Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embedded lighting fixture mounting structure using a spring plate mounting bracket for fixing a main body of a fixture embedded in an embedded hole on a ceiling surface to a ceiling material on the ceiling surface. It is a thing.

[0003]

In the conventional mounting bracket of this type, it is difficult to remove the instrument body, and the mounting bracket may not be reused due to the deformation accompanying the removal. An object of the present invention is to provide an embedded luminaire mounting structure that can be easily removed and reused.

[0004]

SUMMARY OF THE INVENTION In the present invention, there is provided an instrument main body to be embedded in an embedding hole on a ceiling surface, and a spring plate mounting metal fitting for fixing the instrument main body to a ceiling material on the ceiling surface. The instrument body is provided with a slit extending in the vertical direction. The mounting bracket is a wide tension plate located outside the instrument body, a narrow upper narrow plate extending from the upper center of the tension plate through the slit, and an instrument further extending from the upper narrow plate. A wide upper wide plate located inside the main body is provided. Also, a narrow lower narrow plate that extends from the strut plate through the slit, a wide lower wide plate that extends from the end of the lower narrow plate and is located inside the instrument body, and a lower wide plate. A pressing plate further extending toward the upper wide plate is provided. Under the mounting condition, the lower part of the strut plate is brought into contact with the upper side of the ceiling material, and the biting edges on both sides of the upper part of the strut plate are bite obliquely upward to the outer surface of the instrument body. Further, the upper part of the pressing plate is slidably and elastically pressed against the inside of the instrument body so as to strengthen the bite. On the other hand, a gap is provided between the upper wide plate and the inner surface of the device body to release the bite against the elasticity of the holding plate, and the lower wide plate is attached to the inner surface of the device body to prevent the tension plate from rotating. Abut.

[0005]

