It would even be conceivable to simply cut off the front end of the sole on certain feet or shoes where the sole extends too far forward in the small toe area, which in no way can cause problems, since the small toe then lies completely on the sole and therefore one any edge that may result from cutting cannot lead to pressure marks.

Abstract

The invention relates to a foot-supporting insole of which the front bounding line (24) extends in front of the ball (28) of the little toe at the outside of the foot and behind the ball (27) of the big toe at the inside of the foot. To enable such an insole to be used in all conventionally marketed shoes and to ensure that correct adaptation to the foot of the wearer will not be necessary, it is suggested to make the insole (2) of resiliently elastic material of substantially constant thickness and to construct it so that it is curved upwardly at the inside (3) of the foot, the stiffness of the insole (2) at least at the outside zone of the foot being so high that the foot rotatingly rolls towards the big toe during walking. Preferably, the length of the insole (2) at the inside of the foot corresponds to a size which is several sizes smaller than the measurement corresponding to the length at the outside of the foot.

Description

Die Erfindung betrifft eine fußstützende Sohle, die sich vom Fersenbereich bis zu einer 5-förmigen vorderen Begrenzungslinie erstreckt, welche an der Fußaußenseite vor dem Kleinzehenballen und an der Fußinnenseite hinter dem Großzehenballen verläuft, die weiter zur Unterstützung des Fußgewölbes an der Fußinnenseite nach oben gewölbt ist und deren Steifheit zumindest im Bereich der Fußaußenseite so groß ist, daß der Fuß bei der Abrollbewegung während des Laufens in Richtung auf die Großzehe verdreht wird. Eine Anwendung der Sohle nach der Erfindung ist bei entsprechender Ausgestaltung sowohl als Einlegesohle als auch als Zwischensohle oder Brandsohle zum festen Einbau in Schuhe möglich.The invention relates to a foot-supporting sole that extends from the heel area to a 5-shaped front boundary line, which runs on the outside of the foot in front of the ball of the toe and on the inside of the foot behind the ball of the big toe, which is further arched upward to support the arch of the foot on the inside of the foot and whose stiffness is so great, at least in the area of the outside of the foot, that the foot is rotated in the direction of the big toe during the rolling movement while walking. An application of the sole according to the invention is possible with an appropriate design both as an insole and as a midsole or insole for permanent installation in shoes.

Schuhwerk sollte möglichst so beschaffen sein, daß es einerseits im Stand eine natürliche Auflagefläche für den Fuß bildet, andererseits jedoch auch die natürliche Abrollbewegung des Fußes während des Laufens nicht behindert sondern sie nach Möglichkeit unterstützt. Dabei müsste im Stand die Möglichkeit bestehen, daß der Großzehballen etwas tiefer liegt als der Kleinzehballen, wobei zudem das Gelenk des Fußes, insbesondere wenn man längere Zeit steht, entsprechend unterstützt sein sollte. Beim Laufen erfolgt die natürliche Abrollbewegung des Fußes zunächst als Auftritt des Fersenbeines. Anschließend sollte der Fuß so abrollen, daß die Abrollbewegung deutlich auf die Großzehe, zu, d.h. nach vorne und innen, gerichtet ist. Die Großzehe selbst muß gerade nach vorne abgerollt werden. Die vorstehenden Voraussetzungen waren weitgehend bei dem bis vor einiger Zeit gebräuchlichen Rahmenschuhwerk bekannt. Infolge der Härte bzw. Steifheit des Rahmens erhielt die Abrollbewegung während des Laufens die vorstehend angegebene, günstige Richtung. Außerdem hatte der Fuß die Möglichkeit, sich durch Verdrängung der Ausballmasse ein beim Stand und während des Laufens günstiges Fußbett zu schaffen. Rahmenschuhe werden jedoch neuerdings nicht mehr oder nur noch in sehr untergeordnetem Umfange gefertigt, da ihre Herstellungskosten zu hoch sind. Man geht nun im wesentlichen zu Schuh-Macharten über, bei denen ebene, verhältnismäßig harte Brandsohlen und ebene Laufsohlen vorgesehen sind, die im Vorderteil nach allen Seiten gleich biegsam ausgebildet werden. Dieses Fußbett führt zu einer unnatürlichen Absenkung der Kleinzehe und als Folge davon zu einem Abrollen des Fußes über die Kleinzehe nach außen. Um dieser Abrollrichtung folgen zu können, dreht sich häufig die Großzehe nach außen, was eine der Hauptursachen von Fußerkrankungen, insbesondere des Hallux-Valgus, ist. Wird der Hallux-Valgus operativ behoben, so muß ein Schuh getragen werden, bei dem nach Möglichkeit ein Abrollen nach außen verhindert ist, um nicht erneut entsprechende Beschwerden auftreten zu lassen. Bisher sind jedoch keine Schuhe - abgesehen von den erwähnten Rahmenschuhen - bekannt, die diese Forderung aufgrund ihrer Machart erfüllen.If possible, footwear should be designed so that on the one hand it forms a natural contact surface for the foot when standing, but on the other hand it does not hinder the natural rolling movement of the foot while running but supports it if possible. The stand should have the possibility that the big toe ball is slightly lower than the small toe ball, whereby the joint of the foot, especially if you stand for a long time, should be supported accordingly. When running, the natural rolling movement of the foot initially occurs as a step on the heel bone. Then the foot should roll in such a way that the rolling movement clearly towards the big toe, i.e. forward and inward. The big toe itself must be rolled straight forward. The above requirements were largely known for the frame footwear that had been in use until some time ago. As a result of the hardness or rigidity of the frame, the rolling movement was given the favorable direction indicated above during running. In addition, the foot had the option of creating a footbed that was good for standing and running by displacing the ball mass. Recently, frame shoes are no longer manufactured or only to a very minor extent, since their manufacturing costs are too high. One now proceeds essentially to shoe designs, in which flat, relatively hard insoles and flat outsoles are provided, which are designed to be equally flexible in all directions in the front part. This footbed leads to an unnatural lowering of the small toe and, as a result, to an unrolling of the foot over the small toe. In order to be able to follow this rolling direction, the big toe often turns outwards, which is one of the main causes of foot diseases, especially of the hallux valgus. If the hallux valgus is surgically corrected, a shoe must be worn which, if possible, prevents it from rolling outwards in order not to cause complaints again. So far, however, no shoes - apart from the frame shoes mentioned - are known to meet this requirement due to their design.

