Description

Die Erfindung betrifft eine Verschlußmechanik für Ordner mit einer, aus starren und beweglichen Dornen gebildeten Umlegeführung für gelochte Blätter, bei welcher die starren Dorne auf einer Bodenplatte fest verankert und die beweglichen Dorne an einem, auf der Bodenplatte schwenkbar gelagerten Schwenkbügel befestigt sind, der zum Öffnen und Schließen der Umlegeführung mit einem Betätigungselement eines Betätigungshebels im Eingriff steht, der an einer von der Bodenplatte nach oben abstehenden Lagerplatte, mittels zweier, zwischen Betätigungshebel und Lagerplatte ausgebildeter Führungen in der Ebene der Lagerplatte zwischen einer, die geschlossene Umlegeführung verriegelnden Verschlußstellung und einer Endstellung für die maximale Offenstellung der Umlegeführung bewegbar ist, wobei bei der einen Führung ein erster Führungsstift in eine Aussparung eingreift und in dieser entlang einer, vorzugsweise L-förmigen, Führungskurve zwischen einer, der Verschlußstellung des Betätigungshebels zugeordneten, ersten Rastposition und einer, der Endstellung des Betätigungshebels zugeordneten, zweiten Rastposition bewegbar ist, und wobei zumindest eine, die Umlegeführung in Öffnungsrichtung mittelbar beaufschlagende Feder vorgesehen ist.The invention relates to a locking mechanism for files with a, made of rigid and movable mandrels guide for perforated sheets, in which the rigid mandrels are firmly anchored on a base plate and the movable mandrels are attached to a pivotable on the base plate pivot bracket that can be opened and closing the diverter guide is in engagement with an actuating element of an actuating lever which, on a bearing plate projecting upward from the base plate, by means of two guides formed between the actuating lever and the bearing plate in the plane of the bearing plate between a locking position locking the closed diverter guide and an end position for the maximum open position of the guide is movable, with the one guide engaging a first guide pin in a recess and in this along a, preferably L-shaped, guide curve between a, the closed position of the Actuating lever associated with the first latching position and a second latching position assigned to the end position of the actuating lever is movable, and at least one spring is provided which acts indirectly on the guide in the opening direction.

Bei einer bekannten Ordnermechanik dieser Art (CH-PS 26 583) greift der Betätigungshebel mit einem Zapfen, der zur Steuerung der Hebelbewegung in einem zur Bodenplatte senkrechten Schlitz der Lagerplatte geführt ist, direkt am federbelasteten Schwenkbügel an und besitzt einen Winkelschlitz, in dem ein an der Lagerplatte fixierter Führungsstift eingreift, der, bei in der Verschlußstellung auf der Bodenplatte aufliegendem Betätigungshebel, an einem Ende des Winkelschlitzes anliegt und der, bei in der Offenstellung der Umlegeführung nach oben über die Dornenden vorstehendem Betätigungshebel, am anderen Ende des Winkelschlitzes anliegt. Bei dieser bekannten Ordnermechanik ist ein Umlegen der gelochten Blätter von den festen Dornen auf die beweglichen Dorne der Umlegeführung bei offener Umlegeführung nicht möglich. Dazu muß die Mechanik jedesmal zuerst geschlossen werden.In a known folder mechanism of this type (CH-PS 26 583) the actuating lever engages with a pin which is guided to control the lever movement in a slot of the bearing plate perpendicular to the base plate, directly on the spring-loaded swivel bracket and has an angular slot in which one the bearing plate fixed guide pin engages which, when the operating lever rests on the base plate in the closed position, rests against one end of the angular slot and which, when the guide is in the open position upwards over the mandrel ends of the above actuating lever, at the other end of the angular slot. With this known folder mechanism, it is not possible to fold the perforated sheets from the fixed mandrels to the movable mandrels of the guide when the guide is open. To do this, the mechanics must always be closed first.

Um ein Umlegen der gelochten Blätter bei offener Umlegeführung durch den an der Lagerplatte um eine ortsfeste Achse schwenkbaren Betätigungshebel nicht zu behindern, ist es aus der EP-A1-0 207 059 bekannt, den Schwenkbereich des federbelasteten Schwenkbügels mit den daran befestigten beweglichen Dornen gegenüber dem Schwenkbereich des Betätigungshebels so weit zu vergrößern, daß der Betätigungshebel bei offener Umlegeführung zwischen den Enden der festen und der beweglichen Dorne hindurch in eine zusätzliche Schwenkstellung weitergeschwenkt werden kann, in der er nach ca. 180° Schwenkwinkel seine 180° Endstellung erreicht und mit seiner Handhabe am Rücken des Ordners anliegt.In order not to hinder a folding of the perforated sheets when the guide is open due to the actuating lever which can be pivoted on the bearing plate about a fixed axis, it is known from EP-A1-0 207 059 that the pivoting range of the spring-loaded pivoting bracket with the movable spikes is opposite the To enlarge the swivel range of the operating lever so that the operating lever can be pivoted further between the ends of the fixed and the movable mandrels in an additional swivel position in which it reaches its 180 ° end position after about 180 ° swivel angle and with its handle against the back of the folder.

