Description

Die Erfindung bezieht sich auf ein Schloss gemäß dem Oberbegriff des Anspruches 1.The invention relates to a lock according to the preamble of claim 1.

Stand der TechnikState of the art

Ein solches Schloss wurde z.B. durch die DE 614 907 bekannt. Bei diesem bekannten Schloss ragt ein Arm des Auslösehebels aus einer schräg zur Bewegungsrichtung der Falle verlaufenden Fläche des Fallenkopfes heraus. Dieser Arm wird daher beim Anschlagen der Falle an einem Schließblech betätigt und löst den federbelasteten Riegel aus, sodass dieser ausfährt. Der Verriegelungsmechanismus ist bei der bekannten Lösung durch ein über Kulissen gesteuertes Hebelsystem gebildet, wobei der zweite Arm des Auslösehebels auf dieses Hebelsystem einwirkt.Such a lock was eg by the DE 614 907 known. In this known lock, an arm of the release lever protrudes from an obliquely to the direction of movement of the trap extending surface of the case head. This arm is therefore actuated when striking the latch on a strike plate and triggers the spring-loaded latch so that it extends. The locking mechanism is formed in the known solution by a lever system controlled via scenes, wherein the second arm of the release lever acts on this lever system.

Bei dieser bekannten Lösung ergibt sich der Nachteil, dass der Riegel bereits beim Anschlagen der Falle an dem Schließblech ausgelöst wird und am Türstock oder dem Schließblech zur Anlage kommt und die weitere Bewegung der Tür behindert. Beim Schließen einer Tür ohne Betätigung eines Drückers kann es daher vorkommen, dass die Tür in einer Lage stehen bleibt, in der die Falle nur wenig in die entsprechende Öffnung des Schließbleches hineinragt und der Riegel mit seiner Stirnseite an dem Schließblech ansteht. In einem solchen Fall macht die Tür zwar einen geschlossenen Eindruck, kann aber sehr leicht aufgedrückt werden.In this known solution, there is the disadvantage that the bolt is triggered when striking the case on the strike plate and comes to rest on the door frame or the strike plate and hinders the further movement of the door. When closing a door without pressing a pusher, it may therefore happen that the door stops in a position in which the case only slightly protrudes into the corresponding opening of the striking plate and the bolt is present with its front side on the strike plate. In such a case, the door makes a closed impression, but can be very easily pressed.

Außerdem erfordert das Hebelsystem einen erheblichen Aufwand bei seiner Herstellung und es ergibt sich aufgrund der vielen bewegten Teile und Drehpunkte eine erhöhte Fehleranfälligkeit.In addition, the lever system requires considerable effort in its manufacture and it results due to the many moving parts and fulcrums an increased error rate.

Kurzbeschreibung der ErfindungBrief description of the invention

Ziel der Erfindung ist es, diese Nachteile zu vermeiden und ein Schloss der eingangs erwähnten Art vorzuschlagen, bei dem sichergestellt ist, dass der Riegel erst dann ausgelöst wird, wenn die Falle sicher in die entsprechende Öffnung des Schließblechs eingreift. Außerdem sollen die Anzahl der bewegten Teile gering gehalten werden, was sowohl die Herstellungskosten senkt, also auch die Schließsicherheit erhöht.The aim of the invention is to avoid these disadvantages and to propose a lock of the type mentioned, in which it is ensured that the bolt is triggered only when the trap securely engages in the corresponding opening of the striking plate. In addition, the number of moving parts to be kept low, which both lowers the cost, so also increases the security.

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

Durch die vorgeschlagenen Maßnahmen ist sichergestellt, dass der Auslösehebel erst beim Eindringen der Falle in die entsprechende Öffnung des Schließblechs betätigt wird und nicht bereits beim Anschlagen der Falle an dem Schließblech oder dem Türstock. Damit wird eine vorzeitige Auslösung des Riegels verhindert.By the proposed measures it is ensured that the release lever is actuated only when the trap enters the corresponding opening of the striking plate and not already when striking the case on the strike plate or the door frame. This prevents premature release of the bolt.

Um eine einfache Gestaltung des Verriegelungsmechanismus zu ermöglichen, können die Merkmale des Anspruches 2 vorgesehen werden. Auf diese Weise gelingt es mit einem Minimum an Einzelteilen das Auslangen zu finden, wobei, abgesehen vom Auslösehebel, alle Teile linear bewegt werden, wodurch eine geringe Fehleranfälligkeit gegeben ist.In order to enable a simple design of the locking mechanism, the features of claim 2 can be provided. In this way, it is possible with a minimum of individual parts to find Auslangen, which, apart from the release lever, all parts are moved linearly, whereby a low susceptibility to errors is given.

