Abstract
Description
Die Erfindung betrifft individuell anpaßbare orthopädische Schuheinlagen aus Leder oder Kunstleder gemäß dem Oberbegriff des Anspruchs 1.The invention relates to individually adaptable orthopedic shoe inserts made of leather or synthetic leather according to the preamble of claim 1.
Zur Korrektur und Stützung von Fehlstellungen des Fußes, beispielsweise bei Plattfüßen, Senkfüßen, Senk-Spreizfüßen, Hohlfüßen und dergleichen, verordnet der Facharzt Einlagen. Die Anfertigung dieser Einlagen erfolgt durch den Orthopädie-Schuhmacher oder Orthopädie-Techniker auf der Basis eines vom Fuß des Patienten abgenommenen Gipsabdrucks, eines gegebenenfalls bereits vorhandenen Patientenleistens oder nach Maß.The specialist prescribes insoles to correct and support malpositions of the foot, for example in the case of flat feet, flat feet, flat spreading feet, hollow feet and the like. These insoles are made by the orthopedic shoemaker or orthopedic technician on the basis of a plaster cast that has been removed from the patient's foot, an existing patient last, or made to measure.
Bei der Fertigung von Einlagen, insbesondere solchen aus Leder oder Kunstleder, werden stützende Einlagenkerne verwendet, die in ihrer Form und Größe an den kranken Fuß des Patienten angepaßt werden. Für die Herstellung dieser Einlagenkerne liefert die Industrie vorgeformte Platten aus thermoplastischem Kunststoff, die in vielen Fällen auch mit Verstärkungsfasern gefüllt sind. Diese Platten werden erwärmt und auf den Gipsabguß gepreßt. Bei etwas Glück und viel Geschick hat die Oberseite der Platte nach dem Erkalten die dem Patientenfuß entsprechende Wölbung.In the production of insoles, in particular those made of leather or synthetic leather, supporting insert cores are used, the shape and size of which are adapted to the patient's sick foot. For the production of these insert cores, industry supplies preformed sheets made of thermoplastic material, which in many cases are also filled with reinforcing fibers. These plates are heated and pressed onto the plaster cast. If you are lucky and have a lot of skill, the top of the plate has the curvature corresponding to the patient's foot after cooling.
In diesem Zustand sind die Formlinge jedoch noch nicht verwendbar. Vielmehr müssen Form und Größe einerseits und die richtige Materialverteilung andererseits noch herausgearbeitet werden. Hierzu wird das überschüssige Material mit Hilfe von Messern oder Schleifscheiben abgearbeitet. Dieser Vorgang erfordert viel Erfahrung und viel Fingerspitzengefühl. Wird an der falschen Stelle zuviel Material abgenommen, war die ganze bisherige Arbeit umsonst; der Einlagenkern muß neu erstellt werden, andernfalls wäre eine damit fertiggestellte Einlage zur Behebung der Fußschäden ungeeignet.In this state, however, the moldings cannot yet be used. Rather, shape and size on the one hand and the correct material distribution on the other hand still have to be worked out. For this purpose, the excess material is worked off with the help of knives or grinding wheels. This process requires a lot of experience and tact. If too much material is taken from the wrong place, all the work so far has been wasted; the deposit core must be recreated, otherwise it would be a completed insert is unsuitable for repairing foot damage.
Es versteht sich, daß das Herausarbeiten der Endform aus dem Rohling zeitaufwendig ist. Dabei entsteht auch eine reichliche Menge an Kunststoffabfällen, meist in Staubform, deren Entsorgung immer schwieriger wird, insbesondere dann, wenn der Kunststoff faserverstärkt ist.It goes without saying that working out the final shape from the blank is time-consuming. This also creates an abundance of plastic waste, mostly in dust form, the disposal of which is becoming increasingly difficult, especially when the plastic is fiber-reinforced.
Außer den beschriebenen ebenen, nur im Umriß an die Fußform angenäherten Kunststoffplatten liefert die Industrie auch Platten für orthopädische Einlagen, deren Oberseite bereits etwa entsprechend der Normalfußsohle vorgeformt ist. Durch diese Vorformung ist die Anpassung an den Gipsabguß etwas erleichtert. Die Endbearbeitung unterscheidet sich jedoch in keiner Weise von der oben beschriebenen.In addition to the flat plastic plates described, which only approximate the shape of the foot, the industry also supplies plates for orthopedic insoles, the upper side of which is already pre-shaped to match the normal sole of the foot. This preforming somewhat facilitates the adaptation to the plaster cast. However, the finish is no different from that described above.
