Inflatable floating device

Abstract

An inflatable floating device includes an inflatable body and a steering device. The inflatable body includes front and rear ends, top and bottom sides, and a through hole extending through the top and bottom sides. The steering device is mounted on the inflatable body, and includes a rotary shaft extending through the through hole, a steering handle connected to a top end of the rotary shaft, and a rudder plate connected to a bottom end of the rotary shaft.

1 . An inflatable floating device comprising: 
 an inflatable body including front and rear ends, top and bottom sides, and a through hole extending through said top and bottom sides; and    a steering device mounted on said inflatable body, and including a rotary shaft extending through said through hole, a steering handle connected to a top end of said rotary shaft and disposed outwardly of said top side, and a rudder plate connected to a bottom end of said rotary shaft and disposed outwardly of said bottom side.    
   
   
       2 . The inflatable floating device as claimed in  claim 1 , wherein said steering device further includes a bearing tube inserted into said through hole around said rotary shaft, said rotary shaft being received rotatably within said bearing tube.  
   
   
       3 . The inflatable floating device as claimed in  claim 2 , wherein said inflatable body further includes first, second and third inflatable portions, said steering device being mnounted on said third inflatable portion, said third inflatable portion being connected to and being disposed between said first and second inflatable portions.  
   
   
       4 . The inflatable floating device as claimed in  claim 1 , wherein said rudder plate is changeable between a first configuration, in which said rudder plate lies in a plane substantially aligned with an axis of said rotary shaft, and a second configuration, in which said plane of said rudder plate is angled relative to said rotary shaft.  
   
   
       5 . The inflatable floating device as claimed in  claim 1 , wherein said rudder plate is detachable from said rotary shaft to place said rudder plate between a first configuration, in which said rudder plate lies in a plane substantially aligned with an axis of said rotary shaft, and a second configuration, in which said plane of said rudder plate is angled relative to said rotary shaft.  
   
   
       6 . The inflatable floating device as claimed in  claim 2 , wherein said bearing tube has a bottom seat proximate to said bottom side of said inflatable body, said inflatable body further including a first retaining unit provided on said bottom side to engage said bottom seat so as to prevent said bearing tube from rotating.  
   
   
       7 . The inflatable floating device as claimed in  claim 6 , wherein said bearing tube further has an externally threaded section proximate to said top side of said inflatable body, and a limiting plate which has an internally threaded hole attached to said externally threaded section.  
   
   
       8 . The inflatable floating device as claimed in  claim 2 , further comprising a restricting member provided proximate to said bottom side of said inflatable body to restrict said rotary shaft to rotate within a limited angle.  
   
   
       9 . The inflatable floating device as claimed in  claim 8 , wherein said restricting member is provided on said bearing tube proximate to said bottom side.  
   
   
       10 . The inflatable floating device as claimed in  claim 6 , further comprising two diametrically opposed arcuate members formed on said bottom seat around said rotary shaft, said rotary shaft having a radial projection projecting between said arcuate members.  
   
   
       11 . The inflatable floating device as claimed in  claim 5 , wherein said rotary shaft further has a first fixed portion on said bottom end of said rotary shaft, said rudder plate having a second fixed portion connected to said first fixed portion.  
   
   
       12 . The inflatable floating device as claimed in  claim 1 , wherein said inflatable body further includes a tail wing connected pivotally to said rear end.
