Description

Die Erfindung bezieht sich auf Zugangseinrichtungen für Kraftfahrzeuge, und betrifft insbesondere die Verwahrung des Notschlüssels in einem Identifikationsgeber einer elektronischen Zugangsanordnung.The invention relates to access devices for motor vehicles, and more particularly relates to the storage of the emergency key in an identification transmitter of an electronic access device.

Zum Verhindern eines nicht autorisierten Zugangs zu bestimmten Gegenständen, wie beispielsweise Räumen, Fahrzeugen oder anderen Systemen, werden neben mechanischen Schließsystemen zunehmend elektronische, so genannte schlüssellose Zugangssysteme verwendet. Vor allem bei Kraftfahrzeugen werden derartige Zugangssysteme verwendet, um den Zugang zum Fahrzeuginneren, wie beispielsweise zur Fahrgastzelle, zum Kofferraum oder zu anderen nach außen abschließbaren Räumen des Fahrzeugs aber auch zum Startsystem des Fahrzeugs auf den befugten Benutzerkreis zu beschränken.In order to prevent unauthorized access to certain objects, such as rooms, vehicles or other systems, in addition to mechanical locking systems increasingly electronic, so-called keyless entry systems are used. Especially in motor vehicles such access systems are used to restrict access to the vehicle interior, such as the passenger compartment, the trunk or other lockable rooms outside of the vehicle but also to the starting system of the vehicle to the authorized group of users.

Bei diesen meist funkbasierten Zugangssystemen muss der Zugangsberechtigte lediglich einen Identifikationsgeber mit sich führen, der die Authentifizierung des Benutzers über eine Kommunikationsverbindung mit dem Kraftfahrzeug vornimmt. Nach erfolgreicher Authentifizierung wird dem Benutzer in der Regel der Zugang zum Fahrzeuginneren oder bestimmten Fahrzeugsystemen gewährt.In these mostly radio-based access systems, the authorized user only has to carry with him an identification transmitter which carries out the authentication of the user via a communication link with the motor vehicle. After successful authentication, the user is usually granted access to the vehicle interior or certain vehicle systems.

Um den Zugang zum Fahrzeug und eventuell anderen Systemen des Fahrzeugs auch bei einem Ausfall des elektronischen Zugangssystems zu ermöglichen, sind in der Regel eine oder mehrere mechanische Schließvorrichtungen vorgesehen, die mithilfe eines mechanischen Schlüssels, dem so genannten Notschlüssel, betätigt werden können. Damit der Notschlüssel im Notfall auch stets verfügbar ist, bilden Notschlüssel und Identifikationsgeber des elektronischen Zugangssystems im Allgemeinen eine mechanische Einheit. Der Notschlüssel sollte dabei sicher innerhalb eines die mechanische Einheit nach außen abgrenzenden Gehäuses angeordnet sein, um Beschädigungen von z.B. empfindlichen Oberflächen oder Textilien durch den Schlüssel zu vermeiden, und er sollte ohne Werkzeug aus dem Gehäuse entnommen werden können.
Üblicherweise kann der Schlüssel hierzu seitlich in das Gehäuse des Identifikationsgebers eingeführt oder eingeschwenkt werden, wobei er in seiner Endlage innerhalb des Gehäuses mittels einer Verriegelung lösbar gesichert werden kann. Ein unachtsames Berühren oder ein Herabfallen des den Notschlüssel aufnehmenden Identifikationsgebers kann, wie auf dessen Gehäuse einwirkende mechanischen Erschütterungen auch, zu einer unbeabsichtigten Entriegelung des Notschlüssels in dem Gehäuse mit der Folge führen, dass der Notschlüssel sich zumindest teilweise außerhalb des Gehäuses befindet und dadurch andere Sachen beschädigen kann. Wird der Schlüssel in das Gehäuse nur eingeschoben, kann es sogar zum Verlust des Notschlüssels kommen.
Die Einheit aus elektronischem Identifikationsgeber und Notschlüssel muss ferner auf ein Bauvolumen beschränkt werden, das es vor allem männlichen Benutzern gestattet, den Gegenstand in Kleidungstaschen mitzuführen, ohne dass das optische Erscheinungsbild der Kleidung durch ein "Ausbeulen" der Tasche oder Ähnliches beeinträchtigt wird. Dies ist nur möglich, wenn die Größe des Notschlüssels auf das für seine Schließfunktion erforderliche Maß beschränkt wird. Aus der US 2004/085211 und aus der JP 2006 132271 sind eine Vorrichtung zur Verwahrung eines Schlüssels für mechanische Schliessvorrichtungen eines elektronischen Zugangssystems bekannt, mit einem Grundgehäuse und einer Gehaüseabdeckung, wobei der Verschlussmechanismus einen gelenkigen Verbindungsmechanismus umfasst. Der Erfindung liegt daher die Aufgabe zugrunde, ein Gehäuse für einen Identifikationsgeber eines elektronischen Zugangssystems anzugeben, in dem der Notschlüssel sicher aufbewahrt werden kann, das eine kompakte Ausführung des Notschlüssels ermöglicht und ein unbeabsichtigtes Herausfallen des Schlüssels effektiv unterbindet. Diese Aufgabe wird durch den Gegenstand des unabhängigen Anspruchs gelöst.In order to allow access to the vehicle and possibly other systems of the vehicle even in case of failure of the electronic access system, one or more mechanical locking devices are usually provided, which can be operated by means of a mechanical key, the so-called emergency key. So that the emergency key is always available in an emergency, emergency keys and identification transmitter of the electronic access system generally form a mechanical unit. The emergency key should be safe be disposed within a housing outwardly delimiting the mechanical unit to prevent damage to eg sensitive surfaces or textiles by the key, and he should be removed without tools from the housing.
Usually, the key can be laterally inserted or pivoted into the housing of the identification transmitter, wherein it can be releasably secured in its end position within the housing by means of a lock. Careless touching or falling of the emergency key receiving the identification transmitter, as well as acting on the housing mechanical shocks, lead to an inadvertent unlocking of the emergency key in the housing with the result that the emergency key is at least partially outside the housing and other things can damage. If the key is inserted into the housing, it may even lead to the loss of the emergency key.
The unit of electronic identification transmitter and emergency key must also be limited to a volume of construction, which allows especially male users to carry the item in clothes bags, without the visual appearance of the clothing is affected by a "bulging" of the bag or the like. This is only possible if the size of the emergency key is limited to what is necessary for its closing function. From the US 2004/085211 and from the JP 2006 132271 For example, a device for storing a key for mechanical locking devices of an electronic access system is known, comprising a base housing and a housing cover, wherein the locking mechanism comprises a hinged connection mechanism. The invention is therefore based on the object of specifying a housing for an identification transmitter of an electronic access system, in which the emergency key can be safely stored, which allows a compact version of the emergency key and effectively prevents unintentional falling out of the key. This object is solved by the subject matter of the independent claim.

