Definitions

  • the invention relates to a buckle for a seat belt, consisting of a slide-in tongue with a locking recess and a lock with an insertion path for the slide-in tongue, which is limited at least on one side by guide devices and is open at its front end and contains an ejector spring, with a latch pivotably mounted in the lock , the pivot axis of which extends transversely to the direction of the insertion path and which forms a locking face which interacts with the locking recess of the insertion tongue and which can be moved into the insertion path from the side remote from the guide devices and is arranged such that in the locking position the ejector spring disengages the locking bar urges, and with a pivot lever for securing the bolt in the locking position, which is forced into the locking position by spring force and for opening the lock by actuating a guided approximately parallel to the insertion path and on the by the guide his remote side of the same arranged slide is removable therefrom.
  • the object of the invention is therefore to create a buckle of the type mentioned at the outset which can be opened more reliably, namely by means of forces to be exerted from the outside by means of the slide.
  • the solution according to the invention is that the bolt is provided on the side remote from the guide devices with a projection which cooperates with the slide to pivot the bolt out of the locked position when the slide is actuated.
  • the projection of the bolt and the slide which can be provided with a projection for this purpose, cooperate rigidly and relentlessly, at least in the last movement phase of the slide, so that the opening force exerted on the slide fully on the projection of the bolt is transmitted.
  • an elastic member may additionally or possibly also be provided on the projection of the bolt or on the slide, which causes an increasing opening force to be exerted on the bolt as the slide moves as the lock is opened. This results in a gentle opening force on the bolt, which makes the operation of the lock pleasant.
  • An elastic cooperation can be achieved particularly easily if the slide is provided with a projection which interacts directly and unrelentingly with the projection of the bolt first via an elastic part and finally with maximum compression of the elastic part.
  • the approach of the slide can e.g. are made of plastic and can have one or more arms as elastic members which engage transversely to their longitudinal direction with the projection of the bolt and thereby bend elastically.
  • the ledge of the bolt can consist of plastic. In addition to the elasticity, this material also has the advantage that it is easy and inexpensive to apply to the bar, e.g. by overmolding.
  • the projection can be provided near the pivot axis of the bolt. This has the advantage that the projection only makes very slight movements perpendicular to the direction of insertion and, to that extent, there is no significant friction between the slide or attachment of the slide on the one hand and the projection on the other.
  • the projection can e.g. be formed in one piece with a plastic coating of the bolt in the region of the pivot axis, which enables simple manufacture. This plastic coating can extend into the bearing of the pivot axis, so that there the bearing projections of the bolt and the cutouts of the bearing housing used for their storage are at least partially separated from one another, so that rattling noises are prevented or reduced and the life of the lock is extended.
  • the lock body consists of a flat bottom 1 and two side walls 2, which stand vertically upright from its parallel edges and are rigidly connected to the bottom. It has a U-shaped cross section. Its bottom 1 contains a bore 3 for fastening an anchoring part.
  • the bottom 1 and the parts of the side walls 2 adjoining it form guide devices for the insertion tongue by forming the lower and lateral delimitation of the insertion path of the insertion tongue 4, the front part 5 having approximately the width of the insertion path between the side walls 2. It has a locking recess 6, which forms a locking surface at 7. At its rear end, it is provided in a known manner with a recess 8 for receiving a belt loop. At the top, the insertion path is limited by projections 9 rigidly connected to the lock body.
  • the known casing of the lock body by a plastic housing is not shown for the sake of simplicity. All directional information such as “top”, “right”, “clockwise” etc. refer to the representation in Fig. 1 and 2; "front” and “back” on the direction of the insertion movement.
  • the lock contains an ejector plate 10 in the insertion path, which is movably guided in the direction of the insertion path in a manner not shown and is loaded against the insertion direction by a spring 11 which is guided in bottom slots.
  • a spring 11 which is guided in bottom slots.
  • the locking plate consists of a rear cross part 15 connecting the projections 13 and a plate part 16 leading therefrom, which carries a downwardly projecting locking part 17 at the front, which forms a locking end 18 pointing towards the rear.
  • the latch part 17 protrudes slightly towards the front from the plate part 16, so that a free surface 19 is formed on its upper side, which is limited at the front by its front edge. In the locked state (FIG. 1), this surface lies in the upper boundary plane of the insertion path or a little above it.
  • the locking plate 14 has at its rear end at least one projection 20 which projects downward near the axis of rotation of the locking plate defined by the front end of the cutouts 12 and limits the insertion path to the rear. Together with the ejector plate 10, it serves to positively lock the insertion tongue. This moves namely the ejector plate 10 when inserted backwards against the pressure of the ejector spring 11, the ejector plate 10 being so long that it just abuts the projection 20, thereby causing a counterclockwise rotation of the bolt when the locking surface 7 of the insertion tongue 4 has just passed under the locking face 18 of the locking part 17.
