Wooden window or wooden door

The invention relates to a wooden window or a wooden door with a sash frame and/or an inner frame or a wooden casing and a door sash frame, each of which is provided with replaceable outer shells.

Such wooden windows or wooden doors are well known.

Since the outside of windows is exposed to the weather, precautions must be taken to prevent premature weathering of these external areas.

The most common form of this is to regularly paint these external parts, but this is time-consuming and laborious and therefore is often not carried out in time to provide adequate protection against weathering.

A somewhat less complex protective measure for these wooden windows and doors is to place aluminum shells on the corresponding wooden frames, preferably clipped on using appropriate fastening parts.

Although these aluminum shells offer some longer protection against weathering than the normal paint, these aluminum shells are disadvantageous for several reasons.

On the one hand, wooden frames are often preferred for architectural aesthetic reasons. In addition, aluminum and plastic parts are opposed to the ever-increasing ecological awareness. In addition, these metal and plastic parts are usually not manufactured in the factories that manufacture wooden windows and doors. They must therefore be purchased from suppliers, which can lead to bottlenecks, which can delay the production of wooden windows and doors.

On the other hand, condensation can form between the aluminum shells and the actual wooden frame because the aluminum cools down more quickly. This condensation can also lead to weathering of the wooden frames, which can usually only be detected too late due to the covering.

The invention is therefore based on the object of specifying a wooden window or a wooden door of the type mentioned at the beginning, which enable an easy replacement of the outer shells using technically simple means and at the same time have more ecologically compatible materials.

This object is achieved according to the invention in a wooden window or a wooden door of the type mentioned at the beginning in that the outer shells are replaceable wooden shells which are held in a form-fitting manner by means of a detachable tongue and groove connection.

This simple tongue and groove connection means that the wooden shells can be easily and quickly replaced if, after a certain period of time, they have become so weathered that a new coat of paint would actually be necessary.

The installation of the wooden shells can be made even easier if the tongue and groove connection is essentially aligned parallel to a corresponding pane of glass. This makes it possible to place the corresponding wooden shells on the corresponding frame parallel to the pane of glass and to bring the tongue into engagement with the corresponding groove by simply moving it.

To make it easier to fix the wooden shells, it is advantageous if the wooden shells arranged vertically for the frame or for the casing or for the sash frame or for the door leaf frame cover their entire length, while the wooden shells arranged horizontally rest with their respective front sides clamped against the vertical wooden shells.

Of course, it is also possible to provide a reverse arrangement, so that the vertical wooden shells are clamped to the horizontal wooden shells with their respective front sides.

Although the clamping effect is sufficient to fix the wooden bowls in place if the dimensions are appropriate, it can be advantageous in the event of extreme temperature fluctuations if the wooden bowls are additionally fixed with their clamped ends. These additional fixations can be screws, for example stainless steel screws, or other holders.

Of course, it is also possible to apply the invention to casement frames or door frames that additionally have central sections or collars.

The same applies to window frames or wooden casings that also have transoms, i.e. horizontal crossbeams that divide the window or door, and/or set timbers that divide the window or door vertically.

Although the attached outer shells are made of wood and thus the risk of condensation is greatly reduced, the wooden shells can still be ventilated from behind.

Additional fixing for the wooden shells attached to the frame is possible if the wooden shells for the inner frame or for the wooden casing have a groove on the side facing the outer edge of the wooden window or wooden door, into which a projection of a plaster strip can engage.

Furthermore, the invention makes it possible to use types of wood for the wooden bowls that are more suitable for outdoor use, such as robinia wood, cedar wood, and similar types of wood.

It is also possible to create a two-tone design for the windows without much effort, giving the outside and inside different colors.

The wooden windows or wooden doors according to the invention therefore have a two-part wooden structure, with the inner frame and the sash frame or the wooden frame and the door sash frame taking on the load-bearing and thus static functions.

The wooden bowls are easy to replace as they feature a simple fastening technique.

The same applies to the wooden shells of the inner frame, which have the same simple fastening technology.

Further features and advantages of the invention emerge from the following description of several embodiments and from the drawings to which reference is made. They show:

Fig. 13 is a schematic representation of the installation of the wooden frames.

With reference to Figures 1 to 13, several embodiments of wooden windows are now described, whereby the same reference numbers designate the same window parts.

Although only wooden windows are described below, the following description also applies to wooden doors.

As shown in Fig. 1 to 5, a wooden window has a sash frame 10, in which a glass pane 30 is fitted with corresponding sealing elements, not further described.

