[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, specific contents of the present invention will be described based on an embodiment shown in FIGS. FIG. 1 shows a first embodiment of the present invention, which comprises a container body 1 filled with a fire extinguishing agent, and an operation head 3 for radiating a fire extinguishing agent (not shown) in the container body 1 to the outside. The container body 1 is made of a material such as a flexible resin material such as rubber or urethane, and is formed of a bottomed cylindrical body having elastic contraction force. It has a mounting portion 2 provided with a screw portion (not shown).
[0011]
The container body 1 may be a tube having both ends opened to improve workability and reduce costs. In this case, one end of the tubular container body 1 is attached to the operation head, and the lower end of the other end is closed by a closing means to be used as a bottomed container.
[0012]
Specifically, as shown in FIG. 3, the bottom of the other end of the tube-shaped container body 1 is closed by a suitable closing means to form a container with a bottom. For example, a plug having a plug 13 inserted into the bottom opening and a tightening band 14 for airtightly tightening and fixing the plug to the plug from the outer periphery of the bottom of the container body can be used.
[0013]
The operation section 3 is made of a metal material such as a casting, and has a valve mounting section 4 having a valve stem 6 having a valve 6a at a lower end penetrating a lower end thereof, and a free end through a pin 5a at an upper end. It has an operation lever 5 that can be moved up and down, and the upper end of the valve rod 6 is rotatably mounted at a position near the pin 5a of the operation lever 5.
[0014]
In the drawing, reference numeral 8 denotes a radiation hose having one end attached to the valve attachment portion 4. In this configuration, when the fire extinguishing agent is filled in the container body 1 and inflated (see the solid lines in FIGS. 1 and 2), the valve 6a is pressed against the inner surface of the valve mounting portion 4 and is hermetically sealed by an O-ring 7 such as rubber. While being held, the container main body 1a after the emission of the fire extinguishing agent contracts into a shape indicated by a chain line in FIGS.
[0015]
FIG. 4A shows a second embodiment of the present invention. In this case, the container body 1 is made of a relatively flexible material, for example, rubber or nylon, and has a capacity corresponding to the amount of the extinguishing agent previously filled, and the bottom opening is closed and the bottom of the container body 1 is closed by a suitable crimping means. The elastic body having elasticity (for example, a rubber tube) 9 is put on the head body 3 and the container body 1 is filled with a fire extinguishing agent and inflated as shown in FIG. The operating lever 5 is operated to radiate the fire extinguishing agent in the container body to the outside. Note that the shape of the container body 1 after the radiation is as shown in FIG.
[0016]
FIG. 5A shows a third embodiment of the present invention. In this case, the same container body 1 as that of the first embodiment is used, and a metal spring material 11 wound spirally is used as an elastic body having a contractive force, which is put around the container body 1. The head unit is mounted along the outer peripheral surface of the container unit 1 and filled with a fire extinguishing agent from the opening of the mounting unit 2 to fill and inflate the container body 1 against the contraction force of the spring material 11. 3, the operating lever 5 is operated to open the above-mentioned opening of the mounting portion 2, and the internal fire extinguishing agent is radiated to the outside by the contracting force of the spring material 11. The shape of the container main body 1 after emitting the fire extinguishing agent is as shown in FIG. 5 (B).
[0017]
FIG. 6A shows a fourth embodiment of the present invention. In this case, the container main body 1 is configured to be extendable and contractible in the length direction (height direction) of the container by a bellows structure, and the outer peripheral surface of the container body 1 is always provided with a biasing force in the contraction direction. Of spring materials 12 are arranged along.
[0018]
However, the container body 1 is filled with the fire extinguishing agent from the opening of the attachment portion 2 and is attached to the head portion 3 in a state of being filled and expanded against the contraction force of the spring member 12 in the vertical direction. Is operated to open the above-mentioned opening of the mounting portion 2, and the internal fire extinguishing agent is radiated to the outside by the contracting force of the spring material 12. In addition, the shape of the container main body 1 after emitting the fire extinguishing agent is as shown in FIG. 6 (B).
[0019]
In the configuration of each of the above-described embodiments, when the operation lever 5 of the operation head 3 is operated to open the opening of the container body 1 filled with the fire extinguishing agent, the container body 1 having elastic contraction force or the surroundings is opened. The container body 1 covered with the elastic body 9 or 11 or 12 having a contracting force contracts and the content of the fire extinguishing agent is sent to the operation head 3 by pressure, and further from the operation head 3 to the outside by the radiation hose 8. It is radiated toward.
[0020]
【The invention's effect】
As described above, the present invention comprises a container main body filled with a fire extinguishing agent, and an operation head for radiating the fire extinguishing agent in the container main body to the outside, and the container main body is constituted by a cylindrical body having elastic contraction force. Alternatively, since the container body is covered with an elastic body having a contracting force, the structure is simple and inexpensive, and moreover, reliable radiation of the fire extinguishing agent in an emergency can be obtained. Furthermore, since a high-pressure gas cylinder or the like is not used, there is no accident such as explosion of the container, and the safety is excellent.
[0021]
Further, since a tubular cylindrical body having both ends opened and having elastic contraction force is used as the container body, the processing of the container body is easy, suitable for mass production, and low cost can be realized.
