Abstract

The Florentine blind with articulated arms according to the invention takes into account the mechanical loading which increases with an increasing blind width and extension length. Whilst retaining proven arrangements as a roll-up safeguard, the articulated parts have an angular position relative to one another which can easily be set by a mechanic. A threaded bolt (27) is proposed which has two threaded portions (28, 29) running in opposite directions which are provided, on the one hand, in the holding arm (12) and, on the other hand, in a part of a stop dish (6) mounted in an articulated manner relative thereto. The threaded bolt (27) passes through a tilting joint (22) which can be pivoted between said two parts, such that the forces to be absorbed have only a very small spacing from the pivot axis (13, 10). This considerably reduces the torque to be absorbed. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Gelenkarmmarkise gemäß der im Patentanspruch 1 näher bezeichneten Art.The invention relates to an articulated arm awning according to the type specified in claim 1.

Derartige Gelenkarmmarkisen sind nach der DE-OS 28 53 286 bekannter Stand der Technik. In eingezogenem Zustand wird die Markise dabei in einem an der Wand oder dergleichen befestigten Kasten aufgenommen, der nach vorne zu offen ist oder leicht zu öffnen ist, um die Markise ausfahren zu lassen. Für den Zweck wird zunächst an den Gelenkarmlagern der Neigungswinkel eingestellt, um den die Markise zur Hauswand geneigt sein soll. Dies geschieht mit einem einstellbaren Schraubbolzen, der an einem Haltearm angelenkt ist und verschwenkbar sowie unverdrehbar ist. Eine an sein freies Ende aufgeschraubte Anschlagmutter wird auf den vorgesehenen Wert eingestellt, so daß das Kippgelenk entsprechend dem vorgesehenen Neigungswinkel an der Schraubmutter zur Anlage kommen kann. Zugleich bildet die Einstellschraube mit Anschlagmutter einen Bestandteil einer Hochschlagsicherung, die ein unbeabsichtigtes Hochschlagen der ausgefahrenen Markise verhindern soll. Diesem Zweck dient beim Stand der Technik ein zusätzlicher Sperriegel, der sich zwischen das Kippgelenk und die Anschlagmutter schiebt, wenn das Ausfahren der Markise, genauer gesagt die Entfaltung der Gelenkarme, ein vorgegebenes Maß überschreitet. Der Sperriegel steht hierfür mit dem Kippgelenk in Verbindung und wird dann von diesem in eine Sperrstellung gesteuert. Für die Verbindung ist ein Stab vorgesehen, der hohen Belastungen auf Zug und Druck entsprechen muß und bei Durchbiegungen, zum Beispiel bei hohen Belastungen, leicht klemmen kann. Hinzu kommt, daß die Anschlagmutter nur eine sehr geringe Anschlagfläche aufweist, so daß auch durch den normalen Betrieb Schäden bei größeren Anlagen nicht vermeidbar sind.Such articulated arm awnings are known according to DE-OS 28 53 286 prior art. In the retracted state, the awning is received in a box attached to the wall or the like, which is too open towards the front or is easy to open in order to allow the awning to extend. For the purpose, the angle of inclination by which the awning should be inclined to the house wall is first set on the articulated arm bearings. This is done with an adjustable screw bolt, which is articulated on a holding arm and is pivotable and non-rotatable. A stop nut screwed onto its free end is set to the intended value so that the tilt joint can come into contact with the screw nut in accordance with the intended inclination angle. At the same time, the adjusting screw with the stop nut forms part of an anti-roll-up device that is intended to prevent the awning from being raised unintentionally. In the prior art, this purpose is served by an additional locking bolt which slides between the tilt joint and the stop nut when the extension of the awning, more precisely the unfolding of the articulated arms, exceeds a predetermined dimension. For this purpose, the locking bolt is connected to the tilt joint and is then controlled into a locking position by the latter. A rod is provided for the connection, which must correspond to high loads under tension and pressure and can easily jam in the event of deflections, for example under high loads. In addition, the stop nut has only a very small stop surface, so that damage cannot be avoided in larger systems even during normal operation.

