Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a fire hydrant device that is mainly installed on the wall of a building and used for firefighting.

(Prior Art) Generally, hose reel type fire hydrant devices are widely used as fire hydrant devices installed on the walls of buildings.

That is, the fire hydrant device has a hose reel wound with a hose rotatably disposed in a fire hydrant box buried in a wall, etc., and the base end of the hose is connected to a fire hydrant valve provided in the fire hydrant box. When the hose is pulled in the event of a fire or the like, the hose is quickly and smoothly stretched by the rotation of the hose reel. Further, as the hose, a cloth hose, a rubber hose, or a shape-retaining hose is usually used.

However, in fire hydrant devices that use fabric hoses, the fabric hose does not have shape retention properties, so the fabric hose has a flat cross-sectional shape when no water is flowing through it, and when it is wound around a hose reel, it does not allow water to flow through it. I couldn't do it. As a result, water supply could only be started after the entire hose had been stretched from the hose reel, and there was a problem in that prompt fire extinguishing work could not be carried out.

On the other hand, fire hydrant devices using rubber hoses and shape-retaining hoses do not suffer from the above-mentioned problems because they have shape-retaining properties and maintain an annular cross-sectional shape that allows water to flow even when wound around a hose reel. , can carry out rapid fire extinguishing operations.

However, since rubber hoses and shape-retaining hoses have shape-retaining properties, it is necessary to use large and thick hose reels. As a result, the thickness of the fire hydrant box inevitably becomes thicker, which creates the problem that if the wall of the building is thin, the fire hydrant box cannot be buried in the wall.
It was also difficult to handle.

Furthermore, rubber hoses and shape-retaining hoses are more expensive and less economical than cloth hoses. Furthermore, they are considerably heavier than cloth hoses and have a problem of being inferior in handling.

(Problems to be solved by the invention) The present invention was devised to solve the above-mentioned problems, and its purpose is to quickly discharge water, reduce the thickness of the fire hydrant box, and To provide a fire hydrant device which is excellent in economy and ease of handling.

(Means for Solving the Problems) The fire hydrant device of the present invention is housed in a fire hydrant box parallel to the rear wall of the fire hydrant box, is provided so as to be rotatable in the front direction, and extends in parallel. A pair of upper and lower hose holders are energized to reduce the distance between the upper and lower hose holding surfaces, and each of the hose holders is wound in a single layer in a V-shape along the longitudinal direction thereof. It is distinctive in that it is equipped with a cloth hose.

(Function) When not in use, a pair of upper and lower hose holders are stored in the fire hydrant box parallel to the rear wall thereof, and a cloth hose is wound around each hose holder in a single layer in a figure-eight shape. has been done.

In the event of a fire, etc., rotate the hose holder toward you, open the fire hydrant valve to allow water to flow through the hose, and hold the nozzle and the tip of the hose to pull them in the longitudinal direction of the hose holder. , stretch the hose.

In addition, when water is passed through a cloth hose, the hose expands and at the same time, the space between the hose holders is reduced by the expansion force of the hose, so the hose remains stable and secure even when wound around the hose holder. It swells and water can be pumped. As a result, water can be sprayed quickly. Further, since the hose is pulled in the longitudinal direction of the hose holder, it can be easily removed from the hose holder. Furthermore, since the hose is wound in a V-shape around the upper and lower hose holders, it can be stretched well without twisting.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

1 to 5 show a fire hydrant device according to an embodiment of the present invention, in which 1 is a fire hydrant box, 2 is a fire hydrant valve,
3 is a hose holder, and 4 is a cloth hose.

The fire hydrant box 1 is composed of a box-shaped main body 5 with an open front, and a front door 6 etc. that is rotatably attached to the front of the main body 5 to open and close the opening.
It is installed in a recess formed in the wall of a building. Note that the front door 6 of the fire hydrant box 1 may have a double-door structure.

The fire hydrant valve 2 is fixed to the side wall of the main body 5 of the fire hydrant box 1, and its inlet port is connected to a high-pressure water source via piping or the like.

The hose holders 3 are provided at upper and lower positions within the fire hydrant box 1, extend in parallel, and are held under pressure so that the vertical distance between the hose holding surfaces 3a can be reduced.

That is, the hose holding body 3 has a gutter shape with an arcuate cross section, and its outer peripheral surface serves as a hose holding surface 3a.

The hose holder 3 is supported by a support mechanism 7, which will be described later, so as to be substantially parallel to the upper and lower positions in the fire hydrant box 1 and to rotate synchronously in the front direction. It is energized so that the interval can be reduced.

The support mechanism 7 includes a mounting base 8 fixed to the rear wall of the main body 5 of the fire hydrant box 1, a U-shaped support plate 9 pivotably supported on the mounting base 8, and a vertical position of the support plate 9. substantially parallel upper support rods 10 and lower support rods 11, each of which is cantilever-supported, and the distance between the free ends is set to be slightly smaller than the distance between the base ends;
It is composed of a plurality of compression springs 12 and the like attached at regular intervals to the upper surface side of the upper support rod 10 and the lower surface side of the lower support rod 11. ,
One hose holder 3 is mounted parallel to the upper support rod 10 and the hose holding surface 3a faces upward, and the compression spring 1 on the lower support rod 11 side
The other hose holder 3 is attached to the lower end of the hose holder 2 so as to be parallel to the lower support rod 11 and with the hose holding surface 3a facing downward.

