Two hanging metal halves 4 and 5 each having concavities and convexities that are continuous at a pitch are arranged so that the peaks 2 of one of the hanging metal half halves 4 and the troughs 3 of the other hanging metal halves 5 are formed. The lowermost ring 8 of the hanging chain 7 whose upper end is fixed to the ceiling is attached to each other in a corresponding manner to form a hanging fitting 6 for hanging the lighting fixture 9.
This relates to a hanging device for a lighting fixture, which is constructed by penetrating the above-mentioned opening 1 and engaging the above-mentioned ring 8 with the valley part 3 of the rain fitting halves 4 and 5, and its purpose is to To provide a hanging device for a lighting fixture that can easily correct the inclination caused by unbalanced weight of the lighting fixture.

The present invention will be described in detail based on an example in which it is used in a lighting fixture as shown in FIG.

This lighting fixture 9 consists of a main body 9a suspended from the lower end of a hanging chain 7 fixed to the ceiling, and a lamp 11 fixed to the tip of an arm 10 fixed at a key point on the side of the main body 9a.
By pulling the drawstring 12, the lamp 11 blinks.

The connecting portion between the hanging chain 7 and the main body 9a is constructed as follows.

That is, as shown in FIGS. 2 to 4, a hanging fitting 6 is formed by bonding two hanging fitting halves 4 and 5, and a hanging fitting 6 is provided at the lower end of the hanging fitting 6 to protrude from the upper end of the main body 9a. Fixing pipe 1
3 and a hanging chain 7 is connected to the opening 1 provided in the hanging fitting 6, thereby hanging the lighting fixture 9 from the ceiling.

To explain each part in more detail, the hanging metal half body 4 made of a flat metal plate is provided with a substantially mouth-shaped opening 1 with a substantially horizontal upper edge in the center, and a pipe 13 projecting rearward in the center of the lower part. A semi-cylindrical protrusion 14 for insertion is provided, and furthermore, burrings 15 and burring insertion holes 16 are provided at symmetrical positions on both left and right sides of the semi-cylindrical protrusion 14, respectively.

Further, the upper edge of the opening 1 is provided with unevenness such that a plurality of pairs of peaks 2 and valleys 3 are continuous at the same pitch.

Then, the two plates of hanging metal parts 4 and 5 are arranged so that the peaks 2 of one of the hanging metal halves 4 and the valleys 3 of the other hanging metal halves 5 correspond to each other, and After pasting the halves 4 and 5 together so that the burrings 15 penetrate through the burring insertion holes 16, the burrings 15 are tightened to form a hanging fixture 6 with a pipe insertion hole 17 formed at the bottom by a half-cylindrical protrusion 14. It consists of

A pipe 13 protruding from the upper end of the main body 9a is inserted into the pipe insertion hole 17 and locked by a shaft 18.

Further, the lowermost ring 8 of the hanging chain 7 whose upper end is fixed to the ceiling is passed through the opening 1, and this lowermost ring 8
are engaged with the valley portions 3 of the hanging metal halves 4 and 5.

FIG. 5 is a cross-sectional view taken along the line A-A in FIG. Tanibe 3 located in
．． 3, the ring 8 will not slide to one side.

However, if the lighting fixture 9 is now hung tilted due to unbalanced weight, after fixing the lowermost ring 8 by hand as shown in FIG.
'If you rotate it, the ring 8 will move one pitch horizontally beyond the peak 2 as shown in Figure 6, and then move 90 degrees in the opposite direction.
Since each rotation horizontally moves one pitch, it can be horizontally moved to an appropriate position by simply rotating 90' in opposite directions alternately.

At this time, even if the main body 9a is fixed and the ring 8 is rotated by 90 degrees, the ring 8 can be moved in the horizontal direction.

On the other hand, the connection between the arm 10 and the lamp 11 is generally the 10th
This was done as shown in Figures a, b, and c.

That is, a metal hanger 19 is attached to the lower end surface of the pipe-like arm 10 with a shaft 20 that penetrates the arm 10, and the hanger 19 is hooked to a hook 21 provided protruding from the upper surface of the lamp 11, and the screw 22 is attached to the metal hanger 19. It is screwed on.