Abhilfe kann hier unter Umständen durch eine Sohle geschaffen werden, wie sie aus der DE-C-847 716 bekannt ist. Bei der bekannten Sohle, die sowohl als lose Einlage als auch fest in den Schuh eingearbeitet verwendet werden kann, ist die vordere Begrenzung, die auch bogenförmig, etwa in S-Form verlaufen kann so schräg zur Schuh-Längsachse angeordnet, daß an der Fußaußenseite die Kleinzehe noch ganz auf der Einlage aufruht, während an der Fußinnenseite der Großzehenballen vor der Begrenzungslinie zu liegen kommt. Bei einer derartigen Gestaltung der Einlage wird sicherlich der Großzehenballen den eingangs erwähnten Forderungen entsprechend gegenüber dem Kleinzehenballen tiefer gelegt und dadurch in gewissem Umfang ein Abrollen in Richtung auf die Großzehen begünstigt. Die bekannte Einlage hat aber ebenfalls eine Vielzahl von Mängeln. Wohl der gravierendste Mangel besteht darin, daß die bekannte Einlage relativ dick ist und insbesondere so gestaltet, daß ihre Dicke an der Fußaußenseite wesentlich größer ist als an der Fußinnenseite. Infolgedessen kann die Einlage nur in besonders gestaltetes Schuhwerk eingearbeitet werden, das ausreichende Weite besitzt. Darüber hinaus steht der Fuß nicht nur in seinem vorderen Bereich sondem insgesamt leicht nach innen, wodurch das Fußgelenk unnatürlich beansprucht und infolgedessen die Bildung von Senk- oder Spreizfüßen begünstigt wird. Ein weiterer Mangel ist darin zu sehen, daß die bekannte Einlage infolge ihrer unverhältnismäßig großen Dicke im allgemeinen nahezu vollständig steif sein wird, so daß die Abrollbewegung des Fußes in dem Bereich zwischen der Ferse und den Ballen erheblich erschwert wird.This can be remedied by a sole, as is known from DE-C-847 716. In the known sole, which can be used both as a loose insert and firmly incorporated into the shoe, the front boundary, which can also run in an arc shape, approximately in an S-shape, is arranged so obliquely to the longitudinal axis of the shoe that the outside of the foot The small toe still rests completely on the insert, while the big toe ball lies on the inside of the foot in front of the boundary line. With such a design of the insert, the big toe ball is certainly lowered according to the requirements mentioned above compared to the small toe ball and thus to a certain extent favors a roll in the direction of the big toe. The well-known insert also has a number of shortcomings. Probably the most serious deficiency is that the known insert is relatively thick and in particular designed so that its thickness on the outside of the foot is much greater than on the inside of the foot. As a result, the insert can only be incorporated into specially designed footwear that has sufficient width. In addition, the foot is not only slightly inward, not only in its front area, as a result of which the ankle is subjected to an unnatural strain and, as a result, the formation of flat or spreading feet is promoted. Another shortcoming is that the known insert will generally be almost completely stiff due to its disproportionate thickness, so that the rolling movement of the foot in the area between the heel and the ball of the heel is made considerably more difficult.

Ein weiterer Mangel der bekannten Einlage ist auch darin zu sehen, daß sie jeweils genau an die Fußgröße angepaßt werden muss, und zwar insbesondere wegen der relativ großen Dicke, die zu Druckstellen oder degleichen führen könnte, wenn die vordere Begrenzungslinie der Sohle nicht an der jeweils günstigsten Stelle liegt.Another shortcoming of the known insert is that it has to be adapted precisely to the size of the foot, in particular because of the relatively large thickness, which could lead to pressure points or the like if the front boundary line of the sole is not at the respective cheapest place.

Bei der Schuheinlage gemäß DE-C-691 306 wird ein Teil der vorerwähnten Mängel ausgeschaltet. Die bekannte Schuheinlage ist insbesondere so ausgebildet, daß in Ruhestellung keine unnatürliche Schrägstellung des Fußes eintritt. Trotzdem wird wegen der Steifheit der Einlage im Bereich der Fußaußenseite und aufgrund des Umstandes, daß dort wenigstens der Kleinzehenballen erfaßt ist, erreicht, daß während des Laufens eine natürliche, auf die Großzehe zu gerichtete Abrollbewegung des Fußes eintritt. Die bekannte Einlage kann außerdem verhältnismäßig dünn ausgebildet werden, insbesondere wenn gemäß einem der Ausführungsbeispiele an der Fußaußenseite eine Versteifungseinlage vorgesehen ist. Infolge dieses Umstandes ist es somit auch möglich, die bekannte Einlage in normalen Schuhen zu verwenden. Bei Verwendung einer Sohle gemäß der DE-C-691 306 lassen sich etliche Erkrankungen verhindern bzw. zumindest in ihrere Wirkung abschwächen, beispielsweise ist die Bildung eines Hallux-Valgus praktisch ausgeschlossen. "Digitus-Quintus", Hühneraugen an der Kleinzehen und verhärtete Haut können ebenfalls weitgehend verhindert werden. Auch ist eine postoperativ Versorgung von operierten Füßen erleichtert.With the shoe insert according to DE-C-691 306, some of the aforementioned defects are eliminated. The known shoe insert is particularly designed so that no unnatural inclination of the foot occurs in the rest position. Nevertheless, due to the stiffness of the insert in the area of the outside of the foot and the fact that at least the ball of the toe is covered there, it is achieved that a natural rolling movement of the foot directed towards the big toe occurs during running. The known insert can also be made relatively thin, especially if, according to one of the exemplary embodiments, a stiffening insert is provided on the outside of the foot. As a result of this fact, it is also possible to use the known insert in normal shoes. When using a sole according to DE-C-691 306, a number of diseases can be prevented or at least weakened in their effect, for example the formation of a hallux valgus is practically impossible. "Digitus-Quintus", corns on the small toes and hardened skin can also be largely prevented. Postoperative care of operated feet is also facilitated.

Trotz der vorerwähnten Vorzüge hat die bekannte Schuheinlage jedoch auch etliche Mängel. In der Normalausführung ist diese Einlage nämlich derart gestaltet, daß sie die gesamte Shlehfläche des Schuhes ausfüllt, wobei die höhere Steifheit im Bereich der Fußaußenseite durch eine Verstärkungseinlage erreicht wird. Ein derartiges Vorgehen hat zum einen den Nachteil, daß eine genaue Anpassung der Größe der Schuheinlage an die jeweilige Schuhgröße und -form erfolgen muß. Dies bedeutet aber, daß es erforderlicht ist, in entsprechenden Geschäften jeweils eine Vielzahl von unterschiedlichen Größen der bekannten Schuheinlage vorrätig zu halten, um sämtliche Bedürfnisse erfüllen zu können. Der dadurch bedingte Fertigungs- und Lageraufwand ist sehr hoch, weshalb vermutlich auch die bekannte Schuheinlage niemals praktisch eingesetzt wurde.Despite the aforementioned advantages, the known shoe insert also has a number of shortcomings. In the normal version, this insert is designed in such a way that it fills the entire shoe surface, the higher stiffness in the area of the outside of the foot being achieved by a reinforcement insert. On the one hand, such a procedure has the disadvantage that the size of the shoe insert must be precisely adapted to the respective shoe size and shape. However, this means that it is necessary to keep a large number of different sizes of the known shoe insert in stock in corresponding shops in order to be able to meet all needs. The resulting manufacturing and storage costs are very high, which is probably why the well-known shoe insert was never used in practice.

