[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0012] First, the overall configuration of the acrylic stand 10 according to this embodiment will be described with reference to Figs. 1(a), (b), 2, and 3(a), (b). Figs. 1(a) and (b) are configuration diagrams showing the acrylic stand 10 in an open state (open state), Fig. 1(a) is a diagram showing the inner side of the acrylic stand 10, and Fig. 1(b) is a diagram showing the outer side of the acrylic stand 10. Fig. 2 is a configuration diagram showing the acrylic stand 10 in a closed state (closed state). Figs. 3(a) and (b) are configuration diagrams of the main body 20 of the acrylic stand 10. The acrylic stand 10 of this embodiment is configured to include a main body 20 and a base 30 on which the main body 20 can be placed.

[0013] First, the main body 20 of the acrylic stand 10 will be described. The main body 20 is configured to include a first acrylic plate 21, a second acrylic plate 22, a third acrylic plate 23, a first connecting portion 24, and a second connecting portion 25. The main body 20 can be placed (installed without being fixed) on the base 30 in a closed state (closed state) as shown in Fig. 2, and can also be placed on the base 30 in an open state (open state) as shown in Figs. 1(a) and (b).

[0014] The first acrylic plate 21 is, for example, a substantially rectangular shape with a width of 63 mm × height of 89 mm (approximately B8 size: 64 × 91 mm) and a thickness of 3 mm. The first acrylic plate 21 has an outer surface (first surface) 51 and an inner surface (second surface) 52 opposite to the outer surface 51. As shown in FIG. 2, the outer surface 51 corresponds to the front cover surface when the user views the acrylic stand 10 in a closed state, and for example, a character design, a book title, an author name, etc. are drawn in 4C colors on a white background. As shown in FIG. 1(a), the inner surface 52 corresponds to the right side paper surface when the user views the acrylic stand 10 in an open state, and for example, vertically written text and page numbers, etc. are drawn in monochrome on a white background.

[0015] The second acrylic plate 22 has the same size and thickness as the first acrylic plate 21, and has an outer surface (third surface) 53 and an inner surface (fourth surface) 54 opposite to the outer surface 53, similar to the first acrylic plate 21. The outer surface 53 corresponds to the back cover surface when the user views the acrylic stand 10 in a closed state, and for example, a book JAN code (two-line barcode) and horizontally written text are drawn in 4C color on a white background (see FIG. 3(b)). In addition, the outer surface 53 may have a character design or the like drawn lightly. The inner surface 54 corresponds to the left side paper surface when the user views the acrylic stand 10 in an open state, as shown in FIG. 1(a), and for example, a character design is drawn in monochrome on a white background. In this way, the user can view the outer surfaces 51 and 53 in the closed state, and can view the inner surfaces 52 and 54 in the open state. In addition, when the main body 20 is closed, the main body 20 may be placed on the base 30 so that the outer surface 51 of the first acrylic plate 21 corresponds to the back cover surface and the outer surface 53 of the second acrylic plate 22 corresponds to the front cover surface.

[0016] The third acrylic plate 23 is, for example, a substantially rectangular shape with a width of 13 mm, a length of 89 mm, and a thickness of 3 mm. The third acrylic plate 23 has a back surface (fifth surface) 55. As shown in FIG. 2, the back surface 55 corresponds to the spine surface when the user views the acrylic stand 10 in a closed state so that the inner surface 52 of the first acrylic plate 21 and the inner surface 54 of the second acrylic plate 22 face each other, and for example, the title of the book, the author's name, the publisher's name, etc. are written vertically. In this embodiment, the title of the book, etc. is printed in 4C color on the inner surface of the back surface 55 (the surface closer to the first acrylic plate 21 and the second acrylic plate 22), and a white background is printed on the printing, but the title of the book, etc. may be printed on the outer surface of the back surface 55 (the surface farther from the first acrylic plate 21 and the second acrylic plate 22).

[0017] The first connecting part 24 is provided on the upper part of the main body 20, and is a connecting member that connects the first acrylic plate 21, the second acrylic plate 22, and the third acrylic plate 23. The first connecting part 24 is made of an acrylic plate, for example, like the first acrylic plate 21 and the second acrylic plate 22, and is a substantially square shape of 13 mm wide × 13 mm long and 3 mm thick.

