A pivotal hinge for an arm of an awning, wherein a supporting block is tightly clamped on a rectangular supporting tube and carries a pivotal bracket swingable and lockable about an axle disposed in parallel with the supporting tube. The pivotal hinge is adjustable in a simple manner by a readily available tool and has high stability, particularly rigidity against torsion. The supporting block is defined by a yoke including two legs joined by a central web, one leg being defined by two parallel webs and a cross web connecting same. A supporting trunnion is carried within a pair of eyes formed in spaced projections extending beyond the central web for pivotally supporting the pivotal bracket. A threaded sleeve is rotatably supported in a guide passage provided in the cross web, with a threaded bolt being engaged through the threaded sleeve and having one end pivotally connected to the pivotal bracket.

Description

Die Erfindung betrifft ein Armlager für eine Gelenkarmmarkise, bei dem ein als Bügel mit zwei durch einem Mittelsteg verbundenen Schenkeln ausgebildeter Tragbock, dessen einer Schenkel zwei parallele Stege aufweist, auf einem Vierkanttragrohr festspannbar ist und auf einem Tragzapfen in über den Mittelsteg vorstehenden Augen einen Lagerbock aufnimmt, der auf einem Zapfen ein Ende eines zwischen den Stegen lieenden Gewindebolzens gelenkig aufnimmt, der außerdem in eine Gewindehülse eingreift.The invention relates to an arm bearing for an articulated arm awning, in which a support bracket formed as a bracket with two legs connected by a central web, one arm of which has two parallel webs, can be clamped on a square support tube and receives a bearing block on a support pin in eyes protruding above the central web which articulates an end of a threaded bolt lying between the webs on a pin and which also engages in a threaded sleeve.

Eine derartige Gelenkarmmarkise ist aus der EP-A-0 084 076 bekannt. Dort ist über ein von einer Welle antreibbares Schneckengetriebe eine Gewindestange verstellbar. Die gesamte Zugbelastung der Gelenkarme hängt an der Gewindestange. Infolgedessen ist dieselbe hoch belastet und muß entsprechend stabil gelagert und ausgebildet sein.Such an articulated arm awning is known from EP-A-0 084 076. There, a threaded rod is adjustable via a worm gear driven by a shaft. The total tensile load on the articulated arms depends on the threaded rod. As a result, it is heavily loaded and must be stored and trained accordingly stable.

Die DE-A-2 256 274 (vgl. FR-A-2 161 230) beschreibt einen Gelenkarm, dessen Lagerbock zur Einstellung der Neigung der Markise in einem Halter verdrehbar ist. Die Verstellung des Lagerbocks erfolgt durch eine Spindelmutter, die in eine Gewindestange eingreift. Die Gewindestange ist in einer Gabel des Halters geführt und wird durch das Gewicht der Markise unter Spannung gehalten. Eine Rückschlagsicherung ist hier nicht vorhanden.DE-A-2 256 274 (cf. FR-A-2 161 230) describes an articulated arm, the bearing block of which can be rotated in a holder to adjust the inclination of the awning. The bearing block is adjusted by a spindle nut which engages in a threaded rod. The threaded rod is guided in a fork of the holder and is held under tension by the weight of the awning. There is no setback protection here.

Die DE-A-2 834 486 beschreibt ein Armlager, dessen Tragbock ein Schneckenrad aufnimmt, das mit einer einer Schnecke auf einer Stellwelle innerhalb des Tragrohrs in Eingriff ist. Das Schneckenrad verstellt spindelartig eine Koppelstange, die in einen Kulissenschlitz des Lagerbocks eingreift. Hier ist eine führungsstabile Lagerung des Schneckenrades erforderlich.DE-A-2 834 486 describes an arm bearing whose support bracket receives a worm wheel which engages with a worm on an actuating shaft within the support tube. The worm wheel adjusts a coupling rod like a spindle, which engages in a link slot of the bearing block. The worm wheel must be supported in a stable manner.

