Abstract: The pivotal joint has a member(12) with a wheel-shaped end(18) pivoted to a second member(14) having a forked end(22) enveloping the wheel end(18). It includes a primary pivot bolt arrangement(30) extending through the members at the center of the wheel end(18) to pivotally join the parts. The forked end presents a circumferential array of three friction surfaces (24, 26, 28) which will cooperate with the periphery (20) of the wheel end to pivotally join the two parts(12, 14) as a secondary pivotal connection between them if the first pivot connection fails.

Abstract: A pivotal joint in which a first member (10) having a wheel-shaped end (18) is pivotally connected to a second member (12) having a forked end (22) enveloping the wheel-shaped end and including a primary pivot bolt (30) 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 (24, 26, 28) which will cooperate with the periphery (20) 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.
