Dual tube float device

Abstract

The present invention comprises two V-shaped tubes held in a nested and tensioned relationship with each other such that the assembly is free of tensioning straps or rigid supports while easily maintaining its relative legs angled relationship effectively supporting in fishing activity in wave agitated lakes and bodies of water persons weighing up to and over 250 pounds.

I claim:  
     
         1 . An inflatable float device adapted to support upright above water at least the upper torso of a person while their legs are immersed therein comprising: 
 (a) at least two inflatable tubes adapted to be maintained, in an inflated state, in a side by side relationship such that a first tube forms an outer edge of the V-shape, a second tube forms an inner edge of the V-shape, and the total side to side width of the tubes in at least a legs part of the V-shape is greater than the side view height of that legs part; and    (b) a flexible sheet or net covering stretched around the tubes is adapted to, in the inflated state of the device, maintain the leg parts in substantially a V-shape against side to side deflection in the plane of the V-shape.    
     
     
         2 . The device of  claim 1  wherein along at least a portion of a contact surface between the tubes such adjacent tubes are integrally and effectively connected to resist relative movement of the adjacent tubes.  
     
     
         3 . The device of  claim 1  wherein the tubes are inflated to less than 5 psig.  
     
     
         4 . The device of  claim 1  wherein the tubes are inflated to less than 3 psig.  
     
     
         5 . The device of  claim 1  wherein the second tube in a vertex part of the V-shape has a side view height substantially greater than that the height of the adjacent tube in that vertex part.  
     
     
         6 . The device of  claim 1  wherein leg parts of the V-shape have substantially the same length measured from the vertex part.  
     
     
         7 . The device of  claim 6  wherein the leg parts' length is two feet or more.  
     
     
         8 . The device of  claim 6  wherein the leg parts' length is three feet or more.  
     
     
         9 . The device of  claim 1  wherein the side to side width is less than about three feet.  
     
     
         10 . The device of  claim 1  wherein the adaptation to support the person comprises a seat supportively connected at opposite ends to at least the legs part of the V-shape.  
     
     
         11 . The device of  claim 1  wherein the covering comprises one or more of the group of webbed or latticed flexible material, porous woven material, non-porous woven material, and non-porous polymer sheets.  
     
     
         12 . The device of  claim 11  wherein the covering comprises at least a webbed or latticed material along at least an underside part of the covering such that water will easily drain from a cavity formed between the tubes and the covering when the device is in the inflated state.  
     
     
         13 . The device of  claim 1  wherein separate means for user access to inflate and deflate the tubes is located on an upper part of the device.  
     
     
         14 . An inflatable float device comprising: 
 (a) at least two inflatable tubes adapted to be maintained, in an inflated state, in a side by side relationship such that a first tube forms an outer edge of a V-shape, an I-shape or an O-shape, a second tube forms an inner edge of those shapes, and the total side to side width of the tubes in at least a major part of the shapes is greater than the side view height of that major part; and    (b) a flexible sheet or net covering stretched around the tubes is adapted to, in the inflated state of the device, maintain the major parts in substantially its original shape against side to side deflection in the major part.    
     
     
         15 . The device of  claim 14  wherein along at least a portion of a contact surface between the tubes such adjacent tubes are integrally and effectively connected to resist relative movement of the adjacent tubes.  
     
     
         16 . The device of  claim 14  wherein the second tube in a vertex part of the V-shape has a side view height substantially greater than that the height of the adjacent tube in that vertex part.  
     
     
         17 . The device of  claim 14  wherein the covering comprises one or more of the group of webbed or latticed flexible material, porous woven material, non-porous woven material, and non-porous polymer sheets.  
     
     
         18 . The device of  claim 17  wherein the covering comprises at least a webbed or latticed material along at least an underside part of the covering such that water will easily drain from a cavity formed between the tubes and the covering when the device is in the inflated state.  
     
     
         19 . The device of  claim 14  wherein the covering comprises one or more of the group of webbed or latticed flexible material, porous woven material, non-porous woven material, and non-porous polymer sheets.  
     
     
         20 . The device of  claim 14  wherein two I-shaped devices are held apart in the plane of their side to side orientation by means of one or more rigid supports.
