Description

Lampenschirm zur Aufnahme eines Leuchtmittels Lampshade for holding a bulb
Beschreibungdescription
Die vorliegende Erfindung bezieht sich auf einen Lampenschirm zur Aufnahme eines Leuchtmittels, wie durch den Oberbegriff des Patentanspruches 1 beschrieben.The present invention relates to a lampshade for receiving a light source, as described by the preamble of claim 1.
Die Beleuchtungsindustrie hat in den vergangenen 30 Jahren eine enorme Wandlung durchlaufen. Leuchten und Lampen haben sich von mehr oder weniger zweckmäßigen Einrichtun- gen zu Designobjekten entwickelt, die nicht nur durch ihr äußeres Erscheinungsbild sondern auch durch die Art und Weise, wie sie das Licht an die Umgebung abgeben, zu einem wesentlichen und unverzichtbaren Stilelement von Innenarchitekten entwickelt haben.The lighting industry has undergone tremendous change over the past 30 years. Luminaires and lamps have evolved from more or less expedient furnishings to design objects that evolve into an essential and indispensable stylistic element of interior decorators, not just by their appearance but also by the way they emit light to their surroundings to have.
Eine besondere Leuchtenform hat sich dabei herausgebildet, die es ermöglicht, die Art und Weise der Lichtabgabe zu beeinflussen, indem ein Lampenschirm mit austauschbaren Filteroder Linsenelernenten versehen werden kann, die in einer Öffnung des Lampenschirmes angeordnet werden, wodurch die Lichtabgabe der Leuchte der jeweiligen räumlichen Situation und Stimmung angepasst werden kann.A special form of luminaire has been developed, which makes it possible to influence the way the light output by a lampshade can be provided with replaceable filter or Linsenelernenten, which are arranged in an opening of the lampshade, whereby the light output of the lamp of the respective spatial situation and mood can be adjusted.
Als problematisch hat sich dabei die zuverlässige austauschbare Halterung der Filter- und/oder Linsenelemente in der Öffnung des Lampenschirmes erwiesen, da die meist aus Glas oder einem vergleichbaren Material bestehenden Filter- und/oder Linsenelemente in der Regel als bruchgefährdet erwiesen haben, wenn sie Kräften oder mechanischen Spannungen während des Einsetzens oder Herausnehmens ausgesetzt werden.As a problem, the reliable interchangeable mounting of the filter and / or lens elements in the opening of the lampshade has proven to be problematic, since the usually made of glass or a comparable material filter and / or lens elements have usually proven to be vulnerable to breakage, if they are forces or mechanical stresses during insertion or removal.
Die Aufgabe der vorliegenden Erfindung ist es daher, einen Lampenschirm der beschriebenen Art vorzusehen, der eine einfach und sichere Möglichkeit der austauschbaren Halterung von Filtern/Linsen in einer Öffnung in dem Lampenschirm bietet. Diese Aufgabe wird durch die Merkmale des unabhängigen Anspruches 1 gelöst wobei zweckmäßige Ausführungsformen durch die Merkmale der Unteransprüche beschrieben sind.The object of the present invention is therefore to provide a lampshade of the type described, which offers a simple and secure way of exchangeable mounting of filters / lenses in an opening in the lampshade. This object is achieved by the features of independent claim 1, wherein expedient embodiments are described by the features of the subclaims.
