Coupling with the control element does not take place. Only when the lost correct assignment of control pin and bore in the control member is restored by turning the control member and / or the drive member does the compressed telescopic end of the control pin automatically jump into the bore.

With this section, the control plate is connected so that thrust and tensile forces can be transmitted. At the same time, the possibility of right and left arrangement of the drive is retained.

Description

Die Erfindung bezieht sich auf eine Schieberlüftung mit einem motorbetriebenen Gebläse, deren Lüftungsschieber mittels eines Antriebsmechanismus verstellbar ist, wobei ein Antriebsglied des Antriebsmechanismus zugleich ein Bewegungselement für eine elektrische Schalteinrichtung für einen Elektromotor des Gebläses ist oder damit derart verbunden ist, dass der geschlossenen Schieberlüftung der stillstehende und der ganz geöffneten Schieberlüftung der mit voller Drehzahl laufende Elektromotor zugeordnet ist, wobei das Antriebsglied mit einem Schleifkontakt eines Potentiometers der elektrischen Schalteinrichtung mindestens indirekt bewegungsverbunden ist, das im Stromkreis des Elektromotors liegt, wobei der Schleifkontakt zumindest indirekt über ein drehbar gelagertes Steuerglied mit dem Antriebsglied gekoppelt ist. Eine derartige Schieberlüftung ist durch die GB-A 783 757 bekannt geworden. Diese Druckschrift befasst sich mit einer Lüftungsvorrichtung für einen PKW, wobei der als Drehschieber ausgebildete Lüftungsschieber Teil eines Drosselventils ist. Letzteres gibt dem über einen Einlasskanal eintretenden Luftstrom zum Wageninneren vollständig oder gedrosselt frei. In einer Endstellung wird der Luftstrom vollständig abgesperrt.The invention relates to a slide ventilation with a motor-driven fan, the ventilation slide of which is adjustable by means of a drive mechanism, wherein a drive member of the drive mechanism is at the same time a movement element for an electrical switching device for an electric motor of the fan or is connected in such a way that the closed slide ventilation is stationary and the fully open slide ventilation is assigned to the electric motor running at full speed, the drive member being at least indirectly motionally connected to a sliding contact of a potentiometer of the electrical switching device which is in the circuit of the electric motor, the sliding contact being connected to the drive member at least indirectly via a rotatably mounted control member is coupled. Such a slide ventilation has become known from GB-A 783 757. This document deals with a ventilation device for a car, the ventilation slide designed as a rotary valve being part of a throttle valve. The latter releases the air flow to the interior of the car via an inlet duct, either completely or throttled. The air flow is completely shut off in an end position.

Ausgehend von einer geschlossenen Stellung des drehbaren Lüftungsschiebers, in welcher der Elektromotor des Lüfters stillsteht, bewirkt eine Vorstellung des Antriebsmechanismus zunächst lediglich eine Betätigung des Lüftungsschiebers in die geöffnete Stellung. Wenn letztere erreicht ist, bewirkt eine Weiterbewegung des Antriebsmechanismus eine Einschaltung des Lüftermotors, wobei einer zunehmenden Weiterverstellung eine zunehmende Erhöhung der Drehzahl des Lüftermotors zugeordnet ist. Eine Veränderung der Drehzahl des Lüftermotors beim Übergang vom vollständig geöffneten zum geschlossenen Lüftungsschieber ist mit dieser Schieberlüftung nicht möglich.Starting from a closed position of the rotatable ventilation slide, in which the electric motor of the fan stands still, an introduction of the drive mechanism initially only actuates the ventilation slide into the open position. When the latter is reached, a further movement of the drive mechanism causes the fan motor to be switched on, with an increasing further adjustment being associated with an increasing increase in the speed of the fan motor. Changing the speed of the fan motor during the transition from the fully open to the closed ventilation slide is not possible with this slide ventilation.

Schieberlüftungen für Wohngebäude werden mit einer Gebläseeinheit ausgerüstet, wenn die natürliche Luftzirkulation nicht ausreicht.Slider vents for residential buildings are equipped with a blower unit if the natural air circulation is insufficient.

Damit ist es möglich, bei relativ windstiller Witterung den mit einer derartigen Schieberlüftung ausgestatteten Raum rasch und wirkungsvoll zu entlüften bzw. zu belüften. Zugempfindliche Personen empfinden allerdings den vielfach recht kräftigen Luftstrom als unangenehm. Sofern die Möglichkeit besteht, schalten sie deshalb den Lüfter aus, und dies hat eine ungenügende Be-und Entlüftung des Raums zur Folge.It is thus possible, in relatively windless weather, to ventilate or ventilate the space equipped with such a slide ventilation quickly and effectively. However, people who are sensitive to drafts find the often quite powerful air flow unpleasant. If there is a possibility, switch off the fan and this will result in inadequate ventilation of the room.

Es gibt zwar bereits Schieberlüftungen mit einem in zwei Schaltstufen betreibbaren Gebläse, wobei jeder Schaltstellung des Gebläses eine bestimmte Öffnungsstellung der Schieberlüftung zugeordnet ist. Mit dieser Schieberlüftung ist zwar eine Verbesserung der Situation möglich, jedoch keine individuelle Anpassung an das jeweilige Lüftungsbedürfnis und die Zugempfindlichkeit der im zu belüftenden Raum befindlichen Person.There are already slide vents with a fan that can be operated in two switching stages, with each switch position of the fan being assigned a specific open position of the slide ventilation. With this slide ventilation, an improvement of the situation is possible, however, no individual adaptation to the respective ventilation requirement and the sensitivity to draft of the person in the room to be ventilated.

