Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand vorliegender Erfindung ist eine Verriegelung zur Verhütung der gleichzeitigen Bewegung zweier Hebel, von denen jeweils nur einer bewegt werden darf, z. B. bei zweiseitig aufschlagenden Thüren, bei Doppelumschaltern, Doppelhähnen an chemischen Apparaten und dergl.The present invention is a lock to prevent simultaneous Movement of two levers, of which only one may be moved at a time, e.g. B. with two-sided opening doors, double switches, double taps on chemical apparatus and the like
In der Zeichnung ist die Verriegelung an einem Doppelumschalter als Beispiel dargestellt.In the drawing, the locking on a double changeover switch is shown as an example.
In die Stromquelle α (Fig. 1 bis 3) sollen sowohl die Leitung b als auch die Leitung c und auch beide Leitungen b und c eingeschaltet werden können, aber, um einen Kurzschlufs zu vermeiden, niemals das kurze Verbindungsstück d allein. Nun ist in Wirklichkeit der Weg, den die Umschalthebel e von dem Contact f nach dem Contact g bezw. von h nach i zurücklegen, viel kleiner als die -schematischen Zeichnungen erkennen lassen, und deshalb ist es erforderlich, dafs, sobald einer der Umschalthebel seine Bewegung beginnt, die Bewegung des anderen Hebels in entgegengesetztem Sinne sofort verhindert wird. Ebenso könnte die Anordnung z. B. bei einer zweiseitig aufschlagenden Thür mit Vortheil verwendet werden.In the current source α (Fig. 1 to 3) both the line b and the line c and also both lines b and c should be able to be switched on, but to avoid a short circuit, never the short connector d alone. Now, in reality, the path that the switching lever e from the Contact f to the Contact g respectively. travel from h to i , much smaller than the schematic drawings show, and therefore it is necessary that as soon as one of the switching levers begins its movement, the movement of the other lever in the opposite direction is immediately prevented. Likewise, the arrangement could e.g. B. be used with a double-sided opening door with advantage.
Diese sofortige Verriegelung wird dadurch erreicht, dafs von jedem der Umschalthebel (Thürklinke u. s. w.) eine Stange k I nach einem Kästchen m führt, in welchem sich eine Klinke η (Fig. 4) befindet, welche die andere Stange augenblicklich an einer auf die Klinke zu gerichteten Bewegung verhindert, sobald eine Stange begonnen hat, sich in dieser Richtung zu bewegen (Fig. 5 bezw. Fig. 6).This immediate locking is achieved by the fact that from each of the switching levers (door handle, etc.) a rod k I leads to a box m in which there is a pawl η (Fig. 4), which the other rod immediately on one of the pawl directed movement prevented as soon as a rod has started to move in this direction (Fig. 5 and Fig. 6).
Das Wesentliche der Verriegelung, das Kästchen wi, die Stange k I und die Klinke η sind für jeden Verwendungszweck die gleichen, nur die Anordnung der zu bewegenden Hebel wird je nach Bedarf eine andere sein; beispielsweise müfsten die Stangen k I in dem in den Fig. 1 bis 3 angeführten Beispiele von den Hebeln e isolirt werden.The essentials of the lock, the box wi, the rod k I and the pawl η are the same for each purpose, only the arrangement of the levers to be moved will be different as required; for example, the rods k I in the examples given in FIGS. 1 to 3 would have to be isolated from the levers e.
