FIG. 2 is a front view of the fire extinguisher main body according to the embodiment of the present invention with the open / close door opened. In addition, although the thing of the foam fire extinguisher which injects a foam-like fire extinguisher is shown as an example for the fire extinguisher main body of FIG. 2, this application is not limited to this.
The fire extinguisher main body 2 has a box-shaped housing 4 having an opening 31a extending almost entirely on the front surface, and covers the opening 31a on the front surface of the housing 4 so that it can be opened and closed. An opening / closing fulcrum 32a is the front surface of the housing 4 Viewed from the side to the back side (= viewed from the front side of the housing) (direction from the front side to the back side of the paper: hereinafter, the left and right and hose winding directions are those seen from this direction) The open / close door 32 is provided on the right side (the side opposite to the hose storage box 36).

  The fire extinguisher main body 2 is a fire extinguisher filling container 33 which is a tank filled with a foam extinguishing agent as a fire extinguishing agent, a shape-holding performance, for example, a rubber hose having a hollow circular shape in a cross section perpendicular to the length direction, A fire extinguishing hose 34 having a proximal end connected to the extinguishing agent filling container 33 side and supplied with the extinguishing agent is connected to the distal end of the fire extinguishing nozzle 35. A fire extinguishing hose 34 is provided on the left side of the housing 4. And a hose storage box 36 for storing the fire-extinguishing nozzle 35.

The fire extinguisher main body 2 includes a pressurizing gas cylinder 37 that is a tank filled with a pressurized gas, a pressurized gas introduction pipe 40 that is a pipe for introducing the pressurized gas into the fire extinguisher filling container 33, and a fire hose 34. And a discharge collecting pipe 41 for introducing the foam extinguishing agent released from each extinguishing agent filling container 33 into the extinguishing hose 34.
The pressurization gas cylinder 37 releases the pressurization gas by operating the start valve 37 a, and the pressure regulator 39 adjusts the pressure of the pressurization gas.
The lever 35a of the fire-extinguishing nozzle 35 connected to the tip of the fire-extinguishing hose 34 is operated to release fire-extinguishing foam (extinguishing liquid) generated by the foam fire-extinguishing chemical from the fire-extinguishing nozzle 35.
The fire-extinguishing nozzle 35 has a low-foaming water discharge part 35b that generates and discharges a low-foaming foam (low foaming), for example, a foaming ratio as low as 5-20, and a fire extinguishing ratio, such as a foaming ratio, as relatively high as 20-80. And a middle foaming water discharge portion 35c for generating and discharging foam (medium foaming).

  The hose storage box 36 is formed in a box shape having an open front, a hose introduction notch 36c is formed on the upper wall thereof, and a notch 36a for smoothly pulling out the fire hose 34 on the lower side of the right side wall. Further, a hose introduction notch part 36c and a notch part 36a and a turn-back part 36b for preventing the fire hose 34 from protruding from the opening part except the bottom wall part are provided in the opening on the front surface. Is formed. The notch 36a has a trapezoidal shape with a width that increases toward the opening. The hose storage box 36 is disposed on the left side surface of the housing 4, which is opposite to the opening / closing fulcrum 32 a of the opening / closing door 32. A fire extinguisher filling container 33 having a substantially circular horizontal cross section is disposed on the right side of the hose storage box 36, and a pressurizing gas cylinder 37 is disposed on the right side thereof.

  The fire-extinguishing hose 34 is introduced into the hose storage box 36 from the notch 36c for hose introduction, and is wound and housed in an inner winding counterclockwise from the back side of the hose storage box 36 toward the opening side. Yes. At this time, the fire-extinguishing hose 34 is in a substantially fixed state in close contact with the inner wall surface of the hose storage box 36 by its own restoring force (restoring force that the one wound by elasticity tries to return to the original straight state). It is stored. Here, “inner winding” refers to winding a wound object (for example, fire extinguishing hose 34) along the inner wall of a frame (for example, hose storage box 36).

The mobile package fire extinguisher having the above-described configuration is installed at a predetermined position of the building in a state where the lock mechanism is applied to the normal brake 18 where no fire has occurred.
When a fire occurs, the operator operates the brake lever 23 to release the lock mechanism of the brake 18, pushes the handle 21, moves the mobile package fire extinguisher 1 to the vicinity of the fire occurrence position, The lever 23 is operated to activate the lock mechanism of the brake 18.

