Description

  The present invention relates to a gas meter fixing tool for fixing a gas meter to a wall surface, and a gas meter fixing method for fixing the gas meter to a wall surface using the gas meter fixing tool.

As a conventional gas meter fixture for fixing a gas meter to a wall surface, a gas meter fixture 100 as shown in FIGS. 6 and 7 is known (see, for example, Patent Document 1). Although details will be described later, FIG. 6 is a schematic perspective view of the new gas meter fixture 100a, and FIG. 7 is a schematic perspective view of the old gas meter fixture 100b.
This type of gas meter fixture 100 includes a spacer member 20 fixed to a wall surface 1 such as a house, and an adapter member 30 that can be fixed to the spacer member 20 and fix the gas meter 10 (see FIG. 1).
The spacer member 20 includes a wall surface fixing piece 21 formed on the wall surface 1 and formed with a screw insertion hole 22 fixed to the screw portion with a screw S, and a spacer side fixing piece arranged at a predetermined interval from the wall surface 1. 25. On the other hand, the adapter member 30 has an adapter side fixing piece 35 fixed to the spacer side fixing piece 25 and a gas meter fixing piece 31 in which a support hole 32 for fixing the gas meter 10 is formed.
Further, the adapter side fixing piece 35 is formed with a pair of adapter side engaging holes 36 and adapter side screw insertion holes 37 symmetrically, and the spacer side fixing piece 25 has adapter side engaging holes 36 and 36. Corresponding to the adapter side screw insertion hole 37, a pair of spacer side engagement hooks 26 and a spacer side female thread portion 27 are formed symmetrically. Then, in a state where the adapter side engagement hole 36 is engaged with the spacer side engagement hook 26 and the adapter member 30 is hooked on the spacer member 20, the adapter side screw insertion hole 37 is screwed into the spacer side female thread portion 27. The adapter member 20 can be fixed to the spacer member 30 by fixing by the above.

In addition, a gas meter fixing tool (hereinafter referred to as “new gas meter fixing tool”) 100a (see FIG. 6) for fixing the new gas meter 10a that has been developed and spread in recent years is a gas meter for fixing the old gas meter 10b. Compared with the fixture (hereinafter referred to as “old gas meter fixture”) 100b (see FIG. 7), it is a small-sized one with a particularly small height in order to reduce the cost and space. ing. Specifically, the new-type gas meter fixture 100a and the old-type gas meter fixture 100b include an adapter-side fixing interval (spacer in the spacer member 20) that is an interval of the adapter-side screw insertion hole 37 with respect to the adapter-side engagement hole 36 in the adapter member 30. As for the spacer-side fixing interval which is the interval of the spacer-side female thread portion 27 with respect to the side engaging hook 26), the interval Ha of the new gas meter fixture 100a is smaller than the interval Hb of the old gas meter fixture 100b. .
In order to distinguish between the new gas meter fixture 100a and the old gas meter fixture 100b, “a” is added to the end of the numerals indicating the main parts corresponding to each other, and in the case of the old model. May be indicated with “b”.

  Further, such a small new gas meter fixture 100a is reinforced such that the thickness of the plate material constituting each member is slightly increased, and sufficient rigidity and strength are realized.

Japanese Patent Laid-Open No. 10-253419

When replacing an old gas meter with a new gas meter, the dimensions of the new gas meter fixture and the old gas meter fixture are particularly different in the height direction as described above. The whole was exchanged.
Then, when the gas meter fixture is exchanged from the new type to the old type in this way, a female thread portion for fixing the new type spacer to the wall surface is newly formed in order to exchange the spacer member fixed to the wall surface from the old type to the new type. There arises a problem that a need arises and a female screw portion for attaching the old gas meter fixing tool remains on the wall surface, which impairs the appearance of the plane.

