[0020]
Next, the cutting means will be described. The cutting means includes a cutting tool 10a shown by a two-dot chain line in FIG. 3 (a) and a drill bit 14 shown in a solid line in FIG. 3 (a) attached to the cutting tool 10a. It is configured. The drill bit 14 includes a rod-shaped bit shaft 15 made of a metal material. As shown in FIG. 3B, a cutting edge 15 a extending in a crescent cross section along the axial direction of the bit shaft 15 at the tip end side of the bit shaft 15 (the left end side in FIG. 3A), as shown in FIG. A post 15b extending substantially in a spindle shape in cross section is juxtaposed with a gap between them to form a resection blade portion 16. A non-removal portion 17 that covers the outer peripheral surface of the resection blade portion 16, that is, the distal end portions of the cutting blade 15 a and the post 15 b, is attached to the distal end portion.
[0021]
The base end of the bit shaft 15 (the right end in FIG. 3A) has a substantially cylindrical shape, and is provided with a shank 15c that can be attached to the tip of the cutting tool 10a. A cylindrical sleeve 18 that covers a part of the outer peripheral surface of the bit shaft 15 along the axial direction of the bit shaft 15 is mounted on the bit shaft 15, and the sleeve 18 is disposed in the axial direction of the bit shaft 15. It is provided movably along. A contact surface 18a that can contact the surface of the wall member 13 is formed on the outer end surface of the bit shaft 15 on the side of the cutting blade 16 among the outer end surfaces on both sides of the sleeve 18. Further, a threaded hole 18b is formed in the sleeve 18 through the wall of the sleeve 18, and a female screw (not shown) is threaded on an inner peripheral surface of the threaded hole 18b.
[0022]
By moving the sleeve 18 along the bit axis 15, the position of the sleeve 18 along the bit axis 15 is adjusted to adjust the distance between the abutment surface 18 a and the non-excised portion 17, that is, the exposure of the excision blade 16. The length is adjustable. Further, after the position of the sleeve 18 is adjusted, the set screw 18c is screwed into the screw hole 18b, and the tip of the set screw 18c is pressed against the outer surface of the shank 15c to position the sleeve 18 on the bit shaft 15. Is configured to be able to maintain the exposed length. Then, the drill bit 14 is attached to the cutting tool 10a, and by rotating the drill bit 14 with the cutting tool 10a, the cutting blade 16 is rotated to cut the wall material 13.
[0023]
Now, a method of attaching a wiring device to the wiring box 11 will be described.
First, as shown in FIG. 1, the wiring box 11 is mounted on the column 12 so that the front end surface of the peripheral wall and the front surface of the column 12 are flush with each other. It is pulled into the main body 19. Next, the wall material 13 is installed on the opening side of the wiring box 11, and the wiring box 11 is arranged on the back side of the wall material 13.
[0024]
Next, the position of the detection film 30 is detected by a metal detector (not shown) or the like, and the position of the opening of the wiring box 11 is assumed. Next, a hole through which the drill bit 14 can pass is formed in the wall material 13 at an arbitrary position in the opening of the wiring box 11 from the front side using a drilling tool such as a drill or a drill. The distal end of the resection blade 16 may be made to protrude from the distal end surface of the non-resection 17 to form a hole through the wall material 13 with the resection blade 16.
[0025]
Subsequently, a ruler or the like is inserted into the hole, and the thickness of the wall material 13 is measured with the ruler. The position of the sleeve 18 is adjusted so that the thickness of the wall material 13 and the exposed length of the cutting blade 16 correspond to each other. adjust. After the position of the contact surface 18a is adjusted, the sleeve 18 is positioned on the bit shaft 15, and the shank 15c of the drill bit 14 is rotatably set on the tip of the cutting tool 10a.
[0026]
Next, the non-excised portion 17 and the excision blade portion 16 are inserted into the holes, and the wall material 13 is penetrated. Then, the contact surface 18a of the sleeve 18 comes into contact with the surface of the wall material 13, and the non-cut portion 17 penetrates the wall material 13 and protrudes to the back surface of the wall material 13, and is disposed in the wiring box 11. At the same time, the resection blade 16 is arranged such that the length of the exposed portion in the axial direction corresponds to the thickness of the wall material 13. Then, the drill bit 14 is rotated by the cutting tool 10a, and the drill bit 14 is moved toward the peripheral wall via the cutting tool 10a while the wall material 13 is cut by the cutting blade 16.
