(Prior art) For lighting fixtures, as described in, for example, Japanese Utility Model Publication No. 59-41530 or Japanese Utility Model Publication No. 59-41531, there are ceiling-mounted lighting fixtures in which the main body of the fixture is embedded in the ceiling surface. be.

For example, as shown in FIG.
There is a structure in which a reflector 3 is attached to the lower surface of the lamp, and a straight tube lamp 4 is connected to a lamp socket 5 below the reflector 3.

And such ceiling recessed lighting equipment,
Conventionally, as shown in FIG. 5, a rectangular box frame-shaped appliance body 2 that opens downward is embedded through an opening 7 in a ceiling plate 6, and a side plate 11 and an end plate 12 (as shown in FIG. 4) of this appliance body 2 are installed. The mounting piece 13 bent outward from the lower peripheral edge is joined to the ceiling surface 1 at the edge of the opening 7, and the reflector 3 is attached to the reflector mounting bracket 14 installed inside the appliance body 2 using a plurality of screws. It is tightened and fixed with 15. This reflector 3 is constructed by bending side reflectors 17 downward from both side edges of a top reflector 16 that is tightened and fixed by screws 15 into an expanded shape.
An end reflector 18 (shown in FIG. 4) is attached to the end face, and the mounting piece 13 of the instrument body 2 is attached to the lower edge of the side reflector 17 and the end reflector 18.
A frame portion 21 is provided which has a horizontal piece 19 covering the lower surface and a rising piece 20 covering the outer surface.

When the reflector 3 is attached to the instrument body 2, the rising piece 20 of the frame 21 of the reflector 3
is fitted to the outside of the attachment piece 13 of the appliance body 2, and the upper end of the rising piece 20 is joined to the ceiling surface 1, and the attachment piece 13 of the appliance body 2 is covered with the frame part 21.

The object of the present invention is to provide a lighting device that can be kept clean and a reflector that can be easily attached to the device body.

[Structure of the idea]

(Means for Solving the Problems) The present invention consists of a fixture body formed by joining a mounting piece to the ceiling surface, which is embedded in the ceiling surface and bent outward from the lower end edge that opens downward; In the lighting equipment, the lighting equipment is equipped with a reflector that is attached to the lower surface of the main body, has a rising piece on the edge that is joined to the ceiling surface, and is provided with a frame that covers the mounting piece of the equipment main body, the mounting piece of the equipment main body is A mounting spring is provided on the lower side that projects downwardly and inclined outward, and a stopper is provided to restrict the upward displacement of this mounting spring. An engaging piece is provided that projects downwardly and inclines, elastically displaces the mounting spring downward, and engages with the upper surface of the mounting spring.

(Function) In the present invention, by pushing the reflector up against the instrument body, the retaining piece of the reflector can overcome the mounting spring whose upward displacement is regulated by the stopper.
This engaging piece elastically displaces the mounting spring downward and engages with the upper surface of the mounting spring, and the frame portion of the reflector is urged upward by the elasticity of the mounting spring via the engaging piece. , the upper end of the rising piece of the frame is joined to the ceiling surface.

(Embodiment) Hereinafter, the configuration of an embodiment of the present invention will be described with reference to FIGS. 1 to 3.

Note that the same reference numerals are used for the same structural parts as the conventional structure, and the explanation thereof will be omitted.

As shown in FIG. 4, a ceiling-embedded lighting fixture has a reflector 3 attached to the lower surface of the fixture main body 2 that is embedded in the ceiling surface 1, and a straight tube-shaped lamp attached to the underside of the reflector 3. 4 is connected to lamp socket 5 and installed.

As shown in FIGS. 1 to 3, the appliance main body 2, which opens downward, is embedded through the opening 7 of the ceiling plate 6, and is bent outward from the lower edges of the side plates 11 and end plates 12. A mounting piece 13 is joined to the ceiling surface 1.

