Description
Die Erfindung betrifft eine Pendelleuchte mit Zugmittelantrieb
gemäß dem Oberbegriff des Anspruches
1.The invention relates to a pendant lamp with traction drive
according to the preamble of the
Pendelleuchten mit Zugmittelantrieb ermöglichen die Einstellung verschiedener Höhen ihrer Leuchten durch eine in der Aufhängung des Zugmittels angeordnete Mechanik. Erfindungsgemäß handelt es sich hierbei bevorzugt um ein Federwerk, bei dem die Trommelachse mit einer Spiralfeder derart verbunden ist, daß beim Abwickeln des Zugmittels die Trommel die Feder aufzieht, wobei z.B. eine über einen Freilauf wirkende Bremse einfällt, sobald die zum Aufziehen der Feder notwendige Zugkraft aufhört. Diese Bremse ließe sich dann lösen, wenn erneut gezogen wird, wodurch sich dann das Zugmittel durch die Kraft der Feder auf die Trommel aufwickelt. Die Pendelleuchte läßt sich aber auch so einstellen, daß das Gewicht des freien Endes des Zugmittels und der daran hängenden Leuchte ausreicht, um die Leuchte in einer vorgegebenen Position zu halten, aber das Zugmittel aufwickelt, wenn die Leuchte angehoben wird.Pendant lights with traction drive enable the Setting different heights of your lights by one arranged in the suspension of the traction device Mechanics. According to the invention preferably a spring mechanism in which the Drum axis connected with a coil spring in this way is that when unwinding the traction device, the drum the spring winds up, e.g. one over one Free-running brake engages as soon as the Winding the spring stops the necessary tensile force. This brake could be released when pulled again , which then pulls through the force of the spring is wound on the drum. The Pendant lamp can also be set so that the weight of the free end of the traction device and the attached lamp is sufficient to the To hold the lamp in a predetermined position, but the traction device winds up when the lamp is raised becomes.
Als Zugmittel kann erfindungsgemäß Textil ummanteltes und deswegen relativ dickes und weiches Kabel verwendet werden. Vorzugsweise ist die Erfindung jedoch auf Kabel anwendbar, die dem modernen Standard entsprechen und einen homogenen, vorzugsweise aus Kunststoff gefertigten Mantel aufweisen, der das Kabel gegen Verschleiß besser schützt, jedoch dessen Flexibilität mehr oder weniger stark herabsetzt. Solche Zugmittel sind in der Regel auch dünner als Textil ummantelte Leitungskabel. Für die Erfindung eignen sich letztlich auch Zugmittel, welche nicht als elektrische Zuleitungen verwendet werden, sondern mit einer meistens aus einem Kunststoff ummantelten Kabel bestehenden elektrischen Zuleitung zusammenwirken, bei der das Kabel mit vorgeformten Windungen das Zugmittel als Spirale umgibt.According to the invention, textile coated can be used as the traction means and therefore relatively thick and soft cable be used. The invention is preferred however applicable to cables that meet the modern standard correspond and a homogeneous, preferably have made of plastic, the better protects the cable against wear, however whose flexibility more or less diminishes. Such traction devices are usually thinner cable covered as textile. For the In the end, pulling means are also suitable according to the invention, which are not used as electrical leads but mostly with a plastic sheathed cables existing electrical Interact supply line, in which the cable with preformed turns the traction device as a spiral surrounds.
In der Praxis zeigt sich, daß bislang die für die erfindungsgemäß, insbesondere wie oben beschrieben ausgebildeten Aufroll- und Abrollmechaniken benutzbaren Zugmittel am wenigsten geeignet sind, wenn sie ein vergleichsweise dünnes, aber steifes, d.h. unflexibles, im Querschnitt im wesentlichen zylindrisches Gebilde darstellen, was hauptsächlich auf die beschriebenen Kunststoff ummantelten Leitungskabel zutrifft. Es zeigt sich dann, daß die Mechanik, d.h. insbesondere beim Abziehen des Zugmittels von der Trommel beim Absenken der Leuchte zunehmend rauher und holpriger läuft. Dadurch leidet der Bedienungskomfort der Pendelleuchte erheblich und nicht selten versagt die Mechanik, die dann durch Entwirren des Zugmittels auf der Trommel wieder in Ordnung gebracht werden muß, was Laien häufig unmöglich ist. Solche Nachteile treten, wenn auch weniger häufig, auch beim Anheben der Leuchte während des Aufwickelns des Zugmittels auf die Trommel auf. In practice it has been shown that so far for according to the invention, in particular as described above trained roll-up and roll-off mechanisms usable Traction devices are the least suitable if it is a comparatively thin but stiff, i.e. inflexible, essentially cylindrical in cross section Structures represent what is mainly on the described plastic-coated cable applies. It then turns out that the mechanics, i.e. especially when pulling the traction device increasingly from the drum when lowering the lamp runs rough and bumpy. As a result, ease of use suffers the pendant lamp considerably and it is not uncommon for the mechanics to fail due to this Untangle the traction device on the drum again It needs to be put in order, which is often impossible for laypeople is. Such disadvantages occur, albeit less often, even when lifting the lamp during the winding of the traction device on the drum.
