ABSTRACT:
Device and method utilizing a fixed assembly attachable to a vehicle wheel back support plate, and a journaled, rotatable assembly carrying a track which may be deployed to engage and rotate with the wheel, or retracted for stable storage. The track is supported by leading and trailing arms carried on the rotatable assembly of the device, which arms in turn are movable concentrically to the device journal to expand the track around the tire and move inwardly upon completion of the track expansion to encircle the tire. Tracks utilizing linkages and rigid traction bars, or resilient members may be employed. Deployment and retraction power may be manual or provided by springs preloadable utilizing the rotational energy of the wheel, by fluid means, i.e. hydraulic vacuum and pneumatic, or by electric power, with the deployment and retraction being powered by a common means, or with the two movements or portions thereof being powered by a combination of power means.