Dabei ist es vorteilhaft, die Merkmale des Anspruches 3 vorzusehen. Damit wird auf einfache Art und Weise eine Umsetzung der Bewegungen des Auslösehebels in eine senkrecht zu dieser verlaufenden Bewegung des Auslöseschiebers erreicht, wobei gleichzeitig die Falle mit dem darin angeordneten Auslösehebel für einen linken oder rechten Anschlag als Wendefalle eingesetzt werden kann.It is advantageous to provide the features of claim 3. This is achieved in a simple manner, an implementation of the movements of the release lever in a direction perpendicular to this movement of the release slide, while the case can be used with the therein arranged release lever for a left or right stop as a reversal trap.

Zum Entriegeln des Schlosses ist eine Schubstange zur Betätigung der Falle und des Riegels vorgesehen, welche vorteilhafterweise die kennzeichnenden Merkmale des Anspruches 4 aufweist. Dadurch wird eine einfache Steuerung der Falle und des Riegels sichergestellt, wobei sich diese Konstruktion durch Einfachheit auszeichnet.To unlock the lock a push rod for actuating the latch and the bolt is provided, which advantageously has the characterizing features of claim 4. This ensures a simple control of the latch and the bolt, this construction being characterized by simplicity.

Weiters ist es vorteilhaft, die Merkmale des Anspruches 5 vorzusehen, wodurch die Schubstange neben der Entsperrfunktion gleichzeitig als Rückdrücksicherung dient.Furthermore, it is advantageous to provide the features of claim 5, whereby the push rod at the same time as the unlocking function serves as a backup.

Beschreibung der AusführungsartenDescription of the embodiments

Wie aus der Fig. 1 zu ersehen ist, weist das erfindungsgemäße Schloss ein Gehäuse 1 auf, das durch einen Stulp 2 abgeschlossen ist. Dabei weist der Stulp 2 Öffnungen für den Durchtritt einer Falle 3 und eines Riegels 4 auf. In der Falle 3 ist ein zweiarmiger Auslösehebel 5 um eine parallel zur Längsrichtung des Stulps 2 verlaufende und in der Falle gehaltene Achse 6 (Fig. 5) schwenkbar gelagert. Das Schließstück 8 der Falle 3 weist eine Auflaufschräge 11 sowie eine rückseitige Anschlagfläche 10 auf.Like from the Fig. 1 can be seen, the lock according to the invention has a housing 1, which is closed by a face plate 2. In this case, the faceplate 2 openings for the passage of a case 3 and a bolt 4. In the case 3 is a two-armed release lever 5 about a parallel to the longitudinal direction of the faceplate 2 extending and held in the case axis 6 (FIG. Fig. 5 ) pivotally mounted. The closing piece 8 of the case 3 has a ramp 11 and a rear stop surface 10.

Dabei ragt der erste Arm 9 des Auslösehebels 5 aus der rückseitigen Anschlagfläche 10 des Schließstücks 8 vor.In this case, the first arm 9 of the release lever 5 protrudes from the rear abutment surface 10 of the closing piece 8.

Um den Bewegungsweg des Auslösehebels 5 zu begrenzen und dessen ersten Arm 9 gegen seine aus der rückseitigen Anschlagfläche 10 des Schließstücks 8 ragende Ruhestellung vorzuspannen, ist eine senkrecht zur Bewegungsrichtung der Falle 3 wirkende Feder 12 in das Schließstück 8 eingesetzt. (Fig. 5)In order to limit the movement path of the trigger lever 5 and to bias its first arm 9 against its projecting from the rear abutment surface 10 of the striker 8 rest position, a force acting perpendicular to the direction of movement of the case 3 spring 12 is inserted into the closing piece 8. ( Fig. 5 )

Weiters ragt, wie aus der Fig. 5 zu ersehen ist, ein Mitnahmezapfen 27 seitlich aus der Falle 3 vor, der mit einer Kulisse 28 einer Schubstange 23 zusammenwirkt und zur Steuerung der Falle 3 dient. Diese Kulisse 28 ist durch eine Ausnehmung der Schubstange 23 gebildet, die eine im Wesentlichen dreieckige Gestalt aufweist. (Fig. 2, 3, 4)Furthermore, as from the Fig. 5 can be seen, a driving pin 27 laterally from the case 3, which cooperates with a link 28 of a push rod 23 and serves to control the case 3. This gate 28 is formed by a recess of the push rod 23, which has a substantially triangular shape. ( Fig. 2 . 3 . 4 )

