Abstract
A portable door lock comprises a planar lock plate for extending from a door frame and a door edge with a transverse tongue at one end that passes through a frame striker plate into a recess. Apertures in a central portion of the lock plate align with apertures in a block that slides on the lock plate. A locking pin extends through registered apertures in the block and lock plate to lock the block relative to the lock plate when the block is slid against the door.
