[0007] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. A decorative panel fixing structure 1 of this embodiment is configured by fixing a decorative panel 10 to a kitchen unit 100 of a kitchen. The kitchen unit 100 has a countertop 101 on which cooking equipment such as a sink 102 and a stove (not shown) are arranged, and the countertop 101, sink 102, and stove are supported by a cabinet 104. The kitchen unit 100 has a substantially rectangular parallelepiped shape, and a decorative panel fixing structure 1 is provided along the longitudinal side. The decorative panel fixing structure 1 includes a decorative panel 10, a box portion 2, cross bars 3, fixing brackets 4 (see FIG. 2 ), and a gap retaining member 5.

[0008] In this specification, the horizontal direction refers to a direction extending generally parallel to the installation surface of kitchen unit 100. The top-bottom direction of kitchen unit 100 is referred to as the vertical direction, and the direction perpendicular to the vertical and horizontal directions is referred to as the depth direction.

[0009] The box portion 2 has a thin, approximately rectangular parallelepiped shape with one side open toward the outside of the cabinet 104. The box portion 2 is provided in the kitchen unit 100 to which the decorative panel 10 is attached. The box portion 2 has an opening 20, a back portion 21, an upper surface portion 22, a lower surface portion 23, and a pair of side surfaces 24.

[0010] The opening 20 is formed by opening the outer surface of the cabinet 104 to which the decorative panel 10 of the box part 2 is attached. The opening 20 is closed when the decorative panel 10 is attached.

[0011] The rear surface portion 21 is disposed on the surface opposite the decorative panel 10 to be attached, and is a substantially rectangular, planar portion facing the interior of the cabinet 104. The rear surface portion 21 has a rear plate portion 211 on which a substantially rectangular plate material is partially disposed, and a rear opening portion 212 that opens to the interior of the cabinet 104. The upper surface portion 22 is a narrow, rectangular plate material that extends from the upper edge of the rear surface portion 21 toward the outside of the cabinet 104. The upper surface portion 22 is disposed along the lower surface of the top plate 101. The lower surface portion 23 is disposed opposite the upper surface portion 22, and is a narrow, rectangular plate material that extends from the lower edge of the rear surface portion 21 toward the outside of the cabinet 104. The lower surface portion 23 is in contact with the installation surface.

[0012] The pair of side surface portions 24 connect the ends of the upper surface portion 22 and the lower surface portion 23 and extend in the vertical direction. The pair of side surface portions 24 are narrow rectangular plate members that extend from a pair of opposing side edges of the back surface portion 21 toward the decorative panel 10 side.

[0013] The decorative panel 10 is a substantially rectangular board and is disposed on the side of the cabinet 104. A surface 10a of the decorative panel 10 forms the side of the cabinet 104. The side on which the decorative panel 10 is disposed is, for example, disposed on the rear side (the side on which the user is not positioned when in use) of a face-to-face kitchen unit 100. The decorative panel 10 is connected to the box portion 2 by a hinge 6 so as to be openable and closable. The hinge 6 is disposed on one lateral side of the opening 20, with a gap between them above and below. The hinge 6 rotatably connects one side of the pair of side portions 24 to one side of the inner surface of the decorative panel 10.

[0014] As shown in FIG. 2, the cross beam 3 is a thin, flat member extending in the horizontal direction of the opening 20. The cross beam 3 is arranged opposite the decorative panel 10 and connects the ends of the pair of side surface portions 24 on the decorative panel 10 side. The direction in which the cross beam 3 extends from one of the pair of side surface portions 24 to the other is the longitudinal direction, and the short side direction is arranged along the vertical direction of the opening 20. The thickness direction of the cross beam 3, which is perpendicular to the longitudinal and short side directions, extends along the depth direction of the kitchen unit 100. As shown in FIG. 3, the cross beam 3 is arranged with a gap between it and the back surface portion 21.

