Cylinder assembly for plate tumbler lock

摘要

A cylinder assembly for a plate tumbler lock includes a removable, self-retained plate tumbler which snap-fits into an assembled position by pivoting the tumbler and pushing the tumbler into its ward until a projecting detent passes by a retaining ledge in the side wall of the ward. The force of the tumbler spring then pivots the tumbler into its assembled position where the detent is engaged with the retaining ledge. The pivoting of the tumbler is accomplished by locating the leg which forms the tumbler spring seat on the tumbler in a position where it does not interfere with the terminal edge which defines the open top of the ward during assembly.
