Description

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

FIG. 1 shows a conventional ceiling-embedded emergency lighting fixture.

In the figure, 1 is a cylindrical main body case that is embedded in an embedding hole 3 of a ceiling plate 2, and is attached to the ceiling plate 2 via a mounting bracket (not shown).

4 is a charger, and a lamp 6 is attached to a socket 5 provided on the bottom surface of the charger.

Reference numeral 7 denotes a storage battery storage case, which is provided in an annular shape around the outer periphery of the charger 4.

8 is a front cover provided in contact with the lower surface of the ceiling plate 2; 9;
is a reflector.

The front cover 8 is attached to the main body case 1 with an attachment spring (not shown).

This type of emergency lighting equipment is powered by a built-in storage battery only in an emergency, that is, during a power outage, and is required to be miniaturized for this purpose.

However, since the battery storage case 7 is arranged around the charger 4, the diameter of the embedding hole becomes too large, which makes it noticeable when viewed from below, resulting in a poor design.

Moreover, since the storage battery storage case 7 is arranged around the outer periphery of the charger 4, the heat of the charger 4 is easily transmitted to the storage battery inside the storage battery storage case 7, which causes a problem that it has an adverse effect on the storage battery such as shortening its lifespan. Ta.

Therefore, it was proposed that a storage battery storage case be placed below the charger.

According to this, the diameter of the embedding hole can be made small and the heat of the charger can be transferred to the storage battery and separated.

However, it was difficult for the air warmed by the lamp to escape upward from between the storage battery and the main body case, and it was still insufficient to prevent the effects of lamp heat.

Furthermore, since the storage battery storage case is disposed in contact with the lower surface of the charger, it has not been possible to sufficiently prevent heat generated by the charger from being transmitted to the storage battery.

Therefore, the purpose of this invention is to provide an emergency lighting device in which the diameter of the embedding hole can be made small, the storage battery is not easily affected by the heat from the charger, and the effect of lamp heat on the storage battery is also reduced. It is to be.

An embodiment of this invention is shown in FIGS. 2 to 9.

and a male connector 39 are provided.

The storage battery storage case 17 has semicircular grooves 25 that penetrate vertically at three places on the outer circumferential surface, and the pull cord 26 of the inspection lighting switch (not shown) provided on the charger 9 has a semicircular shape. It passes through the groove 25 and hangs down.

Furthermore, a light emitting diode 2 for battery monitoring is provided on the bottom surface of the charger 9 in correspondence with the semicircular groove 25 of the storage battery storage case 10.
7 is provided.

The inner wall of the semicircular groove 25 of the storage battery storage case 10 is located between the internal storage batteries 18, and also serves to fix the storage batteries 18 in position.

Further, a battery fixing protrusion 2 is provided on the inner surface of the storage battery storage case 17.
8 is provided.

The front cover 8 is provided with an insertion hole (not shown) for a pull cord 26 of an inspection switch.

A pull ring 29 shown in FIGS. 7 to 9 is attached to the pull cord 26 of the inspection switch.

The pull ring 29 includes a pull ring main body 30 and an indicator ring 31 rotatably attached to the pull ring main body 30.

The display ring 31 is provided with a notch 32 in a part of its circumference, and the number 19 indicating the first two digits of the year in the Western calendar and the letters of the year are displayed on the notch 32. The starting year is indicated.

On the other hand, on the pull ring main body 30, a large number of display numbers are exposed through the notch 32 of the display ring 31 and indicate the last two digits of the year.

The pull ring main body 30 has an engagement notch hole 34 into which an engagement piece 33 crimped to the lower end of the pull cord 26 is fitted, and is detachably attached to the retaining piece 33 .

To install this device, follow the steps below.

First, the main body case 1 is attached to the ceiling plate 2 with bolts, wood screws, or the like.

Next, attach the charger 9 and the storage battery storage case 10 to the mounting piece 2.
They are connected by tightening with the mounting screws 24 of 2 and 23.

The mounting screw 24 is tightened by inserting a driver 36 through the notch 41.

During this connection, when the storage battery storage case 10 is pressed against the bottom surface of the charger 9, the charger 9 and the storage battery storage case 1
The female connector 38 and male connector 39 of No. 0 fit together, and an electrical connection is also established.