In Abbildung 8 der DE-C-691 306 ist dann noch eine Ausführungsform gezeigt, die nicht über die gesamte Schuhlänge reicht. Auch diese Ausführungsform kann jedoch nicht befriedigen, weil die die Abrollachse wesentlich mit bestimmende Vorderkante der Schuheinlage nahezu quer zur Fußlängsachse verläuft. Dies bedeutet aber, daß die an sich angestrebte Abrollbewegung schräg zur Großzehe nicht erreicht werden kann. Weiter ist bei dieser Ausführungsform der bekannten Schuheinlage nachteilig, daß sowohl ihre Herstellung als auch ihr Einbau in den Schuh Schwierigkeiten bereiten, weil der Umriß der Einlage vom natürlichen Umriß der Fußsohle, d.h. dem der Brandsohle des Schuhes, ganz erheblich abweichtFigure 8 of DE-C-691 306 shows an embodiment which does not extend over the entire length of the shoe. However, this embodiment, too, cannot be satisfactory because the leading edge of the shoe insert, which essentially determines the rolling axis, runs almost transversely to the longitudinal axis of the foot. However, this means that the desired rolling movement diagonally to the big toe cannot be achieved. Another disadvantage of this embodiment of the known shoe insert is that both its manufacture and its installation in the shoe present difficulties because the contour of the insert is dependent on the natural contour of the sole of the foot, i.e. that of the insole of the shoe differs considerably

Der Erfindung liegt nun die Aufgabe zugrunde, eine Sohle der eingangs erwähnten Art, wie sie grundsätzlich aus der DE-C-691 306 bekannt ist, derart auszubilden, daß in einwandfreier Weise die gewünschte Abrollgewegung erreicht wird, gleichzeitig aber die Möglichkeit besteht, die Sohle in einfacher Weise bei verschiedenen Schuhgrößen und -formen einsetzen zu können.The invention is based on the object, a sole of the type mentioned, as it is basically known from DE-C-691 306, in such a way that the desired rolling movement is achieved in a flawless manner, but at the same time there is the possibility of the sole can be used in a simple manner with different shoe sizes and shapes.

Zur Lösung dieser Aufgabe wird nach der Erfindung vorgeschlagen, daß die eingangs erwähnte fußstützende Sohle bei im wesentlichen gleicher Dicke über ihre gesamte Fläche aus federelastisch biegbarem Material besteht, und daß die 5-förmige vordere Begrenzungslinie an ihrem Beginn bzw. Ende etwa senkrecht zur Innen- bzw. Außenkante der Sohle verläuft.To achieve this object, it is proposed according to the invention that the foot-supporting sole mentioned at the outset consists of resiliently bendable material over substantially the entire thickness, and that the 5-shaped front boundary line at its beginning or end is approximately perpendicular to the interior. or outer edge of the sole runs.

Wesentlich bei der Sohle nach der Erfindung ist also zum einen, daß sie aus federelastisch biegbarem Material besteht, wodurch im allgemeinen auf besondere Verstärkungseinlagen usw. verzichtet werden kann. Die Sohle läßt sich somit üblicherweise sehr leicht aus Kunststoff, beispielsweise im Wege des Spritzgießens, herstellen. Aufgrund des Umstandes, daß die vordere Begrenzungslinie etwa S-förmig gestaltet ist, d.h. schräg zur Fußlängsachse verläuft, erzielt man zum einen eine einwandfreie Abrollbewegung des Fußes zur Großzehe zu in einer solchen Weise, daß Pronation und Supination zusammengefaßt werden. Darüberhinaus bietet diese Ausgestaltung der vorderen Begrenzungslinie aber auch die Möglichkeit der Verwendung einer Sohlengröße bei unterschiedlichen Fuß- bzw. Schuhgrößen. Es ist nämlich bei einer solchen Sohle möglich, die Begrenzungslinie in einer Weise zu legen, daß auch bei unterschiedlich großen Füßen bzw. unterschiedlichem Größenverhältnis zwischen den Zehen und dem Restfuß keine Druckstellen entstehen können. Es ist ja relativ gleichgültig, wie weit die Sohle unter den Kleinzehenballen bzw. die Kleinzehe reicht bzw. wie weit hinter dem Großzehenballen die Begrenzungslinie verläuft. Insofern kann durch entsprechende Wahl der S-Form die Anpassungsmöglichkeit an unterschiedliche Größen und gleichzeitig die Richtung der Abrollbewegung in weitem Umfange beeinflußt werden.It is therefore essential for the sole according to the invention, on the one hand, that it consists of resiliently bendable material, which generally makes it possible to dispense with special reinforcing inserts, etc. The sole can therefore usually be made very easily from plastic, for example by injection molding. Due to the fact that the front boundary line is approximately S-shaped, i.e. runs diagonally to the longitudinal axis of the foot, on the one hand a perfect rolling movement of the foot towards the big toe is achieved in such a way that pronation and supination are combined. In addition, this configuration of the front boundary line also offers the possibility of using a sole size for different foot or shoe sizes. It is namely possible with such a sole to lay the boundary line in such a way that no pressure points can occur even with feet of different sizes or different size ratios between the toes and the remaining foot. It is relatively unimportant how far the sole extends under the small toe pads or the small toe or how far behind the boundary line runs the big toe pads. In this respect, the possibility of adaptation to different sizes and, at the same time, the direction of the rolling movement can be influenced to a large extent by appropriate selection of the S shape.

Insbesondere für den Fall, daß die Sohle verhältnismäßig dünn sein soll, kann es günstig sein, wenn an der Fußaußenseite eine bis unter den Kleinzehenballen reichende Versteifungseinlage aus elastisch biegbarem Material vorgesehen ist. Diese Einlage kann aus relativ steifem Material bestehen, während die restliche Sohle, die ja keine allzu großen Kräfte aufnehmen muß, demgegenüber infolge ihrer geringen Dicke weich sein kann. Eine derartige Ausbildung ist insbesondere dann vorteilhaft, wenn aus medizinischen Gründen eine kräftige Unterstützung notwendig erscheint, jedoch normales Schuhwerk mit nicht allzu großer Weite getragen werden soll.In particular in the event that the sole is to be relatively thin, it can be advantageous if a stiffening insert made of elastically bendable material and extending below the small toe balls is provided on the outside of the foot. This insert can be made of a relatively rigid material, while the rest of the sole, which does not have to absorb excessive forces, can be soft due to its small thickness. Such a training is particularly advantageous when a strong support appears necessary for medical reasons, but normal footwear with a not too wide width should be worn.

