Definitions
- the invention relates to a push button with a mechanical signal display for the circuit of a switching unit, comprising an actuating head and a housing, wherein the mechanical display is arranged in the actuating head and has at least one recess and a recognizable by the recess display area.
- Electromechanical command devices are widely used to operate and control machinery and equipment. They occur in various forms, for example as pushbuttons, toggle switches, key switches or emergency stop switches. Command devices are mounted on control panels, control panels, control cabinet doors or enclosure covers. By manually operating the command devices electrical switching state changes and thus the desired control effects are generated. Command devices are equipped as standard with a mechanical display to indicate prevailing switching states, the mechanical display optionally optionally or additionally equipped with a luminous or illuminated unit.
- Command devices are generally modular. That is, they consist of a push button, a fastening part, such as a ring nut or a mounting bracket and one or more switching elements, which are designed as normally closed or normally closed contacts.
- the actuator is usually guided from the front through a hole in the dash panel and mounted from behind by means of a fastening part.
- the switching elements are mechanically fastened with screws, snap hooks or bolts on the actuator or on the fastening part.
- the electrical connection of the switching elements to the controller via terminals.
- it is mandatory that the signal be sent through the Opening of positively-opening contacts is generated. This means that with an unconfirmed emergency stop command device, the contacts and thus the associated circuit are closed.
- the normally closed contact is interrupted by striking the emergency stop actuator, which is located in front of the control panel, and the system or machine is put into a safe state.
- the emergency stop actuator which is located in front of the control panel, and the system or machine is put into a safe state.
- the emergency stop command device is no longer functional. That is, in an emergency operation, the contacts are not opened and thus there is no elimination of the dangerous condition. This can lead to fatal damage to man and machine. Therefore, the secure connection between actuator and switching element is essential.
- the disadvantage of the prior art is that the mechanical display surface is guided over very delicate mechanical components that can easily tilt or deform due to the spatial tightness in the command device and as a consequence no longer allow a proper operation of the command device.
- the object of the present invention is to provide a push button with a mechanical signal display, which is structurally simple and allows reliable operation.
- a push button with a mechanical signal display for the circuit of a switching unit comprising an actuating head and a housing, wherein the mechanical display is arranged in the actuating head and has at least one recess and a recognizable by the recess display area.
- the invention is characterized in that sliding contours are arranged on the actuating head and on the housing, which are in operative connection with one another.
- the pushbutton according to the invention is designed structurally simple, but still so robust designed that ensures reliable operation is.
- the slide contours, which are in operative connection with one another are mounted on the outside of the housing, so that the interior of the pushbutton, which is already very limited anyway, can be used elsewhere.
- the outside attachment of the sliding contours which are arranged on the one hand on the outside of the housing, and on the other on the actuating head in a partial area which is guided over the housing, has the further advantage that even if the sliding contours are damaged, the detached part does not engage in fall inside the push button and prevent actuation of the pushbutton there.
- Another decisive advantage is that the sliding contours are structurally kept so simple that they are preferably arranged in a plurality on the housing or on the actuating head, so that even if a sliding contour damage the other sliding contours can still work properly and the pushbutton therefore not a total must be replaced.
- the housing is designed as a rosette, so as a cylindrical basic shape.
- This body has proven to be particularly advantageous for the actuation of the actuating head, since the cylindrical shape offers no edges at which the actuating head could get caught in the actuation case.
- the sliding contour is formed on the housing as a sliding web.
- This sliding web acts as a guide web and is in operative connection with the bevelled cylinder jacket part section surface of the actuating head. After actuation of the actuating head, the slanted Zylindermantelteilabitess response is then arranged between two guide webs.
- the sliding webs are arranged at preferably regular intervals around the housing. This results in several Sliding contour pairs of sliding webs and bevelled cylindrical shell section areas, which allow the pushbutton to continue to be used if one of these sliding pairs is damaged.
