Description

Die Erfindung richtet sich auf ein Kippgelenk für eine Kassettenmarkise nach dem Oberbegriff von Anspruch 1.The invention relates to a tilt joint for a cassette awning according to the preamble of claim 1.

Bei derartigen Kassettenmarkisen ist die Tuchwelle ebenso wie das Markisentuch im eingefahrenen Zustand in einer allseitig geschlossenen Kassette untergebracht, wobei der vertikale Abschluß der freien Stirnseite der Kassette durch eine Ausfallblende gebildet wird, welche mit dem freien Ende der Gelenkarme verbunden ist und beim Einfahren der Gelenkarme die Kassette abschließt. Um dieses Abschließen einwandfrei sicherzustellen und trotzdem zu ermöglichen, daß die Gelenkarme der Markise im ausgefahrenen Zustand gegen die horizontale Richtung geneigt sind, muß die Lagerung der Gelenkarme in der letzten Phase des Einschwenkens eine Schwenkbewegung aus der geneigten in die horizontale Lage durchführen können. Andererseits muß sichergestellt sein, daß im ausgefahrenen Zustand diese Schwenkbewegung zuverlässig unterbunden wird, damit die ausgefahrene Markise nicht unter dem Einfluß äußerer Kräfte, insbesondere von Wind, Schwingungen um diese Schwenkachse ausführen kann. Zu diesem Zweck sind bei bekannten Kassettenmarkisen sogenannte Windbremsen in unterschiedlichen Ausführungsformen bekannt. Diese Windbremsen umfassen im wesentlichen eine Rasteinrichtung, welche im ausgefahrenen Zustand einrastet und so die Gelenkarme in ihrer geneigten Lage fixiert. Als weitere Anforderung an die Kippgelenke von Gelenkarmmarkisen kommt hinzu, daß der Neigungswinkel im ausgefahrenen Zustand einstellbar sein sol.In the case of cassette awnings of this type, the fabric shaft and the awning fabric in the retracted state are accommodated in a cassette which is closed on all sides, the vertical closure of the free end face of the cassette being formed by a dropout panel which is connected to the free end of the articulated arms and which when the articulated arms are retracted Cassette locks. In order to ensure this locking properly and still enable the articulated arms of the awning to be inclined against the horizontal direction in the extended state, the storage of the articulated arms in the last phase of the swiveling in must be able to carry out a swiveling movement from the inclined into the horizontal position. On the other hand, it must be ensured that this pivoting movement is reliably prevented in the extended state, so that the extended René awning can not perform vibrations about this pivot axis under the influence of external forces, especially wind. For this purpose, so-called wind brakes in various embodiments are known in known cassette awnings. These wind brakes essentially comprise a locking device which locks in the extended state and thus fixes the articulated arms in their inclined position. Another requirement for the tilting joints of articulated arm awnings is that the angle of inclination should be adjustable when extended.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine möglichst einfache und damit wartungsfreundliche und kostengünstig herstellbare Ausführungsform eines Kippgelenks zu schaffen, welches trotzdem eine den hohen auftretenden Kräften gerecht werdende Stabilität aufweist und insbesondere eine sichere Festlegung im ausgefahrenen Zustand gestattet, wobei gleichzeitig eine bequeme Neigungsverstellung in jeder Position von vorne möglich sein soll.Proceeding from this, the invention has for its object to provide a simple and thus maintenance-friendly and inexpensive to manufacture embodiment of a tilting joint, which nevertheless has a stability that meets the high forces involved and in particular allows a secure fixing in the extended state, while at the same time allowing a comfortable inclination adjustment should be possible from the front in any position.

