It has a front panel 5 having an opening 5a provided, and a forward tilting door 7 provided openably and closably in the opening 5a of the front panel 5.
Each configuration will be described in detail below.

<Body>
As shown in FIGS. 1 to 3, the main body 3 has a rectangular box-shaped casing, and a hose storage portion 9 and a hose storage portion 9 for storing the hose 8 wound in an inner winding in the casing. A central opening 11 is provided for pulling out the hose 8 stored therein. Further, a piping system 12 having a fire hydrant valve and an automatic pressure regulating valve is provided on the right side of the hose storage portion 9 in the housing. The distal end side of the piping system 12 is connected to the proximal end side of the hose 8 and the proximal end side is connected to a water supply source (not shown).

ホ ー ス Hose storage section》
The hose storage portion 9 includes two rod-like members 13 extending from the upper surface to the lower surface of the inner wall of the main body 3 and two strip plates 15 bent in a substantially L shape from the rod-like members 13 to the inner surface rear surface of the main body 3 It is configured to be equipped.
Then, a central opening 11 is formed between the two rod-like members 13, and the hose 8 is pulled out from here.

<Front panel>
The front panel 5 is provided on the front surface of the main body 3 and has a portion located forward of the central opening 11 open, and the forward tilting door 7 is attached so as to close the opening 5a.

<Forward-inclined door>
The front tilting door 7 is in the form of a horizontally long rectangular formed of a plate-like metal plate, and is attached so as to be able to close the opening 5a of the front panel 5 as described above.
The forward tilt door 7 is provided with pivots at both ends of the lower side 7b, and from the closing state of the opening 5a, as shown in FIG. 2 and FIG. You can open up to the state.

In the present invention, the height of the front tilting door 7 is not limited, but it is desirable that the height of the protruding amount from the inspection path 53 does not exceed the construction limit at the time of opening. For example, the height of the front tilting door 7 Is preferably set to half or less of the height of the front panel 5. Alternatively, the actual dimension of the height of the anteversion-type door 7 is preferably, for example, 380 mm to 430 mm, in other words, the amount (length) of protrusion from the front surface (front panel 5) of the fire hydrant device 1 at the time of opening For example, it is preferable to set it as 300 mm-350 mm.
On the back side of the forward-tilting door 7, a nozzle fixing portion 17 for detachably fixing the fire extinguishing nozzle 16, a hose guide 19 serving as a guide when pulling out the hose 8, and an operation lever 20 for opening and closing the fire hydrant valve are provided. ing.

<< Nozzle Fixing Part >>
The nozzle fixing portion 17 fixes the fire extinguishing nozzle 16 provided at the tip of the hose 8 when the hose is stored, and is formed of, for example, a C-shaped locking piece 17 a called a nozzle catcher. And as shown in FIG. 2, the nozzle 16 for fire extinguishing is fixed so that the axial center direction may become substantially parallel to the width direction of the front tilting door 7. As shown in FIG.
The position of the nozzle fixing portion 17 is preferably provided as close to the upper side 7 a of the forward tilting door 7 as possible as long as the handle 16 a of the fire extinguishing nozzle 16 does not protrude from the forward tilting door 7 when stored. The reason is that since the length from the fire extinguishing nozzle 16 to the hose storage portion 9 can be secured when the hose is stored, the hose 8 can be stored without applying an excessive force.
In addition, although the state shown in FIG. 2 opened the front inclination type door 7, it is a state before removing the fire-extinguishing nozzle 16 from the nozzle fixing part 17, and direction of the hose guide 19 closed the front inclination type door 7. It is the same as the state. On the other hand, the state shown in FIG. 3 is a state after the forward tilting door 7 is opened and the fire extinguishing nozzle 16 is removed from the nozzle fixing portion 17, and the direction of the hose guide 19 is the same as FIG. It is oriented.

ホ ー ス Horse guide》
As shown in FIG. 4, the hose guide 19 has a predetermined distance from the first vertical side 19a via the horizontal side 19c and the first vertical side 19a erected on the back side of the forward tilting door 7. , And the entire shape is an inverted U-shape.
The hose guide 19 is, as shown in FIG. 1, inside the hose 8 stored in the central opening 11 of the hose storage portion 9, more specifically, in the hose storage portion 9 when the forward tilting door 7 is closed. Be placed. The lateral side 19 c may be arched or straight.

