Description

Technisches GebietTechnical area

Die Erfindung bezieht sich auf ein Schloss gemäß dem Oberbegriff des Anspruches 1, und wie zum Beispiel aus der EP 1 624 140 A2 bekannt.The invention relates to a lock according to the preamble of claim 1, and as for example from EP 1 624 140 A2 known.

Stand der TechnikState of the art

Bei derartigen Schlössern ist ein Fallenhebel vorgesehen, der bei einem Verschieben der Schubstange in Richtung der Offenstellung der Riegelelemente von der Schubstange mitgenommen und verschwenkt wird, wodurch die Falle zurückgezogen wird. Dabei ergibt sich das Problem, dass bei der Herstellung der erforderlichen Einzelteile Toleranzen unvermeidbar sind. Dadurch können sich Probleme in der Weise ergeben, dass die Riegel der Mehrfachverriegelung nicht vollständig zurückgezogen werden können, da nach vollständigem Einziehen der Falle kein weiterer Hubweg für die Schubstange mehr verbleibt, wodurch sich entsprechende Probleme beim Betrieb einer solchen Mehrfachverriegelung ergeben.In such locks, a latch lever is provided, which is taken along with a displacement of the push rod in the direction of the open position of the locking elements of the push rod and pivoted, whereby the case is withdrawn. This results in the problem that tolerances are inevitable in the production of the required items. As a result, problems can arise in such a way that the latch of the multi-point lock can not be completely withdrawn, since after complete retraction of the trap no further stroke for the push rod remains, resulting in corresponding problems in the operation of such a multi-point lock.

Kurzbeschreibung der ErfindungBrief description of the invention

Ziel der Erfindung ist es, diesen Nachteil zu vermeiden und ein Schloss der eingangs erwähnten Art vorzuschlagen, das auch bei größeren Toleranzen einen einwandfreien Betrieb einer Mehrfachverriegelung ermöglicht.The aim of the invention is to avoid this disadvantage and to propose a lock of the type mentioned that allows for larger tolerances proper operation of a multiple locking.

Erfindungsgemäß wird dies durch die kennzeichnenden Merkmale des Anspruchs 1 erreicht.This is achieved by the characterizing features of claim 1 according to the invention.

Durch die vorgeschlagenen Maßnahmen ist sichergestellt, dass, bei einer/einem sich bereits in der zurückgezogenen Endlage befindlichen Falle, bzw. Fallenriegel, Riegel oder Schwenkriegel, die Schubstange noch um den Federweg des mit dieser zusammenwirkenden Fallenhebels weiterbewegt werden kann, um die über die Schubstange gesteuerten Zusatzriegel vollständig einziehen zu können. Es versteht sich, dass die Zusatzriegel ebenfalls beliebig ausgestaltet sein können.By the proposed measures it is ensured that, at a / already located in the retracted end position trap or latch bolt, latch or pivot bolt, the push rod can still be moved to the spring travel of this interacting with the latch lever to the over the push rod to be able to completely pull in the controlled additional bar. It is understood that the additional bolts can also be configured as desired.

Weiters kann, bei einem aufgrund von höheren auf die Falle, bzw. den Fallenriegel, Riegel oder Schwenkriegel, einwirkenden Seitenkräften auftretenden Klemmen der Falle in Schließstellung, die Schubstange um den Federweg bewegt werden, wonach durch den nach Überwindung des Federweges des federnd ausgebildeten Armes des Fallenhebels gegebenen Anschlag eine sichere Mitnahme der Falle bzw. des Fallenriegels sichergestellt ist. Dabei geht der federnd ausgebildete Arm des Fallenhebels nach dem Lösen der Klemmung wieder in seine Normallage zurück.Furthermore, at a due to higher on the case, or the latch bolt, bolt or pivot bolt, acting lateral forces occurring terminals of the latch in the closed position, the push rod to the spring travel are moved, after which given by overcoming the spring travel of the spring-trained arm of the latch lever stop secure entrainment of the case or the latch bolt is ensured. In this case, the spring-trained arm of the latch lever goes back to its normal position after releasing the clamp.

Aufgrund des Federweges des mit der Schubstange, bzw. mit deren Mitnehmer, zusammenwirkenden Armes des Fallenhebels können bei der Herstellung der einzelnen Teile eines erfindungsgemäßen Schlosses relativ große Toleranzen zugelassen werden, ohne dass es dadurch bei der Verwendung des Schlosses zu Problemen kommt.Due to the spring travel of the push rod, or with their driver, cooperating arm of the latch lever relatively large tolerances can be allowed in the production of the individual parts of a lock according to the invention, without thereby causing problems when using the lock.

