Description

TECHNICAL FIELD

[0001] The invention relates to a handling device for a lock, having axially successive adjustment bushes which each interact with a number wheel, the adjustment bushes being coupled to one another in a locking position in which handling of the handling element is locked, wherein the adjustment bushes can be brought into a release position with a twist of the number wheel into an opening combination in which the handling element is handleable, wherein the number wheel is uncoupled from the adjustment bushes in a programming position to reset the opening combination. BACKGROUND

[0002] A device of the type described above is described in patent document DE 102014109224 A1. The handling device is part of a combination lock, wherein the number wheels are uncoupled from the adjustment bushes assigned to them in the starting position. The adjustment bushes occupy the release position, so that the locking mechanism interacting with the adjustment bushes can also occupy the release position. The number wheels can be adjusted with respect to the adjustment bushes individually assigned to them, respectively, to set an opening code. Upon a rotation of the handling element, the adjustment bushes are coupled to the number wheels. In conjunction therewith, the number wheels are brought into the zero position, so that the opening code is obscured. To open the lock, the number wheels and the adjustment bushes coupled to the number wheels have to be twisted. By setting the opening code using the number wheels, the adjustment bushes are adjusted to their release position, so that the locking mechanism releases the latch and the rotary knob can be rotated into the open position.

[0003] From patent documents DE 102009016854 A1, EP 2419586 B1 and EP 2942457 B1 combination locks are also known. SUMMARY

[0004] It is an object of the invention to advantageously improve the combination lock described above.

[0005] The task is solved by a programming element. The programming element can be moved from a programming position into a handling position. In the programming position, the number wheels are uncoupled from the adjustment bushes individually assigned to them, respectively. The adjustment bushes occupy their release position. Each adjustment bush can have an action area, which can be formed by a recess, in particular. The action area of the locking mechanism can enter into the recess. The action area can be a protrusion which enters into the recess. The locking mechanism can be spring-loaded, so that the protrusion engaged in the recess holds the adjustment bushes in the release position.

[0006] The programming element can have a blocking element which blocks the manipulability of the manipulation element in the programming position. In the programming position, the number wheel can be rotated independently of the adjustment bushing, so that the opening code can be set by a twist of the number wheel. The programming element can be moved from the programming position into the manipulation position. To this end, the programming element can have a switch knob with which the programming element can be moved relative to the housing of the manipulation device. With the movement of the programming element into the manipulation position, the adjustment bushing is rotationally fixedly coupled to the number wheel assigned to it. With the movement of the programming element into the manipulation position, the blocking element also leaves the blocking position, so that the manipulation element can be moved from the opening position into the locking position. By means of the programming element, it is only possible to manipulate the manipulation element when a new opening code is intentionally stored by coupling the adjustment bushing to the number wheel. This makes it more difficult to store an undesired opening code by unintentionally manipulating the manipulation element after the number wheel has been adjusted from the zero position.

[0007] The programming element can be a slider. The switch knob can be a protrusion which protrudes from the housing. The slider can have two frame legs which extend parallel to one another, which are connected to one another by a cross leg which also extends parallel to one another. The adjustment wheel together with the number wheel assigned to it can be arranged in this frame formed by the frame legs and the cross leg. The programming element is preferably displaced in a direction parallel to an axis about which the adjustment bushing or the number wheel can be rotated. According to a preferred embodiment, a spring element is provided with which the programming element is held in the programming position. The spring element preferably loads the blocking element, which can be the protrusion, into its blocking position. The protrusion forming the blocking element can be located in a recess in a control body in the programming position. The control body can be a cylindrical sleeve which is torsionally assigned to the manipulation element. The manipulation element is preferably a rotary knob which can be rotated about a rotary axis. The control body can be assigned to the rotary knob, which can be displaced in the direction of the rotary axis. A spring element can be provided with which the control body is loaded. If the protrusion of the programming element is engaged in the recess of the control sleeve, the rotary knob cannot be rotated. If the programming element is moved into the manipulation position, the protrusion can be moved out of the recess. The rotary knob is now displaceable.

[0008] The control sleeve can have a cylindrical peripheral surface which adjoins the recess in the peripheral direction about the rotary axis of the rotary knob. After the rotary knob is slightly turned out of the opening position, the protrusion can rest on this cylindrical peripheral surface. This prevents the programming element from being moved back from the manipulation position into the programming position. When the rotary knob is rotated from the opening position into the locking position, the protrusion is guided over this cylindrical peripheral surface.

