DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a fire extinguisher installed on a passage wall of a building such as various facilities and buildings.

[0002]

2. Description of the Related Art Conventionally, there are various types of fire extinguisher installed in a building. However, the fire extinguishing apparatus can be installed in a relatively small place by simplifying the structure, and can quickly extinguish fire. In order to satisfy this demand, fire extinguisher with a circular cross section is wound in multiple rows and multiple layers from the outer side to the inner side in a hose storage box without using a hose reel. A structure was developed in which the base end of the outer fire hose was connected to a fire hydrant and a nozzle was attached to the tip of the innermost fire hose, so that the fire hose was fed out sequentially from the inner side to the outer layer during fire extinguishing. ing.

[0003]

However, fire hoses wound in multiple rows and multiple layers in the storage box from the outer periphery to the inner periphery are expanded in the outer diameter direction by the upper, lower, left and right wall surfaces of the storage box. Although the door is restricted from shaking and is prevented from being deformed rearward by the back plate of the storage box, a door which is openably and closably attached to the opening at the front opening side of the storage box. By holding on the inside of the
It is the current situation that is preventing shape loss. Therefore, when the door is opened in the event of a fire, the regulation is released and the fire hose is pushed forward, causing the fire to collapse and hinder smooth withdrawal, hindering fire fighting activities that require promptness. There was a problem.

Such a shape collapse can be eliminated by providing a front donut-shaped front wall plate on the front side of the wound fire hose, and the conventional fire extinguisher also employs this structure. However, in this case, when the hose is pulled out through the central hole of the donut-shaped front wall plate, not only the frictional force between the hose and the front wall plate becomes large, but also the hose is caught on the front wall plate, and rapid fire fighting cannot be performed. This causes a problem.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a fire extinguisher which can be smoothly pulled out of a storage box without collapse of a fire extinguishing hose even during use. To provide.

[0006]

In order to achieve the above object, a fire extinguisher according to the present invention comprises a multi-layer, multi-layer, multi-layered hose having a circular cross section from the outer side to the inner side in a storage box having an open front. In a fire extinguisher, the base end of the hose is connected to a hydrant valve and a nozzle is attached to the tip and the nozzle is pulled out to draw out the hose from the inner layer side to the outer layer side. A pair of regulating plates are provided on both sides of the opening of the storage box so as to be openable and closable, and the regulating plates are constantly urged toward the winding hose side by a spring force.

In the fire extinguisher having the above structure, the invention according to claim 2 is characterized in that the width of the pair of regulating plates is formed to be substantially equal to the layer thickness of the wound hose, and that the regulating plates face each other. A support fitting for detachably supporting the nozzle is mounted in an upper space between the inner ends, and the invention according to claim 3, wherein the opening end of the storage box on the front side of the regulating plate. And an opening / closing door for the opening.

[0008]

In normal operation, the winding hose stored in the storage box is prevented from expanding in the outer diameter direction by the upper, lower, left and right wall surfaces of the storage box, and maintains a wound state with a fixed diameter. In addition, the rearward deformation is restricted by the rear panel of the storage box. In addition, since the back surfaces of the left and right regulating plates are pressed against the front sides of the wound hose by the spring force, the wound hose is prevented from deforming forward.

In this state, there is no danger that the winding hose will be deformed at all even if the opening / closing door attached to the opening end of the storage box is opened in the event of a fire. As described above, the nozzle attached to the end of the hose is supported by the support fitting mounted in the upper space between the left and right regulating plates, so that the nozzle can be seen directly when opening the door. And the nozzle can be taken out quickly.

When the nozzle is taken out of the storage box, the wound hose is pulled out from its inner layer side. At this time, the right and left regulating plates are inclined forward against the spring force according to the pulling force and the pulling direction of the hose. The wound hose can be pulled out regularly and smoothly from the inner layer side to the outer layer while preventing the hose from deforming on its inner surface.

A hose receiving plate 3 curved in an upwardly arcuate shape with an appropriate degree of curvature protrudes forward, and is surrounded by the hose receiving plate 3, the lower surface plate 1c, and both side plates 1d and 1e. The hose 4 is stored in a wound state in the space. The hose 4 is a hose having a circular cross section made of rubber, synthetic resin, or the like having appropriate elasticity.

