Description

[0001] ARRANGEMENT FOR LOCK DEVICE, AND LOCK DEVICE COMPRISING ARRANGEMENT

[0002] Technical Field

[0003] The present disclosure generally relates to an arrangement for a lock device. In particular, an arrangement for a lock device comprising first and second deadlocking features for deadlocking a deadbolt, and a lock device comprising such arrangement, are provided.

[0004] Background

[0005] Some lock devices comprise a deadbolt movable between a retracted position and an extended position. For example, rotation of a thumb turn may rotationally drive an actuating member which in turn drives the deadbolt. The lock device can be integrated in a door leaf rotatable relative to a frame and the deadbolt can engage a strike opening in the frame when the door leaf is closed and the deadbolt is in the extended position.

[0006] In some lock devices of the above type, the actuating member is provided with a deadlocking feature in which the deadbolt is seated when the actuating member is rotated into an extended actuating position and the deadbolt is in the extended position. Should the deadbolt be tampered with and pushed towards the retracted position in this state of the lock device, the deadlocking feature will prevent the deadbolt from leaving the extended position.

[0007] Summary

[0008] In many lock devices of the above type, the deadbolt may not always reach the extended position. Reasons for this may include that the strike opening is incorrectly dimensioned, that a foreign object has entered the strike opening, or that a user has not rotated the thumb turn sufficiently. Regardless of the reason, the deadbolt may then be positioned in an offset position close to theextended position but between the retracted position and the extended position. If a force is exerted on the deadbolt towards the retracted position while being in the offset position, the deadbolt can be forced to retract to the retracted position. Since the offset position may be very close to the extended position, a sensor for distinguishing between the deadbolt being in the extended position and in the offset position may need a quite high resolution. If not, there is a risk that such lock device enters a state where the sensor informs that the deadbolt is locked, when it is not.

[0009] One object of the invention is to provide an improved arrangement for a lock device.

[0010] This object is achieved by the arrangement according to appended claim 1.

[0011] The invention is based on the realization that by providing an arrangement for a lock device comprising a deadbolt, an actuating member, a first deadlocking feature for deadlocking the deadbolt in an extended position and a second deadlocking feature for deadlocking the deadbolt in an intermediate position should the deadbolt fail to reach the extended position, the arrangement can be made more secure while also enabling a use of sensorics of lower resolution.

[0012] According to a first aspect, there is provided an arrangement for a lock device, the arrangement comprising a base structure; a deadbolt movable relative to the base structure between a retracted position for disengagement from a strike opening of a strike and an extended position for engagement with the strike opening; an actuating member arranged to rotate relative to the base structure around an actuating member axis from a retracted actuating position to an extended actuating position to thereby cause the deadbolt to move from the retracted position to the extended position; a first deadlocking feature arranged to deadlock the deadbolt in the extended position when the actuating member is in the extended actuating position; and a second deadlocking feature arranged to deadlock the deadbolt in an intermediate position between the retracted position and the extendedposition when the actuating member is in an intermediate actuating position between the retracted actuating position and the extended actuating position.

[0013] The arrangement thus provides an extended position where the deadbolt is locked and fully extended, and an intermediate position where the deadbolt is locked but not fully extended. This is advantageous for several reasons.

[0014] Should the deadbolt fail to reach the extended position and only reach a position close to the extended position beyond the intermediate position, the deadbolt will in any case be locked, e.g., at least by the second deadlocking feature. Furthermore, since the deadbolt is in fact locked when positioned at any position beyond the intermediate position, the arrangement enables a sensor of lower resolution to be used to confirm that the deadbolt is locked, e.g., in contrast to a sensor used to distinguish between the deadbolt being in the extended position and in the offset position. The arrangement thus has an improved security, for example with respect to user errors and tampering.

