In general, blinds are used to block light or external gaze from the outside, and there are vertical blinds, venetian blinds, Roman shades, roll screens (roll blinds), etc. depending on the method and structure thereof.

Venetian blinds are generally called blinds, and are blinds that block light by weaving thin and narrow metal plates, wooden plates, and plastic plates at regular intervals. They were first made in the Venetian region of Italy, hence the name Venetian blinds. The blind has a slat that blocks or blocks light while moving up and down or left and right as its component, and has a configuration that allows the inclination of the slat to be adjusted and the whole can be lifted.

In a conventional blind, cloth, wood, or plastic is mainly used. Among them, in the case of wood blinds, there are luxurious solid wood slat wood blinds and wood blinds made of slats that have been transferred to laminated wood made from solid wood residues. The main raw materials are pine, basswood, paulownia, and cypress. trees, etc.

Cypress tree contains a large amount of natural antibacterial substance called phytoncide, which has excellent sterilization effect, and has strong water resistance, so when it comes in contact with water, its unique scent spreads and removes odors.

Cypress trees have the highest phytoncide emission among all tree species. According to a study from Japan, it was announced that phytoncide was released after logging and processing, but not as much as before logging of cypress. Due to this condensed milk, it is used as wood or extracting oil or sap from the cypress tree.

Recently, attempts to use cypress wood as slats for blinds as well as furniture are increasing.

As shown in FIG. 1, the method for manufacturing a blind slat using cypress and paulownia wood according to the present invention includes (a) preparing a thin cypress and paulownia sheet (S1), (b) the above Applying a hot melt adhesive to the front and back surfaces of the paulownia sheet, attaching the thin cypress to the front and back surfaces of the paulownia sheet and pressing to produce a plywood (S2), (c) the plywood for the blind The steps of manufacturing a slat-type plywood by cutting it to a certain size according to the standard of the slat (S3), (d) performing a side finishing treatment of the slat-type plywood (S4), and (e) both sides of the slat-type plywood Forming a hole in the step (S5) to complete the production of the slat is made.

First, a step (S1) of preparing a thin cypress plate 11 and a thin paulownia plate 12 is performed. Cypress and paulownia used in the manufacturing method of the present invention are made of solid wood and are cut in the form of thin plates of a certain thickness. Specifically, the steps of preparing a thin cypress and paulownia plate include ((a-1) cutting the cypress to a thickness of 0.3 mm to form a thin cypress plate (S1-1), (a-2) It consists of a step (S1-2) of cutting paulownia wood to a thickness of 2.5 mm to form a paulownia thin plate First, a thin cypress plate 11 is formed by cutting a solid cypress to a thickness of 0.3 mm. In addition, if it is too thick, it is cut to a thickness of 0.3 mm because the thickness of the slat becomes too thick The thin cypress wood plate 11 is usually chemically treated because it can easily cause bending deformation. However, in the case of chemical treatment, since it may be harmful to the human body due to chemical components, in the present invention, the thin cypress plate 11 that has not been chemically treated is used as it is. It is manufactured by cutting to a thickness of mm. Paulownia wood is known as a wood that does not deform easily, such as easily bent, etc. Accordingly, in the present invention, the thin paulownia wood plate 12 is used as a core material.

Next, as shown in FIG. 2 , a hot melt adhesive 13 is applied to the front and back surfaces of the paulownia thin plate 12 , and the cypress thin plate 11 is attached to the front and back surfaces of the paulownia thin plate 12 . and press to manufacture the plywood 1 (S2). The paulownia thin plate 12 has the advantage that it is not easily deformed due to the characteristics of paulownia wood. Accordingly, paulownia wood is used as the core material. In addition, the cypress thin plate 11 is used for the emission of phytoncide, which is a beneficial substance emitted from the cypress tree. The cypress thin plate 11 uses a thin plate of 0.3 mm, and since it is a thin plate, there is a problem in that bending deformation occurs when chemical treatment is not performed. Accordingly, a thin paulownia wood plate 12 as a core material is used so that it can be used as a slat without chemical treatment. The cypress thin plate 11 and the paulownia thin plate 12 are attached to each other by applying a hot melt adhesive. When attaching, the plywood 1 to which the cypress thin plate 11 and paulownia thin plate 12 are attached to each other is manufactured by pressing with a constant pressure.

Next, the plywood 1 is cut to a predetermined size according to the standard of the blind slat to produce a slat-type plywood (S3). As shown in Fig. 3, the plywood 1 is manufactured to a size capable of producing a plurality of slats 100, and the manufactured plywood 1 is converted to a slat-type plywood 10 of a certain size according to the specifications of the slats. cut A dotted line 13 formed on the plywood 1 is a cut line. A slat-type plywood 10 is formed by cutting it to a predetermined size using a cutter. 4 shows a slat-type plywood 10 formed by cutting with a cutter. The slat-type plywood 10 is formed by attaching a slat-type cypress thin plate 101 and a slat-type paulownia thin plate 102 to each other.

Next, a step (S4) of side finishing of the slat-type plywood 10 is performed. When the slat-type plywood 10 is cut with a cutter, cutting residues and protrusions may remain on the side to be cut. Accordingly, it is necessary to finish the side of the slat-type plywood 10. For the finishing of the slat-type plywood 10, finishing equipment is required. The finishing equipment 2 is formed on both sides of the roller 201 and a pair of rollers 201 that move the slat-type plywood 10 forward while in contact with the front and back surfaces of the slat-type plywood 10, It is composed of a variable sandpaper part 202 that rounds both sides of the slat-type plywood 10 that is moved forward and finishes the side surfaces of the thin paulownia plate 102 and the thin cypress plate 101 . The variable sandpaper part 202 is a shape that can be deformed as the slat-type plywood 10 passes, and is attached to the tubular body 203 into which air is injected, and the tubular body 203 to make the slat-type plywood 10 ) is composed of sandpaper 204 for processing the side surface. As shown in FIGS. 5 and 6 , the slat-type plywood 10 is put into the finishing equipment 20 through the guide 210 . When the slat-type plywood 10 passes through the finishing equipment 20, the tubular body 203 is deformed and the side surface of the slat-type plywood 10 is processed into a rounding form by sandpaper 204, and is also processed with a hot melt adhesive. The glued side parts are finished.

Next, a step (S5) of forming holes on both sides of the slat-type plywood 10 to complete the slat manufacturing is performed. The slat-type plywood 10 is finished with a slat 100 by making a hole for connecting the side and finishing processing the string. The slat 100 is a slat surface 1001 made of a thin cypress wood plate, a slat core 1002 made of a paulownia thin plate, and an adhesive layer 1003 for bonding the slat surface 1001 and the slat core 1002; It is formed on both sides of the slat 100 and consists of a hole 1004 into which the string is inserted. Both sides of the slat 100 form a rounding side 1005 .

Although the above embodiments have been described by way of example, it is obvious to those skilled in the art that the present invention may be embodied in various other forms without departing from the spirit and scope thereof. Accordingly, the above-described embodiments are to be regarded as illustrative rather than restrictive, and all implementations within the scope of the appended claims and their equivalents are intended to be included within the scope of the present invention.
