Description

Die Erfindung betrifft eine Einrichtung zum lösbaren Heften und Verklammern von Papierbögen o.dgl., mit einer als im Querschnitt etwa U-förmiges Profil ausgebildeten Klammer, wobei die Schenkelenden des Profils zwei Längskanten der Klammer bilden, die elastisch bis zur gegenseitigen Anlage aufeinander zu beaufschlagt sind, sowie mit zwei im Bereich der Längskante der Klammer angelenkten, mit den Seiten der Klammer in Eingriff bringbaren Hebeln zum Spreizen der Klammer.The invention relates to a device for releasable stapling and stapling of paper sheets or the like, with a clip designed as a cross-section which is approximately U-shaped, the leg ends of the profile forming two longitudinal edges of the clip, which act elastically on one another until they abut against one another are, as well as with two levers articulated in the region of the longitudinal edge of the clip, which can be brought into engagement with the sides of the clip, for spreading the clip.

Derartige Klammern sind als Binder-Klips oder Foldbacks bekannt und insbesondere in Japan und USA im Begrauch. Bei ihnen besteht die Klammer aus einem gebogenen Blech, dessen Längskanten nach aufgerollt sind und kreisförmige Buchsen bilden, in die durch Schlitze von der Mitte her die Enden der aus Draht gebogenen Hebel einsetzbar sind (siehe zum Beispiel US-A 1 865 453). Um die Hebel zu entfernen, müssen deren Enden in Längsrichtung der Längskanten kräftig gedrückt werden. Dies ist außerordentlich umständlich, da darüber hinaus die Hebel nur in Anlage an den Seiten des Profils oder in Anlage an der Oberseite des Papierstapels eine stabile Stellung aufweisen. Aus diesem Grunde werden die Hebel in den meisten Fällen nicht entfernt.Such clips are known as binder clips or foldbacks and are used in particular in Japan and the USA. In the case of them, the clamp consists of a bent sheet metal, the longitudinal edges of which are rolled up and form circular bushings into which the ends of the levers bent from wire can be inserted through slots (see, for example, US Pat. No. 1,865,453). To remove the levers, their ends must be pressed firmly in the longitudinal direction of the longitudinal edges. This is extremely cumbersome, since, moreover, the levers have a stable position only when they rest against the sides of the profile or when they rest against the top of the paper stack. For this reason, the levers are not removed in most cases.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zum lösbaren Verklammern von Papierbögen o.dgl. zu schaffen, die sich einfach und leicht herstellen und ebenso einfach und leicht bedienen läßt.The invention has for its object a device for the releasable stapling of sheets of paper or the like. to create that is simple and easy to manufacture and just as simple and easy to use.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß die Klammer und die Hebel aus Kunstoff gespritzt und die Hebel an den stirnseitigen Enden der Klammer angelenkt sind. Durch die Anlenkung der Hebel an den stirnseitigen Enden der Klammer ist gewährleistet, daß sich die Hebel leichter zum Anbringen und Abnehmen bedienen lassen. Darüber hinaus werden die beim Spreizen der Klammer auftretenden Kräfte aus geometrischen Gründen besser verteilt, so daß die Klammer trotz der Herstellung aus Kunststoff eine hohe Lebensdauer erhält. Die Klammer stört im Computerbereich, im Gegensatz zu den Metallklammern, nicht; sie hat keine scharfen Kanten und ist antimagnetisch.To achieve this object, it is provided according to the invention that the clip and the levers are injection molded from plastic and the levers are articulated on the front ends of the clip. The articulation of the levers at the front ends of the clamp ensures that the levers can be operated more easily for attachment and removal. In addition, the forces occurring when the clamp is spread are better distributed for geometric reasons, so that the clamp has a long service life despite being made of plastic. In contrast to the metal clips, the clip does not interfere in the computer area; it has no sharp edges and is anti-magnetic.

