Description

Technical Field

[0001] The present invention relates to a switch adjustment device, which includes a drive assembly with an actuating member, which acts together with a slider supported movably in an adjustment direction to move the slider along the adjustment direction. The switch adjustment device also includes an adjustment rod supported movably between a first adjustment position and a second adjustment position in the adjustment direction, and the slider is preferably connected to the adjustment rod in a driving manner in the adjustment direction via a drive-in coupling (Auffahrkupplung). The switch adjustment device also includes two detection slides (Prüferschieber) extending parallel to the adjustment rod and supported movably between a first adjustment position and a second adjustment position in the adjustment direction, and a locking slide that is displaceable transversely to the adjustment direction. Background Art

[0002] Switch adjustment devices of this type are described in DE 19525012 A1 and DE 202018101643 U1.

[0003] As is known, adjustment devices for movable switch parts, such as tongue-shaped rails or movable frogs, which are provided with integrated end position detection devices belong to the prior art. In the known adjustment devices, the mechanical switching of the switch parts is carried out by means of an electromechanical or hydraulic drive assembly, which drives an adjustment rod, wherein a locking device integrated in the switch drive is provided for locking the end position of the adjustment rod and the end position detection device. This end position detection device is used to mechanically detect the current state of the switch when switching the switch and to generate a detection signal, based on which it can be reliably determined whether the switch has been correctly switched and whether the near and far tongue-shaped rails are in their respective correct end positions. The end position detection device has two detection slides, which extend essentially transversely to the longitudinal direction of the track and move in the longitudinal direction of the corresponding detection slide when switching the switch. The position of the detection slide is detected by means of an electromechanical converter (for example in the form of a limit switch or tongue-shaped detection contact), which can be integrated into the adjustment device.

[0004] The integrated locking device of the electromechanical adjusting device according to DE 19525012 A1 comprises two locking slides, which can be displaced transversely to the displacement direction of the adjusting rod and in the corresponding locking position respectively engage in a locking recess of the adjusting rod in a form-fitting manner. Here, the first locking slide is provided for locking the adjusting rod in one end position, and the second locking slide is provided for locking the adjusting rod in the other end position. In the embodiment according to DE 19525012 A1, the locking slide is also designed so that the locking slide simultaneously engages in the corresponding locking recess of the detection slide in the locking position, so as to also lock the detection slide in the corresponding end position.

[0005] The locking slide is spring-loaded in the direction of the adjusting rod or the detection slide, so that the locking slide engages in the corresponding locking recess in a spring-loaded manner. Therefore, in order to unlock the corresponding end position, it is necessary to pull the corresponding locking slide back from the locking recess. In the subject of DE 19525012A1, a so-called switching rod (Schaltlineal) is provided for this purpose, which overcomes the spring force acting on the locking slide to move the locking slide due to the inclined surface of the switching rod contacting the roller arranged at the locking slide during the conversion process. Here, the switching rod is driven by the actuator of the drive assembly in the conversion direction, and the actuator causes the actual conversion of the adjusting rod only after passing the idle stroke. However, during the passage of the idle stroke, the switching rod has been driven in the conversion direction to cause the unlocking of the locking device described above. After passing the idle stroke, the actuator drives the slider connected to the adjusting rod in the adjustment direction in a driving manner in the conversion direction. This motion sequence ensures that the adjusting rod and the detection slide are unlocked before the conversion movement of the adjusting rod or the tongue-shaped track begins.

[0006] In order to achieve the turnout drive-in, the slide can be connected to the adjusting rod via a drive-in coupling. During normal switching operation, the drive-in coupling ensures that the adjustment movement provided by the slide is transmitted to the adjusting rod. Conversely, in the locked state of the adjustment device, when the turnout is driven in, such a large force acts on the adjusting rod that the drive-in coupling yields and the adjusting rod is moved to the other end position relative to the slide. In order to ensure that the adjusting rod and the detection slide are unlocked when driving in, according to the design of DE 19525012 A1, when the adjustment rod is moved by driving in, the locking slide in the locked position is pressed out of the locking recess of the adjustment rod. This is facilitated by the inclined flanks of the locking slide sliding on the corresponding inclined mating surfaces of the locking recess.

