Description

Die Erfindung betrifft einen Klemmverschluss zum lösbaren Verbinden der Schliesslasche von Etuis, Schreibmappen od.dgl. mit dem Hauptkörper derartiger Gebilde, mit einem eine Feder aufweisenden Unterteil und einem Oberteil, welches beim Zusammendrücken von Oberteil und Unterteil mit der Feder in lösbaren Rasteingriff kommt, wobei das Unterteil eine mit auf einem Kreisumfang angeordneten, zwei einander gegenüberliegende Stege einschliessenden Vertiefungen versehene Basisplatte, eine mit den Vertiefungen entsprechenden Ansätzen versehene, durch Einpressen der Ansätze in die Vertiefungen mit der Basisplatte verbindbare, eine im Bereich der Stege geschlitzte Kappe sowie eine geschlitzte Ringfeder mit zwei einander gegenüberliegenden Umfangsvorsprüngen aufweist, welche in den Stegbereichen nach dem Zusammenbau des Unterteils federnd über den Aussenumfang der Kappe radial vorstehen, das Oberteil eine Klemmplatte mit einer dem Aussendurchmesser der Kappe im wesentlichen entsprechenden Kreisöffnung hat und an der dem Unterteil zugewandten Öffnungskante ein Ringvorsprung zum Eindrücken der Umfangsvorsprünge der Ringfeder und zum Einrasten zwischen diesen und der Basisplatte vorgesehen ist.The invention relates to a clamp closure for releasably connecting the closure flap of cases, writing cases or the like. with the main body of such structures, with a lower part having a spring and an upper part which comes into releasable locking engagement with the spring when the upper part and lower part are pressed together, the lower part being provided with a base plate arranged on a circular circumference and enclosing two opposing webs, a lugs corresponding to the recesses, which can be connected to the base plate by pressing the lugs into the recesses, a slotted cap in the area of the webs and a slotted ring spring with two mutually opposite circumferential projections which resiliently over the in the web areas after the assembly of the lower part Radially project the outer circumference of the cap, the upper part has a clamping plate with a circular opening substantially corresponding to the outer diameter of the cap and an annular projection on the opening edge facing the lower part for pressing in the circumferential projections Ring spring and is provided for snapping between them and the base plate.

Die DE-B 2 738 122 betrifft einen Klemmverschluss, bei dem die Basisplatte des Unterteils mit vier auf einem Kreisumfang angeordneten, paarweise zwei einander gegenüberliegende Stege einschliessenden Durchbrechungen versehen ist. Weiterhin weist das Unterteil beim Klemmverschluss nach der DE-B 2 738 122 eine mit vier den Durchbrechungen der Basisplatte entsprechenden Ansätzen versehene Kappe auf, die durch Einpressen der Ansätze in die Durchbrechungen mit der Basisplatte verbindbar ist. Die Kappe hat ausserhalb des Bereiches der Stege eine teilzylindrische Umfangswand mit geringerer Höhe als die Ansätze, wobei die Umfangswand zwischen jeweils zwei benachbarten, eng nebeneinanderliegenden Ansätzen bis zur Deckelfläche der Kappe hin durchbrochen ist. Durch diese Durchbrechungen treten die Umfangsvorsprünge einer in die Kappe eingesetzten, geschlitzten Ringfeder aus, so dass in den Stegbereichen nach dem Zusammenbau des Unterteils diese Umfangsvorsprünge radial über den Aussenumfang der Kappe federnd hervorstehen. Das Oberteil des Klemmverschlusses weist eine Klemmplatte auf, die eine dem Durchmesser der Kappe im wesentlichen entsprechende Kreisöffnung besitzt, wobei an der dem Unterteil zugewandten Öffnungskante ein Ringvorsprung zum Eindrücken der Umfangsvorsprünge der Ringfeder zum Einrasten zwischen diesen und der Basisplatte vorgesehen ist.DE-B 2 738 122 relates to a clamp closure, in which the base plate of the lower part is provided with four openings arranged on a circumference and in pairs enclosing two opposing webs. Furthermore, the lower part of the clamp closure according to DE-B 2 738 122 has a cap provided with four lugs corresponding to the openings in the base plate, which can be connected to the base plate by pressing the lugs into the openings. Outside the area of the webs, the cap has a partially cylindrical peripheral wall with a lower height than the lugs, the peripheral wall being broken through between two adjacent, closely adjacent lugs up to the cover surface of the cap. Through these perforations, the circumferential projections of a slotted ring spring inserted into the cap emerge, so that in the web areas after the assembly of the lower part, these circumferential projections protrude radially beyond the outer circumference of the cap. The upper part of the clamp closure has a clamping plate which has a circular opening which essentially corresponds to the diameter of the cap, an annular projection being provided on the opening edge facing the lower part for pressing in the peripheral projections of the annular spring for latching between the latter and the base plate.

