Description

Die Erfindung betrifft eine Schiebernadel für Strickmaschinen.The invention relates to a needle for knitting machines.

Es sind Schiebernadeln mit geteiltem Schieber bekannt. Solche Schieber weisen mindestens zwei Schenkel auf, die in einem Schieberkanal laufen und durch einen Mittelsteg auf Abstand gehalten sind.There are known sliding needles with split slider. Such slides have at least two legs which run in a slide channel and are held by a central web at a distance.

Aus der EP 1 229 159 ist eine solche Schiebernadel mit einem Mittelsteg bekannt. Der Mittelsteg ist dort einstückiger Bestandteil des Nadelkörpers. Die Verwirklichung dieses Konzepts erfordert einen hohen Fertigungsaufwand und führt zu einer steifen Lagerung des Mittelstegs.From the EP 1 229 159 is such a needle with a center bar known. The center bar is there integral part of the needle body. The realization of this concept requires a high production cost and leads to a rigid storage of the central web.

Aus der EP 1 424 417 B1 ist ebenfalls eine Schiebernadel mit einem Mittelsteg bekannt. Dieser ist als gesondertes Zwischenwandelement ausgebildet, das nachträglich in den Nadelgrundkörper eingesetzt und mit diesem unlösbar verbunden wird. Der Schieberkanal dieser Schiebernadel wird von zwei Seitenwänden und einem Boden begrenzt. Eine sich sowohl durch den Boden wie auch teilweise durch eine Seitenwand erstreckende größere Öffnung nimmt einen Fortsatz des Zwischenwandelements auf. Durch die Öffnung ist der Fortsatz von der Seite her zugänglich. Er wird mit dem Nadelkörper verstemmt, so dass eine dauerhafte unbewegliche Verbindung gegeben ist. Allerdings ist der Herstellungsaufwand beträchtlich. Die entstehende Nadel weist durch die bezüglich der Mittelebene asymmetrische Anbringung der genannten Öffnung eine erhebliche Schwächung auf. Unterliegt die Nadel beispielsweise durch den Zug des an ihr hängenden Gestricks einer Biegebelastung, kann sich der Mittelsteg lösen. Außerdem ist es relativ schwierig mit diesem Konzept eine ausreichende Genauigkeit insbesondere hinsichtlich der Positionierung des Zwischenwandelements zu erzielen.From the EP 1 424 417 B1 is also known a needle with a central bar. This is designed as a separate intermediate wall element, which is subsequently used in the needle body and connected to this inseparable. The slide channel of this needle is limited by two side walls and a bottom. A larger opening extending through both the floor and partially through a side wall receives an extension of the intermediate wall element. Through the opening of the extension is accessible from the side. He is caulked with the needle body, so that a permanent immobile connection is given. However, the production cost is considerable. The resulting needle has due to the asymmetrical with respect to the center plane attachment of said opening to a significant weakening. subject the needle, for example, by the train of hanging on her knit a bending load, the center bar can solve. In addition, it is relatively difficult to achieve sufficient accuracy with this concept, in particular with regard to the positioning of the intermediate wall element.

Löst sich von der Nadel irgendein Element, wie beispielsweise das Zwischenwandelement, und gelangt es dann in die Strickmaschine, kann das sich unkontrolliert bewegende Zwischenwandelement zu erheblichen Beschädigungen der Strickmaschine führen.If any element, such as the intermediate wall element, loosens from the needle and then enters the knitting machine, the uncontrollably moving intermediate wall element can lead to considerable damage to the knitting machine.

Davon ausgehend ist es Aufgabe der Erfindung, ein verbessertes Konzept für Schiebernadeln mit Mittelstegteil anzugeben.On this basis, it is an object of the invention to provide an improved concept for slider needles with central web part.

