Abstract

In a device to ease the change movement for movable rails or track parts (7, 7'), in particular of tongue rails, in which the rails (7, 7') are supported during the change operation by rollers (10, 10') pressed resiliently against the bottom edge of the rail foot, the rollers (10, 10') are pressed, in at least one end position (7, 7') of the change movement, resiliently onto a lateral edge (14, 15) of the rail foot. This makes it possible to combine the advantages of a reduction in the sliding friction during the change movement by means of a rolling friction with a flexible end-position securing of the respective adjustment position of the movable rail or track parts (7, 7') (Fig. 1). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Einrichtung zum Erleichtern der Umstellbewegung von beweglichen Schienen oder Schienenteilen, insbesondere von Zungenschienen, bei welcher die Schienen wahrend des Umstellvorganges über federnd gegen die Unterkante des Schienenfußes gedrückte Rollen abgestützt sind.The invention relates to a device for facilitating the changeover movement of movable rails or rail parts, in particular tongue rails, in which the rails are supported during the changeover process via rollers which are resiliently pressed against the lower edge of the rail foot.

Einrichtungen der eingangs genannten Art sollen die Umstellbewegung einer Schiene bzw. von Schienenteilen dadurch erleichtern, daß die Gleitreibung durch eine rollende Reibung ersetzt wird. Bei einer aus der DD-PS 56536 bekanntgewordenen Einrichtung der eingangs genannten Art ist eine federnde Rolle vorgesehen, welche im Bereich der Gleitstuhloberkante zur Wirkung gelangt. Während der Umstellbewegung soll offensichtlich durch die Kraft der Feder der bewegliche Schienenteil bzw. die bewegliche Schiene so weit vom Gleitstuhl abgehoben werden, daß der bewegliche Schienenteil bzw. die bewegliche Schiene ausschließlich über die Rolle bewegt wird, wobei die Rolle um ihre Achse verdreht wird. Bei einem Befahren der Schiene bzw. des Schienenteiles erfolgt aber aus Sicherheitsgründen eine Abstützung an der Oberfläche des Gleitstuhles, um eine Überlastung derartiger Rollen zu vermeiden. Derartige Rollen sind somit nur während der Verstellbewegung wirksam und müssen bei Befahren der beweglichen Schienenteile so weit nachgiebig und im bekannten Fall entgegen der Kraft einer Feder verschwenkbar gelagert sein, daß sie außer Wirkung gelangen.Devices of the type mentioned are said to facilitate the changeover movement of a rail or of rail parts in that the sliding friction is replaced by a rolling friction. In a device of the type mentioned at the beginning of DD-PS 56536, a resilient roller is provided, which comes into effect in the area of the upper edge of the sliding chair. During the changeover movement, the movable rail part or the movable rail should obviously be lifted so far from the sliding chair by the force of the spring that the movable rail part or the movable rail is moved exclusively over the roller, the roller being rotated about its axis. When driving on the rail or the rail part, however, for safety reasons there is a support on the surface of the sliding chair in order to avoid overloading such rollers. Such rollers are thus only effective during the adjustment movement and must be so flexible when driving on the movable rail parts and, in the known case, pivotable against the force of a spring that they come into effect.

