[0009] Embodiments of the present invention will be described below with reference to the drawings. The various features shown in each embodiment below can be combined with each other. Furthermore, each feature constitutes an independent invention.

[0010] 1. Description of the configuration of panel 100 according to the embodiment The configuration of the panel 100 according to the embodiment will be described using Figures 1 to 9. As shown in Figure 1, the panel 100 comprises a design sheet member 1, a frame member 2, and a back panel portion 3. The panel 100 is a decorative panel installed on walls or the like in interior spaces such as hotels and residences. Each component will be described in order below.

[0011] 1-1. Composition of the design sheet member 1 The design sheet member 1 is a sheet-like member. The design sheet member 1 has a design surface portion 1A and an edge portion 1B. The constituent material of the design sheet member 1 is not particularly limited as long as it can be formed into a sheet and has shape retention properties that allow it to maintain a three-dimensional shape. Specifically, examples of materials for the design sheet member 1 include paper (such as Japanese paper), resin, silicone material, and metal material. As for metal materials, in addition to metal plates, mesh-like materials made by weaving metal wires can also be used. Furthermore, the design sheet member 1 may be composed of multiple sheet members stacked on top of each other. When multiple sheet members are stacked, different materials may be stacked, for example, paper and metal plates. Also, the constituent material of the design sheet member 1 may differ depending on the area of ​​the design sheet member 1, for example, the central part may be made of a metal material and the part surrounding the central part may be made of resin.

[0012] 1-1-1.Design surface part 1A The decorative surface portion 1A is a sheet-like portion formed to form a three-dimensional shape. The decorative surface portion 1A is positioned exposed on the front side of the panel 100 and is a part that adds design to the panel 100. Specifically, as shown in Figures 1 and 3, the decorative surface portion 1A has multiple ridges that protrude toward the front side and multiple valleys that are recessed toward the back side, formed by a geometric folding structure in which multiple polygons (for example, rhombuses or triangles) are combined. This folding structure not only serves as decoration but also functions as a structural material that increases the rigidity of the sheet member itself, thereby enabling even thin sheet materials to maintain a self-supporting three-dimensional shape. The shape of the decorative surface portion 1A is not limited to this and may be a dome shape mainly composed of curved surfaces, a wave shape, or an irregular wrinkled shape.

[0013] For example, as shown in FIG. 10, the design surface portion 1A may have a smooth undulation mainly composed of curves (surfaces). In FIG. 10, in order to clearly show the shape of the design surface portion 1A, the description of the frame member 2 and the like is omitted. However, in the form shown in FIG. 10, a configuration in which the design sheet member 1 is held by the frame member 2 can be adopted as in each of the above-described embodiments. At this time, the shape of the frame member 2 (for example, the end surface portions 2A3 and 2B3 and the roof portion 2B2 described later) becomes a shape corresponding to the three-dimensional undulation (including a curved shape as shown in FIG. 10) at the peripheral edge of the design surface portion 1A.

[0014] 1-1-2. Edge portion 1B The edge portion 1B is a sheet-like portion connected to the design surface portion 1A. The edge portion 1B extends from the outer peripheral edge of the design surface portion 1A and is a portion held by the frame member 2.

[0015] As shown in FIGS. 8 and 9, in the present embodiment, the edge portion 1B has a first portion 1B1 that extends, for example, substantially horizontally from the outer peripheral edge of the design surface portion 1A, and a second portion 1B2 that bends, for example, substantially vertically further toward the back side from the end of the first portion 1B1. This two-stage bending structure realizes both "clamping in the thickness direction with respect to the first portion 1B1" and "preventing slipping in the surface direction with respect to the second portion 1B2" by the frame member 2.

[0016] The first portion 1B1 is a portion sandwiched between the step portion 2A2 of the inner frame portion 2A and the roof portion 2B2 of the outer frame portion 2B. The second portion 1B2 is a portion located on the outer peripheral side of the first portion 1B1 and is a portion disposed between the outer surface 2A5 of the inner frame portion 2A and the inner surface 2B4 of the outer frame portion 2B.

[0017] 1-2. Configuration of the frame member 2 The frame member 2 is a member for holding the design sheet member 1. As shown in FIGS. 1 to 3, the frame member 2 has an inner frame portion 2A and an outer frame portion 2B. The inner frame portion 2A is arranged so as to surround the design surface portion 1A. The outer frame portion 2B is arranged outside the inner frame portion 2A so as to surround the inner frame portion 2A. The inner frame portion 2A and the outer frame portion 2B are engaged with each other in a state where the edge portion 1B is inserted between the inner frame portion 2A and the outer frame portion 2B so that the design sheet member 1 is held by the frame member 2. Specifically, as shown in FIGS. 6A to 7B, the inner frame portion 2A is inserted into the inner peripheral side of the outer frame portion 2B from the back side, whereby the two are integrated.

