The invention relates to a piece of sportswear with at least one controlled temperature zone having the features in the preamble to claim 1.
Such a piece of sportswear is known from EB 1 476 033 B1. It comprises web-shaped partial areas, which are thickened, and thus contact the skin and form outer air channels on their rear face, as well as areas that do not contact the skin, which form inner air channels. Sweat is absorbed on the webs contacting the skin on the inside of the piece of sportswear, and then wicked away by the webs, and can evaporate via the outer air channels. Evaporation results in local cooling. Air can flow between the webs in the inner air channels, and thereby bring about a temperature compensation. In order to be able to capture the sweat that trickles down, the webs are aligned essentially transverse to the body axis. While these proven controlled temperature zones do permit outstanding sweat absorption, they have the disadvantage that air circulation in the controlled temperature zone is only possible parallel to the webs. Warmed air cannot rise along the body axis inside of the controlled temperature zone.
Therefore, the object of the present invention is to improve a piece of sportswear with at least one controlled temperature zone of the kind mentioned at the outset in terms of air circulation, while keeping the good characteristics with respect to sweat absorption and sweat evaporation.
The present invention proposes a piece of sportswear with the features in claim 1 as the solution.
According to the present invention, the controlled temperature zones do not comprise webs and air channels that are continuously aligned parallel to each other, but rather comprise several isolated controlled temperature elements, of which each is separately designed in the known manner, but only has at least one web that does not extend over the entire width of the controlled temperature element. The controlled temperature elements are separated from each other in a transverse direction to the vertical body axis by lateral separation zones.
Within the meaning of the present invention, separation zones are the areas laterally next to a controlled temperature element or between two adjacent controlled temperature elements. The controlled temperature elements are also separated from each other vertically, specifically by transversely running or inclined inner air channels, as already the norm according to prior art. The separation zones are basically also inner air channels, but the linguistic differentiation serves to better characterize the invention with regard to the ensuing directions in which air flows upward and sweat runs off.
The controlled temperature elements are enveloped by textile fabrics. Formed between the latter are the inner channels, through which air circulates. The controlled temperature elements are arranged in such a way that drops of sweat on the skin cannot run from the top down through the entire controlled temperature zone, because they are respectively captured in a lower lying sweat collection area, the ensuing web lying on the skin. To this end, the controlled temperature elements positioned at varying heights relative to the vertical body axis are laterally offset to each other. The elements can be arranged in various ways, which all share in common that the areas contacting the skin and those not contacting the skin alternate or are offset relative to each other so as not to allow a drop of sweat to continue trickling down. At the same time, the offset controlled temperature elements only present a slight obstacle to rising air. The air on the skin surface can circulate in several directions, since air channels in the vertical are kept open by the arrangement of controlled temperature elements with interspersed separation zones. As a result, warmed air can rise through the controlled temperature zone. The chimney effect associated therewith improves moisture removal, and thus cooling of the skin.
The arrangement preferably follows a uniform pattern, but can also be non-uniform, as long as the basic principles of the invention are followed during the formation and arrangement of controlled temperature elements, specifically of providing separation zones to enable a vertical air flow on the one hand, and arranging the separation zones laterally offset on the other, so that sweat trickling down can be captured in the respective rows lying the next level down. The controlled temperature zones with the controlled temperature elements are thus optimally adjusted to the body zones that sweat especially heavily during sports activity.
The offset arrangement relates in particular to a vertical body axis. However, this does not necessarily mean that the alignment has to be exactly vertical when an athlete is wearing the piece of sportswear in the invention, but rather is intended to characterize a direction of air flow, i.e., the direction in which the warmed air can rise along the body surface of the athlete. Of course, this direction of air flow will somehow be directed against the direction of gravity in the usual movement patterns of the athlete, wherein not only a precisely vertical, but also inclined direction of air flow is possible. Several flow vanes can also be formed on the piece of sportswear or even inside of the same controlled temperature zone, meaning the air flow can be fanned out. It is only important in terms of the invention that the direction of air flow not be interrupted by the barriers lying in the flow path that are formed in prior art by the webs.