In Weiterbildung kann vorgesehen sein, daß an den stirnseitigen Enden der Längskanten der Klammer Zapfen einstückig angeformt sind, aus die die mit seitlichen Schlitzen versehenen Hebel aufschnappbar sind. Zum Anbringen der Hebel ist also nicht mehr eine in Längsrichtung der Längskanten wirkende Kraft erforderlich, sondern die Hebel können seitlich, d.h. senkrecht zur Papierebene, druckknopfartig aufgeschnappt werden. Dies erleichtert sowohl das Anbringen als auch das Abnehmen der Hebel und damit die Handhabung der von der Erfindung vorgeschlagenen Klammereinrichtung.In a further development, it can be provided that pins are integrally formed on the front ends of the longitudinal edges of the clamp, from which the levers provided with lateral slots can be snapped on. A force acting in the longitudinal direction of the longitudinal edges is no longer required to attach the levers, but the levers can be moved laterally, i.e. perpendicular to the plane of the paper. This facilitates both the attachment and the removal of the levers and thus the handling of the clip device proposed by the invention.

Erfindungsgemäß kann vorgesehen sein, daß die Hebel bügelförmig mit zwei etwa parallel zu den Stirnkanten der Klammer verlaufenden Schenkeln und einem Quersteg ausgebildet und die Schenkel durch eine Platte miteinander verbunden sind. Auf diese Weise greifen die Hebel mit der die Schenkel verbindenden Platte an den Seitenwänden der Klammer an, wodurch sich eine größere Anlagefläche und damit geringere Flächendrücke ergeben. Die Platte braucht dabei nicht an der gesamten Seitenfläche der Klammer anzugreifen, sondern nur im Bereich der den Längskanten abgewandten Enden der Seiten, da an dieser Stelle die auftretenden Kräfte am niedrigsten sind.According to the invention it can be provided that the levers are bow-shaped with two legs running approximately parallel to the end edges of the clamp and a transverse web, and the legs are connected to one another by a plate. In this way, the levers engage with the plate connecting the legs to the side walls of the clamp, which results in a larger contact surface and thus lower surface pressures. The plate does not have to act on the entire side surface of the clamp, but only in the region of the ends of the sides facing away from the longitudinal edges, since the forces occurring at this point are the lowest.

Diese Ausbildung hat den zusätzlichen Vorteil, daß die Schenkelenden eine etwas größere Elastizität aufweisen, so daß sich das Aufschnappen leichter durchführen läßt.This design has the additional advantage that the leg ends have a somewhat greater elasticity, so that the snap-on can be carried out more easily.

Erfindungsgemäß kann vorgesehen sein, daß der Innenabstand der Schenkel des Hebels gleich der Profillänge der Klammer ist. In diesem Fall können die Innenkanten der Schenkel beim Spreizen an den Stirnkanten der Klammer anliegen, so daß eine gegenseitige Führung gegeben ist.According to the invention it can be provided that the inner distance of the legs of the lever is equal to the profile length of the clip. In this case, the inner edges of the legs can rest against the front edges of the clamp when spreading, so that there is mutual guidance.

Erfindungsgemäß kann vorgesehen sein, daß die die Schenkel des Hebels verbindende Platte eine geringere Dicke als die Schenkel aufweist, wobei die Platte vorteilhafterweise derart angeordnet ist, daß sie mit der in Spreizstellung äußeren Seite der Schenkel bündig verläuft. Dadurch werden die Seiten der Klammer beim Spreizen allseitig geführt.According to the invention it can be provided that the plate connecting the legs of the lever has a smaller thickness than the legs, the plate advantageously being arranged such that it is flush with the outer side of the legs in the spreading position. As a result, the sides of the clamp are guided on all sides when spreading.

