Description

Die Erfindung betrifft einen Sicherheitsschrank, vorzugsweise einen Sicherheits-Untertischschrank, mit wenigstens einem Schrankkorpus, und mit zumindest einer an den Schrankkorpus angelenkten Tür.The invention relates to a safety cabinet, preferably a safety underbench cabinet, with at least one cabinet body, and with at least one door hinged to the cabinet body.

Solche Schränke, insbesondere Sicherheitsschränke, sind allgemein bekannt, wozu nur beispielhaft auf die DE 93 17 218 U1 hingewiesen sei. Regelmäßig werden derartige Schränke, bzw. Untertischschränke unterhalb von Labortischen platziert. In Labors kommen oftmals nicht nur Gefahrstoffe wie brennbare Flüssigkeiten (beispielsweise Alkohole), sondern auch Säuren oder Laugen zum Einsatz.Such cabinets, especially safety cabinets, are well known, including only by way of example to the DE 93 17 218 U1 is pointed out. Such cabinets, or undercounter cabinets are regularly placed below laboratory benches. In laboratories, not only hazardous substances such as flammable liquids (eg alcohols), but also acids or alkalis are often used.

Die Bevorratung solcher Säuren und Laugen muss einerseits getrennt von den zuvor angesprochenen Gefahrstoffen erfolgen und ist andererseits problematisch, was die dauerhafte Unterbringung angeht. Denn beispielsweise Säuredämpfe (oder auch Laugendämpfe) greifen nahezu alle Materialien an, aus denen solche Sicherheits-Schränke aufgebaut sind, namentlich Metallplatten, Scharniere, Griffe, Schienenführungen etc. Da heutzutage zunehmend die Anforderung besteht, nicht nur Gefahrstoffe, sondern auch Säuren und Laugen verbrauchsnah zu lagern, müssen geeignete Vorkehrungen getroffen werden. Denn viele Labors gehen mehr und mehr dazu über, bisher ausgelagerte Chemikalienvorräte von ihrer Menge her zu verringern und direkt in den Labors zu lagern, um die Wege und etwaige Ausfallzeiten so kurz wie möglich zu bemessen.The storage of such acids and alkalis on the one hand must be done separately from the aforementioned hazardous substances and on the other hand is problematic in terms of permanent housing. For example, acid fumes (or even lukewarms) attack almost all materials from which such security cabinets are built, namely metal plates, hinges, handles, rail guides, etc. Nowadays there is an increasing demand, not only hazardous substances, but also acids and alkalis consumption near to store, appropriate precautions must be taken. After all, many labs are increasingly reducing the amount of previously stored chemical supplies and storing them directly in the laboratories to minimize the distances and possible downtimes for as short a time as possible.

Im Rahmen der gattungsbildenden Lehre nach der US 5 664 853 ist ein Schrank bekannt geworden, welcher im Inneren des Schrankkorpus mit einzelnen Abteilungen ausgerüstet ist. Diese Abteilungen werden einerseits von vertikalen und andererseits von horizontalen Paneelen definiert. Die fraglichen Paneele sind überwiegend nicht an den Schrankkorpus angeschlossen, sondern definieren eine separate Struktur im Inneren.As part of the generic teaching after the US 5,664,853 has become known a cabinet, which is inside the cabinet body with individual departments. These departments are defined on the one hand by vertical and on the other by horizontal panels. The panels in question are predominantly not connected to the cabinet body, but define a separate structure in the interior.

DE 94 16 974 U zeigt einen Sichercheitsschrank, ausgebildet mit einerh zweiteiligen Schrankkorpus, einer Gefahrstoffabteilung und einer Säure-/Laugen-Abteilung mit Innenverkleidung. DE 94 16 974 U shows a safety cabinet, formed with a two-piece cabinet body, a hazardous materials department and an acid / alkaline department with interior trim.

Der Erfindung liegt das technische Problem zugrunde, einen Schrank, insbesondere Sicherheitsschrank, der eingangs beschriebenen Ausgestaltung so weiter zu entwickeln, dass die problemlose Lagerung von sämtlichen im Labor benötigten Materialien, insbesondere von Säuren und Laugen, gelingt.The invention is based on the technical problem of further developing a cabinet, in particular a safety cabinet, of the embodiment described at the beginning in such a way that the problem-free storage of all materials required in the laboratory, in particular of acids and alkalis, succeeds.

Zur Lösung dieser technischen Problemstellung ist ein gattungsgemäßer Sicherheitsschrank im Rahmen der Erfindung dadurch gekennzeichnet, dass der Schrankkorpus wenigstens zweiteilig mit einer Gefahrstoffabteilung und einer Säure-/Laugen-Abteilung mit Innenverkleidung ausgebildet ist, wobei die vom Schrankkorpus unabhängige Innenverkleidung resistent gegenüber Säuren und Laugen ausgeführt ist und das Innere des Schrankkorpus teilweise bedeckt sowie einen eigenen Raumkörper getrennt vom Schrankkorpus bildet und dazu die Innenverkleidung mehrteilig mit Bodenverkleidungsteil und Dachverkleidungsteil sowie Wandverkleidungsteilen ausgebildet ist, welche unabhängig vom Schrankkorpus eine selbsttragende Hülle bilden und einzeln dauerhaft oder lösbar mittels gegenüber Säure und Laugen resistenten Befestigungsmitteln mit dem Schrankkorpus verbunden sind, und wobei etwaige zwischen den einzelnen Verkleidungsteilen verbleibende Fugen nach Anbringung der Innenverkleidung im Schrankkorpus versiegelt werden.To solve this technical problem, a generic safety cabinet is within the scope of the invention characterized in that the cabinet body is formed at least two parts with a hazardous substances department and an acid / alkaline department with inner lining, wherein the cabinet carcass independent interior lining is made resistant to acids and alkalis and the interior of the cabinet body partially covered and forms a separate space body separate from the cabinet body and the inner lining is formed in several parts with floor covering and roof trim part and wall covering parts which form a self-supporting shell independently of the cabinet body and individually permanently or detachably by means of acid and alkali resistant fasteners the cabinet body are connected, and wherein any remaining between the individual trim parts joints are sealed after installation of the inner lining in the cabinet body.

