Abstract

A key holder comprising a plate provided with an elastic ring and a detent pawl is insertable into a flat sleeve. The plate has a notch which receives an end section of the ring. The end section is non-displaceable in its fully inserted position since the notch lies within the opening shaft of the flat sleeve.

Description

Die Erfindung betrifft einen Schlüsselanhänger gemäß Gattungsbegriff des Hauptanspruches. Die bekannten Lösungen dieser Art (US-A-26 31 449) sind wegen ihrer Vielteiligkeit nicht nur herstellungs- und montagetechnisch nachteilig, sondern auch für die Handhabung sehr ungünstig. Das beigbare Element besteht dort aus einer Schnur oder dergleichen, deren freies Ende mit einem aufgeklemmten Ring bestückt ist. Dieser Ring liegt in der Nische. Das Aufbringen neuer Schlüssel oder das Entnehmen eines Schlüssels vom biegbaren Element verlangt eine hohe Fingerfertigkeit. Man muß den aufgeklemmten Endring des biegbaren Elementes vor allem sauber in der Nische halten bis man den Schieber wieder weit genug in die Hülse eingeschoben hat. Diese Handhabung würde sich noch erschweren, wenn der Schieber nicht an beiden Stirnenden solche biegbaren Elemente tragen würde, so daß man ihn also nicht mit dem gegenüberliegend vorstehenden biegbaren Element wieder in die Hülse bis in seine Raststellung hineinzeihen kann.The invention relates to a key fob according to the preamble of the main claim. The known solutions of this type (US-A-26 31 449) are not only disadvantageous because of their multiplicity in terms of production and assembly technology, but also very unfavorable for handling. The attachable element consists of a cord or the like, the free end of which is equipped with a clamped ring. This ring is in the niche. Applying new keys or removing a key from the bendable element requires great dexterity. You have to keep the clamped end ring of the bendable element clean, especially in the niche, until you have pushed the slider back into the sleeve enough. This handling would be made even more difficult if the slide would not carry such bendable elements on both ends, so that it cannot be pulled back into the sleeve into its latching position with the opposite bendable element.

Aufgabe der vorliegenden Erfindung ist es, einen gattungsgemäßen Schlüsselanhänger so auszugestalten, daß bei vereinfachter Herstellung eine erleichterte Bedienung gegeben ist, insbesondere im Hinblick auf ein leichtes Anbringen der Schlüssel und Abnehmen derselben vom biegbaren Element.The object of the present invention is to design a generic key fob in such a way that it is easier to operate with simplified manufacture, in particular with regard to easy attachment of the key and removal of the key from the bendable element.

Gelöst ist diese Aufgabe durch die im Kennzeichen des Hauptanspruches angegebene Erfindung.This object is achieved by the invention specified in the characterizing part of the main claim.

Zufolge dieser Ausgestaltung ist ein lediglich zweiteilig und damit leicht produzierbarer Schlüsselanhänger geschaffen mit erheblichen Gebrauchsvorteilen. Die für die Verrastung des Schiebers in der Hülse ausgenutzte elastische Rückstellkraft des Schiebermateriales ist gleichzeitig benutzt, um den das biegbare Element bildenden elastischen Bügel selbsttätig nach Ausbiegung desselben -zum Aufbringen oder Abnehmen eines Schlüssels- wieder in die Grundstellung zurücktreten zu lassen. In dieser Grundstellung liegt dann das freie Ende dieses Bügels in der Nische. Ohne Angriff irgendwelcher Betätigungskräfte befindet sich also der Bügel grundsätzlich in seiner Grundstellung und damit in derjenigen Stellung, in welcher der Schieber in die Hülse eingeschoben werden kann, um die Nische zu verschließen, was zur allseitigen Fesselung des freien Endes des Bügels führt. Zufolge der Tatsache, daß die Hülse eine Öffnung hat, durch welche man hindurchgreifen muß, um die Drucktastenfläche des plattenförmigen Schiebers aus der Raststellung in die Freigabestellung zu drücken, ergibt sich auch noch der Vorteil, daß man den Schieber mit demselben druckbetätigten Finger leicht nach vorne aus der Hülse jedenfalls so weit herausschieben kann, bis die Nische freiliegt. Man hat mit dem druckbetätigenden Finger den Schieber dann noch in der Gewalt, während man mit den Fingern der anderen Hand den Bügel aus seiner Grundstellung ausbiegen kann, um Schlüssel aufzubringen oder abzunehmen.As a result of this configuration, a key fob, which is only made in two parts and is therefore easy to produce, is created with considerable advantages in use. The elastic restoring force of the slide material, which is used for the locking of the slide in the sleeve, is used at the same time to automatically return the elastic bracket forming the bendable element to the basic position after the latter has been bent out - for application or removal of a key. In this basic position, the free end of this bracket is in the niche. Without attacking any actuation forces, the bracket is basically in its basic position and thus in the position in which the slide can be inserted into the sleeve to close the recess, which leads to all-round tying of the free end of the bracket. Due to the fact that the sleeve has an opening through which it is necessary to reach through in order to press the push-button surface of the plate-shaped slide from the locked position into the release position, there is also the advantage that the slide can be moved slightly forward with the same pressure-actuated finger can slide out of the sleeve until the niche is exposed. With the pressure-actuating finger, you still have the slider under control, while you can use the fingers of the other hand to bend the bracket out of its basic position in order to apply or remove keys.

