  • Patent number: 12338598
    Abstract: Improved couplers for a building foundation support system include helical ribs and helical grooves in combination with an integrated spring retainer element that automatically snaps into place as the couplers are engaged. Rotational and axial interlocking attachment of support piles is therefore possible without utilizing separately provided fasteners such as bolts.

  • Patent number: 12338599
    Abstract: Coupled shaft assemblies for a foundation support system include shafts provided with profiled distal end edges that may be directly engaged to one another to realize an interlocking torque transmitting relationship with one another along a curved engagement surface. A coupler sleeve may snugly receive the distal ends of the directly engaged shafts and may fasten the shafts to one another through the coupler sleeve with ease in an economical manufacture that does not require non-uniform wall thickness in the shafts to establish torque transmission capability.
