A shelf box is designed for use with a shelf rack or storage cabinet open on both sides so that the shelf box can be removed from either side of the rack or cabinet. Two stop members are respectively mounted adjacent to opposite ends of the shelf box for pivotal movement between stop and release positions, and are interconnected by a pivoting linkage so that when one stop member is in its stop position the other stop member is in its release position. The stop members are disposed so that in their stop positions they are engageable with retaining portions of the overlying shelf. Thus, when one end of the shelf box is withdrawn from the rack or cabinet it will be stopped by engagement of the adjacent shelf retaining portion with the stop member at the opposite end of the shelf box in its stop position to prevent inadvertent complete removal of the shelf box. If the stop member adjacent to the end being withdrawn is in the stop position it will engage the adjacent shelf retaining portion for cammed movement of the stop member to its release position, thereby simultaneously moving the stop member at the opposite end of the shelf box to its stop position. The linkage interconnecting the stop members provides bearing surfaces for non-snagging sliding of side-by-side shelf boxes with respect to each other.

A shelf box for use at either side of a shelf rack which is open at opposite sides thereof and includes a plurality of parallel spaced-apart shelves each having two retaining portions extending downwardly therefrom along the entire length thereof, said shelf box comprising an open-top receptacle having opposed ends and being adapted for slidable disposition between adjacent ones of the associated shelves from either side thereof anywhere along the length thereof and dimensioned longitudinally to extend substantially from one side to the other side of the associated rack, with no portion of said receptacle extending above the retaining portions of the overlying shelf, a first stop member mounted on said receptacle adjacent to a first one of said ends for movement between a stop position extending upwardly above the top of said receptacle and engageable with the retaining portions of one of the adjacent shelves and a release position non-engageable with the retaining portions of the shelves, a second stop member mounted on said receptacle adjacent to a second one of said ends for movement between a stop position extending upwardly above the top of said receptacle and engageable with the retaining portions of one of the adjacent shelves and a release position non-engageable with the retaining portions of the shelves, each of said stop members in the release position thereof accommodating withdrawal of the adjacent end of said receptacle from the associated rack, each of said stop members in the stop position thereof being engageable with one of the associated retaining portions for movement of said stop member to the release position thereof to accommodate withdrawal of the adjacent end of said receptacle from the associated rack and being engageable with the other of the associated retaining portions for limiting withdrawal of the opposite end of said receptacle from the associated rack, and control means for effecting movement of each of said stop members from the release position to the stop position thereof, whereby said shelf box may be opened from either side of the rack while preventing inadvertent complete removal of the shelf box from the rack.
