There are several versions of metal profile bars for window frames are known in which the Panes held by soft rubber profiles or with the help of additional clamping profiles on the frame be pressed. For this purpose, symmetrical metal profile bars, some of which are clad with plastic, are also available has been proposed. For the production of window frames from metal profile rods is the application of prefabricated corner connection parts known.

On the other hand, it has been proposed to increase the weather resistance of window frames, to manufacture these from plastic with a wooden core to improve the strength of the frame parts.

Most of these known designs of window frames using special profiles Although they do their job, because of the different profiles they are so expensive that they are suitable for the normal Housing construction are hardly economical.

This disadvantage is to be avoided by the frame designed according to the invention in which for the production of the inner movable frame as well as the outer fixed frame the same, serial manufactured profile bars and prefabricated corner connection parts are used, in which the core preferably made of multi-layer wood, structure-forming fibrous materials mixed with binders or Chips or foamed plastic or a combination of these materials. As a coat A plastic coating is applied around the core, if necessary with the interposition of a metal foil and / or an elastic insulating sleeve is used. For holding the pane or the filling or the sealing profiles Grooves are arranged symmetrically to one another on both sides of the profile bar.

According to the invention for the production of frame-shaped Components, in particular windows, doors, gates, wall panels, frames, furniture, etc. such Profile bar provided with symmetrically arranged grooves to accommodate the required Bracket, sealing or stop profiles after cutting both to fixed and to assembled movable frame.

This profile preferably consists of the core, the insulating sleeve and the outer skin and is in running Meter lengths prefabricated in the factory. The frame profiles are installed at the place of installation or use Cut to the required lengths and with or without the use of a connecting piece profile bar For the production of

Fig. 1 shows a section through a window frame, which consists of the fixed frame 1 and the movable frame 2, which according to the invention are both made of the same profile bar. The profile bar has a core 3 made of solid material, such as single or multi-layer sawn timber, the latter glued or glued together or made of structure-forming organic or inorganic fibers wetted with binders, wood chips or other vegetable raw materials suitable for structural formation. In addition, expandable plastics are suitable for the production of the core. The core can also consist of at least two parts 4, as shown in FIG. 1 on the movable frame 2, which are held at a distance on the circumference of the profile bar by inserted bodies 5. Tn the enclosed by these parts cavity 6 a hose made of plastic can be inserted, which with a z. B. by heat, steam, pressure physical or chemical means foamable plastic is filled. However, it is also possible to introduce the foamable plastic directly into the cavity. The insulating sleeve 7 made of cardboard or other material, including foam, optionally underlaid with a metal foil, serves as a cushion between the core 3 or 4, 5 and the outer skins. The connection between core 3 or 4, 5 and insulating sleeve 7 can be made, for example, by gluing or gluing. This covering can be arranged to absorb any stresses and changes in shape that may arise in the core 3 or 4, 5. This insulating cover can consist of wood fibers, natural fibers, chemical fibers or other suitable raw materials, which may be preformed, wetted with binding agents and prepolymerized, then placed on the core and further polymerized to a suitable degree of hardness using pressure and / or heat. Complete curing should preferably not take place. Insulating sleeves 7 made of cardboard or similar fiber structures, possibly impregnated with synthetic resin, can also be placed or glued onto the core, the contact surfaces being roughened in order to promote an intensive connection to the outer skin 8. The outer skin 8 serves as protection against the weather and consists, for example, of a material that is as dimensionally stable as possible, such as. B. glass fiber reinforced synthetic resin. The glass fibers can be sprayed together with the resin and the hardener on the insulating sleeve and then using z. B. pressure and / or heat, smoothed and cured. The outer skin 8 can also be produced in that glass fiber or other suitable fiber mats are impregnated with resin and prepolymerized. Then it is glued to the insulating sleeve 7, which encloses the core 3 or 4, 5, after which this outer skin using z. B. pressure and / or heat, if necessary, is hardened. This arrangement of the plastic insulating layer achieves very good weather resistance of the profile bar. The profile bar has longitudinal grooves 9 in a symmetrical arrangement, in which the uniformly formed beads 10 of the sealing profiles 11 and the mounting profiles 13 according to FIGS. 1 and 2 are received. The sealing profile 11 made of rubber or plastic can consist of a softer material at the contact tips. To hold a filling 12, for example a window pane, the holding profiles 13 according to FIGS. 1 and 2 have corresponding recesses 14. The tear filler 15 in FIGS. 1 and 2 can be pulled out of the longitudinal groove in a known manner, so that after the tongue 16 has been bent, the window pane or filling 12 can then be conveniently inserted or removed. In Fig. 3, a corner connection is shown, the z. B. receives the butt-cut legs 18 in a frame. The connecting corner 17 and the legs 18 are connected by dowels 19. In addition, the connecting corner 17, which consists of, for. B. plywood, pressed material or plastic can exist, as well as the frame 1, 2 recesses 20 through which a tensioning cable 21 is pulled. This tensioning cable 21 serves, if necessary, to increase the strength of the frame and can be retensioned by means of a simple device 22 which is embedded in the connecting corner 17 or in the leg 18. If necessary, the tension cable can also be accommodated in the interior of the beads 10. To form a frame, the legs 18 of which are mitred, a corner connecting part 23, as shown in FIG. B. glued and pressed veneers, plastic-wetted and pressed synthetic or natural fibers. In order to increase the tightness of the joint between the abutting leg ends and to support the permanent connection, a plastic film 24 is inserted. This plastic film can consist of, for. B. thermoplastic materials are made into the electrical resistance heating elements, such as wires or foils, are pressed. During the manufacture of the frames and the processing of the plastic films, the heating elements are connected to an electrical voltage. The heat generated by the river nut causes the film to flow and connects the ends of the legs with one another. In Fig. 5, a further frame connection of two colliding legs 18 is shown. The angled corner connection part 25 consists of a core 26 which is made of electrically conductive material with high resistance. This core 26 is made of glass fiber reinforced plastic, e.g. B. polyester resin, coated. At the point of intersection of the legs of this corner connection part 25, the same is preferably expanded in an elliptical shape. When the diagonally cut frame legs 18 are pressed together, this elliptical extension is inserted into the milled, uniform recess 27 at the ends of the frame legs. The ends of the core 26, designed as an electrical resistance heating element, in the corner connection part are connected to an electrical voltage and thus the core is heated. The heat is transferred to the casing of the corner connector c25 and the synthetic resin contained in the casing, for example, begins to flow. When it hardens, a firm, permanent connection is created between the corner connection part 25 and the frame legs 18. The connection of the core 26 to the power supply line is achieved by drilling holes 29 from the surface at the end of the bore 28 to accommodate the corner connection part 25 into which the connector is inserted. Later these holes 29 are filled with synthetic resin. PATENT CLAIMS: 1.
