In the conventional gas meter support device, the fixing member supports the entire weight of the holding member, the primary side connection pipe, the secondary side connection pipe, and the gas meter. However, since the fixing member is formed of a thin plate material, a feeling of insufficient strength cannot be denied, and when an external force acts on the connecting pipe or the gas meter, the fixing member is deformed and the gas meter to be held horizontally is inclined. There was a risk.
In addition, although sufficient strength can be obtained by increasing the thickness of the metal plate constituting the fixing member, the weight of the entire support device of the gas meter becomes excessive, and the work of installing the gas meter is very difficult. Another problem arises that is difficult to do.

The present invention has been made to solve the above-described problem. A primary gas pipe made of a flexible gas pipe is connected to the upstream end, and a gas meter is introduced to the downstream end with the axis line directed in the vertical direction. The primary side connecting pipe to which the port is connected, the outlet port of the gas meter is connected to the upstream end with the axis line directed in the vertical direction, and the secondary side gas pipe consisting of a flexible gas pipe is connected to the downstream end. And the downstream end of the primary side connection pipe and the upstream end of the secondary side connection pipe are separated from each other by a predetermined distance in the horizontal direction. In a gas meter support device having a holding member that holds in a closed state, the support member and the upstream end of the primary connection pipe and the downstream end of the secondary connection pipe are fixed to the support member And a fixing means for further comprising To have.
In this case, the fixing means is formed separately from the primary side fixing means for fixing the upstream end portion of the primary side connecting pipe to the support member, and the primary side fixing means, and is downstream of the secondary side connecting pipe. Secondary side fixing means for fixing a side end portion to the support member, and at least one of the primary side fixing means and the secondary side fixing means is the primary side connecting pipe with respect to the support member. It is desirable that the position can be adjusted in the separating direction between the downstream end of the secondary connection pipe and the upstream end of the secondary connection pipe.
Auxiliary support means fixed to the support member is further provided. The auxiliary support means fixes the upstream end of the primary connection pipe and the downstream end of the secondary connection pipe to the support member. In doing so, it is desirable that a mounting portion on which the holding member is mounted horizontally is provided.
The support member is disposed such that a longitudinal direction thereof is oriented in a horizontal direction that is the same as a separation direction between a downstream end portion of the primary side connection pipe and an upstream end portion of the secondary side connection pipe. desirable.
A primary temporary fixing member that temporarily fixes the upstream end of the primary connection pipe to the support member, and a secondary temporary fixing member that temporarily fixes the downstream end of the secondary connection pipe to the support member. It is desirable to further include.
As a temporary fixing tool used as a primary temporary fixing member or a secondary temporary fixing member of a gas meter support device, it engages with one end portion so as not to move downward in a range from the upper surface portion to the rear surface portion of the support member. It has a first engaging part, and moves to the upstream end of the primary side connecting pipe or the downstream side end of the secondary side connecting pipe at the other end downward and in the horizontal direction away from the front part of the support member. A second engaging portion that is impossiblely engaged, wherein the first engaging portion is engaged with the support member, and the second engaging portion is an upstream end portion or a secondary portion of the primary side connecting pipe. In a state where the downstream end portion of the side connection pipe is engaged, it is desirable that the outer peripheral surface of the connection pipe is in contact with the support member. The first engagement portion includes a placement portion that is placed on the upper surface of the support member, and a locking arm portion that extends downward from one end portion of the placement portion and contacts the back portion of the support member. And the second engagement portion is formed on the outer peripheral surface of the fitted connection tube, and the upstream end portion of the primary connection tube or the downstream end portion of the secondary connection tube is fitted. It is desirable to have a fitting portion on which an annular surface facing downward is placed.

According to the gas meter support device of the present invention having the above-described characteristic configuration, since the primary side and secondary side connection pipes are fixed to the support member by the fixing means, the support strength can be improved. Therefore, even if the holding member is made of a thin metal plate, the deformation can be prevented.
Further, according to the temporary fixing tool of the present invention, the primary side and secondary side connection pipes are temporarily fixed to the support member at the time of fixing the primary side connection pipe and the secondary side connection pipe to the support member. The person does not need to support the primary side and secondary side connection pipes by hand during the fixing operation. Therefore, the primary side and secondary side connection pipes can be fixed easily.

