Description

Description [0001] The present invention relates to a lock for a door or the like, which is configured in particular as a slidable dead bolt lock with a lock housing, in which at least one locking mechanism with a dead bolt is located. Locks of the present type are mostly utilized in doors, gates or for example windows.

[0002] In this case, the dead bolt is movable into a locking position, in which the latter protrudes from the lock housing for locking the door, and in this case, engages for example into a stationary strike plate, the so-called counter-locking part, and wherein the dead bolt can be moved into an opening position, in which the dead bolt can be moved back into the lock housing for opening the door.

[0003] Furthermore, the locking mechanism comprises at least one transmitting element, which is rotatably accommodated within the lock housing and is configured for the interaction with a gearing element, wherein, on account of the interaction, the dead bolt can be moved between the locking position and the opening position.

[0004] A lock of this species having an improved locking mechanism is already known from the document DE 10 2008 009 511.7-15. In this case, the gearing element is accommodated in the lock housing to be linearly movable for the interaction between the dead bolt and the transmitting element and is configured in the shape of a toothed rack with a backsided geometrical shape of the driver. In this case, the dead bolt travels linearly between the opening position and the locking position and consequently protrudes through an opening from the faceplate of the lock housing. The opening required for passing the dead bolt through the faceplate of the lock housing results in the disadvantage of insufficient resistance against manual burglary attempts.

[0005] Another lock is likewise known from the document EP 1 589 169 A2 comprising a dead bolt, which can be brought into both a locking position and an opening position. Furthermore, a transmitting element is shown, which can be brought rotatably into an interaction with a gearing element. Furthermore, the document EP 1 589 169 A2 includes a blocking member for blocking the gearing element.

[0006] The reason for the insufficient resistance in such locks is found in a missing tumbler. Basically, said element or said elements is/are referred to as a tumbler, which positively prevent/s a movement of a dead bolt in an opening position and/or in a locking position. With the locks of the present species, a guard locking of the dead bolt is achieved in that the actuation of the dead bolt mechanism is non-positively maintained in the respective locking position and/or opening position. Another arrangement of a guard locking and increasing the resistance for forming a securing blockage of the movement of the dead bolt is not intended in such locks.

[0007] Therefore, it is the object of the present invention to provide a lock of the present species with an improved safety effect.

[0008] 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.

[0009] The invention includes the technical teaching that at least one blocking member for the securing blocking of the movement of the gearing element is provided and disposed in such a manner that the interaction between the transmitting element and the gearing element allows for at least an unblocking of the blocking member, in order to provide for a release of the movement the gearing element, by means of which the dead bolt is transferable from the locking position into the opening position.

[0010] In this case, the invention is based on the idea to provide a blocking member acting like a tumbler, which can have such an effect on the movement of the gearing element that a positive guard locking is enabled. In this case, the essence of the invention resides in the unblocking of the blocking member exclusively via the interaction between the transmitting element and the gearing element.

[0011] In the event the dead bolt would be forcibly transferred from its locking position into its opening position, no interaction is realized between the transmitting element and the gearing element, because just a flow of forces from the dead bolt onto the gearing element is present. However, the unblocking action of the blocking member requires the interaction of the transmitting element towards the gearing element such that the blocking member, even under aggressive application of forces onto the dead bolt in the direction towards the opening position, will remain in the blocking position. As a result, a lock is provided, which is particularly embodied as a slidable dead bolt lock, which has an increased resistance, because the guard locking of the dead bolt is not only realized by means of a single non-positive tumbler.

[0012] It is of particular advantage that the blocking member is accommodated within the gearing element and is movable between a blocking position and a release position. The movement of the gearing element correspondingly moves the blocking member along, wherein the blocking member can be moved in relation to the gearing element both in the blocking position and in the release position. As both the transmitting element and the gearing element perform a movement and the arrangement of the blocking member has an influence on the interaction between the transmitting element and the gearing element, the reception of the blocking member in the gearing element forms a particularly advantageous embodiment.

