This makes space available for electronics to control and/or monitor the solenoid door lock arrangement severely limited. In future door lock arrangements, it is expected that further electronics will be built into the housing, e.g. in order to allow for e.g. sensors to register positions of different moving internal mechanism of the solenoid arrangements.
  • EP1354113 discloses a solenoid arrangement for controlling handle operation in a door lock, in which force transmission from an operation axis of a handle or the like to a follower acting on a bolt of the lock is arranged by means of a movable coupling member which receives its guidance from the solenoid arrangement.

  • An idea of said at least two supporting surfaces 816, 818 is that the actuation unit 801 of the auxiliary latch bolt 800 is caused to rotate about one of said at least two supporting surfaces 816, 818 when being displaced in a secondary direction perpendicular to the secondary plane 61.
  • Figure 13 shows an exemplifying locking member 13 that is adapted to cooperate with the auxiliary latch bolt 800 to achieve locking and unlocking of an exemplifying bolt, such as the bolt 18.
  • the locking member 13 has a hook portion 1010 adapted to engage with the bolt, whereby the bolt is prevented from being further retracted into the casing 14. Moreover, the locking member 13 has a protruding locking support 1020 adapted to engage with the guiding unit 802 when the auxiliary latch bolt 800 is in the unlocking position 702. Furthermore, the locking member 13 is biased to rotate such that the hook portion 1010 engages with the bolt unless the locking member 13 is inhibited by e.g. the gear arm 16.

  • Figure 14a illustrates when the bolt assembly 1500 is mounted in the door lock arrangement 1 and when the bolt assembly 1500 is adapted to "modern" positioning of the bolt 18.
  • Figure 14b illustrates when the bolt assembly 1500 is mounted in the door lock arrangement 1 and when the bolt assembly 1500 is adapted to "classic" positioning of the bolt 18.
  • "modern” positioning may be referred to as a first configuration of the position of the bolt 18, e.g. along the longitudinal direction of the face place when mounted in the door lock arrangement 1.
  • “classic” positioning may be referred to as a second configuration of the position of the bolt 18, , e.g.
  • the bolt 18 is extractable and retractable relatively a faceplate 10 of the door lock arrangement 1, i.e. when the bolt assembly 1500 is mounted in the door lock arrangement 1.
  • retraction, e.g. complete or almost complete retraction, of the bolt 18 allows the door to freely swing in and out of the door frame, e.g. without being obstructed by the bolt 18.
  • extraction, e.g. complete or almost complete extraction, of the bolt 18 secures the door in the door frame by means of the bolt 18. This means that it is not possible to open the door without operating a handle of the door, or a key for the door lock arrangement 1.
  • Releasable attachment of the bolt 18 may refer to that the bolt may be inserted into the attachment portion and temporarily fastened therein and to that the bolt may, e.g. at a later point in time, be released from the attachment portion, e.g. to be moved to the other attachment portion or replaced with a further bolt, which may be different (for left/right hinged door) alternatively the same or similar as the released bolt.
  • the bolt assembly enables a change or a swap of a position of the bolt in that the position of the bolt may for example be chosen according to the "classic" or "modern” positioning by attaching the bolt in the first or second attachment portion, respectively.
  • the bolt 18 may be released and fastened by proper screwing at screws 1702, 1704 (see Figure 17c ) which are accessible, since the casing of the door lock arrangement 1 comprises suitable openings 1420, 1422. The screws may not need to be completely unscrewed to release the bolt 18.
  • the bolt assembly 1500 comprises the faceplate 10 and a cover plate 1506.
  • the cover plate 1506 and/or the faceplate 10 may be realized in according to different examples, some of which being illustrated herein.
  • the faceplate 10 has a recess 1508 that is adapted to accommodate the cover plate 1506.
  • the cover plate 1506 is releasably mountable at the faceplate 10.

  • the cover plate 1506 is adapted to cover the second attachment portion 1504 when the cover plate 1506 is mounted at the faceplate 10.
  • cover plate 1506 and/or the faceplate 10 is illustrated in Figure 15a through Figure 15c .
  • one and the same cover plate 1506 may be used for both "classic" and "modern” positioning depending on how the cover plate 1506 is mounted, i.e. in terms of orientation.
  • the cover plate 1506 when the cover plate 1506 is mounted with a first end 1401 towards a first end 1411 of the face plate, it may be that the bolt assembly is adapted to "modern” positioning.
  • the cover plate 1506 is mounted with a second end 1402 towards the first end 1411 of the face plate, it may be that the bolt assembly is adapted to "classic” positioning.
  • the first and second ends 1401, 1402 of the cover plate 1506 are located in opposite ends of the cover plate, e.g. relatively a longitudinal direction 1505 thereof.
  • “Reversibly mountable” may refer to that the orientation of the cover plate 1506 may be switched, such as swapped, changed or the like. As described above, the cover plate 1506 may be oriented in two different ways, one for "classic” positioning and one for "modern” positioning.
  • the first mode may yield a first opening position of the opening 1507.
  • the first opening position is located at a distance from the center 1501, still along the longitudinal axis of the faceplate, thus also in the longitudinal direction 1505 of the cover plate 1506.
  • the second mode may yield a second opening position of the opening 1507.
  • the second opening position is located at the distance, i.e. the same distance, from the center 1501, again still along the longitudinal axis of the faceplate, thus again also in the longitudinal direction of the cover plate 1506.

  • Figure 17b shows that the first attachment portion 1502 may be vacant, in case the bolt 18 is mounted in the second attachment portion 1504.
  • Figure 17c illustrates two screws 1702, 1704 for securing the bolt 18. Normally, only one screw is needed, since said only one screw may be used in either of two screw holes, illustrated in more detail with reference to Figure 17e , in one or the other of the first and second attachment portions 1502, 1504. In this example, the bolt 18 is mounted at the second attachment portion 1504 by means of the screw 1704.
