Description
Das technische Gebiet der Erfindung sind die verstellbaren Ausstellscheren, mit denen Flügel oder Klappen geöffnet und geschlossen werden können, wie in der EP 94 11 6349.5 ursprünglich beschrieben, veröffentlicht unter EP 710 759. Dabei handelt es sich um einen Stand der Technik nach Art 54(3) EPÜ.The technical field of the invention are the adjustable stay scissors with which wings or flaps can be opened and closed, as in the EP 94 11 6349.5 originally described, published under EP 710 759. This is state of the art according to Art 54 (3) EPC.
Nur linear bewegliche Schub/Zughülsen sind aus der DE 35 03 806 C2 und der DE 43 22 133 C2 dem Fachmann offenbart. Dort wird jeweils ein Schubmotor in einem zylindrischen Gehäuse vorgeschlagen, in dem längsverschieblich eine in ihrer Länge veränderliche Schub/Zughülse vorgesehen ist, die an ihrem Ende eine Anlenkstelle oder -öse aufweist. Mit dieser Öse können Dachluken direkt oder über einen zwischengeschalteten Schlitten mit einem Lagerbock, welcher Schlitten längsbeweglich an der Dachluke befestigt ist, in ihrer Öffnungsstellung verändert werden. Beide Druckschriften befassen sich nicht mit der Ausbildung von Scheren, die zumindest zwei gelenkig miteinander verbundene Scherenarme haben, die in ihrer Winkelstellung α (alpha) gegeneinander veränderbar sind.Only linearly movable push / pull sleeves are disclosed to those skilled in the art from DE 35 03 806 C2 and DE 43 22 133 C2 . There, a thrust motor is proposed in a cylindrical housing, in which a longitudinally displaceable thrust / pull sleeve is provided, which has an articulation point or eyelet at its end. With this eyelet, the roof hatches can be changed in their open position either directly or via an interposed slide with a bearing block, which slide is attached to the roof hatch in a longitudinally movable manner. Neither publication is concerned with the formation of scissors which have at least two articulated scissor arms which can be changed relative to one another in their angular position α (alpha).
Üblicherweise weisen Oberlichtöffner-Scheren zwei Scherenarme auf, von denen der eine in einem Scherenhalter fest am Blendrahmen oder an der Zarge befestigt ist und der andere über ein Gelenk dem fest angeordneten Scherenarm gegenüber verschwenkbar ist. Die Ausstellbewegung wird erreicht durch eine Kupplungsmechanik, die zwischen dem festen und dem beweglichen Scherenarm angebracht ist und die zumeist eine Mehrzahl von Lenkern aufweist, die von einer Stell- oder Zugstange betrieben werden. Die Zugstange kann elektromotorisch angetrieben sein. Aus der Natur der Sache haben solche Scheren oft ein erhebliches inneres Spiel, da mit ihnen sowohl die Ausstellbewegung als auch eine leichte Verschwenkbewegung um die Stellstange ausgeglichen werden muß. Dieser "relativ lockere Aufbau" von solcher Art angetriebenen Scheren verhindert es, daß diese Scheren vielseitig einsetzbar sind, ihr Anwendungsbereich ist zumeist auf das Öffnen von Oberlichtfenstern beschränkt, Kuppeln oder Dachfenster können mit diesen Scheren aufgrund ihrer inneren Instabilität nicht (aufwärts) geöffnet werden.Fanlight scissors usually have two scissor arms, one of which one of which is firmly attached to the frame or frame in a scissor holder is and the other via a joint opposite the fixed scissor arm is pivotable. The opening movement is achieved by a Coupling mechanism between the fixed and the movable scissor arm is attached and which usually has a plurality of handlebars by one Actuator or pull rod operated. The pull rod can be electromotive be driven. Because of the nature of the matter, such scissors often have one considerable internal play, since with them both the exhibition movement and one slight pivoting movement around the adjusting rod must be compensated. This "relatively loose structure" of scissors driven in this way prevents it is that these scissors are versatile, their field of application mostly limited to opening skylight windows, domes or Skylights cannot with these scissors due to their internal instability can be opened.
