To this end, a safety feature is provided that instructs to the wearer of the item of protective footwear to replace the shoe when a certain minimum profile depth is reached.

Description

Sicherheitsschuh und Profilsohle für denselben Safety shoe and profile sole for the same
Die vorliegende Erfindung betrifft einen Sicherheitsschuh mit einer Profilsohle, ferner eine Profilsohle für einen derartigen Schuh.The present invention relates to a safety shoe with a tread sole, also a tread sole for such a shoe.
Sicherheitsschuhe werden von bestimmten Personen benötigt, deren Tätigkeit einen entsprechenden Schutz ihrer Füße erfordert. Darüber hinaus sollen derartige Sicherheitsschuhe für eine verbesserte Standfestigkeit mit rutschhemmender Eigenschaft der sie tragenden Person sorgen. Sie sind daher mit entsprechenden Sicherheitsmerkmalen, wie Stahlkappen, Profilsohlen etc., ausgestattet .Safety shoes are required by certain people whose work requires appropriate protection of their feet. In addition, such safety shoes are intended to provide improved stability with a non-slip property of the person wearing them. They are therefore equipped with appropriate safety features such as steel caps, profile soles, etc.
Ein wesentlicher Bestandteil von derartigen Sicherheits- schuhe sind geeignete Profilsohlen, um einer Rutschgefahr vorzubeugen. Diese Profilsohlen erfüllen ihre Auf- gäbe im neuen Zustand, werden jedoch im Laufe der Zeit, je nach den vorherrschenden Bedingungen, immer mehr abgenutzt, so daß letztendlich ein gefahrlicher Zustand entsteht, indem die erforderliche Sicherheit gegenüber Rutschen nicht mehr erreicht wird. Wird dieser Zustand erreicht, sind die Sicherheitsschuhe nicht mehr verwendbar, da bei modernen Schuhen das Erneuern der Sohle bzw. Anbringen einer neuen Sohle nicht mehr in Frage kommt. In der Praxis wird jedoch in der Regel der geeignete Zeitpunkt zum Austausch der Schuhe verpaßt, sei es aus Unachtsamkeit, aus Kostengründen etc., so daß Sicherheitsschuhe mit abgenutzten Profilen getragen werden, die die erforderlich Rutschsicherheit nicht mehr bieten.Appropriate profile soles are an essential part of such safety shoes to prevent slipping. These profile soles fulfill their would exist in the new state, but will wear out more and more over time, depending on the prevailing conditions, so that ultimately a dangerous state arises in that the required safety against slipping is no longer achieved. If this condition is reached, the safety shoes can no longer be used, since modern shoes can no longer be replaced or a new sole attached. In practice, however, the appropriate time to replace the shoes is usually missed, be it due to carelessness, for cost reasons, etc., so that safety shoes with worn profiles that no longer offer the required slip resistance are worn.
Ähnlich wie bei Autoreifen ist daher eine bestimmte minimale Profiltiefe erforderlich, um für die erforderliche Bodenhaftung zu sorgen.Similar to car tires, a certain minimum tread depth is therefore required to ensure the necessary traction.
Die vorliegende Erfindung will der vorstehend geschil- derten Problematik abhelfen. Ihr liegt die Aufgabe zugrunde, einen Sicherheitsschuh zu schaffen, der ein Sicherheitsmerkmal aufweist, das anzeigt, wenn die erforderliche Mindestprofiltiefe erreicht wird, ferner eine Profilsohle für einen derartigen Schuh.The present invention intends to remedy the problem described above. It is the object of the invention to create a safety shoe which has a safety feature which indicates when the required minimum tread depth has been reached, and also a tread sole for such a shoe.
Diese Aufgabe wird erfindungsgemäß bei einem Sicherheitsschuh mit einer Profilsohle dadurch gelöst, daß die Profilsohle mindestens einen optisch vom restlichen Teil der Profilsohle unterscheidbaren Abschnitt aufweist, der bei einer bestimmten Abnutzung des Profils erkennbar wird. Die Erfindung sieht daher ein Sicherheitsmerkmal vor, das den Benutzer des Sicherheitsschuhs mit zunehmender Abnutzung des Profils der Sohle darauf aufmerksam macht, wenn die gerade noch ausreichende Rutschsicherheit bietende Mindestprofiltiefe erreicht ist und ein weiteres Tragen des Schuhs gefährlich wird. Der Benutzer muß daher nicht mehr die Profiltiefe abschätzen bzw. genau abmessen, um den Zeitpunkt ermitteln zu können, an dem die Schuhe nicht mehr verwendbar sind. Hinzu kommt, daß der Benutzer in den meisten Fällen überhaupt nicht weiß, welche Profiltiefe noch ausreichende Sicherheit bietet, so daß die erfindungsgemäße Lösung auch diesem Problem abhilft und beim Sichtbarwerden des optisch vom restli- chen Teil der Profilsohle unterscheidbaren Abschnitts deutlich macht, daß nunmehr ein Austausch des Schuhs angebracht ist.This object is achieved according to the invention in a safety shoe with a tread sole in that the tread sole has at least one section which is optically distinguishable from the rest of the tread sole and which is recognizable when the tread is worn to a certain extent. The invention therefore provides a safety feature that notifies the user of the safety shoe as the profile of the sole becomes increasingly worn when the minimum tread depth that is still sufficient to provide slip resistance is reached and further wearing of the shoe becomes dangerous. The user therefore no longer has to estimate or precisely measure the tread depth in order to be able to determine the point in time at which the shoes can no longer be used. In addition, in most cases the user does not know at all which tread depth still offers sufficient security, so that the solution according to the invention also remedies this problem and, when the section which is optically distinguishable from the rest of the tread base becomes visible, makes it clear that a Replacing the shoe is appropriate.