Aus der DE-A-31 32 354 sind Rohlinge für orthopädische Einlagen bekannt, die ebenfalls aus einem plattenförmigen Material wie Leichtmetall oder Kunststoff bestehen, wobei die Oberseite bereits vorgeformt ist. Diese Vorformung ist jedoch nicht einheitlich, sondern soll individuell auf die zwei grundsätzlichen Fußtypen, den Hohlfuß und den Plattfuß, angepaßt sein, was sich in einer abweichenden Höhe der stützenden Wölbungen - bei Plattfuß flacher, bei Hohlfuß höher - und einer unterschiedlichen Position des Wölbungsmaximums - näher an der Ferse beim Plattfuß, näher bei den Zehen beim Hohlfuß - ausdrückt. Gemäß der in der DE-A-31 32 354 gegebenen Begründung soll es möglich sein, zu jedem Patientenfuß den genau passenden Rohling aus dem vom Orthopädie-Schuhmacher bzw. -Techniker vorzuhaltenden großen Vorrat auszusuchen. Damit würde zwar der Arbeitsgang des Anpassens der Wölbung entsprechend dem Gipsabguß entfallen; die individuelle Endbearbeitung durch Wegnahme von überschüssigem Material bleibt jedoch.From DE-A-31 32 354 blanks for orthopedic insoles are known, which also consist of a plate-like material such as light metal or plastic, the upper side being preformed. However, this preforming is not uniform, but should be individually adapted to the two basic foot types, the hollow foot and the flat foot, which is reflected in a different height of the supporting curvatures - flat for flat feet, higher for hollow feet - and a different position of the arch maximum. closer to the heel at the flat foot, closer to the toes at the hollow foot - expresses. According to the reason given in DE-A-31 32 354, it should be possible to choose the right blank for each patient's foot from the large stock to be kept by the orthopedic shoemaker or technician. This would eliminate the process of adjusting the curvature in accordance with the plaster cast; however, individual finishing by removing excess material remains.
Zwar ist es prinzipiell möglich, die verformten Platten ohne Nachbearbeitung zu verwenden, wie es in der Praxis auch vielfach geschieht. Bedingt durch die einheitliche Stärke des Plattenmaterials von beispielsweise 6 mm, zu der sich die Stärke des Leders usw. addiert, bekommt die fertige Einlage eine solche Höhe, daß sie nur noch in Spezialschuhen getragen werden kann. Solche Spezialschuhe zeichnen sich jedoch nicht durch besondere Eleganz aus.In principle, it is possible to use the deformed plates without post-processing, as is often the case in practice. Due to the uniform thickness of the plate material of, for example, 6 mm, to which the thickness of the leather etc. is added, the finished insert is of such a height that it can only be worn in special shoes. However, such special shoes are not characterized by particular elegance.
Durch die individuelle Nachbearbeitung der Plattenrohlinge wird das Kunststoffmaterial an den wenig belasteten Stellen, beispielsweise unter der Ferse und an den Übergängen, dünn gehalten, ohne daß an den Stützpunkten die Festigkeit leidet, so daß die fertige Einlage nur noch einen Bruchteil der Höhe hat und in modischen Schuhen getragen werden kann.Due to the individual reworking of the plate blanks, the plastic material is kept thin at the low-stress points, e.g. under the heel and at the transitions, without the strength suffering at the support points, so that the finished insert is only a fraction of the height and in fashionable shoes can be worn.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, orthopädische Einlagen der eingangs genannten Art anzugeben, deren geringe Dicke besonders an der Ferse und an den Übergangsstellen eine Benutzung in modischen Schuhen ermöglicht, deren Einlagenkerne jedoch nicht materialabnehmend nachbearbeitet werden müssen.The present invention is based on the object of specifying orthopedic insoles of the type mentioned at the beginning, the small thickness of which enables use in fashionable shoes, particularly at the heel and at the transition points, but whose insole cores do not have to be reworked to remove material.
Diese Aufgabe wird gelöst durch eine gattungsgemäße orthopädische Schuheinlage mit den Merkmalen gemäß Kennzeichen des Anspruchs 1.This object is achieved by a generic orthopedic shoe insert with the features according to the characterizing part of claim 1.
Vorteilhafterweise ist die Unterseite des Einlagenkerns im Fersen- und im Gelenkbereich an die Schuhinnenfläche angepaßt.The underside of the insert core in the heel and in the joint area is advantageously adapted to the inside of the shoe.
