EP2202339B1 - Sock liner made of knitted fabric and method for its manufacture - Google Patents

Description

The invention relates to a footlet of knitwear, comprising a pocket or bag-like toe piece, a bag-like heel portion and a mid-section between the toes and the heel portion containing the sole, together defining an edge entry slot for a wearer's foot , In addition, the invention relates to a method for producing such a footlet.

Fashionable booties or short socks require that they cover and encase the foot of the wearer or wearer in the toe and heel area as well as along the sole, but that they are not visible from the outside as far as possible when the footwear is low-cut. In addition, a firm grip of the footlet or sock must be ensured on the foot, in particular to prevent the footlet or the sock from being accidentally stripped over the heel when worn.

Simple booties, which consist only of a round-knit hose, which is closed at one end by a seam, do not meet these requirements in the rule. The FR-1 079 155 A1 discloses an improved embodiment of such a bootlet in such a way that the bootlet knitted as a simple tube and closed at its end by means of a seam approximately at half the height of the foot Hose is provided with a knitted bag, which is made by reducing and increasing mesh in the pendulum course of the circular knitting machine and which serves as a toe part in use for receiving the toes of the wearer. For better adaptation to the anatomical shape of the foot, the fabric can be cut in the area of the seam closing the hose before it is attached. Nevertheless, the fit of the footlet to be achieved in this way is not sufficient for many requirements. This also applies to another from the DE 931 00 A1 known Füßling, which consists of a relatively long trained tip portion and a relatively short trained heel part between which an intermediate piece of constant width extends. The end of the tip part and the heel part are bound off after the production of the blank, wherein the edge of the opening is provided with "thread rubber". With this type of booties, the long lace part is often undesirable. Also, in the entire edge of the manhole round incorporated rubber thread, as he is required to achieve a good grip on the foot is felt when wearing as disadvantageous. A basically similar footlet is finally from the EP 0 632 972 B1 known, having two oppositely arranged, each worked in the manner of a heel bag parts which are interconnected by a sole containing middle part in such a way that the connection between the individual parts is seamless and continuous, so that the whole footlet including its edge surrounding the manhole is completely seamless.

Based on this prior art, the present invention seeks to provide a knitted bootlet, even with a very large neckline, especially in the toe area, by a reliable hold distinguished at the foot of the wearer and the wearer and has a perfect fit.

To solve this problem, the invention Füßling on the features of claim 1.

The footlet according to the invention, which is knitted seamlessly with a pocket-like toe part, a bag-like heel part and a middle part extending between the toe and heel parts, has a heel part knitted on the middle part, which worked in the manner of a bag open on one side and is closed by a seam which is arranged running transversely to the sole. This seam may be a warp seam, a Rosso seam or another suitable seam, and in a preferred embodiment is located in the region of the sole. In certain embodiments, however, it may also be appropriate to arrange the transverse seam in the upper heel region near the edge.

The access opening of the footlet is advantageously limited by an elastic edge knitted onto the toe part and / or the heel part, while in the middle part at least a region of the edge bounding the entry opening is knitted with a substantially inelastic thread.

The new footlet can be formed with an extremely large neckline in the toe area of the wearer without degrading the fit. It was recognized that it is important to make the tip of the foot very elastic and the heel as inelastic as possible. This is achieved by the seam running transversely to the sole. In addition, the upper edge of the footlet usually allowed do not reach so high that it is visible from the outside with low-cut footwear. To achieve this, the transverse seam is laid down, ie in the area of the sole.

The bag-like heel part may be knitted in the manner of a known wedge heel by corresponding reduction and increase of stitches. In this embodiment of the heel bag results approximately in the middle of the heel bag on both sides of the foot in each case an outwardly extending reduction edge. Since the knits of the fabric are tightened at the ends of the reduction edge, beads arise at these points, which are occasionally undesirable. Also occur at the inner end of the abatement edge spikes in the stitch-forming yarns, which involve the risk of the formation of holes at these points in sensitive yarns. A remedy and a substantial improvement of the fit of the footlet can be achieved by the heel part is working with a novel "inverted" reduction and increase, wherein the bag forming the heel part has two mitigation edges emanating from the areas of the edge of the manhole extend the sole to the ends of the transverse seam and on each side at an angle, for example, of 90 °, with each other. Unwanted accumulations of material in the heel area, which is usually exposed to particularly heavy abrasion, are thus avoided.

Inventive methods for producing a footlet of the type described above are the subject matter of patent claims 11, 12 and 17.