- the sliding contour is formed on the actuating head as a chamfered cylinder jacket part section surface. It is provided in the case of actuation that the slanted Zylindermantelteilabitess formulation slides down on an edge of a guide bar until the actuating head has arrived in the end position.
- the mechanical signal display for the status display of at least two switching states is formed. These two different switching states may be indicated by different colors, such as green and red, applied in a lid member of the actuator head which terminates in the beveled cylindrical shell portion portion.
- the sliding contours are formed from plastic. This material allows for a smooth sliding action between the beveled cylinder shell portion surfaces and the sliding webs. In addition, plastic is dimensionally stable and is not subject to major aging processes.
- the sliding contours are arranged on the outside of the housing and on the actuating head.
- the external attachment of the sliding structures results in that the interior of the pushbutton can be used elsewhere.
- sprayed plastic parts do not fall into the interior of the pushbutton, where they could oppose an actuation of the pushbutton.
- the pushbutton according to the invention is structurally simple in design, but still designed so robust that a reliable operation is guaranteed.
- the slide contours which are in operative connection with one another, are mounted on the outside of the housing, so that the interior of the pushbutton, which is already very limited anyway, can be used elsewhere.
- Another decisive advantage is that the sliding contours are structurally kept so simple that they are preferably arranged in a plurality on the housing or on the actuating head, so that even if a sliding contour damage the other sliding contours can still work properly and the pushbutton therefore not a total must be replaced.
- Fig. 1 shows a pushbutton 1 according to the invention with an actuating head 2, which is formed from a cap 3 and a cover member 4, and a housing 5 which is formed as a rosette with a cylindrical base body.
- the cap 3 is preferably concentric and has a A plurality of preferably regularly arranged recesses 6, which allow a view of the underlying cover element 4.
- Below the cap 3, the lid member 4 is arranged, which is also formed concentrically and the color different display surfaces 7 provides for the switching state detection.
- the lid member 4 opens laterally into beveled cylinder shell part section surfaces 8, which serve as a sliding contour and form the first part of a sliding pair.

Abstract
Description
Die Erfindung betrifft einen Drucktaster mit einer mechanischen Signalanzeige für die Schaltung einer Schalteinheit, aufweisend einen Betätigungskopf und ein Gehäuse, wobei die mechanische Anzeige im Betätigungskopf angeordnet ist und mindestens eine Ausnehmung aufweist sowie eine durch die Ausnehmung erkennbare Anzeigefläche.The invention relates to a push button with a mechanical signal display for the circuit of a switching unit, comprising an actuating head and a housing, wherein the mechanical display is arranged in the actuating head and has at least one recess and a recognizable by the recess display area.
Elektromechanische Befehlsgeräte werden zur Bedienung und Steuerung von Maschinen und Anlagen weitläufig verwendet. Sie treten in verschiedenen Ausprägungen, zum Beispiel als Drucktaster, Knebelschalter, Schlüsselschalter oder Not-AusSchalter auf. Befehlsgeräte werden auf Schalttafeln, Bedientableaus, Schaltschranktüren oder Gehäusedecken montiert. Durch manuelles Betätigen der Befehlsgeräte werden elektrische Schaltzustandsänderungen und damit die gewünschten Steuerungseffekte erzeugt. Befehlsgeräte werden standardmäßig mit einer mechanischen Anzeige ausgerüstet, um herrschende Schaltzustände anzuzeigen, wobei die mechanische Anzeige gegebenenfalls alternativ oder zusätzlich mit einer leuchtbaren oder beleuchteten Einheit bestückt ist.Electromechanical command devices are widely used to operate and control machinery and equipment. They occur in various forms, for example as pushbuttons, toggle switches, key switches or emergency stop switches. Command devices are mounted on control panels, control panels, control cabinet doors or enclosure covers. By manually operating the command devices electrical switching state changes and thus the desired control effects are generated. Command devices are equipped as standard with a mechanical display to indicate prevailing switching states, the mechanical display optionally optionally or additionally equipped with a luminous or illuminated unit.
