Abstract

A shoe made of plastics has a steel cap (3) which has cushioning (4) in the upper region in the shoe interior. In the remaining region, the steel cap (3) is surrounded on the inside and the outside by the plastic foam which forms the shaft (1) and the shoe bottom (2) of the shoe made of plastics. The cushioning (4) consists of an air-absorbing material so that the air which is displaced by the plastic under the cap during filling the mould with foam does not lead to bubbles in the plastic. <IMAGE>

Description

Die Erfindung bezieht sich auf einen Kunststoffschuh aus einem in einer Form ausschäumenden Kunststoff, vorzugs­weise Polyurethan, welcher in seinem Zehenbereich eine Stahlkappe aufweist. Weiterhin betrifft die Erfindung ein Verfahren zur Herstellung eines solchen Kunststoff­schuhes, bei welchem der Kunststoff in ein offenes Form­unterteil eingegeben, dann ein Leisten als Formkern ein­gesetzt und danach ein Formoberteil auf das Formunter­teil aufgesetzt wird.The invention relates to a plastic shoe made of a foam-foaming plastic, preferably polyurethane, which has a steel toe in its toe area. Furthermore, the invention relates to a method for producing such a plastic shoe, in which the plastic is inserted into an open lower mold part, then a last is used as the mold core and then an upper mold part is placed on the lower mold part.

Schuhe aus Polyurethan werden beispielsweise im Naßbe­reich von Metzgereien getragen, weil sie im Gegensatz zu Lederschuhen sehr gut zu reinigen und zu desinfizieren sind. Ein in großen Stückzahlen verbreiteter Kunststoff­schuh der vorstehenden Art ist unter der Bezeichnung "Jollys" bekannt. Dieser Schuh wird im Freizeitbereich, insbesondere bei der Gartenarbeit, aber auch in Operati­onssälen von Krankenhäusern und im gewerblichen Bereich getragen.Shoes made of polyurethane are worn in butchers' wet areas, for example, because, unlike leather shoes, they are very easy to clean and disinfect. A large number of plastic shoe of the above type is known under the name "Jollys". This shoe is worn in the leisure area, especially in gardening, but also in operating rooms of hospitals and in the commercial sector.

Für zahlreiche Verwendungsfälle ist es erforderlich, daß der Schuh eine Stahlkappe aufweist. Bei Schuhen mit Stahlkappe wird diese meist in den Schuh eingeklebt. Ein solches Herstellungsverfahren wäre für einen Kunststoff­schuh unerwünscht teuer, da das Einkleben von Stahlkap­pen jeweils einen zusätzlichen, zeitaufwendigen Arbeits­gang erfordern würde. Das Einbringen der Stahlkappe in die Form führt zu Schwierigkeiten, weil sich beim Aus­schäumen der Form Luft im oberen Bereich der Stahlkappe sammelt und deshalb dort kein Kunststoff hingelangt, so daß die Stahlkappe in diesem Bereich ungepolstert ver­ bleibt. Man könnte diesem Mißstand natürlich dadurch begegnen, daß man die Stahlkappe auf ihrer Innenseite vollständig mit einer Auspolsterung versieht. Das hätte jedoch den Nachteil, daß sie nur noch einseitig vom Kunststoff des Schuhes umgeben und deshalb weniger fest im Kunststoff verankert wäre. Bei einem Stoß von vorn könnte die Kappe dann im Schuh nach hinten rutschen.For numerous applications, it is necessary for the shoe to have a steel toe. In the case of shoes with a steel toe cap, this is usually glued into the shoe. Such a manufacturing process would be undesirably expensive for a plastic shoe, since the gluing in of steel caps would require an additional, time-consuming operation. The introduction of the steel cap into the mold leads to difficulties because when the mold is foamed, air collects in the upper area of the steel cap and therefore no plastic can reach it, so that the steel cap is unpadded in this area remains. One could, of course, counter this maladministration by completely padding the steel cap on the inside. However, this would have the disadvantage that it would only be surrounded on one side by the plastic of the shoe and would therefore be less firmly anchored in the plastic. In the event of an impact from the front, the cap could slide backwards in the shoe.

Bei Gummi- und PVC-Stiefeln ist es auch schon bekannt, eine Stahlkappe außenseitig zu umspritzen. Bei der Her­stellung solcher Stiefel wird der Kunststoff jedoch in eine geschlossene Form eingespritzt (injection moul­ding), so daß die vorgenannten Probleme durch Luftein­schlüsse nicht auftreten.In rubber and PVC boots, it is also known to overmold a steel cap on the outside. In the manufacture of such boots, however, the plastic is injected into a closed mold (injection molding), so that the aforementioned problems due to air pockets do not occur.

Der Erfindung liegt die Aufgabe zugrunde, einen Kunst­stoffschuh der eingangs genannten Art so auszubilden, daß seine Stahlkappe auf ihrer Innenseite vollständig mit polsterndem Material umgeben und möglichst fest in der Schuhspitze verankert ist. Weiterhin soll ein Ver­fahren zur Herstellung eines solchen Schuhes entwickelt werden.The invention has for its object to design a plastic shoe of the type mentioned in such a way that its steel toe is completely surrounded on its inside with cushioning material and is anchored as firmly as possible in the toe. Furthermore, a method for producing such a shoe is to be developed.

