In addition, the pair of end members 5 has a mirror-symmetrical structure.

As shown in FIGS. 5 to 7, the main body member 4 is elongated and has a U-shaped cross section. Note that the term "longitudinal shape" refers to a shape in which the length in one direction (horizontal direction in the illustrated example) is sufficiently longer than the length in a direction perpendicular to the one direction (horizontal direction). called the longitudinal direction. Although the main body member 4 is not particularly limited, it is preferably made of metal such as aluminum, steel, stainless steel, etc. In this embodiment, it is made of aluminum.

The main body member 4 is mainly composed of a flat plate portion 40 having a rectangular shape in plan view and a pair of projecting plate portions 41 . The flat plate portions 40 form upper and lower end faces of the decorative member 1 . Each projecting plate portion 41 is provided over the entire length slightly inside both side edges along the longitudinal direction of the flat plate portion 40 . As a result, when the pair of projecting plate portions 41 are inserted from the upper and lower ends of the tubular member 2 , the flat plate portions 40 abut against the upper and lower ends of the tubular member 2 , so that the main body member 4 is pushed into the upper and lower ends of the tubular member 2 .

As shown in FIGS. 8 to 14, the end member 5 is mainly composed of an end surface portion 50 having a rectangular shape in plan view, a pair of side surface portions 51, and a fitting portion 52. As shown in FIGS.

The end surface portion 50 forms upper and lower end surfaces of the decorative member 1 together with the flat plate portion 40 of the main body member 4 . The end surface portion 50 is provided with a communication hole 53 passing through the end surface portion 50 . The communication hole 53 communicates the inside and the outside of the tubular member 2, and although details will be described later, when the inside of the tubular member 2 is filled with resin as the core material 6, the air inside the tubular member 2 is removed. It plays a role as an air vent to extract. Although the installation position of the communication hole 53 on the end face portion 50 is not particularly limited, it is preferable that the communication hole 53 is provided near the end of the end face portion 50 on the outer side in the longitudinal direction.

Each side surface portion 51 is provided so as to extend in the longitudinal direction slightly inside both side edges along the longitudinal direction of the end surface portion 50 . One end in the longitudinal direction of each side portion 51 protrudes from the end of the end face portion 50 in the same direction, and the other end in the longitudinal direction of each side portion 51 stops inside the end of the end face portion 50 in the same direction. As a result, when the pair of side surface portions 51 are inserted from the upper and lower ends of the tubular member 2 , the end surface portions 50 abut against the upper and lower ends of the tubular member 2 , so that the edge members 5 are inserted into the upper and lower ends of the tubular member 2 . The edge member 5 does not drop into the tubular member 2 even if it is fitted into the tubular member 2.例文帳に追加Each side surface portion 51 has a shape in which a portion on the main body member 4 side and the end surface portion 50 side is notched, and a fitting portion 52 is provided in the notched portion. In each side surface portion 51, a portion of the edge opposite to the end surface portion 50 on the side of the main body member 4 is inclined low toward the main body member 4, and the height thereof gradually decreases.

The end member 5 is attached to the body member 4 by sliding the fitting portions 52 into the body member 4 from the left and right ends of the body member 4 . At this time, the end surface portion 50 continues flush with the flat plate portion 40 of the main body member 4 , and each side surface portion 51 continues flush with the corresponding projecting plate portion 41 of the main body member 4 . Engagement grooves 54 extending in the longitudinal direction are provided on both side surfaces of the fitting portion 52 . The engagement grooves 54 engage with the engagement projections 42 provided on the projecting plate portions 41 of the body member 4 to fix the end member 5 to the body member 4 .

In addition, the end member 5 has a plate-like rib 55 provided between the pair of side surface portions 51 . One or a plurality of ribs 55 are provided between the pair of side portions 51 and are provided at right angles to each side portion 51 to reinforce each side portion 51 .