Die Aufgabe der Erfindung besteht infolgedessen darin, eine Schieberlüftung der eingangs genannten Art so weiterzubilden, dass sie zur Be-und Entlüftung eines Raumes geeignet und eine stufenlose Einstellung der Lüftungswirkung möglich ist.The object of the invention is therefore to develop a slide ventilation of the type mentioned in such a way that it is suitable for ventilation of a room and a continuous adjustment of the ventilation effect is possible.

Zur Lösung dieser Aufgabe wird erfindungsgemäss vorgeschlagen, dass die Schieberlüftung gemäss dem Oberbegriff des Anspruchs 1, entsprechend dem kennzeichnenden Teil dieses Anspruchs ausgebildet ist. Die Verwendung einer ebenen flachen Schieberlüftung macht letztere zum Einbau in Wohngebäude geeignet. Des weiteren ermöglicht die Kulissensteuerung eine stufenlose Veränderung sowohl der Drehzahl des Elektromotors des Lüfters als auch der Öffnungsweite der Schieberlüftung. Mit zunehmenden Verschliessen der Schieberlüftung wird die Motordrehzahl stufenlos reduziert, wobei dann der Motor bei völlig geschlossener Schieberlüftung stillsteht. Umgekehrt läuft der Gebläsemotor bei vollständig geöffneter Schieberlüftung mit höchster Drehzahl. Auf diese Weise ist eine individuelle Anpassung dieser Schieberlüftung an die jeweiligen Bedürfnisse und auch Erfordernisse möglich.To achieve this object, it is proposed according to the invention that the slide ventilation is designed according to the preamble of claim 1, corresponding to the characterizing part of this claim. The use of flat, flat slide ventilation makes the latter suitable for installation in residential buildings. Furthermore, the link control enables a continuous change in both the speed of the electric motor of the fan and the opening width of the slide ventilation. With increasing closing of the slide ventilation, the engine speed is gradually reduced, the engine then standing still when the slide ventilation is completely closed. Conversely, the fan motor runs at maximum speed when the slide ventilation is fully open. In this way an individual adaptation of this slide ventilation to the respective needs and requirements is possible.

Kulissensteuerungen zeichnen sich durch eine besonders einfache und robuste Konstruktion aus und sie bieten darüber hinaus die Möglichkeit, ein öffnenbares Lüftungsgehäuse zu verwenden, dessen Inneres rasch und gründlich gereinigt werden kann. Andererseits ist das Zusammenkuppeln der Kulissensteuerungsteile beim Schliessen des Gehäuses problemlos möglich. Durch das Öffnen des Gehäuses kann man auch die elektrische Schalteinrichtung leicht zugänglich machen. Dies ist gerade bei Verwendung eines Potentiometers von grossem Vorteil. Im übrigen kann auch die Geräuschentwicklung des Lüfters störend sein, so dass man über ein mehr oder weniger starkes Schliessen der Schieberlüftung auch eine individuelle Einstellung des Geräuschpegels erreichen kann.Set controls are characterized by a particularly simple and robust construction and they also offer the possibility of using an openable ventilation housing, the interior of which can be cleaned quickly and thoroughly. On the other hand, coupling of the link control parts when closing the housing is possible without any problems. By opening the housing you can also make the electrical switching device easily accessible. This is of great advantage especially when using a potentiometer. In addition, the noise generated by the fan can also be disruptive, so that an individual adjustment of the noise level can also be achieved by closing the slide ventilation to a greater or lesser extent.

In Weiterbildung der Erfindung wird vorgeschlagen, dass das Antriebsglied oder das Steuerglied einen Steuernocken trägt, der mit einem zusätzlich im Stromkreis des Gebläsemotors liegenden Endschalters zusammenwirkt. Mittels letzterem kann man zumindest einen zusätzlichen Schaltvorgang auslösen, sobald der Steuernokken die entsprechende Drehstellung eingenommen hat bzw. verlässt. Die Zuordnung kann man beispielsweise so treffen, dass der Steuernocken den Schalter bei geschlossener Schieberlüftung in seiner geöffneten Stellung hält und den Schaltmechanismus betätigt, sobald man die Schieberlüftung teilweise oder vollständig öffnet. Über diesen Schalter kann man in vorteilhafter Weise auch noch eine Kontrollampe ein- und ausschalten, um den Betriebszustand des Lüftermotors zu signalisieren.In a further development of the invention, it is proposed that the drive member or the control member carries a control cam which interacts with a limit switch additionally located in the circuit of the blower motor. The latter can be used to trigger at least one additional switching operation as soon as the control cam has assumed or leaves the corresponding rotary position. The assignment can be made, for example, so that the control cam holds the switch in its open position when the slide ventilation is closed and actuates the switching mechanism as soon as the slide ventilation is partially or fully opened. This switch can also be used to advantageously switch a control lamp on and off in order to signal the operating state of the fan motor.

