Definitions
- the invention relates to a knitting needle according to the preamble of claim 1.
- the needle hook In order for the thread to be inserted into the needle hook to be securely grasped by the needle hook, the needle hook should be relatively large on the one hand. On the other hand, in order to enable a slight knocking off of the loop formed when the needle hook is closed, it should on the other hand be relatively small, since here a large needle hook would lead to a strong widening of the stitch.
- the knitting needles according to the prior art represent a compromise with respect to these two requirements, which is optimal neither for the thread insert nor for the knocking off of the stitches.
- tongue needles are known from the prior art, in which a relatively shallow rise on the closed needle hook is achieved in that a relatively long tongue is used.
- this design has the serious disadvantage that the Nadelaustriebsweg, which is necessary in order to allow the stitching stitch to slide behind the open tongue, extended and thus a wider needle lock is required to control the needle movement.
- Another disadvantage is that the overall diameter of the needles in the region of the hook can not be reduced by this measure.
- Needles for knitting machines are known with a needle hook, which has particularly long legs. However, the distance between the legs is the same when the tongue is closed and open.
- the US 1,097,732 describes a knitting needle with a resilient free leg of the needle hook.
- the closure of the free leg is made by closing the needle tongue, but the movement of the free leg is not defined.
- the free leg bends depending on the force of the tongue at different locations and can still move resiliently with the tongue closed.
- the present invention has for its object to provide a knitting needle for knitting machines, with both a secure thread insert as well as a gentle knocking off of stitches can be ensured.
- the knitting needle according to the invention is thus characterized by the fact that the opening width of the hook is adjustable. It is advantageous if the free end portion of the needle hook with the tongue open or slider open the largest distance to the opposite end and with closed tongue or closed slide has the smallest distance to the opposite end. If the slider or the tongue are open, the knitting needle is ready for thread insertion. For a good and safe thread insert a large opening width of the needle hook is desired. When the slide is closed or the tongue is closed, the needle serves to knock off a stitch. For this purpose, the smallest possible diameter of the needle hook is advantageous, which can be achieved by reducing the opening width.
- the distance between the two end regions can be automatically reduced so that no further control elements acting on the free end region of the needle hook need to be provided.
- the mesh already causes the closing of the tongue and is now also used to Opening the hook to reduce and thereby facilitate their own knocking.
- a control can be used, which acts on the tongue.
- the free end region may be formed elastically resilient. In the relaxed state, it has the greatest distance to the opposite end region. By closing the tongue or the slider, however, it can be moved towards the end region adjoining the needle shank, whereby the opening width of the hook and thus also the diameter of the needle in the region of the needle hook are reduced.
- a cross-sectional reduction is provided between the free end region of the needle hook and the hook head. This allows a kinking of the free end region relative to the hook head and thus a change in the distance of the free end region for integrally formed on the needle shank end region.
- the cross-sectional reduction can be formed for example by a recess or groove on the hook inside. However, it is also possible to form the cross-sectional reduction by a circumferential groove on the needle hook.
- the boundary is formed by abutment surfaces at the location of the necking between the free end portion and the needle head.
- the limitation of the movement of the free end portion of the needle hook can also be done by limiting the closing movement of the tongue or the slider. This is particularly useful when the movement of the free end portion of the needle hook is done solely by the tongue or the slider or the mesh located on this.
- a stop surface or a stop pin for the tongue in its closed position in the region of the reed in the needle shaft can be arranged.
- the tongue can also have a cross-sectional widening, which prevents further immersion of the tongue in the receiving slot of the needle shaft for the tongue in the closed state of the tongue.
- the tongue spoon may have a stop surface for the free end of the needle hook.
- the tongue and the free end of the needle hook stiffen against each other and thus prevent both further movement of the tongue and the free end of the needle hook.
- the slider can at least partially perform a pivoting movement during closing, as a result of which the free end region of the needle hook is moved closer to the end region adjoining the needle shank.
- the clamping force of the stitch to be rejected can also be used here.