Bei einer weiteren bekannten Einrichtung der eingangs genannten Art wird auf eine federnde Abstützung der Rolle verzichtet. Aus der DE-PS 314 265 ist eine Ausbildung eines Gleitstuhles bekanntgeworden, bei welcher neben dem Gleitstuhl eine Rolle derart angeordnet ist, daß bei einer Verstellung eines beweglichen Schienenteiles oder einer beweglichen Schiene durch Auflaufen des beweglichen Schienenteiles auf eine Rolle zunächst ein Anheben der beweglichen Schiene bzw. des Schienenteiles erfolgt, wobei die Anordnung so getroffen sein muß, daß am jeweiligen Ende des Verschiebeweges der Schiene bzw. des Schienenteiles dieselben wiederum zur Gänze von der Rolle auf den Gleitstuhl abgelaufen sind und am Gleitstuhl ruhen. Bei einer derartigen Ausbildung ist naturgemäß die Verstellkraft zu Beginn wesentlich größer, weil nicht nur die Gleitreibung auf der Oberfläche des Gleitstuhles sondern auch die Schwerkraft durch Anheben der Schiene auf die Rolle überwunden werden muß, bevor eine Erleichterung der Verstellbewegung erfolgt. Weiters muß eine derartige Ausbildung relativ exakt dimensioniert werden, um sicherzustellen, daß der bewegliche Schienenteil bzw. die bewegliche Schiene in der jeweiligen Betriebslage nicht mit der Rolle kollidiert, da diese sonst zerstört werden könnte.In another known device of the type mentioned, a resilient support of the roller is dispensed with. From DE-PS 314 265 a design of a sliding chair has become known, in which a roller is arranged next to the sliding chair in such a way that when the movable rail part or a movable rail is adjusted by running the movable rail part onto a roller, the movable rail is first raised or the rail part takes place, the arrangement must be such that at the respective end of the displacement path of the rail or the rail part, in turn, have completely run off the roller onto the sliding chair and rest on the sliding chair. With such a design, the adjustment force is naturally much greater at the beginning, because not only the sliding friction on the surface of the sliding chair but also the gravity must be overcome by lifting the rail on the roller before the adjustment movement is facilitated. Furthermore, such a design must be dimensioned relatively precisely in order to ensure that the movable rail part or the movable rail does not collide with the roller in the respective operating position, since this could otherwise be destroyed.

Eine weitere vorbekannte Einrichtung ist der EP-A-495 160 zu entnehmen. Hier ist eine Mehrzahl von Rollen vorgesehen, wobei zwei Rollen an einem schwenkbaren zweiarmigen Hebel gelagert sind.A further known device can be found in EP-A-495 160. A plurality of rollers is provided here, two rollers being mounted on a pivotable two-armed lever.

Die Erfindung zielt nun darauf ab, eine Einrichtung der eingangs genannten Art zu schaffen, mit welcher die Vorteile einer Verringerung der Gleitreibung während der Umstellbewegung mit einer elastischen Endlagensicherung der jeweiligen Verstelllage der beweglichen Schienen oder Schienenteile verbunden ist. Zur Lösung dieser Aufgabe besteht die erfindungsgemäße Ausbildung im wesentlichen darin, daß die Rollen in wenigstens einer Endlage der Umstellbewegung unter der Wirkung einer Feder an eine Seitenkante des beweglichen Schienenteiles oder Schienenfußes gedrückt sind. Dadurch, daß die Rollen in wenigstens einer Endlage der Umstellbewegung federnd an eine Seitenkante des Schienenfußes gedrückt sind, wird in dieser Endlage eine federnd nachgiebige Verriegelung bewirkt, da eine der Federkraft entsprechende Kraftkomponente in Verriegelungsrichtung der Schiene bzw. des Schienenteiles an der Außenseite des Steges zur Wirkung gelangt. Auf Grund der federnden Verriegelung ist es bei einem Verstellen ohne weiteres möglich, diesen federnden Widerstand zu überwinden, wobei gleichzeitig nach dem Ausschwenken der Rollen aus ihrer Position an der Außenseite des Steges der Schiene unmittelbar anschließend eine rollende Reibung und damit eine erleichterte Verstellbewegung bewirkt werden kann.The invention now aims to provide a device of the type mentioned, with which the advantages of reducing the sliding friction during the changeover movement are connected with an elastic end position securing of the respective adjustment position of the movable rails or rail parts. To achieve this object, the design according to the invention essentially consists in that the rollers are pressed in at least one end position of the changeover movement under the action of a spring against a side edge of the movable rail part or rail foot. Characterized in that the rollers are resiliently pressed against a side edge of the rail foot in at least one end position of the changeover movement, a resilient locking is effected in this end position, since a force component corresponding to the spring force in the locking direction of the rail or of the rail part on the outside of the web Effect. Due to the resilient locking, it is easily possible to overcome this resilient resistance when adjusting, while at the same time after swiveling the rollers out of their Position on the outside of the web of the rail immediately afterwards a rolling friction and thus an easier adjustment movement can be effected.

