  • the invention relates to a frame made of such profile elements for a window or a door, especially a sash, and a wing for a window or a door, which has at least one included in the casement glazing element except said wing frame.
  • the invention relates to a method for stiffening a profile element and - building on it - a (wing) frame or a wing for a window or a door.
  • main profile or "main profile element” as used above includes in the context of the invention in particular frame and sash profiles as well as forend and post profiles.
  • additional profile or “additional profile element”, e.g. Profiles for widening and static coupling understood.
  • the term “stiffening material” as used above comprises in particular materials which have a higher rigidity than the plastic material of the profile element to be stiffened. This includes, for example, metal (preferably aluminum) as well as glass fiber reinforced plastic (GRP) or wood.
  • attachment shells which are usually made of aluminum, can be applied to the outside of a window or a door. In general, this is done by positive connection, in particular by clipping. In addition, it is known to secure the attachment shells punctually by gluing.
  • window or door elements with a colored, so not white (decor) surface can not be built without additional reinforcements.
  • a steel reinforcement in particular has an unfavorable effect on the thermal properties of the window or door element.
  • the invention has for its object to produce profile elements in particular for the production of frames for window or door elements with a relatively large size and / or colored surface, despite a waiver of Stahlarmtechnik or with significant reduction of a required dimensioning the stiffening are not subject to restrictions on the functionality of climatic loads.
  • the object is achieved by a profile element with the features of claim 1, by a frame with the features of claim 8, by a wing with the features of claim 9 and by a method having the features of claim 10.

Through the proposed functional bonding, the static properties of the facing shell for stiffening the wing or sash can now be used in total, so that the latter - even without steel reinforcement - can be built much larger, without restricting the functionality of the window or the door at climatic loads.
