DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] (One embodiment) 1. Overview A display device 1 according to an embodiment shown in FIG. 1 includes a display panel 2 and a support mechanism 3 that supports the panel 2 so as to be movable between a vertical position parallel to the vertical direction and an inclined position inclined with respect to the vertical direction. The support mechanism 3 includes a first support 4 provided on the panel 2, a second support 5 provided on the ceiling 10 side, an upper shaft 6 connecting the first support 4 and the second support 5, and a lower shaft 7 located below the upper shaft 6 and connecting the first support 4 and the second support 5. One of the first support 4 and the second support 5 is provided with an upper guide groove 8 into which the upper shaft 6 is inserted and a lower guide groove 9 into which the lower shaft 7 is inserted. The upper guide groove 8 and the lower guide groove 9 are configured such that the upper shaft 6 moves along the upper guide groove 8 and the lower shaft 7 moves along the lower guide groove 9, thereby moving the panel 2 between the vertical position and the inclined position.

[0011] The support mechanism 3 of the embodiment shown in FIG. 1 supports the display panel unit 2 so as to be movable between a vertical position parallel to the vertical direction and an inclined position inclined with respect to the vertical direction. The support mechanism 3 has a first support part 4 fixed to the panel unit 2, a second support part 5 fixed to the ceiling 10 side, an upper shaft part 6 connecting the first support part 4 and the second support part 5, and a lower shaft part 7 located below the upper shaft part 6 and connecting the first support part 4 and the second support part 5. One of the first support part 4 and the second support part 5 is provided with an upper guide groove 8 into which the upper shaft part 6 is inserted and a lower guide groove 9 into which the lower shaft part 7 is inserted. The upper guide groove 8 and the lower guide groove 9 are configured so that the upper shaft part 6 moves along the upper guide groove 8 and the lower shaft part 7 moves along the lower guide groove 9, thereby moving the panel unit 2 between the vertical position and the inclined position.

[0012] In the display device 1 and support mechanism 3 of one embodiment having the above configuration, for example, when a passerby's baggage or the like collides with the panel unit 2, the upper shaft portion 6 moves along the upper guide groove 8 and the lower shaft portion 7 moves along the lower guide groove 9. This allows the panel unit 2 to move from a vertical position to an inclined position. Therefore, the display device 1 and support mechanism 3 of one embodiment can deflect the external force applied when colliding with a passerby's baggage or the like, and can suppress the occurrence of defects such as deformation in the support mechanism 3.

[0013] 2.Details Next, the display device 1 and the support mechanism 3 according to an embodiment will be described in more detail with reference to the drawings. As shown in Fig. 2, the display device 1 is installed on a ceiling 10 in a station, for example, and functions as a guide sign indicating the direction to the restrooms.

[0014] The display device 1 comprises a long panel unit 2 having letters, figures, symbols, etc. on its surface, a long housing 11 attached to a ceiling panel 100 that constitutes a ceiling 10, and a support mechanism 3 (see Figure 1) that connects the panel unit 2 and the housing 11.

[0015] The display device 1 further includes an illumination device that illuminates the panel unit 2 with light, and a power supply unit that supplies power to the lighting device. In this embodiment, the display device 1 is a light-guiding device that guides light from the lighting device into the panel unit 2, causing the entire panel unit 2 to emit light. In the following description, when directions such as up, down, and horizontal are used, they are based on a state in which the display device 1 is installed on the ceiling 10 and the panel unit 2 is in a vertical position parallel to the vertical direction (hereinafter simply referred to as the "installed state").

[0016] 2-1.Case 1 and 2, the housing 11 has a bottom plate portion 110 having a long plate shape and a pair of side plate portions 111, 112 also having a long plate shape. The bottom plate portion 110 has a longitudinal direction D1 and a lateral direction D2. The longitudinal direction D1 and the lateral direction D2 are parallel to the ceiling 10, in other words, perpendicular to the up-down direction in the installed state. The longitudinal direction D1 and the lateral direction D2 are perpendicular to each other. The longitudinal direction D1 and the lateral direction D2 of the bottom plate portion 110 coincide with the longitudinal direction D1 and the lateral direction D2 of the housing 11 as a whole.

[0017] The pair of side plate portions 111, 112 extend downward from both end portions in the short side direction D2 of the bottom plate portion 110. The pair of side plate portions 111, 112 form an accommodation space 113 between themselves and the bottom plate portion 110. The accommodation space 113 is a space in which the support mechanism 3 is accommodated, and is open downward.

[0018] The pair of side plate portions 111, 112 have a slightly V-shaped opening so that the lower portions are spaced apart from each other. The lower portion of the accommodation space 113 has a larger horizontal cross section.

[0019] The housing 11 further has a pair of flanges 114, 115 extending from the tips (lower ends) of the pair of side plate portions 111, 112. The pair of flange portions 114, 115 extend in directions away from each other. The direction in which each flange portion 114, 115 extends from the corresponding side plate portion 111, 112 is horizontal in the installed state.

[0020] The housing 11 is attached to the ceiling panel 100 via at least one mounting bracket 12 fixed to the back side of the ceiling panel 100. In this embodiment, the housing 11 is attached to the ceiling panel 100 via multiple mounting brackets 12 positioned at intervals in the longitudinal direction D1.

[0021] The housing 11 is installed on the ceiling 10 by fixing a central portion of the bottom plate portion 110 of the housing 11 in the short side direction D2 to the mounting bracket 12 with a fastener 13 formed of a bolt and a nut.

[0022] 2-2. Panel section In this embodiment, characters, figures, and symbols related to restrooms are provided on the display panel unit 2. As shown in Fig. 2, the characters on the panel unit 2 are the words "restroom" and "restrooms." The figures on the panel unit 2 are a pictogram and the international symbol mark (wheelchair mark) of the restroom. The symbol on the panel unit 2 is an arrow symbol indicating the direction of the restrooms.

