  • a conventional propeller driven surfing device is shown to include a float board 11, a propeller unit 12 disposed on the surfboard 11, and a control handle 13 coupled to the propeller unit 12.
  • the surfboard 11 has front and back edges 111, 112, and top and bottom surfaces 113,114 interconnecting the front and back edges 111,112.
  • the propeller unit 12 is connected to the back edge 112 by a dovetailed joint 122 and is operable to generate a driving force to propel the surfboard 11 forward.
  • the propeller unit 12 includes a body 121, a drive motor (not shown) which is disposed in the body 121 and which has an output shaft 124 extending rearwardly, and a propeller 125 which is coupled to the output shaft 124 and which is covered with a meshed guard.
  • the control handle 13 includes a handlebar 131 connected to and extending from the propeller unit 12, and a handgrip 132 attached to an upper end of the handlebar 131 to be used for steadying the user and for actuating the drive motor.
  • the object of the present invention is to provide a propeller driven surfing device which can achieve a great driving force for forward propulsion.
  • Another object of the present invention is to provide a propeller driven surfing device which allows the user to perform surfing with a greater flexibility and freedom.
  • the propeller driven surfing device includes an elongated body, a drive unit, a shell member, and an operating unit.
  • the elongated body has front and rear ends opposite to each other along a longitudinal axis, and a tubular wall extending to interconnect the front and rear ends so as to define an accommodation chamber therein.
  • the drive unit includes a drive motor, a power supply, and a control member disposed in the accommodation chamber.
  • the control member is electrically coupled to the drive motor and the power supply.
  • a propeller is driven by the drive motor, and is disposed outwardly of the elongated body and rearwardly of the rear end.
  • the shell member includes a front surrounding segment which surrounds and which is spaced apart from the tubular wall to define a passageway therebetween, and a rear surrounding segment which extends rearwardly from the front surrounding segment and which terminates at a distal end that is disposed rearwardly of the propeller.
  • the front surrounding segment and the distal end respectively define a water intake port and a water outlet port which are disposed upstream and downstream of the passageway, respectively, such that water flows from the intake port and out of the outlet port through the passageway.
  • the operating unit is electrically coupled to the control member, and is disposed to be movable relative to the shell member so as to be operable to control operation of the control member.
  • the first preferred embodiment of a propeller driven surfing device is shown to comprise an elongated body 20, a drive unit 30, a shell member 40, and an operating unit 50.
  • the elongated body 20 is torpedo-shaped, and has front and rear ends 2 01,202 opposite to each other along a longitudinal axis, and a tubular wall 203 extending in a longitudinal direction parallel to the longitudinal axis to interconnect the front and rear ends 201,202 so as to define an accommodation chamber 2 04 therein.
  • the drive unit 30 includes a control member 31, such as a control module which is disposed in the accommodation chamber 204, a power supply 32, such as a battery, which is disposed in the accommodation chamber 204 and which is electrically coupled to the control member 31, a drive motor 33 which is disposed in the accommodation chamber 5 2 04 and which is electrically coupled to the control member 31, and a propeller 34 which is driven by the drive motor 33 and which is disposed outwardly of the elongated body 20 and rearwardly of the rear end 202.
  • a control member 31 such as a control module which is disposed in the accommodation chamber 204
  • a power supply 32 such as a battery
  • a drive motor 33 which is disposed in the accommodation chamber 5 2 04 and which is electrically coupled to the control member 31
  • a propeller 34 which is driven by the drive motor 33 and which is disposed outwardly of the elongated body 20 and rearwardly of the rear end 202.
  • the shell member 4 0 includes a front surrounding segment 10 401 which surrounds and which is spaced apart from the tubular wall 203 to define a passageway 43 therebetween, and a rear surrounding segment 402 which extends rearwardly from the front surrounding segment 401 in the longitudinal direction and which terminates at a distal end 403 that is disposed rearwardly of the propeller 34 and that is spaced apart from the propeller 34 in the longitudinal direction.
  • the rear surrounding segment 402 is configured to converge towards the longitudinal axis from the front surrounding segment 401 to the distal end 403.
  • the front 20 surrounding segment 401 defines a water intake port 42 having a pair of intake port portions 421 which are disposed opposite to each other in a diametrical direction relative to the longitudinal axis and which are disposed upstream of the passageway 43 such that water entering the passageway 43 through the two intake port portions 421 during operation of the propeller 34 forms two water currents in the passageway 43.
  • the distal end 403 defines a water outlet port 41 which is disposed downstream of the passageway 43.
  • the two water currents in the passageway 43 will meet before reaching the propeller 34 and will flow out of the outlet port 41 as one column of water.
  • the front surrounding segment 401 has a pair of positioning sockets 44 which are disposed diametrically opposite to each other.
  • the operating unit 50 includes a pair of handgrips 51, each of which has a plug 511 that is configured to be 10 detachably fitted into a respective one of the positioning sockets 44 in a mortise-and-tenon engagement using, for instance, a dovetail structure, and a control button 52 which is mounted on one of the handgrips 51 and which is electrically coupled to the control member 31 by means of a signal cable 53.
  • the operating unit 50 is movable and operable by the user to control operation of the control member 31 so as to shift the drive of the drive motor 33, such as the rotational speed thereof.
  • the shell member 40 and the fully opened outlet port 41 water flow is not thwarted by any interfering objects so that the drive force generated as a result of action of the propeller 34 can be fully utilized to propel the surfing device forward.
  • the handgrip 51 having the control button 52 mounted thereon is detachable from the positioning socket 44, the user can operate the control button 52 to control the propeller 34 in any posture, thereby affording the user with greater flexibility and freedom when performing a water activity.
  • the second preferred embodiment of a propeller driven surfing device is shown to be similar to that of the aforesaid embodiment in construction.
  • This embodiment further includes a pair of shoulder straps 61 which are detachably mounted on the positioning sockets 44 of the front surrounding segment 4 01 of the shell member 40, and a waist strap 62 which is detachably mounted on the rear surrounding segment 402 of the shell member 40 by means of dovetail joints, thereby facilitating carrying of the surfing device.
  • the third preferred embodiment of a propeller driven surfing device is shown to be similar to that of the first preferred embodiment in construction.
  • This embodiment further includes a surfboard 70 which has a bottom surface 7 01.
  • the shell member 4 0 is detachably coupled to the bottom surface 701 in a mortise-and-tenon engagement by way of a dovetail joint, for instance.
  • the user can stand on the surfboard 7 0 and grip the handgrip 51 to operate the control button 52.
  • the drive unit 30 and the shell member 40 are disposed at a middle position of the surfboard 5 70 where the center of gravity of the surfing device is located, the user can practice surfing with greater flexibility as if using a conventional surfboard.
  • the fourth preferred embodiment of a propeller driven surfing device according 10 to this invention is shown to be similar to the third preferred embodiment in construction.
  • the control member 31 includes a wireless communication module which is disposed to control the drive motor 33 in response to a signal emitted from the operating unit 15 50 in a known manner, thereby dispensing with the signal cable 53.
