Description

Sock.

The invention relates to a sock, in particular for use during sports activities, according to the preamble of claim 1.

Human feet often meet housed in strong shoes, especially when the person moves a lot and quickly, for example, during activities sports. Already only by strong footwear is generated on the feet a more sweat When the person develops an activity sporty, this generation of sweat is greater than normal. Market Stall that the accumulation of sweat in the shoe and / or in the sock increases the risk of blistering of the foot is sought to facilitate the evacuation of sweat from the shoe and / or the sock.

From DE 29715762 U1 a medium with climate regulation, in particular for use in leisure sports modalities, such as running, skating online, skiing or the like, which has at least one air channel integrated that reaches from the sole of the foot to the edge and It consists of a net and knit fabric with climate regulation. The climatic channel allows the evaporation of most of the moisture generated since sweat moisture is transported from  the area of the sole of the shoe to an area of the middle in which It can evaporate freely.

A patent 1275761 A1 also knows a sock in which functional zones and / or of reinforcement; the reinforcement zone is arranged in the support zone of the foot The functional zone extends in the standing portion both by the throat as by the long plantar ligament. Area functional is laterally separated from the reinforcement zone through a separation line. In the reinforcement zone and the zone Functional air channels are incorporated. In the functional zone, the air channels are arranged next to the line of separation of the reinforcement zone in an area of bands.

The objective of the present invention is to improve additionally the evacuation of moisture from the shoe. This goal it is achieved according to the invention by the characteristics of claim 1.

With the invention a sock has been created, in particular for sports activities, which further improves the evacuation of sweat from the shoe and / or the sock. When anticipating a climate channel in the support zone there is the possibility of transport moisture generated in the area of the sole straight out from the sole of the foot through of the climate channel. Moisture can then escape through of the ventilation holes present in the footwear. The connection of the climatic channel with the lateral air channels provides an additional way to evacuate the sweat from the plant area of the foot. In the case of air channels present on the inner faces and outside of the leg, the connection of the air channels causes an additional air circulation in the shoe.

In a variant of the invention, the zone of Sock support presents a central climate channel from which additional climatic channels leave towards the outer zone of the sock. In this way a uniform climate is obtained in the area of support for. In addition there is a pressure compensation between the channels, which leads to a uniform dehumidification under load. It also produces a pleasant sensation when stepping on.

Figure 10 depicting the area of sock support with an additional air channel on the faces internal and external leg.

The sock selected as an example of embodiment (fig. 1) consists of a foot portion 1 and a cane 2. The foot portion 1 has a toe zone 11, an area of heel 12 and a support area 13 located between the toe areas and heel. Zones 11, 12 and 13 may be manufactured with a reinforced material, as depicted in the example of realization. It is also possible to use combinations of materials, such as virgin wool with fiber materials elastic, for example elastane. It is also possible to arrange Fillers or additional pads in the mentioned areas.

At its opposite end to the foot portion 1, the rod 2 is equipped with an edge 21. In the calf area rod 2 is provided with fillings 22, being provided in the example depicted rod-shaped pads; They are Possible other forms of fillings. Also at the bottom of the tibia, in the transition to the instep of the foot portion, 23 fillings are arranged. It is also possible to arrange some fillings in the area of the Achilles tendon.

Fillers are usually made with synthetic or woven threads or composite yarn or materials Similar. In the exemplary embodiment, the sock fillings they are made with hollow fibers that are covered by spinning with wool or cotton. Hollow synthetic threads cushion Especially well the impact and pressure. The support zone 13 It can be made with microfiber knitwear, which helps to reduce friction. According to the needs, the staff also It can be made with microfibers in the toe areas and heel.

The sock is also equipped with a bandage on cross 24 which consists of an elastic fabric with regulation Climate The cross bandage 24 supports the ankle in the area of transition between leg and foot.