[0013] According to the invention, the transmitting element includes a driver, which during a rotation of the transmitting element engages in an interaction with the gearing element in such a manner that the blocking member can be transferred from the blocking position into the release position. The transmitting element is configured in a disc-shape and forms a rotatable component of the locking mechanism. On a planar surface of the transmitting element, the driver is conformed in a tenon-shape, such that, during a rotation of the transmitting element, a movement of the driver is generated along a circular path. As a consequence, during a rotation of the transmitting element, the driver moves towards the still resting gearing element. In this case, a movement of the driver in the direction towards the gearing element along the circular path is performed such that a movement component is directed perpendicularly towards the gearing element and another movement component is directed perpendicularly towards the first movement component, in which simultaneously the gearing element is moved for moving the dead bolt.

[0014] At least one part of the locking mechanism includes a reception unit, in which at least the transmitting element and the gearing element are accommodated. As the blocking member is accommodated in the gearing element, the latter is likewise incorporated into the reception unit. In this case, the transmitting element is rotatably accommodated in a rotary reception of the reception unit and the gearing element is accommodated to be linearly movable in a linear reception of the reception unit, wherein the mobility of the gearing element is in particular given in relation to the dead bolt.

[0015] The linear reception is fitted into the reception unit and includes a guiding groove within the body of the reception unit. The linear reception configured as a guiding groove has at least one groove walling, wherein the geometrical blocking shape is configured as a latching groove in an edge of the groove walling and includes a free-spin over a length, which is determined in such a way that the blocking member can be displaced at least over a portion of the path of the gearing element in the latching groove. In the event the driver travels along the circular path towards the gearing element, the movement component of the driver pushes the blocking member in the direction of the gearing element and from the blocking position into the release position. The movement component of the driver in the direction of movement of the gearing element achieves a simultaneous start of the movement of the gearing element with the movement of the blocking member from the blocking position into the release position. As a consequence, the blocking member travels over a free-spin length within the latching groove, and will, however, before the end of the latching groove, occupy the release position or at least a release area such that the gearing element can be moved beyond the latching position.

[0016] According to another advantageous embodiment, the gearing element includes a pocket-like blocking member reception for accommodating the blocking member, wherein the interaction of the transmitting element with the gearing element comprises an engagement of the driver in the blocking member reception. Upon a movement of the driver on account of the rotary motion of the transmitting element for entraining the gearing element, the driver plunges into the blocking member reception in such a way that, when the driver plunges into the blocking member reception, the driver can transfer the blocking member from the blocking position into the release position. As a consequence, the blocking member is linearly guided in the blocking member reception, wherein the guiding direction is directed perpendicularly to the direction of movement of the gearing element.

[0017] Furthermore, it is of advantage that a spring element is provided, which biases the blocking member into the blocking position such that the driver realizes the transfer of the blocking member from the blocking position into the release position against the spring force of the spring element. In the event the driver does not engage in the blocking member reception, the blocking member is always biased in the direction towards latching in the latching groove. As soon as the gearing element reaches a linear position, in which the blocking member covers the blocking groove, on account of the spring tension, the blocking member leaps into the blocking position.

[0018] So that the blocking member engages in the latching groove, the blocking member includes a blocking protrusion, wherein the reception unit comprises a planar surface, on which the blocking member can slide with at least one lateral body surface. As a consequence, the blocking member may be guided between the planar surface of the reception unit and the gearing element, wherein the blocking member may be likewise guided without abutment at the planar surface, for example via a guiding groove within the gearing element.

[0019] According to the invention, the operative connection between the dead bolt and the gearing element includes a lever element, wherein the transfer of the linear movement of the gearing element onto the lever element is realized with a toothing, and wherein the lock is in particular embodied as a slidable dead bolt lock and the movement of the dead bolt is linearly realized. The transmitting element may include a centrically disposed geometrical transmission shape, in which the driver part of a locking cylinder can latch. As a consequence, the rotation of the locking cylinder provokes the rotation of the transmitting element.

[0020] With the intention to reverse the dependence of the direction of rotation of the locking cylinder from the direction of movement of the dead bolt between the opening position and the locking position, in a further development, a pinion may be disposed between the transmitting element and the lever element. Obviously, the locking mechanism is not limited to the mentioned components such that the locking mechanism may comprise all the transmitting elements for the movement of the dead bolt known from the state-of-the-art. In particular, a connection to a handle may be provided, which is accommodated by means of a follower, such that upon a rotation of the follower by means of the handle, a lever element can be pivoted, with which the dead bolt can be likewise moved between the opening position and the locking position. Such a handle is also referred to as a thumb rotation unit and serves for moving a dead bolt from the door inside of a building or a room as an alternative to an actuation of the lock by means of a locking cylinder with a key.

