Description

The present invention relates to a fire hydrant device that houses a fire hose and a fire hydrant valve used for fire fighting activities in the event of a fire.

  Conventionally, as a fire hydrant device for extinguishing a fire generated in a building, for example, those shown in FIGS. 9 to 11 are known.

  FIG. 9 is a front view of a conventional fire hydrant device. The fire hydrant device 100 is provided with a fire hydrant door 104 that can be freely opened and closed via a hinge structure (not shown) on the front surface of a metal storage box 102. A notification panel 106 is provided, and an acoustic hole 112 is provided corresponding to the transmitter 108, the red indicator lamp 110, and the built-in alarm speaker.

  The red indicator lamp 110 is always turned on so that the installation location of the fire hydrant device 100 can be seen from a distance. In the event of a fire, when the switch inside the button is turned on by pressing the button provided in the center of the transmitter 108, a transmission signal is transmitted to the disaster prevention reception board in the monitoring room and a fire alarm is issued from the notification section of the disaster prevention reception board At the same time, the district acoustic signal is sent from the disaster prevention reception board to the district acoustic terminals installed at various locations, and an alarm sound is output at each predetermined location.

  FIG. 10 is an explanatory view showing the internal structure by removing the hydrant door 104 of the hydrant device 100 shown in FIG. 9. A hydrant valve 114 is arranged inside the storage box 102, and the hydrant valve 114 has a nozzle at the tip. A fire extinguishing hose 116 equipped with 118 is connected, and can be pulled out by being folded on the holder 120 in a folded state. FIG. 11 shows a state where the fire hydrant door 104 is opened, and the internal structure shown in FIG. 10 is omitted.

  Normally, the fire hydrant door 104 of the fire hydrant device 100 is closed as shown in FIG. 9, and is kept closed by an appropriate door lock mechanism or the like. When a fire occurs, the door lock mechanism is operated to release the door closed state, and the fire hydrant door 104 is opened as shown in FIG. 11. For example, one person pulls out the fire hose 116 while holding the nozzle 118 and fires. Two people or more perform fire extinguishing activities, such as going to the place of occurrence (fire extinguishing target), another person operating the transmitter 108 to report and opening the fire hydrant valve 114.

  This is to avoid the problem that if the hydrant valve 114 is opened while the hose is being pulled out, the hose may not be pulled out properly due to water pressure and its reaction, or a danger may arise, and the hydrant door should be opened during use. This is because it needs to be maintained by human hands.

Thus, a fire hydrant device that requires at least two-person operation is legally defined as a No. 1 fire hydrant, while a fire hydrant that allows one person operation is used to suppress reaction force due to water discharge and use a shape retaining hose. No.2 fire hydrant is legally stipulated.

Japanese Patent Laid-Open No. 9-38231

  By the way, as a statistical result in the fire fighting activity using such a fire hydrant device, it has been reported that the success example is only 10% with respect to the use example of the fire hydrant at the time of fire occurrence. This compares with the success rate of sprinkler fire extinguishing equipment being between 60% and 70%, resulting in a much lower percentage of successful fire hydrant cases.

  The reason why the success example of the fire hydrant device is low is that the fire hydrant device normally has the fire hydrant door 104 closed as shown in FIG. 9 so that the inside cannot be seen. The internal structure that houses the hose is not well known, and even if the fire hydrant door 104 is opened as shown in FIG. 11 in the event of a fire, depending on the angle, it is difficult to see the interior because it is blocked by the door. This is due to the difficulty. In addition, when a thing is placed in front of the fire hydrant door 104, it may be considered that the door cannot be opened quickly.

  Also, opening the fire hydrant door on a daily basis and checking the interior is one of the factors that are difficult to handle because it strongly gives the impression of using a metal fire hydrant door and closing it firmly.

  On the other hand, the conventional fire hydrant device is provided with a metal fire hydrant door in the metal storage box in order to realize a fireproof structure, and the opening / closing structure and the lock structure are not only complicated, but also have a strength exceeding a predetermined level. There is also a problem that the cost is expensive.

An object of the present invention is to provide a fire hydrant device that solves the above-described problems, makes the open structure of the fire hydrant device simple and easy to handle, and reduces the cost.

The present invention is a fire hydrant device in which a fire hydrant valve and a fire hose are housed inside a storage box opened on the front surface.
Storage box, arranged freely rectangular sheet member opened and closed by the full Asuna in front of the opening,
The fasteners are separated into two sides at the opening when opened,
The sheet member has a first side fixed to one edge of the opening and cannot be opened, and one of the fasteners is provided on the second side opposite to the first side to be detachable from the other side of the fastener, The third side and the fourth side are made to coincide with the other edge of the opening in an unconstrained state .

