Description

Die Erfindung betrifft eine Leuchte, in deren eine Handhabe bildendem Gehäuse aus Kunststoff eine mit Umfangs- und Mittelflächenpol ausgestattete Knopfzellenbatterie entgegen der Kraft eines an ihr anliegenden, elastischen Elementes in die Schaltkontaktstellung bringbar ist, indem ein Teilbereich des Mittelflächenpols der Knopfzellenbatterie in Berührung tritt zu einem Abschnitt einer Kontaktlamelle, wobei die Knopfzellenbatterie in einer Aufnahmekammer des Gehäuses einliegt und oder Umfangspol der Knopfzellenbatterie in ständiger Berührungsanlage (Dauerkontakt) steht zu einer sich tangential zur Knopfzellenbatterie erstreckenden Kontaktfeder, deren Breite mindestens dem Hub der Knopfzellenbatterie entspricht.The invention relates to a luminaire in whose a plastic housing handle a button cell battery equipped with a circumferential and central surface pole can be brought into the switch contact position against the force of an elastic element lying against it, by a partial area of the central surface pole of the button cell battery coming into contact with one Section of a contact lamella, the button cell battery lying in a receiving chamber of the housing and or the peripheral pole of the button cell battery in constant contact (permanent contact) to a contact spring extending tangentially to the button cell battery, the width of which corresponds at least to the stroke of the button cell battery.

Eine derartige Leuchte ist aus der DE-U-1 850 084 bekannt, die eine streifenförmige Kontaktlamelle mit zentral hochgebogenem, freigeschnittenen Schaltfingerkontakt aufweist. Ferner ist eine Gummiringfeder vorgesehen, die einseitig auf der Kontaktlamelle aufliegt und anderseitig mit dem Mittelflächenpol einer Knopfzellenbatterie in Berührung steht. Die Funktionsicherheit dieser Leuchte ist nicht immer gewährleistet, da zur Kontaktgabe die Knopfzellenbatterie derart zu beaufschlagen ist, daß die Gummiringfeder möglichst gleichmäßig zusammengequetscht wird. Dieses bedarf einer kraftaufwendigen, ganz gezielten, zentralen Druckbetätigung, da nur das Zentrum des Mittelflächenpols mit dem zentral hochgebogenen Schaltfingerkontakt der Kontaktlamelle in Berührung treten kann. Randseitige Druckbeaufschlagung der Knopfzellenbatterie führt hingegen zumeist nicht zur Kontaktgabe, da der randnahe Bereich des Mittelflächenpoles von der Gummiringfeder abgedeckt ist. Ferner weist diese bekannte Leuchte auf Grund der Gummiringfeder eine relativ große Dicke auf.Such a luminaire is known from DE-U-1 850 084, which has a strip-shaped contact lamella with a centrally raised, cut-out switching finger contact. Furthermore, a rubber ring spring is provided which rests on one side on the contact lamella and on the other side is in contact with the central surface pole of a button cell battery. The functional safety of this lamp is not always guaranteed, since the button cell battery must be applied in such a way that the rubber ring spring is squeezed together as evenly as possible. This requires a forceful, very targeted, central pressure actuation, since only the center of the center surface pole can come into contact with the centrally bent switching finger contact of the contact plate. Pressurization of the button cell battery on the edge, on the other hand, usually does not lead to contact since the area near the edge of the central surface pole is covered by the rubber ring spring. Furthermore, this known lamp has a relatively large thickness due to the rubber ring spring.