[0018] The constituent material of the frame member 2 (the inner frame portion 2A and the outer frame portion 2B) is not particularly limited as long as it has the rigidity and shape retention ability to hold the design sheet member 1. Specifically, as the material of the frame member 2, for example, a resin material, a metal material, wood (including processed wood such as MDF), a paper material (such as hard paper or reinforced cardboard), or a composite material combining these can be adopted. Specifically, as the resin material, for example, general-purpose resins such as ABS, polycarbonate (PC), polyethylene (PE), polypropylene (PP), polystyrene (PS), and engineering plastics can be adopted. Since the resin material is excellent in moldability, it is suitable for accurately mass-producing complex cross-sectional shapes such as the step portion 2A2, the roof portion 2B2, and the engaging portion 2B6 described later. Also, as the metal material, specifically, for example, aluminum, stainless steel, iron, brass, etc. can be used. Also, the constituent material of the inner frame portion 2A and the constituent material of the outer frame portion 2B may be the same or different.

[0019] 1-2-1. Inner frame portion 2A As shown in FIGS. 4A and 4B, the inner frame portion 2A has an inner frame portion main body 2A1, a step portion 2A2, an end surface portion 2A3, an inner side surface 2A4, and an outer side surface 2A5.

[0020] The inner frame body 2A1 is a plate-like member that constitutes the main part of the inner frame 2A, and is formed in a frame shape so as to surround the design surface 1A. In one example of the embodiment, the shape of the inner frame body 2A1 is described as having four sides (forming a quadrilateral), but it is not limited to this, and may have three sides (forming a triangle) or five sides (forming a polygon with five or more corners). Furthermore, the shape of the inner frame body 2A1 is not limited to a polygon, and may be a curved frame shape such as a circle or an ellipse.

[0021] The stepped portion 2A2 is a stepped portion provided on the inner frame body 2A1. In one embodiment, more specifically, as shown in Figures 4B and 9, the stepped portion 2A2 is formed at the upper end of the inner frame body 2A1, with a roughly L-shaped cross-section that slopes downwards toward the outside. The stepped portion 2A2 is provided at a position opposite the roof portion 2B2 of the outer frame 2B. As shown in Figure 9, the edge portion 1B (specifically the first portion 1B1) is sandwiched between the roof portion 2B2 and the stepped portion 2A2. In other words, as shown in Figures 6A to 7B, when the inner frame 2A is inserted into the outer frame 2B from the rear side, the first portion 1B1 of the design sheet member 1 is sandwiched in close contact between the stepped portion 2A2 and the roof portion 2B2 of the outer frame 2B, which will be described later. In other words, when the inner frame portion 2A is inserted into the outer frame portion 2B, the upper surface (flat surface) of the stepped portion 2A2 and the lower surface of the roof portion 2B2 face each other with a gap corresponding to the thickness of the design sheet member 1, and the first portion 1B1 is firmly held in place in the thickness direction.

[0022] The end face portion 2A3 is the portion of the end face corresponding to the front side of the panel 100. In this embodiment, the end face portion 2A3 constitutes the upper surface of the portion where the stepped portion 2A2 is formed. The end face portion 2A3 is formed to conform to the three-dimensional shape of the design surface portion 1A. This suppresses the occurrence of gaps (lifting of the design sheet member 1) between the inner frame portion 2A and the design surface portion 1A, thereby improving the appearance quality of the panel 100. As shown in Figures 4A and 4B, the end face portion 2A3 has a zigzag (wavy) contour along the circumferential direction of the frame member 2, with continuously changing height differences, so as to follow the complex three-dimensional shape (ridges and valleys) of the design surface portion 1A. When this end face portion 2A3 abuts against the back surface of the design sheet member 1, it functions as a support seat that supports the design sheet member 1 from the back side. This allows the design sheet member 1 to be held down with a uniform load around the entire circumference of the edge, making it possible to stably hold it without compromising its three-dimensional shape.

