- Such a design is naturally mechanically resilient only to a small extent, in particular in the course of track maintenance work, such as Gleisstopfin, the directly associated with the movable rail or switch parts of the linkage is insufficiently protected.
- the DE 19623286 shows and describes an embodiment in which telescopically displaceable plates are provided relative to each other, which can be brought up to close to the rail of a stock rail, whereby at least an improved seal against in these areas Dust, ice od. Like. Is achieved. Since the lid construction provides a plurality of telescopically slidable plates and such plates can not be made arbitrarily thick to ensure undisturbed operation, the mechanical load capacity is naturally limited in such a configuration, wherein the plurality of gaps between adjacent sliding flat plates The risk of trituration and clamping of dirt, small rock and in particular the risk of icing can not be dismissed out of hand.
- the invention now aims to provide a cover of the type mentioned above, which ensures a high degree of reliability while the most complete coverage possible critical portions, such as the connection to movable switch or rail parts, while the mechanical strength is improved and avoids the risk of blockage due to the ingress of fine dust or icing.
- the training according to the invention aims to ensure safe protection of sensitive parts of the point-setting system, even in the case of rough loads caused by track-laying installations.
- the cover according to the invention essentially consists in providing a central tunnel-shaped lid open to the trough threshold with a substantially U-shaped cross-section, the axial length of which is dimensioned in the direction of the trough threshold such that a collision with displaceable switch parts, in particular tongues , Is avoided, and that with sliding switch parts in the direction of the same coupled cover caps are provided which engage the central tunnel-shaped cover over or under and are guided on this slidably.
- Such a construction is thus characterized by a particularly good protection of the sensitive connection points to the movable switch parts and also by a high degree of stability, the tunnel-like construction not only provides improved protection against mechanical influences but also against falling rock.
- condensation or rainwater can escape laterally at temperatures around freezing also reduces the risk of icing.
- the inventive construction is made in this case that the central tunnel-shaped lid is convex or polygonal in cross-section outwardly and is supported with two substantially normal to the trough threshold extending free legs on the trough threshold.
- Such a design increases the mechanical rigidity and stability.
- the central tunnel-shaped lid carries on its free legs outside guide profiles, which cross-over with corresponding inner guide profiles of the central tunnel-shaped lid cooperate side covers.
- the central tunnel-shaped lid may preferably be formed of metal, wherein it is quite sufficient if the lateral cover caps are made of impact-resistant plastic.
- the relatively short-built side caps must therefore be formed only from suitably impact-resistant plastic to ensure the necessary mechanical strength, at the same time the choice of a corresponding plastic significantly reduces the risk of icing.
- the training is such that the lateral caps wear transversely to the axis of the tunnel or the trough threshold elongated holes, such elongated having carriers or grooves, immersed in which connected to the movable rail parts coupling members or bolts, so as to ensure that at a pivoting of switch parts, such as tongue rails, a corresponding motion compensation relative to the caps, which are only moved straight, is guaranteed.
- the slots can in this case in the cap itself, in a cap connected to the support, which may be, for example, pivotally fixed to the cap, or only be formed as grooves, in which case the coupling members only engage in the grooves and not as in the case of slots can prevail.
- grooves allows immediate coverage beyond the area of the connection to the movable point or crossing parts and in particular the movable tongue rails addition.
- a further protection can be achieved by covering the oblong holes of parts of the lateral covering caps with the material of the covering caps.
- the points drive is usually set in or on trough sleepers, which also carry base plates and a corresponding slide chair.
- trough sleepers which also carry base plates and a corresponding slide chair.
- FIG. 2 is a side view in the direction of the arrow II of Figure 1 partially in section
- Figure 3 shows a section along the line III / III of FIG. 2 through the cover and the trough threshold, where for the sake of clarity turnout drive parts are not shown
- Figure 4 shows a detail of the connection of the side cover to a tongue rail
- Figure 5 shows a modified training in an analogous representation as Figure 4 and Figure 6 another modified design of the connection of the side covers on the point drive and the tongue rail of a switch.
- a multi-part cover which has a central to the trough threshold 1 open tunnel-shaped cover 2 with a substantially U-shaped cross-section.
- the tunnel-shaped cover 2 is encompassed by two lateral cover caps 3, these cover caps carry elongated holes 4, in which associated with tongue rails 5 and thus movable switch parts actuators are engaged.
- the elongated holes 4 allow a corresponding compensating movement of bolts or pins in an expansion and displacement of the tongue rails 5 in the direction of the double arrow 6 to corresponding jaw rails.
