Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a gas meter fixing fitting for fixing a gas meter to, for example, a wall surface of a building.

[0002]

[Prior art]

 From the perspective of disaster prevention, some gas meters installed in ordinary households are equipped with a seismic sensing device that detects an earthquake that exceeds the specified seismic intensity.

Such a seismic sensor basically senses an earthquake based on the rocking state of the gas meter. In other words, when the gas meter oscillates, if the oscillating characteristics such as the amplitude and period of the oscillating coincide with the oscillating characteristics of the quake caused by the earthquake, the seismic sensing device should detect the occurrence of the earthquake. Becomes When an earthquake is detected, the seismic sensor outputs a signal to that effect, and the emergency operation instruments operate based on the output signal, for example shutting off the gas supply.

[0004]

[Problems to be solved by the device]

 By the way, as shown in Fig. 6, in the case of a detached house, install the gas meter (3) so that it is suspended at the folded end of the gas pipe (2) (2) that is pulled out from the ground to the ground. May be The height position of such a gas meter (3) is normally set to 1200 mm or more from the ground (1) so that the meter display can be visually observed in a comfortable posture. The gas pipe length up to 3) is about 1700 mm.

In this installed state, when a large truck runs near the gas meter (3) or when an article is inadvertently collided with the gas meter (3), the gas meter (3) swings with a span of 1700 mm. Move. The rocking characteristics at this time are similar to the rocking characteristics due to the earthquake, while they rock for a long time due to rocking back. For this reason, the seismic shock absorber may operate in the same way as when an earthquake occurs due to this oscillation.Even if no earthquake occurs, the emergency operation instruments will operate and the gas supply There was a risk that it would be cut off. In this way, when the gas supply is interrupted only by running the vehicle or collision of the articles, it is necessary to perform the recovery work such as releasing the interrupt of the gas each time.

This invention solves the above-mentioned problems of the prior art, and can prevent the operation of the emergency operation instruments of the gas meter except when an earthquake occurs, for example, when the vehicle is simply running or when an article collides, while an earthquake actually occurs. In this case, it is an object of the present invention to provide a gas meter fixing bracket that can operate emergency operation instruments without any trouble.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the gas meter fixing metal fitting according to claim 1 comprises a metal fitting main body having a pair of clamp claws facing each other and capable of sandwiching an outer peripheral edge portion of the gas meter. The mounting stay is slidable along its longitudinal direction and fixedly mounted at any sliding position, so that one end of the mounting stay can be advanced from the metal fitting body and fixed at any advanced position. In addition, a mounting piece is provided at one end of the mounting stay, which can be fixed around the gas meter via a fastener.

Further, the invention according to claim 2 is the fixing metal fitting according to claim 1, wherein the metal fitting body is mounted on the base plate and slidably on the base plate so as to be fixed at an arbitrary slide position. The clamp claw on one side of the pair of clamp claws is formed by bending a part of the substrate, while the clamp claw on the other side includes a movable plate. It is formed by bending in the same direction as the bending direction of the clamp claw on the one side, and at least one of the clamp claws on the one side and the other side is inclined in opposite directions.

[0009]

[Action]

 In the gas meter fixing fitting according to claim 1, since the mounting stay is slidably attached to the fitting main body having a pair of clamp claws capable of sandwiching the outer peripheral edge portion of the gas meter, the pair of clamp claws are used. If the mounting station is fixed to a part such as a building wall surface while the gas meter is sandwiched, the gas meter will be fixed to that part. Therefore, even if a vehicle travels or an article collision occurs, the swing of the gas meter is suppressed, and the swing of the gas meter that is confusing with the swing during an earthquake does not occur. In addition, when an earthquake actually occurs, the entire surface of the ground, including parts such as the building wall surface, sways, so the gas meter also oscillates with these, and the seismic sensor of the gas meter accurately detects the occurrence of the earthquake. .

In this gas meter fixing bracket, the outer peripheral edge of the gas meter is clamped by the clamp claws, the mounting stay is slid, and the mounting piece of the stay is attached to a site such as a building wall surface and fixed by a fixing tool. The installation work is completed just by doing.

