The adjustment element is connected via a first coupling (23) for actuating a first locking device (10a) and via a second coupling (24) for actuating a second locking device (10b), such that a movement of the adjustment element (25) about a rotation axis (26) can be converted into a displacement of the two couplings (23, 24) by means of a slide control (K) having mutually corresponding control pegs (29, 30) and bearing grooves (32, 33). The adjustment element (25) with the control pegs (29, 30) is at least partially inserted between the two at least partially overlapping and displaceable couplings (23, 24) relative to the adjustment element (25). The control pegs (29, 30) are at least partially inserted into the bearing grooves on the couplings (23, 24).

Description

Technical Field

[0001] This invention relates to a control mechanism for at least partially asynchronously operating two locking devices of an airflow adjustment assembly for a vehicle. Furthermore, the invention also relates to an airflow adjustment assembly for a vehicle having such a control mechanism. Background Technology

[0002] The main drag coefficient (C) that affects energy consumption in motor vehicles at higher speeds is the flow resistance coefficient or frontal drag coefficient. W The value primarily depends on its "streamlined shape". Further improvements can be achieved by temporarily closing the vehicle openings necessary for air intake. For this purpose, airflow adjustment components have long been established at the front end. By placing the airflow adjustment component upstream of at least one component, the loading of that component on the airflow during vehicle movement can be effectively adjusted. Typically, this can be used to supply flowing air to components such as heat exchangers and / or cooling elements to ensure, for example, cooling of the motor, vehicle interior space, and / or battery. As the airflow adjustment component closes further, the proportion of vortices formed by the openings can be achieved, thereby enabling favorable calming of the flow acting on the vehicle. Thus, air is discharged in an improved manner through the shape of the vehicle. Especially when using an internal combustion engine, its harmful emissions can also be reduced. Furthermore, such airflow adjustment components have been used at low speeds to accelerate the heating process of the drive unit by correspondingly reducing the airflow.

[0003] Modern vehicle concepts often feature two overlapping air intakes, the openings of which can be altered simultaneously or separately as needed via an airflow adjustment assembly. The airflow adjustment assembly used for this purpose has two locking devices, each corresponding to one of the two air intakes. Each locking device has at least one plate, the cross-section of which can be changed by pivoting the plate. Separate operation of the two locking devices is often achieved using two actuators. A more economical and easier-to-construct variant can be achieved with a single actuator, which is then coupled to both locking devices, for example, via a suitable linkage.

[0004] Therefore, for example, DE102017219420A1 describes a throttle device having a frame assembly that defines an opening section. The throttle device is intended for installation on a motor vehicle to adjust the flow of cooling air, for example, for a heat exchanger that can be loaded with cooling air. The frame assembly is divided into a first frame section and a second frame section that extends the opening section into a passageway. At least one piece pivotally supported on the frame assembly allows for changes in the cross-sectional area of ​​the flow-through opening of the throttle device in various driving conditions. To achieve a as-sealable connection as possible to the surrounding components of the corresponding motor vehicle, the second frame section is assembled from individual frame elements pivotally mounted on the first frame section.

[0005] US10,207,578B2 discloses a locking system for a radiator grille of a motor vehicle, comprising a multi-piece frame. The frame defining the opening sections has an upper frame section and a lower frame section spaced parallel to the upper frame section, the ends of which are interconnected via one of two end caps. A motor housing containing an actuator is disposed within this frame, and multiple plates extend laterally from the motor housing to the two end caps. The plates are rotatably supported, allowing their positioning angles to be changed via the actuator. The interlocking components of the frame via plug connections and the motor housing, which can be inserted into the frame, enable the disassembly and transport of the locking system. Frame sections of varying lengths allow for modular adaptation of the locking system to the available assembly dimensions of the corresponding motor vehicle. By using two frames, two overlapping opening sections can be defined, and the plates for locking these opening sections can be operated by a single actuator. Therefore, the connecting rod positioned between the two frames transmits the adjusting force, which is applied via an actuator to a piece supported in one of the frames, to a piece supported in the other frame.

