The invention relates to an emergency shutdown device according to the preamble of Claim 1 and an emergency shutdown device according to the preamble of the claim Second

Stand der TechnikState of the art

Sowohl aus der Druckschrift DE 93 06 074 U1 als auch aus der Druckschrift DE 35 46 059 C2 ist eine Notabschalteinrichtung mit einem rohrförmigen stationären Führungsteil, einem an diesem mittels einer Kulisse verschieblich gelagerten Betätigungsknopf, einem Kontaktelemente betätigenden Betätigungsstößel, der über einen Mitnehmer axial verschieblich mit der Kulisse verbunden ist, und einer Betätigungsknopf und Betätigungsstößel beaufschlagenden Spannfeder bekannt. Beim Niederdrücken des Betätigungsknopfes aus der ungedrückten Ausgangsstellung wird die Spannfeder gegen den Widerstand elastischer Sprungelemente soweit zusammengedrückt, bis nach Überwindung des Widerstandes der Sprungelemente die bis dahin aufgebaute Energie der Spannfeder zu einer zwangsläufigen Fortbewegung des Betätigungsstößels und damit überlistungssicheren Abschaltung der Kontaktelemente führt. Zur Überführung des Betätigungsknopfes durch Ziehen in seine Ausgangsstellung ist über den Mitnehmer der Widerstand der Sprungelemente in umgekehrte Richtung zu überwinden, worauf der Betätigungsknopf nach DE 93 06 074 U1 durch die Wirkung der Spannfeder und nach DE 35 46 059 C2 durch die Wirkung einer Betätigungsknopf und Führungsteil beaufschlagenden Rückholfeder jeweils in seine Ausgangsstellung gelangt. Both from the publication DE 93 06 074 U1 and from the publication DE 35 46 059 C2 is an emergency shutdown device with a tubular stationary one Guide part, one on this by means of a backdrop stored actuation button, an actuating plunger actuating contact elements, the axially displaceable with the backdrop via a driver is connected, and an actuating button and actuating plunger act Tension spring known. When pressing the actuation button from the unpressed starting position the tension spring against the Resistance of elastic jump elements pressed together until after Overcoming the resistance of the jump elements the previously built Energy of the tension spring for an inevitable movement of the actuating plunger and thus foolproof switching off of the contact elements leads. To transfer the operating button by pulling it into its The starting position is the resistance of the jump elements via the driver to overcome in the opposite direction, whereupon the push button according to DE 93 06 074 U1 due to the action of the tension spring and according to DE 35 46 059 C2 acted upon by the action of an operating button and guide member Return spring in its original position.

Von Nachteil bei diesen bekannten Notabschalteinrichtungen sind die durch Reibung zwischen den untereinander bewegten Teilen ungenügend genau bestimmbaren Auslösekräfte und Auslösewege beim Niederdrücken des Betätigungsknopfes sowie die mit der Reibung verbundenen Verschleißerscheinungen.The disadvantage of these known emergency shutdown devices is that of Friction between the moving parts is insufficiently accurate determinable release forces and release paths when pressing the actuation button and the signs of wear associated with the friction.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt daher die Aufgabe zugrunde, die Reproduzierbarkeit des Auslöseverhaltens von Notabschalteinrichtungen zu erhöhen.The invention is therefore based on the object, the reproducibility of the Increase trigger behavior of emergency shutdown devices.

Ausgehend von Notabschalteinrichtungen der eingangs genannten Art wird die Aufgabe erfindungsgemäß durch die kennzeichnenden Merkmale der unabhängigen Ansprüche gelöst, während den Unteransprüchen vorteilhafte Weiterbildungen zu entnehmen sind.Starting from emergency shutdown devices of the type mentioned the task according to the invention by the characterizing features of the independent Claims solved, while the subclaims advantageous Further training can be found.