Die Erfindung geht von der Problemstellung aus, eine präzise betätigbare Ausstellschere zu schaffen, die kompakt und vielseitig zugleich ist. Trotz ihres kompakten Aufbaus und der vielseitigen Verwendbarkeit soll sie eine hohe Öffnungs- und Schließkraft aufbringen, ohne daß der Verwender dieselbe hohe Kraftaufwendung einsetzen muß. The invention is based on the problem of creating a precisely operated scissors that is compact and versatile at the same time. Despite its compact structure and its versatility, it should have a high opening and closing force without the user having to use the same high level of force.
Diese Aufgabe wird dann gelöst, wenn die motorisch verstellbare (d.h. im Öffnungswinkel α verstellbare) Schere drei Scherenarme aufweist, von denen der eine Scherenarm als Ausstellarm in seiner Länge veränderbar ist (Anspruch 1). Der in seiner Länge veränderbare Scherenarm ist der innere Scherenarm und ist zwischen den beiden anderen Scherenarmen, die die äußeren Scherenarme bilden, angelenkt. Er wirkt als Ausstellhebel, indem seine beiden Anlenkstellen von dem gemeinsamen Gelenk der beiden äußeren Scherenarme (dem "äußeren" Gelenk) entfernt sind. Das gemeinsame Gelenk der äußeren Scherenarme ist an jeweils einem Ende des äußeren Scherenarmes vorgesehen.This task is solved when the motorized (i.e. in Opening angle α adjustable) scissors has three scissor arms, one of which a scissor arm can be changed in length as a raising arm (claim 1). The length changeable scissor arm is the inner scissor arm and is between the two other scissor arms, which form the outer scissor arms, articulated. It acts as a lever, by its two articulation points from the joint the two outer scissor arms (the "outer" joint) are removed. The joint joint of the outer scissor arms is at one end of each outer scissor arm provided.
In dem inneren Scherenarm ist ein Elektromotor angeordnet (Anspruch 3), der über einen Bewegungs-Umsetzer (Anspruch 2) einen Hülsenabschnitt heraus- und hereinfährt (Anspruch 8,9). In diesem Ausstellhebel wird damit die Öffnungskraft erzeugt, sie kann präzise auf die äußeren Scherenarme übertragen werden. Die Kraftübertragung ist damit unmittelbar, direkt und genau an dem Ort, wo sie benötigt wird. Zusätzliche Übertragungselemente, wie Stangen, Hebel oder Betätigungsschienen, werden nicht erforderlich, ebenso ist es entbehrlich, Bolzen/Schlitz-Führungen einzusetzen, die eine bestimmte Kurvenform des Schlitzes haben müssen, um eine mechanische Verklemmung zu vermeiden.An electric motor is arranged in the inner scissor arm (claim 3) a motion converter (claim 2) out and a sleeve section drives in (claim 8.9). The opening force is thus in this opening lever generated, it can be transferred precisely to the outer scissor arms. The Power transmission is thus immediate, direct and exactly where it is is needed. Additional transmission elements such as rods, levers or Actuating rails are not required, it is also unnecessary Use bolt / slot guides that have a specific curve shape Must have slot to avoid mechanical jamming.
Der Abstand (x1,y1) der Anlenkung des in seiner Länge veränderbaren inneren Scherenarms an den beiden äußeren Scherenarmen ist deutlich unterschiedlich. An dem einen Scherenarm, in dem der innere Scherenarm in geschlossener Stellung zu liegen kommt, ist der motorisch veränderliche Ausstellarm an dem Ende angelenkt, das dem gemeinsamen Gelenk der äußeren Scherenarme gegenüberliegt (Abstand y1 vom äußeren Gelenk). An dem anderen äußeren Scherenarm ist der motorisch veränderliche Ausstellhebel (der innere Scherenarm) in der Nähe des erwähnten gemeinsamen Gelenkes zwischen den äußeren Scherenarmen angelenkt (Abstand x1).The distance (x1, y1) of the linkage of the interior, which is variable in length The scissor arm on the two outer scissor arms is significantly different. On the one scissor arm in which the inner scissor arm in the closed position the motor-driven extension arm comes to rest at the end articulated, which is opposite the common joint of the outer scissor arms (Distance y1 from the outer joint). On the other outer scissor arm is the Motor-driven opening lever (the inner scissor arm) near the mentioned joint articulated between the outer scissor arms (Distance x1).
