Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Schuhzubehörs mit mindestens teilweise beflockter Oberfläche der im Oberbegriff des Anspruchs 1 genannten Gattung sowie ein Schuhzubehör nach dem Oberbegriff des Anspruchs 8.The invention relates to a method for producing a shoe accessory with at least partially flocked surface of the type mentioned in the preamble of claim 1 and a shoe accessory according to the preamble of claim 8.

Beim Tragen von Schuhen spielt neben der Bequemlichkeit auch die Hygiene eine große Rolle. Das Innenfutter der Schuhe nimmt beim Tragen Feuchtigkeit auf. Diese Feuchtigkeit wird im unbenutzten Zustand nur langsam wieder abgegeben. Herkömmliche Schuhspanner oder dergleichen aus Kunststoff beschleunigen die Trocknung nicht. Der Innenbereich eines Schuhs bildet im Zusammenspiel mit Fußschweiß und anderer Feuchtigkeit einen Nährboden für Infektionskeime. Neben Bakterien können sich vor allem Pilze ansiedeln. Dies führt dazu, dass ein erheblicher Prozentsatz der Bevölkerung unter Fußpilz leidet. Außerdem entsteht eine sehr unangenehme Geruchsbildung.When wearing shoes, in addition to comfort, hygiene also plays a major role. The inner lining of the shoes absorbs moisture when worn. This moisture is released slowly when not in use. Conventional shoe trees or the like made of plastic do not accelerate the drying. The inner area of a shoe, together with foot sweat and other moisture, forms a breeding ground for infectious germs. In addition to bacteria, mushrooms can settle especially. As a result, a significant percentage of the population suffers from athlete's foot. It also creates a very unpleasant odor.

Im Dokument DE 20 2006 014 900 U1 ist ein Schuhzubehör beschrieben, bei dem zumindest ein Teil der Oberfläche des Schuhzubehörs eine Beflockung mit einem antibakteriellen Material aufweist. Das Material der Beflockung hat eine feuchtigkeitspuffernde Wirkung. Die Beflockung ist auf einem festen Körper in einem für eine innere Oberfläche des Schuhs vorgesehenen Kontaktbereich aufgebracht.In the document DE 20 2006 014 900 U1 a shoe accessory is described in which at least a portion of the surface of the shoe accessory has a flocking with an antibacterial material. The flocking material has a moisture-buffering effect. The flocking is applied to a solid body in a contact area provided for an inner surface of the shoe.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung eines Schuhzubehörs der im Oberbegriff des Anspruchs 1 genannten Gattung sowie ein so erzeugtes Schuhzubehör zu schaffen, wobei die Funktion als Feuchtigkeitsspeicher gegeben und die Geruchsbildung im Schuh verringert ist.The invention has for its object to provide a method for producing a shoe accessory of the type mentioned in the preamble of claim 1 and a shoe accessory so produced, wherein the function is given as a moisture storage and the odor in the shoe is reduced.

Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 und durch ein Schuhzubehör mit den Merkmalen des Anspruchs 8 gelöst.This object is achieved by a method having the features of claim 1 and by a shoe accessory having the features of claim 8.

Bei dem erfindungsgemäßen Verfahren wird ein Gemisch aus einem Kleber und biologisch aktiven Silberionen erzeugt, das dann auf die zur Beflockung vorgesehene Oberfläche eines festen Körpers aufgetragen wird. Die Beflockung der Oberfläche mit einem Viskose Flock erfolgt in einem elektrischen Feld, damit sich die Fasern des Viskose Flocks ausrichten und von der Oberfläche des festen Körpers abstehen. Überschüssige Fasern werden ausgeblasen, bevor eine Trocknung des beflockten, festen Körpers in unterschiedlichen Temperaturzonen erfolgt. Die biologisch aktiven Silberionen im Gemisch wirken einer Geruchsbildung entgegen.In the method of the invention, a mixture of an adhesive and biologically active silver ions is produced, which is then applied to the flocking surface of a solid body. The flocking of the surface with a viscose flock takes place in an electric field, so that the fibers of the viscose flock align themselves and protrude from the surface of the solid body. Excess fibers are blown out before drying the flocked, solid body in different temperature zones. The biologically active silver ions in the mixture counteract odor formation.