Diese Aufgabe wird mit der Schiebernadel nach Anspruch 1 gelöst:

  • Die erfindungsgemäße Schiebernadel weist einen Nadelkörper auf, bei dem der Boden des Schieberkanals mit mindestens einer Öffnung versehen ist. Durch diese erstreckt sich ein Fußfortsatz eines in dem Schieberkanal angeordneten Zwischenwandelements. Der Fußfortsatz untergreift den Boden des Schieberkanals und sichert auf diese Weise das Zwischenwandelement formschlüssig in dem Schieberkanal. Indem der Fußfortsatz den Boden untergreift ist sichergestellt, dass sich das Zwischenwandelement nicht aus der Schiebernadel lösen und unkontrolliert in der Strickmaschine bewegen kann.
This object is achieved with the slider needle according to claim 1:
  • The slider needle according to the invention has a needle body, wherein the bottom of the slide channel is provided with at least one opening. Through this extends a foot extension of an arranged in the slide channel intermediate wall element. The foot extension engages under the bottom of the slide channel and thus secures the intermediate wall element form fit in the slide channel. By the foot extension engages under the ground is ensured that the intermediate wall element can not solve the needle and move uncontrolled in the knitting machine.

Die Öffnung in dem Boden des Schieberkanals ist vorzugsweise schlitzartig ausgebildet. Sie erstreckt sich vorzugsweise in Schieberkanallängsrichtung. In einer bevorzugten Ausführungsform hält die Öffnung zu beiden Seitenwänden jeweils einen Abstand ein. Mit anderen Worten, zu beiden Seiten der vorzugsweise schlitzartigen Öffnung sind streifenförmige Bodenbereiche vorhanden, die einerseits an eine jeweilige Seitenwand und andererseits an die Öffnung grenzen. Diese beiden streifenförmigen Bodenbereiche liegen vorzugsweise in einer gemeinsamen Ebene. Die Bodenbereiche bilden vorzugsweise Gleitflächen für die beiden Schenkel des Schiebers. Anders ausgedrückt, der z.B., länglich ovale Schlitz wird entlang seines gesamten Umfangs von dem Boden umgeben.The opening in the bottom of the slide channel is preferably formed slit-like. It preferably extends in Schieberkanallängsrichtung. In a preferred embodiment, the opening holds on both side walls each one at a distance. In other words, on both sides of the preferably slot-like opening strip-shaped bottom areas are present, which border on the one hand to a respective side wall and on the other hand to the opening. These two strip-shaped bottom regions are preferably located in a common plane. The bottom regions preferably form sliding surfaces for the two legs of the slider. In other words, the elongated oval slot, for example, is surrounded by the floor along its entire circumference.

Das Zwischenwandelement weist im Wesentlichen eine rechteckige Form auf und ist als dünnes ebenes Flachteil ausgebildet. Es weist vorzugsweise einen Federteil auf, der von dem Fußfortsatz mittig parallel zwischen den Seitenwänden gehalten ist. Der Fußfortsatz ist vorzugsweise ein Flachteil, das durch die vorzugsweise schlitzartige Öffnung mittig positioniert ist, so dass das Federteil dadurch seine präzise Ausrichtung parallel zu den Seitenwänden erhält. Vorzugsweise ist das Zwischenwandelement generell mit etwas Längsspiel und/oder mit etwas Seitenspiel gehalten.The intermediate wall element has a substantially rectangular shape and is formed as a thin planar flat part. It preferably has a spring part which is held centrally by the foot extension parallel between the side walls. The foot extension is preferably a flat member centrally positioned through the preferably slot-like opening so that the spring member thereby maintains its precise alignment parallel to the side walls. Preferably, the intermediate wall element is generally held with some longitudinal play and / or with some side play.

