Definitions

• the present invention belongs to the field of building construction, namely to wooden door or window frames, which are assembled of several wooden parts and combined with other materials.
• the purpose of the invention is to create a profile, which should consist of massive wood and should moreover excel in essentially improved thermal insulating properties, which are required in building-up energetic passive buildings, wherein also a possibility of varying or adjusting said thermal insulating properties is desired regardless to unchanged width or thickness of door or window wing or frame, and which should be regardless to that quickly and easily manufactured, wherein at the same time despite to such improved thermal insulating properties the overall rigidity should be maintained at such level, which normally corresponds to the level of a door or window frame, which consists solely of massive wood.
• a window which is known under a commercial name »Passivhaus pre « and is manufactured by VARIOTEC Sandwich-Elemente GmbH & Co.
• a profile, which is foreseen for manufacturing a wing and a frame of such window consists of three massive wooden ledges, which are longitudinally assembled and sealed a sandwich-like manner. Ledges may generally have the same or at least approximately the same thickness.
• the width of the intermediate ledge is essentially smaller than the width of lateral ledges, so that a centrally located groove is available in such massive wooden profile, which is then filled with a thermal insulating material, for example with polyurethane foam.
• said profile and also a wing or a frame made of such profiles then excels in improved thermal insulating properties.
• window is essentially weakened regarding the rigidity, which is particularly apparent in medium or large windows with respect to overall dimensions thereof.
• the ledges, which form such profile have a constant width along the completely length, and each wing or frame is correspondingly weak in its corner areas.
• windows having large overall dimensions suffer on bending stiffness of such profiles, so that the width of profiles must be adequately increased, which involves essentially higher consumption of materials and correspondingly higher costs, by which however also effective light permeable surface is correspondingly reduced.
• each thermal insulating capability of such window depends on each used thermal insulating material in combination with each disposable width or thickness such insulation layer, respectively. As soon as some higher insulating efficiency is required in a window frame, then by using an economic acceptable material such thermal insulating efficiency can be increased exclusively by increasing of thickness of the whole frame, which in addition to other deficiencies leads to essential increasing of the price of such frame.
• doors and windows are disclosed in DE 20 2008 013 830 Ul, which are analogously as the previously described ones made of profiles, which consist of sandwich-like assembled massive wooden ledges, which are sealed along the complete length thereof.
• Each ledge is furnished with a plurality of relatively deep grooves, which are arranged on the side faced towards each neighboring ledges and extend parallel with respect to each other and extend along the complete length of the ledge. Consequently, after assembling said ledges in order to obtain each desired profile a plurality of cavities is obtained, in which the static air is contained, which forms a thermal insulating means for correspondingly improving thermal insulating property of such profile and consequently also of a complete door or window frame.
• said grooves extend along the complete length of the ledges or profile, so that such profile is weak in its corner areas where the profiles are interconnected, and the rigidity of the frame or the wing obtained in such a manner is then correspondingly reduced.
• Said rigidity or stiffness of such frame may generally be increased by ending said grooves at certain distance apart from each corner area.
• the thermal insulating capability depends on the number and arrangement of said grooves, and consequently of the volume of the air, which is available therein.
• the present invention refers to a composed wooden profile for manufacturing of door or window wings and frames, such profile comprising at least three longitudinally assembled and mutually sealed ledges, namely lateral ledges and at least one intermediate ledge arranged there-between, wherein said intermediate ledge comprises a longitudinal recess, which is filled with appropriate thermal insulating filler.
• said recess is ended on both sides of said ledge at certain distance apart from both end portions of the intermediate ledge, where appropriate interconnection of each profile with each neighboring profile is established in order to obtain each desired door or window wing and frame.
• Said recess in the intermediate ledge is either continuous in its longitudinal direction, or may also be at least once interrupted in its longitudinal direction and may consist of at least two linearly aligned sections. .At least one insert is inserted within said recess of the intermediate ledge in addition to said filler, and is firmly interconnected with the belonging ledge.
• At least two inserts are foreseen within said recess, which are arranged at certain distance apart from each other and also apart from both end portions of the ledge.
• Each insert may consist of wood or any other sufficiently strong material, optionally of the same material as the thermal insulating filler.
• Each of disposable inserts is firmly interconnected with the intermediate ledge by means of adhesive.
• Said ledges are mutually interconnected by means of adhesive, while said filler preferably consists of polyurethane foam.
• Said recess may either be a groove, which extends in the longitudinal direction of the intermediate ledge and is ended apart from both end portions thereof, or may also be a step-like depression or contraction, which extends along the complete length of the ledge except of both end portions thereof.
• At least one lateral ledge is furnished with a longitudinal recess, which is filled with thermal insulating filler.
• said recess may either be continuous in its longitudinal direction, or may also be at least once interrupted in its longitudinal direction in order to consist of at least two linearly aligned sections.
• at least one insert is inserted within said recess of the intermediate ledge in at least one lateral ledge in addition to said filler, and is firmly interconnected with each belonging ledge. It may also be preferred, if at least two inserts are foreseen within said recess, which are arranged at certain distance apart from each other and also apart from both end portions of the ledge.
• Each of disposable inserts is firmly interconnected with each belonging lateral- ledge by means of adhesive.
• said ledges are mutually interconnected by means of adhesive and said filler preferably consists of polyurethane foam.