Befehlsgeräte sind in der Regel modular aufgebaut. Das bedeutet, sie bestehen aus einem Druckknauf, einem Befestigungsteil, wie zum Beispiel einer Ringmutter oder einem Montagehalter und einem oder mehreren Schaltelementen, die als Öffner- oder Schließerschaltglieder ausgeführt sind. Zur Montage wird der Betätiger in der Regel von vorn durch ein Loch in der Schalttafel geführt und von hinten mittels eines Befestigungsteils montiert. Die Schaltelemente werden mit Schrauben, Schnapphaken oder Riegeln mechanisch am Betätiger oder am Befestigungsteil befestigt. Die elektrische Verbindung der Schaltelemente mit der Steuerung erfolgt über Anschlussklemmen. Bei Sicherheitsanwendungen wie zum Beispiel Not-Aus-Befehlsgeräten ist es Vorschrift, dass das Signal durch das Öffnen von zwangsöffnenden Kontakten erzeugt wird. Das heißt, dass bei einem unbetätigten Not-Aus-Befehlsgerät die Kontakte und damit der zugehörige Stromkreis geschlossen sind. Im Störungs- oder Notfall wird durch Schlagen auf den Not-Aus-Betätiger, der sich vor der Schalttafel befindet, der Öffnerkontakt unterbrochen und die Anlage oder Maschine in einen sicheren Zustand versetzt. Dies funktioniert jedoch nur, wenn die räumliche Zuordnung zwischen Betätiger und Schaltelement sichergestellt ist. Durch mangelhafte Montage oder durch Gewalteinwirkung kann es vorkommen, dass die Schaltelemente mechanisch vom Betätiger getrennt werden. In diesem Fall ist das Not-Aus-Befehlsgerät nicht mehr funktionsfähig. Das heißt, bei einer Betätigung im Notfall werden die Kontakte nicht geöffnet und damit erfolgt auch keine Beseitigung des Gefahrenzustands. Dies kann zu fatalen Schäden für Mensch und Maschine führen. Daher kommt der sicheren Verbindung zwischen Betätiger und Schaltelement eine wesentliche Bedeutung zu.Command devices are generally modular. That is, they consist of a push button, a fastening part, such as a ring nut or a mounting bracket and one or more switching elements, which are designed as normally closed or normally closed contacts. For installation, the actuator is usually guided from the front through a hole in the dash panel and mounted from behind by means of a fastening part. The switching elements are mechanically fastened with screws, snap hooks or bolts on the actuator or on the fastening part. The electrical connection of the switching elements to the controller via terminals. For safety applications such as emergency stop command devices, it is mandatory that the signal be sent through the Opening of positively-opening contacts is generated. This means that with an unconfirmed emergency stop command device, the contacts and thus the associated circuit are closed. In the event of a fault or emergency, the normally closed contact is interrupted by striking the emergency stop actuator, which is located in front of the control panel, and the system or machine is put into a safe state. However, this only works if the spatial assignment between the actuator and the switching element is ensured. Due to poor installation or due to the effects of force, it may happen that the switching elements are mechanically separated from the actuator. In this case, the emergency stop command device is no longer functional. That is, in an emergency operation, the contacts are not opened and thus there is no elimination of the dangerous condition. This can lead to fatal damage to man and machine. Therefore, the secure connection between actuator and switching element is essential.
