[0001] The present invention relates to an accessory mounting member for mounting an accessory to a gas meter. [Background technology]

[0002] In a gas meter for home use, etc., auxiliary devices such as a communication device for communicating with a management system and a load meter may be attached to the gas meter. In this case, as disclosed in Patent Document 1, there is a gas meter configured such that a meter-side mounting portion is provided on the outer surface thereof and an accessory device is mounted on the meter-side mounting portion of the gas meter. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-298394 (see FIG. 1) Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, it has become necessary to attach a plurality of accessory devices to a gas meter, resulting in a situation where the number of accessory devices to be attached exceeds the number of meter-side attachment portions of the gas meter. In this case, if a large number of meter-side mounting portions are provided on the gas meter in accordance with the number of auxiliary devices, a significant structural change to the gas meter would be required, which is not preferable.

[0005] Unless a meter-side mounting portion is added to the gas meter, accessory devices will have to be mounted on the meter-side mounting portion of the gas meter and other accessory devices will have to be mounted on the gas pipe, etc., so there is room for improvement.

[0006] An object of the present invention is to provide an accessory mounting member that allows an accessory to be mounted on a gas meter without modifying the structure of the gas meter when the accessory is to be mounted on the gas meter. [Means for solving the problem]

[0007] The accessory equipment mounting member of the present invention comprises a first mounting member, a second mounting member, a connecting portion provided on at least one of the first mounting member and the second mounting member for connecting to a meter-side mounting portion provided on a gas meter, and an equipment mounting portion provided on at least one of the first mounting member and the second mounting member for mounting an accessory equipment of the gas meter, and in a planar view, the gas meter is placed in an area surrounded by the first mounting member and the second mounting member, the first mounting member and the second mounting member are connected, and the connecting portion is connected to the meter-side mounting portion.

[0008] According to the present invention, the first and second mounting members of the accessory mounting member surround the periphery of the gas meter. By connecting the connecting portion of the accessory mounting member to the meter-side mounting portion of the gas meter, the weight of the accessory mounting member is supported by the meter-side mounting portion of the gas meter, and the accessory mounting member is attached to the gas meter. In this case, the meter-side mounting portion of the gas meter is an existing part, and there is no need to make any structural changes to the gas meter.

[0009] According to the present invention, the first mounting member and the second mounting member surround the gas meter, making the first mounting member and the second mounting member longer, and therefore there are many portions on the first mounting member and the second mounting member where equipment mounting sections for attaching accessory equipment can be provided. This means that the required number of equipment mounting portions can be provided on one or both of the first mounting member and the second mounting member depending on the number of accessory devices, and the equipment mounting portions can be provided reasonably on one or both of the first mounting member and the second mounting member.

[0010] As described above, according to the present invention, an accessory mounting member has been obtained that can effectively utilize the existing meter-side mounting portion of the gas meter and can mount multiple accessory devices to the gas meter without making any structural changes to the gas meter. When only one equipment mounting portion is provided, the most suitable installation location can be selected from the first mounting member and the second mounting member, resulting in an accessory equipment mounting member with a high degree of freedom in installation of the equipment mounting portion.

[0011] In the present invention, it is preferable that a receiving portion that is placed from above on a protrusion that is provided on the side of the gas meter so as to face outward is provided on at least one of the first mounting member and the second mounting member.

[0012] Some gas meters are constructed with a two-part structure consisting of an upper case and a lower case, with flanges provided on the outer periphery of the upper case and the lower case, and the flanges of the upper case and the lower case are connected with bolts. As a result, the gas meter has a protrusion, like the flanges mentioned above, that is provided on the side of the gas meter and faces outward.

[0013] According to the present invention, by placing the receiving portion of the accessory mounting member on the protruding portion of the gas meter from above, the weight of the accessory mounting member is supported not only by the meter-side mounting portion of the gas meter via the connecting portion of the accessory mounting member, but also by the protruding portion of the gas meter via the receiving portion of the accessory mounting member, thereby improving the stability of the attachment of the accessory mounting member.

[0014] In the present invention, it is preferable that the receiving portion is provided with an opening into which the upwardly facing convex portion provided on the protruding portion fits.