Aus DE-C-149 954 ist eine Pendelleuchte mit Zugmittelantrieb durch eine Trommel bekannt, wobei die Trommel eine konische Grundgestalt aufweist und an ihrem Außenmantel mit einer schneckenförmig gewundenen Nut versehen ist. Ein geordnetes Aufwickeln des Zugmittels auf der Trommel soll durch die schneckenförmig gewundene Nut gewährleistet sein, in welcher das ansonsten ungeführte Zugmittel bei ordnungsgemäßer Betätigung sich ebenfalls schneckenförmig aufrollt. Die konische Grundgestalt der Trommel ist vorgesehen, um ein sich änderndes Drehmoment einer die Trommel antreibenden Federeinrichtung zu kompensieren.From DE-C-149 954 is a pendant lamp with traction drive by a Known drum, wherein the drum has a conical basic shape and provided with a spiral-shaped groove on its outer casing is. An orderly winding of the traction device on the drum should by spiral-shaped groove can be guaranteed, in which otherwise unguided traction means, if properly operated, also become helical rolls up. The conical basic shape of the drum is intended to be a changing torque of a spring device driving the drum to compensate.
Aus EP-A-054 629 7 ist weiterhin eine Vorrichtung zum Aufwickeln eines Seiles auf einer geringfügig konischen Wickeltrommel bekannt, auf welcher das Seil in mehreren Lagen übereinander zur Anordnung kommt. Diese Vorrichtung weist ferner eine Führung auf, welche eine Bewegung des Seils in Axialrichtung des Trommelmantels über deren gesamten axialen Länge erlaubt. Das Seil ist somit in Axialrichtung der Trommel nicht geführt.From EP-A-054 629 7 there is also a device for winding a rope known on a slightly conical winding drum on which the rope in several layers are arranged one above the other. This device exhibits also a guide on which a movement of the rope in the axial direction of the Drum shell allowed over its entire axial length. The rope is thus not guided in the axial direction of the drum.
Es ist eine Aufgabe der vorliegenden Erfindung, eine Pendelleuchte mit Zugmittelantrieb durch eine Trommel bereitzustellen, wobei ein geordnetes Aufwickeln des Zugmittels auf der Trommel unterstützt wird.It is an object of the present invention, a pendant lamp with traction drive to be provided by a drum, with orderly winding the traction device is supported on the drum.
Diese Aufgabe wird durch eine Pendelleuchte mit den Merkmalen des Anspruchs
1 gelöst. This task is accomplished by a pendant lamp with the features of the
Gemäß der Erfindung wird durch den konischen Mantel der Trommel aus der sich beim Aufwickeln des Zugmittels auf der Trommel ergebenden Schnürspannung eine Hangabtriebskraft erzeugt, die die Umschläge des Zugmittels um die Trommel entlang der Neigung des Trommelmantels bewegt, bis sie an dem bereits festliegenden Umschlag des Zugmittels zum Stillstand kommen. Diese der Richtung der Hangabtriebskraft folgende Bewegung der Umschläge ist gewollt und wird durch die Abstimmung ihrer Haupteinflußgrößen aufeinander so gewählt, daß die vielen Umschläge auf der Trommel sich sämtlich eng und gleichmäßig aneinanderlegen. Das hat zur Folge, daß benachbarte Umschläge des Zugmittels sich nicht mehr über- oder gar untereinanderlegen können. Dadurch werden der rauhe und holprige Lauf der Mechanik beseitigt und das Zugmittel geschohnt. Insbesondere beim Herabziehen der Leuchte und Abziehen des Zugmittels von der Trommel erhöht sich dadurch der Bedienungskomfort wesentlich und verhindert das Versagen der Mechanik infolge unregelmäßiger Umschläge des Zugmittels um die Trommel.According to the invention, the conical jacket the drum from which when winding the traction device lacing tension on the drum a downhill slope creates the envelopes of traction around the drum along the slope of the drum shell until it already moves on fixed envelope of the traction device to a standstill come. This is the direction of the downforce the following movement of the envelopes is wanted and is by tuning their main influencing factors consecutively chosen so that the many envelopes all tight on the drum and Put them together evenly. This has the consequence that neighboring envelopes of the traction device are not can lay more on top of each other or even one below the other. Thereby become the rough and bumpy run of the mechanics eliminated and the traction device used. In particular when pulling down the lamp and pulling the Traction means from the drum increases the Ease of use is essential and prevents that Mechanical failure due to irregular envelopes of the traction device around the drum.
Die Erfindung hat den Vorteil, daß sie diese vorteilhaften Wirkungen unabhängig von der Art des Zugmittels und seines Aufbaus erzielen und dadurch insbesondere die gewünschten Kunststoffkabel als Zugmittel trotz ihrer Unflexibilität verwenden kann, ohne daß der Bedienungskomfort der Mechanik leidet.The invention has the advantage that it is advantageous Effects regardless of the type of Achieve traction means and its structure and thereby especially the desired plastic cable as Use traction devices despite their inflexibility can without the convenience of the mechanics suffers.
