Description

[Technical Field]

[0001] The present invention relates to a gear stage selection device for selecting a gear stage in an automotive transmission, particularly in an automotive transmission having a shift-by-wire system. [Background technology]

[0002] In this case, the gear stage includes both the automatic gear stage, for example, "Drive" (D), "Neutral" (N), and "Reverse" (R), as well as the transmission shift stage, i.e., the transmission's set gear.

[0003] From Patent Document 1, the above-described type of gear stage selection device is known, which is configured to operate in both automatic operation mode and H-bridge operation mode. In automatic operation mode, known automatic gear stages (D, N, R, ...) can be adjusted by moving the selection lever forward and backward. In H-bridge operation mode, the gear shift stages, i.e., the gears of an automobile transmission, can be adjusted directly by moving the selection device forward and backward in combination with moving it left and right (similar to a conventional (mechanical) H-bridge).

[0004] In the sense of this application, the H-bridge operating mode also explicitly means an operating mode having four or more gear stages that are adjustable by forward / backward / left / rightward movement, and thus there are three or more side-by-side forward-backward shift tracks which can exit to the left and / or to the right in the center.

[0005] [Patent Document 1] German Patent Application Publication No. 102017114591 Specification [Overview of the project] [Problems that the invention aims to solve]

[0006] The present invention addresses the problem of implementing a gear stage selection device for selecting gear stages in an automotive transmission, which is configured to operate in both automatic and H-bridge operation modes and is relatively easy to construct. [Means for solving the problem]

[0007] This problem is solved according to the present invention by a gear stage selection device for selecting a gear stage of an automobile transmission having the features described in claim 1.

[0008] A gear stage selection device according to the present invention, for selecting the gear stage of an automotive transmission, is designed to be used in conjunction with or as part of a so-called shift-by-wire system, where there is no mechanical coupling between the gear stage selection device and the transmission mechanism; rather, electrical signals are transmitted between the gear stage selection device and actuators coupled to the transmission mechanism. The electrical signals are preferably transmitted via a vehicle bus, for example, via a so-called CAN-BUS and / or via a so-called FIBEX standard, or via an Ethernet connection. Typically, the gear stage selection device comprises its own control unit.

[0009] A gear stage selection device according to the present invention for selecting gear stages of an automotive transmission comprises a rotatably mounted shaft, which preferably has a circular cross-section. The shaft may be coupled to a rotary spring, thrust washer, stepper motor, or another type of actuator to generate a defined resistance when the shaft rotates.

[0010] A gear stage selection device according to the present invention for selecting a gear stage of an automotive transmission further comprises a slider device that is displaceable axially, i.e., parallel to the axial direction of the shaft. The slider device may comprise a slider element positioned on the shaft so as to be displaceable axially with respect to the shaft, or the shaft itself may be displaceable axially and form or be composed of the slider device.

[0011] A gear stage selection device according to the present invention for selecting a gear stage of an automobile transmission further comprises a selection lever coupled to a shaft and a slider device, wherein the shaft rotates axially when the selection lever is moved forward or backward, and the slider device is displaced axially when the selection lever is moved left or right.

[0012] A gear stage selection device according to the present invention for selecting a gear stage of an automotive transmission further comprises a rotation angle sensor for detecting the rotation angle of a shaft. The rotation angle sensor may be configured to directly detect the current rotation angle of the shaft by preferred detection means, or to detect the current rotation angle or current position of a component coupled to the shaft by preferred detection means. The rotation angle sensor may be configured to output an electrical output signal to a control unit of the gear stage selection device, for example, indicating the current rotation angle of the shaft or from which the current rotation angle of the shaft can be derived.

[0013] A gear stage selection device according to the present invention for selecting a gear stage of an automotive transmission further comprises a position sensor for detecting the axial position of a slider device.

[0014] The position sensor may be configured to directly detect the current axial position of the slider device by preferred detection means, or to detect the current location or position of components coupled to the slider device by preferred detection means. For example, the position sensor may be configured to detect by preferred detection means that detect a plurality of locking positions defined by a locking device to which the slider device is locked. For example, the position sensor may also be configured to detect the position of a guide element that is translationally coupled to the slider device within a guide link by preferred detection means. The position sensor may be configured to output an electrical output signal to, for example, a control unit of a gear stage selection device, indicating the current position of the slider device or from which the current position of the slider device can be derived.

