  • Patent number: 5232086
    Abstract: A container for keys placed side-by-side. The container includes a sliding slide with a series of recesses for receiving the head of the keys. The slide is connected with a rack assembly which is in driving engagement with a pinion and a knurled wheel combination pivotably supported at one end of the container. The rack slides on a fixed smooth wall transversely extending within the container. The smooth wall includes a series of spaced cavities and a steel ball is positioned between the rack and smooth wall and is spring biased away from the rack so as to click into and out of position within the series of spaced cavities. The keys include notches for sliding on above and below transverse tracks. The tracks include a central notch. When a desired key is positioned within the central notch of each track, the key can be slid out through an opening in the end wall of the container by operation of a finger sliding tab having an internal pin which slides with the tab within a longitudinal slot.