Vorgesehen ist demnach ein Lampenschirm zur Aufnahme eines Leuchtmittels, mit einem Schirmkörper, der zumindest eine Öffnung zur austauschbaren Anordnung eines Filters/Linse aufweist, wobei der Schirmkörper nach Maßgabe der vorliegenden Erfindung mit zumindest einem feststehenden Filter/Linsenaufhahmeelement und einem diesem im wesentlichen gegenüberliegenden über den Rand der Öffnung hinausbeweglichen FiI- ter/Linsenaufnahmeelement versehen ist. Durch das Vorsehen einerseits des zumindest einen am Schirm fixierten, feststehenden Filter-/Linsenaufnahmeelements und andererseits des über den Rand der Öffnung hinausbeweglichen Filter-/Linsenaufnahmeelements gestaltet sich das Einsetzen bzw. Herausnehmen eines jeweiligen Filters oder einer Linse als denkbar einfach. Zur jeweiligen Manipulation wird das bewegliche Filter-/Linsenäufnahmeelement in eine über den Rand der Öffnung hinausstehende Postion gebracht, wodurch sich der derzeit gehaltene Filter bzw. die derzeit gehaltene Linse einfach mit den Fingern an den Rändern desselben greifen und aus der Halterung entnehmen lässt, bzw. vice versa. Ist der gewünschte Austausch erfolgt, wird das bewegliche Filter-/Linsenaufnalimeelement einfach wieder in seine nicht über den Rand der Öffnung vorstehende Position gebracht wodurch der Rand des Filters bzw. der Linse ebenfalls innerhalb der Öffnung des Schirmes in Anordnung kommt.Accordingly, a lampshade is provided for receiving a luminous means, with a screen body having at least one opening for interchangeable arrangement of a filter / lens, wherein the screen body in accordance with the present invention with at least one fixed filter / Linsenaufhahmeelement and a substantially opposite this Edge of the opening movable FI ter / lens receiving element is provided. By providing on the one hand the at least one fixed filter / lens receiving element fixed on the screen and on the other hand the filter / lens receiving element movable beyond the edge of the opening, the insertion or removal of a respective filter or lens is conceivably simple. For each manipulation, the movable filter / Linseneaufnahmeelement is brought into a projecting beyond the edge of the opening position, whereby the currently held filter or the currently held lens simply with the fingers on the edges of the same grab and remove it from the holder, or . vice versa. Once the desired replacement has taken place, the movable filter / lens display element is simply returned to its position not projecting beyond the edge of the aperture whereby the edge of the filter or lens also comes within the aperture of the screen.
Der Lampenschirm kann sich weiterhin dadurch auszeichnen, dass das bewegliche FiI- ter/Linsenaufnahmeelement in zumindest zwei Positionen arretierbar ist. Die Arretierung gewährleistet, dass das bewegliche Filter/Linsenaufnahmeelement in definierten Positionen zur Ruhe kommt, ohne dass der Benutzer darauf achten muss, wie weit er das bewegliche FiI- ter/Linsenaufnahmeelement bereits bewegt hat.The lampshade can continue to be characterized in that the movable filter / lens receiving element can be locked in at least two positions. The lock ensures that the moveable filter / lens receiving element settles in defined positions without the user having to be aware of how far he has already moved the moveable fi lter / lens receiving element.
Ebenfalls ist es möglich, dass das zumindest eine feststehende Filter/Linsenaufnahmeelement, welches dem beweglichen Filter/Linsenaufnahmeelement gegenüberliegend angeordnet ist, elastisch ist, um den Vorgang des Einsetzens und/oder Herausnehmens der austauschbaren Filter/Linsen weiter zu vereinfachen.Also, it is possible that the at least one fixed filter / lens receiving member, which is disposed opposite to the movable filter / lens receiving member, is elastic to further facilitate the operation of inserting and / or removing the replaceable filters / lenses.
