Description

Climate-regulating stocking

Technical area

The present invention describes a climate regulating stocking comprising a stocking foot having a sole region and a stocking length tube extending along a lower leg region towards a waistband region, the stocking having at least a first knit pattern and an air conditioning channel attached to the at least one first knit pattern Climatization channel on the inside and / or the outside of the stocking from the stocking foot to the lower leg area and is made of a second knit pattern, which is less dense knit, comprises fewer stitches and / or has a lower basis weight than the first knit pattern, and a method for Production of a climate regulating stocking.

State of the art

The applicant has already described in EP1011352 a climate-regulating stocking 1, which is shown here in FIG. 1 for explaining the state of the art. The climate-regulating sock 1 runs from a waistband region 10 to a sole region 11 and forms a closed-to-sole region 11 and open in the waistband region 10 spatial textile structure. The sock is at least formed by a first knit fabric having at least one first knit pattern 12, wherein an air conditioning duct 2 having at least one second knit pattern extending from the sole region 11 to the waistband region 10 is arranged.

The air conditioning duct 2 runs on a hosiery outside and a hosiery inside, symmetrically on both sides of the sole region 11 to the waistband 10. The air conditioning channel 2 is formed of a net knit as a second knitting pattern, which has a reduced contact surface and increased air permeability compared to the first knit fabric. Due to this design of the air conditioning duct 2 can moisture from the

Sole region 11 of a foot, which is in a shoe with tightened stocking 1 including stocking 1, are directed into a region of the stocking 1, in which a free evaporation is possible. Such climate-regulating stockings 2 are preferably used in sports activities in which usually particularly robust and dense sports footwear is used and can be expected with increased heat and sweat. Through the use of plastic yarns, preferably hollow-chamber plastic yarns, the moisture transporting 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 upholstery, which include different materials and knitting patterns, the Schweisstransport, the evaporation but also the wearing comfort of the stocking 1 could be further increased. However, the additional pads led to a limited effect of the air conditioning channel 2. Such functional socks with klimegulierender effect, therefore reach not the desired permanently guaranteed Schweisstransport when the stocking is worn for a long time and in higher shoes, for example in ski boots or basketball shoes.

Presentation of the invention

The present invention has set itself the task of creating a climate-regulating stocking whose air conditioning effect is further enhanced. The resulting climate-regulating Stocking is produced in a corresponding knitting process, wherein is dispensed with additional sewing or stitching steps. With cost-effective production on a knitting machine in only one knitting process, a stocking with improved air conditioning effect is achieved.

This object is achieved by a climate regulating sock 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 knit with a first knit pattern 12 comprising at least one knitting yarn. The climate-regulating stocking 1 has a substantially tubular shape and comprises a stocking foot S with a sole region 11 and a stocking hose which adjoins the stocking foot and extends along a lower leg region U away from the stocking foot S to a waistband region 10.

Overall, the climate-regulating stocking 1 extends from a sole region 11 on the stocking foot to a waistband region 10, which adjoins the lower leg region U. The production of the stocking 1 preferably takes place on a circular knitting machine in a continuous knitting process in one piece.

The first knitting patterns 12 and / or knitting yarns used in the waistband region 10, sole region 11, stocking foot S and / or lower leg region U may differ from one another. The first knitting patterns 12 have a fine, elastically knitted and dense structure such that it provides sufficient stability and conforms to the foot and lower leg of a wearer. The transition from the stocking foot S to the lower leg area U lies approximately at the height F of an ankle area or about the ankle bone (talus) of a wearer with the stocking 1 put on, which are marked with a dashed oval. When the stocking 1 is put on, the ankle joint of the wearer's foot comes to rest at the level of the ankle region. Here, the ankle region defines the transition from the stocking foot S to the lower leg region U or to the hosiery hose, which is formed by the lower leg region U and the waistband region 10. In the area of the ankle, along the tibia and the calf of the wearer, increased support and stability is desired, which is why correspondingly close-meshed first knit patterns 12 are used there. For this purpose, stiffer knitting yarns or a plurality of layers of knit patterns 12 may be stacked on top of each other for first knitting patterns 12 and used together.

For the air-conditioning effect, an air-conditioning duct 2 in the form of a main duct 20 is knitted here on a single- or multi-ply basic knit. Since the production process preferably takes place on a knitting machine, basic knitted fabric and main channel 20 are each knitted and knit together correspondingly. In this case, the main channel 20 has a second, different knitting pattern than the basic knitting and / or a different knitting yarn composition than the basic knit.

