Description

Orthopädische Schuheinlagen bzw. orthopädisches Schuhwerk Die Erfindung betriff t die Verwendung eines aus Kautschukmilch und Korkmehl bzw. Korkschrot durch Kneten und anschließendes Trocknen unter nachfolgender Pressung bei Temperaturen von 8o bis 140' unter einem Mindestdruck von 2o Atü erhaltenen Formkörpers als Füllmasse fürorthopädieche Schuheinlagen bzw. orthopädisches Schuhwerk.Orthopedic shoe insoles or orthopedic footwear The invention Affects the use of rubber milk and cork powder or cork grist Kneading and subsequent drying with subsequent pressing at temperatures from 8o to 140 'under a minimum pressure of 2o Atü obtained molding as a filler for orthopedic shoe insoles and orthopedic footwear.

Zur Herstellung von orthopädischen Schuheinlagen bzw. orthopädischem Schuhwerk sind bereits Füllmassen bekannt, die aus Korkmehl und Latex bestehen. Diese Füllinassen werden entweder aufmodelliert. oder in Formen gepreßt.For the production of orthopedic shoe insoles or orthopedic Footwear are already known filling compounds made of cork flour and latex. These filling cups are either modeled on. or pressed into molds.

Es ist weiterhin bekannt, ein Gemisch von Kautschukmilch und Korkschrot unmittelbar ohne Vortrocknung zu verpressen, womit wohl brauchbare Schuhsohlen erhalten werden können, nicht dagegen orthopädische Einlagen, die eine bestimmte Form an verschiedenen Stellen der Einlage behalten müssen und trotzdem eine gewisse Weic.hheit aufweisen müssen. Es wurde nun gefunden, daß Forrnkörper aus Preßmassen aus Kautschukmilch und Korkmehl bzw. Korkschrot, die durch Kneten und anschließendes Trocknen unter nachfolgender Pressung bei Temperaturen von 8o bis 140' unter einem Mindestdruck von 2o Atü erhalten werden, sich besonders gut als Füllmassen für Schuheünlagen bzw. orthopädisches Schuhmverk .eignen.It is also known to use a mixture of rubber milk and crushed cork to be pressed immediately without pre-drying, which probably gives usable shoe soles However, orthopedic insoles that adhere to a certain shape cannot be used have to keep different parts of the insert and still have a certain softness must have. It has now been found that molded bodies made from molding compounds made from rubber milk and cork powder or crushed cork, which is kneaded and then dried under subsequent pressing at temperatures of 8o to 140 'under a minimum pressure can be obtained from 2o Atü, are particularly good as filling compounds for footwear or orthopedic shoe sales.

Es wurde weiter festgestellt, daß die Elastizität und Dauerhaftigkeit der unter Benutzung der Füllmasse hergestellten Formkörper davon abhängt, unter welchem Druck die Füllmasse geformt worden ist. Unter Ausnutzung dieser Erkenntnis geht man bei ,der erfindungsgemäßen Verwendung solcher Formkörper zum Herstellen orthopädischer Schuheinlaggen bzw. orthopädischen Schuhwerkes so vor, daß man das als Füllmaterial dienende Gemisch von Latex und Korkniehl durchknetet, trocknet und schließlich bei erhöhter Temperatur die trockne Masse unter solchem Druck verpreßt, daß die Plastizität des Materials bei gewöhnlicher Temperatur praktisch vernichtet ist. Hierbei wird zweckmäßig der Füllmasse schon die endgültige Form erteilt. Die so erhaltene Füllmasse wird aus Kautschukmilch und Korkmehl bzw. Korkschrot durch Kneten und anschließendes Trocknen unter nachfolgender.Pressung auf Temperaturen von 8o bis ioo' unter einem Mindestdruck von :2o Atm. gebracht.It was further found that the elasticity and durability the molded body produced using the filling compound depends on it, below what pressure the filling compound was formed. Taking advantage of this knowledge one goes to, the use according to the invention of such moldings for the production orthopedic shoe inserts or orthopedic footwear so that you can Mixture of latex and Korkniehl serving as a filling material is kneaded, dries and finally the dry mass at a higher temperature such Pressure pressed that the plasticity of the material at ordinary temperature is practical is destroyed. In this case, the filling compound is expediently given its final shape granted. The filling compound obtained in this way is made from rubber milk and cork powder or crushed cork by kneading and subsequent drying with subsequent pressing to temperatures from 8o to 100 'under a minimum pressure of: 2o atm. brought.

Die Füllmasse wird auf zdie entsprechende Einlage aufgeklebt und fertig zugerichtet. Eine derartige Einlage behält dauernd ihre Form, ohne daß ihre Weichheit beeinträchtigt ist. Sie bricht nicht durch und ist in hohem Maße elastisch.The filling compound is glued to the corresponding insert and that's it mangled. Such an insert permanently retains its shape without losing its softness is impaired. It does not break through and is highly elastic.

Als Korkschrot verwendet man vorzugsweise ein «XIaterial, das etwas Rinde, jedoch keinen Staub enthält. Die verwendete Kaut-#;chu,l#:milch (Latex) weist einen Trockengehalt von 55 bis 75 % auf und wird vorteilhaft in solcher Menge zugesetzt, daß auf 4oo Korkschrot 5oo bis 6oo g Latex kommt.The crushed cork is preferably a material that contains some bark but no dust. The chewing - #; chu, l #: milk (latex) used has a dry content of 55 to 75% and is advantageously added in such an amount that there are 500 to 600 g of latex for every 400 cork grist.