- the inner middle part of the tunnel-shaped cover 2 which is open downwards or to the trough sleeper 1, can be made of relatively thin-walled metal and ensures a high degree of mechanical stability through its cambered or roof-shaped structure.
- the side covers 3 embrace this middle open to the trough threshold tunnel-shaped cover 2 and there are the guides 8 can be seen, which cooperate with corresponding counter-profile in the side covers 3.
- the guide rails 8 are dimensioned in their length so that the lateral sliding covers can be inserted in a simple manner, the fixed middle part of the tunnel-shaped cover can be clamped on the trough threshold and secured in a simple manner, for example with a lock against disassembly can.
- the overall substantially trapezoidal cross section does not surmount the clearance space for the Stopfarme, which can be used with appropriate inclination even without collision with such a lid for use.
- FIG 4 the coupling of the point machine to the side cover 3, as it was already apparent in Figures 1 and 2, shown in detail.
- the drive linkage 13 carries a pin 10, which is connected to the tongue rail 5 directly via a schematically indicated with 15 coupling member.
- the cap 3 itself carries a pivotable plate 16 with the already shown in Figures 1 and 2 slot 4, so that after placing the cap 3 and pushing the cap 3 on the guides 8 of the central region by simply pivoting this plate-shaped member 16 of Pin 10 comes directly into engagement with the slot 4 and in the manner of its adjustment in the direction of the double arrow 9, the cap 3 moves accordingly.
- a flexible extension 17 connected to the covering cap 3 further covers the region of the coupling to the tongue rail 5 and in this way represents an extended protection.
- the upwardly facing pin 10 of the switch rod 13 engages in a groove 18 and thus causes the entrainment of the cap 3.
- the cap 3 carries a corresponding pin 19, which itself in turn connected to a slot of a plate-shaped intermediate member 14 which acts on the upwardly directed pin 10 of the point linkage 13 is connected.
- this is thus a kind of kinematic reversal, in which the slot 4 is housed in a part carried by pin 10 part.

Abstract
Description
Die Erfindung bezieht sich auf eine Abdeckung für in oder oberhalb einer Trogschwelle angeordnete Antriebs-, Verschluss- und/oder Prüfergestänge eines Weichenantriebs.The invention relates to a cover for arranged in or above a trough threshold drive, closure and / or Prüfergestänge a points drive.
Trogschwellen eignen sich in besonders guter Weise für den geschützten Einbau von Antriebs-, Verschluss- und/oder Prüfergestängen eines Weichenantriebs. Eine Abdeckung für derartige Teile eines Weichenantriebs ist beispielsweise der
Um empfindliche Teilbereiche des Gestänges und insbesondere Teilbereiche, in welchen derartige Gestänge gekröpft oder gewinkelt ausgeführt sind, besser zu schützen, ist es aus der
Die
Die Erfindung zielt nun darauf ab, eine Abdeckung der eingangs genannten Art zu schaffen, welche ein hohes Maß an Betriebssicherheit bei gleichzeitiger möglichst vollständiger Abdeckung kritischer Teilbereiche, wie beispielsweise des Anschlusses an bewegliche Weichen- oder Schienenteile, gewährleistet, wobei gleichzeitig die mechanische Belastbarkeit verbessert wird und die Gefahr einer Blockade durch Eindringen von Feinstaub oder durch Vereisung vermieden wird. Insbesondere zielt die erfindungsgemäße Ausbildung darauf ab, auch bei rauen Beanspruchungen durch Gleisstopfanlagen einen sicheren Schutz empfindlicher Teile des Weichenstellsystems zu gewährleisten. Zur Lösung dieser Aufgabe besteht die erfindungsgemäße Abdeckung im Wesentlichen darin, dass ein mittlerer zur Trogschwelle offener tunnelförmiger Deckel mit im Wesentlichen U-förmigem Querschnitt vorgesehen ist, dessen axiale Länge in Richtung der Trogschwelle so bemessen ist, dass eine Kollision mit verschiebbaren Weichenteilen, insbesondere Zungen, vermieden wird, und dass mit verschiebbaren Weichenteilen in Verschieberichtung derselben gekuppelte Abdeckkappen vorgesehen sind, welche den mittleren tunnelförmigen Deckel über- oder unter greifen und an diesem verschieblich geführt sind. Dadurch, dass ein mittlerer zur Trogfläche offener tunnelförmiger Deckel vorgesehen ist, wird zunächst aufgrund der Profilform bzw. der Tunnelbauweise