The invention relates to a system for fixing a glass sheet with two opposite planar, plane-parallel outer surfaces by means of a manufactured from a wooden block ingot, the glass sheet in the assembled state in a plane perpendicular to their plane-parallel outer surfaces on the wing, and by means in the assembled state against a glazing bead resting against the outer surfaces, which is made together with the wing from the same ingot.
The process for making this system comprises the following steps:

Background of the invention

Such fixation systems for glass panes, and thus in principle also their manufacturing process, are known, for example DE 20 2015 106 983 U1 (= Reference [1]), DE 20 2017 106 284 U1 (= Reference [2]) or off WO 2015 143 462 A1 (= Reference [3]).

Further state of the art

Other such systems have been offered for many years and by many companies.

For example, Holzmanufaktur Rottweil, Neckartal 161, D-78628 Rottweil offers both new productions and reconstructions of historical ones, in particular also listed, classical composite windows (see reference [4] = Internet presence http: //www.holzmanufaktur-rottweil.de/de/arbeitfelder/fenster) .
The corresponding production sequence contains the production steps a) to c), e) and g) defined above. The horizontal separating cut f) for separating the wing and the glass retaining strip is here already implied in step e) because of the geometries and the relative position of the wing and the glass retaining strip.

Modern separation windows with the features defined above offers about the company Max Wehrle GmbH, Gewerbestraße 1, D-79183 Waldkirch (see reference [5] = Internet presence http://www.wehrle-fensterbau.de/fenster/holzfenster.php ). A possible production sequence with the steps a) to c) and e) to g) is in the FIGS. 2a to 2g of the present drawing. Before the horizontal separation cut f) for the separation of wings and Glashalteleiste here a spacer bar between the blade and Glashalteleiste is inserted to counteract pressure forces in the vertical compression of the machined wood block and the simultaneous cutting surfaces simultaneously in their geometry, in particular their relative distances as accurate and true to scale to be able to produce.

A similar production process, which also comprises steps a) to c) and e) to g), is described in US Pat FIGS. 3a to 3g of the present drawing. The fixation system shown again has all of the physical characteristics defined above and is offered by the company Fenster Dörig AG, Blattenheimatstrasse 2b, CH-9050 Appenzell (see reference [6] = Internet presence http://www.doerig.ch/unternehmen/ production.html) .

Compared to the system described above Fig. 2 here the separation cut in production step f) is somewhat finer due to the special geometry and the relative positions and dimensions of wing and glass retaining strip, so that in step a) correspondingly an ingot with smaller vertical dimensions than in the system according to reference [5] can be selected.

Common to the above-discussed known fixation systems for glass panes, inter alia, that the two surfaces of the wing and the glass retaining strip, which in the separation - usually in the manufacturing step f) - are generated later in the assembled dressing in assembly step g) together Plant come or face each other, and that these two surfaces must therefore be processed particularly accurate to size, which either requires time-consuming and expensive rework or a particularly fine and thus again consuming separation section. In addition, the high standards of dimensional accuracy in this manufacturing step mean that even in step a) an ingot must be provided with significantly larger vertical dimensions than would actually be necessary in view of the vertical final dimensions of the assembled dressing. This is then inevitably an increased consumption of wood.

Further disadvantages of the known systems also arise from the following facts:
In the current state of the art should be between the weather-side outer surface of the glass retaining strip and the wooden frame or optionally a rain rail a defined gap of 0.5 to 1mm to ensure optimum tightness of the overall element. In the separation method according to the prior art is due to the increased tolerance in the separation step f) increases this gap width in order to prevent blocking of the lacquer layer of both elements, which can lead to a reduced overall tightness of the element.

Furthermore, according to the state of the art, the separation cut is always carried out completely. This involves not insignificant safety risks, since the separation cut the two parts are completely detached from each other at the last moment of the separation process and thereby a setback behavior due to the counteracting direction of rotation of the release agent to the feed direction of the two now separate workpieces. This applies in particular if the mechanical force of the feed to the frictional resistance of the support side is in gross disproportion.

As in the FIGS. 3a-g to recognize the drawing, a screwing the weather-side glass retaining strip by means of mechanical spacer is carried out at a distance according to the prior art. This has the considerable disadvantage that a screw is in the vicinity of the weathering, which can lead to condensation and moistening of the wood construction. Furthermore, there is always an interruption of the paint layer in the weathering area due to the screw, which can lead to paint breakage and thus to lack of wood protection.

