Description

Sock.

The invention lies in a sock, especially For use during sports activities.

Human feet are often housed in firm footwear. This is the case especially when the person moves a lot and quickly, for example, during activities sports. Especially during movements that involve a greater rolling of the foot, such as during powerwalking, that is, when walking for a prolonged period of time at a high speed, the foot is exposed to large loads that, due to the shape of the sole of the foot curved inwards, They are especially concentrated in the area of the tenares and heel. The curvature of the sole of the foot is just the opposite of Rolling movement of the foot when walking or running. How Consequently, the metatarsal area is under tension constant because of insufficient support surface or because of lack thereof, which can lead to an increase in contractions In addition, due to the uneven distribution of the load, a greater effort of the tendons can be created and ligaments

The patent (utility model) DE20016825U describes a sock according to the preamble of claim 1.

The invention aims to remedy this problem. The invention aims to provide a sock that causes a homogeneous distribution of the charges produced during sports activities such as, for example, powerwalking, all over the surface of the sole. According to the invention, This objective is achieved because the plant has an area of Rounded tread, the tread zone being configured as a curvature and the curvature being oriented outwards.

With the invention a sock is provided specially intended for use during sports activities such as powerwalking, which causes a homogeneous distribution of the load all over the surface of the sole. When providing an area of rounded tread out, compensates for the natural curvature of the metatarsal and, therefore, a support surface is achieved keep going. In this way contractions are avoided in the area of metatarsal and premature foot fatigue is counteracted. Also I know counteracts dragging the feet when walking.

According to an embodiment of the invention, in the climatic zone of the sock is planned a climatic channel. From In this way, there is the possibility of transporting moisture that is produces in the area of the sole of the foot, through the channel climate, evacuating it directly from the area of the sole. Then, moisture can escape through holes in existing ventilation in footwear.

According to a variant of the invention, the area of tread of the sock presents a central climatic channel, from which derive other climatic channels to the outside area of the sock. In this way, a homogeneous climate is achieved in the area of tread. In addition, a pressure compensation between the channels, which leads to a homogeneous removal of moisture under load In addition, it creates a pleasant sensation when stepping on.

According to another embodiment of the invention, The climate channel is curved or wavy. In this way, it achieves an increase in the effective length of the channel, which by one part causes an increase in transport capacity and, for On the other hand, it increases the cooling surface in the area of tread.

According to another embodiment of the invention, in the tread area, the channels are configured with a reduced diameter For the partial narrowing of the path of the channel achieves accelerated air conduction which in turn causes the acceleration of moisture evacuation from the area of tread and an increase in cooling capacity in said zone.

Preferably, optionally on the side inside and / or outside of the leg part of the sock, is planned an air channel that is connected in the area With the climate channel. In this way, there is an additional way to evacuate sweat from the area of the sole. In the case of air channels on the inner and / or outer side of the leg, through the communication of the air channels a additional air circulation inside the footwear.

According to another embodiment of the invention, The sock has padded. The padding can be arranged in different points of the sock. Avoid on the one hand skin chafing and, on the other, the risk of them forming pressure points on the foot.

Advantageously, the sock is equipped with an X-Cross band. The bandage X-Cross holds the ankle in the transition zone Between the leg and the foot.

Other variants and embodiments of the invention are indicated in the other subordinate claims. A exemplary embodiment of the invention is represented in the drawings and described in detail below. They show:

The sock chosen as an embodiment (figure 1) consists of a foot part 1 and a rod 2. The part standing 1 has an area of fingers 11, a heel area 12 and a tread zone 13 located between the finger zone and the zone of heel. Zones 11, 12 and 13 may be made of a material reinforced, as depicted in the exemplary embodiment. It is also possible to use combinations of material, by example, virgin wool with elastic fiber materials, for example elastane.

The sock has a tread area 13 rounded (figures 1 and 4). The curvature 131 thus formed in the area tread 13 is oriented in the opposite direction to the curvature of the sole of the foot smoking, oriented inwards; curvature 131 It is oriented out. The curvature 131 causes an outline exterior 132 rounded. Contour 132 corresponds to the development of the rolling movement of the foot when walking and running; from the placement of the heel on the floor, the foot is rolling through the curvature 131, along contour 132, to the fingers. In the front area of the tenar, as well as in the back area of the heel, the material narrows to continue the outer contour rounded.

The curvature 131 may be made of different ways. There is the possibility of doing it through a padded. For this, different pads can be used thicknesses In this case, in the central area there are pads thicker and thinner pads are available at the ends. In number function pads of different thicknesses, you can Choose a graduation between thin and less thin than the thickness. Too threads of different thicknesses can be applied, in which case the threads thicker ones are applied in the area of maximum extension of the curvature. Also, the curvature can be done by knitting it with a greater number of threads, in which case, the number of threads increases starting from the heel approximately to the center of the area of step 13, from which it decreases again towards the fingers Other embodiments of the curvature 131.

