Description

[0001] The invention relates to a device for controlling the closing sequence of a double-leaf door, a door locking system and a double-leaf door with a passive leaf and a moving leaf.

[0002] Double-leaf doors typically have a fixed leaf and a moving leaf, which are usually rebated. To ensure that the two leaves do not jam due to the rebated position, such doors require a closing sequence control so that the fixed leaf always closes before the moving leaf. This is usually achieved by means of a lock that holds the moving leaf open in a specific position, allowing the fixed leaf to close safely before the moving leaf, and a trigger that deactivates the lock when the fixed leaf is closed.In the case of a double-leaf door which is equipped with door closers for both leaves, the locking is usually implemented by blocking the closing movement of a sliding block which is connected to the respective leaf via a rigid lever along a sliding rail of the door closer, so that the leaf, usually the active leaf, cannot close.

[0003] When a door closer with such a mechanism is mounted on the opposite hinge side, the sliding block, which is movably mounted along the door closer's guide rail, is typically first moved in the opposite direction of its opening direction to a reversal point in the guide rail when the respective leaf is opened from a closed position, and only then is moved in the opening direction. Conversely, when the leaf is closed, the sliding block is first moved to the reversal point, which it reaches shortly before the leaf is fully closed, and then moved back in the opposite direction to the closed position.

[0004] Under certain circumstances, this counter-movement of the sliding block, also known as a "counter-movement stroke," can be blocked by an inadvertently activated lock in a door closer mounted on the opposite hinge. This can happen, for example, if the passive leaf is almost but not fully closed, or if a malfunction occurs. In this case, the lock blocks the initial opening movement of the sliding block between the closed position and the reversal point, preventing the sliding block from moving to the reversal point. The active leaf cannot then be opened.

[0005] EP 2 208 846 A2 relates to a device for controlling the closing sequence of double-leaf swing doors by means of a slide rail closer. When the inactive leaf is open, a holding part blocks the closing movement of the active leaf in a standby position until the inactive leaf is at least almost closed. For this purpose, the active leaf is equipped with a holding part which holds it in the standby position. The inactive leaf is equipped with a release part which transfers the holding part of the active leaf from a blocked position to a movable position. For at least one of the two parts, the holding part or the release part, not just a sliding block is used, but a part which is movable relative to it and driven by the closing movement of a door leaf, which executes a significant movement away from the axis of rotation of the respective door leaf during the relevant angular range of the closing movement of the door leaf.

[0006] It is an object of the present invention to propose a device for closing sequence control, a door closing system and a double-leaf door which prevent an unintentional blocking of the opening movement of the active leaf and have a comparatively simple structure.

[0007] This problem is solved by the subject matter of the independent claims. Advantageous embodiments are the subject matter of the dependent claims.

[0008] The device for closing sequence control according to the invention is intended for a double-leaf door with a fixed leaf and a moving leaf, wherein the moving leaf is provided with a door closer having a lever, and wherein a sliding block connected to the lever is guided in a slide rail, which is movable in the slide rail in an opening direction corresponding to an opening movement of the moving leaf and a closing direction corresponding to a closing movement of the moving leaf, but executes an opposite movement at the beginning of the opening movement of the moving leaf and at the end of the closing movement of the moving leaf. The device for closing sequence control comprises a locking rod movable between a retracted position and an extended position, a blocking mechanism for blocking a retraction movement of the locking rod in order to secure the moving leaf in a locking position,If an opening angle of the passive leaf is greater than a predetermined limit angle, a driver attached to the locking rod, which is driven by the sliding block in a driven state and is decoupled from the sliding block in a released state, and a control lever for rotationally fixed connection to the lever of the door closer, wherein the control lever is designed to perform a rotational movement with the lever during the opening and closing movement of the active leaf and, during the closing movement of the active leaf, to set the driver at a reversal point of the sliding block into its release state due to its rotational movement in order to decouple the driver from the sliding block, so that the driver remains at the reversal point of the sliding block, and wherein the reversal point of the sliding block corresponds to the retracted position of the locking rod.

[0009] If the opening angle of the passive leaf exceeds the predetermined limit angle, the active leaf should be prevented from closing. This is achieved, for example, by means of a mechanical trigger and an actuating device such as a cable pull. The predetermined limit angle is selected to be as small as possible, for example, approximately 2°.