Zur Behebung dieser Nachteile sieht die DE-PS 34 24 111 eine schwerere Konstruktion vor, bei der die Anschlagmittel als eine Anschlagschale ausgeführt sind, die der Kippbegrenzung dient, und die im ausgefalteten Zustand des Gelenkarms von den Gabelteilen des Gabel- Kopfes übergriffen ist. Hierdurch entsteht eine Verriegelung, sobald sich die Gelenkarme in Richtung ihrer Neigungslage ausfalten, in welcher Stellung ein Hochschlagen wirkungsvoll verhindert wird. Die Voreinstellung des Neigungswinkels macht in diesem Falle eine Einstellung der Anschlagschale erforderlich, für welchen Zweck sie mit zwei Stellschrauben versehen ist, die eine Bogenführung des Haltearms durchsetzen und durch Festschraubung einen Klemmsitz am Haltearm annehmen. Zusätzlich findet noch eine Feinjustierung Verwendung, um die Querkräfte der Markisenbewegung abzufangen. Die Klemmschrauben und die Mittel zur Feinjustierung eignen sich jedoch weniger für größere, mehr als sechs Meter breite Markisen nur bedingt. Hinzu kommt, daß die Einstellung des Neigungswinkels zwei Mechaniker erforderlich macht, von denen der eine die Einstellung vornehmen kann, indem er die Schraubbolzen betätigt, während der andere die Markise so lange hochhält, bis die Schraubmechanik wirksam wird.To remedy these disadvantages, DE-PS 34 24 111 provides a heavier construction, in which the lifting means are designed as a stop shell, which serves to limit the tilt, and which is overlapped by the fork parts of the fork head when the articulated arm is folded out. This creates a lock as soon as the articulated arms unfold in the direction of their inclination, in which position an upward stroke is effectively prevented. In this case, the presetting of the angle of inclination makes it necessary to adjust the stop shell, for which purpose it is provided with two set screws which pass through an arched guide of the holding arm and, due to the screw connection, assume a clamp fit on the holding arm. In addition, a fine adjustment is used to absorb the transverse forces of the awning movement. However, the clamping screws and the means for fine adjustment are less suitable for larger awnings that are more than six meters wide. In addition, the adjustment of the angle of inclination requires two mechanics, one of whom can make the adjustment by operating the screw bolts, while the other holds the awning up until the screwing mechanism takes effect.

Vom einleitend beschriebenen Stand der Technik ausgehend liegt der Erfindung die Aufgabenstellung zugrunde, die bei der Markisenbenutzung entstehenden Kräfte durch eine verbesserte Konstruktion wirkungsvoller aufnehmen zu können. Die Hochschlagsicherung soll dabei ebenfalls Bestandteil der Gelenkteile bleiben.Starting from the state of the art described in the introduction, the invention is based on the object of being able to absorb the forces arising when using the awning more effectively by means of an improved construction. The high-impact protection should also remain part of the joint parts.

Die Erfindung löst diese Aufgabenstellung durch die in den Patentansprüchen gemachten Vorschläge.The invention solves this problem by the suggestions made in the claims.

Somit werden die Anschlagmittel ihrerseits zu einem Bauteil weiterentwickelt, dessen Bewegung durch die Steuerung seines Gelenkes vorgegeben ist. Der Bewegungsbereich wird durch mehr oder weniger starkes Einschrauben oder Ausschrauben des miteinander entgegengesetzten Gewindeabschnitten versehenen Schraubbolzens vorgegeben. Die nach dem Stand der Technik vorgesehene Verwendung eines Sperrriegels mit einer Verbindungsstange zum Kippgelenk hin ist bei der erfindungsgemäßen Ausführungsform, bei welcher die Anschlagmittel parallel zur Kippgelenkachse ein Lager haben müssen, so daß die Anschlagmittel schon aus diesem Grunde massiver ausfallen müssen.In this way, the slings are themselves developed into a component, the movement of which is predetermined by the control of its joint. The range of motion is predetermined by more or less screwing in or unscrewing the screw bolt provided with opposite threaded sections. The use according to the prior art of a locking bolt with a connecting rod to the tilt joint is in the embodiment according to the invention in which the stop means must have a bearing parallel to the tilt joint axis, so that the stop means must be more solid for this reason alone.

Bei einer Belastung werden die auftretenden Kräfte wirkungsvoll abgefangen, wobei der eingeschraubte Schraubbolzen eine unveränderliche Lage des Anschlagmittels in Bezug auf den Haltearm gewährleistet.In the event of a load, the forces which occur are effectively absorbed, the screwed-in screw bolt ensuring an unchangeable position of the lifting means in relation to the holding arm.

