Description

Die Erfmdung betrifft eine Markise und insbesondere eine Gelenkarm-Markise mit den im Oberbegriff des Anspruches 1 angegebenen Merkmalen.The Erfmdung relates to an awning and in particular an articulated arm awning with the features specified in the preamble of claim 1.

Demnach weist die Markise die üblichen Grundkomponenten auf, nämlich eine Halterung an den beiden seitlichen Enden der Markise, eine an der Halterung befestigte Basislagerachse sowie eine Tuchwelle zum Auf- und Abwickeln eines Markisentuches, die relativ zur Basislagerachse drehbar und von einem darauf angeordneten Motor angetrieben ist.Accordingly, the awning on the usual basic components, namely a holder at the two lateral ends of the awning, a base bearing axis fixed to the holder and a roller shaft for winding and unwinding of an awning cloth which is rotatable relative to the base bearing axis and driven by a motor arranged thereon ,

Grundsätzlich ist es aus dem Stand der Technik ferner bekannt, in eine Markise Sensoranordnungen zur Erfassung von das Markisentuch beaufschlagenden Wind- und/oder Wasserlasten zu integrieren. So beschreibt die DE 202 07 538 U1 eine Markise, bei der ein Sensor eine beispielsweise durch Windeinwirkung hervorgerufene Relativbewegung einer elastisch verdrehbar auf einer inneren Welle gelagerten Tuchwelle für das Markisentuch erfasst. Der Sensor ist dabei ortsfest montiert und wirkt über ein Drehelement in Form eines Reibrädchens mit einer Umfangsstelle der Wickelwelle zusammen.In principle, it is also known from the prior art to integrate in an awning sensor arrangements for detecting the awning cloth acting wind and / or water loads. That's how it describes DE 202 07 538 U1 an awning in which a sensor detects a caused for example by wind relative movement of an elastically rotatably mounted on an inner shaft cloth roller for the awning fabric. The sensor is mounted stationary and cooperates via a rotary member in the form of a friction wheel with a peripheral point of the winding shaft.

Nachteilig bei dieser Art von Sensor ist die Tatsache, dass der Kontakt zwischen Reibrädchen und Wickelwelle beispielsweise durch Witterungseinflüsse verschlechtert und insoweit keine zuverlässige Detektion der Bewegungen der Tuchwelle erfolgen kann.A disadvantage of this type of sensor is the fact that the contact between the friction wheel and the winding shaft, for example, deteriorates due to weather conditions and so far no reliable detection of the movements of the fabric shaft can be done.

Aus der DE 93 06 368 U1 ist es bekannt, im Innern einer Basislagerachse für die Markise einen dort so bezeichneten Biegebalken mit einem Dehnungsmessstreifen anzuordnen, wobei das auszulenkende Ende des Biegebalkens mit der Basislagerachse in Eingriff steht. Wind- und wasserlastbedingte Bewegungen des Markisentuches werden über die Tuchwelle und den Markisen-Motor mit Untersetzungsgetriebe auf die Basislagerachse übertragen und durch den an die Basislagerachse angekoppelten Biegebalken erfasst. Nachteilig bei dieser Konstruktion ist die Tatsache, dass die Sensoranordnung verborgen im Innern der hohlen Basislagerachse angeordnet und damit nur aufwändig verkabelbar und im Falle eines Defektes nicht ohne Komplettabbau der Markise reparierbar ist.From the DE 93 06 368 U1 It is known to arrange a bending beam so designated therein with a strain gauge inside a base bearing axis for the awning, wherein the auslenkenkende end of the bending beam is in engagement with the base bearing axis. Wind- and water-load-related movements of the awning fabric are transmitted via the fabric shaft and the awning motor with reduction gear to the base bearing axis and detected by the coupled to the base bearing axis bending beam. A disadvantage of this construction is the fact that the sensor arrangement is arranged hidden inside the hollow base bearing axis and thus can be repaired with great difficulty and can not be repaired without complete dismantling of the awning in the event of a defect.

