PROPULSION SYSTEM FOR ASSISTANCE WHEN PADDLING IN SURFING

Abstract

Propulsion system for assistance when paddling in surfing; comprising a propellant device (1), hydro jet type, intended to be mounted on a surfboard (T); and a control device (2) in the manner of a bracelet or bracelet suitable for its attachment on a users arm. The control device (2) comprises: a microprocessor (21), a supply battery (22), sensors (23) that provide the microprocessor (21) with suitable data to identify the users rowing action, calculating the speed and intensity of paddling and generating a control signal proportional to the paddling intensity of the user and; a wireless communication means (24) that transmits the control signal to the propelling device (1); and wherein said propelling device (1) varies the propulsion power as a function of the signals received from the control device (2).

Claims

PREFERRED EMBODIMENT OF THE INVENTION

[0027] The propulsion system for surfing assistance in the surfing practice shown in FIG. 1 comprises a propelling device (1) mounted on a surf board (T) and a control device (2), in the manner of a bracelet, placed on an arm of the user.

[0028] As can be seen in the diagram of FIG. 2 the control device (2), comprises: a microprocessor (21), a power supply battery (22), sensors (23) that provide the microprocessor (21) suitable data to identify the paddling action of the user, calculate the speed and intensity of paddling and generate a control signal proportional to the paddling intensity of the user and; [0029] wireless communication means (24) suitable for transmitting the control signal to the propellant device (1) incorporated in the surfboard (T).

[0030] In the exemplary embodiment shown in FIG. 3, the hydro jet-type propeller device (1) comprises: a propeller or propulsion propeller (11) with the corresponding motor (12), a control unit (13) provided with a wireless receiver (not shown) of the signals from the control device (2) and power batteries (14).

[0031] As mentioned, the function of the control unit (13) is to vary the propulsion power as a function of the signals received from the control device (2), and consequently proportional to the user's padding intensity, providing an assistance to the paddling action.

[0032] In the embodiment shown, the propeller device (1) is integrated into a removable keel (15) provided with standard fastening means (16) for mounting on different surfboards.

[0033] Once the nature of the invention has been sufficiently described, as well as a preferred embodiment, it is stated for the appropriate purposes that the materials, shape, size and arrangement of the described elements may be modified, provided that this does not entail an alteration of the essential features of the invention that are claimed below.
