Abstract

1. Connection device for two antagonistically movable members (A, B), wherein a fixed base part (1, 1a, 1b) is supported, via mutually supporting bearing elements and an interposed tension bar (3) which connects the members and is disposed at the centre of the members and of the spring (6), against a working part (2, 2a, 2b) which can be swivelled relative to said base part against the restoring force of a spring, and wherein in the course of deflection the lever arm present between the fulcrum point and the line of action of the spring is greater than zero, so that the force of the spring is simultaneously used to generate the restoring torque, characterised in that a) one of the members (A or B) has a U-shaped cross-section with diverging legs and the other member (B or A) has the form of a cap component overlapping the diverging legs from the web, b) the point of application of force of the tension bar on one member (A or B) - in the direction in which the force of the spring acts - is remote from the plane of the bearing and c) that within the free inner space formed by the spring (6) perpendicular to the longitudinal axis of the tension bar (3), said tension bar (3) can move in its undeflected position, one end of the tension bar being able to maintain the position on the undeflected longitudinal axis.

Description

Die Erfindung bezieht sich auf eine Verbindungsvorrichtung fürzwei gegeneinander bewegliche Bauteile gemäss dem Oberbegriff des Hauptanspruches.The invention relates to a connecting device for two mutually movable components according to the preamble of the main claim.

Eine gattungsbildende Einrichtung wird in der US-A-3 197 552 beschrieben. Diese bekannte Einrichtung ist für eine Antennenfixierung, z.B. für Unterseeboote, bestimmt und kann nur relativ kleine Abwinklungen ausführen. Wenn grosse Abwinklungen angestrebt werden, sind mehrere hintereinandergeschaltete Aggregate - wie zeichnerisch in der US-A-3 197 552 dargestellt - erforderlich.A generic device is described in US-A-3 197 552. This known device is for antenna fixation, e.g. for submarines, intended and can only make relatively small bends. If large angles are desired, several units connected in series, as shown in the drawing in US Pat. No. 3,197,552, are required.

Das eine Bauteil stützt sich dabei gegen ein sphärischen Trägerteil ab, und es ist eine die beiden Bauteile verbindende Zugstange vorgesehen, die im Zentrum der Bauteile angreift und im Zentrum einer Feder angeordnet ist, wobei im Auslenkungsablauf der zwischen dem Abstützpunkt und der Wirkungslinie der Feder bestehende Hebelarm grösser als 0 ist, so dass die Federkraft gleichzeitig zur Erzeugung des Rückstellmomentes ausgenutzt werden kann. Die bekannte Anordnung hat den Nachteil, dass nur kleine Abwinklungen möglich sind und dass sofort bei Auslenkung ein «Maulklaffen» eintritt, so dass bei Bauteilen, die leicht zugänglich sein müssen, Verletzungen der Bedienungspersonen auftreten können. Die bekannte Einrichtung weist weiterhin einen gleichbleibenden Hebelarm zwischen dem Abstützpunkt und dem Kraftangriffspunkt der Zugstange auf und weiterhin nur einen geringen Federspannweg, so dass keine hohen «Rückstellkräfte» erzielbar sind.One component is supported against a spherical support part, and a tie rod connecting the two components is provided, which engages in the center of the components and is arranged in the center of a spring, the existing between the support point and the line of action of the spring in the deflection process Lever arm is greater than 0, so that the spring force can be used simultaneously to generate the restoring torque. The known arrangement has the disadvantage that only small angles are possible and that a "gaping gap" occurs immediately when deflected, so that injuries to the operating personnel can occur in the case of components which must be easily accessible. The known device furthermore has a constant lever arm between the support point and the force application point of the drawbar and also only a small spring tensioning path, so that no high "restoring forces" can be achieved.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsbildende Einrichtung dahingehend zu verbessern, dass im Ruhezustand eine sehr stabile Halterung erreichbar ist und im abgewinkelten Zustand eine hohe Rückstellkraft erzielt wird.The invention has for its object to improve the generic device in such a way that a very stable holder can be reached in the idle state and a high restoring force is achieved in the angled state.

Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehre des Hauptanspruches gelöst.This object on which the invention is based is achieved by the teaching of the main claim.