Die erstgenannte Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Stahlkappe in ihrem oberen Bereich eine luftaufnehmende Aufpolsterung aufweist und im übrigen Bereich in den Kunststoff des Schuhes eingelassen ist.The first-mentioned object is achieved according to the invention in that the steel toe has air-absorbing padding in its upper area and is embedded in the plastic of the shoe in the remaining area.

Durch diese erfindungsgemäße Ausbildung ist die Stahl­kappe des Kunststoffschuhs im unteren Bereich durch die völlige Kunststoffumschließung zuverlässig im Kunststoff des Schuhes verankert. Im sich anschließenden, oberen Bereich hat sie innenseitig die Aufpolsterung, so daß der Fuß nirgends unmittelbar gegen die Stahlkappe ge­langen kann. Die Aufpolsterung nimmt bei der Herstellung des Schuhes vom ausschäumenden Kunststoff im Kappenbe­reich verdrängte Luft auf und leitet sie teilweise nach oben hin ab. Deshalb können Luftblasen nicht das innen­seitige Umschäumen der Stahlkappe mit Kunststoffschaum und damit ihre zuverlässige Verankerung verhindern. Die Aufpolsterung hat somit nicht nur die Funktion, beim fertigen Schuh die Stahlkappe innenseitig zu polstern, vielmehr dient sie bei der Herstellung dazu, Luftblasen­einschlüsse im Kunststoff auszuschließen.With this design according to the invention, the steel toe of the plastic shoe is reliably anchored in the plastic of the shoe in the lower region due to the complete plastic enclosure. In the adjoining upper area, the padding is on the inside, so that the foot cannot come directly against the steel cap anywhere. During the manufacture of the shoe, the padding absorbs air that is displaced by the foaming plastic in the toe area and partially directs it from the top. Therefore, air bubbles cannot prevent the inside of the steel cap from being foamed with plastic foam and thus prevent it from being reliably anchored. The padding therefore not only has the function of cushioning the inside of the steel toe in the finished shoe, but rather serves to exclude air pockets in the plastic during manufacture.

Ohne die erfindungsgemäße Aufpolsterung bestünde beim Ausschäumen die Gefahr, daß Luft gegen Ende des Aus­schäumvorganges aus dem kritischen Bereich unter der Stahlkappe herausgedrückt wird und dann an dem schon anreagierten Kunststoffschaum im Schaftbereich einge­fangen wird, so daß es dort zu Lunkerstellen kommt.Without the upholstery according to the invention, there would be the danger during foaming that air would be pushed out of the critical area under the steel cap towards the end of the foaming process and would then be caught in the already reacted plastic foam in the shaft area, so that there would be voids.

Die zweitgenannte Aufgabe, nämlich die Schaffung eines Verfahrens zur Herstellung des Kunststoffschuhes, wird erfindungsgemäß dadurch gelöst, daß auf der Spitze des Leistens eine Stahlkappe mit geringem Abstand zur Lei­stenoberfläche aufgebracht wird, welche ausschließlich in ihrem oberen Bereich eine luftaufnehmende Auspolste­rung aufweist.The second task, namely the creation of a method for producing the plastic shoe, is achieved according to the invention in that a steel cap is applied to the tip of the last with a small distance from the last surface, which has an air-absorbing padding exclusively in its upper region.

Durch diese Verfahrensweise ist sichergestellt, daß sich im oberen Kappenbereich beim Ausschäumen keine Luftbla­sen sammeln können, wodurch ungepolsterte Kappenbereiche entstehen würden. Weiterhin wird dadurch erreicht, daß die Stahlkappe im unteren Bereich zuverlässig im Kunst­stoff verankert ist.This procedure ensures that no air bubbles can collect in the upper cap area when foaming, which would result in unpadded cap areas. It is also achieved that the steel cap is reliably anchored in the plastic in the lower area.

Bei der Schuhherstellung braucht die Stahlkappe ledig­lich von Hand auf den Leisten aufgelegt zu werden, wenn auf dem Leisten als Abstandshalter für die Stahlkappe Magnete befestigt werden. Diese Magnete vermögen die Stahlkappe beim Ausschäumen ausreichend fest in der Form zu halten, so daß sie nicht verrutscht.In shoe manufacture, the steel toe cap only needs to be placed on the last by hand if magnets are attached to the last as a spacer for the steel toe. These magnets are able to hold the steel cap sufficiently firmly in the mold when it is being foamed so that it does not slip.

Besonders fest ist die Stahlkappe im Kunststoff des Schuhes eingebettet, wenn eine Stahlkappe benutzt wird, welche mit einem umgebördelten Bereich in die Sohle des Kunststoffschuhes ragt.The steel toe is embedded particularly firmly in the plastic of the shoe if a steel toe is used which projects with a flanged area into the sole of the plastic shoe.

