Summary of the Invention

Problems to be Solved by the Invention

[0004] The present disclosure discloses an example of an exhibit holder capable of enhancing the entertainment value of an exhibit.

Means for Solving the Problems

[0005] The exhibit holder preferably includes at least one of the following components. That is, the component is a holding frame (30) disposed on the back surface of an exhibit (P) such as a painting or a photograph and holding the exhibit (P), and a light emitting portion (40) provided on the holding frame (30) and emitting light toward the back surface side of the holding frame (30).

[0006] Thereby, according to the exhibit holder, it is possible to enhance the entertainment value of the exhibit. Further, since the light emitting portion (40) emits light toward the back surface side, it is possible to indirectly illuminate the exhibit (P) with the light reflected by a wall or the like. Consequently, it becomes easier to obtain an illumination effect as compared with the case where the exhibit P is directly illuminated with light.

[0007] Incidentally, the symbols in each of the parentheses above are just examples showing the correspondence with the specific configurations etc. described in the embodiments described later, and this disclosure is not limited to the specific configurations etc. indicated by the symbols in the parentheses above.

[0009] The following "Embodiments of the Invention" are examples of embodiments that fall within the technical scope of this disclosure. In other words, the features defining the invention as described in the claims are not limited to the specific configurations and structures shown in the embodiments below.

[0010] The arrows and diagonal lines indicating direction in each figure are included to facilitate understanding of the relationships between the figures and the shapes of each component or part. Therefore, the inventions shown in this disclosure are not limited to the directions indicated in each figure. Diagonal lines do not necessarily indicate cross-sectional views.

[0011] At least one of the components or parts described with reference numerals is provided unless otherwise specified, such as "one." In other words, if there is no such specification, such as "one," there may be two or more such components. The exhibit holders shown in this disclosure comprise at least one of the components, such as the components or parts described with reference numerals, and the illustrated structural parts.

[0012] (First Embodiment) <1. Outline configuration of the exhibit holder> This embodiment applies an example of an exhibit holder according to the present disclosure to an exhibit holder for displaying flat exhibits with little or no unevenness, such as photographs and printed materials. As shown in Figure 1, the exhibit holder 1 includes an art frame 3 and a support arm 5, etc.

[0013] The art frame 3 is a component for holding a rectangular plate-shaped exhibit P. The support arm 5 is an arm-shaped support that supports the art frame 3. As shown in Figure 2, the support arm 5 according to this embodiment has a plurality of rotatable movable parts (joints) 5A, 5B.

[0014] Incidentally, the support arm 5 according to this embodiment conforms to standards determined by industry standardization organizations for video peripheral equipment. Specifically, the support arm 5 has a mounting structure that conforms to the so-called "VESA (Video Electronics Standards Association) standard".

[0015] In other words, in this embodiment, four screws (not shown) are used to fix the support arm 5 to the art frame 3, and the pitch dimension of these screws conforms to the VESA standard.

[0016] Note that the support arm 5 is provided with a mounting portion 5C (see FIG. 2) on the tip side and a fixing portion 5D (see FIG. 1) on the base side. The mounting portion 5C is a portion where the art frame 3 is mounted. The fixing portion 5D is a portion fixed to a structure such as a wall or a desk.

[0017] <Structure of the art frame> As shown in FIG. 3, the art frame 3 has at least a holding frame 30 and a light emitting portion 40. In addition to the holding frame 30 and the light emitting portion 40, the art frame 3 according to the present embodiment has a back plate 31, a mat 32, a surface cover 33, a frame 34, and the like.

[0018] <Holding frame> The holding frame 30 is disposed on the back surface of the exhibit P and is a member for holding the exhibit P. A mounting portion 30B is provided at substantially the center of the holding frame 30. The mounting portion 30B is a portion where the support arm 5 can be detachably mounted.

[0019] That is, the holding frame 30 is a dome-shaped member that bulges on the back side so as to cover the back side of the exhibit P (in this embodiment, the back plate 31). And at least one (a plurality in this embodiment) through holes 30A are provided in the holding frame 30.

[0020] Each through hole 30A is a hole that communicates the space existing between the holding frame 30 and the exhibit P (in this embodiment, the back plate 31) with the external space. Specifically, as shown in FIG. 4, the holding frame 30 has a mounting portion 30B, a spoke portion 30C, a frame portion 30D, and the like.

[0021] In this embodiment, a plurality of spoke portions 30C are provided. And each spoke portion 30C constitutes a leg portion that extends from the mounting portion 30B toward the outer edge side of the exhibit P (in this embodiment, the back plate 31). In this embodiment, the mounting portion 30B is in the shape of a rectangular plate, and each spoke portion 30C extends from each corner portion of the mounting portion 30B toward the outer edge side.