[0007] The switch lever provided in the described prior art has several disadvantages. Due to the switch lever, the drive-in coupling can only be supported in the lateral area of ​​the slide, which results in an asymmetrical force introduction. In addition, the system around the drive-in coupling is complex and has an asymmetrical position. In addition, the switch lever must be supported in a complex manner. It is also disadvantageous that unlocking via the inclined ramp at the switch lever leads to poor force transmission and has a negative impact on the wear characteristics.

[0008] In addition, the described switch adjustment device can only be converted from the right installation position in the switch to the left installation position with high cost, or vice versa, because only the front side is constructed for being installed at the switch drive. In the electronic mechanical switch drive described in the prior art, such conversion is carried out at this point, that is, if the switch drive should be installed on the right side of the switch or the left side of the switch in a certain travel direction, the housing side of the adjustment rod or the possible detection slide bar is maintained to leave from the drive housing. For this purpose, the entire housing must be rotated 180 °, which causes the detection slide bar to be located on the wrong side of the adjustment rod. Therefore, the detection slide bar must be disassembled and installed again at a cost, wherein, according to the installation position, the detection slide bar needs to be installed on the left or right side along the guide track of the adjustment rod. Thus, the structural space of the two guide tracks used for the detection slide bar is also required. Subsequently, the locking slide bar must also be adapted to the changed detection slide bar or guide track. Furthermore, it is considered that the contact element of the end position detection device must also be adapted to the housing rotated by 180° in order to output a detection signal corresponding to the switch position.

[0009] Hydraulic switch drives with a front side that can be used on both sides to avoid a 180° rotation when changing the installation position are known from the prior art. Due to the difficulty of construction or the excessive space requirement, this principle has not yet been applied to electromechanical switch drives. Summary of the invention

[0010] The object of the present invention is therefore to overcome the above-mentioned disadvantages and to provide a switch adjustment device which is of simple and robust construction and allows a safe mode of operation. In addition, a preferably drivable switch adjustment device should be provided with the same or less installation space requirement, in which one front side of the housing or both front sides of the housing are suitable for placement in the direction of the switch, independently of whether the switch adjustment device is to be driven electrohydraulically or electromechanically.

[0011] In order to achieve this object, according to a first aspect of the present invention, in a switch adjustment device of the type mentioned at the beginning, it is basically arranged that the first locking slide can be moved in a force-loaded manner into a first locking position in a first adjustment position, in which the first locking slide engages in a first recess of the slider, and the second locking slide can be moved in a force-loaded manner into the first locking position in a second adjustment position, in which the second locking slide engages in a second recess of the slider, wherein two motion transmission elements, preferably tilting levers, are arranged on the slider, the motion transmission elements can be operated by an actuating member and convert at least a part of the movement of the actuating member into the movement of an operating element which can be displaced in the first recess or the second recess of the slider, the operating element being arranged between the first locking slide or the second locking slide and the adjusting rod in the locking position, and engaging in the first recess or the second recess of the adjusting rod in the first locking position of the first locking slide or the second locking slide.

[0012] Therefore, the present invention is based on the idea that the corresponding locking slide does not directly cooperate with the adjusting rod in the locking position, but cooperates with the adjusting rod in the case of an operating element that can be operated by a motion transmission element in the middle, and the operating element is preferably configured as a rotatably supported roller or roller at least in the contact area with the adjusting rod or the locking slide. Here, the locking effect of the locking slide is achieved by the locking slide engaging in the recess of the slider. The operating element is arranged to displace the corresponding locking slide from its locking position to the release position at the beginning of the conversion process, that is, disengage the recess of the slider. This is achieved by the motion transmission element being driven by the acting member of the drive assembly at the beginning of the conversion process, and the operating element pressing the locking slide open. Thus, the unlocking of the corresponding adjustment position (that is, the end position) can be achieved by simple means. Since each of the two end positions is provided with its own motion transmission element, especially a tilting lever, the corresponding unlocking mechanism can be realized separately in structure, wherein in particular, the mirror-symmetrical arrangement of the motion transmission element is advantageous. Furthermore, this makes it possible to arrange the drive-in coupling in the region between the motion transmission elements and thus in the center of the slide, so that an asymmetrical introduction of forces is avoided.

