Abstract
Description
Die Erfindung betrifft einen Scheinwerfer für Fahrzeuge, mit einem Gehäuse, mit einer selbstrastend mit dem Gehäuse verbundenen lichtdurchlässigen Abschlußscheibe, mit mindestens einem Rastelement, welches mit einem der zu verbindenden Teile einstückig und quer zur Fügerichtung von Abschlußscheibe und Gehäuse federnd ausgeführt ist und mit mindestens einem Vorsprung, den das Rastelement selbsttätig hintergreift, wobei das Rastelement zum selbstrastenden Verbinden von Gehäuse und Abschlußscheibe einen ersten Gleitabschnitt aufweist.The invention relates to a headlight for vehicles, with a housing, with a self-locking connected to the housing translucent End disc, with at least one locking element, which with one of the connecting parts in one piece and transverse to the joining direction of the lens and Housing is designed resilient and with at least one projection, the Locking element automatically engages behind, wherein the locking element for self-locking Connecting housing and lens has a first sliding portion.
Ein solcher Scheinwerfer für Fahrzeuge ist aus der DE 28 46 990 A1 bekannt. Das die Abschlußscheibe tragende Gehäuse, welches von einem schalenförmigen Reflektor gebildet ist, weist am vorderen äußeren Rand ein Aufnahmebett für die Abschlußscheibe auf. In das Aufnahmebett ist ein Dichtungsmittel eingebracht. Als Dichtungsmittel kann eine in das Aufnahmebett eingesetzte Form- oder Strangdichtung, ein in das Aufnahmebett eingebrachter Klebstoff oder ein dauernd dickflüssiges Dichtungsmittel verwendet werden. Die Rastelemente sind an der Außenseite des Aufnahmebettes angeformt, über den gesamten Umfang des äußeren Randes des Gehäuses gleichmäßig verteilt und weisen in Lichtaustrittsrichtung. Die Abschlußscheibe weist an ihrem äußeren Randabschnitt angeformte Vorsprünge auf, welche radial zur optischen Achse nach außen gerichtet sind und in eine Öffnung der Rastelemente eingreifen. Bei einem Aufsetzen der Abschlußscheibe auf das Gehäuse gleiten ihre Vorsprünge an Gleitflächen der Rastelemente entlang. Dabei federn die Rastelemente soweit radial zur optischen Achse nach außen bis sie die Vorsprünge selbstrastend hintergreifen. Die Rastelemente stehen zwar nicht störend vom Scheinwerfer ab, jedoch kann sich die Abschlußscheibe ungewollt vom Gehäuse lösen, da die Vorsprünge der Abschlußscheibe wegen einem kleinen Federweg der Rastelemente nur mit einen sehr kleinen Endabschnitt in die Öffnungen der Rastelemente eingreifen können. Such a headlight for vehicles is known from DE 28 46 990 A1. The the closure disk bearing housing, which of a cup-shaped Reflector is formed, has at the front outer edge of a recording bed for the Disc on. In the receiving bed a sealant is introduced. When Sealant may be a molded or inserted into the receiving bed Strangdichtung, an introduced into the receiving bed adhesive or permanently thick sealant can be used. The locking elements are on the Formed outside of the bed, over the entire circumference of the outer edge of the housing evenly distributed and point in Light exit direction. The lens has at its outer edge portion molded projections, which directed radially to the optical axis to the outside are and engage in an opening of the locking elements. When putting on the Shield on the housing slide their projections on sliding surfaces of Along locking elements. In this case, the locking elements spring so far radially to the optical Axle outwards until they engage behind the projections self-locking. The Although locking elements are not disturbing from the headlight, but can the Unintentionally detach the closure plate from the housing, since the projections of the Shield because of a small travel of the locking elements only with one very small end portion can engage in the openings of the locking elements.
