Definitions
- the invention relates to windows as they are provided in buildings for the purpose of incidence of light and the possibility of opening (ventilation and escape routes).
- Such windows consist of a frame-shaped window frame fixed in the masonry as well as a window sash, which is mounted in it via hinges or other fitting parts and therefore movable, which in turn surrounds the transparent pane accommodated therein in a frame shape.
- the opaque parts i.e. the window sash or the window frame, are made of wood and are connected to each other by metal fittings.
- windows have increasingly established themselves, the sashes or sticks of which are usually hollow, plastic profiles, mostly consisting of PVC, or metal profiles, mostly consisting of aluminum.
- the frame-shaped wings or sticks are always composed of deflected, usually mitred, profiles, which are mitred via connecting elements connected or simply glued together. Even with the traditional method of manufacturing from wood, the stick and sash are created from individual profiles and fixed to one another by interlocking (mortising) and gluing.
- the pane In windows made of wood, the pane is fixed by means of so-called glass retaining strips, in that - viewed in cross-section - the pane - today mostly an at least two-layer glass pane with a sealed gas or air volume in between - from one side, usually the inside, inserted in a corresponding rebate of the finished window sash and the glass retaining strips were attached from the other side and fixed, mostly nailed, radially outwards relative to the window sash.
- the individual glass retaining strips are mitred in the corners and adjoin each other.
- panes are either fixed by means of analog glass retaining strips, which only consist of the appropriate material (plastic or aluminum), or rubber profiles that accommodate the pane, which are dimensioned sufficiently strong and have a sufficiently high rigidity to hold the relatively heavy insulating glass pane in the To hold wings.
- the painting in the desired color of the user is usually made of a material that does not correspond to the base material used for the window sash or window frame, so that the painting is done solely by the opaque window parts a material mix is created, which makes recycling the window difficult, if not impossible.
- the now legally required thermal insulation values of a window can hardly be achieved, or only with cross sections of the window sash and window frame, which are very large and thus - in addition to the necessary stability of the window - on the one hand the manufacturing costs due to the higher Increase the need for material unnecessarily and, from a visual point of view, result in window frames that are too wide compared to the window panes.
- the window frame and / or the window sash - apart from the retrofitted pane - is each made as a one-piece, seamless frame part, possibly with additional rungs, weatherstrips, etc. sitting on the glass, only need for final assembly two such frame parts are fixed against each other, which is usually by means of locking, or not detachable at all by means of surface gluing.
- the panes are also held in a form-fitting manner between the two sash frames. If the window frame has a kind of window frame including soffit and window sill, which sits on the front of the wall, this frame can also be integrally formed on the outer frame or there is only a single one-piece frame with molded frame.
- the disadvantage of the possibly lacking flexibility in the dimensions is offset by a standardized grid of the lengths and widths of the windows and by a shape that is preferably variable in terms of length and width of the window by interposing several extensions or. Widening fittings, which can also contain fighters, additional rungs and the like.
- Such a window is particularly inexpensive to manufacture if the frame-shaped parts of the cane and sashes are cast or injection molded from plastic and in particular from solid plastic and not from hollow material, and in particular the same material with the same physical parameters throughout the entire cross-section, with regard to density and thermal conductivity is used.
- the production takes place by entering two components in a z. B. closed on all sides chemical reaction of the two components with volume increase and thereby pressure in the mold occurs.
- the end product can have a higher density at the edge of the cross section, in particular approximately 20% higher density than in the central region.
- Polyurethane is preferably used, since this offers the additional advantage that the adhesives then required for gluing such parts as well as paints for painting the parts are based on the same basic material, namely polyurethane, and thus lacquered or glued parts do not have a material mix but represent a uniform material.
- Windows of this type are therefore easily recyclable due to the fact that only metal (fittings) and glass (pane) are present in addition to the polyurethane. When such old windows are shredded, metal can be removed using a metal separator, while the heavy glass is separated from the lighter plastic by the influence of gravity.
- the PUR construction material used here is in particular not a polyurethane that is actively foamed by the addition of gas, but rather a comparatively heavy but nevertheless thermally insulating and mechanically very stable material that is produced by casting two components.
- the fittings are either screwed into the solid PUR construction material as is conventional or screwed in under certain circumstances during the manufacture of these molded parts.
- the window frame is fixed in the masonry of the building - alone or with the window sash already attached. It is easily possible with the above invention, integral on the masonry projecting outer frame parts, fleeces etc. directly on the floor, so that such a window can be inserted into the finished plastered and painted building from the outside in the wall opening and then fixed , so that the painting and plastering can go much faster and cheaper.
- the window frame it is useful to divide it into individual frames that are joined parallel to the main level and glue them against each other, since this means that additional equipment such as sun protection elements, wind protection elements, rain protection elements, safety elements and the like is already provided with regard to the receiving rooms or already assembled, especially in the outer frame can be included.