Die Erfindung umfasst eine Vorrichtung zur Verwahrung eines Schlüssels für eine mechanische Schließvorrichtungen eines elektronischen Zugangssystems mit einem Grundgehäuse, das zur Aufnahme des Schlüssels ausgebildet ist, einer Gehäuseabdeckung zur Abdeckung des in dem Grundgehäuse aufgenommenen Schlüssels und einem Verschlussmechanismus zur lösbaren Verbindung von Grundgehäuse und Gehäuseabdeckung. Der Verschlussmechanismus umfasst hierbei eine gelenkige Verbindungseinrichtung und eine von der gelenkigen Verbindungseinrichtung beabstandete Verriegelungseinrichtung.
Die Erfindung ermöglicht eine stoßunempfindliche sichere Verwahrung eines Notschlüssels innerhalb eines Gehäuses für einen Identifikationsgeber eines elektronischen Zugangssystems. Die Ausführung des Gehäuseverschlusses mit zwei Verbindungseinrichtungen verhindert eine unbeabsichtigte Schlüsselfreigabe, die zum Verlust des Schlüssels oder zur Beschädigung von Gegenständen führen könnte, die mit dem offen zugänglichen Schlüssel in Kontakt kommen. Erfindunsgemäß umfasst die gelenkige Verbindungseinrichtung vorzugsweise einen Haken an der Gehäuseabdeckung und an geeigneter Stelle des Grundgehäuses eine Öffnung in dessen Oberfläche, wobei der Haken zum Untergreifen der Oberfläche des Grundgehäuses an einer Kante der Öffnung ausgebildet ist. Alternativ oder ergänzend kann die gelenkige Verbindungseinrichtung auch einen Haken an dem Grundgehäuse und eine Öffnung in einer Oberfläche der Gehäuseabdeckung umfassen, wobei auch hierbei der Haken zum Untergreifen der Oberfläche der Gehäuseabdeckung an einer Kante der Öffnung ausgebildet ist. Ein unbeabsichtigtes Herausfallen des Schlüssels wird effektiv unterbunden, weil die gelenkige Verbindungseinrichtung nur für einen begrenzten Schwenkwinkel der Gehäuseabdeckung ausgebildet ist.The invention comprises a device for storing a key for a mechanical locking devices of an electronic access system having a base housing which is adapted to receive the key, a housing cover for covering the key received in the main housing and a locking mechanism for releasably connecting the base housing and the housing cover. The closure mechanism here comprises an articulated connection device and a locking device spaced from the articulated connection device.
The invention enables shock-resistant secure storage of an emergency key within a housing for an identification transmitter of an electronic access system. The design of the housing closure with two connectors prevents inadvertent key release, which could lead to the loss of the key or damage to objects that come into contact with the open key. According to the invention, the articulated connection device preferably comprises a hook on the housing cover and, at a suitable location of the base housing, an opening in its surface, the hook being designed to engage the surface of the base housing at an edge of the opening. Alternatively or additionally, the articulated connection means may also comprise a hook on the base housing and an opening in a surface of the housing cover, wherein in this case the hook is formed for engaging under the surface of the housing cover at an edge of the opening. An accidental falling out of the key is effectively prevented because the articulated Connecting device is designed only for a limited tilt angle of the housing cover.