  • the locking face 18 of the locking part 17 is approximately perpendicular to the direction of the insertion path and at an obtuse angle to the connecting line with the locking axis. If a force is exerted to the left in the direction of the insertion path, for example by a belt force acting on the insertion tongue or by the ejector spring 11, a torque is therefore exerted on the bolt which is dependent on the force acting in the insertion path and the distance of the Insertion path from the bolt axis of rotation is formed as a lever arm. This torque tries to turn the bolt clockwise, to lift the bolt part 17 out of the bolt recess of the insertion tongue and thus to release the lock. This is prevented by the pivot lever 21 in the locked state.
  • This pivot lever 21 is located above the upward-facing surface 19 of the locking part 17. It is designed as a plate extending transversely in the lock body, the outline of which can be seen in Fig. 4 on the left, while it has partially broken away on the right to allow a view of the Release the locking plate.
  • the pivoting lever is mounted with its lateral projections 22 in cutouts 24 in the side walls 2, so that there is an axis of rotation in the region 25 (FIG. 1) which is parallel to the axis of rotation of the bolt 13-17. It can therefore be pivoted at least between the two end positions, which are shown in FIGS. 1 and 2.
  • pivot lever 21 For pivoting serves on the one hand a spring 26 which tries to pivot it counterclockwise, and on the other hand the slide 27, which is guided parallel to the insertion path in a manner not shown in the lock body and pushes against movement to the right against the upper end of the pivot lever and the pivot lever thereby rotating clockwise.
  • the pivot lever 21 is held in the secured position by the spring 26 and by self-locking.
  • the spring 26 is advantageously designed so that it is on the one hand on the lower part of the pivot lever and on the other hand on the Slider 27 supports. Both parts are thereby pushed into their normal position with double effect. It can of course be carried out differently than it is shown in the drawing.
  • the pivot lever is made narrower towards the center. Its upper part 40 (Fig. 4) forms a stop cooperating with the slide. To the right and left of it (Fig. 4) he leaves space for the passage of parts 41 of the slide 27, which unite behind (right of it in Fig. 1) to form an extension 30 of the slide.
  • the projection 30 carries a pin 42 of certain length which projects to the rear (on the right in the illustration) and on which a helical spring 43 is guided which is longer than the pin. From the top of the bolt 14 a projection 32 protrudes near the pivot axis up to behind the pin 42 and the spring 43, the length of which is dimensioned such that it does not reach the projection 32 in the locked state of the lock and thus does not exert any force on it.
  • a plastic surface 34 is provided, which projects behind the bearing projections 13 of the bolt into the bearing cutouts 24 and therefore prevents direct, metallic contact of the bolt projections with the cutouts and prevents rattling noises.
  • the ejector plate 10 In the released state of the lock (Fig. 2), the ejector plate 10 is in the insertion path under the bolt part 17 of the bolt, so that it cannot block the insertion path. It is therefore possible to move the insertion tongue 5 to the right into the insertion path, the ejector plate 10 also being pushed to the right. When the ejector plate 10 reaches the projections 20, the locking recess 6 of the insertion tongue 4 is located below the locking part 17. When the movement continues, the bolt is pivoted counterclockwise by the impact of the ejector plate 10 onto the projection 20, so that the locking part 17 is inserted into the locking recess 6 must penetrate.
  • the lower end of the pivoting lever 21 bears against the forward-facing forehead of the locking part 17 due to the spring force 26.
  • the aforementioned forehead slides under the pivot bolt so that it can rotate counterclockwise under the action of the spring 26 until it abuts the rear boundary 28 of the bearing cutouts 24 (FIG . 1).
  • the forehead 29, which points downward, of the pivoting lever 21 is located directly above the upwardly facing surface 19 of the locking part. In this position, in which the pivot bolt is held by the spring 26, it secures the bolt 13-17 in the locking position.
  • the locking surface 7 of the insertion tongue 4 exerts a force on the locking face 18 of the locking part 17 in the direction of the insertion path, the line of action of which in the insertion path and therefore at a certain distance below the pivot axis of the locking bolt 13-17 defined by the cutouts 13 runs. If the bolt were not secured in its position by the pivot lever 21, a torque would therefore be generated on the bolt 13-17 in a clockwise direction, which would force it out of the locking position into the open position.
  • the geometric ratios are chosen so that this torque would normally be sufficient to open the bolt under the action of the ejector spring 11 alone.
  • FIG. 5 and 6 show another embodiment of those parts of the illustrated lock which transmit the opening force from the slide extension 30 to the locking projection.
  • the rear surface of which is designated 44 two arms 31 are arranged which, for example, are made in one piece with the slide from an elastic plastic (for example polyamide). They end in thickened heads 45 which lie between the locking projection 32 and the rear surface 44 of the slide attachment. They run across the direction of movement of the slide.
  • the heads 45 When this is pushed into the lock body to open the lock (FIG. 3), the heads 45 first come into contact with the locking projection 32 and urge it on further Movement of the slide with resilient deformation of the arms 31 to the right, whereby an opening force is exerted on the bolt. If the slide is moved further to the right, the state according to FIG. 6 finally occurs, in which the projection 30 exerts its force directly via the heads 45 on the locking projection without the intermediary of the resilient arms 31.

