Description

A utility model relates to the manufacture of special wood products, namely, to the manufacture of structural elements of decorative wood products, and can be used both in the mass production of such products, as well as in the case of their single or small-scale production.

Methods and methods for the manufacture of elements of building structures (timber, board, etc.), consisting of several layers of wood glued together, are widely known. Methods for the manufacture of glued wooden structures are widely known, including drying lumber, cutting into blanks, gluing blanks, cutting glued blanks into shield elements, gluing across the width of a shield, planing layers, forming packages and pressing structures. Known, for example, a glued board made of wood (RU 102205 U1; IPC: В27М 3/06; 02/20/2011), consisting of one or more layers made of blanks glued along the edges, characterized in that the board includes layers glued from blanks trapezoidal section with the formation on one of the surfaces of each layer of longitudinal depressions of a triangular section. The problem solved by this utility model is to reduce the weight of glued panels of increased thickness, improve their consumer properties, as well as reduce the consumption of wood raw materials and glue during their production.

It is also clear that many of the known methods and technologies for the manufacture of building structural elements can be used for the manufacture of decorative wood products.

Known, for example, a method for the manufacture of decorative products (ed. St. SU 636244; IPC: C09J 5/00, В32В 21/14; 05.12.1978), including the successive stages: making blanks; gluing blanks into blocks; holding the blocks until the glue hardens; cleaning the surface of the product.

Known, for example, is a composite material for decorative products and the manufacture of furniture, consisting of alternating glued together wood and acrylic glass plates, subjected to subsequent mechanical processing (DE 202004004750 (U1); IPC: В32В 21/08; В32В 27/30; В44С 5 /00/06.17.2004). This material can be used, for example, in shop furnishing, interior design and the manufacture of furniture for counters, countertops, furniture fronts and furniture sides.

It is also known that color is the property of bodies to evoke a certain visual sensation in accordance with the spectral composition and intensity of the reflected or emitted visible radiation. The main qualities of color are hue, saturation and lightness (Polytechnic Dictionary. Chief editor Academician II Artobolevsky - M., Soviet Encyclopedia, 1976, p. 549). Therefore, when creating decorative products, it is of great importance to use a harmonious color composition in a product - as a set of color relations - taking into account the main characteristics of color. When creating decorative wood products, it is not always possible to achieve this without using means of artificially changing the color of the material used. Meanwhile, there is a unique material - bog oak, which, due to the peculiarities of its formation in the natural environment, has unique properties, both texture and a wide range of possible color shades.

It is known that bog oak is the name for oak trunks extracted from river beds or coastal sediments, where they have lain for several hundred or even thousands of years. The botanical name for bog oak is Quercus pedunculta Ehrh, and the international commercial name is Bog oak. Bog oak wood is a unique material with a wide range of colors, from charcoal with a bluish-violet tint to brownish with contrasting blotches. The color change in oak wood occurs as a result of a chemical reaction between tannins and iron salts dissolved in water. The color shade depends on the concentration and amount of salts in the water and the length of time the wood stays under water. The longer the wood has lain (under water), the darker its color (AA Kosarin, GN Kuryshov. Industrial bog oak - Lesnoy Vestnik, 3/2016, p. 106). Therefore, by the intensity of the color, one can judge the residence time of the oak under water, which can reach several thousand years.

Thus, using the richness of possible color shades inherent in this unique natural material, you can create highly artistic decorative products without the use of any dyes.

The technical result of the claimed utility model is to provide the possibility of forming a variety of options for color composition in decorative wood products.

The closest to the claimed technical solution are the information presented below from two patent documents related, in essence, to the same technical solution.

1) Glued wooden structure (RU 58069 U1; В27М 1/02; 10.11.2006), formed by sequential sawing along the length of a wooden block glued together boards, characterized in that the boards are pre-dried and planed to a parallel state of the glued wide sides and are laid according to the principle in which each adjacent board has an opposite direction of fibers in their cross-section with respect to each other, each of the subsequent boards to be glued should have an opposite direction of fiber growth along the length, each block is formed from boards of the same type according to the principle of sawing boards or with radial or semi-radial or tangential cut.

2) A method of manufacturing glued wooden structures (RU 2339506 С2; IPC: В27М 1/02; 11/27/2008), relating to the manufacture of solid glued panels from a glued wooden block obtained by gluing together sawn boards or lumber of the same type, when not glued the open sides of the board form the main surface of the glued wood block, and the glued wood panels are separated from the main surface of the blocks by sawing, characterized in that the sawing is carried out sequentially, each block is formed from boards of the same type according to the principle of sawing boards or with a radial, or semi-radial, or tangential sawing, the boards are pre-dried to the state required for gluing and punctured to the parallel state of the glued wide sides and laid so that each adjacent board has an opposite direction of fibers in their cross-section with respect to each other, each of the subsequent boards to be glued is laid "crown" to "root", and vice versa, that is, has the opposite direction of growth of fibers along the length.

