Description

Description [0001] The present invention relates to a lock, in particular to a pivoting dead bolt lock, which comprises a lock housing, in which at least one locking mechanism with a dead bolt is accommodated. The dead bolt can be moved into a locking position, in which the former protrudes from the lock housing for locking the door, wherein the dead bolt can be transferred into an opening position, in which the dead bolt can be moved back into the lock housing for opening the door. The locking mechanism comprises two activating elements, which can be activated via an activation movement for moving the dead bolt. The operative connection between the activating elements and the dead bolt comprises a gearing element, wherein at least one blocking member is provided for a securing blocking of the locking mechanism, which member can be transferred into a blocking position and into a release position. In the blocking position, the blocking member is in engagement with the gearing element, wherein in the release position, the blocking member is disposed to be detached from the gearing element.

[0002] A lock of this species is already known from the document DE 10 2008 016 699.5-15, which is configured as a pivoting dead bolt lock. Such a lock finds its application in doors, gates or for example windows. The dead bolt is configured as a hook dead bolt and is accommodated in the lock housing to be pivotable. In the event the dead bolt is pivoted out of the lock housing, and protrudes from the housing, the dead bolt can latch with a counter-element, which is configured to be complementary, with the purpose of locking the door, the gate or for example the window. In the event the lock is unlocked, for example by means of a handle or by means of a locking cylinder, the dead bolt can be transferred from the locking position into the opening position. In this case, the activating element is formed for activating the locking mechanism and consequently for moving the dead bolt, for example by means of a handle, such as a door knob, a door handle, and furthermore by means of a locking cylinder.

[0003] A lock, which is embodied as a pivoting dead bolt lock, is likewise known from the document US 4,127,016 Al. The lock includes two activating elements, which are able to continuously act upon the locking mechanism for moving the dead bolt between an opening position and a locking position. In this case, the dead bolt in the locking position may protrude from the lock housing for locking the door, and in the opening position, the dead bolt can be moved back into the lock housing for opening the door.

[0004] A lock, which is embodied for sliding doors or windows, is known from the document US 2006/130543 Al. The lock includes two pivoting dead bolts, which are disposed to be rotatably supported in the lock housing, and are driven via toothed rods, which are linearly guided in the lock housing, as long as a rotary movement is introduced into the locking mechanism via the locking cylinder.

[0005] In such locks, the opening in the frontal building area of the lock housing represents reduced safety, because, on account of the pivotability of the dead bolt, the opening has to be configured correspondingly large. In the event the dead bolt needs to be pivoted out of the lock housing, the locking mechanism may be potentially overcome with a burglary tool in that a transfer of the dead bolt from the locking position into the opening position may be enabled without activation of one of the activating elements.

[0006] Figure 1 shows a lock 1 of this species according to the state-of-the-art. The lock 1 comprises a lock housing 2, in which the dead bolt 3 is configured to be pivotable about a dead bolt shaft 27. The gearing element 6, which is articulately connected to the dead bolt 3 via the bolt 25, is shown for articulating the dead bolt 3, wherein the bolt 25 is guided in a guiding coulisse 26, which is machined into the dead bolt 3. In the event the gearing element 6 is rotated clockwise about the rotation axis 8, the dead bolt may be transferred from the opening position shown into the locking position.

[0007] In this case, the rotation of the gearing element 6 about the rotation axis 8 is triggered either by means of a first activating element, formed by means of the follower 4, or a second activating element, formed by the catch 5. The catch 5 serves as a catch for a locking cylinder, which is able to entrain the catch 5 into a rotary movement. Via the toothed structure 17, which meshes in the first toothed crown 24 of the gearing element 6, the rotary movement of the catch 5 can be transferred onto a rotary movement of the gearing element 6, [0008] In the event the locking mechanism is activated via the follower 4, the latter is rotated about the follower axis 12. A lever element 15, which is able in the same manner to produce a rotary movement in the gearing element 6 via a toothing and consequently a pivoting movement in the dead bolt 3, is affixed to the follower 4.