[0018] The second connecting portion 25 is provided at the bottom of the main body 20, and is a connecting member that connects the first acrylic plate 21, the second acrylic plate 22, and the third acrylic plate 23. The second connecting portion 25 is made of, for example, an acrylic plate, and is a substantially rectangular shape of 19 mm wide x 13 mm long and 3 mm thick. The second connecting portion 25 is provided with a cutout portion (limiting portion) for limiting the angle at which the main body 20 opens, that is, the angle between the first acrylic plate 21 and the second acrylic plate 22 (see FIG. 5(b)). The first connecting portion 24 and the second connecting portion 25 form a biaxial hinge that holds the first acrylic plate 21 and the second acrylic plate 22 relatively rotatably (openable and closable). The detailed configurations and functions of the first connecting portion 24 and the second connecting portion 25 will be described later.

[0019] Next, the base 30 of the acrylic stand 10 will be described with reference to FIGS. 6 and 7. FIG. 6 is a configuration diagram of the base 30. FIG. 7 is an exploded view of the base 30. As shown in FIGS. 6 and 7, the base 30 is configured to include a first holding portion 31, a second holding portion 32, and a seat portion 33. The first holding portion 31 and the second holding portion 32 are each made of, for example, a transparent acrylic plate, and are mountain-shaped with a height of 47 mm and a base length of 37 mm. The seat portion 33 is made of, for example, a transparent acrylic plate, and is substantially elliptical with a major axis of 60 mm and a minor axis of 50 mm. The thickness of the acrylic plate constituting each of the first holding portion 31, the second holding portion 32, and the seat portion 33 is, for example, 3 mm. In this embodiment, the arrangement interval between the first holding portion 31 and the second holding portion 32 is set to be wider than the width of the third acrylic plate 23. This makes it possible to avoid interference between the third acrylic plate 23 and the first holding part 31 and the second holding part 32 when the main body part 20 is placed on the base part 30 in the open state as shown in Figure 1 (b) (the third acrylic plate 23 can be inserted between the first holding part 31 and the second holding part 32).

[0020] The first holding portion 31 has an attachment portion 311 configured to be insertable into a hole 331 formed in the seating portion 33. Similarly, the second holding portion 32 has an attachment portion 321 configured to be insertable into a hole 332 formed in the seating portion 33. The first holding portion 31 and the second holding portion 32 are fixed to the seating portion 33 by inserting the attachment portions 311, 321 into the holes 331, 332 formed in the seating portion 33.

[0021] The first holding part 31 has inclined parts 312 and 313 for holding the main body part 20. Similarly, the second holding part 32 has inclined parts 322 and 323 for holding the main body part 20. When the main body part 20 is placed on the base part 30 in an open state as shown in Figs. 1(a) and 1(b), the inclined part 312 of the first holding part 31 holds the outer surface 51 of the first acrylic plate 21, and the inclined part 313 of the first holding part 31 holds the bottom surface of the first acrylic plate 21. In this case, the inclined part 322 of the second holding part 32 holds the outer surface 53 of the second acrylic plate 22, and the inclined part 323 of the second holding part 32 holds the bottom surface of the second acrylic plate 22. By providing the inclined portions 312, 313, 322, and 323, when the main body portion 20 is in an open state, the main body portion 20 is placed on the base portion 30 so as to be inclined rather than vertical.

[0022] On the other hand, when the main body 20 is placed on the base 30 in a closed state as shown in FIG. 2, the outer surface 53 of the second acrylic plate 22 is held by the inclined portion 312 of the first holding portion 31 and the inclined portion 322 of the second holding portion 32, and the bottom surface of the first acrylic plate 21 and the bottom surface of the second acrylic plate 22 are held by the inclined portion 313 of the first holding portion 31 and the inclined portion 323 of the second holding portion 32. By providing the inclined portions 312, 313, 322, and 323, the main body 20 is placed on the base 30 so that it is inclined rather than vertical when the main body 20 is closed. Thus, in this embodiment, the main body 20 can be placed on the base 30 in a state where the first acrylic plate 21 and the second acrylic plate 22 are closed and in a state where the first acrylic plate 21 and the second acrylic plate 22 are opened.

