The bolt assembly (1500) comprises a bolt guiding member (1509) having a first and a second attachment portion (1502, 1504) for releasable attachment of the bolt (18) to the bolt guiding member (1509), wherein the second attachment portion (1504) is offset the first attachment portion (1502) along a longitudinal axis (62) of the faceplate (10).

Description

Bolt assembly with bolt guiding member with first and second attachment portions allowing alternating mounting, and door lock arrangement TECHNICAL FIELD The present invention relates to door lock arrangements for mounting in doors. ln particular, it is herein disclosed a door lock arrangement and a bolt assembly.

BACKGROUND Door lock arrangements have a vast range of applications, such as at hotels, hospitals, offices or the like. For these applications, for example solenoid locks are particularly popular. A common type of solenoid locks is activated, e.g. unlocked, by means of a Radio Frequency Identification (RFID) tag, a magnetic card or the like. With a solenoid lock of this type, a locking mechanism of the solenoid lock cannot be operated through actuation of a door handle unless the solenoid lock is electrically activated (Power-To-Open type locking arrangements). Some solenoid locks allow the door handle to operate the locking mechanism without power and do instead require power to deactivate the door handle, i.e. the door is locked when electrically activated (Power-To-Lock type locking arrangements). These door lock arrangements also often include a knob for manually locking and unlocking the door, where the knob is only mounted at one side of the door, or the door lock arrangement.

A known door lock arrangement typically has a dead bolt or the like for locking of the door in which the door lock arrangement is mounted. A position, along a longitudinal direction of a faceplate of the door lock arrangement, of the dead bolt is usually called ”classic” or ”modern” positioning. This means that a door with a door lock arrangement with ”classic” positioning of the dead bolt should not be installed in a door frame adapted for a door lock arrangement with ”modern” positioning of the dead bolt. Since if the door would be installed in that door frame the deadbolt would not coincide with a corresponding cavity that is adapted to receive the deadbolt. ln some cases, the door frame may be adapted, but in some other cases it may not be desired to adapt the door frame, e.g. due to fire safety and/or security reasons. For lock manufacturers, this implies that door lock arrangements need to be provided in different versions, one for ”classic” positioning and another for ”modern” positioning. A disadvantage is that maintaining different versions adds costs. A further disadvantage may be that door lock arrangements in stock may not always fit desired need in terms of ”classic” or ”modern” positioning. Sometimes, the term ”connect” is also used to refer to the same position as "modern".

SUMMARY ln view of the above, an object may be to alleviate or at least reduce one or more of the abovementioned disadvantages and/or problems.

This object, and other objects, may be achieved by the independent claims appended herewith.

According to an aspect, there is hence provided a bolt assembly adapted to attach a bolt of a door lock arrangement, the bolt being extractable and retractable relatively a faceplate of the door lock arrangement. The bolt assembly comprises a bolt guiding member, having a first attachment portion for releasable attachment of the bolt to the bolt guiding member and being arranged to translationally guide the bolt along a geometrical axis that is perpendicular to a main plane of the faceplate for extraction and retraction of the bolt relatively the faceplate, when the bolt guiding member is mounted in the door lock arrangement. The bolt guiding member has a second attachment portion for releasable attachment of the bolt to the bolt guiding member. The second attachment portion is offset the first attachment portion along, such as parallelly with, a longitudinal axis of the faceplate when the bolt guiding member is mounted in the door lock arrangement. ln this manner, 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. Accordingly, a length of the offset between the first and second attachment portions may typically be defined by a difference in position of the bolt according to ”classic” and "modern", respectively.

Thanks to the second attachment portion, the bolt assembly enables adaption to ”classic” or ”modern” positioning in an easy manner which requires few, or no, parts that are specifically provided for only one of the ”classic” and ”modern” positioning. ln some embodiments, the bolt assembly comprises the faceplate and a cover plate. The faceplate has a recess adapted to accommodate the cover plate. The recess may typically face away from an interior of a door lock assembly together with which the bolt assembly is used, e.g. mounted. The cover plate is releasably mountable at the faceplate. The cover plate comprises an opening, which is adapted to allow the extraction and the retraction of the bolt when the bolt is attached to the first attachment portion and when the cover plate is mounted at the faceplate, and wherein the cover plate is adapted to cover the second attachment portion when the cover plate is mounted at the faceplate. For example, a shape of the opening in the cover plate is derived from a contour of the bolt, wherein the contour is seen in a cross-section that is parallel with the faceplate when the cover plate is mounted at the faceplate. Further, a position of the opening in the cover plate may also be located oppositely to the first attachment portion when the cover plate is mounted at the faceplate.

