Embodiments of the present invention will be described in detail below with reference to the drawings.

The main lower bar 1 and the cross T-bar 1 are formed in a lattice shape,
A ceiling plate 14 is laid in the space formed between both T-bars 1, 1 to form a ceiling.

The T-bar 1 is suspended by a hanging wire 16 from above a field edge or the like.

Reference numeral 2 denotes a mounting bracket to be attached to the T-bar 1. This mounting bracket 2 is composed of a pair of clamping pieces 2□, 2□, and is mounted so as to clamp the T-bar 1 from both sides thereof.

The upper parts of the clamping pieces 20, 2□ are bent inward and brought into close contact with each other above the T-bar 1, and fixed with screws 22.

Recesses 24 and 25 for inserting and locking the lower horizontal piece 23 of the T-bar 1 are formed in the lower portions of the holding pieces 20 and 2□, respectively.

A threaded rod 18 is suspended from the center of the lower surface of the horizontal piece 17 forming the recess 24 in the lower part of one of the clamping pieces 2 .

Horizontal piece 19 forming the recess 25 of the other clamping piece 2□
A slit 20 opening to the side of the holding piece 2 is formed in the center of the holding piece 2, and a vertical piece 21 for preventing detent is bent at the edge of the horizontal piece 19.

Note that slit 20 is for inserting the threaded rod 18.

Since the mounting bracket 2 holds the pair of clamping pieces 20, 2□ facing the side surfaces of the T-bar 1, the mounting bracket 2 is movable in the longitudinal direction of the T-bar 1.

When both the clamping pieces 20 and 2□ are brought together, both ends of the lower horizontal piece 23 of the T-bar 1 are inserted into both the recesses 24 and 25, and the threaded rod 18 is inserted into the slit 20.

Furthermore, the vertical piece 21 of the other clamping piece 2□ is connected to one clamping piece 2,
The clamping piece 2□ is held so that it does not come off.

Reference numeral 4 denotes a support metal fitting having a U-shaped cross section and located below the mounting metal fitting 2, and is composed of a center piece 3 and side pieces 5, 5 on both sides.

The center piece 3 of the support fitting 4 is attached to the lower surface of the mounting fitting 2.

That is, a hole 26 into which the threaded rod 18 is inserted is bored in the center of the center piece 3, and a wing nut 27 is screwed onto the threaded rod 18 that protrudes through the hole 26 to attach the support metal fitting 4.
can be attached to the bottom surface of the mounting bracket 2.

The lower end portions of both side pieces 5, 5 are shaped like locking pieces 6, 6, which are formed on the outside and are bent into a substantially semicircular shape with their tips facing upward.

Further, a stopper claw 7, which is located at the lower end of both side pieces 5, 5 and whose lower end is located above the locking piece 6, is cut and raised to protrude outward.

Since the support fitting 4 is screwed and fixed with the threaded rod 18 as described above, the support fitting 4 is rotatable with respect to the mounting fitting 2, and the support fitting 4 can be fixed in a position in any direction. .

Reference numeral 9 denotes a long main body rail with an open top and a U-shaped cross section. A stabilizer 29 and the like are installed.

In the case of the embodiment, two lamps 8 are provided.

A new bent piece 1 is bent inward and downward over the entire length of the upper end of the rising piece 10 on both sides of the main body rail 9.
2, and the bent piece 12 and the rising piece 10 form a V-shaped groove 11 whose lower surface is open.

The locking piece 6 of the support metal fitting 4 is inserted and locked into this groove 11.

Furthermore, contact pieces 13 are provided horizontally inward from the edges of the bent pieces 12 over the entire length in the longitudinal direction.

When the main body rail 9 is locked to the support fitting 4, the lower end of the stopper claw 7 abuts the upper surface of the abutting piece 13 as shown in FIG. This prevents it from moving and coming off.

Since the mounting structure of the support fitting 4 and the main body rail 9 is such that the locking piece 6 is inserted and locked into the groove 11 as described above, the support fitting 4 can be installed at any position in the longitudinal direction of the main body rail 9. It is.

Further, the length of the main body rail 9 may be determined by the length and quantity of the lighting equipment itself, and may be a single unit or a combination of lights, and a lid 30 may be provided on the opening surface of the main body rail 9 as required.

When installing lighting equipment on the T-bar 1, proceed as follows.

That is, the mounting bracket 2 consisting of a pair of clamping pieces 2 □ and 2 □ is faced to the T-bar 1 and the upper screw 22 is tightened to hold the mounting bracket 2 on the T-bar 1 .

Next, the locking piece 6 of the support metal fitting 4 is slid into the groove 11 of the main body rail 9.

At this time, the stopper claw 7 of the support metal fitting 4 hits the abutment piece 13 of the main body rail 9 to prevent it from coming out.

Attach the support bracket 4 combined with the main body rail 9 to the mounting bracket 2
Tighten the wing nut 27 in line with the threaded rod 18.

Note that this order may be reversed so that the support fitting 4 is attached to the mounting fitting 2 and then the main body rail 9 is attached to the support fitting 4.

In addition, since the mounting bracket 2 is movable in the longitudinal direction of the T-bar 1, and the support bracket 4 and the main body rail 9 are movable in the longitudinal direction of the main body rail 9, it is possible to install the lighting equipment after installation. Fine adjustments to the position can be made easily, and changes can also be made easily.

Furthermore, since the support fitting 4 is rotatable, it is possible to change the line by setting the lighting fixture at right angles.

Additionally, the lighting fixtures can be manufactured at low cost using roll homing processing.

Also, inside the main body rail 9, there are a power supply line 31 and a crossover line 3.
2 can be easily stored.

As described above, the present invention attaches a mounting bracket composed of a pair of clamping pieces to a T-bar that supports a ceiling plate so as to be movable in the longitudinal direction of the T-bar, and the support bracket has a U-shaped cross section. The pieces are rotatably attached to the lower surface of the mounting bracket, and the lower ends of both sides of the support bracket are provided with locking pieces whose tips are bent upward and laterally, and the lower ends of the support bracket are provided with the locking pieces bent upward and laterally. A stopper claw is provided above each of the locking pieces, an illumination lamp is provided on the lower surface, the upper surface is open, and the upper ends of the rising pieces on both sides of the main body rail of a long object having a U-shaped cross section extend over the entire length in the longitudinal direction. Each of the bending pieces has a groove with an opening on the bottom surface which is folded downwardly and into which the locking piece of the support metal fitting is inserted movably in the longitudinal direction of the main body rail.
A contact piece whose upper surface abuts the lower end of the stopper claw is provided horizontally from the edge of the bent piece over the entire length in the longitudinal direction, and the locking piece of the support metal fitting is inserted into the groove of the main body rail. At the same time, the lower end of the stopper claw of the support metal fitting is brought into contact with the upper surface of the abutment piece of the main body rail, so that the T-bar and the mounting metal fitting, and the support metal fitting and the main body rail move respectively. Because it is flexible, the position of the lighting fixture can be freely moved to the appropriate location, as well as finely adjusted through the groove in the main body rail, and the number of mounting brackets can be rationalized depending on the strength of the main body rail and T-bar. It also has the advantage of being able to easily change the line of lighting fixtures by rotating the support metal fittings at right angles, and is easy to assemble by inserting and locking the support metal fittings into the main body rail. Furthermore, since the top surface of the main body rail is open, it has the advantage that power supply lines and crossover lines can be easily stored.
