Summary of the Invention

Problems to be Solved by the Invention

[0004] At the edge of the metal plate, there is a corner of the metal plate, that is, a part where the surface and the end face (cut surface) of the metal plate intersect. Such a corner may cause discomfort to the user when touched by the user's hand.

[0005] The present invention has been made in consideration of such circumstances, and an object thereof is to provide a plate-shaped component, a top plate accessory, and a method for manufacturing a plate-shaped component capable of suppressing the discomfort that may occur when touched by a user.

Means for Solving the Problems

[0006] (1) In order to solve the above problems, a plate-shaped part according to embodiment 1 of the present invention comprises a plate-shaped part made of metal having a first surface, a second surface located opposite to the first surface, and an outer peripheral edge, and a fixing part fixed to the second surface at the outer peripheral edge, the fixing part having a fixing surface fixed to the second surface, an outer surface extending away from the second surface, and a connecting surface connecting the fixing surface and the outer surface, the plate-shaped part is located at the outer peripheral edge and includes a bent portion that overlaps with the connecting surface when viewed from a direction perpendicular to the second surface, the bent portion is bent toward the connecting surface, and the first surface constitutes a curved surface.

[0007] According to embodiment 1 of the present invention, a plate-shaped component can be realized that can suppress any discomfort that may occur when a user touches it.

[0008] (2) Furthermore, in embodiment 2 of the present invention, in the plate-shaped component of embodiment 1, the connecting surface is a curved surface that is convex toward the outside of the fixing component.

[0009] According to aspect 2 of the present invention, the process of bending the bent portion to make the first surface of the bent portion a curved surface becomes easier.

[0010] (3) Furthermore, in embodiment 3 of the present invention, in the plate-shaped part of embodiment 1 or embodiment 2, the outer peripheral edge includes a curved portion that extends in a curved shape when viewed from the orthogonal direction, the fixed surface is fixed to the second surface in the curved portion, and the bent portion is located in the curved portion.

[0011] According to embodiment 3 of the present invention, even in curved sections that are difficult to bend, it is possible to suppress any discomfort that may occur when a user touches them.

[0012] (4) Furthermore, in embodiment 4 of the present invention, in any one of embodiments 1 to 3, the outer peripheral edge includes a straight portion that extends linearly when viewed from the orthogonal direction, and in the straight portion, the plate-like portion is bent toward the second surface side in the orthogonal direction.

[0013] According to aspect 4 of the present invention, a configuration that suppresses discomfort when a user comes into contact with a straight section can be easily realized.

[0014] (5) Furthermore, aspect 5 of the present invention further comprises a plate-shaped base material located on the second surface side with respect to the plate-shaped portion and overlapping the plate-shaped portion when viewed from the orthogonal direction, in any one of the plate-shaped parts from aspect 1 to aspect 4.

[0015] According to aspect 5 of the present invention, the base material can shield the plate-like portion from below, thereby enhancing the aesthetic appeal of the plate-like component.

[0016] (6) Furthermore, aspect 6 of the present invention further comprises a reinforcing member that reinforces the plate-shaped portion in any one of aspects 1 to 5.

[0017] According to embodiment 6 of the present invention, the strength of the plate-like portion can be increased.

[0018] (7) Furthermore, the fixture with a top plate according to embodiment 7 of the present invention comprises a top plate which is a plate-shaped component from any one of embodiments 1 to 6, and a support structure which supports the top plate.

[0019] According to aspect 7 of the present invention, it is possible to realize a fixture with a top plate that can suppress any discomfort that may occur when a user touches it.

[0020] (8) In order to solve the above problems, a method for manufacturing a plate-shaped part according to embodiment 8 of the present invention includes a preparation step of preparing a plate-shaped part made of metal having a first surface, a second surface located on the opposite side of the first surface, and an outer peripheral edge, and a fixing part having a fixing surface, an outer surface facing an intersecting direction that intersects with the orthogonal direction perpendicular to the fixing surface, and a connecting surface connecting the fixing surface and the outer surface, a fixing step of fixing the fixing surface to the second surface at the outer peripheral edge so that there is a gap between the connecting surface and the second surface at the outer peripheral edge, and a bending step of bending the outer peripheral edge toward the connecting surface so that a bent portion is formed at the outer peripheral edge where the first surface constitutes a curved surface.

[0021] According to aspect 8 of the present invention, a plate-shaped component capable of suppressing a sense of discomfort that may occur when touched by a user can be manufactured.

[0022] (9) Further, aspect 9 of the present invention is a method for manufacturing the plate-shaped component according to aspect 8. In the preparation step, the plate-shaped portion has an outer end face facing the outside in the intersecting direction. In the bending step, from a state where the outer end face of the plate-shaped portion and the outer side face of the fixing component are on the same plane, the outer peripheral edge portion is bent toward the connecting surface.

[0023] According to aspect 9 of the present invention, at the end of the bending step, the difference in position in the intersecting direction between the outer end (the end portion on the outer side in the intersecting direction) of the plate-shaped portion and the outer side face of the fixing component can be reduced. [Advantages of the Invention]

[0024] According to the above aspects of the present invention, it is possible to provide a plate-shaped component, a top plate accessory, and a method for manufacturing the plate-shaped component that can suppress a sense of discomfort that may occur when touched by a user.

[Figure 9] This is a cross-sectional view showing a plate-shaped component according to a third embodiment of the present invention. [Modes for carrying out the invention]

[0026] (First Embodiment) The following describes, based on the drawings, a plate-shaped component, a fixture with a top plate, and a method for manufacturing the plate-shaped component according to the first embodiment.

[0027] <Display fixture with tabletop> Figure 1 is an exploded view showing a fixture 100 with a tabletop according to the first embodiment of the present invention. As shown in Figure 1, the furniture with a tabletop 100 according to this embodiment comprises a plate-shaped component 1 and a support structure 2. The furniture with a tabletop 100 is a table (high table) used by being placed on the floor surface F of, for example, an office or a conference room in a public facility. In the furniture with a tabletop 100, the plate-shaped component 1 is also referred to as the tabletop.

