Definitions

  • the invention relates to a locking system for doors or windows according to the preamble of patent claim 1.
  • Locking systems for doors and windows are known in a wide variety of designs. These usually comprise an opening and/or closing mechanism, for example in the form of a mortise lock, which can be inserted into a recess provided in the door or window.
  • known locking systems have at least one driver element for mechanically connecting a handle to the opening and/or closing mechanism of the locking system, in particular with a nut element rotatably received therein, wherein the driver element is guided outwards via at least one through-hole in the door or window and the handle is mounted on its free end section protruding from the door or window.
  • the through-hole in the door or window is usually covered by a door rosette or rosette, wherein the rosette can also additionally serve to receive and/or guide the free end of the neck section of the handle.
  • the rosette is mounted directly on the door or door leaf or the window or window frame.
  • the driver element is guided through a preferably central opening or through hole in the rosette, i.e. the rosette mounted on the door leaf or window frame preferably surrounds the driver element concentrically.
  • the rosette is preferably screwed directly onto the door leaf or window frame.
  • the disadvantage of such screw connections is that they are not very stable due to the materials used to manufacture the door leaves or window frames, because the rosette in particular engages via connecting pins in pre-drilled holes in the door or window, which are also designed to accommodate the screw means.
  • the pre-drilled holes for the connecting pins and/or screw means are not yet present in the door and often have to be made in the door or window when the locking system is installed, which can disadvantageously result in the rosette being arranged eccentrically to the axis of rotation.
  • the holes in the door leaf or window frame provided for the passage of the driver element are not standardized, so that the driver element accommodated in the box lock is often not centered in relation to this hole, which makes it difficult to position the rosette on the door or window in a stable manner and concentric with the axis of rotation of the driver element.
  • a locking system for doors or windows is already known in which the rosette is screwed into the thread provided by a threaded plate attached directly to the mortise lock.
  • the rosette has a reduced cross-section connecting flange section with an external thread that can be screwed into the internal thread of the threaded plate.
  • the threaded plate is mounted on the mortise lock in a rotationally fixed manner and is inserted into a recess in the door or window together with the mortise lock.
  • the EN 10 2019 121 354 A1 discloses a locking system for mounting on a door leaf or a window frame, also comprising a mortise lock and a rosette that can be screwed into a threaded part, a handle and a pin-like driver element.
  • the threaded part is secured by means of a securing means directly and in a rotationally fixed manner between the door leaf or window frame and the mortise lock accommodated in a recess in the door leaf or window frame.
  • the securing element is formed by a U-shaped bracket that encloses the mortise lock in sections.
  • the disadvantage of the known locking systems is that they require an additional, separate component to attach the rosette to the mortise lock, which must be provided between the door leaf or window frame with or before the mortise lock is installed in the recess of the door or window. It is not possible to subsequently insert the fastening or security part after the mortise lock has been installed in the door leaf.
  • the invention is based on the object of specifying a locking system for doors or windows which eliminates the disadvantages known from the prior art and which enables a connection with high axial strength between the rosette and the mortise lock and, in addition, has a simple and cost-effective construction compared to the prior art.
  • a first free end section of the threaded sleeve is received in the internal thread of the threaded element and a second free end section of the threaded sleeve protrudes outwards from the mortise lock.
  • the protruding free end section of the threaded sleeve advantageously forms an assembly area that is easily accessible from the outside for the subsequent assembly of the rosette, which has an exact positioning with regard to the axis of rotation or the mortise lock.
  • the arrangement of the rosette with regard to the axis of rotation or with regard to the mortise lock is therefore independent of the design of the through hole in the door or window. It is therefore particularly advantageous for the connecting sleeve or threaded sleeve to extend along the axis of rotation in the assembled state and surround it concentrically.
  • the rosette can be screwed onto the external thread of the threaded sleeve.
  • the rosette is preferably designed in several parts and has at least a rosette body and a rosette cover, wherein the rosette cover can preferably be plugged onto the rosette body.
  • the rosette body particularly preferably has a plate-shaped contact section and a sleeve section immediately adjacent to it, wherein the rosette body comprises an internal thread extending at least over the sleeve section.
  • the lock housing advantageously has a preferably circular opening in which the preferably ring-shaped connecting element, in particular a threaded element, is accommodated in a rotationally fixed manner.
  • the connecting element can also be formed in one piece with the lock housing or connected to it in a material-locking manner.
  • a door 2 in the sense of the invention is understood to mean the leaf or wing of a door 2, which is usually accommodated in a door frame. It is understood that the locking system 1 according to the invention can also be used in a window or its window frame, without thereby departing from the inventive concept.
