Description

Description [0001] The invention concerns an article of clothing in particular for being worn directly on the skin, from a water-tight and/or wind-tight woven fabric, composed of a climatic membrane and of a carrier material, wherein the carrier material faces the skin.

[0002] Clothing essentially has the task of protecting the body against external influences. The external influences consist in the first place of weather factors, i.e., the action of wind, moisture, and cold on the body. Furthermore, clothing has the task of giving the user a comfortable feeling of wear. Especially in the case of sports activities or also during high outdoor temperatures, a good thermal transport of the energy produced by the body as well as the sweat produced by the body is important.

[0003] In order to accomplish good protection against weather factors, the use of climatic membranes is known. This make it possible to defend against wind or water acting on the body from the outside, but at the same time they provide for a vapor permeability from the inside to the outside in order to make possible a thermal transport of the energy and the sweat produced by the body. The best known membranes of this kind are those under the brand "Goretex®" or "Sympatex®".

[0004] While the use of climatic membranes basically affords the possibility of transporting heat produced by the body to the outside, this is only possible in to limited extent on account of the technical conditions of the membranes. In particular, during exceptionally physically strenuous activities such a running or bicycle riding, the known membranes have only very limited ability to transport the heat and moisture produced by the body to the outside.

[0005] GB 2388297 A discloses sport shirts with ventilation channels. The channels have openings and constitute an aeration region between the skin and the fabric (see claim 1). The channels are supposed to carry away the heat and reduce the formation of sweat (see page 2, paragraph 2).

[0006] In DE 202006012701 U1, water-tight and wind-tight garments with improved air circulation for use during sports activity are disclosed. Here as well a channel is described, which is formed between two spacing elements arranged on the side of the garment facing the body and which has a partial narrowing (see paragraph [0008]). However, neither a climatic membrane nor a transporting of sweat in the sense of the present application are disclosed.

[0007] EP 1972217 A1 discloses a covering material for articles of clothing, comprising an inner and an outer layer, by which a channel is formed. The inner layer is permeable to sweat and the outer layer is permeable to water vapor (see claim 1). Air flows through the channel, so that the body temperature and the transport of heat can be regulated (see paragraph [0001]). Furthermore, in contrast with the present application, a separation between carrier material and the channels is described (see paragraph 14 in conjunction with Figs. 2 and 4 of EP 1972217 Al).

[0008] The invention proposes to remedy this situation. The invention is based on the problem of creating an article of clothing which is able, even during exceptionally strenuous physical effort and thus very great buildup of heat and sweat, to provide an adequate transport of heat and sweat. According to the invention, this problem is solved in that the channels formed in the carrier material have a narrowing (15) of their cross section in their middle, while the channels (13) are embedded directly in the carrier material (12) and the carrier material (12) can switch between the stretched and the unstretched state in order to make possible a continual enlarging of the cross section of the channels (13) followed by a decreasing, so that a continual pumping effect can be created.

[0009] The invention creates an article of clothing, especially for direct wearing on the skin, which produces a definite transport of sweat and heat even during very great physical exertion. At the same time, the channels create a further possibility of heat and sweat transport which contributes to improving the bodily climate in addition to the possibility afforded by the membrane.

[0010] According to the invention, the carrier material is stretchable. Thanks to the stretchability of the carrier material, the possibility is created of a changing of the dimensions of the channels during the sports activities on account of the movements of the athlete. For example, stretching movements produce a stretching of the channels, which are retracted again after the stretching is over. In this way, during constant movements, a pumping effect is produced in the channels which leads to an improved transport of heat and sweat in the channels.

[0011] In one embodiment of the invention, the channels are provided with an opening at one end. This affords the possibility of removing the heat and the sweat produced by the body at a definite location from the article of clothing.

[0012] In another modification of the invention, the channels are provided with an opening at both ends. This creates the possibility of removing the heat and moisture from the article of clothing at both ends of the channels, which increases the transport performance of the channels.

[0013] According to the invention, the channels have a narrowing of their cross section at their middle. The narrowing leads to an acceleration of the air transported in the channel. The channels then work by the Venturi principle and thus enable an additional improvement of the thermal regulation.

[0014] Other modifications and embodiments of the invention are indicated in the other subordinate claims. A sample embodiment of the invention is shown in the drawing and shall be described in detail below. There are shown:

[0015] The article of clothing 1 chosen as the sample embodiment is suitable in particular for direct wearing on the skin. It consists of a water-tight and wind-tight fabric, which is made from a laminate as a climatic membrane. The climatic membrane 11 is arranged on a carrier material 12. The carrier material 12 faces the skin 2 and in the sample embodiment lies against the skin 2. For example, running trousers are chosen as the article of clothing.

[0016] Channels 13 are formed in the carrier material 12. In the sample embodiment, these run essentially horizontally. In the sample embodiments according to Figures 1 to 9, the channels 13 in top view have an approximately triangular configuration. The channels 13 in the sample embodiments according to Figures 1 to 3 and 7 to 9 are provided with an opening 14 at only one end, so that air can only emerge from the channels at this end, as symbolized by the arrows. In contrast with the sample embodiment according to Figures 1 to 3, in which the broadest cross section of the channels 13 is located at the open end, in the sample embodiment according to Figures 7 to 9 the smallest cross section of the channels 13 is provided at the open end.

[0017] In the sample embodiment according to Figures 4 to 7, the channels are provided with an opening 14 at both ends. As a result, air can emerge from the channels 13 at both ends, as is also symbolized here by the arrows. Furthermore, also in the sample embodiment according to Figs. 10 to 12, an opening 14 is provided at both ends of the respective channels 13. As a result, in this sample embodiment as well, an air outlet is possible at both ends, as is also symbolized by the arrows. In a modification from the other sample embodiments, however, a different form of channels 13 is provided in the sample embodiment according to Figs. 10 to 12. Therefore, they do not have an essentially triangular configuration, but instead the channels have a narrowing 15 roughly at their middle. Thanks to this partial narrowing, an acceleration of the transported air is produced, since the channels 13 function like a kind of Venturi nozzle.

[0018] In what follows, the functioning of the article of clothing according to the invention shall be explained with the aid of the running trousers chosen as the sample embodiment: when wearing the running trousers while running, a bending and stretching of the legs naturally occurs. When the leg is stretched out straight, the carrier material is in its normal state. Due to a bending of the knee, a stretching of the carrier material 12 occurs, so that the channels 13 increase their cross section. If after the bending the leg is stretched out once more, the carrier material 12 is retracted into its starting position, so that the cross section of the channels 13 is again retracted to its starting dimension. In this way, a continual switching between stretched and unstretched state of the carrier material 12 is produced during the running, which likewise produces a continual increasing and then decreasing of the cross section of the channels 13. As a result, a continual pumping effect is created during the running, which positively affects the transport of heat and moisture.

[0019] Thanks to the carrier material 12 lying against the skin 2, the channels 13 are surrounded on the one hand by the carrier material 12 and on the other hand by the skin 2, so that a closed wall of the channels 13 is created. In this way, a channel open only at its ends is created, enabling a very good performance in regard to the transport of heat and moisture.
