Description

Die Erfindung betrifft eine Vorrichtung zum Binden von Musterheften, umfassend eine Schraube mit einem Schraubenkopf und einem an diesem angeformten Gewindezapfen und eine die Schraube aufnehmende Schraubhülse mit einem Schraubenkopf und einem an diesem angeformten, ein Innengewinde aufweisenden Hülsenteil.The invention relates to a device for binding pattern books, comprising a screw with a screw head and a threaded pin formed on this and a screw receiving screw with a screw head and an integrally formed on this, having an internal thread sleeve part.

Derartige Buchschrauben sind seit langem bekannt und dienen insbesondere zum Bündeln von flächigem Material und hierbei vorzugsweise von Mustermaterial jeglicher Art, zum Beispiel bei Musterbündeln, Fächerbündeln usw. Die Muster können mit Lochungen unmittelbar auf die Schafte der Buchschrauben aufgereiht sein oder sie können auf Karten aus geeignetem Material aufgeklebt oder aufgeheftet sein, welche Karten anschließend mit Lochungen auf die Schafte aufgereiht werden. Das Mustermaterial besteht beispielsweise aus Mustern von Webstoffen, Wirkstoffen, Filz, Leder oder Kunststoffen. Auch kommen Buchschrauben zum Bündeln von Lichtbildern, Zeichnungen, Dokumenten oder Schriftstücken zum Einsatz.Such book screws have long been known and are used in particular for the bundling of sheet material and this preferably of pattern material of any kind, for example, pattern bundles, fan bundles, etc. The patterns can be strung with holes directly on the shafts of book screws or they can be on cards from suitable Material glued or stapled, which cards are then strung with holes on the shaft. The pattern material consists for example of patterns of woven fabrics, active ingredients, felt, leather or plastics. Also book screws come to Bundling of photographs, drawings, documents or documents for use.

Zur Präsentation von Mustermaterial ist es oftmals erforderlich, die Buchschraube mit zusätzlichen Befestigungsmitteln zu versehen, um das Mustermaterial beispielsweise an Demonstrationsständern aufhängen zu können. Hierbei handelt es sich beispielsweise um mit Haken versehene Hülsen, welche ebenfalls auf den Schaft der Buchschraube aufgeschoben wird. Nachteilig an der vorbekannten Lösung ist, dass durch das zusätzliche Befestigungselement die Kapazität des Schaftes für das Mustermaterial vermindert wird. Darüber hinaus besteht die Gefahr der Beschädigung von Mustern durch das zwischen diesen angeordnete Befestigungselement.For the presentation of sample material, it is often necessary to provide the book screw with additional fasteners to hang the sample material, for example, on demonstration stands can. These are, for example, provided with hooks sleeves, which is also pushed onto the shaft of the book screw. A disadvantage of the previously known solution is that the capacity of the shaft for the pattern material is reduced by the additional fastening element. In addition, there is a risk of damage to patterns by the arranged between these fastener.

Hier will die Erfindung Abhilfe schaffen. Der Erfindung liegt die Aufgabe zu Grunde, eine Vorrichtung zum Bündeln von Musterheften zu schaffen, die eine Befestigung des Musterheftes ohne eine mögliche Beeinträchtigung der Muster im Gebrauch ermöglicht. Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass die Schraube und die Schraubhülse entlang ihrer Rotationsachse jeweils eine Durchgangsbohrung aufweisen, die in eine jeweils in dem Schraubkopf eingebrachte Bohrung mündet, so dass im verschraubten Zustand ein Durchgangskanal zur Aufnahme einer Kugelkette gebildet ist.The invention aims to remedy this situation. The invention has for its object to provide a device for bundling pattern books, which allows attachment of the pattern booklet without a possible impairment of the pattern in use. According to the invention, this object is achieved in that the screw and the screw sleeve along their axis of rotation in each case have a through hole, which opens into a respectively introduced in the screw head bore, so that in the screwed state, a through channel is formed for receiving a ball chain.

Mit der Erfindung ist eine Vorrichtung zum Bündeln von Musterheften geschaffen, die eine Befestigung des Musterheftes ohne eine mögliche Beeinträchtigung der Muster im Gebrauch ermöglicht. Durch den Durchgangskanal kann eine Kugelkette oder eine Kordel geführt werden, die, ohne mit den Mustern in Kontakt zu treten, als Aufhänger genutzt werden kann.The invention provides a device for bundling pattern booklets, which allows attachment of the pattern booklet without possible impairment of the patterns in use. Through the passageway, a ball chain or a cord can be guided, which, without coming into contact with the patterns, can be used as a hanger.