Es wurde bereits oben erwähnt, daß ein erheblicher Mangel der bekannten Einlagen darin zu sehen ist, daß sie an die jeweilige Fußgröße ganz genau angepaßst werden müssen. Dies gilt für praktisch alle bekannten orthopädischen Einlagen, weshalb bisher so vorgegangen wurde, daß diese Einlagen in den entsprechenden Geschäften in einer Vielzahl von relativ eng gestuften Größen vorrätig gehalten wurden, was einen ganz erheblichen Aufwand sowhol beim Hersteller als auch beim Verkäufer bedingt. Sofern derartige Sohlen aus Kunststoff hergestellt werden, mußten beispielsweise Formen in gleicher Abstufung angeschafft werden. Dies hat sehr häufig dazu geführt, daß irgendwelche Extremgrößen nicht hergestellt wurden, weil die Nachfrage zu gering war mit dem Effekt, daß für Leute mit einer entsprechenden Schuhgrösse Einlagen nur nach Mass, d.h. aber entsprechend teuer, hergestellt werden konnten. Selbst wenn aber die Einlagen in entsprechend enger Staffelung vorhanden waren, ergaven sich immer nocht Schwierigkeiten im Hinblick auf die unterschiedliche Gestalt der Füsse, da bei verschiedenen Personen die Zehen im Vergleich zum Rest des Fusses durchaus unterschiedliche Länge haben, während die Einlagen für eine durchschnittliche Zehenlänge bemessen werden mussten. Bei Leuten mit relativ langen Zehen führte dies dann dazu, dass die vordere Begrenzungslinie der Einlage zu weit vorne, d.h. unter die Zehen, zu liegen kam, während bei Leuten mit kurzen Zehen eventuell die Vorderkante der Einlage genau über dem Ballen lief, was zwangsläufig zu Druckstellen und damit Geh-und Stehbeschwerden führt.It has already been mentioned above that a considerable deficiency of the known insoles can be seen in the fact that they have to be adapted very precisely to the respective foot size. This applies to practically all known orthopedic insoles, which is why it has hitherto been the case that these inserts were kept in stock in the corresponding shops in a large number of relatively narrowly graduated sizes, which requires a very considerable outlay both for the manufacturer and for the seller. If such soles are made of plastic, molds had to be purchased in the same gradation, for example. This has very often led to the fact that some extreme sizes were not produced because the demand was too low with the effect that insoles could only be made to measure, ie correspondingly expensive, for people with a corresponding shoe size. However, even if the insoles were staggered, difficulties still arise with regard to the different shape of the feet, since the toes of different people are quite different in length from the rest of the foot, while the insoles for an average toe length had to be measured. In people with relatively long toes, this then led to the fact that the front boundary line of the insert came to lie too far forward, ie under the toes, whereas in people with short toes, the The front edge of the insert ran exactly over the bale, which inevitably leads to pressure points and thus walking and standing problems.

Die Sohle nach der Erfindung gestattet es nun, hier Abhilfe zu schaffen, in dem die Länge der Sohle an der Fussinnenseite von der Ferse bis zur Begrenzungslinie hinter dem Grosszehenballen nach einem Mass bemessen ist, welches einer Schuhgrösse entspricht, die um mehrere Grössen-Stufen, vorzugsweise mindestens drei Grössen-Stufen, kleiner ist als die Schuhgrösse, welche dem Mass entspricht, nach dem die Länge der Sohle an der Fussaussenseite von der Ferse bis zur Begrenzungslinie im Bereich des Kleinzehenballens bemessen ist. Bei einem derartigen Vorgehen kann eine Sohle zum Beispiel für drei jeweils um eine ganze Grössen-Stufe differierende Schuhgrössen verwendet werden, so dass es im allgemeinen möglich ist, mit einer relativ begrenzten Zahl von Grössen, beispielsweise je dreien für Herren und Damen, auszukommen. Ein derartiges Vorgehen gestattet die Sohle nach der Erfindung deswegen, weil ja nur gewährleistet sein muss, dass die vordere Begrenzungslinie an der Fussinnenseite hinter deim Grosszehenballen verläuft, während sie im Bereich der Fussaussenseite auf jeden Fall den Kleinzehenballen erfasst, durchaus aber auch bis an das vordere Ende der kleinen Zehe reichen kann. Es wäre sogar denkbar, bei bestimmten Füssen oder Schuhen, wo die Sohle im Kleinzehenbereich zu weit nach vorne reicht, das vordere Ende der Sohle einfach abzuschneiden, was keinesfalls Probleme verursachen kann, da ja die kleine Zehe dann völlig auf der Sohle aufliegt und somit eine eventuell durch das Abschneiden entstehende Kante nicht zu Druckstellen führen kann. Neben dem Effekt, dass wenige Sohlengrössen genügen, um für sämtliche posentiellen Träger passende Sohlen zu Verfügung zu haben, ergibt sich bei der vorerwähnten Ausgestaltung der Sohle auch noch der Vorzug, dass eine Anpassung an unterschiedliche Zehenlängen ohne Schwierigkeiten möglich ist. Dabei tritt dieses Problem ja eigentlichnur bei solchen Trägern auf, deren Fussgrösse im Grenzbereich zwischen zwei Sohlengrössen liegt. Bei Trägern mit langen Zehen wird man dann die kleinere Sohle, bei Personen mit kurzen Zehen die jeweils grössere Sohle verwenden.The sole according to the invention now makes it possible to remedy this situation by measuring the length of the sole on the inside of the foot from the heel to the boundary line behind the ball of the big toe according to a measure which corresponds to a shoe size which is increased by several size levels, preferably at least three size levels, smaller than the shoe size, which corresponds to the dimension by which the length of the sole on the outside of the foot is measured from the heel to the boundary line in the area of the small toe ball. In such an approach, a sole can be used, for example, for three shoe sizes, each differing by an entire size level, so that it is generally possible to manage with a relatively limited number of sizes, for example three for men and women. The sole according to the invention allows such a procedure because it only has to be ensured that the front boundary line on the inside of the foot runs behind the big toe ball, while in the area of the outside of the foot it definitely covers the small toe ball, but definitely also to the front End of the little toe can reach. It would even be conceivable to simply cut off the front end of the sole on certain feet or shoes where the sole extends too far forward in the small toe area, which in no way can cause problems, since the small toe then lies completely on the sole and therefore one any edge that may result from cutting cannot lead to pressure marks. In addition to the effect that a few sole sizes are sufficient to have suitable soles available for all potential wearers, there is also the advantage in the aforementioned embodiment of the sole that adaptation to different toe lengths is possible without difficulty. This problem actually only occurs with straps whose foot size is in the border area between two sole sizes. Those with long toes will use the smaller sole, those with short toes will use the larger sole.

Zur Erreichung des vorerwähnten Zieles hat es sich als zweckmässig erwiesen, wenn die Länge der Sohle an der Fussinnenseite etwa 70% der Länge an der Fussaussenseite beträgt. In diesem Fall erfasst eine Sohlengrösse drei und mehr Grössen-Stufen, ist trotzdem aber in der Lage, die ihr zugedachte Aufgabe ohne weiteres zu erfüllen.In order to achieve the aforementioned goal, it has proven to be expedient if the length of the sole on the inside of the foot is approximately 70% of the length on the outside of the foot. In this case, a sole size covers three or more size levels, but is still able to easily perform the task intended for it.

Wenn mann bestrebt ist, eine Sohlengrösse für unterschiedliche Fusslängen zu verwenden, tritt natürlich aus das Problem auf, dass längere Füsse im allgemeinen auch breiter sind, so dass auch eine Anpassung an unterschiedlich Fussbreiten möglich sein müss. Dies wird nach der Erfindung in einfacher Weise dadurch erreicht, dass entlang der Außen- und Innenkanten und gegebenenfalls die Ferse umgreifend ein gegenüber der restlichen Fläche der Sohle relativ leicht hochbiegbarer Randstreifen vorgesehen ist, wobei dieser Randstreifen zweckmässig von einer etwa parallel zur Sohlenkante verlaufenden Schwächungslinie gebildet ist. Bei einer Ausbildung mit dem relativ flexiblen Randbereich sollte sich die Sohle entlang ihrer Kante einwandbrei an den Schaft bzw. die Sohle des Schuhes anlagen, was dadurch erreicht werden kann, dass die Sohle zumindest zu ihren Seitenkanten und zur Ferste zu in einem schmalen Randbereich gleichmässig verdünnt ist.If one strives to use a sole size for different foot lengths, the problem naturally arises that longer feet are generally also wider, so that an adaptation to different foot widths must also be possible. This is achieved in a simple manner according to the invention in that along the outer and inner edges and possibly the heel, an edge strip which is relatively easily bendable relative to the remaining surface of the sole is provided, this edge strip expediently being formed by a weakening line running approximately parallel to the edge of the sole is. In the case of a design with the relatively flexible edge area, the sole should rest perfectly along its edge on the shaft or sole of the shoe, which can be achieved by the sole being thinned evenly in a narrow edge area at least to its side edges and to the distance is.

