Abstract
Description
Die Erfindung bezieht sich auf eine elektrische Scherengitterleuchte.The invention relates to an electric scissor lattice lamp.
Es sind elektrische Leuchten bekannt, bei denen ein Leuchtmittel an dem einen Ende eines Scherengitters befestigt ist, dessen anderes Ende ortsfest, eventuell verschwenkbar, gehaltert ist. Durch Zusammenschieben oder Auseinanderziehen sowie durch Verschwenken des Scherengitters kann die Position des Leuchtmittels im Raum verändert werden. Das Leuchtmittel ist dabei über ein entlang dem Scherengitter geführtes Kabel mit einer Stromquelle verbunden.Electric lights are known in which a lamp attached to one end of a scissor grid the other end of which is stationary, possibly pivotable, is supported. By pushing or pulling apart as well as by pivoting the scissor lattice The position of the lamp in the room can be changed. The Illuminant is a along the scissor lattice guided cable connected to a power source.
Es sind auch Scherengitterleuchten bekannt, die als horizontal ausziehbare Hängeleuchten ausgebildet sind. Dabei ist an mehreren Gliedern eines horizontal verlaufenden Scherengitters jeweils ein Leuchtmittel angebracht, die im zusammengeschobenen Zustand des Scherengitters eine kompakte Leuchtmittel-Anordnung und im auseinandergezogenen Zustand des Scherengitters eine gerade Leuchtmittelreihe ausbilden. Auf diese Weise kann z. B. ein ausziehbarer Tisch immer gleichmäßig beleuchtet werden.There are also scissor lattice lights known as horizontal extendable pendant lights are designed. Here is horizontal on several links Scissor lattice attached a lamp, which in collapsed condition of the scissor lattice a compact Bulb arrangement and in the exploded Condition of the scissor lattice a straight row of lamps form. In this way, e.g. B. a pull-out Table is always illuminated evenly.
Nachteilig ist bei diesen elektrischen Scherengitterleuchten jedoch, daß entweder die Anschlußkabel für alle Leuchtmittel außerhalb des Scherengitters an diesem entlang geführt werden müssen, was den ästhetischen Eindruck stark beeinträchtigt, oder daß die Glieder des Scherengitters hohl ausgebildet werden müssen, um in ihrem Inneren diese Anschlußkabel aufnehmen zu können. Die letztere Ausführungsform ist zwar ästhetisch ansprechender, bringt jedoch einen erhöhten Fertigungsaufwand mit sich und ist daher kostspielig.A disadvantage of these electric scissor lattice lights however, that either the connection cable for all lamps guided along the outside of the scissor grid need to be what the aesthetic impression is strong impaired, or that the limbs of the scissor lattice have to be hollow to get this inside To be able to accommodate connection cables. The latter embodiment is more aesthetically pleasing, but it brings an increased manufacturing effort and is therefore expensive.
Hier soll nun die Erfindung Abhilfe schaffen und eine elektrische Scherengitterleuchte so verbessern, daß bei verringerten Fertigungskosten eine ausziehbare Leuchte mit wenigen sichtbaren elektrischen Anschlußelementen geschaffen wird.Here, the invention is to remedy the situation and an electrical one Improve the scissor lattice light so that at reduced Manufacturing costs with an extendable lamp few visible electrical connection elements created becomes.
Erfindungsgemäß wird dies bei einer elektrischen Scherengitterleuchte dadurch erreicht, daß sie zwei gleiche zueinander parallel verlaufende Scherengitter aus elektrisch leitendem Material aufweist, die jeweils an einen der Pole einer Niederspannungsquelle angeschlossen sind und deren Gelenkpunkte jeweils einander gegenüberliegen, wobei mindestens zwei einander gegenüberliegende Gelenkpunkte mit Sofittenanschlüssen versehen und durch ein Sofittenglühlämpchen miteinander verbunden sind.According to the invention, this is the case with an electric scissor lattice lamp in that they are two equal to each other parallel scissor grids made of electrical has conductive material, each on one of the poles are connected to a low voltage source and their Pivot points are opposite each other, at least two opposite hinge points with sofa connections provided and by a sofa light bulb are interconnected.
