connecting the tool to an external pressurized air source. The tool also having a blade connected to said main portion for cutting the tool guideway as the tool is advanced through the tool guideway. The tool also has a plurality of apertures in the main portion for providing fluid into the inflatable cushioning system.

Claims

1. A method for charging an inflatable cushion systems, said system having a plurality of inflatable chambers having one-way inflation valves aligned in rows along a common tool guideway, said method comprising:

inserting into said common tool guideway a tool comprising;

1) a main hollow body having an axis, a tapered closed first end and a plurality of paired openings spaced in the direction of the axis at a distance corresponding to the spacing of said chambers;

2) a second body portion attached to said main hollow body at an angle to said first axis and having a longitudinal opening communicating with said hollow portion of said main hollow body;

introducing a fluid through said second body portion and through said main hollow body into said inflatable chambers; and

separating said rows of inflatable chambers along said common tool guideway to advance said tool along said plurality of inflatable chambers.

2. A method according to claim 1 wherein said fluid is gas.

3. A method according to claim 1 wherein said gas is air.

4. A method according to claim 1 wherein said introducing of said fluid is continuous.

5. A method according to claim 1 wherein said introducing of said fluid is in pulses.

6. A multi-purpose tool for inflating an inflatable cushion system, said system having a) a plurality of inflatable chambers having one-way inflation valves and b) a common tool guideway between paired rows of chambers, said tool comprising:

1) a main hollow body having an axis, a tapered closed first end and a plurality of paired openings spaced in the direction of the axis a distance corresponding to the spacing of said chambers;

2) a second body portion attached to said main hollow body at an angle to said first axis and having a longitudinal opening communicating with said hollow portion of said main hollow body; and

3) means for separating said common tool guideway after said chambers have been inflated.

7. A multi-purpose tool according to claim 6 wherein said means for separating constitutes a knife blade mounted at a juncture of said main body portion and said second body portion.

8. A multi-purpose tool according to claim 6 wherein said means for separating constitutes a protrusion from said main hollow body between a juncture of said main body and second portion and a first pair of openings.

9. A multi-purpose tool according to claim 6 wherein said main hollow body is cylindrical.

10. A multi-purpose tool according to claim 6 wherein said main hollow body is oval.

11. A multi-purpose tool according to claim 6 wherein said plurality of paired openings are elongated and bridge two or more of said chambers.
