Abstract

1.

Description

Die Erfindung betrifft ein Schuhwerk gemäß Oberbegriff des Anspruchs 1 oder 2.The invention relates to footwear according to the preamble of claim 1 or 2.

Wasserdampfdurchlässiges (schweißdurchlässiges) Schuhwerk ist grundsätzlich bekannt. Als wasserdampfdurchlässiges (schweißdurchlässiges) Schuhwerk wird solches bezeichnet, welches den Fußschweiß im Material (z. B. Leder) zwischenlagert und dann nach außen abführt. Gegenüber dem Eindringen von Feuchtigkeit von außen, z. B. Regenwasser, bieten diese Schuhe einen nur relativen Schutz. Im Regen oder bei nasser Straße läßt das bisher bekannte wasserdampfdurchlässige (schweißdurchlässige) Schuhwerk nach einiger Zeit Wasser von außen nach innen eindringen. Dadurch ergibt sich ein unangenehmes Innenklima im Schuhwerk, und die Krankheitsgefahr (z. B. Erkältung) steigt an.Water vapor-permeable (sweat-permeable) footwear is generally known. Water vapor permeable (sweat permeable) footwear is one that temporarily stores foot sweat in the material (e.g. leather) and then removes it to the outside. Compared to the ingress of moisture from outside, e.g. B. rainwater, these shoes offer only relative protection. In the rain or on wet roads, the previously known water vapor-permeable (sweat-permeable) footwear allows water to penetrate from outside to inside after some time. This creates an unpleasant indoor climate in the footwear and the risk of illness (e.g. cold) increases.

Um dies zu vermeiden, trägt man für die nasse Jahreszeit Schuhwerk, das wasserdicht ist oder zumindest eine wasserdichte Sohle hat (z. B. Krepp, Kunststoff oder Gummi). Damit werden zwar die Nachteile des Wassereindringens in das Schuhwerk vermieden, auf der anderen Seite entstehen jedoch neue Probleme. Da die Wasserdampfdurchlässigkeit (Schweißdurchlässigkeit) fehlt, kann dieses Schuhwerk meist den Fußschweiß weder zwischenlagern noch ihn nach außen abführen. Es kommt zu einem Innenschuhklima mit erhöhter Feuchtigkeit und erhöhter Temperatur. Dies schafft Unbehagen und ist der ideale Nährboden für die Entstehung und Ausbreitung des Fußpilzes.To avoid this, footwear that is waterproof or at least has a waterproof sole (e.g. crepe, plastic or rubber) is worn for the wet season. This avoids the disadvantages of water penetration into the footwear, but on the other hand new problems arise. Since the water vapor permeability (perspiration permeability) is missing, this footwear can usually neither store the sweat from the feet nor lead it away to the outside. The result is an inner shoe climate with increased moisture and temperature. This creates discomfort and is the ideal breeding ground for the development and spread of athlete's foot.

Aus der DE-A-2 737 756 ist ein Schuh bekannt, dessen Schaft aus einem Laminat mit einer wasserdichten und wasserdampfdurchlässigen Funktionsschicht aus mikroporösem Material aus Tetrafluorethylenpolymeren, insbesondere Polytetrafluorethylen besteht. Die Verarbeitungs-und Gestaltungsmöglichkeiten des Schaftes sind bei diesem bekannten Laminat sehr beschränkt.A shoe is known from DE-A-2 737 756, the upper of which consists of a laminate with a waterproof and water vapor-permeable functional layer made of microporous material made of tetrafluoroethylene polymers, in particular polytetrafluoroethylene. The processing and design options of the shaft are very limited in this known laminate.

Aus der FR-A-2 116 790 ist ein Schuh aus wasserdichtem Material mit Belüftungsöffnungen bekannt, welche auf der Innenseite des Schuhs durch ein dünnes Blatt abgedeckt sind. Das dünne Blatt besteht aus einer ersten Schicht, z. B. einem Gewebe mit Luftdurchlässen geringen Querschnitts und einer zweiten Schicht aus Polytetrafluorethylen. Eine Wasserdampfdurchlässigkeit ist bei diesem bekannten Schuh nicht gegeben.From FR-A-2 116 790 a shoe made of waterproof material with ventilation openings is known, which are covered on the inside of the shoe by a thin sheet. The thin sheet consists of a first layer, e.g. B. a fabric with air passages of small cross-section and a second layer of polytetrafluoroethylene. This known shoe does not have water vapor permeability.

