Abstract
Description
Die Erfindung richtet sich auf einen Schutzschuh, Sicherheitsschuh bzw. ―stiefel mit einer Zehenkappe aus Kunststoff, insbesondere einen Arbeitsschutzschuh.The invention is directed to a protective shoe, safety shoe or ― Boots with a plastic toe cap, in particular a work safety shoe.
Die Zehenkappen für derartige Schuhe wurden herkömmlicherweise aus Stahl gefertigt. Mit diesem Material läßt sich zwar eine hohe Festigkeit erreichen, jedoch ist das Gewicht relativ hoch und die gute Wärmeleitfähigkeit fördert ein Kälteempfinden im Zehenbereich beim Tragen des Schuhs.The toe caps for such shoes have traditionally been made from Made of steel. A high level of strength can be achieved with this material, however, the weight is relatively high and the good thermal conductivity promotes a feeling of cold in the toe area when wearing the shoe.
Man hat deshalb zur Vermeidung dieser Nachteile und zur Erzielung einer kostengünstigen Herstellbarkeit Zehenkappen aus Kunststoff entwickelt, wie sie beispielsweise in WO 98/48999 beschrieben werden.One therefore has to avoid these disadvantages and to achieve one inexpensive manufacturability developed toe caps made of plastic, as described for example in WO 98/48999.
Zur Erzielung einer hinreichenden Festigkeit, wie sie von den Normen gefordert wird, z.B. einer Stoßfestigkeit von mindestens 200 J und einer Widerstandsfähigkeit von 15 KN, wurden herkömmlicherweise verwendete Kunststoffe mit Glasfasern oder anderen Materialien verstärkt.To achieve sufficient strength, as required by the standards e.g. a shock resistance of at least 200 J and one Resistance of 15 KN has been used conventionally Reinforced plastics with glass fibers or other materials.
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, insbesondere Arbeitsschutzschuhe mit einer Zehenkappe aus Kunststoff so weiterzuentwickeln, daß bei kostengünstiger Herstellbarkeit ein die Normanforderungen übersteigendes hohes Maß an Sicherheit bei großem Tragekomfort erzielt wird. Proceeding from this, the invention is based on the object, in particular To further develop work safety shoes with a plastic toe cap that with inexpensive manufacturability a the standard requirements Exceeding high level of security with great comfort is achieved.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Zehenkappe an der Innenseite im Bereich der Mittel-Längs-Ebene einen Verstärkungssteg aufweist. Es wurde gefunden, daß das Vorsehen eines derartigen Steges an dieser Stelle zu einer erheblichen Festigkeitserhöhung führt, ohne daß die Dicke der Zehenkappe insgesamt erhöht werden müßte. Hierdurch wird also Material und Gewicht gespart.This object is achieved in that the toe cap on the inside in the area of the median longitudinal plane a reinforcement bar having. It has been found that the provision of such a web at this point leads to a significant increase in strength without that the thickness of the toe cap should be increased overall. hereby material and weight are saved.
Gleichzeitig ist es möglich, seitlich des Verstärkungssteges eines anatomische Ausformung für die große Zehe auszubilden, die einen erheblichen Tragekomfort ermöglicht. Es ist zwar an sich bekannt, Kunststoffzehenkappen asymmetrisch derart auszubilden, daß sie im Bereich der großen Zehe eine größere Ausdehnung in Längsrichtung aufweisen als im Bereich der kleinen Zehe. Demgegenüber trägt die vorgesehene anatomische Ausformung für die große Zehe allein dem Umstand Rechnung, daß diese Zehe nicht nur länger, sondern auch breiter ist als die anderen Zehen.At the same time, it is possible to side of the reinforcement web of an anatomical Form for the big toe, which is a significant one Comfortable. It is known per se, plastic toe caps to be designed asymmetrically in such a way that Toe have a greater length in the longitudinal direction than in the area the little toe. In contrast, the intended anatomical shape bears for the big toe only the fact that this toe not only longer, but also wider than the other toes.
Weiterhin kann zur Erhöhung der Festigkeit vorgesehen sein, daß wenigstens längs des Mittelbereiches der Unterkante der Zehenkappe ein Verstärkungssteg verläuft.Furthermore, to increase the strength, it can be provided that at least along the middle area of the lower edge of the toe cap, a reinforcing bar runs.
Als optimales Kunststoffmaterial für die Zehenkappe wird ein Polycarbonatblend, insbesondere ein PC/PBT-Blend verwendet.The optimal plastic material for the toe cap is a polycarbonate blend, especially a PC / PBT blend used.
Nachfolgend wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung näher erläutert. Dabei zeigen:

- eine perspektivische Ansicht der Zehenkappe eines erfindungsgemäßen Schuhs von innen und
- Fig. 2

Eine in der Zeichnung dargestellte Zehenkappe 1 ist aus Kunststoff einstückig gespritzt. Sie besteht aus einem PC/PBT-Blend.A toe cap 1 shown in the drawing is made in one piece from plastic injected. It consists of a PC / PBT blend.
Die dargestellte Zehenkappe 1 ist für den linken Fuß bestimmt, weshalb in
an sich bekannter Weise die Form asymmetrisch derart gestaltet ist, daß die
Zehenkappe 1 im Bereich rechts der Mittel-Längs-Ebene 2 weiter nach
vorne steht. Dabei ist im Rahmen der Erfindung vorgesehen, daß die anatomische
Anpassung sich nicht auf diese an sich bekannte Ausgestaltung
beschränkt, sondern daß darüber hinaus der Bereich der großen Zehe nach
vorne vorspringend eine anatomische Ausformung 3 aufweist, wie dies in
Fig. 2 erkennbar ist.The toe cap 1 shown is intended for the left foot, which is why in
in a known manner, the shape is designed asymmetrically such that the
Toe cap 1 continues in the area to the right of the central
Im Bereich der Unterkante 4 verläuft in der Ebene der Schuhsohle ein Ansatz
5, wobei sich oberhalb der Unterkante 4 ein Verstärkungssteg 6 horizontal
erstreckt, der im Bereich der Mittel-Längs-Ebene 2 in einen mittigen
vertikalen Verstärkungssteg 7 mündet.In the area of the lower edge 4, a shoulder runs in the plane of the
Dieser Verstärkungssteg 7 ermöglicht die Erzielung einer die Normanforderungen
übersteigenden Stoß- und Druckfestigkeit. Beispielsweise wurde für
die Druckfestigkeit 15 KN eine Resthöhe von 21 mm nach zwei Tagen RD-Lagerung
ermittelt. Gleichzeitig wird beiderseits des Steges Material gespart,
was sowohl eine Reduzierung der Materialkosten als auch des Endgewichts
ermöglicht. Zudem ist die Realisierung der anatomischen Ausformung
3 für die große Zehe möglich, die den Tragekomfort wesentlich
erhöht.This reinforcing web 7 enables the standard requirements to be achieved
exceeding shock and pressure resistance. For example, for
the compressive strength 15 KN a residual height of 21 mm after two days of RD storage
determined. At the same time, material is saved on both sides of the web,
which is a reduction both in material costs and in the final weight
allows. In addition, the realization of the
