FIG. 7 is a plan view showing a structure for attaching the third metal plate 7 of the first mounting bracket 4a. FIG. 8 is a partial perspective view showing a method of fixing the display module 100 to the guide rail 11.

  In order to facilitate the explanation of each drawing, the upward direction of the display device 200 is defined as the + Z axis direction, and the downward direction is defined as the −Z axis direction. Further, the left direction toward the display surface 3c is defined as + X axis direction, and the right direction is defined as -X axis direction. The direction from the display surface 3c to the back side of the display device 200 is the + Y axis direction, and the direction from the back side to the display surface 3c side is the -Y axis direction.

  The configuration of the display device 200 will be described with reference to FIG. The large display device 200 has a configuration in which a plurality of strip-shaped display modules 100, 101, 102 are arranged in the horizontal direction. The guide rails 11 and 12 are attached to the wall surface of the installation place where the large display device 200 is installed or a self-supporting stand steel frame so that the guide rails 11 and 12 are parallel to each other. The guide rails 11 and 12 are fixed to a wall surface or a self-supporting steel frame by screws (not shown) using fixing holes 1j formed at both ends of the guide rails 11 and 12.

  Next, the configuration of the display module 100 will be described with reference to FIG. The display module 100 includes a casing 2 made of a strip-shaped plate material, a display unit 3 that displays an image, and a mounting bracket 4. The casing 2 functions as a holding member for arranging a plurality of display units 3 in the Z-axis direction and holding them in a strip shape. The display unit 3 has a substantially square plate shape, and in FIG. 2, seven display units 3 are attached to the casing 2. The casing 2 is manufactured by extrusion molding of aluminum, and the surface in the −Y-axis direction of the casing 2 is processed into a flat shape so as to contact the heat generating portion 3 a of the display unit 3. The display unit 3 is screwed to the casing 2 using holes 3 b provided at the four corners of the display unit 3. An LED (Light Emitting Diode) element (not shown) is mounted on the display surface 3c of the display unit 3 over the entire surface.

  Mounting brackets 4a and 4b are screwed to the surface in the + Y-axis direction of the casing 2 to which the display unit 3 is attached at predetermined intervals. In FIG. 2, the second from the top is the first mounting bracket 4a, and the other three are the second mounting bracket 4b.

  When the display module 100 is attached to the guide rail 1, the attachment bracket 4 a is placed on the guide rail 11 from the upper side (+ Z-axis direction side) of the first guide rail 11. Thereby, the position of the display module 100 in the height direction (Z-axis direction) with respect to the guide rail 11 is determined. Further, when the mounting bracket 4b is in contact with the second guide rail 12 from the back side (−Y-axis direction side), the position of the display module 100 around the X-axis around the guide rail 11 is determined. The guide rail 11 is disposed on the upper side (+ Z axis direction side) with respect to the guide rail 12, and the guide rail 12 is disposed on the lower side (−Z axis direction side) with respect to the guide rail 11.

  Next, the configuration of the first mounting bracket 4a will be described with reference to FIG. The mounting bracket 4 a is composed of three sheet metal parts, a first sheet metal 5, a second sheet metal 6, and a third sheet metal 7. The sheet metal 5 has a U-shape, and an eccentric pin 92 is attached to a side surface in the −X axis direction, and a long hole in the Z axis direction into which the eccentric pin 92 is inserted on the side surface in the + X axis direction. 5a is provided. The eccentric pin 92 and the elongated hole 5a are for aligning the positions of the display surfaces 3c of the adjacent display modules 100 in the Y-axis direction. The display module 100 is moved on the guide rail 1 in the X-axis direction, and the adjacent display modules 100 are connected side by side. At this time, the eccentric pin 92 is inserted into the elongated hole 6c. The eccentric pin 92 is attached to the sheet metal 5 with a nut (not shown) through a member having a pressing force in the X-axis direction such as a spring washer. For this reason, the eccentric pin 92 can rotate around the axis, and the position in the Y-axis direction can be adjusted with respect to the adjacent display module 100. In FIG. 3, for ease of understanding, only a part of the sheet metal 5 of the metal fitting 4 a of the display module 100 adjacent in the −X axis direction is displayed, and the cut portion of the sheet metal 5 is hatched.

  The second sheet metal 6 is screwed to the sheet metal 5 from the + Y axis direction side. Screws (not shown) are inserted into screw fixing holes 6 a provided at both ends of the sheet metal 6 in the X-axis direction. The sheet metal 6 has an L shape in which a portion on the −Z axis direction side is bent in the + Y axis direction along a fold line parallel to the X axis. Two guide rollers 91 are attached to the bottom surface 6b formed in the −Z axis direction from the −Z axis direction. The guide roller 91 has a ball 91a rotatably attached to the support portion 91b from the −Z axis direction. Further, a screw portion 91c that is a male screw is formed in the + Z-axis direction of the support portion 91b. The screw portion 91 c of the guide roller 91 is attached to a screw hole 6 c provided in the bottom surface 6 b of the sheet metal 6. For this reason, if the support part 91b of the guide roller 91 is rotated around the Z axis, the position of the guide roller 91 in the Z axis direction with respect to the sheet metal 6 can be adjusted.

  A third sheet metal 7 is attached to the + Y axis direction side of the sheet metal 6. The sheet metal 7 has a W shape and is bent at approximately 90 degrees by three fold lines parallel to the X axis. The bottom surface 7c, which is one end surface, is fixed to the bottom surface 6b of the sheet metal 6 with screws in parallel to the XY plane. The back surface 7d which is the other end surface is parallel to the XZ plane, and three long holes 7b which are long in the Z-axis direction used when fixing the mounting bracket 4a to the guide rail 11 are equally spaced in the X-axis direction. It is provided side by side.

  FIG. 4 is a perspective view showing the configuration of the second mounting bracket 4b. The mounting bracket 4b has a configuration in which the guide roller 91 is removed from the first mounting bracket 4a, and the other configuration is the same as that of the mounting bracket 4a. Therefore, it is assembled using the same metal plates 5, 6, and 7 as the mounting bracket 4a. The same parts as those of the mounting bracket 4a are denoted by the same reference numerals, and description of the configuration is omitted.