Die Forderung nach einer integrierten optischen Anzeige, bei der es sich sowohl um eine mechanische und/oder elektrische Schaltanzeige handelt, führt zu einem Problem hinsichtlich der Unterbringung der erforderlichen Bauteile, da das Gesamtvolumen des Gerätes, insbesondere durch einen genormten Einbaudurchmesser (zum Beispiel 22,5 mm), nur in engen Grenzen variiert werden kann. Bisher wurde, wenn eine Integration der Anzeige in das Befehlsgerät nicht möglich war, meist eine zusätzliche Befehlsstelle, beispielsweise mit einem Leuchtmelder angebracht. Auf Grund des zusätzlichen Platzbedarfs, zum Beispiel auf einer Schalttafel der Installationseinheit und der zwingenden Verwendung einer separaten Anzeige, ist diese Lösung unvorteilhaft.The requirement for an integrated optical display, which is both a mechanical and / or electrical switching display, leads to a problem with regard to the accommodation of the required components, since the total volume of the device, in particular by a standard mounting diameter (for example 22, 5 mm), can only be varied within narrow limits. So far, if an integration of the display in the command device was not possible, usually an additional command point, for example, attached with a light. Due to the extra space required, for example on a panel of the installation unit and the mandatory use of a separate display, this solution is unfavorable.
Aus dem Stand der Technik geht dazu aus der der
Der Nachteil am Stand der Technik besteht darin, dass die mechanische Anzeigefläche über sehr feingliedrige mechanische Bauelemente geführt ist, die auf Grund der räumlichen Enge im Befehlsgerät leicht verkanten oder sich verformen können und als Konsequenz eine vorschriftsmäßige Bedienung des Befehlsgerätes nicht mehr zulassen.The disadvantage of the prior art is that the mechanical display surface is guided over very delicate mechanical components that can easily tilt or deform due to the spatial tightness in the command device and as a consequence no longer allow a proper operation of the command device.
Demgemäß besteht die Aufgabe der vorliegenden Erfindung darin, einen Drucktaster mit einer mechanischen Signalanzeige zu schaffen, der konstruktiv einfach gehalten ist und eine zuverlässige Bedienung ermöglicht.Accordingly, the object of the present invention is to provide a push button with a mechanical signal display, which is structurally simple and allows reliable operation.
Diese Aufgabe wird durch einen Drucktaster mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Aus- und Weiterbildungen, welche einzeln oder in Kombination miteinander eingesetzt werden können, sind der Gegenstand der abhängigen Ansprüche.This object is achieved by a push-button with the features of claim 1. Advantageous embodiments and developments, which can be used individually or in combination with each other, are the subject of the dependent claims.
Erfindungsgemäß wird diese Aufgabe durch einen Drucktaster mit einer mechanischen Signalanzeige für die Schaltung einer Schalteinheit gelöst, aufweisend einen Betätigungskopf und ein Gehäuse, wobei die mechanische Anzeige im Betätigungskopf angeordnet ist und mindestens eine Ausnehmung aufweist sowie eine durch die Ausnehmung erkennbare Anzeigefläche. Die Erfindung zeichnet sich dadurch aus, dass am Betätigungskopf und am Gehäuse Gleitkonturen angeordnet sind, die miteinander in Wirkverbindung stehen. Der erfindungsgemäße Drucktaster ist konstruktiv einfach ausgestaltet, dabei aber trotzdem so robust ausgeführt, dass eine zuverlässige Bedienung gewährleistet ist. Die miteinander in Wirkverbindung stehenden Gleitkonturen sind gehäuseaußenseitig angebracht, so dass der sowieso schon sehr begrenzte Innenraum des Drucktasters anderweitig genutzt werden kann. Die außenseitige Anbringung der Gleitkonturen, die zum Einen an der Außenseite des Gehäuses angeordnet sind, sowie zum Anderen am Betätigungskopf in einem Teilbereich, der über dem Gehäuse geführt ist, weist den weiteren Vorteil auf, dass selbst bei Beschädigung der Gleitkonturen die abgesprungen Teil nicht in den Innenraum des Drucktasters fallen und dort eine Betätigung des Drucktasters