Abstract
A pivotal joint in which a first member having a wheel-shaped end is pivotally connected to a second member having a forked end enveloping the wheel-shaped end and including a primary pivot bolt arrangement extending through the first and second members at the center of the wheel-shaped end to pivotally join the parts, as the primary pivotal connection therebetween and wherein the forked end of the second member presents a circumferential array of three friction surfaces which will cooperate with the periphery of the wheel-shaped end of the first member to pivotally join the two parts as the secondary pivotal connection therebetween if the primary pivot connection fails.