- Fig. 1 is a first latch needle 1 with a needle hook 2, which includes a hook space 20 shown.
- the needle hook 2 has a free end region 22 and an end region 3 formed on a needle shaft 6 via a needle breast 4.
- the hook head 21 is located between the two end regions 22, 3.
- the tongue shaft 6 also has a tongue 5 pivotally mounted on a rotary bearing 50, wherein the tongue 5 is arranged in the needle shaft 6 in a tongue slot (not shown).
- the tongue 5 can by a mesh 100 from the in Fig. 1a shown opened position in the in the Fig. 1c, 1d shown closed position to be pivoted. If, in addition, a tongue spring, not shown here, is provided, the tongue 5 can also assume intermediate positions, for example a half-opened position or a half-closed position.
- the free end portion 22 of the needle hook 2 is elastically resilient, while the opposite end portion 3 is rigid.
- the illustrated embodiment of the needle 1 is not covered by the invention without a cross-sectional reduction between the end portion 22 and the hook head 21.
- the distance H of the free end region 22 to the end region 3 can be changed by the elastically resilient properties of the end region 22. In the in Fig. 1a shown opened position of the tongue 5, the distance has its greatest value H, ie the hook space 20 is here largest. A thread insert in the hook space 20 is easily possible even with thick threads or multiple threads.
- the spoon 53 of the tongue 5 now abuts against the tip 23 of the free end portion 22 of the needle hook 2.
- the distance H of the free end region 22 to the end region 3 initially remains unchanged.
- the loop 100 slides onto the tongue 5. Due to the elasticity of the mesh 100 and the elastic properties of the end region 22, it is pressed against the opposite end region 3 of the hook 2, whereby the distance H 'between the free end region 22 and the end region 3 is established. Since the distance H 'is smaller than the distance H undergoes the mesh 100 upon further sliding towards the tip of the tongue from in Fig. 1c shown position in the Fig. 1d shown position only a small expansion, so that the knocking of the mesh 100 can be done safely and yarn gently.
- the resilient properties of the free end portion 22 are achieved by a cross-sectional reduction. However, these properties could also be achieved by the choice of a corresponding material with bending spring properties (not covered by the invention).
- the areas 21 and 3 of the needle hook 2, however, must have a high strength and rigidity.
- Fig. 2 now shows a further embodiment of the needle 1 Fig. 1 , the only difference to the needle Fig. 1 It is that at the top of the free end portion 22 of the needle hook 2, a cross-sectional enlargement 220 is arranged, which provides a larger contact surface for the tongue spoon 53 with the tongue 5 closed. Also the needle 1 off Fig. 2 is not included in the invention without a cross-sectional reduction between the end portion 22 and the needle head 21.
- needle 1 has a stiffened free end portion 22 of the needle hook 2.
- the mobility of the end portion 22 is achieved here by a cross-sectional reduction in the form of a groove 230 in the transition region between the free end portion 22 and the hook head 21.
- the cross-sectional reduction achieved by the groove 230 also leads to a resilient mobility of the free end portion 22 as in the case of the needle 1 Fig. 1 ,
- Fig. 4 now shows a needle, in as well as in Fig. 3 a cross-sectional reduction between the free end portion 22 and the hook head 21 is provided, but here is designed as a narrow recess 240.
- the free end portion 22 has as well as the needle Fig. 3 a cross section equal to that of a needle of corresponding fineness without a movable end portion.
- FIG. 5 shows a needle with a cross-sectional reduction between the hook head 21 and the free end portion 22, which is achieved here by a circumferential groove 250.
- FIG. 6 Another possibility, not included in the invention, of obtaining a movable free end region 22 'on a knitting needle 1 is shown Fig. 6 , Here is a hinge 24 between the hook head 21 and the free end portion 22 'of the hook 2 is arranged.
- a hinge 24 between the hook head 21 and the free end portion 22 'of the hook 2 is arranged.
- the free end 22 ' is held in the position shown when no stitch is cut off over the tongue 5.
