  Moreover, in this wiring fixture mounting body 10, the regulating portion 1 has an adjustment space A (FIGS. 3A and 3B) that allows angle adjustment between the inner surface of the wall hole and the wiring fixture mounting body 10 on both sides thereof. )) Is formed by narrow protrusions.

  Further, the wiring device mounting body 10 is characterized in that the regulating portion 1 is also provided at a position facing one side, and in this example, a pair is provided facing up and down.

  In addition, in the wiring fixture mounting body 10, the clamping part 4 is provided on one side or the one side and the side facing the one side, and the regulating part 1 is such that the clamping part 4 is against the wall hole. It is characterized in that it is restricted from being placed away from each other.

  In addition, the wiring fixture mounting body 10 includes a peripheral wall 6 that forms an opening 5 that opens on the wall surface on the inside. The wiring fixture mounting portion 2, the latching portion 3, and the clamping portion 4 are provided on the peripheral wall 6. The latch part 3 protrudes outward, and the restricting part 1 is provided on the outer surface of the peripheral wall 6.

  Hereinafter, in more detail, it demonstrates centering on the characteristic point about the structure and effect of this wiring fixture attachment body 10. FIG.

  First, as shown in FIG. 1 (a), the overall shape of the wiring device mounting body 10 is a little smaller than the oval wall hole WH (see FIG. 2) in which a semicircle and a semicircle are connected by a straight line. It is a box shape with an oval shape.

  The restricting portion 1 is configured as protrusions provided on the upper and lower sides of the oval peripheral wall 6 of the wiring fixture mounting body 10, but only one of them may be provided. Further, even when both are provided in this way, the distance between the tips of the restricting portions 1 is smaller than the space between the top and bottom of the oval wall hole WH, and one of the restricting portions 1 has the oval wall hole WH. When abutting against one of the circumferential walls, a gap is generated between the other restricting portion 1 and the other circumferential wall.

  The wiring device mounting part 2 is common to the normal wiring device mounting part 2 and is formed with a female screw hole having a conical opening end, so that the wiring device HK (see FIG. 4) can be attached with screws. It is like that.

  The latching portion 3 projects from the opening 5 of the peripheral wall 6 to the outside of the front peripheral edge portion of the wall hole. In this example, four places are provided on the front side of the oval peripheral wall 6, but the shape is not limited to this example, and the number may be at least two, and is not limited to four. Absent.

  Although not shown here, the clamping portion 4 is a clamping screw hole 4a through which the clamping screw 4b (see FIG. 3) passes, the clamping screw 4b, and a clamping screwed into the screw portion of the clamping screw 4b. A piece 4c (not shown; refer to FIG. 3) and a holding piece accommodating portion 4d for accommodating the holding piece 4c so as to be able to appear and retract are provided. Since the structure of this clamping part 4 is a well-known thing (for example, patent document 1), detailed description is abbreviate | omitted.

  On the back side of the oval peripheral wall 6 (on the opposite side of the opening 5), there is provided a bottom 7 that closes the opening to the back, and the bottom 7 is appropriately provided with a through-hole to the outside. A knockout portion 7a that can be removed manually at the site is provided at the center position. A tool insertion hole 7b, which is a cross-shaped through hole, is provided at the center position of the knockout portion 7a.

  The tool insertion hole 7b can be used as an index indicating the center position of the wiring fixture mounting body 10 by inserting the tip of the driver into the tool insertion hole 7b and removing the knockout portion 7. The bottom 7 is not necessarily required.

  On both end sides of the arc-shaped portion of the oval peripheral wall 6 on the opening 5 side, there are relief portions 6a in which a part of the peripheral wall 6 is cut out. In the vicinity of the escape portion 6a, the thickness of the peripheral wall 6 is also thin, and the escape portion 6a prevents the corresponding outer portion of the wiring device HK (see FIG. 4) attached to the wiring device attachment body 10 from hitting. ing.