Further, as a method of replacing the old gas meter with the new gas meter without forming a new female thread portion on the wall surface as described above, as shown in FIG. 2 (a), the old gas meter fixture already fixed to the wall surface The spacer member 20b (hereinafter referred to as “old spacer member”) 20b is used as it is, and the adapter member (hereinafter referred to as “new adapter member”) 30a of the new gas meter fixture 100a is used as the old spacer member 20b. A gas meter fixing method such as fixing the gas can be considered.
However, in such a gas meter fixing method, as shown in FIG. 2 (b), the adapter side engagement hole 36a of the new type adapter member 30a is engaged with the spacer side engagement hook 26b of the old type spacer member 20b, In a state where the new type adapter member 30a is hooked on the old type spacer member 20b, the position of the spacer side female screw portion 27b of the old type spacer member 20b does not coincide with the position of the adapter side screw insertion hole 37a of the new type adapter member 30a. It will be in the state exposed below the lower end part of the adapter side fixing piece 35a. Therefore, in this fixing method, the adapter-side screw insertion hole 37a cannot be directly screw-fixed to the spacer-side female thread portion 27b. Therefore, it is necessary to perform fixing different from screw fixing. The following first or second fixing methods are conceivable.

First, in the first fixing method, in the spacer side fixing piece of the old spacer member already fixed to the wall surface, a new spacer side female thread portion is provided at a position corresponding to the adapter side screw insertion hole formed in the new adapter member. With the new adapter member hooked to the old spacer member, the adapter side screw insertion hole of the new adapter member is screwed to the newly formed spacer side female thread part on the new spacer member. This is a method of fixing the adapter member to the old spacer member.
However, in the first fixing method, an operation using an electric screwdriver or the like for newly forming a spacer-side female thread portion on the old spacer member is necessary, and the operation becomes complicated.

Next, in the second fixing method, the spacer-side fixing piece and the adapter-side fixing piece are laterally moved by a fastener (clamp) while the new adapter member is hooked on the old spacer member already fixed to the wall surface. In this method, the new adapter member is fixed to the old spacer member.
However, in this second fixing method, a relatively expensive fastener is required, and the fastener is arranged in a state of protruding to the side of the old spacer. In addition, there is a problem that the merit of saving space is impaired.

  The present invention has been made in view of the above problems, and its purpose is to fix an old gas meter without forming a new female screw portion on a wall surface when the old gas meter is replaced with a new gas meter. Low cost and space saving when the adapter-side fixing interval is smaller than the spacer-side fixing interval because the new adapter member for fixing the new gas meter is attached to the old spacer member already fixed to the wall surface. It is in the point which implement | achieves the gas meter fixing tool and the gas meter fixing method which do not impair the merit of this as much as possible and do not require a complicated operation.

In order to achieve the above object, a gas meter fixing method according to the present invention includes a spacer member having a spacer-side fixing piece fixed to a wall surface and arranged at a predetermined interval from the wall surface, and the spacer-side fixing piece. The adapter side fixing piece has an adapter member for fixing a pipe joint to which a gas meter is connected and has an adapter side engagement hole and an adapter side screw insertion hole formed in the adapter side fixing piece. A gas meter fixing in which a spacer side engaging hook for engaging the adapter side engaging hole with the spacer side fixing piece and a spacer side female thread portion for fixing the adapter side screw insertion hole are formed. Using tools,
A fitting of the gas meter is fixed to the adapter member fixed in a state where the adapter side engaging hole is engaged with the spacer side engaging hook and hooked to the spacer member, and the gas meter is attached to the wall surface. A gas meter fixing method for fixing, wherein the first characteristic configuration is that an adapter side fixing interval which is an interval of the adapter side screw insertion hole with respect to the adapter side engagement hole in the adapter member is the spacer side in the spacer member. When it is smaller than the spacer-side fixing interval, which is the interval of the spacer-side female thread portion with respect to the engagement hook,
A support-side fixing piece formed with a support-side screw insertion hole that is fixed to the spacer-side female screw portion, and a hook on the spacer member in a state where the support-side screw insertion hole is screwed to the spacer-side female screw portion. Using a support member consisting of a support side locking piece locked to the adapter side screw insertion hole of the stopped adapter member,
With the adapter member hooked to the spacer member, the support-side screw insertion hole is screwed to the spacer-side female screw portion and the support-side locking piece is locked to the adapter-side screw insertion hole. Then, the support member is fixed to the spacer member, and the adapter member is fixed to the spacer member.