[0027]
Then, the non-excised portion 17 comes into contact with the inner surface of the peripheral wall, that is, the guide surface 25. At this time, the distal end surface of the wiring device mounting portion 28 is disposed at a position retracted from the guide surface 25 toward the bottom wall 20. Therefore, even if the cutting tool 10a is moved in the direction of the upper wall 21 or the lower wall 22 of the peripheral wall, the non-cutting part 17 does not come into contact with the wiring device mounting part 28, and the guide surface 25 of the upper wall 21 or the lower wall 22 does not come into contact. Contacted.
[0028]
Subsequently, the cutting tool 10a is moved along the direction in which the peripheral wall extends in a state where the non-cutting portion 17 is in contact with the guide surface 25. Then, the non-cutting portion 17 and the cutting blade 16 are guided by the guide surface 25 along the inner peripheral shape of the peripheral wall, and the wall material 13 is cut by the cutting blade 16 along the inner peripheral shape of the peripheral wall.
[0029]
At this time, since the passage is formed inside the guide surface 25, when the non-cut portion 17 is guided by the guide surface 25 of the upper wall 21 or the lower wall 22 and moves, the non-cut portion 17 is connected to the wiring device. There is no contact with the mounting part 28. Then, the cutting tool 10a and the drill bit 14 are guided over the guide surface 25 and are moved over the entire peripheral wall. As a result, as shown in FIG. 6, a through-hole that cuts off the wall material 13 along the inner peripheral shape of the peripheral wall of the box body 19 so that the opening of the box body 19 faces the front side of the wall material 13. 31 is drilled.
[0030]
Finally, the wiring device is held by a holding frame (not shown), and a mounting screw is screwed into the female screw portion 28b from both insertion holes of the holding frame, and the wiring device is mounted on the wiring box 11 via the holding frame. Further, a decorative plate for covering the opening of the wiring box 11 is attached to the surface of the wall material 13 with the wiring device facing the front side of the wall material 13.
[0031]
The effects exerted by the first embodiment will be described below.
A guide surface 25 is formed on the inner surface of the peripheral wall on the opening side of the box body 19 over the entire peripheral wall. Therefore, the cutting tool 10a and the drill bit 14 can be smoothly moved while being guided by the guide surface 25, and the wall material 13 can be reliably cut along the inner peripheral shape of the peripheral wall. Therefore, unlike the related art in which the position of the wiring tool attachment part 28 is confirmed and the cutting tool 10a and the drill bit 14 are moved while avoiding the wiring tool attachment part 28, the drilling work of the through hole 31 can be simplified. it can.
[0032]
Further, after the through-hole 31 is bored while leaving the wall material 13 located in front of the wiring device mounting portion 28, there is no need to cut the remaining portion, and the work of drilling the through-hole 31 is simplified. be able to.
[0033]
In addition, since the guide surface 25 is formed over the entire circumference of the peripheral wall, the non-removed portion 17 becomes the wiring device mounting portion 28 regardless of the direction in which the drill bit 14 penetrating the wall material 13 is moved. Can be brought into contact with the guide surface 25 without contact with the guide surface 25. Therefore, unlike the case where the perforation bit 14 is moved in consideration of the position of the wiring device mounting portion 28 to cause the non-excision portion 17 to abut on the guide surface 25, the work of perforating the through hole 31 can be performed quickly. .
[0034]
The wiring device mounting portion 28 is formed at a position where the front end surface is retracted from the front end surface of the peripheral wall. Therefore, the perforation bit 14 can be moved along the opening without disturbing the movement of the non-removed portion 17 along the guide surface 25 by the wiring instrument mounting portion 28, and the through-hole 31 along the opening can be reliably formed. Can be drilled.
[0035]
The wall material 13 can be cut by using the cutting tool 10a in which the piercing bit 14 is set. Therefore, unlike the related art in which the through hole 31 is manually drilled in the wall member 13 using a saw or the like, the operation of drilling the through hole 31 can be simplified and shortened.
[0036]
(2nd Embodiment)
Hereinafter, in each embodiment, the points different from the first embodiment will be mainly described.
[0037]
As shown in FIG. 7 and FIG. 8A, each wiring device mounting portion 28 is provided by a member different from the box main body 19. A through hole 32 is formed in the bottom wall 20 so as to penetrate the bottom wall 20, and a bearing 33 forming a rotation mechanism is formed on the upper surface of the bottom wall 20 at a position opposite to the through hole 32. Have been. Engaging projections 34 forming a rotating mechanism capable of engaging with the bearings 33 are protrudingly provided at opposing positions on the outer surface of the base end portion of each wiring instrument mounting portion 28. Each of the engaging projections 34 is engaged with the bearing 33, and the wiring device mounting portion 28 is rotatably mounted on the bottom wall 20 and provided on the box body 19.
