Ein derartiger Schutzhandschuh ist aus der
Derzeit bestehen intensive Bestrebungen, verstärkt elektrische Energie anstelle von fossilen Brennstoffen zu nutzen. So sind in den vergangenen Jahren zunehmend Photovoltaiksysteme, beispielsweise auf Gebäudedächern, aufgebaut worden. Außerdem soll in Zukunft individuell Mobilität verstärkt durch elektrische Antriebssysteme, beispielsweise durch Elektrofahrzeuge, ermöglicht werden.Intensive efforts are currently being made to increase the use of electrical energy instead of fossil fuels. In recent years, for example, photovoltaic systems, for example on building roofs, have increasingly been set up. In addition, individual mobility will be made possible in the future by electric drive systems, for example by electric vehicles.
Bislang wird jedoch nur wenig beachtet, dass mit einer derart verstärkten Nutzung elektrischer Energie auch erhebliche Gefahrenpotenziale verbunden sind.So far, however, little attention has been paid to the fact that such increased use of electrical energy also involves significant potential dangers.
Diese Gefahrenpotenziale deuten sich angesichts zahlreicher, weltweit auftretender Brandereignisse aufgrund von nicht oder schlecht funktionierenden Akkumulatoren, beispielsweise in Smartphones oder Notebooks, bereits in zunehmendem Umfang an.These potential dangers are already increasingly evident in the face of numerous, worldwide fire events due to non-functioning or poorly functioning accumulators, for example in smartphones or notebooks.
Ein besonders hohes Risiko wird bei Bränden im Umfeld von Elektrofahrzeugen, beispielsweise bei hybrid- oder vollelektrisch betriebenen Fahrzeugen, gesehen (siehe beispielsweise "E-Mobil-Brand in den USA"; https://www.welt.de/motor/news/article120704501/E-Mobil-Brand-in-den-USA.html (abgerufen am 09.11.2016)).A particularly high risk is seen in fires in the field of electric vehicles, for example in hybrid or fully electric vehicles (see, for example, "E-Mobile Brand in the USA"; https://www.welt.de/motor/news/). article120704501 / E-Mobile-Brand-in-the-USA.html (accessed on 09.11.2016)).
Besonders problematisch beim Brand eines solchen Elektrofahrzeugs ist, dass beim Löschen nicht nur erhebliche Gefahren durch das Feuer und den Brand selbst sowie etwa mögliche selbstentzündende Elemente wie beispielsweise Lithiumionen-Akkumulatoren ausgehen, sondern zusätzlich auch noch Gefahren durch sich ausbreitende Hochspannungen bzw. Starkströme aufgrund der im Fahrzeug verbauten Hochleistungselektrik bzw. -akkumulatoren kontrolliert werden müssen bzw. es gilt, diesen wirksam vorzubeugen.Particularly problematic in the fire of such an electric vehicle is that when extinguishing not only significant hazards from the fire and the fire itself and possibly possible Selbstentzündende elements such as lithium-ion batteries, but in addition also risks due to propagating high voltages or high currents due to the vehicle installed high-performance electricity or accumulators must be controlled or it is important to prevent this effectively.
Bislang sind Brandbekämpfer nur bedingt auf die Behandlung derartiger Gefahrenquellen vorbereitet. Im oben genanntem Artikel wird beispielsweise berichtet, dass die einen Brand eines Elektrofahrzeugs bekämpfenden Feuerwehrleute deutlichen räumlichen Abstand vom Elektrofahrzeug hielten bzw. halten mussten, was natürlich die Effektivität der Brandbekämpfung ganz erheblich einschränkt oder die -an sich bekannten- Brandbekämpfungsmaßnahmen in ihrer positiven Wirkung reduziert, wenn nicht gar unmöglich macht.So far, firefighters are only partially prepared for the treatment of such hazards. For example, the above mentioned article reports that the firefighters fighting a fire of an electric vehicle had to maintain or maintain a considerable distance from the electric vehicle, which of course considerably limits the effectiveness of the firefighting or reduces the positive effects of the firefighting measures known to those skilled in the art, if not impossible.
