  • Patent number: 5002251
    Abstract: A hold down assembly for removable vehicle accessories comprises a rigid friction rod, which depends from the accessory, and a retaining assembly, which consists of a retaining disc, a spring, a spring base disc, an actuator cable, and a cable ferrule. In the operation of the holding assembly, the rigid friction rod is inserted into the retaining assembly and enters an aperture of the retaining disc which guides and directs the rod end through the center of the spring and into an aperture of the spring base disc. The pulling force exerted on the actuator cable causes the ferrule to exert a downward eccentric pressure on the retaining disc. When subjected to such off-center pressure, the retaining disc is pulled down in a tilted fashion causing an engaging edge of the retaining disc to bite into the rigid friction rod.