In the metal fitting for gas meter fixing according to claim 2, since at least one of the pair of clamp claws is inclined in the opposite direction, the outer peripheral edge of the gas meter is clamped by the clamp claws. At that time, even if the clamping force on the tip side of the clamp claw becomes strong and a force that causes the clamp claw to come off the gas meter acts, a strong drag force is generated in the direction opposite to the direction of the removal.

【Example】

 As shown in FIG. 1, in the case of a detached house, the gas pipes (12) (13) buried in the ground are pulled out to the ground side in parallel with each other, and each gas pipe (12) The upper ends of (13) are folded back, and the upper ends of the gas meters (20) are connected to these folded back ends.

The gas meter (20) has an upper case (21) and a lower case (22). The lower case (22) is formed with a recess (23) continuously from one side surface to the other side surface through the lower surface, and the recess (23) allows the lower case (22) to move to the front region (22a). Is separated into a rear region (22b). Further, on the lower end surface of the lower case (22), a rib (24) is formed between the front region (22a) and the rear region (22b) so as to be bridged therebetween.

As shown in FIGS. 1 and 2, between the gas meter (20) and the building wall surface (15), a gas meter fixing metal fitting (30), which is a feature of this embodiment, is provided. In the following description of the gas meter fixing bracket (30), for the purpose of facilitating the understanding of the invention, the direction corresponding to the left direction toward the paper of FIG. 2 is the forward direction, and the direction corresponding to the right direction. Will be described as a backward direction.

As shown in FIGS. 1 to 4, the gas meter fixing fitting (30) includes a fitting body (40) and a mounting stay (50), and the fitting body (40) is a base plate. (31) and a movable plate (41) arranged on the substrate (31). The board (31) is formed by cutting and raising a front center region to form a clamp claw (32) on one side, and a notch (32a) is formed at the center of the upper end of the clamp claw (32). To be done. The cut-and-raised angle (θ 1) of the clamp claw (32) on the one side is set in the range of 95 degrees to 100 degrees, and the clamp claw (32) is set in a posture inclining rearward. .

Further, the front side regions of the substrate (31) are respectively bent downward to form screw insertion pieces (33) (33). The substrate (30) is provided with a support piece (35) extending rearward in a strip shape, and the support piece (35) is provided with an elongated hole (34) extending in the longitudinal direction thereof.

The front part of the movable plate (41) is cut and raised upward to form the clamp claw (42) on the other side. The cut-and-raised angle (θ 2) of the clamp claw (42) on the other side is set in the range of 80 degrees to 85 degrees, and the clamp claw (42) is set in a posture inclining forward. .

Further, the front both side regions of the movable plate (41) are respectively bent downward to form screw fastening pieces (43) (43), and each of the screw fastening pieces (43) (43) is A threaded hole (43a) (43a) is formed in each. Further, in the central portion of the movable plate (41), two screw cutting holes (44) (44) are formed corresponding to the elongated holes (34) of the substrate (31).

The L-shaped mounting stay (50) is connected to the support piece (51) extending in the front-rear direction and the rear end of the supporting piece (51), and is attached downwardly to the mounting piece (52). And have. A long hole (54) extending in the longitudinal direction is formed in the support piece (51), and two screw insertion holes (52a) (52a) are formed in the mounting piece (52) at upper and lower positions. .

Then, the supporting piece (35) of the substrate (31) is superposed on the supporting piece (51) of the mounting stay (50) so that these long holes (34) (54) fit each other. At the same time, the movable plate (41) is superposed on the supporting piece (35) of the substrate (31) so that the threaded holes (44) thereof match the long holes (34) and (54), respectively. In that state, the two screws (60) (60) are inserted into the elongated holes (54) (34) from below the mounting stay (50) respectively, and the threaded holes (44) ( 44). Further, from the front of the board (31), long screws (61) (61) are inserted into the through holes of the screw insertion pieces (33) (33) respectively, and the screw holes (43a) of the movable plate (41) are inserted. Fasten each to (43a). As a result, the metal fitting (30) for fixing the gas meter is formed.