Der Fußfortsatz ist an dem Boden vorzugsweise formschlüssig verankert, wobei der Formschluss sowohl durch dauerhaftes Verformen, beispielsweise Verbiegen oder auch durch federnde Wirkung des Fußfortsatzes oder Abschnitte desselben erreicht werden kann. Bei einer bevorzugten Ausführungsform sind Enden des Fußfortsatzes in Querrichtung gebogen. Das Zwischenwandelement kann dadurch ortsfest oder auch mit geringem Spiel gehalten.sein. Das Spiel kann ein Längsspiel sein, das in Schieberbewegungsrichtung vorhanden ist. Zusätzlich oder alternativ kann ein gewisses Querspiel vorhanden sein, so dass das Zwischenwandelement seitlich etwas beweglich ist. Auf diese Weise kann ein unerwünschtes Klemmen des Schiebers sicher ausgeschlossen werden.The foot extension is preferably anchored positively on the ground, wherein the positive engagement can be achieved both by permanent deformation, such as bending or by the resilient action of the foot extension or sections thereof. In a preferred embodiment, ends of the foot extension are bent transversely. The intermediate wall element can thereby be fixed or held with little play. The game may be a longitudinal game that exists in the slider movement direction. Additionally or alternatively, a certain transverse play may be present, so that the intermediate wall element is slightly laterally movable. In this way, unwanted clamping of the slide can be safely excluded.

Es können auch Abschnitte des Fußfortsatzes in Längsrichtung unter den Boden gebogen sein. Auch hier ist es wiederum möglich das Zwischenwandelement mit einem gewissen Spiel zu halten. Das Spiel kann in Schieberkanallängsrichtung, d.h. in Schieberbewegungsrichtung wie auch quer dazu gegeben sein.Also, portions of the foot extension may be bent longitudinally below the floor. Again, it is again possible to keep the partition element with a certain amount of play. The play can take place in the slider channel longitudinal direction, i. in Schieberbewegungsrichtung as well as be given transversely thereto.

Es ist auch möglich, das Zwischenwandelement federnd beispielsweise durch Rastmittel an dem Nadelkörper zu lagern. Dazu können an dem Fußfortsatz oder alternativ an dem Federteil elastische Elemente oder federnd gelagerte Elemente vorgesehen sein. Solche federnden Abschnitte können beispielsweise federnde Zungen sein, die sich kostengünstig durch anbringen entsprechender Einschnitte an dem Zwischenwandelement herstellen lassen.It is also possible to support the intermediate wall element resiliently, for example by latching means on the needle body. For this purpose, elastic elements or resiliently mounted elements can be provided on the foot extension or alternatively on the spring part. Such resilient portions may be, for example, resilient tongues, which can be inexpensively produced by attaching corresponding cuts on the intermediate wall element.

An dem Nadelrücken ist vorzugsweise eine Vertiefung vorgesehen, die insbesondere umgebogene Abschnitte des Fußfortsatzes aufnehmen kann. Dadurch wird sichergestellt, dass keinerlei Abschnitte des Fußfortsatzes über den Nadelrücken hinaus ragen.At the needle back a recess is preferably provided, which can accommodate in particular bent portions of the foot process. This ensures that no sections of the foot process protrude beyond the needle back.

Zusätzlich zur formschlüssigen Verbindung des Zwischenwandelements mit dem Nadelkörper kann die formschlüssige Verbindung durch ein stoffschlüssiges Mittel wie beispielsweise ein Klebstoff oder ein Sicherungslack oder ein Schweißstelle gesichert sein.In addition to the positive connection of the intermediate wall element with the needle body, the positive connection can be secured by a cohesive means such as an adhesive or a security lacquer or a weld.