Mit Vorteil ist die Ausbildung hiebei so getroffen, daß jeweils gesonderte Rollen für jede Seitenkante des Schienenfußes angeordnet sind. Auf diese Weise werden beide Endlagen einer beweglichen Schiene oder eines beweglichen Schienenteiles elastisch in einer Verriegelungsstellung abgestützt und es wird bei jeder Bewegung aus einer derartigen Verriegelungslage heraus unmittelbar eine rollende Abstützung bei der Umstellbewegung bewirkt. Um eine sichere elastische Abstützung der jeweiligen Endlage der Schienen oder der Schienenteile zu bewirken, ist die Ausbildung mit Vorteil so getroffen, daß die Rollen um eine Schwenkachse über einen Weg in Höhenrichtung schwenkbar angelenkt sind, welcher wenigstens einem Drittel, vorzugsweise der Hälfte der Höhe des Schienenfußes an der Seitenkante desselben entspricht.The training hiebei is advantageously made such that separate roles for each side edge of the rail foot are arranged. In this way, both end positions of a movable rail or a movable rail part are elastically supported in a locking position and a rolling support is brought about during the changeover movement with each movement from such a locking position. In order to ensure reliable elastic support of the respective end position of the rails or the rail parts, the design is advantageously made such that the rollers are pivoted about a pivot axis in a height direction which is at least a third, preferably half the height of the Rail foot corresponds to the same on the side edge.

Eine besonders einfache und vorteilhafte Konstruktion kann dadurch geschaffen werden, daß die Rollen für voneinander verschiedene Seitenkanten des Schienenfußes um eine gemeinsame Schwenkachse schwenkbar gelagert sind. Bei einer derartigen gemeinsamen Schwenkachse wird eine progressive Verriegelung beim Befahren der Schienen erzielt, da ja in diesen Fällen die jeweils auf die andere Rolle zur Wirkung kommende Vertikalkraft als zusätzliche Schwenkkraft in die jeweils abstützende Rolle zur Wirkung gebracht wird und den Anpreßdruck an der Außenseite des Schienenfußes erhöht.A particularly simple and advantageous construction can be created in that the rollers for different side edges of the rail foot are pivotally mounted about a common pivot axis. With such a common pivot axis, a progressive locking is achieved when driving on the rails, since in these cases the vertical force acting on the other roller is brought into effect as an additional pivoting force in the respective supporting roller and the contact pressure on the outside of the rail foot elevated.

Eine besonders einfache und ohne großen Platzbedarf realisierbare Konstruktion ist im wesentlichen dadurch gekennzeichnet, daß die Federn von zur Schwenkachse der Rollen konzentrisch angeordneten Schraubenfedern gebildet sind, deren freie Enden mit den Achsen der Rollen verbunden sind und mit Anschlägen für die Begrenzung des Schwenkweges zusammenwirken. Eine derartige Anordnung der Rollen mit konzentrisch angeordneten Schraubenfedern kommt im übrigen mit nur einer einzigen Schraubenfeder aus, an deren freien Enden jeweils die Rollen parallel zur Achse der Schraubenfedern verschwenkbar gelagert sein können, womit eine kleinbauende und auch nachträglich leicht nachrüstbare Einheit geschaffen wird. Eine weitere Erleichterung der Umstellbewegung kann dadurch erzielt werden, daß an den freien Enden der Federn jeweils zwei Rollen mit zueinander parallelen Achsen angeordnet sind, wobei eine einfache nachträgliche Anordnung an beliebigen Stellen dadurch erzielt werden kann, daß die Federelemente und die Rollen relativ zu den Gleitstühlen bzw. Gleitplatten in Schienenlängsrichtung versetzt angeordnet und mit Schwellen oder Schienen lösbar verbunden sind.A particularly simple construction that can be realized without requiring a large amount of space is essentially characterized in that the springs are formed by helical springs arranged concentrically with the pivot axis of the rollers, the free ends of which are connected to the axes of the rollers and interact with stops for limiting the pivoting path. Such an arrangement of the rollers with concentrically arranged coil springs also requires only a single coil spring, at the free ends of which the rollers can be pivoted parallel to the axis of the coil springs, thus creating a unit that is small in size and easy to retrofit afterwards. This can further facilitate the changeover movement are that at the free ends of the springs two rollers are arranged with mutually parallel axes, with a simple subsequent arrangement can be achieved at any point that the spring elements and the rollers are offset relative to the sliding chairs or sliding plates in the longitudinal direction of the rail and are releasably connected to sleepers or rails.