• Zuerst wird mit einer ersten Nadelgruppe im Pendelgang ein elastischer Rand für das Fußspitzenteil des Füßlings gestrickt. Dieser Rand besteht aus einigen im Pendelgang gestrickten Teilmaschenreihen, in denen ein zweckentsprechender elastischer Faden verarbeitet ist.

In such a procedure, which is based on a and increasing device equipped knitting machine, in particular circular knitting machine, is executed with two separately controllable groups of needles, the footlet is knitted beginning with the toe in the following sequence:

• First, an elastic edge for the toe part of the footlet is knitted with a first needle group in the pendulum run. This edge consists of some knitted in the pendulum course sub-mesh rows in which a suitable elastic thread is processed.

Subsequently, seamlessly with the needles of the first group of needles, a pocket or bag-like toe piece is knitted by reducing and then increasing stitches in the pendulum run. Next, likewise with the needles of the first group of needles, a middle part seamlessly connected to the toe piece, the sole of the footlet is knitted, to which a margin bordering the access opening for the wearer of the footlet is replaced by a system change using an inelastic thread, also in the Pendulum gear, is knitted.

At the thus provided with the substantially inelastic edge middle part is followed by a pendulum gear with the needles of the first needle group diametrically opposite second needle group knitted preferably elastic edge of the heel part. This edge consists of sub-mesh rows generated in the pendulum run in which, for example, an elastic thread is processed. Then the bag-like heel part is knitted at the edge with the needles of the second group of needles in the pendulum motion, for example by reducing stitches in a conventional manner for the production of a known wedge heel and then be increased again. After completion of the heel part with all needles of both groups of pins together in the round at least one round running row of stitches is created, which surrounds the opening of the heel bag and which is preferably designed as a Kettelmaschenreihe and may optionally be followed by some also knitted in concentric rows of drapes.

The thus-knitted blank is closed at the adjoining the heel part all-round row of stitches by a seam which extends transversely to the sole of the footlet and is arranged in the sole region.

The footlet according to the invention can, as already mentioned, be formed with an extremely large cutout, especially in the toe area, which is particularly desired when wearing the footlet in ballerinas. Due to its large neckline, the bootlet disappears completely in the shoe. In addition, the footlet is characterized by a very good fit. As experience has shown, unexpectedly large forces are needed to "drop" the bootlet over the heel in use, despite having a very large neckline. Since the edge of the footlet around the manhole in the manufacture of the blank, as explained, is knitted with, the confection of the edge required in many known feet can be omitted.

Further developments and further embodiments of the new footlet and the new method for its production are the subject of dependent claims.

In the drawing, an embodiment of the object of the invention is shown. Shown schematically in each case:

• FIG. 1 a bootlet according to the invention, in a plan view of the manhole,
• FIG. 2 following the footlet FIG. 1 in a top view on the sole,
• FIG. 3 a knitted blank for the production of feet FIG. 1 , in perspective view overlooking the manhole,
• FIG. 4 the blank after FIG. 3 , in perspective, with a view of the sole,
• FIG. 5 the blank after FIG. 3 in a side view and
• FIG. 6 a diagram illustrating the knitting process in the manufacture of a heel part with inverted reduction and increase of the foot after FIG. 1 ,

The in the FIGS. 1, 2 schematically represented from knitwear footlet has a bag or bag-like toe part 1 and this also opposite pocket or bag-like heel part 2 and between the Fußspitzen- and the heel part 1, 2 extending, the sole 3 containing middle part 4 on. The toe piece 1 is provided with a knitted elastic edge 5, which is followed by a likewise knitted, substantially inelastic edge 6 of the middle part 4, which is seamlessly connected to an elastic edge 7 which is knitted onto the heel piece 2. The toe piece 1, the heel part 2 and the middle part 4 define with their edges 5, 7, 6 the manhole 8 for the foot of the wearer of the footlet.

The toe piece 1 is bag-like or bag-like worked in a known manner by reducing and subsequent increase of stitches when knitting in the pendulum motion of the circular knitting machine, wherein the resulting abatement edges on the two sides of the manhole 8 are designated 9. The mitigation edges extend approximately from the edge 5 towards the toe. As in particular from FIG. 1 it can be seen that the toe piece 1 is knitted so that the footlet is formed with an extremely large cutout 10 in the front region of the manhole 8. This cutout 10 is essentially bounded by the elastic edge 5, which extends over an arc of about 180 ° and consists of some sub-stitch rows generated in the pendulum run, in which elastic thread material and / or rubber threads are contained.