[0015] The arrangement may be configured to transmit a rotation of the actuating member around the actuating member axis to the movement of the deadbolt. This can be realized in numerous ways. The actuating member may act directly or indirectly on the deadbolt. Thus, the actuating member may or may not be arranged to contact the deadbolt. The actuating member may push the deadbolt towards the extended position and / or pull the deadbolt towards the retracted position. In any case, with respect to movements of the deadbolt, the actuating member may be a driving member and the deadbolt may be a driven member driven by the driving member. The retracted actuating position and the extended actuating position of the actuating member correspond to the retracted position and the extended position, respectively, of the deadbolt.

[0016] The deadbolt may comprise a driven surface. In these cases, the actuating member may contact the driven surface to transmit the rotation of the actuating member to the movement of the deadbolt. The driven surface may be arranged in a deadbolt opening receiving the actuating member, such as in the form of an actuating arm thereof.The deadbolt may be movable between the retracted position and the extended position in an actuating direction. The actuating direction may be linear or circular. The deadbolt may be guided by the base structure in the actuating direction. The actuating direction may be transverse to the actuating member axis.

[0017] The deadbolt may protrude out from the base structure in the extended position. The deadbolt may or may not protrude out from the base structure in the retracted position.

[0018] The deadbolt may be structurally integral. To this end, the deadbolt may for example be formed from a single piece of material or may be constituted by a plurality of fixedly connected parts. In the latter case, the deadbolt may for example comprise a bolt part and an extension fixed to the bolt part, as described herein.

[0019] The actuating member may comprise an actuating arm extending from the actuating member axis. The actuating member may comprise a follower and the actuating arm fixed to the follower. The follower may be driven by a thumb turn.

[0020] The base structure may comprise a housing. The deadbolt may be accommodated substantially entirely inside of, or entirely inside of, the housing when adopting the retracted position. The base structure may comprise a forend fixed to the housing. The housing may comprise a tubular body. In this case, the arrangement may be said to constitute a tubular arrangement.

[0021] The arrangement may further comprise an electronic control system. The control system may comprise at least one data processing device and at least one memory having at least one computer program stored therein, the at least one computer program comprising program code which, when executed by the at least one data processing device, causes the at least one data processing device to perform, or command performance of, various operations including the operations as described herein.An intermediate distance between the intermediate position and the extended position may be at least 5 % and / or less than 50 %, such as at least 10 % and / or less than 40 %, of a first distance between the retracted position and the extended position. The larger the intermediate distance is in relation to the first distance, the lower the resolution of the sensor can be.

[0022] The arrangement may further comprise an offset structure between the first deadlocking feature and the second deadlocking feature arranged to engage the deadbolt or the actuating member when the deadbolt is in an offset position between the intermediate position and the extended position and when the actuating member is in an offset actuating position between the intermediate actuating position and the extended actuating position. When this engagement takes place, a retracting force acting on the deadbolt towards the retracted position causes the deadbolt to move from the offset position and be stopped by the second deadlocking feature in the intermediate position. The offset position may be defined as a position of the deadbolt closest to the extended position where this behavior occurs.

[0023] The arrangement may further comprise a sensor configured to provide position information indicative of a position of the deadbolt relative to the base structure. The sensor may be arranged to directly sense a position of the deadbolt along the actuating direction, of the actuating member around the actuating member axis, or of the thumb turn around an input shaft fixed to the thumb turn. The sensor may thus sense the position of the deadbolt directly or indirectly.

[0024] The sensor may be fixed with respect to the base structure and / or arranged inside of the base structure. The sensor may be a switch, such as a binary switch. The switch may for example be mechanical or optical.

[0025] The control system may be configured to receive the position information from the sensor. In these cases, the control system may be configured to determine that the deadbolt engages the strike opening conditional on the deadbolt being in the extended position and that the deadbolt does notengage the strike opening when the deadbolt is in the retracted position. The former determination may for example be conditional on information indicative that a door leaf including the arrangement is closed.

[0026] The sensor may be a switch arranged to be triggered when the deadbolt adopts the retracted position or the extended position.

[0027] A resolution of the sensor may be lower than an offset distance between the offset position and the extended position.