ein hohes Maß an Stabilität sichergestellt, wobei der im wesentlichen U-förmige Querschnitt so ausgebildet werden kann, dass die Breite der Schwelle an keiner Stelle überschritten wird, um eine sichere Auflage des U-Profils auf der Trogschwelle zu gewährleisten und gleichzeitig sicherzustellen, dass Kollisionen mit Stopfarmen bei einem Nachstopfvorgang vermieden werden. Zusätzlich zu diesem mittleren, im Wesentlichen U-förmigen Querschnitt aufweisenden tunnelförmigen Deckel, dessen axiale Länge in Richtung der Trogschwelle naturgemäß so bemessen sein muss, dass eine Kollision mit den verschieblichen Weichenteilen mit Sicherheit ausgeschlossen werden kann, sind nun jeweils seitlich mit den verschiebbaren Weichenteilen jeweils in Verschieberichtung gekoppelte Abdeckkappen vorgesehen, deren axiale Länge entsprechend größer als der maximale Verstellweg der Weichenteile gewählt ist, um eine sichere Abstützung am mittleren tunnelförmigen Deckel zu gewährleisten, wobei die Ausbildung so getroffen ist, dass der mittlere tunnelförmige Deckel von den seitlichen Abdeckkappen übergriffen wird und die Abdeckkappen am mittleren Teil geführt sind. Eine derartige Konstruktion zeichnet sich somit durch einen besonders guten Schutz der empfindlichen Anschlussstellen an die beweglichen Weichenteile und auch durch ein hohes Maß an Stabilität aus, wobei die tunnelartige Konstruktion nicht nur einen verbesserten Schutz gegen mechanische Einflüsse sondern auch gegen herabfallendes Gestein darstellt. Dadurch, dass Tauwasser oder Regenwasser bei Temperaturen um den Gefrierpunkt seitlich abrinnen kann, wird auch die Gefahr einer Vereisung verringert.The invention now aims to provide a cover of the type mentioned above, which ensures a high degree of reliability while the most complete coverage possible critical portions, such as the connection to movable switch or rail parts, while the mechanical strength is improved and avoids the risk of blockage due to the ingress of fine dust or icing. In particular, the training according to the invention aims to ensure safe protection of sensitive parts of the point-setting system, even in the case of rough loads caused by track-laying installations. To achieve this object, the cover according to the invention essentially consists in providing a central tunnel-shaped lid open to the trough threshold with a substantially U-shaped cross-section, the axial length of which is dimensioned in the direction of the trough threshold such that a collision with displaceable switch parts, in particular tongues , Is avoided, and that with sliding switch parts in the direction of the same coupled cover caps are provided which engage the central tunnel-shaped cover over or under and are guided on this slidably. Due to the fact that a middle tunnel-shaped cover open to the trough surface is provided, a high degree of stability is initially ensured on account of the profile shape or the tunnel construction, whereby the essentially U-shaped cross section can be formed such that the width of the threshold does not touch any one Point is exceeded in order to ensure a secure support of the U-profile on the trough threshold while ensuring that collisions are avoided with Stopfarmen in a Nachstopfvorgang. In addition to this central, substantially U-shaped cross-section having tunnel-shaped lid whose axial length must be dimensioned in the direction of the trough threshold naturally so that a collision with the sliding switch parts can be ruled out with certainty, are now each side with the sliding switch parts respectively provided in the direction of displacement cover caps, whose axial length is chosen to be larger than the maximum adjustment of the switch parts to ensure a secure support on the central tunnel-shaped lid, wherein the formation is made such that the central tunnel-shaped lid is overlapped by the side covers and the caps are guided on the middle part. Such a construction is thus characterized by a particularly good protection of the sensitive connection points to the movable switch parts and also by a high degree of stability, the tunnel-like construction not only provides improved protection against mechanical influences but also against falling rock. The fact that condensation or rainwater can escape laterally at temperatures around freezing also reduces the risk of icing.
