A further component of the housing or chassis swivelably arranged on the stationary component is so engaged that the cross part of the T-shaped additional piece (2) projecting through the recess in the angle piece (1) is swivelable between the arms of the angle piece.

Description

Aus Blechteilen bestehendes SchwenklagerSwivel bearing made from sheet metal parts

Die Erfindung bezieht sich auf ein aus Blechteilen bestehendes Schwenklager für Gehäuse, Chassisteile oder dgl..The invention relates to a pivot bearing made of sheet metal parts for housing, chassis parts or the like.

Zur Vereinfachung der Wartung und Prüfung von in Gestellzihmen oder Gehäusen untergebrachten elektrischen Schaltungsteilen, wie z.B. mit elektrischen Bauelementen bestückte Leiterplatten, selbständige Baueinheiten oder dgl. ist es zweckmäßig, diese schwenkbar anzuordnen, um auch im normalen Einbauzustand abgekehrte Schaltungsteile zugänglich zu machen. Sind derartige Schaltungsteile auf das Abführen von Verlustwärme nicht nur durch Konvektion sondern auch durch direkte Ableitung an größere metallische Außenflächen oder Rahmen der Gehäuse oder Gestelle angewiesen, dann muß die Wärmeableitung über Drehlager mit möglichst großer Flächenberührung der Drehlagerteile erfolgen. Übliche Scharniere können diese Forderung im allgemeinen nicht ausreichend erfüllen.To simplify the maintenance and testing of in rack frames or Housings housed electrical circuit parts, such as with electrical Components assembled circuit boards, stand-alone units or the like. It is expedient to arrange this pivotable in order to turn away even in the normal installed state To make circuit parts accessible. Are such circuit parts on the dissipation of heat loss not only through convection but also through direct dissipation dependent on larger metallic outer surfaces or frames of the housings or racks, then the heat must be dissipated via pivot bearings with the greatest possible surface contact of the pivot bearing parts. Usual hinges can meet this requirement in general not sufficiently meet.

Der Erfindung liegt die Aufgabe zugrunde, ein Schwenklager der eingangs genannten Art anzugeben, das nicht nur eine gut Wärmeableitung gewährleistet, sondern auch kostengünstig herstellbar ist.The invention is based on the object of a pivot bearing of the initially specified type, which not only ensures good heat dissipation, but can also be produced inexpensively.

Gemäß der Erfindung wird diese Aufgabe durch die den Patentanspruch 1 kennzeichnenden MerKmale gelöst.According to the invention, this object is achieved by the claim 1 characteristic features solved.

Ein besonderer Vorteil der erfindungsgemäßen Lösung besteht einmal darin, daß die Wärmeableitung über das Schwenklager in einfacher Weise durch Vergrößerung des T-förmigen Ansatzstückes beeinflußt werden kann. Zum anderen kann das Schwenklager bei entsprechender Ausgestaltung der Gehäuse- bzw. Vorrichtungsteile ohne zusätzlichen Bauteileaufwand verwirklicht werden, indem das als Aufnahme für das T-förmige Ansatzstück vorgesehene Winkelstück mit Ausnehmung z.B. Teil eines Gehäuses oder Gestellrahmens und das T-förmige Ansatzstück z.B. Teil eines elektrische Baugruppen oder dgl. aufnehmenden Trägers sind.There is one particular advantage of the solution according to the invention in that the heat dissipation via the pivot bearing in a simple manner by enlarging of the T-shaped extension piece can be influenced. On the other hand, the swivel bearing with a corresponding design of the housing or device parts without additional Component expense can be achieved by using it as a receptacle for the T-shaped extension piece provided angle piece with recess e.g. part of a housing or rack frame and the T-shaped extension piece receiving, for example, part of an electrical assembly or the like Are the carrier.

Weitere Einzelheiten der Erfindung werden an Hand der Figuren 1 bis 3 näher erläutert.Further details of the invention are based on FIGS. 1 to 3 explained in more detail.

