Description

Die Erfindung betrifft eine Drehgriffeinheit, insbesondere für Fenster und Türen, umfassend ein Lager und einen in dem Lager gelagerten Drehgriffkörper, wobei in einer zur Drehachse der Drehgriffeinheit parallelen Ausnehmung des Drehgriffkörpers ein Schliesszylinder verschiebbar geführt ist, welcher in seiner lagernahen Stellung ein Sperrglied in eine Sperrgliedausnehmung des Lagers eindringen lässt und in einer lagerfernen Stellung dieses Sperrglied ausser Eingriff mit der Sperrgliedausnehmung treten lässt, wobei weiter in dem Drehgriffkörper Vorspannmittel vorgesehen sind, welche den Schliesszylinder in die lagerferne Stellung vorspannen und wobei an dem Schliesszylinder eine federnd vorgespannte Sperrklinke vorgesehen ist, welche beim Einschieben des Schliesszylinders in seine lagernahe Stellung in eine Rastausnehmung des Drehgriffkörpers einrastet und durch Drehung des Schliesszylinderkerns gegenüber dem Schliesszylindergehäuse aus dem Rasteingriff lösbar ist.The invention relates to a twist grip unit, in particular for windows and doors, comprising a bearing and a twist grip body mounted in the bearing, a locking cylinder being displaceably guided in a recess of the twist grip body parallel to the axis of rotation of the twist grip unit, said locking cylinder being in its position close to the bearing in a blocking element recess of the bearing can penetrate and, in a position remote from the bearing, this locking member can disengage from the locking member recess, further tensioning means are provided in the twist grip body, which bias the locking cylinder into the position remote from the bearing, and wherein a resiliently preloaded pawl is provided on the locking cylinder, which is provided in the Inserting the locking cylinder into its position close to the bearing engages in a locking recess in the rotary handle body and can be released from the locking engagement by rotating the locking cylinder core relative to the locking cylinder housing.

Eine solche Drehgriffeinheit ist durch offenkundige Vorbenutzung bekannt.Such a twist grip unit is known from prior public use.

Bei der bekannten Drehgriffeinheit ist die Sperrklinke in dem Gehäuse des Schliesszylinders geführt und durch ein mit dem Zylinderkern des Schliesszylinders verbundenes Steuerglied aus ihrer Raststellung in ihre Freigabestellung zurückziehbar, wenn der Zylinderkern des Schliesszylinders gedreht wird. Die Unterbringung der Sperrklinke und des Steuerglieds innerhalb des Schliesszylinders bereitet Schwierigkeiten, da der Schliesszylinder mit verhältnismässig kleinem Profil ausgeführt werden soll, um in dem Drehgriffkörper ohne Überdimensionierung des letzteren Platz zu finden. Diese Schwierigkeiten sind zwar im Prinzip lösbar, verteuern aber die Herstellung der Drehgriffeinheit.In the known twist grip unit, the pawl is guided in the housing of the locking cylinder and can be withdrawn from its locking position into its release position by a control element connected to the cylinder core of the locking cylinder when the cylinder core of the locking cylinder is rotated. The accommodation of the pawl and the control member within the lock cylinder presents difficulties, since the lock cylinder should be designed with a relatively small profile in order to find space in the twist grip body without overdimensioning the latter. Although these difficulties can be solved in principle, they make the manufacture of the twist grip unit more expensive.

Der Erfindung liegt die Aufgabe zugrunde, eine Drehgriffeinheit der eingangs bezeichneten Art so auszugestalten, dass die Sperrklinke und die für deren Steuerung notwendigen Organe einfacher und kostengünstiger hergestellt werden können.The invention has for its object to design a twist grip unit of the type mentioned in such a way that the pawl and the organs necessary for its control can be manufactured more easily and cost-effectively.

Zur Lösung dieser Aufgabe wird erfindungsgemäss vorgeschlagen, dass die Sperrklinke an einem mit dem Schliesszylinderkern an dessen lagernahem Ende drehfest verbundenen Schwenkteil angebracht ist und dass die Ausnehmung mit einer Nockenfläche ausgeführt ist, welche beim Drehen des Schliesszylinderkerns die Sperrklinke aus der Rastausnehmung herausführt.To achieve this object, it is proposed according to the invention that the pawl is attached to a pivoting part connected to the locking cylinder core at its end near the bearing, and that the recess is designed with a cam surface which leads the locking pawl out of the locking recess when the locking cylinder core is rotated.

