Description

Verriegelungsvorrichtung für einen Schieber Die Erfindung betrifft eine Verriegelungsvorrichtung eines in einem Gehäuse zwischen zwei Schaltstellungen beweglich angeordneten und in Bewegungsrichtung federbelasteten Schiebers mit einem am Gehäuse angeordneten und mit einem Ende in eine herzförmige Führungsnut des Schiebers eingreifenden beweglichen Verriegelungsorgan, welches an einem von zwei die Nut in zwei Hälften aufteilenden Rastpunkten anliegt.Locking device for a slide The invention relates to a locking device one in a housing between two switching positions movably arranged and spring-loaded in the direction of movement slide with a arranged on the housing and with one end in a heart-shaped guide groove of the slide engaging movable locking member, which on one of two the groove rests in two halves dividing locking points.

Derartige Vorrichtungen eignen sich für alle mittels eines Druckknopfes oder mittels Tasten betätigte Schalteinrichtungen, wie sie z. B. für elektrische Tastenschalter, Füllhalter mit einziehbarer Spitze oder Kugelschreiber verwendet werden. Es sind stets Geräte, bei welchen ein federbelasteter Schieber lediglich durch Eindrücken in gleicher Richtung aus der einen in die andere von zwei Grundstellungen bewegt wird.Such devices are suitable for all by means of a push button or switching devices operated by means of buttons, such as those used, for. B. for electrical Used key switches, retractable nib fountain pens, or ballpoint pens will. There are always devices in which a spring-loaded slide only by pressing in the same direction from one of the two basic positions into the other is moved.

Es sind bereits zahlreiche Verriegelungsvorrichtungen bekannt, bei welchen der federbelastete Schieber mit einer herzförmigen Führungsnut versehen ist, die das Ende eines am Gehäuse beweglich angeordneten Haltestiftes aufnimmt. Der Führungsweg weist wenigstens zwei V-förmige Abschnitte auf, deren Spitzen im wesentlichen parallel zur Verschiebungsachse in gleiche Richtung zeigen, und welche als Rastpunkte für den Haltestift dienen. Somit bestimmen sie die beiden Grundstellungen des beweglichen und federbelasteten Schiebers.There are already numerous locking devices known in which the spring-loaded slide is provided with a heart-shaped guide groove which receives the end of a retaining pin movably arranged on the housing. The guide path has at least two V-shaped sections, the tips of which in the show essentially parallel to the axis of displacement in the same direction, and which serve as locking points for the retaining pin. Thus they determine the two basic positions of the movable and spring-loaded slide.

Bei diesen bekannten Vorrichtungen ist der Haltestift am Gehäuse derart angeordnet, daß er beim Durchlaufen der Führungsnut parallel zu sich verschoben wird. Ferner ist die Führungsnut derart ausgebildet, daß sie vom Haltestift stets in der gleichen Richtung durchlaufen wird. Dies wird durch einen asymmetrischen Verlauf der herzförmigen Steuerkurve bzw. durch eine sich ändernde Tiefe der Nut erreicht, wobei im letzteren Fall in der Nut angeordnete Rampen bzw. Anschlagkanten eine Rücklaufbewegung des Haltestiftes verhindern.In these known devices, the retaining pin on the housing is such arranged that it is displaced parallel to itself when passing through the guide groove will. Furthermore, the guide groove is designed such that it is always from the retaining pin is traversed in the same direction. This is due to an asymmetrical Course of the heart-shaped control curve or due to a changing depth of the groove achieved, in the latter case arranged ramps or stop edges in the groove prevent reverse movement of the retaining pin.

Bei diesen Vorrichtungen muß der Haltestift auf einem bezüglich des Gehäuses beweglichen, im allgemeinen zu diesem schwenkbaren Arm angebracht werden, so daß seine Parallelverschiebung stets gewährleistet ist.In these devices, the retaining pin must be on a relative to the Movable housing, generally attached to this pivotable arm, so that its parallel shift is always guaranteed.

