Abstract

The clip has two relatively movable jaws (2,3) joined by an axle (4) and which clamp the object and are connected to a closure arrangement (7) applying closure pressure pressing the jaws of the clip together. The closure arrangement is movable between a release and closed position. The closure arrangement has two spaced apart facing clamping elements (8,9) resting in a closed position against the non-facing outer sides (17,18) of the clip jaws. The clamping elements are attached to a bracket (10,11) which has a follow-up roller. When closed, the clamping elements each fit into a recess (19) on the outside of each jaw.

Description

Die vorliegende Erfindung betrifft eine Klammer zum Halten flächiger Gegenstände, insbesondere flexibler Gegenstände wie ein- und mehrblättrige Druckereiprodukte, gemäss Oberbegriff des Anspruches 1.The present invention relates to a clamp for holding flat objects, in particular flexible objects such as single-page and multi-page printed products, according to the preamble of claim 1.

Eine Klammer dieser Art ist aus der CH-A-636 824 bzw. der entsprechenden US-A-4,307,801 bekannt. Diese Klammer weist zwei Klammerbacken auf, die um eine gemeinsame Achse schwenkbar in einem Halter gelagert sind. Eine Schliessfeder wirkt in Schliessrichtung auf die Klammerbacken und hält diese in einer Klemmstellung. Zum Oeffnen der Klammer wird jeweils die eine Klammerbacke durch Krafteinwirkung auf einen mit dieser Klammerbacke fest verbundenen Oeffnungshebel entgegen der Wirkung der Schliessfeder von der andern Klammerbacke weggeschwenkt. Um die Klammer öffnen zu können, muss also jedesmal die Kraft der Schliessfeder überwunden werden.A clip of this type is known from CH-A-636 824 and the corresponding US-A-4,307,801. This clamp has two clamp jaws which are pivotally mounted in a holder about a common axis. A closing spring acts on the clamping jaws in the closing direction and holds them in a clamping position. To open the clamp, one clamp jaw is pivoted away from the other clamp jaw against the action of the closing spring by the force acting on an opening lever firmly connected to this clamp jaw. In order to be able to open the clamp, the force of the closing spring must be overcome each time.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, eine Klammer der eingangs genannten Art zu schaffen, bei der die Klemmbacken in ihrer Klemmstellung den erfassten Gegenstand sicher festklemmen, die Klammer aber auf einfache Weise geöffnet werden kann.The present invention has for its object to provide a clip of the type mentioned, in which the jaws securely clamp the detected object in its clamping position, but the clip can be opened in a simple manner.

Diese Aufgabe wird mit einer Klammer mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with a bracket with the features of claim 1.

Die Schliesseinrichtung sorgt in ihrer Schliessstellung dafür, dass die Klammerbacken zur Erzielung einer genügend starken Klemmwirkung gegeneinander gedrückt werden. Beim Verbringen der Schliesseinrichtung in die Freigabestellung verschwinden die auf die Klammerbacken einwirkenden Schliesskräfte und die Klammerbacken können sich voneinander weg bewegen und den erfassten Gegenstand freigeben.In its closed position, the locking device ensures that the clamping jaws are pressed against one another to achieve a sufficiently strong clamping effect. When the closing device is moved into the release position, the closing forces acting on the clamping jaws disappear and the clamping jaws can become loose move away from each other and release the detected object.

Bevorzugte Weiterausgestaltungen der erfindungsgemässen Klammer bilden Gegenstand der abhängigen Ansprüche.Preferred further developments of the clip according to the invention form the subject of the dependent claims.

Die erfindungsgemässe Klammer eignet sich für den Einsatz in einer Transportvorrichtung für flächige Gegenstände, bei der die Klammern an einem umlaufend angetriebenen Zugorgan angebracht sind und so entlang einer Transportbahn bewegt werden.The clip according to the invention is suitable for use in a transport device for flat objects, in which the clips are attached to a rotating drive element and are thus moved along a transport path.

Anhand der Fig. 1 bis 5 wird nachfolgend der Aufbau und die Wirkungsweise der erfindungsgemässen Klammer erläutert.The construction and the mode of operation of the clip according to the invention are explained below with reference to FIGS. 1 to 5.