Die erfindungsgemäße Innenverkleidung ist also unabhängig vom Schrankkorpus ausgelegt. Das meint im Rahmen der Erfindung, dass die Innenverkleidung getrennt von dem Schrankkorpus gefertigt wird und/oder einen eigenen Raukörper getrennt vom Schrankkorpus bildet. Dadurch lässt sich ein vorhandener Schrankkorpus bedarfsweise mit der Innenverkleidung ausrüsten und der Schrank entsprechend aufrüsten. Die Verbindung der Innenverkleidung mit dem Schrankkorpus ist dauerhaft oder auch lösbar gestaltet. Hier schlägt die Erfindung spezielle Befestigungsmittel vor, welche resistent gegenüber Säuren und Laugen ausgeführt sind. Als Befestigungsmittel haben sich beispielsweise so genannte Kunststoffnägel als günstig erwiesen. Denn mit Hilfe der Kunststoffnägel lässt sich die Innenverkleidung einerseits gegenüber dem Schrankkorpus sichern und andererseits in ihrer gewünschten Position gegenüber dem Schrankkorpus fixieren.The inner lining according to the invention is thus designed independently of the cabinet body. This means in the context of the invention that the inner lining is made separately from the cabinet body and / or forms its own shell separate from the cabinet body. This allows an existing cabinet body, if necessary, equipped with the interior trim and upgrade the cabinet accordingly. The connection of the inner lining with the cabinet body is permanently or detachably designed. Here, the invention proposes special fasteners that are resistant to acids and alkalis. As a fastener, for example, so-called plastic nails have proven to be favorable. Because with the help of plastic nails, the inner lining can on the one hand secure against the cabinet body and on the other hand fix in their desired position relative to the cabinet body.

Die Innenverkleidung ist - wie die Befestigungsmittel - resistent gegenüber Säuren und Laugen ausgebildet. Dabei hat es sich ganz besonders bewährt, wenn die Innenverkleidung ganz oder teilweise selbsttragend ausgebildet ist. Das heißt, die Verkleidung kommt ohne einen eigenen stützenden Rahmen aus, ist vielmehr in der Lage, gleichsam ohne denThe inner lining is - like the fasteners - resistant to acids and alkalis. It has proven particularly useful when the interior trim is completely or partially self-supporting. That is, the disguise does not have its own supporting frame, but rather is able to do so without it

Schrankkorpus eine Einhausung, also einen geschlossenen Raumkörper, zu bilden. Anders ausgedrückt, werden tragende Funktionen der Innenverkleidung von dieser selbst übernommen. Alle Verkleidungsteile wirken folglich als gleichsam Schalen und nehmen in ihrer Gesamteinheit eingeleitete Kräfte auf.Cabinet body an enclosure, so a closed room body to form. In other words, supporting functions of the interior lining are taken over by this itself. All trim parts consequently act as shells and absorb forces introduced in their total unit.

Dabei hat es sich besonders bewährt, wenn die Innenverkleidung aus einem Kunststoff, beispielsweise einem thermoplastischen Kunststoff hergestellt ist. Beispiele für geeignete Kunststoffe sind Polyethylen oder auch Polypropylen. So ist es bekannt, dass beispielsweise aus Polyethylen (PE) säurefeste Behälter und Rohre sowie Folien hergestellt werden können. Auch Polypropylen (PP) eignet sich hierfür und wird beispielsweise für die Herstellung von Batteriekästen genutzt. Jedenfalls zeichnen sich solche thermoplastischen Kunststoffe im Allgemeinen und Polyethylen, Polypropylen aber auch Polyamid (PA) im Speziellen durch ihre besondere Eignung aus, als Material für die erfindungsgemäß eingesetzte und vorzugsweise selbsttragende Innenverkleidung des Schrankkorpus zu dienen.It has proven particularly useful if the inner lining is made of a plastic, such as a thermoplastic material. Examples of suitable plastics are polyethylene or polypropylene. It is thus known that, for example, polyethylene (PE) can be used to produce acid-resistant containers and pipes as well as films. Also polypropylene (PP) is suitable for this and is used for example for the production of battery boxes. In any case, such thermoplastics in general and polyethylene, polypropylene but also polyamide (PA) in particular by their particular suitability to serve as a material for the inventively used and preferably self-supporting interior trim of the cabinet body.

Dabei hat es sich ergänzend als besonders günstig erwiesen, wenn der Schrankkorpus wenigstens zweigeteilt ausgestaltet ist. Hierdurch trägt die Erfindung dem Umstand Rechnung, dass Gefahrstoffe einerseits und Säuren sowie Laugen etc. andererseits nicht gemeinsam, sondern nur getrennt bevorratet werden dürfen. Folgerichtig verfügt der erfindungsgemäße Schrankkorpus vorteilhaft über eine Gefahrstoffabteilung und eine Säure-/Laugen-Abteilung. Die Gefahrstoffabteilung dient zur Bevorratung von meistens brennbaren Gefahrstoffen wie Alkoholen etc., während die Säure-/Laugen-Abteilung Säuren, Laugen oder vergleichbare Flüssigkeit aufnimmt.It has additionally proven to be particularly favorable when the cabinet body is designed at least two parts. As a result, the invention takes into account the fact that hazardous substances on the one hand and acids and alkalis, etc. on the other hand may not be stored together, but only separately. Consequently, the cabinet body according to the invention advantageously has a hazardous substances department and an acid / alkaline department. The Hazardous Substance Department is used to store mostly flammable hazardous substances such as alcohols, etc., while the acid / alkaline department absorbs acids, lyes or similar liquids.