  Hereafter, the usage and effect of the wiring fixture mounting body 10 of FIG. 1 will be described with reference to FIGS. FIG. 2 is a perspective view showing a state in which a wall hole is drilled with a punch for punching an oval wall hole. In addition, below, the part already demonstrated is attached | subjected the same code | symbol and duplication description is abbreviate | omitted.

  FIG. 3 (a) shows a wiring device in a state where the vertical center line of the wall hole and the vertical center of the wiring device mounting body of FIG. The figure which shows the state by which the attachment body was inserted in the wall hole, (b) is a figure which shows the state which made the vertical center line of the wiring fixture attachment body correspond to a perpendicular direction from the state of (a), and angle adjustment was completed. .

  FIG. 3C is a longitudinal sectional view of the BB in the state of FIG. 3B, and FIG. 3D is a longitudinal sectional view showing a state in which the clamping screw of the clamping part is rotated from the state of FIG. e) is a longitudinal sectional view showing a state in which the clamping and fixing by the clamping part and the latching part have been completed, and FIG. 4 shows that the installation of the wiring apparatus and the surface decorative panel is further completed from the state of FIG. It is a front view which shows the state which carried out.

  First, as shown in FIG. 2, for example, a wall hole WH is drilled with a wall hole punching tool 20 in a required portion of the wall W supported from the inside by a lightweight partition H. This wall hole punch 20 includes a level 11 and is detachably attached to the tip of the electric drill 30 for use.

  This wall hole punch 20 can open an oval shape in which semicircles are connected by a straight line, that is, a non-circular wall hole WH at one time, for example, as described in Japanese Patent Application Laid-Open No. 2000-103119. In addition, it can be opened by the level 11 so that the vertical direction of the oval wall hole WH becomes the vertical direction.

  However, even if it is relied on the level 11, the vertical direction of the oval wall hole WH may be inclined with respect to the vertical direction as shown in the figure, not in the vertical direction. As will be described below, the wiring fixture mounting body 10 of the present invention demonstrates its power.

  As shown in FIG. 3A, the inclination direction HC of the inclined wall hole WH after drilling and the center line (line connecting the centers of the pair of upper and lower wiring device mounting portions 2) BC of the wiring device mounting body 10 are defined. In a state of matching, the wiring fixture mounting body 10 is inserted into the wall hole WH. Since the peripheral wall 6 of the wiring fixture mounting body 10 has an oval shape that is slightly smaller than the wall hole WH, insertion is easy. The knockout portion 7a has already been removed to allow the wiring in the wall to pass therethrough, and a knockout hole 7c is formed.

  At this time, the wiring fixture mounting body 10 is provided with a restriction portion 1 projecting from the peripheral wall 6 up and down, and the lower restriction portion 1 abuts against the wall surface of the lower circumferential wall of the wall hole WH, and around it. An adjustment space A is formed. This is because the upper and lower restricting portions 1 and the upper and lower inner peripheral surfaces of the wall hole WH are smaller than the clearance provided over the entire circumference between the oval wall hole WH and the peripheral wall 6 of the wiring fixture mounting body 10. It also means that the gap between them is sufficiently small, and the upper and lower offsets of the wiring fixture mounting body 10 are smaller.

  Here, of the upper and lower restricting portions 1, the lower restricting portion 1 is in contact with the wall surface of the lower circumferential wall of the wall hole WH, but the upper restricting portion 1 is the upper circumferential wall of the wall hole WH. It does not come into contact with the wall surface.

  In other words, from the viewpoint of reducing the vertical deviation of the wiring fixture mounting body 10 with respect to the oval wall hole WH, it is sufficient that the restricting portion 1 has one place in one direction where the deviation is desired to be reduced. In that case, when using the wiring fixture mounting body 10, there is a complication that it is necessary to pay attention to the direction of use such as up and down. In this wiring fixture mounting body 10, a pair of restriction portions 1 are provided in the vertical direction. -ing

  Now, in the state of FIG. 3 (a), since the wiring fixture mounting body 10 remains inclined, the angle adjustment is performed so that the upper and lower center lines BC of the wiring fixture mounting body 10 are vertical with the lower regulating portion 1 as the center. FIG. 3B shows the state after the operation is completed, and the adjustment of the angle of the wiring fixture mounting body 10 is completed, and the state in which the vertical deviation is small is also maintained.