Mit anderen Worten ausgedrückt, wird bei der erfindungsgemässen Vorrichtung so vorgegangen, dass die beiden Bauteile, nämlich Arbeitsteil und Trägerteil, geometrisch derart angepasste gemeinsame Berührungsflächen oder Berührungsschalen besitzen, dass diese die statischen Elemente des Keils (Einspannung, stabiler Sitz und hohe Kraftaufnahme) einerseits mit den dynamischen Elementen des nach der Initialkraftaufnahme wirksam werdenden Kugelgelenks andererseits zu besonderer Wirkweise verbinden, wobei die dynamischen Elemente des Kugelgelenks in einem elastischen Nachgeben und wieder Rückstellen mit Hilfe einer Feder in einem zwangsgeführten sicheren Bewegungsablauf ohne «Maulklaffen» der Verbindungsteile erreichen.In other words, in the device according to the invention the procedure is such that the two components, namely the work part and the support part, have geometrically adapted common contact surfaces or contact shells in such a way that the static elements of the wedge (clamping, stable fit and high force absorption) are included on the one hand On the other hand, combine the dynamic elements of the ball joint that becomes effective after the initial force is absorbed, whereby the dynamic elements of the ball joint achieve elastic resilience and reset with the help of a spring in a positively guided, safe movement without "gaping" the connecting parts.

Zusammen mit der freien Lagerung der Schalen und der speziellen Konstellation vom Kraftangriffspunkt zur Widerlagerebene, vergleichbar etwa mit einer Konstruktion - Wirkung der Schwerkraft vorausgesetzt - bei der der Schwerpunkt tief unten liegt und die Auflager (weit) oberhalb des Schwerpunktes angeordnet sind, ergeben sich zusätzliche neue Eigenschaften dieser Verbindungsvorrichtung, nämlich die Beherrschbarkeit grosser Neigungswinkel über den ganzen relevanten Bereich bis nahe 90° und nunmehr das im Bewegungsablauf doppelt wachsende Rückstellmoment - als Funktion des Winkels der Auslenkung: grösser werdender Hebelarm und wegen des bei Auslenkung zu beschreibenden sehr langen Weges doppelt steigende Federkraft - mit dem Resultat geringerer erforderlicher Federkraft und kleinerer Baugrösse der Vorrichtung, die für schwere Baukonstruktionen erst dadurch wirtschaftlich werdende Konstruktionen zulassen.Together with the free storage of the shells and the special constellation from the point of application of force to the abutment level, comparable to a construction - assuming the effect of gravity - in which the center of gravity is low and the supports (far) above the center of gravity, there are additional new ones Properties of this connecting device, namely the controllability of large angles of inclination over the entire relevant range up to close to 90 ° and now the restoring torque which increases twice in the course of the movement - as a function of the angle of the deflection: the lever arm becomes larger and, due to the very long path to be described, the spring force increases twice - With the result of lower required spring force and smaller size of the device, which only allow economical construction for heavy construction.

Schliesslich eröffnet die neue drei- bzw. die raumdimensionale Rückstellung, also in der x-, y- und z-Achse, neue Anwendungsbereiche.Finally, the new three-dimensional or spatial dimension provision, i.e. in the x, y and z axes, opens up new areas of application.

Die erfindungsgemäss definierte Vorrichtung bewirkt in der Ruhelage einen definierten, in drei Richtungen beständigen Sitz, der wegen seiner partiellen keilähnlichen Form der beiden Bauteile in seiner Wirkung einem eingespannten Träger gleicht und in der Bewegung einen definierten gesteuerten Bewegungsablauf über einen grossen Neigungswinkel mit sicherer Führung der Innenschale in der Aussenschale unter Vermeidung des gefährlichen Maulklaffens dieser Vorrichtung ermöglicht.In the rest position, the device defined according to the invention brings about a defined seat which is stable in three directions, which, due to its partial wedge-like shape of the two components, has the same effect as a clamped-in carrier and, during the movement, a defined, controlled movement sequence over a large angle of inclination with reliable guidance of the inner shell in the outer shell while avoiding the dangerous gaping mouth of this device.