Zum sicheren Verschließen des Gehäuses weist die Verriegelungseinrichtung zweckmäßig wenigstens einen Riegel auf, der zum Untergreifen einer Gehäusekante ausgebildet ist. Ein stabiles und dennoch ohne großen Aufwand lösbares Untergreifen der Gehäusekante wird bevorzugt mit einem Riegel erzielt, der einen elastischen Abschnitt und ein Kopfende aufweist, das zum Untergreifen einer Gehäusekante ausgebildet ist. Zum Lösen des Untergreifen weist die Verriegelungseinrichtung günstigerweise wenigstens ein Öffnungselement auf, das gegen das Kopfende des Riegels verschiebbar angeordnet ist. Damit die Gehäuseabdeckung nach dem durch das Lösen des Untergreifens bewirkten Entriegeln der Verriegelungseinrichtung vom Grundgehäuse abgehoben werden kann, weisen das Kopfende des Riegels und das Öffnungselement bevorzugt jeweils eine Fläche auf, die durch ein Verschieben des Öffnungselements in Kontakt gebracht werden können und die zur Verschieberichtung des Öffnungselements in einen Winkel orientiert sind, der bei Kontakt beider Flächen eine Aufteilung der auf das Öffnungselement ausgeübten Verschiebekraft mit einer Kraftkomponente in Richtung der Gehäusekante bewirkt.For securely closing the housing, the locking device expediently has at least one latch, which is designed to engage under a housing edge. A stable and yet easily detachable under gripping the housing edge is preferably achieved with a bolt having an elastic portion and a head end, which is designed to engage under a housing edge. For releasing the undergrip, the locking device conveniently has at least one opening element, which is arranged displaceably against the head end of the bolt. In order for the housing cover to be lifted off the base housing after the unlocking of the locking device caused by loosening of the lower grip, the head end of the lock and the opening element preferably each have a surface which can be brought into contact by displacement of the opening element and which corresponds to the displacement direction of the opening element Opening element are oriented in an angle which causes a distribution of the force exerted on the opening element displacement force with a force component in the direction of the housing edge on contact of both surfaces.

In einer vorteilhaften Weiterentwicklung umfasst die Verriegelungseinrichtung vorzugsweise ein Federelement zum Verbringen des Öffnungselements in eine Ruhelage. Ferner kann die Verriegelungseinrichtung zur Verbesserung der Bedienbarkeit ein Griffelement umfassen, das zur Aufnahme einer von einem Benutzer auf es ausgeübten Druckkraft und zur Weiterleitung dieser Druckkraft in Form einer Verschiebekraft auf das Öffnungselement ausgebildet ist. In einer bevorzugten Ausführungsform sind Öffnungselement, Griffelement und Federelement einstückig ausgebildet, um eine kostengünstige und einfach montierbare Verriegelungseinrichtung zu realisieren.In an advantageous further development, the locking device preferably comprises a spring element for bringing the opening element into a rest position. Further, the locking device may include a handle member for improving the operability, which is adapted to receive a pressure force exerted by a user on it and for forwarding this pressure force in the form of a displacement force on the opening element. In a preferred embodiment, opening element, handle element and spring element are integrally formed in order to realize a cost-effective and easily assembled locking device.

Vorteilhaft weist das Grundgehäuse eine Vertiefung zur Aufnahme des Schlüssels auf, die den Schlüssel innerhalb des Gehäuses in einer ortsfesten Lage hält und ihn so darin verwahrt. Weiterhin kann die Vertiefung einen Eingriffsbereich aufweisen, der an den Bereich zur Aufnahme des Schlüssels angrenzt und hierüber ein einfaches Entnehmen des Schlüssels durch einen Benutzer, beispielsweise mit einem Finger, ermöglicht. Für ein definiertes Herausschwenken des Schlüssels aus der Vertiefung, wodurch insbesondere ein Herausfallen des Schlüssels aus dieser vermieden wird, weist die Vertiefung vorzugsweise einen Endbereich mit einer Überdeckung auf.Advantageously, the base housing has a recess for receiving the key, which holds the key within the housing in a stationary position and thus stores it therein. Furthermore, the depression can have an engagement region which adjoins the region for receiving the key and makes possible a simple removal of the key by a user, for example with a finger. For a defined swinging out of the key from the recess, whereby in particular falling out of the key is avoided from this, the recess preferably has an end portion with a cover.

Um ein höheres Schließdrehmoment zu erzeugen kann das Gehäuse in einer vorteilhaften Weiterentwicklung als Schlüsselkopferweiterung genutzt werden. Hierzu umfasst die Vertiefung einen Bereich, der zur Aufnahme des Schlüsselkopfs bei einer Anordnung des Schlüssels in einem mehr oder weniger rechten Winkel zu seiner Verwahrungsstellung in der Vertiefung ausgebildet istIn order to produce a higher closing torque, the housing can be used in an advantageous development as a key head extension. For this purpose, the recess comprises an area which is formed for receiving the key head in an arrangement of the key at a more or less right angle to its storage position in the recess