Auch die erforderlichen Abstandshalter führen nicht zu Stellen, an denen sich kein Kunststoffschaum oder Auf­polstermaterial befindet, wenn die Abstandshalter aus­schließlich im Bereich der Auspolsterung und des umge­bördelten Bereiches angeordnet werden.The required spacers do not lead to places where there is no plastic foam or padding material if the spacers are arranged exclusively in the area of the padding and the flanged area.

Die Erfindung läßt zahlreiche Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips wird nach­folgend auf die Zeichnung Bezug genommen. Diese zeigt in

  • Fig. 1 einen Längsschnitt durch einen vorderen Be­reich eines erfindungsgemäß gestalteten Kunststoffschuhes,
  • Fig. 2 einen Schnitt durch einen vorderen Bereich einer Form zur Herstellung des Kunststoff­schuhes.
The invention allows numerous embodiments. To further clarify its basic principle, reference is made to the drawing below. This shows in
  • 1 shows a longitudinal section through a front region of a plastic shoe designed according to the invention,
  • Fig. 2 shows a section through a front region of a mold for the production of the plastic shoe.

Bei dem in Figur 1 teilweise gezeigten Kunststoffschuh ist ein Schaft 1 einstückig mit einem Schuhboden 2 aus­gebildet. Im Spitzenbereich des Kunststoffschuhes ist eine Stahlkappe 3 angeordnet. Diese begrenzt in ihrem oberen Bereich mit einer innenseitigen Aufpolsterung 4 aus einem luftaufnehmenden Polstermaterial den Schuh­innenraum. Im unteren Bereich ist die Stahlkappe 3 in den Kunststoffschaum des Schaftes 1 und des Schuhbodens 2 eingelassen. Innerhalb des Schuhbodens 2 hat die Stahl­kappe 3 eine sich horizontal erstreckende Umbördelung 5, die die Verankerung der Stahlkappe 3 zusätzlich verbes­sert. Innerhalb des Kunststoffschuhes befindet sich ein aus ihm herausnehmbares Fußbett 6 aus Kork-Latex.In the plastic shoe partially shown in FIG. 1, a shaft 1 is formed in one piece with a shoe bottom 2. A steel cap 3 is arranged in the tip area of the plastic shoe. In its upper area, this delimits the interior of the shoe with an internal padding 4 made of an air-absorbing cushioning material. In the lower area, the steel cap 3 is embedded in the plastic foam of the upper 1 and the shoe bottom 2. Within the shoe bottom 2, the steel toe 3 has a horizontally extending flange 5, which additionally improves the anchoring of the steel toe 3. Inside the plastic shoe is a removable footbed 6 made of cork latex.

Die Figur 2 zeigt einen vorderen Bereich eines horizon­tal ausgerichteten Formunterteils 7, welches nach oben hin von einem Formoberteil 8 abgedeckt ist. Innerhalb der durch das Formunterteil 7 und Formoberteil 8 gebil­deten Form befindet sich als Formkern ein Leisten 9. Dieser hat auf seiner Spitze nach oben gerichtete Ab­standshalter 10, 11, bei dem es sich jeweils um einen Magneten handelt. An der Unterseite des Leistens 9 sind weitere Abstandshalter 12 in Form von nach unten gerich­teten Stiften vorgesehen. Diese Abstandshalter 10, 11, 12 positionieren die Stahlkappe 3 auf dem Leisten 9, so daß diese in ihrem oberen Bereich mit der Aufpolsterung 4 gegen den Leisten 9 anliegt, im übrigen jedoch überall geringen Abstand von ihm hat.FIG. 2 shows a front area of a horizontally oriented lower mold part 7, which is covered at the top by an upper mold part 8. Within the mold formed by the lower mold part 7 and upper mold part 8 there is a strip 9 as the mold core. This has spacers 10, 11, which are directed upwards at their tips, each of which is a magnet. Further spacers 12 in the form of downward-pointing pins are provided on the underside of the strip 9. These spacers 10, 11, 12 position the steel cap 3 on the last 9, so that it rests in its upper region with the padding 4 against the last 9, but is otherwise everywhere at a short distance from it.

Bei der Herstellung des Kunststoffschuhes gibt man zu­nächst in das offene Formunterteil 7 Polyurethan ein. Dann schwenkt man den mit der Stahlkappe 3 versehenen Leisten in das Formunterteil 7 und schließt anschließend die Form dadurch, daß das Formoberteil 8 auf das Form­unterteil 7 geschwenkt wird. Der ausschäumende Kunst­stoff umgibt den unteren Bereich der Stahlkappe 3 voll­ständig. Die dabei verdrängte Luft wird von der Auf­polsterung 4 aufgenommen und teilweise nach oben hin abgeleitet.In the manufacture of the plastic shoe, one first enters 7 polyurethane into the open lower mold part. Then you swivel the strips provided with the steel cap 3 into the lower mold part 7 and then close the mold in that the upper mold part 8 is pivoted onto the lower mold part 7. The foaming plastic completely surrounds the lower area of the steel cap 3. The air displaced in the process is absorbed by the padding 4 and partially discharged upwards.