  Next, the installation procedure of the display device 200 will be described with reference to FIGS. 1 and 5. The guide rails 11 and 12 are horizontally attached to a wall surface of a place where the display device 200 is installed or a self-supporting steel frame. For this reason, the guide rail 11 and the guide rail 12 are attached substantially in parallel. The guide rail 1 has a configuration in which a sheet metal 1a having a U-shaped cross section and a sheet metal 1b having a L-shaped cross section are joined by an adhesive or the like. The sheet metal 1a has a shape in which a bottom surface 1e is formed between two wall surfaces 1c and 1d. The sheet metal 1b has a shape in which a bottom surface 1g and a wall surface 1h are bent at approximately 90 degrees. These sheet metals 1a and 1b are joined to the bottom surface 1e of the sheet metal 1a and the bottom surface 1g of the sheet metal 1b. When the sheet metal 1a and the sheet metal 1b are joined, the wall surface 1c of the sheet metal 1a and the wall surface 1h of the sheet metal 1b are positioned so as to be on the same plane on the XZ plane. In the guide rail 1, a groove for guiding the guide roller 91 is formed by the wall surfaces 1c and 1d and the bottom surface 1e. This groove has an opening 1f.

  The guide rail 11 and the guide rail 12 use the same parts. The guide rail 11 attached to the + Z axis direction side is attached so that the opening 1f faces the + Z axis direction side. On the other hand, the guide rail 12 attached to the −Z-axis direction side is attached so that the opening 1 f faces the −Z-axis direction side.

  The guide roller 91 of the mounting bracket 4 a attached to the rear surface of the display module 100 on the + Y axis direction side is placed on the guide rail 11. At this time, the guide roller 91 is placed in the groove from the + Z-axis direction of the opening 1f and placed on the bottom surface 1e. In FIG. 1, the display module 101 is arranged at the end of the guide rail 1 in the −X axis direction, and the display module 102 is arranged side by side on the + X axis direction side of the display module 101. After the display module 100 is placed on the guide rail 1, the guide roller 91 moves on the bottom surface 1e of the guide rail 11 while being guided by the wall surfaces 1c and 1d. Are lined up. At this time, since the ball 91a of the guide roller 91 moves while rotating on the bottom surface 1e of the guide rail 11, the operator can easily move the display module 100 with a little force.

  For example, the display module 100 has a strip shape with a vertical length of 2 m, a horizontal length of 32 cm, and a weight of about 20 kg. Thus, by making the large display portion into the strip-shaped display module 100, the operator can lift the display module 100 alone and can perform the mounting work.

  FIG. 5 illustrates the operation of placing the display module 100 on the guide rail 1 in three states. FIG. 5 shows a partially enlarged view of mounting the mounting bracket 4 a on the guide rail 11 and a partially enlarged view of hitting the mounting bracket 4 b on the guide rail 12. The portions of the mounting bracket 4a and the guide rail 11 in FIG. 5A are enlarged in FIG. 5A1, and the portions of the mounting bracket 4b and the guide rail 12 are expanded in FIG. 5A2. The portions of the mounting bracket 4a and the guide rail 11 in FIG. 5B are enlarged in FIG. 5B1, and the portions of the mounting bracket 4b and the guide rail 12 are expanded in FIG. 5B2. The portion of the mounting bracket 4a and the guide rail 11 in FIG. 5C is enlarged in FIG. 5C1, and the portion of the mounting bracket 4b and the guide rail 12 is expanded in FIG. 5C2.

  FIG. 5A shows a state where the display module 100 is separated from the guide rails 11 and 12. FIG. 5B shows a state in which the guide roller 91 attached to the mounting bracket 4a is placed in the groove from the opening 1f of the guide rail 11 and placed on the bottom surface 1e. At this time, the mounting bracket 4b and the guide rail 12 are in a separated state. As shown by the arrow in FIG. 5B, the display module 100 is rotated counterclockwise around the X axis around the point where the ball 91a of the guide roller 91 contacts the bottom surface 1e of the guide rail 11. . FIG. 5C shows a state in which the mounting bracket 4b that has moved in FIG. 5B is positioned by hitting the wall surface 1h of the guide rail 12 from the -Y axis direction.

  The display module 100 can determine the position in the height direction (Z-axis direction) with respect to the guide rail 11 by placing the guide roller 91 on the guide rail 11. For this reason, the position of the plurality of display modules 100 in the height direction (Z-axis direction) can be easily adjusted by managing or adjusting the position of the guide roller 91 attached to the display module 100 in the Z-axis direction. Can do.

  Further, the cross section of the guide rail 11 has a groove shape formed by two wall surfaces 1c, 1d and a bottom surface 1e, and the guide roller 91 is placed in the groove. Therefore, even in the state of FIG. The display module 100 does not fall off from the guide rail 11. On the other hand, the guide rail 12 is attached by turning the guide rail 11 upside down. For this reason, when the display module 100 is rotated around the X axis, the mounting bracket 4b can be positioned against the wall surface 1h without contacting the wall surface 1d of the guide rail 12.

  As described above, the space in which the guide roller 91 can be placed on the guide rail 11 from the −Y axis direction and the + Z axis direction that are perpendicular to the X axis direction that is the length direction of the guide rails 11 and 12. That is, by having the opening, it is not necessary to insert the guide roller from the end of the guide rail as in the prior art. In this way, the display module 100 can be attached to the guide rail 1 in the vicinity of the adjacent display module 102 and the display modules 100 and 102 can be connected to each other, so that the operator can attach the display module 100 to the guide rail 1 in a short time. There is an advantage that it can be attached to.

  In addition to the guide rail 11 having the opening 1f on the + Z-axis direction side described in the first embodiment, for example, a part in the X-axis direction that is the longitudinal direction of the wall surface 1d of the guide rail 11 is notched. Even if the opening is provided, the guide roller 91 can be attached to the guide rail 11 from the −Y axis direction. However, in this case, as compared with the case where the display module 100 is attached to the guide rail 1 from an arbitrary position in the X-axis direction in the first embodiment, the display module 100 is only provided from the notches provided at regular intervals. Is attached to the guide rail 1. However, when the display module 100 is attached to the long guide rail 1, it is possible to attach the display module 100 from the notch portions provided at regular intervals, which has a certain effect. In addition, if there is a notch at the position where the display module 100 is fixed, the display module 100 may drop off from the guide rail 1, so it is necessary to remove the position of the notch from the position where the display module 100 is fixed. is there.

