(First embodiment)
A first embodiment of the present invention will be described below with reference to FIGS.
As shown in FIG. 1, the instrument mounting frame 11 as the instrument mounting member is disposed on the back side of the wall W through the wall hole Wa drilled in the wall W in order to install the wiring instrument H on the wall W. Has been used. The wall hole Wa has a vertically long circular shape.

The instrument mounting frame 11 will be described.
As shown in FIG. 1, the thin plate-like frame body 12 constituting the instrument mounting frame 11 has a shape in which a part in the circumferential direction formed in an annular shape is cut away (in this embodiment, a length constituting a vertically long rectangular frame). The shape is formed by removing one side of the side), and includes a sandwiching piece 13 that is vertically opposed to each other, and a connecting piece 14 that connects one end of each sandwiching piece 13 to each other. An opening 15 surrounded by the pair of sandwiching pieces 13 and the connecting piece 14 is formed. The instrument mounting frame 11 is formed of a synthetic resin material.

  As shown in FIG. 3, the length L1 of the opening 15 in the long side direction is shorter than the length N1 of the wall hole Wa in the long side direction. The length L2 in the short side direction of the opening 15 is shorter than the length N2 in the short side direction of the wall hole Wa. Further, in the frame main body 12, the length T1 of the connecting piece 14 in the long side direction is longer than the length N1 of the wall hole Wa in the long side direction, and the frame main body 12 has a length T1 in the long side direction. The length T2 is the same as the opening width of the wall hole Wa, that is, the length N2 in the short side direction.

The surface of the frame body 12 excluding the opening 15 is an abutting surface 12a that abuts against the peripheral edge of the wall hole Wa from the back side of the wall W.
As shown in FIGS. 1 and 2B, a pair of locking projections 17 each having a thin plate shape are provided on the surface of each clamping piece 13, that is, the same surface as the contact surface 12a. Each locking projection 17 is elastically deformable. A claw piece 17 a is formed at the tip of each locking projection 17 so as to be pointed toward the outside of the frame body 12.

  Further, on the surface of each sandwiching piece 13, a first regulating projection 18 a having a thin plate shape extending along the long side direction of the sandwiching piece 13 is provided between the pair of locking projections 17. . In addition, on the surface of each sandwiching piece 13, a pair of second restricting projections 18 b extending in the long side direction of the sandwiching piece 13 is provided on the outer side of the pair of locking projections 17. Has been.

  The locking protrusion 17 and the first and second restricting protrusions 18a and 18b formed on each sandwiching piece 13 are located on the same arc, and the arc is substantially the same shape as the arc of the wall hole Wa. And it is substantially the same length. Thus, when the locking protrusion 17 and the first and second restriction protrusions 18a and 18b are inserted into the wall hole Wa, the locking protrusion 17 and the first and second restriction protrusions 18a and 18b It is located inside the hole Wa.

  On the surface of each clamping piece 13, a screw hole 19 that penetrates the frame main body 12 in the thickness direction is located inward of the locking projection 17 and substantially at the center along the long side direction of the clamping piece 13. Is formed. A nut (not shown) is fitted into the screw hole 19 so as not to move in the thickness direction of the frame body 12, and a female screw is formed on the inner peripheral surface of the screw hole 19 by the nut. Therefore, in this embodiment, the attachment part is formed by the screw hole 19 and the nut.

  A guide piece 20 for confirming the contact state of the wiring device to the back of the wall W is directed toward the surface of the frame body 12 at the approximate center of the inner end along the long side direction of the connecting piece 14. The protrusion is formed. The protruding length of the guide piece 20 is shorter than the thickness of the wall hole Wa, and when the instrument mounting frame 11 passes through the wall hole Wa and comes into contact with the back of the wall W, the guide piece 20 is moved to the wall hole Wa. Is visible from the front side of the wall W.

