Art Nouveau window sash TECHNICAL AREA

1Ö The invention relates to an Art Nouveau window sash with at least one crossbar stiffening the sash and with glazing. Art Nouveau window sashes are particularly characterized by the fact that the side surfaces of the surrounding sash legs and the The sash bars are profiled. On the outside of these window sashes facing the outside of the room, the surrounding profiling has a corner formation that is at right angles in cross-section, in which the single pane of glass that was originally present in such window sashes is located. On the outside facing the inside of the room, the corresponding surfaces of the wing legs and the rungs are concavely curved.

STATE OF THE ART

^O25

The original Art Nouveau window panes still exist.

In some cases, the existing glazing consists of a single, single pane of glass, generally of low thickness. Such window sashes are no longer sufficient the structural requirements placed on them; this applies in particular to adequate thermal insulation. In the wake of today's increased awareness of energy, such windows are considered to be technically completely inadequate due to their relatively high heat transfer. recognized accordingly.

Buildings with Art Nouveau windows are often subject to the regulations of monument protection. This means that the windows

their aesthetic appearance must not be changed. Therefore, it is not possible to replace the existing technically inappropriate windows with technically modern windows,

The demands made on the grounds of monument protection

As a rule, they collide with the requirements for window sashes to have the lowest possible energy consumption for environmental reasons. A compromise between these contradictory requirements that is satisfactory to all parties has not yet been found.

O PRESENTATION OF THE INVENTION

Based on this state of the art, the invention is based on the task of specifying a possibility of how the heat transfer through the Art Nouveau window mentioned above can be reduced in a technically simple manner and at the same time the interests of monument protection can be observed.

2Q can be.

This invention is given by the features of the main claim, an Art Nouveau window of the type mentioned at the beginning is accordingly characterized in that the glazing consists of two glass panes aligned parallel and at a constant distance from one another, that in the area of the concavely curved side surfaces there is one of the two glass panes, which in its edge area on both sides is provided with a bead of putty against the curved side surface is sealed, and that openings in the wing leg &eegr; and the muntin are provided in such a way that every space between the two panes of glass that is limited on all sides is connected to the outside area surrounding the window sash by at least two openings that are spaced apart in the window plane. horizontal wing legs aligned parallel to each other. This measure creates a window with increased heat and sound insulation. The type and extent of the invention

The way in which these increased insulation properties are created for such a window has the advantage that the corresponding conversion of existing window sashes is technically simple and can be carried out without great effort. Since additional glazing is only installed on the side of the window sash facing the interior, it is practically possible to carry out the necessary conversion at any time of year; although this is usually the case, it is not absolutely necessary to replace the external glazing exposed to the outside weather when renovating the window.

U In order to enable the air in the space between the two panes of glass to circulate as effectively as possible, the openings in the window sash legs are preferably located in the upper and lower sash legs. These openings are in particular through holes. By drilling the relevant sash legs from different outer sides of the corresponding sash leg, through holes can be made in which the hole axis is bent in the longitudinal direction. This makes it possible to create exits and entrances for these holes at any point on the window sash.

prevents foreign bodies such as dust particles or small insects or the like from getting into the openings or into the space between the panes of glass.

In order to enable an improved hold of the glass pane in the concavely curved side surface area of the wing legs and bars, at least the concavely curved side surface of the lower frame leg and that of the upper side of the at least one cross bar are each provided with a groove-like notch so that the

the glass pane present there can be supported with its edge area on the walls of this notch both vertically and horizontally.

For reasons of monument protection, it has proven advantageous to use linseed oil putty.

For reasons of increased tightness, it has proven advantageous to surround the front edge area of the respective glass pane with a continuous bed of putty.

C Although the number of openings in the respective wing

schenke depends on the size of the window sashes, on the distance 3.5 between the openings and on the diameter of the respective openings, it has proven to be sensible in practice to choose the diameter of the openings or the holes so that it corresponds approximately to the thickness of a pane of glass. Finally, according to a further feature of the invention, for reasons of improved air exchange of the air present in the spaces between the panes of glass, it has proven to be very advantageous to have the hole axes of one in each of the two outer sash legs η and in the at least one

f 25 cross rungs existing through holes to be arranged flush with each other in the same - e.g. vertical - plane.

closes an opening in a surrounding frame leg, and

Fig. 2 shows an embodiment modified from Fig. 1 Q5 for an Art Nouveau window sash according to the invention.

