Description

[Detailed Description of the Invention] This invention relates to a gas alarm in which a cord is housed in a housing so that it can be pulled out for the required length.

Conventionally, in gas alarms, excess cords were bundled outside, which was unsightly and risked damage.

This invention was made in order to eliminate the above-mentioned drawbacks. This invention will be explained below with reference to the drawings.

Fig. 1 is a back view of an embodiment of this invention with the lid removed, Fig. 2 is a bottom view of Fig. 1, and Fig. 3 is a sectional view taken along line X-X of Fig. 1. be.

In these figures, 1 is a gas alarm, 2 is a housing of this gas alarm 1, 3 is a lid attached to the back side of this housing 2, and 4 is formed by partitioning a part of the inside of the housing 2. A cord storage part 5 is a power cord, which is stored in the cord storage part 4 when not in use. Reference numeral 6 denotes a plug, and 7 a groove serving as a guide for pulling out the cord 5 from the cord storage section 4 to the outside, which are formed on the surface of the lid 3, that is, on the back side of the casing 2. 8 is a groove formed on the side edge of the housing 2 to match the groove 7; 9 is an external output signal line; 10
A groove for passing the external output signal line 9 is formed in the lid 3 in the same manner as the groove 7, and a groove 11 is also formed on the side edge of the housing 2 in correspondence with the groove 10.
12 is a lid of the cord storage section 4. 13,1
Reference numeral 4 denotes a groove, which is provided above the back surface of the housing 2, from which the cord 5 and the external output signal line 9 can be drawn out. Accordingly, as shown in FIG.
A notch 17 is formed in the hole.

When using, remove the lid 12 of the cord storage section 4 as shown in Fig. 1, untie the bundled cords 5, take out the required length, and store the excess cord 5 inside the cord storage section 4. It can be stored as is. The cord 5 pulled out is connected to the grooves 7 and 8.
into the lid 3 so that it does not protrude from the surface of the lid 3. After that, the lid 12 is fitted into the cord storage part 4 again.

As shown in Figure 1, the code 5 and external output signal line 9
When pulling the cord downward, the projecting wall 15 is placed upward and the lid 12 is placed over the cord storage section 4. The grooves 13 and 14 are cut off by the projecting wall 15, separating the outside from the cord storage section. 4, and can be used in the same way as in FIG.

Also, when pulling out the cord 5 or external output signal line 9 from above, use the grooves 13 and 14 and
2 is upside down in Fig. 5, that is, projecting wall 1
If the lid 12 is placed on the cord storage part 4 with the lid 6 facing upward, the cord 5 and the external output signal line 9 will pass through the notch 17, and the lid 12 will be placed on the lid 12 without any problem.
The lower part of the cord storage part 4 is closed by a projecting wall 15.

Note that the cord storage section 4 in each of the above embodiments
Needless to say, not only the cord 5 but also the external output signal line 9 may be accommodated.

As explained above, this invention is a gas alarm in which the lid 3 is attached to the back of the housing 2.
A cord storage section 4 is formed by partitioning off a part of the cord storage section 4, and a groove section 7 is formed on the surface of the lid 3 for pulling out the cord 5 from the cord storage section 4 without protruding from the surface of the lid 3. A groove 13 is formed in the upper part to draw out the cord 5 from the cord storage part 4, and a lid 12 that includes a projecting wall 15 that closes the groove part 13 and opens and closes the cord storage part 4 from the back side is attached. It is convenient to store the entire cord, including the cord, in the cord storage part 4, and when in use, the cord 5 can be pulled out as long as necessary to reach the power outlet, and the excess cord 5 can be stored in the cord storage part 4, so it is convenient to use. This makes it possible to reduce the possibility of damage to the cord 5 significantly. Furthermore, since the groove part 13 for pulling out the cord is formed above the housing, the cord 5 can also be drawn out upwardly.
Since it can be closed when not in use, it has practical effects such as preventing dust from entering.