Erst mit den neuen Eigenschaften einer Verbindungseinrichtung werden Forderungen, wie die der Erhöhung der passiven Sicherheit im Strassen- und Kraftverkehr, technisch wirtschaftlich realisierbar, z.B. Überlastsicherungen für kleine, mittlere und grosse Schilder und dreidimensionale automatische Repositionierung in stabilen und dennoch leichten Konstruktionen.It is only with the new properties of a connection device that demands such as increasing passive safety in road and motor traffic can be realized economically, e.g. Overload protection for small, medium and large signs and three-dimensional automatic repositioning in stable, yet lightweight constructions.

Das hohe Rückstellmoment ist in der Lage auch schwere und insbesondere lange Bauteile nach einer 90°-Auslenkung wieder aufzustellen.The high restoring torque is able to set up even heavy and especially long components after a 90 ° deflection.

Vorteilhafte Ausgestaltungen der erfindungsgemässen Einrichtung sind in den Unteransprüchen erläutert.Advantageous refinements of the device according to the invention are explained in the subclaims.

Eine wesentliche neue technische Anwendung findet die erfindungsgemässe Verbindung durch den Rückstelleffekt in Kombination mit elektrischen oder elektronischen Kontaktabgaben, die einerseits zu einer oder einer mehrfachen Meldung von Ereignissen, z.B. Gefahren, herangezogen werden können und andererseits sogar zur Steuerung von Vorgängen benutzbar sind, z.B. wenn das Objekt, wie eine Markise od. dgl., ganz oder teilweise aus der Gefährdung herausgesteuert werden soll. So ist es beispielsweise möglich, Markisen bei zu hohen Windbelastungen ganz oder schrittweise teilweise einzufahren.The connection according to the invention has an essential new technical application due to the reset effect in combination with electrical or electronic contact deliveries, which on the one hand result in one or more reports of events, e.g. Dangers that can be used and that can even be used to control processes, e.g. if the object, such as an awning or the like, is to be wholly or partially controlled out of the danger. For example, it is possible to partially or partially retract awnings in the event of excessive wind loads.

In Fig. 1 ist schematisch eine Verbindungsvorrichtung für zwei Bauteile A und B dargestellt, wobei in der nachfolgenden Erläuterung das Bauteil A als Trägerteil 1 und das Bauteil B als Arbeitsteil 2 bezeichnet sind. Das Trägerteil 1 ist mit dem Arbeitsteil 2 über eine Zugstange 3 verbunden, die mittels eines Kugelendes 4 an der Innenseite des Trägerteiles 1 anliegt, wobei in der Kegelspitze des Trägerteiles 1 Schlitze 5 ausgearbeitet sind, die eine Abwinkelung der Zugstange aus der in Fig. 1 dargestellten Lage, beispielsweise in die in Fig. 2 dargestellte Lage, ermöglichen. Innerhalb des Arbeitsteiles 2 ist eine Schraubenfeder 6 vorgesehen, die einenendes an einer entsprechenden Ringlagerfläche 7 des Arbeitsteiles 2 anliegt, anderenendes sich an der Unterseite einer Widerlagerscheibe 8 abstützt, die von der Zugstange 3 getragen wird.A connection device for two components A and B is shown schematically in FIG. 1, component A being designated as support part 1 and component B as working part 2 in the following explanation. The carrier part 1 is connected to the working part 2 via a pull rod 3, which rests on the inside of the carrier part 1 by means of a ball end 4, slots 5 being worked out in the conical tip of the carrier part 1, which angled the pull rod from that in FIG. 1 shown position, for example in the position shown in Fig. 2, allow. Provided within the working part 2 is a helical spring 6, one end of which rests on a corresponding ring bearing surface 7 of the working part 2, the other end is supported on the underside of an abutment disk 8 which is carried by the pull rod 3.

Das untere Ende des Arbeitsteiles 2 übergreift haubenartig ein glockenförmig und kegelstumpfartig ausgebildetes Bauteil des Trägerteiles 1. Das Trägerteil 1 weist bei dieser Konstruktion ein umlaufendes Widerlager 9 auf, an dem sich bei Kippbewegungen des Arbeitsteiles 2 das untere Ende der Haube 10 abstützen kann.The lower end of the working part 2 overlaps a bell-shaped and truncated cone-shaped component of the carrier part 1. In this construction, the carrier part 1 has a circumferential abutment 9, against which the lower end of the hood 10 can be supported when the working part 2 is tilted.

