Abstract

An inner sole (1) for a shoe, consists of a flat base sole (2) made of elastic foam material, whose shape corresponds to the shoe outline, and a number of integral raised sections (3) on the upper side made of the same material. The sole foamed material has a Shore A hardness of less than 25, especially 10-20, and has a smooth cover layer (20), so the hardness of the inner sole is in excess of 25, especially 30-40 Shore A.

Description

Die vorliegende Erfindung betrifft eine Innensohle mit einer dem Umriss eines Schuhs entsprechenden, flachen Grundsohle aus elastischem Schaumstoffmaterial, die auf ihrer oberen Seite mehrere ebenfalls aus elastischem Schaumstoffmaterial bestehende, integral angeformte Erhebungen im Bereich von Reflexzonen der Fusssohle aufweist.The present invention relates to an insole with a the outline of a shoe corresponding, flat bottom sole made of elastic foam material, which on its upper Side several also made of elastic foam material existing, integrally formed surveys in the area of Has reflex zones of the sole of the foot.

Unter dem Begriff Innensohle wird hier einerseits eine mit einer Schuhsohle fest verbundene Innensohle verstanden, wie auch eine lose darauf aufgelegte Innensohle, die auch als Einlegesohle bezeichnet wird. Innensohle ist ein genereller Begriff unter dem auch Brandsohlen und Decksohlen verstanden werden.The term insole is here on the one hand with a a shoe sole firmly connected insole understood how also a loosely applied insole, which also as Insole is called. Insole is a general one Term under the insole and insoles understood become.

Innensohlen, die mit zur Reflexzonenmassage geeigneten Erhebungen versehen sind, sind in verschiedensten Ausführungsformen bekannt. Die Mehrzahl solcher Innensohlen weisen eine über die gesamte Oberfläche angeordnete genoppte Auflagefläche auf, wobei die Oberflächenstruktur der Innensohle durch die Gesamtheit der Noppen gebildet wird. Innensohlen dieser Art zeigen beispielsweise die EP-0'225'285 und die US-4,760,655 A. Während im letzteren Fall gleich wie bei der CH-686'062 A die Noppenhöhe über die gesamte Fläche der Einlegesohle gleichbleibend gestaltet ist, sind andere Innensohlen, wie beispielsweise gemäss der WO 85/04786 mit Noppen gestaltet, deren Höhe variiert und die entsprechend praktisch ein Fussbett bilden. Innensohlen dieser Art bewirken praktisch immer eine Ueberreizung der Fusssohle, womit die gewünschte Fussreflexzonenmassage nicht mehr die erwünschte Wirkung zeigt. Vielmehr führt die Ueberreizung zu Blockaden der Nervenleitungen und zu schädlichen Folgen. Korrekterweise verweisen entsprechende Anbieter darauf, dass solches Schuhwerk nur während 1-2 Stunden getragen werden sollte.Insoles that are suitable for reflexology Surveys are provided in various ways Embodiments known. The majority of such insoles have a pinned over the entire surface arranged Support surface, wherein the surface structure of the Insole is formed by the totality of the knobs. Insoles of this type are shown for example in EP-0'225'285 and US-4,760,655 A. While in the latter case the same as in the case of CH-686'062 A, the nub height over the entire surface the insole is designed consistently, are others Insoles, such as according to WO 85/04786 with Nubs designed whose height varies and the corresponding practically form a footbed. Insoles of this type effect almost always an overstressing of the sole of the foot, with which the desired foot reflexology massage no longer the shows desired effect. Rather, the over-stimulation leads to Blockages of nerve lines and harmful consequences. Correctly, appropriate providers point out that Such footwear will only be worn for 1-2 hours should.

Bezüglich der Herstellung von Innensohlen mit Erhebungen aus elastischem Schaumstoffmaterial sind zwei Konstruktionsprinzipien bekannt. Im einen Fall wird von einer härteren Grundsohle ausgegangen und darauf kissenförmige Erhebungen aufgeklebt. Dies ist eine äusserst aufwendige und teure Fertigungsweise. Diese Fertigungsweise ist beispielsweise aus der bereits erwähnten US-4,760,655 A bekannt. Damit die Erhebungen noch eine relevante Massagewirkung erzielen, müssen sie relativ stark gegenüber der Grundfläche vorstehen. Wegen der genoppten Deckschicht, die darüber angebracht wird und sich über die gesamte Innensohle erstreckt wird praktisch unerwünschterweise die Massage in den härteren, nicht erhöhten Bereichen stärker wahrgenommen als in den erhöhten Bereichen.Regarding the production of insoles with protrusions elastic foam material are two design principles known. In one case, the harder one The bottom of the sole and then pillow-shaped elevations glued. This is a very elaborate and expensive Production method. This production method is for example off the already mentioned US-4,760,655 A known. So that Surveys still achieve a relevant massage effect, they must protrude relatively strong against the base. Because of the studded top layer that is attached over it and extending over the entire insole becomes practical undesirably the massage in the harder, not elevated areas perceived stronger than in the elevated Areas.