Der bekannte Klemmverschluss ist im praktischen Gebrauch äusserst bequem und zuverlässig zu handhaben. Allerdings haben sich insofern Nachteile gezeigt, als die vier schmalen Ansätze der Kappe unter extremen Beanspruchungen abbrechen können, so dass die Verbindung zwischen Kappe und Basisplatte teilweise in unvorteilhafter Weise lösbar bzw. beschädigbar ist.The known clamp closure is extremely convenient and reliable to handle in practical use. However, there have been disadvantages in that the four narrow lugs of the cap can break off under extreme stress, so that the connection between the cap and the base plate can be detached or damaged in an unfavorable manner.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Klemmverschluss der eingangs genannten Art dahingehend weiterzubilden, dass eine zuverlässige Befestigung der Kappe auf dem Basisteil und damit eine sichere Aufnahme der Feder des Klemmverschlusses gewährleistet ist.The present invention is therefore based on the object of developing a clamp closure of the type mentioned at the outset in such a way that a reliable fastening of the cap to the base part and thus a secure reception of the spring of the clamp closure is ensured.

Erfindungsgemäss wird diese Aufgabe bei einem Klemmverschluss zum lösbaren Verbinden der Schliesslasche von Etuis, Schreibmappen od. dgl. dadurch gelöst, dass die Vertiefungen der Basisplatte aus zwei Nuten bestehen; und dass die Ansätze aus den beiden Hälften der ausserhalb der Stegbereiche teilzylindrisch ausgebildeten Umfangswand der Kappe selbst bestehen.According to the invention, this object is achieved in the case of a clamp closure for releasably connecting the closing flap of cases, writing cases or the like in that the depressions in the base plate consist of two grooves; and that the lugs consist of the two halves of the peripheral wall of the cap itself, which is partially cylindrical outside the web regions.

Bevorzugte Ausführungsformen der Erfindung zeichnen sich dadurch aus, dass die Ansätze der Kappe reibschlüssig in den Nuten der Basisplatte festgehalten sind und/oder die Kappe mittels der in den Nuten der Basisplatte befestigten Ansätze mit der Basisplatte verbunden ist, wobei letztere Ausgestaltung noch dadurch fortgebildet ist, dass die Kappe mittels der Ansätze in den Nuten der Basisplatte verschweisst ist oder dass die Ansätze in den Nuten fest eingeklebt sind.Preferred embodiments of the invention are characterized in that the lugs of the cap are held in the grooves of the base plate with a friction fit and / or the cap is connected to the base plate by means of the lugs fastened in the grooves of the base plate, the latter embodiment being further developed by that the cap is welded by means of the lugs in the grooves of the base plate or that the lugs are firmly glued into the grooves.

Erfindungsgemäss wird also der Verbindungsbereich zwischen Basisplatte und Kappe dadurch verbessert, dass in der Basisplatte zwei fast halbkreisförmige Nuten vorgesehen sind, in die zwei der Form dieser Nuten entsprechende, ebenfalls fast halbkreisförmige Ansätze der Kappe einsteckbar sind, wobei die Umfangsvorsprünge der in der Kappe befindlichen Ringfeder durch die einander gegenüberliegenden Durchbrechungen in der zylindrischen Seitenwand der Kappe zwischen den beiden, fast halbkreisförmigen Ansätzen der Kappe über den zwischen den fast halbkreisförmigen Nuten stehengelassenen Stegen der Basisplatte aus der Kappe herausragen, wodurch der Klemmeingriff mit der Klemmplatte ermöglicht wird. Insgesamt ergibt sich, dass die fast halbkreisförmigen Ansätze der Kappe äusserst stabil und beim normalen Gebrauch nicht abzubrechen sind, so dass eine zuverlässige und feste Verbindung zwischen Kappe und Basisplatte erreicht wird.According to the invention, the connection area between the base plate and cap is thus improved in that two almost semicircular grooves are provided in the base plate, into which two approaches of the cap, which are also almost semicircular and corresponding to the shape of these grooves, can be inserted, the circumferential projections of the ring spring located in the cap protrude from the cap through the opposite openings in the cylindrical side wall of the cap between the two, almost semicircular lugs of the cap over the webs of the base plate left between the almost semicircular grooves, whereby the clamping engagement with the clamping plate is made possible. Overall, it follows that the almost semicircular approaches of the cap are extremely stable and cannot be broken off during normal use, so that a reliable and firm connection between the cap and the base plate is achieved.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den Ansprüchen und aus der nachfolgenden Beschreibung, in der ein Ausführungsbeispiel anhand der Zeichnung im einzelnen erläutert ist. Dabei zeigt:

Die dargestellte Basisplatte 22 besitzt einen Zentralteil 6 und einen den Zentralteil 6 bis auf eine Seite umfangsmässig umgebenden, schulterartig abgesetzten Umfangsrand 8. Die Basisplatte 22 ist mit zwei auf einem Kreisumfang angeordneten, zwei einander gegenüberliegenden Stege 10, 12 einschliessenden, fast halbkreisförmigen Nuten 14, 16 versehen, die jeweils einen im wesentlichen rechteckigen Querschnitt aufweisen.The embodiment of the base plate 22 shown in FIG. 1 is provided as a lower part for cases for writing instruments, the case provided with the lower part being able to accommodate two writing instruments. The illustrated base plate 22 has a central part 6 and a shoulder-like circumferential edge 8 surrounding the central part 6 up to one side circumferentially. 16 provided, each having a substantially rectangular cross section.

