DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to FIGS. FIGS. 1 to 11 show an embodiment of the present invention. A gas meter support device A according to this embodiment includes a support plate (device main body) 2, an inflow pipe 3A, and an outflow pipe 3B. .
The support plate 2 is supported and fixed to the ground or a wall as described later. On the other hand, the inflow pipe 3A and the outflow pipe 3B are rotatably connected and fixed to the support plate 2. A gas meter M is connected to the inflow pipe 3A and the outflow pipe 3B. Therefore, the gas meter M is supported by the support plate 2 via the inflow pipe 3A and the outflow pipe 3B. The gas meter M is
As is well known, as shown by the imaginary line in FIG.
A gas inlet Ma and a gas outlet Mb are provided side by side in the left-right direction on the upper surface (the surface facing the vertical direction).

The support plate 2 is made of a metal plate such as stainless steel having sufficient strength to support the gas meter M, and is disposed horizontally when supporting the gas meter M. As shown in FIGS. 1 to 8, the support plate 2 can be fixed to an upper end portion of a column 4 erected on the ground.
As shown in FIGS. 9 to 11, it is also possible to fix to a vertical wall W of a house via a bracket 5. Of course, the support plate 2 may be fixed to either the support 4 or the bracket 5 only. Alternatively, a portion corresponding to the support column 4 or the bracket 5 may be integrally provided on the support plate 2 in advance and fixed directly to the ground or the wall W.

First, the case where the support plate 2 is fixed to the support column 4 will be described. As shown in FIG. 8, the support plate 2 is supported at the upper end of the support column 4 via a rotary connection mechanism 6. That is, the column 4 has a cylindrical shape, and is erected and fixed on the ground. An annular seating surface 41 that forms a part of a spherical surface is formed at the intersection of the inner peripheral surface and the upper end surface of the column 4. On the other hand, as shown in FIGS. 1B and 8, a support hole (attachment portion) 2
1 is formed. A male screw portion 61 a formed on the upper end surface of the connection shaft 61 of the rotation connection mechanism 6 is provided in the support hole 21.
Are inserted from below. The male screw portion 61a has the support hole 2
1 and the male screw portion 61 that has passed through the support hole 21
A nut 62 is screwed into the upper end of the “a”. And
By tightening the nut 62, the support plate 2 is fixed to the connection shaft 61.

The spherical member 63 is fixed to the lower end surface of the connecting shaft 61 by screwing the male screw portion 63a thereof into the female screw portion 61b formed on the lower end surface of the connecting shaft 61. The spherical member 63 sits on the seating surface 41 at a position below the center. Note that the connecting shaft 61 and the spherical member 63 may be formed integrally.

A cap nut 64 is rotatably arranged on the outer periphery of the spherical member 63. A tapered hole portion 64a is formed on the inner peripheral surface on the upper end side of the cap nut 64 so as to increase its diameter as it goes downward. This tapered hole 64a
Is arranged to contact the spherical member 63 annularly above the center thereof. The cap nut 64 is
When the cap nut 63 is tightened, the spherical member 63 is pressed and fixed to the seating surface 41 of the support 4. As a result, the support plate 2 is fixed to the column 4 via the connection shaft 61 and the spherical member 63. Here, since the spherical member 63 is in spherical contact with the seating surface 41, the angle can be adjusted three-dimensionally by loosening the cap nut 64. Therefore, the angle of the support plate 2 can be adjusted three-dimensionally. As a result, the gas meter M is leveled out. Of course, when the cap nut 64 is tightened, the support plate 2 is maintained in the adjusted angular position.

On the other hand, the case where the support plate 2 is supported on the wall W via the bracket 5 will be described.
As shown in (2), two screw insertion holes (attachment portions) 22 that are separated in the left-right direction are formed at substantially the center of the support plate 2. On the other hand, the bracket 5 is formed by bending a metal plate at a right angle, and has a fixing portion 51 and a support portion 52. The fixing portion 51 is fixed to the wall W by bolts B ₁ , and the support portion 52 is detachably fixed to the lower surface of the support plate 2 by bolts B ₂ inserted into the screw insertion holes 22. Thereby, the support plate 2 is supported and fixed to the wall W.

Next, the connection structure of the inflow pipe 3A and the outflow pipe 3B to the support plate 2 will be described. FIG. 1 (B)
As shown in FIG. 2, two first guide grooves 23A and 23B extending rearward are formed on both left and right sides of the front surface of the support plate 2, respectively. The distance between the first guide grooves 23A and 23B is the same as the distance between the gas inlet Ma and the gas outlet Mb of the gas meter M. The inner surface of each of the rear ends of the guide grooves 23A and 23B is a semicircular arc surface 23a whose radius is the groove width.