Aus der DE-90'02'962.3 U ist eine den Oberbegriff des Patentanspruches 1 bildende Innensohle bekannt. Hierbei sind die Grundsohle und die Erhebungen integral einheitlich aus einem Schaumstoffmaterial mit einer Härte von 30° bis 45° Shore A gefertigt. Vorzugsweise wird diese Innensohle aus Kunststoff gefertigt. Sie kann sowohl als Einlegesohle als auch als Innensohle angeordnet sein. Bei dieser bekannten Innensohle sind sowohl die Grundsohle als auch die Erhebungen aus einem vorzugsweise synthetischen Material gefertigt. Latex als ein Naturprodukt hat klassischerweise eine Härte von Shore A von 10-20. Es lässt sich zwar auf grössere Härten einstellen, doch verteuert dies einerseits das Produkt und andererseits sind die Beimischungen teilweise physiologisch unerwünscht.From DE-90'02'962.3 U is a the preamble of Patent claim 1 forming insole known. Here are the sole and elevations are integrally uniform a foam material with a hardness of 30 ° to 45 ° Shore A made. Preferably, this insole is made Made of plastic. It can be used both as an insole be arranged as an insole. In this known Insole are both the bottom sole and the elevations made of a preferably synthetic material. Latex as a natural product has a hardness classically from Shore A from 10-20. It can be set to greater hardness but on the one hand this increases the price of the product and On the other hand, the admixtures are partially physiological undesirable.

Am besten liesse sich eine sanfte und wirksame Fussreflexzonenmassage erzielen wenn es gelingt, eine in der Wahrnehmung weiche Innensohle mit einer gewissen Einsinktiefe und einer genügenden Federtiefe zu schaffen, damit harte Stösse vermindert via Reflexzonenmassagepunkte auf die Fusssohle übertragen werden. The best would be a gentle and effective Achieve reflexology if it succeeds in the Perception soft insole with a certain sinking depth and to create a sufficient spring depth, so hard Bumps reduced via reflexology massage points on the Sole be transferred.

Die vorliegende Erfindung stellt sich daher die Aufgabe, eine Innensohle der eingangs genannten Art zu schaffen unter Meidung der vorgenannten Nachteile und bei gleichzeitiger Erzielung des vorbeschriebenen Effektes.The present invention therefore has as its object, a Insole of the type mentioned above to create Avoiding the aforementioned disadvantages and at the same time Achievement of the above-described effect.

Diese Aufgabe löst eine Innensohle mit den Merkmalen des Patentanspruches 1. Dank der kombinatorischen Wahl der Materialien mit der entsprechenden Härte ergibt sich ein Produkt mit hervorragenden physiologischen Eigenschaften, das zudem einfach zu fertigen ist.This task triggers an insole with the characteristics of the 1. Thanks to the combinatorial choice of Materials with the appropriate hardness results Product with excellent physiological properties, that Moreover, it is easy to manufacture.

Verwendet man Leder zur Fertigung der Deckschicht, so lässt sich einerseits die gewünschte Gesamthärte gut einstellen und erzielt zudem eine sich hervorragendst verbindende Materialkombination. Weitere vorteilhafte Ausgestaltungsformen gehen aus den abhängigen Ansprüchen hervor und deren Wirkungsweise und Bedeutung ist in der nachfolgenden Beschreibung erläutert. In der Zeichnung ist ein bevorzugtes Ausführungsbeispiel des Erfindungsgegenstandes dargestellt und in der nachfolgenden Beschreibung im Detail erklärt. Es zeigt:

If one uses leather for the production of the cover layer, then on the one hand the desired total hardness can be adjusted well and achieves in addition a combination of material which combines with outstanding results. Further advantageous embodiments will become apparent from the dependent claims and their mode of action and meaning is explained in the following description. In the drawing, a preferred embodiment of the subject invention is illustrated and explained in detail in the following description. It shows:

Mit der Bezugszahl 1 ist die Innensohle als Ganzes bezeichnet. Sie besteht aus einer flachen Grundsohle 2 aus elastischem Schaumstoffmaterial im vorliegenden Fall aus Latex oder Polyurethan. Auf der oberen Seite der flachen Grundsohle 2 sind mehrere einstückig mit der Grundsohle 2 gefertigte, aus demselben Material bestehende und somit integral angeformte Erhebungen 3 erkennbar. Diese Erhebungen 3 befinden sich in den bekannten Bereichen von Reflexzonen der Fusssohle. Die Erhebungen 3 sind so gestaltet, dass sie seitlich nach oben geneigt verlaufend sind und eine zentrale ebene Fläche 5 aufweisen. Zwischen der zentralen Ebene 5 und der nicht erhöhten Oberfläche der Grundsohle 2 befinden sich die umlaufenden seitlichen Neigungen 4. Diese Gestaltungsweise hat den Sinn, dass die Innensohle nicht nur während des Gehens zur Massage der Reflexzonen dient, sondern auch im Ruhezustand eine Akupressurwirkung erzielt, die besonders sanft wirkt.The reference numeral 1 is the insole as a whole designated. It consists of a flat bottom sole 2 elastic foam material in the present case Latex or polyurethane. On the upper side of the flat Basic sole 2 are several integral with the sole 2 manufactured, made of the same material and thus integrally molded elevations 3 recognizable. These surveys 3 are in the known areas of reflex zones the sole of the foot. The surveys 3 are designed to be are inclined laterally upwards and a central have flat surface 5. Between the central level 5 and The non-elevated surface of the bottom sole 2 are located the circumferential lateral inclinations 4. These Design style has the sense that the insole is not only while walking serves to massage the reflex zones, but achieved an acupressure effect even when at rest, the looks very gentle.

Die Erhebungen brauchen keineswegs lediglich eine kreisrunde Gestalt zu haben sondern können auch, wie dies die Figur 2 zeigt, beliebige andere Ausgestaltungsformen haben. Insbesondere könnend die Erhebungen auch linienförmig sein. Eine solche linienförmige Erhebung 6 ist in der Figur 2 dargestellt. Die linienförmige Erhebung hat eine Scheitellinie, die auf gleichbleibender Höhe verläuft. Im Normalfall sind sämtliche Erhebungen gleich stark über der Oberfläche der Grundsohle 2 nach oben vorstehend.The surveys do not need only a circular To have shape but also, like this the figure 2 shows, have any other embodiments. In particular, the elevations may also be linear. Such a linear elevation 6 is shown in FIG. 2 shown. The linear survey has one Crest line, which runs at a constant height. in the Normally, all surveys are equally strong over the Surface of the bottom sole 2 projecting above.

Die Grundsohle 2 besteht aus einer geschäumten elastischen Materialschicht, hier einer Latexschicht 10 und einer darüber angeordneten, fest verbundenen Deckschicht 20. Die geschäumte Materialschicht weist eine Härte von 10°- 20° Shore A auf. Wegen der relativ geringen Dicke der Latexschicht 10, die im Bereich ohne Erhöhungen zwischen 1,5 mm und 4,0 mm beträgt, wirken sich die bei Latex durchaus auftretenden relativ grossen Härteunterschiede stark aus. Dies hat unter anderem auch damit zu tun, dass die Porengrösse örtlich variieren kann. Diese Unterschiede bleiben auch dann bestehen, wenn ein Latex mit höherer Shore-Härte verwendet wird. Gemäss der Erfindung wird nun eine Materialpaarung vorgeschlagen, die diese Unterschiede weitgehend behebt und insgesamt zu einer klarer definierbaren Härte führt, die den gewünschten Eigenschaften entspricht. Im Gegensatz zu bekannten Sohlen, bei denen lediglich im Bereiche der Reflexzonen Erhebungen aus weichem Polstermaterial angebracht werden, entsteht eine insgesamt besser gedämpfte Sohle im Vergleich zu der bekannten, die extreme Härteunterschiede im Bereich der Erhebungen und in den Bereichen neben den Erhebungen aufweist.The basic sole 2 consists of a foamed elastic Material layer, here a latex layer 10 and one above arranged, firmly bonded cover layer 20. The foamed Material layer has a hardness of 10 ° - 20 ° Shore A. Because of the relatively small thickness of the latex layer 10, which in the Range without elevations between 1.5 mm and 4.0 mm, The effects of latex are quite relative strong differences in hardness. This has, among other things Also to do with the fact that the pore size vary locally can. These differences persist even if one Latex with higher Shore hardness is used. According to the Invention is now proposed a material pairing, the these differences largely remedies and overall one clearly definable hardness leads to the desired Properties corresponds. Unlike known soles, in which only elevations in the areas of reflex zones made of soft padding material, creates a overall better damped sole compared to the well-known, the extreme hardness differences in the field of Surveys and in the areas adjacent to the surveys having.

