Implement Frame Tube Joint with Weldable Connector

An agricultural implement frame comprising:

• a first frame tube;
• a second frame tube;
• the first and second frame tubes having side walls connected by upper and lower walls;
• a weldable connector having a first receiving area opening towards the first frame tube and conforming to the shape of the first frame tube, the connector including an a second receiving area opening towards the second frame tube conforming to the shape of the second frame tube;
• first weld structure connecting at least one of the walls of the first frame tube to the connector adjacent the first receiving area;
• second weld structure connecting a central portion of the side walls of the second frame tube to the casting adjacent the upwardly opening receiving area;
• and
• wherein the first frame tube and the second frame tube lie generally in the same plane, and the weldable connector is secured to an end of the second frame tube and locates the end relative to the first frame tube.

An agricultural implement frame comprising:

• a second frame tube;
• the first and second frame tubes having side walls connected by upper and lower walls;
• a weldable connector having a first receiving area opening towards the first frame tube and conforming to the shape of the first frame tube, the connector including an a second receiving area opening towards the second frame tube conforming to the shape of the second frame tube;
• first weld structure connecting at least one of the walls of the first frame tube to the connector adjacent the first receiving area;
• second weld structure connecting a central portion of the side walls of the second frame tube to the casting adjacent the upwardly opening receiving area;
• and
• wherein the connector includes an outwardly extending flange abutting one of the walls of the first frame tube at a location on the wall offset inwardly from corners of the first frame tube, wherein the flange includes an extension edge offset outwardly from the second frame tube, and a weld connecting the extension edge to said one of the walls of the first frame tube and providing connector mechanical advantage to resist frame parallogramming.

An agricultural implement frame comprising:

• a lower frame tube;
• an upper frame tube;
• the upper and lower frame tubes having upright sidewalls connected by upper and lower walls;
• a weldable connector having a downwardly opening receiving area conforming to the shape of the lower tube, the weldable connector including an upwardly opening receiving area conforming to the shape of the upper tube;
• first weld structure connecting the top of the lower frame tube to the weldable connector adjacent the downwardly opening receiving areas;
• second weld structure connecting the upright sidewalls of the upper frame tube to the weldable connector adjacent the upwardly opening receiving area;
• and
• a side weld connecting the sidewalls of the lower frame tube to the weldable connector adjacent the downwardly opening receiving area;
• and
• wherein the connector includes an outwardly directed flange with an outer edge abutting the top of the first tube, and wherein the first weld structure includes a weld connecting the outer edge to the top of the first frame tube at a location outwardly of the second frame tube and providing resistance to parallelogramming.

An agricultural implement frame comprising:

• a first frame tube;
• a second frame tube;
• the first and second frame tubes having side walls connected tube corners by upper and lower walls;
• a weldable connector having a first receiving area opening towards the first frame tube and conforming to the shape of the first frame tube, the connector including an a second receiving area opening towards the second frame tube conforming to the shape of the second frame tube;
• first weld structure connecting at least one of the walls of the first frame tube to the connector adjacent the first receiving area;
• second weld structure connecting a central portion of the side walls of the second frame tube to the casting adjacent the upwardly opening receiving area;
• wherein the first frame tube and the second frame tube lie generally in the same plane, and the weldable connector is secured to an end of the second frame tube and locates the end relative to the first frame tube;
• and
• wherein the first weld structure is centrally located between the tube corners and offset from the tube corners.