[0015] As mentioned above, when the flange of the upper case and the flange of the lower case are connected by a bolt in a gas meter, the head of the bolt protrudes upward from the flange of the upper case. As a result, some gas meters have a protrusion that faces upward, like the bolts in the flanges mentioned above.

[0016] According to the present invention, when the receiving portion of the accessory mounting member is placed on the protruding portion of the gas meter from above, the convex portion of the protruding portion of the gas meter fits into the opening of the receiving portion of the accessory mounting member, thereby positioning the accessory mounting member in the horizontal direction and making it difficult for the receiving portion of the accessory mounting member to come off the protruding portion of the gas meter. This is advantageous in terms of improving the stability of the attachment of the accessory mounting member.

[0017] In the present invention, it is preferable that the receiving portion be disposed on the opposite side of the gas meter from the connecting portion.

[0018] According to the present invention, when the weight of the accessory mounting member is supported by the connecting portion and receiving portion of the accessory mounting member, the connecting portion and receiving portion of the accessory mounting member are positioned apart from each other across the gas meter, which is advantageous in terms of improving the stability of the attachment of the accessory mounting member.

[0019] In the present invention, it is preferable that the first mounting member is provided with an 11th portion, a 12th portion extending from one horizontal portion of the 11th portion in a direction intersecting the 11th portion, and a 13th portion extending from the other horizontal portion of the 11th portion in the same direction as the 12th portion, and the second mounting member is provided with a 21st portion, a 22nd portion extending from one horizontal portion of the 21st portion in a direction intersecting the 21st portion, and a 23rd portion extending from the other horizontal portion of the 21st portion in the same direction as the 22nd portion, and that the gas meter is arranged in an area surrounded by the 11th portion, the 12th portion, the 13th portion, the 21st portion, the 22nd portion, and the 23rd portion in a planar view, and at least one of the 12th portion and the 22nd portion and the 13th portion and the 23rd portion is connected.

[0020] According to the present invention, the first mounting member of the accessory mounting member is provided with the 11th, 12th and 13th portions, and the second mounting member of the accessory mounting member is provided with the 21st, 22nd and 23rd portions. By connecting at least one of the 12th part of the first mounting member and the 22nd part of the second mounting member, and the 13th part of the first mounting member and the 23rd part of the second mounting member, the first mounting member and the second mounting member of the accessory equipment mounting member surround almost the entire circumference of the gas meter. This has the advantage that the first and second mounting members are provided with a large number of locations where device mounting parts for attaching accessory devices can be provided, which increases the degree of freedom in arranging the device mounting parts, making it easier to install the device mounting parts in desired locations.

[0021] In the present invention, it is preferable that the 12th portion and the 22nd portion overlap, and the 13th portion and the 23rd portion overlap.

[0022] According to the present invention, at least one of the 12th part and the 22nd part of the first mounting member and the 13th part and the 23rd part of the second mounting member are connected in a state where the 12th part of the first mounting member and the 22nd part of the second mounting member overlap, and the 13th part of the first mounting member and the 23rd part of the second mounting member overlap. This allows the first mounting member and the second mounting member to be more firmly connected than in a configuration in which the end of the 12th part (13th part) of the first mounting member and the end of the 22nd part (23rd part) of the second mounting member are connected in a butted state, which is advantageous in terms of improving the stability of the mounting of the accessory equipment mounting member.

[0023] In the present invention, it is preferable that a spacing change section is provided that changes the overlap range between the 12th portion and the 22nd portion and the overlap range between the 13th portion and the 23rd portion, thereby changing the spacing between the first mounting member and the second mounting member when the first mounting member and the second mounting member are connected.

[0024] According to the present invention, when the 12th part (13th part) of the first mounting member and the 22nd part (23rd part) of the second mounting member are connected in an overlapping state, the spacing between the first mounting member and the second mounting member can be changed by changing the overlapping range between the 12th part (13th part) of the first mounting member and the 22nd part (23rd part) of the second mounting member using the spacing change section. This allows the distance between the first mounting member and the second mounting member to be set to an appropriate distance depending on the size of the gas meter and the conditions around the gas meter, increasing the degree of freedom in attaching the accessory equipment mounting member to the gas meter, making it easier to attach the accessory equipment mounting member to the gas meter.