[0009] At the frontal side the lock has a faceplate 28, into which an opening, which is not shown in detail, is machined. Furthermore, a dead-centre line 31 is shown, which is determined by means of the axis of rotation 8 and the dead bolt shaft 27 in the direction of extension. In the illustrated opening position of the dead bolt 3, the bolt 25 is located below the dead-centre line 31. In the event the dead bolt 3 is transferred into the locking position, the bolt 25 travels over the dead-centre line 31 and remains on the upper side of the dead-centre line 31. Initially, a stable position of the dead bolt 3 in the locking position is thereby created, wherein said position is in particular ensured by means of spring elements, which are not illustrated in detail. In the event the dead bolt 3 would be forcibly rotated about the dead bolt shaft 27, on account of the arrangement of the bolt 25, a counter-moment is created above the dead-centre line 31, which moment prevents the dead bolt 3 from being transferred from the locking position into the opening position [0010] However, disadvantageously it has proven that, by manual action on the locking mechanism, nevertheless a transfer of the dead bolt 3 from the locking position into the opening position is still possible. In particular through the opening in the faceplate 28, a counter-clockwise rotary movement can be initiated into the gearing element 6 with a burglary tool, such that at least the bolt 25 is brought below the dead-centre line 31. Thereby, no other counter-moment can be maintained, if the dead bolt 3 is forcibly transferred into the opening position. With the intention to prevent this from happening, just the locking cylinder may remain in a blocking position, such that a movement of the gearing element 6 via the toothing of the toothed structure 17 with the first toothed crown 24 of the gearing element 6 prevents a rotation. However, said blocking, which acts as a guard locking, by means of the locking cylinder does not provide satisfactory safety against manual burglary attempts of a forced opening of the lock 1.

[0011] Even though such locks are embodied with blocking members, which may directly act upon the dead bolt, likewise said blocking members can not be embodied completely safe. Such blocking members, which are in particular referred to as guard locking, are often formed by means of particular kinematic arrangements of the locking mechanism itself, which arrangements however are easily reachable through the opening in the faceplate of the lock housing and can be likewise overcome.

[0012] Therefore, it is the object of the present invention to provide a lock according to the present species having increased safety against manual burglary attempts.

[0013] This problem is solved based on a lock according to the generic part of claim 1 in conjunction with the characterizing features. Advantageous further developments of the invention are indicated in the dependent claims.

[0014] The invention includes the technical teaching that an activating element, which is embodied as a catch, is accommodated to be rotatable about a catch axis in the lock housing and has a toothed structure, which can be brought into operative connection with the blocking member in such a way that, upon rotation of the catch, a transfer of the blocking member into the release position is enabled, and in that a pressure member is accommodated to be mobile about a pressure member axis in the lock housing and disposed in such a way that the toothed structure can be brought against a pressure surface provided at the pressure member at least via the portion of the activating movement sequentially preceding the activation of the movement of the dead bolt, such that the pressure member performs a movement, which can be transferred onto the blocking member via a catch arrangement.

[0015] A change between the blocking position and the release position of the blocking member at least via a portion of the activation movement of each activating element can be produced in such a way that a movement of the blocking member into its respective position for moving the dead bolt into its respective position, is at least partially sequentially realized.

