Description

Die Erfindung betrifft einen Flachschlüssel mit einem Griffteil und einem Schlüsselbart, wobei das Griffteil ein Gehäuse umfaßt und der Schlüsselbart in das Griffteilgehäuse hinein- sowie aus diesem herausbewegbar angeordnet und in seiner jeweiligen Endlage fixierbar ist.The invention relates to a flat key with a handle part and a key bit, wherein the handle part comprises a housing and the key bit into the handle part housing arranged in and out of this and arranged in its respective end position is fixable.

Derartige Flachschlüssel weisen den Vorteil auf, daß sie relativ wenig Platz einnehmen und daß bei ihrem Tragen, z.B. in einer Mantel- oder Hosentasche, eine geringere Verletzungsgefahr besteht als bei Flachschlüsseln mit starr an dem Griffteil befestigten Schlüsselbart.Such flat keys have the advantage that they take up relatively little space and that when worn, e.g. in a coat or trouser pocket, less risk of injury exists as with flat keys with rigidly attached to the handle Key beard.

Üblicherweise wird bei den bekannten gattungsgemäßen Flachschlüsseln der Schlüsselbart über eine Drehfeder aus dem Griffteilgehäuse herausgeklappt bzw. gegen den Druck der Drehfeder in das Griffteilgehäuse hineingeschwenkt. Die Sicherung des Gehäusebartes in der jeweiligen Endlage erfolgt dabei mittels eines an dem Griffteil angeordneten Druckknopfes.Usually the key bit is used in the known generic flat keys folded out of the grip part housing via a torsion spring or against the Pressure of the torsion spring swung into the handle housing. Securing the beard in the respective end position takes place by means of a arranged on the handle part Push button.

Nachteilig ist bei diesen bekannten Flachschlüsseln unter anderem, daß zum Einklappen des Schlüsselbartes in der Regel zwei Hände verwendet werden müssen. Außerdem benötigt der Schlüsselbart zum Ein- und Ausschwenken einen relativ großen Schwenkradius, so daß es häufig zu Problemen kommen kann, wenn der Schlüsselbart durch versehentliches Betätigen des Druckknopfes in der Mantel- oder Hosentasche etc. herausgeschwenkt wird. Ferner kann es beim Einschwenken des Schlüsselbartes leicht zu einem Einklemmen von Fingern kommen. One disadvantage of these known flat keys is that they can be folded in the mustache must usually be used with two hands. Moreover the key bit needs a relatively large one to pivot in and out Swivel radius, so that problems can often arise if the key bit by accidentally pressing the push button in the coat or trouser pocket etc. is swung out. It can also be easy when swinging the key bit fingers pinching.

Aus der nicht vorveröffentlichten deutschen Patentanmeldung 199 12 749.2 ist bereits ein Flachschlüssel bekannt, bei dem der Schlüsselbart in dem Griffteilgehäuse axial verschiebbar gelagert ist. Dabei erfolgt die Verschiebung des Schlüsselbartes einerseits mit Hilfe eines an einem Kopfteil des Schlüsselbartes angeordneten Zahnrades, welches in eine sich in Richtung der Längsachse des Schlüssels erstreckende gehäusefeste Verzahnung eingreift, und andererseits mit Hilfe einer Feder, die den Schlüsselbart in seine herausgeschobene Endlage drückt und die durch das Hineinschieben des Schlüsselbartes in das Griffteilgehäuse vorgespannt wird.From the unpublished German patent application 199 12 749.2 is already a flat key is known in which the key bit in the handle housing axially is slidably mounted. The key bit is shifted on the one hand with the help of a gear arranged on a head part of the key bit, which in a housing-fixed toothing extending in the direction of the longitudinal axis of the key engages, and on the other hand with the help of a spring that the key bit in his pushed out end position and by pushing the key bit is biased into the handle housing.

Nachteilig ist bei diesem Flachschlüssel vor allem, daß der aus Zahnrad, Verzahnung und Feder bestehende Antrieb relativ kosten- und platzaufwendig ist.A disadvantage of this flat key is that the gear, toothing and spring existing drive is relatively expensive and space-consuming.