[0013] According to a preferred embodiment, the motion transmission elements are each designed as a tilting lever, which is pivotably mounted and whose first lever arm can be actuated by the actuator and whose second lever arm has a corresponding actuating element.

[0014] Compared to an embodiment with a switching lever, a further advantage of unlocking with the aid of a motion transmission element, in particular a tilting lever and an operating element that can be operated thereby, is that the unlocking mechanism can be arranged in a space-saving manner between the drive assembly and the bottom of the housing, thereby saving material, reducing manufacturing costs and eliminating the guide rod of the switching lever, since a small bushing is sufficient for guiding the tilting lever.

[0015] The structure according to the invention also makes the unlocking process insensitive to reverse stresses. Reverse stresses may be generated, for example, by a stuck foreign body or a bent switch tongue and cause a load on the structural elements involved in the locking of the corresponding end position. However, since the locking slide in the first locked position is not directly engaged with the adjusting rod, but with the slider, the reverse stress acting on the locking slide is limited to the extent that can be transmitted by the drive-in coupling or to the adjustment force of the switch drive. In order to unlock the locking slide, the spring force that loads the locking slide and the friction force generated by the clamping with the slider must first be overcome. The locking slide can be reliably unlocked by a motion transmission element, for example, by transmitting the adjustment force of the drive device to the inclined lever on the locking slide in a manner that is not weakened in principle via an operating element.

[0016] Advantageously, the locking of the slide according to the invention by means of a locking slide engaging in a corresponding recess of the slide is caused, if the locking slide is stopped in both adjustment directions, that is to say accommodated in the corresponding recess substantially without play, the position of the slide in the locked adjustment position is clearly determined by the position of the recess in the slide. Preferably, the at least partially conical geometry of the locking slide engaging in the recess can ensure a play-free locking of the slide, wherein the conical geometry comprises a cross-sectional variation of the locking slide, wherein the width of the cross section measured in the adjustment direction preferably decreases continuously toward the free end of the locking slide. This results in two major advantages: 1. Impacts on the tongue track are absorbed directly by the locking unit in order to protect the spindle including the drive unit from damage due to impacts. 2. The fixed reference position of the slide and the adjusting rod enables the earliest possible or accurate identification of operation-related deviations in the measurement results of the test air measurement. The determination of the actual test air depends to a certain extent on the repeatedly identical, clearly determined position of the slide connected to the adjusting rod. As a result, the clear position of the slide and the adjusting rod makes a safety-related contribution.

[0017] Furthermore, advantageously, the locking of the slide according to the invention by means of a locking slide engaging in a corresponding recess of the slide results in that the adjustment travel of the adjusting lever is clearly defined by the distance between the two recesses in the slide and can be easily identified. The adjustment travel can be varied by replacing the slide with the correspondingly spaced recesses and is, for example, 150 mm, 180 mm or 220 mm. Instead of replacing the slide as a whole, it is also possible to change the distance of the recesses by replacing only a part of the slide. Thus, the two recesses can be provided as components of the slide in the form of an insert which can be replaceably assembled with the slide.

[0018] In order to provide a second locking stage as a backup stage in addition to locking the adjusting rod, a preferred development of the invention provides that the first locking slide engages in a first recess of the detection slide in the first locking position and the second locking slide engages in a second recess of the detection slide in the first locking position, thereby also fixing the detection slide in the end position.

