Definitions

  • the invention relates to a knitting needle for knitting machines with a needle shank provided with a needle hook and with at least one arranged on the needle top drive foot for moving the needle according to the preamble of claim 1.
  • the knitting needles are required to perform three functions: forming stitches, inserting tying loops and staying in an inactive position. These functions are achieved by the interaction of the knitting needles with needle-bed sliding knitting systems, which are used to select the needle and which drive the needles in accordance with the desired function to be performed. The one or more drive feet of the knitting needle thereby engage with different lock curves forming lock parts in the knitting systems.
  • a drive leg of the needle, or a drive member connected to the needle, projecting above the needle bed becomes selected at selected locations during the passage of the foot pressed by a cam curve in the needle bed and thus disengaged from the lock.
  • the corresponding drive foot emerges from the needle bed again and can be brought into locking engagement again.
  • the use of a structurally complex pusher lock requires in addition to the needle also the use also provided with a drive foot drive elements. In addition, there is a risk that the knitting needle may unintentionally submerge in the needle bed at a greater load in the needle longitudinal direction, resulting in malfunction.
  • the use of lifting locks is also known.
  • the drive feet of the needles or the associated drive elements are first recessed in the needle bed and are raised at predetermined points of the lock passage from the needle bed. In this way, the drive foot can be brought into engagement with different cam curves. After the lock pass, the drive foot is actively pushed back into the needle bed to disengage.
  • Such a lifting lock is for example in the EP 0 189 602 B1 described.
  • the disadvantage with the use of lifting locks is that the needle foot after the lock passage must be actively pushed back into the needle bed, which requires a greater distance between the individual knitting systems.
  • the butt must be supported at some points during the lock passage from below to prevent accidental lowering into the needle bed.
  • needles is known in which the drive foot is lowered by spring force into the needle bed.

Description

Die Erfindung betrifft eine Stricknadel für Strickmaschinen mit einem mit einem Nadelhaken versehenen Nadelschaft und mit mindestens einem an der Nadeloberseite angeordneten Antriebsfuß zur Bewegung der Nadel gemäß dem Oberbegriff von Anspruch 1.The invention relates to a knitting needle for knitting machines with a needle shank provided with a needle hook and with at least one arranged on the needle top drive foot for moving the needle according to the preamble of claim 1.

In modernen Strickmaschinen müssen mithilfe der Stricknadeln drei Funktionen erfüllt werden können: Das Bilden von Maschen, das Einlegen von Fanghenkeln und das Verharren in einer inaktiven Position. Diese Funktionen werden durch das Zusammenspiel der Stricknadeln mit über das Nadelbett hinweggleitenden Stricksystemen erreicht, mit denen die Nadelauswahl erfolgt und die die Nadeln entsprechend der gewünschten auszuführenden Funktion antreiben. Der oder die Antriebsfüße der Stricknadel gelangen dabei in Eingriff mit unterschiedlichen Schlosskurven bildenden Schlossteilen in den Stricksystemen.In modern knitting machines, the knitting needles are required to perform three functions: forming stitches, inserting tying loops and staying in an inactive position. These functions are achieved by the interaction of the knitting needles with needle-bed sliding knitting systems, which are used to select the needle and which drive the needles in accordance with the desired function to be performed. The one or more drive feet of the knitting needle thereby engage with different lock curves forming lock parts in the knitting systems.

