Specifically, the second panel 2 is configured such that a second glass plate 23 having permeability is supported by a second upper frame 21 and a second lower frame 22. When the second panel 2 is in a closed state, a seal member P is inserted between the second glass plate 23, the lower base plate 35, and the upper base plate 37.

[0039] A groove - shaped second upper groove 21a opening forward is formed in the second upper frame 21. Also, a groove - shaped second lower groove 22a opening forward is formed in the second lower frame 22. The second upper groove 21a and the second lower groove 22a function as the first sub - rail according to the present invention. In the present embodiment, the first sub - rail and the first main rail described later are collectively referred to as the "first rail" on which the first rollers (the first upper roller 14 and the first lower roller 15) described later roll.

[0040] At the rear of the second upper frame 21, an upper support piece 21b extending downward is formed, and a second upper closing plate 28, which is a steel plate, is fixed to the rear surface of the upper support piece 21b. The second upper closing holder 44 is configured to adsorb the second upper closing plate 28 with a permanent magnet when the second panel 2 is in a non-energized closed state, and not to adsorb the second upper closing plate 28 when energized.

[0041] Also, at the rear of the second lower frame 22, a lower support piece 22b extending upward is formed, and a second lower closing plate 29, which is a steel plate, is fixed to the rear surface of the lower support piece 22b.

[0042] On the rear surface of the second upper groove 21a in the second upper frame 21, three second upper rollers 24 extending rearward are provided (see FIG. 1). The second upper rollers 24 are inserted into the second upper rail member 26 so as to be rollable on the second upper rail 26a. That is, the second upper groove 21a of the second upper frame 21 and the second upper rail 26a of the second upper rail member 26 are arranged to overlap in the front-rear direction at the same height position.

[0043] Also, on the rear surface of the second lower groove 22a in the second lower frame 22, three second lower rollers 25 extending rearward are provided (see FIG. 1). The second lower rollers 25 are inserted into the second lower rail member 27 so as to be rollable on the second lower rail 27a. That is, the second lower groove 22a of the second lower frame 22 and the second lower rail 27a of the second lower rail member 27 are arranged to overlap in the front-rear direction at the same height position.

[0044] As described above, in the display case 10 according to the present embodiment, the second upper frame 21 provided at the upper end portion of the second panel 2 is assembled to the upper base plate 37 via the second upper rail member 26, the upper slide shaft 42b, the upper bush 42a, and the upper fixing plate 40. Also, the second lower frame 22 provided at the lower end portion of the second panel 2 is assembled to the lower base plate 35 via the second lower rail member 27, the lower slide shaft 47b, the lower bush 47a, and the lower fixing plate 45.

[0045] In the above configuration, when the upper slide shaft 42b and the lower slide shaft 47b slide in the front-rear direction, the second panel 2 can be displaced in the thickness direction. In this way, the upper bush 42a and the upper slide shaft 42b, and the lower bush 47a and the lower slide shaft 47b function as a second panel displacement part that enables the second panel 2 to be displaced in the thickness direction.

[0046] Also, as shown in FIG. 6, the assembly configuration of the first panel 1 is substantially the same as that of the second panel 2. That is, behind the first panel 1, an upper bush 52a and an upper slide shaft 52b are assembled behind the upper base plate 37 via an upper fixing plate 50. The upper slide shaft 52b passes through the upper bush 52a, the upper fixing plate 50, and the upper base plate 37 and is slidable in the front-rear direction.

[0047] A first upper rail member 16 extending in the left-right direction is fixed to the front end portion of the upper slide shaft 52b. A groove-shaped first upper rail 16a that opens forward is formed in the first upper rail member 16. The first upper rail 16a functions as the first main rail according to the present invention.

[0048] A first upper open holder 51, which is a permanent electromagnetic holder, is provided outside the upper bush 52a. Also, a first upper closed holder 54, which is also a permanent electromagnetic holder, is provided on the front surface of the upper base plate 37.

[0049] In the present embodiment, a first upper open plate 53, which is a steel plate, is fixed to the rear end portion of the upper slide shaft 52b. The first upper open holder 51 is configured to adsorb the first upper open plate 53 with a permanent magnet when not energized, and not to adsorb the first upper open plate 53 when energized.

[0050] Also, as shown in FIG. 6, a lower bush 57a and a lower slide shaft 57b are assembled behind the lower base plate 35 via a lower fixing plate 55. The lower slide shaft 57b passes through the lower bush 57a, the lower fixing plate 55, and the lower base plate 35 and is slidable in the front-rear direction.