Aus dem deutschen Gebrauchsmuster 76 05 088 ist ein Scheinwerfer für Fahrzeuge bekanntgeworden, bei welchem die Rastelemente an den äußeren Rand der Abschlußscheibe angeformt sind und in Aufsetzrichtung der Abschlußscheibe weisen. Die Federrichtung der Rastelemente verläuft quer zu einer Radialen der optischen Achse. Die Rastelemente hintergreifen mit einem seitlich abstehenden Endabschnitt selbstrastend einen Vorsprung des Gehäuses. Beim Aufsetzen der Abschlußscheibe auf das Gehäuse gleiten die Vorsprünge des Gehäuses an Auflaufschrägen der Rastelemente entlang, bis die Rastelemente die Vorsprünge selbstrastend hintergreifen. Hierbei ist der Federweg der Rastelemente wegen ihrer kurzen Länge und wegen ihren in Federrichtung verlaufenden breiten Seitenflächen sehr klein. Deshalb kann ein sicherer Festsitz der Abschlußscheibe an dem Gehäuse nicht gewährleistet sein.From the German utility model 76 05 088 is a headlight for vehicles become known, in which the locking elements to the outer edge of the Cover disc are formed and in Aufsetzrichtung the lens point. The spring direction of the locking elements extends transversely to a radial of the optical axis. The locking elements engage behind with a laterally projecting End section self-locking a projection of the housing. When placing the Cover disc on the housing to slide the projections of the housing Run-up slopes of the locking elements along until the locking elements, the projections self-locking behind. Here is the spring travel of the locking elements because of their short length and because of their running in the spring direction wide side surfaces tiny. Therefore, a secure tight fit of the lens to the housing not be guaranteed.
Aufgabe der Erfindung ist es, den im Oberbegriff des Anspruchs 1 beschriebenen
Scheinwerfer für Fahrzeuge derart zu gestalten, daß das Rastelement auch dann
vom Scheinwerfer so wenig wie möglich nach außen absteht, wenn das Gehäuse
durch lange Gleitflächen a) leicht und schnell fügbar ist, b) der Federweg des
Rastelementes möglichst klein ist, um einen Werkstoff mit geringer Elastizität
verwenden zu können und c) Abschlußscheibe und Gehäuse durch einen großen
Eingriff zwischen Rastelement und Vorsprung sicher verbindbar ist. Diese Aufgabe
wird nach der Erfindung dadurch gelöst, daß der Vorsprung einen zweiten
Gleitabschnitt aufweist, welcher in Fügerichtung gesehen in jedem Punkt in einem
spitzen Winkel zur Federrichtung des Rastelementes verläuft und das der erste
Gleitabschnitt des Rastelementes in Federrichtung gesehen, in jedem Punkt in einem
spitzen Winkel zur Fügerichtung verläuft. Hierbei ist es zweckmäßig, wenn der spitze
Winkel zur Federrichtung vom Scheinwerfer weg und der spitze Winkel zur
Fügerichtung zum Vorsprung hin geöffnet ist. Als Vorsprung kann ein von dem
Gehäuse oder der Abschlußscheibe nach außen gerichteter Randabschnitt dienen,
welcher umlaufend ausgeführt oder im Bereich der Rastelemente unterbrochen
ausgeführt sein kann. Das Rastelement und der Vorsprung stehen nur sehr wenig
und somit nicht störend vom Scheinwerfer ab, wenn das Rastelement in seiner
Federrichtung gesehen, den Vorsprung mit mindestens einem seitlich abstehenden
Endabschnitt selbstrastend hintergreift und eine Lasche ist, welche mit ihren breiten
Seitenflächen in Federrichtung weisen und an ihrem freien Ende einen ersten
Gleitabschnitt aufweisen. Je dünnwandiger die Lasche ist, um so größer ist der
mögliche Federweg des Rastelements. Außerdem muß der den Vorsprung
hintergreifende Endabschnitt nicht dicker als die übrigen Bereiche der Lasche
ausgeführt sein.The object of the invention is described in the preamble of
Ein besonders großer Eingriff zwischen dem Rastelement und dem Vorsprung besteht, wenn in Fügerichtung gesehen der erste Gleitabschnitt des Rastelementes in einem zum Scheinwerfer hin geöffneten spitzen Winkel zur Federrichtung verläuft. Hierbei muß der Vorsprung radial zur optischen Achse entsprechend lang ausgeführt sein.A particularly large engagement between the locking element and the projection exists when viewed in the joining direction of the first sliding portion of the locking element extends in an opened to the headlight acute angle to the spring direction. In this case, the projection must be made correspondingly long radially to the optical axis be.