[0015] A gear stage selection device according to the present invention for selecting a gear stage of an automotive transmission further comprises a cutoff device through which the axial displacement of the slider device, and therefore the leftward and rightward movement of the selection lever, can be selectively mechanically cut off and released. Rotation of the shaft, or forward and reverse movement of the selection lever, is not cut off by the cutoff device. With the cutoff device, as a result by cutting / releasing the slider device, shifts can be easily performed between automatic operating modes having a single forward-reverse shift track, and known automatic gear stages (D, N, R, ...) can be selected by forward or reverse movement of the selection lever, and an H-bridge operating mode has multiple side-by-side forward-reverse shift tracks, and gear stages representing individual gears of the vehicle transmission can be selected by forward and reverse movement, as well as leftward and rightward movement, of the selection lever.

[0016] Therefore, the combination of shaft, slider device, selection lever, and cutoff device according to the present invention enables the implementation of a simply constructed gear stage selection device for selecting gear stages of an automotive transmission, configured to operate in both automatic operation mode and H-bridge operation mode.

[0017] In a preferred embodiment of the gear stage selection device according to the present invention, the slider device is a slider element arranged on the shaft so as to be axially displaceable relative to the shaft, and is connected to the shaft in a torque-resistant manner via, for example, keying or another type of tangential positive locking. The slider device includes a slider element and a selection lever hinged to the slider element. When the selection lever moves forward or moves in reverse, the slider element and the shaft connected to the slider element in a torque-free manner rotate axially. When the selection lever moves left or right, the slider element is axially displaced relative to the shaft. This enables the implementation of a relatively compact gear stage selection device. Preferably, the slider element is mounted on the shaft, that is, held by the shaft in a displaceable manner. However, it is also generally contemplated that the slider element is held by a separate guide formed, for example, by a housing.

[0018] Preferably, the slider element is composed of one part.

[0019] In an alternative embodiment of the gear stage selection device according to the present invention, the shaft is configured to be axially displaceable, the slider device includes or is formed by an axially displaceable shaft, the selection lever is hinged to the shaft, and when the selection lever moves forward or moves in reverse, the shaft twists, and when the selection lever moves left or right, the shaft is axially displaced. This enables the implementation of a gear stage selection device consisting of relatively few separate parts because no separate slider element is required.

[0020] Preferably, the gear stage selection device according to the present invention comprises a locking device for locking the slider device in at least one locking position. Preferably, the locking device is configured to lock the slider device in a plurality of different locking positions. Preferably, the locking device is configured such that the locking is released on its own when the selection lever is pushed to the left or right with some force. Thus, preferably, the locking device is not intended to permanently fix the slider device in a locking position, but rather to generate significant resistance to displacement of the slider device outside of the locking position.

[0021] Preferably, the locking device comprises at least one receptacle disposed on the shell surface of the shaft and an engaging element radially biased relative to the shaft, the engaging element being configured to engage within at least one receptacle to lock the slider device in a locked position. Preferably, the locking device comprises a plurality of receptacles disposed at different axial positions on the shaft to define a plurality of locked positions. Preferably, the engaging element is a ball forced relative to the shaft by a spring element. In the simplest example, the at least one receptacle is formed by at least one recess configured on the shell surface of the shaft. However, the at least one receptacle may also be formed by at least one separate receptacle element disposed on the shaft.

[0022] At least one receptacle is preferably configured as a groove extending circumferentially along the shaft to allow for as unobstructed torsion as possible of the shaft when the slider device is in the locked position.

[0023] Generally, the shut-off device can be configured in any preferred manner to selectively shut off or release the axial displacement of the slider device. However, in a preferred embodiment of the gear stage selection device according to the present invention, at least one receptacle of the locking device is formed by at least one radially displaceable receptacle element on the shaft, and the shut-off device comprises a shut-off mechanism that can push at least one receptacle element against an engaging element to shut off the locking device and thus shut off the axial displacement of the slider device.

[0024] The pressure of at least one receptacle element against the engaging element can be released again in order to release the locking device and, therefore, to release the axial displacement of the slider device.

[0025] In a preferred embodiment, the blocking mechanism comprises an eccentric shaft rotatably disposed within the shaft, and by twisting the eccentric shaft, the radially inner side of at least one receptacle element abuts against it in a manner that allows at least one receptable element to be easily moved radially, thereby releasing the selective pressing of the receptacle element against the engaging element in order to block the locking device, and thus block the axial displacement of the slider device, or to release the locking device, and thus release the axial displacement of the slider device.

