Lightweight amphibious vehicle

Abstract

A lightweight amphibious vehicle system enables a user to traverse the land or water in the same craft. The wheels have paddles attached on the sides and are powered by a transmission that multiplies the force of a user to enable the system to travel without great effort. The transmission is driven by pedal power input by the user.

Description

BACKGROUND

1. Field of the Invention

The present invention relates generally to recreational vehicle systems, and more specifically, to an amphibious vehicle system for transporting a person over land and water.

2. Description of Related Art

Recreational vehicle systems are well known in the art and are effective means to provide enjoyment by moving a person from one place to another. For example, FIG. 1 depicts a conventional amphibious vehicle system 101 having a hull 103, two axles 105, 107 each with two wheels 109, 111 being rotated by a motor 113 and transmission 115. During use, the vehicle is driven by a user 117 and is configured to run both on land and water.

One of the problems commonly associated with system 101 is limited use. For example, its mobility necessitates a heavy motor reducing the agility of the vehicle in addition to the undesirable noise created by motor.

Accordingly, although great strides have been made in the area of amphibious vehicle systems, many shortcomings remain.

In addition the system of the present application can be powered by the user greatly reducing the noise produced by the vehicle. These and other unique features of the system and method of use are discussed below and illustrated in the accompanying drawings.

The system and method of use will be understood, both as to its structure and operation, from the accompanying drawings, taken in conjunction with the accompanying description. Several embodiments of the system are presented herein. It should be understood that various components, parts, and features of the different embodiments may be combined together and/or interchanged with one another, all of which are within the scope of the present application, even though not all variations and particular embodiments are shown in the drawings. It should also be understood that the mixing and matching of features, elements, and/or functions between various embodiments is expressly contemplated herein so that one of ordinary skill in the art would appreciate from this disclosure that the features, elements, and/or functions of one embodiment may be incorporated into another embodiment as appropriate, unless described otherwise.

The preferred embodiment herein described is not intended to be exhaustive or to limit the invention to the precise form disclosed. It is chosen and described to explain the principles of the invention and its application and practical use to enable others skilled in the art to follow its teachings.

Referring now to the drawings wherein like reference characters identify corresponding or similar elements throughout the several views, FIG. 2 depicts a top view of a lightweight amphibious vehicle system in accordance with a preferred embodiment of the present application. It will be appreciated that system 201 overcomes one or more of the above-listed problems commonly associated with conventional amphibious vehicle systems.

In the contemplated embodiment, system 201 includes a transmission 213 in communication with wheels 207 via axles 211. Each wheel 207 having a paddle 209 attached to the side thereof. The transmission 213 is in communication with a set of pedals 215. The pedals 215 being situated within reach of a user 217 resting in a seat 203. The seat 203 also having a steering device 205 in proximity. The transmission 213 and other parts being housed in a buoyant hull 219.

In use the user 217 rests in the seat 203, and rotates pedals 215 with their legs, this generated force transferred to and maximized by the transmission 213 that causes the wheels 207 and paddles 209 to rotate via axles 211, propelling the system 201 across land or water.

It should be appreciated that one of the unique features believed characteristic of the present application are the paddles 209 and transmission 213 that allow the user 217 to move on both water and land with agility and in near silence. It will also be appreciated that any items common to amphibious vehicles such as oars, lights, cup holder or the like could also be used with system 201 and not deviate from the intent of this disclosure.

While paddles 209 have been depicted it is contemplated that nay means of displacing water with the result of forward motion is contemplated.
