Die Innenschuhe bestehen zu diesem Zweck aus einem besonderen Kunststoffmaterial, das bei einer gewissen Temperatur gute Verformbarkeit besitzt. Diese Temperatur liegt dabei deutlich oberhalb der während des Tragens im Schuh auftretenden Temperaturen. damit eine nachträgliche Verformung unterbunden wird und der Innenschuh dem Fuß einen entsprechenden Halt bietet. Normalerweise wird der Innenschuh zum Zweck des Anpassens an die Fußform zuerst aus der Schale des Schuhs entnommen, über die für eine leichte Verformung notwendige Temperatur erwärmt und danach wieder in die Schale des eingebracht. Der Träger des Schuhs zieht diesen in erwärmtem Zustand an, wobei sich der Innenschuh an die Fußform anpaßt. Der Vorgang zur Anpassung des Innenschuhs an die Fußform ist dabei sehr aufwendig. da der Innenschuh zuerst aus der Schale entnommen. dann zum Beispiel in einem Ofen oder dergleichen erwärmt und dann wieder in die Schale des Schuhs eingebracht werden muß bevor die Anpassung des Innenschuhs an die Fußform erfolgen kann. Dauert das Einbringen des Innenschuhs in die Schale des Schuhs zu lange. kann auch vorkommen daß die Temperatur des Innenschuhs unter die für optimale Verformung notwendige Temperatur sinkt und somit keine ausreichende Anpassung an die Fußform erfolgen kann.It has been liner for a while. especially known for ski boots, which for Adaptation to the shape of the foot to avoid pressure points under the application of heat are deformable. For this purpose, the inner shoes consist of a special one Plastic material that has good ductility at a certain temperature. This The temperature is significantly higher than that which occurs in the shoe during wear Temperatures. so that subsequent deformation is prevented and the inner shoe provides the foot with a suitable grip. Usually the liner is for the purpose of adapting to the shape of the foot first taken from the shell of the shoe, over which for a slight deformation necessary temperature warmed up and then back into the shell of the brought in. The wearer of the shoe pulls it on when heated, whereby the Fits liner to the shape of the foot. The process of adapting the liner to the The shape of the foot is very complex. since the inner shoe is first removed from the shell. then for example heated in an oven or the like and then put back into the bowl of the Shoe must be introduced before the liner is adjusted to the shape of the foot can be done. It takes too long to insert the liner into the shell of the shoe. It can also happen that the temperature of the liner is below that for optimal Deformation necessary temperature drops and thus no adequate adaptation to the Foot shape can be made.

Als Anwendungsbeispiel wird eine Sohle für Sportschuhe erwähnt. Beispiele elektrischer Heizungen in Schuhen nur zum Zueck der Erwärmung des Fußes sind der US 4 782 602 A, EP 084 789 A1, DE 25 49 375 A1 oder der US 2 298 299 A zu entnehmen. Nicht bekannt sind Innenschuhe. welche eine Anpassung des Schuhs an die Fußform der Person, welche den Schuh trägt. zuläßt.

Dadurch kann die erfindungsgemäße heizbare Folie in ähnlicher Weise, wie flexible gedruckte Schaltungen billig hergestellt werden und nachträglich entsprechend der Form des Innenschuhs bzw. Fußes gebogen werden. Die Anordnung mehrerer Widerstandszonen ermöglicht eine selektive Erwärmung des thermoplastischen Kunststoffs im Innenschuh. Die Widerstandsschicht kann aus beliebigen elektrisch leitfähigen Materialien bestehen. Auch Gewebe aus beispielsweise Kohlefasern sind denkbar.The or each heatable film advantageously consists of a flexible plastic layer, is arranged on the at least one resistance layer, the ends of which have at least one, leading connecting line are connected.

  • optionally repeating steps b to d.
  • This represents a simple process variant for adapting the shape of the foot to an inner shoe.

    Alternativ dazu kann die Aufgabe auch durch zeitliche Aufeinanderfolge der folgenden Verfahrensschritte gelöst werden:

In contrast In the above-mentioned procedure, the foot may become warped due to excessive heating stretch, making it impossible to optimally adjust the shape of the foot. That too can strong warming may be uncomfortable.