[0010] If the predetermined limit angle is exceeded, the locking mechanism is activated. In this state, the locking rod can be extended toward the extended position, but cannot be retracted, as the locking mechanism blocks the retraction of the locking rod. Thus, when the driver is coupled to the sliding block, the locking rod prevents the active leaf from closing.

[0011] According to the invention, an unintentional blocking of the opening movement is prevented by the driver attached to the locking rod being decoupled from the sliding block at the reversal point during the closing movement. This allows the sliding block to move between the reversal point and the position it assumes when the active leaf is fully closed, decoupled from the driver, and thus decoupled from the locking rod. Therefore, even if the locking rod is unintentionally blocked by the blocking mechanism, the movement of the sliding block in the slide rail is not blocked. Opening the active leaf is thus possible in this decoupled state, regardless of the state of the blocking mechanism and the locking rod.

[0012] The driver has a rotatably mounted switching rocker, wherein the control lever is designed to deflect the switching rocker at the reversal point of the sliding block due to its rotary movement when the active leaf closes, in order to put the driver into the release state. In particular, the control lever is connected to the lever in such a way that it moves with the rotary movement of the lever when closing and opening. The switching rocker rotatably mounted on the driver can be deflected at the reversal point due to the rotary movement of the control lever, whereby the driver is put into the release state and releases the sliding block. As a result, the driver remains at the reversal point, so that the locking rod remains in its retracted position. The sliding block, on the other hand, is moved away from the reversal point as the active leaf continues to close.

[0013] For example, the rocker switch can be designed to accommodate the sliding block underneath it, whereby the sliding block and rocker switch can be moved along the slide rail when coupled. When deflected, the rocker switch assumes the release state, in which the sliding block can be moved out of the rocker switch, so that the sliding block is no longer accommodated under the rocker switch.

[0014] The rocker switch can have a contact section, wherein the control lever is configured to contact the contact section at the reversal point of the sliding block during the closing movement of the active leaf due to its rotational movement, thereby deflecting the rocker switch. In other words, the control lever can move to the contact section at the reversal point due to its rotational movement, thus deflecting the rocker switch. In particular, the control lever can be rotated below the contact section. In this case, the rocker switch can be deflected so that the sliding block can be guided out from under the rocker switch.

[0015] Preferably, the contact section or the control lever is provided with a contact pin, in particular a spring-loaded one, wherein the contact pin and / or the control lever or the contact section have a deflection bevel in their contact area. The deflection bevel can, for example, be provided on an outer edge and be designed as a chamfer. The deflection bevel is advantageous for facilitating contact, in particular for making it easier to slide the contact pin under the contact section during the rotational movement of the control lever.

[0016] In one embodiment, the rocker switch and the control lever can each have a magnet that attracts or repels each other, causing the rocker switch to be magnetically deflected. During the rotational movement, the control lever with its magnet is then rotated into range of the rocker switch and its magnet, causing the rocker switch to be magnetically deflected.

[0017] In In a further embodiment, a leg spring mounted on the rocker switch can be provided, wherein the rocker switch is deflected by actuation of the leg spring by the control lever. For example, a pin can be formed on the rocker switch to which the leg spring is attached. The two legs of the spring can be connected to the control lever on the one hand and to the rocker switch on the other hand in such a way that they deflect the rocker switch when the reversal point of the sliding block is reached.

[0018] Preferably, the rocker switch is preloaded into the engaged state due to gravity. Alternatively or additionally, a spring can be provided that preloads the rocker switch into the engaged state.

[0019] The rocker switch can have a run-on bevel at its free end for deflecting the rocker switch. The run-on bevel has the particular purpose of allowing the sliding block to be moved against the run-on bevel, particularly at the beginning of the opening of the active leaf and in the uncoupled state, thereby deflecting the rocker switch. At the beginning of the opening of the active leaf, the sliding block is initially moved along the slide rail towards the reversal point while being uncoupled from the driver or the rocker switch. If it then presses against the run-on bevel, for example from the outside, the rocker switch is deflected to pick up the sliding block and be coupled with it. During the closing movement, the initially uncoupled sliding block also presses against the run-on bevel to deflect the rocker switch and couple with the rocker switch.

[0020] The driver can have an angle limiter for the rocker switch. This ensures that the rocker switch is only deflected up to the angle limiter.

[0021] The lever and control lever can be mounted on the sliding block with a pivoting bearing. This ensures that they rotate around the sliding block when the active leaf is opened or closed. Ideally, the lever and control lever can be mounted so they can rotate around the same axis of rotation and, for example, share a corresponding bearing bush.

