Each combination hole is opened for combination.

The arm portion 5 is screwed into the hole portion 8 opened in the side surface of the back cover 2 with the adjusting fixture 6 and the arm portion 5 is screwed into the combination hole 12 opened in the wall fixing bracket 4. The back cover 2 and the wall fixture 4 are connected by screwing with a combination fixture 7. The wall fixing bracket 4 and the arm portion 5 are configured to be freely rotatable around the combination fixture 7 as a rotation center, and the back cover 2 and the arm portion 5 are freely set around the adjustment fixture 6 as a rotation center. It is set as the structure which can be rotated. Further, the length of the arm portion 5 is configured to be longer than at least the depth of the back cover 2.

  In addition, the rotation angle of the arm portion 5 is an angle represented by a parallel line on the ground surface using the apexes of the corners as a combination fixture 7 and a center line of the arm portion 5.

Next, the attachment method in the case of the work site of FIG. 1 is demonstrated.
When the installation distance between the housing 1 and the wall surface 3 is a short distance, the wall fixture 4 and the wall surface 3 are fixed by the wall fixture 10 according to the installation distance. At that time, as the installation distance of the arm portion 5 is shortened, the angle between the wall fixing bracket 4 and the arm portion 5 is increased and the fixing position of the wall fixing bracket 4 and the wall surface 3 is lowered. The arm portion 5 is rotated about the combination fixture 7 as a center of rotation, and the back cover 2 and the arm portion 5 are rotated about the adjustment fixture 6 as a center of rotation, so that the wall fixture 4 and the arm portion 5 are interposed. Thus, the housing 1 and the wall surface 3 can be fixed.

It is a right-angle long hole which consists of a vertical long hole part opened to the other end.

And since the hole part 8 is made into the right-angle long hole 13, since the distance with the wall surface 3 can be suitably moved by the range of the right-angle long hole 13, even if the distance with the wall surface 3 changes with installation places. Can be fixed securely.

Further, the length of the arm portion 5 is substantially the same as the length obtained by connecting one end of the right-angle long hole 13 and the other end of the long hole 13 with a straight line, so that the arm portion 5 is longer than the depth of the back cover 2. And the arm part 5 shall be piled up on the side surface of the back cover 2 without protruding from the back cover 2.

Next, when the hole portion 8 is changed to the right-angle long hole 13, a mounting method in the case of the work site in FIG. 4 will be described.
When the installation distance between the housing 1 and the wall surface 3 is short, the wall fixture 3 is fixed to the wall surface 3 having the same height as the upper portion of the right-angle elongated hole 13. Then, the adjustment fixture 6 of the arm portion 5 is slid in the range of the right-angle long hole 13 according to the installation distance, and the arm portion 5 is fixed with the insertion adjustment fixture 6 so as to overlap the side surface of the back cover 2. Thus, the housing 1 and the wall surface 3 are fixed via the wall fixing bracket 4 and the arm portion 5. Further, when the adjustment fixture 6 is slid into the range of the vertical slot of the right-angle slot 13, the wall fixture 4 and the arm 5 are in an angled state, but the wall fixture 4 and the arm 5 are The rear cover 2 and the arm part 5 are rotated about the combination fixing tool 7 as the rotation center, and the housing 1 is interposed via the wall fixing bracket 4 and the arm part 5 by rotating the adjustment fixing tool 6 as the rotation center.

Then, according to the installation distance, the adjustment fixture 6 of the arm unit 5 is slid in the range of the right-angle long hole 13 and is inserted so as to overlap the side surface of the back cover 2 when the installation distance is short. The casing 1 and the wall surface 3 are fixed via the wall fixing bracket 4 and the arm portion 5 by pulling out 5 and fixing it with the adjustment fixture 6. Also, when the adjustment fixture 6 is slid into the horizontal elongated hole portion of the right-angle elongated hole 13, the wall fixing bracket 4 and the arm portion 5 are in a horizontal state, but the wall fixing bracket 4 and the arm portion 5 are fixed in combination. The back cover 2 and the arm 5 are rotated about the tool 7 as a center of rotation, and the housing 1 and the wall surface are interposed via the wall fixing bracket 4 and the arm 5 by rotating the adjustment fixture 6 as the center of rotation. 3 can be fixed.

