Beschreibung und Erläuterung zur Zusatzpatent-Description and explanation of the additional patent
und Hilfsgebrauchsmusteranmeldung Autofilterkissen mit arretierender Nadelung" Zusatz zu P 28 20 313.6 In der Hauptpatentanmeldung wird ein Filter für Autokabinen beschrieben, das aus filternden Chemisorptionsmassen besteht, die in leicht verformbare, kissenförmige Ummantelungen verpackt sind und vorzugsweise zur Arretierung und klebenden Abdichtung mit Klebestreifen versehen werden.and utility model registration car filter pads with locking Needling "Addition to P 28 20 313.6 In the main patent application a filter for Car cabins described, which consists of filtering chemisorption masses that are in easily deformable, pillow-shaped sheaths are packaged and preferably used for Locking and adhesive seal can be provided with adhesive strips.
Die Praxis hat gezeigt, daß die beschriebenen Autofilterkissen unerwünschte Schadstoffe in Autokabinen, Arbeitsschutzkabinen usw. gut abscheiden.Practice has shown that the car filter pads described are undesirable Separate pollutants well in car cabins, work safety cabins, etc.
Die erfindungsgemäße Ausbildungsform, anschmiegbare, leicht verformbare, kissenförmige Zusammensetzung mit abdichtenden Klebestreifen, ist sehr gut zu praktizieren, da die unterschiedlichsten Ausbildungsformen von Ansaugkanälen an dem anschmiegsamen Filterkissen und dem Klebestreifen gut filternd und abdichtend an den Rändern eingebracht bzw. angebracht und befestigt werden können.The embodiment according to the invention, conformable, easily deformable, pillow-shaped composition with sealing adhesive strips, is very good to practice, since the most varied of forms of intake ducts on the cuddly one Filter pad and the adhesive strip filter well and seal the edges or can be attached and fastened.
Bei starken Rüttelbewegungen, z. B. in Krankabinen oder Autokabinen, verrutschen vielfach die in dem filternden Kissenpaket eingelagerten Chemisorptionsmassen und, da grundsätzlich die Luft den Weg des geringsten Widerstandes geht, wird die Ansaugluft nicht mehr optimal gefiltert und Durchbrüche an den schwach beaufschlagten Stellen sind unvermeidbar.With strong shaking movements, z. B. in crane cabins or car cabins, The chemisorption masses stored in the filtering cushion pack often slip and, since air basically takes the path of least resistance, it becomes Intake air no longer optimally filtered and breakthroughs at the weakly pressurized Places are inevitable.
In der Praxis hat man filternde Vorrichtungen vielfach so ausgerüstet, daß die chemisorbierenden körnigen Massen entweder zu Platten miteinander verklebt werden oder aber zusammengepresst zwischen zwei Fa'tqeweben am Verrutschen gehindert werden sollen.In practice, filtering devices have often been equipped in such a way that that the chemisorbing granular masses either glued together to form plates are prevented from slipping or if they are pressed together between two Fa'tqeweben should be.
Das Aufeinanderpressen und auch das Miteinanderverkleben bringt natürlich einen erhöhten Widerstand für einen Chemisorptionsfilter und gleichzeitig wird die flexible, notwendige Anschmiegsamkeit an die verschiedensten Ansaugformen nicht mehr ermöglicht.Pressing and gluing together brings natural benefits an increased resistance for a chemisorption filter and at the same time the flexible, necessary conformability to the most diverse suction forms is not enables more.
