Description

  The present invention is a wall-side plate for a TV wall that is mounted on the wall side when a thin wall-mounted TV is mounted on the wall, particularly when the TV screen frame after mounting is displaced from the horizontal and vertical lines. The present invention relates to a wall-side plate for hanging a TV wall, in which a mounting angle around an axis perpendicular to the wall is finely adjusted so as to match a horizontal and vertical line.

  In recent years, thin and large-screen televisions such as liquid crystal televisions and plasma televisions have become popular in ordinary homes. Since these televisions are large in size, they tend to be attached to the wall surface in order to ensure a living space while also functioning as an interior. In response to this, various mounting brackets and support devices for mounting a television to a wall surface have been proposed (see, for example, Patent Documents 1 to 6).

  Each of the television wall hanging supports proposed in these patent documents has a wall-side fixing member (wall-side plate) as a base fixed to a wall surface, and a television mounting body of various shapes is attached to the back of the television. And the system which attaches a television to a wall surface by fixing to a wall side fixing member which fixed the television mounting body to the wall surface with a volt | bolt, hanging with a hook, or connecting with a movable connection tool is employ | adopted. By the way, if the frame of the attached TV screen is tilted with a slight deviation from the horizontal and vertical lines, it is difficult to see and anxious.

  FIG. 10 is a diagram showing how to attach a conventional wall-side fixing member (wall-side plate) 50 to the wall surface 51 as an example. The wall-side plate 50 is provided with two upper and lower hole rows 53 in which a number of holes for passing the fixing bolts 52 are provided at regular intervals in the horizontal direction. In the state where the longitudinal direction of the wall side plate 50 is horizontal and pressed against the wall surface 51, four holes through which the fixing bolts 52 are passed are selected, and the wall surface 51 is marked through the selected holes. Next, the wall side plate 50 is removed, and a pilot hole is provided in the marked portion with a drill. When the pilot hole is made, the wall side plate 50 is returned to the original position, and the fixing bolt 52 is screwed into the pilot hole through the four holes to fix the wall side plate 50 to the wall surface 51.

  However, in the case of such an attachment method, it is difficult to make a drill so that the four pilot holes are completely aligned on the horizontal and vertical lines. Further, when the television side bracket is attached to the rear surface of the television, the television side bracket may be attached in an inclined state and tilted. When such an inclination occurs, the television screen after installation becomes inclined around an axis perpendicular to the wall surface. In the conventional method using the wall-side fixing member (wall-side plate), when such an inclination occurs, the four pilot holes are re-opened, or the TV-side bracket is reattached to the back of the TV. Need arises.

Further, the upper first folded portion and the lower first folded portion are folded at right angles to the outside parallel to the bottom surface portion at right angles to the upper second folded portion. A bent portion and a lower second bent portion are formed, and the upper side hole row and the lower side hole row that are continuous in the horizontal direction at regular intervals are symmetrically positioned with respect to the vertical center line of the bottom surface portion. In addition, the upper horizontal hole row, the lower horizontal hole row and the vertical end of the bottom portion Are formed with a plurality of arc-shaped holes centered on the bottom center point that is the intersection of the vertical center line and the horizontal center line at different radial distances from the bottom center point. It is the wall side plate for television wall hangings characterized by the above-mentioned.

  According to such a configuration, when a quadrangle formed by connecting four wall-side plate fixing pilot holes provided on the wall surface is tilted from the horizontal line, or when the TV-side bracket is tilted and attached to the back of the TV However, since the arc-shaped hole in the bottom surface is formed in an arc shape centering on the bottom surface center point that is the intersection of the vertical center line and the horizontal center line of the bottom surface part, the generated tilt is corrected. The wall side plate can be tilted and attached in the direction to be. This has the advantage that the frame of the TV screen can be accurately parallel to the horizontal and vertical lines without re-opening the pilot holes or reattaching the TV-side bracket.

As shown in FIG. 1, the wall side plate 1 is formed by bending a metal plate into a substantially U shape having a bottom surface portion 2 having a horizontally long rectangular shape in a plan view and a wide side view. It is attached in a state where the horizontally long direction is horizontal and the bottom surface portion 2 is in contact with the wall surface.