Die Sohle nach der Erfindung kann verständlicherweise aus unterschiedlichen Materialien mit entsprechenden federelastischen Eigenschaften hergestellt werden, wobei allerdings eine Herstellung aus den bisher üblichen Brandsohlen-Materialien auf Pappe-Basis wegen der erforderlichen Flexibilität ausscheidet.The sole according to the invention can, of course, be made from different materials with corresponding resilient properties, although production from the cardboard-based insole materials which have hitherto been customary is ruled out because of the required flexibility.

Besonders günstig ist es jedoch, wenn die Sohle aus einem federelastisch biegbaren Kuntstoff, vorzugsweise Polypropylen, besteht, da sie dann unabhängig von ihrer Formgestaltung leicht im Wege des Spritzgiessens hergestellt werden kann und zudem ausreichende mechanische Festigkeit besitzt.However, it is particularly favorable if the sole consists of a resiliently bendable plastic, preferably polypropylene, since it can then be easily produced by injection molding regardless of its shape and also has sufficient mechanical strength.

Die Trageeigenschaften der Sohle lassen sich weiter dadurch verbessern, dass ihre Oberseite grobkörnig aufgerauht ist, so dass, vor allem bei Herstellung aus Kunststoff, sich ein Luftpolster bildet und ausserdem die Fussohle unter Umständen während des Laufens massageartig bewegt wird.The wearing properties of the sole can be further improved by roughening the upper surface so that, especially when made from plastic, an air cushion is formed and the sole of the foot may also be massaged during walking.

Grundsätzlich könnte die Sohle nach der Erfindung ohne besondere Massnahmen als Einlegesohle oder Brandsohle verwendet werden. Günstig ist es jedoch, wenn sie zumindest oberseitig mit einer weichen Decklage, vorzugsweise aus Leder, überzogen ist, die allseits etwas über die Sohle aus federelastischem Material übersteht. Die Anbringung einer Decklage ist vor allem bei Herstellung der Sohle aus Kunststoff fussklimatsch von Vorteil, da die Atmungsfähigkeit des Fusses nicht beeinträchtigt wird. Ein gewisser Überstand dieser Decklage hat den Vorzug, dass im Bereich der Kanten der Sohle keine Druck- oder Scheuerstellen entstehen können. Auch die Unterseite der Sohle könnte natürlich überzogen sein. Im allgemeinen genügt es jedoch bei Verwendung als Einlegesohle, wenn die Unterseite zur Erzielung eines guten Aussehens insgesamt leicht angerauht ist und ausserdem ein in sich gefärbter Kunststoff verwendet wird.In principle, the sole according to the invention could be used as an insole or insole without special measures. However, it is favorable if it is covered at least on the upper side with a soft cover layer, preferably made of leather, which on all sides protrudes somewhat beyond the sole made of resilient material. The application of a top layer is particularly advantageous when the sole is made of plastic foot climate, since the breathability of the foot is not impaired. A certain overhang of this top layer has the advantage that no pressure or chafing points can occur in the area of the edges of the sole. The underside of the sole could of course also be covered. In general, however, when used as an insole, it is sufficient if the underside is slightly roughened overall to achieve a good appearance and, in addition, a self-colored plastic is used.

Ein Mangel der bekannten Einlegesohlen besteht darin, dass diese im Schuh gerne verrutschen. Dies hat man bisher dadurch zu verhindern versucht, dass die Einlegesohlen unterseitig mit selbstklebenden Bereichen versehen wurden. Ein derartiges Vorgehen hat jedoch den Mangel, dass ein Auswechseln der Einlegesohlen nur mit Schwierigkeiten möglich ist und insbesondere die Sohlen jeweils nur in einem Schuh verwendet werden können. Demgegenüber wird nun nach der Erfindung vorgeschlagen, dass die Sohle an der Unterseite wenigstens bereichsweise scharfkantige, ein Verschieben der Sohle bei Benutzung verhindernde, Vorsprünge aufweist, die bei Herstellung der Sohle aus Kunststoff zweckmässig angeformt sein können. Ein derartiges Vorgehen hat den Vorzug, dass die Sohle im Schuh sicher liegt, trotzdem jedoch ohne Schwierigkeiten zum Auswechseln oder zur Verwendung in einem anderen Schuh entnommen werden kann.A shortcoming of the known insoles is that they tend to slip in the shoe. So far, attempts have been made to prevent this by providing self-adhesive areas on the underside of the insoles. However, such a procedure has the deficiency that the insoles can only be replaced with difficulty and in particular the soles can only be used in one shoe at a time. In contrast, it is now proposed according to the invention that the sole has, at least in some areas, sharp-edged projections on the underside which prevent the sole from shifting during use, which protrusions during manufacture of the sole Plastic can be molded appropriately. Such a procedure has the advantage that the sole lies securely in the shoe, but can nevertheless be removed without difficulty for replacement or for use in another shoe.

Es wäre zwar möglich, die Vorsprünge im wesentlichen an der gesamten Unterseite anzubringen, wodurch jedoch deren Eindringtiefe, d.h. der Griff, vermindert werden könnte. Aus diesem Grunde wird vorgeschlagen, dass die Vorsprünge jeweils nur in einem Streifen zwischen Fersenbereich und Gelenk an der Fussinnnenseite und in einem Streifen zwischen Gelenk und Kleinzehenballen an der Fussaussenseite angeordnet sind, wobei der Streifen an der Fussaussenseite ein gewisses Mass vor der vorderen Begrenzungslinie, beispielsweise ca. 15 mm, enden sollte.While it would be possible to attach the protrusions substantially to the entire underside, this would increase their depth of penetration, i.e. the grip that could be diminished. For this reason, it is proposed that the projections are arranged only in a strip between the heel area and the joint on the inside of the foot and in a strip between the joint and small ball of the toe on the outside of the foot, the strip on the outside of the foot a certain measure in front of the front boundary line, for example approx. 15 mm, should end.

Die Gestaltung der Vorsprünge kann verschiedenartig sein. Beispielsweise wäre es möglich, die Vorsprünge sägezahnartig auszubilden, wobei dann die steileren Zahnflanken zur vorderen Begrenzungslinie der Sohle zu weisen müssten. Eine andere Möglichkeit bestünde darin, dass die Vorsprünge von Kegeln mit einem Spitzenwinkel von weniger als 90°, vorzugsweise weniger als 60°, gebildet sind.The design of the projections can be of various types. For example, it would be possible to form the projections in a sawtooth fashion, in which case the steeper tooth flanks would have to point to the front boundary line of the sole. Another possibility would be that the projections are formed by cones with an apex angle of less than 90 °, preferably less than 60 °.

Nachstehend wird ein bevorzugtes Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert.A preferred exemplary embodiment of the invention is explained in more detail below with reference to the drawing.

