摘要： An accessory adapted to be wedged under a traction wheel of a vehicle to allow production of traction upon rotation of that wheel. This anti-slipping accessory is characterized by cleats laterally offset from each other transversely of the accessory to preserve the tractive efficiency even though the supporting surface has been plowed by the cleats; and also, by having a leading end allowing convenient wedging under a roadwheel and gripping of its tire. This accessory includes two converging strips of bendable material, crossbars extending transversely of these strips and simply secured thereto, cleats projecting endwise from one face of these strips and laterally offset from each other transversely of the strips, a crossbar at the leading end adapted to engage notches of the tire of the roadwheel, a crossbar at the trailing end adapted to minimize throwing of the accessory, and advantageous securement of each cleat to both the corresponding crossbar and the corresponding strip.
