Description

[Detailed explanation of the invention] This invention relates to the improvement of a fire extinguisher that is installed in ordinary homes to provide initial extinguishing of fires, and is designed to ensure that the nozzle always faces in a fixed direction when it is hung from a pillar, etc. The aim is to provide a fire extinguisher that can

For example, as a small fire extinguisher installed in a general household etc. for use in the initial extinguishing of a fire, as shown in Figs. There is a structure in which 3 is adhered and fixed.

When using a fire extinguisher, point the nozzle 2 at the source of the fire and hit the activation button 4 provided on the top surface of the lid 3. This will break the seal of the pressure gas cylinder attached to the bottom of the lid 3, causing the container 1 to explode. The extinguishing agent inside is pushed by the pressure gas and is injected from the nozzle 2 toward the source of the fire.

Incidentally, a small fire extinguisher constructed and operated in this manner is often hung in a place where it does not get in the way, such as on the side of a pillar, when not in use.

For this reason, conventionally, as shown in FIGS. 1 and 2, a bracket 5 is fixedly installed on the upper side surface of the container 1, and this bracket is locked to a hook 6 fixed to the side surface of a pillar or the like. A fire extinguisher was hung on the side of a pillar, etc.

However, when a fire extinguisher is suspended using such a structure, the following inconvenience occurs.

In other words, in a fire extinguisher that has a structure in which the lid 3 is screwed directly onto the container mouth using screws carved around it, this When the lid 3 is screwed onto the container opening and tightened, the positional relationship between the lid 3 and the container 1 is not always constant.

On the other hand, the bracket 5 is fixed to the upper side of the container 1 by means such as welding before filling the container 1 with extinguishing agent and attaching and fixing the lid 3 to the mouth of the container 1. The direction of the nozzle 2 when suspended is not constant.

For this reason, as shown by the solid line in Figure 2, when the bracket 5 and nozzle 2 are located at almost right angles to the center of the fire extinguisher, the fire extinguisher can be removed from the pillar and firefighting operations can be carried out immediately. On the other hand, if the nozzle 2 is located at the position shown by the chain line in the figure, the fire extinguisher cannot be started unless it is removed from the pillar and held so that the nozzle faces in the specified direction, and the fire extinguisher cannot be started. In some cases, the start of firefighting operations may be momentarily delayed.

The fire extinguisher of the present invention eliminates the above-mentioned disadvantages.

Hereinafter, the present invention will be explained with reference to drawings showing embodiments.

FIG. 3 shows the overall configuration of the fire extinguisher of the present invention.

A lid 3 is screwed and fixed to the upper opening of a container 1 filled with a fire extinguishing agent using a stud carved into the lid 3.

The lid 3 is provided with a nozzle 2 and an activation button 4, similar to the conventional fire extinguisher shown in FIGS. 1 and 2.

Furthermore, a bracket 7 as shown in FIG. 4 is fixed to the upper corner of the lid 3. As shown in FIG.

This bracket 7 is made by bending a metal plate with sufficient rigidity into an L-shape, and forming a pot-shaped locking hole 8 with a small diameter at the top and a large diameter at the bottom in the vertical plate part 7a, and a locking hole 8 in the corner of the horizontal plate part 7b. The screws 10 and 10 (Figures 3 and 5) inserted into the holes 9 and 9 are inserted into the screw holes formed on the top surface of the lid 3 ( The screw 10 may be a self-tapping screw or may be a simple circular hole.

) and tighten it to fix it to the top surface of the lid body 3.

At this time, the nozzle 2 and bracket 7 should be in a positional relationship that allows fire extinguishing operations to be carried out immediately after removing the fire extinguisher from a pillar, etc. For example, the nozzle 2 and bracket 7 should be at a nearly right angle to the center of the fire extinguisher. .

When hanging a fire extinguisher configured in this way on a pillar, etc.,
As shown in FIGS. 3 and 4, the head 11 a passes through the large diameter portion in the lower half of the locking hole 8 but cannot pass through the small diameter portion in the upper half.
Screw a screw 11 having a shape into the side of a pillar or the like with the head 11 a slightly lifted from the side, and hook the locking hole 8 of the bracket 7 onto the head 11 a of the screw. Hang the fire extinguisher from the side of a pillar, etc. as shown in Figure 6.

When using a fire extinguisher, the fire extinguisher can be easily removed by lifting it slightly and used for fire extinguishing work.

In this case, since the nozzle 2 and the bracket 7 are both fixed to the lid 3, the nozzle 2 and the bracket 7 are fixed no matter how the angle of attachment of the lid 3 to the container opening changes. Since the positional relationship with the fire extinguisher is constant, the fire extinguisher can always be hung in the optimal position.

It is also effective because it eliminates the trouble of manufacturing the container opening and lid with a constant threading condition.