Bei Gürtelschnallen ist es bereits bekannt (DE-A-23 42 208) das eine Schnallenteil als plattenförmigen Schieber auszubilden. Aus dessen Breitfläche ragt schräg ansteigend eine Drucktastenfläche hervor. Der plattenförmige Schieber wird in eine Hülse eingeschoben. Diese besitzt Flachform und hat eine Durchgreiföffnung, um die Drucktastenfläche aus der Verrastung am Rand der Durchgreiföffnung zu bringen. Abgesehen davon, daß es sich bei diesen Lösungen nicht um Schlüsselanhänger handelt, fehlt der der Erfindung zugrundeliegende grundsätzliche Gedanke, die für solche materialeinheitlich angeformten Drucktastenflächen notwendige elastische Rückstellkraft des Materiales gleichzeitig auszunutzen, um einen Bügel zum Befestigen irgendwelcher Teile aus einer ausgebogenen Stellung stets wieder elastisch in eine Grundstellung zurücktreten zu lassen, in welcher er in einer dreiseitig offenen Nische liegt, welche nach Einschieben in eine Hülse allseitig verschlossen ist. Daneben sind auch noch Schlüsselanhänger bekannt (US-A-40 79 607), bei denen ein plattenförmiger Schieber einen angeformten Bügel zum Aufreihen von Schlüsseln ausbildet, und zwar materialeinheitlich. Das freie Ende des Schiebers ragt in eine Nische des plattenförmigen Schiebers. Dies erfolgt jedoch nicht in einem Hintergriff. Zwischen Randkante der Nische und freiem Ende des Bügels verbleibt vielmehr ein erheblicher freier Spalt zum Durchfädeln des aufzureihenden Schlüssels. Der plattenförmige Schieber ist eingeschoben in eine Hülse. Diese verdeckt auch die Nische, verschließt sie aber nicht. Der Bügel ist deshalb in sich so stabil, daß er sich nicht aus der Hülse herausbiegt unter Freigabe etwaiger Schlüssel, auch bei deren Betätigung. Der plattenförmige Schieber ist von einer zusätzlichen Druckfeder in Richtung eines Einziehens in die Hülse belastet. Zum Auffädein neuer Schlüssel muß man den Schieber entgegen dieser Druckfeder aus der Hülse herausziehen, mit viel Fingerfertigkeit in dieser Stellung festhalten, um dann durch den Spalt zwischen Nische und freiem Ende des Bügels einen neuen Schlüssel einzufädeln. Läßt man dann den Schieber wieder los, so zieht die Feder ihn zurück in die Hülse. Die zusätzliche verwendete Druckfeder ist auch montagetechnisch nachteilig. Im übrigen besteht auch die Gefahr, daß sich der Schieber beim Tragen oder Bedienen des Schlüssels unerwünscht aus der Hülse verlagert und sich eventuell sogar ein Schlüssel ausfädeln.With belt buckles it is already known (DE-A-23 42 208) to design the one buckle part as a plate-shaped slide. A pushbutton surface protrudes from its wide surface. The plate-shaped slide is inserted into a sleeve. This has a flat shape and has a reach-through opening in order to bring the pushbutton surface out of the catch at the edge of the reach-through opening. Apart from the fact that these solutions are not key fobs, the basic idea underlying the invention is lacking at the same time to utilize the elastic restoring force of the material which is necessary for such pushbutton surfaces molded onto the same material, in order to always resiliently secure a bracket for fastening any parts from a bent position to step back into a basic position in which it lies in a niche open on three sides, which is closed on all sides after insertion into a sleeve. In addition, key fobs are also known (US-A-40 79 607), in which a plate-shaped slider forms an integrally formed bracket for the arrangement of keys, in a uniform material. The free end of the slide projects into a recess of the plate-shaped slide. However, this is not done in a backhand. Rather, there is a considerable free gap between the edge of the niche and the free end of the bracket for threading the key to be lined up. The plate-shaped slide is inserted into a sleeve. This also covers the niche, but does not close it. The bracket is therefore so stable in itself that it does not bend out of the sleeve with the release of any keys, even when they are actuated. The plate-shaped slide is loaded by an additional compression spring in the direction of retraction into the sleeve. To thread new keys you have to pull the slide against this compression spring out of the sleeve, hold it with great dexterity in this position, then thread a new key through the gap between the niche and the free end of the bracket. If you then let go of the slide, the spring pulls it back into the sleeve. The additional compression spring used is also disadvantageous in terms of assembly. In addition, there is also the risk that the slider undesirably moves out of the sleeve when the key is being carried or operated, and that a key may even be threaded out.

