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.
Claims10
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.
