Definitions

  • the present invention relates to a knitted article, preferably a circular knit, according to the preamble of claim 1.
  • Such knitted parts are used in particular for the formation of arm or leg clothing, in particular socks, stockings or so-called sleeves.
  • These articles are also regularly used for compression therapy.
  • these articles have at least one, preferably several, compressive areas, which serve to exert targeted pressure on the body of a patient.
  • the pressure exerted on the body of a patient is referred to as compression.
  • the aim of such compressive articles, particularly in medical use is to relieve a patient's damaged venous and/or lymphatic system. The pressure applied prevents increasing swelling of the limbs, improves the removal of venous blood and lymph, and increases blood supply.
  • these compressive articles are used in sports, they increase performance and improve regeneration.
  • the RAL-GZ 387 of the quality mark association exists for the manufacture, in particular for the measurement and quality assurance, of, for example, compressive arm or leg stockings for medical use.
  • the RAL test regulations can be used to determine, for example, how the pressure of a compression stocking on a leg is to be determined.
  • the HoSy measuring device Hohenstein Institute
  • the test is carried out by measuring the tension at several measuring points, which varies depending on the respective extensibility of the knitted fabric, i.e. depending on the elasticity of the knitted fabric.
  • the compression is then calculated from the tension.
  • bandages are also known, e.g. in the form of ankle or knee joint bandages, which usually also consist of a tubular and preferably compressive knitted part.
  • a padding thread is usually incorporated into the basic knitted fabric made from a basic knitted thread.
  • Such a knitted part in particular a knitted leg garment with padding on the inside, in particular in the form of a compressive stocking, is known for example from EP 3 575 463 B1 known.
  • the leg garment is preferably designed as a stocking, leg warmer, leggings or pants and has padding on the inside, which is designed in such a way that it is arranged between the two muscle heads of the gastrocnemius muscle when the leg garment is worn.
  • the inside of the leg garment is thus partially offset inwards, as seen in the circumferential direction.
  • This at least one first padding also extends at least partially along the Achilles tendon when the leg garment is worn and overlaps it.
  • the leg garment preferably has at least one second padding which extends at least partially along the shin bone when the leg garment is worn and overlaps it.
  • a third padding is also provided for the toe area, the heel and/or the sole of the foot.
  • the first, second and third padding is preferably formed by a knitted section in the basic fabric, which differs in terms of its type of weave from an area adjacent to the padding.
  • the multiple paddings are preferably formed as a plush, in particular sandwich plush.
  • an additional plush thread is plated onto a basic knitted thread to form plush loops. These formed plush loops protrude from the fabric and form an additional layer of padding.
  • Another knitted part preferably also designed as a leg garment, is for example made of EP 3 375 921 A1 known.
  • the knitted part comprises two different plush handle shapes made of two separate plush threads, whereby the two plush handle shapes differ in their height.
  • the first layer or plane forms the basic knit.
  • the second layer or plane is formed by the shorter plush handles that protrude from the basic knit, while the third layer or plane is formed by the longer plush handles that protrude even further from the knit and also extend beyond the first plush handle plane. This can improve the cushioning or dampening properties of the knitted part.
  • the strength or thickness of the knitted fabric is significantly increased.
  • the plush loops or plush loops protrude far from the basic knitted fabric. This significantly improves the cushioning or damping properties of the knitted part, but this is unsatisfactory when taken into account and in relation to the increase in the knitted fabric thickness.
  • the reason for this is that the plush loops form gaps that have no effect on the cushioning or damping properties, but do have a significant influence on the knitted fabric thickness.
  • Another disadvantage is that the formation of the padding using a plush technique involves an enormous amount of thread and therefore material consumption.
  • the formation of the individual plush loops that protrude from the knitted fabric requires a multiple of the length of thread compared to the formation of a basic knitted stitch.
  • This means that this method of forming padding on a knitted piece is very cost-intensive, particularly due to the high material consumption, but also due to the associated long running times of the knitting machines. As a result, this type of padding is not very sustainable due to the large amount of resources used.
  • the formation of the padding using the plush knitting technique also has the disadvantage that it is susceptible to wear and tear.
  • the plush handles with the long loops, which are arranged on the left side of the fabric can easily be removed from the knitted fabric.
  • the right side of the fabric i.e. the outside of the knitted fabric, regularly suffers from unwanted pilling due to the loose binding of the plush thread, which is necessary to create plush loops. Pilling is the formation of small knots and lint. They are caused by loose fibers that have come loose from the knitted fabric due to friction.