Vorteilhaft kann es weiterhin sein, wenn das bewegliche Filter/Linsenaufnahmeelement mit Rasteinrichtungen zur Arretierung in den zumindest zwei Positionen versehen ist, so dass die Arretierung im Wesentlichen selbständig erfolgt. Die Rastemrichtung kann dabei aus einem mit zumindest einer Ausnehmung an dem Filter/Linsenaufnahmeelement zusammenwirkenden, an dem Lampenschirm fixierten, elastischen Umschlingungsdraht gebildet sein. Alternativ kann die Rasteinrichtung aber auch aus einer mit zumindest einer Ausnehmung an dem Filter/Linsenaufnahmeelement zusammenwirkenden, an dem Lampenschirm gelagerten Federkugel gebildet sein. Schließlich kann die Rasteinrichtung aber auch aus einer das Filter/Linsenaufnahmeelement in Richtung über die Öffnung des Lampenschirms hinaus vorspannenden Feder sowie zumindest einer mit zumindest einer Ausnehmung an dem Filter/Linsenaufnahmeelement zusammenwirkenden Klinkeneinrichtung gebildet sein.It may also be advantageous if the movable filter / lens receiving element is provided with locking devices for locking in the at least two positions, so that the Locking essentially independent. The Rastemrichtung can be formed from a cooperating with at least one recess on the filter / lens receiving element, fixed to the lampshade, elastic wrapping wire. Alternatively, however, the latching device can also be formed from a spring ball cooperating with at least one recess on the filter / lens receiving element and mounted on the lampshade. Finally, however, the latching device can also be formed from a spring biasing the filter / lens receiving element in the direction beyond the opening of the lampshade and at least one latching device cooperating with at least one recess on the filter / lens receiving element.
Weiterhin kann es von Vorteil sein, dass das Filter/Linsenaufnahmeelement ein in einer entsprechenden Buchse geführter Stift ist, der zur Halterung des Filter/Linse mit einer zumindest der Stärke der Filters/Linse entsprechenden Nut versehen ist in die der Rand des Filters bzw. der Linse eingesetzt wird. Von besonderem Vorteil ist es dabei, wenn der Stift ein rotations- symmetrischer Bolzen ist, dessen die Nut zur Aufnahme des Filters/Linse sowie die zumindest eine Ausnehmung zur Arretierung als umlaufende Nuten ausgebildet sind.Furthermore, it may be advantageous that the filter / lens receiving element is a guided in a corresponding socket pin which is provided for holding the filter / lens with a groove at least equal to the thickness of the filter / lens corresponding groove in the edge of the filter or the Lens is used. It is particularly advantageous if the pin is a rotationally symmetrical pin whose groove for receiving the filter / lens and the at least one recess for locking are formed as circumferential grooves.
Schließlich ist es von Vorteil, wenn zwei feststehende Filter/Linsenaufnahmeelemente vorgesehen sind, so dass sich zusammen mit dem beweglichen Filter/Linsenaufnahmeelement eine Dreipunkthalterung ergibt, die den Filter bzw. die Linse entsprechend stabilisiert.Finally, it is advantageous if two fixed filter / lens receiving elements are provided, so that together with the movable filter / lens receiving element results in a three-point mount, which stabilizes the filter or the lens accordingly.
Natürlich besteht die Möglichkeit, dass der Lampenschirm anstelle von einer z.B. mit zwei gegenüberliegenden Öffnungen zur jeweiligen austauschbaren Anordnung eines Filters/Linse versehen ist, wobei dann für jede der Öffnungen entsprechende Filter- /Linsenaufnahmeelemente vorgesehen sind. Es ist bei dieser Ausführungsform bevorzugt, dass die jeweiligen Filter-/Linsenaufnahmeelemente der zwei Öffnungen als ein einzelnes, wechselweise über den jeweiligen Rand der Öffnung hinausbewegliches, integrales Bauteil ausgebildet sind, welches in zumindest drei Positionen entsprechend den obigen Ausführungen arretierbar ist.Of course, there is the possibility that the lampshade instead of a e.g. is provided with two opposite openings for each interchangeable arrangement of a filter / lens, then for each of the openings corresponding filter / lens receiving elements are provided. It is preferred in this embodiment that the respective filter / lens receiving elements of the two openings are formed as a single, alternately movable beyond the respective edge of the opening, integral component, which is lockable in at least three positions according to the above embodiments.
Weitere Eigenschaften und Vorteile ergeben sich aus der folgenden Beschreibung einer lediglich beispielhaften bevorzugten Ausführungsform unter Bezugnahme auf die beigefügten Zeichnungen. Darin zeigt: Fig. 1 eine dreidimensionale Ansicht eines Lampenschirm mit festen und beweglichen Filter/Linsenaufnahmeelementen sowie ein Filterelement in Explosionsansicht;Further characteristics and advantages will become apparent from the following description of a merely exemplary preferred embodiment with reference to the accompanying drawings. It shows: Figure 1 is a three-dimensional view of a lampshade with fixed and movable filter / lens receiving elements and a filter element in exploded view.