    Vorteilhafterweise wird bei dem erfindungsgemäßen Verfahren die Temperatur im Innenschuh gemessen und die oder jede heizbaren Folie des Innenschuhs automatisch von der elektrischen Spannungsquelle getrennt, nachdem die für eine gute Verformbarkeit des thermoplastischen Kunststoffs des Innenschuhs notwendige Temperatur erreicht wurde. Somit wird der Fuß und der Innenschuh vor Überhitzung geschützt und andererseits sichergestellt, daß die für eine gute Verformbarkeit des thermoplastischen Kunststoffs des Innenschuhs notwendige Temperatur erreicht wird.In the method according to the invention, the temperature in the Liner measured and the or each heatable film of the liner automatically from the separated after the electrical voltage source for good ductility of the thermoplastic of the liner necessary temperature was reached. Consequently the foot and liner are protected from overheating and, on the other hand, it is ensured that for good deformability of the thermoplastic plastic of the liner necessary temperature is reached.

    Alternativ dazu kann die zur Erwärmung des thermoplastischen Kunststoffs des Innenschuhs auf die für gute Verformbarkeit notwendige Temperatur erforderliche zeit ermittelt werden und die automatischen Trennung der oder jeder heizbaren Folie des Innenschuhs von der elektrischen Spannungsquelle nach einer vorgegebenen Zeitspanne getrennt werden. Dies stellt eine einfachere und billigere, wenngleich eine nicht so sichere und genaue Alternative zur Verwendung von Temperatursensoren dar.Alternatively, it can be used to heat the thermoplastic plastic of the liner at the time required for good ductility and the automatic separation of the or each heatable film of the liner from the electrical voltage source are separated after a predetermined period of time. This represents a simpler and cheaper, albeit not so safe and accurate, alternative for using temperature sensors.

    Die entsprechenden Verfahrensmerkmale können konstruktiv leicht in einem entsprechenden Netzteil zur Versorgung der oder jeder heizbaren Folie des Innenschuhs realisiert werden.The corresponding process features can easily be constructed in a corresponding manner Power supply to supply the or each heatable film of the liner can be realized.

    Die Erfindung wird anhand der beigefügten Abbildungen, welche Ausführungsbeispiele der erfindungsgemäßen Heizfolie und deren Anordnung im Innenschuh zeigen, näher erläutert.The invention is based on the accompanying figures, which embodiments of the show heating film according to the invention and their arrangement in the liner, explained in more detail.

