  • Door handle set having a supplemental child-resistant lock
    Patent number: 11668116
    Abstract: A door handle set includes a handle assembly having a primary lock and having a handle rotatable about a primary rotational axis. A latch bolt assembly has a latch bolt. The latch bolt assembly is operatively coupled to the handle assembly, wherein a rotation of the handle results in a linear translation of the latch bolt. A supplemental lock has a second axis parallel to, and spaced apart from, the primary rotational axis. The supplemental lock has an actuator that is operable relative to the second axis. The supplemental lock is configured to selectively block the rotation of the handle regardless of the locking state of the primary lock.
