Description

  The present invention relates to a lightweight full-scale board that can be used on a desk and has a function that is the same size as a regular board and is light and easy to handle.

  Traditionally, Go is often performed on a tatami mat in a Japanese-style room. Therefore, a regular board is made of a thick wooden board with four legs that are heavy and have a high board surface. In recent years, it has become a life of chairs and desks. In Go clubs, heavy boards with legs with thick boards are avoided, and only boards without legs are often used.

  Also, in the practice of Go clubs such as residents' associations, a board made of a folding wooden board with a thickness of about 3 to 5 cm is often used, and a regular board with legs is not used. The reason for this is that regular boards are difficult to carry and there is no suitable alternative to wooden boards. In other words, the conventional board (a) is heavy and difficult to carry, requires a lot of labor for installation and tidying work, (b) the feel of wood does not come out, the struck stone is easily displaced, and (c) stable (D) When a wooden board is made of a synthetic resin, the weight is increased, and (e) the strength of the board surface is low, so that it cannot be used for a long time.

  Another similar prior art is disclosed in Patent Document 1, for example. In this prior art, a stable board with improved stability is proposed in which a single sheet is attached to the back of two board halves and the board halves can be folded together. ing.

  The sheet body adhered to the back surface of the two half boards is made of a synthetic resin sheet such as vinyl chloride, polyethylene, or polypropylene having a thickness of about 0.3 mm to 1 mm.

  The above-described other prior art board is thin and light and has a low flatness of the board, so it is easy to carry, but when placed on a flat mounting surface such as a desk, There is a problem similar to that of the first prior art described above that the board is easily slipped with respect to the surface of the desk on which the board is placed, and the board moves easily. Further, the above-mentioned prior art board has a problem that it cannot be used for a long time because the surface of the board is not water-resistant and is easily soiled. In addition, the above-mentioned prior art grid has a grid grid formed on the surface of each half of the grid, so that there is a problem that the feel of wood is not obtained, the meteorite is slippery, and the stability when placing the meteorite is poor. .

  The object of the present invention is to solve the problems of the first prior art and the other prior art described above, have good water resistance, and stably mount without moving on a flat mounting surface such as a desk. It can be used on a desk and can be used on a desk, and it is light and easy to handle. It is to provide a full-scale board.

FIG. 1 is a partial enlarged cross-sectional view showing a configuration of a lightweight authentic board 1 of a reference example of the present invention, FIG. 2 is a perspective view showing the entire appearance of the lightweight authentic board 1, and FIG. 4 is an exploded perspective view showing the relationship between the sheet 4 and the back sheet 6, FIG. 5 is a bottom view of the lightweight full-scale board 1, and FIG. FIG. Note that FIG. 1 shows a lightweight full-scale board 1 enlarged in the thickness direction for easy illustration.

  The lightweight full-scale board 1 of this embodiment can be advantageously implemented when storing a plurality of sheets collectively in an individual's home, meeting place, school, hospital, nursing home, nursing facility, or the like. The lightweight full-scale board 1 is the same as a regular board in plan view, L1 × L2 shown in FIG. 2 is a rectangle of about 455 mm × about 410 mm, and the thickness D1 is about 4 mm to 7 mm. A substrate 2 made of building material, a topsheet 4 that is flexible and wrapped around the substrate 2 by an adhesive 3a, and an adhesive 5a from the back side to the substrate 2 wrapped around the topsheet 4 And a plurality of belt-like anti-slip materials 8A, 8B, 8C, and 8D (hereinafter collectively referred to as anti-slip materials) attached to the substrate 2 to which the back sheet 6 is attached by a double-sided adhesive tape 7 from the back side. (Sometimes referred to as “slip prevention material 8”). The adhesives 3a and 5a form the adhesive layers 3 and 5 by being cured.

  The substrate 2 is made of a new building material. New building materials include Medium Density Fiber Board (abbreviated as MDF), a type of molded board (fiber board) made of wood fiber, The Slim (registered trademark) manufactured by Dow Chemical Co., Ltd. A pladan sheet that is a hollow structure plate made of polypropylene by extrusion molding, a polyplate made of hard urethane, polyester, or the like, Decopane (registered trademark) that is a foamed polystyrene board, or a veneer plate can be used.

  Among the above, as the new building material constituting the substrate 2, it is preferable to use a medium density fiberboard. The reason is that the medium density fiberboard is smaller in the constituent elements (segments) than the particle board or oriented strand board (OSB) made of the same wood chip material, and not only the surface but also the lip part is smooth, This is because it is light and highly workable like wood, has few warps and dry cracks peculiar to wood, is homogeneous and extremely inexpensive.

  The adhesive 3a for adhering the top sheet 4 to the substrate 2 and the adhesive 5a for adhering the back sheet 5 to the substrate 2 are so-called aqueous adhesives mainly composed of a vinyl acetate resin, for example. Woodworking adhesive is used.

The upper edge portion 2a and the lower edge portion 2b of the four sides of the substrate 2 form, for example, a ¼ circle having a radius of curvature R of about 1 to 2 mm and extend along each side, and curved outwardly and convexly. It is chamfered by a face.

  The top sheet 4 is formed by printing a regular grid of grids made of water-resistant paper. Further, the top sheet 4 is bent from the side surface to the back surface of the substrate 2 and is attached to the substrate 2 in a wrapped manner.

  As the water-resistant paper constituting the top sheet 4, stone paper or the like can be used. Stone paper is made of inorganic mineral powder extracted from stone without using wood chips or kenaf as a raw material. As such a stone paper, Keeplus (registered trademark) RPD series manufactured by TBM Co., Ltd. can be used.

