[Modes for carrying out the invention]

[0019] Embodiments will be described below with reference to the drawings. The features and technical effects of the embodiments will be understood from the following detailed description and drawings. However, the scope of the present invention is not limited to the embodiments disclosed below. The scope of the present invention is not limited to the examples in the drawings, as the drawings are provided for illustrative purposes only.

[0020] <1. Plate> Figure 1 is a perspective view showing the upper part of the window area as seen from inside Room 1 of a building such as a house. The building is made of wood, reinforced concrete, or steel-reinforced concrete. Room 1 has a wall 3L in the first direction. Room 1 has a wall 3R opposite to wall 3L in the second direction. Room 1 has a window 2 in the third direction, and a wall opposite to window 2 in the fourth direction. The first, second, third, and fourth directions are, for example, east, west, south, and north, respectively. Room 1 has a ceiling 5 as its top surface, and a floor opposite to ceiling 5 as its bottom surface.

[0021] The underside of ceiling 5 is the ceiling surface. This ceiling surface is the surface to which plate 10 is attached. The surfaces of walls 3L and 3R are wall surfaces, and these wall surfaces are second surfaces to which plate 10 is supported, and these wall surfaces are perpendicular to the ceiling surface.

[0022] Plate 10 is a decorative or fascia board in the shape of a strip. Plate 10 is attached to the ceiling 5 near the window 2 on the inside of room 1. Plate 10 hangs from the ceiling 5 perpendicular to the ceiling 5, parallel to the indoor surface of window 2. Plate 10 extends horizontally along window 2 from wall 3L to wall 3R. A curtain rail is provided in the ceiling 5 between plate 10 and window 2. Plate 10 forms part of a curtain box, and the internal space of the curtain box opens downwards. Since the internal space is partitioned by plate 10, plate 10 can also be called a partition plate.

[0023] Plate 10 has thickness in the front-to-back direction, length in the up-to-down direction, and width in the left-to-right direction. Plate 10 is a long material that is longer in the left-to-right direction. That is, the width of plate 10 is greater than the length of plate 10, and the length of plate 10 is greater than the thickness of plate 10. Hereafter, the front-to-back direction will also be called the thickness direction, the up-to-down direction will also be called the length direction, and the left-to-right direction will also be called the width direction. When plate 10 is installed on the ceiling 5, the width and length directions are parallel to the indoor surface of window 2, and the thickness direction is perpendicular to the indoor surface of window 2. When plate 10 is installed on the ceiling 5, the width and thickness directions are horizontal, and the length direction is vertical.

[0024] Plate 10 will be described in detail with reference to Figures 2 to 15. Note that the rear view is the same as the front view in Figure 4, the left side view is the same as the right side view in Figure 5, the rear view is the same as the front view in Figure 12, and the left side view is the same as the left side view in Figure 13. The plate 10 comprises a plate body 20, a support rail 40, side rails 50L, 50R, and hanging pieces 51, 52.

[0025] The plate body 20 comprises a core 21, a first decorative panel 22, a second decorative panel 23, and a third decorative panel 24.

[0026] The core 21 has a strip-like outer shape. The core 21 is a honeycomb structure, with numerous cavities formed within it, which penetrate the core 21 in the thickness direction. These cavities are also called cells. The material of the honeycomb structure is paper, resin, ceramic, or a composite of two or more of these. The apparent specific gravity of the core 21 is lower than that of wood, and the core 21 is lighter than dense wood of the same volume as the core 21. The specific gravity of the material of the core 21 may be lower than that of wood. For example, the core 21 is a corrugated sheet stack made by stacking corrugated sheets in the vertical or horizontal direction. If the corrugated sheet stack is made of paper, it is also called a paper honeycomb. The core 21 may also be a foam material such as urethane foam, polyethylene foam, or polystyrene foam. Foam materials are also called foams.

[0027] The first decorative panel 22 and the second decorative panel 23 are formed in the shape of thin strips. The first decorative panel 22 and the second decorative panel 23 are installed parallel to each other. The first decorative panel 22 is attached to the front surface of the core 21, and the second decorative panel 23 is attached to the rear surface of the core 21, with the core 21 sandwiched between the first decorative panel 22 and the second decorative panel 23. The first decorative panel 22 and the second decorative panel 23 have a thickness thinner than the thickness of the core 21.

