Abstract

Cast (moulded) hinge for securing a door on a pin (8) which is retained in a receiving means of a cast member (1). In order to be able to produce such a cast hinge in a simple manner, it is provided that provision is made for two pairs of extensions (2, 3), between which the bolt (8) passes through an eyelet (9) of the door, and that the legs (11, 12) of the U-shaped clearances (4, 5) of the extensions (2, 3) converge towards the rounded web (6, 7), the two legs (11, 12) of a clearance (4, 5) enclosing an angle of approximately 10 DEG . <IMAGE>

Description

Die Erfindung bezieht sich auf ein Gußscharnier nach dem Oberbegriff des Patentanspruches.The invention relates to a cast hinge according to the preamble of the claim.

Bei einem aus der DE-PS 622 436 bekannten Scharnier ist die Aufnahme für den Bolzen durch U-förmige Ausnehmungen in Ansätzen sowohl des im wesentlichen festen Teiles als auch der Tür gebildet. Dabei ergeben sich jedoch bei durch Gießen hergestellten Teilen gewisse Schwierigkeiten, insbesondere hinsichtlich der Gießform.In a hinge known from DE-PS 622 436, the receptacle for the bolt is formed by U-shaped recesses in approaches of both the substantially fixed part and the door. However, there are certain difficulties with parts made by casting, particularly with regard to the mold.

Ziel der Erfindung ist es, die Nachteile zu vermeiden und ein Scharnier der eingangs erwähnten Art vorzuschlagen, dessen Teile sich auch im Gußverfahren einfach herstellen lassen.The aim of the invention is to avoid the disadvantages and to propose a hinge of the type mentioned at the beginning, the parts of which can also be easily produced using the casting process.

Erfindungsgemäß wird dies bei einem Gußscharnier der eingangs erwähnten Art durch die Merkmale des Kennzeichens des Patentanspruches erreicht.According to the invention this is achieved in a cast hinge of the type mentioned by the features of the characterizing part of the claim.

Durch die Anordnung von zwei Paaren von U-förmigen Ausnehmungen, deren Stege einander gegenüberliegen, wird eine sichere Aufnahme für den Bolzen geschaffen, wobei der die Aufnahme für den Bolzen tragende Teil sehr einfach in Spritzgußformen herstellbar ist.The arrangement of two pairs of U-shaped recesses, the webs of which lie opposite one another, creates a secure receptacle for the bolt, the receptacle for the bolt-carrying part is very easy to manufacture in injection molds.

Die Nichtparallelität der U-Schenkel erleichtert das Entformen des die Aufnahmen für den Bolzen tragenden Teiles nach dessen Herstellung durch Gießen.The non-parallelism of the U-legs facilitates the demolding of the part carrying the receptacles for the bolt after its production by casting.

Die Erfindung wird nun anhand der Zeichnung näher erläutert. Dabei zeigen:

  • Fig. 1 einen Teilschnitt durch ein erfindungsgemäßes Scharnier,
  • Fig. 2 eine Draufsicht auf das Scharnier nach der Fig. 1 und
  • Fig. 3 einen Schnitt entlang der Linie III-III in der Fig. 2.
The invention will now be explained in more detail with reference to the drawing. Show:
  • 1 shows a partial section through a hinge according to the invention,
  • Fig. 2 is a plan view of the hinge according to FIGS. 1 and
  • 3 shows a section along the line III-III in FIG. 2nd

Gleiche Bezugszeichen bedeuten in allen Figuren gleiche Einzelheiten.The same reference numerals mean the same details in all figures.

Das Scharnier nach den Fig. 1 bis 3 weist an einem Gußglied 1 angeformte Ansätze 2, 3 auf. Diese Ansätze 2, 3 sind im Bereich ihrer freien Enden mit U-förmigen Ausnehmungen 4, 5 versehen, wobei die die Ausnehmungen 4, 5 begrenzenden Stege 6, 7 eines jeden Paares einander gegenüberliegen.The hinge according to FIGS. 1 to 3 has projections 2, 3 molded onto a cast member 1. These lugs 2, 3 are provided in the region of their free ends with U-shaped recesses 4, 5, the webs 6, 7 of each pair delimiting the recesses 4, 5 lying opposite one another.

Dadurch verläuft der Steg 7 in der Draufsicht in Fig. 2 oberhalb und der Steg 6 unterhalb eines Bolzens 8, der eine an einem Gewindebolzen 10 angeformte Öse 9 durchsetzt. Dabei ist der Gewindebolzen 10 in eine nicht dargestellte, auch als Gußglied ausgebildete Türe eingeschraubt und verbindet diese mit dem Bolzen 8.As a result, in the plan view in FIG. 2, the web 7 runs above and the web 6 below a bolt 8 which passes through an eyelet 9 formed on a threaded bolt 10. It is the threaded bolt 10 is screwed into a door (not shown), which is also designed as a cast member, and connects it to the bolt 8.

Die Schenkel 11, 12 der Ausnehmungen 4, 5 konvergieren gegen deren Steg 6, 7 zu, um das Entformen des Gußgliedes 1 zu erleichtern, wobei zu dessen Herstellung aufgrund des Fehlens von vollständig von Wänden umschlossenen Bohrungen keine Formkerne erforderlich sind. Dabei schließen die Schenkel 11, 12 einen Winkel von ca. 10° ein.The legs 11, 12 of the recesses 4, 5 converge towards their web 6, 7 in order to facilitate the removal of the shape of the cast member 1, wherein no mold cores are required for its production due to the lack of holes completely enclosed by walls. The legs 11, 12 enclose an angle of approximately 10 °.
