Description
Die Erfindung bezieht sich auf eine Lampenfassung, insbesondere für Halogen-Reflektorlampen, mit einem aus Isolierstoff bestehenden Fassungskörper und einer mit diesem verrastbaren Haltefeder für die in die Fassung eingesteckte Lampe, wobei die Haltefeder ein im wesentliches ringförmiges, am Fassungskörper anlegbares Zentralstück aufweist, zu dessen einer Seite, jeweils paarig, zwei Federschenkel zum Angriff am Lampensockel und zu dessen anderer Seite zwei Rastschenkel zur Festlegung der Haltefeder am Fassungskörper angeordnet sind.The invention relates to a lamp holder, especially for halogen reflector lamps, with one out Insulating socket body and one with this lockable retaining spring for the in the socket inserted lamp, the retaining spring being essentially one ring-shaped central piece that can be placed on the socket body on one side, in pairs, two spring legs to attack the lamp base and to the other side of two locking legs for fixing the retaining spring arranged on the socket body are.
Die Erfindung geht insbesondere von Lampenfassungen der Typenreihen GU4 und GU5,3 aus. Solche Fassungen in Form von zylindrischen Körpern sind relativ klein und weisen einen Außendurchmesser von etwa 17 mm und eine Höhe von 9,5 mm auf. Sie beinhalten die Kontakte zur elektrischen Verbindung der einzusteckenden Leiter mit den Lampenkontaktstiften und in einem Stichmaß von ca. 12 mm Durchgangslöcher für Befestigungsorgane wie Schrauben oder Nieten, mit denen die Fassung an einem Fassungsträger, z.B. einem Leuchtenblech, befestigt werden kann. Reflektorlampen, das sind gesockelte Halogenlampen mit einem fest angebrachten Reflektor, müssen besonders an der Fassung gehalten werden, wozu die im Querschnitt im wesentlichen U-förmig angeordneten Haltefedern dienen. Eine solche Feder weist außerdem ein zentrales, am Fassungskörper anlegbares Zentralstück auf und Mittel zur Befestigung der Haltefeder am Fassungskörper. The invention relates in particular to lamp holders of the type series GU4 and GU5,3. Such versions in the form of cylindrical bodies are relatively small and have an outer diameter of about 17 mm and a height of 9.5 mm. They include the contacts for the electrical connection of the conductors to be inserted with the lamp contact pins and in a gauge of approx. 12 mm through holes for fasteners such as Screws or rivets with which the socket on one Holder, e.g. a light plate attached can be. Reflector lamps are socketed halogen lamps with a fixed reflector be kept especially on the version, for which the in Cross-section arranged essentially U-shaped retaining springs serve. Such a spring also has central central piece that can be placed on the socket body on and means for attaching the retaining spring to the socket body.
Bei einer älteren vorbekannten Ausführung untergreift das Zentralstück der Haltefeder, welches zugleich den Steg des im wesentlichen U-förmigen Bauteils ausbildet, den Fassungskörper und ist im Bereich der Durchgangslöcher für die Befestigungsmittel mit dem Fassungskörper vernietet. Diese Ausführung hat den Nachteil, daß - bei Betrachtung senkrecht von oben - die im Querschnitt V-förmig ausgeprägten Haltefederschenkel die Durchgangslöcher größtenteils verdecken. Wenn also eine solche Fassung mit daran fest angebrachten Haltefedern montiert werden soll, ist die Montage einerseits umständlich, weil zum Einbringen und Betätigen der Befestigungsmittel die Haltefederschenkel gespreizt werden müssen; zum anderen können diese bei einer solchen Manipulation auch verbogen und mithin beschädigt werden.In the case of an older, previously known version the center piece of the retaining spring, which at the same time the web of the essentially U-shaped component trains the socket body and is in the area the through holes for the fasteners with the Frame body riveted. This version has the Disadvantage that - when viewed vertically from above - the V-shaped retaining spring legs cover most of the through holes. So if such a version with firmly attached to it Retaining springs to be installed is the assembly cumbersome on the one hand, because it can be inserted and operated the fastening means the retaining spring legs need to be spread; on the other hand, these can such manipulation also bent and therefore to be damaged.
