[0001] The present invention relates to a display case and a method for manufacturing the display case.

Background Art

[0002] In exhibition spaces such as public facilities, museums, and art galleries, display cases may be arranged. The display case needs to protect the exhibits housed inside and display the exhibits in a state where they are easily visible from the outside. For this reason, as display cases, those formed with glass plates on all four sides (so-called lantern-shaped display cases) are often used as in Patent Document 1 and Patent Document 2. In the display cases disclosed in such Patent Document 1 and Patent Document 2, a lighting device for illuminating the exhibits is provided on the upper part. The wiring for supplying power to the lighting device may interfere with the visual recognition of the exhibits from the outside. For this reason, the display cases disclosed in Patent Document 1 and Patent Document 2 are provided with tubular members at the connection portions between the glass plates, and the wiring is inserted inside the tubular members. Further, Patent Document 3 discloses a display case in which wiring is arranged along a seal member that connects the glass plates.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The display cases disclosed in Patent Document 1 and Patent Document 2 have a large tubular member visibly exposed from the outside as compared with the wiring, which deteriorates the appearance. On the other hand, in the display case disclosed in Patent Document 3, the wiring is disposed in the article storage space in an exposed state. Therefore, when performing an operation such as replacing an exhibit, the wiring is likely to come off from the seal member when the operator touches the wiring or due to aging deterioration.

[0005] The present invention has been made in view of the above-described problems, and an object thereof is to provide a display case having a good appearance and capable of preventing wiring from coming off from a defined position.

Means for Solving the Problems

[0006] As means for solving the above problems, the present invention adopts the following configuration.

[0007] A first aspect of the present invention is a display case in which an internal article storage space is visible from the outside, including a laminated transparent plate having a first transparent plate with an inner wall surface facing the article storage space and a second transparent plate superposed on the first transparent plate in a state where an outer wall surface is connected to the inner wall surface of the first transparent plate, the laminated transparent plate having a wiring accommodation groove portion capable of accommodating at least a part of wiring at a side end surface connected to another plate material via a seal member, and the wiring accommodation groove portion being formed by a fact that one end surface of the second transparent plate in a horizontal width direction is located on the other end surface side of the first transparent plate in the width direction with respect to one end surface of the first transparent plate in the width direction.

[0008] According to the first aspect of the present invention as described above, a wiring accommodation groove is provided on the side end surface of the laminated transparent plate. Therefore, the wiring can be guided without separately using a tubular member for accommodating the wiring. Thus, according to the first aspect of the present invention, the tubular member is not visible from the outside, and the appearance is improved. Further, according to the first aspect of the present invention, with the wiring accommodated in the wiring accommodation groove, the side end surface of the laminated transparent plate is connected to another plate material via a sealing member. Therefore, the wiring is accommodated between the laminated transparent plate and another plate material and does not become exposed in the article accommodation space. Thus, according to the first aspect of the present invention, it is possible to prevent the wiring from deviating from the defined position. Such a first aspect of the present invention provides a display case with a good appearance and capable of preventing the wiring from deviating from the defined position.

[0009] According to a second aspect of the present invention, in the first aspect described above, a step portion formed by bending and connecting at least a part of the one end surface of the second transparent plate and the inner wall surface of the first transparent plate is provided on the side end surface, and the wiring accommodation groove is formed by the step portion.

[0010] According to the second aspect of the present invention as described above, the wiring accommodation groove is formed by a step portion provided by bending and connecting at least a part of the one end surface of the second transparent plate and the inner wall surface of the first transparent plate. When the first transparent plate and the second transparent plate are overlapped, the inner wall surface of the first transparent plate and the one end surface of the second transparent plate are connected at a right angle or substantially at a right angle. The step portion formed by connecting the inner wall surface of the first transparent plate and the one end surface of the second transparent plate has a large depth dimension and can accommodate the entire wiring. Therefore, for example, when manufacturing the display case, it is possible to prevent the wiring from protruding from the wiring accommodation groove. Thus, the workability during the manufacture of the display case can be improved.

[0011] According to a third aspect of the present invention, in the first or second aspect described above, a configuration is adopted in which a wiring holding portion for holding the wiring in the wiring accommodation groove is provided.

[0012] According to the third aspect of the present invention as described above, the wiring holding portion fixes the position of the wiring accommodated in the wiring accommodation groove portion. Therefore, when manufacturing the display case, it is possible to prevent the wiring from protruding from the wiring accommodation groove portion.

[0013] The fourth aspect of the present invention adopts a configuration in which, in the third aspect, the wiring holding portion is formed of a part of the seal member.

[0014] According to the fourth aspect of the present invention as described above, it is not necessary to provide the wiring holding portion separately from the seal member, and the wiring holding portion can be made difficult to be visually recognized from the outside. Therefore, according to the fourth aspect of the present invention, it is possible to improve the appearance of the display case.

[0015] The fifth aspect of the present invention is such that, in any one of the first to fourth aspects, the first side end surface, which is the side end surface, has a first inclined surface that is inclined so as to face the second side end surface, which is the side end surface of the laminated transparent plate located on the opposite side of the first side end surface, as it goes from the outer wall surface side of the laminated transparent plate toward the inner wall surface side of the laminated transparent plate. The first connection side end surface, which is the side end surface of the plate material connected to the laminated transparent plate of the plate material, has a second inclined surface that is inclined so as to face the second connection side end surface, which is the side end surface of the plate material located on the opposite side of the connection side end surface, as it goes from the outer wall surface side of the plate material toward the inner wall surface side of the plate material. A configuration is adopted in which the laminated transparent plate and the plate material are connected via the seal member in a state where the first inclined surface of the laminated transparent plate and the second inclined surface of the plate material face each other.