[0023] The inner surface 2A4 is the inner circumferential side surface of the inner frame portion 2A. The outer surface 2A5 is the outer circumferential side surface of the inner frame portion 2A. As shown in Figure 9, the outer surface 2A5 faces the inner surface 2B4 of the outer frame portion 2B, and a small gap can be formed between them to accommodate the second portion 1B2 of the edge portion 1B. Insertion into this gap provides resistance to pulling out in the planar direction (horizontal direction) of the design sheet member 1. The outer surface 2A5 of the inner frame portion 2A and the inner surface 2B4 of the outer frame portion 2B may be further firmly connected by adhesive and / or connecting members (not shown). Specifically, various fasteners such as rivets, hook-and-loop fasteners, screws, bolts, and nuts can be used as connecting members. Furthermore, the connecting member may be a connecting structure in which engaging parts are provided on the outer surface 2A5 of the inner frame portion 2A and the inner surface 2B4 of the outer frame portion 2B, respectively, and have a shape that allows them to engage with each other (for example, claws together, or a combination of recesses and protrusions).

[0024] 1-2-2. Outer frame section 2B As shown in Figures 5A and 5B, the outer frame portion 2B includes the outer frame body 2B1, the roof portion 2B2, the end face portion 2B3, the inner surface portion 2B4, the outer surface portion 2B5, and the engaging portion 2B6.

[0025] The outer frame body 2B1 is a plate-like member that constitutes the main part of the outer frame 2B, and is formed in a frame shape so as to surround the inner frame 2A. The outer frame body 2B1 has a shape that corresponds to the shape of the inner frame body 2A1. In other words, since the inner frame body 2A1 has a shape with four sides (forming a quadrilateral) in one example of the embodiment, the outer frame body 2B1 also has a shape with four sides (forming a quadrilateral).

[0026] The roof section 2B2 is connected to the outer frame body 2B1 and is provided to protrude from the outer frame body 2B1 side to the inner frame section 2A side. In other words, the roof section 2B2 is configured as an overhang-like portion that extends inward from the upper end of the outer frame body 2B1. As shown in Figure 9, the edge section 1B (specifically the first section 1B1) is sandwiched between the roof section 2B2 and the inner frame section 2A (specifically the stepped section 2A2).

[0027] The roof portion 2B2 is not limited to the shape of this embodiment, and various variations can be adopted. For example, as shown in Figure 5A, the roof portion 2B2 may be formed continuously around the entire circumference of the frame, or it may be formed intermittently (for example, in a comb-like shape). Also, the protruding length (width) of the roof portion 2B2 does not need to be constant, and may vary locally depending on the undulations of the design surface portion 1A and the shape of the edge portion 1B.

[0028] The surface (bottom surface) of the roof portion 2B2 facing the edge portion 1B may be provided with a microstructure to enhance the holding force of the edge portion 1B. Specifically, the bottom surface may be provided with protrusions that bite into the edge portion 1B, multiple ribs, or a rough surface finish (such as a textured finish). This is expected to more effectively prevent the edge portion 1B from being pulled out of the frame member 2 even when tension is applied to the design sheet member 1.

[0029] Furthermore, the cross-sectional shape of the roof portion 2B2 is not limited to the shape shown in Figure 9. For example, it may have a tapered shape in which the thickness gradually decreases toward the inside. In this case, it becomes easier to impart appropriate elasticity to the roof portion 2B2, and a stable pressing force can be applied. In addition, the tip of the roof portion 2B2 may have a claw-like shape that is slightly bent toward the back side (step portion 2A2 side) so as to bite into the design sheet member 1.

[0030] The end face portion 2B3 is the end face portion corresponding to the front side of the panel 100. Like the end face portion 2A3, the end face portion 2B3 is formed to conform to the three-dimensional shape of the design surface portion 1A. Specifically, as shown in Figure 5B, the end face portion 2B3 constitutes the upper surface of the roof portion 2B2 and has a three-dimensional height difference that matches the undulations of the design surface portion 1A. This makes it easier to make the shape of the design surface portion 1A continuous with the edge of the frame member 2 when viewed from the front, thereby improving the sense of design unity.

[0031] The inner surface 2B4 is the inner circumferential side of the outer frame 2B. The inner surface 2B4 is positioned opposite the outer surface 2A5 of the inner frame 2A. The outer surface 2B5 is the outer circumferential side of the outer frame 2B.

[0032] The engaging portion 2B6 is a part for holding the rear panel portion 3. The engaging portion 2B6 is configured to engage with the surface of the rear panel portion 3. The engaging portion 2B6 is formed at multiple locations along the circumferential direction of the frame so as to protrude further inward from the inner circumferential surface (inner surface 2B4) of the outer frame portion body 2B1. In one example of the embodiment, the position where the engaging portion 2B6 is provided is on the lower side (rear panel portion 3 side) of the inner circumferential surface (inner surface 2B4) of the outer frame portion body 2B1, but it is not limited to this. By having the engaging portion 2B6 in the outer frame portion 2B, it is possible to prevent the rear panel portion 3 from falling off and to avoid exposing the internal space, as well as to prevent the inner frame portion 2A from coming off the outer frame portion 2B, and consequently, it is expected that the clamping force between the roof portion 2B2 and the stepped portion 2A2 will be maintained.

