Abstract

The proposal is for a crossing nose (10) arranged substantially at a distance from a substrate between positions on wing rails (12, 14).

Description

Die Erfindung bezieht sich auf eine Herzstückspitze, die mit ihrer Unterseite zwischen Flügelschienen auf einer Unterlage wie Gleitstuhl beweglich angeordnet ist und bei an einer der Flügelschienen anliegender Stellung bzw. Endstellung vorzugsweise mittels zumindest einer von einem Verschlußteil geführt aufgenommenen Verschlußklammer verriegelbar ist.The invention relates to a frog tip, with its underside between Wing rails are movably arranged on a base such as a sliding chair and at one of the wing rails adjacent position or end position preferably by means of at least one locking clip received guided by a locking part can be locked.

Die bekannten beweglichen Herzstückspitzen werden auf einem Gleitstuhl zwischen ihren Endstellungen hin und her bewegt, um sodann verriegelt zu werden, wenn sie an einer Flügelschiene anliegen. Durch das Verschieben auf dem Gleitstuhl bedingt ist es erforderlich, daß eine häufige Überprüfung und Wartung erforderlich ist. Insbesondere sind häufig Schmierarbeiten erforderlich, wobei der Schmierstoff selbst zu einer Umweltbelastung führen kann; vgl. "Die Eisenbahnschiene", Verlag von Wilhelm Ernst & Sohn, Berlin, München, Düsseldorf, 1977, Seiten 336 und 337.The well-known movable centerpiece tips are on a sliding chair between their end positions moved back and forth to be locked when they are on a wing rail. It is due to the sliding on the sliding chair Requires frequent inspection and maintenance. Especially lubrication work is often required, the lubricant itself becoming one Can cause environmental pollution; see. "Die Eisenbahnschiene", published by Wilhelm Ernst & Sohn, Berlin, Munich, Düsseldorf, 1977, pages 336 and 337.

Der vorliegenden Erfindung liegt das Problem zugrunde, eine Herzstückspitze der eingangs beschriebenen Art so weiterzubilden, daß eine Reduzierung der Wartung möglich ist, ohne daß konstruktiv aufwendige Maßnahmen oder besondere Materialien für Unterlage und Herzstückspitze erforderlich sind.The present invention is based on the problem of a frog tip type described in the beginning so that a reduction in maintenance is possible without constructively complex measures or special materials are required for the pad and the centerpiece tip.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die Herzstückspitze in ihren an den Flügelschienen anliegenden Stellungen auf der Unterlage abgestützt und zwischen den an den Flügelschienen anliegenden Stellungen beabstandet zur Unterlage angeordnet ist. According to the invention the object is achieved in that the frog tip in their positions on the wing rails supported by the pad and between the positions on the wing rails is spaced from the base.

Erfindungsgemäß wird vorgeschlagen, daß die Herzstückspitze nur in den Endstellungen, also in den verriegelten Zuständen, auf der Unterlage wie Gleitstuhl abgestützt ist, wohingegen beim Verschieben von der einen zu der anderen Endstellung eine Beabstandung zu der Unterlage erfolgt. Hieraus resultiert eine Wartungsreduzierung unter gleichzeitiger Einsparung von Schmiermitteln.According to the invention it is proposed that the frog tip only in the end positions, So in the locked states, on which the support is supported like a sliding chair, whereas when moving from one to the other end position one Distance to the document is made. This results in a reduction in maintenance while saving lubricants.

Zwar war es z.B. gemäß der US 2,533,929 bereits nahezu 50 Jahre bekannt, Weichenzungen während ihres Verstellens zu einer Unterlage wie Gleitstuhl zu beabstanden, ohne daß ein entsprechender Vorschlag für Herzstückspitzen zur Anwendung gelangte. Aus der EP 0 495 160 A1 ist ebenfalls ein sich allein auf Zungenschienen beziehender Vorschlag bekannt, um diese beim Verstellen mittels einer Wippe anheben zu können.It was e.g. Already known for almost 50 years according to US 2,533,929, switch tongues during their adjustment to a base such as a sliding chair without a corresponding proposal for centerpiece tips was used. From EP 0 495 160 A1, a proposal relating only to tongue rails is also known, um to be able to lift them when adjusting using a rocker.