[0028] In the following explanation, the direction that intersects (for example, perpendicular to) the floor surface F is referred to as the vertical direction Z. The vertical direction Z may be, for example, parallel to gravity (i.e., vertical) or inclined with respect to the vertical direction. One direction that intersects (for example, perpendicular to) the vertical direction Z is referred to as the width direction X. The direction that intersects (for example, perpendicular to) both the vertical direction Z and the width direction X is referred to as the depth direction Y. The width direction X and the depth direction Y may be perpendicular to gravity (i.e., horizontal) or inclined with respect to the horizontal direction. Along the vertical direction Z, the direction moving away from the floor surface F towards the top-mounted fixture 100 is referred to as upward, and is represented by the +Z direction in the diagram. The direction opposite to upward is referred to as downward, and is represented by the -Z direction in the diagram. One direction along the width direction X is referred to as rightward, and is represented by the +X direction in the diagram. The direction opposite to the right is called the left, and is represented by the -X direction in the diagram. One direction along the depth direction Y is called the rear or far side, and is represented by the +Y direction in the diagram. The direction opposite to the rear is called the front or near side, and is represented by the -Y direction in the diagram. Viewing from the vertical direction Z is called a plan view. In the width direction X, the direction toward the center O in a plan view of the plate-shaped part 1 (plate-shaped part 10) is sometimes called the "inside of the width direction X," and the direction away from the center O is sometimes called the "outside of the width direction X." Similarly, in the depth direction Y, the direction toward the center O is sometimes called the "inside of the depth direction Y," and the direction away from the center O is sometimes called the "outside of the depth direction Y." In addition, a direction that intersects (for example, is perpendicular to) the vertical direction Z is called the intersecting direction. The above-mentioned width direction X and depth direction Y are examples of intersecting directions. In the direction of intersection, the direction toward the center O is sometimes referred to as the "inside direction of intersection." In the direction of intersection, the direction away from the center O is sometimes referred to as the "outside direction of intersection."

[0029] <Support structure> The support structure 2 has at least one ground contact portion CT that contacts the floor surface F. In the illustrated example, the support structure 2 has four legs 2a connected to the plate-shaped component 1 (more specifically, the lower surface of the base portion 31, which will be described later). A ground contact portion CT is provided at the lower end of each leg portion 2a. However, the shape and configuration of the support structure 2 are not particularly limited as long as the plate-shaped component 1 can be supported from below, and can be modified as appropriate.

[0030] <Plate-shaped parts> Figure 2 is an exploded view showing a part of a plate-shaped component 1 according to the first embodiment of the present invention. Figure 3 is a cross-sectional view taken along the line III-III shown in Figure 1. Figure 4 is a cross-sectional view taken along the line IV-IV shown in Figure 1. As shown in Figures 1 to 4, the plate-shaped component 1 according to this embodiment comprises a plate-shaped portion 10, a plurality of (four in the illustrated example) fixing components 20, a base material 30, a plurality of (nine in the illustrated example) first reinforcing members 41, and a plurality of (four in the illustrated example) second reinforcing members 42. The plate-shaped component 1 as a whole has a plate-like shape extending in the width direction X and the depth direction Y (see Figure 1).

[0031] <Plate-like part> As shown in Figure 1, the plate-like portion 10 according to this embodiment has a base portion 11 and a plurality (four in the illustrated example) bent portions 13. The plate-like portion 10 is made of metal.

[0032] The base portion 11 is a plate-like portion extending in the width direction X and the depth direction Y. As shown in Figures 1 and 3, the base portion 11 (plate-like portion 10) has a first surface 11a and a second surface 11b. The second surface 11b is located on the opposite side from the first surface 11a. In this embodiment, the first surface 11a faces upward and the second surface 11b faces downward. In this embodiment, the orthogonal direction perpendicular to the second surface 11b coincides with the vertical direction Z. The base portion 11 has an outer peripheral edge portion 12.

[0033] The outer peripheral edge portion 12 is the part of the base portion 11 located on the outer peripheral edge of the base portion 11 (plate-shaped portion 10) in a plan view. The outer peripheral edge portion 12 has an annular shape in a plan view. In this specification, the term "annular shape" does not mean only a circular annular shape, but also includes shapes other than an annular shape, such as a rectangular annular shape. "Annular shape" can also be read as "loop shape" or "closed loop shape". As shown in Figure 1, the outer peripheral edge portion 12 according to this embodiment includes four straight portions 12a and four curved portions 12b.

[0034] Each straight section 12a extends in a straight line in a plan view. More specifically in this embodiment, two of the four straight sections 12a extend in the width direction X, and the remaining two straight sections 12a extend in the depth direction Y. Furthermore, these four straight sections 12a are arranged to form a rectangular shape with sides extending in the width direction X and the depth direction Y. As a result, the base 11 has a substantially rectangular shape in a plan view.

[0035] Each curved section 12b extends in a curved shape (for example, an arc shape) in a plan view. Specifically, each curved section 12b has a curved shape that is convex outward in the direction of intersection. The four curved sections 12b and the four straight sections 12a are arranged alternately along the outer edge 12. Each curved section 12b extends so as to connect two adjacent straight sections 12a.

[0036] Each curved portion 12b constitutes a corner portion CN in a plan view of the base portion 11 (plate-like portion 10). That is, the base portion 11 (outer peripheral edge portion 12) according to this embodiment includes four corner portions CN. The corner portions CN are the parts of the base portion 11 that are located at the corners of the base portion 11 (plate-like portion 10) in a plan view.

[0037] In the illustrated example, the dimension of the base 11 (plate-shaped portion 10) in the width direction X is longer than the dimension of the base 11 (plate-shaped portion 10) in the depth direction Y. However, the dimension of the base 11 (plate-shaped portion 10) in the width direction X may be less than or equal to the dimension of the base 11 (plate-shaped portion 10) in the depth direction Y.