Eine Möglichkeit, die drei unterschiedlichen Funktionen der Stricknadel sicherzustellen, besteht in der Verwendung eines so genannten Drückerschlosses. Ein über das Nadelbett heraus nach oben ragender Antriebsfuß der Nadel oder eines mit der Nadel verbundenen Antriebselements wird an ausgewählten Stellen während des Durchgangs des Fußes durch eine Schlosskurve in das Nadelbett gedrückt und somit außer Eingriff mit dem Schloss gebracht. Durch Aufheben des Druckes taucht der entsprechende Antriebsfuß aus dem Nadelbett wieder auf und kann wieder in Schlosseingriff gebracht werden. Dabei ist es auch möglich, den Antriebsfuß nur teilweise in das Nadelbett zu drücken, sodass er von anderen Schlossteilen erfasst werden kann und weitere Funktionen der Stricknadel realisiert werden können. Die Verwendung eines im Aufbau komplexen Drückerschlosses erfordert neben der Nadel zusätzlich den Einsatz ebenfalls mit einem Antriebsfuß versehener Antriebselemente. Darüber hinaus besteht die Gefahr, dass die Stricknadel bei einer stärkeren Belastung in Nadellängsrichtung ungewollt in das Nadelbett abtauchen kann, was zu Fehlfunktionen führt.One way to ensure the three different functions of the knitting needle, is the use of a so-called pusher lock. A drive leg of the needle, or a drive member connected to the needle, projecting above the needle bed becomes selected at selected locations during the passage of the foot pressed by a cam curve in the needle bed and thus disengaged from the lock. By releasing the pressure, the corresponding drive foot emerges from the needle bed again and can be brought into locking engagement again. It is also possible to press the drive foot only partially in the needle bed, so that it can be detected by other lock parts and other functions of the knitting needle can be realized. The use of a structurally complex pusher lock requires in addition to the needle also the use also provided with a drive foot drive elements. In addition, there is a risk that the knitting needle may unintentionally submerge in the needle bed at a greater load in the needle longitudinal direction, resulting in malfunction.

Neben der Verwendung von Drückerschlössern ist auch die Verwendung von Hebeschlössern bekannt. Hier sind die Antriebsfüße der Nadeln oder der zugehörigen Antriebselemente zunächst im Nadelbett versenkt und werden an vorgegebenen Stellen des Schlossdurchganges aus dem Nadelbett angehoben. Auf diese Weise kann der Antriebsfuß mit unterschiedlichen Schlosskurven in Eingriff gebracht werden. Nach dem Schlossdurchgang wird der Antriebsfuß aktiv in das Nadelbett zurückgedrückt, um außer Eingriff zu gelangen. Ein solches Hebeschloss ist beispielsweise in der EP 0 189 602 B1 beschrieben. Der Nachteil bei der Verwendung von Hebeschlössern liegt darin, dass der Nadelfuß nach dem Schlossdurchgang aktiv ins Nadelbett zurückgedrückt werden muss, was einen größeren Abstand zwischen den einzelnen Stricksystemen bedingt. Außerdem muss der Nadelfuß an einigen Stellen während des Schlossdurchgangs von unten abgestützt werden, um ein ungewolltes Absenken in das Nadelbett zu verhindern. Im Zusammenhang mit Hebeschlössern ist auch die Verwendung von Nadeln bekannt, bei denen der Antriebsfuß durch Federkraft in das Nadelbett abgesenkt wird.In addition to the use of pusher locks, the use of lifting locks is also known. Here, the drive feet of the needles or the associated drive elements are first recessed in the needle bed and are raised at predetermined points of the lock passage from the needle bed. In this way, the drive foot can be brought into engagement with different cam curves. After the lock pass, the drive foot is actively pushed back into the needle bed to disengage. Such a lifting lock is for example in the EP 0 189 602 B1 described. The disadvantage with the use of lifting locks is that the needle foot after the lock passage must be actively pushed back into the needle bed, which requires a greater distance between the individual knitting systems. In addition, the butt must be supported at some points during the lock passage from below to prevent accidental lowering into the needle bed. In connection with lifting locks also the use of needles is known in which the drive foot is lowered by spring force into the needle bed.

Allerdings müssen an diesen Nadeln zweite Antriebsfüße vorgesehen sein, die die Nadel in Kammgleiche zurückführen. Diese bekannten Nadeln sind daher relativ lang, was wiederum eine entsprechende Baugröße der Nadelbetten in Nadellängsrichtung erfordert.However, second drive feet must be provided on these needles, which return the needle in the same comb. These known needles are therefore relatively long, which in turn requires a corresponding size of the needle beds in the needle longitudinal direction.

