Description

[0001] DUAL CODE LOCK

[0002] The present invention relates to a dual-code lock according to the preamble of claim 1.

[0003] Dual-code locks of this type are used when an object, such as a locker or a piece of furniture, is to be available to two users without them having to find out about a single opening code, also known as a lock secret.

[0004] In a dual-code lock known from DE 10 2019 129 282 B4, one of the locking secrets is freely programmable, while the second locking secret is a non-changeable locking secret of the respective dual-code lock.

[0005] The object of the present invention is to provide a dual-code lock in which two locking secrets can be stored independently of each other.

[0006] The problem is solved by a dual-code lock with the features of claim 1.

[0007] The dual code lock according to the invention comprises a lock housing, an actuating element for adjusting a lock bolt, at least one code wheel rotatably mounted in the lock housing about a pivot axis, and a first adjusting bushing arranged coaxially to the code wheel on a first end face of the code wheel, with a coding notch in a lateral surface of the adjusting bushing.

[0008] The dual code lock according to the invention further comprises a first rocker arm partially encompassing the at least one code wheel, with a pivot axis pivotably attached to the lock housing, a locking axis extending parallel to the pivot axis, and a crossbar resting on the lateral surface of the first adjusting bushing.

[0009] The first rocker switch can be pivoted between a release position, which unlocks the actuator when the first key secret has been entered using at least one code wheel, and a locking position, which locks the actuator. A second actuating bushing, arranged coaxially to the code wheel, is located on a second end face of the code wheel and has a coding notch in a cylindrical surface of the bushing.

[0010] The dual code lock further features a second rocker arm that partially encompasses at least one code wheel, with a pivot axis pivotally attached to the lock housing, a locking axis extending parallel to the pivot axis, and a crossbar resting on the outer surface of the second adjusting bushing.

[0011] The second rocker switch can be pivoted between a release position that enables the actuating element when the second locking secret has been entered using at least one code wheel, and a locking position that locks the actuating element.

[0012] All adjusting bushings are detachably and rotationally fixed mounted on the respective code wheel.

[0013] With a dual-code lock designed according to the invention in this way, it is possible to use two independent locking secrets that are freely programmable.

[0014] Advantageous embodiments of the invention are the subject of the dependent claims.

[0015] According to an advantageous embodiment, the dual-code lock has a first programmer with which the at least one first setting socket for setting the first locking secret can be decoupled from the at least one code wheel, and a second programmer with which the at least one second setting socket for setting the second locking secret can be decoupled from the at least one code wheel, in order to be able to enter a locking secret via the at least one code wheel in the decoupled state and to reconnect the respective setting sockets to the code wheel after entering the locking secret.

[0016] According to a preferred embodiment of the invention, the first and second programmers each have a slider and a number of retaining elements connected to the respective actuating sockets, corresponding to the number of code wheels. In a further advantageous embodiment, the slider of the first programmer is coupled to the pivot axis of the first rocker via a locking element, such that the slider can only be moved into the programming position, in which the at least one first actuating socket is decoupled from the code wheel, when the first rocker is in the release position.

[0017] Accordingly, the slider of the second programmer is also coupled to the pivot axis of the second rocker via a blocking element, such that the slider can only be moved into the programming position, which is decoupled from the code wheel by at least one second actuator socket, when the second rocker is in the release position.

[0018] According to an advantageous further development of the invention, at least one coupling element projecting into a receptacle on the end face of the code wheel facing the respective code wheel is arranged from an end face of the adjusting bushings facing the respective code wheel.

[0019] In an initial design, the coupling element and the receiver are positioned centrally to the axis of rotation of the code wheel and together form a positive fit around the axis of rotation of the code wheel.

[0020] This enables a reliable, rotationally fixed coupling of the adjusting bushings to the code wheels, in order to store a locking secret on the code wheels.

[0021] According to an alternative design, several coupling elements shaped like pins protrude from the end face of the adjusting bushings, which can be inserted into the receptacles on the end face of the code wheel facing the adjusting bushings.

[0022] The formation of several pins and corresponding receptacles in the front face of the code wheels also enables a reliable, rotationally fixed coupling of the adjusting bushings to the code wheels.

[0023] In a further advantageous embodiment, the dual-code lock has a reset element coupled to the actuating element and the at least one code wheel, which, when the actuating element is actuated, rotates the at least one code wheel into a predetermined initial position. With the aid of such a reset element, the key secret is reliably obscured during the opening of the lock, so that it cannot be read by unauthorized persons.