In der neuen Ausführungsform werden die Anschlagmittel als Anschlagschalen ausgeführt, an denen sich Gelenkhülsen der Gabelköpfe der Gelenkarme abstützen. Bei dieser als solche nach der DE-PS 34 24 111 bekannten Ausbildung der Anschlagmittel übergreifen die Schenkel der Gabelköpfe die Anschlagschalen, während zwischen der Gelenkhülse und dem Gabelkopf ein Spalt für die Eindringung der Anschlagschale bei zunehmender Entfaltung der Gelenkarme besteht. Die der Kippbegrenzung dienende Anschlagschale bildet somit eine im ausgefalteten Zustand wirksame Verriegelung, in welcher Stellung ein Hochschlagen der Markise wirkungsvoll verhindert ist. Die genannten Teile sind in Bezug zueinander ausschließlich verschwenkbar, so daß die konstruktiven Schwierigkeiten bei Verschiebebewegungen behoben werden.In the new embodiment, the sling means are designed as stop shells, on which articulated sleeves of the fork heads of the articulated arms are supported. In this known as such according to DE-PS 34 24 111 design of the sling means overlap the legs of the clevises the stop shells, while there is a gap between the joint sleeve and the clevis for the penetration of the stop shell with increasing unfolding of the articulated arms. The stop shell which serves to limit the tilt thus forms an effective locking when unfolded, in which position the awning is effectively prevented from being raised. The parts mentioned can only be pivoted in relation to one another, so that the constructional difficulties associated with displacement movements are eliminated.

Die vorstehend dargestellte Neuerung gestattet die sichere Betriebsweise bei Markisen auch mit mehr als 6 m Breite, wobei die Ausfahrlänge beispielsweise auch 3,50 m betragen kann. Durch die neu vorgeschlagenen Einstellmittel in Form der entgegengesetzte Gewinde aufweisenden Verschraubung entfallen gleichfalls die sonst durch Querkräfte auftretenden Verspannungen, denen die Feinjustierung der bekannten Ausführungsform nicht mehr Rechnung tragen konnte. Überdies gestattet es die Erfindung, die Verstellkräfte in dichter Annäherung an die Lagerung zu übertragen, so daß sich entsprechend geringere Momente ergeben. Vielmehr wird die Kraft der Verstellbewegungen durch den quer zur Tuchrolle verlaufenden Schraubbolzen eingeleitet, für den zwei Wirkungslinien bestehen, von denen die eine in der Längsrichtung des Schraubbolzens wirkt, wohingegen die andere durch eine den Schraubbolzen radial beaufschlagende Feststellschraube bedingt ist. Die beiden Achsen für die Gewindebüchsen des Schraubbolzens verlaufen mit seitlichem Abstand parallel zueinander. Eine Betätigung des Schraubbolzens führt dazu, daß sich die Achsen nähern oder voneinander auf Abstand gehen.The innovation presented above allows the safe operation of awnings with a width of more than 6 m, the extension length at for example, can also be 3.50 m. The newly proposed adjusting means in the form of the screw connection having the opposite thread also eliminates the tensions that otherwise occur due to transverse forces, which the fine adjustment of the known embodiment could no longer take into account. In addition, the invention allows the adjusting forces to be transmitted in closer proximity to the bearing, so that correspondingly lower moments result. Rather, the force of the adjustment movements is introduced by the screw bolt running transversely to the cloth roll, for which there are two lines of action, one of which acts in the longitudinal direction of the screw bolt, whereas the other is caused by a locking screw acting radially on the screw bolt. The two axes for the threaded bushes of the screw bolt run parallel to each other with a lateral distance. Actuation of the bolt causes the axes to approach or move apart.

Es ist mittels des vorgeschlagenen Schraubbolzens ohne Schwierigkeiten möglich, Einstellungen durch einen einzelnen Mechaniker vornehmen zu lassen, der dann lediglich einen, zweckmäßig durch Innensechskant verstellbaren Schraubbolzen einzustellen hat. Die bislang üblich gewesene, kraftschlüssige Verbindung durch Festklemmung von Schraubbolzen wird erfindungsgemäß durch den Formschluß des Schraubbolzens verbessert. Die auffangbaren Kräfte lassen sich durch die Neuentwicklung mehr als verdoppeln.By means of the proposed screw bolt it is possible without difficulty to have adjustments made by a single mechanic, who then only has to set a screw bolt which is expediently adjustable by means of a hexagon socket. The previously used, non-positive connection by clamping screw bolts is improved according to the invention by the positive locking of the screw bolt. The forces that can be absorbed can be more than doubled through the new development.