  As described above, the right-angle elongated hole 13 is provided, and the adjustment fixture 4 and the arm portion 5 are slidable within the range of the elongated hole 13, so that the depth of the elongated hole 13 is equal to that of the first embodiment. In addition, the installation range of the wall fixing bracket 4 can be easily performed because the range in which the wall fixing device 4 can be installed can be widened and the upper portion of the wall surface 3 can be fixed regardless of the installation distance of the housing 1. The length of the arm portion 5 is approximately the same length as a length obtained by connecting one end of the right-angle elongated hole 13 and the other end of the right-angle elongated hole 13 with a straight line, and is fixed to the wall with the combination fixture 7 as the rotation center. The bracket 4 and the arm portion 5 can be rotated, and the back cover 2 and the arm portion 5 can be rotated about the adjustment fixture 6 as a rotation center. Even in this case, it is possible to widen the range in which installation is possible, and it is possible to fix with a simple configuration without changing long and short fittings according to the installation distance.

Next, a third embodiment in which the shape of the back cover 2 is changed will be described with reference to FIG. Here, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

Reference numeral 14 denotes a folding part that folds the end face of the back cover 2 at a right angle in a direction in which the arm part 5 is fixed to the back cover 2, and 15 denotes an insertion port that allows the arm part 5 to be inserted into and withdrawn from the folding part 14. .

When the housing 1 and the wall surface 3 are fixed via the wall fixing bracket 4 and the arm portion 5, the arm portion 5 is inserted into the insertion port 15 opened in the folded portion 14 provided on the end surface of the back cover 2. One piece is fixed by being screwed into a right-angle long hole 13 opened in the back cover 2 with an adjustment fixing bracket.

16 is a cover-side cutout provided in a horizontal direction at a place where the combination fixture 7 that fixes the arm portion 5 and the wall fixing bracket 4 hits the back cover 2 when the arm portion 5 is inserted into the insertion port 15. Numerals 17 and 17 are folding side cutout portions provided in the horizontal direction at a position where the combination fixing tool 12 passes through the folding portion 14 when the arm portion 5 is taken in and out of the insertion port 15.

The cover-side cutout portion 16 inserts the arm portion 5 into the insertion port 15, and the adjustment fixture 6 of the arm portion 5 tries to slide to the other end of the right-angle elongated hole 13. 5 is provided to prevent the adjustment fixture 6 from being slid to the other end of the right-angle elongated hole 13 because the combination fixture 7 that fixes 5 contacts the end of the back cover 2.
Further, the cover-side notch 16 has a size that can accommodate at least the combination fixture 7.

Further, when the arm portion 5 is inserted into the insertion port 15 and the adjustment fixture 6 of the arm portion 5 is slid to the other end of the right-angle elongated hole 13, the folding-side cutout portion 17 5 prevents the adjustment fixture 6 from sliding to the other end of the right-angle elongated hole 13 and allows the combination fixture 7 to pass through the insertion slot 15. It is provided as follows.

Next, the attachment method in the case of the work site of FIG. 8 is demonstrated.
When the installation distance between the casing 1 and the wall surface 3 is almost short, the wall fixture 3 is fixed to the wall surface 3 having the same height as the upper portion of the right-angle elongated hole 13. Then, the adjustment fixture 6 is slid to the other end of the long hole 13. At that time, the wall fixing bracket 4 and the arm portion 5 are in an angled state, but the wall fixing bracket 4 and the arm portion 5 rotate around the combination fixing tool, and the back cover 2 and the arm portion 5 are adjusted and fixed. While the fixture 6 is rotated about the center of rotation, the combination fixture 7 passes through the folded-back cutout portion 17 and is housed in the cover-side cutout portion 16 so that the wall fixing bracket 4 can be used even when there is almost no installation distance. The housing 1 and the wall surface 3 can be fixed via the arm portion 5.

Thus, by providing the cover side cutout portion 16, when the adjustment fixing bracket 6 is slid to the other end of the right-angle long hole 13, the combination fixing tool 7 hits the end portion of the back cover 2, and the right-angle oblong hole 13 can be prevented from sliding to the other end of 13, and the combination fixture 7 can be housed in the cover-side notch 16. Further, by providing the cover-side cutout portion 16, when the adjustment fixture 6 is slid to the other end of the right-angle elongated hole 13, the combination fixture 7 hits the turn-up portion 14 and reaches the other end of the right-angle elongated hole 13. It is possible to prevent the combination fixture 7 from passing through and prevent the slide from being unable to slide. And by providing the cover side notch 16 and the folding notch 17, the adjustment fixture 6 is slid to the other end of the long hole 13 even when there is almost no installation distance, and the combination fixture 7 is moved to the cover side. By storing in the notch part 16, the range which can be installed can be expanded rather than 2nd Embodiment.
