  An embodiment of the present invention will be described with reference to FIGS. 1 to 5 by taking as an example a case where the present invention is applied to a pressurized fire extinguisher having a pressurizing source such as a pressurizing gas cylinder in a fire extinguisher container. As will be described later, the present invention can also be applied to a pressure-accumulating fire extinguisher in which a pressure source such as compressed gas is enclosed in a fire extinguisher container.

  The fire extinguisher 1 is connected to a fire extinguisher container 2 in which a predetermined fire extinguisher is stored, a fire extinguisher container 2 and a hose 3, a discharge port 4 for discharging the fire extinguishing agent, and a discharge port 4 from the fire extinguisher container 2. And an operation unit 5 for starting the supply of the extinguishing agent.

  In addition, this fire extinguisher 1 is a pressurization type, and as shown in FIG. 3, in addition to the discharge pipe 6 for discharging the extinguishing agent into the extinguishing agent container 2, as a pressurizing source A pressurization gas cylinder (containing nitrogen gas or the like) 7 and a gas introduction pipe 8 for introducing the gas in the pressurization gas cylinder 7 into the extinguishant container 2 are provided.

  The operation part 5 is provided on the upper part of the extinguishant container 2 so as to be rotatable about a horizontal axis. Specifically, the base part 5b is pivoted around the horizontal axis by the pivot part 5a on the lid part 2a of the extinguishant container 2. It is supported so as to be rotatable (around an axis orthogonal to the longitudinal axis).

  Moreover, the operation part 5 equips the inside with the communicating path 5c for making the fire extinguisher container 2 and the hose 3 communicate at the time of fire extinguishing. In the present embodiment, the communication path 5c is provided through the base 5b in a direction orthogonal to the longitudinal axis of the operation section 5, and one end 5d is provided. The hose 3 is always connected to the base, and the other end 5 e is opened to the outside of the operation unit 5.

  And the operation part 5 rotates around a horizontal axis, a position (first position) where the fire extinguisher container 2 and the hose 3 are not communicated, and a position (second position) where the fire extinguisher container 2 and the hose 3 are communicated. It is possible to move between these positions. Specifically, as shown in FIG. 1, in a standing state, the position where the extinguishant container 2 and the hose 3 are not communicated (the position of FIG. 1A) is the direction of the arrow A1 around the horizontal axis. The fire extinguisher container 2 and the hose 3 can be moved to a position where the fire extinguisher container 2 and the hose 3 communicate with each other (position shown in FIG. 1B). At this time, as shown in FIG. 3, the communication path 5c is connected to the hose 3 and the extinguishing agent container 2 from the position where the communication path 5c does not communicate the hose 3 and the extinguishing agent container 2 (position shown in FIG. 3A). It can move to the position (position of FIG.3 (b)) which communicates.

  Accordingly, the operation unit 5 is normally in a position where the extinguishant container 2 and the hose 3 do not communicate with each other and does not release the extinguishing agent from the discharge port 4. When the fire extinguisher container 2 and the hose 3 are communicated with each other, the supply of the fire extinguisher from the fire extinguisher container 2 to the hose 3 is started, and the fire is extinguished from the discharge port 4. The agent is to be released.

  The operation unit 5 is normally restricted by a restricting member (safety member) so that the operation unit 5 is held upright, that is, held in a position where the hose 3 and the extinguishant container 2 do not communicate with each other. When the fire is extinguished, the restriction by the restricting member is released, so that it can be rotated in a tilted state. As a restricting member (safety member) for restricting the rotational movement of the operation unit 5, for example, as shown in FIG. 1A, the restricting member (safety member) is always mounted around the base 5b provided with the shaft support 5a. Thus, the rotational movement of the operation unit 5 can be limited, and at the time of fire extinguishing, an annular member 5f (shown by a broken line for convenience of drawing) that is pulled out in the lateral direction and allows the rotational movement of the operation unit 5 can be used.