[0051] At the front end of the lower slide shaft 57b, a first lower rail member 17 extending in the left-right direction is fixed. A groove-shaped first lower rail 17a opening forward is formed in the first lower rail member 17. The first lower rail 17a functions as the first main rail according to the present invention.

[0052] At the rear part outside the lower bush 57a, a first lower open holder 56 which is a permanent magnet holder is provided. Also, on the front surface of the lower base plate 35, a first lower closed holder 59 which is also a permanent magnet holder is provided.

[0053] In the present embodiment, a first lower open plate 58 which is a steel plate is fixed to the rear end of the lower slide shaft 57b. The first lower open holder 56 is configured to adsorb the first lower open plate 58 by a permanent magnet when not energized and not adsorb the first lower open plate 58 when energized.

[0054] As shown in FIG. 6, the first panel 1 is supported by the first upper rail member 16 and the first lower rail member 17. Specifically, the first panel 1 is configured such that a first glass plate 13 having transparency is supported by a first upper frame 11 and a first lower frame 12. When the first panel 1 is in a closed state, a seal member P is inserted between the first glass plate 13, the lower base plate 35, and the upper base plate 37.

[0055] A groove-shaped first upper groove 11a opening forward is formed in the first upper frame 11. Also, a groove-shaped first lower groove 12a opening forward is formed in the first lower frame 12. The first upper groove 11a and the first lower groove 12a function as the second sub-rails according to the present invention. In the present embodiment, the second sub-rail and the second main rail described above are collectively referred to as the "second rail" on which the above-described second rollers (second upper roller 24 and second lower roller 25) roll.

[0056] At the rear of the first upper frame 11, an upper support piece 11b extending downward is formed, and a first upper closing plate 18 which is a steel plate is fixed to the rear surface of the upper support piece 11b. The first upper closing holder 54 is configured to adsorb the first upper closing plate 18 by a permanent magnet when the first panel 1 is in the non-energized closed state, and not to adsorb the first upper closing plate 18 when energized.

[0057] Also, at the rear of the first lower frame 12, a lower support piece 12b extending upward is formed, and a first lower closing plate 19 which is a steel plate is fixed to the rear surface of the lower support piece 12b. The first lower closing holder 59 is configured to adsorb the first lower closing plate 19 by a permanent magnet when the first panel 1 is in the non-energized closed state, and not to adsorb the first lower closing plate 19 when energized.

[0058] On the rear surface of the first upper groove 11a in the first upper frame 11, three first upper rollers 14 extending rearward are provided (see FIG. 1). The first upper rollers 14 are inserted into the inside of the first upper rail member 16 so as to be rollable on the first upper rail 16a. That is, the first upper groove 11a of the first upper frame 11 and the first upper rail 16a of the first upper rail member 16 are arranged to overlap in the front-rear direction at the same height position.

[0059] Also, on the rear surface of the first lower groove 12a in the first lower frame 12, three first lower rollers 15 extending rearward are provided (see FIG. 1). The first lower rollers 15 are inserted into the inside of the first lower rail member 17 so as to be rollable on the first lower rail 17a. That is, the first lower groove 12a of the first lower frame 12 and the first lower rail 17a of the first lower rail member 17 are arranged to overlap in the front-rear direction at the same height position.

[0060] As described above, in the display case 10 according to the present embodiment, the first upper frame 11 provided at the upper end portion of the first panel 1 is assembled to the upper base plate 37 via the first upper rail member 16, the upper slide shaft 52b, the upper bush 52a, and the upper fixing plate 50. Also, the first lower frame 12 provided at the lower end portion of the first panel 1 is assembled to the lower base plate 35 via the first lower rail member 17, the lower slide shaft 57b, the lower bush 57a, and the lower fixing plate 55.

[0061] In the above configuration, when the upper slide shaft 52b and the lower slide shaft 57b slide in the front-rear direction, the first panel 1 can be displaced in the thickness direction. In this way, the upper bush 52a and the upper slide shaft 52b, and the lower bush 57a and the lower slide shaft 57b function as a first panel displacement part that enables the first panel 1 to be displaced in the thickness direction.

[0062] As shown in FIGS. 1, 3, and 4(a), the second panel 2 is arranged on the same plane as the first panel 1 adjacent to the right side of the first panel 1 in a closed state, and as shown in FIGS. 4(b) and 5, it is in a movable state displaced forward from the closed state, and as shown in FIGS. 2, 4(c), and 6, it can be displaced between an open state where it slides and displaces leftward from the movable state and is arranged overlapping the first panel 1 in the front-rear direction in a front view.

