Definitions
- the invention relates to a switch arrangement with an actuating member, the lateral displacement of which at least one of a plurality of switches can be actuated and which acts on a further switch when pressed against the force of a spring via a switching plunger.
- Such switch arrangements can be used, for example, to control the drive motors for a table top in an X-ray examination apparatus, the direction of actuation and the direction in which the table top is displaced by actuating the switch arrangement expediently coinciding.
- actuating the further switch By actuating the further switch, a further function that is independent of the table top displacement can then be switched.
- a known switch device of the type mentioned four microswitches are arranged around the plunger, in such a way that their sides provided with a switching element face the cylindrical plunger which presses against one of the switching elements when the actuating member is laterally displaced.
- the overall volume of such a switch arrangement can be reduced by arranging the microswitches as close as possible to the switching plunger. Then, however, a small displacement of the actuating member is sufficient to trigger a switching operation.
- Such short switching distances are disadvantageous for the user; in an X-ray examination device, for example, in which the user in generally wearing lead rubber gloves and acting with the thumb on the actuator, the user loses the feeling of whether the switch is actuated or not with such short switching distances.
- Another disadvantage is that the forces that the user exerts on the actuator must be fully absorbed by the switches.
- the object of the present invention is to design a switch arrangement of the type mentioned at the outset in such a way that, despite the small construction volume, there are sufficiently long switching paths.
- This object is achieved in that the sides provided with a switching element of the switches which can be actuated by lateral displacement lie in one plane, in that the switching elements are arranged around a switching plate which is displaceable in the plane, and in that the switching plate is arranged displaceably on the switching plunger.
- the switching plunger is formed in two parts, one of the plunger parts interacting with the switching plate being rigidly connected to the actuating member and the other plunger part acting on the further switch being displaceable perpendicular to the plane, and that two pusher parts offset in the axial direction are pressed against one another by a tension spring with the surfaces facing one another.
- the switching elements are actuated in that the switch plate runs over them.
- the forces exerted by the user on the actuator are not transmitted to the individual switches.
- the actuating member is displaced perpendicular to the plane, the first plunger partially acts on the second, which is guided in this direction and actuates the switching element of the further switch.
- the actuating member is laterally displaced, the first tappet part tilts relative to the second, the latter not moving, but the indexing plate is displaced until it actuates at least one switching element.
- the actuator is reset using the tension spring under tension.
- this tension spring With a suitable design of this tension spring, the tension exerted by it is only slightly increased when the actuating member is laterally displaced, so that the (restoring) force counteracting the actuating force of the user remains essentially constant during the displacement. The ease of use is significantly increased.
- the switch arrangement shown in the drawing - a so-called coordinate switch - has an assembly and guide body 1 on which five microswitches are attached. Four of them, namely the microswitches 2, 3, 4 and 5 are arranged so that their switching elements 2a, 3a, 4a and 5a lie on the corner points of a square and their sides provided with the switching elements form a plane which is parallel in FIG. 2 to the drawing plane and in Fig. 1 perpendicular to the drawing plane, the horizontal in Fig. 1 running intersection line with the drawing plane is designated 6.
- the button-shaped actuator 7 and the switching plunger is in the center of these four switches.
- the switching plunger running vertically in FIG. 1 and perpendicular to the plane of the drawing in FIG. 2 consists of two rotationally symmetrical parts 8 and 9, which are arranged one behind the other in the axial direction.
- the tappet part 8 connected to the actuating member 7 has a cylindrical shaft part, on the upper end of which the actuating button 7 is fastened and the lower end of which opens into a hollow cylindrical part which is open at the bottom.
- the second plunger part 9 is guided in a vertical bore in FIG. 1 in the mounting and guide body 1 in the vertical direction and has an enlarged outer diameter at its lower end which is larger than the inner diameter of the bore. This second part is hollow on the inside.
- the two plunger parts 8 and 9 are drawn together by a prestressed spring 10 which is fastened to the plunger parts 8 and 9 by means of pins 16 and 17, so that the lower end face of the plunger part 8 presses against the upper end face of the plunger part 9.
- the plunger part 8 is enclosed by an annular switching plate in such a way that the switching plate and the switching plunger part are displaceable relative to one another in the vertical direction (FIG. 1), but that they are moved together in the event of a displacement in the horizontal direction.
- the outside diameter of this switching plate is slightly smaller than the diagonal of the square formed by the switching elements 2a ... 5a, so that the switching plate is located in the middle between the switching elements in the rest position.
- the outer edge of this table top is on its underside rounded.
- the switch plate can be moved in level 6 or on the top of the assembly and guide body 1, 3ie runs parallel to level 6 and slightly above it.