[0015] The fixing bracket 4 is a bracket that fixes the decorative panel 10 to the cross bar 3 to prevent rattle between the decorative panel 10 and the box section 2. As shown in FIG. 2, the fixing bracket 4 is arranged on the back surface 10b of the decorative panel 10, on the side opposite to the one lateral side to which the hinge 6 is attached. The fixing bracket 4 has a first bracket 41 fixed to the decorative panel 10 side and a second bracket 42 fixed to the cross bar 3 side.

[0016] 4A, first metal fitting 41 is formed by bending a substantially rectangular metal plate. First metal fitting 41 has a fixing surface portion 411, a plate surface portion 412, a guide portion 413, and a through groove 414.

[0017] The fixing surface portion 411 is a substantially rectangular plate-like portion. Two screw holes are formed in the fixing surface portion 411 with a gap between them in the longitudinal direction. The fixing surface portion 411 is fixed to the rear surface 10b of the decorative board 10 with screws.

[0018] The plate surface portion 412 is bent from the fixing surface portion 411 in a generally L-shape in side view and extends toward the opening 20. The plate surface portion 412 has a generally rectangular flat surface and is arranged so that its longitudinal direction is the longitudinal direction of the fixing surface portion 411 and its lateral direction extends toward the opening 20. The plate surface portion 412 is arranged on the upper surface 3a of the cross rail 3 when the decorative panel 10 is in a state where it is closing the opening 20 of the box portion 2.

[0019] The through groove 414 is formed in the plate surface portion 412. The through groove 414 has an elongated shape that extends along the lateral direction in which the horizontal rail 3 extends.

[0020] The guide portion 413 is inclined upward from the end of the plate portion 412 on the opening 20 side. The guide portion 413 is bent and continuous from the plate portion 412.

[0021] 2 and 3, the second fitting 42 is attached to the upper part of the surface of the cross beam 3 that faces the back surface portion 21. The second fitting 42 is made of the same metal plate piece as the first fitting 41, and has an attachment surface portion 421 and a protrusion 422.

[0022] The mounting surface portion 421 is a substantially rectangular plate-like portion. Two screw holes are formed in the mounting surface portion 421, spaced apart in the longitudinal direction, and the mounting surface portion 421 is fixed to the horizontal crosspiece 3 with screws. The mounting surface portion 421 is arranged so that its long side follows the longitudinal direction of the horizontal crosspiece 3, and is attached so that its upper edge 421a, which is the upper long side, coincides with the upper end of the horizontal crosspiece 3.

[0023] Protrusion 422 is a metal plate piece that protrudes upward from the upper end of mounting surface portion 421, approximately at the center of the long side of mounting surface portion 421 in the longitudinal direction. As shown in FIG. 4B , protrusion 422 is formed in a long, narrow, approximately oval shape. The length of protrusion 422 extending in the lateral direction is shorter than the length of through groove 414, and protrusion 422 is formed to a height that allows it to engage with through groove 414 and protrude slightly from plate surface portion 412. As shown in FIG. 2 , when decorative panel 10 to which first fitting 41 is fixed is closed so as to cover opening 20, protrusion 422 of second fitting 42 engages with through groove 414 of first fitting 41.

[0024] The gap retaining members 5 are made of an elastic material such as rubber. The gap retaining members 5 are arranged, for example, on the side edge of the back surface 10b of the decorative board 10 on the side where the fixing brackets 4 are arranged, with a gap between them above and below. The gap retaining members 5 are adhered to the back surface 10b of the decorative board 10 and abut against the surfaces of the pair of side sections 24 of the box section 2 that face the decorative board 10. The gap retaining members 5 may also be arranged on the back surface 10b of the decorative board 10 in a position facing the cross rails 3 so as to abut against the cross rails 3.

