[Industrial application]

 This invention relates to an embedded luminaire.

[0002]

[Prior Art]

 A conventional example is shown in FIG. That is, this embedded type lighting fixture includes a main body 50 of a fixture which has a flange 51 at a lower end portion which engages with a lower edge portion of a ceiling embedded hole (not shown) and which is fitted into the embedded hole. An elastic mounting member 52 is provided which extends outwardly and upwardly from both sides of the instrument body 50 and elastically engages with the upper edge of the embedding hole. 54 is a curling part that is hooked on the peripheral edge of the embedding hole so that the device body 50 does not drop due to vibrations, etc., 55 is a reflecting plate, and 56 is a socket base, and a lamp socket (not shown) is attached to the socket base 56. .

In this embedded lighting fixture, when the main body 50 of the fixture and the mounting member 52 are inserted into the embedded hole while the mounting member 52 is moved toward the main body 50 of the fixture, the mounting member 52 is exposed outward from the main body 50 of the fixture. The mounting member 52 is elastically locked to the upper edge of the embedding hole by the elastic force of opening, and the ceiling is clamped together with the flange 51 that engages with the lower edge of the embedding hole to hold the embedding type lighting fixture on the ceiling. To do.

[Problems to be solved by the device]

 However, this embedded lighting fixture has a drawback in that workability is difficult because the mounting member 52 needs to be narrowed toward the fixture body 50 side when the fixture body 50 is inserted into the embedded hole. In particular, since the holding power of the embedded lighting fixture can be improved if the expansion force for the embedded hole is increased, the initial angle of the mounting member with respect to the mounting portion is large for a device with a relatively large fixture weight. A large force is also required to close the mounting member toward the center of the equipment, and the operating force during construction becomes large, and a great deal of fatigue is required when mounting a large number of equipment.

Therefore, an object of the present invention is to provide an embedded lighting fixture in which a mounting member can be easily inserted into an embedded hole.

[0006]

[Means for Solving the Problems]

 The embedded luminaire of the present invention has a main body of a fixture which fits into the embedded hole having a collar at the lower end which engages with the lower edge of the embedded hole of the ceiling, and both side portions of the main body of the fixture. A mounting member having an elasticity that extends outwardly upward and elastically locks to the upper edge of the embedding hole, and the mounting member has a bent portion at an intermediate portion and is located at a tip side of the bent portion. Is close to the equipment body.

[0007]

[Action]

 According to the configuration of the present invention, when the main body of the device is inserted into the embedding hole while the tip of the mounting member is brought close to the device body, the mounting member is embedded by the elastic force of the mounting member that opens outward from the device body. Elastically locks to the upper edge of the hole. In this case, since the mounting member has a bent portion in the middle and the tip side is closer to the instrument body, the mounting member can be embedded with a slight operation compared to a mounting member without a bent portion as in the conventional example. Since it can be inserted into the mounting hole, the mounting member can be easily inserted into the mounting hole, and the labor for mounting a large number of devices is significantly reduced.

【Example】

 An embodiment of this invention will be described with reference to FIGS. That is, this embedded lighting fixture has the fixture body 2 and the mounting member 5. The instrument body 2 has a collar 4 that engages with the lower edge of the embedding hole 3 of the ceiling 1 at the lower end and fits into the embedding hole 3. The instrument main body 2 has a frame 7 having a collar 4, a gate-shaped main body 8 having both ends attached to the frame 7 by rivets and the like, and a gate-shaped main body 8 attached to the upper end of the main body 8 with rivets 9 and the like. A socket base 10 that projects toward the rear, a lamp socket 11 that is attached to the inner surface of the tip of the socket base 10 and faces the center of the main body 8, and a terminal 12 that is attached to the outer surface of the tip of the socket base 10. Consists of. The main body portion 8 is formed of a strip-shaped leaf spring, and is provided with an inclined portion 17 on the upper end side of the side portion for allowing the tip portion 16 of the mounting member 5 to escape. A lamp 14 is attached to the lamp socket 11.

The attachment member 5 has elasticity that extends outward and upward from both sides of the instrument body 2 and elastically engages with the upper edge of the embedding hole 3. Further, the bent portion 6 is provided in the middle portion, and the tip 16 side of the bent portion 6 is closer to the instrument body 2. The mounting member 5 of the embodiment is integrally formed so as to extend from both ends of the main body 8. Further, the bent portion 6 is formed so as to project outward so that it can be easily retained and locked in the upper edge portion of the embedding hole 3, and the tip 16 in a free state is substantially upward as shown in FIG. It has a shape to face.

The reflection plate 13 is attached to the main body portion 8. In the embodiment, the reflection plate 13 has a trumpet shape and is fitted into the frame 7, and the opening edge of the upper end portion of the reflection plate 13 is cut and raised in the main body portion 8 to be integrally formed. It is locked to the pair of doglegged reflector mounting portions 18. The reflector plate 13 has a lamp socket insertion hole 19 on its side surface, and the lamp 14 is attached to the lamp socket 11 from inside the reflector plate 13 through the lamp socket insertion hole 19.

According to this embodiment, when the instrument main body 2 is inserted into the embedding hole 3 while the tip of the attachment member 5 is brought close to the instrument body 2, the elasticity of the attachment member 5 that opens outward from the instrument body 2 is obtained. The mounting member 5 is elastically locked to the upper edge of the embedding hole 3 by force. In this case, since the mounting member 5 has the bent portion 6 in the middle portion and the tip side is close to the instrument body 2, it requires a little operation as compared with the mounting member having no bent portion as in the conventional example. Since the mounting member 5 can be passed through the embedding hole 3, the mounting member 5 can be easily inserted into the embedding hole 3, and the labor for mounting a large number of instruments is significantly reduced.

Further, in this embodiment, even if the instrument body 2 comes down from the embedding hole 3 due to vibration or the like, the bent portion 6 of the mounting member 5 is locked to the upper edge portion of the embedding hole 3 to prevent falling. To be done. Further, if the bent portion 6 is set to a position where it is locked to the upper edge portion of the embedding hole 3 of the ceiling 1 by dimension setting, it is possible to prevent falling and prevent a gap between the collar 4 and the ceiling surface from occurring. Further, by providing the inclined portion 17 on the main body portion 8, the tip end 16 of the mounting member 5 can be positioned on the inclined portion 17 when approaching the body 2 side of the instrument, so that it can be easily inserted into the embedding hole 3 and the packaging during transportation is small. it can.

[Effect of the device]

 According to the embedded luminaire of the present invention, a fixture main body which has a flange at the lower end to engage with the lower edge of the embedded hole of the ceiling and fits into the embedded hole, and the fixture main body And a mounting member having elasticity that extends outward and upward from both sides and elastically locks to the upper edge of the embedding hole, and the mounting member is retained at the upper edge of the embedding hole. Since the bendable part that can be locked is provided in the middle part and the tip side of the bent part is closer to the instrument body, the mounting member can be operated with a slight operation compared to a mounting member having no bent part as in the conventional example. Since the mounting member can be inserted into the embedding hole, the mounting member can be easily inserted into the embedding hole, and the labor for mounting a large number of devices can be significantly reduced.