The main channel 20 extends at least from the region of the ankle, adjoining the stocking foot S, following the end of the stocking foot or the height F of the anklebone of a wearer while the sock 1 is pulled up along the lower leg portion U of the stocking 1.

Preferably, the second knitting pattern of the main channel 20 is less densely knitted, comprising fewer stitches than the first knitting pattern 12 is made. The mesh density is thus lower in the region of the main channel 20 than in the basic knit, which is preferably achieved by selecting a suitable knit pattern. The second knitting pattern usually also has less weight per area and the air permeability and depending on the selected second knit pattern also a different stretchability. The knitting pattern of the main channel 20 is referred to as net knit.

The first knit pattern 12 of the basic knit is arranged in the same position in the course of the lower leg area U as the second knit pattern of the main channel 20. The second knit pattern of the Main channel 20 may also be knitted using a thinner knitting yarn, compared to the knitting yarn of the basic knit, and thereby made less dense than the first knitting pattern.

In the main channel 20, ie in the region of the second knit pattern, an increased vapor permeability for evaporating perspiration results from the foot surface to the outside through the climate-regulating stocking 1. By knitting technique, it is possible to produce knitted fabric having different functional areas. By appropriate adjustment or programming of the knitting machines, the different areas can be created automatically in a knitting process.

Experiments have shown that the main channel 20 should be tapered in the course of the tubular lower leg region U in its course from the sole region 11 towards the waistband region 10. The climate-regulating effect is thereby improved. 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 final diameter d are defined along the circumference of the climate regulating stocking 1 and constitute straight sections of the main channel 20 between outer edges of the main channel at different heights. As shown here, the main channel 20 may terminate in front of the waistband 10. The taper of the main channel 20 extends to the end of the main channel 20, which has the final diameter d. Thus, the diameter of the main channel 20 tapers steadily from the initial diameter D to the smaller end 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 beginning of the stocking hose which forms the lower leg area U. The End of the stocking foot and the beginning of the stocking hose or lower leg area U is located at tightened sock 1 approximately at the level of the ankle of the wearer. The taper of the main channel 20 is carried out approximately continuously, so knitted stepless.

It has been recognized that due to the rejuvenation, the Bernoulli effect occurs in the main channel 20, which can also be estimated using the well-known Bernoulli's theorem. Due to the different diameters or the tapering 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 net knit, which forms the main channel 20 along the main channel 20 remains the same, here the cross-sectional area changes due to the change in diameter.

Due to the increased speed of the moist, heated air, the same, together with moisture, can be better dissipated through the tapered main channel 20 than through the air-conditioning channel 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 Figure 1 according to the prior art, even the diameter of the air conditioning channel on the way above the height of the stocking foot or ankle in the direction of waistband area was even increased.

Due to the tapering of the main channel 20, preferably made of a net knit, moist and superheated air is pumped even faster than before, even when the foot is tightened with the stocking 1 put on, even from a tight and tight fitting shoe. The stocking 1 is thus able to dissipate warm and moist air and the Provide the foot with cool, dry air so that the foot can also "breathe" better in the shoe.

Preferably, main channels 20 are arranged on the inner side of the stocking and the outside of the stocking. Particularly preferred is a connection channel which is not recognizable here and which is made of mesh fabric, which in the region of the sole region 11 continuously connects the main channels 20 on the inside and the outside, below the sole region. In each case, the main channel 20 along the inside and the main channel 20 'along the outside of the sock 1 are additionally connected to each other below the stocking foot S through the connecting channel. Basically, therefore, only one continuous main channel 20 is present, which, starting from the sole region on the inner side and the outer side in each case along the lower leg region U tapers in each case in the direction of its ends. The taper is in each case defined by the initial diameter D approximately at the level of the ankle and the course along the lower leg area U in the direction of the waist region 10 to the final diameter d.

In an optimized embodiment, a plurality of branch channels 21 are knitted away from the main channel 20. The branch channels 21 are arranged in the course of the lower leg area U. The branch channels 21 likewise have a net knitting pattern, which is also more permeable to air than the basic knit fabric. For simplicity, the knitting yarns of the main channel 20 and the branch channels 21 may be identical. Usually, the branch channels 21 are aligned at branching angles a smaller than 90 ° to a longitudinal axis of the main channel 20. Thus, the branch channels 21 are arranged leading away from the main channel 20 in the direction of the waist region 10. Since the taper of the main channel 20 leads to a discharge of the moist heated air at an increased speed, the Abzweigungskanäle 21 develop an additional discharge and thus improved air conditioning effect.

