Abstract

A headlamp having a reflector and an opening, situated in the reflector, for accommodating a bulb has a plate-like cap, which bears against the rim of the opening of the reflector and is pressed by a retaining spring, constructed in the shape of a W, against the rim of the opening. The free limbs of the retaining spring are connected to the rim of the opening of the reflector, one limb being connected in a hinged fashion to the reflector, and the other limb having a locking connection to the reflector. The central region of the W shape spans the central contact of the bulb in a contactless fashion. Cut free in each case from the two limbs of the U-shaped central part is a tongue (10) which bears with its free ends (11) under pretension against the plate-shaped cap (4) of the bulb (9). In the installed state, a small gap (16) remains between the bow-shaped transitions (12) to the free limbs (6, 7) and the plate-shaped cap (4) of the bulb (9). <IMAGE>

Description

Die Erfindung betrifft einen Scheinwerfer, mit einem Reflektor und der in dem Reflektor befindlichen Öffnung zur Aufnahme einer Glühlampe, welche einen tellerförmigen Sockel aufweist, der auf dem Öffnungsrand des Reflektors aufliegt und durch eine Haltefeder gegen den Öffnungsrand gepreßt wird, die W-förmig ausgebildet ist und deren freie Schenkel mit dem Öffnungsrand des Reflektors verbunden sind, wobei der eine Schenkel scharnierartig und der andere Schenkel eine Rastverbindung mit dem Reflektor eingeht und der mittlere Bereich der W-Form den Mittenkontakt der Glühlampe berührungslos überspannt.The invention relates to a headlamp, with a reflector and the opening in the reflector for receiving an incandescent lamp, which has a plate-shaped base which rests on the opening edge of the reflector and is pressed against the opening edge by a retaining spring, which is W-shaped and the free legs of which are connected to the opening edge of the reflector, one leg forming a hinge and the other leg engaging with the reflector, and the central region of the W-shape spans the center contact of the incandescent lamp without contact.

Eine derartige Haltefeder ist bereits aus der DE-PS 36 06 538 bekannt. Dabei werden jedoch nicht alle in der Aufgabenstellung vorgeschlagenen Lösungsvorgaben in ausreichendem Maße erfüllt. So ist z. B. ein sicherer Festsitz der Glühlampe im Reflektor dann nicht gewährleistet, wenn ein axialer Druck von hinten auf die Haltefeder wirkt, was auftritt, wenn Leitungen im Scheinwerfergehäuse unkontrolliert liegen und/oder wenn ein relatiy starres Massekabel, welches an dem einen freien Endabschnitt der Haltefeder steckerartig befestigt ist, die Haltefeder aus ihrer Verrastung springen läßt. Es ist also nicht gegeben, daß bei seitlichem Druck, Zugbelastung oder Druck von hinten die Haltefeder in ihrer vorbestimmten Position verbleibt. Außerdem ist es bei der Beschaffenheit der Haltefeder möglich, daß eine Glühlampe mit ihrem Sockel verkantet eingebaut und auch mit der Haltefeder in dieser Stellung verspannt werden kann. Dies ist auf die Länge der Feder, ihrer Biegeform und ihrer relatiy geringen Starrheit zurückzuführen.Such a retaining spring is already known from DE-PS 36 06 538. However, not all proposed solutions proposed in the task are sufficiently fulfilled. So z. B. a secure tight fit of the bulb in the reflector is not guaranteed when an axial pressure acts from behind on the retaining spring, which occurs when lines in the headlight housing are uncontrolled and / or when a relatiy rigid earth cable connected to a free end portion of the retaining spring is attached like a plug, the retaining spring can jump out of its latching. It is therefore not the case that the holding spring remains in its predetermined position in the event of lateral pressure, tensile load or pressure from behind. In addition, it is possible in the nature of the retaining spring that an incandescent lamp can be installed with its base tilted and can also be braced in this position with the retaining spring. This is due to the length of the spring, its bending shape and its relatively low rigidity.