In the exemplary embodiment of the edge 21 part an air channel 25 that reaches the support zone 13 and is It consists of a net and knit fabric with climate regulation. He air channel 25 contributes to evacuate moisture from the area of support up. An air channel can also be provided 25 of this type on the inner side of the leg or on both sides of the sock.

In the support zone 13 of the sock is provided at least one climate channel 26. In the example of embodiment according to figure 2 three channels are provided Climate 26. Support zone 13 is divided by channels Climate 26. Climate channels 26 begin and end in the outer edge of the support area and is made in the form of arc, which increases the effective length of the channels. This effect is further intensified by wavy settings of the climatic channel in the embodiment according to figure 3. The increase in the effective length of the channels increases transport capacity and the refrigerated surface is enlarged by  The support zone. As shown in Figure 4, the channels 26 can cross the entire support area 13 reinforced of the sock, that is, they can also extend to the areas sides that wrap the foot. The climatic channels 26 are They consist of a net and knit fabric with climate regulation. They can be configured in such a way that the thickness of the fabric of net and point equals the thickness of the support area so result in a continuous surface. This positively influences The comfort of use.

In the exemplary embodiment according to figure 5, the climatic channels 26 in the support zone 13 of the sock are Tailored. Through partial narrowing 261 of climate channel 26 is able to accelerate the driving of air (the so-called Venturi principle). So, on the one hand it accelerates the evacuation of moisture from the support area 13 and, by another, it is possible to increase the refrigeration capacity in this area. This advantage may be greater if the climatic channels 26 have a essentially circular cross section (figure 6). In this configuration, also narrowing 261 presents a section practically circular cross section. The unclosed segment of the channel 26 is marked with "b". In the extreme case, the distance b is reduced under load a b = 0, generating a section circular cross closed. Climate channel 26 presents then the shape of a Laval nozzle, which improves additionally the positive properties.

In the exemplary embodiment according to figure 7 It is arranged in the central longitudinal axis of the support area 13 a central channel 262 from which channels on both sides depart 26 arched climatic ending at the outer edge of the area support 13. Through the central connection of the climatic channels 16 through the central channel 262 a uniform climate is obtained in the  support zone 13. The connection also generates the same pressure in all climatic channels 26, achieving dehumidification uniform under load. The uniform pressure also produces a nice feeling when stepping on. As a variation of the example of realization there is the possibility of extending the central channel 262 beyond the support zone 13, to the toe zone 11 and / or the heel area 12.

In the exemplary embodiment according to figure 8 an air channel 25 is provided on the inner side of the leg. The air channel 25 extends towards the arch of the foot. In the transition from the arch of the foot to the support area 13 of the sock split the climatic channels 26 arranged in the form of a star. In this arrangement, the climatic channels 26 reach wide areas from the support area, so that it is possible to evacuate the humidity throughout the support area. In general, the width and the Length of climatic channels 26 can be freely chosen. Also the number of climatic channels 26 is variable. Increasing of the lengths and / or widths of the climatic channels 26 or the increase in the number of climatic channels 26 allows to increase the moisture that can be transported.

In the exemplary embodiment according to figure 9 equivalently, an air channel 25 is provided in the face external leg, from which the three climatic channels depart 26. The climatic channels extend in star form until the arch of the foot.

In the exemplary embodiment according to figure 10 an air channel 25 is arranged on the inner and outer faces of the leg, respectively. The climatic channels 26 are extend in this case between the air channels present in the internal and external faces of the leg. Also in this case it they can choose the number and dimensions practically at will of the climatic channels. The connection of the channels 25 present on the inner and outer sides of the leg produces a circulation of optimal air in the shoe, so that you can evacuate a maximum amount of air humidity in the shoe and / or sock.

In addition to the embodiments There are also other possibilities represented in the figures distribution and orientation of climatic channels 26. Thus, in the exemplary embodiments according to figures 8, 9 and 10 is also it is possible that the climatic channels extend towards the zone of the toe and / or heel. When in the description and in the claims talk about socks, the invention is not limited only to these; Moreover, this term also includes means, leotards and the like, to which the invention also falls.
