Abstract
A locking doorknob shroud, configured to be placed over a doorknob, padlock, or similar closing mechanism. The shroud is equipped with two halves which interlock together and seal firmly with a latch. A keyhole, present at a junction of the two halves within the latch, is configured to accept a key, which when turns, unlocks the latch. Alternately, or in addition, a padlock may be used to further secure the latch. A spring assembly disposed in communication with at least one hinge enables the two halves to open about the at least one hinge, providing access to the doorknob when permitted.