Die Anlenkstellen des inneren Scherenarms an den äußeren Scherenarmen sind unverschieblich (Anspruch 4). Dadurch wird deutlich, daß Zapfen/Schlitz-Führungen nicht erforderlich sind. Alle Gelenke, auch das "äußere Gelenk" zwischen den äußeren Scherenarmen sind unverschieblich, gleichwohl wird ein großer Ausstellwinkel α erreicht. The articulation points of the inner scissor arm on the outer scissor arms are immovable (claim 4). This makes it clear that pin / slot guides are not required. All joints, including the "outer joint" between the outer scissor arms are immovable, nevertheless a large opening angle α reached.
Wenn die äußeren Scherenarme U-förmig gestaltet sind (Anspruch 5), können sie im geschlossenen Zustand den dann leicht schräg liegenden motorisch veränderbaren inneren Ausstellarm aufnehmen und abdecken. Die Schere hat dann auch in geschlossenem Zustand ein optisch vorbildliches Erscheinungsbild, sie ragt nicht ab von dem Anbringungsort und enthält keine unschönen wegragenden Stangen oder Gewinde.If the outer scissor arms are U-shaped (claim 5), they can in the closed state, the then slightly inclined motor Pick up and cover changeable inner extension arm. Then the scissors have Even when closed, it has a visually exemplary appearance, it sticks out does not depend on the place of installation and contains no unsightly protruding ones Rods or threads.
Anspruch 6 umschreibt das "äußere Gelenk", zwischen den beiden äußeren Scherenarmen. Um in Schließstellung den einen äußeren Scherenarm auf dem anderen äußeren Scherenarm bündig zu lagern, ist ein winkelig angebrachtes Ausgleichsstück ("Winkelstück") an einem der beiden äußeren Scherenarme vorgesehen, das in etwa die Höhe des anderen Scherenarmes aufweist (Anspruch 7,11).Claim 6 describes the "outer joint", between the two outer Scissor arms. To in the closed position the one outer scissor arm on the To store the other outer scissor arm flush is an angled one Compensating piece ("angle piece") on one of the two outer scissor arms provided, which has approximately the height of the other scissor arm (Claim 7.11).
Die beiden äußeren Scherenarme können verschieden lang gestaltet sein (Anspruch 8). Mit dieser Ausbildung können die Hebel- und Kraftverhältnisse für das Öffnen und Schließen eingestellt werden; eine Verkürzung des einen Arms führt zu höherer Öffnungskraft bei reduzierter Öffnungsweite. Der innere Scherenarm kann etwa die Länge des kürzeren der beiden äußeren Scherenarme aufweisen, ist aber am äußeren Ende des längeren Scherenarms angelenkt, womit in der Schließstellung der äußeren Arme auch der Abstand x1 des Anlenkpunktes des anderen Endes des inneren Scherenarmes von dem äußeren Gelenk festliegt.The two outer scissor arms can be of different lengths (Claim 8). With this training, the leverage and power relationships for opening and closing can be set; a shortening of one arm leads to higher opening force with reduced opening width. The inner one Scissor arm can be about the length of the shorter of the two outer scissor arms have, but is articulated at the outer end of the longer scissor arm, with what in the closed position of the outer arms also the distance x1 of the articulation point the other end of the inner scissor arm is fixed by the outer joint.
Die Anbringung der elektromotorisch betätigbaren Schere an einem Blendrahmen und einem Flügel geschieht mit einer Zapfen-Aufnahme (zur Aufnahme eines Flügelbock-Zapfens) an einem freien Ende der äußeren Scherenarme und mit einem Scharniergelenk am anderen freien Ende der äußeren Scherenarme (Anspruch 10). Meist wird das Scharniergelenk am Blendrahmen zu befestigen sein, während der Flügelbock mit seinem aufragenden Zapfen von der Bohrung am anderen Scherenarm leicht verkippbar aber dennoch in Bewegungsrichtung der Scherenarme unverschieblich aufgenommen wird. The attachment of the electric scissors to a frame and a wing is done with a pin receptacle (for receiving a Wing bracket pin) at one free end of the outer scissor arms and with one Hinge joint at the other free end of the outer scissor arms (claim 10). Most of the time, the hinge joint will have to be attached to the frame during the Wing bracket with its upstanding pin from the hole on the other Scissor arm easily tiltable but still in the direction of movement Scissor arms are immovably received.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispieles erläutert und ergänzt.