The direction in which the drops of sweat run off extends opposite the direction of air flow. According to the invention, this direction is in turn to be interrupted, so as to capture the sweat trickling down. Such a barrier created by the laterally offset arrangement of controlled temperature elements need not be present in each row of controlled temperature elements. A sequence of rows without barriers can also be detached by at least one pair of rows offset relative to each other, in which the sweat is then captured.
The controlled temperature zones can be generated by knitting, but also by adhesively bonding elements onto fabrics or other textiles.
The shape and arrangement of the controlled temperature elements can be selected in different ways, wherein all embodiments share in common that the areas contacting the skin and those not lying on the skin alternate with each other or are offset relative to each other so as to prevent a drop of sweat from trickling down unimpeded, and instead capture each drop of sweat again as quickly as possible.
In horizontal projection, the controlled temperature elements can be shaped like a Y, a V, an X, a double-Y or the like, for example, since these shapes are readily suitable for capturing a drop, while at the same time posing only a slight obstacle to laterally passing, rising air.
The controlled temperature zones on the clothing can vary in configuration in the overall extension, with the inclusion of all individual controlled temperature elements, so as to yield various additional advantages. For example, they can be vertically elongated to achieve a pronounced chimney effect, and to in this way be able to transport air from as far down as possible and transport it toward the top at the collar of a shirt or a pant waistband, where it then exits.
The textile fabric structure is preferably a knitted fabric that forms the controlled temperature zone, and is either specially designed for this purpose or connected with the base fabric of the piece of sportswear. In order to form the structures that rise in relation to the body axis and are visible on the following figures, the following measures can be provided while knitting:
The invention will be explained in greater detail below with reference to the fingers. The figures specifically show:
In the depicted exemplary embodiment, the controlled temperature zone 10.1 consists of a uniform arrangement of individual controlled temperature elements 12.1. Each controlled temperature element 12.1 in itself has at least one area in which the woven or knitted fabric is less elastic and/or shirred by shorter tension zones 15.1, thereby yielding a configuration shaped like a U or V in cross section on the inside of the piece of clothing to be facing the skin 200 of the wearer. This results in a so-called web 14.1 on the inside of the textile fabric structure 11.1. Sweat is captured at the areas of the tip of the web 14.1 contacting the skin 200, and absorbed by the textile. Inner air channels 13.1 are formed between the webs 14.1 contacting the skin 200, through which air can circulate over the skin surface.
The captured sweat is partially transported via the textile, hygroscopic lateral walls of the webs 14.1 to the top side of the controlled temperature zone 12.1 until into the surrounding areas 17.1 of the controlled temperature elements 12.1, which are kept a specific distance away from the skin surface 200 by the webs 14.1. The sweat can here evaporate especially well. The evaporative cooling in turn cools the air in the inner air channels 13.1 lying below the surrounding areas 17.1.
Channel-shaped structures arise on the rear face of the webs 14.1 and form outer air channels 18.1, through which evaporation also takes place.
Because the outer air channels 18.1 are not completely spanned by the tension zones 15.1, captured sweat can also evaporate through them without heat accumulating at the controlled temperature elements 12.1.
The controlled temperature elements 12.1 are arranged in the textile fabric structure 11.1 in such a way as to establish two essential directions, specifically a body axis X that runs essentially vertically with the wearer in an upright posture and corresponds to an air flow direction, and a direction transverse thereto, which runs perpendicularly to the body axis or at an obtuse angle thereto. In the transverse direction, the individual controlled temperature elements 12.1 are separated from each other by the surrounding areas 17.1, among which inner air channels 13.1 are formed. The webs 14.1 of adjacent controlled temperature elements 12.1 are further separated from each other by separation zones 16.1 in their extension in the transverse direction.
While the outer air channels 18.1 formed in the channels of the shirred textile are also interrupted at the separation zones 16.1, there is a transverse connection joining together the individual inner air channels 13.1 on the inside of the controlled temperature zone 10.1, underneath these separation zones 16.1. The separation zones 16.1 and inner air channels 13.1 are thus parts of an air channel network, which is formed on the inner side of the fabric structure 11.1 to be facing toward the body side of the wearer.
The resultantly achieved effects will be explained below by the respective top view of the different exemplary embodiments of controlled temperature zones 10.2, . . . , 10.6 designed according to the invention, which are depicted on
