Description

The present invention relates to a fire hydrant device provided with a hose accommodating portion for accommodating a fire extinguishing hose by winding it inward in a housing.

Inside the housing of the fire hydrant device, a hose accommodating portion for accommodating a hose for extinguishing a fire (hereinafter, simply referred to as “hose”) is provided, and the hose accommodated in the hose accommodating portion has a strong hollow circular cross section. It is a shape-retaining hose with shape-retaining properties, and is housed by being wound inward in the hose accommodating part.

As shown in FIG. 10, the above-mentioned inward winding is a winding method in which the hose 53 is wound by pressing the hose 53 against the frame inside the frame called the hose accommodating portion 51, and is described in the hose 53. It is wound in the order of numbers. That is, as shown in FIG. 10, the hose 53 winds the outermost circumference in order from the rear toward the front (circled numbers 1 to 4), and when it comes to the frontmost, then one step inward from the outermost circumference. Enter and wind from the front to the back (circled numbers 5 to 10). Further, when it reaches the rearmost side, it goes further inward and winds from the rear side toward the front (circled numbers 11 to 16), and so on.

Further, the front panel of the fire hydrant device is provided with a front opening, and a front door is provided so that the front opening can be opened and closed, and the hose is pulled out from the front opening with the front door open.
When the inwardly wound hose is pulled out from the front opening, the hose rises from the lower side toward the front opening and then is pulled out to the outside. At this time, the hose bends significantly below the front opening, making it impossible to smoothly pull out the hose, and there is a possibility that the water discharge pressure may be adversely affected. It is proposed to provide an overhanging hose guide portion formed so as to project the lower side of the take-out port forward. "

As shown in FIG. 1, the fire hydrant device 1 according to the present embodiment is formed on a hose accommodating portion 7 for accommodating a fire extinguishing hose 5 inwardly wound in a housing 3 and a front panel 9 of the housing 3. The front opening 9a has a forward tilting door 11 as a front door that can be opened and closed, and the hose 5 is pulled out from the front opening 9a with the forward tilting door 11 open. A hose guide 13 is provided on the portion 9a so as to be swingable in the front-rear direction.
In the following, after the overall configuration of the fire hydrant device 1 is outlined, the hose guide 13 which is a feature of the present invention will be described in detail.

<Overall configuration of fire hydrant device>
As shown in FIGS. 1 and 2, the fire hydrant device 1 has a box-shaped housing 3, a front panel 9 having a front opening 9a provided on the front surface of the housing 3, and a front opening 9a of the front panel 9. It is equipped with a forward tilting door 11 that can be opened and closed.
In the present specification, "front" as a term indicating a position in the fire hydrant device 1 means the front panel 9 side in FIGS. 1 to 9, and "rear" means the back panel 35 side.
Hereinafter, each configuration will be described in detail.

<Case>
As shown in FIGS. 1 and 2, the housing 3 has a rectangular box shape, and a hose accommodating portion 7 for accommodating a hose 5 wound inward is provided in the housing 3, and a hose is provided. A piping system 15 having a maintenance valve or the like is provided on the right side of the accommodating portion 7. The tip side of the piping system 15 is located on the side of the hose accommodating portion 7, the proximal end side of the hose 5 is connected to the distal end, and the proximal end side of the piping system 15 is connected to a water supply source (not shown). The outside of the body 3 is provided with a fire hydrant valve and an automatic pressure regulating valve (not shown).

<Front panel>
The front panel 9 is provided on the front surface of the housing 3, and a portion located in front of the central opening 17 in the hose accommodating portion 7 is opened, and the front tilting door 11 can open and close the front opening 9a. It is attached, and a fire extinguisher door 19 is provided on the left side of the front panel 9 so as to be openable and closable.

<Forward tilting door>
The forward tilting door 11 has a horizontally long rectangular shape composed of a plate-shaped metal plate, and is attached to the front opening 9a of the front panel 9 so as to be openable and closable as described above.
The forward tilting door 11 is provided with rotating shafts 21 at both ends of the lower side, and the front opening 9a can be opened by approximately 180 ° from the closed state as shown in FIG.
On the inner surface side of the forward tilting door 11, the nozzle holding portion 25 for detachably holding the fire extinguishing nozzle 23 and the fire hydrant valve provided in the fire extinguishing water supply pipeline for supplying fire extinguishing water to the hose 5 are opened and closed. A lever 27 is provided.
A transparent acrylic plate is installed at a portion of the forward tilting door 11 corresponding to the nozzle holding portion 25, and the fire extinguishing nozzle 23 detachably fixed on the inner surface side of the forward tilting door 11 can be seen.

