Definitions
- the invention relates to a safety device according to the preamble of claim 1.
- Power operated devices such as gates, doors or windows work e.g. together with an electromechanical drive, which in garage doors consists of a guide rail mounted on the garage ceiling, in which a carriage coupled to the gate by means of an articulated rod is guided in a longitudinally movable manner by means of a drive motor and by means of a form-fitting element.
- the form-fitting element runs in a straight line and parallel to the guide rail, with it being elastically fixed at both ends by means of springs.
- the drive is also equipped with a blocking and obstacle shutdown, e.g. is described in DE 35 46 282 C2.
- Such a garage door drive has a high sensitivity, works reliably, but has the disadvantage that the drive cannot distinguish whether the door is supported on the floor or is in contact with an obstacle.
- DE 3514 223 C2 discloses a method for switching off or reversing an electric motor for driving a movable opening closure, the increase in the current drawn by the motor being monitored and the motor being switched off when a preselected setpoint value is exceeded or being switched in the opposite direction.
- This method can be used if the opening closure is a relatively small and light weight device such as window panes, sunroof or the like.
- This method is not absolutely applicable to larger devices, for example garage doors, which come into contact with obstacles when they are closed, in particular if these obstacles are easily crushable bodies located in the area of the pinching or closing edges.
- the invention has for its object to provide a security device that can distinguish on the one hand whether the opening closure is operationally closed or completed, or on the other hand can determine whether the opening closure is in contact with an obstacle .
- the safety device should be such that, if the opening closure is in pressure connection with a hinaernis, it releases it.
- Another object of the invention is to design the safety device so that the user is always informed whether the safety device and / or the drive device is functioning properly.
- the gate There is an obstacle in the path of movement of the gate, for example a person, then the person acts as a partially compliant obstacle, so that the predetermined maximum operating load of the drive device is only exceeded after a longer period of time after the signal S 1 has been emitted. This has the consequence that the safety device switches the drive device so that the opening closure moves in the opposite direction.
- a particularly expedient embodiment provides that the sensor is arranged in the area of the main closing edge of the opening closure. It is expedient if the sensor has the shape of an elastically deformable body which extends along the main closing edge. Within the scope of this inventive concept, it is particularly expedient if the sensor is a body made of rubber or plastic filled with gas or liquid, which is connected via a line to a converter of mechanical impulses into electrical impulses.
- an expedient embodiment of the invention provides that the sensor is designed as a damping body, the squeeze section of which, measured in the direction of movement of the door, is preferably more than 1 cm.
- a garage door 14 is shown in the form of a sectional door.
- the garage door 14 consists of a plurality of slats 22, 24, 26 and 28 which are guided in vertically oriented rails 30 and 32 which run parallel to one another and which also adjoin rails 34 and 36 which also run horizontally but are arranged horizontally.
- the rails 34 and 36 are fastened to the ceiling of the garage by means of fastening means 38.
- the main closing edge 27 of the gate 14, which can be moved back and forth in the direction of the double arrow 20, carries a sensor 18 which is connected to the safety device 10 via a line 8.
- the safety device 10 is in turn connected via a line 6 to a drive device 12 of the gate.
- the safety device 10 serves to control the sequence of movements of the gate 14, that with the drive device 12 with adjustable operating load and means by which the drive device 12 If their specified operating load is exceeded within a certain period of time, cooperates.
- the safety device 10, which can be fastened, for example, to a side wall of the garage, can be operatively connected to the sensor 18 and to the drive device 12.
- the sensor 18 is designed such that it can be brought into operative connection with obstacles crossing the path of movement of the gate 14, in this case emits a signal to the safety device 10 and thus has the effect that the direction of movement of the gate 14 is changed if its movement occurs within a certain period of time after the signal is not interrupted.
- the operating position of the gate 14 is shown in the drawing.
- the slats 22 to 28 are carried by the guide rails 34 and 36. If the safety device is now switched on, the slats 22 to 28 first move in the horizontal direction and then in the vertical direction until they have assumed the position shown in the drawing. The speed of movement of the slats depends on their position. If there is an obstacle between the bottom 4 and the lowest slat 28, then the sensor 18, which is arranged in the region of the main closing edge 27 of the gate 14, is brought into operative connection with the obstacle. As a result, the pressure inside the sensor, which is in the form of an elastically deformable body, which extends along the main closing edge 27 and is filled with gas or liquid, changes. The pressure wave is sent to a converter of mechanical impulses into electrical impulses.