  As described above, the display module 100 attached to the guide rail 1 is moved by the operator to the end on the −X axis direction side of the guide rail 1, and then connected to the adjacent display module 102. The position in the height direction (Z-axis direction) with respect to the rail 11 is adjusted. Adjustment of the display module 100 in the height direction (Z-axis direction) is performed using a guide roller 91. The threaded portion 91c of the guide roller 91 is attached to a screw hole 6c provided in the bottom surface 6b of the sheet metal 6 of the mounting bracket 4a. For this reason, the position of the guide roller 91 in the Z-axis direction with respect to the sheet metal 6 can be easily adjusted by rotating the support portion 91b of the guide roller 91 about the axis. In FIG. 3, a groove is provided at the end in the + Z-axis direction of the screw portion 91c, and the guide roller 91 can be rotated by a minus driver. This work is performed from the back side (+ Y-axis direction side) of the display module 100.

  After adjusting the height of the display module 100 in this way, the eccentric pins 92 attached to the mounting brackets 4a and 4b of the display module 100 are inserted into the elongated holes 5a provided in the mounting brackets 4a and 4b of the adjacent display module 102. The two display modules 100 and 102 are connected by insertion.

  Next, the display surface 3c of the display unit 3 of the display module 100 and the display surface 3c of the surface display unit 3 of the adjacent display module 102 are adjusted to match the position in the Y-axis direction. The eccentric pin 92 has a structure in which a pin 92a is formed at one end in the axial direction of a support portion 92b having a hexagonal column shape, and a screw portion 92c is formed at the other end. The axis of the screw portion 92c and the axis of the support portion 92b are coincident with each other, but the axis of the pin 92a is offset from the axis of the screw portion 92c and the support portion 92b in the radial direction.

  For this reason, the position of the eccentric pin 9 in the Y-axis direction is changed by rotating the support portion 92b of the eccentric pin 92 around the X axis, which is the rotation direction of the axis of the eccentric pin 92, using a tool such as a spanner. be able to. Since the long hole 5a is a long hole in the Z-axis direction, the position of the display module 100 in the Y-axis direction changes with respect to the display module 102 due to the change in the position of the pin 92a in the Y-axis direction. On the other hand, the display modules 100 and 102 do not move in the Z-axis direction due to a change in the position of the pin 92a in the Z-axis direction. The threaded portion 92 of the eccentric pin 92 is attached to the sheet metal 5 with a nut sandwiching a part having a spring force such as a spring washer. For this reason, the eccentric pin 92 can be rotated or stopped around the X axis without causing a gap or the like between the eccentric pin 92 and the sheet metal 5 by loosening the fixing portion with the sheet metal 5.

  FIG. 6 is a view of the mounting bracket 4a as viewed from the side, and shows the positional relationship between the two adjacent metal plates 5 when the eccentric pin 92 is rotated. That is, FIG. 6 corresponds to a view of FIG. 3, which is drawn by partially cutting the sheet metal 5 of the adjacent mounting bracket 4 a as viewed from the −X axis direction. In order to easily understand the state of the eccentric pin 92, the state of the eccentric pin 92 in each state is separately shown on the upper side from FIG. 6 (a) to FIG. 6 (c). In consideration of the explanation using FIG. 1, the sheet metal 5 on the −X axis direction side (front side in FIG. 6) is the mounting bracket 4 a of the display module 102, and the + X axis direction side (back side in FIG. 6). The sheet metal 5 in () is the mounting bracket 4 a of the display module 100. Therefore, the movement by adjusting the eccentric pin 92 will be described as the mounting bracket 4a of the display module 100 on the back side.

  When the eccentric pin 92 is rotated 90 degrees counterclockwise from the state shown in FIG. 6B, the state shown in FIG. 6A is obtained. At this time, the sheet metal 5 on the + X-axis direction side (the back side in FIG. 6) moves in the + Y-axis direction by a dimension A corresponding to the eccentric amount of the eccentric pin 92. Looking at the holes 5b provided above and below the elongated hole 5a, it is on the + X axis direction side (the back side in FIG. 6) with respect to the hole 5b of the metal plate 5 on the −X axis direction side (the near side in FIG. 6). It can be seen that the hole 5b of the sheet metal 5 is on the + Y-axis direction side by the dimension A. In this case, the display module 100 on the + X axis direction side (the back side in FIG. 6) moves in the + Y axis direction with respect to the display module 102 on the −X axis direction side (the near side in FIG. 6).

  On the other hand, when the eccentric pin 92 is rotated 90 degrees clockwise from the state shown in FIG. 6B, the state shown in FIG. 6C is obtained. At this time, the sheet metal 5 on the + X-axis direction side (the back side in FIG. 6) moves in the −Y-axis direction by a dimension A corresponding to the eccentric amount of the eccentric pin 92. Looking at the holes 5b provided above and below the elongated hole 5a, it is on the + X axis direction side (the back side in FIG. 6) with respect to the hole 5b of the metal plate 5 on the −X axis direction side (the near side in FIG. 6). It can be seen that the hole 5b of the sheet metal 5 is on the −Y axis direction side by the dimension A. In this case, the display module 100 on the + X axis direction side (the back side in FIG. 6) moves in the −Y axis direction with respect to the display module 102 on the −X axis direction side (the near side in FIG. 6). .

  When the eccentric pin 92 is rotated, the elongated hole 5a has a long shape in the Z-axis direction. Therefore, the movement of the eccentric pin 92 in the Z-axis direction is absorbed by the elongated hole 5a, and the sheet metal 5 is moved in the Z-axis direction. Never move. Therefore, the position of the display module 100 in the Y-axis direction can be adjusted with a simple configuration. In addition, this work is performed from the back side (+ Y-axis direction side) of the display module 100.

  Next, the ring 93b of the connection fitting 93 attached to the −X-axis direction side of the attachment fittings 4a and 4b of the display module 100 is attached to the + X-axis direction side of the attachment fittings 4a and 4b of the adjacent display module 102. After being hooked on the hook 94, the display module 100 and the display module 102 are connected by tilting the lever 93a to the + X axis direction side.