Der Erfindung liegt die Aufgabe zugrunde, einen Flachschlüssel mit einem axial verschiebbaren Schlüsselbart anzugeben, der einen kostengünstig herstellbaren Antrieb besitzt und einen relativ geringen Bauraum benötigt.The invention has for its object a flat key with an axially displaceable Key bit to specify a drive that can be manufactured cost-effectively has and requires a relatively small amount of space.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is achieved by the features of claim 1. Further, particularly advantageous configurations of the invention are disclosed in the subclaims.

Die Erfindung beruht im wesentlichen auf dem Gedanken, als Antrieb in dem Griffteilgehäuse eine Feder anzuordnen, deren beide Endbereiche jeweils spiralförmig auf zwei seitlich von dem Schlüsselbart angeordnete Aufnahmen (Federkerne) gewickelt sind. Der mittlere Bereich der Feder stützt sich an einer Abstützung des innerhalb des Griffteilgehäuses befindlichen Endes des Schlüsselbartes ab, so daß beim Einschieben des Schlüsselbartes in das Griffteilgehäuse die Feder von den Federkernen abgewickelt und damit gespannt wird.The invention is essentially based on the idea of a drive in the handle part housing to arrange a spring, the two end portions of each spiral on two Recordings (spring cores) arranged on the side of the key bit are wound. The central area of the spring is supported on a support within the handle part housing located end of the key bit, so that when inserting the Key bit in the handle part housing the spring unwound from the spring cores and to be excited.

Bei der Feder kann es sich um eine Spiralfeder handeln, deren Enden jeweils mit den Federkernen verbunden sind. Als vorteilhafter hat es sich in der Praxis allerdings erwiesen, statt üblicher Spiralfedern Rollfedern zu verwenden, bei denen die Enden nicht eingespannt sind (d.h. nicht mit dem Federkern fest verbunden sind). Mit derartigen Federn lassen sich relativ flache Federkraftkennlinien realisieren, so daß auch bei einem langen Verschiebeweg des Schlüsselbartes auf diesen eine gleichmäßige Kraft wirkt.The spring can be a spiral spring, the ends of which coincide with the Innersprings are connected. In practice, however, it has proven to be more advantageous instead of conventional coil springs, use coil springs where the ends are not are clamped (i.e. not firmly connected to the spring core). With such Springs can be realized relatively flat spring force characteristics, so that even one long displacement of the key bit has an even force on it.

Als vorteilhaft hat es sich ferner erwiesen, wenn die Federkerne als Rollen ausgebildet sind, an denen sich der Schlüsselbart seitlich abstützt und somit bei seiner Bewegung in das Griffteilgehäuse hinein- bzw. aus dem Griffteilgehäuse herausgeführt wird, da bei einer derartigen Ausgestaltung des Flachschlüssels nur geringe Reibungskräfte zwischen dem Schlüsselbart und dem Griffteilgehäuse auftreten. Dabei sollten die Rollen mindestens in den Bereichen, in denen sich der Schlüsselbart an ihnen abstützt, aus Gummi oder Kunststoff bestehen.It has also proven to be advantageous if the spring cores are designed as rollers are on which the key bit is supported laterally and thus when moving in the handle part housing is led in or out of the handle part housing, since at such a configuration of the flat key only low friction forces between the key bit and the handle housing. The roles should be at least in the areas where the key bit is supported on them Made of rubber or plastic.

Bei einer Ausführungsform der Erfindung besteht die Abstützung des Schlüsselbartes aus einem zapfenförmigen Teil, um den der mittlere Bereich der Rollfeder außenseitig herumgeführt ist. Dabei greift das zapfenförmige Teil mit seinem dem Schlüsselbart abgewandten Ende in eine sich in Richtung der Längsachse des Schlüssels erstreckende nutenförmige Ausnehmung formschlüssig ein, so daß der Schlüsselbart bei seiner Verschiebung entsprechend axial geführt wird.In one embodiment of the invention, the key bit is supported from a peg-shaped part around which the central area of the roller spring is on the outside is led around. The pin-shaped part engages with its key bit opposite end in an extending in the direction of the longitudinal axis of the key groove-shaped recess with a positive fit, so that the key bit when it is moved is guided axially accordingly.

