[Technical Field]

[0001] The present invention relates to a picture frame case. [Background technology]

[0002] For example, when exhibiting artworks such as paintings in art galleries and museums, picture frames are sometimes used to protect the artworks, and viewers can view the artworks enclosed in transparent picture frames through the picture frames.

[0003] The techniques for picture frame cases are shown below. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2023-31314 Summary of the Invention [Problem to be solved by the invention]

[0005] However, when viewing artworks through a picture frame case, depending on the location of the picture frame case and the position of the lighting in the museum, the viewer's face may be reflected in the picture frame case, making it difficult to see the artwork.

[0006] Therefore, one disclosure provides a picture frame case that suppresses the obstruction of viewing due to reflections. [Means for solving the problem]

[0007] The top panel and four side panels form a rectangular parallelepiped with an open bottom, and the top panel and the four side panels are transparent acrylic panels. The outer surface of the top panel is a low-reflection surface with a light reflectance lower than a predetermined value. Exhibits can be placed and fixed in the space inside the rectangular parallelepiped, and the exhibits can be viewed through the top panel. [Effects of the Invention]

[0008] One disclosure reduces the disruption of viewing due to reflections. [Brief explanation of the drawings]

[0010] [First embodiment] A first embodiment will be described below. Fig. 1 is a diagram showing an example of the appearance of a picture frame case 1.

[0011] The picture frame case 1 is composed of a top panel 10 and four side panels 11 to 13. The picture frame case 1 has no bottom panel and forms a hollow rectangular parallelepiped. The hollow part inside has a mechanism that can fix an art object (exhibit) such as a painting.

[0012] The top panel 10 and the side panels 11 to 13 are acrylic panels with two wide sides and four narrow sides. The acrylic panels have, for example, an ultraviolet blocking function. The narrow sides may come into contact with other panels during welding, for example. Furthermore, the two wide sides may not come into contact with the wide sides of other panels during welding, but may come into contact with the four narrow sides. Furthermore, while the acrylic panels are transparent, the acrylic used for the side panels may be highly transparent, colored, or translucent.

[0013] The top panel 10 (top panel) has an upper surface (a surface visible from above) that is a low-reflection surface (shaded surface in FIG. 1) that is coated with a low-reflection coating or has a low-reflection film attached thereto. The low-reflection surface has, for example, a light reflectance that is suppressed to a predetermined value or less. Details of the low-reflection surface will be described later.

[0014] An example of how to use the picture frame case 1 will be described. For example, the picture frame case 1 is hung on a wall for display with a painting fixed inside. The picture frame case 1 has holes in the side panels 11 and 13 through which a device (such as a screw) for fixing the painting can be passed. When hung on a wall for display, the side panel 11 is positioned on the upper side and the side panel 13 is positioned on the lower side. When hung on a wall, the top panel 10 is the front side that a viewer views. The viewer views the painting stored in the picture frame case 1 from a distance of several tens of centimeters to several meters. In this case, because the outer side of the top panel 10, which is the front side, is a low-reflection surface, the viewer can view the painting with reduced reflection from the viewer's face and other exhibits.

[0015] 2 is a diagram showing an example of a six-sided drawing of a picture frame case 1 made by the side-opening method. The picture frame case 1 is made by the side-opening method, and the four narrow sides of the top panel 10 contact and are fixed to the inside of a rectangular frame made up of four side panels 11 to 13 (the wider sides of the side panels).

[0016] 2(A) is a plan view seen from above of the frame case 1. The low-reflection surface is the upper surface of the top panel 10. Therefore, the acrylic is exposed in the frame portion formed by the side panels 11 to 13.

[0017] FIG. 2(B) is a front view of the frame case 1 as seen from the front. The dotted line indicates the structure of the inside of the acrylic plate. The top panel 10 is in contact with the inside (wide surface) of the upper part of the side panel 11. Then, on the left and right sides of the side panel 11, side panels 12 and 14 are in contact with the side panels 11 and 13, respectively. In the front view, all of the acrylic is exposed, and there are no low-reflection surfaces. The rear view of the frame case 1 as seen from the rear has the same structure as the front view.

[0018] FIG. 2(C) is a right side view of the frame case 1 as viewed from the right lateral direction. The top panel 10 is in contact with the inside of the upper part of the side panel 12. The side panels 11 and 13 are in contact with the inside of the left and right sides (wide surfaces) of the side panel 12, respectively, in a recessed state with the side panels 12 and 14. In the right side view, all of the acrylic is exposed, and there are no low-reflection surfaces. The left side view of the frame case 1 as viewed from the left has the same configuration as the right side view.

[0019] The relationship between the side panels 11 to 13 is not limited to the example shown in Figure 2. It is sufficient that the side panels 11 to 13 can form a rectangular frame (rectangular cylindrical shape). Also, in the subsequent figures, the relationship between the side panels 11 to 13 is not limited to the example shown in the figure.

[0020] 3 is a diagram showing an example of a six-sided drawing of a picture frame case 1 made by the top surface opening method. Picture frame case 1 is made by the top surface opening method, and the wide surface of top panel 10 contacts and is fixed to the top of a rectangular cylindrical frame made up of four side panels 11 to 13 (the narrow surfaces of the side panels).

[0021] 3(A) is a plan view of the frame case 1 as seen from above. The low-reflection surface is the upper surface of the top panel 10. Only the top panel 10 is visible from above, and the frame portion made up of the side panels 11 to 13 is hidden by the wide surface of the top panel 10.