Aus der DE-A-3 126 774 geht eine mit einem Schlüssel verbindbare Leuchte hervor, die eine Kegelspiralfeder aufweist, welche ein ständiges Leitelement zwischen dem Mittelflächenpol einer Knopfzellenbatterie und einer Kontaktscheibe bildet. Ferner ist ein Kontaktring vorgesehen, der mit dem Mittelflächenpol der Knopfzellenbatterie zusammenwirkt. Der Kontaktring wird nur an zwei einander diametral gegenüberliegenden Punkten gehalten und erstreckt sich ansonsten frei im Inneren des Gehäuses der Lampe. Auf Grund der größtenteils fehlenden Abstützung kann sich der Ring durch zu kräftige Kontaktbeaufschlagung mittels der Knopfzellenbatterie verformen, so daß die Funktionsicherheit der Leuchte in Frage gestellt ist. Ferner ist die Lage der Kegelspiralfeder nicht hinreichend gesichert, so daß diese verrutschen und damit die Funktionssicherheit in Frage stellen kann. Ferner besteht Kurzschlußgefahr, wenn beim Niederdrücken der Knopfzellenbatterie diese relativ stark verkantet wird, so daß der Kontaktring gegen die Windungen der Kegelspiralfeder gedrückt wird. Die Kurzschlußgefahr soll zwar durch einen Puffer verhindert werden, der jedoch einen derartig kleinen Durchmesser besitzt, daß er ein starkes Verkanten der Knopfzelle ohne weiteres zuläßt. Eine Vergrößerung des Durchmessers des Puffers ist nicht möglich, weil dann kein Raum mehr für die Kegelspiralfeder zur Verfügung steht bzw. diese zu nahe an den Kontaktring herantritt.DE-A-3 126 774 shows a lamp which can be connected with a key and which has a conical spiral spring which forms a permanent guide element between the central surface pole of a button cell battery and a contact disk. Furthermore, a contact ring is provided which interacts with the central surface pole of the button cell battery. The contact ring is held only at two diametrically opposite points and otherwise extends freely inside the housing of the lamp. Due to the largely lack of support, the ring can deform due to excessive contact with the button cell battery, so that the functional safety of the lamp is questioned. Furthermore, the position of the conical spiral spring is not adequately secured, so that it slips and can thus jeopardize the functional reliability. Furthermore, there is a risk of short circuit if the button cell battery is tilted relatively strongly so that the contact ring is pressed against the windings of the conical spiral spring. The risk of short-circuiting is to be prevented by a buffer which, however, has such a small diameter that it readily permits the button cell to tilt strongly. It is not possible to increase the diameter of the buffer because then there is no more space available for the conical spiral spring or it comes too close to the contact ring.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, eine gattungsgemäße Leuchte zu schaffen, die extrem flach und betriebssicher ist.In contrast, the invention has for its object to provide a generic lamp that is extremely flat and reliable.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Kontaktlamelle einen kreisförmigen, auf dem Gehäuseboden aufliegenden Ringabschnitt aufweist und daß das elastische Element als konzentrisch zum Ringabschnitt verlaufende Druckfeder ausgebildet ist, von der mindestens die bodenseitige Endwindung in einer Vertiefung des Gehäusebodens einliegt, wobei der Durchmesser der Vertiefung kleiner ist als eine die Vertiefung umgebende Ringabschnittsöffnung des Ringabschnitts, auf den in Schaltkontaktstellung der Mittelflächenpol der Knopfzellenbatterie aufsetzt.This object is achieved in that the contact lamella has a circular ring section resting on the housing base and that the elastic element is designed as a compression spring running concentrically to the ring section, of which at least the bottom end turn lies in a recess in the housing base, the diameter of the The depression is smaller than a ring section opening of the ring section surrounding the depression, onto which the central surface pole of the button cell battery is placed in the switching contact position.

Die Unteransprüche sind vorteilhafte Weiterbildungen des Erfindungsgegenstandes.The subclaims are advantageous developments of the subject matter of the invention.