Figur 1 zeigt eine perspektivische Ansicht eines Gehäuses 1, das ein Grundgehäuse 2 und eine abnehmbare Gehäuseabdeckung 3 umfasst. Das Gehäuse 1 ist in einem geöffneten Zustand dargestellt und zeigt den in der mit der Gehäuseabdeckung 3 verschließbaren Gehäuseöffnung 4 eingelegten Notschlüssel 5. Die Konstruktion des Grundgehäuses 2 und der Gehäuseabdeckung 3 sind vorzugsweise so aufeinander abgestimmt, dass die Abdeckung 3 im geschlossenen Zustand des Gehäuses 1 bündig mit dem Grundgehäuse abschließt. Ferner kann die Außenfläche der Gehäuseabdeckung 3, d.h. deren bei geschlossenem Gehäuse nach außen weisende Oberfläche, ein Dekorelement aufweisen oder für das Anbringen eines Dekorelements vorbereitet sein. FIG. 1 shows a perspective view of a housing 1, which comprises a base housing 2 and a removable housing cover 3. The housing 1 is shown in an open state and shows the in the closable with the housing cover 3 housing opening 4 emergency key 5. The construction of the base housing 2 and the housing cover 3 are preferably coordinated so that the cover 3 in the closed state of the housing. 1 flush with the base housing. Furthermore, the outer surface of the housing cover 3, ie its surface facing outwardly when the housing is closed, may have a decorative element or be prepared for the attachment of a decorative element.

Zur Aufnahme des Notschlüssels 5 ist in der Gehäuseöffnung 4 eine Vertiefung 6 angeordnet, deren Seitenwände sich von der oberen Fläche der Gehäuseöffnung 4 zum Boden der Vertiefung 6 erstrecken. Die über die Seitenwände definierte Umrissgeometrie der Vertiefung 6 ist dabei so an die Form des Notschlüssels 5 angepasst, dass eine laterale Bewegung des in der Vertiefung 6 liegenden Schlüssels ausgeschlossen oder zumindest stark eingeschränkt ist. Damit wird ein Klappern des Notschlüssels 5 im Gehäuse unterbunden.For receiving the emergency key 5, a recess 6 is arranged in the housing opening 4, the side walls extending from the upper surface of the housing opening 4 to the bottom of the recess 6. The defined over the side walls outline geometry of the recess 6 is adapted to the shape of the emergency key 5 that a lateral movement of lying in the recess 6 key is excluded or at least greatly limited. This rattle the emergency key 5 is prevented in the housing.

Die vertikale Geometrie der Vertiefung, insbesondere der Verlauf deren Bodenprofils relativ zur oberen Fläche der Gehäuseöffnung 4, ist an die Dicke des Schlüssels 5 angepasst. Vorzugsweise ist das Bodenprofil so ausgebildet, dass der Notschlüssel 5 nicht über die obere Fläche der Gehäuseöffnung 4 hinausragt, womit diese Fläche so ausgeführt werden kann, dass sie bei geschlossenem Gehäuse 1 an die Innenfläche der Gehäuseabdeckung 3 reicht. Dies ermöglicht eine großflächige Abstützung der Gehäuseabdeckung 3, die das geschlossene Gehäuse unempfindlich gegenüber mechanischen Einwirkungen macht. Im einfachsten Fall entspricht die vertikale Ausdehnung der Vertiefung 6 in etwa der Materialstärke des Notschlüssels 5. Aus weiter unten ausgeführten Gründen ist der Boden der Vertiefung 6 jedoch bevorzugt profiliert gestaltet, so dass der Notschlüsseln nur auf einer oder mehreren Teilflächen des Vertiefungsbodens zu liegen kommt.The vertical geometry of the recess, in particular the profile of its bottom profile relative to the upper surface of the housing opening 4, is adapted to the thickness of the key 5. Preferably, the bottom profile is formed so that the emergency key 5 does not over the upper surface of the housing opening 4 protrudes, so that this surface can be carried out so that it extends to the inner surface of the housing cover 3 with the housing 1 closed. This allows a large-area support of the housing cover 3, which makes the closed housing insensitive to mechanical effects. In the simplest case, the vertical extent of the recess 6 corresponds approximately to the material thickness of the emergency key 5. However, for reasons explained below, the bottom of the recess 6 is designed profiled, so that the emergency keys comes to rest only on one or more partial surfaces of the recess bottom.

