Description

Die Erfindung betrifft eine Schalteranordnung nach dem Oberbegriff des Hauptanspruchs.The invention relates to a switch arrangement according to the preamble of the main claim.

Eine solche Schalteranordnung ist im wesentlichen aus der DE-B-1 227 113 bekannt. Allerdings ist dabei in zwei Ebenen je ein Schaltteller vorgesehen, der je zwei Schaltglieder betätigt. Die bekannte Schalteranordnung gestattet bei relativ kompaktem Aufbau relativ lange Schaltwege, weil die Schaltteller die Schaltglieder überfahren können, ohne daß dabei von dem Betätigungsorgan bzw. dem Schaltstößel unzulässig hohe Kräfte auf die einzelnen Schalter einwirken. Solche relativ langen Schaltwege sind für den Benutzer in verschiedenen Fällen günstig. Bei einem Röntgenuntersuchungsgerät beispielsweise, bei dem der Benutzer in der Regel Bleigummihandschuhe trägt und mit dem Daumen auf das Betätigungsorgan einwirkt, würde der Benutzer bei kurzen Schaltwegen das Gefühl dafür verlieren, ob der Schalter betätigt ist oder nicht.Such a switch arrangement is essentially known from DE-B-1 227 113. However, an indexing plate is provided in two levels, which actuates two switching elements. The known switch arrangement allows relatively long switching distances with a relatively compact structure, because the switching plates can drive over the switching elements without impermissibly high forces acting on the individual switches from the actuating member or the switching plunger. Such relatively long switching distances are favorable for the user in various cases. In the case of an X-ray examination apparatus, for example, in which the user generally wears lead rubber gloves and acts on the actuating element with the thumb, the user would lose the feeling of whether the switch is actuated or not with short switching paths.

Die bekannte Schalteranordnung enthält eine Bodenplatte mit kugeligen Ausnehmungen, in die eine auf dem Schaltstößel verschiebbare Gleitbuchse mit Federkraft gedrückt werden kann, so daß die Schalteranordnung in verschiedenen Schalterstellungen einrastet.The known switch arrangement contains a base plate with spherical recesses into which a sliding bush which can be displaced on the switching plunger can be pressed with spring force, so that the switch arrangement engages in different switch positions.

Aufgabe der vorliegenden Erfindung ist es, eine Schalteranordnung der eingangs genannten Art so auszubilden, daß sich einerseits trotz geringem Bauvolumens hinreichend große Schaltwege ergeben und andererseits eine selbsttätige Rückstellung des Betätigungsorgans erfolgt.The object of the present invention is to design a switch arrangement of the type mentioned at the outset such that, on the one hand, there are sufficiently large switching paths despite the small construction volume and, on the other hand, the actuator is automatically reset.

Diese Aufgabe wird durch die im Kennzeichen des Hauptanspruchs angegebenen Maßnahmen gelöst.This object is achieved by the measures specified in the characterizing part of the main claim.

Zum Betätigen des ersten Schalters wird das Betätigungsorgan senkrecht zu der Ebene verschoben, wobei der erste Stößelteil auf den zweiten einwirkt, der in dieser Beätigungsrichtung geführt ist und das Schaltglied des ersten 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 durch Überfahren betätigt, so daß die vom Benutzer auf das Betätigungsorgan ausgeübten Kräfte nicht auf die einzelnen Schalter übertragen werden. 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.To actuate the first switch, the actuating member is displaced perpendicular to the plane, the first plunger part acting on the second, which is guided in this actuating direction and actuates the switching element of the first switch. If, on the other hand, the actuating member is moved laterally, the first tappet part tilts relative to the second, the latter not moving, but the shifting plate is displaced until it actuates at least one switching member by driving over it, so that the forces exerted by the user on the actuating member are not can be transferred to the individual switches. 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.

The invention is explained below with reference to the drawing. Show it
  • 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 Koordinatenschalter - 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 guide body 1 to 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, in Fig. 1 the horizontal intersection with the drawing plane is designated by 6.

