In this case, rainwater that has fallen on the first connection piece 22 can be guided to the inclined surface and flow down to a position away from the wall surface.
In the center of the first connecting piece 22, one second elongated hole 24 extending in the front-rear direction is formed as one configuration of the fixing means.

[First corner rib]
In the present embodiment, a first corner rib R <b> 1 protruding from the inner corner is formed at the corner where the wall surface mounting piece 21 and the first connecting piece 22 are bent.
The first corner rib R1 has a substantially triangular pyramid shape, and protrudes toward the inner corner (upward in FIGS. 1 and 2), and is formed to be a recess on the opposite side (lower in the figure). A pair of left and right corners are arranged in a balanced manner.
As long as the strength of the support piece 2 can be increased, the first corner rib R1 can be provided in any number, such as one formed at the center of the corner and three equally formed. .

[Inner base]
The inner base 3 includes a second connecting piece 31 that is fixed to the first connecting piece 22 so as to overlap with the first connecting piece 22 and an inner fixing piece 4 that is bent downward at the front end of the second connecting piece 31 and extends to the left and right. ing.
In the present embodiment, a second corner rib R <b> 2 is formed at the corner of the second connecting piece 31 and the inner fixed piece 4 that is bent.
The second corner rib R2 has a substantially triangular pyramid shape, and protrudes to the inner corner side (downward in FIGS. 1 and 2), and is formed to be a recess on the opposite side (upper side in the figure). A pair of left and right corners are arranged with good balance.
As long as the strength of the support piece 2 can be increased, the first corner rib R1 can be provided in any number, such as one formed at the center of the corner and three equally formed. .

[Second connecting piece]
The second connecting piece 31 is made of a plate that can be vertically overlapped with the first connecting piece 22 corresponding to the first connecting piece 22, and the second long hole 24 is located in the middle of the second connecting piece 31. As a corresponding configuration of the fixing means, one screw hole 34 is formed at a position overlapping with the screw.
In addition, on the left and right side surfaces of the second connecting piece 31, a restraining piece 32 that rises upward is integrally formed.

Accordingly, when the second connecting piece 31 is applied along the back surface of the first connecting piece 22, the first connecting piece 22 and the second connecting piece 31 are fitted to the first connecting piece 22 by the restraining piece 32. Positioning in the left-right direction is performed mutually.
Then, the second long hole 24 of the first connecting piece 22 and the screw hole 34 of the second connecting piece 31 are aligned, and the second connecting piece 31 is adjusted within a range in which the screw hole 34 is aligned with the second long hole 24. The length is adjusted by moving back and forth, and the first connecting piece 22 and the second connecting piece 31 are fixed by screwing with the connecting screw 6 at the optimum position.

In the present embodiment, the first connecting piece 22 is stacked on the second connecting piece 31, but conversely, the first connecting piece 22 may be stacked below the second connecting piece 31.
Further, one of the second long hole 24 and the screw hole 34 may be formed in the first connection piece 22 and the other may be formed in the second connection piece 31.
Further, as a length adjustment means in the front-rear direction, for example, a plurality of holes arranged in front and rear are provided instead of the second long holes, a desired hole is selected, and the screw hole is aligned with the screw hole and screwed. It is also possible to use a length adjusting structure.
Similarly, the restraining piece 32 is provided on either the first connecting piece 22 or the second connecting piece 31 as long as the first connecting piece 22 and the second connecting piece 31 can be positioned in the left-right direction. It may be provided on both sides.

[Inner fixed piece]
The inner fixed piece 4 is bent at an obtuse angle θ with respect to the second connecting piece 31 downward at the front end of the second connecting piece 31.
Accordingly, the second connecting piece 31 is inclined at substantially the same angle so as to abut the first connecting piece 22 without a gap.
In addition, a pair of left and right screw holes 42 are formed in an intermediate portion of the inner fixing piece 4 that connects between the left and right first receiving portions 41.