- the free end portion 22 'of the hook 2 is pivoted against the force of this spring.
- the Fig. 7 - 11 show different ways of moving the free end 22 of the in Fig. 1 shown needle 1 in the direction of the opposite end portion 3 to limit.
- Fig. 7 the closing movement of the tongue 5 is mechanically limited, so that the distance of the free end portion 22 to the opposite end region does not fall below the value H 'when the stitch located on the closed needle tongue 5 pushes the tongue spoon 53 against the end portion 22 of the hook 2.
- the position of the closed tongue 5 and the end portion 22 of the hook 2 is shown in the unloaded state with solid lines and in the loaded state with dash-dotted lines.
- the limitation of the closing movement of the tongue 5 is realized by a bevel 60 in the tongue slot 61, on which the tongue 5 rests with a region of its underside 51.
- the limitation of the closing movement of the tongue 5 is achieved by a bolt 7, which is mounted transversely to the longitudinal direction of the tongue slot 61 in the needle shaft 6 and on which the tongue 5 rests in the closed state with a portion of its bottom 51.
- the tongue 5 has a lying behind the pivot bearing 50 extension 54, which comes with a closed tongue 5 against a pin 8 to the plant.
- the bolt 8 also extends again across the tongue slot 61 and is mounted in the needle shaft 6.
- the tongue 5 has a cross-sectional widening 55 which is arranged on one or both sides of the tongue 5 at a distance from its rotary bearing 50.
- this cross-sectional spread rests on the cheeks 65 of the tongue slot 61 and thus prevents further insertion of the tongue 5 into the tongue slot 61.
- the limitation of the movement of the tongue 5 is achieved in that the free end portion 22 of the hook 2 at its tip has a surface 26 which comes into contact with a surface 56 of a cavity 57 on the underside of the tongue 53, when the on the tongue 5 located mesh has brought the end portion 22 of the needle hook 2 and the tongue 5 in its full closed position.
- a barrier which also limits the pivoting of the free end portion 22.
- FIGS. 12 and 13 show two not included in the invention slide needles 1 '.
- a slider 9 To close the hook 2 of these needles and to move the free end portion 22 of the hook 2 on the opposite end portion 3 to a slider 9 is used.
- the hook 2 with its sections 21, 22 and 3 corresponds to the hook of the needle 1 Fig. 1 .
- the slider 9 is moved by means not shown here lock parts in the directions V and R of the double arrow P.
- the position of the closed slide 9 and the free end portion 22 of the hook 2 is shown in the unloaded state with solid lines and in the loaded state with dash-dotted lines.
- the slider 9 is guided in a guide groove 62.
- the slider 9 In the unloaded state, the slider 9 is located with its upper side 92 on the upper side 64 of the guide groove 62.
- the loaded state of the slider 9 In the loaded state of the slider 9 is located with its bottom 91 on the bottom 63 of the guide groove 62 at. Due to the resilience of the stitching stitch, which is located on the slider, the slider 9 is pressed against the free end portion 22 of the hook 2 and thus reduces its distance from the value H to the value H '.
- the pressure of the slider 9 against the free end portion 22 of the hook 2 can also be done by a control, not shown, which acts on the slide 9.
- the slider 9 of the needle 1 'off Fig. 12 is mounted pivotally as a whole
- the slider 9 of the needle 1 'from Fig. 13 a tip 94 which is pivotable.
- the groove 62, in which the slider 9 is guided, has approximately the same height as the slider 9.
- the mobility of the tip 94 of the slider 9 is achieved by a recess 93. In the region of the recess 93, the tip 94 can bend relative to the remaining portion of the slider 9 and occupy the dot-dash line position. This movement can go through again the clamping force of the stitching stitch, which is located on the slider 9, are triggered.
- the distance of the free end portion 22 of the hook from the value H decreases to the value H '. Also in this design of the slider 9, the movement of the tip 94 can be triggered by a control and / or supported.

