ABSTRACT:
An anti-skid device. The device is installed between tire pairs in vehicles using dual tires in wheel assemblies. The device increases friction between the wheeled vehicle and a slippery surface therebelow. Each of the two or more dual tire type wheel assemblies has a wheel having a central axis of rotation, a first tire, and a second tire. The first and second tire are mounted to the wheel in a spaced apart relationship along the axis of rotation, to provide therebetween a centrally located mounting space which is located radially outward from the central axis of rotation. The anti-skid device is placed in the mounting space between the first tire and the second tire. The anti-skid device includes, in radially outward order, a retainer ring, a spacer ring, an inflation ring (preferably pneumaticaly inflatable), and an anti-skid tread ring. The anti-skid tread ring is displaceable outward by inflation of the inflation ring, so as to engage the slippery surface with tread lugs or studs. The device may be manually, remotely, or automatically activated to inflate and deflate the inflation ring for engagement to or disengagement from a slippery surface therebelow.