[0016] According to the fifth aspect of the present invention as described above, the laminated transparent plate and other plate materials can be bent and connected. Therefore, for example, when formed in a polyhedral shape in which adjacent transparent plates are bent and connected, it is possible to form the entire one transparent plate with the laminated transparent plate. In addition, it is possible to widely secure the contact area between the laminated transparent plate and the seal member and the contact area between the other plate material and the seal member. Therefore, the connection strength between the laminated transparent plate and the other plate material can be improved.

[0017] In the sixth aspect of the present invention, in any one of the first to fifth aspects, an electrical device located above the article storage space is provided, and the wiring is a power supply cable that supplies power to the electrical device.

[0018] According to such a sixth aspect of the present invention, it becomes possible to supply power to an electrical device via the wiring. Therefore, according to the sixth aspect of the present invention, for example, electrical devices such as lighting devices and air conditioning devices can be provided. In addition, such electrical devices can be supplied with power using wiring that is difficult to visually recognize from the outside and is difficult to come off. Therefore, according to the sixth aspect of the present invention, a display case that is equipped with an electrical device and in which the power supply cable is difficult to visually recognize from the outside and is difficult to come off is obtained.

[0019] The seventh aspect of the present invention is a method for manufacturing a display case in which an internal article storage space is visible from the outside, the display case includes a laminated transparent plate, the laminated transparent plate has a first transparent plate whose inner wall surface faces the article storage space, and a second transparent plate that is superposed on the first transparent plate in a state where an outer wall surface is connected to the inner wall surface of the first transparent plate, the laminated transparent plate has a wiring accommodation groove portion capable of accommodating at least a part of the wiring at a side end surface connected to another plate material via a seal member, the wiring accommodation groove portion is formed by the fact that one end surface of the second transparent plate in the horizontal width direction is located on the other end surface side of the first transparent plate in the width direction than one end surface of the first transparent plate in the width direction, a wiring accommodation step of accommodating the wiring in the wiring accommodation groove portion, a wiring holding step of holding the wiring accommodated in the wiring accommodation groove portion by embedding the wiring accommodation groove portion with a wiring holding portion, and a connection step of connecting the side end surface of the laminated transparent plate to the plate material via the seal member after the wiring holding step.

[0020] According to the seventh aspect of the present invention, wiring is accommodated in a wiring accommodation groove provided on a side end face of a laminated transparent plate. Therefore, the wiring can be guided without separately using a tubular member for accommodating the wiring. Thus, according to the seventh aspect of the present invention, the tubular member is not visually recognized from the outside, and the appearance is improved. Further, according to the seventh aspect of the present invention, with the wiring accommodated in the wiring accommodation groove, the side end face of the laminated transparent plate is connected to another plate material via a sealing member. For this reason, the wiring is accommodated between the laminated transparent plate and another plate material and does not become exposed in the article accommodation space. Thus, according to the seventh aspect of the present invention, it is possible to prevent the wiring from coming off from a defined position. Such a seventh aspect of the present invention enables the production of a display case that has a good appearance and can further prevent the wiring from coming off from a defined position.

Modes for Carrying Out the Invention

[0023] Hereinafter, with reference to the drawings, an embodiment of a display case and a method for manufacturing the display case according to the present invention will be described.

[0024] (First Embodiment) FIG. 1 is a schematic perspective view of the display case 1 of the present embodiment. The display case 1 of the present embodiment is installed in a display space such as a public facility, a museum, or an art museum, and allows the internal article storage space K to be visible from the outside. An exhibit X (article) is stored in the article storage space K. That is, the display case 1 of the present embodiment protects the exhibit X stored in the article storage space K so that it can be visually recognized from the outside.

[0025] The display case 1 of the present embodiment is a lantern-shaped case that surrounds the article storage space K using four transparent plates 3 connected in a rectangular shape in plan view. As shown in FIG. 1, such a display case 1 of the present embodiment includes a base 2, a transparent plate 3, a seal member 4, a ceiling portion 5, a lighting device 6 (electrical equipment), and an AC adapter unit 7. For the sake of convenience of explanation, one direction along the horizontal plane is defined as the X direction, and a direction along the horizontal plane and orthogonal to the X direction is defined as the Y direction.

[0026] The base 2 forms the bottom of the display case 1 of the present embodiment and is placed, for example, on the floor surface F from above. This base 2 directly or indirectly supports, for example, the transparent plate 3, the seal member 4 (see FIG. 2), the ceiling portion 5, and the lighting device 6. The base 2 is formed so as to have a rectangular shape in plan view and, for example, is hollow inside. Inside the base 2, for example, a power conversion unit 7a of the AC adapter unit 7 described later is housed.

[0027] In addition, the base 2 may be provided with a plurality of adjusters. By providing the base 2 with adjusters, it becomes possible to adjust the height and inclination of the display case 1. Further, the base 2 may be provided with a plurality of casters. By providing the base 2 with casters, the movement of the display case 1 can be facilitated.