Die Klammer 1 weist zwei Klammerbacken 2, 3 auf, die aus einem biegesteifen Material, vorzugsweise aus einem geeigneten Kunststoff, bestehen. Die beiden Klammerbacken 2, 3 sind um eine gemeinsame Achse 4 schwenkbar gelagert. Hiezu ist die Klammerbacke 2 mit Laschen 5 und die Klammerbacke 3 mit Laschen 6 versehen, die die Achse 4 umgreifen und in deren Längsrichtung abwechselnd angeordnet sind, wie das aus den Fig. 1, 3 und 5 deutlich hervorgeht. Die Klammerbacken 2, 3 werden in ihrer in den Fig. 1 und 2 gezeigten Klemmstellung mittels einer Schliesseinrichtung 7 gegeneinander gedrückt. Diese Schliesseinrichtung 7 ist in den Fig. 1 und 2 in ihrer Schliessstellung und in den Fig. 3 und 4 in ihrer Freigabestellung gezeigt.The clamp 1 has two clamp jaws 2, 3, which consist of a rigid material, preferably of a suitable plastic. The two clamp jaws 2, 3 are pivotally mounted about a common axis 4. For this purpose, the clamp jaw 2 is provided with tabs 5 and the clamp jaw 3 with tabs 6, which grip around the axis 4 and are arranged alternately in the longitudinal direction thereof, as can be clearly seen from FIGS. 1, 3 and 5. The clamping jaws 2, 3 are pressed against one another in their clamping position shown in FIGS. 1 and 2 by means of a locking device 7. This locking device 7 is shown in FIGS. 1 and 2 in its closed position and in FIGS. 3 and 4 in its release position.

Die Schliesseinrichtung 7 weist zwei sich in einem Abstand a (Fig. 2) gegenüberliegende Klemmkörper 8, 9 auf, zwischen denen sich die Klammerbacken 2, 3 erstrecken. Jeder Klemmkörper 8, 9 ist vorzugsweise drehbar auf einem biegesteifen Tragarm 10 bzw. 11 befestigt. An ihrem einen Ende sind die beiden Tragarme 10, 11 über ein Verbindungsstück 12 miteinander verbunden. Von diesem Verbindungsstück 12 ragt ein Lagerbolzen 13 weg, auf dem eine Steuerrolle 14 gelagert ist. Letztere kann drehbar oder fest mit dem Lagerbolzen 13 verbunden sein. Am gegenüberliegenden Ende sind die Tragarme 10, 11 an einer Schwenkachse 15 befestigt, die schwenkbar in einem Lagerkörper 16 gelagert ist. Letzterer sitzt drehbar auf der Achse 4, so dass die Schliesseinrichtung 7 sich mit den Klammerbacken 2, 3 verschwenken kann. Die Tragarme 10, 11, das Verbindungsstück 12 und die Schwenkachse 15 bilden einen Bügel.The locking device 7 has two clamping bodies 8, 9 located at a distance a (FIG. 2), between which the clamping jaws 2, 3 extend. Each clamping body 8, 9 is preferably rotatable on one rigid support arm 10 or 11 attached. At one end, the two support arms 10, 11 are connected to one another via a connecting piece 12. A bearing pin 13 on which a control roller 14 is mounted protrudes from this connecting piece 12. The latter can be rotatably or fixedly connected to the bearing pin 13. At the opposite end, the support arms 10, 11 are attached to a pivot axis 15 which is pivotally mounted in a bearing body 16. The latter is rotatably seated on the axis 4, so that the locking device 7 can pivot with the clamp jaws 2, 3. The support arms 10, 11, the connector 12 and the pivot axis 15 form a bracket.

Auf ihrer aussenliegenden Seite 17, 18 sind die Klammerbacken 2, 3 an ihrem der Achse 4 benachbarten Ende mit Rastvertiefungen 19, 20 für die Klemmkörper 8, 9 versehen. Diese Rastvertiefungen 19, 20 werden gegen die Achse 4 hin von einer Rastnase 21 bzw. 22 in Form eines Wulstes begrenzt. Der Abstand b (Fig. 2) zwischen den äussersten Stellen der Rastnasen 21, 22 ist dabei grösser als der Abstand a zwischen den Klemmkörpern 8, 9.On their outer side 17, 18, the clamping jaws 2, 3 are provided with locking recesses 19, 20 for the clamping bodies 8, 9 at their end adjacent to the axis 4. These locking recesses 19, 20 are delimited against the axis 4 by a locking lug 21 or 22 in the form of a bead. The distance b (FIG. 2) between the outermost points of the locking lugs 21, 22 is greater than the distance a between the clamping bodies 8, 9.

