Window

Description

The invention relates to a window of the type specified in the preamble of claim 1.

When designing building facades, aesthetic considerations must be taken into account in addition to technical and economic

Viewpoints are of central importance. Requirements profiles arise in which aesthetic considerations - possibly in connection with or directly in the form of monument conservation requirements - seem to force technically outdated or in the specific case inapplicable and/or economically unviable solutions. Typical examples of this are the reconstruction of historical or regionally typical facades or the adoption of stylistic elements of such facades when constructing new buildings.

Such contradictions are particularly evident in the construction of windows or - more generally - transparent facade sections, since the functional differences between modern solutions and "classic" constructions are particularly profound and technical concessions are only permissible to a very limited extent in view of current standards, which, for example, require the realization of certain heat and sound insulation values or workplace parameters.

The use of sliding windows - just like casement windows - is practically impossible today in multi-story office buildings due to the existing energy and ergonomic requirements. However, such windows are a distinctive and widespread stylistic element of buildings from the American cultural sphere as well as of classical modern buildings. Therefore, in connection with the reconstruction of such buildings and the use of the style in new buildings, there is a need for a modern window construction with a corresponding external appearance.

The invention is based on the object of specifying such a window construction.

This object is achieved by a window having the features of claim 1.

The invention includes the idea of providing a window that is essentially fixed in glass and can therefore be implemented with the thermal and sound insulation parameters required today and complies with today's occupational health and safety regulations, with the external appearance of a sliding window but without its opening function.

In a first embodiment, which has the external appearance of the vertical sliding window, which is particularly common in North America, the first glazed section is located above the second glazed section in the installation position of the window and its glazing area is offset from that of the second section towards the outer shell of the building.

The specified construction can also be used to implement corner solutions in which two first and two second sections are provided, the planes of which intersect, in particular at a right angle, and in which an upper corner section is formed that is offset from a lower corner section towards the outer skin of the building. For this purpose, a separate corner connector with a cross-section that is essentially L-shaped or double-L-shaped is specifically proposed. This has in particular a corner connector that is offset from the extension planes of the corners that are connected to one another at the corner angle.

running frame profile parts bevelled front section, but can also be designed without a sockhe bevel.

As an alternative to the vertical sliding window (or possibly in combination with it on one and the same facade), the invention makes it possible to produce a modern window with the external shape of a horizontal sliding window, in which the first glazed section is arranged to the side of the second glazed section in the installation position of the window and is offset in depth relative to it.

In both designs, the first and/or the second glazed section can be divided by a second frame profile part (and optionally further sections) into at least two sections, which then lie in one and the same extension plane. In accordance with the most common style patterns, the second and the optionally provided further frame profile part(s) run parallel to the first frame profile part, which provides the external appearance of the sliding guide.

In this case, at least the second frame profile part is preferably designed to protrude by 2 to 10 centimeters, preferably by 4 to 6 centimeters, towards the outer skin of the building compared to the first frame profile part in the installation position of the window, thereby expressing a limitation of the apparently sliding section.

The first frame profile part has a recess in the frame for the offset mounting of the two glazing surfaces.

Cross-section essentially L-shaped or double L-shaped profile element, with which the window can be manufactured economically. To save weight and to facilitate the realization of different surfaces with the same basic structure, preferably at least the first frame profile part has a core profile part and a casing profile part arranged on the outside of the building, with the glazing areas being limited by the casing profile part. In addition, a casing profile part arranged on the inside of the building can - and usually is - also be provided. This can be made of a different material than the outer casing profile.

In a particularly easy-to-assemble composite structure, the core profile part has clamp-like recesses on its surface facing the shell profile part and the shell profile part has port sets on its surface facing the core profile part that correspond in shape to the recesses, such that the shell profile part can be pushed onto the core profile part and is held thereon essentially by frictional engagement of the extensions in the recesses.

Both the core part and the shell profile part (or the shell profile parts) are expediently - simplified - essentially designed in an L or double-L cross-sectional shape.

From a monument conservation point of view, for the reconstruction of buildings of classical modernism (in which steel window frames were widely used) interesting

sant is a special design in which all frame profile parts have a light metal core profile part and a steel casing profile part that essentially completely covers the core profile part on the outside of the building when the window is installed. Of course, depending on the desired external effect, other material combinations are also possible, such as with polyamide for the casing parts, although the technologically sophisticated structure with a light metal core is generally used.

Advantageous further developments of the invention are characterized in the subclaims or are presented in more detail below together with the description of the preferred embodiment of the invention using the figures. They show:

Figure 5 is a cross-sectional view of the structure of the frame profiles in a special version of the window shown in Fig. 1.

Fig. l shows a perspective view of a window 1 with the external appearance of a vertical sliding window, which has an upper part 2 divided into two separate glass surfaces 2a, 2b and a lower part 3 divided in the same way into two glass surfaces 3a, 3b. The glass surfaces 2a, 2b, 3a and 3b are plane-parallel to one another and are all the same size. In modified versions they can also be of different sizes; for the intended visual impression, however, it is advantageous if at least the lower glass surface 2b of the upper part and the upper glass surface 3a of the lower part are the same size.

