Abstract: A self-locking lock device has a main latch element which automatically moves into a locking position when the activation is on the closing plate side. The main latch element comprises a drive element for a multipoint lock, which drives at least two additional latch elements of at least one additional latch device at a spatial distance from the main latch element. The drive element is connected to a drive device for at least one additional latch element. The drive device comprises a first drive part and a second drive part. The drive element interacts with the first drive part for a first additional latch element and with the second drive part for a second additional latch element. A movement of the first drive part and of the second drive part is synchronized with a movement of the main latch element.

Abstract: Closing device (1) with a pusher (17), a closing and opening mechanism (7) comprising at least one locking element (9), wherein the at least one locking element (9) movable by means of a latch spring (19) from an open position into a closed is characterized in that the locking spring (19) to assist the closing movement of the at least one locking element (9) in the open position has a first bias voltage by turning the pusher (17) can be generated.

Abstract: The invention relates to an electromagnetic door opener comprising a housing for installing in a door frame, a pivotable cover which can be rotated between an open position and a closed position, and a security device operating counter to a forced rotation of the cover from the closed position into the open position, which comprises a primary security step and a secondary security step. Said door opener is characterized in that the secondary security step comprises a locking element which is supported in a form fit on the base of the housing of the door opener housing.