[0023] The panel unit 2 is a generally rectangular plate. When in a vertical position, the panel unit 2 has a longitudinal direction parallel to the longitudinal direction D1 of the housing 11, a width direction parallel to the up-down direction, and a thickness direction parallel to the horizontal direction.

[0024] 1, the panel unit 2 has a first display surface 20 constituting one side surface in the thickness direction of the panel unit 2, and a second display surface 21 constituting the other side surface in the thickness direction of the panel unit 2. The first display surface 20 and the second display surface 21 are positioned at opposite sides in the thickness direction of the panel unit 2.

[0025] The panel unit 2 is a light-guiding panel, and has a structure in which a first light-guiding panel unit 22 and a second light-guiding panel unit 23 are stacked with a reflective sheet 24 sandwiched therebetween. Each of the first light-guiding panel unit 22 and the second light-guiding panel unit 23 is a transparent panel made of acrylic and having a thickness within a range of 3 mm to 4 mm, for example. The reflective sheet 24 is a white sheet made of, for example, polyethylene terephthalate.

[0026] The first display surface 20 of the panel unit 2 is formed by the surface of the first light guide panel unit 22, and the second display surface 21 is formed by the surface of the second light guide panel unit 23. The first display surface 20 and the second display surface 21 are each provided with similar characters, figures, and symbols related to the restroom. Note that characters, figures, and symbols related to the restroom may be provided on only one of the first display surface 20 and the second display surface 21. In addition, in this embodiment, all of the characters, figures, and symbols are provided on the panel unit 2, but this is not limited thereto, and it is sufficient that at least one of the characters, figures, and symbols is provided.

[0027] The panel unit 2 further includes a cover material 25 that covers the upper ends of the light guide panel units 22, 23. The cover material 25 is a substantially U-shaped member that opens downward, and covers the upper ends of the light guide panel units 22, 23 over their entire longitudinal lengths.

[0028] The cover material 25 has a long bottom plate portion that is long in the longitudinal direction of the panel portion 2, and a pair of side plate portions that extend downward from both ends of the bottom plate portion in the lateral direction. The cover material 25 and the light guide panel portions 22, 23 are integrated together by fasteners such as bolts and nuts that penetrate the pair of side plate portions of the cover material 25 and the upper ends of the light guide panel portions 22, 23. A gap is formed between the bottom plate portion of the cover material 25 and the upper end faces of the light guide panel portions 22, 23.

[0029] 2-3. Irradiation device The illumination device is a device that illuminates light onto the panel unit 2. The illumination device includes a light source unit configured with an LED (Light Emitting Diode) unit. The light source unit is configured to illuminate the upper end surface of the panel unit 2 (i.e., the upper end surfaces of the light guide panel units 22 and 23) from above. The light source unit emits light using power supplied from a power supply unit installed in the housing 11.

[0030] The light emitted downward from the light source unit is incident on the upper end surfaces of the first light guide panel unit 22 and the second light guide panel unit 23, and is reflected by the reflective sheet 24, causing the first display surface 20 and the second display surface 21, which face opposite each other, to emit light approximately uniformly over their entire surfaces.

[0031] 2-4.Support mechanism The support mechanism 3 is a mechanism that supports the panel unit 2 so that it can move between a vertical position parallel to the vertical direction and an inclined position inclined to the vertical direction. Note that "parallel to the vertical direction" as described above is not limited to being strictly parallel, but also includes being approximately parallel with a slight inclination to the vertical direction. In this embodiment, the support mechanism 3 suspends the panel unit 2 from the center of the short-side direction D2 of the bottom plate portion 110 of the housing 11.

[0032] 1 and 3A to 3C, the support mechanism 3 has a first support part 4 provided on the panel part 2, a second support part 5 provided on the ceiling 10 side, an upper shaft part 6 connecting the first support part 4 and the second support part 5, and a lower shaft part 7 connecting the first support part 4 and the second support part 5. The lower shaft part 7 is located below the upper shaft part 6.

[0033] One of the first support portion 4 and the second support portion 5 (the first support portion 4 in this embodiment) is provided with an upper guide groove 8 into which the upper shaft portion 6 is inserted, and a lower guide groove 9 into which the lower shaft portion 7 is inserted. The upper guide groove 8 and the lower guide groove 9 are configured such that the upper shaft portion 6 moves along the upper guide groove 8 and the lower shaft portion 7 moves along the lower guide groove 9, thereby moving the panel portion 2 between a vertical position and an inclined position.

[0034] The support mechanism 3 further has an upper spacer 14 that reduces friction occurring between the upper shaft portion 6 and the edge of the upper guide groove 8, and a lower spacer 15 that reduces friction occurring between the lower shaft portion 7 and the edge of the lower guide groove 9.

[0035] More specifically, in this embodiment, the first support portion 4 is configured with a first support member 4a that is fixed with fasteners such as screws to the upper end portion of the panel portion 2. In this embodiment, the first support member 4a is formed of a metal plate such as a steel plate.

[0036] The first support member 4a has a flat supported portion 40 supported by the second support portion 5, and a fixing portion 41 which is integral with the supported portion 40 and to which the upper end portion of the panel portion 2 is fixed.

[0037] The fixing part 41 has a lower plate part 410 extending horizontally (longitudinal direction D1) from the lower end part of the supported part 40, a vertical plate part 411 extending upward from the tip of the lower plate part 410, and an upper plate part 412 extending horizontally (longitudinal direction D1) from the upper end part of the vertical plate part 411. One end part in the longitudinal direction of the upper end part of the panel part 2 (more specifically, one end part of the bottom plate part of the cover material 25) is fixed to the upper plate part 412 by a fastener such as a screw.

[0038] The upper guide groove 8 and the lower guide groove 9 each penetrate the flat supported portion 40 in its thickness direction (longitudinal direction D1). The upper guide groove 8 is a long hole extending in a straight line in the vertical direction. The lower guide groove 9 has a central opening 90 located directly below the upper guide groove 8, and a first long hole portion 91 and a second long hole portion 92 extending in opposite directions from the central opening 90. The first long hole portion 91 and the second long hole portion 92 are each located higher the closer they are to the central opening 90.

