Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an embedded lighting fixture such as a downlight that is embedded in a ceiling surface or the like.

[0002]

[Prior art]

 A conventional example is shown in FIG. That is, in this embedded type lighting fixture, a frame 51 is provided at the lower end of the fixture body 50, and the frame 51 is fitted into the embedded hole 53 of the ceiling 52 and fixed to the ceiling 52 by the mounting spring 54 and the frame 51. Reference numeral 55 is a reflector, 56 is a lamp socket, and 57 is a terminal block.

In another conventional example, as shown in FIG. 7, a mounting member 58 is used instead of the mounting spring 54. Reference numeral 59 is an electric wire connecting portion. These embedded luminaires have the advantage that even if the embedded hole 53 has some distortion or distortion, it can be covered by the frame 51.

[0004]

[Problems to be solved by the device]

 In the recent architectural design, a space design of a lighted room is being performed. At that time, since the downlight originally requires the production of light, the existence of the frame 51 hinders the design design. On the other hand, it is quite possible to improve the accuracy of making embedded holes.

Therefore, an object of the present invention is to provide an embedded luminaire in which the frame can be omitted and the design can be improved.

[0006]

[Means for Solving the Problems]

 The embedded luminaire according to the present invention comprises a fitting having a cylindrical shape having both ends opened and having an engagement receiving portion inside and being attached to an embedding hole, and the engagement receiving portion fitted to the attachment. And an instrument main body having an engaging member for engaging with the outer peripheral surface.

[0007]

[Action]

 According to the configuration of the present invention, the fixture body is attached to the fixture by attaching the fixture to the embedding hole and locking the engagement tool of the fixture body to the fixture. In this case, since the fitting of the main body of the fixture is attached to the fixture of the embedded hole, the conventional frame can be eliminated, and the lighting fixture and the mounting surface such as the ceiling are integrated to improve the design.

[0008]

【Example】

 A first embodiment of the present invention will be described with reference to FIGS. That is, this embedded lighting fixture includes the fixture 1 and the fixture body 2. The fitting 1 is a tubular shape having an opening at both ends and having a lock receiving portion 3 inside, and is attached to the embedding hole 4. The mounting tool 1 of the embodiment has an outer diameter substantially equal to the inner diameter of the embedding hole 4, and the locking receiving portion 3 is a female screw formed on the inner circumference of the mounting tool 1 as an embodiment. It is attached to the ceiling 12. Reference numeral 8 is a hole for the mounting screw 6.

The instrument main body 2 has an engagement tool 5 on the outer peripheral surface, which is engaged with the attachment tool 1 and is engaged with the engagement receiving portion 3. The instrument main body 2 of the embodiment has a cylindrical shape and is internally provided with electric parts (not shown) such as a lamp socket. Reference numeral 7 is an electric wire connecting portion. The engagement tool 5 is ring-shaped and has an external thread formed on the outer circumference, and is rotatably mounted between the collar 9 at the lower end of the instrument body 2 and the retaining projection 10.

According to this embodiment, the attachment 1 is attached to the embedding hole 4 with the attachment screw 6, the instrument main body 2 is fitted into the attachment 1 from below, and the engagement tool 5 is screwed into the attachment 1. It is installed by. In this case, only the engagement tool 5 needs to be rotated with respect to the instrument body 2. In this way, since the fitting 5 of the fixture body 2 is attached to the fixture 1 of the embedding hole 4, a conventional frame can be eliminated, and the lighting fixture and the mounting surface such as the ceiling are integrated to improve the design. It

A second embodiment of the present invention is shown in FIGS. 4 and 5. That is, in this embedded lighting fixture, the inner collar having the upwardly bent portion 14 formed at the inner end is used as the locking receiving portion 3 of the fixture 1, and the peripheral side portion of the lower end of the fixture body 2 is extended downward. And a ring-shaped engaging tool 5. Reference numeral 15 is a notch for tightening the mounting screw 6 formed corresponding to the hole 8 for the mounting screw 6. Reference numeral 16 is a hook-shaped notch, and a retaining protrusion (not shown) provided on the inner circumference of the engagement tool 5 is engaged with the hook-shaped notch 16 to prevent the instrument body 2 from coming off the engagement tool 5. ing.

According to this embodiment, the device body 2 is raised above the ceiling in advance, the fixture 1 is attached to the embedding hole 4 with the attaching screw 6, and the engaging device 5 of the device body 2 is attached to the fixture 1. The retainer 3 is mounted on the lock receiving portion 3, and the retainer projection is inserted into the key-shaped notch 16 and is rotated and engaged so that the retainer is fixed. Therefore, the mounting is easier than in the first embodiment.

[0013]

[Effect of device]

 According to the embedded luminaire of the present invention, the fixture main body is attached to the fixture by attaching the fixture to the embedded hole and locking the fixture of the fixture main body to the fixture. This is unnecessary, and there is an effect that the lighting fixture and the mounting surface such as the ceiling are integrated and the design is improved.
