Abstract: A sliding-pivoting mechanism for a rack includes two pivot arms pivotably secured to the carcass, arranged parallel to one another, and forming a parallel guide for a pull-out guide having a guide rail and a running rail to which the rack is fastened. A locking mechanism is arranged on the guide rail and on one of the pivot arms to prevent a simultaneous pivoting and sliding movement. The locking mechanism has a locking pin arranged movably on one of the pivot arms and a locking plate mounted in a positionally fixed manner with respect to the guide rail and which interacts with the locking pin to block a pivoting movement of the pivot arms if the rack is lifted into an upper loading and unloading position. An unlocking device, coupled to the locking mechanism, has an actuating element and an unlocking element to move the locking pin from a blocking position into a release position.
