Description

  The present invention relates to a wiring fixture mounting body disposed on the back side of a wall material through a wall hole formed in the wall material, and a method for installing the wiring fixture mounting body.

  In order to install the wiring device on the wall of the building, a wiring device mounting body is disposed on the back of the wall. As this type of wiring fixture mounting body, for example, a wiring box disclosed in Patent Document 1 can be cited. In patent document 1, the bottomed square box-like wiring box which has an opening in the front surface is installed in the back side of the wall material. The wiring box has an opening that faces the wall front side through a wall hole, and a wiring device is accommodated in the wiring box through the wall hole. An abutting portion that abuts against the back of the wall is extended so as to be located on the same plane as the opening on the front edge of the wiring box and on the side edges of the upper and lower sidewalls. In Patent Document 1, since the distance between the contact portions is longer than the opening width in the vertical direction of the wall hole, if the wiring box is not inserted into the wall hole in a tilted state, Cannot install a wiring box in For this reason, there is a problem that it takes time to install the wiring box on the back of the wall, and it is necessary to provide a space on the back of the wall in which the inclined wiring box can be inserted.

  Then, in order to wipe off the troublesomeness of the insertion work from the wall surface of a wiring box, it is possible to use a wiring fixture attachment body like patent document 2. FIG. As shown in FIG. 10, the wiring fixture mounting body of Patent Literature 2 is a bottomed square box-like wiring box B having an opening K on the front surface, and a flange portion F is provided on the opening K side of the pair of side walls B1. And the rear surface of each flange portion F abuts against the wall surface. Further, the side wall B1 of the wiring box B is formed with an inner side of the wiring box B so as to be elastically deformable, and with a contact portion 1 that contacts the back of the wall. Specifically, the distance from the rear surface of the flange portion F to the contact surface 1a of the contact portion 1 is made different so that wall materials of various thicknesses can be sandwiched between the contact portion 1 and the flange portion F. A plurality of contact portions 1 are formed. And in patent document 2, even if it does not incline the wiring box B, it only contacts the wall surface because the flange part F remains on the wall surface by inserting it into the wall hole from the rear surface of the wiring box B, and the contact portion. When the elastic member 1 is elastically restored, it comes into contact with the back of the wall, and the wall material is sandwiched between the contact part 1 and the flange part F. As a result, the wiring box B is installed behind the wall.

Further, locking projections 17 as projections having a thin plate shape are respectively provided toward the front of the instrument mounting body 11 at the center in the short side direction of the instrument mounting body 11 on the front surfaces of the upper side wall 14a and the lower side wall 14b. Projected. As shown in FIGS. 1 and 2, the protruding length T1 of the locking protrusion 17 is the same as the thickness N3 of the wall W.

  And the boss | hub part 18 is provided in the inner surface of the upper side wall 14a and the lower side wall 14b, Comprising: The front side of the upper side wall 14a and the lower side wall 14b. That is, the locking protrusion 17 is formed in the vicinity of the boss 18 along the direction in which the boss 18 is opposed. A nut (not shown) is fitted into the boss 18 so as not to move in the thickness direction of the attachment body 12, and a female screw is formed on the inner peripheral surface of the boss 18 by the nut. Therefore, in this embodiment, the attachment part is formed of the boss part 18 and the nut. Each boss portion 18 is used to attach the wiring device H to the device mounting body 11 using a screw 43 as an attachment member.

  Further, the right side wall 14c and the left side wall 14d facing each other in a direction orthogonal to the facing direction of the boss portion 18 are respectively formed with flange portions 21 as contact portions that contact the back of the wall W (the back surface of the wall W). Yes.

And the contact surface 21a, the front surface of the boss | hub part 18, and the opening edge part of the opening K of the attachment body main body 12 are located on the same plane. Therefore, the locking protrusion 17 protrudes from the front surface (contact surface 21a) of the flange portion 21.