- a spring 12 is arranged between the switch plate 11 and a plate 13 located above it, which is fixed in the vertical direction by a ring 14. The spring is biased so that the plate 11 is pressed down. The bias of this spring 12 is, however, less than that of the spring 10.
- a fifth switch 15 is fastened to the assembly and guide body 1, in such a way that its switching element 15a is actuated when the plunger part 9 is moved downward.
- the plunger part 8 When the user pushes the actuator down, i.e. perpendicular to the plane in which the switching plate 11 is displaceable, the plunger part 8 is moved downward against the force of the spring 12 and with it the lower plunger part 9 until its outer surfaces actuate the switching element 15a. The plunger part 8 is pushed through the switch plate 11. The two plunger parts 8 and 9 do not change their mutual position.
- the spring 12 returns the coordinate switch to its rest position when the user releases the actuator 7.
- the plunger part 9 does not move while the plunger part 8 tilts, so that its lower end face only touches the end surface of the lower plunger part facing it at one point.
- the shift plate 11 not tilted because its inner diameter is slightly larger than the outer diameter of the plunger part 8 at the relevant point and because / the spring 12 with its underside against the side of the microswitches 2 ... 5 provided with switching elements or against the parallel to it Surface of the guide body 1 presses.
- a switching element is passed over (directions a ... d in FIG.
- a simple assembly of several coordinate switches according to the invention can be achieved by lengthening the assembly and guide body 1, the coordinates switches are to be offset against each other in the longitudinal direction of this body. It is not desirable in every application that two switches, for example switches 2a and 5a, are actuated simultaneously when the actuating member is moved. This can be prevented by providing, in parallel to level 6 and above this level, a shift gate 18 indicated in dashed lines in FIG. 1, which only has recesses running in the direction of arrows a, b, c and d, in which the stem of the tappet part 8 is guided when moving the actuator 7.

Abstract
Die Erfindung betrifft eine Schalteranordnung (Koordinatenschalter), mit der vier Schalter durch Verschieben eines Betätigungsorgans in zwei zueinander senkrechten Richtungen sowie ein fünfter Schalter durch Verschieben in einer dazu senkrechten Richtung betätigt werden.The invention relates to a switch arrangement (coordinate switch) with which four switches are actuated by moving an actuator in two mutually perpendicular directions and a fifth switch by displacing in a direction perpendicular thereto.
Description
Die Erfindung betrifft eine Schalteranordnung mit einem Betätigungsorgan, bei dessen seitlicher Verschiebung wenigstens einer von mehreren Schaltern betätigbar ist und das beim Eindrücken entgegen der Kraft einer Feder über einen Schaltstößel auf einen weiteren Schalter einwirkt.The invention relates to a switch arrangement with an actuating member, the lateral displacement of which at least one of a plurality of switches can be actuated and which acts on a further switch when pressed against the force of a spring via a switching plunger.
Derartige Schalteranordnungen können beispielsweise zur Steuerung der Antriebsmotoren für eine Tischplatte bei einem Röntgenuntersuchungsgerät benutzt werden, wobei zweckmäßigerweise die Betätigungsrichtung und die Richtung, in die die Tischplatte durch Betätigung der Schalteranordnung verschoben wird, zusammenfallen. Durch die Betätigung des weiteren Schalters kann dann noch eine weitere, von der Tischplattenverschiebung unabhängige Funktion geschaltet werden.Such switch arrangements can be used, for example, to control the drive motors for a table top in an X-ray examination apparatus, the direction of actuation and the direction in which the table top is displaced by actuating the switch arrangement expediently coinciding. By actuating the further switch, a further function that is independent of the table top displacement can then be switched.
