Definitions
- the invention relates to a key, in particular a flat key for a lock cylinder, with key shank and key grain and also a knob on a lock cylinder, which is provided according to a key to lock the lock cylinder.
- a key in a lock cylinder In order to fully insert a latch in a mortise lock in the stock-side striker, a key in a lock cylinder must be rotated twice through 360 °. In the case of bar locks, the bars of which extend on both sides of a door, four turns of the key in the lock cylinder are usually necessary.
- knob cylinder in which a knob on the housing side replaced the key.
- the knob is directly connected to a cylinder core on one side of the double lock cylinder.
- Rotating a single key requires multiple grasping of the key crop.
- the keychain key ring, key chain
- the entire keychain must be rotated.
- a swivel joint between the keychain and the key inserted in the lock cylinder does not help much, because it is not easy to perform a relative movement between the key and the keychain with multiple embracing thumb and forefinger.
- the door leaf, door frame and pusher plate are trimmed and scratched by the frequent locks.
- a keychain device in which a plurality of flat keys between two elongated plates is pivotally mounted. In the manner of a pocket knife, the keys - similar to the blades of the pocket knife - are pivoted into the position of use. When locking the entire keyring device must be rotated.
- the DE 8505406 U concerns a key knob.
- a circular cylindrical body is attached to a key of a flat key and fixed with the help of worm screws. If this key remains permanently in the lock, then the cylinder has the function of a knob cylinder.
- the knob acts as a rotation aid during the locking process.
- the DE 4433122 A refers to a motorized door lock drive. About a pusher plate with lock cylinder, a drive box is slipped, in which a key is installed electrically rotatable. By turning on the electric drive, the key is turned and the trigger is pressed. This version is extremely complex and only suitable for stationary operation.
- the invention aims to facilitate the locking or opening operation while avoiding damage around the lock.
- the key is formed as a crank with eccentric crank handle for rotating the key in the lock cylinder. It can therefore have the key even the shape of a crank or attack a key on the crayon.
- the key shaft or beard can pass directly into a crank.
- crank handle is freely rotatably mounted relative to the key and preferably has an opening or an eye for a key chain or for a key ring of a keychain at the free end of the crank handle.
- the crank handle is the part of the crank where you attack with your thumb and forefinger. This remains rotatable and does not slide between the fingers. Therefore, a keychain does not rotate during the locking process when the key ring engages through the opening or the eye of the freely rotatable crank handle.
- a pivot bearing may be provided at the base of the crank handle on the key blade or a crank leg.
- a sleeve is freely rotatably mounted on the crank handle and if at the free end of the sleeve an opening or an eye for a key chain or for a key ring of a keychain is provided.
- the sleeve is arranged with play on the crank handle.
- the sleeve is here equipped with an opening or an eye for the key ring of the keychain.
- a practice-oriented compact embodiment is characterized in that the crank or the crank handle can be folded radially into the key crenellation or can be pushed in linearly for countersinking in the recess. The crank is thus placed in the waiting position on the side surfaces of the key grain and snaps into this position. It is also possible to lower the crank by inserting it into the Reide.
- crank is designed as an angle piece with two legs closing at right angles to each other, wherein the one leg with the key crop folded or swung connected or inserted into the crayon and the other leg forms the crank handle.
- the lever arm of the crank should be as large as possible, so that a maximum torque can be achieved.
- a pivot bearing for unfolding or pivoting the crank on the outer edge of the key crop at a radial distance from the axis of rotation of the key or a cylinder core in the lock cylinder is provided.
- lock cylinders are known as Knaufzylinder or hotel cylinder and require room side to open and close no key - this is formed by the knob in the sense of a permanently stuck key.
- the invention thus relates equally to a knob on a lock cylinder, which is provided according to a key to lock the lock cylinder. To make this knob easier to rotate, the invention provides that the knob is designed as a crank with an eccentric to the axis of rotation of the knob arranged crank handle.
- crank or the crank handle can be folded out on the knob or be swung out.