WAYS OF IMPLEMENTING THE INVENTION

jQ A wing 10 is pivotably mounted in a surrounding frame, of which the upper frame leg 12 and the lower frame leg 14 are shown in Fig. 1, about a vertical axis in the usual ( ; manner. The left outer surface of the wing 10 forms the outside exposed to the outside weather

j5 of the same and accordingly the left outer side is the inner side of this wing 10 facing an interior not shown in detail.

The wing 10 is a so-called Art Nouveau window wing. It has profiles on its right inner side, which in this case are designed in the form of concavely curved surfaces. Thus, in the upper wing leg 16 of the wing 10 there is a concavely curved surface 18 on its lower inner side. On the upper side of the lower wing leg 20 facing the inside of the reamer 25 there is also a concavely curved surface 22.

A rung 24, which is present between the upper wing leg 16 and the lower wing leg 20 in the wing 10 and stiffens the wing in the transverse direction, also has a concavely curved surface 26 or 28 on its upper or lower outer side, similar to the upper and lower wing legs 16, 20.

Between the upper wing leg 16 and the* rung 24, in the area of the curved surfaces 18, 26, there is a glass pane 30. This glass pane 30 is mounted in a cement bed 32 or 34. The glass pane 30 is also

by means of wire pins (not shown) in the usual way both to the upper wing leg 16 and to the rung 24.

Q5 Similar to the glass pane 30, there is another glass pane 36 in the plane of the glass pane 30 between the rung 24 and the lower wing leg 20. The glass pane 36 is mounted in a putty bed 38 on the rung 24 in the area of its curved surface 28 and in the area of the lower wing leg 20 in a putty bed 40 that is present in the curved surface 22. This glass pane 36 is also attached to the () wooden rung 24 and the wooden lower wing leg 20 with wire pins (not shown in detail).

15

On the left side of the wing 10 facing the outside weather, there is a glass pane 42 or 44 between the upper wing leg 16 and the rung 24 or between the rung 24 and the lower wing leg 20, which are fastened in a known manner by means of putty beads 45 with a triangular cross section to recesses 46 in the upper wing leg 16, the rung 24 or the lower wing leg 20, which recesses are set at right angles.

/ . 25 ^In the upper wing leg 16 there is a bore 50 which opens with its lower end into the gap 52 between the glass pane 42 and the glass pane 30 from above. The other end of this bore 50 opens on the upper side 54 into the gap between this upper side 54 and the lower side 56 of the upper frame leg 12.

A similar bore 58 corresponding to the bore 50 is present in the lower wing leg 20. Its upper opening opens into the gap 59 formed between the glass pane 44 and the glass pane 36, while the lower end of this bore 58 ends on the underside 60 of the wing leg 20. In the area of the lower opening, in this

^? ' leg 20 has a recess 62 formed therein, in which the bore 58 is covered by a so-called fly screen 64. This fly screen 64 prevents dirt particles or small living creatures from penetrating into the bore 58 and thus clogging this bore 58.

The spaces 52 and 59 are connected to each other via a further hole 66 in the rung. The • outside air can thus flow from the outside through the hole 58 into the

I &iacgr;&ogr; intermediate space 59 from there through the hole 66 into the intermediate space 52 and further through the hole 50 again to

I outside - and vice versa. This creates an air leak

I ; ) exchange of the air I present in the intermediate spaces 52 and 59, so that fogging of the inside of the glass

I 15 discs are effectively prevented.

The wing 70 shown in Fig. 2 differs from the wing 10 in that the holes 50.1 and 58.1 in the upper wing leg 16 and the lower wing leg 20 open out on the lateral outer side 72 and 74, respectively. The opening areas of these holes 50.1 and 58.1 are closed with a fly screen 74, similar to the lower wing leg 20 of the wing 10, which is arranged with its outer side flush with the lateral outer side 72 and 74, respectively, for optical reasons.

&idigr; Another difference to the wing 10 is the wing

f: 26.1 and 28.1, which are located in the upper wing leg 16, the lower

; 30 wing legs 20 and rungs 24 are present, with corners 76 projecting at right angles being formed. This creates flat contact surfaces for the glass panes 30.1 and 36.1.

I 35 The glass panes 30, 36 or 30.1 and 36.1 represent additional glazing for the wings 10, 70 of a so-called youth window, which were originally already equipped with the glass panes 42, 44. With the help of these additional

With the use of glass panes, increased thermal insulation and also improved sound insulation are achieved without the visual impression of such a window being noticeably changed. The latter is of crucial importance for windows that are listed buildings and windows, since listed buildings and windows can only be improved or renovated in terms of thermal and acoustic insulation if these requirements are met.