Next, the operator opens the opening / closing door 32 and opens the start valve 37a. Then, the pressurized gas from the pressurized gas cylinder 37 is adjusted to a predetermined pressure by the pressure regulator 39 and introduced into each extinguishing agent filling container 33 through the pressurized gas introduction pipe 40. Then, the foam extinguishing agent in each extinguishing agent filling container 33 is introduced into the extinguishing hose 34 through the discharge collecting pipe 41.
Next, the operator holds the fire-extinguishing nozzle 35 in his / her hand, pulls out the fire-extinguishing hose 34 from the hose storage box 36, and approaches the fire occurrence place. At this time, the fire extinguishing hose 34 is housed in the hose storage box 36 by being wound inwardly from the back toward the opening side so that the fire extinguishing nozzle 35 is on the opening side. Since the notch 36a is formed in the lower part of the right side wall of the hose storage box 36, a fire extinguisher filling container 33 having a substantially circular horizontal cross section is provided on the right side of the hose storage box 36 so that a gap is formed on the right side of the notch 36a. It can be pulled out smoothly in both the front and left and right directions.

Then, the operator operates the lever 35a from a location a little away from the beginning, and discharges fire-extinguishing foam (low foaming) from the low firing water discharge portion 35b. When the fire is moderated to some extent, the fire is approached, and the lever 35a is operated to release the fire-extinguishing foam (medium foam) from the middle firing water discharge part 35c, thereby extinguishing the fire.
After the fire is extinguished, the operator closes the start valve 37 a and the lever 35 a and stores the fire hose 34 in the hose storage box 36. At this time, since the hose storage box 36 is smaller than the housing 4, the fire extinguishing hose 34 is easily opened in the hose storage box 36 so that the fire extinguishing nozzle 35 comes to the opening side (the base end side is the back). It can be accommodated so as to be wound inwardly counterclockwise toward the side. Then, the open / close door 32 is closed.

  When the fire hose 34 is pulled out for visual inspection or when the fire extinguisher filling container 33 and the pressurizing gas cylinder 37 housed in the housing 4 are replaced with new ones, the bottom mounting portion 12 is placed on the floor. Raise the back placing part 11 so as to be perpendicular to the floor. At this time, when the rear mounting portion 11 is raised, the rear wheel 16 floats from the floor, and the mobile package fire extinguisher 1 is rotatably supported only by the front wheel 15, so that the rear wheel 16 is easily raised. Further, since the tangent line of the front wheel 15 is included in the surface of the bottom surface mounting portion 12, the front wheel 15 moves when the bottom surface mounting portion 12 is placed on the floor and when the bottom surface mounting portion 12 is raised from the floor. Since the type package fire extinguisher 1 is rotatably supported, it is easy to raise and tilt.

Since the mobile package fire extinguisher 1 according to the present invention is mounted on a cart 3 with wheels, the mobile package fire extinguisher 1 disposed at a position away from the normal fire occurrence position is 1 A small number of people, such as two people, can move to a fire occurrence position and can be used for fire extinguishing, and many mobile package fire extinguishing apparatuses 1 can be used for fire extinguishing.
Moreover, since the fire extinguisher main body 2 is obliquely mounted on the carriage 3 and the carriage 3 is a four-wheel type, the center of gravity is located at a low position and between the front and rear wheels, and the stability during movement is excellent.
In addition, a brake 18 with a lock mechanism is attached to the front wheel 15 so that the lock mechanism can be operated so as not to move during normal or fire extinguishing, and the lock mechanism can be released when rushing to extinguish, so that the operation is simple.

  In addition, although the housing | casing 4 inclines about 45 degree | times and is mounted in the trolley | bogie 3, it does not necessarily restrict to 45 degree | times. However, when the casing 4 is placed on the carriage 3 in a substantially standing state at 80 degrees with respect to the wheels, the center of gravity does not decrease so much, but the center of gravity is located at a position close to the front wheels, which makes running stability difficult. . Moreover, when the casing 4 is placed on the carriage 3 in a state of being almost lying down at 20 degrees with respect to the wheels, the position of the handle 21 becomes too low to be pushed, and the fire extinguisher filling container 33 has many Extinguishing media will remain.