- the crank is formed as an angle piece with two legs closing at right angles to each other, wherein the one leg is hinged or swung connected to the knob or laterally inserted into the knob and the other leg the crank handle, possibly with Sleeve, forming.
- Fig. 1 shows the side view of a flat key with key and crank handle
- Fig. 2 a flat key in side view with fold-out crank
- Fig. 3 a double lock cylinder with knob and fold-out crank from the side
- Fig. 4 the front view on the knob

- a flat key comprises a key shank 1 with profiling and toothing or another coding and a key grain 2.
- a crank handle 3 is provided, on which a sleeve 4 is mounted captive and rotatable.
- the sleeve 4 carries an opening 5 for threading the key on a key ring of a keychain.
- the keychain remains in the cupped hand.
- thumb and forefinger the sleeve 4 is gripped and it is a rotating movement (crank movement) carried out.
- the lock cylinder is thus “cranked” or “cranked”. In particular, with bar locks with many turns, this is a relief and prevents knocking or scratching of the door leaf, stick or pusher plate, because the keychain does not rotate in the hand.
- Fig. 2 shows an improved embodiment with greater eccentricity of the crank 6.
- the side of the cog 2 as a crank 6 an angle of two right angles to each other legs 7, 8 is mounted on the outside swinging out.
- Leg 7 stands with a Pivot bearing 9 in conjunction and leg 8 carries as a crank handle the freely rotatable sleeve 9.
- An opening 10 is located with folded crank 6 approximately in the axis of rotation of the key. If the crank 6 in the position 6 'unfolded, then the leg 7' increases the cranks eccentricity.
- the sleeve 9 ' is received between the thumb and forefinger and circular movements are performed.
- the recorded in the opening 10 'key ring of the keychain does not rotate during the locking process in the hollow hand. Both the multiple locks is facilitated as well as damage to the keychain avoided.
- the Fig. 3 and 4 show a knob cylinder.
- a knob 12 is provided instead of a key.
- This has in the end face on a diagonal groove 13, in which a crank 14 is pivoted with rotatable sleeve 15 (shown in phantom). The swung out state is shown with solid lines.

Abstract
Description
Die Erfindung betrifft einen Schlüssel, insbesondere einen Flachschlüssel für einen Schließzylinder, mit Schlüsselschaft und Schlüsselreide und ferner einen Knauf an einem Schließzylinder, der einem Schlüssel entsprechend zum Sperren des Schließzylinders vorgesehen ist.The invention relates to a key, in particular a flat key for a lock cylinder, with key shank and key grain and also a knob on a lock cylinder, which is provided according to a key to lock the lock cylinder.
Um einen Riegel in einem Einstemmschloss vollständig in das stockseitige Schließstück einzuschieben, muss ein Schlüssel in einem Schließzylinder zweimal um 360° gedreht werden. Bei Balkenschlössern, deren Riegel zu beiden Seiten einer Tür ausfahren, sind zumeist vier Umdrehungen des Schlüssels im Schließzylinder notwendig.In order to fully insert a latch in a mortise lock in the stock-side striker, a key in a lock cylinder must be rotated twice through 360 °. In the case of bar locks, the bars of which extend on both sides of a door, four turns of the key in the lock cylinder are usually necessary.
Gleiches gilt für Knaufzylinder, bei welchen ein Knauf wohnungsseitig den Schlüssel ersetzt. Der Knauf ist direkt mit einem Zylinderkern auf einer Seite des Doppelschließzylinders verbunden. Das Drehen eines Einzelschlüssels erfordert ein mehrfaches Umgreifen an der Schlüsselreide. Insbesondere wenn der Schlüssel an einem Schlüsselbund (Schlüsselring, Schlüsselkette) hängt, muss der gesamte Schlüsselbund mitgedreht werden. Auch ein Wirbelgelenk zwischen dem Schlüsselbund und dem im Schließzylinder steckenden Schlüssel hilft nicht viel, da es nicht einfach ist, eine Relativbewegung zwischen der Schlüsselreide und dem Schlüsselbund bei mehrfachem Umgreifen von Daumen und Zeigefinger auszuführen. Wie die Praxis beweist, sind Türblatt, Türstock und Drückerschild durch das häufige Sperren abgeschürft und zerkratzt.The same applies to knob cylinder, in which a knob on the housing side replaced the key. The knob is directly connected to a cylinder core on one side of the double lock cylinder. Rotating a single key requires multiple grasping of the key crop. In particular, when the key hangs on a keychain (key ring, key chain), the entire keychain must be rotated. Also, a swivel joint between the keychain and the key inserted in the lock cylinder does not help much, because it is not easy to perform a relative movement between the key and the keychain with multiple embracing thumb and forefinger. As the practice proves, the door leaf, door frame and pusher plate are trimmed and scratched by the frequent locks.