Die Aufgabe der vorliegenden Erfindung besteht darin, die Unzulänglichkeiten der bekannten Schuhe zu vermeiden und ein Schuhwerk zu schaffen, das wasserdampfdurchlässig (schweißdurchlässig) ist, zugleich jedoch ein Wassereindringen von außen verhindert.The object of the present invention is to avoid the shortcomings of the known shoes and to create footwear which is permeable to water vapor (permeable to sweat) but at the same time prevents water penetration from the outside.

Diese Aufgabe wird erfindungsgemäß durch ein Schuhwerk gemäß Anspruch 1 oder 2 gelöst. Eine Funktionsschicht, die wasserdampfdurchlässig (schweißdurchlässig) ist und zugleich das Wasser von außen abhält, ermöglicht ein Diffundieren der Transpiration (Fußschweiß) und hält den Fuß trocken.This object is achieved according to the invention by footwear according to claim 1 or 2. A functional layer that is permeable to water vapor (permeable to sweat) and at the same time keeps the water from the outside, allows perspiration to diffuse (foot sweat) and keeps the foot dry.

Damit wird die Gefahr der Erkrankung (z. B. Erkältung) des Trägers reduziert und der Komfort im Schuhwerk erhöht. In vielen Fällen ist es damit möglich, mit einem Paar Schuhe auszukommen (z. B. auf Reisen, wo sonst zumindest zwei Paar nötig wären).This reduces the risk of illness (e.g. cold) of the wearer and increases comfort in footwear. In many cases it is possible to get by with one pair of shoes (e.g. when traveling, where otherwise at least two pairs would be necessary).

Diese Funktionsschicht kann aus mikroporösem Material aus Tetrafluorethylenpolymeren, insbesondere Tetrafluorethylenen, wie sie z. B. aus der DE-PS-2 123 316 bekannt sind, bestehen. Sie hat die Eigenschaft, daß sie in einer Richtung wasserdampfdurchlässig (schweißdurchlässig) ist, in der anderen Richtung jedoch eine volle Wassersperre bildet.This functional layer can be made of microporous material made of tetrafluoroethylene polymers, in particular tetrafluoroethylene, such as those found in B. are known from DE-PS-2 123 316 exist. It has the property that it is permeable to water vapor (perspiration) in one direction, but forms a full water barrier in the other direction.

Weitere Vorteile, Merkmale und Anwendungsmöglichkeiten der vorliegenden Erfindung ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen.Further advantages, features and possible uses of the present invention result from the following description of exemplary embodiments.

1. Schuhsohle1. Shoe sole

Die Schuhsohle kann aus einem oder mehreren der nachgenannten Materialien bestehen:

  • a) Alle Lederarten
  • b) Gewachsene Felle
  • c) Filze
  • d) Schäume (geschäumte Kunststoffe)
  • e) Korkulierte Kunstleder

in Verbindung mit einer Funktionsschicht.in connection with a functional layer.

Diese Funktionsschicht aus mikroporösem Polytetrafluorethylen oder aus mikroporöser Schicht(en) aus anderen Materialien mit den Eigenschaften wasserdicht/wasserdampfdurchlässig (schweißdurchlässig) wird auf, in oder unter der Schuhsohle angebracht. Die Funktionsschicht kann somit folgender Bestandteil der Sohlenkonstruktion oder auch zwischen den einzelnen Sohlen angeordnet sein:

  • a) Einlegesohle oder Fußbetteinlage
  • b) Brandsohle
  • c) Zwischensohle
  • d) Laufsohle
This functional layer made of microporous polytetrafluoroethylene or of microporous layer (s) made of other materials with the properties waterproof / water vapor permeable (perspiration permeable) is applied on, in or under the shoe sole. The functional layer can thus be arranged as part of the sole construction or between the individual soles:
  • a) Insole or footbed insert
  • b) insole
  • c) midsole
  • d) outsole

