Abstract

The invention relates to a door lock (1) for a door or window or the like, wherein the door lock (1) has a lock housing (1g) comprising a lock base, a lock top, and a lock faceplate (1s), wherein the door lock has a tilting latch (2) which is linearly movable between a closed position and a forward-locked position and can be moved to a forward-locked position. The door lock (1) has a tilting latch bearing in which the tilting latch shaft (2s) is linearly movably guided. The door lock (1) has a limiting element (3) that is movable between a limiting position, in which the limiting element interacts with the tilt latch shaft and/or the tilt latch head (2k) and limits the linear movement of the tilt latch (2), so that the tilt latch can only be moved between the closed position and the forward-locked position, and a release position, in which the limiting element (3) is out of engagement with the tilt latch shaft and/or the tilt latch head, so that the tilt latch (2) can be moved between the closed position and an extended position, in which the tilt latch (2) protrudes further from the lock housing (1g) than in the forward-locked position.

Description

The present invention relates to a door lock according to the features of the preamble of claim 1 and a method according to claim 15. document DE 10 2020 111 229 A1 This describes a door lock with a tilting latch that can be reversed by 180° when the lock is installed on both left- and right-hinged doors. The door lock has a lock housing with a faceplate attached to the housing. A tilting latch is slidably mounted within the lock housing. The tilting latch has a latch head and a latch shaft, which are connected by a linkage. This linkage can be detached without tools and includes two opposing bearing points to support the latch head on the latch shaft. Detaching and repositioning the latch head is only possible after the faceplate has been removed from the lock housing. A disadvantage is that a tool is required to detach the faceplate from the lock housing. The utility model DE 93 04 388 This shows a lock with a reversible latch. The latch is held in the lock by a locking element in the form of a screw. To change the latch position, this screw is loosened and pulled out of the lock housing. The latch can then be moved into the reversible position and switched. Finally, the locking element, in the form of the screw, must be pushed back into the lock and tightened. It is an object of the present invention to provide a door lock with a tilting latch that can be reversed by 180°, i.e., a tilting latch that can be reversed to the right or left. Preferably, the reversal should be possible without tools. In particular, the reversal of the tilting latch should only be possible when the lock is removed. This problem is solved according to the invention by a door lock according to the features of claim 1 and by a method according to the features of claim 13. A door lock for a door or window or the like is proposed, wherein the door lock has a lock housing comprising a lock base, a lock top and a lock faceplate, wherein the door lock has a tilting latch which is linearly movable between a closed position and a forward-locked position, and the tilting latch comprises a tilting latch head and a tilting latch shaft, wherein the tilting latch head is pivotably mounted on the tilting latch shaft (2t), wherein the pivot axis of the tilting latch head runs parallel to the longitudinal axis of the lock faceplate. wherein the door lock has a tilting latch bearing in which the tilting latch shaft is guided in a linearly movable manner. The essential point is that the door lock has a limiting element that is linearly movable and mounted in a receptacle of the tilt latch bearing, and that the limiting element is movable between a limiting position and a release position. wherein the limiting element in the limiting position interacts with the tilting latch shaft and/or the tilting latch head and limits the linear movement of the tilting latch in such a way that the tilting latch can only be moved between the closed position and the forward-closed position, and wherein in the release position the limiting element is out of engagement with the tilting latch shaft and/or the tilting latch head, so that the tilting latch can be moved between the closed position and an extended position in which the tilting latch protrudes further from the lock housing than in the forward-closed position, so that the tilting latch head and/or the tilting latch shaft can be rotated about the longitudinal axis of the tilting latch shaft in order to change the position of the tilting latch. Preferably, a door lock is understood to be a mortise lock or built-in lock, which may include a lock housing with a lock top and a lock bottom, as well as a lock faceplate. Preferably, a tilting trap is understood here to be a lock trap having a tilting trap head and a tilting trap shaft, wherein the tilting trap head is pivotably mounted on the tilting trap shaft. For example, unlike a snap-action trap, a tilting trap cannot be actively retracted, for example by operating a lock nut. Preferably, the tilting trap can be switched between a pre-closed position and a The locking mechanism should be movable in the closed position. Preferably, in the forward-closed position, the tip of the wedge-shaped tilting latch head projects beyond the lock faceplate by a first predetermined length. In the closed position, the tilting latch head is retracted into the lock housing, with the tip of the wedge-shaped tilting latch head projecting beyond the lock faceplate by only a few millimeters or being completely enclosed within the lock housing. Preferably, the tilt latch can be moved into an extended position. In particular, in the extended position, the tip of the wedge-shaped tilt latch head projects beyond the lock faceplate by a second predetermined length, which is greater than the first predetermined length. The extended position allows the tilt latch head to be rotated around the longitudinal axis of the tilt latch shaft. This allows the tilt latch to be oriented during in