[0028] The sensor may be arranged to be triggered when the deadbolt adopts the retracted position and the intermediate position, but not when adopting the extended position, or vice versa, i.e., when the deadbolt adopts the extended position but not when adopting the retracted position and the intermediate position. In some variants, the sensor is triggered throughout a range of at least 50 %, such as at least 8o %, of the intermediate distance including the extended position, but not outside this range, or vice versa.

[0029] Each of the first deadlocking feature and the second deadlocking feature may be a recess. In case the first and second deadlocking features are provided on the actuating member, each recess may be configured to contact the driven surface. In case the first and second deadlocking features are provided on the deadbolt, each recess may be configured to contact a drive element of the actuating member, e.g., arranged at a distal end of the actuating arm.

[0030] The arrangement may further comprise a cam surface between the first deadlocking feature and the second deadlocking feature. In these cases, the cam surface may be arranged to transmit a rotation of the actuating member towards the extended actuating position to a movement of the deadbolt towards the extended position.

[0031] The first deadlocking feature and the second deadlocking feature may be provided on the actuating member.

[0032] The second deadlocking feature may be positioned between the actuating member axis and the first deadlocking feature.According to a second aspect, there is provided a lock device comprising an arrangement according to the first aspect.

[0046] Detailed Description

[0047] In the following, an arrangement for a lock device comprising first and second deadlocking features for deadlocking a deadbolt, and a lock device comprising such arrangement, will be described. The same or similar reference numerals will be used to denote the same or similar structural features.

[0048] Fig. 1 schematically represents an outer view of an access member system 10. The access member system 10 comprises one example of a lock device 12. The access member system 10 of this example further comprises a frame 14 and a door leaf 16 rotatable relative to the frame 14 around a vertical axis 18. The door leaf 16 is one example of an access member according to the present disclosure. The lock device 12 is installed in the door leaf 16. In Fig. 1, the door leaf 16 is in the frame 14 in a closed position. Fig. 1 further shows a gap 20 between the door leaf 16 and the frame 14.

[0049] The access member system 10 further comprises an outer handle 22a, an inner handle 22b (Fig. 3) and a latch bolt 24. Each of the outer and inner handles 22a, 22b can be operated to retract the latch bolt 24.

[0050] The lock device 12 comprises an arrangement 26a. The arrangement 26a comprises a deadbolt 28a. The deadbolt 28a of this example is linearly movable in an actuating direction 30.

[0051] The lock device 12 of this example further comprises an outer escutcheon 32a, an inner escutcheon 32b (Fig. 3), an outer thumb turn 34a arranged at the outer escutcheon 32a, and an inner thumb turn 34b (Fig. 3) arranged at the inner escutcheon 32b.The access member system io of this example further comprises a strike 36. The strike 36 is installed in the frame 14. In Fig. 1, the deadbolt 28a is in an extended position 38 engaging a strike opening of the strike 36.

[0052] Fig. 2 schematically represents a front view of the strike 36. In Fig. 2, the strike opening 40 of the strike 36 can be seen. Fig. 2 also shows that the strike 36 of this example also comprises a latch opening 42 for receiving the latch bolt 24.

[0053] Fig. 3 schematically represents a front view of the lock device 12. The outer thumb turn 34a and the outer escutcheon 32a are arranged at an outside 44a of the door leaf 16. The inner thumb turn 34b and the inner escutcheon 32b are arranged at an inside 44b of the door leaf 16.

[0054] The lock device 12 comprises a forend 46, an outer input shaft 48a (illustrated with solid lines) fixed to the outer thumb turn 34a and an inner input shaft 48b (illustrated with dashed lines) fixed to the inner thumb turn 34b. In this example, the inner input shaft 48b is permanently operatively connected to the deadbolt 28a such that the deadbolt 28a can always be retracted from the inside 44b of the door leaf 16 by turning the inner thumb turn 34b.