Zur Sicherung des Schlüsselbartes in seinen beiden Endlagen weist das zapfenförmige Teil eine Ausnehmung auf, in der ein verschiebbar angeordneter federbelasteter Stift gelagert ist, der in den beiden Endlagen des Schlüsselbartes formschlüssig in eine entsprechende Ausnehmung des Griffteilgehäuses eingreift. Zur Lösung der Fixierung des Schlüsselbartes ist mindestens ein von außen drückbares Betätigungselement an dem Griffteil angeordnet, welches auf den Stift einwirkt, derart, daß bei Druck auf das Betätigungselement der Stift aus der jeweiligen Ausnehmung des Griffteilgehäuses heraus- und in die Ausnehmung des zapfenförmigen Teiles hineingedrückt wird und der Schlüsselbart somit anschließend axial verschoben werden kann.To secure the key bit in its two end positions, the pin-shaped Part a recess in which a slidably arranged spring-loaded pin is stored, which in the two end positions of the key bit positively into a corresponding Recess of the grip part housing engages. To solve the fixation of the Key bit is at least one actuating element that can be pressed from the outside Handle part arranged, which acts on the pin, such that when pressed on the actuating element the pin out of the respective recess of the handle part housing and is pressed into the recess of the pin-shaped part and the key bit can then be moved axially.

Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus dem folgenden anhand von Figuren erläuterten Ausführungsbeispiel. Es zeigen:

  • Fig.1 den Längsschnitt eines erfindungsgemäßen Flachschlüssels, wobei der Schlüsselbart sich in seiner herausgeschobenen Endlage befindet;
  • Fig.2 und 3 zwei vergrößerte Querschnitte durch den in Fig.1 dargestellten Flachschlüssel entlang der dort mit II-II und III-III bezeichneten Schnittlinien;
  • Fig.4 den Längsschnitt der oberen Hälfte des gegenüber Fig. 1 um 90° gedrehten Flachschlüssels.
    • Further details and advantages of the invention result from the following exemplary embodiment explained with reference to figures. Show it:
  • 1 shows the longitudinal section of a flat key according to the invention, the key bit being in its pushed-out end position;
  • 2 and 3 show two enlarged cross sections through the flat key shown in FIG. 1 along the section lines designated there by II-II and III-III;
  • 4 shows the longitudinal section of the upper half of the flat key turned by 90 ° compared to FIG.

    • In Fig.1 ist mit 1 ein Flachschlüssel bezeichnet, der sich aus einem Griffteil 2 und einem Schlüsselbart 3 zusammensetzt. Das Griffteil 2 umfaßt ein Gehäuse 4, in welches der Schlüsselbart 3 einschiebbar ist und welches aus zwei miteinander verklipsten schalenförmigen Gehäusehälften 5, 6 (fig.2 und 3) aus Kunststoff besteht. In Figure 1, 1 denotes a flat key, which consists of a handle part 2 and a Key bit 3 is composed. The handle part 2 comprises a housing 4, in which the Key bit 3 can be inserted and which consists of two bowl-shaped clipped together Housing halves 5, 6 (fig. 2 and 3) are made of plastic.

    In dem Griffteilgehäuse 4 ist eine Rollfeder 7 angeordnet, deren Endbereiche 8, 9 jeweils spiralförmig um zwei seitlich von dem Schlüsselbart 3 angeordnete Rollen 10, 11 gewickelt sind und deren mittlerer Bereich 12 um ein zapfenförmiges Teil 13 eines mit dem Griffteilgehäuse 4 verbundenen Kopfteiles 14 aus Kunststoff herumgeführt ist. Der Schlüsselbart 3 stützt sich seitlich an den aus Kunststoff bestehenden Rollen 10, 11 ab.A roller spring 7 is arranged in the grip part housing 4, the end regions 8, 9 of which are each spirally around two rollers 10, 11 arranged laterally from the key bit 3 are wound and the central region 12 with a pin-shaped part 13 the handle part housing 4 connected head part 14 is made of plastic. The Key bit 3 is supported laterally on the plastic rollers 10, 11.