    Fig. 1 zeigt ein Beispiel einer heizbaren Folie 1 in aufgeklapptem Zustand. Im Innenschuh werden die seitlichen spitz zulaufenden Enden der Folie 1 in Richtung der Zehen des Fußes zusammengeklappt. Zur Aussparung der Ferse ist die Folie im unteren, mittleren Bereich ausgenommen. Die Folie 1 besteht aus einem flexiblen Kunststoffmaterial, auf dem ein Widerstandsbelag 2 vorzugsweise mäanderförmig aufgebracht ist. Natürlich sind auch andere Ausführungen der elektrischen Widerstandsheizung möglich. Beispielsweise könnte auch auf oder in der Folie 1 das Widerstandsmaterial in Art eines Gewebes aus beispielsweise Kohlefasern angeordnet sein (nicht dargestellt). Die Enden 7, 8 des Widerstandsbelags 2 sind mit einer Anschlußleitung 3 verbunden, über welche die heizbare Folie 1 mit elektrischer Energie versorgt werden kann. Zu diesem Zweck ist an der Anschlußleitung 3 vorteilhafterweise ein Stecker 4 vorgesehen. Durch den resultierenden Stromfluß in der Widerstandsschicht 2 wird Verlustwärme erzeugt und somit die Folie 1 bzw. der mit der Folie 1 ausgestattete Innenschuh gleichmäßig erwärmt. Bei üblichen thermoplastischen Kunststoffen wird eine gute Verformbarkeit ab Temperaturen oberhalb von 70°C erzielt. Um optimale Verformbarkeit zu erzielen. wird das Material des Innenschuhs auf etwa 110°C aufgeheizt. Dies kann durch Einstellung der Zeit, welche die heizbare Folie 1 mit der Spannungsquelle verbunden ist oder durch Messung der Temperatur mit einem auf der Folie 1 oder im Innenschuh angeordneten Temperatursensor (nicht dargestellt) kontrolliert werden. Nach Erreichen der für die Verformung des Kunststoffmaterials notwendigen Temperatur wird die Heizfolie automatisch oder manuell von der Spannungsversorgung getrennt. Der Innenschuh ist bei dieser Temperatur verformbar und paßt sich daher an die Fußform an. Der Fuß bleibt so lange im Schuh. bis der Innenschuh abgekühlt und nicht mehr verformbar ist. Somit hat sich der Innenschuh optimal an die Form des Fußes angepaßt. Voraussetzung dafür ist, daß die den Widerstandsbelag 2 aufweisende Folie 1 leicht verformbar ist. Andernfalls würden sich unregelmäßige Temperaturverteilungen im Material des Innenschuhs ergeben, wodurch die Verformbarkeit des Innenschuhs unterschiedlich und eine optimale Anpassung an die Fußform nicht möglich wäre. Zu diesem Zweck befinden sich gemäß diesem Ausführungsbeispiel an empfindlichen Stellen des Fußes wie zum Beispiel im Bereich der Knöchel oder der Ferse Einschnitte 6. Perforationen oder dgl. in der Folie 1, die eine leichtere Verformung derselben zulassen. Zum Schutz dieser empfindlichen Regionen des Fußes vor Überhitzung durch die beheizte Folie 1. kann an diesen Stellen eine Aluminiumfolie 5 oder dergleichen zur Wärmeableitung angeordnet sein. Natürlich ist auch möglich, daß die Folie 1 an den empfindlichen Stellen des Fußes vollständig ausgenommen ist.Fig. 1 shows an example of a heatable film 1 in the opened state. In the liner the lateral pointed ends of the film 1 towards the toes of the foot folded up. To cut out the heel, the film is in the lower, middle area except. The film 1 consists of a flexible plastic material on which a Resistance coating 2 is preferably applied in a meandering shape. Of course there are others too Versions of the electrical resistance heating possible. For example, you might as well or in the film 1, the resistance material in the manner of a fabric, for example Carbon fibers can be arranged (not shown). The ends 7, 8 of the resistance covering 2 are connected to a connecting line 3, via which the heatable film 1 with electrical Energy can be supplied. For this purpose, 3 advantageously a connector 4 is provided. Due to the resulting current flow in the Resistance layer 2 generates heat loss and thus the film 1 or that with the film 1 fitted liner evenly heated. With conventional thermoplastic Plastics achieve good formability from temperatures above 70 ° C. Around to achieve optimal deformability. the material of the liner is around 110 ° C heated up. This can be done by adjusting the time that the heatable film 1 with the Voltage source is connected or by measuring the temperature with one on the film 1 or temperature sensor (not shown) arranged in the inner shoe. After reaching the temperature necessary for the deformation of the plastic material the heating foil is automatically or manually disconnected from the power supply. Of the Liner is deformable at this temperature and therefore adapts to the shape of the foot. Of the Foot stays in the shoe for so long. until the liner has cooled and is no longer deformable. Thus, the liner has optimally adapted to the shape of the foot. Prerequisite for this is that the film 1 having the resistance coating 2 is easily deformable. Otherwise there would be irregular temperature distributions in the material of the liner, whereby the deformability of the liner is different and optimal adjustment to the shape of the foot would not be possible. For this purpose are according to this Embodiment in sensitive areas of the foot such as in the area of Ankle or heel incisions 6. Perforations or the like in the film 1, which is a lighter Allow them to deform. To protect these sensitive regions of the foot from Overheating by the heated foil 1. can be an aluminum foil 5 or the like be arranged for heat dissipation. Of course, it is also possible for the film 1 in the sensitive areas of the foot.

