FIG. In addition, although the package-type fire extinguisher of FIG. 1 has shown the thing of the foam fire extinguisher which injects a foam-like fire extinguisher as an example, this application is not limited to this. The housing 1 is a box-shaped housing having an opening 1a extending almost entirely on the front surface. The open / close doors 2 on both sides cover the opening 1a on the front surface of the housing 1 in half so as to be freely opened and closed. The fire extinguisher filling container 3 is a tank filled with a foam fire extinguishing agent as a fire extinguishing agent. The fire-extinguishing hose 4 has a shape retaining performance, for example, a rubber hose whose cross section perpendicular to the length direction is a hollow circular shape. A nozzle 5 is connected. The hose storage portion 6 is formed by being surrounded by the partition plate 6 a and the inner walls of the upper side surfaces and the upper surface on both sides of the housing 1, and houses the fire hose 4 and the fire extinguishing nozzle 5.

  The pressurization gas cylinder 7 is a tank filled with a pressurization gas, and the pressurization gas is released by operating the start valve 7 a, and the pressure regulator 9 adjusts the pressure of the pressurization gas. The pressurized gas introduction pipe 10 is a pipe for introducing the pressurized gas into the fire extinguisher filling container 3, and the discharge collecting pipe 11 is connected to the base end of the fire extinguishing hose 4, and is discharged from each fire extinguisher filling container 3. A foam fire extinguishing agent is introduced into the fire hose 4. The lever 5 a of the fire-extinguishing nozzle 5 connected to the tip of the fire-extinguishing hose 4 is a lever that is operated to release fire-extinguishing foam (extinguishing liquid) generated by the foam fire-extinguishing chemical from the fire-extinguishing nozzle 5. The fire-extinguishing nozzle 5 has a low-foaming water discharge section 5b that generates and discharges a low-foaming foam (low foaming), for example, a low foaming ratio of 5 to 20, for example, and a fire extinguishing ratio of 20 to 80, for example. And a middle foaming water discharge part 5c for generating and discharging foam (medium foaming). A hose presser that fixes the fire hose 4 on the bottom surface 1c by inserting the fire hose 4 near the opening 1a side of the center of the bottom face 1c of the housing 1 (see FIG. 1B). A part 8 is provided.

  Although not shown in detail in FIG. 1, the partition plate 6 a has a substantially trapezoidal shape with a narrow front side in plan view, and is between the side surfaces 6 b on both sides and the inner walls of the side surfaces of the opposing housings 1. A space S is provided. The partition plate 6a is not limited to a substantially trapezoidal shape as long as the front side is narrow in plan view. For example, the side surface may be formed in a circular arc shape, and the side surface may be formed by a plurality of surfaces.

  The fire-extinguishing hose 4 is first lowered downward from the base end connected to the discharge collecting pipe 11 and is fixed on the inner wall of the bottom surface 1 c by being inserted into the hose holding portion 8. The fire hose 4 inserted through the hose holding portion 8 is then rotated clockwise when the casing 1 is viewed from the opening 1a side, as shown in FIG. 1 (a), for example, from the bottom 1c. Next, it rises along the inner wall on the left side surface and reaches the hose storage 6. And it winds in order in the opening 1a direction side from the back | inner side clockwise in the hose storage part 6 enclosed by each inner wall and the partition plate 6a of the upper side of both sides of the housing | casing, and an upper surface. And the fire extinguishing nozzle 5 at the tip is housed so as to be inside the wound fire hose 4 wound in the hose storage 6.

  The storing operation of the fire hose 4 will be described in more detail. The case where the user stores the fire hose 4 in the hose housing 6 clockwise will be described. First, the user moves the fire hose 4 raised along the inner wall on the left side surface of the housing 1 to the housing. 1 is inserted into the space S on the left side surface side of 1 and introduced into the hose storage 6, and then inserted into the space S on the right side surface side of the housing 1 to temporarily store the tip side of the fire hose 4 in the hose.

Next, while pressing the extinguishing hose 4 in the hose housing 6 against the back side of the housing 1, hold the tip side of the extinguishing hose 4 outside the hose housing 6 by hand, and the right side surface 6 b of the partition plate 6 a. It is introduced into the hose housing part 6 while sliding on the upper side, and sequentially into the hose housing part 6 surrounded by the upper side surfaces on both sides of the housing 1, the upper surface and the inner walls of the partition plate 6 a in the clockwise direction. It repeats winding in order toward the opening 1a direction side from the back side. Then, the fire extinguishing nozzle 5 at the tip is housed so as to be inside the wound fire hose 4 wound in the hose storage portion 6. At this time, the fire hose 4 is stored in a substantially fixed state in close contact with the inner wall surface of the hose storage portion 6 by its own restoring force.

