Description

Die Erfindung betrifft ein Anzeigeelement für Aufzüge mit in einem Gehäuse angeordneten Anzeigeeinrichtungen, die den Betriebszustand der Aufzugskabine signalisieren.The invention relates to a display element for elevators with display devices arranged in a housing, which signal the operating state of the elevator car.

Aus der Patentschrift CH 270 934 ist ein für Schalt- und Signalzwecke verwendbares Element bekannt, das in einem Gehäuse Schalter, Stockwerkanzeiger und Fahrrichtungsanzeiger aufnehmen kann. Das Gehäuse wird in eine Wandaussparung eingelassen und wandbündig mit einer Deckplatte abgeschlossen. Bei Elementen, die als Fahrrichtungsanzeiger verwendet werden, sind im Gehäuse angeordnete Glühbirnenfassungen mit Glühbirnen vorgesehen. Dabei wird in eine Aussparung am oberen Rand des Gehäuses eine einen Pfeil tragende Glasscheibe eingelegt und in einen Schlitz der Deckplatte eine durchscheinende Opalglasscheibe eingesetzt.From the patent CH 270 934 an element can be used for switching and signaling purposes is known, which can accommodate switches, floor indicators and direction indicators in a housing. The housing is embedded in a wall recess and finished flush with a cover plate. In the case of elements which are used as direction indicators, light bulb sockets with light bulbs are provided in the housing. A glass pane bearing an arrow is inserted into a recess in the upper edge of the housing and a translucent opal glass pane is inserted into a slot in the cover plate.

Ein Nachteil der bekannten Einrichtung liegt darin, dass aufwendige Wandaussparungen notwendig sind, die die vor Ort Montagearbeiten erheblich vergrössern. Normalerweise müssen die Wandaussparungen bereits beim Bau des Gebäudes angebracht werden. Dazu ist fachkundiges Personal vor der eigentlichen Aufzugsmontage auf der Baustelle erforderlich. Ein weiterer Nachteil liegt darin, dass bei nachträglicher Änderung oder Modernisierung einer Aufzugsanlage Wandaussparungen aus baulichen Gründen nicht an beliebigen Stellen des Aufzugsportals und nur mit vermehrtem Aufwand angebracht werden können.A disadvantage of the known device is that complex wall recesses are necessary, which considerably increase the assembly work on site. Usually, the wall recesses must be made when the building is being built. This requires specialist personnel before actually installing the elevator on the construction site. Another disadvantage is that when a lift system is subsequently changed or modernized, for structural reasons, wall cutouts cannot be made at any point on the lift portal and only with increased effort.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, die Nachteile der bekannten Einrichtung zu vermeiden und ein Anzeigeelement zu schaffen, das ohne Wandaussparung montiert werden kann, ohne dass dabei die ästhetische Aufmachung des Aufzugsportals in negativer Weise beeinträchtigt wird.The invention seeks to remedy this. The invention as characterized in the claims solves the Task to avoid the disadvantages of the known device and to create a display element that can be mounted without a wall recess, without the aesthetic appearance of the elevator portal being adversely affected.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass eine gebäudekonstruktionsunabhängige Anordnung des Anzeigeelementes möglich ist und dass den Kunden- und Architektenwünschen dank der einfachen Montage des Anzeigeelementes besser entsprochen werden kann. Ein weiterer Vorteil ist darin zu sehen, dass das Anzeigeelement weitgehend Schutz gegen unbefugtes Öffnen bietet.The advantages achieved by the invention are essentially to be seen in the fact that an arrangement of the display element that is independent of the building construction is possible and that customer and architect wishes can be better met thanks to the simple assembly of the display element. Another advantage is that the display element offers extensive protection against unauthorized opening.