  The third sheet metal 7 is fixed to the bottom surface 6b of the second sheet metal 6 with screws through a member having a pressing force in the Z-axis direction, such as a spring washer. As shown in FIG. 7, a long hole 7 a that is long in the Y-axis direction is provided in the bottom surface 7 c of the third metal plate 7, and the metal plate 7 can move in the Y-axis direction with respect to the metal plate 6. Further, as described above, the sheet metal 7 is screwed to the sheet metal 6 with the spring washer interposed therebetween. Therefore, when the position of the sheet metal 7 is moved relative to the sheet metal 6 by slightly loosening the screw, the sheet metal 7 is also moved. Can be moved without tilting. As will be described next, the sheet metal 7 is fixed to the guide rails 11 and 12, but at this time, the screws are slightly loosened so that the sheet metal 7 can move in the Y-axis direction with respect to the sheet metal 6. FIG. 7 shows a part of the sheet metal 6 cut so that the bottom surface 7c portion can be seen. The cut portion is hatched.

  Next, the third metal plate 7 is fixed to the guide rails 11 and 12. As shown in FIGS. 3 and 4, three long holes 7 b that are long in the Z-axis direction are provided on the back surface 7 d of the sheet metal 7. A screw hole 1i in which a female screw is formed is provided at a position corresponding to the long hole 7b of the guide rails 11 and 12. The operator inserts the screw into the elongated hole 7b from the −Y axis direction of the back surface 7d and fixes it to the screw hole 1i of the guide rails 11 and 12. As a result, the mounting brackets 4 a and 4 b are fixed to the guide rails 11 and 12.

  At this time, the metal plates 5 and 6 are connected to the mounting brackets 4a and 4b of the adjacent display modules by the eccentric pins 92, and the metal plates 5 and 6 cannot move in the Y-axis direction. Therefore, even when there is a gap between the back surface 7 d of the sheet metal 7 and the guide rails 11, 12, the sheet metal 7 is Y-axis relative to the sheet metal 6 when the sheet metal 7 and the guide rails 11, 12 are screwed. The sheet metal 7 can be fixed to the guide rails 11 and 12 by screws. After fixing the sheet metal 7 to the guide rails 11 and 12, the work of attaching the display module 100 to the guide rail 1 is completed by tightening the screws that connect the sheet metal 6 and the sheet metal 7. Thereafter, the display module 100 is sequentially connected in the horizontal direction in the same procedure, whereby the large display device 200 is installed. Although the number of the long holes 7b of the sheet metal 7 is three, it can be arbitrarily determined depending on the size of the sheet metal 7, and is not limited to this number.

  As shown in FIG. 1, in the first embodiment, one mounting bracket 4b is disposed above and below the mounting brackets 4a and 4b described above. Although these two mounting brackets 4b do not contact the guide rail 1, the position of the display surface 3c in the Y-axis direction can be adjusted by rotating the eccentric pin 92. Thereby, the shift | offset | difference of the Y-axis direction of the display surface 3c by the curvature of the display module 100 can be corrected.

  Further, the rotating portion of the guide roller 91 is not limited to the cylindrical shape, and a spherical ball 91a is used. However, a generally used cylindrical shape that is rotated and used can also be used. FIG. 9 shows a cylindrical roller. 9A is a perspective view of the guide roller 91 using the roller 91e, and FIG. 9B has a groove (recess) on the cylindrical surface of the roller 91f, and the guide rail 13 has a protrusion corresponding to the groove. FIG. 9C is an explanatory diagram of the roller 91f and the guide rail 13 having a portion, and FIG. 9C has a convex portion on the cylindrical surface of the roller 91g, and the guide rail 14 has a groove (concave portion) corresponding to the convex portion. It is explanatory drawing of 91g and the guide rail 14. FIG. The guide rails 13 and 14 are cross-sectional views cut along a plane perpendicular to the longitudinal direction of the guide rails 13 and 14, and the cross sections are hatched.

  The roller 91e shown in FIG. 9A is placed on the bottom surface 1e of the groove of the guide rail 11, and is guided by the groove of the guide rail 11 to move. When the roller 91e is fixed around the axis with respect to the support portion 91d, the guide roller 91 can be adjusted only in 180-degree units in height in the Z-axis direction, resulting in coarse adjustment accuracy. This is different from the guide roller 91 using the ball 91a. In this respect, the guide roller 91 using the ball 91a has an advantage that the height in the Z-axis direction can be finely adjusted with a simple configuration. In the case where the roller 91e has a structure that can rotate about the axis with respect to the support portion 91d, the height in the Z-axis direction can be finely adjusted.

  The roller 91f shown in FIG. 9B has a structure having grooves (concave portions) in the circumferential direction on the cylindrical surface of the roller 91f. Unlike the guide rail 11, the guide rail 13 has a convex portion corresponding to the concave portion of the roller 91f in the longitudinal direction of the guide rail 13. Since the concave portion of the roller 91 f is fitted into the convex portion of the guide rail 13, the roller 91 f can be guided and moved in the longitudinal direction of the guide rail 13.

  The roller 91g in FIG. 9C has a structure having a convex portion in the circumferential direction on the cylindrical surface of the roller 91g. Unlike the guide rail 11, the guide rail 14 has a concave portion (groove portion) corresponding to the convex portion of the roller 91g in the longitudinal direction of the guide rail 14. Since the convex part of the roller 91g is fitted into the concave part of the guide rail 14, the roller 91g can be guided and moved in the longitudinal direction of the guide rail 14.

  The guide roller 91 using the rollers 91e, 91f, 91g described in FIG. 9 is the same as the guide roller 91 using the ball 91a, except for the adjustment accuracy of the height adjustment of the guide roller 91 in the Z-axis direction. An effect can be obtained.

  As described above, the adjustment of the height (Z-axis direction) of the display module 100 using the guide roller 91 and the position adjustment of the display surface 3 c of the adjacent display module 100 using the eccentric pin 92 are performed by the display module 100. This can be done from the back (+ Y-axis direction) side. The ability to perform the adjustment work from the back side of the display module 100 is effective when a signboard viewed from the platform of a station with a rail interposed therebetween or a signboard along a road with a lot of traffic is replaced with the display device of the present invention.