  • the present invention is therefore based on the object of providing a knitted part which avoids the disadvantages of the prior art, in particular the cushioning property or the damping property of the knitted part and thus significantly improves the wearing comfort, preferably with a reduced knit thickness compared to the solutions known from the prior art.
  • the knitted part according to the invention in particular the circular knit, consists of at least one loop-forming basic knitting thread and at least one first and second plating thread, wherein the first plating thread is plated onto the basic knitting thread in the direction of the stitch rows to form a first cushioning layer at least in sections in the direction of the stitch rows and lies afloat over one or more basic knitting stitches formed by the basic knitting thread, and the second plating thread is plated onto the basic knitting thread or the first plating thread in the direction of the stitch rows to form at least a second cushioning layer at least in sections in the direction of the stitch rows and lies afloat over one or more stitches or floats formed by the first plating thread.
  • This forms a padded knitted part which consists of at least two cushioning layers.
  • the at least two cushioning layers are essentially formed by the individual and large number of floats of the first and second plating thread, which lie one above the other on the left-hand side of the knitted part, i.e. on the inside.
  • the individual floats of the first and second layers can each be seen as individual padding segments, which together create a flat padding.
  • the knitted part can of course also be produced as a flat knit on a flat knitting machine.
  • the at least one first and second plating thread are plated together on stitches formed by the basic knitting thread, forming stitches.
  • the thickness or strength of the knitted part in these places or stitches is only slightly changed or increased compared to the sections with the first and second padding layers.
  • the previously described stitches formed by the basic knitting thread, onto which the first and second plating threads are plated together to form stitches are arranged offset in the wale direction from stitch row to stitch row in the knitted part, preferably by an offset of one wale. This enables the formation of a ventilated padding with ventilation channels or profiles running obliquely to the wale direction.
  • At least one elastic weft thread is inserted into the stitches of the knitted part formed by the basic knitting thread via tuck and float and/or knitted with them to form stitches.
  • the number of consecutive stitches over which the second plating thread is floating is greater, preferably by one stitch, than the number of consecutive stitches over which the first plating thread is floating.
  • the length of the plurality of individual cushion segments is determined by the number of consecutive floats of the first and second plating threads.
  • the first plating thread is preferably floated over one stitch.
  • the second plating thread is preferably floated over two stitches.
  • the number of consecutive stitches over which the second plating thread is floated is particularly preferably between 2 and 10 stitches, preferably 2 to 6 stitches, for a knitting machine with up to 240 needles, and between 2 and 12 stitches, preferably also 2 to 6 stitches, for a knitting machine with more than 240 needles.
  • the at least one basic knitting thread and preferably the first plating thread consists of a moisture-transporting yarn and the second plating thread consists of a moisture-absorbing yarn.
  • the second plating thread preferably consists of several fibers with essentially round cross-sections, which thus ensure a large contact surface of the thread for contact with the skin of a wearer.
  • the at least one basic knitting thread and preferably the first plating thread preferably consist of several profile fibers spun together. The profile fibers, which have channels for transporting moisture, can therefore absorb and pass on the moisture from the second plating thread well.
  • the knitted part has a third plating thread, preferably a pattern or functional thread, which is plated at least in sections in the direction of the stitch rows onto the base knitting thread and/or the first plating thread and/or the second plating thread to form stitches and/or lies floating over these threads.
  • the pattern thread is preferably a different color than the other threads.
  • the functional thread is characterized, for example, by a special adhesive property. It can be made, for example, from silicone, elastane or rubber.
  • the multiple plating threads are only incorporated into the knitted part in sections in the direction of the stitch rows. Their ends are locked in the basic knitting stitches of the knitted part. The locking takes place by forming a stitch, with the thread ends protruding from the stitches formed by the basic knitting thread.
  • the base knitting thread and the plurality of plating threads consist of plastic, in particular polyamide, polyester or polyurethane, or of a natural fiber, in particular wool.
  • the at least one base knitting thread preferably has a fineness of 30 to 700 dtex
  • the plurality of plating threads preferably have a fineness of 30 to 300 dtex
  • the at least one weft thread preferably has a fineness of 200 dtex to 700 dtex.
  • the knitted part is particularly preferably a stocking, in particular an arm or leg stump, with or without a hand or foot part, a sock, a glove, a bandage, or a preferably compressive element of an orthosis.
