Corner-connected Sections Patents (Class 152/183)
  • Patent number: 5556487
    Abstract: A track device for mounting on a pneumatic tire fitted to the wheel of a vehicle to improve the buoyancy and traction of the vehicle over very soft terrain, the pneumatic tire including a tread surface across the width of the tire, a pair of side walls and an axis of rotation. The track device includes a plurality of bridge-like longitudinal and rigid traction blades having an inside surface made to rest on the tire across the width of the tread surface and a ground engaging outside surface, the traction blades being disposed on the tire in generally closely spaced-apart and parallel relationship to form an endless track. Each traction blade includes an intermediate bridge-like portion made to conform to the general cross-sectional shape of the tire, essentially flat side portions outwardly projecting from either side of the intermediate portion and generally parallel to the axis of rotation of the tire.