Two second guide grooves 24A and 24B are formed on both left and right sides of the support plate 2, respectively. The second guide grooves 24A, 24B are provided with the first guide grooves 23A, 23B.
Are formed along an arc centered on the center of curvature of each of the arc surfaces 23a, 23a, and have a length corresponding to an angle of approximately 90 °. One end (hereinafter, referred to as an inner end) of each of the second guide grooves 24A, 24B is located immediately behind the first guide grooves 23A, 23B, and the other end (hereinafter, referred to as an outer end) has a curvature of the arc surface 23a. It is located at the same position in the front-rear direction with the center, and is located outside the support plate 2 (left side in FIG. 1) from the center of curvature.

The support plate 2 has a second guide groove 24.
A third guide groove 25A, 25B extending forward from each inner end of A, 24B is formed, respectively. Further, guide surfaces 26A and 26B are formed at respective intersections of the left and right side surfaces and the rear end surface of the support plate 2 respectively. Each of the guide surfaces 26A, 26B is formed in a substantially quarter-arc shape centered on the center of curvature of each of the arc surfaces 23a of the first guide grooves 23A, 23B.

The inflow pipe 3A is formed by bending a metal pipe in a substantially U-shape.
It is 1. Both ends of the gas passage 31 are open to the end face of the inflow side end (the other end) 3a and the end face of the outflow side end (the one end) 3b of the inflow pipe 3A. Gas passage 3
A gas stopper 32 is provided at the center of the inflow pipe 3A in order to open and close 1. Therefore, if this support device A is used, there is no need to separately install a gas stopper, and the labor required for the operation of installing the gas meter M can be reduced by that much. Note that the internal structure of the gas stopper 32 is the same as that of a known gas stopper, and a description thereof will be omitted.

The inflow pipe 3A is arranged so as to straddle one side (the left side in FIG. 1) of the support plate 2 from above with both ends 3a and 3b facing downward. An annular recess 33 is formed on the outer peripheral surface of the outflow end 3b of the inflow pipe 3A. The side edge of the support plate 2 facing the side of the first guide groove 23A is fitted into the annular recess 33 so as to be relatively movable in the front-rear direction and relatively rotatable. Thus, the inflow pipe 3A is connected to the support plate 2 so as to be movable in the front-rear direction, and the inflow end 3a is connected to the outflow end 3b.
Can be rotated in the horizontal direction around the center.

As shown in FIGS. 1B, 4 and 5, a guide projection 34 is formed on the lower surface at the center of the inflow pipe 3A. The guide projection 34 is disposed so as to enter the second guide groove 24A when the inner peripheral surface of the annular recess 33 substantially contacts the arc surface 23a of the first guide groove 23A. Moreover, the guide projection 34 is fitted into the third guide groove 25A so as to be movable in the longitudinal direction. Therefore, when the inflow pipe 3A is rotated about the outflow end 3b while the inner peripheral surface of the annular concave portion 33 is almost in contact with the arc surface 23a, the guide projection 34 is moved to the second guide groove 24.
Move inside A. In addition, since the guide projection 34 enters the second guide groove 24A, the outflow side end 3b is fixed at a position almost in contact with the arc surface 23a.

Further, as shown in FIGS. 1A and 4, the guide projection 34 abuts against both ends of the second guide groove 24A, so that the rotation range of the inflow pipe 3A is substantially 90 degrees.
° is restricted to the range. When the guide projection 34 abuts against the inner end of the second guide groove 24A, the inflow pipe 3A
The inflow side end 3a and the outflow side end 3b are arranged in the front-back direction. The position of the inflow pipe 3A at this time is the closed position. When the guide projection 34 abuts on the outer end of the second guide groove 24A, the inflow side end 3a and the outflow side end 3b are aligned in the left-right direction. The turning position of the inflow pipe 3A at this time is the deployed position.

When the inflow pipe 3A is turned to the closed position, the guide projection 34 is moved from the inner end of the second guide groove 24a to the third position.
It can enter the guide groove 25A, thereby allowing the inflow pipe 3A to move forward. The forward moving range of the inflow pipe 3A is regulated by the guide projection 34 abutting on the front end of the third guide groove 25A. In addition,
Even when the guide projection 34 abuts on the front end of the third guide groove 25A, the outflow side end 3b does not fall out of the first guide groove 23A. Also, the guide projection 34
When the inflow pipe 3A is moved forward until the inflow pipe 3A abuts on the front end of the third guide groove 25A, the first guide groove 23A is formed so that the inflow side end 3a does not abut on the rear surface of the support plate 2. An arc-shaped escape portion 27A into which the inflow-side end portion 3a enters is formed on the rear side surface of the support plate 2 located on an extension of FIG. An escape portion 27B similar to the escape portion 27A is also formed on the rear side surface of the support plate 2 located on an extension of the first guide groove 23B.