Aus der CN 101314887 A ist ein weiteres Strickschloss bekannt, bei dem die Nadel oder ein zugehöriges Antriebselement an unterschiedlichen Stellen aktivierbar sind. Bei diesem Schloss ist neben der Nadel ein Antriebselement zwingend erforderlich. Dieses wird in eine gefedert gespannte Position gebracht und fixiert. An den vorgesehenen Stellen im Schlossdurchgang kann die Fixierung des Elements aufgehoben werden. Die Spannung des Elements bringt dann den Antriebsfuß in Eingriff mit dem Schloss. Eine verbleibende Restspannung verhindert das Abtauchen des Antriebsfußes während des Schlossdurchgangs. Allerdings kann diese Restfederkraft nur gering sein, da sie bei der nach dem Schlossdurchgang erforderlichen erneuten Fixierung des Antriebselements zusätzlich überwunden werden muss.From the CN 101314887 A Another knitting lock is known in which the needle or an associated drive element can be activated at different locations. In this lock, a drive element is required in addition to the needle. This is brought into a spring-loaded tensioned position and fixed. At the intended places in the castle passage, the fixation of the element can be canceled. The tension of the element then brings the drive foot into engagement with the lock. A residual tension prevents the drive foot from descending during the lock pass. However, this residual spring force can only be small, since it must be additionally overcome in the required after the lock passage renewed fixation of the drive element.

Schließlich ist aus der EP 0 569 065 A1 eine Stricknadel bekannt, die nur einen Antriebsfuß aufweist, wobei jedoch der gesamte Nadelschaft als ein biegeweiches Element ausgeführt ist. Durch diese Ausgestaltung ist die Nadel jedoch anfällig für Verdrehungen bei seitlicher Belastung, und außerdem kann es auch bei dieser Nadel zu einem unbeabsichtigten Absenken des Antriebsfußes in das Nadelbett kommen.Finally, out of the EP 0 569 065 A1 a knitting needle is known which has only one drive foot, but wherein the entire needle shaft is designed as a flexible element. By virtue of this configuration, however, the needle is susceptible to twisting in the event of lateral loading, and, moreover, even in the case of this needle, an unintentional lowering of the drive foot into the needle bed can occur.

Aus der CN 101570914 A ist eine Zungennadel bekannt, welche mit einem separaten Auswahl- und Antriebselement formschlüssig verbunden ist. Das federnde Element des Antriebselements stützt sich nicht im oder am Nadelschaft oder sonstigen Elementen der Nadel ab.From the CN 101570914 A a latch needle is known, which is positively connected to a separate selection and drive element. The resilient element of the drive element is not supported in or on the needle shaft or other elements of the needle.

Aus der DE 195 41 407 A1 ist eine Steuerplatine bekannt, welche zur Auswahl und Steuerung Maschen bildender Bewegungen von Stricknadeln in einer Rundstrickmaschine dient. Die Platine weist einen starr ausgeführten Steuerschenkel sowie einen darunterliegenden Federschenkel auf. Soll die Platine nicht zur Bewegungseinleitung in die Stricknadel ausgewählt werden, so drückt das Schlossteil den Steuerschenkel durch Kontakt mit der Längskante eines Fußes in Richtung Nutgrund, wodurch eine Fläche des Auswahlfußes an einem Permanentmagneten der Steuermagnetanordnung gedrückt wird. Der Fuß bleibt dann bis zur Aufhebung der Magnetkraft am Magneten haften.From the DE 195 41 407 A1 a control board is known, which serves for selecting and controlling mesh forming movements of knitting needles in a circular knitting machine. The board has a rigid running control leg and an underlying spring leg. If the board is not selected for movement initiation in the knitting needle, the lock member pushes the control leg by contact with the longitudinal edge of a foot towards the groove base, whereby a surface of the selection foot is pressed against a permanent magnet of the control magnet assembly. The foot will then adhere to the magnet until the magnetic force is removed.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Stricknadel für Strickmaschinen bereitzustellen, die einfach aufgebaut ist und ohne zusätzliche Antriebselemente im Nadelbett von einem Stricksystem zur wahlweisen Durchführung einer der drei Funktionen Maschen bilden, Fang einlegen oder inaktiv verharren antreibbar ist.The present invention has for its object to provide a knitting needle for knitting machines, which is simple in construction and form without additional drive elements in the needle bed of a knitting system for selectively performing one of the three functions mesh, insert catch or remain inactive can be driven.

