Tube Joint in Implement Frame

摘要

An agricultural implement frame has a beam with a pair of tube members joined by a tube joint. The tube joint has an overlaying portion formed by overlaying ends of the first and second tube members, each overlaying end having an overlaying wall and a base wall connected by opposing side walls. The side walls have interface surfaces extending from a lip at one end of the overlaying wall to a foot in the base wall such that when the tube members are joined together, the interface surfaces contact and the lip of the first tube member abuts the foot of the second tube member and the lip of the second tube member abuts the foot of the first tube member. A fastener clamps together the overlaying ends of the tube members and interlocking load transfer teeth in the interface surfaces transfer load between the tube members.