[0028] The transparent plate 3 is a plate-shaped member that can transmit visible light and separates the outer space K1 from the article storage space K. FIG. 2 is a schematic cross-sectional view of the display case 1 including the transparent plate 3 in the horizontal plane. As shown in this figure, the display case 1 of the present embodiment includes four transparent plates 3. These transparent plates 3 are arranged to be rectangular in plan view, and the side end faces are connected to each other via a seal member 4. As shown in FIG. 2, the display case 1 of the present embodiment includes, as the transparent plate 3, one wiring holding transparent plate 10 (laminated transparent plate) and three normal transparent plates 20. Note that a plurality of wiring holding transparent plates 10 (laminated transparent plates) may be provided.

[0029] The wiring holding transparent plate 10 is a transparent plate 3 that houses a power supply cable 7b, which will be described later, of the AC adapter unit 7. The wiring holding transparent plate 10 is arranged such that the outer wall surface 10a faces the -Y direction and the inner wall surface 10b faces the +Y direction. The outer wall surface 10a is a wall surface exposed to the outer space K1. The inner wall surface 10b is a wall surface exposed to the article storage space K. Such a wiring holding transparent plate 10 includes, as shown in FIG. 2, an outer transparent plate 11 (first transparent plate), an inner transparent plate 12 (second transparent plate), and an adhesive layer 13.

[0030] The outer transparent plate 11 is a transparent plate-shaped member located outside (on the outer space K1 side) of the inner transparent plate 12. The outer transparent plate 11 can be formed of, for example, glass or acrylic. The outer transparent plate 11 is arranged such that the outer wall surface 11a faces the -Y direction and the inner wall surface 11b faces the +Y direction. The outer wall surface 11a of such an outer transparent plate 11 forms the outer wall surface 10a of the wiring holding transparent plate 10. The inner wall surface 11b of the outer transparent plate 11 is connected to the outer wall surface 12a of the inner transparent plate 12 via the adhesive layer 13.

[0031] The inner transparent plate 12 is a transparent plate-like member located on the inner side (on the article storage space K side) of the outer transparent plate 11. The inner transparent plate 12 can be formed of, for example, glass or acrylic. For the inner transparent plate 12, the outer wall surface 12a is directed in the -Y direction, and the inner wall surface 12b is directed in the +Y direction. The inner wall surface 12b of such an inner transparent plate 12 forms the inner wall surface 10b of the wiring holding transparent plate. Further, the outer wall surface 12a of the inner transparent plate 12 is connected to the inner wall surface 11b of the outer transparent plate 11 via an adhesive layer 13.

[0032] The adhesive layer 13 is a layer that adheres the outer transparent plate 11 and the inner transparent plate 12 and is formed of a transparent resin. The wiring holding transparent plate 10 is formed by overlapping the outer transparent plate 11 and the inner transparent plate 12 via such an adhesive layer 13. That is, the wiring holding transparent plate 10 is a laminated transparent plate having the outer transparent plate 11 and the inner transparent plate 12 that is overlapped on the outer transparent plate 11 with the outer wall surface 12a connected to the inner wall surface 11b of the outer transparent plate 11.

[0033] Note that it is also possible to overlap the outer transparent plate 11 and the inner transparent plate 12 by providing a sash that holds the outer edge of the outer transparent plate 11 and the outer edge of the inner transparent plate 12. In such a case, it is not always necessary to provide the adhesive layer 13, and the inner wall surface 11b of the outer transparent plate 11 and the outer wall surface 12a of the inner transparent plate 12 are directly abutted.

[0034] Such a wiring holding transparent plate 10 has two side end faces 14 that are connected to a normal transparent plate 20, which is another plate material, via a seal member 4. One side end face 14 is located on the most -X side of the wiring holding transparent plate 10. Further, the other side end face 14 is located on the most +X side of the wiring holding transparent plate 10.

[0035] Among these side end faces 14, a wiring accommodation groove portion 15 is provided in the side end face 14 located on the -X side (hereinafter referred to as the first side end face 14a). That is, the wiring holding transparent plate 10 has a wiring accommodation groove portion 15 in the first side end face 14a that is connected to the normal transparent plate 20 via the seal member 4.

[0036] The wiring accommodation groove portion 15 is a groove portion for accommodating the power supply cable 7b of the AC adapter unit 7, and is linearly formed from the upper end to the lower end of the wiring holding transparent plate 10. As shown in FIG. 2, this wiring accommodation groove portion 15 is formed by a stepped portion 16. Further, the stepped portion 16 is formed by the partial bending and connection of an end face 12c (one end face) of the inner transparent plate 12 in the horizontal width direction (X direction) and the inner wall surface 11b of the outer transparent plate 11.

[0037] The -X side end face 12c of the inner transparent plate 12 has a flat surface 12c1 parallel to the Y direction and an inclined surface 12c2 inclined with respect to the Y direction, as shown in FIG. 2. The flat surface 12c1 is located on the -Y side of the inclined surface 12c2. The inclined surface 12c2 is inclined so as to face an end face 12d (the other end face) located on the opposite side (+X side) of the end face 12c as it goes from the outer wall surface 12a to the inner wall surface 12b. The above-mentioned stepped portion 16 is formed by the flat surface 12c1, which is a part of the end face 12c, being connected to the inner wall surface 11b of the outer transparent plate 11 at a right angle.