In the area of the center part 4, which is also knitted in the pendulum gait, and which adjoins the toe part 1 seamlessly, the edge 6, which also consists of several rows of stitches, is essentially not elastic. In his courses Essentially, only one HE yarn (Helanca) is processed without EL (elastane) or rubber threads. The middle part 4 is knitted smooth and contains two mutually opposite incorporated markers 11, which serve as measuring points in quality control.

The seamlessly adjoining the middle part 4 heel part 2, is formed by reducing and increasing mesh bag-like. It may be designed in the manner of a known wedge heel, as described for example in "Albert Diebler, technology of circular knitting The circular knitting sock machine, Konradin Verlag". Alternatively, the bag-like heel part 2 can also be made with an "inverted" reduction and increase in stitches, as shown in FIG FIGS. 5, 6 will be explained below. The resulting mitigation lines or edges which extend from the edge 7 towards the sole 3 are in FIG FIG. 2 indicated at 12.

The first worked as an open bag heel part 2 is connected in the sole region with the central part by a transverse seam 13 which extends transversely to the sole 3 and is formed as Kettelnaht or Rosso seam or as a similar seam. The transverse seam 13 is located at the end of the sole part 3 at the transition from the middle part 4 to the heel part 2. As out FIG. 2 to see lead the two mitigation edges 12 to the transverse seam 13 out.

The elastic edge 7, which is knitted on the heel part 2 and extends over a circumference of 180 °, consists of a number of sub-stitch rows made in the pendulum run, in which an elastic thread, for example a rubber thread, is processed.

To the particularly large section at 10 of the footlet To be able to train without worsening the fit of the footlet, it is important to make the toe as elastic as possible and the heel as inelastic. Also, the upper edge of the footlet must not reach too far up. To meet these requirements, the transverse seam 13 is provided which lies in the region of the sole 3 and is an essential feature for the stabilization of the heel. Thus, the boundary of the footlet can be designed along the resulting optimal power line when wearing. Since the boundary of the access opening 8 composing the seamlessly adjoining edges 5, 7, 6 of the toe part 1, the middle part 4 and the heel part 2 consists of stitched stitches to the individual parts and is therefore also generated in the manufacture of the footlet, eliminates the need for certain known styles of feet confectioning the boundary.

• Der Füßling wird beginnend mit der Fußspitze zur Ferse hin gestrickt. Dazu wird zunächst der elastische Rand 5 des Fußspitzenteils 1 im Pendelgang mit den Nadeln einer ersten Nadelgruppe des Nadelzylinders der Rundstrickmaschine gestrickt, die sich etwa über einen Umfang von 180° des Nadelzylinders erstreckt und ca. die Hälfte der Nadeln des Nadelzylinders umfasst. Der elastische Rand besteht aus einigen im Pendelgang erzeugten Teilmaschenreihen, die Fangmaschen enthalten und in denen beispielsweise ein Gummifaden verarbeitet ist, um die Elastizität zu erzielen. An den Rand 5 anschließend wird mit den Nadeln der ersten Nadelgruppe das taschen- oder beutelartige Fußspitzenteil 1 im Pendelgang gestrickt, wobei die Herstellung des Beutels in an sich bekannter Weise durch Minderung und anschließende Zunahme von Maschen erfolgt, wobei die Minderungskanten 9 ausgebildet werden.

The footlet described above is made on a circular knitting machine provided with a means for reducing and increasing stitches. In principle, however, it can also be done on a flat knitting machine with two needle rows. The manufacturing process is described below with reference to FIGS. 3 to 6 explains in which with the FIGS. 1, 2 identical parts are provided with the same reference numerals:

• The footlet is knitted starting from the tip of the foot to the heel. For this purpose, first of all the elastic edge 5 of the toe piece 1 is knitted in pendulum motion with the needles of a first needle group of the needle cylinder of the circular knitting machine, which extends approximately over a circumference of 180 ° of the needle cylinder and comprises approximately half of the needles of the needle cylinder. The elastic edge consists of some sub-stitch rows generated in the pendulum run, the tuck stitches In which, for example, a rubber thread is processed to achieve the elasticity. Then, with the needles of the first group of needles, the bag-like or bag-shaped toe piece 1 is knitted at the edge 5 in pendulum motion, the bag being manufactured in a manner known per se by reducing and then increasing stitches, with the reduction edges 9 being formed.