In Weiterbildung der Erfindung weist das Hülsenteil der Schraubhülse eine Länge auf, die größer gleich der Länge des Gewindezapfens der Schraube ist, so dass im verschraubten Zustand der Schraubkopf der Schraube auf dem Hülsenteil der Schraubhülse aufliegt. Hierdurch ist eine gleichmäßige, glatte Aufnahme für die Muster geschaffen, wodurch ein Verhaken der Muster im Gebrauch entgegengewirkt ist.In development of the invention, the sleeve part of the screw on a length which is greater than or equal to the length of the threaded pin of the screw, so that in the screwed state of the screw head of the screw rests on the sleeve part of the screw.

In Ausgestaltung der Erfindung sind die Schraube und / oder die Schraubhülse aus Kunststoff hergestellt. Hierdurch ist eine im Gegensatz zur bisher bekannten Herstellung der Buchschrauben aus Metall wesentlich kostengünstigere Herstellung ermöglicht, welche sich zum Einen durch den geringeren Fertigungsaufwand und zum Anderen durch die geringeren Materialkosten begründet. Da es sich bei der Vorrichtung um ein Massenprodukt handelt, haben bereits geringste Aufwandsreduzierungen erhebliche Wirkungen. Vorteilhaft sind die Schraube und / oder die Schraubhülse als Kunststoffspritzgussteil ausgeführt.In an embodiment of the invention, the screw and / or the screw sleeve are made of plastic. As a result, in contrast to the previously known production of book screws made of metal significantly cheaper production is possible, which is based on the one hand by the lower production costs and on the other hand by the lower material costs. Since the device is a mass product, even the smallest cost reductions have significant effects. The screw and / or the screw sleeve are advantageously designed as a plastic injection molded part.

In Weiterbildung der Erfindung sind die Schraube und / oder die Schraubhülse aus recyclingfähigem Kunststoff, vorzugsweise Polyamid, herstellt. Hierdurch ist den Anforderungen an die Umweltverträglichkeit Rechnung getragen.In a further development of the invention, the screw and / or the screw sleeve made of recyclable plastic, preferably polyamide, manufactures. This meets the requirements for environmental compatibility.

In weiterer Ausgestaltung der Erfindung sind die Schraubköpfe an ihren gegenseitig zugewandten Seiten zueinander im Wesentlichen planparallel ausgebildet. Hierdurch sind vorstehende Kanten vermieden, welche im Gebrauch eine Beschädigung der Muster bewirken könnten.In a further embodiment of the invention, the screw heads are formed on their mutually facing sides to each other substantially plane-parallel. As a result, protruding edges are avoided, which could cause damage to the pattern in use.

Hierdurch ist das Einbringen der Schraube in die Schraubhülse erleichtert.In development of the invention, in each case a receptacle for a screwing tool is introduced into the screw heads. As a result, the introduction of the screw is facilitated in the screw.

In Ausgestaltung der Erfindung weist die Durchgangsbohrung der Schraubhülse im Bereich des Innengewindes einen durchmesservergrößerten Abschnitt auf. Hierdurch ist die Stabilität der Vorrichtung erhöht, da nur im Bereich des Innengewindes für die Schraube eine Materialstärkenverjüngung erfolgt.In an embodiment of the invention, the through hole of the threaded sleeve in the region of the internal thread on an enlarged diameter portion. As a result, the stability of the device is increased, since only in the region of the internal thread for the screw material thickness taper occurs.

In Weiterbildung der Erfindung weist die Schraubhülse einen konisch ausgebildeten Abschnitt auf, der in den durchmesservergrößerten Bereich mündet. Hierdurch ist ein homogener Materialfluss für den Spritzgussvorgang geschaffen, plötzliche Materialstärkenverminderungen, die oftmals zu ungewollten Lunkern führen können, sind so vermieden. Weiterhin ist so im Bereich der Materialverjüngung eine erhöhte Flexibilität der Schraubhülse geschaffen, wodurch die Gefahr eines Belastungsbruchs vermindert ist. Vorteilhaft entspricht der maximale Innendurchmesser des konisch ausgebildeten Abschnitts im Wesentlichen dem Durchmesser des Innengewindes.In a further development of the invention, the threaded sleeve has a conically shaped section which opens into the diameter-enlarged region. hereby is created a homogeneous flow of material for the injection molding process, sudden material thickness reductions, which can often lead to unwanted voids are avoided. Furthermore, increased flexibility of the screw sleeve is thus created in the region of the material taper, whereby the risk of stress fracture is reduced. Advantageously, the maximum inner diameter of the conical section substantially corresponds to the diameter of the internal thread.