Um ein einfaches Entnehmen des Notschlüssels 5 aus der Vertiefung 6 zu ermöglichen, weicht die Umrissgeometrie der Seitenwände der Vertiefung 6 an zumindest einer Stelle soweit von der lateralen Umrissgeometrie des Notschlüssels 5 ab, dass die Vertiefung wenigstens einen nicht vom Schlüssel eingenommenen muldenförmigen Bereich 7 ausbildet. Dieser Bereich 7 weist, um als Eingriff 7 zur Entnahme des Notschlüssels 5 dienen zu können, vorzugsweise keine Abgrenzung gegenüber dem für die Aufnahme des Schlüssels vorgesehenen Bereich auf. Die lateralen Abmessungen des Eingriffs sind dabei groß genug, um die Kuppe eines Fingers einzuführen. Damit der Notschlüssel 5 leicht aus der Vertiefung 6 entnommen werden kann, ist der Eingriff 7 vorzugsweise tiefer als der den Notschlüssel stützende Bereich des Vertiefungsbodens ausgeführt. Eine Entnahme des Schlüssels 5 aus der Vertiefung wird weiterhin dadurch erleichtert, dass sich der Bodenbereich des Eingriffs bis unter den Notschlüssel 5 erstreckt, womit dieser, beispielsweise mit einem Fingernagel, einfach untergriffen werden kann.In order to enable a simple removal of the emergency key 5 from the recess 6, the outline geometry of the side walls of the depression 6 deviates at least at one point from the lateral outline geometry of the emergency key 5 so that the recess forms at least one trough-shaped region 7 not occupied by the key. This area 7, in order to be able to serve as an engagement 7 for removing the emergency key 5, preferably has no delimitation with respect to the area provided for receiving the key. The lateral dimensions of the engagement are large enough to introduce the tip of a finger. Thus, the emergency key 5 can be easily removed from the recess 6, the engagement 7 is preferably carried out deeper than the emergency key supporting area of the well bottom. A removal of the key 5 from the recess is further facilitated by the fact that the bottom portion of the engagement extends below the emergency key 5, so that this, for example with a fingernail, can be easily under attack.

Der in der Figur 1 dargestellte Notschlüssel 5 weist einen Schlüsselbart 5a zum Betätigen eines Verschlussmechanismus des Zugangssystems und einen Schlüsselkopf 5b auf, mithilfe dessen ein Benutzer den Schlüssel betätigen kann. Im dargestellten Beispiel ist der Schlüsselkopf 5b als quer zur Längsachse des Schlüsselbarts angeordneter Quader ausgebildet, wodurch sich eine im Wesentlichen T-förmige Grundgestalt des Notschlüssels 5 ergibt. Diese Form ist nicht zwingend. Stattdessen kann der Schlüsselkopf beispielsweise auch eine runde Form aufweisen oder z.B. auch nur in einer einfachen Verlängerung des Schlüsselbarts 5a selbst bestehen. Die in der Figur 1 dargestellte Schlüsselform ermöglicht jedoch eine Übertragung größerer Drehmomente auf den Schlüsselbart 5a, ohne den Schlüssel 5 wesentlich über dessen Bartlänge hinaus zu verlängern.The Indian FIG. 1 shown emergency key 5 has a key bit 5a for actuating a locking mechanism of the access system and a key head 5b, by means of which a user can operate the key. In the example shown, the key head 5b is transverse to the Formed along the longitudinal axis of the key bit arranged cuboid, resulting in a substantially T-shaped basic shape of the emergency key 5. This form is not mandatory. Instead, the key head, for example, also have a round shape or, for example, consist only in a simple extension of the key bit 5a itself. The in the FIG. 1 However, shown key shape allows greater torque transmission to the key bit 5a, without extending the key 5 substantially beyond the beard length out.

Zur sicheren Verwahrung des Notschlüssels 5 im Inneren des Gehäuses 1 weist das Gehäuse 1 eine teilweise Überdeckung 8 der Vertiefung 6 und einen speziellen Verschlussmechanismus zur Verbindung der Gehäuseabdeckung 3 mit dem Grundgehäuse 2 auf.For safekeeping of the emergency key 5 in the interior of the housing 1, the housing 1 has a partial covering 8 of the recess 6 and a special locking mechanism for connecting the housing cover 3 to the base housing 2.

Die Überdeckung 8 überbrückt die Vertiefung 6 an einem Ende so, dass ein Endbereich des Schlüssels, vorzugsweise das freie Ende des Schlüsselbarts 5a oder ein Teil des Schlüsselkopfs 5b, beim Einlegen des Schlüssels in die Vertiefung 6 unterhalb der Überdeckung zu liegen kommt. Zum Entnehmen des Notschlüssels 5 muss dieser damit zuerst mit dem nicht überdeckten Teil aus der Vertiefung 6 heraus geschwenkt werden, bevor er schließlich unter der Überdeckung herausgezogen werden kann. Denn die oben beschriebene Anpassung der Umrissgeometrie der Vertiefung beschränkt die Bewegung eines in der Vertiefung 6 aufgenommen Schlüssels soweit, dass der in der Vertiefung 6 liegende Schlüssel nicht unter der Überdeckung herausgezogen werden kann.The cover 8 bridges the recess 6 at one end so that an end portion of the key, preferably the free end of the key bit 5a or a part of the key head 5b, comes to lie below the cover when inserting the key in the recess 6. In order to remove the emergency key 5, it must first be pivoted out of the recess 6 with the part not covered, before it can finally be pulled out under the cover. Because the above-described adaptation of the outline geometry of the recess limits the movement of a key received in the recess 6 so far that the key lying in the recess 6 can not be pulled out under the cover.