[0022] The frame portion 30D is an annular (in this embodiment, rectangular frame shape) member that connects the leading ends of the multiple spoke portions 30C in the direction of extension. The mounting portion 30B is offset to the rear side, or rearward side, relative to the frame portion 30D.

[0023] The retaining frame 30 according to this embodiment is made of glass fiber reinforced plastic or carbon fiber reinforced plastic. The mounting portion 30B, spoke portion 30C, and frame portion 30D are integrally molded from fiber reinforced plastic and are a single piece.

[0024] Therefore, a metal mount retainer 30E is integrated into the mounting portion 30B according to this embodiment. The mount retainer 30E is provided with a female threaded portion 30F into which the four screws are inserted.

[0025] <Light-emitting part> As shown in Figure 2, the light-emitting unit 40 is provided on the holding frame 30. The light-emitting unit 40 emits light toward the rear side of the holding frame 30, that is, toward the rear side of the art frame 3. In other words, the light-emitting unit 40 emits light toward the wall or the like at the base of the support arm 5.

[0026] The light-emitting section 40 according to this embodiment is a so-called "LED strip light" in which a large number of LEDs are arranged in series to form a strip (tape). The light-emitting section 40 is positioned on the back side of the frame section 30D so as to surround almost the entire circumference of the mounting section 30B.

[0027] <Backing board, mat, surface cover, and frame> In this embodiment, as shown in Figure 2, the frame portion 30D of the retaining frame 30 is fitted into the picture frame 34, and the retaining frame 30 and the picture frame 34 are fixed together with fasteners (also called "dragonflies") 34A.

[0028] As shown in Figure 3, the backing board 31, mat 32, and surface cover 33 are indirectly fixed to the holding frame 30 by being sandwiched between the frame portion 30D and the picture frame 34. Similarly, the exhibit P is indirectly fixed to the holding frame 30 by being sandwiched between the surface cover 33 and the backing board 31.

[0029] The surface cover 33 is a colorless, transparent plate-shaped material such as acrylic or glass. The back plate 31 is placed on the back of the exhibit P and fixed to the holding frame 30, thereby maintaining the position of the exhibit P.

[0030] As shown in Figure 5, a speaker 50 is provided on the back plate 31 according to this embodiment. Therefore, the speaker 50 according to this embodiment is indirectly attached to the holding frame 30. The mat 32 is a decorative panel that covers the outer edge of the exhibit P.

[0031] <3. Features of the exhibit holder according to this embodiment> The art frame 3 is provided with a mounting section 30B to which a support arm 5 can be detachably attached. This makes it possible to hold and display exhibits P using the exhibit holder 1, for example, by using a commercially available display arm as the support arm 5. Consequently, it becomes possible to diversify the display methods compared to conventional display methods that use hanging strings.

[0032] The art frame 3 is equipped with a light-emitting section 40 and a speaker 50. This allows the exhibit holder 1 according to this embodiment to enhance the entertainment value of the exhibit P.

[0033] In particular, since the light-emitting unit 40 emits light toward the rear, it is possible to indirectly illuminate the exhibit P with light reflected from a wall or the like. Consequently, compared to illuminating the exhibit P directly, the shadows of the exhibit P become more prominent, making it easier to obtain a lighting effect.

[0034] The retaining frame 30 according to this embodiment is a dome-shaped member that rises on the back side so as to cover the back side of the exhibit P. The retaining frame 30 is provided with at least one through hole 30A.

[0035] This can prevent heat from accumulating in the space between the holding frame 30 and the exhibit P, thereby preventing thermal damage to the exhibit P caused by the heat trapped in that space.

[0036] The retaining frame 30 according to this embodiment is made of glass fiber reinforced plastic or carbon fiber reinforced plastic. Therefore, it is possible to achieve a lightweight retaining frame 30 while ensuring high rigidity.

[0037] Incidentally, it is generally difficult to provide the female threaded portion into which the four screws mentioned above are inserted in the fiber-reinforced plastic mounting portion 30B. In contrast, in this embodiment, the metal mount retainer 30E is integrated into the mounting portion 30B. Therefore, it becomes possible to easily provide the female threaded portion 30F in the mounting portion 30B.

[0038] (Second Embodiment) <1. Overview of this embodiment> The exhibit holder 1 according to the above embodiment was an exhibit holder for displaying flat exhibits with almost no unevenness, such as photographs and printed materials. In contrast, the exhibit holder 1 according to this embodiment is an exhibit holder for exhibits P such as paintings on canvas, such as oil paintings.

[0039] As shown in Figure 6, a canvas consists of a canvas P2 stretched over a frame P1 made of wood or the like. Unlike photographs and prints, oil paintings have relatively large irregularities on their surface.