Im Rahmen der Erfindung wird nun die Auslegung zu getroffen, dass lediglich die Säure-/Laugen-Abteilung mit der beschriebenen Innenverkleidung ausgerüstet ist. Dadurch kann der Schrank besonders kostengünstig hergestellt werden. Denn die Innenverkleidung wird lediglich in dem Bereich des Schrankkorpus eingesetzt, welcher Säure- bzw. Laugendämpfen und folglich einem erhöhten Verschleiß ausgesetzt ist. Dabei trägt die Erfindung dem Umstand Rechnung, dass solche Sicherheitsschränke in der Regel als Stahlschränke oder auch Holzschränke mit beispielsweise Kunststoffbeschichtung ausgebildet sind. Jedenfalls wird durch die Kunststoff-Innenverkleidung sichergestellt, dass insbesondere die Säure-/Laugen-Abteilung des Schrankkorpus geschützt wird, was zwangsläufig entstehende Säure-/Laugendämpfe angeht.In the context of the invention, the design is now to be made that only equipped the acid / alkaline department with the described interior trim is. As a result, the cabinet can be produced particularly inexpensively. Because the inner lining is used only in the region of the cabinet body, which is exposed to acid or Laugendämpfen and consequently increased wear. The invention takes into account the fact that such safety cabinets are usually designed as steel cabinets or wooden cabinets with, for example, plastic coating. In any case, it is ensured by the plastic inner lining, that in particular the acid / alkaline compartment of the cabinet body is protected, which inevitably related acid / alkali vapors.

Um dies im Detail zu realisieren, hat es sich bewährt, wenn die Innenverkleidung mehrteilig ausgebildet ist. Dabei ist es beispielsweise denkbar, mit einem Bodenverkleidungsteil und einem Dachverkleidungsteil sowie mehreren Wandverkleidungsteilen zu arbeiten. Selbstverständlich können auch einzelne der vorerwähnten Verkleidungsteile zusammengefasst werden. Das lässt sich so bewerkstelligen, dass beispielsweise das Bodenverkleidungsteil und ein oder mehrere Wandverkleidungsteile einstückig ausgelegt sind. - Solche Ausführungsformen sind grundsätzlich bekannt, wozu nur beispielhaft auf das Gebrauchsmuster DE 1 920 640 U1 verwiesen sei. Allerdings geht es hier um einen Kunststoffkasten für den Innenausbau von Lieferwagen, wird also eine völlig andere Technologie beschrieben.In order to realize this in detail, it has proven useful if the interior lining is designed in several parts. It is conceivable, for example, to work with a floor covering part and a roof covering part and several wall covering parts. Of course, individual of the aforementioned trim parts can be summarized. This can be done so that, for example, the floor covering part and one or more wall covering parts are designed in one piece. - Such embodiments are basically known, including only by way of example to the utility model DE 1 920 640 U1 referenced. However, this is a plastic box for the interior of vans, so a completely different technology is described.

Um den gewünschten und vorzugsweise realisierten selbsttragenden Aufbau der Innenverkleidung herstellen zu können, hat es sich bewährt, wenn einzelne Verkleidungsteile wenigstens teilweise gegeneinander fixiert sind. Alternativ oder zusätzlich lassen sich die besagten Verkleidungsteile auch aufeinander stehend im Innern des Schrankkorpus platzieren. Dabei sorgt ergänzend der die Innenverkleidung umschließende Schrankkorpus dafür, dass die Innenverkleidung einen Halt erfährt. So oder so bilden die einzelnen Verkleidungsteile unabhängig von dem Schrankkorpus vorteilhaft eine selbsttragende Hülle, also einen zur Tür hin offenen Quader, der zusammen mit der Tür die Einhausung formt. Die Verkleidungsteile lassen sich folglich problemlos beispielsweise bei einem schon vorhandenen Schrankkorpus nachrüsten. Selbstverständlich ist auch die Neuausrüstung unschwer denkbar und wird von der Erfindung umfasst. Dabei werden etwaige und zwischen den einzelnen Verkleidungsteilen verbleibende Fugen nach Anbringung der Innenverkleidung im Schrankkorpus gegebenenfalls versiegelt.In order to produce the desired and preferably realized self-supporting structure of the interior trim, it has proven useful if individual trim parts are at least partially fixed against each other. Alternatively or additionally, said lining parts can also be placed one on top of the other inside the cabinet body. In addition, the cabinet body enclosing the inner lining ensures that the inner lining gets a hold. Either way, the individual trim parts form regardless of the cabinet body advantageously a self-supporting shell, so an open towards the door cuboid, which forms the housing together with the door. Consequently, the trim parts can be easily retrofitted, for example, to an already existing cabinet body. Of course, the new equipment is easily conceivable and is encompassed by the invention. Any remaining joints between the individual trim parts are optionally sealed after installation of the interior trim in the cabinet carcass.