In der Zeichnung stellen dar:

  • Figur 1 eine Draufsicht auf eine Sohle nach der Erfindung für einen rechten Fuss,
  • Figur 2 eine Unteransicht zu Figur 1,
  • Figur 3 einen Schnitt durch die Sohle nach Linie 111-111 in Figur 1 und
  • Figuren 4 und 5 Schnitt-Seitenansichten zu Figur 2 in Richtung der Pfeile IV und V in Figur 2 gesehen.
In the drawing:
  • FIG. 1 shows a top view of a sole according to the invention for a right foot,
  • FIG. 2 shows a bottom view of FIG. 1,
  • 3 shows a section through the sole according to line 111-111 in Figure 1 and
  • Figures 4 and 5 sectional side views of Figure 2 seen in the direction of arrows IV and V in Figure 2.

Bei der in der Zeichnung dargestellten Sohle handelt es sich um eine Sohle für einen rechten Fuss, die vorzugsweise als Einlegesohle Verwendung findet, in welchem Falle eine strichpunktiert angedeutet Decklage 1 aus vorzugsweise Leder vorzusehen wäre, die die Oberseite (Figur 1) der Sohle 2 allseits etwas überragend abdeckt.The sole shown in the drawing is a sole for a right foot, which is preferably used as an insole, in which case a cover layer 1, preferably indicated by dash-dotted lines, made of leather should be provided, which covers the upper side (FIG. 1) of the sole 2 on all sides covers something outstanding.

Die Sohle 2 des gezeigten Ausführungsbeispieles ist aus Kuntstoff im Wege des Spritzgiessens, vorzugsweise aus Polypropylen, hergestellt, was den Vorteil hat, dass die eigentliche Sohle 2 einschliesslich sämtlicher spezieller Formelemente in einem Arbeitsgang erzeugt werden kann. Ausserdem hat dieser Kunststoff die für die angestrebte Wirkung der Sohle erforderlichen federelastischen Eigenschaften, d.h. die Sohle ist bei entsprechender Dicke zwar noch ausreichend biegbar. Es wird jedoch die gewünschte Unterstützung erreicht.The sole 2 of the exemplary embodiment shown is made of plastic by injection molding, preferably of polypropylene, which has the advantage that the actual sole 2, including all special shaped elements, can be produced in one operation. In addition, this plastic has the spring-elastic properties required for the desired effect of the sole, i.e. the sole is still sufficiently flexible with the appropriate thickness. However, the desired support is achieved.

An der Fussinnenseite, d.h. etwa bei 3, ist die Sohle 2 in an sich bekannter Weise nach oben zur Bildung einer Unterstützung für das Fussgewölbe bzw. Gelenk vorgewölbt. Ausserdem ist die Sohle, mit Ausnahme des vorderen Bereiches 4, d.h. des Bereiches etwa von einer gedachten, durch die Punkte 5 und 6 (in Figur 1) gehenden Linie, entsprechend der Fussform leicht konkav gewölbt, wie dies Figur 3 deutlich erkennen lässt. Diese konkave Ausbildung ist allerdings durch eine Vorwölbung 7 nahe der Linie 5-6 unterbrochen, welche als Metatarsalstütze dient.On the inside of the foot, i.e. 3, the sole 2 is arched upwards in a manner known per se to form a support for the arch of the foot or joint. In addition, the sole, with the exception of the front area 4, i.e. of the area, for example from an imaginary line going through points 5 and 6 (in FIG. 1), slightly concave in accordance with the shape of the foot, as can be clearly seen in FIG. However, this concave formation is interrupted by a bulge 7 near the line 5-6, which serves as a metatarsal support.

Diese Vorwöldung 7 kann lediglich durch entsprechende Verformung der Sohle 2 gebildet sein. Beim dargestellten Ausführungsbeispiel ist die Vorwölbung 7 jedoch durch entsprechende Verdickung der Sohle 2, die im übrigen weitegehend in etwa geleiche Dicke hat, gebildet. Die Dicke der Sohle kann beispielsweise in dem Bereich vor der Linie 5-6 ca. 1,5 mm betragen, während sie in dem Bereich der Füßinnenseite 3, wo das Fussgelenk unterstützt werden soll, ca. 3 mm dick sein kann. Zwischen diesen Werten liegt die Dicke der Sohle praktisch über ihre gesamte Fläche, wobei selbstverständlich zum Rand zu in an sich bekannter Weise eine Verdünnung erfolgt, um das Entstehen scharfer Kanten zur vermeiden.This Vorwöldung 7 can only be formed by appropriate deformation of the sole 2. In the illustrated embodiment, however, the bulge 7 is formed by a corresponding thickening of the sole 2, which for the rest is largely of approximately the same thickness. The thickness of the sole can, for example, be approximately 1.5 mm in the area in front of the line 5-6, while it can be approximately 3 mm thick in the area of the inside of the foot 3 where the ankle is to be supported. The thickness of the sole lies practically over its entire surface between these values, with a thinning to the edge in a manner known per se, of course, in order to avoid the formation of sharp edges.

Um ein sauberes Anliegen der Seitenkanten 8,9 und auch der Kante 10 im Bereich der Ferse an dem Schuh, d.h. entweder das Oberleder oder die Sohle, zu ermöglichen, ist zum einen, wie Figur 3 gut erkennen lässt, die Sohle 2 in einem Randstreifen 11, der entlang der Seitenkanten 8, 9 und um die Ferse verläuft, zu den Kanten 8, 9, 10 zu verjüngt. Darüberhinaus ist an der Unterseite der Sohle eine Rille 12 vorgesehen, die eine Schwächungslinie bildet, wodurch erreicht wird, dass der Randstreifen 11 1 ohne grössere Schiwerigkeiten aus der Ebene der Sohle 2 nach oben oder auch nach unten zur Anpassung an die Form des Schuhes gebogen werden kann.In order for the side edges 8, 9 and also the edge 10 in the area of the heel to fit snugly against the shoe, i.e. To enable either the upper leather or the sole is, on the one hand, as can be clearly seen in FIG. 3, the sole 2 in an edge strip 11, which runs along the side edges 8, 9 and around the heel, to the edges 8, 9, 10 too rejuvenated. In addition, a groove 12 is provided on the underside of the sole, which forms a line of weakness, as a result of which the edge strip 11 1 is bent upward or downward from the level of the sole 2 without major difficulties to adapt to the shape of the shoe can.

Die gezeigte Sohle umfasst weiterhin im Fersenbereich 13 eine zur Aufnahme des Fersenbeines dienende Vertiefung 14, wobei die Gestaltung derart ist, dass eine das Fersenbein beim Auftritt vorne unterstützende und abhebende, in der Zeichnung nicht sichtbare Vorwölbung gebildet ist, wodurch beim Auftritt das Fussgelenk aktiviert wird. Die Ausparung 15 gestattet gegebenenfalls ein Durchkleben, wobei der Rand der Aussparung 15 keine scharfe Kante bilden darf.The sole shown further comprises in the heel area 13 a depression 14 which serves to receive the heel bone, the design being such that a protrusion which supports the heel bone at the front and is raised and is not visible in the drawing is formed, as a result of which the ankle is activated when the step occurs . The recess 15 optionally allows sticking through, the edge of the recess 15 must not form a sharp edge.

