- the contour 15 'of the correction strip 15 can extend in the region of the instep 33 starting from the bend 42 to the toe area parallel to the foot 31. But it is also possible to choose a different contour, which is based essentially on the inner surface of the existing shoe shell.
- the correction strip 15 has a contour which is narrower than the human foot.
- the metatarsal area is slightly compressed, which causes no pain due to the existing articulated bone structure, but produces a very good support effect from the side and also ensures that the heel 30 is held in place during the exercise of the sport and not forward can slip.
- the toe bales 38 and 39 it is advantageous to provide an excess so as not to cause pressure points on the sensitive bones. Furthermore, it will be advantageous to make an excess in the toe area 40 in order to avoid frostbite. Also, the natural sense of balance is maintained throughout the toe area 40 because the foot receptors are not blocked by the clearance.
- an axis 19 with an angle ⁇ relative to a vertical axis Z may be present (s. Fig. 16 ) to set an individual template.
- Fig. 18 is designed as a standard strips correction strips 15 at neuralgic sites with holes 43.

- the parts 44 are produced by the plastic injection molding process, wherein it has been found that a certain elasticity is particularly advantageous for the shaping process. Accordingly, preferred materials are Group of silicone elastomers and thermoplastic elastomers in a hardness range Shore D between 45 and 65 suitable.
- An advantage of this variant is that you can produce a set of base rails per shoe size and can represent many different feet on a kind of modular system with different plastic parts.
- FIGS. 20 and 21 illustrated method of manufacturing or adaptation of the shoe 11 highlighted.
- a shoe 11 is preferred for adaptation to the individual foot Fig. 15 used, ie, a shoe in which the lower portion 17, substantially below the line 28, consists of a material having a high softening point, for example 150 ° C, whereas for the upper portion of the shell 1 and the cuff. 2 a plastic is used which has a relatively low softening temperature, eg 60 to 80 ° C; It is then easily possible that instead of the correction strip 15 for shaping directly the leg 50 and the foot 6 of the user draws. This is done so that the shoe 11 is heated to a temperature of 60 to 80 ° C, the user according to Fig.
- a film 25 in the form of a bag inverts and this film 25 above the upper edge of the shoe 11 with a suitable attachment means, such as an adhesive tape 51, attaches to the calf of the leg 50 of the user.
- the foil bag 25 is at a suitable location, e.g. in the front sleeve area, provided with a valve 22 and a hose 23 through which vacuum is applied along the arrow P, i. Air can be sucked to evacuate the interior of the film bag 25.

Abstract
Description
Die Erfindung betrifft allgemein die Herstellung von Schuhen aus hartem Kunststoff für Sportzwecke, d.h. von Schuhen, die insbesondere eine harte, widerstandsfähige, thermoplastische Kunststoff-Außenschale aufweisen.The invention relates generally to the manufacture of hard plastic footwear for sports purposes, i. of shoes, in particular having a hard, durable, thermoplastic outer shell.
Mehr im Einzelnen betrifft die Erfindung ein Verfahren zur Herstellung eines an den Fuß eines Benützers angepassten Schuhs aus hartem, thermoplastischem Kunststoff für Sportzwecke, wobei ein vorgefertigter Schuh zumindest bereichsweise erwärmt und durch Verformen des erwärmten Bereichs unter Druckanwendung von außen angepasst wird, wonach der Schuh abgekühlt wird.More particularly, the invention relates to a method of making a hard-plastic thermoplastic shoe adapted to a user's foot, wherein a prefabricated shoe is at least partially heated and adjusted by deforming the heated region from the outside under pressure, after which the shoe cools becomes.
Weiters bezieht sich die Erfindung auf einen Leisten zur Durchführung des Verfahrens sowie auch auf ein Verfahren zur Herstellung eines derartigen leistens.Furthermore, the invention relates to a strip for carrying out the method and also to a method for producing such a thing.