  Both ends in the vertical direction of the bottom surface 2 of the horizontally long rectangle are bent at a right angle to form a narrow upper first bent portion 3 and a lower first bent portion 4 so as to have a substantially U-shaped cross section. Further, the top end portions of the upper first bent portion 3 and the lower first bent portion 4 are bent at right angles to the outside in parallel to the bottom surface portion 2, so that the narrower upper second bent portion 5, lower lower first portion Two bent portions 6 are formed.

  On the horizontally long bottom surface portion 2, an upper horizontal hole row 8 and a lower horizontal hole row 9 which are continuous in the horizontal direction at regular intervals are formed at symmetrical positions with respect to the vertical center line of the bottom surface portion 2. Each hole of the upper side hole row 8 and the lower side hole row 9 is formed to have a width through which a bolt for fixing to the wall surface passes. Further, as a feature of the wall side plate 1 of the present embodiment, there is an upper and lower portion of the bottom surface portion 2 between the upper side hole row 8 and the lower side hole row 9 and the vertical end of the bottom surface portion 2 as shown in FIG. A plurality of arc-shaped holes 11 centering on the bottom surface center point 10, which is the intersection of the direction center line and the horizontal center line, are formed at different radial distances from the bottom surface center point 10. Each arcuate hole 11 is also formed to have a width through which a bolt for fixing to the wall surface passes. The bottom surface portion 2 is fixed to the wall surface by screwing into 4 to 6 pilot holes provided on the wall surface with fixing bolts through the holes of the upper side hole row 8, the lower side hole row 9, or the arc-shaped holes 11. Is fixed using an arc-shaped hole 11.

  FIG. 4 is an appearance of an example of a TV-side bracket attached to the back side of the flat-screen TV. The TV-side bracket 13 includes a fixing bracket 14 provided with a number of holes for screwing and fixing to the rear surface of the TV, a hanging bracket 17 provided with two hooks 15 at the upper part, and a drop-off preventing screw 16 at the lower part. It consists of and. The fixing bracket 14 has a U-shaped cross section, and a plurality of round holes 19 through which fixing screws are passed are provided in the upper part from the center of the surface in contact with the television, and the lower part from the center is provided in the lower part. In this case, a plurality of elongated holes 20 through which the fixing screws are passed are provided in the vertical direction.

  The hanging bracket 17 is composed of two parallel plates 17a having a central portion at the back connected by a horizontal plate. A hook 15 for hanging on the upper second bent portion 5 of the bottom surface portion 2 is formed on the upper portion of each plate 17a. A horizontal portion 21 bent toward the mating plate 17a is formed at the lower portion, and a drop-off prevention screw 16 is screwed into the horizontal portion 21 upward from below. The drop-off prevention screw 16 can adjust the length of the thread portion protruding upward from the horizontal portion 21 by adjusting the screwing.

  In the middle of the two plates 17a of the hanging bracket 17, two arc-shaped long holes 22 are provided symmetrically with respect to the vertical center line, and a round hole is also provided in the vertical center. The fixing bracket 14 is provided with an arc-shaped long hole 23 in the vertical direction at the center. Between the left and right plates of the fixing bracket 14, two fixed shafts 25 are fixedly attached through the arc-shaped elongated holes 22 of the two plates 17a. Further, the fixing bracket 14 and the two plates 17a are passed through the arc-shaped elongated hole 23 in the center of the fixing bracket 14 and the central circular hole of the two plates 17a, so that the fixing bracket 14 and the two plates 17a are tightened so as not to move. A tightening bolt 26 that can be tightened is attached. In the state where the tightening bolts 26 are loosened, the two plates 17a are moved with respect to the fixing bracket 14 (the angle between them) by passing the two fixed shafts 25 through the arc-shaped elongated holes 22 by moving the two plates 17a. It can be adjusted by changing the position. At that time, the fastening bolt 26 moves in the arc-shaped elongated hole 23 in the center portion in accordance with the movement of the two plates 17a. When the two plates 17a are moved in this way to determine the postures of the two plates 17a with respect to the fixing bracket 14 (the angle between them), the fastening bolts 26 are tightened to fix the postures.

