[0003]
[Problems to be solved by the invention]
Conventionally, there is a flange portion 55 in contact with the lower surface of the duct on only one side, and the upper surface of the flange portion 55 in contact with the lower surface of the duct in the mounted state is flush with the duct mounting surface 51 of the device main body 52. There is a function to support the main body 52, but there is no function to push it up.
[0004]
As a result, as shown in FIG. 5, in the irradiation direction in which the weights of the instrument main body 52 and the lamp 56 are concentrated on the opposite side of the lever 54 around the plug portion 53, the gap 57 between the wiring duct A and the instrument main body 52 is obtained. There is a problem that occurs. The gap 57 increases as the length of the main body increases.
[0005]
Accordingly, an object of the present invention is to provide a wiring duct device that can eliminate a gap between the device main body and the wiring duct.

In addition, since the insertion guide portion is provided on the lever, it is easy to move the push-up portion of the lever below the wiring duct.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
A first embodiment of the present invention will be described with reference to FIGS. That is, the wiring duct lighting fixture has a fixture body 1, a plug portion 2, and a lever 3.
[0009]
In the appliance main body 1, the duct mounting surface 5 comes into contact with the lower surface of the wiring duct A. A normal wiring duct has a cross-sectional structure of a substantially groove-shaped steel, and a conductor is arranged along the longitudinal direction on the opposite inner side surface, and the opening edge projects in the opposite direction along the longitudinal direction. It is the structure which provided the stop piece. The appliance main body 1 of the embodiment has a protrusion 6 that enters the opening of the wiring duct A on the duct mounting surface 5, and the arm 7 is suspended from one end side in the longitudinal direction of the wiring duct A on the lower surface of the appliance main body 1. In addition, the lamp 8 is attached to the lower end portion of the arm 7 so as to freely swing. Since the protrusion 6 is engaged with the opening of the wiring duct A, a lateral shift from the wiring duct A can be prevented.
[0010]
The plug portion 2 is rotatably provided at one end in the longitudinal direction of the wiring duct A on the duct mounting surface 5 of the instrument body 1 and is electrically and mechanically connected to the wiring duct A by inserting and rotating. The plug portion 2 of the embodiment protrudes above the duct mounting surface 5 at the same position as the arm 7 of the duct mounting surface 5. The contact piece 9 that contacts the conductor of the wiring duct A by rotation is extended on both sides of the upper end portion of the plug portion 2, and the duct mounting surface 5 abuts the lower surface of the wiring duct A below the contact piece 9 of the plug portion 2. In this state, the mounting piece 10 that is locked by rotation is projected on the inner upper surface of the locking piece of the wiring duct A. Then, power is supplied to the lamp 8 from the contact piece 9 of the plug portion 2 through the instrument body 1 and the arm 7.
[0011]
The lever 3 extends outward from the instrument body 1 from the plug part 2 and rotates the plug part 2. The lever 3 has an insertion guide portion 12 that is positioned below the duct mounting surface 5 and faces the lower surface of the wiring duct A in such a posture that the plug portion 2 can be inserted into the wiring duct A, and above the duct mounting surface 5. There is a push-up portion 13 that pushes up the lower surface of the one end side of the instrument body 1 of the wiring duct A in a posture that is positioned and rotated so that the plug portion 2 can be connected to the wiring duct A. In the embodiment, the end portion of the lever 3 is connected to the lower portion of the mounting piece 10 of the plug portion 2, the tip of the lever 3 is bent downward and extends to one end surface of the instrument body 1, and has a substantially L shape. 3 is formed such that a flange portion 14 which is substantially flush with the duct mounting surface 5 extends in the width direction of the wiring duct A, and the insertion guide portion 12 and the push-up portion 13 are continuous as shown in FIG. It is formed in the collar part 14 so as to form.
[0012]
The state shown in FIG. 1 is a state attached to the wiring duct A. When the lighting fixture is removed from this state, the lever 3 is rotated approximately 90 degrees to the back side of FIG. Thereby, since the contact piece 9 and the attachment piece 10 face the longitudinal direction of the wiring duct A, they can be pulled down from the opening of the wiring duct A. On the other hand, when attaching the lighting fixture to the wiring duct A, the lever 3 is set to the state when the fixture main body 1 is pulled down, the fixture main body 1 is lifted to the wiring duct A, and the protruding portion 6 and the plug portion 2 are placed in the opening. In this state, the lever 3 is rotated approximately 90 degrees to the state shown in FIG. At this time, the attachment piece 10 is engaged with the engagement piece at the same time that the contact piece 9 comes into contact with the conductor, and the insertion guide portion 12 continues to slide on the lower surface of the wiring duct A. Touch and stretch against wiring duct A. As a result, the appliance body 1 is pushed up so that the side opposite to the lever 3 approaches the wiring duct A with the attachment piece 10 locked to the locking piece of the wiring duct A as a fulcrum. A gap between the surface 5 is not generated.
[0013]
According to the first embodiment, the insertion guide portion 12 can be easily fitted into the wiring duct A. Further, the push-up portion 13 has a sufficient body push-up force, and in the irradiation direction where the weight of the fixture main body 52 and the lamp 56 is concentrated on the side opposite to the lever 54, or even when the fixture main body 1 is long, it is between the wiring duct A. The conventional gap 57 does not occur.
[0014]
A second embodiment of the present invention will be described with reference to FIG. That is, in this lighting apparatus for wiring duct, compared to the first embodiment, the insertion guide portion 12 is provided on the flange portion 14 via an inclined stepped portion, and the push-up portion 13 is connected to the collar portion 14 with a wiring duct. A different point is formed by the ridges 13 orthogonal to the longitudinal direction of A. Others are the same as in the first embodiment.
[0015]
【The invention's effect】
