Abstract: A cement casing for the arrangement in a depression of a floor is made from at least partial metal material, including a base plate. From the direction of the base plate, the cement casing further includes walls extending at the respective border areas of the base plate essentially vertically to the base plate in the same direction. The walls are connected to the base plate. The walls opposite the connection to the base plate have a height plane, which essentially delimits the height of the cement casing. The cement casing further includes at least one element configured for the reception of a floor door closer, as well as a further element for the arrangement of a cover plate for covering the cement casing. The cement casing includes at least one integral marking, which can be utilized for positioning the cement casing in a depression in a floor.

Abstract: The invention relates to a deadlock for a door leaf of a door, in particular to an all-glass door, including a housing, a dead bolt and dead bolt mechanics for moving the dead bolt between an opened position, in which the dead bolt is essentially disposed inside the housing, and at least one locking position, in which the dead bolt is at least partially disposed outside the housing. Furthermore, the invention relates to a mounting method for an attaching disposition of a deadlock in a centered or at least essentially centered manner at a long side of a door leaf of a door.