[0025] The method for fixing the decorative panel 10 will be described. As shown in FIG. 1, a countertop 101 to which a sink 102 and a stove are fixed is fixed above a cabinet 104. The decorative panel 10 and the box section 2 constitute one decorative panel fixing unit 7. A plurality of decorative panel fixing units 7 are arranged side by side on the side of the cabinet 104, for example, three units are arranged side by side. In the decorative panel fixing unit 7, the box section 2 is first fixed to the side of the cabinet 104. One side of the pair of side sections 24 of the box section 2 is connected to one side of the back surface 10b of the decorative panel 10 with a hinge 6. A first metal fitting 41 of the fixing metal fitting 4 is placed on the other side of the back surface of the decorative panel 10 opposite the side to which the hinge 6 is fixed, and fixed with a screw.

[0026] The horizontal rail 3 is provided on the opening 20 side of the box section 2 and is arranged along the width direction of the opening 20 when the box section 2 is fixed to the cabinet 104. The mounting surface portion 421 of the second metal fitting 42 is fixed with a screw to the upper part of the surface of this horizontal rail 3 facing the back surface portion 21 so that the upper edge 421a is aligned with the upper edge of the horizontal rail 3. At this time, the protrusion 422 is aligned so that it passes through the through groove 414 of the first metal fitting 41. With the second metal fitting 42 attached, the decorative board 10 to which the first metal fitting 41 is fixed is closed. Then, the guide portion 413 of the first metal fitting 41 rides on the upper surface 3a of the horizontal rail 3 and guides the plate surface portion 412 of the first metal fitting 41 to the upper surface 3a. Because the first metal fitting 41 rests on the upper surface of the horizontal rail 3, even if the decorative board 10 attempts to drop downward from the attached position due to its own weight, the first metal fitting 41 prevents it from shifting in the vertical direction. When the decorative board 10 is pushed toward the rear surface portion 221, the through groove 414 of the first metal fitting 41 engages with the protrusion 422 of the second metal fitting 42. This restricts the depth direction position of the decorative board 10 to which the first metal fitting 41 is fixed. Furthermore, even if the decorative board 10 is misaligned and floats upward due to an error during installation, the engagement between the first metal fitting 41 and the second metal fitting 42 fixes the position of the decorative board 10. When it is desired to release the first metal fitting 41 and the second metal fitting 42, this can be done by pushing the bottom end of the decorative board 10 up with one's hand.

[0027] As shown in FIGS. 1 and 2, when the decorative board fixing units 7 are lined up, the hinges 6 and the fixing metal fittings are arranged alternately along the lateral direction of the cabinet 104.

[0028] This embodiment provides the following advantages. The decorative panel fixing structure 1 includes a decorative panel 10, a box section 2 having an opening 20 that is closed by the decorative panel 10 being attached, a horizontal bar 3 that is disposed opposite the decorative panel 10 and extends laterally across the opening 20, and a fixing bracket that fixes the decorative panel 10 to the horizontal bar 3. The fixing bracket 4 includes a first metal fitting 41 that is fixed to the decorative panel 10 and a second metal fitting 42 that is fixed to the horizontal bar 3. The first metal fitting 41 and the second metal fitting 42 are configured to engage with each other to regulate the position of the decorative panel 10 in the vertical and depth directions. The second metal fitting 42 engages with the first metal fitting 41, thereby fixing the positions of the decorative panel 10 and the horizontal bar 3. The decorative panel 10 is prevented from shifting upward or downward relative to the box section 2, and the decorative panel 10 is prevented from moving back and forth or rattling toward the back of the opening 20. In this way, by providing the fixing bracket 4, it is possible to prevent both the sagging or floating of the decorative panel 10 and misalignment in the depth direction, making it possible to install the decorative panel 10 with fewer parts and fewer steps, resulting in excellent workability.

[0029] According to this embodiment, the first fitting 41 is configured to include a through groove 414, and the second fitting 42 is configured to include a protrusion 422 that can engage with the through groove 414. The vertical and depth directions of the decorative panel 10 can be regulated simply by engaging the protrusion 422 with the through groove 414, thereby improving workability with a simple configuration.

[0030] According to this embodiment, through groove 414 is configured to extend long in the horizontal direction, and the horizontal length of protrusion 422 is configured to be shorter than the length of through groove 414. This makes it easier for protrusion 422 to engage with through groove 414, and even if the attachment positions of first fitting 41 and second fitting 42 or the attachment position of decorative panel 10 or the like are shifted in the horizontal direction, slight positional deviations due to construction errors can be absorbed.