  Moreover, the surface sheet 4 is connected to the rectangular base portion 4a attached to the one substrate surface 9 of the substrate 2 by the adhesive 3a and the four sides of the base portion 4a, respectively, and the thickness direction of the substrate 2 (vertical direction in FIG. 1).

It has the back surface folding | returning parts 4c1-4c4 each affixed.

  As shown in the developed view of FIG. 3, the top sheet 4 is a single sheet in which the base 4 a, the side folded portions 4 b 1 to 4 b 4, and the back folded portions 4 c 1 to 4 c 4 are integrally formed. The sheet is folded as shown in FIG.

  On the base part 4a of the top sheet 4, a grid pattern of a regular grid is printed. That is, on the base portion 4a of the top sheet 4, a printing layer 14 that forms a 19 × 19 grid pattern that reproduces the regular grid surface is formed by printing. Here, the dimensions of the outermost grid of the grid grid are the same as those of a regular grid, L3 shown in FIG. 2 is about 425 mm, and L4 is about 390 mm. Also, the dimensions from the peripheral edge of the substrate 2 to the outermost grid of the grid grid are the same as those of a regular grid, L5 shown in FIG. 2 is about 10 mm, and L6 is 15 mm. In addition, the size of one grid surrounded by the grid is the same as a regular grid, and L7 × L8 shown in FIG. 2 is about 23.6 mm × about 21.7 mm.

  In addition, as a printing method for forming a grid pattern of a regular grid on the base portion 4a of the top sheet 4, a surface of the regular grid is photographed, a printing plate making based on the photographed photo is produced, and printing is performed. Is called.

  Further, a transparent coating agent such as a lacquer paint is applied to the base portion 4a of the top sheet 4 on the printing layer 14 constituting the grid lattice, and the coating agent is cured to form the coating layer 13. Such a covering layer 13 prevents damage to the base 4a due to contact of the meteorite and the like, and prevents damage to the printed layer 14 that is printed on the base 4a and constitutes the grid grid.

  In addition, the printing layer 14 which comprises the grid grid formed on the base 4a of the surface sheet 4 is not limited to being formed by printing, and may be formed by color copying.

  The back sheet 6 attached to the back surface 11 of the substrate 2 is made of water-resistant paper that is the same material as the top sheet 4. Further, on the back surface 11 of the substrate 2, strip-shaped anti-slip materials 8 </ b> A, 8 </ b> B, 8 </ b> C, and 8 </ b> D having a width dimension of about 10 mm are attached on the back sheet 6.

The anti-slip materials 8A, 8B, and 8C are attached to the center and both sides of the double-sided adhesive tape 7 with an interval in the width direction that is the left-right direction in FIG. Further, the anti-slip material 8 </ b> D is pasted by the double-sided pressure-sensitive adhesive tape 7 over the entire circumference along the outer peripheral edge of the substrate 2 with an interval of about 5 mm from the peripheral edge of the substrate 2. The double-sided pressure-sensitive adhesive tape 7 has a base layer 7a made of a synthetic resin film having flexibility, and pressure-sensitive adhesive layers 7b and 7c formed on both surfaces of the base layer 7a. The adhesive layers 7b and 7c are made of, for example, an acrylic adhesive.

  As shown in FIGS. 1 and 6, the anti-slip material 8 includes a base layer 8a made of a flexible synthetic resin sheet or paper, and an adhesive made of an adhesive laminated on one surface of the base layer 8a. The layer 8b and the surface layer 8c which consists of foaming synthetic resins, such as polyester, laminated | stacked on the one surface of the adhesion layer 8b are included. The adhesive layer 8b is made of, for example, a rubber adhesive.

  Since the surface layer 8c of the anti-slip material 8 is formed in a concavo-convex shape as shown in FIG. 6, when the surface layer 8c of such an anti-slip material 8 comes into contact with a flat surface such as a desk, an external force is prevented. Can generate a large static frictional force and suppress the movement of the lightweight full-scale board 1.

  As described above, the lightweight full-scale board 1 of the present embodiment is configured such that the top sheet 4 is attached to the substrate surface 9 of the substrate 2 of the new building material. The surface sheet 4 to be affixed to the substrate 2 is made of water-resistant paper and is printed with a regular grid surface. Since the substrate 2 is made of a new building material, the weight can be reduced, and when a meteorite is placed on the lightweight full-scale board 1, the feel of wood can be obtained, and it can be moved on a flat surface such as a desk. It is possible to place it stably without doing.

  Further, the surface sheet 4 to be affixed to the substrate 2 is made of water-resistant paper and printed with a regular grid of grids, so that it has good water resistance and is difficult to get dirty, and can be used for a long time. it can.

  Therefore, the lightweight authentic board 1 of this embodiment has a function that is usable on a desk and has the same size as a regular board, is light and easy to handle, and realizes a board that can enjoy full-scale go. be able to.

  Moreover, in the light-weight full-scale board 1 of this embodiment, the surface sheet 4 stuck on the board | substrate 2 is bent over the back surface 11 from the side surface of the board | substrate 2, and is stuck on the board | substrate 2. A back sheet 6 made of water-resistant paper, which is the same material as the top sheet 4, is attached to the back surface 11 of the substrate 2. Thereby, for example, even when the lightweight authentic board 1 is stood and stored, deformation such as warpage can be prevented and the top sheet 4 and the back sheet 6 are peeled off from the substrate. And it can prevent that a corner | angular part is damaged.

  Moreover, in the lightweight full-scale board 1 of this embodiment, the anti-slip material 8 is stuck on the back sheet 6 on the back surface 11 of the substrate 2. As a result, the lightweight full-scale board 1 can be stably placed without moving on a flat placing surface such as a desk.