Eine weitere Variante der Erfindung kennzeichnet sich bei einer Schieberlüftung mit einem an einem Gehäusedeckel verschiebbaren Lüftungsschieber dadurch, dass das Antriebsglied als im Lüftungsgehäuse drehbare Scheibe mit dem Steuerzapfen ausgebildet ist und der Steuerschlitz beidendig randoffen sowie durch zwei Ansätze an der dem Antriebsglied zugeordneten Fläche des Lüftungsschiebers gebildet ist, wobei das Antriebsglied zugleich das Steuerglied ist. Diese Schieberlüftung ist gegen falsches Zusammenfügen nach dem Öffnen einwandfrei geschützt. Falls die Relativlage der miteinander zu kuppelnden Teile der Kulissensteuerung nicht stimmt, lässt sich das Gehäuse der Schieberlüftung nicht schliessen, weil dann der Steuerzapfen des Antriebsglieds gegen einen der beiden Ansätze stösst. Erst wenn man den Lüftungsschieber um den notwendigen Korrekturbetrag verschoben hat, kann der Steuerzapfen zwischen die beiden Ansätze treten, wodurch die korrekte Kupplung hergestellt ist und sich das Schiebegehäuse schliessen lässt. Die beiden Ansätze stehen in Bewegungsrichtung des Lüftungsschiebers hintereinander. Sie sind zweckmässigerweise von gleicher Gestalt und Grösse. Wenn beide von den Führungen des Lüftungsschiebers gleichen Abstand haben, so eignet sich diese Ausführung für eine Konstruktion mit einem rechts- und linkslaufenden Stellmotor.Another variant of the invention is characterized in the case of a slide ventilation with a ventilation which can be displaced on a housing cover slide in that the drive member is designed as a rotatable disk in the ventilation housing with the control pin and the control slot is open at both ends and is formed by two approaches on the surface of the ventilation slide assigned to the drive member, the drive member being the control member. This slide ventilation is perfectly protected against incorrect assembly after opening. If the relative position of the parts of the link control to be coupled with one another is incorrect, the housing of the slide ventilation cannot be closed, because the control pin of the drive member then pushes against one of the two approaches. Only when you have moved the ventilation slide by the necessary amount of correction, can the control pin step between the two approaches, whereby the correct coupling is made and the sliding housing can be closed. The two approaches are one behind the other in the direction of movement of the ventilation slide. They are expediently of the same shape and size. If both are at the same distance from the guides of the ventilation slider, this version is suitable for a construction with a right-hand and left-hand actuator.

Eine weitere Ausgestaltung der Erfindung sieht vor, dass die Ansätze der Steuerplatte senkrecht zur Verschieberichtung des Lüftungsschiebers versetzt zueinander angeordnet sind. Auch hierbei ist ein falsches Zusammenkuppeln der Kulissensteuerung ausgeschlossen. Das heisst, ein evtl. vorhandener Klappdeckel lässt sich nicht schliessen, wenn der Steuerzapfen auf einen der beiden Ansätze trifft. Im übrigen eignet sich diese Konstruktion für eine Ausführungsform, bei welcher das Steuerglied nur in einer Richtung drehbar ist.A further embodiment of the invention provides that the lugs of the control plate are arranged offset to one another perpendicular to the direction of displacement of the ventilation slide. Incorrect coupling of the link control is also excluded here. This means that any existing hinged cover cannot be closed when the control pin hits one of the two approaches. Otherwise, this construction is suitable for an embodiment in which the control member can only be rotated in one direction.

Eine andere bevorzugte Ausführungsform der Erfindung besteht darin, dass der Lüftungsschieber an einem Gehäusedeckel verschiebbar gelagert sowie am Steuerglied der Schleifkontakt angebracht ist, und dass das Antriebsglied als im Gehäusedeckel drehbare Scheibe ausgebildet ist, die den Steuerzapfen der Kulissensteuerung trägt, der in eine Bohrung od.dgl. des Steuerglieds eingreift. Weil sich hier der Lüftungsschieber gewissermassen zwischen dem Antriebsglied und dem Steuerglied befindet, durchsetzt der Steuerzapfen den Steuerschlitz des Lüftungsschieber. Mit dem Öffnen des Gehäusedeckels wird der Steuerzapfen vom Steuerglied angekuppelt. Während die Kulissensteuerung zwischen dem Steuerzapfen und dem Schieber der Schieberlüftung aufrechterhalten bleibt. Andererseits ist aber aufgrund dieser Steckverbindung ein Zusammenkuppeln des Steuerzapfens mit dem Steuerglied nur in einer ganz bestimmten Drehstellung des letzteren möglich, in welcher auch der Potentiometereingriff genau definiert ist. Infolgedessen ist auch hier eine falsche Zuordnung des Potentiometerabgriffs zur Schieberstellung ausgeschlossen.Another preferred embodiment of the invention is that the ventilation slide is slidably mounted on a housing cover and is attached to the control member of the sliding contact, and that the drive member is designed as a rotatable disc in the housing cover, which carries the control pin of the link control, which in a hole or. the like of the control element engages. Because here the ventilation slide is to a certain extent between the drive member and the control member, the control pin penetrates the control slot of the ventilation slide. When the housing cover is opened, the control pin is coupled by the control element. While the link control between the control pin and the slide of the slide ventilation is maintained. On the other hand, due to this plug-in connection, coupling the control pin to the control member is only possible in a very specific rotational position of the latter, in which the potentiometer intervention is also precisely defined. As a result, incorrect assignment of the potentiometer tap to the slide position is also excluded here.