Weitere Merkmale der Erfindung, die auf einfache und platzsparende Herstellung sowie hohen Sicherheitswert der Drehgriffeinheit abstellen, sind in den Unteransprüchen behandelt.Further features of the invention, which are based on simple and space-saving production as well as a high safety value of the twist grip unit, are dealt with in the subclaims.

Die beiligenden Figuren erläutern die Erfindung. Es stellen dar:

  • Fig. 1 einen Längsschnitt durch eine erfindungsgemässe Drehgriffeinheit,
  • Fig. 2 einen Schnitt nach Linie 11-11 der Fig. 1, jedoch in einer anderen Betriebsstellung,
  • Fig. 3 einen Schnitt nach Linie 111-111 der Fig. 1 und
The accompanying figures explain the invention. They represent:
  • 1 shows a longitudinal section through a twist grip unit according to the invention,
  • 2 shows a section along line 11-11 of FIG. 1, but in a different operating position,
  • Fig. 3 is a section along line 111-111 of Fig. 1 and

Fig. 1 einen Schnitt nach Linie IV-IV der Fig. 2.1 shows a section along line IV-IV of FIG. 2nd

In den Figuren ist ein Lager, genannt Lagerplatte oder Rosette, mit 10 bezeichnet. Diese Lagerplatte 10 weist Bohrungen 12 auf. die zur Aufnahme von Befestigungsschrauben dienen, beispielsweise zur Befestigung der Lagerplatte 10 an einem Fensterflügel. Die Bohrungen 12 werden nach Einsetzen der nicht eingezeichneten Befestigungsschrauben durch einen Stöpsel 14, beispielsweise aus Kunststoff. verblockt, welcher so straff in der Bohrung sitzt, dass er nur durch Ausbohren entfernt werden kann. In der Lagerplatte 10, und zwar in einer Zentralbohrung 16 dieser Lagerplatte, ist ein Drehgriffkörper 18 mittels eines Drehzapfens 20 gelagert. Der Drehzapfen 20 ist durch einen Haltering 24 in axialer Richtung festgelegt. In dem Haltering 24 sind Löcher 26 vorgesehen. Diese Löcher treten in den verschiedenen funktionsbedingten Drehstellungen des Drehgriffkörpers in Flucht mit einer Bohrung 28 der Lagerplatte 10. Die Bohrung 28 nimmt eine durch eine Feder 30 vorgespannte Kugel 32 auf, so dass durch das Zusammenwirken der Kugel 32 und der Löcher 26 eine fühlbare Auszeichnung der Funktionsstellungen vor anderen Stellungen besteht. In dem Drehzapfen 20 ist eine polygonale Ausnehmung 34 vorhanden, die einen prismatischen Stift 36 zur Übertragung der Drehbewegung beispielsweise auf das Betätigungsgestänge eines Drehkippbeschlags ermöglicht.In the figures, a bearing, called a bearing plate or rosette, is designated by 10. This bearing plate 10 has bores 12. which are used to hold fastening screws, for example for fastening the bearing plate 10 to a window sash. The bores 12 are after insertion of the mounting screws, not shown, by a plug 14, for example made of plastic. blocked, which is so tight in the hole that it can only be removed by drilling. In the bearing plate 10, namely in a central bore 16 of this bearing plate, a twist grip body 18 is mounted by means of a pivot pin 20. The pivot pin 20 is fixed in the axial direction by a retaining ring 24. Holes 26 are provided in the retaining ring 24. These holes occur in the various function-related rotational positions of the rotary handle body in alignment with a bore 28 of the bearing plate 10. The bore 28 receives a ball 32 preloaded by a spring 30, so that the interaction of the ball 32 and the holes 26 gives a tangible distinction to the Functional positions exist before other positions. In the pivot pin 20 there is a polygonal recess 34, which enables a prismatic pin 36 for transmitting the rotary movement, for example, to the actuating linkage of a turn-tilt fitting.

