An improved interlocking mechanism for a cabinet

Abstract

The present invention discloses a cabinet (100) comprising a plurality of drawers (101) and an interlocking mechanism (200). The interlocking mechanism (200) comprises a locking bar (201) having a plurality of spaced protrusions (202), and a plurality of rotatable blocks (203) having a first portion (204) pivotably connected to an inner side wall of the cabinet (100), a second portion (205) engageable by the sliding mechanism (102) of a respective drawer (101), and a third portion (206) that is engageable with one of the protrusions (202), wherein when one of the drawers (101) is moving towards the open position, the sliding mechanism (102) of that particular drawer (101) engages the second portion (205) of the corresponding rotatable block (203) to cause the third portion (206) of the corresponding rotatable block (203) to engage with the respective protrusions (202) and to move the locking bar (201) to a locked position, the remaining protrusions (202) of the locking bar (201) are also moved to a position that intercept a rotation pathway of the remaining rotatable blocks (203) such that the sliding mechanisms (102) of the remaining drawers (101) are prevented from movement.
