Definitions

  • the invention relates to a corner connecting element for connecting each other approximately at right angles arranged profile elements, which have at least one miter, comprising two mutually in a connection angle connecting elements, which are introduced into at least one hollow chamber of the profile elements.
  • a corner connecting element for sealingly connecting two joined profiles, the ends of which lie against each other in an intermediate contact surface
  • the connection between these profiles is made by means of a corner connecting element which engages in both of these profiles
  • the corner connecting element comprises a soft element, and of protruding outwards so that it is compressed between the ends of the two mutually adjacent profiles in the contact surface
  • this soft element in this area ensures a discontinuity in Kapillarweg trapped between the two ends of the profiles of water, whereby the flow of water should be prevented by capillary action along this path.
  • the soft element can be rod-shaped and arranged in a recess, a groove or another opening of the corner connecting element.
  • the soft element is formed from a plastic foam.
  • a disadvantage of this corner connecting element is seen that the assembly cost, in particular of the soft element is high and that in particular the connection of the oppositely arranged at right angles profiles very complex and especially in the miter is not fully possible without gap formation.
  • Another disadvantage of this Eckrivsimplantations is that in production-related tolerances of the hollow chambers of the oppositely arranged profiles, for example the insertion is not possible or with so much play is possible that especially in the corner of the miter oppositely arranged profiles no exact preferably rectangular fixing this is possible without at least in the field of vision, an optically unsightly gap formation or step formation occurs.
  • This Eckmorselement for the frame corner joint for at least two hollow frame profiles has two or more connecting leg, said connecting legs engage in the mitered hollow frame profiles, wherein the connecting legs each have one or more spring leaves which abut as barbs against the inner surfaces of the hollow frame profiles.