Further, electrical connection is made by connecting a female connector 24a provided at the tip of a lead wire 23 passing through the pipe-like arm 10 to a male connector 24b opening on the top surface of the lamp 11.

In the figure, 25 is a ballast, 26 is a glow socket, and 27 is a decorative tube.

However, in this example, the shape of the hanger 19 is complicated and the parts cost is high, and the pipe-like arm 10 has a lead wire 23.
is penetrated, so that the shaft 20 is not inserted through the hole 28, and a gap is likely to occur between the hanger 19 and the lower surface of the arm 10 due to misalignment of the insertion hole 28 of the shaft 20, and the lamp 11 tends to wobble. There is a risk that the lamp 1
During installation, the decorative tube 27 must be moved up and down, making the work cumbersome.

Therefore, the lighting equipment of the present embodiment has a structure that allows easy connection without using the hanger 20, as shown in FIGS. 7 to 9.

That is, a beading part 29 is provided at the lower part of the pipe-like arm 10, and a threaded part 30 is provided below the beading part 29.

Thereafter, the decorative cylinder 27 is clamped and fixed with the beading part 29 using the nut 31.

The decorative tube 27 has a hollow truncated cone shape with a downward opening, and a collar piece 32 with a cross-section shaped like an arrow is horizontally protruded from the lower opening edge, and the lower surface of the collar piece 32 is spaced at a predetermined distance from the lower end surface of the arm 10. l
is located only above.

Furthermore, a pair of tap holes 33 are bored in the bottom surface 32a of the collar piece 32 at substantially symmetrical positions, and a set screw 34 is screwed into the tap holes 33 from below.

This tap hole 33 is arranged at a position offset by an angle θ with respect to the center line m of the decorative tube 27, as shown in FIG.

On the other hand, the upper surface of the lamp 11 has a guide hole 36 corresponding to the lower surface of the arm 10 and a large diameter portion 35a at a position corresponding to both the tap holes 33, and has a slender shape curved along the circumferential direction of the decorative tube 27. A pair of pothole holes 35 having portions 35b are provided.

Thus, the lower end of the arm 10 is inserted into the lamp 11 through the guide hole 36.
The head 3 of the set screw 34 is
4a into the large diameter part 35a of the pothole 35, and then rotate the lamp 11 in one direction, the set screw 34 will be located in the narrow diameter part 35b, and after being prevented from being removed, the set screw 34 will close the arm. The lamp 11 is fixed to the lamp 10.

The reason why both tap holes 33 are shifted by the angle θ is to prevent the lamp 11 from being installed in the opposite direction.

Note that 40 is a stopper.

Thus, in the present invention, an opening with an approximately horizontal upper edge is provided approximately in the center of a flat metal plate, and a hanging metal half is formed in which a plurality of pairs of peaks and valleys are continuous at the same pitch on the upper edge of this opening. The lighting fixtures are hung by attaching the two halves of the hanging bracket together so that the peaks of one half of the hanging bracket correspond to the valleys of the other half of the hanging bracket. The lower hanging metal fitting is shaped so that the lowermost ring of the hanging chain passes through the above opening, and the ring engages with the valley of the rain fitting halves, so that the lowermost ring of the hanging chain is inserted into the opening of the hanging metal fitting. The ring is engaged with the valley part of both hanging brackets, and the hanging bracket is hung at an angle with respect to the ring. Therefore, when changing the hanging position of the lighting fixture, one Float the ring from the valley of the other hanging bracket so that most of the weight of the lighting fixture is supported only by the valley of the other hanging bracket, then fix the ring by hand and turn the hanging bracket upside down relative to the ring. By rotating the ring 90 degrees in the direction of the orientation, the ring can be moved over uneven peaks and stably moved to the adjacent valley. In this way, the ring can be moved horizontally one pitch at a time. Even if the lighting equipment is heavy like a jump rear, there is no need to lift the lighting equipment and move it horizontally, making it easy to balance the lighting equipment.

In addition, multiple pairs of peaks and troughs are provided at the same pitch on the upper edge of the opening, so that the hanging fitting can be constructed simply by pasting together two identically formed hanging fitting halves. Since there is no need to separately create two types of hanging metal halves, the manufacturing process is also simple.