Wie aus Figur 2 ersichtlich, ist in dem Schieberkanal 7 zwischen den beiden Seitenwänden 5, 6 und zwischen den Lamellen 9, 10 ein Zwischenwandelement 15 angeordnet, dessen Dicke zweckentsprechend gewählt ist und beispielsweise der Dicke der Lamellen 9, 10 und/oder der Seitenwände 5, 6 entsprechen kann. Das Zwischenwandelement 15 ist vorzugsweise ein flaches, ebenes Blechteil, das die beiden Lamellen 9, 10 voneinander entfernt hält. Es kann an jeder geeigneten Stelle des Schieberkanals 7 angeordnet sein, beispielsweise in unmittelbarer Nachbarschaft des Hakens 3 wie in Figur 2 und 3 veranschaulicht oder auch in etwas größerem Abstand zu dem Haken 3, beispielsweise an einer Stelle 16, wie in Figur 1 angedeutet.How out FIG. 2 can be seen, in the slide channel 7 between the two side walls 5, 6 and between the slats 9, 10, an intermediate wall member 15 is arranged, whose thickness is chosen appropriately and, for example, the thickness of the slats 9, 10 and / or the side walls 5, 6 correspond , The intermediate wall element 15 is preferably a flat, flat sheet metal part, which holds the two blades 9, 10 away from each other. It can be arranged at any suitable point of the slide channel 7, for example in the immediate vicinity of the hook 3 as in FIGS. 2 and 3 illustrated or at a slightly greater distance from the hook 3, for example at a point 16, as in FIG. 1 indicated.

Figur 4 veranschaulicht den Schieberkanal anhand eines Nadelquerschnitts entlang der Linie IV-IV gemäß Figur 3. Der Schieberkanal 7 wird von den beiden Seitenwänden 5, 6 und einem Boden 17 begrenzt, der den Schieberkanal 7 nach unten, d.h. zu dem Nadelrücken 18 hin abgrenzt. Der Boden 17 ist von einer Öffnung 19 durchsetzt, die zu dem Nadelrücken 18 führt. Die Öffnung 19 kann jede geeignete Form haben. Zum Beispiel ist sie schlitzförmig. Sie erstreckt sich dann als Schlitz vorzugsweise in der Längsrichtung des Schieberkanals, d.h. parallel zu den Seitenwänden 5, 6 und den Lamellen 9, 10. FIG. 4 illustrates the slide channel according to a needle cross-section along the line IV-IV according to FIG. 3 , The slide channel 7 is bounded by the two side walls 5, 6 and a bottom 17, the slide channel 7 after below, ie delimited to the needle back 18 out. The bottom 17 is penetrated by an opening 19 which leads to the needle back 18. The opening 19 may have any suitable shape. For example, it is slit-shaped. It then extends as a slot preferably in the longitudinal direction of the slide channel, ie parallel to the side walls 5, 6 and the slats 9, 10th

Die schlitzartige Öffnung 19 ist vorzugsweise mittig in dem Schieberkanal 7 angeordnet. Sie ist vorzugsweise schmaler als derselbe. Somit sind zu beiden Seiten der Öffnung 19 streifenförmige Bodenabschnitte 20, 21 ausgebildet, die jeweils außen an die Innenflächen 22, 23 der Seitenwände 5, 6 und innen an die schlitzartige Öffnung 19 grenzen. Zu dem Nadelrücken 18 hin mündet die Öffnung 19 vorzugsweise in einer Vertiefung 24, die sich zum Beispiel über die gesamte Breite des Nadelkörpers 2 und mindestens über die gesamte Länge der als Schlitz ausgebildeten Öffnung 19 erstreckt.The slot-like opening 19 is preferably arranged centrally in the slide channel 7. It is preferably narrower than the same. Thus, on both sides of the opening 19 strip-shaped bottom portions 20, 21 are formed, each of which adjoin the outside of the inner surfaces 22, 23 of the side walls 5, 6 and the inside of the slot-like opening 19. Toward the needle back 18, the opening 19 preferably opens into a recess 24 which, for example, extends over the entire width of the needle body 2 and at least over the entire length of the opening 19 formed as a slot.

