And a battery box. The height B from the frame to the rear of the device box is shorter than the length A of the battery box, and the battery box is configured to be inclined with respect to the frame when the battery is taken out.

[0009]

According to the emergency lighting device mounted on the mounting hole of the ceiling, the height B from the frame to the rear portion of the equipment box is formed shorter than the length A of the battery box, so that the battery is taken out. When the battery box comes into contact with the frame, the rear upper surface of the battery box contacts the rear of the equipment box, and when the battery box is opened with the battery box tilted, the battery Slides out and the battery can be easily replaced.

[0010]

1, an emergency lighting apparatus 1 according to the present invention includes a main body 2 and a battery box 3, and a flexible electric wire having an electric wire passing between the main body 2 and the battery box 3. Tube 2a is connected. The main body 2 has a frame 6 attached to a mounting hole in the ceiling, and two support members 5 are provided so as to stand up from the frame 6 at an interval. The equipment box 4 is attached between the support members near the upper end of the support member 5, and a ballast, a socket, and the like are arranged in the equipment box 4. The bowl-shaped reflector 7 having an opening at the bottom is inserted into the frame 6 from below and arranged between the support members 5. A lamp such as a compact fluorescent lamp is disposed in the reflector 7.

[0011] As shown in FIG.
A battery storage unit 9 in which the battery 8 is stored and a device storage unit 11 in which a device 10 such as an inverter is stored are provided. A door 12 that slides up and down is provided at a front entrance of the battery storage unit 9. 12a is a screw for fixing the door 12.

A battery holder 9 has an inclined table 13, and the battery 8 is placed on the table 13. The battery 8 is a wire 15 with a connector 14
Is connected to the device 10 in the device storage unit 11. Also, the rear upper surface 3a and the front lower surface 3 of the battery box 3
Projections 16 and 17 as positioning members are provided on b.

As shown in FIG. 3, the frame 6 has a circular shape, for example, and has a flange 6a mounted in the mounting hole 21 of the ceiling material 20.
And a rising portion 6b, and the rising portion 6b is provided with a cutout portion 6c cut out by a width substantially equal to the width of the battery box 3. It should be noted that the presence of the notch 6c facilitates positioning, but need not be provided.

The length A of the battery box 3 and the length of the main body 2
From the frame 6 (from the notch 6c when there is the notch 6c) to the lower surface of the rear portion 4a of the device box 4, the relation B <A.

[0015] The emergency lighting fixture 1 is attached to the mounting hole 2 of the ceiling material 20.
In order to attach the battery box 3 to the battery box 3, the battery box 3 is first inserted into the ceiling from the mounting hole 21, then the main body 2 is inserted into the mounting hole 21, and the frame 6 is fixed to the periphery of the mounting hole 21 by screwing. Finally, the reflector 7 is inserted into the frame 6 from below, and is fixed between the support members 5 using the stoppers 5a.

In order to replace the battery 8, the reflector 7 is first removed, and then a hand is inserted from the frame 6 to pull the battery box 3 out.
However, since the length A of the battery box 3 is longer than the height B from the notch 6c of the frame 6 of the main body 2 to the rear portion 4a of the device box 4, the length A is near the rear upper surface 3a of the battery box 3 as shown in FIG. Is in contact with the rear part 4a of the equipment box 4, while the front lower surface 3b of the battery box 3 contacts the notch 6c of the frame 6, so that the battery box 3 is inclined and cannot be pulled out any further. At this time, the protrusions 16 and 17 of the battery box 3 are in contact with the rear portion 4a of the device box 4 and the protrusions 17 are in contact with the notches 6c of the frame 6, so that the battery box 3 functions as a positioning member. It will be positioned at that oblique position.

In this state, the screws 1 of the battery box 3
If you loosen 2a and slide the door 12 upward to open it,
Since the battery box 3 itself is slanted and the battery 8 is placed on the slanted table 13, the battery 8 slides out of the battery box 3. Separated at the connector 14, the battery 8 is disconnected from the electric wire 15, a new battery 8 is connected, and the new battery 8 is placed in the battery box 3 while the battery box 3 is again inclined or kept horizontal, The door 12 is closed. Thereafter, the battery box 3 is returned to the original position above the ceiling, the reflector 7 is attached, and the battery replacement operation is completed.

When the battery box is inclined, the vicinity of the rear upper surface 3a of the battery box 3 is located near the equipment box 4.
It is not necessary to tilt the battery until it comes into contact with the rear part 4a. It is easier to take out the battery if the holder 13 is provided, but it is not always necessary to provide the battery box because the battery box itself is inclined. . Also, the rear part 4 of the equipment box 4
A positioning member for positioning in cooperation with the positioning member on the battery box 3 side may be provided near a.

[0019]

[Effect of the Invention] Since the height from the frame of the main body to the rear of the equipment box is shorter than the length of the battery box, the battery box cannot be pulled out through the frame, but the battery box cannot be pulled out. Since the battery slides out in an oblique state, the battery can be replaced without removing the battery box from the mounting hole in the ceiling, and the replacement operation of the battery can be completed easily and in a short time.