Der Betätigungsknopf wird durch die Spannfeder bzw. die Rückholfeder und die Sperrkörper daran gehindert, im unbetätigten Zustand aus seiner Ruheposition zu gelangen. Beim Betätigen des Betätigungsknopfes wird die Kulisse entgegen der Spannkraft der Spannfeder soweit verlagert, bis die im Führungsteil gelagerten Sperrkörper aus dem Eingriff der sperrenden Schrägen der Sperrflächen an der Kulisse freigegeben werden, wodurch der Betätigungsstößel durch die freiwerdende Energie der Spannfeder zwangsläufig gegen das Kontaktelement bewegt wird. Durch die erfindungsgemäßen Mittel wird erreicht, daß bei jeder Betätigung sowohl ein gleichbleibender, durch die Sperrflächen und die Lage der Ausnehmungen für die Sperrkörper definierte Auslöseweg als auch eine gleichbleibende, durch den Auslöseweg und die Spannfeder definierte Auslösekraft auftritt. Beim Zurücksetzen wird über den Betätigungsknopf und den Mitnehmer der Betätigungsstößel soweit zurückgezogen, bis die Sperrkörper über den Eingriff der Schrägen an der Kulisse wieder in den Eingriff der Schrägen am Betätigungsstößel gelangen. Die den Betätigungsstößel verriegelnde Kulisse wird in dem einem Falle durch die Spannfeder und dem anderen Falle durch die Rückholfeder in ihre Ausgangslage zurückgebracht. Die Spannfeder wird in dem einem Fall beim Betätigen und in dem anderen Fall beim Zurücksetzen des Betätigungsknopfes gespannt. Die Abstufung der Sperrflächen erfolgt jeweils mit einer Schräge, die in der Weise verläuft, daß die Sperrkörper im Verlauf der Betätigung bzw. der Rücksetzung des Betätigungsknopfes eine Bewegungskomponente senkrecht zur Betätigungsrichtung des Betätigungsknopfes ausführen.The actuation button is by the tension spring or the return spring and the blocking body prevented from being in its unactuated state from its rest position to get. When you press the control button, the backdrop against the tensioning force of the tension spring until it moves in the guide part stored locking body from the engagement of the locking bevels the locking surfaces on the backdrop are released, causing the actuating plunger due to the energy released by the tension spring is moved against the contact element. By means of the invention is achieved that with each actuation both a constant, by the Blocked areas and the position of the recesses for the blocking body defined Trigger path as well as a constant, through the trigger path and the Tension spring defined trigger force occurs. When resetting, the Actuation button and the driver of the actuating plunger withdrawn as far as until the locking body over the engagement of the bevels on the backdrop again get into the engagement of the bevels on the actuating plunger. The the actuating plunger interlocking backdrop is in one case by the Tension spring and the other case by the return spring in their starting position brought back. In this case, the tension spring is activated and in the other case cocked when resetting the operating button. The graded areas are graded with a slope, the runs in such a way that the locking body in the course of the operation or Resetting the control button a movement component vertically to the actuation direction of the actuation button.

Die Sperrflächen können konzentrisch bzw. eben parallel, umlaufend senkrecht oder schief oder radial zur Mittelachse der Notabschalteinrichtung angeordnet sein. Die Richtung der Abstufung der Sperrflächen kann radial, senkrecht tangential, schief tangential oder parallel zur Mittelachse verlaufen. Daraus läßt sich erkennen, daß durch entsprechende Anordnung der Sperrflächen und ihrer Schrägen die Verlagerung der Sperrkörper in den Ausnehmungen des Führungsteils zur Auslösung bzw. Verriegelung des Betätigungsstößels radial, tangential umlaufend oder parallel zur Mittelachse der Notabschalteinrichtung erfolgt oder aus einer Zusammensetzung der vorgenannten Verlagerungsbewegungen besteht. Mit diesen Möglichkeiten läßt sich die Erfindung mit Vorteil auf Notabschalteinrichtungen übertragen, die zum einen translatorisch, rotatorisch oder translatorisch-rotatorisch betätigt werden und bei denen zum anderen der Betätigungsstößel innerhalb oder außerhalb der Kulisse angeordnet ist. Als Sperrkörper lassen sich mit Vorteil kugelige oder zylindrische starre Körper, die im letzten Fall mit in einer Richtung geradlinig verlaufenden Sperrflächen zusammenwirken, verwenden. Ebenso können die Sperrkörper einstückig mit dem Führungsteil bewegbar verbunden sein.The blocking areas can be concentric or even parallel, circumferentially perpendicular or arranged obliquely or radially to the central axis of the emergency shutdown device his. The direction of the gradation of the blocking surfaces can be radial, vertical tangential, oblique tangential or parallel to the central axis. From this it can be seen that by appropriate arrangement of the blocking areas and their bevels the displacement of the locking body in the recesses of the guide part for triggering or locking the actuating plunger radial, tangential or parallel to the central axis of the emergency shutdown device takes place or from a composition of the aforementioned Relocation movements exist. With these possibilities, the invention can be transferred advantageously to emergency shutdown devices, on the one hand are operated in a translatory, rotary or translatory-rotary manner and on the other hand, the actuating plunger inside or outside the Backdrop is arranged. As a blocking body can advantageously be spherical or cylindrical rigid body, which in the latter case is rectilinear in one direction interacting blocking areas, use. Likewise, the Locking body can be connected integrally with the guide part.