As shown in FIGS. 1A and 5, two fixed pieces 35a and 35b are formed in the inflow pipe 3A. The fixing pieces 35a and 35b are arranged so as to be located on both sides of the second guide groove 24A, and the bolts B ₃ and B ₄ are inserted through them. And bolts B ₃ and B ₄
Are screwed into the screw holes 28a, 28b formed in the support plate 2 and tightened, whereby the fixing pieces 35a, 35b are pressed and fixed to the upper surface of the support plate 2, and the inflow pipe 3A is fixed to the support plate 2. It has become. Here, six sets of screw holes 28a and 28b are formed. Two of them
The sets are arranged so as to fix the inflow pipe 3A to the closed position and the position where the guide protrusion 34 abuts on the front end of the third guide groove 25A, respectively.
They are arranged so that they can be fixed at a position rotated by 45 ° from the closed position to the deployed position side and at a position separated from the deployed position by 15 ° intervals. Therefore, in this embodiment, the inflow pipe 3A is
The closed position, the front position moved forward from the closed position, the position rotated 45 ° from the closed position to the deployed position, two positions that separate the extended position from the closed position at 15 ° intervals, and the deployed position in total of 6 It can be fixed in any one of the two positions.

As shown in FIGS. 2 and 3, the inflow pipe 3A
The inflow-side end 3a and the outflow-side end 3b project downward from the support plate 2, and the upstream end 3a that projects downward from the support plate 2 is provided with a joint portion 36, and the downstream end 3
b is provided with a cap nut 37.

The joint 36 has a flexible gas pipe Fa.
Are connected via the connection mechanism 7. This flexible gas pipe Fa is connected to a gas pipe on the main stopper side. In addition,
Since the connection mechanism 7 is well known, its description is omitted. On the other hand, the cap nut 37 is screwed into the gas inlet Ma of the gas meter M as shown in FIG. Then, by tightening the cap nut 37, the connection cylindrical portion Ma is connected and fixed to the downstream end 3b. As a result, the gas meter M
Is supported by the support plate 2 via the inflow pipe 3A,
The gas meter M has an inflow pipe 3 from the flexible gas pipe Fa.
Gas is introduced via A.

Next, regarding the outflow pipe 3B, the outflow pipe 3B is not provided with the gas stopper 32 of the inflow pipe 3A.
As shown in FIG. 7, a protruding portion 38 is formed on the outer peripheral surface of the intermediate portion. In the protruding portion 38, an inspection hole 38a is formed, one end of which is open on the distal end surface of the protruding portion 38 and the other end is open on the inner surface of the gas passage 31. Therefore, by connecting the gas pipe of a pressure gauge (not shown) to the protruding portion 38, the gas pressure can be measured and the gas leak can be inspected. The gas leak test can be performed by opening the gas stopper 32, closing the main valve and all gas appliances in the home, and detecting whether or not the gas pressure decreases after a certain period of time. In addition, the inspection hole 38a is a stopper 3
9 is closed except at the time of inspection.

Another configuration relating to the outflow pipe 3B is as follows.
B is disposed on the other end side (right side in FIG. 1) of the support plate 2, the inflow side end (one end) 3a is disposed on the near side, and the outflow side end (other end) 3b is disposed on the rear side. And a point where the gas outlet Mb of the gas meter M is connected and fixed to the inflow side end 3a, and the flexible gas pipe Fb connected to the domestic gas pipe is connected to the outflow side end 3b. Except for the above, the configuration is the same as that of the inflow pipe 3A. Therefore, regarding another configuration related to the outflow pipe 3B, the inflow pipe 3B
The same components as those of A are denoted by the same reference numerals, and description thereof will be omitted.

