Description

Vorrichtung zum mechanischen Verbinden von DokumentenDevice for mechanically connecting documents
Die Erfindung betrifft eine Vorrichtung zum mechanischen Verbinden von Dokumenten nach dem Oberbegriff des unabhängigen Patentanspruches.The invention relates to a device for mechanical connection of documents according to the preamble of the independent claim.
Ueblicherweise werden heute Dokumente im Umfange von einigen Seiten, respektive Papierblättern geheftet. Dazu werden einfache Klammerhefter verschiedener Grosse verwendet. Diese bestehen aus einem Sockel, einem damit schwenkbar verbundenen Klammermagazin und einem mit beiden schwenkbar um die gleiche Achse verbundenen Deckel mit Stempel. Die Papiere werden gebündelt zwischen Klammermagazin und Sockel gehalten, darauf wird der Deckel heruntergedrückt, wobei der Stempel eine Klammer aus dem Klammermagazin nach unten durch die Papiere auf den Sockel drückt. Die Klammer wird an einer Kulisse auf dem Sockel umgebogen. Oft ist die Verwendung von Metallklammern aber nicht erwünscht oder sogar verboten. Sie sind beispielsweise bei der Altpapierverwertung hinderlich. Daher sind verschiedene Ansätze entstanden, eine klammerlose Heftung herzustellen. 2Today, documents are usually stapled with a few pages or sheets of paper. Simple staplers of various sizes are used for this. These consist of a base, a clamp magazine pivotally connected to it and a cover with stamp which is pivotally connected to both about the same axis. The papers are held bundled between the clip magazine and the base, the cover is pressed down, the stamp pushing a clip from the clip magazine down through the papers onto the base. The clip is bent against a backdrop on the base. However, the use of metal clips is often undesirable or even prohibited. For example, they are a hindrance in the recycling of waste paper. Therefore, different approaches have emerged to produce a stapling without staples. 2nd
Ein solcher klammerlos arbeitender Hefter ist aus US 3 577 575 (Fumio Taniguchi) bekannt. Der Aufbau entspricht den Klammerheftern. Statt Klammern durchs Papier zu stossen, wird mit einem Stanzmesser eine Papierzunge dreiseitig ausgestanzt. Gleichzeitig wird in kurzem Abstand davon mit einem Stichel ein Schnitt quer dazu ins Papier geschnitten. Der Stichel weist eine Oese auf. Im Stanzmesser befindet sich ein Schwenknocken. Dieser wird nach dem Stanzen der Zunge geschwenkt. Er biegt dabei die ausgeschnittene Papierzunge rückwärts und führt sie in die Ausnehmung am Stichel. Beim Loslassen des Heftapparates zieht sich die Schwenkklinge und der Stichel aus dem Papier zurück. Dabei wird die Papierzunge vom Stichel durch den Schlitz auf die andere Seite des Papiers durchgezogen. Somit werden die Papierlagen durch die ausgeschnittenen und durchgezogenen Papierzungen zusammengehalten. Dieses Gerät weist den Vorteil auf, dass keine metallischen oder andere Klammern benötigt werden. Die Klammerung erfolgt nur durch das Papier selbst. Allerdings sind die Klingen beim geöffneten Hefter freistehend. Sie werden leicht beschädigt und stellen für den Benutzer eine erhebliche Verletzungsgefahr dar. Diese Heftapparate sind aus über 30 Einzelteilen zusammengesetzt.Such a stapler without a staple is known from US 3,577,575 (Fumio Taniguchi). The structure corresponds to the staplers. Instead of poking staples through the paper, a paper tongue is punched out on three sides with a punch knife. At the same time, a cut is cut across the paper with a prick. The stylus has an eyelet. There is a swivel cam in the punch knife. This is pivoted after punching the tongue. He bends the cut-out paper tongue backwards and guides it into the recess on the stylus. When the stapler is released, the swivel blade and the stylus withdraw from the paper. The paper tongue is pulled through the slot through the slot to the other side of the paper. Thus, the paper layers are held together by the cut and solid paper tongues. This device has the advantage that no metallic or other clips are required. The stapling is only done by the paper itself. However, the blades are free-standing when the stapler is open. They are easily damaged and pose a considerable risk of injury to the user. These staplers are composed of over 30 individual parts.