Description

Die Erfindung betrifft eine Schnalle für einen Sicherheitsgurt, bestehend aus einer Einschubzunge mit einer Verriegelungsausnehmung und einem Schloß mit einem mindestens auf einer Seite von Führungseinrichtungen begrenzten, an seinem vorderen Ende offenen, eine Auswerferfeder enthaltenden Einschubweg für die Einschubzunge, mit einem im Schloß schwenkbar gelagerten Riegel, dessen Schwenkachse quer zur Richtung des Einschubwegs verläuft und der eine mit der Verriegelungsausnehmung der Einschubzunge zusammenwirkende Riegelstirn bildet, die von der von den Führungseinrichtungen abgelegenen Seite her in den Einschubweg bewegbar ist und so angeordnet ist, daß in der Verriegelungsstellung die Auswerferfeder den Riegel außer Eingriff drängt, und mit einem Schwenkhebel zum Sichern des Riegels in der Verriegelungsstellung, der durch Federkraft in die Sicherungsstellung gedrängt und zum Öffnen des Schlosses durch Betätigung eines etwa parallel zum Einschubweg geführten und auf der von den Führungseinrichtungen abgelegenen Seite desselben angeordneten Schieber daraus entfernbar ist.The invention relates to a buckle for a seat belt, consisting of a slide-in tongue with a locking recess and a lock with an insertion path for the slide-in tongue, which is limited at least on one side by guide devices and is open at its front end and contains an ejector spring, with a latch pivotably mounted in the lock , the pivot axis of which extends transversely to the direction of the insertion path and which forms a locking face which interacts with the locking recess of the insertion tongue and which can be moved into the insertion path from the side remote from the guide devices and is arranged such that in the locking position the ejector spring disengages the locking bar urges, and with a pivot lever for securing the bolt in the locking position, which is forced into the locking position by spring force and for opening the lock by actuating a guided approximately parallel to the insertion path and on the by the guide his remote side of the same arranged slide is removable therefrom.

Bei einer Schnalle dieser Art (ältere europäische Patentanmeldung 80107136.6 der Anmelderin, gemaß Art. 54(3) EPÜ) wird durch den Schwenkhebel das Schloß in der verriegelten Stellung gehalten. Obwohl die Auswerferfeder und auch eine ggf. auf den Sicherheitsgurt wirkende Zugkraft den Riegel außer Eingriff zu drängen sucht, kann sich das Schloß nicht öffnen, weil der Schwenkhebel den Riegel in der Verriegelungsstellung festhält. Drückt man jedoch auf den Schieber, so wird der Schwenkhebel aus seiner Verriegelungsstellung entfernt, so daß der Riegel durch die Kraft der Auswerferfeder verschwenkt und die Einschubzungegelöst wird. Es kann unter ungünstigen Verhältnissen vorkommen, daß die Kraft der Auswerferfeder zum Verschwenken des Riegels nicht ausreicht, beispielsweise bei Verschmutzung des Schlosses oder nach Verformung bei einem Unfall.In the case of a buckle of this type (earlier European patent application 80107136.6 by the applicant, in accordance with Art. 54 (3) EPC), the lock is held in the locked position by the pivot lever. Although the ejector spring and any tensile force acting on the seat belt may be trying to force the bolt out of engagement, the lock cannot open because the pivot lever holds the bolt in the locked position. However, if one presses on the slide, the pivot lever is removed from its locking position, so that the bolt is pivoted by the force of the ejector spring and the insertion is released. Under unfavorable conditions it can happen that the force of the ejector spring is not sufficient to pivot the bolt, for example if the lock is dirty or after deformation in an accident.

Die Aufgabe der Erfindung besteht daher darin, eine Schnalle der eingangs genannten Art zu schaffen, die zuverlässiger zu öffnen ist, nämlich durch von außen mittels des Schiebers auszu- übende Kräfte.The object of the invention is therefore to create a buckle of the type mentioned at the outset which can be opened more reliably, namely by means of forces to be exerted from the outside by means of the slide.

Die erfindungsgemäße Lösung besteht darin, daß der Riegel auf der von den Führungseinrichtungen abgelegenen Seite mit einem Vorsprung versehen ist, der bei Betätigung des Schiebers mit diesem zum Verschwenken des Riegels aus der Verriegelungsstellung zusammenwirkt.The solution according to the invention is that the bolt is provided on the side remote from the guide devices with a projection which cooperates with the slide to pivot the bolt out of the locked position when the slide is actuated.

Es ist zweckmäßig, wenn der Vorsprung des Riegels und der Schieber, der zu diesem Zweck mit einem Vorsprung versehen sein kann, zumindest in der letzten Bewegungsphase des Schiebers starr und unnachgiebig zusammenwirken, damit die .auf den Schieber ausgeübte Öffnungskraft voll auf den Vorsprung des Riegels übertragen wird. Jedoch kann zusätzlich oder ggf. auch statt dessen ein elastisches Glied an dem Vorsprung des Riegels oder an dem Schieber vorgesehen sein, welches bewirkt, daß mit fortschreitender Verschiebung des Schiebers beim Öffnen des Schlosses eine zunehmende Öffnungskraft auf den Riegel ausgeübt wird. Dies ergibt eine sanfte Öffnungskraft auf den Riegel, welche die Bedienung des Schlosses angenehm macht.It is expedient if the projection of the bolt and the slide, which can be provided with a projection for this purpose, cooperate rigidly and relentlessly, at least in the last movement phase of the slide, so that the opening force exerted on the slide fully on the projection of the bolt is transmitted. However, an elastic member may additionally or possibly also be provided on the projection of the bolt or on the slide, which causes an increasing opening force to be exerted on the bolt as the slide moves as the lock is opened. This results in a gentle opening force on the bolt, which makes the operation of the lock pleasant.