Eine erfindungsgemäß ausgebildete Scherengitterleuchte ist auf Grund ihrer relativ einfachen Konstruktion leicht herstellbar und weist bis auf die beiden Scherengitter selbst und deren Anschluß an eine Niederspannungsquelle keine weiteren elektrischen Anschlußmittel auf, die zu den einzelnen Leuchtmitteln geführt werden müssen. Daher stören bei dieser Scherengitterleuchte keine an den Scherengittern entlanggeführte Kabel den optischen Eindruck. Dadurch, daß zwei parallel zueinander verlaufende Scherengitter aus elektrisch leitendem Material verwendet werden, kann die Tragkonstruktion der Leuchte gleichzeitig auch als deren elektrischer Leiter eingesetzt werden, um die Leuchtmittel mit Strom zu versorgen. Ein Sicherheitsrisiko für Benutzer der Leuchte besteht dabei nicht, da die Scherengitter lediglich an eine Niederspannungsquelle angeschlossen sind. Die zueinander parallel verlaufenden Scherengitter sind so angeordnet, daß ihre Gelenkpunkte einander gegenüberliegen und zum Anschluß von Leuchtmitteln verwendet werden können. Es ist vorgesehen, diejenigen Gelenkpunkte, die Leuchtmittel aufnehmen sollen, mit Sofittenanschlüssen zu versehen und durch Sofittenglühlämpchen miteinander zu verbinden, wodurch ein gleichermaßen einfacher und kostengünstiger Einbau von Leuchtmitteln ermöglicht wird. Es ist aber auch möglich, die Sofittenglühlämpchen gegen andere, ähnliche Leuchtmittel auszutauschen. A scissor lattice lamp designed according to the invention is easy to manufacture due to its relatively simple construction and points to the two scissor lattices themselves and their connection to a low voltage source no further electrical connection means on to the individual Illuminants must be performed. Therefore interfere with this Scissor lattice light none guided along the scissor grids Cable the visual impression. As a result of that two scissor grids running parallel to each other electrically conductive material can be used Support structure of the lamp at the same time as its electrical conductors are used to illuminate the lamp to supply with electricity. A security risk for users the lamp does not exist because the scissor lattice only are connected to a low voltage source. The scissor grids running parallel to each other are like this arranged that their hinge points are opposite each other and can be used to connect lamps. It is envisaged that those hinge points, the bulbs should record, to provide with Sofittenenschlützen and to connect with each other by means of small incandescent lamps, making it an equally simple and inexpensive Installation of illuminants is made possible. But it is also possible, the Sofitten light bulbs against others, similar Replace bulbs.
Bevorzugt bestehen die Scherengitter aus elektrisch leitendem Metall. Mit dem Einsatz dieses kostengünstigen Materials können die Fertigungskosten noch weiter gesenkt werden. In vorteilhafter Weiterbildung der Erfindung sind die einander gegenüberliegenden, nicht durch Sofittenglühlämpchen miteinander verbundenen Gelenkpunkte über elektrisch isolierende Abstandshalter miteinander verbunden. Damit wird die Stabilität einer erfindungsgemäßen Scherengitterleuchte aus der Scherengitterebene heraus erheblich erhöht, und gleichzeitig werden unplanmäßige Beanspruchungen von Sofittenglühlämpchen auf Grund eines eventuellen seitlichen Auswanderns der Scherengitter bei deren Zusammenschieben oder Auseinanderziehen stark verringert.The scissor lattices preferably consist of electrically conductive Metal. With the use of this inexpensive material manufacturing costs can be reduced even further. In an advantageous development of the invention, they are each other opposite, not by Sofitten incandescent lamps interconnected articulation points via electrically insulating Spacers connected together. So that will the stability of a scissor lattice lamp according to the invention considerably increased out of the scissor lattice level, and at the same time there are unplanned stresses on Sofitten incandescent lamps due to a possible lateral migration the scissor lattice when they are pushed together or Pull apart greatly reduced.
Bei einer ebenfalls vorteilhaften Ausgestaltung der Erfindung sind eine Reihe in Ausziehrichtung der Scherengitter hintereinanderliegender Gelenkpunkte mit den jeweils gegenüberliegenden Gelenkpunkten durch Sofittenglühlämpchen verbunden. Damit wird es möglich, die Länge der beleuchteten Fläche durch Zusammenschieben oder Auseinanderziehen der Scherengitter den veränderlichen Gegebenheiten, wie z. B. der Länge eines ausziehbaren Tisches, problemlos anzupassen.In a likewise advantageous embodiment of the invention are a row in the pull-out direction of the scissor lattice successive articulation points with the opposite Joint points connected by Sofitten light bulbs. This makes it possible to see the length of the illuminated Surface by pushing or pulling the Scissor lattice the changing circumstances, such as. B. the length of an extendable table, easy to adjust.