[First receiving part]
A pair of first receiving portions 41 are integrally formed at the left and right ends of the second connecting piece 31 at positions protruding beyond the second connecting piece 31 outward.
In the case of the present embodiment, the first receiving portion 41 has a substantially arc-shaped cross section with the opening facing forward, and abuts against the back surface of the standing tube, and further has a small diameter (20A). A small-diameter arc-shaped receiving portion is provided so as to hook the tube.
In the center of the first receiving portion 41, a band-shaped inner receiving portion rib R3 is formed so as to project inward along the longitudinal direction, thereby increasing the strength of the first receiving portion 41.
The front and back of the vertical pipe correspond to the front and back of the meter, with the display window side of the meter as the front side and the opposite side (wall side) as the back side.

[Outside fixed piece]
The outer fixing piece 5 is formed of a plate that can be overlapped with the inner fixing piece 4 in the front-rear direction corresponding to the inner fixing piece 4.
A pair of second receiving portions 51 are integrally formed at both left and right ends.
A pair of left and right screw holes 52 are formed in the middle portion of the outer fixing piece 5 connecting the left and right second receiving portions 51 so as to be aligned with the screw holes 42 of the inner fixing piece 4.
In the center of the second receiving portion 51, a band-shaped outer receiving portion rib R4 is formed so as to project outward along the longitudinal direction, thereby increasing the strength of the second receiving portion 51.

Therefore, the first receiving portion 41 is brought into contact with the back surface of the vertical pipe without a substantial gap, and the second receiving portion 51 is similarly brought into contact with the surface of the vertical pipe without a substantial gap. The screw holes 52 can be passed through the screw holes 42 so that the wide surfaces of the outer fixing piece 5 and the inner fixing piece 4 face each other.
At this time, the inner fixing piece 4 and the outer fixing piece 5 are arranged such that the first receiving portion is fixed at the time of fixing with reference to the case of the small diameter so that the diameter of the vertical tube can be fixed with either the large diameter (25A) or the small diameter (20A). It is necessary to set the shapes of the first receiving portion 41 and the second receiving portion 51 so that the portion 41 and the second receiving portion 51 do not interfere with each other and cannot be sufficiently fixed.

Thus, as in JP-A-2006-317431, when the diameter of the vertical pipe is small (20A), the first receiving portion 41 abuts the back side of the vertical pipe with almost no gap, and the front side of the vertical pipe is The 2nd receiving part 51 can collide with the surface of a part of the center, and can fix a standing pipe.
When the diameter of the vertical pipe is large (25A), the second receiving part 51 abuts on the front side of the vertical pipe with almost no gap, and the back side of the vertical pipe has the first receiving part 41 at at least two locations. The standpipe can be fixed.
Here, the large-diameter side receiving portion, in this embodiment, the second receiving portion 51 has an arc shape with a substantially semicircular cross section, and the small-diameter side receiving portion, in this embodiment, the first receiving portion 41 is the second receiving portion. An arc shape smaller than the portion 51 is preferable because the entire contact surface with the vertical pipe can be increased.

In the above embodiment, the first receiving portion outer fixing piece 5 and the second receiving portion have a circular arc shape in cross section, but may be a polygonal shape with one side open, in other words, at least in a plurality of locations, it collides with the standpipe. As long as the vertical pipe is restrained so as not to move, it is sufficient.
In the above embodiment, the screw hole 42 of the inner fixing piece 4 and the screw hole 52 of the outer fixing piece 5 are arranged symmetrically with respect to the longitudinal center line of the inner fixing piece 4 and the outer fixing piece 5. Therefore, when the diameter of the vertical pipe is small (20A), the gap between the inner fixed piece 4 and the outer fixed piece 5 can be narrowed and fitted without any gap at the time of installation, but the diameter of the vertical pipe is large. In the case of the diameter (25A), a gap S is generated between the inner fixed piece 4 and the outer fixed piece 5 as indicated by a dotted line in FIG.
When screwing in with a fixing screw, if it is tightened too much, a load is applied to an intermediate portion of the screw hole 52 of the outer fixing piece 5.

Therefore, a pair of guide hole portions 8a and 8b are provided.
Further, the guide post portions 9a and 9b are projected from the outer fixed piece 5 at positions that are asymmetric with respect to the center point C when the outer fixed piece 5 is rotated 180 degrees.
The guide hole portions 8a and 8b are arranged at positions where the guide column portions 9a and 9b can be inserted into alignment with the guide column portions 9a and 9b when the outer fixed piece 5 is in the normal position. .