[0039] Each of the first long hole portion 91 and the second long hole portion 92 extends in an arc shape in a direction tilted upward from the horizontal direction from the central opening 90. Each of the first long hole portion 91 and the second long hole portion 92 has a constant width in the short side direction over the longitudinal direction.

[0040] The first long hole portion 91 and the second long hole portion 92 are provided symmetrically with respect to a vertical line passing through the center of the central opening 90. The center of the linear upper guide groove 8 is located on the vertical line passing through the center of the central opening 90. The upper guide groove 8 and the central opening 90 are located in the center of the supported portion 40 in the horizontal direction (short side direction D2).

[0041] The supported portion 40 has an arc-shaped guide surface 910 configured by the upper edge of the first long hole portion 91 of the lower guide groove 9, and an arc-shaped guide surface 920 configured by the upper edge of the second long hole portion 92. The horizontal distance between the guide surfaces 910, 920 is shorter the closer to the central opening 90.

[0042] The supported portion 40 further has an arc-shaped restricting surface 911 formed by the lower edge of the first long hole portion 91 of the lower guide groove 9, and an arc-shaped restricting surface 921 formed by the lower edge of the second long hole portion 92. The restricting surface 911 and the restricting surface 921 are connected to each other so as to protrude upward at the center of the lower guide groove 9 in the horizontal direction.

[0043] In this embodiment, the second support portion 5 is composed of a pair of second support members 5a, 5b fixed to the ceiling 10 side (more specifically, the housing 11). Each of the pair of second support members 5a, 5b has a flat support portion 50 that supports the first support member 4a, and a flat fixing portion 51 that is integral with the support portion 50 and is fixed to the ceiling 10 side (more specifically, the bottom plate portion 110 of the housing 11) with fixing devices 52 such as bolts and nuts. Each of the pair of second support members 5a, 5b is formed of a metal plate such as a steel plate.

[0044] In this embodiment, the support part 50 has a rectangular shape at the top and a tapered shape at the bottom that becomes narrower toward the bottom. The support part 50 has an upper fixing hole 500 through which the upper shaft part 6 is passed and fixed, and a lower fixing hole 501 through which the lower shaft part 7 is passed and fixed. The lower fixing hole 501 is located at the lower end part of the support part 50. The upper fixing hole 500 is located directly above the lower fixing hole 501. The fixing holes 500, 501 are screw holes.

[0045] The fixing portion 51 extends from the upper end of the support portion 50 in a direction (longitudinal direction D1) perpendicular to the support portion 50. The fixing portion 51 is provided with a pair of fixing holes 510 through which the fixing tool 52 is inserted.

[0046] The pair of second support members 5a, 5b are integrated by stacking the fixing portions 51 vertically and inserting fasteners 52 into the pair of fixing holes 510 of both fixing portions 51. In the integrated state, a gap slightly larger than the thickness of the supported portion 40 of the first support member 4a is formed between the supporting portions 50 of the second support members 5a, 5b. In this state, the upper and lower fixing holes 500, 501 of the supporting portion 50 of one second support member 5a and the upper and lower fixing holes 500, 501 of the supporting portion 50 of the other second support member 5b are positioned one-to-one in the horizontal direction (longitudinal direction D1).

[0047] In this embodiment, the fixing portions 51 of the pair of second support members 5a, 5b are also fixed to the center of the short direction D2 of the bottom plate portion 110 of the housing 11 by a pair of fasteners 52 that integrate the fixing portions 51 of the pair of second support members 5a, 5b.

[0048] In this embodiment, the upper shaft portion 6 is a separate member from the support portions 4 and 5 (support members 4a, 5a, and 5b). The upper shaft portion 6 is composed of a bolt 60. The bolt 60 has a shaft portion 600 having a helical thread groove on its outer circumferential surface, and a head portion 601 having an outer dimension larger than that of the shaft portion 600.

[0049] In this embodiment, the lower shaft portion 7 is a separate member from the support portions 4 and 5 (support members 4a, 5a, and 5b). The lower shaft portion 7 is composed of a bolt 70. The bolt 70 has a shaft portion 700 having a helical thread groove on its outer circumferential surface, and a head portion 701 having an outer dimension larger than that of the shaft portion 700.

[0050] The upper spacer 14 is a member that reduces friction occurring between the upper shaft portion 6 and the edge of the upper guide groove 8. In this embodiment, the upper spacer 14 is cylindrical. In this embodiment, the upper spacer 14 is made of metal.

[0051] The inner diameter of the upper spacer 14 is equal to or larger than the diameter of the shaft portion 600 of the bolt 60 of the upper shaft portion 6. The outer diameter of the upper spacer 14 is equal to or smaller than the groove width of the upper guide groove 8 and larger than the diameter of the upper fixing hole 500. The axial length of the upper spacer 14 is slightly longer than the thickness of the supported portion 40 and equal to or slightly shorter than the distance between the support portions 50 of the pair of second support members 5a, 5b. The upper spacer 14 is disposed in the upper guide groove 8, and the shaft portion 600 of the bolt 60 of the upper shaft portion 6 is passed through the upper spacer 14. This allows the upper spacer 14 to reduce friction generated between the upper shaft portion 6 and the edge of the upper guide groove 8.

[0052] The lower spacer 15 is a member that reduces friction occurring between the lower shaft portion 7 and the lower guide groove 9. In this embodiment, the lower spacer 15 is a cylindrical member. In this embodiment, the lower spacer 15 is made of metal.

[0053] The inner diameter of the lower spacer 15 is equal to or larger than the diameter of the shaft portion 700 of the bolt 70 of the lower shaft portion 7. The outer diameter of the lower spacer 15 is equal to or smaller than the groove width of the lower guide groove 9 and larger than the diameter of the lower fixing hole 501. The axial length of the lower spacer 15 is slightly longer than the thickness of the supported portion 40 and equal to or slightly shorter than the distance between the support portions 50 of the pair of second support members 5a, 5b. The lower spacer 15 is disposed in the lower guide groove 9, and the shaft portion 700 of the bolt 70 of the lower shaft portion 7 is passed through the lower spacer 15. This allows the lower spacer 15 to reduce friction generated between the lower shaft portion 7 and the edge of the lower guide groove 9.

