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.
Claims16
A portable door locking mechanism for releasably locking a door hinged on a frame along a distal side for movement between an open position and a closed position wherein the frame includes a striker plate and a recess in the frame behind the striker plate, said mechanism comprising:
- A. a lock plate comprising an elongated planar section having an end portion for extending intermediate a door and a frame, a transversely extending tongue at said end portion for extending through a keeper into the frame recess thereby to engage the door frame, and a first pattern of apertures extending through said planar section and spaced from said end portion;
- B. a block slidably mounted on said planar section with a door engaging surface transverse to said planar section and a second pattern of apertures extending through said block such that at different relative positions of said planar section and block at least one aperture in each of said first and said second patterns of apertures come into substantial registration;
- C. a locking pin for insertion through substantially registered apertures of said first and said second patterns of apertures to fix said block relative to said plate and clamp the door to the door frame.
An integral portable door lock comprising:
- A. a lock block having a pattern of apertures formed therein;
- B. a back plate secured to said lock block to define a channel therebetween, said back plate having a second pattern of apertures formed therein in registration with said apertures in said lock block;
- C. a lock plate slidably secured in said channel and including a substantially planar sheet having first and second oppositely disposed end portions sized for positioning intermediate a door and a frame, first and second transverse tongues extending from said first and said second end portions, respectively, and a third pattern of apertures extending through said lock plate intermediate said first and second end portions, such that at different relative positions of said lock plate with respect to said lock block and back plate at least one aperture in said third pattern comes into substantial registration with one set of aligned apertures in said lock block and back plate;
- and
- D. a peg flexibly fastened to said lock block having a body for insertion through said substantially registered apertures to fix said back plate and lock block relative to said lock plate.