  Further, as shown in FIG. 4, the cable C is connected to the back side of each clamping piece 13 that is also the opposite surface of the contact surface 12 a and on the long side end portion of the clamping piece 13 that is located on the opposite side of the opening 15. Is inserted, or a holding portion 30 as a cable insertion portion for holding the conduit D through which the cable C is routed is provided so as to protrude outward of the frame body 12. The electric conduit D is a corrugated tube. The conduit D includes a small-diameter conduit and a large-diameter conduit having an outer diameter larger than that of the small-diameter conduit. Further, the holding portion 30 is located outward from the screw hole 19 so as to avoid the screw hole 19 formed in the instrument mounting frame 11, and a screw 43 inserted through the screw hole 19 is provided. Even if it protrudes from the back surface of the frame body 12, it does not interfere with the conduit D held by the holding portion 30.

  As shown in FIG. 2A, the holding portion 30 is formed to form a belt-like ring (endless ring) surrounded by the peripheral wall 31 without opening. The peripheral wall 31 does not include the frame main body 12, and the holding unit 30 is configured by the peripheral wall 31 and the frame main body 12. More specifically, the holding unit 30 is integrally formed with the frame body 12 with the back surface of the frame body 12 as a part of the holding unit 30. Further, the peripheral wall 31 is configured by opposed side walls 32 extending from the frame main body 12 toward the outside of the frame main body 12, and a connecting wall 33 connecting the free ends of the side walls 32. In addition, the inside of the holding unit 30 surrounded by the peripheral wall 31 is an internal space.

  Further, the side wall 32 includes an elastically deformable bellows portion formed in a bellows shape by alternately changing the folding direction, or an elastic portion 34 as a deformable portion. The side walls 32 are alternately folded so that the elastic portion 34 extends in a direction perpendicular to the long side of the sandwiching piece 13 (backward direction) so that the holding portion 30 is elastic. Will be provided. In addition, since the elastic portions 34 are formed over the entire opposing side walls 32, the elastic portions 34 are provided at opposing locations on the side walls 32. Since the elastic portion 34 is bent by folding the side wall 32 into a bellows shape, the elastic portion 34 is also a bellows bent portion.

  Moreover, as shown to Fig.2 (a), the inner surface of the connection wall 33 and the back surface of the frame main body 12 which opposes this inner surface are latched to the outer surface of the conduit D, and it is to the axial direction of the conduit D. A pair of locking pieces 35 for restricting the movement are provided facing each other. In addition, the locking piece 35 is provided at another opposing location orthogonal to the opposing location of the elastic portion 34 on the inner surface of the holding portion 30. The locking piece 35 is formed in the back along the insertion direction of the conduit D. Moreover, since the locking piece 35 is provided in the connection wall 33, the opposing space | interval of the locking piece 35 will spread by extending the elastic part 34. FIG.

  Further, since the side wall 32 includes an elastic portion 34 formed in a bellows shape, the internal diameter of the holding portion 30 (hereinafter referred to as an inner diameter) can be changed in a plurality of stages by expanding and contracting the elastic portion 34. Has been. The inner diameter of the holding portion 30 is the length between the opposing locking pieces 35. Moreover, when the internal diameter of the holding | maintenance part 30 changes in multiple steps, the internal space area of the holding | maintenance part 30 enclosed by the surrounding wall 31 also changes in multiple steps.

  Specifically, as shown in FIG. 2A, the state where the elastic portion 34 is folded is the initial stage, and the state where the elastic portion 34 is most extended toward the outside of the frame body 12 is the final stage. It becomes. The inner diameter R1 of the holding portion 30 in the initial stage is smaller than the outer diameter of the small diameter conduit. On the other hand, the inner diameter R2 of the holding portion 30 in the final stage is slightly larger than the outer diameter of the large diameter conduit so that the large diameter conduit having a larger outer diameter than the small diameter conduit can be retained. The circumferential length is set. That is, since the inner diameter of the holding part 30 and the area of the inner space of the holding part 30 can be changed by expanding and contracting the elastic part 34, two or more types of conduit tubes having different outer diameters are provided inside the holding part 30. And can be held in pressure contact with the elastic force of the elastic portion 34. Note that the inner diameter R2 of the holding portion 30 in the final stage is shorter than the depth of a space (not shown) formed between the two standing walls W. Thereby, even if the holding | maintenance part 30 is extended to the outer side of the frame main body 12 to the maximum, it does not contact | abut to the wall W located in the back surface among the two walls W with which the holding | maintenance part 30 was erected.