Beginnt man den Schieber hineinzuschieben, so ist der Riegel zunächst noch durch den Schwenkhebel blockiert. Je weiter man den Schieber hineindrückt, eine um so größere Kraft wird dabei auf den Riegel aufgrund der elastischen Kopplung zwischen Schieber und Riegel ausgeübt. Ist der Schieber so weit hineingedrückt, daß die Verriegelung durch den Schwenkhebel aufgehoben wird, so ist diese auf den Riegel wirkende Kraft des Schiebers inzwischen so stark angewachsen, daß die Öffnungsbewegung des Riegels wirksam unterstützt wird. Auf diese Weise wird der Riegel auch dann aus seiner Verriegelungsstellung bewegt, wenn aus irgendwelchen Gründen die selbsttätige Entriegelung aufgrund der inneren Kräfte beziehungsweise der Zugkraft des Gurtes versagt.If you start to push the slide in, the bolt is initially blocked by the swivel lever. The further you push in the slide, the greater the force exerted on the bolt due to the elastic coupling between the slide and bolt. If the slide is pushed in so far that the locking is released by the pivot lever, this force acting on the bolt of the slide has meanwhile grown so much that the opening movement of the bolt is effectively supported. In this way, the bolt is also moved out of its locking position if for some reason the automatic unlocking fails due to the internal forces or the tensile force of the belt.

Ein elastisches Zusammenwirken läßt sich besonders einfach erreichen, wenn der Schieber mit einem Ansatz versehen ist, der mit dem Vorsprung des Riegels zunächst über einen elastischen Teil und schließlich bei maximaler Zusammendrückung des elastischen Teils direkt und unnachgiebig zusammenwirkt. Der Ansatz des Schiebers kann z.B. aus Kunststoff bestehen und kann einen oder mehrere Arme als elastische Glieder aufweisen, die quer zu ihrer Längsrichtung mit dem Vorsprung des Riegels in Eingriff kommen und sich dabei elastisch verbiegen.An elastic cooperation can be achieved particularly easily if the slide is provided with a projection which interacts directly and unrelentingly with the projection of the bolt first via an elastic part and finally with maximum compression of the elastic part. The approach of the slide can e.g. are made of plastic and can have one or more arms as elastic members which engage transversely to their longitudinal direction with the projection of the bolt and thereby bend elastically.

Der Vorsprung des Riegels kann aus Kunststoff bestehen. Dieses Material hat neben der Elastizität auch den Vorteil, daß es leicht und kostengünstig auf dem Riegel aufzubringen ist, z.B. durch Umspritzen.The ledge of the bolt can consist of plastic. In addition to the elasticity, this material also has the advantage that it is easy and inexpensive to apply to the bar, e.g. by overmolding.

Der Vorsprung kann nahe der Schwenkachse des Riegels vorgesehen sein. Dies hat den Vorteil, daß der Vorsprung nur sehr geringe Bewegungen senkrecht zur Einschubrichtung ausführt und insofern keine wesentliche Reibung zwischen Schieber bzw. Ansatz des Schiebers einerseits und Vorsprung andererseits auftritt. Der Vorsprung kann z.B. einstückig mit einem Kunststoffüberzug des Riegels im Bereich der Schwenkachse ausgebildet sein, was eine einfache Herstellung ermöglicht. Dieser Kunststoffüberzug kann sich bis in die Lagerung der Schwenkachse erstrecken, so daß dort die Lagervorsprünge des Riegels und die zu deren Lagerung dienenden Ausschnitte des Lagergehäuses wenigstens teilweise voneinander getrennt sind, so daß Klappergeräusche verhindert oder vermindert werden und die Lebensdauer des Schlosses verlängert wird.The projection can be provided near the pivot axis of the bolt. This has the advantage that the projection only makes very slight movements perpendicular to the direction of insertion and, to that extent, there is no significant friction between the slide or attachment of the slide on the one hand and the projection on the other. The projection can e.g. be formed in one piece with a plastic coating of the bolt in the region of the pivot axis, which enables simple manufacture. This plastic coating can extend into the bearing of the pivot axis, so that there the bearing projections of the bolt and the cutouts of the bearing housing used for their storage are at least partially separated from one another, so that rattling noises are prevented or reduced and the life of the lock is extended.

Die Erfindung wird im folgenden beispielsweise anhand der beigefügten Zeichnung beschrieben. Es zeigen:

  • Fig. 1, 2 und 3 Längsschnitte durch das Schloß in unterschiedlichen Funktionsstadien,
  • Fig. 4 eined Querschnitt im Bereich des Schwenkhebels und
  • Fig. 5 und 6 eine Draufsicht auf einen Teil der Schnalle in einer etwas anderen Ausführungsform.
The invention is described below, for example, with reference to the accompanying drawings. Show it:
  • 1, 2 and 3 longitudinal sections through the castle in different functional stages,
  • Fig. 4 a cross section in the region of the pivot lever and
  • 5 and 6 is a plan view of a part of the buckle in a slightly different embodiment.

Der Schloßkörper besteht aus einem ebenen Boden 1 und zwei von dessen parallelen Rändern lotrecht hochstehenden mit dem Boden starr verbundenen Seitenwänden 2. Er hat im Querschnitt U-förmige Gestalt. Sein Boden 1 enthält eine Bohrung 3 zur Befestigung eines Verankerungsteils.The lock body consists of a flat bottom 1 and two side walls 2, which stand vertically upright from its parallel edges and are rigidly connected to the bottom. It has a U-shaped cross section. Its bottom 1 contains a bore 3 for fastening an anchoring part.