Diese bekannte Mechanik hat drei Hebelstellungen, nämlich eine Verschluß-Stellung, eine Endstellung und eine 180°-Endstellung. Sie bietet die Möglichkeit, den Betätigungshebel zum leichteren Umlegen der gelochten Blätter bei offener Umlegeführung über die übliche Endstellung hinaus bis in seine 180°-Endstellung zu bewegen, jedoch ist der dazu erforderliche Schwenkweg von einer Position des Betätigungshebels, in der eine Entnahme der gelochten Blätter aus der offenen Umlegeführung bereits möglich ist, bis in die 180°-Endstellung mindestens so groß, wie der Schwenkweg zurück in die Verschlußstellung, in der das Umlegen der gelochten Blätter zufolge der geschlossenen Umlegeführung noch wesentlich einfacher ist. Ein weiterer Nachteil besteht darin, daß der Betätigungsbügel in seiner 180°-Endlage nur schwer zu erfassen ist, da er mit seiner Handhabe auf der vom Benützer abgewandten Seite am Rücken des Ordners aufliegt.This known mechanism has three lever positions, namely a closed position, an end position and a 180 ° end position. It offers the possibility of moving the actuating lever to make it easier to fold the perforated sheets over the usual end position with the open guide, up to its 180 ° end position, but the required swivel path is from a position of the actuating lever in which the perforated sheets can be removed from the open diverter is already possible, up to the 180 ° end position at least as large as the swivel path back to the closed position, in which folding the perforated sheets is even easier due to the closed diverter. Another disadvantage is that the operating bracket in its 180 ° end position is difficult to grasp, since it lies on the back of the folder on the side facing away from the user.

Aufgabe der Erfindung ist es, eine Verschlußmechanik der eingangs genannten Art anzugeben, bei der das Öffnen der Umlegeführung durch leichtes Anheben des Griffendes des Betätigungshebels bewerkstelligt wird, welcher dabei automatisch in eine Endstellung bewegt wird, in der er ein Umlegen der gelochten Blätter nicht behindert und bei der das Schließen und Verriegeln der Umlegeführung durch leichtes Niederdrücken des Griffendes des Betätigungshebels erfolgt.The object of the invention is to provide a locking mechanism of the type mentioned, in which the opening of the diverter by slightly lifting the handle end of the operating lever is accomplished, which is automatically moved into an end position, in which it does not hinder a folding of the perforated sheets and in which the closing and locking of the guide is done by gently depressing the handle end of the operating lever.

Dies wird erfindungsgemäß dadurch erreicht, daß die zweite Führung eine, im Abstand von der Bodenplatte liegende, zur Bodenplatte im wesentlichen parallele Lage des Betätigungshebels für die Verschlußstellung definiert, in der unter dem Griffende genügend Freiraum für das Untergreifen des Griffendes bleibt und in der, der erste Führungsstift in der ersten Rastposition angeordnet ist, daß die zweite Führung eine der Verschlußstellung vorgeschaltete Verrastungsstellung des Betätigungshebels definiert, in der er der Bodenplatte benachbart angeordnet ist und aus der er um den, in der ersten Rastposition befindlichen ersten Führungsstift in die Verschlußstellung frei nach oben verschwenkbar ist, und daß die zweite Führung eine obere Endlage des Betätigungshebels als dessen Endstellung definiert, in welcher der Betätigungshebel, bei in der zweiten Rastposition befindlichem Führungsstift der ersten Führung, unterhalb der, durch die Dornenden der offenen Umlegeführung definierten Ebene bleibt.This is achieved according to the invention in that the second guide defines a position of the actuating lever for the closed position, which is at a distance from the base plate and is substantially parallel to the base plate, in which there is sufficient space under the handle end for reaching under the handle end and in which the first guide pin is arranged in the first latching position, so that the second guide defines a latching position of the actuating lever upstream of the closed position, in which it is arranged adjacent to the base plate and from which it moves freely upwards around the first guide pin located in the first latched position into the closed position is pivotable, and that the second guide defines an upper end position of the actuating lever as its end position, in which the actuating lever, when the guide pin of the first guide is in the second latching position, below that, through the mandrel ends of the open guide guide de level remains.

Durch die erfindungsgemäße Ausbildung wird der, für das Untergreifen des Griffendes des Betätigungshebels notwendige Freiraum beim Schließen der Umlegeführung als zusätzlicher Schwenkbereich für den Betätigungshebel und somit zur Verringerung des für das Schließen notwendigen Kraftaufwandes nutzbar gemacht. Zum Schließen und Verriegeln der Umlegeführung braucht der Betätigungshebel nur mehr zum Ordnerrücken gedrückt zu werden, bis das Griffende des Betätigungshebels am Ordnerrücken fast anliegt, worauf beim Loslassen des Betätigungshebels dieser in die Verschlußstellung verschwenkt, in der das Griffende wieder leicht zu untergreifen ist.The design according to the invention makes the space necessary for reaching under the handle end of the actuating lever when closing the diverter guide to be used as an additional pivoting range for the actuating lever and thus to reduce the force required for closing. To close and lock the diverter, the actuating lever only needs to be pushed towards the back of the folder until the handle end of the actuating lever is almost in contact with the back of the folder, whereupon when the actuating lever is released, it pivots into the closed position, in which the end of the handle can be easily gripped again.

Die Erfindung ermöglicht ein Umlegen der gelochten Blätter bei maximal offener Umlegeführung ohne durch den Betätigungshebel behindert zu sein. Der Betätigungshebel muß dazu keineswegs über jene Stellung hinausbewegt werden, in der die Umlegeführung bereits maximal offen ist.The invention enables the perforated sheets to be folded over with the guide being open at maximum, without being hindered by the actuating lever. The actuating lever does not have to be moved beyond that position in which the diversion is already open to the maximum.