Das Zwischenwandelement 15 weist einen Federteil 25 auf, der sich zwischen die Lamellen 9, 10 erstreckt, sowie mindestens einen Fußfortsatz 26, der durch den durch die Öffnung 19 gebildeten Schlitz ragt. Der Fußfortsatz 26 kann mit geringem Spiel in die Öffnung 19 des Bodens 17 reichen. Dadurch führt der Fußfortsatz 26 das Zwischenwandelement 15 in seitlicher Richtung, da es an den aufeinander zu weisenden Innenflächen der Öffnung 19 des Bodens 17 anliegen kann. Das Zwischenwandelement 15 ist vorzugsweise ein Blechteil mit einheitlicher Blechdicke. Wie Figur 4 veranschaulicht, können Abschnitte 27, 28 des Fußfortsatzes 26 seitlich, d.h. in Nadelquerrichtung in unterschiedlichen Richtungen seitlich weg gebogen sein, wodurch diese Abschnitte 27, 28 des Fußfortsatzes 26 den Boden 17 untergreifen. Die Verhältnisse sind in Figur 5 nochmals aus anderer Blickrichtung dargestellt. Wie ersichtlich, sind die seitlich weg gebogenen Abschnitte 27, 28 des Fußfortsatzes 26 vollständig von der Vertiefung 24 aufgenommen. Sie ragen deshalb nicht über den Nadelrücken 18 hinaus.The intermediate wall element 15 has a spring part 25 which extends between the slats 9, 10, and at least one foot extension 26 which projects through the slot formed by the opening 19. The foot extension 26 may reach into the opening 19 of the bottom 17 with little play. As a result, the foot extension 26 guides the intermediate wall element 15 in the lateral direction, since it can rest against the inner surfaces of the opening 19 of the base 17 facing one another. The intermediate wall element 15 is preferably a sheet metal part with a uniform sheet thickness. As FIG. 4 1, sections 27, 28 of the foot extension 26 can be laterally bent in different directions in the transverse direction of the needle, as a result of which these sections 27, 28 of the foot extension 26 engage under the floor 17. The conditions are in FIG. 5 again from another Viewing direction shown. As can be seen, the laterally bent portions 27, 28 of the foot extension 26 are completely received by the recess 24. They therefore do not protrude beyond the needle back 18.

Das Zwischenwandelement 15 ist durch den Fußfortsatz 26 und die den Boden 17 untergreifenden Abschnitte 27, 28 formschlüssig positioniert und mittig gehalten. Das Zwischenwandelement 15 kann jedoch, wie insbesondere Figur 5 andeutet, ein gewisses Längsspiel haben. Außerdem kann es ein gewisses seitliches Spiel haben. Obwohl das Zwischenwandelement 15 somit ein zumindest geringes Spiel z.B. in seitlicher Richtung und oder in Längsrichtung hat, ist es an der Schiebernadel 18 in allen Betriebssituationen verliersicher also unverlierbar gehalten. Ein Zwischenelement 15 gemäß Figur 5 wird in dem Nadelkörper 2 positioniert, in dem es vom Nadelrücken 18 aus in die Öffnung 19 eingeführt wird.The intermediate wall element 15 is positively positioned by the foot extension 26 and the bottom 17 cross-engaging portions 27, 28 and centrally. However, the intermediate wall element 15 can, as in particular FIG. 5 implies to have some longitudinal play. Besides, it can have some lateral play. Although the intermediate wall element 15 thus has an at least slight play, for example, in the lateral direction and or in the longitudinal direction, it is held captive on the slide needle 18 in all operating situations so that it is captive. An intermediate element 15 according to FIG. 5 is positioned in the needle body 2 by being inserted into the opening 19 from the needle back 18.

Eine weitere Möglichkeit zur Befestigung des Zwischenwandelements 15 an der Schiebernadel 1 geht aus Figur 6 in Verbindung mit Figur 7 hervor. Die vorstehende Beschreibung gilt für diese Ausführungsform mit Ausnahme der nachfolgend erläuternden Unterschiede unter Zugrundelegung der bereits eingeführten Bezugszeichen entsprechend.Another way to attach the intermediate wall element 15 to the needle 1 is made FIG. 6 combined with FIG. 7 out. The above description applies to this embodiment, with the exception of the differences explained below, based on the already introduced reference numerals.