Eine Weiterbildung der Erfindung sieht vor, daß fußseitig von der Herzstückspitze mittelbar oder unmittelbar ein Element ausgeht, das einen sich entlang oder in etwa entlang der Mittelachse der Herzstückspitze erstreckenden Vorsprung aufweist, und daß das Element mit einem Rollenelement wechselwirkt, dessen Mittelachse in oder in etwa in einer zwischen den Flügelschienen verlaufenden Symmetrieebene verläuft. Dabei kann das Element rollenelementseitig eine Fläche aufweisen, die aus zwei äußeren konkav verlaufenden Abschnitten und einem mittleren vorzugsweise plateauartigen Abschnitt zusammengesetzt ist, der den Vorsprung bildet.A further development of the invention provides that the foot of the frog tip directly or indirectly an element that runs along or roughly has projection extending along the central axis of the frog tip, and that the element interacts with a roller element, the central axis of which is approximately or approximately runs in a plane of symmetry running between the wing rails. It can the element on the roller element side have a surface that consists of two outer concaves extending sections and a middle preferably plateau-like section is composed, which forms the projection.

Durch das Zusammenwirken der Elemente wird die Herzstückspitze dann angehoben und somit zur Unterlage beabstandet, wenn der Vorsprung bzw. dessen Flanken über das Rollenelement gleitet.Through the interaction of the elements, the centerpiece tip is then raised and thus spaced from the base when the projection or its flanks over the Roller element slides.

Um stoßartige Bewegungen auszuschließen, die zu einem Verschleiß führen könnten, ist des weiteren vorgesehen, daß die Krümmungsradien der äußeren Abschnitte zumindest in dem Bereich der an den mittleren Abschnitt angrenzt, dem oder in etwa dem Krümmungsradius des Rollenelementes entsprechen.To rule out jerky movements that could lead to wear further provided that the radii of curvature of the outer portions at least in the area adjacent to the central section, or approximately the radius of curvature correspond to the roller element.

Selbstverständlich besteht auch die Möglichkeit, das Rollenelement und das von der Herzstückspitze ausgehende Element auszutauschen.Of course, there is also the possibility of the roller element and the Exchanging outgoing element centerpiece tip.

Das Rollenelement ist vorzugsweise auf zumindest zwei Federelementen unterschiedlicher Kennlinien abgestützt ist, wobei das eine Federelement eine im wesentlichen konstante Steifigkeit und das andere Federelement eine veränderliche Steifigkeit aufweist und die Federelemente derart mechanisch miteinander gekoppelt sind, daß bei durch die Herzstückspitze belastetem Rollenelement jedes Federelement einen wirksamen Federweg aufweist. Insbesondere zeichnet sich die Erfindung dadurch aus, daß sich die Federelemente auf gegenüberliegenden Seiten eines Trägerelementes erstrecken und über ein Verbindungselement wie Schraube abstandsveränderbar zueinander einstellbar sind, daß das eine Dämpfung bewirkende Federelement mit der veränderlichen Steifigkeit auf der der Herzstückspitze abgewandten Seite des Trägerelementes verläuft, daß das Federelement mit der veränderlichen Steifigkeit bei unbelastetem Rollenelement derart durch das Verbindungselement gegen das Tragelement angezogen ist, daß eine Federwirkung ausgeschlossen oder im wesentlichen ausgeschlossen ist, und daß bei belastetem Rollenelement jedes der Federelemente übliche zusätzliche Be- und Entlastungen des Rollenelementes aufnehmende Federweglängen aufweist.The roller element is preferably different on at least two spring elements Characteristic curves is supported, with the one spring element essentially constant rigidity and the other spring element has a variable rigidity and the spring elements are mechanically coupled to one another in such a way that when Centerpiece loaded roller element each spring element an effective Has travel. In particular, the invention is characterized in that the Spring elements extend on opposite sides of a carrier element and over a connecting element such as a screw can be adjusted in such a way that the distance between them can be adjusted that the damping effecting spring element with the variable rigidity the side of the carrier element facing away from the frog tip runs that the Spring element with the variable rigidity in such a way when the roller element is not loaded is attracted by the connecting element against the support member that a Spring action is excluded or essentially excluded, and that at loaded roller element of each of the spring elements usual additional loading and Has relief of the roller element receiving spring travel lengths.

Bei den Federelementen handelt es sich einerseits um eine Tragfeder und andererseits um eine Dämpfungsfeder, wobei zumindest letztere, vorzugsweise jedoch beide Elastomerfedern sind. Die Dämpfungsfeder weist dabei eine Steifigkeit auf, die vorzugsweise zehnmal kleiner als die der Tragfeder ist.The spring elements are, on the one hand, a suspension spring and, on the other hand a damping spring, at least the latter, but preferably both elastomer springs are. The damping spring has a rigidity that is preferably is ten times smaller than that of the suspension spring.