[0026] In an alternative, preferred embodiment, the blocking mechanism comprises an axially displaceable push rod having at least one flank, typically several flanks corresponding to the number of receptacle elements, with respect to the radially inward side of at least one receptacle element.

[0027] In this design, at least one receptacle element may be easily moved radially by the axial displacement of the push rod to release the pressure of the receptacle element against the engaging element in order to disconnect the locking device, and thus to disconnect the axial displacement of the slider device, or to selectively push the receptacle element against the engaging element in order to release the locking device, and thus to release the axial displacement of the slider device.

[0028] In an alternative, preferred embodiment, the shut-off device may also comprise a guide link and a guide element, for example, a pin-shaped guide element forcibly guided within the guide link, the guide link being translationally coupled to the slider device, for example, via a coupling rod or coupling bar, but preferably not rotationally coupled. The guide link has at least one shut-off position in which axial movement of the guide element through the guide link or through the opposing guide surface of the guide link is shut off, at the shut-off position of the guide link, so that the axial displacement of the slider device is shut off via the shut-off device. The guide link further has at least one release position in which axial movement of the guide element through the guide link is released, i.e., the guide element can move axially within the guide link, and at the shut-off position of the guide link, the axial displacement of the slider device is released via the shut-off device. The guide link is configured and arranged such that at least one shut-off position and at least one release position can be adjusted by moving the guide link relative to the guide element, for example, by sliding and / or twisting the guide link relative to the guide element. In its simplest form, the guide link may be T-shaped, for example, with one of the two branches of the T-shaped guide link positioned parallel to the axial direction of the shaft, and the other positioned laterally relative to the axial direction of the shaft. When the guide element is located within the branch extending laterally relative to the axial direction of the shaft, the axial movement of the guide element is blocked. When the guide element is located at the intersection of the two branches, the guide element can then be displaced in both axial directions within the branch extending parallel to the axial direction of the shaft. As a result, the blocked position (guide element within the lateral branch) or the released position (guide element at the intersection of the two branches) can be adjusted by moving the guide link laterally relative to the axial direction of the shaft. This allows for the implementation of a relatively simple and robust blocking device.A suitable configuration and movement of the guide links can provide multiple different operating modes, in particular a conventional (mechanical) H-bridge-like H-bridge operating mode, in a simple manner, and how the guide links are specifically configured and moved to implement a desired shift pattern, i.e., a desired movement pattern relative to the selection lever, will be obvious to those skilled in the art.

[0029] In a preferred embodiment, the guide link is formed by a push element that is displaceable relative to the guide element, allowing for simple adjustment of at least one closed position and at least one released position by displacing the guide link. This enables the implementation of a relatively simple and robust shutoff device. The push element is configured to be displaceable at least laterally with respect to the axial direction of the shaft, but may also be displaceable parallel to the axial direction of the shaft to implement more complex shift patterns or operating concepts.

[0030] In an alternative, preferred embodiment, the guide link is formed by a rotatable roller element such that at least one closed position and at least one released position can be adjusted in a simple manner by twisting the guide link. This allows for a relatively simple and robust implementation of the shut-off device. Preferably, the roller element is arranged coaxially with the shaft, i.e., the axis of rotation of the roller element preferably corresponds to the axis of rotation of the shaft. The roller element does not necessarily have to surround the shaft, but rather may be arranged axially adjacent to the shaft.

[0031] Roller elements do not necessarily have to have a circular or annular cross-section, but may have, for example, a circular segmented or annular segmented cross-section. For example, a roller element may be configured similarly to a shift cylinder used in a motorcycle to sequentially shift the transmission. To implement more complex shift patterns or operating concepts, it is also intended that the roller element be further displaceable.

[0032] Preferably, the guide link has a first release position in which the movement of the guide element is released in both axial directions, and at least one further release position in which the movement of the guide element is released in only one of the two axial directions. The first release position serves to implement an H-bridge operation mode in which the selection lever moves left and right to select a gear stage, starting from a central neutral position. The further release position is used to release a single additional shift track, for example, to implement a continuous shift operation mode in which gear stages indicating individual gears can be operated continuously by moving the selection lever forward and backward.