[0021] Furthermore, in addition to an embodiment of the lock as a slidable dead bolt lock, the latter may be embodied as a pivotable dead bolt lock, which likewise includes a part of a locking mechanism, which, in the present configuration of the reception unit, is configured with the accommodated transmitting element and the gearing element.

[0022] Furthermore, according to the invention, for forming the toothing, at the gearing element is disposed a toothed rack portion and at a lever element is disposed a toothed segment, wherein the linear reception in the reception unit preferably extends at an angle of inclination comprised between 10 0 and 80 ° in relation to the direction of movement of the dead bolt, with the intention of guiding the gearing element in an oblique manner. In addition to an advantageous economy of space for reducing the construction dimensions of such a slidable dead bolt lock, also an arrangement of the linear reception at an angle of inclination comprised between 10 0 and 80 ° in relation to the direction of movement of the dead bolt is advantageous, because with a gearing element moved in an oblique manner, a burglary tool acting from the outside will have more difficulties accessing the element. In the event the gearing element would be moved parallel to the dead bolt, a manipulation of the position of the blocking member and in particular a transfer of the blocking member into the release position would be simplified. Flowever, a manipulation of the blocking member in its position is next to impossible, as long as the gearing element extends at a slant within the linear reception, and consequently a direct access to the linear reception from the opening of the faceplate is prevented.

[0023] According to another advantageous embodiment, a driver bolt is disposed at the lever element, wherein the dead bolt may comprise a guiding coulisse, in which the driver bolt is guided. The guidance of the driver bolt within the guiding coulisse may be realized in that, during a pivoting movement of the lever element about a pivoting axis, a movement of the dead bolt from the locking position into the opening position is enabled.

[0024] Furthermore, the reception unit may be configured in two-parts, wherein the arrangement formed from the transmitting element and/or the gearing element may be accommodated sandwiched between a first part and a second part of the reception unit, which second part is configured to be complementary to the first one. The transmitting element may be provided twice within the reception unit, wherein each one of the two transmitting elements has its own driver, which are positioned angularly offset between the two transmitting elements. As a consequence, during a rotation of the locking cylinder and a co-rotation of the transmitting element, the position of the engaging first driver may differ from the rotary position of the locking cylinder during an engagement of the second driver in the gearing element. This circumstance results in the advantage that, when a key is in the withdrawal position from the locking cylinder, none of the two drivers can cooperate with the gearing element. As a consequence, even introduction of forces into the dead bolt and a linear movement of the gearing unit, which can be generated thereby, will not produce an interaction with the transmitting element.

[0025] Another improvement of the interaction between the driver and the blocking member results from a geometrical driver shape within the blocking member, which is disposed in the direction towards the driver of the transmitting element. The driver may engage in the geometrical driver shape in such a way that the movement of the gearing element is realized via the introduction of forces from the driver onto the geometrical driver shape and the transfer of forces onto the blocking member reception. As a result, the driver will just establish contact with the geometrical driver shape within the blocking member, wherein the geometrical driver shape may be adapted to the geometrical shape of the driver.

[0026] 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 a perspective view of the blocking member with a blocking protrusion as well as a geometrical driver shape,

Figure 4 shows a further perspective view of a reception unit as well as of a blocking member, which is shown as latched in a latching groove via a blocking protrusion, and

Figure 5 shows a perspective view of a lock with a first part of a reception unit as well as with a second part of a reception unit in a disassembled condition.

[0027] The lock 1 shown in Figure 1 forms an exemplary embodiment of a lock 1 according to the present invention and is configured as a slidable dead bolt lock. The lock 1 has a lock housing 2, wherein a topsided cover has been removed for the purpose of illustrating the locking mechanism. Said mechanism comprises a dead bolt 3, which is shown in a position protruding from the lock housing 2, whereby the latching position of the dead bolt 3 is represented.