verhindern. Ein weiterer entscheidender Vorteil besteht darin, dass die Gleitkonturen konstruktiv so einfach gehalten sind, dass sie vorzugsweise in einer Mehrzahl am Gehäuse beziehungsweise am Betätigungskopf angeordnet sind, so dass selbst bei Beschädigung einer Gleitkontur die anderen Gleitkonturen noch vorschriftsmäßig funktionieren können und der Drucktaster deswegen nicht insgesamt ausgetauscht werden muss.This object is achieved by a push button with a mechanical signal display for the circuit of a switching unit, comprising an actuating head and a housing, wherein the mechanical display is arranged in the actuating head and has at least one recess and a recognizable by the recess display area. The invention is characterized in that sliding contours are arranged on the actuating head and on the housing, which are in operative connection with one another. The pushbutton according to the invention is designed structurally simple, but still so robust designed that ensures reliable operation is. The slide contours, which are in operative connection with one another, are mounted on the outside of the housing, so that the interior of the pushbutton, which is already very limited anyway, can be used elsewhere. The outside attachment of the sliding contours, which are arranged on the one hand on the outside of the housing, and on the other on the actuating head in a partial area which is guided over the housing, has the further advantage that even if the sliding contours are damaged, the detached part does not engage in fall inside the push button and prevent actuation of the pushbutton there. Another decisive advantage is that the sliding contours are structurally kept so simple that they are preferably arranged in a plurality on the housing or on the actuating head, so that even if a sliding contour damage the other sliding contours can still work properly and the pushbutton therefore not a total must be replaced.
In einer besonders vorteilhaften Ausführungsform ist vorgesehen, dass das Gehäuse als Rosette, also als zylindrische Grundform ausgebildet ist. Dieser Grundkörper hat sich insbesondere für die Betätigung des Betätigungskopfes vorteilhaft erwiesen, da die zylindrische Form keine Kanten bietet, an denen der Betätigungskopf im Betätigungsfall verhaken könnte.In a particularly advantageous embodiment it is provided that the housing is designed as a rosette, so as a cylindrical basic shape. This body has proven to be particularly advantageous for the actuation of the actuating head, since the cylindrical shape offers no edges at which the actuating head could get caught in the actuation case.
Es ist insbesondere von Vorteil, wenn die Gleitkontur am Gehäuse als Gleitsteg ausgebildet ist. Dieser erfindungsgemäße Gleitsteg wirkt als Führungssteg und steht mit der abgeschrägten Zylindermantelteilabschnittsfläche des Betätigungskopfes in Wirkverbindung. Nach Betätigung des Betätigungskopfes ist die abgeschrägte Zylindermantelteilabschnittsfläche dann zwischen zwei Führungsstegen angeordnet.It is particularly advantageous if the sliding contour is formed on the housing as a sliding web. This sliding web according to the invention acts as a guide web and is in operative connection with the bevelled cylinder jacket part section surface of the actuating head. After actuation of the actuating head, the slanted Zylindermantelteilabschnittsfläche is then arranged between two guide webs.
In einer besonders vorteilhaften Ausführungsform ist vorgesehen, dass die Gleitstege in vorzugsweise regelmäßigen Abständen um das Gehäuse angeordnet sind. Damit ergeben sich mehrere Gleitkonturpaare aus Gleitstegen und abgeschrägten Zylindermantelteilabschnittsflächen, die es erlauben, den Drucktaster auch weiter zu verwenden, wenn eines dieser Gleitpaare beschädigt wird.In a particularly advantageous embodiment, it is provided that the sliding webs are arranged at preferably regular intervals around the housing. This results in several Sliding contour pairs of sliding webs and bevelled cylindrical shell section areas, which allow the pushbutton to continue to be used if one of these sliding pairs is damaged.