Besonders bevorzugt ist eine Reihe in der Ebene der Scherengitter außenliegender Gelenkpunkte mit den jeweils gegenüberliegenden Gelenkpunkten durch Sofittenglühlämpchen verbunden. Mittels einer derartigen Ausgestaltung wird eine optimale, weil störungsfreie, Beleuchtung durch die erfindungsgemäße Scherengitterleuchte erzielt.A row in the plane of the scissor lattice is particularly preferred external hinge points with the opposite Articulation points through Sofitten light bulbs connected. By means of such a configuration, a optimal because of trouble-free lighting by the invention Scissor lattice lamp achieved.
In einer weiteren günstigen Ausbildung der Erfindung ist die elektrische Scherengitterleuchte an eine 12-Volt-Spannungsquelle angeschlossen. Damit können gängige 12-Volt-Leuchtmittel, wie z. B. 12-Volt-Halogenbirnen, als Leuchtmittel für die erfindungsgemäße elektrische Scherengitterleuchte verwendet werden.In a further favorable embodiment of the invention the electric scissor lattice light to a 12 volt power source connected. This means that common 12-volt lamps, such as B. 12 volt halogen bulbs, as a lamp for the electric scissor lattice light according to the invention be used.
Vorteilhafterweise sind die Scherengitter Teil des Traggerüstes der Scherengitterleuchte. Mit dieser Ausgestaltung kann die Scherengitterleuchte besonders kostengünstig und konstruktiv einfach ausgebildet werden.The scissor lattices are advantageously part of the supporting structure the scissor lattice light. With this configuration can the scissor lattice light particularly inexpensive and be structurally simple.

noch näher erläutert. Es zeigen:
Die in Fig. 1 dargestellte elektrische Scherengitterleuchte
1 weist zwei identische zueinander parallel verlaufende
Scherengitter 2, 3 aus elektrisch leitendem Metall auf. Die
Scherengitter 2, 3 bestehen aus einzelnen flachen, ebenen
Stäben 4, die in ihrer Mitte 5 und an ihren beiden Enden 6
jeweils mit den benachbarten Stäben 4 gelenkig verbunden
sind. Jedes Scherengitter 2, 3 ist an seinen beiden Enden
mit einem kurzen Stab 4a versehen, der jeweils die Mitte 5
des letzten bzw. Endstabes 4 b mit einem Ende des vorletzten
Stabes 4 gleicher Ausrichtung gelenkig verbindet.
Dadurch bleibt ein Ende 6a des Endstabes 4b frei. Zur Ausbildung
der Gelenke 5, 6 sind die Stäbe 4, 4a, 4b mit Bohrungen
versehen, wobei die Bohrungen der zu verbindenden
Stäbe 4, 4a, 4b übereinanderliegen und von Verbindungsmitteln,
wie z. B. Schrauben 7 oder Nieten 8, durchlaufen werden,
um die Gelenkverbindung herzustellen. Die miteinander
verbundenen Stäbe 4, 4a, 4b berühren dabei einander, so daß
die elektrische Leitfähigkeit gewährleistet ist. Die Scherengitter
2, 3 sind so angeordnet, daß sich ihre entsprechenden
Gelenkpunkte 5, 6 gegenüberliegen. The electric scissor lattice lamp shown in Fig. 1

10 in Form von Hohlnieten 8 versehen, in die jeweils ein
Ende eines Sofittenglühlämpchens 11 gesteckt ist, wobei
diese einander gegenüberliegenden Gelenkpunkte der Scherengitter
2, 3 durch Sufittenglühlämpchen 11 miteinander verbunden
sind. Die anderen einander gegenüberliegenden Gelenkpunkte
5, 6 der Scherengitter 2, 3 sind durch elektrisch
isolierende Abstandshalter 12 miteinander verbunden,
so daß die räumliche Stabilität der Scherengitterleuchte 1
gewährleistet ist. Dabei sind die Abstandshalter 12 zwischen
den Scherengittern 2, 3 über Schrauben 7 gehaltert,
die die Bohrungen in den Stäben 4, 4a, 4b durchlaufen und
somit gleichzeitig in diesen Gelenkpunkten 5, 6 die Gelenkverbindung
ausbilden.A
An einem Ende der Scherengitter 2, 3 ist das jeweilige
freie Ende 6a der Endstäbe 4b über elektrische Anschlußmittel
13 an eine (nicht dargestellte) Niederspannungsquelle
angeschlossen. Die Scherengitter 2, 3 dienen somit nicht