[0019] When entering the switch, it must be ensured that the detection slide is unlocked, wherein the unlocking here cannot be achieved by actively actuating the motion transmission element, in particular the tilting lever, but by pressing the actuating element out of the recess of the actuating rod due to the relative displacement of the adjusting rod relative to the slide. In this regard, a preferred embodiment provides that the actuating element and / or the recess of the adjusting rod are dimensioned so that the actuating element, due to the entry process (in which the actuating element has been pressed out of the first recess or the second recess of the adjusting rod due to the relative displacement of the adjusting rod relative to the locked slide), moves the first locking slide or the second locking slide into a second locking position, in which the first locking slide remains engaged with the first recess of the slide or the second locking slide remains engaged with the second recess of the slide, but the detection slide is released. The second locking position of the locking slide, which is located between the first locking position and the release position, has the advantage that the slide remains locked when entering the switch, and the entry process can therefore be detected in the second locking position.

[0020] In order to ensure that the corresponding end position is unlocked before the adjusting rod is moved during the conversion process, it is preferably provided that the actuating member cooperates with the corresponding stop part of the slide after the idle stroke to drive the slide in the corresponding adjustment direction, wherein the corresponding motion transmission element, in particular the first lever arm of the corresponding tilting lever, can be manipulated by the actuating member along the idle stroke.

[0021] In particular, it is provided that the actuating element of the second lever arm displaces the first or second locking slide at the end of the idle travel of the entrainment member into a release position out of engagement with the first or second recess of the slide.

[0022] In this respect, the first locking slide or the second locking slide is designed to be disengaged from the first recess or the second recess of the detection slide in the second locking position.

[0023] According to a preferred improvement, the first locking slide and the second locking slide are respectively provided with a first locking lug and a second locking lug, wherein the first locking lug is arranged to engage in the first recess or the second recess of the slider in the first locking position and the second locking position of the locking slide, and the second locking lug is arranged to engage in the first recess or the second recess of the detection slide in the first locking position.

[0024] As is known per se, the first locking slide and the second locking slide can interact with corresponding electrical switches which signal that the correct end position has been reached.

[0025] In order to achieve a compact structure, a preferred design provides that the first locking slide and the second locking slide are guided movably in a sliding manner transverse to the adjustment direction. In addition, the sliding arrangement achieves better absorption of locking forces acting on the locking slide transversely to the movement direction of the locking slide, that is, in the adjustment direction.

[0026] Particularly advantageously, the locking slide can be displaceably guided in a locking block which, on both outer sides, surrounds the locking slides sliding against one another in a form-fitting manner.

[0027] If the detection slide runs through the locking block as in another preferred embodiment of the present invention, its arrangement takes up less structural space in the housing. In addition, the locking block can radially surround the detection slide in order to fix the position of the detection slide relative to the locking slide, thereby ensuring a simple and at the same time stable position fixation.

[0028] In order to realize the simple conversion of the switch adjustment device according to the present invention from the right installation position to the left installation position and vice versa without replacing the components, it is preferably provided that the switch adjustment device also includes a housing, in which the drive assembly, the actuator, the slide, the drive-in coupling and the locking slide are arranged, and the adjustment rod and the detection slide respectively penetrate the housing opening of the housing at the opposite housing side and are movably supported in the housing opening. Here, depending on the installation position, the adjustment rod and the detection slide can either leave from one housing side or from the other housing side and be guided to the tongue-shaped track, wherein the remaining components (such as, in particular, the locking slide, the actuator, the slide and the drive-in coupling) do not need to be adapted. For this purpose, the central arrangement of the components and their symmetrical implementation are particularly advantageous.

[0029] In summary, the invention allows a modular design of a switch adjustment device, in which, for example, the drive assembly can be replaced as a module without having to dismantle or refit other components. Thus, a drive assembly with an electromechanical drive (e.g. an electric motor) or a drive assembly with an electrohydraulic drive (i.e. an electrically operated hydraulic cylinder-piston assembly) can be selectively installed.

[0030] In this regard, the use of motion transmission elements, such as tilting levers for the locking and unlocking mechanisms, which are located outside the module replacement path and thus also facilitate the modular design of the switch adjustment device, should be mentioned as a further advantage. Although the modules are joined to one another at certain locations, they are not stacked one on top of another, so that after loosening the screw connection with the housing, each module can be easily lifted upwards individually, for example in order to easily replace the module.