Der erfindungsgemäß vorgesehene Abschnitt sollte sich optisch deutlich vom restlichen Teil der Profilsohle unterscheiden, beispielsweise eine rote Farbe besitzen, so daß bei den in der Regel dunkel eingefärbten Profilsohlen von Sicherheitsschuhen ein deutlich erkennbares Sicherheitsmerkmal gegeben ist. Dies schließt natürlich nicht aus, daß erfindungsgemäß auch andersfarbige Abschnitte verwendet werden können. Wesentlich ist, daß ein ausreichender Kontrast zum restlichen Teil der Profilsohle gegeben ist.The section provided according to the invention should differ visually from the rest of the profile sole, for example have a red color, so that the generally dark colored profile soles of safety shoes have a clearly recognizable safety feature. Of course, this does not exclude that differently colored sections can also be used according to the invention. It is essential that there is sufficient contrast to the rest of the profile sole.
Der erfindungsgemäß vorgesehene Abschnitt ist im ungebrauchten Zustand des Sicherheitsschuhs und im Zustand der zulassigen Profilabnutzung nicht erkennbar. Der Trager des Schuhs weiß damit, daß die Profilsohle noch ausreichende Rutschsicherheit bietet. Wird der erfmdungsgemaß vorgesehene Abschnitt mit zunehmender Abnutzung des Profils freigelegt, ist der Zeitpunkt erreicht, an dem ein Austausch des Schuhs erforderlich ist.The section provided according to the invention is in the unused state of the safety shoe and in the state the permissible profile wear is not recognizable. The wearer of the shoe knows that the tread sole still offers sufficient slip resistance. If the section provided according to the invention is exposed with increasing wear of the profile, the point in time at which an exchange of the shoe is necessary is reached.
Der erfmdungsgemaß vorgesehene Abschnitt ist vorzugsweise in das Profil der Sohle eingearbeitet. Er ist zweckmaßigerweise vollständig von einem Profilabschnitt bzw. einer Profilleiste ummantelt, so daß sich auch eine seitliche Abdeckung des Abschnittes ergibt.The section provided according to the invention is preferably incorporated into the profile of the sole. It is expediently completely encased by a profile section or a profile strip, so that there is also a lateral covering of the section.
Bei einer besonders bevorzugten Ausfuhrungsform besteht der erf dungsgemaße Abschnitt aus einem anderen Material als die restliche Profilsohle. Dieser Abschnitt aus anderem Material wird vorzugsweise beim Herstellen der Sohle in diese emgeschäumt, so daß sich ein inniger Verbund mit dem restlichen Sohlenmaterial ergibt und im wesentlichen keine Inhomogenitäten in der Sohle auftreten, die diese durchlassig machen oder den Tragekomfort des Schuhs reduzieren konnten. Ein besonders geeignetes Material für den erf dungsgemaß vorgesehenen Abschnitt ist Polyurethan aber auch Nitrilbutadienkautschuk oder TPU (thermoplastisches Polyurethan).In a particularly preferred embodiment, the section according to the invention consists of a different material than the rest of the profile sole. This section of other material is preferably foamed into the sole during manufacture, so that there is an intimate bond with the remaining sole material and essentially no inhomogeneities occur in the sole, which could make it permeable or reduce the comfort of the shoe. A particularly suitable material for the section provided according to the invention is polyurethane, but also nitrile butadiene rubber or TPU (thermoplastic polyurethane).
