Inflatable barrier

Abstract

An inflatable barrier with an integral, triple chamber construction. An upper air chamber of relatively greater volume may be configured in any convenient shape such as pyramids, cylinders, cubes and barricades as suitable for use at combat sports venues. A centrally disposed, water-filled chamber provides sufficient weight to resist displacement of the barrier to normal impacts. A peripheral lower air chamber surrounds the water-filled chamber to stabilize lateral support and to maintain an upright orientation of the barrier.

1 . An inflatable barrier comprising: 
 a first chamber generally for defining the overall shape and size of the barrier;    a ground engaging second chamber centrally positioned beneath and connected to said first chamber; and    a ground engaging third chamber peripherally surrounding said second chamber and being integrally connected to said first and second chambers;    whereby said first chamber may be fully inflated with air to establish the overall shape and size of the barrier, said second chamber may be filled with a weighting fluid of sufficient mass to hold said first chamber at a preselected ground location, and said third chamber may be fully inflated with air to stabilize the barrier from side impacts.    
   
   
       2 . The barrier as in  claim 1 , said first, second and third chambers being integrally fabricated of durable, water and air impermeable fabric.  
   
   
       3 . The barrier as in  claim 1 , the shape of said first chamber being selected from the group consisting of pyramids, cones, cubes, cylinders, rectangular blocks, domes, hemispheres, and regular and irregular volumetric forms.  
   
   
       4 . The barrier as in  claim 1 , the shape of said second chamber in top plan view being scaled down from the top plan view of said first chamber such that the out periphery of said second chamber is spaced inwardly from the outer periphery of said first chamber.  
   
   
       5 . The barrier as in  claim 1 , said second chamber comprising a water bladder disposed beneath the centroid of said first chamber.  
   
   
       6 . The barrier as in  claim 1 , the shape of said second chamber being selected from the group consisting of volumetric triangles, rectangles, squares and circles.  
   
   
       7 . The barrier as in  claim 1 , said third chamber shaped to correspond to the outer periphery of said first chamber.  
   
   
       8 . The barrier as in  claim 1 , said third chamber being generally tubular in form and shaped as to frame the periphery of said second chamber.  
   
   
       9 . The barrier as in  claim 1 , wherein the volume of said third chamber falls in the range or 80 to 130% of the volume of said second chamber.  
   
   
       10 . The barrier as in  claim 1 , further including first, second and third fill valve corresponding respectively to said first, second and third chambers whereby said first and third chambers may be inflated with air and said second chamber may be filled with water.