<Hose housing>
As shown in FIGS. 1 to 7, the hose accommodating portion 7 connects a pair of vertical side portions 29 erected across the central opening 17 and upper ends and lower ends of the pair of vertical side portions 29. A pair of horizontal side portions 31 are provided as described above, and a pair of substantially L-shaped strip portions 33 in a plan view are provided on the pair of vertical side portions 29 in this frame body.
The hose 5 is internally wound in the space between the pair of strips 33 and the back panel 35 (see FIG. 7).

<Hose guide>
The hose guide 13 is arranged in the front opening 9a and is swingably attached in the front-rear direction to support and guide the hose 5 to be pulled out.
Specifically, as shown in FIG. 3, the chain 39 is inserted into a metal pipe 37 curved so as to be convex downward, and both ends of the chain 39 are attached to and detached from the locking portion 41 provided on the vertical side portion 29. It is configured to be mounted as possible.
By locking both ends of the chain 39 to the locking portion 41, the metal pipe 37 into which the chain 39 is inserted swings back and forth.

As a method of detachably attaching the end portion of the chain 39, a component that can open and close the ring, such as a carabiner, may be attached to the end portion of the chain 39 so that the opening and closing function of the carabiner can be used.
As shown in FIG. 3, since the chain 39 on the right side in the figure has a margin in length, the amount of hanging of the chain 39 can be changed by changing the position where the carabiner is attached. Thereby, the height position of the metal pipe 37 can be changed. The relationship between the height position of the metal pipe 37 and the function as the hose guide 13 will be described later.

The fire hydrant device 1 of the present embodiment configured as described above, and particularly the function of the hose guide 13, will be described in detail below.
When the hose 5 is pulled out to the front, the hose 5 is supported by the hose guide 13 as shown in FIG. 3, but at this time, as shown in FIG. 4, the hose guide 13 swings forward, so that the hose 5 Is supported by the hose guide 13 at a position protruding forward from the front opening 9a. That is, when the hose 5 is pulled out, the hose guide 13 swings, so that the hose support position of the hose guide 13 can be automatically extended. As a result, as shown in FIG. 4, the radius of curvature of the bending of the hose 5 under the front opening 9a can be increased, the hose can be smoothly pulled out, and the water discharge pressure is not adversely affected. ..

In this regard, in Patent Document 1, since the overhanging hose guide portion is configured by a fixed pipe in order to obtain this effect, a space is required in the housing by the amount of the overhanging, and the thinning of the housing is hindered. .. On the other hand, in the present embodiment, the hose guide 13 automatically protrudes by the operation of pulling out the hose when the hose is pulled out, and when the hose 5 is not pulled out, the hose guide 13 is accommodated in the housing 3. Along with the thinning of the hose, the hose can be pulled out smoothly.

Further, when the hose 5 is pulled out in the lateral direction, for example, to the left side in the figure as shown in FIG. 5, or to the right side in the figure as shown in FIG. 6, the hose guide 13 is forward as in the case of pulling out to the front. Since it swings to the above, the same effect as the above-mentioned effect can be obtained. Further, when the hose 5 is pulled out in the lateral direction, the metal pipe 37 constituting the hose guide 13 is curved so as to be convex downward, so that the support positions of the pulled out hose 5 are shown in FIGS. 5 and 6. As described above, the position is closer to the center without moving to the vicinity of both ends of the front opening 9a.
Therefore, as shown in FIG. 7 (a), the radius of curvature of the bending of the hose 5 is increased even when the hose guide 13 is pulled out in the same direction as compared with the case where the hose guide 13 is not provided as shown in FIG. 7 (b). It is possible to facilitate the hose withdrawal.

The hose guide 13 shown in the above embodiment is one aspect of the present invention in which a rod-shaped body curved or bent so as to be convex downward is suspended and supported. The example of the body is not limited to the metal pipe 37, and may be a resin pipe. Further, the rod-shaped body may be a solid body rather than a hollow body such as a pipe. In this case, both ends of the rod-shaped body may be suspended and supported by a chain or the like.
Further, although the above embodiment is an example in which the rod-shaped body is curved, the rod-shaped body may be bent. In this case, for example, like an inverted trapezoid, the upper bottom may be the base and the upper end of the hypotenuse may be swayably suspended.

Further, as another aspect of the hose guide 13, as shown in FIG. 8, the hose guide 13 may be composed of only the chain 39 without providing the metal pipe 37. In this case, the hose guide 13 of the present invention is one aspect of the hose guide 13 "consisting of a deformable linear member that hangs downward so as to be convex downward".
In the case of such a linear member, when the hose 5 is pulled out in the lateral direction, the chain 39 swings forward and bends and deforms to the side of the hose 5, as shown in the chain 39 shown in FIG. Since the guide is guided while restricting the movement, the same effect as that of the above embodiment can be obtained.
Examples of the linear member other than the chain 39 include a wire rope having a certain thickness (for example, about 1 to 4 cm in diameter).

