Definitions

• The, present invention has thus for its purpose to provide a window element which is not subjected to the traditional disadvantages of window elements and additionally can be prepared to competitive prices.
• the window element for the use of the window element as a window frame it has in cross-section mainly rectangular shape and the outer part of the inner face is somewhat bevelled to facilitate water drainage.
• the window element in this embodiment is built up from at least two profile elements, one of which having largely U-shape with edge flanges bent inwardly over more than 90°.
• the other profile element has largely U-shape except the part forming the bevel, and also this profile element is provided with edge flanges bent inwardly over more than 90 and facing the edge flanges of the first-mentioned profile element.
• the two profileelements are kept together by means of foam plastic arranged in the space formed by the profile elements.
• the edge flanges are at some distance from each other to avoid formation of thermal bridges.
• a rubber or plastic ledge In the gap between the edge flanges there may be arranged, if desired, a rubber or plastic ledge.
• the plastics material arranged between the profile elements is suitably constituted by a hard foam plastic, and here it is preferred that the material is foamed up in situ between the profile elements in conjunction with producing the window element.
• the material in the profiles incorporated in the window element is preferably sheet metal, for example sheet steel, galvanized sheet steel, aluminium sheet metal or the like.
• the profile elements 3iay also be made from some other material, for example hard plastic.
• the thickness may vary from some tenths of millimeter up to around 1 mm. A preferred thickness is, however, within the range of about 0.25 to 0.75 mm, particularly about 0.4 to 0.6mm.
• Fig. 1 there is shown in perspective part of a window frame designed in accordance with the invention.
• This window frame generally designated 1 has an essentially rectangular cross-section except for an outwardly facing bevelled part ⁇ intended to facilitate drainage of water.
• the window frame 1 is built up from three profile elements 3, 5, 7.
• the inwardly facing profile element 3 has U-shape and is provided with longitudinally extending inwardly bent edge flanges 9a,
• Window frame 1 further includes a second profile element 5, one part 6 of which forms bevel of window frame 1. Also this profile element 5 is provided with longitudinally extended inwardly bent edge flanges 11a, lib.
• the window frame 1 includes a third profile element 7. which is right-angled and is provided with longitudinally extending inwardly bent edge flanges 13a, 13b.
• the three profile elements 3, 5, 7 are assembled together by means of a foam plastic 15 in a manner shown in Fig. 1.
• there is a gap 16 between edge flanges 11b, 13a the function of which is to enable arrangement of a window sheet not shown in Fig. 1 which can be either inserted afterwards in gap 16 or can be moulded in situ in connection with the manufacture of the window frame 1.
• Window frame 1 of which only a part is shown in Fig. 1 Is in other respects designed in the traditional manner, i.e. in the form of a rectangular round-going frame with a bevel 6 facing outwardly.
• the joining of the part elements of the frame can be made in a wholly conventional manner, either by joining the corners with 45° chamfer or while using right-angled joints.
• the assembly can be made by gluing and/or screwing or any other traditional manner.
• Fig. 2 shows the building element according to the invention designed as a window sash.
• the window sash, generally designated 18, has a general T-shaped cross-section.
• the window sash includes two profile elements 20, 22, one 20 of which has twice over 90o bent edge sections 21a, 21b provided with longitudinally extending inwardly bent edge flanges 24a and 24b, respectively, the bending angle of the embodiment shown being largely the same as that shown in Fig. 1.
• the second profile element 22 has a U-shaped cross-section and is provided with longitudinally extending edge flanges 26a, 26b bent Inwardly In the same manner.
• the profile elements 20, 22 put together according to Fig. 2 are kept together by foam plastic 13 foamed in situ in the space between same.
• the profile elements 20, 22 are assembled under the formation of a gap 28 between the longitudinally extending edge flanges, thereby avoiding the drawback of the formation of a thermal bridge between the inwardly facing part of the window sash and its outwardly facing part.
• a rubber or plastic ledge can be moulded in situ for example for sealing purposes.
• the window element according to the invention can be produced at a comparatively low price and be made with any cross-section and any length. Furthermore, in using the window element the formation of thermal bridges is avoided as. a rule, the cohering foam plastic serving as an insulation. Moreover, the window element according to the invention, gives a very good strength. It should be noted that the .Invention is not limited to the embodiments shown above but can be modified in several respects within the scope of the invention. Thus, the bent edge flanges can be formed in a multitude of ways as long as they are bent at least about 90 for anchoring in the plastic material. Moreover, they can have double bends "to provide even better anchorage. Furthermore, the cross-sectional form of the window element can be varied arbitrarily.