[0009] With the rotation of the knob from the open position into the locked position, the knob controls the zeroer. The zeroer has a plurality of reset arms which can act on a heart-shaped control curve of the number wheel in order to bring the number wheel into a starting position, for example into a position in which the number zero is displayed respectively. With this adjustment of the number wheel, the adjustment bushing is also adjusted, since it is rotatably coupled to the number wheel. The opening code is thus obscured. With the rotation of the adjustment bushing, the protrusion of the locking mechanism is also moved out of the recess of the adjustment bushing. In order to reduce the force, it is provided that the locking mechanism, which is preferably formed by a rocker, is moved directly before the zero position from the release position into the locked position. For this purpose a push rod is used which acts on an arm of the rocker and is moved by a control curve of the knob. The push rod can be moved parallel to the rotation axis of the knob and has a first end which acts on the arm of the rocker and a second end which is supported on the control curve of the knob when the push rod is moved. The knob thus has a control ramp which can be loaded on the push rod in an axial direction with respect to the rotation axis of the knob in order to pivot the locking mechanism. The control ramp can be formed by a control protrusion. On the control ramp a control flank can be connected along which the second end of the push rod can slide when the zeroer brings the number wheel into the zero position.

[0010] The zeroer can have a handling pin which can be slid on a control curve of the knob. The control curve is designed in such a way that the zeroer is handled both when the knob is rotated from the open position into the locked position and when the knob is rotated from the locked position into the open position.

[0011] The locking mechanism can have a recess into which a latch arranged in the knob engages. The latch can be deflected in a radially inward direction with respect to the rotation axis of the knob against the restoring force of a spring. Thus, the locking mechanism can enter the recess even when it is in the locked position. For this purpose, a head of the latch can slide along a flank of the locking mechanism and be deflected into a cavity of the knob.

[0012] An additional lock can be provided by means of which the latch can be actively pulled out of the recess of the locking mechanism so that the knob can be turned even in the case of an incorrectly set opening code. The additional lock has a lock cylinder which is arranged in the knob.

[0013] If the knob is rotated from the locked position into the open position with the correct setting of the opening code or with the latch retracted, a control cam assigned to the control sleeve comes into play. This control cam has a control curve which extends obliquely to the plane of rotation of the knob and which cooperates with a projection of the programming slide so that the control sleeve is moved in axial direction against the restoring force of a spring which is loaded against it. The projection of the programming slide can have one or more ramps which can be slid along the control curve to move the control sleeve. The projection of the programming slide or the ramp formed by it and the control curve are designed so that directly after the knob begins to be turned out of the locked position, the control sleeve is raised until the projection of the programming slide reaches under the lower edge of the control sleeve. This causes the programming slide to be moved out of the handling position into the programming position. In conjunction with this, the adjustment bushing is moved out of its coupled position with the respective number wheel, which causes the adjustment bushing to be rotatable independently of the number wheel. In the locked position, the projection of the programming element can be placed into a recess in the outer wall of the control body. When entering this recess, the programming element can be moved slightly in the direction of the programming position, but here without losing the coupled position between the adjustment bushing and the number wheel. The edge of this recess forms the control curve along which the control sleeve is moved in axial direction.

[0014] Both the number wheel and the adjustment bushing have a heart-shaped control curve, respectively, which can cooperate with a reset arm of the zero setter. While the heart-shaped curve of the number wheel can be loaded by the reset arm in the programming position and in the handling position, the heart-shaped curve of the adjustment bushing can only be loaded by the reset arm in the decoupled position, which is axially displaced relative to the coupled position. As a result, when the knob is turned from the locked position into the open position, not only the number wheel but also the adjustment bushing enter the starting position. The number wheel is moved into the zero position and the adjustment bushing is moved into the release position.

[0015] The adjustment bushings are arranged axially movably on a shaft. Both ends of the shaft are supported in the housing. The adjustment bushings have a middle section which forms a heart-shaped curve and which has a protrusion axially adjacent thereto. Assigned to the adjustment bushings is a number wheel which is located on a sleeve-shaped extension, which has a coupling pin which extends in axial direction and which can enter a coupling opening in the adjustment bushing. The axially shorter extension of the adjustment bushing is located on the opposite side. The positive end of the axially shorter extension abuts against the positive end of the axially longer extension of the adjacent adjustment bushing. A spring element which engages on the end-side positive end of the longer extension can thus simultaneously move all adjustment bushings into the programming position in which the adjustment bushings are decoupled from the number wheel. The positive end of the adjustment bushing on the other end side can be supported on a transverse leg of the programming slide in order to load the programming slide into the programming position.