In the gas meter supporting apparatus A having the above-described structure, the inflow pipe 3A is rotatable about the outflow end 3b, and the outflow pipe 3B is rotatable about the inflow end 3a. As shown in FIG. 2, the inflow pipe 3A
And the outlet pipe 3B is located at the closed position, and FIGS.
Can be located at the deployed position, as shown in FIG. 9, or at an intermediate position, as shown in FIGS. When the inflow pipe 3A and the outflow pipe 3B are located at the closed positions, the gas meter M and the flexible gas pipes Fa, F
Since b overlaps forward and backward, the overall width can be reduced as compared with the case where the b is located at the developed position. Conversely, when the flexible gas pipes Fa, Fb
And the gas meter M are arranged side by side, so that the front and rear width can be narrowed as compared with the case where the gas meter M is located at the closed position. Furthermore, when it is located at the intermediate position, the front-rear and left-right widths can be made relatively narrow. Thus, by changing the rotation position of the inflow pipe 3A and the outflow pipe 3B,
Since the arrangement of the flexible gas pipes Fa and Fb can be changed, and the width of the front and rear and the left and right of the entire support device A can be changed, even in a narrow space such as a pipe shaft of an apartment, it is possible to cope with the surrounding situation. Therefore, the gas meter M can be easily installed. For example, as shown in FIGS. 9 and 10, when the support plate 2 of the support device A is fixed to the wall W, the joint 36 is rotated by rotating the inflow pipe 3A and the outflow pipe 3B to the intermediate position. The contact with the wall W can be prevented.

In this embodiment, since the inflow pipe 3A and the outflow pipe 3B can be moved forward from the closed position, as shown in FIG. The contact with the screw nut 64 that is screwed can be prevented. Of course, if the support hole 21 is arranged further rearward, the gas meter M can be prevented from contacting the cap nut 64 without moving the inflow pipe 3A and the outflow pipe 3B forward. In this case, when the inflow pipe 3A and the outflow pipe 3B are located at the deployed position, the position between the support of the support plate 2 by the support column 4 and the support of the inflow pipe 3A and the outflow pipe 3B by the support plate 2 is set. Becomes large, the weight of the gas meter M acts on the supporting portions of the support 4 and the support plate 2 as a large moment. For this reason, the support 4 and the support plate 2 may be deformed.

Next, another embodiment of the present invention will be described. In the following embodiment, only the configuration different from the above embodiment will be described, and the same reference numerals will be given to the same configuration as the above embodiment, and the description thereof will be omitted. When the configuration related to the inflow pipe 3A is similar to the configuration related to the outflow pipe 3B, only the configuration related to the inflow pipe 3A will be described.

FIGS. 12 to 15 show a second embodiment of the present invention. In the gas meter support device B of this embodiment, the second guide groove 24A is formed by the circular arc portion 2.
4a and a straight portion 24b. Arc part 24
a is the same as the half including the outer end of the second guide groove 24A in the above embodiment. On the other hand, the straight portion 24b
Extends in the left-right direction, and its outer end is an arc portion 2
4a is continuous with the rear end. The inner end (inner end) of the straight portion 24b (the center side of the support plate 2) is located at substantially the same position as the front end of the third guide groove 25A of the above embodiment.

As a result of the second guide groove 24A being constructed as described above, while the guide projection 34 is in the arc portion 24a, that is, the inflow pipe 3A is moved approximately 45 degrees from the deployed position.
°, the center of the outflow side end 3b is located at substantially the same position as the center of curvature of the arc surface 23a,
The inflow pipe 3A rotates about the outflow end 3b. On the other hand, while the guide projection 34 enters the straight portion 24b, the outflow end 3b moves in the first guide groove 23A in the front-rear direction as the guide projection 34 moves linearly.
As a result, the inflow pipe 3A rotates about the outflow end 3b. Then, when the guide projection 34 abuts on the inner end of the straight portion 24b, the inflow pipe 3A is located at the closed position. However, the closed position of the support device B is the same position as the front position of the support device A.

When the guide projection 34 linearly moves in the right and left direction in the straight portion 24b and reaches the inner end thereof, the inflow pipe 3A reaches the front position. The left end portion is a plane extending left and right, which is also a plane that is in contact with the front inner surface of the escape portion 27A of the above embodiment.

In this supporting device B, the guide projection 34 protrudes downward from the second guide groove 24A, and a nut N is screwed to a tip (lower end) thereof. The inflow pipe 3A is fixed to the support plate 2 by tightening the nut N so that the lower surface at the center of the inflow pipe 3A is brought into press contact with the upper surface of the support plate 2. Therefore, in the support device B, the inflow pipe 3A and the outflow pipe 3B can be rotated to any positions in the range between the closed position and the deployed position. In this supporting device B, the supporting plate 2
Thread holes 28a and 28b are not formed in the inflow pipe 3
A does not have the fixing pieces 35a and 35b.

