Abstract

A climate-adjusting stocking (1) comprising a sole (S) with a sole region (11) and a stocking tube extending along a shank region (U) to a joining region (10), wherein the stocking (1) has at least a first weave pattern (12) and a climate-adjusting tube (2) which is fixed at least to the first weave pattern (12), wherein the climate-adjusting tube (2) on the inner and/or outer side of the stocking (1) extends from the sole (S) to the shank region (U) and is made of a second weave pattern which is less compact, has fewer meshes and/or has a smaller weight per unit area than the first weave pattern (12), whereby the climate-adjusting effect is improved. This is achieved by the main conduit (20) being connected to the first weave pattern (12) by a second weave pattern such that the main conduit (20) tapers continuously from an initial diameter (D) towards the longitudinal axis of the main conduit (20) starting at the sole (S) end height (F) of the calf region (U) along the long stocking until a smaller end diameter (D) is formed.

Description

Climate-adjusting stocking

Technical Field

The invention relates to a climate-controlled stocking comprising a sole region and a stocking sole, which extends along a shank region to a joining region, wherein the stocking has at least a first knitting pattern and a climate control tube which is fastened at least to the first knitting pattern, wherein the climate control tube on the inside and/or on the outside of the stocking extends from the sole to the shank region and is made of a second knitting pattern which is less compact, has fewer meshes and/or has a smaller weight per unit area than the first knitting pattern, and to a method for producing a climate-controlled stocking.

Background

The applicant has described in EP1011352 a climate adjusting stocking 1, which stocking is shown in fig. 1 to illustrate the state of the art. The climate-adjusting stocking 1 extends from the joining region 10 to the sole region 11 and forms a spatial textile structure which is closed towards the sole region 11 and which is open in the joining region 10. The stocking consists of a first knitted fabric with at least a first knitting pattern 12, wherein a climate control tube 2 is provided, which has at least a second knitting pattern extending from the sole area 11 to the joining area 10.

The climate-control duct 2 extends on the outside and inside of the stocking and is symmetrical on both sides from the sole region 11 to the joining region 10. The climate control duct 2 is formed from a knitted net in a second knitting pattern, which has a smaller contact surface and a higher air permeability than the first knitted fabric. By this design of the climate control duct 2, the foot perspiration in the sole region 11 can be introduced into the region of the stocking 1 and then can evaporate freely when the stocking 1 is put on, including when the stocking 1 is inserted into a shoe. Such climate-adjusting stockings 2 are preferably used in sporting activities, wherein particularly strong and compact athletic shoes are typically used and heat and perspiration are increased. In recent years, the perspiration effect of the climate tube 2 has been improved by the use of a glue yarn, preferably a hollow glue yarn.

By using a stocking 1 made of synthetic fibers only and other areas of the stocking of the climate control pad type comprising different materials and weave patterns, perspiration, evaporation and wearing comfort of the stocking 1 can be further improved. However, the additional cushion can only fulfil a limited function of the climate control duct 2. Thus, if long wear of stockings and high-waist shoes, such as skiing shoes or basketball shoes, is performed, such functional socks with climate adjusting effect cannot achieve the desired lasting perspiration effect.

Disclosure of Invention

The object of the present invention is to provide a climate-regulating stocking, the climate-regulating effect of which is further enhanced. Such climate control stockings are produced by a corresponding braiding process, wherein no additional sewing or stitching steps are required.

By means of only one knitting process and a low cost production on the knitting machine, a stocking with improved climate control can be produced. This object is achieved by a climate-adjusting stocking as claimed in claim 1. Other advantageous designs are set forth in the dependent claims.

Detailed Description

The climate control stocking 1 described here is knitted from a basic knitted fabric with a first knitting pattern 12, comprising at least one yarn. In general, the climate-adjusting stocking 1 is tubular and comprises a sole S with a sole region 11 and a stocking tube connected to the sole, which stocking tube extends along a calf region U from the sole S to a joining region 10.

In general, the climate-adjusting stocking 1 extends from a sole region 11 of the sole to a joining region 10 which connects the calf region U. The production of the stocking 1 is preferably carried out in one piece in a continuous knitting process on a circular knitting machine.

The first weave pattern 12 and/or the yarns used in the joining region 10, the sole region 11, the sole S and/or the calf region U may be different. The first weave pattern 12 has a tight fine elastic weave structure to provide adequate stability and fit against the wearer's foot and lower leg. When the stocking 1 is worn, the transition from the sole S to the calf region U is located approximately in the ankle joint region or approximately at the height F of the ankle bones (talus) of the wearer, indicated by the oval dashed line. When the stocking 1 is worn, the ankle joint of the wearer is located at the level of the ankle joint region. The ankle joint area defines the transition from the sole S to the calf area U or to the long tube of the stocking, which is formed by the calf area U and the joining area 10.

In the region of the foot joint, it is desirable to increase support and stability along the tibia and calf of the wearer, so that a first weave pattern 12 with correspondingly tight mesh is used herein. Wherein for the first weave pattern 12, a stiffer yarn or multiple layers of weave patterns 12 are used that overlap and are connected to each other.

