Description

[Detailed Description of the Invention] This invention relates to a recessed outlet mounting device.

Conventionally, floor outlets have been installed as shown in FIGS. 1 and 2. In the figure, 1
1 is a metal outlet box embedded in the concrete layer 3 of the floor 2, 4 is a conduit connected to the outlet box 1, and 5 is a floor outlet. Floor outlet 5 has surface cover 6
and an outlet main body 8 which is pivotably supported on the surface cover 6 about a support shaft 7 so as to be freely protrusive and retractable. A torsion coil spring 9 is attached to the support shaft 7 to urge the outlet body 8 to protrude, and a slide piece 10 is attached to the surface cover 6 to lock the outlet body 8 in a retracted state. The outlet box 1 consists of a main body 1a and a cover flange 1b attached to the opening of the main body 1a. A surface cover 6 of the floor outlet 5 is placed in contact with the surface of the floor 2 and is fixed to a screw hole in the cover flange 1b of the outlet box 1 with two fixing screws 11. However, with this configuration in which the floor outlet 5 is screwed directly into the screw hole of the outlet box 1, there is no flexibility in the installation direction of the floor outlet 5, and it is possible to embed the outlet box 1 in the wrong direction. There are problems in that installation is impossible in some cases, and there are restrictions on changing the direction after installation.

Therefore, as shown in Figures 3 to 5,
Projecting wall 1 fixed to the surface cover 6 of the floor outlet 5
2 are integrally protruded and fixed using a fork-shaped fixing fitting 13. The fixing fitting 13 is tightened by a nut 14 screwed onto the fixing screw 11, so that one end engages with the base of the fixed projecting wall 12 of the front cover 6, and the vicinity of the other end engages with the inner edge of the cover flange 1b. . The fixing fitting 13 has a fin portion 1 that prevents the rotation of the nut 14.
3a on both sides, the nut 14 is pulled up by rotating the fixing screw 11, and the nut 14 is tightened. With such a configuration, a degree of freedom is obtained in the mounting direction of the floor outlet 5. However, since the movement of the fixture 13 is not restricted during construction, the fixture 13 will come off unless it is secured with a rubber band 15 or the like.
The disadvantage is that it is difficult to construct. In addition, the rubber band 15 was easily cut, which also made the construction troublesome. In addition, if the outlet box 1 is buried deep, the fixing metal fitting 5 will not reach, so a small piece 16 for changing the fulcrum is inserted as shown in Fig. 6, but this small piece 16 is placed separately at the construction site. It was inconvenient because I had to prepare in advance.

Therefore, the purpose of this invention is to provide flexibility in the installation direction of the outlet, to make the installation easier since the fixing metal fittings will not come off during construction, and to reduce the embedding depth of the outlet box. To provide an embedded type outlet mounting device which can be fixed without using other parts even if it is deep.

An embodiment of this invention is shown in FIGS. 7 to 10. Note that the same parts as those in FIGS. 1 and 2 are given the same reference numerals, and the explanation thereof will be omitted. That is, to explain the different parts, a pair of fixed projecting walls 17 are located on both sides of the outlet main body 8 and integrally protrude from the back surface of the front cover 6 of the floor outlet 5. The fixed projecting wall 17 has a groove 18 along the height direction in the center of the outer surface, and a plurality of engagement recesses 19 are arranged in parallel in the height direction on both sides of the groove 18. In addition, a fixed projecting wall 17 is provided on the surface cover 6.
The insertion hole 20 for the fixing screw 11 is located slightly outside of the
is provided. Reference numeral 21 denotes a fixing metal fitting, which is formed into a fork shape that fits into the fixing screw 11. The fixing fitting 21 has a pair of engagement pieces 21a on the continuous side portion that fit into the left and right engagement recesses 19 of the fixed projecting wall 17, and nuts 22 at the lower part of both side edges.
A fin portion 21b for preventing rotation and increasing weight is formed by bending. The fixing fittings 21 are fixed projecting walls 17
It is formed to a width that fits into the groove 18 of. The nut 22 is formed into a rectangular shape large enough to be inserted between the fins 21b of the fixing metal fitting 21, and has a projection 22a on its upper surface for touching the fins 21b.

With this configuration, the floor outlet 5 can be installed in the following manner.
That is, the engagement protrusion 21a of the mounting bracket 21 is inserted into the engagement recess 19 of the fixed projecting wall 17 of the front cover 6, and the fin 21b of the attachment bracket 21 is fitted into the groove 18. Then, the fixing screw 11 is inserted into the insertion hole 20 of the front cover 6, and the nut 22 is screwed onto the tip of the fixing screw 11. At this time, the nut 22 is screwed in until the protrusion 22a hits the fin 21b of the fixture 21. In this state, the floor outlet 5 is inserted into the outlet box 1 (FIG. 9A). Next, when the fixing screw 11 is turned, the nut 22 is pulled up as the fixing screw 11 is rotated because the nut 22 is prevented from rotating by the fixing fitting 21. Therefore, the fixing bracket 2
1 is lifted up by the nut 22 and gradually changes its tilted posture, and the lower end portion of the fixing member 21 engages with the inner edge of the cover flange 1b of the outlet box 1. Therefore, the floor outlet 5 is fixed to the outlet box 1.

In this way, the floor outlet 5 is installed.Since the fixing fittings 21 are engaged with the cover flange 1b of the outlet box 1 to fix it, the floor outlet 5 can be installed in the same manner as the conventional one shown in FIG. A slight degree of freedom is obtained in the mounting direction of the floor outlet 5, and if the outlet box 1 is square, the mounting direction of the floor outlet 5 can be changed by 90 degrees. In addition, regarding installation work,
Since the engagement piece 21a of the fixture 21 is fitted into the engagement recess 19 of the fixed projecting wall 17 of the front cover 6 and the movement of the fixture 21 is restricted, there is no need to stop the fixture 21 with a rubber band or the like. Easy to construct.
Furthermore, the engagement piece 21a of the fixture 21 can be fitted into the engagement recess 19 of the fixed projecting wall 17 at an arbitrary height depending on the depth of embedding the outlet box 1, so that the fulcrum can be used as in the conventional case. Change piece 1
6 (Fig. 6) is no longer necessary.
Construction becomes easier.

In addition, if the embedding depth is extremely deep, by fitting the additional fixing piece 23 shown in FIG. . This additional fixing piece 23 is
It has protrusions 23a that fit into the engagement recesses 19 of the fixed projecting wall 17 of the surface cover 6 on both sides of the upper part, and has grooves 18' and engaging recesses 19' similar to those of the fixed projecting wall 17 in the lower part. be.

Although the above embodiment has been described with respect to a floor outlet, this invention can also be applied to an outlet embedded in a wall surface, a pillar, or the like.

As described above, the recessed outlet mounting device of this invention has a fixed protruding wall on the back side of the front cover of the outlet, a groove in the height direction on the outer surface of the fixed protruding wall, and a groove on both sides of this groove. A plurality of engagement recesses are arranged in parallel in the height direction on the side surface, and a fixing fitting that is tightened with a fixing screw and a nut to fix the outlet box and the surface cover is engaged with the engagement recess of the fixed projecting wall. Since it is equipped with an engaging piece that fits, there is a degree of freedom in the direction in which the outlet is installed, and there is no problem of the fixing fittings falling off during installation, making installation easier. Even when the depth is deep, there is an effect that fixation can be performed without using other parts.