The best mode for carrying out the present invention will be described below with reference to the drawings.
1 to 3 show a first embodiment of a gas meter support device according to the present invention. The gas meter support device A of this embodiment is configured such that a gas meter (not shown) is attached to a vertical side wall (support member) W of a house, and includes a fixing member (auxiliary support means) 1 and a holding member 2. The primary side connecting pipe 3, the secondary side connecting pipe 6, and the first and second fixing plates 9A and 9B are the main constituent elements.

  The fixing member 1 is made of a metal plate, and is formed integrally with a fixed plate portion 1a extending vertically and an upper end portion of the fixed plate portion 1a, and forward from the upper end portion of the fixed plate portion 1a. It has the mounting board part (mounting part) 1b extended horizontally. The fixed plate portion 1 a is pressed and fixed to the side wall W by screws 11. Therefore, the fixing member 1 can be fixed at an arbitrary position on the side wall W. In addition, since the screw 1 is inserted into the elongated hole 1c formed in the fixed plate portion 1a and extending in the vertical direction, the fixing member 1 adjusts the position of the fixed plate portion 1a in the vertical direction and the horizontal position of the mounting plate portion 1b. Adjustment is possible. A reinforcing plate 1d extending downward is formed on one side of the mounting plate 1b in the left-right direction. Reinforcement for the downward force of the mounting plate portion 1b is performed by the side surface facing the rear of the reinforcing plate portion 1d striking the fixed plate portion 1.

  The holding member 2 is made of a metal flat plate and is disposed horizontally. The front end surface of the holding member 2 is formed with first and second mounting recesses 2a and 2b that are spaced apart in the left-right direction. The center-to-center distance between the first and second mounting recesses 2a and 2b is set to be the same as the center-to-center distance between the inlet for introducing gas into the gas meter and the outlet for discharging gas from the gas meter. The holding member 2 is mounted on the mounting plate portion 1b of the fixing member 1, and is mounted by tightening a bolt 12 that passes through the holding member 2 and the mounting plate portion 1b and a nut 13 that is screwed to the bolt 12. It is pressed and fixed to the mounting plate portion 1b. The bolt 12 is inserted into a long hole 1e formed in the mounting plate portion 1b and extending in the front-rear direction, so that the position of the holding member 2 can be adjusted in the front-rear direction.

  The primary side connection pipe 3 has a main pipe 4 and a sub pipe 5. The main pipe 4 is formed in an inverted “U” shape. As a result, the upstream end 4a and the downstream end 4b of the main pipe 4 are parallel to each other, and the axis is directed in the vertical direction. The upper end portion of the secondary pipe 5 is screwed and fixed to the upstream end portion 4a. A flexible gas pipe G1, which is a primary gas pipe, is connected to the lower end of the sub pipe 5 via a joint C1. As will be apparent from the fact that the sub pipe 5 is fixed to the main pipe 4, the main pipe 4 and the sub pipe 5 may be formed integrally with each other as in the embodiments described later. Alternatively, the secondary pipe 5 and the joint C1 may be omitted, and the primary gas pipe G1 may be directly connected to the upstream end 4a of the main pipe (primary connection pipe) 4.

  An intermediate portion in the vertical direction of the downstream end portion 4 b of the main pipe 4 is rotatably inserted into the first mounting recess 2 a of the holding member 2. By rotating the main pipe 4 (primary side connecting pipe 3) around the downstream end 4b, the position of the upstream end 4a in the horizontal direction can be adjusted. The downstream end 4b is provided with a fixed arm 4c that is in contact with the upper surface of the holding member 2. The fixing arm 4c is fixed to the holding member 2 by tightening the bolt 14 passing through the fixing arm 4c and the holding member 2 and the nut 15 screwed to the bolt 14 and the main pipe 4 is fixed to the holding member 2 by extension. Has been. The bolt 14 is inserted into an arcuate guide hole 2c formed in the holding member 2 so as to be movable in the longitudinal direction. Therefore, the downstream end 4b can be rotated about its axis, and thereby the position of the upstream end 4a in the horizontal direction can be adjusted as appropriate. A connecting nut 4d is rotatably provided at the lowermost end portion located below the holding member 2 of the downstream end portion 4b. By screwing the connecting port 4d into the connecting nut 4d and tightening the connecting nut 4d, the connecting port is connected and fixed to the main pipe 4, that is, the downstream end 4b of the primary connecting tube 3. ing. Therefore, the gas supplied from the flexible gas pipe G1 passes through the joint C1 and the primary side connection pipe 3, and is introduced into the gas meter from the introduction port.

