Abstract

Tool for tying an article, especially a cable harness (19), by means of a band consisting of a band tongue (7) and of a buckle which is fixedly connected to the latter and which has a band orifice (25) for receiving and retaining the free end (30) of the band tongue and, in the tied state, at least one region (34) projecting laterally. For guiding the band tongue around the article to be tied, the tool comprises a looping-round guide (15) which has at least one movable part for opening and closing. To hold the buckle during the tying operation, there is provided a buckle mounting which is formed at least partially by a part (21) retaining the laterally projecting region of the buckle. So that the part (21) does not impede the extraction of the buckle from the buckle mounting, it is removable. To avoid a special support, drive device and control, according to the invention this part (21) is connected to the movable part (16) of the looping-round guide. <IMAGE>

Description

Die Erfindung betrifft ein Werkzeug zum Binden eines Gegenstands, insbesondere eines Kabelbaums, mittels eines Bandes, das aus einer Bandzunge und einem damit fest verbundenen Schloß besteht, das eine Bandöffnung zum Aufnehmen und Festhalten des freien Endes der Bandzunge und wenigstens einen seitlich vorspringenden Bereich aufweist. Zum Führen der Bandzunge um den zu bindenden Gegenstand umfaßt das Werkzeug eine Umschlingungsführung, von der wenigstens ein Teil zum Öffnen und Schließen der Umschlingungsführung beweglich ist. Zum Halten des Schlosses während des Bindevorgangs ist angrenzend an den von der Umschlingungsführung eingeschlossenen, zur Aufnahme des zu bindenden Gegenstands freien Bereich eine Schloßhalterung vorgesehen. Diese ist zumindest teilweise von einem Teil gebildet, der zur Freigabe der Entnahme des Schlosses aus der Schloßhalterung nach dem Bindevorgang entfernbar ist, aber während des Bindevorgangs vor den seitlich vorspringenden Bereich des Schlosses faßt.The invention relates to a tool for binding an object, in particular a wire harness, by means of a band consisting of a band tongue and a lock firmly connected to it, which has a band opening for receiving and holding the free end of the band tongue and at least one laterally projecting area. To guide the strap tongue around the object to be bound, the tool comprises a loop guide, at least part of which is movable for opening and closing the loop guide. To hold the lock during the binding process, a lock holder is provided adjacent to the area enclosed by the loop guide and free for receiving the object to be bound. This is at least partially formed by a part which can be removed to release the removal of the lock from the lock holder after the binding process, but which grips in front of the laterally projecting region of the lock during the binding process.

Das Schloß muß während des Bindevorgangs sicher gehalten werden, damit die in die Bandöffnung des Schlosses einzuführende Spitze der Bandzunge diese Öffnung richtig treffen kann. Ein seitlich vorspringender Bereich des Schlosses kann zum Halten des Schlosses herangezogen werden, weil Teile der Schloßhalterung vor diesen Bereich greifen können. Die seitliche Richtung ist in diesem Zusammenhang auf die Entnahmerichtung des Schlosses zu beziehen. Ein vorspringender Bereich zeichnet sich durch wenigstens eine Fläche aus, die eine quer zur Entnahmerichtung verlaufende Komponente besitzt, die in Entnahmerichtung blickt.The lock must be held securely during the binding process so that the tip of the tongue to be inserted into the strap opening of the lock can correctly meet this opening. A laterally projecting area of the lock can be used to hold the lock because parts of the lock holder can reach in front of this area. In this context, the lateral direction is related to the removal direction of the lock. A projecting area is characterized by at least one surface that has a component that runs transversely to the removal direction and that looks in the removal direction.