[0028] The locking mechanism has several components accommodated within the lock housing 2, wherein some of the components are separately accommodated in a reception unit 8' for forming a compact partial unit of the locking mechanism, which can be individually manipulated. The reception unit is formed by means of two parts, wherein the reception unit is shown in a disassembled condition such that just a second lower part 8' can be seen.

[0029] A transmitting element 4, 4', which is likewise configured in several parts, is shown within the reception unit 8', wherein in the present view both parts are shown. The transmitting element 4, 4' has a centrically provided geometrical transmission shape 20, which forms a cross and serves for the reception of a driver part of a locking cylinder, which is able to latch in the geometrical transmission shape 20. In the event the locking cylinder is entrained into a rotary motion by means of an introduced key, said rotary motion is transferred by means of the driver part of the locking cylinder via the geometrical transmission shape onto the transmitting element 4, 4', such that a rotary motion is likewise performed within the reception unit 8'.

[0030] According to the embodiment of the lock 1, an interaction between the transmitting element 4, 4' and a gearing element 5 is realized, which is accommodated to be linearly guided within the reception unit 8'. The direction of movement of the gearing element 5 is in relation to the direction of movement of the dead bolt 3 under an angle of inclination, whereby the advantage is achieved that the accessibility of the interaction area between the transmitting element 4, 4' and the gearing element 5 through the opening 21, through which the dead bolt 3 passes through the lock housing 2, is made more difficult.

[0031] A blocking member 6 is disposed in the interaction area between the transmitting element 4, 4' and the gearing element 5. The blocking member 6 serves for the securing blocking of the movement of the gearing element 5, wherein the arrangement of the blocking member 6 is provided according to the invention in such a manner that the interaction between the transmitting element 4, 4' and the gearing element 5 allows for at least one unblocking of the blocking member 6, in order to provide for a release of the movement of the gearing element 5, by means of which the dead bolt 3 is transferable from the locking position into the opening position. A detailed illustration of the interaction between the transmitting element 4, 4' and the gearing element 5 is illustrated in more detail in the Figures 2a, 2b and 2c.

[0032] Figure 2a shows a first part of the reception unit 8, in which a part of the transmitting element 4 is illustrated, wherein furthermore the gearing element 5 is shown, which is guided in a linear reception 5a in the shape of a guiding groove 5a within the reception unit 8. The interaction between the transmitting element 4 and the gearing element 5 is realized via a driver 7, which is not in a direct interaction with the gearing element.

[0033] A blocking member 6 is movably accommodated within the gearing element 5, wherein the guidance of movement of the blocking member 6 within the gearing element 5 is allowed by means of a blocking member reception 10. The direction of movement of the blocking member 6 is perpendicularly to the direction of movement of the gearing element 5, which is dictated by the guiding groove 5a. In the event the transmitting element 4 is entrained into anti-clockwise rotation, the driver 7 travels along a circular path. In this case, the driver 7 plunges into the blocking member reception 10 of the gearing element 5 and reaches contact with the blocking member 6. In the position shown, the blocking member 6 is in a blocking position, wherein, when pushing the driver 7 in the direction of the guide of the blocking member reception 10 for guiding the blocking member 6, a release of the blocking member 6 is performed. Blocking the blocking member 6 for preventing the movement of the gearing element 5 within the guiding groove 5a, will be described in the following in detail based in Figure 2b.

[0034] Figure 2b shows another perspective view of the first part of the reception unit 8, in which the transmitting element 4 is rotatably accommodated. Furthermore, the blocking member 6 is shown, wherein, thanks to the non-illustrated gearing element 5, the blocking action of the blocking member 6 on account of the interaction with a geometrical blocking shape 9 within the reception unit 8 can be clearly revealed. The latching groove 9 forms a geometrical blocking shape, into which a partial portion of the blocking member 6 reaches. The latching groove 9 has a finite length, which in the following will be referred to as a free-wheel length. By means of rotating the transmitting element 4, the driver 7 is entrained into movement and pushes the blocking member 6 in a direction perpendicularly to the extension of the latching groove 9. Thereby, the blocking member 6 leaves the latching groove 9 and can be displaced along the entire length of the guiding groove 5a. If, however, the blocking member 6 is latched in the latching groove 9 - as shown -, the movement of the gearing element 5 is likewise limited to the free-wheel length of the latching groove 9. As a result, on account of the limited movement of the gearing element 5, the dead bolt 3 cannot be transferred from the locking position into the opening position.