Bei einer verbesserten Ausführungsform, von der die Erfindung ausgeht, ist das Zentralstück der Haltefeder von der Rückseite der Fassung her auf einen Fortsatz derselben aufpreßbar, und auf der von den Haltefederschenkeln wegweisenden Seite des Zentralstücks sind aus ihm widerhakenartige Rastschenkel ausgeformt, die sich bei Erreichen der bestimmungsgemäßen Lage jeweils gegen eine Stützschulter an der Außenseite des Fassungskörpers einrastend abstützen. Die zur Befestigung der Fassung erforderlichen Durchgangslöcher sind in einer Ebene zwischen den Federschenkeln der Haltefeder und derart nach außen versetzt angeordnet, daß sie von den Haltefedern nicht mehr übergedeckt werden. Hierbei handelt es sich allerdings um eine besondere Bauform des Fassungskörpers. Im Unterschied dazu sind bei den üblichen bekannten Fassungen der eingangs genannten Dimension die Durchgangslöcher in den im wesentlichen kreisförmigen Umriß des Fassungskörpers integriert und würden auch von der zuletzt beschriebenen Haltefeder abgedeckt.In an improved embodiment, of which the invention is based, is the centerpiece of the retaining spring from the back of the frame onto an extension the same can be pressed on, and on the holding spring legs groundbreaking side of the centerpiece barbed locking legs formed from it, the each time when the intended position is reached against a support shoulder on the outside of the socket body support in a snap. The one for attachment through holes required are in a plane between the spring legs of the retaining spring and arranged so outwardly that they are from the retaining springs are no longer covered. Here however, it is a special design of the socket body. In contrast, the usual known versions of the aforementioned Dimension the through holes in the main integrated circular outline of the socket body and would also from the last described spring covered.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Lampenfassung der im Oberbegriff des Anspruchs 1 näher umrissenen Art verfügbar zu machen, die hinsichtlich Ausbildung und Anordnung der Haltefeder insbesondere so geschickt ausgebildet ist, daß einerseits ein Fassungskörper grundsätzlich üblicher Bauform verwendet werden kann und andererseits die Befestigungsdurchbrüche des Fassungskörpers wenigstens bei der Montage und ggf. zur Demontage der Fassung vollkommen frei zugänglich sind.The invention is therefore based on the object a lamp holder in the preamble of claim 1 to make the more outlined type available in terms of Formation and arrangement of the retaining spring in particular is so skillfully trained that on the one hand Socket body generally used conventional design can be and on the other hand the fastening breakthroughs of the socket body at least during assembly and, if necessary, completely free to dismantle the frame are accessible.
Die Erfindung löst diese Aufgabe durch die Merkmale des Anspruchs 1. Sie ist demnach insbesondere dadurch gekennzeichnet, daß die Rastschenkel in axialer Richtung der Federschenkel, also im jeweils gleichen Umfangsbereich des Zentralstücks, angeordnet sind und daß das Zentralstück eine Biegefeder ausbildet, über die die Rastschenkel durch Zusammendrücken der Federschenkel spreizbar sind bzw. ihre Haltekräfte am Fassungskörper erhöhen, wenn die Federschenkel auf Spreizung belastet sind.The invention solves this problem by the features of claim 1. It is therefore special characterized in that the locking leg in the axial Direction of the spring legs, so in the same Circumferential area of the central piece, are arranged and that the center piece forms a spiral spring, via the locking legs by compressing the spring legs are spreadable or their holding forces on the socket body increase when the spring legs on spread are burdened.
Zufolge der Erfindung kann die Haltefeder erst nach der Montage der Fassung am Fassungsträger auf den Fassungskörper aufgerastet werden. Dies gestaltet sich vor allem deshalb besonders einfach, weil die Haltefeder in einer Formgestaltung vorliegt, die im weitesten Sinne mit derjenigen einer Wäscheklammer vergleichbar ist. Dabei kommt dem ringförmigen Zentralstück die Bedeutung der Wickelfeder der Wäscheklammer zu, die Griffschenkel werden von den Federschenkeln der Haltefeder ausgebildet und die Greif- oder Klemmschenkel von den Rastschenkeln, mit denen die Haltefeder am Fassungskörper festgelegt wird.According to the invention, the retaining spring can only after mounting the frame on the frame carrier on the Socket body can be snapped on. This turns out especially easy because the retaining spring is in a design that is the broadest Senses comparable to that of a clothespin is. This comes the ring-shaped central piece Importance of the clock spring to the clothespin too Handle legs are from the spring legs of the retaining spring trained and the gripping or clamping legs of the locking legs with which the retaining spring on the socket body is set.