- additional equipment such as sun protection elements, wind protection elements, rain protection elements, safety elements and the like is already provided with regard to the receiving rooms or already assembled, especially in the outer frame can be included.
- window sash it may also make sense not to manufacture the entire window sash or window frame from two frames placed against each other and subsequently connected to each other, but to produce them in one piece by casting or foaming.
- the glass provided In the case of the window sash, the glass provided must already be inserted when foaming.
- Material providing stability as the material of the other frame parts between increase i.e. either cast in with a frame part or fasten between them when the two frame parts are fixed.
- the reinforcing frame should also preferably be used one of these three materials, i.e. usually the material of the fittings, namely metal.
- Fig. 3 a partial horizontal section through the window of Fig. 1 along the line III-III, and
- Fig. 4 a horizontal section through the central area of a two-leaf
- FIG. 1 shows a fully assembled window with a window frame 3 and attached, visible window sash 2, in which in this case several panes 4 are accommodated.
- the window frame 3 has a fighter 13, which passes under the uppermost panes 4 from the left to the right vertical leg of the window frame 3.
- FIG. 1 While the usual variant, namely the arrangement of the window frame 3 in a wall opening 14 of the masonry 12, is shown in the left half of FIG. 1, the right half of FIG. 1 shows a solution in which the window frame 13 - in the manner of a window frame - Overlaps the front of the masonry 12 on the outside and sits on this front with an outwardly projecting leg 3 ', which is, however, an integral part of the window frame 3.
- the weatherstrip 6 is also not fixedly arranged on the window sash 2 as a separate component, but rather also as an integral component.
- FIG. 2 shows a vertical section through the upper and lower end region of the window of FIG. 1.
- the window sash 2 can be opened inwards in relation to the window frame 3 and lies in corresponding folds of the window frame 3 via a molded seal 11a. Compared to conventional window constructions, however, the window sash 2 - viewed in the cross section of the representations in FIGS.
- 2-4 consists of two sash-shaped window frames 2a, 2b which are cast or injection molded into one another in a frame-like manner without joints, and which are parallel to the main plane 10 of the window , that is to say the course of the glass surfaces, are adhesively bonded to one another over an adhesive 15, and in corresponding, mutually directed folds, the insulating glass pane 4, which consists of the individual panes 4a and 4b and the circumferential seal 4c located between them, in a form-fitting manner between them, with the interposition of a molded seal 11 b.
- the weather bar 6 is also an integral, one-piece component of the outer wing frame 2a. Both sash frames 2a, 2b thus overlap the pane 4 radially inwards to such an extent that it is not possible to remove the pane 4 inwards or outwards without destroying the window sash 2, in particular its adhesive point 15.
- the window frame 3 can - as shown in the lower half of the picture - be a one-piece circumferential frame-shaped part, which in turn is also seamless, that is to say without any subsequently closed connection points at the corners, by original molds, just like the sash frame of the window sash.
- Drain openings or drain pipes 16 have preferably been molded in during manufacture or glued in later.
- the window frame 3 can also be assembled from two frame frames 3a, 3b, in particular by means of adhesive 15 being glued flat in the main plane 10.
- This has the advantage that different outer floor frames 3a can be used, which - depending on the customer's request - contain certain equipment expansions, for example the sun blind 5 shown in a corresponding cavity of this outer floor frame 3a.
- connection level between the two floor frames 3a and 3b takes place in the outermost contact surface between window sash 2 and window frame 3.
- FIG. 3 shows a partial horizontal section through the window of FIG. 1, again with a one-piece window frame 3 and with the molded part seal 11 being omitted. dividing, rung, but consists of on the outside and inside of the pane 4 rungs 7a, 7b. These rung strips 7a, 7b are in turn an integral, one-piece component of the sash frames 3a, 3b, and are thus bonded to the pane 4 by gluing these sash frames 3a, 3b to the adhesive point 15, which is preferably parallel to the main plane 10 of the window pressed, again with intermediate arrangement preferably a molded part seal 11c or 11c '.
- the two sash frames 3a, 3b are not glued to one another here, but instead are positively fixed to one another by means of a plurality of latching elements 99 distributed over the circumference.
- This is a latching element which can be pressed into corresponding recesses, that is to say blind holes or grooves, of the sash frame 3a, 3b and have barbs, so that these barbs hook into the material of the wall of the recesses.
- the window frame is shown as a one-piece frame 3.
- Fig. 4 shows a horizontal section through a window with two mutually supported window sashes 2, 2 '.
- the individual wings in turn consist of wing frames 2a, 2b or 2a ', 2b', which are formed as seamless, one-piece parts and then firmly, inseparably connected to one another in the main plane, in particular glued by means of adhesive 15.
- This has the advantage that the corresponding window sash 2 or 2 'can also be used as a single-leaf window in a corresponding window block, not shown, without a blow bar 8a or 8b, so that the number of individual elements to be produced and stored is thereby reduced.