Aufgabe der Erfindung ist es, eine Heftvorrichtung zu schaffen, bei welcher die Stanz- und Schneidelemente bei sowohl im Ruhezustand, wie auch beim Gebrauch nicht frei, sondern vollständig geschützt sind. Sie sollen nicht beschädigt werden können und sie sollen keinerlei Verletzungsgefahren für den Benutzer darstellen.The object of the invention is to provide a stapling device in which the punching and cutting elements are not free but completely protected both in the idle state and in use. They should not be able to be damaged and they should not pose any risk of injury to the user.
Diese Aufgabe wird durch die in den Patentansprüchen angegebene Erfindung gelöst.This object is achieved by the invention specified in the patent claims.
Ein weiterer Vorteil der Erfindung besteht darin, dass eine Heftvorrichtung gemäss Erfindung aus nur 7 Einzelteilen gebaut werden kann. Diese senkt die Herstellungskosten erheblich und vermindert die Störungsanfälligkeit.Another advantage of the invention is that a stapling device according to the invention is built from only 7 individual parts can be. This lowers the manufacturing costs considerably and reduces the susceptibility to faults.

In Figur 1 ist eine Vorrichtung gemäss Erfindung im Querschnitt mit eingelegten Papierbahnen im Ruhezustand dargestellt. Sie besteht aus drei Hauptelementen nämlich Sockel 1, Schiebeelement 3 und Deckel 2.In Figure 1, a device according to the invention is shown in cross section with inserted paper webs in the idle state. It consists of three main elements, namely base 1, sliding element 3 and cover 2.
Der Sockel 1 ist im Querschnitt U-förmig, er weist an den seitlichen Flanken einwärts ragende erste Rückhaltenocken 11 auf. Am Boden des Sockels 1 ist ein Lagerbock 12 angeordnet. Daran ist ein Stanz-Biege-Element 15 schwenkbar befestigt, ebenfalls ist daran ein nach oben ragender Stichel 14, welcher Schneiden und eine Oese aufweist, befestigt. Das Stanz-Biege- Element 15 ist am Lagerbock 12 an einer Schwenkbefestigung 151 schwenkbar gehalten. Es weist einen Mitnehmer 154, zum Wirkverbund mit einem Nocken 35, und eine als Stanzstempel 152 ausgestaltete Fläche auf. Das Stanz-Biege-Element 15 wird durch eine Rückstellfeder 13 in seine Ruheposition gedrückt.The base 1 is U-shaped in cross section, it has first retaining cams 11 projecting inwards on the side flanks. A bearing block 12 is arranged on the base of the base 1. A punch-bending element 15 is pivotally attached to it, and an upwardly projecting stylus 14, which has cutting edges and an eyelet, is also attached to it. The punching-bending element 15 is pivotally held on the bearing block 12 on a swivel fastening 151. It has a driver 154, for the active connection with a cam 35, and a surface designed as a punch 152. The stamping and bending element 15 is pressed into its rest position by a return spring 13.
Das Schiebeelement 3 weist ebenfalls im Querschnitt eine unten offene U-Form auf. Das Schiebeelement 3 ist so bemessen, dass es genau geführt im Sockel 1 einschiebbar gehalten ist. Es weist seitlich nach aussen ragende zweite Rückhaltenocken 33 auf, welche im Ruhezustand an den ersten Rückhaltenocken 11 anschlagen und die Lage des Schiebeelementes 3 so begrenzen. Eine Feder 32 drückt das Schiebeelement 3 in diese Ruhestellung. Weitere Führungen zur exakten Verschiebbarkeit des Schiebeelementes 3 könne vorgesehen sein. Das Schiebeelement 3 ist oben aussen als Papierauflage 31 eben ausgestaltet, es weist im inneren eine erste Ausnehmung 311 auf, welche in seine Fläche der auf drei Seiten auszustanzenden Papierzunge und als Matrize dem Stanzstempel 152 des Stanz- Biege-Elementes 15 entspricht. Beabstandet davon befindet sich eine zweite Ausnehmung 312, welche als Matrize für den Stichel 14 vorgesehen ist. Zwischen diesen Ausnehmungen 311 und 312 ist das ebene Stück der Papierauflage 31 nach unten als Nocken 35 erweitert. Der Nocken 35 dient zum Wirkverbund zum Schwenken des Stanz-Biege-Elementes 15.The sliding element 3 also has a U-shape which is open at the bottom in cross section. The sliding element 3 is dimensioned such that it is held in the base 1 in a precisely guided manner. It has laterally outwardly projecting second retaining cams 33 which in the idle state strike the first retaining cams 11 and thus limit the position of the sliding element 3. A spring 32 pushes the sliding element 3 into this rest position. Further guides for the exact displaceability of the sliding element 3 could be provided. The sliding element 3 is flat on the outside outside as a paper support 31, it has a first recess 311 on the inside, which corresponds in its area to the paper tongue to be punched out on three sides and as a die to the punch 152 of the punching and bending element 15. Spaced from this is a second recess 312, which is provided as a matrix for the stylus 14. Between these recesses 311 and 312, the flat piece of paper support 31 is expanded downwards as cams 35. The cam 35 serves as an active compound for pivoting the punching and bending element 15.