Bei einer bekannten Schaltervorrichtung der eingangs genannten Art sind um den Stößel herum vier Mikroschalter angeordnet, und zwar so, daß ihre mit einem Schaltglied versehenen Seiten dem zylindrischen Stößel zugewandt sind, der bei einer seitlichen Verschiebung des Betätigungsorgans gegen eines der Schaltglieder drückt. Das Bauvolumen einer solchen Schalteranordnung kann dabei zwar dadurch verringert werden, daß die Mikroschalter möglichst dicht um den Schaltstößel herum angeordnet werden. Dann genügt jedoch bereits eine kleine Verschiebung des Betätigungsorgans, um einen Schaltvorgang auszulösen. Derart kurze Schaltwege sind jedoch für den Benutzer ungünstig; bei einem Röntgenuntersuchungsgerät beispielsweise, bei dem der Benutzer in der Regel Bleigummihandschuhe trägt und mit dem Daumen auf das Betätigungsorgan einwirkt, verliert der Benutzer bei derart kurzen Schaltwegen das Gefühl dafür, ob der Schalter betätigt ist oder nicht. Ein weiterer Nachteil ist, daß die Kräfte, die der Benutzer auf das Betätigungsorgan ausübt, voll von den Schaltern aufgenommen werden müssen.In a known switch device of the type mentioned, four microswitches are arranged around the plunger, in such a way that their sides provided with a switching element face the cylindrical plunger which presses against one of the switching elements when the actuating member is laterally displaced. The overall volume of such a switch arrangement can be reduced by arranging the microswitches as close as possible to the switching plunger. Then, however, a small displacement of the actuating member is sufficient to trigger a switching operation. Such short switching distances are disadvantageous for the user; in an X-ray examination device, for example, in which the user in generally wearing lead rubber gloves and acting with the thumb on the actuator, the user loses the feeling of whether the switch is actuated or not with such short switching distances. Another disadvantage is that the forces that the user exerts on the actuator must be fully absorbed by the switches.
Aufgabe der vorliegenden Erfindung ist es, eine Schalteranordnung der eingangs genannten Art so auszubilden, daß sich trotz geringen Bauvolumens hinreichend große Schaltwege ergeben. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die mit einem Schaltglied versenenen Seiten der durch seitliche Verschiebung betätigbaren Schalter in einer Ebene liegen, daß die Schaltglieder um einen in der Ebene verschiebbaren Schaltteller herum angeordnet sind, und daß der Schaltteller auf dem Schaltstößel verschiebbar angeordnet ist.The object of the present invention is to design a switch arrangement of the type mentioned at the outset in such a way that, despite the small construction volume, there are sufficiently long switching paths. This object is achieved in that the sides provided with a switching element of the switches which can be actuated by lateral displacement lie in one plane, in that the switching elements are arranged around a switching plate which is displaceable in the plane, and in that the switching plate is arranged displaceably on the switching plunger.
Nach einer bevorzugten Ausgestaltung der Erfindung ist dabei vorgesehen, daß der Schaltstößel zweiteilig ausgebildet ist, wobei der eine mit dem Schaltteller zusammenwirkende Stößelteil starr mit dem Betätigungsorgan verbunden ist und der andere auf den weiteren Schalter einwirkende Stößelteil senkrecht zu der Ebene verschiebbar ist, und daß die beiden in Achsrichtung gegeneinander versetzten Stößelteile durch eine Zugfeder mit den einander zugewandten Flächen gegeneinander gedrückt werden.According to a preferred embodiment of the invention, it is provided that the switching plunger is formed in two parts, one of the plunger parts interacting with the switching plate being rigidly connected to the actuating member and the other plunger part acting on the further switch being displaceable perpendicular to the plane, and that two pusher parts offset in the axial direction are pressed against one another by a tension spring with the surfaces facing one another.
Bei der Erfindung werden also die Schaltglieder dadurch betätigt, daß der Schaltteller sie überfährt. Die vom Benutzer auf das Betätigungsorgan ausgeübten Kräfte werden dabei nicht auf die einzelnen Schalter übertragen. Zum Betätigen des weiteren Schalters wird das Betätigungsorgan senkrecht zu der Ebene verschoben, wobei der erste Stößelteil auf den zweiten einwirkt, der in dieser Richtung geführt ist und das Schaltglied des weiteren Schalters betätigt. - Wenn hingegen das Betätigungsorgan seitlich verschoben wird, kippt der erste Stößelteil relativ zum zweiten, wobei sich letzterer nicht bewegt, wobei jedoch der Schaltteller verschoben wird, bis er wenigstens ein Schaltglied betätigt. Die Rückstellung des Betätigungsorgans erfolgt dabei mit Hilfe der unter Vorspannung stehenden Zugfeder. Bei geeigneter Auslegung dieser Zugfeder wird der von ihr ausgeübte Zug bei seitlicher Verschiebung des Betätigungsorgans nur geringfügig vergrößert, so daß die der Betätigungskraft des Benutzers entgegenwirkende (Rückstell-) Kraft bei der Verschiebung im wesentlichen konstant bleibt. Der Bedienkomfort wird dadurch wesentlich erhöht.In the invention, therefore, the switching elements are actuated in that the switch plate runs over them. The forces exerted by the user on the actuator are not transmitted to the individual switches. To actuate the further switch, the actuating member is displaced perpendicular to the plane, the first plunger partially acts on the second, which is guided in this direction and actuates the switching element of the further switch. - If, on the other hand, the actuating member is laterally displaced, the first tappet part tilts relative to the second, the latter not moving, but the indexing plate is displaced until it actuates at least one switching element. The actuator is reset using the tension spring under tension. With a suitable design of this tension spring, the tension exerted by it is only slightly increased when the actuating member is laterally displaced, so that the (restoring) force counteracting the actuating force of the user remains essentially constant during the displacement. The ease of use is significantly increased.