Aufgabe der Erfindung ist es deshalb, eine nach dem Oberbegriff des Patentanspruchs 1 beschriebene Befestigung der Glühlampe in der Öffnung des Reflektors eines Scheinwerfers in der Weise auszubilden, daß es unmöglich ist, ein falsches Einsetzen der Glühlampe durch Verkanten bzw. Verdrehen vorzunehmen. Dabei soll es auch unerheblich für den Festsitz der Haltefeder sein, ob auf die Haltefeder axial von hinten oder seitlich Druck ausgeübt wird. Außerdem soll gleichzeitig das Lösen bzw. Einrasten der Haltefeder in einer bedienungsfreundlichen, unkomplizierten Art und Weise möglich sein.The object of the invention is therefore a fastening described in the preamble of claim 1 the bulb in the opening of the reflector of a headlamp in such a way that it is impossible to incorrectly insert the bulb by tilting or twisting. It should also be irrelevant for the tight fit of the retaining spring, whether pressure is exerted axially on the retaining spring from behind or laterally. In addition, the release or engagement of the retaining spring should be possible in a user-friendly, uncomplicated manner.

Gemäß der Erfindung wird diese Aufgabenstellung dadurch gelöst, daß aus den beiden Schenkeln des U-förmigen Mittelteils der Haltefeder jeweils eine Zunge frei geschnitten ist, die mit ihren freien Enden unter Vorspannung auf dem tellerförmigen Sockel der Glühlampe aufliegen, wobei zwischen den bogenförmigen Übergängen vom U-förmigen Mittelteil zu den freien Schenkeln und dem tellerförmigen Sockel der Glühlampe im eingebauten Zustand ein kleiner Spalt verbleibt. Erhöht sich beispielsweise der axiale Druck von hinten auf die Haltefeder, so kann die Haltefeder in dem Maße nachgeben, bis der Spalt sich auf Null reduziert hat und mit dem Anliegen der bogenförmigen Übergänge auf dem Sockel der Glühlampe eine ungleich stärkere Gegenkraft aufgrund der großen Starrheit der Haltefeder wirksam wird. Gleichzeitig verhindert dieser Zustand ein Überbiegen der freigeschnittenen Zungen. Auch bei Anliegen der bogenförmigen Übergänge an dem tellerförmigen Sockel bleibt die Haltefeder aufgrund der Vorspannnung im Einhängebereich verrastet. Die große Starrheit der Haltefeder verhindert auch, daß bei evtl. verkantet eingelegtem Lampensockel, die Haltefeder geschlossen bzw. verrastet werden kann, da hierfür die Elastizität über die Länge der Feder nicht ausreicht.According to the invention, this object is achieved in that a tongue is cut freely from the two legs of the U-shaped central part of the retaining spring, which rest with their free ends under tension on the plate-shaped base of the incandescent lamp, wherein between the arcuate transitions from the U -shaped middle part to the free legs and the plate-shaped base of the incandescent lamp remains a small gap in the installed state. If, for example, the axial pressure from behind increases on the retaining spring, the retaining spring can yield to the extent that the gap has reduced to zero and that the arched transitions on the base of the incandescent lamp create an incomparably stronger counterforce due to the great rigidity of the Retaining spring is effective. At the same time, this condition prevents the cut tongues from bending over. Even when the arcuate transitions are in contact with the plate-shaped base, the retaining spring remains locked in the hooking area due to the pretension. The great rigidity of the retaining spring also prevents the retaining spring from being able to be closed or locked when the lamp base is possibly tilted, since the elasticity over the length of the spring is insufficient for this.

Ein weiterer Vorteil ist, daß die die exakte Einbaulage bestimmenden Arretierungselemente zungenförmig ausgebildet sind, wobei ihre freien Enden als Schwenk- und Arretierungselemente für die Haltefeder dienen und das Arretierungselement einen hakenförmigen Freischnitt im seitlichen Öffnungsrand aufweist und das Schwenkelement T-förmig ausgeführt ist. Diese Arretierungselemente bestimmen durch ihre Länge in Verbindung mit den Abmaßen der freigeschnittenen Zungen die Vorspannung, die auf den tellerförmigen Sockel der Glühlampe wirkt, zum anderen ermöglichen sie die unkomplizierte schnelle Handhabung der Feder beim Verschließen oder Öffnen, tragen aber auch dazu bei, daß es nicht möglich ist, einen verkanteten Lampensockel festzuspannen, auch ist eine Fertigung dieser Elemente als gestanzte Formteile sehr wirtschaftlich auszuführen.Another advantage is that the locking elements determining the exact installation position are tongue-shaped, their free ends serving as pivoting and locking elements for the retaining spring and the locking element having a hook-shaped cutout in the lateral opening edge and the pivoting element being T-shaped. These locking elements determine by their length in conjunction with the dimensions of the cut tongues the bias that acts on the plate-shaped base of the incandescent lamp, on the other hand, they allow the uncomplicated quick handling of the spring when closing or opening, but also help that it does not it is possible to clamp a tilted lamp base, and it is also very economical to manufacture these elements as stamped molded parts.