Während sich bei den herkömmlichen textilummantelten
Zugmitteln die beschriebene Bewegung der Umschläge
des Zugmittels auf der Trommel in der Regel
dadurch vollzieht, daß sich das Kabel um sich
selbst dreht und auf dem Trommelmantel abrollt, ist
das bei der von der Erfindung bevorzugten Verwendung
der Kunststoffkabel wegen deren Unflexibilität
nicht der Fall. Dennoch kann die Erfindung mit
ihren Vorteilen auch mit solchen Zugmitteln verwirklicht
werden, was Gegenstand des Anspruches 2
ist. Infolge der vorstehend beschriebenen Abstimmung
der Haupteinflußgrößen aufeinander und der
durch die Zugmittelführung gewährleisteten Ausrichtung
des Zugmittels vor der Trommel gleiten die Umschläge
des Zugmittels auf der Trommelschräge jeweils
bis zur Anlage an den Nachbarumschlag. Dieses
Abrutschen geschieht im wesentlichen ohne Drehung
des Zugmittels um seine Längsachse, was im Ergebnis
ebenfalls den Bedienungskomfort erhöht.While the conventional textile sheathed
Traction means the described movement of the envelopes
of the traction device on the drum as a rule
in that the cable is around itself
itself turns and rolls on the drum jacket, is
the preferred use in the invention
the plastic cable because of its inflexibility
not the case. Nevertheless, the invention can
their advantages also realized with such traction devices
become what is the subject of
Die Erfindung eignet sich in dieser Ausführungsform auch für solche Zugmittel, die von dem eigentlichen Zuleitungskabel wie eingangs beschrieben getrennt sind. Bevorzugt wird die Erfindung jedoch mit den Merkmalen des Anspruches 3 verwirklicht, um dem modernen Standard bei derartigen Pendelleuchten zu entsprechen.The invention is suitable in this embodiment also for traction devices that differ from the actual one Supply cable separated as described at the beginning are. However, the invention is preferred with the Features of claim 3 realized to the modern Standard for such pendant lights too correspond.
Die Erfindung hat auch zur Folge, daß wegen des konischen
Trommelmantels die Umschläge um die kleinen
Trommeldurchmesser geringere Zugmittellängen speichern
als die Umschläge um die größeren Trommeldurchmesser.
Da man übereinanderliegende Umschläge
des Zugmittels auch bei den erfindungsgemäß konischen
Trommelmänteln im Interesse einer leichtgängigen
Aufrollmechanik vermeiden, andererseits aber
die Baugröße der Trommel gering halten sollte, weil
sich die Trommeln sonst nur schwer in der Deckenmontierung
von Pendelleuchten unterbringen lassen,
ist die Ausführungsform nach Anspruch 4 vielfach
vorzuziehen. Hierbei wird nämlich der größere Trommeldurchmesser
im zylindrischen Teil der Trommel
fortgesetzt. Dessen axiale Länge sollte indessen
nur gering sein, um ein Überspringen von Zugmittelumschlägen
zu verhindern. Für solche Ausführungsformen
sind die Merkmale des Anspruches 5 vorgesehen.The invention also has the consequence that because of the conical
Drum envelopes around the little ones
Save the drum diameter of shorter traction lengths
than the envelopes around the larger drum diameters.
Because you have envelopes on top of each other
of the traction means also in the conical according to the invention
Drum coats in the interest of a smooth-running
Avoid retraction mechanism, on the other hand
should keep the size of the drum small, because
the drums are otherwise difficult to mount in the ceiling
can be accommodated by pendant lights,
is the embodiment according to claim 4 many times
preferable. This is because the larger drum diameter
in the cylindrical part of the drum
continued. Its axial length, however, should
only be slight to skip traction envelopes
to prevent. For such embodiments
the features of
Wenn die volle axiale Länge des Trommelmantels zum
Aufwickeln des Zugmittels ausgenutzt werden soll,
was unter den vorgenannten Gesichtspunkten zweckmäßig
ist, muß für den ersten Umschlag des Zugmittels
auf der Trommel ein Widerstand geschaffen werden,
der das Abrollen bzw. Abrutschen des Umschlages
von der Trommel vermeidet. Mit den Merkmalen
des Anspruches 6 wird eine Ausführungsform geschaffen,
bei der dies auf einfache Weise durch einen
Ringflansch verhindert wird, der auch am anderen
Ende der Trommel vorgesehen werden kann. Dadurch
ergibt sich der Vorteil einer vergleichsweise gesteigerten
Formfestigkeit der Trommel. Die beste
Ausnutzung der Trommellänge ergibt sich mit den
Merkmalen des Anspruches 7, weil hierbei bereits
der erste Umschlag des Zugmittels am äußeren, d.h.
am kleineren Ende des Trommelmantels entsteht.If the full axial length of the drum shell to
Winding of the traction device is to be used,
what is expedient from the above points of view
must for the first handling of the traction device
resistance is created on the drum,
the unrolling or slipping of the envelope
avoided from the drum. With the characteristics