Also, in the prior art, positioning occurs during assembly of the glazing bar on the existing sash, at best, via a groove or a groove present parallel to the glazing surface. A positioning which takes place parallel to the outer glass contact surface results exclusively from the parting surface produced in step f), which as a rule is only of minor size Dimensional accuracy will be. However, this design disadvantage does not have any positive effects on the tensile forces on the load of the corner joint, which is of crucial importance in the overall construction due to higher glass weights.

Another significant drawback in the prior art separation process is the negative effects on thermal conductivity relative to the provision of the ingot (see Figures 2b and 3b ) in relation to the mounting condition (see FIGS. 2g and 3g ), which can be explained by the fact that the ingot has a higher strength than sash and glazing bar in the assembled state.

Another disadvantage of the prior art is that usually the separating cut (according to FIGS. 2f and 3f ) takes place after the composition and compression of four elements to a sash. A required constructive 6-sided wood protection of all parts is therefore usually not present in the separation process of the current state of the art.

Finally, a further disadvantage of the current state of the art is that without static Scheibenverklebung the wind load and possibly a suction effect physically act on the contact surface between casement and Glashalteleiste.

Object of the invention

Object of the present invention is in contrast, with the simplest possible technical means to provide an inexpensive and cost-effective system of the type described above for fixing a glass, which is particularly easy to handle and should be universally applicable, the need for a special faithfulness and high manufacturing accuracy in the production of the interfaces between the wing and Glashalteleiste should be avoided. However, the system should still allow precise positioning of the system parts relative to each other. Last but not least, the fixation system should also allow for at least largely non-destructive outgassing. Finally, it is also an object of the invention to compensate for the length of the inner sash to the outer Glashalteleiste due to their changed position so that they again correspond to the required length in the assembled state, and require no rework.

Brief description of the invention

According to the invention this relatively complex task with respect to the production of the system and thus also by the associated process product in a surprisingly simple and effective way solved in that the calibration of the ingot in step b) only on the exact subsequent height of the wing and Glashalteleiste done in the assembled state, wherein the thickness d _{T of} the horizontal separation section in manufacturing step f) is not added to the calibration thickness; that between production steps c) and e) a further manufacturing step d) is inserted, namely
d) Vertical profiling by means of a vertical separating cut between the sash and the glazing bead;
that before the assembly of wing and glazing bead in the assembly step g) the manufactured and the wing in step f) completely separated glass retaining strip relative to the wing by 180 ° is rotated with respect to a vertical axis of rotation - and is thus positioned in relation to the inner and outer profiling of the association in such a way that the length of the glass retaining strip in the assembly step g) is correct again;
and that the glass retaining strip is mounted in the assembly step g) relative to the wing such that the glass retaining strip rests in the assembled state of the system with a surface on the bottom surface of the wing, but not with their cut surface at the cut surface produced in the horizontal separation cut in manufacturing step f) of the wing, which was generated simultaneously by the horizontal separating cut in production step f).

Alternatively, in step f), instead of a complete separation, a predetermined breaking point between glass retaining strip and wing can also be inserted.

In any case, the positioning of the glass retaining strip relative to the wing between step f) and the assembly step g) always takes place in such a way that the length determination of the strip is again correct in relation to the mounting state.

Operation of the invention and other advantages over the prior art

Thus, the present invention proposes a system for fixing a glass pane, which makes it possible to fix the glass pane, for example, on a window or door frame with the aid of a glazing bead. The system is characterized by the fact that the separated glazing bead before its assembly with the wing -simultaneously made of the same wooden ingot is rotated relative to its position during manufacture by 180 ° with respect to a vertical axis of rotation.

This-appearing, but central-measure allows a relative position of wing and Glashalteleiste during their simultaneous simultaneous production from the ingot, which allows in step b) to calibrate the ingot only to a vertical height, the only the exact later height the assembly of wing and glass retaining strip in the assembled state, but not - as in the prior art mandatory required - also the thickness d _{T of} the horizontal separating section in manufacturing step f) contains. Thus, an ingot with a smaller vertical height can already be provided in production step a) than would be possible in the prior art.