  As shown in FIG. 3, the length L3 between the outer end portions of the flange portion 21 along the short side direction of the instrument mounting body 11 is longer than the length N2 along the short side direction of the wall hole Wa. Yes. Here, the right side wall 14c and the left side wall 14d can be elastically deformed around their base ends. Since the flange portion 21 is formed integrally with the right side wall 14c and the left side wall 14d, the flange portion 21 can also be displaced toward the outside and inside of the attachment body 12. Therefore, it is impossible to insert the flange portion 21 into the wall hole Wa before the flange portion 21 is displaced to the inside of the attachment body 12. Further, the length L4 of the flange portion 21 along the long side direction of the instrument mounting body 11 is the same as the length L5 between both ends of the boss portion 18 along the long side direction of the instrument mounting body 11. . Therefore, the flange portion 21 is extended to the vicinity of the boss portion 18 along the facing direction of the boss portion 18.

  As shown in FIG. 4, a plurality (two in this example) of guide portions 22 are formed on the outer surfaces of the right side wall 14c and the left side wall 14d. The guide portion 22 forms a ridge and is inclined so as to protrude from the rear surface side of the attachment body 12 toward the front surface side. More specifically, as shown in FIG. 1, the guide portion 22 has one end positioned at the front end of the hole Q in the right side wall 14 c and the left side wall 14 d and the other end connected to the rear surface of the flange portion 21. Furthermore, the guide part 22 is extended so that it may protrude outward from the outer side edge part of the flange part 21, and may be located to the same plane as the contact surface 21a.

  Reinforcing ribs 23 are formed on the outer surfaces of the right side wall 14c and the left side wall 14d and at both ends in the length direction of the right side wall 14c and the left side wall 14d. The reinforcing ribs 23 are formed so as to be inclined while projecting from the rear surface side to the front surface side of the attachment body main body 12. More specifically, as shown in FIG. 1, one end of the reinforcing rib 23 is located at the rear ends of the right side wall 14 c and the left side wall 14 d, and the other end is connected to the rear surface of the flange portion 21.

  As shown in FIG. 2, in the guide portion 22 before being displaced to the inside of the attachment body 12, one point on the outer surface is set as a point X. If the length of the straight line connecting the points X in the short side direction of the attachment body 12 is L6, the length L6 is the same as the length N2 along the short side direction of the wall hole Wa. Yes. On the other hand, in the guide part 22 after being displaced to the inside of the attachment body 12, the length L7 of the straight line connecting the points X is shorter than the length N2 along the short side direction of the wall hole Wa. Yes.

Next, the instrument holding frame 40 that holds the wiring instrument H will be described.
As shown in FIG. 1, the instrument holding frame 40 is formed in a vertically long rectangular frame shape, and the instrument holding frame 40 is formed with a vertically long rectangular instrument holding hole 41. The length M1 along the long side direction of the instrument holding frame 40 is longer than the length N1 along the long side direction of the wall hole Wa. On the other hand, the length M2 along the short side direction of the instrument holding frame 40 is shorter than the length N2 along the short side direction of the wall hole Wa. A pair of insertion holes 42 are formed at substantially the center along the short side direction of the instrument holding frame 40 so as to penetrate the instrument holding frame 40 in the thickness direction so as to sandwich the instrument holding hole 41 therebetween. Each insertion hole 42 is formed in a long hole shape that is elongated in the short side direction of the instrument holding frame 40.

  Next, the effect | action of the instrument attachment body 11 is demonstrated according to FIGS. 5-8 with the method of installing the wiring instrument H in the wall W using the instrument holding frame 40. FIG. A cable C is wired behind the wall W.

  First, a wall hole Wa is drilled at a desired position of the wall W using an electric punch, and a cable C disposed on the back of the wall W is pulled out from the wall hole Wa to the wall W surface. Then, the operator P inserts the cable C drawn out on the surface of the wall W into the cable insertion hole 16 formed in the fixture attachment body 11 and then connects to the wiring fixture H.

  Next, the wiring device H is held in the device holding hole 41 of the device holding frame 40 and the screw 43 is inserted through the insertion hole 42 on the upper side of the device holding frame 40. And this screw | thread 43 is inserted in the boss | hub part 18 of the up-and-down both sides of the instrument attachment body 11, and is screwed in a nut, and the instrument attachment body 11 and the instrument holding frame 40 are temporarily fixed.