Kunststoff-Schuhe für Sportzwecke, wie etwa Skischuhe für den alpinen Skilauf oder Langlauf-Skischuhe, werden in der Regel aus Kunststoff durch Spritzgießen hergestellt. Eine Fertigstellung von Langlauf-Skischuhen durch Anspritzen einer Schuhsohle, die Bindungsteile enthält, an bereits vorgefertigte Schuhteile ist aus der
Aus
Bei der Herstellung von Schuhen aus thermoplastischem Kunststoff insbesondere durch Spritzgießen ist es allgemein üblich, einen Schuh für eine bestimmte Schuhgröße zu erzeugen. Ein derartiger allgemein geformter Schuh passt jedoch häufig nicht zu den individuellen Füßen von Benützern, da Füße beispielsweise im Zehenballenbereich verschieden breit sind oder auch einen verschieden hohen Rist haben und/oder andere Unterschiede aufweisen können. Es besteht daher grundsätzlich die Möglichkeit, die Schuhe jeweils nach Maß, entsprechend der jeweiligen Fußform (vgl. die oben genannte
In der

Die
Es ist nun Aufgabe der Erfindung, in einfacher und zuverlässiger Weise eine Herstellung eines angepassten Schuhs, d.h. eine individuelle Anpassung eines Schuhs an einen Fuß eines Benützers, zu ermöglichen, wobei sich insbesondere eine Evakuieröffnung im Schuh erübrigen kann und nichtsdestoweniger eine relativ hohe Druckdifferenz zwischen Schuhaußenseite und Schuhinnenseite für die Verformung des Schuhs zwecks Anpassung an einen Fuß erzielen lässt. Es soll auf diese Weise die Verwendung eines einzigen durchschnittlichen Werkzeugleistens bei der Herstellung des vorgefertigten Schuhs möglich sein, d.h. es sollen sich auch bei einer gegebenen Schuhgröße verschiedene allgemeine Leisten nach Möglichkeit erübrigen können.It is an object of the invention to provide in a simple and reliable manner a manufacture of a fitted shoe, i. an individual adaptation of a shoe to a foot of a user to allow, in particular, an evacuation opening in the shoe is unnecessary and nevertheless can achieve a relatively high pressure difference between the shoe outside and shoe inside for the deformation of the shoe to adapt to a foot. It should thus be possible to use a single average tooling in the manufacture of the prefabricated shoe, i. It should also be possible for a given shoe size different general bars as far as possible.
Zur Lösung der gestellten Aufgabe zeichnet sich das Verfahren der eingangs angegebenen Art gemäß einem ersten Aspekt der Erfindung dadurch aus, dass in den vorgefertigten Schuh ein vom Fuß abgenommener Korrekturleisten aus hartem Material eingebracht wird, und dass der erwärmte Schuh durch die Druckanwendung an den Korrekturleisten angepresst wird.To achieve the object, the method of the type specified according to a first aspect of the invention is characterized in that in the prefabricated shoe removed from the foot correction strips made of hard material is introduced, and that the heated shoe pressed by the pressure application to the correction strips becomes.
Bei Verwendung eines derartigen Korrekturleistens, der individuell an den Fuß des jeweiligen Benutzers angepasst ist, kann eine vergleichsweise gute Abdichtung sowie auch die Anwendung einer vergleichsweise höheren Temperatur für die Warmverformung vorgesehen werden, so dass die gewünschte Anpassung des Schuhs bei äußerer Druckaufbringung in einfacher und effizienter Weise ermöglicht wird.When using such a correction strip, which is individually adapted to the foot of each user, a comparatively good seal and the application of a relatively higher temperature for the hot deformation can be provided, so that the desired adaptation of the shoe with external pressure application in a simpler and more efficient Way is possible.