Zufolge solcher Ausgestaltung ist eine zufolge extrem flacher Bauform günstigst einem Schlüssel zuordbare Leuchte hoher Funktionssicherheit und einfachen Aufbaus geschaffen. Selbst unter Berücksichtigung der bei Betätigung nicht auszuschließenden Kipplage der Knopfzellenbatterie setzt der gegenüber dem Mantel der Knopfzellenbatterie leicht vorstehende, ebenflächige Mittelflächenpol mit stets sicherem Schaltkontakt auf dem darunterliegenden, vom Gehäuseboden abgestützten kreisförmigen Ringabschnitt auf. Da durch die in viele Richtungen mögliche Kipplage immer wechselnde, randnahe Stellen zusammenarbeiten, besteht nicht so leicht die Gefahr einer Zunderbildung. Es ergibt sich vielmehr eine selbstreinigende Wirkung an den Kontaktstellen. Dieser randnahe Kontakt ist bei der gattungsbildenden Leuchte durch einen in diesem Bereich liegenden, die Druckfeder bildenden Gummiring abgedeckt. Auch läßt sich nun der Hubweg wesentlich verringern und dementsprechend auch die Bauhöhe. Bezüglich der Druckfeder besteht eine vorteilhafte Zuordnung dahingehend, daß ihre bodenseitige Endwindung in einer Vertiefung des Gehäusebodens liegt, deren Durchmesser kleiner ist als derjenige der Ringabschnitts-Öffnung. Die zentrale Lage der Druckfeder ist so sicher gewährleistet; es kann keine Querverlagerung stattfinden. Schließlich trägt die Einlagerung der Endwindung der Druckfeder im Falle des Einsatzes einer Kegelfeder zusätzlich zur Erzielung einer möglichst flachen Bauform bei. Die bauliche Zuordnung der Kontaktfeder ist ebenfalls montageeinfach und betriebssicher: Sie liegt in einem Schacht des Gehäuses ein derart, daß sie mit ihrem einen Ende den Aufnahmeraum für die Glühlampe umfangsseitig schneidet. Von Vorteil ist es dabei, daß die Kontaktfeder spitzwinklig zum parallel zum Schlüsselschaft ausgerichteten Aufnahmeraum verläuft. Um auch einen stets sicheren Kontaktschluß zur Glühlampe sicherzustellen, dies sogar unabhängig von gewissen Toleranzabweichungen der EingerichtteiIe, wird weiterhin vorgeschlagen, daß die Kontaktlamelle mit einer jenseits der Kontaktfeder aus der Ebene des Ringabschnitts abgewinkelten Kontaktfahne am Glühlampensockel anliegt und die so gebildete Kontaktfahne zusätzlich durch einen elastischen, gehäuseseitig abgestützten Körper anlagebelastet ist. Diesbezüglich erweist es sich als vorteilhaft, daß der elastische Körper zylindrisch gestaltet ist, in einem Schacht steckt und von einem Niederhalter des Gehäusedeckels überlagert ist. Die entsprechend federnde Anlage läßt sich aber auch für die Kontaktfeder nutzen, indem die in ständiger Berührungsanlage am Umfangsflächenpol stehende Kontaktfeder mit ihrem freien Ende federnd am Glühlampensockel anliegt und dort durch einen elastischen oder federfähigen Körper zusätzlich anlagebelastet ist (Fig. 20). Zur optimalen Fixierung des Ringabschnitts erweist es sich schließlich als vorteilhaft, daß der Ringabschnitt der Kontaktlamelle randseitig mehrere, im wesentlichen in gleicher Winkelverteilung angeordnete Krallen aufweist, die sich in der zylindrischen Wandung der Aufnahmekammer für die Knopfzellenbatterie widerhakenartig verkrallen. Diesbezüglich ist es zusätzlich günstig, daß die Verkrallung in in Einsteckrichtung verlaufenden Führungsschächten erfolgt.As a result of such an embodiment, a luminaire which is extremely flat and can be assigned to a key with a high level of functional reliability and simple construction is created in a most favorable manner. Even taking into account the tilting position of the button cell battery that cannot be ruled out when it is actuated, the flat center surface pole, which protrudes slightly from the jacket of the button cell battery and always has a safe switching contact, is placed on the circular ring section underneath which is supported by the housing base. Since the tilting position, which is possible in many directions, means that changing places close to the edge always work together, there is not so easily a risk of scale formation. Rather, there is a self-cleaning effect at the contact points. This contact close to the edge is covered in the generic luminaire by a rubber ring in this area that forms the compression spring. Also, the stroke can now be significantly reduced and accordingly the overall height. With regard to the compression spring, there is an advantageous assignment in that its bottom end turn lies in a depression in the housing base, the diameter of which is smaller than that of the ring section opening. The central position of the compression spring is thus guaranteed; no cross-shift can take place. Finally, the inclusion of the end turn of the compression spring in the case of Use of a conical spring in addition to achieve the most flat possible design. The structural assignment of the contact spring is also easy to install and reliable: it is located in a shaft of the housing in such a way that it cuts the receiving space for the incandescent lamp on the circumference with one end. It is advantageous that the contact spring extends at an acute angle to the receiving space aligned parallel to the key shaft. In order to ensure that the contact between the incandescent lamp is always secure, even regardless of certain tolerance deviations of the components, it is further proposed that the contact lamella contacts the incandescent lamp base with a contact tab angled beyond the contact spring out of the plane of the ring section and the contact tab formed in this way additionally by an elastic one , housing-supported body is system-loaded. In this regard, it proves to be advantageous that the elastic body is cylindrical, is in a shaft and is overlaid by a hold-down of the housing cover. The correspondingly resilient system can also be used for the contact spring, in that the contact spring, which is in constant contact with the peripheral surface pole, rests with its free end resiliently on the bulb base and is additionally stressed there by an elastic or resilient body (Fig. 20). For optimal fixing of the ring section, it finally proves to be advantageous that the ring section of the contact lamella has a plurality of claws on the edge side, arranged essentially in the same angular distribution, which claw like barbs in the cylindrical wall of the receiving chamber for the button cell battery. In this regard, it is also favorable that the clawing takes place in guide shafts running in the direction of insertion.