[0006] US8,733,484B1 discloses another locking system for a motor vehicle cooler grille. This locking system includes two opening sections, each equipped with a blade assembly. A first blade assembly is coupled to an actuator, while a second blade assembly is operatively connected to the first blade assembly via a linkage. The blade assemblies are configured to pivot from a closed position to an opposite open position. For this purpose, the positioning of the blades in the first blade assembly can be changed by the actuator and transmitted via the linkage to the blades of the second blade assembly. To compensate for possible manufacturing defects, the linkage has a compensating spring to prevent premature actuator shut-off due to resistance arising from uneven arrival of one blade assembly at the closed position.

[0007] DE102017222678A1 and US10,421,352B2 also disclose a locking system for a radiator grille in a motor vehicle. Unlike the aforementioned systems, these systems allow for independent operation of two sections. For this purpose, a roller-shaped adjusting element rotatable via an actuator is provided, the roller having two slots on its circumferential surface. Each section of the grille is operatively connected to the adjusting element via a longitudinally sliding coupling, each coupling being engaged in one of the two slots via a control pin. Straight segments of the corresponding slots, arranged in a sequence with changing direction, constitute a chute control device, such that rotation of the adjusting element causes a corresponding displacement of the control pin and its connected coupling. Due to the relative extension of the two slots, the sections can occupy four different combinations of operating positions, in which the two sections simultaneously or alternately close or open.

[0008] The main advantage lies in achieving a compact, lightweight, and ultimately economical construction using components achievable with a single actuator. The constant synchronous operation of the two locking devices correspondingly limits the achievable effect. In contrast, operating the locking devices at least partially asynchronously, i.e., completely alternately or only partially simultaneously, offers advantages. Considering the wind loads acting on the locking devices, particularly at higher speeds, the mechanism used in this case must be able to transmit sufficiently high forces to ensure the pivoting of its plates and maintain the position they thus occupy. Summary of the Invention

[0009] In this context, the object of the present invention is based on: extending the control mechanism of two locking devices for at least partially asynchronously operating an airflow adjustment assembly and an airflow adjustment assembly for a vehicle equipped with the control mechanism, so that they can achieve the most robust and compact design possible in addition to an economical construction.

[0010] The objective is achieved by a control mechanism according to the invention and an airflow adjustment assembly according to the invention.

[0011] According to the present invention, a control mechanism is provided for at least partially asynchronously operating two locking devices of an airflow adjustment assembly for a vehicle. The control mechanism includes an adjustment element that is connected to or can be connected to an actuator. The adjustment element is operatively connected via a first coupling member configured to operate a first locking device. Furthermore, the adjustment element is operatively connected via a second coupling member configured to operate a second locking device. These connections result in the movement of the adjustment element about a rotation axis being converted into displacement of the two coupling members by a slide control device. For this purpose, the slide control device itself has corresponding control pins and support grooves. According to the present invention, the control pin is located on the adjustment element, and the support groove is located on the coupling member. The adjustment element is inserted between two coupling members that are at least partially overlapped and displaceable relative to the adjustment element, such that the control pin of the adjustment element is at least partially engaged in the support groove of the coupling member.

[0012] The advantage thus obtained is the very compact structure of the control mechanism according to the invention. Therefore, the regulating force originating from the actuator can be transmitted to the two locking devices, particularly sequentially, along the shortest possible path. This results in an economic advantage because the controllable area is increased and the regulating force originating from the actuator is limited. Conversely, wind loads acting on the locking devices, especially at high speeds, are supported on the same short path, without adverse spring performance due to long and consequently less stiff components or / and the "spreading" of the forces that can be absorbed. Furthermore, such wind loads can also be absorbed separately by the actuators. Moreover, when the controllable area and the regulating force originating from the actuators remain constant, a generally larger wind load can also be absorbed. Generally, it is possible to separate the regulating forces of the actuators, thereby increasing the controllable area and improving the absorbable wind load or maximum flow velocity, or conversely, to determine the size of the actuators to be smaller, that is, to have a smaller regulating force.

[0013] In a preferred embodiment of the basic concept of the invention, the control bolt of the adjusting element can be offset from the longitudinal direction of its rotation axis. Furthermore, the control bolt can be positioned on opposite sides of the adjusting element. In this way, the adjusting element inserted between the two couplings is connected laterally to the support grooves of the couplings via its control bolt. Because these components are close to each other, the couplings are achieved with overall rigidity and precise control via the adjusting element. The correspondingly short length of the control bolt enables the transmission of a large force. Thus, undesirable elastic behavior or even structural failure due to dynamic overload is minimized.