Die Aufgabe wird gelöst mit einer Stricknadel für Strickmaschinen mit einem mit einem Nadelhaken versehenen Nadelschaft und mit mindestens einem an ihrer Oberseite angeordneten Antriebsfuß zur Bewegung der Nadel mit den Merkmalen des Anspruchs 1.The object is achieved with a knitting needle for knitting machines with a needle shaft provided with a needle hook and with at least one drive foot arranged on its top for moving the needle with the features of claim 1.

Der Nadelschaft dieser Nadel kann zumindest überwiegend aus einem biegesteifen Material gefertigt werden und dadurch die notwendige Stabilität aufweisen. Eine solche Nadel kann besonders einfach hergestellt werden. Sie kann eine geringe Masse aufweisen und dadurch schnell bewegbar sein. Der zumindest eine Anschlag sorgt dafür, dass der Antriebsfuß eine definierte Endposition einnehmen kann, und dient bei Nadeln mit einem federnden Abschnitt des Nadelschafts gleichzeitig zur Stabilisierung des federnden Abschnitts. Wenn nur ein Antriebsfuß vorgesehen ist, ist die Nadel einfach im Aufbau und weist eine relativ geringe Länge auf.The needle shaft of this needle can be made at least predominantly of a rigid material and thereby have the necessary stability. Such a needle can be produced particularly easily. It can have a low mass and thus be quickly movable. The at least one stop ensures that the drive foot can assume a defined end position and at the same time serves for stabilizing the resilient section in needles with a resilient portion of the needle shaft. If only one drive foot is provided, the needle is simple in construction and has a relatively short length.

Wenn der Antriebsfuß entgegen einer Federkraft bewegbar ist, kann eine der Endstellungen des Antriebsfußes durch die in der Nadel selbst erzeugte Federkraft eingenommen werden. Der Antriebsfuß muss nur in eine der Bewegungsrichtungen aktiv angetrieben werden. Daher sind nur wenige Antriebselemente für die Stricknadel nötig. Dies ermöglicht einen relativ schmalen Aufbau der Nadelbetten in Nadellängsrichtung. Auch die Strickschlösser zum Antrieb der Stricknadel können einen vergleichsweise einfachen Aufbau haben. Es ist nur ein Antriebsfuß zu beaufschlagen. Eine der Bewegungsrichtungen des Antriebsfußes quer zur Nadellängsrichtung wird außerdem durch die Federkraft übernommen, muss also nicht aktiv ausgelöst werden. Es muss kein Drücker- oder Hebeschloss eingesetzt werden.If the drive foot is movable against a spring force, one of the end positions of the drive foot can be assumed by the spring force generated in the needle itself. The drive foot must only be actively driven in one of the directions of movement. Therefore, only a few drive elements for the knitting needle are needed. This allows a relatively narrow construction of the needle beds in the needle longitudinal direction. The knitting locks for driving the knitting needle can also have a comparatively simple construction. There is only one drive foot to apply. A The directions of movement of the drive foot transversely to the needle longitudinal direction is also taken over by the spring force, so it must not be triggered active. There is no need to use a pusher or lift lock.

Wenn der mindestens eine Anschlag an einem Schenkel des Nadelschafts angeordnet ist, ergibt sich ein einfacher, massearmer Aufbau der Nadel.If the at least one stop is arranged on a leg of the needle shaft, the result is a simple, low-mass construction of the needle.

Bei einer bevorzugten Ausgestaltung kann der Antriebsfuß in seiner äußersten abgesenkten Stellung nicht über den Nadelschaft bzw. das Nadelbett nach oben ragen. In dieser Stellung wird die Nadel also nicht von Schlossteilen erfasst. Andererseits kann der Antriebsfuß mindestens in seiner äußersten angehobenen Position über den Nadelschaft bzw. das Nadelbett nach oben ragen, sodass er von Schlossteilen erfassbar ist. Außerdem ist es möglich, den Antriebsfuß in Zwischenstellungen zwischen seiner äußersten angehobenen und seiner äußersten abgesenkten Position zu bringen, in denen er ebenfalls über den Nadelschaft nach oben ragt.In a preferred embodiment, the drive foot in its outermost lowered position does not protrude above the needle shaft or the needle bed upwards. In this position, the needle is therefore not covered by lock parts. On the other hand, the drive foot can protrude above the needle shaft or needle bed at least in its outermost raised position, so that it can be detected by lock parts. In addition, it is possible to bring the drive foot in intermediate positions between its outermost raised and its outermost lowered position in which it also projects above the needle shaft upwards.