The middle part 4 of a suitable yarn is knitted smoothly with the needles of the first group of needles in the pendulum run to the bag-like or bag-like toe piece 1 thus produced. In this case, at the same time the elastic edge 6 in the edge region of the central part 4 by appropriate knitting system change in the pendulum run with knitted. The edge 6 consists of several courses, in which, for example, helical thread is processed with tuck stitches.

The knitting operation is now continued with the knitting of the edge 7 which is knitted with needles of the second group of needles diametrically opposed to the needle cylinder of the circular knitting machine of the first group of needles. The edge 7 consists of several courses in which a rubber thread is incorporated, so that the edge 7 is elastic.

At the edge 7, if necessary, close some in the area 14 of FIG. 3 lying smooth rows of stitches, which are knitted with the needles of the second group of needles and optionally continue in courses of knitted by needles of the first group of needle stitches of the middle part 4, so that they form a total of some circular rows running. In any case, but after the knitting of the elastic edge 7 of the heel part 2 knits the heel part 2 in the form of a bag open on one side, which reduced mesh and then resumed. This heel bag may be knit in the form of a known wedge heel as shown in FIG FIG. 2 . 3 with the mitigation edges 12 is the case. The heel part 2 with the reduction and increase of the stitches is knitted in pendulum motion with the needles of the second group of needles and is therefore diametrically opposite the middle part 4 containing the sole 3, ie it is arranged rotated 180 ° on the needle cylinder with respect to the middle part.

After the completion of the bag-like heel part 2 is knitted at this at least one row of stitches in the circular run, which surrounds the opening of the heel bag and usually formed as Kettelreihe and in FIG. 3, 4 denoted by 15. At this round running at least one row of stitches 15 close some also knitted in concentric courses 16 as so-called rows of drains, which account for the later finished footlet.

The finished blank of the footlet is, like the FIGS. 3, 4 , show a substantially hose-like structure which is open on one side, in the region of the rows of stitches 15, 16 and which has an opening in the side of the access opening 8, which is surrounded by a boundary, which consists of the elastic edges 5, 7 and the inelastic edge 6 composed.

In a final operation, the tubular blank is closed along the Kettelmaschenreihe by the transverse to the sole 3 extending warp seam 13, wherein the rows of drains 16 are removed. As already explained, the transverse seam 13 formed as a warp seam runs, the can also be designed as a Rosso seam or otherwise, at the end of the sole 3 at the transition from the middle part 4 to the heel part 2, as can be seen from the FIG. 2 can be seen.

• Das Schaubild nach Figur 6 zeigt in einer Abwicklung die bei einem Zentriwinkel von 180° aufgeschnittene Schlauchware anschließend an den Rand 7 und die diesem folgenden Maschenreihen 14 des Rohlings nach Figur 3 unter Veranschaulichung der Maschenreihen des Randes 7 und der Maschenreihen 14, sowie der im Rundlauf gestrickten Kettelmaschenreihe 15 und der sich daran anschließenden Draufreihen 16 sowie der dazwischen liegenden, im Pendelgang von der zweiten Nadelgruppe erzeugten Teilmaschenreihen, die den Fersenbeutel des Fersenteils 2 bilden. Diese Teilmaschenreihen sind an ihren Enden miteinander unverstrickt dargestellt, um das Abnehmen (Mindern) und Aufnehmen (Zunehmen) der Maschen während der Herstellung des Fersenbeutels darzustellen. Während das Fußspitzenteil 1 und das Mittelteil 4, wie erläutert, mit einer ersten Nadelgruppe im Pendelgang gestrickt werden, die einen Umfangsbereich von etwa 270° bis 90° Zentriwinkel am Umfang des Nadelzylinders einnimmt, wird das Fersenteil 2 mit seinem Rand 7 und seiner Kettelnaht 15 sowie den Draufreihen 16 mit den Nadeln einer zweiten Nadelgruppe erzeugt, die den Nadeln der ersten Nadelgruppe gegenüber liegen und etwa einen Umfangsbereich zwischen 90° und 270° einnehmen. Diese Gradeinteilung längs um den Umfang des Nadelzylinders ist in Figur 6 oben angegeben. Das Schaubild veranschaulicht die aufeinander folgenden Maschenreihen schematisch jeweils durch horizontale Strichlinien.