Zum Anbringen der Haltefeder an den - bereits montierten - Fassungskörper brauchen die Federschenkel lediglich zwischen Daumen und Zeigefinger zusammengedrückt zu werden und die Haltefeder mit dem Zentralstück auf die Sichtfläche des Fassungskörpers gesetzt zu werden. Läßt man die Klammer dann los, greifen die Rastschenkel automatisch am Fassungskörper ein. Bei Bedarf kann die Haltefeder wieder abgenommen werden wie eine Wäscheklammer von der Leine.To attach the retaining spring to the - already assembled - Socket bodies need the spring legs just squeezed between thumb and forefinger to become and the retaining spring with the center piece placed on the visible surface of the socket body to become. If you then let go of the clip, they grip Locking leg automatically on the socket body. At If necessary, the retaining spring can be removed again a clothespin on a leash.
Die Erfindung bietet insoweit einen besonderen Vorteil, als aufgrund der Spreizung der Federschenkel der Haltefeder durch die in die Fassung eingesetzte Lampe die Rastschenkel umso stärker gegen den Fassungskörper gepreßt werden, je stärker die Lampe die Federschenkel auseinanderspreizt. Federschenkel und Rastschenkel unterstützen sich nämlich in vorteilhafter Weise hinsichtlich ihrer Kraftentfaltung gegenseitig.In this respect, the invention offers a special one Advantage than due to the spread of the spring legs the retaining spring by the inserted in the socket Lamp the locking legs all the more against the socket body be pressed, the stronger the lamp the spring legs spreads apart. Spring legs and locking legs support each other in advantageous Mutual in terms of their power.
Weiterhin ergibt sich durch das wesentliche Erfindungsmerkmal, wonach die Rastschenkel in axialer Richtung der Federschenkel angeordnet sind, also im jeweils gleichen Umfangsbereich des Zentralstücks, der Vorteil, daß axial gerichtete Zugkräfte an der Lampe unmittelbar in die Rastschenkel übergeleitet werden, so daß dabei ein Durchbiegen des Zentralstücks ausgeschlossen und die Verbindung am Fassungskörper somit besonders fest und stabil ist.Furthermore, due to the essential feature of the invention, after which the locking legs in the axial direction the spring legs are arranged, so in each case same circumferential area of the centerpiece, the advantage that axially directed tensile forces on the lamp immediately be transferred into the locking leg, so that it a deflection of the central piece is excluded and the connection on the socket body is particularly strong and is stable.
Zu erwähnen ist noch eine weitere, gleichfalls offenkundig vorbenutzte Halogenlampen-Fassung, bei der auch schon eine separat von außen an den Fassungskörper ansteckbare Haltefeder vorgesehen ist, die ebenfalls ein ringförmiges Zentralstück aufweist, von denen sich zur einen Seite hin die beiden Federschenkel und zur anderen Seite hin die beiden Rastschenkel erstrecken. Allerdings liegen hier Federschenkel und Rastschenkel nicht in demselben schmalen Umfangsbereich, also nicht gewissermaßen 'in Linie', sondern sie sind paarig um jeweils etwa 90o zueinander versetzt. Deshalb hat das Spreizen oder Zusammendrücken der Federschenkel und/oder der Rastschenkel keinerlei günstigen Einfluß auf eine optimale Kraftentfaltung. Hier können sich die Kraftwirkungen gegenseitig nicht ergänzen. Ein etwa loser, zum Wackeln neigender Sitz der Rastschenkel am Fassungskörper wird auch nach dem Einstecken der Lampe zwischen die Federschenkel nicht verbessert. Bei Zug an der Lampe übertragen sich die Zugkräfte zunächst auf das Zentralstück, ehe sie von dort in die Rastschenkel eingeleitet werden. Dies hat in nachteiliger Weise zur Folge, daß solche Zugkräfte zum Durchbiegen des Zentralstücks führen. Außerdem läßt sich die Haltefeder auch nicht auf die aus der Erfindung resultierende einfache Art und Weise montieren und noch schwieriger wieder vom Fassungskörper abnehmen.Also worth mentioning is another halogen lamp socket that is also obviously used, in which a retaining spring that can be plugged in separately from the outside of the socket body is also provided, which also has an annular central piece, of which the two spring legs are on one side and the other Extend the two locking legs towards the side. However, the spring legs and locking legs are not in the same narrow circumferential area, that is to say not 'in line' to a certain extent, but are offset in pairs by about 90 ° each. For this reason, the spreading or compression of the spring legs and / or the latching legs has no favorable influence on optimal power delivery. Here the effects of force cannot complement each other. An approximately loose, wobbling seat of the locking legs on the socket body is not improved even after inserting the lamp between the spring legs. When pulling on the lamp, the tensile forces are first transferred to the central piece before they are introduced from there into the locking legs. This has the disadvantageous consequence that such tensile forces lead to the deflection of the central piece. In addition, the retaining spring can not be assembled in the simple manner resulting from the invention and can be removed from the socket body even more difficult.
