Definitions
- the hinge pin according to the invention further comprises at least two bearing pieces, which alone or predominantly serve the initiation of mechanical forces in the hinge pin or the exercise of mechanical forces by the hinge pin, so ultimately the transmission of mechanical forces between the wing and the wall.
- the middle piece also has counter-centering surfaces for a respective centering surface of a flow element.
- the center piece is also made of a low permeability material to reduce unwanted magnetic coupling of the two flux elements.
- the hinge pin 3, 103 connects hinge parts 14, 15, 16 pivotally about a hinge axis S.
- the device 100 is constructed similar to a three-part belt. It may be arranged in addition to the load of the wing receiving bands of known design between the wing and frame or instead of such a band. The device 100 can therefore also absorb mechanical forces, in particular forces to be transmitted between the wall and the wing.
- the hinge pin 3, 103 is formed in several parts. It comprises two spaced-apart flow elements 4, 4 '; 104, 104 ', which are spaced from each other by a central piece 7, 107.
- the flow elements 4, 4 '; 104, 104 ' are dimensioned to match that of the coils 1, 2; 9, 10 enclosed space substantially completely fill, but not protrude from them.
- the hinge pin 3, 103 is - as below with reference to the Fig. 2 to 13 is explained in more detail - constructed entirely of individual parts.
- the flow elements 4, 4 '; 104, 104 ' are made of soft magnetic material, such as ferrite.
- the Center piece 7, 107 is for magnetic decoupling of the flow elements 4, 4 '; 104, 104 ', as well as the bearing pieces 8, 8'; 108, 108 'made of a material having a low permeability.
- the center piece 7, 107 made of a damping material, for example made of plastic.
- a constriction 13 for fixing in the direction of the hinge axis S, it has a constriction 13, in which engages a stud bolt, not shown in the drawing.
- the internal threads 6 can be designed to be self-tapping, so that only cylinder bores must be provided in the bearing pieces 8, 8 ' 6 is formed of a material suitable for receiving high tensile stresses, such as an iron alloy.
- the diameter of the tension member may be relatively small, for example, less than half the diameter of the hinge pin.
- the diameter of the tension member is slightly larger than one third of the diameter of the hinge pin 3. Due to the relatively small diameter, the flow elements 4, 4 'occupy a relatively large cross-sectional area. This results in a particularly low magnetic resistance and the highest possible inherent stability of the flow elements 4, 4 '.
- the hinge pin 3 is easy to assemble in the manufacture and also for the processor who inserts it into the device 100. There are no ferritic half-shells and no often critical bonds.
- the hinge pin is simple and has an automatic tolerance compensation in the assembly length by the elastic properties of the center piece 7 and the tension element 6. It is always centered by the self-centering components and therefore easily mounted on the belt or the device. It is very easy to adapt to other dimensional and coil situations (modular system).
- Fig. 7 to 12 show a designated as a whole with 103, second embodiment of a hinge pin, which is used as an alternative to the first embodiment 3.
- Functionally equivalent components of the second embodiment are designated by the same reference numerals, but increased by 100.
- the hinge pin 103 has no tension element. Rather, two flow elements 104, 104 'are provided, which each have threaded extensions 104a, 104a' at their two front ends. These thread extensions 3 engage in complementary threaded bores 105, 105 'which are provided in the bearing pieces 108, 108' and the center piece 107 ( Fig. 9 ).
- the bearing pieces 108, 108 ' have key surfaces 108a, 108a'.
- All parts 104, 104 ', 105, 107, 108, 108' of the hinge pin 103 are screwed together. Also in this embodiment, chamfers 111, 112 are provided, which cause a self-centering of the components when screwing together.
- threaded extensions can also be realized on the bearing and center pieces and, accordingly, the complementary threaded holes in the flow elements.
Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur kontaktlosen Übertragung von elektrischer Energie zwischen einer Wand und einem an dieser Wand um eine Scharnierachse scharniergelenkig befestigten Flügel, bei dem eine an der Wand befestigte Primärspule und eine an dem Flügel befestigte Sekundärspule vorgesehen sind, die sich mit Hilfe eines Bandbolzens in induktiver Wirkverbindung befinden.The invention relates to a device for the contactless transmission of electrical energy between a wall and a hinge hingedly mounted on this wall about a hinge axis in which a fixed to the wall primary coil and a secondary wing attached to the wing are provided by a hinge pin are in inductive active connection.