Die Figur 1 zeigt eine dreidimensionale Ansicht eines Lampenschirm mit einem Schirmkör- per 2, der zumindest eine Öffnung 4 zur austauschbaren Anordnung eines Filters/Linse 6 aufweist, wobei der Schirmkörper 2 mit zwei feststehenden Filter/Linsenaufnahmeelement 8 und einem diesem im wesentlichen gegenüberliegenden über den Rand der Öffnung 4 hinausbeweglichen Filter/Linsenaufnahmeelement 10 versehen ist. Durch das Vorsehen einerseits der am Schirm 2 fixierten, feststehenden Filter-/Linsenaufnahmeelemente 8 und andererseits des über den Rand der Öffnung hinausbeweglichen Filter-/Linsenaufnahmeelements 10 gestaltet sich das Einsetzen bzw. Herausnehmen eines jeweiligen Filters oder einer Linse als denkbar einfach, wie weiter unten noch näher erläutert werden soll.FIG. 1 shows a three-dimensional view of a lampshade having a screen body 2 which has at least one opening 4 for interchangeable arrangement of a filter / lens 6, the screen body 2 having two fixed filters / lens receiving elements 8 and a substantially opposite one Edge of the opening 4 movable filter / lens receiving element 10 is provided. By providing on the one hand the fixed on the screen 2, fixed filter / lens receiving elements 8 and on the other hand beyond the edge of the opening movable Filter- / Linsenaufnahmeelements 10, the insertion or removal of a respective filter or lens designed as simple as possible, as below will be explained in more detail.
Wie der Figur 1 ohne weiteres zu entnehmen ist, ist der Schirm 2 nach Maßgabe der vorlie- genden Ausführungsform im wesentlichen tonnenförmig und weist zwei gegenüberliegende Öffnungen 4 auf, in denen jeweils ein Filter 6 angeordnet werden kann.As can be seen in FIG. 1, the screen 2 is essentially barrel-shaped in accordance with the present embodiment and has two opposite openings 4, in each of which a filter 6 can be arranged.
Der Schirm 2 ist im Inneren mit zwei Querverstrebungen 2a versehen sowie mit einem Steckelement 2b, durch welches eine Leuchtmittel (nicht gezeigt) eingeführt und fixiert werden kann. Zur Manipulation ist darüber hinaus ein Griff 2c vorgesehen.The screen 2 is internally provided with two cross braces 2a and with a plug element 2b, through which a light source (not shown) can be inserted and fixed. For manipulation beyond a handle 2c is provided.
Die feststehenden Aufnahmeelemente sind nach Maßgabe der vorliegenden Erfindung jeweils aus einem Federstahlblech geformt und mittels jeweils einer Schraube oder Niete 8a an dem Schirm 2 in einer Art und Weise fixiert, dies den freien Enden erlaubt, zu federn. Zur Aufnahme und Halterung des jeweiligen Filters 6 ist in den Halteelementen 8 jeweils eine Nut 8b ausgebildet, in die der Rand des Filters oder der Linse eingeführt werden kann, wie weiter unten beschrieben wird.The fixed receiving elements are formed in accordance with the present invention each of a spring steel sheet and by means of a respective screw or rivet 8 a on the Fixed screen 2 in a manner that allows the free ends to spring. For receiving and holding the respective filter 6, a groove 8b is respectively formed in the holding elements 8, into which the edge of the filter or the lens can be inserted, as will be described below.
