Benefits of technology

The design provides increased propulsion force and user flexibility by optimizing water flow and allowing operation from various postures, enhancing the surfing experience by distributing weight evenly and eliminating flow obstruction.

Problems solved by technology

However, the user has to hold the device 100 with both hands, which is inconvenient.
Although this propeller driven surfing device allows a person with little surfboard riding skill to operate in relatively calm water, the following drawbacks arise:
Thus, the surf riding routines is difficult to perform.
Besides, the meshed guard covering the propeller 125 may thwart the flow of the water, thereby further weakening the propelling force of the water.

Embodiment Construction

[0029] Before the present invention is described in greater detail, it should be noted that same reference numerals have been used to denote like elements throughout the specification.

[0030] Referring to FIGS. 6 to 8, the first preferred embodiment of a propeller driven surfing device according to the present invention is shown to comprise an elongated body 20, a drive unit 30, a shell member 40, and an operating unit 50.

[0031] The elongated body 20 is torpedo-shaped, and has front and rear ends 201, 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 204 therein.

[0032] 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 ele...

Abstract

A propeller driven surfing device includes an elongated body defining an accommodation chamber for receiving a drive motor and a power supply therein. A propeller is driven by the drive motor, and is disposed outwardly and rearwardly of the elongated body. A shell member includes a front surrounding segment which surrounds and which is spaced apart from the elongated body to define a passageway therebetween, and a rear surrounding segment which extends rearwardly to terminate 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.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims priority of Taiwanese Application No. 094136886, filed on Oct. 21, 2005. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] This invention relates to a surfing device, more particularly to a propeller driven surfing device driven by a motor for propelling through water. [0004] 2. Description of the Related Art [0005] Referring to FIGS. 1 and 2, a conventional water propeller device 100 can be used in a diving activity (as shown in FIG. 1), and can be connected to a float board 101 for use in swimming (as shown in FIG. 2). However, the user has to hold the device 100 with both hands, which is inconvenient. [0006] Referring to FIGS. 3 and 4, 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 botto...