Bei der vorliegenden Erfindung ergibt die Ausgestaltung der zweiten Führung eine Trennung der Schließbewegung des Betätigungshebels von dessen Öffnungsbewegung, d.h. die Öffnungsbewegung ist nicht mehr die genaue Umkehrung der Schließbewegung. Jeder Punkt des Betätigungshebels, ausgenommen die auf der Achse des ersten Führungsstiftes gelegenen Punkte, folgt beim Schließen der Umlegeführung einer anderen Kurvenbahn als beim Öffnen der Umlegeführung, wobei die jeweilige Form der Kurvenbahnen von der gegenseitigen Lage der beiden Führungen und deren Ausgestaltung bestimmt wird. Die zweite Führung kann erfindungsgemäß sowohl oberhalb als auch unterhalb der ersten Führung vorgesehen sein.In the present invention, the configuration of the second guide results in a separation of the closing movement of the operating lever from its opening movement, i.e. the opening movement is no longer the exact reversal of the closing movement. Each point of the actuating lever, with the exception of the points on the axis of the first guide pin, follows a different cam track when closing the bypass guide than when opening the bypass guide, the respective shape of the cam tracks being determined by the mutual position of the two guides and their design. According to the invention, the second guide can be provided both above and below the first guide.

Bei der erfindungsgemäßen Verschlußmechanik kennt der Betätigungshebel nur zwei Ruhestellungen, nämlich die Verschlußstellung bei geschlossener und verriegelter Umlegeführung und die Endstellung bei maximal offener Umlegeführung, und der Betätigungshebel bleibt mit seinem Griffende immer auf der dem Benützer zugewandten Seite.In the locking mechanism according to the invention, the operating lever knows only two rest positions, namely the locking position when the guide is closed and locked and the end position when the guide is open to the maximum, and the end of the handle always remains on the side facing the user.

Die erfindungsgemäße Verschlußmechanik kann in bekannter Weise mit einer, an der Bodenplatte abgestützten, am Schwenkbügel von unten angreifenden Feder versehen sein. Dabei wird in Ausgestaltung der Erfindung vorgeschlagen, daß das am Schwenkbügel angreifende, vorzugsweise als zylindrischer Vorsprung ausgebildete Betätigungselement, bei in der Verrastungsstellung befindlichem Betätigungshebel, gegenüber dem ersten Führungsstift zum Griffende des Betätigungshebels hin versetzt angeordnet ist.The locking mechanism according to the invention can be provided in a known manner with a spring which is supported on the base plate and acts on the swivel bracket from below. It is proposed in an embodiment of the invention that the actuating element acting on the swivel bracket, preferably in the form of a cylindrical projection, is arranged offset with respect to the first guide pin towards the handle end of the actuating lever when the actuating lever is in the latched position.

Erfindungsgemäß kann aber auch vorgesehen sein, daß im Betätigungshebel zumindest eine, an der Lagerplatte angreifende, den Betätigungshebel in Öffnungsrichtung beaufschlagende Feder vorgesehen und daß das am Schwenkbügel angreifende Betätigungselement aus einer oberhalb des Schwenkbügels angeordneten Nocke und einem den Schwenkbügel untergreifenden Vorsprung besteht, wobei bei in der Verrastungsstellung befindlichem Betätigungshebel die von der Feder auf den Betätigungshebel aufgebrachte Kraft gegenüber dem ersten Führungsstift zum Griffende des Betätigungshebels hin versetzt angeordnet ist.According to the invention, however, it can also be provided that at least one spring, which engages the bearing plate and acts on the actuating lever in the opening direction, is provided in the actuating lever and that the actuating element acting on the swivel bracket consists of a cam arranged above the swivel bracket and a projection engaging under the swivel bracket, with in the latching position of the operating lever, the force applied by the spring to the operating lever relative to the first guide pin Handle end of the operating lever is arranged offset.

Die im Betätigungshebel angeordnete Feder der Verschlußmechanik kann eine Blattfeder sein, die mit einem Ende im Betätigungshebel an einer, gegenüber der Lagerplatte zum Griffende des Betätigungshebels hin versetzten Stelle verankert ist und auf der Lagerplatte, oder einem Vorsprung derselben oben aufliegt. Alternativ dazu kann auch eine am Betätigungshebel und an der Lagerplatte angreifende Schraubenzugfeder oder Schraubendruckfeder vorgesehen sein, die den Betätigungshebel in Öffnungsrichtung beaufschlagt. Weiters können auch mehrere Federn zur Erzeugung eines auf den Betätigungshebel in Öffnungsrichtung wirkenden Drehmoments vorgesehen werden.The spring of the locking mechanism arranged in the actuating lever can be a leaf spring which is anchored at one end in the actuating lever at a point offset from the bearing plate towards the handle end of the actuating lever and rests on the bearing plate or a projection thereof at the top. As an alternative to this, a helical tension spring or helical compression spring acting on the actuating lever and on the bearing plate can also be provided, which acts on the actuating lever in the opening direction. Furthermore, a plurality of springs can also be provided to generate a torque acting on the actuating lever in the opening direction.

In weiterer Ausgestaltung der Erfindung kann vorgesehen sein, daß die zweite Führung eine, vorzugsweise an der Lagerplatte ausgebildete, im wesentlichen dreieckförmige Bewegungsbahn für einen, vorzugsweise am Betätigungshebel befestigten zweiten Führungsstift aufweist, wobei in jeder Ecke der Bewegungsbahn ein, einer der Stellungen des Betätigungshebels entsprechender Anschlag für den zweiten Führungsstift ausgebildet ist. Diese Bewegungsbahn kann in einem, auf die Lagerplatte aufgesetzten eigenen Führungselement ausgebildet sein.In a further embodiment of the invention, it can be provided that the second guide has a substantially triangular movement path, preferably formed on the bearing plate, for a second guide pin, preferably fastened to the actuating lever, one in each corner of the movement path corresponding to one of the positions of the actuating lever Stop for the second guide pin is formed. This movement path can be formed in a separate guide element placed on the bearing plate.