[0016] It is considered advantageous if the spring element loaded on the axially successive adjustment bushings loads the blocking element into an active position in which, by means of the manipulation of the manipulation element, the zero position is prevented so that the zero position can only occur intentionally when a new opening code is stored by the programming element moving the manipulation element into the manipulated position after the manipulation element has been manipulated.

[0062] Figure 45 is a view similar to Fig. 1, but the key is inserted into the key channel of the additional lock 38. Figure 44 DETAILED DESCRIPTION The device shown in the figures is a combination lock. The combination lock has a housing 1 in which a manipulating device is arranged. The manipulating device has a knob 11 which is rotatably supported in the housing 1. The knob 11 has an additional lock 38 which has a lock cylinder 41 with a key channel into which a suitable key can be inserted in order to pull back a latch 24 by turning the lock cylinder 41 and a manipulating element 39 which is coupled with the lock cylinder 41. For this purpose, a manipulating pin 39' of the manipulating element 39 acts on a protrusion 40 of the latch 24 in order to pull the latch 24 from the rest position shown in Fig. 1 into the position shown in Fig. 2.

[0063] Figure 2 ​​​​​​​The shown lock blocking position is pulled back. The spring 27, which is a helical compression spring in the exemplary embodiment, is tensioned. The latch 24 can also be moved against the restoring force of the spring 27 by radial pressure.

[0064] The knob 1 has an upper base body 50 and a lower base body 49. On the outer wall of the upper base body 50 of the knob 11 there is a control body which is designed as a control sleeve 10. The control sleeve 10 is torsionally connected to the base body 50 of the knob 11. For this purpose, radial wings of the control sleeve 10 project into recesses in the base body 50. The control sleeve 10 is axially movable in the direction of the axis of rotation of the knob 11. This takes place against the restoring force of a spring element 17. The control sleeve 10 can be supported on the upper end face of the lower base body 49 which is torsionally connected to the upper base body 50. This can take place by means of a lower edge ridge 18'.

[0065] The control sleeve 10 has a recess 9 which is open towards the lower edge ridge 18' of the control sleeve 10. A cylindrical peripheral surface 18 is connected on the recess 9 in the peripheral direction with respect to the axis of rotation and has a trapezoidal base surface. A control curve device with an inclined control curve 19 adjoins the cylindrical peripheral surface 18. In the exemplary embodiment, the control curve device 2 has a roof-like control curve 19. The control curve is formed by the edge of a recess 48 with a base surface 48'.

[0066] The control sleeve 10 also has two diametrically opposite control projections 35, each of which has a control bevel 34, 34' which extends inclined to the plane of rotation of the knob 11 and a control side surface 35' which lies in the plane of rotation of the knob 11.

[0067] The shaft 30 is supported in the housing 1, which supports four axially successive adjustment bushes 3. The adjustment bushes 3 can be rotated independently of one another about the shaft 30. Each adjustment bush 3 has a central section which forms a notch 28. A heart-shaped curve 33 adjoins this section. The adjustment bush 3 also has a sleeve-shaped extension 13 on which a number wheel 2 is supported. A shorter sleeve-shaped extension 15 is located on the other side. The positive end of the short sleeve-shaped extension 15 rests against the end face of the long sleeve-shaped extension 13. The positive end of the long sleeve-shaped extension 13 of the outer adjustment bush 3 is loaded by a spring element 12 which is supported on the housing wall 31. The positive end of the shorter sleeve-shaped extension 15 of the other outer adjustment bush 3 is supported on a stop 14 of the lateral leg of the programming slide 7.

[0068] The wide side of the adjustment sleeve 3 has a coupling opening 5 into which a coupling pin 4 which belongs to the number wheel 2 of the adjustment sleeve 3 can be inserted in a coupled position, so that the adjustment sleeve 3 is torsionally coupled with the number wheel 2. In a decoupled position, the coupling pin 4 has been completely moved out of the coupling opening 5, so that the adjustment sleeve 3 and the number wheel 2 can be rotated independently of one another about the shaft 30.

[0069] The number wheel 2 has on its circumference the numbers from zero to nine. They also have further heart-shaped curves 32.