  As shown in FIG. 5, two hanging brackets 17 are attached to the left and right of the rear surface of the television 30 using a number of round holes 19 and long holes 20 of the fixing bracket 14. When attaching the hanging bracket 17 to which the TV is fixed to the wall-side plate 1 fixed to the wall surface, the falling prevention screw 16 of the hanging bracket 17 is removed. Then, as shown in FIG. 6, the two hooks 15 of the hanging bracket 17 are hung on a desired position of the upper second bent portion 5 of the wall-side plate 1 attached to the wall surface 31. Next, the drop-off prevention screw 16 is attached to the hanging bracket 17, and the upper tip portion of the screw enters between the lower second bent portion 6 of the bottom surface portion 2 of the wall side plate 1 and the wall surface 31, and the tip is Screw to the position where it contacts the lower first bent portion 4 of the wall side plate 1. Thereby, the television side bracket 13 to which the television is fixed is prevented from coming off the wall side plate 1 and falling off. The angle between the fixing bracket 14 and the hanging bracket 17 of the television side bracket 13 can be adjusted by changing the tightening position of the tightening bolt 26 as described above. Therefore, the elevation angle of the attached television screen can be adjusted to a desired angle by the adjustment.

  The wall side plate 1 of the present embodiment configured as described above is attached to the wall surface as follows. As a bolt passage hole of the bottom surface portion 2 used for fixing the wall side plate 1 to the wall surface with a bolt, either the upper side hole row 8 or the lower side hole row 9 of the bottom surface portion 2 can be used. . However, in the wall side plate 1 of this embodiment, two upper and lower arc-shaped holes 11 provided outside the upper side hole row 8 and the lower side hole row 9 are used.

  As shown in FIG. 7, the bottom plate 2 is pressed against the wall surface with the wall-side plate 1 in the horizontal direction being horizontal. In this state, four arc-shaped holes 11 at positions where a quadrangular shape is to be formed are selected, and four marks 35a, 35b, 35c, and 35d are attached to the wall surface through the central portions of the holes. Next, the wall side plate 1 is removed, and a pilot hole is drilled at the positions of four marks 35a, 35b, 35c, and 35d attached to the wall surface shown in FIG. When the pilot holes are made, the wall side plate 1 is returned to the original position, and mounting bolts are screwed into the pilot holes through the four arc-shaped holes 11 to fix the wall side plate 1 to the wall surface.

  As a problem that often arises when the wall side plate 1 is fixed to the wall surface in this way, the lines connecting the pilot holes provided at the positions of the four marks 35a, 35b, 35c, 35d do not ride on the horizontal and vertical lines. As shown in (2) of FIG. 8, the quadrilateral may be inclined from the horizontal line. The main cause is that when the wall-side plate 1 was pressed against the wall surface in order to attach the four marks 35a, 35b, 35c, 35d, the lateral direction of the wall-side plate 1 was not completely horizontal. is there. Other causes include misalignment when marking the wall surface using the arc-shaped hole 11 and misalignment of the drill when providing a pilot hole with a drill.

  When the television side bracket 13 is attached in a state where the four squares connecting the pilot holes are inclined from the horizontal line, the attached television screen is slightly inclined around the axis perpendicular to the wall surface. The same applies to the case where the television side bracket 13 is attached in an inclined state when the television side bracket 13 is attached to the rear surface of the television. In such a case, in the wall side plate of the present embodiment, the arc-shaped hole 11 of the bottom surface portion 2 is centered on the bottom surface center point 10 that is the intersection of the vertical center line and the horizontal center line of the bottom surface portion 2. Since they are arranged in an arc shape, as shown in FIG. 9, they can be attached horizontally even if a quadrilateral connecting four pilot holes is inclined from the horizontal line. When the TV-side bracket 13 is attached to the rear surface of the TV with an inclination and the TV is inclined, the TV can be attached horizontally by fixing the bottom surface portion 2 in a direction to correct the inclination. This correction is also possible because the arc-shaped hole 11 is formed on an arc centered on the bottom surface center point 10. When the wall-side plate of this embodiment is adopted, the frame of the installed TV screen becomes horizontal and vertical without re-opening the pilot holes or re-installing the TV-side bracket by such mounting method and correction. The TV can be attached to the wall.