Von besonderer Bedeutung ist ein weiteres Merkmal der Erfindung mit selbständiger Bedeutung, welches darin besteht, daß das ringförmige Zentralstück unter Belassung des Materials für die Rastschenkel aus einem Materialstreifen ausgeschnitten ist und daß durch im wesentlichen sekantial gerichtete Einschnitte die Länge der Rastzungen und ihre Anbindung an den Peripheriebereich des Zentralstücks festgelegt ist. Durch diese besondere Schnittführung beim Ausstanzen der Haltefeder aus dem Blech-Materialstreifen wird ungewöhnlich sparsam mit dem Ausgangswerkstoff umgegangen. Zur Ausbildung der Rastzungen wird in vollem Umfange nur von demjenigen Abschnitt des Materialstreifens Gebrauch gemacht, aus dem der zentrale Durchbruch des ringförmigen Zentralstücks gefertigt wird. Dadurch fällt äußerst wenig Schnittabfall an, und der Blechstreifen, aus dem die Haltefeder erzeugt wird, kann sehr schmal sein. Bei dem zuletzt in Bezug genommenen Stand der Technik erstrecken sich demgegenüber bezüglich des ringförmigen Zentralstücks alle vier Schenkel, nämlich die zwei Federschenkel und die zwei Rastschenkel, in vier unterschiedliche Richtungen strahlenförmig nach außen. Die mittige Öffnung des ringförmigen Zentralstücks wird als solche vollständig ausgeschnitten. Zwischen den strahlenförmig nach außen weisenden Fortsätzen ergeben sich große Abfallstücke, und der Ausgangs-Blechstreifen, aus dem der Rohling ausgestanzt wird, muß erheblich breiter sein.Another feature is of particular importance of the invention with independent meaning, which is that the ring-shaped central piece under Leave the material for the locking legs from one Material strips is cut out and that by im essential secant incisions the length the locking tongues and their connection to the peripheral area of the centerpiece is fixed. Through this special cut when punching out the retaining spring the sheet of metal material becomes unusually economical dealt with the starting material. For training the locking tongues are only used in full that section of the strip of material made from the central breakthrough of the annular Center piece is manufactured. It falls extremely little cutting waste and the metal strip from which the retaining spring is generated can be very narrow. At the latest state of the art in contrast, extend with respect to the annular Center piece all four legs, namely the two Spring legs and the two locking legs, in four different Directions radiating outwards. The central opening of the annular center piece is called such completely cut out. Between the rays outward-looking extensions result large pieces of waste, and the exit sheet metal strip the blank is punched out must be considerably wider his.

jedoch in die entgegengesetzte Richtung erstrecken.

einen um etwa 90° nach einwärts umgebogenen Rasthaken

Wie man sich bei Betrachtung der Fig. 1 leicht
vorstellen kann, bildet die Haltefeder 12 aufgrund der
beschriebenen und dargestellten Geometrie eine Doppelschenkel-Klammer
aus, deren Prinzip in etwa mit dem
einer Wäscheklammer vergleichbar ist. Das ringförmige
Zentralstück 15, an dessen Peripherie 21 alle vier Zungen
16 und 18 wurzeln, bildet eine Biegefeder aus mit
dem Effekt, daß, wenn die Federschenkel 16 aufeinanderzu
bewegt werden, sich die Rastschenkel 18 spreizen
und umgekehrt. Deshalb ist es sehr einfach, die Haltefeder
12 auf die bereits montierte Lampenfassung 11
aufzusetzen. Hierzu drückt man die beiden Federschenkel
16 zusammen und setzt die Haltefeder auf den Fassungskörper,
bis das ringförmige Zentralstück 15 auf ihm
aufsitzt. Dann läßt man die Federschenkel 16 los, und

also the considerable advantage that, if due to the

der dargestellten Ausführungsform besteht ferner darin,
daß die Rastschenkel 18 mit ihren Rasthaken 19 vollkommen