Beim Vorspannen der Federelemente, also dann, wenn das Rollenelement nicht belastet ist, wird die Dämpfungsfeder auf Block oder nahezu auf Block eingestellt, um sodann bei durch die Herzstückspitze belastetem Rollenelement in eine Arbeitsstellung zu gelangen (Arbeitspunkt), die es ermöglicht, daß bei üblichen Be- und Entlastungen des Rollenelementes durch auf dieses einwirkender Herzstückspitze der Vorspannungspunkt, also die Blockstellung nicht erreicht wird.When prestressing the spring elements, i.e. when the roller element is not loaded is, the damping spring is set to block or almost to block, then with the roller element loaded by the centerpiece tip into a working position get (working point), which makes it possible that the usual Roller element by the bias point acting on this centerpiece tip, thus the block position is not reached.

Im Arbeitspunkt erfolgt durch die Dämpfungsfeder eine Federung und damit Dämpfung in beiden Richtungen, so daß ein Aufschlagen der Herzstückspitze auf eine Unterlage wie Gleitstuhl ausgeschlossen wird. Gleichzeitig wird aufgrund der Dämpfungseigenschaften der Dämpfungsfeder ein schneller Schwingungsabbau in der Herzstückspitze selbst hervorgerufen. At the operating point, the damping spring provides suspension and thus damping in both directions, so that the tip of the frog hits a surface how sliding chair is excluded. At the same time due to the damping properties the damping spring quick vibration reduction in the centerpiece tip itself evoked.

Durch die Steifigkeit der Tragfeder wird die Arbeitsstellung der Rollenelemente vorgegeben, das heißt das Niveau, auf dem die Herzstückspitze zu ruhen kommt.The working position of the roller elements is determined by the rigidity of the suspension spring, that is, the level at which the centerpiece tip rests.

Sofern das den Vorsprung aufweisende Element mittelbar oder unmittelbar von der Herzstückspitze ausgeht, wird dieses vorzugsweise durch einen quaderförmigen Abschnitt von Verschlußklammeraufnahmen mit der Herzstückspitze verbindenden Halterungen gebildet.Provided that the element having the projection is directly or indirectly from the Centerpiece tip, this is preferably a cuboid Section of locking clip receptacles connecting the frog tip Brackets formed.

Selbstverständlich besteht auch die Möglichkeit, die Herstückspitzenunterseite nur mit einem oder mehrere Rollenelemente wechselwirken zu lassen, um die erfindungsgemäße Lehre zu realisieren.Of course, there is also the option of using the bottom of the tip only to interact with one or more roller elements in order to achieve the invention To realize teaching.

Ein weiterer Lösungsvorschlag sieht vor, daß unterhalb der Herzstückspitze zumindest eine diese abstützende Wippe angeordnet ist, dessen Drehachse in oder in etwa in zwischen den Flügelschienen verlaufender Symmetrieebene liegt. Dabei weist die Wippe einen geradlinigen oder gewinkelten Balken mit symmetrisch zur Drehachse angeordneten und mit der Herzstückspitzenunterseite wechselwirkenden, im Durchmesser gleichgroßen Rollen auf.Another proposed solution provides that below the centerpiece tip at least one rocker supporting this is arranged, the axis of rotation of which is in or in lies approximately in the plane of symmetry running between the wing rails. It points the rocker is a straight or angled bar with symmetry to the axis of rotation arranged and interacting with the centerpiece top underside, in diameter equally large roles.

Sofern der Herzstückspitze zwei oder mehrere Wippen zugeordnet sind, sollten bei gleichen Abmessungen dieser deren Drehachsen in äquidistanten Abständen zueinander bzw. zu den innenliegenden Längsrändern der Flügelschienen verlaufen, betrachtet in einer Ebene senkrecht zu den Drehachsen.If two or more rockers are assigned to the centerpiece tip, you should use same dimensions of their axes of rotation at equidistant distances from each other or to the inner longitudinal edges of the wing rails, viewed in a plane perpendicular to the axes of rotation.

Durch die erfindungsgemäßen Maßnahmen rollt die Herzstückspitze auf den Rollenelementen bei deren Verschieben ab, wobei ein Verschwenken während des Bewegens von einer Endstellung in die andere Endstellung mit dem Ergebnis erfolgt, daß die Herzstückspitze zur Unterlage beabstandet ist. The centerpiece tip rolls on the roller elements by the measures according to the invention when moving off, with a pivoting during movement from one end position to the other end position with the result that the Centerpiece tip is spaced from the base.

Insbesondere liegt die Herzstückspitze bei an einer der Flügelschienen anliegender Stellung auf dem der Flügelschiene naheliegenden Rollenelement auf und berührt mit ihrem der Flügelschiene abgewandten Längsrand das andere Rollenelement.In particular, the frog tip lies against one of the wing rails Position on the roller element close to the wing rail and touches with the other roller element on its longitudinal edge facing away from the wing rail.