Die Verbindung zwischen den verschiedenartigen Materialien kann durch

  • a) vollflächige Verklebung,
  • b) punktförmige oder andere luft- und feuchtigkeitsdurchlässige Verklebungen,
  • c) Aufnähen,
  • d) Beschichten
    erfolgen.
The connection between the different materials can be made through
  • a) full-surface gluing,
  • b) punctiform or other air and moisture permeable bonds,
  • c) sew on,
  • d) coating
    respectively.

In all diesen Fällen hat die Schuhsohle die Eigenschaft, daß sie ein Eindringen von Nässe von außen durch die Sohlenkonstruktion in das Schuhwerk bis zum Fuß des Trägers verhindert und zugleich die vom Fuß abgegebene Transpiration (Fußschweiß) diffundiert, d. h. durch die einzubringende Funktionsschicht aus mikroporösem Polytetrafluoräthylen oder mikroporöser Schicht(en) aus anderen Materialien vom Fuß des Trägers weg nach außen zuläßt, also wasserdampfdurchlässig (schweißdurchlässig) ist.In all these cases, the sole of the shoe has the property that it prevents penetration of moisture from the outside through the sole construction into the footwear up to the foot of the wearer and at the same time diffuses the perspiration emitted by the foot (foot sweat), that is to say from the functional layer to be introduced microporous polytetrafluoroethylene or microporous layer (s) made of other materials from the foot of the wearer to the outside, so it is permeable to water vapor (sweat permeable).

2. Blattfutter2. Leaf food

Das Blattfutter kann aus einem oder mehreren der folgenden Materialien bestehen:

  • a) Alle Oberleder
  • b) Alle textilen Obermaterialien
  • c) Alle synthetischen Obermaterialien
  • d) Alle Futterleder
  • e) Alle textilen Futtermaterialien
  • f) Alle synthetischen Futtermaterialien
  • g) Alle gewachsenen Felle als Obermaterial h Alle gewachsenen Felle als Futtermaterial in Verbindung mit einer Funktionsschicht.
The leaf feed can consist of one or more of the following materials:
  • a) All upper leather
  • b) All textile upper materials
  • c) All synthetic face materials
  • d) All lining leather
  • e) All textile lining materials
  • f) All synthetic lining materials
  • g) All grown skins as upper material h All grown skins as lining material in connection with a functional layer.

Auf, in oder unter dem Blattfutter ist eine Funktionsschicht aus mikroporösem Polytetrafluoräthylen oder aus mikroporöser Schicht(en) aus anderen Materialien mit den Eigenschaften wasserdicht/wasserdampfdurchlässig (schweißdurchlässig) angebracht.A functional layer made of microporous polytetrafluoroethylene or of microporous layer (s) made of other materials with the properties waterproof / water vapor permeable (perspiration permeable) is attached to, in or under the leaf lining.

Diese Verbindung kann durch

  • a) punktförmige oder andere luft- und feuchtigkeitsdurchlässige Verklebungen,
  • b) Aufnähen,
    erfolgen.
This connection can be made through
  • a) punctiform or other air and moisture permeable bonds,
  • b) sew on,
    respectively.

Hierdurch wird das Eindringen von Nässe von außen durch wasserdampfdurchlässige (schweißdurchlässige), nicht wasserdichte Obermaterialien bis zum Fuß des Trägers verhindert, wobei die Schweißaufnahme- und Schweißabgabefähigkeit des Ober- und Futtermaterials im Schaftbereich (Blatt) voll erhalten bleibt.This prevents the ingress of moisture from the outside through water-vapor-permeable (sweat-permeable), non-waterproof outer materials to the foot of the wearer, while the sweat absorption and sweat-dispensing ability of the upper and lining material in the shaft area (sheet) is fully retained.

Das Blattfutter ist fest mit dem Schuh verbunden oder wird lose auswechselbar gestaltet.The leaf lining is firmly attached to the shoe or is designed to be loosely replaceable.

