Auf diese Weise kann eine Parallel-Ausstellvorrichtung bereitgestellt werden, welche wenig Platz beansprucht, insbesondere in einem zusammengeschobenen bzw. eingeklappten Zustand bei geschlossenem Fenster. Es wird in einer x-Richtung nur die Breite der Führung als Platz beansprucht. Daher kann auch eine Verwendung bei sehr schmalen Fensterflügeln (oder Klappen, Abzügen, Kaminen oder dergleichen) erfolgen, selbst dann wenn der Flügel sehr weit ausgestellt werden soll. Denn durch die vier Scherenarme kann eine größere Distanz überbrückt werden.Preferably, the scissor arms each have a gradation and a recess and are constructed identically and arranged to each other so that the recesses of a respective Scherenarmpaar the scissor arms point to each other and the gradations are opposite. In this way, a parallel-opening device can be provided, which takes up little space, especially in a collapsed or folded state with the window closed. It is claimed in an x-direction only the width of the guide as a place. Therefore, even with very narrow window sashes (or flaps, fume hoods, chimneys or the like) can be used, even if the wing is to be issued very far. Because of the four scissor arms a larger distance can be bridged.
Weiter bevorzugt sind auch die Führungen identisch aufgebaut. Besonders bevorzugt sind die Scherenarme, die Führungen und auch die an den Führungen angeordneten Drehlagerungen jeweils identisch aufgebaut. Dies erleichtert die Montage, auch für Endverbraucher, und kann zu einer sehr kostengünstigen Ausstellvorrichtung führen.More preferably, the guides are constructed identically. Particularly preferably, the scissor arms, the guides and also arranged on the guides pivot bearings are each constructed identically. This facilitates assembly, even for end users, and can lead to a very cost-effective Ausstellvorrichtung.
Gemäß einem weiteren Ausführungsbeispiel sind die freien endseitigen Scherengelenke sowie die an den Führungen vorgesehenen Drehlagerungen so angeordnet, dass sie mit einer Oberfläche der jeweiligen Scherenarme in einer Ebene abschließen oder unterhalb der Oberfläche abschließen. Hierdurch können alle Scherenarme direkt übereinander bzw. aufeinander zur Anlage gebracht werden, ohne dass sie in einem Abstand zueinander angeordnet sein müssen. Dies liefert eine sehr kompakte Anordnung mit wenig Platzbedarf. Insbesondere können die Scherenarme so eng aneinander anliegen, dass alle vier Scherenarme nur einen Platzbedarf von der vierfachen Dicke eines der Scherenarme erfordern. Der Platzbedarf ist allenfalls um einige Prozent größer, z.B. um weniger Reibung zwischen den Scherenarmen zu haben, oder um einen besonders leichtgängigen Mechanismus bereitzustellen. Der Platzbedarf ist dabei nur noch von der Dicke der Scherenarme abhängig, und so kann durch die Wahl eines belastbaren Werkstoffs eine äußerst kompakte Parallel-Ausstellvorrichtung bereitgestellt werden.According to a further embodiment, the free end-side scissor hinges and provided on the guides pivot bearings are arranged so that they conclude with a surface of the respective scissor arms in a plane or terminate below the surface. As a result, all scissor arms can be brought directly to one another or to each other to the plant, without having to be arranged at a distance to each other. This provides a very compact arrangement with little space. In particular, the scissor arms can lie so close to each other that all four scissor arms only a space requirement of four times the thickness of one of Require scissor arms. The space requirement is possibly greater by a few percent, for example in order to have less friction between the scissor arms, or to provide a particularly smooth mechanism. The space requirement is dependent only on the thickness of the scissor arms, and thus can be provided by the choice of a resilient material an extremely compact parallel-opening device.