The lower end of the first vertical side portion 19a is rotatably attached to the forward tilting door 7 via a bearing 23, as shown in FIG. In addition, at the lower end portion of the first vertical side portion 19a, a locking portion 24 that locks to a stopper 27 described later is provided.
Furthermore, a weight 25 is attached to the lower end of the second vertical side portion 19 b and a gap S is formed between the weight 25 and the forwardly tilting door 7. Therefore, the hose guide 19 can be moved from the position near the upper side 7a of the front tilting door 7 to the position near the lower side 7b by rotating the first vertical side 19a. ing.

Further, at the lower end of the first vertical side portion 19a, two stoppers 27 are provided for restricting the rotation angle of the first vertical side portion 19a by being locked to the locking portion 24. For this reason, as shown in FIG. 5, the first vertical side portion 19a can be turned within a range of 90 °. More specifically, as shown in FIG. 5 (a), from the state where the side 19c becomes horizontal, as shown in FIG. 5 (b), the side 19c turns so as to face vertically downward. it can. That is, the stopper 27 is an outer peripheral portion of the lower end of the first vertical side portion 19 a so that the stopper 27 is provided on the forward tilting door 7 and can be locked to the locking portion 24. It is arranged at the position corresponding to the locus. Then, the stopper 27 is engaged with the locking portion 23 at a position where the horizontal side 19 c is in a horizontal state and a position where the horizontal side 19 c is in a vertically downward direction.
The reason why the hose guide 19 can be pivoted about the first longitudinal side 19a is as follows.

The main role of the hose guide 19 is to make it easy to withdraw the hose 8 when pulling out the hose 8 and to prevent the hose 8 from unwinding. Therefore, in a state where the hose 8 is drawn out, that is, in a state where the front tilting door 7 is opened, as shown in FIG. 6A, the first vertical side 19a and the second vertical side 19b are aligned in a horizontal line. It is preferable to move to the upper side 7a.
On the other hand, in a state in which the front tilting door 7 is closed, the hose 8 interferes with the second vertical side 19 b in a state where the first vertical side 19 a and the second vertical side 19 b are aligned in a straight line in the horizontal direction. I will. Therefore, in a state where the front tilting door 7 is closed, as shown in FIG. 6B, the second vertical side portion 19b moves to the lower side 7b side of the front tilting door 7, and the first vertical side portion 19a and By arranging the second vertical side portions 19 b in a straight line in the vertical direction, it is possible to prevent the hose 8 from interfering with the second vertical side portions 19 b.
Although FIG. 6 (b) shows the state in which the front tilting door 7 is opened, this is for explaining the direction of the hose guide 19 in the state in which the front tilting door 7 is closed, and Thus, in the state where the forward tilting door 7 is closed, the direction of the hose guide 19 is as shown in FIG. 6 (b).

The operation at the time of extinguishing the fire hydrant device 1 of the present embodiment configured as described above will be described.
When a fire occurs in the tunnel 51, the operator first opens the forward tilting door 7 to the front side (the side of the road 52) to open the door, and the forward tilting door 7 rotates about 90 degrees, The tilting door 7 is substantially parallel to the inspection path 53.

  The operator operates the operating lever 20 to open the fire hydrant valve to supply extinguishing water to the hose 8, removes the extinguishing nozzle 16 from the nozzle fixing portion 17, and pulls out the hose 8 in the direction of the fire Firefighting activities. When the hose 8 is pulled out, in the fire hydrant device 1 according to the present embodiment, as shown in FIG. 6A, the hose guide 19 rotates about the first vertical side 19a, and the horizontal side 19c is By being parallel to the upper side 7a of the anteversion-type door 7 (moving closer to the upper side 7a), the second vertical side portion 19b on the withdrawal side of the hose 8 is disposed at a position away from the central opening 11, Since the distance from the opening 11 is increased, a smooth hose can be drawn without requiring an excessive drawing force.