Der Deckel 2 ist im Querschnitt ebenfalls ein unten offenes U- Profil. Im Innern befindet sich eine Matrize 25 mit einem Sackloch 26. Diese Matrize 25 respektive das Sackloch 26 entspricht in seiner Grundfläche den Bereichen der ersten und der zweiten Ausnehmung 311, 312 im Schiebeelement 3 und damit dem von der Spitze des Stichels und vom Stanz-Biege-Element benötigten Raum beim Herunterdrücken des Deckels 2 und somit des Schiebeeelementes 3 in den Sockel 1. Der Deckel 2 ist randständig schwenkbar mit dem Schiebeelement 3 scharnierartig schwenkbar verbunden.The cover 2 is also a U-profile open at the bottom in cross section. Inside is a die 25 with a blind hole 26. This die 25 or the blind hole 26 corresponds in its base area to the areas of the first and second recesses 311, 312 in the sliding element 3 and thus the space required by the tip of the stylus and the stamping and bending element when pressing down the cover 2 and thus the sliding element 3 into the base 1. The cover 2 is pivotally connected to the sliding element 3 in a hinge-like manner.
Der Vorgang des Heftens ist im Ablauf aus den Figuren 1 bis drei ersichtlich. Zuerst wird der Deckel 2 zurückgeschwenkt, worauf einige Papierbahnen 4 auf die Papierauflage 31 aufgelegt werden. Stichel 14 und Stanz-Biege-Element 15 befinden gemäss Figur 1 sich vollständig zwischen dem Schiebeelement 3 und dem Boden des Sockels im inneren verdeckt und geschützt. Darauf wird der Deckel 2 wieder zurückgeschwenkt. Die Papierbahnen 4 sind überdeckt.The process of stapling can be seen in the sequence from FIGS. 1 to three. First, the lid 2 is pivoted back, whereupon some paper webs 4 are placed on the paper support 31. According to FIG. 1, the stylus 14 and the punching-bending element 15 are completely hidden and protected between the sliding element 3 and the base of the base. Then the cover 2 is pivoted back again. The paper webs 4 are covered.