Auch ist es möglich, den gesamten Oberschuh gemäß den letztnannten Ausführungsbeispielen zu erstellen.It is also possible to create the entire upper shoe in accordance with the last-mentioned exemplary embodiments.

Wird das gesamte Schuhwerk (Schuhsohle, Oberschuh und Blattfutter) gemäß vorgenannten Ausführungsbeispielen erstellt, so liegt ein Schuh vor, der voll wasserdampfdurchlässig (schweißdurchlässig) ist, ohne daß Nässe von außen durch den Schuh an den Fuß des Trägers gelangen kann. Der Fuß bleibt in einem trockenen Klima.If the entire footwear (shoe sole, upper shoe and leaf lining) is created according to the above-mentioned exemplary embodiments, then a shoe is present which is fully permeable to water vapor (permeable to sweat) without moisture from the outside reaching the foot of the wearer through the shoe. The foot remains in a dry climate.

Dies gilt auch dann, wenn das Schuhwerk oder Teile von selbigem aus - jeweils von außen betrachtet - einer wasserdichten, nicht wasserdampfdurchlässigen (schweißdurchlässigen) Schicht und einer Funktionsschicht aus mikroporösem Polytetrafluoräthylen oder aus einer oder mehreren mikroporösen Schichten aus anderen Materialien mit den Eigenschaften wasserdicht/wasserdampfdurchlässig (schweißdurchlässig) besteht.This also applies if the footwear or parts of the same - viewed from the outside - of a waterproof, non-water vapor-permeable (sweat-permeable) layer and a functional layer made of microporous polytetrafluoroethylene or one or more microporous layers made of other materials with the properties waterproof / water vapor permeable (permeable to sweat).

Die Transpiration des Fußes (Fußschweiß) diffundiert vom Fuß weg durch die Funktionsschicht und kondensiert auf der dem Fuß abgewandten Seite der Funktionsschicht. Der Fuß bleibt somit auch in diesem Fall in einem trockenen Klima. Kondensierte Transpiration (Fußschweiß) kann durch die wasserdichte Funktionsschicht nicht mehr zurück an den Fuß gelangen.The perspiration of the foot (foot sweat) diffuses away from the foot through the functional layer and condenses on the side of the functional layer facing away from the foot. In this case, the foot remains in a dry climate. Condensed perspiration (foot sweat) can no longer get back to the foot due to the waterproof functional layer.

Es ist auch möglich, die Funktionsschicht nicht fest mit dem Schuhwerk zu verbinden, sondern auswechselbar als Einlegesohle oder Einlegschuh in das Schuhwerk einzubringen.It is also possible not to firmly connect the functional layer to the footwear, but rather to insert it interchangeably into the footwear as an insole or insert shoe.

Ergänzend zu den vorgenannten Ausführungsbeispielen werden nachstehend weitere Vorteile, Merkmale und Anwendungsmöglichkeiten der vorliegenden Erfindung anhand der Beschreibung von Ausführungsbeispielen in Verbindung mit den Zeichnungen dargestellt. Darin zeigen:

  • Fig. 5 shows a schematic cross section through footwear

In Fig. 1 ist ein Schuhwerk 1 dargestellt. Ein Blattfütter besitzt eine Funktionsschicht 2, die in diesen Ausführungsformen durch eine Schraffierung schematisch dargestellt ist. Das Schuhwerk 1 besitzt ferner eine wasserdicht zur Sohlenkonstruktion hin abgedichtete Brandsohle.1 shows footwear 1. A leaf feeder has a functional layer 2, which is represented schematically by hatching in these embodiments. The footwear 1 also has an insole which is sealed waterproof to the sole construction.

Es liegt somit auf der Hand, daß der besonders feuchtigkeitsempfindliche Bereich durch die Funktionsschicht 2 gegen ein Eindringen von Feuchtigkeit von außen abgedichtet wird. Die Funktionsschicht 2 kann hierbei den gesamten Vorderfuß umschließen oder sich nur oberhalb des Vorderfußes befinden, wobei die Abdichtung gegenüber den Sohlen in einer konventionellen Ausführungsform besteht.It is therefore obvious that the particularly moisture-sensitive area is sealed by the functional layer 2 against the ingress of moisture from the outside. The functional layer 2 can enclose the entire forefoot or only be located above the forefoot, the sealing against the soles being in a conventional embodiment.