[0022] FIG. 3(B) is a front view of the frame case 1 as seen from the front. The top panel 10 is in contact with the outer upper part (narrow surface) of the side panel 11. Then, on the left and right sides of the side panel 11, the side panels 12 and 14 are in contact with the side panels 11 and 13, respectively. In the front view, all of the acrylic is exposed, and there are no low-reflection surfaces. The rear view of the frame case 1 as seen from the rear has the same configuration as the front view.

[0023] FIG. 3(C) is a right side view of the frame case 1 as viewed from the right lateral direction. The top panel 10 is in contact with the upper outer surface (narrow surface) of the side panel 12. The side panels 11 and 13 are in contact with the inner left and right sides of the side panel 12, respectively, in a recessed state against the side panels 12 and 14. In the right side view, all of the acrylic is exposed, and there are no low-reflection surfaces. The left side view of the frame case 1 as viewed from the left has the same configuration as the right side view.

[0024] [Second embodiment] A second embodiment will be described below. Fig. 4 is a diagram showing an example of the appearance of the frame case 1.

[0025] The frame case 1 is composed of a top panel 10 and four side panels 11 to 13. The frame case 1 has no bottom panel and forms a hollow rectangular parallelepiped. The external shape is the same as that of the first embodiment, for example.

[0026] The top panel 10 and the side panels 11-13 are plate-shaped acrylic panels consisting of two wide sides and four narrow sides. The narrow sides may come into contact with other panels during welding, for example. The two wide sides may not come into contact with the wide sides of other panels during welding, but may come into contact with the four narrow sides. The acrylic panels are transparent.

[0027] The top surface of the top panel 10 (the surface visible from above and outside) is a low-reflection surface (shaded surface in FIG. 4) on which a low-reflection coating is applied or a low-reflection film is attached.

[0028] The outer surfaces (surfaces visible from the front, rear, left and right directions) of the side panels 11 to 13 are low-reflection surfaces (shaded surfaces in FIG. 4) that are low-reflection coated or have low-reflection films attached thereto.

[0029] The method of using the frame case 1 is the same as, for example, the first embodiment.

[0030] 5 is a diagram showing an example of a six-sided drawing of a picture frame case 1 made by the side-opening manufacturing method. The picture frame case 1 is made by the side-opening manufacturing method, and the narrow side of the top panel 10 contacts and is fixed to the inside of a rectangular cylindrical frame made up of four side panels 11 to 13 (the wide side of the side panels).

[0031] 5(A) is a plan view seen from above of the frame case 1. The low-reflection surface is the upper surface of the top panel 10. Therefore, the acrylic is exposed in the frame portion formed by the side panels 11 to 13.

[0032] FIG. 5(B) is a front view of the frame case 1 as viewed from the front. The top panel 10 is in contact with the inside (wide surface) of the upper part of the side panel 11. The side panels 12 and 14 are in contact with the side panels 11 and 13 on the left and right sides of the side panel 11 in a non-reflective state. In the front view, the acrylic on the narrow surfaces of the side panels 12 and 14, which are not low-reflectivity surfaces, is exposed. The rear view of the frame case 1 as viewed from the rear has the same configuration as the front view.

[0033] FIG. 5(C) is a right side view of the frame case 1 as viewed from the right lateral direction. The top panel 10 is in contact with the inside of the upper part of the side panel 12. The side panels 11 and 13 are in contact with the inside of the left and right sides (wide surfaces) of the side panel 12, respectively, in a recessed state with the side panels 12 and 14. In the right side view, the wide external surface of the side panel 12 is exposed, and the entire surface is a low-reflection surface. The left side view of the frame case 1 as viewed from the left direction has the same configuration as the right side view.

[0034] 6 is a diagram showing an example of a six-sided drawing of a picture frame case 1 made by the top surface opening method. Picture frame case 1 is made by the top surface opening method, and the wide surface of top panel 10 contacts and is fixed to the top of a rectangular frame made up of four side panels 11 to 13 (the narrow surfaces of the side panels).

[0035] 6(A) is a plan view of the frame case 1 seen from above. The low-reflection surface is the upper surface of the top panel 10. Only the top panel 10 is visible from above, and the frame portion made up of the side panels 11 to 13 is hidden by the large surface of the top panel 10.

[0036] FIG. 6(B) is a front view of the frame case 1 as viewed from the front. The top panel 10 is in contact with the outer upper part (narrow surface) of the side panel 11. Then, on the left and right sides of the side panel 11, the side panels 12 and 14 are in contact with the side panels 11 and 13, respectively. In the front view, the acrylic on the narrow surfaces of the side panels 12 and 14, which are not low-reflectivity surfaces, is exposed. The rear view of the frame case 1 as viewed from the rear has the same configuration as the front view.

[0037] FIG. 6(C) is a right side view of the frame case 1 as viewed from the right lateral direction. The top panel 10 is in contact with the outer upper part (narrow surface) of the side panel 12. The side panels 11 and 13 are in contact with the inner left and right sides of the side panel 12, respectively, in a recessed state with the side panels 12 and 14. In the right side view, the outer wide surface of the side panel 12 is exposed, and the entire surface is a low-reflection surface. The left side view of the frame case 1 as viewed from the left has the same configuration as the right side view.

[0038] [Other embodiments] The low-reflection surface in the above examples is sufficient as long as it can suppress light reflection to a certain level, and there are no particular limitations on the low-reflection coating or low-reflection film. For example, a 3-millimeter-thick transparent acrylic plate has a reflectance of about 8% on both sides, while a low-reflection acrylic plate preferably has a reflectance of less than 2% on both sides.

[0039] Furthermore, the low-reflection surface is provided on one side of the plate, but may be provided on both sides, for example. Whether the low-reflection surface is provided on both sides or one side may be determined, for example, depending on the desired reflectance. [Explanation of symbols]
