In order to increase the operational reliability of the lock or of the actuating device, a programming element (7) is proposed, which, in the programming position, blocks the actuation of the actuating element (11) and which, upon shifting from the programming position into an actuating position in which the setting bushes (3) are coupled to the number wheels (2), releases the blocking of the blocking element (11).

Description

Description Combination lock with code reset function Field of technology

[0001] The invention relates to an actuating device for a closure with adjusting bushings arranged axially one behind the other, each cooperating with a number wheel, which are coupled to each other in a locking position in which the actuation of an actuating element is locked, wherein the adjusting bushings can be brought into a release position in which the actuating element can be actuated by rotating the number wheels into an opening combination, wherein the number wheels are decoupled from the adjusting bushings in a programming position for changing the opening combination. State of the art

[0002] A device of the type described above is described in DE 102014109224 A1. The actuating device is part of a combination lock in which, in an initial position, number wheels are uncoupled from their associated adjusting bushings. The adjusting bushings assume a release position so that a tumbler interacting with the adjusting bushings can also assume a release position. The number wheels can be adjusted relative to their individually assigned adjusting bushings in order to set an opening code. When an actuating element is turned, the adjusting bushings are coupled to the number wheels. At the same time, the number wheels are reset to a zero position, so that the opening code is obscured. To open the lock, the number wheels and the adjusting bushings coupled to the number wheels must be turned.By setting the opening code using the number wheels, the adjusting bushings are moved into their release position so that the access. 31111PCT – 19.04.2024 position releases a bolt and the rotary knob can be turned into the open position.

[0003] Combination locks are also known from DE 102009016854 A1, EP 2419586 B1 and EP 2942457 B1. Summary of the invention

[0004] The invention is based on the object of further developing the combination lock described above in a manner that is advantageous in use.

[0005] The task is solved by a programming element. The programming element can be moved from a programming position to an actuation position. In the programming position, the number wheels are decoupled from their individually assigned adjusting bushings. The adjusting bushings assume their release position. Each adjusting bushing can have an area of ​​influence, which can in particular be formed by a recess. An area of ​​influence of the guard locking device can enter this recess. The area of ​​influence can be a bulge that enters the recess. The guard locking device can be spring-loaded so that the bulge engaging the recess holds the adjusting bushing in the release position.

[0006] The programming element can have a blocking element that prevents the actuation of the actuating element in the programming position. In the programming position, the number wheels can be rotated independently of the setting bushings, so that an opening code can be set by turning the number wheels. The programming element can be moved from the programming position to an actuating position. For this purpose, the programming element can have a switch button with which the program- 31111PCT – 19.04.2024 programming element can be moved relative to a housing of the actuating device. As the programming element is moved into the actuating position, the adjusting bushings are coupled to their associated number wheels in a rotationally fixed manner. As the programming element is moved into the actuating position, the blocking element also moves out of the blocking position, so that the actuating element can be moved from the open position to a locked position. The programming element ensures that the actuating element can only be actuated if a new opening code is intentionally stored by coupling the adjusting bushings to the number wheels. This makes it more difficult for an unwanted opening code to be stored by inadvertently actuating the actuating element after adjusting the number wheels from a zero position.

[0007] The programming element can be a slider. The switch button can be a projection protruding from the housing. The slider can have two frame legs that run parallel to one another and are connected to one another by cross legs that also run parallel to one another. The setting wheels with their associated number wheels can be arranged in this frame formed by the frame legs and the cross legs. The programming element is preferably moved in a direction parallel to the axis about which the setting bushings or number wheels 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 urges the blocking element, which can be a projection, into its blocking position.The projection forming the blocking element can be located in a recess of a control body in the programming position. The control body can be a cylindrical sleeve that is non-rotatably associated with the actuating element. The actuating element is preferably a rotary knob that can be rotated about a rotation axis. 31111PCT – 19.04.2024 It can be rotated. The control element can be assigned to the rotary knob so that it can be displaced in the direction of this axis of rotation. A spring element can be provided to actuate the control element. If the projection of the programming element engages the recess in the control sleeve, the rotary knob cannot be rotated. If the programming element is moved into the actuating position, the projection can emerge from the recess. The rotary knob can now be displaced.

[0008] The control sleeve can have a cylindrical surface that adjoins the recess in the circumferential direction around the rotation axis of the rotary knob. After a slight rotation of the rotary knob from the open position, the projection can rest against this cylindrical surface. This prevents the programming element from shifting from the actuated position back into the programming position. When the rotary knob is rotated from the open position to the locked position, the projection deflects against this cylindrical surface.