  Then, as shown in FIG. 5, the instrument mounting body 11 is inserted from the rear surface side of the mounting body main body 12 toward the wall hole Wa without being tilted while the instrument holding frame 40 is disposed on the front side of the wall W. Specifically, in the instrument mounting body 11, the instrument mounting body 11 is placed in the wall hole so that the standing direction of the side walls 14a to 14d from the bottom wall 13 is parallel to the direction in which the central axis of the wall hole Wa extends. Insert straight to Wa. At this time, the length L3 between the outer end portions of the flange portion 21 along the short side direction of the instrument mounting body 11 is longer than the length N2 along the short side direction of the wall hole Wa. Further, the length L6 between the guide portions 22 before being displaced to the inside of the attachment body 12 is the same as the length N2 along the short side direction of the wall hole Wa. Therefore, only by inserting the instrument mounting body 11 into the wall hole Wa, the substantially front half of the instrument mounting body 11 does not pass through the wall hole Wa, and the guide portion 22 is formed on the inner surface (inner wall Wb) of the wall hole Wa. It comes into contact. In addition, the instrument mounting body 11 is supported by the cable C by inserting the cable C through the cable insertion hole 16.

  Next, as shown in FIG. 6, the worker P presses the instrument mounting body 11 toward the back side of the wall hole Wa. Then, as the instrument mounting body 11 is pushed to the back side of the wall hole Wa, the guide portion 22 comes into sliding contact with the inner wall Wb of the wall hole Wa, so that the right side wall 14c and the left side wall 14d integral with the guide portion 22 are formed. It is elastically deformed toward the inside of the attachment body 12. With the elastic deformation of the right side wall 14c and the left side wall 14d, the flange portion 21 is also displaced to the inside of the mounting body main body 12.

  Thereafter, when the operator P further presses the instrument mounting body 11 toward the back side of the wall hole Wa, the entire instrument mounting body 11 including the flange portion 21 passes through the wall hole Wa. Then, the sliding contact of the inner wall Wb of the wall hole Wa with respect to the guide portion 22 is released, and the right side wall 14c and the left side wall 14d return to the original shape (original position). Then, the flange part 21 integrated with the right side wall 14c and the left side wall 14d returns to the shape before being displaced. That is, the flange portion 21 protrudes outward of the attachment body 12 at the back of the wall W. Moreover, the length M1 along the long side direction of the instrument holding frame 40 is longer than the length N1 along the long side direction of the wall hole Wa. Accordingly, as shown in FIG. 7, only the instrument mounting body 11 passes through the wall hole Wa and is disposed on the back side of the wall W, while only the instrument holding frame 40 is disposed on the front surface of the wall W.

  Moreover, the length L3 between the outer side edge parts of the flange part 21 along the short side direction of the instrument mounting body 11 is longer than the length N2 along the short side direction of the wall hole Wa. Therefore, even if the instrument holding frame 40 attached to the instrument mounting body 11 is pulled toward the front surface, the abutment surface 21a of the flange portion 21 abuts against the back of the wall W. It is not drawn out again to the surface of the wall W through the wall hole Wa.

  As shown in FIG. 8, the locking protrusion 17 is inserted into the wall hole Wa. Then, the locking protrusion 17 contacts the inner wall Wb of the wall hole Wa, and is positioned on the wall W so that the opening K of the instrument mounting body 11 faces the wall hole Wa. In this positioning state, the boss portion 18 also faces the front side of the wall W from the wall hole Wa.

  Subsequently, the screws 43 screwed into the nuts on both the upper and lower sides are further screwed into the instrument mounting body 11. When both the screws 43 are tightened, the instrument mounting body 11 is attracted to the wall W as the screws 43 are screwed into the nuts, and the wall between the contact surface 21a of the flange portion 21 and the instrument holding frame 40. W is pinched. Then, when the screw 43 is screwed into the nut, the wiring device H is installed on the front side of the wall W, so that the device mounting body 11 is installed on the back side of the wall W with the device holding frame 40 interposed therebetween. . At this time, since the flange portion 21 is extended to the vicinity of the boss portion 18 along the opposing direction of the boss portion 18, the flange portion 21 can easily come into contact with the wall W by screw tightening, as shown in FIG. The contact surface 21a of the flange portion 21 contacts the peripheral portion of the wall hole Wa on the rear surface of the wall W.

