Schutzbrille.Safety goggles.
Von einer Schutzbrille für Arbeiten in chemischen Betrieben wird verlangt, daß sie die Augen gegen sowohl von vorne als auch von den Seiten kommende Flüssigkeitsspritzer oder sprühende Festteile schützt. Um dieser Forderung nachzukommen ist es notwendig, daß die für die Belüftung des Brillenraumes benötigten Schlitze so angeordnet werden, daß die Luft nur von der hinteren Seite des Brillengestelles her eintreten kann. Erfahrungsgemäß reicht diese Art der Belüftung jedoch * nicht aus, um bei starkem Schwitzen des Brillenträgers die Klarsichtscheiben der Brille vor dem Beschlagen zu bewahren. Die hierdurch eintretende Sichtbehinderung gefährdet den Brillenträger und beeinträchtigt seine Arbeitsleistung bzw. zwingt ihn zum Abnehmen der Brille.Safety goggles for work in chemical plants are required to face both the front and the eyes also protects splashes of liquid or spraying solid parts from the sides. To meet this demand it is necessary for the ventilation of the eyeglass room required slots are arranged so that the air can only enter from the rear of the spectacle frame can. Experience has shown, however, that this type of ventilation * is not sufficient to prevent the wearer from sweating heavily To keep the transparent lenses of the glasses from fogging up. The resulting obstruction of view endangers the Wearers of glasses and impairs their work performance or forces them to take off their glasses.
Genügend widerstandsfähige Klarsichtscheiben, die auch unter erschwerten Bedingungen nicht beschlagen, sind bisher nicht beschrieben worden. Versuche, die Lufterneuerung durch ver- - besserte Luftschlitze zu beschleunigen, haben ebenfalls nicht zum Ziel geführt.Sufficiently resistant transparent panes that do not fog up even under difficult conditions are not yet available has been described. Attempts to renew the air by reducing - Accelerating improved air vents also did not lead to the goal.
Neuerungsgemäß wird nun eine Schutzbrille vorgeschlagen, bei der das Beschlagen der Klarsichtscheiben durch Einblasen von Luft oder anderen physiologisch unbedenklichen Gasen in den Brillenraum verhindert wird. Der Brillenkörper ist zu diesem Zwecke an einer oder mehreren Stellen mit Düsen versehen,According to the innovation, protective goggles are now proposed in which the fogging of the transparent panes is caused by blowing Air or other physiologically harmless gases in the Glasses space is prevented. The goggle body is provided with nozzles at one or more points for this purpose,

durch welche man das Gas so einleitet, daß der Brillenraum gleichmässig ausgespült wird. Die Menge des Gases ist dabei so zu bemessen, daß der Feuchtigkeitsgehalt des Brillenraumes nicht über den Taupunkt steigt. Ein 1- bis 10-facher vorzugsf"" weise 2- bis 4-facher Gaswechsel pro Minute genügt hierfür " auch bei starkem Schwitzen des Brillenträgers.through which the gas is introduced in such a way that the glasses space is flushed out evenly. The amount of gas is included to be dimensioned so that the moisture content of the glasses compartment does not rise above the dew point. A 1- to 10-fold preferential "" wise, 2 to 4 times gas changes per minute are sufficient for this "even if the wearer sweats heavily.
Das Spülgas kann einem unter Überdruck stehenden Behälter, der sich beispielsweise in der Tasche des Brillenträgers befindet, über ein Regelventil entnommen werden. Vorteilhafter wird jedoch, wie in der Skizze dargestellt, mittels eines Mikrogebläses (i), das am Brillengestell (2) ohne Beeinträchtigung des Sehfeldes befestigt ist, über die Düse (3) die Lufterneuerung erreicht. Das Gebläse (1) zusammen mit Motor (4) und Stromquelle (5)> welches mittels des Schalters (6) einschaltbar ist, kann ohne Schwierigkeiten in einem Zylinder (7)» λ der bei 15 nun Durchmesser nicht langer als 80 mm zu sein braucht, untergebracht werden.The purge gas can be in a pressurized container, which is for example in the pocket of the wearer of glasses, can be taken from a control valve. More advantageous is, however, as shown in the sketch, by means of a micro-fan (i), which is attached to the glasses frame (2) without impairment the field of view is fixed, the air renewal is achieved via the nozzle (3). The fan (1) together with the motor (4) and power source (5)> which can be switched on by means of the switch (6) can be no longer than 80 mm in a cylinder (7) »λ which at 15 is now diameter no longer than 80 mm needs to be accommodated.
Das Gewicht der beschriebenen Vorrichtung beträgt nur ca. 30 g> so daß für den Brillenträger keine störende Mehrbelastung auftritt. Der zum Antrieb des Mikrogebläses verwendete handelsübliche Motor nimmt bei einer Spannung von 1,5 V für den Antrieb des Gebläses ca. 15 mA auf, so daß eine ebenfalls handelsübliche Mikrostabzelle für ca. 50-stündigen Betrieb ausreicht.The weight of the device described is only approx. 30 g> so that there is no disruptive additional burden for the spectacle wearer. The commercially available one used to drive the micro-blower Motor consumes approx. 15 mA at a voltage of 1.5 V for driving the fan, so that one too Commercially available micro rod cell for approx. 50 hours of operation sufficient.