In addition, a gas meter fixture according to the present invention for achieving the above object is a gas meter fixture used in the above-described gas meter fixing method according to the present invention, and the characteristic configuration thereof is the adapter side member in the adapter member. The adapter-side fixing interval that is the interval between the spacer-side female screw portions with respect to the joint hole is smaller than the spacer-side fixing interval that is the interval between the spacer-side female screw portions with respect to the spacer-side engaging hook in the spacer member,
A support-side fixing piece formed with a support-side screw insertion hole that is fixed to the spacer-side female screw portion, and a hook on the spacer member in a state where the support-side screw insertion hole is screwed to the spacer-side female screw portion. A support member comprising a support-side locking piece that is locked to the adapter-side screw insertion hole of the stopped adapter member;
With the adapter member hooked to the spacer member, the support-side screw insertion hole is screwed to the spacer-side female screw portion and the support-side locking piece is locked to the adapter-side screw insertion hole. The support member is fixed to the spacer member, and the adapter member is fixed to the spacer member.

  In this specification, in order to simplify the explanation, when replacing the old gas meter with the new gas meter, the relatively small new adapter member is fixed to the relatively large old spacer member already fixed to the wall surface. Therefore, assuming that the adapter-side fixing interval is smaller than the spacer-side fixing interval, “new type” is used at the beginning of the adapter member and gas meter fixture on the side that prescribes the adapter-side fixing interval on the small side. The "older type" is added to the beginning of the spacer member and gas meter fixture on the side that prescribes the spacer-side fixing interval on the larger side, and these are distinguished and called.

  According to the gas meter fixing method and the gas meter fixture according to the present invention, the adapter-side fixing interval in the new adapter member is smaller than the spacer-side fixing interval in the old spacer member, and the new adapter member is hung on the old spacer member. Even when the spacer side female screw portion is in a state where it is exposed to the lower side of the lower end portion of the adapter side fixing piece without matching the position of the adapter side screw insertion hole, In the gas meter fixture composed of the old spacer member and the new adapter member as described above, it is composed of the support-side fixing piece and the support-side locking piece as described above, and the spacer-side female thread portion of the old spacer member is simple. New adapter part without forming a new female thread part on the wall surface by simply adding a support member that can be screwed in space-saving It can be fixed to the old spacer member.

That is, in a state where the new adapter member is hooked on the old spacer member, the spacer side female thread portion formed on the spacer side fixing piece exposed below the lower end portion of the adapter side fixing piece is connected to the spacer side female screw portion. Adapter side screw formed on the adapter side fixing piece by fixing the supporting side screw insertion hole formed on the supporting side fixing piece and fixing the supporting side locking piece formed extending from the supporting side fixing piece in the same supporting member. The new adapter member can be fixed to the old spacer member in a state where the adapter side fixing piece is in close contact with the spacer side fixing piece by fixing the indicating member to the spacer member in a state of being locked in the insertion hole. . In addition, the support member has a configuration that can be manufactured in a small and inexpensive manner, including a support-side fixing piece and a support-side locking piece, and a support-side screw insertion hole is screwed to the spacer-side female thread portion. Therefore, the new adapter member can be fixed to the old spacer without damaging the low-cost and space-saving merit of the gas meter fixture.
Therefore, according to the present invention, it is possible to realize a gas meter fixing method and a gas meter fixing tool that do not impair the low-cost and space-saving merit of the gas meter fixing tool as much as possible and do not require complicated work.

  According to a second characteristic configuration of the gas meter fixing method according to the present invention, the support member is in a state where the support side screw insertion hole is screwed to the spacer side female screw portion, and the support member locking portion is the adapter side screw. The inner diameter surface of the insertion hole is elastically pressed and fixed toward the support side screw insertion hole side.

  According to the second characteristic configuration, the support member locking portion of the support member in which the support side screw insertion hole is fixed to the spacer side female screw portion has the inner diameter surface of the adapter side screw insertion hole on the support side screw insertion hole side. Since the new adapter member is favorably restrained from being displaced in the direction opposite to the pressing direction by being elastically pressed and fixed, the adapter side engagement hole of the new adapter member is It is possible to satisfactorily prevent the member from being detached from the spacer-side engagement hook. Further, the new adapter member rotates around the adapter side engagement hole engaged with the spacer side engagement hook by the pressing force against the inner surface of the adapter side screw insertion hole by the support member locking portion as described above. Since the displacement is also suppressed well, the rattling of the new adapter attached to the old spacer can be suppressed well, so that the new gas meter can be fixed to the wall surface in a good state.

  A third characteristic configuration of the gas meter fixing method according to the present invention is that the support member is formed of a single saddle for fixing a pipe material.