Zur besseren Haftung an den zu verbindenden Papierbögen kann vorgesehen sein, daß an den aufeinander zu gerichteten Seiten der Längskante der Klammer Vorsprünge angeformt sind. Diese sind vorzugsweise der Klammer an beiden Seiten durch die Längskanten gebildeten Schlitzes angeformt, wobei sie entwe der miteinander abwechseln oder abwechselnd weit vorspringen. Dadurch wird eine Art Zick-Zack-Linie gebildet, die zu einem besonders günstigen Halten der Klammer führt.For better adhesion to the sheets of paper to be connected, it can be provided that projections are formed on the sides of the longitudinal edge of the clip which are directed towards one another. These are preferably formed on both sides of the clip formed by the longitudinal edges of the slot, whereby they either alternate with each other or alternately project far. This creates a kind of zigzag line, which leads to a particularly favorable holding of the clip.

Zum besseren Aufschieben der gespreizten Klammer auf die Papierstapel kann vorgesehen sein, daß die Längskanten der Klammer einen verdickten Querschnitt aufweisen, der insbesondere kreiszylindrisch ausgebildet ist. Dies erleichtert auch die Anbringung der Drehzapfen an den Stirnkanten.In order to better push the spread clip onto the paper stack, it can be provided that the longitudinal edges of the clip have a thickened cross section, which is in particular circular cylindrical. This also makes it easier to attach the trunnions to the front edges.

Fig. 1 zeigt eine Aufsicht auf die Stirnseite einer Klammer 11, die zum lösbaren Verklammern einer Lage von Papierblättern bestimmt ist. Die Klammer 11 ist als Profil ausgebil det, das etwa U-förmig ist. Das Profil enthält zwei Schenkel 12, die durch einen leicht gebogenen Quersteg 13 miteinander verbunden sind. Die freien Enden der Schenkel 12 bilden je eine Längskante 14 der Klammer 11. Die Längerstreckung der Klammer 11 steht senkrecht zur Papierebene der Fig. 1. Beide Längskanten 14 sind verdickt ausgebildet und weisen einen etwa kreisförmigen Querschnitt auf. Die aufeinander zu gerichteten Seiten 15 beider Längskanten 14 der Klammer 11 sind mit Vorsprüngen 16 versehen, wobei in Fig. 1 nur der erste Vorsprung 16 zu sehen ist.Fig. 1 shows a plan view of the end face of a clip 11, which is used for releasably clamping a La is determined by sheets of paper. The bracket 11 is ausgebil det as a profile that is approximately U-shaped. The profile contains two legs 12 which are connected to one another by a slightly curved crosspiece 13. The free ends of the legs 12 each form a longitudinal edge 14 of the clip 11. The longitudinal extension of the clip 11 is perpendicular to the paper plane of FIG. 1. Both longitudinal edges 14 are thickened and have an approximately circular cross section. The sides 15 of both longitudinal edges 14 of the bracket 11 which are directed towards one another are provided with projections 16, only the first projection 16 being visible in FIG. 1.

Auf der dargestellten Stirnseite der Klammer 11 ist in koaxialer Verlängerung der verdickten Längskanten 14 je ein Zapfen 17 einstückig angeformt. Die Zapfen dienen dazu, Hebel anzulenken, mit deren Hilfe die Klammer 11 aus der in fig. 1 dargestellten Stellung derart aufgespreizt werden kann, daß die Längskanten 14 der Klammer 11 zwischen sich einen Schlitz entstehen kann, durch den die Papierkante in das Innere der Klammer 11 eingsechoben werden kann. Durch die elastische Ausbilding der Klammer 11 werden die Längskanten 14 in die dargestellte Stellung beaufschlagt, in der sie mit ihren aufeinander zu gerichteten Seiten 15 aneinander anliegen.On the end face of the bracket 11 shown, a pin 17 is integrally formed in a coaxial extension of the thickened longitudinal edges 14. The pins serve to link levers, with the help of which the bracket 11 from the in Fig. 1 position shown can be spread such that the longitudinal edges 14 of the bracket 11 can create a slot between them, through which the paper edge can be inserted into the interior of the bracket 11. Due to the elastic formation of the clip 11, the longitudinal edges 14 are urged into the position shown, in which they rest against one another with their sides 15 directed towards one another.