Eine vorteilhafte Weiterbildung der Erfindung besteht darin, daß der Bügel über die Längsseitenkante des Flachhülsen-Schachtes vorsteht.An advantageous development of the invention is that the bracket protrudes over the longitudinal side edge of the flat sleeve shaft.

Der Sicherheitswert des Schlüsselanhängers ist dadurch erhöht, daß die Nische winkelförmig gestaltet ist und sich ein Schenkel quergerichtet zur Einsteckrichtung der Platte erstreckt. Ist der Bügel mit Platte der Flachhülse zugeordnet, so kann auch durch größere Krafteinwirkung auf den Bügel der quergerichtete Schenkel nicht aus der Nische herausbewegt werden.The security value of the key fob is increased by the fact that the niche is angular and one leg is transverse extends to the direction of insertion of the plate. If the bracket with plate is assigned to the flat sleeve, the transverse leg cannot be moved out of the niche even by exerting greater force on the bracket.

Bei Herstellung der Platte mit Bügel aus Kunststoff mit entsprechenden federnden Eigenschaften ist es von Vorteil, daß ein abgewinkelter Abschnitt des Bügels mit Spiel in dem quergerichteten Nischen-Schenkel einliegt. Hierbei erweist es sich als günstig, daß das Spiel durch vorstehende Spitzen der Nischenwand begrenzt ist. Diese können beim Spritzvorgang miterzeugt werden.When manufacturing the plate with a bracket made of plastic with corresponding resilient properties, it is advantageous that an angled section of the bracket rests with play in the transverse niche leg. It proves to be favorable that the game is limited by protruding tips of the niche wall. These can be created during the spraying process.

