AI Technical Summary

Benefits of technology

"The invention is an aquatic device that can be easily controlled and maneuvered through water. It has two control elements that move relative to each other, allowing the user to control the direction of the device. The control elements have protrusions that guide water flow and prevent water from spilling sideways. The device can be towed through water or propelled by the user. The handle means are connected to the control elements, allowing the user to control their movement. The device can be fitted with a tow line for added propulsion. The technical effects of the invention include improved control and maneuverability of the aquatic device."

Problems solved by technology

While articulation of the planar member does provide some steering and depth control, there can be a significant lag between articulation of the planar member and a resultant directional change in the movement of the user.
Accordingly, there can be a lack of responsiveness and subtle changes in direction can be difficult to achieve.
Such an aquatic device offers limited direction control through tilting of the board and is generally not suitable for use underwater.

Embodiment Construction

[0065]Referring to FIGS. 1 to 12 of the drawings, there is shown an aquatic device 10 according to the first embodiment for towing a user 11 through a body of water 13. The aquatic device 10 is adapted to be towed behind a boat 15 by way of a tow line 17, and the user 11 may travel on or under the water.

[0066]The aquatic device 10 comprises handle means 20 adapted to be grasped by the user 11 with arms extending forwardly, and two fins 21, 22 pivotally moveable with respect to each other.

[0067]The aquatic device 10 further comprises an axle 23 onto which the handle means 20 and the fins 21, 22 are pivotally mounted. In the arrangement shown the axle 23 is tubular, comprising a rigid tube of any appropriate material such as aluminium.

[0068]The handle means 20 comprises two handles 24 each connected to a respective one of the fins 21, 22. With this arrangement, the combination of each handle 24 and its respective fin 21, 22 comprises a control unit 25. The control units are rotatably ...

Abstract

An aquatic device (10) for providing maneuverability to a user (11) moving in water. The aquatic device (10) may be propelled through the water in any appropriate way, such as by being towed through the water or propelled through the water by the user (11). The aquatic device (10) comprises a handle means (20) adapted to be grasped by the user (11) with arms extending forwardly, and two fins (21, 22) movable one with respect of one to the other to manoeuvre the aquatic device. The aquatic device (10) can be maneuvered through movement of the fins (21, 22) to provide directional control or variation to the orientation of the aquatic device. The directional control may include both steering and depth control. The handle means (20) are operably connected to the two fins (21, 22) whereby the user can manually control movement of the fins one with respect to the other.

Description

[0001]This application is a Continuation of U.S. Ser. No. 12 / 144,393, filed 23 Jun. 2008, which is a Continuation-in-Part of PCT / AU2006 / 001862, filed 7 Dec. 2006, which claims benefit of Serial No. 2005907264, filed 23 Dec. 2005 in Australia and which applications are incorporated herein by reference. To the extent appropriate, a claim of priority is made to each of the above disclosed applications.FIELD OF THE INVENTION[0002]This invention relates to an aquatic device, and more particularly to an aquatic device for providing maneuverability to a user moving in water.BACKGROUND OF THE INVENTION[0003]There have been various proposals for maneuvering a person through a body of water. The proposals typically involve devices for propelling a user through a body of water in a manner which allows the user to travel either along the water surface or under water. Such devices have recreational applications and are also particularly suitable for underwater pursuits such as diving and snorkel...