Ein weiteres Merkmal der Erfindung sieht vor, daß die Bewegungsbahn in einer Aussparung der Lagerplatte ausgebildet ist. Diese Ausbildung ist bei der Herstellung der Lagerplatte durch Ausstanzen aus einem Metallblech von Vorteil, weil die Aussparungen beider Führungen gleich mitausgestanzt werden können.Another feature of the invention provides that the movement path is formed in a recess in the bearing plate. This training is advantageous in the manufacture of the bearing plate by punching out of a metal sheet, because the cutouts of both guides can be punched out at the same time.

Ein weiteres Merkmal der Erfindung besteht darin, daß die Bewegungsbahn in einer Vertiefung des Betätigungshebels ausgebildet ist, in der der an der Lagerplatte befestigte zweite Führungsstift bewegbar ist. Diese Ausbildung erlaubt eine einfache Herstellung beider Führungen als Vertiefungen in einem als Kunststoffspritzgußteil hergestellten Betätigungshebel.Another feature of the invention is that the movement path is formed in a recess of the actuating lever in which the second guide pin fastened to the bearing plate can be moved. This design allows easy production of both guides as recesses in an actuating lever made as a plastic injection molded part.

In weiterer Ausgestaltung der Erfindung kann vorgesehen sein, daß die zweite Führung eine mit der Lagerplatte und dem Betätigungshebel gelenkig verbundene Schwinge aufweist, bei der eine ihrer Anlenkungen zum freien Verschwenken des Betätigungshebels aus der Verrastungsstellung in die Verschlußstellung verschiebbar ausgebildet ist.In a further embodiment of the invention it can be provided that the second guide has a rocker arm articulated to the bearing plate and the actuating lever, in which one of its articulations for free pivoting of the actuating lever is designed to be displaceable from the locked position into the closed position.

Ein weiteres Merkmal der Erfindung besteht darin, daß die Schwinge mittels eines, in einem Langschlitz geführten Schwenkzapfens an der Lagerplatte angelenkt ist. Nachstehend wird die Erfindung an, in den Zeichnungen dargestellten Ausführungsbeispielen näher erläutert.Another feature of the invention is that the rocker is articulated on the bearing plate by means of a pivot pin guided in an elongated slot. The invention is explained in more detail below on exemplary embodiments illustrated in the drawings.

In all of the exemplary embodiments, the two guides are formed in the region of the front end 11 of the actuating lever 6, while the rear end of the actuating lever 6, which projects laterally beyond the mandrels 2, 3, is designed as a handle end 13.

Bei den Ausführungsbeispielen der Fig. 1-8 und 13-16 sind beide Führungen 7,8 von, in der Lagerplatte 5 vorgesehenen Aussparungen einerseits und in diese Aussparungen eingreifenden, am jeweiligen Betätigungshebel befestigten Stiften andererseits ausgebildet.In the exemplary embodiments of FIGS. 1-8 and 13-16, both guides 7, 8 are formed by recesses provided in the bearing plate 5 on the one hand and pins engaging in these recesses and fastened to the respective actuating lever on the other hand.

Beim Ausführungsbeispiel der Fig. 9-12 greifen an der Lagerplatte 5 befestigte Stifte in Aussparungen bzw. Vertiefungen im Betätigungshebel 6 ein.In the embodiment of FIGS. 9-12, pins attached to the bearing plate 5 engage in recesses or depressions in the actuating lever 6.

Beim Ausführungsbeispiel der Fig. 17-20 besteht die eine Führung aus einem am Betätigungshebel 6 befestigten Stift, der in eine Aussparung der Lagerplatte 5 eingreift, und die andere Führung aus einer die Lagerplatte 5 mit dem Betätigungshebel 6 beweglich verbindenden Schwinge 22.In the exemplary embodiment in FIGS. 17-20, one guide consists of a pin fastened to the actuating lever 6, which engages in a recess in the bearing plate 5, and the other guide consists of a rocker arm 22 which movably connects the bearing plate 5 to the actuating lever 6.

