TECHNICAL FIELD The present invention describes a climate regulating stocking comprising a stocking foot with a sole area and a stocking length hose which extends along a lower leg area in the direction of a waist area, the stocking attaching at least one first knitting pattern and one attached to the at least one first knitting pattern Air conditioning duct, wherein the air conditioning duct runs on the inside and / or the outside of the stocking from the stocking foot to the lower leg area and is made from a second knitting pattern which is less densely knitted, comprises fewer stitches and / or has a lower basis weight than the first knitting pattern , as well as a method for producing a climate regulating stocking.

PRIOR ART [0002] The applicant has already described a climate regulating stocking 1 in EP 1 011 352, which is shown here in FIG. 1 to explain the prior art. The climate-regulating stocking 1 runs from a collar region 10 to a sole region 11 and forms a spatial textile structure which is closed to the sole region 11 and opened in the collar region 10. The stocking is formed at least by a first knitted fabric with at least one first knitting pattern 12, an air conditioning duct 2 with at least one second knitting pattern being arranged to run from the sole region 11 to the waist region 10.

The air conditioning duct 2 runs on an outer side of the stocking and an inner side of the stocking, symmetrically on both sides from the sole region 11 to the waist region 10. The air conditioning duct 2 is formed from a mesh knitted fabric as a second knitting pattern, which has a reduced contact surface and increased air permeability compared to the first knitted fabric. This configuration of the air conditioning duct 2 allows sweat moisture from the sole area 11 to be passed from a foot, which is in a shoe with the stocking 1 and the stocking 1 on, into an area of the stocking 1 in which free evaporation is possible. Such climate regulating stockings 2 are preferably used in sporting activities in which particularly robust and tight sports footwear is used and increased heat and perspiration are to be expected. Through the use of plastic yarns, preferably hollow-chamber plastic yarns, the moisture transport effect of the air conditioning duct 2 has been improved in recent years.

By exclusively made of synthetic fibers stockings 1 and other stocking zones in the form of climate-regulating pads, which comprise different materials and knitting patterns, the sweat transport, the evaporation but also the comfort of the stocking 1 could be further increased. The additional padding, however, led to a limited effect of the air conditioning duct 2. Functional socks of this type with a climate-regulating effect do not therefore achieve the desired, permanently guaranteed sweat transport if the stocking is worn for a long time and in higher shoes, for example in ski shoes or basketball shoes.

DESCRIPTION OF THE INVENTION The object of the present invention is to create a climate-regulating stocking, the climatic effect of which is further increased. The resulting climate-regulating stocking is produced in a corresponding knitting process, with no additional sewing or quilting steps being required. With cost-effective production on a knitting machine in just one knitting process, a stocking with an improved air-conditioning effect is achieved.

This problem is solved by a climate regulating stocking according to claim 1.

Further advantageous embodiments are listed in the dependent claims.

Description The climate-regulating stocking 1 presented here is knitted from a basic knitted fabric with a first knitting pattern 12 comprising at least one knitting yarn. The climate-regulating stocking 1 is essentially tubular and comprises a stocking foot S with a sole area 11 and a stocking length hose adjoining the stocking foot, which runs along a lower leg area U from the stocking foot S to a collar area 10.

The climate regulating stocking 1 extends overall from a sole area 11 on the stocking foot to a collar area 10, which adjoins the lower leg area U. The stocking 1 is preferably produced in one piece on a circular knitting machine in a continuous knitting process.

The first knitting pattern 12 and / or knitting yarns used in the waistband region 10, sole region 11, sock foot S and / or lower leg region U can differ from one another. The first knitting patterns 12 have a fine, elastically knitted and so dense structure that it provides sufficient stability and clings to the foot and lower leg of a wearer. The transition from the stocking foot S to the lower leg region U lies approximately at the height F of an ankle region or approximately the ankle bone (talus) of a wearer with the stocking 1 put on, which are identified by a dashed oval. When stocking 1 is put on, the ankle of a wearer's foot comes to lie at the level of the ankle area. The ankle area defines the transition from the stocking foot S to the lower leg area U or to the stocking length tube, which is formed by the lower leg area U and the collar area 10.

In the area of the ankle, along the shin and the calf of the wearer, increased support and stability is desired, which is why there are used accordingly tight first knitting patterns 12. For this purpose, stiffer knitting yarns or several layers of knitting patterns 12 can be stacked on top of one another and joined together for the first knitting pattern 12.

For the air-conditioning effect, an air conditioning duct 2 in the form of a main duct 20 is knitted onto the single- or multi-layer basic knitted fabric. Since the manufacturing process preferably takes place on a knitting machine, the basic knitted fabric and the main channel 20 are knitted and accordingly knitted together. The main channel 20 has a second, different knitting pattern than the basic knitting and / or a different knitting yarn composition than the basic knitting.

The main channel 20 extends at least from the ankle area, then to the stocking foot S from the end of the stocking foot or the height F of the strut of a wearer with the stocking 1 put on, along the lower leg area U of the stocking 1.