[0028] The first decorative panel 22 and the second decorative panel 23 have a vertical width that is longer than the vertical width of the core 21. The lower ends of the first decorative panel 22 and the second decorative panel 23 are aligned with the lower end of the core 21. The first decorative panel 22 and the second decorative panel 23 protrude upward from the upper end of the core 21. In other words, the first decorative panel 22 and the second decorative panel 23 have protruding portions 26 and 27 that protrude upward from the upper end of the core 21, and the fitting groove 25 is formed between the protruding portions 26 and 27. Therefore, the plate body 20 has a fitting groove 25 recessed from its upper end surface on its upper end surface.

[0029] The first decorative panel 22 and the second decorative panel 23 have a width longer than the width of the core 21. The first decorative panel 22 and the second decorative panel 23 protrude to the left from the left end of the core 21. In other words, the first decorative panel 22 and the second decorative panel 23 have protruding portions 28L and 29L that protrude to the left from the left end of the core 21, and the fitting groove 30L is formed between the protruding portions 28L and 29L. Therefore, the plate body 20 has a recessed fitting groove 30L on its left side end surface. The upper part of the fitting groove 30L is provided continuously with the left part of the fitting groove 25.

[0030] The first decorative panel 22 and the second decorative panel 23 protrude to the right from the right end of the core 21. In other words, the first decorative panel 22 and the second decorative panel 23 have protruding portions 28R and 29R that extend to the right from the right end of the core 21, and the fitting groove 30R is formed between the protruding portions 28R and 29R. Therefore, the plate body 20 has a recessed fitting groove 30R on its right side end face. The upper part of the fitting groove 25 is provided continuously with the right part of the fitting groove 30R.

[0031] The third decorative panel 24 is formed in the shape of a thin strip. The third decorative panel 24 is attached to the lower surface of the core 21. The third decorative panel 24 and the first decorative panel 22 form the corner between the lower surface and the front surface of the plate body 20. The third decorative panel 24 and the second decorative panel 23 form the corner between the lower surface and the rear surface of the plate body 20. The third decorative panel 24 protrudes from the left end of the core 21, and the lower end of the fitting groove 30L is blocked by the third decorative panel 24. The left end of the third decorative panel 24 is aligned with the left ends of the first decorative panel 22 and the second decorative panel 23. The third decorative panel 24 protrudes from the right end of the core 21, and the lower end of the fitting groove 30R is blocked by the third decorative panel 24. The right end of the third decorative panel 24 is aligned with the right ends of the first decorative panel 22 and the second decorative panel 23.

[0032] The decorative panels 22, 23, and 24 are made of wood-based boards such as fiberboard or particleboard. The fiberboard may be insulation board, medium-density fiberboard (MDF), or hard board. The decorative panels 22, 23, and 24 may be plywood instead of wood-based board. The decorative panels 22, 23, and 24 may be wood-based boards or plywood with a decorative sheet, such as a polyolefin sheet, attached to them. The decorative sheet has a wood grain pattern printed on it. The decorative sheet of the decorative panels 22, 23, and 24 may be provided continuously without interruption at the boundary between the first decorative panel 22 and the third decorative panel 24, and at the boundary between the second decorative panel 23 and the third decorative panel 24.

[0033] The inner edges of the pair of sides of the fitting groove 25 are tapered, and the thickness of the protruding portions 26 and 27 of the decorative panels 22 and 23 gradually decreases towards the front. By cutting out the inner sides of the pair of sides of the fitting groove 25, grooves 31 and 32 are formed on the pair of sides of the fitting groove 25, respectively. In other words, grooves 31 and 32 are formed on the protruding portions 26 and 27 of the decorative panels 22 and 23, respectively. The grooves 31 and 32 face each other with the fitting groove 25 between them. Groove 31 extends laterally from the left end to the right end of the first decorative panel 22. The left and right ends of groove 31 open laterally at the left and right ends of the first decorative panel 22. The cross-sectional shape of groove 31 is rectangular. Groove 32 extends laterally from the left end to the right end of the second decorative panel 23. The left and right ends of groove 31 open laterally at the left and right ends of the second decorative panel 23. The cross-sectional shape of groove 32 is rectangular.