Die für den Schraubbolzen vorgesehenen Gewindebüchsen sind insbesondere Zylinderscheiben in zur Kippachse parallelen Bohrungen des Haltearmes und der Anschlagschale verschwenkbaren Lagern, wobei die Gewinde senkrecht zu ihren Achsen in sie eingeschnitten sind.The threaded bushings provided for the screw bolts are, in particular, cylindrical disks in bores of the holding arm and the stop shell which can be pivoted parallel to the tilting axis, the threads being cut into them perpendicular to their axes.

Den Schraubbolzen, der im Interesse niedriger Momente relativ dicht zur Kippachse verlaufen soll, beeinträchtigt die Funktion des Kippgelenkes nicht, zumal er nach einem weiterernMerkmal der Erfindung den Block des Kippgelenkes in einer dafür geeigneten Öffnung zwischen Haltearm und Anschlagmittel durchsetzt, so daß das Kippgelenk zwischen diesen beiden Teilen frei verschwenkbar bleibt.The bolt, which should be relatively close to the tilt axis in the interest of low moments, does not impair the function of the tilt joint, especially since, according to a further feature of the invention, it passes through the block of the tilt joint in a suitable opening between the holding arm and the lifting means, so that the tilt joint between them both parts remains freely pivotable.

Zur weiteren Veranschaulichung der Erfindung wird auf die Zeichnungen Bezug genommen, die ein Ausführungsbeispiel schematisch veranschaulichen.To further illustrate the invention, reference is made to the drawings which schematically illustrate an exemplary embodiment.

Darin zeigen:

  • Figur 1 einen Querschnitt durch den Markisenkasten,
  • Figur 2 das Kippgelenk mit dem Gelenkarmende,
  • Figur 3 eine Draufsicht auf die Anschlagschale und
  • Figur 4 eine seitliche Darstellung der Anschlagschale.
In it show:
  • FIG. 1 shows a cross section through the awning box,
  • FIG. 2 the tilt joint with the end of the articulated arm,
  • Figure 3 is a plan view of the stop shell and
  • Figure 4 is a side view of the stop shell.

Das Markisengehäuse nach Figur 1 sieht an der linken Seite eine Befestigung an einer Wand vor, so daß dessen rechte Seite zum Ausfahren der Markise offen bleibt. Im oberen Teil des Markisenkastens ist die hier nicht näher dargestellte Tuchrolle untergebracht, wohingegen der untere Teil des Markisenkastens den Haltearm 12 trägt. Letzterer schließt vorne mit zwei Bohrungen 14 und 15 für die Aufnahme der Gewindebüchse 24 sowie für die Lagerung der Anschlagschale 6 mit der Schwenkachse 13.The awning housing according to FIG. 1 provides for attachment to a wall on the left side, so that its right side remains open for extending the awning. In the upper part of the awning box the cloth roll, not shown here, is housed, whereas the lower part of the awning box carries the holding arm 12. The latter closes at the front with two bores 14 and 15 for receiving the threaded bush 24 and for mounting the stop shell 6 with the pivot axis 13.

Der Gewindebüchse 24 entspricht eine Gewindebüchse 25 in der Anschlagschale 6, von denen beide entgegengesetzt gerichtete Gewindebohrungen aufweisen. In diese greifen die Gewindeabschnitte 28 und 29 des Schraubbolzens 27 ein, so daß bei dessen Betätigung, beispielsweise mittels eines Innensechskantes, der Verschwenkabstand zwischen Haltearm 12 und Anschlagschale 6 verringert wird. In die Anschlagschale 6 legt sich die Gelenkhülse 3 der Schwenkachse 16 in der Endstellung der ausgefalteten Gelenkarme 26 anschlagend ein. Die Gelenkhülse 3 ist dabei Bestandteil des Kippgelenkes 22, wie es in Figur 2 erkennbar ist. Dabei besteht die Kippachse 10, um welche das Kippgelenk 22 kippen kann, und die koaxial zur Schwenkachse 13 der Anschlagschale 6 verläuft. Der Gewindeabschnitt 29 des Schraubbolzens 27 unterliegt noch der Einwirkung einer Feststellschraube 17, die in die Gewindebüchse 25 in axialer Richtung derselben einschraubbar ist.The threaded bushing 24 corresponds to a threaded bushing 25 in the stop shell 6, both of which have oppositely directed threaded bores. The threaded sections 28 and 29 of the screw bolt 27 engage in this, so that when it is actuated, for example by means of an internal hexagon, the pivoting distance between the holding arm 12 and the stop shell 6 is reduced. The joint sleeve 3 of the pivot axis 16 lies in the end position of the folded-out articulated arms 26 in the stop shell 6. The joint sleeve 3 is part of the tilt joint 22, as can be seen in Figure 2. There is the tilt axis 10, about which the tilt joint 22 can tilt, and which runs coaxially with the pivot axis 13 of the stop shell 6. The threaded portion 29 of the screw bolt 27 is still subject to the action of a locking screw 17 which can be screwed into the threaded bushing 25 in the axial direction thereof.