[0038] Also, the -X side end face 11c of the outer transparent plate 11 is an inclined surface that inclines so as to face an end face 11d (the other end face) located on the opposite side (+X side) of the end face 11c as it goes from the outer wall surface 11a to the inner wall surface 11b. As shown in FIG. 2, the end face 11c of the outer transparent plate 11 is located on the same plane as the inclined surface 12c2 of the inner transparent plate 12.

[0039] The first side end face 14a of the wiring holding transparent plate 10 is a surface including the end face 11c of the outer transparent plate 11 and the inclined surface 12c2 of the inner transparent plate 12, and is inclined so as to face the side end face (the second side end face 14b) of the wiring holding transparent plate 10 located on the opposite side of the first side end face 14a as it goes from the outer wall surface 10a to the inner wall surface 10b. The wiring holding transparent plate 10 has a stepped portion 16 provided so as to be recessed in the inclined first side end face 14a, and has a wiring accommodation groove portion 15 formed by this stepped portion 16.

[0040] In this way, the wiring accommodation groove portion 15 is formed by the end face 12c of the inner transparent plate 12 being located on the +X side with respect to the end face 11c of the outer transparent plate 11. Here, the end face 12c of the inner transparent plate 12 being located on the +X side with respect to the end face 11c of the outer transparent plate 11 means that the end face 12c of the inner transparent plate 12 is located on the +X side with respect to the most +X-side position of the end face 11c of the outer transparent plate 11. Furthermore, in the present embodiment, since the end face 12c of the inner transparent plate 12 is separated from the end face 11c of the outer transparent plate 11 in the X direction, the step portion 16 is formed, and the wiring accommodation groove portion 15 having a large depth dimension is formed.

[0041] The second side end face 14b of the wiring holding transparent plate 10 is a plane including the +X-side end face 11d of the outer transparent plate 11 and the +X-side end face 12d of the inner transparent plate 12, and is inclined so as to face the side end face (first side end face 14a) of the wiring holding transparent plate 10 located on the opposite side to the second side end face 14b as it goes from the outer wall surface 10a toward the inner wall surface 10b. Note that the wiring accommodation groove portion 15 may be provided at the second side end portion 14b.

[0042] The normal transparent plate 20 is formed in a transparent plate shape having an outer wall surface 20a and an inner wall surface 20b. The outer wall surface 20a is a wall surface exposed to the outer space K1. The inner wall surface 20b is a wall surface exposed to the article accommodation space K. Such a normal transparent plate 20 includes an outer transparent plate 21, an inner transparent plate 22, and an adhesive layer 23, as shown in FIG. 2.

[0043] The outer transparent plate 21 is a transparent plate-shaped member located outside (on the outer space K1 side) the inner transparent plate 22. The outer transparent plate 21 can be formed of, for example, glass or acrylic. The outer wall surface 21a of such an outer transparent plate 21 forms the outer wall surface 20a of the normal transparent plate 20. The inner wall surface 21b of the outer transparent plate 21 is connected to the outer wall surface 22a of the inner transparent plate 22 via the adhesive layer 23.

[0044] The inner transparent plate 22 is a transparent plate-shaped member located on the inner side (on the article storage space K side) of the outer transparent plate 21. The inner transparent plate 22 can be formed of, for example, glass or acrylic. The inner wall surface 22b of such an inner transparent plate 22 forms the inner wall surface 20b of the wiring holding transparent plate. Further, the outer wall surface 22a of the inner transparent plate 22 is connected to the inner wall surface 21b of the outer transparent plate 21 via an adhesive layer 23.

[0045] The adhesive layer 23 is a layer that adheres the outer transparent plate 21 and the inner transparent plate 22, and is formed of a transparent resin. The normal transparent plate 20 is formed by overlapping the outer transparent plate 21 and the inner transparent plate 22 via such an adhesive layer 23.

[0046] Note that it is also possible to overlap the outer transparent plate 21 and the inner transparent plate 22 by providing a sash that holds the outer edge of the outer transparent plate 21 and the outer edge of the inner transparent plate 22. In such a case, it is not always necessary to provide the adhesive layer 23, and the inner wall surface 21b of the outer transparent plate 21 and the outer wall surface 22a of the inner transparent plate 22 are directly in contact.

[0047] The side end surface 24 of the normal transparent plate 20 is a surface including the end surface 21c of the outer transparent plate 21 and the end surface 22c of the inner transparent plate 22, and is inclined so as to face the side end surface 24 of the normal transparent plate 20 located on the opposite side as it goes from the outer wall surface 20a toward the inner wall surface 20b.

[0048] Note that in the present embodiment, the normal transparent plate 20 is a multi-layer transparent plate including the outer transparent plate 21 and the inner transparent plate 22. However, the normal transparent plate 20 may be a single-layer transparent plate. In such a case, the normal transparent plate 20 also does not have an adhesive layer 23.

[0049] Of the three normal transparent plates 20, one is arranged such that the outer wall surface 20a faces the -X direction and the inner wall surface 20b faces the +X direction. For convenience of explanation, this normal transparent plate 20 is referred to as the first normal transparent plate 30. The first normal transparent plate 30 is arranged in a state where the side end surface 24 on the -Y side faces the first side end surface 14a of the wiring holding transparent plate 10. Also, the side end surface 24 on the -Y side of the first normal transparent plate 30 is connected to the first side end surface 14a of the wiring holding transparent plate 10 via the seal member 4.