Neben dem Inneren des Schrankkorpus bzw. der Säure-/Laugen-Abteilung hat es sich bewährt, wenn die an den Schrankkorpus angelenkte Tür ein daran angebrachtes Türverkleidungsteil aufweist. Dieses Türverkleidungsteil mag mit der Tür verklebt oder sonst wie adhäsiv oder auf andere Art und Weise verbunden sein. Das gilt grundsätzlich auch für die übrigen Verkleidungsteile der Innenverkleidung, die ebenfalls mit dem Schrankkorpus adhäsiv verbunden werden können. Nach besonders bevorzugter Ausführungsform werden die einzelnen Verkleidungsteile jedoch mit Hilfe der speziellen Befestigungsmittel aus Kunststoff, insbesondere mittels der Kunststoffnägel, mit dem Schrankkorpus verbunden. Das kann lösbar erfolgen.In addition to the interior of the cabinet body or the acid / alkaline department, it has proven useful if the door hinged to the cabinet body has a door panel attached thereto. This door trim part may be glued to the door or otherwise connected as adhesive or in some other way. This also applies in principle to the other trim parts of the interior trim, which can also be adhesively connected to the cabinet body. According to a particularly preferred embodiment, however, the individual covering parts are connected to the cabinet body with the aid of the special fastening means made of plastic, in particular by means of the plastic nails. This can be done solvable.

Dadurch lässt sich insgesamt die Auslegung so treffen, dass ein etwaiges Türscharnier oder andere Funktionselemente außerhalb der von den sämtlichen Verkleidungsteilen (also dem Bodenverkleidungsteil, dem Dachverkleidungsteil, den Wandverkleidungsteilen und dem Türverkleidungsteil) gebildeten Einhausung angeordnet werden können. Das heißt, die aus den Verkleidungsteilen gebildete Einhausung für die Säure, Laugen etc. bildet eine gleichsam innere und nahezu geschlossene Schale in dem Sicherheitsschrank bzw. der Säure-/Laugen-Abteilung. Außerhalb dieser Schale befinden sich der Schrankkorpus und etwaige Funktionselemente des Schrankkorpus wie Scharniere, Schlösser, Verriegelungsstangen etc. Dadurch werden diese Funktionselemente bzw. die einzelnen Teile des Schrankkorpus von zwangsläufig entstehenden Säuredämpfen oder auch Laugendämpfen separiert. Denn erfindungsgemäß ist an dieser Stelle jeweils die Innenverkleidung zwischengeschaltet.As a result, the overall design can be such that a possible door hinge or other functional elements can be arranged outside the enclosure formed by all the trim parts (ie the floor covering part, the roof covering part, the wall covering parts and the door trim part). That is, the enclosure formed by the fairing parts for the acid, alkalis, etc. forms a quasi-inner and almost closed shell in the security cabinet or the acid / alkaline department. Outside of this shell are the cabinet body and any functional elements of the cabinet body such as hinges, Locks, locking rods, etc. Thus, these functional elements or the individual parts of the cabinet body of inevitably resulting acid vapors or Laughing vapors are separated. Because according to the invention in each case the inner lining is interposed.

Da die einzelnen Verkleidungsteile der Innenverkleidung fugenlos oder größtenteils fugenlos aneinander anschließen respektive etwaige verbleibende Fugen mit ebenfalls säure-/laugenresistenten Kunststoffen verschlossen werden, ist sichergestellt, dass die sich im Innern praktisch zwangsläufig bildenden Säuredämpfe oder auch Laugendämpfe nicht bis zum Schrankkorpus respektive dessen Funktionselementen vordringen können. Denn der betreffende erfindungsgemäße Sicherheitsschrank verfügt in der Regel über eine Saugöffnung und steht mit einer ohnehin im Labor vorhandenen Absaugeinheit in Verbindung. Das heißt, die betreffenden Dämpfe werden durchgängig abgesaugt.Since the individual trim parts of the interior trim seamlessly or largely seamlessly connect each other or any remaining joints are also sealed with acid / alkali-resistant plastics, it is ensured that the inevitable inside forming acid fumes or lye vapor can not penetrate to the cabinet body respectively its functional elements , For the relevant safety cabinet according to the invention generally has a suction opening and communicates with a suction unit which is present anyway in the laboratory. This means that the relevant vapors are continuously sucked off.

Schlussendlich hat es sich bewährt, wenn auch etwaige Einbauelemente im Innern der Säure-/Laugen-Abteilung bzw. innenseitig der Innenverkleidung ebenfalls aus einem resistenten Material realisiert werden. Bei diesen Einbauelementen mag es sich nicht einschränkend um eine Schienenführung für eine Schublade handeln. Diese Schienenführung ist - wie die Verkleidungsteile - vorteilhaft aus Polypropylen oder auch Polyethylen oder einem vergleichbaren thermoplastischen Kunststoff gefertigt. Dadurch wird die gewünschte Resistenz gegenüber Säuren/Laugen erreicht. Zur Befestigung der Schienenführung können Befestigungsteile aus Polyamid eingesetzt werden. Aus diesem Material sind üblicherweise auch die erforderlichen Rollen für die Schublade hergestellt.Finally, it has proven useful, even if any built-in elements inside the acid / alkali department or on the inside of the inner lining are also made of a resistant material. These built-in elements may not be limiting to a rail guide for a drawer. This rail guide is - like the trim parts - advantageously made of polypropylene or polyethylene or a similar thermoplastic material. As a result, the desired resistance to acids / alkalis is achieved. To attach the rail guide fasteners made of polyamide can be used. From this material usually the necessary roles for the drawer are made.