Um ein Klaffen von Zungenschienen auch in verschlußlosen Bereichen wirkungsvoll zu verhindern und insbesondere bei größerem Abstand der Schwellen eine sichere Positionierung des jeweiligen verschiebbaren Schienenteiles zu gewährleisten, ist mit Vorteil die Ausbildung so getroffen, daß die Federelemente und Rollen in oder an einem Träger angeordnet sind, welcher mit einer den Schienenfuß einer unbeweglichen Schiene umgreifenden Klaue quer zur Schienenlängsrichtung justierbar verbunden ist, wobei insbesondere dann, wenn die den Schienenfuß umgreifende Klaue über einen Spindeltrieb mit dem Träger verbunden ist, eine einfache Justierung ermöglicht wird.In order to effectively prevent gaping of tongue rails even in non-locking areas and to ensure secure positioning of the respective displaceable rail part, especially when the sleepers are at a greater distance, the design is advantageously made such that the spring elements and rollers are arranged in or on a carrier, which is adjustably connected transversely to the longitudinal direction of the rail with a claw encompassing the rail foot of an immovable rail, a simple adjustment being possible in particular when the claw encompassing the rail base is connected to the carrier via a spindle drive.

Bei korrekter Auslegung der erfindungsgemäßen Umstellhilfe wird auf diese Weise die bewegliche Schiene, insbesondere Zungenschiene durch die vorgespannte Feder während des Umstellvorganges von der Gleitplatte abgehoben, wodurch der Bewegungswiderstand wesentlich verringert wird. Der Umstellvorgang wird durch die gespeicherte Federkraft der einseitig anliegenden Rollen unterstützt, welche auf diese Weise federnd in ihrer Endlage gesichert werden. Die erfindungsgemäße Ausbildung ermöglicht ein einfaches Nachrüsten bestehender Weichen, wobei die Umstellhilfe an keine besonderen geometrischen Bedingungen geknüpft ist. Sie kann beispielsweise in Verbindung mit bekannten Gleitstühlen ohne besondere Adaptierungsarbeiten Verwendung finden. Insbesondere läßt sich durch die flexible Anbringbarkeit der erfindungsgemäßen Umstellhilfe auch dort eine präzisere Führung der beweglichen Schienenteile verwirklichen, wo diese nicht durch Verschluß- oder Stellglieder in eine korrekte Position gezwungen werden. Die federbelastete Rollvorrichtung kann aber auch an Schwellen festgelegt werden, wodurch eine besonders stabile Abstützung bewirkt wird.When the changeover aid according to the invention is correctly designed, the movable rail, in particular the tongue rail, is lifted from the slide plate by the prestressed spring during the changeover process, as a result of which the resistance to movement is substantially reduced. The changeover process is supported by the stored spring force of the rollers resting on one side, which in this way are resiliently secured in their end position. The design according to the invention enables existing switches to be easily retrofitted, the changeover aid not being linked to any particular geometric conditions. It can be used, for example, in connection with known sliding chairs without any special adaptation work. In particular, due to the flexible attachability of the changeover aid according to the invention, a more precise guidance of the movable rail parts can also be realized where these are not forced into a correct position by locking or actuating elements. The spring loaded Rolling device can also be fixed to sleepers, which results in a particularly stable support.

