[Detailed description of the device]

[0001]

[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 has a frame 52 in which a main body 50 is formed with a collar 51 that engages with a lower edge of an embedded hole (not shown) in the ceiling, and a gate-shaped frame with both ends. The main body portion 53 attached to the frame 52, the socket base 54 attached so as to project to the rear side at the upper end portion of the main body portion 53, and the front end portion attached to the inside of the front end portion of the socket base 54 with the front end portion as the center. It consists of the facing lamp socket 55. Further, elastic mounting members 57 are provided which extend outwardly and upwardly from both ends of the main body 53 and elastically lock to the upper edge of the embedding hole. Reference numeral 56 is a lamp mounted in the lamp socket 55. In addition, a folded back portion is formed at the tip of the mounting member 57 to prevent falling.

In this embedded lighting fixture, the fixture main body 50 has a flange 52 that engages with the lower edge portion of the embedded hole in the ceiling at the lower end portion, and is fitted into the embedded hole. Since the lamp socket 55, which is a protruding portion that protrudes toward the rear surface of the ceiling, is provided on the side surface and the center of gravity is biased toward the lamp socket 55 side, the following is performed when embedding in the ceiling. That is, when the mounting body 57 and the mounting member 57 are inserted into the embedding hole while the mounting member 57 is moved closer to the equipment body 50 side and the lamp socket 55 side, which is the protruding portion, is inserted into the embedding hole first, The mounting member 57 elastically locks to the upper edge of the embedding hole by the elastic force of the member 57 that opens outward from the instrument body 50, and clamps the ceiling together with the collar 51 that engages with the lower edge of the embedding hole. Hold the recessed luminaire on the ceiling.

[Problems to be solved by the device]

 However, this embedded lighting fixture has a drawback in that workability is poor because it is necessary to narrow the mounting member 57 while inserting the lamp socket 55 side, which is the protruding portion, into the embedded hole first. 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 tool, which increases the operating force during construction and increases operator fatigue.

In addition, in the case where the center of gravity is eccentric as in the conventional example, the mounting member cannot completely hold it, and a gap is generated between the frame and the ceiling surface, which often causes light leakage. The same was true for embedded lighting fixtures for fluorescent lamps, in which heavy objects such as ballasts were laterally attached to the fixture body and protruded from the side surface and the center of gravity was eccentric. Therefore, an object of the present invention is to provide an embedded luminaire which has a projecting portion on the side where the center of gravity of the luminaire is biased, which facilitates the burying work and prevents light leakage. is there.

[0006]

[Means for Solving the Problems]

 The embedded luminaire according to the present invention has a collar at the lower end that engages with the lower edge of the ceiling embedded hole, and is fitted into the embedded hole more than the ceiling hole of the ceiling. A device main body having a protrusion on the side surface and having a center of gravity biased toward the protrusion, and a device body extending outward and upward from both sides of the protrusion of the device main body in the protruding direction. And a mounting member having elasticity for elastically locking the upper edge of the insertion hole.

[0007]

[Action]

 According to the configuration of the present invention, the device body is tilted and inserted into the embedding hole so that the projecting portion of the device body and the mounting member on the projecting portion side are inserted into the embedding hole first, and then the mounting member is embedded in the embedding hole. Rotate the main body of the fixture while pressing it against the upper edge of the, and insert the mounting member on the opposite side into the embedded hole in the ceiling. It is elastically locked to the part. In this case, the instrument main body can be embedded in the embedding hole without closing the mounting member, and it is not necessary to close the mounting member before embedding as in the conventional case. Since the mounting member is provided on the side, the mounting becomes firm, and it is possible to prevent the occurrence of a gap between the collar and the ceiling surface and prevent light leakage.

