Abstract
The invention provides a vehicle frame joint structure that is used in a ladder frame structure and in space frame type structures. The joint includes at least a first member, a second member, and a third member extending thereinbetween. Each of these three members has an upper surface, a lower surface, and opposed side walls. The third member, which is adapted to extend thereinbetween has an upper surface that extends beyond its opposed side walls and lower surface. Each of the first and second members has therein a relief adapted to receive the third member such that the third member's extending upper surface is in close relationship with the first and second members' upper surface. Also, the third members' side surfaces proximate the extending upper surfaces at each end thereof are in close relationship with the opposed side walls of each of the first and second members.