[0031] In order to further improve the suitability of one or both front sides of the switch drive for installation in the direction of the switch, independently of the drive type (hydraulic or mechanical), further aspects of the invention are provided below, which, compared with the solutions common in the prior art, on the one hand require fewer components and installation space and on the other hand cause less maintenance and wear. The further aspects are independent of the first aspect of the invention.

[0032] According to a second aspect of the present invention, a locking block for a switch adjustment device is provided, the locking block comprising two side walls and at least one locking slide movably guided between the side walls, the locking slide being used to lock at least one detection slide and an adjustment rod of the switch adjustment device, wherein the side walls respectively have a notch for guiding at least one detection slide to pass through the locking block in a direction extending transversely to the movement direction of at least one locking slide.

[0033] In a symmetrical design, in which only one guide rail is required for the detection slide, the guide rail for guiding the detection slide or the detection slide can extend through the locking block in order to further save construction space. For example, the wall or housing of the locking block surrounding the locking slide can have a hole, a notch or a recess in order to guide the detection slide through.

[0034] In addition, preferably, a vertical recess is provided in the locking slide extending between the walls of the locking block. Here, the vertical side of the vertical recess can be used to lock two detection slides extending through the vertical recess one above the other. Thus, the locking of the detection slide is carried out in the locking block.

[0035] Due to the central arrangement, the relative position between the test rod, the locking block and the locking slide is ensured even in the case of an unusually high tension of the switch adjustment device.

[0036] According to a third aspect of the present invention, a locking device for a switch adjustment device is provided, the locking device comprising a slider that can be driven by a drive assembly and is movably supported in an adjustment direction, the slider having a hole that passes through the slider for accommodating an adjustment rod, wherein at least one recess is constructed in the slider, and a locking slide can be pushed into the recess transversely to the adjustment direction to lock the slider, wherein the at least one recess leads to the hole.

[0037] This embodiment allows both the slide and the adjusting rod guided in the slide to be locked with a single locking slide, as already explained in conjunction with the first aspect of the invention. In particular, the adjusting rod can be contacted by the locking slide with an actuating element arranged in between, or the actuating element can spatially intersect the hole in the slide. In this case, the adjusting rod can preferably have a recess for engaging the actuating element.

[0038] In particular, when using an actuating element which is circular in cross section, in conjunction with a matching rounded recess in the adjusting lever, cutouts in the adjusting lever which are susceptible to stress concentrations can be avoided.

[0039] Since the actuating element is moved along during the adjusting movement at the height of the recess of the adjusting rod and the end position is locked via the larger recess in the slide, the recess of the adjusting rod can be significantly smaller and thus more gentle on the adjusting rod cross section.

[0040] A further advantage is that all the essential positions of the component are recorded centrally on one line and without branches, which saves space.

[0041] The locking device of the third aspect of the invention can be particularly advantageously combined with the locking block of the second aspect of the invention, that is, in such a way that the locking device and the locking block abut one another. This results in a saving of space and material and enables a multiple function of the component. In addition, this allows a particularly short design of the locking slide, which results in a saving of material.

[0042] For this purpose, it can be provided that the slide is arranged on the locking slide in a sliding manner in a release position of at least one locking slide, in which the slide is disengaged from a recess of the slide.

[0043] Preferably, the slide block can also be arranged in a sliding manner on the locking block, in particular on a side wall of the locking block.

[0044] According to a fourth aspect of the present invention, a switch adjustment device is provided, which includes a housing, in which are arranged: a locking device according to the third aspect of the present invention; a locking block according to the second aspect of the present invention; a drive assembly having an actuating member, which acts together with a slider movably supported in an adjustment direction to move the slider in the adjustment direction; and an adjustment rod movably supported between a first adjustment position and a second adjustment position in the adjustment direction, the slider preferably being connected to the adjustment rod in a driving manner in the adjustment direction via a drive-in connector.

[0045] This results in an advantageous arrangement of the individual modules of the switch adjustment device in the housing, namely a) the drive assembly, b) the adjusting rod with the slide and c) the locking block. The three modules are arranged adjacent to one another transversely to the adjustment direction, i.e. such that the adjusting rod with the slide is arranged between the drive assembly and the locking block. If the modules engage with one another but do not overlap, it is possible to install or remove individual modules independently of the other modules, so that the modules can be removed upwards from the housing independently of one another.