Das knopfförmig ausgebildete Betätigungsorgan 7 und der Schaltstößel 8, 9 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 Stößelteilen 8 und 9 befestigt ist, so daß die untere Stirnfläche des Stößelteils 8 gegen die obere Stirnfläche des Stößelteils 9 drückt.The button-shaped actuator 7 and the switching plunger 8, 9 is located 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.

Der Stößelteil 8 wird von einem ringförmigen Schatttetter 11 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, die parallel zur Ebene 6 und geringfügig oberhalb dieser verläuft.The plunger part 8 is enclosed by an annular shading device 11 such 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 when displaced 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 rounded on its underside. The indexing plate can be moved in level 6 or on the top of the assembly and guide body 1, which runs parallel to level 6 and slightly above it.

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 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.

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 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.

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 moves the actuator down, i.e. H. 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.

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, i. H. 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 table 11 is not tilted because its inner diameter is slightly larger than the outer diameter of the plunger part 8 at the point in question and because the spring 12 with its underside against the sides of the microswitches 2 ... 5 provided with switching elements or against presses the parallel surface of the guide body 1. However, it is laterally displaced, depending on the direction of the force exerted on the actuating member 7, a switching element is passed over (directions a ... d in FIG. 2) or two switching elements (directions e ... h), which may result in further switching functions be exercised. The force with which it acts on the switches or their switching elements is independent of the force applied by the user and corresponds to the pretension of the spring 12. Because the plunger part 8 is tilted and because the switching elements 2a ... 5a easily from Switching plates can be run over, tangible switching paths result, which is advantageous for use.

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 spring 10 is stretched slightly, which increases the pretension slightly. However, since this enlargement is substantially smaller than the preload itself, the force to be applied by the user to tilt the tappet part 8 onto the actuating member 7 remains essentially constant, which also contributes to the ease of use. The return to the rest position after releasing the actuating member 7 is essentially effected by the spring 10, which contracts until the facing end faces of the tappet parts 8 and 9 completely touch again.

Ein einfacher Zusammenbau mehrerer erfindungsgemäßer Koordinatenschalter läßt sich durch Verlängerung des Montageund Führungskörpers 1 erreichen, wobei die Koordinatenschalter in Längsrichtung dieses Körpers gegeneinander zu versetzen sind. Nicht im 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 guide body 1, the coordinate switches being to be offset relative to one another in the longitudinal direction of this body. Not in every application, it is desirable that two switches at the same time, for. B. switches 2a and 5a are operated. 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.

Claims (4)

1. A switching assembly having an actuation member (7), which, when depressed against the force of a spring (12), acts upon a first switch (15) through a switching ram (8, 9), on which a switching disk (11) is arranged so as to be displaceable, which is displaced in a plane by lateral displacement of the actuation member (7) and then actuates at least one of several switching members, which are arranged around the switching disk (11) on the side of each time a further switch located in the plane, characterized in that the switching ram (8, 9) is bi-partite, one ram portion (8) cooperating with the switching disk (11) being rigidly connected to the actuation member (7) and the other ram portion (9) acting upon the first switch (15) being displaceable at right angles to the plane, and in that the two ram portions relatively offset in the axial direction are pressed against each other with the surfaces facing each other by means of a tensile spring (10).
2. A switch assembly as claimed in Claim 1, characterized in that the two ram portions (8, 9) are hollow and in that the tensile spring (10) is arranged in the interior of the two ram portions.
3. A switch assembly as claimed in any one of the preceding Claims, characterized in that a compression spring (12) is arranged between the switching disk (11) and a part (13) connected to the actuation member (7), which spring presses the switching disk (11) towards the switches (2...5).
4. A switch assembly as claimed in any one of the preceding Claims, characterized in that a switching guide (18) is arranged in a plane parallel to the plane (6), which switching guide limits the movement of the ram at right angles to its axial direction to given directions.