[0038] As shown in Figures 1 and 3, the bent portion 13 is connected to the straight portion 12a of the base portion 11 (plate-shaped portion 10). As shown in Figure 3, the bent portion 13 according to this embodiment has a first bent portion 13a, a second bent portion 13b, and a third bent portion 13c.

[0039] The first bent portion 13a is a portion that extends downward from the outer peripheral edge (straight portion 12a) of the base portion 11. The second bent portion 13b is a portion that extends inward in the intersecting direction (towards the -Y side in the example of Figure 3) from the lower end of the first bent portion 13a. The third bent portion 13c is a portion of the second bent portion 13b that extends upward from the inner end in the intersecting direction.

[0040] The first bent portion 13a has an outer surface 13a1 facing outward in the intersecting direction (towards +Y in the example of Figure 3). The outer surface 13a1 constitutes a part of the outer surface (i.e., the surface facing outward in the intersecting direction) of the plate-like portion 10 (plate-like component 1).

[0041] The bent portion 13 described above is formed by bending the metal plate for forming the plate-like portion 10 toward the second surface 11b side (i.e., downward side) at the portion corresponding to the straight portion 12a. In other words, the boundary connection surface BD between the first surface 11a of the base portion 11 and the outer surface 13a1 of the bent portion 13 is a bent surface formed as a result of this bending process, and is a curved surface. Specifically, the boundary connection surface BD is a curved surface that is convex toward the outside of the plate-like portion 10.

[0042] Figure 5 is a plan view showing an example of a metal plate 10' for forming a plate-like portion 10 according to the first embodiment of the present invention. That is, the plate-like portion 10 according to this embodiment is formed by bending the metal plate 10'. As shown in Figure 5, the metal plate 10' has a base portion 11' and four bent pieces 13'. The base portion 11' corresponds to the base portion 11 described above, and the bent pieces 13' correspond to the bent portion 13 described above. The side 12a' corresponds to the straight portion 12a described above. The base portion 11' has a rectangular shape in plan view and has four sides 12a'. The curved portions 12b described above are pre-formed at the corners of the base portion 11'. The four bent pieces 13' constitute the outer edge of the metal plate 10'. The four bent pieces 13' correspond one-to-one with the four sides 12a' of the base portion 11'. Each bent piece 13' extends outward in the intersecting direction from the corresponding side 12a'. Due to the presence of the bent pieces 13', the metal plate 10' is larger in size than the base portion 11 (plate-like portion 10) in both the width direction X and the depth direction Y. In such a metal plate 10', by bending the folding piece 13' toward the second surface 11b side (the back side of the paper in Figure 5), the base portion 11', the folding piece 13', and the edge 12a' become the base portion 11, the folded portion 13, and the straight portion 12a, respectively, and the plate-like portion 10 described above is formed.

[0043] As shown in Figures 1 and 2, the curved portion 12b (corner portion CN) of the base portion 11 does not have the bent portion 13 described above. Instead of the bent portion 13, a fixing part 20 is provided on the curved portion 12b (corner portion CN) of the base portion 11. Details of the shape of the plate-shaped part 1 on the curved portion 12b (corner portion CN) will be described later, along with the manufacturing method of the plate-shaped part 1.

[0044] <Base material> As shown in Figure 1, the base material 30 is a plate-shaped member located below (towards the second surface 11b) the plate-shaped portion 10 and overlapping the plate-shaped portion 10 in a plan view. The base material 30 has a base portion 31 and a bent portion 33. The base portion 31 and the bent portion 33 are formed, for example, from a metal plate.

[0045] The base portion 31 is a plate-shaped part that extends in the width direction X and the depth direction Y. The base portion 31 is provided in a position that overlaps with the base portion 11 of the plate-shaped part 10 in a plan view. The lower surface of the base portion 31 may be provided with a fixing mechanism (not shown) for fixing the support structure 2 (e.g., screw holes).

[0046] The outer peripheral edge portion 32 is the part of the base portion 31 located at the outer peripheral edge of the base portion 31 (base material 30) in a plan view. The outer peripheral edge portion 32 has an annular shape in a plan view. The shape of the outer peripheral edge portion 32 corresponds to the shape of the outer peripheral edge portion 12 described above. That is, the outer peripheral edge portion 32 in this embodiment includes four straight portions 32a and four curved portions 32b, similar to the outer peripheral edge portion 12.

[0047] Each straight section 32a extends linearly along the straight section 12a in a plan view. Specifically, two of the four straight sections 32a extend in the width direction X, and the remaining two extend in the depth direction Y. Furthermore, these four straight sections 32a are arranged to form a rectangular shape with sides extending in the width direction X and the depth direction Y. As a result, the base 31 has a substantially rectangular shape in a plan view.

[0048] Each curved section 32b extends along the curved section 12b in a curved shape (for example, an arc shape) in a plan view. Specifically, each curved section 32b has a curved shape that is convex outward in the direction of intersection. The four curved sections 32b and the four straight sections 32a are arranged alternately. Each curved section 32b extends so as to connect two adjacent straight sections 32a. Each curved section 32b constitutes a corner of the base section 31 (base material 30) in a plan view.

[0049] As shown in Figures 1 and 3, the bent portion 33 is connected to the straight portion 32a of the base portion 31 (substrate 30). As shown in Figure 3, the bent portion 33 according to this embodiment has a first bent portion 33a and a second bent portion 33b.

[0050] The first bent portion 33a is the portion that extends upward from the outer peripheral edge (straight portion 32a) of the base portion 31. The second bent portion 33b is the portion that extends inward in the intersecting direction from the upper end of the first bent portion 33a.

[0051] As shown in Figure 3, the upper surface of the second bent portion 33b is in contact with the second surface 11b of the plate-like portion 10. In this embodiment, the base material 30 is fixed to the second surface 11b by welding the upper surface of the second bent portion 33b to the second surface 11b.