Die Erfindung zielt darauf ab, den Sperr- oder Öffnungsvorgang zu erleichtern und gleichzeitig Beschädigungen rund um das Schloss zu vermeiden.The invention aims to facilitate the locking or opening operation while avoiding damage around the lock.
Dies wird mit einem Schlüssel der eingangs beschriebenen Art dadurch erreicht, dass die Schlüsselreide als Kurbel mit exzentrischem Kurbelgriff zur Drehung des Schlüssels im Schließzylinder ausgebildet ist. Es kann also die Schlüsselreide selbst die Form einer Kurbel haben oder an der Schlüsselreide eine Kurbel angreifen. Der Schlüsselschaft bzw. Bart kann unmittelbar in eine Kurbel übergehen.This is achieved with a key of the type described above, characterized in that the key is formed as a crank with eccentric crank handle for rotating the key in the lock cylinder. It can therefore have the key even the shape of a crank or attack a key on the crayon. The key shaft or beard can pass directly into a crank.
Es ist zweckmäßig, wenn der Kurbelgriff frei drehbar gegenüber dem Schlüssel gelagert ist und am freien Ende des Kurbelgriffes vorzugsweise eine Öffnung bzw. ein Auge für eine Schlüsselkette oder für einen Schlüsselring eines Schlüsselbundes aufweist. Der Kurbelgriff ist jener Teil der Kurbel, an dem man mit Daumen und Zeigefinger angreift. Dieser bleibt drehfest und gleitet nicht zwischen den Fingern. Daher rotiert auch ein Schlüsselbund nicht beim Sperrvorgang, wenn der Schlüsselring durch die Öffnung bzw. das Auge des frei drehbaren Kurbelgriffes greift. Ein Drehlager kann am Fußpunkt des Kurbelgriffes an der Schlüsselreide oder einem Kurbelschenkel vorgesehen sein.It is useful if the crank handle is freely rotatably mounted relative to the key and preferably has an opening or an eye for a key chain or for a key ring of a keychain at the free end of the crank handle. The crank handle is the part of the crank where you attack with your thumb and forefinger. This remains rotatable and does not slide between the fingers. Therefore, a keychain does not rotate during the locking process when the key ring engages through the opening or the eye of the freely rotatable crank handle. A pivot bearing may be provided at the base of the crank handle on the key blade or a crank leg.
Besonders zweckmäßig ist es, wenn auf dem Kurbelgriff eine Hülse frei drehbar gelagert ist und wenn am freien Ende der Hülse eine Öffnung bzw. ein Auge für eine Schlüsselkette oder für einen Schlüsselring eines Schlüsselbundes vorgesehen ist. Als Alternative zum frei drehbaren Kurbelgriff ist also die Hülse mit Spiel auf dem Kurbelgriff angeordnet. Die Hülse ist hier mit einer Öffnung oder einem Auge für den Schlüsselring des Schlüsselbundes ausgestattet.It is particularly useful if a sleeve is freely rotatably mounted on the crank handle and if at the free end of the sleeve an opening or an eye for a key chain or for a key ring of a keychain is provided. As an alternative to the freely rotatable crank handle so the sleeve is arranged with play on the crank handle. The sleeve is here equipped with an opening or an eye for the key ring of the keychain.