Therefore, each hose holder 3 is connected to the upper and lower support rods 1.
0 and 11 can be stored in the fire hydrant box 1 in parallel with the rear wall by rotating them toward the rear wall of the main body 5, and by rotating the upper and lower support rods 10 and 11 toward the front, the fire hydrant box can be stored. 1. Can be taken out. Moreover, each hose holder 3 has a compression spring 1
The biasing force No. 2 maintains biasing so that the vertical distance between the hose holding surface 3a and the hose holding surface 3a can be reduced.

Note that the support mechanism 7 is not limited to that of the above embodiment, and can support the pair of upper and lower hose holders 3 so as to be rotatable in the front direction, and can reduce the vertical distance between the hose holding surfaces 3a. It may be of any structure and type as long as it can maintain the force.

On the other hand, as shown in FIGS. 4 and 5, the hoses 4 are formed in a V-shape on the hose holding surface 3a of each hose holder 3 from the base end (support plate 9 side) to the distal end. It is wound in a single layer, and its base end is connected to the fire hydrant valve 2, and its tip end is connected to a nozzle 13. Furthermore, hose 4
Conventionally known fabrics are used.

When not in use, the pair of upper and lower hose holders 3 are stored in the fire hydrant box 1 parallel to the rear wall thereof, and each hose holder 3 has a hose 4 attached thereto.
It has a V-shape and is wound in a single layer.

When a fire or the like occurs, the front door 6 of the fire hydrant box 1 is opened, the hose holder 3 is rotated toward the front, and it is taken out of the fire hydrant box 1. Next, open the fire hydrant valve 2 to allow water to flow through the hose 4, and hold the tips of the nozzle 13 and the hose 4 and move them to the hose holder 3.
The hose 4 is stretched by pulling it in the longitudinal direction.

When water is passed through the hose 4, the hose 4 expands, and at the same time, the expansion force of the hose 4 moves the upper and lower hose holders 3 toward each other against the biasing force of the compression spring 12, and the hose 4 expands. The vertical distance between the holding surfaces 3a is reduced. As a result, even when the hose 4 is wound around the hose holder 3, the hose 4 can inflate well and reliably to supply water, and water can be discharged quickly. Furthermore, since the hose 4 is pulled in the longitudinal direction of the hose holder 3, it can be easily pulled off from the hose holder 3. In particular, since each hose holder 3 is arranged in an inclined state so that the distance between the tips is small, the hose 4 can be pulled out even more easily. Furthermore, hose 4
Since it is wound around the hose holder 3 in a V-shape, it can be stretched well without twisting.

On the other hand, after use, the fire hydrant valve 2 is closed, the dried hose 4 is wound around the hose holder 3 in a single layer in a V-shape, and these are stored in the fire hydrant box 1.

In the above embodiment, the upper and lower hose holders 3 can be moved toward each other, but in other embodiments, only one of the upper and lower hose holders 3 can be moved up and down. The other hose holder 3 may be attached in the fire hydrant box 1 so as to be movable in the direction, and the other hose holder 3 can be rotated in the front direction but not movable in the vertical direction.

Further, in the above embodiment, the hose holder 3 has a gutter shape with an arcuate cross section, but the hose holder 3 is not limited to that of the above embodiment, and has a hose holding surface extending in the longitudinal direction. 3a, it may have any shape and structure.

Furthermore, in the above embodiment, the hose holder 3
The distance between the hose holders 3 is reduced by moving the The vertical distance between the hose holding surfaces 3a may be reduced.

In addition, in the above embodiment, each hose holder 3 was attached to the main body 5 side of the fire hydrant box 1, but in other embodiments, the hose holder 3 was attached to the back side of the front door 6. They may be installed parallel to this and at a constant interval.

In other words, the hose holder 3 is stored in the fire hydrant box 1 parallel to the rear wall thereof, and
It is sufficient that it is rotatably provided in the front direction, extends in parallel, and is held under pressure so that the vertical distance between the hose holding surfaces 3a can be reduced.

(Effect of the invention) As mentioned above, the fire hydrant device of the invention has a pair of upper and lower hose holders which are held under pressure so that the distance between the upper and lower parts can be reduced, and a cloth hose is arranged in a V-shape along the longitudinal direction of the pair of hose holders. Moreover, since the hose is wound in a single layer, when water is passed through the hose, the hose expands and at the same time, the vertical distance between the hose holders is reduced due to the expansion force of the hose. As a result, the cloth hose can inflate well and reliably even when wound around the hose holder, and can supply water. As a result, water can be sprayed quickly.

In addition, since the elongated hose holder is stored in the fire hydrant box parallel to its rear wall,
The thickness of the fire hydrant box can be made thinner than the conventional fire hydrant box that stores the hose reel.
As a result, the fire hydrant box can always be properly and reliably installed on the wall surface, etc., regardless of the thickness of the wall of the building, and the fire hydrant box is also extremely easy to handle.

Furthermore, since the fire hydrant device uses a cloth hose, it is cheaper and lighter than those using rubber hoses and shape-retaining hoses.
It is economical and easy to handle.

In addition, since the hose is wound around the upper and lower hose holders in a V-shape, even if the hose is pulled in the longitudinal direction of the hose holder and removed from the hose holder, the hose will not twist. Good stretching.