[0050] Also, one of the two normal transparent plates 20 excluding the first normal transparent plate 30 among the three normal transparent plates 20 is arranged such that the outer wall surface 20a faces the +Y direction and the inner wall surface faces the -Y direction. For convenience of explanation, this normal transparent plate 20 is referred to as the second normal transparent plate 31. The second normal transparent plate 31 is arranged in a state where the side end surface 24 on the -X side faces the side end surface 24 on the +Y side of the first normal transparent plate 30. Also, the side end surface 24 on the -X side of the second normal transparent plate 31 is connected to the side end surface 24 on the +Y side of the first normal transparent plate 30 via the seal member 4.

[0051] Also, the remaining one of the three normal transparent plates 20 excluding the first normal transparent plate 30 and the second normal transparent plate 31 is arranged such that the outer wall surface 20a faces the +X direction and the inner wall surface faces the -X direction. For convenience of explanation, this normal transparent plate 20 is referred to as the third normal transparent plate 32. The third normal transparent plate 32 is arranged in a state where the side end surface 24 on the +Y side faces the side end surface 24 on the +X side of the second normal transparent plate 31. Also, the side end surface 24 on the +Y side of the third normal transparent plate 32 is connected to the side end surface 24 on the +X side of the second normal transparent plate 31 via the seal member 4. Further, the third normal transparent plate 32 is arranged in a state where the side end surface 24 on the -Y side faces the second side end surface 14b of the wiring holding transparent plate 10. Also, the side end surface 24 on the -Y side of the third normal transparent plate 32 is connected to the second side end surface 14b of the wiring holding transparent plate 10 via the seal member 4.

[0052] The seal member 4 is disposed between the side end faces of the transparent plates 3, and fills the gap between the side end faces of the transparent plates 3. In the present embodiment, four seal members 4 are provided. Among these four seal members 4, the seal member 4 (hereinafter referred to as the wiring holding seal member 41) located between the wiring holding transparent plate 10 and the first normal transparent plate 30 has a wiring holding portion 41a that embeds the wiring accommodation groove portion 15 as shown in FIG. 2.

[0053] The wiring holding portion 41a is a portion that protrudes from the main body portion 41b of the seal member 4 toward the wiring accommodation groove portion 15, and is fixed to the inner wall surface of the wiring accommodation groove portion 15. Such a wiring holding portion 41a molds the power supply cable 7b accommodated in the wiring accommodation groove portion 15. Further, the wiring holding portion 41a is formed of the same material as the main body portion 41b. However, it is also possible to form the wiring holding portion 41a of a material different from that of the main body portion 41b.

[0054] All the seal members 4 may be fixed to the side end faces of the contacting transparent plates 3. In such a case, by lifting all the transparent plates 3 with respect to the base 2, the exhibit X can be taken in and out of the article accommodation space K. Further, any one of the four transparent plates 3 may be made openable and closable so that the exhibit X can be taken in and out of the article accommodation space K. In such a case, one side of any one of the seal members 4 is not fixed to the side end face of the transparent plate 3 but only abuts thereon so that the openable and closable transparent plate 3 can be moved.

[0055] Returning to FIG. 1, the ceiling portion 5 forms the upper part of the display case 1 of the present embodiment and is supported from below by the transparent plate 3. The ceiling portion 5 is formed in a rectangular shape in plan view similar to the base 2 and covers the article accommodation space K from above. Further, the ceiling portion 5 supports the lighting device 6 from above.

[0056] The lighting device 6 is fixed to the lower surface of the ceiling portion 5 and is located above the article storage space K. The lighting device 6 is a power device that is supplied with DC power from the AC adapter unit 7 and converts the power into illumination light. The lighting device 6 emits illumination light downward to illuminate the exhibit X housed in the article storage space K from above.

[0057] The AC adapter unit 7 is a unit that supplies power to the lighting device 6, and includes a power conversion unit 7a and a power supply cable 7b (wiring). The power conversion unit 7a is a converter that converts AC power supplied from an AC power source (not shown) into DC power. For example, the power conversion unit 7a is housed inside the base 2. However, the position of the power conversion unit 7a can be changed.

[0058] The power supply cable 7b is a wiring that connects the power conversion unit 7a and the lighting device 6. In the present embodiment, DC power supplied from the power conversion unit 7a to the lighting device 6 flows through the power supply cable 7b. As shown in FIG. 2, an intermediate portion of the power supply cable 7b is housed in the wiring housing groove portion 15 of the wiring holding transparent plate 10 and is held by a part of the seal member 4. Most of such a power supply cable 7b, excluding the upper end portion and the lower end portion, is housed in the wiring housing groove portion 15. The portion of such a power supply cable 7b housed in the wiring housing groove portion 15 is arranged without being exposed to the article storage space K.

[0059] FIG. 3 is a schematic diagram showing a part of the manufacturing method of the display case 1 of this embodiment. Here, the step of connecting the wiring holding transparent plate 10 and the first normal transparent plate 30 will be described. First, as shown in FIG. 3(a), the wiring holding transparent plate 10 is prepared. Subsequently, as shown in FIG. 3(b), the power supply cable 7b is housed inside the wiring housing groove portion 15. The step shown in FIG. 3(b) is a wiring housing step of housing the power supply cable 7b in the wiring housing groove portion 15.