Um mit derartigen erweiterten Gefahren umzugehen, bedarf es daher insbesondere Schutzhandschuhen, die nicht nur -jeweils als für sich-Feuerwehrhandschuhe oder als Elektrikerhandschuhe ausgebildet sind, sondern sowohl thermischen als auch mechanischen als auch elektrischen Gefahren standhalten können.In order to deal with such extended dangers, it is therefore particularly necessary to wear protective gloves which are not only designed as self-firefighter gloves or as electrician's gloves, but can withstand both thermal and mechanical and electrical hazards.
Grundsätzlich bekannt sind seit langem Spezial-Schutzhandschuhe, insbesondere Feuerwehrhandschuhe, zum Schutz vor thermischen und mechanischen Gefahren, beispielsweise die Feuerwehr-Schutzhandschuh-Modelle "Fire Fighter Premium" oder "Evolution", jeweils Fabrikate der Firma Seiz Technical Gloves GmbH in D-72555 Metzingen. Ebenso bekannt sind Schutzhandschuhe, insbesondere Elektriker-Handschuhe, die zum Schutz vor elektrischen Gefahren dienen, beispielsweise das von der Firma Seiz Technical Gloves GmbH angebotene Modell "Electrosoft".Basically known for a long time special protective gloves, especially firefighter gloves, to protect against thermal and mechanical hazards, such as the firefighters protective gloves models "Fire Fighter Premium" or "Evolution", each manufactured by Seiz Technical Gloves GmbH D-72555 Metzingen , Also known are protective gloves, especially electrician gloves, which serve to protect against electrical hazards, such as the model "Electrosoft" offered by the company Seiz Technical Gloves GmbH.
Aus der eingangs zitierten
Problematisch bleibt jedoch nach wie vor, dass ein solcher Handschuh, der vor den genannten Gefahren Schutz bieten mag, insbesondere auch die jeweiligen Einzelnormen, insbesondere die Forderungen der EN 695 und auch der EN 60903, streng zu erfüllen hat, um überhaupt in der Praxis eingesetzt werden zu dürfen.However, the problem remains that such a glove, which may offer protection against the dangers mentioned, in particular the respective individual standards, in particular the requirements of EN 695 and also EN 60903, has to be strictly met in order to be used in practice to be allowed to.
Insbesondere Anforderungen hinsichtlich des Schutzes vor Elektrizität sind aber bislang nur äußerst begrenzt auch in Kombination mit Anforderungen hinsichtlich des Schutzes vor thermischen und mechanischen Gefahren erfüllbar, unter anderem weil normengemäß hohe technische Anforderungen sowohl in nassem als auch in trockenem Zustand zu erfüllen sind, wobei ein derartiger Schutzhandschuh, welcher ausreichenden Schutz vor elektrischen Strömen und hohen Spannungen bietet, gleichzeitig Hitze- bzw. Feuerresistent ausgebildet sein müsste.In particular, requirements for the protection against electricity but so far only extremely limited in combination with requirements for protection against thermal and mechanical hazards met, inter alia because high technical standards are to be met both in wet and in dry condition according to standards, with such a Protective glove, which provides sufficient protection against electrical currents and high voltages, at the same time heat or fire resistant should be formed.
Zwar mag es für sich gesehen naheliegend erscheinen, einen derartigen Schutzhandschuh bereitzustellen, in welchem mehrere Schichten mit unterschiedlichen, normerfüllenden Schutzeigenschaften kombiniert werden. Dieses Vorgehen hat bislang jedoch noch nicht zum erwünschten Erfolg geführt, da immer noch zusätzliche weitere Detailprobleme gelöst werden müssten.While it may seem obvious to provide such a protective glove in which several layers are combined with different, norm-filling protective properties. However, this procedure has not yet led to the desired success, as still additional additional detail problems would have to be solved.
So müssten einerseits die Schichten -zumindest temporär- miteinander unlösbar verbunden sein. Beispielsweise kann man nicht einfach eine spezielle Außenhülle verwenden, die per se mechanischen Schutz bietet, und dann zusätzlich bedarfsweise beispielsweise ein Innenfutter unterziehen, um zusätzlichen thermischen Schutz zu erzielen. Hieraus ergäben sich potenziell äußerst unerwünschte anderweitige Unfallgefahren.On the one hand, on the one hand, the layers would have to be connected to one another, at least temporarily, inseparably. For example, you can not just use a special outer shell that provides mechanical protection per se, and then additionally, for example, if necessary, undergo a lining to achieve additional thermal protection. From this This would potentially result in extremely undesirable other accident hazards.