Der Boden 1 und die an ihn angrenzenden Teile der Seitenwände 2 bilden Führungseinrichtungen für die Einschubzunge, indem sie die untere und seitliche Begrenzung des Einschubwegs der Einschubzunge 4 bilden, dem vorderer Teil 5 etwa die Breite des Einschubwegs zwischen den Seitenwänden 2 aufweist. Sie hat eine Verriegelungsausnehmung 6, die bei 7 eine Verriegelungsfläche bildet. An ihrem hinteren Ende ist sie in bekannter Weise mit einer Ausnehmung 8 zur Aufnahme einer Gurtschlaufe versehen. Nach oben hin ist der Einschubweg durch starr mit dem Schloßkörper verbundene Vorsprünge 9 begrenzt. Die bekannte Umkleidung des Schloßkörpers durch ein Kunststoffgehäuse ist der Einfachheit halber nicht dargestellt. Alle Richtungsangaben wie "oben", "rechts", "Uhrzeigersinn" etc. beziehen sich auf die Darstellung in Fig. 1 und 2; "vorn" und "hinten" auf die Richtung der Einschubbewegung.The bottom 1 and the parts of the side walls 2 adjoining it form guide devices for the insertion tongue by forming the lower and lateral delimitation of the insertion path of the insertion tongue 4, the front part 5 having approximately the width of the insertion path between the side walls 2. It has a locking recess 6, which forms a locking surface at 7. At its rear end, it is provided in a known manner with a recess 8 for receiving a belt loop. At the top, the insertion path is limited by projections 9 rigidly connected to the lock body. The known casing of the lock body by a plastic housing is not shown for the sake of simplicity. All directional information such as "top", "right", "clockwise" etc. refer to the representation in Fig. 1 and 2; "front" and "back" on the direction of the insertion movement.

Das Schloß enthält in Einschubweg eine Auswerferplatte 10, die darin auf nicht gezeigte Weise in Richtung des Einschubweges beweglich geführt ist und entgegen der Einschubrichtung durch eine Feder 11 beansprucht ist, die in Bodenschlitzen geführt ist. In Figuren 1 bis 3 ist daher der Einschubweg durch die Oberseite des Bodens 1 und durch die Lage der Einschubzunge 4 und der Auswerferplatte 10 sowie durch die Vorsprünge 9 erkennbar.The lock contains an ejector plate 10 in the insertion path, which is movably guided in the direction of the insertion path in a manner not shown and is loaded against the insertion direction by a spring 11 which is guided in bottom slots. In Figures 1 to 3, the insertion path through the top of the bottom 1 and through the position of the insertion tongue 4 and the ejector plate 10 and through the projections 9 can be seen.

In der hinteren (in der Zeichnung also rechten) Hälfte des Schloßkörpers befindet sich in beiden Seitenwänden 2 an übereinstimmender Stelle ein Ausschnitt 12 zur Aufnahme seitlicher Vorsprünge 13 einer Riegelplatte 14. Zwischen den Ausschnitten 12 und den zugehörigen Vorsprüngen 13 ist so viel Spiel vorhanden, daß die Riegelplatte 14 um einen kleinen Winkel um eine quer zur Einschubrichtung und parallel zum Boden 1 liegende Achse schwenkbar ist. Die beiden im Betrieb der Vorrichtung praktisch auftretenden Endstellungen sind in Fig. 1 und 2 dargestellt. Die Riegelplatte besteht aus einem hinteren, die Vorsprünge 13 verbindenden Querteil 15 und einem davon nach vorn führenden Plattenteil 16, der vorne einen nach unten vorspringenden Riegelteil 17 trägt, der eine nach hinten weisende Riegelstirn 18 bildet. Der Riegelteil 17 ragt nach vorne gegenüber dem Plattenteil 16 ein wenig vor, so daß sich auf seiner Oberseite eine freie Fläche 19 bildet, die nach vorne durch seine Vorderkante begrenzt ist. Im Verriegelungszustand (Fig. 1) liegt diese Fläche in der oberen Begrenzungsebene des Einschubweges oder ein wenig darüber.In the rear (right in the drawing) half of the lock body there is a cutout 12 in both side walls 2 at a corresponding location for receiving lateral projections 13 of a locking plate 14. There is so much play between the cutouts 12 and the associated projections 13 that the locking plate 14 can be pivoted through a small angle about an axis lying transversely to the direction of insertion and parallel to the floor 1. The two end positions practically occurring during the operation of the device are shown in FIGS. 1 and 2. The locking plate consists of a rear cross part 15 connecting the projections 13 and a plate part 16 leading therefrom, which carries a downwardly projecting locking part 17 at the front, which forms a locking end 18 pointing towards the rear. The latch part 17 protrudes slightly towards the front from the plate part 16, so that a free surface 19 is formed on its upper side, which is limited at the front by its front edge. In the locked state (FIG. 1), this surface lies in the upper boundary plane of the insertion path or a little above it.

Die Riegelplatte 14 weist an ihrem hinteren Ende mindestens einen Vorsprung 20 auf, der nahe der durch das vordere Ende der Ausschnitte 12 festgelegten Drehachse der Riegelplatte nach unten ragt und den Einschubweg nach hinten begrenzt. Er dient zusammen mit der Auswerferplatte 10 der Zwangsverriegelung der Einschubzunge. Diese bewegt nämlich die Auswerferplatte 10 beim Einschieben nach hinten entgegen dem Druck der Auswerferfeder 11, wobei die Auswerferplatte 10 so lang ausgeführt ist, daß sie gerade gegen den Vorsprung 20 stößt, dadurch eine Linksdrehung des Riegels im Gegenuhrzeigersinn veranlassend, wenn die Verriegelungsfläche 7 der Einschubzunge 4 soeben unter der Riegelstirn 18 des Riegelteils 17 hindurchgegangen ist.The locking plate 14 has at its rear end at least one projection 20 which projects downward near the axis of rotation of the locking plate defined by the front end of the cutouts 12 and limits the insertion path to the rear. Together with the ejector plate 10, it serves to positively lock the insertion tongue. This moves namely the ejector plate 10 when inserted backwards against the pressure of the ejector spring 11, the ejector plate 10 being so long that it just abuts the projection 20, thereby causing a counterclockwise rotation of the bolt when the locking surface 7 of the insertion tongue 4 has just passed under the locking face 18 of the locking part 17.