  Thereafter, as shown in FIGS. 3C and 3D, when the clamping screw 4 b is rotated clockwise in the clamping part 4, the clamping piece 4 c accommodated in the clamping piece accommodation part 4 d is separated from the peripheral wall 6. It co-rotates so that it protrudes, rises up and keeps its posture, gradually approaching the wall back rim direction of the wall hole WH, and as shown in FIG. 3 (e), the latching portion 3 and the sandwiching piece 4c The wall W at the peripheral portion of the wall hole WH is sandwiched between the wiring device mounting body 10 and the wall fixture WH in the vertical state in the wall hole WH.

  Thereafter, FIG. 4 shows a state in which the wiring fixture HK is attached to the wiring fixture mounting body 10 and the surface decorative panel KP is further installed. According to FIG. 4, in the case where the wall hole WH is inclined and a gap is provided so that the mounting angle of the wiring fixture mounting body 10 can be adjusted, the wiring fixture mounting body 10 is offset in the vertical direction and vertically. The wiring device HK and the surface decorative panel KP can be installed vertically and with little deviation on the top and bottom of the wall hole.

  That is, according to this wiring fixture mounting body 10, even when the directional wall hole WH is formed to be inclined with respect to the vertical direction, the wiring fixture HK can be attached in an appropriate vertical direction. The wiring fixture mounting body 10 can be attached to the wall hole evenly.

  In addition, the direction in which the restricting portion 1 is provided coincides with the direction in which the holding portion 4 is provided. In other words, the restricting portion 1 is configured so that the holding portion 4 of the wiring fixture mounting body 10 is vertically moved with respect to the wall hole WH. Since the restriction pieces 4c of the restriction portion 4 have the same contact area, the wall of the peripheral edge of the wall hole WH is sandwiched between the restriction portions 4 and the latch portion 3.

  Moreover, since the adjustment space A is formed around the restricting portion 1 with the wall hole WH, the angle can be adjusted. Even when the wiring fixture mounting body 10 is tilted to the maximum extent in the wall hole WH, the latching portion 3 is configured to clamp the wall together with the clamping portion 4, so that the lack of clamping does not occur.

  Moreover, such an oval-shaped wall hole WH is suitable for mounting a wiring apparatus provided with two or three switches, which is normally used, and therefore, for such a normally used wall hole, In particular, the wiring fixture mounting body 10 exhibits the above effects well.

  In addition, although the wiring fixture mounting body 10 illustrated the box-shaped thing here, the wiring fixture mounting body of this invention has a plate shape as described in patent document 2, the inside of a surrounding wall, a side wall part. Even those that are not present or in various forms are included as long as they can be provided with a restricting portion.

  Further, the tolerance of the vertical inclination of the directional non-circular wall hole opened by the wall hole punching tool is 5 degrees, and this wiring apparatus mounting body 10 is connected to the wiring apparatus mounting body 10 three times. By making the angle adjustable twice by attaching the appliance HK, the verticality of the wiring appliance HK is maintained as a whole.

Embodiment 2

  FIG. 5 shows a usage example of another example of the wiring fixture mounting body according to the present invention. (A) shows a rectangular wall hole whose vertical direction is inclined from the vertical direction, and the vertical center of the wall hole. The figure which shows the state by which the wiring fixture attachment body was inserted in the wall hole in the state which the upper and lower centers of the wiring fixture attachment body of another example corresponded, (b) is the upper and lower sides of a wiring fixture attachment body from the state of (a) It is a figure which shows the state which made the center line correspond to a perpendicular direction, and angle adjustment was completed.