According to the above embodiment, the following effects can be obtained.
(1) A flange portion 21 that protrudes outward from the right side wall 14c and the left side wall 14d on the right side wall 14c and the left side wall 14d facing each other in the mounting body main body 12 and abuts against the back of the wall W is provided inside the mounting body main body 12. It was formed to be displaceable. Then, by inserting the attachment body main body 12 into the wall hole Wa from the rear side, the flange portion 21 is displaced inward so that the entire instrument attachment body 11 can be inserted into the wall hole Wa and the back of the wall W. For this reason, the whole instrument mounting body 11 can be easily inserted into the wall hole Wa and the back of the wall W without being inclined. Further, since it is not necessary to tilt the instrument mounting body 11, it is only necessary to form a space on the back of the wall W that can accommodate the instrument mounting body 11 that is not tilted. There is no need to provide it.

  (2) By making the right side wall 14c and the left side wall 14d of the instrument mounting body 11 elastically deformable toward the outer side and the inner side of the mounting body main body 12, the flange portion 21 integrated with the right side wall 14c and the left side wall 14d is also It is possible to displace the attachment body 12 outside and inside. And, by the displacement of the flange portion 21 to the inside of the attachment body 12, the entire instrument attachment body 11 can be disposed on the wall hole Wa and the back of the wall W. Therefore, unlike the wiring box B described in Patent Document 2, it is not necessary to provide a plurality of contact portions in order to cope with various wall thicknesses, so that the flange portion 21 can be formed large. Moreover, it becomes possible to raise the attachment strength to the wall hole Wa by forming the flange part 21 large.

  (3) The locking protrusions 17 that protrude from the contact surface 21a of the flange portion 21 are formed on the front surfaces of the upper side wall 14a and the lower side wall 14b. And when the flange part 21 contact | abutted the wall W back, the latching protrusion 17 was made to arrange | position inside the wall hole Wa. According to this, since the locking projection piece 17 comes into contact with the inner wall Wb of the wall hole Wa, the movement of the instrument mounting body 11 is limited, and the instrument mounting body 11 can be positioned behind the wall W. .

  (4) When the instrument mounting body 11 is pulled toward the wall W by tightening the screw 43, the locking projection 17 contacts the rear surface of the instrument holding frame 40, and the locking projection 17 functions as a stopper. . Therefore, when the screw 43 is tightened, it is possible to prevent the instrument mounting body 11 from being drawn into the wall hole Wa and to prevent deformation of the instrument mounting body 11.

  (5) When screws are tightened, the vicinity of the boss portion 18 where the screws are tightened is most attracted to the wall W side. And since the latching protrusion 17 was provided in the boss | hub part 18 vicinity, it can prevent that the boss | hub part 18 deform | transforms at the time of screw fastening with the latching protrusion 17. When the end of the locking projection 17 comes into contact with the rear surface of the instrument holding frame 40, the position of the instrument holding frame 40 can be appropriately changed to reflect the contact. It can suppress that the main body 12 and the instrument holding frame 40 are attached in the inclined state.

  (6) Further, the fact that the locking protrusion 17 abuts against the instrument holding frame 40 can be recognized that the screw 43 is difficult to be screwed in even if the screw is tightened further. It is possible to prevent the screws from being tightened.

  (7) The flange portions 21 were respectively formed on the right side wall 14c and the left side wall 14d that face each other in a direction orthogonal to the facing direction of the boss portion 18. According to this, since the formation position of the flange part 21 and the formation position of the boss | hub part 18 do not overlap, the flange part 21 can be formed largely. And by forming the flange part 21 large, the contact area of the flange part 21 with respect to the back of the wall W can be increased, and the wall member can be strongly held between the flange part 21 and the instrument holding frame 40. Further, by forming the flange portion 21 large, the flange portion 21 before displacement comes into contact with the front surface of the wall hole Wa even if the wall hole Wa is not precisely drilled according to the size of the mounting body main body 12. Therefore, since the accuracy of drilling is not required, work efficiency can be improved.