  Here, in the fire extinguisher 1, as described above, the operation unit 5 rotates around the horizontal axis so that the fire extinguisher container 2 and the hose 3 do not communicate with each other, and the fire extinguisher container 2 and the hose 3 communicate with each other. It is possible to move between the positions. In addition, when the fire extinguisher container 2 and the hose 3 are moved to a position where the fire extinguisher container 2 and the hose 3 are communicated, the fire extinguisher container 2 and the hose 3 are communicated to start supplying the fire extinguisher from the fire extinguisher container 2 to the hose 3. It has become. By doing so, for example, even when the user moves the fire extinguisher 1, even if the user grasps the operation unit 5, the fire extinguishing agent is not released only by that, It is possible to prevent erroneous release of the agent.

  The operation unit 5 in the fire extinguisher 1 of the present embodiment will be described in more detail.

  The operation unit 5 includes a grip portion 5g on the upper portion of the base portion 5b. As shown in FIG. 2, the user can grip the grip portion 5 g and can use it when the fire extinguisher 1 is moved.

  In the present embodiment, the grip portion 5g has a triangular shape with the bottom portion facing upward (when the operation portion 5 is in the upright state, the bottom portion is in a horizontal state, and the user The shape and the like may be changed as appropriate (for example, a circle, a square, etc., or a part of the loop shape may be opened). Good.)

  Further, as shown in FIGS. 3 and 4, when the operation unit 5 moves the communication path 5 c to a position where the fire extinguisher container 2 and the hose 3 communicate with each other, the operation section 5 moves the communication path 5 in the extinguishant container 2. It is configured to connect to the discharge pipe 6.

  Specifically, as shown in detail in the enlarged view of FIG. 4, the insertion portion provided at the upper portion of the discharge pipe 6 of the fire extinguisher container 2 so as to be extended by the elasticity of a spring 6 b (an example of an elastic body). 6a is provided. And when the operation part 5 is located in the state which does not make the communicating path 5c connect the fire extinguisher container 2 and the hose 3, the insertion part 6a of the discharge pipe 6 is pushed down while being closed by the bottom face of the operation part 5. However, when the operating portion 5 moves to the position where the extinguishant container 2 and the hose 3 are communicated with each other, the insertion portion 6a of the discharge pipe 6 is moved to the spring 6b. It is configured to be extended by the elasticity of and inserted into the communication path 5c (state shown in FIG. 4B). A control unit 5h for controlling the movement of the discharge pipe 6 is provided in the communication path 5c, and is fixed at a position where the discharge pipe 6 has moved about halfway to the communication path 5c. Thereby, the operation part 5 will connect the communication path 5c to the discharge pipe 6 in the extinguishant container 2 when the communication path 5c is moved to the position where the extinguishant container 2 and the hose 3 are communicated. Yes.

  As described above, when the operation unit 5 moves the communication passage 5c to a position where the extinguishant container 2 and the hose 3 are communicated, the insertion portion 6a of the discharge pipe 6 is inserted into the communication passage 5c. As a result, the operation unit 5 is fixedly held at a position where the extinguishing agent container 2 and the hose 3 are communicated with each other. The insertion portion 6a is extended by the elasticity of the spring 6b and inserted into the communication passage 5c. However, the entire insertion portion 6a (discharge pipe 6) moves upward and enters the communication passage 5c. It may be inserted.

  Moreover, in the operation part 5, the communication path 5c is provided in the direction orthogonal to the central axis in the longitudinal direction as described above, and one end part 5d is always connected to the base part of the hose 3, and the other end part 5e is opened to the outside, but when the operation unit 5 moves the communication path 5c to a position where the extinguishant container 2 and the hose 3 are communicated, the end of the communication path 5c that is opened. The insertion portion 6a of the discharge pipe 6 is inserted and connected to 5e.

  The open end 5e of the communication passage 5c has a distal end of the insertion portion 6a of the discharge pipe 6 when the operation section 5 moves to the position where the extinguishant container 2 and the hose 3 are communicated with each other. You may make it provide the sealing board broken by.

  The operation unit 5 is configured to open the pressurizing gas cylinder 7 when the operation unit 5 moves through the communication path 5c to a position where the extinguishant container 2 and the hose 3 are communicated.