Gemäß einem weitern Ausführungsbeispiel sind die Scherenarme als ein erster äußerer Scherenarm unter einem ersten mittleren Scherenarm unter einem zweiten mittleren Scherenarm unter einem zweiten äußeren Scherenarm zueinander angeordnet und so gelagert, dass die beiden mittleren Scherenarme in einem ersten freien endseitigen Scherengelenk und die beiden äußeren Scherenarme in einem zweiten freien endseitigen Scherengelenk jeweils an freien Enden miteinander gekoppelt sind. Bevorzugt sind dabei die Abstufungen bei den axial verschiebbaren Drehlagerungen sowie bei einem der freien endseitigen Scherengelenke angeordnet.According to a further embodiment, the scissor arms are arranged as a first outer scissor arm under a first middle scissor arm under a second middle scissor arm under a second outer scissor arm to each other and stored so that the two middle scissor arms in a first free end scissors hinge and the two outer scissor arms in a second free end scissors joint are each coupled together at free ends. The gradations are preferably arranged in the axially displaceable pivot bearings and in one of the free end-side scissor hinges.
Hierdurch können die Scherenarme alle an demselben freien Ende einander hintergreifen, und eine einfache Vorrichtung mit einfach aufgebauten Scherenarmen kann bereitgestellt werden. Gleichzeitig wird eine symmetrische Vorrichtung bereitgestellt, welche die Montage erleichtert und auch eine gleichlaufende Mechanik gewährleistet. Die Symmetrie ist dabei nicht nur bezüglich einer durch die freien endseitigen Scherengelenke verlaufenden und parallel zu der yz-Ebene angeordneten Symmetrieebene gegeben, sondern kann auch bezüglich einer durch die freien endseitigen Scherengelenke verlaufenden und parallel zu der xy-Ebene angeordneten Symmetrieebene gegeben sein. Mit anderen Worten ist das zweite Scherenarmpaar so wie das erste Scherenarmpaar angeordnet bzw. gelagert. Dadurch können sich die Scherenarme gut gegenseitig stabilisieren. Ferner kann eine besonders kompakte Anordnung der Scherenarme im zusammengeschobenen Zustand bereitgestellt werden.This allows the scissor arms to all engage behind each other at the same free end, and a simple device with simple scissor arms can be provided. At the same time a symmetrical device is provided which facilitates the assembly and also ensures a synchronous mechanism. The symmetry is not only given with respect to a plane of symmetry running through the free end-side scissor hinges and arranged parallel to the yz plane, but may also be given with respect to a plane of symmetry running through the free end-side scissor joints and arranged parallel to the xy plane. In other words, the second pair of scissor arms is arranged or mounted like the first pair of scissor arms. This allows the scissor arms to stabilize each other well. Furthermore, a particularly compact arrangement of the scissor arms can be provided in the collapsed state.
Gemäß einem weiteren Ausführungsbeispiel sind die Ausnehmungen rechteckig ausgebildet. Hierdurch können die Ausnehmungen auf einfache Weise in die Scherenarme eingebracht werden, ohne dass Spezialwerkzeug einer bestimmten Geometrie erforderlich ist. Je nach Material der Scherenarme kann die Ausnehmung z.B. mit einem Nutenfräser oder einem feilenartigen Werkzeug eingebracht werden.According to a further embodiment, the recesses are rectangular. As a result, the recesses can be easily introduced into the scissor arms, without special tool a certain geometry is required. Depending on the material of the scissor arms, the recess can be introduced, for example, with a slot cutter or a file-like tool.
Gemäß einem weiteren Ausführungsbeispiel sind die Abstufungen orthogonal zu einer jeweiligen Erstreckungsrichtung der Scherenarme vorgesehen und in einem Randbereich der Ausnehmungen angeordnet. Dadurch können die Scherenarme sich beim Hintergreifen gegenseitig stabilisieren, insbesondere da ein Rand der Ausnehmung des einen Scherenarms an der Abstufung des anderen Scherenarms zu Anlage kommen kann. Bevorzugt überlappt die Ausnehmung die Abstufung um mindestens die Dicke des Scherenarms. Hierdurch kann jeder Scherenarm identisch ausgeführt sein, und ein Hintergreifen kann auf einfache Weise erfolgen, insbesondere indem zwei Scherenarme eines Scherenarmpaares mit ihren jeweiligen Vorderseiten bzw. Rückseiten aufeinanderliegend miteinander gekoppelt werden.According to a further embodiment, the gradations are provided orthogonal to a respective extension direction of the scissor arms and arranged in an edge region of the recesses. This allows the scissor arms stabilize each other when engaging behind, especially as one edge of the recess of a scissor arm can come to rest on the gradation of the other scissor arm. Preferably, the recess overlaps the gradation by at least the thickness of the scissor arm. In this way, each scissor arm can be made identical, and a gripping behind can be done in a simple manner, in particular by two scissor arms of a pair of scissor arms with their respective front sides and back sides are coupled to each other.