The second knitting pattern of the main channel 20 is preferably knitted less densely, comprising fewer stitches than the first knitting pattern 12. The stitch density is thus lower in the area of the main channel 20 than in the basic knitted fabric, which is preferably achieved by choosing a suitable knitting pattern. As a rule, the second knitting pattern also has less weight per surface and the air permeability and, depending on the second knitting pattern selected, also a different stretchability. The knitting pattern of the main channel 20 is referred to as a knitted mesh.

The first knitting pattern 12 of the basic knitted fabric is arranged in the course of the lower leg region U in the same position as the second knitting pattern of the main channel 20. The second knitting pattern of the main channel 20 can also be knitted by means of thinner knitting yarn compared to the knitting yarn of the basic knitting and therefore less dense than the first knitting pattern.

In the main channel 20, that is, in the area of the second knitting pattern, an increased vapor permeability for evaporating sweat results from the foot surface outwards through the climate-regulating stocking 1. Knitting technology makes it possible to produce knitted fabrics that have different functional areas. By

CH 714 663 A1 appropriate setting or programming of the knitting machines, the different areas can be created automatically in one knitting process.

Experiments have shown that the main channel 20 should taper in the course through the tubular lower leg region U in its course from the sole region 11 in the direction of the collar region 10. This improves the climate regulating effect. The main channel 20 tapers at least from an initial diameter D to a final diameter d at the end of the main channel 20 along the lower leg region U of the climate-regulating stocking 1. Initial diameter D and end diameter d are defined along the circumference of the climate-regulating stocking 1 and form straight sections of the main channel 20 between outer edges of the main channel at different heights. As shown here, the main channel 20 can end in front of the collar area 10. The taper of the main channel 20 extends to the end of the main channel 20, which has the final diameter d. The diameter of the main channel 20 thus tapers continuously from the initial diameter D to the smaller final diameter d.

The location at which the initial diameter D is determined is here the height F as the end of the stocking foot, before the start of the stocking length hose, which forms the lower leg region U. The end of the stocking foot and the beginning of the stocking length tube or lower leg region U is approximately at the level of the strut of the wearer when the stocking 1 is put on. The tapering of the main channel 20 is carried out approximately continuously, that is to say knitted in without steps.

It was recognized that, due to the tapering, the Bernoulli effect occurs in the main channel 20, which can also be estimated using the known Bernoulli theorem. Due to the different diameters or the narrowing of the diameters, the flow rate of the warm, moist air increases from the initial diameter D in the course to the final diameter d. The preferred ratio D / d should be greater than or equal to 1.5. Since the thickness of the knitted mesh, which forms the main channel 20, remains the same along the main channel 20, the cross-sectional area changes here due to the change in diameter.

Due to the increased speed of the humid heated air, the same together with moisture can be better discharged through the tapered main duct 20 than through the air conditioning duct known from the prior art. In the case of the air conditioning duct known from the prior art, it has not been recognized what constitutes a suitable shaping of the cross-sectional area of the air conditioning duct 2. As can be seen in FIG. 1 according to the prior art, the diameter of the air-conditioning duct was even increased on the way above the height of the stocking foot or ankle in the direction of the waistband region.

Due to the tapering of the main duct 20, which is preferably made from a mesh rope, moist and superheated air is pumped even faster than before with every movement of the foot when the stocking 1 is put on, even from a tight-fitting and tight-fitting shoe. The stocking 1 is thus able to remove warm and moist air and to supply the foot with cool, dry air, so that the foot can also “breathe” better in the shoe.

[0019] Main channels 20 are preferably arranged on the inside of the stocking and on the outside of the stocking. Particularly preferably, a connecting channel, not recognizable here, is made of knitted mesh, which continuously connects the main channels 20 on the inside and outside, in the area of the sole area 11, below the sole area. The main channel 20 along the inside and the main channel 20 'along the outside of the stocking 1 are additionally connected to one another below the stocking foot S by the connecting channel. Basically, there is therefore only one continuous main channel 20 which, starting from the sole area on the inside and outside, tapered in each case along the lower leg area U in the direction of its ends. The taper is defined in each case by the initial diameter D approximately at the level of the ankle and the course along the lower leg region U in the direction of the collar region 10 up to the final diameter d.

[0020] In an optimized embodiment, a plurality of branch channels 21 are knitted in, leading away from the main channel 20. The branch channels 21 are arranged in the course of the lower leg region U. The branch channels 21 also have a mesh knitting pattern, which is also more permeable to air than the basic knitted fabric. For the sake of simplicity, the knitting patterns or the knitting yarn of the main channel 20 and the branch channels 21 can be identical. The branch ducts 21 are usually oriented at branch angles α less than 90 ° to a longitudinal axis of the main duct 20. The branch channels 21 are thus arranged to lead away from the main channel 20 in the direction of the collar region 10. Since the tapering of the main duct 20 leads to a discharge of the moist, heated air at an increased speed, the branch ducts 21 can develop an additional discharge and thus an improved air-conditioning effect.

