Abstract: A sliding-pivoting mechanism of a shelf of a piece of furniture or household appliance includes two pivot arms pivotally secured to a body and forming a parallel guide for a pull-out guide having at least one guide rail and a running rail. A locking mechanism is arranged on the guide rail and on one of the pivot arms for preventing a simultaneous pivoting and sliding movement.

An unlocking device is coupled to the locking mechanism and includes an actuation element and an unlocking element, with which the locking pin can be moved out of a blocking position into a release position.

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.

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.

Abstract: A pull-out guide has a guide rail, a running rail, which is mounted in a displaceable manner on the guide rail, and a braking device disposed between the guide rail and the running rail for braking the movement of the running rail relative to the guide rail.

The public-key encryption device is configured to compute a second public-key matrix (u), the second public-key matrix (u) having fewer matrix elements than the first public-key matrix (b) of the private-key decryption device. This reduces computation and bandwidth requirements at the side of the public-key encryption device.