Mit Vorteil ist die erfindungsgemäße Ausbildung hierbei so getroffen, dass der mittlere tunnelförmige Deckel im Querschnitt nach außen konvex oder vieleckig ausgebildet ist und mit zwei im Wesentlichen normal zur Trogschwelle verlaufenden freien Schenkeln an der Trogschwelle abgestützt ist. Eine derartige Ausbildung erhöht die mechanische Steifigkeit und Stabilität. Um eine entsprechend friktionsarme Führung zu gewährleisten ist die Ausbildung mit Vorteil so getroffen, dass der mittlere tunnelförmige Deckel an seinen freien Schenkeln außen Führungsprofile trägt, welche mit entsprechenden innen liegenden Führungsprofilen der den mittleren tunnelförmigen Deckel übergreifenden seitlichen Abdeckkappen zusammenwirken. Aus Gründen der Stabilität kann bevorzugt der mittlere tunnelförmige Deckel aus Metall ausgebildet sein, wobei es durchaus ausreicht, wenn die seitlichen Abdeckkappen aus schlagfestem Kunststoff ausgebildet sind. Die relativ kurz bauenden seitlichen Abdeckkappen müssen somit lediglich aus entsprechend schlagfestem Kunststoff ausgebildet sein, um die notwendige mechanische Festigkeit zu gewährleisten, wobei gleichzeitig die Wahl eines entsprechenden Kunststoffs die Gefahr einer Vereisung wesentlich verringert.Advantageously, the inventive construction is made in this case that the central tunnel-shaped lid is convex or polygonal in cross-section outwardly and is supported with two substantially normal to the trough threshold extending free legs on the trough threshold. Such a design increases the mechanical rigidity and stability. In order to ensure a correspondingly low-friction guidance training is advantageously made so that the central tunnel-shaped lid carries on its free legs outside guide profiles, which cross-over with corresponding inner guide profiles of the central tunnel-shaped lid cooperate side covers. For reasons of stability, the central tunnel-shaped lid may preferably be formed of metal, wherein it is quite sufficient if the lateral cover caps are made of impact-resistant plastic. The relatively short-built side caps must therefore be formed only from suitably impact-resistant plastic to ensure the necessary mechanical strength, at the same time the choice of a corresponding plastic significantly reduces the risk of icing.
Mit Vorteil ist die Ausbildung so getroffen, dass die seitlichen Abdeckkappen quer zur Achse des Tunnels bzw. der Trogschwelle verlaufende Langlöcher, derartig Langlöcher aufweisende Träger oder Nuten tragen, in welche mit den beweglichen Schienenteilen verbundene Kupplungsglieder bzw. Bolzen eintauchen, sodass sichergestellt ist, dass bei einer Verschwenkung von Weichenteilen, wie beispielsweise von zungenschienen, ein entsprechender Bewegungsausgleich relativ zu den Abdeckkappen, welche lediglich geradlinig verschoben werden, gewährleistet wird. Die Langlöcher können hierbei in der Abdeckkappe selbst, in einem mit der Abdeckkappe verbundenen Träger, welcher beispielsweise schwenkbar an der Abdeckkappe festgelegt sein kann, oder lediglich als Nuten ausgebildet sein, wobei in diesem letzten Fall die Kupplungsglieder lediglich in die Nuten eingreifen und diese nicht wie im Falle der Langlöcher durchsetzen können.Advantageously, the training is such that the lateral caps wear transversely to the axis of the tunnel or the trough threshold elongated holes, such elongated having carriers or grooves, immersed in which connected to the movable rail parts coupling members or bolts, so as to ensure that at a pivoting of switch parts, such as tongue rails, a corresponding motion compensation relative to the caps, which are only moved straight, is guaranteed. The slots can in this case in the cap itself, in a cap connected to the support, which may be, for example, pivotally fixed to the cap, or only be formed as grooves, in which case the coupling members only engage in the grooves and not as in the case of slots can prevail.
Insbesondere die Ausbildung von Nuten ermöglicht unmittelbar eine Abdeckung bis über den Bereich des Anschlusses an die beweglichen Weichen- oder Kreuzungsteile und insbesondere die beweglichen Zungenschienen hinaus. Alternativ kann ein derartiger weiterer Schutz dadurch erzielt werden, dass die Langlöcher von Teilen der seitlichen Abdeckkappen vom Material der Abdeckkappen überdeckt sind.In particular, the formation of grooves allows immediate coverage beyond the area of the connection to the movable point or crossing parts and in particular the movable tongue rails addition. Alternatively, such a further protection can be achieved by covering the oblong holes of parts of the lateral covering caps with the material of the covering caps.