[0024] According to a further advantageous embodiment, the dual-code lock has at least one actuating contour arranged on the actuating element, which is in contact with an extension piece of the first or second programmer, for resetting the first or second locking secrets to an output locking secret corresponding to a predetermined initial position of the at least one code wheel with each actuation of the actuating element.

[0025] With such a so-called "code reset" function, it is possible that after opening the dual code lock, the initial starting position of at least one of the locking secrets is restored, so that another user can use the compartment secured with the dual code lock without further preliminary measures.

[0026] It is also conceivable that both locking secrets could be reset via such a "code reset" function.

[0027] In yet another variant, the first locking secret is not reset via a first programmer directly coupled to the actuating element, but via a second rocker coupled to the actuating element and coupling of the first programmer with the second rocker in the direction of movement of the programmer.

[0028] For this purpose, the dual-code lock has at least one actuating contour arranged on the actuating element, which is in contact with the second rocker, wherein the first programmer is coupled to the second rocker in the displacement direction of the slider, for resetting the first locking secret to an output locking secret corresponding to a predetermined initial position of the at least one code wheel with each actuation of the actuating element.

[0029] According to a further embodiment, the dual-code lock has at least one actuating contour arranged on the actuating element, which is in contact with the second rocker, wherein the first programmer is coupled to the second rocker in the direction of movement of the slider, for resetting the first locking secret only after input of the second locking secret and subsequent actuation of the actuating element to an output locking secret corresponding to a predetermined initial position of the at least one code wheel.

[0030] Particularly preferably, the dual code lock has several code wheels rotatably mounted in the lock housing about a pivot axis and a number of first setting sockets (4) and second setting sockets corresponding to the number of code wheels, in order to increase security.

[0048] In the following figure descriptions, terms such as top, bottom, left, right, front, back, etc., refer exclusively to the exemplary representation and position of the dual-code lock, lock housing, rocker switches, programmer, setting sockets, and the like as chosen in the respective figures. These terms are not to be understood as restrictive; that is, these references may change due to different working positions, mirror-symmetrical design, or similar factors.

[0049] In Figure 1, reference numeral 1 denotes a total embodiment of a dual-code lock according to the invention.

[0050] The dual code lock 1 essentially comprises a housing 15, an actuating element 11 and a lock core 2 shown in Figures 2 and 8 to 12 with at least one code wheel 3, four in the embodiment shown in Figure 1 and two in Figures 2 and 8 to 12, which protrude from a front side of the housing 15 and via which a key secret of the lock can be entered.

[0051] The actuating element 11 can be designed, as shown in Figure 1, as a rotary knob attached laterally next to the code wheels 3 on the housing 15, with which a lock bolt (not shown here) can be moved from a locked to an unlocked position.

[0052] Alternatively, the actuating element 11 can also be designed as a rotary element framing the housing 15.

[0053] It is also conceivable, for example, to design the actuating element 11 as a lever protruding from the housing 15, which, after entry of the locking secret, can be moved from a locked position rusted on the housing 15 to an open position free of rust.

[0054] For the sake of clarity, the invention is described below with reference to the exemplary embodiment of a lock core with two code wheels shown in Figures 2, 4 and 8 to 12. In principle, it is also conceivable to design the lock core 2 with only one such code wheel 3 and a correspondingly reduced number of first and second setting bushings 4, 5, or with more than two code wheels 3 and a correspondingly increased number of first and second setting bushings 4, 5.

[0055] As shown in Figure 2, the lock core 2 has, in addition to the code wheels 3 which are rotatably mounted in the lock housing 15 about a common axis of rotation A, a first adjusting bushing 4 arranged coaxially to the code wheel 3 on a first end face of the code wheel 3 and a second adjusting bushing 5 arranged coaxially to the code wheel 3 on an opposite second end face of the code wheel 3.

[0056] The first and second adjusting bushings 4, 5 have a cylindrical surface with a coding notch 43, 53 each, via which a locking secret is determined and can be queried in the state coupled to the respective code wheel 3.

[0057] To query a first locking secret, the lock core 2 further has a first rocker 6 that partially encompasses the code wheels 3 and to query a second locking secret a second rocker 7 that partially encompasses the code wheels 3.

[0058] The two rockers 6, 7 are preferably mounted on opposite sides of the code wheels 3 in order to be able to perform a pivoting movement independently of each other.