Ein vorspringender Bereich ist aber nicht nur nützlich hinsichtlich des Halterungszwecks, sondern kann auch hinderlich sein bei der Entnahme des Schlosses, solange ein Halterungsteil davor greift. Ein solches Halterungsteil muß deshalb nach dem Bindevorgang zur Entnahme des Schlosses entfernbar sein. In diesem Zusammenhang sind nicht nur solche seitlich vorspringenden Bereich des Schlosses in Betracht zu ziehen, die daran ursprünglich vorhanden sind, sondern auch solche, die erst durch den Bindevorgang entstehen wie beispielsweise ein über die Bandöffnung des Schlosses vorstehendes Ende der Bandzunge. Der Antrieb und die Steuerung beweglicher Halterungsteile ist aufwendig, das gilt zumal in Anbetracht der beengten Platzverhältnisse im Halterungsbereich.A projecting area is not only useful with regard to the purpose of the holder, but can also be a hindrance when removing the lock, as long as a holder part engages in front of it. Such a mounting part must therefore be removable after the binding process for removing the lock. In this context, not only those areas of the lock that protrude laterally that originally exist on it should be taken into account, but also those that only arise through the binding process, such as an end of the strap tongue protruding beyond the strap opening of the lock. The drive and the control of movable mounting parts is complex, especially considering the limited space in the mounting area.

Die Erfindung sucht deshalb nach einer einfachen Lösung zur Bewegung und Steuerung eines entfernbaren Teil der Schloßhalterung und findet die Lösung in den Merkmalen des Anspruchs 1, vorzugsweise auch der Unteransprüche.The invention therefore looks for a simple solution for moving and controlling a removable part of the lock holder and finds the solution in the features of claim 1, preferably also the subclaims.

Die Verbindung des entfernbaren Halterungsteils mit dem beweglichen Teil der Umschlingungsführung erübrigt es, für den entfernbaren Halterungsteil besondere Lagerungs-, Antriebs- und Steuerungsorgane vorzusehen. Dies ergibt eine beträchtliche Vereinfachung und einen wesentlichen Platzgewinn. Außerdem wird eine Auswerferwirkung auf das Schloß bzw. auf den gebundenen Gegenstand ausgeübt, wenn der entfernbare Teil der Schloßhalterung hinter einen Teil des Schlosses oder des gebundenen Gegenstands greift und dadurch das Schloß oder den gebundenen Gegenstand bei der Öffnungsbewegung der Umschlingungsführung mitnimmt. Die Erfindung ist unabhängig davon anwenden, in welcher Weise der bewegliche Teil der Umschlingungsführung geführt ist. Die einfachste und zweckmäßigste Form der Führung ist die Schwenkführung. Wenn die Schwenkachse in bezug auf die Entnahmerichtung hinter der Schloßhalterung liegt, erhält der entfernbare Teil der Halterung eine seitlich vom Schloß weg gerichtete Bewegungskomponente. Wenn die Schwenkachse in bezug auf die Entnahmerichtung neben der Schloßhalterung auf der Seite des beweglichen Teils der Umschlingungsführung liegt, erhält der entfernbare Halterungsteil eine Bewegungskomponente in Entnahmerichtung. Zweckmäßigerweise werden beide Bewegungsrichtungen miteinander kombiniert, so daß die Bewegungsrichtung des entfernbaren Halterungsteils beim Öffnen der Halterung schräg zur Seite und in Entnahmerichtung bewegt wird.The connection of the removable holder part to the movable part of the loop guide makes it unnecessary to provide special mounting, drive and control elements for the removable holder part. This results in a considerable simplification and a substantial saving of space. In addition, an ejector effect is exerted on the lock or on the bound object if the removable part of the lock holder reaches behind a part of the lock or the bound object and thereby entrains the lock or the bound object during the opening movement of the loop guide. The invention is applicable regardless of the manner in which the movable part of the loop guide is guided. The simplest and most practical form of the guide is the swivel guide. If the pivot axis lies behind the lock holder with respect to the removal direction, the removable part of the holder receives a movement component directed laterally away from the lock. If the pivot axis is located on the movable part of the loop guide with respect to the removal direction next to the lock holder, the removable holder part receives a movement component in the removal direction. Both directions of movement are expediently combined with one another, so that the direction of movement of the removable holder part is moved obliquely to the side and in the removal direction when the holder is opened.

Bei einer besonders zweckmäßigen Ausführungsform der Erfindung umfaßt der entfernbare Teil der Schloßhalterung einen Sporn, der zwischen das am Schloß befestigte Bandende und das aus der Bandöffnung vorstehende freie Bandende faßt. Dieser Sporn kann den Beginn der Umschlingungsführung bilden.In a particularly expedient embodiment of the invention, the removable part of the lock holder comprises a spur which grips between the strap end fastened to the lock and the free strap end protruding from the strap opening. This spur can form the start of the wrapping guide.