- the signal reaches the safety device 10 via the line 8, which has the consequence that a time measuring unit is switched on, which measures the time within which the set operating load the drive device 12 is exceeded.
- a time measuring unit is switched on, which measures the time within which the set operating load the drive device 12 is exceeded.
- the operating load is only exceeded later than in the case of non-deformable obstacles, so that the drive device is switched over and the slats of the door move upwards in the vertical direction.
- the sensitivity of the sensor can preferably be increased by making it more voluminous.
- the sensor is simultaneously designed as a damping body, the squeeze section of which, measured in the direction of movement of the slats, can be several centimeters.
- the advantages achieved by the invention are, in particular, that it can be achieved with the simplest possible means that the movement sequence of the gate is not only interrupted, but also changed, so that a situation in which the obstacle is jammed cannot occur.
- the safety device (control device) is also designed such that it is connected to a warning device which signals when the sensor is out of operation.
- the control device first receives the signal from the drive device, which signals that the operating load on the drive device has been exceeded and that the sensor is out of operation.
- the order of the incoming signals namely that of the sensor and that of the drive device, is also information about whether the control unit is working properly. If this is not the case, the gate can e.g. operated via a dead man's switch.
Abstract
Description
Die Erfindung betrifft eine Sicherheitseinrichtung nach dem Oberbegriff des Anspruches 1.The invention relates to a safety device according to the preamble of claim 1.
Kraftbetätigte Vorricntungen, wie Tore, Türen oder Fenster, arbeiten z.B. mit einem elektromechanischen Antrieb zusammen, der bei Garagentoren aus einer an der Garagendecke montierten Führungsschiene besteht, in der ein mit dem Tor mittels Gelenkstange gekoppelter Schlitten mittels eines Antriebsmotors und mittels eines formschlüssigen Elementes längsbewegbar geführt ist. Dabei verläuft das formschlüssige Element geradlinig und parallel zur Führungsschiene, wobei es an beiden Enden mittels Federn elastisch ortsfest aufgehängt ist. Der Antrieb ist ferner mit einer Blockier- und Hindernisabschaltung versehen, wie z.B. in der DE 35 46 282 C2 beschrieben ist. Ein solcher Garagentorantrieb hat eine große Ansprechempfindlichkeit, arbeitet betriebssicher, ist jedoch mit dem Nachteil behaftet, daß der Antrieb nicht unterscheiden kann, ob das Tor sich auf dem Boden abstützt oder in Berührung steht mit einem Hindernis.Power operated devices such as gates, doors or windows work e.g. together with an electromechanical drive, which in garage doors consists of a guide rail mounted on the garage ceiling, in which a carriage coupled to the gate by means of an articulated rod is guided in a longitudinally movable manner by means of a drive motor and by means of a form-fitting element. The form-fitting element runs in a straight line and parallel to the guide rail, with it being elastically fixed at both ends by means of springs. The drive is also equipped with a blocking and obstacle shutdown, e.g. is described in DE 35 46 282 C2. Such a garage door drive has a high sensitivity, works reliably, but has the disadvantage that the drive cannot distinguish whether the door is supported on the floor or is in contact with an obstacle.
Ferner ist in der DE 3514 223 C2 ein Verfahren zum Abschalten oder Umsteuern eines Elektromotors für den Antrieb eines bewegbaren Öffnungsverschlusses offenbart, wobei der Anstieg des vom Motor aufgenommenen Stromes überwacht und der Motor bei Überschreiten eines vorgewählten Sollwertes abgeschaltet oder in Gegenlaufrichtung umgeschaltet wird. Dieses Verfahren kann dann genutzt werden, wenn es sich beim Öffnungsverschluß um relativ kleine und geringes Gewicht aufweisende Vorricntungen wie Fensterscheiben, Schiebedach oder dergleichen handelt. Bei größeren Vorrichtungen, z.B. Garagentore, die beim Schließen an Hindernisse stoßen, ist dieses Verfahren nicht unbedingt anwendbar, und zwar insbesondere dann, wenn es sich bei diesen Hindernissen um im Quetsch- oder Schließkantenbereich befindliche und leicht zerstörbare Körper handelt.Furthermore, DE 3514 223 C2 discloses a method for switching off or reversing an electric motor for driving a movable opening closure, the increase in the current drawn by the motor being monitored and the motor being switched off when a preselected setpoint value is exceeded or being switched in the opposite direction. This method can be used if the opening closure is a relatively small and light weight device such as window panes, sunroof or the like. This method is not absolutely applicable to larger devices, for example garage doors, which come into contact with obstacles when they are closed, in particular if these obstacles are easily crushable bodies located in the area of the pinching or closing edges.