[0014] Advantageously, the two control pins of the adjusting element can extend far apart from each other in a plane intersecting with the rotation axis of the adjusting element. In other words, the control pins and the rotation axis coexist in a fictitious plane. In particular, when the respective control pins are spaced equidistant from the rotation axis, an ideal force balance occurs regarding the support of the adjusting element via its rotation axis.

[0015] Different designs can be conceived regarding the separate construction of the couplings for accommodating the extension of the support grooves of one of the control bolts. Once the adjusting element undergoes a rotational movement actuated by the actuator, its extension, as part of the chute guide, primarily serves to displace the start and end points of the couplings and their states in between. Preferably, the support groove of each coupling can have a straight section and an arcuate section connected to the straight section. Advantageously, the radius of the arcuate section can be equal to the distance between the corresponding control bolt and the axis of rotation about its respective longitudinal direction. This makes it possible that, as the adjusting element rotates, the corresponding control bolt passes through the arcuate section of the support groove of its coupling without displacement of the coupling. In contrast, the straight section of the support groove connected to the arcuate section can be arranged such that the control bolt, upon reaching the straight section, strikes the edge defining the straight section and is thus supported on the adjusting element as it rotates further, thereby extruding the corresponding coupling from its position, particularly linearly. In this way, the curved sections of the coupling can form areas of the support groove in which there is no reaction to displacement of the coupling when the control bolt of the rotating adjusting element passes through. Conversely, the straight sections of the coupling can form areas of the support groove in which displacement of the coupling occurs due to the control bolt striking the edge defining it.

[0016] By strategically placing such designed support grooves on or within the couplings, it is possible that when the adjusting element begins to rotate, initially only one of the couplings shifts (the control bolt is in the straight section of its respective support groove), while the corresponding other coupling remains in its position (the control bolt is in the curved section of its respective support groove). With further rotation, the shift of the coupling that is now moving first ceases (the control bolt moves from the straight section of its respective support groove to its curved section), while the shift of the coupling that was not moving until this point begins (the control bolt moves from the curved section of its respective support groove to its straight section).

[0017] According to further possible designs of the support grooves in or on the couplings, the support grooves can be arranged such that the arcuate sections of the support grooves of the first coupling and the arcuate sections of the support grooves of the second coupling are curved in opposite directions relative to each other. Regarding the overlapping arrangement of the two couplings, the arcuate sections of their support grooves can be imagined to complement each other to form a common arcuate section, provided that the two couplings are stacked one on top of the other such that the ends of the two arcuate sections of their support grooves are aligned with each other.

[0018] In principle, this invention specifies that the coupling element capable of linear displacement with respect to the sliding direction can each have a guide groove extending parallel to the sliding direction. Thus, the rotating shaft has two shaft segments located on one side of the adjusting element, facing away from each other, the shaft segments pointing away from each other. Here, each shaft segment extends at least partially through the guide groove of its respective coupling element. It is possible in this way that the rotating shaft, with its shaft segments protruding relative to both sides of the adjusting element, extends through the guide grooves of both coupling elements. The extension direction of the guide groove enables displacement of the coupling element relative to the adjusting element in such a way that the two shaft segments of the rotating shaft of the adjusting element each pass through the guide groove of their respective coupling element.

[0019] Regarding this specification: the guide groove of each coupling element can intersect with its corresponding support groove. In other words, the guide groove and support groove of each coupling element can form a common pattern. Particularly preferably, the guide groove of the coupling element can intersect with its corresponding support groove in the transition area between the straight and curved sections of the support groove.

[0020] The adjusting element can serve as a pure support for the control bolt, allowing two coupling elements, which engage with the control bolt via their support slots, to be supported on the adjusting element solely by the control bolt. To ensure adequate support, particularly in possible end positions of the displaceable coupling elements and / or in positions where the control bolt is not intended for support in its respective support slot, at least one of the coupling elements can also be directly supported on the adjusting element. Therefore, the adjusting element can have at least one cam disk, or can be at least partially constructed as such a cam disk. Furthermore, at least one of the coupling elements can have a protrusion through which the associated coupling element can then be supported, in particular, on the outer edge of the cam disk in its corresponding position relative to the adjusting element.