In the above embodiment, the metal pipe 37 is curved so as to be convex downward, so that the hose 5 moves to the end of the front opening 9a when the hose 5 is pulled out laterally. It was restricted to increase the radius of curvature of the bending of the hose 5.
As described above, as a means for increasing the radius of curvature of the bending of the hose 5 when the hose 5 is pulled out in the lateral direction, for example, as shown in FIG. 9, the ring member 43 made of a ring through which the hose 5 can be inserted is formed. Both sides may be suspended and supported by a string-shaped member such as a wire rope 45. Thereby, the hose 5 can be restricted from moving to the end of the front opening 9a. The ring member 43 is an aspect of the "movement restricting unit that regulates the movement of the hose to both ends when the hose is pulled out" of the present invention.

In the above description, the functions of the hose guide 13 are mainly to facilitate the hose withdrawal and to make the housing 3 thinner. However, in the hose guide 13 of the present invention, the hose 5 accommodates the hose when the hose is withdrawn. Since there is a function to prevent a phenomenon in which the hose is unwound by itself (or in a chain) from the part 7, that is, a so-called hose loosening phenomenon, this point will be described below.

First, since the hose guide 13 of the present invention regulates the range of movement of the hose 5 to the left and right, the amount of left and right movement is smaller than that of the hose 5 moving to the left and right ends of the front opening 9a at the time of withdrawal. , The influence of the pulling force on the hose wound inward in the housing 3 can be mitigated, and thereby the hose loosening phenomenon can be prevented.
Further, since the position of the hose 5 supported by the hose guide 13 is higher than the position of the lower side of the front opening 9a, the amount of the hose 5 remaining below the position where the pulled out hose 5 is supported is large. Therefore, when the hose is filled with water, the force with which the hose 5 is pressed downward becomes stronger, which can prevent the hose from loosening.
Further, since the hose guide 13 is provided on the left and right sides of the front opening 9a, the hose guide 13 on the upper side of the winding of the hose 5 wound inward comes into contact with and supports the front opening 9a when the hose guide 13 falls down on the front opening 9a. By doing so, it is possible to prevent the hose from coming loose.

From the viewpoint of preventing the hose from coming loose, it is preferable that the height position of the hose guide 13 at the front opening 9a can be adjusted. This is because it is not preferable that the position of the hose guide 13 is too high from the viewpoint of preventing the hose 5 from collapsing, and the position of the hose guide 13 from the viewpoint of increasing the amount of hose below the support position of the hose 5. This is because it is preferable to increase the value, and it is preferable that the position can be adjusted to achieve both of these.

When the end portion of the hose guide 13 is made detachable, the inward winding work can be smoothly performed by removing one end of the hose guide 13 when winding the hose 5 inward.
However, it is conceivable to forget to lock one end of the hose guide 13 to the locking portion 41 when the inward winding work is completed.
In order to prevent this, a temporary holding portion for temporarily holding one end of the hose guide 13 is provided in the housing 3 or inside the housing 3, and the back side of the forward tilting door 11 (when the forward tilting door 11 is opened). The forward tilting door 11 interferes with the hose guide 13 so that it cannot be closed when one end of the hose guide 13 is held in the temporary holding portion. Is preferably held in the temporary holding portion, and when the inward winding work is completed, one end of the hose guide 13 is replaced from the temporary holding portion to the locking portion 41.

In the above embodiment, the hose guide 13 is attached to the locking portion 41 provided on the vertical side portion 29 as the attachment position at both ends of the hose guide 13, and the hose guide 13 crosses the front opening 9a to the left and right. However, the hose guide of the present invention may be arranged in the front opening 9a and mounted so as to be swingable in the front-rear direction to support the hose to be pulled out, and the mounting positions at both ends are particularly high. Not limited.
Therefore, for example, both ends of the hose guide may be attached near both ends of the upper portion (upper side portion) of the front opening so that the hose guide hangs downward, or one end of the hose guide may be attached to the vertical side portion of the front opening 9a. The other end may be attached to the upper part (upper side portion) of the front opening (near the upper end portion of the vertical side portion facing the vertical side portion).
Further, when the ring member 43 shown in FIG. 9 is used, the attachment position of the end portion of the wire rope 45 that suspends and supports the ring member 43 can be selected in a wider range.