Der Reidenbereich des Schlüssels 1 ist als Leuchte L gestaltet. Deren die Handhabe des Schlüssels bildendes Gehäuse 2 nimmt zentral eine Knopfzellenbatterie 3 auf.The area of the key 1 is designed as a lamp L. The housing 2 which forms the handle of the key accommodates a button cell battery 3 centrally.

Das flache, gemäß Fig. 1 scheibchenförmige Gehäuse ist aus Isolationsmaterial, z. B. Kunststoff, hergestellt und mittels eines ringförmigen Deckels 4 im Wege einer randseitigen Klipsverbindung verschließbar. Von der dem Deckel 4 zugewandten Breitfläche des Gehäuses 2 geht eine zentrale, zylindrische Aufnahmekammer 5 für die Knopfzellenbatterie 3 aus. Letztere ist darin axial entgegen Federbelastung verlagerbar. Die entsprechende Druckfeder 6 stützt sich auf dem Boden 7 der Aufnahmekammer 5 ab. Mindestens ihre bodenseitige Endwindung 6' steckt in einer die Vertiefung 8 des Bodens 7. Es handelt sich um eine Kegelfeder, deren andere Endwindung 6" die untere Flachseite der Knopfzellenbatterie 3 mittig in Richtung der Grundstellung (Fig. 5) belastet.The flat, disc-shaped housing shown in FIG. 1 is made of insulation material, for. B. plastic, manufactured and closed by means of an annular cover 4 by means of an edge-side clip connection. A central, cylindrical receiving chamber 5 for the button cell battery 3 extends from the wide surface of the housing 2 facing the cover 4. The latter is axially displaceable against spring loading. The corresponding compression spring 6 is supported on the bottom 7 of the receiving chamber 5. At least its bottom end turn 6 'is in one of the recess 8 of the bottom 7. It is a conical spring, the other end turn 6 "loads the lower flat side of the button cell battery 3 in the middle in the direction of the basic position (FIG. 5).

Auf dem Gehäuseboden 7 liegt ferner der Ringabschnitt 9' einer Kontaktlamelle 9. Es handelt sich um ein zumindest im Bereich des Ringabschnitts ebenflächig gestaltetes Stanzteil. Der Ringabschntt 9' beläßt einen so weiten Innenfreiraum, daß die in der Vertiefung 8 sitzende Druckfeder 6 nicht mit der leitfähigen Kontaktlamelle 9 in Berührung kommt. Der Durchmesser der Vertiefung 8 ist vielmehr deutlich kleiner als derjenige der Ringabschnitts- Öffnung 10.On the housing base 7 there is also the ring section 9 'of a contact lamella 9. It is a stamped part which is designed to be flat at least in the area of the ring section. The Ringabschntt 9 'leaves such a wide inner space that the compression spring 6 sitting in the recess 8 does not come into contact with the conductive contact plate 9. Rather, the diameter of the depression 8 is significantly smaller than that of the ring section opening 10.