Die Grunddicke der Latexschicht, bzw. der geschäumten Materialschicht kann hier dank der Kombination mit einer Deckschicht praktisch jede beliebige Dicke aufweisen. Hierbei wird man bei der Wahl der Dicke bei Innensohlen, die fest mit dem Schuhwerk verbunden sind, eher eine dickere, bei Einlegesohlen eher eine dünnere Ausstattung wählen. Prinzipiell muss jedoch bei einer grösseren Dicke der Innensohle auch die absolute Höhe der Erhebungen grösser sein, um so das Eintauchen zu kompensieren. The basic thickness of the latex layer, or the foamed Material layer can here thanks to the combination with a Cover layer have virtually any thickness. in this connection One is in choosing the thickness of insoles, the firm with connected to the footwear, rather a thicker, at Insoles tend to choose a thinner outfit. In principle, however, with a greater thickness of the Insole also the absolute height of the surveys larger so as to compensate for the dipping.

Besonders vorteilhaft hat es sich erwiesen, die Deckschicht aus Leder zu gestalten. Hierbei ist einerseits eine hohe Flexibilität erwünscht, um die Beweglichkeit der Oberfläche der gesamten Innensohle 1 zu gewährleisten und andererseits soll die Haftwirkung zwischen der geschäumten Materialschicht, z.B. Latexschicht 10 und der Deckschicht 20 möglichst mit physiologisch unbedenklichem Haftverbinder erzielbar sein. Dies lässt sich bei der Verwendung von Leder als Deckschicht erzielen. Besonders vorteilhaft ist es dabei, die Deckschicht aus Spaltleder zu fertigen. Spaltleder ist nicht nur preislich interessant, sondern hat den Vorteil einer gleichbleibenden Dicke über die gesamte Fläche und einer besonders uniformen Weichheit im Griff. Spaltleder formt sich entsprechend bei der Herstellung auch aussergewöhnlich gut der Kontur der Herstellungsformen an. Dies erlaubt auch, die Höhe der Erhebungen in der geschäumten Materialschicht ein bis zweimal der Dicke ausserhalb der Bereiche der Erhebungen entsprechend zu gestalten. Mit Spaltleder lässt sich auch das optimale Dickenverhältnis zwischen der geschäumten Materialschicht und der Deckschicht praktisch beliebig einstellen. Entsprechend kann somit auch die gewünschte Gesamthärte der Innensohle auf wenige Grad Shore A Härte eingestellt werden. Erfindungsgemäss erfolgt die Einstellung auf eine Härte von über 25° Shore A, die insbesondere, zwischen 30° und 40° Shore A liegt. It has proven to be particularly advantageous for the cover layer made of leather. On the one hand, this is a high one Flexibility desirable to the mobility of the surface to ensure the entire insole 1 and on the other should the adhesive effect between the foamed Material layer, e.g. Latex layer 10 and the cover layer 20 if possible with physiologically harmless adhesive connector be achievable. This can be done with the use of leather achieve as a cover layer. It is particularly advantageous to manufacture the top layer of split leather. Split leather is not only priced interesting, but has the advantage a constant thickness over the entire surface and a particularly uniform softness in the handle. Split leather forms accordingly in the production as well Exceptionally well to the contour of the manufacturing forms. This also allows the height of the elevations in the foamed Material layer one to two times the thickness outside the To design areas of the surveys accordingly. With Split leather can also be the optimal thickness ratio between the foamed material layer and the cover layer practically arbitrary. Accordingly, therefore, too the desired total hardness of the insole to a few degrees Shore A hardness can be adjusted. According to the invention takes place the attitude to a hardness of over 25 ° Shore A, in particular, between 30 ° and 40 ° Shore A is lying.

Bei exklusiveren Ausführungen wird man jedoch eher das teurere Oberleder verwenden und entsprechend eine Auswahl von Leder diverser Härten an Lager legen.For more exclusive versions, but you will rather that use more expensive upper leather and accordingly a choice of Leather of various hardnesses in stock.