Fig. 2 zeigt die Klammer 11 von der Seite her, d.h. von rechts bzw. links in Fig. 1, wobei oberhalb der Klammer 11 einer der Hebel dargestellt ist. Die Seitenflächen 18 der Klammer 11 erstrecken sich in Längsrichtung von der einen Stirnseite 19 bis zu der anderen Stirnseite 20. Die beiden Stirnseiten 19, 20 verlaufen in der Seitenansicht der Fig. 2 parallel zueinander. Die stirnseitigen Enden 21 der Längskanten 14 verlaufen bündig zu den Stirnseiten 19, 20 der Klammer 11. Die Zapfen 17 erstrecken sich über die stirnseitigen Enden 21 der Längskanten 14 in beide Richtungen.Figure 2 shows the bracket 11 from the side, i.e. from the right or left in Fig. 1, one of the levers being shown above the bracket 11. The side faces 18 of the clamp 11 extend in the longitudinal direction from one end face 19 to the other end face 20. The two end faces 19, 20 run parallel to one another in the side view of FIG. 2. The front ends 21 of the longitudinal edges 14 run flush with the end faces 19, 20 of the bracket 11. The pins 17 extend over the front ends 21 of the longitudinal edges 14 in both directions.

Beide identisch ausgebildeten, mit der Klammer 11 zusammenwirkenden Hebel 22 weisen etwa die Form eines U-förmigen Bügels mit zwei Schenkeln 23 auf, die durch einen Quersteg 24 miteinander verbunden sind, wobei die Verbindungsstellen 25 abgerundet verlaufen. Die von dem Quersteg 24 abgewandten Enden 26 der Schenkel 23 weisen je einen Schlitz 27 auf, der zur Seitenfläche, in Fig. 2 dargestellt, offen ist. Mit Hilfe dieser Schlitze 27, deren Innendurchmesser etwa dem Außendurchmesser der Zapfen 17 entsprechen, etwas kleiner ist als dieser, lassen sich die Hebel 22 mit ihren Schenkeln 23 auf die Zapfen 17 von der Seite her aufschnappen, d.h. in Fig. 2 von oben her.Both identically designed levers 22 which cooperate with the clamp 11 have approximately the shape of a U-shaped bracket with two legs 23 which are connected to one another by a cross piece 24, the connecting points 25 being rounded. The ends 26 of the legs 23 facing away from the crosspiece 24 each have a slot 27 which is open to the side surface, shown in FIG. 2. With the help of these slots 27, whose inner diameter corresponds approximately to the outer diameter of the pin 17, is slightly smaller than this, the levers 22 can be snapped onto the pin 17 with their legs 23 from the side, i.e. 2 from above.

Die Schenkel 23 und der Quersteg 24 des Hebels 22 sind durch eine Platte 28 miteinander verbunden, die einstückig mit den Schenkeln 23 und dem Quersteg 24 ausgebildet ist. Die Längskante 29 der Platte 28 weist einen Abstand von der Mittelachse der Schlitze 27 auf, der kleiner ist als der Abstand zwischen der Mittelachse der Zapfen 17 und der Außenseite 30 des Querstegs 13 der Klammer 11. Dadurch liegt die Platte 28 an den Seitenflächen 18 der Klammer 11 an, wenn die Hebel mit den Schlitzen 27 auf die Zapfen 17 aufggeschnappt sind und die Hebel zum Spreizen der Klammer 11 verwendet werden. Die auftretenden Drücke verteilen sich auf die gesamte Länge der Seitenflächen 18 der Klammer 11.The legs 23 and the crossbar 24 of the lever 22 are connected to one another by a plate 28 which is formed in one piece with the legs 23 and the crossbar 24. The longitudinal edge 29 of the plate 28 is at a distance from the central axis of the slots 27 which is smaller than the distance between the central axis of the pins 17 and the outside 30 of the transverse web 13 of the bracket 11. As a result, the plate 28 lies on the side faces 18 of the Clip 11 when the levers with the slots 27 are snapped onto the pins 17 and the levers are used to spread the clip 11. The pressures occurring are distributed over the entire length of the side surfaces 18 of the bracket 11.