[0034] The support rail 40 is provided in the shape of a square bar. The support rail 40 may be made of wood, wood fiberboard, resin, or metal. If the support rail 40 is made of wood, it may be made of solid wood, laminated wood, or engineered wood.

[0035] The support rail 40 is attached to the ceiling 5 near the window 2 on the inside of room 1. The support rail 40 is fixed to the ceiling 5 by driving multiple fasteners 49, such as screws or nails, into the support rail 40 and the ceiling 5 from below. The support rail 40 extends in the width direction, with one side of the support rail 40 facing outwards towards room 1 and opposite the indoor surface of window 2, and the other side of the support rail 40 facing inwards towards room 1.

[0036] Both ends of the support rail 40 are spaced apart from the walls 3L and 3R, with spacer 60L positioned between the end of the support rail 40 and wall 3L, and spacer 60R positioned between the end of the support rail 40 and wall 3R. Spacer 60L is sandwiched between the ceiling 5 and the upper end of the side rail 50L, and spacer 60R is sandwiched between the ceiling 5 and the upper end of the side rail 50R.

[0037] Grooves 41 and 42 are formed on both sides of the support rail 40 by cutting out both sides of the support rail 40. Groove 41 extends in the width direction from the left end to the right end of the support rail 40. The left and right ends of groove 41 open in the width direction at the left and right ends of the support rail 40. The cross-sectional shape of groove 41 is rectangular. Groove 42 extends in the width direction from the left end to the right end of the support rail 40. The left and right ends of groove 42 open in the width direction at the left and right ends of the support rail 40. The cross-sectional shape of groove 42 is rectangular.

[0038] The top surface of the plate body 20 faces the ceiling 5, and the support rail 40 is fitted into the fitting groove 25 of the plate body 20. The upper end of the plate body 20, that is, the upper ends of the decorative panels 22 and 23, abuts against the ceiling 5. The spacers 60L and 60R are located inside the fitting groove 25 of the plate body 20. Even if there is a gap between the upper ends of the decorative panels 22 and 23 and the ceiling 5, the spacers 60L and 60R make the gap less noticeable.

[0039] The grooves 41 and 42 of the support rail 40 face the grooves 31 and 32 of the plate body 20, respectively. The hook piece 51 is fitted into the groove 31 of the plate body 20 and the groove 41 of the support rail 40, and the hook piece 51 is hooked onto the grooves 31 and 41. In addition to this hooking, the hook piece 51 may be bonded to the inner surface of the grooves 31 and 41 with adhesive. The hook piece 52 is fitted into the groove 32 of the plate body 20 and the groove 42 of the support rail 40, and the hook piece 52 is hooked onto the grooves 32 and 42. In addition to this hooking, the hook piece 52 may be bonded to the inner surface of the grooves 32 and 42 with adhesive. The hooking of the hook piece 51 into the grooves 31 and 41 and the hooking of the hook piece 52 into the grooves 32 and 42 provide restraint for the support rail 40 with respect to the fitting groove 25. In addition to these hookings, the support rail 40 may be bonded to the inner surface of the fitting groove 25 with adhesive.

[0040] The shape of the hook piece 51 in a cross-section perpendicular to the width direction is rectangular, and the combined shape of the grooves 31 and 41 in that cross-section is rectangular. Therefore, the hook piece 51 is less likely to come off the grooves 31 and 41. Similarly, the cross-sectional shape of the hook piece 52 is rectangular, and the combined cross-sectional shape of the grooves 32 and 42 is rectangular, so the hook piece 52 is less likely to come off the grooves 32 and 42.

[0041] The hanging piece 51 may be provided along the entire length of the grooves 31 and 41, from the left end to the right end of the support rail 40 and the plate body 20. The hanging piece 51 may be divided into multiple pieces, and the fragments of the hanging piece 51 may be arranged within the grooves 31 and 41 at intervals in the lateral direction.