In Fig. 2 ist eine Kappe 34 dargestellt, die eine Umfangswand besitzt, von der sich zwei Nuten 14, 16 entsprechende, ebenso fast halbkreisförmige Ansätze 24, 26 senkrecht zur Deckelfläche 33 der Kappe 34 erstrecken. Zwischen den fast halbkreisförmigen Ansätzen 24, 26 ist die Umfangswand 32 auf zwei genau gegenüberliegenden Seiten bis zur Kappenfläche 33 hin durchbrochen. Hier treten die Umfangsvorsprünge 38, 40 der in die Kappe 34 einzusetzenden, in Fig. 3 dargestellten Ringfeder 36 hindurch. Die Ringfeder 36 ist dabei nicht als Vollring ausgebildet, sondern vielmehr an einer Stelle 37 des Umfangs durchbrochen, damit sie bei auf die'Umfangsvorsprünge 38, 40 wirkenden Kräfte zusammendrückbar ist, so dass sich die Umfangsvorsprünge 38, 40 nach einwärts zurückziehen können.FIG. 2 shows a cap 34 which has a peripheral wall, from which two grooves 14, 16 corresponding, also almost semicircular extensions 24, 26 extend perpendicular to the lid surface 33 of the cap 34. Between the almost semicircular shoulders 24, 26, the circumferential wall 32 is broken through on two exactly opposite sides up to the cap surface 33. The circumferential projections 38, 40 of the annular spring 36 to be inserted into the cap 34 and shown in FIG. 3 pass through here. The annular spring 36 is not designed as a full ring, but rather perforated at a point 37 on the circumference, so that it can be compressed under forces acting on the circumferential projections 38, 40, so that the circumferential projections 38, 40 can retract inwards.

Zur Anpassung der zum Schliessen bzw. Öffnen des Klemmverschlusses aufzuwendenden Kräfte werden die Umfangsvorsprünge im dargestellten Ausführungsbeispiel einseitig durch Abschrägung 39, 41 vom Rand der Ringfeder 36 her zu ihrem Ende hin abgeschrägt.In order to adapt the forces to be used for closing or opening the clamp closure, the circumferential projections in the exemplary embodiment shown are chamfered on one side by chamfering 39, 41 from the edge of the annular spring 36 to its end.

Die Darstellung der Fig. 4 zeigt das aus Basisplatte, Kappe 34 und Ringfeder 36 zusammengesetzte Unterteil. Die sich aus der Kappe heraus erstreckenden Umfangsvorsprünge 38, 40 der Ringfeder 36 sind deutlich erkennbar. Zur Befestigung sind dabei die unteren Enden 25, 27 der Ansätze 24, 26 in den Nuten 14, 16 fest verschweisst.4 shows the lower part composed of base plate, cap 34 and annular spring 36. The circumferential projections 38, 40 of the ring spring 36 extending out of the cap are clearly recognizable. For fastening, the lower ends 25, 27 of the lugs 24, 26 are firmly welded in the grooves 14, 16.

Eine Klemmplatte 42 des Oberteils des erfindungsgemässen Klemmverschlusses ist in Fig. 5 dargestellt, wobei die Klemmplatte 42 eine im wesentlichen dem Durchmesser der Kappe 34 entsprechende Kreisöffnung 44 aufweist, an deren dem Unterteil zugewandten Öffnungskante sich ein Ringvorsprung 46 zum Eindrücken der Umfangsvorsprünge 38, 40 der Ringfeder 36 und zum Einrasten zwischen diesen und der Basisplatte 22 befindet. Das in Fig. 5 dargestellte Ausführungsbeispiel der Klemmplatte 42 ist im wesentlichen halbkreisförmig ausgebildet und zum halbkreisförmigen Umfang hin leicht abgeflacht, während sich am geraden Ende der Klemmplatte 42 sich ein Ansatz 48 mit geringerer Dicke als die Klemmplatte 42 befindet, der, ebenso wie der Umfangsrand des Unterteils, mit Nähösen 50 versehen ist, mittels derer jeweils Oberteil und Unterteil mit Etuimaterial, beispielsweise Leder oder lederähnlichem Kunststoffmaterial, vernähbar sind. Zur praktischen Verwendung wird das Unterteil und das Oberteil des erfindungsgemässen Klemmverschlusses mittels der Nähösen 50 in ein Etui derart eingenäht, dass zum Verschliessen des Etuis das mit einer Lasche des Etuis verbundene Oberteil auf das Unterteil fest aufdrückbar ist, so dass die Umfangsvorsprünge 38, 40 der Ringfeder 36 den Ringvorsprung 46 der Kreisöffnung 44 der Klemmplatte 42 des Oberteils hintergreifen.
