Propeller driven surfing device

Abstract

A propeller driven surfing device includes a buoyant body having an outer contour divergent from a nose end to a front trunk segment, a rearmost surface which has a water outlet port that extends forwardly to form a water passage, and a water intake port that extends from a bottom surface to be communicated with the water passage. A drive motor is disposed in the buoyant body, and has an output shaft which extends into the passage to drive a propeller disposed in the passage. A power supply is disposed in the buoyant body and is operably coupled to the drive motor.

1 . A propeller driven surfing device comprising:
 a buoyant body having nose and tail ends opposite to each other in a longitudinal direction, and front and rear trunk segments which are interposed between said nose and tail ends, and which are respectively proximate to said nose and tail ends said buoyant body having deck and bottom surfaces which are opposite to each other in an upright direction, and which extend respectively from said nose end to said tail end, said nose end and said front trunk segment being integrally formed and being configured to have an outer contour that is divergent from said nose end to said front trunk segment, and that is streamlined towards said front trunk segment to have an uninterrupted surface, said tail end having a rearmost surface which extends in the upright direction, and which has a water outlet port that extends between said deck and bottom surfaces and forwardly to terminate at a partition wall surface so as to form a water passage, said bottom surface at said tail end defining a water intake port which is disposed rearwardly of said partition wall surface, and which extends towards said deck surface to be communicated with said water passage;   a drive motor which is disposed in said rear trunk segment between said deck and bottom surfaces, and which includes an output shaft that extends outwardly of said partition wall surface and into said water passage so as to be disposed downstream of said water intake port;   a power supply which is disposed in said front trunk segment proximate to said deck surface, and which is operably coupled to said drive motor; and   a propeller which is driven by said drive motor, and which is disposed in said water passage between said rearmost surface and said partition wall surface.   
   
   
       2 . The propeller driven surfing device according to  claim 1 , wherein said front trunk segment has a cavity which extends from said deck surface towards said bottom surface for receiving said power supply. 
   
   
       3 . The propeller driven surfing device according to  claim 2 , wherein said buoyant body further has a cover plate which is disposed to cover said cavity and which is flush with said deck surface. 
   
   
       4 . The propeller driven surfing device according to  claim 2 , further comprising a control member which is disposed in said cavity and which is electrically coupled to said drive motor and said power supply so as to control operation of said drive motor. 
   
   
       5 . The propeller driven surfing device according to  claim 4 , further comprising an operating member which is electrically coupled to said control member, and which is disposed to be movable relative to said buoyant body so as to be operable to control operation of said control member. 
   
   
       6 . The propeller driven surfing device according to claim  5 , further comprising a cable which is electrically connected to said operating member and said control member. 
   
   
       7 . The propeller driven surfing device according to  claim 5 , wherein said operating member controls said control member over a wireless network using the Bluetooth protocol. 
   
   
       8 . The propeller driven surfing device according to  claim 1 , wherein said drive motor has a coupler which is disposed to interconnect said output shaft and said propeller, said buoyant body further having a supporting seat which is secured in said water passage and which has an axial hole for passage of said coupler so as to support said coupler. 
   
   
       9 . The propeller driven surfing device according to  claim 1 , further comprising a stabilizing unit which includes a pair of connecting shafts that extend from said decking surface laterally to terminate at left and right ends, respectively, and a pair of buoyant barrels that are connected to said left and right ends, respectively, so as to float on water. 
   
   
       10 . The propeller driven surfing device according to  claim 7 , further comprising a stabilizing unit which includes a head post that is disposed adjacent to said nose end and that extends from said decking surface in the upright direction to terminate at an upper end, and a handlebar that has a middle portion connected to said upper end, and two handgrip portions extending laterally from said middle portion, said operating member being disposed on one of said handgrip portions. 
   
   
       11 . The propeller driven surfing device according to  claim 7 , further comprising a sail unit which includes a sail and a sail mast that extends from said decking surface in the upright direction to brace said sail. 
   
   
       12 . The propeller driven surfing device according to  claim 1 , further comprising a stabilizing unit which includes a pair of tail fins that extend from said bottom surface and that are disposed laterally of said water intake port. 
   
   
       13 . The propeller driven surfing device according to  claim 4 , wherein said buoyant body further has a plurality of cooling slits which extend through said bottom surface so as to dissipate heat of said drive motor and said control member.
