  • Childproof deadbolt
    Patent number: 8353188
    Abstract: The childproof deadbolt includes a standard deadbolt with a thumb turn wherein a childproofing mechanism is integrated into the design of the thumb turn. The childproofing mechanism consists of at least one spring-loaded push button that when depressed engages an internal gear in rotational connection with the deadbolt. Absent depression of said push button the thumb turn is free to rotate independent of the internal gear and the deadbolt.