[0021] In addition, a branching channel 22 is knitted onto one or more of the branch channels in the course thereof. Here too, the branching channels 22 are arranged in the course of the lower leg region U along at least one branching channel 21. This branching channel 22 in turn has a knitted mesh or generally more breathable knitted fabric than the basic knitted fabric or first knitting pattern 12. The branching channels 22 are preferably arranged in the lower leg region U above half the stocking height h / 2 and particularly preferably at the level of the calves.

The region of the climate-regulating stocking 1 above half the stocking height h / 2 is even better ventilated and thus air-conditioned by the branching channels 22.

CH 714 663 A1 In order to optimize the air-guiding effect of the main duct 20 and / or the branch duct 21 and / or the branching duct 22, it can be provided in all embodiments to provide the side edges of the ducts with a duct edge bead 200. Such channel edge beads 200 can also be knitted during the knitting process, a thicker knitted fabric with an increased knitting yarn density and / or a thicker knitting yarn being used in the areas of the channel edge beads 200 than within the channels 20, 21, 22.

The climate regulating stockings 1 presented here can easily be provided with pads, in particular calf area pads, shin area pads, foot tension pads, toe area pads, ball area pads, heel area pads or Achilles tendon area pads. To do this, a corresponding marquetry pattern must be knitted on at the desired position of the upholstery during the knitting process. The person skilled in the art is familiar with the production of inlaid knitted fabrics and can program them on the same knitting machine. The inlays or the upholstery are created in a further knitted layer, on the basic knitted fabric or the layer with the first knitted pattern 12 and the knitted pattern of the channels 20, 21, 22. Since the tapered main duct 20 and the branching and branching ducts 21, 22 allow an optimal removal of the moist air, the cushions can at least partially cover the branching and branching ducts 21, 22.

5, a cushion 3 is shown using the example of a calf area cushion 3. This calf area cushion 3 lies in a knitted position above part of the branch channels 21 and the branching channels 22, which nevertheless still ensure adequate air conditioning.

Of course, a cushion 3 could also be arranged running in a knitted layer above the main channel 20, whereby the effect of the main channel 20 is retained.

The upholstery 3 are usually made of knitting yarn other than that used in the area of the basic knitted fabric or in the channels. The cushions are used on the various foot zones for mechanical protection, mechanical damping, thermal relief or thermal insulation.

By tapering the main channel 20, the speed at which the heated moist air is discharged can only be increased sufficiently that the branching and branching channels 21, 22 can have a sufficient effect below the cushions 3.

6 shows the superimposition of a first knitted layer, in which the basic knitted fabric 12 and branching channel 21 are located, and a second knitted layer, in which the cushion 3 is arranged, is shown. The knitted fabrics are arranged in a knitting process and connected to one another by stitch formation. The second layer of knitting in which the cushion 3 is located is arranged on the outside of the climate-regulating stocking 1 and points away from the foot of the wearer when the stocking 1 is pulled on. Heated moist air can be transported away through the branch duct 21 below the cushion 3.

In a further embodiment according to FIG. 7, a channel pad 23, the main channel 20 is arranged at least partially crossing in the longitudinal direction. The width of the channel pad 23 is made smaller than the width of the tapered main channel 20. In this embodiment, the channel pad 23 extends from the sole region 11 or from the connecting channel to the opposite tapered end of the main channel 20 with a final diameter d. In the embodiment according to FIG. 8, the channel cushion 23 is arranged to span only a part of the main channel 20. The at least one channel cushion 23 is preferably integrally formed in a non-detachable manner centrally on the main channel 20. In addition to a linear shape of the channel pad 23, the channel pad 23 can also be designed in a wave-like or curved manner and can be positioned along a section between the sole region 11 and the end of the main channel 20 on the collar side. The channel pad 23 is knitted in with an additional yarn when knitting the climate regulating stocking 1. The channel pad 23 preferably projects from the knitted layer of the main channel 20. The channel pad 23 prevents the material of the shoe from squeezing the main channel 20 too much when the climate-regulating stocking 1 is worn. As a result, more and better air can escape from the shoe. All of the variants of the climate-regulating stocking 1 described above can also have channel pads 23.

A possible composition for usable knitting yarns are mixtures of polyamide, polyester, polypropylene and elastane. Such a mixture can additionally be mixed with merino, silk and / or metallized polyamide.

In addition to climate-regulating hollow-chamber plastic yarns with enclosed air chambers, climate-active filaments with differently filled interiors are also used, which prevent bacterial growth and thus sweat odor.

From such compound yarn a moisture-absorbing and moisture-transporting mesh fabric is formed, which is arranged in the region of the channels. The skin is not completely covered in the area of the channels, so that drops of sweat can form on the skin of a foot, which then drip into the net and are transported away from there. This results in increased evaporative cooling or cooling.