Ebenfalls ist es von Vorteil, daß der eine freie Schenkel der Haltefeder U-förmig freigeschnitten und eingerollt ist und die freien Schenkel der U-Form so weit eingerollt sind, daß ein Spalt verbleibt, der geringfügig enger ist, als die Stärke des T-förmigen Freischnitts. Dies ermöglicht die einfache Fertigung eines Scharniers, das für die Bedienungsfreundlichkeit der Haltefeder maßgeblich ist, in dem man sie einfach aufklappt. Eingehängt wird die Feder zuvor über den leicht aufgebogenen Spalt, in dem T-förmigen Freischnitt, worin sie dann ohne weiteres Zutun verhakt und schwenkbar bleibt.It is also advantageous that the one free leg of the retaining spring is cut out and rolled in a U-shape and the free legs of the U-shape are rolled in so far that a gap remains that is slightly narrower than the thickness of the T-shaped Free cut. This enables the simple manufacture of a hinge, which is decisive for the user-friendliness of the retaining spring, by simply opening it. The spring is first hooked over the slightly bent gap, in the T-shaped free cut, in which it then hooks and remains pivotable without further action.

In einer weiteren zweckmäßigen Ausführungsform der Erfindung weist der andere freie Schenkel der Haltefeder eine Öffnung für die Verrastung mit dem hakenförmigen Freischnitt im Öffnungsrand des Reflektors auf, wobei der mit dem Arretierungselement zusammenwirkende Rand der Verrastungsöffnung entgegen der Schließrichtung der Haltefeder hochgestellt ist. Damit ist gewährleistet, daß ein alleiniges Herunterdrücken des freien Schenkels der Haltefeder nicht genügt, um die Verrastung zu lösen. Für diesen Fall wäre noch zusätzlich eine seitliche Druckkomponente nötig.In a further expedient embodiment of the invention, the other free leg of the retaining spring has an opening for latching with the hook-shaped cut-out in the opening edge of the reflector, the edge of the latching opening cooperating with the locking element being raised opposite to the closing direction of the retaining spring. This ensures that simply pressing down the free leg of the retaining spring is not sufficient to release the catch. For in this case an additional side pressure component would be necessary.

Ein weiterer wesentlicher Vorteil der Erfindung ist, daß der die beiden Schenkel des mittleren U-förmigen Teils verbindende Steg ebenflächig ausgebildet und eine parallel zur Schwenkachse verlaufende, als Flachstecker ausgebildete Verlängerung aufweist. Dies erlaubt den Massestecker kostengünstig in die Gestaltung der Haltefeder einzubringen und gewährleistet bei eventueller Zug- bzw. Druckbelastung, daß sich die Haltefeder aus der Verrastung nicht ungewollt lösen kann.Another important advantage of the invention is that the web connecting the two legs of the central U-shaped part is of flat design and has an extension which is parallel to the swivel axis and is designed as a flat plug. This allows the ground plug to be inserted cost-effectively into the design of the retaining spring and, in the event of tensile or compressive loads, ensures that the retaining spring cannot unintentionally release from the catch.