[0021] The connection type specified by the locking device of the two coupling elements and the airflow adjustment assembly must be such that any possible displacement of the coupling element in operation, transverse to the longitudinal direction of the rotation axis of the adjustment element, can be compensated for without loss of functionality. Specifically for this reason, the shaft section of the rotation axis and the control pin can each have a length such that even if the coupling element shifts linearly about the sliding direction while a change in the spacing between the coupling elements occurs, the shaft section and the control pin also extend transversely to the sliding direction through their respective support and guide slots. If at least one of the coupling elements has a protrusion combined with the cam disk as described above, the protruding length of the coupling element can be chosen such that even if the spacing between the coupling elements changes, the coupling element can still be at least partially supported on the outer edge of the cam disk.

[0022] Advantageously, within the scope of this invention, is that each coupling element has at least one protrusion on its opposite edge, the protrusions being configured for hinged connection to a pivotable plate of its respective locking device. In this way, the coupling element provides the possibility of direct connection to the plate, such that the linear displaceability of the coupling element is directly translated into manipulation of the plate.

[0023] The control mechanism proposed according to the present invention enables a very compact yet robust construction of the control mechanism for the locking device of the airflow adjustment assembly. In particular, the intentionally short path for transmitting forces from the control system and existing wind loads ensures consistently accurate operation of the locking device under high loads.

[0024] Furthermore, the present invention also relates to an airflow adjustment assembly for a vehicle. The airflow adjustment assembly includes two locking devices coupled to a control mechanism according to the present invention.

[0025] The advantages thus obtained have been described in detail in relation to the control mechanism according to the invention, so as to avoid repeating the corresponding embodiments herein.

[0026] Preferably, the two locking devices can be arranged in a base frame that is, in particular, substantially rectangular. Each of the locking devices has at least one plate that is movably supported on the base frame at least via one of its two end segments.

[0027] Advantageously, the base frame has an intermediate connecting plate in which an actuator is fixed. Therefore, the driven element of the actuator can be connected to one of the two shaft segments of the rotating shaft of the adjusting element of the control mechanism in a torque-transmitting manner. For this purpose, the driven element and the shaft segment can have corresponding profiles, which can then be advantageously interlocked.

[0028] According to a preferred improvement of the airflow adjustment assembly of the present invention, the base frame of the airflow adjustment assembly can be divided by at least one wall element. Thus, the base frame can include a first through region having a first locking device and a second through region having a second locking device. For this purpose, the at least one wall element can extend between two opposing lateral profiles of the base frame. Alternatively, the division can be made via two wall elements, which can then extend respectively from one of the lateral profiles toward a mid-section of the base frame located between the two lateral profiles.

[0029] For particularly stable support of the adjusting element of the control mechanism, it is considered especially advantageous that the airflow adjusting assembly has a retainer suitable for this purpose. The retainer is constructed such that the section of the adjusting element's rotational axis connected to the actuator is supported on the corresponding driven element of the actuator, while the section of the adjusting element's rotational axis away from the actuator is rotatably supported on the retainer. In this way, the adjusting element is supported via two sections of its rotational axis, thereby achieving precise guidance of the adjusting element. For this purpose, the retainer may, for example, have three arms, which may be respectively fixed to one or two wall elements and the intermediate connecting piece of the base frame.

[0031] Figure 1 A perspective view of an airflow adjustment assembly 1 according to the invention is shown. The airflow adjustment assembly has a base frame 2, exemplarily designed herein as a rectangle, having two longitudinal profiles 3 and 4 spaced apart from each other and extending parallel to the longitudinal direction X. These longitudinal profiles are connected via two lateral profiles 5 and 6, also spaced apart from each other and extending parallel to the height direction Z. A median strip 7 of the base frame 2 is located between the two lateral profiles 5 and 6, extending parallel to the height direction Z between the two longitudinal profiles 3 and 4.

