Process for the production of period furniture parts or for such certain decorations and device for implementing this process

The invention relates to a method for the industrial large-scale production of period furniture parts and for period furniture certain ornaments with intricate shapes, as well as works of art with a carved appearance.

In one of the known methods of this type cast decorative parts are on the entire period furniture or only placed on parts of the same, whereby these decorative parts usually consist of an inadequate material, which gradually dissolves over time due to cracks or crumbling or peeling or similar phenomena.

In another known method, wood carvings are made on pieces of period furniture or the like by means of bone glue Wooden parts to be decorated are glued on and first given a primer and then a finish. Period furniture parts produced by this method generally have a long service life, but are on the other hand very expensive to produce. In addition, this process is not suitable for the production of period furniture in large series suitable.

Finally, there is another for the production of period furniture parts or for such specific decorations or a carved one Appearance exhibiting works of art, known in which to be provided with ornaments or other decorations Period furniture parts or the art objects to be reproduced are made exclusively from a plastic material are. This process is suitable for industrial large-scale production of period furniture parts or reproduced art objects, but has the disadvantage that the objects produced by this process if only because of their, compared to what is actually necessary Material, far too light weight, stand out as cheap imitation. In addition, when molding such Parts of casting burrs cannot be avoided and these casting burrs cannot be completely removed afterwards, like this that with such pieces the nature of the manufacturing process and the material is particularly evident.

Based on this prior art, the present invention is based on the object of providing a method for Manufacture of period furniture parts or similar works of art, in which the various disadvantages the known method can be avoided and which makes the production extremely durable, the impression handmade pieces of awakening furniture or works of art, enables. Another purpose of the invention is

stands in it, the wooden parts of the period furniture or works of art in an effective way with a protection against rot or insects such as termites.

This object is achieved according to the invention by a method in which the decorations or complicated shapes Formed from period furniture or works of art made of plastic material and using a mold from a Material with elastic properties, either in the simple or in the injection molding process on a natural wood core or a piece of furniture made of natural wood, in particular a piece of furniture, can be poured on. That to carry out the procedure plastic material used, is in terms of its Weight of the weight of the intended type of wood or the type of wood of the natural wood core, adjusted accordingly and continuously colored in the mass, so that the finished part in terms of its weight at least approximately with a hand-made original piece matches and wear or damage occurring over long periods of use the decorative parts cannot cause the wood paint to peel off.

According to another feature of the invention, a painted version can be used for certain period furniture parts or works of art are provided, in particular projections and particularly raised parts of the decorations with a mount to be painted.

Another feature of the method according to the invention is that when demolding the finished furniture parts or art objects the inner shape made of a material with elastic properties is slit in the longitudinal direction will.

The device according to the invention for performing the above The method comprises a casting mold made of a material with elastic, received in a rigid shell Properties in which a wooden core or a cut of a piece of furniture to be provided with decorations is arranged. The one that receives the actual casting mold

The shell is in particular made of wood, but it can also consist of another suitable material.

Period furniture parts or works of art produced in the method according to the invention differ with regard to their Appearance and their handiness or their weight, not or only insignificantly of originals carved out of wood, so that in the case of period furniture in use, the large-scale production is no longer noticeable.

The method according to the invention is shown in the following description of the example using one shown in the drawing Embodiment of the device for performing the method, with regard to the individual method steps described in detail. In the drawing shows the

Figure 1 a raw, with carving-like decorations provided wooden part, in particular a chair or armchair;

FIG. 2 shows a section through a device according to the invention to carry out the method according to the invention;

FIG. 3 shows one using the method according to the invention Chair or armchair foot with carving-like decorations, as well as two cross-sections through this chair or armchair base in different heights and different scale ratios.

As can be seen in particular from the illustration in FIG. 2, the device for carrying out the invention comprises Method, a casting mold 2 made of an elastic material and one that receives and supports it Shell 1 made of a solid material, for example wood. Of course, the shell 1 can also be made of ir-

consist of a different material. On the outside, the casting mold 2 has a conical design, which makes demolding easier. The shell 1 is expediently divided in the longitudinal direction, so that it unites when demolding; axis parallel to its longitudinal axis unfolded worrk-n k;? nn. The actual casting mold 2, which consists of a material with elastic properties, is slit open in the longitudinal direction for the purpose of nasty demolding of the finished part, thereby avoiding damage to the period furniture part produced by the method according to the invention. In the mold 2 of the Stuhlfußrohling '{> is arranged centrally. After the core formed by the blank 3 is inserted into dio mold 2 that needed to form the decoration of plastic material 4 is either simply by casting or by injection molding in the cavity between the mold 2 and the blank '- introduced). The plastic material 4- the blank 2 completely envelops and at the same time impregnates the wood of the blank 5 against rot. In addition, due to the reaction of the plastic material M- in the casting mold 2, the wood of the blank is somewhat changed, which increases its stability and strength. The amount of plastic material to be cast, which is expediently adjusted to the weight of the intended type of wood in terms of its weight and measured according to the volume of the casting mold 2.

The plastic material to be used is also colored in the mass, see above. that the cast part also after wear and tear in long-term use or after occasional damage it still looks like a hand-made one Original part retains. On the other hand, foils or particularly raised parts of the cast or injection-molded Decoration can be painted with a frame, through which these parts get a similar appearance, as by hand Original pieces carved from wood.

The method according to the invention enables production

of period furniture or period furniture parts or art objects of all kinds in large series and permitted with exception strong resinous types, the use of any type of wood.