Aufgabe der Erfindung ist die Bereitstellung eines Armlagers, das mit einem jederzeit verfügbaren Werkzeug in einfacher Weise einstellbar ist und eine hohe Stabilität, insbesondere Verwindungssteifigkeit und Rückschlagsicherheit hat.The object of the invention is to provide an arm support which can be adjusted in a simple manner using a tool which is available at all times and which has high stability, in particular torsional rigidity and kickback protection.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß die beiden oben am Tragrohr aufliegenden parallelen Stege an den Enden durch einen Quersteg verbunden sind, daß die Gewindehülse innerhalb eines Durchgangs oder eine Rinne im Quersteg drehbar angeordnet ist, wobei die Gewindehülse mit einem Mehrkantansatz oder Anlageflansch, der ein Drehen der Gewindehülse ermöglicht, an der Außenseite des Quersteges anliegt, und daß eine Feder einen Anlageflansch der Gewindehülse gegen die Aufnahme spannt.This object is achieved according to the invention in that the two parallel webs lying on top of the support tube are connected at the ends by a crossbar, that the threaded sleeve is rotatably arranged within a passage or a groove in the crossbar, the threaded sleeve having a polygonal attachment or contact flange , which allows the threaded sleeve to rotate, rests on the outside of the crossbar, and in that a spring clamps a contact flange of the threaded sleeve against the receptacle.

Das Armlager nach der Erfindung unterscheidet sich dadurch vom Stand der Technik, als die Neigung durch Drehen eines Gewindebolzens in einer Gewindehülse einstellbar ist. Diese Drehung kann mit einem schlüsselartigen Werkzeug erfolgen. Die schraubende Anordnung des Gewindebolzens in der Gewindehülse ist selbsthemmend, so daß eine Sicherung der Einstellung nicht erforderlich ist. Die Neigung läßt sich jederzeit verstellen. Dabei ist die Neigung immer, auch während der Verstellung, eindeutig festgelegt. Das jeweilige Armlager ist in seiner Einstellung gesichert. Es ist ohne Schwierigkeiten ein Schwenkbereich bis zu 45° Neigung gegenüber der Horizontalen möglich. Das Armlager hat eine sehr stabile Kontruktion. Es besteht aus einer gabelförmigen, winkligen Anordnung. Der Lagerbock ist zwischen Augen des Tragbocks aufgenommen und dadurch auch bei starken Krafteinwirkungen, insbesondere Querkräften verkantungssicher geführt. Der Gewindebolzen liegt zwischen den Stegen in einer Rinne oder einem Schlitz. Durch die gegenseitige Führung der Teile und die kräftigen Zapfen ergibt sich eine hohe Stabilität des Armlagers und insbesondere eine hohe Verwindungssteifigkeit, so daß das Armlager allen betriebsmäßigen Belastungen standhalten kann.The arm bearing according to the invention differs from the prior art in that the inclination can be adjusted by turning a threaded bolt in a threaded sleeve. This rotation can be done with a key-like tool. The screwing arrangement of the threaded bolt in the threaded sleeve is self-locking, so that it is not necessary to secure the setting. The inclination can be adjusted at any time. The inclination is always clearly defined, even during the adjustment. The setting of the respective arm bearing is secured. A swivel range of up to 45 ° to the horizontal is possible without difficulty. The arm bearing has a very stable construction. It consists of a forked, angular arrangement. The pedestal is received between the eyes of the trestle and is therefore protected against canting even when subjected to strong forces, in particular transverse forces. The threaded bolt lies between the webs in a channel or slot. The mutual guidance of the parts and the strong pins result in a high stability of the arm bearing and in particular a high torsional stiffness, so that the arm bearing can withstand all operational loads.

Eine stabile Ausbildung und Erhöhung der Verwindungssteifigkeit erhält man dadurch, daß zur gelenkigen Aufnahme des Gewindebolzens ein Zapfen in Augen des Lagerbocks sitzt und daß sich der Gewindebolzen etwa in der Mitte zwischen den beiden Stegen des Schenkels erstreckt.A stable design and increase in the torsional rigidity is obtained in that a pin sits in the eyes of the bearing block for the articulated reception of the threaded bolt and that the threaded bolt extends approximately in the middle between the two webs of the leg.