Der Aufbau der Nadel kann unterschiedlich gestaltet werden. Bei einer ersten Variante kann der Antriebsfuß an einem federnden Abschnitt des Nadelschafts angeordnet sein. Die Nadel ist somit (abgesehen von einer Zunge) einteilig ausgebildet. Da der Nadelschaft außerhalb des federnden Bereiches biegesteif ausgeführt werden kann, ist die erforderliche mechanische Stabilität der Nadel gewährleistet.The structure of the needle can be designed differently. In a first variant of the drive foot can be arranged on a resilient portion of the needle shaft. The needle is thus integrally formed (apart from a tongue). Since the needle shaft outside the resilient region can be made rigid, the required mechanical stability of the needle is guaranteed.

Bei einer anderen Ausgestaltung kann der Antriebsfuß an einem gelenkig mit dem Nadelschaft verbundenen Schwenkelement gelagert sein, wobei das Schwenkelement in mindestens einer Richtung entgegen einer Federkraft gegenüber dem Nadelschaft verschwenkbar ist. Auch diese zweiteilige Ausgestaltung der Stricknadel ermöglicht die gewünschten Verstellmöglichkeiten des Antriebsfußes. Die Federkraft kann dabei von einem federnden Abschnitt des Nadelschafts oder des Schwenkelements erzeugt werden.In another embodiment, the drive foot may be mounted on a pivotally connected to the needle shaft pivot member, wherein the pivot member is pivotable in at least one direction against a spring force relative to the needle shaft. Also, this two-part design of the knitting needle allows the desired Adjustment possibilities of the drive foot. The spring force can be generated by a resilient portion of the needle shaft or the pivot member.

Wenn der mindestens eine Anschlag oberhalb des federnden Abschnitts angeordnet ist, kann der Antriebsfuß gegen eine Federkraft aus einer unteren entspannten Position in mindestens eine angehobene Position gebracht werden, wobei der Anschlag die Bewegung begrenzt. Eine Bewegung in umgekehrter Richtung kann durch das Nadelbett begrenzt werden. Der federnde Abschnitt kann an einer, insbesondere beliebigen, Höhe zwischen Nadelgrund und der Unterkante des Anschlags angeordnet, insbesondere mit dem (übrigen) Nadelschaft verbunden sein. Die Geometrie des federnden Abschnitts ist je nach Anwendung frei wählbar.When the at least one stop is located above the resilient portion, the drive foot may be brought against a spring force from a lower relaxed position to at least one raised position, the stop limiting movement. A movement in the opposite direction can be limited by the needle bed. The resilient portion may be arranged at one, in particular, any height between the needle bottom and the lower edge of the stop, in particular to be connected to the (remaining) needle shank. The geometry of the resilient section is freely selectable depending on the application.

Nachfolgend werden verschiedene Ausführungsbeispiele erfindungsgemäßer Stricknadeln anhand der Zeichnung näher beschrieben.Various embodiments of knitting needles according to the invention will be described in more detail below with reference to the drawing.

Above the resilient portion 2, the needle shaft 1 on a leg 4, which has a stop 5 at its end remote from the needle shaft 1 end.

Der Schenkel 4 erstreckt sich im Wesentlichen in die gleiche Richtung wie der federnde Abschnitt 2. Der Schenkel 4 ist, wie alle Teile der Stricknadel 10 mit Ausnahme des federnden Abschnitts 2, biegesteif ausgeführt.The leg 4 extends substantially in the same direction as the resilient portion 2. The leg 4 is, like all parts of the knitting needle 10 with the exception of the resilient portion 2, rigid.

Der Anschlag 5 dient zur Begrenzung der Bewegung des Antriebsfußes 3 nach oben, wodurch der Antriebsfuß 3 eine definierte obere Endposition einnehmen kann.The stop 5 serves to limit the movement of the drive foot 3 upwards, whereby the drive foot 3 can assume a defined upper end position.

