  As shown in FIGS. 7 to 9, a hose storage portion 9 for storing the hose 8 wound in the inner winding is provided in the housing 3. In the housing 3, a piping system 11 having a fire hydrant valve and an automatic pressure regulating valve is provided on the right side of the hose storage portion 9. The piping system 11 has a distal end side connected to the proximal end side of the hose 8 and a proximal end side connected to a water supply source (not shown).

The hose storage portion 9 includes two rod-like bodies 13 extending from the inner wall upper surface of the main body 3 to the inner wall lower surface, and two strips 15 bent in a substantially L shape extending from the rod-like body 13 to the inner wall rear surface of the main body 3. It is prepared for. Then, the hose 8 is drawn from between the two rod-like bodies 13.
The front panel 5 is provided on the front surface of the housing 3, and an opening 5a is formed in a front part where the hose 8 is pulled out, and a descending door 7 is attached so that the opening 5a can be closed.

A fire extinguishing nozzle 16 is attached to the tip of the hose 8, and in the stowed state, as shown in FIGS. 7 and 8, the fire extinguishing nozzle 16 is pointed upward by a nozzle catch 103 fixed inside the housing 3. Removably held.
The lowering door 7 moves downward along the front panel 5 as shown in FIG. 10B, and is held by the nozzle catch 103 as shown in FIG. 10A when the lowering door 7 is opened. The fire extinguishing nozzle 16 is visible in a removable state.
In addition, a maintenance valve 19 is provided immediately above the fire-extinguishing nozzle 16 held by the nozzle catch 103 so that a check test of the water discharge pressure of the fire hydrant can be performed without pouring water into the hose 8.

In particular, when the casing 3 is thinned, the space in the casing 3 is reduced, and this tendency is large.

In order to avoid such a state, it is conceivable that the nozzle cover 101 is detachably attached inside the housing 3 and the nozzle cover 101 is removed when the maintenance valve 19 is used as shown in FIG. (The fire-extinguishing nozzle 16 is attached to the tip of the test hose 21 to perform the test.) However, after the nozzle cover 101 is removed and the maintenance valve 19 is tested, the fire-extinguishing nozzle 16 is held by the nozzle catch 103 again. In addition, it is possible to forget to attach the nozzle cover 101.
If it is forgotten to attach the nozzle cover 101, it is conceivable that dust or the like accumulates on the fire extinguishing nozzle 16 and hinders the fire fighting activity as described above.

  The present invention has been made to solve such a problem, and when the maintenance valve is used, it does not get in the way, and when the fire-extinguishing nozzle is held by the nozzle catch, the nozzle cover covers the upper end surface of the fire-extinguishing nozzle. It aims at providing the fire hydrant apparatus provided with the nozzle cover which does not forget to cover.

[Embodiment 1]
Since the basic structure of the fire hydrant device 1 according to the present embodiment is the same as that shown in FIGS. 7 to 9, the characteristic part of the present invention will be described below with reference to FIGS. 1 to 6. 1 to 6, the same parts as those shown in FIGS. 7 to 9 are denoted by the same reference numerals.

  The fire hydrant device 1 according to the present embodiment includes a nozzle catch 17 that is provided on the mounting surface 20 inside the housing 3 and holds the extinguishing nozzle 16 so that the tip side of the fire-extinguishing nozzle 16 is detachable upward. And a nozzle cover 23 that covers the distal end surface of the fire-extinguishing nozzle 16.

<Nozzle catch>
The nozzle catch 17 holds the fire extinguishing nozzle 16 provided at the tip of the hose 8 when the hose 8 is stored, and is attached to the mounting surface 20 inside the housing 3 so as to be rotatable as shown in FIG. And a holding piece 27 that extends laterally from the turning piece 25 and holds the fire extinguishing nozzle 16. As shown in FIG. 2, the rotating piece portion 25 has a rectangular shape, and a rotating shaft 29 is provided near the eccentric position, specifically, the right corner of the rotating piece portion 25 in the drawing. It is attached to the attachment surface 20 so as to be rotatable about the moving shaft 29. Therefore, the nozzle catch 17 rotates so that the side on which the rotation shaft 29 is provided is up as shown in FIG. 5 in a free state in which the posture is not held by the nozzle cover 23.
The holding piece 27 is formed so that the entire shape has a C shape, and the fire extinguishing nozzle 16 is inserted and held in the C-shaped opening.

<Nozzle cover>
As shown in FIG. 3, the nozzle cover 23 includes a vertical wall portion 30 extending in the vertical direction, a rectangular cover body 31 extending in the horizontal direction from the upper portion of the vertical wall portion 30, and the vertical wall portion 30. A rotation guide portion 33 provided at the lower portion for guiding the rotation of the nozzle catch 17 is provided.
As shown in FIG. 3, the rotation guide portion 33 has a substantially rectangular shape, and has an inclined surface portion 35 that is inclined upward on one side thereof.

