Description

[Detailed explanation of the idea] This invention relates to lighting equipment.

Conventional irradiation direction-adjustable lighting equipment is shown in Figures 1 and 2.
As shown in the figure, both ends of wires 5 and 6 passed through horseshoe-shaped hanging fittings 3 and 4 are respectively fixed to both ends of both sides of the device body 1, and the middle portions of the hanging fittings 3 and 4 are suspended from the ceiling. It is fixed to the lower end of the wire 7.8.

This lighting fixture can freely change the irradiation direction by rotating the fixture main body 1 in the direction of arrow A, and when you release your hands, both ends of the hanging fittings 3 and 4 and the wire 5 , 6, the instrument body 1 can be held in any desired posture.

However, with such conventional lighting equipment, it is necessary to suspend the fixture body 1 from two places on each side, and the irradiation direction must be adjusted using the entire fixture body 1, which makes the adjustment operation difficult. There was a problem.

Therefore, the purpose of this invention is to provide an irradiation device that only needs to be hung from two locations and that allows easy adjustment of the irradiation direction.

An embodiment of this invention is shown in FIGS. 3 to 5.

That is, as shown in FIG. 3, in this illumination direction-adjustable lighting fixture, the lower ends of the two wires 10 and 11 are fixed at a position rearward from the center of gravity of the fixture body 9 and at a position where balance can be maintained laterally. A guide fitting 12 is fixed to the side of the instrument main body 9 opposite to the wire fixing part when viewed from the center of gravity of the instrument main body 9, and extends toward the rear of the instrument main body 9.
The balancer 13 is attached so as to be movable back and forth (close to and away from the instrument body 9) and can be positioned, and as shown in FIG. The wire 10 is attached to the configured two-pronged hanging metal fitting 15.
．． The upper end of 11 is fixed.

In this case, the balancer 13 includes a U-shaped guide fitting 12 whose end is fixed to the side of the instrument body 9, as shown in FIG.
from above and below through the nylon washers 132.13b to the upper balancer body 13C and the lower balancer body 13d.
Pass the screw 13g through the spring 13e and washer 13f through the holes in the upper balancer body 13C and the nylon washers 13a and 13b, and then insert the screw 13g into the lower balancer body 13d. They are fixed together by screwing into the holes, and are configured to be slidable along the guide fitting 12.

In this lighting fixture, by moving the balancer 13 in the direction of arrow B, the fixture main body 9 rotates in the direction of arrow C, and by adjusting the position of the balancer 13, the irradiation direction can be freely adjusted. By rotating the main body 9 in the horizontal direction (in the direction of the arrow), the hanging fitting 15 also rotates, and the instrument main body 9 can be stopped at any position.

In this way, the heat container device of this embodiment has the device main body 9 in two parts.
Since the balancer 13 is suspended from the main wire 10 and 11 and attached to the side of the instrument body 9 so as to be able to approach and separate from the instrument body 9, the instrument body 9 only needs to be suspended from two places, and the balancer 13 can be attached to the side of the instrument body 9. The irradiation direction can be changed simply by changing the position of the irradiation direction, making it easy to adjust the irradiation direction.

In addition, since the upper ends of the two wires 10 and 11 were fixed to a bifurcated hanging fitting 15 configured to be rotatable in a horizontal plane,
The instrument body 9 can be rotated horizontally.

As described above, the lighting fixture of this invention includes a flange attached to the ceiling surface, a hanging metal fitting that protrudes from the flange so as to be rotatable in a horizontal plane and has bifurcated tips, and this hanging metal fitting. two hanging wires with their upper ends fixed to the tips of the device, an instrument body fixed to the lower ends of the two wires at a position rearward from the center of gravity of the instrument and balanced left and right, and a device fixed to the instrument body. The device is equipped with a guide fitting extending to the rear of the instrument body, and a balancer attached to the guide fitting so as to be movable back and forth and positionable, so that only two hanging points are required, and the position of the balancer can be changed. The irradiation direction can be easily adjusted by simply changing the vertical irradiation direction, and by simply rotating the instrument body, the horizontal irradiation direction can be changed.

Further, since only a horizontal rotation mechanism is required, the configuration is simple, the number of parts is small, and the cost is low.