[0025] In the present invention, it is preferable that a plurality of the device mounting portions are provided.

[0026] According to the present invention, by providing a plurality of equipment mounting portions on one or both of the first mounting member and the second mounting member, it is advantageous in that a plurality of accessory devices can be mounted on the accessory device mounting member.

[0027] In the present invention, it is preferable that the meter-side mounting portion is provided with a screw hole for connecting the connecting portion.

[0028] According to the present invention, the connecting portion of the accessory mounting member can be easily connected to the meter-side mounting portion of the gas meter with a bolt, which makes it easy to attach the accessory mounting member to the gas meter.

A number of connecting holes 23b (corresponding to the spacing-changing portions) are provided in the thirteenth portion 23 of the second mounting member 2 along the left-right direction.

[0061] The overlapping range between the 12th part 12 of the first mounting member 1 and the 21st part 21 of the second mounting member 2 can be changed by changing which connecting hole 12b of the first mounting member 1 (the 12th part 12) and which connecting hole 22a of the second mounting member 2 (the 22nd part 22) the bolt 26 is attached to, thereby connecting the 12th part 12 of the first mounting member 1 and the 21st part 21 of the second mounting member 2.

[0062] Depending on which connecting hole 23b of the second mounting member 2 (part 23) and which connecting hole 13a of the first mounting member 1 (part 13) the bolt 26 is attached to, the overlapping range between part 13 of the first mounting member 1 and part 23 of the second mounting member 2 can be changed, thereby connecting part 13 of the first mounting member 1 and part 23 of the second mounting member 2.

[0063] With the above configuration, it is possible to change the distance between the first mounting member 1 and the second mounting member 2 in a state in which the first mounting member 1 and the second mounting member 2 are connected. In the 12th part 12 of the first mounting member 1, a long hole (not shown) (corresponding to the spacing change portion) extending in the left-right direction may be provided in place of the connecting hole 12b, and in the 23rd part 23 of the second mounting member 2, a long hole (not shown) (corresponding to the spacing change portion) extending in the left-right direction may be provided in place of the connecting hole 23b.

[0064] An opening 17a may be provided in the receiving portion 17. In this way, when the receiving portion 17 is placed on the flange portion 4a of the gas meter 3 (upper case 4) from above, the head of the bolt 6 on the flange portion 4a of the gas meter 3 (upper case 4) can be inserted into the opening 17a of the receiving portion 17.

[0065] (Second Alternative Embodiment of the Invention) The accessory mounting member 30 may be configured to include a first mounting member 1 and a second mounting member 2 as described below.

[0067] A pair of long connecting bolts 29 are provided in the left-right direction at the front and rear of the base plate 28. A thin, plate-like anti-slip member 32 made of rubber or synthetic resin is attached to the base plate 28 between the connecting bolts 29. The connecting portion 31 is formed by bending a plate material into a crank shape, and is attached to the front of the base plate 28.

[0068] The second mounting member 2 has a base plate 33, an anti-slip member 32, a nut 34, etc. The base plate 33 is formed by bending a plate material into a channel shape, and screw holes 33a (corresponding to device mounting portions) with female threads are provided in the front and rear of the base plate 33, and a pair of nuts 34 are connected to the right side of the base plate 33. The anti-slip member 32 is attached to the portion of the base plate 33 between the nuts 34.

[0069] In the first mounting member 1 and second mounting member 2 as described above, the gas meter 3 is placed between the first mounting member 1 and the second mounting member 2 (the area surrounded by the base portions 28, 33 and the connecting bolt 29), and the connecting bolt 29 of the first mounting member 1 is inserted into the nut 34 of the second mounting member 2 (base portion 33).

[0070] The connecting bolts 29 are tightened so that the anti-slip members 32 of the first mounting member 1 and the anti-slip members 32 of the second mounting member 2 are pressed against the right and left parts of the gas meter 3 (lower case 5) from the left and right directions. The connecting portion 31 of the first mounting member 1 is connected with the connecting plate 24 connected to the meter-side mounting portion 15 of the gas meter 3 by the bolts 27.