Due to the above-described rotation of the glass retaining strip by 180 ° before its assembly with the wing completely different contact surfaces between the wing and glass retaining strip can now be selected as the cut surfaces produced during horizontal separation in step f) between the two parts of the association. The plane which defines the connection between inner and outer frame wings, ie between the wing and the glass retaining strip, is no longer generated by the separating cut in the system according to the invention, which is why tolerances arising during the separation of the two elements are no longer relevant - as opposed to all other known systems. Since the quality of the two contact surfaces is of particular importance for the quality of the fixation system produced, this results in quite different and significantly improved possibilities for the cost-effective, but nevertheless true-to-scale and functionally reliable production of such systems.

Further, the system according to the invention is particularly simple and inexpensive in terms of manufacture and assembly. It is largely independent of the type of glass used used. Since the system has only low tolerance requirements, it is almost universally applicable, especially for very different glass thicknesses. Nevertheless, the system does not require a larger number of individual elements compared to prior art systems known in the art.

Also, a glass sheet can be largely vitrified nondestructive, so that then the system can be used again for fixing. Thus, for example, a repair of a window or a door with glass is considerably simplified.

Preferred embodiments of the invention

Embodiments of the invention are very particularly preferred in which the horizontal separating cut in production step f) is carried out without prior insertion of a spacing strip between the wing and the glass retaining strip. In this last manufacturing step f), both in the prior art and in the invention, it is absolutely necessary to guide the dressing to be processed from above and below during the horizontal parting cut, for example by means of mechanical clamping or feed rollers. For this purpose, a certain back pressure is exerted on the bandage. But while in the present invention, this backpressure only on the top and the bottom of the separated blade (see Fig. 1f ), in the prior art always the pressure from above on the top of -before this last separation cut still in association with the Glashaltleiste located- wing, which exerted from the bottom, however, on the bottom of -not yet separated-glass retaining strip. For safety reasons, however, no pressure must be applied to the saw blade of the saw, which would otherwise lead to a kickback behavior in the separation process. Therefore, in the procedure according to the prior art, the use of a fairly precise spacer strip with a relatively small length tolerance between the blade and the glass retaining strip is absolutely necessary (see FIGS. 2f and 3f ), which in the invention, however, can be completely eliminated. In this way, cost savings and significant quality improvements in the finished product are achieved with the invention.

In further advantageous embodiments of the invention, in production step d) together with the vertical separating cut between the blade and the glazing bead, a vertical groove is also simultaneously milled into the lowermost surface of the blade. This results in a defined area for the introduction of an adhesive which statically connects wings and glazing bead to absorb tensile and shear forces acting on the wing due to high glass weights. A joint permeability between the sash and the glazing bead is reliably prevented when an adhesive is introduced.

Therefore, it is also particularly advantageous if, prior to the joining of the wing and the glass retaining strip in the assembly step, g) adhesive is introduced into the vertical groove.

In practice, embodiments of the device according to the invention, in which prior to the assembly of Wing and glass retaining strip in the assembly step g) a sealing element and / or insulating material introduced into a gap between the wing and Glashalteleiste and / or the gap is designed as a constructive air gap with thermal insulation properties. This leads to significant improvements in the heat transfer coefficients ("lambda") of the overall construction. Even without a separate insulating material can be achieved in this embodiment, due to an air chamber, a much better lambda value. The economy of this embodiment is explained by the complex construction such as a special Kantel - such as the manufacturer Holz-Schiller, Pointenstr. 24-28, D-94209 Rain (see their Internet presence in reference [7]) offered product "Airotherm® window cover". By using the gap dimension as an insulation layer, the high procurement investment in higher raw block goods, as in the FIGS. 2a and 3a shown is omitted.

Further advantageous embodiments of the invention are characterized in that the production step f) does not have to be carried out as a complete separation cut, but the separating cut is carried out so that it leads to a predetermined breaking point, whereby the glass retaining strip is carried in the further manufacturing process, and as needed in the Manufacturing process can also be separated manually. The predetermined breaking point has no influence on the rest of the construction. This is of considerable economic importance, especially in the subsequent work processes of the grinding and painting process, because no duplicate part tracking through the manufacturing process is necessary.

Particularly preferred embodiments of the invention, in which the glass retaining strip in the assembly step g) relative to the wing is arranged such that the glass retaining strip in the installed final state of the system faces the weather side. Advantages arise from the fact that the ingots according to FIGS. 1a, 2a and 3a In practice, each consist of multi-layered horizontal slats, which are constructed because of their weather-side position of a particularly weather-resistant or modified wood - in contrast to the room-side wooden slats, which in particular unfold an aesthetic effect. This serves the economic efficiency, in particular both by a longer life cycle of the product as well as a smaller use of warranties due to defect announcements.

