  • Patent number: 6173593
    Abstract: An improved locking mechanism and method for securing drawers and cabinet doors is disclosed which allows the drawers and cabinet doors to be only partially opened until the locking mechanism is unlocked. When the drawer or cabinet door is closed, the hidden locking mechanism of the present invention is entirely concealed from view behind the drawer or cabinet door. The locking mechanism of the present invention allows the drawer or cabinet door to be opened sufficiently to expose the locking mechanism, but effectively prevents the drawer or cabinet door from being more than slightly opened until the locking mechanism is unlocked. When the locking mechanism is unlocked, the drawer or cabinet door may then be fully opened.