[0052] In both the width direction X and the depth direction Y, the base material 30 is formed to be slightly smaller than the plate-like portion 10. Specifically, the dimensions of the base material 30 are set to be smaller than the dimensions of the plate-like portion 10 to the extent that, when the base material 30 is fixed to the second surface 11b, the bent portion 33 is located on the inside in the intersecting direction of the bent portion 13 (towards the -Y side in the example of Figure 3). More specifically, when the base material 30 is fixed to the second surface 11b, the first bent portion 33a of the bent portion 33 and the third bent portion 13c of the bent portion 13 face each other in the intersecting direction (depth direction Y in the example of Figure 3). As shown in the example of Figure 3, when the base material 30 is fixed to the second surface 11b, the lower surface of the base portion 31 and the lower surface of the bent portion 13 (the lower surface of the second bent portion 13b) may be located on the same plane.

[0053] As shown in Figures 1 and 4, the curved portion 32b (corner portion) of the base material 30 does not have the aforementioned bent portion 33. As shown in Figure 4, in the curved portion 32b, the base portion 31 has a notch 31a that opens outward in the intersecting direction. The notch 31a penetrates the base portion 31 in the vertical direction Z. A fixing component 20 (specifically, the bottom wall portion 23, which will be described later) is placed in the notch 31a.

[0054] <Reinforcement member> The reinforcing members 41 and 42 are configured to reinforce the plate-like portion 10. As shown in Figures 1 and 3, the reinforcing members 41 and 42 are provided between the base portions 11 and 31 in the vertical direction Z.

[0055] As shown in Figure 1, the first reinforcing member 41 extends in the width direction X. In this embodiment, a plurality of first reinforcing members 41 are arranged at intervals in the depth direction Y. As shown in Figure 3, the first reinforcing member 41 in this embodiment has a fixing portion 41a, a pair of upright portions 41b, and a pair of contact portions 41c. The first reinforcing member 41 may be, for example, a so-called rectangular tube.

[0056] The fixed portion 41a is a portion that extends in the width direction X. The fixed portion 41a is fixed to the base portion 31 by any method such as screw fastening.

[0057] The pair of upright portions 41b are portions that extend upward from both ends of the fixed portion 41a in the depth direction Y.

[0058] The pair of contact portions 41c are portions that extend from the upper ends of the pair of upright portions 41b so as to move closer to each other in the depth direction Y. When the base material 30 is fixed to the second surface 11b, the upper surface of the contact portions 41c is in contact with the second surface 11b. In this way, the first reinforcing member 41 reinforces the plate-like portion 10. The upper surface of the contact portions 41c may be fixed to the second surface 11b by any method such as welding. The first reinforcing member 41 may take on a so-called hat shape by having the contact portions 41c extend from the upper ends of the pair of upright portions 41b so as to move further apart from each other in the depth direction Y.

[0059] As shown in Figure 1, the second reinforcing member 42 is a thick plate-shaped member. In this embodiment, four second reinforcing members 42 are provided corresponding to the four corners CN of the plate-shaped portion 10. The second reinforcing members 42 may be made of, for example, MDF (medium-density fiberboard).

[0060] The second reinforcing member 42 has a fitting hole 42a that penetrates the second reinforcing member 42 in the vertical direction Z. A fitting projection (not shown) formed on the upper surface of the base 31 is fitted into the fitting hole 42a. In this embodiment, the fitting projection is fitted into the fitting hole 42a, thereby positioning the second reinforcing member 42 relative to the base 31. The second reinforcing member 42 may be further fixed to the base 31 by any fixing method such as adhesive.

[0061] As shown in Figure 3, the second reinforcing member 42 according to this embodiment is positioned on the base 31 with a predetermined gap in the vertical direction Z between it and the second surface 11b. The base 11, which is made of a metal plate, may bend downward due to external forces applied by the user or the like. The second reinforcing member 42 contacts the second surface 11b when the base 11 bends in this way, thereby suppressing excessive bending of the base 11. In this way, the second reinforcing member 42 reinforces the plate-like portion 10. Furthermore, as shown in Figure 1, the second reinforcing member 42 according to this embodiment has a protruding portion 42b that protrudes outward in the intersecting direction at the curved portion 32b (corner portion).

[0062] <Fixing parts> As shown in Figures 2 and 4, the fixing part 20 is a part that is fixed to the second surface 11b of the plate-shaped part 10 at the curved portion 12b (corner portion CN) of the plate-shaped part 10. As shown in Figure 4, the fixing part 20 according to this embodiment has a fixing part 21, a side wall part 22, a bottom wall part 23, a connecting part 24, and a second connecting part 25.

[0063] The fixing portion 21 is the part that is fixed to the second surface 11b. The fixing portion 21 has a fixing surface 21a that is fixed to the second surface 11b. In this embodiment, the fixing surface 21a is a flat surface facing upward and is perpendicular to the vertical direction Z. In this embodiment, at least a part of the fixing portion 21 (the part located on the inside in the intersecting direction) is in a position that overlaps with the base material 30 in a plan view. As shown in Figure 2, the fixing portion 21 in this embodiment has a main portion 21b and a plurality of extension portions 21c.

[0064] The main portion 21b is a part that extends along the side wall portion 22 and has a curved shape (e.g., an arc) in a plan view. The main portion 21b is connected to the side wall portion 22 via a connecting portion 24.

[0065] The extension portion 21c is a part that extends inward from the main portion 21b in a direction that intersects it. Multiple extension portions 21c are arranged at intervals along the side wall portion 22. In this embodiment, the upper surface of the main portion 21b and the upper surface of the extension portion 21c correspond to the aforementioned fixing surface 21a. By providing the extension portion 21c, the fixing strength of the fixing surface 21a to the second surface 11b can be increased. However, if the fixing strength of the plate-like portion 10 and the fixing part 20 can be ensured by fixing the main portion 21b and the second surface 11b alone, the extension portion 21c does not need to be provided on the fixing portion 21. In other words, the specific shape of the fixing portion 21 is not limited as long as it follows the plan view shape of the outer peripheral edge of the plate-like portion 10 and has a fixing surface 21a which is a flat surface facing the second surface 11b in the vertical direction Z.