Bei der Realisierung der bereits angesprochenen Schublade wird man vorteilhaft ebenfalls auf einen thermoplastischen Kunststoff zurückgreifen, der gegenüber Säuren/Laugen oder dergleichen resistent ist. Das heißt, sämtliche Einbauten oder auch beweglichen Teile im Innern der von der Innenverkleidung gebildeten Hülle sind vorteilhaft ebenfalls aus einem resistenten Material, beispielsweise einem thermoplastischen Kunststoff, hergestellt. Dabei formt die aus den einzelnen Verkleidungsteilen gebildete selbsttragende Hülle in Verbindung mit dem Türverkleidungsteil insgesamt einen nahezu geschlossenen Raum bzw. die Einhausung, welche lediglich zwischen dem Türverkleidungsteil und der übrigen Hülle einen (gering bemessenen) Spalt aufweist. Die Einhausung wird dabei von dem Bodenverkleidungsteil, dem Dachverkleidungsteil sowie den Wandverkleidungsteilen der Innenverkleidung in Kombination mit dem Türverkleidungsteil gebildet.In the realization of the already mentioned drawer one will also advantageously resort to a thermoplastic material which is resistant to acids / alkalis or the like. That is, all internals or moving parts inside the envelope formed by the inner lining are also advantageously made of a resistant material, such as a thermoplastic material. In this case, the self-supporting shell formed from the individual trim parts forms in connection with the door trim part a total of an almost closed space or enclosure, which has only a (small) gap between the door trim part and the rest of the envelope. The enclosure is thereby formed by the floor covering part, the roof covering part and the wall covering parts of the interior lining in combination with the door lining part.

Im Ergebnis wird ein Schrank zur Verfügung gestellt, der sich besonders als Sicherheits-Untertischschrank eignet. Tatsächlich kann dieser Sicherheits-Untertischschrank problemlos unterhalb eines Labortisches platziert werden und dient zur Aufnahme praktisch sämtlicher im Labor benötigter Gefahrstoffe sowie von Säuren/Laugen. Zu diesem Zweck ist der erfindungsgemäße Schrank in wenigstens zwei Abteilungen, nämlich in die Gefahrstoffabteilung und die Säure-/Laugen-Abteilung unterteilt.As a result, a cabinet is provided, which is particularly suitable as a safety cupboard cabinet. In fact, this safety under counter cabinet can easily be placed underneath a laboratory bench and is used to hold virtually any hazardous substance required in the laboratory, as well as acids / alkalis. For this purpose, the cabinet according to the invention is divided into at least two departments, namely the hazardous substances department and the acid / alkaline department.

Im Rahmen der Erfindung weist lediglich die Säure-/Laugen-Abteilung eine Innenverkleidung auf. Diese Innenverkleidung formt eine nahezu geschlossene Umhüllung (Einhausung) für die in ihrem Innern bevorrateten Säuren/Laugen. Etwaige Funktionselemente des Schrankkorpus sowie der Schrankkorpus als solcher befinden sich außerhalb dieser Umhüllung, können also von im Innern entstehenden Dämpfen nicht (mehr) angegriffen werden. Ganz abgesehen davon werden solche Dämpfe selbstverständlich durch eine Absaugung durchgängig aus dem Innern entfernt.In the context of the invention, only the acid / alkaline department has an inner lining. This interior lining forms an almost closed enclosure for the acids / alkalis stored in its interior. Any functional elements of the cabinet body and the cabinet body as such are located outside of this enclosure, so can not (more) be attacked by vapors produced inside. Not to mention of course, such vapors are of course removed by an extraction from the interior.

Im Ergebnis wird die Standzeit und Lebensdauer des erfindungsgemäß ausgestalteten Schrankes gegenüber bisherigen Ausführungsformen deutlich erhöht. Das lässt sich im Kern darauf zurückführen, dass im Innern entstehende Dämpfe praktisch ausschließlich auf die Innenverkleidung aus dem diesbezüglich resistenten Kunststoffmaterial treffen. Außerdem sind etwaige Zusatzeinbauten oder Zusatzelemente im Innern dieser durch die Innenverkleidung gebildeten Hülle ebenfalls aus resistenten Materialien hergestellt bzw. mit einer Abdeckung aus einem solchen resistenten Material ausgerüstet. Dadurch wird eine lange Standzeit und Lebensdauer des solchermaßen modifizierten Schrankes bei zugleich einfachem und kostengünstigen Aufbau realisiert. Hierin sind die wesentlichen Vorteile zu sehen.As a result, the service life and life of the inventively designed cabinet compared to previous embodiments is significantly increased. In essence, this can be attributed to the fact that vapors produced inside almost exclusively strike the inner lining of the plastic material that is resistant in this respect. In addition, any additional components or additional elements inside this shell formed by the inner lining are also made of resistant materials or equipped with a cover of such a resistant material. As a result, a long service life and life of the thus modified cabinet is realized at the same time simple and inexpensive construction. Here are the main benefits.

Gegenstand der Erfindung ist auch die Verwendung einer aus mehreren Verkleidungsteilen aus Kunststoff aufgebauten sowie wenigstens teilweise selbsttragenden Innenverkleidung. Diese Innenverkleidung wird zur ganzen oder teilweisen Bedeckung des Inneren des Schrankkorpus eingesetzt. Der Schrankkorpus selbst ist Bestandteil des fraglichen Schrankes, insbesondere des Sicherheitsschrankes. Zu diesem Zweck ist der Schrankkorpus mit zumindest einer an den Schrankkorpus angelenkten Tür ausgerüstet. Außerdem verfügt der Schrank, insbesondere Sicherheitsschrank über wenigstens einen derartigen Schrankkorpus. Besonders vorteilhaft kann es sich bei dem Sicherheitsschrank um einen Sicherheits-Untertischschrank handeln.The invention is also the use of a built-up of several trim parts made of plastic and at least partially self-supporting interior trim. This inner lining is used to cover all or part of the interior of the cabinet body. The cabinet body itself is part of the cabinet in question, in particular the safety cabinet. For this purpose, the cabinet body is equipped with at least one door hinged to the cabinet body. In addition, the cabinet, in particular safety cabinet has at least one such cabinet body. Particularly advantageously, it may be in the security cabinet to a security cupboard.

