Description

Die Erfindung bezieht sich auf eine Spreizfußstütze aus Kunststoff, insbesondere aus zusammengepreßten, mit einem thermoplastischen Kunstharz, wie Anilinharz, imprägnierten Faserstoffen, wie Preßpapier und/oder Fiber.The invention relates to a splayfoot support made of plastic, in particular from compressed, with a thermoplastic synthetic resin such as aniline resin, impregnated fibrous materials such as press paper and / or fiber.

Während es bei gewöhnlichen Plattfußeinlagen, d. h. bei solchen Fußstützen, die lediglich das (durchgetretene) Längsgewölbe des Fußes abstützen sollen, allgemein bekannt ist, die Einlage federnd auszubilden, damit sie beim Gehen entsprechend der Fußbelastung in der Längsrichtung nachgibt, sind die bisher gebräuchlichen Spreizfußeinilagen meistens so beschaffen, daß sie nur in der Querrichtung ein (und zwar starres) Gewölbe zur Stützung des Spreizfußes aufweisen, in der Längsrichtung jedoch plan aufliegen, also überhaupt kein Längsgewölbe haben. Es sind aber auch solche vorzugsweise aus Metall bestehende Spreizfußeinlagen nicht mehr neu, die außer einem starren Quergewölbe noch ein ebenfalls starres bzw. nur ganz schwach federndes LängsgeNvölbe aufweisen.While with ordinary flat foot insoles, i. H. with such footrests, which are only intended to support the (penetrated) longitudinal arch of the foot, in general it is known to make the insert resilient so that it is accordingly when walking The splayfoot inserts that have been used up to now have been used to give way to the load on the foot in the longitudinal direction mostly designed in such a way that they have a (and rigid) vault only in the transverse direction to support the splayfoot, but lie flat in the longitudinal direction, so have no longitudinal vault at all. But those are also preferably off Metal existing splayfoot insoles are no longer new, except for a rigid transverse vault still have a likewise rigid or only very weakly resilient longitudinal vault.

Die Spreizfußstütze gemäß der Erfindung unterscheidet sich von den bekannten Spreizfußeinlagen dadurch, daß die Wandstärke der mit einem Quer-und einem Längsgewölbe versehenen Fußstütze derart schwach gehalten ist, daß die Fußstütze in der Längsrichtung entsprechend der Fußbelastung so stark nachgibt, daß sie im Falle eines Senkfußes bei jedem Schritt unter der Wirkung der vollen Fußbelastung flach getreten wird, dennoch aber in der Querrichtung stets starr (unnachgiebig) bleibt, so daß der Spreizfuß auch während der größten Belastung dauernd abgestützt ist.The splayfoot support according to the invention differs from the known splayfoot inserts in that the wall thickness of the with a transverse and a Longitudinal arch provided footrest is kept so weak that the footrest in the longitudinal direction according to the foot load gives so much that it is in Fall of a arches with every step under the effect of the full load of the foot is kicked flat, but always rigid in the transverse direction (unyielding) remains, so that the splayfoot is continuously supported even during the greatest load is.

Durch diese Ausbildung der Spreizfußstütze erreicht man den Vorteil, daß die Sohlenmuskeln des Fußes zu eigener Tätigkeit angelegt werden, wobei aber, was besonders wichtig ist, das Fßquergewölbe dauernd. angehoben und abgestützt bleibt, mit (lern Ergebnis, daß das Tragen einer solchen SpreizfußeinIage im Laufe der Zeit zu einer Beseitigung oder doch wenigstens zu einer Milderung der Fußbeschwerden führt.This design of the splayfoot support has the advantage of that the sole muscles of the foot are used for their own activity, but what is particularly important is the transverse arch of the foot. remains raised and supported, with the result that wearing such a splayfoot insert over time to eliminate or at least to alleviate the foot complaints leads.

In der Zeichnung ist der Erfindungsgegenstand beispielsweise veranschaulicht; es zeigt Fig. i eine Spreizfußstütze gemäß der Erfindung in Draufsicht, Fig. 2 eirve Vorderansicht zu Fig. i, in unbelastetem Zustande der Fußstütze, Fig. 3 eine der Fig. 2 entsprechende .Ansicht. jedoch bei belasteter Fußstütze, Fig.:I einen. Querschnitt nach der Linie IV-IN' der Fig. i.In the drawing, the subject matter of the invention is illustrated, for example; It shows Fig. 1 a splayfoot support according to the invention in plan view, Fig. 2 eirve Front view of FIG. I, in the unloaded state of the footrest, FIG. 3 one of the Fig. 2 corresponding .Ansicht. but with a loaded footrest, Fig.:I one. cross-section according to the line IV-IN 'of Fig. i.

Die dargestellte Fußstütze besteht aus Anilinharzpreßpapier sowie aus Anilinharzfiber, d. h. sie ist in bekannter Weise aus finit Aailinharz getränkten blattförmigen Faserstoffen unter Druck und Wärme zusammengepreßt. Im Gegensatz zu bekanntem Spreizfußstützen ist jedoch die Wandstärke der Fußstütze so gering, z. B. nur o,5 mm, daß zwar das kurze, gegebenenfalls noch verstärkte Quergewölbe (Fig. _1), das den Spreizfuß stützt, auch unter größter Belastung unbedingt starr (unnachgiebig) bleibt, daß aber anderseits das Längsgewölbe (Fig.2) entsprechend der Fußbelastung nachgibt, d. h. im Falle eines Senkfußes bei jedem Schritt unter der Wirkung der vollen Fußbelastung in Richtung des in Fig. 3 eingezeichneten Pfeiles flach getreten wird, um sich beim Heben des Fußes wieder in die Ausgangslage zurückzuwölben, ein Vorgang, der sich bei jedem Schritt wiederholt.The illustrated footrest is made of aniline resin press paper as well made of aniline resin fiber, d. H. it is soaked in a known manner from finite algin resin sheet-like fibers compressed under pressure and heat. In contrast to known splayfoot supports, however, the wall thickness of the footrest is so small, z. B. only 0.5 mm, that although the short, possibly reinforced transverse vault (Fig. _1), which supports the splayfoot, absolutely rigid (unyielding) even under the greatest loads remains, but on the other hand, the longitudinal arch (Fig.2) according to the foot load yields, d. H. in the case of arches, with every step under the action of full foot load in the direction of the arrow shown in Fig. 3 stepped flat to arch back into the starting position when you lift your foot Process that is repeated with each step.