Damit ergeben sich die Vorteile, daß die Herstellung fabrikmäßig und in Großserien erfolgen kann, wobei als Modell nur jeweils einmal ein Einlagenkern optimal herausgearbeitet werden muß, mit der Folge, daß Paßform und Stützfunktion optimal und die Preise minimal sind. Dank der Verwendung von thermoplastischem Kunststoff ist es darüber hinaus möglich, in besonderen Fällen, d. h. bei Problemfüßen, in der herkömmlichen Weise eine individuelle Anpassung des Einlagenkerns anhand des Gipsabgusses durchzuführen, wobei jedoch jede nachträgliche Materialabnahme oder -zugabe entfällt.This results in the advantages that the production can take place in the factory and in large series, with an insert core only being optimal once as a model must be worked out, with the result that fit and support function are optimal and the prices are minimal. Thanks to the use of thermoplastic, it is also possible in special cases, ie with problem feet, to carry out an individual adjustment of the insert core using the plaster cast in the conventional manner, however any subsequent material removal or addition is omitted.
Darüber hinaus ist es möglich, das Kunststoffmaterial aus ausgedienten Einlagen zu recyclen. Dies gilt insbesondere dann, wenn das Kunststoffmaterial frei von Verstärkungsfasern ist. Auch ist eine klebstofffreie Weiterverarbeitung mit vorgefertigten Einlagentaschen möglich.In addition, it is possible to recycle the plastic material from used deposits. This is especially true when the plastic material is free of reinforcing fibers. Adhesive-free processing with prefabricated insert pockets is also possible.
Überraschenderweise hat sich gezeigt, daß die spritzgegossenen Einlagenkerne dank dieser Herstellungsart eine berechenbare und gleichbleibende Festigkeitsstruktur aufweisen, gleichzeitig weich-elastische und somit angenehme Kantenübergänge zum Fuß besitzen und sich flexibel an die Bewegungen von Fuß und Schuh beim Gehen sowie insbesondere an die jeweilige Gelenksprengung des Schuhs anpassen. Gleichzeitig bleibt jedoch die medizinisch gebotene optimale Stützfunktion in allen Fällen gewährleistet.Surprisingly, it has been shown that thanks to this type of production, the injection-molded insert cores have a predictable and constant strength structure, at the same time have soft-elastic and thus pleasant edge transitions to the foot and are flexible in terms of the movements of the foot and shoe when walking and in particular the respective joint heel of the shoe to adjust. At the same time, however, the medically required optimal support function is guaranteed in all cases.
Die Fertigstellung der Einlagen erfolgt ganz in der herkömmlichen Machart. Polster, Pelotten, Bodenverkleidungsteile usw. werden je nach Bedarf nach maßgenau eingearbeitet.The insoles are completed in the conventional manner. Upholstery, pads, floor cladding parts, etc. are incorporated according to the needs and dimensions.
Bei dreiviertel- und langsohligen Einlagen, Bezügen, Decken oder Taschen, auch mit weichen Vorfußpolstern, wird gemäß einer bevorzugten Ausgestaltung der Erfindung die Einlagendecke im Bereich der Ballen oder der empfindlichen Mittelfußköpfchen geschlitzt, insbesondere kreuzgeschlitzt. Dadurch wird die Wirkung der eingearbeiteten Polster erheblich erhöht, ohne daß diese Schlitzung auch von empfindlichen Füßen nachteilig wahrgenommen würde. Auch wird die Haltbarkeit der Einlagen dadurch nicht beeinträchtigt.In the case of three-quarter and slow-soled insoles, covers, blankets or bags, even with soft forefoot pads, according to a preferred embodiment of the invention, the insert cover is in the area of the balls or the sensitive ones Slotted metatarsal heads, especially cross-slotted. As a result, the effect of the incorporated upholstery is considerably increased without this slitting being perceived disadvantageously even by sensitive feet. The durability of the inserts is not affected.