In dem Drehgriffkörper 18 ist eine Ausnehmung 38 vorgesehen, welche einen Schliesszylinder 40 aufnimmt. Der Schliesszylinder umfasst eine Schliesszylindergehäuse 42 und einen Schliesszylinderkern 44. Der Schliesszylinder ist mit üblichen Stiftzuhaltungen 46 ausgeführt und wird durch einen Flachschlüssel betätigt. Bei eingestecktem Flachschlüssel geben die Stiftzuhaltungen die Drehbewegung des Zylinderkerns 44 frei.A recess 38 is provided in the rotary handle body 18, which receives a locking cylinder 40. The locking cylinder comprises a locking cylinder housing 42 and a locking cylinder core 44. The locking cylinder is designed with conventional pin tumblers 46 and is actuated by a flat key. When the flat key is inserted, the pin tumblers release the rotary movement of the cylinder core 44.

Der Schliesszylinder 40 ist in der Ausnehmung 38 axial verschiebbar zwischen einer lagerfernen Stellung, die in Fig. 1 gezeichnet ist, und einer lagernahen Stellung, die in Fig. 2 gezeichnet ist. Der axiale Verschiebeweg des Schliesszylinders 40 ist durch eine achsparallele Längsnut 48 begrenzt. In diese Längsnut 48 greift eine Madenschraube 50 ein, welche von der schwer zugänglichen unteren Seite 52 des Drehgriffkörpers 18 her eingeführt ist. An die Ausnehmung 38 grenzt eine Sackbohrung 54 an, welche eine Schraubendruckfeder 56 aufnimmt. Die Schraubendruckfeder 56 spannt den Schliesszylinder 40 in seine in Fig. 1 gezeichnete lagerferne Stellung vor.The locking cylinder 40 is axially displaceable in the recess 38 between a position remote from the bearing, which is shown in FIG. 1, and a position close to the bearing, which is shown in FIG. 2. The axial displacement of the locking cylinder 40 is limited by an axially parallel longitudinal groove 48. A grub screw 50 engages in this longitudinal groove 48 and is inserted from the hard-to-access lower side 52 of the rotary handle body 18. A blind bore 54 adjoins the recess 38 and receives a helical compression spring 56. The helical compression spring 56 biases the locking cylinder 40 into its position remote from the bearing shown in FIG. 1.

Der Zylinderkern des Schliesszylinders 40 besitzt einen über das Zylindergehäuse 42 nach unten vorspringenden Fortsatz 58. Dieser Fortsatz '58 ist in der Stellung der Fig. 1 bis oberhalb die Trennlinie zwischen Lagerplatte 10 und Griffkötpe- 18 zurückgezogen. In der Stellung der Fig. 2 jedoch ist der Fortsatz 58 bis über die Trennebene hinunter nach unten verschoben, so dass er in eine Ausnehmung 60 der Lagerplatte 10 eingreift. Die Ausnehmung 60 ist eine von vier Ausnehmungen, von denen in Fig. 2 weitere zwei gestrichelt eingezeichnet sind. Diese Ausnehmungen sind mit Abständen von 90° um die Drehachse des Drehzapfens 20 herum verteilt in der Lagerplatte 10 angeordnet. Wenn der Fortsatz 58, im folgenden Sperrglied genannt, in eine der Ausnehmungen 60 der Lagerplatte 10, im folgenden Sperrgliedausnehmungen genannt, eingreift, so ist der Drehgriffkörper 18 gegen Drehung relativ zu der Lagerplatte 10 gesperrt; dies trifft in der Stellung der Fig. 2 zu.The cylinder core of the lock cylinder 40 be sits an extension 58 projecting downward over the cylinder housing 42. In the position of FIG. 1, this extension 58 is retracted to above the dividing line between the bearing plate 10 and Griffkötpe- 1 8. In the position of FIG. 2, however, the extension 58 is shifted downward beyond the parting plane, so that it engages in a recess 60 in the bearing plate 10. The recess 60 is one of four recesses, two of which are shown in broken lines in FIG. 2. These recesses are arranged at intervals of 90 ° around the axis of rotation of the pivot pin 20 in the bearing plate 10. When the extension 58, hereinafter referred to as the locking member, engages in one of the recesses 60 of the bearing plate 10, hereinafter referred to as the locking member recesses, the twist grip body 18 is locked against rotation relative to the bearing plate 10; this applies in the position of FIG. 2.