[0038]
Further, a pair of projecting pieces 35 are protruded from the outer surface of each wiring device mounting portion 28, and a locking projection 35 a is protruded outward from the tip of each projecting piece 35. Each of the locking projections 35a is formed so as to be inclined outward from the distal end of the protruding piece 35 toward the base end. On the other hand, as shown in FIGS. 8A and 8B, the upper side wall 21 and the lower side wall 22 are formed with a locking hole 36 through which the pair of projecting pieces 35 can be elastically deformed so as to approach each other. Have been.
[0039]
Then, when the wiring device mounting portion 28 at the position shown by the solid line in FIG. 8A is rotated to the position shown by the two-dot chain line, each protruding piece 35 passes through the locking hole 36, and thereafter, as shown in FIG. As shown in (b), the locking projection 35a is configured to be lockable on the outer surface of the upper wall 21 or the outer surface of the lower wall 22. In the locked state, the rotation of the wiring device mounting portion 28 toward the bottom wall 20 is regulated, and the front end surface of each wiring device mounting portion 28 is almost the same as the front end surface of the peripheral wall on the opening side of the box body 19. Placed in
[0040]
The outer surface of a part of the base end of the wiring device mounting portion 28 and the upper surface of the bottom wall 20 are integrally formed, and the connecting portion is formed thin to form a hinge as a rotating mechanism. The wiring device mounting portion 28 may be provided so as to be rotatable up and down around the hinge as a rotation center, and a hinge as a rotation mechanism may be provided instead of the hinge.
[0041]
Now, in a state where the wiring box 11 of the second embodiment is mounted on the pillar 12, each wiring device mounting portion 28 is rotated toward the bottom wall 20 to dispose the distal end side at a position away from the guide surface 25. . Thereafter, the wall material 13 is installed in front of the wiring box 11.
[0042]
Next, a through hole 31 is formed in the wall material 13. At this time, since each wiring device mounting portion 28 is pivoted toward the bottom wall 20 side, a guide surface 25 is formed on the inner surface of the peripheral wall on the opening side of the box body 19 over the entire peripheral wall. A passage through which the non-excised portion 17 can pass is formed inside the surface 25. Therefore, the wall material 13 can be cut off by the cutting blade 16 by moving the non-cutting portion 17 along the guide surface 25 without contacting the wiring device mounting portion 28, and the through hole 31 along the opening can be reliably formed. And it can be easily drilled.
[0043]
After the through holes 31 are formed, the wiring device mounting portions 28 are turned to the opening side, so that the mounting holes 28 a are arranged on the opening side of the box body 19. As a result, since the mounting hole 28a faces the opening side of the box body 19, the length of the mounting screw in the axial direction is smaller than when the mounting hole 28a is retracted from the opening toward the bottom wall 20. It can be shortened, and the screwing work of the mounting screw can be performed in a short time. In addition, the locking of the wiring projection mounting portion 28 toward the bottom wall 20 is restricted by the locking of the locking projection 35a to each of the side walls 21 and 22, and the displacement of the mounting hole 28a can be prevented. Accordingly, the work of screwing the mounting screw into the female screw portion 28b can be simplified, and the work of mounting the wiring device to the wiring box 11 can be performed quickly.
[0044]

Is done. The distal end surface of the wiring device mounting portion 28, that is, the mounting hole 28a is disposed at substantially the same position as the front end surface of the peripheral wall.
[0047]
Now, in a state where the wiring box 11 of the third embodiment is attached to the column 12, each of the housing portions 40 is housed in the receiving portion 39. Thereafter, the wall material 13 is installed in front of the wiring box 11.
[0048]
Next, a through hole 31 is formed in the wall material 13. At this time, since the housing portion 40 is housed in the receiving portion 39, the guide surface 25 is formed on the entire inner surface of the peripheral wall on the opening side of the box body 19, and the guide surface 25 is formed inside the guide surface 25. A passage through which the non-excised portion 17 can pass is formed. Therefore, the non-cut portion 17 can be moved along the guide surface 25 without contacting the housing portion 40 of the wiring device mounting portion 28, and the wall material 13 can be cut by the cut blade portion 16, and the transparent material along the opening can be cut. The hole 31 can be reliably and easily formed. Further, after the through-hole 31 is formed, the mounting hole 28a can be positioned on the opening side of the box main body 19 by moving and positioning each of the housing portions 40 to the projecting position.
[0049]
(Fourth embodiment)