Eine Art der Anordnung des Gewindebolzens ist dadurch gekennzeichnet, daß der Zapfen ein Auge des Gewindebolzens aufnimmt.One type of arrangement of the threaded bolt is characterized in that the pin receives an eye of the threaded bolt.

Eine andere Anordnung mit einfacher Montierbarkeit erhält man dadurch, daß der Zapfen einen Querdurchgang aufweist und daß der Gewindebolzen mit einem Kopfbund an dem Zapfen anliegt. Hierbei verhindert der Gewindebolzen, daß der Zapfen aus seinem Durchgang herausgleitet. Es ist also keine besondere Sicherung des Zapfens erforderlich.Another arrangement with simple assembly is obtained in that the pin has a transverse passage and that the threaded bolt rests with a head collar on the pin. The threaded bolt prevents the pin from sliding out of its passage. No special securing of the pin is therefore required.

Die Montierbarkeit wird dadurch erleichtert, daß der Lagerbock senkrecht zum Durchgang für den Zapfen einen Durchgang für den Kopf des Gewindebolzens und außerdem eine Ausnehmung im Anschluß an den Durchgang zur Verschwenkung des Kopfes aufweist.The assembly is facilitated in that the bearing block perpendicular to the passage for the pin has a passage for the head of the threaded bolt and also has a recess following the passage for pivoting the head.

Zur zusätzlichen Sicherung gegen Verstellung sieht die Erfindung vor, daß die als Tellerfeder ausgebildete Feder zwischen einem Mebrkantansatz der Gewindehülse und dem Quersteg angeordnet ist.To provide additional security against displacement, the invention provides that the spring, which is designed as a plate spring, is arranged between a mezzanine neck of the threaded sleeve and the crossbar.

Die Sicherung der Verstellvorrictung gegen ungewollte Verstellung oder gegen ein Herausspringen aus den Führungen wird dadurch verbessert, daß die Aufnahme des Quersteges als halbzylindrische Rinne ausgebildet ist, daß die Gewindehülse an beiden Enden eines Rohrteiles Anlageflansche aufweist, die an den Stirnflächen der Rinne anliegen, und daß in dem Quersteg ein Führungsdurchgang für den Gewindebolzen vorgesehen ist. Auch bei stoßartigen Bealstungen der Markise durch Windkräfte oder dgl. kann sich das Armlager nicht ungewollt verstellen oder ausschlagen. Beschädigungen der Markise sind daher ausgeschlossen.Securing the Verstellvorrictung against unwanted adjustment or against jumping out of the guides is improved in that the recording of the crossbar is designed as a semi-cylindrical groove, that the threaded sleeve at both ends of a tubular part has contact flanges that abut the end faces of the channel, and that a guide passage for the threaded bolt is provided in the crosspiece. Even in the event of sudden loads on the awning caused by wind forces or the like, the arm bearing cannot inadvertently adjust or deflect. Damage to the awning is therefore excluded.

Die Festspannung des Armlagers an dem Vierkanttragrohr wird dadurch erreicht, daß an den Enden der Stege Durchgänge für Verschraubungen vorgesehen sind, die in den gegenüberliegenden Schenkel eingreifen und den Tragbock am Vierkanttragrohr festspannen.The fixed tension of the arm bearing on the square support tube is achieved in that the ends of the webs are provided for screw connections, which engage in the opposite leg and tighten the trestle on the square support tube.

The leg 13 comprises two webs 14 which run parallel to one another and which are connected to one another at the ends by a cross web 15. As a result, a groove 17 or a slot is formed between the webs 14. A passage 16 is provided in the crosspiece 15 and is aligned with the channel 17 between the webs 14. Two eyes 18 protrude from the central web 12 and also form guide walls. At the ends of the webs 14, passages 19 are formed which are aligned with passages 20 in the leg 11. These passages serve to receive screw connections 21 or other tensioning devices, which are indicated schematically in FIG. 2 and serve to firmly clamp the support bracket 3 on the square support tube 1.