In Figur 1 ist weiter bei 16 an mehreren Stellen angedeutet, dass die Oberseite 17 der Sohle 2 grobkörnig aufgerauht ist, d.h. in einer Tiefe von etwa 0,2 bis 0,3 mm und mit einer Körnung über die Fläche von mehreren Millimetern. Diese Aufrauhung bietet vor allem bei Vorhandensein einer Decklage 1 aus Leder eine günstige Auftrittsfläche für den Fuss und kann ausserdem zur Erhöhung der Steifigkeit der Sohle 2 bei entsprechender Ausbildung beitragen.In Figure 1 it is further indicated at 16 in several places that the upper side 17 of the sole 2 is roughened coarsely, i.e. at a depth of about 0.2 to 0.3 mm and with a grain size of several millimeters. This roughening offers a favorable tread surface for the foot, particularly in the presence of a leather cover layer 1, and can also contribute to increasing the rigidity of the sole 2 with appropriate training.

An der Unterseite 18 sind in zwei streifenförmigen Bereichen 19 bzw. 20 (Figur 2) scharfkantige Vorsprünge vorgesehen, wobei die Vorsprünge im Bereich 19 in Figur 4, die des Bereiches 20 in Figur 5 in vergrössertem Massstab gezeigt sind.On the underside 18 are sharp-edged areas in two strip-shaped areas 19 and 20 (Figure 2) Protrusions are provided, the protrusions in the area 19 in FIG. 4 and those of the area 20 in FIG. 5 on an enlarged scale.

Die Vorsprünge 21 des Bereiches 19 an der Fussaussenseite, die sich etwa vom Gelenkbereich bis in den Bereich des Kleinzehenballens erstrecken, sind etwa sägezahnförmig ausgebildet und weisen eine dachflächenartige scharfe Kante 22 auf. Ihre Orientierung ist so, dass die steilere Flanke 23 nach vorne, d.h. zur vorderen Begrenzungslinie 24 der Sohle weist, so dass ein Vorrutschen der Sohle bei Benutzung verhindert wird.The projections 21 of the area 19 on the outside of the foot, which extend approximately from the joint area to the area of the small toe ball, are approximately sawtooth-shaped and have a roof-like sharp edge 22. Their orientation is such that the steeper flank 23 is forward, i.e. to the front boundary line 24 of the sole, so that the sole is prevented from slipping during use.

Bei der Ausführungsform gemäss Figur 5, die bei dem gezeigten Ausführungsbeispiel in dem streifenförmigen Bereich 20 zwischen dem Gelenk und dem Fersenbereich 13 vorgesehen ist, haben die Vorsprünge 25 Kegelform. Ihr Öffnungswinkel im Bereich der Spitze 26 beträgt vorzugsweise weniger als 60°.In the embodiment according to FIG. 5, which in the exemplary embodiment shown is provided in the strip-shaped region 20 between the joint and the heel region 13, the projections 25 have a conical shape. Your opening angle in the region of the tip 26 is preferably less than 60 °.

Die für das Tragen und die Wirkung der Sohle nach der Erfindung wesentlichsten Merkmale liegen in der speziellen Formgebung, die nachstehend näher erläutert werden soll.The most essential features for wearing and the effect of the sole according to the invention lie in the special shape, which will be explained in more detail below.

Bei bisher bekannten Sohlen, insbesondere Einlegesohlen, verlief die vordere Begrenzung etwa entlang der Linie 5-6 in Figur 1, d.h. hinter dem Grosszehenballen 27 und dem Kleinzeihenballen 28. Demgegenüber ist bei der Sohle nach der Erfindung die vordere Begrenzungslinie 24 nun so schräg zur Sohlen-Längsachse gelegt, dass im Bereich der Fussinnenseite die Sohle hinter dem Grosszehenballen 27 endet, während an der Fussaussenseite die Sohle 2 bis zu dem Punkt 29 reicht, der weit vor dem Kleinzehenballen 28 gelegen ist. Zwischen den Punkten 5 und 29 verläuft die vordere Begrenzungslinie 24 etwa S-förmig, wobei auf jeden Fall dafür Sorge getragen ist, dass der Grosszehenballen 27 vollständig vor der Sohle 2 liegt, während der Kleinzehenballen 28 und die kleine Zehe, eventuell auch die vierte Zehe, auf dem vorderen Bereich 4 der Sohle 2 vor der Linie 5-6 aufliegen. Bei dem Punkt 5 handelt es sich dabei um einen gedachten Punkt am Schnittpunkt der vorderen Begrenzungslinie 24 und der inneren Seitenkante 8 der Sohle 2. Tatsächlich ist die den Punkt 5 bildende Ecke der Sohle bei 30 abgeschrägt bzw. abgerundet, so dass keine Beschädigung des Schuhes zu befürchten ist. Die Decklage 1 ragt dagegen entsprechend weit vor und bildet eine Ecke 31, die jedoch, da ja die Decklage 1 aus weichem Material besteht, nicht zu Beschädigungen führen kann.With previously known soles, in particular insoles, the front boundary ran approximately along the line 5-6 in FIG. behind the big toe ball 27 and the small toe ball 28. In contrast, in the sole according to the invention the front boundary line 24 is now so inclined to the longitudinal axis of the sole that in the area of the inside of the foot the sole ends behind the big toe ball 27, while on the outside of the foot the sole 2 extends to the point 29, which is located far in front of the small toe ball 28. The front boundary line 24 runs approximately S-shaped between points 5 and 29, care being taken in any case that the big toe ball 27 lies completely in front of the sole 2, while the small toe ball 28 and the small toe, possibly also the fourth toe , lie on the front area 4 of the sole 2 in front of the line 5-6. The point 5 is an imaginary point at the intersection of the front boundary line 24 and the inner side edge 8 of the sole 2. In fact, the corner of the sole forming the point 5 is chamfered or rounded off at 30, so that the shoe is not damaged is to be feared. The cover layer 1, on the other hand, protrudes correspondingly far and forms a corner 31 which, however, since the cover layer 1 is made of soft material, cannot lead to damage.

Die Sohle 2 ist nun aus einem solchen Material hergestellt, das ausreichende Steifheit besitzt, um zu gewährleisten, dass durch den vorderen Bereich 4, d.h. dem Bereich zwischen der Linie 5-6 und dem Punkt 29 der Kleinzehenballen 28 und vorzugsweise auch die kleine Zehe während der Abrollbewegung des Fusses beim Laufen unterstützt werden, wobei die Unterstützung so stark ist, dass beim Abrollen der Fuss in Richtung auf den Grosszehenballen 27 bzw. die in der Zeichnung nicht dargestellte Grosszehe nach innen verdreht wird. Auf diese Weise ergibt sich eine Laufbewegung, die das Gelenk der Grosszehe kräftig beansprucht, ohne eine Tendenz der Grosszehe hervorzurufen, sich nach innen zu verlagern, so dass die oben erwähnten Fussbeschwerden nicht zu befürchten sind.The sole 2 is now made of such a material that has sufficient rigidity to ensure that through the front area 4, i.e. the area between the line 5-6 and the point 29 of the small toe pads 28 and preferably also the small toe are supported during the rolling movement of the foot while running, the support being so strong that when the foot rolls off in the direction of the big toe pads 27 or the big toe, not shown in the drawing, is turned inwards. In this way there is a running movement which places a heavy load on the joint of the big toe without causing a tendency of the big toe to shift inwards, so that the foot problems mentioned above are not to be feared.