Die Vertiefung 24 ist hier gemäß Figur 7 und Figur 6 als Schlitz ausgebildet, der sich nicht über die gesamte Breite des Nadelkörpers 2 erstreckt. Jedoch ist die Vertiefung 24 an dem Nadelrücken 18 in Nadellängsrichtung gemessen länger als an dem Boden 17. Der Fußfortsatz 26 weist zwei Abschnitte 29, 30 auf, die den Boden 17 in Schlitzlängsrichtung untergreifen. Die Abschnitte 29, 30 sind beispielsweise durch geeignete Schnitte aus dem Fußfortsatz 26 freigestellt. Sie bilden Federfinger mit Rastflächen 31, 32. Diese Rastflächen 31, 32 greifen unter Vorsprünge 33, 34, die an den stirnseitigen Enden der schlitzartigen Öffnung 19 hinter die Rastflächen 31, 32 ragen. An den von dem Federteil 25 weg weisenden Seiten sind die federnden Abschnitte 29, 30 mit Einführschrägen 35, 36 versehen. Bei dieser Ausführungsform kann das Zwischenwandelement 15 von der Nadeloberseite her in die schlitzartige Öffnung 19 hinein gedrückt werden, worauf es einschnappt und an dem Nadelkörper 2 rastend gehalten bleibt.The recess 24 is here according to FIG. 7 and FIG. 6 formed as a slot which does not extend over the entire width of the needle body 2. However, the depression 24 on the needle back 18 is longer measured in the needle longitudinal direction than on the bottom 17. The foot extension 26 has two sections 29, 30, which engage under the bottom 17 in the slot longitudinal direction. The sections 29, 30 are freed, for example, by suitable cuts from the foot extension 26. They form spring fingers with locking surfaces 31, 32. These locking surfaces 31, 32 engage under projections 33, 34 which protrude at the front ends of the slot-like opening 19 behind the locking surfaces 31, 32. At the side facing away from the spring member 25 sides, the resilient portions 29, 30 with insertion bevels 35, 36 are provided. In this embodiment, the intermediate wall element 15 can be pressed from the top of the needle into the slot-like opening 19, whereupon it snaps and remains latching on the needle body 2.

Es sind abgewandelte Rastverbindungen möglich, wie beispielsweise Figur 8 zeigt. Anstelle einer einzigen Öffnung 19 sind hier zwei schlitzartige Öffnungen 19a, 19b vorgesehen, die in entsprechende Vertiefungen 24a, 24b übergehen können. Wiederum können in jeder Öffnung 19a, 19b Fußfortsätze 26a, 26b gehalten sein, welche das Zwischenwandelement 15 in seitlicher Richtung stabilisieren. Die Fußfortsätze 26a, 26b weisen als Rastfinger dienende federnde Abschnitte 29a, 30a, 29b, 30b auf, die hinter den Rand jeder Öffnung 19a, 19b und somit unter den Boden 17 greifen. Ansonsten kann ergänzend die Beschreibung der Figur 7 zum Verständnis der Figur 8 herangezogen werden, um diese Ausführungsform zu verstehen.There are modified locking connections possible, such as FIG. 8 shows. Instead of a single opening 19, two slot-like openings 19a, 19b are provided here, which can pass into corresponding recesses 24a, 24b. Again, in each opening 19a, 19b foot extensions 26a, 26b may be held, which stabilize the intermediate wall element 15 in the lateral direction. The foot extensions 26a, 26b have resilient portions 29a, 30a, 29b, 30b serving as latching fingers, which engage behind the edge of each opening 19a, 19b and thus under the floor 17. Otherwise, the description of the FIG. 7 to understand the FIG. 8 are used to understand this embodiment.