[0055] The lock device 12 of this example further comprises a coupling 50. The coupling 50 is configured to selectively operatively couple the outer thumb turn 34a to the deadbolt 28a. To this end, the coupling 50 of this example is configured to selectively operatively connect the outer input shaft 48a and the inner input shaft 48b. When the outer thumb turn 34a is operatively connected to the deadbolt 28a, the deadbolt 28a can be operated via the coupling 50 by turning the outer thumb turn 34a. The coupling 50 may for example be activated to operatively couple the outer thumb turn 34a and the deadbolt 28a conditional on presenting a valid credential, e.g., wirelessly using an RFID (Radio Frequency Identification) card. If no credential is presented or if no valid credential is presented, the outer thumb turn 34a can be rotated freely and the outer input shaft 48a may be said to freewheel.Fig. 4 schematically represents a perspective side view of the arrangement 26a. In addition to the deadbolt 28a, the arrangement 26a comprises a base structure 52 and an actuating member 54a. The deadbolt 28a is movable relative to the base structure 52 in the actuating direction 30.

[0056] The actuating member 54a is rotatable relative to the base structure 52 around an actuating member axis 56. The actuating member axis 56 is here transverse to the actuating direction 30. The actuating member 54a of this example comprises a follower 58 concentric with the actuating member axis 56 and an actuating arm 60 extending from the follower 58 transverse to the actuating member axis 56. The follower 58 may for example be engaged by, and rotate in common with, the inner input shaft 48b. The outer input shaft 48a may here pass through the follower 58 within the inner input shaft 48b.

[0057] Fig. 4 further shows that the arrangement 26a comprises a first deadlocking feature 62a and a second deadlocking feature 64a, in this example both arranged on the actuating member 54a. Each of the first and second deadlocking features 62a, 64a is here exemplified as a recess in the actuating arm 60. The second deadlocking feature 64a is positioned between the actuating member axis 56 and the first deadlocking feature 62a. The actuating member 54a of this example further comprises a cam surface 66a positioned between the first and second deadlocking features 62a, 64a.

[0058] The arrangement 26a is configured to transmit a rotation of the actuating member 54a around the actuating member axis 56 in a first direction (clockwise in Fig. 4) to a movement of the deadbolt 28a from a retracted position 68 (Fig. 8) to the extended position 38, and to transmit a rotation of the actuating member 54a around the actuating member axis 56 in a second direction (counterclockwise in Fig. 4), opposite to the first direction, to a movement of the deadbolt 28a from the extended position 38 to the retracted position 68. To this end, the deadbolt 28a of this example comprises a deadbolt opening 70a receiving, and being engaged by, the actuating arm 60.The arrangement 26a of this example further comprises a sensor 72. The sensor 72 is configured to provide deadbolt position information indicative of a position of the deadbolt 28a relative to the base structure 52. To this end, the sensor 72 of this example is configured to directly sense a position of the deadbolt 28a in the actuating direction 30 relative to the base structure 52. The sensor 72 of this example is a mechanical binary switch and is fixed to the base structure 52 inside of the base structure 52. The sensor 72 may alternatively be configured to sense a position of the actuating member 54a around the actuating member axis 56, or a position of any of the outer and inner thumb turns 34a, 34b (e.g., via any of the outer and inner input shafts 48a, 48b), for an indirect determination of the position of the deadbolt 28a.

[0059] The base structure 52 of this example comprises a housing in the form of a tubular body 74 and the forend 46 fixed at a front of the tubular body 74. In the extended position 38, the deadbolt 28a protrudes out from the base structure 52, here through a base structure opening 76 of the forend 46. The forend 46 of this example comprises two mounting holes 78 for securing the base structure 52 to the door leaf 16.

[0060] The deadbolt 28a travels inside of the tubular body 74. The deadbolt 28a comprises a distal end 80. The distal end 80 includes a surface substantially transverse to the actuating direction 30.

[0061] Fig. 5 schematically represents a side view of the actuating member 54a. In Fig. 5, the geometry of the actuating member 54a according to this example is more clearly shown. Fig. 5 further shows that the actuating member 54a comprises an offset structure 82a between the first and second deadlocking features 62a, 64a, here between the first deadlocking feature 62a and the cam surface 66a. The offset structure 82a is here exemplified as an edge parallel with the actuating member axis 56. The actuating member 54a of this example further comprises a spring feature 84.