[0042] The hanging piece 52 may be provided along the entire length of the grooves 32 and 42, from the left end to the right end of the support rail 40 and the plate body 20. The hanging piece 51 may be divided into multiple pieces, and the fragments of the hanging piece 51 may be arranged in the grooves 32 and 42 with spacing between them in the lateral direction.

[0043] The hanging pieces 51 and 52 may be made of wood, wood-based board, resin, or metal.

[0044] The hook piece 51 may be integrally formed with the protruding portion 26 of the plate body 20, and the hook piece 51 may be provided in a convex shape on the side surface of the fitting groove 25. Alternatively, the hook piece 51 may be integrally formed with the receiving rail 40, and the hook piece 51 may be provided in a convex shape on the side surface of the receiving rail 40.

[0045] The hook piece 52 may be integrally formed with the protruding portion 27 of the plate body 20, and the hook piece 52 may be provided in a convex shape on the side surface of the fitting groove 25. Alternatively, the hook piece 52 may be integrally formed with the receiving rail 40, and the hook piece 52 may be provided in a convex shape on the side surface of the receiving rail 40.

[0046] The side rails 50L and 50R are provided in the shape of square bars. The side rails 50L and 50R may be made of wood, wood fiberboard, resin, or metal. If the side rails 50L and 50R are made of wood, they may be made of solid wood, laminated wood, or engineered wood.

[0047] The side rail 50L is attached to the wall 3L near the window 2 on the inside of room 1. The side rail 50L is fixed to the wall 3L by driving multiple fasteners 59L, such as screws or nails, into the side rail 50L and the wall 3L from the side of the side rail 50L.

Similarly, secure the side rail 50R to wall 3R with multiple fasteners 59R and insert the spacer 60R between the upper end of the side rail 50R and the ceiling 5. The process of securing the side rails 50L and 50R to walls 3L and 3R may be performed before or after the process of securing the support rail 40 to the ceiling 5.

[0054] After installing the support bars 40 and side bars 50L and 50R as described above, apply adhesive to the pair of inner sides of the fitting grooves 25 of the plate body 20. Specifically, apply the adhesive along the upper and lower edges of the grooves 31 and 32. Note that adhesive may not be used.

[0055] With the second decorative panel 23 of the plate body 20 facing the window 2, the top surface of the plate body 20 is directed toward the upper support rail 40, and the plate body 20 is lifted from below the side rails 50L, 50R. This allows the side rails 50L, 50R to be inserted into the fitting grooves 30L, 30R of the plate body 20 from below. By further lifting the plate body 20 while guiding it with the side rails 50L, 50R, the support rail 40 is fitted into the fitting groove 25 of the plate body 20, and the adhesive is spread by the sides of the support rail 40 and the hook pieces 51, 52. Because the inner edges of the pair of sides of the fitting groove 25 are tapered, the support rail 40 can be easily fitted into the support rail 40. When the upper end of the plate body 20 is brought against the ceiling 5, the hook pieces 51, 52 are fitted into the grooves 31, 32. This fixes the plate body 20 to the support rail 40.

[0056] In the above description, the hanging pieces 51 and 52 were fitted into the grooves 41 and 42 of the receiving rail 40, respectively, and then the receiving rail 40 was fitted into the fitting groove 25 of the plate body 20, thereby fitting the hanging pieces 51 and 52 into the grooves 31 and 32 of the plate body 20, respectively. Alternatively, the hanging pieces 51 and 52 may be fitted into the grooves 31 and 32 of the plate body 20, respectively, and then the receiving rail 40 may be fitted into the fitting groove 25 of the plate body 20, thereby fitting the hanging pieces 51 and 52 into the grooves 41 and 42 of the receiving rail 40, respectively.

[0057] <3. Examples of plate usage> Furthermore, since the curtain rail is installed on the ceiling 5 between the plate 10 and the window 2, as described above, the plate 10 is used as a partition, decorative panel, or fascia board. However, the installation location of the plate 10 is not limited to near the window 2.