Gemäß einem weiteren Ausführungsbeispiel sind die Abstufungen und die Ausnehmungen bei den axial verschiebbaren Drehlagerungen sowie bei einem zweiten mit den Drehlagerungen fluchtenden freien endseitigen Scherengelenk angeordnet. Hierdurch kann das Hintergreifen einheitlich auf einer Seite der Parallel-Ausstellvorrichtung erfolgen, und es kann effektiver vermieden werden, dass sich die Scherenarme gegenseitig verkanten oder beim Hinterschneiden aneinanderstoßen.According to a further embodiment, the gradations and the recesses in the axially displaceable pivot bearings and at a second aligned with the rotary bearings free end scissors hinge are arranged. In this way, the engaging behind can be uniform on one side of the parallel-Ausstellvorrichtung, and it can be effectively avoided that the scissor arms tilt each other or abut each other when undercutting.
Als mit den Dreh-Gleitlagerungen fluchtend ist ein Scherengelenk aufzufassen, welches in einer x-Richtung gesehen auf einer virtuellen Achse mit den Dreh-Gleitlagerungen angeordnet ist, also die gleiche y-Koordinate aufweist.As aligned with the rotary plain bearings a scissors joint is to be understood, which is arranged in a x-direction on a virtual axis with the rotary slide bearings, that has the same y-coordinate.
Gemäß einem weiteren Ausführungsbeispiel sind die Abstufungen entsprechend 100 bis 200 Prozent einer Dicke eines jeweiligen Scherenarms ausgebildet, bevorzugt 100 bis 150 Prozent, weiter bevorzugt 110 bis 130 Prozent. Die Abstufungen können auch lediglich im Bereich von 100 Prozent oder knapp über 10 Prozent der Dicke ausgebildet sein, um sicherzustellen, dass die Scherenarme nicht miteinander kollidieren. Um einen leichtgängigen Mechanismus bereitzustellen, ist es jedoch vorteilhaft, wenn die Abstufungen etwas stärker ausgebildet sind als die Dicke der Scherenarme. Auf diese Weise können die Scherenarme einander hintergreifen, ohne beim Verschwenken aufeinander zu reiben.According to a further embodiment, the gradations are formed corresponding to 100 to 200 percent of a thickness of a respective scissor arm, preferably 100 to 150 percent, more preferably 110 to 130 percent. The shades may also be formed only in the range of 100 percent or just over 10 percent of the thickness to ensure that the scissor arms do not collide with each other. However, to provide a smooth mechanism, it is advantageous if the gradations slightly stronger than the thickness of the scissor arms. In this way, the scissor arms can engage behind each other without rubbing each other during pivoting.