In Fig. 2 ist die Funktionsschicht 2 (durch Schraffierung schematisch dargestellt) ein eingehängtes Futter, welches als Socken ausgebildet ist. Die diesbezüglichen Nähte sind wasserdicht versiegelt. Ebenso ist auch hier die Brandsohle auf der Unterseite wasserdicht versiegelt. Dieses Schuhwerk hat somit die Wasserdichtheit eines herkömmlichen Gummistiefels, verfügt jedoch über den erfindungsgemäßen Vorteil der vollen Wasserdampfdurchlässigkeit.In Fig. 2, the functional layer 2 (shown schematically by hatching) is a suspended lining which is designed as socks. The seams are sealed waterproof. The insole on the underside is also sealed watertight. This footwear thus has the waterproofness of a conventional rubber boot, but has the advantage of full water vapor permeability according to the invention.

In Fig. 3 ist eine Variation von Fig. 2 dargestellt. Während in Fig. 2 das Schuhwerk die Form eines Schaftstiefels besitzt, verfügt das Schuhwerk in Fig. 3 über eine Faltzunge 3. Die in Fig. 2 beschriebenen Vorteile bleiben erhalten, zusätzlich besteht die Möglichkeit einer Schnürung dieses Schuhwerks.FIG. 3 shows a variation of FIG. 2. While the footwear in FIG. 2 has the shape of a shaft boot, the footwear in FIG. 3 has a folding tongue 3. The advantages described in FIG. 2 are retained, and there is also the possibility of one Lacing of this footwear.

In Fig. 4 ist ein anderes Ausführungsbeispiel dargestellt. Hier besitzt ein Innenschuh, der auch als Socken entsprechend der Ausführungsform von Fig. 2 ausgebildet sein kann, die Funktionsschicht 2. Zusätzlich verfügt die Sohle ebenfalls über eine Funktionsschicht 2'.Another embodiment is shown in FIG. Here, an inner shoe, which can also be designed as a sock according to the embodiment of FIG. 2, has the functional layer 2. In addition, the sole also has a functional layer 2 '.

In Fig. 5 ist ein schematischer Querschnitt durch ein Schuhwerk dargestellt. Die in Fig. 4 bezüglich eines Innenschuhs oder Socken bereits angedeutete Funktionsschicht 2' ist hier hinsichtlich ihrer Funktion und Lege allgemein in einem Schuhwerk deutlicher zu sehen.5 shows a schematic cross section through footwear. The functional layer 2 'already indicated in FIG. 4 with regard to an inner shoe or socks can be seen more clearly here in terms of its function and placement in general in footwear.

Der vordere Teil eines Schuhwerks besteht üblicherweise aus einer Laufsohle 4, einer Zwischensohle 5 und einer Brandsohle 6. Im Schuh kann sich ferner noch eine Einlegesohle 7 befinden.The front part of a footwear usually consists of an outsole 4, a midsole 5 and an insole 6. An insole 7 can also be located in the shoe.

Die Funktionsschicht 2' befindet sich zwischen der Laufsohle 4 und der Zwischensohle 5 und/oder der Zwischensohle 5 und der Brandsohle und/oder der Brandsohle 6 und der Einlegesohle 7. In einer bevorzugten Ausführungsform befindet sich die Funktionsschicht 2' zwischen der Brandsohle 6 und der darunter liegenden Zwischensohle 5 und - sofern diese nicht vorhanden - der darunter liegenden Laufsohle 4.The functional layer 2 'is located between the outsole 4 and the midsole 5 and / or the midsole 5 and the insole and / or the insole 6 and the insole 7. In a preferred embodiment, the functional layer 2' is located between the insole 6 and the midsole 5 underneath and - if this does not exist - the outsole 4 underneath.