[0059] Both rockers 6, 7 have a pivot axis 62, 72 pivotally attached to the lock housing 15, a locking axis 61, 71 extending parallel to the pivot axis 62, 72 and a crossbar 63, 73 for each of the code wheels 3 resting on the outer surface of the adjusting bushings 4, 5.

[0060] The crossbars 63 of the first rocker 6 rest on the outer surfaces of the first adjusting bushings 4 and the crossbars 73 of the second rocker 7 rest on the outer surfaces of the second adjusting bushings 5.

[0061] The first rocker 6 can be pivoted about the pivot axis 62 between a release position which releases the actuating element 11 when the first locking secret has been entered with the code wheels 3 and a locking position which locks the actuating element 11.

[0062] The release position for the first locking secret is achieved by the crossbars 63 being inserted into the coding notches 43 of the first adjusting bushings 4 via the code wheels 3 after the first locking secret has been entered, thereby pivoting the first rocker 6 from the locking position to the release position.

[0063] The second rocker 7 can also be pivoted about the pivot axis 72 between a release position that releases the actuating element 11 when the second locking secret is entered with the code wheels 3 and a locking position that locks the actuating element 11.

[0064] The release position for the second locking secret is achieved by the crossbars 73, after the second locking secret has been entered, lying in the coding notches 53 of the second adjusting bushings 5 ​​on the other end face of the code wheels 3, thereby pivoting the second rocker 7 from the locking position to the release position.

[0065] To block movement of the actuating element 11, an arm 64, 74 with a locking piece 65, 75 is arranged on the locking axes 61, 71 of the rockers 6, 7, wherein the locking pieces 65, 75 interact independently of each other with a locking counterpart 17 on the actuating element 11 such that in the release position of one of the rockers 6, 7 the actuating element 11 is released for movement.

[0066] In order to enable the programming of two independent locking secrets, all adjusting sockets 4, 5 are detachably and rotationally fixed to the respective code wheel 3 in engagement.

[0067] A first programmer 9 is provided for setting the first locking secret, with which the first adjusting sockets 4 can be decoupled from the code wheels 3.

[0068] Accordingly, a second programmer 10 is provided, with which the second adjusting sockets 5 for setting the second locking secret can be decoupled from the code wheels 3. Both programmers 9, 10 each have a slider 91, 101 and a number of retaining elements 92, 102 corresponding to the number of code wheels 3, which are connected to the respective adjusting sockets 4, 5.

[0069] In the embodiment shown here, the retaining elements 92, 102 are designed as forks which engage in correspondingly undercut drive flanges 43, 53 of the actuating bushings 4, 5 and thereby, when the slider 91 of the first programmer 9 is moved in the decoupling direction, preferably parallel to the pivot axis of the first rocker 6, decouple the first actuating bushings 4 from the code wheels 3 and, when the slider 101 of the second programmer 10 is moved in the decoupling direction, preferably parallel to the pivot axis of the second rocker 7, decouple the second actuating bushings 5 ​​from the code wheels 3.

[0070] As further shown in detail in Figure 7 and also in Figures 2, 4 and 8 to 10, the slider 91 of the first programmer 9 is preferably coupled to the pivot axis 62 of the first rocker 6 via a blocking element 93.

[0071] In the illustrated embodiment, the coupling is such that the slider 91 can only be moved into the programming position in the release position of the first rocker 6, in which the first actuating bushings 4 are decoupled from the code wheels 3.

[0072] In a corresponding manner, the slider 101 of the second programmer 10 is coupled to the pivot axis 72 of the second rocker 7 via a blocking element 103, i.e., the slider 101 can only be moved into the programming position, which is decoupled from the code wheels 3, in the release position of the second rocker 7.

[0073] For the rotationally fixed coupling of the adjusting bushings 4, 5 to the code wheels 3, at least one coupling element 42, 52 is arranged on an end face of the adjusting bushings 4, 5 facing the respective code wheel 3, projecting into a receptacle 31 on the end face of the respective code wheel 3 facing the adjusting bushing 4, 5.

[0074] In the embodiment shown in Figures 2 and 6, several coupling elements 42, 52, designed as pins, project from the end faces of the adjusting bushings 4, 5 and can be inserted into the receptacles 31 on the end face of the code wheel 3 facing the respective adjusting bushing 4, 5. It is also conceivable to provide the pins on the code wheels and the receptacles 31 on the end faces of the adjusting bushings 4, 5.

