Abstract

A composite wooden profile (1) for the manufacture of window and door wings (2) and frames (3) is proposed, consisting of at least three strips of wood (11, 12, 13), joined with one another and glued together along the whole length, namely of the end strips (11, 13) and of at least one central strip (12) arranged between the latter two, where at least the said centrally arranged strip (12) is fitted with a lengthwise, basically uninterrupted groove (120) which is filled with an appropriate thermal insulation core (125). On both sides of the strip (12), the said groove (120) is ending at a certain distance from the ending areas (121, 122), which are foreseen for mutual joining of the profile (1) with the respective profile (1) in corner areas (21, 31) of the thus obtained window or door wing (2) or frame (3). The window or door wings (2) and/or frames (3) consisting of this kind of profiles (1) excel in their enhanced thermal insulation properties, and at the same time, in high stiffness, particularly in the corner areas (21, 31).

Composite wooden profile for the manufacture of window and door sash and frames and windows and doors, comprising a sash or frame consisting of such profiles

The invention belongs to the field of construction, namely to the field of wooden window and door frames, which consist of several wooden parts and combined with other materials.

The invention is based on the problem of how to design a solid-wood profile, which is to be distinguished by the significantly improved thermal insulation properties required for installation in so-called solid wood. energy-passive buildings, whereby these thermal insulation properties can be varied and adjusted to the same width of the window or door leaf or frame, which can nevertheless be manufactured quickly and easily, while improving the thermal insulation properties retained entirely of solid wood consisting of a single window or door frame, adequate rigidity of such frame.

Window with commercial name "Passivhausfenster" by VARIOTEC Sandwich-Elemente GmbH & Co. KG KG, Neumarkt (DE) is presented, inter alia, at www.fenstertechnik-weinfurtner.de. The profile for the manufacture of the sash and frame of this type of window consists of three sandwiches, stacked and glued together, each one of them, consisting of solid wood. The thickness of the strips may in principle be the same or at least approximately the same. The width of the centrally spaced lath is significantly smaller than the width of the end moldings, so that in such a glued profile of solid wood laths, a centrally spaced groove is then available, which is then filled with thermal insulation material, e.g. with polyurethane foam. Due to the presence of an additional thermal insulation filler in the said groove, this profile and also the window or door sash or frame consisting of such profiles are distinguished by their improved thermal insulation capabilities. However, the window strength is considerably weakened, which is mainly reflected in the reduction of stiffness, which is especially pronounced for windows of medium and large spans. Since the width of the moldings of the profile is unchanged over the entire length of the profile, it is necessary to account for the significant attenuation from the profiles of the standing wing and frame in the corner areas. Particularly for larger windows, the bending stiffness of this profile is also expressed, which means that windows have to be over-dimensioned and stronger profiles must be selected for this purpose, which, due to higher material consumption, is reflected in higher production costs, and, moreover, light permeable window surface. In addition, the thermal insulation capability of this type of frame depends on the chosen thermal insulation material and on the width and / or width. thickness of thermal insulation layer. Whenever there is a demand for greater insulation of a frame, the insulation of the latter can therefore be modified only by increasing the thickness of the entire frame, using affordable thermal insulation materials, which, in addition to other negative effects, significantly appreciates the overall frame.

Furthermore, windows and doors known from DE 20 2008 013 830 Ul, which, similar to the windows described above, are made of profiles, each consisting of sandwich-stacked and glued solid wood laths, all along the entire length. Each of said laths is provided with a series of parallel grooves and relatively deep grooves extending along its entire length in the area of its surface which is intended to fit on each adjacent lath in the composite profile. In this way, after assembling and gluing said laths, the profiles obtained in each case are spaced apart from each other and closed cavities running along the profile inside which there is still air, which is a thermal insulation agent, thanks to which the thermal insulation properties of the profile are thereby obtained. the entire window or door frame improved accordingly. This kind of profile is still relatively tricky in terms of manufacturing itself, but it certainly has to take into account significantly more time and tools than in the case described above. In this case, too, at least in some embodiments, the grooves extend along the entire length of the laths. Therefore, the frame or sash of the window or door frame obtained in the corner areas in which the profiles are interconnected must be significantly weakened, which is reflected in the reduced rigidity of the sash or frame thus obtained. Strength or. The stiffness of the frame can, in principle, be improved by moving the start of the grooves out of the end or. corner areas and then the corner areas of the composite frame profiles are available in solid wood without grooves. However, even in this case, the degree of insulation depends on the number and arrangement of the grooves, that is, on the volume in the grooves of trapped still air. The need to increase the insulation of the frame can therefore either lead to an increase in the volume of the grooves and thus to a more intensive grooving and weakening of the rigidity of the frame, or to an increase in the width and thus the profile price.