[0040] Therefore, it is not possible to employ a method of holding the exhibit P by sandwiching it between the back plate 31 and the front cover 33. Thus, in this embodiment, as shown in Figure 7, the exhibit P can be held to the holding frame 30 using at least one (multiple in this embodiment) fixing unit 60.

[0041] The following description concerns the differences between this embodiment and the exhibit holder according to the embodiment described above. Components identical to those in the embodiment described above are denoted by the same reference numerals. Therefore, redundant explanations are omitted in this embodiment.

[0042] <2. Configuration of the fixed unit> Each fixing unit 60, as shown in Figure 8, is composed of a movable contact portion 61, a fixed contact portion 62, a male threaded rod 63, a female threaded portion 64, and a loosening prevention portion 65, etc. The movable contact portion 61 is a member that can move toward and away from the frame P1.

[0043] The fixed contact portion 62 is a member fixedly positioned opposite the movable contact portion 61, with the frame P1 in between. The movable contact portion 61 presses against the inside of the frame P1, pushing the frame P1 towards the fixed contact portion 62, thereby clamping the frame P1.

[0044] Furthermore, cushion sheets 61A and 62A are provided on the portion of the movable contact portion 61 that contacts the frame P1, and on the portion of the fixed contact portion 62 that faces the frame P1. The cushion sheets 61A and 62A are made of hard rubber to prevent the frame P1 from shifting and to suppress damage to the frame P1.

[0045] The male threaded rod 63 is a rod-shaped male thread with a movable contact portion 61 provided at its tip. The movable contact portion 61 is rotatably connected to the male threaded rod 63 with its central axis L1 as the center of rotation. Therefore, even if the male threaded rod 63 rotates around the central axis L1, the movable contact portion 61 does not rotate.

[0046] The female threaded portion 64 is a component having a female threaded hole into which the male threaded rod 63 is inserted. The female threaded portion 64 and the fixing contact portion 62 are fixed to the back plate 31. In this embodiment, the fixing contact portion 62 and the female threaded portion 64 are a single piece made of metal or resin. The back plate 31 is made of a light metal plate, glass fiber reinforced plastic, or carbon fiber reinforced plastic.

[0047] The anti-loosening portion 65 restricts the rotation of the male threaded rod 63. In this embodiment, the anti-loosening portion 65 is a nut into which the male threaded rod 63 is inserted. In other words, the female threaded portion 64 and the anti-loosening portion 65 constitute a so-called "double nut structure," thereby restricting the rotation of the male threaded rod 63.

[0048] <3. Other components> As shown in Figure 7, cushion sheets 66 are placed on the backing board 31 at the four corners of the exhibit P (frame P1). Each cushion sheet 66 is a hard rubber sheet material that prevents the frame P1 from shifting and suppresses damage to the frame P1.

[0049] Openings 67 are provided in the back plate 31 in the parts corresponding to each male threaded rod 63 and each anti-loosening part 65. Each opening 67 is an operating window for the user to operate the male threaded rod 63 and the anti-loosening part 65.

[0050] As shown in Figure 9, the backing plate 31 is fixed to the frame portion 30D of the retaining frame 30 by bolts B1. In this embodiment, bolts B1 are placed at each of the four corners of the backing plate 31.

[0051] Each bolt B1 penetrates the frame 30D, the backing plate 31, and the surface cover 33 to reach the frame 34. That is, nuts (not shown) are embedded and fixed to the frame 34. As shown in Figure 7, cylindrical (in this embodiment, cylindrical) spacers 31A are placed at the four corners of the backing plate 31.

[0052] Spacer 31A is a component that secures a space (hereinafter referred to as the storage space) for storing the exhibit P between the back plate 31 and the front cover 33 (see Figure 6). Each bolt B1 passes through the inside of each spacer 31A and is fastened to the corresponding nut.

[0053] Therefore, the backing plate 31, the surface cover 33, and the frame 34 are fixed to the retaining frame 30. The left, right, top, and bottom of the storage space are covered by strip-shaped closing members 31B (see Figure 9).

[0054] In this embodiment, the closing member 31B is fitted into a groove (not shown) formed in the surface cover 33 and is adhesively fixed to the surface cover 33. Incidentally, it is desirable that the closing member 31B be made of a material that does not easily transmit ultraviolet light.

[0055] <3. Features of the exhibit holder according to this embodiment> In this embodiment, the movable contact portion 61 presses against the inside of the frame P1 to hold the exhibit P, so even exhibits P such as canvases can be easily held.