  Further, as shown in FIG. 2A, the folding interval Q1 of the elastic portion 34 in the initial stage is formed to a length that can be held by sandwiching the cable C from the thickness direction by the opposing side wall 32. . That is, the folding interval Q <b> 1 of the elastic portion 34 between the portion bent to the outside of the ring and the portion bent to the inside of the ring has a width smaller than the thickness of the cable C. Thereby, the location corresponding to the folding interval Q1 of the elastic portion 34 functions as a holding portion 36 that holds the cable C by forcibly press-fitting the cable C.

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 a vertically long rectangular instrument holding hole 41 is formed inside the instrument holding frame 40. The length M1 in the long side direction of the instrument holding frame 40 is longer than the length N1 in the long side direction of the wall hole Wa. On the other hand, the length M2 of the instrument holding frame 40 in the short side direction is shorter than the length N2 of the wall hole Wa in the short side direction. 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 frame 11 is demonstrated according to FIG.4 and FIG.5 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, and the cable C is wired in the conduit D. Further, the extra length of the cable C is drawn from the conduit D.

  First, a wall hole Wa is drilled at a desired position of the wall W using an electric punch, and an extra length portion of the 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 worker P inserts the cable C drawn out on the surface of the wall W into the holding unit 30, holds it with the holding unit 36 formed inside the holding unit 30, and further connects the cable C to the wiring device H. .

  By forming the holding portion 30 in the instrument mounting frame 11 having an opening on one side, the cable C drawn from the back of the wall W can be inserted into the holding portion 30 and further held by the holding portion 36. Thereby, even if the instrument mounting frame 11 is arranged on the back of the wall W, it is possible to prevent the instrument mounting frame 11 from falling off the back of the wall W. In addition, since the cable C can be held in the vicinity of the wiring device H until the cable C is connected to the wiring device H, the work of attaching the cable C to the wiring device H is facilitated.

  Next, as shown in FIG. 4, the wiring device H is held in the device holding hole 41 of the device holding frame 40, and the screw 43 is inserted into the insertion hole 42 on the upper side of the device holding frame 40. Then, the screw 43 is inserted into the screw hole 19 on the upper side of the instrument mounting frame 11 and is screwed into the nut to temporarily fix the instrument mounting frame 11 and the instrument holding frame 40. Then, the instrument mounting frame 11 and the instrument holding frame 40 are connected to each other so as to be rotatable about the screw 43 as a rotation axis.

  Then, while the instrument holding frame 40 is disposed on the front side of the wall W, only the instrument mounting frame 11 is passed through the wall hole Wa. At this time, the instrument mounting frame 11 is rotated with the screw 43 as the center of rotation so that the opening edge of the wall hole Wa is positioned in the opening 15, and the instrument mounting frame 11 is passed through the wall hole Wa. Since the instrument mounting frame 11 has the opening 15, the opening edge of the wall W is positioned inside the opening 15 even when the wall W is thick or the interval between the walls W is narrow. By inserting the frame main body 12 into the wall hole Wa of the wall W while rotating, the wall hole Wa of the wall W can be easily passed through and can be easily disposed on the back side of the wall W.

