ABSTRACT:
The present invention provides a new and improved portable door lock that can be used in conjunction with a door, a door jamb and a striker plate. The portable door lock comprises a bolt having a first end, a second end and an intermediate extent therebetween. A cylindrical threaded portion comprises the first end of the bolt. The cylindrical threaded portion has an outer diameter defined by the threads. A flat portion comprises the second end of the bolt. The flat portion has a width and a thickness which allows it to extend between a door and a door jamb. A hook portion extends from and is integral with the second end of the bolt. The hook has a top surface and a bottom surface. The hook is adapted to be engaged around the striker plate of a door jamb. A securing fitting is employed by the lock. The fitting has a hollow cylindrical first end and a first side and a second side, and a flat plate at the second end. The flat plate extends 90 degrees relative to, and at one side of, the cylindrical first end. The cylindrical first end has an internal diameter which is larger than the outer diameter of the threaded portion of the bolt. The metal securing fitting is positioned over the cylindrical threaded portion of the bolt. A wing nut is employed in securing the overall lock. The nut has two finger-engaging portions and an internal threaded aperture. The internal threaded aperture of the wing nut is adapted to be secured over the threaded cylindrical portion of the bolt.