Description
Die Erfindung betrifft eine Stricknadel nach dem Oberbegriff des Anspruchs 1.The invention relates to a knitting needle according to the preamble of
Bei Stricknadeln für Strickmaschinen sind zwei entgegengesetzte Anforderungen an die Größe des Nadelhakens möglichst gut zu erfüllen: Damit der in den Nadelhaken einzulegende Faden sicher vom Nadelhaken erfasst werden kann, sollte der Nadelhaken einerseits relativ groß sein. Um bei geschlossenem Nadelhaken ein leichtes Abschlagen der gebildeten Masche zu ermögliche, solle er aber andererseits relativ klein sein, da hier ein großer Nadelhaken zu einem starken Aufweiten der Masche führen würde.With knitting needles for knitting machines, two opposite requirements for the size of the needle hook are to be fulfilled as well as possible: In order for the thread to be inserted into the needle hook to be securely grasped by the needle hook, the needle hook should be relatively large on the one hand. On the other hand, in order to enable a slight knocking off of the loop formed when the needle hook is closed, it should on the other hand be relatively small, since here a large needle hook would lead to a strong widening of the stitch.
Die Stricknadeln nach dem Stand der Technik stellen bezüglich dieser beiden Anforderungen einen Kompromiss dar, der weder für die Fadeneinlage noch für das Abschlagen der Maschen optimal ist.The knitting needles according to the prior art represent a compromise with respect to these two requirements, which is optimal neither for the thread insert nor for the knocking off of the stitches.
So zeigt beispielsweise die
Aus dem Stand der Technik sind außerdem Zungennadeln bekannt, bei denen ein relativ flacher Anstieg auf den geschlossenen Nadelhaken dadurch erreicht wird, dass eine relativ lange Zunge verwendet wird. Diese Ausgestaltung hat jedoch den gravierenden Nachteil, dass sich der Nadelaustriebsweg, der notwendig ist, um die abzuschlagende Masche hinter die geöffnete Zunge gleiten zu lassen, verlängert und somit zur Steuerung der Nadelbewegung ein breiteres Nadelschloss benötigt wird.In addition, tongue needles are known from the prior art, in which a relatively shallow rise on the closed needle hook is achieved in that a relatively long tongue is used. However, this design has the serious disadvantage that the Nadelaustriebsweg, which is necessary in order to allow the stitching stitch to slide behind the open tongue, extended and thus a wider needle lock is required to control the needle movement.
Ein weiterer Nachteil besteht darin, dass sich der Gesamtdurchmesser der Nadeln im Bereich des Hakens durch diese Maßnahme nicht verringern lässt.Another disadvantage is that the overall diameter of the needles in the region of the hook can not be reduced by this measure.
Aus der
Die
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Stricknadel für Strickmaschinen zu schaffen, mit der sowohl eine sichere Fadeneinlage als auch ein schonendes Abschlagen von Maschen gewährleistet werden kann.The present invention has for its object to provide a knitting needle for knitting machines, with both a secure thread insert as well as a gentle knocking off of stitches can be ensured.
Die Aufgabe wird mit einer Stricknadel mit den Merkmalen des Anspruchs 1 gelöst.The object is achieved with a knitting needle with the features of
Die erfindungsgemäße Stricknadel zeichnet sich also dadurch aus, dass die Öffnungsweite des Hakens verstellbar ist. Dabei ist es von Vorteil, wenn der freie Endbereich des Nadelhakens bei geöffneter Zunge oder geöffnetem Schieber den größten Abstand zum gegenüberliegenden Endbereich und bei geschlossener Zunge oder geschlossenem Schieber den kleinsten Abstand zum gegenüberliegenden Endbereich aufweist. Sind der Schieber oder die Zunge geöffnet, so ist die Stricknadel zur Fadeneinlage bereit. Für eine gute und sichere Fadeneinlage ist eine große Öffnungsweite des Nadelhakens erwünscht. Bei geschlossenem Schieber oder geschlossener Zunge dient die Nadel dem Abschlagen einer Masche. Hierfür ist ein möglichst geringer Durchmesser des Nadelhakens von Vorteil, was durch eine Verringerung der Öffnungsweite erreicht werden kann.The knitting needle according to the invention is thus characterized by the fact that the opening width of the hook is adjustable. It is advantageous if the free end portion of the needle hook with the tongue open or slider open the largest distance to the opposite end and with closed tongue or closed slide has the smallest distance to the opposite end. If the slider or the tongue are open, the knitting needle is ready for thread insertion. For a good and safe thread insert a large opening width of the needle hook is desired. When the slide is closed or the tongue is closed, the needle serves to knock off a stitch. For this purpose, the smallest possible diameter of the needle hook is advantageous, which can be achieved by reducing the opening width.