Bei den in den Fig. 1-8 dargestellten Ausführungsbeispielen besteht die, der Bodenplatte 2 näher angeordnete, erste Führung 7 aus einem L-förmigen Schlitz 14, in dem ein, am Vorderende 11 des Betätigungshebels 6 angeordneter erster Führungsstift 15 geführt ist, gegenüber dem das Betätigungselement 10 zum Griffende 13 hin um das Maß (a) versetzt angeordnet ist. Das in Fig. 1 linke Ende des Schlitzes 14 bildet die, der Verschlußstellung des Betätigungshebels 6 zugeordnete, erste Rastposition A des Führungsstiftes 15 und das obere Schlitzende die, der Endstellung des Betätigungshebels 6 zugeordnete, zweite Rastposition B des Führungsstiftes 15, wobei der obere Rand des Schlitzes 14 eine Führungskurve 16 bildet, die die beiden Rastpositionen A und B verbindet und an der der erste Führungsstift 15 während der Bewegung des Betätigungshebels 6 entlanggleitet. Die über der ersten Führung 7 angeordnete zweite Führung 8 besteht aus einer dreieckförmigen, mit einer Spitze des Dreiecks nach oben angeordneten Aussparung 17 in der Lagerplatte 5 und aus einem, am Vorderende 11 des Betätigungshebels 6 befestigten, zweiten Führungsstift 18, der in diese Aussparung 17 eingreift. Die drei abgerundeten Ecken der Aussparung 17 bilden den verschiedenen Stellungen des Betätigungshebels zugeordnete Anschläge C,D,E für den zweiten Führungsstift 18, wobei der obere Anschlag C der Endstellung des Betätigungshebels 6, der in Fig. 1 linke Anschlag D der Verschlußstellung des Betätigungshebels 6 und der in Fig. 1 rechte Anschlag E der Verrastungsstellung des Betätigungshebels 6 zugeordnet ist.In the exemplary embodiments shown in FIGS. 1-8, the first guide 7, which is arranged closer to the base plate 2, consists of an L-shaped slot 14 in which a first guide pin 15, which is arranged at the front end 11 of the actuating lever 6, is guided relative to the the actuating element 10 is arranged offset to the handle end 13 by the dimension (a). The left end of the slot 14 in FIG. 1 forms the first latching position A of the guide pin 15 assigned to the closed position of the actuating lever 6 and the upper slot end forms the second latching position B of the guide pin 15 assigned to the end position of the actuating lever 6, the upper edge of the slot 14 forms a guide curve 16 which connects the two locking positions A and B and along which the first guide pin 15 slides during the movement of the actuating lever 6. The second guide 8 arranged above the first guide 7 consists of a triangular cutout 17 in the bearing plate 5, with a tip of the triangle pointing upwards, and a second guide pin 18, which is fastened to the front end 11 of the actuating lever 6 and which fits into this cutout 17th intervenes. The three rounded corners of the recess 17 form the stops C, D, E assigned to the different positions of the actuating lever for the second guide pin 18, the upper stop C being the end position of the actuating lever 6 and the left stop D in FIG. 1 being the closed position of the actuating lever 6 and the right stop E in FIG. 1 is assigned to the latching position of the actuating lever 6.

In der Verschlußstellung (Fig. 1,2,7,8) des Betätigungshebels 6 befindet sich der erste Führungsstift 15 im Schlitz 14 in der ersten Rastposition A und der Betätigungshebel 6 wird mit seinem zweiten Führungsstift 18 durch den federbelasteten, am Betätigungselement 10 angreifendem Schwenkbügel 4 gegen den Anschlag D in der Aussparung 17 gedrückt gehalten, wobei der Betätigungshebel 6 selbst in einer, zur Bodenplatte 2 im wesentlichen parallelen Lage im Abstand von der Bodenplatte 2 liegt. In dieser Verschlußstellung liegen die Enden der Dorne 1,3 bei geschlossener Umlegeführung aneinander an.In the closed position (FIGS. 1, 2, 7, 8) of the actuating lever 6, the first guide pin 15 is located in the slot 14 in the first latching position A and the actuating lever 6 is with its second guide pin 18 by the spring-loaded pivot bracket acting on the actuating element 10 4 pressed against the stop D in the recess 17, the actuating lever 6 itself being in a position substantially parallel to the base plate 2 at a distance from the base plate 2. In this closed position, the ends of the mandrels 1, 3 abut one another when the guide is closed.

Zum Öffnen der Umlegeführung hebt man den Betätigungshebel 6 am Griffende 13 so lange an, bis der erste Führungsstift 15 entlang der Führungskurve 16 in den nach oben verlaufenden Teil des Schlitzes 14 kommt. Ab dann wird der Betätigungshebel 6 vom federbelasteten Schwenkbügel 4 in seine Endstellung bewegt. (Fig. 3,4). Dabei gleitet der erste Führungsstift 15 entlang der Führungskurve 16 bis in die zweite Rastposition B des Schlitzes 14, während der zweite Führungsstift 18 entlang der, in Fig. 1 linken Begrenzung der Aussparung 17 vom Anschlag D bis zum Anschlag C gelangt (Fig. 5). In der Endstellung ist die Umlegeführung maximal geöffnet und der Betätigungshebel bleibt etwas unterhalb der, durch die Dornenden bei offener Umlegeführung definierten Ebene.To open the diverter, the actuating lever 6 on the handle end 13 is raised until the first guide pin 15 comes along the guide curve 16 into the upwardly extending part of the slot 14. From then on, the actuating lever 6 is moved into its end position by the spring-loaded swivel bracket 4. (Fig. 3,4). The first guide pin 15 slides along the guide curve 16 into the second latching position B of the slot 14, while the second guide pin 18 travels from the stop D to the stop C along the boundary of the recess 17 on the left in FIG. 1 (FIG. 5) . In the end position, the diverter guide is open to the maximum and the actuating lever remains slightly below that through the mandrel ends with open diversion defined level.