Im Folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert. Die einzige Figur zeigt einen erfindungsgemäßen Schrank schematisch.In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment. The single figure shows a cabinet according to the invention schematically.

In der Figur erkennt man eine Absaughaube 1, die sich oberhalb eines Labortisches 2 erstreckt. Unter dem Labortisch 2 ist ein Untertischschrank 3 angeordnet, der im Rahmen des gezeigten Beispiels als Sicherheits-Untertischschrank 3 ausgestaltet ist. Der Sicherheits-Untertischschrank 3 setzt sich in seinem grundsätzlichen Aufbau aus einem Schrankkorpus 4 sowie zwei an den Schrankkorpus 4 angelenkten Türen 5 zusammen. Bei den Türen 5 handelt es sich nicht einschränkend um Drehflügeltüren 5.In the figure, one can see a suction hood 1, which extends above a laboratory table 2. Below the laboratory table 2, a table cupboard 3 is arranged, which is designed in the context of the example shown as a safety cupboard cabinet 3. The safety cabinet 3 is composed in its basic structure of a cabinet body 4 and two hinged to the cabinet body 4 doors 5 together. The doors 5 are not limited to swing doors 5.

Außerdem erkennt man, dass der Schrankkorpus 4 wenigstens zweigeteilt ist. Tatsächlich setzt sich der Schrankkorpus 4 aus einer Gefahrstoffabteilung 4a und einer Säure-/Laugen-Abteilung 4b zusammen.In addition, it can be seen that the cabinet body 4 is at least two parts. In fact, the cabinet body 4 is composed of a hazardous substances department 4a and an acid / alkaline department 4b.

Von besonderer Bedeutung ist der Umstand, dass der Schrankkorpus 4 mit einer Innenverkleidung 6 ausgerüstet ist. Die Innenverkleidung 6 bedeckt das Innere des Schrankkorpus 4 ganz oder teilweise und ist unabhängig vom Schrankkorpus 4 ausgelegt. Hiermit meint die Erfindung, dass die Innenverkleidung 6 einen vom Schrankkorpus 4 unabhängigen Raumkörper bildet, der im Innern des Schrankkorpus 4 realisiert werden kann oder eben nicht. Im Rahmen des Ausführungsbeispiels ist lediglich die Säure-/Laugen-Abteilung 4b mit der Innenverkleidung 6 ausgerüstet. Die Innenverkleidung 6 ist selbsttragend ausgelegt, wie dies einleitend bereits beschrieben wurde.Of particular importance is the fact that the cabinet body 4 is equipped with an interior trim 6. The inner lining 6 covers the interior of the cabinet body 4 in whole or in part and is designed independently of the cabinet body 4. Hereby, the invention means that the inner lining 6 forms a body independent of the cabinet body 4, which can be realized in the interior of the cabinet body 4 or not. In the context of the embodiment, only the acid / alkaline department 4 b is equipped with the inner lining 6. The inner lining 6 is designed self-supporting, as has already been described in the introduction.

Anhand der Darstellung wird deutlich, dass die Innenverkleidung 6 mehrteilig ausgestaltet ist. Tatsächlich finden sich ein Bodenverkleidungsteil 6a, ein Dachverkleidungsteil 6b sowie mehrere Wandverkleidungsteile 6c. Die einzelnen Verkleidungsteile 6a, 6b, 6c können teilweise gegeneinander fixiert sein und formen zusammengenommen eine selbsttragende Hülle 6a, 6b, 6c, also einen zur Tür 5 hin offenen Quader. Im Rahmen des Ausführungsbeispiels stehen die einzelnen Verkleidungsteile 6a, 6b, 6c aufeinander. Etwaige zwischen den einzelnen Verkleidungsteilen 6a, 6b, 6c verbleibende Fugen werden versiegelt.From the illustration it is clear that the inner lining 6 is designed in several parts. In fact, there are a floor covering part 6a, a roof covering part 6b and a plurality of wall covering parts 6c. The individual covering parts 6a, 6b, 6c can be partially fixed against each other and together form a self-supporting shell 6a, 6b, 6c, ie a cuboid open towards the door 5. In the context of the embodiment are the individual trim parts 6a, 6b, 6c on each other. Any remaining joints between the individual covering parts 6a, 6b, 6c are sealed.

