[Action]

 After hugging the elastic guide rods protruding in the vertical direction inwardly on the side wall of the hose storage box of the hose storage box from one end of the shape-retaining hose in layers from top to bottom, The nozzle connected to the other end is exposed and placed inside the circular frame. When a nozzle is grasped in the event of a fire, the shape-retaining hose is pulled out from the lower elastic guide rod to the upper guide rod one by one, so the nozzle is pulled close to the fire site, the fire hydrant is opened, and water is sprayed from the nozzle. To do. After extinguishing the fire, close the fire hydrant, remove the shape retaining hose from the fire hydrant, dry it, and then connect one end of the shape retaining hose to the fire hydrant again and place the shape retaining hose on the elastic guide rod and return it to the original position. Return and store in the hose storage box. By pulling the string, the fire hydrant lever is rotated to open the fire hydrant, and the ball that is locked to the door is disengaged from the door and is opened by opening the fire hydrant. Take it out from the hole in the circular frame.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. 1, FIG. 2, FIG. 3, FIG. 4, and FIG. 5, 1 represents the ceiling of the building. A circular frame 3 provided with a circular hole 2 is arranged along the ceiling inside the circular hole 1a formed in the Amai. Further, a cover plate for blindfolding the circular hole 1a can be attached to the circular frame 3. A hose storage box 4 is placed and arranged on the upper surface of the ceiling 1 outside the circular frame 3. Inside the side walls 5, 5, 5, 5 at the four corners of this hose storage box 4, a plurality of elastic guide rods 6, 6, 6, 6 are provided in the upper part in a horizontal and axial direction. The length is gradually increased toward the lower part, and the tip part is centripetally projected toward the center part.

Reference numeral 7 denotes a shape-retaining hose, one end of which is connected from the outside to a fire hydrant 9 of a water supply pipe 8 arranged inside the hose storage box 4. A fire extinguishing nozzle 10 is attached to the other end of the shape-retaining hose 7. As can be seen from FIGS. 1 and 2, from the base of the shape-retaining hose 7 connected to the fire hydrant 9, this is placed on the upper guide rods 6, 6, 6, 6 and the side walls 5, 5, 5, 5 In a circle along the line. After the winding is completed, the elastic guide rods 6, 6, 6, 6 in the next lower stage are placed and the winding is performed in the same manner as described above. By repeating the above-mentioned winding operation, the shape-retaining hose 7 held by the elasticity of the guide bar is pulled out between the lowermost elastic guide bar 6 and the upper surface of the hose storage box 4, and is attached to the tip of the shape-retaining hose 7. Place the attached nozzle 10 on the upper surface of the bottom plate 4a of the hose storage box 4. Since the shape-retaining hose 7 is sandwiched and elastically held between the elastic guide rods 6 and 6, the shape-retaining hose 7 that has been caught and held does not collapse unintentionally. 6, 7, 8, and 9 show another embodiment, in which a two-way ball valve is used for the fire hydrant 9. FIG. 6 shows a state in which the lever is in contact with the stopper A and the valve is closed. A string 22 is connected to the lever 9a, a ball 21 having a hole 20 at the center is communicated with the string 22, and an elastic stopper 23 is connected to the string at the lower part of the string 22. Further, the pull tab knob 24 is fixed. a is a door, and in the door a, a string 22 enters a notch 25 of the door, and the notch 25 is supported by a ball 21 communicated with the string 22, and the ball 21 is supported by a stopper 23. ing. The string is fixed to the lever 9a of the two-way ball valve. Since the force of turning the lever 9a of the two-way ball valve is larger than the weight of the door a on one side and the door b on the other side, the state of FIG. 6 is maintained and the two-way ball valve is kept closed. To do. In an emergency, when the pull knob 24 is pulled downward, the lever 9a of the two-way ball valve rotates 90 °, hits the door b on the other side, and the two-way valve opens. Further, the stopper 23 and the ball 21 connected to the string 22 also move downward. When the ball 21 moves downward, the door a on one side is opened in the direction of the arrow in FIG. 8 due to the notch 25, and the doors b on the other side are also sequentially opened.

When the fire extinguishing work is completed and the two-way ball valve is returned to its original state, the two-way ball valve is turned 90 ° as shown in FIG. , The door b is closed, and the door a is closed. Next, by holding the string 22, the ball 21 is moved above the stopper 23. As described above, the single stopper 22 and the string 22 having the ball 21 can open the fire hydrant valve and simultaneously open the doors a and b on both sides.

[0009]

As described above, according to the present invention, a plurality of elastic guide rods are projectingly provided on the side wall of the cubic hose storage box used on the ceiling, and the tips thereof are centripetally arranged. In particular, the shape-retaining hose can be housed in the space between the upper and lower parts of these guide bars. When using the nozzle in an emergency, the nozzle can be pulled out smoothly from the circular hole in the circular frame, and the shape-retaining hose can be easily retained without losing its shape without the reel, and the fire-hose can be used. It can be stored again quickly after use, and requires a small installation area, which is effective for ceilings.
