Abstract

An air distribution system includes a portable air compressor feeding a flexible branched air distribution hose. The hose includes branch air lines branching from a main air line. The branch air lines have multiple exhaust ends on distal ends of corresponding branch air lines, distal from the main air line. The exhaust ends are adapted for mounting to an air inflatable structure in fluid communication therewith. The main air line has an infeed end adapted for mounting to the compressor in fluid communication therewith.

Description

    CROSS REFERENCE TO RELATED APPLICATION
  • This application claims priority from Canadian Patent Application filed Dec. 1, 2006 and U.S. Provisional Patent Application No. 60/752,010 filed Dec. 21, 2005 entitled Air Distribution System for Inflating Pneumatic Structures.
  • FIELD OF THE INVENTION
  • This invention relates to the field of inflatable structures such as inflatable tents and in particular to an air distribution system for simultaneously inflating a multiplicity of such structures.
  • BACKGROUND OF THE INVENTION
  • In the prior art it is known to provide pneumatic structures such as the inflatable tents sold by Airzone Recreation Inc. of Kelowna, British Columbia under the product names Goldfinch, Ptarmigan, Osprey and Condor, and as described in their U.S. Pat. No. 6,263,617. It has come to be recognized that pneumatic structures such as inflatable tents and their derivatives have a utility well beyond that of merely recreational and camping, for example, in humanitarian relief wherein a large number of portable structures may have to be transported and erected quickly and efficiently, and other such applications requiring a multiplicity of portable structures which may be efficiently carried and easily erected on a large scale, such as for use by the military.
  • Although it is very useful for individual consumers to provide a small compressor or a small bottle of compressed gas to inflate a single inflatable tent for their personal use, for use on a large scale where a plurality of pneumatic structures such as inflatable tents need to be inflated simultaneously or at least in quick succession, the system of the present invention incorporates a portable compressor such as driven by a small normally aspirated, gasoline fuelled, engine so as to drive a large volume of relatively low pressure air, and it is an object of the present invention to provide a branched air distribution hose mountable in fluid communication with such a portable compressor.
  • SUMMARY OF THE INVENTION
  • An air distribution system includes a portable air compressor feeding a flexible branched air distribution hose. The hose includes branch air lines branching from a main air line. The branch air lines have multiple exhaust ends on distal ends of corresponding branch air lines, distal from the main air line. The exhaust ends are adapted for mounting to an air inflatable structure in fluid communication therewith. The main air line has an infeed end adapted for mounting to the compressor in fluid communication therewith.
  • The main air line has a first internal diameter and the branch air lines have a second internal diameter. The second internal diameter is smaller than the first internal diameter whereby the main air line acts as a ballast feeding the branch air lines. The main air line may be substantially linear when inflated and the branch air lines may branch from the main air line at substantially right angles to the main air line. The branch air lines may branch in oppositely disposed pairs from the main air line, and the pairs are spaced apart along the main air line. The branch air lines may be substantially linear when inflated.
  • BRIEF DESCRIPTION OF THE DRAWINGS
  • With reference to the drawings, wherein similar characters of reference denote corresponding parts in each view, three figures are provided, and in particular:
  • FIG. 1 is a diagrammatic plan view of the present invention.
  • FIG. 2 is a diagrammatic plan view of a second embodiment of the present invention.
  • FIG. 3 is a diagrammatic plan view of a third embodiment of the present invention.
  • DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
  • The system according to the present invention includes a portable compressor 10 demountably coupled to a branched air conduit having a main trunk air line 12, the smaller inside diameter branched ends 12 a of which are mountable to a corresponding plurality of inflatable structures 14. In one embodiment, the branched main trunk line 12 is a flexible air hose having a diameter of approximately ½ inch inside diameter and branched lines 12 a branching in fluid communication from the main trunk so that the ends of which may be mounted to the corresponding inflatable structures 14.
  • Thus with the base end 12 b of the main trunk 12 mounted to the compressed air outflow port 10 a of compressor 10, and with the air conduit spread out, for example fully unfurled from a furled storage and transportation mode, the ends of the branches 12 a are coupled for example with the inlet valves of the corresponding inflatable tents or other pneumatic structures. With the compressor engine started, so that the compressor supplies for example 12 CFM with the pressure of approximately 18 PSI, or at least in the range of 15 to 20 PSI, the plurality of inflatable tents may be simultaneously inflated via the branched air conduit.
  • There is a substantial reduction in airflow from the main trunk air line 12 (½″) inside diameter to the smaller lines connecting to the tent that acts somewhat like a “ballast” allowing even flow of air to each and every tent. The line quickly pressurizes and flows through evenly to all the smaller branch lines 12 a allowing a seamless and even inflating procedure.
  • As will be apparent to those skilled in the art in the light of the foregoing disclosure, many alterations and modifications are possible in the practice of this invention without departing from the spirit or scope thereof. Accordingly, the scope of the invention is to be construed in accordance with the substance defined by the following claims.