Zumindest ein Teil der Oberfläche des Schuhzubehörs weist eine Beflockung mit einem feuchtigkeitspuffernden Material auf. Das feuchtigkeitspuffernde Material ist in die Beflockung eingebettet. Vorteilhaft besteht die Beflockung selbst aus einem feuchtigkeitspuffernden und antibakteriellen Kunststoff. Alternativ kann die Beflockung auch aus natürlichen Fasern mit einem antibakteriell wirkenden Zusatz bestehen, beispielsweise aus Baumwolle. Die Beflockung kann auf beliebig dreidimensional geformte Oberflächen angebracht werden und ist dadurch besonders für einen Kontaktbereich des Schuhzubehörs mit einer inneren Oberfläche des Schuhs geeignet.At least part of the surface of the shoe accessory has flocking with a moisture buffering material. The moisture-buffering material is embedded in the flocking. Advantageously, the flocking itself consists of a moisture-buffering and antibacterial plastic. Alternatively, the flocking also consist of natural fibers with an antibacterial additive, such as cotton. The flocking can be applied to any three-dimensionally shaped surfaces and is thus particularly suitable for a contact area of the shoe accessory with an inner surface of the shoe.

Die Beflockung nimmt viel Feuchtigkeit auf und unter gegebenen Umständen gibt die Beflockung die Feuchtigkeit auch wieder ab. Der Trocknungsprozess des Schuhs wird beschleunigt, wodurch bakteriellen Keimen die Lebensgrundlage entzogen wird. Ein solches Material weist darüber hinaus eine deutliche antibakterielle Wirkung durch bio-physikalische Vorgänge auf. Die makromolekulare Struktur der Beflockung weist eine positive Oberflächenladung auf, die nicht abgenutzt oder verbraucht wird, und die in Verbindung mit negativer elektrischer Ladung von Keimen zu deren Abtötung führt. Durch die biologisch aktiven Silberionen und das Material der Beflockung ist ein wirksames Mittel zur geruchsbindenden, feuchtigkeitsregulierenden und keimtötenden Schuhpflege geschaffen.The flock absorbs a lot of moisture and under given circumstances flocking also releases the moisture. The drying process of the shoe is accelerated, whereby bacterial germs are deprived of their livelihood. Such material also has a marked antibacterial effect by bio-physical processes. The macromolecular structure of the flock has a positive surface charge which is not worn or consumed and which is associated with negative electric charge of Germs leading to their killing. The biologically active silver ions and the flocking material provide an effective means of odor-binding, moisture-regulating and germicidal shoe care.

Die Fig. 1 zeigt in perspektivischer Darstellung ein Schuhzubehör am Beispiel eines Schuhspanners 1. Der Schuhspanner 1 ist in der gezeigten Ausführung zum Spannen von Halbschuhen vorgesehen. Außer für Halbschuhe, Sportschuhe oder dergleichen kann das erfindungsgemäße Schuhzubehör für Schuhe in beliebiger Ausführung einschließlich Stiefel, Pumps oder dergleichen vorgesehen sein. Der Schuhspanner 1 umfasst einen Formkörper 8 entsprechend dem Zehen- und Mittelfußbereich eines nicht dargestellten Schuhs sowie eine Fersenstütze 10 für den Fersenbereich des Schuhs. Der Formkörper 8 ist ein fester Körper und besteht vorzugsweise aus einem Schaumstoff, beispielsweise aus Polyol und Isocyanat.The Fig. 1 shows a perspective view of a shoe accessory on the example of a shoe tree 1. The shoe trees 1 is provided in the embodiment shown for tensioning of shoes. Except for loafers, sports shoes or the like, the shoe accessory according to the invention for shoes can be provided in any design including boots, pumps or the like. The shoe tensioner 1 comprises a shaped body 8 corresponding to the toe and midfoot region of a shoe, not shown, and a heel support 10 for the heel region of the shoe. The shaped body 8 is a solid body and preferably consists of a foam, for example of polyol and isocyanate.

Die Fersenstütze 10 ist mittels eines elastischen Federelements 9 am Formkörper 8 befestigt. Im eingesetzten Zustand drückt die Fersenstütze 10 den Formkörper 8 über die Federkraft des elastischen Federelements 10 in den vorderen Bereich des nicht dargestellten Schuhs. Eine obere dreidimensional geformte und der Form des Schuhs angepasste Oberfläche des Formkörpers 8 bildet einen Kontaktbereich 5, der im eingesetzten Zustand des Schuhspanners 1 an der inneren Oberfläche des Schuhs flächig anliegt. Der Kontaktbereich 5 des Formkörpers 8 weist eine Beflockung 4 mit einem feuchtigkeitspuffernden Material auf.The heel support 10 is fixed by means of an elastic spring element 9 on the shaped body 8. In the inserted state, the heel support 10 presses the molded body 8 via the spring force of the elastic spring element 10 in the front region of the shoe, not shown. An upper three-dimensionally shaped and adapted to the shape of the shoe surface of the molding 8 forms a contact area 5, which rests flat in the inserted state of the shoe tensioner 1 on the inner surface of the shoe. The contact region 5 of the shaped body 8 has a flocking 4 with a moisture-buffering material.