[0009] As it is moved from the open position to the locked position, the rotary knob controls a zero-setting device. The zero-setting device has a plurality of reset arms that can engage heart-shaped control cams on the number wheels to return the number wheels to an initial position, for example, a position in which the number zero is displayed. Along with this adjustment of the number wheels, the setting bushings are also adjusted, as they are rotationally coupled to the number wheels. The opening code is thus obscured. As the setting bushings are turned, the bulges of the locking device emerge from the recesses in the setting bushings. To reduce the force required, the locking device, which is preferably in the form of a rocker, is moved from the release position to a locked position immediately before zero-setting.This is done by a plunger which acts on one arm of the rocker and which is controlled by a control cam of the. 31111PCT – 19.04.2024 The plunger can be moved parallel to the rotary knob's axis of rotation and has a first end that engages the arm of the rocker and a second end that rests on a control cam of the rotary knob when the plunger is moved. The rotary knob therefore has a control bevel that is capable of acting on the plunger to pivot the tumbler in an axial direction - relative to the rotary knob's axis of rotation. The control bevel can be formed by a control projection. A control flank can be connected to the control bevel, along which the second end of the plunger can slide when the zero adjuster brings the number wheels to the zero position.

[0010] The zero-setting device can have an actuating pin that can slide along a control cam of the rotary knob. The control cam is designed such that the zero-setting device is actuated both when the rotary knob is rotated from the open position to the locked position and when the rotary knob is rotated from the locked position to the open position.

[0011] The tumbler can have a recess into which a bolt arranged in the rotary knob engages. The bolt can deflect radially inward relative to the rotary knob's rotation axis against the restoring force of a spring. It can thus enter the recess even when the tumbler is in the locked position. To do this, a bolt head can slide along a flank of the tumbler and deflect into a recess in the rotary knob.

[0012] An additional lock can be provided, which, when activated, actively pulls the bolt out of the recess in the tumbler, allowing the rotary knob to be turned even if the opening code is incorrectly set. The additional lock has a locking cylinder located in the rotary knob. 31111PCT – 19.04.2024

[0013] If the rotary knob is turned from the locked position to the open position, either with the opening code correctly set or with the bolt retracted, a control cam arrangement associated with the control sleeve comes into effect. This control cam arrangement has a control cam that is inclined relative to the rotational plane of the rotary knob. This cam interacts with the projection of the programming slide in such a way that the control sleeve is displaced in the axial direction against the restoring force of the spring acting on it. The projection of the programming slide can have one or more bevels that can slide along the control cam to displace the control sleeve.The projection of the programming slide, or rather the slope formed by it and the control cam, are designed such that immediately after the rotary knob begins to be turned from the locked position, the control sleeve is raised until the projection of the programming slide passes below the lower edge of the control sleeve. This results in the programming slide being moved from the actuated position into the programming position. At the same time, the adjusting bushings are moved from their coupling position to the respective number wheels, which means that the adjusting bushings can be rotated independently of the number wheels. In the locked position, the projection of the programming element can be located in a recess in the outer wall of the control body.When entering this recess, the programming element can shift slightly toward the programming position, but not to the extent that the coupling position between the adjusting bushings and the number wheels is lost. The edges of this recess form the control cam, with which the control sleeve is shifted in the axial direction.

[0014] Both the number wheels and the setting bushings have heart-shaped control cams, each of which can interact with a reset arm of the zero-setting device. While the heart-shaped cams of the number wheels in both 31111PCT – 19.04.2024 While the number wheels can be acted upon by the reset arms in both the programming and actuating positions, the heart-shaped curves of the adjusting bushings can only be acted upon by the reset arms in the uncoupled position, which is axially offset from the coupling position. This means that when the rotary knob is turned from the locked position to the open position, not only the number wheels but also the adjusting bushings are moved to an initial position. The number wheels are moved to the zero position, and the adjusting bushings to the release position.

[0015] The adjusting bushings are arranged axially displaceably on an axis. Both ends of the axis are mounted in the housing. The adjusting bushings have a central section that forms the heart-shaped curve and has the bulge axially adjacent to it. The number wheel assigned to the adjusting bushing sits on a sleeve-shaped extension. This wheel has coupling pins extending in the axial direction that can enter coupling openings in the adjusting bushings. An axially shorter extension of the adjusting bushing is located on the opposite side. One end of the axially shorter extension rests against one end of the axially longer extension of an adjacent adjusting bushing. A spring element that acts on one end of a longer extension can thus move all adjusting bushings simultaneously into the programming position, in which the adjusting bushings are decoupled from the number wheels.A front end of a setting bushing at the other end can be supported on a cross leg of the programming slide in order to force the programming slide into the programming position.