[0016] According to the invention, the change between the blocking position and the release position of the blocking member is produced at least over a portion of the activation movement of the activating element. In this case, the change of the respective position of the dead bolt is performed in operative connection with the blocking member such that a movement of the dead bolt into its respective position, likewise for moving the blocking member into its respective position, is at least partially sequentially realized via the movement of the activating element. In the event the dead bolt is transferred by actuating the activating element for example from the locking position into the opening position, the movement of the activating element effects, at least over a sequential portion of the activation movement, likewise a transfer of the blocking member from the blocking position into the release position. The activating element, which is configured as a catch, is accommodated to be rotatable about a catch axis in the lock housing, wherein the catch may have a toothed structure, by means of which the blocking member can be brought into operative connection such that upon rotation of the catch, a transfer of the blocking member into the release position is enabled. A pressure member may be provided for this purpose, which is accommodated in the lock housing to be mobile about a pressure member axis and disposed such that the toothed structure can be brought against a pressure surface provided at the pressure member, at least over the portion of the activation movement of the activating elements, portion sequentially preceding the activation of the movement of the dead bolt. It is thereby effected that the pressure member performs a movement about the pressure member axis, which may be transferred onto the blocking member via a catch arrangement. On account of the corresponding configuration of the catch arrangement, the blocking member may perform a linear movement within the lock housing, wherein the rotary movement of the pressure member about the pressure member axis corresponds to a pivoting movement.

[0017] In a reverse order, a transfer of the dead bolt from the opening position into the locking position achieves that also the blocking member is again transferred from the release position into the blocking position. Herein, the essence of the invention is that the movement of the blocking member into its respective position is not realized over the entire movement of the activating element for activating the dead bolt, but the change of the position of the blocking member is just realized over a sequential partial portion of the activation movement of the dead bolt.

[0018] Consequently, in the event the dead bolt is transferred from the locking position into the opening position, the activating element can be moved for this purpose. By means of a preceding first portion of the activation movement, the blocking member is transferred from the blocking position into the release position. Following thereafter, the proper activation of the locking mechanism for moving the dead bolt is realized. Consequently, the blocking member is able to still block the locking mechanism by means of an interaction with the gearing element, and the activation movement can be already initiated. Once the transfer of the blocking member from the blocking position into the release position is accomplished, thereupon the activating element can reach engagement with the proper locking mechanism, such that the movement of the dead bolt between the respective positions can be initiated.

[0019] If, however, the dead bolt is to be transferred from the opening position into the locking position, the movement of the blocking member into its respective position is likewise partially sequentially towards the activation movement. In this case, the activation movement can start in the activating element, and the activating element is located already in complete engagement with the locking mechanism, and the dead bolt moves. Once the movement of the activating element is completely performed, the blocking member is transferred from the release position into the blocking position. So that the activating element is able to fully perform the movement, precautions may be taken, such as a defined removal position of a key from a locking cylinder. This position is only reached once the sequence for the movement of the blocking member into the blocking position is realized.

[0020] The sequential movement of the blocking member refers to the movement of the dead bolt, respectively caused by the activating element, meaning that the movement of the blocking member is preceding, following or at least partially preceding or following the movement of the dead bolt. Consequently, the movements may be performed separately from each other or may partially overlap. For example, the activating element may initially reach an operative connection with the blocking member, and thereupon, i. e. sequentially following thereafter, reach operative connection with the proper locking mechanism for moving the dead bolt. Said sequential order of the respective operative connections may happen as well in the reverse order or they may partially overlap each other.

[0021] According to the present invention, at least one of the activating elements may be formed by means of a follower, which is configured for a rotation-transferring reception of a manually manipulatable handle element, in particular of a thumb rotation element and/or of a door knob. So-called thumb rotation elements are known for such locks, which are provided towards the inside of the building or the room, which is supposed to be locked by means of the door including the present lock. The thumb rotation element causes a movement of the dead bolt, which can be simultaneously generated by means of a key in a locking cylinder. Obviously, such a thumb rotation unit is just provided on the inside of the door. However, in the context of the present invention, the follower may serve for the reception of a handle, such as a door opener or a door knob.

[0022] Furthermore, it may be provided that the activating element is configured as a catch for a rotation-transmitting operative connection to a locking cylinder. Both activating elements, a follower and a catch may be act respectively on their own or together on the locking mechanism, wherein the respective operative connection is realized via the gearing element for an interaction with the dead bolt.

