Abstract

The safety mechanism has a gas barrier device provided with a spring for resetting the mechanism in a feed position. Gas supply is interrupted in a triggered condition when the mechanism is closed, and stops fire when a Bunsen burner and/or a gas burner placed on a table are overturned. The gas is flowed via an opening. The gas supply is free in a non-triggered condition when the mechanism is opened.

Description

  • 1. Ich habe von meiner Mutter gehört, dass in ihrer Schulzeit einer Mitschülerin der Bunsenbrenner umgefallen und ihr Versuchsaufbau abgebrannt war, sowie fast der gesamte Chemieraum.1. I heard from my mother that in her school time a classmate the Bunsen burner had fallen down and her experimental setup was burned down, as well as almost the entire chemistry room.
  • 2. Ich überlegte mir wie man mit simplen Mitteln diesem Problem entgegenwirken kann. 2.1 Die Lösung ist simpel. Die Gaszufuhr muss mit einer Mechanik gestoppt werden. 2.2 Wie im Anhang zu sehen ist, habe ich die Luftzufuhr außen vor gelassen und nur die Gaszufuhr skizziert. 2.3 Im Bildteil 1 ist eine Übersicht des Bunsenbrenners/Gasbrenners. 2.4 Im Bildteil 2 ist skizziert wie die Gaszufuhr gestoppt wird, wenn der Bunsenbrenner/Gasbrenner nicht mehr auf einem festen Untergrund steht (z. B. Tisch). Wenn z. B. der Bunsenbrenner/Gasbrenner umgestoßen wird und umgekippt. 2.5 Im Bildteil 3 ist skizziert wie der Zustand ist, wenn der Bunsenbrenner/Gasbrenner auf einem festen Untergrund steht (z. B. einem Tisch). 2.6 Im Bildteil 4 ist in diesem Fall der Sicherheitsmechanismus/die Sicherheitsmechanik mit der Feder zu sehen. Durch das Loch fließt das Gas.2. I thought me how to counteract this problem with simple means. 2.1 The solution is simple. The gas supply must be stopped with a mechanism. 2.2 As can be seen in the appendix, I have the air supply outside left and sketched only the gas supply. 2.3 in picture part 1 is an overview Bunsen burner / gas burner. 2.4 In picture part 2 is sketched how the gas supply is stopped when the bunsen burner / gas burner no longer on a solid surface (eg table). If z. B. the Bunsen burner / gas burner is knocked over and overturned. 2.5 In the picture part 3 is sketched how the condition is, if the Bunsenbrenner / gas burner standing on a solid surface (eg a table). 2.6 In the image part 4 is in this case the security mechanism / Safety mechanism with the spring to see. The gas flows through the hole.
  • 3. Patentiert wird das Prinzip/die Mechanik, welches die Gaszufuhr des Gasbrenners schließt.3. Patented is the principle / mechanics, which is the gas supply the gas burner closes.

Claims (1)

Der Sicherheitsmechanismus/Sicherheitsmechanik eines Bunsenbrenners bzw. Gasbrenners ist gekennzeichnet durch folgende Merkmale: – Die Unterbrechung der Gaszufuhr im ausgelösten Zustand (Siehe Bild 2 – geschlossen) – Freie Gaszufuhr im nicht ausgelösten Zustand (Siehe Bild 2 – geöffnet) – Bestehend aus einer Gassperrvorrichtung (Siehe Bild 4) mit einer Mechanik (in diesem Fall eine Feder) zur Zurücksetzung bei unterbrochener Gaszufuhr – Wenn der Bunsenbrenner bzw. Gasbrenner um kippt, löst der Sicherheitsmechanismus/Sicherheitsmechanik durch Unterbrechung der Gaszufuhr aus und stoppt die Gaszufuhr. – Nachdem der Sicherheitsmechanismus/die Sicherheitsmechanik ausgelöst hat und wieder in die zu stellende Position zurückgesetzt wurde, wird wieder die Gaszufuhr freigestellt/freigegeben.The safety mechanism / safety mechanism a Bunsen burner or gas burner is characterized by the following Characteristics: - The Gas supply interruption in tripped condition (See Figure 2 - closed) - Free Gas supply in the untriggered Condition (See Figure 2 - open) - Consisting from a gas barrier device (see figure 4) with a mechanism (in this case a spring) to reset if interrupted gas supply - If the Bunsen burner or gas burner tilts around, releases the safety mechanism / safety mechanism by interrupting the gas supply and stops the gas supply. - After this the safety mechanism / safety mechanism has triggered and is reset back to the position to be put, is again the Gas supply released / released.
