Die Erfindung betrifft eine Ordnermechanik mit einer aus Metallblech bestehenden Grundplatte, zwei im Abstand voneinander an der Grundplatte senkrecht überstehenden Aufreihstiften, einem aus gebogenem Metalldraht bestehenden, einen mittig gekröpften Lagersteg und zwei an den Enden des Lagerstegs abgebogene Umlegeschenkel aufweisenden Umlegebügel, zwei unter Bildung eines Schwenklagers für den Umlegebügel im Abstand voneinander und von den Aufreihstiften aus der Grundplatte herausgestanzten und von der Seite der Aufreihstifte her um je einen an den benachbarten Umlegeschenkeln angrenzenden ungekröpften Teil des Lagerschenkels gerollte Lagerzungen, und einem an einem Lagerbock der Grundplatte angelenkten, auf dem gekröpften Teil des Lagerstegs einwirkenden Betätigungshebel, mittels dessen der Umlegebügel zwischen einer Offenstellung und einer mit den Aufreihstiften gekuppelten Schließstellung entgegen der Kraft einer Rückstellfeder begrenzt verschwenkbar ist.The invention relates to a folder mechanism with a base plate made of sheet metal, two row pins protruding vertically from one another on the base plate, a bent metal wire, a cranked bearing web and two turning arms bent at the ends of the bearing web, two folding arms, two forming a pivot bearing for the folding bracket at a distance from each other and punched out of the base plate by the aligning pins and from the side of the aligning pins by one non-cranked part of the bearing leg adjacent to the adjacent deflecting legs, and one pivoted to a crank block of the base plate, on the cranked part of the Actuating lever acting on the bearing web, by means of which the folding bracket can be pivoted to a limited extent against the force of a return spring between an open position and a closed position coupled with the aligning pins.
Ordnermechaniken dieser Art werden in Briefordnern eingesetzt, die einen Ordnerrücken sowie je einen am Ordnerrücken angelenkten Vorder- und Rückdeckel aufweisen. Die Ordnermechanik wird hierbei mit ihrer Grundplatte in der Nähe des Ordnerrückens am Rückendeckel angenietet oder in vormontierte Einschiebeplatten eingeschoben. Letzteres erfordert eine geschlossene Grundplatte mit etwa rechteckigem Umriß. Um eine sichere Lagerung des Umlegebügels zu gewährleisten, wird bei bekannten Ordnermechaniken vorgeschlagen, die Lagerzungen mit einem Umschlingungswinkel von mehr als 270° auf die ungekröpften Lagerteile aufzurollen. Das Aufrollen erfolgt im Zuge der Montage des Umlegebügels, wozu eine exakte Fixierung des Bügels gegenüber der Grundplatte erforderlich ist, da sonst die Lagerstelle nicht exakt definiert wäre. Da der Rollvorgang eine Querkraft auf den Bügel ausübt, ist die gegenseitige Fixierung des Umlegebügels und der Grundplatte mit fertigungstechnischen Schwierigkeiten verbunden.Folder mechanisms of this type are used in letter folders, which have a folder spine and a front and back cover hinged to the folder spine. The folder mechanism is riveted to the back cover with its base plate near the folder back or inserted into pre-assembled slide-in plates. The latter requires a closed base plate with an approximately rectangular outline. In order to ensure secure storage of the folding bracket, it is proposed in known folder mechanisms to roll up the bearing tongues with a wrap angle of more than 270 ° onto the non-cranked bearing parts. The reeling takes place in the During the assembly of the folding bracket, for which an exact fixation of the bracket relative to the base plate is required, since otherwise the bearing point would not be exactly defined. Since the rolling process exerts a transverse force on the bracket, the mutual fixing of the folding bracket and the base plate is associated with manufacturing difficulties.
Weiter ist es bei einer Ordnermechanik mit einer aus Metallblech bestehenden Grundplatte an sich bekannt (GB-A-1 112 594), zwei unter Bildung eines Schwenklagers für den Umlegebügel im Abstand voneinander aus der Grundplatte herausgestanzte und senkrecht hochgebogene Lagerzungen vorzusehen, die je einen der ungekröpften Teile des Lagerstegs auf der Seite des benachbarten Längsseitenrands hintergreifen. An ihrer Oberseite sind die Lagerzungen in Richtung Aufreihstifte um etwa 90° so gebogen, daß die Lagerstege unter die abgebogenen Lagerzungen einrastbar sind.Furthermore, it is known in a file mechanism with a base plate made of sheet metal (GB-A-1 112 594) to provide two vertically bent bearing tongues punched out from the base plate at a distance from one another to form a pivot bearing for the folding bracket, each of which Reach behind the cranked parts of the bearing web on the side of the adjacent longitudinal side edge. On their upper side, the bearing tongues are bent in the direction of the alignment pins by approximately 90 ° in such a way that the bearing webs can be snapped under the bent bearing tongues.
Der Erfindung liegt die Aufgabe zugrunde, eine Ordnermechanik sowie ein Verfahren zur Herstellung der Ordnermechanik der eingangs angegebenen Art zu entwickeln, womit eine einfache Anbringung des Bügellagers möglich und trotzdem eine hohe Lagegenauigkeit des Umlegebügels gewährleistet ist.The invention is based on the object of developing a folder mechanism and a method for producing the folder mechanism of the type specified at the outset, with which a simple attachment of the bracket bearing is possible and nevertheless a high positional accuracy of the folding bracket is ensured.