    In den Fig. 2a bis 2d werden weitere Ausführungsvarianten für heizbare Folien zur Anwendung in einem Innenschuh in ebener Darstellung gezeigt. Fig. 2a zeigt eine Foliel mit dem darauf angeordneten Widerstandsbelag 2 mit beiderseits drei fingerförmigen Fortsätzen. Der Widerstandsbelag 2 ist auf den Abbildungen nur schematisch gezeigt und kann auch mäanderförmig oder in Form eines Gewebes auf der Folie 1 angeordnet sein. Der Widerstandsbelag 2 ist über eine Anschlußleitung 3 mit dem Stecker 4 verbunden. Die fingerförmigen Fortsätze werden von der Ferse um den Fuß geklappt oder von oben über den Vorderfuß geklappt (siehe Fig. 3a und 3b). Empfindliche Stellen des Fußes, wie zum Beispiel Knöchel werden nicht von der Folie 1 umgeben. Die Gestaltung gemäß Fig. 2a ist durch ihre Flexibilität bei der Anordnung auf dem Fuß und ihre leichte Verformbarkeit gekennzeichnet. Fig. 2b zeigt eine gegenüber der Folie 1 aus Fig. 2a erweiterte Ausführüngsvariante, bei der zusätzlich ein in der Mitte angeordneter Fortsatz der Folie 1 vorgesehen ist, der zur Erwärmung des Innenschuhs im Bereich der vorderen Fußsohle dient. Fig. 2c zeigt eine Variante einer heizbaren Folie 1 für einen Innenschuh, bei dem gegenüber Fig. 2a zwei Widerstandsbeläge 2' und 2" für die beiden Seiten der Folie 1 vorgesehen sind. Die Widerstandsbeläge 2' und 2" enden in verschiedenen Anschlußleitungen 3' und 3" und Steckern 4' und 4". Dadurch ist eine selektive Beheizung des Innenschuhs zur selektiven Anpassung des Innenschuhs an die Fußform möglich. Wenn der Träger des Schuhs der Ansicht ist. daß die Anpassung an die Fußform am Außenfuß optimal ist, während die Anpassung am Innenfuß noch nicht ideal ist, braucht nur der entsprechende Teil der Folie, welche den Innenfuß umgibt, erneut erwärmt werden um auch dort eine optimale Anpassung zu erreichen. Die Anzahl und Gestalt der Widerstandszonen kann beliebig und entsprechend dem jeweiligen Anwendungsfall ausgeführt werden. In Fig. 2d ist ein Beispiel einer heizbaren Folie 1 mit drei Widerstandsbelägen 2', 2" und 2"' mit drei Anschlußleitungen 3', 3" und 3'" sowie drei Steckern 4', 4" und 4"' dargestellt. Der Widerstandsbelag 2" im mittleren Bereich der Folie dient dabei zur Erwärmung des Innenschuhs an der Fußsohle im Zehenbereich. Selbstverständlich kann anstelle der einzelnen Anschlußleitungen 3', 3" und 3'" bzw. anstelle der einzelnen Stecker 4', 4" und 4"' auch nur eine entsprechend mehradrige Anschlußleitung bzw. ein entsprechend mehrpoliger Stecker vorgesehen sein.2a to 2d show further design variants for heatable films Application shown in a liner in a flat representation. Fig. 2a shows a film with the resistance covering 2 arranged thereon with three finger-shaped extensions on both sides. The resistance coating 2 is only shown schematically in the figures and can also be arranged in a meandering shape or in the form of a fabric on the film 1. Of the Resistance coating 2 is connected to connector 4 via a connecting line 3. The Finger-shaped extensions are folded from the heel around the foot or from above over the Forefoot folded (see Fig. 3a and 3b). Sensitive areas of the foot, such as Ankle are not surrounded by foil 1. The design according to FIG. 2a is due to its Flexibility in the arrangement on the foot and their easy deformability are characterized. FIG. 2b shows an embodiment variant expanded compared to the film 1 from FIG. 2a, in which in addition, an extension of the film 1 arranged in the middle is provided, which for Warming the inner shoe in the area of the front sole of the foot. 2c shows one Variant of a heatable film 1 for an inner shoe, in which two compared to Fig. 2a Resistance coatings 2 'and 2 "are provided for the two sides of the film 1. The Resistance pads 2 'and 2 "end in different connecting lines 3' and 3" and Plugs 4 'and 4 ". This allows selective heating of the inner liner for selective Adaptation of the liner to the shape of the foot possible. If the wearer of the shoe is the View is. that the adaptation to the shape of the foot on the outer foot is optimal, while the Adjustment on the inner foot is not yet ideal, only the corresponding part of the film needs, which surrounds the inner foot, are heated again in order to achieve an optimal adjustment there too to reach. The number and shape of the resistance zones can be any and corresponding the respective application. 2d is an example of a heatable Foil 1 with three resistance layers 2 ', 2 "and 2"' with three connecting lines 3 ', 3 "and 3 '"and three plugs 4', 4" and 4 "'shown. The resistance coating 2" in the middle The area of the film is used to heat the liner on the sole of the foot Toe area. Of course, instead of the individual connecting lines 3 ', 3 "and 3 '"or instead of the individual plugs 4', 4" and 4 "'only one accordingly Multi-core connection cable or a corresponding multi-pin connector may be provided.

