  • Structural weld joint with internal gusset
    Patent number: 5630622
    Abstract: This invention utilizes a cast corner member (20) as a support base for the load bearing members (14) of a roll over protection structure (10). The cast corner member (20) has an end portion (34) comprising at least one gusset (40) which telescopically engages a tubular member (14). The gusset (40) has a tapered configuration which defines a free end portion (36) that has a reduced cross-sectional area and is positioned within the tubular member (14) in slightly spaced relationship to at least one of the side walls of the tubular member (14). When the end portion (34) of the corner member (20) is telescopically received within the tubular member (14), a groove is formed to receive a weld bead (22) which secures the two members together.