Die Funktionsweise der Klammer 1 ist wie folgt:
Ist die Schliesseinrichtung 7 wie in den Fig. 3 und 4 gezeigt in die Freigabestellung hochgeschwenkt, in der die Klemmkörper 8, 9 sich auf der bezüglich der Rastnasen 21, 22 gegenüberliegenden Seite der Rastvertiefungen 19, 20 befinden, so können sich die Klammerbacken 2, 3 um die Achse 4 voneinander wegschwenken und die Offenstellung einnehmen (Fig. 4). Dabei ist der Oeffnungswinkel durch die beiden Klemmkörper 8, 9 gegeben. Zum Schliessen der Klammer 1 und Aufbringen einer Klemmkraft wird die Schliesseinrichtung 7 von der Freigabestellung nach unten in die Schliessstellung verschwenkt. Dieser Zustand ist in den Fig. 1 und 2 gezeigt. Im Zuge dieser Verschwenkung in die Schliessstellung müssen unter Aufbringung einer gewissen Kraft zuerst die Rastnasen 21, 22 von den Klemmkörpern 8, 9 überfahren werden, worauf letztere dann in die Rastvertiefungen 19, 20 eingreifen. Wie die Fig. 2 zeigt sind die Klammerbacken 2, 3 so ausgebildet, dass sich deren Enden 2a, 3a berühren, während die Klammerbacken 2, 3 im Bereich der Rastvertiefungen voneinander beabstandet sind. Anders ausgedrückt sind die Klammerbacken 2, 3 von der Achse 4 her bis zu den Enden 2a, 3a hin leicht gewölbt. Jeder der beiden ein einem festen Abstand a voneinander angeordneten Klemmkörper 8, 9 übt in Schliessstellung der Schliesseinrichtung 7 auf die zugeordnete Klammerbacke 2, 3 eine Schliesskraft F1 bzw. F2 (Fig. 2) aus. Die beiden Schliesskräfte F1, F2 wirken einander entgegengesetzt jeweils auf die Aussenseite 17 bzw. 18 der entsprechenden Klammerbacke 2 bzw. 3.
The operation of the bracket 1 is as follows:
3 and 4 is pivoted up into the release position in which the clamping bodies 8, 9 are located on the side of the locking recesses 19, 20 opposite the locking lugs 21, 22, the clamping jaws 2, 3 swivel away from each other about axis 4 and assume the open position (Fig. 4). The opening angle is given by the two clamping bodies 8, 9. To close the clamp 1 and apply a clamping force, the locking device 7 is moved downward from the release position pivoted into the closed position. This state is shown in FIGS. 1 and 2. In the course of this pivoting into the closed position, the locking lugs 21, 22 must first be run over by the clamping bodies 8, 9 with the application of a certain force, after which the latter then engage in the locking recesses 19, 20. As shown in FIG. 2, the clamp jaws 2, 3 are designed such that their ends 2a, 3a touch, while the clamp jaws 2, 3 are spaced apart from one another in the region of the latching depressions. In other words, the clamp jaws 2, 3 are slightly curved from the axis 4 to the ends 2a, 3a. Each of the two clamping bodies 8, 9 arranged at a fixed distance a from one another exerts a closing force F1 or F2 (FIG. 2) on the associated clamping jaw 2, 3 in the closed position of the closing device 7. The two closing forces F1, F2 act opposite to each other on the outside 17 and 18 of the corresponding clamp jaw 2 and 3, respectively.