  (8) When the flange portion 21 is formed on the same peripheral wall as the boss portion 18, the boss portion 18 is also displaced along with the displacement of the flange portion 21, and there is a possibility that screw tightening cannot be performed at a correct position. However, since the flange portion 21 is formed on the right side wall 14c and the left side wall 14d facing each other in a direction orthogonal to the facing direction of the boss portion 18, the boss portion 18 is not displaced during screw tightening.

  (9) The flange portion 21 was extended to the vicinity of the boss portion 18 along the long side direction of the mounting body main body 12. Even if screws are tightened at either the upper or lower boss portion 18, only the upper or lower boss portion 18 is pulled to the wall W side because the flange portion 21 extends to the vicinity of the boss portion 18. In addition, the fixture mounting body 11 is supported by the locking protrusion 17 and the flange portion 21, and the fixture mounting body 11 can be prevented from entering the wall hole Wa.

  (10) When the instrument mounting body 11 is inserted into the wall hole Wa from the rear surface side of the mounting body main body 12, the guide is brought into sliding contact with the inner wall Wb of the wall hole Wa and the flange portion 21 is displaced to the inside of the mounting body main body 12. A portion 22 was provided. For this reason, the flange part 21 can be smoothly displaced by the guide part 22 at the same time as the instrument mounting body 11 is inserted into the wall hole Wa, and the entire instrument mounting body 11 is smoothly inserted into the wall hole Wa and the back of the wall W. can do.

(11) The guide portion 22 is formed by a ridge. For this reason, even if the guide part 22 is slidably contacted with the inner wall Wb of the wall hole Wa, the number of slidable contact parts can be reduced.
(12) Moreover, the fixture part 11 is inserted straight into the wall hole Wa from the rear surface side of the attachment body 12, and the flange part 21 is slidably contacted with the inner wall Wb of the wall hole Wa, whereby the flange part 21 is attached to the body body. 12, the entire instrument mounting body 11 was inserted into the wall hole Wa and the back of the wall W. Then, after the fixture mounting body 11 passes through the wall hole Wa, the flange portion 21 does not slide in contact with the inner wall Wb, so that the flange portion 21 returns to the state before being displaced behind the wall W (original position). Become. The flange attachment 21 was brought into contact with the back of the wall W, and the fixture member 11 was installed on the back of the wall W by sandwiching the wall material between the flange 21 and the appliance holding frame 40. According to such a method, the entire device mounting body 11 can be easily inserted into the wall hole Wa and the back of the wall W by using the elastic deformation force of the right side wall 14c and the left side wall 14d. The body 11 can be easily installed behind the wall W.

  (13) Since the instrument mounting body 11 is supported by the cable C by inserting the cable C through the cable insertion hole 16, the instrument mounting body 11 does not fall off the back of the wall W. Moreover, since the fixture mounting body 11 is supported by the cable C, when the cable C is connected to the wiring fixture H, it is not necessary to hold the fixture mounting body 11.

  (14) On the wall W surface, the fixture mounting body 11 is installed on the back of the wall W with the fixture holding frame 40 attached to the boss portion 18 with screws 43. According to this method, the work space is small and the work of assembling the cable fitting H to the fixture mounting body 11 and the cable connecting work can be performed on the wall surface, not on the back of the wall W that the worker cannot see. , Work becomes easier.

  (15) A hole Q is formed on the base end side of the right side wall 14c and the left side wall 14d. As a result, the right side wall 14c and the left side wall 14d are connected to the bottom wall 13 by the remaining side wall in which the hole Q is not formed, so that the right side wall 14c and the left side wall 14d are compared with the case in which the hole Q is not formed. The left side wall 14d can be easily elastically deformed. As a result, it becomes easy to displace the flange portion 21 integral with the right side wall 14c and the left side wall 14d.