[0035] Figure 2c shows the release position II of the blocking member 6 such that the gearing element 5 can be completely displaced within the guiding groove 5a of the reception unit 8. In this case, the driver 7, which is disposed on the transmitting element 4, pushes the blocking member 6 downwards in the blocking member reception 10, while the gearing element 5 is displaced. A further anti-clockwise guidance of the rotary motion of the transmitting element 4 will result in the driver 7 travelling partially back into the blocking member reception 10, wherein however the blocking member 6 remains in the release position II. In the event the transmitting element 4 is rotated back clockwise, the above-described action of transferring the blocking member 6 from the blocking position I into the release position II will be performed in the reverse order. As a consequence, the driver will lift the blocking member out of the latching groove 9.

[0036] Figure 3 shows a perspective view of the blocking member 6. The latter has a geometrical driver shape 19, in which the driver 7 can engage. In the event the blocking member 6 is guided within the blocking member reception 10, the driver 7 just reaches contact with the geometrical driver shape 19. As a consequence, a transmission of forces between the driver 7 and the gearing element 5 only happens via the blocking member 6 itself. Furthermore, the blocking member 6 has a blocking protrusion 12 for latching in the latching groove 9.

[0037] Figure 4 shows another perspective view of the first part of the reception unit 8, in which the transmitting element 4 is accommodated, wherein furthermore the blocking member 6 is shown, and wherein the blocking protrusion 12 of the blocking member 6 is illustrated as latched in the latching groove 9. For the purpose of keeping the blocking member 6 in the blocking position, a spring element 11 is intended, which spring-biases the blocking member 6. In the event a rotary motion of the transmitting element 4 is performed within the rotary reception 4 according to the illustrated rotary arrow, the driver 7 pushes the blocking member 6 against the pre-tension of the spring element 11 into the blocking member reception 10 of the gearing element 5. In this case, the blocking protrusion 12 is lifted out of the latching groove 9, while the blocking member 6 simultaneously performs a longitudinal movement along the guiding groove 5a. The latching groove 9 is fitted into the groove walling 5b of the guiding groove 5, and forms a stair-like step towards the planar surface 8a, on which the blocking member 6 can slide with a lateral body surface.

[0038] Figure 5 shows a view of a lock 1 with a locking mechanism, wherein both a first part 8 and a second part 8' of the reception unit are shown in a disassembled condition. According to the illustration, the transmitting element 4' is accommodated in the second part of the reception unit 8'. Furthermore, the gearing element 5 with the blocking member 6 accommodated therein is located on the second part 8' of the reception unit. The first part 8 of the reception unit has a planar surface 8a, the guiding groove 5a and the latching groove 9 fitted between the planar surface 8a and the guiding groove 5a.

[0039] Furthermore, the rotary reception 4a for the reception of the transmitting element 4’ is shown. In the event the transmitting element 4' is entrained into a rotary motion, the gearing element 5 performs a longitudinal movement under an angle of inclination. The gearing element 5 has a toothed rack portion 14, which is in meshing engagement with a toothed segment 15, wherein the toothed segment 15 is affixed to a lever element 13. On account of the engagement of the toothed rack portion 14 in the toothed segment 15, the lever element 13 is pivoted about a pivoting axis, wherein a driver bolt 16 is mounted to an end side of a lever arm. On account of the pivoting movement of the lever element 13, the driver bolt performs a rotary motion about the pivoting axis 18. The driver bolt 16 is guided in a guiding coulisse 17, which is fitted into the dead bolt 3. On account of the pivoting movement of the driver bolt 16, the dead bolt 3 is linearly moved between the opening position and the locking position. As a consequence, a simple rotary motion of the transmitting element 4' causes a linear movement of the dead bolt 3, which movement can be blocked by means of the blocking member 6.

[0040] The invention in its configuration is not limited to the above presented preferred exemplary embodiment. On the contrary, a number of variants are conceivable, which make use of the illustrated solution, even with basically different types of embodiments. All features and/or advantages including the constructional details, spatial dispositions and process steps, which result from the claims, the description or the drawings, may be essential to the invention, both by themselves and in their most various combinations.