Voraussetzung für ein Entnehmen oder Herausfallen des Schlüssels ist daher, dass oberhalb des nicht überdeckten Endes des Schlüssels genügend freier Raum zum Herausschwenken des Notschlüssels vorhanden ist. Dazu muss die Gehäuseabdeckung 3, wie in Figur 1 gezeigt ist, entweder vollständig vom Grundgehäuse 2 entfernt sein, oder einen genügend großen Winkel dazu einnehmen, dass ein Schwenken des Notschlüssels 5 aus der Vertiefung 6 nicht behindert wird.
Um daher ein unbeabsichtigtes Herausschwenken des Notschlüssels 5 aus der Vertiefung 6 zu unterbinden, muss sichergestellt sein, dass bei einem unabsichtlichen Öffnen des Gehäuses 1 kein Raum oberhalb der überdeckungsfreien Zone der Vertiefung 6, das ist in dem Beispiel der Figur 1 der Bereich zur Aufnahme des Schlüsselkopfs, freigegeben wird. Hierzu ist ein Verschlussmechanismus vorgesehen, der die Gehäuseabdeckung 3 beim Öffnen zunächst nur im Bereich der Überdeckung 8 freigibt, so dass es einer weiteren Betätigung bedarf, um die Abdeckung 3 auch im nicht überdeckten Endbereich der Vertiefung zu Öffnen.
Dies wird erreicht, indem die Gehäuseabdeckung 3 im Bereich des nicht überdeckten Endes des Notschlüssels 5 gelenkig mit dem Grundgehäuse 2 verbunden ist. Die gelenkige Verbindung definiert dabei eine Schwenkachse, die in etwa im rechten Winkel zur Längsachse der Vertiefung 6 angeordnet ist. Die Längsachse der Vertiefung 6 ist durch die Linie gegeben, die die Bartspitze mit dem Schlüsselkopf eines in die Vertiefung eingesetzten Notschlüssels 5 verbindet. Die Ausführung der gelenkigen Verbindung erzwingt ein Schwenken der Abdeckung 3 um die Schwenkachse, wodurch ein Abheben der Abdeckung von dem nicht überdeckten Endbereich der Vertiefung verhindert wird. Durch Begrenzen des Schwenkwinkels kann zusätzlich verhindert werden, dass die als Innenfläche bzw. -seite bezeichnete Oberfläche der Abdeckung, d.h. die Seite, die bei geschlossenem Gehäuse 1 in dessen Inneren angeordnet ist, immer nahe genug an den überdeckungsfreien Endbereich der Vertiefung 6 heranreicht, um ein Herausschwenken des Notschlüssels 5 aus dieser Vertiefung unmöglich zu machen. Erfindungsgemäß wird die gelenkige Verbindung hierzu, wie in den Figuren veranschaulicht ist, als hakenförmig ausgebildeter, lösbarer Formschluss ausgeführt. Die Verbindung umfasst einen oder mehrere hakenförmige Fortsätze 9, die an der Innenseite der Gehäuseabdeckung 3 angeordnet sind und entsprechend ein oder mehrere Öffnungen 10 in einer Oberfläche des Grundgehäuses 2, durch das die hakenförmigen Fortsätze geführt werden können. Die im Folgenden als Haken 9 bezeichneten hakenförmigen Fortsätze 9 sind dabei so geformt, dass sie die Gehäusewand an der Öffnungskante untergreifen können und eine kleinwinkelige Schwenkbewegung um die untergriffene Öffnungskante ermöglichen. Ein Beispiel einer entsprechenden Verbindung ist in der Schnittdarstellung der Figur 2 vorgestellt. Der maximale Schwenkwinkel der Verbindung ist dabei gerade so groß gewählt, dass sich der unten zu beschreibende Verriegelungsmechanismus für das Schließen der Abdeckung 3 gerade entriegeln lässt. Das Schwenken der Gehäuseabdeckung kann dabei mit einer leichten lateralen Verschiebung einhergehen, sodass die Schwenkachse beim Öffnen des Gehäuses ihre Lage verändert. Die in den Figuren dargestellte Ausführungsform stellt nur ein Beispiel möglicher mit Haken realisierter gelenkiger Verbindungen dar. Anzahl, Lage und Form der Haken können auch anders ausgeführt werden. Beispielsweise kann nur ein Haken 9 z.B. an der Endkante der Abdeckung im Kopfbereich des Notschlüssels vorgesehen sein, wobei die Begrenzung des Schwenkwinkels mittels der Hakenform unter Umständen auch in Verbindung mit inneren Oberflächen des Grundgehäuses 2 unterhalb der Öffnung 10 bewirkt werden kann.Prerequisite for a removal or falling out of the key is therefore that above the uncovered end of the key enough free space for swinging out of the emergency key is present. For this purpose, the housing cover 3, as in FIG. 1 is shown, either completely removed from the base housing 2, or a sufficiently large angle thereto assume that pivoting the emergency key 5 from the recess 6 is not hindered.
Therefore, in order to prevent unintentional swinging out of the emergency key 5 from the recess 6, it must be ensured that in an unintentional opening of the housing 1 no space above the coverage-free zone of the recess 6, which is in the example of FIG. 1 the area for receiving the key head is released. For this purpose, a closure mechanism is provided which initially releases the housing cover 3 only in the region of the cover 8 during opening, so that further actuation is required in order to open the cover 3 in the uncovered end region of the recess.
This is achieved by the housing cover 3 in the region of the uncovered end of the emergency key 5 is pivotally connected to the base housing 2. The articulated connection defines a pivot axis, which is arranged approximately at right angles to the longitudinal axis of the recess 6. The longitudinal axis of the recess 6 is given by the line connecting the tip of the beard with the key head of an emergency key 5 inserted into the recess. The execution of the hinged connection forces pivoting of the cover 3 about the pivot axis, whereby a lifting of the cover from the uncovered end portion of the recess is prevented. By limiting the pivoting angle can be additionally prevented that designated as the inner surface or side surface of the cover, ie the side, which is arranged with the housing closed 1 in the interior, always close enough to the non-overlapping end portion of the recess 6 to to make it impossible to swing out the emergency key 5 from this depression. According to the invention, the articulated connection for this purpose, as illustrated in the figures, as a hook-shaped, releasable positive connection executed. The connection comprises one or more hook-shaped projections 9, which are arranged on the inside of the housing cover 3 and corresponding to one or more openings 10 in a surface of the base housing 2, through which the hook-shaped extensions can be guided. The hereinafter referred to as hooks 9 hook-shaped extensions 9 are shaped so that they can engage under the housing wall at the opening edge and allow a small-angle pivotal movement about the undercut opening edge. An example of a corresponding connection is in the sectional view of FIG. 2 presented. The maximum pivot angle of the connection is just chosen so large that can be unlocked just below to be described locking mechanism for closing the cover 3. The pivoting of the housing cover can be accompanied by a slight lateral displacement, so that the pivot axis changes its position when the housing is opened. The embodiment shown in the figures represents only an example of possible hook-realized hinged connections. The number, position and shape of the hooks can also be designed differently. For example, only one hook 9 may be provided, for example, at the end edge of the cover in the head region of the emergency key, wherein the limitation of the pivot angle by means of the hook shape may possibly be effected in conjunction with inner surfaces of the base housing 2 below the opening 10.