Ausgehend von dem obigen Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Sicherheitseinrichtung zu schaffen, die zum einen unterscheiden kann, ob der Öffnungsverschluß betriebsgemäß abschließt bzw. abgeschlossen ist, oder zum anderen feststellen kann, ob der Öffnungsverschluß mit einem Hindernis in Berührung steht. Dabei soll die Sicherheitseinrichtung so beschaffen sein, daß, steht der Öffnungsverschluß mit einem Hinaernis in Druckverbindung, er dieses freigibt. Eine weitere Aufgabe der Erfindung ist es, die Sicherneitseinrichtung so auszubilden, daß der Benutzer immer darüber informiert ist, ob die Sicherneitseinrichtung und/oder die Antriebseinrichtung ordnungsgemäß funktioniert.Based on the above prior art, the invention has for its object to provide a security device that can distinguish on the one hand whether the opening closure is operationally closed or completed, or on the other hand can determine whether the opening closure is in contact with an obstacle . The safety device should be such that, if the opening closure is in pressure connection with a hinaernis, it releases it. Another object of the invention is to design the safety device so that the user is always informed whether the safety device and / or the drive device is functioning properly.
Die gestellte Aufgabe wird bei der gattungsgemäßen Sicherheitseinrichtung erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.The object is achieved in the generic safety device according to the invention by the characterizing features of claim 1.
Man erkennt, daß die Erfindung jedenfalls dann verwirklicht ist, wenn die Sicherheitseinrichtung eine Zeitmeßeinrichtung umfaßt, die durch das Signal S₁ im Zeitpunkt T₁ eingeschaltet wird und die Zeit T = T₁ - T₂ mißt, innerhalb der die Betriebsbelastung der Antriebseinrichtung überschritten wird und das Signal S₂ im Zeitpunkt T₂ abgibt. Dabei handelt es sich regelmäßig um Zeitabschnitte, die im Bereich von Millisekunden liegen. Nimmt der Öffnungsverschluß eine ausgefahrene Position ein, das heißt, er stützt sich auf dem Boden ab, dann wird die Betriebsbelastung innerhalb einer sehr kurzen Zeit nach Abgabe des Signals S₁ überschritten, so daß die Antriebseinrichtung ausgeschaltet und die Bewegung des Öffnungsverschlusses unterbrochen wird. Befindet sich im Bewegungsweg des Tores ein Hindernis, z.B. eine Person, dann wirkt die Person als ein zum Teil nachgiebiges Hindernis, so daß die vorgegebene maximale Betriebsbelastung der Antrieoseinrichtung erst nach einem längeren Zeitabschnitt nach Abgabe des Signals S₁ überschritten wird. Dies hat zur Folge, daß die Sicherheitseinrichtung die Antriebseinrichtung umschaltet, so daß der Öffnungsverschluß sich in entgegengesetzter Richtung bewegt.It can be seen that the invention is implemented in any case if the safety device comprises a time measuring device which is switched on by the signal S 1 at the time T 1 and measures the time T = T 1 - T 2 within which the operating load of the drive device is exceeded is and gives the signal S₂ at the time T₂. These are periods of time that are in the millisecond range. If the opening closure assumes an extended position, that is to say it rests on the floor, then the operating load is exceeded within a very short time after the signal S 1 has been emitted, so that the drive device is switched off and the movement of the opening closure is interrupted. There is an obstacle in the path of movement of the gate, for example a person, then the person acts as a partially compliant obstacle, so that the predetermined maximum operating load of the drive device is only exceeded after a longer period of time after the signal S 1 has been emitted. This has the consequence that the safety device switches the drive device so that the opening closure moves in the opposite direction.