Bester Weg zur Ausführung der ErfindungBest way to carry out the invention

Die Notabschalteinrichtung 1 nach Fig. 1 ist mit einem rohrförmigen stationären Führungsteil 4 und einem Betätigungsknopf 6 versehen. An dem Führungsteil 4 ist der Betätigungsknopf 6 mittels einer an ihm befestigten Kulisse 8 verschieblich gelagert. In der Kulisse 8 ist ein Betätigungsstößel 10 für nicht dargestellte Kontaktelemente angeordnet. Der Betätigungsstößel 10 ist über einen mit dem Betätigungsknopf 6 verbundenen Mitnehmer 12 in bzw. entgegen der Betätigungsrichtung D verschieblich mit der Kulisse 8 gekoppelt. Eine druckbeaufschlagte Spannfeder 14 stützt sich an entsprechenden Flächenelementen zwischen Betätigungsknopf 6 und Betätigungsstößel 10 ab. Die Kulisse 8 und der Betätigungsstößel 10 sind gegenüberliegend mit Sperrflächen 16 bzw. 18 ausgestattet. Die zur Mittelachse 20 weisende Sperrflächen 16 der Kulisse 8 sind jeweils aus ersten Teilflächen 22, gegenüber diesen nach außen zurückgesetzten zweiten Teilflächen 26 sowie die Teilflächen 22 und 26 verbindenden Schrägen 30 zusammengesetzt. Die von der Mittelachse 20 weisenden Sperrflächen 18 des Betätigungsstößels 10 sind jeweils aus ersten Teilflächen 24, gegenüber diesen nach außen zurückgesetzten zweiten Teilflächen 28 sowie die beiden Teilflächen 24 und 28 verbindenden Schrägen 32 zusammengesetzt. Die Sperrflächen 16 und 18 sind demnach senkrecht zur Betätigungsrichtung D und von der Mittelachse 20 nach außen abgesetzt. In Ausnehmungen 34 des Führungsteiles 4 sind kugelförmige steife Sperrkörper 36 gelagert, die an beiden Sperrflächen 16 und 18 anliegen.The emergency shutdown device 1 according to FIG. 1 has a tubular stationary one Guide part 4 and an actuating button 6 provided. On the guide part 4 is the actuating button 6 by means of a backdrop attached to it 8 slidably mounted. In the backdrop 8 is an actuating plunger 10 for shown contact elements arranged. The actuating plunger 10 is over a driver 12 connected to the actuating button 6 in or against the actuation direction D slidably coupled to the backdrop 8. A pressurized tension spring 14 is supported on corresponding surface elements between actuating button 6 and actuating plunger 10. The Setting 8 and the actuating plunger 10 are opposite with locking surfaces 16 or 18 equipped. The blocking surfaces facing the central axis 20 16 of the backdrop 8 are each made of first partial areas 22, opposite these outwardly recessed second partial surfaces 26 and the partial surfaces 22 and 26 connecting bevels 30 composed. That of the central axis 20 facing locking surfaces 18 of the actuating plunger 10 are each made first sub-areas 24, in relation to this second set back Sub-areas 28 and the two sub-areas 24 and 28 connecting bevels 32 composed. The blocking surfaces 16 and 18 are therefore vertical to the actuation direction D and offset from the central axis 20 to the outside. In recesses 34 of the guide part 4 are spherical rigid locking bodies 36 mounted, which rest on both locking surfaces 16 and 18.

Beim Niederdrücken des Betätigungsknopfes 6 der Notabschalteinrichtung 1 aus der dargestellten Ausgangslage in Betätigungsrichtung D wird die Kulisse 8 in die gleiche Richtung verschoben. Solange die Sperrkörper 36 an den ersten Teilflächen 22 der zur Kulisse 8 gehörenden Sperrflächen 16 anliegen, ist der Betätigungsstößel 10 daran gehindert, mit seinen Schräge 32 an den Sperrkörpern 36 vorbei zu gleiten. Während dieser Bewegungsphase wird die bereits vorgespannte Spannfeder 14 zunehmend zusammengedrückt. Im Verlauf der weiteren Betätigung in Betätigungsrichtung D gelangen die Sperrkörper außer Eingriff von den ersten Teilflächen 22 der Kulisse 8, aber dafür in Eingriff mit den Schrägen 30 der Kulisse 8. In weiteren Verlauf dieser Bewegungsphase verlagern sich die Sperrkörper 36 durch die Kraftwirkung der Spannfeder 14 über die Schrägen 32 des Betätigungsstößels 10 nach außen und gelangen schließlich außer Eingriff von den Schrägen 32. Der ausgelöste Betätigungsstößel 10 wird daraufhin zwangsläufig durch die sich entladende Federenergie der Spannfeder 14 weiter in Betätigungsrichtung D getrieben. Beim Zurücksetzen des Betätigungsknopfes 6 entgegen der Betätigungsrichtung D wird der Betätigungsstößel 10 über den Mitnehmer 12 zurückgeführt, wobei die Sperrkörper 36 durch die Schrägen 30 der Kulisse 8 wieder zur Anlage gegen die Schrägen 32 des Betätigungsstößels 10 verlagert werden. Der Betätigungsknopf 6 wird schließlich durch die Federkraft der Spannfeder 14 in seiner wieder erreichten Ausgangsposition gehalten.When the actuation button 6 of the emergency shutdown device 1 is depressed from the starting position shown in the direction of actuation D becomes the backdrop 8 moved in the same direction. As long as the locking body 36 on the first Partial areas 22 of the blocking areas 16 belonging to the backdrop 8 are present the actuating plunger 10 prevented with its bevel 32 to the Sliding bodies 36 slide past. During this movement phase the already preloaded tension spring 14 increasingly compressed. in the The locking bodies pass in the course of further actuation in actuation direction D. disengaged from the first sub-areas 22 of the backdrop 8, but in Engagement with the slopes 30 of the backdrop 8. In the further course of this movement phase shift the locking body 36 by the force of the Tension spring 14 on the slopes 32 of the actuating plunger 10 to the outside and finally disengage from the slopes 32. The triggered one Actuating plunger 10 is then inevitably caused by the discharging Spring energy of the tension spring 14 further driven in the actuation direction D. When resetting the operating button 6 against the operating direction D the actuating plunger 10 is returned via the driver 12, the locking body 36 through the bevels 30 of the backdrop 8 back to the system be displaced against the slopes 32 of the actuating plunger 10. The Actuating button 6 is finally in by the spring force of the tension spring 14 maintained its starting position.