Zur Lösung dieser Aufgabe werden gemaß der Erfindung die im Patentanspruch 1 angegebenen Merkmale vorgeschlagen. Weitere vorteilhafte Ausgestaltungen udn Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.To achieve this object, the features specified in claim 1 are proposed according to the invention. Further advantageous refinements and developments of the invention result from the dependent claims.
Die Erfindung geht von dem Gedanken aus, daß die bei der Herstellung des Schwenklagers notwendige Lagefixierung des Umlegebügels am besten durch ein in definiertem Abstand von den Aufreihstiften an der Grundplatte selbst angeordnetes Gegenlager für den Umlegebügel bewerkstelligt werden kann. Um dies zu erreichen, wird gemäß der Erfindung vorgeschlagen, daß das Schwenklager zusätzlich zwei aus der Grundplatte ausgestanzte und senkrecht hochgebogene Gegenlagerzungen aufweist, die je einen der ungekröpften Teile des Lagerstegs auf der in Rollrichtung gegenüberliegenden Seite der Lagerzungen hintergreifen. Um einen zuverlässigen Anschlag für den Umlegebügel zu gewährleisten, sollte der über die Grundplatte überstehende Teil der Gegenlagerzunge länger als der Radius und kürzer als der Durchmesser des den Umlegebügel bildenden Metalldrahtes sein. Da das Gegenlager einen Teil des Schwenklagers bildet, der den Lagersteg um etwa 90° umschlingt, reicht es aus, wenn der Umschlingungswinkel der Lagerzungen um den Lagersteg nur noch 150 - 200°, vorzugsweise 180 - 190° beträgt. Dies ist sowohl in fertigungstechnischer Hinsicht als auch im Hinblick auf die erreichbare Lagegenauigkeit von Vorteil.The invention is based on the idea that the position fixing of the folding bracket necessary in the manufacture of the pivot bearing can best be accomplished by a counter bearing for the folding bracket itself which is arranged on the base plate at a defined distance from the alignment pins. To achieve this, it is proposed according to the invention that the pivot bearing additionally has two counterbearing tongues punched out of the base plate and bent up vertically, each of which engages behind one of the non-cranked parts of the bearing web on the opposite side of the bearing tongues in the rolling direction. In order to ensure a reliable stop for the folding handle, the part of the counter bearing tongue protruding over the base plate should be longer than that Radius and shorter than the diameter of the metal wire forming the folding bracket. Since the counter bearing forms part of the pivot bearing, which wraps around the bearing web by approximately 90 °, it is sufficient if the wrap angle of the bearing tongues around the bearing web is only 150-200 °, preferably 180-190 °. This is advantageous both in terms of production technology and in terms of the positional accuracy that can be achieved.
Aus Gründen der Materialfestigkeit und der Lagegenauigkeit ist es weiter von Vorteil, wenn die einander benachbarten Lagerzungen und Gegenlagerzungen in Richtung Schwenkachse versetzt gegeneinander angeordnet sind, wobei der gegenseitige Abstand zwischen den Lagerzungen zweckmäßig größer als der der Gegenlagerzungen ist.For reasons of material strength and positional accuracy, it is also advantageous if the adjacent bearing tongues and counter-bearing tongues are arranged offset with respect to one another in the direction of the pivot axis, the mutual distance between the bearing tongues advantageously being greater than that of the counter-bearing tongues.
Zur Herstellung der vorbeschriebenen Ordnermechanik wird gemäß der Erfindung vorgeschlagen, daß zunächst die Gegenlagerzungen ausgestanzt und an der Grundplatte senkrecht hochgebogen werden, und daß anschließend der Umlegebügel mit seinen ungekröpften Lagerstegteilen gegen die Gegenlagerzungen auf der Grundplatte angelegt wird, bevor die Lagerzungen um die ungekröpften Lagerstegteile gerollt werden. Ein weiterer fertigungstechnischer Vorteil kann dadurch erzielt werden, wenn zunächst die ausgestanzten Gegenlagerzungen und die ausgestanzten Lagerzungen gleichzeitig oder nacheinander an der Grundplatte senkrecht hochgebogen werden, der Umlegebügel mit seinen ungekröpften Lagerteilen in den zwischen den hochgebogenen Lagerzungen und Gegenlagerzungen gebildeten Zwischenraum unter Anlage gegen die Gegenlagerzungen eingelegt wird und erst danach die Lagerzungen um die ungekröpften Lagerstegteile gerollt werden.To produce the folder mechanism described above, it is proposed according to the invention that the counter-bearing tongues are first punched out and bent upwards vertically on the base plate, and that the folding bracket with its non-cranked bearing web parts is then placed against the counter-bearing tongues on the base plate before the bearing tongues are rolled around the non-cranked bearing web parts become. A further advantage in terms of production can be achieved if the punched-out counter-bearing tongues and the punched-out bearing tongues are first bent vertically at the same time or one after the other on the base plate, and the folding bracket with its non-cranked bearing parts is placed in the space formed between the bent-up bearing tongues and counter-bearing tongues under abutment against the counter-bearing tongues is and only afterwards the bearing tongues are rolled around the non-cranked bearing web parts.