  (16) The protrusion length T1 of the locking protrusion 17 is the same as the thickness N3 of the wall W. According to this, even if the wiring device H is pulled too much by tightening the screw 43, the end of the locking projection 17 and the wiring device H come into contact with each other, so that it is difficult to tighten the screw any more. , Excessive screw tightening can be prevented.

  (17) If the locking projection 17 that contacts the instrument holding frame 40 and the wall hole Wa is not formed, the instrument mounting body 11 may be pulled too far toward the wall W due to the tightening of screws. There is a possibility that the wall W may be damaged due to the force generated by the tightening. Therefore, the locking protrusion 17 is formed, and the protrusion length T1 of the locking protrusion 17 is the same as the thickness N3 of the wall W. According to this, even if the instrument holding frame 40 is pulled too much by tightening the screws 43, the end of the locking projection 17 and the instrument holding frame 40 come into contact with each other, so that excessive screw tightening can be avoided, As a result, damage to the wall W can be avoided.

In addition, you may change the said embodiment as follows.
In the embodiment, the hole Q may not be formed in the right side wall 14c and the left side wall 14d.
○ The number of the guide units 22 may be changed. For example, if one guides the insertion into the wall hole Wa, it is sufficient to form one. Moreover, the guide part 22 does not need to be formed.

  In the embodiment, regardless of whether the guide portion 22 is formed or not, the operator P himself / herself elastically deforms the right side wall 14c and the left side wall 14d to the inside of the mounting body main body 12 so that the entire instrument mounting body 11 is formed. May be inserted into the wall hole Wa and the back of the wall W.

  In the embodiment, the flange portion 21 may be formed only on either the right side wall 14c or the left side wall 14d. Moreover, you may form in at least any one among the upper side wall 14a and the lower side wall 14b. At this time, the contact surface 21a and the front surface of the boss portion 18 are located on the same plane. Further, when the flange portion 21 is formed on at least one of the upper side wall 14a and the lower side wall 14b, the locking protrusion 17 is assumed to extend from the contact surface 21a.

  In the embodiment, one of the pair of flange portions 21 may be displaceable to the outside and the inside of the attachment body 12, and the other flange portion 21 may not be elastically deformable. Incidentally, when using the fixture mounting body 11 having such a configuration, first, the contact surface 21a of the flange portion 21 that is not elastically deformed is hooked on the back of the wall W, and the hook flange portion 21 is used as the center of rotation. The attachment body 11 is rotated. Thereafter, the instrument mounting body 11 is pressed toward the back side of the wall hole Wa, the instrument mounting body 11 is inserted into the wall hole Wa, and the flange portion 21 that is elastically deformed is elastically formed inside the mounting body main body 12. The entire device mounting body 11 is inserted into the wall hole Wa and the back of the wall W. According to such a configuration, the operator can simply press the side wall with the flange portion 21, which can be elastically deformed, toward the inside of the attachment body main body 12, and the flange portion 21 is attached to the attachment body main body 12. The entire instrument mounting body 11 can be inserted into the wall hole Wa and the back of the wall W. That is, the instrument mounting body 11 can be deformed with less force than when both side walls are configured to be elastically deformable. Of course, it is also possible to use the guide portion 22 and insert it into the wall hole Wa and the back of the wall W. Further, the amount of tilting the attachment body 12 can be reduced as compared with the case where both side walls are formed so as not to be elastically deformable. Therefore, when both side walls are formed so as not to be elastically deformable, even if only a space that cannot be accommodated is formed on the back side of the wall W, one of the side walls can be elastically deformed. If it is a body, even if only such a space is formed, it can be accommodated behind the wall W.

In the embodiment, the flange portion 21 may not extend to the vicinity of the boss portion 18.
○ The number of the locking protrusions 17 may be changed. In other words, the number is not limited to two because it suffices to be positioned inside the wall hole Wa and contact the rear surface of the instrument holding frame 40. However, in order to prevent the instrument mounting body 11 and the instrument holding frame 40 from being attached in a tilted state, a plurality of them is desirable.

