Abstract: The modular tire chain apparatus provides for ease of installation due to connecting modules that allow a user to assemble the apparatus on a tire and wheel with greater ease than having to struggle with a continuous tire chain. A further advantage of the modules is that any number of modules needed to surround a tire and wheel are easily attached together, thereby providing a substantially universal fit to a plethora of tire sizes. And, the tie strap with spring with hook aids in securing the modules to a tire. Further the ties are secured, one to the other and to the outer members. The ratchet lock further ensures snug fit of the apparatus. The inner cable, outer cable, inner members, outer members, and cross members are available in rubber coated finish, thereby avoiding potential vehicle and wheel and tire damage.

Abstract: A traction device, preferably formed of an elastomer material, has molded threads and is designed to encapsulate a tire of a vehicle. The traction device has a body with a pair of distal ends. At one of the ends a pair of metal hooks are pivotally mounted to a hinge pin. When the traction device is placed around the tire, the metal hooks engage a locking pin disposed on the other end of the body. A bladder is mounted to an inner surface of the body such that the bladder becomes sandwiched between the body and the tire. Tension and grip is applied to the traction device by inflating the bladder. Air is introduced via an air valve through a communication duct. Once mounted, the traction device essentially becomes an integral member of the vehicle tire, thereby enhancing the traction of the drive wheels.

The sealing member is under compression and has a surface of highly compressible material to conform to irregularities in the track assembly for sealing the space between the traction shoes and the belt. The sealing member may be of rubber or plastic foam so that during compression and decompression the space occupied by the sealing member may decrease and increase while the sealing member maintains a sealing relationship with the traction shoes and belt. The sealing member may also be adhered to the belt-engaging surface of a traction shoe or to the belt. Further, the sealing member may be positioned between adjacent traction shoes with overhanging ribs of the shoes engaging the transverse edges of the sealing member to hold it in position and compress the edges.