Insbesondere für Kugelschreiber wurde ferner vorgeschlagen, an Stelle eines Stiftes eine Kugel vorzusehen, die einerseits bei Betätigung des Schiebers die Herzkurve durchläuft und andererseits in einer im Gehäuse angeordneten Nut beweglich gelagert ist.In particular for ballpoint pens it has also been suggested in place a pin to provide a ball that on the one hand when the slide is actuated the heart curve passes through and on the other hand movable in a groove arranged in the housing is stored.

Mit der Erfindung wird eine weitere Möglichkeit der Ausbildung des Verriegelungsorgans vorgeschlagen, durch welche die Herstellung und die Montage derartiger Vorrichtungen, die in der Regel in großen Mengen produziert werden, vereinfacht werden.With the invention, a further possibility of training the Proposed locking member through which the manufacture and assembly such devices, which are usually produced in large quantities, simplified will.

Nach derErfindung ist die Verriegelungsvorrichtung derart ausgebildet, daß das Verriegelungsorgan mit einem Ende kippbar in einer Öffnung des Schaltergehäuses gelagert ist und mit dem anderen Ende durch eine die freie Kippbewegung des Verriegelungsorgans zulassende Feder gegen den Boden der im Schieber angeordneten Nut gedrückt wird. Bei einer derart einfachen Vorrichtung ist es nicht notwendig, daß das Verriegelungsorgan stets parallel zu sich selbst verschoben werden muß, dagegen kann es ungehindert verschwenkt oder gekippt werden, wenn sein Ende die Führungsnut durchläuft. Hierdurch entfällt der bisher übliche Tragarm für das Verriegelungsorgan.According to the invention, the locking device is designed such that that the locking member can be tilted with one end in an opening of the switch housing is mounted and with the other end by a free tilting movement of the locking member permitting spring is pressed against the bottom of the groove arranged in the slide. With such a simple device, it is not necessary that the locking member must always be shifted parallel to itself, on the other hand it can be moved unhindered be pivoted or tilted when its end passes through the guide groove. Through this the previously usual support arm for the locking member is no longer necessary.

Als Verriegelungsorgan kann ein geradliniger; zylindrischer Bolzen Verwendung finden, dessen eines Ende in die Führungsnut eingreift, der mit seinem mittleren Bereich durch die Öffnung des Schaltergehäuses hindurchtritt und auf dessen anderes Ende die mit dem Gehäuse verbundene Feder einwirkt. Die Anordnung ist derart, daß der Bolzen wenigstens in einer zur Achse des Schiebers senkrechten Ebene eine freie Kippbewegung durchführen kann.As a locking member, a straight line; cylindrical bolt Find use, one end of which engages in the guide groove with his middle area passes through the opening of the switch housing and on its the other end acts on the spring connected to the housing. The arrangement is such that the bolt is at least one in a plane perpendicular to the axis of the slide can perform free tilting movement.

Bei einer zweckmäßigen Ausführungsform des Erfindungsgegenstandes ist die auf das Verriegelungsorgan wirkende Feder mit dem Gehäuse mit Hilfe der auf den beweglichen Schieber wirkenden Feder kraftschlüssig verbunden. Hierdurch erübrigt es sich, diese Feder in einem weiteren Arbeitsgang mit dem Gehäuse zu verbinden, wodurch wiederum die Herstellungskosten, -mittel und -zeit herabgesetzt werden können.In an expedient embodiment of the subject matter of the invention is the one on the locking member acting spring with the housing positively connected with the aid of the spring acting on the movable slide. This eliminates the need for this spring in a further operation with the housing to connect, which in turn reduces manufacturing costs, resources and time can be.