[0033] 1-3. Configuration of the rear panel section 3, etc. The rear panel portion 3 is a component attached to the frame member 2 on the rear side of the panel 100. As shown in Figure 2, the rear panel portion 3 is engaged and held by the engaging portion 2B6 of the outer frame portion 2B. The material of the rear panel portion 3 is not particularly limited, but examples include resin, wood, metal, etc.

[0034] As shown in Figure 3, there may be a cavity between the design sheet member 1 and the back panel portion 3. In this case, the weight of the panel 100 can be reduced.

[0035] Furthermore, a functional member may be provided between the design sheet member 1 and the back panel portion 3. Examples of functional members include lighting members, heat insulating materials, sound absorbing materials, and reinforcing materials. If a lighting member is provided, the design of the design sheet member 1 can be enhanced by illuminating it from the back side.

[0036] 2. Manufacturing method of panel 100 according to the embodiment Next, a manufacturing method for the panel 100 according to this embodiment will be described with reference to Figures 6 to 9. The manufacturing method according to this embodiment comprises a molding step and a frame mounting step.

[0037] 2-1. Molding process In the molding process, the sheet material is molded into a desired three-dimensional shape. The molding method can be appropriately selected depending on the material of the design sheet material 1. The molding process forms a three-dimensional shape corresponding to the design surface portion 1A.

[0038] 2-2. Frame Installation Process In the frame mounting process, the frame member 2 holds the design sheet member 1 by engaging the inner frame member 2A and the outer frame member 2B with the edge portion 1B inserted between the inner frame member 2A and the outer frame member 2B.

[0039] Specifically, first, as shown in Figures 6A and 6B, the outer frame portion 2B is placed outside the inner frame portion 2A. At this time, the design sheet member 1 is positioned so that the edge portion 1B is located between the inner frame portion 2A and the outer frame portion 2B (the design sheet member 1 is not shown in Figures 6A and 6B).

[0040] Next, as shown in Figure 8, the relative distance between the inner frame 2A and the outer frame 2B is reduced. At this point, the first portion 1B1 of the edge 1B is just about to be sandwiched between the stepped portion 2A2 of the inner frame 2A and the roof portion 2B2 of the outer frame 2B.

[0041] Then, as shown in Figures 7A, 7B, and 9, the relative distance between the inner frame portion 2A and the outer frame portion 2B is further reduced, causing the inner frame portion 2A and the outer frame portion 2B to engage. In one embodiment, the engagement of the inner frame portion 2A and the outer frame portion 2B is achieved when the inner frame portion 2A is inserted inside the outer frame portion 2B, causing the engaging portion 2B6 of the outer frame portion 2B to engage with the lower edge portion 2A11 (see Figure 4B) of the inner frame portion body 2A1 of the inner frame portion 2A. As a result, the first portion 1B1 of the edge portion 1B is sandwiched between the roof portion 2B2 and the stepped portion 2A2, and the design sheet member 1 is held by the frame member 2.

[0042] Furthermore, after the frame installation process, the outer surface 2A5 of the inner frame portion 2A and the inner surface 2B4 of the outer frame portion 2B may be connected by adhesive and / or connecting members, if necessary.

[0043] 3. Description of the operation and effects according to the embodiment (1) The panel 100 according to this embodiment comprises a sheet-like design sheet member 1 and a frame member 2. The design sheet member 1 has a design surface portion 1A formed to have a three-dimensional shape and an edge portion 1B connected to the design surface portion 1A. The frame member 2 has an inner frame portion 2A arranged to surround the design surface portion 1A and an outer frame portion 2B arranged outside the inner frame portion 2A to surround the inner frame portion 2A. The inner frame portion 2A and the outer frame portion 2B are engaged with each other with the edge portion 1B inserted between the inner frame portion 2A and the outer frame portion 2B so that the design sheet member 1 is held by the frame member 2. With this configuration, the design sheet member 1 having a three-dimensional shape can be stably held by the frame member 2. Conventionally, when using a sheet-like member having a three-dimensional shape for decorative purposes such as interior decoration, it has been difficult to stably hold and decorate the member. In contrast, according to this embodiment, by adopting a structure in which the edge portion 1B is inserted and engaged between the inner frame portion 2A and the outer frame portion 2B, even a design sheet member 1 having a three-dimensional shape can be stably held by the frame member 2. Furthermore, the presence of the frame member 2 increases the rigidity of the panel 100, making it easier to install on walls and the like. Moreover, because the frame member 2 surrounds the outer periphery of the design sheet member 1, the three-dimensional shape of the design surface portion 1A is highlighted, enhancing the overall design appeal of the panel 100.