[0054] The shaft portion 600 of the bolt 60 of the upper shaft portion 6 is passed through the upper fixing hole 500 of the second support member 5a, the upper spacer 14 in the upper guide groove 8 of the first support member 4a, and the upper fixing hole 500 of the second support member 5b. In addition, the shaft portion 700 of the bolt 70 of the lower shaft portion 7 is passed through the lower fixing hole 501 of the second support member 5a, the lower spacer 15 in the lower guide groove 9 of the first support member 4a, and the lower fixing hole 501 of the second support member 5b.

[0055] As described above, the first support member 4a and the pair of second support members 5a, 5b are connected by the shafts 6, 7, so that the first support member 4a is movable relative to the pair of second support members 5a, 5b.

[0056] The panel portion 2 is fixed to the upper plate portion 412 of the fixing portion 41 of the first support member 4a so that the short side direction of the panel portion 2 is parallel to the central axis passing through the center of the upper guide groove 8 and the center of the central opening 90 of the lower guide groove 9.

[0057] In this embodiment, the display device 1 has a pair of support mechanisms 3 that suspend and support the panel unit 2. One first support member 4a is fixed to each of one end and the other end in the longitudinal direction of the panel unit 2 by the method described above.

[0058] 2-5.Other 1, the display device 1 of the present embodiment further includes a cover material 16 that covers the pair of support mechanisms 3. The cover material 16 is a substantially U-shaped member that opens downward. The cover material 16 has a bottom plate portion 160 that is long in the longitudinal direction D1 of the housing 11, and a pair of side plate portions 161 that extend downward from both ends of the bottom plate portion 160 in the width direction. A first support member 4a (first support portion 4) of the pair of support mechanisms 3 moves in the space inside the cover material 16.

[0059] 2-6. Display device operation In the display device 1 of this embodiment described above, under normal circumstances, that is, when a passerby's luggage or the like is not colliding with the thickness direction surface of the panel unit 2 and no external force of a predetermined level or more is being applied to the panel unit 2, the panel unit 2 is suspended and supported in a vertical position, as shown in FIG. 1.

[0060] When the panel portion 2 is in a vertical position, the weight of the panel portion 2 causes the shaft portion 600 of the upper shaft portion 6 to abut against the upper edge and a pair of side edges of the upper guide groove 8 in the supported portion 40 via the upper spacer 14. Also at this time, the shaft portion 700 of the lower shaft portion 7 abuts against the upper edge of the central opening 90 of the lower guide groove 9 in the supported portion 40 and the upper edges (guide surfaces 910, 920) of the long hole portions 91, 92 via the lower spacer 15.

[0061] Therefore, even if the thickness direction surface (display surfaces 20, 21) of the vertically oriented panel portion 2 is exposed to wind, the movement of the panel portion 2 is restricted by a pair of side edges of the upper guide groove 8 and the guide surfaces 910, 920, so that the panel portion 2 can maintain its vertical position.

[0062] In the display device 1 of this embodiment, when a passerby's baggage or the like collides with the thickness direction surface (display surfaces 20, 21) of the panel unit 2 and an external force of a predetermined level or more is applied, the panel unit 2 can move from the vertical position to an inclined position. Also, in the display device 1 of this embodiment, when a strong wind hits the thickness direction surface (display surfaces 20, 21) of the panel unit 2 and an external force of a predetermined level or more is applied, the panel unit 2 can move from the vertical position to an inclined position.

[0063] Specifically, when a predetermined or greater external force is applied to the second display surface 21 of the panel unit 2 in the vertical position, as shown in Fig. 4A, the upper edge (guide surface 920) of the second long hole portion 92 of the first support member 4a rides up onto the lower spacer 15 surrounding the shaft portion 700 of the lower shaft portion 7. Then, the shaft portion 700 of the lower shaft portion 7 approaches the outer edge (the edge opposite to the central opening 90) of the second long hole portion 92, and the shaft portion 600 of the upper shaft portion 6 approaches the lower edge of the upper guide groove 8 of the first support member 4a. As a result, the panel unit 2 in the vertical position moves to an inclined position, and part of the external force acting on the panel unit 2 can be deflected.

[0064] When the external force applied to the panel portion 2 is released, the weight of the panel portion 2 causes the upper shaft portion 6 to approach the upper edge of the upper guide groove 8, and the lower shaft portion 7 to approach the central opening 90 of the lower guide groove 9. This allows the panel portion 2 to automatically return to the vertical position shown in FIG.

[0065] Furthermore, when an external force of a predetermined magnitude or more is applied to the first display surface 20 of the panel unit 2 in the vertical position, as shown in Fig. 4B, the upper edge (guide surface 910) of the first long hole portion 91 of the first support member 4a rides up onto the lower spacer 15 surrounding the shaft portion 700 of the lower shaft portion 7. Then, the shaft portion 700 of the lower shaft portion 7 approaches the outer edge (the edge opposite to the central opening 90) of the first long hole portion 91, and the shaft portion 600 of the upper shaft portion 6 approaches the lower edge of the upper guide groove 8 of the first support member 4a. As a result, the panel unit 2 in the vertical position moves to an inclined position, and part of the external force acting on the panel unit 2 can be deflected.

[0066] When the external force applied to the panel portion 2 is released, the weight of the panel portion 2 causes the upper shaft portion 6 to approach the upper edge of the upper guide groove 8, and the lower shaft portion 7 to approach the central opening 90 of the lower guide groove 9. This allows the panel portion 2 to automatically return to the vertical position shown in FIG.