[0070] The zero adjuster 21 is supported in the housing 1. The zero adjuster 21 has a shaft 45 about which the zero adjuster 21 can be rotated. The zero adjuster 21 has a handling pin 21' which serves as a lever arm to rotate the zero adjuster 21 about the shaft 45. The zero adjuster 21 has a plurality of reset arms 44 which project in radial direction from the shaft 45 relative to the shaft 45. Every second reset arm 44 cooperates with a heart-shaped curve 32 of the number wheel 2 and / or a heart-shaped curve 33 of the adjustment bushing 3. Since the adjustment bushing 3 is axially displaceable, the heart-shaped curve 33 of the adjustment bushing 3 cooperates only in the decoupling position with the reset arm 44 assigned to it.

[0071] The lower base body 49 of the rotary knob 11 has a control curve 20 which cooperates with the handling pin 21' of the zero adjuster 21 in order to handle the zero adjuster 21 when the rotary knob 11 is rotated. The control curve 20 is formed by two control slopes which are roof-shaped with respect to one another. The control slopes are formed by the walls of a control groove.

[0072] Plate spring elements 46 are also supported in the housing 1 which form spring arms 47 with a projection 47' which cooperates with the number wheel 2 in order to hold the number wheel 2 in different positions.

[0073] A locking mechanism 6 is provided in the housing 1 which can be swung about a shaft 42 as a rocker. The locking mechanism 6 has a recess 25 into which a locking bolt 24 can be inserted in a locking position. The locking mechanism 6 is held in a release position by a spring element 36 in which the recess 25 is not located in the same rotational plane as the rotary plane of the locking bolt 24 so that the rotary knob 11 can be rotated. In the locking position of the locking mechanism 6, the recess 25 is located in the rotary plane of the locking bolt 24 so that the rotary knob 11 cannot be rotated. The recess 25 is adjacent to a side face 26, 26' respectively, against which the locking bolt 24 can strike when the rotary knob enters the locking position in the blocking position of the locking mechanism 6. Depending on the direction of rotation of the rotary knob 11, the locking bolt can then slide on one of the side faces 26, 26'.

[0074] The locking mechanism 6 has a hump 29 which is assigned to each adjustment sleeve 3, which can be inserted into a corresponding recess 28 of the adjustment sleeve 3, if all adjustment sleeves 3 are in the operating position in which the recess 28 points to the hump 29, the locking mechanism 6 can assume its release position. As soon as one of the adjustment bushings 3 is not in this position, the locking mechanism 6 assumes its blocking position. The humps 29 are formed by arms 43 respectively.

[0075] The locking mechanism 6 cooperates with a push rod 22 which acts on an arm of the locking mechanism 6 which constitutes a recess 25. The lower end of the push rod 22 can be supported on this arm. The upper end of the push rod 22 which extends parallel to the axis of rotation of the knob 11 can be loaded by the control bevels 34, 34' and / or the control bevel 35 of the control projection 35.

[0076] The number wheel 2 is located in the space of the programming slide 7 which is delimited by the frame legs 37. The programming slide 7 forms a stop 14 by the transverse legs on which the adjustment bush 3 can be supported. The stop 14 is loaded by the spring element 12 which is supported on the housing wall 31 by the axially forward and rearward arranged adjustment bush 3. The programming slide 7 has a projection 8 at its end which is adjacent to the knob 11 and a switch knob 16 which projects from the housing at its end which is remote from the knob 11. The programming slide 7 can be moved in a direction which is parallel to the shaft 30 or transverse to the axis of rotation of the knob 11.

[0077] The projection 8 has two roof-like bevels 8' opposite one another on its outermost free end which can cooperate with the control curve 19 of the recess 48.

[0078] The function of the device is as follows: in the Figures 1 to 7 The shown open position of the lock, the adjustment bush 3 is in a position which is uncoupled from the number wheel 2. The adjustment bush 3 occupies its release position in which the projection 9 of the locking mechanism 6 engages in the recess 28 of the adjustment bush 3 and thus holds the adjustment bush 3 in its release position. The number wheel 2 can be adjusted relative to the adjustment bush 3 so that an individual opening code can be set. The adjustment bush 3 is held in the uncoupled programming position by the spring element 12.

[0079] The projection 8 of the programming slide 7 engages in the recess 9 of the control sleeve 10 so that it is prevented from rotating. Since the control sleeve 10 is torsionally connected to the knob 11, the knob 11 cannot be rotated in the Figures 1 to 7 The shown programming position. The knob 11 cannot therefore be turned.

[0080] Figure 4 It is shown how the locking mechanism 6 engages with the arch 29 into the recess 28 of the adjustment sleeve 3 and thus occupies the release position.