In den Fig. 1 bis 6 ist mit 1 eine Wand bezeichnet, auf der mittels Befestigungsschrauben 2 eine Grundplatte 3 mit auf den Schmalseiten aufgebogenen Enden 4 montiert ist. An der unteren Schmalseite eines wandseitig geöffneten Gehäuses 5 sind Bolzen 6 angeordnet, die das Gehäuse 5 mit dem unteren aufgebogenen Ende 4 verbinden. An der oberen Schmalseite des Gehäuses 5 verbinden Stellschrauben 7 das Gehäuse 5 mit dem oberen aufgebogenen Ende 4 der Grundplatte 3. Mit T ist die Tiefe des Gehäuses 5 oder das Vorstehen des Gehäuses 5 von der Wand 1 bezeichnet. Frontseitig weist das Gehäuse 5 eine Öffnung auf, in die eine Filterplatte 8 eingelegt ist. An der Frontinnenseite des Gehäuses 5 nahe der Öffnung angeordnete Gewindebolzen 9 halten an Laschen 10 einen Linsenträger 11, der mittels Muttern frontseitig auf die Filterplatte 8 gepresst wird. Rückseitig schliesst eine auf den Linsenträger 11 aufgesetzte schwarze gedruckte Schaltung 12 den Linsenträger 11 ab. Eine an der Grundplatte 3 angeordnete Isolierplatte 13 schützt die gedruckte Schaltung 12 vor Kurzschlüssen.1 to 6, 1 denotes a wall on which a base plate 3 with ends 4 bent up on the narrow sides is mounted by means of fastening screws 2. On the lower narrow side of a housing 5 open on the wall, bolts 6 are arranged which connect the housing 5 to the lower bent end 4. On the upper narrow side of the housing 5, set screws 7 connect the housing 5 to the upper bent end 4 of the base plate 3. T denotes the depth of the housing 5 or the protrusion of the housing 5 from the wall 1. At the front, the housing 5 has an opening into which a filter plate 8 is inserted. On the front inside of the housing 5 near the opening, threaded bolts 9 hold tabs 10 on a lens carrier 11, which is pressed onto the filter plate 8 by means of nuts on the front. On the back, a black printed circuit 12 placed on the lens carrier 11 closes off the lens carrier 11. An insulating plate 13 arranged on the base plate 3 protects the printed circuit 12 from short circuits.

Der Linsenträger 11 besteht aus einem Trägerrahmen 14 mit den Laschen 10 und einer frontseitigen schwarzen Trägerwand 15. In die Trägerwand 15 sind in der Form symbolabhängige Linsen 16 eingelassen, die auf der Rückseite der Trägerwand 15 von vorstehenden Linsengehäusen 17 umfasst werden. Rückseitig wird der Linsenträger 11 von der gedruckten Schaltung 12 abgeschlossen, wobei diese von in Bohrungen 18 eingreifenden Trägerbolzen 19 des Linsenträgers 11 gehalten wird. Für die Ansteuerung der auf der gedruckten Schaltung 12 angeordneten Schaltkreise vorgesehene Anschlussdrähte 20 verlassen den geschlossenen Linsenträger 11 über eine Aussparung 21.The lens carrier 11 consists of a carrier frame 14 with the tabs 10 and a black carrier wall 15 on the front. In the carrier wall 15, symbol-dependent lenses 16 are embedded in the form, which are encompassed on the back of the carrier wall 15 by projecting lens housings 17. On the back, the lens carrier 11 is closed off by the printed circuit 12, which is held by carrier bolts 19 of the lens carrier 11 which engage in bores 18. The connecting wires 20 provided for controlling the circuits arranged on the printed circuit 12 leave the closed lens carrier 11 via a cutout 21.

Bei der vorliegenden Ausführungsvariante sind auf der gedruckten Schaltung 12 in Serie geschaltete Leuchtdioden 22 pfeilförmig angeordnet, die mittels Leiterbahnen 23 elektrisch miteinander verbunden sind. Ein erster Anschlussdraht 20 steuert die nach oben gerichtete Pfeilspitze und den Pfeilbalken an, ein zweiter Anschlussdraht 20 steuert die nach unten gerichtete Pfeilspitze und den Pfeilbalken an. Als gemeinsamer Rückleiter dient ein dritter Anschlussdraht 20. Bei geschlossenem Linsenträger 11 tauchen die Leuchtdioden 22 in die Linsengehäuse 17 ein, so dass das Diodenlicht von den Linsen 16 gebündelt nach aussen auf die Filterplatte 8 weitergeleitet wird.In the present embodiment variant, light-emitting diodes 22 connected in series are arranged on the printed circuit 12 in an arrow shape and are electrically connected to one another by means of conductor tracks 23. A first connecting wire 20 controls the upward arrowhead and the arrow bar, a second connecting wire 20 controls the downward arrowhead and the arrow bar. A third connecting wire 20 serves as a common return conductor. When the lens holder 11 is closed, the light-emitting diodes 22 dip into the lens housing 17, so that the diode light is bundled outward by the lenses 16 and passed on to the filter plate 8.

In einer weiteren Ausführungsvariante sind im Gehäuse 5 angeordnete nicht dargestellte mikromechanische Druckschalter oder kapazitive Schalteinrichtungen als Stockwerkrufgeber oder akustische Einrichtungen zur Vermittlung von Audioinformation vorgesehen.In a further embodiment variant, micromechanical pressure switches or capacitive switching devices (not shown) arranged in the housing 5 are provided as floor call transmitters or acoustic devices for conveying audio information.
