Abstract
The present doorlock closure secures existing doors having conventional doorknobs against entry by enveloping the doorknob with opposed cavity compartments of knob confining segments. Upper and lower housing segments are hinged together such that they may mount elements which form a cam-lever, segment interlocking assembly. The assembly includes a spring-loaded latch and lockable latch lever in the upper segment and a corresponding cam latch release in the lower segment. The housing segments themselves are hinged together for facile clamping upon the doorknob of a door, securing it against entry by persons having a passkey to the doorknob which retains a turnkey lock therein.