In Fig. 6 ist in einer der Fig. 4 entsprechenden Darstellung eine andere Ausführungsform einer Klammer 1 in Offenstellung gezeigt. Diese Ausführungsform der Klammer 1 unterscheidet sich von derjenigen gemäss den Fig. 1 bis 5 nur dadurch, dass jede Klammerbacke 2, 3 mit einem Betätigungshebel verbunden ist, nämlich die Klammerbacke 2 mit einem Betätigungshebel 24 und die Klammerbacke 3 mit einem Betätigungshebel 25. Die Betätigungshebel 24, 25 sind schwenkbar auf der Achse 4 gelagert und tragen an ihrem freien Ende eine Steuerrolle 26 bzw. 27. Strichpunktiert sind in der Fig. 6 Steuerkurven 28 bzw. 29 angedeutet, die auf die zugeordneten Steuerrollen 26 bzw. 27 einwirken. Ueber diese Betätigungshebel 24, 25 und die mit den Steuerkulissen 28, 29 zusammenwirkenden Steuerrollen 26, 27 kann die Schwenkbewegung der Klammerbacken 2 und 3 von der Offenstellung in die Klemmstellung und bei sich in Freigabestellung befindlicher Schliesseinrichtung 7 auch von der Klemmstellung in die Offenstellung gesteuert werden. Bei geschlossener Klammer 1, d.h. bei in Klemmstellung verriegelten Klammerbacken 2, 3, kann mittels der Betätigungshebel 24, 25 die Klammer 1 als Einheit um die Achse 4 verschwenkt werden.Another embodiment of a clamp 1 in the open position is shown in FIG. 6 in a representation corresponding to FIG. 4. This embodiment of the clamp 1 differs from that according to FIGS. 1 to 5 only in that each clamp jaw 2, 3 is connected to an actuating lever, namely the clamp jaw 2 with an actuating lever 24 and the clamp jaw 3 with an actuating lever 25. The actuating levers 24, 25 are pivotally mounted on the axis 4 and carry a control roller 26 or 27 at their free end. Dashed lines are shown in FIG. 6, control cams 28 and 29 which act on the associated control rollers 26 and 27. Via these actuating levers 24, 25 and the control rollers 26, 27, which interact with the control links 28, 29, the pivoting movement of the clamping jaws 2 and 3 can be changed from the open position into the Clamping position and when the locking device 7 is in the release position can also be controlled from the clamping position into the open position. When the clamp 1 is closed, ie when the clamp jaws 2, 3 are locked in the clamping position, the clamp 1 can be pivoted as a unit about the axis 4 by means of the actuating levers 24, 25.

Es ist selbstverständlich möglich, die Klammerbacken 2, 3 mittels der zugeordneten Betätigungshebel 24, 25 einzeln zu steuern.It is of course possible to individually control the clamping jaws 2, 3 by means of the associated actuating levers 24, 25.

In Fig. 6 ist weiter angedeutet, dass die Klammer 1, sei sie nun von der in Fig. 6 gezeigten oder von der in den Fig. 1 bis 5 gezeigten Konstruktion, über eine Halterung 30 an einem in Fig. 6 nur schematisch angedeuteten Zugorgan 31 befestigt sein kann, das in einem Führungskanal 32 geführt umlaufend angetrieben ist. Die Klammern 1 bilden auf diese Weise Teil einer Transportvorrichtung, wie sie anhand der Fig. 7 noch näher erläutert werden wird.In FIG. 6 it is further indicated that the clip 1, be it of the construction shown in FIG. 6 or of the construction shown in FIGS. 1 to 5, via a holder 30 on a pulling element which is only schematically indicated in FIG. 6 31 can be fastened, which is driven in a guided manner in a guide channel 32. In this way, the clamps 1 form part of a transport device, as will be explained in more detail with reference to FIG. 7.

Zum Verschwenken der durch die Schliesseinrichtung 7 freigegebenen Klammerbacken 2, 3 von der Klemm- in die Offenstellung kann auch eine Druckfeder 33 verwendet werden, die zwischen den Klammerbacken 2, 3 angeordnet ist und in Fig. 6 schematisch angedeutet ist. Durch die Druckfeder 33 werden die Klammerbacken 2, 3 in ihrer Offenstellung gehalten. Diese Druckfeder 33 kann auch bei einer Klammer 1, wie sie in den Fig. 1 - 5 gezeigt ist, eingesetzt werden.To pivot the clamping jaws 2, 3 released by the locking device 7 from the clamping into the open position, a compression spring 33 can also be used, which is arranged between the clamping jaws 2, 3 and is indicated schematically in FIG. 6. The clamp jaws 2, 3 are held in their open position by the compression spring 33. This compression spring 33 can also be used with a clamp 1, as shown in FIGS. 1-5.