Weitere zweckmäßige und vorteilhafte Ausgestaltung der Erfindung gehen aus den Unteransprüchen hervor.Further expedient and advantageous refinements of the invention emerge from the subclaims.
Eine besonders zweckmäßige Ausgestaltung sieht vor, daß der Fühler im Bereich der Hauptschließkante des Öffnungsverschlusses angeordnet ist. Hierbei ist es zweckmäßig, wenn der Fühler die Form eines elastisch verformbaren Körpers aufweist, der sich entlang der Hauptschließkante erstreckt. Im Rahmen dieses Erfindungsgedankens ist es besonders zweckmäßig, wenn der Fühler ein mit Gas oder Flüssigkeit gefüllter Körper aus Gummi oder Kunststoff ist, der über eine Leitung an einen Umwandler mechanischer Impulse in elektrische Impulse angeschlossen ist.A particularly expedient embodiment provides that the sensor is arranged in the area of the main closing edge of the opening closure. It is expedient if the sensor has the shape of an elastically deformable body which extends along the main closing edge. Within the scope of this inventive concept, it is particularly expedient if the sensor is a body made of rubber or plastic filled with gas or liquid, which is connected via a line to a converter of mechanical impulses into electrical impulses.
Der Vorteil der vorgeschlagenen Sicherheitseinrichtung bestent darin, daß mit ihr herkömmliche Tore, Türen oder dergleichen bestückt werden können. Es handelt sich also um ein separates Teil, bei dem die Länge des Zeitabschnittes einstellbar ist. Schließlich sieht eine zweckmäßige Ausgestaltung der Erfindung vor, daß der Fühler als ein Dämpfungskörper ausgebildet ist, dessen Quetschabschnitt, gemessen in Bewegungsrichtung des Tores, vorzugsweise mehr als 1 cm beträgt.The advantage of the proposed safety device is that conventional gates, doors or the like can be fitted with it. It is therefore a separate part in which the length of the time period can be set. Finally, an expedient embodiment of the invention provides that the sensor is designed as a damping body, the squeeze section of which, measured in the direction of movement of the door, is preferably more than 1 cm.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung schematisch dargestellt und wird im folgenden erläutert.An embodiment of the invention is shown schematically in the drawing and is explained in the following.
In der Zeichnung ist ein Garagentor 14 in Form eines Sektionaltores dargestellt. Das Garagentor 14 besteht aus mehreren Lamellen 22, 24, 26 und 28, die in vertikal ausgerichteten und parallel zueinander verlaufenden Schienen 30 und 32 geführt sind, die sich an ebenfalls parallel verlaufende Schienen 34 und 36, die jedoch horizontal angeordnet sind, anschließen. Die Schienen 34 und 36 sind mittels Befestigungsmittel 38 an der Decke der Garage befestigt. Die Hauptabschlußkante 27 des Tores 14, das in Richtung des Doppelpfeiles 20 hin- und herbewegbar ist, trägt einen Fühler 18, der über eine Leitung 8 an die Sicherheitseinrichtung 10 angeschlossen ist. Die Sicherheitseinrichtung 10 ist ihrerseits über eine Leitung 6 an eine Antriebseinrichtung 12 des Tores angeschlossen.In the drawing, a
Die Sicherheitseinrichtung 10 dient zur Steuerung des Bewegungsablaufs des Tores 14, das mit der Antriebseinrichtung 12 mit einstellbarer Betriebsbelastung sowie Mitteln, durch die die Antriebseinrichtung 12 bei Überschreitung ihrer vorgegebenen Betriebsbelastung innerhalb eines bestimmten Zeitabschnittes ausgeschaltet wird, zusammenarbeitet. Die Sicherheitseinrichtung 10, die z.B. an einer Seitenwand der Garage befestigbar ist, ist mit dem Fühler 18 und mit der Antriebseinrichtung 12 betrieblich verbindbar. Der Fühler 18 ist so ausgebildet, daß er mit den Bewegungsweg des Tores 14 durchquerenden Hindernissen in Wirkverbindung bringbar ist, hierbei ein Signal an die Sicherheitseinrichtung 