  • the rosette 5, 5' is provided to cover the through-hole made in the door 2 or the window for the driver element 4 to pass through and also serves as a guide for the handle 6, 6' which is immediately adjacent to it or engages in it in sections.
  • so-called "mini" rosettes are shown, the outer diameter of which is only slightly larger than the diameter of the handle 6, 6'.
  • the lock housing 3.3 of the mortise lock 3 is box-shaped and designed to accommodate the opening and/or closing mechanism.
  • the box-shaped lock housing 3.3 is made of metal, in particular a flat metal material, preferably a metal sheet.
  • Part of the opening and/or closing mechanism accommodated in the lock housing 3.3 is a rotatably mounted nut element 3.4, which creates an operative connection between the driver element 4 and other components of the opening and/or closing mechanism, in particular the latch 3.1, the bolt 3.2 and the locking cylinder.
  • driver element 4 There is preferably a positive connection between the driver element 4 and the nut element 3.4 and the driver element 4 can be inserted into the nut element 3.4 to create the positive connection even after the mortise lock 3 has been installed in the door 2 via through holes in the door 2 that release the nut element 3.4 and associated openings in the lock housing 3.3.
  • the at least one handle 6, 6' and the driver element 4 have a common pivoting or rotational axis RA, whereby the nut element 3.4 receiving the driver element 4 is also mounted in the mortise lock 3 so that it can rotate about the rotational axis RA.
  • the driver element 4 is operatively connected to the latch 3.1 via the nut element 3.4 in such a way that the pivoting movement generated by the handle 6, 6' is first converted into a pivoting or rotational movement of the driver element 4 and finally into a return movement of the latch 3.1.
  • the handle 6 comprises, for example, a neck section 6.1 and an adjoining elongated pusher section 6.2, wherein the neck section 6.1 extends along and concentrically around the pivot or rotation axis RA and the pusher section 6.2 of the handle 6 extends along a pusher longitudinal axis that projects laterally radially from the pivot or rotation axis RA and preferably runs perpendicular to the pivot or rotation axis RA.
  • the handle 6, 6' is thus connected to the free end of the driver element 4 in a rotationally fixed manner about the rotation axis RA.
  • the axial fixation of the handle 6, 6' on the driver element 4 can be carried out, for example, via a grub screw received in the neck section 6.1 radially to the rotation axis RA or a clamping device integrated in the neck section 6.1.
  • the mortise lock 3 has a connecting element 7, 7' which surrounds the driver element 4 in a ring shape.
  • the connecting element 7, 7' is preferably implemented as a threaded element 7, 7' with a thread 7.1, 7.1', wherein the threaded element 7, 7' is preferably formed by a separate component, namely an annular threaded element 7, 7', which is received in a preferably circular opening 3.5 in the lock housing 3.3.
  • the thread 7.1, 7.1' is preferably designed as an internal thread.
  • the ring-shaped threaded element 7, 7' is mounted or integrated in the opening 3.5 in the lock housing 3.3 in a rotationally and tensile-resistant manner and concentrically surrounds the driver element 4 guided through the lock housing 3.3.
  • annular threaded element 7, 7' is already accommodated in the lock housing 3.3, wherein the diameter of the annular threaded element 7, 7' designed as a threaded ring is selected such that access to the nut element 3.4 accommodated in the lock housing 3.3 is provided.
  • the thread or internal thread 7.1, 7.1' is preferably designed as a fine thread with a narrower thread profile compared to a standard thread, and particularly preferably as a metric fine thread.
  • At least one connecting sleeve 8, 8' is provided, which can be connected to the connecting element 7, 7'.
  • the connecting sleeve 8, 8' is preferably implemented as a threaded sleeve.
  • a first and second threaded sleeve 8, 8' are provided, which are designed for mounting a first and second rosette 5, 5' on the mortise lock 3.
  • the first and second threaded sleeve 8, 8' have, for example, a different sleeve length along the rotation axis RA, namely the first threaded sleeve 8 is longer than the second threaded sleeve 8', which is due to the installation situation of the mortise lock 3 in the door 2.
  • the threaded sleeve 8, 8' has a thread 8.1, 8.1', which is preferably designed as an external thread that extends along the outer surface of the threaded sleeve 8, 8'.
  • the external thread 8.1, 8.1' is designed such that it can be screwed into the internal thread 7.1, 7.1' of the threaded element 7, 7'.
  • the thread profile of the external thread 8.1, 8.1' is adapted to the thread profile of the internal thread 7.1, 7.1', whereby the external thread 8.1, 8.1' also preferably designed as a fine thread, particularly preferably as a metric fine thread.
