Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an emergency lighting device with a built-in battery that is turned on by an emergency battery built into the device in the event of an emergency.

[Technical background of the invention and its problems]

Conventional examples are shown in FIGS. 1 to 4, respectively. In each of these figures, 1 is a chassis with a U-shaped cross section, 2 and 2 are lamp sockets, 3 and 3 are socket stands attached to both ends of the chassis 1, 4 and 4 are emergency batteries, 5 is a battery holder, and 6 and 7 are clamps. Attachment member 8 is a lighting unit with a built-in ballast and switching circuit, etc.
Reference numeral 9 represents internal wiring within the device, 10 represents a reflector, and 11 represents a fluorescent lamp.

In the case of the conventional example shown in FIG. 1, the internal wiring 9 is provided so as to pass through the center of the chassis 1 in the width direction, and a portion thereof is supported by the battery holder 5. Therefore, before installing the reflector 10,
Not only is most of the internal wiring 9 exposed and hanging down, which is unsightly, but also the internal wiring 9 gets in the way when installing the chassis 1 to the ceiling through the mounting hole provided in the center of the chassis 1 in the width direction. Therefore, there is a drawback that installation workability is poor.

For this reason, as in the conventional example shown in FIG.
A gap with a substantially triangular cross section between the inner surface of one side and the emergency battery 4 in contact with it (same as 13 in Figure 3)
Attempts were made to route the internal wiring 9 through the device. However, since the above-mentioned gap is quite narrow and the wiring is forced there, the internal wiring 9 of the appliance is likely to be caught between the chassis 1 and the emergency battery 4, and this pinching makes the installation state of the battery 4 unstable. In many cases, it was damaged by the edges of the bent edges 1a on both sides of the chassis. For this reason, sufficient care was required when assembling the instrument, and the assembly workability was poor, making it unsuitable for practical use.

Therefore, generally, as in the conventional example shown in FIG. It is now being placed outside. However, this has basically the same drawbacks as the above-mentioned conventional example illustrated in FIG.
The more that is required, the more complicated the work and the higher the cost.

In addition, in the conventional example shown in FIG. 4, the holding part 5a of the battery holding member 5 is shaped like an arc to hold a part of the emergency battery 4, and this and the flat plate part 1b of the chassis 1 are used to hold the emergency battery 4. The structure is designed to mount and support the In this case, a fairly large gap 14 can be secured between the side inner surface of the chassis 1 and the emergency battery 4. However, even if the internal wiring 9 is placed in this gap B, it will hang down and look unsightly.
Moreover, there is a drawback that the reflector plate 10 is easily caught when it is attached. Furthermore, in this conventional example, the presser portion 5a
Since the battery holder 5 is shaped like an arc, the material and processing costs for the battery holder 5 are high, which contributes to high costs, and since the emergency battery 4 is supported only in two places, there is also the disadvantage that the battery holding power is reduced. .

[Purpose of invention]

Therefore, the purpose of the present invention is to facilitate the assembly and installation of the device, and to
To provide a simple and inexpensive emergency lighting device capable of improving chassis strength and battery holding power.

[Summary of the idea]

That is, in the emergency lighting device according to the present invention, an inward projecting edge facing toward the center in the width direction of the chassis is integrally provided at the tip of both bent portions of the chassis, and a circumferential surface is formed at the tip of the inward projecting edge. The emergency batteries, which are placed inside both sides of the chassis with their parts in contact with each other, are pressed and fixed with battery holders that are integrally provided with diagonal holder pieces at both ends of the flat plate part, and the battery holders are pressed and fixed with the battery holders that are integrally provided with diagonal holder pieces at both ends of the flat plate part. A feature is that the internal wiring of the device is passed through the space provided between the inner surfaces of both sides of the chassis.