[0067] 2-7.Effects In the display device 1 of the present embodiment described above, when a passerby's baggage or the like collides with the panel unit 2, the upper shaft portion 6 moves along the upper guide groove 8 and the lower shaft portion 7 moves along the lower guide groove 9, thereby allowing the panel unit 2 to move from a vertical position to an inclined position. Therefore, in the display device 1 of the present embodiment, when a passerby's baggage or the like collides with the panel unit 2, the panel unit 2 moves from a vertical position to an inclined position, and the panel unit 2 can deflect the external force applied to the panel unit 2, thereby preventing the support mechanism 3 from being deformed or otherwise defective.

[0068] Furthermore, in the display device 1 of this embodiment, the panel unit 2 moves around two axes, the axis sections 6 and 7. Therefore, the force required to move the panel unit 2 is greater than when the panel unit 2 rotates around a single axis, making the panel unit 2 less likely to swing even when exposed to wind and easier to maintain a vertical position.

[0069] In addition, in the display device 1 of this embodiment, the long hole portions 91, 92 of the lower guide groove 9 extend in an arc shape from the central opening 90 in a direction inclined upward with respect to the horizontal direction. Therefore, in the vicinity of the central opening 90, the horizontal distance between the upper edges (guide surfaces 910, 920) of the long hole portions 91, 92 is narrow. Therefore, in the display device 1 of this embodiment, a large force is required for the guide surfaces 910, 920 to ride up onto the lower spacer 15 surrounding the shaft portion 700 of the lower shaft portion 7. As a result, in the display device 1 of this embodiment, the panel portion 2 in a vertical position is less likely to swing even when exposed to wind, and the vertical position is easily maintained.

[0070] In addition, in the display device 1 of this embodiment, the spacers 14, 15 are attached to the shafts 6, 7, and therefore the friction generated between the shafts 6, 7 and the edges of the guide grooves 8, 9 can be reduced by the spacers 14, 15. Therefore, in the display device 1 of this embodiment, the movement of the panel unit 2 about the two axes of the shafts 6, 7 can be easily and smoothly performed.

[0071] In addition, in the display device 1 of this embodiment, the distance between the supporting portions 50 of the pair of second supporting members 5a, 5b is set to be larger than the thickness of the supported portion 40 of the first supporting member 4a, so that it is possible to suppress the occurrence of friction between the first supporting member 4a and the pair of second supporting members 5a, 5b. Therefore, in the display device 1 of this embodiment, the panel unit 2 can be moved smoothly.

[0072] Furthermore, in the display device 1 of this embodiment, the upper guide groove 8 is a long hole extending in a straight line in the vertical direction, so that the upper shaft portion 6 can easily move within the upper guide groove 8, and the panel portion 2 can easily move between a vertical position and an inclined position.

[0073] Moreover, the display device 1 of this embodiment has long holes 91, 92 extending in opposite directions from a central opening 90 of the lower guide groove 9. Therefore, in the display device 1 of this embodiment, even if an external force is applied to either one side or the other side in the thickness direction of the panel unit 2, the panel unit 2 can be moved from a vertical position to an inclined position, and the external force can be easily deflected.

[0074] Furthermore, in the display device 1 of the present embodiment, the guide grooves 8, 9 are provided in the first support member 4a, which makes it easier to manufacture than a display device in which the guide grooves 8, 9 are provided in each of the pair of second support members 5a, 5b.

[0075] 3. Variations Next, a description will be given of modifications of the above-mentioned display device 1 and support mechanism 3. The modifications described below can be appropriately combined.

[0076] The support mechanism 3 is not limited to the structure shown in Figures 3A to 3C. The first support part 4 may be any one provided on the panel part 2, and is not limited to the first support member 4a which is a separate member from the panel part 2. For example, the first support part 4 may be one formed integrally with the panel part 2.

[0077] Furthermore, the second support portion 5 may be any member provided on the ceiling 10 side, and is not limited to the pair of second support members 5a, 5b fixed to the bottom plate portion 110 of the housing 11. The second support portion 5 may be formed of a part of the housing 11, or may be formed of a member directly fixed to the ceiling 10. Furthermore, the second support portion 5 may be, for example, one of the pair of second support members 5a, 5b.

[0078] Furthermore, the upper shaft portion 6 and the lower shaft portion 7 need only connect the first support portion 4 and the second support portion 5, and are not limited to the bolts 60, 70 which are separate members from the support members 4a, 5a. The upper shaft portion 6 and the lower shaft portion 7 may be formed integrally with the first support portion 4 and the second support portion 5 on the side where the guide grooves 8, 9 are not provided.

[0079] In addition, at least the portions of the shaft portions 600, 700 of the upper shaft portion 6 and the lower shaft portion 7 that are inserted into the guide grooves 8, 9 may be round rod-shaped without thread grooves, in which case the spacers 14, 15 can be omitted.

[0080] Furthermore, the spacers 14, 15 may be any member capable of reducing friction between the shaft portions 6, 7 and the edges of the guide grooves 8, 9, and are not limited to cylindrical members surrounding the shaft portions 600, 700 of the shaft portions 6, 7. The spacers 14, 15 may be members attached to the edges of the guide grooves 8, 9, for example.

[0081] Furthermore, the guide grooves 8, 9 only need to be provided in one of the first support portion 4 and the second support portion 5, and are not limited to being provided in the first support portion 4, but may be provided in the second support portion 5. Furthermore, the guide grooves 8, 9 are not limited to being holes penetrating the supported portion 40 of the first support portion 4 in the thickness direction, and may be formed by a recess provided in the supported portion 40, or a pair of protrusions protruding from the supported portion 40.

[0082] 3A and the like, and may be configured such that the panel unit 2 moves between the vertical position and the inclined position by the upper shaft portion 6 moving along the upper guide groove 8 and the lower shaft portion 7 moving along the lower guide groove 9. However, the guide grooves 8 and 9 are preferably configured such that when the external force acting on the panel unit 2 is released, the panel unit 2 returns from the inclined position to the vertical position due to its own weight.

[0083] Each of the long hole portions 91, 92 of the lower guide groove 9 is not limited to an arc shape as long as it is formed so that the portion closer to the central opening 90 is positioned higher. For example, each of the long hole portions 91, 92 may be provided in a straight line.