[0023] According another advantageous embodiment, the gearing element is accommodated to be rotatable about an axis of rotation, wherein the gearing element is furthermore delimited by means of a border-sided a reveal, wherein a latching step is provided in the reveal. In the event the gearing element is configured in the shape of a disk and accommodated rotatably, almost centrally on an axis of rotation within the lock housing, the reveal is formed by means of the border of the disk-shaped gearing element. In this case, the latching step within the reveal of the gearing element may be formed by means of a radius step, a notch or a recess in the reveal of the gearing element.

[0024] Corresponding to the latching step, the blocking member preferably includes a blocking conformation, which is configured for latching in the latching step of the gearing element, wherein the latching happens once the blocking member is located in the blocking position. As a consequence, on account of the interaction between the activating element and the blocking member, the blocking member with the blocking conformation needs to be removed from the latching step, in order to release the rotary movement of the gearing element. If the blocking member is in the blocking position and engages into the latching step, the rotation of the gearing element about the axis of rotation is impeded, such that the transfer of the dead bolt is at least prevented from its locking position into its opening position.

[0025] It is of particular advantage, if the blocking member is linearly guided in the lock housing between the blocking position and the release position, wherein a spring element may be provided, which is pretensioned by the blocking member in the direction towards the blocking position. In the event at least one of the activating elements is not in engagement with the blocking member, the spring element ensures that the latter always remains in the latching step in the reveal of the gearing element, in order to prevent a transfer of the dead bolt from the locking position into the opening position.

[0026] According to another advantageous embodiment of the inventive lock, the activating element configured as a follower is accommodated in the lock housing to be rotatable about a follower axis, wherein the follower includes a catch crown, which is rotatable by means of the manually manipulatable handle element and is configured for transferring the blocking member into the release position upon a rotating movement for entraining an unblocking catch provided at the blocking member. In this case, the manually operable handle element acts as rotation-transferring onto the follower, which is rotated about the follower axis. The unblocking catch is conformed to the blocking member and cooperates with a corresponding conformation at the catch crown. The radial arrangement of the respective catch at the catch crown for the engagement in the unblocking catch is configured such that the respective at least partial subdivision of the interaction between the follower and the blocking member, as well as of the follower and the locking mechanism is created.

[0027] Furthermore, it may be provided that in addition to a lever element is disposed to be rotatable about the follower axis and can be activated by means of the catch crown after traveling through a sequentially preceding portion of the activation movement of the blocking member by means of the catch crown by means of rotating along about the follower axis, wherein the lever element is operatively connected to the gearing element in order to move the dead bolt. The catch crown may have for example a crown shape configuration with respective cam-shaped conformations. Furthermore, the lever element has cam-shaped conformations, which protrude into gaps between the cams of the catch crown. In the event the catch crown is immediately entrained into rotary movement by rotating the handle element accommodated in the follower, the catch crown may already act upon the blocking member, and transfer the latter for example from the blocking position into the release position. Only by one or more cams abutting between the catch crown and the lever element, sequentially thereafter also the lever element is entrained into a rotary movement about the follower axis. As a consequence, the lever element is able to cooperate with the locking mechanism, wherein the gearing element has already been released by the blocking member. This sequence of movements may be also realized in the corresponding reverse order.

[0028] An advantageous embodiment of the catch arrangement between the pressure part and the blocking member comprises a ratchet disposed at the blocking member, which is positively fitted into a recess fitted into a pressure part for transferring the movement. Obviously, the operative connection between the catch and the blocking member may be also directly realized without the pressure part, in that for example a portion of the catch reaches abutment at a portion of the blocking member.