In weiterer Ausbildung der Erfindung ist vorgesehen, dass das freie Ende des Steuerzapfens als Teleskopglied ausgebildet ist. Dies ermöglicht ein problemloses automatisches Zusammenkuppeln von Steuerzapfen und Steuerglied auch wenn beim Schliessen des Klappdeckels die Bohrung des Steuerglied mit dem freien Steuerzapfenende nicht fluchtet. Wenn nach dem Schliessen des Klappdeckels das freie Ende des Steuerzapfens auf dem scheibenförmigen Steuerglied auftrifft, so führt dies zu einem Zusammendrücken des Teleskops. Ein Ankuppeln mit dem Steuerglied findet dabei nicht statt. Erst wenn durch Drehen des Steuerglieds und/oder des Antriebsglieds die verloren gegangene richtige Zuordnung von Steuerzapfen und Bohrung im Steuerglied wieder hergestellt ist, springt das zusammengedrückte Teleskopende des Steuerzapfens automatisch in die Bohrung ein. Ab diesem Moment lässt sich dann auch die Motordrehzahl wieder in Abhängigkeit von der Schieberstellung verändern.In a further embodiment of the invention it is provided that the free end of the control pin is designed as a telescopic member. This enables a trouble-free automatic coupling of the control pin and control element even if the bore of the control element is not aligned with the free control pin end when the hinged cover is closed. If the free end of the control pin strikes the disk-shaped control member after the hinged lid has been closed, this leads to a compression of the telescope. Coupling with the control element does not take place. Only when the lost correct assignment of control pin and bore in the control member is restored by turning the control member and / or the drive member does the compressed telescopic end of the control pin automatically jump into the bore. From this moment on, the engine speed can also be changed again depending on the slide position.

Eine Weiterbildung der Erfindung besteht darin, dass das Antriebsglied bzw. das Steuerglied mittels eines, insbesondere elektrischen Stellmotors antreibar ist und der vom Steuernokken betätigbare Endschalter auch ein Schalter für den Stellmotor ist. Über diesen Stellmotor ist ein Fernbetätigen der Schieberlüftung leicht möglich. Ausserdem gestattet er die Montage einer Schieberlüftung in grosser Höhe, wo ein Betätigen des Antriebsglieds von Hand nicht oder zumindest nicht ohne weiteres möglich ist. Der Endschalter kann, wie bereits erläutert, auch andere Aufgaben übernehmen bzw. zusätzlich übernehmen.A further development of the invention consists in that the drive element or the control element can be driven by means of an, in particular electrical, servomotor and the limit switch which can be actuated by the control cam is also a switch for the servomotor. Remote control of the slide ventilation is easily possible via this servomotor. In addition, it allows a slide ventilation to be installed at a great height where it is not possible, or at least not readily possible, to actuate the drive member by hand. As already explained, the limit switch can also take on other tasks or take on additional tasks.

Eine weitere Variante der Erfindung kennzeichnet sich dadurch, dass der Lüftungsschieber zweiteilig ausgebildet ist und aus einem lediglich Lüftungsöffnungen sowie Stege aufweisenden Schieberteil sowie einer den Steuerschlitz der Kulissensteuerung aufweisenden Steuerplatte besteht. Aufgrund dieser Zweiteiligkeit kann man für den Lüftungsschieber einen Abschnitt von sogenannter Meterware verwenden, welche die Herstellung der Schieberlüftung in jeder beliebigen Länge bis zum Maxialwert der Meterware ermöglicht. Mit diesem Abschnitt wird die Steuerplatte so verbunden, dass Schub- und Zugkräfte übertragbar sind. Zugleich bleibt auch die Möglichkeit für Rechts- und Linksanordnung des Antriebs erhalten. Wenn sich der Steuerschlitz an der Steuerplatte befindet, so wird der Steuerzapfen am Antriebs- bzw. Einschaltglied angebracht. Im übrigen muss es sich beim Steuerschlitz nicht notwendigerweise um ein Langloch handeln, vielmehr kann er, wie bei den Ausführungsbeispielen vorgesehen, auch nach einer oder zwei gegenüberliegenden Seiten hin randoffen sein. Dabei kann es sich sowohl um einen ausgestanzten Steuerschlitz handeln als auch um eine durch Leisten oder ähnliche Erhebungen gebildete Nut.A further variant of the invention is characterized in that the ventilation slide is formed in two parts and consists of a slide part having only ventilation openings and webs and a control plate having the control slot of the link control. Due to this two-part design, a section of so-called yard goods can be used for the ventilation slide, which enables the slide ventilation to be produced in any length up to the maximum value of the yard goods. With this section, the control plate is connected so that thrust and tensile forces can be transmitted. At the same time, the possibility of right and left arrangement of the drive is retained. If the control slot is located on the control plate, the control pin is attached to the drive or switch-on element. Otherwise, the control slot does not necessarily have to be an elongated hole; rather, as provided in the exemplary embodiments, it can also be open on one or two opposite sides. This can be both a punched out control slot and a groove formed by strips or similar elevations.