Im gezeigten Ausführungsbeispiel besteht die Beflockung 4 aus einem auf den Kontaktbereich 5 aufgebrachten Viskose Flock. Die Beflockung ist mittels eines geeigneten Klebers, insbesondere eines Dispersionsklebstoffs an dem Formkörper 8 befestigt. Im eingesetzten Zustand nimmt die Beflockung 4 Feuchtigkeit von der inneren Oberfläche des Schuhs auf und speichert diese, wodurch das Feuchtigkeitsniveau im zuvor getragenen Schuh gesenkt wird. Durch die biologisch aktiven Silberionen im Kleber werden Geruchsstoffe gebunden. Die Verminderung des Feuchtigkeitsniveaus verringert die Gefahr der Ausbreitung von bakteriellen Keimen. Die antibakterielle Wirkung der Beflockung 4 aus Viskose Flock reduziert das Keimwachstum. Nach der Entnahme des Schuhspanners 1 gibt die als Feuchtigkeitspuffer wirkende Beflockung 4 die gespeicherte Feuchtigkeit in kurzer Zeit an die Umgebung ab. Der schnell abgetrocknete Schuhspanner 1 kann schon nach kurzer Zwischenlagerung erneut in ein weiteres paar Schuhe eingesetzt werden.In the exemplary embodiment shown, the flocking 4 consists of a viscose flock applied to the contact region 5. The flocking is attached to the molded body 8 by means of a suitable adhesive, in particular a dispersion adhesive. When inserted, the flocking 4 absorbs and stores moisture from the inner surface of the shoe, thereby lowering the level of moisture in the previously worn shoe. Due to the biologically active silver ions in the adhesive, odors are bound. The reduction in moisture level reduces the risk of bacterial sprouting. The antibacterial effect of flocking 4 made of viscose flock reduces the growth of germs. After removing the shoe tensioner 1 acts as a moisture buffer flocking 4 the stored moisture in a short time to the environment. The quickly dried shoe trees 1 can be used again after a short interim storage in another pair of shoes.

Zur Herstellung des Schuhzubehörs am Beispiel des Schuhspanners 1 gemäß Fig. 1 werden zur Erzeugung des festen Körpers zunächst die Rohmaterialen Polyol und Isocyanat in mit Trennmitteln behandelte Formen injiziert. Das Verhältnis von Polyol zu Isocyanat beträgt vorzugsweise 3:1. Die Reaktion der Komponenten erfolgt unter einer Wärmestrecke. Nach Aushärtung des Schaumstoffmaterials wird der so gebildete Formkörper 8 aus der Form entnommen. Der Kleber, insbesondere ein Dispersionsklebstoff, wird mit einem Zusatz von biologisch aktiven Silberionen und, falls eine bestimmt Farbe der Beflockung 4 gewünscht wird, mit Farbpaste gemischt. Der Anteil des Silberionenzusatzes kann zwischen 0,2% und 0,7% betragen, vorzugsweise ist ein Anteil von 0,5 % vorgesehen. Das Gemisch des auf diese Weise vorbehandelten Klebers wird in einen Behälter gegeben und bildet so ein Tauchbad für den Formkörper 8. Der Formkörper 8 wird auf eine Aufnahmevorrichtung gesteckt und durch das Tauchbad gezogen. Danach wird überschüssiger Kleber bzw. Gemisch aus Kleber und biologisch aktiven Silberionen abgeschleudert. Nun erfolgt die Beflockung des Formkörpers 8 rundum dreidimensional mit den Fasern des Viskose Flocks in einem elektrischen Feld, so dass die Fasern sich in dem elektrischen Feld ausrichten und im Wesentlichen senkrecht zur Oberfläche des Formkörpers stehen. Nach der Beflockung werden überschüssige Fasern abgeblasen und von einer Saugeinrichtung aufgenommen. Es erfolgt dann die Trocknung des mit den Fasern beflockten Formkörpers in unterschiedlichen Temperaturzonen. Für die Dauer der Trocknung sind ca. 15 Minuten vorgesehen. Gegebenenfalls kann danach nochmals ein Ausblasen überschüssiger Fasern erfolgen.For the preparation of the shoe accessory on the example of the shoe trees 1 according to Fig. 1 For example, to produce the solid, the raw materials polyol and isocyanate are first injected into release-treated molds. The ratio of polyol to isocyanate is preferably 3: 1. The reaction of the components takes place under a heating stretch. After curing of the foam material of the molded body 8 thus formed is removed from the mold. The adhesive, in particular a dispersion adhesive, is mixed with the addition of biologically active silver ions and, if a certain color of the flock 4 is desired, with color paste. The proportion of silver ion addition may be between 0.2% and 0.7%, preferably 0.5%. The mixture of the adhesive pretreated in this way is placed in a container and thus forms a dip bath for the molded body 8. The molded body 8 is placed on a receiving device and pulled through the dipping bath. Thereafter, excess adhesive or mixture of adhesive and biologically active silver ions is spun off. Now the flocking of the shaped body 8 is carried out all around three-dimensionally with the fibers of the viscose flock in an electric field, so that the fibers align themselves in the electric field and are substantially perpendicular to the surface of the shaped body. After flocking excess fibers are blown off and absorbed by a suction device. The drying of the shaped body flocked with the fibers then takes place in different temperature zones. For the duration of drying is about 15 minutes. Optionally, a blow-out of excess fibers can then take place again.