In order to obtain a climate control effect, the climate control tube 2 is woven in the form of a main tube 20 onto a single-layer or multi-layer basic knitted fabric. Since the production process is preferably carried out on a knitting machine, the basic knitted fabric and the main line 20 are knitted separately and connected to each other in a knitted manner. The main line 20 has a second weave pattern different from the base knit and/or a different weave yarn composition than the base knit.

The main line 20 extends at least from the ankle joint area near the sole S, along the calf area U of the stocking 1, from the end of the sole when the stocking 1 is worn or from the height F of the wearer' S ankle.

Preferably, the second weave pattern of main conduit 20 has a weave density less than the weave density of first weave pattern 12, with fewer meshes. Thus, the mesh density in the area of the main conduit 20 is lower than in the base knit, which can be preferably achieved by selecting an appropriate knit pattern. The second weave pattern also typically has a relatively small weight per unit area and breathability, and also has a different extensibility depending on the second weave pattern selected. The weave pattern of main conduit 20 is referred to as a knitted mesh.

The first knitting pattern 12 of the basic knitted fabric is provided at the same position on the path of the lower leg region U as the second knitting pattern of the main line 20. The second weave pattern of the main conduit 20 may also be woven with thinner yarns than the yarns of the base knit, which may result in a lower density than the first weave pattern.

In the main line 20, i.e. in the region of the second weave pattern, the penetration of the sweat evaporating from the foot surface is increased by climate control of the stocking 1. Knitwear having areas of different functionality can be produced by knitting techniques. By appropriate setting or programming of the knitting machine, the different zones can be automatically formed in one knitting process.

Experiments have shown that the main line 20, when extending through the tubular lower leg region U, should taper in its course starting from the sole region 11 in the direction of the junction region 10. Thereby improving the climate adjusting effect. The main conduit 20 tapers along the calf region U of the climate adjusting stocking 1 at least from an initial diameter D to a terminal diameter D at the terminal end of the main conduit 20. The initial diameter D and the end diameter D follow the circumference of the climate-adjusting stocking 1 and form straight portions of the main conduit 20 between the outer edges at different heights. As shown here, the main conduit 20 may end in the front of the junction region 10. The taper of the main conduit 20 extends to the end of the main conduit 20, which has an end diameter d. Thus, the diameter of the main conduit 20 continuously decreases from the initial diameter D to the smaller end diameter D.

The initial diameter D is measured at the sole end height F before the calf region U is formed by the long tube of stocking. When the stocking 1 is worn, the end of the sole and the starting point of the long tube or calf region U are located approximately at the level of the ankle bones of the wearer. The main conduit 20 is continuously tapered, i.e. continuously braided.

It is known that the bernoulli effect occurs in the main conduit 20 due to the tapering, which can also be estimated by the known bernoulli theorem. The flow rate of the hot and humid air increases gradually from the initial diameter D to the terminal diameter D due to the different diameters or gradual decrease in diameter. The preferred D/D ratio should be 1.5 or more. Since the thickness of the knitted net forming the main conduit 20 remains the same along the direction of the main conduit 20, the cross-sectional area varies due to the variation in diameter.

Due to the increased flow rate of the hot humid air, the hot air, including moisture, can be better conducted out through the tapering main duct 20 than the climate adjusting duct known in the prior art. In the climate control tubes known from the prior art, it is not yet known what effect is achieved by a suitably shaped cross section of the climate control tube 2. As can be seen from fig. 1 according to the prior art, the diameter of the climate control duct is even greater in the direction of the joining region and at the upper height of the sole or foot joint.

Due to the tapering of the main conduit 20, which is preferably made of knitted mesh, the speed of the removal of moist and overheated air is even faster in each foot movement when wearing the stocking 1 compared to a tight shoe. Thus, the stocking 1 can conduct out hot and humid air and provide cool, dry air to the foot, so that the foot can better "breathe" in the shoe.

The main conduit 20 is preferably arranged on the medial and lateral sides of the stocking. Particularly preferred is a connecting line made of knitted mesh, not shown here, which connects the main line 20 continuously inside and outside the lower part of the sole region in the sole region 11. The main line 20 along the inner side of the stocking 1 and the main line 20' along the outer side are also connected together under the sole S by connecting lines. Typically, there is only one continuous main channel 20 which tapers from the medial and lateral plantar regions in the distal direction of the calf region U. The tapering is located approximately at the initial diameter D of the foot joint height and extends along the calf region U in the direction of the coupling area 10 to the terminal diameter D.

In an advantageous embodiment, a plurality of branch lines 21 branching off from the main line 20 are braided. The branch line 21 is arranged in the calf region U. The branch line 21 furthermore has a knitted mesh pattern which is more breathable than the basic knitted fabric. The weave pattern or yarns of the main conduit 20 and the branch conduit 21 may be the same for simplicity reasons. Typically, the branch line 21 is oriented at a branch angle α of less than 90 ° to the longitudinal axis of the main line 20. Accordingly, the branch line 21 is disposed in the direction of the junction region 10 and away from the main line 20. The tapering of the main line 20 leads out the hot and humid air at a higher speed, and in addition, the branch line 21 can additionally lead out the hot and humid air, thereby improving the climate-conditioning effect.

