Description

The invention relates to the furniture industry, in particular to the production of tables, and in particular to the technology for the production of table tops.

Tables with tops made of natural materials such as marble, granite, wood, etc. in addition to a beautiful appearance and wear-resistant coating, they have a number of disadvantages. The main disadvantages are the high price, heavy weight and expensive professional equipment required for their manufacture. For example, the production of marble or granite countertops requires special cutting and polishing equipment. In addition, marble slabs are very heavy, which complicates their transportation and installation.

To solve the identified shortcomings from the prior art, tabletops are known that are made from a base and glass, and externally imitate natural expensive materials.

Known glass top imitating marble (CN 210706367 U, IPC A47B 13/08, publ. 06/09/2020). The tabletop consists of a layer of tempered glass, a layer of baking varnish, a layer of film and a layer of UV varnish, arranged in succession on the top and side surfaces. Between the lacquer layer and the film, a bonding layer is applied to adhere the film, and marble patterns are printed on the film. Lacquer layers are sprayed onto the top surface and sides of the tempered glass layer, then the film is adhered to the top surface and sides of the tempered glass and coated with UV varnish.

The disadvantage of the known countertops lies in the complex manufacturing process and the limited appearance of the countertops.

A tabletop is known (CN 89210943 Y, IPC A47B 13/08, publ. 11/01/1989) made of two glued glass plates, and the texture of marble is painted on the lower plate.

A disadvantage of the known countertop is that it does not realistically mimic the appearance of a marble countertop.

A known method for manufacturing countertops (US 9259083 B1, IPC A47B13/08, publ. 02/16/2016) includes, at the first stage, mixing thermosetting resin, hardener, coloring pigment, filler from 8% to 63% (by weight of thermosetting resin) microspheres, homogeneously dispersed in thermosetting resins, forming the base material, pouring the base material into the table top plate mold, curing the base material, while the base material is opaque, removing the base material from the mold. In the second step, after the base material is cured and removed from the mold, the base material is applied to the base. In the third stage, after the base material is cured and removed from the mold: the formation of a surface layer directly on the base material, including the addition of epoxy, urethane and gel coatings directly to the base material. In this case, the base material, base and surface layer form a single work surface in which, the cured base material resembles a table top made of granite, marble, polished concrete, quartz, glass, laminate, wood, stone and copper.

The disadvantage of the known method is the complex manufacturing process of countertops, requiring a strict ratio of multiple components.

The closest in technical essence to the claimed technical solution is a method for manufacturing a countertop (KR 20200027671 A, IPC A47B 13/08, publ. by means of grooves, and the edge is formed by injection molding in a state where the transparent plate is fixed into the grooves of the base.

The disadvantage of the known method is the technological complexity of manufacturing countertops, requiring special equipment for the formation of edges and material consumption, in addition, the proposed method does not allow manufacturing countertops that repeat the appearance of countertops made from natural expensive materials.

The technical problem to be solved by the proposed method is to eliminate the listed disadvantages of the prototype.

EFFECT: simplification of the manufacturing technology of countertops and reduction of labor costs, weight reduction, improvement of the quality and reliability of countertops with high performance properties and an externally monolithic countertop with a 3D pattern.

The claimed technical result is achieved by the fact that in the method for manufacturing a countertop from a base made of wood-containing material and a plate made of transparent material, according to the invention, edges are cut from a transparent material with a width not less than the thickness of the base, the sides of the edge are sawn at an angle of 45° or 90°, then, a pattern is applied to the plate along with the edge with ultraviolet printing and the resulting pattern is covered with a protective layer, then the edges with the pattern are glued along the perimeter of the base, and the plate with the pattern is glued to its upper part, and the edges and the plate are glued in accordance with the pattern depicted on them, so that the image moved from the plate to the edges of the countertop.

In particular cases of implementation of the invention, the corners of the edges are processed with a cutter. The thickness of the plate is 2-10 mm. The plate is made of glass or clear glass or tempered glass or clear tempered glass or acrylic glass or solid polycarbonate or polyethylene terephthalate (PET). The base thickness is 10-50 mm. The base is made of chipboard (chipboard) or laminated particleboard (LDF) or medium density fibreboard (MDF) or plywood. The edge thickness is 2-10 mm. The edge is made of glass or clear glass or tempered glass or clear tempered glass or acrylic glass or solid polycarbonate or polyethylene terephthalate (PET). The pattern is the texture of natural stone, concrete, wood, abstraction or the Ral palette. The edge and slab are glued to the base using liquid nails or sealant or double-sided tape or glue. A transparent or white film or paint is used as a protective layer of the pattern.

The invention is illustrated by drawings. In FIG. 1 shows a section of the tabletop, Fig. 2a, 2b and 3 show variants of examples of finished worktops.

The table top consists of a wood-based base 1, a board 2 and side edges 3. The board 2 and edges 3 are printed with an image using ultraviolet printing (UV printing). On the bottom of the base there are holes or fasteners are installed for fixing the legs or mounting on floor cabinets.

The method is carried out as follows.

In the manufacture of countertops for its base 1, a sheet of wood-containing material is taken. The base material is chipboard (chipboard) or laminated chipboard (laminated chipboard) or medium density fiberboard (MDF) or plywood sheet. The thickness of the base, depending on the material, the size of the countertop and the required rigidity, is from 10 to 50 mm. After choosing the material for the base, markings are applied on it, along which the extra parts are cut off according to the drawing of the countertop being made. If it is necessary to make the countertop massive by increasing its thickness, inserts in the form of strips of the same material as the base are glued to the underside of the base along its perimeter.