Ein weiterer Vorschlag der Erfindung sieht vor, daß die Verschlußklammer vorzugsweise in Längsrichtung der Herzstückspitze verschiebbar von einer mit der Herzstückspitze verbundenen Verschlußklammeraufnahme ausgeht, daß von der Verschlußklammer zumindest ein Rollenelement ausgeht, das von einem das Verschlußstück durchsetzenden, senkrecht oder nahezu senkrecht zur Herzstückspitzenlängsachse verschiebbaren Schiebeelement erfaßbar ist, und daß das Rollenelement auf einer parallel oder in etwa parallel zur Verschieberichtung des Schiebeelementes verlaufenden Auflage abstützbar ist, die ihrerseits ortsfest zum Verschlußstück angeordnet ist oder von diesem ausgeht. Dabei ist bei verriegelter Herzstückspitze das Rollenelement in einer von dem Schiebeelement und der Auflage zumindest bereichsweise begrenzten Aufnahme gehalten, so daß ein sicheres Anliegen der Herzstückspitze an einer der Flügelschienen gewährleistet ist.Another proposal of the invention provides that the locking clip preferably in the longitudinal direction of the frog tip slidably from a locking clip receptacle connected to the frog tip assumes that at least one roller element extends from the closure clip, which of one passing through the closure piece, perpendicular or almost perpendicular to Centerpiece longitudinal axis displaceable sliding element is detectable, and that that Roller element on a parallel or approximately parallel to the direction of displacement Sliding element extending support is supported, which in turn is stationary for Closure piece is arranged or starts from this. Here is locked Centerpiece tip the roller element in one of the sliding element and the support at least partially limited recording, so that a safe concern the centerpiece tip is guaranteed on one of the wing rails.

Um sicherzustellen, daß beim Verschieben von einer Endstellung in die andere Endstellung ein Anheben der Herzstückspitze von der Unterlage erfolgt, ist vorgesehen, daß beim Verschieben der Herzstückspitze das Rollenelement von einem rampenförmigen Abschnitt des Schiebeelementes erfaßt und angehoben wird.To ensure that when moving from one end position to the other It is provided that the tip of the frog is raised from the base. that when moving the frog tip, the roller element of a ramp-shaped Section of the sliding element is detected and raised.

Das Rollenelement selbst geht vorzugsweise von einem unterhalb einer der Flügelschienen zugeordneter Verschlußschiene verlaufenden Schenkel der Verschlußklammer aus. Insbesondere ist vorgesehen, daß von dem Schenkel zwei Rollenelemente ausgehen und daß jeweils ein Rollenelement im Endbereich des Schenkels angeordnet ist.

In den Figuren, in denen grundsätzlich gleiche Elemente mit den gleichen Bezugszeichen versehen sind, sind Vorschläge für bewegliche Herzstückspitzen (10) dargestellt, wobei die Herzstückspitze (10) während des Verschiebens von einer ersten Endstellung, in der die Herzstückspitze an einer Flügelschiene (12) anliegt, in eine zweite Endstellung, in der die Herzstückspitze an einer Flügelschiene (14) anliegt, zu einer nicht dargestellten Unterlage wie Gleitstuhl beabstandet ist. Durch die erfindungsgemäßen Vorschläge wird sichergestellt, daß die Herzstückspitze (10) allein in den Endstellungen auf der Unterlage aufliegt, jedoch während der Bewegung zu dieser beabstandet ist. In the figures, in which basically the same elements with the same reference numerals are provided, proposals for movable frog tips (10) are shown, wherein the centerpiece tip (10) during the displacement from a first end position in which the centerpiece tip rests on a wing rail (12), in a second end position, in which lies at the centerpiece tip on a wing rail (14), to a not shown Underlay how the sliding chair is spaced. Through the proposals according to the invention ensures that the centerpiece tip (10) alone in the end positions on the base rests, but is spaced from it during the movement.

Um dies nach dem Ausführungsbeispiel der Fig. 1 und 2 zu ermöglichen, werden die Herzstückspitze (10) verriegelnde Verriegelungseinrichtungen nachstehenden Aufbaus benutzt.To make this possible according to the embodiment of FIGS. 1 and 2, the Centerpiece tip (10) interlocking locking devices of the following structure used.