When closed, the sash frame 10 abuts against a frame 12, with a seal (not specified in more detail) also being fitted between the sash frame 10 and the frame 12.

The sash frame 10 has on its outer side a spring 24 running essentially parallel to the glass pane 30.

A vertical or horizontal wooden shell 14 and 16 with a groove 22 can be attached over this spring 24.

As can be seen from Fig. 1 and 2, the vertical and horizontal wooden shells 14 and 16 for the sash frames 10 are identical in cross-section, which is not mandatory but is advantageous with regard to production and storage.

Furthermore, Figures 1 to 5 show vertical and horizontal wooden shells 18 and 20 for the frame 12. These wooden shells 18 and 20 also have a groove 26 into which a spring 28 arranged along the frame 12 in a similar manner to the spring 24 for the sash edge 10 engages.

As can be seen from the drawing, the edge of the vertical and horizontal wooden shells 18 and 20 for the frame 12 facing the outer edge of the window is provided with a groove 38. A tongue 40 of a plaster strip 42 attached to the masonry engages in this groove 38 as an additional holder for the vertical and horizontal wooden shells 18 and 20 of the frame 12.

In the embodiments shown, this plaster strip 42 has an additional spring that engages in corresponding grooves in the frame 12. This ensures exact mutual positioning of the spring 28 of the frame 12 and the spring 40 of the plaster strip 42 for the attachment of the wooden shells 18 and 20.

The sectional partial views shown in Fig. 3 and 4 are variants of the embodiment shown in Fig. 1 and 2 and differ only by an additional arrangement of a roller shutter strip 44 on the vertical wooden shell 18 for the frame 12, see Fig. 3, or on the plaster strip 44, which is shown in Fig. 4. The other arrangements of the wooden shells 14, 16, 18 and 20 are the same as in the respective

Some of Figures 1 and 2 are identical, so that a further detailed description is not necessary.

The same applies to the sectional partial view shown in Fig. 5, which merely shows the embodiment according to Fig. 3 in a horizontal section.

The embodiment shown in Fig. 6A and B and 7A and B differs from the previous embodiments in that it shows a wooden window with fixed glazing, i.e. a window that cannot be opened.

Since this wooden window cannot be opened, it does not have a sash frame, but only a frame 12.

This means that in this embodiment, only vertical and horizontal wooden shells 18 and 20 are used for the frame 12. The tongue and groove connection is identical to the previous embodiments, so that a more detailed description is not provided.

For the lower horizontal wooden shell of the frame 12, a cross-section identical to the vertical and horizontal wooden shells 14 and 16 for the sash frame 10 can be used. Below the wooden shell 16, the frame 12 is covered by a drip profile 4 6, which is usually made of aluminium or copper.

The upper horizontal wooden shell 20 and the vertical wooden shells 18 are identical in cross-section and correspond to the previous embodiments in terms of the tongue and groove connection.

The only difference is that the end area facing the glass pane 30 has the same bevel as the wooden shells 14 and 16 of the sash frame 10 of the previous embodiments .

Of course, it is also possible in this embodiment to provide a roller shutter strip 44 on the vertical wooden shell 18 for the frame 12, which is shown in Figure 7B.

Figures 8 to 10 show another embodiment in three variants. In this embodiment, the different attachment options for the wooden shells 14, 16, 18, 20 for a wooden window are shown, which has a transom 34, i.e. a crossbeam that divides the window into a skylight and a lower window section.

The variations are that, according to Fig. 8, the skylight has fixed glazing and the lower part of the window is a window sash. The variant of Fig. 9 is arranged exactly the opposite of that of Fig. 8, while the variant of Fig. 10 provides a sash for both the skylight and the lower part of the window.

In the sectioned partial view according to Fig. 8, which shows a vertical cross-section, the horizontal wooden shell 20 of the frame designed as a transom 34 is identical in cross-section to the vertical and horizontal wooden shells 14 and 16 of the sash frame 10 according to the embodiment of Figs. 1 to 5. Here, too, the horizontal wooden shell 20 is attached to the transom 34 in an identical manner via a tongue and groove connection.

The horizontal wooden shell 20 for the lower part of the window, which has a sash frame 10, has a cross-section identical to that of the vertical wooden shell 18 of Fig. 4. Here, too, the same tongue and groove connection is used as

described above to fix this horizontal wooden shell 2 0 to the transom 34.

The horizontal wooden shell 16 for the sash frame 10 of the lower window part is identical in cross-section to the upper wooden shell 16 of Fig. 1, so that here too the same tongue and groove connection, as already described, fixes this wooden shell 16.