In der Mantelfläche 62 der Ausnehmung 38 ist eine als Nockenfläche wirkende Rastausnehmung in Form einer mondsichelförmigen Aussparung 64 vorgesehen. In einem mit dem Zylinderkern 44 verbundenen Schwenkteil 66 des Schliesszylinders 40 ist, wie aus Fig. 2 ersichtlich, von einer Radialbohrung 68 eine Sperrklinke in Form eines Sperrstifts 70 aufgenommen, welcher durch eine Schraubendruckfeder 72 nach radial aussen vorgespannt ist und durch eine Schulter 74 an einer Andrehung 76 der Bohrung 68 anschlägt. Dieser Sperrstift 70 rastet beim Abwärtsdrücken des Schliesszylinders 40 aus der Stellung der Fig. 1 in die Stellung der Fig. 2 hinter die Verrastungsfläche 78 der mondsichelförmigen Aussparung 64 ein, so dass der Schliesszylinder 40 nicht mehr in die Stellung nach Fig. 1 zurückkehren kann. Natürlich kann der Schliesszylinder 40 nur dann aus der Stellung gemäss Fig. 1 in die Stellung nach Fig. 2 abwärts gedrückt werden, wenn sich das Sperrglied 58 in Flucht mit einer Sperrgliedausnehmung 60 befindet. Diese Fluchtstellung ist aber durch die Wechselwirkung der Kugel 32 und der Löcher 26 fühlbar.In the lateral surface 62 of the recess 38, a latching recess acting as a cam surface is provided in the form of a crescent-shaped recess 64. 2, a pawl in the form of a locking pin 70 is received by a radial bore 68, which is biased radially outward by a helical compression spring 72 and by a shoulder 74 in a pivoting part 66 of the locking cylinder 40 connected to the cylinder core 44 a turn 76 of the bore 68 strikes. This locking pin 70 engages when the locking cylinder 40 is pressed down from the position in FIG. 1 into the position in FIG. 2 behind the locking surface 78 of the crescent-shaped recess 64, so that the locking cylinder 40 can no longer return to the position shown in FIG. 1. Of course, the locking cylinder 40 can only be pressed down from the position shown in FIG. 1 into the position shown in FIG. 2 when the locking member 58 is in alignment with a locking member recess 60. This escape position can be felt by the interaction of the ball 32 and the holes 26.

Will man die Drehgriffeinheit wieder entsperren, so ist es notwendig, mit dem in den Zylinderkern 44 eingeführten Flachschlüssel den Zylinderkern 44 zu drehen. Beim Drehen wird der Sperrstift 70 durch die Wechselwirkung seines radial äusseren Endes mit der Umfangsfläche der mondsichelförmigen Aussparung 64 radial zurückgedrückt, bis er wieder in der Umfangsfläche 62 der Aussparung 38 liegt, dann springt der Schliesszylinder 40 unter der Wirkung der Vorspannfeder 56 nach oben und die Sperre ist gelöst.If you want to unlock the twist grip unit again, it is necessary to turn the cylinder core 44 with the flat key inserted in the cylinder core 44. When turning, the locking pin 70 is pushed back radially by the interaction of its radially outer end with the peripheral surface of the crescent-shaped recess 64 until it is again in the peripheral surface 62 of the recess 38, then the locking cylinder 40 jumps up under the action of the biasing spring 56 and the Lock is released.

Nachzutragen ist noch, dass in dem Drehzapfen 20 eine Ausnehmung 82 gebildet ist, welche in der lagernahen Stellung des Schliesszylinders 40 das Sperrglied 58 aufnimmt.It must also be added that a recess 82 is formed in the pivot pin 20, which receives the locking member 58 in the position of the locking cylinder 40 near the bearing.