The disadvantages of this technical solution include, firstly, that each adjacent board in the block has an opposite direction of fibers in their cross section with respect to each other, and secondly, that each of the subsequent boards to be glued should have an opposite direction of growth fibers along the length, as well as uniformity according to the principle of sawing boards, which significantly limits the possibilities for the manufacture of decorative products in this way.

The technical result of the claimed utility model is achieved by the fact that the structural element of a decorative product obtained by sequential sawing along the length of a block from glued together pre-dried boards with wider planed sides, differs in that the boards are made of fossil bog oak wood and are located in block in such a way that each board differs from the neighboring one by the duration of the stay in water of the fossil raw materials from which it is made, before it is extracted from the bedding environment during mining.

Brief Description of Drawings

FIG. 1 shows block 1 of boards 2 made of fossil bog oak glued together with wider sides planed 3.

FIG. 2 shows a block 1 of boards 2 glued together, where the dotted line 4 conventionally shows the plane of sawing block 1 along the length.

FIG. 3 shows a structural element 5.separated from block 1 of boards 2 glued together.

FIG. 4 shows the structural element 5, where the dashed line 6 conventionally shows the plane of sawing the structural element 5 in the transverse direction.

FIG. 5 shows a structural element 7 obtained from a structural element 5 by sawing the latter in the transverse direction.

FIG. 6, as an example, shows the division of block 1 into three structural elements 5.1-5.3, obtained as a result of sawing block 1 along the length.

FIG. 7, as an example, a block 8 of three structural elements 5.1-5.3 glued together is shown.

FIG. 8 shows block 8, where the dashed line 9 conventionally shows the cutting plane of block 8 in the transverse direction.

FIG. 9 shows a structural element 10, separated from block 8 as a result of sawing the latter in the transverse direction.

FIG. 10 shows an example of the manufacture of a block 1 from boards 2 glued together made of fossil bog oak, where each board in the block differs in color from the neighboring one.

FIG. 11 shows an example of the manufacture of structural elements of a decorative product from a fossil bog oak, where: 1 - a block of boards 2 made of fossil bog oak glued together; 5 - a structural element of a decorative item, separated from block 1; 7 - structural elements of a decorative product obtained from a structural element 5 as a result of sawing the latter in the transverse direction.

FIG. 12 shows an example of the manufacture of a structural element 10 of a decorative product from a fossil bog oak, obtained as a result of sawing in the transverse direction of a block of glued together three structural elements (conventionally designated in the drawing as 5a-5c), obtained, in turn, by sawing along the length a block of boards made of fossil bog oak glued together.

To obtain a structural element, it is assembled as shown in FIG. 1, block 1 of glued together pre-dried boards 2 (or lumber of the same type) with wider planed sides 3. Unlike the prototype, in the claimed method, boards 2 are made of fossil bog oak. In this case, the boards 2 are placed in block 1 in such a way that each board differs from the neighboring one by the duration of stay in water of the fossil raw material from which it is made, before it is extracted at the place of extraction. Block 1, as shown in FIG. 2, along the plane indicated in FIG. 2 with a dotted line 4, sawn to length and separated from it, as shown in FIG. 3, structural element 5. In the same way, the remainder of block 1, as shown in FIG. 3 can then be sawed sequentially to form several structural elements, as shown in FIG. 6.

As shown in FIG. 4 and FIG. 5, a structural element 5 by sawing the latter in the transverse direction along the plane conventionally indicated in FIG. 5 with a dotted line 6, if necessary, can be divided into separate fragments (two or more).

Another possible embodiment for the manufacture of structural elements of a decorative wood product is characterized in that several structural elements obtained by sawing a block 1 of boards glued together are glued, as shown in FIG. 7, wide sides between each other, after which the block 8 of several structural elements (5.1-5.3) obtained in this way is sawn, as shown in FIG. 8 and FIG. 9 in the transverse direction along the plane conventionally indicated in FIG. 8 with a dotted line 9, into separate fragments (structural element 10 in Fig. 9).

FIG. 10 to FIG. 12 shows samples of structural elements of decorative products made of fossil bog oak, made in accordance with the claimed utility model.

Since it is known that the color of the fossil bog oak depends on the duration of the stay under water, the adjacent boards 2 in block 1 will differ from each other in color, as shown in Fig. 10 - Fig. 12. Using this feature of bog oak and forming, according to some regularity, a set of color solutions for parts of a decorative product, it is possible, depending on the components of this set of colors and shades of the source material, to create various options for the color composition of the product.

Thus, the claimed utility model significantly expands the possibilities for the formation of various options for the color composition in the manufacture of decorative wood products, which ensures the achievement of the claimed technical result.

Boards 2, as shown in the figures shown, may differ from each other in thickness. At the same time, a person skilled in the art understands that the boards in block 1 do not have to have strictly parallel wider sides, which provides a lot of additional opportunities for realizing the creative idea of the author of a decorative product when manufacturing its structural elements in this way. There is no need to use any means to artificially change the color of the feedstock.