  In addition, a holding portion 30 that protrudes outward from the frame main body 12, that is, in a direction perpendicular to the short side direction of the appliance mounting frame 11, is provided on the back surface of the appliance mounting frame 11. Part 34 is provided. For this reason, even when the instrument mounting frame 11 abuts against the surface of the wall W when passing the instrument mounting frame 11 through the wall hole Wa, the elastic portion 34 is pressed against the wall W as shown in FIG. Thereby, the holding part 30 is compressed and deformed, and the protruding amount of the holding part 30 is reduced. Thus, by making the holding | maintenance part 30 elastically deformable, when the instrument mounting frame 11 passes the wall hole Wa, it does not become obstructive. In addition, the holding portion 30 through which the cable C and the conduit D are not inserted does not get in the way when the instrument mounting frame 11 passes through the wall hole Wa because the protruding amount is reduced by the elastic deformation of the elastic portion 34. .

  Next, the worker P extends the holding portion 30 toward the outside of the frame body 12 and inserts the conduit D into the holding portion 30. Then, when the worker P stops the extending operation of the holding unit 30, the inner surface of the holding unit 30 presses the outer surface of the conduit D by the return force of the holding unit 30 to the initial stage. The conduit D is held. Further, when the locking piece 35 is locked to the outer surface of the conduit D, the movement of the conduit D in the axial direction is restricted. Further, since the conduit D is pressed and held by the inner surface of the holding portion 30, the connection state between the conduit and the holding portion 30 is not released by the weight of the instrument mounting frame 11.

  By providing the holding portion 30 with the elastic portion 34 formed in a bellows shape, the holding portion 30 can be expanded and contracted on the back surface of the frame body 12. And since the internal diameter of the holding | maintenance part 30 is expanded / contracted by expanding / contracting the elastic part 34, the multiple types of outer diameter conduit D can be hold | maintained with the one holding | maintenance part 30. FIG.

  Next, on the back side of the wall W, the locking protrusion 17 and the first and second restricting protrusions 18a and 18b are inserted into the wall hole Wa. Then, as shown in FIG. 3, the locking projection 17 and the first and second regulating projections 18 a and 18 b come into contact with the inner surface of the wall hole Wa, so that the instrument mounting frame 11 is positioned on the wall W. In this positioning state, the contact surface 12a corresponding to the clamping piece 13 contacts the upper and lower edges of the wall hole Wa, and the contact surface 12a corresponding to the connecting piece 14 is on the left edge of the wall hole Wa. It is in contact. Further, the opening 15 of the instrument mounting frame 11 faces the front side of the wall W from the wall hole Wa, and the screwing hole 19 faces the front side of the wall W from the wall hole Wa.

  Further, as shown in FIG. 5, each claw piece 17a of the upper locking projection 17 is bitten into the upper side surface W1 of the wall hole Wa and locked, and each claw of the lower locking projection 17 The piece 17a is bitten into the lower surface W2 of the wall hole Wa to be locked. Then, the instrument mounting frame 11 is restricted from falling to the back side of the wall W by the locking of the claw pieces 17a.

  Subsequently, the screw 43 screwed into the upper nut is further screwed into the instrument mounting frame 11. Further, the screw 43 is inserted into the lower insertion hole 42 of the instrument holding frame 40, and the screw 43 is screwed into the nut of the lower screw hole 19 of the instrument mounting frame 11. When both the screws 43 are tightened, the instrument holding frame 40 is drawn to the wall W as the screws 43 are screwed into the nuts, and the wall W is held between the instrument mounting frame 11 and the instrument holding frame 40. The 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 frame 11 is installed on the back side of the wall W with the device holding frame 40 interposed therebetween. . At this time, as shown in FIG. 5, the contact surface 12 a of the frame main body 12 contacts the peripheral portion of the wall hole Wa on the back surface of the wall W.

  At this time, since the guide piece 20 is visible from the front side of the wall W, the contact state of the instrument mounting frame 11 on the back of the wall W can be confirmed from the protruding amount of the guide piece 20 when visually observed. That is, when the guide piece 20 can be viewed vertically and parallel to the wall hole Wa, it can be confirmed that the instrument mounting frame 11 is disposed at a normal position behind the wall W. On the other hand, when the guide piece 20 cannot be viewed vertically or parallel to the wall hole Wa, it can be confirmed that the instrument mounting frame 11 is not disposed at a normal position behind the wall W.

