<p>A shelf rack comprising corner columns which each (see fig. 4) have a row of holes to receive carrier pins (4) for the shelf (2) and have a tube profile (5) insertable into the corner column; the tube protile (5) serves as an extension and is likewise provided with holes (11) for carrier pins (4). The shelf rack is unique in that each tube profile has locking means at the bottom to fix the tube profile with respect to the corner column, and these locking means are so designed as to freely pass carrier pins protruding into the corner column. In a preferred embodiment the locking means are formed as a lock member (13) which is pivotally journalled about a pivot (14) in the tube profile (5), said lock member having a hook (19) clearing the inwardly extending carrier pins in an inactive position and engaging a hole in the corner column in an active position.</p> |