[0062] Fig. 6 schematically represents a perspective rear view of the deadbolt 28a. The deadbolt 28a of this example is structurally integral and comprises a boltpart 86 for engaging the strike opening 40, and an extension 88 fixed to the bolt part 86. As shown, the deadbolt opening 70a of this example comprises a driven surface 90. The driven surface 90 of this specific example is a planar surface oriented transverse to the actuating direction 30. Moreover, the driven surface 90 of this example is provided in the extension 88.

[0063] Fig. 7 is a block diagram schematically representing parts of the arrangement 26a. As shown in Fig. 7, the deadbolt 28a is movable from the retracted position 68 to the extended position 38 in the actuating direction 30. Fig. 7 further shows an intermediate position 92 that the deadbolt 28a can adopt. As explained herein, the extended position 38 and the intermediate position 92 correspond to the first deadlocking feature 62a and the second deadlocking feature 64a, respectively.

[0064] Fig. 7 further shows a first distance 94 defined from the retracted position 68 to the extended position 38, and an intermediate distance 96 defined from the intermediate position 92 to the extended position 38. The first distance 94 may for example be 25 mm. The intermediate distance 96 may for example be at least 5 % and / or less than 50 %, of the first distance 94, such as 10 mm.

[0065] The arrangement 26a of this example further comprises an electronic control system 98. The control system 98 of this example comprises a data processing device 100 and a memory 102. The memory 102 has a computer program stored thereon. The computer program comprises program code which, when executed by the data processing device 100, causes the data processing device 100 to perform, or command performance of, various operations as described herein.

[0066] The control system 98 of this example further comprises an antenna 104 for wirelessly receiving a credential, e.g., from an RFID card (not shown) presented by a user at the outside 44a of the door leaf 16. The control system 98 is configured to evaluate the credential. Conditional on the credential being valid, the control system 98 commands actuation of the coupling 50.The sensor 72 is arranged to send position information 106 to the control system 98. The sensor 72 of this example is a binary switch that is triggered by the deadbolt 28a, such as by a protrusion 108 on the deadbolt 28a, when the deadbolt 28a adopts any position beyond the intermediate position 92 and within a range 110, including the extended position 38. Thus, the sensor 72 sends a signal to the control system 98 when the deadbolt 28a is within the range 110, such as in the extended position 38, but not when the deadbolt 28a is in any of the intermediate position 92 and the retracted position 68 or in any position therebetween. Both the signal and the absence of the signal constitute examples of the position information 106. The range 110 may for example be 90 % of the intermediate distance 96.

[0067] Alternatively, the sensor 72 may be triggered and send a signal to the control system 98 when the deadbolt 28a is in the retracted position 68, in the intermediate position 92 or in any position therebetween, but not when the deadbolt 28a is in the extended position 38, i.e., triggered within the first distance 94 but outside of the range 110.

[0068] Fig. 8 schematically represents a partial cross-sectional side view of the arrangement 26a when the actuating member 54a is in a retracted actuating position 112 and the deadbolt 28a is in the retracted position 68. In the retracted position 68, the distal end 80 is aligned with a front surface of the forend 46 in this example.

[0069] Fig. 8 further shows that the arrangement 26a of this example comprises an actuating member spring 114. The actuating member spring 114 forces the actuating member 54a into the retracted actuating position 112, here by acting on the spring feature 84. The actuating member spring 114 of this example is a blade spring.

[0070] Fig. 9 schematically represents a partial cross-sectional side view of the arrangement 26a when the actuating member 54a is in a extended actuating position 116, the deadbolt 28a is in the extended position 38 and the firstdeadlocking feature 62a thereby contacts the driven surface 90, here such that the driven surface 90 is seated in the first deadlocking feature 62a.