In the metal fitting (30), when the screws (60) (60) are loosely fastened, the pressing force of the mounting stay (50) toward the substrate (31) side becomes small, and the mounting stay (50) is The base plate (31) can be slid along the direction in which the elongated hole (54) extends, and the mounting piece (52) of the mounting stay (50) can be moved back and forth with respect to the base plate (31). Further, in this state, the pressing force of the substrate (31) to the movable plate (41) side is also reduced, and the movable plate (41) can slide along the direction in which the elongated hole (34) extends with respect to the substrate (31). By rotating the long screws (61) and (61) respectively, the movable plate (41) slides on the substrate (31) by an amount corresponding to the amount of rotation. As a result, the clamp claw (42) on the other side of the movable plate (41) moves toward and away from the clamp claw (32) on the one side of the substrate (31).

Further, when the screws (60) (60) are firmly fastened, the pressing force of the mounting stay (50) to the board (31) side becomes large, and the sliding movement of the mounting stay (50) is restricted. At the same time, the pressing force of the substrate (31) toward the movable plate (41) also increases, and the sliding movement of the movable plate (41) is restricted.

In order to fix the gas meter (20) with the gas meter fixing bracket (30) configured as described above, first, the fastening state of the screws (60) (60) of the fixing bracket (30) is loosened. Meanwhile, the long screws (61) (61) are rotated to keep a relatively large distance between the clamp claws (32) (42), that is, the opening amount.

As shown in FIGS. 1 and 2, the center of the lower edge of the lower case rear region (22b) of the gas meter (20) is provided with both clamp claws (32) (42) of the gas meter fixing bracket (30). Fit in between. At this time, the ribs (23) are positioned in the notches (32a) of the clamp claws (32) on one side so as to reach the deep positions of the clamp claws (32) (42) under the lower case rear region (22b). Fit the edges.

Subsequently, the long screws (61) (61) are respectively rotated in the fastening direction to move the clamps (42) on the other side to the clamps (32) on the one side, and the clamps (32) on both sides are moved. ) (42) holds the lower edge of the lower case rear region (22b).

Next, the mounting stay (50) is appropriately slid so that the mounting piece (52) of the stay (50) is placed along the building wall surface (15). Then, the screws (60) (60) are firmly fastened to restrict the sliding movement of the stay (50), and the screws (62) (62) are fitted into the screw insertion holes (52a) (52a) of the mounting piece (52). And fasten it to the building wall (15). This completes the work of fixing the gas meter (20) by the gas meter fixing fitting (30).

Either the clamping work of the gas meter (20) by the clamps (32) (42) or the screwing work of the station (50) to the building wall surface (15) may be performed first.

Even when a large truck runs near the gas meter (20) or an article is inadvertently collided with the gas meter (20) with the gas meter fixing bracket (30) attached, Since the gas meter (20) is fixed to the building wall surface (15) via the fixing metal fittings (30), the swing of the gas meter (20) is suppressed, and the seismic shock absorber installed in the gas meter (20) causes an earthquake. It doesn't work the same way as it does. For this reason, the gas supply is not interrupted only by simple vehicle travel, article collision, etc., and complicated recovery work at that time is also unnecessary.

On the other hand, when an earthquake actually occurs, the entire surface of the ground including the building sways, so that the gas meter (20) also sways with them. Needless to say, the shaking at this time has the shaking characteristics itself due to the earthquake, so the seismic sensing device of the gas meter (20) accurately senses the occurrence of the earthquake and shuts off the gas supply, etc. , Emergency operation instruments are activated.

Further, in this embodiment, the gas meter fixing metal fitting (30) is mounted by adjusting the long screws (61) (61) and using the clamp claws (32) (42) to attach the lower edge of the gas meter (20). This is completed simply by sandwiching the parts, sliding the mounting stay (50), and screwing the mounting piece (52) along the building wall surface (15).

Further, in the above-described embodiment, since the pair of clamp claws (32) (42) are inclined in the direction in which they face each other, the gas meter ( 20) When the lower edge part of the clamp claw is clamped, the clamping force on the tip side of the clamp claw becomes strong, and even if a force is applied to the pair of clamp claws (32) (42) to disengage from the gas meter (20), A strong reaction force is generated in a direction opposite to the direction in which the force acts, and the clamp claws (32) (42) can be efficiently prevented from being detached from the gas meter (20).