Die Riegelstirn 18 des Riegelteils 17 steht in Verriegelungszustand etwa senkrecht zu der Richtung des Einschubwegs und in einem stumpfen Winkel zur Verbingungslinie mit der Riegelachse. Wenn auf die Riegeistirn 18 eine Kraft nach links in Richtung des Einschubwegs ausgeübt wird, beispielsweise durch eine auf die Einschubzunge wirkende Gurtkraft oder durch die Auswerferfeder 11, wird daher ein Drehmoment auf den Riegel ausgeübt, das von der im Einschubweg wirkenden Kraft und dem Abstand des Einschubwegs von der Riegeldrehachse als Hebelarm gebildet ist. Dieses Drehmoment sucht den Riegel im Uhrzeigersinn zu drehen, den Riegelteil 17 aus der Riegelausnehmung der Einschubzunge zu heben und somit die Verriegelung zu lösen. Dies wird im Verriegelungszustand durch den Schwenkhebel 21 verhindert. Dieser Schwenkhebel 21 befindet sich oberhalb der nach oben weisenden Fläche 19 des Verriegelungsteils 17. Er ist als eine sich quer im Schloßkörper erstreckende Platte ausgebildet, deren Umriß man in Fig. 4 links erkennt, während sie rechts teilweise weggebrochen ist, um den Blick auf die Riegelplatte freizugeben. Der Schwenkhebel ist mit seinen seitlichen Vorsprüngen 22 in Ausschnitten 24 der Seitenwände 2 gelagert, so daß sich im Bereich 25 (Fig. 1) eine Drehachse ergibt, die parallel zur Drehachse des Riegels 13-17 ist. Er läßt sich daher verschwenken mindestens zwischen den beiden Endstellungen, die in Fig. 1 und 2 dargestellt sind. Zur Verschwenkung dient einerseits eine Feder 26, die ihn im Gegenuhrzeigersinn zu schwenken versucht, und andererseits der Schieber 27, der parallel zum Einschubweg auf nicht gezeigte Weise im Schloßkörper beweglich geführt ist und bei Bewegung nach rechts gegen das obere Ende des Schwenkhebels stößt und den Schwenkhebel dadurch im Uhrzeigersinn dreht. Der Schwenkhebel 21 wird in der Sicherungsstellung durch die Feder 26 und durch Selbsthemmung gehalten.In the locked state, the locking face 18 of the locking part 17 is approximately perpendicular to the direction of the insertion path and at an obtuse angle to the connecting line with the locking axis. If a force is exerted to the left in the direction of the insertion path, for example by a belt force acting on the insertion tongue or by the ejector spring 11, a torque is therefore exerted on the bolt which is dependent on the force acting in the insertion path and the distance of the Insertion path from the bolt axis of rotation is formed as a lever arm. This torque tries to turn the bolt clockwise, to lift the bolt part 17 out of the bolt recess of the insertion tongue and thus to release the lock. This is prevented by the pivot lever 21 in the locked state. This pivot lever 21 is located above the upward-facing surface 19 of the locking part 17. It is designed as a plate extending transversely in the lock body, the outline of which can be seen in Fig. 4 on the left, while it has partially broken away on the right to allow a view of the Release the locking plate. The pivoting lever is mounted with its lateral projections 22 in cutouts 24 in the side walls 2, so that there is an axis of rotation in the region 25 (FIG. 1) which is parallel to the axis of rotation of the bolt 13-17. It can therefore be pivoted at least between the two end positions, which are shown in FIGS. 1 and 2. For pivoting serves on the one hand a spring 26 which tries to pivot it counterclockwise, and on the other hand the slide 27, which is guided parallel to the insertion path in a manner not shown in the lock body and pushes against movement to the right against the upper end of the pivot lever and the pivot lever thereby rotating clockwise. The pivot lever 21 is held in the secured position by the spring 26 and by self-locking.

Die Feder 26 ist zweckmäßigerweise so ausgeführt, daß sie sich einerseits an dem unteren Teil des Schwenkhebels und andererseits an dem Schieber 27 abstützt. Beide Teile werden dadurch mit doppelter Wirkung in ihre Normalstellung gedrängt. Sie kann selbstverständlich anders ausgeführt sein, als es in der Zeichnung dargestellt ist.The spring 26 is advantageously designed so that it is on the one hand on the lower part of the pivot lever and on the other hand on the Slider 27 supports. Both parts are thereby pushed into their normal position with double effect. It can of course be carried out differently than it is shown in the drawing.

Oberhalb des zwischen den Vorsprüngen 22 liegenden Bereichs ist der Schwenkhebel zur Mitte hin schmaler ausgeführt. Sein oberer Teil 40 (Fig. 4) bildet einen mit dem Schieber zusammenwirkenden Anschlag. Rechts und links davon (Fig. 4) läßt er Raum für den Durchtritt von Teilen 41 des Schiebers 27, die sich dahinter (rechts davon in Fig. 1) zu einem Ansatz 30 des Schiebers vereinigen.Above the area between the projections 22, the pivot lever is made narrower towards the center. Its upper part 40 (Fig. 4) forms a stop cooperating with the slide. To the right and left of it (Fig. 4) he leaves space for the passage of parts 41 of the slide 27, which unite behind (right of it in Fig. 1) to form an extension 30 of the slide.