[0056] (Third embodiment) <1. Overview of this embodiment> In the second embodiment, the canvas (exhibit P) was held by sandwiching the frame P1 between a movable contact portion 61 and a fixed contact portion 62. In contrast, in the exhibit holder 1 according to this embodiment, the member corresponding to the movable contact portion 61 is made of an elastic material.

[0057] The following description concerns the differences between this embodiment and the exhibit holder according to the embodiment described above. Components identical to those in the embodiment described above are denoted by the same reference numerals. Therefore, redundant explanations are omitted in this embodiment.

[0058] In other words, as shown in Figure 10, in this embodiment, an elastic portion 68 is provided on the back plate 31. The elastic portion 68 is made of an elastically deformable member such as a hard sponge that can be pressed against the inside of the frame P1.

[0059] In other words, the elastic part 68 is fixed in a position on the backing plate 31 that allows it to be pressed against at least the inside of the frame P1. To put it another way, as shown in Figure 11, the elastic part 68 and the frame P1 come into contact with each other when the elastic part 68 is fitted inside the frame P1.

[0060] Furthermore, "pressing against the inside of the frame P1" means that the elastic part 68 and the frame P1 are in contact at the contact point between the elastic part 68 and the frame P1 in a state where sufficient contact pressure is generated to hold the exhibit P.

[0061] Incidentally, in this embodiment, a non-elastic portion 69 is provided in the area corresponding to the speaker 50. The non-elastic portion 69 is an area where no sponge or the like that forming the elastic portion 68 is provided. Also, the thickness dimension T1 of the elastic portion 68 is smaller than the thickness dimension T2 of the frame P1.

[0062] <2. Features of the exhibit holder according to this embodiment> In this embodiment, the elastic portion 68 presses against the inside of the frame P1 to hold the exhibit P, so even exhibits P such as canvases can be easily held.

[0063] (Other embodiments) The support arm 5 in the embodiment described above was a multi-jointed arm having a plurality of rotatable parts. However, the disclosure is not limited thereto. That is, for example, the support arm 5 in this embodiment may be a fixed support arm or support base that does not have joints.

[0064] In the embodiment described above, the anti-loosening portion 65 was a nut into which a male threaded rod 63 was inserted. However, the disclosure is not limited thereto. That is, the disclosure may also include, for example, a set screw as the anti-loosening portion.

[0065] The art frame 3 according to the above embodiment had a surface cover 33 and a frame 34. However, this disclosure is not limited thereto. That is, the disclosure may also include, for example, an art frame 3 in which the surface cover 33 and frame 34 are eliminated.

[0066] In the above-described embodiment, the bolt B1 was inserted from the retaining frame 30 side to the surface cover 33 side. However, this disclosure is not limited thereto. That is, the disclosure may also include, for example, a configuration in which the bolt B1 is inserted from the surface cover 33 side to the retaining frame 30 side.

[0067] The retaining frame 30 in the above-described embodiment was made of glass fiber reinforced plastic or carbon fiber reinforced plastic. However, this disclosure is not limited thereto. That is, the retaining frame 30 according to this disclosure may be made of a light metal such as aluminum or titanium, or an injection molded product of resin such as PE, ABS, PC-ABS, PP, or PS.

[0068] Furthermore, if the retaining frame 30 is made of a metal such as aluminum or titanium, the mounting retainer 30E may be omitted. When the retaining frame 30 is injection molded, the metal nut constituting the female thread portion may be insert molded. Alternatively, for example, a flat retaining frame 30 in which the through hole 30A is omitted may be used.

[0069] In the above-described embodiment, a speaker 50, a light-emitting unit 40, and a mounting unit 30B were provided. However, this disclosure is not limited thereto. That is, the disclosure may also include a configuration in which at least one of the speaker 50, light-emitting unit 40, and mounting unit 30B is omitted.

[0070] The speaker 50 in the above-described embodiment was of a type having a diaphragm. However, this disclosure is not limited thereto. That is, the disclosure may also include, for example, a speaker without a diaphragm, which uses another component (for example, a back plate 31) as a diaphragm.

[0071] In the embodiment described above, the speaker 50 was provided on the back plate 31. However, this disclosure is not limited thereto. That is, the disclosure may also include, for example, a configuration in which the speaker 50 is directly provided on the retaining frame 30.

[0072] The light-emitting unit 40 according to the embodiment described above was a so-called "LED strip light." However, this disclosure is not limited to this. That is, the disclosure may be, for example, a light with other configurations.

[0073] Furthermore, this disclosure is not limited to the embodiments described above, but is sufficient to be consistent with the intent of the disclosures described in the embodiments described above. Therefore, it may be a configuration in which at least two of the embodiments described above are combined, or a configuration in which any of the illustrated components or components described with reference numerals in the embodiments described above are omitted.