[0063] When displacing the second panel 2 in the closed state to the movable state, first, the second upper closing holder 44 and the second lower closing holder 49 are energized to release the adsorption of the second upper closing plate 28 and the second lower closing plate 29. Then, as shown in FIG. 2, a handle H is attached to the second panel 2, and the user pulls it forward in the direction opposite to the display space S as indicated by the arrow in FIG. 4(a). As a result, as shown in FIGS. 4(b) and 5, the second panel 2 is displaced forward to be in the movable state. At this time, the second upper opening holder 41 and the second lower opening holder 46 adsorb the second upper opening plate 43 and the second lower opening plate 48.

[0064] When the second panel 2 is displaced to the movable state, the second main rail and the second sub-rail constituting the second rail communicate with each other. Specifically, as shown in FIG. 4(b), when the second upper rail member 26 is displaced forward together with the second panel 2 so that the front-rear positions coincide with the first upper frame 11, the second upper rail 26a and the first upper groove 11a communicate with each other. Similarly, when the second lower rail member 27 is displaced forward together with the second panel 2 so that the front-rear positions coincide with the first lower frame 12, the second lower rail 27a and the first lower groove 12a communicate with each other.

[0065] When the second main rail and the second sub-rail communicate with each other, as shown by the arrow in Fig. 4(b), the second panel 2 can be slid and displaced from the movable state in the width direction (left side) toward the first panel 1. That is, as shown in Figs. 4(c) and 6, the second upper roller 24 rolls on the first upper groove 11a, and the second lower roller 25 rolls on the first lower groove 12a, so that the second panel 2 is displaced to an open state where it overlaps the first panel 1 in a front view.

[0066] When displacing the movable second panel 2 to the closed state, first, the second upper open holder 41 and the second lower open holder 46 are energized to release the adsorption of the second upper open plate 43 and the second lower open plate 48. Then, the user pushes the second panel 2 backward in the direction of the display space S. As a result, as shown in Figs. 3 and 4(a), the second panel 2 is displaced backward to the closed state.

[0067] As described above, in the display case 10 according to the present embodiment, when the second panel 2 is in the open state, the second panel 2 is configured to be supported by the first upper frame 11 and the first lower frame 12 of the first panel 1. Therefore, the second panel 2 can be completely opened and disposed in front of the first panel 1. That is, according to the display case 10 according to the present embodiment, the front surface is flat in the closed state, and the entire surface of the second panel 2 can be opened in the open state.

[0068] Also, in the display case 10 according to the present embodiment, the first upper groove 11a and the first lower groove 12a, which are the second sub-rails, are provided over the entire width direction of the first panel 1. Thereby, since the second panel 2 in the open state can be displaced over the entire width direction of the first panel 1, the movable range of the second panel 2 can be increased.

[0069] Also, in the display case 10 according to the present embodiment, the first panel 1 and the second panel 2 are formed to have the same width dimension. Thereby, the first panel 1 and the second panel 2 can be overlapped in the width direction.

[0070] In addition, in the display case 10 according to the present embodiment, it is also possible to provide a cover that shields part or all of the front surfaces of the first upper groove 11a and the first lower groove 12a, which are the second sub-rails. As a result, the first upper groove 11a and the first lower groove 12a are not visible in a front view, so the design of the display case 10 can be improved.

[0071] In addition, in the display case 10 according to the present embodiment, it is also possible to provide a regulating member that regulates the rolling of the second rollers (the second upper roller 24 and the second lower roller 25) in the first upper groove 11a and the first lower groove 12a, which are the second sub-rails. Thereby, since the rolling range of the second rollers in the second sub-rail can be regulated, it is possible to prevent the second panel 2 from coming out of the second sub-rail.

[0072] In addition, in the display case 10 according to the present embodiment, the second panel 2 is displaced from the closed state to the movable state by attaching a handle H to the surface and pulling it in the direction opposite to the display space S. Thereby, it becomes possible to easily displace the second panel 2 from the closed state to the movable state.

[0073] In the display case 10 according to the present embodiment, the assembly configuration of the first panel 1 is substantially the same as that of the second panel 2. Therefore, contrary to the above configuration, it is also possible to displace the first panel 1 from the closed state to the movable state and the open state.