In der in Fig. 1 dargestellten eigentlichen Arbeitslage liegt die Haube 10 dicht dem rotationssymmetrischen Kegelstumpf 11 des Trägerteiles 1 an.In the actual working position shown in FIG. 1, the hood 10 lies tightly against the rotationally symmetrical truncated cone 11 of the carrier part 1.

Bei Krafteinwirkung auf das Arbeitsteil 2, beispielsweise in Richtung des Pfeiles K in Fig. 1, kann nummehr das Arbeitsteil 2 ausweichen, indem sich das untere Ende der Haube 10 an dem Widerlager des Trägerteiles 1 abstützt, wobei gleichzeitig die Feder 6 gespannt wird und die Zugstange 3, wie in Fig. 2 dargestellt, aus ihrer in Fig. 1 dargestellten Lage in die in Fig. 2 dargestellte Lage auswandert, wobei der Neigungswinkel des Arbeitsteiles 2 abhängig ist von der auf das Arbeitsteil 2 einwirkenden Kraft K. Hier wird aber nochmals ausdrücklich darauf hingewiesen, dass die in Fig. 2 für diese Ausführungsform dargestellte Extremlage nur als Vergleich zur Erklärung des unterschiedlichen Bewegungsablaufes bei Fig. 5 dient, deren Ausführungsform - wie weiter unten beschrieben - für grosse Abwinklungen bei fester Führung geeignet ist. Die Begrenzung der Wirkweise auf die zulässige Abwinklung der Ausführungsform bei Fig. 1 und 2 wird durch die Begrenzung des Federweges erreicht.When force is exerted on the working part 2, for example in the direction of the arrow K in FIG. 1, the working part 2 can evade by the lower end of the hood 10 being supported on the abutment of the carrier part 1, the spring 6 being tensioned at the same time and the Drawbar 3, as shown in Fig. 2, migrates from its position shown in Fig. 1 in the position shown in Fig. 2, the angle of inclination of the working part 2 is dependent on the force acting on the working part 2 K. Here, however, again expressly pointed out that the extreme position shown in FIG. 2 for this embodiment only serves as a comparison for explaining the different movement sequence in FIG. 5, the embodiment of which - as described further below - is suitable for large angles with firm guidance. The limitation of the mode of action to the permissible angling of the embodiment in FIGS. 1 and 2 is achieved by limiting the spring travel.

Bei Nachlassen der Kraft K bewirkt die Feder 6 eine Rückstellung des Arbeitsteiles 2 in die Ausgangslage.When the force K decreases, the spring 6 causes the working part 2 to be returned to the starting position.

Aus der vorausgehenden Beschreibung des in den Fig. 1 und 2 dargestellten Ausführungsbeispieles ist ersichtlich, dass dann, wenn der Kegelstumpf 11 an seiner Aussenfläche mit in der Zeichnung nicht dargestellten gewindegangartigen Führungsflächen ausgerüstet ist, an denen sich die Haube 10 führt, bei Drehbewegungen des Arbeitsteiles 2 gegenüber dem ortsfest angeordneten Trägerteil 1 ein Hochschrauben des Arbeitsteiles 2 unter Spannung der Feder 6 erfolgt, so dass dann bei Nachlassen dieser Drehkraft das Arbeitsteil 2 sich wieder in die Ausgangslage zurückstellt.From the preceding description of the embodiment shown in Figs. 1 and 2 it can be seen that when the truncated cone 11 is equipped on its outer surface with thread-like guide surfaces, not shown in the drawing, on which the hood 10 is guided, during rotary movements of the working part 2 with respect to the fixedly arranged support part 1, the working part 2 is screwed up under tension of the spring 6, so that the working part 2 then returns to the starting position when this torque decreases.