  • the latter In order to guide the driver element 4 through the threaded sleeve 8, 8', the latter has a sleeve interior which is adapted in terms of its cross section and diameter to the driver element 4 to be passed through, in such a way that rotation of the driver element 4 about the axis of rotation RA is also possible without any problems when the threaded sleeve 8, 8' is firmly screwed to the lock housing 3.3.
  • the sleeve interior can, for example, have a multi-edged cross section which forms an internal polygon.
  • the internal polygon is preferably implemented in the form of an internal square or an internal hexagon or an internal octagon.
  • the sleeve interior has a hexagonal cross-section that extends unchanged over the entire sleeve length along the rotation axis RA.
  • the longitudinal axis of the threaded sleeve 8, 8' coincides with the rotation axis RA, so that the external thread 8.1, 8.1' runs concentrically around the rotation axis RA.
  • the sleeve interior thus advantageously forms a hexagon socket to enable the threaded sleeve 8, 8' to be screwed in and tightened in the threaded element 7, 7' using conventional assembly aids.
  • the threaded sleeve 8, 8' has a lock ring element 8.2, 8.2', which can be screwed onto the external thread 8.1, 8.1' provided on the outer circumferential surface of the threaded sleeve 8, 8', whereby the threaded sleeve 8, 8' screwed into the threaded element 7, 7' is secured against spontaneously loosening from the mortise lock 3 by means of the lock ring element 8.2, 8.2'.
  • the lock ring element 8.2, 8.2' can be brought into direct contact with the outside of the threaded element 7, 7' or with the section of the lock housing 3.3 surrounding the opening 3.5, so that a friction and/or clamping connection is created.
  • the rosette 5, 5' can be connected to the annular threaded element 7, 7' via the threaded sleeve 8, 8', i.e. the rosette 5, 5' can be connected directly to the annular threaded element 7, 7' accommodated in the lock housing 3.3 and thus to the mortise lock 3 by means of the threaded sleeve 8, 8', preferably by means of a detachable connection in the form of a screw connection.
  • a first free end section of the threaded sleeve 8, 8' is accommodated in the internal thread 7.1, 7.1' of the threaded element 7, 7' and a second free end section of the threaded sleeve 8, 8' protrudes outwards from the mortise lock 3, namely along the rotation axis RA of the lock housing 3.3.
  • the second end section forms the connection area for the rosette 5, 5', which is preferably completely received in the through hole in the door 2 or the door leaf.
  • the rosette 5, 5' is preferably designed in several parts and has a rosette body 5.1, 5.1' and a rosette cover 5.2, 5.2', which can be plugged onto the rosette body 5.1, 5.1'.
  • the rosette body 5.1, 5.1' of the rosette 5, 5' comprises a plate-shaped contact section 5.11, 5.11' and a sleeve section 5.12, 5.12' immediately adjacent to it, whereby in the present embodiment the rosette body 5.1, 5.1' has an internal thread 5.13, 5.13' extending at least over the sleeve section 5.12, 5.12'.
  • the plate-shaped contact section 5.11, 5.11' preferably has a circular cross-section with an annular front surface, wherein the annular front surface encloses a through hole with a circular opening that merges into the interior of the sleeve section 5.12.
  • the annular front surface is completely covered by the rosette cover 5.2, 5.2', which also extends over the lateral edge of the plate-shaped contact section 5.11, 5.11' and also completely covers it.
  • the rosette cover 5.2, 5.2' also has a circular opening, which is preferably congruent with the through hole in the plate-shaped contact section 5.11, 5.11' and approximately corresponds to the cross section of the neck section 6.1 of the handle 6.
  • a circular cover plate 5.3, 5.3' is provided, which has a central opening adapted to the cross-sectional shape of the driver element 4.
  • the circular cover plate 5.3, 5.3' can be attached to the driver element 4 after mounting the rosette 5, 5' on the mortise lock 3 and preferably completely closes the circular opening in the rosette cover 5.2, 5.2'.
  • the central opening in the circular cover plate 5.3, 5.3' has a square cross-section adapted to the cross-sectional shape of the driver element 4, as can be seen for example from the Figures 3 , 5 and 6 visible.
  • the length of the threaded sleeve 8, 8' is adapted to the length of the respective through hole from the outer surface of the door 2 to the recess in the door 2, whereby the screw-in depth of the first end section of the threaded sleeve 8, 8' into the annular Threaded element 7, 7' can be adjusted by arranging the lock ring element 8.2, 8.2' in the first end section of the threaded sleeve 8, 8'.
  • the length of the sleeve section 5.12, 5.12' of the rosette body 5.1, 5.1' is also selected depending on the installation situation of the mortise lock 3 in the door 3, and in the present embodiment the rosette body 5.1 of the first rosette 5 has a longer sleeve section 5.12 than the rosette body 5.1' of the second rosette 5'.