Nachdem die Sohle 2 üblicherweise auch im Bereich der vorderen Begrenzungslinie 24 sich verjüngt, so dass keine Kante entsteht, besteht weitgehende Freiheit bezüglich des Masses, um das der vordere Bereich 4 bis zum Punkt 29 über die gedachte Linie 5-6 vorsteht. Bei der dargestellten Sohle sind nun die Abmessungen so gewählt, dass das Mass zwischen dem Punkt 5 im Bereich der Fussinnenseite und dem Punkt 32 an der Ferse etwa 70% des Masses zwischen dem Punkt 29 an der Spitze der Sohle 2 und dem Punkt 32 an der Ferse beträgt. Eine derartige Bemessung der Sohle bietet den Vorteil, dass ein und dieselbe Sohle für mehrere Fussgrössen, beispielsweise drei ganze Schuhgrössen nach dem englischen oder französischen System, verwendet werden kann. Dabei befindet sich bei relative kleinen Füssen oder verhältnissmässig langen Zehen die vordere Begrenzungslinie 24 verhältnissmässig nahe am Grosszehenballen 27, während bei grösseren Füssen oder kürzeren Zehen der Abstand zwischen dem Grosszehenballen 27 und der vorderen Begrenzungslinie 24 entsprechend grösser ist. In gleicher Weise wird bei grossen Füssen bzw. kurzen Zehen der Kleinzehenballen 28 sich relativ weit vorne im Bereich 4, d.h. nahe dem Punkt 29 befinden, so dass die Kleinzehe nur noch teilweise oder überhaupt nicht auf dem Bereich 4 der Sohle 2 aufliegt, während bei kleinen Füssen bzw. langen Zehen der Kleinzehenballen 28 sich verhältnismässig nahe an der Line 5-6 befinden dürfte. Sollte in einem derartigen Fall der Bereich 4 bzw. der Punkt 29 soweit vorne liegen, dass das Einsetzen der Sohle in den Schuh Schwierigkeiten bereitet, so kann das vordere Ende des Bereiches 4 nahe dem Punkt 29 in einfacher Weise mittels einer Schere oder dergleichen gekürzt werden.Since the sole 2 usually also tapers in the area of the front boundary line 24 so that no edge is formed, there is extensive freedom with regard to the amount by which the front area 4 protrudes to the point 29 over the imaginary line 5-6. In the sole shown, the dimensions are now selected such that the dimension between point 5 in the area of the inside of the foot and point 32 on the heel is approximately 70% of the dimension between point 29 at the tip of the sole 2 and point 32 on the Heel is. Such a dimensioning of the sole offers the advantage that one and the same sole can be used for several foot sizes, for example three whole shoe sizes according to the English or French system. In the case of relatively small feet or relatively long toes, the front boundary line 24 is relatively close to the big toe ball 27, while with larger feet or shorter toes the distance between the big toe ball 27 and the front boundary line 24 is correspondingly larger. In the same way, with large feet or short toes, the small toe pads 28 will move relatively far forward in area 4, i.e. are close to the point 29, so that the small toe only partially or not at all rests on the area 4 of the sole 2, while with small feet or long toes the small toe pads 28 should be relatively close to the line 5-6. If, in such a case, area 4 or point 29 is so far forward that it is difficult to insert the sole into the shoe, the front end of area 4 near point 29 can be shortened in a simple manner using scissors or the like .

Aus der Zeichnung ist weiter ersichtlich, dass die vordere Begrenzungslinie 24 etwa S-förmig ist und an ihrem Anfang bzw. Ende, d.h. etwa bei dem Punkten 5 und 29, nahezu senkrecht auf die Seitenkanten 8 bzw. 9 der Sohle auftritt. Diese S-förmige Gestaltung der vorderen Begrenzungslinie 24 hat den Vorzug, dass es normalerweise nicht zur Bildung von Druckstellen kommen kann, selbst wenn die Begrenzungslinie 24 eine gewisse Kante darstellen sollte.From the drawing it can also be seen that the front boundary line 24 is approximately S-shaped and at its beginning or end, i.e. approximately at points 5 and 29, almost perpendicular to the side edges 8 and 9 of the sole. This S-shaped design of the front boundary line 24 has the advantage that pressure points cannot normally be formed, even if the boundary line 24 should represent a certain edge.

Wie bereits erwähnt, bietet der Umstand, dass eine erhebliche Längendifferen zwischem dem Mass 5-32 an der Fussinnenseite und dem Mass 29-32 an der Fussaussenseite besteht, die Möglichkeit, mit wenigen Sohlengrössen auszukommen. Der Grund hierfürist darin zu sehen, dass dann, wenn die innere Länge 5-32 nur etwa 70% der äusseren Länge von 29-32 beträgt, dies gleichbedeutend damit ist, dass die Länge der Sohle an der Fussinnenseite von der Ferse bis zur Begrenzungslinie 24 hinter dem Grosszehenballen 27 nach einem Mass bemessen ist, welches einer Schuhgrösse entspricht, die um mehre, im dargelegten Falle drei, Grössen-Stufen kleiner ist als die Schuhgrösse, welche dem Mass 29-32 entspricht, nach dem die Länge der Sohle 2 an der Fussaussenseite von der Ferse bis zur Begrenzungslinie 24 im Bereich des Kleinzehenballens 28 bemassen ist. Es benügt daher beispielsweise, drei Sohlengrössen für Herren bzw. Damen vorzusehen, wobei folgende Masse in Frage kommen:As already mentioned, the fact that there is a considerable difference in length between the size 5-32 on the inside of the foot and the size 29-32 on the outside of the foot offers the possibility of using only a few sole sizes. The reason for this is that if the inner length 5-32 is only about 70% of the outer length 29-32, this means that the length of the sole on the inside of the foot from the heel to the boundary line 24 behind the big toe ball 27 is dimensioned to a size that corresponds to a shoe size that is several, in the case described three, size steps smaller than that Shoe size, which corresponds to the measure 29-32, according to which the length of the sole 2 on the outside of the foot is dimensioned from the heel to the boundary line 24 in the region of the small toe ball 28. It is therefore sufficient, for example, to provide three sole sizes for men and women, the following dimensions being possible:

Es ist also möglich, mit lediglich drei Damen- und Herren-Sohlengrössen praktisch alle normalerweise auftretenden Schuhgrössen abzudecken, wobei im Übergangsbereich gei Füssen mit längeren Zehen die jeweils kleinere, bei Füssen mit verhältnismässig kurzen Zehen dagegen die jeweils grössere Gruppengrösse verwendet werden sollte.It is therefore possible to cover practically all shoe sizes that normally occur with just three women's and men's sole sizes, whereby the smaller group size should be used in the transition area for feet with longer toes, whereas the larger group size should be used for feet with relatively short toes.

Der Grundgedanke der Erfindung, nämlich der relativ biegesteife Strahl an der Fussaussenseite, kann bei Schuhen nicht nur durch ein besonderes Einbauteil sondern beispielsweise auch durch entsprechende Gestaltung und Ausbildung einer Sohle, z.B. einer Formgummisohle, verwirklicht werden.The basic idea of the invention, namely the relatively rigid beam on the outside of the foot, can not only be achieved with shoes by a special built-in part, but also, for example, by appropriate design and construction of a sole, e.g. a molded rubber sole.