Nach einem weiteren Merkmal können die Merkmale des Anspruches 2 vorgesehen sein. Auf diese Weise ergibt sich eine sehr einfache Konstruktion, wobei sich auch ein entsprechend kleiner Federweg ergibt und nach Überwindung des durch den Schlitz vorgegebenen Federwegs ein sicherer Anschlag und damit eine sichere Mitnahme des übrigen Fallenhebels sichergestellt ist.According to a further feature, the features of claim 2 may be provided. In this way, results in a very simple construction, which also results in a correspondingly small spring travel and after overcoming the predetermined by the slot travel a secure stop and thus secure entrainment of the remaining latch lever is ensured.

In diesem Zusammenhang ist es vorteilhaft, die Merkmale des Anspruches 3 vorzusehen, wodurch sich eine sehr günstige Federcharakteristik erreichen lässt.In this context, it is advantageous to provide the features of claim 3, which can achieve a very favorable spring characteristic.

Kurze Beschreibung der ZeichnungsfigurenShort description of the drawing figures

Die Erfindung wird nun anhand der Zeichnung näher erläutert, wobei sich die Beschreibung auf die wesentlichen Teile der Erfindung beschränkt. Dabei zeigen:

  • Fig. 1 ein erfindungsgemäßes Schloss mit ausgeschobenem Fallenriegel und der Schubstange in der Sperrstellung von Zusatzriegeln,
  • Fig. 2 das Schloss nach der Fig. 1 mit vollständig zurückgezogenem Fallenriegel, wobei sich die Schubstange in einer den zurückgezogenen Zusatzriegeln entsprechenden Stellung befindet, und
  • Fig. 3 das Schloss nach den Fig. 1 und 2 mit in einer Endstellung befindlicher Schubstange, wo der verbleibende Hub des Federwegs des Fallenhebels mit verwendet wird.
The invention will now be explained in more detail with reference to the drawing, wherein the description is limited to the essential parts of the invention. Showing:
  • Fig. 1 an inventive lock with ejected latch bolt and the push rod in the locked position of additional bolts,
  • Fig. 2 the castle after the Fig. 1 with fully retracted latch bolt, wherein the push rod is in a position corresponding to the retracted auxiliary bolts, and
  • Fig. 3 the castle after the Fig. 1 and 2 with in an end position located push rod, where the remaining stroke of the spring travel of the latch lever is used with.

Beschreibung der AusführungsartenDescription of the embodiments

Das Schloss ist mit abgenommenem Gehäusedeckel dargestellt. In einem Gehäuse 1 ist eine Kulisse 2 geführt, die zwei Teile einer Schubstange 3 miteinander verbindet, deren Antrieb nicht dargestellt ist und z.B. über einen Schließzylinder oder eine Nuss mit entsprechendem Getriebe erfolgen kann.The lock is shown with removed housing cover. In a housing 1, a link 2 is guided, which connects two parts of a push rod 3, whose drive is not shown and, for example. can be done via a lock cylinder or a nut with a corresponding gear.

In dem Gehäuse 1 ist weiters ein Fallenriegel 4 im Wesentlichen senkrecht zur Schubstange 3 verschiebbar gehalten. Dabei ist der Fallenriegel 4 von einer Fallenfeder 5 gegen seine in der Fig. 1 dargestellte ausgeschobene Stellung vorgespannt, wobei die Fallenfeder 5 an einem im Gehäuse 1 befestigten Zapfen 6 gehalten ist.In the housing 1 further a latch bolt 4 is held substantially perpendicular to the push rod 3 slidably. In this case, the latch bolt 4 by a latch spring 5 against his in the Fig. 1 shown biased position shown, wherein the latch spring 5 is held on a pin 6 fixed in the housing 1.

Ein um eine Achse 7 drehbar gehaltener Fallenhebel 8 greift mit einem Arm 9 in eine Nut 10 des Fallenriegels 4 ein und wird daher in Ausschieberichtung des Fallenriegels 4 von diesem mitgenommen und nimmt seinerseits den Fallenriegel 4 in Einschieberichtung des Fallenriegels 4 entgegen der Kraft der Fallenfeder 5 mit.An about an axis 7 rotatably held latch lever 8 engages with an arm 9 in a groove 10 of the latch bolt 4 and is therefore taken in Ausschieberichtung of the latch bolt 4 of this and in turn takes the latch bolt 4 in the insertion direction of the latch bolt 4 against the force of the latch spring fifth With.