Das Rastelement und der Vorsprung können beim Fügen von Abschlußscheibe und Gehäuse annähernd mit einer gleichgroßen Kraft an jeder Stelle ihrer Gleitabschnitte aneinanderliegen, wenn der zweite Gleitabschnitt des Vorsprunges in Fügerichtung gesehen und der erste Gleitabschnitt des Rastelements in Federrichtung gesehen, konvex verläuft.The locking element and the projection can when joining the lens and Housing approximately with an equal force at each point of their sliding sections abut each other when the second sliding portion of the projection in the joining direction seen and the first sliding portion of the locking element seen in the spring direction, convex.
Das Fügen von Abschlußscheibe und Gehäuse ist mit einer sehr kleinen Kraft möglich, wenn der seitlich vom Rastelement abstehende Endabschnitt um einen annähernd in Fügerichtung verlaufenden Soll-Biege-Abschnitt des Rastelements schwenkbar ist. Beim Fügen von Abschlußscheibe und Gehäuse schwenkt der Endabschnitt um den Soll-Biege-Abschnitt nach außen und federt in der Soll-Lage in seine ursprüngliche Lage zurück, in welcher der Endabschnitt den Vorsprung selbstrastend hintergreift.The joining of lens and housing is with a very small force possible if the laterally projecting from the locking element end portion to a approximately in the joining direction extending desired bending section of the locking element is pivotable. When joining the lens and the housing pivots End portion around the target bending portion to the outside and springs in the desired position in its original position back, in which the end portion of the projection self-locking engages behind.
Zwischen der Abschlußscheibe und dem Gehäuse besteht eine sehr stabile und sichere Rastverbindung, wenn das Rastelement in Federrichtung gesehen T-förmig gestaltet ist, wobei die Endabschnitte des Querbalkens der T-Form jeweils einen Vorsprung mit einem zweiten Gleitabschnitt hintergreifen und der Längsbalken der T-Form zwischen beiden Vorsprüngen verläuft.Between the lens and the housing is a very stable and secure latching connection, when the locking element seen in the spring direction T-shaped is designed, wherein the end portions of the crossbar of the T-shape each one Projection with a second sliding portion engage behind and the longitudinal beam of the T-shape between the two projections extends.
Bei einem Scheinwerfer für Fahrzeuge, bei dem das Gehäuse am äußeren Rand ein Aufnahmebett für die Abschlußscheibe aufweist, ist es weiterhin vorteilhaft, wenn das Rastelement in einem Abstand zum Aufnahmebett an die Außenseite des Gehäuses angeformt ist und sich in einem Abstand über das Aufnahmebett hinweg erstreckt, wobei der Vorsprung an den äußeren Randabschnitt der Abschlußscheibe angeformt ist und in seiner Längsausdehnung quer zur Fügerichtung verläuft. Hierbei kann die Abschlußscheibe aus einem starren Material, wie zum Beispiel Glas hergestellt sein. Außerdem kann das Rastelement in Fügerichtung sehr lang ausgeführt sein und somit kann auch der Federweg des Rastelements am Endabschnitt bei einem Werkstoff mit geringer elastischer Eigenschaft ausreichend sein.In a headlamp for vehicles, wherein the housing at the outer edge of a Receiving bed for the lens, it is also advantageous if the Detent element at a distance from the receiving bed to the outside of the housing is formed and extends at a distance over the receiving bed away, wherein the projection integrally formed on the outer edge portion of the closure disc is and extends in its longitudinal extent transverse to the joining direction. Here, the Boss be made of a rigid material, such as glass. In addition, the locking element in the joining direction can be made very long and Thus, the spring travel of the locking element at the end portion at a Be sufficient material with low elastic property.