Bei Skischuhen (für den Alpin-Skilauf ebenso wie für den Langlauf) hat der Sohlenbereich des Schuhs eine vorgegebene Funktion hinsichtlich Zusammenwirken mit Bindungsteilen am Ski, so dass beim Anpassungs-Verformen des Schuhs der Sohlenbereich nach Möglichkeit nicht mehr verformt werden sollte. Insofern ist es daher gemäß der vorliegenden Erfindung weiter günstig, wenn für den Sohlenbereich des Schuhs ein Material mit höherer Erweichungstemperatur, z.B. 170°C, als für den restlichen Bereich des Schuhs, z.B. einer Schale und einer Manschette, verwendet wird.In the case of ski boots (for alpine skiing as well as for cross-country skiing), the sole area of the shoe has a predetermined function with regard to interaction with binding parts on the ski so that the sole area should not be deformed as far as possible when adapting the shoe. In this respect, it is therefore according to the present invention further favorable if, for the sole region of the shoe, a material with a higher softening temperature, eg 170 ° C, than for the rest of the shoe, such as a shell and a cuff is used.
Um beim Korrekturleisten eine genaue individuelle Anpassung an den Fuß zu ermöglichen, ist es auch von Vorteil, wenn ein Grund-Korrekturleisten hergestellt wird, welcher an den neuralgischen Stellen mit Löchern versehen wird, in die elastische Formteile eingesetzt werden.In order to allow a precise customization of the foot in the correction strips, it is also advantageous if a basic correction strips is made, which is provided at the neuralgic sites with holes in the elastic moldings are used.
Um im Fall eines Sportschuhs, insbesondere Skischuhs, bei der Sportausübung vom Bein über den Schuh entsprechende Kräfte übertragen zu können, ist es zweckmäßig, an bestimmten Fußstellen eine möglichst enge Passung vorzusehen, wogegen an anderen Stellen ein eher komfortabler Sitz des Fußes im Schuh erwünscht ist. In diesem Zusammenhang hat es sich daher als vorteilhaft erwiesen, wenn ein Korrekturleisten eingesetzt wird, der zwischen dem Kahnbein (Os naviculare) an der Fußinnenseite bzw. dem Basishöcker an der Fußaußenseite einerseits und dem Bereich des Großzehenballens bzw. dem Bereich des Kleinzehenballens andererseits schmäler als der abgemessene menschliche Fuß ist. Andererseits ist es hier günstig, wenn im Bereich der Zehenballen ein Übermaß vorgesehen wird, und/oder wenn im Zehenbereich ein freier Raum vorhanden ist. Für die Anwendung als Skischuh für den Alpin-Skilauf ist es auch vorteilhaft, wenn der Korrekturleisten zur Erzielung einer Vorlage eine Achse unter einem Winkel gegenüber einer lotrechten Achse aufweist.In order to be able to transmit appropriate forces in the exercise of the leg over the shoe in the case of a sports shoe, especially ski boot, it is expedient to provide a tight fit as possible at certain footings, whereas at other locations a more comfortable fit of the foot in the shoe is desired , In this context, it has therefore proven to be advantageous if a correction strips is used, the narrower between the navicular (Os naviculare) on the inside of the foot or the base bump on the foot outside on the one hand and the area of the big toe ball or the area of the small toe bale the measured human foot is. On the other hand, it is favorable here if oversize is provided in the area of the toe bale and / or if there is free space in the toe area. For use as a ski boot for alpine skiing, it is also advantageous if the correction strips to achieve a template has an axis at an angle to a vertical axis.
Der vorerwähnte Grund-Korrekturleisten kann insbesondere auch zur Vereinfachung des Verfahrens pro Schuhgröße hergestellt werden, es können aber auch einige wenige Grund-Korrekturleisten für jede Schuhgröße erzeugt werden; im Anschluss an die Erzeugung des Grund-Korrekturleistens wird die erwähnte individuelle Anpassung durch Einsetzen der elastischen Formteile vorgenommen.The above-mentioned basic correction strips can in particular also be made to simplify the method per shoe size, but it is also possible to produce a few basic correction strips for each shoe size; following the generation of the basic correction strip, the mentioned individual adaptation is carried out by inserting the elastic molded parts.