[0044] (2) In this embodiment, the outer frame portion 2B has an outer frame body 2B1 and a roof portion 2B2. The outer frame body 2B1 is arranged to surround the inner frame portion 2A. The roof portion 2B2 is connected to the outer frame body 2B1 and is provided to protrude from the outer frame body 2B1 side to the inner frame portion 2A side. The edge portion 1B is sandwiched between the roof portion 2B2 and the inner frame portion 2A. With this configuration, the roof portion 2B2 protrudes towards the inner frame portion 2A, allowing the edge portion 1B to be sandwiched between the roof portion 2B2 and the inner frame portion 2A. This makes it possible to hold the edge portion 1B more securely and effectively prevent the design sheet member 1 from falling off the frame member 2.

[0045] (3) In this embodiment, the inner frame portion 2A has a stepped portion 2A2. The stepped portion 2A2 is provided at a position opposite to the roof portion 2B2 of the outer frame portion 2B. The edge portion 1B is sandwiched between the roof portion 2B2 and the stepped portion 2A2. With this configuration, the edge portion 1B is sandwiched between the roof portion 2B2 and the stepped portion 2A2, which are opposing portions, so the edge portion 1B can be held more securely. In addition, by providing the stepped portion 2A2, the position in which the edge portion 1B is sandwiched is clearly defined, making it easier to position the design sheet member 1.

[0046] (4) In this embodiment, the inner frame portion 2A and the outer frame portion 2B each have end faces 2A3 and 2B3 corresponding to the front side of the panel 100. Each end face portion 2A3 and 2B3 is formed to conform to the three-dimensional shape of the design surface portion 1A. With this configuration, gaps between the end faces 2A3 and 2B3 of the frame member 2 and the design surface portion 1A are suppressed. This improves the appearance quality of the panel 100. In addition, because the end faces 2A3 and 2B3 conform to the three-dimensional shape of the design surface portion 1A, a sense of unity is created between the frame member 2 and the design surface portion 1A, enhancing the overall aesthetic appeal of the panel 100.

[0047] (5) In this embodiment, the design sheet member 1 may be composed of multiple sheet members stacked on top of each other. Such a configuration allows for a variety of design characteristics to be given to the design sheet member 1. For example, by stacking sheet members having different colors and textures, a unique visual effect that cannot be obtained with a single sheet member can be realized. Furthermore, by stacking different materials, a design sheet member 1 can be obtained that combines the characteristics of each material.

[0048] (6) In this embodiment, a rear panel portion 3 is further provided. The rear panel portion 3 is attached to the frame member 2 on the rear side of the panel 100. The space between the design sheet member 1 and the rear panel portion 3 may be hollow. With this configuration, the rear panel portion 3 can protect the rear side of the design sheet member 1. In addition, by creating a hollow space between the design sheet member 1 and the rear panel portion 3, the weight of the panel 100 can be reduced. If the panel 100 is lightweight, installation work on walls and the like becomes easier, and the load on the wall is also reduced.

[0049] (7) In this embodiment, a functional member may be provided between the design sheet member 1 and the back panel portion 3. With such a configuration, the panel 100 can be given additional functions by the functional member. For example, if a lighting member is provided as a functional member, illuminating the design sheet member 1 from the back side will emphasize the three-dimensional shape of the design surface portion 1A through the contrast of light and shadow, further enhancing the design appeal of the design sheet member 1. Also, if a heat insulating material or a sound absorbing material is provided as a functional member, the panel 100 can be given heat insulating performance or sound absorbing performance.

[0050] (8) In this embodiment, the outer surface 2A5 of the inner frame portion 2A and the inner surface 2B4 of the outer frame portion 2B may be connected by an adhesive and / or a connecting member. With this configuration, the engagement between the inner frame portion 2A and the outer frame portion 2B becomes stronger. As a result, even with long-term use of the panel 100, loosening between the inner frame portion 2A and the outer frame portion 2B can be suppressed, and the design sheet member 1 can be held stably over a long period of time.

[0051] (9) The manufacturing method according to this embodiment includes a frame mounting step. In the frame mounting step, the frame member 2 holds the design sheet member 1 by engaging the inner frame portion 2A and the outer frame portion 2B with the edge portion 1B inserted between the inner frame portion 2A and the outer frame portion 2B.