Im Rahmen des Beispiels sind die einzelnen Verkleidungsteile 6a, 6b, 6c mit dem Schrankkorpus 4 verbunden, und zwar beispielsweise lösbar. Dabei kann das jeweilige Verkleidungsteil 6a, 6b, 6c adhäsiv mit dem Schrankkorpus 4 verbunden werden. Im Allgemeinen wird man hier jedoch auf Befestigungsmittel aus Kunststoff zurückgreifen, um die einzelnen Verkleidungsteile 6a, 6b, 6c gegenüber dem Schrankkorpus 4 in einer gewünschten Position zu halten. Bei diesen Befestigungsmitteln aus Kunststoff handelt es sich nicht einschränkend um Kunststoffnägel, die mit einem Kopf und einem Federschaft ausgerüstet sind. Mit Hilfe dieses Federschaftes lässt sich der jeweilige Kunststoffnagel in einer Bohrung im Schrankkorpus 4 lösbar verankern und sorgt infolge dessen für eine zugleich lösbare und positionsgenaue Fixierung der einzelnen Verkleidungsteile 6a, 6b, 6c gegenüber dem Schrankkorpus 4. Das ist selbstverständlich nicht zwingend zu verstehen.In the context of the example, the individual covering parts 6a, 6b, 6c are connected to the cabinet body 4, for example detachably. In this case, the respective trim part 6a, 6b, 6c can be adhesively connected to the cabinet body 4. In general, however, one will fall back here on plastic fasteners to keep the individual trim parts 6a, 6b, 6c relative to the cabinet body 4 in a desired position. These plastic fasteners are not limited to plastic nails, which are equipped with a head and a spring shaft. With the help of this spring shaft, the respective plastic nail can be releasably anchored in a bore in the cabinet body 4 and as a result ensures a simultaneously releasable and positionally accurate fixation of the individual covering parts 6a, 6b, 6c relative to the cabinet body 4. This is of course not necessarily understand.

In jedem Fall bilden die einzelnen Verkleidungsteile 6a, 6b, 6c die selbsttragende Hülle 6a, 6b, 6c, die unabhängig vom Schrankkorpus 4 ausgelegt ist. Die einzelnen Verkleidungsteile 6a, 6b, 6c sind aus Kunststoff, insbesondere einem thermoplastischen Kunststoff wie Polyethylen oder Polypropylen, gefertigt. Zu der Verkleidung 6 gehört auch ein Türverkleidungsteil 6d, welches innenseitig der Tür 5 an diese angebracht ist. Die sämtlichen Verkleidungsteile 6a, 6b, 6c, 6d formen zusammengenommen einen praktisch geschlossenen Raum, die Einhausung 6a, 6b, 6c, 6d welche in ihrem Innern Säure- und/oder Laugenvorräte aufnimmt. Dabei schließen die einzelnen Verkleidungsteile 6a, 6b, 6c, 6d jeweils nahezu fugenfrei aneinander an. Sofern etwaige Fugen verbleiben, werden diese ebenfalls mit Kunststoff versiegelt.In any case, the individual covering parts 6a, 6b, 6c form the self-supporting shell 6a, 6b, 6c, which is designed independently of the cabinet body 4. The individual trim parts 6a, 6b, 6c are made of plastic, in particular a thermoplastic such as polyethylene or polypropylene. To the panel 6 also includes a door trim part 6d, which is inside the door 5 attached thereto. The total covering parts 6a, 6b, 6c, 6d taken together form a practically closed space, the housing 6a, 6b, 6c, 6d which receives in its interior acid and / or alkali supplies. The individual trim parts 6a, 6b, 6c, 6d each close to each other almost without joints. If any joints remain, they are also sealed with plastic.

Die einzelnen Verkleidungsteile 6a, 6b, 6c, 6d formen die insgesamt nahezu geschlossene Einhausung 6a, 6b, 6c, 6d, die lediglich randseitig des Türverkleidungsteils 6d einen geringfügigen Spalt aufweist. Außerhalb dieser Einhausung 6a, 6b, 6c, 6d sind Funktionselemente des Schrankes angeordnet, beispielsweise ein Schloss für die als Drehflügeltür 5 ausgestaltete Tür 5, eine Handhabe für die Tür 5, Scharniere für die Tür 5 etc. Auf diese Weise werden diese Funktionselemente nicht von sich etwaig im Innern der aus den Verkleidungsteilen 6a, 6b, 6c, 6d geformten Einhausung 6a, 6b, 6c, 6d gebildeten Säure-/Laugendämpfen angegriffen. Dadurch ist der dargestellte Schrank mit einer hohen Lebensdauer und einwandfreien Funktionalität bei zugleich geringen Kosten ausgerüstet.The individual trim parts 6a, 6b, 6c, 6d form the overall almost closed enclosure 6a, 6b, 6c, 6d, which has only a slight gap at the edge edge of the door trim part 6d. Outside this housing 6a, 6b, 6c, 6d functional elements of the cabinet are arranged, for example, a lock for the door 5 designed as a swing door 5, a handle for the door 5, hinges for the door 5, etc. In this way, these functional elements are not of Any attacked in the interior of the formed from the trim parts 6a, 6b, 6c, 6d housing 6a, 6b, 6c, 6d acid / Laugendämpfen attacked. As a result, the illustrated cabinet is equipped with a long service life and perfect functionality at a low cost.

Hierzu trägt ergänzend bei, dass etwaige Innenanbauten im Innern der Innenverkleidung 6 ebenfalls aus einem resistenten Werkstoff, im vorliegenden Fall erneut einem thermoplastischen Kunststoff, hergestellt sind. Zu diesen Elementen mögen ein oder mehrere Schienenführungen 7, 7' gehören, die ebenfalls aus Polyethylen oder Polypropylen hergestellt sind. An oder auf den besagten Schienenführungen 7, 7' kann eine Schublade aus thermoplastischem Kunststoff geführt werden. Zur Anbringung der Schienenführung 7, 7' an dem Schrankkorpus 4 mögen Schrauben dienen, deren Schraubenköpfe mit Kunststoffkappen ebenfalls aus thermoplastischem Kunststoff abgedeckt sind, um den Säuredämpfen keine Angriffsfläche zu bieten.This is supplemented by the fact that any interior fittings in the interior of the inner lining 6 are also made of a resistant material, again a thermoplastic in the present case. These elements may include one or more rail guides 7, 7 'which are also made of polyethylene or polypropylene. On or on the said rail guides 7, 7 ', a drawer made of thermoplastic material can be performed. To attach the rail guide 7, 7 'on the cabinet body 4 may serve screws whose screw heads are covered with plastic caps also made of thermoplastic material to provide the acid vapors no attack surface.