Eine andere Ausgestaltung der Erfindung sieht vor, dass die Steuerplatte über eine Zapfenreihe mit einer Lochreihe einer Lüftungsöffnung gekuppelt ist, wobei jede Lüftungsöffnung des Lüftungsschiebers aus mehreren Lochreihen besteht. Auch bei dieser speziellen, das Eindringen von Insekten verhindernden Ausbildung der Lüftungsschlitze sind trotz Verwendung von Meterware besondere Massnahmen zur Ankupplung der Steuerplatte nicht erforderlich. Im übrigen ist die Steuerplatte vorteilhafterweise in denselben Führungen verschiebbar gelagert, die auch zur Führung des Lüftungsschiebers dienen. Deshalb ist sie mit einem abgekröpften, die Zapfenreihe aufweisenden Kupplungsende ausgestattet, welches den randäussersten Steg des Lüftungsschiebers seitlich übergreift.Another embodiment of the invention provides that the control plate is coupled to a row of holes in a ventilation opening via a row of pins, each ventilation opening of the ventilation slide consisting of several rows of holes. Even with this special ventilation design that prevents insects from entering slots are special measures for coupling the control plate are not necessary despite the use of yard goods. In addition, the control plate is advantageously slidably mounted in the same guides that also serve to guide the ventilation slide. That is why it is equipped with a cranked coupling end that has the row of pins and which laterally overlaps the outermost ridge of the ventilation slider.

Eine bevorzugte Ausführungsform der Erfindung besteht darin, dass an wenigstens einem der Längsränder der Steuerplatte ein Verschiebebegrenzungsschlitz angebracht ist, der mit einem darin eingreifenden Bolzen od.dgl. des Gehäuses eine Schiebebegrenzungsvorrichtung bildet. Man erreicht hierdurch einerseits eine Hubbegrenzung und soweit keine anderweitigen Mittel vorgesehen sind eine exakte Einhaltung der beiden Endstellungen des Lüftungsschiebers. Darüber hinaus ermöglicht diese Ausgestaltung das Anbringen des Lüftungsschiebers an einem öffnenbaren, insbesondere abklappbaren Gehäusedeckel, ohne dass in der sogenannten Reinigungsstellung der Lüftungsschieber in eine für das nachfolgende Zusammenkuppeln mit dem Antrieb ungeeignete Stellung verschoben werden kann. Im übrigen ist es besonders zweckmässig, wenn man zwei einander gegenüberliegende Verschiebebegrenzungsschlitze vorsieht, von denen je nach Anordnung des Antriebs am rechten oder linken Schieberlüftungsende der eine oder andere verwendet wird.A preferred embodiment of the invention is that at least one of the longitudinal edges of the control plate has a displacement limiting slot or the like with a bolt engaging therein. of the housing forms a slide limiting device. This achieves a stroke limitation on the one hand and, provided that no other means are provided, exact adherence to the two end positions of the ventilation slide. In addition, this configuration enables the ventilation slide to be attached to an openable, in particular hinged, housing cover without the ventilation slide being able to be moved into a position unsuitable for subsequent coupling with the drive in the so-called cleaning position. In addition, it is particularly expedient to provide two mutually opposite displacement limiting slots, one or the other of which is used depending on the arrangement of the drive on the right or left slide ventilation end.

Schliesslich ist es auch noch besonders vorteilhaft, dass der Deckel als Klappdeckel einer Schall-und/oder wärmegedämmten Schieberlüftung ausgebildet ist. Man vermeidet durch die letztgenannte Ausbildung nicht nur das Eindringen des Aussenlärms und die Bildung einer Kältebrücke in der kalten Jahreszeit, sondern auch die Übertragung des Lüftergeräuschs nach innen sowie eine Beeinträchtigung von Lüfter und Lüftermotor bei besonders kalter Aussenluft.Finally, it is also particularly advantageous that the cover is designed as a hinged cover of a sound and / or heat-insulated slide ventilation. The last-mentioned training not only avoids the penetration of outside noise and the formation of a cold bridge in the cold season, but also the transmission of fan noise to the inside and impairment of the fan and fan motor when the outside air is particularly cold.

Die Schieberlüftung besitzt ein wärme- und schallgedämmtes Lüftungsgehäuse 1, das im wesentlichen aus einem festen Gehäuseteil 2 mit etwa U-förmigem Querschnitt und einem bewegbaren, als Deckel 3 ausgebildeten Gehäuseteil besteht, wobei es sich zweckmässigerweise um einen Klappdeckel handelt. Nachdem eine den Strömungskanal mitbildende schräge Wand 4 fest mit dem Deckel 3 verbunden ist, sie also herausgeklappt werden kann, ist bei geöffnetem Deckel 3 das Innere 5 des Lüftungsgehäuses zu Reinigungs- und Inspektionszwecken gut zugänglich.The slide ventilation has a heat and sound-insulated ventilation housing 1, which essentially consists of a fixed housing part 2 with an approximately U-shaped cross section and a movable housing part designed as a cover 3, which is expediently a hinged cover. After an inclined wall 4 forming the flow channel is firmly connected to the cover 3, that is to say it can be folded out, the interior 5 of the ventilation housing is readily accessible for cleaning and inspection purposes when the cover 3 is open.