Im beschriebenen Ausführungsbeispiel besteht die Beflockung 4 aus Fasern eines Viskose Flocks, wobei die Fasern mit dem Kleber auf den Kontaktbereich 5 des aus Kunststoff bestehenden Formkörpers 8 aufgebracht sind. Es kann zweckmäßig sein, dass der Viskose Flock aus unterschiedlichem Fasermaterial besteht. Zur Unterstützung der antibakteriellen Wirkung kann es auch zweckmäßig sein, geeignete Zusatzstoffe beizusetzen.In the described embodiment, the flocking 4 consists of fibers of a viscose flock, wherein the fibers are applied with the adhesive to the contact region 5 of the molded body 8 consisting of plastic. It may be expedient that the viscose flock consists of different fiber material. In order to support the antibacterial effect, it may also be expedient to add suitable additives.

An der Oberseite der Ringfeder 12 ist ein unterer Griff 15 angeformt, durch den ein Druckstab 13 hindurchgeführt ist. Der Druckstab 13 ist an seinem unteren Ende mit dem unteren Bereich der Ringfeder 12 verbunden und weist an seinem oberen Ende einen oberen Griff 14 auf. Fig. 2 shows a longitudinal sectional view of a variant of the invention, in which the shoe accessory is designed as a boot tensioner 2 for a schematically indicated boot shaft 18. The bootstrap 2 comprises two shaft tensioners 11, which are pressed outward by means of an annular spring 12 in the direction indicated by arrows 17. At the top of the annular spring 12, a lower handle 15 is formed, through which a push rod 13 is passed. The push rod 13 is connected at its lower end to the lower portion of the annular spring 12 and has an upper handle 14 at its upper end.

Zum Einsetzen des Stiefelspanners 2 greifen die Finger einer Hand am unteren Griff 15 an, während der obere Griff 14 gegen die Handfläche abgestützt wird. Hierbei wird der untere Griff 15 in Richtung eines Pfeils 16 zum oberen Griff 14 gezogen. In dessen Folge werden seitliche Bereiche der Ringfeder 12 in Richtung der Pfeile 17 aufeinander zu bewegt. Gleiches gilt für die daran befestigten Schaftspanner 11, deren Abstand sich dabei verringert. In diesem Zustand kann der Stiefelspanner 2 in den Stiefelschaft 18 des Stiefels eingesetzt werden. Nach Loslassen der Griffe 14, 15 drückt die Ringfeder 12 die beiden Schaftspanner 11 entgegen der Pfeile 17 nach außen. Äußere Oberflächen der aus Kunststoff gefertigten Schaftspanner 11 bilden dabei Kontaktbereiche 5, die unter Vorspannung an einer inneren Oberfläche 6 des Stiefelschaftes 18 anliegen.To insert the bootstrap 2, the fingers of one hand on the lower handle 15, while the upper handle 14 is supported against the palm. Here, the lower handle 15 is pulled in the direction of arrow 16 to the upper handle 14. As a result, lateral areas of the annular spring 12 are moved towards each other in the direction of the arrows 17. The same applies to the attached shaft tensioner 11, the distance is reduced thereby. In this condition, the bootstrap 2 can be inserted into the bootleg 18 of the boot. After releasing the handles 14, 15 presses the annular spring 12, the two stem tensioner 11 against the arrows 17 to the outside.
