EXAMPLES Next, examples of the present invention will be described. FIG.
FIG. 2 is a side sectional view showing an example of the emergency lighting device according to the present invention, and FIG. 2 is a plan view. Note that FIG. 1 is a sectional view taken along the line AA ′ of FIG. These drawings show a state in which the emergency lighting device is attached to the ceiling of the building, and 9 is a ceiling plate that forms the ceiling. As shown in FIG. 2, a rectangular ceiling notch 9a is formed on the ceiling plate 9. The plate 3 constituting the emergency lighting device of the present invention is slightly smaller than the ceiling notch 9a, but has substantially the same shape and size.
The thickness of the board 3 is the same as the thickness of the ceiling board 9. The material of the plate 3 may be the same as a general ceiling material, and various materials such as wood, plastic, metal, and composite material can be used. The downlight 1, which is an emergency lighting fixture, is mounted on the plate 3 and thus on the back side of the ceiling. This downlight 1 has an incandescent light bulb 1b,
Are housed in a cubic transparent case 1a. The electric bulb 1b is connected to an emergency power source (not shown) including, for example, a battery by the electric wire 1c, and is supplied with electric power through the electric wire 1c in the event of a power failure.

A through hole 3f is formed between the parallel side ends 3a and 3b of the rectangular plate 3 to connect them. The position of the through hole 3f is in the middle of the other parallel side end portions 3c and 3d. At the position of the ceiling plate 9 corresponding to the through hole 3f,
The bearing fittings 10 are installed so as to face each other and are embedded in the ceiling plate 9. The metal shaft 2 has a through hole 3f in the plate 3.
And is attached to the ceiling plate 9 by the bearing fitting 10. Therefore, the plate 3 is attached to the ceiling plate 9 by the shaft 2 so as to be rotatable about the shaft 2.
The center of gravity of the plate 3 including the downlight 1 is set at a position displaced in the horizontal direction from the shaft 2 so that the plate 3 rotates about the shaft 2.

A U-shaped first fixture 7 is screwed to the end of the plate 3 with the open side of the U-shaped facing outward. Reference numeral 6 denotes a solenoid fixed to a predetermined position on the ceiling plate 9 corresponding to the fixture 7. Reference numeral 8 is a driving piece of which the tip is the second fixture of the present invention, and the tip is normally engaged with the fixture 7 as shown in the figure. The solenoid 6 has a built-in spring, and the driving piece 8 is fixed by the spring to the fixing member 7 indicated by an arrow A.

An inspection hole 5 is also formed in the plate 3 so that the lighting of the downlight 1 can be confirmed when the downlight 1 is housed in the ceiling.

Next, the operation will be described. In a normal state, the solenoid 6 is supplied with power from a power source for normal illumination of, for example, AC100V, the driving piece 8 overcomes the force of the built-in spring and is pushed out in the direction opposite to the arrow A, and its tip is fixed. The tool 7 is engaged. Therefore, the plate 3 does not rotate and maintains the state shown in FIGS.

If a power failure occurs here, power supply to the solenoid 6 is stopped. As a result, the force pushing the drive piece 8 in the direction opposite to the arrow A disappears, and the drive piece 8 moves in the direction of arrow A by the force of the built-in spring until the tip reaches the position of the dotted line. As a result, the engagement state between the fixture 7 and the drive piece 8 is released. The center of gravity of the plate 3 including the downlight 1 is set at a position horizontally displaced from the shaft 2 so that the plate 3 rotates about the shaft 2, so that the plate 3 rotates in the direction of arrow B, for example. , Plate 3 is 18
Rotated by 0 degrees, the downlight 1 is, as shown in FIG.
Go out from the ceiling to the front. And the electric wire 1c is attached to the light bulb 1b.
Power is supplied from the emergency power source through the bulb 1b, and the bulb 1b is turned on to function as an emergency lighting facility.

Further, such emergency equipment needs to be regularly inspected, but in this emergency lighting device, the string 4 and the hole 5 are used.
To do that. In other words, with the downlight 1 stored in the ceiling, pull the string 4 to light it,
Confirm that it is lit through the hole 5. Therefore, at the time of inspection, it is not necessary to rotate the plate 3 and take out the downlight 1 to the front side.

It should be noted that the electric wire 1c may be provided by loosening it in advance in consideration of the amount of rotation of the plate 3, but, for example, the shaft 2 is made of a hollow member and is inserted into the shaft 2. You may arrange by doing. Further, in the present embodiment, the driving piece 8 of the solenoid 6 also serves as the second fixture of the present invention, but this is merely an example. It is of course possible to provide another fixture that engages with the fixture 7 and move it by the drive piece 8.
