Abstract

Described is a walking shoe that has a miniaturized diaphragm pump to support the ventilation of the shoe's interior space.

Description

Die vorliegende Erfindung betrifft einen Straßenschuh, der ein aktives Pumpelement zur Förderung der Innenschuh-Atmosphäre nach außen aufweist, wobei das Förderelement durch die Belastung bei jedem Schritt aktiviert wird. Entwicklungen der letzten Jahre auf dem Gebiet der Straßenschuhe haben dazu geführt, daß als Obermaterialien zunehmend geklebte Sandwich-Strukturen eingesetzt werden und der Schaftbereich des Schuhs abgepolstert wird, so daß er sich an den Fuß anschmiegt. Ferner werden aufgrund der günstigen Verarbeitungs- und Gebrauchseigenschaften als Sohlenmaterialien Polyurethan-Elastomere eingesetzt. Beide Entwicklungen haben dazu beigetragen, daß die beim Tragen des Schuh gebildete überschüssige Wärme (2 bis 3 Watt) und der Schweiß (beim Gehen ca. 6 g/h) nicht mehr vollständig durch Konvektion über den Schaftbereich (Walkarbeit) bzw. über Diffusion durch Obermaterial und Sohle abgeführt werden können. Dies führt zu einem feuchteren und wärmeren Klima am Fuß, eventuell sogar mit Kondensation, und den Folgeproblemen Blasenbildung, Hautablösung, Geruchsbildung und Hauterkrankungen. Bei erhöhter Feuchte wird außerdem der subjektive Eindruck von heißen Füßen verstärkt.The present invention relates to a street shoe that has an active pumping element to promote the liner atmosphere to the outside, wherein the conveyor element is activated by the load at every step. Developments in recent years in the field of street shoes have this led that increasingly used glued sandwich structures as upper materials be and the shaft area of the shoe is padded so that it hugs the foot. Furthermore, due to the favorable processing and Usage properties used as sole materials polyurethane elastomers. Both developments have contributed to that when wearing the shoe excess heat (2 to 3 watts) and sweat (approx. 6 g / h) no longer completely through convection over the shaft area (flexing work) or can be dissipated via diffusion through the upper and sole. This leads to a humid and warmer climate on the foot, possibly even with it Condensation, and the subsequent problems of blistering, skin peeling, odor formation and skin diseases. In the case of increased humidity, the subjective one Impression of hot feet intensified.

Die genannten nachteiligen Auswirkungen auf das Klima im Schuh haben dazu geführt, daß die aus orthopädischer Sicht und aufgrund ihrer günstigen Verschleiß-Eigenschaften wünschenswerten Ober- und Sohlenmaterialien beim Straßenschuh nur einen beschränkten Einsatz gefunden haben.The adverse effects on the climate in the shoe mentioned have to do so led that from an orthopedic point of view and because of their favorable wear properties desirable upper and sole materials for street shoes have only found limited use.

Insbesondere bei Sportschuhen mit weich-elastischem Absatz- und Sohlenmaterial wurde daher bereits vorgeschlagen, eine durch die Absatzkompression beim Laufen betätigte Pumpe zur aktiven Ventilation in den Absatz einzubauen, wobei die Pumpenbetätigung gleichzeitig der Stoßdämpfung beim Laufen dient und ferner die Innenschuh-Atmosphäre nach außen fördert, wobei Wärme und Feuchtigkeit abgeführt werden; siehe insbesondere WO 87/03789, GB 2 247 391, WO 93/07774.Especially for sports shoes with soft, elastic heel and sole material was therefore already suggested, one through the heel compression while running Installed pump for active ventilation in the paragraph, the Pump actuation also serves as shock absorption when running and also promotes the liner atmosphere to the outside, taking warmth and moisture be dissipated; see in particular WO 87/03789, GB 2 247 391, WO 93/07774.

Im Gegensatz zum Sportschuh weisen Straßenschuhe härtere Sohlen- und Absatzmaterialien mit Shore-Härten zwischen 60 und 70 auf, deren Kompression beim Gehen als Hubbewegung für eine eingebaute Pumpe unzureichend ist. In contrast to sports shoes, street shoes have harder sole and heel materials with shore hardness between 60 and 70, their compression when walking as a lifting movement for an installed pump is insufficient.