Die Innenseite 31 jedes Schenkels 23 des Hebels 22 verläuft parallel zu der jeweils zugehörigen Stirnseite 19 bzw. 20 der Klammer 11. Gleichzeitig ist der gegenseitige Abstand der Innenseiten 31 der Schenkel 23 gleich groß dem Längsabstand der beiden Stirnseiten 19, 20 der Klammer 11.The inside 31 of each leg 23 of the lever 22 runs parallel to the associated end face 19 or 20 of the bracket 11. At the same time, the mutual distance between the inside 31 of the leg 23 is equal to the longitudinal distance between the two end faces 19, 20 of the bracket 11.

Fig. 3 zeigt den Hebel 22 von der anderen Seite. Da die Platte 28 eine kleinere Dicke aufweist als die Schenkel 23 und der Quersteg 24 und die Platte 28 bündig mit der in Fig. 2 oberen Fläche von Schenkeln 23 und Quersteg 24 ver läuft, ist auf der in Fig. 3 oberen Seite ein umlaufender Rand 32 gebildet. Werden die Hebel 22 in Spreizstellung der Klammer gebracht, so liegen diese Seitenflächen 18 der Klammer 11 innerhalb des Randes 32, so daß die Stirnseiten 19, 20 von der Innenseite 31 der Schenkel 23 und die Fläche 18 von der Innenseite der Platte 28 geführt werden. Dadurch wird eine gute Kraftübertragung auf eine möglichst große Fläche erreicht.Fig. 3 shows the lever 22 from the other side. Since the plate 28 has a smaller thickness than the legs 23 and the transverse web 24 and the plate 28 runs flush with the upper surface of the legs 23 and transverse web 24 in FIG. 2, there is a peripheral edge on the upper side in FIG. 3 32 formed. If the levers 22 are brought into the spread position of the clamp, these side surfaces 18 of the clamp 11 lie within the edge 32, so that the end faces 19, 20 are guided from the inside 31 of the legs 23 and the surface 18 from the inside of the plate 28. This ensures good power transmission to as large an area as possible.

Fig. 4 zeigt eine Ansicht der Klammer 11 von unten in Fig. 1. Die vier Zapfen 17 liegen koaxial zu den zylindrisch verbreiterten Längskanten 14 der Klammer. An beiden aufeinander zu gerichteten Seiten der Längskanten sind Vorsprünge 16 angeordnet, wobei in der dargestellten Ausführungsform an der oberen Längskante 14 drei Vorsprünge 16 und an der unteren zwei Vorsprünge 16 angeordnet sind. Die einzelnen Vorsprünge sind abwechselnd an den beiden Längskanten 14 angeordnet und bilden zwischen sich eine etwa wellenförmig verlaufende Öffnung. In Längsrichtung der Klammer 11 besitzen die Vorsprünge 16 einen gegenseitigen Abstand.FIG. 4 shows a view of the clip 11 from below in FIG. 1. The four pins 17 lie coaxially with the cylindrically widened longitudinal edges 14 of the clip. Projections 16 are arranged on both sides of the longitudinal edges facing each other, in the embodiment shown three projections 16 being arranged on the upper longitudinal edge 14 and two projections 16 on the lower. The individual projections are arranged alternately on the two longitudinal edges 14 and form an approximately wavy opening between them. In the longitudinal direction of the bracket 11, the projections 16 are spaced apart.