In der Ausführungsform gemäß Fig. 1 bis 3 trägt der Ansatz 30 einen nach hinten (rechts in der Darstellung) ragenden Stift 42 bestimmter Länge, auf dem eine Schraubenfeder 43 geführt ist, die länger als der Stift ist. Von der Oberseite des Riegels 14 ragt nahe dessen Schwenkachse ein Vorsprung 32 hoch bis hinter den Stift 42 und die Feder 43, deren Länge so bemessen ist, daß sie im Verriegelungszustand des Schlosses den Vorsprung 32 nicht erreicht und somit keine Kraft auf ihn ausübt.In the embodiment according to FIGS. 1 to 3, the projection 30 carries a pin 42 of certain length which projects to the rear (on the right in the illustration) and on which a helical spring 43 is guided which is longer than the pin. From the top of the bolt 14 a projection 32 protrudes near the pivot axis up to behind the pin 42 and the spring 43, the length of which is dimensioned such that it does not reach the projection 32 in the locked state of the lock and thus does not exert any force on it.

An der Rückseite des Riegels ist eine Kunststofffläche 34 vorgesehen, die hinter den Lagervorsprüngen 13 des Riegels in die Lagerausschnitte 24 ragt und daher einen unmittelbaren, metallischen Kontakt der Riegelvorsprünge mit den Ausschnitten verhindert und Klappergeräusche vermeidet.On the back of the bolt, a plastic surface 34 is provided, which projects behind the bearing projections 13 of the bolt into the bearing cutouts 24 and therefore prevents direct, metallic contact of the bolt projections with the cutouts and prevents rattling noises.

Die erläuterte Anordnung ergibt folgende Funktionsweise.The arrangement explained results in the following mode of operation.

Im gelösten Zustand des Schlosses (Fig. 2) befindet sich die Auswerferplatte 10 im Einschubweg unter dem Riegelteil 17 des Riegels, so daß dieser den Einschubweg nicht versperren kann. Es ist daher möglich, die Einschubzunge 5 nach rechts in den Einschubweg zu bewegen, wobei die Auswerferplatte 10 ebenfalls nach rechts geschoben wird. Erreicht die Auswerferplatte 10 die Vorsprünge 20, so befindet sich die Verriegelungsausnehmung 6 der Einschubzunge 4 unterhalb des Riegelteils 17. Bei weiterer Bewegung wird der Riegel durch den Stoß der Auswerferplatte 10 auf den Vorsprung 20 im Gegenuhrzeigersinn geschwenkt, so daß der Riegelteil 17 in die Verriegelungsausnehmung 6 eindringen muß.In the released state of the lock (Fig. 2), the ejector plate 10 is in the insertion path under the bolt part 17 of the bolt, so that it cannot block the insertion path. It is therefore possible to move the insertion tongue 5 to the right into the insertion path, the ejector plate 10 also being pushed to the right. When the ejector plate 10 reaches the projections 20, the locking recess 6 of the insertion tongue 4 is located below the locking part 17. When the movement continues, the bolt is pivoted counterclockwise by the impact of the ejector plate 10 onto the projection 20, so that the locking part 17 is inserted into the locking recess 6 must penetrate.

Im gelösten Zustand des Schlosses liegt das untere Ende des Schwenkhebels 21 aufgrund der Federkraft 26 unter Vorspannung an der nach vorn weisenden Stirn des Riegelteils 17 an. In dem Augenblick, wo dieser sich in die Verriegelungsausnehmung der Einschubzunge senkt, gleitet die erwähnte Stirn unter den Schwenkriegel, so daß dieser sich unter der Wirkung der Feder 26 im Gegenuhrzeigersinn drehen kann, bis er an der hinteren Begrenzung 28 der Lagerausschnitte 24 anliegt (Fig. 1). Dabei befindet sich die nach unten weisende Stirn 29 des Schwenkhebels 21 unmittelbar oberhalb der nach oben weisenden Fläche 19 des Riegelteils. In dieser Stellung, in der der Schwenkriegel durch die Feder 26 gehalten wird, sichert er den Riegel 13-17 in der Verriegelungsstellung.In the released state of the lock, the lower end of the pivoting lever 21 bears against the forward-facing forehead of the locking part 17 due to the spring force 26. At the moment that it lowers into the locking recess of the insertion tongue, the aforementioned forehead slides under the pivot bolt so that it can rotate counterclockwise under the action of the spring 26 until it abuts the rear boundary 28 of the bearing cutouts 24 (FIG . 1). The forehead 29, which points downward, of the pivoting lever 21 is located directly above the upwardly facing surface 19 of the locking part. In this position, in which the pivot bolt is held by the spring 26, it secures the bolt 13-17 in the locking position.