[0022] Preferably, the sliding block entrains the driver at the reversal point during the opening movement of the active leaf. The sliding block and driver are thus coupled together at the reversal point. As the active leaf is opened further, the sliding block entrains the driver, thereby extending the locking bar.

[0023] The blocking mechanism can comprise a clamping element, in particular surrounding the locking rod, which is designed to be tilted to block the retraction movement of the locking rod, to be canted with the locking rod, and to be straightened to release the blocked retraction movement. For example, a mechanical device can be provided to actuate the clamping element. This device is connected to the inactive leaf and is activated when the predetermined limit angle is exceeded or undershot.

[0024] The device can also have a passive leaf-side driver, which in a driving state is driven by a passive leaf-side sliding block and in a release state is decoupled from the passive leaf-side sliding block, and an actuating device for absorbing tensile forces, which is connected to the passive leaf-side driver and which is designed to deactivate the blocking mechanism when the actuating device is under tension and to activate the blocking mechanism when the actuating device is not under tension.In addition, a control lever on the passive leaf side can be provided for rotationally fixed connection to a lever on the passive leaf side of a door closer on the passive leaf side, wherein the control lever on the passive leaf side is designed to execute a rotational movement with the lever on the passive leaf side during the opening and closing movement of the passive leaf and, during the opening movement of the passive leaf, due to its rotational movement, to set the driver on the passive leaf side into its release state at a reversal point of the sliding block on the passive leaf side in order to decouple the driver on the passive leaf side from the sliding block on the passive leaf side, so that the driver on the passive leaf side remains at the reversal point of the sliding block on the passive leaf side, wherein the actuating device is not under tension and the blocking mechanism is activated when the driver on the passive leaf side is at the reversal point of the sliding block on the passive leaf side.

[0025] The invention also relates to a door locking system comprising a door closer for a moving leaf, which has a lever, a sliding block for connecting to the lever, and a slide rail for guiding the sliding block. The door locking system further comprises the above-described device for closing sequence control.

[0026] Furthermore, the invention relates to a double-leaf door with a fixed leaf, a moving leaf, and a door closer for the moving leaf, which comprises a lever, a sliding block connected to the lever, and a slide rail in which the sliding block is guided. The double-leaf door further comprises the above-described device for closing sequence control.

[0027] In the case of a double-leaf door, the slide rail can have a projection extending into the slide rail for moving the driver into the release state, in particular for deflecting the rocker switch, when the locking bar is extended. This projection can, in particular, engage a corresponding recess or bevel in the rocker switch to deflect it. Thus, when the locking bar is extended, the driver is decoupled from the sliding block, allowing the sliding block to move further along the slide rail.

[0028] The invention is described schematically and by way of example below with reference to the drawings, in which: Fig. 1 shows the upper part of a double-leaf door with a passive leaf and a moving leaf, each having a door closer, Fig. 2 shows a longitudinal sectional view showing a locking bar, a driver, a rocker switch, a slide rail, a sliding block, a lever and a control lever according to one embodiment, Fig. 3 shows a driver, a sliding block and a control lever according to one embodiment in cross section, Fig. 4 shows a driver, a sliding block and a control lever according to a further embodiment in cross section, Fig. 5 shows a driver, a sliding block and a control lever according to a further embodiment in cross section, Fig. 6 shows a driver, a sliding block and a control lever according to a further embodiment in cross section, Fig. 7 shows a driver, a sliding block and a control lever according to a further embodiment in cross section and Fig.8A longitudinal sectional view showing a driver, a rocker switch, a slide rail, a slide block, a lever, a control lever, and a cable pull on the inactive leaf side.

[0029] First, Fig. 1 a double-leaf door 100, which has a fixed leaf 101 and a moving leaf 103. The moving leaf 103 is provided with a door closer 11a mounted opposite the hinge. The door closer 11a has a lever 13a, one end of which is rotatably mounted on the door closer 11a and the other end of which is rotatably connected to a Fig. 1 is connected to a sliding block 15 (not visible), which is slidably guided along a slide rail 17a mounted on the door frame. Similarly, the inactive leaf 101 is provided with a door closer 11b mounted opposite the hinge, which correspondingly has a lever 13b which is rotatably mounted on the door closer 11b and whose other end is rotatably connected to a sliding block which is slidably guided along the slide rail 17b mounted on the door frame.