Zum Schließen der Umlegeführung drückt man in der Endstellung (Fig. 3) auf das Griffende 13 des Betätigungshebels 6, wobei der erste Führungsstift 15 wieder entlang der Führungskurve 16 des Schlitzes 14 aus der zweiten Rastposition B zurück in die erste Rastposition A gleitet, während der zweite Führungsstift 18 entlang der, in Fig. 1 rechten Begrenzung der Aussparung 17 vom Anschlag C bis zum Anschlag E gleitet. Dabei gelangt das Griffende 13 des Betätigungshebels in seine, der Bodenplatte 2 am nächsten gelegenen Lage und der Betätigungshebel 6 in seine Verrastungsstellung (Fig. 6). Läßt man nun das Griffende 13 des Betätigungshebels 6 los, so wird dieser unter der Wirkung des federbelasteten Schwenkbügels 4, der auf das, gegenüber dem Führungsstift 15 versetzte Betätigungselement 10 drückt, so lange um den ersten Führungsstift 15 verschwenkt, bis der zweite Führungsstift 18 vom Anschlag E zum Anschlag D gelangt ist und nimmt dann wieder die Verschlußstellung ein, in der das Griffende 13 problemlos untergriffen werden kann.To close the diverter, in the end position (FIG. 3), press on the handle end 13 of the actuating lever 6, the first guide pin 15 again sliding along the guide curve 16 of the slot 14 from the second latching position B back into the first latching position A, during the second guide pin 18 slides along the right limit of the recess 17 in FIG. 1 from the stop C to the stop E. The handle end 13 of the actuating lever comes into its position closest to the base plate 2 and the actuating lever 6 into its locked position (FIG. 6). If you now let go of the handle end 13 of the actuating lever 6, this is pivoted around the first guide pin 15 under the action of the spring-loaded swivel bracket 4, which presses on the actuating element 10 offset relative to the guide pin 15, until the second guide pin 18 from Stop E has come to stop D and then returns to the closed position, in which the handle end 13 can be gripped easily.

Während der Bewegung des Betätigungshebels 6 gleitet der erste Führungsstift 15 im Schlitz 14 immer an derselben Führungskurve 16 entlang, während der zweite Führungsstift 18 in der Aussparung 17 einmal deren linkem Rand (von D nach C) und einmal deren rechten Rand (von C nach E) folgt.During the movement of the actuating lever 6, the first guide pin 15 in the slot 14 always slides along the same guide curve 16, while the second guide pin 18 in the recess 17 has its left edge (from D to C) and its right edge (from C to E ) follows.

Beim Ausführungsbeispiel der Fig. 9-12 besteht die, der Bodenplatte 2 nähere, erste Führung 7 aus einem, an der Lagerplatte 5 befestigten ersten Führungsstift 15, der in einer, im Betätigungshebel 6 ausgebildeten L-förmigen Aussparung oder Vertiefung 19 geführt ist. Die zweite Führung 8 besteht aus einem, oberhalb des ersten Führungsstiftes 15 an der Lagerplatte 5 befestigten Führungsstift 18, der in einer, im Betätigungshebel 6 ausgebildeten Vertiefung 20 mit dreieckförmigem Umriß bewegbar ist. Bei der ersten Führung 7 ist das in Fig. 9 rechte Ende der Vertiefung 19 die erste Rastposition A′ des ersten Führungsstiftes 15 und das in Fig. 9 linke, untere Ende der Vertiefung 19 die zweite Rastposition B′. Bei der zweiten Führung 8 sind wieder die den Ecken des Dreieckes entsprechenden Stellen des, mit einer Spitze nach unten angeordneten Umrisses der Vertiefung 20 als Anschläge für den zweiten Führungsstift 18 ausgebildet, wobei das in Fig. 9 untere Eck den, der Endstellung des Betätigungshebels zugeordneten Anschlag C′, das in Fig. 9 linke, obere Eck den, der Verrastungsstellung zugeordneten Anschlag E′ und das in Fig. 9 rechte obere Eck den, der Verschlußstellung zugeordneten Anschlag D′ für den zweiten Führungsstift 18 bildet.In the exemplary embodiment of FIGS. 9-12, the first guide 7, which is closer to the base plate 2, consists of a first guide pin 15 fastened to the bearing plate 5, which is guided in an L-shaped recess or depression 19 formed in the actuating lever 6. The second guide 8 consists of a guide pin 18 which is fastened to the bearing plate 5 above the first guide pin 15 and which can be moved in a recess 20 formed in the actuating lever 6 with a triangular outline. In the first guide 7, the right end of the recess 19 in FIG. 9 is the first latching position A 'of the first guide pin 15 and the left lower end of the recess 19 in FIG. 9 is the second latching position B'. In the second guide 8 are the corners of the triangle corresponding points of the, with a point downward outline of the recess 20 formed as stops for the second guide pin 18, the lower corner in Fig. 9, the end position of the actuating lever associated stop C ', the upper left in Fig. 9 Corner, the stop position assigned to E 'and the upper right corner in Fig. 9, the stop position assigned to D' forms for the second guide pin 18.

In Fig. 9 liegt der Betätigungshebel 6 in seiner Endstellung mit dem linken unteren Ende der Vertiefung 19 am ersten Führungsstift 15 in der Rastposition B′ an und mit dem unteren Eck der Vertiefung 20 am zweiten Führungsstift 18 im Anschlag C′ an. Drückt man das Griffende 13 des Betätigungshebels 6 nieder, so gleitet die Vertiefung 19 mit ihrem unteren Rand an der Unterseite des ersten Führungsstiftes 15 entlang, bis dieser am rechten Ende der Vertiefung 19 anstößt, während die Vertiefung 20 mit ihrem linken Rand an der linken Seite des zweiten Führungsstiftes 18 entlanggleitet (Fig. 11) bis dieser mit seiner Oberseite an den Anschlag E′ stößt, wobei das Griffende 13 in seine der Bodenplatte 2 nächstgelegene Position und der Betätigungshebel in seine Verrastungsstellung gelangt (Fig. 10). Läßt man nun das Griffende los, so schwenkt der Betätigungshebel 6 unter der Wirkung des federbelasteten (nicht dargestellten) Schwenkarmes um den ersten Führungsstift 15 bis die Vertiefung 20 mit dem Anschlag D′ am zweiten Führungsstift 18 anstößt und der Betätigungshebel in der Verschlußstellung ist (Fig. 12).In Fig. 9, the actuating lever 6 is in its end position with the lower left end of the recess 19 on the first guide pin 15 in the locking position B 'and with the lower corner of the recess 20 on the second guide pin 18 in the stop C'. If the handle end 13 of the actuating lever 6 is depressed, the recess 19 slides with its lower edge along the underside of the first guide pin 15 until it abuts the right end of the recess 19, while the recess 20 with its left edge on the left side of the second guide pin 18 slides along (Fig. 11) until it abuts the stop E 'with its upper side, the handle end 13 coming into its position closest to the base plate 2 and the actuating lever into its latching position (Fig. 10). If you now let go of the handle end, the actuating lever 6 pivots under the action of the spring-loaded (not shown) pivot arm about the first guide pin 15 until the recess 20 with the stop D 'abuts the second guide pin 18 and the actuating lever is in the closed position (Fig . 12).