Thanks to the cover plate, the second attachment portion is protected. An advantage may be that manipulation of the lock with a tool, such as a picklock or the like, may be hindered, or obstructed. ln some embodiments, the cover plate is reversibly mountable at the faceplate. The opening is offset along the longitudinal axis of the faceplate relatively a center in a longitudinal direction of the cover plate when the cover plate is mounted at the faceplate. A length of the offset is adapted to allow the bolt to be alternatingly mounted at the first and second attachment portions upon reversed re-mounting of the cover plate.

As an example, the cover plate may thus be mountable in the faceplate in a first mode and a second mode. The first mode may yield a first opening position of the opening. The first opening position is located at a distance from the center, still along the longitudinal axis of the faceplate, thus also in a longitudinal direction of the cover plate. The second mode may yield a second opening position of the opening. The second opening position is located at the distance, i.e. the same distance, from the center, again still along the longitudinal axis of the faceplate, thus again also in the longitudinal direction of the cover plate. The cover plate may thus be reversibly mountable to assume the first mode or the second mode.

As a further example, the recess may snugly fit to a shape of the cover plate, whereby the center of the cover plate is at a center position, e.g. one and the same position. The center position of the center is thus assumed both when the cover plate is mounted in the first mode and when the cover plate is mounted in the second mode. ln this manner, the cover plate, i.e. one and the same cover plate, may be reversely mounted to adapt to door frames configured for ”modern” or ”classic” positioning of the bolt. An advantage is, hence, that the same cover plate may be used for both ”modern” and ”classic” positioning of the bolt. A further advantage may be that there is to bring special parts in order to be able to change the bolt position from ”modern” to ”classic” or the other way around. As a consequence, there is no requirement of being able to foresee the change of the bolt position, e.g. before arriving at a site of installation and/or leaving a supply of door lock parts. ln some embodiments, the faceplate is arranged to allow mounting of the cover plate at a first location and a second location. The first location is offset the second location along the longitudinal axis of the faceplate.

As an example, the recess is shaped to accommodate the cover plate both when the cover plate is mounted at the first location, e.g. within the recess, and when the cover plate is mounted at the second location, e.g. within the recess. ln some embodiments, the cover plate is non-reversibly mountable at the faceplate. The opening is offset along the longitudinal axis of the faceplate relatively an end of the faceplate. A length of the offset is adapted to allow the bolt to be mounted at the first or second attachment portions.

As an example, the cover plate may be provided as a first cover plate or a second cover plate. With the first cover plate, the length of the offset may be adapted to allow the bolt to be mounted at the first attachment portion. ln more detail, the opening of the first cover plate may be positioned in line with the first attachment portion when seen along the geometrical axis, e.g. through a center of the opening of the first cover plate. With the second cover plate, the length of the offset may be adapted to allow the bolt to be mounted at the second attachment portion. ln more detail, the opening of the second cover plate may be positioned in line with the second attachment portion when seen along the geometrical axis, e.g. through a center of the opening of the second cover plate. The first cover plate is thus different from the second cover plate. This means that the cover plate is provided in two different versions, one for ”classic” positioning and one for ”modern” positioning. ln a further example, according to the same basic principle as directly above, there may be provided a first face plate and a second face plate, each having a respective opening, whose location along the longitudinal axis of the faceplate corresponds to, or matches with, the first or second attachment portion. The first face plate is different from the second face plate. This means that the face plate is provided in two different versions, one for ”classic” positioning and one for ”modern” positioning. ln some embodiments, the bolt assembly further comprises an attachment portion cover adapted to be releasably mountable at the first and second attachment portion alternatingly. As an example, the attachment portion cover may be alternatingly mounted, such as releasably mounted, in the first or second attachment portion. The attachment portion cover is further adapted to present a flat surface facing away from the bolt guiding member when mounted in the first or second attachment portion.

The flat surface may be aligned with the faceplate when the bolt is in an extracted position. Alternatively, with embodiments including the cover plate, the flat surface may be aligned with a bolt guiding member surface of the bolt guiding member. The bolt guiding member surface faces the face plate when the bolt assembly is used, or mounted, together with a door lock arrangement.