In Kontaktstellung (Fig. 6) setzt der von der unteren Flachseite gebildete Mittelflächenpol MP der Knopfzellenbatterie 3 auf die ihm zugewandte Seite des Ringabschnitts 9' auf.In the contact position (FIG. 6), the central surface pole MP of the button cell battery 3 formed by the lower flat side is placed on the side of the ring section 9 'facing it.

Die federbelastete Grundstellung ist dagegen durch eine Ringschulter 11 einer die Knopfzellenbatterie 3 überfangenden, hütchenartigen Betätigungstaste 12 definiert. Letztere ragt mit ihrem querschnittskleineren, zylindrischen Abschnitt in eine formentsprechende, durchgehende Öffnung 13 des Deckels 4. Die Ringschulter 11 tritt gegen den unterseitigen Innenrand der Öffnung 13. Der Hutraum nimmt den oberen, zylindrischen Abschnitt der Knopfzellenbatterie auf, die sich im Bereich der unteren Hutrandkante bis auf das Umfangsmaß derselben verbreitert, um schließlich in Richtung des Bodens 7 flach kegelstumpfförmig auszulaufen. Die Absatzschulter zwischen zylindrischem und kegelstumpfförmigem Abschnitt der Knopfzellenbatterie ist mit 14 bezeichnet. Der periphere Übergang weist eine Querrundung 15 auf. Die Mantelwand dieses Abschnitts bildet den Umfangspol UP.The spring-loaded basic position, on the other hand, is defined by an annular shoulder 11 of a cone-like actuation button 12 overlapping the button cell battery 3. The latter protrudes with its smaller cross-section, cylindrical section in a shape-corresponding, continuous opening 13 of the lid 4. The annular shoulder 11 occurs against the underside inner edge of the opening 13. The hat space receives the upper, cylindrical section of the button cell battery, which widens in the area of the lower edge of the hat to the circumference of the same , in order to finally end in the shape of a truncated cone in the direction of the bottom 7. The shoulder between the cylindrical and frustoconical section of the button cell battery is designated by 14. The peripheral transition has a transverse rounding 15. The jacket wall of this section forms the peripheral pole UP.

Der Umfangspol UP steht in ständiger Berührungsanlage zu einer sich im wesentlichen tangential zur Knopfzellenbatterie 3 erstreckenden Kontaktfeder 16. Deren Breite entspricht mindestens dem Hub x der Knopfzellenbatterie 3. Gehalten ist die Kontaktfeder in einem Schacht 17 (Fig. 3 und 13) des Gehäuses 2. Der Schacht 17 endet in einem Abstand y (Fig. 6) vor der aufnahmekammersetigen Fläche 7' des Bodens 7, welcher Abstand großer ist als die Dicke der Kontaktlamelle 9. So kann es nicht zu einer Berührung zwischen dieser und der Kontaktfeder 16 kommen. In Richtung des Gehäuserandes schließt an die zylindrische Aufnahmekammer 5 ein Aufnahmeraum 18 für die Glühlampe 19 der Leuchte L an. Aufnahmeraum 18 und Aufnahmekammer 5 sind auf einem Teilabschnitt zueinander hin offen. Die Kontaktfeder 16 erstreckt sich in der entsprechenden Durchbrechungszone und ist nur an ihren beiden Schmalenden 16' und 16" gefesselt, so daß sie bei Abwärtsverlagerung der Knopfzellenbatterie dort ihren Feder-Ausweichraum findet; der Schacht 17 nimmt nämlich einen in Verlagerungsrichtung liegenden Schrägungsverlauf. Dies hat den Vorteil, daß mit zunehmender Eindrückbewegung ein noch festerer Reilbkontakt zwischen dem Umfangspol und der korrespondierenden Federfläche entsteht.The peripheral pole UP is in constant contact with a contact spring 16 which extends essentially tangentially to the button cell battery 3. The width thereof corresponds at least to the stroke x of the button cell battery 3. The contact spring is held in a shaft 17 (FIGS. 3 and 13) of the housing 2. The shaft 17 ends at a distance y (FIG. 6) in front of the receiving chamber set surface 7 'of the base 7, which distance is greater than the thickness of the contact lamella 9. Thus, there can be no contact between the latter and the contact spring 16. A receiving space 18 for the incandescent lamp 19 of the lamp L adjoins the cylindrical receiving chamber 5 in the direction of the edge of the housing. The receiving space 18 and the receiving chamber 5 are open to one another on a partial section. The contact spring 16 extends in the corresponding break-through zone and is only tied at its two narrow ends 16 'and 16 ", so that when the button cell battery is moved downward it finds its spring escape space there, namely the shaft 17 takes an inclined course in the direction of displacement. This has the advantage that with increasing push-in movement there is an even firmer contact between the peripheral pole and the corresponding spring surface.

