Abstract (en)
[origin: US5797287A] A key has a flat key body having a blade extending along a longitudinal insert axis and having a front edge formed with transversely directed bitting, an opposite longitudinally extending back edge, and a pair of oppositely directed faces. Each face is formed with at least two longitudinally extending front grooves extending adjacent the front edge a full length of the blade and having depths equal to more than half of a transverse thickness of the blade, a longitudinally extending back groove having a floor at a depth equal to less than half of the blade thickness, and an elongated angled groove extending at an acute angle to and across the respective back groove at an intersection and having a part-cylindrical floor aligned with and forming a smooth continuation of the floor of the respective back groove at the intersection. The angled groove of the one face extends nonparallel to the angled groove of the other face, that is axes of the angled grooves on one face are all parallel to each other and cross similar axes of the grooves on the other face.