  Since the display surface of the signboard that sandwiches the rail from the station platform is close to the rail, the operator cannot work on the display surface side using a long time during the time when the train is operating. For this reason, in the display device 200 according to the first embodiment, the display module 100 can be attached to the guide rail 1 in the vicinity of the position where the display module 100 is attached among the long guide rails 1. Work time can be shortened. Thereafter, the adjustment work for adjusting the positional relationship between the adjacent display modules 100 can be performed from the back side (+ Y-axis direction) side of the display device, so that the work can be performed safely even if a certain amount of time is required.

  In this way, in addition to attaching the display module 100 to the guide rail 1 in a short time from the display surface side of the display device 200, an adjustment operation that requires a certain amount of time can be performed from the back side of the display device 200, thereby Even when the display device 200 is used for a signboard that sandwiches the rails or a signboard along a road with a large amount of traffic, there is an advantage that the worker can perform the installation work safely.

Embodiment 2. FIG.
In the first embodiment, the position adjustment of the adjacent display module 110 in the Y-axis direction is performed by the eccentric pin 92. In the second embodiment, the display surfaces 3c of the adjacent display units 3 are aligned using the concave portions 21a and the convex portions 21b provided on the side surface of the casing 21 in the X-axis direction. In addition, about the component similar to Embodiment 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  FIG. 10 is a perspective view showing a positioning structure of adjacent display modules 110 and 112 in the Y-axis direction. For ease of explanation, the upper and lower parts are cut out. Since the casing 21 of the display modules 110 and 112 shown in FIG. 10 is manufactured by extrusion processing, it is excellent in manufacturing a long one having a constant cross-sectional shape. A heat sink 21c extending in the Z-axis direction is formed on the + Y-axis direction side (back side) of the casing 21. A mounting bracket 4a is attached to the + Y-axis direction side of the heat sink 21c. On the end surface of the casing 21 on the + X-axis direction side, a concave portion 21a having a concave cross section by the XY plane is formed. On the end surface on the −X axis direction side of the casing 21, a convex portion 21 b having a convex section in the XY plane is formed.

  When the display module 110 is connected to the display module 112, the convex portion 21b of the display module 110 is fitted into the concave portion 21a of the display module 112, thereby aligning the positions of the display surfaces 3c of the adjacent display modules 110 and 112 in the Y-axis direction. be able to. Further, since the concave portion 21a and the convex portion 21b are formed in almost the entire range in the Z-axis direction, the warpage in the Z-axis direction of the display modules 110 and 112 can be corrected.

Embodiment 3 FIG.
In the first and second embodiments, the casings 2 and 21 for fixing the display unit 3 are parts manufactured by extruding aluminum. In the third embodiment, the casings 2 and 21 are manufactured by drawing a sheet metal. . The configuration of the adjacent display modules 120 will be described using FIG. 11, and the positioning structure between the adjacent display modules 120 and 122 will be described using FIG.

  FIG. 11 is an exploded perspective view showing the configuration of display module 120 according to Embodiment 3 of the present invention. FIG. 12 is a partially enlarged view in which the periphery of the connecting portion 22a formed in the casing 22 for connecting the adjacent display modules 120 and 122 is enlarged. In addition, about the component similar to Embodiment 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  As shown in FIG. 11, the display module 120 has seven display units 3. Each display unit 3 includes two heat sinks 95 in the heat generating unit 3a. The heat sink 95 is fixed to the heat generating portion 3a with a silicon adhesive having good thermal conductivity. The display unit 31 in which the display unit 3 and the heat sink 95 are integrated is screwed to the casing 22 using mounting holes 3 b provided at four corners of the display unit 3. The casing 22 is formed into a box shape by drawing a sheet metal or the like. Further, a rectangular hole 22d is formed in the corresponding portion so that the heat sink 95 of the display unit 31 is exposed from the back surface on the + Y-axis direction side. The display unit 31 is attached to a portion corresponding to the bottom surface of the box-shaped outer side of the casing 22. That is, the box-shaped side surface is a shape standing in the + Y-axis direction. After the display unit 31 is attached to the casing 22, the cover 23 is attached from the + Y-axis direction side.

  The cover 23 is provided with a rectangular hole 23 b for exposing the heat sink 95, similar to the casing 22. Mounting brackets 4a and 4b are attached from the + Y-axis direction between the adjacent holes 23b and the Z-axis direction of the holes 23b. The cover 23 is provided with six screw holes 23a for attaching the mounting brackets 4a and 4b. Screw holes are provided at corresponding positions on the sheet metal 5 of the mounting brackets 4a and 4b. Screws are inserted into the holes of the sheet metal 5 from the + Y-axis direction and screwed.

  Next, a positioning method in the Y-axis direction and the Z-axis direction between the adjacent display modules 120 and 122 will be described with reference to FIG. Connecting portions 22a for positioning adjacent display modules 120 and 122 are formed on both side surfaces on the X-axis direction side produced by drawing the sheet metal of the casing 22. Three holes 22b and 22c are formed in the connecting portion 22a side by side in the Z-axis direction. Of the three holes, the middle hole is the hole 22b, and the two holes at both ends are the holes 22c.

  In the display module 120 configured as described above, the positioning component 24 is used to align the positions of the adjacent display modules 120 and 122 in the Y-axis direction and the Z-axis direction. The positioning component 24 has a pin 24b protruding from the front side and the back side at the center of the plate portion 24a. Two screwing holes 24c are provided in the Z-axis direction across the pin 24b.

  When connecting the adjacent display modules 120 and 122, the pins 24 b of the positioning component 24 are inserted into the holes 22 b provided in the connecting portions 22 a of the display modules 120 and 122. Thereby, the positions of the display modules 120 and 122 in the Y-axis direction and the Z-axis direction can be matched. The aligned display modules 120 and 122 are fixed to the holes 22c of the connecting portion 22a through screws with the positioning component 24 sandwiched between the connecting portions 22a of the display modules 120 and 122. Thereby, the position between the adjacent display modules 120 and 122 can be determined with a simple configuration. Further, in the configuration of the display module 120, since the thin sheet metal casing 22 is used, the display module 120 can be made thinner than the first and second embodiments. Further, since the mounting brackets 4a and 4b are attached to a place where the heat sink 95 is not provided in the second embodiment, the thin display module 120 can be obtained.