Im Verriegelungszustand übt die Verriegelungsfläche 7 der Einschubzunge 4 auf die Riegelstirn 18 des Riegelteils 17 eine in Richtung des Einschubwegs nach links gerichtete Kraft aus, deren Wirkungslinie im Einschubweg und daher in einem gewissen Abstand unterhalb der durch die Ausschnitte 13 festgelegten Schwenkachse des Riegels 13-17 verläuft. Wäre der Riegel nicht durch den Schwenkhebel 21 in seiner Position gesichert, käme es daher zur Ausbildung eines Drehmoments auf den Riegel 13-17 im Uhrzeigersinn, der ihn aus der Verriegelungsstellung in die Öffnungsstellung drängen würde. Die geometrischen Verhältnisse sind so gewählt, daß dieses Drehmoment normalerweise schon allein unter der Wirkung der Auswerferfeder 11 zum Öffnen des Riegels ausreichen würde.In the locked state, the locking surface 7 of the insertion tongue 4 exerts a force on the locking face 18 of the locking part 17 in the direction of the insertion path, the line of action of which in the insertion path and therefore at a certain distance below the pivot axis of the locking bolt 13-17 defined by the cutouts 13 runs. If the bolt were not secured in its position by the pivot lever 21, a torque would therefore be generated on the bolt 13-17 in a clockwise direction, which would force it out of the locking position into the open position. The geometric ratios are chosen so that this torque would normally be sufficient to open the bolt under the action of the ejector spring 11 alone.

Wird nun zum Öffnen des Schlosses der Schieber 27 nach rechts bewegt (Fig. 3), so wird der Schwenkhebel 21 im Uhrzeigersinn gedreht, wodurch er beim Passieren der Vorderkante des Riegelteils 17 die Einwirkung auf die Sicherungsfläche 11 verliert. Der Riegel word dadurch frei und kann unter der Wirkung der auf ihn wirkenden Kräfte nach oben ausweichen und dadurch die Einschubzunge freigeben.If the slide 27 is now moved to the right to open the lock (FIG. 3), the pivot lever 21 is rotated clockwise, as a result of which it loses its action on the securing surface 11 when it passes the front edge of the locking part 17. The bolt is thus free and can move upwards under the action of the forces acting on it and thereby release the insertion tongue.

Diese Kräfte werden vornehmlich durch die Feder 43 bzw. den Stift 42 erzeugt. Beim Hereindrücken des Schiebers 27 kommt die Feder 43 des Schiebers gegen den Vorsprung 32 des Riegels und drückt diesen nach rechts. Dadurch wird ein Drehmoment im Uhrzeigersinn erzeugt, das den Riegel in die geöffnete Stellung verschwenkt. Dieses Drehmoment kann dadurch vergrößert werden, daß kräftiger auf den Schieber gedrückt wird, weil dann die Feder stärker komprimiert wird und eine entsprechend größere Kraft erzeugt wird. Sollte die Federkraft nicht ausreichen, so trifft schließlich der Stift 42 unmittelbar auf den Vorsprung 32, wie es in Fig. 3 angedeutet ist, so daß eine beliebig große Öffnungskraft auf den Riegel 14 ausgeübt werden kann. Auch unter ungünstigen Umständen erhält der Benutzer so eine große Sicherheit dafür, daß der Riegel tatsächlich in die geöffnete Stellung verschwenkt wird.These forces are primarily generated by the spring 43 or the pin 42. When pushing in the slide 27, the spring 43 of the slide comes against the projection 32 of the bolt and presses it to the right. This creates a clockwise torque that pivots the latch into the open position. This torque can be increased by pressing harder on the slide because the spring is then compressed more and a correspondingly greater force is generated. If the spring force is not sufficient, the pin 42 finally strikes the projection 32, as indicated in FIG. 3, so that an arbitrarily large opening force can be exerted on the bolt 14. Even under unfavorable circumstances, the user is given a great deal of certainty that the bolt is actually pivoted into the open position.

In Fig. 5 und 6 ist eine andere Ausführungsform derjenigen Teile des erläuterten Schlosses dargestellt, die die Öffnungskraft vom Schieberansatz 30 auf den Riegelvorsprung übertragen. Am hinteren Ende des Schieberansatzes 30, dessen Rückfläche mit 44 bezeichnet ist, sind zwei Arme 31 angeordnet, die beispielsweise einstückig mit dem Schieber aus einem elastischen Kunststoff (beispielsweise Polyamid) bestehen. Sie enden in verdickten Köpfen 45, die zwischen dem Riegelvorsprung 32 und der Rückfläche 44 des Schieberansatzes liegen. Sie verlaufen quer zur Bewegungsrichtung des Schiebers. Wenn dieser in den Schloßkörper zum Öffnen des Schlosses hineingeschoben wird (Fig. 3), kommen zunächst die Köpfe 45 mit dem Riegelvorsprung 32 in Berührung und drängen diesen bei weiterer Bewegung des Schiebers unter federnder Verformung der Arme 31 nach rechts, wodurch eine Öffnungskraft auf den Riegel ausgeübt wird. Wenn der Schieber weiter nach rechts bewegt wird, tritt schließlich der Zustand gemäß Fig. 6 ein, in welchem der Ansatz 30 ohne die Vermittlung der federnden Arme 31 seine Kraft unmittelbar über die Köpfe 45 auf den Riegelvorsprung ausübt.5 and 6 show another embodiment of those parts of the illustrated lock which transmit the opening force from the slide extension 30 to the locking projection. At the rear end of the slide extension 30, the rear surface of which is designated 44, two arms 31 are arranged which, for example, are made in one piece with the slide from an elastic plastic (for example polyamide). They end in thickened heads 45 which lie between the locking projection 32 and the rear surface 44 of the slide attachment. They run across the direction of movement of the slide. When this is pushed into the lock body to open the lock (FIG. 3), the heads 45 first come into contact with the locking projection 32 and urge it on further Movement of the slide with resilient deformation of the arms 31 to the right, whereby an opening force is exerted on the bolt. If the slide is moved further to the right, the state according to FIG. 6 finally occurs, in which the projection 30 exerts its force directly via the heads 45 on the locking projection without the intermediary of the resilient arms 31.
