Shock absorbing device for air-column sheet

Abstract

The present invention discloses a shock absorbing device for an air-column sheet comprising a plurality of adjacently coupled air columns, and each air column has an inflating/check valve and forms an independent inflating space, wherein the air columns are thermally pressed into several bending points, so that the air-column sheet can be bent to 90 degrees, 180 degrees, or even 360 degrees when the bending points are connected. The bent air-column sheet forms a continuous shock absorbing wall along the left, right, up, and down directions, which can be used as an internal air pad of a box, and the width and appearance of air columns can be changed to form a flat or non-flat internal air pad for improving the shock absorbing function and providing a special function of reinforcing the protection on both sides or inside by partitions from by the bent internal air pad.

1 . A shock absorbing device for an air-column sheet, having a plurality of adjacently coupled air columns, and each air column comprising: an inflating/air check valve for forming an independent inflating space; and a bending point for coupling the upper and lower portion of said each air column for forming a shock absorbing wall.  
   
   
       2 . The shock absorbing device for an air-column sheet of  claim 1 , wherein said each air column comes with an equal length, an unequal length, or a combination of lengths.  
   
   
       3 . The shock absorbing device for an air-column sheet of  claim 1 , wherein said each air column is selectively inflated or not inflated.  
   
   
       4 . The shock absorbing device for an air-column sheet of  claim 1 , wherein said each air column has an equal width, an unequal width, or a combination of widths.  
   
   
       5 . The shock absorbing device for an air-column sheet of  claim 1 , wherein said each air column includes two sets of bending points, and a short bridge is formed between two sets of bending points to be bent to form a reinforcing wall.  
   
   
       6 . The shock absorbing device for an air-column sheet of  claim 1 , wherein said air-column sheet includes a cut line for cutting and separating a portion of said air column to be enclosed to form a container.  
   
   
       7 . The shock absorbing device for an air-column sheet of  claim 1 , wherein said bending point is in a circular shape, a square shape, a triangular shape, an elliptic shape, or other irregular shapes.  
   
   
       8 . The shock absorbing device for an air-column sheet of  claim 1 , wherein said each air column has two or more bending points.  
   
   
       9 . The shock absorbing device for an air-column sheet of  claim 1 , wherein said air column is linear, curved, or a combination of both.  
   
   
       10 . The shock absorbing device for an air-column sheet of  claim 1 , wherein said bending points are arranged to form a cut line that can be torn apart.
