DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power plug mounting structure for spot lighting which can be fixed from any direction of a duct rail.

[0002]

2. Description of the Related Art Spot lighting for effectively producing products at food counters and various exhibition halls is based on lamps of lighting fixtures fixed to a duct rail wired to a ceiling, but the lighting fixture itself is ducted through a power plug. Attached to the rail. As shown in FIG. 3, the duct rail 50 has an inwardly bent surface 51 at the lower left and right ends in the longitudinal direction like the curtain rail, and a wiring mounting portion 53 of the conductive plate 52 in the middle of the left and right.
At one corner (right side in the figure) of the bent surface 51, there is a ridge 54, and a right-angled notch 61 formed on one side of the main body 60 of the power plug engages with the ridge 54. It has a configuration to do. The main body 60 is accurately attached to the duct rail 50 when the notch 61 engages as if the ridge 54 functions as a stopper.

[0003]

According to the above prior art, the opposite side of the notch 61 is flat and cannot be matched with the ridge 54. Therefore, the direction of the power plug main body 60 is limited to only one direction. Therefore, depending on the position of the duct rail 50, there is an inconvenience that the main body 60 is rotatably mounted on the other side, and the work efficiency is poor.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and it is possible to mount a power plug regardless of the direction of a duct rail so as to improve work efficiency without increasing costs. It is intended to be realized.

[0005]

That is, the present invention relates to a spot lighting power plug mounting structure for supporting a lighting fixture 20 to which a lamp 21 is mounted along a duct rail 10, in which a duct rail 10 is provided on the left and right sides of a main body 31. A right-angled notch 32 that matches the ridge 12 provided at one corner in the longitudinal direction.
32 ', and the flat upper surface having the right-angled notches 32 and 32' is in close contact with the bent surface 11 of the duct rail 10, and the power plug 30 is fixed from the same direction regardless of the direction of the duct rail 10. What we can do is technical means.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the drawings. FIG. 1 is a side view in which a lighting fixture 20 to which a lamp 21 for spot lighting is mounted is provided along a duct rail 10. Power plug 3 fixed on top
0, is attached to the duct rail 10, and the duct rail 10 is fixed to a ceiling (not shown). As shown in (a) and (b), the power plug 30 can be attached even if the duct rail 10 is left in its original position, so that the lighting fixture 20 can be installed. Nothing changes.

FIG. 2 (a) shows the front shape of the duct rail 10, in which an inwardly bent surface 11 is formed on the left and right ends in the longitudinal direction similarly to the curtain rail, and one side of the bent surface 11 (right side in the figure). ) A ridge 12 is vertically provided at a corner, and a wiring mounting portion 14 of a conductive plate 13 is provided in the middle of the left and right sides. A concave groove 15 is formed between the bent surface 11 and the wiring mounting portion 13. You.
An earth plate 16 is arranged on the inner surface at the center of the top.

A power lamp 30 located on the upper part of the lighting apparatus 20 has an elongated main body 3 having a flat upper surface as shown in FIG.
Right-angled notches 32 and 32 'are formed at the upper ends on both sides of 1 and a knob 34 protrudes outward from a slot 33 provided at one corner. And the wing body 3 provided on the knob 34 and the upper part of the main body 31
5 cooperate with each other, and the left and right terminals 37 provided in a case 36 attached to the wing 35 protrude outward simultaneously with the wing 35. That is, the wing 35 and the terminal 37 are operated in accordance with the movement of the knob 34 protruding to one side.
In the state in which the wing 4 protrudes to the side of the main body 31, the wing body 35 is shaped along the length of the main body 31, and the terminal 37 is connected to the case 3.
6, and the knob 34 is rotated to rotate the main body 3
When the wing body 35 is located at the center of the wing 1, the wing body 35 projects left and right, and the left and right terminals 37 project from the case 36. At this time, a metal piece 38 protruding above the center of the wing body 35
Also rotates.

FIG. 2C shows a state in which the power supply lamp 30 is attached to the duct rail 10. When the knob 34 is turned, the wing 35 is engaged with the concave groove 15 of the duct rail 10. The lamp 30 is fixed to the duct rail 10. The duct rail 10 has the ridges 12, but the main body 31 of the power lamp 30 has right-angled notches 32 and 32 ′, one of the notches 32 matches the ridge 12, and the right and left bent surfaces 11. The power lamp 30 is securely engaged with the duct rail 10 because the flat upper surface is in close contact. The terminals 37 projecting left and right simultaneously with the wing body 35 are connected to the conductive plate 13 of the wiring mounting portion 14.
The metal piece 38 that is in close contact with the wing body 35 and protrudes upward from the center of the wing body 35 also contacts the ground plate 16. Since the lighting fixture 20 is attached to the power plug 30, when the power lamp 30 is fixed to the duct rail 10, the lighting fixture 20 and the lamp 21 are also fixed, and the lamp 21 can be turned on at any time.

FIG. 2 (d) shows a state in which the power supply lamp 30 is mounted on the duct rail 10 in the opposite direction to the above figure (b), so that the knob 34 is located on the other side. Does not appear. Since the main body 31 is formed with right-angled notches 32 and 32 ′ on both sides,
Of the duct rail 10 even if the direction of the
Does not cause any problem in mounting the power plug 30, so that the lighting fixture 20 to which the lamp 21 is mounted can be fixed at a desired position.

Since the wing body 35 and the terminal 37 do not protrude left and right unless the knob 34 is turned, the power lamp 30 can be attached from below the left and right bent surfaces 11 of the duct rail 10 regardless of the front and rear directions. When the knob 34 is rotated in the opposite direction, the wing body 35 and the terminal 37 disengage from the concave groove 15 and the wiring mounting portion 14, so that the power plug 30 can be removed from the duct rail 10.

[0012]

The power plug can be fixed from either direction of the duct rail by the right-angled notches formed on both sides of the power plug main body conforming to the ridges of the duct rail. The inconvenience that the installation work of the power plug is troublesome depending on the position is eliminated. Since the right-angled notch of the power plug is formed on both sides instead of the conventional one, there is also an advantage that the material can be provided at a low cost because the material cost is low and the manufacturing is simple.