Während die üblichen, bisher bekannten Steuernuten einen rechteckigen Querschnitt aufwiesen, wird mit der Erfindung ferner vorgeschlagen, den zentralen Kern der herzförmigen Steuerkurve mit nach oben und innen geneigten Begrenzungs- und Führungswänden zu versehen. Da nämlich der als Verriegelungsorgan wirkende Haltestift im Gegensatz zu den bekannten Verriegelungsvorrichtungen nicht zu sich selbst verschoben wird, sondern bei Durchlaufen der Steuernut in die eine oder andere Richtung geneigt wird, wird bei dieser Ausbildung eine möglichst gute, spielfreie Führung des Verriegelungsorgans ermöglicht. Die Steuerkurve kann in an sich bekannter Weise einen symmetrischen oder asymmetrischen Verlauf besitzen. Die asymmetrische Form ist dann zu bevorzugen, wenn der Raumbedarf in Längsrichtung der Vorrichtung möglichst klein gehalten werden muß.While the usual, previously known control grooves are rectangular Had cross-section, the invention also proposes the central Core of the heart-shaped control cam with upward and inward inclined limiting and guide walls. There namely the retaining pin acting as a locking member in contrast to the known locking devices not shifted towards itself is, but inclined in one direction or the other when passing through the control groove is, in this training, the best possible backlash-free guidance of the locking member enables. The control curve can be symmetrical in a manner known per se or have an asymmetrical course. The asymmetrical shape is then to be preferred, if the space requirements in the longitudinal direction of the device are kept as small as possible got to.

Der Gegenstand der Erfindung ist an Hand eines bevorzugten Ausführungsbeispiels, welches in den F i g. 1 bis 4 der Zeichnung dargestellt ist, nachstehend im einzelnen erläutert. Es zeigt F i g. 1 eine perspektivische, teilweise aufgebrochene Teilansicht einer für einen tastenbetätigten elektrischen Schalter verwendeten Vorrichtung nach der Erfindung, F i g. 2 eine Aufsicht der Schaltstange des Schalters nach F i g. 1, F i g. 3 einen Schnitt nach der Linie 111-III in F i g. 2 und F i g. 4 einen Schnitt nach der Linie IV-IV in Fig. 3.The subject matter of the invention is based on a preferred embodiment, which in the F i g. 1 to 4 of the drawings, below in detail explained. It shows F i g. 1 is a perspective, partially broken away partial view a device used for a key operated electrical switch of the invention, FIG. 2 shows a plan view of the switching rod of the switch according to FIG. 1, Fig. 3 shows a section along the line III-III in FIG. 2 and F i g. 4 one Section along the line IV-IV in FIG. 3.

Der in F i g. 1 dargestellte elektrische Schalter weist eine mit beweglichen Kontakten versehene Schaltstange 2 auf, die in einem Gehäuse 4 verschiebbar gelagert ist, das mit Anschlüssen 6 verbundene, feststehende Kontakte trägt. Die das Ende der Schaltstange umgebende Feder 8 stützt sich einerseits gegen das Gehäuse und andererseits gegen die Taste 10 ab, so daß die Schaltstange ständig mit einer bezüglich des Gehäuses nach außen gerichteten Kraft beaufschlagt ist.The in F i g. 1 shown electrical switch has a movable Contacts provided switch rod 2, which is slidably mounted in a housing 4 is, which carries fixed contacts connected to terminals 6. The end the spring 8 surrounding the shift rod is supported on the one hand against the housing and on the other hand against the key 10, so that the switch rod is constantly with a relation the housing is acted upon by an outward force.

Die Schaltstange 2 ist mit einer Steuernut 12 von geschlossener symmetrischer oder asymmetrischer Form versehen, welche zwei als Rasten dienende Spitzen 14 und 16' aufweist. Die Steuernut hat in Abhängigkeit vom Kurvenverlauf eine unterschiedliche Tiefe, wobei mehrere Rampen und Stufen 18, 18', 18" gebildet werden, wodurch der Verriegelungsstift gezwungen wird, die Nut stets in Richtung des Pfeiles 20 zu durchlaufen. Der Stift 22 wird mit Hilfe einer am Gehäuse 2 angeordneten Blattfeder 24, welche auf diesen eine Kraft in Richtung des Pfeiles 26 (F i g. 3) ausübt, gegen den Boden der Steuerkurve gedrückt.The shift rod 2 is provided with a control groove 12 of closed symmetrical or asymmetrical shape, which has two tips 14 and 16 'serving as notches. The control groove has a different depth depending on the course of the curve, with several ramps and steps 18, 18 ', 18 "being formed, whereby the locking pin is forced to always pass through the groove in the direction of arrow 20. The pin 22 is with the help of a on the housing 2 arranged leaf spring 24, which exerts a force on it in the direction of arrow 26 (Fig. 3), pressed against the bottom of the control cam.