Insbesondere Flügel von Türen für Objekte wie Häuser, Geschäfte oder Produktionshallen weisen in zunehmendem Maße die Sicherheit oder den Komfort verbessernde Einrichtungen auf, deren jeweils aktueller Betriebszustand und deren Betätigung durch außerhalb der Tür angeordnete Überwachungs- oder Betätigungseinrichtungen überwacht oder betätigt wird und welche Betriebszustandsänderungen oder eventuell von Sensoren empfangene Signale an die Überwachungs- oder Betätigungseinrichtungen senden.In particular, wings of doors for objects such as houses, shops or production halls increasingly have the safety or comfort improving facilities, the current state of operation and their operation is monitored or operated by located outside the door monitoring or actuation devices and which operating state changes or possibly send signals received from sensors to the monitoring or actuation devices.
Beispielhaft sei hier eine in dem Gebäude installierte Gefahrenmeldeanlage genannt, die mit an der Tür vorgesehenen Einrichtungen beispielsweise zur Öffnungs-, Durchbruch-, Verschluss-, Sabotage-, oder Motorschlossüberwachung kommuniziert.As an example, a warning system installed in the building may be mentioned, which communicates with devices provided on the door, for example for opening, breakthrough, closure, sabotage or engine lock monitoring.
Zur Übertragung von entsprechenden Signalen und elektrischen Leistungen zwischen der Überwachungseinrichtung und an den an der Tür befindlichen Einrichtungen finden im Stand der Technik vielartige Kabel Verwendung, die zwischen dem Flügel und dem Rahmen flexibel verlegt und häufig zum Schutz von einem flexiblen Metallschlauch umgeben sind.To transmit corresponding signals and electrical power between the monitoring device and the devices located on the door, many types of cables are used in the art that are flexibly routed between the sash and the frame and are often surrounded by a flexible metal hose for protection.
Diese Kabelübergänge beeinträchtigen das optische Erscheinungsbild erheblich und können beim Schließen des Flügels eingeklemmt werden, was zu Beschädigungen oder sogar zur Zerstörung der Kabel führen kann. Darüber hinaus stellen die Kabelübergänge hinsichtlich möglicher Manipulationen Schwachstellen dar, weswegen zum Sabotageschutz eine sogenannte Z-Verdrahtung von Sensoren oder Kontakten auch in dem Kabelübergang verwirklicht ist.These cable transitions affect the visual appearance significantly and can be trapped when closing the wing, which can lead to damage or even the destruction of the cable. In addition, the cable transitions are weak points with regard to possible manipulations, which is why so-called Z-wiring of sensors or contacts is also realized in the cable transition for sabotage protection.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung mit einem hinsichtlich der induktiven Wirkverbindung der Primär- und der Sekundärspulen verbesserten Bandbolzen zu schaffen.The invention has for its object to provide a generic device with a respect to the inductive operative connection of the primary and secondary coils improved hinge pin.
Diese Aufgabe wird durch die in Anspruch 1 wiedergegebene Erfindung gelöst.This object is achieved by the reproduced in
Der Bandbolzen der erfindungsgemäßen Vorrichtung ist mehrteilig ausgebildet. Er umfasst mindestens zwei als vorgefertigte Bauteile ausgestaltete Flusselemente. Hiermit ist das Bauteil gemeint, welches allein oder in überwiegendem Maße den magnetischen Fluss zwischen der Primärspule und der Sekundärspule leitet. Diese Flusselemente sind vorgefertigt. Hiermit ist gemeint, dass es nicht erst gegossen, gespritzt oder auf sonstige Art an ein anderes, bestehendes Bauteil des Bandbolzens angeformt werden muss. Es liegt vielmehr vor dem Zusammenfügen mit zumindest einem weiteren Teil des Bandbolzens zumindest in nahezu seiner endgültigen Form vor.The hinge pin of the device according to the invention is designed in several parts. It comprises at least two flow elements designed as prefabricated components. By this is meant the component which alone or predominantly conducts the magnetic flux between the primary coil and the secondary coil. These flow elements are prefabricated. By this is meant that it does not first cast, sprayed or otherwise formed on another, existing component of the hinge pin. Rather, it is at least almost in its final form prior to assembly with at least one other part of the hinge pin.