In Fig. 7 ist ein Abschnitt der bereits erwähnten Transportvorrichtung 34 gezeigt. Mittels der Halterungen 30 sind in regelmässigen Abständen Klammern 1 am Zugorgan 31 befestigt, das in Richtung des Pfeiles B angetrieben ist. Die Transporteinrichtung 34 dient zum Fördern von Druckereierzeugnissen 35 (z.B. gefaltete Druckbogen) zu einer Abgabestelle Z. An dieser Abgabestelle Z befindet sich ein Ablagetisch 36, dem ein ansteigender Führungsabschnitt 36a vorgeschaltet ist.FIG. 7 shows a section of the transport device 34 already mentioned. The brackets 30 are brackets 1 on the tension member at regular intervals 31 attached, which is driven in the direction of arrow B. The transport device 34 is used to convey printed products 35 (eg folded printed sheets) to a delivery point Z. At this delivery point Z there is a delivery table 36 which is preceded by a rising guide section 36a.

Wie aus Fig. 7 ersichtlich ist, werden die durch die geschlossenen Klammern 1 festgehaltenen Druckereierzeugnisse 35 hängend zur Abgabestelle Z geführt. Die unteren Endbereiche 35a der Druckereierzeugnisse 35 laufen auf den ansteigenden Führungsabschnitt 36a auf, was zur Folge hat, dass die Druckereierzeugnisse 35 in eine nach rückwärts abfallende Schräglage gezwungen werden. Oberhalb des Ablagetisches 36 ist eine ortsfeste Oeffnungskulisse 37 angeordnet, die in Förderrichtung B gesehen ansteigt. Die Steuerrollen 14 der Schliesseinrichtungen 7 laufen auf diese Oeffnungskulisse 37 auf, was zur Folge hat, dass die Schliesseinrichtung 7 aus der Schliessstellung in die Freigabestellung hochgeschwenkt werden. Damit werden die Klammerbacken 2, 3 freigegeben und können sich voneinander weg bewegen. Die Druckereierzeugnisse 35 fallen nach unten und legen sich dabei jeweils dachziegelartig auf das vorangehende Druckereierzeugnis 35 ab. Die so auf dem Ablagetisch 36 gebildete Schuppenformation S wird mittels eines nicht näher dargestellten Wegförderers in Richtung des Pfeiles C weggeführt. Die offenen Klammern 1 laufen in Hängelage weiter zu einer nicht dargestellten Aufnahmestation, in der sie wieder ein Druckereierzeugnis 35 aufnehmen. Dabei wird die Schliesseinrichtung 7 ebenfalls mittels einer Kulisse oder dgl. von der Freigabestellung in die Schliessstellung zurückverschwenkt, sobald das wegzutransportierende Druckereierzeugnis 35 zwischen die Klammerbacken 2, 3 eingeschoben ist.As can be seen from FIG. 7, the printed products 35 held in place by the closed clamps 1 are guided to the delivery point Z in a hanging manner. The lower end regions 35a of the printed products 35 run onto the rising guide section 36a, with the result that the printed products 35 are forced into a backward sloping position. A stationary opening gate 37 is arranged above the storage table 36 and rises as seen in the conveying direction B. The control rollers 14 of the locking devices 7 run onto this opening link 37, which has the consequence that the locking device 7 is pivoted up from the closed position into the release position. Thus the jaws 2, 3 are released and can move away from each other. The printed products 35 fall down and in each case lay down like roof tiles on the preceding printed product 35. The scale formation S thus formed on the storage table 36 is carried away in the direction of the arrow C by means of a non-illustrated conveyor. The open brackets 1 continue in a hanging position to a receiving station, not shown, in which they again receive a printed product 35. The locking device 7 is also pivoted back from the release position into the closed position by means of a backdrop or the like as soon as the printed product 35 to be transported is inserted between the clamping jaws 2, 3.

Anhand der Fig. 7 lassen sich auch Abwandlungen in der Konstruktion der Klammern 1 erläutern.7, modifications in the construction of the brackets 1 can also be explained.