    Das Griffteilgehäuse 4 weist eine sich in Richtung der Längsachse 15 des Schlüssels 1 erstreckende nutenförmige Ausnehmung 16 auf (Fig.4), in welche das zapfenförmige Teil 13 hineinragt und bei der Verschiebung des Schlüsselbartes 3 formschlüssig geführt wird. Außerdem besitzt das zapfenförmige Teil 13 eine Ausnehmung 17, in der ein verschiebbar angeordneter federbelasteter Stift 18 gelagert ist, der in den beiden Endlagen des Schlüsselbartes formschlüssig in eine entsprechende Ausnehmung 19, 20 des Griffteilgehäuses 4 eingreift.The handle part housing 4 has one in the direction of the longitudinal axis 15 of the key 1 extending groove-shaped recess 16 on (Fig.4), in which the pin-shaped Part 13 protrudes and guided positively when the key bit 3 is moved becomes. In addition, the pin-shaped part 13 has a recess 17 in which a Slidably arranged spring-loaded pin 18 is mounted, which is in the two end positions the key bit positively into a corresponding recess 19, 20 of the Handle part housing 4 engages.

    Der Flachschlüssel 1 umfaßt ein außenseitig an dem Griffteilgehäuse 4 angeordnetes wippenförmiges Betätigungselement 21, welches in seinen beiden Endbereichen gegen den Stift 18 gerichtete Vorsprünge 22, 23 aufweist, die bei entsprechendem Druck derart auf den Stift 18 einwirken, daß dieser aus der jeweiligen Ausnehmung 19, 20 des Griffteilgehäuses 4 heraus- und in die Ausnehmung 17 des zapfenförmigen Teiles 13 hineindrückbar ist, so daß der Schlüsselbart 3 entweder durch äußeren Druck in das Griffteilgehäuse 4 hinein- oder durch den Druck der vorgespannten Rollfeder 7 aus dem Gehäuse 4 herausgedrückt wird.The flat key 1 comprises an externally arranged on the handle part housing 4 rocker-shaped actuating element 21, which in its two end regions against the pin 18 has directed projections 22, 23 which, with appropriate pressure, such act on the pin 18 so that it from the respective recess 19, 20 of the Grip part housing 4 out and into the recess 17 of the pin-shaped part 13th is pushable, so that the key bit 3 either by external pressure in the Handle part housing 4 in or by the pressure of the preloaded roller spring 7 from the Housing 4 is pushed out.

    Wie den Fig.3 und 4 unmittelbar zu entnehmen ist, sind der Schlüsselbart 3, die Feder 7, die Rollen 10, 11 und das Betätigungselement 21 in nur einer Gehäusehälfte 6 befestigt, so daß alle wesentlichen Teile des Schlüssels 1 auf einfache Weise in dieser Gehäusehälfte vormontiert werden können. Die jeweils andere Gehäusehälfte 5 dient lediglich als Deckel zum Verschließen des Griffteilgehäuses 4.3 and 4 can be seen directly, the key bit 3, the spring 7, the rollers 10, 11 and the actuating element 21 are fastened in only one housing half 6, so that all essential parts of the key 1 in a simple manner in this housing half can be pre-assembled. The other housing half 5 only serves as a cover for closing the handle part housing 4.

    Der zwischen den Gehäusehälften 5 und 6 gebildete Hohlraum 24 ist derart gewählt, daß in ihm bei einem elektronischen Schließsystem die in dem Schlüssel anzuordnenden elektronischen Komponenten untergebracht werden können. The cavity 24 formed between the housing halves 5 and 6 is selected in such a way that in it with an electronic locking system those to be arranged in the key electronic components can be accommodated.
