  • Leaf spring lock cylinder
    Patent number: 9512638
    Abstract: A lock cylinder generally including a shell, a plug positioned within the shell, a locking member, and a leaf spring. The plug includes an opening which is aligned with a recess formed in the shell. The locking member is configured to selectively prevent rotation of the plug with respect to the shell. The leaf spring is positioned in the opening and includes a first portion extending radially inward toward the keyway, and a second portion extending radially outward toward the recess. When a key is inserted, a tip of the second portion extends into the recess. When the plug is subsequently rotated, a tapered surface of the recess urges the tip radially inward and into contact with an inner surface of the shell.