In the gas meter supporting apparatus B having the above-described structure, the inflow pipe 3A and the outflow pipe 3B can be appropriately adapted to a narrow space by being positioned at the closed position, the deployed position, and the intermediate position. Also, the inflow side end 3a
There is only one closed position in which the inflow pipe 3A and the outflow pipe 3B are arranged forward and backward, and the inflow pipe 3A and the outflow pipe 3B cannot be moved forward from the closed position.
When B rotates toward the closed position, B moves forward accordingly, so that the rear portion of the gas meter M does not contact the cap nut 64.

FIGS. 16 to 21 show a gas meter supporting device C according to a third embodiment of the present invention. In the support device C, the inflow pipe 3A and the outflow pipe 3B with respect to the support
The following configuration is adopted as the coupling and rotation mechanism of the.

That is, a connecting piece 3c extending rightward from the outflow end 3b when the inflow pipe 3A is located at the closed position is formed at the outflow end 3b of the inflow pipe 3A. The connecting piece 3c is arranged so as to be in contact with the lower surface of the support plate 2. The tip portion of the connecting piece 3c is opposed to the second guide groove 24A, in its distal end portion, the fixing bolt B ₅ passing through the second guide groove 24A from above is screwed. Then, by tightening the fixing bolt B _5, coupling piece 3c is fixed to the support plate 2, so that therefore the inflow pipe 3A is fixed to the support plate 2. Of course, the fixing bolt B _5, second guide 24A to are movably fitted in its longitudinal direction, the inlet pipe 3A is rotatable around the outlet side end portion 3b.

The second guide groove 24A has an arc portion 24a and a straight portion 24b, as in the second embodiment. The arc portion 24a is arranged behind the first guide groove 23A, and is almost equally distributed to the left and right with respect to the first guide groove 23A. Then, as shown in FIG. 20, when the bolt B ₅ is located at the right end portion of the arc portion 24a, as the rear portion of the joint portion 36 is positioned at substantially the same position in the side and the front-rear direction after the support plate 2 Has become. Therefore, in this state, when the support plate 2 is fixed to the wall W via the bracket 5, the inflow-side end 3 a does not hit the wall W. On the other hand, as shown in FIG. 21, the bolt B ₅ abuts against the end portion of the left circular arc portions 24a, the inflow pipe 3A is positioned in the deployed position.

[0042] The straight portion 24b extends to the right obliquely forward from the right end of the arc portion 24a, the bolt B ₅ is arcuate portion 2
When moving from the right end of 4a to the lower end of the straight portion 24b, the outflow end 3b moves to the front end of the first guide groove 23A, and the inflow pipe 3A turns around the outflow end 3b to the closed position. Move.

In the supporting device C having the above structure, the outflow end 3b of the inflow pipe 3A and the inflow end 3a of the outflow pipe 3B are provided.
By forming the connection pieces 3c respectively, the second guide groove 24A can be formed on the right side from the first guide groove 23A, and the second guide groove 24B can be formed on the left side from the first guide groove 23B. By forming the second guide grooves 24A and 24B in such a manner, the left and right widths of the support plate 2 could be reduced.

FIGS. 22 to 24 show a fourth embodiment of the present invention. In the gas meter supporting device D of this embodiment, the inflow side end 3a of the inflow pipe 3A is shown.
Is rotatably and airtightly provided on the inner periphery of the connection nut, with the connection nut 8 preventing it from coming off. A tapered female screw portion 81 is formed on the inner peripheral surface of the lower end of the nut 8.
A rigid gas pipe Ga such as an iron gas pipe is screwed and fixed to the tapered female screw portion 81. This gas pipe G
a is erected and fixed on the ground and is connected to the main plug. On the other hand, a rigid gas pipe Gb such as an iron gas pipe is fixed to the outflow side end 3b of the outflow pipe 3B via a nut 8, similarly to the gas pipe Ga. The gas pipe Gb is erected and fixed on the ground and connected to household gas appliances.
The outer ends of the second guide grooves 24A, 24B are the first guide grooves.
It is located behind the guide grooves 23A and 23B, extends toward the near side from the outer ends so as to approach each other, and is arranged such that the inner ends are located beside the first guide grooves 23A and 23B. The third guide grooves 25A, 25B extend forward from the inner ends of the second guide grooves 24A, 24B. Further, a connecting piece 3c is arranged above the support plate 2.

In the support device D of this embodiment,
Since the gas pipes Ga and Ga have rigidity, the inflow pipe 3A
The outflow pipe 3B is supported by the gas pipes Ga and Gb, and the gas meter M is supported by the gas pipes Ga and Gb. Therefore, in this support device D,
