Description

Totmann-Einrichtung für elektrisch angetriebene Transportvorrichtungen; insbesondere für Bahnfahrzeuge Bei elektrisch angetriebenen Transportvorrichtungen, z. B. Kränen, Traversen und besonders Eisenbahnfahrzeugen mit Einmannbedienung, ist es wichtig, daß der Führer sich ziemlich frei bewegen kann, ohne den Handgriff des Steuerschalters zu verlassen. Mit dem Handgriff ist gewöhnlich auch eine Abschaltvorrichtung verbunden, die von der Hand des Führers niedergedrückt werden muß, da andernfalls ein Abschalten des Stromes, gegebenenfalls in Verbindung mit einer Bremsung, stattfindet. Bei Steuerschaltern der bisher üblichen Ausführung, bei denen die Hand rund um die Achse des Schalters @herumgeführt wird, hat diese Anordnung die freie Bewegung des Führers stark begrenzt, so daß er z. B: bei Eisenbahnfahrzeugen während der Rangierbewegungen Schwierigkeiten hat, gleichzeitig mit dem Handhaben des Steuerschalters durch das Seitenfenster nach den Signalen zu sehen.Dead man's device for electrically powered transport devices; especially for rail vehicles For electrically powered transport devices, z. B. cranes, trusses and especially railway vehicles with one-man operation, it is important that the guide can move fairly freely without the handgrip of the control switch. With the handle there is usually also a shutdown device which must be depressed by the hand of the leader, otherwise the current is switched off, possibly in connection with braking. In the case of control switches of the previously usual design, where the hand around the Axis of the switch @ is passed around, this arrangement has the free movement of the Leader severely limited, so that he z. B: in the case of railway vehicles during shunting movements Has difficulties simultaneously with manipulating the control switch through the Side window to see the signals.

Gemäß der Erfindung ist das mit dem Handgriff verbundene Druckorgan, das beim Loslassen die Abschaltung des Stromes und gegebenenfalls die Bremsung bewirkt, um die Achse des als Rad ausgebildeten Handgriffes frei beweglich. Hierdurch erhält der Führer eine größere Möglichkeit, sich ohne Loslassen weder des genannten Druckorgans noch des Handgriffes zu bewegen.According to the invention, the pressure member connected to the handle is which, when released, causes the power to be switched off and, if necessary, the braking, freely movable around the axis of the handle, which is designed as a wheel. This gets The leader has a greater opportunity to feel without letting go of neither the said pressure organ to move the handle.

Eine Ausführungsform der Erfindung ist in der Zeichnung in senkrechtem Schnitt in Abb. z und in Aufsicht in Abb. 2 dargestellt.An embodiment of the invention is shown in the drawing in the vertical Section in Fig. Z and shown in plan view in Fig. 2.

Der Oberteil des Schaltergehäuses z ist in dünneren Linien als die übrigen eingezeichnet. Auf der durch das Gehäuse nach oben ragenden Schalterachse 2 sitzt ein Handgriff 3 in Gestalt eines Rades. Das Rad ist mit einem mittleren Ansatz q. versehen, um den ein Ring 5 mit einer Schutzkappe 6 auf Kugellagern drehbar ist. In der Schutzkappe sind zwei Hebel 7, 8 gelagert, deren einer, 7, mit seinem äußeren Ende in der Nähe des Radumfanges liegt und dort ein an den Umfang entlanggehendes Querstück-9 hat, das durch die Hand des Führers gegen das Rad gedrückt werden kann. Bei diesem Niederdrücken wirkt der zweite, mit dem ersten gekuppelte Hebel mit seinem inneren Ende auf einen Stift 1o, der das Ende der Schalterachse 2 durchsetzt und innerhalb des Schalters auf eine Abschaltvorrichtung wirkt, die bekannter Art sein kann und deshalb nicht dargestellt ist. Die Kappe 6 schützt das Kugellager, die Lager und Eingriffstellen des Hebelgetriebes. Sie bildet gleichzeitig einen Schutz für die Hände des Führers bei der Steuerung, wenn er seine Aufmerksamkeit auf etwas anderes richten muß.The upper part of the switch housing z is drawn in thinner lines than the rest. A handle 3 in the form of a wheel is seated on the switch shaft 2 protruding upward through the housing. The wheel has a middle approach q. provided around which a ring 5 with a protective cap 6 is rotatable on ball bearings. Two levers 7, 8 are mounted in the protective cap, one of which, 7, has its outer end near the circumference of the wheel and there has a cross piece 9 that extends along the circumference and can be pressed against the wheel by the hand of the driver . During this depression, the inner end of the second lever, coupled to the first, acts on a pin 1o, which passes through the end of the switch axis 2 and acts on a disconnection device within the switch, which can be of a known type and is therefore not shown. The cap 6 protects the ball bearing, the bearings and points of engagement of the lever mechanism. At the same time it forms a protection for the driver's hands when steering, if he has to direct his attention to something else.
