Abstract
A non-interlock blocking element adapted for use with a furniture unit having a plurality of drawers, a vertical guide for receiving a vertical stack of blocking elements which are slidably mountable in the guide for vertical translation therein, and a wedge element associated with each of the drawers which is reciprocable into the stack of blocking elements to effect interlocking relationships among the drawers is provided. The non-interlock blocking element allows such furniture units which are adapted for use with interlocking mechanisms, to be configured as non-interlocking furniture units, or as partially interlocking furniture units. The non-interlock blocking elements are generally similar to standard interlock blocking elements, but include a recess which allows unobstructed reciprocation of a wedge element associated with a drawer when the recess is in horizontal alignment with the wedge element, whereby the drawer can be opened irrespective of whether another drawer is already opened.