[Function] The lower part of the tension plate is brought into contact with the upper side of the ceiling surface, and the biting edge of the upper part of the tension plate is bite obliquely upward to the outer surface of the instrument body. As a result, the load of the instrument body is transmitted to the ceiling material via the tension plate to support the instrument body. The upper part of the holding plate is slidably and elastically pressed against the inner surface of the instrument body.
As a result, the upper part of the tension plate is pulled to strengthen the bite. Provide a gap between the upper wide plate and the inner surface of the instrument body. By appropriately moving the upper wide plate by the amount of this gap against the elastic force of the holding plate, the upper part of the tension plate is also separated toward the outer side of the instrument body, and the bite is eliminated. The reason why the holding plate and the inner surface of the instrument body are slidable is to prevent the pressing plate from biting in this case and to allow the instrument body to descend with respect to the mounting bracket. The lower wide plate contacts the inner surface of the plate instrument body. This prevents the bracing plate from rotating so that it approaches the horizontal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The illustrated embodiments will be described below. In the present invention, the instrument body 10 embedded in the embedding hole in the ceiling surface
Equipped with 0. In addition, the fixture body 100 is used as the ceiling material 3 for the ceiling surface.
A fitting 200 made of a spring plate for fixing to 00 is provided. The instrument body 100 is provided with a slit 122 extending in the vertical direction. The fixture main body 100 corresponds to, for example, a case of an incandescent lamp downlight, and is provided with a square tube or a cylindrical tube body 120 having a flange 110 on the lower outer edge and a top plate 130 for closing the top surface thereof, and a light source (not shown) is provided inside. Accommodate. The slit 12
2 is formed in the cylindrical body 120. On the other hand, the mounting bracket 200 is a wide tension plate 2 located outside the instrument body 100.
10 and the slit 12 from the upper center of the tension plate 210.
The upper narrow plate 220 having a narrow width extending through the second narrow plate 220 and the wide upper narrow plate 230 further extending from the upper narrow plate 220 and located inside the instrument body 100. Further, a narrow lower narrow plate 240 extending from the strut plate 210 through the slit 122, and a wide lower narrow plate 2 extending from the lower narrow plate 240 and located inside the instrument body 100.
50 and a holding plate 260 that further extends from the lower wide plate 250 toward the upper narrow plate 220. As shown in FIG. 2, the lower portion of the tension plate 210 is brought into contact with the upper side of the ceiling material 300, and the sharp biting edges 212 formed on both sides of the upper portion of the tension plate 210 are diagonally upwardly bited into the outer surface of the instrument body 100. In this state, the tension plate 210 is inclined and the load of the instrument body 100 is transmitted to the ceiling material 300.
Support 00. The biting edge 212 may be a mere cut edge and need not be sharpened. Two sets or two or more sets of the slits 122 and the mounting brackets 200 corresponding to the slits 122 are formed in one instrument main body 100, but this point is the same as the conventional one, and therefore one set will be described here. The upper portion of the pressing plate 260 is slidably and elastically pressed against the inner surface of the instrument body 100 so as to strengthen the bite. The curved surface 262 on the upper part of the holding plate 260 is pressed against the inner surface of the device body 100, and the reaction force pulls the upper part of the tension plate 210 toward the device body 100 side to strengthen the bite.
On the other hand, a gap 232 is provided between the upper wide plate 230 and the inner surface of the instrument body 100 to cancel the bite against the elasticity of the holding plate 260. Further, the lower wide plate 250 is stretched so that the rotation of the plate 210 is prevented and the device main body 100 is prevented.
Contact the inner surface. FIG. 2 shows a state in which the instrument body 100 is attached. The mounting bracket 200 is mounted such that the slit 122, the upper narrow plate 220, and the lower narrow plate 240 correspond to each other from a wide portion (not shown) on the upper portion of the slit 122 of the instrument body 100. This mounting is performed before or after the instrument body 100 is placed on the ceiling surface. In the case of mounting before placement, the instrument main body 100 with the mounting bracket 200 is shown in FIG.
Place it on the ceiling as shown in. In FIG. 4, the mounting bracket 20
The tension plate 210 of 0 is in a substantially upright state, and in this state, there is no above-mentioned bite, and it dives into the embedding hole of the ceiling material 300 together with the instrument body 100. Then, for example, a finger is put on the lower wide plate 250 and pushed down as shown in FIG. 2 to lower the mounting bracket 200, and the lower portion of the tension plate 210 is fixed to the ceiling member 30.
Press firmly to 0. The contacting portion is, for example, a field edge of the ceiling material 300, but if the beam 310 of FIG. 3 is located there, it may be applied to the inside of the beam 310 as shown in FIG. In the situation of FIG. 2, the tension plate 210 is the ceiling material 30.
It is pushed to 0 and tries to rotate clockwise as shown. The rotation is blocked by the lower wide plate 250 hitting the inner surface of the instrument body 100. At the same time, the lower wide plate 250 serves as a fulcrum to strengthen the bite. This bite is also strengthened by the pressure contact of the upper part of the pressing plate 260. Presser plate 260
The upper pressure contact also acts to induce the first bite. In addition, the latter pressure contact acts so that the bite does not come off even when vibration is applied to the instrument body 100. At the time of releasing the bite, the upper wide plate 230 is strongly pressed outward with the fingers as shown in FIG. Then, the pressing plate 260 is deformed so that the gap 232 becomes smaller against the elasticity of the pressing plate 260, and the bite is released. This deformation is limited to the range of the gap 132. At this time, the tension plate 210 is also slightly deformed. By the way, the presser plate 260 is reversed at this stage.
Although it does not mean that the pressing plate 260 is released when it bites, there is no concern because the pressing plate 260 is pressed by the slidable curved surface 262. In the above state, the mounting bracket 200 can be pushed up, and further, the operation can be performed in the opposite direction to that of FIG. 4 to detach the instrument body 100 from the ceiling surface.

[0007]

As described above, according to the present invention, since the bite is strengthened by the elasticity of the pressing plate and the bite is released by the deformation against this elasticity, the releasing operation is easy.
Further, it is possible to prevent the mounting bracket from being excessively deformed or damaged due to the release.