Eine praxisgerechte kompakte Ausführungsform ist dadurch gekennzeichnet, dass die Kurbel bzw. der Kurbelgriff in die Schlüsselreide radial einklappbar bzw. zur Versenkung in der Reide linear einschiebbar ist. Die Kurbel legt sich somit in der Wartestellung an die Seitenflächen der Schlüsselreide an und rastet in dieser Stellung ein. Auch ein Versenken der Kurbel durch Einschieben in die Reide ist möglich.A practice-oriented compact embodiment is characterized in that the crank or the crank handle can be folded radially into the key crenellation or can be pushed in linearly for countersinking in the recess. The crank is thus placed in the waiting position on the side surfaces of the key grain and snaps into this position. It is also possible to lower the crank by inserting it into the Reide.
Dabei ist es vorteilhaft, wenn die Kurbel als Winkelstück mit zwei im rechten Winkel aneinander schließenden Schenkeln ausgebildet ist, wobei der eine Schenkel mit der Schlüsselreide ausklappbar bzw. ausschwenkbar verbunden bzw. in die Schlüsselreide einschiebbar ist und der andere Schenkel den Kurbelgriff bildet.It is advantageous if the crank is designed as an angle piece with two legs closing at right angles to each other, wherein the one leg with the key crop folded or swung connected or inserted into the crayon and the other leg forms the crank handle.
Der Hebelarm der Kurbel soll möglichst groß sein, damit ein maximales Drehmoment erzielt werden kann. Dazu ist ein Drehlager zum Ausklappen oder Ausschwenken der Kurbel am äußeren Rand der Schlüsselreide im radialen Abstand von der Drehachse des Schlüssels bzw. eines Zylinderkernes im Schließzylinder vorgesehen.The lever arm of the crank should be as large as possible, so that a maximum torque can be achieved. For this purpose, a pivot bearing for unfolding or pivoting the crank on the outer edge of the key crop at a radial distance from the axis of rotation of the key or a cylinder core in the lock cylinder is provided.
Ein Äquivalent zum Schlüssel stellt der Knauf an der Einbauinnenseite eines Schließzylinders - meist Doppelschließzylinders - dar. Solche Schließzylinder sind als Knaufzylinder oder Hotelzylinder bekannt und erfordern raumseitig zum Öffnen und Schließen keinen Schlüssel - dieser wird durch den Knauf im Sinne eines permanent steckenden Schlüssels gebildet. Die Erfindung bezieht sich somit gleichermaßen auf einen Knauf an einem Schließzylinder, der einem Schlüssel entsprechend zum Sperren des Schließzylinders vorgesehen ist. Um diesen Knauf leichter zu drehen ist erfindungsgemäß vorgesehen, dass der Knauf als Kurbel mit einem exzentrisch zur Drehachse des Knaufes angeordneten Kurbelgriff ausgebildet ist.An equivalent to the key is the knob on the inner side of a lock cylinder - usually double lock cylinder - is. Such lock cylinders are known as Knaufzylinder or hotel cylinder and require room side to open and close no key - this is formed by the knob in the sense of a permanently stuck key. The invention thus relates equally to a knob on a lock cylinder, which is provided according to a key to lock the lock cylinder. To make this knob easier to rotate, the invention provides that the knob is designed as a crank with an eccentric to the axis of rotation of the knob arranged crank handle.
Die Kurbel bzw. der Kurbelgriff kann an dem Knauf ausklappbar bzw. ausschwenkbar sein. Insbesondere ist es zweckmäßig, wenn die Kurbel als Winkelstück mit zwei im rechten Winkel aneinander schließenden Schenkeln ausgebildet ist, wobei der eine Schenkel ausklappbar bzw. ausschwenkbar mit dem Knauf verbunden bzw. in den Knauf seitlich einschiebbar ist und der andere Schenkel den Kurbelgriff, gegebenenfalls mit Hülse, bildet.The crank or the crank handle can be folded out on the knob or be swung out. In particular, it is advantageous if the crank is formed as an angle piece with two legs closing at right angles to each other, wherein the one leg is hinged or swung connected to the knob or laterally inserted into the knob and the other leg the crank handle, possibly with Sleeve, forming.