Ein zweiter Arm 11 des Fallenhebels 8 liegt an einem Mitnehmer 12 der Kulisse 2 an, der somit mit der Schubstange 3 mitbewegt wird. Dieser zweite Arm 11 des Fallenhebels 8 weist einen randoffenen Schlitz 13 auf, der sich, wie dargestellt bis zu einer Bohrung 14 zur Aufnahme der Achse 7 erstreckt. Der Schlitz kann dabei, wie gezeigt, auch geknickt geführt sein. Dadurch ergibt sich eine Federwirkung über den Verbindungsbereich 15 der beiden Arme 9, 11 des Fallenhebels 8. Die Federkonstante der beiden durch den Schlitz 13 geteilten Teile des Armes 11 ist höher als jene der Fallenfeder 5, jedoch so gering wie möglich um eine flüssige Benutzung des gesamten Hubs des Schlosses zu ermöglichen.A second arm 11 of the latch lever 8 is applied to a driver 12 of the link 2, which is thus moved with the push rod 3. This second arm 11 of the latch lever 8 has an open-edged slot 13 which, as shown, extends as far as a bore 14 for receiving the axle 7. The slot can be guided, as shown, also kinked. This results in a spring action on the connecting portion 15 of the two arms 9, 11 of the latch lever 8. The spring constant of the two divided by the slot 13 parts of the arm 11 is higher than that of the latch spring 5, but as low as possible to a liquid use of entire hubs of the castle to allow.

Wird die Schubstange 3 nach oben in Richtung des Pfeils 16 verschoben, so wird der Fallenhebel 8 über seinen an dem Mitnehmer 12 anliegenden Arm 11 im Uhrzeigersinn verschwenkt und zieht über seinen Arm 9 den Fallenriegel 4 entgegen der Kraft der Fallenfeder 5 zurück (Fig. 2).If the push rod 3 is displaced upward in the direction of the arrow 16, then the latch lever 8 is pivoted clockwise about its arm 11 engaging on the catch 12 and pulls the latch bolt 4 back against the force of the latch spring 5 via its arm 9 (FIG. Fig. 2 ).

Reicht dabei der Weg der Schubstange 3 bis zum vollständigen Zurückziehen des Fallenriegels 4 nicht aus, um die von der Schubstange 3 ebenfalls gesteuerten, nicht dargestellten Zusatzriegel vollständig zurückzuziehen, so kann die Schubstange 3 um den Weg der Breite des Schlitzes 13 des Armes 11 des Fallenhebels 8 weiterbewegt werden (Fig.3). Dadurch können herstellungsbedingte Toleranzen sehr einfach ausgeglichen werden.In this case, the path of the push rod 3 is not sufficient for the complete retraction of the latch bolt 4, to completely withdraw the additional bar, not shown, also shown by the push rod 3, the push rod 3 to the way the width of the Slot 13 of the arm 11 of the latch lever 8 are moved further ( Figure 3 ). As a result, manufacturing tolerances can be easily compensated.

Falls es aufgrund von höheren auf den Fallenriegel 4 einwirkenden seitlichen Kräften zu einer Klemmung des Fallenriegels 4 in Schließstellung kommt, so kommt es bei einer Bewegung der Schubstange 3 in Richtung des Pfeils 16 (Fig. 1 und 2) zum Öffnen des Schlosses zuerst zu einem Zusammendrücken des Schlitzes 13 in dessen äußerem Bereich bis die beiden durch den Schlitz 13 getrennten Teile des Armes 11 in deren äußeren Bereichen aneinander anliegen und eine sichere Mitnahme des Armes 11 des Fallenhebels 8 erfolgt. Dadurch wird der Fallenhebel 8 verschwenkt und der Fallenriegel 4 in jedem Fall zurückgezogen. Sobald die Rückzugsbewegung des Fallenriegels 4 einsetzt und die Klemmwirkung aufgehoben ist, vermindert sich die für das Zurückziehen des Fallenriegels erforderliche Kraft und der Schlitz 13 öffnet sich wieder aufgrund der größeren Federkonstante. Falls bei Erreichung der zurückgezogenen Endstellung des Fallenriegels 4 noch ein Überhub zum vollständigen Zurückziehen der von der Schubstange 3 gesteuerten Zusatzriegel erforderlich sein sollte, so steht dieser Überhub durch Zusammendrücken des Schlitzes 13 wieder zur Verfügung.If it comes to a clamping of the latch bolt 4 in the closed position due to higher acting on the latch bolt 4 lateral forces, so it comes with a movement of the push rod 3 in the direction of arrow 16 (FIG. Fig. 1 and 2 ) To open the lock first to a compression of the slot 13 in its outer region until the two separated by the slot 13 parts of the arm 11 abut each other in the outer regions and a secure entrainment of the arm 11 of the latch lever 8 takes place. As a result, the latch lever 8 is pivoted and the latch bolt 4 is retracted in each case. As soon as the return movement of the latch bolt 4 starts and the clamping effect is released, the force required for the retraction of the latch bolt is reduced and the slot 13 opens again due to the larger spring constant. If, when the retracted end position of the latch bolt 4 is reached, an overstroke for the complete retraction of the additional bolt controlled by the push rod 3 is required, this overstroke is available again by compressing the slot 13.