Figur 9 veranschaulicht wiederum eine Ausführungsform der Schiebernadel 1, bei der das Zwischenwandelement 15 durch dauerhafte Verformung am Platz gesichert ist. Zur Sicherung des Zwischenwandelements 15 sind hier zwei Fußfortsätze 26a, 26b vorgesehen (in Figur 9 links und rechts) wobei jedoch auch lediglich eine oder auch drei oder mehrere derartiger Fußfortsätze vorgesehen sein können. Jeder Fußfortsatz 26a, 26b weist jeweils Abschnitte 27a, 28a, 27b, 28b auf. Diese ragen, wie Figur 9 zeigt, durch die jeweilige schlitzartige Öffnung 19a, 19b. Sie sind dort in Nadellängsrichtung nach vorn oder hinten abgebogen, um unter den Boden 17 zu greifen. Die Vertiefung 24a, 24b kann sich dabei über die gesamte Nadelbreite erstrecken oder auch lediglich schmaler sein. Beispielsweise ist sie auf die Breite des Schlitzes 19a, 19b beschränkt. FIG. 9 again illustrates an embodiment of the slider needle 1, in which the intermediate wall element 15 is secured by permanent deformation in place. To secure the intermediate wall element 15, two foot extensions 26a, 26b are provided here (in FIG FIG. 9 left and right) but only one or even three or more such foot extensions can be provided. Each foot extension 26a, 26b has sections 27a, 28a, 27b, 28b, respectively. These stick out, like FIG. 9 shows, through the respective slot-like opening 19a, 19b. You are there in the needle longitudinal direction bent forwards or backwards to under the Bottom 17 to grab. The recess 24a, 24b may extend over the entire needle width or be only narrower. For example, it is limited to the width of the slot 19a, 19b.

Das Zwischenwandelement 15 gemäß Figur 7, 8 und 9 wird in dem Nadelgrundkörper 2 positioniert, in dem der Fußfortsatz 26 von der Oberseite der Nadel in die Öffnung 19 eingeführt und verrastet wird. Zwischenwandelement 15 kann wiederum mit etwas Spiel gehalten sein, das in Längsrichtung und/oder Querrichtung gegeben sein kann.The intermediate wall element 15 according to FIG. 7 . 8 and 9 is positioned in the needle body 2, in which the foot extension 26 is inserted from the top of the needle in the opening 19 and locked. The intermediate wall element 15 can in turn be held with some play, which can be given in the longitudinal direction and / or transverse direction.

Eine weitere Ausführungsmöglichkeit veranschaulicht Figur 10. Dort ist das Zwischenwandelement 15 von der Nadelrückseite her in dem Nadelkörper 2 eingesetzt. Der Fußfortsatz 26 ist hier in Nadellängsrichtung länger als der Federteil 25. An dem Federteil 25 können durch Anbringen einer geeigneten Ausnehmung 43, 44 federnde Finger 37, 38 freigestellt sein, deren Stirnseiten 39, 40 sich als Rastflächen auf dem Boden 17 abstützen. Die sich in Längsrichtung erstreckende den jeweiligen Stirnseiten 39, 40 gegenüber liegende Nasen 41, 42 des Fußfortsatzes 26 greifen dabei unter den Boden 17.Another embodiment illustrated FIG. 10 , There, the intermediate wall element 15 is inserted from the needle back side in the needle body 2. The foot extension 26 is here longer in the needle longitudinal direction than the spring member 25. On the spring member 25 by attaching a suitable recess 43, 44 resilient fingers 37, 38 are released, whose end faces 39, 40 are supported as latching surfaces on the bottom 17. The lugs 41, 42 of the foot extension 26, which extend in the longitudinal direction and which face the respective end faces 39, 40, engage under the floor 17.