  The nozzle cover 23 is attached to the attachment surface 20 in a state where the back side of the vertical wall portion 30 is in contact with the attachment surface 20, and the attachment method will be described. In the following description, “front side” as a word indicating a direction means the front side of the fire hydrant device 1, and “back side” means the back side.

The mounting surface 20 is provided with a slide guide 37 extending from the front side to the back side of the housing 3 (see FIGS. 4 and 5), and the upper end side of the vertical wall portion 30 is brought into contact with the lower surface of the slide guide 37. The vertical wall portion 30 and the rotation guide portion 33 are brought into contact with the slide guide 37 and the holding piece by bringing the lower side of the rotation guide portion 33 into contact with the base portion of the holding piece 27 of the nozzle catch 17 in the horizontal state. The nozzle cover 23 is attached to the attachment surface 20 so as to be sandwiched from above and below by 27. At this time, since the posture of the nozzle catch 17 is maintained by contacting the rotation guide portion 33, the rotation guide portion 33 constitutes the posture holding means of the present invention.
Note that the configuration of the slide guide of the present invention is not limited to the above, and includes, for example, one having a slide groove that slides while being inserted and supported by the upper end of the vertical wall portion 30. Alternatively, the slide groove may be formed by providing a member that forms a gap with the mounting surface 20.

  In the fire hydrant device 1 of the present embodiment configured as described above, when the fire-extinguishing nozzle 16 is held by the nozzle catch 17, the lower surface of the cover body 31 of the nozzle cover 23 is extinguished as shown in FIG. 1. The upper end surface of the nozzle 16 is covered. This can prevent dust from accumulating on the fire extinguishing nozzle 16.

In the state where the fire extinguishing nozzle 16 is removed from the nozzle catch 17, as shown in FIG. 4, the nozzle catch 17 and the nozzle cover 23 are kept as they are.
In this state, since the cover body 31 is disposed below the maintenance valve 19, the test hose 21 may not be attached to the maintenance valve 19 for use. In that case, the nozzle cover 23 is removed so as to be pulled out toward the front side.
By removing the nozzle cover 23, a space is formed below the maintenance valve 19 as shown in FIG. 5, and the test hose 21 and the fire-extinguishing nozzle 16 are attached to the maintenance valve 19 for use as shown in FIG. It becomes possible. Further, since the nozzle catch 17 loses the one that holds the posture, the nozzle catch 17 rotates by its own weight, and the holding piece 27 is in the vertical state as shown in FIG.

  In order to hold the fire-extinguishing nozzle 16 on the nozzle catch 17 after the use of the maintenance valve 19 is completed, it is necessary to return the posture of the nozzle catch 17 to its original position. For this reason, as shown in FIG. 6, the nozzle cover 23 is pushed from the near side toward the far side with the upper end surface of the vertical wall portion 30 being along the lower surface of the slide guide 37. At this time, the inclined surface portion 35 of the rotation guide portion 33 comes into contact with the base portion of the holding piece 27 of the nozzle catch 17 (the portion of the holding piece 27 close to the turning piece portion 25). 2 and the nozzle cover 23 is configured so that the upper end of the vertical wall portion 30 and the lower end of the rotary piece portion 25 are sandwiched between the slide guide 37 and the nozzle catch 17. It is attached to the attachment surface 20.

  Thus, in order to return the posture of the nozzle catch 17 to the original state and hold the fire-extinguishing nozzle 16, the nozzle cover 23 must be attached, and therefore, it is not forgotten to attach the nozzle cover 23.

As described above, according to the present embodiment, the nozzle cover 23 that covers the upper end surface of the fire-extinguishing nozzle 16 is not forgotten and the nozzle cover 23 is detachable. Will not be an obstacle.
In the present embodiment, it is only necessary to push the nozzle cover 23 along the slide guide 37 from the near side to the far side, and the operability of mounting the nozzle cover 23 is excellent.

Furthermore, in this embodiment, since the lower part (the rotation guide part 33) of the nozzle cover 23 is held by the nozzle catch 17, the number of parts is small and the structure is simple.
However, the lower part of the nozzle cover 23 is held by another member provided on the mounting surface 20, and in this state, a locking member that locks the nozzle catch 17 and holds the posture of the nozzle catch 17 is provided on the nozzle cover 23. Also good.

In the above description, an example in which the rotation guide portion 33 is provided on the nozzle cover 23 and the slide guide 37 is provided on the mounting surface 20 is shown, but these are not essential in the present invention.
What hold | maintains the upper side of the vertical wall part 30 of the nozzle cover 23 does not need to be a rail-like thing like the slide guide 37, and the aspect which provides only two protrusions may be sufficient.

  In the above description, the descending door 7 is illustrated as the door body that is attached to the front panel 5 of the fire hydrant device 1 so as to be openable and closable. However, in the fire hydrant device 1 of the present invention, the door body type is particularly There is no limit.