Embodiment 4 FIG.
In the first embodiment, the connection fitting 93 and the hook 94 are used as means for connecting the adjacent display modules 100. In the fourth embodiment, a configuration in which the screws are used for connection is shown. FIG. 13 is a perspective view showing the configuration of the third mounting bracket 4c. The same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  In Embodiment 3, after positioning the adjacent display modules 120 and 122 using the positioning component 24, the adjacent display modules 120 and 122 are fixed using screws. The mounting bracket 4c according to the fourth embodiment is configured to fix adjacent display modules with screws.

  As for the attachment component 4c, the 4th sheet metal 8 is attached to the both end surfaces of the sheet metal 6 of the X-axis direction. The sheet metal 8 has a shape bent into an L shape of approximately 90 degrees along a fold line parallel to the Y axis. The bottom surface 8b is fixed to the bottom surface 6b of the sheet metal 6 with screws so that the side surface 8a of the sheet metal 8 is parallel to the YZ plane. The side surface 8a is provided with a hole 8c for inserting a screw and a screw hole 8d which is a female screw side by side in the Z-axis direction. The hole 8c is provided at a position corresponding to the screw hole 8d of the adjacent mounting bracket 4c. For this reason, the hole 8c and the screw hole 8d between the sheet metal 8 on the −X axis direction side and the sheet metal 8 on the + X axis direction side are provided at positions that are upside down in the Z axis direction (vertical direction). Then, one screw is inserted from each of the holes 8c of the adjacent mounting bracket 4c and is screwed by the screw holes 8d. That is, the two screws are each attached in the opposite direction in the X-axis direction.

  By using this mounting bracket 4c, adjacent display modules 100 can be easily connected.

Embodiment 5 FIG.
In the first embodiment, two guide rollers 91 are attached to the first mounting bracket 4a. In the first embodiment, the positioning pin is not provided on the side surface of the upper end portion or the lower end portion of the casing 2. However, in the fifth embodiment, one guide roller 91 is disposed substantially at the center of the mounting bracket 4d. Moreover, the positioning pin 25a was provided in the side surface of the upper end part of the casing 2 of a display module, or the side surface of a lower end part. In addition, the same code | symbol is attached | subjected to the component same as Embodiment 1, and the description is abbreviate | omitted.

  FIG. 14 is a perspective view showing the configuration of the fourth mounting bracket 4d according to Embodiment 5 of the present invention. Here, it demonstrates in contrast with the 1st attachment metal fitting 4a shown in FIG. 3 of Embodiment 1. FIG. Two guide rollers 91 are mounted on the bottom surface 6b of the second metal plate 6 of the first mounting bracket 4a. However, one guide roller 91 is attached to the fourth mounting bracket 4d at substantially the center of the bottom surface 6b of the second sheet metal 6. Further, standing walls 6d bent in an L shape are formed at both ends in the X-axis direction of the second sheet metal 6 of the fourth mounting bracket 4d. The standing wall 6d is composed of two surfaces. One surface is a surface parallel to the YZ plane obtained by bending the bottom surface 6b approximately 90 degrees in the Z-axis direction. The other surface is a surface parallel to the ZX plane obtained by bending a surface parallel to the YZ plane approximately 90 degrees inward in the X-axis direction.

  The fourth mounting bracket 4d is placed on the guide rail 1 with one guide roller 91 in contact with the guide rail 1. For this reason, the fourth mounting bracket 4d can be tilted about the Y axis with the guide roller 91 as a fulcrum. That is, the fourth mounting bracket 4d becomes very unstable when placed on the guide rail 1. For this reason, the standing wall 6d eliminates the instability of the fourth mounting bracket 4d. That is, when the fourth mounting bracket 4d rotates about the Y axis, the standing wall 6d contacts the guide rail. This restriction prevents the fourth mounting bracket 4d from falling.

  Next, with reference to FIGS. 15 and 16, the positioning structure, the fastening structure, and the mounting procedure of the adjacent display modules 130 and 132 will be described. The display modules 130 and 132 are in a state of being placed on the guide rail 1. 15 and 16 are rear views of the display modules 130 and 132 placed on the guide rail 1. FIG. 15 shows a first state of the attachment procedure, and FIG. 16 shows a second state of the attachment procedure. 15 and 16 are partial detailed views in which the lower half of the display modules 130 and 132 are omitted in order to show the vicinity of the mounting bracket 4d in detail. The detailed shape of the guide rail 1 is also omitted. The lower surface 1e that receives the guide roller 91 is indicated by a solid line.

  The first display module 130 shown in FIG. 15 has been installed. The installation operator moves the second display module 132 on the guide rail 1 and carries it next to the first display module 130. At this time, in FIG. 15, the second display module 132 is tilted counterclockwise around the Y axis with the guide roller 91 as the center. At this time, the standing wall 6 d of the second display module 132 on the first display module 130 side is in contact with the guide rail 1. The second display module 132 is adjusted to a substantially equal height with respect to the first display module 130 by adjusting the height of the guide roller 91.

  As shown in FIG. 15, positioning pins 25 a are provided at the upper end of the side surface of the casing 2 in the −X-axis direction. A long slot extending in the Z-axis direction is provided on the side surface in the + X-axis direction of the casing 2 at a position corresponding to the positioning pin 25a. The positioning pin 25 a is a pin that is slightly longer than the eccentric pin 92.

  In the state of FIG. 15, the second display module 132 is tilted counterclockwise. When the second display module 132 is brought close to the first display module 130 in this state, the positioning pin 25a at the upper end portion of the second display module 132 is aligned with the elongated hole at the upper end portion of the first display module 130 and first. Inserted into. This is because the positioning pin 25 is longer than the eccentric pin 92 in addition to the second display module 132 being inclined counterclockwise.

  Further, it is necessary to rotate the eccentric pin 92 to align the positions of the adjacent display surfaces 3c. That is, the positioning pin 25a inserted into the elongated hole at the upper end of the first display module 130 needs to move in the Y axis direction within the adjustment range of the eccentric pin 92 in the Y axis direction. For this reason, the dimension of the long hole in the Y-axis direction is large with a margin with respect to the diameter of the positioning pin 25a.

  The position of the second display module 132 in the Y-axis direction is regulated by the positioning pin 25a. Thereafter, the second display module 132 is rotated clockwise, and the eccentric pin 92 of the second display module 132 is inserted into the long hole 5a of the module 130 of the first display. Insertion of the eccentric pin 92 into the elongated hole 5a is sequentially performed from the + Z axis direction.