Wie aus der Fig. 5 weiter zu ersehen ist, greift der Auslösehebel 5 mit seinem zweiten Arm 13 in einen Durchbruch 15 eines Auslöseschiebers 14 ein. Dieser Durchbruch 15 weist zwei Schrägflächen 16 auf, an denen das freie Ende des zweiten Armes 13 des Auslösehebels 5 zur Anlage bringbar ist. Dabei liegt der zweite Arm 13 des Auslösehebels 5 in der Ruhestellung des Auslöseschiebers 14, die durch eine in Richtung des Pfeiles 17 wirkende Feder festgelegt ist, im Freiraum zwischen den beiden Schrägflächen 16.Like from the Fig. 5 can be seen, the trigger lever 5 engages with its second arm 13 in an opening 15 of a trip slider 14 a. This breakthrough 15 has two inclined surfaces 16 on which the free end of the second arm 13 of the release lever 5 can be brought into abutment. In this case, the second arm 13 of the release lever 5 is in the rest position of the release slider 14, which by a in the direction of Arrows 17 acting spring is fixed in the space between the two inclined surfaces 16th

An seiner dem Riegel 4 zugekehrten Seite weist der Auslöseschieber 14 einen Haltevorsprung 18 auf, der im Wesentlichen sägezahnförmig ausgebildet ist und eine Anzugsfläche 19 aufweist. Dieser Haltevorsprung 18 wirkt mit einer Raste 20 des Riegels 4 zusammen.On its side facing the latch 4, the trigger slide 14 has a holding projection 18, which is substantially sawtooth-shaped and has a tightening surface 19. This retaining projection 18 cooperates with a catch 20 of the bolt 4.

Der Riegel 4 ist durch eine Feder 7 gegen seine ausgefahrene Stellung vorgespannt. Der Riegel 4 ist in der Fig. 6 näher dargestellt und weist eine Raste 20 auf, die durch eine Vertiefung gebildet ist, in die der Haltevorsprung 18 des Auslöseschiebers 14 im zurückgezogenen Zustand des Riegels 4 eingreift und den Riegel 4 entgegen der in Richtung des Pfeiles 21 wirkenden Feder 7 in seiner zurückgezogenen Stellung hält.The latch 4 is biased by a spring 7 against its extended position. The latch 4 is in the Fig. 6 shown closer and has a catch 20 which is formed by a recess into which the retaining projection 18 of the trigger slide 14 engages in the retracted state of the bolt 4 and holds the bolt 4 against the force acting in the direction of arrow 21 spring 7 in its retracted position ,

Der Riegel 4 weist zwei durch Vertiefungen gebildete Freistellungen 22 auf, in die an einer Schubstange 23 angeordnete Rückdrücksicherungsbolzen 24 in der zurückgezogenen Stellung des Riegels 4 eingreifen und wobei die Rückdrucksicherungsbolzen 24 im ausgeschobenen Zustand des Riegels 4 an dessen hinterer Stirnwand im Bereich der vollen Dicke des Riegels 4 positioniert sind und diesen gegen ein Zurückschieben sichern.The latch 4 has two recesses formed by depressions 22, in the arranged on a push rod 23 back pressure securing bolt 24 engage in the retracted position of the bolt 4 and wherein the back pressure securing bolt 24 in the extended state of the bolt 4 at the rear end wall in the full thickness of the Bolt 4 are positioned and secure this against being pushed back.

Weiters ragt ein Mitnahmestift 25 seitlich aus dem Riegel 4 vor. Dieser wirkt mit einer Kulisse 26 zusammen, die durch eine im Wesentlichen dreieckige Ausnehmung der Schubstange 23 gebildet ist, in die der Mitnahmestift 25 eingreift(Fig. 2, 3, 4).Furthermore, a driving pin 25 projects laterally out of the latch 4. This cooperates with a gate 26, which is formed by a substantially triangular recess of the push rod 23, in which the driving pin 25 engages ( Fig. 2 . 3 . 4 ).

Bei der in der Fig. 2 dargestellten Stellung des Schlosses ist die Falle 3 ausgefahren und der Riegel 4 in seiner zurückgezogenen Stellung und wird durch den von der Feder 29 vorgespannten Auslöseschieber 14 gehalten, der mit seinem Haltevorsprung 18 in die durch eine Vertiefung gebildete Raste 20 des Riegels 4 eingreift. Die Rückdrücksicherungsbolzen 24 der Schubstange greifen in die durch Vertiefungen gebildeten Freistellungen 22 des Riegels 4 ein, wodurch die Schubstange in einer etwas angehobenen Stellung gehalten wird.When in the Fig. 2 illustrated position of the lock, the latch 3 is extended and the latch 4 in its retracted position and is held by the biased by the spring 29 release slide 14 which engages with its retaining projection 18 in the recess formed by a recess 20 of the bolt 4. The push-back bolts 24 of the push rod engage the indentations 22 of the latch 4, thereby maintaining the push rod in a slightly raised position.

