Description
Die Erfindung richtet sich auf einen Schutzschuh, Sicherheitsschuh bzw. -stiefel mit einer Zehenkappe aus Kunststoff, insbesondere einen Arbeitsschutzschuh, gemäß dem Oberbegriff des Patentanspruchs. Ein solcher Schuh ist bekannt aus FR-A-2 525 443.The invention is directed to a protective shoe, safety shoe or boot with a plastic toe cap, in particular a safety shoe, according to the preamble of the claim. Such a Shoe is known from FR-A-2 525 443.
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 Made of steel. Although this material can be a high strength However, the weight is relatively high and the good thermal conductivity Promotes a feeling of cold in the toe area while 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.It has therefore to avoid these disadvantages and to achieve a cost-effective manufacturability 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 a sufficient strength, as required by the standards is, e.g. a shock resistance of at least 200 J and one Resistance of 15 KN, have 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. On this basis, the invention is based on the object, in particular Safety shoes with a toe cap made of plastic to develop that at cost manufacturability one the standard requirements exceedingly high level of safety with great wearing comfort is achieved.
Diese Aufgabe wird erfindungsgemäß gelöst gemäß dem kennzeichnenden Teil des Patentanspruchs.This object is achieved according to the characterizing Part of the claim.
Eine derartige Zehenkappe ermöglicht es, seitlich des Verstärkungssteges eines anatomische Ausformung für die große Zehe auszubilden, die einen erheblichen Tragekomfort bietet. Es ist zwar an sich bekannt (vgl. FR-A-2 525 443), 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.Such a toe cap makes it possible to laterally of the reinforcing web form an anatomical shape for the big toe, the one offers considerable comfort. It is known per se (cf. FR-A-2 525 443), plastic toe caps asymmetric in such a way, that in the area of the big toe a greater extent in Longitudinal than in the area of the small toe. In contrast, carries the intended anatomical shape for the big toe alone account for the fact that this toe not only longer, but also wider than the other toes.
Weiterhin ist zur Erhöhung der Festigkeit vorgesehen sein, daß wenigstens längs des Mittelbereiches der Unterkante der Zehenkappe ein Verstärkungssteg verläuft.Furthermore, it should be provided to increase the strength that at least along the central region of the lower edge of the toe cap a reinforcing web runs.