Ausgehend vom geschilderten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Markise mit einer Drehmoment-Sensoranordnung zur Erfassung von das Markisentuch beaufschlagenden Wind- und/oder Wasserlasten so zu verbessern, dass die Drehmoment-Sensoranordnung bei hoher Zuverlässigkeit der Detektion von Markisentuchbewegungen einfach montierbar und auch in Wandmontageposition der Markise gut zugänglich ist.Based on the described prior art, the invention has the object, an awning with a torque sensor arrangement for detecting the awning cloth acting wind and / or water loads to improve so that the torque sensor assembly with high reliability of the detection of awning fabric movements easy to install and also in wall mounting position of the awning is easily accessible.

Diese Aufgabe wird durch die im Kennzeichnungsteil des Anspruches 1 angegebenen Merkmale gelöst. Demnach ist vorgesehen,

  • dass die Basislagerachse drehbar in der Halterung angeordnet ist, und
  • dass die Drehmoment-Sensoranordnung aufweist
    = einen drehfest relativ zur Basislagerachse an deren einem Ende angeordneten Sensorhebel, dessen Sensorarm an der Halterung angeschlagen und damit drehblockiert ist, sowie
    = eine Dehnungssensoranordnung am Sensorarm zwischen dem Sitz des Sensorhebels auf der Basislagerachse und der Drehblockierung des Sensorarms, wobei mit der Dehnungssensoranordnung eine Deformation des Sensorarms aufgrund eines lastbedingten Drehmoments an der Basislagerachse erfassbar ist.
This object is achieved by the features stated in the characterizing part of claim 1. Accordingly, it is envisaged
  • that the base bearing axis is rotatably disposed in the holder, and
  • that has the torque sensor arrangement
    = a rotationally fixed relative to the base bearing axis arranged at one end of the sensor lever, the sensor arm is struck on the bracket and thus rotationally blocked, and
    = a strain sensor arrangement on the sensor arm between the seat of the sensor lever on the base bearing axis and the rotational blocking of the sensor arm, wherein the strain sensor assembly, a deformation of the sensor arm due to a load-related torque on the base bearing axis is detected.

Wie aus den vorstehend wiedergegebenen Merkmalen der Erfindung ohne Weiteres hervorgeht, ist die Drehmoment-Sensoranordnung an einer exponierten Stelle am Ende der Basislagerachse direkt im Bereich der Halterung positioniert und damit im Sinne der erfindungsgemäßen Aufgabe gut zugänglich montiert. Aufgrund der drehfesten Anordnung des Sensorhebels relativ zur Basislagerachse und dessen Anschlagen an der Halterung sind die einzelnen Bauteile der Drehmoment-Sensoranordnung - anders als bei dem Stand der Technik mit Reibrad - definiert zueinander gehalten, die Generierung eines die Wind- und Wasserlasten repräsentierenden Messsignals erfolgt dabei mittels Dehnungssensoren am Biegearm des Sensorhebels. Damit herrschen in der Sensoranordnung sehr definierte Verhältnisse, sodass diese zuverlässig arbeitet und reproduzierbare Signale für die automatische Steuerung der Markise etwa zum Einziehen bei starken Winden erzeugt.As is apparent from the above reproduced features of the invention readily, the torque sensor assembly is positioned at an exposed point at the end of the base bearing axis directly in the region of the holder and thus mounted easily accessible in the context of the task of the invention. Due to the rotationally fixed arrangement of the sensor lever relative to the base bearing axis and its stops on the holder, the individual components of the torque sensor assembly - unlike the prior art with friction - held defined to each other, the generation of a wind and water loads representative measurement signal takes place by means of strain sensors on the bending arm of the sensor lever. Thus, very defined conditions prevail in the sensor arrangement, so that it operates reliably and generates reproducible signals for the automatic control of the awning, for example for pulling in strong winds.

Bevorzugte Weiterbildungen der erfindungsgemäßen Markise sind in den abhängigen Ansprüchen angegeben, deren Merkmale, Einzelheiten und Vorteile in der nachfolgenden Beschreibung eines Ausführungsbeispiels anhand der beigefügten Zeichnungen näher erläutert werden. Es zeigen:

Wie aus Fig. 1 deutlich wird, weist eine als Ganzes mit 1 bezeichnete Markise eine Halterung, z.B. eine konsolenartige Wandhalterung 2 auf, von der in der Zeichnung der rechtwinklig von der Wand abstehende Schenkel 3 im Schnitt erkennbar ist. In einer Lagerbohrung 4 des Schenkels 3 ist eine Basislagerachse 5 drehbar gelagert, auf der ein nur angedeuteter Motor 6 im Innern der Tuchwelle 7 zu deren Rotationsantrieb sitzt. Auf der Tuchwelle 7 ist das mit mehreren Lagen angedeutete Markisentuch 8 aufgewickelt.How out Fig. 1 becomes clear, a designated as a whole with 1 awning on a holder, for example, a console-like wall mount 2, from which in the drawing of the right angle projecting from the wall leg 3 in section can be seen. In a bearing bore 4 of the leg 3, a base bearing shaft 5 is rotatably mounted on which a motor 6 only indicated in the interior of the roller tube 7 is seated to the rotational drive. On the fabric shaft 7 indicated with several layers awning fabric 8 is wound up.

Wie bei derartigen Markisen in Ausführungsform einer Gelenkarm-Markise üblich ist, wird bei einer Betätigung des Motors 6 das den vorderen Rand des Markisentuches tragende Ausfallprofil der Markise 1 unter Aufspreizung der federbelasteten Gelenkarme bis in eine bestimmte Position ausgefahren. Greifen keine Windlasten am Markisentuch 8 an, so befmdet sich das System in Ruhe. Sobald jedoch Windstöße am Markisentuch 8 angreifen, werden Zugkräfte daran erzeugt, die sich als von außen auf die Tuchwelle 7 aufgebrachte Drehmomente auswirken. Diese werden über die Antriebseinheit umfassend den Motor 6 auf die Basislagerachse 5 übertragen und sind dann dort mit der im Folgenden zu erläuternden Drehmoment-Sensoranordnung zu erfassen. Letztere weist dazu einen Sensorhebel 9 auf, der im gezeigten Ausführungsbeispiel mit einem als Innenvierkant ausgebildeten Lagerauge 10 auf einem Lagerabschnitt 11 der Basislagerachse 5 mit dazu kongruentem vierkantigem Außenquerschnitt sitzt. Vor seinem freien Ende 12 ist der Sensorarm 13 des einarmigen Sensorhebels mit einem in radialer Richtung verlaufenden Langloch 14 versehen, in das ein ortsfest an der Halterung 2 sitzender Anschlagbolzen 15 eingreift. Damit ist der Sensorhebel 9 an der Halterung 2 angeschlagen und folglich drehblockiert, was ferner dazu führt, dass auch die Basislagerachse 5 drehfest relativ zum Sensorhebel 9 gehalten ist.As is common in such an awning in the embodiment of an articulated arm awning, the front edge of the awning cloth carrying frontal profile of the awning 1 is extended under spreading of the spring-loaded articulated arms to a certain position upon actuation of the motor. If no wind loads are applied to the awning cloth 8, the system is at rest. However, as soon as gusts attack the awning cloth 8, tensile forces are generated thereon, which act as externally applied to the cloth shaft 7 torques. These are transmitted via the drive unit comprising the motor 6 to the base bearing axis 5 and are then to be detected there with the torque sensor arrangement to be explained below. The latter has to a sensor lever 9, which in the illustrated embodiment with a square as a square trained bearing eye 10 sits on a bearing portion 11 of the base bearing axis 5 with congruent quadrangular outer cross-section. In front of its free end 12, the sensor arm 13 of the one-armed sensor lever is provided with a slot 14 extending in the radial direction into which a stop pin 15 seated fixedly on the holder 2 engages. Thus, the sensor lever 9 is struck on the holder 2 and thus rotationally blocked, which also leads to the fact that the base bearing axis 5 is rotatably held relative to the sensor lever 9.

Wirkt nun aufgrund von Wind- oder Wasserlasten ein Drehmoment D (Fig. 2) auf die Basislagerachse 5, so zeigt diese die Tendenz, sich in ihrer Lagerbohrung 4 zu drehen. Durch die Arretierung aufgrund des Sensorhebels 9 wird diese Drehung jedoch blockiert, der Sensorhebel 9 wird entsprechend im Bereich seines Sensorarmes 13 analog einem Biegebalken deformiert, wie in Fig. 2 punktiert angedeutet ist.Acts now due to wind or water loads a torque D ( Fig. 2 ) on the base bearing axis 5, this shows the tendency to rotate in its bearing bore 4. By locking due to the sensor lever 9, however, this rotation is blocked, the sensor lever 9 is correspondingly deformed in the region of its sensor arm 13 analogous to a bending beam, as in Fig. 2 dotted is indicated.

