Description
Die Erfindung betrifft einen Verschluß für Ringe oder topfförmige Gehäuse bestehend aus an beiden Enden eines plattenförmigen Halbzeugs abwechselnd vorhandenen Vorsprüngen und Ausnehmungen, die im zusammengefügten Zustand reißverschlußartig ineinandergreifen.The invention relates to a closure for rings or Pot-shaped housing consisting of a on both ends plate-shaped semi-finished goods alternately available Projections and recesses that are joined together Interlock condition like a zipper.
Gehäuse dieser Art sind beispielsweise aus der DE-OS 22 36 408 bekannt. Nach dem Biegevorgang liegen die beiden Kanten des Streifens aneinander und geben so beispielsweise einem in dem Gehäuse eingebauten Kleinmotor einen gewissen Schutz gegen Schmutz, Feuchtigkeit usw. Bei höheren Anforderungen an die Dichtigkeit des Gehäuses wird bisher das Gehäuse z. B. durch Überkleben des Spaltes zwischen den beiden Streifenkanten abgedichtet, was mit einem verhältnismäßig hohen Aufwand verbunden ist.Housings of this type are for example from DE-OS 22nd 36 408 known. After the bending process, the two lie Edges of the strip together and so give for example one built into the housing Small motor some protection against dirt, Moisture etc. With higher demands on the Tightness of the housing is the housing z. B. by pasting over the gap between the two Strip edges sealed, what with a relative high effort is connected.
Aus der US-PS 23 30 207 ist ein Verfahren zur Herstellung von Behältern aus gerolltem Blech bekannt. Dabei sind die Enden so zusammengeführt, daß sich keine glatte Oberfläche ergibt. Außerdem ist keine Spritzwassersicherheit gegeben.From US-PS 23 30 207 is a method for manufacturing of containers made of rolled sheet metal. Here are the Ends brought together in such a way that no smooth ones Surface results. Besides, there is none Splash-proof.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Ring oder ein Gehäuse der eingangs beschriebenen Art zu entwickeln, die eine hohe Dichtigkeit im Bereich der beiden Kanten und damit z. B. bei Gehäusen einen besseren Schutz gegen Umwelteinflüsse bieten als die herkömmlichen Gehäuse. The invention is therefore based on the object of a ring or to develop a housing of the type described at the outset, a high tightness in the area of the two edges and thus z. B. with housings better protection against Offer environmental influences than the conventional housing.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an beiden Enden des Halbzeugs die Vorsprünge und die Ausnehmungen im Querschnitt derart durchgehend komplementär stufenförmig ausgebildet sind, daß sich die Enden im zusammengefügten Zustand überlappen.This object is achieved in that at both ends of the semi-finished product the projections and the Recesses in cross section in such a way are complementary step-shaped that the Overlap ends when assembled.
Eine weitere Ausbildung der Erfindung besteht darin, daß die Vorsprünge un die Ausnehmungen zusätzlich abwechselnd treppenförmig, oben und unten, angeordnet sind.Another embodiment of the invention is that the projections and the recesses alternately are arranged in steps, above and below.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß ohne großen Aufwand, vor allem ohne Nacharbeit, eine gute Verbindung bei einem Ring bzw. ein praktisch dichtes Gehäuse geschaffen wird, ohne den kostengünstigen Weg zur Herstellung solcher Gehäuse zu verlassen.The advantages achieved with the invention exist especially in that without much effort, especially without rework, a good connection with a ring or a practically sealed housing is created without the inexpensive way to manufacture such housings too leave.
Die Erfindung wird anhand der Zeichnungen näher erläutert. Es zeigenThe invention is illustrated by the drawings explained. Show it
Fig. 1 und Fig. 2 bekannte Verschlüsse an einem Ring bzw. einer Gehäusewand, . 2-known fasteners on a ring or a casing wall Fig. 1 and Fig.