Über Verbindungsbleche (16) und (18) sind mit der Herzstückspitze (10) Verschlußklammeraufnahmen (20) und (22) verbunden, von denen jeweils um eine parallel zur Längsachse der Herzstückspitze verlaufende Achsen (24) und (26) drehbare Klammern (28) und (30) ausgehen, die Verschlußstücke (32) und (34) durchsetzen, die von den Flügelschienen (12) und (14) zugeordneten Verschlußschienen (36) bzw. (38) oder anderen Befestigungen ausgehen. Die Klammern (28) und (30) sind außerdem in Längsrichtung der Verschlußschienen (36) verschiebbar.Locking plate receptacles are attached to the frog tip (10) via connecting plates (16) and (18) (20) and (22), each of which is parallel to the Axes (24) and (26) rotating clamps running along the longitudinal axis of the frog tip (28) and (30) go out, push through the locking pieces (32) and (34) by the Wing rails (12) and (14) associated closure rails (36) and (38) or other fasteners. The brackets (28) and (30) are also in Movable in the longitudinal direction of the locking rails (36).

Von den Verschlußstücken (32) und (34) wird ferner ein Schieber (40) aufgenommen, durch den die Verschlußklammern (28) und (30) erfaßt werden, um die Herzstückspitze (10) von der einen in die andere Endstellung zu verschieben und gleichzeitig während des Verschiebens von dem Gleitstuhl abzuheben. Auch geht von den Verschlußstücken (32), (34) eine als Laufbahn zu bezeichnende Auflage (42) ortsfest aus.A slide (40) is also received from the closure pieces (32) and (34), through which the locking clips (28) and (30) are grasped around the frog tip (10) to move from one end position to the other and at the same time during of sliding off the sliding chair. Also goes from the closures (32), (34) a support (42) to be designated as a career.

Die Klammern (28) und (30) besitzen jeweils einen sich unterhalb der Verschlußschiene (36) bzw. (38) erstreckenden Schenkel (44) bzw. (46), der in seinen Endbereich Rollen (48), (50) bzw. (52), (54) aufweist, die einerseits auf der Laufbahn (42) entlangrollen und andererseits von dem Schieber (40) erfaßt werden.The brackets (28) and (30) each have one below the locking rail (36) or (38) extending leg (44) or (46), which rolls in its end region (48), (50) or (52), (54), which on the one hand roll along the track (42) and on the other hand can be detected by the slide (40).

Da der Schieber (40) vorzugsweise aus zwei parallel zueinander verlaufenden Schenkeln besteht, zwischen denen die Laufbahn (42) verläuft, weisen die Rollenelemente (48), (50), (52), (54) Rollen mit unterschiedlichen Durchmessern auf, um stets eine rollende Bewegung sicherzustellen.Since the slide (40) preferably consists of two legs running parallel to one another there is between which the raceway (42) runs, the roller elements (48) have (50), (52), (54) rolls with different diameters to always have a rolling Ensure movement.

Um das Verschieben des Schiebers (40) weitgehend reibungsfrei zu gestalten, ist der Schieber (40) auf Rollen (56) und (58) abgestützt, die an der Auflage (42) gelagert sind. Um ein unkontrolliertes Anheben des Schiebers (40) auszuschließen, liegen an der Oberseite des Schiebers (40) Rolien (60) und (62) an, die von den Verschlußstücken (32), (34) ausgehen.In order to make the sliding of the slide (40) largely smooth, the Slide (40) supported on rollers (56) and (58) which are mounted on the support (42). To rule out an uncontrolled lifting of the slide (40), lie on the Top of the slide (40) Rolien (60) and (62) by the locking pieces (32), (34).

Wie die Fig. 1 und 2 verdeutlichen, weist der Schieber (40) kanalartige und in entgegengesetzte Richtungen verlaufende Aufnahmen (64), (66) bzw. (68), (70) für die Rollen (48) und (50) bzw. (52) und (54) auf, wobei die Kanäle (64), (66), (68) und (70) jeweils von unteren rampenförmigen Flanken begrenzt sind, die die Bezugszeichen (72), (74), (76) und (78) aufweisen.1 and 2 illustrate, the slide (40) has channel-like and in opposite Directional receptacles (64), (66) and (68), (70) for the rollers (48) and (50) or (52) and (54), with the channels (64), (66), (68) and (70) each are delimited by lower ramp-shaped flanks which have the reference symbols (72), (74), (76) and (78).

Die Laufbahn (42) weist in ihrem äußeren Rand den Rollen (48) und (54) angepaßte Aufnahmen (80) und (82) auf, in der das Rollenelement (48) (Fig. 1) bzw. (54) (Fig. 2) festgelegt ist, wenn die Herzstückspitze (10) an der Flügelschiene (12) (Fig. 1) bzw. Flügelschiene (14) (Fig. 2) anliegt und verriegelt wird.The raceway (42) has in its outer edge the rollers (48) and (54) adapted Recordings (80) and (82) in which the roller element (48) (Fig. 1) and (54) (Fig. 2) is fixed when the frog tip (10) on the wing rail (12) (Fig. 1) or Wing rail (14) (Fig. 2) rests and is locked.

