Abstract
An apparatus for adding a propulsion wheel to a land based vehicle. When the apparatus is attached to a land based vehicle the apparatus is operationally configured to bias a propulsion wheel attached thereto to a position of engagement with a travel surface supporting the land based vehicle thereon.
Claims13
An apparatus for adding a propulsion wheel to a land based vehicle effective to move across a travel surface, when attached to the land based vehicle the apparatus is operationally configured to bias a propulsion wheel attached to the apparatus in an engagement position with the travel surface, wherein the apparatus includes a first part operationally configured to attach to the land based vehicle, a second part operationally configured to receive a propulsion wheel in attachment thereto, the second part being pivotally attached to the first part and a biasing member in communication with the second part, wherein the biasing member is a worm gear screw jack.
An apparatus for adding a propulsion wheel to a land based vehicle effective to move across a travel surface, when attached to the land based vehicle the apparatus is operationally configured to bias a propulsion wheel attached to the apparatus in an engagement position with the travel surface, wherein the apparatus includes a first part operationally configured to attach to the land based vehicle and a second part operationally configured to receive a propulsion wheel in attachment thereto, wherein the second part is a wheel stay pivotally attached to the first part.
A method of biasing a propulsion wheel against a travel surface of a land based vehicle, the method comprising the following steps:
- attaching to a land based vehicle an apparatus and propulsion wheel rotatably attached thereto, the apparatus having a first part operationally configured to attach to the land based vehicle, a second part in the form of a wheel stay operationally configured to receive a propulsion wheel in attachment thereto and a biasing member in communication with the wheel stay for pivoting the wheel stay about the land based vehicle in a manner effective to direct the propulsion wheel between one or more engagement positions and one or more disengagement positions with the travel surface;
- and
- directing the propulsion wheel to a first biased position against the travel surface.