Das Kippgelenk 22 ist in der bereits beschriebenen Weise frei zwischen Haltearm 12 und Anschlagschale 6 verschwenkbar. Dabei ist es vom Schraubbolzen 27 durchsetzt, zu welchem Zweck die in Figur 2 erkennbare, längliche Öffnung 30 besteht. Diese Form der Öffnung 30 gestattet es, daß der Schraubbolzen 27 die Verschwenkstellungen einnimmt, die sich aus zu einem mehr oder weniger tiefen Eingreifen in die Gewindebüchsen 24 und 25 ergeben.The tilt joint 22 can be pivoted freely between the holding arm 12 and the stop shell 6 in the manner already described. It is penetrated by the screw bolt 27, for which purpose the elongated opening 30 shown in FIG. 2 exists. This shape of the opening 30 allows the bolt 27 to assume the pivoting positions resulting from a more or less deep engagement in the threaded bushings 24 and 25.

Die Gelenkhülse 3 greift zwischen die Schenkel des Gabelkopfes 2 am Gelenkarmende 1 ein, so daß noch ein freier Spalt 4 verbleibt. Dieser freie Spalt 4 ist bei eingefahrener Markise zunächst noch frei. Mit dem Ausfahren der Gelenkarme 26 nähert sich dieser Spalt der in Figur 3 und 4 dargestellten Anschlagschale 6. Wie vor allem Figur 4 zu entnehmen ist, hat die Anschlagschale 6 eine muldenartige Gestalt, so daß sie die Gelenkhülse 3 abfangen kann und deren Bewegung begrenzt. Oberhalb eines bestimmten Ausmaßes der Gelenkarmentfaltung schiebt sich der Rand der Anschlagschale zunehmend in den Spalt 4 des Gabelkopfes ein, wobei die Außenform 5 derart gekrümmt ist, daß sich ein weicher Ablauf vollzieht. Unterstützt wird diese Führung noch durch eine entsprechende Anrundung 7 der muldenförmigen Vertiefung, wie aus Figur 3 erkennbar ist. Sowie eine derartige Stellung zwischen dem Kippgelenk und der Anschlagschale besteht, ist die Lage der Gelenkarme 26 verriegelt, so daß insbesondere die aufgespannte Markise nicht hochschlagen kann. Der Steg des Gabelkopfes kommt vielmehr bei einer derartigen Bewegung an der Rückseite der Anschlagschale 6 zum Anschlag, der die weitere Bewegung nach oben begrenzt. Die Begrenzung des Neigungswinkels der Gelenkarme 26 setzt die Zugänglichkeit des Schraubbolzens 27 von außen voraus. Zu diesem Zweck ist die Anschlagschale 6 in axialer Richtung des Schraubbolzens 27 mit einer Öffnung 31 ausgeführt, durch die sich insbesondere ein Innensechskantschlüssel einführen läßt, der am Kopf des Schraubbolzens 27 angreifen kann.The joint sleeve 3 engages between the legs of the fork head 2 at the end 1 of the articulated arm, so that a free gap 4 still remains. This free gap 4 is initially still free when the awning is retracted. When the articulated arms 26 are extended, this gap approaches the stop shell 6 shown in FIGS. 3 and 4. As can be seen above all in FIG. 4, the stop shell 6 has a trough-like shape, so that it can intercept the joint sleeve 3 and limit its movement. Above a certain extent of the articulation of the joint, the edge of the stop shell is increasingly inserted into the gap 4 of the fork head, the outer shape 5 being such is crooked that a soft process takes place. This guidance is also supported by a corresponding rounding 7 of the trough-shaped depression, as can be seen from FIG. 3. As soon as there is such a position between the tilt joint and the stop shell, the position of the articulated arms 26 is locked so that, in particular, the open awning cannot swing up. Rather, the web of the fork head comes to a stop with such a movement on the rear side of the stop shell 6, which limits the further movement upwards. The limitation of the angle of inclination of the articulated arms 26 presupposes the accessibility of the screw bolt 27 from the outside. For this purpose, the stop shell 6 is designed in the axial direction of the screw bolt 27 with an opening 31 through which, in particular, an Allen key can be inserted which can engage the head of the screw bolt 27.