  A handle 4e is rotatably provided at the upper end of the main pipe 4. The handle 4e is for turning a valve body (not shown) provided in the main pipe 4. When the handle 4e is turned to the closed position, the valve body closes the inside of the main pipe 4. Block gas flow. On the other hand, when the handle 4e is turned to the open position, the valve element opens the inside of the main pipe 4 to allow gas flow.

  Similar to the primary side connection pipe 3, the secondary side connection pipe 6 has a main pipe 7 and a secondary pipe 8. The main pipe 7 has an inverted “U” shape like the main pipe 4 of the primary side connecting pipe 3, and the upstream end 7 a and the downstream end 7 b are parallel to each other with the axis line in the vertical direction. ing. An intermediate portion in the up-down direction of the upstream end portion 7a is rotatably inserted into the second mounting recess 2b. Therefore, the main pipe 7 can be rotated around the axis of the upstream end 7a, and thereby the horizontal position of the downstream end 7b can be adjusted. A fixed arm 7c that is in contact with the upper surface of the holding member 2 is provided at the upstream end 7a. A bolt 16 that passes through the fixed arm 7c and the holding member 2 and a nut 17 that is screwed to the bolt 16 are provided. The fixing arm portion 7c is fixed to the holding member 2, and as a result, the main pipe 7 (secondary side connecting pipe 4) is fixed to the holding member 2. The bolt 16 is inserted into an arcuate guide hole 2d formed in the holding member 2 so as to be movable in the longitudinal direction. Therefore, the main pipe 7 can be rotated around its upstream end 7a, and thereby the position of the downstream end 7b can be adjusted in the horizontal direction. A connecting nut 7d is rotatably provided at the lowermost end portion located below the holding member 2 of the upstream end portion 7a. The lead-out port is connected and fixed to the upstream end 7a of the main pipe 7 by screwing the lead-out port formed on the upper surface portion of the gas meter to the connection nut 7d and tightening the connection nut 4d. At this time, the distance between the downstream end 4b of the primary connection pipe 3 and the upstream end 7a of the secondary connection pipe 6 is made equal to the distance between the inlet and the outlet by the holding member 2. Since it is maintained, the connection of the inlet and the outlet can be easily performed.

  The upper end portion of the sub pipe 8 is screwed and fixed to the downstream end portion 7 b of the main pipe 7. The secondary side gas pipe G2 which consists of a flexible gas pipe is connected to the lower end part of the sub pipe 8 via the coupling C2. Therefore, the gas led out from the outlet through the gas meter flows into the secondary gas pipe G2 via the secondary side connecting pipe 6 and the joint C2. And it supplies to a household gas appliance (not shown), for example from the secondary side gas pipe G2. As is clear from the fact that the sub pipe 8 is fixed to the main pipe 7, the main pipe 7 and the sub pipe 8 may be formed integrally with each other as in an embodiment described later. Alternatively, the secondary pipe 8 and the joint C2 may be omitted, and the secondary gas pipe G2 may be directly connected to the downstream end 7b of the main pipe 7 (secondary connection pipe 6).

  The first fixing plate (primary side fixing means) 9A is for fixing the sub pipe 5 to the side wall W, thereby fixing the primary side connecting pipe 3 to the side wall W, and molding a metal plate or resin. It is formed by. Flat plate portions 9a and 9b are formed at both ends of the first fixed plate 9A, and a substantially semicircular pressing portion 9c is formed at the center portion. A large-diameter portion 5a having a circular cross section of the sub pipe 5 is inserted through the pressing portion 9c. The pressing portion 9c presses and fixes the large-diameter portion 5a to the side wall W by tightening the screws 18 and 18 screwed into the side wall W through the flat plate portions 9a and 9b. As a result, the secondary pipe 5 is fixed to the side wall W with its axis line oriented in the vertical direction, and consequently the upstream end 4a of the primary connection pipe 3 is fixed to the side wall W with its axis line oriented in the vertical direction. Has been. In order to enable pressing and fixing to the side wall W of the sub-pipe 5, the large-diameter portion 5a has an outer diameter equal to or greater than that of other members aligned in the vertical direction, and the large-diameter portion When the upstream end 4a side of the primary side connecting pipe 3 is brought close to the side wall W with the axis of 5a directed in the vertical direction, the large diameter portion 5a is brought into the side wall W at the same time as other members or earlier than the other members. It comes to contact.

