Abstract
A device for temporarily disabling a doorknob attached to a hinged door. The device covers the doorknob with a rigid enclosure, preventing rotation of the doorknob to move the associated locking bolt. A retaining unit is mated with an extension from the rigid enclosure in a male-female relationship, simultaneously with fitting the retaining unit over the outer edge of the hinged door while ajar. Closure of the door into the associated doorjamb, with the enclosure over the doorknob, prevents parting movement between the enclosure and the retaining unit, providing a self-locking feature.
Claims20
A doorknob disabling device for utilization on a doorknob affixed to a hinged door, comprising:
- a rigid enclosure means, truncated to provide an opening, substantially in a singular plane, conformed to fit over and enclose a doorknob with said opening substantially flush to a supporting door;
- a retention means, conformed to removably engage an ajar door edge and further conformed to define an aperture in the portion thereof which contacts the outer end of the surface of the door, of sufficient dimension to allow passage of a locking bolt which is irremovable when said door is closed;
- and
- a mating means wherein said enclosure means and retention means are rigidly mated by sequential placement of the enclosure means and the retention means.
A doorknob disabling device for utilization on a doorknob affixed to a hinged door, comprising:
- a rigid enclosure means, truncated to provide an opening, substantially in a singular plane, conformed to fit over and enclose a doorknob with said opening substantially flush to a supporting door;
- a retention means, comprising a plurality of angularly conformed planar sections conformed to simultaneously substantially contact the front, back and outer end surfaces of a supporting door, which is irremovable when said door is closed;
- and
- a mating means wherein said enclosure means and retention means are rigidly mated by sequential placement of the enclosure means and the retention means.
A doorknob disabling device for utilization on a doorknob affixed to a hinged door, comprising:
- a hollow enclosure member having a unitary rigid outer surface and a unitary inner surface;
- said hollow enclosure member being truncated so as to define an opening in said outer surface and inner surface in a single plane;
- a rigid first mating member having a length, height and width dimension, a first end affixed to said enclosure member, and a second extending outwardly therefrom in parallel with the plane of said opening;
- a retention member comprised of two opposing parallel planar side members each having an outer surface and an inner surface defining a uniform width between them, an open top, open bottom, open end and a closed end;
- said closed end of said retention member being further conformed to define an aperture therein of sufficient dimension to allow passage of a locking bolt;
- said side members being joined at said closed end by a planar end member extending between them in a perpendicular plane;
- a second mating member attached to said retention member on the outer surface of one of the side members;
- and
- a coupling means, wherein said first mating member is rigidly coupled with said second mating member in male-female relationship by movement of the open end of said retention member toward the second end of said first mating member with the plane of said open end of said retention member being perpendicular to the length of said first mating member.