[0058] For example, plate 10 may be attached to the ceiling above the alcove in a Japanese-style room. Plate 10 used in this way is called a decorative board or a decorative panel. For example, the plate 10 may be attached to the ceiling above the cupboard so that the gap between the cupboard and the ceiling is filled by the plate 10. A plate 10 used in this way is called a decorative plate, a fascia, or a filler. For example, plate 10 may be attached to the underside of the tabletop between the legs of the table. Plate 10 used in this way is called a decorative plate or apron.

[0059] Figure 16 is a ceiling plan. As shown in Figure 16, multiple plates 10 may be attached to the ceiling 5A parallel to each other. In this case, a lowered ceiling 5B, which is one step lower than the ceiling 5A, may be installed around the periphery of the ceiling 5A. Plates 10 used in this way are called decorative boards, ceiling decorations, or skirting boards.

[0060] <4. Example of change (1)> Multiple plate bodies 20 may be arranged in the lateral direction from side rail 50L to side rail 50R, and multiple support rails 40 may be arranged in the lateral direction from side rail 50L to side rail 50R. In this case, as shown in Figure 17, the first decorative panel 22, second decorative panel 23, and third decorative panel 24 of the plate body 20 are abutted against the first decorative panel 22, second decorative panel 23, and third decorative panel 24 of the adjacent plate body 20, respectively. A rectangular connecting member 70 is inserted into the fitting groove 30R of the plate body 20 and the fitting groove 30L of the adjacent plate body 20, so that the connecting member 70 makes the gap at the joint of the adjacent plate body 20 less noticeable. A spacer 71 is sandwiched between the upper end of the connecting member 70 and the ceiling 5, and is also positioned between adjacent support rails 40.

[0061] <5. Example of change (2)> As shown in Figure 18, the two plate bodies 20 may be attached to the ceiling 5 at a right angle. In this case, the first decorative panel 22 of one plate body 20 is abutted perpendicularly against the first decorative panel 22 of the adjacent plate body 20, the second decorative panel 23 of one plate body 20 is abutted perpendicularly against the second decorative panel 23 of the adjacent plate body 20, and the third decorative panel 24 of one plate body 20 is abutted perpendicularly against the third decorative panel 24 of the adjacent plate body 20 in a miter joint. An L-shaped connecting member 76 is inserted into the fitting groove 30R of one plate body 20 and the fitting groove 30L of the adjacent plate body 20, so that the connecting member 76 makes the gap at the joint between the adjacent plate bodies 20 less noticeable. Spacers 77 and 78 are sandwiched between the upper end of the connecting member 76 and the ceiling 5.

[0062] <6. Example of change (3)> In the above embodiment, the support rail 40 is attached to a horizontal ceiling surface. Alternatively, the support rail 40 may be attached in a horizontal position to a vertical surface, for example, the surface of a wall. In this case, the thickness direction is vertical, and the length and width directions are horizontal. The side rails 50L and 50R are attached in a horizontal position to a pair of opposing vertical second surfaces. The pair of second surfaces are perpendicular to the surface to which the support rail 40 is attached. For example, the second surface is the surface of a wall perpendicular to the wall to which the support rail 40 is attached. The plate 10 attached in this position may be used as a shelf.

[0063] <7. Variation (4)> In the above embodiment, the support rail 40 is attached to a horizontal ceiling surface. Alternatively, the support rail 40 may be attached in a vertical position to a vertical surface, for example, the surface of a wall. In this case, the thickness direction and height direction are horizontal, and the width direction is vertical. The side rails 50L and 50R are attached in a horizontal position to a pair of opposing horizontal second surfaces. The pair of second surfaces are perpendicular to the surface to which the support rail 40 is attached. For example, the second surface to which the side rail 50L is attached is the ceiling surface, and the second surface to which the side rail 50R is attached is the floor surface. The plate 10 attached in this position may be used as a partition plate or a side plate.