[0031] According to this embodiment, the first fitting 41 includes a flat plate portion 412 that can be placed on the upper surface 3a of the horizontal bar 3, and a guide portion 413 that slopes upward from the end of the plate portion 412 that faces the opening 20 and guides the plate portion 412 to the upper surface 3a. Because the guide portion 413 slopes upward from the end of the plate portion 412 that faces the opening 20 and is placed on the upper surface of the horizontal bar 3, even if the position of the first fitting 41 is slightly misaligned vertically when the decorative board 10 is brought close to the horizontal bar 3, the guide portion 413 guides the plate portion 412 to rest on the upper surface of the horizontal bar 3. This makes it easier to close the decorative board 10 and to engage the second fitting 42 with the first fitting 41. Furthermore, the engagement between the first fitting 41 and the second fitting 42 provides the same effects as described above.

[0032] According to this embodiment, the box portion 2 includes a back portion 21 disposed on the side facing the decorative panel 10, and a pair of side portions 24 extending from a pair of opposing side edges of the back portion 21 toward the decorative panel 10. The horizontal cross bars 3 connect the ends of the pair of side portions 24 facing the decorative panel 10 to each other and are disposed with a gap between them and the back portion 21. Because the horizontal cross bars 3 are disposed with a gap between them and the back portion 21, it is possible to wire, for example, electrical cables or to place equipment that is not visible from the outside inside the box portion 2. This improves the degree of freedom in designing a kitchen unit 100 or the like in which the decorative panel 10 is disposed.

[0033] According to this embodiment, the decorative panel 10 is connected to one side in the horizontal direction by a hinge 6 so that it can be opened and closed. This makes it easy to open and close the decorative panel 10 when performing maintenance on the fixing structure 1 of the decorative panel 10 or when electrical wiring is housed inside the box portion 2.

[0034] According to this embodiment, the box section 2 and the decorative board 10 constitute a single decorative board fixing unit 7. Multiple decorative board fixing units 7 are arranged side by side, with the hinge 6 positioned on one side of the decorative board 10 in the horizontal direction and the fixing bracket 4 positioned on the other side of the decorative board 10 in the horizontal direction. With the decorative board fixing units 7 lined up, the hinges 6 and the fixing brackets 4 are arranged alternately. By placing the hinge 6 on one side of the decorative board 10 in the horizontal direction and the fixing bracket 4 on the other side, if the side not fixed by the hinge 6 sags or if there is a shift in the depth direction, the fixing bracket 4 can correct the shift in the decorative board 10. When multiple decorative board fixing units 7 are lined up, arranging the hinge 6, then the fixing bracket 4 in the horizontal direction prevents the positional shift of the decorative board 10 from being corrected, resulting in tilting and uneven surfaces with adjacent decorative boards 10.

[0035] The present disclosure is not limited to the above-described embodiments, and modifications and improvements within the scope of achieving the objectives of the present disclosure are included in the present disclosure. FIG. 5 shows a fixing bracket 4A in another embodiment. The first fixing bracket 41A has a bent portion 415 that bends downward from the end of the plate surface portion 412 on the opening 20 side. The second fixing bracket 42A has an engagement protrusion 423 that protrudes at an angle upward from the mounting surface portion 421A. The engagement protrusion 423 is positioned so that it can engage with the bent portion 415 of the first fixing bracket 41A. In other embodiments, the area of ​​the upper surface 3a of the horizontal bar 3A may be larger than in the above-described embodiment, extending, for example, to the rear surface portion 21. The bent portion 415 of the first fixing bracket 41A engages with the engagement protrusion 423 of the second fixing bracket 42A attached to the upper surface 3a of the horizontal bar 3A. In this way, the shape and configuration of the engagement between the first fixing bracket and the second fixing bracket may be modified as appropriate. [Explanation of symbols]