  The second fixing plate (secondary fixing means) 9B is configured in the same manner as the first fixing plate 9A, and the first fixing plate 9A fixes the large-diameter portion 5a of the sub pipe 5 to the side wall W. Similarly, the large-diameter portion 8a of the sub pipe 8 is fixed to the side wall W.

  In the gas meter support device A configured as described above, the gas meter and the primary side and secondary side connection pipes 3 and 6 are supported not only by the fixing member 1 via the holding member 2 but also the primary side and secondary side connection. Since the pipes 3 and 6 are directly supported by the side wall W by being pressed and fixed to the side wall W by the first and second fixing plates 9A and 9B, the gas meter of the support device A and the primary side and secondary side connection pipes 3 are supported. , 6 can be improved. Therefore, when an external force acts on the gas meter or the primary side connection pipe 3 or the secondary side connection pipe 6, the external force is received by the primary side connection pipe 3 or the secondary side connection pipe 6 and acts on the holding member 2 and the fixing member 1. There is little to do. Therefore, it is possible to prevent a situation in which the fixing member 1 and the holding member 2 are deformed. Moreover, since the support strength by the primary side and secondary side connection pipes 3 and 6 is large, the fixing member 1 can be omitted. When the fixing member 1 is provided, when the primary side and secondary side connection pipes 3 and 6 are fixed to the side wall W, the holding member 2 to which the primary side and secondary side connection pipes 3 and 6 are attached is placed. The fixing member 1 may be used only for placement on the plate portion 1b. Thereby, at the time of fixing work of the primary side and secondary side connection pipes 3 and 6, an operator can be released from heavy labor of supporting the gas meter and the connection pipes 3 and 6 by hand.

  Next, another embodiment of the gas meter support device according to the present invention will be described. In the following embodiment, only the configuration different from the above-described embodiment will be described, and the same components are denoted by the same reference numerals and description thereof will be omitted.

  4 to 6 show a second embodiment of a gas meter support device according to the present invention. In the support device B of this embodiment, two channel steels 20 having a substantially square cross section are used as support members that replace the side walls W. Each channel steel 20 is disposed such that its longitudinal direction is in the left-right direction and the front surfaces thereof are located on the same vertical plane. An open portion 20 a extending along the longitudinal direction is formed at the center of the front surface of the channel steel 20. Protruding pieces 20b and 20b projecting inward of the channel steel 20 are formed on the front surface of the channel steel 20 facing the upper and lower sides of the open portion 20a. Two channel steels 20 are used in this embodiment, but one or three or more may be used.

  Further, in this support device B, sub pipes 5A and 8A are used in place of the sub pipes 5 and 8, respectively. That is, the primary side connecting pipe 3 is composed of the main pipe 4 and the sub pipe 5A, and the secondary side connecting pipe 6 is composed of the main pipe 7 and the sub pipe 8A. Small-diameter portions 5b and 8b having smaller diameters than both ends are formed at the center in the vertical direction of each of the sub-tubes 5A and 8A. The small diameter portions 5b and 8b of the sub-tubes 5A and 8A are fixed by first and second fixing plates (first and second fixing means) 9C and 9D instead of the first and second fixing plates 9A and 9B. Yes. In the first and second fixing plates 9C and 9D, fitting pieces 9d are formed on the outer ends of the flat plate portions 9a and 9b so as to protrude on the opposite side to the protruding side of the pressing portion 9c. The fitting piece 9d is inserted into the open portion 20a of the channel steel 20 so as not to move in the vertical direction and to be movable in the left-right direction. Thereby, the position of the first and second fixing plates 9C and 9D can be adjusted in the longitudinal direction (left-right direction) of the channel steel 20. A nut member 21 is disposed inside the channel steel 20 so as to be movable in the left-right direction. Bolts 22 penetrating through the flat plate portions 9a and 9b of the first fixing plate 9C are screwed to the nut member 21, respectively. Therefore, when the bolt 22 is tightened, the nut member 21 is pressed against the protruding pieces 20b and 20b, and the small diameter portions 5b and 8b of the sub-tubes 5A and 8A are pressed against the front surface of the channel steel 20 by the pressing portion 9c, The primary side and secondary side connection pipes 3 and 6 are pressed and fixed to the channel steel 20. In this embodiment, the upper and lower end portions of the small diameter portions 5b, 8b of the secondary tubes 5A, 8A are pressed and fixed to the two channel steels 20, 20, respectively, so that the primary side and secondary side connection tubes 3 , 6 are firmly fixed to the channel steels 20, 20, so that the fixing member 1 is not used.