The glass surfaces of the window upper part 2 and the lower part 3 are - with the exception of the edges with which they adjoin one another - framed in conventional frame profiles 5 and 6 respectively. A horizontal profile part 5a and 6a with a likewise conventional structure separates the partial surfaces from one another and frames one of their edges, while a special profile part 4 with (in simplified terms) a double L-shaped cross-section is provided between the upper and lower parts. As can be seen in the figure, the surface of the upper part 2 is offset towards the front compared to that of the lower part 3, i.e. towards the outside of the building. The dividing profiles 5a, 5b protrude slightly towards the front compared to the profile part 4.

LIH46.G1 Sheet 8

The overall arrangement outlined creates the visual impression of a classic vertical sliding window for the distant observer, although all glass surfaces are immobile and the window's construction as a whole meets all current heat, sound and occupational safety requirements.

In a modified embodiment, sections of the window shown in Fig. 1 can also be movable, for example tiltable. Furthermore, such windows can be arranged directly next to one another, particularly horizontally.

In Fig. 2 - in a schematic perspective detail - a window 11 with the external appearance of a horizontal sliding window is shown in an alternative embodiment of the inventive concept to Fig. 1. The window II is divided by a centrally vertically running profile part 14, which has an L-shape in cross section (shown in simplified form) into two parts 12 and 13 which are offset from one another in the depth direction of the facade and are plane-parallel to one another, and the part 12 on the left in the drawing is again divided into two separate glass surfaces 12a, 12b by a vertically running profile part 15a of a frame 15, while the frame 16 of the right part 13 is "continuously glazed".

With this design, too, a wide range of modifications are possible in order to adapt to the specific application requirements through different (even finer) surface division, tiltable or swiveling design of one or more parts, direct arrangement of one or more elements, etc.

Fig. 3a shows a schematic diagram of a corner window 21 according to a third embodiment of the invention, which comprises a corner upper part 22 with two glass surfaces 22a, 22b at right angles to each other and a corner lower part 23 set back from this with two glass surfaces 23a, 23b also at right angles to each other and in which a special corner connection is provided with frame parts 25, 26 inclined at 45° to both glass surfaces and a corner connector 27. The frame parts 25, 26 and the (simplified representation) double-L-shaped frame parts 24a, 24b separating the upper from the lower part of the corner window converge in this.

Fig. 3b shows the corner connector 27 in a detailed representation of the embodiment according to Fig. 3a in its basic structure. Here, the ends of the horizontal frame parts 24a, 24b from Fig. 3a (also greatly simplified) are shown inserted into corresponding recesses 27a, 27b of the connector, while grooves 27c, 27d for receiving end sections of the vertical frame parts 25 and 26 are only indicated and these frame parts themselves are not shown in Fig. 3b. It can be seen that the connector has beveled end faces 27gl and 27g2 opposite both side flanks 27e, 27f.

Fig. 3c shows a modified connector 27' compared to the corner connector according to Fig. 3b, which does not have a bevelled front surface, but rather has side flanks 27e', 27f that are perpendicular to one another and can therefore be used in a window structure similar to Fig. 3a with correspondingly right-angled vertical profiles that form the right-angled

window sections running one above the other. (The remaining parts of the corner connector 27' correspond to those shown in Fig. 3b, are therefore designated with corresponding reference numbers and are not explained again here.)

Fig. 4 is a perspective schematic representation of a multiple arrangement 31 of two windows HA', HB' with the structure of the second embodiment (Fig. 2) and a corner window 21 according to the third embodiment (Fig. 3a). The reference numerals of the figures mentioned were adopted for the individual windows or a designation based on them was chosen. The connection between the corner window and the adjacent windows is made by two profiles 27A, 28A and 27B, 28B arranged vertically in their longitudinal direction, whereby the profiles 28A, 28B have a similar L-profile to the profiles used in the individual windows to create the surface offset between the window surfaces 12A ¹ and 23b or 23a and 12B ¹ to create the surface offset. The figure shows an embodiment in which the frame parts 24b, 27A and 28A or 24a, 27B and 28B abut one another; in a suitably modified embodiment, a three-dimensional angle connector is provided instead, into which all frame parts can be inserted.

Similarly, a corner window can also be combined with two windows according to the first embodiment, or windows according to the second and third embodiments can be combined with each other in one and the same facade at a corner without the corner window according to the third embodiment being used.

Fig. 5 is a vertical cross-sectional view of the structure of some frame profiles in a special version of the window 1 shown in Fig. 1. The parts already shown and described there are not described again here. The course of the glass surfaces is only indicated in Fig. 5.

As can be seen in the figure, the profile parts 4, 5a and 6a (as well as the other profile parts, which cannot be seen in the figure) have a core-shell structure, whereby the core parts 50a and 60a are each in two parts and an outer and an inner shell part 51a, 52a or 41, 42 or 61a, 62a is provided. All shell parts are provided with extensions (not individually designated in the figure) pointing inwards towards the respective core part in the installed position, and the core parts have clamp-like recesses in the corresponding position, into which the extensions of the shell parts engage and in which the shell parts are therefore held on the core parts. The core parts 40, 50a, 60a are made of standard light metal profiles, while the shell parts 41, 42, 51a, 52a and 61a, 62a are made of sheet steel.

The invention is not limited in its implementation to the preferred embodiment given above. Instead, a number of variants are conceivable which make use of the solution presented even in fundamentally different embodiments.