[0074] When displacing the first panel 1 in the closed state shown in Fig. 7(a) to the movable state, first, the first upper closing holder 54 and the first lower closing holder 59 are energized to release the adsorption of the first upper closing plate 18 and the first lower closing plate 19. Then, a handle H is attached to the first panel 1, and the user pulls it forward in the direction opposite to the display space S as shown by the arrow in Fig. 7(a). As a result, as shown in Fig. 7(b), the first panel 1 is displaced forward to become a movable state. At this time, the first upper opening holder 51 and the first lower opening holder 56 adsorb the first upper opening plate 53 and the first lower opening plate 58.

[0075] When the first panel 1 is displaced to the movable state, the first main rail and the first sub-rail that constitute the first rail communicate with each other. Specifically, when the first upper rail member 16 is displaced forward together with the first panel 1 and the front-rear positions coincide with the second upper frame 21, the first upper rail 16a and the second upper groove 21a communicate with each other. Similarly, when the first lower rail member 17 is displaced forward together with the first panel 1 and the front-rear positions coincide with the second lower frame 22, the first lower rail 17a and the second lower groove 22a communicate with each other.

[0076] When the first main rail and the first sub-rail communicate with each other, as shown by the arrow in Fig. 7(b), the first panel 1 can be slid and displaced in the width direction (right side) from the movable state to the side of the second panel 2. That is, as shown in Fig. 7(c), when the first upper roller 14 rolls in the second upper groove 21a and the first lower roller 15 rolls in the second lower groove 22a, the first panel 1 is displaced to the open state where it overlaps the second panel 2 in the front view.

[0077] In addition, in the display case 10 according to the present embodiment, it is also possible to slide and displace the first panel 1 or the second panel 2 from the movable state in the direction of the other panel 3. That is, the first panel 1 or the second panel 2 can also be displaced to the open state where it overlaps the other panel 3 in the front view.

[0078] Further, in the display case 10 according to the present embodiment, in the second panel 2, the second rollers (the second upper roller 24 and the second lower roller 25) and the second upper groove 21a and the second lower groove 22a which are the first sub-rails are provided at the same height position. Also, the second rollers are arranged on the display space side of the first sub-rail.

[0079] Similarly, in the first panel 1, the first rollers (the first upper roller 14 and the first lower roller 15) and the first upper groove 11a and the first lower groove 12a which are the second sub-rails are provided at the same height position. Also, the first rollers are arranged on the display space side of the second sub-rail.

[0080] In the display case 10 according to the present embodiment, by configuring as described above, when the first panel 1 or the second panel 2 is opened, as shown in FIG. 6, the second upper groove 21a and the second lower groove 22a, which are the first sub-rails, and the first upper groove 11a and the first lower groove 12a, which are the second sub-rails, can be opened in a superimposed state.

[0081] [Modification Example] The above embodiment can be appropriately modified as shown in the following modification examples. Each modification example may be applied in combination with other modification examples as long as there is no contradiction.

[0082] In the display case 10 according to the present embodiment, rails and rollers are provided on both the upper and lower sides of the first panel 1 and the second panel 2, but it is also possible to configure such that the rails and rollers are provided only on the upper side or the lower side of the panel.

[0083] Also, it is possible to make only one of the first panel 1 and the second panel 2 a movable panel and the other a fixed panel. In this case, it is also possible to configure the fixed panel with an opaque plate material. Further, it is also possible to configure the other panel 3 in the display case 10 according to the present embodiment like the first panel 1 or the second panel 2 and provide a configuration with three or more movable panels.

[0084] Also, it is possible to configure such that the first upper groove 11a and the first lower groove 12a, which are the second sub-rails of the first panel 1 (the same applies to the second panel 2, the same hereinafter), are provided only in a part in the width direction of the first panel 1. Also, it is possible to form the first panel 1 and the second panel 2 in different widths.

[0085] Also, it is possible to configure such that a cover for shielding the first upper groove 11a and the first lower groove 12a, which are the second sub-rails, is not provided. Also, it is possible to configure such that a regulating member for regulating the rolling of the second roller is not provided in the first upper groove 11a and the first lower groove 12a, which are the second sub-rails.

[0086] In addition, in the display case 10 according to the present embodiment, the forward and backward movement and the lateral sliding displacement of the first panel 1 and the second panel 2 are manually performed by attaching the handle H. However, these displacements can also be performed by electric control or hydraulic control.

[0087] In the display case 10 according to the present embodiment, the displacement of the first panel 1 or the second panel 2 is regulated by the permanent magnet holder. However, as a configuration for regulating the displacement, in addition to the permanent magnet holder, it is also possible to include an electromagnet, a solenoid, or a motor. Further, when using the permanent magnet holder, it is also possible to configure it to suppress the movement of the first panel 1 or the second panel 2 when energized and allow the movement when not energized.