Die Glühlampe 19 bildet vor dem Glaskolben einen Ringkragen 20 aus. Letzterer steckt in einem Querschacht 21 des Gehäuses 2. Die Glühlampe 19 ist in Richtung des Schlüsselschaftes ausgerichtet. Sie erstreckt sich in der Ebene der Schlüsselschmalkante. Die Kontaktfeder verläuft spitzwinklig (Winkel Alpha) zum parallel zum Schlüsselschaft 1' ausgerichteten Aufnahmeraum (Fig. 3 und 13).The incandescent lamp 19 forms an annular collar 20 in front of the glass bulb. The latter is located in a transverse shaft 21 of the housing 2. The light bulb 19 is oriented in the direction of the key shaft. It extends in the plane of the key edge. The contact spring extends at an acute angle (angle alpha) to the receiving space aligned parallel to the key shaft 1 '(FIGS. 3 and 13).

Die Kontaktlamelte 9 ragt mit einer jenseits der Kontaktfeder 16 aus ihrer Flachebene abgewinkelten Kontaktfahne 22 bis in den Bereich des Glühlampensockels 23. Die Fahne nimmt anfangs einen nahezu tangentialen Verlauf zum Ringabschnitt 9' und ist dann einmal oder zweimal quer zur Erstreckungsrichtung abgewinkelt.The contact lamella 9 projects with a contact lug 22 angled beyond its contact spring 16 out of its flat plane into the area of the bulb base 23. The lug initially takes an almost tangential course to the ring section 9 'and is then angled once or twice transversely to the direction of extension.

Die tangential gerichtete Kontaktfeder 16 tritt mit ihrem einen, d. h. glühlampenseitigen Ende, den Aufnahmeraum für die Glühlampe umfangsseitig anschneidet, gegen den gewindetragenden Mantel der Glühlampe 19, und zwar konkret gegen den durch Auswärtsfalten erzeugten Ringkragen 20, welcher sich rückwärtig noch in einen gewindefreien, zylindrischen Abschnitt fortsetzt, so daß der Kontakt über das Schmalende 16" stets sicher aufrechterhalten ist.The tangentially directed contact spring 16 occurs with one, d. H. The end on the incandescent lamp side, which cuts the receiving space for the incandescent lamp on the circumference, against the thread-bearing jacket of the incandescent lamp 19, specifically against the annular collar 20 produced by outward folding, which continues at the rear into a thread-free, cylindrical section, so that the contact via the narrow end 16 "is always safely maintained.

Die Betätigungstaste schließt randseitig ebenengleich mit der äußeren Breitfläche des Deckels 4 ab, ist zum Zentrum hin aber schwach konkav gehöhlt. Der Deckel 4 verschließt auch den nach oben hin offenen Aufnahmeraum 18 für die Glühlampe 19. Die Raumtiefe entspricht im wesentlichen der des Glühlampendurchmessers.The actuation button ends flush with the outer broad surface of the cover 4, but is concavely hollowed out towards the center. The cover 4 also closes the upwardly open receiving space 18 for the incandescent lamp 19. The depth of the space essentially corresponds to that of the incandescent lamp diameter.

Die Betätigung der Leuchte braucht nicht streng zentral zu erfolgen; aufgrund des Ringabschnitts 9' kommt bei gleich welcher Kipplage der Knopfzellenbatterie stets mindestens ein Teilbereich derselben in Berührung zum Ringabschnitt.The light does not need to be operated strictly centrally; due to the ring section 9 ', regardless of the tilting position of the button cell battery, at least a partial area thereof always comes into contact with the ring section.