Bevorzugt kann durch Schließen der Zunge oder des Schiebers der Abstand der beiden Endbereiche automatisch verringerbar sein, sodass keine weiteren, auf den freien Endbereich des Nadelhakens einwirkenden Steuerelemente vorgesehen werden müssen. Dabei kann nach Schließen der Zunge oder des Schiebers der freie Endbereich des Nadelhakens mittels der Spannkraft der auf der Zunge oder dem Schieber befindlichen, abzuschlagenden Masche gegen den an den Nadelschaft angrenzenden Endbereich bewegbar sein. Bei einer Zungennadel bewirkt die Masche schon das Schließen der Zunge und wird nun auch dazu genutzt, die Öffnungsweite des Hakens zu vermindern und dadurch ihr eigenes Abschlagen zu erleichtern.Preferably, by closing the tongue or the slider, the distance between the two end regions can be automatically reduced so that no further control elements acting on the free end region of the needle hook need to be provided. In this case, after closing the tongue or the slider of the free end portion of the needle hook by means of the clamping force of the located on the tongue or the slide, be beaten stitch against the adjoining the needle shank end portion. In a latch needle, the mesh already causes the closing of the tongue and is now also used to Opening the hook to reduce and thereby facilitate their own knocking.
Zur Verminderung der Öffnungsweite des Hakens kann jedoch auch ein Steuerelement eingesetzt werden, das die Zunge beaufschlagt.To reduce the opening width of the hook, however, a control can be used, which acts on the tongue.
Für die konkrete Ausgestaltung einer erfindungsgemäßen Stricknadel mit einem änderbaren Abstand zwischen dem freien und dem an den Nadelschaft angeformten Endbereich des Nadelhakens gibt es unterschiedliche Möglichkeiten.For the specific embodiment of a knitting needle according to the invention with a changeable distance between the free end portion and the end portion of the needle hook formed on the needle shank, there are different possibilities.
Bei einer ersten Ausgestaltung kann der freie Endbereich elastisch federnd ausgebildet sein. Im entspannten Zustand weist er den größten Abstand zum gegenüberliegenden Endbereich auf. Durch Schließen der Zunge oder des Schiebers kann er dagegen auf den an den Nadelschaft angrenzenden Endbereich zubewegt werden, wodurch sich die Öffnungsweite des Hakens und damit auch der Durchmesser der Nadel im Bereich des Nadelhakens verringert.In a first embodiment, the free end region may be formed elastically resilient. In the relaxed state, it has the greatest distance to the opposite end region. By closing the tongue or the slider, however, it can be moved towards the end region adjoining the needle shank, whereby the opening width of the hook and thus also the diameter of the needle in the region of the needle hook are reduced.
Um den freien Endbereich des Nadelhakens beweglich auszugestalten, ist zwischen dem freien Endbereich des Nadelhakens und dem Hakenkopf eine Querschnittsverminderung vorgesehen. Diese ermöglicht ein Abknicken des freien Endbereichs gegenüber dem Hakenkopf und damit eine Veränderung des Abstands des freien Endbereichs zum an den Nadelschaft angeformten Endbereich. Die Querschnittsverminderung kann beispielsweise durch eine Ausnehmung oder Auskehlung an der Hakeninnenseite gebildet sein. Es ist jedoch auch möglich, die Querschnittsverminderung durch einen umlaufenden Einstich am Nadelhaken zu bilden.In order to make the free end region of the needle hook movable, a cross-sectional reduction is provided between the free end region of the needle hook and the hook head. This allows a kinking of the free end region relative to the hook head and thus a change in the distance of the free end region for integrally formed on the needle shank end region. The cross-sectional reduction can be formed for example by a recess or groove on the hook inside. However, it is also possible to form the cross-sectional reduction by a circumferential groove on the needle hook.