Neben der gelenkigen Verbindung umfasst der Verschlussmechanismus des Gehäuses 1 weiterhin einen Verriegelungsmechanismus, der in einem Abstand zur gelenkigen Verbindung angeordnet ist. Als Riegel 11 sind in der Innenfläche der Abdeckung 3 ein oder mehrere hakenförmige Fortsätze angebracht, deren Materialelastizität eine begrenzte Bewegung ihrer freien Enden zulassen.In addition to the articulated connection, the locking mechanism of the housing 1 further comprises a locking mechanism, which is arranged at a distance from the articulated connection. As a bolt 11, one or more hook-shaped projections are attached in the inner surface of the cover 3, the material elasticity allow limited movement of their free ends.

Die Abbildung der Figur 3 zeigt einen Querschnitt durch das geschlossene Gehäuse 1 im Bereich des Verriegelungsmechanismus. Die Gehäuseabdeckung 3 weist in der dargestellten Ausführungsform zwei vom Querschnitt erfasste Riegel 1 auf, die spiegelsymmetrisch zur Längsachse der Vertiefung 6 angeordnet sind. Die Abdeckung 3 sitzt in einer Ausnehmung der Oberschale 2a des Grundgehäuses 2. An den freien Enden sind die Riegel 11 dicker als an den an die Innenseite der Gehäuseabdeckung 3 anschließenden Abschnitten ausgeführt. Diese Verdickungen bilden die Kopfenden der Riegel 11. Lage und Gestaltung der Riegel 11 ermöglichen es, dass die Gehäuseabdeckung die untere Innenkante der Oberschale 2a wie in der Figur 3 gezeigt mit den Kopfenden der Riegel 11 untergreift und dadurch mit einem Teil ihrer Innenfläche gegen korrespondierende Oberflächen der in der Oberschale 2a ausgebildeten Gehäuseöffnung 4 gedrückt wird.The picture of the FIG. 3 shows a cross section through the closed housing 1 in the region of the locking mechanism. In the illustrated embodiment, the housing cover 3 has two bars 1, which are detected by the cross section and are arranged mirror-symmetrically with respect to the longitudinal axis of the recess 6. The cover 3 is seated in a recess of the upper shell 2a of the base housing 2. At the free ends of the bolt 11 are thicker than at the adjoining the inside of the housing cover 3 sections. These thickenings form the head ends of the latch 11. Location and design of the latch 11 allow the housing cover the lower inner edge of the upper shell 2a as in the FIG. 3 shown engages with the head ends of the latch 11 and is thereby pressed with a part of its inner surface against corresponding surfaces of the formed in the upper shell 2a housing opening 4.

Zum Öffnen dieser Verriegelung ist ein bzw. sind mehrere an der Unterseite der Oberschale 2a verschiebbare Öffnungselemente 12 vorgesehen, das bzw. die gegen die Kopfenden des oder der Riegel gedrückt werden können, um diese aus dem Bereich unterhalb der unteren Innenkante der Oberschale 2a herauszudrücken und die Abdeckung 3 damit freizugeben. Vorzugsweise sind die Berührungsflächen zwischen Riegelkopfende und Öffnungselement 12 wie in Figur 3 gezeigt in einander entsprechender Weise gegenüber der Verschieberichtung des Öffnungselements geneigt angeordnet, so dass die Gehäuseabdeckung nach ihrer Entriegelung mittels der Öffnungselemente 12 aus der Oberschale 2a gehoben wird.To open this lock one or more on the underside of the upper shell 2a slidable opening elements 12 are provided, which or can be pressed against the head ends of the bolt or to push them out of the area below the lower inner edge of the upper shell 2a and to release the cover 3 with it. Preferably, the contact surfaces between latch head end and opening element 12 are as in FIG FIG. 3 shown in a corresponding manner with respect to the direction of displacement of the opening element inclined, so that the housing cover is lifted after its release by means of the opening elements 12 of the upper shell 2a.