Das Ausführungsbeispiel der Fig. 13-16 entspricht im wesentlichen dem der Fig. 1-6, wobei gegenüber diesem lediglich die erste Führung 7 mit ihrem L-förmigen Schlitz 14 oberhalb der zweiten Führung 8 mit ihrer dreieckförmigen Aussparung 17 angeordnet ist und die Rastposition B˝,A˝ bzw. die Anschläge D˝,E˝ spiegelbildlich vertauscht angeordnet sind.The exemplary embodiment of FIGS. 13-16 corresponds essentially to that of FIGS. 1-6, with only the first guide 7 with its L-shaped slot 14 being arranged above the second guide 8 with its triangular recess 17 and the detent position B ˝, A˝ or the stops D˝, E˝ are reversed mirror images.

Bei dem in den Fig. 17-20 dargestellten Ausführungsbeispiel besteht die, der Bodenplatte 7 näher angeordnete erste Führung 7 aus einer Aussparung 21 der Lagerplatte 5, in der ein am Vorderende 11 des Betätigungshebels 6 angeordneter erster Führungsstift 15 geführt ist, gegenüber dessen Betätigungselement 10 zum Griffende 13 hin um das Maß (a) versetzt angeordnet ist, wobei in der Aussparung 21 die der Verschlußstellung des Betätigungshebels 6 zugeordnete erste Rastposition A des Führungsstiftes 15 und die der Endstellung des Betätigungshebels 6 zugeordnete, zweite Rastposition B des Führungsstiftes 15, und eine L-förmige Führungskurve 16 vorgesehen ist, die die beiden Rastpositionen A und B verbindet und an der der erste Führungsstift 15 während der Bewegung des Betätigungshebels 6 entlanggleitet. Die zweite Führung 8 ist als Schwinge 22 ausgebildet, die an einem Ende an einem, am Betätigungshebel 6 befestigten oberen Schwenkzapfen 23 angelenkt ist und am anderen Ende an einem unteren Schwenkzapfen 24 angelenkt ist, der in einem Langschlitz 25 der Lagerplatte 5 verschiebbar geführt ist.In the exemplary embodiment shown in FIGS. 17-20, the first guide 7, which is arranged closer to the base plate 7, consists of a recess 21 in the bearing plate 5, in which a first one is arranged at the front end 11 of the actuating lever 6 Guide pin 15 is guided, opposite its actuating element 10 to the handle end 13 is offset by the dimension (a), the first detent position A of the guide pin 15 associated with the closed position of the actuating lever 6 and the end position of the actuating lever 6 associated with the locking position of the actuating lever 6, second locking position B of the guide pin 15, and an L-shaped guide curve 16 is provided which connects the two locking positions A and B and along which the first guide pin 15 slides during the movement of the actuating lever 6. The second guide 8 is designed as a rocker arm 22, which is articulated at one end to an upper pivot pin 23 fastened to the actuating lever 6 and is articulated at the other end to a lower pivot pin 24 which is guided in a long slot 25 of the bearing plate 5.

In der Verschlußstellung (Fig. 17) des Betätigungshebels 6 befindet sich der erste Führungsstift 15 in der Aussparung 21 in der ersten Rastposition A und der Betätigungshebel 6 wird mit der Schwinge 22 und deren unterem Schwenkzapfen 24 durch den federbelasteten, am Betätigungselement 10 angreifenden Schwenkbügel 4, welcher dem Hebel 6 ein gegen den Uhrzeigersinn gerichtetes Drehmoment aufzwingt, gegen das untere Ende des Langschlitzes 25 gedrückt gehalten, wobei der Betätigungshebel 6 selbst in einer, zur Bodenplatte 2 im wesentlichen parallelen Lage im Abstand von der Bodenplatte 2 liegt. In dieser Verschlußstellung liegen die Enden der Dorne 1,3 bei geschlossener Umlegeführung aneinander an (Fig. 18).In the closed position (FIG. 17) of the actuating lever 6, the first guide pin 15 is located in the recess 21 in the first latching position A and the actuating lever 6 is with the rocker arm 22 and its lower pivot pin 24 by the spring-loaded pivot bracket 4 acting on the actuating element 10 , which forces a counterclockwise torque on the lever 6, is pressed against the lower end of the elongated slot 25, the actuating lever 6 itself being in a position substantially parallel to the base plate 2 at a distance from the base plate 2. In this closed position, the ends of the mandrels 1, 3 abut one another when the guide is closed (FIG. 18).