  According to the third characteristic configuration, the support member composed of the support-side fixing piece and the support-side locking piece as described above can be configured with a single piece saddle for fixing a pipe material that is commercially available and inexpensively available. it can. That is, the piece saddle for fixing the tube material is composed of a flat plate portion in which a screw insertion hole for screw fixation is formed, and a support portion extending in a semicircular shape in a form of gripping the outer periphery of the tube material from the flat plate portion, In the form in which the flat plate portion is the support side fixing piece and the support portion is the support side locking piece, the pipe material fixing piece saddle can be used as a support member used in the gas meter fixing method of the present invention. .

Embodiments of the present invention will be described with reference to the drawings.
A gas meter fixture 100c shown in FIGS. 1 and 2 (a) and 2 (b) includes a spacer fitting 20 (an example of a spacer member) fixed to a wall 1 such as a house, and a gas meter 10 while fixing the gas meter 10 to the spacer fitting 20. It consists of an adapter fitting 30 (an example of an adapter member) to be fixed.
The spacer metal fitting 20 is formed on the wall surface 1 and has a wall surface fixing piece 21 in which a screw insertion hole 22 is formed to be fixed to the screw portion with a screw S, and a spacer side fixing piece arranged at a predetermined interval from the wall surface 1. 25. On the other hand, the adapter fitting 30 has an adapter side fixing piece 35 fixed to the spacer side fixing piece 25 and a gas meter fixing piece 31 in which a support hole 32 for fixing the gas meter 10 is formed.
Further, the adapter side fixing piece 35 is formed with a pair of adapter side engagement holes 36 and adapter side screw insertion holes 37 symmetrically. On the other hand, a pair of spacer-side engagement hooks 26 and spacer-side female screw portions 27 are formed symmetrically on the spacer-side fixing piece 25 corresponding to the adapter-side engagement holes 36 and the adapter-side screw insertion holes 37. Yes.

The method for fixing the spacer metal fitting 20 to the wall surface 1 will be described. The screw insertion hole 22 formed in the wall surface fixing piece 21 of the spacer metal fitting 20 is formed in the wall surface 1 and is fixed to the screw portion with the screw S. Thus, the spacer fitting 20 can be fixed to the wall surface 1.
On the other hand, when a method for fixing the gas meter 10 to the adapter fitting 30 is described, the pair of pipe joints 12i and 12o formed as pipe screws protruding upward from the inlet side and the outlet side of the gas meter 10 are described above. It inserts into a pair of support hole 32 formed in the gas meter fixed piece 31 which the adapter metal fitting 30 has, and connects to a pair of U vent pipe 4i, 4o arrange | positioned above it. And the edge part of the support hole 3 of the said adapter metal fitting 30 is pinched | interposed by a pair of fixing nut 5i, 5o and the said U vent pipe 4i, 4o which were previously attached to each of a pair of pipe joints 12i, 12o. Thus, the gas meter 10 can be fixed to the adapter fitting 30 by tightening the fixing nuts 5i, 5o upward.

  Furthermore, in the gas meter fixture 100c of this embodiment, as shown in FIG. 2 (a), the adapter side fixing interval Ha, which is the interval of the adapter side screw insertion hole 37 with respect to the adapter side engagement hole 36 in the adapter fitting 30, is It is smaller than the spacer-side fixing interval Hb, which is the interval of the spacer-side female thread portion 27 with respect to the spacer-side engagement hook 26 in the spacer metal fitting 20.

As described in the background art section, this is the new adapter metal fitting 30a that constitutes the new gas meter fixture 100a (see FIG. 6) for fixing the new gas meter. The spacer bracket 20 is an old spacer bracket 20b constituting a new gas meter fixture 100b (see FIG. 7) for fixing the old gas meter. The new gas meter fixture 100a is lower in cost than the old gas meter fixture 100b. Moreover, in order to save space, the size is particularly small with a reduced size in the height direction.
In the drawings, in order to distinguish between various main parts of the new adapter bracket 30a and various main parts of the old spacer 20b, the number corresponding to the corresponding part is suffixed with “a” in the case of the new model. In some cases, an old model is indicated with “b”.