[0046] Preferably, the slide and the active element of the drive assembly are guided in a rolling manner in a groove in the housing bottom, which results in a space-saving guidance without sliding rods or the like.

[0047] Furthermore, a symmetrical-central arrangement of the modules between two housing walls lying opposite one another in the adjustment direction is advantageous, so that the switch adjustment device is suitable for use on both sides, that is to say for installation positions on the left or right. In addition, a change of the installation position can also be simplified by arranging a coupling for a hand crank of a possibly provided manual drive on the upper side of the housing. Here, the rotational movement of the hand crank can be guided to the drive shaft or transmission shaft of the adjustment drive by means of a flexible shaft in the interior of the housing.

[0059] exist Figure 1 1 shows a switch adjustment device, in which all components required for driving and transmitting adjustment movements, for locking end positions, for detecting end positions and for realizing switch entry are arranged in the housing 2 of the switch adjustment device. A drive assembly is provided, which comprises an electric motor 3 and a spindle transmission mechanism driven by the electric motor 3 with an intermediate transmission mechanism 4, which provides a linear adjustment movement in the direction of the axis of the spindle 5. For this purpose, an actuating member 6 equipped with a spindle nut cooperates with a slide 7 in a manner that will be described in detail below, so as to transmit the adjustment movement to the slide 7. The slide 7 is in turn connected to an adjustment rod 9 via a drive-in coupling 8, via which the adjustment movement corresponding to the double arrow 10 is transmitted to a tongue-shaped track not shown. Preferably, the slide 7 and the actuating member 6 are guided in a rolling manner in a groove in the bottom of the housing.

[0060] The hand crank 11 is part of a manual drive device, by which the drive assembly can be manually operated as required.

[0061] In order to check the correct occupation of the end positions, the detection slides 12 and 13 are connected to the tongue-shaped rails, and the detection slides are also movably supported in the housing 2 according to the double arrow. In addition, a first locking slide 14 and a second locking slide 15 are provided, which are guided movably between the release position and at least one locking position separately from each other transversely, in particular perpendicularly, to the longitudinal extension of the adjusting rod 9 and the detection slides 12, 13. In the locking position, the corresponding locking slides 14, 15 cause the adjusting rod 9 and the detection slides 12, 13 to be locked in the corresponding end position, as will be explained in detail in the following figures.

[0062] exist Figure 2 1 shows the switching device in the right end position. To lock this end position, the first locking slide 14, which is loaded by the force of the spring 17, is sunk with the locking lug into the first recess or slot 16a on the left side of the slide 7. The locking lug is elastically pressed against the roller 19a, which is sunk into the first recess 18a of the adjusting lever 9 (see Figure 7 and Figure 8 ). The roller 19a is arranged on the second lever arm 21a of the tilting lever 20a, which is fastened pivotably about the axis 22a on the slide 7. The first lever arm 23a is arranged to be actuated by the actuator 6. For locking the left end position, a mirror-image design of the described components is provided on the right side of the slide 7. Correspondingly, the tilting lever 20b is fastened pivotably about the axis 22b on the slide 7, wherein the first lever arm 23b is arranged to be actuated by the actuator 6 and the second lever arm 21b carries the roller 19b, which is held displaceably in the second recess 18b of the adjusting lever 9.

[0063] exist Figure 2 In the end position shown in FIG. 1 , the locking lugs of the first locking slide 14 also engage in the first recesses 25 and 26 of the first detection slide 12 or the second detection slide 13 in order to also check or lock the detection slides 12 , 13 in their end position.