  As shown in FIG. 5A, in this case, the wall hole WI has a rectangular shape, and its vertical center line HC is inclined as compared with the vertical direction. The wiring fixture mounting body 10A used for the rectangular wall hole WI has a rectangular shape that is slightly smaller than the whole wall hole WI.

  A pair of restricting portions 1A of the wiring fixture mounting body 10A are provided on the top and bottom of the wiring fixture mounting body 10A, and coincide with an arc CA (see FIG. 5B) that is the vertical and horizontal center of the wiring fixture mounting body 10A. And is in contact with both the upper and lower inner surfaces of the rectangular wall hole WI.

  According to the wiring fixture mounting body 10A provided with such a rectangular wall hole WI and the restricting portion 1A, as shown in FIG. The vertical direction of the body 10A can be matched with the vertical direction.

Embodiment 3

  6 (a) and 6 (b) are front views showing a usage example of another example of the wiring fixture mounting body of the present invention.

  In FIG. 6 (a), the wall hole WJ has a bowl shape in which a circular wall hole drilling tool is used, and the wiring fixture mounting body 10B has a shape corresponding thereto. The part 3A is also different from the wiring fixture mounting body 10 in FIG.

  Such a wiring fixture mounting body 10B also exhibits the same effect as the wiring fixture mounting body 10 of FIG.

  The thing of FIG.6 (b) is a thing in which the wall hole WK is a shape which put in parallel the bowl shape opened using the wall hole drilling tool for circular shapes, and the wiring fixture mounting body 10C also respond | corresponds to it. It differs in shape from the wiring fixture mounting body 10 of FIG. 1 in that the latching portion 3A also corresponds to its outer shape.

  Such a wiring fixture mounting body 10C also exhibits the same effect as the wiring fixture mounting body 10 of FIG.

  According to the wiring fixture mounting bodies 10 to 10C of the present invention, the angle can be adjusted within the directional non-circular wall hole as in the embodiment, and the wall hole slightly larger than the wiring fixture mounting body is not offset. Since it is attached to the wall hole by adjusting the angle, it is not always necessary to form an accurate wall hole, and the burden of angle adjustment at the time of drilling in the field is reduced.

  In addition, according to the wiring fixture mounting bodies 10 to 10C of the present invention, since the wiring fixture mounting body is relatively small with respect to the wall hole to be formed, it is easy to insert the clamping portion 4 into the wall hole. The angle can be adjusted inside, and the angle adjustment work can be concentrated by the deviation control by the restriction unit 1.

  In addition, even in the case of any of the above-described wiring fixture mounting bodies 10 to 10C, after inserting the wiring fixture mounting bodies 10 to 10C into the wall holes WH to WK and adjusting the mounting angle of the wiring fixture mounting bodies 10 to 10C, It is possible to realize a wiring device mounting method in which the wiring device mounting bodies 10 to 10C are mounted to the wall holes WH to WK by the sandwiching portion 4, and the effects of the wiring device mounting bodies 10 to 10C are It can be demonstrated as an attachment method.

  In addition, the wiring fixture attachment body and its attachment method of the present invention are not limited to the above-described embodiments, and various modifications and combinations are possible within the scope described in the claims and the scope of the embodiments. These modifications and combinations are also included in the scope of the right.

  In addition, when the wall hole is tilted, the wiring fixture mounting body and the mounting method of the present invention can adjust the angle as described above, and in a certain direction with respect to the wall hole of the mounting body (although the vertical direction is the main). Although the offset is reduced, of course, even when the wall hole is not inclined, it acts to reduce the offset in a fixed direction with respect to the wall hole of the mounting body.

  The wiring device mounting body and its mounting method according to the present invention are suitable when the wiring device is attached to a wall, and the wiring device is properly used even when the directional wall hole is inclined with respect to the vertical direction. It can be installed in a vertical direction, and can be used in an industrial field in which it is required that the wiring fixture mounting body be evenly attached to the wall hole.