Vorzugsweise sind die Öffnungselemente 12 an der zum Gehäuseinneren gewandten Seite von Griffelementen 13 angebracht, die von einem oder mehreren Federelementen 14 in einer Ruhelage gehalten werden, die keine Öffnung der Gehäuseabdeckung bewirkt. Ein Beispiel für eine entsprechende Konstruktion ist in der Detaildarstellung von Figur 4 vorgestellt. Die Darstellung zeigt den Verriegelungsmechanismus aus der Richtung der hier nicht dargestellten Unterschale 2b des Grundgehäuses 2. Die beiden Öffnungselemente 12 können einstückig mit den Griffelementen und dem U-förmig ausgebildeten Federelement 14 ausgeführt sein und somit einen Aufbau des Öffnungsmechanismus ermöglichen, der z.B. kostengünstig aus einem Kunststoffmaterial gefertigt sein kann. Der Öffnungsmechanismus kann wie aus der Abbildung von Figur 4 ersichtlich weitere Konstruktionsmerkmale für weitere Funktionen des Gehäuses aufweisen, beispielsweise eine Schlüsselringaufnahme, eine Öse oder Ähnliches.Preferably, the opening elements 12 are attached to the interior of the housing facing side of handle members 13 which are held by one or more spring elements 14 in a rest position, which causes no opening of the housing cover. An example of a corresponding construction is in the detail of FIG. 4 presented. The illustration shows the locking mechanism from the direction of the lower shell 2b of the base housing 2, not shown here. The two opening elements 12 may be integral with be designed to handle elements and the U-shaped spring element 14 and thus allow a structure of the opening mechanism, which may be inexpensively made of a plastic material, for example. The opening mechanism may be as shown in the picture FIG. 4 may have further design features for other functions of the housing, such as a key ring receptacle, an eyelet or the like.

Um einen in der Vertiefung 6 verwahrten Notschlüssel 5 aus dem geschlossenen Gehäuses 1 zu entnehmen, drückt ein Benutzer zum Entriegeln des oben beschriebenen Verriegelungsmechanismus auf die beiden Griffelemente 13 wodurch die Gehäuseabdeckung 3 im Bereich der Verriegelung etwas vom Grundgehäuse weggedrückt und dadurch um einen kleinen Winkel um die Schwenkachse der gelenkigen Verbindung geschwenkt wird. Da die Gehäuseabdeckung 3 nun etwas zum Grundgehäuse beabstandet ist, kann der Benutzer sie im Bereich der Verriegelung ergreifen und soweit verschieben, dass die Schwenkhaken 9 aus den Öffnungen 10 geführt und die Gehäuseabdeckung abgehoben werden kann.In order to remove a stored in the recess 6 emergency key 5 from the closed housing 1, a user presses for unlocking the locking mechanism described above on the two handle members 13 whereby the housing cover 3 in the region of the locking pushed away from the base housing and thereby at a small angle the pivot axis of the articulated connection is pivoted. Since the housing cover 3 is now slightly spaced from the base housing, the user can take them in the region of the lock and move so far that the pivot hooks 9 out of the openings 10 and the housing cover can be lifted.

Zum Drehen des Notschlüssels 5 kann der Benutzer diesen am Kopfende anfassen. Die Abmessungen des Kopfendes sind im Allgemeinen klein gehalten, damit das Gehäuse nicht unnötig groß ausgeführt werden muss. Dadurch kann der Benutzer jedoch nur ein kleines Drehmoment auf den Schlüssel ausüben, das z.B. bei vereisten Türschlössern nicht mehr ausreichend sein kann, um den Schließmechanismus zu betätigen. Die Vertiefung 6 ist daher im Bereich zur Aufnahme des Schlüsselkopfs 5b so ausgestaltet, dass der Notschlüssel in der in der Figur 5 dargestellten Weise in einem mehr oder weniger rechten Winkel zu seiner Verwahrungsstellung in die Vertiefung gesteckt werden kann. Auf diese Weise übernimmt das Gehäuse 1 die Funktion eines erweiterten Schlüsselkopfs der eine Schließbetätigung mit einem wesentlich höheren Drehmoment ermöglicht.To rotate the emergency key 5, the user can touch it at the head end. The dimensions of the head end are generally kept small so that the housing does not need to be unnecessarily large. As a result, the user can exercise only a small torque on the key, which may not be sufficient, for example, in icy door locks to operate the locking mechanism. The recess 6 is therefore designed in the area for receiving the key head 5b so that the emergency key in the in the FIG. 5 illustrated manner can be inserted in a more or less right angle to its storage position in the recess. In this way, the housing 1 assumes the function of an extended key head which allows a closing operation with a much higher torque.