[0064] exist Figure 2 and Figure 3 It can also be seen that the actuating member 6 acts on the slide 7 between the two stops 24a and 24b, wherein the actuating member 6 is dimensioned so that it only interacts with the opposite stop 24a or 24b after the idle travel x from the end position, so that the slide 7 is not driven in the switching direction until after the idle travel x. Figure 2In the end position shown in the figure, the actuator 6 is moved to the left by the drive assembly, wherein the actuator 6 actuates the first lever arm 23a of the tilting lever 20a when passing through the idle travel x, whereby the tilting lever 20a pivots about the axis 22a, and the roller 19a arranged at the second lever arm 21a escapes from the first recess 18a of the adjusting rod 9 and presses the first locking slide 14 out of the first recess 16a of the slide 7. At the same time, the detection slides 12 and 13 are also unlocked. In this way, the Figure 3 . The idle travel x is composed of a first partial travel and a second partial travel. Along the first partial travel, the tilting lever 20a is not yet driven. In the embodiment with an electromechanical drive, the distance until the tilting lever is actuated is greater than in the case of a hydraulic drive. The second partial travel is then used to actuate the tilting lever 20a.

[0065] Since the stop is at the stop portion 24a of the slide block 7, the action member 6 continues to move to the left, causing the slide block 7 together with the adjustment rod 9 connected to the slide block to be displaced, as shown in Figure 4 Here, the detection slide bars 12 and 13 are also driven in the conversion direction by the tongue-shaped track. After the entire conversion stroke, the Figure 5 , in which the second locking slide 15 can now enter the second recess or slot 16b of the slide 7 in a spring-loaded manner. Here, the second locking slide 15 presses the roller 19b arranged at the second lever arm 21b of the tilting lever 20b into the second recess 18b of the adjusting lever 7, so as to lock the adjusting lever 9 in the left end position, as in Figure 6 At the same time, the locking lugs of the second locking slide 15 engage in the second recesses 27 and 28 of the detection slide 12 or 13, so that the detection slide is also checked in its end position or locked in its end position.

[0066] exist Figures 2 to 6 It can also be seen that the first locking slide 14 and the second locking slide 15 are received in a positively locking manner in the locking block 29 and are guided there in the displacement direction.

[0067] In accordance with Figure 7 and Figure 8 The left end position is shown again in the cross-sectional view of Figure 7In addition, the structural details of the drive-in coupling 8 can be seen in the figure. The drive-in coupling 8 includes a pressure element 30, which is pressed against the adjusting rod 9 by a spring 31 with a ball or roller 32 connected in between, wherein the ball or roller 32 engages in a recess 33 of the adjusting rod 9 and thus ensures a force-fitting and form-fitting connection between the adjusting rod 9 and the slide 7. When the turnout is driven in, such a force is applied by the tongue-shaped rail to the adjusting rod 9 and by the adjusting rod to the locked slide 7, so that the ball or roller 32 together with the pressure element 30 is pressed upwards against the force of the spring 31, thereby causing a relative movement of the adjusting rod 9 with respect to the slide 7. This is shown in FIG. Fig. 9 and Fig.10 From Figure 8 and Fig.10 The comparison of shows that during the entry, the roller 19b is simultaneously pressed out of the second recess 18b of the adjusting lever 9, wherein the roller 19b itself pushes the second locking slide 15 back into the second recess 16b of the slide 7. However, the second locking slide 15 remains in the intermediate position (second locking position) in which the slide 7 remains locked. However, the displacement of the second locking slide 15 is sufficient for the locking lug associated with the detection slide 12, 13 to leave the second recess 27 or 28 of the detection slide 12, 13, so that the detection slide is released and the entry is detected.

[0068] Since the unlocking of the detection slides 12, 13 described above is not performed until after a certain switching stroke, the second recess 27 formed in the first detection slide 12 is formed larger in the longitudinal direction than the second recess 28 formed in the second detection slide 12. This takes into account the fact that the right-hand end position of the first detection slide 12 shown here, from which the switch is driven in, is associated with a far tongue-shaped track, which is displaced in time before the near tongue-shaped track during the driving-in process. The same applies to the first recesses 25 and 26 that act in the other end position, wherein here, in turn, the first recess 26 formed in the second detection slide 13 is formed longer than the first recess 25 formed in the first detection slide 12, because the second detection slide 13 is associated with the far tongue-shaped track.
