  "abstract": "In an automatically operable rack for storing workpieces in ratchet columns with side walls ( 1.1, 1.2 ), between which movable ratchets ( 5 ) are arranged which serve to hold the workpieces, wherein the ratchets ( 5 ) can be brought from a rest position into a working position in which they hold the workpiece, and a locking/unlocking unit is assigned to the last ratchet ( 5.2 ), the locking being affected by a rotary movement of the last ratchet ( 5.2 ) into its working position, the rotary movement of the last ratchet ( 5.2 ) entrains a bolt ( 9 ) which is received by a recess ( 12, 49 ) when the working position is reached.",
