Description

Beschreibung: AufblasstiefelDescription: Inflatable boots

Der Erfindung liegt die Aufgabe zugrunde, einen Schuh zu SChaffen, der platzsparend, wärmeisolierend und wasserdicht ist.The invention is based on the object of creating a shoe, which is space-saving, heat-insulating and waterproof.

In der heutigen Zeit des Reisens wird es immer notwendiger möglichst wenig und raumsparendes Gepäck mitzunehmen. Das gilt besonders für Reisen in den Winter. Der Kofferraum oder Koffer ist dann meist schon voll, wenn man nur warme hohe Winterschuhe und ein Paar wasserdichte Gummistiefel eingepackt hat.In today's world of travel, it is becoming more and more necessary as possible Take little and space-saving luggage with you. This is especially true when traveling in the Winter. The trunk or suitcase is usually already full if you only have warm has packed high winter shoes and a pair of waterproof rubber boots.

Der Oberschuh des eingangs genannten Stiefels wird aus einem folienartigem Werkstoff doppelwandig gefertigt. Nur die Sohle 5.1 oder die Sohle und der untere Teil des Obermaterials 5.2 werden aus einem formstabialem, thermoplastischem oder elastomerem Spritzteil gefertigt.The upper shoe of the boot mentioned at the beginning is made of a film-like one Material made double-walled. Only the sole 5.1 or the sole and the lower one Part of the upper material 5.2 are made of a dimensionally stable, thermoplastic or elastomer injection molded part.

Der Raum zwischen den Folien 2 und 3 wird mit Luft durch eine oder mehrere Offnungen 1 aufgeblasen. (Einkammer- oder Mehrkammer-Typ) Durch die Luft und die eventuellen Stützfolien 4 bekommt der Schuh seine Form. Der Schuh kann mit einer oder mehreren Kammern gefertigt werden, wenn es fertigungstechnisch vorteilhaft ist. Die Nähte 6 zwischen Sohle und Obermaterial und die des Obermaterials untereinander sind zweckmäßigerweise am besten miteinander zu verschweißen. Es sind aber auch andere Verbindungsmöglichkeiten bei Verwendung nicht-thermoplastischer Werkstoffe denkbar. (kleben, vulkanisieren etc.) Der Schuh ist sehr raumsparend, wenn man zum Transport die Luft abläßt und die Folie des Obermaterials um die Sohle wickelt. Es ist also möglich ein Paar kniehohe, dicke, warme und wasserdichte Winterstiefel auf das Volumen von ein Paar Badeschuhen zusammenzupacken.The space between the foils 2 and 3 is filled with air by an or several openings 1 inflated. (Single-chamber or multi-chamber type) Through the air and the support films 4, if any, give the shoe its shape. The shoe can go with one or more chambers are manufactured if it is advantageous from a manufacturing point of view is. The seams 6 between the sole and the upper and those of the upper with each other are best welded together for practical purposes. But there are too other connection options when using non-thermoplastic materials conceivable. (glue, vulcanize, etc.) The shoe is very space-saving when you go to Transport lets the air out and wraps the foil of the upper material around the sole. So it is possible to have a pair of knee-high, thick, warm and waterproof winter boots to pack up the volume of a pair of bathing shoes.

Der Schuh ist warm, da die Luft zwischen den beiden Folien ein sehr schlechter Wärmeleiter ist. (Luft: 0,0221 W/mK - schaumartiger Kunststoff: o,1 W/mK) Vergleiche: Doppelglas bei Fenstern.The shoe is warm because the air between the two foils is very warm is a poor conductor of heat. (Air: 0.0221 W / mK - foam-like plastic: 0.1 W / mK) Compare: double glazing in windows.

Der Schuh ist sehr leicht.The shoe is very light.

Der Schuh ist wasserdicht (er muß ja auch luftdicht sein) Der Schuh hat durch die Luftkammern eine gute Fußformanpassung. Es lasen sich ferner interessante modische Effekte bei Verwendung transparenter Folien verwirklichen.The shoe is waterproof (it must also be airtight). The shoe Thanks to the air chambers, it adapts well to the shape of the foot. There were also interesting ones to read Realize fashionable effects when using transparent foils.

Eventuelle Beschädigungen lassen sich leicht reparieren.Any damage can be easily repaired.