As can be seen in Fig. 8, the horizontal wooden shell 20 attached to the transom 34 is additionally fixed to the upper edge facing away from the lower part of the window by means of a strip 42 which corresponds to the plaster strip 42 and engages in a groove of the transom 34 with a spring for additional support.

The variant shown in Fig. 9 has a lower window part with fixed glazing, while the skylight can be opened.

To simplify production, the lower horizontal wooden shell 16 for the wing edge 10 also has a cross-sectional shape that was also used for wooden shells in the previous embodiments. In this case, the lower horizontal wooden shell 16 of the skylight is identical in cross section to the lower horizontal wooden shell 20 of the skylight according to Fig. 8.

The upper horizontal wooden shell 20 for the lower window part is similar in cross-section to the upper horizontal wooden shell 16 according to Fig. 8, but has a groove at the end facing away from the glass pane 30, into which the same strip 42 according to Fig. 8 engages. The transom 34 is covered by a drip profile 46 that overlaps the strip 42.

The variant shown in Fig. 10 is a combination of the two variants according to Fig. 8 and Fig. 9, whereby only the window parts with fixed glazing are replaced by casement window parts

were replaced.

Accordingly, the horizontal wooden shell 16 of the skylight is identical to the horizontal wooden shell 16 according to Fig. 9.

The same applies to the arrangement of the transom 34 and the sash frame 10 for the lower part of the window, which is identical to the arrangement of the transom 34 and the sash frame 10 according to Fig. 8. Therefore, a further detailed description is unnecessary.

Fig. 11 and 12 show two embodiments of a wooden window with two pivoting wings.

In the embodiment shown in Fig. 11, when the window is closed, the two adjacent vertical parts of the sash frame 10 strike each other, with the joint between the sashes being covered in the closed state by a cover 32 attached to the left sash part of the sash frame 10 in Fig. 11.

The vertical wooden shells 14 shown in Figure 11 for the respective casement frames 10 are identically designed and attached as the vertical wooden shell 14 for the casement frame 10 according to Fig. 2.

Fig. 12 shows an embodiment in which a vertically arranged setting piece 36 divides the wooden window for optical and/or stability reasons.

The two parts of the sash frame 10 facing the setting wood 3 6 with the corresponding vertical wooden shells 14 are identical to the right sash part according to Fig. 11, whereby the left sash part of Fig. 12 is of course designed as a mirror image of the right part.

The further difference between this embodiment and that of Fig. 11 is that the outside of the frame, which is designed as a set piece 36, is provided with two vertical wooden shells 18. These two wooden shells 18 have the same tongue and groove connections as all the other embodiments already described with regard to the set piece 36. However, additional fixing is provided by the fact that the vertical wooden shell 18 on the right in Fig. 12 has a tongue which engages in a groove in the vertical wooden shell 18 on the left in Fig. 12 for fixing.

Using Fig. 13, we will now briefly describe how the individual wooden shells 14, 16, 18 and 20 are attached to the sash frame 10 or the frame 12.

Fig. 13 shows a fixed glazing in the upper area, while a window part with sash is shown in the lower area.

If the wooden shells 14, 16, 18 and 20 are to be renewed or refitted, the vertical wooden shells 14 and 18 are moved outwards against the sash frame 10 or the frame 12 in parallel alignment to the glass pane 30 as shown in Fig. 13, so that the corresponding grooves 22 and 26 accommodate the associated springs 24 and 28.

If the vertical wooden shells 14 for the sash frame 10 or 18 for the cover frame 12 are inserted accordingly, the corresponding horizontal wooden frames 16 for the sash frame 10 and 20 for the cover frame 12 can be inserted between the vertical wooden shells 14 and 18 in such a way that the corresponding front sides rest against the vertical wooden shells 14 and 18. Then these horizontal wooden shells 16 and 20 are moved towards the outer edge of the window until the corresponding springs 24 and 28 engage in the corresponding grooves 22 and 26.

For better fixation, the horizontal wooden bowls 16 and 20 are additionally fixed using screws, e.g. stainless steel screws, or holders.

However, it is also possible to design the wooden shells 14, 16, 18 and 20 in such a way that the horizontal wooden shells 16 and 20 are first inserted for the sash frame 10 or the frame 12 and then the vertical wooden rails 14 and 18 are inserted with a certain clamping effect. In this case, the vertical wooden shells 14 and 18 are of course fixed using the screws or holders mentioned above.