Während bisher Innensohlen entweder aus einem einzigen Material, welches die gewünschte Endhärte aufwies, gefertigt wurden oder aber Materialpaarungen vorgesehen wurden, die über die gesamte Oberfläche gesehen Bereiche unterschiedlicher Härten ergaben, zeigt die Erfindung erstmals eine Lösung auf, bei der die Härteeinstellung aus zwei Materialien bewirkt wird, die über die gesamte Fläche der Grundsohle 2 je für sich gleichbleibend sind, jedoch in ihrer Paarung eine gewünschte Endhärte ergeben, die nicht der Härte eines der beiden Materialien entspricht. Hierbei ist die Materialwahl sowohl aus ökologischer als auch aus ökonomischer Sicht vorteilhaft. Es kann eine relativ dünne Schicht aus Latex verwendet werden und hierbei ein Latex mit relativ tiefer Dichte und entsprechender geringer Shore A-Härte, das entsprechend preiswert auf dem Markt erhältlich ist, gewählt werden und andererseits ein Spaltleder genommen werden, welches eine gute Einstellung der Materialpaarung erlaubt.While so far insoles either from a single Material, which had the desired final hardness manufactured were or were provided material pairings, the Over the entire surface seen areas of different Hardening showed, the invention shows a first Solution on which the hardness setting of two materials is effected over the entire surface of the sole 2 ever are consistent, but in their mating one desired final hardness, not the hardness of one of corresponds to both materials. Here is the choice of material both from an ecological and economic point of view advantageous. It can be a relatively thin layer of latex used and in this case a latex with relatively deeper Density and corresponding low Shore A hardness, the appropriately priced on the market, selected and on the other hand a split leather are taken, which allows a good adjustment of the material pairing.

Die geschäumte Materialschicht kann wie erwähnt auch aus Polyurethanschaum gefertigt sein. Hier wird man bevorzugterweise auch einen Härtegrad ähnlich einem natürlichen Latexschaum wählen. Es ist aber auch möglich, die geschäumte Materialschicht aus zwei Materiallagen zu fertigen, wie dies die Figuren 4 und 5 zeigen.The foamed material layer can also be made as mentioned Polyurethane foam be made. Here you become preferably also a hardness similar to one choose natural latex foam. But it is also possible that foamed material layer of two material layers too finished, as shown in Figures 4 and 5.

Eine dünne Latexschicht 10 sowie eine Deckschicht 20 aus Leder haben beispielsweise eine Wasserdampfdurchlässigkeit gemessen nach DIN 53333 von 6,9 mg/cm2. Dies bedeutet, dass die erfindungsgemässe Sohle eine relativ gute Schweissabsorption zulässt. Die Sohle hat zudem eine Luftdurchlässigkeit von 8,5 l/min. bei 0,01 bar. Folglich erlaubt die erfindungsgemässe Innensohle über Nacht eine Schweissabgabe. Diese gewünschten Effekte bedeuten aber auch eine relativ geringe Wärmedämmung. Erfindungsgemäss lässt sich dies drastisch reduzieren, indem man unterhalb der Latexschicht eine Schicht aus geschäumtem Polyurethan anbringt oder die gesamte geschäumte Materialschicht aus diesem Material fertigt. Versuche haben gezeigt, dass sich hierfür insbesondere ein antibakteriell und antifungizid behandeltes Polyurethan mit der Bezeichnung Sanitized® PUR 99-45 eignet. Dieses Material wird in der Schweiz von der Firma Clariant Huningue SA in Frankreich angeboten. Es handelt sich dabei um ein Material mit einer Härte von 20 bis 24 Shore C gemessen analog der Methode nach DIN 53505. Diese Polyurethanschicht mit einer Dicke von 4-7 mm erzeugt eine ausgezeichnete Wärmedämmung. Die Gesamtwirkung der Sohle bezüglich ihres Massageeffektes beziehungsweise Akupressureffektes bleibt trotz der relativ weichen Polyurethanschicht 30 erhalten. A thin latex layer 10 and a cover layer 20 made of leather, for example, have a water vapor permeability measured according to DIN 53333 of 6.9 mg / cm 2 . This means that the sole according to the invention allows a relatively good absorption of perspiration. The sole also has an air permeability of 8.5 l / min. at 0.01 bar. Consequently, the insole according to the invention permits a sweat delivery overnight. However, these desired effects also mean a relatively low thermal insulation. According to the invention, this can be drastically reduced by applying a layer of foamed polyurethane below the latex layer or by manufacturing the entire foamed material layer from this material. Experiments have shown that in particular an antibacterial and antifungal treated polyurethane called Sanitized® PUR 99-45 is suitable. This material is offered in Switzerland by Clariant Huningue SA in France. It is a material with a hardness of 20 to 24 Shore C measured analogous to the method according to DIN 53505. This polyurethane layer with a thickness of 4-7 mm produces excellent thermal insulation. The overall effect of the sole with respect to its massage effect or acupressure effect is maintained despite the relatively soft polyurethane layer 30.