[0030] Fig. 2 shows a longitudinal section through part of the slide rail 17a mounted on the active leaf side. Also visible are the sliding block 15 and the end section of the lever 13a connected to the sliding block 15 via a bearing element 51, namely a pivot bearing. A control lever 31 is connected in a rotationally fixed manner to the same end section of the lever 13a via a further bearing element 53, which connects the control lever 31 coaxially to the bearing element 51, so that the control lever 31 extends away from the axis of rotation of the lever 13a in the opposite direction to the lever 13a, as viewed from the axis of rotation of the bearing element 51. Together, the lever 13a and the control lever 31 are thus connected to the sliding block 15 so as to be rotatable about the same axis, namely the axis of rotation of the bearing element 51, with the control lever 31 representing an extension of the lever 13a.An opening or closing movement of the active leaf 103 thus leads to a movement of the sliding block 15 along the slide rail 17a, to a rotational movement of the lever 13a and thereby also to a corresponding rotational movement of the control lever 31.

[0031] The Fig. 2 The position of the sliding block 15 shown corresponds to an almost completely closed position of the active leaf 103. Due to the installation of the door closer 11a opposite the hinge, when the active leaf is opened, the sliding block 15 initially moves in the opposite direction, which is also referred to as a "counter-rotating stroke". In this case, the sliding block 15, starting from the position shown in Fig. 2 shown position, in a first direction 21 until it reaches a reversal point. From the reversal point, the sliding block 15 performs a movement in a second direction 23 until the active leaf 103 is fully opened. When closing the active leaf 103, however, the sliding block 15 is first moved in the first direction 21 until it reaches the reversal point. Subsequently, the sliding block 15 is again moved in the opposite direction, ie in the second direction 23, until it reaches a position along the slide rail 17a which corresponds to the fully closed position of the active leaf 103. As already mentioned, this position corresponds approximately to the Fig. 2 shown position.

[0032] In addition, Fig. 2 a rigid locking rod 25 with a driver 29 attached thereto, wherein the locking rod 25 is arranged in a guide body 55 so as to be movable relative thereto. The locking rod 25 is basically arranged between a Fig. 2 shown retracted position and one in Fig. 2 to the right in its extended position. However, the retraction movement can be blocked by a blocking mechanism 27, which in the present example is designed as a rod blocking mechanism known per se. The blocking mechanism 27 has a clamping cage 69 in which a clamping element 67 is arranged in a tiltable manner, which engages around the locking rod 25 and is biased by a clamping spring 71 in the direction of its clamping position. The clamping cage 69 rests against an overload spring 65, which can also be designed as a disc spring assembly. The tiltable arrangement of the clamping element 67 is ensured by the fact that the clamping element 67 is mounted on one side on an edge of the clamping cage 69, although this is not visible in the figures. The clamping element 67 consists of a package of several slats in order to achieve secure clamping of the locking rod 25, whereby secure locking of the active leaf 103 is also possible with high leaf weights.Due to the spring load of the clamping spring 71, the clamping element 67 is guided into a position oblique to the direction of displacement of the locking rod 25, whereby the locking rod 25 is canted in the clamping element 67 and the locking rod 25 is arrested or locked. The locking rod 25 can then no longer be moved in the first direction 21, which is shown in . Fig. 2 shown position, namely the fully retracted position, would no longer be possible anyway; however, movement in the first direction 21 is blocked even if the locking rod 25 is not in the fully retracted position. However, the locking rod 25 can still extend in the second direction 23. During a movement in the second direction 23, the clamping element 67 mounted on one side is carried along by the movement of the locking rod 25 and thus straightened.

[0033] The switching of the blocking mechanism 27, i.e. the tilting or straightening of the clamping element 67, can be carried out in particular by a mechanical trigger on the inactive leaf 101 and via an actuating device 73, such as the one shown in Fig. 8 shown cable pull.