Der erfindungsgemäße Bandbolzen umfasst darüber hinaus mindestens zwei Lagerstücke, welche allein oder in überwiegendem Maße der Einleitung von mechanischen Kräften in den Bandbolzen bzw. der Ausübung von mechanischen Kräften durch den Bandbolzen, also letztlich der Übertragung von mechanischen Kräften zwischen dem Flügel und der Wand dienen.The hinge pin according to the invention further comprises at least two bearing pieces, which alone or predominantly serve the initiation of mechanical forces in the hinge pin or the exercise of mechanical forces by the hinge pin, so ultimately the transmission of mechanical forces between the wing and the wall.
Durch den mehrteiligen Aufbau können die Flusselemente und die Lagerstücke auf verschiedene Eigenschaften, wie geringen magnetischen Widerstand im Falle des Flusselements oder hohe mechanische Belastbarkeit im Falle des Lagerstücks optimiert und dort angeordnet werden, wo diese Eigenschaften in besonderem Maße erforderlich sind. Das vorgefertigte Flusselement kann aus einem für den jeweiligen Anwendungszweck der Vorrichtung besonders geeignetem Material gefertigt sein. Soll beispielsweise die Vorrichtung zur Übertragung einer Wechselspannung von etwa 50 Hz dienen, so kann das Flusselement beispielsweise aus Dynamoblech bestehen oder solches umfassen. Weist die Wechselspannung eine höhere Frequenz auf, beispielsweise im Kilohertzbereich, so kann das Flusselement beispielsweise aus amorphen oder nanokristallinen Bändern oder auch aus Ferriten bestehen oder solche umfassen.Due to the multi-part structure, the flow elements and the bearing pieces can be optimized for various properties, such as low magnetic resistance in the case of the flow element or high mechanical strength in the case of the bearing piece and placed where these properties are particularly required. The prefabricated flow element can be made of a material which is particularly suitable for the particular application of the device. If, for example, the device is intended to transmit an alternating voltage of approximately 50 Hz, then the flux element can consist of or include, for example, dynamo plate. Does the AC voltage have one higher frequency, for example in the kilohertz range, the flux element may for example consist of or comprise amorphous or nanocrystalline ribbons or also of ferrites.
Da die Fertigung der Flusselemente separat von den weiteren Teilen des Bandbolzens erfolgt, ist sie besonders einfach und preisgünstig. Auch können für unterschiedliche Anwendungszwecke optimierte Flusselemente zusammen mit den weiteren Bauteilen des Bandbolzens in einer Art Baukastensystem vorgehalten werden.Since the production of the flow elements is done separately from the other parts of the hinge pin, it is particularly simple and inexpensive. Also optimized for different purposes flow elements can be kept together with the other components of the hinge pin in a kind of modular system.
Die Flusselemente umfassen Stirnseiten, von denen zumindest eine gegen eine Gegenstirnseite eines Lagerstücks verspannt ist. Hierdurch sind das Lagerstück und das Flusselement zuverlässig zueinander fixiert.The flow elements comprise end faces, of which at least one is clamped against a counter-end face of a bearing piece. As a result, the bearing piece and the flow element are reliably fixed to each other.
Das Flusselement ist bevorzugt rotationssymmetrisch. Hierdurch kann es zugunsten eines besonders geringen magnetischen Widerstands eine größtmögliche Querschnittsfläche aufweisen. Zudem sind störende, axial auf der Oberfläche des Bandbolzens verlaufende Kanten des Flusselements, wie sie etwa bei einem aus Halbschalen gebildeten Flusselement denkbar sind, ausgeschlossen.The flow element is preferably rotationally symmetrical. As a result, it can have the greatest possible cross-sectional area in favor of a particularly low magnetic resistance. In addition, disturbing, axially on the surface of the hinge pin extending edges of the flow element, as are conceivable, for example, in a flow element formed from half-shells excluded.