Die mit einem Schlüsselschaft bestückbaren Leuchten gemäß dem zweiten und dritten Ausführungsbeispiel sind prinzipiell gleichen Aufbaues. Die Bezugsziffern sind,.soweit zum Verständnis erforderlich, sinngemäß übertragen, ohne daß bezüglich der übereinstimmenden Merkmale eine textliche Wiederholung erfolgt. Bezüglich des zweiten Ausführungsbeispieles (Fig. 9 bis 15) ergibt sich folgende Weiterbildung: Die am Glühlampensockel 23 federnd anliegende Kontaktfahne 22 der Kontaktlamelle 9 ist zur Verstärkung der federnden Anlage noch durch einen elastischen Körper 24, bspw. aus Schaumstoff, in Richtung der Glühlampe 19 belastet. Der in seiner Grundform zylindrische Körper ruht in einem hinter dem Lampensockel liegende Schacht 25 des Gehäuses 2. Der Schacht ist anteilig vom Aufnahmeraum 18 mitgebildet. Zum Einführen des stopfenartigen Körpers 24 wird dieser leicht komprimiert. Die Rückstellkraft führt zu der aus Fig. 13 ersichtlichen, etwas deformierten Form. Damit der elastische Körper 24 nicht aus dem Schacht heraustreten kann bzw. eine gegenüber der Schachthöhe verringerte Achsenlänge vorligen kann, geht vom Gehäusedeckel 4 ein deckungsgleich liegender Niederhalter 26 aus. Es handelt sich um einen angeformten zylindrischen Zapfen, der bis auf die Oberseite des elastischen Körpers reicht. Der Zapfen ist aus Fig. 15 erkennbar.The lights that can be equipped with a key shaft according to the second and third exemplary embodiments are basically of the same construction. As far as is necessary for understanding, the reference numbers are transferred analogously without a textual repetition of the matching features. With regard to the second exemplary embodiment (FIGS. 9 to 15), the following further development results: The contact lug 22 of the contact lamella 9, which rests resiliently on the bulb base 23, is in the direction of the bulb 19 to reinforce the resilient system by means of an elastic body 24, for example made of foam charged. The cylindrical body in its basic form rests in a shaft 25 of the housing 2 located behind the lamp base. The shaft is partly formed by the receiving space 18. To insert the plug-like body 24, it is slightly compressed. The restoring force leads to the somewhat deformed shape shown in FIG. 13. So that the elastic body 24 cannot emerge from the shaft or that there is an axis length that is reduced compared to the shaft height, a congruent hold-down device 26 extends from the housing cover 4. It is a molded cylindrical pin that extends to the top of the elastic body. The pin can be seen in FIG. 15.

Während in diesem Ausführungsbeispiel und in dem Ausführungsbeispiel gemäß den Fig. 1 bis 8 die Kontaktlamelle 9 zum Glühlampensockel 23 führt, ist beim Ausführungsbeispiel gemäß den Fig. 16 bis 21 die Kontaktlamelle 9 an den Ringkragen 20 der Glühlampe 19 geführt und die in ständiger Berührungsanlage zum Umfangsflächenpol UP stehende Kontaktfeder 16 an ihrem freien Ende mit dem Glühlampensockel 23 in Kontakt. Dies geht deutlich aus Fig. 20 hervor. Wie ersichtlich, nimmt die Kontaktfeder 16 einen mehrfach abgewinkelten Verlauf, wobei das unmittelbar in Kontakt stehende Ende V-förmig abgewinkelt ist und die V-Spitze am Glühlampensockel 23 anliegt. Außer der der Kontaktfeder innenwohnenden Anlagekraft ist dieses freie Ende ebenfalls durch einen elastischen oder federfähigen Körper 24' anlagebelastet. Dieser Körper besteht aus einer Platte, welche diagonal in den dortigen Schachtbereich eingesteckt ist und am freien V-Schenkel, diesen belastend, anliegt.While in this exemplary embodiment and in the exemplary embodiment according to FIGS. 1 to 8 the contact lamella 9 leads to the bulb socket 23, in the exemplary embodiment according to FIGS. 16 to 21 the contact lamella 9 is guided to the ring collar 20 of the bulb 19 and is in constant contact with the Circumferential surface pole UP standing contact spring 16 at its free end in contact with the bulb socket 23. This is clear from Fig. 20. As can be seen, the contact spring takes 16 a multiple angled course, the directly contacting end being angled in a V-shape and the V-tip resting on the bulb base 23. In addition to the contact force which is inherent in the contact spring, this free end is also loaded by an elastic or resilient body 24 '. This body consists of a plate, which is inserted diagonally into the shaft area there and lies against the free V-leg, which is stressful.

