TODAY’S PATENT – GRID RUNNER CAP ANCHORING LANCE

The Grid Runner Cap Anchoring Lance was invented by James J. Lehane, Jr. (McHenry, IL), Steven E. Farley (Wellington, OH), Donald J. Leahy (North Olmsted, OH), Ronald J. Koval (Aurora, IL), Paul A. Pomeroy (Spencer, OH) on the 26^th of November, 2013, and bearing patent number US8590160B2.

The invention overcomes a problem that can occur in the manufacture of roll-formed multi-strip grid runners. Such runners may have a tendency to develop different lengths of the strips when they are subjected to roll forming. The invention provides a technique for locking the strips of a multiple strip grid runner together to enable the strips to be successfully roll-formed without a change in length of one of the strips relative to the other. In various types of grid runner profiles, it can be necessary or desirable to trim the component strips to length after they have been initially rolled together into a pre-form.