[0060] Subsequently, as shown in FIG. 3(c), a wiring holding portion 41a (a part of the wiring holding seal member 41) is formed in the wiring accommodation groove portion 15. For example, the wiring accommodation groove portion 15 in which the power supply cable 7b is accommodated is embedded with a forming material in a softened state. Thereafter, the wiring holding portion 41a is formed by curing the forming material. By forming such a wiring holding portion 41a, the power supply cable 7b is held in the wiring accommodation groove portion 15. The process shown in FIG. 3(c) like this is a wiring holding process for holding the power supply cable 7b accommodated in the wiring accommodation groove portion 15 by embedding the wiring accommodation groove portion 15 with the wiring holding portion 41a.

[0061] Subsequently, as shown in FIG. 3(d), with the first side end face 14a of the wiring holding transparent plate 10 and the side end face 24 of the first normal transparent plate 30 facing each other, the wiring holding transparent plate 10 and the first normal transparent plate 30 are connected by a seal member 4. As a result, the main body portion 41b and the wiring holding portion 41a are integrated, and the wiring holding seal member 41 is formed. The process shown in FIG. 3(d) like this is a connecting process for connecting the first side end face 14a of the wiring holding transparent plate 10 to the first normal transparent plate 30 via the seal member 4 after the wiring holding process.

[0062] The display case 1 of the present embodiment as described above is a display case 1 in which the internal article accommodation space can be visually recognized from the outside. Further, the display case 1 includes a wiring holding transparent plate 10. The wiring holding transparent plate 10 has an outer transparent plate 11 and an inner transparent plate 12. For the outer transparent plate 11, the inner wall surface 11b faces the article accommodation space K. The inner transparent plate 12 is superposed on the outer transparent plate 11 in a state where an outer wall surface 12a is connected to the inner wall surface 11b of the outer transparent plate 11. Further, the wiring holding transparent plate 10 has a wiring accommodation groove portion 15. The wiring accommodation groove portion 15 is provided at a first side end face 14a that is connected to the normal transparent plate 20 via a seal member 4. Further, the wiring accommodation groove portion 15 can accommodate at least a part of the power supply cable 7b. Furthermore, the wiring accommodation groove portion 15 is formed by the end face 12c of the inner transparent plate 12 in the horizontal width direction (X direction) being located on the end face 11d side of the outer transparent plate 11 rather than the end face 11c of the outer transparent plate 11 in the same width direction (X direction).

[0063] According to the display case 1 of this embodiment, the wiring accommodation groove portion 15 is provided on the first side end surface 14a of the wiring holding transparent plate 10. Therefore, the power supply cable 7b can be guided without separately using a tubular member for accommodating the power supply cable 7b. Thus, according to the display case 1 of this embodiment, the tubular member is not visually recognized from the outside, and the appearance is improved. Further, according to the display case 1 of this embodiment, with the power supply cable 7b accommodated in the wiring accommodation groove portion 15, the side end surface 14 of the wiring holding transparent plate 10 is connected to the normal transparent plate 20 via the seal member 4. For this reason, the power supply cable 7b is accommodated between the wiring holding transparent plate 10 and the normal transparent plate 20 and is not exposed in the article accommodation space K. Thus, according to the display case 1 of this embodiment, it is possible to prevent the power supply cable 7b from coming off from the determined position. The display case 1 of this embodiment is like this, has a good appearance, and can further prevent the power supply cable 7b from coming off from the determined position.

[0064] Further, in the display case 1 of this embodiment, the step portion 16 is provided on the first side end surface 14a. The step portion 16 is formed by the end surface 12c of the inner transparent plate 12 and at least a part of the inner wall surface 11b of the outer transparent plate 11 being bent and connected. Also, the wiring accommodation groove portion 15 is formed by the step portion 16.

[0065] According to the display case 1 of this embodiment, the wiring accommodation groove 15 is formed by a step portion 16 provided by bending and connecting at least a part of the end face 12c of the inner transparent plate 12 and the inner wall surface 11b of the outer transparent plate 11. When the outer transparent plate 11 and the inner transparent plate 12 are overlapped, the inner wall surface 11b of the outer transparent plate 11 and the end face 12c of the inner transparent plate 12 are connected at a right angle or substantially at a right angle. The step portion 16 formed by connecting the inner wall surface 11b of the outer transparent plate 11 and the end face 12c of the inner transparent plate 12 has a large depth dimension and can accommodate the entire power supply cable 7b. Therefore, the display case 1 of this embodiment can, for example, prevent the wiring from protruding from the wiring accommodation groove 15 during the manufacture of the display case 1. Thus, the display case 1 of this embodiment can improve the workability during the manufacture of the display case 1.

[0066] Further, the display case 1 of this embodiment has a wiring holding portion 41a that holds the power supply cable 7b in the wiring accommodation groove 15. According to the display case 1 of this embodiment, the position of the power supply cable 7b accommodated in the wiring accommodation groove 15 is fixed by the wiring holding portion 41a. Therefore, the display case 1 of this embodiment can prevent the power supply cable 7b from protruding from the wiring accommodation groove 15 during the manufacture of the display case 1.