[0066] As shown in Figure 4, the side wall portion 22 is a part that is connected to the outer end of the fixing portion 21 in the intersecting direction via the connecting portion 24. The side wall portion 22 extends away from the second surface 11b in the vertical direction Z (i.e., downward). The side wall portion 22 has an outer surface 22a that faces outward in the intersecting direction. The outer surface 22a constitutes a part of the outer surface of the plate-shaped component 1. The outer surface 22a extends away from the second surface 11b in the vertical direction Z.

[0067] The bottom wall portion 23 is the part connected to the lower end of the side wall portion 22 via the second connecting portion 25. The bottom wall portion 23 extends inward in the intersecting direction. The lower surface of the bottom wall portion 23 may be on the same plane as the lower surface of the base portion 31.

[0068] The connecting portion 24 is the part that connects the fixing portion 21 and the side wall portion 22. The connecting portion 24 has a connecting surface 24a that connects the fixing surface 21a of the fixing portion 21 and the outer surface 22a of the side wall portion 22. In this embodiment, the connecting surface 24a is a curved surface that is convex toward the outside of the fixing component 20.

[0069] The connecting surface 24a has an inner edge 24a1 that connects to the fixing portion 21 and an outer edge 24a2 that connects to the side wall portion 22. The inner edge 24a1 is in contact with the second surface 11b. The outer edge 24a2 is located below the inner edge 24a1 and outward in the intersecting direction. As a result, the connecting surface 24a forms a step ST with respect to the fixing surface 21a in a direction away from the second surface 11b (i.e., downward).

[0070] The second connecting portion 25 is the part that connects the side wall portion 22 and the bottom wall portion 23. It has a second connecting surface 25a that connects the outer surface 22a of the side wall portion 22 and the lower surface of the bottom wall portion 23. In this embodiment, the second connecting surface 25a is a curved surface that is convex toward the outside of the fixing part 20.

[0071] The fixing part 20 having the aforementioned parts 21 to 25 is formed, for example, by bending a metal plate. In this embodiment, the connecting surface 24a and the second connecting surface 25a are bent surfaces formed as a result of such bending. The aforementioned convex curved shape of the connecting surface 24a and the second connecting surface 25a is formed as a result of such bending.

[0072] <Shape of plate-like component at corner, and manufacturing method of plate-like component> The shape of the plate-shaped part 1 in the curved section 12b (corner section CN) will be described in detail below, along with the manufacturing method of the plate-shaped part 1.

[0073] Figure 6 is a cross-sectional view showing the manufacturing process of a plate-shaped component 1 according to the first embodiment of the present invention. Figure 7 is a flowchart showing the manufacturing method of the plate-shaped component 1 according to the first embodiment of the present invention. As shown in Figure 7, the plate-shaped part 1 according to this embodiment is manufactured by performing the following steps in this order: preparation step S101, fixing step S102, bending step S103, painting step S104, and base material fixing step S105. The upper part of Figure 6 shows the point at the end of the fixing step S102, and the lower part of Figure 6 shows the point at the end of the painting step S104.

[0074] (Preparation step S101) In preparation step S101, the plate-shaped portion 10, the fixing part 20, and the base material 30 are prepared. In preparation step S101, the plate-shaped portion 10 may have the bent portion 13 formed in advance, and the base material 30 may have the bent portion 33 formed in advance. Also, each of the reinforcing members 41 and 42 may be fixed to the plate-shaped portion 10 or the base material 30 in advance.

[0075] In preparation step S101, the plate-like portion 10 has an outer end surface 11c located at the curved portion 12b (corner CN) and facing outward in the intersecting direction. The outer end surface 11c extends in a curved shape in plan view along the curved portion 12b (corner CN) and is a surface that connects surfaces 11a and 11b in the vertical direction Z. The outer end surface 11c may be, for example, a cut surface obtained by cutting a metal plate.

[0076] In preparation step S101, the plate-like portion 10 has corners E1 and E2. Corner (upper corner) E1 is the part where the first surface 11a and the outer end surface 11c intersect at a predetermined angle (for example, 90°). Corner (lower corner) E2 is the part where the second surface 11b and the outer end surface 11c intersect at a predetermined angle (for example, b, 90°).

[0077] In preparation step S101, the entire base portion 11 is a flat portion 14 that extends flatly in the width direction X and the depth direction Y. Furthermore, the entire first surface 11a is a flat surface (first flat surface 14a), and the entire second surface 11b is also a flat surface (second flat surface 14b).

[0078] (Fixed process S102) In the fixing process S102, the fixing surface 21a of the fixing component 20 is fixed to the second surface 11b of the plate-shaped portion 10 at the curved portion 12b (corner portion CN) of the plate-shaped portion 10. The method of fixing the fixing surface 21a to the second surface 11b is not particularly limited, but fixing by welding, for example, may be performed. In this embodiment, this fixing is performed in a manner that satisfies the first and second conditions shown below (see upper part of Figure 6).

[0079] The first condition is that a gap GP is created between the plate-like portion 10 (second surface 11b) and the connecting surface 24a of the fixing component 20 at the curved portion 12b (corner portion CN). Here, the gap GP may be defined as a region located below the interface BS (see upper part of Figure 6) between the plate-like portion 10 and the fixing component 20, and overlapping both the plate-like portion 10 (base portion 11) and the connecting surface 24a in the vertical direction Z. The interface BS is a hypothetical flat surface including the fixing surface 21a. In the fixing process S102, the region located between the second surface 11b and the connecting surface 24a in the vertical direction Z corresponds to the gap GP.

[0080] The second condition is that the outer end surface 11c of the plate-like portion 10 and the outer surface 22a of the fixing component 20 are on the same plane. As a result, in this embodiment, the subsequent bending process S103 begins with the outer end surface 11c and the outer surface 22a on the same plane.

[0081] In the fixing process S102, the side wall portion 22 of the fixing part 20 may be fixed to the bent portion 13 of the plate-shaped portion 10 (see Figure 2). For example, the side wall portion 22 may be welded to the bent portion 13.