Bislang ist es noch nicht gelungen, einen Schutzhandschuh gegen thermische und/oder mechanische Gefahren zusätzlich mit einer weiteren zu versehen Hülle, die den -vergleichsweise strengengesetzlichen Normen für Elektriker-Handschuhe gerecht wird. So besteht bislang das Risiko, dass -insbesondere im nassen Zustand, wie in den Prüf-Vorschiften der Norm zwingend vorgegeben- über eine genähte Verbindung einer Außenhülle mit einer Innenhülle bzw. mit einem Elektriker-Handschuh Elektrizität in unzulässigem Ausmaß das Innere des Schutzhandschuhs erreicht.So far, it has not yet been possible to provide a protective glove against thermal and / or mechanical hazards in addition to a further shell which meets the comparatively strict regulations for electrician's gloves. So far, there is the risk that - especially in the wet state, as mandatory in the test regulations of the standard - reaches the interior of the protective glove over a sewn connection of an outer shell with an inner shell or with an electrician glove electricity to an inadmissible extent.
Aufgabe der vorliegenden Erfindung ist es demgegenüber, mit möglichst einfachen technischen Mitteln unaufwändig und kostengünstig einen Schutzhandschuh bereit zu stellen, mit dem sowohl Mindestanforderungen der einschlägigen Normen zum Schutz vor thermischen Gefahren, insbesondere der Europäischen Norm 659 für Feuerwehr-Schutzhandschuhe, als auch denen zum Schutz vor elektrischen Gefahren, insbesondere der Europäischen Norm 60903, sicher erfüllt werden können.Object of the present invention is in contrast to provide the simplest and simplest technical means inexpensive and inexpensive a protective glove, with the minimum requirements of the relevant standards for protection against thermal hazards, in particular the European Standard 659 for fire-protective gloves, as well as those for protection against electrical dangers, in particular the European standard 60903, can be safely fulfilled.
Erfindungsgemäß wird diese -in der Praxis nicht ganz unkomplizierte - Aufgabe auf ebenso überraschend einfache wie wirkungsvolle Weise gelöst durch einen isolierenden Schutzhandschuh für Arbeiten unter elektrischer Spannung, der als Fingerhandschuh mit einem Handschuhkörper und Handschuhfingern ausgeführt ist und eine vorderseitige Innenhandfläche, einen rückseitigen Handschuhrücken sowie an einem Ende eine Stulpenöffnung zur Einführung der Hand in den Fingerhandschuh aufweist, wobei der Schutzhandschuh mindestens zweilagig ausgeführt ist und ein bei Benutzung mit einer Benutzer-Hand in Berührung kommendes Innenfutter sowie eine das Innenfutter auf der Hand-abgewandten Außenseite umgebende Außenhülle aufweist,
und wobei die Außenhülle und das Innenfutter derart aufgebaut sind, dass sie gemeinsam den Mindestanforderungen der Europäischen Norm 659 für Feuerwehr-Schutzhandschuhe genügen, wobei sich der Schutzhandschuh dadurch auszeichnet, dass das Innenfutter einen spannungsisolierenden Elektriker-Handschuh umfasst, der bereits für sich den Mindestanforderungen der Europäischen Norm 60903 für isolierende Schutzhandschuhe für Arbeiten unter elektrischer Spannung genügt, dass das Innenfutter mit der Außenhülle über eine umlaufende, in sich geschlossene Klebenaht auf der Höhe des Handschuh-Stulpens verbunden ist, und dass die geschlossene Klebenaht elektrisch isolierend auch für Spannungen ≥ 1000V ausgeführt ist.According to the invention this - in practice not so straightforward task - solved in an equally surprisingly simple and effective manner by an insulating protective glove for working under electrical tension, which is designed as a finger glove with a glove body and glove fingers and a front-side palm, a back glove back and on one end has a cuff opening for the introduction of the hand in the finger glove, wherein the protective glove is designed at least two layers and one in use with a user's hand Coming into contact lining and a surrounding the inner lining on the hand-facing outside outer shell,
and wherein the outer shell and the inner lining are constructed so as to collectively meet the minimum requirements of European Standard 659 for fire-fighter protective gloves, wherein the protective glove is characterized in that the inner lining comprises a tension-insulating electrician glove, which already meets the minimum requirements of European standard 60903 for insulating protective gloves for working under electrical tension is sufficient that the inner lining is connected to the outer shell by means of a circumferential, self-adhesive seam at the level of the glove cuff, and that the closed adhesive seam is electrically insulating also for voltages ≥ 1000V is.