  Thus, by providing the hose accommodating part 6 in the upper part of the housing | casing 1, the user can accommodate the fire extinguisher hose 4 without overhanging with the user standing. In addition, since the partition plate 6a has a tapered side surface 6b so that the front side is narrower in plan view, compared to a rectangular shape or the like, at the corner portion by the front surface and the side surface 6b of the partition plate 6a, The extinguishing hose 4 is not caught, and the extremity side of the extinguishing hose 4 is easily introduced into the hose storage portion 6. In addition, since the predetermined space S is provided between the side surfaces on both sides of the housing 1, it can be wound and stored counterclockwise as well as clockwise according to the user. it can.

  Next, the case where a fire has occurred will be described. First, the user opens the open / close door 2 and opens the start valve 7a. Then, the pressurized gas from the pressurized gas cylinder 7 is adjusted to a predetermined pressure by the pressure regulator 9 and introduced into each extinguishing agent filling container 3 through the pressurized gas introduction pipe 10. Then, the foam extinguishing agent in each extinguishing agent filling container 3 is introduced into the extinguishing hose 4 through the discharge collecting pipe 11. Next, the operator holds the fire-extinguishing nozzle 5 in his / her hand and pulls out the fire-extinguishing hose 4 from the hose storage portion 6 and approaches the fire occurrence place. At this time, the fire hose 4 is housed in the hose housing 6 so that the fire-extinguishing nozzle 5 is wound inwardly from the back so that the fire-extinguishing nozzle 5 is on the opening side. It can be pulled out smoothly in either direction. In addition, since the partition plate 6a has a tapered side surface 6b so that the front side is narrower in plan view, compared to a rectangular shape or the like, at the corner portion by the front surface and the side surface 6b of the partition plate 6a, The fire hose 4 is not caught and can be fed out of the housing 1.

  Then, the operator operates the lever 5a from a location a little away from the beginning, and discharges the fire-extinguishing foam (low foaming) from the low foaming water discharge part 5b. When the fire is moderated to some extent, the fire is approached and the fire is extinguished by operating the lever 5a to release the fire-extinguishing foam (medium foam) from the middle foaming water discharge part 5c. After the fire is extinguished, the operator closes the start valve 7 a and the lever 5 a and stores the fire hose 4 in the hose storage 6. At this time, since the hose housing part 6 is smaller than the housing 1, the fire hose 4 is easily opened in the hose housing part 6 so that the fire-extinguishing nozzle 5 comes to the opening side (the base end side is the back). It can be stored so as to be wound inwardly in a clockwise direction toward the side. Then, the open / close door 2 is closed.

  Thus, by providing the hose storage part 6 at the upper part of the housing 1 and winding and storing the fire hose 4 including the fire-extinguishing nozzle 5 along the inner wall of the hose storage part 6, the user can The fire-extinguishing hose 4 can be taken out without being overwhelmed while standing. Since the partition plate 6a has a tapered side surface 6b so that the front side is narrower in plan view, the fire hose 4 can be easily pulled out of the housing 1 from the hose storage portion 6.

The structure may be such that the direction changes according to the direction in which the fire hose 4 is pulled out. 2 has a structure in which the longer end of the J-shaped bracket 81 is rotatably fixed to the bottom surface 1c by a nut 82, and the shorter end is not fixed as a free end. . Thereby, the load which bends the fire hose 4 at an acute angle can be absorbed.

  Moreover, as shown in FIG. 3, the thing of the structure which can attach and detach the fire hose 4 may be sufficient. 3A is a top view, FIG. 3B is a side view, and the hose holding portion 8 of FIG. 3 includes a pair of fixing members 83 that are fixed to the bottom surface 1c and through which the fire extinguishing hose 4 is inserted. A bolt 84 that extends between the upper ends of the fixing member 83 and prevents the fire hose 4 from coming off, and a nut 85 that fixes the bolt 84 between the fixing members 83. The bolt 84 is fixed by removing the nut 85. It has a structure that deviates from the member 83. This facilitates maintenance and the like. The bolt 84 and the nut 85 are an example of a connecting member that connects the fixing members 83 in a detachable manner, and may have other configurations.

  Moreover, as shown in FIG. 4, the direction which changes according to the pulling-out direction of the fire hose 4 and the structure where the fire hose 4 can be attached or detached may be used. 4A is a top view, and FIG. 4B is a side view. A structural portion including a pair of fixing members 83, bolts 84, and nuts 85 shown in FIG. 3 is formed on the rotating plate 86. It has a structure that is rotatably fixed to the bottom surface 1c by a support portion 87 of a bolt-nut structure. Thereby, absorption of the above-mentioned load and ease of maintenance are obtained.

  In addition, the installation position of the hose holding part 8 is not limited to the bottom surface 1c of the housing 1, but is a lower part of the housing 1 (a protruding component inside the housing 1 that is lower than the center of gravity of the entire housing 1). It is only necessary that the position is lower than the arrangement position, and a considerable effect is obtained.