Wie insbesondere die Detaildarstellung der Fig. 5 verdeutlicht, ist dann, wenn die Herzstückspitze (10) an der Flügelschiene (12) verriegelt anliegt, das Rollenelement (48) in der im Schnitt kreisabschnittförmigen Aufnahme (82) eingebracht und wird in dieser durch einen horizontal verlaufenden Abschnitt (54) des Schiebers (40) gesichert, so daß ein unkontrolliertes Herausgleiten augeschlossen ist.As is particularly clear from the detailed illustration of FIG. 5, is when the Centerpiece tip (10) lies locked on the wing rail (12), the roller element (48) introduced in the section (82) in the form of a circular section and is in this secured by a horizontally extending portion (54) of the slide (40) so that an uncontrolled sliding out is excluded.

Soll nun die Herzstückspitze (10) von der Flügelschiene (12) entfernt und an die Flügelschiene (14) angelegt werden, so wird der Schieber (40) in den Ausführungsbeispielen nach rechts verschoben, wodurch einerseits das Rollenelement (45) freigegeben und andererseits dieses von der Schräge (72) erfaßt und in die kanalförmige Aufnahme (64) verschoben wird. Gleichzeitig wird der Schenkel (44) der Klammer (30) und damit die Herzstückspitze (10) angehoben. Während dieses Verschiebens gleitet die Rolle (50) aus dem Kanal (66) heraus, der erwähntermaßen geneigt verläuft, und zwar derart, daß bei an der Flügelschiene (14) anliegender Stellung der Herzstückspitze (10) diese wieder abgesenkt wird und auf den nicht dargestellten Unterlagen wie Gleitstühlen, die vor bzw. hinter den Verriegelungseinrichtungen angeordnet sind, aufliegt. Die Rolle (50) kann dann zusätzlich an einem Abschnitt (86) der Laufbahn (42) anliegen. Now the centerpiece tip (10) should be removed from the wing rail (12) and onto the wing rail (14) are created, so the slide (40) in the exemplary embodiments shifted to the right, whereby on the one hand the roller element (45) is released and on the other hand, this is gripped by the slope (72) and into the channel-shaped receptacle (64) is moved. At the same time the leg (44) of the bracket (30) and thus the Centerpiece tip (10) raised. During this shifting, the roller (50) slides out out the channel (66), which is said to be inclined, in such a way that at on the wing rail (14) in the position of the frog tip (10) again is lowered and on the documents, not shown, such as sliding chairs that are in front of or are arranged behind the locking devices, rests. The roller (50) can then additionally bear against a section (86) of the raceway (42).

Entsprechend werden die Rollen (52) und (54) -selbstverständlich im umgekehrten Sinnverschoben und festgelegt.Correspondingly, the rollers (52) and (54) are of course shifted in the opposite sense and fixed.

Das Ausführungsbeispiel der Fig. 3 unterscheidet sich von dem der Fig. 1 und 2 dahingehend, daß das Anheben der Herzstückspitze (10) nicht bzw. nicht nur über von den Verschlußklammeraufnahmen (20), (22) ausgehende Klammern (88) und (90) erfolgt, sondern iiber ein mit der Herzstückspitze (10) verbundenes und einen Vorsprung (92) aufweisendes quaderförmiges Element (94), das mit einem elastisch gelagerten Rollenelement (96) in nachstehend beschriebener Weise wechselwirkt.3 differs from that of FIGS. 1 and 2 in that the lifting of the frog tip (10) is not or not only from the clips (88) and (90) outgoing from the closure clip receptacles (20), (22) takes place, but via a protrusion connected to the frog tip (10) (92) having a cuboid element (94), which has an elastically mounted Roller element (96) interacts in the manner described below.

Abweichend von dem Ausführungsbeispiel der Fig. 1 und 2 weist ein im wesentlichen horizontal verlaufender Schenkel (98) bzw. (100) der Verschlußklammer (88) bzw. (90) nur in seinem der Herzstückspitze (10) abgewandten Endbereich (102) bzw. (104) das Rollenelement (48) bzw. (54) auf, das jedoch in zuvor beschriebener Weise mit dem Schieber (40) und der Laufbahn (42) bzw. Abschnitten dieser wechselwirkt und festgelegt wird. Insoweit wird auf die Beschreibung der Fig. 1, 2, und 5 verwiesen, wobei die Fig. 5 im eigentlichen Sinne eine Detaildarstellung der Fig. 3 darstellt.Deviating from the exemplary embodiment of FIGS. 1 and 2, an essentially has horizontally extending leg (98) or (100) of the locking clip (88) or (90) only in its end region (102) or (104) facing away from the frog tip (10) Roller element (48) or (54), but in the manner described above with the Slider (40) and the track (42) or sections of this interacts and is set. In this regard, reference is made to the description of FIGS. 1, 2 and 5, 5 in the actual sense represents a detailed representation of FIG. 3.