[0075] Furthermore, it is also conceivable to position only a coupling element 42, 52 and a receptacle 31 centrally to the axis of rotation A of the code wheel 3, which together form a positive locking connection around the axis of rotation A of the code wheel 3, for example in the form of pins designed as polygons that project into a corresponding polygon receptacle in the end face of the code wheel 3.

[0076] As further shown, for example, in Figures 2, 3, 11 and 12, the dual-code lock 1 preferably has a reset element 8 coupled to the actuating element 11 and the code wheels 3, by which the code wheels 3 are rotated into a predetermined initial position when the actuating element 11 is actuated. The reset element 8 is preferably controlled by a control cam 18 in the inner surface of the actuating element 11, into which one end of the reset element 8 projects.

[0077] In the embodiment shown in Figure 13, the first locking secret is reset to an initial locking secret with each actuation of the actuating element 11.

[0078] The initial lock secret here refers to a lock secret that corresponds to the predetermined starting position of the code wheels 3, for example “0000” when there are a total of four code wheels.

[0079] For this purpose, an actuating contour 19, as shown by way of example in Figure 13, is provided on the actuating element 11, which is in contact with an extension piece 96 of the first programmer 9.

[0080] The extension piece 96 can be coupled to the slide 91 of the programmer 9 or formed as a single piece with the slide 91.

[0081] Once a user has entered the first locking secret via the code wheels 3, the actuation of the actuating element 11 is enabled, as described above.

[0082] By actuating the actuating element 11, in the illustrated embodiment by rotating the actuating element 11 about the axis of rotation A, the actuating contour 19 pushes the first programmer 9 into its programming position, in which the first actuating bushings 4 are decoupled from the code wheels 3.

[0083] Subsequently, as described above, the code wheels 3 are turned back to their predetermined starting position via the reset element 8, for example “00” in the case of a total of two code wheels 3 shown here.

[0084] After the code wheels 3 have been reset, the actuating element 11 is turned back, pushing the slide 91 of the first programmer 9 back into the positioning contour 19 and re-engaging the first positioning bushings 4 with the code wheels 3.

[0085] This resets the first locking secret to an output code corresponding to one of the predetermined starting positions of the code wheels 3.

[0086] It is also conceivable to automatically reset the second locking secret to the initial locking secret with each actuation of the actuating element 11, instead of the first locking secret.

[0087] In this case, an extension piece is provided on the second programmer 10, which interacts with a corresponding contour on the actuating element 11 in the manner described above.

[0088] It is also conceivable, if appropriate extension pieces are provided for both programmers 9, 10, that both locking secrets can be automatically reset to the initial locking secret when the actuating element 13 is activated.

[0089] In another embodiment, shown by way of example and schematically in Figure 14, instead of the extension piece 96 of the slide 91 of the first programmer 9 being coupled to the second rocker 7 in the translation direction of the slide 91 when the actuating element 13 is actuated, the slide 91 of the first programmer 9 is coupled to the second rocker 7 by way of the extension piece 96 of the slide 91 of the first programmer 9.

[0090] The second rocker 7 is operatively connected to an actuating contour 19 on the actuating element 13 and is thus moved together with the first programmer 9 when the actuating element 13 is actuated. This moves the first programmer 9 into its programming position and, as described above, resets the first locking secret to the initial locking secret and returns the code wheels 3 to their initial position.

[0091] The further embodiment variant, shown by way of example and schematically in Figure 15, is based on the embodiment variant according to Figure 14.

[0092] Here, both rockers 6 and 7 are operatively connected to their respective actuating contours 19 and 20 on the actuating element 13. In addition, the slider 101 of the second programmer 10 is coupled to the first rocker 6 in the translational direction of the slider 101.

[0093] This moves the first and second programmers into their programming position, resets both locking secrets to the initial locking secret, and turns the code wheels 3 back to their initial position.

[0094] The further embodiment variant, shown by way of example and schematically in Figure 16, serves to reset the first locking secret to the initial locking secret after the second locking secret has been entered by actuating the actuating element 13.

[0095] For this purpose, the slider 91 of the first programmer 9 is coupled in the translation direction of the slider 91 to the second rocker 7.

[0096] The second rocker 7 only comes into contact with the actuating contour 19 on the actuating element 13 after its pivoting movement and is moved together with the first programmer 9 when the actuating element 13 is actuated.

[0097] This moves the first programmer 9 back into its programming position and, as described above, resets the first locking secret to the initial locking secret.

[0098] In this version, when the first locking code is entered, only the code wheels 3 are turned back to their initial position when the actuating element 13 is pressed. Reference numeral list