[0032] In the embodiment shown here, each of the two longitudinal profiles 3 and 4 is divided, purely illustratively, into two longitudinal profile segments 3a and 3b; 4a and 4b, which extend between one of the lateral profiles 5 and 6 and the intermediate connecting piece 7. Between each of the two longitudinal profile segments 3a and 3b; 4a and 4b, which are respectively opposed to each other on their longitudinal sides, is a wall element 8a and 8b, which extends parallel to the longitudinal direction X. The two wall elements 8a and 8b divide the base frame 2 into two through regions 9a and 9b; more precisely, into a first through region 9a and a second through region 9b. Here, in Figure 1The first through area 9a in the upper part is located in Figure 1 The first longitudinal profile 3 at the top is defined by two longitudinal profile sections 3a and 3b, two wall elements 8a and 8b, and corresponding portions of the two lateral profiles 5 and 6. In contrast, in... Figure 1 The second through region 9b, located below the first through region 9a, is formed by... Figure 1 The two longitudinal profile sections 4a and 4b of the second longitudinal profile 4 located at the bottom, the two wall elements 8a and 8b, and the corresponding portions of the two lateral profiles 5 and 6 are defined.

[0033] To allow the two through regions 9a and 9b to change their cross-sectional area with respect to their openings, a first locking device 10a is provided in the first through region 9a, and a second locking device 10b is provided in the second through region 9b. In the example shown here, each locking device 10a, 10b has four pieces 11 to 14, 15 to 18, which are movably supported on the lateral profiles 5 and 6 of the base frame 2 via their end sections away from the intermediate connecting piece 7. Conversely, the end sections of the pieces 11 to 14, 15 to 18 away from the lateral profiles 5 and 6 are movably supported on the intermediate connecting piece 7. Between the intermediate connecting piece 7 and the retaining member 19, which in the example shown here has a total of three arms 19a, 19b, 19c and is spaced apart from the intermediate connecting piece 7 in the lateral direction Y, there is an operating mechanism 20 according to the invention, which refers to... Figures 4 to 7 As described in detail elsewhere. The retainer 19 is fixed to the intermediate connecting piece 7 in the region of the first longitudinal profile 3 via its first arm 19a, while the other arms 19b, 19c are respectively connected to one of the two wall elements 8a, 8b.

[0034] Figure 2 Similarly shown Figure 1 A perspective view of the airflow adjustment assembly 1 from the other side. It can be seen that an actuator 21 is fixed on the intermediate connecting plate 7.

[0035] Figure 3 Again with Figure 1 The same illustration shows the airflow adjustment component 1. (Similar to...) Figure 1Unlike previous versions, the retainer 19 and the control mechanism 20 have been removed to allow free viewing of the design of the intermediate connecting piece 7. As can be seen, this intermediate connecting piece has a through opening 7a, which corresponds (shown as a dashed line) to the follower 21b of the actuator 21, shown in an exploded view away from the base frame 2. Furthermore, legs 22a, 22b are visible on the two wall elements 8a, 8b, configured to connect to the two arms 19b, 19c of the retainer 19. Another leg 22c is located at the upper end of the intermediate connecting piece 7 in the region of the first longitudinal profile 3, and this additional leg connects to the last arm 19a of the retainer 19.

[0036] Figure 4 and Figure 5 The construction of a control mechanism 20 according to the invention is shown, which is illustrated in an optional form. The control mechanism includes two coupling members 23, 24 that are at least partially overlapped at their cover sides, with an adjusting element 25 inserted between the coupling members. The adjusting element 25 has a rotational axis 26 extending parallel to the transverse direction Y, which is divided into two mutually spaced and oriented axis segments 26a, 26b. Figure 5 It can be concluded that the first shaft section 26a of the rotating shaft 26 has a profile corresponding to the profile of the follower 21a of the actuator 21 in a manner not shown in detail. To demonstrate the connection between the follower 21a and the first shaft section 26a of the rotating shaft 26, which allows torque to be transmitted via said profile, in Figure 4 The position of the actuator 21, which is normally fixed to the intermediate plate 7 of the base frame 2 (not shown here), is shown again. The second shaft section 26b of the rotation shaft 26, which is opposite to the first shaft section 26a and also opposite to the actuator 21, is constructed in a manner not shown in detail here for rotatable support in a corresponding receiving portion of the retainer 19 (not shown here) (see Figure 1 ).