Eine vorteilhafte Bauform besteht fernerhin darin, daß die Drucktastenfläche einen Anschlag besitzt, der gegen den Rand der Öffnung der Flachhülsenwand stößt. Dies vergrößert die Verrastungsfestigkeit erheblich. Darüber hinaus besteht ein vorteilhaftes Merkmal darin, daß der plattenförmige Schieber an seiner einschubseitigen Stirnkante gerundet gestaltet ist und Federzungen besitzt, die sich gegen den Boden des Schachtes der Flachhülse anlegen. In der Einsteck-Endstellung stehen die Federzungen unter Spannung und bewirken eine feste, wackelfreie Anlage des eingeschobenen plattenförmigen Schiebers. Das mit den Federzungen versehene gerundete Ende gestattet ein leichtes Einführen des plattenförmigen Schiebers in die Hülse. Eine weitere Variante der Erfindung ist gegeben durch zwei in eine Flachhülse in entgegengesetzte Richtungen einschiebbare plattenförmige Schieber. Bei einer Abwandlung dieser Bauform ist es günstig, wenn die beiden plattenförmigen Schieber sich überlappen. Dies bringt bei gleich großem Bedienungsvorteil eine kleinere Bauform.An advantageous design is also that the push button surface has a stop that abuts the edge of the opening of the flat sleeve wall. This increases the locking strength considerably. In addition, there is an advantageous feature that the plate-shaped slide is rounded on its insert-side end edge and has spring tongues which bear against the bottom of the shaft of the flat sleeve. In the inserted end position, the spring tongues are under tension and ensure a firm, wobble-free contact of the inserted plate-shaped slide. The rounded end provided with the spring tongues allows the plate-shaped slide to be easily inserted into the sleeve. Another variant of the invention is provided by two plate-shaped slides which can be inserted into a flat sleeve in opposite directions. In a modification of this design, it is advantageous if the two plate-shaped slides overlap. This results in a smaller design with the same operating advantage.

Gemäß der ersten Ausführungsform besitzt der Schlüsselanhänger eine aus Kunststoff gefertigte Flachhülse 1. Diese setzt sich zusammen aus den beiden Breitseitenwänden 11 und 12, den Längsseitenwänden 13 und 14 sowie dem Boden 15. Auf diese Weise ist ein Schacht 16 gebildet.According to the first embodiment, the key fob has a flat sleeve 1 made of plastic. This is composed of the two broad side walls 11 and 12, the longitudinal side walls 13 and 14 and the bottom 15. In this way, a shaft 16 is formed.

Die Breitseitenwände 11, 12 der Flachhülse 1 sind im Bereich der Schachtmündung zu einer Kehle 17 geformt, die in schräg in die Längsseitenwände einlaufende Abschnitte 18 übergeht.The wide side walls 11, 12 of the flat sleeve 1 are formed in the region of the shaft mouth to form a throat 17 which merges into sections 18 which run obliquely into the longitudinal side walls.

In der einen Breitseitenwand 11 befindet sich eine im Querschnitt kreisförmige Einschnapp- Öffnung 2.In one broad side wall 11 there is a snap-in opening 2 with a circular cross section.

Vom Boden 15 der Flachhülse 1 gehen symmetrisch zur Symmetrielinie der Flachhülse 1 Stützrippen 19 aus, die die beiden Breitseitenwände 11, 12 miteinander verbinden und mit Abstand vor der Einschnapp-Öffnung 2 enden.Support ribs 19, which connect the two broad side walls 11, 12 and end at a distance in front of the snap-in opening 2, extend from the base 15 of the flat sleeve 1 symmetrically to the line of symmetry of the flat sleeve 1.

Die Flachhülse 1 wirkt zusammen mit einer in diese einzuschiebenden Platte 3. Diese besteht ebenfalls aus geeignetem Kunststoff. Von der einen Randkante 20 der Platte geht ein elastischer Bügel 6 aus. Dieser formt in Verbindung mit der Platte 3 eine ovale Öffnung 21. Der Bügel 6 endet in einen quer zur Einschubrichtung der Platte abgewinkelten Abschnitt 7, der sich an einen geradlinigen Abschnitt 22 des Bügels 6 anschließt. Der geradlinige Abschnitt 22 seinerseits erstreckt sich auf Höhe der der Randkante 20 gegenüberliegenden Randkante 23.The flat sleeve 1 interacts with a plate 3 to be inserted therein. This also consists of a suitable plastic. An elastic bracket 6 extends from one edge 20 of the plate. This forms an oval opening 21 in connection with the plate 3. The bracket 6 ends in a section 7 which is angled transversely to the insertion direction of the plate and which adjoins a rectilinear section 22 of the bracket 6. The rectilinear section 22 in turn extends at the level of the edge 23 opposite the edge 20.