Die Augen 18 nehmen einen Tragzapfen 22 auf, auf dem der Lagerbock 4 schwenkbar sitzt. Der Lagerbock 4 ist zwischen den Führungswänden der Augen 18 und auf dem stabilen Tragzapfen 22 verkantungssicher geführt. Der Lagerbock 4 ist ein im wesentlichen rechtkantiger Teil und besitzt am Stirnende einen Durchgang 23 zur Aufnahme eines nichtdargestellten Lagerzapfens für einen Schwenkarm 6. Am oberen Ende, dem Tragzapfen 22 gegenüberliegend, sind einander gegenüberstehend zwei Augen 24 angeformt, die einen Zapfen 25 aufnehmen.The eyes 18 receive a support pin 22 on which the bearing block 4 is pivotably seated. The bearing block 4 is guided between the guide walls of the eyes 18 and on the stable support pin 22 so as to prevent jamming. The bearing block 4 is a substantially right-angled part and has at the front end a passage 23 for receiving a bearing pin (not shown) for a swivel arm 6. At the upper end, opposite the supporting pin 22, two eyes 24 are formed opposite one another, which receive a pin 25.

Auf dem Zapfen 25 sitzt schwenkbar ein Auge 26 eines Gewindebolzens 27. Der Gewindebolzen 27 erstreckt sich etwa parallel zu den Stegen 14 innerhalb des Schlitzes oder der Rinne 17. Der Gewindebolzen 27 greift mit einem Gewindeabschnitt 32 in eine Gewindehülse 28 ein, die sich innerhalb des Durchgangs 16 befindet. An einem Ende besitzt die Gewindehülse 28 einen Mehrkantansatz 29, der ein Drehen der Gewindehülse 28 ermöglicht. Zwischen einer Stirnfläche des Mehrkantansatzes 29 und der Stirnfläche des Quersteges 15 befindet sich eine Tellerfeder 31, die eine zusätzliche Spannkraft und Reibungskraft erzeugt. Am anderen Ende ist die Gewindehülse durch einen Seegerring 30 in axialer Richtung gesichert. Der Außendurchmesser der Gewindehülse 28 ist kleiner als der Innendurchmesser des Durchgangs 16, damit sich die Gewindehülse 28 innerhalb des Durchgangs bewegen und verstellen kann. Da die Gewindehülse 28 in beiden Bewegungsrichtungen gegen eine Verschiebung gesichert ist, sind dadurch die Gelenkarme der Markise stabil gehalten, so daß die Markise nicht hochschlagen kann.An eye 26 of a threaded bolt 27 is pivotably seated on the pin 25. The threaded bolt 27 extends approximately parallel to the webs 14 within the slot or the channel 17. The threaded bolt 27 engages with a threaded portion 32 in a threaded sleeve 28 which is located within the Passage 16 is located. At one end, the threaded sleeve 28 has a polygonal projection 29, which enables the threaded sleeve 28 to be rotated. Between an end face of the polygonal extension 29 and the end face of the cross bar 15 there is a plate spring 31 which generates an additional clamping force and frictional force. At the other end, the threaded sleeve is secured in the axial direction by a circlip 30. The outer diameter of the threaded sleeve 28 is smaller than the inner diameter of the passage 16 so that the threaded sleeve 28 can move and adjust within the passage. Since the threaded sleeve 28 is secured against displacement in both directions of movement, the articulated arms of the awning are thereby held stable, so that the awning cannot swing up.