○ The locking protrusion 17 may be deleted.
The locking protrusion 17 may not be provided in the vicinity of the boss portion 18. That is, since it suffices to be located inside the wall hole Wa and contact the rear surface of the instrument holding frame 40, it may be provided at the inner end portion along the long side direction of the flange portion 21, for example.

Although the protrusion part of embodiment was the latching protrusion 17 formed in the front surface of the upper side wall 14a and the lower side wall 14b, it is good also as a protrusion part protrudingly provided so that the perimeter of the opening K might be enclosed.
In the embodiment, the instrument mounting body 11 is embodied as a type including a pair of upper and lower boss portions 18 and nuts as mounting portions, but two or more mounting portions are provided in the short side direction of the mounting body main body 12. You may change to type. Moreover, the formation position of the boss | hub part 18 is not restricted to the upper side wall 14a and the lower side wall 14b, You may form in the right side wall 14c and the left side wall 14d.

  ○ The thickness and material of the wall W used in the embodiment may be changed. In addition, when the wall material used in the embodiment is the thinnest thinnest wall material that can be used, the protrusion length T1 of the locking protrusion 17 is changed so as to correspond to the thickness of the wall material. do not have to. That is, in the thinnest wall material, if the damage of the wall material can be avoided by suppressing the tightening of the screws by the locking protrusions 17, the wall W thicker than the thinnest wall material is not likely to be damaged. It is not necessary to change the protruding amount of the locking projection piece 17 in accordance with the thickness of the wall, and the single locking projection piece 17 can correspond to the walls W of various thicknesses.

  In the embodiment, the instrument mounting body 11 may have any shape. For example, as shown in FIG. 9, a bottomed square box-shaped instrument mounting body 50 may be used. And in the instrument attachment body 50, the flange part 21 is formed so that it may extend toward the outward of the instrument attachment body 11 over the whole length direction of the right side wall 14c and the left side wall 14d. And length L8 of the flange part 21 along the long side direction of the instrument attachment body 11 in a modification is the same as the length L9 between the both ends of the boss | hub part 18 along the long side direction of the instrument attachment body 11. Thus, the flange portion 21 is extended to the vicinity of the boss portion 18 along the facing direction of the boss portion 18.

  In the case of such a shape, the wall hole Wa drilled in the wall W also has a rectangular shape. Moreover, the length along the long side direction of the wall hole Wa in the modified example is the same as the length L8 of the flange portion 21 along the long side direction of the instrument mounting body 11 in the modified example. Therefore, when the instrument mounting body 50 is inserted into the rectangular wall hole Wa from the rear surface side of the instrument mounting body 50 and the screw is screwed, the flange of the instrument mounting body 50 that has passed through the wall hole Wa. The abutment surface 21a of the portion 21 abuts over the entire length along the peripheral edge of the wall hole Wa, particularly the long side direction of the wall hole Wa. Thereby, it becomes difficult for force to be applied in a direction in which the instrument mounting body 50 enters the wall hole Wa.

(Circle) the wiring fixture attachment body in embodiment is good also as a frame shape in which a bottom wall is not formed.
In the embodiment, the instrument mounting body 11 is arranged on the back side of the wall W in a state where the instrument mounting body 11 and the instrument holding frame 40 are assembled by the screws 43 on the wall W surface. The assembling order of 40 may be any order. For example, the guide portion 22 is press-fitted on the inner wall Wb of the wall hole Wa to temporarily fix the device mounting body 11 in the wall hole Wa, and the device holding frame 40 is attached to the boss portion 18 with screws 43, and then the device is mounted. A method of installing the instrument mounting body 11 behind the wall W by inserting the body 11 further into the back side of the wall hole Wa may be used. According to such a method, since the instrument mounting body 11 is temporarily fixed in the wall hole Wa, it is not necessary to grip the instrument mounting body 11 when connecting the instrument holding frame 40 to the instrument mounting body 11. Expected to improve work efficiency.

Next, a technical idea that can be grasped from the above embodiment and another example will be added below.