Wird der Lagerkörper 16 an der Halterung 30 befestigt, so dass sich die Schliesseinrichtung 7 auf der Achse 4 nicht mehr drehen kann, so ist die Lage der Klammern 1 sowohl im offenen wie im geschlossenen Zustand gegeben. In dieser gegebenen Lage können sich die Klammern 1 in vertikaler Richtung erstrecken oder gegenüber der Vertikalen unter einem Winkel schräggestellt sein.If the bearing body 16 is fastened to the holder 30 so that the locking device 7 can no longer rotate on the axis 4, the position of the clamps 1 is given both in the open and in the closed state. In this given position, the clamps 1 can extend in the vertical direction or be inclined at an angle with respect to the vertical.

Statt wie beschrieben beide Klammerbacken 2 und 3 schwenkbar auf der Achse 4 zu lagern ist es auch möglich, eine Klammerbacke 2 oder 3 in ihrer Lage zu fixieren und nur die andere Klammerbacke schwenkbar zu lagern. Eine solche Ausführungsform ist in Fig. 7 durch die mit 1' bezeichnete Klammer dargestellt. Dabei nimmt die Klammerbacke 3 eine fixe Stellung ein, während die andere Klammerbacke 2 schwenkbar gelagert ist.Instead of pivotally mounting both clamp jaws 2 and 3 on axis 4, as described, it is also possible to fix a clamp jaw 2 or 3 in its position and to only pivotally mount the other clamp jaw. Such an embodiment is shown in FIG. 7 by the bracket denoted by 1 '. The clamp jaw 3 assumes a fixed position, while the other clamp jaw 2 is pivotally mounted.

In Fig. 8 ist - ausgehend von einer Transporteinrichtung 34, wie sie in Fig. 7 gezeigt ist - eine Pufferstation 38 gezeigt, in der eine Anzahl von geschlossenen Klammern 1 so zusammengeschoben sind, dass sie aneinander anstossen. Die von den Klammern 1 festgehaltenen Druckereiprodukte sind nicht gezeigt. Für eine solche Pufferung der Klammern 1 müssen letztere lösbar mit dem Zugorgan 31 verbunden sein. Die am Zugorgan 31 festgeklemmten Klammern 1 werden zur Pufferstation 38 gebracht. Beim Auftreffen auf die vorangehende Klammer wird dann die Verbindung zum Zugorgan 31 gelöst. Zum Entleeren der Pufferstation 38 werden dann die Klammern 1 nacheinander wieder an das Zugorgan 31 angekoppelt, das dabei entweder in Förderrichtung B oder in der entgegengesetzten Richtung angetrieben sein kann.In FIG. 8, starting from a transport device 34 as shown in FIG. 7, a buffer station 38 is shown, in which a number of closed clamps 1 are pushed together so that they abut one another. The printed products held by the brackets 1 are not shown. For such a buffering of the clamps 1, the clamps 1 must be releasably connected to the tension member 31. The clamps 1 clamped on the tension member 31 are brought to the buffer station 38. When hitting the preceding bracket, the connection to the tension member 31 is then released. To empty the buffer station 38, the clamps 1 are then successively coupled again to the traction element 31, which can be driven either in the conveying direction B or in the opposite direction.

Aus dieser Fig. 8 ist ersichtlich, dass wegen der konstruktiv bedingten geringen Breite der Klammern 1 diese in der Pufferstation 38 wenig Raum beanspruchen.It can be seen from this FIG. 8 that, due to the constructionally small width of the clamps 1, they take up little space in the buffer station 38.