  • the at least one first and second padding layer is preferably incorporated in a sole, calf, heel, toe and/or Achilles tendon area.
  • the compressive pressure values generated by the knitted part are between 5 and 60 mmHg, preferably between 10 and 45 mmHg, particularly preferably between 15 and 25 mmHg.
  • the compression values mentioned can be determined, especially for the compressive arm and leg stockings, using the measuring instructions and measuring method described at the beginning, in particular according to RAL-GZ 387 of the Quality Mark Association and using the HoSy measuring device (Hohenstein Institute).
  • This knitted item is characterized by a number of significant advantages.
  • the knitted part By forming the knitted part with at least two plating threads, which form a first and second padding layer, essentially due to the large number of floats of the first and second plating threads, an extremely flat padding with particularly high cushioning and damping properties is created.
  • This has the advantage that the padding, preferably on the inside of the knitted part, is not very bulky. This is particularly advantageous if the knitted part is designed as a piece of legwear, in particular as a stump with a foot part. Due to the low-bulk knitted fabric according to the invention, the fit of the wearer's foot in a shoe is only very slightly or not at all negatively affected, while at the same time the wearing comfort is improved by the formed padding, in particular by the multiple layers of padding.
  • a further advantage of the invention is the better adhesion of the padded knit to the skin of a wearer, for example to the sole of the foot. This is due to the fact that the knit according to the invention, in particular the large number of floats lying transversely to the knitting direction, means that a significantly increased amount of thread material, for example in comparison to a plush padding, comes to rest on the skin of the wearer.
  • the padded knitted part according to the invention is significantly less susceptible to wear, for example to so-called pilling, compared to the prior art, especially compared to a plush knit.
  • the plating threads for forming the padding are in fact much tighter and firmer and are also worked more closely into the stitches of the basic knit. There are therefore no loops, handles or loops that protrude from the knit and are therefore susceptible to wear, as is the case in particular when forming a plush knit.
  • Another significant advantage over the known solutions is the significantly better climate and moisture management of the knitted part.
  • the padding especially the first and second padding layers, using a large number of floats, significantly less thread material is used to form the padding.
  • the padded knit allows for better air circulation.
  • the channels preferably formed additionally on the knitted part or in the padding, support this circulation even more.
  • significantly less moisture can be stored in the thread material itself. Fewer gaps are also formed in which moisture can collect.
  • Another advantage is that the significantly reduced thread consumption makes the padding much more cost-effective to produce. This is due to the reduced material consumption, but also due to the significantly shorter machine running time required to form the padding according to the invention on the knitted part. This new way of forming padding on a knitted part is therefore also much more sustainable than the solutions known from the prior art.
  • padding with two layers of padding in addition to the advantage of significantly improved padding and damping properties, also has the advantage that padding with individual padding thicknesses can be formed. This means that padding can be adapted to specific areas and individually to the needs within the knitted part.
  • multi-dimensional structures can be formed, e.g. recesses or elevations to form channels for air circulation or ribs, especially for massage purposes.
  • the knitted part 1 is designed as a calf sock 16.
  • this comprises a compressive leg part 21, preferably provided with a gradual pressure gradient.
  • the compressive pressure preferably decreases from distal to proximal.
  • the foot part 20 has a toe area 25, a midfoot area 27, a heel area 24 and an area 28 surrounding the ankle. It is also possible for the toe area 25 to be open.
  • the leg part 21 in turn has a waistband section 29 at its upper end, which is preferably designed as a double-layered waistband.
  • the stump 16 preferably consists of a round or flat-knitted, preferably compressive, knitted part 1.
  • the compressive pressures generated by the calf stocking 16 are preferably between 10 and 30 mmHg in the ankle area 30 and between 5 and 20 mmHg in the calf area 23.
  • the values are measured using the measuring method and measuring device presented at the beginning, in particular by testing on the HoSy measuring device (Hohenstein Institute).
  • the knitted part 1, in particular the foot part 20, has a padding 9 consisting of a first and second padding layer 10, 11.
  • the padding 9 extends in the foot part 20 from the metatarsal region 27 to the heel region 24. Furthermore, the padding 9 then continues in the leg part 21 and overlaps an Achilles tendon region 26 there.
  • the padding 9 extends in both the foot part 20 and the leg part 21 only in sections around the foot or leg of a wearer in the circumferential direction. This is therefore preferably only formed in the area of the sole of the foot 22 and the Achilles tendon and in this embodiment extends into the sides of the foot part 20 and leg part 21.
