Latest Patents
Among his latest inventions is the "Progressively-formed clinch nut." This three-sided, progressively-formed threaded fastener features a plurality of planar longitudinal faces that intersect at corner areas. Shank tabs extend downward from the bottom of each face at the base of the fastener. The threaded regions along the inside surface of the planar faces are created through coined indentations applied during the formation process. Additionally, wedge-shaped protrusions extend downward from the corner areas at the base of the fastener, forming a clinch profile that allows it to be affixed to a sheet of metal by clinch fit.
Another significant patent is the "Threaded insert with flange tabs." This insert for plastic sections is manufactured from a flat strip of metal through high-speed progressive die-stamping. The process forms the strip into a threaded female insert. Initially, the metal strip is cut into a flat blank, and thread regions are impressed on its face, providing a thread pitch profile. During stamping, the strip is folded to create a triangular hollow tube with sharp-edged protrusions extending radially outward from each corner. An interlocking side tab and cutout secure the abutting longitudinal side edges, ensuring axial alignment of the thread regions.