According to the emergency lighting equipment with this feature, the wiring inside the equipment is not routed to the center of the chassis in the width direction, so the wiring inside the equipment is prevented from getting in the way when installing the chassis to the ceiling. , which can improve installation workability. Since the emergency battery is supported by the inward protruding edges provided on the chassis, the gap secured between the circumferential surface of the battery and the inner surfaces of both sides of the chassis can be increased. Therefore, in wiring work through this gap, the internal wiring of the device can be placed securely within the gap, and there is no possibility that the internal wiring of the device may be caught between the chassis and the battery, making the battery installation state unstable. This prevents the wiring inside the device from being damaged by the edges of the chassis, making wiring work easier.In addition, the inward protruding edge prevents the wiring inside the device from sagging, making it easier to install the reflector. This makes it easier to assemble the device, and the work of bundling the wiring inside the device can also be omitted, making it easier to assemble the device. Furthermore, by providing the inwardly directed flange, the mechanical strength of the chassis can be improved. Since the emergency battery is supported at three locations on the strong chassis as described above, including the flat plate portion, the inward projecting edge, and the battery holder, the battery holding power can be improved. In addition, as mentioned above, the battery holder is easy to assemble and can omit binding tools, and the battery holder has a structure in which slanted holder pieces are integrally provided at both ends of the flat plate part, which reduces the material and processing costs for this holder. Since the cost is reduced and the cost is low, emergency lighting equipment can be constructed at low cost.

[Example of idea]

An embodiment of the present invention will be described below with reference to FIGS. 5 to 7.

In the figure, reference numeral 21 denotes a metal chassis, which has downward bent portions 22 on both sides of a flat plate portion 21a, and inwardly directed edges 23 at the ends of these bent portions 22. It is formed integrally toward the center in the width direction. Although not shown, a mounting hole to the ceiling is provided at the center in the width direction of the flat plate portion 21a, and a ceiling abutting portion 24 is provided in a protruding manner as shown in FIG. A metal socket base 25 is attached to each end of the chassis 21, and a lamp socket 26 is attached to each of these sockets 25.

Emergency batteries 27 are arranged inside both sides of the chassis 21, and these batteries 27
is pressed and fixed by a battery holder 28 with a part of its circumferential surface in contact with the tip of the inward protruding edge 23 . The battery holder 28 is made of metal, and the flat plate part 2
A diagonal holding piece 30 is integrally provided at both ends of the battery holding piece 9, and the battery holding piece 28 presses the emergency battery 27 using tightening members such as a bolt 31 and a wing nut 32.

Furthermore, a lighting unit 33 containing a ballast, a switch, a switching circuit, etc. is attached to the chassis 21. The lighting unit 33 automatically switches the lighting circuit so that the power from the battery 27 is supplied to the emergency lights in an emergency (during a power outage).

Reference numeral 34 denotes an internal wiring that connects the lamp socket 26, the emergency battery 27, and the lighting unit 33, a part of which is secured between the inner surface of both sides of the chassis 1 and the circumferential surface of the emergency battery. It passes through a gap 35.

In the figure, reference numeral 36 denotes a reflector having socket through holes 37 at both ends, which hides the chassis 1 and is adapted to be attached to the socket base 25 with decorative screws 38. Further, numeral 39 in the figure is a straight tube type fluorescent lamp that is detachably attached between the lamp sockets 26, and in this embodiment, it also serves as an emergency light.

In the above structure, since the battery 27 is attached by placing a part of the circumferential surface of the emergency battery 27 against the inward protrusion 23 provided on the chassis 21, the inner surface of both sides of the chassis 1 and the circumferential surface of the emergency battery 27 are attached. A large gap 35 can be secured between the surface and the surface. Therefore, the work of passing the internal wiring 34 into the space 35 becomes easy, and since the internal wiring 34 is prevented from hanging down by the inward protruding edge 23, the work of attaching the reflector plate 36 is simplified. Facilitated. Then, since the internal wiring 34 of the device is housed and supported in the gap 35, the chassis 2
1 to the ceiling, the internal wiring 34 is prevented from getting in the way. Furthermore, since the emergency battery 27 is supported by the flat plate portion 21a of the chassis 21 and the inwardly directed ridge 23, it is sufficient that the pressing piece 30 of the battery holding member 28 has an oblique shape.
There is no need to make the battery holder 7 into an arc shape, and therefore a low-cost battery holder 28 can be used.

In addition, although in the above-described embodiment, the lamp serves both as a regular light and an emergency light, the present invention can also be implemented in an emergency lighting fixture that is provided with these lights separately. In addition, when implementing the present invention, unless it is contrary to the gist of the invention, the chassis, inward flange, emergency battery, battery holder, void,
It goes without saying that the specific structure, shape, position, etc. of the internal wiring of the device is not limited to the one embodiment described above, and can be configured and implemented in various ways.

[Effect of idea]
