ABSTRACT:
A lockable doorknob enclosure for use on doorknobs of the type having a knob attached to a shaft having a longitudinal axis. The lockable doorknob enclosure comprises: a containment structure having a sealable cavity for enclosing the doorknob and a portion of the shaft; an adjustable spacing mechanism; and a locking mechanism. The containment structure includes first and second pivoting structures which are preferably connected by a hinge. The first and second pivoting structures form a containment cavity of a size sufficient to receive therein the doorknob and a portion of the shaft when the pivoting structures are pivoted into a first, or closed, position. The containment structure has an aperture therethrough of dimensions sufficient to allow the shaft to be installed through the aperture when the first and second pivoting structures are pivoted into a second, or open, position. The adjustable spacing mechanism is located within the containment cavity and is positionable between the door knob and the aperture in a manner such that movement of the doorknob is restricted in a direction along the longitudinal axis of the shaft. An exterior portion of at least one of the first and second pivoting structures preferably includes a padded surface extending therefrom.