[0029] The gearing element may include a first toothed crown, which can be brought into meshing engagement with the toothed structure of the catch, for activating the movement of the dead bolt. In this case, the pressure surface in the movement space of the toothed structure of the catch may be disposed in such a way that the movement of the pressure part by abutment of the toothed structure against the pressure surface of the pressure part is realized for transferring the blocking member from the blocking position into the release position prior to the meshing engagement of the toothed structure in the toothed crown. In this case, the toothed structure of the catch presses, via the toothed tips, against the pressure surface of the pressure part. In this case, the pressure part performs a pivoting movement about the pressure part axis and moves the blocking member, via the catch arrangement, simultaneously linearly out of the blocking position into the release position. Therefore, the toothed structure of the catch fulfils two functions, namely on the one hand pushing away the pressure part beyond the tooth tips and on the other hand, realizes a meshing engagement with the toothed crown at the gearing element. As the blocking member is pretensioned by means of the spring element in the direction towards the blocking position, the spring element likewise moves the pressure part into a rotary position, in which the pressure part is at least located in the area of the pressure surface into the movement space of the toothed structure of the catch.

[0030] The gearing element may include a bolt, which is disposed to extend into a guiding coulisse provided in the dead bolt, wherein the dead bolt is accommodated in the lock housing to be pivotable via a dead bolt shaft, such that, upon rotating the gearing element, a pivoting of the dead bolt is enabled between the protruding and the retracted positions. The dead bolt may be retained both in the locking position and in the opening position by means of a spring element. In the event the bolt, which forms the connecting member between the gearing element and the dead bolt, is guided beyond a dead-centre line, respective dead-centre kinematics may come into effect, which is caused by the spring load onto the dead bolt. Thus, the dead bolt snaps into both its locking position and its opening position, once the dead bolt has been pivoted by means of the gearing element in such a way that the dead bolt shaft is sufficiently spaced apart from the dead-centre line.

[0031] The increase of the protective effect of the lock, in addition to the inventive arrangement of the blocking member, may be furthermore achieved in that the opening in the faceplate is shielded for pivoting the dead bolt through a flexibly guided separating plate. Furthermore, it may be intended that the follower may be selectively blocked by means of a blocking body, in that a ratchet provided at the blocking body may latch into a recess, which prevents rotatability of the follower. Furthermore, the locking mechanism may be additionally protected by means of hardened plates, which are affixed laterally at the lock housing. Furthermore, rotary bolts protruding from the lock housing may be hardened. In addition, the dead bolt, which is configured as a pivoting dead bolt, may be protected against mechanical cutting procedures in that at least one intermediate layer of the dead bolt head is hardened.

[0032] The pivoting dead bolt may be likewise protected against cutting through in that hardened cylinder pins rotatable about their axis are mounted in the dead bolt head. The functional space of the latch-bolt mechanism towards the space of the locking mechanism may be preferably protected by means of further hardened separating plates.

[0033] The position of the dead bolt may be in particular detected by an incorporated microswitch for reporting a change in the position of the dead bolt to an external unit. The dead bolt movement may be likewise detected by means of an installed motion sensor of another known constructional type.

[0034] Furthermore, the lock housing may include a faceplate, wherein the blocking member is disposed in the lock housing on the side opposite the faceplate, and wherein the direction of movement of the blocking member between the locking position and the release position may be oriented preferably parallel to the direction of extension of the faceplate. Thereby, the advantage is achieved that a forced release of the blocking member is further complicated or made impossible, because the arrangement of the blocking member opposite the faceplate includes a particularly large distance towards the opening in the faceplate.

[0035] In particular the arrangement of the blocking member is concealed by the locking mechanism within the lock housing, such that a reachability of the blocking member via the opening in the faceplate is prevented.

[0036] For further improving the burglary safety, at least one and preferably two separating plates may be provided, which are disposed in such a way at the gearing element that a transfer of the blocking member from the blocking position into the release position by of a burglary tool is impeded or at least prevented.

