Abstract

Closure for rings or pot-shaped housings made of bent strips which are closed by a seam, one edge of the strip having projections and the other edge of the strip having recesses assigned to these projections. The fact that the two edges of the strip each have a step which overlaps when bent results in a ring or a housing wall which no longer requires expensive sealing. In the event of high requirements of the leak-tightness and strength of the ring or housing wall, the two edges of the strip are designed such that the sealing faces are arranged alternately in the form of steps at the top and the bottom.

Description

BESCHREIBUNG DESCRIPTION

Verschluß für Ringe oder topfförmige Gehäuse Die Erfindung betrifft sowohl Ringe (ohne Boden) als auch topfförmige Gehäuse, die einen Boden und eine aus einem gebogenen Streifen bestehende Gehäusewand aufweisen, wobei die eine Kante des Streifens Vorsprünge sowie die andere Kante des Streifens diesen Vorsprüngen zugeordnete Ausnehmungen hat. Closure for rings or cup-shaped housings The invention relates to both rings (without bottom) and cup-shaped housings that have a bottom and a have housing wall consisting of a curved strip, one edge of the strip projections as well as the other edge of the strip these projections has associated recesses.

Gehäuse dieser Art sind beispielsweise aus der DE-PS 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.Housing of this type are known from DE-PS 22 36 408, for example. After the bending process, the two edges of the strip are against each other and give for example a small motor built into the housing a certain protection against dirt, moisture, etc.

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.With higher demands on the tightness of the housing is so far the housing e.g. by gluing over the gap between the two strip edges sealed, which is associated with a relatively high effort.

Der Erfindung liegt 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 based on the object of a ring or a housing of the type described above to develop a high degree of tightness in the area the two edges and thus, for example, better protection against environmental influences in the case of housings offer than the conventional housing.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die beiden Kanten des Streifens je eine sich im gebogenen Zustand überlappende Stufe aufweisen.This object is achieved according to the invention in that the two Edges of the strip each have an overlapping step in the bent state.

Nach einer weiteren Ausbildung der Erfindung werden die beiden Kanten des Streifens so verschachtelt gestaltet, daß die Dichtflächen abwechselnd, treppenförmig, oben und unten angeordnet sind.According to a further embodiment of the invention, the two edges of the strip designed so that the sealing surfaces alternate, step-shaped, are arranged 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 are in particular: that without much effort, especially without rework, a good connection with one Ring or a practically tight housing is created without the cost-effective Way to leave such housing.

Die Erfindung wird anhand der Zeichnungen näher erläutert.The invention is explained in more detail with reference to the drawings.

Es zeigen Fig. 1 und 2 bekannte Verklammerungen eines Ringes bzw.1 and 2 show known brackets of a ring or

der Gehäusewand, Fig 3 eine nach der Erfindung gestaltete Kante des Streifens für eine Gehäusewand, Fig. 4 schematisch eine Gehäusewand an der Trennstelle kurz vor Beendigung des Biegevorganges und Fig. 5 eine andere erfindungsgemäße Ausführung. the housing wall, FIG. 3 shows an edge of the designed according to the invention Strip for a housing wall, Fig. 4 schematically a housing wall at the separation point shortly before the end of the bending process and FIG. 5 shows another embodiment according to the invention.

In Fig. 1 ist mit 1 ein Streifen angedeutet, dessen eine Kante 2 einen schwalbenschwanzförmigen Lappen 3 (Vorsprung) und dessen zweite Kante 4 eine diesem Lappen 3 zugeordnete Ausnehmung 5 hat. Nach dem Zusammenbiegen des Streifens 1 ist der schwalbenschwanzförmige Lappen 3 in die Ausnehmung 5 hineingedrückt. Dasselbe gilt im Prinzip für die Ausführung nach Fig. 2; lediglich die Lappen 3 und die diesen zugeordneten Ausnehmungen 5 haben eine andere Form.In Fig. 1, 1 indicates a strip, one edge 2 of which is a dovetail-shaped tab 3 (projection) and its second edge 4 a this Lobe 3 has associated recess 5. After bending the strip 1 is the dovetail-shaped tab 3 is pressed into the recess 5. The same thing applies in principle to the embodiment according to FIG. 2; only the tabs 3 and these associated recesses 5 have a different shape.

Bei den beiden bekannten Verklammerungen nach den Fig. 1 und 2 des Streifens 1 bzw. der Gehäusewand ist die Dichtheit- in manchen Anwendungsfällen ungenügend.In the two known brackets according to FIGS. 1 and 2 of the Strip 1 or the housing wall is the tightness - in some applications insufficient.

Werden die Kanten 2 bzw. 4 des Streifens 1, aus dem die Gehäusewand gebogen wird, gemäß Fig. 3 gestaltet, so ergibt sich eine praktisch dichte Gehäusewand; es ist eine stufenförmige Ausbildung der Kanten 2 bzw. 4 vorhanden, die sich nach dem Zusammenbiegen überlappen, wie das in Fig. 4 angedeutet ist. Dadurch ist eine Dichtfläche A bzw. A' entstanden, die senkrecht zu den Kanten 8 und C bzw. 8' und C' verläuft.The edges 2 and 4 of the strip 1, from which the housing wall is bent, designed according to FIG. 3, the result is a practically tight housing wall; there is a stepped formation of the edges 2 and 4, which follow overlap the bending, as indicated in FIG. This is a Sealing surface A and A 'emerged, which are perpendicular to the edges 8 and C or 8' and C 'runs.

Soll neben einer hohen Dichtheit ein stabiler Verschluß bzw. eine stabile Verklammerung erreicht werden, so ist es zweckmäßig, zusätzlich ein Verschachteln der beiden Kanten 2 und 4 vorzunehmen, wie das Fig. 5 zeigt: den Dichtflächen A sind Dichtflächen A' zugeordnet, die abwechselnd, treppenförmig, oben und unten liegen. Die Kanten B und B' bzw. C und C' können aufgrund der Elastizitätseigenschaften des aus dem Streifen 1 geformten Ringes (Gehäusewand) nicht fest und bündig aneinanderliegen, während die Flächen A und A' aufeinandergeschoben werden und so die eigentliche Dichtfläche bilden. So entsteht ein Ring bzw. eine Gehäusewand, die hohen Ansprüchen an die Dichtheit und Festigkeit bzw. Steifigkeit genügt.Should a stable closure or a stable interlocking can be achieved, so it is advisable to also use nesting of the two edges 2 and 4, as shown in FIG. 5: the sealing surfaces A. are assigned sealing surfaces A ', which are alternating, step-shaped, above and below lie. The edges B and B 'or C and C' can due to the elasticity properties of the ring (housing wall) formed from the strip 1 do not lie firmly and flush against one another, while the surfaces A and A 'are pushed together and so the actual Form sealing surface. This creates a ring or a housing wall that meets high demands suffices for tightness and strength or rigidity.