Fig. 3 ein nach der Erfindug gestaltetes Ende des Halbzeugs für eine Gehäusewand, Fig. 3 is a designed according to the invention entitled end of the preform for a housing wall,
Fig. 4 schematisch eine Gehäusewand mit der Verschlußstelle kurz vor Beendigung des Biegevorganges und Fig. 4 schematically shows a housing wall with the closure point shortly before the bending process and
Fig. 5 eine andere erfindungsgemäße Ausführung des Verschlusses. Fig. 5 shows another embodiment of the closure according to the invention.
In Fig. 1 ist mit 1 ein Halbzeug dargestellt, dessen eines Ende 2 einen schwalbenschwanzförmigen Vorsprung 3 und dessen anderes Ende 4 eine diesem Vorsprung 3 zugeordnete Ausnehmung 5 hat. Nach dem Zusammenbiegen des Halbzeugs 1 ist der schwalbenschwanzförmige Vorsprung 3 in die Ausnehmung 5 hineingedrückt. Dasselbe gilt im Prinzip für die Ausführung nach Fig. 2; die Vorsprünge 3 und die diesen zugeordneten Ausnehmungen 5 haben jedoch eine an dere Form.In Fig. 1, 1 is a semi-finished product, one end 2 of which has a dovetail-shaped projection 3 and the other end 4 of which has a recess 5 associated with this projection 3 . After the semifinished product 1 has been bent together, the dovetail-shaped projection 3 is pressed into the recess 5 . The same applies in principle to the embodiment according to FIG. 2; however, the projections 3 and the recesses 5 associated therewith have a different shape.
Bei diesen beiden bekannten Verschlüssen nach den Fig. 1 und 2 ist die Dichtig keit in manchen Anwendungsfällen aber ungenügend.In these two known closures according to FIGS . 1 and 2, the sealing speed is insufficient in some applications.
Werden die Enden 2 bzw. 4 des Halbzeugs 1, aus dem die Gehäusewand gebogen wird, jedoch gemäß Fig. 3 gestaltet, so er gibt sich eine praktisch dichte Gehäusewand; es ist eine stufenförmige Ausbildung der Enden 2 bzw. 4 vorhanden, die sich nach dem Zusammenbiegen überlappen, wie dies in Fig. 4 dargestellt ist. Dadurch ist eine Dichtfläche A bzw. A′ entstanden, die senkrecht zu den Kanten B und C bzw. B′ und C′ verläuft.If the ends 2 or 4 of the semifinished product 1 from which the housing wall is bent, however, are designed according to FIG. 3, so that there is a practically sealed housing wall; there is a step-like design of the ends 2 and 4 , which overlap after bending, as shown in FIG. 4. This creates a sealing surface A or A ' , which is perpendicular to the edges B and C or B' and C ' .
Soll neben einer hohen Dichtheit auch noch ein besonders stabiler Verschluß erreicht werden, so ist es zweckmäßig, zusätzlich ein Verschachteln der beiden Enden 2 und 4 vorzunehmen, wie das Fig. 5 zeigt: Den Dichtflächen A sind Dichtflächen A′ zugeordnet, die ab wechselnd, treppenförmig, oben und unten liegen. Die Enden B und B′ bzw. C und C′ können aufgrund der Elastizi tätseigenschaften des aus dem Halbzeug 1 geformten Ringes (Gehäusewand) nicht fest und bündig aneinanderliegen, jedoch sind die Flächen A und A′ aufeinandergeschoben und bilden so die eigentliche Dichtfläche. So entsteht ein Verschluß, der hohen Ansprüchen an die Dichtigkeit und Festigkeit bzw. Steifigkeit genügt.If, in addition to a high level of tightness, a particularly stable closure is also to be achieved, it is expedient to additionally nest the two ends 2 and 4 , as shown in FIG. 5: The sealing surfaces A are assigned sealing surfaces A ' , which alternate from step-like, lying above and below. The ends B and B ' or C and C' can due to the elasticity properties of the formed from the semi-finished 1 ring (housing wall) not tight and flush, but the surfaces A and A ' pushed together and thus form the actual sealing surface. This creates a closure that meets high demands on tightness and strength or rigidity.