Der Vorsprung (52) erstreckt sich entlang der Mittelachse (106) der Herzstückspitze (10). Dabei setzt sich die dem Rollenelement (96) zugewandte Fläche (108) des quaderförmigen Blocks (94) aus äußeren konkav verlaufenden Abschnitten (110) und (112) sowie einem mittleren den Vorsprung (52) bildenden plateauartigen Abschnitt zusammen.The projection (52) extends along the central axis (106) of the frog tip (10). The surface (108) of the roller element (96) that is set cuboid blocks (94) made of outer concave sections (110) and (112) and a central plateau-like section forming the projection (52) together.

Das Rollenelement (96) ist um eine Achse (114) drehbar, die parallel zur Längsachse der Herzstückspitze (10) verläuft und in einer zwischen den Flügelschienen (12) und (14) verlaufenden Symmetrieebene (116) liegt.The roller element (96) is rotatable about an axis (114) which is parallel to the longitudinal axis the frog tip (10) runs in one between the wing rails (12) and (14) extending symmetry plane (116).

Die an dem plateauartigen Vorsprung (92) angrenzenden Bereiche der äußeren Abschnitte (108) und (110) weisen des weiteren Krümmungen auf, die in etwa gleich der Krümmung des Rollenelementes (96) ist. Hierdurch erfolgt ein rollendes Abgleiten der Fläche (108) des quaderförmigen Blocks (94) auf der Oberfläche des Rollenelementes (96), wodurch eine Verschleißreduzierung erfolgt.The areas of the outer adjoining the plateau-like projection (92) Sections (108) and (110) also have curvatures that are approximately the same the curvature of the roller element (96). This causes a rolling sliding of the Surface (108) of the cuboid block (94) on the surface of the roller element (96), which reduces wear.

Wird nun die Herzstückspitze (10) von der linken Endstellung, also von der an der Flügelschiene (12) anliegenden Stellung in die an der Flügelschiene (14) anliegenden Stellung verschoben, so werden einerseits die Verschlußklammern (58) und (90) in zuvor beschriebener Weise mittels des Schiebers (10) von links nach rechts bewegt, wobei durch das Wechselwirken des Rollenelementes (48) mit der Rampe (72) ein Anheben erfolgt, und andererseits rollt die Fläche (108) auf dem Rollenelement (96) derart ab, daß aufgrund des von der Herzstückspitze (10) weggerichteten Vorsprungs ein Anheben dieser erfolgt. Hierdurch wird sichergestellt, daß die Herzstückspitze (10) nicht auf nicht dargestellten Gleitstühlen verschoben wird, sondern beabstandet zu diesen von der linken in die rechte Endstellung bewegt wird.Now the centerpiece tip (10) from the left end position, that is from the Wing rail (12) in the position adjacent to the wing rail (14) Position shifted, on the one hand, the locking clips (58) and (90) in previously described manner by means of the slide (10) moved from left to right, wherein lifting by the interaction of the roller element (48) with the ramp (72) takes place, and on the other hand, the surface (108) rolls on the roller element (96) such that due to the projection directed away from the frog tip (10) this is done. This ensures that the frog tip (10) is not on sliding chairs shown is moved, but spaced apart from these left is moved to the right end position.

Selbstverständlich ist es nicht erforderlich, daß ein Anheben der Herzstückspitze (10) zusätzlich durch die Klammern (88) und (90) untersützt wird. Vielmehr genügt allein die Konstruktion des quaderförmigen Blockes (94) mit dem Vorsprung (92) und dessen Wechselwirken mit dem Rollenelement (96), um den Bewegungsablauf "Anheben, zur Unterlage beabstandetes Bewegen und Absenken in der gewünschten Endstellung" sicherzustellen.Of course, it is not necessary that the frog tip (10) is raised. is additionally supported by the brackets (88) and (90). Rather, it is enough alone the construction of the cuboid block (94) with the projection (92) and its Interact with the roller element (96) in order to "lift" the movement sequence Pad spaced moving and lowering in the desired end position " ensure.

Die gleiche Wirkung ergibt sich selbstverständlich auch dann, wenn von der Herzstückspitze (10) mittelbar oder unmittelbar das Rollenelement ausgeht und diesem ein den Block (94) entsprechendes Element mit dem Vorsprung zugeordnet ist, der sich entlang der Symmetrieebene (160) erstreckt.Of course, the same effect also results when from the centerpiece tip (10) indirectly or directly the role element runs out and this one Block (94) corresponding element is associated with the protrusion that extends along extends the plane of symmetry (160).