An advantage may be that the attachment portion cover protects the one of the first and second attachment portions that the bolt is not mounted in. The attachment portion cover protects said the one of the first and second attachment portions from being contaminated, e.g. with dust, dirt or the like, and/or from being manipulated by a tool as mentioned above.

According to another aspect, the object may be achieved by a door lock arrangement for mounting in a door leaf. The door lock arrangement comprises a bolt assembly according to any one of the embodiments and/or examples disclosed herein.

DETAILED DESCRIPTION Figure 1 illustrates a door lock arrangement 1 when installed, or mounted, in a door leaf 2, or door for short.

To the left in Figure 1, illustrating a plan view of the door leaf 2, it is shown that the door lock arrangement 1 comprises a first hub 4 for receiving a lock lever (not shown) and a second hub 6 for receiving a lever handle 8. The door leaf 2 is usually mounted in a door frame via hinges To the right in Figure 1, illustrating a cross-sectional view of the door leaf 2, it is shown that the door leaf 2 may be provided with one handle at each side of the door leaf 2, i.e. a first handle 8a and a second handle 8b.

Turning to Figure 2, a more detailed cross-sectional view of the door lock arrangement 1 is provided. As illustrated, the first hub 4 may be adapted to receive a lock actuator spindle 202 that may be connected to a knob 204 for manually manoeuvring the door lock arrangement. By use of the knob 204, opening and/or closing of the door may be enabled.

Additionally, the second hub 6 is adapted to receive at least one of a first lever handle spindle 206 and a second lever handle spindle 208. ln turn, each of the first and second lever handle spindles 206, 208 may be connected to a respective lever handle, such as the first and second handles 8a, 8b.

Figure 3 shows, in a cross-sectional view and two different perspective views as enumerated from the left to right, an exemplifying door lock arrangement 1 according to some embodiments herein. The exemplifying door lock arrangement 1 includes all aspects disclosed herein for reasons of simplicity. lt shall, however, be understood that the aspects disclosed herein may be implemented separately. Accordingly, there may be provided other door lock arrangements that include any one or more of the aspects of the present invention.

Generally, with reference to the cross-sectional view of Figure 3, the door lock arrangement 1 for mounting in the door leaf 2 comprises a faceplate 10 mountable in the door leaf 2, and a mounting plate 12 adapted to be received by the door leaf 2. The faceplate 10 comprises a first opening 52 adapted to receive an auxiliary latch bolt and a second opening 54 adapted to receive a bolt 18. The faceplate 10 and the mounting plate 12 forms a casing The casing 14 comprises a rotatable gear arm 16 adapted to translationally displace the bolt 18 by rotation about a rotational axis 20 perpendicular to the mounting plate 12. The bolt 18 may be a latch bolt, a dead bolt or the like depending on realization of the door lock arrangement 1. lt is well known that some door lock arrangements include one or more bolts selected from a group comprising at least a latch bolt, a dead bolt and the like.

Moreover, the casing 14 comprises a lock hub 22 adapted to receive a lock actuator spindle 202 for manoeuvring the bolt 18. The lock hub 22 may typically connect to a knob for manually displacing the bolt 18, whereby opening of the door is possible in case being closed in the first place.

The casing 14 further comprises a hub arrangement 24 adapted to allow the bolt 18 to be controlled by actuation of a lever handle spindle, such as the first and second lever handle spindles 206, 208 as shown in Figure 2. The lever handle spindle may have a square cross-section. Therefore, the hub arrangement 24 may be a square hub arrangement.

The hub arrangement 24 may comprise a rower 25 adapted to receive the lever handle spindle, and a lever hub 29 adapted to at least partially enclose and receive the rower 25. ln order to cooperate well with the hub arrangement 24 the rower may comprise a square-shaped cavity for receiving the lever handle spindle.

