Abstract

To increase the value of a key, especially of a flat key, for example a car key, the head of the key is produced from a precious metal and is connected releaseably to the shank 1 of the key. A snap fastening serves for connecting the shank 1 to the head 2 and is brought about by studs 8 insertable into holes in the head 2 and shank 1 and by a clamping plate 6 inserted into the head 2. The technical effect of the assembleable key is that, when the vehicle is changed, the head can be exchanged for a key of another type of vehicle or of another lock. There is also the possibility that the precious metal can be used for other processing work. <IMAGE>

Description

Die Erfindung betritt einen Flachschlüssel nach dem Oberbegriff des Patentanspruches 1.The invention enters a flat key according to the preamble of claim 1.

Flachschlüssel dieser Art sind durch die CA-A-1 107 529 bekanntgeworden. Bei diesem Flachschlüssel besteht der Kopf aus einem ausgesparten Boden mit einem die Aussparung desselben abschließenden Deckel, wobei der Schlüssel in der Aussparung festgehalten ist. Durch die zweiteilige Ausbildung des Kopfes ergibt sich eine verhältnismäßig umständliche Herstellungsweise sowie Montage des Schlüssels.Flat keys of this type have become known from CA-A-1 107 529. In this flat key, the head consists of a recessed bottom with a cover closing the recess, the key being held in the recess. The two-part design of the head results in a relatively cumbersome production method and assembly of the key.

Aufgabe der Erfindung ist die Schaffung von Maßnahmen, durch welche dieser Nachteil beseitigt wird und außerdem die Möglichkeit geboten ist, den Schlüsselkopf aus Edelmetall und den Schlüsselschaft aus den üblichen Materialien herzustellen, da Schlüssel dieserArt häufig als Autoschlüssel verwendet werden, bei welchen der Benützer oft den Wunsch hat, den Schlüssel zu veredeln.The object of the invention is to provide measures which overcome this disadvantage and also offer the possibility of producing the key head from precious metal and the key shaft from the usual materials, since keys of this type are often used as car keys, in which the user often uses the key Desires to refine the key.

Diese Aufgabe wird bei einem Schlüssel der eingangs erwähnten Art durch die Maßnahme nach dem kennzeichnenden Teil des Patentanspruches 1 gelöst.This object is achieved with a key of the type mentioned by the measure according to the characterizing part of claim 1.

Dadurch besteht die Möglichkeit, zum Beispiel beim Kaufeines neuen Autos den Kopf nach Entfernen des Schaftes mit einem anderen Schaft zu verbinden oder für den Fall, daß der Schlüssel nicht mehr gebraucht wird, als Rohstoff für andere Zwecke zu verwenden, z.B. zur Herstellung von Schmuckstücken.This makes it possible to connect the head to another shaft after removing the shaft, for example when buying a new car, or to use it as a raw material for other purposes in the event that the key is no longer used, e.g. for the production of jewelry.

Weitere Vorteile der Erfindung ergeben sich aus den Merkmalen der Unteransprüche.Further advantages of the invention result from the features of the subclaims.

  • 1 is a composite flat key in plan view,
  • 2 shows the head in plan view with the fixing device for the assembled key removed,

Der erfindungsgemäße Schlüssel besteht in der dargestellten Form aus einem flachen Schaft 1 und einem im wesentlichen flachen Kopf 2, welcher mit dem Schaft 1 lösbar verbunden ist. Zu diesem Zwecke sind Kopf und Schaft mit je zwei nebeneinanderliegenden korrespondierenden Löchern 3, 4 versehen, welche beim Einsetzen des Schaftes 1 in einen Schlitz 5 des Kopfes 2 fluchten. Der Schlitz 5 ist so hoch, daß in diesen der Schaft 1 und darüber eine Klemmplatte 6 streng eingeschoben werden können.In the form shown, the key according to the invention consists of a flat shaft 1 and an essentially flat head 2, which is detachably connected to the shaft 1. For this purpose, the head and shaft are each provided with two adjacent holes 3, 4, which are aligned when the shaft 1 is inserted into a slot 5 of the head 2. The slot 5 is so high that the shaft 1 and above it a clamping plate 6 can be inserted strictly.