Für die Erzeugung des Korrekturleistens hat es sich weiters als besonders vorteilhaft erwiesen, wenn die Form des Korrekturleistens durch Abtasten des Fußes des jeweiligen Benützers mittels einer Digitalisierkamera und Verarbeiten der gewonnenen Daten in einem Rechner gewonnen wird.For the generation of the correction strip, it has also proved to be particularly advantageous if the shape of the correction strip is obtained by scanning the foot of the respective user by means of a digitizing camera and processing the data obtained in a computer.
Für eine einfache Druckaufbringung bzw. Erzeugung eines Differenzdrucks zwischen Außenseite und Innenraum des Schuhs hat es sich auch als günstig gezeigt, wenn über den gesamten vorgefertigten Schuh und den Korrekturleisten eine Folie gestülpt und verschlossen wird, der Innenraum der Folie evakuiert und dadurch der Schuh an den Korrekturleisten angepresst wird, und nach einer Verweilzeit zur Erstarrung des Kunststoffs der Schuh entnommen wird.For a simple pressure application or generation of a differential pressure between the outside and the interior of the shoe, it has also been shown to be favorable, if over the entire prefabricated Shoe and the correction strips a film is slipped and closed, the interior of the film is evacuated and thereby the shoe is pressed against the correction strips, and after a residence time for solidification of the plastic shoe is removed.
In vergleichbarer Weise sieht die Erfindung ein Verfahren zur Herstellung eines an den Fuß eines Benützers angepassten Schuhs aus hartem, thermoplastischem Kunststoff für Sportzwecke vor, wobei ein vorgefertigter, am Fuß befindlicher Schuh zumindest bereichsweise erwärmt und durch Verformen des erwärmten Bereichs unter Druckausübung angepasst wird, wonach der Schuh abgekühlt wird; dieses Verfahren zeichnet sich erfindungsgemäß dadurch aus, dass ähnlich wie beim vorerwähnten Verfahren über den gesamten vorgefertigten Schuh eine Folie gestülpt wird, diese im Wadenbereich verschlossen wird, der Innenraum der Folie evakuiert wird und dadurch der Schuh an den Fuß gepresst wird, wonach, nach einer Verweilzeit zur Erstarrung des Kunststoffs, der Schuh entnommen wird.Similarly, the invention provides a method of making a hard-plastic thermoplastic shoe adapted to the foot of a user for sports purposes wherein a prefabricated foot-worn shoe is at least partially heated and adjusted by deforming the heated area under pressure, followed by the shoe is cooled; This method is inventively characterized in that similar to the above-mentioned method over the entire prefabricated shoe, a film is placed, this is closed in the calf area, the interior of the film is evacuated and thereby the shoe is pressed against the foot, which, after a Dwell time for solidification of the plastic, the shoe is removed.
Für die Durchführung des erfindungsgemäßen Verfahrens sieht die Erfindung weiters einen Leisten vor, der als vom Fuß des Benützers abgenommener Korrekturleisten aus hartem Material gebildet ist. Bei diesem Leisten ist es von besonderem Vorteil, wenn der Abstand zwischen dem Kahnbein (Os naviculare) an der Fußinnenseite bzw. dem Basishöcker an der Fußaußenseite und dem Bereich des Großzehenballens bzw. dem Bereich des Kleinzehenballens schmäler als der abgemessene menschliche Fuß ist. Weiters ist es günstig, wenn er als Grund-Korrekturleisten für eine Schuhgröße vorgesehen und an den neuralgischen Stellen mit Löchern versehen ist, in die elastische Formteile einsetzbar sind. Vorteilhaft ist es auch, wenn im Bereich der Zehenballen ein Übermaß vorhanden ist, und/oder wenn im Zehenbereich ein freier Raum vorhanden ist. Für den alpinen Skilauf ist es weiters zweckmäßig, wenn der Korrekturleisten zur Erzielung einer Vorlage eine Achse aufweist, die um einen Winkel gegenüber einer lotrechten Achse geneigt ist.For carrying out the method according to the invention, the invention further provides a last, which is formed as removed from the foot of the user correction strips of hard material. In this last, it is particularly advantageous if the distance between the scaphoid bone (naviculare bone) on the inside of the foot or the base bump on the outside of the foot and the area of the big toe ball or the area of the toe is narrower than the measured human foot. Furthermore, it is advantageous if it is provided as a basic correction strips for a shoe size and is provided at the neuralgic sites with holes into which elastic molded parts can be used. It is also advantageous if an excess is present in the area of the toe bale, and / or if there is a free space in the toe area. For alpine skiing, it is further expedient if the correction strips to achieve a template has an axis which is inclined at an angle relative to a vertical axis.
