Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a mounting fixture for a ceiling-embedded luminaire.

[0002]

[Prior art]

 As shown in FIG. 4, this type of ceiling-embedded luminaire has a mounting vertical slit 2 on the side wall of the main body 1 of the fixture, and a mounting hole 3 continuously formed at the upper end of the vertical slit 2 for mounting. The mounting bracket 4 is inserted through the hole 3 so that it can move up and down in the vertical slit 2, and the lower end of the mounting bracket 4 is mounted on the ceiling 5 surface as shown in FIG. A structure is adopted that abuts on and locks. The mounting bracket 4 is disclosed in, for example, Japanese Patent Publication No. 1-43964, and as shown in FIG. It is composed of a base end portion 7 arranged inside the side wall, and these are formed by a press die from a single plate body.

More specifically, the insertion portion 6 side is inserted into the vertical slit 2 from the inside, and the ceiling engaging portion 8 that abuts the ceiling 5 surface on the inserted lower end side and the upper end side of the fixture body 1 The anti-rotation piece 9 that comes into contact with the outer surfaces of both side walls of the vertical slit 2 and restricts the movement of the vertical slit 2, and the anti-rotation piece 9 provided on the anti-rotation piece 9 and digging into the outer surface of the side wall of the instrument body 1 moves upwards of the mounting bracket 4. And a locking spring 10 for preventing the movement of the. Further, the base end portion 7 side is formed to be wider than the width of the vertical slit 2 and is extended from the guide piece 11 that is in sliding contact with the inner surface of the side wall of the instrument body 1, and the insertion portion 6 is locked. An operation piece 12 for releasing the lock of the spring 10 and lifting the instrument body 1 is formed.

The mounting bracket 4 having such a structure is composed of one component, can be manufactured at low cost, and the mounting of the lighting fixture can be securely fixed only by pushing down the mounting bracket 4 along the vertical slit 2. It has excellent features such as easy work.

[0005]

[Problems to be solved by the device]

 By the way, in the above-mentioned conventional ceiling-embedded luminaire, the ceiling locking portion 8 at the lower end of the mounting bracket 4 is brought into contact with the surface of the ceiling 5 to be locked, but the mounting bracket 4 is in contact with the construction material of the ceiling 5. The touching part has a structure in which the side of the metal plate of the metal fitting 4 directly abuts, and when the weight of the lighting fixture or vibration is applied to the lighting fixture, the sharp contact portion of the mounting fixture 4 bites into the construction material of the ceiling 5. There was an occasion. Therefore, as shown in FIG. 5, there is a problem that a gap m is formed between the surface of the ceiling 5 and the decorative frame 13 attached to the lower surface of the instrument body 1 to cause light leakage.

Therefore, the present invention has been made in view of the above-mentioned problems, and a lighting device can be stably attached to a ceiling construction material without causing light leakage between the ceiling surface and the decorative frame. It is intended to provide a fixture for a device.

[0007]

[Means for Solving the Problems]

 Therefore, in the present invention, the U-shaped bent curved surface of the mounting bracket is used as the ceiling locking portion, and the non-slip projections are arranged on the periphery of the U-shaped bent curved surface.

[0008]

[Action]

 Since the ceiling locking part of the mounting bracket is formed with a U-shaped bent curved surface, it will come into contact with the ceiling construction material and prevent it from biting. In addition, the protrusions on the periphery of the U-shaped folded curved surface prevent the appliance body from slipping.

[0009]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a mounting bracket 15 of a ceiling-embedded luminaire according to the present invention. Similar to the mounting bracket 4 of FIG. 4, the mounting bracket 15 is also a one-piece component obtained by forming a plate body by press working or the like, and has an insertion portion 16 bent in a substantially U-shape. It is composed of a base end portion 17 formed to be wider than the vertical slit 2. On the insertion portion 16 side, a U-shaped bent curved surface is arranged on the lower end side, and a ceiling locking portion 18 that abuts the ceiling 5 surface, and on the upper end side, outer surfaces of both side walls of the vertical slit 2 of the instrument body 1. And a locking spring 19 provided on the locking body 19 to prevent the movement of the mounting bracket 15 upward by engaging with the outer surface of the side wall of the instrument body 1. And 20 are formed.

Further, the base end portion 17 side is formed to be wider than the width of the vertical slit 2, and a guide piece 21 that is in sliding contact with the inner surface of the side wall of the instrument body 1, and a rear side from the guide piece 21 and a further upper end thereof are horizontal. An operation piece 22 is formed which is bent and formed to release the locking of the locking spring 20 and lift the instrument body 1. Further, anti-slip projections 23 and 24 are provided on the rear end edge and the front end edge of the ceiling engaging portion 18 on the insertion portion 16 side.

FIG. 2 and FIG. 3 are cross-sectional views of essential parts showing a state in which the lighting fixture is mounted on the ceiling 5 surface using the mounting bracket 15 described above. The part 18 has a flat bent surface and is in surface contact with the construction material of the ceiling 5. When the lighting fixture is attached to the ceiling 5 surface by pulling down the fitting 15 downward, the anti-slip projections 23 and 24 on the peripheral edge bite slightly into the construction material of the ceiling 5, but the ceiling locking portion 18 makes surface contact. Therefore, it does not bite further, and prevents the instrument body 1 from slipping on the horizontal plane.

[0012]

[Effect of device]

 As described in detail above, according to the present invention, the U-shaped bent curved surface of the mounting bracket composed of a single component is used as the ceiling locking portion, and the non-slip projections are arranged on the periphery of the U-shaped bent curved surface. The metal fittings make surface contact with the construction material on the ceiling and prevent it from biting. In addition, the projection on the peripheral edge of the U-shaped bent curved surface prevents the horizontal plane of the instrument body from slipping. Therefore, the device body can be stably attached to the construction material of the ceiling without causing light leakage between the ceiling surface and the decorative frame.