[0037] For reference Figure 1 As already explained, the two coupling elements 23 and 24 are used to operate the two locking devices 10a and 10b. Specifically, the first coupling element 23 operates the first locking device 10a, while the second coupling element 24 operates the second locking device 10b. On the opposing edges 23a and 23b; 24a and 24b of each coupling element 23 and 24, two protrusions 27a and 27b; 27c and 27d; 28a and 28b; 28c and 28d are respectively provided, which are hinged to one of the plates 11 to 14 and 15 to 18 of the locking device 10a and 10b (see [link to documentation]). Figure 1 ).

[0038] Figure 6An exploded view of the control mechanism 20 according to the present invention is shown. This further illustrates the design of the two coupling elements 23, 24 and the adjusting element 25. (As with...) Figure 4 and Figure 5 As can be seen from the combined illustrations, the adjusting element 25 has a total of two control bolts 29 and 30. The first control bolt 29 is located on the side 25a of the adjusting element 25 facing the first coupling element 23, while the second control bolt 30 is located on the side 25b of the adjusting element 25 facing the second coupling element 24. Here, the control bolts 29 and 30 extend away from each other at the same distance from the longitudinal direction Y1 of the rotation axis 26 of the adjusting element 25, and the control bolts and the rotation axis 26 are in a common plane.

[0039] Furthermore, it can be seen that the adjusting element 25 is at least partially constructed as a cam disk. For this purpose, the adjusting element 25 has a curved outer edge R1 extending approximately 180° around the rotation axis 26. Opposite to this outer edge, the adjusting element 25 has a bulge 31 with a similarly curved outer edge R2. The two outer edges R1 and R2 are partially concave relative to each other. A total of four holes are currently provided in the adjusting element 25, particularly in the region of the outer edge R1, which, due to the absence of material there, contribute to the weight reduction of the adjusting element 25.

[0040] It also becomes clear from observing the two coupling elements 23 and 24 that each coupling element has a support groove 32 and 33 corresponding to the control bolts 29 and 30. In the complete state of the operating mechanism 20, each of the two control bolts 29 and 30 is at least partially engaged in the corresponding support groove 32 and 33 of the coupling element 23 or 24 (see in particular...). Figure 4 and Figure 5 The control bolts 29 and 30 and the support grooves 32 and 33 constitute the slide control device K, which converts the movement or rotation of the adjusting element 25 around the rotation axis 26 into a corresponding linear displacement of the two coupled elements 23 and 24 about the sliding direction Z1 parallel to the height direction Z.

[0041] The support groove 32 on the first coupling element 23 and the support groove 33 on the second coupling element 24 each have a straight section 32a, 33a and an arc section 32b, 33b connected thereto. As can be seen, the two arc sections 32b, 33b bend in opposite directions relative to each other. Furthermore, each coupling element 23, 24 has a guide groove 34, 35 extending parallel to the height direction Z or parallel to the sliding direction Z1. The support grooves 32, 33 and guide grooves 34, 35 of each coupling element 23, 24 are interconnected in such a way that the corresponding guide groove 34, 35 intersects with its corresponding support groove 32, 33. Specifically, the encounter between each guide groove 34, 35 and its corresponding support groove 32, 33 occurs in the transition region between its straight section 32a, 33a and its arc section 32b, 33b. In the complete state of the control mechanism 20, the shaft sections 26a, 26b of the rotation shaft 26 of the adjusting element 25 extend at least partially through the guide slots 34, 35 of the corresponding couplings 23, 24 (see in particular). Figure 4 and Figure 5 Furthermore, the two coupling elements 23 and 24 each have a protrusion 36 and 37, and the corresponding coupling elements 23 and 24 can be supported via the protrusion on the corresponding outer edges R1 and R2 of the adjustment element 25, which is configured as a cam disk.

[0042] Regarding the shaft sections 26a and 26b of the rotating shaft 26 and the control bolts 29 and 30 of the adjusting element 25 Figure 4 and Figure 5 The excess length shown in the diagram is chosen such that even if the spacing between the two coupling elements 23 and 24 changes while the coupling elements 23 and 24 are linearly displaced, the shaft section and the control bolt extend transversely to the sliding direction Z1 through their respective support grooves 32 and 33 and guide grooves 34 and 35 without the risk of slipping out.