Im Sinne einer Platzersparnis im Bereich der Schloßhalterung ist auch das Erfindungsmerkmal zu sehen, daß der entfernbare Teil der Schloßhalterung ein Widerlager für eine das überstehende Ende der Bandzunge abschneidende Klinge bildet. Ein besonderes Organ für diese Zwecke wird dadurch entbehrlich.In terms of saving space in the area of the lock holder, the feature of the invention can also be seen that the removable part of the lock holder forms an abutment for a blade that cuts off the protruding end of the band tongue. A special organ for these purposes is therefore unnecessary.

Die Erfindung ist besonders nützlich dann, wenn das Schloß am Umfang des größten in dem freien Bereich innerhalb der Umschlingungsführung unterzubringenden Kreises angeordnet ist. Diese Anordnung ist deshalb erstrebenswert, weil dann der zu bindende Gegenstand (beispielsweise Kabelbaum) im Spannvorgang den idealen Kreisumriß annehmen kann, was nicht oder nur bei Inkaufnahme konstruktiver Komplikationen möglich ist, wenn das Schloß seitlich außerhalb dieses Kreises an einem davon ausgehenden Zwickel angeordnet ist (US-A 3 891 012; EP-A 0 264 142, EP-A-0 428 116).The invention is particularly useful when the lock is arranged on the circumference of the largest circle to be accommodated in the free area within the loop guide. This arrangement is desirable because the object to be tied (e.g. cable harness) can then take on the ideal circular outline in the tensioning process, which is not possible or only possible when there are constructional complications if the lock is arranged laterally outside this circle on a gusset extending from it. US-A 3 891 012; EP-A 0 264 142, EP-A-0 428 116).

Die Erfindung wird im folgenden näher unter Bezugnahme auf die Zeichnung erläutert, die ein vorteilhaftes Ausführungsbeispiel veranschaulicht. Darin zeigen:

  • Fig. 1 einen schematischen Längsschnitt durch das Werkzeug und
  • Fig. 2 und 3 Längsschnitte durch den vorderen Werkzeugbereich in größerem Maßstab und unterschiedlichen Funktionsstadien.
The invention is explained in more detail below with reference to the drawing, which illustrates an advantageous embodiment. In it show:
  • Fig. 1 shows a schematic longitudinal section through the tool and
  • 2 and 3 longitudinal sections through the front tool area on a larger scale and different functional stages.

Gemäß Fig.1 besitzt das Werkzeug einen Werkzeugkörper 1 und einen Handgriff 2, an dem es gehalten werden kann. Zwischen den Wänden 3 und 4 des Gehäusekörpers 1 befindet sich ein Führungskanal 5 für ein Band 6 aus zähelastischem Kunststoff wie beispielsweise Polyamid. Es gelangt auf beliebige Weise in die in Fig.1 dargestellte Lage innerhalb des Kanals 5, beispielsweise durch nicht gezeigte automatische Mittel von einem Bändermagazin oder von Hand. Das Band weist eine Bandzunge 7 und einen Kopf 8 auf, wobei die Spitze der Bandzunge zu dem vorderen, in Fig.1 links dargestellten Ende des Werkzeugkörpers weist, während der Kopf 8 sich hinten befindet. Im Führungskanal 5 befindet sich hinter dem Schloß 8 ein Schieberkopf 9, dessen mit dem Schloß 8 zusammenwirkende Stirnseite der Form des Schlosses 8 angepaßt ist und der am vorderen Ende eines flexiblen Stahlbandes 10 befestigt ist, das auf eine Rolle 11 gewickelt ist. Der Kopf 9 und das Stahlband 10 bilden gemeinsam einen Schieber zum Schieben des Bandes 6 aus der in Fig.1 dargestellten Lage in diejenige Stellung (Fig.3) in welcher das Band zum Binden eines Gegenstandes benutzt wird. Wenn die Rolle 11 in Pfeilrichtung 14 gedreht wird, wird das Stahlband 10 mit dem Schieberkopf 9 entlang des Führungskanals 5 nach vorne geschoben.According to Figure 1, the tool has a tool body 1 and a handle 2, on which it can be held. Between the walls 3 and 4 of the housing body 1 there is a guide channel 5 for a band 6 made of tough elastic plastic such as polyamide. It reaches the position shown in FIG. 1 within the channel 5 in any way, for example by automatic means (not shown) from a tape magazine or by hand. The band has a band tongue 7 and a head 8, the tip of the band tongue pointing to the front end of the tool body shown on the left in FIG. 1, while the head 8 is located at the rear. In the guide channel 5 there is a slide head 9 behind the lock 8, the end face cooperating with the lock 8 is adapted to the shape of the lock 8 and is attached to the front end of a flexible steel band 10 which is wound on a roller 11. The head 9 and the steel band 10 together form a slide for pushing the band 6 from the position shown in FIG. 1 to the position (FIG. 3) in which the band is used to bind an object. When the roller 11 is rotated in the direction of the arrow 14, the steel strip 10 with the slide head 9 is pushed forward along the guide channel 5.