A fire hydrant valve 5 connected to and connected to a fire extinguishing water supply pipe (not shown) is mounted on an upper portion of one side of the storage box 1, and the base of the hose 4 is connected to the fire hydrant valve 5. At the same time, the outermost layer was formed by winding a plurality of rows of the hose 4 in the front-rear direction while contacting and receiving the hose 4 against the opposing surfaces of both side plates 1d and 1e of the storage box 1 and the lower surface plate 1c and the lower surface of the receiving plate 3. Thereafter, the next hose layer is wound in a plurality of rows in the front-rear direction on the inner surface of the outermost layer in the same manner, and is wound in a plurality of layers inward and stored in the storage box 1. I have. Therefore,
The wrapping hose 4 attempts to expand in the outer diameter direction due to its elastic force by using the side plates 1d and 1e, the lower plate 1c, and the receiving plate 3.
Regulated by

Further, the innermost hose 4 'is pulled out upward, and a nozzle 6 attached to the tip thereof is fixed to the upper center of the rear plate 1a of the storage box 1 near the upper portion of the hose receiving plate 3. It is detachably supported on a supporting bracket 7 formed of a bifurcated clip.

8 and 9 are hinges 10 on both sides of the opening of the storage box 1.
A pair of left and right vertically-regulated plates pivotally supported by the front-rear direction, the height of which is formed to reach the receiving plate 3 from the upper surface of the lower plate 1c of the storage box 1 and has a width. Are formed so as to have a width substantially equal to the width between the outermost hose portion and the innermost hose portion, and face the both sides of the front surface of the wound hose 4 respectively. Therefore, a space 11 is formed between the opposed inner ends of the restriction plates 8 and 9 so that the center hole of the wound hose 4 is exposed.

The hinges 10 are provided on at least two upper and lower portions of the regulating plates 8 and 9, with one half being on the regulating plates 8 and 9 side and the other half being on the inner side of both side plates 1d and 1e, respectively. The restricting plates 8 and 9 are attached so as to be able to rotate in the front-rear direction around a central axis 12 connecting the two halves by being fixed by screws.

To prevent the winding hose 4 from being deformed forward. Reference numeral 14 denotes an opening / closing door disposed at the front end of the opening 2 of the storage box 1 at the front side of the regulating plates 8 and 9, which normally closes the opening 2 of the storage box 1 entirely. .

The fire extinguisher constructed as described above is installed on the side wall of a passage in a building or the like, and when not in use, that is, in a normal state, the hose 4 is housed in the storage box 1 in the above-mentioned wound state and opened and closed. The door 14 is closed. In this state, the winding hose 4 attempts to expand in the direction of the outer diameter of the winding diameter by its elastic restoring force, so that the opposing surfaces of the side plates 1d and 1e of the storage box 1 and the lower surface plate 1c and the receiving plate 3 The hoses 4, which are blocked by the lower surface of the storage box 1, are pressed against each other by the pressure contact force and the elastic restoring force of each other so as to escape in the front-rear direction of the storage box 1.
The state in which the occurrence of deformation due to escape is suppressed by being regulated by the left and right regulating plates 8 and 9 which are in contact with the front side portions of the wound hose 4 and the back plate 1a of the storage box 1 due to the elasticity of the hose. Have maintained.

Next, when the open / close door 14 is opened in the event of an emergency due to a fire, the wound hose 4 is stored neatly in the storage box 1 as described above. Since the left and right regulating plates 8 and 9 prevent the forward delusion, they do not collapse. Further, the tip nozzle 6 of the hose 4 is provided with a support fitting 7 in an upper space between the left and right regulating plates 8 and 9.
When the opening / closing door 14 is opened, the nozzle 6 can be immediately taken out at a position where it is most easily confirmed.

When the nozzle 6 is taken out of the storage box 1, the wound hose 4 is moved from the inner layer side to the space between the left and right regulating plates 8 and 9.
At this time, the hose 4 comes into sliding contact with the inner surface (back surface) of one of the left and right regulating plates 8 and 9 each time the hose 4 is pulled out by one turn, and the regulating plates 8 and 9 are pressed against the spring force.
It is pulled out while pushing and spreading. That is, the right and left regulating plates 8 and 9 are opened in a forward inclined state against the spring force according to the pulling force and the pulling direction of the hose 4, and the inner surface of the winding hose 4 is restrained from deforming. Are sequentially and regularly fed out from the inner layer side to the outer layer. By opening the opening / closing cock 5a of the fire hydrant valve 5 before and after the nozzle 6 is taken out, fire-extinguishing water is injected into the winding hose 4 and injected from the nozzle 6.