Die in den Fig. 9-11 in Seitenansicht und Draufsicht gezeigte dritte Ausführungsform einer erfindungsgemässen Klammer 50 weist ebenfalls zwei Klammerbacken 51, 52 auf, die vorzugsweise aus einem federelastischen Material, z.B. aus Federstahl, bestehen. Die eine Klammberbacke 51 ist an einem Klammerkörper 53 befestigt und ist somit fix. Am Klammerkörper 53 ist eine Halterung 54 angebracht, in der eine Achse 55 gehalten ist. Auf dieser Achse 55 ist die bewegliche Klammerbacke 52 schwenkbar gelagert. Zu diesem Zwecke weist die Klammerbacke 52 zwei seitliche, hochgebogene Laschen 56 auf, die von der Achse 55 durchdrungen werden. Die bewegliche Klammerbacke 52 wird in ihrer in Fig. 10 gezeigten Klemmstellung mittels einer Schliesseinrichtung 57 gegen die fixe Klammerbacke 51 gedrückt. Die Schliesseinrichtung 57 ist in Fig. 10 in ihrer Schliessstellung und in der Fig. 9 in ihrer Freigabestellung gezeigt. Die Fig. 9 zeigt die Klammer 50 in Offenstellung.The third embodiment of a clamp 50 according to the invention shown in side view and plan view in FIGS. 9-11 also has two clamp jaws 51, 52, which are preferably made of a resilient material, e.g. made of spring steel. One clamp jaw 51 is fastened to a clamp body 53 and is therefore fixed. A bracket 54, in which an axis 55 is held, is attached to the clamp body 53. The movable clamp jaw 52 is pivotably mounted on this axis 55. For this purpose, the clamping jaw 52 has two lateral, bent-up tabs 56, which are penetrated by the axis 55. In its clamped position shown in FIG. 10, the movable clamp jaw 52 is pressed against the fixed clamp jaw 51 by means of a locking device 57. The locking device 57 is shown in its closed position in FIG. 10 and in its release position in FIG. 9. 9 shows the clamp 50 in the open position.

Die Schliesseinrichtung 57 weist eine Klemmrolle 58 auf, die vorzugsweise drehbar auf einem Tragbügel 59 angeordnet ist. Mit dem Tragbügel 59 ist ein Betätigungshebel 60 verbunden, der an seinem freien Ende eine Steuerrolle 61 aufweist. An ihrer aussenliegenden Seite 62 ist die bewegliche Klammerbacke 52 mit einer Rastvertiefung 63 für die Klemmrolle 58 versehen. Mittels Anstanzen ist in der fixen Klammerbacke 51 eine federnde Zunge 64 ausgebildet, die in ihrer in der Fig. 9 gezeigten entspannten Stellung von der Klammerbacke 51 gegen die bewegliche Klammerbacke 52 hin vorsteht. Die federnde Zunge 64 greift mit ihrem freien Ende an der beweglichen Klammerbacke 52 an und hält diese offen.The locking device 57 has a clamping roller 58, which is preferably rotatably arranged on a support bracket 59. An actuating lever 60 is connected to the support bracket 59 and has a control roller 61 at its free end. On its outer side 62, the movable clamp jaw 52 is provided with a locking recess 63 for the pinch roller 58. By means of punching, a resilient tongue 64 is formed in the fixed clamp jaw 51, which in its relaxed position shown in FIG. 9 protrudes from the clamp jaw 51 against the movable clamp jaw 52. The resilient tongue 64 engages with her free end on the movable clamp jaw 52 and keeps it open.

Die Funktionsweise der Klammer 50 ist wie folgt:
Befindet sich die Schliesseinrichtung 57 in der in Fig. 9 gezeigten Freigabestellung, so kann die bewegliche Klammerbacke 52 durch die federnde Zunge 64 von der fixen Klammerbacke 51 weggeschwenkt werden. Die Klammer 50 befindet sich in der Offenstellung. Läuft bei geöffneter Klammer 50 während deren Bewegung in Richtung des Pfeiles D die Steuerrolle 61 auf die in Fig. 9 nur schematisch dargestellte Schliesskulisse 65 auf, so wird die Schliesseinrichtung 57 von der Freigabestellung in die Schliessstellung verschwenkt. Anders ausgedrückt wird zum Schliessen der offenen Klammer 50 der Tragbügel 59 mit der Klemmrolle 58 in Richtung des Pfeiles E (Fig. 9) verschwenkt. Während dieser Verschwenkbewegung drückt die auf die aussenliegende Seite 62 der Klammerbacke 52 einwirkende Klemmrolle 58 die bewegliche Klammerbacke 52 gegen die fixe Klammerbacke 51. In der in Fig. 10 gezeigten Klemmstellung der Klammer 50 rastet die Klemmrolle 58 in die Rastvertiefung 63 ein. In dieser Klemmstellung der Klammer 50 klemmen die beiden Klammerbacken 51, 52 mit ihren Enden 51a und 52a das zu transportierende Druckereierzeugnis fest. In der Schliessstellung der Schliesseinrichtung 57, in der wie erwähnt die Klemmrolle 58 in die Rastvertiefung 63 eingreift, ist die federnde Zunge 64 gespannt. Die Schliesseinrichtung 57 nimmt in ihrer Schliessstellung eine stabile Lage ein, was bedeutet, dass zum Verriegeln der beiden Klammerbacken 51, 52 in der Klemmstellung keine zusätzlichen von aussen auf die Schliesseinrichtung 57 einwirkende Mittel nötig sind.
The operation of the bracket 50 is as follows:
If the locking device 57 is in the release position shown in FIG. 9, the movable clamp jaw 52 can be pivoted away from the fixed clamp jaw 51 by the resilient tongue 64. The bracket 50 is in the open position. If, when the clamp 50 is open, the control roller 61 runs onto the closing link 65, which is only shown schematically in FIG. 9, during its movement in the direction of the arrow D, the closing device 57 is pivoted from the release position into the closed position. In other words, to close the open bracket 50, the support bracket 59 is pivoted with the pinch roller 58 in the direction of the arrow E (FIG. 9). During this pivoting movement, the clamping roller 58 acting on the outer side 62 of the clamping jaw 52 presses the movable clamping jaw 52 against the fixed clamping jaw 51. In the clamping position of the clamp 50 shown in FIG. 10, the clamping roller 58 engages in the locking recess 63. In this clamping position of the clamp 50, the two clamp jaws 51, 52 clamp with their ends 51a and 52a the printed product to be transported. In the closed position of the locking device 57, in which, as mentioned, the clamping roller 58 engages in the locking recess 63, the resilient tongue 64 is tensioned. The locking device 57 assumes a stable position in its closed position, which means that no additional means acting on the locking device 57 from the outside are required to lock the two clamping jaws 51, 52 in the clamping position.