Further, a branch line 22 is woven over one or more of the branch lines. The branching line 22 also has at least one branching line 21 along the lower leg region U. The bifurcated line 22 also has a knitted mesh or knit which is more breathable than the base knit or first knit pattern 12. The bifurcation line 22 is preferably arranged in the calf region U in the upper part of half the sock height h/2 and particularly preferably at calf level.

By means of the bifurcation duct 22, the area of the climate-adjusting stocking 1 above half the stocking height h/2 is ventilated better and a climate-adjusting effect is achieved.

In order to optimize the exhaust effect of the main conduit 20 and/or the branch conduit 21 and/or the branch conduit 22, the conduit edge projections 200 may be provided for the side edges of the conduit in all embodiments. This type of tube edge bead 200 can also be produced in a braiding process, wherein knitted fabrics with a thicker yarn thickness and/or thicker yarns than the interior of the tubes 20, 21, 22 are used in the region of the tube edge bead 200.

The climate-adjusting stocking 1 described here can be easily provided with a cushion, in particular a calf cushion, a tibia cushion, a foot pad, a toe cushion, a thenar cushion, a heel cushion or an achilles cushion. Wherein the corresponding inlay pattern must be woven into the desired position of the cushion during the weaving process.

Those skilled in the art are familiar with the production process of an inlay fabric and can program it on the same knitting machine. Inlay or cushion is provided on the other knitted layer, the basic knitted fabric or the knitted pattern with the first knitted pattern 12 and the lines 20, 21, 22. Since moisture can be better conducted away by the tapering main line 20 and the branch and bifurcation lines 21, 22, the cushion can at least partially cover the branch and bifurcation lines 21, 22.

In fig. 5, the calf region cushion 3 is illustrated as an example cushion. The calf region cushion 3 is located in the knitted layer above part of the branch lines 21 and 22, but still ensures a sufficient climate conditioning effect.

Of course, a pad may be provided in the knitted layer at the upper portion of the main pipe 20 so as to maintain the effect of the main pipe 20.

The cushion is typically made of a yarn that is different from the yarn used in the base knit region or tube. These bolsters are used in various foot areas for mechanical protection, mechanical cushioning, heat dissipation or thermal insulation.

Due to the tapering of the main conduit 20, the heated humid air can be led out at a suitable speed, so that the branch and bifurcation conduits 21, 22 achieve a sufficient effect under the cushion.

In the sectional view of fig. 6, an overlapping first knitted layer is shown, in which the basic knitted fabric and the branch lines 21 are provided, and in addition a second knitted layer provided with a cushion is shown.

The knitted fabric is formed during the knitting process and is connected together by a mesh structure. The padded second knitted layer is arranged on the outside of the climate adjusting stocking 1 and is remote from the foot of the wearer when the stocking 1 is worn. The heated humid air may be led out through a branch duct 21 below the cushion.

In another embodiment of fig. 7, a pipeline cushion 23 is provided that intersects the main pipeline 20 at least partially in the longitudinal direction. Wherein the width of the conduit cushion 23 is designed to be smaller than the width of the tapered main conduit 20. In this embodiment, the conduit pad 23 extends from the plantar region 11 or from the connecting conduit to the opposite tapered end of the main conduit 20, with a distal diameter d. In the embodiment of fig. 8, the line cushion 23 spans only a portion of the main line 20. Preferably, at least one pipeline cushion 23 is inseparably disposed at the center of gravity position of the main pipeline 20. In addition to the linear-shaped pipeline cushion 23, the pipeline cushion 23 may have a wavy or curved pattern and be positioned along the area between the sole area 11 and the joining end of the main pipeline 20. The line cushion 23 is woven with additional yarn when knitting the climate control stocking 1. The pipeline cushion 23 preferably protrudes from the knitted layer of the main pipeline 20. The material of the shoe is prevented from squeezing the main conduit 20 excessively by the conduit padding 23 when wearing the climate adjusting stocking 1. In this way, more air can be better guided out of the shoe. The line cushion 23 may also be provided in all the above-described versions of the climate control stocking 1.

One useful yarn component is a blend of polyamide, polyester, polypropylene and elastane. The mixture may also be mixed with merino wool, silk and/or metallized polyamide.

In addition to the climate-regulating hollow strands with closed air cells, various active filaments are used which fill the inner space and which prevent bacterial growth and thus perspiration.

By means of this composite yarn, a hygroscopic and moisture-repellent knitted network is formed, which is arranged in the line area. The skin is not completely covered in the area of the line, so that drips of sweat may form on the skin of the foot, which then drip into the mesh and are conducted away therefrom. Thereby improving the conduction evaporative cooling or cooling effect.
