Abstract

With the hard walking supports which prevail nowadays, the known hard and reinforced soles often affect the joints of the foot, of the knee, of the pelvis and of the vertebras. An overload of the walking heel surfaces, as well as of the joints and toe ends, may occur and cause pain at sensitive areas of the foot. The present invention relates to a sole (1) in which the above-mentioned drawbacks of reinforced hard soles (1) have been eliminated by means of soft and resilient materials (2). From an orthopaedical point of view, hard and soft walking surfaces of soles of the present invention contribute to sustain the foot where it requires a support and to provide a soft bed at areas where pain could otherwise occur, while simultaneously damping the hard shocks caused by walking.

Description

"Orthopädisch gestalteter Sσhuhboden mit harten und weichen Partien" "Orthopedically designed shoe floor with hard and soft parts"
Die herkömmlichen, weitverbreiteten Schuhe mit dicken und harten Böden, wie z.B. Zoccolis, Clogs,. Sandaletten etc., mit Bodenteilen aus Holz, Kork oder Kunststoffmateri¬ alien, vermitteln wohl manchmal eine gewisse gymnastische Wirkung, haben aber den grossen Nachteil, dass das Auftre¬ ten hart ist.The conventional, widespread shoes with thick and hard bottoms, such as Zoccolis, clogs ,. Sandals etc., with floor parts made of wood, cork or plastic materials, sometimes convey a certain gymnastic effect, but have the major disadvantage that the appearance is hard.
Solche Schuhe sind beliebt, weil sie eine gute Isolation gegen Nässe und Kälte bieten, besonders wenn Naturprodukte wie Holz oder Kork verwendet werden.Such shoes are popular because they provide good insulation against wet and cold, especially when natural products such as wood or cork are used.
Sehr nachteilig wirkt sich aber aus, dass bei jedem Schritt, besonders auf den heute vorherrschenden harten Gehflächen wie Hausböden, Strassen, Trottoirs etc. bei solchen Schuhen brüske Stösse auf die Puss-, Knie-, Hüft- und Wirbelgelenke übertragen werden. Das kann auf die Dauer zu frühzeitigen Gelenkschädigungen führen.However, it is very disadvantageous that with every step, especially on today's hard walking surfaces such as house floors, streets, sidewalks, etc., brusque impacts are transmitted to the puss, knee, hip and vertebral joints with such shoes. In the long run, this can lead to premature joint damage.
Es bringt auch keine Verbesserung, wenn diese Schuhböden auf der Lauffläche mit einer weicheren Schicht versehen werden. Diese kann weder genügend dick, noch genügend weich sein, da sonst die Stabilität des Schuhes leiden würde. Es ist auch bekannt, dass solche harte Böden zweiteilig kon¬ struiert werden können, wobei Vorder- und Hinterteil mit einer gelenkartigen Einlage verbunden werden. Solche Böden vermögen wohl den Gehablauf zu erleichtern, sie bringen aber keinerlei Verbesserung bezüglich des harten Auftrittes.There is also no improvement if these shoe bottoms are provided with a softer layer on the tread. This can neither be sufficiently thick nor soft enough, otherwise the stability of the shoe would suffer. It is also known that such hard floors can be constructed in two parts, the front and rear parts being connected with an articulated insert. Such floors may make walking easier, but they bring no improvement in terms of hard appearance.
Ein weiterer grosser Nachteil besteht darin, dass diese dicken, harten Schuhböden eine Ueberbelastung der Fersen¬ auftrittsfläche, sowie der Zehengrundgelenke und oft auch der Zehenkuppen bewirken. Hieraus können Schmerzen an diesen sehr druckempfindlichen Stellen des Fusses resultieren. Dies kann auch dadurch nicht verhindert werden, dass auf den fraglichen Sσhuhböden fusseitig über die ganze Fläche eine weiche Auflage angebracht wird.Another major disadvantage is that these thick, hard shoe bottoms cause an overload on the heel tread, as well as on the basic joints of the toes and often also on the tips of the toes. This can result in pain in these very pressure-sensitive areas of the foot. This cannot be prevented by applying a soft pad over the entire surface on the foot of the shoe floors in question.
Um die bezeichneten Beschwerden zu verhindern, oder um schon bestehende Schmerzen zu lindern, muss der Fuss nach ortho¬ pädischen Gesichtspunkten dort angehoben werden, wo er Halt braucht und dort weich gebettet sein, wo empfindliche Stel¬ len sind.In order to prevent the described complaints or to alleviate existing pain, the foot must be raised from an orthopedic point of view where it needs support and be softly bedded where there are sensitive areas.
Die vorliegende Erfindung betrifft einen Schuhboden, bei welchem die Nachteile harter Materialien unter Zuhilfe¬ nahme von weichen, resilienten Materialen, wie Polyurethan- Schäume, Latex-Schäume und dergleichen eliminiert werden.The present invention relates to a shoe bottom in which the disadvantages of hard materials are eliminated with the aid of soft, resilient materials, such as polyurethane foams, latex foams and the like.
Bei dem erfindungsgemässen Schuhboden werden der oder die harte (n) Teil (e) fusseitig so gestaltet, dass orthopä¬ disch plazierte Hohlräume angebracht werden, welche dann mit weichen, resilienten Materialien ausgefüllt werden. Dies kann durch Einspritzen, Eingiessen oder Einkleben ge¬ schehen. Damit wird bewirkt, dass die Auftrittsfläche der Ferse weich ist, die Fussgewölbe aber durch das harte Ma¬ terial von unten gut gestützt werden, während die empfind¬ lichen Zehengrundgelenke und die Zehenkuppen wiederum auf weichem Material aufliegen.In the shoe base according to the invention, the hard part (s) are designed on the foot side in such a way that orthopedically placed cavities are provided, which are then filled with soft, resilient materials. This can be done by injecting, pouring or gluing. This has the effect that the tread surface of the heel is soft, but the arch of the foot is well supported by the hard material from below, while the sensitive basic toe joints and the toe tips in turn rest on soft material.
Der erfindungsgemässe Schuhboden wird vorzugsweise in zwei Phasen hergestellt. Dabei kommen Materialien zur Anwendung, die im Endzustand stark unterschiedkiche Härtegrade aufwei¬ sen. In der ersten Phase werden die harten Bodenteile so gestaltet, dass fusseitig konkave Hohlräume mit den weichen, resilienten Materialien aufgefüllt, was durch Einspritzen,- giessen, kleben- vulkanisieren geschehen kann. Dabei kommen speziell hiefür hergerichtete Werkzeuge und Verfahren zur Anwendung.The shoe bottom according to the invention is preferably produced in two phases. Materials are used which have very different degrees of hardness in the final state. In the first phase, the hard floor parts are designed so that concave cavities on the foot side are filled with the soft, resilient materials, which can be done by injecting, pouring, gluing, vulcanizing. Tools and processes specially designed for this are used.