According to the above embodiment, the following effects can be obtained.
(1) In the instrument mounting frame 11 having the annularly formed circumferentially cut frame body 12, one surface of the frame body 12 is a contact surface 12 a that abuts against the back of the wall W, and the frame body 12 is formed on the same surface as the contact surface 12a, while the frame body 12 is passed through the wall hole Wa while the cable C is inserted on the opposite surface of the contact surface 12a. The annular holding portion 30 that prevents the cable C from dropping off from the cable C behind the wall W of the frame main body 12 is provided in a projecting manner. According to this, a part of the instrument mounting frame 11 is notched, so that even if the instrument mounting frame 11 has the opening 15, the instrument mounting frame 11 is attached to the cable C by the annular configuration of the holding unit 30. Is supported. As a result, even if the fixture mounting frame 11 is arranged on the back of the wall W, the fixture mounting frame 11 does not fall on the back of the wall W, and the connection work of the cable C to the wiring fixture H and the installation work of the wiring fixture H are performed. Can be done smoothly.

  (2) The peripheral wall 31, more specifically, the side wall 32 has a bellows shape, so that the holding portion 30 is provided with elasticity. According to this, since the holding part 30 can be elastically deformed, the holding part 30 is easily deformed.

  (3) The peripheral wall 31 of the holding part 30, more specifically, the side wall 32 is formed in a bellows shape, and the inserted cable C can be sandwiched from the thickness direction by the folding interval Q1 (adjacent peripheral walls 31). According to this, since the cable C can be clamped by the clamping part 36 as a bent part in the holding part 30, the cable C can be further prevented from dropping off.

  (4) In the fixture mounting frame 11 provided with the holding portion 30 that is continuously formed in an annular shape so as to surround the circumferential direction of the conduit D, the peripheral wall 31 of the holding portion 30 is added to the peripheral wall 31 that forms the annular shape of the holding portion 30. The elastic portion 34 that is elastically deformable is provided so that the internal space that is surrounded by is expanded from the initial stage. Then, by deforming and expanding the elastic portion 34, the conduit D can be inserted into the internal space of the holding portion 30, and by returning to the initial stage, the inner surface of the peripheral wall 31 of the holding portion 30 on the outer surface of the conduit D Is pressed against the outer surface of the conduit D by the elastic restoring force to return to the conduit D inserted into the peripheral wall 31 so that the conduit D can be held. According to this, since the inner diameter of the holding part 30 can be changed only by extending, it can be held by the same holding part 30 regardless of the outer diameter of the conduit D used.

  (5) In order to enable the holding portion 30 to hold at least two types of outer diameter conduits D (small-diameter conduit and large-diameter conduit), a small-diameter conduit is inserted into the internal space of the retaining portion 30 in the initial stage. In addition to being a size that cannot be accommodated, it can be expanded to a size that allows insertion of large-diameter conduits. According to this, the conduit D inserted inside the holding part 30 can be held by the holding part 30 by the restoring force of the holding part 30 to the initial stage. In addition, by holding the conduit D with the holding unit 30, the conduit D is protected by the conduit D compared to when the cable C is pulled out and connected to the wiring device H without holding the conduit D with the holding unit 30. The amount of cable C that is not exposed is reduced.

  (6) Moreover, since it can hold | maintain with the same holding | maintenance part 30 irrespective of the outer diameter of the conduit D to be used, the holding | maintenance part 30 of the internal diameter suitable for the outer diameter of the conduit D to be used is formed separately. Even if it is not, as long as it is the range of the electric wire tube which can respond only by changing the holding | maintenance part 30, it can hold | maintain with one holding | maintenance part 30 all.