[0016] It is considered advantageous if a spring element acting on the axially arranged adjusting bushings forces a blocking element into an active position in which a zero position is prevented by actuating an actuating element, so that the zero position can only be achieved after actuating the actuating element if 31111PCT – 19.04.2024 A new opening code is stored by moving a programming element into an actuating position.

Description of the embodiments

[0018] The device shown in the drawings is a combination lock. The combination lock has a housing 1 in which an actuating device is arranged. The actuating device has a rotary knob 11 that is rotatably mounted in the housing 1. The rotary knob 11 has an additional lock 38 that has a cylinder core 41 with a keyway into which a suitable key can be inserted in order to retract a bolt 24 by turning the cylinder core 41 and an actuating element 39 coupled to the cylinder core 41. For this purpose, an actuating pin 39' of the actuating element 39 engages a projection 40 of the bolt 24 in order to retract the bolt 24 from the locked position shown in Figure 2. In this process, a spring 27, which in the exemplary embodiment is a helical compression spring, is tensioned. The latch 24 can also be displaced by radial pressure against the restoring force of the spring 27.

[0019] The rotary 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 rotary knob 11 is a control body, which is designed as a control sleeve 10. The control sleeve 10 is connected in a rotationally fixed manner to the base body 50 of the rotary knob 11. For this purpose, radial wings of the control sleeve 10 protrude into recesses in the base body 50. The control sleeve 10 can be axially displaced in the direction of the rotational axis of the rotary knob 11. This occurs against the restoring force of a spring element 17. The control sleeve 10 can be 31111PCT – 19.04.2024 an upper end face of the lower base body 49, which is connected in a rotationally fixed manner to the upper base body 50. This can be done with a lower edge 18'.

[0020] The control sleeve 10 has a recess 9 open to the lower edge 18' of the control sleeve 10. Adjacent to the recess 9 in a circumferential direction relative to the axis of rotation is a cylindrical surface 18 and has a trapezoidal outline. Adjacent to the cylindrical surface 18 is a control cam arrangement having an inclined control cam 19. In the exemplary embodiment, the control cam arrangement has two control cams 19 arranged in a roof-like manner. The control cams are formed by the edges of a recess 48 having a bottom surface 48'.

[0021] The control sleeve 10 also has two diametrically opposed control projections 35, each of which has a control slope 34, 34' running obliquely to a rotational plane of the rotary knob 11 and a control flank 35' lying in the rotational plane of the rotary knob 11.

[0022] An axle 30 is mounted in the housing 1, which supports four adjusting bushings 3 arranged axially one behind the other. The adjusting bushings 3 can be rotated independently of one another about the axle 30. Each adjusting bushing 3 has a central section which forms an indentation 28. A heart-shaped curve 33 is adjacent to this section. The adjusting bushing 3 also has an extension 13 which has a sleeve shape and on which a number wheel 2 is mounted. A shorter sleeve-shaped extension 15 is located on the other side. One end of a short sleeve-shaped extension 15 rests against one end of a long sleeve-shaped extension 13. One end of a long sleeve-shaped extension 13 of an outer adjusting bushing 3 is acted upon by a spring element 12 which is supported on a housing wall 31. The front end of a shorter sleeve-shaped extension 15 of another 31111PCT – 19.04.2024 The outer adjusting bushing 3 is supported on a stop 14 of a cross leg of a programming slide 7.

[0023] A broad side surface of the adjusting bushing 3 has coupling openings 5 ​​into which coupling pins 4 of the number wheel 2 associated with the adjusting bushing 3 can engage in a coupling position, so that the adjusting bushing 3 is rotationally fixedly coupled to the number wheel 2. In a decoupled position, the coupling pins 4 are completely protruded from the coupling openings 5, so that the adjusting bushings 3 and the number wheels 2 can be rotated independently of one another about the axis 30.

[0024] The number wheels 2 have numbers from zero to nine on their circumference. They also have an additional heart-shaped curve 32.

