US Patent 7607701 Adjustable latch

An adjustable door latch that enables one to adjust its length without removing any functionality from other areas of the door latch assembly. The improved door latch assembly includes a strike plate, adjustment head, adjustment stem, resilient member, and housing. The improved door latch utilizes a threaded adjustment head, which is screwed into an adjustment stem. The adjustment stem has a threaded aperture located on the front surface of a circular disc. The circular disc has at least one rib, which fits into the groove of a drum, this configuration prevents rotation of the circular disc when adjustment is necessary. The adjustment member and stem have apertures that allow one to thread the spindle of a door knob through the door latch assembly and to the other door knob.