[0067] Further, in the display case 1 of this embodiment, the wiring holding portion 41a is a part of the seal member 4. According to the display case 1 of this embodiment, it is not necessary to provide the wiring holding portion 41a separately from the seal member 4, and the wiring holding portion 41a can be made difficult to be visually recognized from the outside. Therefore, according to the display case 1 of this embodiment, the appearance of the display case 1 can be improved.

[0068] In the display case 1 of the present embodiment, the side end face 14 (first side end face) has an inclined surface (first inclined surface) that is inclined so as to face the side end face 14 (second side end face) of the wiring holding transparent plate 10 located on the opposite side as it goes from the outer wall surface 10a side of the wiring holding transparent plate 10 toward the inner wall surface 10b side. Further, the side end face 24 (first connection side end face) of the normal transparent plate 20 connected to the wiring holding transparent plate 10 has an inclined surface that is inclined so as to face the side end face 24 (second connection side end face) of the normal transparent plate 20 located on the opposite side as it goes from the outer wall surface 20a side of the normal transparent plate 20 toward the inner wall surface 20b side. In the display case 1 of the present embodiment, the wiring holding transparent plate 10 and the normal transparent plate 20 are connected via the sealing member 4 in a state where the inclined surface (first inclined surface) of the wiring holding transparent plate 10 and the inclined surface (second inclined surface) of the normal transparent plate 20 face each other.

[0069] According to the display case 1 of such a present embodiment, the wiring holding transparent plate 10 and the normal transparent plate 20 can be bent and connected. For this reason, for example, when the display case 1 is formed in a polyhedral shape in which adjacent transparent plates 3 are bent and connected as in the present embodiment, it becomes possible to form the entire one transparent plate 3 with the wiring holding transparent plate 10. Further, a wide contact area between the wiring holding transparent plate 10 and the sealing member 4 can be ensured. Also, a wide contact area between the normal transparent plate 20 and the sealing member 4 can be ensured. Therefore, the connection strength between the wiring holding transparent plate 10 and the normal transparent plate 20 can be improved.

[0070] Further, the display case 1 of the present embodiment includes a lighting device 6 located above the article storage space K. Also, the power supply cable 7b supplies power to the lighting device 6. According to the display case 1 of such a present embodiment, it becomes possible to supply power to the lighting device 6 via the power supply cable 7b. According to the display case 1 of such a present embodiment, the lighting device 6 can be powered using the power supply cable 7b that is difficult to be visually recognized from the outside and difficult to come off. Therefore, although the display case 1 of the present embodiment includes the lighting device 6, the power supply cable 7b is difficult to be visually recognized from the outside and difficult to come off.

[0071] Further, the manufacturing method of the display case 1 of the present embodiment is a manufacturing method of the display case 1 in which the internal article accommodation space K can be visually recognized from the outside. The manufacturing method of the display case 1 of the present embodiment includes a wiring accommodation step, a wiring holding step, and a connection step. The wiring accommodation step is a step of accommodating the power supply cable 7b in the wiring accommodation groove portion 15. The wiring holding step is a step of holding the power supply cable 7b accommodated in the wiring accommodation groove portion 15 by embedding the wiring accommodation groove portion 15 with the wiring holding portion 41a. The connection step is a step of connecting the side end surface 14 of the wiring holding transparent plate 10 to the normal transparent plate 20 via the seal member 4 after the wiring holding step.

[0072] According to the manufacturing method of the display case 1 of the present embodiment as described above, the power supply cable 7b is accommodated in the wiring accommodation groove portion 15 provided with respect to the first side end surface 14a of the wiring holding transparent plate 10. Therefore, the wiring can be guided without separately using a tubular member for accommodating the power supply cable 7b. Therefore, in the display case 1 manufactured by the manufacturing method of the display case 1 of the present embodiment, the tubular member is not visually recognized from the outside, and the appearance is improved.

[0073] Further, according to the manufacturing method of the display case 1 of the present embodiment, with the power supply cable 7b accommodated in the wiring accommodation groove portion 15, the side end surface 14 of the wiring holding transparent plate 10 is connected to the normal transparent plate 20 via the seal member 4. Therefore, the power supply cable 7b is accommodated between the wiring holding transparent plate 10 and the normal transparent plate 20 and is not exposed in the article accommodation space. Therefore, according to the manufacturing method of the display case 1 of the present embodiment, it is possible to prevent the power supply cable 7b from coming off from the determined position. According to the manufacturing method of the display case 1 of the present embodiment as described above, it is possible to manufacture a display case 1 with a good appearance and further prevent the power supply cable 7b from coming off from the determined position.

[0074] (Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIG. 4. In the description of the present embodiment, the description of the same parts as those in the first embodiment above will be omitted or simplified.

[0075] FIG. 4 is a schematic cross-sectional view of the display case 1A including the transparent plate 3 by a horizontal plane. The display case 1A of the present embodiment adopts a configuration in which the first side end face 14a of the wiring holding transparent plate 10 is not an inclined surface. The end face 11c of the outer transparent plate 11 of the wiring holding transparent plate 10 is formed as a flat surface parallel to the direction (Y direction) from the outer wall surface 11a to the inner wall surface 11b of the outer transparent plate 11. Further, the end face 12c of the inner transparent plate 12 is also formed as a flat surface parallel to the direction (Y direction) from the outer wall surface 12a to the inner wall surface 12b of the inner transparent plate 12. The first side end face 14a includes the end face 11c of the outer transparent plate 11 and the end face 12c of the inner transparent plate 12, and is formed parallel to the Y direction.

