Definitions
- the invention relates to a method for producing plastic spacer frames for insulating panes or insulating glass systems as well as the plastic spacer frames produced by the process self.
- Metal hollow profiles have traditionally been used as spacers and as continuous material on bending machines to the spacer frames processed.
- German patent applications DE 198 05 348 A1 and DE 198 07 454 A1 describes plastic spacers, in which metal reinforcement elements over the length of the hollow plastic profiles are embedded, which when bending the elastic Push back the spring-back effect of the plastic material should.
- the object of the present invention is to provide a method with the plastic spacer for insulating washers on conventional bending systems (for the production of spacer frames made of metal) can, without having to accept the aforementioned problems are.
- the plastic hollow profile can be bent in one intended area and then with a Stiffening element are provided.
- the reinforcing elements executed as metal parts and more preferably have these Metal parts in the area of the bend a taper or constriction on.
- Metal parts are particularly suitable as stiffening elements because they are easy to deform and the deformation is permanent. This allows you to reliably use the elastic Counteract the spring back effect of the plastic material. Becomes the stiffening element as a metal part in the area of the bend trained with a taper, so is already on the part of Stiffening element the bending point on the plastic hollow profile predefined and also makes it easier to use less material in the bending area on the part of the stiffening element Deformation of the hollow plastic profile because of its plastic material there is additional space for evasion during the bending process.
- stiffening element lies in this in the cavity of the plastic profile on the Place where the plastic hollow profile is bent shall be. As a result, the stiffening element in the hollow plastic profile hidden and does not optically fall at all Weight.
- the stiffening element can also be attached to the outer Surfaces of the plastic hollow profile are arranged, which later becomes invisible with the composite insulating glass pane stay d. H. for the side walls and the frame seen from the outer surface. This leaves one special easy manufacturing too.
- the stiffening element on the side walls or on the outside of the finished frame Surface of the plastic hollow profile is to be arranged, Recesses in the hollow plastic profile for inserting the stiffening elements intended.
- these recesses can provided over the entire length of the hollow plastic profile be and trained with the extrusion of the profile be or in the plastic hollow profile in the areas of the bends are molded. When molding are preferred machining steps used.

- angles Flat materials for example being provided here can that the flat materials at the point to be turned have a triangular or V-shaped recess, the both legs of this V-shaped recess in the bent state come to rest against each other and for example with a The welding point can be connected to one another and thus fixed. This brings the stiffening element or the so produced Plastic spacer frame additional stability.
- Metallic stiffening elements are preferred in the curved Shape fixed by welding, gluing or upsetting.
- pouring, melting or Gluing the stiffening elements can be made to this in addition to fix and, if necessary, an additional reduction the elastic springback effect of the hollow plastic profile to effect.
- the present invention relates to plastic spacer frames for insulating panes or insulating glass system from a plastic hollow profile with one or more angled areas or corners, with the frame in the Corner areas each comprises a stiffening element arranged.
- preferred stiffening elements are metal parts, especially in the form of hollow profiles, in the form of Flat material (solid material) or round profiles.
- the stiffening elements are inside of the plastic hollow profile and are so the eye in essentially hidden.
- stiffening elements outside on the surfaces of the hollow plastic profile are arranged.
- Such surfaces are preferred selected that later in the finished insulating glass system or remain hidden from the insulating washers. These are in particular the side surfaces of the hollow plastic profiles or also those that are external to the finished frame Surfaces.
- the stiffening elements are not inside the plastic hollow profile arranged, then it is advisable to the charged Provide surface recesses, these of can be extruded into the plastic hollow profile beforehand or can be molded into the corner area afterwards.
