Description

Ring buchmechanik für Loseblattbücher, Briefordner u. dgl. Die Erfindung betrifft eine Ringbuchmechanik für Loseblattbücher, Briefordner u. dgl., bei der die Ringhälften in der Offen-und Schließstellung durch eine auf der Gelenkachse sitzende Feder verriegelt werden.Ring book mechanism for loose-leaf books, letter folders and the like. The invention relates to a ring binder mechanism for loose-leaf books, letter folders and the like the ring halves in the open and closed position by one on the hinge axis seated spring locked.

Es ist bekannt, bei Klemmechaniken, die um einen Bolzen scharnierartig klappbaren Klemmglieder mittels auf den Scharnierhülsen sitzenden Nocken gegen Federwirkung in der Offenstellung zu sichern. Auch bei Ringbuchmechaniken mit feststehenden und schwingbaren Ringhälften ist es bekannt, die letzteren verschiebbar auf der Scharnierwelle vorzusehen und sie in der geschlossenen und geöffneten Lage der Ordner durch dieselbe Feder zu sichern.It is known in clamping mechanisms that hinge around a bolt foldable clamping members by means of cams seated on the hinge sleeves against spring action secure in the open position. Even with ring binder mechanisms with fixed and swinging ring halves it is known, the latter slidable on the hinge shaft and provide them in the closed and open position of the folder through the same Secure spring.

Das Neue besteht nun darin, daß die bewegliche Gelenkleiste längs verschieblich auf dem Gelenkstift sitzt und die an den Gelenkhülsen in bekannter Weise vorgesehen zueinander versetzten Nocken abgerundete Kanten haben, so daß bei leichtem Druck gegen die schwingbare Gelenkleiste die Wirkung der Verriegelungsfeder überwunden wird und das Gelenk mit den Ringhälften in die Schließ-bzw. Offenstellung einschnappt. Es. genügt also nur ein Handgriff zur Betätigung der Mechanik.The new thing is that the movable joint bar is longitudinal slidably seated on the hinge pin and the known on the hinge sleeves Way provided offset cams have rounded edges, so that at light pressure against the pivoting joint bar, the effect of the locking spring is overcome and the joint with the ring halves in the closing or. Open position snaps into place. It. All that is needed is a movement of the hand to operate the mechanism.

in der Zeichnung ist die Erfindung in einem Ausführungsbeispiel veranschaulicht, und zwar zeigt Abb. i die geschlossene Stellung und Abb. z die geöffnete Lage der Mechanik. Die beiden Gelenkteile a und b tragen die Aufreihstifte c und d, die ringförmig oder auch anders gestaltet sein können. Gelenkleiste a ist fest mit der Einbanddecke e verbunden, während Gelenkleiste b zwecks Öffnens der Mechanik um den Gelenkstift i gekippt werden kann. Die Gelenkhülsen g, des Teiles a sowie die Hülsen k des Teiles b sind in an sich bekannter Weise mit zueinander versetzten Nocken i bzw. k versehen, die in neuartiger Weise schräg ansteigende Auflaufflächen besitzen. In einer Aussparung der Gelenkhülsen sitzt auf der Gelenkachse i die auf Druck beanspruchte Schraubenfeder f, die gegen die längs bewegliche Gelenkleiste b wirkt.In the drawing, the invention is illustrated in one embodiment, namely Fig. i shows the closed position and Fig. z shows the open position of the mechanism. The two joint parts a and b carry the alignment pins c and d, which can be ring-shaped or designed differently. Hinge strip a is firmly connected to the cover e, while the hinge strip b can be tilted around the hinge pin i for the purpose of opening the mechanism. The joint sleeves g of part a as well as the sleeves k of part b are provided in a manner known per se with cams i and k offset from one another, which in a novel way have inclined run-up surfaces. In a recess in the joint sleeves sits on the joint axis i the compression-loaded helical spring f which acts against the longitudinally movable joint bar b.

Die Wirkungsweise der beschriebenen Anordnung ist die folgende: In der Abb. i ist die geschlossene Stellung dargestellt. Die Aufreihstifte c und d sind geschlossen und werden in dieser geschlossenen Stellung durch die Druckwirkung der Schraubenfeder l' gehalten, die die Gelenkhülsen Bund /a gegeneinanderpreßt. Wird nun durch Druck auf die bewegliche Gelenkleiste b diese um die Achse/ gedreht, dann gleiten die schrägen Flächen der Nokken iund h aufeinander auf, und das bewegliche Gelenkteil wird in der Längsrichtung etwas verschoben, bis die Nocken i und k hintereinandergreifen (Abb. z). Die Druckfeder l hält die geöffneten Aufreihstifte c und d in dieser Stellung verriegelt, bis durch entgegengerichteten Druck gegen Gelenkleiste b die Federkraft überwunden und das Gelenk mit den Aufreihstiften nunmehr in die geschlossene Stellung selbsttätig übergeht (Abb. i) und durch die gleiche Federspannung auch in dieser Stellung verriegelt bleibt-Der Vorteil der neuen Vorrichtung besteht in der Vereinfachung gegenüber den bekannten Einrichtungen. Durch nur einen Fingerdruck gegen die Gelenkleiste b wird die Mechanik geöffnet und geschlossen, wobei in beiden Stellungen eine selbsttätige Verriegelung durch ein und dasselbe Federorgan erfolgt. _The mode of operation of the arrangement described is as follows: The closed position is shown in Fig. I. The alignment pins c and d are closed and are held in this closed position by the pressure action of the helical spring 1 'which presses the joint sleeves B and / a against one another. If the movable joint bar b is now rotated around the axis / by pressing it, the inclined surfaces of the cams i and h slide on each other and the movable joint part is shifted slightly in the longitudinal direction until the cams i and k engage one behind the other (Fig ). The compression spring l holds the opened alignment pins c and d locked in this position until the spring force is overcome by opposing pressure against the joint bar b and the joint with the alignment pins now automatically changes into the closed position (Fig. I) and also into remains locked in this position-The advantage of the new device consists in the simplification compared to the known devices. The mechanism is opened and closed by just pressing a finger against the joint bar b, with automatic locking by one and the same spring element taking place in both positions. _