Am klappbaren Deckel 3 ist der Lüftungsschieber 6 im Sinne des Doppelpfeils 7 verschiebbar gelagert. Daran befinden sich auch die Gehäuse-Lüftungsöffnungen 8, welche gemäss Fig. 1 die Gestalt von hochkant stehenden rechteckigen Durchbrüchen haben. Demgegenüber sind die Lüftungsöffnungen 9 des Lüftungsschiebers 6 aus einer Anzahl von nebeneinander angeordneten, insbesondere in Längsrichtung gegeneinander versetzten Lochgruppen 10 gebildet. Beim Ausführungsbeispiel sind es fünf solcher Reihen. Die Stege 11 zwischen diesen Lüftungsöffnungen des Lüftungsschiebers 6 und des Gehäuses bzw. des Deckels 3 sind im wesentlichen gleich gross. Gemäss Fig. 6 ist der Lüftungsschieber vorteilhafterweise aus zwei Teilen aufgebaut, wobei der grössere, sich über nahezu die gesamte Länge der Schieberlüftung erstreckende Schieberteil 12 ein Abschnitt von sogenannter Meterware, d.h. einem mehrere Meter langen Ausgangsmaterial, ist. Der demgegenüber vergleichsweise kurze Teil des Lüftungsschiebers bildet eine Steuerplatte 13 mit Steuerschlitz 14. An seinem in Fig. 6 linken Ende trägt sie eine Zapfenreihe 15, wobei die Grösse und der Abstand der Zapfen auf die Lochgrösse und den Lochabstand der Lochgruppen 10 abgestimmt ist. Auf diese Weise ist eine rasche und sichere kraftschlüssige Verbindung beider Schieberteile möglich.On the hinged cover 3, the ventilation slide 6 is slidably mounted in the direction of the double arrow 7. There are also the housing ventilation openings 8, which according to FIG. 1 have the shape of upright rectangular openings. In contrast, the ventilation openings 9 of the ventilation slide 6 are formed from a number of hole groups 10 arranged next to one another, in particular offset in the longitudinal direction. In the exemplary embodiment there are five such rows. The webs 11 between these ventilation openings of the ventilation slide 6 and the housing or the cover 3 are essentially the same size. 6, the ventilation slide is advantageously constructed from two parts, the larger slide part 12, which extends over almost the entire length of the slide ventilation, being a section of so-called yard goods, i.e. a raw material several meters long. The comparatively short part of the ventilation slide forms a control plate 13 with a control slot 14. At its left end in FIG. 6, it carries a row of pins 15, the size and spacing of the pins being matched to the hole size and the hole spacing of the hole groups 10. In this way, a quick and secure non-positive connection of both slide parts is possible.

Sämtliche Ausführungsbeispiele dieser Schieberlüftung sind mit einem Gebläse 16 ausgestattet, das über einen nicht gezeigten Gebläsemotor angetrieben wird. Eine lediglich schematisch angedeutete, im wesentlichen aus dem Gebläsemotor, dem Ventilatorrad sowie einer Steuereinheit gebildete Gebläseeinheit 17 befindet sich hinter dem in entsprechende Halterungen 19 des festen Gehäuseteils 2 eingesprengten Abdeckplatte 18. Die Drehzahl des Gebläsemotors ist über ein Potentiometer 20 mit Schleifkontakt 21 veränderbar. Dabei ist ein Antriebsglied 22 (Fig. 3) bzw. 23 (Fig. 4) zugleich ein Einstellglied für die Motordrehzahl des Gebläsemotors. Mit Hilfe des Antriebsglieds wird die Öffnungsweite der Schieberlüftung bestimmt, d.h. es kann den Lüftungsschieber von der ganz geschlossenen in die vollständig geöffnete Lage verschieben und umgekehrt. Zugleich mit dieser Verschiebebewegung wird die Lüfterdrehzahl derart geändert, dass dem geschlossenen Lüftungsschieber der ausgeschaltete Gebläsemotor und der vollständig geöffneten Schieberlüftung der mit Maximaldrehzahl laufende Gebläsemotor zugeordnet sind. Zweckmässigerweise findet noch ein Endschalter 24 Verwendung, der von einem Nocken 25 betätigt wird. Beispielsweise sind die Kontakte im Endschalter und damit der Stromkreis geöffnet, wenn der Nocken 25 den Stössel 26 des Endschalters niederdrückt. Im Stromkreis des Gebläsemotors kann sich auch noch eine Kontrollampe 27 befinden. Wenn sie aufleuchtet, dreht sich der Gebläsemotor mit einer durch die Stellung des Schleifkontakts 21 vorgegebenen Drehzahl. Der Nocken 25 schaltet nicht nur den Stromkreis für den Gebläsemotor, sondern auch denjenigen eines Stellmotors, falls der Lüftungsschieber nicht von Hand verschoben wird.All embodiments of this slide ventilation are equipped with a blower 16 which is driven by a blower motor, not shown. A blower unit 17, which is only indicated schematically and essentially consists of the blower motor, the fan wheel and a control unit, is located behind the cover plate 18 which is blasted into corresponding holders 19 of the fixed housing part 2. The speed of the blower motor can be changed via a potentiometer 20 with sliding contact 21. In this case, a drive member 22 (FIG. 3) or 23 (FIG. 4) is also an adjusting member for the motor speed of the blower motor. The opening width of the slide ventilation is determined with the help of the drive element, ie it can move the ventilation slide from the completely closed to the fully open position and vice versa. At the same time as this shifting movement, the fan speed is changed in such a way that the closed ventilation slide, the switched off fan motor and the fully open one Slider ventilation are assigned to the blower motor running at maximum speed. A limit switch 24, which is actuated by a cam 25, is expediently used. For example, the contacts in the limit switch and thus the circuit are open when the cam 25 depresses the plunger 26 of the limit switch. A control lamp 27 can also be located in the circuit of the blower motor. When it lights up, the blower motor rotates at a speed predetermined by the position of the sliding contact 21. The cam 25 not only switches the circuit for the blower motor, but also that of a servomotor, if the ventilation slide is not moved by hand.