Therefore, normally (that is, the new gas meter fixture 100a or the old gas meter fixture 100b in which the adapter side fixing interval Ha of the adapter fitting 30 and the spacer side fixing interval Hb of the spacer fitting 20 have the same dimensions) are shown in FIGS. As shown, the adapter side screw insertion hole 37 is inserted into the spacer side female thread portion 27 in a state where the adapter side engagement hole 36 is engaged with the spacer side engagement hook 26 and the adapter metal fitting 30 is hooked on the spacer metal fitting 20. The adapter fitting 30 can be fixed to the spacer fitting 20 by being fixed with the screw S.
However, in the gas meter fixture 100c of the present embodiment, as shown in FIG. 2B, in the state where the new adapter fitting 30a is hooked on the old spacer fitting 20b, the position of the spacer-side female thread portion 27b is Without being aligned with the position of the screw insertion hole 37a, the adapter side fixing piece 35a is exposed below the lower end portion of the adapter side fixing piece 35a, and the adapter side screw insertion hole 37a is directly screwed to the spacer side female screw portion 27b. Is no longer possible.

  As described above, in the gas meter fixture 100c including the old spacer fitting 20b and the new adapter fitting 30a, the new adapter fitting 30a can be replaced with the old spacer fitting without directly fixing the adapter side screw insertion hole 37a to the spacer side female thread portion 27b. If the old gas meter can be fixed to the wall surface 1, for example, when the old gas meter is replaced with the new gas meter, the old spacer metal fitting 20b already fixed to the wall surface can be used as it is. It is not necessary to form a new female screw portion for fixing the new spacer fitting 20a (see FIG. 6).

  And about the gas meter fixing tool 100c which concerns on a present Example, as shown in FIG.3, FIG.4 and FIG.5, the low cost and space-saving merit in the gas meter fixing tool 100c is not impaired as much as possible, and complicated work is required. However, it is possible to realize the fixing of the new adapter metal fitting 30a to the old spacer metal fitting 20b only by adding a support metal fitting 40 (an example of a support member) to be described later. The support metal fitting 40 will be described in detail below. To do.

  As shown in FIGS. 3 and 4, the support fitting 40 includes a support-side fixing piece 41 in which a support-side screw insertion hole 42 that is fixed to the spacer-side female thread portion 27b by a screw S is formed, and a support-side screw insertion.

Become.

  Further, as shown in FIG. 5, this type of support fitting 40 can be configured by a commercially available piece saddle for fixing a pipe material, and this piece saddle is used as a support side screw insertion hole 42. A flat plate portion in which a screw insertion hole for functioning screw fixing is formed functions as the support-side fixing piece 41, and a support portion extending in a semicircular shape so as to grip the outer periphery of the tube material from the flat plate portion is the support member. It functions as the side locking piece 43.

  Therefore, in a state where the new adapter member 30a is hooked on the spacer member 20b, the support side screw insertion hole 42 of the support fitting 40 is fixed to the spacer side female thread portion 27b with the screw S, and the support side engagement of the support fitting 40 is also performed. The new adapter member 30a is fixed to the old spacer member 20b by attaching the support fitting 40 in such a manner that the distal end portion 44 of the stopper piece 43 is locked to the adapter side screw insertion hole 37a.

  Further, while the tip end portion 44 of the support side locking piece 43 is locked to the adapter side screw insertion hole 37a, the support side screw insertion hole 42 is moved to the spacer side female screw portion 27b while pulling the support fitting 40 downward. The support fitting 40 is attached so that it is fixed to the screw S. The support fitting 40 attached in this way has the support side screw insertion hole 42 fixed to the spacer side female thread portion 27b with the screw S, and the support side locking portion 43 has the inner diameter surface of the adapter side screw insertion hole 37a. It is elastically pressed and fixed toward the support side screw insertion hole 42 side. That is, the distal end portion of the support side locking portion 43 of the support fitting 40 attached to the old spacer 20b is positioned below the adapter side screw insertion hole 37a of the new adapter member 30a in the natural state, and the distal end portion thereof. Is displaced upward with elastic deformation and locked in the adapter side screw insertion hole 37a, so that the inner diameter surface of the adapter side screw insertion hole 37a is moved to the support side screw insertion hole 42 side by the support side locking portion 43. It will be elastically pressed toward. Therefore, the adapter-side engagement hole 36a of the new-type adapter member 30a is satisfactorily prevented from coming off from the spacer-side engagement hook 26b of the old-type spacer member 20b, and the rattling of the new-type adapter 30a attached to the old-type spacer 20b is further prevented. Suppression is also well controlled.