Entscheidend beidererfindungsgemässen Einrichtung ist, dass die Abstützung des Arbeitsteiles 2 im Bereich des Widerlagers 9 am Trägerteil 1 derart ist, dass bei Kippbewegungen des Arbeitsteiles 2 gegenüber dem ortsfest angeordneten Trägerteil 1, der Hebelarm des Widerlagers 9 für das Arbeitsteil 2 vom Angriffspunkt der Feder am Trägerteil, d.h. also von der Anlage des Kugelendes 4 an dem Scheitel des Kegelstumpfes 11 im relevanten Bereich bei Auslenkung sogar grösser wird. Hierdurch wird sichergestellt, dass stets bei Auslenkbewegungen des Arbeitsteiles 2 gegenüber dem Trägerteil 1 das erforderliche Rückstellmoment zur Verfügung steht.It is crucial in both devices according to the invention that the support of the working part 2 in the area of the abutment 9 on the support part 1 is such that when the working part 2 is tilted relative to the fixedly arranged support part 1, the lever arm of the abutment 9 for the working part 2 from the point of application of the spring on the support part , ie that is, the contact of the ball end 4 on the apex of the truncated cone 11 in the relevant area becomes even larger when deflected. This ensures that the required restoring torque is always available when the working part 2 is deflected relative to the carrier part 1.

Fig. 3 zeigt eine abgeänderte Ausführungsform der Erfindung mit einem Trägerteil 1 a und einem Arbeitsteil 2a, wobei nunmehr die beiden Teile trogartig ineinanderfassen und damit das linienfeste Widerlager 9a im Bereich des oberen Randes des Troges des Trägerteiles 1 a gebildet wird. Hier liegt die Feder als Spiralfeder innerhalb der Haubenform. Die Halterung der Zugstange 3a erfolgt dabei verstellsicher am Trägerteil 1 a, es ist damit aber keine feste Führung des innenliegenden Bauteils an der Zugstange gegeben.Fig. 3 shows a modified embodiment of the invention with a carrier part 1 a and a working part 2a, the two parts now trough into one another and thus the linear abutment 9a is formed in the region of the upper edge of the trough of the carrier part 1 a. Here the spring is a spiral spring within the hood shape. The tie rod 3a is held securely on the support part 1 a, but there is no fixed guidance of the internal component on the tie rod.

Die Fig. 3 und 4 verdeutlichen auch, dass es für die Wirkung der erfindungsgemssen Einrichtung vollkommen unabhängig ist, ob sich die Feder 6 innerhalb des Arbeitsteiles 2 oder innerhalb des Trägerteiles 1 befindet bzw. mit anderen Worten sich innerhalb oder ausserhalb der Haubenform befindet.3 and 4 also illustrate that it is completely independent of the effect of the device according to the invention whether the spring 6 is inside the working part 2 or inside the carrier part 1 or in other words inside or outside the hood shape.

Fig. 4 soll die pyramidenartige Ausführung analog zu Kegel- bzw. Rotationsform entsprechend Fig. 1 zeigen. Auch bei dieser Ausführung sind die benannten Wirkungen der Verbindungseinrichtung gegeben.FIG. 4 is intended to show the pyramid-like design analogous to the conical or rotational shape corresponding to FIG. 1. The named effects of the connecting device are also given in this embodiment.

Fig. 5 zeigt eine wichtige Ausführungsvariante, die einen sehr grossen (ca. 90 Grad) Neigungswinkel bei fester Führung des innenliegenden Bauteils durch die Schalenkontur des äusseren Bauteils im Bewegungsablauf zulässt unter gleichzeitiger Vermeidung des für viele Konstruktionen gefährlichen Maulklaffens.Fig. 5 shows an important embodiment that allows a very large (about 90 degrees) angle of inclination with firm guidance of the inner component through the shell contour of the outer component in the motion sequence while avoiding the gaping gap that is dangerous for many constructions.

Das geschieht - anders als in Fig. 1, in der im Bewegungsablauf das sich bewegende Bauteil nur aus der Schalenform herausbewegt wird (s. Fig. 2) - mit einem Herausbewegen und einem Eintauchen des innenliegenden Bauteils, d.h. im Bewegungsablauf ist nur zu Beginn ein Herausheben wie bei Fig. 1 gegeben, danach aber folgt ein Herausheben auf der einen Seite mit dem gleichzeitigen Wiedereintauchen auf der anderen Seite.This happens - unlike in Fig. 1, in which the moving component is only moved out of the shell shape in the course of movement (see Fig. 2) - with moving out and immersing the internal component, i.e. in the course of movement there is only a lifting out at the beginning as in FIG. 1, but then a lifting out follows on one side with simultaneous immersion on the other side.

