Flush bolt and door-sealing system

A door-sealing system having a door seal and a flush-bolt mechanism, the flush-bolt mechanism

• having a fastening rail for fastening the flush-bolt mechanism in or on a door leaf,
• having an actuating mechanism, and
• having a locking bolt,
• wherein the actuating mechanism comprises a triggering element for automatically displacing the locking bolt from a starting position into a locking position, and also comprises a restoring spring for restoring the locking bolt from the locking position into the starting position,
• wherein the flush-bolt mechanism has an automatic override function which, in the event of misalignment of the locking bolt, automatically overrides the actuating mechanism in order to prevent the locking bolt from being lowered all the way into the locking position, wherein the locking bolt has a longitudinal center axis,
• wherein
• the actuating mechanism has a displacement element, on which the locking bolt rests by way of a driver, wherein the locking bolt can be brought into the locking position by virtue of the displacement element being moved, and wherein the displacement element can be brought into the starting position, together with the driver resting thereon and the locking bolt, by means of the restoring spring,
• wherein the displacement element can be displaced in the direction of the longitudinal center axis relative to the locking bolt and driver, and wherein overriding takes place by virtue of this displacement capability,
• wherein the door seal has a seal housing and a sealing element, and wherein the seal housing and the sealing element each have a through-passage opening through which to guide the locking bolt.