  (7) The inner diameter R1 of the holding portion 30 in the initial stage is formed smaller than the outer diameter of the small diameter conduit, but the elastic portion 34 allows the holding portion 30 to have a larger outer diameter than the small diameter conduit. The inner diameter was made expandable. Since the elastic portion 34 has an elastic force, the holding portion 30 can be easily expanded with a small force by the elastic force. Moreover, since the conduit D is hold | maintained when the restoring force after extending | stretching is added to the conduit D, the conduit D becomes difficult to drop out.

  (8) The elastic portion 34 has a bellows bent portion formed in a bellows shape on the peripheral wall 31. And the internal diameter R2 of the holding | maintenance part 30 in the state which extended the bent elastic part 34 was made larger than the outer diameter of a large diameter conduit tube. By forming the elastic portion 34, the length in the extending direction of the holding portion 30 is contracted by the amount bent by the elastic portion 34, so that the instrument mounting frame 11 itself is not bulky.

  (9) The holding part 30 expands the internal space of the holding part 30 by separating the opposing portions from each other. And the elastic part 34 was provided in the both-sides part (both side walls 32) substantially orthogonal to the location spaced apart in the holding | maintenance part 30. As shown in FIG. When the elastic portion 34 is provided at the opposite location, the force is applied evenly as compared to when the elastic portion 34 is provided at the non-opposed location, so that the holding portion 30 can be easily extended without applying too much force. Can do.

  (10) The elastic portion 34 can be elastically deformed in the direction in which the facing interval between the opposing locking pieces 35 is increased. According to this, since the position of the locking piece 35 is also displaced in accordance with the extension of the elastic portion 34, the outer diameter of the conduit D while maintaining the locking capability of the conduit D by the locking piece 35. Can also be retained.

  (11) A locking piece 35 that restricts the movement of the conduit D in the axial direction is provided inside the holding portion 30. Since the conduit D is locked by the locking piece 35 provided at the facing position, the conduit D is more difficult to drop off the holding portion 30.

  (12) From the front side of the wall W, in the instrument mounting frame 11 arranged on the back side of the wall W through the wall hole drilled in the wall W, the annular holding part 30 through which the cable C on the back side of the wall W is inserted The frame body 12 protrudes from the back surface. And in the circumferential direction of the holding | maintenance part 30, it provided in the elastic part 34 so that the protrusion amount of this holding | maintenance part 30 could be reduced. According to this, even when the instrument mounting frame 11 abuts against the wall W when the instrument mounting frame 11 is disposed on the back side of the wall W through the wall hole Wa from the front side of the wall W, the holding portion 30 is not elastic. Since it has 34, since the protrusion amount of the holding | maintenance part 30 reduces by deformation | transformation of the elastic part 34, the installation operation | work to the wall W back of the instrument attachment frame 11 can be performed smoothly. As a result, the cable C can be easily wired.

  (13) Since the protruding amount of the holding part 30 through which the cable C and the conduit D are not inserted is reduced due to the elastic deformation of the elastic part 34, the wall hole Wa is not formed even if there is a holding part 30 that is not used. It does not get in the way when the instrument mounting frame 11 passes.

  (14) The holding portion 30 is formed at a position avoiding the screw hole 19 on the back surface of the frame main body 12. According to this, even if the screw 43 inserted into the screw hole 19 protrudes from the back surface of the frame body 12, it does not interfere with the electric conduit D held by the holding portion 30, so that the screw 43 is screwed into the screw hole 19. It is possible to smoothly perform the attaching operation and the inserting operation of the conduit D to the holding unit 30.

  (15) The frame body 12 has a shape in which a part in the circumferential direction of the annular frame-shaped frame body 12 is cut out. Then, on the back surface of the frame main body 12, the holding portion 30 is protruded at a position avoiding the screw hole 19. Further, the holding portion 30 was formed by using the back surface of the frame body 12 as a part of the holding portion 30 and providing the elastic portion 34 at the remaining portion. According to this, since a part of the frame main body 12 forms the holding portion 30, the holding portion 30 is not dropped from the frame main body 12, and elastic deformation is performed while fixing the holding portion 30 to the frame main body 12. By doing, the installation operation | work to the wall W back of the instrument mounting frame 11 can be performed smoothly.