[0037] Further measures enhancing the invention will be illustrated in the following in detail in conjunction with the description of one preferred exemplary embodiment of the invention based on the Figures. In the drawings:

Figure 3 shows an exemplary embodiment of the pivoting dead bolt lock according Figure 2 with a blocking member, which is located in a release position,

Figure 4 shows an enlarged view of the arrangement of the locking mechanism as well as of the blocking member and of the operative connection to the activating elements,

Figure 5 shows a perspective view of the arrangement of the locking mechanism as well as of the operative connection of the activating elements towards the blocking member,

Figure 6 shows a perspective arrangement of the blocking member in the area of the follower, and

Figure 7 shows a perspective view of an exemplary embodiment of the blocking member.

[0038] Figure 1 shows a lock 1 forming said species according to the state-of-the-art and has been already described above.

[0039] Figures 2 and 3 show a lock 1, which is configured as pivoting dead bolt lock 1. The lock 1 has a lock housing 2, in which the locking mechanism with a dead bolt 3 is accommodated. The dead bolt 3 is respectively shown in a locking position, in which the latter protrudes from a faceplate 28 on the frontal side of the lock housing 2.

[0040] The dead bolt 3 cooperates with the locking mechanism and forms a component of the locking mechanism, wherein a gearing element 6 is shown as the central structural component, which is accommodated in the lock housing 2 to be rotatable about an axis of rotation 8. The gearing element 6 includes both an operative connection to a follower 4, which forms the first activating element, and to a catch 5, which forms the second activating element 5. The follower 4 is rotatable about a follower axis 12, wherein the catch 5 is accommodated in the lock housing 2 to be rotatable about a catch axis 16.

[0041] The follower 4 cooperates with a lever element 15, which has a toothing with the gearing element 6. Furthermore, the catch 5, via a toothed structure 17, forms a toothing with a toothed crown 24, which is provided at the gearing element 6 in the direction towards the catch 5. It is via the respective toothings between the activating elements 4 and 5 as well as the gearing element 6, that the latter can be entrained into rotation about the axis of rotation 8 for moving the dead bolt 3 between the locking position and the opening position.

[0042] A blocking member 7 is illustrated in Figure 2, which is located in the blocking position I. A blocking conformation 10 is provided at the blocking member 7, which latches into a latching nose 9, which is fitted into a reveal of the gearing element 6. As a consequence, the latching action of the blocking conformation 10 in the latching step 9 prevents a rotation of the gearing element 6 about the axis of rotation 8, such that a pivoting movement of the dead bolt 3 is impeded.

[0043] The blocking member 7 is pretensioned into the blocking position I by means of a spring element 11, wherein the blocking member 7 can be transferred into the release position, in which the member by means of an unblocking catch 14, which is conformed to the blocking member 7, can be transferred into the release position by means of the catch crown 13 of the follower 4 against the pretensioning force of the spring element 11. In the event the catch crown 13 is entrained into a rotary movement about the follower axis 12, for example by means of rotating a thumb rotating unit, one prong at the catch crown 13 is able to entrain the unblocking catch 14 in such a way that the blocking member 7 is moved in the direction towards the spring element 11, which effects a transfer of the blocking member 7 from the blocking position I into the release position II.

[0044] If, however, a transfer of the blocking member 7 is caused by the catch 5, the catch 5 is initially rotated about the catch axis 16, for example by rotating a key in a locking cylinder. In this case, the toothed structure 17 travels in the direction towards a pressure part 18, which has a catch arrangement towards the blocking member 7. In the event the pressure part 18 is pivoted about the pressure part axis 19, in that the toothed structure 17 reaches abutment against the pressure surface 20 of the pressure part 18, the blocking member 7 is likewise moved in the direction towards the spring element 11 by pivoting the pressure part 18. Only subsequently, the toothed structure 17 of the catch 5 can reach engagement with the toothed crown 24 of the gearing element, such that initially, via a first sequence of the rotary movement of the catch 5, an unblocking of the blocking member 7 is realized, and only a following sequence enables the activation of the dead bolt 3 via the locking mechanism.

