International ClassB60B 039/12AbstractThe present invention provides a ground cover mat that protects the terrain from a vehicle or the like. The ground cover mat is manufactured by molding recycled polyethylene plastic into a sheet-like mat, which is inexpensive, relatively light in weight, durable in harsh conditions and easy to cut. The ground cover mat includes a pattern of lugs on its upper and lower surfaces to provide a traction surface for the vehicle and to provide friction between the terrain and the ground cover mat.Field of SearchAnti-slip surfacePortable mat type Foraminous traffic surface Composite or compound Including variation in thickness Thickness (relative or absolute) Textured (e.g., pitted, cratered, drilled, etc) Symmetrical pattern or pattern unit (28) Three or more repeats, or uniform configuration, about axis Consisting entirely of material having uniform thickness Traction mats SPECIFIED WEAR OR FRICTION-TYPE TRAFFIC-CARRYING SURFACE | |