Preferred developments of these embodiments of the invention provide that a different surface treatment of the outer surfaces of the later wing and the later Glashalteleiste done in machined ingot, so that in particular two different colors of the later wing and the later Glashalteleiste are caused. Advantages are that using a cut-cut with predetermined breaking point, the first two operations of wood coating, usually impregnation and priming, can be done on the connected workpiece, whereby significant material savings can be achieved with respect to overspray. Preferably, then, and before the final painting, the workpiece is separated into sash and glazing bead to produce different color surfaces of the sash and the glazing bead.

The scope of the present invention also includes fixation systems prepared according to the method of the invention described above.

In this case, in the case of a first class of embodiments, the wing in the installed state of the system can be designed as a fixed, non-movable frame part.

An alternative class of embodiments is characterized in that the wing in the assembled state of the system is designed as a movable, in particular pivotable frame part.

Particularly preferred is also an embodiment in which a latching element is provided in the assembled state between the wing and glass retaining strip. This is of particular importance, since both extreme wind loads and suction effects on large window surfaces with high wind resistance can lead to buckling of the glass pane. The locking element in the particular embodiment fixes the disc and creates a pressure already during the screwing, so that the glass pane is limited in its ability to move. The latching element thus assumes the function of a somewhat more complicated form of glass bonding in this embodiment.

In addition to the wing and glass retaining strip, in further embodiments of the invention, one or more further frame parts, preferably also made of wood, can be provided.

In one class of advantageous embodiments, the fixing system has an elongated damping element on its glass-side outer surface in the assembled state, which can be pushed, glued, welded, foamed or sprayed on in particular. This achieves considerable damping of the effective pressure at the end fitting. This It also makes it possible to define the height of the fixation system so that a glazing gasket (see below) can be inserted.

In supplemental or alternative developments, it is advantageous if a flow barrier is provided which prevents uncontrolled air exchange between an outer surface of the frame and an outer surface of the glass sheet. This makes it possible for the window frame to have a high thermal resistance, which makes it possible to produce particularly energy-efficient, energy-saving windows. Also, this can prevent unwanted condensation. This is done by forcibly parallel sliding the glass retaining strip on the fixing element. Thus, the glass retaining strip is pressed onto the wing, which in turn prevents an air flow.

Furthermore, in advantageous embodiments of the invention, a sealing element between the glass retaining strip and the glass pane may be provided, which engages in the mounted state in a sealing groove of the glass retaining strip. With this configuration, this sealing element can press against the glass pane and be supported on this. As a result, it can press the glass retaining strip against the self-locking element and thus build up or maintain a pressure necessary for locking the glass pane.

Finally, in embodiments of the invention, the thermal resistance of the window can be optimized if a preferably thermally insulating top strip is arranged in the assembled state between the wing and the glass pane.

The individual features may be implemented individually for themselves or for a plurality of combinations in variants of the invention.

The production of such a fixation system basically comprises the following steps, which are already known from the prior art , in particular from the FIGS. 2 and 3 can be seen:

• a) providing the ingot 00 from wood;
• b) Calibration of the ingot 00 by planing to a calibration thickness D _K , that of the exact later height of a band consisting of the wing 11 and the glazing bead 12 in the assembled state, optionally plus the thickness d _{T of} a horizontal separating cut in the separation of the wing 11 and glass retaining strip 12 during manufacture in step f), corresponds;
• c) internal profiling of the bandage of wing 11 and glass retaining strip 12 on the glass pane in the mounted state of the system side facing the wing 11;

• f) performing a horizontal separating cut to separate the wing 11 and the glass retaining strip 12 in the ingot 00 processed in steps b) to e); such as
• g) assembly of the system with assembly of wing 11 and glass retaining strip 12th

The cut is at Fig. 2f presented finer than at Fig. 3f , In Fig. 3g the glass retaining strip is held at a defined distance by means of a mechanical screw connection.

As in the FIGS. 1a to 1g illustrated, the present invention is characterized
that the calibration of the ingot 00 in manufacturing step b) takes place only on the exact later height of the wing 11 and glazing bead 12 assembly in the assembled state, the thickness d _{T of} the horizontal separating cut in manufacturing step f) not being added to the calibration thickness;