Es versteht sich, daß die vorstehend beschriebenen Pro- filsohlen m der Regel nicht gleichmäßig abgenutzt werden, j e nach Verwendungsart und Gangart sowie Abrollbe- wegung des Fußes. So sind beispielsweise der Vorderbereich und Absatzbereich der Sohle besonders starken Ab- nutzungen ausgesetzt, wahrend der mittlere Sohlenbereich relativ lange ein intaktes Profil tragt. Um diesen unterschiedlichen Abnutzungsmoglichkeiten gerecht zu werden, sieht die Erfindung vor, daß die Profilsohle mehre- re optisch vom restlichen Teil der Sohle unterscheidbare Abschnitte aufweist, so daß auch bei einer örtlich begrenzten Abnutzung der Profilsohle dafür Sorge getragen wird, daß eine das zulassige Maß überschreitende Abnutzung angezeigt wird. Die erf dungsgemaß vorgesehenen Abschnitte sind daher vorzugsweise an mehreren Stellen über die Sohle verteilt angeordnet, so daß insbesondere die kritischen Abnutzungsbereiche erfaßt werden.It goes without saying that the profile soles described above are generally not worn evenly, depending on the type of use and the gait as well as the rolling motion of the foot. For example, the front area and heel area of the sole are particularly strong exposed to uses, while the middle sole area has an intact profile for a relatively long time. In order to do justice to these different possibilities of wear, the invention provides that the profiled sole has several sections which can be distinguished optically from the remaining part of the sole, so that even if the profiled sole is worn locally, care is taken to ensure that one which exceeds the permissible dimension Wear appears. The sections provided according to the invention are therefore preferably distributed over the sole at several points, so that in particular the critical areas of wear are detected.
Es ist daher zweckmäßig, insbesondere im Spitzenbereich der Sohle und im Fersenbereich derselben mindestens einen erfmdungsgemaßen Abschnitt vorzusehen.It is therefore expedient to provide at least one section according to the invention, in particular in the tip region of the sole and in the heel region thereof.
Die Lage des erf dungsgemaßen Abschnittes in Tiefenrichtung der Sohle richtet sich nach dem zulassigen Ab- nutzungsbereich des Profils. Wesentlich ist, daß der Abschnitt mit seiner Unterseite so angeordnet ist, daß bei seiner Freilegung, d.h. Abnutzung des darunter befindlichen Sohlenmaterials, die minimal zulassige Profiltiefe erreicht ist. Die entsprechenden Tiefenwerte können von Anwendungsfall zu Anwendungsfall variieren, so daß hier auf die Angabe von Zahlenwerten verzichtet wird.The position of the section according to the invention in the depth direction of the sole depends on the permissible area of wear of the profile. It is essential that the section is arranged with its underside so that when it is exposed, i. Wear of the sole material underneath, the minimum permissible tread depth has been reached. The corresponding depth values can vary from application to application, so that numerical values are not given here.
Die vorstehende Aufgabe wird ferner durch eine Profilsohle für einen derartigen Schuh gelost. Die Erfindung wird nachfolgend anhand eines Ausfuhrungs- beispiels in Verbindung mit der Zeichnung im einzelnen erläutert. Es zeigen:The above object is also achieved by a profile sole for such a shoe. The invention is explained in detail below using an exemplary embodiment in conjunction with the drawing. Show it:
Figur 1 eine Seitenansicht eines Sicherheitsschuhs mit Profilsohle; undFigure 1 is a side view of a safety shoe with a tread sole; and
Figur 2 einen mittigen Vertikalschnitt durch denFigure 2 is a central vertical section through the
Absatzbereich des in Figur 1 dargestellten Sicherheitsschuhs .Sales area of the safety shoe shown in Figure 1.
Der in Figur 1 gezeigte Sicherheitsschuh 1 ist nur schematisch dargestellt. Der Schuh besitzt einen Schaft 2 und eine unter diesem angeordnete Profilsohle 3, die ei- ne Vielzahl von einzelnen Profllabschnitten bzw. Profil- leisten 4 aufweist, wobei diese Profilleisten 4 auf der Unterseite der Profilleiste unterschiedlich ausgebildet sind. So sind an der Spitze des Schuhs breitere Leisten vorgesehen als im mittleren Bereich. Ferner weist auch der Absatzbereich breitere Leisten auf. Die Ausgestaltung der Profllleisten ist von Schuh zu Schuh unterschiedlich und hier nicht Gegenstand der Erfindung.The safety shoe 1 shown in FIG. 1 is only shown schematically. The shoe has a shaft 2 and a profile sole 3 arranged underneath it, which has a multiplicity of individual profile sections or profile strips 4, these profile strips 4 being designed differently on the underside of the profile strip. For example, wider lasts are provided at the tip of the shoe than in the middle. Furthermore, the sales area also has wider strips. The design of the profile strips varies from shoe to shoe and is not the subject of the invention here.