  (16) The holding portion 30 is constituted by the frame main body 12, the opposing side walls 32 extending from the frame main body 12 toward the outside of the frame main body 12, and the connecting walls 33 connecting the tips of the side walls 32. Configured. And the elastic part 34 was provided in the both side walls 32, respectively. Since both side walls 32 of the holding portion 30 do not directly abut against the wall W, the pressure generated when the instrument mounting frame 11 and the wall W abut can be easily dispersed from the elastic portions 34 formed on the side walls 32.

  (17) The instrument mounting frame 11 has a shape having the opening 15 by removing one side of the long sides constituting the vertically long rectangular frame. For this reason, by using the opening 15 of the frame main body 12, it is possible to easily perform the operation of passing the instrument mounting frame 11 through the wall hole Wa. As a result, the instrument mounting frame 11 can be easily placed on the back side of the wall W. Can be arranged.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS. 6 (a), (b), (c) and FIG. In the embodiment described below, the same components as those in the first embodiment described above are denoted by the same reference numerals, and the redundant description thereof is omitted or simplified.

  In the instrument mounting frame 100 of the present embodiment, as shown in FIGS. 6A and 6B, the long side end of the sandwiching piece 13 located on the opposite side of the opening 15 on the back surface of each sandwiching piece 13. Two holding parts 30 are provided on each part along the long side direction of the holding piece 13. Thereby, the instrument mounting frame 100 has the four holding | maintenance parts 30, and can hold | maintain at least any one of the cable C and the electric wire tube D in each holding | maintenance part 30. FIG.

  Next, a method of installing the wiring device H on the wall W using the device mounting frame 100 will be described with reference to FIG. In the present embodiment, the cable C is inserted directly into the holding unit 30 without using the conduit D.

  The worker P causes the cable C drawn out to the surface of the wall W to be clamped by a clamping unit 36 formed inside the holding unit 30. Then, the cable C is connected to the wiring device H. Moreover, since the fixture mounting frame 100 has a larger number of holding portions 30 than the fixture mounting frame 11, the probability that the holding portion 30 contacts the surface of the wall W when the fixture mounting frame 100 is passed through the wall hole Wa. Becomes higher. However, even if the number of the holding parts 30 increases because the elastic part 34 formed in the holding part 30 is elastically deformed, it does not get in the way when the instrument mounting frame 100 passes through the wall hole Wa.

Therefore, according to the said 2nd Embodiment, in addition to the effect similar to (1)-(17) of 1st Embodiment, the following effects can be acquired.
(18) In the instrument mounting frame 100, a total of four holding portions 30 are provided by projecting two holding portions 30 along the long side direction of each sandwiching piece 13 located on the back surface of the frame body 12. It was. Thus, since there are many holding | maintenance parts 30 compared with the instrument attachment frame 11, the probability that the holding | maintenance part 30 will contact | abut the surface of the wall W when passing the instrument attachment frame 100 through the wall hole Wa becomes high. However, even if the number of the holding parts 30 increases because the elastic part 34 formed in the holding part 30 is elastically deformed, it does not get in the way when the instrument mounting frame 100 passes through the wall hole Wa.

In addition, you may change each said embodiment as follows.
In each embodiment, the annular cable insertion part (holding part 30) forms a slit in the cable insertion part unless the cable C is easily detached from the cable insertion part due to the movement of the cable C in the radial direction. May be.

  In each embodiment, the holding portion 30 may be formed anywhere as long as the holding portion 30 and the screw hole 19 do not overlap. For example, the clamping piece 13 may be positioned inward of the screw hole 19.

  In each embodiment, the inner diameter R2 of the holding unit 30 in the final stage may be longer than the depth of the space formed between the two standing walls W. In this case, the substantial inner diameter R2 of the holding portion 30 in the final stage is slightly shorter than the depth of the space formed between the two walls W, and the substantial inner diameter R2 of the holding section 30 in the final stage. It becomes.