[0084] Furthermore, the display device 1 of the embodiment described above is not limited to a light-guiding type device that guides light from an illumination device into the panel unit 2 to illuminate the entire panel unit 2. The display device 1 may be an external illumination type device that illuminates the display surfaces 20 and 21 of the panel unit 2 by a pair of illumination devices installed in the housing 11.

[0085] The display device 1 of the embodiment described above is a panel for displaying station information and has a function of a guide sign showing the direction and distance to facilities within the station, such as restrooms, but the function of the display device 1 is not limited to this. For example, the display device 1 may have a function of a gate sign showing information such as platform numbers, stops, and required travel time. The display device 1 may also have a function of a guide sign showing information on transfers and various facilities (station interior map, exit guide, platform guide, route map, etc.) in a concourse or the like.

[0086] Furthermore, the support mechanism 3 is not limited to the structure shown in FIGS. 3A to 3C, and may have a structure such as modified examples 1 to 5 shown in FIGS.

[0087] 3-1. Variation 1 5, the fixing portion 41 of the first supporting member 4a of the first supporting portion 4 is composed of only a lower plate portion 410, and does not have a vertical plate portion 411 or an upper plate portion 412. The lower plate portion 410 of this modification protrudes from the lower end portion of the supported portion 40 of the first supporting member 4a in the opposite direction to the lower plate portion 410 of the first embodiment. Note that the lower plate portion 410 may protrude in either direction in the longitudinal direction D1.

[0088] The panel portion 2 is fixed to the lower plate portion 410 with fasteners such as screws. Therefore, in the support mechanism 3 of the first modification, the panel portion 2 is suspended and supported below the support mechanism 3. In the support mechanism 3 of the first modification, the portion of the panel portion 2 that is fixed to the lower plate portion 410 is not limited to both ends of the panel portion 2 in the longitudinal direction, and may be a portion of the panel portion 2 other than both ends in the longitudinal direction.

[0089] 3-2. Variation 2 In the support mechanism 3 of variant example 2 shown in Figures 6A and 6B, the shape of the guide grooves 8, 9 of the first support part 4 (first support member 4a) is different from the shape of the guide grooves 8, 9 of the first support part 4 of the embodiment shown in Figure 3A.

[0090] As shown in FIG. 6A and FIG. 6B, the lower guide groove 9 of the first support portion 4 (first support member 4a) is a long hole extending in the vertical direction. The upper guide groove 8 has a central opening 80 located directly above the lower guide groove 9, and a first long hole portion 81 and a second long hole portion 82 extending in opposite directions from the central opening 80. The first long hole portion 81 and the second long hole portion 82 are located higher in the vicinity of the central opening 80, and extend in an arc shape from the central opening 80 in a direction inclined downward with respect to the horizontal direction. Each of the long hole portions 81 and 82 has a constant width in the short direction over the longitudinal direction. The supported portion 40 of the first support member 4a has guide surfaces 810 and 820 formed by the upper edges of the long hole portions 81 and 82.

[0091] In the support mechanism 3 of the second modification, as shown in Fig. 6A, when the panel portion 2 is in a vertical position, the upper spacer 14 surrounding the shaft portion 600 of the upper shaft portion 6 abuts against the upper edge of the central opening 80 of the upper guide groove 8 of the first support member 4a and against the guide surfaces 810, 820. Also at this time, the lower spacer 15 surrounding the shaft portion 700 of the lower shaft portion 7 abuts against the upper edge and a pair of side edges of the lower guide groove 9. As a result, the movement of the panel portion 2 in a vertical position is restricted even when it is exposed to wind, making it easier to maintain the vertical position.

[0092] When an external force of a predetermined magnitude or more is applied to the second display surface 21 of the panel portion 2 in the vertical position, as shown in Fig. 6B, the guide surface 810 of the first long hole portion 81 rides up onto the upper spacer 14 surrounding the shaft portion 600 of the upper shaft portion 6. Then, the shaft portion 600 of the upper shaft portion 6 approaches the outer edge of the first long hole portion 81 (the edge opposite the central opening 80), and the shaft portion 700 of the lower shaft portion 7 approaches the lower edge of the lower guide groove 9. As a result, the panel portion 2 in the vertical position moves to an inclined position, and part of the external force acting on the panel portion 2 can be deflected.

[0093] Furthermore, when an external force of a predetermined magnitude or greater is applied to the first display surface 20 of the panel portion 2 in the vertical position, the guide surface 820 of the second long hole portion 82 rides up onto the upper spacer 14 surrounding the shaft portion 600 of the upper shaft portion 6. Then, the shaft portion 600 of the upper shaft portion 6 approaches the outer edge of the second long hole portion 82, and the shaft portion 700 of the lower shaft portion 7 approaches the lower edge of the lower guide groove 9. As a result, the panel portion 2 in the vertical position moves to an inclined position, and some of the external force acting on the panel portion 2 can be deflected.

[0094] When the external force applied to the panel portion 2 is released, the weight of the panel portion 2 causes the upper shaft portion 6 to approach the central opening 80 of the upper guide groove 8, and the lower shaft portion 7 to approach the upper edge of the lower guide groove 9. This allows the panel portion 2 to automatically return to the vertical position shown in FIG. 6A.

[0095] 3-3. Variation 3 In the support mechanism 3 of the modified example 3 shown in Figures 7A and 7B, the shape of the upper guide groove 8 of the first support part 4 (first support member 4a) is different from the shape of the upper guide groove 8 of the first support part 4 of the embodiment shown in Figure 3A.

[0096] 7A and 7B, the upper guide groove 8 has a central opening 80 located directly above the central opening 90 of the lower guide groove 9, and a first long hole portion 81 and a second long hole portion 82 extending in opposite directions from the central opening 80. Each of the first long hole portion 81 and the second long hole portion 82 is located higher the closer they are to the central opening 80, and is arc-shaped. Each of the long hole portions 81, 82 has a constant width in the short direction over the longitudinal direction.