The thicknesses of the end surface portion 50, the side surface portion 51, the ribs 55, and the like of the end member 5 are not particularly limited, and are set to appropriate thicknesses in consideration of the strength of the end member 5 and the like.

The core material 6 is filled inside the tubular member 2 in order to impart strength, heat insulation, sound insulation, etc. to the decorative board base material 1 . The material of the core material 6 is not particularly limited, and may be polyolefin resin such as polyethylene resin or polypropylene resin, thermoplastic resin such as polyvinyl chloride resin, acrylic resin, ABS resin, styrene resin, urethane resin, or the like. Although thermosetting resins such as phenolic resins and epoxy resins can be used, it is preferable to use thermoplastic resins for the reason that processing conditions can be easily controlled. In order to reduce the weight and improve the heat insulation and soundproofing properties, it is preferable to mix a foaming agent with the resin and form a porous foamed resin. In this embodiment, foamed urethane resin is used as the core material 6 . The foamed urethane resin has excellent adhesion to the metallic tubular member 2 , thereby improving the strength of the decorative board base material 1 and preventing the decorative board 1 from warping.

The decorative plate base material 1 may have decorative sheets (not shown) on the surfaces (four front, rear, left, and right surfaces) of the tubular member 2 . As the decorative sheet, for example, a paper-based or resin-based decorative sheet or the like can be used, which is attached to the surface of the cylindrical member 2 with an adhesive, an adhesive, or the like. As the paper-based decorative sheet, for example, general paper, reinforced paper between papers, impregnated paper, and a polyethylene sheet (commonly called polysand paper) in which thin paper is pasted on the front and back sides thereof, and printed on can be used. As the resin-based decorative sheet, polyolefin, polyester, vinyl chloride, or acrylic resin can be used singly or in multiple layers. Among them, considering the environment, a decorative sheet with multiple layers of polyolefin and a surface protective layer containing an ionizing radiation-curable resin on the outermost surface is preferable. Most preferably it is a mold resin.

The decorative sheet may be directly attached to the surface of the tubular member 2. However, when the decorative plate base material 1 is used as a wall panel such as a partition or screen, the tubular member 2 may be attached to the surface of the tubular member 2. A magnetic plate, a magnet sheet, or the like may be fixed to the surface as necessary, and a decorative sheet may be attached to the surface of the magnetic plate, the magnet sheet, or the like. Accordingly, articles and advertisements can be posted on the decorative board base material 1 by using a magnet or the like.

Next, a method for manufacturing the above-described decorative sheet base material 1 of the present embodiment will be described. First, an adhesive is applied to the back surface of the decorative sheet to form an adhesive layer. The decorative sheet with the adhesive layer formed thereon is attached to the two metal plates 20 and 21 forming the cylindrical member 2, respectively. Depending on the use of the decorative plate base material 1, the decorative sheet having the adhesive layer formed thereon is attached to the magnetic sheet, and the magnetic sheet with the decorative sheet attached thereto is attached to the two metal plates 20 and 21, respectively. .

Next, of the two metal plates 20 and 21 to which the decorative sheets are attached, one metal plate 20 is bent in a U-shape to form the front or back and the left and right side surfaces, and the left and right sides of the metal plate 20 are formed. is bent into a predetermined shape to form the engaging portion 22 . The other metal plate 21 forms an engaging portion 23 by bending left and right ends into predetermined shapes. Then, the two metal plates 20 and 21 are connected in a tubular shape by engaging the engaging portions 22 and 23 at the corresponding ends of the two metal plates 20 and 21 with each other so that the tubular member 2 is formed. shape.

Next, the hollow member 4 is cut to an appropriate length according to the length of the tubular member 2 , and end members 5 are attached to the left and right ends of the body member 4 to form the edge member 3 . Then, the edge member 3 is fitted to the tubular member 2 by fitting the upper and lower ends of the tubular member 2, respectively.