Dabei ist unter der Spannung diejenige Prüfspannung zu verstehen, mit der normgemäß einer jeweiligen Klasse entsprechend zu prüfen ist. Beispielsweise beträgt die (Prüf-)Spannung für die niedrigste Klasse 00 der EN 60903 mindestens 2.500V und ist somit ≥1000V.In this case, the voltage is to be understood as the test voltage with which, according to the standard, a respective class is to be correspondingly tested. For example, the (test) voltage for the lowest class 00 of EN 60903 is at least 2.500V and is thus ≥1000V.
Erfindungsgemäß kann ein Schutzhandschuh bereitgestellt werden, der für sich genommen bereits die Europäische Norm 659 für Feuerwehr-Schutzhandschuhe erfüllt. In diesen Schutzhandschuh ist mittels des Innenfutters ein spannungsisolierender Elektriker-Handschuh integriert, welcher für sich die Mindestanforderungen der Europäischen Norm 60903 erfüllt.According to the invention, a protective glove can be provided, which in itself already fulfills the European standard 659 for fire-fighting protective gloves. In this protective glove by means of the inner lining a tension-insulating electrician glove is integrated, which meets the minimum requirements of the European standard 60903.
Das Innenfutter ist über eine in sich geschlossene, elektrisch isolierende Klebenaht mit der Außenhülle verbunden. Durch Verwendung einer solchen speziellen Klebenaht kann eine Perforation des Elektriker-Handschuhs, wie sie sonst bei einer sonst üblichen genähten Naht unvermeidlich wäre, vermieden werden. Somit kann der erfindungsgemäße Schutzhandschuh allen genannten Normen gleichzeitig gerecht werden.The inner lining is connected via a self-contained, electrically insulating adhesive seam with the outer shell. By using such a special adhesive seam, a perforation of the electrician glove, as otherwise in a conventional sewn seam would be inevitable, avoided. Thus, the protective glove of the invention can meet all the standards mentioned at the same time.
Durch eine dennoch feste, zumindest zeitweise unlösbare Verbindung der Einzelteile miteinander können zudem die oben beschriebenen Unfallrisiken vermieden werden.By still firm, at least temporarily unsolvable connection of the individual parts with each other, the accident risks described above can also be avoided.
Durch Platzierung der Klebenaht auf der Höhe des Handschuh-Stulpens kann des Weiteren sicher gestellt werden, dass zu jeder Zeit der Schutz gegen elektrische Gefahren sich jedenfalls mindestens so weit über die Körperoberfläche der Benutzer-Hand erstreckt wie auch der -im Wesentlichen durch die Außenhülle gebildete- Schutz gegen thermische Gefahren wirkt. Insbesondere wird ein Verrutschen des Elektriker-Handschuhs vermieden, wodurch beispielsweise Teile des Handrückens zwar ggf. noch vor thermischen Gefahren, nicht aber mehr vor Elektrizität geschützt wären.By placing the adhesive seam at the level of the glove cuff can further be ensured that at any time the protection against electrical hazards extends at least as far over the body surface of the user's hand as well as the-formed essentially by the outer shell - Protection against thermal hazards acts. In particular, slippage of the electrician's glove is avoided, whereby, for example, parts of the back of the hand might still be protected from thermal hazards, but not from electricity.
Eine besonders vorteilhafte Klasse von Ausführungsformen ist dadurch gekennzeichnet, dass die Außenhülle einlagig aus Hitze-isolierendem, flammfestem Material, vorzugsweise aus Aramid und/oder aus Para-Aramid, aufgebaut ist und den Mindestanforderungen der Europäischen Norm 407 für Schutzhandschuhe gegen thermische Risiken genügt.A particularly advantageous class of embodiments is characterized in that the outer shell is constructed in one layer of heat-insulating, flame-resistant material, preferably aramid and / or para-aramid, and meets the minimum requirements of European Standard 407 for protective gloves against thermal risks.