The resiliently mounted rollers 10 are mounted on the free arms 11 of a helical spring 12, wherein in the embodiment shown in FIGS. 1 and 2, two rollers 10 are in each case directly adjacent to one another and are provided with parallel axes 13.

In einer der beiden jeweiligen Endpositionen der beweglichen Schiene bzw. Zungenschiene 7 liegt ein Rollenpaar an einer Seitenkante bzw. Außenkante 14 des Schienenfußes der beweglichen Schiene 7 an, während das andere Rollenpaar durch den Schienenfuß in einer niedergedrückten Stellung gehalten ist, wie dies in Fig.1 mit vollen Linien für das rechte Paar von Rollen bzw. Walzen 10 dargestellt ist. Bei einer Umstellbewegung über einen nicht näher dargestellten Verstellantrieb der beweglichen Schiene 7 von der Position 7 in die Position 7' erfolgt nach einem Niederdrücken der in Fig.1 auf der linken Seite dargestellten Rollen ein geringfügiges Anheben der beweglichen Schiene 7 von der Oberfläche des Gleitstuhles 6, so daß die bewegliche Schiene 7 bei ihrer Verstellbewegung über die drehbar gelagerten Rollen bzw. Walzen 10 abgestützt ist. In der mit 7' bezeichneten Endposition gelangen die auf der rechten Seite nunmehr strichliert und mit 10' bezeichneten Rollen in Anlage an die zweite Seitenkante 15' des Schienenfußes, während das auf der linken Seite der Fig.1 angeordnete Rollenpaar durch den Schienenfuß niedergedrückt ist.In one of the two respective end positions of the movable rail or tongue rail 7, a pair of rollers lies against a side edge or outer edge 14 of the rail base of the movable rail 7, while the other pair of rollers is held in a depressed position by the rail base, as shown in FIG. 1 is shown with full lines for the right pair of rollers 10. In the case of a change-over movement via an adjustment drive of the movable rail 7, not shown, from the position 7 to the position 7 ', the movable rail 7 is slightly raised from the surface of the sliding chair 6 after the rollers shown in FIG , so that the movable rail 7 is supported during its adjustment movement via the rotatably mounted rollers 10. In the end position denoted by 7 ', the rollers now denoted by dashed lines and denoted by 10' come into contact with the second side edge 15 'of the rail foot, while the pair of rollers arranged on the left side of FIG. 1 is depressed by the rail foot.

Beim Befahren der Schienen liegt somit die bewegliche Schiene unmittelbar auf der Oberfläche des Gleitstuhles 6 auf, während bei einer Umstellbewegung ein geringfügiges Anheben der Schienen erfolgt und in dem Endlagen durch das Anliegen der Rollen bzw. Walzen 10 an jeweils einer Seitenkante 14 bzw. 15 des Schienenfußes der beweglichen Schiene 7 eine Unterstützung und Sicherung der Endposition erfolgt. Für eine entsprechende Sicherung der Endlage sind dabei die Rollen bzw. Walzen 10 in Höhenrichtung um einen Weg schwenkbar, welcher wenigstens einem Drittel der Höhe der Seitenkante 14 bzw. 15 des Schienenfußes entspricht. Die Verschwenkbewegung der freien Arme der die Rollen bzw. Walzen 10 tragenden Schraubenfedern in Höhenrichtung wird dabei durch schematisch angedeutete Anschläge 16 begrenzt.When driving on the rails, the movable rail thus lies directly on the surface of the sliding chair 6, while a slight lifting of the rails occurs during a changeover movement takes place and in the end positions by the abutment of the rollers or rollers 10 on each side edge 14 or 15 of the rail foot of the movable rail 7, the end position is supported and secured. For a corresponding securing of the end position, the rollers or rollers 10 can be pivoted in the height direction by a path which corresponds to at least one third of the height of the side edge 14 or 15 of the rail foot. The pivoting movement of the free arms of the coil springs carrying the rollers or rollers 10 in the vertical direction is thereby limited by schematically indicated stops 16.