US-A-5 299 368 offenbart ein Straßenschuh mit einer in dem Absatz integrierten Membranpumpe.US-A-5 299 368 discloses a street shoe with a membrane pump integrated in the heel.

Gemäß FR 2 558 044 wurde bereits vorgeschlagen, den Absatz insgesamt als Membranpumpe zu gestalten. Dabei wird der Absatz bei Belastung gegen eine Feder zusammengedrückt und das im Absatz befindliche Luftvolumen ausgestoßen. Bei Entlastung entspannt sich die Feder, das Hohlvolumen des Absatzes vergrößert sich, so daß Luft angesaugt wird. Nachteilig bei diesem Vorschlag ist, daß sich die Fersenauflage bei jedem Schritt in der Entlastungsphase hebt, wodurch ein schlechter Lautkomfort bedingt ist. Der Vorschlag hat daher keinen Eingang in die Technik gefunden.According to FR 2 558 044 it has already been proposed to sell the total as Design diaphragm pump. The sales is against a The spring is compressed and the air volume in the heel is expelled. When the load is released, the spring relaxes, the hollow volume of the heel increases so that air is sucked in. The disadvantage of this proposal is that the heel pad lifts with every step in the relief phase, which causes poor sound comfort. The proposal therefore has none Technology found its entrance.

Die Technik beschreitet vielmehr den anderen Weg, nämlich die Optimierung der Atmungsaktivität des Obermaterials und der Speicherfähigkeit des Einlagenmaterials. Dennoch ist das Fußklima in Schuhen aus modernen, orthopädisch günstigen Materialien unzureichend geblieben.Rather, technology is taking the other path, namely the optimization of Breathability of the upper material and the storage capacity of the insert material. Nevertheless, the foot climate in shoes made from modern, orthopedic cheap materials remained inadequate.

Erfindungsgemäß wird daher vorgeschlagen, in den Absatz des Schuhs eine vergleichsweise kleine Membranpumpe einzubauen, die den Laufkomfort nicht beeinträchtigt und die aufgrund ihrer Förderkapazität in der Lage ist, die durch das Obermaterial unzureichend gewährleistete Ventilation im Sinne eines optimalen Schuhinnenklimas zu ergänzen, so daß Straßenschuhe mit den orthopädisch gewünschten Sohlen aus Polymeren, insbesondere Polyurethan-Elastomeren, und mit Obermaterialien aus geklebten Sandwich-Strukturen mit abgepolstertem Schaftbereich zur Verfügung gestellt werden können, die ein günstiges Fußklima gewährleisten, ohne daß der Laufkomfort eingeschränkt wird.According to the invention, it is therefore proposed to have a in the heel of the shoe to install a comparatively small diaphragm pump, which does not improve the running comfort impaired and which is able due to its funding capacity by the Upper material insufficiently guaranteed ventilation in the sense of an optimal To supplement indoor shoe climates so that street shoes with the orthopedically desired Soles made of polymers, especially polyurethane elastomers, and with Upper materials made of glued sandwich structures with padded shaft area can be provided that have a favorable foot climate ensure without reducing comfort.

Gegenstand der vorliegenden Erfindung ist ein Straßenschuh mit einem Absatz einer Shore-Härte von 50 bis 80 und einer in den Absatz integrierten Membranpumpe zur Unterstützung des Feuchtigkeitsaustausches zwischen Schuhinnerem und Umgebung, wobei die horizontale Querschnittsfläche des aus dem Absatz herausragenden Membranpumpenkolbens zwischen 1 und 3 % der horizontalen Absatzquerschnittsfläche beträgt und der Hub des Membrankolbens zwischen 1 und 3 mm beträgt.The present invention relates to a street shoe with a heel a Shore hardness of 50 to 80 and a membrane pump integrated in the heel to support the exchange of moisture between the inside of the shoe and environment, with the horizontal cross-sectional area of that from paragraph outstanding diaphragm pump piston between 1 and 3% of the horizontal Cross-sectional area and the stroke of the diaphragm piston between 1 and is 3 mm.