Die Fig. 1 und 2 zeigen im Spritzgußverfahren aus thermoplastischem Kunststoff in der endgültigen Form spritzgegossene Einlagenkerne 2, im Fall der Fig. 1 für die Versorgung von Hohlfüßen, im Fall der Fig. 2 für die Versorgung von Plattfüßen. Im Bereich der Abstützungspunkte 3 ist die Materialstärke hoch, um eine optimale Stützfunktion für den kranken Fuß zu gewährleisten, andererseits aber noch ausreichend gering, damit der gesamte Einlagenkern 2 sehr elastisch bleibt für eine optimale Anpassung an die Sprengung des Schuhs und die Bewegungen von Fuß und Schuh beim Gehen. Im Fersenbereich 5 ist das Material praktisch nur noch hauchdünn, da das Gewicht hier unmittelbar auf die Brandsohle und den Absatz des Schuhs abgetragen wird. Der umlaufende Rand des Einlagenkerns 2, insbesondere jedoch der Übergang 4 zum Vorfußbereich ist auslaufend gestaltet, um unerwünschte Druckbelastungen der Füße ebenso zu verhindern wie Beschädigungen des Schuhs oder auch der Einlage selbst.1 and 2 show in the injection molding process made of thermoplastic material in the final form, injection-molded
Die Unterseite des Einlagenkerns 2 ist optimal an die Schuhinnenfläche angepaßt, d. h. im Fersen- und im Gelenkbereich im wesentlichen plan.The underside of the
Die Fig. 3 und 4 zeigen Einlagenkerne 2', die aus thermoplastischem Kunststoff in der Endform spritzgegossen sind, in diesem Fall jedoch mehr als Schaleneinlage für die Versorgung von Kinderfüßen bestimmt. Bei Kindern besteht wegen der noch bildsamen Knochenstruktur die Möglichkeit, Fehlstellungen bleibend zu korrigieren, was durch die Schalenform begünstigt wird.3 and 4 show insert cores 2 ', which are injection molded in the final form from thermoplastic material, but in this case, more intended as a shell insert for the care of children's feet. In children there is the possibility of permanently correcting malpositions due to the still flexible bone structure, which is favored by the shell shape.
Gerade bei Kindern besteht die Notwendigkeit, die korrigierenden Einlagen nach relativ kurzer Tragezeit wieder auszuwechseln. Bei Verwendung der erfindungsgemäßen Einlagenkerne ist es nun möglich, das Material zu recyceln, d. h. zu zerkleinern und neu zu verspritzen. In diesen Fällen fällt also bei der Verwendung der erfindungsgemäßen Einlagenkerne überhaupt kein Kunststoffabfall mehr an.Children, in particular, have to replace the corrective insoles after a relatively short wearing time. When using the insert cores according to the invention, it is now possible to recycle the material, ie to shred it and spray it again. In these cases, there is no longer any plastic waste when using the insert cores according to the invention.
Fig. 5 zeigt eine Draufsicht auf eine fertigstellte langsohlige Einlage 1. Die Einlagendecke 6 besitzt im Vorfußbereich, insbesondere im Bereich der meist sehr empfindlichen Mittelfußköpfchen, eine Kreuzschlitzung 7, dank derer eingearbeitete Ballenpolster optimal zur Geltung kommen, ohne daß die Schlitzung 7 selbst den Fuß stört oder die Haltbarkeit der Einlage 1 beeinträchtigt.Fig. 5 shows a plan view of a finished slow-soled insert 1. The insert cover 6 has a cross-slit 7 in the forefoot area, in particular in the area of the usually very sensitive metatarsal heads, thanks to which integrated ball pads come into their own without the
Dank der Herstellung im Spritzgußverfahren und der optimalen Verteilung des Kunststoffmaterials an die zu stützenden Stellen kann die Menge des Kunststoffmaterials insgesamt klein gehalten werden, ebenso die Höhe. Dadurch wird es möglich, Einlagen in vielen modischen Konfektionsschuhen zu verwenden und auf die bisher fast immer erforderlichen Spezialschuhe für lose Einlagen zu verzichten.Thanks to the injection molding process and the optimal distribution of the plastic material to the areas to be supported, the total amount of plastic material can be kept small, as can the height. This makes it possible to use insoles in many fashionable ready-made shoes and to dispense with the special shoes for loose insoles that have almost always been required.
Durch den völligen Wegfall der materialabnehmenden Bearbeitung werden nicht nur Zeit und Kosten gespart, sondern auch die Abfallmenge und die Verletzungsgefahren verringert. Die orthopädisch entscheidende Stützfunktion ist nicht nur gewährleistet, sondern dank der optimalen Herstellung der Einlagenkerne optimiert.The complete elimination of material-removing processing not only saves time and money, but also reduces the amount of waste and the risk of injury. The orthopedically crucial support function is not only guaranteed, but also optimized thanks to the optimal production of the insert cores.