Durch Drehen des Mehrkantansatzes 29 wird der Gewindebolzen 27 innerhalb der Gewindehülse 28 schraubend verschoben. Dementsprechend wird der Lagerbock 4 um den Tragzapfen 22 verschwenkt. Die Reibung in den Bauelementen und zusätzliche durch die Tellerfeder ist so groß, daß eine unbeabsichtigte Verstellung nicht möglich ist. Es ist infolgedessen auch keine formschlüssige Sicherung der Gewindehülse 28 gegen Verdrehung erforderlich. Durch Drehen an dem Mehrkantansatz 29 läßt sich der Lagerbock 4 in sehr einfacher Weise verstellen. Dementsprechend einfach läßt sich die Neigung der Gelenkarme und damit die Neigung der Markise verstellen. Es hat sich gezeigt, daß der durch das Armlager nach der Erfindung erzielbare Schwenkbereich von über 45° gegenüber der Horizontalen in der Praxis völlig ausreicht. Für den Benutzer ist eine Verstellung der Neigung mit einem Maulschlüssel möglich. Es ist nicht erforderlich, irgendwelche Befestigungselemente zu lösen. Die Neigung ist in jedem Ausfahrzustand der Markise verstellbar und in jedem Zustand eindeutig festgelegt, so daß sich die Markise nicht ungewollt in ihrer Neigung verstellen kann. Der Gewindebolzen 27 ist zwischen den Stegen 14 gegen schädliche Einwirkungen geschützt. Der Lagerbock ist in seinem ganzen Verschwenkbereich durch die Führungswände der Augen 18 seitlich geführt und damit gegen Verkantungen gesichert. Eine unzulässige Belastung des Tragzapfens 22 ist vermieden. Durch die stabile Konstruktion und die gegenseitige Führung der Elemente ist eine hohe Verwindungssteifigkeit gewährleistet.By turning the polygonal projection 29, the threaded bolt 27 is screwed inside the threaded sleeve 28. Accordingly, the bearing block 4 is pivoted about the support pin 22. The friction in the components and additional due to the plate spring is so great that an unintentional adjustment is not possible. As a result, there is also no need for a form-fitting securing of the threaded sleeve 28 against rotation. The bearing block 4 can be adjusted in a very simple manner by turning the polygonal projection 29. The inclination of the articulated arms and thus the inclination of the awning can be adjusted accordingly. It has been shown that the pivoting range of over 45 ° with respect to the horizontal that can be achieved by the arm bearing according to the invention is completely sufficient in practice. The user can adjust the inclination with an open-ended wrench. There is no need to loosen any fasteners. The inclination can be adjusted in every extension state of the awning and is clearly defined in every state, so that the inclination of the awning cannot be changed unintentionally. The threaded bolt 27 is protected between the webs 14 against harmful effects. The bearing block is guided laterally in its entire pivoting area through the guide walls of the eyes 18 and is thus secured against tilting. An inadmissible load on the trunnion 22 is avoided. The stable construction and the mutual guidance of the elements ensure high torsional rigidity.

Die Fig. 4 und 5 zeigen eine abgewandelte Ausführungform des Armlagers. Gleiche Bauteile sind mit gleichen Bezugsziffern versehen.4 and 5 show a modified embodiment of the arm bearing. The same components are provided with the same reference numbers.

Der Lagerbock 4 besitzt im Kopfteil 51 einen Durchgang 52 für den Zapfen 65. Der Zapfen 65 hat seinerseits einen Querdurchgang 66, der den Gewindebolzen 67 aufnimmt. Der Gewindebolzen 67 hat einen Kopf 70"der mit einem Kopfbund 69 an dem Zapfen 65 anliegt. Im Kopfteil 61 ist ein quer zu dem Zapfen 69 ausgerichteter Durchgang 71 mit den Querabmessungen des Kopfes 70 vorgesehen, an den sich eine Ausnehmung 72 anschließt. Man erkennt deutlich aus Fig. 2, daß der Gewindebolzen 67 durch Einführen in den Durchgang 71 und Verschwenken des Kopfes in die Ausnehmung 72 innerhalb des Lagerbocks 4 montierbar ist. Der Kopfteil 51 besitzt weitere Ausnehmungen, die dann ein Verschwenken des Gewindebolzens 67 in die dargestellte Montagestellung ermöglichen.The bearing block 4 has a passage 52 in the head part 51 for the pin 65. The pin 65 in turn has a transverse passage 66 which receives the threaded bolt 67. The threaded bolt 67 has a head 70 ″ which rests with a head collar 69 on the pin 65. In the head part 61 there is a passage 71, which is oriented transversely to the pin 69 and has the transverse dimensions of the head 70 and which is followed by a recess 72 2 that the threaded bolt 67 can be mounted by inserting it into the passage 71 and pivoting the head into the recess 72 within the bearing block 4. The head part 51 has further recesses which then enable the threaded bolt 67 to be pivoted into the mounting position shown.