Die Erfindung wird nachstehend anhand der Zeichnung näher erläutert. Es zeigen

- Fig. 2 eine Draufsicht auf eine derartige Schalteranordnung.
- Fig. 1 shows a side section through a switch assembly according to the invention and
- Fig. 2 is a plan view of such a switch arrangement.
Die in der Zeichnung dargestellte Schalteranordnung - ein sogenannter Koordinaten schalter - weist einen Montage- und Führungskörper 1 auf, an dem fünf Mikroschalter befestigt sind. Vier davon, nämlich die Mikroschalter 2, 3, 4 und 5 sind so angeordnet, daß ihre Schaltglieder 2a, 3a, 4a und 5a auf den Eckpunkten eines Quadrates liegen und ihre mit den Schaltgliedern versehenen Seiten eine Ebene bilden, die in Fig. 2 parallel zur Zeichenebene und in Fig. 1 senkrecht zur Zeichenebene verläuft, wobei in Fig. 1 die horizontal verlaufende Schnittlinie mit der Zeichenebene mit 6 bezeichnet ist.The switch arrangement shown in the drawing - a so-called coordinate switch - has an assembly and
Das knopfförmig ausgebildete Betätigungsorgan 7 und der Schaltstößel befindet sich im Zentrum dieser vier Schalter. Der in Fig. 1 vertikal und in Fig. 2 senkrecht zur Zeichenebene verlaufende Schaltstößel besteht aus zwei rotationssymmetrischen Teilen 8 und 9, die in Achsrichtung hintereinander angeordnet sind. Der mit dem Betätigungsorgan 7 verbundene Stößelteil 8 besitzt einen zylindrischen Schaftteil, auf dessen oberem Ende der Betätigungsknopf 7 befestigt ist und dessen unteres Ende in einen hohlzylinderförmigen Teil einmündet, der nach unten offen ist. Der zweite Stößelteil 9 ist in einer in Fig. 1 vertikal verlaufenden Bohrung im Montage- und Führungskörper 1 in vertikaler Richtung geführt und besitzt an seinem unteren Ende einen vergrößerten Außendurchmesser, der größer ist als der Innendurchmesser der Bohrung. Dieser zweite Teil ist innen hohl. Die beiden Stößelteile 8 und 9 werden durch eine vorgespannte Feder 10 zusammengezogen, die mit Stiften 16 und 17 an den Stoßelteilen 8 und 9 befestigt ist, so daß die untere Stirnfläche des Stößelteils 8 gegen die obere Stirnfläche des Stößelteils 9 drückt.The button-
Der Stößelteil 8 wird von einem ringförmigen Schaltteller derart umschlossen, daß der Schaltteller und der Schaltstößelteil in vertikaler Richtung (Fig. 1) zueinander verschiebbar sind, daß sie jedoch bei einer Verschiebung in horizontaler Richtung zusammen bewegt werden. Der Außendurchmesser dieses Schalttellers ist etwas geringer als die Diagonale des durch die Schaltglieder 2a...5a gebildeten Viereckes, so daß sich der Schaltteller in der Ruhestellung in der Mitte zwischen den Schaltgliedern befindet. Der äußere Rand dieses Schalttellers ist auf seiner Unterseite verrundet. Der Schaltteller ist in der Ebene 6 bzw. auf der Oberseite des Montage- und Führungskörpers 1 verschiebbar, 3ie parallel zur Ebene 6 und geringfügig oberhalb dieser verläuft.The plunger part 8 is enclosed by an annular switching plate in such a way that the switching plate and the switching plunger part are displaceable relative to one another in the vertical direction (FIG. 1), but that they are moved together in the event of a displacement in the horizontal direction. The outside diameter of this switching plate is slightly smaller than the diagonal of the square formed by the
Eine Feder 12 ist zwischen dem Schaltteller 11 und einem darüber befindlichen Teller 13 angeordnet, der durch einen Ring 14 in vertikaler Richtung fixiert ist. Die Feder ist so vorgespannt, daß der Teller 11 nach unten gedrückt wird. Die Vorspannung dieser Feder 12 ist jedoch geringer als die der Feder 10.A spring 12 is arranged between the
Unterhalb der vier Schalter 2...5 ist ein fünfter Schalter 15 an dem Montage- und Führungskörper 1 befestigt, und zwar derart, daß bei einer Verschiebung des Stößelteils 9 nach unten sein Schaltglied 15a betätigt wird.Below the four switches 2 ... 5, a
