DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIG. 1, a video display 10 in accordance with the present embodiment is a wall-mounting display conforming to the VESA standard, and has a monitor body 12. On the front surface of the monitor body 12, a screen SC for displaying a video is furnished. The back of the monitor body 12 is covered with a polystyrene back cabinet 14.
Referring to FIG. 2 and FIG. 3, at the center and slightly above a main surface of the back cabinet 14, two embossing portions 141 and 142 extending linearly in the vertical direction are integrally formed. Both of the embossing portions 141 and 142 are formed such that the convex portions appear on a rear surface of the back cabinet 14. By arranging the embossing portions 141 and 142 in the horizontal direction, it is possible to improve a bending strength in the vertical direction of the back cabinet 14. Furthermore, the convex portions appear on the rear surface, so that wall-mounting is not hindered by the embossing portions 141 and 142.
In the vicinity of the embossing portion 141, protrude cylindrical portions 143a and 143b are integrally formed on the rear surface of the back cabinet 14. Similarly, in the vicinity of the embossing portion 142, protrude cylindrical portions 143c and 143d are integrally formed on the rear surface of the back cabinet 14. The cylindrical portions 143a and 143b are provided outside the embossing portion 141 along the longitudinal direction of the embossing portion 141. Similarly, the cylindrical portions 143c and 143d are provided outside the embossing portion 142 along the longitudinal direction of the embossing portion 142.
The cylindrical portions 143a-143d respectively have through holes H1a-H1d penetrating in a direction orthogonal to the screen SC. The lengths of the cylindrical portions 143a-143d are equal to one another, and the lengths of the through holes H1a-H1d are equal to one another. The inside diameters of the through holes H1a-H1d are equal to one another.
Into each of the through holes H1a-H1d, an insert nut 16 shown in FIG. 4(A) or FIG. 4(B) is inserted. The insert nut 16 is made of brass (iron or stainless steel may be possible), and has a nut body 161 with a through hole H2. At one end of the longitudinal direction of the nut body 161, a flange 162 with an enlarged diameter is formed, and at the other end of the longitudinal direction of the nut body 161, a reduced diameter portion 163 with a reduced diameter is formed. On an outer wall of the nut body 161, circumferential grooves are formed, and on an inner wall of the nut body 161, a spiral groove is formed. On inner walls of the flange 162 and the reduced diameter portion 163, spiral grooves are also formed, and the grooves are continuous to the groove of the inner wall of the nut body 161.
The outside diameter of the nut body 161 is slightly larger than the inside diameter of each of the through holes H1a-H1d. The outside diameter of the flange 162 is larger than the inside diameter of each of the through holes H1a-H1d. The outside diameter of the reduced diameter portion 163 is slightly smaller than the inside diameter of each of the through holes H1a-H1d. The inside diameter of the nut body 161 is smaller than the inside diameter of each of the through holes H1a-H1d by the dimension corresponding to the thickness of the nut body 161. The length of the nut body 161 is approximately equal to each of the lengths of the through holes H1a-H1d. 
More specifically, the outside diameter and the inside diameter of the nut body 161 are 8.3 mm and 6.0 mm, respectively. The outside diameter of the flange 162 is 10.0 mm, and the outside diameter of the reduced diameter portion 163 is 8.0 mm. Furthermore, the length of the nut body 161 is 7.4 mm, and the length (thickness) of the flange 162 is 0.8 mm, and the length of the reduced diameter portion 163 is 1.8 mm.
The insert nut 16 is inserted into each of the through holes H1a-H1d from the rear surface of the back cabinet 14 as shown in FIG. 5. The inserted insert nut 16 is connected with the back cabinet 14 by thermal fusion. More specifically, circumferential grooves formed on the outer wall of the nut body 161 are connected with the inner wall of each of the through holes H1a-H1d by thermal fusion.
In the attached state, the flange 162 is exposed from each of the through holes H1a-H1d to the outside. Furthermore, the through hole direction of the through hole H2 is coincident with the through hole direction of each of the through holes H1a-H1d. In addition, the central axis of the through hole H2 is coincident with the central axis of each of the through holes H1a-H1d. 
Referring to FIG. 6, a wall-mounting fitting 18 is furnished with a platelike fitting 18a. A fitting 18a is in the form of a rectangle, and at the four corners, through holes H3a-H3d are provided. The through hole direction of each of the through holes H3a-H3d is coincident with the thickness direction of the fitting 18a The distance from the through hole H3a to the through hole H3b is coincident with the distance from the through hole H1a to the through hole H1b, and the distance from the through hole H3c to the through hole H3d is coincident with the distance from the through hole H1c to the through hole H1d. In addition, the distance from the through hole H3a to the through hole H3c is coincident with the distance from the through hole H1a to the through hole H1c, and the distance from the through hole H3b to the through hole H3d is coincident with the distance from the through hole H1b to the through hole H1d. Additionally, the inside diameter of each of the through holes H3a-H4d is approximately coincident with the inside diameter of the through hole H2.
The mounting fitting 18 is mounted on the back cabinet 14 in the following manner. First, the mounting fitting 18 is arranged on the front surface of the back cabinet 14 such that the through holes H3a-H3d are communicated with the through holes H1a-H1d, respectively. A bolt 20 has a spiral thread to be engaged with the spiral groove of the through hole H2 of the insert nut 16. The bolt 20 is inserted into each of the through holes H3a-H3d from the front surface of the fitting 18a, and then screwed in the through hole H2 of the insert nut 16 thermally fused to the back cabinet 14. That is, the bolt 20 is engaged with the insert nut 16 through the fitting 18a. The back cabinet 14 attached with the mounting fitting 18 is mounted on the monitor body 12 in the manner shown in FIG. 7.
As understood from the above description, the monitor body 12 has the screen SC for displaying a video. The cabinet 14 has the through hole H1 penetrating in a direction orthogonal to the screen SC. The back of the monitor body 12 is covered with the cabinet 14. The insert nut 16 has the through hole H2 with an inside diameter smaller than that of the through hole H1, and is inserted into the through hole H1 such that the through hole direction of the through hole H2 is along the direction orthogonal to the screen SC. The wall-mounting fitting 18 has the through hole H3 to be communicated with the through hole H2. On the front surface of the cabinet 14, the wall-mounting fitting 18 is provided. The bolt 20 is engaged with the through hole H2 via the through hole H3.
By utilizing the through hole H1 provided on the rear surface of the cabinet 14 for the purpose of wall-mounting, it is possible to make the monitor body 12 thinner and improve a degree of flexibility in design. Furthermore, the bolt 20 is engaged with the through hole H2 of the insert nut 16 inserted into the through hole H1 of the cabinet 14, and the monitor body 12 and the cabinet 14 are supported by the bolt 20 and the insert nut 16. This makes it possible to improve a tolerance with respect to downward forces.
It should be noted that in this embodiment, the through hole direction of each of the through holes H1a-H1d is the direction orthogonal to the screen SC, but is not limited to the orthogonal direction to the screen SC as long as it is the direction crossing the screen SC. Furthermore, in this embodiment, each of the embossing portions 141 and 142 extends in the vertical direction, but it is not limited thereto if it has a vertical component (it is not the horizontal direction). Thus, an embossing portion may be formed like drawing X, for example.
Although the present invention has been described and illustrated in detail, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, the spirit and scope of the present invention being limited only by the terms of the appended claims.