[0082] (Bending process S103) In bending step S103, the curved portion 12b (corner portion CN) is bent toward the connecting surface 24a, thereby forming a bent portion 15 on the curved portion 12b (see lower part of Figure 6). As a result of bending step S103, the base portion 11 has a flat portion 14 and a bent portion 15. The bent portion 15 is located on the curved portion 12b (corner portion CN) and overlaps with the connecting surface 24a in a plan view. The bent portion 15 is bent toward the connecting surface 24a (i.e., downward).

[0083] In the bent portion 15, the first surface 11a constitutes the first bent surface 15a, and the second surface 11b constitutes the second bent surface 15b. Both bent surfaces 15a and 15b constitute curved surfaces. The first bent surface 15a is a curved surface that is convex toward the outside of the plate-shaped part 1. The second bent surface 15b is a curved surface that is concave toward the outside of the plate-shaped part 1.

[0084] The bent portion 15 may be formed, for example, by crushing the curved portion 12b (corner portion CN) downward. In this embodiment, the corner E1 disappears from the base portion 11 by performing the bending process S103. Specifically, the corner E1 disappears by forming the bent portion 15 (i.e., crushing the curved portion 12b) such that the first bent surface 15a smoothly connects the first flat surface 14a and the corner E2.

[0085] Of the bent portion 15 formed by the bending process S103, the portion located below the interface surface BS functions as a filling portion FL that fills at least a part of the gap GP. In other words, the bending process S103 also acts as a filling process to fill at least a part of the gap GP with a filler material (plate-shaped portion 10) to form the filling portion FL. In this embodiment, the bent portion 15 is formed (crushed) such that a space remains between the second bent surface 15b and the first flat surface 14a.

[0086] (Painting process S104) In painting step S104, the plate-shaped portion 10, the fixing part 20 fixed thereto, and the base material 30 are painted with paint. For example, the plate-shaped portion 10, the fixing part 20, and the base material 30 may be painted with the same paint. By performing such painting on the plate-shaped portion 10, the fixing part 20, and the base material 30, a coating film 50 formed by solidified paint is provided on the plate-shaped portion 10, the fixing part 20, and the base material 30 (for example, around the curved portion 12b (corner CN)). Note that in Figures 1 to 4, the illustration of the coating film 50 is omitted for clarity.

[0087] In this embodiment, the coating film 50 includes a first coating film 50a, a second coating film 50b, and a third coating film 50c. The first coating film 50a is the portion of the coating film 50 that is applied to (in contact with) the connecting surface 24a. The second coating film 50b is the portion of the coating film 50 that is applied to (in contact with) the outer surface 22a. The third coating film 50c is the portion of the coating film 50 that is applied to (in contact with) the first surface 11a (first flat surface 14a and first curved surface 15a). The first coating film 50a, the second coating film 50b, and the third coating film 50c are formed by the solidification of the same paint. In addition, in this embodiment, a part of the coating film 50 (the first coating film 50a) also penetrates into the space between the connecting surface 24a and the second curved surface 15b. Furthermore, the coating film 50 covers the corner E2 of the base 11, so that the corner E2 is not exposed to the outside of the plate-shaped part 1. Paints for forming the coating films 50a to 50c may be applied so that the outer surfaces (the surfaces facing outward from the plate-shaped part 1) are smoothly connected by the coating films 50a to 50c.

[0088] Of the coating film 50 formed by the painting process S104, the portion located below the interface BS and above the connecting surface 24a (first coating film 50a) functions as a filling portion FL that fills at least a part of the gap GP. In other words, the painting process S104 also functions as a filling process that fills at least a part of the gap GP with a filler (paint) to form the filling portion FL.

[0089] In other words, the filling portion FL according to this embodiment includes at least a part of the bent portion 15 and at least a part of the coating film 50. Furthermore, the filling portion FL has an outer surface FLa that faces outward in the intersecting direction. In this embodiment, the outer surface FLa corresponds to the outer surface of the coating film 50.

[0090] The paint used to form the second coating film 50b and the third coating film 50c may be different from the paint used to form the first coating film 50a as part of the filling portion FL on the curved portion 12b. The filling portion FL may be formed on the curved portion 12b using a filler specifically designed for filling, and then painted with the paint used to form the second coating film 50b and the third coating film 50c. In this case, the coating film may or may not be laminated on the upper layer of the filling portion FL using the paint used to form the second coating film 50b and the third coating film 50c. The paint used to form the second coating film 50b and the paint used to form the third coating film 50c may be different from each other.

[0091] (Base material fixing process S105) In the base material fixing step S105, the base material 30 is fixed to the second surface 11b of the plate-like portion 10. Specifically in this embodiment, the upper surface of the second bent portion 33b is welded (pressure bonded) to the second surface 11b (see also Figure 3).

[0092] The manufacturing of the plate-shaped part 1 is completed by the above steps S101 to S105. The top-mounted fixture 100 may be manufactured by further performing the step of fixing the support structure 2 to the plate-shaped part 1.

[0093] <effect> Next, the operation of the plate-shaped component 1, which is configured as described above, will be explained.

[0094] Conventionally, plate-shaped components made of metal sheets are known. At the edges of these metal sheets, there are corners, that is, points where the surface of the metal sheet intersects with the end face (cut surface). Such corners can cause discomfort to the user when they come into contact with their hands.

[0095] To address this issue, the plate-shaped part 1 according to this embodiment includes a fixing part 20 having a fixing surface 21a and a connecting surface 24a. As described above, the fixing surface 21a is fixed to the second surface 11b at the outer peripheral edge 12 (in the above example, the corner CN which is the curved part 12b), and the connecting surface 24a forms a step ST that is directed downward with respect to the fixing surface 21a. Furthermore, the plate-shaped part 10 has a bent portion 15. Here, the bent portion 15 overlaps with the connecting surface 24a in a plan view and is bent toward the connecting surface 24a, so that the first surface 11a constitutes a curved surface (first bent surface 15a). This makes it possible to suppress the discomfort experienced by the user when they touch the edge of the first surface 11a. In particular, the configuration in which the corner E1 is eliminated by crushing the outer peripheral edge 12 (see lower part of Figure 6) is more preferable in that it can more reliably suppress the discomfort experienced by the user.