Beim Ausführungsbeispiel der Fig. 3 ist das Antriebsglied 22 drehbar am Deckel 3 gelagert. Es kann mittels einer nicht gezeigten, bei geschlossenem Lüftungsgehäuse aussenliegenden Handhabe, beispielsweise einem Griff, Knebel, Handrad od.dgl. um einen vorgegebenen Betrag gedreht werden. Letzterer ist durch den Antriebsmechanismus vorgegeben und so festgelegt, dass in der einen Drehendstellung die Lüftungsöffnungen des Gehäuses bzw. Deckels 3 und des Lüftungsschiebers 6 deckungsgleich liegen, während sie in der anderen Enstellung jeweils durch die Stege 11 des anderen Teils abgedeckt sind. Eine Verschiebebegrenzung erreicht man vorteilhafterweise dadurch, dass man an der Steuerplatte 13, also dem kurzen Teil des Lüftungsschiebers 6, einen insbesondere randoffenen, sich in Verschieberichtung 7 des Lüftungsschiebers 6 erstreckenden Verschiebebegrenzungsschlitz 28 anbringt, der mit einem nicht gezeigten Anschlagbolzen zusammenwirkt, welchen man in eine entsprechende Bohrung im Bereich der oberen Gehäuseführung 29 des Deckels 3 einsteckt. Im Hinblick auf eine vorteilhafte Rechts- und Linksverwendbarkeit ist beim Ausführungsbeispiel der Fig. 6 auch am unteren Ende der Steuerplatte 13 ein solcher Verschiebebegrenzungsschlitz 28 vorgesehen.In the embodiment of FIG. 3, the drive member 22 is rotatably mounted on the cover 3. It can by means of a handle, not shown, which is external when the ventilation housing is closed, for example a handle, toggle, handwheel or the like. be rotated by a predetermined amount. The latter is predefined by the drive mechanism and is defined in such a way that in one rotational end position the ventilation openings of the housing or cover 3 and the ventilation slide 6 are congruent, while in the other setting they are each covered by the webs 11 of the other part. A displacement limitation is advantageously achieved by attaching to the control plate 13, that is to say the short part of the ventilation slide 6, an in particular open-ended displacement limitation slot 28 which extends in the displacement direction 7 of the ventilation slide 6 and which cooperates with a stop bolt (not shown), which is inserted into a corresponding hole in the area of the upper housing guide 29 of the cover 3. In view of an advantageous right and left usability, such a displacement limiting slot 28 is also provided in the embodiment of FIG. 6 at the lower end of the control plate 13.

Am Antriebsglied 22 ist exzentrisch ein Steuerzapfen 30 gezeigt, dessen freies Ende als Teleskopglied 31 ausgebildet ist. Er durchsetzt den Steuerschlitz 14 der Steuerplatte 13 und bildet damit eine Kulissensteuerung 32. Mit ihrer Hilfe kann die Drehbewegung des Antriebsglieds 22 in eine Verschiebebewegung des Lüftungsschiebers 6 umgesetzt werden. Wenn der Lüftungsschieber 6 die hierfür vorgesehene Verschiebestellung eingenommen hat, greift das Teleskopglied 31 in eine Bohrung 33 eines insbesondere als Steuerscheibe ausgebildeten Steuerglieds 34 ein. Demnach wird also die Drehbewegung der Handhabe für die Lüftungsschieberverstellung über die aus dem Steuerzapfen 30 und der Bohrung 33 bestehende Steckkupplung auf das Steuerglied 34 übertragen. Weil der Schleifkontakt 21 des Potentiometers 20 gelenkig mit dem Steuerglied 34 verbunden ist, bewirkt die Verstellung des Lüftungsschiebers 6 zugleich auch eine Verschiebung des Potentiometerabgriffs.A control pin 30 is shown eccentrically on the drive member 22, the free end of which is designed as a telescopic member 31. It passes through the control slot 14 of the control plate 13 and thus forms a link control 32. With its help, the rotary movement of the drive member 22 can be converted into a displacement movement of the ventilation slide 6. When the ventilation slide 6 has assumed the shift position provided for this purpose, the telescopic member 31 engages in a bore 33 of a control member 34, which is designed in particular as a control disk. Accordingly, the rotary movement of the handle for the ventilation slide adjustment is transmitted to the control member 34 via the plug coupling consisting of the control pin 30 and the bore 33. Because the sliding contact 21 of the potentiometer 20 is articulated to the control member 34, the adjustment of the ventilation slide 6 also causes a displacement of the potentiometer tap.