As can be seen in FIG. 1, the profile 1 for the manufacture of window or door leaf 2 or frame 3, as the case may be, consists of three interconnecting lengthwise and rigidly interconnected, in particular glued laths 11, 12, 13, wherein the central lath 12 is provided with either a substantially continuous or at least once interrupted suture 120, which, on either side of the sash 12, is terminated at a distance from the end zones 121, 122 intended to interconnect the profiles 1 in the corner areas of the sash 2 thus obtained, respectively. frame 3. Said paras 120, which is therefore made in the centrally arranged lath 12 only in the central area 123, i.e. outside the end zones 121, 122, it is filled with a suitable thermal insulation fill 125.

According to the invention, it is further provided that at least one insert 126, which may consist of wood or another, e.g. thermal insulation material, and which e.g. by bonding rigidly to said laths 11, 12, 13 of profile 1. Preferably, at least two inserts 126 are provided in the joint 120, arranged at a suitable spacing and at the same distance from the two end regions 121 , 122 laths 12. The space available in the groove 120 at each of the inserts mentioned 126 •

in any case, it is filled with a thermal insulation fill 125. The presence of said inserts 126 further helps to improve the rigidity of the moldings 11, 12, 13 of the composite profile 1 and also of the profiles 1 of the composite window or door leaf 2 or frame 3.

As can be seen in FIG. 1 in conjunction with FIG. 4 to 6, in the first embodiment of profile 1 for making window or door leaf 2 or frame 3, said joint 120 is provided as a groove. In this case, after assembling and gluing the laths 11, 12, 13, the thermal insulation fill 125 is surrounded by the material of the laths 11, 12, 13, ie solid wood, over the entire contour of the window or door leaf 2 or profile 3, therefore the thermal insulation fill 125 outwardly invisible. In this case, filler 125 and inserts 126 must also be inserted. insert into the joint 120 before assembling the laths 11, 12, 13 or. forming a composite profile 1.

On the other hand, in the further implementation of profile 1 according to FIG. 10 in conjunction with the relevant views of FIG. 11 - 16 for the manufacture of window or door leaf 2 or frame 3 according to FIG. 7 - 12, the said parasol 120 is made solely as a stepped recess or. narrowing the lath 12 in its central region 123 beyond the corner areas 121, 122, so the insulating fill 125 extends to the circumference of profile 1 and is in principle visible from the outside, although it can then be optionally covered with a layer of other material. In this case, filler 125 is possible and optionally even inserts 126 into the area of said bucket 120 even after assembly of the laths 11, 12, 13 and. forming the profile itself 1.

As can be seen in FIG. 4 - 9 and 11 - 17, respectively, obtained from solid wood laths 11, 12, 13 and with thermal insulation fill 125, available in the joint 120 in the central lath 12 at a distance from the end zones 121, 122, consisting profile 1 as a semi-finished product, useful for further processing into the respective profile of the concrete window or door leaf 2 (Figs. 4 - 9 and 11-16) or frame 3 (Fig. 17), which are adapted to each other in terms of corresponding functionality. However, according to the invention, the window or door leaf 2 or frame 3 in each case consists of profiles 1 which, in the area of the central lath 12 only outside its end regions 121, 122 and therefore outside the corner areas 21, 31, comprise a thermal insulation fill 125, said corner areas 21, 31 of the window or door sash 2 or frame 3 retained baseline strength of solid wood laths 11, 12, 13, which then provides rigidity and rigidity to the window or door sash 2 or frame 3. To further improve the stiffness of the window or door leaf 2 or frame 3, the presence of at least one insert 126, which is inserted at a distance from the corner areas 21,31 into the available receptacle 125 and is rigidly connected to said slats 11, 12, 13 of profile 1. Preferably, at least two inserts 126 are provided in the joint 120 of each of the profiles 1, which consists of a window or door sash 2 or a window or door frame 3, respectively, arranged at an appropriate spacing and at the same time at the corresponding offset from both end zones 121, 122 of lath 12.

As further illustrated in the accompanying drawing (Figs. 10-17), the profile 1 of each window sash 2 or frame 3 can also be designed in such a way that, in addition to the central lath 12, at least one of the end laths 11, 13 can be fitted with the joint 130. In this case, too, in a completely analogous manner to the cases described above, and in a manner understandable to the person skilled in the art, each bundle 130 is filled with a filler 135 of thermal insulation material, and optionally in combination with suitable inserts of wood or other, e.g. thermal insulation material, each insert being rigidly connected to the corresponding lath 11, 13 in which a lug 130 is provided.

Thanks to the design described, this profile is distinguished by the fact that, despite its predetermined width or width, the rigidity of the profiles of the composite window or door frame or wing is retained due to the retention of intact and solid timber corners. different thermal insulation properties can be provided to the thickness of the profile.