[0096] In the example described above, the fixing part 20 is fixed to the second surface 11b at the curved section 12b (corner section CN), but the fixing part 20 may also be fixed to the second surface 11b at the straight section 12a. That is, the fixing part 20 only needs to be fixed to the second surface 11b at some part of the outer peripheral edge 12 (hereinafter referred to as the outer peripheral fixing part). In this case, in the fixing process S102 described above, the connecting surface 24a is fixed to the second surface 11b at the outer peripheral edge 12 (outer peripheral fixing part) so that a gap GP is created between the connecting surface 24a and the second surface 11b at the outer peripheral edge 12 (outer peripheral fixing part). Furthermore, in the bending process S103, the outer peripheral edge 12 (outer peripheral fixing part) is bent toward the connecting surface 24a to form the bent section 15. This configuration also provides the same effect as the example described above, in suppressing discomfort for the user.

[0097] <Summary> As described above, the plate-shaped part 1 according to this embodiment comprises a plate-shaped part 10 made of metal, having a first surface 11a, a second surface 11b located on the opposite side of the first surface 11a, and an outer peripheral edge 12, and a fixing part 20 fixed to the second surface 11b at the outer peripheral edge 12. The fixing part 20 has a fixing surface 21a fixed to the second surface 11b, an outer surface 22a extending away from the second surface 11b, and a connecting surface 24a connecting the fixing surface 21a and the outer surface 22a. The plate-shaped part 10 is located at the outer peripheral edge 12 and includes a bent portion 15 that overlaps with the connecting surface 24a when viewed from an orthogonal direction (up and down direction Z) perpendicular to the second surface 11b. The bent portion 15 is bent toward the connecting surface 24a, and the first surface 11a constitutes a curved surface (first bent surface 15a). This configuration makes it possible to create a plate-shaped component 1 that can suppress any discomfort that may occur when the user touches it.

[0098] Furthermore, the connecting surface 24a is a curved surface that is convex toward the outside of the fixing part 20. This configuration makes it easier to bend the bending portion 15 and make the first surface 11a (first bending surface 15a) of the bending portion 15 a curved surface.

[0099] Furthermore, the outer peripheral edge portion 12 includes a curved portion 12b (corner portion CN) that extends in a curved shape in a plan view, the fixed surface 21a is fixed to the second surface 11b in the curved portion 12b, and the bent portion 15 is located in the curved portion 12b. In this embodiment, the plate-like portion 10 is bent to provide the bent portion 13 in the straight portion 12a. As described above, the boundary connection surface BD between the first surface 11a of the base portion 11 and the outer surface 13a1 of the bent portion 13 is a bent surface formed due to the bending process and is a curved surface. Therefore, any discomfort that may occur when a user touches it can be suppressed by this curved boundary connection surface BD. This method of suppressing discomfort using such a boundary connection surface BD is suitable because it can be achieved by the simple method of bending. However, it is difficult to perform such bending on the curved corner portion CN of the plate-like portion 10, i.e., the curved portion 12b. Therefore, in this embodiment, a fixing part 20 is provided on the curved portion 12b (corner portion CN). Furthermore, in the curved section 12b (corner section CN), the first bent surface 15a of the bent section 15 helps to suppress any feeling of discomfort. In this way, by using the fixing part 20 and the bent section 15, it is possible to suppress any feeling of discomfort that may occur when a user touches the curved section 12b (corner section CN), which is difficult to bend.

[0100] Furthermore, the outer edge portion 12 includes a straight portion 12a that extends in a straight line when viewed from above, and in the straight portion 12a, the plate-like portion 10 is bent toward the second surface 11b side (downward) in the vertical direction Z. That is, a fixing part 20 is provided in the curved portion 12b (corner portion CN), while a bent portion 13 is provided in the straight portion 12a. In this way, by introducing the bent portion 13 in the straight portion 12a, which is easy to bend, it is possible to easily realize a configuration that suppresses the discomfort that may occur when the user comes into contact with the straight portion 12a.

[0101] Furthermore, the plate-shaped component 1 according to this embodiment further comprises a plate-shaped base material 30 located on the second surface 11b side (downward) relative to the plate-shaped portion 10, and overlapping the plate-shaped portion 10 in a plan view. This configuration allows the base material 30 to shield the plate-shaped portion 10 from below, thereby enhancing the aesthetic appeal of the plate-shaped component 1. In particular, the configuration in which at least a portion of the fixing portion 21 overlaps with the base material 30 in a plan view is preferable because the base material 30 shields at least a portion of the fixing portion 21 from below, further enhancing the aesthetic appeal.

[0102] Furthermore, the plate-shaped component 1 according to this embodiment further includes reinforcing members 41 and 42 that reinforce the plate-shaped portion 10. This configuration makes it possible to increase the strength of the plate-shaped portion 10.

[0103] Furthermore, the fixture with a tabletop 100 according to this embodiment comprises a tabletop, which is the plate-shaped component 1 described above, and a support structure 2 that supports the tabletop. This configuration makes it possible to realize a fixture with a tabletop 100 that can suppress any discomfort that may occur when a user touches it.

[0104] Furthermore, the manufacturing method of the plate-shaped part 1 according to this embodiment includes a preparation step S101 for preparing a plate-shaped part 10 made of metal having a first surface 11a, a second surface 11b located on the opposite side of the first surface 11a, and an outer peripheral edge 12, and a fixing part 20 having a fixing surface 21a, an outer surface 22a facing an intersecting direction that intersects with the orthogonal direction (up and down direction Z) perpendicular to the fixing surface 21a, and a connecting surface 24a connecting the fixing surface 21a and the outer surface 22a, a fixing step S102 for fixing the fixing surface 21a to the second surface 11b at the outer peripheral edge 12 so that a gap GP is created between the connecting surface 24a and the second surface 11b at the outer peripheral edge 12, and a bending step S103 for bending the outer peripheral edge 12 toward the connecting surface 24a to form a bent portion 15 on the outer peripheral edge 12 in which the first surface 11a constitutes a curved surface (first bent surface 15a). This configuration makes it possible to manufacture a plate-shaped component 1 that can suppress any discomfort that may occur when the user touches it.