Here, the storage box is provided with the other side of the fastener at the upper edge of the opening, and the sheet member fixes the first side to the lower edge of the opening and the second side to the upper edge of the opening by the fastener. When it is detachably mounted and the fastener is separated , the sheet member opens downward to open the opening to the front. Alternatively, the storage box is provided with the other of the fasteners on one of the side edges of the opening, and the sheet member fixes the first side to the other of the side edges of the opening, and the second side with the fastener is on the side of the opening. When it is detachably attached to one of the edges and the fastener is separated, the sheet member opens to the other side of the side edge of the opening to open the opening to the front. Furthermore, the sheet members are first and second sheet members arranged on the left and right sides, and the first side of each sheet member is fixed to each of the side edges of the opening, and the second sides of each sheet member are fastened to each other. When the fasteners are separated, the sheet members may be opened to the left and right to open the opening to the front .

Sheet member, so as to comprise a freely bellows structure folding also rather good, preferably formed of a material non-flammable or flame retardant.

  According to the present invention, since the opening of the storage box containing the fire hydrant valve and the fire hose is covered with a nonflammable or flame retardant sheet member that can be opened and closed by a fastener, compared to a conventional metal fire hydrant door, The structure is greatly simplified and the weight is reduced, and the cost can be reduced.

Also, since the open space can be reduced by opening the seat member by operating the fastener, it does not pop out to the front of the device like a fire hydrant door, and the internal structure containing the fire hydrant valve and fire hose can be easily confirmed from the outside As a result, handling becomes easy, and it can be expected that the ratio of successful examples by the fire hydrant device is increased.

  FIG. 1 is an explanatory view illustrating an embodiment of a fire hydrant device according to the present invention. In FIG. 1, a fire hydrant apparatus 10 according to the present embodiment includes a metal storage box 12 in which a fire hydrant valve and a fire hose are housed, as in the conventional example of FIG. An incombustible or flame retardant fiber sheet 24 that can be opened and closed by a fastener 28 is disposed. The fiber sheet 24 has a lower end fixed to the lower edge of the opening 14, and the side edge is not constrained by the front side frame of the storage box 12 (the front side edge of the opening 14) and is in a free state. The front side of the fire hydrant device 10 is referred to as “front”.

The fastener 28 has a known fastener structure. The tape 28c and 28d are provided with elements 28a and 28b that can be engaged with each other, and the tape 28c on which the element 28a is arranged is placed on the bottom edge of the storage box. Mounted on the upper edge of the non-combustible or flame-retardant fiber sheet 24 fixed to the side front frame (the front lower edge of the opening 14), and the tape 28d on which the element 28b is disposed is attached to the upper front edge of the opening 14 of the storage box 12. By attaching the slider 30 provided with the handle 32 to the lower edge of the non-flammable or flame-retardant fixing sheet 26 fixed to the right end of the elements 28a and 28b and moving to the left end as shown, the fastener The 28 elements 28 a and 28 b are meshed with each other to close the opening 14 of the fiber sheet 24.

  In addition, a notification panel 16 is provided in the upper portion of the storage box 12, and a transmitter 18, a red indicator lamp 20, and an acoustic hole 22 such as a built-in speaker are provided therein.

  FIG. 2 is an explanatory view showing a state in which the opening is opened in the embodiment of FIG. In the event of a fire, the fastener 28 is opened while releasing the meshing of the elements 28a and 28b by moving the slider 30 to the right with the handle 32 of the fastener 28 closed as shown in FIG.

  When the fastener 28 is opened and the slider 30 is moved to the right end, the lower element 28a is detached from the slider 30. As a result, the fiber sheet 24 is brought into a free state, and is lowered downward as shown in FIG. The opening 14 of the box 12 is opened to the front and the inside is accessible. A structure for preventing the slider 30 from falling off is provided at the right end of the element 28b. Even if the slider 30 is moved to the right end of the fastener 28, the slider 30 does not drop off from the element 28b.

  Although not shown in the inside of the opening 14 opened to the front surface, a fire hydrant valve and a fire hose are housed in the same manner as the conventional example of FIG. The other operator pushes the button of the transmitter 18 to open the fire hydrant valve, and in this case, two people perform fire fighting activities.

  When the fire fighting is over, the fire hydrant valve is closed, the fire hose is drained and dried, and then stored using the holder in the storage box 12, and when this is done, the fiber sheet 24 is pulled up and the element The right end of 28 a is fitted into the slider 30, and the slider 30 is moved to the left end by the puller 32 to close the fastener 28 and close the opening 14 with the fiber sheet 24 as shown in FIG.