[0076] The end face 12c of the inner transparent plate 12 is bent and connected to the inner wall surface 11b of the outer transparent plate 11. Thereby, a step portion 16 formed by the end face 12c of the inner transparent plate 12 and the inner wall surface 11b of the outer transparent plate 11 is provided. In the display case 1A of the present embodiment, a wiring accommodation groove portion 15 is formed by such a step portion 16.

[0077] As in the display case 1A of the present embodiment, the first side end face 14a does not need to be a surface inclined with respect to the Y direction. Even in the display case 1A of the present embodiment, the power supply cable 7b can be guided without separately using a tubular member for accommodating the power supply cable 7b, similar to the first embodiment.

[0078] Therefore, according to the display case 1A of the present embodiment, the tubular member is not visually recognized from the outside, and the appearance is improved. Further, according to the display case 1A of the present embodiment, in a state where the power supply cable 7b is accommodated in the wiring accommodation groove portion 15, the side end face 14 of the wiring holding transparent plate 10 is connected to the normal transparent plate 20 via the seal member 4. For this reason, the power supply cable 7b is accommodated between the wiring holding transparent plate 10 and the normal transparent plate 20 and is not exposed in the article accommodation space K. Therefore, according to the display case 1A of the present embodiment, it is possible to prevent the power supply cable 7b from coming off from the determined position.

[0079] Also, in the display case 1A of the present embodiment, the first normal transparent plate 30 is not a multilayer transparent plate including the outer transparent plate 21 and the inner transparent plate 22, but a single-layer transparent plate. As shown in FIG. 4, the first side end face 14a of the wiring holding transparent plate 10 is connected to the inner wall face 20b of such a first normal transparent plate 30 via the sealing member 4. In this way, the first side end face 14a of the wiring holding transparent plate 10 may be connected to a part different from the side end face 24 of the first normal transparent plate 30.

[0080] In the present embodiment, since the first side end face 14a of the wiring holding transparent plate 10 is connected to the inner wall face 20b of the first normal transparent plate 30 via the sealing member 4, the side end face 24 of the first normal transparent plate 30 is exposed to the outer space K1. However, since the first normal transparent plate 30 is formed of a single-layer transparent plate as described above, in the display case 1A of the present embodiment, the connection line between the outer transparent plate 21 and the inner transparent plate 22 does not expose on the side end face 24.

[0081] (Third Embodiment) Next, a third embodiment of the present invention will be described with reference to FIG. 5. In the description of the present embodiment, the description of the parts similar to those in the first embodiment will be omitted or simplified.

[0082] FIG. 5 is a schematic cross-sectional view of the display case 1B including the transparent plate 3 in a horizontal plane. In the display case 1B of the present embodiment, the end face 11c of the outer transparent plate 11 of the wiring holding transparent plate 10 is inclined so as to face the other end face 11d as it goes from the outer wall face 11a to the inner wall face 11b of the outer transparent plate 11. Also, the end face 12c of the inner transparent plate 12 is inclined so as to face the other end face 12d as it goes from the outer wall face 12a to the inner wall face 12b of the inner transparent plate 12.

[0083] The end face 11c of the outer transparent plate 11 has a larger inclination angle with respect to the Y direction than the end face 12c of the inner transparent plate 12. That is, the end face 12c of the inner transparent plate 12 has a smaller inclination angle with respect to the Y direction than the end face 11c of the outer transparent plate 11. In the present embodiment, by connecting the end face 11c of the outer transparent plate 11 and the end face 12c of the inner transparent plate 12 in this manner, the first side end face 14a of the wiring holding transparent plate 10 is formed.

[0084] As shown in FIG. 5, by connecting the end face 11c of the outer transparent plate 11 and the end face 12c of the inner transparent plate 12, a wiring accommodation groove portion 15 is formed. Here, the connection angle between the end face 11c of the outer transparent plate 11 and the end face 12c of the inner transparent plate 12 is an obtuse angle. Therefore, the wiring accommodation groove portion 15 in the display case 1B of the present embodiment is formed shallower than the wiring accommodation groove portion 15 of the first embodiment. A part of the power supply cable 7b is accommodated in the wiring accommodation groove portion 15 in cross section.

[0085] Like the display case 1B of the present embodiment as described above, it is not necessary for the power supply cable 7b to be entirely accommodated in the wiring accommodation groove portion 15 in cross section. Even in the display case 1B of the present embodiment like this, similar to the first embodiment, the power supply cable 7b can be guided without separately using a tubular member for accommodating the power supply cable 7b.

[0086] Therefore, according to the display case 1B of the present embodiment, the tubular member is not visually recognized from the outside, and the appearance is improved. Further, according to the display case 1B of the present embodiment, with the power supply cable 7b accommodated in the wiring accommodation groove portion 15, the side end face 14 of the wiring holding transparent plate 10 is connected to the normal transparent plate 20 via the seal member 4. For this reason, the power supply cable 7b is accommodated between the wiring holding transparent plate 10 and the normal transparent plate 20 and is not exposed in the article accommodation space K. Therefore, according to the display case 1B of the present embodiment, it is possible to prevent the power supply cable 7b from deviating from the determined position.