Wie erwähnt sieht die Erfindung auch einen Hartschalen-Schuh für die Anwendung im vorliegenden Verfahren bzw. hergestellt nach dem vorliegenden Verfahren vor, wobei eine Unterschale und eine Manschette aus Kunststoff vorgesehen sind und im Einzelnen Unterschale und Manschette aus unterschiedlichen Kunststoffen hergestellt sind. Insbesondere wird ein derartiger Hartschalen-Schuh für ein bzw. nach einem Verfahren wie vorstehend erwähnt vorgesehen, der eine Unterschale und eine Manschette aus thermoplastischem Kunststoff aufweist, wobei mindestens ein Bereich der Unterschale aus einem Kunststoff mit einer höheren Erweichungstemperatur als jener des restlichen Bereichs der Unterschale und der Manschette hergestellt ist.As mentioned, the invention also provides a hard shell shoe for use in the present process or produced according to the present method, wherein a lower shell and a sleeve made of plastic are provided and in particular lower shell and sleeve are made of different plastics. In particular, such a hard shell shoe is provided for a method as mentioned above comprising a lower shell and a thermoplastic sleeve, wherein at least a portion of the lower shell is made of a plastic having a higher softening temperature than that of the remaining portion of the lower shell and the cuff is made.

Innerhalb des aus den Formhälften 8, 8' bestehenden Werkzeugs ist ein sog. Formleisten 9 eingebaut, welcher in bestimmten Bereichen eine andere Kontur aufweist als die beiden Formhälften 8 und 8', wodurch ein Hohlraum gebildet wird, welcher mit flüssigem Kunststoffmaterial aus einer Spritzgießmaschine 10 ausgefüllt wird.

Um eine wirtschaftliche Herstellung von Schuhen, wie aus der Schuhmacherei für einen Maßschuh bekannt ist, zu ermöglichen, wird der Formleisten 9 auf eine durchschnittliche Schuhgröße bzw. Fußform ausgelegt, um die Möglichkeit zu bieten, den Schuh für eine möglichst breite Masse verwenden zu können. Im Hinblick auf die Unterschiede bei den individuellen Fußformen sieht man im Innenschuh 3 verformbare Polster vor, damit einerseits ein Kontakt zur Außenschale sichergestellt ist und andererseits eine gewisse Knautschzone gebildet wird, damit es zu keinen schmerzhaften Druckstellen am Fuß kommt. Dies hat jedoch den Nachteil, dass man relativ weiche Zonen schafft, wobei die Kraftübertragung vom Fuß zum Sportgerät verschlechtert wird.In order to enable an economical production of shoes, as is known from the shoe industry for a custom shoe, the
Es wird daher vorgesehen, eine Kunststoffschale, welche auf einem durchschnittlichen Werkzeugleisten herstellbar ist, an einen individuellen Fuß anzupassen. Durch eine solche nachträgliche individuelle, gute Passform hat der menschliche Fuß bei Ausübung von Sportarten einen guten Kontakt zur Außenschale, wobei Kräfte, die bei der Sportausübung, beispielsweise beim Skilaufen, entstehen, zwischen Fuß- und Sportgerät gut übertragen werden. Für diese Anpassung wird gemäß