Der Gewindebolzen 67 ist in einem Führungsdurchgang 77 des Quersteges 15 geführt. Die Aufnahme in den Quersteg 15 ist in diesem Fall als halbzylindrische Rinne 56 ausgebildet. Die Gewindehülse 73 umfaßt einen mittleren Rohrteil 74, der im wesentlichen den Querschnitt der Rinne 56 ausfüllt und jeweils an den Enden Anlageflansche 75 und 76, die an den Stirnflächen der Rinne 56 anliegen. Dadurch ist die Gewindehülse 73 gegen ein axiales Verschieben in beiden Richtungen gesichert. Der Anlageflansch 76 ist gleichzeitig ein Mehrkantansatz zur Verstellung der Gewindehülse 73. Eine Schraubendruckfeder 78 spannt den Anlageflansch 75 gegen die betreffende Stirnfläche des Quersteges 15 vor, um dadurch eine höhere Reibung und einen Schutz gegen ungewolltes Verstellen bereitzustellen.The threaded bolt 67 is guided in a guide passage 77 of the cross bar 15. The inclusion in the crosspiece 15 is in this case designed as a semi-cylindrical groove 56. The threaded sleeve 73 comprises a central tube part 74, which essentially fills the cross section of the channel 56 and at the ends of contact flanges 75 and 76, which abut the end faces of the channel 56. As a result, the threaded sleeve 73 is secured against axial displacement in both directions. The contact flange 76 is at the same time a polygonal approach for adjusting the threaded sleeve 73. A helical compression spring 78 prestresses the contact flange 75 against the relevant end face of the crossbar 15, in order to thereby provide greater friction and protection against unwanted adjustment.

Diese Ausführungsform der Erfindung erlaubt eine gleiche Verstellung des Lagerbocks 4, wie die zuvor beschriebene Ausführungsform. Die Verstellung erfolgt durch Drehen der Gewindehülse 73 und damit axiales Verschieben des Gewindebolzens 67. Die Gewindehülse 73 ist innerhalb der Rinne 56 und an den Stirnwänden derselben formschlüssig geführt und nach beiden Verstellrichtungen des Gewindebolzens 67 abgestützt. Ein Herausspringen der Gewindehülse 73 aus der Rinne 56 ist nicht möglich, weil dieses durch den Führungsdurchgang 77 und die Rührungswand 79 des Schenkels 13 verhindert wird. So wird der Gewindebolzen 67 mit der Gewindehülse 73 immer in Eingriff in der Rinne 56 gehalten. Der Lagerbock 4 und damit der jeweilige Ausfahrarm der Markise sind somit sehr stabil gehalten. Die Markise ist damit gegen jede ungewollte Verschiebung, beispielsweise unter Windbelastung gesichert.This embodiment of the invention allows the same adjustment of the bearing block 4 as the embodiment described above. The adjustment is carried out by rotating the threaded sleeve 73 and thus axially displacing the threaded bolt 67. The threaded sleeve 73 is guided in a form-fitting manner within the groove 56 and on the end walls thereof and is supported in both directions of adjustment of the threaded bolt 67. A jumping out of the threaded sleeve 73 from the groove 56 is not possible because this is prevented by the guide passage 77 and the stirring wall 79 of the leg 13. Thus, the threaded bolt 67 with the threaded sleeve 73 is always held in engagement in the groove 56. The bearing block 4 and thus the respective extension arm of the awning are kept very stable. The awning is thus secured against any unwanted movement, for example under wind loads.