[0023] Next, a mechanism for opening and closing the main body 20 will be described with reference to FIG. 4. FIG. 4 is an exploded view of the main body 20. The upper side of the first acrylic plate 21 is provided with a recess 213 and a protrusion (first protrusion) 211 adjacent to the recess 213 at the upper right when viewed from the outer surface 51. The upper side of the first acrylic plate 21 is provided with a rounded corner at the upper left when viewed from the outer surface 51. Similarly, the lower side of the first acrylic plate 21 is provided with a recess 214 and a protrusion (third protrusion) 212 adjacent to the recess 214 at the lower right when viewed from the outer surface 51. The lower side of the first acrylic plate 21 is provided with a rounded corner at the lower left when viewed from the outer surface 51. The upper side of the second acrylic plate 22 is provided with a recess 223 and a protrusion (second protrusion) 221 adjacent to the recess 223 at the upper left when viewed from the outer surface 53. In addition, the upper edge of the second acrylic plate 22 is rounded at the upper right when viewed from the outer surface 53 to form a corner R. Similarly, the lower edge of the second acrylic plate 22 is provided with a recess 224 and a convex portion (fourth convex portion) 222 adjacent to the recess 224 at the lower left when viewed from the outer surface 53. The lower edge of the second acrylic plate 22 is rounded at the lower right when viewed from the outer surface 53 to form a corner R. The upper center of the third acrylic plate 23 is provided with a convex portion 231. Similarly, the lower center of the third acrylic plate 23 is provided with a convex portion 232. In this embodiment, the first acrylic plate 21 and the second acrylic plate 22 are rounded at four corners to form the corner R, so that the user can safely handle the acrylic stand 10, but it is not essential to form the corner R.

[0024] The first connecting portion 24 is formed with a circular hole portion (first hole portion) 241, a circular hole portion (second hole portion) 242, and a rectangular hole portion 243. The convex portion 211 of the first acrylic plate 21 is rotatably inserted into the hole portion 241 of the first connecting portion 24. The convex portion 221 of the second acrylic plate 22 is rotatably inserted into the hole portion 242 of the first connecting portion 24. The convex portion 231 of the third acrylic plate 23 is inserted into the hole portion 243 of the first connecting portion 24. Since the hole portion 243 is rectangular, the convex portion 231 of the third acrylic plate 23 is not rotatable with respect to the first connecting portion 24.

[0025] The second connecting portion 25 is formed with a circular hole portion (third hole portion) 251, a circular hole portion (fourth hole portion) 252, and a rectangular hole portion 253. The convex portion 212 of the first acrylic plate 21 is rotatably inserted into the hole portion 251 of the second connecting portion 25. The convex portion 222 of the second acrylic plate 22 is rotatably inserted into the hole portion 252 of the second connecting portion 25. The convex portion 232 of the third acrylic plate 23 is inserted into the hole portion 253 of the second connecting portion 25. Since the hole portion 253 is rectangular, the convex portion 232 of the third acrylic plate 23 is not rotatable with respect to the second connecting portion 25.

[0026] As described above, the convex parts 211, 212 of the first acrylic plate 21 and the convex parts 221, 222 of the second acrylic plate 22 are rotatable with respect to the holes 241, 242 of the first connecting part 24 and the holes 251, 252 of the second connecting part 25, respectively. That is, the first acrylic plate 21 is rotatable around an axis connecting the convex parts 211 and 212, and the second acrylic plate 22 is rotatable around an axis connecting the convex parts 221 and 222. With such a mechanism, the first acrylic plate 21 and the second acrylic plate 22 rotate with respect to the first connecting part 24 and the second connecting part 25, respectively, so that the main body part 20 can be realized in a closed state and an open state. In this embodiment, each hole part of the first connecting part 24 and the second connecting part 25 is a through hole, but is not limited thereto, and may be a recess into which each convex part can be inserted.

[0027] Next, a mechanism for limiting the angle between the first acrylic plate 21 and the second acrylic plate 22 when the main body part 20 is open will be described with reference to Figures 5(a) and (b). Figures 5(a) and (b) are views of the main body part 20 as viewed from the lower side (bottom side), with Figure 5(a) showing the main body part 20 in an open state and Figure 5(b) showing the main body part 20 in a closed state.

