[0004]

[Problems to be solved by the device]

 It is desirable that the insertion hole 4a be as small as possible for reasons such as downsizing of the mounting plate 3. However, the mounting device has a problem that it is difficult to make the insertion hole 4a small.

That is, in order to press and fix the holder 2 to the mounting plate 3, the tip of the holder 2 is inserted into the insertion hole 4a. Therefore, in order to make the insertion hole 4a small, it is necessary to make the tip of the holder 2 small. However, a flange portion (projecting piece) 2c protruding outward is formed at the tip of the holder 2, and the screw hole 2a and the screw insertion hole 2b are formed in the flange portion 2c. In this way, if the flange portion 2c is formed so as to project outward, the tip portion of the holder 2 becomes larger by that amount. Therefore, the insertion hole 4a could not be made smaller.

[0006]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, and it is attached to the main body of the device fixed to the inside of the wall and the main body of the device with the tip part inserted into the insertion hole formed in the wall. A holder that is movably supported inward and outward of the wall and has a gas stopper attached inside, and a mounting plate that has a window hole facing the insertion hole and is pressed into contact with the wall surface on the indoor side of the wall. The mounting plate is press-fixed to the wall by a bolt that penetrates the mounting plate and is screwed into the screw hole of the apparatus body, and penetrates the mounting plate and is screwed into the screw hole of the holder. In the gas plug mounting device in which the holder is fixed to the mounting plate by the bolts, a protruding piece protruding inward in the radial direction of the insertion hole is formed in the holder, and the screw is attached to the protruding piece. It is characterized by forming holes.

[0007]

[Action]

 Since the protruding piece is formed so as to protrude inward in the radial direction of the insertion hole, it is not necessary to enlarge the insertion hole by the amount of the protruding piece. Therefore, the insertion hole can be made smaller.

Next, a description will be given of a case where the mounting apparatus 10 having the above-mentioned configuration is used to mount the gas plug G in a state of being built in the wall. At the time of mounting, as shown in FIG. 2, the insertion hole 12a is formed in the inner wall 12 on the indoor side in advance, and the gas plug G is mounted on the holder 30 in advance. In this case, the size of the insertion hole 12a is set to be substantially equal to or slightly larger than the size of the holder 30. In the attached state, the gas plug G has the connecting portion G ₁ facing the open side of the holder 30 and the plug portion G ₂ facing forward.

First, the device body 20 is fixed inside the wall. In this embodiment, the end plate 23 is butted against the crosspiece 13 arranged between the inner wall 12 and the outer wall (not shown) and fixed by the screw 14, but the bottom plate 21 is butted against the outer wall. It may be fixed. The fixing of the device body 20 is performed before the inner wall 12 is constructed.

Next, the side plate 32 A or 32 C of the holder 30 and the inner plate part 36 are inserted into the guide part 26 of the apparatus body 20. After insertion, the inner wall 12 is constructed. Next, with the mounting plate 40 pressed against the indoor side wall surface of the inner wall 12, the bolts 15 and 15 are respectively inserted into the two screw insertion holes 45 and 45 located on the diagonal line, and the screw insertion hole of the holder 30 is further inserted. 38, 38 are passed through and screwed into the screw holes 28, 28 of the apparatus main body 20, respectively. Then, by tightening the bolts 15 and 15, the mounting plate 40 is pressed against the inner wall 12 and fixed.

Next, the bolts 16 and 16 are inserted into the two screw insertion holes 45 and 45 located on the other diagonal line of the mounting plate 40 and screwed into the screw holes 39 and 39 of the holder 30. Then, by tightening the bolts 16 and 16, the protruding pieces 37 and 37 of the holder 30 are pressed against the contact pieces 44 and 44 of the mounting plate 40, and the holder 30 is fixed to the mounting plate 40. Then, the decorative plate 50 is fixed to the mounting plate 40.

As described above, in a normal operation, the apparatus main body 20 is fixed, the gas plug G is fixed to the holder 30, and the inner wall 12 is constructed later. In such a case, it is convenient to use the position confirmation jig 60 shown in FIG. The jig 60 is formed by molding resin, and has a substantially square rectangular tube portion 61, a connecting plate portion 62 formed on the inner peripheral surface of the rectangular tube portion 61, and the connecting plate portion. And a cylindrical portion 63 formed in 62. A projecting piece 64 projecting downward is formed at a lower end portion of one side of the rectangular tubular portion 61, and a notch portion 65 through which the connecting portion G ₁ of the gas stopper G is inserted is formed in the cylindrical portion 63. ing.

When the jig 60 having the above-described configuration is attached to the attachment device 10, the cylindrical portion 63 is inserted until the lower end of the rectangular tubular portion 61 abuts the protruding piece 37 of the holder 30.

Therefore, when the inner wall 12 is constructed, it is attached to the inner wall 12. It is possible to reliably prevent the construction of the hole for the attachment device 10 without making a hole. Moreover, the holes can be accurately formed by using the rectangular tube portion 61 as a kind of template. Of course, when the inner wall 12 is constructed, the jig 60 is removed. Further, the rectangular tube portion 61 of the jig 60 can also be used as a template when a paper sheet or the like is attached to the inner surface of the inner wall 12 after the inner wall 12 is constructed.

In the mounting device 10 having the above-described configuration, since the projecting piece 37 of the holder 30 projects toward the inside of the holder 30, it is necessary to increase the size of the insertion hole 12 a by the size of the projecting piece 37. Absent. Therefore, the size of the insertion hole 12a can be made as small as possible.

It should be noted that the present invention is not limited to the above-described embodiment, and can be modified as appropriate without departing from the spirit of the invention. For example, in the above embodiment, the holder 30 is provided with four projecting pieces 37, but only the two projecting pieces 37 having the screw holes 39 are formed to form the screw insertion holes 38. The protruding piece 37 need not be formed. Further, the protruding pieces 37 may be connected to each other to form a so-called flange shape.

Further, as shown in FIG. 3, when the inner wall 12 is thick, a cylinder is provided between the protruding piece 37 of the holder 30 in which the screw hole 39 is formed and the abutting piece 44 of the mounting plate 40. A color-shaped color 70 may be arranged and the holder 30 may be fixed to the mounting plate 40 via the collar 70.