Eine weitere Möglichkeit zur Befestigung des Zwischenwandelements 15 an der Schiebernadel 1 geht aus Figur 11 hervor. Die vorstehende Beschreibung gilt für diese Ausführungsform mit Ausnahme der nachfolgend erläuternden Unterschiede unter Zugrundelegung der bereits eingeführten Bezugszeichen entsprechend. Zusätzlich zu den seitlich weggebogenen Abschnitten 27, 28 ähnlich wie bei einem Zwischenwandelement 15 gemäß Figur 5 kann ein Zwischenwandelement 15 gemäß Figur 11 wenigstens ein Clip in Form eines federnd gehaltenen Teils 29 aufweisen. Dieses federnd gelagerte Teil 29 weist eine Stirnseite 40 auf die im eingebauten Zustand mit dem Boden 17 des Schieberkanals zusammenwirkt. Ein Zwischenwandelement 15 gemäß Figur 11 wird in dem Nadelgrundkörper 2 positioniert, in dem es vom Nadelrücken 18 aus mit einer Drehbewegung in die Öffnung 19 eingeführt wird. Zunächst wird das dem Clip 29 gegenüberliegende Ende des Zwischenwandelements 15 in die Öffnung 19 eingeführt und dann mittels einer Schwenkbewegung arretiert. Dabei wird die Stirnseite 40 des Clips 29 oberhalb des Bodens 17 positioniert. Das Zwischenwandelement 15 kann so in den Nadelgrundkörper 2 eingeclipst werden.Another way to attach the intermediate wall element 15 to the needle 1 is made FIG. 11 out. The above description applies to this embodiment, with the exception of the differences explained below, based on the already introduced reference numerals. In addition to the laterally bent portions 27, 28 similar to an intermediate wall element 15 according to FIG FIG. 5 can an intermediate wall element 15 according to FIG. 11 have at least one clip in the form of a resiliently held part 29. This spring-mounted part 29 has an end face 40 in the installed state cooperates with the bottom 17 of the slide channel. An intermediate wall element 15 according to FIG. 11 is positioned in the needle body 2 by being inserted from the needle back 18 into the opening 19 with a rotational movement. First, the clip 29 opposite end of the intermediate wall element 15 is inserted into the opening 19 and then locked by means of a pivoting movement. In this case, the end face 40 of the clip 29 is positioned above the bottom 17. The intermediate wall element 15 can thus be clipped into the needle base body 2.

Erfindungsgemäß weist die Schiebernadel 1 ein Zwischenwandelement 15 auf, das durch einen Öffnung 19 im Nadelgrundkörper 2, zum Beispiel von unten her eingeclipst ist. Das Zwischenwandelement 15 ist so ausgeformt, dass es zwar leicht eingesetzt werden kann, trotzdem aber durch Formschluss sicher, gegebenenfalls aber mit etwas Spiel im Nadelgrundkörper 2 gehalten ist. Es weist einen Federteil 25 und einen Fußfortsatz 26 auf, der mit dem Boden 17 des Schieberschlitzes zusammenwirkt. Der Fußfortsatz 26 weist vorzugsweise zwei gegensinnig umgebogene Abschnitte 27, 28 27a, 28a auf. Diese können in Querrichtung oder in Längsrichtung des ansonsten flachen Zwischenwandelements 15 gebogen sein. Der Rücken 18 des Nadelgrundkörpers 2 weist im Bereich der Öffnung 19, die in Form eines des Einführschlitzes ausgebildet sein kann eine Vertiefung 24 auf, so dass der umgebogene Abschnitt 27, 28, 27a, 28a nicht über den Nadelrücken 18 hinausragen kann. Der Federteil 25 ist vorzugsweise einstückiger Bestandteil des Zwischenwandelements 15. Dadurch wird der Verlust des Federteils 15 ausgeschlossen. Eine kostengünstige Herstellung wird ermöglicht.According to the invention, the slider needle 1 has an intermediate wall element 15 which is clipped in through an opening 19 in the needle base body 2, for example from below. The intermediate wall element 15 is formed so that, although it can be easily used, but still safe by positive engagement, but possibly held with some play in the needle body 2. It has a spring part 25 and a foot extension 26 which cooperates with the bottom 17 of the slide slot. The foot extension 26 preferably has two oppositely bent portions 27, 28 27a, 28a. These can be bent in the transverse direction or in the longitudinal direction of the otherwise flat intermediate wall element 15. The back 18 of the needle body 2 has, in the region of the opening 19, which may be in the form of one of the insertion slot, a recess 24, so that the bent portion 27, 28, 27 a, 28 a can not protrude beyond the needle back 18. The spring member 25 is preferably an integral part of the intermediate wall element 15. This eliminates the loss of the spring member 15. An inexpensive production is possible.