Sollte der Lüftungsschieber 6 bei geöffneter Schieberlüftung versehentlich verschoben worden sein, so dass beim Schliessen des Deckels 3 das Teleskopglied 31 mit der Bohrung 33 nicht fluchtet, so kann der Deckel trotzdem vollständig geschlossen werden. Dabei wird allerdings das Teleskopglied 31 gegen den Widerstand einer nicht gezeigten Feder in den Steuerzapfen 30 hineingedrückt. Wenn man nachfolgend das Antriebsglied 22 in der richtigen Richtung und um den erforderlichen Betrag dreht, so springt das Teleskopglied 31 aufgrund der Federspannung in die Bohrung 33 hinein, sobald beide miteinander fluchten. Auf diese Weise ist also stets gewährleistet, dass eine bestimmte Öffnungsstellung der Schieberlüftung einem vorgegebenen Potentiometerabgriff und damit einer genau bestimmten Drehzahl des Gebläses zugeordnet ist.If the ventilation slide 6 has been inadvertently moved when the slide ventilation is open, so that when the cover 3 is closed, the telescopic member 31 is not aligned with the bore 33, the cover can still be closed completely. Here, however, the telescopic member 31 is pressed against the resistance of a spring, not shown, in the control pin 30. If the drive member 22 is subsequently rotated in the correct direction and by the required amount, the telescopic member 31 jumps into the bore 33 due to the spring tension as soon as the two are aligned. In this way, it is always ensured that a certain opening position of the slide ventilation is assigned to a predetermined potentiometer tap and thus to a precisely determined speed of the fan.

Beim Ausführungsbeispiel der Fign. 4 und 5 ist das Antriebsglied 23 am ersten bzw. festen Gehäuseteil 2 gelagert und zugleich als Steuerglied 35 ausgebildet. Es wird von einem elektrischen Stellmotor 43 angetrieben und kann unmittelbar auf dessen Antriebsachse sitzen. Sein Steuerzapfen 36, der kein Teleskopglied benötigt und deshalb auch keines aufweist, arbeitet mit einem Steuerschlitz 37 zusammen, welcher durch zwei würfelartige Ansätze 38 und 39 der Steuerplatte 13 gebildet wird und demzufolge beidendig randoffen ist. Auch dieser Steuerschlitz 37 und der Steuerzapfen 36 bilden eine Kulissensteuerung 40, mit der die Drehbewegung des Steuerglieds 35 in eine Hin- und Herbewegung des Lüftungsschiebers 6 umgesetzt werden kann. Dabei geht allerdings die Drehbewegung, wie gesagt, von einem Stellmotor bekannter Bauart und nicht unmittelbar von der Hand einer Bedienungsperson aus.In the embodiment of FIGS. 4 and 5, the drive member 23 is mounted on the first or fixed housing part 2 and at the same time is designed as a control member 35. It is driven by an electric servomotor 43 and can sit directly on its drive axle. Its control pin 36, which does not require a telescopic member and therefore does not have one, works together with a control slot 37, which is formed by two cube-like extensions 38 and 39 of the control plate 13 and is consequently open at both ends. This control slot 37 and the control pin 36 also form a link control 40 with which the rotary movement of the control member 35 can be converted into a back and forth movement of the ventilation slide 6. However, as I said, the rotary movement is based on an actuator of known design and not directly from the hand of an operator.

Ein falsches Ankuppeln der Kulissensteuerung ist auch beim Ausführungsbeispiel der Fig. 4 nicht möglich. Wenn nämlich der Lüftungsschieber versehentlich aus seiner korrekten Lage verschoben wurde und man nachfolgend den Deckel 3 schliessen will, so gelingt das nicht vollständig, weil dann einer der beiden Ansätze 38, 39 gegen das freie Ende des Steuerzapfens 6 schlägt. Das vollständige Schliessen ist demnach nur möglich, wenn man den versehentlich verstellten Lüftungsschieber zunächst wieder in seine korrekte Lage zurückbringt, so dass der Steuerzapfen 36 in den Steuerschlitz 37 eintreten kann.Incorrect coupling of the link control is also not possible in the embodiment of FIG. 4. If the ventilation slide has been accidentally moved from its correct position and you subsequently want to close the lid 3, this will not work completely because one of the two lugs 38, 39 then strikes the free end of the control pin 6. The complete closing is therefore only possible if the accidentally adjusted ventilation slide is first brought back into its correct position so that the control pin 36 can enter the control slot 37.

Die beiden Ansätze 38 und 39 der Fig. 4 liegen genau parallel zueinander und das ermöglicht die Verwendung eines rechts- und linksdrehenden Stellmotors 43. Wenn letzterer jedoch nur eine einzige Drehrichtung hat, so ist es zweckmässig, wenn man die beiden Ansätze 41 und 42 in der aus Fig. 5 ersichtlichen Weise senkrecht zur Verschieberichtung des Lüftungsschiebers 6 gegeneinander versetzt. Vorteilhafterweise haben diese Ansätze 41, 42 eine im Querschnitt etwa dreieckförmige Gestalt.The two approaches 38 and 39 of FIG. 4 lie exactly parallel to one another and this enables the use of a right-hand and left-hand servomotor 43. However, if the latter only has a single direction of rotation, it is expedient if the two approaches 41 and 42 in 5 apparent from FIG. 5 offset perpendicular to the direction of displacement of the ventilation slide 6 against each other. These projections 41, 42 advantageously have an approximately triangular shape in cross section.

Alle drei beschriebenen Varianten - mit Handverstellung oder Stellmotor 43 - kommen in vorteilhafter Weise im wesentlichen mit denselben Bauteilen aus, was die Fertigung und Lagerhaltung vereinfacht bzw. verbilligt.All three described variants - with manual adjustment or servomotor 43 - advantageously come essentially with the same Components, which simplifies or reduces the cost of manufacturing and warehousing.