  Specifically, as shown in detail in the enlarged view of FIG. 4, a pusher 9 for opening the pressurizing gas cylinder 7 is provided in the extinguishant container 2, and this pusher 9 is exposed from the upper part of the lid portion 2a of the extinguishing agent container 2 when the operation unit 5 is located at a position where the communication path 5c does not allow the extinguishing agent container 2 and the hose 3 to communicate with each other. ing. The other end of the insertion portion 9 has a valve body that closes the opening of the pressurizing gas cylinder 7 so that the gas in the gas cylinder 7 flows out when the valve body is pushed. That is, when the operation unit 5 moves to the position where the extinguishant container 2 and the hose 3 are communicated with each other through the communication path 5c, the pressurization gas cylinder 7 is opened by being pushed by the side of the operation unit 5. Yes.

  Note that the distal end portion 9a of the pushing portion 9 of the pressurizing gas cylinder 7 is normally covered with the limiting member 5f shown in FIG. 1 so that it is not pushed inadvertently.

  Next, the hose 3 in the fire extinguisher 1 of this embodiment will be described in more detail.

  The hose 3 is formed so as to be substantially L-shaped, and is provided so as to be able to rotate and move together with the operation unit 5. When the operation unit 5 is in a position where the communication path 5c does not allow the extinguishing agent container 2 and the hose 3 to communicate with each other, the discharge port 4 provided at the tip is directed vertically downward as shown in FIG. It has been provided in a disposition. Further, when the operation unit 5 is in a position where the extinguishing agent container 2 and the hose 3 are communicated with each other through the communication path 5c, the discharge port 4 provided at the tip is set in the horizontal direction as shown in FIG. It is provided with the arrangement which faces to, and is fixed in that state. The hose 3 is made of, for example, a hard material such as plastic, and has such a strength that it is not violated by the discharge pressure of the extinguishing agent.

  In the fire extinguisher 1, the hose 3 is configured as described above, so that the communication path 5 c allows the communication path 5 c to communicate the fire extinguishant container 2 and the hose 3 in order to start the discharge of the fire extinguisher. In conjunction with the movement, the discharge port 4 provided at the tip of the hose 3 can be directed horizontally, and the step of holding the hose 3 horizontally can be omitted. Even if the hose 3 is not gripped, the discharge port 4 can be kept facing the fire source, and the fire extinguisher can be supplied from the discharge port 4 while holding the fire extinguisher container 2 with both hands. For example, even an elderly person with weak power can surely release a fire extinguishing agent toward a fire source.

  Finally, as described above, the fire extinguisher 1 does not release a fire extinguisher just by grasping the operation part 5, and the operation part 5 is provided with a grip part 5g. Thus, for example, as shown in FIG. 5, it is always stored in the fire extinguisher box 10, and at the time of fire extinguishing, the grip part 5 g of the operation part 5 is grasped and taken out from the fire extinguisher box 10 for use. It becomes possible.

  Specifically, for example, the fire extinguisher box 10 is a vertically long box that matches the size of the fire extinguisher 1 and the like, and a front tilt door 11 that is tilted forward and opened on the front surface thereof is provided. Normally, as shown in FIG. 5A, the fire extinguisher 1 is stored in the fire extinguisher box 10, and during fire extinguishing, as shown in FIG. The fire extinguisher 1 can be taken out of the fire extinguisher box 10 and used by tilting and opening the gripping part 5g of the operation part 5.

  In the example shown in FIG. 5, the forward tilting door 11 of the fire extinguisher box 10 includes a window portion 11 a covered with glass or the like so that the inside can be visually observed, a grip opening 11 b for opening and closing, and a fire extinguisher. The side plate 11c for restricting the movement of the vessel 1 (on the left and right sides) is provided.

  As mentioned above, although embodiment of this invention was described based on FIG. 1 thru | or FIG. 5, this invention is not limited by said embodiment, A structure can be changed suitably within the range of the thought of invention. .

  For example, although not shown, the present invention can also be applied to a pressure-accumulating fire extinguisher in which a pressure source such as compressed gas is enclosed in a fire extinguisher container. That is, of course, the configuration of the pressurizing gas cylinder 7, the gas introduction pipe 8, the pushing portion 9 and the like is not necessary. However, if described based on the configuration of the pressurization-type fire extinguisher 1, As a specific change point, the normally closed valve portion that opens the discharge pipe 6 by the extinguishing agent pressure (pressure in the extinguishing agent container 2) at the timing when the insertion portion 6a is inserted into the communication path 5c is further provided. It is possible to apply to the pressure accumulating fire extinguisher of the present invention only by providing it.