Zum Öffnen der Umlegeführung hebt man den Betätigungshebel 6 am Griffende 13 so lange an, bis der erste Führungsstift 15 entlang der Führungskurve 16 in den nach oben verlaufenden Teil der Aussparung 21 kommt. Ab dann wird der Betätigungshebel 6 vom federbelasteten Schwenkbügel 4 in seine Endstellung bewegt (Fig. 19). Dabei gleitet der erste Führungsstift 15 entlang der Führungskurve 16 bis in die zweite Rastposition B der Aussparung 21, während der untere Schwenkzapfen 24 der Schwinge 22 im Langschlitz 25 nach oben gleitet, bis er am oberen Ende des Langschlitzes 25 anstößt, wobei die Schwinge 22 etwas nach oben schwenkt. In der Endstellung ist die Umlegeführung maximal geöffnet und der Betätigungshebel bleibt etwas unterhalb der, durch die Dornenden bei offener Umlegeführung definierten Ebene.In order to open the diverter guide, the actuating lever 6 on the handle end 13 is raised until the first guide pin 15 comes along the guide curve 16 into the part of the recess 21 which runs upwards. From then on, the actuating lever 6 is moved into its end position by the spring-loaded swivel bracket 4 (FIG. 19). The first guide pin 15 slides along the guide curve 16 into the second latching position B of the recess 21, while the lower pivot pin 24 of the rocker 22 slides upwards in the elongated slot 25 until it abuts the upper end of the elongated slot 25, the rocker 22 swings slightly upwards. In the end position, the diverter guide is opened to the maximum and the actuating lever remains somewhat below the level defined by the mandrel ends when the diverter guide is open.

Zum Schließen der Umlegeführung drückt man in der Endstellung (Fig. 19) auf das Griffende 13 des Betätigungshebels 6, wobei der erste Führungsstift 15 wieder entlang der Führungskurve 16 der Aussparung 21 aus der zweiten Rastposition B zurück in die erste Rastposition A gleitet, während der untere Schwenkzapfen 24 der Schwinge 22 in seiner oberen Endstellung verbleibt und sowohl der Betätigungshebel 6 um den oberen Schwenkzapfen 23 der Schwinge 22 als auch die Schwinge 22 selbst geschwenkt werden. Dabei gelangt das Griffende 13 des Betätigungshebels in seine, der Bodenplatte 2 am nächsten gelegene Lage und der Betätigungshebel 6 in seine Verrastungsstellung (Fig. 20). Läßt man nun das Griffende 13 des Betätigungshebels 6 los, so schwenkt dieser im Gegenuhrzeigersinn unter der Wirkung des federbelasteten Schwenkbügels 4 um den ersten Führungsstift 15 so lange, bis der untere Schwenkzapfen 24 der Schwinge 22 im Langschlitz 25 am unteren Ende anstößt, und nimmt dann wieder die Verschlußstellung ein, in der das Griffende 13 problemlos untergriffen werden kann.To close the diverter guide, in the end position (FIG. 19), press on the handle end 13 of the actuating lever 6, the first guide pin 15 again sliding along the guide curve 16 of the recess 21 from the second latching position B back into the first latching position A, during the the lower pivot 24 of the rocker 22 remains in its upper end position and both the actuating lever 6 about the upper pivot 23 of the rocker 22 and the rocker 22 itself are pivoted. The handle end 13 of the actuating lever comes into its position closest to the base plate 2 and the actuating lever 6 into its locked position (FIG. 20). If you now let go of the handle end 13 of the actuating lever 6, it pivots counterclockwise under the action of the spring-loaded pivot bracket 4 around the first guide pin 15 until the lower pivot pin 24 of the rocker arm 22 abuts in the elongated slot 25 at the lower end, and then takes again the closed position, in which the handle end 13 can be easily gripped.

Während der Bewegung des Betätigungshebels 6 gleitet der erste Führungsstift 15 in der Aussparung 21 immer an derselben Führungskurve 16 entlang und der am Betätigungshebel 6 befestigte, obere Schwenkzapfen 23 folgt einer etwa dreiecksförmigen, in sich geschlossenen Bewegungsbahn. Bei der Bewegung des Betätigungshebels 6 von der Endstellung in die Verrastungsstellung folgt der obere Schwenkzapfen 23 einem Kreisbogen um den, am oberen Ende des Langschlitzes 25 anliegenden unteren Schwenkzapfen 24, bei der Hebelbewegung von der Verrastungsstellung in die Verschlußstellung einem Kreisbogen um den, in der Rastposition A befindlichen ersten Führungsstift 15 und bei der Hebelbewegung aus der Verschlußstellung einem Kreisbogen um den, am unteren Ende des Langschlitzes 25 anliegenden unteren Schwenkzapfen 24 bis der erste Führungsstift 15 seine Rastposition A verlassen hat und an der Führungskurve 16 entlanggleitet.During the movement of the actuating lever 6, the first guide pin 15 always slides in the recess 21 along the same guide curve 16 and the upper pivot pin 23 attached to the actuating lever 6 follows an approximately triangular, self-contained movement path. When the actuating lever 6 moves from the end position into the latching position, the upper pivot pin 23 follows a circular arc around the lower pivot pin 24, which rests against the upper end of the elongated slot 25, and a circular arc around the lever movement from the latched position into the closed position in the latched position A located first guide pin 15 and in the lever movement from the closed position, a circular arc around the lower pivot pin 24 resting on the lower end of the elongated slot 25 until the first guide pin 15 has left its latching position A and on the guide curve 16 slides along.