Diese Aufgabe wird erfindungsgemäß durch die Maßnahmen nach dem kennzeichnenden Teil von Anspruch 1 gelöst. Die Ausbildung der Rasteinrichtung zwischen der Stellschraube für die Neigungsverstellung und der einen Gelenkarm tragenden, schwenkbar gelagerten Sperrschwinge ermöglicht es, problemlos von vorne die Stellschraube in jeder Position zu betätigen und eine Neigungseinstellung vorzunehmen, und zwar insbesondere auch wenn die Markise nur wenig ausgefahren ist. Der erfindungsgemäß vorgesehene, durch eine Anschlagschulter eines Gelenkarms betätigbare Sperrbolzen ermöglicht das Auslösen der die Neigung im Ausfahrzustand fixierenden Rasteinrichtung bei einer exakt definierbaren Bewegungsphase der Einschwenkbewegung. Auf diese Weise läßt sich erreichen, daß die Rasteinrichtung zwar genau dann freigegeben ist, wenn dies zum Einschieben der Ausfallblende in die Kassette erforderlich ist, daß aber in der umgekehrten Bewegungsrichtung sofort ein Einrasten erfolgt, wenn die Ausfallblende sich von der Kassette entfernt.This object is achieved by the measures according to the characterizing part of claim 1. The design of the locking device between the adjusting screw for the inclination adjustment and the pivoting locking rocker bearing an articulated arm makes it possible to operate the adjusting screw in any position from the front and to make an inclination adjustment, in particular even when the awning is only slightly extended. The locking pin provided according to the invention and which can be actuated by a stop shoulder of an articulated arm enables the latching device which fixes the inclination in the extended state to be triggered during a precisely definable movement phase of the on swivel motion. In this way, it can be achieved that the latching device is released exactly when this is necessary for inserting the dropout cover into the cassette, but that in the opposite direction of movement there is an immediate snap-in when the dropout cover moves away from the cassette.

Anspruch 2 gibt eine besonders einfache, leicht herstellbare Ausbildung der Rasteinrichtung an.Claim 2 specifies a particularly simple, easy to manufacture design of the locking device.

Die gemäß Anspruch 3 vorgesehene Einstellschraube ermöglicht eine genaue Festlegung, bei welchem Schwenkwinkel der Gelenkarme die Anschlagschulter den Sperrbolzen betätigt, d.h. das erfindungsgemäße Kippgelenk kann einfach an bestimmte geometrische Verhältnisse, insbesondere vorgegebene Kassettengrößen angepaßt werden.The adjusting screw provided according to claim 3 enables a precise determination of the pivoting angle of the articulated arms at which the stop shoulder actuates the locking pin, i.e. the tilt joint according to the invention can easily be adapted to certain geometric conditions, in particular predetermined cassette sizes.

Die Ansprüche 4 und 5 geben Möglichkeiten zur Erzielung einer koordinierten Bewegung zwischen Sperrbolzen und Markisenarm an.Claims 4 and 5 indicate possibilities for achieving a coordinated movement between the locking pin and the awning arm.

Als günstig erweist es sich, die Federbeaufschlagung des Sperrbolzens in die Sperrichtung gemäß Anspruch 6 zu realisieren.It has proven to be advantageous to implement the spring action of the locking bolt in the locking direction according to claim 6.