Wird die Falle 3 durch Anheben der Schubstange 23 oder durch Auftreffen der Auflaufschräge 11 des Schließstücks 8 auf das Schließblech zurückgedrückt, so tritt der zweite Arm 13 des Auslösehebels 5 ungehindert zwischen den Schrägflächen 16 durch den Durchbruch 15 des Auslöseschiebers 14 hindurch. Beim Wiederaustritt des Schließstücks 8 in eine entsprechende Ausnehmung eines Schließbleches wird der Auslösehebel 5 verschwenkt, da der erste Arm 9, der aus der rückseitigen Anschlagfläche 10 des Schließstücks 8 vorragt, entgegen der Kraft der Feder 12 zurückgedrückt wird. Dadurch drückt der zweite Arm 13 des Auslösehebels 5 gegen eine der Schrägflächen 16 des Auslöseschiebers 14, wodurch dieser entgegen der Kraft der Feder 29 nach oben gedrückt wird und den Riegel 4 frei gibt.If the case 3 by lifting the push rod 23 or by hitting the ramp 11 of the closing piece 8 on the strike plate pushed back, so enters the second arm 13 of the release lever 5 unhindered between the inclined surfaces 16 through the opening 15 of the trigger slide 14 therethrough. Upon re-emergence of the closing piece 8 in a corresponding recess of a striking plate of the trigger lever 5 is pivoted, since the first arm 9, which protrudes from the rear abutment surface 10 of the locking piece 8, against the force of the spring 12 is pushed back. As a result, the second arm 13 of the release lever 5 presses against one of the inclined surfaces 16 of the release slider 14, whereby this is pressed against the force of the spring 29 upwards and the latch 4 is free.

Hat dieser seine ausgeschobene Endstellung, gegen die der Riegel 4 durch die Feder 7 vorgespannt ist, erreicht, so kommen die Rückdrücksicherungsbolzen 24 der Schubstange 23 außer Eingriff mit den Freistellungen 22 des Riegels 4 und die Schubstange 23 fällt nach unten und erreicht ihre untere Endstellung. (Fig. 3) In dieser Stellung stehen die Rückdrücksicherungsbolzen 24 in den Bewegungsweg des Riegels 4 und sichern diesen in der ausgeschobenen Stellung.Has this his pushed-end position, against which the latch 4 is biased by the spring 7, reached, so the Rückdrücksicherungsbolzen 24 of the push rod 23 out of engagement with the exemptions 22 of the bolt 4 and the push rod 23 falls down and reaches its lower end position. ( Fig. 3 ) In this position, the back pressure securing bolts 24 are in the path of movement of the bolt 4 and secure it in the extended position.

Wird aus dieser Stellung die Schubstange 23 mittels eines nicht dargestellten Schließzylinders oder eines Drückers nach oben verschoben, so gelangen zuerst die Rückdrücksicherungsbolzen 24 in die Bereiche der Freistellungen 22 und danach wird der Riegel 4 über die Kulisse 26 und dessen Mitnahmestift 25 entgegen der Kraft der Feder 7 zurückgedrückt. Weiters wird auch die Falle 3 über die Kulisse 28 und den Mitnahmezapfen 27 entgegen der Kraft der Feder 30 zurückgezogen.If the push rod 23 is displaced upward from this position by means of a lock cylinder or a pusher, not shown, first the back pressure securing bolts 24 reach the areas of the clearances 22 and then the bolt 4 is moved against the force of the spring via the slide 26 and its driving pin 25 7 pushed back. Furthermore, the case 3 is withdrawn via the gate 28 and the driving pin 27 against the force of the spring 30.

Beim Zurückschieben des Riegels 4 gleitet dieser unter den Auslöseschieber 14, bzw. dessen Haltevorsprung 18 durch, wonach dieser durch die Feder 29 in die Raste 20 des Schiebers gedrückt wird und so den Riegel 4 wieder in seiner zurückgezogenen Stellung blockiert.When pushing back the bolt 4, this slides under the trigger slide 14, and its retaining projection 18, after which it is pressed by the spring 29 into the catch 20 of the slider, thus blocking the latch 4 again in its retracted position.