Unter der geschäumten Schicht, die ein oder zweilagig sein kann, wird man bevorzugterweise bei der Verwendung als integrierbare Innensohle eine Texon-, Korkschrot- oder Zellstoffschicht 40 anbringen. Diese Schicht 40 ist relativ hart. Sie kann gleichzeitig als Brandsohle zum Montieren von Schäften dienen.Under the foamed layer, which may be one or two layers can, is preferably when using as integrable insole a Texon, Korkschrot- or Apply pulp layer 40. This layer 40 is relative hard. It can also be used as an insole to mount Serve shanks.

Die relative Härte der Schicht 40 schützt die Innensohle mechanisch gegenüber Unebenheiten der Schuhsohleninnenseite. Sie dient somit auch als Teil der Brandsohle.The relative hardness of the layer 40 protects the insole mechanically against unevenness of the shoe sole inside. It also serves as part of the insole.

Bei der Wahl von zweilagigen Innensohlen aus der Kombination von Latex und Polyurethan wird man bevorzugterweise die Latexschicht über der Polyurethanschicht kaschieren. Auch wenn als Polyurethanschaum ein Sanitized® PUR 99-45 verwendet wird, so vermag die antibakterielle und antifungizide Wirkung durch die Latexschaumschicht wahrgenommen zu werden.When choosing two-ply insoles from the combination of latex and polyurethane is preferably the Coat the latex layer over the polyurethane layer. Also if the polyurethane foam is a Sanitized® PUR 99-45 becomes, so can the antibacterial and antifungal effect to be perceived by the latex foam layer.

Neben den Ausführungen gemäss den Figuren 1 und 2 sind verschiedenste andere Erhebungsformationen zur gezielten Beeinflussung verschiedener Reflexzonen zur Einwirkung auf entsprechende Organe oder Körperbereiche denkbar. Während bisher praktisch nur Innensohlen mit einer allgemein anwendbaren Anordnung der Erhebungen üblich waren, können Innensohlen mit den erfindungsgemässen Gestaltung wesentlich besser und präziser gefertigt werden und daher kann erstmals eine ganze Palette von Innensohlen mit gezielter Beeinflussung bestimmter Organe oder Körperbereiche zur Auswahl geboten werden. So zeigt Figur 6 eine Anordnung der Erhebung, die den Kreuzbereich beeinflusst, Figur 7 eine Anordnung, die auf die Sexualorgane wirkt und Figur 8 eine Anordnung, bei der die Fussreflexzonen beeinflusst werden, die auf den Wirbelsäulenbereich wirken. Figur 9 ist eine Innensohle, die zur Beeinflussung in Schultergürtel und Beckenbereich dient, während Figur 10 eine Anordnung offenbart zur Einflussnahme auf die Verdauungsorgane. Letztlich ist in der Figur 11 eine Innensohle zur Einwirkung auf das vegetative Nervensystem gezeigt.In addition to the embodiments according to Figures 1 and 2 are various other survey formations for targeted Influencing different reflex zones to influence appropriate organs or body areas conceivable. While so far practically only insoles with a general the usual arrangement of the surveys were common Insoles with the inventive design essential be made better and more precise and therefore can for the first time a whole range of insoles with targeted Influencing certain organs or areas of the body Selection to be offered. Thus, Figure 6 shows an arrangement of Elevation affecting the cross area, Figure 7 a Arrangement that acts on the sexual organs and Figure 8 a Arrangement in which the foot reflex zones are influenced, which act on the spine area. FIG. 9 is a Insole, which can be used to influence shoulder belts and Pelvic area is used while Figure 10 is an arrangement discloses to influence the digestive organs. Finally, in Figure 11 is an insole for action shown on the autonomic nervous system.

Wegen der bei den heute üblichen Innensohlen bewirkten Überreizung waren solche Innensohlen nicht anbietbar, ohne dabei eventuelle Schädigungen in Kauf zu nehmen. Because of the usual soles used today Over-stimulation, such insoles were not available, without thereby to accept possible damages.
