发明名称 Plastic tow hitch device
摘要 A flexible and bowed tow hitch having a A-configuration is adapted for trailing a sled behind a snow vehicle. The hitch comprises three plastic straps; two straps form the legs for the A-configuration and the third strap forms the cross-bar for the A-configuration. The ends of the cross-bar strap are physically pressed against the respective ends of the leg straps to form the base terminal of the hitch for attachment to the sled. The other ends of the legs are physically pressed against each other to form the apex for the A-configuration. An elongated bar is embedded between these other ends. The bar is welded to a ring member to form a lunette-type connection for attachment to the snow vehicle.