    In Fig. 3a und 3b sind zwei Beispiele für die Lage einer erfindungsgemäßen heizbaren Folie in Bezug auf den Fuß dargestellt. Je nach Gestalt der Folie 1 mit dem Widerstandsbelag 2 und der Anschlußleitung 3 kann diese vom Fersenbereich um den Fuß 9 geklappt werden, wie aus Fig. 3a ersichtlich. Ebenso ist eine Anordnung entsprechend Fig. 3b möglich, bei der der Fuß 9 von oben mit der Folie 1 versehen wird. Wichtig dabei ist, daß empfindliche Stellen des Fußes von keiner Folie 1 bedeckt sind, bzw. an solchen Stellen entsprechende Einschnitte, Perforationen oder dergleichen an der Folie 1 angeordnet sind. Die Anordnung der Folie 1 im Innenschuh in Bezug auf den Fuß kann auch je nach Anwendungsfall unterschiedlich erfolgen. Beispielsweise sind die Problemzonen des Fußes auch von der Sportart abhängig, und werden sich zum Beispiel beim Skifahren und Bergsteigens sicherlich unterscheiden.3a and 3b are two examples for the position of a heatable film according to the invention in Illustrated with respect to the foot. Depending on the shape of the film 1 with the resistance coating 2 and the connecting line 3, this can be folded from the heel area around the foot 9, as from 3a can be seen. An arrangement according to FIG. 3b is also possible, in which the foot 9 is provided with the film 1 from above. It is important that sensitive areas of the Are not covered by any foil 1, or corresponding incisions at such locations, Perforations or the like are arranged on the film 1. The arrangement of the film 1 in Liner in relation to the foot can also vary depending on the application respectively. For example, the problem areas of the foot also depend on the sport, and will certainly differ, for example when skiing and mountaineering.

    Fig. 4a bis 4c zeigen noch Beispiele für die Anordnung der heizbaren Folie 1 in einem Innenschuh. Fig. 4a zeigt den Schichtaufbau eines Innenschuhs, beispielsweise für einen Skischuh im Querschnitt. Auf die Außenschicht 10 des Innenschuhs folgt eine Isolierschicht 11, welche dazu dient. daß nicht zuviel Wärme der heizbaren Folie 1 nach außen verlorengeht. Zwischen der Isolierschicht 11 und einer Schicht des thermoplastischen Kunststoffs 12 ist die heizbare Folie 1 angeordnet. durch welche der thermoplastische Kunststoff auf die zur Verformung geeigneten Temperatur aufheizbar ist. Gemäß Fig. 4b ist zwischen der Isolierschicht 11 und der heizbaren Folie 1 eine weitere Schicht thermoplastischen Kunststoffs 12 angeordnet. Durch Wahl des Materials und der Schichtdicke des thermoplastischen Kunststoffs 12 kann eine Optimierung des Innenschuhs in Bezug auf die Anpaßbarkeit an die Fußform des Trägers erreicht werden. Fig. 4c zeigt eine Variante eines Schichtaufbaus eines Innenschuhs. bei dem nach der Isolierschicht 11 eine Schicht des thermoplastischen Kunststoffs 12, danach die heizbare Folie 1 und abschließend ein Futter zur Auskleidung der Inneren Oberfläche des Innenschuhs angeordnet ist.4a to 4c show examples of the arrangement of the heatable film 1 in one Liner. 4a shows the layer structure of an inner shoe, for example for one Cross-sectional ski boot. An insulating layer follows the outer layer 10 of the inner shoe 11, which serves. that not too much heat of the heatable film 1 is lost to the outside. Between the insulating layer 11 and a layer of the thermoplastic 12 is the heatable film 1 arranged. through which the thermoplastic plastic to the Deformation suitable temperature is heated. 4b is between the Insulating layer 11 and the heatable film 1 a further layer of thermoplastic 12 arranged. By choosing the material and the layer thickness of the thermoplastic Plastic 12 can optimize the liner in terms of adaptability to the Can be achieved. 4c shows a variant of a layer structure of a Liner. in which after the insulating layer 11 a layer of thermoplastic Plastic 12, then the heatable film 1 and finally a lining for lining the Inner surface of the liner is arranged.

    Die Gestaltung der Folie sowie deren Anordnung im Innenschuh ist nicht auf die dargestellten Beispiele beschränkt, sondern kann im Rahmen der Erfindung beliebig verändert werden. Natürlich kann die Folie im Innenschuh auch aus mehreren Teilen bestehen.The design of the film and its arrangement in the liner is not on the shown Examples limited, but can be changed as desired within the scope of the invention. Of course, the film in the inner shoe can also consist of several parts.
