Skidproof traction mat for automotive vehicles
Abstract:
A traction pad for an automotive vehicle having pneumatic tires, that comprises a flat, flexible mat formed with transverse treads on its upper surface. Studs embedded in the mat extend out of the smooth bottom surface of the mat for engagement with a slippery roadway. The mat is rectangular and has long beveled side and end edges to provide an incline on which the wheel can roll. Each stud has a cylindrical body with a reduced diameter cylindrical pin portion extending outwardly axially of one end thereof. Ridges are provided on the bottom surface between rows of protruding stud pin portions to cooperate with the studs in holding the mat in place on the roadway. The ridges elevate the pin portions from the carpet on the floor of the vehicle when the pad is stored thereover and being used as mat thereupon. Draglines may be attached to an end of the mat.