[0097] In the support mechanism 3 of the third modified example, as shown in Fig. 7A, when the panel section 2 is in a vertical position, the upper spacer 14 surrounding the shaft section 600 of the upper shaft section 6 abuts against the upper edge of the central opening 80 of the upper guide groove 8 of the first support member 4a and the upper edges of the long hole sections 81, 82. Also, at this time, the lower spacer 15 surrounding the shaft section 700 of the lower shaft section 7 abuts against the upper edge of the central opening 90 of the lower guide groove 9 and the pair of guide surfaces 910, 920. As a result, the movement of the panel section 2 in a vertical position is restricted even when it is exposed to wind, making it easier to maintain the vertical position.

[0098] When an external force of a predetermined magnitude or greater is applied to the second display surface 21 of the panel unit 2 in the vertical position, as shown in Fig. 7B, the guide surface 920 of the second long hole portion 92 rides up onto the lower spacer 15 surrounding the shaft portion 700 of the lower shaft portion 7. Then, the shaft portion 600 of the upper shaft portion 6 approaches the outer edge of the second long hole portion 82, and the shaft portion 700 of the lower shaft portion 7 approaches the outer edge of the second long hole portion 92 of the lower guide groove 9. As a result, the panel unit 2 in the vertical position moves to an inclined position, and some of the external force acting on the panel unit 2 can be deflected.

[0099] Furthermore, when an external force of a predetermined magnitude or greater is applied to the first display surface 20 of the panel unit 2 in the vertical position, the guide surface 910 of the first long hole portion 91 rides up onto the lower spacer 15 surrounding the shaft portion 700 of the lower shaft portion 7. Then, the shaft portion 600 of the upper shaft portion 6 approaches the outer edge of the first long hole portion 81, and the shaft portion 700 of the lower shaft portion 7 approaches the outer edge of the first long hole portion 91 of the lower guide groove 9. As a result, the panel unit 2 in the vertical position moves to an inclined position, and some of the external force acting on the panel unit 2 can be deflected.

[0100] When the external force applied to the panel portion 2 is released, the weight of the panel portion 2 causes the upper shaft portion 6 to approach the central opening 80 of the upper guide groove 8, and the lower shaft portion 7 to approach the central opening 90 of the lower guide groove 9. This allows the panel portion 2 to automatically return to the vertical position shown in FIG. 7A.

[0101] 3-4. Variation 4 In the support mechanism 3 of the modified example 4 shown in Figures 8A and 8B, guide grooves 8, 9 are provided in each support portion 50 of the pair of second support members 5a, 5b of the second support portion 5, not in the first support portion 4. Fixing holes 400, 401 to which the shaft portions 6, 7 are fixed are provided in the supported portion 40 of the first support portion 4. The support mechanism 3 has two upper spacers 14 and two lower spacers 15 disposed in the guide grooves 8, 9 of the pair of second support members 5a, 5b. The fixing holes 400, 401 are screw holes.

[0102] The support mechanism 3 may not have the spacers 14, 15. In that case, the heads 601, 701 of the bolts 60, 70 of the shafts 6, 7 may be disposed in the guide grooves 8, 9 of one of the second support members 5a, and the fasteners having a circular outer shape attached to the shafts 600, 700 may be disposed in the guide grooves 8, 9 of the other of the second support members 5b.

[0103] The lower guide groove 9 is a long hole extending in the vertical direction. The upper guide groove 8 has a central opening 80 located directly above the lower guide groove 9, and a first long hole portion 81 and a second long hole portion 82 extending in opposite directions from the central opening 80. The first long hole portion 81 and the second long hole portion 82 are located lower in the vicinity of the central opening 80, and extend in an arc shape from the central opening 80 in a direction tilted upward relative to the horizontal direction. Each of the long hole portions 81 and 82 has a constant width in the short direction over the longitudinal direction. The support portion 50 of each of the pair of second support members 5a and 5b has guide surfaces 810 and 820 formed by the lower edges of the long hole portions 81 and 82.

[0104] In the support mechanism 3 of the fourth modification, as shown in Fig. 8A, when the panel portion 2 is in a vertical position, the upper spacer 14 surrounding the shaft portion 600 of the upper shaft portion 6 abuts against the lower edge of the central opening 80 of the upper guide groove 8 of each of the pair of second support members 5a, 5b and the guide surfaces 810, 820. Also, at this time, the lower spacer 15 surrounding the shaft portion 700 of the lower shaft portion 7 abuts against the lower edge and a pair of side edges of the lower guide groove 9 of each of the pair of second support members 5a, 5b. As a result, the movement of the panel portion 2 in a vertical position is restricted even when it is exposed to wind, making it easier to maintain the vertical position.

[0105] When an external force of a predetermined magnitude or more is applied to the second display surface 21 of the panel unit 2 in the vertical position, as shown in Fig. 8B, the upper spacer 14 surrounding the shaft portion 600 of the upper shaft portion 6 rides up onto the guide surface 820 of the second long hole portion 82. Then, the shaft portion 600 of the upper shaft portion 6 approaches the outer edge of the second long hole portion 82, and the shaft portion 700 of the lower shaft portion 7 approaches the upper edge of the lower guide groove 9. As a result, the panel unit 2 in the vertical position moves to an inclined position, and some of the external force acting on the panel unit 2 can be deflected.

[0106] Furthermore, when an external force of a predetermined magnitude or more is applied to the first display surface 20 of the panel unit 2 in the vertical position, the upper spacer 14 surrounding the shaft portion 600 of the upper shaft portion 6 rides up onto the guide surface 810 of the first long hole portion 81. Then, the shaft portion 600 of the upper shaft portion 6 approaches the outer edge of the first long hole portion 81, and the shaft portion 700 of the lower shaft portion 7 approaches the upper edge of the lower guide groove 9. This causes the panel unit 2 in the vertical position to move to an inclined position, allowing it to deflect part of the external force acting on the panel unit 2.