Insbesondere im Bereich von Zungenschienen ist der Weichenantrieb üblicherweise in oder an Trogschwellen festgelegt, welche auch Unterlagsplatten und einen entsprechenden Gleitstuhl tragen. Um hier im Zuge der Verstellbewegung auch seitlich einen möglichst dichtenden Abschluss zu gewährleisten ist mit Vorteil die Ausbildung so getroffen, dass die freien Schenkel der seitlichen Abdeckkappen in ihrer Höhe abgestuft und an jeweils verwendete Unterlagsplatten und/oder Gleitstühle angepasst sind.Especially in the field of tongue rails, the points drive is usually set in or on trough sleepers, which also carry base plates and a corresponding slide chair. To ensure here as possible in the course of the adjustment and the side as possible a sealing conclusion is advantageously made the training so that the free legs of the side covers are graded in height and adapted to each used underlay plates and / or Gleitstühle.
Die Erfindung wird nachfolgend anhand von in der Zeichnung schematisch dargestellten Ausführungsbeispielen näher erläutert. In dieser zeigen Fig.1 eine Draufsicht auf eine Trogschwelle mit der erfindungsgemäßen Ausbildung der Abdeckung, Fig.2 eine Seitenansicht in Richtung des Pfeils II der Fig.1 teilweise im Schnitt, Fig.3 einen Schnitt entsprechend der Linie III/III der Fig.2 durch die Abdeckung und die Trogschwelle, wobei der Übersichtlichkeit halber Weichenantriebsteile nicht dargestellt sind, Fig.4 ein Detail des Anschlusses der seitlichen Abdeckkappen an eine Zungenschiene, Fig.5 eine abgewandelte Ausbildung in analoger Darstellung wie Fig.4 und Fig.6 eine weitere abgewandelte Ausbildung des Anschlusses der seitlichen Abdeckkappen an den Weichenantrieb und die Zungenschiene einer Weiche.The invention will be explained in more detail with reference to embodiments shown schematically in the drawing. 2 is a side view in the direction of the arrow II of Figure 1 partially in section, Figure 3 shows a section along the line III / III of FIG. 2 through the cover and the trough threshold, where for the sake of clarity turnout drive parts are not shown, Figure 4 shows a detail of the connection of the side cover to a tongue rail, Figure 5 shows a modified training in an analogous representation as Figure 4 and Figure 6 another modified design of the connection of the side covers on the point drive and the tongue rail of a switch.
In Fig.1 ist eine mehrteilige Abdeckhaube ersichtlich, welche einen mittleren zur Trogschwelle 1 offenen tunnelförmigen Deckel 2 mit im Wesentlichen U-förmigem Querschnitt aufweist. Der tunnelförmige Deckel 2 wird von zwei seitlichen Abdeckkappen 3 umgriffen, wobei diese Abdeckkappen Langlöcher 4 tragen, in welche mit Zungenschienen 5 und damit beweglichen Weichenteilen verbundene Stellglieder im Eingriff stehen. Die Langlöcher 4 erlauben dabei eine entsprechende Ausgleichsbewegung von Bolzen oder Zapfen bei einer Ausdehnung und Verschiebung der Zungenschienen 5 in Richtung des Doppelpfeils 6 zu entsprechenden Backenschienen 7.In Figure 1, a multi-part cover is apparent, which has a central to the
Bei der Darstellung nach Fig.2 sind seitlich am mittleren nach unten offenen tunnelförmigen Deckel 2 angeordnete Führungen 8 ersichtlich, an welchen die seitlichen Abdeckungen 3 in Richtung des Doppelpfeils 9 verschieblich geführt sind. Die Mitnahme der seitlichen Abdeckungen mit der Verschiebebewegung der Zungenschienen 5 wird hier durch Zapfen 10 gewährleistet, welche die in Fig.1 ersichtlichen Langlöcher 4 durchsetzen. Bei der Darstellung in Fig.2 ist auch ersichtlich, dass die Unterkante der seitlichen Schenkel der seitlichen Abdeckungen 3 gestuft ausgebildet ist, um auf diese Weise Unterlagsplatten 11 bzw. Gleitstühle 12 in den anliegenden Positionen möglichst vollständig zu umgreifen, sodass auch seitlich ein hohes Maß an Abdichtung gewährleistet ist und ein ungehindertes Verschieben der Abdeckkappen 3 gemeinsam mit den Zungenschienen 5 ermöglicht wird.In the illustration according to Figure 2 are arranged laterally on the central downwardly open tunnel-