Am vorderen Ende weist das Werkzeug eine von den Teilen 15 und 16 gebildete Zange auf. Sie bildet eine Führung für das Band 6 während seines den zu bindenden Gegenstand umschlingenden Wegs. Zangenteil 15 ist um die Achse 17 schwenkbar; Zangenteil 16 ist um die Achse 18 schwenkbar. Es sind Antriebs- und Steuerungsmittel vorgesehen, die die Schwenkung der Zangenteile aus der in Fig.1 dargestellten geöffneten Stellung in weitere Funktionsstellungen besorgen, wie dies weiter unten beschrieben ist. Diese Antriebs- und Steuerungsmittel sind herkömmlicher Art und deshalb nicht dargestellt und erläutert.At the front end, the tool has pliers formed by parts 15 and 16. It forms a guide for the band 6 during its path wrapping around the object to be bound. Pliers part 15 is pivotable about the axis 17; Pliers part 16 is pivotable about the axis 18. Drive and control means are provided which provide for the pivoting of the pliers parts from the open position shown in FIG. 1 to further functional positions, as described below. These drive and control means are conventional and therefore not shown and explained.

In der geöffneten Stellung (Fig.1) nimmt die Zange einen zu bindenden Gegenstand auf, bei dem es sich beispielsweise um ein Bündel von Kabeln 19 (Fig.2) handeln kann, die mittels des Bandes 6 fest zusammengebunden werden sollen, wie dies im Endstadium in Fig.1 dargestellt ist. In diesem Stadium umgibt die Bandzunge 7 unter Spannung das Kabelbündel 19. Das freie Ende der Bandzunge 7 ist durch das Schloß 8 geführt und darin befestigt. Das überstehende Ende der Bandzunge ist abgeschnitten:In the open position (FIG. 1), the tongs pick up an object to be bound, which can be, for example, a bundle of cables 19 (FIG. 2) which are to be firmly bound together by means of the band 6, as is shown in FIG Final stage is shown in Fig.1. At this stage, the band tongue 7 surrounds the cable bundle 19 under tension. The free end of the band tongue 7 is guided through the lock 8 and fastened therein. The protruding end of the tongue is cut off:

Damit die Bandzunge um den zu bindenden Gegenstand 19 geschlungen werden kann, können die Zangenteile 15 und 16 gemäß Fig.2 in eine geschlossene Umschlingungsstellung gebracht werden. Sie enthalten eine Führungsnut 20, deren Breite etwa derjenigen der Bandzunge 7 entspricht und deren Tiefe beträchtlich größer als die Dicke der Bandzunge 7 ist. Die Führungsnut 20 wird an ihrem Beginn durch einen Sporn 21 begrenzt, der fest mit dem Zangenteil 16 verbunden ist. Wenn die Spitze der Bandzunge 7 in den Beginn der Führungsnut 21 eingeführt ist, was durch hier nicht interessierende Mittel (siehe gleichzeitig eingereichte europäische Patentanmeldung mit dem anwaltlichen Aktenzeichen p 15693/93) bewerkstelligt wird, wird ihr weiterer Weg durch diese Nut um den zu bindenden Gegenstand 19 herum bestimmt, der bei 22 am inneren Ende des Zangenteils 15 endet.So that the strap tongue can be wrapped around the object 19 to be bound, the pliers parts 15 and 16 can be brought into a closed looping position according to FIG. They contain a guide groove 20, the width of which corresponds approximately to that of the band tongue 7 and the depth of which is considerably greater than the thickness of the band tongue 7. The guide groove 20 is delimited at its beginning by a spur 21 which is firmly connected to the pliers part 16. If the tip of the band tongue 7 is inserted into the beginning of the guide groove 21, which is accomplished by means of no interest here (see simultaneously filed European patent application with the legal file number p 15693/93), your further path through this groove becomes the one to be bound Object 19 determined around, which ends at 22 at the inner end of the pliers part 15.

Wenn diese Endstellung erreicht ist, hat das Schloß 8 gleichfalls seine Endstellung erreicht, die durch die Schloßhalterung bestimmt ist. Diese besteht aus einem gehäusefesten Halterungssteil 23, dessen dem Schloß 24 zugewendete Oberfläche der Gestalt des Schlosses zumindest teilweise angepaßt ist. Ferner gehören der bereits erwähnte Sporn 21 und der Bereich 35 hinter dem Sporn 21, der in der Zeichnungsebene für den Durchlaß des Bandes ausgeschnitten ist aber seitlich davon (oberhalb und unterhalb der Zeichnung) Anschlagflächen für das Schloß bilden kann, zur Schloßhalterung. In der in Fig. 2 und 3 dargestellten Stellung des Zangenteils 16 bilden der Sporn 21 und der Teil 35 gemeinsam mit dem gehäusefesten Halterungsteil 23 einen Anschlag, der der Form des Schlosses 8 so angepaßt ist, daß dessen Stellung in der Halterung eindeutig bestimmt ist, sofern es gegen diesen Anschlag gedrückt ist. Dies geschieht durch den Schieberkopf 9, der als drittes Halterungsteil ausgebildet ist. Durch eine fortdauernd auf das Stahlband 10 ausgeübte Vorschubkraft, die beispielsweise durch eine Rutschkupplung oder Feder im Antrieb der Rolle 11 bestimmt sein kann, drückt der Schieberkopf 9 das Schloß 8 gegen die Halterungsteile 21, 23 und bestimmt dadurch exakt die Endstellung des Schlosses. Dabei faßt der Sporn 21 zwischen die Bandzunge 7, wo sie einstückig mit dem Schloß 8 verbunden ist, und die Mündung der zur Aufnahme der Bandzunge im Schloß gestrichelt angedeuteten Bandöffnung 25. Das bedeutet, daß die Spitze des Bandes bei der Umschlingungsbewegung (Fig. 2) auf der Vorderseite, aber im Endzustand auf der Rückseite des Sporns durchgehen muß. Der Sporn selbst liegt zwischen diesen beiden Bandbereichen als Anschlag am Schloßkörper an und ist somit an dessen Positionierung beteiligt. Jedoch ist dies nicht unbedingt erforderlich. Erforderlich ist lediglich, daß die Halterungsteile 21, 23, 9 derart mit der Oberfläche des Schloßkörpers zusammenwirken, daß dessen Position eindeutig festgelegt wird.When this end position is reached, the lock 8 has also reached its end position, which is determined by the lock holder. This consists of a housing-fixed mounting part 23, whose surface facing the lock 24 is at least partially adapted to the shape of the lock. Furthermore, the already mentioned spur 21 and the area 35 behind the spur 21, which is cut out in the plane of the drawing for the passage of the band but can form stop surfaces for the lock laterally therefrom (above and below the drawing) for the lock holder. In the position of the pliers part 16 shown in FIGS. 2 and 3, the spur 21 and the part 35 together with the mounting part 23 fixed to the housing form a stop which is adapted to the shape of the lock 8 so that its position in the mounting is clearly determined, if it is pressed against this stop. This is done by the slide head 9, which is designed as a third mounting part. Due to a continuous feed force exerted on the steel strip 10, which can be determined, for example, by a slip clutch or spring in the drive of the roller 11, the slide head 9 presses the lock 8 against the holding parts 21, 23 and thereby determines exactly the end position of the lock. The spur 21 grips between the strap tongue 7, where it is integrally connected to the lock 8, and the mouth of the strap opening 25 indicated by dashed lines for receiving the strap tongue in the lock. This means that the tip of the strap during the wrapping movement (Fig. 2nd ) on the Front, but must go through in the final state on the back of the spur. The spur itself lies between these two band areas as a stop on the lock body and is therefore involved in its positioning. However, this is not absolutely necessary. It is only necessary that the holder parts 21, 23, 9 cooperate with the surface of the lock body in such a way that its position is clearly defined.

