Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an optional fixture mounting structure for a lighting fixture in which an optional fixture such as a translucent panel or a louver is attached to an opening of a lighting fixture body.

[Background Art] In conventional lighting fixtures in which an optional fixture such as a translucent panel, glass, or louver is attached to the opening surface of the lighting fixture body, the optional frame is placed on the outside of the frame around the opening of the lighting fixture body. was.
Therefore, when optional fixtures are removed, marks from the frame remain on the ceiling surface, making it unsightly.
In addition, the optional fixtures may hang down, creating a gap between the optional frame and the ceiling surface, and furthermore, when connecting the lighting fixtures, it is difficult to achieve linearity between the lighting fixtures.

As a mounting device for other optional equipment, the first
There is one using a magic spring 51 shown in FIG. This magic spring 51 has the shape of a rod-shaped spring wound in a coil shape at the center, with both sides spread out in a V-shape and the tips bent. Optional equipment B
A square hole 54 is bored in the outer piece of the option frame 3 that supports the outer peripheral edge of the option frame 3, one end is locked in the square hole 54, and the other end is hooked and locked to the wound part of the magic spring 51. A spring plate 53 is attached. A spring receiver 56 having a T-shaped communication hole 55 for elastically contacting both sides of the magic spring 51 is attached to the inner surface of the lighting device main body 1.

Optional device B using this magic spring 51
The installation will be explained according to FIG. 18. This lighting fixture uses a louver as optional fixture B. This louver is placed on the inner peripheral edge of the option frame 3, and in this state, both sides of the magic spring 51 attached as shown in FIG. 17 are compressed inward.
The magic spring 51 is inserted through the narrow portion of the elastic contact hole 55 of the spring receiver 56. And magic spring 5
When the pressing force 1 is released, both sides of the magic spring 51 come into elastic contact with the inner circumferential surfaces of the elongated end of the elastic contact hole 55. At this time, force is applied to the magic spring 51 so that the magic spring 51 comes out upward due to the force that causes both sides of the magic spring 51 to open outward, but the louver
Due to the weight of the option frame 3 and the magic spring 51, the forces are balanced at a position where both sides of the magic spring 51 are expanded to a certain extent. For this reason, magic spring 5
At step 1, an optional fixture B such as a louver can be attached within the opening of the lighting fixture main body 1.

However, when using the magic spring 51,
The height of the lighting fixture main body 1 must be at least higher than the height of the magic spring 51, which inevitably increases the height of the lighting fixture. Furthermore, since it is necessary to provide the spring receiver 56 on the inner surface of the lighting device main body 1, there is also a problem that the shape of the reflector plate 1 is limited. Therefore, when changing a lighting fixture not equipped with the optional fixture B to a lighting fixture equipped with the optional fixture B, it was necessary to replace the reflector plate 1. Furthermore, the elastic force of the magic spring 51 was so strong that the optional appliance B, such as the panel, was sometimes damaged. Furthermore, although the magic spring 51 is used to attach the optional fixture B inside the frame of the lighting fixture body 1, since the optional fixture B is held on the end surface of the lighting fixture body 1, it is difficult to connect the lighting fixtures. In some cases, there were problems where the only option was to butt connect.

[Purpose of the invention] The present invention has been made in view of the above-mentioned points, and its purpose is to enable conversion between a bottom-open type lighting fixture and a lighting fixture with an optional fixture, and to To provide an optional fixture mounting structure for a lighting fixture which is compact and allows an optional frame to be housed in a lighting fixture body.