Furthermore, in the above-described embodiment, the load on the connecting portion such as the base provided in the connecting portion between the gas pipes (12) and (13) and the gas meter (20) can be reduced. That is, in the conventional structure shown in FIG. 6, since the gas meter is suspended in the gas pipe via the connecting portion, the load is concentrated on the connecting portion. On the other hand, in the structure of this embodiment, since the lower edge of the gas meter (20) is supported by the building wall surface (15) via the fixing metal fitting (30), the load is fixed by the fixing metal fitting (30). ) And the connection part, local concentration of load is avoided, and damage to parts can be effectively prevented.

FIG. 5 is a perspective view showing a modification of the usage state of the metal fitting (30) for fixing the gas meter according to the present invention. As shown in the figure, in this modified example, the mounting stay (50) of the metal fitting for gas meter (30) is fixed to the connecting band (14) for connecting the gas pipes (12) and (13). .

Since other configurations are the same as those of the above-described embodiment, the same reference numerals are given to the same portions and the description thereof will be omitted.

In this modification, since the lower edge of the gas meter (20) is fixed to the connecting band (14) of the gas pipes (12) and (13), the supporting path of the gas meter (20) from the ground is , The lower portion of the gas pipes (12), (13), the connecting band (14), and the gas meter fixing fitting (30). For this reason, the span of the installed gas meter is substantially shorter than that of the conventional example shown in FIG. 6, for example, and even if a vehicle travels or an article collision occurs, the gas meter (20) will not be shaken during an earthquake. It swings with a swing characteristic different from the dynamic characteristic, and the swing also stops in a short time. For this reason, the seismic sensing device of the gas meter (20) does not operate as if an earthquake had occurred due to mere vehicle traveling or collision of articles, and at that time, the emergency operation instruments operate to supply gas. Is never blocked.

Although the lower edge of the gas meter (20) is clamped by the clamp claws (32) (42) of the gas meter fixing bracket (30) in the above-mentioned embodiments and modifications, The sandwiching position by (32) and (42) may be a side edge portion of the gas meter (20) or any position as long as it is an outer peripheral edge portion of the gas meter (20).

Further, the portion for fixing the mounting stay (50) of the gas meter fixing metal fitting (30) is not limited to the building wall surface (15) and the connecting band (14), but the gas meter (20). Any part may be used as long as it is located in the vicinity of, and does not easily swing.

[Effect of device]

 As described above, according to the metal fitting for fixing a gas meter according to claim 1, since the mounting stay is slidably mounted on the metal fitting body having the pair of clamp claws that can sandwich the outer peripheral edge portion of the gas meter, If the mounting stay is fixed to a portion such as a building wall surface while the outer peripheral edge portion of the gas meter is sandwiched by the pair of clamp claws, the gas meter is fixed to that portion. Therefore, even if a vehicle travels or an article collision occurs, the rocking of the gas meter is suppressed, and the rocking of the gas meter is not confused with the rocking due to an earthquake. Therefore, the seismic sensing device of the gas meter does not operate like when an earthquake occurs due to mere vehicle travel or article collisions, and it is possible to prevent accidental operation of emergency operation instruments, for example, shutting off the gas supply. Can be stopped. In addition, when an earthquake actually occurs, the entire surface of the ground, including parts such as the walls of the building, shakes, so the gas meter also shakes, and the seismic sensing device accurately senses the occurrence of the earthquake and supplies the gas. The emergency operation instruments can operate without any trouble such as shutting off the power. Moreover, with this gas meter fixing bracket, you can easily clamp the outer peripheral edge of the gas meter with the clamp claws, slide the mounting stay, and fix the mounting piece with the fastener along the position of the building wall surface, etc. Can be installed.

Further, in the gas meter fixing fitting according to the second aspect, at least one of the pair of clamp claws is inclined in the opposite direction, so that the clamp claw clamps the outer peripheral edge portion of the gas meter. Even if the clamping claw on the tip side of the clamp claws becomes strong and the clamp claw is disengaged from the gas meter, a strong reaction force is generated in the direction opposite to the disengagement direction and the clamp claw is removed from the gas meter. The outside can be efficiently prevented.