[0033] In principle, the guide link can be moved purely mechanically in any desired manner, for example, via a correspondingly configured manual actuation mechanism. However, preferably, the shutoff device is equipped with an actuator, preferably an electric motor, for the automatic movement of the guide link, and as a result, the movement of the guide link can be controlled by a correspondingly designed control unit. This allows for the implementation of particularly complex operating modes, for example, by automatically setting the shutoff position after leftward or rightward movement of the selection lever by the actuator. Furthermore, by moving the guide link by the actuator, it is intended that the guide element, and therefore the selection lever, may also be moved automatically, for example, by mimicking the shift force and stop of a mechanical H-bridge, and / or by feedback of the physical characteristics of an installed automatic or dual-clutch transmission, in order to automatically move the selection lever to the neutral position or a defined gear selection position in an H-shift operating mode, and / or to generate a shift feel as authentically as possible as part of a force feedback system.

[0034] In a preferred embodiment, the gear stage selection device according to the present invention comprises an electric motor, such as a so-called servo motor or actuator motor / stepper motor, the drive motor rotor of which is directly or rotationally coupled to the shaft by the transmission so that the shaft can receive torque from the electric motor, and the torque can generally be both a drive torque that drives the shaft and a braking torque that decelerates the shaft. This enables automatic movement of the shaft, and therefore the selector lever, for example, to automatically move the selector lever to the neutral position or the gear selection position. Furthermore, it is also intended that the electric motor be used as part of a force feedback system to generate the most authentic shift feel possible by intentionally driving and braking the shaft. In principle, it is also intended that different types of electromechanical actuators, such as magnetic / eddy current generating actuators or magnetorheological actuators, may be used to apply torque to the shaft instead of the electric motor.

[0035] Preferably, the electric motor includes a rotation angle sensor, or a position sensor for detecting the rotation angle or the position of the motor. Since the motor rotor is rotatably coupled to the shaft, the rotation angle of the motor rotor can also be used to directly derive the rotation angle of the shaft, so that the rotation angle sensor, or the position sensor of the electric motor, can be used as the rotation angle sensor of the gear stage selection device. In a preferred embodiment, the rotation angle sensor of the gear stage selection device is consequently integrated into the electric motor.

[0036] Preferably, the gear stage selection device according to the present invention comprises a spring assembly in which a slider device is configured to move in both axial directions against the spring force of a spring element, so that the slider device and thus the selection lever are biased to a central neutral position by the spring assembly. Preferably, the spring assembly comprises at least two spring elements arranged on opposing axial sides of the slider device. Similar effects can also be achieved by a suitably configured catch or flow contour.

[0037] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. The following are shown in the figures. [Brief explanation of the drawing]

[Figure 6] Figure 5 shows a schematic diagram of an alternative circuit breaker mechanism for the circuit breaker. [Modes for carrying out the invention]

[0039] Figure 1 shows a gear stage selection device 100 according to the present invention for selecting the gear stage of an automobile transmission.

[0040] The gear stage selection device 100 comprises a rotatable shaft 1 having a plurality of receptacles 1.1, each formed by a recess configured on the shell surface 1.2 of the shaft 1.

[0041] The gear stage selection device 100 further comprises a slider device 2 positioned on the shaft 1 in such a manner that it is displaceable in the axial direction relative to the shaft 1.

[0042] The slider device 2 comprises an annular slider element 2.1, which is held on the shaft 1 in such a manner that it surrounds the shaft 1 and is axially displaceable along the shaft 1.

[0043] The slider element 2.1 is coupled to the shaft 1 in a torque-resistant manner via keying formed on the inner circumferential surface of the slider element 2.1, or via another type of tangential positive locking.

[0044] The slider device 2 includes an engaging element 2.3 configured as a ball, which is positioned in a manner that allows for radial displacement in the recessed portion 2.1.1 of the slider element 2.1 and is biased against the shaft 1 via a spring element 2.4.

[0045] The engaging element 2.3 and receptacle 1.1 positioned on the shaft 1 form a locking device 3 for locking the slider device 2 at a plurality of locking positions defined by the receptacle 1.1 positioned on the shaft 1, and the engaging element 2.3 is configured to engage with one of the receptacles 1.1 positioned on the shaft 1 at the locking position, as shown in Figure 2.