[0043] Figure 7 A separate description of the adjusting element 25 is presented again in perspective view. Relative to... Figure 6 As shown in the diagram, the adjusting element 25 is rotated to observe its other side 25a, on which the first control bolt 29 is provided.

[0044] Figures 8a to 8e Explanation: The two locking devices 10a and 10b are operated asynchronously, at least partially, based on the rotational movement of the adjusting element 25 about its rotation axis 26. Figure 8a The following state is shown, in which both locking devices 10a and 10b are closed. The position of adjusting element 25 here corresponds to... Figure 7The adjusting element is oriented by twisting 180° about the longitudinal direction Y1 of the rotation axis 26. In other words, the outer edge R1 of the adjusting element 25 points upward about the height direction Z, while the edge R2 of the protrusion 31 points downward. (The rest of the text is incomplete and requires further context.) Figures 8b to 8e The states of locking devices 10a and 10b are shown respectively, which are obtained by rotating the adjusting element 25 by 45° respectively.

[0045] from Figure 8b It can be concluded that rotating the adjusting element 25 45° clockwise causes the first coupling member 23 to descend. This partially opens the first locking device 10a, while the second locking device 10b remains closed. In the described configuration, the first control bolt 29 is positioned within the straight section 32a of the support groove 32 of the first coupling member 23, such that the first coupling member is also at least partially displaced downwards (opposite to the height direction Z) by the downward movement of the first control bolt 29 about the rotation axis 26.

[0046] Figure 8c The first locking device 10a is shown now fully open, based on a total rotation of 90° made by the adjusting element 25. During this rotation, the first control bolt 29 is also within the straight section 32a of the support groove 32 of the first coupling member 23, causing the first coupling member to shift completely downward (opposite to the height direction Z).

[0047] During the rotation of the adjusting element 25 up to this point, the opposing second control bolt 30 passes through the arc section 33b of the support groove 33 of the second coupling member 24, so that the second locking device 10b does not produce any actuation displacement for the second coupling member 24.

[0048] from Figure 8d It can be concluded that the second locking device 10b begins to open, while the first locking device 10a remains fully open. The reason for this is that the adjusting element 25 rotates an additional 45°, thus the adjusting element now comes out of its initial position with a total twist of 135°. The second control bolt 30 is already... Figure 8c The second control bolt reaches the transition region between the arcuate section 33b and the straight section 33a of the support groove 33 of the second coupling member 24, so that the second control bolt reaches the straight section 33a during further rotation. At the same time, the opposing first control bolt 29 moves into the arcuate section 32b of the support groove 32 of the first coupling member 23, so that the first coupling member remains in its position, while the second coupling member 24 is further displaced downward (opposite to the height direction Z).

[0049] Figure 8eThe diagram shows the fully open state of the two locking devices 10a and 10b. In this state, the adjusting element 25 rotates a total of 180°, and the first control bolt 29 further passes through the arcuate section 32b of the support groove 32 of the first coupling member 23, while the second control bolt 30 further moves through the straight section 33a of the second coupling member 24. This causes the second coupling member to shift to its lowest position (opposite to the height direction Z), while the first coupling member 23 remains in its previous position.

[0050] By rotating the adjusting element 25 in the opposite direction, the previously described state proceeds in reverse order, so that the second locking device 10b can be locked first and then the first locking device 10a can be locked again.

[0051] Figure 9a and Figure 9a A cross-sectional view is shown of the operating mechanism 20 combined with the two locking devices 10a and 10b. Here, Figure 9a The following state is shown, in which both locking devices 10a and 10b are fully closed. As can be seen, in this position, the second coupling member 24 is supported on the edge R1 of the adjusting element 25 via its protrusion 37, while the protrusion 36 of the first coupling member 23 is spaced apart from the opposing edge R2 of the adjusting element 25. In contrast, Figure 9b The following state is shown in which both locking devices 10a and 10b are fully open. As can be seen, in this position, the first coupling element 23 is supported on the edge R2 of the adjusting element 25 via its protrusion 36, while the protrusion 37 of the second coupling element 24 is now spaced apart from the opposite edge R1 of the adjusting element 25. In the two extreme states of the locking devices 10a and 10b, one of the two coupling elements 23 and 24 is supported on one of the edges R1 and R2, which are configured as cam disks, via its respective protrusions 36 and 37.