[0071] The arrangement 26a is arranged to transmit a rotation of the actuating member 54a around the actuating member axis 56 from the retracted actuating position 112 to the extended actuating position 116 to a movement of the deadbolt 28a from the retracted position 68 to the extended position 38 in the actuating direction 30, here by the actuating member 54a contacting and pushing the deadbolt 28a. During a part of the rotation of the actuating member 54a from the retracted actuating position 112 to the extended actuating position 116, the cam surface 66a contacts the driven surface 90 and drives the deadbolt 28a towards the extended position 38. This rotation of the actuating member 54a also occurs against a force from the actuating member spring 114. In the extended actuating position 116, the actuating member spring 114 now forces the actuating member 54a into the extended actuating position 116, here by acting on the spring feature 84.

[0072] Due to the first deadlocking feature 62a contacting the driven surface 90, the deadbolt 28a is deadlocked in the extended position 38. If a force is applied to the deadbolt 28a towards the retracted position 68, e.g., by using a tool through the gap 20, the engagement between the deadbolt 28a and the first deadlocking feature 62a will cause the deadbolt 28a to be slightly angled and pressed against the base structure 52 to thereby restrict movement of the deadbolt 28a away from the extended position 38.

[0073] Fig. 10 schematically represents a partial cross-sectional side view of the arrangement 26a when the actuating member 54a is in an offset actuating position 118 and the deadbolt 28a is in an offset position 120. In the offset position 120, the deadbolt 28a is not fully thrown and is hence offset from the extended position 38, for example due to an incorrectly dimensioned strike opening 40, due to a foreign object in the strike opening 40, or due to a user not having rotated any of the thumb turns outer and inner thumb turns 34a, 34b fully.Fig. io shows an offset distance 122 defined between the offset position 120 and the extended position 38. When the actuating member 54a is in the offset actuating position 118 and the deadbolt 28a is in the offset position 120, the offset structure 82a engages the driven surface 90. Should the arrangement 26a not comprise the second deadlocking feature 64a, there would be a risk that the deadbolt 28a could be manipulated from the offset position 120 to the retracted position 68 by exerting a retracting force on the deadbolt 28a.

[0074] Fig. 11 schematically represents a partial cross-sectional side view of the arrangement 26a when the actuating member 54a is in an intermediate actuating position 124, the deadbolt 28a is in the intermediate position 92 and the second deadlocking feature 64a thereby contacts the driven surface 90, here such that the driven surface 90 is seated in the second deadlocking feature 64a. When a retracting force acts on the deadbolt 28a when the deadbolt 28a is in the offset position 120, the deadbolt 28a will move from the offset position 120 to the intermediate position 92 where the deadbolt 28a is stopped and deadlocked by the second deadlocking feature 64a. When the deadbolt 28a is in the intermediate position 92, the sensor 72 is not triggered. Thus, although the deadbolt 28a is locked in the intermediate position 92 by the second deadlocking feature 64a, the sensor 72 signals the deadbolt 28a as being unlocked. In this way, a situation where the deadbolt 28a is not fully thrown and stops in the offset position 120 can be securely handled. Moreover, since the intermediate distance 96 is substantially larger than the offset distance 122, e.g., at least five times as large, the resolution of the sensor 72 can be reduced, e.g., to be substantially lower than the offset distance 122, and hence less costly.

[0075] Fig. 12 schematically represents a partial cross-sectional side view of an arrangement 26b according to a further example. Mainly differences with respect to the arrangement 26a will be described. The arrangement 26b comprises an actuating member 54b including a drive element 126, here arranged at a distal end of the actuating arm 60. The arrangement 26b further comprises a deadbolt 28b including a deadbolt opening 70b, here exemplified as a slot. The deadbolt opening 70b comprises a first deadlockingfeature 62b, an offset structure 82b, a cam surface 66b and a second deadlocking feature 64b. In Fig. 12, the actuating member 54b is in the retracted actuating position 112, the deadbolt 28b is in the retracted position 68 and the drive element 126 engages the deadbolt opening 70b.