Vorteilhafterweise ist vorgesehen, dass die Gleitkontur am Betätigungskopf als abgeschrägte Zylindermantelteilabschnittsfläche ausgebildet ist. Dabei ist im Betätigungsfall vorgesehen, dass die abgeschrägte Zylindermantelteilabschnittsfläche an einer Kante eines Führungssteges heruntergleitet, bis der Betätigungskopf in der Endposition angelangt ist.Advantageously, it is provided that the sliding contour is formed on the actuating head as a chamfered cylinder jacket part section surface. It is provided in the case of actuation that the slanted Zylindermantelteilabschnittsfläche slides down on an edge of a guide bar until the actuating head has arrived in the end position.
In einer besonders vorteilhaften Ausführungsform ist vorgesehen, dass die mechanische Signalanzeige für die Zustandsanzeige von mindestens zwei Schaltzuständen ausgebildet ist. Diese zwei unterschiedlichen Schaltzustände können durch unterschiedliche Farben, wie zum Beispiel grün und rot, angezeigt werden, die in einem Deckelelement des Betätigungskopfes, das in die abgeschrägte Zylindermantelteilabschnittsfläche mündet, aufgetragen sind.In a particularly advantageous embodiment, it is provided that the mechanical signal display for the status display of at least two switching states is formed. These two different switching states may be indicated by different colors, such as green and red, applied in a lid member of the actuator head which terminates in the beveled cylindrical shell portion portion.
Es ist vorteilhaft, wenn die Gleitkonturen aus Kunststoff ausgebildet sind. Dieses Material ermöglicht einen leichten Gleitvorgang zwischen den abgeschrägten Zylindermantelteilabschnittsflächen und den Gleitstegen. Zudem ist Kunststoff formstabil und unterliegt keinen größeren Alterungsprozessen.It is advantageous if the sliding contours are formed from plastic. This material allows for a smooth sliding action between the beveled cylinder shell portion surfaces and the sliding webs. In addition, plastic is dimensionally stable and is not subject to major aging processes.
In einer besonders vorteilhaften Ausführungsform ist vorgesehen, dass die Gleitkonturen außenseitig am Gehäuse und am Betätigungskopf angeordnet sind. Die außenseitige Anbringung der Gleitstrukturen führt dazu, dass der Innenraum des Drucktasters anderweitig verwendet werden kann. Außerdem fallen abspritzende Kunststoffteile nicht in den Innenraum des Drucktasters, wo sie einer Betätigung des Drucktasters entgegenstehen könnten.In a particularly advantageous embodiment, it is provided that the sliding contours are arranged on the outside of the housing and on the actuating head. The external attachment of the sliding structures results in that the interior of the pushbutton can be used elsewhere. In addition, sprayed plastic parts do not fall into the interior of the pushbutton, where they could oppose an actuation of the pushbutton.
Der erfindungsgemäße Drucktaster ist konstruktiv einfach ausgestaltet, dabei aber trotzdem so robust ausgeführt, dass eine zuverlässige Bedienung gewährleistet ist. Die miteinander in Wirkverbindung stehenden Gleitkonturen sind gehäuseaußenseitig angebracht, so dass der sowieso schon sehr begrenzte Innenraum des Drucktasters anderweitig genutzt werden kann. Ein weiterer entscheidender Vorteil besteht darin, dass die Gleitkonturen konstruktiv so einfach gehalten sind, dass sie vorzugsweise in einer Mehrzahl am Gehäuse beziehungsweise am Betätigungskopf angeordnet sind, so dass selbst bei Beschädigung einer Gleitkontur die anderen Gleitkonturen noch vorschriftsmäßig funktionieren können und der Drucktaster deswegen nicht insgesamt ausgetauscht werden muss.The pushbutton according to the invention is structurally simple in design, but still designed so robust that a reliable operation is guaranteed. The slide contours, which are in operative connection with one another, are mounted on the outside of the housing, so that the interior of the pushbutton, which is already very limited anyway, can be used elsewhere. Another decisive advantage is that the sliding contours are structurally kept so simple that they are preferably arranged in a plurality on the housing or on the actuating head, so that even if a sliding contour damage the other sliding contours can still work properly and the pushbutton therefore not a total must be replaced.