Schliesslich zeigt die Fig. 6 die Ausführung als Profilabschnitt, analog zur kegelförmigen Ausführung der Fig. 1 mit flächiger Anlage und analog zur Ausführungsform Fig. 3 als Profilabschnittausführung. In diesem Beispiel dient das eigentliche Arbeitsteil als Schilderträger. Die für die Erfindung benannten Wirkungen werden auch hier erreicht, d.h. auch diese Form kann nicht nur die Kippkräfte in Drehmomente umwandeln, sondern auch Drehkräfte aufnehmen und eine räumliche (XYZ) Reorientierung nach Beendigung der Störkraft wiederherstellen.Finally, FIG. 6 shows the design as a profile section, analogous to the conical design of FIG. 1 with a flat contact and analogous to the embodiment of FIG. 3 as a profile section design. The actual work part is used in this example as a label holder. The effects named for the invention are also achieved here, ie this form can not only convert the tilting forces into torques, but can also absorb torsional forces and restore spatial (XYZ) reorientation after the interference force has ended.

Claims (11)

1. Connection device for two antagonistically movable members (A, B), wherein a fixed base part (1, 1 a, 1b) is supported, via mutually supporting bearing elements and an interposed tension bar (3) which connects the members and is disposed at the centre of the members and of the spring (6), against a working part (2, 2a, 2b) which can be swivelled relative to said base part against the restoring force of a spring, and wherein in the course of deflection the lever arm present between the fulcrum point and the line of action of the spring is greater than zero, so that the force of the spring is simultaneously used to generate the restoring torque, characterised in that
a) one of the members (A or B) has a U-shaped cross-section with diverging legs and the other member (B or A) has the form of a cap component overlapping the diverging legs from the web,
b) the point of application of force of the tension bar on one member (A or B) - in the direction in which the force of the spring acts - is remote from the plane of the bearing and
c) that within the free inner space formed by the spring (6) perpendicular to the longitudinal axis of the tension bar (3), said tension bar (3) can move in its undeflected position, one end of the tension bar being able to maintain the position on the undeflected longitudinal axis.
2. Device acording to Claim 1, characterised in that the spring (6) is accomodated inside the working part (2) (Figs. 1 and 6).
3. Device according to Claim 1, characterised in that the spring (6) is accomodated inside the base part (1) (Fig. 5).
4. Device according to Claim 1, characterised in that the tension bar (3) is movably linked to the base part (1) (Figs. 1, 2 and 5).
5. Device according to Claim 1, characterised in that the tension bar (3a) is fixedly linked to the base part (1a) (Fig. 3).
6. Device according to one or more of the preceding claims, characterised in that one of the members (A or B) is constructed as a rotationally symmetric, bell-shaped truncated cone (11) and the other member as a cap (10) overlapping the bell-shaped truncated cone (11 the contours in the cutaway view being formed by the radius drawn about the abutment.
7. Device according to one or more of the preceding claims, characterised in that the member (A) constructed as a bell-shaped truncated cone is provided on its outer face with thread-type guide faces and the overlapping member (B) is provided in section with centring faces (circle with secants), in order to convert not only rocking motions but also slewing motions of one member relative to the other by altering the distance of one member from the other while the tension of the spring (6) increases.
8. Device according to one or more of the preceding claims, characterised in that in section the contour of the bell-shaped truncated cone does not follow the radius right to the end, but changes to a tangent, the shape of which in both members is not rotationally symmetric but contains plane faces.
9. Device according to one or more of the preceding claims, characterised in that the two cooperating parts (A, B) respond to torsional strains with a restoring movement.
10. Device according to Claim 9, characterised in that two countercurrent threaded sleeves which are arrested in the direction of rotation are accomodated in the shaft of the working part and are adapted to convert large slewing movements of one member relative to the other, i.e. exceeding 45 °, into increasing tension of the spring.
11. Device according to one or more of Claims 1 to 10, characterised in that the externally induced, repeated change of position of the working part to the base part is used to control an electric contact which in turn indicates or terminates other functions.