Der Scheinwerfer besteht im wesentlichen aus dem Reflektor (1) und der mit ihm verklebten, aber nicht dargestellten Lichtscheibe, einer Öffnung (2) im Scheitel des Reflektors (1), in die die Glühlampe (9) eingesetzt wird. Ein tellerförmiger Sockel (4) der Glühlampe (9) liegt am Öffnungsrand (3) des Reflektors (1) an und wird von der W-förmigen Haltefeder (5) umspannt. Zwei freie Schenkel (6, 7) der Haltefeder (5), wobei der eine Schenkel scharnierartig (6) und der andere Schenkel eine Rastverbindung (7) mit dem Reflektor (1) eingeht, sind mit dem Öffnungsrand (3) verbunden. Der mittlere Bereich (8) der W-förmigen Haltefeder (5) überspannt berührungslos den Mittenkontakt (21) der Glühlampe (9).The headlight consists essentially of the reflector (1) and the lens, but not shown, glued to it, an opening (2) in the apex of the reflector (1), into which the light bulb (9) is inserted. A plate-shaped base (4) of the light bulb (9) lies against the opening edge (3) of the reflector (1) and is spanned by the W-shaped retaining spring (5). Two free legs (6, 7) of the retaining spring (5), one leg being hinge-like (6) and the other leg forming a snap-in connection (7) with the reflector (1), are also included connected to the opening edge (3). The central area (8) of the W-shaped retaining spring (5) spans the center contact (21) of the incandescent lamp (9) without contact.

Aus zwei Schenkeln eines U-förmigen Mittelteils (8) der Haltefeder (5) sind jeweils eine Zunge (10) freigeschnitten, die mit ihren freien Enden (11) unter Vorspannung auf dem tellerförmigen Sockel (4) der Glühlampe (9) aufliegen. Dabei verbleibt zwischen zwei bogenförmigen Übergängen (12) vom U-förmigen Mittelteil (8) zu den freien Schenkeln (6, 7) und dem tellerförmigen Sockel (4) der Glühlampe (9) ein kleiner Spalt (13).A tongue (10) is cut free from two legs of a U-shaped central part (8) of the retaining spring (5), the tongues (10) of which rest with their free ends (11) under prestress on the plate-shaped base (4) of the light bulb (9). A small gap (13) remains between two arcuate transitions (12) from the U-shaped central part (8) to the free legs (6, 7) and the plate-shaped base (4) of the incandescent lamp (9).

Zwei, die exakte Einbaulage bestimmenden Arretierungselemente sind zungenförmig ausgebildet, und dienen den freien Schenkeln (6, 7) der Haltefeder (5) zur Befestigung, wobei ein hakenförmiger Freischnitt (14) des Reflektors (1) und ein T-förmiges Schwenkelement (15) im seitlichen Öffnungsrand (3) angeordnet sind. In dem T-förmigen Schwenkelement (15) ist der freie Schenkel (6) der Haltefeder (5) eingehängt. Dafür ist der freie Schenkel (6) U-förmig frei geschnitten und von den Enden soweit eingerollt, daß ein Spalt (16) verbleibt, der geringfügig enger als die Stärke des Schwenkelements (15) ist. Dies verhindert, daß die Haltefeder (5) sich ungewollt im entrasteten Zustand aushängen kann.Two locking elements, which determine the exact installation position, are tongue-shaped and serve the free legs (6, 7) of the retaining spring (5) for fastening, a hook-shaped free cut (14) of the reflector (1) and a T-shaped pivot element (15) are arranged in the lateral opening edge (3). The free leg (6) of the retaining spring (5) is suspended in the T-shaped pivot element (15). For this purpose, the free leg (6) is cut freely in a U-shape and rolled up from the ends to such an extent that a gap (16) remains which is slightly narrower than the thickness of the pivot element (15). This prevents the retaining spring (5) from unintentionally detaching in the unlocked state.

Im hakenförmigen Freischnitt (14) ist der freie Schenkel (7) der Haltefeder (5) befestigt, in dem er eine Verrastöffnung (17) für den hakenförmigen Freischnitt (14) aufweist, wobei der mit dem Arretierungselement zusammenwirkende Rand (18) der Verrastungsöffnung (17) entgegen der Schließrichtung der Haltefeder (5) hochgestellt ist.The free leg (7) of the retaining spring (5) is fastened in the hook-shaped free cut (14), in which it has a latching opening (17) for the hook-shaped free cut (14), the edge (18) of the latching opening (18) cooperating with the locking element ( 17) is raised against the closing direction of the retaining spring (5).