Die Blattfeder weist in der Nähe ihres freien Endes mindestens einen zur Richtung des Pfeiles 26 etwa lotrechten, ebenen Flächenabschnitt auf, gegen welchen sich das obere Ende des Bolzens 22 abstützt.The leaf spring has at least one near its free end to the direction of the arrow 26 approximately perpendicular, flat surface section on, against which the upper end of the bolt 22 is supported.

Der Bolzen 22 ist in der öffnung 28 des Gehäuses schwenkbar angeordnet. Die öffnung ist derart ausgebildet, daß der Bolzen in einer zur Verschiebungsachse senkrechten Ebene frei schwenken kann, wenn sein unteres Ende die Steuernut 12 durchläuft. In F i g. 4 ist der Bolzen in Schräglage dargestellt, welche er einnimmt, wenn sich sein unteres Ende beispielsweise in der in F i g. 2 bezeichneten Stellung 30 befindet. In der Ebene parallel zur Verschiebungsachse (F i g. 3) hat der Bolzen in der Öffnung 28 dagegen nur eine geringe Kippfreiheit, da die Breite der Öffnung 28 in Richtung dieser Achse nur etwas größer als der Durchmesser des Bolzens ist. Zweckmäßigerweise hat also die öffnung 28 eine im wesentlichen rechteckige Form und weist vorzugsweise abgerundete Seitenränder 32 auf.The bolt 22 is pivotably arranged in the opening 28 of the housing. The opening is designed in such a way that the bolt is in a direction relative to the axis of displacement can pivot freely in the vertical plane when its lower end passes through the control groove 12. In Fig. 4 the bolt is shown in an inclined position, which it assumes when its lower end, for example, in the one shown in FIG. 2 designated position 30 is located. In the plane parallel to the axis of displacement (FIG. 3), the bolt is in the opening 28, on the other hand, only a slight freedom of tilting, since the width of the opening 28 in the direction this axis is only slightly larger than the diameter of the bolt. Appropriately the opening 28 thus has an essentially rectangular shape and preferably has rounded side edges 32.

Die erfindungsgemäße Vorrichtung hat folgende Wirkungsweise: Wenn sich die Schaltstange 2 in ihrer eingedrückten Schaltstellung gemäß F i g. 3 befindet, nimmt das untere Ende des Bolzens 22 in der vertieften Steuernut 12 die Stellung 34 (F i g. 2) ein und hält die Schaltstange gegen die Wirkung der Feder 8 in dieser Stellung, wobei es in die der Spitze 16 gegenüberliegende Rast 16' des zentralen Kerns 36 eingreift. In dieser Stellung klemmt sich der Bolzen 22 gegen die Ränder der Öffnung 28, wobei das für den Einbau notwendige Spiel die in F i g. 3 dargestellte Schrägstellung bewirkt.The device according to the invention has the following mode of operation: If the shift rod 2 is in its pushed-in shift position according to FIG. 3 is located takes the lower end of the bolt 22 in the recessed control groove 12 the position 34 (Fig. 2) and holds the shift rod against the action of the spring 8 in this Position, with it in the notch 16 'opposite the tip 16 of the central Kerns 36 engages. In this position, the bolt 22 clamps against the edges of the opening 28, the play necessary for the installation being as shown in FIG. 3 shown Causes inclination.

Beim Eindrücken der Taste 10 verhindert die Stufe 18", daß sich -das untere Ende des Bolzens nach rückwärts bewegt, so daß der Bolzen die Nut in Richtung der Umlaufbewegung entsprechend dem Pfeil 20 durchläuft und schließlich geführt von der Schrägfläche 18' der Spitze 16 aus der Stellung 34 in die Stellung 38 gelangt, wobei er sich bedingt durch die Form der Öffnung 28 seitlich neigen kann.When the button 10 is pressed, the level 18 "prevents the lower end of the bolt moves backwards so that the bolt is facing the groove the orbital movement according to the arrow 20 passes and finally performed moves from the inclined surface 18 'of the tip 16 from the position 34 to the position 38, it can incline to the side due to the shape of the opening 28.

