Abstract: A door locking system includes two door handle units and a mounting device. The mounting device includes two mounting plates and two mounting pins. The mounting pins are fixed radially and axially in the mounting plates, and the mounting plates are secured coaxially at an axial distance. Each door handle unit is secured on the respective mounting plate, facing away from the mounting pins. Further, in the first mounting plate, two first openings are formed in which the two mounting pins are received. The first openings are formed by flaps pivoted to the mounting plate. The flaps can together be brought into a mounting position and into a blocking position by a blocking unit. In the mounting position, the flaps are freely pivotable, and in the blocking position, the flaps are pressed on toward the respective mounting pin by the blocking unit.

Abstract: A door locking system for opening and closing a door lock in a door. The door locking system includes a first door handle unit with a first door handle and a second door handle unit with a second door handle. The first door handle and the second door handle are pivotable about a common pivot axis. The door locking system comprises a coupling device with an axially aligned polygonal pin which has two pin pieces. The respective pin piece is connected to the respective door handle in a pivotably fixed manner.

Abstract: Provided is a door fitting, with an outer doorplate and with an inner doorplate, wherein the outer doorplate has a first opening on an inner side facing the inner doorplate, into which a shaft of a first screw can be screwed to fasten the outer doorplate to the door, and a second opening at a distance from the first end section in the lengthwise direction of the door fitting, into which a shaft of a second screw can be screwed to fasten the outer doorplate to the door. The door fitting can be adapted to various fitting situations if the first opening and/or the second opening is/are arranged on the outer doorplate so as to be displaceable in the lengthwise direction of the door fitting to allow different relative positions to be set between the outer doorplate and the first opening and/or the second opening.