The combination of the charger 9 and the storage battery storage case 10 is inserted into the main case 1, and the charger 9 is electrically and mechanically connected to the hook ceiling on the upper end wall of the main case 1.

After this, attach the front cover 8. Pull string 26 pull ring 29
is attached to the drawstring 26 after passing the drawstring 26 through the drawstring insertion hole of the front cover 8.

With this configuration, the following effects can be obtained.

That is, since the charger 9 and the storage battery storage case 10 are arranged one above the other, the diameter of the main body case 1 can be reduced compared to the conventional case shown in FIG. Can be made smaller.

Therefore, the diameter D' of the embedded hole 3 provided in the ceiling plate 2 can be reduced to make it less noticeable.

Furthermore, since the storage battery storage case 10 is arranged below the charger 9, heat generated by the charger 9 is difficult to be transmitted to the storage battery 18.

That is, since the area around the charger 9 is open, the heat of the charger 9 is easily dissipated, and the atmosphere heated by the charger 9 escapes as an upward air current, making it difficult for it to be transmitted to the storage battery 18 below. .

Therefore, it is possible to prevent an adverse effect on the storage battery 18 whose life is significantly shortened due to high temperature.

Furthermore, since an appropriate space is provided between the storage battery storage case 10 and the charger 9 by the annular protruding wall 21 of the storage battery storage case 10, heat transfer to the storage battery 18 can be more reliably prevented. .

Further, this space is used as a space for interconnecting the storage battery storage case 10 and the charger 9 by means of the mounting protrusions 22 and 23.

Therefore, the outer diameter can be made smaller than when the mounting protrusion protrudes outward.

On the other hand, since the semicircular groove 25 is provided in the storage battery storage case 17, the internal storage battery 18 is prevented from rattling during transportation, etc., and disconnection within the storage battery storage case 10 can be prevented.

Furthermore, since the semicircular groove 25 is provided, the light emitting diode 27 for battery monitoring can be easily seen from below.
Moreover, since the pull string 26 of the inspection lighting switch can be immediately pulled out downward, the pull string 26 can be easily pulled, and breakage of the pull string 26 can be prevented.

Furthermore, since the semicircular groove 25 is provided, the air warmed by the lamp 6 can easily escape upward, and can prevent the storage battery 18 from being adversely affected.

The semicircular groove 25 projects inward of the storage battery storage case 10, but since it projects into the gap between adjacent storage batteries 18, it does not interfere with storage of the storage battery in the storage battery storage case 10.

Therefore, the formation of the semicircular groove 25 does not increase the diameter of the storage battery storage case 10.

Further, since the semicircular groove 25 of the storage battery storage case 10 serves as a finger hook, when the charger 9 is attached to the hook ceiling, the attachment by rotation is easy to perform.

If the pull ring 29 of the pull cord 26 shown in FIGS. 7 to 9 is used, the pull ring 29 is removed when installing the device, and the tip of the pull cord 26 is inserted into a hole (not shown) in the reflector 9, etc. can be passed through, making the work easier.

Further, it is sufficient that the pull cord insertion hole provided in the reflector plate etc. has a small diameter.

Since the year of first use is displayed on the pull ring 29, the time for replacing the storage battery 18 can be predicted to some extent.

The lifespan of the storage battery 18 is about 5 to 7 years. As mentioned above,
In the emergency lighting device of this invention, a storage battery storage case is placed below the charger, and the storage battery storage case is provided with grooves that penetrate vertically at multiple locations on the outer periphery, and these grooves are connected to adjacent ones inside the storage battery storage case. Since it protrudes into the gap between the storage batteries, the diameter of the embedding hole can be made small, and the storage battery is not easily affected by heat from the charger or lamp.Furthermore, the groove is also used for positioning the storage battery, and It can be used to insert the pull cord of the inspection switch, and this also allows for a smaller diameter.

Furthermore, an annular wall is provided around the upper edge of the storage battery storage case,
Since it is brought into contact with the charger through this annular wall, the heat generated by the charger becomes even more difficult to be transmitted to the storage battery due to the space within the annular wall.

Moreover, since the charger and the storage battery storage case are connected by the mounting piece placed inside the annular wall, the space inside the annular wall can be used effectively, and the height and outside diameter are increased due to the connection means. This has the effect that it does not become large.