Figure 4a and Figure 4b shown an exemplifying bolt assembly when mounted in a door lock arrangement 1, e.g. a door lock arrangement 1 for mounting in a door leaf 2 as shown above. The door lock arrangement 1 comprises a bolt assembly according to any one of the exemplifying embodiments illustrated herein with reference to Figure 4 through Figure The bolt assembly 1500, shown in more detailed with reference to Figure 5 below, is adapted to attach a bolt 18 of the door lock arrangement 1. Figure 4a 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. Oppositely, Figure 4b 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. Further, ”classic” positioning may be referred to as a second 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. Generally, 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. When the door lock assembly 1 is mounted in a door, which is mounted in a suitable door frame, 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. Further, 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 Furthermore, the bolt assembly 1500 comprises a bolt guiding member 1509, having a first attachment portion 1502 for releasable attachment of the bolt 18 to the bolt guiding memberand being arranged to translationally guide the bolt 18 along a geometrical axis 63 that is perpendicular to a main plane 60 of the faceplate 10 for extraction and retraction of the bolt 18 relatively the faceplate 10, when the bolt guiding member 1509 is mounted in the door lock arrangement 1. The first attachment portion 1502 may thus enable adaption of the bolt assembly to ”classic” positioning.

Moreover, the bolt guiding member 1509 has a second attachment portion 1504 for releasable attachment of the bolt 18 to the bolt guiding member 1509. The second attachment portion 1504 is offset the first attachment portion 1502 along a longitudinal axis 62 of the faceplate 10 when the bolt guiding member 1509 is mounted in the door lock arrangement 1. The second attachment portion 1504 may thus enable adaption of the bolt assembly to ”modern” positioning.

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. ln this manner, 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 7c) 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 Additionally, the bolt guiding member 1509 may guide the bolt 18 between an extracted position and a retracted position, wherein the bolt 18 protrudes out of the faceplate 10 in the extracted position, and wherein the bolt 18 is retracted towards an interior of the casing 14 in the retracted position.

According to some embodiments, 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. ln these examples, 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 comprises an opening 1507, which is adapted to allow the extraction and the retraction of the bolt 18 when the bolt 18 is attached to the first attachment portion 1502 and when the cover plate 1506 is mounted 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 ln one example of the cover plate 1506 and/or the faceplate 10 is illustrated in Figure 5a through Figure 5c. ln this example, which is also illustrated in Figure 4a and Figure 4b, 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. E.g. 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. Similarly, e.g. when 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.

Furthermore, the cover plate 1506 is reversibly mountable at the faceplate 10. The opening 1507 is offset along the longitudinal axis 62 of the faceplate relatively a center 1501 in the longitudinal direction 1505 of the cover plate 1506 when the cover plate 1506 is mounted at the faceplate 10. The center is thus located at a middle point of the cover plate 1506 when considering distance to distal ends in the longitudinal direction 1505 of the cover plate 1506. A length of the offset is adapted to allow the bolt 18 to be alternatingly mounted at the first and second attachment portions 1502, 1504 upon reversed re-mounting of the cover plate "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.

As an example, the cover plate may thus be mountable in the faceplate 10 in a first mode and a second mode as illustrated in Figure 4a and Figure 4b, respectively.

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. The cover plate 1506 may thus be reversibly mountable to assume the first mode or the second mode, e.g. to switch from the first mode to the second mode or to switch from the second mode to the first mode.

Furthermore, Figure 5c illustrates the first attachment portion 1502 and the second attachment portion 1504. One or more of the first and second attachment portions 1502, 1504 may be a hole, a cavity, a socket, an outlet or the like. Typically, one or more of the first and second attachment portions 1502, 1504 have a bottom, but through-hole or the like is also conceivable depending on use case. A cross-section of the first and/or second attachment portions 1502, 1504, taken perpendicularly to a longitudinal direction thereof, may be circular, rectangular, square, triangular, polygonal or the like. Inner walls of the first and second attachment portions 1502, 1504 are typically smooth, such as even, flat or the like. ln some examples, the inner walls may be threaded. ln general, the first and second attachment portions 1502, 1504 may be adapted to, or configured to, receive the bolt 18, in particular the portion 1710, such as a protrusion, of the bolt 18 as shown in Figure 7d. The recess 1508, shown in Figure 5b, may be adapted to snugly fit, such as formfit with or the like, a shape of the cover plate 1506. As an example, the recess 1508 has a geometric shape that is defined by the cover plate As shown in Figure 5a to Figure 5c, the bolt assembly 1500 comprises the bolt guiding member 1509. ln some examples, the bolt assembly 1500 further comprises an embodiment of the faceplate 10 and an embodiment of the cover plate Figure 6 illustrates an exemplifying bolt assembly 1500 relatively a door lock arrangement 1 in which the exemplifying bolt assembly 1500 is mountable. ln this Figure, two screw holes 1601, 1602 and corresponding screw 1603, 1604 for mounting of the cover plate 1506 at the faceplateare shown.

