Description

Designation: door leaf, especially for wooden doors

Description:

The innovation relates to a door leaf, in particular for wooden doors with at least one relief-like elevations and / or Major surface having depressions. They cannot be pre-glued as finished doors or as so-called rinds or come on the market pre-glued.

The manufacture and use of doors with decorative Relief-like structured main surfaces is known. However, such doors or door leaves are produced in a very elaborate way, either using cladding panels that are cut from and / or profile-like elements composed of solid wood are or where carved elements and

Profile elements can be used together with flat elements. As a result of this laborious production For cost reasons, consumers are usually satisfied with the advertising of flat doors or door leaves .

The innovation is based on the task of a door leaf, in particular to create for wooden doors, with the same concise profiled shape compared to the known Solutions are technically simpler and therefore comparatively inexpensive to produce. According to the invention, dss is thereby achieved that the relief-like elevations and / or depressions are pressed into a cladding panel formed with natural wood and attached to a door core. In this way, a natural wood door with a design of the main surfaces can be created very inexpensively, which previously could only be achieved by laboriously carving or joining individual pieces of wood.

It has proven to be particularly advantageous to provide a compression-molded cladding panel because it is compression-molded plate-shaped parts, in particular made of wood, on the one hand, can be produced extremely inexpensively, on the other hand but also with relatively thin starting material such as purees in combination with a solid one Carriers, such as the core of a door leaf, have sufficient strength to be able to use a stronger one Withstand stress. This is particularly true for compression molding a trim panel and gluing it with the core of a door leaf in one operation, with the forces to be applied for the molding process can also be used at least partially at the same time for the production of a particularly secure adhesive connection.

Further details and advantages of the innovation are explained in more detail below with reference to a drawing and / or are the subject of the claims for protection. In the drawing show:

Fig.. 1 is a perspective view of a door leaf according to the invention and

Fig. 2 shows a cross section through the door leaf according to

Fig. 1 along the line II-II in this figure.

As is clear from FIG. 1 of the drawing, the door leaf according to the innovation consists of a core 10, the main surfaces of which are covered with cladding panels 12 and 14. Fig. 2 of the drawing clearly shows that the core 10 consists of rods 11 glued together, which can be made of comparatively inferior wood with branches and other defects, and which are glued to cover or cladding panels 12, which are formed in the usual way can, and which for example consist of strong veneer or can be plywood panels glued with veneer. As can be seen from the 4F \ drawing, according to the innovation, one of the main surfaces of the core "*" is glued to a cladding panel Ik which has a pressed-in relief-like pattern. which are separated from one another and from the edge of the cladding panel by webs 18. Between the webs 18 and the main surface of the core 10 facing them there is a secure adhesive connection which holds the core 10 and the cladding panel 14 together Central field, which is also glued to the core 10. Despite the cavities 16 under the approximately triangular, obliquely inwardly running cassette surfaces, a safe and reliable result is obtained

stable connection between the core 10 and the cladding panel 14, so that the door leaf is in practice is able to withstand the stresses that arise.

From Fig. 1 of the drawing it is clear that a according to the Door leaf designed as an innovation can appear very stylish and expensive, although it is actually comparatively Can be produced cheaply, since compression-molded cladding panels, such as the cladding panel 14, are relatively inexpensive can be produced. This is particularly true in view of the fact that the molds for producing the compression-molded Cladding panels, if necessary after making minor changes, also for the production of ceiling and Wall coverings can be used, so that an economical use of the tools is ensured which leads to the fact that the proportionate tooling costs for the cladding panels of doors is relatively low stay.

From an economic point of view, particularly favorable results are achieved when the cladding panels are compression molded and the gluing of the same to the core 10 of the door leaf takes place in one operation. In In this case the additional operation of gluing can be dispensed with, which in turn leads to leads to a saving in manufacturing costs. In the end ar are due to the fact that under the outwardly protruding parts of the relief structure There are cavities, there are also various options for making the gluing process particularly easy, because, for example, excess adhesive, which is used in cladding panels lying flat, such as the Cladding plate 12, must be removed, can move into the cavities and not only does not interfere there, but at the same time promotes the stability of the door leaf.

While the example shown in FIG. 2 shows the relief-like pattern only on one side, the door can also be provided on the other side with a corresponding plate, which does not have to have the same pattern, but can be adapted to the other room. In the embodiment shown here, the cladding panel formed from several layers of natural wood is partially embossed upwards, so that cavities are formed. Cladding panels can also be used in which the relief-like structure is embossed into the preferably multilayered lining panel only from above, while the lower surface remains smooth as a whole. Which type you choose _Α depends on the respective purpose and pattern. The panels can be sold pre-glued or glued immediately before gluing and also glued onto doors afterwards. However, it is particularly easy to press open and emboss them in one operation when the door is manufactured. The new type of door paneling allows a variety of patterns, whereby wood can be used as an aesthetic means of expression with its warm and appealing structure, without having to choose complex processing methods such as carving or assembling individual profiled parts. A different wood can be used for the surface than for the layers below. Depending on the size of the doors and the type of pattern, the cover sheets show a more or less large surface deformation, whereby the visible surface can consist of a wide variety of woods. Combinations of different types of wood with one another as well as different surface textures are possible at any time. They can be left natural, stained, lacquered, matted or provided with a top coat.