nur als ausziehbare oder zusammenschiebbare Tragkonstruktion
einer elektrischen Leuchte, sondern auch als deren
elektrische Leiter, über die die Leuchtmittel 11 mit Strom
versorgt werden.The respective one is at one end of the
In Fig. 2 ist die Scherengitterleuchte 1 aus Fig. 1 als
horizontal ausgerichtete Hängelampe dargestellt. Sie ist
dabei durch an den oberen Gelenkpunkten 6 der Endstäbe 4b
der Scherengitter 2, 3 angreifende Kabel 13 höhenverstellbar
an einer (nur schematisch dargestellten) Befestigungsvorrichtung
15 aufgehängt. Insgesamt ist die Scherengitterleuchte
1 also an vier Kabeln 13, d.h. an beiden Enden
jeden Scherengitters 2, 3, aufgehängt, wobei in der Seitenansicht
der Fig. 2 nur eines der hintereinander liegenden
Scherengitter und dessen zwei Kabel zu sehen sind. Die Befestigungsvorrichtung
weist vier Rollen 15a auf, die in der
Zeichnungsebene und senkrecht dazu mit Abstand zueinander
angeordnet sind. Die beiden Kabel 13 eines Scherengitters
2, 3 laufen nach oben zu jeweils einer von zwei parallel
zur Zeichnungsebene einander gegenüberliegenden Rollen 15a
und über diese wieder nach unten zu einem Gegengewicht 14,
das zwischen der Befestigungsvorrichtung 15 und den Scherengittern
2, 3 liegt und durch dessen vertikales Verschieben
die Höhenlage der Scherengitterleuchte 1 einstellbar
ist.In Fig. 2, the
Die Rollen 15a sind aus elektrisch leitendem Material hergestellt
und gegen einander elektrisch isoliert. In der
Befestigungsvorrichtung 15 ist eine (nicht dargestellte)
Niederspannungsquelle in Form eines Transformators angeordnet,
wobei zwei parallel zur Zeichnungsebene einander
gegenüberliegender Rollen 15a an den einen Pol der Niederspannungsquelle
und die beiden anderen Rollen 15a an den
anderen Pol der Niederspannungsquelle angeschlossen sind.
Die vier, über die Rollen 15a laufenden Kabel 13 sind blank
und dienen so, indem sie die Rollen 15a berühren, neben der
Befestigung der Scherengitterleuchte 1 als deren elektrische
Anschlußmittel.The
In der unteren Gelenkpunktreihe 6, 9 der Scherengitterleuchte
1 sind die ausgebildeten Sofittenanschlüsse 10 erkennbar,
die die Sofittenglühlämpchen 11 aufnehmen. In der
dargestellten Ausführungsform sind in der unteren Gelenkpunktreihe
6, 9 zwischen den Gelenkpunkten 6a an den Enden
der Scherengitter 2, 3 sowie zwischen den Gelenkpunkten 5,
6 der mittleren und oberen Reihe jeweils elektrisch isolierende
Abstandshalter 12 angebracht, wodurch die räumliche
Stabilität aus der Zeichnungsebene heraus gewährleistet
ist. Durch Zusammenschieben der Scherengitter 2, 3 kann die
Leuchtkraft der Sofittenglühlämpchen 11 auf einen kleinen
Bereich konzentriert werden, wohingegen durch Auseinanderziehen
der Scherengitter 2, 3 das von den Sofittenglühlämpchen
11 ausgestrahlte Licht über einen großen langgestreckten
Bereich gleichmäßig verteilt wird. Es ist aber
auch denkbar, daß nur einzelne einander gegenüberliegende
Gelenkpunkte 5, 6 einer Reihe durch Sofittenglühlämpchen 11
miteinander verbunden sind oder daß die Leuchtmittel nicht
in der untersten Gelenkpunktreihe 6 sondern in der mittleren
oder oberen Gelenkpunktreihe 5, 6 bzw. in allen Gelenkpunktreihen
5, 6 angeordnet oder beliebig über diese
verteilt sind. Außer praktischen Erwägungen gibt es hier
keinerlei Beschränkungen.In the
Ferner können die Scherengitter auch senkrecht oder in einem anderen beliebigen Winkel gehaltert sein. Dabei ist neben einer Aufhängung jede andere geeignete Befestigungsart, z. B. über Stützen, möglich. Auch ist eine Aneinanderreihung zweier oder mehrerer Scherengitterleuchten denkbar.Furthermore, the scissor lattice can also be vertical or in be held at any other angle. It is in addition to a suspension, any other suitable type of fastening, e.g. B. over supports possible. It is also a series two or more scissor lattice lights conceivable.