Figure 7a through Figure 7e include side views and a cross-sectional view of an exemplifying bolt assembly.

Figure 7a shows the first and second attachment portions 1502, 1504 inside the guiding member 1509. Moreover, the bolt 18 is shown as mounted for ”modern” positioning, i.e. mounted in the second attachment portion Figure 7b shows that the first attachment portion 1502 may be vacant, in case the bolt 18 is mounted in the second attachment portion Figure 7c 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 7e, in one or the other of the first and second attachment portions 1502, 1504. ln this example, the bolt 18 is mounted at the second attachment portion 1504 by means of the screw Figure 7d illustrates a top view of the bolt guiding member 1509 and the bolt 18. A cross- sectional view across a plane A is illustrated in Figure 7e. ln Figure 7d, it may be seen that a portion of the bolt 18 is adapted to be received by and inserted into the bolt guiding member 1509, preferably by a tight fit, snug fit or the like. The portion may be referred to as a protrusion 1710. At adistal end of the protrusion 1710 a heel 1712, or shoulder, is located in order to prevent the bolt 18 from sliding out of the first or second attachment portion1502, 1504, should the screw 1702, 1704 not be tightened sufficiently.

Figure 7e shows the aforementioned cross-sectional view in the plane A. The bolt guiding member 1509 is provided with two screw holes 1706, 1708, one for each of the first and second attachment portions 1502, 1504 as mentioned above. The two screw holes 1706, 1708 may have a respective threaded inner surface. The screw holes 1706, 1708 penetrate through the bolt guiding member 1509 from an interior of the first and second attachment portions 1502, 1504 to a side surface 1720 of the bolt guiding member 1509. The side surface 1720 is shown in Figure 7c.

Figure 8a and Figure 8b illustrates an exemplifying cover plate 1506 and an exemplifying faceplate 10 of an exemplifying bolt assembly ln this example, the faceplate 10 is arranged to allow mounting of the cover plate 1506 at a first location 1802 and a second location 1804, e.g. within the recess 1508. This may be achieved by that a recess length 1806 of the recess 1508, e.g. in the longitudinal direction of the faceplate 10, is greater than a cover plate length 1808 of the cover plate 1506. The first location 1802 and the second location 1804 may be given with reference to one of two distal ends 1811, 1812 of the faceplate 10, e.g. distal in the longitudinal direction of the faceplate. Other ways of defining the first and second location 1802, 1804 are also possible, e.g. in terms of distance from a distal end of the recess 1508. A difference between the recess length 1806 and the cover plate length 1808 is given by a difference in positions of the bolt 18 for ”classic” and ”modern” positioning, respectively. ln embodiments, including the recess 1508 and the cover plate 1506, it is preferred that a depth of the recess 1508 is equal to, or approximately equal to, a depth of the cover plate 1506. ln this context, these depths are measured along the geometrical axis 63, e.g. when the cover plate 1506 is mounted at the faceplate 10. The first location 1802 is offset the second location 1804 along the longitudinal axis 62 of the faceplate 10. As exemplified above, a distance between the first and second locations 1802, 1804 may be given by the difference in positions of the bolt 18 for ”classic” and ”modern” positioning.

As an example, the faceplate 10 may be provided with a first set of screw holes 1821, 1822 and a second set of screw holes 1823, 1824. The first set of screw holes 1821, 1822 is offset the second set of screw holes 1823, 1824 along the longitudinal axis 62, e.g. according to the difference in positions of the bolt 18 for ”classic” and ”modern” positioning as mentioned above.

Figure 9a and Figure 9b are plan views illustrating another exemplifying bolt assembly. ln one example, while disregarding the dotted lines, there is provided a first faceplate 10aand a second faceplate 10b for each of the ”classic” and ”modern” positioning of the bolt 18. This is thus in contrast to the examples of Figure 6, Figure 8a and Figure 8b, where the same faceplate 10 is used for both ”classic” and ”modern” positioning of the bolt 18. This kind of specially adapted faceplates 10a, 10b are known in the art. ln this example, the bolt guiding member 1509 having the first and second attachment portions 1502, 1504, alone provides for at least some of the advantages mentioned herein.