Wenn der Benutzer das Betätigungsorgan nach unten, d.h. senkrecht zu der Ebene, in der der Schaltteller 11 verschiebbar ist, drückt, wird der Stößelteil 8 entgegen der Kraft der Feder 12 nach unten verschoben und mit ihm der untere Stößelteil 9, bis dessen Außenflächen das Schaltglied 15a betätigen. Der Stößelteil 8 wird dabei durch den Schaltteller 11 hindurchgeschoben. Die beiden Stößelteile 8 und 9 verändern ihre gegenseitige Lage nicht. Die Feder 12 bringt den Koordinatenschalter in seine Ruhestellung zurück, wenn der Benutzer das Betätigungsorgan 7 losläßt.When the user pushes the actuator down, i.e. perpendicular to the plane in which the
Wenn der Benutzer das Betätigungsorgan seitlich verschiebt, d.h. senkrecht zur Achse des Schaltstößels 8, 9, verschiebt sich der Stößelteil 9 nicht, während der Stößelteil 8 kippt, so daß seine untere Stirnfläche die ihr zugewandte Stirnfläche des unteren Stößelteils nur noch an einer Stelle berührt. Durch dieses Kippen wird der Schaltteller 11 nicht mitgekippt, weil sein Innendurchmesser etwas größer ist als der Außendurchmesser des Stößelteils 8 an der betreffenden Stelle und weil/die Feder 12 ihn mit seiner Unterseite gegen die mit Schaltorganen versehenen Seiten der Mikroschalter 2...5 bzw. gegen die dazu parallele Oberfläche des Führungskörpers 1 drückt. Er wird jedoch seitlich verschoben, wobei je nach der Richtung der auf das Betätigungsorgan 7 ausgeübten Kraft ein Schaltglied überfahren wird (Richtungen a...d in Fig. 2) oder zwei Schaltglieder (Richtungen e...h), wodurch gegebenenfalls weitere Schaltfunktionen ausgeübt werden. Die Kraft, mit der dabei auf die Schalter bzw. ihre Schaltglieder eingewirkt wird, ist von der vom Benutzer aufgebrachten Kraft unabhängig und entspricht der Vorspannung der Feder 12. Weil der Stößelteil 8 gekippt wird und weil die Schaltglieder 2a...5a ohne weiteres vom Schaltteller überfahren werden können, ergeben sich fühlbare Schaltwege, was für die Benutzung von Vorteil ist.If the user moves the actuator laterally, ie perpendicular to the axis of the switching plunger 8, 9, the plunger part 9 does not move while the plunger part 8 tilts, so that its lower end face only touches the end surface of the lower plunger part facing it at one point. By this tilting the
Beim Kippen des Stößelteils 8 wird die Feder 10 geringfügig gedehnt, was die Vorspannung geringfügig vergrößert. Da diese Vergrößerung aber wesentlich kleiner ist als die Vorspannung selbst, bleibt die vom Benutzer zum Kippen des Stößelteils 8 auf das Betätigungsorgan 7 aufzubringende Kraft, im wesentlichen konstant, was ebenfalls zum Bedienungskomfort beiträgt. Die Rückstellung in die Ruhelage nach dem Loslassen des Betätigungsorganes 7 wird im wesentlichen durch die Feder 10 bewirkt, die sich zusammenzieht, bis sich die einander zugewandten Stirnflächen der Stößelteile 8 und 9 wieder vollständig berühren.When the tappet part 8 is tilted, the
Ein einfacher Zusammenbau mehrerer erfindungsgemäßer Koordinatenschalter läßt sich durch Verlängerung des Montage-und Führungskörpers 1 erreichen, wobei die Koordinatenschalter in Längsrichtung dieses Körpers gegeneinander zu versetzen sind. Nicht in jedem Anwendungsfall ist es erwünscht, daß beim Verschieben des Betätigungsorganes zwei Schalter gleichzeitig, z.B. die Schalter 2a und 5a, betätigt werden. Dies läßt sich dadurch verhindern, daß parallel zur Ebene 6 und oberhalb dieser Ebene eine in Fig. 1 gestrichelt angedeutete Schaltkulisse 18 vorgesehen ist, die lediglich in Richtung der Pfeile a, b, c und d verlaufende Ausnehmungen aufweisen, in denen der Schaft des Stößelteils 8 beim Verschieben des Betätigungsorganes 7 geführt ist.A simple assembly of several coordinate switches according to the invention can be achieved by lengthening the assembly and