Weitere Vorteile ergeben sich, wenn eine Begrenzung für die Bewegung des freien Endbereichs des Nadelhakens vorgesehen ist. Diese begrenzt die Bewegung des freien Endbereichs des Nadelhakens in Richtung auf den an den Nadelschaft angrenzenden Endbereich.Further advantages arise when a limit is provided for the movement of the free end portion of the needle hook. This limits the movement of the free end portion of the needle hook towards the end portion adjacent to the needle shank.
Diese Begrenzung der Bewegung des freien Endbereichs kann auf unterschiedliche Weise erfolgen. Bei einer ersten bevorzugten Ausgestaltung wird die Begrenzung durch Anschlagflächen an der Stelle der Querschnittsverminderung zwischen dem freien Endbereich und dem Nadelkopf gebildet.This limitation of the movement of the free end region can be done in different ways. In a first preferred embodiment, the boundary is formed by abutment surfaces at the location of the necking between the free end portion and the needle head.
Die Begrenzung der Bewegung des freien Endbereichs des Nadelhakens kann jedoch auch durch eine Begrenzung der Schließbewegung der Zunge oder des Schiebers erfolgen. Dies ist vor allem dann zweckmäßig, wenn die Bewegung des freien Endbereichs des Nadelhakens allein durch die Zunge oder den Schieber bzw. der auf diesem befindlichen Masche erfolgt.However, the limitation of the movement of the free end portion of the needle hook can also be done by limiting the closing movement of the tongue or the slider. This is particularly useful when the movement of the free end portion of the needle hook is done solely by the tongue or the slider or the mesh located on this.
Dazu kann beispielsweise bei Ausgestaltung der Stricknadel als Zungennadel eine Anschlagfläche oder ein Anschlagbolzen für die Zunge in ihrer Schließposition im Bereich des Zungenlagers im Nadelschaft angeordnet sein.For this purpose, for example, in the configuration of the knitting needle as a latch needle a stop surface or a stop pin for the tongue in its closed position in the region of the reed in the needle shaft can be arranged.
Die Zunge kann jedoch auch eine Querschnittsverbreiterung aufweisen, die im geschlossenen Zustand der Zunge ein weiteres Eintauchen der Zunge in den Aufnahmeschlitz des Nadelschafts für die Zunge verhindert.However, the tongue can also have a cross-sectional widening, which prevents further immersion of the tongue in the receiving slot of the needle shaft for the tongue in the closed state of the tongue.
Bei einer weiteren Ausgestaltung kann der Zungenlöffel eine Anschlagfläche für das freie Ende des Nadelhakens aufweisen. Hier stemmen sich somit die Zunge und das freie Ende des Nadelhakens gegeneinander und verhindern somit sowohl eine weitere Bewegung der Zunge als auch des freien Endes des Nadelhakens.In a further embodiment, the tongue spoon may have a stop surface for the free end of the needle hook. Here, therefore, the tongue and the free end of the needle hook stiffen against each other and thus prevent both further movement of the tongue and the free end of the needle hook.
Ist die Stricknadel als Schiebernadel ausgebildet, so kann der Schieber zumindest bereichsweise beim Schließen eine Schwenkbewegung ausführen, wodurch der freie Endbereich des Nadelhakens näher an den an den Nadelschaft angrenzenden Endbereich bewegt wird. Für die Schwenkbewegung des Schiebers bzw. des Schieberbereichs kann auch hier die Spannkraft der abzuschlagenden Masche genutzt werden.If the knitting needle is designed as a slider needle, then the slider can at least partially perform a pivoting movement during closing, as a result of which the free end region of the needle hook is moved closer to the end region adjoining the needle shank. For the pivoting movement of the slider or the slider area, the clamping force of the stitch to be rejected can also be used here.