[0045] A further blocking effect is achieved in that a further blocking body 34 is accommodated in the lock housing 2 to be displaceable or pivotable, which can be latched in a recess 33 provided between the cams 32 of the catch crown 13. In this case, the blocking body 34 may be manually moved, wherein the manipulation of the blocking body 34 by means of a selector element can be realized, which is preferably enabled via a button in the faceplate. In this case, an electromotive movement of the blocking body 34 is likewise possible.

[0046] Figures 4 and 5 show an enlarged view of the locking mechanism, which is in operative connection with the blocking member 7. In this case, the activation of the locking mechanism both by means of the follower 4 and by means of the catch 5 is shown. It can be seen in particular that the pressure part 18, in particular in the area of the pressure surface 20 protrudes into the movement space of the toothed structure 17 of the catch 5, when the catch 5 is rotated about the catch axis 16. In this case, the toothed structure 17, via the tooth tips, presses already against the pressure surface 20 of the pressure part 18 such that, according to the illustration, already a rotary movement about the pressure part axis 19 has been performed. On account of the catch arrangement 21, formed by a ratchet 22, which latches in a recess 23 within the blocking member 7, simultaneously a longitudinal movement of the blocking member 7 is realized. Furthermore, the spring element 11 is shown, which pretensions the blocking member 7 in the direction towards the blocking position. In particular the catch crown 13 is shown enlarged, which is accommodated to be rotatable about the follower axis 12 and is able to reach engagement with the unblocking catch 14 via a crown-shaped prong.

[0047] In the event the gearing element 6 is entrained into a rotary movement about the axis of rotation 8, the bolt 25 likewise travels around the axis of rotation 8. The bolt 25 is guided in a guiding coulisse 26 within the dead bolt 3, such that pivoting the dead bolt 3 about the dead bolt shaft 27 can be achieved. The opening 30 can be seen within the faceplate 28, wherein the dead bolt is respectively shown in the retracted position. With the intention to prevent penetration of a burglary tool into the area of the blocking member 7 within the lock housing 2, separating plates 29a and 29b are provided on the gearing element 6. These cover in particular the area of the pressure part 18 in the direction towards the opening 30 in the faceplate 28, such that the unblocking of the blocking member 7 by means of a burglary tool, which is introduced into the opening 30, is prevented.

[0048] Figure 6 shows an exemplary embodiment of the catch crown 13, which is accommodated to be rotatable about the follower axis 12 of the follower 4, in an enlarged perspective view. In the event the follower 4 and consequently the catch crown 13 are rotated clockwise, the illustrated cam 32 of the catch crown 13 reaches abutment against the unblocking catch 14. As a consequence the blocking member 7 is displaced in the direction of the arrow shown. Thereby, the blocking conformation 10 provided at the blocking member 7 gets out of the latching step (not illustrated), wherein the movement of the blocking member 7 is realized against the force of the spring element 11.

[0049] Figure 7 shows an exemplary embodiment of the blocking member 7, which is manufactured as a stamped bending part from sheet metal in a perspective view. The blocking member 7 comprises a basic portion, wherein the latter in turn is subdivided into a horizontal and a vertical part. Thereby, a secure guidance of the blocking member 7 within the lock housing 2 of the lock 1 can be achieved. On the left side in the illustration, the unblocking catch 14 for unblocking by means of the catch crown 13 is illustrated. The blocking conformation 10 can be seen in the centre, which serves for latching in the latching step 9 within the reveal of the gearing element 6. On the right hand side, the blocking member 7 likewise has a ratchet-like configured conformation 22, which as a ratchet 22 penetrates into the recess 23 in the pressure part for forming the catch arrangement 21 between the pressure part 18 and the blocking member 7.

[0050] The invention in its configuration is not limited to the above presented preferred exemplary embodiment.
