(57) [Summary] [Purpose] I would like to avoid installing the T-NCU on the outer wall of a building or the wall of a pipe shaft. [Constitution] L-type mounting bracket body 24, metal fixing band 2
6. The T-NCU 22 is directly attached to the rising pipe 21 of the gas meter 20 using the T-NCU attachment 31.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting bracket for mounting a terminal network control device.

[0002]

[Prior art]

 When communication other than telephone is performed using the telephone line, a terminal network control device (hereinafter referred to as "T-NCU") is attached to the telephone line. Fig. 4 shows this example, 1 is a telephone line, 2 is a telephone, 3 is a protector, 4 is a T-NCU, 5 is a gas meter with an alarm circuit 6, and 7 is a riser tube with a gas meter 5 attached. Then, the protector 3 and the T-NC U4 are usually mounted side by side on the outer wall 9 using the wooden plate 8. In the case of collective housing, it is usually attached to the concrete wall inside the pipe shaft.

[0003]

[Problems to be solved by the device]

 As described above, in the conventional example, the protector 3 and the T-NCU 4 are mounted side by side on the outer wall 9 of the building or the concrete wall inside the pipe shaft, and therefore have the following drawbacks.

A. Spoil the aesthetics of the building.

B. Installation work becomes difficult in a narrow pipe shaft.

C. Since the signal line 10 connecting the T-NCU 4 and the alarm circuit 6 of the gas meter 5 becomes long, troubles are likely to occur during this period.

D. If the mounting positions of the T-NCU 4 are far apart, the wiring component 11 must be used between the lead wire on the gas meter 5 side.

An object of the present invention is to attach a T-NCU to the outer wall of a building or the inner wall of a pipe shaft as in the conventional case when it becomes necessary to attach a T-NCU in connection with a gas meter. It is to propose a mounting bracket that can be completed.

[0009]

[Means for Solving the Problems]

 The structure of the fitting according to the present invention is as follows.

A flat L-shaped mounting metal fitting main body formed by forming a fixing means for horizontally fixing to a rising inlet pipe or an outlet pipe of a gas meter, and forming terminal network control device fixing means on the other side, A terminal network control device mounting bracket comprising a rear surface of the terminal network control device and a mounting bracket fixed to the terminal network control device fixing means.

[0011]

[Action]

 Attach the mounting bracket to the terminal network control device fixing means of the mounting bracket body using screws, etc., then attach the terminal network control device to this mounting bracket, and then horizontally mount the mounting bracket body to the rising pipe using the fixing means. Install.

【Example】

 FIG. 1 is a side view showing a state in which a T-NCU 22 is attached to a riser pipe 21 of a gas meter 20 with an alarm circuit 20 'by using an L-shaped mounting bracket 23 according to the present invention, and FIG. 2 is an L-shaped mounting bracket. FIG. 23 is an exploded perspective view showing the configuration of 23. In FIG. 2, reference numeral 24 is an L-type mounting metal fitting body, 25 is a fixing portion for the rising pipe 21 formed in the L-type mounting metal fitting body 24, and 26 is a metal band as a fixing means attached to the fixing portion 25. The L-shaped metal fitting body 24 is horizontally attached to the rising pipe 21 by utilizing the metal band 26.

Reference numeral 27 is a mounting screw for fixing the metal band 26 to the L-shaped metal fitting body 24, 27 ′ is a nut, and 28 is a mounting hole provided in the fixing portion 25. The L-type fitting main body 24 may be fixed to the rising pipe 21 by another method.

Reference numeral 29 denotes a T-NCU mounting portion of the L-shaped mounting bracket body 24, and the T-NCU mounting portion 29 is provided with a screw hole 30. 31 is a T-NCU mounting bracket fixed to the back surface of the T-NCU 22, and the T-NCU mounting bracket 31 has an insertion part 32 into which the T-NCU fixing part 29 of the L-shaped mounting bracket body 24 is inserted. In addition to being formed, the insertion portion 32 has a vertical elongated hole 33 and a horizontal elongated hole 34 formed in the upper and lower sides. Reference numeral 35 is a screw hole, and 36 is an engaging portion. Reference numeral 37 is a screw hole on the T-NCU 22 side, and 38 is an engaging piece with which the engaging portion 36 provided on the back surface of the T-NCU 22 engages. Reference numeral 39 is a bus, and 40 in FIG. 1 is a signal line.

A procedure for attaching the T-NCU 22 using the attachment fitting 23 will be described below. First, the T-NCU mounting bracket 31 is attached to the T-NCU mounting portion 29 of the L-shaped mounting bracket body 24, and the screw 39 is used to pass the screw 39 through the vertical elongated hole 33 and the horizontal elongated hole 34 into the screw hole 30. Screw in here and fix the T-NCU mounting bracket 31. Next, in this state, the engaging portion 36 of the T-NCU mounting bracket 31 is inserted into the engaging piece 38 on the rear surface of the T-NCU 22 from below, and the screw 39 is screwed into the screw hole 37 from the screw hole 35. The T-NCU mounting bracket 31 is fixed to the rear surface of the T-NCU 22 with. Next, the fixing portion 25 of the L-shaped fitting main body 24 is horizontally fixed to a predetermined position of the rising pipe 21 by using the metal band 26 of the L-shaped fitting main body 24, the mounting screw 27, and the nut 27 '. As a result, the T-NCU 22 is horizontally mounted immediately beside the gas meter 20 toward the front side.

[0016]

[Effect of device]

 As described above, according to the present invention, since the T-NCU is directly attached to the rising pipe in the vicinity of the gas meter, it is not necessary to attach the T-NCU to the outer wall of the building as in the conventional case. As a result, there is no fear of spoiling the appearance of the outer wall, and the signal line connecting the alarm circuit or automatic meter reading circuit in the gas meter may be short, thus eliminating line trouble. Also, inside the pipe shaft, installation work can be easily performed even in a narrow space.