10 abgibt und somit bewirkt, daß die Bewegungsrichtung des Tores 14 geändert wird, wenn seine Bewegung innerhalb eines bestimmten Zeitabschnittes nach Abgabe des Signals nicht unterbrochen wird. In der Zeicnnung ist die Betriebslage des Tores 14 dargestellt. In der Ruhelage sind die Lamellen 22 bis 28 von den Führungsschienen 34 und 36 getragen. Wird nun die Sicherheitseinrichtung eingeschaltet, bewegen sich die Lamellen 22 bis 28 zunächst in horizontaler Richtung und sodann in vertikaler Richtung, bis sie die in der Zeichnung dargestellte Position eingenommen haben. Dabei ist die Bewegungsgeschwindigkeit der Lamellen von ihrer Lage abhängig. Befindet sich nun zwischen dem Boden 4 und der untersten Lamelle 28 ein Hindernis, dann wird der Fühler 18, der im Bereich der Hauptschließkante 27 des Tores 14 angeordnet ist, mit dem Hindernis in Wirkverbindung gebracht. Dies hat zur Folge, daß der Druck innerhalb des Fühlers, der die Form eines elastisch verformbaren Körpers aufweist, der sich entlang der Hauptschließkante 27 erstreckt und mit Gas oder Flüssigkeit gefüllt ist, sich ändert. Die Druckwelle wird an einen Umwandler mechanischer Impulse in elektrische Impulse geleitet. Von dort aus gelangt das Signal über die Leitung 8 in die Sicherheitseinrichtung 10, was zur Folge hat, daß eine Zeitmeßeinheit eingeschaltet wird, die mißt, innerhalb welcher Zeit die eingestellte Betriebsbelastung der Antriebseinrichtung 12 überschritten wird. Bei verformbaren Hindernissen tritt die Überschreitung der Betriebsbelastung erst später ein als bei nicht verformbaren Hindernissen, so daß die Antriebseinrichtung umgeschaltet wird und die Lamellen des Tores bewegen sich in vertikaler Richtung nach oben. Die Empfindlichkeit des Fühlers kann vorzugsweise dadurch erhöht werden, daß er voluminöser gestaltet ist. In diesem Fall ist der Fühler gleichzeitig als ein Dämpfungskörper ausgebildet, dessen Quetschabschnitt, gemessen in Bewegungsrichtung der Lamellen, mehrere Zentimeter betragen kann.The
Die durch die Erfindung erzielten Vorteile bestehen insbesondere darin, daß mit denkbar einfachen Mitteln erreichbar ist, daß der Bewegungsablauf des Tores nicht nur unterbrochen, sondern auch geändert wird, so daß eine Situation, in der das Hindernis eingeklemmt ist, nicht eintreten kann. Die Sicherheitseinrichtung (Steuerungseinrichtung) ist ferner so beschaffen, daß sie an eine Warneinricntung angeschlossen ist, die signalisiert, wenn der Fühler außer Betrieb ist. In diesem Falle gelangt in die Steuerungseinrichtung zunächst das Signal der Antriebseinrichtung, das signalisiert, daß die Betriebsbelastung der Antriebseinrichtung überschritten worden ist und daß der Fühler außer Betrieb ist. Die Reihenfolge der ankommenden Signale, nämlich das vom Fühler und das von der Antriebseinrichtung, ist auch eine Information darüber, ob die Steuerungseinheit ordnungsgemäß arbeitet. Ist dies nicht der Fall, dann kann das Tor z.B. über eine Totmannschaltung betrieben werden.The advantages achieved by the invention are, in particular, that it can be achieved with the simplest possible means that the movement sequence of the gate is not only interrupted, but also changed, so that a situation in which the obstacle is jammed cannot occur. The safety device (control device) is also designed such that it is connected to a warning device which signals when the sensor is out of operation. In this case, the control device first receives the signal from the drive device, which signals that the operating load on the drive device has been exceeded and that the sensor is out of operation. The order of the incoming signals, namely that of the sensor and that of the drive device, is also information about whether the control unit is working properly. If this is not the case, the gate can e.g. operated via a dead man's switch.