Dabei kann die Membranpumpe im Absatz so angeordnet sein, daß der Membranpumpenkolben nach unten (d.h. straßenseitig) aus dem Absatz herausragt oder aber nach oben (zur Ferse hin) aus dem Absatz herausragt. Vorzugsweise ragt der Membranpumpenkolben aus dem Absatz nach oben in den Raum zwischen Sohleninlet und Absatz heraus. Unter Belastung wird der Membranpumpenkolben in das in den Absatz integrierte Pumpengehäuse unter Verringerung des Pumpenhohlraumes derart hineingedrückt, daß er mit der Absatzoberfläche fluchtet.The diaphragm pump can be arranged in the paragraph so that the Diaphragm pump piston protrudes downwards (i.e. on the street side) from the heel or protrudes upwards (towards the heel) from the heel. Preferably protrudes the diaphragm pump piston from the heel up into the space between Sole insert and heel out. The diaphragm pump piston is under load in the pump housing integrated in the paragraph while reducing the pump cavity pressed in so that it is flush with the heel surface.

Aufgrund des geringen Hubes und der geringen Querschnittsfläche des Membranpumpenkolbens wird dieser von dem Schuhträger physiologisch nicht wahrgenommen, so daß der Laufkomfort nicht beeinträchtigt wird.Due to the small stroke and the small cross-sectional area of the diaphragm pump piston if this is not physiologically perceived by the shoe wearer, so that the running comfort is not impaired.

Vorzugsweise beträgt die horizontale Querschnittsfläche des Pumpenhohlraumes zwischen 3 und 10 % der horizontalen Absatzquerschnittsfläche, insbesondere das 2- bis 5-fache der horizontalen Querschnittsfläche des Membranpumpenkolbens.The horizontal cross-sectional area of the pump cavity is preferably between 3 and 10% of the horizontal sales cross-sectional area, especially that 2 to 5 times the horizontal cross-sectional area of the diaphragm pump piston.

Insbesondere bevorzugt soll die Förderkapazität der Membranpumpe zwischen 0,1 und 1 ml Schuhinnenatmosphäre pro Schritt betragen, entsprechend einer Förderung von 0,7 bis 3 g/h Feuchtigkeit beim Gehen.The delivery capacity of the diaphragm pump should particularly preferably be between 0.1 and 1 ml of shoe inner atmosphere per step, corresponding to one Promotion of 0.7 to 3 g / h moisture when walking.

Als Obermaterial des erfindungsgemäßen Schuhs wird vorzugsweise ein in der Schuhindustrie verfügbares Obermaterial, insbesondere in Form geklebter Sandwich-Strukturen, eingesetzt, dessen Atmungsaktivität ausreicht, um während des Gehens 4 bis 5 g/h Feuchtigkeit zu transportieren. Ein solches Obermaterial weist regelmäßig eine ausreichend hohe Atmungsaktivität auf, um die in Ruhephasen im Schuh erzeugte Feuchtigkeit aufzunehmen und nach außen zu fördern.The upper material of the shoe according to the invention is preferably an in Shoe industry available upper, especially in the form of glued Sandwich structures, used, the breathability of which is sufficient during of walking to transport 4 to 5 g / h of moisture. Such an upper regularly has a sufficiently high level of breathability in order to be able to rest during periods of rest absorb moisture generated in the shoe and convey it to the outside.

Als Sohlen- und Absatzmaterial werden Elastomere, wie Gummi oder PVC, vorzugsweise Polyurethan, eingesetzt, insbesondere Polyurethan-Schaum einer Dichte von 280 bis 800 kg/m3. Dabei werden Absatz und Sohle in an sich bekannter Weise durch Formpressen einer Polyurethan-Reaktivmischung hergestellt, wobei in die Form vor dem Befüllen mit der Reaktivmischung die Membranpumpe mit den entsprechenden Zu- und Ableitungsschläuchen für die zu fördernde Luft eingelegt werden.Elastomers, such as rubber or PVC, preferably polyurethane, are used as the sole and heel material, in particular polyurethane foam with a density of 280 to 800 kg / m 3 . The heel and sole are produced in a manner known per se by compression molding a reactive polyurethane mixture, the membrane pump with the corresponding supply and discharge hoses for the air to be conveyed being inserted into the mold before filling with the reactive mixture.
