Description

  The present invention relates to an improvement of a meter support fitting for mounting and fixing a gas meter along a wall portion of a house or the like.

2. Description of the Related Art Conventionally, as a gas meter mounting structure, a wall mounting type structure in which each gas pipe is fixed to a wall surface and the gas meter is installed along the wall surface is known.
For example, in the pipe unit disclosed in Japanese Patent Laid-Open No. 7-333032, two gas pipes (stand pipes) whose end portions are connected to the inlet side and the outlet side of the gas meter are arranged in parallel, and the space between these gas pipes An interval holding member is provided at the both ends, and both ends of the interval holding member and each gas pipe are connected by a pipe clamp.
As a result, the two gas pipes can be held in parallel in advance, so that the gas pipe can be attached to the wall surface simply by fixing the spacing member to the wall surface by means such as screws.
However, in the conventional support fitting, when fixing the wall fixing screw, the support fitting along the wall may be lifted and fixed with insufficient strength, and there is a drawback that it is difficult to construct.
In addition, since there are a plurality of gas pipes (standing pipes) (for example, 20A and 25A) and the sizes of the clamps of the support brackets and the latching portions are different, it is necessary to stock those sizes.

Japanese Patent Laid-Open No. 2004-69565 discloses that a gas meter mounting bracket for fixing a pair of left and right gas pipes of a gas meter to a wall surface is provided with a long window-shaped mounting hole at one place on a base or a wall surface mounting portion. A slide adjustment fixing mechanism is configured so that the base wall and the wall surface mounting portion can be screwed to each other through the mounting hole by a fastening bolt so that the wall surface mounting portion can be slidably adjusted to the base body. There is disclosed a configuration in which a slide guide portion for guiding the slide adjustment movement of the edge portion of the base is provided on the base or the wall surface mounting portion.
However, in this case as well, it is impossible to suppress the lifting of the support fitting along the wall, and it is necessary to prepare upright pipes having different diameters of different sizes.

In addition, the purpose of being able to fix the vertical pipes with different diameters with the same meter mounting bracket has been realized.

[Reference example]
The following is a reference example in which the meter mounting bracket of the present invention is applied to a wall mounting type of a gas meter, and the configuration in which the fixing position of the first connecting piece and the second connecting piece can be adjusted in the front-rear direction is omitted. This will be described with reference to the drawings.
As shown in FIGS. 1 to 3, the meter mounting bracket 1 is opposed to an angle-shaped support piece 2, an inner base 3 fixed to the support piece 2, and an inner fixed piece 4 of the inner base 3. The outer fixed piece 5 is made up of.

[Supporting piece]
The support piece 2 is made of an angle-shaped metal plate, and includes a wall surface attachment piece 21 that makes a wide surface contact along the wall surface, and a first connection piece 22 that is bent at the lower end of the wall surface attachment piece 21 and extends forward. It has become.

[Wall mounting piece]
The wall surface attachment piece 21 is formed in a rectangular shape extending horizontally, and is provided with a pair of left and right first elongated holes 23 extending in the horizontal direction.

[First connecting piece]
If the 1st connection piece 22 bends with respect to the wall surface attachment piece 21 and protrudes ahead, the bending angle will not be ask | required, but it is preferable to bend so that it may incline at obtuse angle (theta). 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.
Next, in this reference example, as one configuration of the fixing means, one second long hole 24 extending in the front-rear direction is formed in the center of the first connecting piece 22.

[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.

[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 reference example, 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 this reference example, the first receiving portion 41 has a substantially arc shape in cross section with the opening facing forward, and abuts against the back surface of the standpipe, and further has a small diameter (20A). A small-diameter arc-shaped receiving portion is provided so as to hook the tube.
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.

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 so 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 pipe can be fixed with the large diameter (25A) or the small diameter (20A). It is necessary to set the shapes of the first receiving portion 41 and the first receiving portion 51 so that the portion 41 and the first receiving portion 51 do not interfere with each other and cannot be sufficiently fixed.

As a result, as shown in FIG. 4 (a), 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.
As shown in FIG. 4B, when the diameter of the vertical pipe is large (25A), the second receiving portion 51 abuts the front side of the vertical pipe with almost no gap, and the back side of the vertical pipe is The 1 receiving part 41 collides at at least two places, and can fix a standing pipe.
Here, the large diameter side receiving part, in this reference example, the second receiving part 51 has an arc shape with a substantially semicircular cross section, and the small diameter side receiving part, in this reference example, the first receiving part 41 in the second receiving part. 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 reference example, the shape of the first receiving portion outer fixing piece 5 and the second receiving portion is a circular arc shape in cross section, but it 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 reference example, 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, in the meter mounting bracket 1 of the first embodiment shown in FIGS. 7 to 8, 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. .
Other configurations are the same as those of the reference example, and thus the description thereof is omitted.

  Thereby, when the diameter of the vertical pipe is small (20A), the outer fixing piece 5 is brought close to the inner fixing 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, as shown in FIG. 9A, a plurality of guide hole portions 8 a and 8 b and guide column portions 9 a and 9 b are provided in the vertical direction, not in the horizontal direction, and the center point c of the outer fixed piece 5 is provided. It is good also as a structure which arrange | positions by shifting up and down as shown in (b), and arrange | positioning by shifting up and down by asymmetrical asymmetry.

FIG. 10 shows a different embodiment in which one guide hole 8 and one guide post 9 are provided.
Even in this case, even if a large gap S is generated between the inner fixing piece 4 and the outer fixing piece 5, the guide post 9 supports the outer fixing piece 5. There is no risk of deformation.

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.
Moreover, in this invention, you may replace and use the structure illustrated by each Example suitably.
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.
