Processes for the production of molded parts have become known in which a wood core is placed in a mold and supported against the mold walls by plastic particles, whereupon the pourable plastic is allowed to flow in after the mold is closed and evacuated and the mold is filled by letting it rest and / or hardened by heating. The German Auslegeschrift 1 119 503 describes a variation of this method, which consists in using, as spacers, hardened droplets of plastic compound which are firmly attached to the wood core and which are made of the same material as the coating compound. After the mold has been evacuated, the plastic that can still be poured surrounds not only the wood mass, but also the plastic mass droplets, partially dissolving them and thus making them a uniform component of the cladding layer.

Window frames can also be produced by such a method, for example by placing several strips of wood of different profile parts put together in such a way that the window frame to be produced except for the one for the plastic »

coat layer provided space is largely filled. When sheathing, the sheathing compound generally penetrates also into the slots between the wooden strips; however, at these points is the plastic layer, which is through the distance between the two wooden strips is determined, generally much less than the layer thickness of the Plastic jacket. So far, however, there have been no reports of any procedures according to which one! Window frames with narrow and narrow recesses, especially with Efuten.

The applicant now has a method for producing such windows, the frames of which are made of plastic-coated Profile parts with a wooden core exist, found in which initially two plastic-coated parts of semi-profile produced, which are chosen so that the desired profile depression results when collapsing and then the two folded profile parts are glued. When defining the profile of the two sub-profiles care must be taken that the profile parting line is along which later the gluing takes place, in the recess or in the groove, preferably in its deepest Part, falls into it.

The subject of this property right are the windows manufactured in this way; These are distinguished from the previously known ones in that the plastic layer, which lies between the wooden cores belonging to the various leilprofilstücke, is significantly thicker than it would be if only flowed into the thin cavity located between two loosely touching plastic parts. It consists, see FIG. 3, of the two plastic layers (1) and (2) produced by the wrapping process and the adhesive layer (3) in between. Even if the same plastic compound is used for gluing as for the sheathing, the three layers (1), (2) and (3) are usually clearly visible when sawing such window frames; if it is not clearly visible at first, it may be possible to make it visible by grinding and polishing the surface. In spite of this, the plastic layers adhere so tightly to one another that in the event of attempts at tearing a break occurs in the mass, but not in the adhesive layers.

The subject of the property right is described for window frames that are horizontal by rotation around their lower Edge to be opened. Such windows can be used, for example, as stable windows or as factory windows.

Figure 1 shows such a built-in stall window in a schematic, perspective illustration. In the masonry (4) the window frame (5) is used for the actual window (6). Window frame (5) and window frame (6) are made of plastic-coated wood. Figures 2 and 4 show sections through the walled-in window with masonry (4) or through the window frame. FIG. 3 shows, on an enlarged scale, a section through a frame part which reveals its construction. The frame part consists made of two essentially identical wooden cores (7), each of which is encased by plastic layers (1) and (2). On the upper edge of the two partial profiles are facing recesses (8) and (9), which when glued together of the two sheathed partial profiles result in the groove (10). In the drawing is the one between the two cladding layers (1) and (2) lying adhesive layer (3) can be seen. The level in which the adhesive layer (3) is located leads through the deepest point of the groove (10).

As little free space as possible remains between the glass pane (11) and the groove (10). If desired, the groove walls can be used also with a plastic pad, such as foam rubber or Foam added to ensure a more effective seal. "

The profile strip shown in FIG. 4 now has a hollow groove (12) in the shape of a semicircle or a circular arc on the lower edge Cross-section with which it sits on the upper part (13) of the window frame (5), which consists of Profile protrudes semicircular. This creates a simple hinge around which the window moves and can be opened. Da windows of the type described here, especially stable windows and windows of industrial buildings, often not fully open to will need; it is sufficient to partially open the window by tilting it inwards. For this purpose is the profile of the frame lower part on the two lower edges upwards and the profile of the window frame below the semicircular Yorsprunges (13) beveled downwards.

In Figures 1 and 2 is a simple device for locking the window at a certain angle of inclination shown within certain limits. The window opening is located on a vertical masonry surface (4)

a horizontal retaining pin (14) and between this and the vertical frame part (16) of the window a flat wedge (17), the tip of which points downwards. By moving the wedge up or down you can get the Make the angle of inclination of the window larger or smaller within certain limits or close the window completely and lock. This wedge is conveniently located in a guide that admittedly moves in a vertical direction allowed, but keeps the wedge permanently parallel to the masonry surface. If such a window is closed by a draft, then the wedge slides down inside the guide and keeps the window closed. This guide will formed here by the plate (15) fastened on the retaining pin (14-), the distance from which to the wall is slightly larger is than the thickness of the wedge (17).

To enable easy insertion or replacement of the window glass, the upper horizontal frame part is included a continuous, vertical slot (18) provided (see. Fig. 4), the horizontal extent of which is approximately is just as large as the distance between the deepest points of the grooves of two opposite, more perpendicular Frame parts. The window glass (11) is now, see Figure 2, pushed into the frame from above and sits down on the groove (10).

In the case of stable and factory windows, it may be desirable to maintain a constant, weak supply of fresh air even when the window is closed. To this end are the dimensions of the groove, see Figure 4, in the lower horizontal frame part (19) selected so that the groove walls do not touch the glass pane. The bottom edge In this case, the glass pane does not sit on the deepest groove part either, but it is increased by something Supports, which are located, for example, at the lower ends of the vertical grooves in the window corners, held. In the embodiment according to FIG. 4, one groove wall has been left out entirely, so that the lower edge of the window pane (11) is exposed on one side and the air flows inside following the arrow (20) even with the window closed of the room can penetrate.

The fastening of such a window in the window opening can be seen from FIGS. 1, 2 and 4; preferably the window frame is anchored to the masonry by a plastic layer (21).
