Description
Im Eisenbahnsicherungswe.sen werden bei Schaltwerken, z. B. für Ablaufanlagen, Sperrvorrichtungen vorgesehen, die so,eingerichtet sind, daß beim Drücken einer Taste mehrere oder alle anderen Tasten gesperrt weiden. Dies wird bewirkt dadurch, daß man unterhalb der Tasten Schieber oder Reihen von Kugeln anordnet, die beim Drücken einer Taste verschoben werden und 'dadurch in eine Lage kommen, in der das Niederdrücken anderer Tasten unmöglich gemacht wird. Hierbei war man bezüglich des Ab Standes der Tasten beschränkt, dadurch, 'daß durch die Taste nicht nur die Sperrvorrichtung betätigt wird, sondern außerdem durch die von der Taste betätigte Achse auch noch Kontakte geschlossen werden. Die Erfindung beruht nun auf der Erkenntnis, daß es möglich ist, von mehreren Seiten auf den Schieber bzw. die zur Sperrung dienende Kugel·- reihe einzuwirken, so daß man die Tasten senkrecht zur Tastenreihe verschieben bzw. , staffeln kann. Hierbei ist dann die Kontaktanordnung einer Taste nicht mehr derjenigen der benachbarten Taste im Wege, und man kann gleichzeitig einen geringeren Abstand der Tasten voneinander bewirken.In railway safety systems, switchgear, e.g. B. for drainage systems, locking devices provided, which are set up so that when a key is pressed several or all other keys are locked. This is done by underneath the keys arranges sliders or rows of balls, which when you press one Key are moved and 'thereby come into a position in which the depressing of others Keys is made impossible. Here one was limited with regard to the position of the keys, because of the Button is not only operated by the locking device, but also by the actuated axis, contacts are also closed. The invention is based now based on the knowledge that it is possible to press the slide from several sides or the row of balls used for locking, so that you can press the buttons can move or stagger perpendicular to the row of keys. Here then is the contact arrangement one key is no longer in the way of that of the adjacent key, and man can also cause the keys to be closer together.
Der Erfindungsgegenstand ist in den Figuren beispielsweise veranschaulicht.The subject matter of the invention is illustrated in the figures, for example.
Aus Fig. i ist ersichtlich, wie man die Tasten anordnen kann. Durch die Taste 1 wird über die Stange 2 beim Niederdrücken eine Verschiebung der Kugeln 3 in der Pfeilrichtung entgegen einer Spiralfeder 4 bewirkt.From Fig. I it can be seen how the keys can be arranged. With button 1 a displacement of the balls 3 in the direction of the arrow via the rod 2 when depressed against a spiral spring 4 causes.
Nach dem Zusammendrücken der Feder sind die Kugeln festgelegt. Würde man eine zweite Taste 5 drücken wollen, so würde diese gegen die festliegende Kugel 6 stoßen und also nicht gedrückt werden können. Hierdurch erfolgt in bekannter Weise die Sperrung.After compressing the spring, the balls are fixed. Would you get a second Want to press button 5, it would hit the fixed ball 6 and so cannot be pressed. This results in the blocking in a known manner.
Auch das gleichzeitige Drücken zweier Tasten wird hierdurch verhindert. Hier ist nun der Abstand« zwischen zwei benachbarten Tasten gegeben durch den Platz, den die Kontaktanordnungen 7,8 benötigen, die 4^ gleichzeitig beim Verschieben einer der Stangen 2 bzw. 9 betätigt werden. Eine engere Anordnung der Tasten ergibt sich nun, wenn man eine weitere Reihe von Tasten vorsieht, die parallel zu der Reihe I liegt, in welcher die Tasten i, 5 angeordnet sind. Beispielsweise kann eine weitere Taste 10 einer Reihe IV von unten her über eine Stange 11 auf die Kugelreihe 3, 6 einwirken.This also prevents two buttons from being pressed at the same time. Here, the distance "is now placed between two adjacent keys by the space occupied by the contact arrangements require 7.8, the 4 ^ are the same when moving one of the rods 2 or actuated. 9 A closer arrangement of the keys results if a further row of keys is provided, which is parallel to the row I in which the keys i, 5 are arranged. For example, a further button 10 of a row IV can act on the row of balls 3, 6 from below via a rod 11.
Man kann auch mehrere Reihen (I, II, III, IV) von Tasten vorsehen, wie aus Fig. 2 ersichtlich. In jedem Fall wird durch Niederdrücken einer der Tasten bewirkt, daß alle anderen gesperrt werden, gleich in welcher Reihe sie liegen, und es wird auch das gleichzeitige Drücken zweier Tasten verhindert.It is also possible to provide several rows (I, II, III, IV) of keys, as shown in FIG. 2 evident. In any case, by pressing down one of the buttons causes all others to be locked, regardless of which one They lie in a row, and it also prevents two buttons from being pressed at the same time.
In derselben Weise läßt sich die Erfindung auch verwirklichen, wenn an Stelle der Kugeln ein Schieber tritt. Der Schieber wird dann auf.'verschiedenen Seiten mit Schrägflächen versehen, die zum Verschieben der Schieberstange durch Tasten mehrerer Reihen dienen.In the same way, the invention can also be implemented if instead of the balls a slider kicks. The slide is then on different sides with sloping surfaces provided, which is used to move the push rod by touching several rows to serve.