Den Fig. 6 bis 8 ist eine Wippe (118) zu entnehmen, mittels der die Herzstückspitze (10) von der einen Endstellung in die andere derart bewegt wird, daß nur in den Endstellungen ein Abstützen auf einem Gleitstuhl erfolgt, wohingegen während der Verschiebebewegung eine Beabstandung zu diesem sichergestellt ist. 6 to 8, a rocker (118) can be seen by means of which the frog tip (10) is moved from one end position to the other in such a way that only in the End positions are supported on a sliding chair, whereas during the shifting movement a distance from this is ensured.

In Fig. 6 befindet sich die Herzstückspitze (10) in der an der Flügelschiene (12) anliegenden Stellung, also der linken Endstellung, die den Fig. 1 und 4 entspricht. Dabei ruht die Herzstückspitze (10) mit ihrer Unterseite (120) auf einer Rolle (122), die von einem Balken (124) der um eine Achse (126) verschwenkbaren Wippe (118) ausgeht, und zwar vom der Flügelschiene (12) zugewandten Abschnitt.In Fig. 6 the centerpiece tip (10) is in the on the wing rail (12) adjacent position, that is the left end position, which corresponds to FIGS. 1 and 4. Here the bottom of the frog (10) rests with its underside (120) on a roller (122) that of a bar (124) which extends out from a rocker (118) pivotable about an axis (126), namely from the section facing the wing rail (12).

Mit anderen Worten befindet sich die Berührungslinie bzw. -fläche (128) zwischen Unterseite (120) der Herzstückspitze (10) und Rollenelement (122) in der Auflageebene der zwischen der bzw. den Wippen (118) angeordneten Gleitstühle bzw. Abschnitte dieser.In other words, the line of contact (128) is between Underside (120) of the frog tip (10) and roller element (122) in the support plane the sliding chairs or sections arranged between the rocker (s) (118) this.

Der Balken (124) weist ein in bezug auf die Drehachse (126) zu dem Rollenelement (128) symmetrisch angeordnetes zweites Rollenelement (130) auf, an dem die Herzstückspitze (10) bei an der Flügelschiene (12) verriegelter Endstellung mit ihrem der Flügelschiene (12) abgewandten Längsrand (132) anliegt.The beam (124) points with respect to the axis of rotation (126) to the roller element (128) symmetrically arranged second roller element (130) on which the Centerpiece tip (10) with its end position locked on the wing rail (12) the wing rail (12) faces away from the longitudinal edge (132).

Wird nun die Herzstückspitze (10) von der linken Endstellung in die rechte bewegt, so gleitet der Längsrand (132) entlang des Rollenelementes (130) und wird gleichzeitig angehoben. Hierdurch erfolgt eine sukzessive Beabstandung zu den außerhalb der Wippe (118) vorhandenen Gleitstühlen.If the centerpiece tip (10) is now moved from the left end position to the right, so the longitudinal edge (132) slides along the roller element (130) and becomes simultaneously raised. This results in a gradual spacing from those outside the seesaw (118) existing sliding chairs.

Durch das von der Herzstückspitze (10) auf die Wippe (118) einwirkende Gewicht erfolgt gleichzeitig ein Verschwenken der Wippe (118) im Uhrzeigersinn, wobei in der zwischen den Flügelschienen (12) und (14) verlaufenden Stellung (Fig. 7) der Balken (124) horizontal verläuft. In dieser Position stützt sich die Unterseite (120) der Herzstückspitze (10) auf beiden Rollenelementen (122) und (130) ab.By the weight acting on the rocker (118) from the centerpiece tip (10) the rocker (118) is pivoted clockwise at the same time, whereby in the between the wing rails (12) and (14) extending position (Fig. 7) of the bars (124) runs horizontally. In this position, the bottom (120) of the Centerpiece tip (10) on both roller elements (122) and (130).

In der rechten Endstellung, also in der an der Flügelschiene (14) anliegenden Stellung ruht die Unterseite (120) allein auf dem Rollenelement (130), wohingegen der der Flügelschiene (14) abgewandte Längsrand (134) das Rollenelement (122), das angehoben ist, berührt. In the right end position, i.e. in the position resting on the wing rail (14) the underside (120) rests solely on the roller element (130), whereas the Wing rail (14) facing away from the longitudinal edge (134) the roller element (122), which is raised is touched.

Um sicherzustellen, daß die Herzstückspitze (10) im gewünschten Umfang angehoben, zur Unterlage beabstandet bewegt und sodann wieder abgesenkt wird, sind unter Berücksichtigung der der Fig. 9 zu entnehmenden Angaben folgende Beziehungen zu wählen: S = B - 2L + 2X