  The first sheet metal 5 of the fourth mounting bracket 4d has the same shape as the first sheet metal 5 of the first mounting bracket 4a shown in the first embodiment. Therefore, the fourth mounting bracket 4d of the first display module 130 has a long hole 5a. Even in the state where the second display module 132 is inclined as in the first state shown in FIG. 15, the elongated hole 5a is a long hole in the Z-axis direction, so that the eccentric pin 92 of the second display module 132 is attached to the first display module 132. It can be inserted into the elongated hole 5a of the display module 130.

  The second display module 132 can rotate around the Y axis. After the position in the Y-axis direction is regulated by the positioning pin 25a, the eccentric pins 92 are inserted into the elongated holes 5a in order from the + Z-axis direction. First, since the position of the second display module 132 in the Y-axis direction is regulated by the positioning pin 25a, the subsequent insertion of the eccentric pin 92 into the elongated hole 5a becomes easy. For this reason, the display module according to Embodiment 5 eliminates the troublesome work of aligning and inserting the plurality of eccentric pins 92 at a time. In addition, a large number of positioning pins can be easily inserted, and the assembly is excellent. By providing the positioning pin 25a at the lower end portion of the casing 2, the same effect can be obtained even when the second display module 132 is tilted clockwise around the Y axis.

  In the fifth embodiment, the positioning pin 25 a is provided on the upper end portion of the casing 2. However, the mounting bracket 4b can be arranged at the upper end portion so that the eccentric pin 92 has the function of the positioning pin 25a. At this time, only the eccentric pin 92 at the upper end can be made slightly longer than the other eccentric pins 92.

  In the state where the eccentric pin 92 of the second display module 132 is inserted into the elongated hole 5a of the first display module 130, the first mounting module 4b of the second display module 132 is adjacent to the first mounting module 4b using the connecting metal 93. The display module 130 is connected to the mounting bracket 4b. At this time, the second display module 132 can rotate around the Y axis with the guide roller 91 as a fulcrum. For this reason, the installation operator can rotate the display module 132 clockwise with the Y axis as a center with a light force. In the mounting bracket 4b, the eccentric pin 92 of the second display module 132 is inserted into the elongated hole 5a of the first display module. Since the long hole 5a is long in the Z direction, the eccentric pin 92 is movable in the Z direction. Therefore, the posture of the second display module 132 can be easily corrected.

  Further, the second display module 132 can be arranged along the first display module 130. For this reason, the eccentric pin 92 of the mounting bracket 4d of the second display module 132 disposed on the lower side of the mounting bracket 4b can be inserted into the elongated hole 5a of the mounting bracket 4d of the first display module 130. The display modules 130 and 132 are arranged to be rotatable around the Y axis. For this reason, a large force is not required to fix the adjacent display modules 130 and 132. That is, the first display module 130 and the second display module 132 can be assembled without a gap even when the connection fitting 93 having a relatively weak fastening force is used. Thereafter, by sequentially connecting the display modules 130 in the same procedure, all the display modules 130 can be assembled without gaps. By disposing one guide roller 91 at the center of the display module 130 as in the fifth embodiment, the display module 130 can rotate around the Y axis. For this reason, the display module 130 can be more easily connected without a gap.

Embodiment 6 FIG.
In the fifth embodiment, one guide roller 91 is arranged near the center of the mounting bracket 4d. Thereby, the display module 130 was able to rotate around the Y axis. In the sixth embodiment, the fifth mounting bracket 4e is provided with a height adjustment mechanism and a rotation mechanism around the Y axis. Thus, the height of the display module 130 can be adjusted while the display module 130 has a degree of freedom of rotation about the Y axis. In addition, the same code | symbol is attached | subjected to the component same as Embodiment 5, and the description is abbreviate | omitted. The mounting bracket 4 e has a function as a mounting portion that is mounted to the casing 2.

  FIG. 17 is an exploded perspective view showing a structure of a fifth mounting bracket 4e having an adjustment mechanism in the height direction of the display module 130 and a rotation mechanism around the Y axis. As shown in FIG. 17, the base sheet metal 9 is fixed to the bottom surface 6 b of the second sheet metal 6. The base metal plate 9 has two screw holes 9a. The base sheet metal 9 is fixed to the sheet metal 6 using the screw holes 9a. As the screw, a screw whose head is further shaped is used. A base metal plate 9 is fixed to the metal plate 6 by inserting a screw through a hole provided in the bottom surface 6b (not shown) from the + Z-axis direction and fitting the screw into the screw hole 9a. Since the head of the screw has a further shape, even if the sheet metal 7 is attached to the bottom surface 6b from the + Z-axis direction, the sheet metal 7 does not float with respect to the bottom surface 6b. The cross-sectional shape of the base metal plate 9 on the YZ plane is a substantially U-shape having an opening in the direction facing the guide rail 1 (−Z direction). The surface 9b of the base metal plate 9 is a plane substantially parallel to the ZX plane. The surface 9b extends in the −Z-axis direction from both end surfaces of the bottom surface 9e in the Y-axis direction. Each of the surfaces 9b has a long hole 9c that is long in the Z-axis direction.

  The chassis sheet metal 10 is disposed inside the U-shape of the base sheet metal 9. The chassis sheet metal 10 is attached to the base sheet metal 9 by a shaft 17 described later. The chassis sheet metal 10 can rotate around the Y axis about the shaft 17 with respect to the base sheet metal 9. The cross-sectional shape of the chassis sheet metal 10 in the YZ plane is a substantially U-shape having an opening in the direction facing the guide rail 1 (−Z direction). The surface 10b of the chassis sheet metal 10 is a plane substantially parallel to the ZX plane. The surface 10b extends in the −Z-axis direction from both end surfaces of the bottom surface 10e in the Y-axis direction. Each of the surfaces 10b has a hole 10c. The shaft 17 passes through the hole 10c. Both ends of the bottom surface 10e in the X-axis direction have protrusions protruding in the X-axis direction. Each of the protrusions is provided with a screw hole 10a. The guide roller 91 is attached to the screw hole 10 a by a screw portion 91 c provided on the guide roller 91. The chassis metal plate 10 has a function as a holding portion that holds the guide roller 91.