Zum Bewirken der Verspannung ist bei einer ersten, bevorzugten Variante des Bandbolzens mindestens ein die Flusselemente in einer zentralen Bohrung durchsetzendes Zugelement vorgesehen, das mit mindestens einem Lagerstück verbunden ist. Dabei werden der Durchmesser des Zugelements und der Bohrung des Flusselements möglichst klein gehalten, damit das Flusselement die maximal mögliche Querschnittsfläche zur Minimierung des magnetischen Widerstands aufweist. Für das Zugelement findet daher vorzugsweise ein Werkstoff Verwendung, welcher eine zur Erzielung der für den jeweiligen Anwendungsfall erforderlichen Stärke der Verspannung ausreichende Zugfestigkeit aufweist.In order to effect the bracing, in a first, preferred variant of the hinge pin, at least one tension element passing through the flow elements in a central bore is provided, which is connected to at least one bearing piece. In this case, the diameter of the tension element and the bore of the flow element are kept as small as possible, so that the flow element has the maximum possible cross-sectional area for minimizing the magnetic resistance. Therefore, preferably a material is used for the tension element, which has a sufficient tensile strength to achieve the required for the particular application strength of the strain.
Das Zugelement ist vorzugsweise mit mindestens einem Lagerstück verschraubt, da diese Verbindung maschinentechnisch einfach realisierbar und lösbar ist. Zudem kann eine gewünschte Zugspannung durch Festlegung des Drehmoments, mit welcher die Verschraubung erfolgt, erzielt werden.The tension element is preferably screwed to at least one bearing piece, since this connection is easily realized in terms of machine technology and can be solved. In addition, a desired tensile stress can be achieved by fixing the torque with which the screw connection takes place.
Die erfindungsgemäße Vorrichtung umfasst zwei voneinander beabstandete Spulenpaare, bestehend jeweils aus einer Primär- und einer Sekundärspule. Dies beispielsweise dann, wenn ein Spulenpaar der Übertragung elektrischer Leistung, das andere Spulenpaar der Übertragung elektrischer Signale zwischen Band und Flügel dienen soll. Der erfindungsgemäße Bandbolzen umfasst zwei voneinander durch ein Mittelstück, welches voneinander fort weisende Gegenstirnseiten umfasst, voneinander beabstandete Flusselemente. Die Flusselemente können durch unterschiedliche Dimensionierung und Materialwahl an die mit Hilfe des jeweiligen Spulenpaars zu übertragende Leistung, Frequenz, Signalform etc. angepasst sein.The device according to the invention comprises two spaced coil pairs, each consisting of a primary and a secondary coil. This, for example, when a pair of coils of the transmission of electrical power, the other pair of coils to serve the transmission of electrical signals between the band and wing. The hinge pin according to the invention comprises two flow elements spaced apart from one another by a central piece, which comprises mutually facing opposite end faces. The flow elements can be adapted to the power, frequency, signal shape etc. to be transmitted by means of the respective coil pair by means of different dimensioning and choice of material.
Um beispielsweise die Übertragung von Stößen oder Schwingungen von dem einen Flusselement auf das andere Flusselement zu reduzieren, kann das Mittelstück so ausgebildet sein, dass es dämpfende Eigenschaften aufweist. Hierzu kann es beispielsweise aus einem dämpfende Eigenschaften aufweisenden Material, beispielsweise einem geeigneten Kunststoffmaterial, ausgebildet sein.For example, to reduce the transmission of shock or vibration from one flow element to the other flow element, the center piece may be formed to have damping properties. For this purpose, it may be formed, for example, from a material having damping properties, for example a suitable plastic material.
Das Mittelstück weist vorzugsweise eine Durchgangsbohrung auf, die von dem Zugelement durchsetzt wird, welches mit Lagerstücken verschraubt ist, die Endstücke, d.h. die beiden Endbereiche des Bandbolzens bilden, denen im wesentlichen die Lagerfunktion zukommt und die der Übertragung mechanischer Kräfte dienen.The middle piece preferably has a through-hole penetrated by the pulling element which is screwed to bearing pieces, the end pieces, i. form the two end portions of the hinge pin, which essentially plays the bearing function and which serve to transmit mechanical forces.