A mounting spring 31 is fixed to the lower end of the side plate 11 of the device main body 2, and the mounting spring 31 is made of an elastic plate material, and has rivets 3 on the inside of the side plate 11.
A fixed piece 33 fixed by 2, this fixed piece 3
3, a joining piece 34 that is bent at a substantially right angle from the lower end of the mounting piece 13 and joined to the lower surface of the mounting piece 13; a support piece 35 projecting downward and inclined outward from the tip of the joining piece 34; and a tip of the support piece 35. It consists of a guide piece 36 bent in an arc shape below the support piece 35. The attachment spring 31 is attached to the instrument body 2 at several locations in the longitudinal direction of the side plate 11 of the instrument body 2 (in this case, at the frame 2 of the reflector 3, which will be described later).

At this time, the retaining piece 41 of the reflector 3 is attached to the mounting spring 3.
However, since the upper surface of the support piece 35 of this attachment spring 31 comes into contact with the stopper 37 and its upward displacement is restricted, the attachment piece 41
will move upward while displacing outward. This outward displacement is caused by the side reflector 17 and the frame 2.
1 and the entire elastic deformation of the engaging piece 41.

Then, when the tip of the engagement piece 41 crosses over the outermost arc of the guide piece 36 of the mounting spring 31,
As the locking piece 41 moves upward, the tip of the locking piece 41 shifts its contact position to the upper area of the guide piece 36 of the mounting spring 31 due to the elastic force that tends to return inward. Furthermore, when the upper end of the rising piece 20 comes into contact with the ceiling surface 1 and its upward movement is restricted, the first
As shown in the figure, the inward elastic force causes the locking piece 4 to

Therefore, the reflector 3 can be easily attached to the instrument main body 2 by simply pushing up the reflector 3. For example, even if the overall length of the reflector 3 is long, it can be attached by one person. There is no need for operations such as tightening screws, and the workability is good. Moreover, this reflector 3
When the frame 21 is attached, the elastic force of the mounting spring 31 urges the frame 21 upward via the locking piece 41, so that the upper end of the rising piece 20 of the frame 21 is always on the ceiling surface 1. The appearance of the appliance can be maintained neatly without causing a gap between the frame part 21 and the ceiling surface 1 due to the downward deformation of the frame part 21 when they come into contact with each other.

In addition, when removing the reflector 3 from the instrument body 2, the frame portion 21 is expanded outward to remove the reflector 3.
By pulling down, the tip of the engagement piece 41 comes off from the attachment spring 31, and the reflector 3 can be easily removed.

Further, by forming the engaging piece 41 by bending the frame portion 21 of the reflector 3, the rigidity of the reflector 3 can be improved.

In addition, in the above embodiment, the support piece 3 of the mounting spring 31
An arc-shaped guide piece 36 is provided at the tip of the retaining piece 5, and this guiding piece 36 guides the tip of the engaging piece 41 of the reflector 3 to the upper surface of the supporting piece 35 of the mounting spring 31.
An arc-shaped guide piece may be provided at the tip of the spring 1, or may be provided on both the mounting spring 31 and the engaging piece 41. Note that by providing these guide pieces, the locking piece 41 can be easily connected to the upper surface of the support piece 35 of the mounting spring 31; It is possible to attach the spring 31 to the upper surface of the support piece 35.

[Effect of idea]

According to the present invention, a mounting spring is provided on the main body of the device, and a fastening piece that is fastened to the mounting spring is provided on the frame of the reflector, and the elasticity of the mounting spring causes the frame to move upward through the fastening piece. In order to energize the frame, the upper end of the rising piece of this frame is always connected to the ceiling surface, so that the frame does not fall downward and deform and create a gap between it and the ceiling surface, improving the appearance of the appliance. It can be kept clean, and it can be easily installed by simply pushing the reflector up against the main body of the device.
For example, even if the overall length of the reflector is long, it can be installed by one person, and there is no need to perform operations such as tightening screws, resulting in good workability.