[0107] When the external force applied to the panel part 2 is released, the weight of the panel part 2 causes the upper shaft part 6 to approach the central opening part 80 of the upper guide groove 8, and the lower shaft part 7 to approach the lower edge of the lower guide groove 9. This allows the panel part 2 to automatically return to the vertical position shown in Fig. 8A.

[0108] 3-5. Variation 5 In the support mechanism 3 of the modified example 5 shown in Figs. 9A and 9B, guide grooves 8, 9 are provided in each of the support portions 50 of the pair of second support members 5a, 5b of the second support portion 5, instead of the first support portion 4. Fixing holes 400, 401 to which the shaft portions 6, 7 are fixed are provided in the supported portion 40 of the first support portion 4. The support mechanism 3 has two upper spacers 14 and two lower spacers 15 arranged in the guide grooves 8, 9 of the pair of second support members 5a, 5b. Note that the support mechanism 3 does not necessarily have to have the spacers 14, 15, as in the support mechanism 3 of the modified example 4.

[0109] The upper guide groove 8 is a long hole extending in the vertical direction. The lower guide groove 9 has a central opening 90 located directly below the upper guide groove 8, and a first long hole portion 91 and a second long hole portion 92 extending in opposite directions from the central opening 80. The first long hole portion 91 and the second long hole portion 92 are located lower in the vicinity of the central opening 90, and extend from the central opening 90 in an arc shape tilted upward with respect to the horizontal direction. Each of the long hole portions 91 and 92 has a constant width in the short direction over the longitudinal direction. The support portion 50 of each of the pair of second support members 5a and 5b has guide surfaces 910 and 920 formed by the lower edges of the long hole portions 91 and 92.

[0110] In the support mechanism 3 of the fifth modified example, as shown in Fig. 9A, when the panel section 2 is in a vertical position, the upper spacer 14 surrounding the shaft section 600 of the upper shaft section 6 abuts against the lower edge and a pair of side edges of the upper guide grooves 8 of each of the pair of second support members 5a, 5b. Also, at this time, the lower spacer 15 surrounding the shaft section 700 of the lower shaft section 7 abuts against the lower edge and guide surfaces 910, 920 of the central opening 90 of the lower guide groove 9 of each of the pair of second support members 5a, 5b. As a result, the movement of the panel section 2 in a vertical position is restricted even when it is exposed to wind, making it easier to maintain the vertical position.

[0111] When a predetermined or greater external force is applied to the second display surface 21 of the panel unit 2 in the vertical position, the lower spacer 15 surrounding the shaft portion 700 of the lower shaft portion 7 rides up onto the guide surface 910 of the first long hole portion 91 of each of the pair of second support members 5a, 5b, as shown in Fig. 9B. Then, the shaft portion 700 of the lower shaft portion 7 approaches the outer edge of the first long hole portion 91 of each of the pair of second support members 5a, 5b, and the shaft portion 600 of the upper shaft portion 6 approaches the upper edge of the upper guide groove 8 of each of the pair of second support members 5a, 5b. As a result, the panel unit 2 in the vertical position moves to an inclined position, and part of the external force acting on the panel unit 2 can be deflected.

[0112] Furthermore, when an external force of a predetermined magnitude or more is applied to the first display surface 20 of the panel unit 2 in the vertical position, the lower spacer 15 surrounding the shaft portion 700 of the lower shaft portion 7 rides up onto the guide surface 920 of the second long hole portion 92 of each of the pair of second support members 5a, 5b. Then, the shaft portion 700 of the lower shaft portion 7 approaches the outer edge of the second long hole portion 92 of each of the pair of second support members 5a, 5b, and the shaft portion 600 of the upper shaft portion 6 approaches the upper edge of the upper guide groove 8. As a result, the panel unit 2 in the vertical position moves to an inclined position, and part of the external force acting on the panel unit 2 can be deflected.

[0113] When the external force applied to the panel part 2 is released, the weight of the panel part 2 causes the upper shaft part 6 to approach the lower edge of the upper guide groove 8, and the lower shaft part 7 to approach the central opening 90 of the lower guide groove 9. This allows the panel part 2 to automatically return to the vertical position shown in Fig. 9A.

[0114] 4. Summary Like the display device 1 of the embodiment and its modified example described above, the display device (1) of the first aspect of the present disclosure has the following configuration.

[0115] That is, the display device (1) of the first embodiment includes a display panel unit (2) and a support mechanism (3) that supports the panel unit (2) so that the panel unit (2) can move between a vertical position parallel to the vertical direction and an inclined position inclined to the vertical direction. The support mechanism (3) has a first support unit (4) provided on the panel unit (2), a second support unit (5) provided on the ceiling (10) side, an upper shaft unit (6) connecting the first support unit (4) and the second support unit (5), and a lower shaft unit (7) connecting the first support unit (4) and the second support unit (5). The lower shaft unit (7) is located below the upper shaft unit (6). One of the first support unit (4) and the second support unit (5) is provided with an upper guide groove (8) into which the upper shaft unit (6) is inserted, and a lower guide groove (9) into which the lower shaft unit (7) is inserted. The upper guide groove (8) and the lower guide groove (9) are configured so that the upper shaft portion (6) moves along the upper guide groove (8) and the lower shaft portion (7) moves along the lower guide groove (9) to move the panel portion (2) between a vertical position and an inclined position.

[0116] According to the display device (1) of the first embodiment having the above configuration, when a passerby's baggage or the like collides with the panel portion (2), the upper shaft portion (6) moves along the upper guide groove (8) and the lower shaft portion (7) moves along the lower guide groove (9). This allows the panel portion (2) of the display device (1) of the first embodiment to move from a vertical position to an inclined position. Therefore, the display device (1) of the first embodiment can deflect the external force applied when colliding with a passerby's baggage or the like, and can suppress the occurrence of defects such as deformation of the support mechanism (3).

[0117] Furthermore, like the display device 1 of the embodiment and its modified example described above, the display device (1) of the second aspect of the present disclosure additionally has the following configuration in addition to the configuration of the display device (1) of the first aspect.