Nun drückt man auf den Deckel 2 und presst gegen die Wirkung der Kraft der Feder 32 das Schiebeelement 3 nach unten in den Sockel 1. Dabei stossen nun Stichel 14 und Stanz-Biege-Element 15 durch die Papierbahnen nach oben. Der Stichel 14 erzeugt dabei einen Schnitt durch die Papierbahnen und das Stanz-Biege- Element 15 schneidet eine Zunge 41 dreiseitig in die Papierbahnen. Die Zunge 41 bleibt an der gegen den Schnitt des Stichels 14 gerichteten Seite an den Papierbahnen fest. Sobald das Schiebeelement 3 um ein bestimmtes Mass in den soweit in den Sockel 1 eingeschoben ist, so kommt der Nocken 35 mit dem Mitnehmer 154 des Stanz-Biege-Elementes 15 in Kontakt und drückt diesen hinunter. Dadurch wird das Stanz-Biege-Element 15 um das Schwenklager 151 geschwenkt in Richtung zum Stichel. Mit seiner Nase 153 biegt er die Papierzungen 41 rückwärts und stösst deren freie Enden durch die nun frei werdende Oese 142 im Stichel gemäss Figur 2.Now press on the cover 2 and press the sliding element 3 down into the base 1 against the action of the force of the spring 32. The graver 14 and the punching and bending element 15 now push upwards through the paper webs. The stylus 14 creates a cut through the paper webs and the stamping and bending element 15 cuts a tongue 41 on three sides into the paper webs. The tongue 41 remains fixed to the paper webs on the side directed against the cut of the stylus 14. As soon as the sliding element 3 has been inserted into the base 1 by a certain amount, the cam 35 comes into contact with the driver 154 of the stamping and bending element 15 and presses it down. As a result, the stamping and bending element 15 is pivoted about the pivot bearing 151 in the direction of the stylus. With his nose 153 he bends the paper tongues 41 backwards and pushes their free ends through the now released eyelet 142 in the stylus according to FIG. 2.
Nun wird der Deckel 2 wieder losgelassen, die Feder 32 presst das Schiebeelement 3 zurück in seine Ruhestellung. Dabei werden die Papierzungen 41 von der Oese 142 im Stichel durch denNow the lid 2 is released again, the spring 32 presses the sliding element 3 back into its rest position. In doing so the paper tongues 41 from the eyelet 142 in the prick through the
Schnitt in den Papierbahnen 4 hindurchgezogen auf die Unterseite der Papierbahnen, wie in Figur 3 ersichtlich. Im Bereich der ausgeschnittenen Zungen 41 existiert nun eine Kleine Oeffnung im Papier. Die Zungen 41 bilden eine Schlaufe auf der Oberseite der Papierbahnen, sind durch den Schlitz auf die Unterseite geführt und liegen etwa an der Unterseite der Papierbahnen an. Der Deckel 2 kann zurückgeschwenkt werden und die gehefteten Papierbahnen 4 aus der Vorrichtung entfernt werden. Der Hefter kann von neuem benützt werden.Section in the paper webs 4 drawn through to the underside of the paper webs, as can be seen in FIG. 3. In the area of the cut-out tongues 41 there is now a small opening in the paper. The tongues 41 form a loop on the top of the paper webs, are guided through the slot on the underside and lie approximately on the underside of the paper webs. The lid 2 can be pivoted back and the stapled paper webs 4 can be removed from the device. The stapler can be used again.
Der Stichel 14 ist in Figur 4 in Vorderansicht dargestellt. Sie ist ähnlich einer Nähnadel. Gut ersichtlich sind die SchneidenThe stylus 14 is shown in FIG. 4 in a front view. It is similar to a sewing needle. The cutting edges are clearly visible
141 zum erzeugen des Schlitzes in den Papierbahnen und die Oese141 to create the slit in the paper webs and the eyelet
142 etwas darunter.142 a little below.
Der Verlauf von Papierbahnen im gehefteten Zustand ist in Figur 5 dargestellt. Die Zungen 41 der Papierbahnen sind umgebogen oder sogar umgefaltet 42, etwa senkrecht 43 durch den Schnitt gezogen und liegen mit ihrem freien Ende 44 annähernd an der Unterseite der Papierbahnen an.The course of paper webs in the stapled state is shown in FIG. 5. The tongues 41 of the paper webs are bent or even folded over 42, drawn approximately perpendicularly 43 through the cut, and their free end 44 lies approximately on the underside of the paper webs.
Eine Uebersicht über die Vorrichtung ist in Figur 6 gezeigt. Der Schiebeteil 3 ist in seiner Grundfläche minim kleiner als der Sockel 1. Der Deckel 2 entspricht in seiner Grundfläche etwa dem Schiebeteil 3. Er ist mit den Schwenkgelenken 21 mit dem Schiebeteil im Bereich einer Kante schwenkbar verbunden. Der Schiebeteil 3 ist teleskopisch in den Sockel 1 einschiebbar durch Drücken auf den Deckel 2. Dieses Einschieben betätigt dabei den Heftvorgang wie oben beschrieben.An overview of the device is shown in FIG. 6. The base part of the sliding part 3 is minimally smaller than the base 1. The base surface of the cover 2 corresponds approximately to the sliding part 3. It is pivotally connected to the sliding part 21 in the region of an edge by the swivel joints 21. The sliding part 3 is telescopically insertable into the base 1 by pressing on the cover 2. This insertion actuates the stapling process as described above.