Gemäß einem weiteren Ausführungsbeispiel sind die Scherenarme als ein erster äußerer Scherenarm unter einem ersten mittleren Scherenarm unter einem zweiten mittleren Scherenarm unter einem zweiten äußeren Scherenarm zueinander angeordnet und so gelagert, dass in einem zusammengeschobenen Zustand der Parallel-Ausstellvorrichtung der erste äußere Scherenarm den ersten mittleren Scherenarm und der zweite mittlere Scherenarm den zweiten äußeren Scherenarm jeweils im Bereich der axial verschiebbaren Drehlagerung hintergreift. Hierdurch kann eine stabile Verschränkung der Scherenarme untereinander erfolgen und alle Gelenke können übereinander angeordnet sein bzw. in derselben Richtung verlagert werden, wodurch sich eine gleichlaufende und homogen verlagernde Mechanik ergibt, bei welcher unabhängig von dem Abstand der Führungen zueinander die Stabilität zumindest annähernd in gleichem Maße gewahrt bleibt. Dabei drehen sich die äußeren Scherenarme unabhängig von ihrer Ausrichtung um Momentanpole, die jeweils mit den Drehlagerungen zusammenfallen, und die mittleren Scherenarme drehen um Momentanpole, die jeweils nicht ortsfest sind, sondern entlang der Führung wandern.According to a further embodiment, the scissor arms are arranged as a first outer scissor arm under a first middle scissor arm under a second middle scissor arm under a second outer scissor arm to each other and stored so that in a collapsed state of the parallel Ausstellvorrichtung the first outer scissor arm, the first middle scissor arm and the second middle scissor arm engages behind the second outer scissor arm in each case in the region of the axially displaceable pivot bearing. In this way, a stable entanglement of the scissor arms can be done with each other and all joints can be superimposed or shifted in the same direction, resulting in a concurrent and homogeneously displacing mechanism, in which regardless of the distance of the guides to each other, the stability at least approximately the same extent is maintained. Irrespective of their orientation, the outer scissor arms rotate about instantaneous poles, which respectively coincide with the rotary bearings, and the middle scissor arms rotate about instantaneous poles, which are not stationary in each case but travel along the guide.

In der
Die zwei Scherenarmpaare 31, 32 bzw. 33, 34 sind in einem ersten freien endseitigen Scherengelenk 35a sowie einem zweiten freien endseitigen Scherengelenk 35b aneinander gekoppelt. Das erste freie endseitige Scherengelenk 35a ist in einer x-Richtung verlagerbar, und das zweite freie endseitige Scherengelenk 35b ist sowohl in einer x-Richtung als auch in einer y-Richtung verlagerbar, insbesondere simultan mit den Dreh-Gleitlagerungen 38. Die Scherenarme eines jeweiligen Scherenarmpaares sind jeweils über ein zentrisches Scherengelenk 36 aneinander gekoppelt. Ferner ist der erste äußerer Scherenarm 31 mit dem zweiten äußeren Scherenarm 34 gekoppelt, und der erste mittlere Scherenarm 32 ist mit dem zweiten mittleren Scherenarm 33 gekoppelt. Dabei weist jeder Scherenarm eine Ausnehmung 31.1, 32.1, 33.1, 34.1 sowie eine Abstufung 31.2, 32.2, 33.2, 34.2. Bei allen Scherenarmen sind die Ausnehmungen und Abstufungen an demselben freien Ende angeordnet, d.h., die Scherenarme sind so aneinander montiert, dass ihre Ausnehmung bzw. Abstufung jeweils an dem freien Ende angeordnet sind, welches im zusammengeschobenen Zustand mit dem entsprechenden freien Ende der anderen Scherenarme zusammenfällt. Dadurch können die freien endseitigen Scherengelenke 35a, 35b ein derselben xy-Ebene angeordnet werden. Die Ausnehmungen sind rechteckig, und sie weisen einen äußeren Randbereich 34.3 auf, welcher exemplarisch an der Ausnehmung des zweiten äußeren Scherenarms 34 mit Bezugsziffer versehen ist. Die Ausnehmung ist jeweils im Bereich des Randbereichs vorgesehen, insbesondere beabstandet zum Randbereich an einem Teil des Scherenarms, an welchem die Ausnehmung vorgesehen ist. Die Scherenarme weisen eine Breite b2 auf. Durch die Ausnehmungen und Abstufungen ist es möglich, die Parallel-Ausstellvorrichtung 1 in einem zusammengeschobenen Zustand auf eine Breite im Bereich der Breite b2 zu bringen, so dass nur wenig Platz erforderlich ist bzw. die Parallel-Ausstellvorrichtung 1 auch bei sehr dünnen bzw. schmalen bzw. flachen Fensterflügeln verwendet werden kann.