Um nun die Nachteile der Starrheit eines Luftfilterelementes und den hohen Widerstand eines gepressten Luftfilterelementes zu beseitigen und trotzdem die körnigen chemisorbierenden Massen 1. an einem Verrutschen zu hindern, um ständig die gewollte und vorgegebene gleichmäßige Filterstärke auch bei größten Rüttelbewegungen zu halten und 2. die Flexibilität und Schmiegsamkeit an die beliebigen Ansaugkanalformen durch einfachste Abdichtung mittels Klebestreifen zu ermöglichen, wird erfindungsgemäß vorgeschlagen, ein fließartiges Material zu verwenden, das in der Fließstruktur die chemisorbierenden, vorzugsweise körnigen Massen eingelagert bekommt und mittels Nadelung zu einem plattenförmigen Kissenpaket verarbeitet wird, das durch das Vernähen der oberen und unteren sowie der dazwischen gelagerten Fließschichten die Nadelfäden die chemiabsorbierenden Körner am Verrutschen a) hindern b) die gewünschte Verformbarkeit nicht beeinträchtigen und c) eine gleichmäßige filternde Schichtdicke auch bei größerer Rüttelung garantieren.To now the disadvantages of the rigidity of an air filter element and the to eliminate the high resistance of a pressed air filter element and still To prevent the granular chemisorbent masses 1. from slipping in order to constantly the desired and specified uniform filter strength even with the greatest shaking movements to keep and 2. the flexibility and pliability to any shape of the intake duct To enable the simplest sealing by means of adhesive strips is according to the invention proposed to use a flow-like material that is in the flow structure the chemisorbent, preferably granular mass gets stored and means Needling is processed into a plate-shaped cushion package, which is sewn by sewing of the upper and lower as well as the flow layers in between the needle threads the chemically absorbent grains from slipping a) prevent b) the desired deformability do not affect and c) a uniform filtering layer thickness even with a larger one Guarantee vibration.
Weiterhin wird erfindungsgemäß vorgeschlagen, die genadelt Chemisorptions-Filtereinheit an den Rändern mit elastischer Abdichtung zu versehen, wie z. B. Weich-PVC, Weich-Gummi oder dergleichen. Durch diese elastisch abdichtende Randbewährung werden auch die Chemisorptionsteilchen im Filterpaket gehalten, die an den Rändern nicht durch eine Nadelung erfaßt und arretiert sind.Furthermore, it is proposed according to the invention, the needled chemisorption filter unit to be provided at the edges with elastic sealing, such as. B. soft PVC, soft rubber or similar. This elastic sealing edge reinforcement are also the Chemisorbent particles held in the filter pack, which at the edges are not blocked by a Needling are detected and locked.
Die beiliegende Zeichnung zeigt mit A die Vorderansicht und mit B die Draufsicht des Filters.The accompanying drawing shows with A the front view and with B the top view of the filter.
In der beiliegenden Zeichnung ist die erfindungsgemäße Ausführung dargestellt: mit 1: das plattenförmige, kissenartige Chemisorptionsfilterelement, mit 2: das fließartige Material, z. B. Filz oder dergleichen oder auch ein anderes stark luftdurchlässiges Filtermaterial, mit 3: die Chemisorptionsmassen mit 4: die arretierende erfindungsgemäße Nadelung, die die Chemisorptionsmassen zwischen dem filterartigem Material festhält, mit 5: die dichtenden Klebestreifen, die das Filterelement, entsprechend verformt, mit dem Ansaugkanal oder über dem Ansaugkanal dichtend arretieren.The embodiment according to the invention is shown in the accompanying drawing shown: with 1: the plate-shaped, pillow-like chemisorption filter element, with 2: the flow-like material, e.g. B. felt or the like or something else highly air-permeable filter material, with 3: the chemisorption masses with 4: the arresting needling according to the invention, which the chemisorption masses between the holds filter-like material, with 5: the sealing adhesive strips, which the filter element, deformed accordingly, with the intake duct or above the Lock the intake duct tightly.
Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellten und beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, einen Chemisorptionsfilter so herzustellen, daß er aus filternden stoffartigen Materialien besteht, zwischen denen Chemisorptionsmassen eingelagert sind und die gegen Verrutschen durch Nadelungen, vorzugsweise fädenartigen Charakters, gesichert sind, ohne dabei dem Filter die Flexibilität zu nehmen.Of course, the invention is not limited to the above in detail Forms of training shown and described are limited, but there are numerous Modifications possible without deviating from the basic idea, a chemisorption filter manufactured so that it consists of filtering cloth-like materials between which chemisorption materials are embedded and which prevent slipping through needling, preferably thread-like character, are secured without affecting the filter Take flexibility.