[0064] <8. Variation (5)> In the above embodiment, the cross-sectional shape of the combination of grooves 31 and 41 is rectangular, and the cross-sectional shape of the hook piece 51 is rectangular. In contrast, as shown in Figure 19, the inner surface of groove 41 may be a cylindrical concave surface 41a, and the hook piece 51 may have a cylindrical convex surface 51a on its side that fits into the cylindrical concave surface 41a. Similarly, the inner surface of groove 42 may be a cylindrical concave surface 42a, and the hook piece 52 may have a cylindrical convex surface 52a that fits into the cylindrical concave surface 42a. In such cases, the hook pieces 51 and 52 can easily come out of grooves 41 and 42, and the plate body 20 can easily be removed from the support rail 40. Also, when attaching the plate body 20 to the support rail 40, the cylindrical convex surfaces 51a and 52a come into contact with the support rail 40 and are guided by the support rail 40, making it easier for the protruding portions 26 and 27 of the first decorative plate 22 and the second decorative plate 23 to open in a direction away from each other. Therefore, the plate body 20 can be easily attached to the support rail 40.

[0065] <9. Variation (6)> In the above embodiment, the cross-sectional shape of the combination of grooves 31 and 41 is rectangular, and the cross-sectional shape of the hook piece 51 is rectangular. In contrast, as shown in Figure 20, the hook piece 51 may have a tapered surface 51b on the upper part of its side surface. Similarly, the hook piece 52 may have a tapered surface 52b on the upper part of its side surface. The tapered surfaces 51b and 52b contribute to making it easier to attach the plate body 20 to the support rail 40. Furthermore, grooves 41 and 42 may each have inclined surfaces 41b and 42b on their inner surfaces that are in surface contact with the tapered surfaces 51b and 52b, respectively.

[0066] <10. Variation (7)> In the above embodiment, the cross-sectional shape of the combination of grooves 31 and 41 is rectangular, and the cross-sectional shape of the hook piece 51 is rectangular. As shown in Figure 21, the hook piece 51 may have a tapered surface 51c at the bottom of its side surface, a tapered surface 51d at the top of its side surface, and the groove 41 may have an inclined surface 41c at the bottom of its inner surface, and an inclined surface 41d at the bottom of its inner surface. When the hook piece 51 is fitted into the groove 41, the tapered surfaces 51c and 51d make surface contact with the inclined surfaces 41c and 41d, respectively. Similarly, the hook piece 52 may have a tapered surface 52c at the bottom of its side surface, a tapered surface 52d at the top of its side surface, the groove 42 may have an inclined surface 42c at the bottom of its inner surface, and an inclined surface 42d at the bottom of its inner surface, and the tapered surfaces 52c and 52d may make surface contact with the inclined surfaces 42c and 42d, respectively. The tapered surfaces 51c and 52c contribute to making it easier to remove the plate body 20 from the support rail 40. The tapered surfaces 51d and 52d contribute to making it easier to attach the plate body 20 to the support rail 40.

[0067] <11. Summary> (1) The support rail 40 is attached to a surface such as the underside of the ceiling 5, the support rail 40 is fitted into the fitting groove 25 of the plate body 20, the hook piece 51 is hooked into the groove 41 of the support rail 40 and the groove 31 of the plate body 20, and the hook piece 52 is hooked into the groove 42 of the support rail 40 and the groove 32 of the plate body 20, thereby fixing the plate body 20 to the surface. Fixing the plate body 20 using the support rail 40 and the hook pieces 51 and 52 is stronger and less prone to deterioration over time compared to fixing with adhesive.

[0068] (2) Since the side rails 50L and 50R are fitted into the fitting grooves 30L and 30R of the plate body 20, the side ends of the plate body 20 are supported by the walls 3L and 3R, and the fixing of the plate body 20 is stable.

[0069] (3) Because the core 21 is a honeycomb structure or foam material, the plate body 20 is lightweight and the plate body 20 is less likely to come off the surface.

[0070] (4) The energy used from the production to the disposal of wood and paper materials is less than the energy used from the production to the disposal of metal or concrete materials. Therefore, if wood or paper is used as the raw material for the core 21, decorative panels 22-24, support rails 40, side rails 50L, 50R, and hanging pieces 52, then plate 10 contributes to the realization of a decarbonized society by promoting carbon neutrality, which results in virtually zero carbon dioxide emissions, and to the achievement of the Sustainable Development Goals (SDGs).

[0071] (5) The embodiments disclosed herein are for illustrative purposes only and are not intended to limit the scope of the invention. The scope of the invention should be interpreted by the terms of the claims. [Explanation of symbols]