[0034] Fig. 8 shows a longitudinal section through part of the slide rail 17b mounted on the passive leaf side. Analogous to the design on the active leaf side, the sliding block 15b and the end section of the lever 13b connected to the sliding block 15b via a bearing element 51b, namely a pivot bearing, can also be seen. A control lever 31b is connected in a rotationally fixed manner to the same end section of the lever 13b via a further bearing element 53b, which connects the control lever 31b coaxially to the bearing element 51b, so that the control lever 31b extends away from the axis of rotation of the lever 13b in the opposite direction to the lever 13b, as seen from the axis of rotation of the bearing element 51b. Together, the lever 13b and the control lever 31b are thus connected to the sliding block 15b so as to be rotatable about the same axis, namely the axis of rotation of the bearing element 51b, with the control lever 31b representing an extension of the lever 13b.An opening or closing movement of the passive leaf 101 thus leads to a movement of the sliding block 15b along the sliding rail 17b, to a rotational movement of the lever 13b and thereby also to a corresponding rotational movement of the control lever 31b.

[0035] If a predetermined limit angle of the inactive leaf 101 is exceeded, for example approximately 2°, the blocking mechanism 27 is activated, preventing the locking rod 25 from retracting. This occurs because the actuating device 73 is loose and no tension is applied to it, as will be described in more detail later. The actuating device 73 is connected to the clamping spring 71 in a generally known manner, such that the clamping spring 71 can relax when the actuating device 73 is loose, the clamping element 67 is tilted by the clamping spring 71 and the locking rod 25 is blocked, and such that the clamping spring 71 is compressed when the actuating device 73 is pulled, so that the clamping element 67 does not jam with the locking rod 25 and the locking rod 25 can move freely in both directions.This connection of the actuating device 73 with the clamping spring 71 can be effected, for example, by means of an intermediate rocker lever, which, however, is not shown in the figures.

[0036] When the blocking mechanism 27 is activated, the active leaf 103 remains in a locked position, allowing the inactive leaf 101 to close first. As soon as the inactive leaf 101 falls below the limit angle and secure closing before the active leaf 103 is ensured, the blocking mechanism 27 is deactivated, allowing the locking rod 25 to retract and the active leaf 103 to close.

[0037] The driver 29 is guided in the slide rail 17a and in the present example has a rocker switch 33 rotatably mounted thereon. The rocker switch 33 is movable due to gravity, but depending on the embodiment also due to a Fig. 4 The spring 45 shown in FIG. 1 preloads the rocker switch 33 into a closed position in which it is approximately horizontally aligned. In this position, the rocker switch 33 rests on a holding portion 59 of the driver 29 and is held in position by the latter. Furthermore, the driver 29 has an angle limiter 49 that limits a deflection movement of the rocker switch 33 relative to the driver 29.

[0038] How Fig. 2 and 4 show, the control lever 31 in the present example is provided with a protruding section 57, which has a deflection slope 39. In addition, Fig. 2 and 4 A contact section 35 is provided on the switching rocker 33 shown.

[0039] When the active leaf 103 closes from the open state, the sliding block 15 coupled to the driver 29 initially moves in the first direction 21. In In this coupled state, the rocker switch 33 takes the sliding block 15, as for example in Fig. 4 shown, below each other. This corresponds to the engaged state of the driver 29. A movement of the sliding block 15 thus leads to a corresponding movement of the driver 29 and the locking rod 25. If the blocking mechanism 27 blocks the retraction movement of the locking rod 25, the active leaf 103 is fixed in its locking position until the inactive leaf 101 falls below the predetermined limit angle, i.e. is almost or completely closed. If the blocking mechanism 27 is not active, or as soon as it is deactivated, the closing movement of the active leaf 103, and thus the retraction movement of the locking rod 25, continues until the sliding block 15 reaches the reversal point. This corresponds to the Fig. 2 shown fully retracted position of the locking rod 25.

[0040] At this point, the lever 13a, and thus also the control lever 31, reaches a rotational position relative to the sliding block 15 and the rocker switch 33 such that the protruding section 57 of the control lever 31 slides under the contact section 35 of the rocker switch 33, which is facilitated by the deflection bevel 39. As a result, the protruding section 57 presses against the contact section 35 from below against the force of the spring 45, so that the rocker switch 33 is deflected and opens; the driver 29 is thus placed in its release state. At the same time, the sliding block 15 changes its direction of movement and is henceforth moved in the second direction 23. Because the rocker switch 33 is open, the sliding block 15 can leave it and slide out of the rocker switch 33. Due to gravity and the force of the spring 45, the rocker switch 33 then closes again.The sliding block 15 is thus decoupled from the driver 29, so that the sliding block 15 is moved in the second direction 23 without moving the driver 29 and extending the locking rod 25. The locking rod 25 remains in the retracted position.

