Abstract:
1. An improvement to a door having hinges mortised into a door jamb, the improvement comprising a door jammer mounted in a space between the door and the door jamb, the door jammer comprising: a pivoting pair of wings connected by a respective collar of each wing by a common vertical pivot pin; a first member of the pivoting pair having a fastener for attaching the first member to an edge of the door; said edge of the door also having a hinge butt plate affixed thereto; a second member of the pivoting pair having a fastener for attaching the second member to the door jamb; a collar of the second member is stationary and has a lower segment rotationally engaged in an upper segment of the first member; a collar of the first member having a female locking bushing installed therein so as to rotate with the collar of the first member; said common vertical pivot pin slidingly engaged in the collar of the second member; said pivot pin having a locking gear fixedly mounted thereto; wherein moving the common vertical pivot pin in a first direction engages the locking gear at a desired angle between the first member and the second member in the female locking bushing, thereby locking the door at the desired angle; wherein moving the common vertical pivot pin in a second direction disengages the locking gear from the female locking bushing; and wherein the female locking bushing further comprises an adjustable mount in the collar of the first member, wherein an abrasive meshing pair is mounted inside the first member affixed stationary inside the first member, and a thumbwheel on the bottom collar can adjust a spring against the lower member of the pair to lock a second member of the pair affixed to a top of the female locking bushing at a desired position relative to the first collar thereby providing a safety release to allow the door to be forcefully moved by overcoming the resistance between the abrasive meshing pair when the common vertical pivot pin is engaged in the female locking bushing.