[0025] A zero adjuster 21 is mounted in housing 1. The zero adjuster 21 has an axis 45 about which the zero adjuster 21 can be rotated. The zero adjuster 21 has an actuating pin 21' that acts as a lever arm to rotate the zero adjuster 21 about the axis 45. The zero adjuster 21 has a plurality of reset arms 44 that protrude from the axis 45 in the radial direction - relative to the axis 45. Every second of the reset arms 44 interacts with the heart-shaped cam 32 of the number wheel 2 or with the heart-shaped cam 33 of the adjusting bushing 3. Since the adjusting bushing 3 is axially displaceable, the heart-shaped cam 33 of an adjusting bushing 3 only interacts with its associated reset arm 44 in the uncoupled position.

[0026] The lower base body 49 of the rotary knob 11 has a control cam 20, which interacts with the actuating pin 21' of the zero adjuster 21 to actuate the zero adjuster 21 upon rotation of the rotary knob 11. The control cam 20 consists of two control cams arranged in a roof-like manner. 31111PCT – 19.04.2024 bevels. The control bevels are formed by the walls of a control groove.

[0027] In the housing 1, a leaf spring element 46 is also mounted, which forms spring arms 47 having projections 47' that interact with the number wheels 2 to hold the number wheels 2 in different positions.

[0028] Arranged in the housing 1 is a tumbler 6 which can be pivoted about an axis 42 as a rocker. The tumbler 6 has a recess 25 into which the bolt 24 can engage in the locked position. The tumbler 6 is held by a spring element 36 in a release position in which the recess 25 is not in the same plane of rotation of the rotary knob 11 as the bolt 24, so that the rotary knob 11 can be rotated. In a locked position of the tumbler 6, the recess 25 lies in the plane of rotation of the bolt 24, so that the rotary knob 11 cannot be rotated. Flanks 26, 26' are adjacent to the recess 25, against which the bolt 24 can strike when the rotary knob is moved into the locked position in a locked position of the tumbler 6. Then, depending on the direction of rotation of the rotary knob 11, the bolt can slide off one of the flanks 26, 26'.

[0029] The tumbler 6 has a bulge 29 assigned to each adjusting bushing 3, which can engage the respective indentation 28 of the adjusting bushing 3. If all adjusting bushings 3 are in an operating position in which the indentations 28 point toward the bulges 29, the tumbler 6 can assume its release position. The tumbler 6 assumes its locked position as soon as one of the adjusting bushings 3 is not in this position. The bulges 29 are each formed by arms 43. 31111PCT – April 19, 2024

[0030] The tumbler 6 interacts with a plunger 22, which engages the arm of the tumbler 6, which forms the recess 25. A lower end of the plunger 22 can rest on this arm. An upper end of the plunger 22, which extends parallel to the rotational axis of the rotary knob 11, can be acted upon by the control slope 34, 34' or the control flank 35' of the control projection 35.

[0031] The number wheels 2 are located in a space of a programming slide 7 delimited by frame legs 37. The programming slide 7 forms the stop 14 with a transverse leg, against which the adjusting bushing 3 can rest. The stop 14 is acted upon by the spring element 12 supported on the housing wall 31 via the adjusting bushings 3 arranged axially one behind the other. The programming slide 7 has a projection 8 at its end adjacent to the rotary knob 11 and a switching button 16 protruding from the housing at its end remote from the rotary knob 11. The programming slide 7 can be displaced in a direction parallel to the axis 30 or transverse to the axis of rotation of the rotary knob 11.

[0032] The projection 8 has at its outermost free end two slopes 8' which are arranged in a roof-like manner and which can interact with the control curves 19 of the recess 48.

[0033] The device functions as follows: In the open position of the lock, as shown in Figures 1 to 7, the adjusting bushings 3 are in a position decoupled from the number wheels 2. The adjusting bushings 3 assume their release position, in which the bulges 9 of the locking mechanism 6 engage the indentations 28 of the adjusting bushings 3 and thus hold the adjusting bushings 3 in their release position. The number wheels 2 are adjustable relative to the adjusting bushings 3, allowing an individual 31111PCT – 19.04.2024 The opening code can be set. The adjusting bushings 3 are held in the uncoupled programming position by the spring element 12.

[0034] The projection 8 of the programming slide 7 engages in the recess 9 of the control sleeve 10, thus blocking its rotation. Since the control sleeve 10 is connected to the rotary knob 11 in a rotationally fixed manner, the rotary knob 11 cannot be rotated in the programming position shown in Figures 1 to 7. The rotary knob 11 therefore cannot be rotated.

[0035] Figure 4 shows how the tumbler 6 engages with the bulge 29 into the indentation 28 of an adjusting bush 3 and thus assumes a release position.