In das Profil der Profilsohle 3 sind an mehreren Stellen (in Figur 1 sind nur 3 Stellen beispielsweise gezeigt)In the profile of the profile sole 3 are in several places (only 3 places are shown in Figure 1, for example)
Abschnitte 5 eingearbeitet, die sich optisch vom restlichen Teil der Profilsohle 3 unterscheiden. Im vorliegenden Ausfuhrungsbeispiel besitzen diese Abschnitte 5 eine rote Farbe, wahrend die übrige Profilleiste dunkel ein- gefärbt ist. Die Abschnitte 5 sind so in die Profilsohle eingearbeitet, daß sie etwas in die jeweiligen Profil- leisten und nach unten vorstehen, wie dies in Figur 1 gezeigt ist. Nach entsprechender Abnutzung der Profilleisten wird daher die Unterseite der Abschnitte 5 freigelegt und ist erkennbar.Sections 5 incorporated, which differ optically from the rest of the profile sole 3. In the present exemplary embodiment, these sections 5 have a red color, while the remaining profile strip is colored dark. The sections 5 are worked into the profile sole in such a way that they fit somewhat into the respective profile afford and protrude downward, as shown in Figure 1. After appropriate wear of the profile strips, the underside of the sections 5 is therefore exposed and can be seen.
Bei diesen Abschnitten 5 handelt es sich um ein in den Sicherheitsschuh eingebautes Sicherheitsmerkmai, das anzeigt, wenn eine Mmdestproflltiefe erreicht ist, unter der, ahnlich wie bei einem Autoreifen, eine weitere Nut- zung des Schuhs nicht mehr angebracht bzw. kritisch ist.These sections 5 are a safety feature built into the safety shoe, which indicates when a minimum test depth has been reached below which, similar to a car tire, further use of the shoe is no longer appropriate or critical.
Einzelheiten diese Sicherheitsmerkmais sind in der vergrößerten Darstellung von Figur 2 gezeigt, die ein Vertikalschnitt durch den Absatzbereich des in Figur 1 ge- zeigten Sicherheitsschuhs ist. Man erkennt, daß jedeDetails of this safety feature are shown in the enlarged illustration in FIG. 2, which is a vertical section through the heel area of the safety shoe shown in FIG. 1. You can see that everyone
Profilleiste 4 des Absatzbereiches einen eingearbeiteten Abschnitt 5 aufweist, der sich farblich vom übrigen Teil der Profilsohle abhebt. Der Abschnitt 5 ist vollständig von einer Profilleiste ummantelt und in bezug auf die Unterseite der Profilleiste 4 so angeordnet, daß seine Unterseite der maximal zulassigen Abnutzung der Profilleiste entspricht. Diese maximal zulassige Abnutzung ist in Figur 2 durch eine gestrichelte Linie 6 angedeutet. Wird die Profilleiste 4 durch Tragen des Schuhs bis zu dieser Linie 6 abgenutzt, wird die Unterseite des andersfarbigen Abschnittes 5 freigegeben, so daß der Trager des Schuhs erkennt, das der Schuh ausgewechselt werden muß .Profile strip 4 of the heel area has an incorporated section 5, which is different in color from the rest of the profile sole. The section 5 is completely encased by a profile strip and arranged with respect to the underside of the profile strip 4 so that its underside corresponds to the maximum permissible wear of the profile strip. This maximum permissible wear is indicated in FIG. 2 by a dashed line 6. If the profile strip 4 is worn by wearing the shoe up to this line 6, the underside of the differently colored section 5 is released so that the wearer of the shoe recognizes that the shoe must be replaced.
Je nach Ausfuhrungsform kann jede Profilleiste 4 der Profilsohle 3 des Schuhs einen derartigen Abschnitt 5 aufweisen, oder es können nur einige Abschnitte 5 in Profilleisten vorgesehen sein, die einer besonders starken Abnutzung ausgesetzt sind. Das Material der Abschnitte 5 kann dem Material der Profilsohle 3 entspre- chen oder aus einem anderen Material bestehen. Wichtig ist, daß eine gute Einbindung der Abschnitte 5 in die Profilsohle 3 erfolgt.Depending on the embodiment, each profile strip 4 of the profile sole 3 of the shoe can have such a section 5 have, or only some sections 5 can be provided in profile strips that are exposed to particularly heavy wear. The material of the sections 5 can correspond to the material of the profile sole 3 or consist of another material. It is important that the sections 5 are well integrated into the profile sole 3.
Zur Herstellung des dargestellten Sicherheitsschuhs wird die mit dem Sicherheitsmerkmal versehene Profilsohle (Laufsohle) mit dem Schaft verschaumt, verklebt oder vernäht . To produce the safety shoe shown, the profile sole (outsole) provided with the safety feature is foamed, glued or sewn to the shaft.