  Further, in the support device B, a primary side temporary fixing member (temporary fixing portion) 23A and a secondary side temporary fixing member (temporary fixing tool) 23B are used. The primary side and secondary side temporary fixing tools 23A, 23B hold the primary side and secondary side connection pipes 3, 6 when fixing the primary side and secondary side connection pipes 3, 6 to the channel steel 20, Accordingly, the operator can be freed from the heavy labor of supporting the gas meter and the connecting pipes 3 and 6 by hand when the primary and secondary connecting pipes 3 and 6 are fixed to the channel steel 20. As shown in FIG. 8, the primary-side temporary fixing member 23A is made of a metal wire, and has a fitting portion 23a having a circumference larger than a semicircle and a pair extending in parallel to each other from the fitting portion 23a. Receiving portions 23b, 23b, and locking arm portions 23c, 23c extending in a direction orthogonal to the tip portions of the receiving portions 23b, 23b. The fitting portion 23a constitutes a second engaging portion, and the receiving portion 23b and the locking arm portion 23c constitute a first engaging portion. Since the secondary temporary fixing member 23B is formed in the same manner as the primary temporary fixing member 23A, the description thereof is omitted.

  The small diameter portion 5b is fitted to the fitting portion 23a of the primary side temporary fixing member 23A. A lower end surface (supported surface) 4f of the upstream end portion 4a of the main pipe 4 is placed on the upper surface of the fitting portion 23a. Of course, in order to be able to place the lower end surface 4f on the fitting portion 23a in a state where the small diameter portion 5b is fitted to the fitting portion 23a, the outer diameter of the upstream end portion 4a having the lower end surface 4f. Is larger than the outer diameter of the small diameter portion 5b. On the other hand, the receiving portion 23 b is placed on the upper surface of the channel steel 20, and the locking arm portion 21 c extends downward along the rear surface of the channel steel 20. Here, in a state where the receiving portion 21 b is placed on the channel steel 20, the small diameter portion 5 b is substantially in contact with the front surface of the channel steel 20, and the locking arm portion 21 c is substantially in contact with the back surface of the channel steel 20. Therefore, the small diameter part 5b and the latching arm part 23c exhibit the situation where the channel steel 20 was clamped from front and back. As a result, the primary side temporary fixing member 23 </ b> A is securely locked to the channel steel 20 and holds the primary side connection pipe 3.

  In the secondary temporary fixing member 23B, the small diameter portion 8b is inserted into the fitting portion 23a, and the lower end surface (supported surface) 7e of the downstream end portion 7b of the main pipe 7 is placed on the fitting portion 23a. The primary side fixing member 23 </ b> A is the same as the primary side temporary fixing member 23 </ b> A except for the points described above.

  In the gas meter support device B having the above-described configuration, the primary side temporary fixing member 23A holds the primary side connection pipe 3 during the fixing operation of the primary side and secondary side connection pipes 3 and 6 to the channel steels 20 and 20. Since the secondary side temporary fixing member 23B holds the secondary side connecting pipe 6, it is not necessary to support the primary side and secondary side connecting pipes 3 and 6 by hand. Therefore, it is possible to easily fix the primary side and secondary side connecting pipes 3 and 6 to the channel steel 20.

  FIG. 9 shows another embodiment of the primary side temporary fixing member and the secondary side temporary fixing member. The primary side temporary fixing member 23C (same for the secondary side temporary fixing member 23D) of this embodiment is made of a metal or resin plate. As a result, the fitting portion 23a is formed as a ring, and the receiving portion 23b and the locking arm portion 23c are formed in a flat plate shape.