Weiters kann der Schienenfuß im Bereich des Überganges in die Seitenkanten 14 bzw. 15 abgerundet bzw. abgeschrägt ausgebildet sein, um das Niederdrücken der Rollen 10 bei Beginn eines Umstellvorganges zu erleichtern und die Einnahme der Endposition zu unterstützen.Furthermore, the rail foot can be rounded or beveled in the region of the transition into the side edges 14 or 15 in order to facilitate the pressing down of the rollers 10 at the start of a changeover process and to support the assumption of the end position.

Durch Anordnung der Einrichtung zum Erleichtern der Umstellbewegung von beweglichen Schienen oder Schienenteilen an einer Schwelle unmittelbar der Gleitplatte benachbart, kann auch eine einfache Nachrüstung von bereits bestehenden Anlagen erfolgen, da keinerlei Adaptierungsarbeiten an den bereits im Einsatz befindlichen Bauteilen vorgenommen werden müssen und lediglich die Position der Rollen 10 auf die jeweilige Endlage der beweglichen Schiene abgestimmt werden muß. Dadurch, daß die Rollen an den freien Enden einer gemeinsamen Schraubenfeder 12 gelagert sind, ergibt sich jeweils eine Unterstützung der Bewegung über die Federvorspannung der jeweiligen freien Arme.By arranging the device to facilitate the changeover movement of movable rails or rail parts on a threshold directly adjacent to the slide plate, it is also possible to easily retrofit existing systems, since no adaptation work has to be carried out on the components already in use and only the position of the Rollers 10 must be matched to the respective end position of the movable rail. The fact that the rollers are mounted on the free ends of a common coil spring 12 results in a support of the movement via the spring preload of the respective free arms.

Bei der in den Fig.3 und 4 dargestellten Ausführungsform sind die Bezugszeichen der Fig.1 und 2 für gleiche Bauteile beibehalten worden. Es ist wiederum eine Gleitplatte 2 an einer Schwelle 5 festgelegt, wobei auf dieser Gleitplatte 2 ein Gleitstuhl 6 für eine bewegliche Schiene 7 angeordnet ist. Zum Unterschied von der vorangehenden Ausführungsform ist bei der Ausbildung gemäß den Fig.3 und 4 jeweils eine Schraubenfeder 17 vorgesehen, welche an jeweils einem freien Ende wiederum ein Paar von Rollen bzw. Walzen 10 trägt. Die Einrichtungen zum Erleichtern der Umstellbewegung von beweglichen Schienen oder Schienenteilen sind dabei zu beiden Seiten des Gleitstuhles 6 derart angeordnet, daß jeweils eine der durch das Zusammenwirken einer Feder 17 und der Rollen 10 gebildete Einrichtung eine Endlage der beweglichen Schiene 7 bzw. 7' sichert. Bei einer Bewegung der beweglichen Schiene 7 erfolgt wieder ein geringfügiges Anheben der Schiene von der Oberfläche des Gleitstuhles, so daß die Bewegung nur über eine rollende Reibung erfolgt. Wie in Fig.3 dargestellt, erfolgt wiederum eine Sicherung der Position der Schiene 7 durch ein Anliegen der Rolle an der Seitenkante 14 des Schienenfußes, während das andere Rollenpaar 10' in dieser Position durch den Schienenfuß niedergedrückt ist. In der Position 7' erfolgt die Sicherung der Endlage durch das in Fig.3 niedergedrückte Rollenpaar 10.In the embodiment shown in Figures 3 and 4, the reference numerals of Figures 1 and 2 have been retained for the same components. A sliding plate 2 is in turn fixed on a threshold 5, a sliding chair 6 for a movable rail 7 being arranged on this sliding plate 2. In contrast to the previous embodiment, the 3 and 4, a helical spring 17 is provided, which in turn carries a pair of rollers or rollers 10 at each free end. The devices for facilitating the changeover movement of movable rails or rail parts are arranged on both sides of the sliding chair 6 such that one of the devices formed by the cooperation of a spring 17 and the rollers 10 secures an end position of the movable rail 7 and 7 '. When the movable rail 7 moves, the rail is again slightly raised from the surface of the sliding chair, so that the movement takes place only via rolling friction. As shown in FIG. 3, the position of the rail 7 is in turn secured by the roller resting against the side edge 14 of the rail base, while the other pair of rollers 10 'is pressed down in this position by the rail base. In position 7 ', the end position is secured by the pair of rollers 10 depressed in FIG.