Diese Biegung kann nun mit Hilfe einer Dehnungssensoranordnung detektiert werden, die aus jeweils einem Folien-Dehnungsmessstreifen 17.1, 17.2 an den einander abgewandten, in Biegerichtung B weisenden Seitenflächen 18.1, 18.2 des Sensorarms 13 erfasst werden. Bei den Folien-Dehnungsmessstreifen 17.1, 17.2 handelt es sich um handelübliche Exemplare mit einem Widerstandsdraht, der seinen elektrischen Widerstand dehnungsabhängig ändert. Ein Beispiel für solche Folien-Dehnungsmessstreifen sind solche der FAE-Serie der Firma Vishay Measurements Group GmbH. Diese Messstreifen bestehen aus einem Konstantan-Messgitter in einem hochflexiblen Polyimid-Träger.This bend can now be detected with the aid of a strain sensor arrangement, which are detected in each case from a foil strain gauge 17.1, 17.2 on the side faces 18.1, 18.2 of the sensor arm 13 facing away from one another and pointing in the bending direction B. The film strain gauges 17.1, 17.2 are commercially available specimens with a resistance wire that changes its electrical resistance depending on strain. An example of such film strain gauges are those of the FAE series from Vishay Measurements Group GmbH. These measuring strips consist of a Konstantan measuring grid in a highly flexible polyimide carrier.

Signaltechnisch vorteilhaft ist die Verwendung von Doppel-Messstreifen (nicht dargestellt), bei denen jeder Messstreifen zwei dehnungsabhängige Widerstände bereit stellt. Damit kann zur einfachen, aber sehr effektiven Signalauswertung eine übliche Wheatstone'sche Brückenschaltung 21 eingesetzt werden, wie sie in Fig. 4 angedeutet ist. Die Brückenschaltung besteht aus vier Brückenzweigen mit den dehnungsabhängigen Widerständen R1 bis R4. Der Effekt der Schaltung besteht darin, dass bei Speisung mit einer Spannung UE an den gegenüberliegenden Punkten die Spannung UA an den anderen beiden Eckpunkten von den Widerstandsverhältnissen innerhalb der vier Brückenzweige R1 bis R4 abhängt. Sind beispielsweise alle vier Widerstände R1 bis R4 in den Brückenzweigen identisch, dann ist die Ausgangsspannung gleich Null. Tritt an einem Widerstand eine Änderung durch eine Dehnung der Dehnungsmessstreifen 17.1, 17.2 ein, so ist die dadurch bewirkte Ausgangsspannung UA ein Maß für die Widerstandsänderung und damit für die diese hervorrufende Dehnung der Dehnungsmessstreifen 17.1, 17.2. Der Auswerteschaltung 19 wird also über die in Fig. 2 und 4 angedeuteten Signalleitungen 20 ein für die Deformation des Sensorarms 13 und damit das an der Basislagerachse 5 angreifendende Drehmoment repräsentative Messsignal zur Verfügung gestellt. Auf dessen Basis kann eine windabhängige Aus- und Einfahrsteuerung der Markise erfolgen.Signal technology advantageous is the use of double measuring strips (not shown), in which each measuring strip two strain-dependent Resistances ready. This can be used for simple, but very effective signal evaluation, a conventional Wheatstone bridge circuit 21, as in Fig. 4 is indicated. The bridge circuit consists of four bridge arms with the strain-dependent resistors R 1 to R 4 . The effect of the circuit is that when supplied with a voltage U E at the opposite points, the voltage U A at the other two vertices on the resistance ratios within the four bridge arms R 1 to R 4 depends. For example, if all four resistors R 1 to R 4 in the bridge arms are identical, then the output voltage is equal to zero. If a change occurs due to an expansion of the strain gages 17.1, 17.2 at a resistor, the output voltage U A produced thereby is a measure of the change in resistance and thus of the strain of the strain gauges 17.1, 17.2 which causes it. The evaluation circuit 19 is thus on the in Fig. 2 and 4 indicated signal lines 20 a for the deformation of the sensor arm 13 and thus the acting on the base bearing axis 5 torque representative measurement signal provided. On the basis of this, a wind-dependent extension and retraction control of the awning can take place.