Das Schloß ist so geformt, daß das Band etwa in Vorschubrichtung von dem Schloß seinen Ursprung nimmt und daß die Bandöffnung 25 zu dieser Richtung etwa parallel ist. Genaue Parallelität ist nicht erforderlich. Vielmehr könnte die Bandöffnung bei Betrachtung der Fig. 3 beispielsweise auch ein wenig im Gegenuhrzeigersinn gegenüber der dargestellten Richtung verdreht sein.The lock is shaped so that the tape originates from the lock approximately in the feed direction and that the tape opening 25 is approximately parallel to this direction. Exact parallelism is not necessary. Rather, when looking at FIG. 3, the band opening could also be rotated a little counterclockwise with respect to the direction shown.

Wenn das Schloß 8 seine Endposition in der Schloßhalterung erreicht hat, befindet sich das freie Ende der Bandzunge etwa am Ende 22 der Umschlingungsführung oder zwischen diesem Ende und dem Bandschloß 8. Die Bandspitze muß nun in die Bandöffnung 25 des Schlosses eingeführt werden. Dies geschieht dadurch, daß der Zangenteil 15 aus der in Fig. 2 dargestellten Umschlingungsstellung in Pfeilrichtung 26 weitergeschwenkt wird. Dadurch verkürzt sich die in der Umschlingungsführung zur Aufnahme der Bandzunge 7 zur Verfügung stehende Strecke. Da das Schloß 8 währenddessen festgehalten ist, muß sich die Bandspitze weiter bewegen. Wenn der Zangenteil 15 seine in Fig. 3 dargestellte Endstellung erreicht hat, ist das freie Ende der Bandzunge 7 durch die Bandöffnung 25 hindurchgetreten und hat den Spalt zwischen zwei währenddessen in Pfeilrichtung rotierenden Spannrollen 28, 29 erreicht, die das Bandende erfassen und spannen.When the lock 8 has reached its end position in the lock holder, the free end of the strap tongue is located approximately at the end 22 of the loop guide or between this end and the strap lock 8. The strap tip must now be inserted into the strap opening 25 of the lock. This is done in that the pliers part 15 is pivoted further from the wrap position shown in Fig. 2 in the direction of arrow 26. This shortens the distance available in the loop guide for receiving the band tongue 7. Since the lock 8 is held in the meantime, the tape tip must continue to move. When the pliers part 15 has reached its end position shown in FIG. 3, the free end of the band tongue 7 has passed through the band opening 25 and has reached the gap between two tensioning rollers 28, 29 rotating in the direction of the arrow, which grip and tension the band end.

Gemäß Fig. 3 wird der Spannvorgang solange fortgesetzt, bis die gewünschte Spannung in der Bandzunge 7 erreicht und der zu bindende Gegenstand (Kabel 19) fest umschnürt ist.According to FIG. 3, the tensioning process is continued until the desired tension in the strap tongue 7 is reached and the object (cable 19) to be tied is securely tied.