Das eine Ende 42 des Sperrbolzens 4o wird von einer Schraubenfeder 43 beaufschlagt, welche in der Bohrung 38 angeordnet ist und sich gegen die Stirnwand 44 dieser Bohrung abstützt. Die Schraubenfeder 44 wird von einer Einstellschraube 45 durchsetzt, deren Kopf 46 die Bohrung 38 übergreift, und deren inneres Ende in eine Gewindebohrung 47 in dem Sperrbolzen 4o eingreift. Durch eine Betätigung der Einstellschraube 45 mittels des Kopfes 46 kann somit die Position des Sperrbolzens 4o in der Bohrung 38 eingestellt werden. Auch der Sperrbolzen 4o weist eine äußere Ausnehmung 48 in Form einer Ringnut auf. Die Durchmesser d1 der Stellschraube 28 im Bereich der seitlichen Ausnehmung 37 und der Durchmesser d2 des Sperrbolzens 4o im Bereich der Ausnehmung 48 bzw. der seitliche Versatz der Längsachsen 41 der Stellschraube 28 und der Längsachse 49 des Sperrbolzens 4o sind so aufeinander abgestimmt, daß dann, wenn die Ausnehmung 48 die Längsachse 41 der Stellschraube 28 überdeckt, der Sperrbolzen 4o frei in Richtung der Längsachse 41 der Stellschraube 28 beweglich ist, daß im anderen Fall aber der Grundkörper des Sperrbolzens 4o die Ausnehmung 37 der Stellschraube 28 so durchsetzt, daß eine Rastwirkung eintritt, d.h. daß eine Bewegung des Sperrbolzens 4o und der damit verbundenen Teile in Richtung der Längsachse 41 nicht möglich ist.One end 42 of the locking bolt 4o is acted upon by a helical spring 43, which is arranged in the bore 38 and is supported against the end wall 44 of this bore. The helical spring 44 is penetrated by an adjusting screw 45, the head 46 of which engages over the bore 38, and the inner end of which engages in a threaded bore 47 in the locking bolt 4o. By actuating the adjusting screw 45 by means of the head 46, the position of the locking bolt 4o in the bore 38 can thus be adjusted. The locking pin 4o also has an outer recess 48 in the form of an annular groove. The diameter d 1 of the set screw 28 in the region of the lateral recess 37 and the diameter d 2 of the locking bolt 4o in the region of the recess 48 or the lateral offset of the longitudinal axes 41 of the set screw 28 and the longitudinal axis 49 of the locking bolt 4o are coordinated so that when the recess 48 has the longitudinal axis 41 the set screw 28 covers, the locking pin 4o is freely movable in the direction of the longitudinal axis 41 of the set screw 28, but in the other case, the base body of the locking pin 4o penetrates the recess 37 of the set screw 28 so that a locking effect occurs, ie that a movement of the locking pin 4o and the associated parts in the direction of the longitudinal axis 41 is not possible.

Das freie Ende 5o des Sperrbolzens 4o liegt in einem Winkelbereich α kurz nach Beginn des Ausfahrens bzw. vor Beendigung des Einfahrens einer Anschlagschulter 51 beaufschlagt durch die Kraft der Schraubenfeder 43 an. Außerhalb dieses Bereichs stehen das Ende 5o und die Anschlagschulter 51 nicht in Berührungskontakt.The free end 5o of the locking bolt 4o lies in an angular range α shortly after the start of the extension or before the end of the retraction of a stop shoulder 51 acted upon by the force of the coil spring 43. Outside this range, the end 50 and the stop shoulder 51 are not in contact.

Die Arbeitsweise des erfindungsgemäßen Kippgelenks läßt sich am besten anhand von Fig. 2 veranschaulichen:

  • Im eingefahrenen Zustand der Markise liegt die Achse 52 des Gelenkarms 15 parallel zur Achse 49 des Sperrbolzens. Der Sperrbolzen nimmt eine solche Position ein, daß die Ausnehmung 48 über der Längsachse 41 der Stellschraube 28 liegt. Die Schraubenfeder 43 ist komprimiert. Bei Beginn des Ausfahrens von dem in Fig. 1 dargestellten Zustand kann nun eine Schwenkbewegung nach links unten in Fig. 1 um die Achse S1 beginnen, d.h. die Ausfallblende 11 bewegt sich von der Kassette 3 weg. Mit Zunahme des Winkels α, d.h. mit fortschreitendem Ausfahren der Gelenkarme 15, wird der Sperrbolzen 4o unter dem Einfluß der Schraubenfeder 43 gegen die wegwandernde Anschlagschulter 51 des Gelenkarms 15 in Fig. 2 nach oben gedrückt. Dadurch gelangt nach Erreichen eines bestimmten Winkels die Ausnehmung 48 des Sperrbolzens 4o außerhalb des Bereichs der Längsachse 41 der Stellschraube 28 und die im Durchmesser nicht reduzierte Mantelfläche des Sperrbolzens 4o greift nun in die Ausnehmung 37, welche durch eine Ringnut gebildet wird, der Stellschraube 28 ein. Dies bedeutet aber, daß nach Erreichen dieses fortgeschrittenen Ausfahrzustandes eine Rastwirkung eintritt, d.h. der Grundkörper des Sperrbolzens 4o wirkt in Verbindung mit der Ausnehmung 37 als Rasteinrichtung. Beim fortschreitenden Ausfahren des Gelenkarms 15 gelangt dann zwar die Anschlagschulter 51 außer Eingriff mit dem Ende 5o des Sperrbolzens, der Sperrbolzen bleibt aber aufgrund der Wirkung der Schraubenfeder 43 in seiner Sperrposition (oben in Fig. 2).
The method of operation of the tilt joint according to the invention can best be illustrated with reference to FIG. 2:
  • In the retracted state of the awning, the axis 52 of the articulated arm 15 is parallel to the axis 49 of the locking bolt. The locking pin assumes such a position that the recess 48 lies over the longitudinal axis 41 of the set screw 28. The coil spring 43 is compressed. At the beginning of the extension from the state shown in FIG. 1, a pivoting movement to the left downward in FIG. 1 can now begin about the axis S 1 , ie the dropout cover 11 moves away from the cassette 3. As the angle α increases, ie as the articulated arms 15 progressively extend, the locking pin 4o is pressed upwards under the influence of the helical spring 43 against the migrating stop shoulder 51 of the articulated arm 15 in FIG. 2. As a result, the recess 48 of the locking bolt reaches after reaching a certain angle 4o outside the area of the longitudinal axis 41 of the set screw 28 and the circumferential surface of the locking bolt 4o which is not reduced in diameter now engages in the recess 37, which is formed by an annular groove, of the set screw 28. However, this means that after reaching this advanced extension state, a locking action occurs, ie the base body of the locking bolt 4o acts in conjunction with the recess 37 as a locking device. As the articulated arm 15 progressively extends, the stop shoulder 51 disengages from the end 50 of the locking bolt, but the locking bolt remains in its locking position due to the action of the coil spring 43 (top in FIG. 2).

Beim Einfahren der Markise wiederholt sich der vorstehend beschriebene Vorgang in umgekehrter Richtung. Insbesondere aus Fig. 2 wird deutlich, daß unabhängig von der Wirkungsweise des Kippgelenks über die Stellschraube 28 eine Neigungseinstellung von vorne in bequemer Weise durchgeführt werden kann. Die Einstellschraube 45 ermöglicht eine Einstellung des gewünschten Auslösewinkels α, z.B. in Abhängigkeit von der Größe der Kassette 3.When retracting the awning, the process described above is repeated in the opposite direction. In particular, it is clear from Fig. 2 that regardless of the operation of the tilt joint via the screw 28, an inclination adjustment from the front can be carried out in a convenient manner. The adjusting screw 45 enables the desired trigger angle α, e.g. depending on the size of the cassette 3.

Aus der vorstehenden Beschreibung ergibt sich, daß durch die erfindungsgemäße Konstruktion sichergestellt ist, daß auftretende Kräfte, z.B. durch Windböen, im ausgefahrenen Zustand sicher abgefangen werden, während in der Anfangs- bzw. Endphase der Aus- bzw. Einfahrbewegung die Ausfallblende problemlos sich an die Kassette anschließen kann.From the above description it follows that the construction according to the invention ensures that occurring forces, e.g. can be safely intercepted by gusts of wind in the extended state, while in the initial or final phase of the extending or retracting movement the front cover can easily connect to the cassette.