Instead of a conventional wedge heel, the bag-like heel part 2 can also be knitted in a novel way with a so-called "inverted" reduction and increase of stitches. This embodiment is in the FIGS. 5, 6 illustrates:

• The graph after FIG. 6 shows in a settlement the cut open at a central angle of 180 ° tubular fabric then to the edge 7 and this following courses 14 of the blank after FIG. 3 illustrating the courses of the edge 7 and the rows of stitches 14, as well as the circular knitted Kettelmaschenreihe 15 and the adjoining rows of 16 and the intervening, generated in the pendulum course of the second needle group sub-mesh rows that form the heel bag of the heel part 2. These sub-mesh rows are shown undisplayed at their ends to illustrate the decrease (decrease) and containment (increase) of the stitches during the manufacture of the heel-bag. While the toe part 1 and the middle part 4, as explained, are knitted with a first group of needle pendulum, occupies a circumferential range of about 270 ° to 90 ° Zentriwinkel the circumference of the needle cylinder, the heel part 2 with its edge 7 and its Kettelnaht 15th and the rows of drawer 16 are generated with the needles of a second group of needles, which are opposite to the needles of the first group of needles and occupy approximately a circumferential range between 90 ° and 270 °. This graduation along the circumference of the needle cylinder is in FIG. 6 mentioned above. The diagram schematically illustrates the successive courses by horizontal dashed lines.

After knitting the rows of stitches 14 knitted in concentricity at the edge 7, the needles in the circumferential region between 270 ° and 90 ° are inactivated after reaching the last row of stitches 14a. With the then taking place in the pendulum course knitting with the remaining active needles in the peripheral region between 90 ° and 270 ° Teilmaschenreihen be prepared such that in the lying still outside the heel area 14a stitch row of Teilmaschenreihe or Teilmaschenreihengruppe 14b abruptly the number of stitches on a first minimum value is reduced. For this, the mesh size, as in FIG. 6 indicated by a dashed arrow 17, reduced to a first minimum value at 18, which corresponds in the illustrated embodiment, the needle number, which is approximately in the circumferential range between 158 ° and 202 °.

Starting from this first minimum value of the mesh number at 18, the number of stitches in each row of stitches is incremented one at a time or in rows of stitches in the rows of stitches subsequently knitted in the pendulum run, ie stitches are taken according to stitches until a row of stitches or course group 19 is reached which has a maximum Mesh size, which in the present case corresponds to the number of needles in the circumferential region between 90 ° and 270 °. This increase in the mesh number from the minimum value 18 to the maximum value 19 is in FIG. 6 indicated by an arrow 20.

In the further course of the knitting process taking place in the pendulum run, loops are again taken from the maximum value of the number of stitches in the course or courses at 19, as indicated by a dashed arrow 21 is indicated, until at 22 a second minimum value of the mesh number is reached, which corresponds to 18 in the selected embodiment of the first minimum number. After reaching the minimum number of stitches at 22, as indicated by an arrow 23, all stitches are taken up again at once, so that the initial state is achieved with all the needles lying in the circumferential range between 90 ° and 270 °. Then the concentricity of the machine is continued, that is, starting with the first lying outside the bag area circular circumferential row of stitches 15, which may be a Kettelmaschenreihe, the rows of lines 16 are knitted as a tubular fabric.

Compared to the conditions in a known wedge heel, the heel part 2 in the footlet according to the invention is thus characterized by an "inverted" reduction and increase. This style is, as in FIG. 5 indicated, the actual heel bag 3 free of mitigation edges, so that he can adapt very well to the anatomical shape of the heel, whereby an excellent fit of the boot is achieved. The reduction edges 12a run on both sides of the heel, as in FIG. 5 represented, on the edge of the actual heel bag. They each start from a common point 24 in the vicinity of the Kettelmaschenreihe 15 and include an angle 25 with each other, which is usually in the order of 75 ° to 90 °. From the point 24, the reduction edges 12a extend to the edge 7 and to the Kettelmaschenreihe 15, ie in the finished footlet to the transverse seam 13 out, like this FIG. 5 can be seen without further ado.

In an alternative embodiment, the bag-like heel piece 2 described can be used regardless of whether it is a wedge heel or with inverted reduction and increase the mesh is also knitted with the needles of the first group of needles subsequently to the middle part 4. This results in a tubular blank similar to that in FIG. 4 is shown, but with the difference that the knitted in the manner of an open bag heel part 2 is located on the side of the sole 3 of the middle part. The surrounding at the edge knurled with the second needle group 7 surrounding Kettelmaschenreihe 15, which may also be spaced by some intermediate circumferential rows 14 of the edge 7, then causes when closing the opening of the blank which extends transversely to the sole 3 Seam 13 is not in the sole area, but in the vicinity of the edge 7, that comes to rest in the upper part of the heel. Because of the intervening courses, the edge 7 would be compared to the embodiment according to FIG. 5 offset upwards.