  • the padding 9 is preferably formed by a knitted fabric 1, which differs in terms of its weave from an area adjacent to the padding 9.
  • a knitted fabric 1 which differs in terms of its weave from an area adjacent to the padding 9.
  • FIG. 2 The structure of the padding 9, particularly in the area of the sole of the foot 22, is now described in detail.
  • a stitch pattern of the knitted part 1 is shown in section A.

  • the first plating thread 3 in each knitting row R1 to R7 is plated onto the basic knitting thread 2 in the first and ninth wales M1 and M9 to form stitches and floats over the stitches in between.
  • the plating i.e. the formation of stitches 4, of the first plating thread 3 in the wales M1 and M9 on the basic knitting thread 2 serves to anchor or connect the first padding layer 10 to the basic knitting 1.
  • the second plating thread 6, however, is plated onto the basic knitting thread 2 in the fifth wale M5 in each knitting row R1 to R7, thus forming stitches 7 there. Since the stitch pattern is only a section A of the basic knitted fabric 1, the second location, i.e. the further wale, in which the second plating thread 6 is plated onto the basic knitting thread 2 to form stitches, cannot be seen. However, here too, the second plating thread 6 is preferably floated over seven stitches in order to form second cushion segments of a second cushion layer 11 with a length of seven floats 8. The number of consecutive stitches 12 over which the at least one first and second plating thread 3, 6 is floated can of course be individually determined. In a knitting machine with up to 240 needles, a float of between 1 and 10 stitches is preferably used. For a knitting machine with more than 240 needles, the float length is preferably between 1 and 12 stitches.

  • Both threads 3, 6 are therefore floated over the wales M2 to M4 and M6 to M8 and thereby form cushion segments for the first and second cushion layers 10', 11' with a length of three floats 5, 8.
  • the number of consecutive stitches 12 over which the two plating threads 3, 6 are floated can of course also be individually determined in this embodiment.
  • the advantage of this design of the knitted part 1', in particular the padding is that by plating the first and second plating threads 3, 6 together on common basic knitting stitches 12, in addition to the multiple padding layers 10', 11', several recesses or channels 40 are also created on the inside of the knitted part 1'. These serve in particular for ventilation of the knitted part 1' or the padding 9'.
  • the recesses or channels 40 are created by the joint plating of both threads 3, 6 onto common stitches 12. This means that the thickness or strength of the knitted part 1' is not changed or only insignificantly changed in these stitches 12, since the plating threads 3, 6 in these stitches 12 do not lie above the basic knitting stitches 12, but essentially only next to these stitches 12. In contrast, the floats 5, 8 lie outside and thus above the basic knitting stitches 12 and thus form a first and second cushion layer 10', 11'. This results in a three-layer or three-layer structure with preferably several recesses 40.

Of course, it is also conceivable that these extend transversely to the sole of the foot 42. These elevations 48 give the knitted part 1" a local massaging effect. In the next Figure 6 the knitted part 1", in particular the padding 9" with the several elevations 48 through the cutout C, is described in detail using a stitch pattern.
  • a basic knitting thread 2 is knitted over several knitting rows R1 to R7 and wales M1 to M9 to form stitches.
  • a further thread namely an elastic weft thread 13 is inserted into the stitches 12 of the knitted part 1" formed by the basic knitting thread 2 via tuck 14 and float 15.

  • the compressive pressure values generated by the knitted part 1" are therefore between 5 and 60 mmHg, preferably between 10 and 45 mmHg, preferably in an ankle area 47, but also in the area of the padding 9", i.e. in a metatarsal area 42.
  • Figure 7 finally shows a fourth embodiment of the knitted part 1′′′ according to the invention designed as a bandage 19 or as a so-called sleeve, in particular for use on a wearer's knee, also in a side view.
  • the preferably compressive knee bandage 19 shown consists essentially of a thigh part 49 and a lower leg part 50. Both parts enclose a patellar area. At the upper and lower ends, the bandage 19 also has a closing edge 51 and 52.
  • the knee bandage 19 serves to stabilize the joint.
  • the bandage 19 preferably consists of the tubular and compressive knitted part 1′′′. In addition to the knitted part 1′′′, the bandage 19 preferably has a knee pad (not shown).
  • a separate pad can also be provided, which can be positioned on the wearer's knee independently of the knitted part 1′′′.