[0041] If the active leaf 103 is now opened again, the sliding block 15 is moved back in the first direction 21 from its initial position, which corresponds to the closed active leaf 103, to the reversal point. Even if the blocking mechanism 27 is inadvertently activated, for example due to a malfunction or because the inactive leaf 101 is slightly open, this does not prevent the sliding block 15 from being moved to the reversal point, since it is decoupled from the driver 29, and thus from the locking rod 25.

[0042] During the opening movement, the sliding block 15 runs against a bevel 47 at the free end of the rocker switch 33, thereby deflecting the rocker switch 33 so that it opens and the sliding block 15 can slide underneath it. As soon as the sliding block 15 is received by the rocker switch 33, it closes automatically, so that the sliding block 15 and the driver 29 are coupled together at the reversal point. The sliding block 15 then reverses its direction of movement into the second direction 23, taking the driver 29 with it.

[0043] In the present example, the slide rail 17a has a projection 19 projecting into the slide rail 17a. The position of the projection 19 corresponds to the extended position of the locking rod 25, which, however, does not correspond to the fully open position of the active leaf 103. The switching rocker 33 is designed such that it has a corresponding bevel or edge and is deflected upon contact with the projection 19 in order to decouple the driver 29 from the sliding block 15. During a further opening movement of the active leaf 103, the sliding block 15 is then moved further in the slide rail 17a, but the driver 29 and the locking rod 25 remain in their position, decoupled from the sliding block 15, until the sliding block 15 reaches the driver 29 again during the closing movement and is coupled to it by deflecting the switching rocker 33 by means of the run-up bevel 47.

[0044] The functionality on the inactive leaf side, which controls the trigger or blocking mechanism 27, is fundamentally similar, so only the differences will be highlighted below. As already described above, there is no locking rod attached to the catch 29b on the inactive leaf side, but rather the actuating device 73, which is designed to absorb tensile forces. As also described above, the actuating device 73 is loose when the inactive leaf 101 is open, i.e., without tension, to activate the blocking mechanism 27, and is tensioned when the inactive leaf 101 is closed, to deactivate the blocking mechanism 27.

[0045] When the passive leaf 101 is completely closed, the driver 29b, a rocker switch 33b and the sliding block 15b are together in the driving state at the position in the slide rail 17b that corresponds to the completely closed position of the passive leaf 101. In In this position, the actuating device 73 is under tension. If the inactive leaf 101 is opened, the sliding block 15b entrains the rocker switch 33b and the driver 29b up to the reversal point. There, the control lever 31b deflects the rocker switch 33b, and the sliding block 15b slides out of the rocker switch 33b, which corresponds to the release state in which the sliding block 15b is decoupled from the driver 29b. The driver 29b consequently remains at the reversal point, so that the actuating device 73 is loose and without tension, and activates the blocking mechanism 27, as previously described. Upon closing, however, the sliding block 15b entrains the driver 29b again at the reversal point, so that the actuating device 73 is under tension again and the blocking mechanism is deactivated.

[0046] Further possible embodiments of the mechanism for deflecting the rocker switch 33 are shown in the Fig. 3 and 5 bis 7 shown.

[0047] For example, Fig. 3 An example in which the rocker switch 33 has a spring-loaded contact pin 37 on which the contact section 35 is formed. When the control lever 31 contacts the contact pin 37 as described above, it pushes the rocker switch 33 upward against the spring force, causing it to deflect.

[0048] Fig. 5 shows a further embodiment in which the rocker switch 33 and the control lever 31 each have a magnet 41a, 41b that attract each other. Upon reaching the reversal point during a closing movement, the attractive force of the magnets 41a, 41b causes the rocker switch 33 to deflect, causing it to open.

[0049] Fig. 6 shows a further embodiment in which the control lever 31 has a link 61 (not shown in detail) for a leg spring 43. The leg spring 43 is mounted on the rocker switch 33. One leg of the leg spring 43 is connected to the link 61; the other leg engages the rocker switch 33 itself. Via the link 61, the leg spring 43 is actuated in the direction of the second direction 23, so that the leg of the leg spring 43 engaging the rocker switch 33 engages the rocker switch 33 and deflects it, namely pushing it upwards in a counterclockwise direction.

[0050] Another embodiment with a leg spring 43 shows Fig. 7 However, an actuating edge 63 is provided here, which actuates a leg of the leg spring 43 perpendicular to the second direction 23. As a result, the second leg of the leg spring 43 deflects the switching rocker 33. Bezugszeichenliste