Fig. 5 zeigt einen Schnitt durch die mit den Hebeln versehene Klammer. Die Hebel derart verschwenkt, daß die Innenseite der Platte 28 an der Außenseite der Seitenfläche 18 der Klammer 11 angreift. Die Seitenflächen 18 der Klammer 11 werden in Fig. 5 unten und oben, d.h. an ihren Stirnseiten 19, 20, von dem Rand 32 an der Innenseite der Schenkel 23 geführt. Die Schlitze 27 öffnen sich zu den jetzt nach außen gerichteten Seitenflächen der Hebel 22 und nehmen die Zapfen 17 in sich auf. Werden nun die freien, durch den Quersteg 24 gebildeten Enden der Hebel 22 aufeiander zu gedrückt, so spreizen sie die Klammer 11 derart, daß deren Längskanten 14 voneinander wegbewegt werden und zwischen sich einen Längsschlitz freigeben. Dann kann die gespreizte Klammer auf einen Stapel Papier o.dgl. aufgeschoben werden. Nach Loslassen der Hebel 22 verklammert sich die Klammer 11 an dem Pa pierstapel aufgrund ihrer Elastizität. Die Hebel 22 können dann in entgegengesetzer Drehrichtung verschwenkt werden, bis sie auf der Papieroberfläche aufliegen. Dann können sie einfach entnommen werden, indem eine leichte Kraft senkrecht zur Papierebene und damit senkrecht zur Längskante 14 der Klammer 11 ausgeübt wird. Selbstverständlich ist es auch möglich, nur einen Hebel 22 abzunehmen und den Papierstapel mit dem anderen Hebel, dessen Platte 28 ein Loch 33 aufweist, an einem Nagel oder einem Haken aufzuhängen.Fig. 5 shows a section through the bracket provided with the levers. The levers pivoted such that the inside of the plate 28 engages the outside of the side surface 18 of the bracket 11. The side surfaces 18 of the bracket 11 are shown in Fig. 5 below and above, i.e. on their end faces 19, 20, from the edge 32 on the inside of the legs 23. The slots 27 open towards the now outward-facing side surfaces of the levers 22 and accommodate the pins 17. If the free ends of the levers 22 formed by the crosspiece 24 are pressed towards one another, they spread the clamp 11 in such a way that their longitudinal edges 14 are moved away from one another and release a longitudinal slot between them. Then the spread bracket or the like on a stack of paper. be postponed. After releasing the lever 22, the clip 11 clings to the paper stack due to its elasticity. The levers 22 can then be pivoted in the opposite direction of rotation until they rest on the paper surface. Then they can be removed simply by exerting a slight force perpendicular to the plane of the paper and thus perpendicular to the longitudinal edge 14 of the clamp 11. Of course, it is also possible to remove only one lever 22 and to hang the paper stack with the other lever, the plate 28 of which has a hole 33, on a nail or a hook.

Soll der Papierstapel als ein zusammenhängender Block beispielsweise mit der Post verschickt werden, können beide Hebel abgenommen werden.Shall the paper stack be a coherent Block can be sent by post, for example, both levers can be removed.

Das Wiederanbringen des Hebels, um den Papierstapel zu lösen, ist besonders einfach. Der Hebel wird derart in die Nähe der Klammer gebracht, daß sein Schlitz 27 dem Zapfen 17 gegenüberliegt. In dieser Stellung kann der Hebel 22 durch die Abmessungen der Innenseiten der Schenkel 23 an der Klammer geführt werden, so daß keinerlei Schwiergkeiten vorhanden sind, die Hebel wieder an der Klammer anzubringen.Reattaching the lever to release the paper stack is particularly easy. The lever is brought close to the clamp so that its slot 27 is opposite the pin 17. In this position, the lever 22 can be guided through the dimensions of the inner sides of the legs 23 on the bracket, so that there are no difficulties in reattaching the levers to the bracket.

Fig. 6 zeigt die Klammer in geöffnetem Zustand, in den sie durch Krafteinwirkung in Richtung der Pfeile gebracht werden kann.Fig. 6 shows the clip in the open state, in which it can be brought by force in the direction of the arrows.