Die jeweilige Schienenführung 7, 7' ist zweiteilig gestaltet und setzt sich aus einer Rollenleiste 7 und einer Schubleiste 7' zusammen. Auf der Rollenleiste 7 werden nicht ausdrücklich dargestellte Rollen zur Führung der Schublade geführt. Die Schubleiste 7' sorgt für die Positionierung der Schublade.The respective rail guide 7, 7 'is designed in two parts and consists of a roller bar 7 and a push bar 7' together. On the roller bar 7 not shown rollers are guided to guide the drawer. The sliding strip 7 'ensures the positioning of the drawer.

Die einzelnen Verkleidungsteile 6a, 6b, 6c, 6d können insgesamt oder nur teilweise mit dem Schrankkorpus 4 respektive der Tür 5 verbunden werden. Denn bei diesem Vorgang werden gegebenenfalls und automatisch Schlitze 8 gebildet, die zur Führung und Aufnahme der übrigen Verkleidungsteile 6a, 6b, 6c, 6d dienen. Im gezeigten Beispiel formen die Wandverkleidungsteile 6c in Verbindung mit dem Schrankkorpus 4 solche Schlitze 8, die vorliegend zur Aufnahme einerseits des Dachverkleidungsteils 6b und andererseits des Bodenverkleidungsteils 6a dienen.The individual trim parts 6a, 6b, 6c, 6d can be connected in whole or only partially with the cabinet body 4 and the door 5, respectively. For in this process, if necessary and automatically slots 8 are formed, which serve to guide and receiving the remaining trim parts 6a, 6b, 6c, 6d. In the example shown, the wall covering parts 6c in conjunction with the cabinet body 4 form such slots 8, which in the present case serve to receive on the one hand the roof covering part 6b and on the other hand the floor covering part 6a.

Im Ausführungsbeispiel stehen die einzelnen Verkleidungsteile 6a, 6b, 6c im Innern des Schrankkorpus 4 aufeinander. Das Türverkleidungsteil 6d ist demgegenüber an die Tür 5 angeschlossen und kann naturgemäß mit den übrigen Verkleidungsteilen 6a, 6b, 6c in der beschriebenen Weise (aufeinander stehend) nicht wechselwirken. Man erkannt, dass die seitlichen Wandverkleidungsteile 6c mit jeweils nach außen weisenden Abkantungen 9 im Bereich einer der Tür 5 zugewandten Öffnung des Schrankkorpus 4 ausgerüstet sind. Zu diesen Abkantungen 9 der beiden seitlichen Wandverkleidungsteile 6c korrespondieren frontseitige Seitennasen 10 an einerseits dem Bodenverkleidungsteil 6a und andererseits dem Dachverkleidungsteil 6b.In the exemplary embodiment, the individual covering parts 6a, 6b, 6c are in the interior of the cabinet body 4 to each other. By contrast, the door trim part 6d is connected to the door 5 and, naturally, can not interact with the other trim parts 6a, 6b, 6c in the manner described (standing on one another). It is recognized that the lateral wall covering parts 6c are equipped in each case with outwardly directed folds 9 in the region of an opening of the cabinet body 4 facing the door 5. Corresponding to these folds 9 of the two lateral wall covering parts 6c, front side lugs 10 correspond on the one hand to the floor covering part 6a and on the other hand to the roof covering part 6b.

In eingebautem Zustand dienen die Abkantungen 9 der beiden seitlichen Wandverkleidungsteile 6c als gleichsam Anschläge für das Bodenverkleidungsteil 6a und das Dachverkleidungsteil 6b. Denn die beiden letztgenannten Verkleidungsteile 6a, 6b lassen sich nur soweit in den Schrankkorpus 4 bei zuvor montierten seitlichen Wandverkleidungsteilen 6c und hinterem Wandverkleidungsteil 6c einführen, bis die Seitennasen 10 an den Abkantungen 9 anliegen. Auf diese Weise stehen sowohl das Bodenverkleidungsteil 6a als auch das Deckenverkleidungsteil 6b gegenüber der durch die jeweilige Abkantung 9 definierten Vorderkante der seitlichen Wandverkleidungsteile 6c über. Dieser Überstand wird letztlich durch die Breite der Seitennasen 10 in Einschubrichtung definiert und sorgt dafür, dass sowohl das Bodenverkleidungsteil 6a als auch das Deckenverkleidungsteil 6b im Bereich dieses Überstandes das Türverkleidungsteil 6d bei geschlossener Tür 5 übergreifen und auch übergreifen können.In the installed state, the folds 9 of the two lateral wall covering parts 6c serve as stops for the floor covering part 6a and the roof covering part 6b. For the two last-mentioned covering parts 6a, 6b can only be inserted as far into the cabinet body 4 with previously mounted lateral wall covering parts 6c and rear wall covering part 6c until the side lugs 10 rest against the folds 9. In this way, both the floor covering part 6a and the ceiling covering part 6b are opposite to the front edge of the lateral wall covering parts 6c defined by the respective fold 9. This projection is ultimately defined by the width of the side lugs 10 in the insertion direction and ensures that both the Bodenverkleidungsteil 6a and the ceiling trim part 6b in the region of this supernatant over the door trim part 6d with the door closed 5 overlap and can also overlap.