Somit kann bereits die Außenhülle einen hinreichenden thermischen Schutz gewährleisten. Schichten aus Aramid, Meta-Aramid, und/oder Para-Aramid bieten ferner den Vorteil, auch gegen mechanische Gefahren zu schützen, d. h. beispielsweise einen Schnitt- und/oder Durchstichschutz zu bieten. Auch weisen diese Schichten eine geringe Wärmeleitfähigkeit auf.Thus, even the outer shell can ensure adequate thermal protection. Layers of aramid, meta-aramid, and / or para-aramid also have the advantage of protecting against mechanical hazards, ie, for example, to provide cut and / or puncture protection. Also, these layers have a low thermal conductivity.
Es versteht sich, dass auch weitere, insbesondere textile, Zwischenschichten zwischen Außenhülle und Innenfutter, beispielsweise aus Para-Aramid und/oder Aramid, vorgesehen sein können.It is understood that other, in particular textile, intermediate layers between outer shell and inner lining, for example of para-aramid and / or aramid, may be provided.
Auch kann vorgesehen sein, dass die Außenhülle, insbesondere die vorderseitige Innenhandfläche, aus einem abriebfesten, schnittfesten und durchstichfesten Material aufgebaut, vorzugsweise beschichtet ist, beispielsweise mit Silikon oder Silikon-Carbon oder anderen flammfesten Kunststoffen, und bereits für sich zumindest den Anforderungen der Europäischen Norm 388 für Schutzhandschuhe gegen mechanische Risiken genügt.It may also be provided that the outer shell, in particular the front-side palm of the hand, is constructed, preferably coated, of an abrasion-resistant, cut-resistant and puncture-resistant material, for example with silicone or silicone-carbon or other flame-resistant plastics, and at least meets the requirements of the European Standard 388 for protective gloves against mechanical risks is sufficient.
Während ein üblicher Elektriker-Handschuh keinerlei bzw. kaum Schutz gegen mechanische Gefahren bietet, kann somit ein Schutzhandschuh bereitgestellt werden, der Schutz gegen thermische, mechanische als auch elektrische Gefahren bietet. Somit können völlig neue Einsatzgebiete für Schutzhandschuhe erschlossen werden. Ebenso genügt dem Benutzer ein einziger Schutzhandschuh-Typus zur Abwehr der genannten Gefahren. Ein zwischenzeitliches Wechseln des Schutzhandschuhs während eines Einsatzes entfällt.While a conventional electrician's glove offers no or little protection against mechanical hazards, a protective glove can be provided which provides protection against thermal, mechanical and electrical hazards. Thus, completely new applications for protective gloves can be developed. Likewise, the user is satisfied with a single type of protective gloves to ward off the dangers mentioned. An interim change of the protective glove during use is eliminated.
Ein solcher mehrlagiger Aufbau des Schutzhandschuhs kann auch gewährleisten, dass der Elektriker-Handschuh bzw. das Innenfutter ebenfalls vor mechanischen Einflüssen und/oder Verschleiß geschützt wird, wodurch sich dessen Haltbarkeit bzw. Lebensdauer verlängern lässt.Such a multi-layer construction of the protective glove can also ensure that the electrician's glove or the inner lining is also protected from mechanical influences and / or wear, which can extend its durability or lifetime.
Bei einer weiteren Ausführungsform kann die Außenhülle auch einen mehrlagig aufgebauten Feuerwehr-Schutzhandschuh umfassen, der bereits für sich zumindest den Mindestanforderungen der Europäischen Norm 659 für Feuerwehr-Schutzhandschuhe genügt.In a further embodiment, the outer shell may also comprise a multi-layered fire department protective glove which at least meets the minimum requirements of European Standard 659 for fire-fighter protective gloves.
Besonders vorteilhaft ist auch, wenn die das Innenfutter mit der Außenhülle verbindende umlaufende, in sich geschlossene, elektrisch isolierende Klebenaht um den Rand der Stulpenöffnung herum verläuft.It is also particularly advantageous if the peripheral, self-contained, electrically insulating adhesive seam connecting the inner lining with the outer shell extends around the edge of the cuff opening.
Somit kann die Klebenaht einerseits geschützt abseits des Hauptaktionsbereichs, insbesondere des Griffbereichs des Schutzhandschuhs, angeordnet sein. Auch kann dadurch ein den Schutzhandschuh rundum umfassender Elektrizitätsschutz gewährleistet werden.Thus, the adhesive seam on the one hand be protected away from the main action area, in particular the handle portion of the protective glove, be arranged. Also, this can be a protective glove all-encompassing electricity protection guaranteed.