In Fig. 1 ist das aus einem Winkelstück 1 und einem T-förmigen Ansatzstück 2 bestehende Schwenklager im zerlegten Zustand dargestellt. Gleichzeitig ist hier angedeutet, wie die beiden Teile in Eingriff gebracht werden.In Fig. 1 this consists of an elbow 1 and a T-shaped extension piece 2 existing swivel bearings shown in the disassembled state. At the same time is here indicated how the two parts are brought into engagement.

Die Fig. 2 und 3 zeigen die beiden Grenzlagen des Schwenkbereiches des an einem zu schwenkenden Teil angeordneten T-förmigen Ansatzstück es.FIGS. 2 and 3 show the two limit positions of the pivoting range of the T-shaped extension piece arranged on a part to be pivoted.

Das als Aufnahme ausgebildete Winkelstück 1 ist der feststehende Teil des Schwenklagers. Eine rechteckförmige Ausnehmung a erstreckt sich von einem Schenkel b des Winkelstückes bis über seine Biegekante e hinaus auf den Schenkel c. Die Biegekante e ist so gelegt, daß die Ausnehmung nur zu einem geringen Teil bis in den Schenkel c hineinragt. Der mit g bezeichnete Abstand der Biegekante e von der unteren Kante der Ausnehmung a im Schenkel c ist etwa gleich der Summe der Blechstärken von Winkelstück 1 und dem T-förmigen Ansatzstück 2.The angle piece 1 designed as a receptacle is the fixed part of the swivel bearing. A rectangular recess a extends from one leg b of the elbow up to its bending edge e out onto the leg c. The bending edge e is placed so that only a small part of the recess extends into the leg c protrudes. The distance, designated by g, of the bending edge e from the lower edge the recess a in the leg c is approximately equal to the sum of the sheet metal thicknesses of the angle piece 1 and the T-shaped extension piece 2.

Der schwenkbare Teil 2 des Schwenklagers mit dem T-förmigen Ansatzstück steht lösbar mit dem Winkelstück 1 in Eingriff. Der Schmalteil d des T-förmigen Ansatzstückes ist auf die Breitenabmessung f der Ausnehmung des Winkelstückes so abgestimmt, daß es mit einer der parallel zur Biegekante e verlaufenden Kante der Ausnehmung a die eigentliche Scharenkstelle bildet. Der gegenüber der Ausnehmung a breitere Querteil des T-förmigen Ansatzstückes liegt auf der Rückseite des Winkelstückes und kann die in den Fig. 2 und 3 dargestellten Endlagen einnehmen. In beiden Endlagen berührt der Querteil des T-förmigen Ansatzstückes formschlüssig jeweils einen der Schenkel b oder c. Wie in Fig. 3 gezeigt, können die beiden Teile 1 , 2 des Schwenklagers in den EndstJllungen miteinander durch eine Schraube fixiert werden.The pivotable part 2 of the pivot bearing with the T-shaped extension piece is releasably engaged with the elbow 1. The narrow part d of the T-shaped Extension piece is to the width dimension f of the recess of the angle piece so matched that it is with one of the parallel to the bending edge e running edge of Recess a forms the actual pivot point. The one opposite the recess a wider transverse part of the T-shaped extension piece lies on the back of the elbow and can assume the end positions shown in FIGS. In both end positions touches the transverse part of the T-shaped extension piece positively in each case one of the Leg b or c. As shown in Fig. 3, the two parts 1, 2 of the pivot bearing are fixed together in the end positions by a screw.

Der Wärmeübergang ist dabei optimal. Durch eine Drehbewegung kann das Teil 2 im nichtverschraubten Zustand in die andere Schwenklage (Fig. 2) gebracht und auch dort ggf. fixiert werden.The heat transfer is optimal. By turning it can brought the part 2 in the unscrewed state in the other pivot position (Fig. 2) and can also be fixed there if necessary.

Aus der Fig. 1 ist ersichtlich, daß die Abmessung der Ausnehmung a und die des Querteiles des T-förmigen Ansatzstückes so aufeinander abgestimmt sind, daß das Ansatzstück in diagonaler Lage zur Ausnehmung a mit dem Winkel stück in Eingriff gebracht werden kann.From Fig. 1 it can be seen that the dimension of the recess a and those of the transverse part of the T-shaped extension piece are matched to one another that the extension piece in a diagonal position to the recess a with the angle piece in Intervention can be brought about.