Das Stanz-Biege-Element 15 ist mehr detailliert in einer Ansicht in der Figur 7 dargestellt. Der Stanzstempel 152 weist eine Schnittfläche 155 auf, welche die Form der auszuschneidenden Papierzungen entspricht, diese SchnittflächeThe stamping and bending element 15 is shown in more detail in a view in FIG. 7. The punch 152 has a cut surface 155 which has the shape of the corresponds to the paper tongues to be cut out, this cut surface
155 ist durch Schnittkanten 156 auf drei Seiten zum Schneiden respektive Stanzen ausgestaltet. Diese Schnittkanten 156 können gehärtet oder nach oben leicht vorstehend gearbeitet sein. Die Ausführung der Schnittfläche 155 kann in einer bevorzugten Ausführungsform auch leicht nach oben gewölbt sein, wie es in der Figur 7 dargestellt ist. Sie zeigt dann das Bild eines Ausschnittes aus einer Zylinderfläche dar. Diese Ausführung schneidet die Papierzungen sehr präzise und leitet dabei gleichzeitig den Umbiegevorgang ein. Die Schnittfläche 155 geht an ihrem nicht schneidenden Ende in die Nase 153 über. Die Nase155 is configured by cutting edges 156 on three sides for cutting or punching. These cut edges 156 can be hardened or slightly protruding upwards. In a preferred embodiment, the cut surface 155 can also be curved slightly upward, as shown in FIG. 7. It then shows the image of a section of a cylindrical surface. This design cuts the paper tongues very precisely and at the same time initiates the bending process. The cut surface 155 merges with the nose 153 at its non-cutting end. The nose
153 beendet das Rückwärtsbiegen der gestanzten Papierzungen und faltet sie, indem sie die Papierzunge gegen die Papierbahnenfläche und die Papierauflage presst. Der Mitnehmer153 stops bending the punched paper tongues back and folds them by pressing the paper tongue against the paper web surface and the paper support. The driver
154 ist als Absatz des ganzen Teiles ausgestaltet. Beim Einschieben des Schiebeteiles 3 drückt der Nocken 35 der Papierauflage 3 auf diesen Mitnehmer 154 und bewirkt das Schwenken des Stanz- Stempels 15 und damit den Schneid- Biege- und Faltprozess. An geeigneter Stelle im Abstand von Mitnehmer 154, Nase 153 und Stanzstempel 152 befindet sich das Schwenklager 151.154 is designed as a paragraph of the whole part. When the sliding part 3 is pushed in, the cam 35 of the paper support 3 presses on this driver 154 and causes the stamping punch 15 to pivot and thus the cutting, bending and folding process. The swivel bearing 151 is located at a suitable point at a distance from the driver 154, nose 153 and punch 152.
Insbesondere aus der Figur 6 ist gut ersichtlich, dass die neue Heftvorrichtung die Stanz- und Schneidelemente bei sowohl im Ruhezustand, wie auch beim Gebrauch vollständig geschützt sind. Sie können nicht beschädigt können. Der Benutzer kann sich daher daran auch nicht verletzen. Zum leichteren Entfernen von gehefteten Papieren aus der Vorrichtung ist der Deckel im Bereich des Schwenkgelenkes mit einer kleinen Schikane 22 versehen, welche den Deckel durch anschlagen seitlich am Schiebeteil 3 minimal anhebt. Dies ermöglicht, gebundene Papiere herauszuziehen, ohne dass der Deckel 2 geöffnet werden muss. It can be seen particularly well from FIG. 6 that the new stapling device protects the punching and cutting elements completely, both in the idle state and in use. They cannot be damaged. The user can therefore not hurt himself. To make it easier to remove stapled papers from the device, the cover is provided with a small chicane 22 in the region of the swivel joint, which minimally raises the cover by striking it laterally on the sliding part 3. This makes it possible to pull out bound papers without having to open the lid 2.
