A portable door security mechanism which allows an existing door to be temporarily secured from the non-hinged side of the door without destruction or penetration of the door, the door frame or any existing components of the door, is disclosed. The device uses a cylindrical locking pin which is designed to slip underneath the door to be secured and rotated such that part of the locking pin protrudes upward to prevent the door from opening from the inside. The locking pin is secured to a base plate member and a cover plate which, when interlocked over a portion of the locking pin, is disposed to accept a conventional pad lock or similar device. The disclosed security mechanism can be folded through a hinge mechanism for convenience and can be applied or removed quickly without having access to the interior side of the door.
A locking bracket for securing a hinged door from the non-hinged side of such door, wherein said door is comprised of a door panel attached to a door frame through at least one hinge which allows the said door panel to open through said door frame comprising:
A locking bracket for securing a door from the non-hinged side of said door, where said door uses hinges which attach said door to a door frame, said locking bracket comprising a substantially flat base member having at least one opening to receive a head portion of a locking pin;
A locking device for securing a door to a door frame supporting the door by hinges, the said door being of the type having an outer side and an inner side on the hinged side of said door, the locking device comprising;
A locking device for securing a door to a door frame pivotally supporting the door for swinging movement between a closed position and an open position, and said door being of the type having a space between the hinged and non-hinged side of the door and located at the bottom of said door, the locking device comprising;
A locking device for securing a door to a door frame pivotally supporting the door, the door frame being of the type having members which border the door attached to the frame, and the intended door being of the type having a space between the door surfaces which comprise a hinged and a non-hinged side of said door, the locking device comprising a first plate containing at least one opening and projecting between at least two opposite edges of the door frame in position to engage members of the door frame;