In addition, a branching channel 22 is knitted on one or more of the branch channels in the course thereof. Here, too, the branching channels 22 are arranged along at least one branch channel 21 in the course of the lower leg region U. This branching channel 22 in turn has a mesh or generally air-permeable knitted fabric, as the basic knit or first

Knitted pattern 12 on. The branching channels 22 are preferably arranged in the lower leg region U above half the hosiery height h / 2 and particularly preferably at the level of the calves.

Through the branching channels 22, the area of the climate-regulating sock 1 above the hosiery h / 2 is even better ventilated and thus air-conditioned.

In order to optimize the air-guiding action of the main channel 20 and / or the branch channel 21 and / or the branching channel 22, it may be provided in all embodiments to provide the side edges of the channels with a channel edge bead 200. Such channel edge beads 200 are also during the

Knitting knit produced, wherein in the areas of the channel edge bead 200 a denser knitted fabric with an increased Strickgarndichte and / or a thicker knitting yarn, than within the channels 20, 21, 22 is used.

The climate-regulating stockings 1 presented here can be easily fitted with upholstery, especially calf area cushions,

Tibia area pad, foot pad, toe pad, bale area pad, heel area pad or

Achilles tendon area pads are provided. This is a corresponding intarsia pattern during the knitting process at the desired position of the pad. The person skilled in the production of intarsia knits is known he can program them on the same knitting machine. The inlays or the upholstery are created in a further knitting position, on the basic knit or the layer with the first knit pattern 12 and the knitting pattern of the channels 20, 21, 22. Because the main tapered channel 20 and the branching and branching channels 21, 22 allow for optimized removal of the moist air, the pads may at least partially cover the branching and branching channels 21, 22.

FIG. 5 shows a cushion 3 using the example of a calf area pad 3. This calf area pad 3 is located in a knitting position above a portion of the branch channels 21 and the branch channels 22, which still ensure adequate air conditioning.

Of course, a pad 3 could be arranged extending in a knitting position above the main channel 20, whereby the effect of the main channel 20 is maintained.

The pads 3 are usually made of other knitting yarn than in the basic knit or in the channels made. The upholstery serves at the different foot zones for mechanical protection, mechanical damping, thermal relief or thermal insulation.

By the taper of the main channel 20, the speed at which the heated moist air is removed, only be sufficiently increased so that the Abzweigungs- and branching channels 21, 22 can develop a sufficient effect below cushions 3.

In the sectional view according to FIG. 6, the superimposition of a first knitting layer in which basic knit 12 and branch channel 21 are located and a second knit layer in which the upholstery 3 is located is arranged, shown. The knitted fabrics are arranged in a knitting process and connected to each other by stitching. The second knitting layer in which the pad 3 is located, is arranged on the outside of the climate-regulating sock 1 and has in the tightened state of the sock 1 away from the foot of the wearer. Heated moist air can be transported away through the branch channel 21 below the pad 3.

In a further embodiment according to FIG. 7, a channel pad 23, the main channel 20, is arranged at least partially transversely 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 and the connecting channel to the opposite tapered end of the main channel 20 with the final diameter d. In the embodiment according to FIG. 8, the channel cushion 23 is arranged spanning only a part of the main channel 20. Preferably, the at least one channel pad 23 is integrally formed centrally on the main channel 20 inextricably. In addition to a rectilinear shaping of the channel pad 23, the channel pad 23 can also be embodied wave-like or curved and positioned along a section between the sole region 11 and the collar-side end of the main channel 20. The channel pad 23 is knitted by an additional yarn when knitting the climate-regulating sock 1 with. The channel pad 23 preferably depends on the knitting position of the main channel 20. By the channel pad 23 prevents the wear of the climate-regulating sock 1, the material of the shoe squeezes the main channel 20 too much. As a result, more and better air can escape from the shoe. All variants of the climate-regulating sock 1 described above can also have channel padding 23. A possible composition for knitting yarns which can be used are blends of polyamide, polyester, polypropylene and elastane. Such a mixture may additionally be mixed with merino, silk and / or metallized polyamide.

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

From such compound yarn creates a moisture-absorbing and moisture-transporting mesh fabric, which is arranged in the region of the channels. The skin in the area of the channels is not completely covered, 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 creates an increased evaporation cooling or cooling.