Finally, an injection hole (not shown) for injecting resin is formed in the body member 4 (flat plate portion 40) of the edge member 3 fitted to one end of the tubular member 2, and the tubular member 2 is The communication hole 53 of the end member 5 (end face portion 50) of the edge member 3 fitted to the other end of the edge member 3 is closed with a seal or the like. Then, a resin, preferably a thermoplastic resin, more preferably a foamed urethane resin is injected through the injection hole to fill the inside of the cylindrical member 2 with the resin. At the time of filling the resin, the air inside the cylindrical member 2 escapes from the communication hole 53 of the end member 5 (end face portion 50 ) of the edge member 3 fitted to one end of the cylindrical member 2 . When the inside of the tubular member 2 is sufficiently filled with the resin, the injection of the resin is stopped. Injection of the resin can be stopped when the resin reaches the communication hole 53 . Then, the injection hole and the communication hole 53 functioning as an air vent are closed with a seal or the like. An edge tape (not shown) may be attached to the entire exposed surface of the edge member 3 . Thereby, the decorative board base material 1 is manufactured.

As described above, according to the present embodiment, since the edge member 3 is composed of the main body member 4 and the pair of end members 5, even if the dimensions of the cylindrical member 2 are different due to the purpose of the decorative plate base material 1, the difference in dimensions, etc. By cutting the main body member 4 to a length corresponding to the length of the tubular member 2, the edge member 3 can be made to match the dimensions of the tubular member 2. It can be snugly fitted to the edge. As described above, in this embodiment, since the dimension of the edge member 3 can be adjusted according to the dimension of the cylindrical member 2, the edge member 3 with different dimensions corresponding to the cylindrical member 2 of various dimensions can be provided. There is no need to prepare a plurality of types of edge members 3, and it is possible to prevent the inventory of the edge members 3 from increasing, and to improve the productivity of the edge members 3 and reduce the manufacturing cost.

Further, according to the present embodiment, the tubular member 2 is formed by connecting two metal plates 20 and 21 facing each other in a tubular shape. It is easier to form a cylindrical shape (favorable formability) by connecting two metal plates facing each other into a cylindrical shape than by forming a single metal plate into a cylindrical shape. It has excellent effects in terms of excellent shape stability at the time of application and the ability to increase the size of the cylindrical member 2 .

Further, according to the present embodiment, since the end member 5 of the edge member 3 is made of resin, the end member 5 having a complicated shape can be formed by injection molding or the like compared to the case where the end member 5 is made of metal. It can be formed easily, and productivity can be improved. On the other hand, if the main body member 4 of the edge member 3 is made of resin, the strength of the central main body member 4 is low, so that the strength of the edge member 3 is lowered. The edge member 3 may expand due to temperature changes, which may cause a dimensional error. and the dimensional stability of the edge member 3 can be improved. Furthermore, since the body member 4 of the edge member 3 is made of metal, the cutting workability of the body member 4 can be improved.

Further, according to this embodiment, since the ribs 55 are provided between the side portions 51 of the end member 5 on both sides of the edge member 3, the strength of the end member 5 is increased even if it is made of resin. . Therefore, the strength of the edge member 3 can be improved as a whole.

Further, according to this embodiment, the main body member 4 of the edge member 3 and each end member 5 are fixed by engagement by the engagement projections 42 and the engagement grooves 54, so that the edge member 3 can be easily shaped. can be done.

In addition, according to the present embodiment, in both side surface portions 51 of each end member 5 of the edge member 3 , a part of the edge opposite to the end surface portion 50 on the side of the main body member 4 is inclined low toward the main body member 4 . Therefore, when the resin is injected from the injection hole of the main body member 4, the resin is guided toward each end member 5 along the above-described inclined edges of the side surfaces 51 of each end member 5. As shown in FIG. Therefore, the resin can be spread over the inside of each end member 5, and the resin can be filled all over the tubular member 2 from one end to the other in the longitudinal direction.