[0046] The gear stage selection device 100 further comprises a selection lever 4 hinged to a slider element 2.1, and in the case of forward movement of the selection lever 4, i.e., movement of the selection lever 4 in the forward direction V, or in the case of reverse movement of the selection lever 4, i.e., movement of the selection lever 4 in the reverse direction R, the slider element 2.1 and consequently the shaft 1 also twist, and in the case of leftward movement of the selection lever 4, i.e., movement of the selection lever 4 to the left Li, or in the case of rightward movement of the selection lever 4, i.e., movement of the selection lever 4 to the right Re, the slider device 2 is displaced axially with respect to the shaft 1.

[0047] The gear stage selection device 100 further comprises an electric motor 5 located at the end of the shaft 1, the drive motor rotor 5.1 being connected to the shaft 1 in a torque-resistant manner.

[0048] The electric motor 5 includes a rotation angle sensor 5.2 configured to detect the current rotation angle of the motor rotor 5.1, and therefore the current rotation angle of the shaft 1 coupled to the motor rotor 5.1 in a torque-resistant manner.

[0049] The gear stage selection device 100 further comprises a position sensor 6 configured to detect the current axial position of the slider device 2.

[0050] The gear stage selection device 100 further comprises a shut-off device 7, through which the axial displacement of the slider device 2 can be selectively and mechanically shut off and released.

[0051] The shut-off device 7 includes a guide link element 7.1 which is composed of either a push element that can be displaced laterally relative to the shaft 1, or a rotatable roller element that is arranged coaxially with respect to the shaft 1.

[0052] The guide link element 7.1 is translationally coupled to the slider element 2.1 of the slider device 2 by a coupling rod 7.3, but is not coupled in the rotational direction. It forms a guide link 7.2, which forces a pin-shaped guide element 7.4 to be guided.

[0053] The guide link 7.2 has a closed position 7.5, a first open position 7.6, a second open position 7.7, and a third open position 7.8, which are shown in Figure 1, depending on the respective positions of the guide element 7.4 within the guide link 7.2.

[0054] At the blocking position 7.5, the axial movement of the guide element 7.4 is blocked, that is, the movement of the guide element 7.4 in the first axial direction A1 and the second axial direction A2 through the guide link 7.2.

[0055] In the first release position 7.6, the axial movement of the guide element 7.4 is released in both axial directions A1 and A2; in the second release position 7.7, the axial movement of the guide element 7.4 is released only in the first axial direction A1; and in the third release position 7.8, the axial movement of the guide element 7.4 is released only in the second axial direction A2.

[0056] The shut-off position 7.5 and the three release positions 7.6-7.8 may be adjusted by the movement of the guide link element 7.1 and therefore the guide link 7.2, where the guide link element 7.1, configured as a push element, is displaced laterally relative to the shaft 1 to adjust the shut-off position 7.5 and the three release positions 7.6-7.8, and the guide link element 7.1, configured as a roller element, is twisted relative to the shaft 1 to adjust the shut-off position 7.5 and the three release positions 7.6-7.8.

[0057] The shutoff device 7 further comprises an actuator 7.9 for the automatic movement of the guide link element 7.1, and therefore the guide link 7.2.

[0058] The gear stage selection device 100 further comprises a spring assembly 8 having a first spring element 8.1 positioned between the slider device 2 and the electric motor 5, and a second spring element 8.2 positioned between the slider device 2 and the guide link element 7.1.

[0059] As a result, the slider device 2 moves in a first axial direction A1 that counteracts the spring force of the first spring element 8.1, and in a second axial direction A2 that counteracts the spring force of the second spring element 8.2.

[0060] Figure 3 shows an alternative gear stage selection device 100 according to the present invention for selecting the gear stage of an automobile transmission. * Features identical or similarly known from the gear stage selection device 100 are shown, and corresponding reference numbers from Figures 1 and 2 are used.

[0061] Gear Stage Selection Device 100 * The shaft 1 is configured to be axially displaceable, and the slider device 2 is substantially formed by the axially displaceable shaft 1, and as a result, the axially displaceable slider element 2.1 is the gear stage selection device 100 * It is essentially different from the gear stage selection device 100 in that it does not exist internally.

[0062] Gear Stage Selection Device 100 * Inside, the position sensor 6 is configured to detect the current axial position of the shaft 1, i.e., the slider device 2, and the guide element 7.4, which is forcibly guided within the guide link 7.2, is coupled to the shaft 1 translationally but not rotationally.