Im weiteren Unterschied zu den voraufgegangenen Lösungen ist die Maßnahme getroffen, daß sich die Kontaktlamelle 9 in der Richtung des Schlüsselschaftes erstreckt (Fig. 16). Ihre seitliche Abstützung wird von Rippen 27 gebildet, die sich seitlich der Kontaktlamelle 9 erstrecken. Auch die Grundform des Leuchtenkörpers weicht ab insofern, als dieser nun einen im wesentlichen dreieckigen Verlauf hat mit schwach konvex gewölbten Längsseiten. Die Klipszuordnung des Deckels ist auch anders gelöst, indem dieser einen Hammerkopf 28 ausbildet mit seitlichen, abgeschrägten Lappen, die entsprechende Hinterschneidungen des Gehäuses 2 hintergreifen. Das dem Hammerkopf 28 gegenüberliegende Ende des Deckels 4 hingegen ist einfach in der Aufnahmekammer 5 für die Knopfzellenbatterie 3 eingeklipst. Letztere weist entsprechende Rastvertiefungen 30 auf, in welche die Rastvorsprünge 31 des Deckels 4 einschnäppern.In contrast to the previous solutions, the measure is taken that the contact lamella 9 extends in the direction of the key shaft (FIG. 16). Your lateral support is formed by ribs 27 which extend laterally of the contact lamella 9. The basic shape of the lamp body also differs insofar as it now has an essentially triangular shape with slightly convex long sides. The clip assignment of the cover is also solved differently in that it forms a hammer head 28 with lateral, bevelled tabs which engage behind the corresponding undercuts of the housing 2. The end of the cover 4 opposite the hammer head 28, on the other hand, is simply clipped into the receiving chamber 5 for the button cell battery 3. The latter has corresponding locking recesses 30 into which the locking projections 31 of the cover 4 snap.

Eine Besonderheit des Ausführungsbeispieles gemäß den Fig. 9 bis 15 besteht noch darin, daß der Ringabschnitt 9' der Kontaktlamelle 9 randseitig mehrere, im wesentlichen in gleicher Winkelverteilung angeordnete Krallen 9" aufweist, die sich in der zylindrischen Wandung der Aufnahmekammer 5 für die Knopfzellenbatterie 3 verkrallen. Die Verkrallung erfolgt auf dem Grund von in Einsteckrichtung des Ringabschnittes 9' verlaufenden Führungsschächten 32, welche der Kontur der Krallen 9" entsprechend angepaßt sind und eine optimale Drehsicherung des kreisförmigen Ringabschnittes 9' sicherstellen.A special feature of the exemplary embodiment according to FIGS. 9 to 15 is that the ring section 9 ′ of the contact lamella 9 has a plurality of claws 9 ″ arranged essentially in the same angular distribution on the edge, which are located in the cylindrical wall of the receiving chamber 5 for the button cell battery 3 The clawing takes place on the bottom of guide shafts 32 which run in the direction of insertion of the ring section 9 'and which are adapted to the contour of the claws 9 "and ensure an optimal rotation lock of the circular ring section 9'.

Bei diesem gleichen Ausführungsbeispiel ist das einsteckseitige Ende des Schlüsselschaftes 1' gegabelt. Es tritt in einen der Gabelform entsprechenden Schacht des Gehäuses ein und wird durch einen in Richtung der Sperrgrundstellung federbelasteten Sperriegel 33 aufhebbar fixiert.In this same embodiment, the insertion end of the key shaft 1 'is forked. It enters a shaft of the housing corresponding to the fork shape and is fixed by a locking bolt 33 which is spring-loaded in the direction of the basic locking position.