Zum Abschneiden des überstehenden Bandendes 30 ist eine Klinge 31 vorgesehen, die in ihrer Längsrichtung geführt ist und mit nicht dargestellten, herkömmlichen Antriebs- und Steuerungsmittel in Verbindung steht. Zur Durchführung des Schnitts wird sie in Fig. 3 nach links bewegt, so daß ihre Schneide die Bandzunge durchtrennt. Dabei dient ihr der Sporn 21 als Widerlager. Dafür kann es genügen, wenn der Sporn in seinem Widerlagerbereich - wie dargestellt - eine glatte Anlagefläche für das Band bildet. Stattdessen kann an dieser Stelle aber auch eine Einsenkung in die Oberfläche des Sporns vorgesehen sein, die eine mit der Klinge zusammenwirkende Gegenschneide oder Schneidkante bildet.To cut off the protruding band end 30, a blade 31 is provided, which is guided in its longitudinal direction and is connected to conventional drive and control means, not shown. To carry out the cut, it is moved to the left in FIG. 3, so that its cutting edge cuts through the strip tongue. The spur 21 serves as an abutment. It can be sufficient for the spur to form a smooth contact surface for the belt in its abutment area, as shown. Instead, a depression can also be provided at this point in the surface of the spur, which forms a counter-cutting edge or cutting edge which interacts with the blade.

Bei der Positionierung des Schlosses 8 in der Schloßhalterung durch den gehäusefesten Teil 23, den Sporn 21, den mit dem Sporn verbundenen Teil 35 sowie den Schieberkopf 9 spielen seitlich vorspringende Bereiche des Schlosses eine Rolle, wie beispielsweise der Teller 34, der mit dem Zapfen 33 zu Befestigungsorganen gehört, die am Schloß zur Befestigung an einer Halteplatte, beispielsweise einer Schalttafel, dienen sollen. Dem Teller 34 sind hinterschnittene Flächen am Schieberkopf 9 und an dem Teil 35 zugeordnet, die vor den Teller (bezogen auf die Entnahmerichtung) greifen.When the lock 8 is positioned in the lock holder by the part 23 fixed to the housing, the spur 21, the part 35 connected to the spur and the slide head 9, laterally projecting regions of the lock play a role, such as, for example, the plate 34 which is connected to the pin 33 belongs to fasteners that are to be used on the lock for fastening to a holding plate, for example a control panel. Undercut surfaces on the slide head 9 and on the part 35 are assigned to the plate 34 and engage in front of the plate (in relation to the removal direction).

Zu den seitlich vorspringenden Teilen des Schlosses gehört auch das jenseits des Schlosses überstehende freie Bandende 30, soweit es nicht von der Klinge 31 entfernt wird. Vor dieses überstehende Bandende greift der Sporn 21.The laterally projecting parts of the lock also include the free band end 30 which projects beyond the lock, provided that it is not removed from the blade 31. The spur 21 engages in front of this protruding band end.

Alle Halterungsteile, die vor einen seitlich vorspringenden Bereich des Schlosses 8 fassen, müssen nach dem Bindevorgang entfernt werden, damit das Schloß entnommen werden kann. Beim Schieberkopf 9 geschieht dies dadurch, daß er zurückgezogen wird. Hinsichtlich der Teile 21, 35 geschieht dies dadurch, daß sie starr mit dem Zangenteil 16 verbunden sind und daher bei dessen Verschwenkung um den Punkt 18 einen Kreisbogen beschreiben, der in Fig. 1 etwa nach links unten gerichtet ist, also sowohl seitlich als auch in Entnahmerichtung. Dadurch wirkt auf den Gegenstand eine Bewegung in Entnahmerichtung in der Art eines Auswerfers. Auch vergrößert sich dadurch die Öffnung, durch die hindurch die vorstehenden Teile des Schlosses entnommen werden können, so daß die Entnahme erleichtert wird.All mounting parts that reach in front of a laterally projecting area of the lock 8 must be removed after the binding process so that the lock can be removed. In the slide head 9, this is done by pulling it back. With regard to the parts 21, 35, this is done in that they are rigidly connected to the pliers part 16 and therefore, when pivoted about the point 18, describe a circular arc which is directed approximately to the bottom left in FIG. 1, that is to say both laterally and in Withdrawal direction. As a result, a movement in the removal direction acts on the object in the manner of an ejector. This also increases the opening through which the protruding parts of the lock can be removed, so that removal is facilitated.