[0028] As shown in Fig. 5(a) and (b), the second connecting portion 25 is provided with inclined surface portions (notches, grooves) 255 and 256. The inclined surface portions 255 and 256 have mutually symmetrical inclined surfaces. As shown in Fig. 5(a), when the first acrylic plate 21 and the second acrylic plate 22 are opened (when the angle between the first acrylic plate 21 and the second acrylic plate 22 is increased), the first acrylic plate 21 finally comes into contact with the inclined surface portion 255 of the second connecting portion 25, and the second acrylic plate 22 finally comes into contact with the inclined surface portion 256 of the second connecting portion 25. The inclined surface portions 255 and 256 function as limiting portions for limiting the angle (opening angle) between the first acrylic plate 21 and the second acrylic plate 22. With this structure, the angle between the first acrylic plate 21 and the second acrylic plate 22 is restricted so as not to exceed a predetermined angle θ.

[0029] According to the configuration of this embodiment, when the main body 20 is opened, the maximum angle (predetermined angle θ) between the first acrylic plate 21 and the second acrylic plate 22 can be determined according to the angle of the inclined surface portions 255 and 256 of the second connecting portion 25. That is, the angle between the inclined surface portion 255 and the inclined surface portion 256 corresponds to the predetermined angle θ. Here, the predetermined angle θ is preferably set to an angle smaller than 180 degrees so that the first acrylic plate 21 and the second acrylic plate 22 look like an open book to the user when the main body 20 is opened. This is because a general book is often opened at an angle smaller than 180 degrees (however, it is not prohibited to set the maximum angle to an angle of 180 degrees or more). Preferably, the predetermined angle θ is 75 degrees or more and 150 degrees or less. More preferably, the predetermined angle θ is 90 degrees or more and 120 degrees or less.

[0030] In this embodiment, the first connecting part 24 does not have a slope part (notch part) that functions as a limiting part like the second connecting part 25. That is, the first connecting part 24 only needs to have a mechanism for connecting the first acrylic plate 21, the second acrylic plate 22, and the third acrylic plate 23, so the size of the first connecting part 24 can be reduced. Therefore, it is possible to prevent the first connecting part 24 located at the upper part from getting in the way when viewing the pattern. Note that the first connecting part 24 may be provided with a slope part (notch part) that functions as a limiting part, so that the angle formed by the first acrylic plate 21 and the second acrylic plate 22 by the first connecting part 24 is limited.

[0031] Although the preferred embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications and changes are possible within the scope of the gist of the present invention.

[0032] In this embodiment, a case has been described in which patterns or letters, etc. are printed on all of the outer surface (first surface) 51 and inner surface (second surface) 52 of the first acrylic plate 21, the outer surface (third surface) 53 and inner surface (fourth surface) 54 of the second acrylic plate 22, and the back surface (fifth surface) 55 of the third acrylic plate 23, but this is not limited thereto. It is sufficient that patterns or letters, etc. are printed on at least one of the two outer surfaces (first surface and third surface) and at least one of the two inner surfaces (second surface and fourth surface). Preferably, patterns or letters, etc. are printed on at least three surfaces. In addition, the main body 20 of this embodiment has a third acrylic plate 23 with a back surface 55, but this is not limited thereto. It may not have a third acrylic plate 23, or it may have a third acrylic plate without a back surface 55.

[0033] In this embodiment, the first acrylic plate 21 and the second acrylic plate 22, and the third acrylic plate 23, the first connecting portion 24, and the second connecting portion 25 constituting the biaxial hinge are each manufactured from an acrylic plate of the same material and thickness, so that the members constituting the biaxial hinge can be produced at low cost, but this is not limited to this. At least a part of these members may be made of a material or thickness different from that of the other members. Furthermore, the size or shape of these members is not limited to this embodiment, and they may be of different sizes or shapes within the scope of the gist. Furthermore, in this embodiment, the first acrylic plate 21 and the second acrylic plate 22 are configured to be openable and closable by a biaxial hinge mechanism using the first connecting portion 24 and the second connecting portion 25, but this is not limited to this, and other opening and closing mechanisms may be adopted. Furthermore, in this embodiment, the patterns or characters printed on each surface are not replaceable, but may be configured to be replaceable. In this embodiment, the base 30 is composed of the first holding portion 31, the second holding portion 32, and the seat portion 33, but is not limited thereto, and other configurations on which the main body 20 can be placed may be adopted. In this embodiment, the base 30 is not provided with a mechanism for limiting the angle between the first acrylic plate 21 and the second acrylic plate 22. However, when neither the first connecting portion 24 nor the second connecting portion 25 is provided with a slope portion (notch portion) for limiting the angle, a protrusion (convex portion) may be provided on the base 30 to provide a mechanism for limiting the opening angle of the first connecting portion 24 and the second connecting portion 25.