In der Fig. 1 a ist der federnde Abschnitt 2 der Stricknadel 10 in seinem entspannten Zustand gezeigt. Der Antriebsfuß 3 befindet sich so in einer abgesenkten Position. In dieser Position ist der Antriebsfuß 3 im Nadelbett versenkt, ragt also nicht über den Nadelschaft 1 und die Abdeckschiene 110 hinaus und kann so nicht durch hier nicht gezeigte Schlossteile eines Strickschlosses erfasst werden.In the Fig. 1 a, the resilient portion 2 of the knitting needle 10 is shown in its relaxed state. The drive foot 3 is thus in a lowered position. In this position, the drive foot 3 is sunk in the needle bed, so does not protrude beyond the needle shaft 1 and the cover rail 110 and can not be detected by not shown here lock parts of a knitting castle.

Durch Druck von unten auf den Antriebsfuß 3 kann dieser in eine der Fig. 1b entsprechende Position gebracht werden.By pressure from below on the drive foot 3, this can in one of Fig. 1b appropriate position to be brought.

Fig. 1b zeigt die Stricknadel 10 aus Fig. 1a in einem Zustand, in welchem der Antriebsfuß 3 durch Druck von unten mittels einer Kraft F entgegen der Federkraft des federnden Abschnitts 2 in eine angehobene Position gebracht wurde. Fig. 1b shows the knitting needle 10 from Fig. 1a In a state in which the drive foot 3 has been brought by pressure from below by means of a force F against the spring force of the resilient portion 2 in a raised position.

In dieser Position ragt der Antriebsfuß 3 über den Nadelschaft 1 und die Abdeckschiene 110 hinaus und kann so von hier nicht gezeigten Schlossteilen eines Strickschlosses erfasst werden.In this position, the drive foot 3 protrudes beyond the needle shaft 1 and the cover rail 110 and can thus be detected by lock parts, not shown here, of a knitting lock.

Der federnde Abschnitt 2 kommt in dieser Position zur Anlage an den Anschlag 5 des Schenkels 4. Dadurch kann der Antriebsfuß 3 eine definierte obere Endposition einnehmen. Gleichzeitig bietet dieser Anschlag eine Möglichkeit zur Stabilisierung des federnden Abschnitts 2.The resilient portion 2 comes in this position to rest against the stop 5 of the leg 4. This allows the drive foot 3 occupy a defined upper end position. At the same time, this stop offers a possibility for stabilizing the resilient section 2.

Sobald die Einwirkung der Kraft F endet, senkt sich der federnde Abschnitt 2 mit dem Antriebsfuß 3 wieder in die in Fig. 1a gezeigte Position ab. Das Nadelbett 100 kann als Anschlag für die untere Position des Antriebsfußes 3 dienen. Der federnde Abschnitt 2 ist unterhalb des Schenkels 4, insbesondere zwischen Nadelbett und Schenkel 4 bzw. Anschlag 5, angeordnet. Mit dem übrigen Nadelschaft 1 ist der federnde Abschnitt 2 unterhalb des Schenkels 4 verbunden. Die Nadel 10 ist, abgesehen von der Zunge 8, einteilig bzw. einstückig ausgebildet. Es versteht sich, dass der federnde Abschnitt 2 in umgekehrter Richtung vorgespannt sein kann, sodass der Antriebsfuß im entspannten Zustand in einer oberen Position ist und der federnde Abschnitt 2 am Anschlag 5 anliegt. Der Antriebsfuß 3 wird dann entgegen der Federkraft nach unten bewegt und kann in einer unteren Endposition am Nadelbett 100 anliegen.As soon as the action of the force F ends, the resilient portion 2 lowers with the drive foot 3 back into the in Fig. 1a shown position. The needle bed 100 can serve as a stop for the lower position of the drive foot 3. The resilient portion 2 is below the leg 4, in particular between the needle bed and leg 4 or stop 5, respectively. With the rest of the needle shaft 1, the resilient portion 2 is connected below the leg 4. The needle 10 is, apart from the tongue 8, formed in one piece or in one piece. It is understood that the resilient portion 2 may be biased in the reverse direction, so that the drive foot in the relaxed state in an upper position and the resilient portion 2 rests against the stop 5. The drive foot 3 is then moved counter to the spring force down and can rest in a lower end position on the needle bed 100.