Der geradlinige Abschnitt 22 und der abgewinkelte Abschnitt 7 ragen in eine winkelförmig gestaltete Nische 24 der Platte derart, daß der geradlinige Abschnitt 22 des Bügels in dem einen Schenkel 24' und der abgewinkelte Abschnitt 7 in dem Nischen-Schenkel 24" mit Spiel einliegt. Zur Begrenzung des Spiels sind an der Nischenwand drei vorstehende Spitzen 25, 26 und 27 vorgesehen. Die Spitzen 25, 27 liegen einander gegenüber und erstrecken sich in Einsteckrichtung, während die Spitze 26 der Stirnkante des abgewinkelten Abschnitts 7 zugekehrt ist.The rectilinear section 22 and the angled section 7 protrude into an angled recess 24 of the plate such that the rectilinear section 22 of the bracket lies in one leg 24 'and the angled section 7 in the niche leg 24 "with play To limit the play, three projecting tips 25, 26 and 27 are provided on the niche wall. The tips 25, 27 lie opposite one another and extend in the insertion direction, while the tip 26 faces the front edge of the angled section 7.

Die Platte 3 enthält auf ihrem einsteckseitigen Ende eine als Drucktaste ausgebildete Rastklinke 8. Diese ist als freigeschnittene, aus der Plattenebene schräg in Richtung des Bügels 6 ansteigend vorstehende Kreisfläche gebildet. Der Freischnitt erstreckt sich über einen Winkelbetrag derart, daß die Materialbrücke dem einsteckseitigen Ende der Platte zugekehrt ist. Im Bereich der Materialbrücke ist durch eine quer zur Einsteckrichtung verlaufende Nut 30 ein Scharnier gebildet, um welches die Rastklinke schwenkbar ist.The plate 3 contains on its plug-in end a locking pawl 8 designed as a pushbutton. This is formed as a cut circular surface protruding from the plane of the plate obliquely in the direction of the bracket 6. The free cut extends over an angular amount in such a way that the material bridge faces the plug-in end of the plate. In the area of the material bridge, a hinge is formed by a groove 30 running transversely to the direction of insertion, about which the latch can be pivoted.

Die Rastklinke 8 weist an dem der Nut 30 gegenüberliegenden Rand R einen bogenförmig verlaufenden Anschlag 31 auf.The detent pawl 8 has an arcuate stop 31 on the edge R opposite the groove 30.

Wie die Zeichnungen erkennen lassen, ist die Platte 3 an ihrer einschubseitigen Stirnkante 32 gerundet gestaltet und besitzt dort zwei Federzungen 33, 34, die durch einen bogenförmigen Längsschlitz 35 geformt sind.As can be seen from the drawings, the plate 3 is rounded on its insert-side end edge 32 and there has two spring tongues 33, 34 which are shaped by an arcuate longitudinal slot 35.

Aus Fig. 2 ist zu entnehmen, daß der Bügel 6 über die Randkanten 20, 23 der Platte 3 vorsteht. Der Abstand zwischen den beiden Randkanten 20, 23 ist etwas geringer als das Maß zwischen den beiden Längsseitenkanten des Schachtes 16.From Fig. 2 it can be seen that the bracket 6 protrudes over the edge edges 20, 23 of the plate 3. The distance between the two peripheral edges 20, 23 is slightly less than the dimension between the two longitudinal side edges of the shaft 16.

Sollen der Platte 3 Schlüssel zugeordnet werden, so ist der elastisch verformbare Bügel 6 so zu verschwenken, daß der abgewinkelte Abschnitt 7 des Bügels 6 die Nische 24 verläßt. Es können dann die Schlüssel aufgereiht werden. Nach Loslassen des Bügelendes kehrt der Abschnitt 7 in die Nische 24 zurück. Es kann nun die Platte 3 eingeschoben werden. In der Einsteck-Endstellung beaufschlagen die Federzungen 33, 34 die vom Boden 15 der Flachhülse ausgehenden Stege 19, während die Rastklinke 8 in die Einschnapp-Öffnung 2 der Flachhülse eintaucht. Die Federzungen 33, 34 bewirken nun, daß die Rastklinke 8 mit ihrem dem Bügel 6 zugekehrten Rand R in Anlage zum Wandungsabschnitt 2' der Einschnappöffnung 2 gelangt. In dieser Stellung befindet sich der Anschlag 31 der Rastklinke unterhalb des Wandungsabschnitts 2', so daß sie nicht aus der Öffnung 2 herausschwenken kann, vergl. insbesondere Fig.6.3 keys should be assigned to the plate are, the elastically deformable bracket 6 is pivoted so that the angled portion 7 of the bracket 6 leaves the recess 24. The keys can then be lined up. After releasing the temple end, section 7 returns to recess 24. The plate 3 can now be inserted. In the inserted end position, the spring tongues 33, 34 act on the webs 19 extending from the bottom 15 of the flat sleeve, while the latching pawl 8 plunges into the snap-in opening 2 of the flat sleeve. The spring tongues 33, 34 now cause the latch 8 with its edge R facing the bracket 6 to come into contact with the wall section 2 'of the snap-in opening 2. In this position, the stop 31 of the latch is located below the wall section 2 ', so that it cannot pivot out of the opening 2, cf. in particular FIG. 6.

