Description
Bei "Staubschutzmasken, mag es sich um Volloder' Halbmasken handeln, verwendet man als Filtermaterial zur Herstellung des Maskenkörpers oder der Filtereinsätze je nach-Ausbildung der Maske Schwammgummi wegen seiner großen Porosität und Staubaufnahme. Zudem kann die Reinigung der Masken in sehr einfacher Weise durch Ausklopfen, Auswaschen oder Auskochen erfolgen. Es hat sich jedoch gezeigt, daß die Porosität des Schwammgummis ungleichmäßig ist, so daß solche Masken einen großen Atemwiderstand ergeben und bei längerer Benutzung oder schwerer Arbeit lästig empfunden werden.In the case of "dust protection masks, whether they be full or half masks, is used as a filter material for the manufacture of the mask body or the filter inserts Depending on the training of the mask, sponge rubber because of its high porosity and dust absorption. In addition, the masks can be cleaned very easily by knocking them out or washing them out or boil out. However, it has been shown that the porosity of the sponge rubber is uneven, so that such masks give a great breathing resistance and are annoying during prolonged use or hard work.
Gemäß der Erfindung wird dieser Nachteil beseitigt, indem als Filtermaterial der besonders feinporige Schaumgummi verwendet wird.According to the invention, this disadvantage is eliminated by using as a filter material the particularly fine-pored foam rubber is used.
Dieses Material besitzt Vorzüge, die es gerade für den vorliegenden Zweck besonders geeignet erscheinen lassen. Schaumgummi ist spezifisch leichter als Schwammgummi. Seine an sich kleineren, aber zahlreichen Poren weisen feinste Verästelungen auf, so daß nicht nur-grober, sondern auch ganz feiner Staub zurückgehalten wird. Die Wandungen der Poren sind infolge ihrer geringen Abmessungen hinreichend steif, so daß sie beim Atmen praktisch nicht verformt werden und somit die feinen Poren dauernd frei bleiben.This material has advantages that it just makes for the present Make the purpose seem particularly appropriate. Foam rubber is specifically lighter as a sponge rubber. Its smaller but numerous pores show the finest Branches on, so that not only coarse but also very fine dust is retained will. The walls of the pores are sufficient due to their small dimensions stiff, so that they are practically not deformed when breathing, and thus the fine ones Pores remain free all the time.
Infolge seiner Struktur ist Schaumgummi erheblich widerstandsfähiger und reißfester als Schwammgummi. Der Werkstoff ist mit rauher oder glatter Außenhaut gleich gut beatembar.Due to its structure, foam rubber is considerably more resistant and more tear-resistant than sponge rubber. The material has a rough or smooth outer skin equally easy to ventilate.
Schaumgummi kann leicht in Platten oder Formteilen hergestellt werden.Foam rubber can easily be made into sheets or molded parts.
Gemäß der Erfindung werden aus solchem Schaumgummi Halb- oder Vollmasken für Staubschutzzwecke in den verschiedensten Ausführungen hergestellt, indem z. B. der Maskenkörper aus-dem Schaumgummi unmittelbar als Formteil in der Gestalt der fertigen Maske erzeugt wird. Statt dessen kann der Maskenkörper auch aus vulkanisierten Schaumgummiplatten als ebener Zuschnitt hergestellt und durch Zusammenbiegen und Verkleben an den Stoßstellen in eine geeignete, ein gutes Anliegen sichernde Form gebracht werden.According to the invention, half or full masks are made from such foam rubber Manufactured for dust protection purposes in a wide variety of designs by z. B. the mask body from the foam rubber directly as a molded part in the shape the finished mask is generated. Instead, the mask body can also be made of vulcanized Foam rubber sheets produced as a flat cut and by bending and Gluing at the joints in a suitable form that ensures a good concern to be brought.
Bei Halbmasken können Filterpackungen. als Filterscheiben oder Formteile als Wallfilter, Ringfilter wie die bekannten Papierfilter, aus Schaumgummi hergestellt werden.Filter packs can be used for half masks. as filter discs or molded parts as a wall filter, ring filter like the well-known paper filter, made of foam rubber will.
Ebenso können Vollmasken mit einem Maskenkörper aus Schaumgummi hergestellt werden, die die üblichen Augenglasfassungen, einen besonderen Dichtrahmen und gegebenenfalls ein Ausatemventil aufweisen. Die Zeichnung veranschaulicht ein Ausführungsbeispiel des Erfindungsgegenstandes in den Fig. i bis 3 in einer Ansicht in das Innere einer Halbmaske in -einem Längsschnitt und in einem Querschnitt.Full face masks with a mask body made of foam rubber can also be produced the usual eyeglass frames, a special sealing frame and, if necessary have an exhalation valve. The drawing illustrates an embodiment of the subject matter of the invention in FIGS. i to 3 in a view into the interior of a Half mask in a longitudinal section and in a cross section.
Der muldenförmige Maskenkörper i mit den hochgebogenen Rändern 2 ist als einteiliges Formstück aus Schaumgummi in der endgültigen Gestalt der Maske hergestellt. An den beiden Seitenrändern 2 ist die Bänderung 3 in bekannter Weise befestigt.The trough-shaped mask body i with the upturned edges 2 is produced as a one-piece molded piece from foam rubber in the final shape of the mask. The strap 3 is attached in a known manner to the two side edges 2.
Statt dessen könnte die Maske aus einer Platte als ebener Zuschnitt in der eingangs angedeuteten Weise hergestellt sein.Instead, the mask could be made from a plate as a flat blank be made in the manner indicated at the beginning.
Die Herstellung von Vollmasken erfolgt in ähnlicher Weise und bedarf keiner weiteren Erläuterung.-The production of full face masks takes place in a similar manner and requires no further explanation.