  In each embodiment, as long as the holding part 30 can be elastically deformed, the folding direction of the elastic part 34 may be any direction. For example, as shown in FIGS. 8A to 8C, the peripheral wall 31 may be alternately folded outward and inward along the axial direction of the conduit D, that is, the long side direction of the instrument mounting frame 100. .

  In each embodiment, the shape of the holding portion 30 may be any shape as long as it has an inner diameter that can hold at least the cable C. For example, as shown to Fig.9 (a), the perimeter except the connection part 37 connected with the back surface of the frame main body 12 among the surrounding walls 31 which comprise the holding | maintenance part 30 may be formed in bellows shape. . In this case, since the entire circumference is formed in a bellows shape, the inner diameter of the holding portion 30 changes following the outer diameter of the conduit D inserted into the holding portion 30. Moreover, the holding | maintenance part 30 should just be provided with elasticity, and it is not necessary to fold the surrounding wall 31 in a bellows shape. For example, as shown in FIG. 9B, the opening 37 and the holding part 30 having elasticity may be formed by using the connection part 37 as a base end and curving the peripheral wall 31 in a circular shape from the base end. In this case, it is desirable that the opening width of the opening 38 is shorter than the thickness of the cable C so that the cable C inserted into the holding portion 30 does not fall off. In addition, since the peripheral wall 31 is curved in a circular shape with the connecting portion 37 as a base end, the holding portion is extended by extending the free end side of the peripheral wall 31 toward the outside of the holding portion 30. The conduit D can be inserted into the 30.

  In each embodiment, the inner diameter R1 of the holding part 30 in the initial stage can be reduced by the elasticity of the elastic part 34, but the inner diameter R1 of the holding part 30 in the initial stage is not changed in the direction of further reduction. Also good. In this case, it can be realized by setting the inner diameter R1 of the holding portion 30 in the initial stage to a length that does not change further in the direction of further reduction due to the folding interval of the elastic portion 34 and the thickness of the peripheral wall 31.

  In each embodiment, as long as the elastic part 34 is formed by folding the side wall 32 into a bellows shape, the folding interval may be any length. For example, the folding interval may be longer than the thickness of the cable C.

  In each embodiment, the instrument mounting frames 11, 100 are made to deform the wall holes Wa by elastically deforming the instrument mounting frames 11, 100 using the force generated when the elastic portion 34 is pressed against the wall W. Made it out of the way when passing. As an example of this change, a holding part 30 that can be plastically deformed may be used. In this case, before passing the instrument mounting frames 11 and 100 through the wall hole Wa, the operator P reduces the protruding amount of the holding part 30 by folding the holding part 30, and when passing through the wall hole Wa, The operator P only has to extend the holding unit 30 outward of the frame body 12. Further, when the holding part 30 that can be plastically deformed is used, the worker P presses the holding part 30 so as to reduce the inner diameter of the holding part 30 instead of the return force of the holding part 30 to the initial stage. The conduit D is held inside the holding unit 30.

  As long as the cable C or the conduit D can be held in each embodiment, the holding unit 30 may be formed at any location. For example, it may be provided at the opening ends of both short sides of the sandwiching piece 13 or may be provided on the connecting piece 14. However, it is preferable to provide the holding portion 30 at a position where the insertion of the screw 43 into the screw hole 19 is not hindered.

  In each embodiment, although the elastic part 34 was formed in the location (side wall 32) which the holding | maintenance part 30 opposed, it does not need to be the position which opposed. Moreover, the elastic part 34 may be formed at one place. That is, the force generated when the instrument mounting frames 11 and 100 abut on the surface of the wall W is not transmitted to the instrument mounting frames 11 and 100 and may escape from the holding portion 30 to the outside.

In each embodiment, the holding unit 30 may be able to hold only one type of outer diameter conduit.
In each embodiment, the holding portion 30 may be formed on the back surface of the sandwiching piece 13 in which one of the pair of screw holes 19 is formed.