  • the pad preferably has an adhesive layer on the side facing the wearer when worn. This self-adhesive surface allows the pad to adhere to the wearer's skin without external help.
  • the knitted part 1′′′ now also has a padding 9′′′ on the inside with a first and second padding layer 10′′′, 11′′′.
  • the padding 9′′′ extends in the longitudinal direction over the entire length of the bandage 19, i.e. over the lower and thigh parts 49, 50. Also in the circumferential direction, the padding 9′′′ is formed over the entire circumference on the inside of the knitted part 1′′′.
  • the entire knee bandage 19, i.e. the entire inside is provided with the padding 9′′′.
  • the padding 9′′′ on the inside again forms several channels 53 for ventilation of the knitted fabric 1′′′ or the padding 9′′′.
  • These ventilation channels 43 now run obliquely to the longitudinal extension of the bandage 19 and thus also obliquely to the wale direction MR of the basic knitted fabric 1′′′.
  • the knitted part 1′′′ in particular the structure of the padding 9′′′ with the several channels 48, is explained in detail in a section D.
  • the stitch pattern from Figure 8 shows a basic knitting thread 2 which is knitted over several knitting rows R1 to R7 and wales M1 to M9.
  • two plating threads 3, 6 are also plated onto the basic knitting thread 2 to form stitches 4, 7 and floated over it to form a first and second cushioning layer 10′′′, 11′′′.
  • the first and second plating threads 3, 6 in the stitch row R7 in the second and sixth wales M2 and M6 are plated onto the basic knitting thread 2 to form stitches. Between these stitches M2 and M6, both plating threads 3, 6 lie floated over the basic knitting stitches 12 formed between them. They therefore form cushioning segments of a first and second cushioning layer 10′′′, 11′′′ with a length of three floats 5, 8.
  • a second stitch row R2 the stitches M4 and M8 from row R1, on which both the first and the second plating thread are plated in a stitch-forming manner, are arranged offset by one wale in the knitted part 1′′′. These stitches are thus located in the stitch row R2 at the positions M3 and M7. This offset, which continues in the following stitch rows R3 to R7, forms a padding which has several ventilation channels 53 running obliquely to the wale direction MR.
  • FIG 9 finally shows another stitch pattern of another possible embodiment of the knitted part 1 ⁇ according to the invention.
  • a basic knitting thread 2 is again knitted over several knitting rows R1 to R7 and wales M1 to M7.
  • an elastic weft thread 13 is inserted into the stitches 12 of the knitted part 1 ⁇ formed by the basic knitting thread 2 over the tuck 14 and float 15.
  • a first plating thread 3 is now worked into each knitting row R1 to R7.
  • the plating thread 3 is in the first, third, fourth, sixth and seventh wales M1, M3, M4, M6 and M7 are plated onto the basic knitting thread 2 to form stitches and lie floating over the stitches in between. It is therefore floated over the wales M2 and M5 and thus forms cushion segments of a first cushion layer with a length of one float 5.
  • the second plating thread 6 is also present in each knitting row R1 to R7.
  • this is plated onto the basic knitting thread 2 in the first, fourth and seventh wales M1, M4 and M7 to form stitches.
  • This is floated over the wales M2 and M3 as well as M5 and M6 to form second cushioning segments of a second cushioning layer 11 ⁇ with a length of two floats 8.
  • the number of consecutive stitches 12 over which the second plating thread 6 lies floats is therefore greater than the number of consecutive stitches 12 over which the first plating thread 3 lies floats. This has the advantage that it ensures that the second plating thread 6 always comes to lie above the first plating thread 3.
  • both plating threads 3, 6 are plated onto common stitches 12, this padding 9 ⁇ also forms a plurality of recesses or channels 54 on the inside of the knitted part 1 ⁇ , which serve to ventilate the knitted part 1 ⁇ or the padding 9 ⁇ .
  • the plurality of stitches on which the first and/or the second plating thread 3, 6 is plated to form a stitch are arranged offset by one stitch wale in the wale direction MS in the knitted part 1 ⁇ , a padding 9 ⁇ is also formed in this embodiment, with the plurality of ventilation channels 54 running obliquely to the wale direction MR.
  • the invention is not limited to the described embodiments, but includes all embodiments that apply or contain the basic, analogous functional principle of the invention. Furthermore, all features of all described and illustrated embodiments can be combined with one another.