[0105] Furthermore, in the preparation step S101, the plate-like portion 10 has an outer end surface 11c facing outward in the intersecting direction, and in the bending step S103, the outer peripheral edge 12 is bent toward the connecting surface 24a from a state where the outer end surface 11c of the plate-like portion 10 and the outer surface 22a of the fixing part 20 are on the same plane. With this configuration, at the end of the bending step S103, the difference in position between the outer end (the end facing outward in the intersecting direction) of the plate-like portion 10 and the outer surface 22a in the intersecting direction can be reduced.

[0106] (Second Embodiment) Next, a second embodiment will be described, but its basic configuration is the same as that of the first embodiment. Therefore, the same reference numerals are used for similar components, and their descriptions are omitted; only the differences will be described.

[0107] Figure 8 is a cross-sectional view showing a plate-shaped component 1A according to a second embodiment of the present invention. As shown in Figure 8, the plate-shaped part 1A according to this embodiment differs from the plate-shaped part 1 according to the first embodiment in the shape of the curved portion 12b (corner portion CN).

[0108] As shown in Figure 8, in the plate-shaped part 1A according to this embodiment, the entire second bent surface 15b of the bent portion 15 is in contact with the connecting surface 24a of the fixed part 20. Such a structure can be achieved by performing the bending process S103 described above so that the entire second bent surface 15b is in contact with the connecting surface 24a.

[0109] In this embodiment as well, a curved portion 12b (corner portion CN), which is part of the outer peripheral edge 12, is provided with a bent portion 15 in which the first surface 11a constitutes a curved surface (first bent surface 15a). Therefore, similar to the first embodiment, a plate-shaped component 1A that can suppress any discomfort that may occur when the user touches it can be realized.

[0110] (Third embodiment) Next, a third embodiment will be described, but its basic configuration is the same as that of the first embodiment. For this reason, the same reference numerals are used for similar components, and their descriptions are omitted; only the differences will be described.

[0111] Figure 9 is a cross-sectional view showing a plate-shaped component 1B according to a fourth embodiment of the present invention. As shown in Figure 9, the plate-shaped component 1B according to this embodiment differs from the plate-shaped component 1 according to the first embodiment in the shape of the connecting portion 24 and the connecting surface 24a.

[0112] As shown in Figure 9, the connecting portion 24 according to this embodiment has an L-shaped bend in a cross section parallel to the vertical direction Z. As a result, the connecting surface 24a includes a bent surface 24aA, a flat surface 24aB, a bent surface 24aC, a flat surface 24aD, and a bent surface 24aE.

[0113] The bent surface 24aA, the flat surface 24aB, the bent surface 24aC, the flat surface 24aD, and the bent surface 24aE are arranged in this order from the inner edge 24a1 to the outer edge 24a2. The bent surfaces 24aA, 24aC, and 24aE are curved surfaces formed as a result of the bending process of the connecting portion 24. In this connecting portion 24 as well, the outer edge 24a2 is located below the inner edge 24a1 and outward in the intersecting direction. As a result, the connecting surface 24a forms a step ST with respect to the fixed surface 21a in a direction away from the second surface 11b (i.e., downward).

[0114] In this embodiment as well, a curved portion 15 is provided on the curved portion 12b (corner portion CN), which is part of the outer peripheral edge 12, where the first surface 11a constitutes a curved surface (first bent surface 15a). Therefore, similar to the first embodiment, a plate-shaped component 1B can be realized that can suppress any discomfort that may occur when the user touches it.

[0115] (modified version) The technical scope of the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention.

[0116] For example, in the above embodiment, the bending process S103 was described as starting from a state where the outer end surface 11c of the plate-like portion 10 and the outer surface 22a of the fixing component 20 are on the same plane (see upper part of Figure 6), but this is not limited to this. That is, the bending process S103 may start from a state where the outer end surface 11c and the outer surface 22a are not on the same plane. In other words, in the fixing process S102, the fixing surface 21a of the fixing component 20 may be fixed to the second surface 11b of the plate-like portion 10 even if the second condition described above is not met.

[0117] In the example shown in the lower part of Figure 6, the entire bent portion 15 overlapped with the connecting surface 24a in a plan view, but the shape of the bent portion 15 is not limited to this. The bent portion 15 may protrude outward in the intersecting direction from the outer surface 22a of the fixing part 20. In this case, a part of the bent portion 15 will overlap with the connecting surface 24a in a plan view.

[0118] Furthermore, although the above embodiment described a case in which the plate-like portion 10 (outer peripheral edge portion 12) has four straight portions 12a and four curved portions 12b and has a rectangular shape in plan view, the shape of the plate-like portion 10 (outer peripheral edge portion 12) can be changed as appropriate. For example, the plate-like portion 10 (outer peripheral edge portion 12) may have a polygonal shape such as a triangle or a pentagon. In this case as well, by employing a filling portion FL as in the above embodiment in the curved portions 12b (corner portions CN) arranged between the straight portions 12a, the same effects and advantages as in the above embodiment can be obtained.

[0119] Furthermore, the painting process S104 is not required. In other words, the plate-shaped parts 1, 1A, and 1B do not need to have a coating 50.

[0120] Furthermore, the base material fixing step S105 is not required. That is, the plate-shaped parts 1, 1A, and 1B do not need to have a base material 30. In this case, the plate-shaped parts 1, 1A, and 1B do not have a second reinforcing member 52 and only have a first reinforcing member 41, and the first reinforcing member 41 may be fixed to the plate-shaped part 10 (second surface 11b).

[0121] Furthermore, without departing from the spirit of the present invention, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described embodiments and modifications may be combined as appropriate.