【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 main 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 is fitted into the embedding hole 3 so that it is located closer to the ceiling 1 than the embedding hole 3. The center of gravity is biased to the side of the protruding portion 6 by having the protruding portion 6 protruding on the back surface side on the side surface. The embedded hole 3 has a round shape. The device main body 2 has a frame 7 having a brim 4, a gate-shaped main body 8 having the frames 7 attached to both ends, and a rivet 9 attached to the upper end of the main body 8 to project in the direction of the back of the gate. And a lamp socket 11 which is attached to the inner surface of the tip of the socket base 10 and whose tip faces the center of the body 8. In this case, the tip portions of the lamp socket 11 and the socket base 10 become the protrusions 6 projecting from the projection of the embedding hole 3, and the protrusions 6 cause the center of gravity of the fixture body 2 to be biased toward the protrusions 6 side, which results in uneven load. Has become. A lamp 12 is attached to the lamp socket 11.

The mounting member 5 has elasticity that extends outward and upward from both sides in the projecting direction of the projecting portion 6 of the instrument body 2 and elastically engages with the upper edge of the embedding hole 3. The mounting member 5 of the embodiment is formed of a rectangular plate spring, and one end of the mounting member 5 is mounted on the frame 7 by a mounting tool 16 such as a rivet. Reference numeral 15 is a curling portion for preventing falling. The reflector 13 is attached to the main body portion 8. In the embodiment, the reflector plate 13 has a trumpet shape and is fitted to the frame 1, and the upper end portion of the reflector plate 13 is attached to a reflector plate attaching portion (not shown) provided on the main body portion 8. I am installing. The reflector 13 has a lamp socket insertion hole (not shown) on the side surface, and the lamp 12 is mounted in the lamp socket 11 from inside the reflector 13 through the lamp socket insertion hole.

According to this embodiment, the device body 2 is tilted and inserted into the embedding hole 3 so that the projecting portion 6 of the device body 2 and the mounting member 5 on the projecting portion 6 side are inserted into the embedding hole 3 first. Then, while the mounting member 5 is pressed against the upper edge of the embedding hole 3, the fixture body 2 is rotated and the mounting member 5 on the opposite side is inserted into the embedding hole 3 of the ceiling 1. The mounting member 5 is elastically locked to the upper edge of the embedding hole 3 by the elastic force of the mounting member 5 that opens. In this case, the instrument main body 2 can be embedded in the embedding hole 3 without closing the attachment member 5, and since the work of closing the attachment member before embedding as in the conventional case is not required, the embedding work can be facilitated, In addition, since the mounting member 5 is provided on the side of the center of gravity that is biased, the mounting becomes firm, and it is possible to prevent the occurrence of a gap between the collar 4 and the ceiling surface and prevent light leakage.

In the above-mentioned embodiment, the lamp socket of the incandescent lamp is laterally attached to the main body of the fixture to form the protruding portion. However, in the embedded lighting fixture of the present invention, the ballast of the fluorescent lamp is laterally attached to the protruding portion. But it's okay.

[Effect of the device]

 According to the embedded luminaire of the present invention, the lower end has a collar that engages with the lower edge of the embedded hole in the ceiling, and the recess is fitted into the embedded hole more than the embedded hole. An instrument main body having a protruding portion on the back side of the ceiling and having a center of gravity biased toward the protruding portion side, and extending outward and upward from both sides of the protruding portion of the instrument main body in the protruding direction. Since the mounting edge having elasticity for elastically locking the upper edge of the embedding hole is provided, the tool body is tilted so that the projecting portion of the tool body and the mounting member on the projecting side are inserted into the embedding hole first. The mounting body on the upper edge of the mounting hole, and then rotate the fixture body to insert the mounting member on the opposite side into the mounting hole on the ceiling. The elastic force of the mounting member that opens to the upper position causes the mounting member to elastically lock to the upper edge of the embedding hole. The body of the device can be embedded in the embedding hole without closing the member, and it is not necessary to close the mounting member before embedding as in the past, so the embedding work is easy and the mounting member is located on the side of the eccentric center of gravity. Since it has the structure, the mounting is strong, and it is possible to prevent light leakage due to the formation of the gap between the brim and the ceiling surface.
