发明名称 Device for childproofing a door lock
摘要 The device for childproofing a door lock is a device that fits on a standard lockset and prevents a lever or doorknob from turning when the device is engaged. The childproof door lock includes a substantially rectangular base plate and a circular disk that mounts atop the base. A sliding plate mounted on the base has a cylindrical locking post that engages a notch on the circular disk and prevents it from turning. The sliding plate may be spring-biased to hold the locking post in the notch. A lever may be attached to the sliding plate to disengage the locking post from the notch and allow the circular disk to turn freely.
