  • Such a hinge connection also enables a symmetrical structure of the folding or pivoting share, which can be described as elegant.
  • the known hinge connections always consist of several parts, the semi-cylindrical body rolling on each other being designed as a load-bearing, rigid profile element for receiving the surface element to be connected thereto.
  • the hinge straps or cross straps connecting the half-cylinder bodies are made of flexible material and are fastened to the half-cylinder bodies at diametrically opposite ends in each case.
  • the attachment can be designed in the form of a positive locking connection (GB 21 89 290) or in the form of positive, U-shaped overlaps (DE 36 39 668).
  • the method according to the invention provides for the production of a hinge connection for the articulated connection of surface elements, the structure of which is considerably simplified.
  • the two half-cylinder bodies, including the hinge band connecting them are produced simultaneously and in one piece in an extrusion process.
  • the two half-cylinder bodies are shaped simultaneously by means of a main extruder and corresponding outlet nozzles, while the hinge strap is simultaneously required by a secondary extruder.
  • the half-cylinder body can be made from a hard plastic, and the hinge band from a flexible, soft plastic.
  • the method according to the invention therefore represents a very economical and therefore inexpensive way of producing a corresponding hinge connection the two half-cylinder bodies including the hinge connecting them are made in any length and cut to length depending on the application.

  • the hinge tapes 6, 6 ' are each integrally connected to them at the outermost end 15, 15' of the semicylindrical bodies 4, 5 and 4 ', 5' which are semicircular in cross section. As can be seen from Fig. 3, this is done by a one-piece plastic profile, which can be produced as an extruded plastic profile in the extrusion process.

  • An additional auxiliary extruder ie an extruder for producing the "soft" hinge portion, is provided as a further “co-extruder”. Press both co-extruders together their plastic in a nozzle via different channels in different outlet sections or outlet nozzle sections. The merging takes place at the separating sections of the hard and soft plastic material shortly before the final exit from the nozzle.
  • the profile is produced as an endless profile.
  • Hinge connections 4, 5 and 4 ', 5', which are to be arranged in mirror image, are formed by deflecting and rotating the profile by 180 °.

Abstract

On propose un procédé pour la fabrication d'un assemblage à charnière pour l'assemblage articulé de deux éléments de surface, tels que deux panneaux et similaire, composé d'au moins deux charnières individuelles (1, 1'). Chaque charnière (1, 1') est composée de deux corps semi-cylindriques (4, 5) roulant l'un sur l'autre par leurs enveloppes de cylindre et étant assemblés entre eux au moyen d'un ruban de charnière en S. La deuxième charnière présente une rotation de 180° par rapport à son axe longitudinal, de manière à ce qu'il en résulte une charnière en croix. Afin d'assurer une fabrication aussi simple et rationnelle que possible, les deux corps semi-cylindriques (4, 5) sont fabriqués, en même temps que le ruban de charnière (6) qui les relie, en une seule opération et d'une seule pièce sous forme de profilé en aluminium.