Durch die getrennte Anordnung der Rollen 10 können die Justiermöglichkeiten und Anpassungsmöglichkeiten weiter vereinfacht werden, da mit einer lageveränderlichen Befestigung einer einheitlichen Einrichtung an der Schwelle entsprechend des Verschiebeweges der beweglichen Schiene, beispielsweise Zungenschiene, 7 die Positionierung der Rollvorrichtung bzw. Umstellhilfe vorgenommen werden kann. Anstelle der dargestellten Schraubenfedern können auch beispielsweise Blattfedern verwendet werden.Due to the separate arrangement of the rollers 10, the adjustment and adjustment options can be further simplified since the positioning of the rolling device or changeover aid can be carried out with a positionally variable fastening of a uniform device on the threshold corresponding to the displacement path of the movable rail, for example tongue rail, 7. Instead of the coil springs shown, leaf springs can also be used, for example.

In den Fig.5 und 6 ist eine Ausführungsform dargestellt, wobei die Festlegung der Einrichtung zum Erleichtern der Umstellbewegung nicht an einer Schwelle bzw. einer Unterlagsplatte erfolgt, sondern wobei ein Träger 18 mit einer den Schienenfuß 19 der unbeweglichen Schiene bzw. Backenschiene 1 umgreifenden Klaue 20 verbunden ist. Der Träger 18 trägt wiederum beispielsweise eine Schraubenfeder 21, welche an ihren freien Enden drehbare Rollen 10 trägt. In der dargestellten Endlage 7' einer beweglichen Schiene bzw. Zungenschiene erfolgt wiederum eine Sicherung über die in der Zeichnung dargestellte rechte Rolle. Diese rechte Rolle ist, strichliert und mit 10' bezeichnet, in Fig.5 in einer Position dargestellt, in welcher sich die Schiene in der zweiten Endposition befindet.5 and 6, an embodiment is shown, wherein the device for facilitating the changeover movement is not fixed on a threshold or a base plate, but rather a carrier 18 with a claw encompassing the rail foot 19 of the immovable rail or stock rail 1 20 is connected. The carrier 18 in turn carries, for example, a coil spring 21 which carries rotatable rollers 10 at its free ends. In the end position shown 7 'of a movable rail or tongue rail is again secured via the right roller shown in the drawing. This right-hand roller, dashed and designated 10 ', is shown in FIG. 5 in a position in which the rail is in the second end position.

Durch eine derartige Anordnung einer die unbewegliche Schiene umgreifenden Klaue 20, welche mit dem Träger 18 für die Umstellhilfe verbunden ist, kann auch in Bereichen, in welchen keine Schwellen vorgesehen sind, eine entsprechende Sicherung der beweglichen Schiene und eine entsprechende Umstellhilfe vorgesehen werden. Für eine Anpassung und Justierung der Position des Trägers 18 an die jeweilige Endposition kann zwischen der Klaue 20 und dem Träger 18 ein Spindeltrieb angeordnet sein, wie er schematisch mit 22 angedeutet ist.Such an arrangement of a claw 20 encompassing the immovable rail, which is connected to the carrier 18 for the changeover aid, can also provide a corresponding securing of the movable rail and a corresponding changeover aid in areas in which no sleepers are provided. For adaptation and adjustment of the position of the carrier 18 to the respective end position, a spindle drive can be arranged between the claw 20 and the carrier 18, as indicated schematically by 22.