  The rotating base sheet metal 15 is disposed inside the U-shape of the chassis sheet metal 10. The cross-sectional shape of the rotary base sheet metal 15 in the YZ plane is a substantially U-shape having an opening in the + Z direction. The rotating base sheet metal 15 is similarly attached to the chassis sheet metal 10 by the shaft 17. The rotating base sheet metal 15 can rotate around the Y axis about the shaft 17 with respect to the base sheet metal 9 and the chassis sheet metal 10.

  The surface 15a of the rotating base sheet metal 15 is a plane substantially parallel to the ZX plane. The surface 15a extends in the + Z-axis direction from both end surfaces of the bottom surface 15c in the Y-axis direction. The opposing surface 15a of the rotating base metal plate 15 is provided with a hole 15b through which the shaft 17 is inserted. The bottom surface 15c has two screw holes 15d. A pedestal 16 to be described later is screwed to the rotating base metal plate 15 using two holes 16a and two screw holes 15d. The mounting screw is inserted into the hole 16a from the + Z-axis direction and then fitted into the screw hole 15d. The pedestal 16 has a convex shape in the + Z direction. The adjusting screw 18 is attached to the second sheet metal 6. The screw portion 18 a of the adjustment screw 18 is fitted into the screw hole 6 e of the second sheet metal 6.

  The screw portion 18 a of the adjustment screw 18 passes through the hole 9 d of the base sheet metal 9 and the hole 10 d of the chassis sheet metal 10. The screw portion 18 a does not contact the base sheet metal 9 and the chassis sheet metal 10. The tip end portion 18 b of the adjustment screw 18 contacts the top portion 16 b of the pedestal 16. The shaft 17 passes through the base sheet metal 9, the chassis sheet metal 10, and the rotating base sheet metal 15. The shaft 17 is attached so as not to come off in the Y-axis direction by a retaining part such as an e-ring (not shown).

  A method of adjusting the height of the display module using the fifth mounting bracket 4e according to Embodiment 6 will be described. FIG. 18 is a rear view of the fifth mounting bracket 4e at the reference position. FIG. 19 is a rear view of the fifth mounting bracket 4e after the display module is lifted in the + Z direction. The fifth mounting bracket 4e shown in FIG. 19 is moved in the + Z-axis direction with respect to the chassis metal plate 10 from the fifth mounting bracket 4e shown in FIG. 18 and 19, the hidden line is indicated by a broken line.

  The adjusting screw 18 is coupled to the second sheet metal 6 by screwing. The tip 18b of the adjusting screw 18 is in contact with the top 16b of the pedestal. Accordingly, when the adjustment screw 18 is rotated in the direction in which the screw is tightened, the adjustment screw 18 moves in the −Z direction with respect to the fifth mounting bracket 4e. Then, the adjusting screw 18 moves the base 16 in the −Z axis direction.

  The pedestal 16 is screwed to the rotating base sheet metal 15. Further, the rotating base sheet metal 15 and the chassis sheet metal 10 are integrated by the shaft 17 passing therethrough. As a result, the rotary base metal plate 15, the pedestal 16, and the shaft 17 move together in a direction away from the second metal plate 6.

  The through hole of the shaft 17 of the base metal plate 9 is a long hole 9c that is long in the Z-axis direction. For this reason, the rotation base sheet metal 15 and the chassis sheet metal 10 integrated by the shaft 17 can move in the Z-axis direction along the long hole 9c. That is, the position of the rotating base sheet metal 15 and the chassis sheet metal 10 can be changed in the Z-axis direction with respect to the base sheet metal 9. The base metal plate 9 is fixed to the fifth mounting bracket 4e. The fifth mounting bracket 4e is attached to the display module. For this reason, the height of the display module with respect to the guide rail 1 can be adjusted.

  Next, a rotation mechanism around the Y axis of the display module will be described with reference to FIG. FIG. 20 is a rear view of the fifth mounting bracket 4e after the display module is rotated around the Y axis. A shaft 17 passes through the rotary base sheet metal 15 and the chassis sheet metal 10. For this reason, the rotating base sheet metal 15 can rotate around the Y axis around the shaft 17 with respect to the chassis sheet metal 10.

  On the other hand, the chassis sheet metal 10 is placed on the guide rail 1 by two guide rollers 91. Further, the second sheet metal 6 is fixed to the display module via the first sheet metal 5. Accordingly, the display module can rotate about the Y axis with respect to the guide rail 1. Further, the rotating base sheet metal 15 and the pedestal 16 can rotate around the Y axis about the shaft 17 with respect to the chassis sheet metal 10. For this reason, when the chassis sheet metal 10 is tilted, the rotating base sheet metal 15 and the base 16 are not tilted. For this reason, the front-end | tip part 18b of the adjustment screw 18 can contact the top part 16b of the base 16 stably. As described above, the mechanism according to the sixth embodiment has an advantage that the inclination and height of the display module can be adjusted when the guide rail 1 is attached to be inclined with respect to the installation location.

  Moreover, the shaft 17 is attached to the approximate center of the display module in the X-axis direction. For this reason, even if the guide rail 1 is not installed horizontally with respect to the installation location, the display module itself balances around the shaft 17 and keeps the posture horizontal. For this reason, there is an advantage that it is not necessary to adjust the guide rail 1 horizontally with high accuracy. Furthermore, since the display module itself takes a horizontal orientation, it can be connected to the adjacent display module by a simple operation when combining adjacent display modules, and the installation time can be reduced.

  Further, when the installation operator inserts the positioning pin 25a of the display module into the elongated hole at the upper end of the display module, it is not necessary to turn the screw portion 91c of the guide roller 91 to adjust the height of the display module. This is because the positioning pin 25a is inserted into the long hole in the Z-axis direction, so that the display module can be inserted without fine adjustment in the height direction (Z-axis direction). For this reason, it can be fitted to adjacent display modules by a simple operation, and the installation time can be greatly reduced.

  In each of the embodiments described above, the display device is configured by spreading LEDs on a flat surface. However, a display module is configured using a panel such as a liquid crystal display, a plasma display, and an organic EL display. You can also. In addition, expressions with “substantially” such as approximately square, approximately 90 degrees, and approximately parallel are used, and this indicates that a range that takes into account manufacturing tolerances, assembly variations, and the like is included. For this reason, even if “abbreviation” is not described in the claims, it includes a range that takes into account manufacturing tolerances and assembly variations.