[0063] Furthermore, gear stage selection device 100 * The spring assembly is configured such that the slider device 2, formed by the shaft 1, moves in a first axial direction A1 to counteract the spring force of the first spring element and in a second axial direction A2 to counteract the spring force of the second spring element (not shown).

[0064] Furthermore, in the gear stage selection device 100 * the locking device 3 comprises a fixed part 3.1 having a recess 3.1.1, in which an engaging element 3.2 configured as a ball is displaceable radially so that the engaging element 3.2 engages in one of each of the receptacles 1.1 arranged on the shaft 1 in the locking position, and is arranged to be biased against the shaft 1 via a spring element 3.3.

[0065] FIG. 4 shows the gear stage selection device 100, or an alternative guide link element 7.1 * for the gear stage selection device 100, * Features that are identical or similarly known from the guide link element 7.1 are denoted by corresponding reference numerals from FIGS. 1 to 3.

[0066] The guide link 7.2 of the guide link element 7.1 * has a central blocking position 7.10, a first lateral blocking position 7.11, and a second lateral blocking position 7.12, and a guide element 7.4 is forcedly guided within the guide link 7.2, so that the slider device is blocked by the three blocking positions 7.10, 7.11, 7.12 at different axial positions.

[0067] The three blocking positions 7.10, 7.11, 7.12 are connected to each other by a guide link section 7.13 extending diagonally, enabling the guide element 4, and thus the slider device 2, to move reliably in an axial manner by the movement of the guide link element 7.1 * in an axial manner.

[0068] The guide link 7.2 of the guide link element 7.1 * further comprises a first release position 7.14 and a second release position 7.15 in which the axial movement of the guide element 7.4 is released in both axial directions A1, A2.

[0069] FIG. 5 shows the gear stage selection device 100, or the gear stage selection device 100* Alternative circuit breaker 7 * The figures are illustrated, and features identical or similarly known from the circuit breaker 7 are indicated using the corresponding reference numbers from Figures 1 to 4.

[0070] Circuit breaker 7 * Unlike the interrupting device 7, the interrupting device 7.16 has, in effect, an interrupting mechanism 7.16 for interrupting the locking device 3 instead of the guide link 7.2 and guide element 7.4, as shown in Figure 2, and the gear stage selection device 100 as shown in Figure 3. * It can be used with both locking devices 3, and for that reason, reference numbers for both designs of locking device 3 are provided below and in Figure 5 for the features of locking device 3.

[0071] The locking device 3 comprises a plurality of receptacle elements 3.4 arranged within the shaft 1 in a manner that allows for radial displacement, each having a recessed portion 3.4.1 on its radially outward side that forms a receptacle 3.5 of the locking device 3.

[0072] The blocking mechanism 7.16 comprises an eccentric shaft 7.16.1 rotatably disposed within the shaft 1, and the radially inner side of the receptacle element 3.4 abuts against it, and by twisting the eccentric shaft 7.16.1, the corresponding receptacle element 3.4 may be selectively pressed against the engaging elements 2.3;3.2 to block the locking device 3 and thus block the axial displacement of the slider device 2, or the pressure of the receptacle 3.4 against the engaging elements 2.3;3.2 may be released to release the locking device 3 and thus release the axial displacement of the slider device 2.

[0073] Figure 6 shows the circuit breaker 7 * Alternative interruption mechanism 7.16 * Features that are identical or similarly known from the tripping mechanism 7.16 are shown, and the corresponding reference numbers in Figure 5 are used.

[0074] Shut-off mechanism 7.16 * It differs from the shut-off mechanism 7.16 in that, instead of an eccentric shaft 7.16.1, there is an axially displaceable push rod 7.16.2 having several flanks 7.16.3 corresponding to the number of receptacle elements 3.4, and the radially inward side of one of the receptacle elements 3.4 abuts against each of the flanks 7.16.3.

[0075] As a result of the axial sliding of the push rod 7.16.2, the corresponding receptacle element 3.4 may be selectively pressed against the engaging elements 2.3;3.2 to block the locking device 3 and thus block the axial displacement of the slider device 2, or the pressing of the receptacle element 3.4 against the engaging elements 2.3;3.2 may be released to release the locking device 3 and thus release the axial displacement of the slider device 2.
