Both the pair of decorative panels and the edge band are fixed to the core layer with an adhesive. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-74264 Summary of the Invention [Problem to be solved by the invention]

[0004] When the conventional decorative panels described above are used as desk tops, etc., there is a risk that the surface may become damaged or dirty, resulting in a poor usability. Conventionally, when such problems become serious, the decorative panel itself has been replaced with a new one, but this has led to a problem of increasing the amount of waste, which places a heavy burden on the environment.

[0005] SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a board member for furniture that is environmentally friendly while easily maintaining a good usability, and a method for manufacturing the same. [Means for solving the problem]

The periphery of the main body is covered with an edge band, the edge band has a protruding portion protruding from the outer surface of the main body, and the surface material is arranged so that a gap is formed at least partially between the surface material and the protruding portion. This is achieved by means of a board member for furniture.

[0007] In this furniture board member, it is preferable that the through-hole is covered by an edge of the surface material.

[0008] before Preferably, the protruding portion has a curved portion formed on its inner periphery that curves inward so that the protruding height gradually decreases.

[0009] The object of the present invention is also achieved by a method for manufacturing a board member for furniture, which comprises a first step of covering the peripheries of a pair of panel panels arranged opposite each other with a gap therebetween with an edge band and then injecting a core material between the pair of panel panels to form a board-shaped main body, a second step of forming through holes in the formed main body, and a third step of covering the outer surface of the main body with a surface material, wherein the third step involves adhering the surface material to the main body with a weakly adhesive so as to cover one open end of the through hole. [Effects of the Invention]

[0010] According to the present invention, it is possible to provide a board member for furniture that is easy to maintain a good feeling of use while also being environmentally friendly, and a method for manufacturing the same. [Brief explanation of the drawings]

[Figure 7] FIG. 7 is a view showing a state in which a part of the surface material shown in FIG. 6 has been peeled off. DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a plan view of a board member for furniture according to one embodiment of the present invention. The board member for furniture according to this embodiment shows an example of its use as a top plate for a desk, table, etc. FIG. 2 is a cross-sectional view of a main part of the top plate 1 shown in FIG. 1. As shown in FIGS. 1 and 2, the top plate 1 includes a plate-shaped main body 10 and a surface material 20 that covers the outer surface of the main body 10, and is formed into a rectangular shape as a whole in a plan view. The top plate 1 is preferably flat as in this embodiment, but may also be partially or entirely curved.

[0013] The main body 10 includes a core material 15 between a pair of face plates 12 and 13, and the entire periphery of the pair of face plates 12 and 13 and the core material 15 is covered with an edge band 14.

[0014] The pair of face plates 12, 13 are thin (for example, about 3 mm) flat plate-like members, and can be made of synthetic resin such as ABS resin or polystyrene resin, or wood material.

[0015] The edge band 14 is a flexible tape-like member, and is formed from, for example, various elastomers or thermoplastic resins such as polyvinyl chloride. Both side edge portions in the width direction of the edge band 14 are bent in the same direction, and these bent portions engage with the outsides of the pair of face plates 12, 13, respectively, thereby forming protruding portions 14a, 14b that protrude toward the outer surfaces of the pair of face plates 12, 13. On the inner periphery of the protruding portions 14a, 14b, curved portions 14c, 14d are formed, respectively, that are curved in an arc shape so that the protruding height gradually decreases inward.

[0016] The core material 15 has a thickness (for example, about 20 mm) greater than that of the pair of face plates 12, 13, and is made of foamed resin such as foamed polystyrene or foamed ABS.

[0017] A mounting member 16 is fixed by adhesive or the like to the inner surface of the face plate 13, which becomes the lower surface when in use. The mounting member 16 is a plate-like member made of, for example, ABS resin or particle board, and a support frame (not shown) having legs can be fixed to the face plate 13 by screwing in tapping screws, wood screws, or the like. The thickness of the mounting member 16 is, for example, about 5 mm.

[0018] The surface material 20 is a thin (e.g., about 1 mm) rectangular flat plate-like member, and can be made of various materials, such as melamine decorative board or polyester plywood. The surface material 20 is adhered to the outer surface of the top panel 12 via a weak adhesive layer made of a weak adhesive. The weak adhesive layer reliably maintains the adhesion of the surface material 20 to the main body 10 when the table top 1 is in use, while having a moderate adhesive strength that allows the surface material 20 to be peeled off from the main body 10 when peeling off; for example, an acrylic adhesive, a silicone adhesive, a rubber adhesive, a urethane adhesive, etc. can be used.

[0019] In the tabletop 1 having the above-described configuration, through-holes 17 are formed in the corners of the main body 10, penetrating in the thickness direction and opening into the pair of face plates 12, 13. One open end of the through-hole 17, which is the upper surface side when in use, is covered by the edge of the surface material 20, and the other open end, which is the lower surface side when in use, is open.

[0020] The tabletop 1 having the above-described configuration can be manufactured as follows. First, a pair of face plates 12, 13 are arranged facing each other with a gap between them, and the peripheries of the pair of face plates 12, 13 are covered with an edge band 14 to form a closed space between the pair of face plates 12, 13. Next, a foaming resin material is injected into the closed space through an injection port (not shown) formed in the edge band 14, and the injection port is closed and the material is heated and cured to form the main body 10 (first step). The pair of face plates 12, 13 and the edge band 14 can be used as a foaming mold when forming the core material 15 from the foaming resin material, making it easy to form the main body 10. Next, a through hole 17 is formed at a predetermined position in the main body 10 (second step). After this, a surface material 20 is adhered to the outer surface of the main body 10 with a weak adhesive so as to cover the upper open end of the through hole 17 (third step). In this manner, the tabletop 1 can be easily manufactured. The manufacturing method of the tabletop 1 is not necessarily limited to the above method, and for example, the tabletop 1 can also be formed by bonding a pair of face plates 12, 13 to both sides of a plate-shaped core material 15, forming a through hole 17, and removably covering the through hole 17 with a surface material 20.

