An improved locking system for locking a vertical array of closed drawers of a piece of furniture simultaneously upon closing an adjacent, horizontally arrayed drawer, said horizontally arrayed drawer and said vertical array of drawers separated only by means for mounting said drawers, said system comprising, in combination: a translatable actuator pin mounted generally transverse to the direction of drawer movement in said means for mounting; biasing means for the pin to bias the pin away from the vertical array of drawers and toward the adjacent horizontal drawer; a pivoting member pivotally attached to the means for mounting; pivot mounted stop members fixed to the pivoting member, in opposed relation to the vertical array of drawers, each of said stop members extending from the pivoting member generally in the direction of drawer travel as the drawers are closed, said pivoting member having a pivot axis generally transverse to the direction of drawer travel, said pivot axis also generally transverse to the direction of translation of the actuator pin; and pin drive means for driving the actuator pin, said pin drive means attached to the adjacent horizontal drawer and movable with movement of the adjacent horizontal drawer between a position of engagement with the pin when the horizontal drawer is closed to thereby translate the pin against one stop member and thereby pivot all of the stop members outwardly from the means for mounting to engage and hold the vertical array of drawers in the closed or locked position, and a position of disengagement of the pin drive means with the actuator pin when the horizontal drawer is open, said biasing means also being connected to one stop member for biasing all of the stop members to said open or unlocked position when the horizontal drawer is open and the actuator pin is disengaged by the pin drive means.