In der Einsteck-Endstellung liegt die Nische 24 im Bereich des Schachtes 16 der Flachhülse. Das bedeutet, daß der abgewinkelte Abschnitt 7 des Bügels 6 gegen jedes Herausschwenken gesichert ist, vergl. hierzu Fig. 5.In the insertion end position, the recess 24 is located in the area of the shaft 16 of the flat sleeve. This means that the angled section 7 of the bracket 6 is secured against any pivoting out, cf. FIG. 5.

Das Abnehmen der Platte 3 von der Flachhülse 1 erfordert ein Beaufschlagen der Rastklinke 8 in Einwärtsrichtung. Hierbei müssen die Kräfte der Federzungen 33, 34 überwunden werden.The removal of the plate 3 from the flat sleeve 1 requires loading of the latch 8 in the inward direction. The forces of the spring tongues 33, 34 must be overcome.

Erst wenn die Rastklinke vollständig aus der Öffnung 2 der Flachhülse 1 herausgetreten ist, kann die Platte 3 herausgezogen werden.Only when the latch has completely emerged from the opening 2 of the flat sleeve 1 can the plate 3 be pulled out.

Die in Fig. 7 dargestellte zweite Ausführungsform besitzt eine abgewandelte Flachhülse 36. Diese ist etwa doppelt so lang ausgebildet wie die Flachhülse 1. An den einander entgegengesetzten Seiten der Flachhülse 36 befinden sich ähnlich gestaltete Schächte. Ferner sind an einer Breitseitenwand 37 Einschnapp-Öffnungen 2 vorgesehen, die mit den Rastklinken 8 der einzusteckenden Platten 3 zusammenwirken. Auch enthält die Flachhülse 36 bei dieser Ausführungsform nicht dargestellte Stege, die die Federzungen 33, 34 der Platten 3 beaufschlagen.The second embodiment shown in FIG. 7 has a modified flat sleeve 36. This is approximately twice as long as the flat sleeve 1. On the opposite sides of the flat sleeve 36 there are similarly shaped shafts. Furthermore, snap-in openings 2 are provided on a broad side wall 37, which cooperate with the latches 8 of the plates 3 to be inserted. In this embodiment, the flat sleeve 36 also contains webs, not shown, which act on the spring tongues 33, 34 of the plates 3.

Bei der dritten Ausführungsform nach den Fig.8 und 9 können in eine Flachhülse 38 ebenfalls Platten 3 in entgegengesetzten Richtungen eingeschoben werden. Die Flachhülse 38 enthält zu diesem Zweck zwei parallel zueinander liegende, von entgegengesetzten Richtungen ausgehende Schächte 39, 40, die durch eine Zwischenwand 41 voneinander getrennt sind. Auf den äußeren Breitseitenwänden der Flachhülse 38 sind die Einschnapp-Öffnungen 2 vorgesehen, die mit den Rastklinken 8 der Platten 3 zusammenwirken.In the third embodiment according to FIGS. 8 and 9, plates 3 can also be inserted into a flat sleeve 38 in opposite directions. For this purpose, the flat sleeve 38 contains two shafts 39, 40 lying parallel to one another and extending from opposite directions, which are separated from one another by an intermediate wall 41. On the outer broad side walls of the flat sleeve 38, the snap-in openings 2 are provided, which cooperate with the latches 8 of the plates 3.
