Problems solved by technology

For example, when the door is too thick, the fastening elements on the inside of the door can cause damage or unpleasant scratches, or in the worst case it is not possible to mount the bolt to the door at all
On the other hand, when the door is too thin, the locking element may not be securely fastened to the door, in which case the reliable locking of the door may be adversely affected

Embodiment Construction

[0036] The door lock 10 generally consists of a locking element 1 , by means of which a door 3 can be secured against undesired opening, and a fastening element 2 , by means of which the locking element 1 can be connected to the door 3 .

[0037] In the context of the present invention, the term "door" is generally understood as a closing element that can be moved back and forth between an open position and a closed position. The term therefore covers (fixed at one end) covers, hatches, roofs, windows, etc. in addition to ordinary swinging or sliding doors.

[0038] As will be explained in more detail below, problems arise during assembly of the door lock when it is not adapted to the thickness of the door 3 . Hereinafter, before discussing the inventive design scheme of door lock 10, will be based on Figures 1a to 1c The assembly steps shown in are briefly described.

[0039] In order to assemble the locking element 1, the door 3 has a through hole 3.3, through which the lo...

Description

technical field [0001] The invention relates to a door lock having a locking element for locking the door in the closed state and a fastening element for fastening the locking element to the door. Furthermore, the invention also relates to a corresponding door and a method for fastening a locking element to a door. Background technique [0002] Doors of this type usually include a locking element for locking the door in the closed state so that it can no longer be opened. In order to lock the door, the locking element typically interacts in a form-fitting manner with the fixed door frame. It is known, for example, that locking elements can be hooked into or undercut a door frame, as is the case with cam locks. In order to reopen a closed and locked door, the locking element must first be moved from its locked position to an unlocked position in which it no longer interacts with the door frame and thus enables the door to be opened. [0003] In order to fasten the locking ...