Die Fig. 2a, 2b zeigen ein Beispiel einer zweiteiligen Stricknadel 20, bei der der Antriebsfuß 23 an einem Schwenkelement 27 angeordnet ist. Das Schwenkelement 27 ist an einer Gelenkstelle 29 des Nadelschafts 21 drehbar gelagert. Bei dieser Nadel ist der gesamte Nadelschaft 21 biegesteif ausgebildet. Die Federkraft wird von einem federnden Abschnitt 22 des Schwenkelements 27 erzeugt, das zwischen den beiden Schenkeln 24 und 30 des Nadelschafts 21 eingeführt ist und sich zwischen diesen Schenkeln 24, 30 abstützt. In der in Fig. 2a gezeigten entspannten Position des Federelements 22 befindet sich der Antriebsfuß 23 in seiner angehobenen Position. Dagegen zeigt Fig. 2b den Antriebsfuß 23 in seiner abgesenkten Position. Das Schwenkelement 27 ist nach unten verschwenkt. Das Federelement 22 hat sich nach oben gewölbt und ist somit vorgespannt, um den Antriebsfuß 23 nach der Beendigung einer Krafteinwirkung auf ihn wieder in seine angehobene Ausgangsposition bringen zu können.The Fig. 2a, 2b show an example of a two-piece knitting needle 20, in which the drive foot 23 is arranged on a pivoting element 27. The Pivoting element 27 is rotatably mounted at a hinge point 29 of the needle shaft 21. In this needle, the entire needle shaft 21 is formed rigid. The spring force is generated by a resilient portion 22 of the pivot member 27 which is inserted between the two legs 24 and 30 of the needle shank 21 and is supported between these legs 24, 30. In the in Fig. 2a shown relaxed position of the spring element 22 is the drive foot 23 in its raised position. On the other hand shows Fig. 2b the drive foot 23 in its lowered position. The pivoting element 27 is pivoted downwards. The spring element 22 has arched upward and is thus biased to bring the drive foot 23 after the termination of a force on him back to its raised starting position.

Der eigensteife Schenkel 24 weist einen Anschlag 25 für das Schwenkelement 27 mit dem Antriebsfuß 23 auf. In dem in Fig. 1a gezeigten entspannten Zustand ist der am Schwenkelement 27 angeordnete federnde Abschnitt 22 nach unten durchgebogen, sodass das Schwenkelement 27 am Anschlag 25 anliegt und der Antriebsfuß 23 aus dem Nadelbett 100 heraus angehoben ist. Durch Druck auf den Antriebsfuß 23 kann dieser abgesenkt werden, wie Fig. 2b zeigt. Das Schwenkelement 27 verschwenkt nach unten bis zur Anlage an dem Nadelbett 100. Das Federelement 22 wird nach oben durchgebogen, um den Antriebsfuß 23 nach Beendigung der Krafteinwirkung auf ihn wieder in seine angehobene Ausgangsposition bringen zu können.The intrinsically stiff leg 24 has a stop 25 for the pivoting element 27 with the drive foot 23. In the in Fig. 1a shown relaxed state of the pivot member 27 arranged resilient portion 22 is bent downwards so that the pivot member 27 rests against the stop 25 and the drive foot 23 is lifted out of the needle bed 100 out. By pressure on the drive 23, this can be lowered, as Fig. 2b shows. The pivot member 27 pivots down until it touches the needle bed 100. The spring element 22 is bent upward to bring the drive foot 23 after completion of the force on him back to its raised starting position.

Die entspannte Stellung des Federelements 22 könnte jedoch auch die nach oben durchgebogene Stellung sein, in der der Antriebsfuß 23 in einer abgesenkten Position ist. Durch Druck von unten auf den Fuß 23 kann dieser in die in Fig. 2a gezeigte Position gebracht werden.However, the relaxed position of the spring element 22 could also be the upwardly bent position in which the drive foot 23 is in a lowered position. By pressure from below on the foot 23, this can be in the in Fig. 2a shown position.

Bei den dargestellten Nadeln 10, 20 handelt es sich um Zungennadeln. Es versteht sich, dass die Nadeln auch als Schiebernadeln ausgebildet sein könnten.The illustrated needles 10, 20 are latch needles. It is understood that the needles could also be designed as a slider needles.
