Description
Die Erfindung bezieht sieh auf ein optisches Rufzeichen für Gaststätten., dessen Anzeigescheibe durch Tastendruck eingestellt wird. Das durch den Tastendruck bewegte Antriebswerk ist erfindungsgemäß derart ausgebildet, daß abwechselnd bei einem Tastendruck die Anzeigescheibe hochgestellt (sichtbar wird) und beim nächsten Druck auf dieselbe Taste die Scheibe wieder abwärts bewegt (unsichtbar) wird.The invention relates to an optical call sign for restaurants., Whose Indicator disc is set by pressing a button. That moved by the push of a button Drive mechanism is designed according to the invention in such a way that alternately when a button is pressed the indicator disc is raised (becomes visible) and the next time it is pressed Button moves the disc downwards again (invisible).
Die Zeichnung veranschaulicht eine derartige Vorrichtung des Erfindungsgegenstandes, und zwar zeigt Abb. ι die äußere Gesamtansicht mit einem darunter befindlichen Aschenbecher, Abb. 2 das Antriebswerk des Rufzeichens in Draufsicht in der Weise, daß die schwarzen Linien die Ruhestellung des Triebwerkes, dagegen die strichpunktierten dessen Arbeitsstellung angeben.The drawing illustrates such a device of the subject matter of the invention, namely, Fig. ι shows the external overall view with one below Ashtray, Fig. 2, the drive mechanism of the call sign in a plan view in such a way that the black lines the idle position of the engine, on the other hand the dash-dotted lines indicate its working position.
Die Bedienung des Rufzeichens erfolgt in folgender Weise:The call sign is operated in the following way:
Durch Druck auf eine Taste α werden die Hebel b und c des Antriebswerkes derart bewegt, daß die am Hebel c beweglich angebrachte Schaltklinke d, welche mit ihrer Spitze vor einem der Zähne des Triebrades e liegt, dieses und das mit demselben fest verbundene Zahnrad f entsprechend herumdrückt, und zwar um eine sechstel Umdrehung.By pressing a key α, the levers b and c of the drive mechanism are moved in such a way that the pawl d movably attached to the lever c , which is located with its tip in front of one of the teeth of the drive wheel e , this and the gearwheel f connected to it accordingly around a sixth of a turn.
Da das Zahnrad/ mit seinem äußeren Umfange in ein Zahnrad g eingreift, wird dieses ebenfalls mitgedreht. Die Bewegung des Zahnrades g beträgt bei jedem Tastendruck eine halbe Umdrehung. Die Verbindung zum Heben und Senken der Ruf scheibe i wird vom Rade g aus - durch den Hebel h hergestellt, der exzenterartig am Rade g angreift. Durch einen Tastendruck wird das Triebwerk derart in Bewegung gesetzt, daß die Anzeigescheibe i entweder nach oben oder nach unten geschoben wird. Um die Taste α nach jedem Druck wieder in die ursprüngliche Lage zu bringen, ist unter derselben die Feder k an-[ gebracht. Die Rückbewegung der Taste α mit den Hebeln b und c verursacht keine Weiterschaltung der Räder e und g, weil die Klinke d bei der Rückbewegung jedesmal über den jeweiligen Zahn des Triebrades e hinweggleitet. Dadurch wird die Anzeigescheibe i in der jeweiligen Stellung festgehalten. Since the gearwheel / engages with its outer circumference in a gearwheel g , this is also rotated. The movement of the gear wheel g is half a turn with each key press. The connection for raising and lowering the call disk i is made from the wheel g - by the lever h , which engages the wheel g like an eccentric. By pressing a button, the engine is set in motion in such a way that the indicator disk i is pushed either up or down. In order to bring the key α back to its original position after each press, the spring k is placed under it. The return movement of the key α with the levers b and c does not cause the wheels e and g to be indexed, because the pawl d slides over the respective tooth of the drive wheel e each time during the return movement. As a result, the indicator disk i is held in the respective position.