Die Notabschalteinrichtung 2 nach Fig. 2 unterscheidet sich von der vorstehend beschriebenen dadurch, daß sich an entsprechenden Flächenelementen die auf Druck vorgespannte Spannfeder 14 zwischen Führungsteil 4 und Betätigungsstößel 10 und eine druckbeaufschlagte Rückholfeder 38 zwischen Betätigungsknopf 6 und Führungsteil 4 abstützt.The emergency shutdown device 2 according to FIG. 2 differs from that above described in that appropriate surface elements the prestressed tension spring 14 between the guide member 4 and the actuating plunger 10 and a pressurized return spring 38 between Actuating button 6 and guide part 4 supports.

Beim Niederdrücken und Zurücksetzen des Betätigungsknopfes 6 der Notabschalteinrichtung 2 in bzw. entgegen der Betätigungsrichtung D wirken die Sperrkörper 36 mit den Sperrflächen 16 und 18 von Kulisse 8 bzw. Betätigungsstößel 10 in der gleichen, vorstehend für die Notabschalteinrichtung 1 nach Fig. 1 beschriebenen Weise zusammen. Beim Niederdrücken des Betätigungsknopfes 6 aus der dargestellten Ausgangslage in Betätigungsrichtung D wird die Kulisse 8 in gleiche Richtung verschoben, bis durch Freigabe der Sperrkörper 36 die sich entspannende Spannfeder 14 den ausgelösten Betätigungsstößel 10 zwangsläufig in Richtung der Kontaktelemente treibt. Beim Niederdrücken wird die Rückholfeder 38 vollkommen zusammengedrückt. Beim Zurücksetzen des Betätigungsknopfes 6 entgegen der Betätigungsrichtung D wird der Betätigungsstößel 10 über den Mitnehmer 12 zurückgeführt wobei die Spannfeder 14 vorgespannt wird. Sobald der Betätigungsstößel 10 die Sperrkörper 36 freigibt, wird die Kulisse 8 durch die Federkraft der Rückholfeder 38 in seine Ausgangsposition zurückbewegt und dort gehalten.When depressing and resetting the operating button 6 of the emergency shutdown device 2 act in or against the direction of actuation D. Locking body 36 with the locking surfaces 16 and 18 of link 8 or actuating plunger 10 in the same, above for the emergency shutdown 1 1 described together. When pressing the actuation button 6 from the starting position shown in the actuating direction D the backdrop 8 is moved in the same direction until the release Locking body 36, the relaxing tension spring 14, the actuated tappet 10 inevitably drives in the direction of the contact elements. At the The return spring 38 is completely pressed down. When resetting the operating button 6 against the operating direction D, the actuating plunger 10 is returned via the driver 12 wherein the tension spring 14 is biased. As soon as the actuating plunger 10 releases the locking body 36, the backdrop 8 by the spring force of the return spring 38 moved back to its starting position and held there.

So läßt sich die Erfindung beispielsweise auch mit zylindrischen Sperrkörpern 36 ausführen, wobei sich in diesem Falle die Sperrflächen 16 und 18 aus jeweils ebenen ersten Teilflächen 22 bzw. 24, zweiten Teilflächen 26 bzw. 28 und Schrägen 30 bzw. 32 zusammensetzen.For example, the invention can also be used with cylindrical locking bodies 36 perform, in which case the blocking surfaces 16 and 18 each flat first partial surfaces 22 and 24, second partial surfaces 26 and 28 and assemble slopes 30 and 32 respectively.