Alternativ kann die das Innenfutter mit der Außenhülle verbindende umlaufende, in sich geschlossene, elektrisch isolierende Klebenaht mit Abstand von der Stulpenöffnung in Richtung auf die Handschuhfinger hin zwischen der Hand-zugewandten Innenseite der Außenhülle und der Hand-abgewandten Außenseite des Innenfutters verlaufen.Alternatively, the circumferential, self-contained, electrically insulating adhesive seam connecting the inner lining with the outer shell can extend with distance from the cuff opening in the direction of the glove fingers between the hand-facing inner side of the outer shell and the outer side of the inner lining facing away from the hand.
Besonders vorteilhaft ist es, wenn zwischen der Hand-zugewandten Innenseite der Außenhülle und der Hand-abgewandten Außenseite des Innenfutters auch an den Fingerspitzen der Handschuhfinger eine elektrisch isolierende Klebeschicht vorhanden ist. Somit kann vermieden werden, dass das Innenfutter aus der Außenhülle (unbeabsichtigt) herausgezogen und dadurch unbrauchbar gemacht wird.It is particularly advantageous if an electrically insulating adhesive layer is also present at the fingertips of the glove fingers between the hand-facing inner side of the outer shell and the outer side of the inner lining facing away from the hand. Thus, it can be avoided that the inner lining of the outer shell (unintentionally) pulled out and thus made unusable.
Die umlaufende, in sich geschlossene, elektrisch isolierende Klebenaht und/oder eine elektrisch isolierende Klebeschicht können aus einem oder mehreren elektrisch nicht-leitfähigen Klebstoffen hergestellt sein, insbesondere aus organischen oder anorganischen Klebstoffen, vorzugsweise auf Silikon-Basis.The circulating, self-contained, electrically insulating adhesive seam and / or an electrically insulating adhesive layer may be made of one or more electrically non-conductive adhesives, in particular of organic or inorganic adhesives, preferably based on silicone.
Insbesondere können die Klebstoffe Einkomponenten-, Zweikomponenten- oder Mehrkomponenten-Klebstoffe sein.In particular, the adhesives may be one-component, two-component or multi-component adhesives.
Ein besonderer Vorteil ergibt sich, wenn die umlaufende, in sich geschlossene, elektrisch isolierende Klebenaht und/oder eine elektrisch isolierende Klebeschicht eine Schichtdicke ≥ 0,5mm aufweisen. Dadurch kann gleichzeitig ein vorteilhafter Abstand zwischen Außenhülle und Innenfutter gewährleistet werden.A particular advantage is obtained when the circumferential, self-contained, electrically insulating adhesive seam and / or an electrically insulating adhesive layer have a layer thickness ≥ 0.5 mm. As a result, at the same time an advantageous distance between the outer shell and inner lining can be ensured.
Bei einer Klasse von Ausführungsformen verbindet die umlaufende, in sich geschlossene, elektrisch isolierende Klebenaht und/oder eine elektrisch isolierende Klebeschicht die Außenhülle unlösbar mit dem Innenfutter. Somit können für den Benutzer auch eine hinreichende Sicherheit bzw. umfassende Sicherheitseigenschaften der beiden Hüllen sichergestellt werden.In one class of embodiments, the circumferential, self-contained, electrically insulating adhesive seam and / or an electrically insulating adhesive layer inextricably connects the outer shell with the inner lining. Thus, a sufficient security or comprehensive security properties of the two cases can be ensured for the user.