Außerdem ist es auch bei Schiebernadeln aus den gleichen Gründen wie bei Zungennadeln von Vorteil, wenn eine Begrenzung für die Schwenkbewegung des Schiebers oder des Schieberbereichs vorgesehen ist. Diese Begrenzung kann vorteilhafterweise durch eine entsprechende Ausgestaltung der Schiebernut erfolgen.In addition, it is also advantageous in slider needles for the same reasons as with latch needles, if a limitation for the pivotal movement of the slider or the slider area is provided. This limitation can be advantageously carried out by a corresponding configuration of the slide groove.
Nachfolgend werden bevorzugte Ausführungsbeispiele erfindungsgemäßer und nicht erfindungsgemäßer Stricknadeln anhand der Zeichnungen näher beschrieben.Hereinafter, preferred embodiments of inventive and not inventive knitting needles are described in detail with reference to the drawings.

Claims (15)
- Knitting needle with a needle stem (6) and a needle hook (2) formed into the latter and a latch (5) or a slider (9) for the closing of the needle hook (2), wherein the free end region (22) of the needle hook (2) is variable in its distance from the end region (3) of the needle hook (2) adjacent to the needle stem (6), characterised in that a reduction in cross-section is provided between the free end region (22) of the needle hook (2) and the hook head (21).
- Knitting needle according to claim 1, characterised in that, through the closing of the latch (5) or of the slider, the distance (H, H') of the two end regions (22, 3) from one another is reducible.
- Knitting needle according to claim 1 or 2, characterised in that the free end region (22) of the needle hook (2) is displaceable towards the end region (3) adjacent to the needle stem (6) by means of the tension force of the loop (100) to be cast off disposed on the latch (5) or the slider (9).
- Knitting needle according to one of the preceding claims, characterised in that the free end region (22) is constituted in an elastic resilient manner.
- Knitting needle according to one of the preceding claims, characterised in that the reduction in cross-section is formed by a recess (230) or throat (240) in the inside of the hook.
- Knitting needle according to one of claims 1 to 5, characterised in that the reduction in cross-section is formed by a peripheral puncture (250) in the needle hook.
- Knitting needle according to one of the preceding claims, characterised in that a limitation for the movement of the free end region (22) of the needle hook (2) is provided.
- Knitting needle according to claim 7, characterised in that the limitation is formed by the stopping faces at the position of the reduction in cross-section between the free end region (22) and the hook head (21).
- Knitting needle according to claim 7, characterised in that the limitation takes place through a limitation of the closing movement of the latch (5) or of the slider (9).
- Knitting needle according to claim 9, characterised in that a stopping face (60) or stopping pin (7, 8) for the latch (5) is arranged in the region of the latch mounting (50) in the needle stem (6).
- Knitting needle according to claim 9, characterised in that the latch (5) comprises a widening in cross-section (55), which, in the closed condition of the latch (5), prevents a further penetration of the latch (5) into the receiving slot (61) of the needle stem (6) for the latch (5).
- Knitting needle according to claim 9, characterised in that the latch spoon (53) comprises a stopping face (56) for the free end (22) of the needle hook (2).
- Knitting needle according to one of claims 1 to 9, characterised in that the needle (1') is a slider needle and the slider (9) performs a pivoting movement at least in regions during closing, thereby displacing the free end region (22') of the needle hook (2) nearer to the end region (3) adjacent to the needle stem (6).
- Knitting needle according to claim 13, characterised in that a limitation is provided for the pivoting movement of the slider (9) or of the slider region.
- Knitting needle according to one of the preceding claims, characterised in that, with closed latch (5) or closed slider (9), the mutual distance of the two end regions (22, 22', 3) is reducible through application of pressure of the latch (5) or of the slider (9) by means of a control element.