However, in one example - now considering the dotted cover plates 1506a, 1506b in Figure 9a and Figure 9b -it may be that one and the same faceplate 10 is used for door lock arrangements adapted to either ”classic” and ”modern” positioning of the bolt 18. Such faceplate 10 may typically have a faceplate recess 1901 that fits closely to a peripheral contour of the cover plate 1506a as well as a peripheral contour of the cover plate 1506b. The depths of the faceplate recess 1901 is matched to thickness of the cover plate 1506a, 1506b. ln Figure 9a, a first cover plate 1506a has an opening 1507, whose position in the longitudinal direction of the first cover plate 1506a is chosen such that the bolt 18 is extractable and retractable though the opening 1507 when the bolt 18 is mounted in the first bolt attachment portion 1502. This means that the first cover plate 1506a is adapted to ”classic” positioning of the bolt ln Figure 9b, a second cover plate 1506b has an opening 1507, whose position in the longitudinal direction of the second cover plate 1506b is chosen such that the bolt 18 is extractable and retractable though the opening 1507 when the bolt 18 is mounted in the second bolt attachment portion 1504. This means that the second cover plate 1506b is adapted to ”modern” positioning of the bolt The cover plate 1506 is thus exemplified by the first and second cover plates 1506a, 1506b, which may be considered to be different versions of the cover plate 1506, one version for ”classic” and another version for "modern".

With reference to the embodiment indicated by the dashed lines in Figure 9a and Figure 9b, the cover plate 1506, according to some embodiments, is non-reversibly mountable at the faceplate 10. The opening 1507 is offset along the longitudinal axis 62 of the faceplate 10 relatively an end 1902 of the faceplate 10, previously referred to as the distal end 1812. A length of the offset is adapted to allow the bolt 18 to be mounted at the first or second attachment portions 1502,and also e.g. extractable and retractable through the opening As described above, a purpose of the different embodiments of the cover plate 1506 is to protect the one of the first and second attachment portions 1502, 1504 in which the bolt 18 is not installed, or mounted. Said one of the first and second attachment portions 1502, 1504 may hence be protected from being contaminated with dirt, dust or debris of any kind that may obscure normaloperation of the door look assembly 1. Moreover, the door lock assembly 1 is protected, at least to some extent, from being tampered with, e.g. thanks to that said one of the first and second attachment portions 1502, 1504 is not accessible with a tool, such as a picklock or the like.

Figure 10a and Figure 10b are perspective views illustrating details of a still further exemplifying bolt assembly. With this embodiment, said one of the first and second attachment portions 1502, 1504 is at least protected from dirty, but it may also, at least to some extent - though possibly less than in the previously disclosed embodiments, protect against tampering or the like.

Hence, in some embodiments, the bolt assembly 1500 further comprises an attachment portion cover 2002 adapted to be releasably mountable at the first and second attachment portion 1502, 1504 alternatingly. As an example, the attachment portion cover 2002 is thus mounted in said one of the first and second attachment portions 1502, 1504. ln these embodiments, two screws 1702, 1704 may be required. ln some examples, the attachment portion cover 2002 may be integrated with the bolt 18. ln case the bolt 18 is asymmetric with reference to the secondary plane 61, see Figure 3, it may be that there is one bolt including attachment portion cover for the ”classic” positioning and another bolt including attachment portion for the ”modern” positioning. Since the attachment portion cover 2002 is integrated with the bolt 18 only one screw 1702, 1703 may be required.

The attachment portion cover 2002 is further adapted to present a flat surface 2004 facing away from the bolt guiding member 1509 when mounted in the first or second attachment portion 1502, 1504. The flat surface 2004 may be aligned with the faceplate 10 when the bolt 18 is extracted, e.g. completely extracted.

Alternatively, with embodiments including the cover plate, the flat surface 2004 may be aligned with a bolt guiding member surface 2010 of the bolt guiding member. The bolt guiding member surface 2010 faces the face plate 10 when the bolt assembly 1500 is used, or mounted, together with a door lock arrangement As used herein, the term "bias", "biased", "biasing" or the like may refer to mechanical biasing by means of a spring, a plate spring or the like.

As used herein, the term ”along an axis" may refer to parallelly with the axis and/or coinciding with the axis.

Each embodiment, example or feature disclosed herein may, when physically possible, be combined with one or more other embodiments, examples, or features disclosed herein.

Even though embodiments of the various aspects have been described above, many different alterations, modifications and the like thereof will become apparent for those skilled in the art. The described embodiments are therefore not intended to limit the scope of the present disclosure.