Aus der Darstellung nach Fig.3 ist ersichtlich, dass der innenliegende mittlere Teil des nach unten bzw. zur Trogschwelle 1 offenen tunnelförmigen Deckels 2 aus relativ dünnwandigem Metall ausgebildet sein kann und durch seine bombierte bzw. dachförmige Struktur ein hohes Maß an mechanischer Stabilität gewährleistet. Die seitlichen Abdeckungen 3 umgreifen diesen mittleren zur Trogschwelle offenen tunnelförmigen Deckel 2 und es sind die Führungen 8 ersichtlich, welche mit entsprechendem Gegenprofil in den seitlichen Abdeckungen 3 zusammenwirken. Die Führungsleisten 8 sind in ihrer Länge dabei so bemessen, dass die seitlichen verschiebbaren Abdeckungen in einfacher Weise eingeschoben werden können, wobei der feste mittlere Teil der tunnelförmigen Abdeckung auf die Trogschwelle aufgeklemmt sein kann und in einfacher Weise beispielsweise mit einem Schloss gegen eine Demontage gesichert werden kann. Der insgesamt im Wesentlichen trapezförmige Querschnitt überragt das Lichtraumprofil für die Stopfarme nicht, welche bei entsprechender Schrägstellung auch ohne Kollision mit einem derartigen Deckel zum Einsatz gelangen können.It can be seen from the illustration according to FIG. 3 that the inner middle part of the tunnel-
In Fig.4 ist die Ankopplung des Weichenantriebs an die seitlichen Abdeckkappen 3, wie sie bereits in Fig.1 und 2 ersichtlich war, im Detail dargestellt. Das Antriebsgestänge 13 trägt einen Zapfen 10, welcher zum einen unmittelbar über ein mit 15 schematisch angedeutetes Kupplungsglied mit der Zungenschiene 5 verbunden ist. Die Abdeckkappe 3 selbst trägt eine schwenkbare Platte 16 mit dem in Fig.1 und 2 bereits ersichtlichen Langloch 4, sodass nach dem Aufsetzen der Kappe 3 bzw. Aufschieben der Kappe 3 auf die Führungen 8 des mittleren Bereichs durch einfaches Verschwenken dieses plattenförmigen Bauteils 16 der Zapfen 10 unmittelbar in Eingriff mit dem Langloch 4 gelangt und auf die Art und Weise bei seiner Verstellbewegung in Richtung des Doppelpfeils 9 die Abdeckkappe 3 entsprechend mitnimmt.In Figure 4, the coupling of the point machine to the
Bei der Darstellung nach Fig.5 und 6 sind abweichende Abbildungen getroffen, bei welchen ein mit der Abdeckkappe 3 verbundener flexibler Fortsatz 17 den Bereich der Ankopplung an die Zungenschiene 5 weiter überdeckt und auf die Art und Weise einen erweiterten Schutz darstellt. Bei der Darstellung nach Fig.5 greift der aufwärts weisende Zapfen 10 des Weichengestänges 13 in eine Nut 18 ein und bewirkt auf diese Weise die Mitnahme der Abdeckkappe 3. Bei der Darstellung nach Fig.6 trägt die Abdeckkappe 3 einen entsprechenden Bolzen 19, welcher selbst wiederum mit einem Langloch eines plattenförmigen Zwischenglieds 14, welches am aufwärts gerichteten Zapfen 10 des Weichengestänges 13 angreift, verbunden ist. Insgesamt handelt es sich hier somit um eine Art kinematischer Umkehr, bei welcher das Langloch 4 in einem von Zapfen 10 getragenen Teil untergebracht ist. Mit Rücksicht auf die Zulässigkeit eines Spiels bei der Bewegung der seitlichen Abdeckungen 3 kann aber die Platte 14 auch mit Rundlöchern ausgebildet sein und bei einer Verschwenkung der Zungenschiene 5 entsprechend einen Ausgleich durch Verschwenkung relativ zur Achse des Zapfens 10 gewährleisten, um die lineare Mitnahme der Abdeckung 3 zu ermöglichen.In the illustration according to FIGS. 5 and 6 deviating illustrations are made, in which a
Der verschiebbare Abdeckteil 3 wird in allen Fällen auf den jeweiligen Zapfen 10 bzw. Flansch des Gestänges aufgesteckt.The
Insgesamt wird eine weitestgehende Abdeckung in kritischen Bereichen gewährleistet, sodass keine Fremdkörper in den Bereich der Angriffsstücke bzw. des Antriebs gelangen können.Overall, the greatest possible coverage in critical areas is ensured, so that no foreign bodies can get into the area of the attack pieces or the drive.