[0081] If the switch knob 16 is moved away from the knob 11 starting from this programming position, the programming slide 7 is moved from the programming position into the operating position in which the projection 8 has moved out of the recess 9. In this position, the knob 11 can be turned. When the programming slide 7 is moved from the programming position into the Figure 8 and Figure 9The position shown, the adjustment bush 3 is coupled to the number wheel 2, thus determining the opening code. Therefore, the rotatability of the knob 11 is only achieved when the programming slide 7 has been intentionally moved into the operating position. This prevents the device from being programmed with a random, unintentionally set code by accident.

[0082] After a slight rotation of the knob 11, the handling pin 21' of the zero adjuster 21 enters the region of the control curve 20. As Figure 11 and Figure 12 shown, the handling pin 21' slides along the control curve 20 and moves the zero adjuster 21 such that every second arm 44 of the zero adjuster 21 engages in the heart-shaped cam 32 of the number wheel 2 in order to move the number wheel 2 together with the adjustment bush 3 coupled to the number wheel 2 into the neutral position. See Figure 14 and 15 .

[0083] With a slight preliminary movement, the control ramp 34 of the control projection 35 loads the upper end of the push rod 22, which is supported on a rocker of the locking mechanism 6, in order to move the arch 29 out of the recess 28 before the zero position. In conjunction therewith, the locking mechanism 6 moves into its locked position, such that the recess 25 is located in the rotational plane of the locking bolt 24. When the knob 11 is further turned in the direction of the locked position, the locking bolt 24 slides along the side faces 26, 26' and is moved against the restoring force of the spring 27 until it can enter the recess 25 when the locked position is reached (see Figure 17 and 19 ).

[0084] Before the locked position is reached, the end face of the protrusion 8 passes over the edge ridge of the recess 48 (see Figure 18 ). The edge ridge forms one of the control curves 19. The width of the edge ridge corresponds to the depth of the recess 48. When the edge ridge is passed (see Figure 21 ), the programming slide 7 is slightly moved in the direction of its programming position. However, the displacement is so small that the coupling pin 4 cannot be moved out of the coupling opening 5. Therefore, the coupling position between the number wheel 2 and the adjustment bush 3 is maintained.

[0085] In the locked position (see Figures 20 to 23 ), the front end of the protrusion 8 rests on the bottom face 48' of the recess 48 formed by the two control curves 19. From this position, the knob can be rotated in both the clockwise and the counterclockwise direction into the direction of the open position.

[0086] In order to open the lock, the additional lock 38 must be manipulated with a suitable key such that the locking bolt 24 is retracted, or the number wheel 2 must be brought into a rotational position corresponding to the opening code such that the locking mechanism 6 is in the released position.

[0087] Directly after the knob 11 begins to be rotated in the direction of the open position (seeFigure 24 ), the free end of the protrusion 8, i.e. in particular the bevel 8', abuts against a control curve 19, which extends obliquely with respect to the plane of rotation of the knob 11. As a result, the control sleeve 10 is moved against the restoring force of the spring element 17 until the free end of the protrusion 8 reaches under the cylindrical peripheral surface or the lower edge ridge 18' of the control sleeve 10 (see Figure 25 ). The latter in turn leads to a movement of the programming slider 7 in radial direction with respect to the axis of rotation of the knob 11 towards the axis of rotation. The driving force is the spring 12 loaded on the adjustment bush 3, so that the adjustment bush 3 reaches a decoupled position with respect to the number wheel 2 (see Figure 26 ).

[0088] When the knob 11 is turned further from this rotational position, the push rod 22 can run under the control protrusion 35, for example to pivot the locking mechanism 6.

[0089] When the knob 11 is turned further, the handling pin 21 passes the control curve 20, thereby handling the zeroer 21. Since the reset arm 44 now lies in the region of the heart-shaped curve 33 of the adjustment bush 3, not only the number wheel 2 (see Figure 28 ) is moved into the neutral position, but also the adjustment bush 3 (see Figure 29 ) is moved into the release position.

[0090] When the knob 11 reaches its open position at the end of the rotational movement, the protrusion 8 lies under the recess 9, so that the control sleeve 10 is brought back by the force of the spring element 17 to the starting position shown in Figure 2 .

[0091] It is an object of the application to improve the handling reliability of the handling device or of the lock according to the application having such a handling device. This avoids unintentional coding with an unintentionally set code by simply handling the knob, i.e. without being noticed by the person setting it. Since the handling element 11 can only be handled from the open position of the lock when the open code is saved, this disadvantage is eliminated.

[0092] The above statements serve to explain the invention covered by the present application as a whole, which improves the prior art at least independently by the following feature combinations, whereby two, more or all of these feature combinations can also be combined, i.e.:
