Description

sock

The present invention relates to a sock, especially a sock used in sports.

People's feet are often inside sturdy shoes. This is especially the case when people are exercising a lot and quickly, such as playing sports. Increased sweating on the feet thanks to sturdy shoes. People sweat more than average when they play sports. Since the accumulation of sweat in the shoe or sock increases the risk of blisters on the feet, efforts have been made to drain the sweat from the shoe or sock.

Known from DE 297 15 762 U1 is a stocking with an air-conditioning effect, especially for open-air sports, such as jogging, inline skating, skiing or similar sports, the stocking has at least one The integrated air channel, which is made of air-conditioning mesh fabric. Most of the water produced is evaporated by the conditioning channel, in which the perspiration is transported from the sole to an area of the stocking where free evaporation can take place. The known stockings with an air-conditioning effect fulfill all the tasks set for them.

The object of the present invention is to continue to improve the drainage of water from the shoe. According to the invention, this object is achieved in that at least one adjustment channel is provided in the footrest.

The invention provides a sock, in particular a sock for sports, which further improves the drainage of sweat from the shoe or sock. By providing an adjustment channel at the stepping position, the moisture generated at the sole of the foot can be directly sent out from the sole of the foot through the adjustment channel. Moisture can then escape through the vents in the shoe.

In a further development of the invention, the footrest of the sock has a central adjustment channel, from which branch off to other adjustment channels on the outside of the sock. This results in a homogeneous environment in the tread area. Furthermore, a pressure equalization is effected between the channels, which leads to uniform dehumidification under load. Furthermore, a comfortable underfoot feeling is produced.

In an embodiment of the invention, the adjustment channel is guided arcuately or undulatingly. This increases the effective channel length, which on the one hand plays a role in improving the conveying capacity, and on the other hand increases the cooling area in the tread area.

In a further refinement of the invention, the channel is designed in a waist-constricting manner at the footrest. Accelerated air guidance is achieved by locally narrowing the channel path, which in turn accelerates the drainage of moisture from the tread area and acts to increase the cooling efficiency of this area.

In a further embodiment of the invention, an air channel is optionally provided on the inside and/or outside of the leg of the sock, which is connected to the adjustment channel at the footrest. This provides an additional path for perspiration to escape from the sole of the foot. In the case of air channels on the inside of the leg and on the outside of the leg, an additional air circulation is produced in the shoe by connecting the air channels.

In a further embodiment of the invention, the sock has a cushioning pad. These cushioning pads can be placed on different positions of the sock. They reduce skin abrasion on the one hand and the formation of indentation points on the foot on the other.

Said sock is advantageously provided with an X cross strap. The X-cross strap supports the ankle bone in the transition zone between the leg and the foot.

Further refinements and constructions of the invention are given in the remaining subclaims. An exemplary embodiment of the invention is shown in the drawing and described in detail below. In the attached picture:

Figure 10 shows a sock tread area with additional air channels on the inside and outside of the leg.

The sock (see FIG. 1 ) chosen as an example consists of a foot part 1 and a sock shaft 2 . The foot part 1 has a toe region 11 , a heel region and a tread area 13 between the toe region and the heel region. As shown in the example, these areas 11, 12 and 13 are made of reinforced material. Composite materials can also be used, such as virgin wool with elastic fiber material, eg elastane. Additional cushioning or cushioning can also be arranged in the aforementioned areas.

The sock shaft 2 is provided with a sock waist 21 on its end facing away from the foot part 1 . The sock shaft 2 is provided with a cushioning pad 22 at the calf, wherein in the shown embodiment a balance bar is provided; other forms of cushioning pads are also possible. A cushioning pad 23 is also provided at the instep where the underside of the tibia transitions to the foot part. A buffer pad can also be set at the heel key.

The cushioning pads are generally made of plastic threads or composite fabrics or composite threads or similar materials. In this embodiment the sock cushion is made of hollow fibers which are woven from wool or cotton yarn. Air plastic lines are particularly impact and pressure resistant. The footrest 13 may be made of microfiber knitted fabric that helps reduce wear. The sole is made of microfiber as required in the toe and heel areas.

The sock is also provided with an X cross strap 24 made of an elastic air-conditioning fabric. The X-cross strap 24 supports the ankle bone in the transition zone between the leg and the foot.

In the present embodiment, an air channel 25 leads from the waist 21 of the sock, which leads to the foot area 13 and consists of a net fabric with air-conditioning effect. The air channels 25 help to drain moisture upward from the tread area. One such air channel 25 could also be located on the inside or both sides of the leg on the sock.

At least one adjustment channel 26 is provided in the footrest region 13 of the sock. In the exemplary embodiment according to FIG. 2 there are three adjustment channels 26 . The footrest 13 is interrupted by adjusting the channel 26 . The adjustment channels 26 begin and end at the outer edge of the footrest and are curved, thereby increasing the effective channel length. This effect is further increased by the undulating configuration of the adjustment channel according to the exemplary embodiment in FIG. 3 . The conveying capacity is improved by increasing the effective channel length and the cooling area in the tread area is increased. As shown in FIG. 4 , the adjustment channel 26 can pass through the entire sock foot step 13 , that is, it extends all the way to the side where the foot is embedded. The regulating channel 26 is made of mesh fabric with air-conditioning effect. They can be constructed in such a way that the thickness of the mesh fabric is equal to the thickness of the tread area, thus resulting in a continuous surface. This has a positive effect on the wearing comfort.

In the exemplary embodiment according to FIG. 5 , the adjustment channel 26 is formed in a waist-constricting manner in the sock foot region 13 . The acceleration of the air delivery is achieved by the local constriction 261 of the regulating channel 26 (the so-called Venturi principle). This, on the one hand, accelerates the drainage of water from the tread area 13 and, on the other hand, increases the cooling performance in this region. Furthermore, these advantages are enhanced in that the regulating channel 26 has an essentially circular cross section (see FIG. 6 ). In this configuration the constricted portion 261 has a nearly circular cross-section. The section of the channel 26 which is not closed is indicated with "b". Under load, the distance b decreases to b=0 in the extreme case, so that a closed circular cross section results. The adjusting channel 26 has the shape of a Laval nozzle, thereby additionally improving the frontal properties.

In the embodiment according to FIG. 7 , a central channel 262 is arranged on the longitudinal central axis of the footrest 13 , from which branched arc-shaped adjustment channels 26 on both sides end at the outer edges of the footrest 13 . The central connection of the adjustment channel 26 via the central channel 262 achieves a uniform environment on the tread area 13 . Furthermore, the connection leads to the same pressure in all regulating channels 26 , so that a uniform dehumidification is achieved under load. In addition, the uniform pressure also produces a comfortable wearing feeling. In a variant of this exemplary embodiment, it is possible for the central channel 262 to continue beyond the tread area 13 as far as the toe area 11 and/or the heel area 12 .

In the exemplary embodiment according to FIG. 8 an air channel 25 is provided on the inside of the leg. The air channel 25 extends to the arch of the foot. Beginning at the transition region of the sock from the arch of the foot to the footrest 13 , the adjustment channels 26 are arranged radially. Through this structure, the other parts of the stepping part pass through the adjustment passage 26, thereby being able to discharge water from the whole stepping part. In this case, the width and length of the adjustment channel 26 can generally be freely selected. The number of the adjustment channels 26 can also be varied. By enlarging the length or width of the regulating channel 26 or increasing the quantity of the regulating channel 26, the transported moisture can be increased.

In the exemplary embodiment according to FIG. 9 , an air channel 25 is equivalently provided on the outside of the leg, from which channel three adjustment channels 26 extend. The adjustment channel extends radially to the arch of the foot.

In the exemplary embodiment according to FIG. 10 , an air channel 25 is provided on the inside of the leg and on the outside of the leg of the sock. In this case, the adjustment channel 26 extends between the air channels to the inside of the leg and to the outside of the leg. Here, too, the number and size of the adjustment channels can be selected essentially freely. When connecting the air channels 25 to the inside of the leg and the outside of the leg, an optimum air circulation is created in the shoe, thus maximizing the drainage of moisture from the shoe or sock.

Besides the exemplary embodiments shown in the figures, other configurations and orientations of the adjustment channels 26 also exist. In the embodiments according to FIGS. 8 , 9 and 10 it is also possible to extend the adjustment channel at the toe and/or at the heel. The invention is therefore not limited only to the socks mentioned in the description and claims; but also includes stockings, panties and similar items, to which the invention also relates.
