Abstract

Bei einem Schutzschuh, Sicherheitsschuh bzw. -stiefel mit einer Zehenkappe aus Kunststoff, insbesondere einem Arbeitsschutzschuh, ist vorgesehen, dass die Zehenkappe aus einem Polycarbonatblend, insbesondere einem PC/PBT-Blend, besteht.In the case of a protective shoe, safety shoe or boot with a plastic toe cap, in particular a protective work shoe, it is provided that the toe cap consists of a polycarbonate blend, in particular a PC / PBT blend.

Description

Die Erfindung richtet sich auf einen Schutzschuh, Sicherheitsschuh bzw. -stiefel mit einer Zehenkappe aus Kunststoff, insbesondere einen Arbeits­ schutzschuh.The invention is directed to a protective shoe, safety shoe or -boots with a plastic toe cap, especially a work protection shoe.

Derartige Zehenkappen für Schuhe sind bekannt aus WO 98/48999. Wie dort ausgeführt wird, gibt es bereits Zehenkappen aus thermoplastischem Kunstharz verstärkt durch synthetische, anorganische Fasern (EP-A 0 528 249), aus thermisch härtbarem Harz (GB-A 2 050 144), aus einer thermoplastischen Matrix mit Glasfasern (EP-A 0 614 623) sowie Kappen hergestellt durch Spritzgießen aus Polycarbonat (FR-A 2 525 443), aus Po­ lypropylen oder Polyurethan (EP-A 0 617 582), aus Polyamid (FR-A 2 572 259), aus ABS (GB-A 1 284 736) sowie aus unidirektionalen Fasern in einer thermoplastischen Matrix (EP-A 0 100 181). Weiterhin sind Ze­ henkappen bekannt geworden, die eine Sandwichstruktur aufweisen (US-A 5,560,985).Such toe caps for shoes are known from WO 98/48999. How there is already a thermoplastic toe cap Synthetic resin reinforced by synthetic, inorganic fibers (EP-A 0 528 249), from thermally curable resin (GB-A 2 050 144), from one thermoplastic matrix with glass fibers (EP-A 0 614 623) and caps made by injection molding from polycarbonate (FR-A 2 525 443), from Po lypropylene or polyurethane (EP-A 0 617 582), made of polyamide (FR-A 2 572 259), made of ABS (GB-A 1 284 736) and unidirectional fibers in a thermoplastic matrix (EP-A 0 100 181). Furthermore, Ze Henkappen become known, which have a sandwich structure (US-A 5,560,985).

An derartige Zehenkappen werden von den verschiedenen Normen Anfor­ derungen hinsichtlich deren Festigkeit gestellt, beispielsweise eine Stoßfes­ tigkeit von mindestens 200 J und eine Widerstandsfähigkeit von 15 KN.Such toe caps are required by the various standards changes in terms of their strength, such as a shock resistance activity of at least 200 J and a resistance of 15 KN.

Der Erfindung liegt hiervon ausgehend die Aufgabe zugrunde, einen Schutzschuh, Sicherheitsschuh bzw. -stiefel mit einer Kunststoff- Zehenkappe zu schaffen, der mindestens den Normanforderungen gerecht wird, diese bei kostengünstiger Herstellbarkeit aber noch übertreffen soll. Proceeding from this, the object of the invention is one Protective shoe, safety shoe or boot with a plastic To create toe cap that at least meets the standard requirements is, but should still surpass this with inexpensive manufacturability.  

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß als Kunststoff für die Zehenkappe ein Polycarbonatblend verwendet wird.This object is achieved in that as a plastic a polycarbonate blend is used for the toe cap.

Vorzugsweise werden PC/ABS-Blends, PC/TPU-Blends und PC/PBT- oder PC/PET-Blends eingesetzt.PC / ABS blends, PC / TPU blends and PC / PBT or are preferred PC / PET blends used.

Besonders günstig ist die Verwendung eines PC/PBT-Blends. Das letztge­ nannte Blend wurde für Rasenmäher- und Motorsägenteile eingesetzt. Überraschenderweise wurde gefunden, daß bei Verwendung dieses Materials für eine Zehenkappe folgende Eigenschaften erzielt werden konnten:The use of a PC / PBT blend is particularly favorable. The last called blend was used for lawn mower and chain saw parts. Surprisingly it was found that using this material the following properties could be achieved for a toe cap:

Erfindungsgemäße Zehenkappen entsprechen den Anforderungen an Stoß- und Druckfestigkeit nach DIN EN 12568 sowie nach DIN EN 12568 hin­ sichtlicher thermischer und chemischer Alterung.Toe caps according to the invention meet the requirements for impact and compressive strength according to DIN EN 12568 and DIN EN 12568 visible thermal and chemical aging.

Bei einer Stoßeinwirkung von 200 J wurden folgende Werte erzielt:
The following values were achieved with an impact of 200 J:

In keinem Fall trat ein Materialbruch auf. In no case did material breakage occur.  

Bei Messung der Druckfestigkeit 15 KN wurde eine Resthöhe von 21 mm nach zwei Tagen RT-Lagerung ermittelt.When measuring the compressive strength 15 KN, a residual height of 21 mm determined after two days of RT storage.