Bei einer alternativen Klasse von Ausführungsformen ist dagegen vorgesehen, dass die umlaufende, in sich geschlossene, elektrisch isolierende Klebenaht und/oder eine elektrisch isolierende Klebeschicht derart beschaffen sind, dass sie die Außenhülle nur zeitweise untrennbar mit dem Innenfutter verbinden, so dass das Innenfutter nach einem vorbestimmten Ablaufdatum, vorzugsweise nach dem vorgeschriebenen Verfallsdatum von 2 Jahren für Elektriker-Handschuhe, von der Außenhülle gelöst und aus dieser herausgezogen werden kann. Dadurch kann der Schutzhandschuh besonders wirtschaftlich attraktiv hergestellt und genutzt werden. Insbesondere kann die Außenhülle auch wiederverwendet bzw. weiterbenutzt werden, selbst wenn aufgrund beispielsweise gesetzlicher Vorgaben das
Innenfutter bzw. der Elektriker-Handschuh auszuwechseln ist.In an alternative class of embodiments, on the other hand, it is provided that the encircling, self-contained, electrically insulating adhesive seam and / or an electrically insulating adhesive layer are such that they temporarily connect the outer shell inseparably with the inner lining, so that the inner lining according to a predetermined expiration date, preferably after the prescribed expiration date of 2 years for electrician's gloves, detached from the outer shell and can be pulled out of this. As a result, the protective glove can be produced and used in an especially economically attractive manner. In particular, the outer shell can also be reused or reused, even if due to legal requirements, for example
Inner lining or the electrician glove is replaced.
Besonders bevorzugt ist dabei, wenn die Klebenaht und/oder Klebeschicht mindestens einen thermisch aktivierbaren Klebstoff aufweist. Dann kann das Trennen der beiden Schichten voneinander durch Erwärmen bzw. thermisches Aktivieren des Klebstoffs erfolgen. Dabei ist anzumerken, dass die Aktivierungstemperatur in einem von der Einsatztemperatur, insbesondere der Einsatz-Innentemperatur, des Schutzhandschuhs abweichenden, insbesondere höheren Bereich vorzugsweise gewählt werden kann.It is particularly preferred if the adhesive seam and / or adhesive layer has at least one thermally activatable adhesive. Then, the separation of the two layers from each other by heating or thermal activation of the adhesive take place. It should be noted that the activation temperature may be preferably selected in a range that deviates from the operating temperature, in particular the internal use temperature, of the protective glove, in particular the higher range.
Beispielsweise kann zur Herstellung zunächst der thermisch aktivierbare Klebstoff entsprechend der auszubildenden Klebenaht bzw. Klebenähte auf das Innenfutter aufgebracht werden. Dann kann das Innenfutter in die Außenhülle eingebracht werden. Durch Zusammenpressen und/oder - insbesondere wenn dies der thermisch aktivierbare Klebstoff erfordert - durch Erhitzen des Innenfutters und/oder der Außenhülle können beide Teile zusammengefügt werden. Beispielsweise zur Auswechslung des Innenfutters genügt es dann, den Klebstoff, insbesondere durch Erhitzen, zu aktivieren und dadurch die beiden Teile wieder voneinander zu lösen. Anschließend kann beispielsweise ein neuer Elektriker-Handschuh als Innenfutter mit der bereits vorhandenen Außenhülle analog zum vorigen Vorgehen zusammengefügt werden.For example, for the production of the first thermally activated adhesive can be applied to the inner lining according to the adhesive seam or adhesive seams to be formed. Then the inner lining can be inserted into the outer shell. By compressing and / or - in particular if this requires the thermally activated adhesive - by heating the inner lining and / or the outer shell, both parts can be joined together. For example, to replace the inner lining, it is then sufficient to activate the adhesive, in particular by heating, thereby releasing the two parts from each other again. Subsequently, for example, a new electrician glove can be assembled as inner lining with the existing outer shell analogous to the previous procedure.
Eine besonders einfache Herstellung des Schutzhandschuhs bzw. seines Innenfutters ergibt sich ferner, wenn das Innenfutter nahtlos getaucht oder gespritzt ist.A particularly simple production of the protective glove or its inner lining also results when the inner lining is seamlessly dipped or sprayed.
Die Außenhülle kann nahtlos von den Fingerspitzen der Handschuhfinger bis zum Stulpenende der Einführöffnung gestrickt sein. Dadurch lässt sich eine vorteilhafte Beweglichkeit als auch ein günstiges Tastvermögen des Schutzhandschuhs erreichen. Bedingt durch die Dehnfähigkeit der gestrickten Textils kann sich zudem die Außenhülle dem Innenfutter optimal anpassen. Auch befinden sich dadurch keine störenden Nähte an der Außenhülle.The outer shell can be seamlessly knitted from the fingertips of the glove fingers to the cuff end of the insertion opening be. As a result, an advantageous mobility as well as a favorable tactile capability of the protective glove can be achieved. Due to the stretchability of the knitted textile, the outer shell can also optimally adapt to the inner lining. Also, there are no disturbing seams on the outer shell.