Zur Beschreibung motorischer Scheren wird vollumfänglich auf die EP 94 11 6349.5 verwiesen, insbesondere die Figur 1, die Figur 1a (zum Aufbau einer Schere mit drei Scherenarmen), als auch auf die Figur 4e und 5b hinsichtlich der Art der Anbringung und der Verwendungsweisen solcher Scheren. Auch die Bezugsziffern der Beschreibung dieses Beispiels der Erfindung sind im wesentlichen gleich gewählt, wie die der erwähnten europäischen Anmeldung.For a description of motorized scissors, full reference is made to EP 94 11 6349.5 , in particular FIG. 1, FIG. 1a (for the construction of scissors with three scissor arms), and also FIGS . 4e and 5b with regard to the type of attachment and the use of such scissors , The reference numbers in the description of this example of the invention are chosen essentially the same as those of the European application mentioned.
Ein erster äußerer Scherenarm 20 ist in Figur 1 über ein Gelenk 31b mit dem
anderen äußeren Scherenarm 10 verbunden. Das Gelenk ist an jeweils einem Ende
dieser beiden äußeren Scherenarme angebracht. Im Abstand von dem Gelenk, d.h.
in deutlich unterschiedlichem Abstand x1, y1, sind die beiden Enden einer
motorisch in ihrer Länge veränderaren Stellstange 30 angelenkt. Diese
Gelenkpunkte 31a und 31c sind reine Schwenklager, die unverschieblich sind. Der
motorisch verlängerbare und verkürzbare innere Ausstellarm 30 bewegt sich bei
seiner Verlängerung um beide Schwenklager und öffnet bzw. schließt dabei die
äußeren Arme 10,20 um den Öffnungswinkel α.A first
Der Aufbau des inneren Arms ist in Figur 2 näher erläutert. Ein Motor 40 ist an
einem Ende angeordnet, der über ein Puffer oder Getriebe 42 eine Mutter 12
antreibt, die unverdrehbar in einer Hülse 41a angebracht ist. Zum Antrieb der
Stellmutter 12 dient eine Gewindestange 41, die der Motor 40 oder das
Getriebe 42 direkt antreibt.The structure of the inner arm is explained in more detail in Figure 2 . A
Am vorderen Ende der Stellstange 41a ist eine Öse 41b für die Bildung des ersten
inneren Gelenks 31a, während am entgegengesetzten Ende, hinter dem Motor 40,
eine zweite Öse vorgesehen ist, um das andere innere Gelenk 31c an dem anderen
äußeren Arm zu realisieren. At the front end of the adjusting rod 41a is an
Bei der Öffnung bewegt sich der innere, in seiner Länge veränderliche Arm 30 nur
leicht aus seiner Ruhelage, die etwa parallel zu den äußeren Scherenarmen 10,20
ist. Gleichzeitig wird aber der zweite äußere Scherenarm deutlich geöffnet, so daß
eine Öffnungsweite von nahezu 90° erreicht wird. Die unterschiedlichen Abstände
der "inneren Anlenkpunkte" 31a,31c zum "äußeren Gelenk" 31b bestimmt den
Verlauf des Öffnungswinkels α und die maximale Öffnungsweite.When opening, the
Am freien Ende jeden äußeren Scherenarmes 10,20 ist ein Anbringungsorgan
vorgesehen, das einmal kugelgelenkartig 21 ausgebildet ist und einmal
scharnierartig 11 ausgebildet ist. Mit dem Scharniergelenk 11 wird der eine (meist
der längere) Scherenarm am Blendrahmen befestigt. Die Kugelgelenk-Lagerung 21
kann eine Aufnahmebohrung für den Kegel eines Flügelbocks sein.At the free end of each
Wird die beschriebene Schere 19 so an einem zu öffnenden Fenster angeordnet,
daß ihre Öffnungsbewegung und der zugehörige Öffnungswinkel mit der
Öffnungsbewegung und dem zugehörigen Öffnungswinkel des Flügels
korrespondiert (Scherenarme senkrecht zur Drehachse des Flügels), so kann das
Gelenk 11 ein Schwenkgelenk mit einer Achse sein. Wird dagegen die
Scherenebene (die Ebene der Scherenarme 10,20 bei ihrer Öffnungsbewegung)
parallel zur Schwenk- oder Kippachse des Flügels gelegt, greift also die Schere z.B.
mittig an der oberen Kante des Flügels an, der sich öffnet, so wird das Gelenk 11
zwei zueinander senkrechte Schwenkachsen haben. Damit wird ein inneres Spiel