[0036] If, starting from this programming position, the switching button 16 is removed from the rotary knob 11, the programming slide 7 is moved from the programming position into an actuation position in which the projection 8 has protruded from the recess 9. In this position, the rotary knob 11 can be rotated. During the movement of the programming slide 7 from the programming position to the position shown in Figures 8 and 9, the setting bushings 3 are coupled to the number wheels 2, so that the opening code is fixed. The rotatability of the rotary knob 11 is thus only achieved when the programming slide 7 has been deliberately moved into the actuation position. This prevents the device from being inadvertently programmed with a random, unintentionally set code.

[0037] After a slight rotation of the rotary knob 11, the actuating pin 21' of the zero adjuster 21 enters the area of ​​the control cam 20. As Figures 11 and 12 show, the actuating pin 21' slides along the control cam 20 and displaces the zero adjuster 21 such that every second arm 44 31111PCT – 19.04.2024 of the zero adjuster 21 engages a heart-shaped cam 32 of the number wheel 2 to move the number wheel 2, together with the adjusting bushing 3 coupled to the number wheel 2, into a neutral position. This is illustrated in Figures 14 and 15.

[0038] With a slight advance, the control bevel 34 of the control projection 35 acts on the upper end of the plunger 22, which is supported on the rocker arm of the tumbler 6, in order to displace the bulge 29 out of the indentation 28 before zeroing. Along with this, the tumbler 6 is displaced into its locked position, so that the recess 25 lies in the rotation plane of the bolt 24. Upon further turning the rotary knob 11 towards the locked position, the bolt 24 slides along the flank 26, 26' and displaces against the restoring force of the spring 27 until it can enter the recess 25 upon reaching the locked position (see Figures 17 and 19).

[0039] Shortly before reaching the locking position, the end face of the projection 8 overruns an edge of the recess 48 (see Figure 18). This edge forms one of the control cams 19. The width of the edge corresponds to the depth of the recess 48. When it overruns the edge (see Figure 21), the programming slide 7 is displaced slightly toward its programming position. However, the displacement is so small that the coupling pins 4 cannot emerge from the coupling openings 5. The coupling position between the number wheels 2 and the adjusting bushings 3 is thus maintained.

[0040] In the locked position (Figures 20 to 23), the front end of the projection 8 rests on a bottom surface 48' of the recess 48 formed by the two control cams 19. From this position, the rotary knob can be turned both clockwise and counterclockwise toward an open position. 31111PCT – April 19, 2024

[0041] To open the lock, either the additional lock 38 must be operated with a suitable key so that the bolt 24 is retracted or the number wheels 2 must be brought into a rotational position corresponding to the opening code so that the tumbler 6 assumes its release position.

[0042] Immediately after the rotary knob 11 begins to rotate toward the open position (see Figure 24), the free end of the projection 8, in particular the bevel 8', comes into contact with the control cam 19, which runs diagonally relative to the plane of rotation of the rotary knob 11. This causes the control sleeve 10 to shift against the restoring force of the spring element 17 until the free end of the projection 8 passes below the lower edge 18' of the cylinder surface or of the control sleeve 10 (see Figure 25). The latter, in turn, causes the programming slide 7 to shift radially toward the rotation axis, relative to the rotation axis of the rotary knob 11. The driving force is the spring 12 acting on the adjusting bushings 3, so that the adjusting bushings 3 move into a position decoupled from the number wheels 2 (see Figure 26).

[0043] When the rotary knob 11 is turned further from this rotary position, the plunger 22 can pass under the control projection 35 in order, for example, to pivot the locking device 6.

[0044] As the rotary knob 11 is turned further, the actuating pin 21 passes through the control cam 20, thus actuating the zero setting device 21. Since the reset arms 44 are now located in the area of ​​the heart-shaped curves 33 of the adjusting bushings 3, not only are the number wheels 2 (see Figure 28) moved to the neutral position, but the adjusting bushings 3 (see Figure 29) are also moved to the release position. 31111PCT – April 19, 2024

[0045] When the rotary knob 11 reaches its open position at the end of its rotational movement, the projection 8 lies under the recess 9, so that the control sleeve 10 is brought back into the starting position shown in Figure 2 by the force of the spring element 17.

[0046] The invention achieves an improved operating reliability of an actuating device or a closure according to the invention that has such an actuating device. It prevents the inadvertent coding, simply by operating the rotary knob, with a code that was not intentionally set, i.e., one that was not memorized by the person setting it. This disadvantage is eliminated by the fact that the actuating element 11 can only be actuated from an open position of the closure if the opening code is stored.