Bei einem zweiten Ausführungsbeispiel der erfindungsgemäßen Vorrichtung ist an mindestens einem Flusselement stirnseitig ein Gewindefortsatz oder eine Gewindebohrung und an der zugewandten Gegenstirnseite des Lagerstücks eine komplementäre Gewindebohrung oder ein Gewindefortsatz vorgesehen, so dass das mindestens eine Flusselement mit dem Lagerstück verschraubbar ist. Dieses Ausführungsbeispiel unterscheidet sich von dem oben beschriebenen, ersten Ausführungsbeispiel somit darin, dass kein separates Zugelement vorhanden ist, sondern die Verspannung der Stirn- und Gegenstirnseiten gegeneinander, durch ein Eindrehen des Gewindefortsatzes in die Gewindebohrung erzeugt wird. Die Stärke der Verspannung bzw. der Wert der Druckkraft, mit welcher die Stirn- und Gegenstirnseiten aufeinander liegen, kann wiederum durch die Vorgabe des Drehmoments, mit welchem der Eindrehvorgang erfolgt, bestimmt werden.In a second embodiment of the device according to the invention, a threaded extension or a threaded bore is provided on at least one flow element and a complementary threaded bore or threaded extension on the facing counter-end side of the bearing piece, so that the at least one flow element can be screwed to the bearing piece. This embodiment differs from the first embodiment described above, thus, in that no separate tension element is present, but the tension of the front and opposite ends against each other, is produced by a screwing of the thread extension in the threaded bore. The strength of the tension or the value of the compressive force with which the forehead and counter-faces are superimposed, in turn, by specifying the torque with which the screwing takes place, be determined.
Da der Bandbolzen für eine Vorrichtung mit zwei Spulenpaaren geeignet ist, umfasst er die zwei voneinander durch ein Mittelstück voneinander beabstandeten Flusselemente. Das Mittelstück weist voneinander fort weisende Gegenstirnseiten auf, wobei an den Gegenstirnseiten zu den Gewindefortsätzen oder Gewindebohrungen der Flusselemente komplementäre Gewindebohrungen oder Gewindefortsätze vorgesehen sind, so dass die Flusselemente mit dem Mittelstück verschraubbar sind. Das Mittelstück kann wiederum derart ausgebildet sein, dass es dämpfende Eigenschaften aufweist.Since the hinge pin is suitable for a two coil pair device, it comprises the two flux elements spaced apart from each other by a central piece. The middle piece has opposing end faces pointing away from one another, wherein complementary threaded bores or thread extensions are provided at the opposite end faces to the thread extensions or threaded bores of the flow elements, so that the flow elements can be screwed to the center piece. The center piece may in turn be designed such that it has damping properties.
Bei beiden Ausführungsformen ist es vorteilhaft, wenn die Lagerstücke eine Zentrierfläche und die Flusselement eine Gegenzentrierfläche aufweisen, so dass Lagerstück und Flusselement im Rahmen zulässiger Toleranzen zuverlässig zueinander positioniert sind, ohne dass es hierzu über das bloße Zusammenfügen hinausgehender Maßnahmen bedarf.In both embodiments, it is advantageous if the bearing pieces have a centering surface and the flow element has a counter-centering surface, so that the bearing piece and flow element are reliably positioned within permissible tolerances with respect to one another, without the need for additional measures beyond mere joining.
Vorzugsweise weist auch das Mittelstück Gegenzentrierflächen für jeweils eine Zentrierfläche eines Flusselements auf.Preferably, the middle piece also has counter-centering surfaces for a respective centering surface of a flow element.
Um zu vermeiden, dass die induktive Ankopplung von Primär- und Sekundärspule durch unnötige Streuverluste beeinträchtigt wird, bestehen die Lagerstücke besonders bevorzugt aus einem Material mit geringer Permeabilität. Auch wird aufgrund dieser Maßnahme die Störanfälligkeit gegen äußere Magnetfelder, die möglicherweise auf die Lagerstücke wirken, reduziert.In order to avoid that the inductive coupling of primary and secondary coil is affected by unnecessary leakage losses, the bearing pieces are particularly preferably made of a material with low permeability. Also, due to this measure, the susceptibility to external magnetic fields, which may act on the bearing pieces, reduced.
Vorzugsweise ist auch das Mittelstück aus einem Material mit geringer Permeabilität gefertigt um ein unerwünschtes magnetisches Ankoppeln der beiden Flusselemente zu reduzieren.Preferably, the center piece is also made of a low permeability material to reduce unwanted magnetic coupling of the two flux elements.
Die Erfindung bezieht sich auch auf einen Bandbolzen für sich genommen einer Vorrichtung nach der vorbeschriebenen Art. Bei den für die einzelnen Teile verwendeten Materialien handelt es sich vorzugsweise nicht um aus verschiedenen Materialien zusammengesetzte Bauteilen, wie etwa einen mit hochpermeablem Material umspritzten Metallkern. Sondern jedes Teil besteht vorzugsweise aus einem einzigen handelsüblichen Material oder aus einer einzigen handelsüblichen Materialkombination.The invention also relates to a hinge pin taken by itself a device of the type described above. In the used for the individual parts Materials are preferably not components composed of different materials, such as a metal core overmolded with high permeability material. But each part is preferably made of a single commercially available material or a single commercial material combination.

