Profile and method for producing a profile

Abstract

The invention relates to a profile ( 1 ) for the frames of wall elements, doors or windows, comprising a top part ( 16 ), a bottom part ( 2 ) and side walls ( 3, 4 ) interlinking the same. Said side walls ( 3, 4 ) have webs extending at an angle and considerably reducing heat transfer due to thermal conduction. The side walls ( 3, 4 ) are configured in such a manner that the height (h) of the side walls is smaller or equal the distance (A) between the front walls of the top part ( 16 ) and the bottom part ( 2 ). The side walls ( 3, 4 ) are furthermore welded to the top part ( 16 ) and/or the bottom part ( 2 ).

       28 . The profile as claimed in  claim 25 , wherein at least one side wall has respectively laterally disposed, preferably U-shaped mounting for the reception of a side element.  
   
   
       29 . The profile as claimed in  claim 25 , wherein the side walls have parallel-running guide grooves.  
   
   
       30 . The profile as claimed in  claim 25 , wherein the webs are configured as a row of approximately V-shaped arrangements.  
   
   
       31 . The profile as claimed in  claim 25 , wherein a lining is attached to the side walls.  
   
   
       32 . The profile as claimed in  claim 25 , wherein the chamber formed by the side walls, the top part and the bottom part at least partially contains insulation material.  
   
   
       33 . The profile as claimed in  claim 25 , wherein the top part and the bottom part respectively have angular deviations, on which there are disposed inwardly directed end faces provided with a stop for a side wall.  
   
   
       34 . The profile as claimed in  claim 33 , wherein the angle formed by an angular deviation or a stop and an end face, is between 5° and 135°.  
   
   
       35 . The profile as claimed in  claim 34 , wherein said angle is between 20° and 90°.  
   
   
       36 . The profile as claimed in  claim 34 , wherein said angle is about 90°.  
   
   
       37 . The profile as claimed in  claim 33 , wherein the inwardly directed end faces and the stop form a groove for the reception of side walls and preferably of side elements.  
   
   
       38 . The profile as claimed in  claim 33 , wherein the side walls are welded to the end faces.  
   
   
       39 . The profile as claimed in  claim 33 , wherein the side walls are welded to the stops.  
   
   
       40 . The profile as claimed in  claim 25 , wherein the top part and bottom part are made of steel and the side walls of a material having lower thermal conductivity than steel, especially of high-grade steel.  
   
   
       41 . The profile as claimed in  claim 25 , wherein at least one of said webs has a bead running in the longitudinal direction of the web.  
   
   
       42 . A profile for frames of wall elements, doors or windows, having a top part and a bottom part and side walls which connect the same and having openings, wherein on the side walls, in the region of the openings, there are inwardly deformable cams for the fixing of insulation material.  
   
   
       43 . The profile as claimed in  claim 42 , wherein the insulation material is held by the cams in a non-positive and/or positive manner.  
   
   
       44 . The profile as claimed in  claim 42 , wherein a cam is disposed approximately centrally in the region of the base of an opening.  
   
   
       45 . The profile as claimed in  claim 42 , wherein the insulation material is disposed in the region of the side walls, an upper and lower chamber being formed.  
   
   
       46 . A method for producing a profile for frames of wall elements, doors or windows, having a top part, a bottom part and side walls which connect the same, insulation material being provided between the side walls, said method comprising a step of deforming the side walls to fix the insulation material in the profile.  
   
   
       47 . The method as claimed in  claim 46  for producing a profile, wherein said side walls additionally have webs, and inwardly deformable cams are provided for the fixing of insulation material, wherein the cams are pressed in inward during the deforming step.  
   
   
       48 . The method for producing a profile as claimed in  claim 47 , wherein the cams are pressed into the insulation material or, through plastic deformation of the insulation material, engage positively in the latter.  
   
   
       49 . A method for producing a profile for frames of wall elements, door or windows, having a top part, a bottom part and side walls which connect the same, the side walls having webs, said method comprising steps of forming openings in the side walls for the formation of the webs, and subsequently welding the side walls to the top part and the bottom part.  
   
   
       50 . A profile produced by the method of  claim 46.