  Thereby, when the diameter of the vertical pipe is small (20A), the outer fixed piece 5 is brought close to the inner fixed piece 4 in the same posture, and the guide column portions 9a and 9b are moved into the guide hole portions 8a and 8b. The fixing screw 7 is inserted and fixed in the screw holes 52 and 42 in which the inner fixing piece 4 and the outer fixing piece 5 are aligned.

When the diameter of the vertical pipe is large (25A), the outer fixed piece 5 is rotated 180 degrees to the reverse position.
As a result, the guide post portions 9 b and 9 a of the outer fixed piece 5 do not align with the guide hole portions 8 a and 8 b of the inner fixed piece 4, and the guide post portions 9 b and 9 a abut against the wall surface of the inner fixed piece 4. Thus, the guide support post portion functions as a support post of the outer fixed piece 5 across the gap between the inner fixed piece 4 and the outer fixed piece 5.

Since the positions of the screw holes 42 and 52 provided in the inner fixing piece 4 and the outer fixing piece 5 do not change even if the outer fixing piece 5 is rotated 180 degrees, the fixing screw 7 is inserted and fixed to the screw holes 52 and 42. .
As a result, even if a large gap S is generated between the inner fixing piece 4 and the outer fixing piece 5, the guide post portions 9b and 9a support the outer fixing piece 5. Therefore, even if the fixing screws 7 are tightened, the outer fixing is performed. There is no possibility that the piece 5 is deformed.

In the above embodiment, the inner fixing piece 4 is provided with the guide hole portion and the outer fixing piece 5 is provided with the guide post portion. However, on the contrary, the inner fixing piece 4 is provided with the guide support portion, and the outer fixing piece 5 is provided. Alternatively, a guide hole may be provided.
Moreover, in the said Example, although two guide hole parts and the guide support | pillar part were arrange | positioned in the horizontal direction, you may form three or more.

Further, in the above embodiment, as illustrated in FIG. 8, the case where the guide post portion is cut and raised in a U shape from the outer fixed piece is illustrated, but a separate protruding piece is fixed by welding or the like. It may be a thing, or a thing fixed with a screw or a pin.
Further, in the present invention, the configuration exemplified in each embodiment may be appropriately replaced and used.

The meter support fitting 1 of the present embodiment has the above-described configuration, and is reinforced by each of the first corner rib R1, the second corner rib R2, the inner receiving rib R3, and the outer receiving rib R4. The thickness of the material can be reduced or miniaturized as compared with the conventional meter support fitting without the reinforcing rib.
Further, the screw holes 42 and the screw holes 52 have a threading length of 4 to 5 mm by performing burring even if the plate thickness of the inner fixing piece 4 and the outer fixing piece 5 is reduced to, for example, 2.0 mm. It was confirmed that three or more female threads could be formed.
And when the plate thickness of each member of the conventional meter support bracket is 3.0mm, even if the plate thickness is reduced to 2.0mm, the vibration test based on the microcomputer meter inspection regulations is carried out, and the earthquake resistance performance in three directions and two directions Was confirmed to be equivalent to the conventional product with no decrease in seismic strength.

Further, the inner receiving portion rib R3 and the outer receiving portion rib R4 can improve the bending rigidity of the first receiving portion 41 and the second receiving portion 51 with respect to the conventional product.
Further, by shifting the position of the second long hole 24 and shortening the length of the restraining piece 22 and the second connecting piece 31 by 15 mm compared to the conventional product, the size could be reduced.
As a result, the material cost can be reduced to 2/3, the total cost can be reduced by about 10% even if the increase in processing cost and mold production cost is subtracted, and the workability can be facilitated by light weight and downsizing. It was.
In addition, it goes without saying that various design changes can be made without departing from the scope of the present invention.

  In the above-described embodiment, the meter support bracket for fixing the gas meter stand pipe has been described. However, the present invention is not limited to the gas meter and can be applied to other uses of the meter support bracket provided on the stand pipe.