Der Bandbolzen 3, 103 verbindet Bandteile 14, 15, 16 schwenkbar um eine Scharnierachse S. Die Vorrichtung 100 ist ähnlich einem dreiteiligen Band aufgebaut. Sie kann zusätzlich zu die Last des Flügels aufnehmenden Bändern bekannter Bauart zwischen Flügel und Rahmen angeordnet sein oder anstelle eines solchen Bandes. Die Vorrichtung 100 kann demnach auch mechanische Kräfte, insbesondere zwischen Wand und Flügel zu übertragende Kräfte aufnehmen.The

Um dem Bandbolzen 3, 103 dämpfende Eigenschaften zu verleihen, die die Übertragung beispielsweise von Vibrationen zwischen den Flusselementen 4, 4'; 104, 104' zumindest reduziert, kann das Mittelstück 7, 107 aus einem dämpfenden Material, beispielsweise aus Kunststoff bestehen.

Der Bandbolzen 3 ist bei der Herstellung und auch für den Verarbeiter, der ihn in die Vorrichtung 100 einsetzt, leicht zu montieren. Es sind keine ferritischen Halbschalen und auch keine oft kritischen Verklebungen vorhanden. Der Bandbolzen ist einfach aufgebaut und weist einen automatischen Toleranzausgleich in der Baugruppenlänge durch die elastischen Eigenschaften des Mittelstücks 7 und des Zugelements 6 auf. Er ist durch die selbstzentrierenden Bauteile stets zentrisch montiert und daher leicht am Band bzw. der Vorrichtung montierbar. Er ist sehr leicht an weitere Maß- und Spulensituationen anpassbar (Baukastensystem).The
Durch den geringen magnetischen Widerstand der Flusselemente 4, 4' ist die induktive Ankopplung optimiert. Durch die stoßdämpfende Wirkung des Mittelstücks 7, welches ein Kunststoffteil umfassen kann, wird die unerwünschte Schwingungs- oder Stoßübertragung zwischen den Flusselementen 4, 4' reduziert und die Zähigkeit des Bandbolzens 3 verbessert. Der geringe Durchmesser des Zugelements erlaubt einen effektiven Einsatz des die stoßdämpfende Wirkung aufweisenden Mittelteils. Durch die Verschraubung des Zugelements 6 mit den Lagerstücken 8, 8' ist der Aufbau des Bandbolzens 3 flexibel, da sowohl die Flusselemente 4, 4', als auch das Mittelstück 7 leicht austauschbar sind.Due to the low magnetic resistance of the

Im Unterschied zu dem ersten Ausführungsbeispiel weist der Bandbolzen 103 kein Zugelement auf. Vielmehr sind zwei Flusselemente 104, 104' vorgesehen, die an ihren beiden Stirnenden jeweils Gewindefortsätze 104a, 104a' aufweisen. Diese Gewindefortsätze 3 greifen in komplementäre Gewindebohrungen 105, 105' ein, die in den Lagerstücken 108, 108' und dem Mittelstück 107 vorgesehen sind (
Alle Teile 104, 104', 105, 107, 108, 108' des Bandbolzens 103 sind miteinander verschraubt. Auch bei diesem Ausführungsbeispiel sind Fasen 111, 112 vorgesehen, die eine Selbstzentrierung der Bauteile beim Zusammenschrauben bewirken.All
Es versteht sich, dass alternativ die Gewindefortsätze auch an den Lager- und Mittelstücken und dementsprechend die komplementären Gewindebohrungen in den Flusselementen verwirklicht sein können.It is understood that alternatively the threaded extensions can also be realized on the bearing and center pieces and, accordingly, the complementary threaded holes in the flow elements.
Im zusammengefügten Zustand der erfindungsgemäßen Vorrichtung definiert der Bandbolzen die Scharnierachse S, d.h. seine Längsmittelachse A und die Scharnierachse S fallen zusammen.In the assembled state of the device according to the invention the hinge pin defines the hinge axis S, ie its longitudinal central axis A and the hinge axis S coincide.