After preparing the base 1 of the tabletop, the top plate 2 is made of a transparent material. As the material of the plate, ordinary glass or clarified glass or tempered glass or tempered clarified glass or acrylic glass or monolithic polycarbonate or polyethylene terephthalate (PET) is used. The thickness of the top plate, depending on the material and size of the tabletop, is from 2 to 10 mm. After choosing the material for the plate, markings are applied on it, along which the extra parts are cut off according to the drawing of the tabletop being made. The area of the top plate 2 must be greater than the area of the base 1, taking into account the thickness of the side edges 3.

Then side edges 3 are made of transparent material, 2-10 mm thick. Ordinary glass or clarified glass or acrylic glass or monolithic polycarbonate or polyethylene terephthalate (PET) is used as the edge material. After choosing the material, markings are made, along which the edges are cut for all sides of the countertop. The width of the edge is not less than the thickness of the base of the countertop. The sides of the edges are sawn at an angle of 45° or 90° for their exact joining in the corners of the tabletop.

An image is applied to the prepared top plate 2 of the tabletop and edges 3 by means of ultraviolet printing. UV printing is applied to the glass and the edge. A white or transparent protective film or paint is applied to the glass and edges with UV printing. The image can be a texture of natural stone, concrete, wood, abstraction, colors or the Ral palette, while the pattern moves from the base plate to the edge, due to which the appearance of a monolithic product is obtained. UV printing is one of the types of printing using UV-curable ink by inkjet printing directly on the material. When exposed to UV radiation of a certain wave, such ink instantly polymerizes and turns into a solid state. Since the ink does not absorb into the material and does not spread over the surface, this allows you to create bright and saturated images.

Edges 3 with a printed image covered with a protective layer are first glued onto the prepared base 1 along its perimeter. After gluing, the corners of the edges are processed with a cutter to dull the corners and make them safe. And then a plate 2 with a printed image covered with a protective layer is glued to the upper part of the base. Edges and plate are glued to base 1 using liquid nails or sealant or double-sided tape or glue. Moreover, the edges 3 and the plate 2 are glued in accordance with the pattern depicted on them, so that the image passes from the plate 2 to the edges 3 of the tabletop. Due to UV printing on the top plate and edges, it is possible to achieve a 3D effect of the applied image on the finished tabletop. When applying an image, for example, in the form of a texture of granite, marble or a slab of wood, it is possible to completely imitate a countertop made of a similar material.

Tabletops produced by this method can have different sizes and appearance.

Example 1 of the manufacture of countertops.

On figa, b countertop size 1100h700 mm sliding with the possibility of increasing with insert 400 mm. 25 mm chipboard base, 4 mm tempered clear glass on top, 4 mm thick acrylic glass edge.

For the manufacture of countertops, a sheet of chipboard with a thickness of 25 mm is taken. A base measuring 546x692 mm is cut out of the sheet using a milling machine - 2 pcs. and insert 396x692 mm. Then they take processed tempered clarified glass 4 mm thick 550x700-2 pcs., 400x700-1 pc. For the manufacture of the edge, acrylic glass 4 mm thick is used. Edges are cut with dimensions of 550x25 mm-4 pcs. and 700x25 mm - 2 pcs., for insert 400x25 mm 2 pcs. Inside, along the edge of the base of the tabletop and the insert on side 700, a 2/28 mm PVC edge is applied, using an edge equipment, and an additive is made for the insert. Edge blanks are sawn at an angle of 45 °. An image of a wood slab is applied to the prepared top plate of the table top and edges using UV printing. Then the drawing is covered with a protective film. On the prepared base along its perimeter, the edges with the printed image are first glued with liquid nails. The corners of the edges are processed with a cutter. Then, with the help of liquid nails, a plate with an image is glued to the upper part. The edges and the slab are glued in accordance with the pattern depicted on them, so that the image passes from the slab to the edges of the countertop and creates a 3D effect. The finished tabletop is shown in Fig. 2a, b.

Example 2 of the manufacture of countertops.

The manufacture of the one-piece tabletop shown in Fig. 3, size 1200x800 mm. They take a chipboard base 22 mm thick, 1192x792 mm in size and glue a false 22 mm bar, 60x1192 mm and 60x792 mm in size, on the underside along its edge. This increases the thickness of the edge, but at the same time the tabletop remains light in weight. Then take acrylic glass 4 mm thick, cut off 2 pcs. 800x44 mm and 2 pcs. 1200x44 mm. Then, treated tempered clarified glass 4 mm thick is taken, the glass after tempering is not processed, 1200x800 mm in size and an acrylic edge, they are simultaneously photoprinted on a UV printer. After drawing the pattern, a protective white film is glued. Then they take the edge with UV printing and glue it on liquid nails to the base of the chipboard, the corners are cut at 90 °. Then the corners are processed with a cutter. At the end, tempered clarified glass is glued on top of the alkali-free silicone sealant. The edges and the slab are glued in accordance with the pattern depicted on them, so that the image passes from the slab to the edges of the countertop and creates a 3D effect.

This method of manufacturing countertops allows you to reduce labor costs and simplify the production technology of countertops. The materials used are inexpensive and readily available. Manufactured countertops have a low weight (compared to natural materials made of stone, marble or slab), have high performance properties, and can also completely imitate countertops made from natural materials.