Beim Loslassen der Taste läuft die Schaltstange 2 unter Einwirkung der Feder 8 zurück, so daß das untere Ende des Bolzens 22 den gesamten (in F i g. 2) oberen Abschnitt der Steuerkurve durchläuft und in die Rast 14 der Steuerkurve gelangt, welche die zweite Grundstellung der Schaltstange bestimmt. Der Bolzen, dessen Schrägstellung sich beim Durchlaufen der ganzen Wegstrecke verändert hat, nimmt wieder eine Lage ein, die der in F i g. 2 dargestellten entspricht, und verriegelt die Schaltstange gegen die Wirkung der Feder B.When the button is released, the shift rod 2 runs under the influence the spring 8 back so that the lower end of the bolt 22 the entire (in F i g. 2) passes through the upper section of the control cam and into the detent 14 of the control cam which determines the second basic position of the shift rod. The bolt, the inclination of which has changed when you walked the entire route, again assumes a position that the one shown in FIG. 2 shown corresponds, and locked the shift rod against the action of spring B.

Der Boden der Steuernut ist über den gesamten vorerwähnten oberen Abschnitt rampenartig ausgebildet und endet in einer Stufe 18, die verhindert, daß sich der Bolzen 22 beim erneuten Eindrücken der Taste 10 zurückbewegt.The bottom of the control groove is over the entire aforementioned upper Section formed like a ramp and ends in a step 18 that prevents the bolt 22 moves back when the button 10 is pushed in again.

Wenn das untere Ende des Bolzens den Weg des unteren Abschnitts der Steuerkurve (F i g. 2) zurücklegt, neigt sich der Bolzen erneut, jedoch in entgegengesetzter Richtung, wobei er in Stellung 30 seine in F i g. 4 dargestellte, stärkste Schräglage einnimmt. Am Ende des unteren Abschnittes der Steuerkurve 12 zwingt eine weitere Stufe 18" im Boden der Steuernut das untere Ende des Bolzens, in seine Stellung 34 zurückzukehren.When the lower end of the bolt is the way of the lower section of the When the control curve (FIG. 2) is covered, the bolt tilts again, but in the opposite direction Direction, where he in position 30 his in F i g. 4 shown, strongest inclination occupies. At the end of the lower section of the control cam 12 forces another Step 18 "in the bottom of the control groove the lower end of the bolt in its position 34 to return.

Bei einer zweckmäßigen Ausführungsform der Erfindung wird die Blattfeder 24 von der Feder 8 gegen das Gehäuse 4 gedrückt, wobei sie mittels einer zwischen dem Gehäuse und der Schaltstange eingreifenden, umgelegten Nase 40 in ihrer Lage fixiert ist. Hierdurch erübrigt sich die Befestigung mit einer Schraube, Niet od. dgl.In an advantageous embodiment of the invention, the leaf spring 24 pressed by the spring 8 against the housing 4, wherein it by means of an between the housing and the shift rod engaging, folded nose 40 in their position is fixed. This eliminates the need for fastening with a screw, rivet or the like. like

Da der Bolzen im Gegensatz zu den bekannten Verriegelungsvorrichtungen dieser Art nicht parallel zu sich verschoben wird, sondern beim Durchlaufen der Steuernut verschiedene Schrägstellungen einnimmt, ist der zentrale Kern 36 der herzförmigen Steuerkurve vorteilhafterweise mit geneigten Flanken versehen, die eine gute Führung des Bolzens ermöglichen (F i g. 4). Die üblichen, bisher bekannten Steuerkurven besitzen dagegen senkrechte Flanken, die die freie Kipp- oder Schwenkbewegung des Bolzens einer Vorrichtung nach der Erfindung verhindern oder zumindest behindern würden.Because the bolt in contrast to the known locking devices not parallel of this kind is shifted to himself, but when The central one is when the control groove assumes different inclinations Core 36 of the heart-shaped control cam is advantageously provided with inclined flanks, which allow good guidance of the bolt (Fig. 4). The usual, previously known Control cams, on the other hand, have vertical flanks that allow the free tilting or swiveling movement prevent or at least hinder the bolt of a device according to the invention would.

Die Steuerkurve wird zweckmäßigerweise unmittelbar beim Formen oder Gießen der gesamten Schaltstange aus Kunststoff ausgespart.The control curve is expediently directly when shaping or The entire shift rod is molded from plastic.
