DETAILED DESCRIPTION OF THE INVENTION

[0028] A display case 10 according to one embodiment of the present invention will be described below with reference to Figures 1 to 5. The display case 10 is a box-shaped device for housing and displaying exhibits in, for example, an art gallery or museum.

[0029] As shown in Figures 1 and 2, the display case 10 according to this embodiment comprises a top panel 1, a bottom panel 2, two opposing side panels 3, 3, and a movable side panel 4 that can open and close an opening formed by the top panel 1, bottom panel 2, and two side panels 3, 3. In this embodiment, the side of the display case 10 on which the movable side panel 4 is provided is referred to as the front of the display case 10. As shown in Figure 3, the display case 10 according to this embodiment also has a side panel 3 on the rear side opposite the movable side panel 4. The display case 10 maintains its internal airtightness by inserting a sealant between the adjacent top panel 1, bottom panel 2, and side panels 3.

[0030] In the display case 10, the top plate 1, each side plate 3, and movable side plate 4 are made of transparent glass panels, allowing the exhibits inside to be seen from the outside. Opaque masking portions 3a and 4a are formed on the lower ends of the side plate 3 and movable side plate 4. As shown in Figures 1 and 2, the bottom plate 2 is placed on the upper surface of the support portion 5. In other words, the support portion 5 is a member provided at the lower end of the display case 10 and supports the display case 10.

[0031] The display case 10 according to this embodiment is formed with a height dimension of 2 m or more. In other words, in this embodiment, the top panel 1 is positioned at a height of 2 m or more from the installation surface of the display case 10. As shown in Figures 3 and 4, the top panel 1 and each side panel 3 are assembled to each other via a metal frame member 11 and an L-shaped connecting member 12. The top panel 1 is provided with lighting 14 and spot lighting 15 for illuminating the exhibits housed inside the display case 10.

[0032] A humidity control section 7 is provided inside the display case 10 according to this embodiment to adjust the humidity of the air inside the display case 10. The humidity control section 7 includes a humidity control device 71 housed inside the housing, an air intake section 72 that draws air from inside the display case 10 into the humidity control device 71, an air supply section 73 that supplies air from the humidity control device 71 to the inside of the display case 10, and a detection section 74 that detects the humidity and temperature inside the display case 10.

[0033] In the display case 10 according to this embodiment, a metal top frame 13 is provided on the edge of the opening side (front side) of the top plate 1. As shown in Figures 4 and 5, an engagement groove 13a with a semi-cylindrical inner circumferential surface is formed along the longitudinal direction at the front end of the top surface of the top frame 13.

[0034] Meanwhile, a side frame 41 is provided on the upper edge of the movable side plate 4. A semi-cylindrical engagement protrusion 41a is formed along the longitudinal direction on the side edge of the side frame 41 on the side (rear side) of the top plate 1. Then, as shown in Figures 4 and 5, by inserting the engagement protrusion 41a into the engagement groove 13a, the side frame 41 is assembled to the top frame 13 so that it can rotate around an axis extending in the longitudinal direction of the top frame 13 and slide in the longitudinal direction of the top frame 13.

[0035] In this embodiment, the movable side panel 4 moves close to the opening and assumes a closed state as shown in Fig. 4 when the side frame 41 rotates downward relative to the top frame 13. Also, the movable side panel 4 moves upward relative to the top frame 13 when the side frame 41 rotates upward relative to the top frame 13, and assumes an open state away from the opening as shown in Fig. 5. In other words, the movable side panel 4 can be displaced between a closed state and an open state by rotating the side frame 41 relative to the top frame 13.

[0036] In this embodiment, as shown in Figures 2 to 5, a gasket 6 is provided on the front surface 13b of the top frame 13 and on the front end surfaces of the side plates 3 and 3 on both the left and right sides and the bottom plate 2, and abuts against the movable side plate 4 when the movable side plate 4 is in the closed state.

[0037] As described above, the display case 10 according to this embodiment is configured so that the packing 6 directly contacts the movable side panel 4 in the closed state. As a result, even if an impact occurs to the movable side panel 4, the impact can be absorbed directly by the packing 6 without going through the side frame 41, and the impact on the movable side panel 4 can be sufficiently alleviated by the packing 6.

[0038] Furthermore, in the display case 10 according to this embodiment, the movable side panel 4 is made of a glass panel which may crack due to impact, but as described above, the impact on the movable side panel 4 can be adequately mitigated by the packing 6, which is preferable. Furthermore, in the display case 10 according to this embodiment, the top panel 1 is positioned at a height of 2 m or more above the installation surface of the display case 10, which is preferable because the impact on the movable side panel 4 can be adequately mitigated even when the movable side panel 4 is rotated at such a high position.

[0039] Furthermore, according to the display case 10 of this embodiment, as described above, the packing 6 is configured to directly contact the movable side plate 4, so even if a gap occurs between the movable side plate 4 and the side frame 41, the high sealing performance of the packing 6 can be maintained. In other words, a decrease in the sealing performance between the movable side plate 4 and the packing 6 can be suppressed.

[0040] 2, in the display case 10 according to this embodiment, when the movable side panel 4 is in the open state, the side frame 41 slides longitudinally relative to the top frame 13, allowing the movable side panel 4 to be displaced laterally relative to the top panel 1. This allows the opening to be opened widely by displacing the movable side panel 4 laterally, making it easy to put exhibits in and take them out of the display case 10. Furthermore, by displacing the movable side panel 4 laterally, the movable side panel 4 can be attached to and detached from the top panel 1.

[0041] 2, with the display case 10 according to this embodiment, the engaging ridges 41a of the side frames 41 are inserted into the engaging grooves 13a of the top frame 13, or the engaging ridges 41a extend outward in the longitudinal direction of the top frame 13 from the engaging grooves 13a, thereby enabling the side frames 41 to slide longitudinally relative to the top frame 13. In other words, by configuring the engaging ridges 41a of the side frames 41 and the engaging grooves 13a of the top frame 13 as sliding members, the configuration for lateral displacement of the movable side panels 4 relative to the top panel 1 can be simplified.

[0042] Furthermore, in the display case 10 according to this embodiment, the packing 6 is continuously provided along the opening on the front surface 13b of the top frame 13 and on the front end surfaces of the side panels 3, 3 on both the left and right sides and the bottom panel 2. This ensures the overall sealing performance of the display case 10.

[0043] 4 and 5, in the display case 10 according to this embodiment, the side frames 41 are formed with a smaller vertical width than the top frame 13. The packing 6 is provided on the front side surface 13b of the top frame 13, which is the side surface on the movable side panel 4 side. This prevents interference between the packing 6 and the side frames 41.

[0044] [Variations] The above embodiment can be modified as appropriate as shown in the following modifications. Each modification may be applied in combination with other modifications as long as no contradiction occurs.

[0045] In the display case of the present invention, it is also possible to configure the side frames so that they cannot be displaced longitudinally relative to the top frame. In other words, the display case can be opened and closed only by rotating the movable side panels. Furthermore, in the display case of the present invention, the configuration in which the side frames are displaced longitudinally relative to the top frame can also be configured using methods other than inserting the engaging protrusions into the engaging grooves.

[0046] The display case according to the present invention may be configured without a humidity control unit. Also, if it is not necessary to maintain high airtightness of the display case, it may be configured so that the packing is not provided continuously along the opening, but only between the movable side panel and the top frame.