Das bewegliche Filter/Linsenaufnahmeelement 10 ist nach Maßgabe der gezeigten Ausführungsform in drei Positionen arretierbar, wobei die Arretierung gewährleistet, dass das bewegliche Filter/Linsenaufnahmeelement 10 in definierten Positionen zur Ruhe kommt, ohne dass der Benutzer darauf achten muss, wie weit er das bewegliche Filter/Linsenaufnahmeelement 10 bereits bewegt hat.The movable filter / lens receiving element 10 is lockable in three positions according to the embodiment shown, the locking ensuring that the movable filter / lens receiving element 10 comes to rest in defined positions, without the user having to pay attention to how far he the movable filter / Lens receiving element 10 has already moved.
Nach Maßgabe der gezeigten Ausführungsform ist das bewegliche Filter/Linsenaufnahmeelement 10 mit Rasteinrichtungen zur Arretierung in den drei Positionen versehen, so dass die Arretierung im Wesentlichen selbständig erfolgt. Die Rasteinrichtung besteht dabei aus einem mit einer (nicht gezeigten) Ausnehmung an dem Filter/Linsenaufnahmeelement 10 zusammenwirkenden, an dem Schirm 2 fixierten, elastischen (nicht gezeigten) Umschlingungsdraht. Alternativ kann die Rasteinrichtung aber auch aus einer mit zumindest einer Ausnehmung an dem Filter/Linsenaufnahmeelement zusammenwirkenden, an dem Lampenschirm gelagerten Federkugel gebildet sein. Schließlich kann die Rasteinrichtung aber auch aus einer das Filter/Linsenaufnahmeelement in Richtung über die Öffnung des Lampenschirms hinaus vorspannenden Feder sowie zumindest einer mit zumindest einer Ausnehmung an dem Filter/Linsenaufnahmeelement zusammenwirkenden Klinkeneinrichtung gebildet sein, ähnlich dem Mechanismus eines Kugelschreibers.According to the embodiment shown, the movable filter / lens receiving element 10 is provided with locking means for locking in the three positions, so that the locking is substantially independent. The latching device consists of a (not shown) with a recess (not shown) on the filter / lens receiving element 10 cooperating, fixed to the screen 2, elastic (not shown) looping wire. Alternatively, however, the latching device can also be formed from a spring ball cooperating with at least one recess on the filter / lens receiving element and mounted on the lampshade. Finally, however, the latching device can also be formed from a spring biasing the filter / lens receiving element in the direction beyond the opening of the lampshade and at least one latching device cooperating with at least one recess on the filter / lens receiving element, similar to the mechanism of a ballpoint pen.
Das Filter/Linsenaufnahmeelement 10 ist nach Maßgabe der gezeigten Ausführungsform ein in einer Buchse 12 geführter Stift, der zur Halterung der Filter/Linse 6 mit zwei der Stärke der Filters/Linse entsprechenden Nuten 14 versehen ist in die der Rand des Filters bzw. der Linse 6 eingesetzt wird.The filter / lens receiving element 10 is, according to the embodiment shown, a guided in a bush 12 pin which is provided for holding the filter / lens 6 with two of the thickness of the filter / lens corresponding grooves 14 in the edge of the filter or the lens 6 is used.
Aus der Figur 2 ergibt sich der Lampenschirm nach Maßgabe der Figur 1, jedoch mit eingesetzten Filter 6 und einem zusätzlichen Linsenelement 6a, wobei gleiche Elemente mit gleichen Bezugszeichen versehen sind. Weiterhin zeigt die Figur 2 ein eingesetztes Leuchtmittel 16 und den Ansatz eines Ständers 18, auf den der Lampenschirm aufgesteckt ist. Die Figur 3 zeigt den Querschnitt der Fig. 3, wobei das bewegliche Halteelement jedoch nach unten über den Rand der Öffnung 4 hinausbewegt wurde, so dass der Rand des Filters 6 außerhalb der Öffnung 4 des Schirmes 2 liegt und leicht gegriffen werden kann und, wie sich aus Fig. 4 ergibt, aus der Nut 14 des beweglichen Halteelementes 10 herausgenommen werden kann.From Figure 2, the lampshade results in accordance with the figure 1, but with inserted filter 6 and an additional lens element 6a, wherein like elements are provided with the same reference numerals.