Zur Sicherung des eingeschobenen Schaftes 1 im Schlitz 5 gegen Herausziehen ist ein Plättchen 7 vorgesehen, welches mit zwei Stiften 8 versehen ist, die in die fluchtenden Löcher 3,4einsetzbar sind. Um ein ungewolltes Herausziehen des Plättchens 7 aus dem Kopf 2 zu verhindern, ist eine Klemmplatte 6 vorgesehen, welche für jeden der Stifte ein federndes Zinkenpaar aufweist, deren Zinken 9 federnd sind und einen Schnappverschluß bilden, indem sie innenseitig je eine Kerbe 10 aufweisen, welche in korrespondierende Kerben 11, Umlaufnuten od. dgl. der Stifte 8, nach dem Einsetzen in der Klemmplatte 6 in den Schlitz 5, einrasten. Die Kerben 10 liegen in einer Linie. Die Kerben 11, Umlaufnuten od.dgl. befinden sich vorzugsweise an der Wurzel der Stifte 8 und haben eine Höhe, welche etwa der Dicke der mit den Löchern 3 versehenen Schlitzwand zuzüglich der Dicke der Klemmplatte 6 entspricht. Zum Einsetzen des Werkzeuges ist die Klemmplatte 6 an einem aus dem Schlitz 5 geringfügig herausragenden Ende mit einem Loch 13 versehen. Dadurch ist es möglich, die Dicke der Klemmplatte 6 so zu wählen, daß die Klemmplatte 6 mit dem Schaft 1 im Schlitz 5 so festsitzt, daß ein Herausfallen der Klemmplatte 6 oder ein leichtes Herausziehen derselben verhindert wird.To secure the inserted shaft 1 in the slot 5 against being pulled out, a plate 7 is provided, which is provided with two pins 8 which can be inserted into the aligned holes 3, 4. In order to prevent unwanted pulling of the plate 7 out of the head 2, a clamping plate 6 is provided, which has a resilient pair of prongs for each of the pins, the prongs 9 of which are resilient and form a snap closure by having a notch 10 on the inside, which Snap into corresponding notches 11, circumferential grooves or the like of the pins 8 after insertion in the clamping plate 6 in the slot 5. The notches 10 lie in a line. The notches 11, grooves or the like. are preferably located at the root of the pins 8 and have a height which corresponds approximately to the thickness of the slot wall provided with the holes 3 plus the thickness of the clamping plate 6. To insert the tool, the clamping plate 6 is provided with a hole 13 at an end slightly protruding from the slot 5. This makes it possible to choose the thickness of the clamping plate 6 so that the clamping plate 6 with the shaft 1 is stuck in the slot 5 in such a way that the clamping plate 6 does not fall out or is easily pulled out.

Das Lösen des Schaftes 1 vom Kopf 2 erfolgt mit einem entsprechenden Werkzeug, mit dem die Klemmplatte 6 gegen die Federkraft der Zinken 9 mit den Stiften 8 aus dem Schlitz 5, herausgezogen wird. zu diesem Zwecke ist am Ende der Klemmplatte 6 ein Loch 13 vorgesehen, welches im zusammengebauten Zustand des Schlüssels, wie Fig. 1 zeigt, aus dem Kopf 2 herausragt und zum Einsetzen des Werkzeuges dient.The shaft 1 is released from the head 2 using a corresponding tool, with which the clamping plate 6 is pulled out of the slot 5 against the spring force of the prongs 9 with the pins 8. For this purpose, a hole 13 is provided at the end of the clamping plate 6, which in the assembled state of the key, as shown in FIG. 1, protrudes from the head 2 and is used for inserting the tool.

Die erfindungsgemäße Konstruktion des Schlüssels dient modischen und Eitelkeitszwecken, bietet aber auch die Möglichkeit, beim Umsteigen auf ein anderes Fahrzeug, den wertvollen Kopf 2 auf einen anderen Schaft 1 aufzustecken. Das Plättchen 7 kann auf der Oberseite mit dem Fahrzeugzeichen versehen sein. Weiteres bietet die erfindungsgemäße Konstruktion die Möglichkeit, den Kopf 2, der aus Gold, Silber oder Platin hergestellt ist, für andere Zwecke zu verwenden, beispielsweise zu einem Schmuckstück zu verarbeiten.The construction of the key according to the invention serves fashion and vanity purposes, but also offers the possibility of attaching the valuable head 2 to another shaft 1 when changing to another vehicle. The plate 7 can be provided with the vehicle sign on the top. Furthermore, the construction according to the invention offers the possibility of using the head 2, which is made of gold, silver or platinum, for other purposes, for example to process it into a piece of jewelry.

Selbstverständlich können im Rahmen der Erfindung verschiedene konstruktive Änderungen vorgenommen werden. So kann der lösbare Verschluß zwischen Schaft 1 und Kopf 2 anders als beschrieben gelöst werden.Of course, various design changes can be made within the scope of the invention. So the releasable closure between shaft 1 and head 2 can be released differently than described.

So kann die Anzahl der Löcher 3, 4, die Klemmplatte 6 und auch das Verschlußplättchen 7 in anderer Form ausgeführt sein. Die Form des Kopfes 2 ist ebenfalls dem Designer überlassen. in allen Fällen besitzt er vorzugsweise eine Öffnung 12 zum Auffädeln des Schlüssels auf einen Schlüsselring.Thus, the number of holes 3, 4, the clamping plate 6 and also the closure plate 7 can be designed in a different form. The shape of the head 2 is also left to the designer. in all cases it preferably has an opening 12 for threading the key onto a key ring.