At its opposite end to foot part 1, the cane is provided with a fist 21. In the calf area, rod 2 is provided with padding 22, being provided in the example represented bar-shaped pads, being Possible other forms of padding. Also in the lower area of the shin, in the transition to the instep of the foot part, are padded arrangements 23. The provision of padded in the area of the Achilles tendon.

Generally, the quilts are made of synthetic or woven threads or composite threads or materials Similar. In the exemplary embodiment, the sock padding they are made of wool hollow chamber fibers coated with wool or cotton. Synthetic hollow chamber threads offer a especially strong shock and pressure damping. Area Tread 13 may be made of a knitted material microfibers that helps reduce friction. Also in the areas of the toes and heel, according to the requirements, the plantar area It is made of microfibers.

In addition, the sock is equipped with a bandage X-Cross 24 made of an elastic fabric, Climate regulator X-Cross 24 bandage holds the ankle in the transition zone between the leg and the foot.

In the exemplary embodiment, fist 21 part an air channel 25 extending to the tread zone 13 and which is constituted by a network knitting fabric regulator of the weather. The air channel 25 contributes to evacuate moisture from the tread area up. An air channel 25 of this type can be provided also on the inner side of the leg or both sides of the sock.

In the exemplary embodiment according to figure 2 three climatic channels are arranged 26. The climatic channels 26 interrupt the tread area 13. Climate channels 26 begin and end in the outer edge of the tread area and they are made in the form of an arc, so the length increases effective channel. This effect is further increased by the wavy configuration of the climate channel in the example of embodiment according to figure 3. By an increase in length effective channel increase transport capacity and the cooling surface in the tread area. As can be seen in figure 4, the climatic channels 26 can pass through the entire tread zone 13 - reinforced - of the sock, that is, extend also to the lateral areas that surround the foot by the sides. The climatic channels 26 are formed by a fabric of network point climate regulator. They can be configured in such a way so that the thickness of the net knit fabric corresponds to the thickness of the tread area, so that a continuous surface results. In this way, comfort is positively influenced by carrying the garment.

In the exemplary embodiment according to figure 5, the sock has 13 climatic channels in the tread area 26 made with a reduction in diameter. By narrowing partial 261 of climate channel 26 achieves an acceleration of air conduction (the so-called Venturi principle). This way, on the one hand, the evacuation of moisture from the tread zone 13 and, on the other hand, an increase of the cooling capacity in said area. In addition, the advantage it can be further reinforced if climate channels 26 have a substantially circular cross section (figure 6). In this exemplary embodiment, also the narrowing 261 has a approximately circular cross section. The section not closed of channel 26 is designated by "b". Under load, in the case extreme, the distance b is reduced to b = 0, which causes a circular cross section. So, climate channel 26 has the shape of a Laval nozzle, which additionally improves the positive properties

In the exemplary embodiment according to figure 7, the tread zone 13 has a central channel 262 of which both sides are derived 26 arched climatic channels that end in the outer edge of the tread area 13. By the central union of the climatic channels 26 through the central channel 262 a homogeneous climate along the tread area 13. In addition, the union causes a uniform pressure in all climatic channels 26, by what achieves a homogeneous elimination of low humidity load. Also, the homogeneous pressure causes a pleasant sensation when stepping on As a variant of the embodiment example, there is the possibility of continuing the central channel 262, beyond the zone tread 13, to the toe area 11 and / or the heel area 12.

In the exemplary embodiment according to Figure 8, in the tread zone 13 three air channels are provided that they flow into an air channel 25 on the inner side of the leg, that extends through the cavity of the foot. The climatic channels 26 They are arranged in the form of rays. Through this provision, the 26 air channels reach a large part of the tread area, which allows the evacuation of moisture from the entire area of tread. The width and length of the climatic channels 26, Generally, they can be chosen freely. It is also variable the number of climatic channels 26. By increasing the lengths or widths of climatic channels 26 or a increase in the number of climatic channels 26, it is possible to increase Moisture transport capacity.

In the exemplary embodiment according to figure 9, equivalent to figure 8, in the tread zone 13 are arranged climatic channels 26 leading to an air channel 25 arranged on the outer side of the leg. The channels climatic 26 extend in the form of rays to the cavity of the foot.

In the exemplary embodiment according to figure 10, an air channel 25 is disposed respectively on the side Inner and outer side of the leg of the sock. The area of step 13 of the sock features 26 climatic channels arranged between the air channels 25 in the foot cavity. Thus, also in this case they can be chosen substantially freely both the number and the dimensions of the climatic channels. With the junction of the air channels 25 on the inner side and the side outside of the leg an optimal air circulation is achieved inside the footwear, which allows to evacuate a maximum of moisture from the footwear or sock.

In addition to the embodiments represented in the figures, there are also other possibilities of  distribute and guide climate channels 26 in the tread area 13. Although the description and claims speak of socks, the invention is not limited only to these; rather this concept also covers socks, socks and similar, to that the invention relates in the same way.