[0021] In the tabletop 1 of this embodiment, the surface material 20 is bonded to the main body 10 with a mild adhesive. Therefore, if the surface material 20 becomes significantly scratched or dirty, deteriorating the usability, the surface material 20 can be easily peeled off from the main body 10 using the through-holes 17, as described below. Therefore, the surface material 20 can be replaced with a new one, maintaining a good usability. Furthermore, because the main body 10 can be continuously used, it is only necessary to dispose of the original surface material 20, and there is no need to discard the entire tabletop 1. This reduces waste and reduces the environmental impact. The replaced surface material 20 may be of the same type, but variations can also be enjoyed by changing the color, texture, etc.

[0022] When peeling the surface material 20, as shown in FIG. 3, a rod-shaped pressing member 100 is inserted into the through-hole 17 from below and pressed against the surface material 20, thereby partially pushing up and peeling the surface material 20. Then, starting from the peeled portion of the surface material 20, the entire surface material 20 is peeled off from the main body 10 by pulling up as shown by the arrow in FIG. 4. The through-hole 17 is preferably formed at a position where the edge of the surface material 20 can be pushed up, which allows for quick and easy replacement of the surface material 20. In this invention, the edge of the surface material 20 refers to the frame-shaped portion around the periphery of the surface material 20 from which the outer periphery of the surface material 20 can be peeled off by pressing with the pressing member 100. The width of this frame-shaped portion is, for example, 10 cm.

[0023] Furthermore, in this embodiment, through hole 17 is formed in only one location, but the number of through holes 17 is not particularly limited, and for example, multiple through holes 17 may be formed in locations corresponding to the four corners of surface material 20, multiple locations along one side of surface material 20, locations symmetrical to each other about the center of surface material 20, etc. The opening shape of through hole 17 is circular in this embodiment, but it may also be elliptical or polygonal, or may be formed in a special irregular shape so that only a dedicated pressing member 100 can be inserted through through hole 17.

[0024] A gap may be formed between the edge band 14 and the surface material 20 to make it easier to peel the surface material 20 when replacing it. In the table top 1 shown in FIG. 5, the surface material 20 is formed slightly smaller than the outer surface of the face plate 12 on the upper side surrounded by the protruding portion 14a of the edge band 14, and when the surface material 20 is adhered to the face plate 12, a small gap S is formed between the protruding portion 14a and the surface material 20. The size of the gap S may be large enough to allow a spatula-shaped or blade-shaped scraper used to peel off the surface material 20 to be inserted, but if it is too large, dirt and the like will easily accumulate in the gap, so it is, for example, about 1 to 5 mm.

[0025] Fig. 6 is an enlarged view of a main portion showing the vicinity of the gap S in Fig. 5. As shown in Fig. 6, it is preferable that the protruding height H1 of the protruding portion 14a of the edge band 14, when the outer surface of the main body 10 (the outer surface of the face plate 12) is used as a reference, is higher than the height H2 to the upper surface of the surface material 20 adhered via the weak adhesive layer 21. This allows the peripheral edge of the surface material 20 to be protected by the protruding portion 14a, preventing the corners of the surface material 20 from being exposed and suppressing unexpected peeling, etc.

[0026] 7, when peeling the surface material 20, the tip 111 of the scraper 110 is inserted between the face plate 12 and the surface material 20 via the gap S, and the scraper 110 is rotated as shown by the arrow with the abutment point C with the protrusion 14 as a fulcrum, thereby peeling off the edge 20a of the surface material 20 using the principle of leverage, and then the peeled edge 20a is lifted up to peel off the entire surface material 20. Because a curved portion 14c is formed on the inner periphery of the protrusion 14a, the scraper 110 can be moved smoothly along the curved portion 14c, facilitating the insertion of the tip 111 and the movement of the fulcrum C, making it easy to peel off the edge of the surface material 20.

[0027] The gap S may be formed along the entire periphery of the surface material 20 between the protrusion 14a and the surface material 20, or may be formed along only a portion of the periphery of the surface material 20. The surface material 20 shown in FIG. 5 has its bottom and right edges positioned along the protrusion 14a so as not to create gaps, forming gaps S between the top and left edges of the surface material 20 and the protrusion 14a, and through-holes 17 are formed near the gaps S. This configuration allows the surface material 20 to be reliably peeled from a single location by combining the insertion of a pressing member 100 into the through-holes 17 and the insertion of a scraper 110 into the gaps S. Alternatively, the through-holes 17 may be formed at locations separated from the gaps S, allowing the surface material 20 to be peeled from multiple locations. If the surface material 20 can be peeled by forming the gaps S alone, it is not necessary to form the through-holes 17.

[0028] The furniture board member of the present invention can be suitably used as a tabletop as described above, but is not limited to this use and can also be used, for example, as a shelf board for a storage shelf or as a room divider (partition), etc. The furniture board member of this embodiment is configured so that one outer surface of the main body 10 is covered with the surface material 20, but both surfaces of the main body 10 may be covered with the surface material 20.
