ABSTRACT:
An anti-skid device for ready application to a vehicle wheel, that is entirely installable from the outer or hub side of the wheel. A primary embodiment of my device comprises at least three curved cleats, each having an inner surface and an outer surface, and each also having an integral attachment flange having a deliberate bend therein. Each cleat is configured and designed to curve in a cantilever manner around the tread of the tire, and in a primary embodiment, the cleats are interconnected by a number of elongate connection rods. The elongate assembly so formed can be placed around a tire, to encompass substantially more than half of the periphery of the wheel when the cleats are arrayed in an approximately equally spaced relation in contact with the tread of the tire, with the inner surface of each cleat normally disposed in a stand-away relation to the tread of the tire. When the assembly has been tightened around the tire, to place it in its operational mode, the inner surface of each of the cleats is caused to depart from the stand-away relation to the tire tread, and to move into tight contact with the tire tread, thereby creating a form of spring that serves to eliminate any slack tending to form in the assembly due to the tire deforming as a consequence of rolling contact with the ground.