Zum Oeffnen der geschlossenen Klammer 50 dient eine in Fig. 10 nur schematisch dargestellte Oeffnungskulisse 66, auf die die Steuerrolle 61 aufläuft. Dadurch wird der Tragbügel 59 mit der Klemmrolle 58 in Richtung des Pfeiles F in die Freigabestellung zurück verschwenkt. Die bewegliche Klammerbacke 52 wird durch die federnde Zunge 64 von der fixen Klammerbacke 51 weggedrückt.An opening link 66, which is only shown schematically in FIG. 10 and on which the control roller 61 runs, serves to open the closed clamp 50. Characterized the support bracket 59 is pivoted back with the pinch roller 58 in the direction of arrow F in the release position. The movable clamp jaw 52 is pressed away from the fixed clamp jaw 51 by the resilient tongue 64.

Die erfindungsgemässe Klammer 1 bzw. 50 hat den weitern Vorteil, dass sie von verhältnismässig einfacher und leichter Konstruktion ist. Das Verriegeln der Klammerbacken 2, 3 bzw. 51, 52 in ihrer Klemmstellung erfolgt rasch und ohne allzugrossen Kraftaufwand durch eine kurze Bewegung der Schliesseinrichtung 7 bzw. 57 von der Freigabe- in die Schliessstellung. Dies trifft sinngemäss natürlich auch auf den Oeffnungsvorgang zu.The clip 1 or 50 according to the invention has the further advantage that it is of relatively simple and light construction. The clamping jaws 2, 3 and 51, 52 are locked in their clamping position quickly and without excessive force by a short movement of the locking device 7 or 57 from the release into the closed position. Naturally, this also applies to the opening process.

Statt die Schliesseinrichtung 7 durch Verschwenken von der Freigabestellung in die Schliessstellung und umgekehrt zu bringen, ist es auch möglich, die Schliesseinrichtung 7 so auszubilden, dass sie durch eine translatorische Bewegung von der Schliess- in die Freigabestellung und umgekehrt verbracht werden kann.Instead of bringing the locking device 7 by pivoting it from the release position into the closed position and vice versa, it is also possible to design the locking device 7 in such a way that it can be moved from the locking position into the release position and vice versa by a translational movement.

Die erfindungsgemässe Klammer 1 bzw. 50 kann auch zum Halten sowohl von andern flexiblen Gegenständen als Druckereierzeugnissen wie auch von steifen flächigen Gegenständen, wie z.B. solchen aus Karton, dienen.The clamp 1 or 50 according to the invention can also be used to hold both flexible objects other than printed products and rigid flat objects, such as e.g. those made of cardboard.