  On the other hand, in the state where the hose 8 is stored, when the forward tilting door 7 is closed, the first vertical side portion 19a is rotated by the gravity acting on the weight 25 attached to the second vertical side portion 19b. The two vertical sides 19 b are disposed vertically below the first vertical side 19 a (move closer to the lower side 7 b). Therefore, in the state where the fire extinguishing nozzle 16 is fixed to the nozzle fixing portion 17, the second vertical side portion 19b and the hose 8 do not interfere with each other, and the hose 8 does not jump out from the upper side 7a of the forward tilting door 7.

  In the above description, the height of the front tilting door 7 is not limited, and the application of the present invention to one having a high height of the front tilting door as in the conventional example is excluded. However, as described above, when the present invention is applied, the storability of the hose 8 and the draw-out performance of the hose 8 are excellent even when the height of the anteversion door is lowered, and the height is high. By applying the invention to a low forward inclination type door, the effect that the tip of the forward inclination type door can surely be prevented from exceeding the width of the inspection path 53 can be achieved.

In the above description, the weight 25 is provided in the second vertical side 19b, and the example in which the first vertical side 19a is rotated by gravity acting on the weight 25 has been described. The weight 25 may be unnecessary as long as the first longitudinal side 19a can be rotated by the acting gravity (self weight).
In the above description, the nozzle fixing portion 17 fixes the extinguishing nozzle 16 so that the axial direction thereof is substantially parallel to the width direction of the front tilting door 7. It is not limited to. For example, the distal end side of the fire extinguishing nozzle 16 may be fixed so that the distance from the upper side 7 a of the front tilting door 7 is closer to the pivot axis of the front tilting door 7 than the base end.

Second Embodiment
The hose guide 19 of the first embodiment rotates the first vertical side 19a by the gravity acting on the weight 25 provided on the second vertical side 19b, but the hose guide 29 of the present embodiment is the same as the hose guide 29 of the first embodiment. The first vertical side portion 29a of the hose guide 29 is rotated in conjunction with the opening and closing operation of the front tilting door 7.
Therefore, as shown in FIG. 7, the hose guide 29 has a first longitudinal side 29a, a second longitudinal side 29b, and a horizontal side 29c, and the first longitudinal side 29a can be pivoted forward. Although attached to the door 7, the weight 25 provided in the hose guide 19 of the first embodiment is not provided. On the other hand, a wire 31 (a first wire 31a and a second wire 31b) for rotating the first vertical side 29a is attached to the base end of the first vertical side 29a.
Moreover, the drive force conversion mechanism 32 which converts the movement of the front tilting door 7 at the time of opening and closing into the drive force which rotates the 1st vertical side part 29a is provided (refer FIGS. 8-10).

  The driving force conversion mechanism 32 has a rotation support shaft 33 fixed at one end to the housing and rotatably supporting the forward tilting door 7, and a rotation support shaft 33 provided at an end on the forward tilting door 7 side. (1) A driven shaft member 39 having a bevel gear 35 and a second bevel gear 37 meshing with the first bevel gear 35 at its tip and whose base end is rotatably attached to the forward tilting door 7, and one end is a driven shaft member A wire 31 is provided, which is attached to the other end 39a of the first longitudinal side 29a and transmits the rotational force of the driven shaft member 39 to the first longitudinal side 29a.

In the present embodiment, the wire 31 transmits the first wire 31a for transmitting the movement at the time of opening the front tilting door 7 to the first vertical side portion 29a and the movement at the closing of the front tilting door 7 as the first wire 31a. It consists of two wires 31 of the 2nd wire 31b transmitted to 1 vertical side 29a.
The tip portions of the first wire 31a and the second wire 31b are fixed to the outer peripheral surfaces of the driven shaft member 39 and the first vertical side portion 29a, respectively. Therefore, when the driven shaft member 39 rotates, the first wire 31a and the second wire 31b are wound around the driven shaft member 39, whereby a tensile force is applied to the first wire 31a and the second wire 31b. When this tensile force acts on the first vertical side 29a, the first vertical side 29a rotates.

In the present embodiment configured as described above, when the forward tilting door 7 pivots about the rotation support shaft 33, the second bevel gear 37 revolves around the axis of the first bevel gear 35 while rotating on its own axis. The driven shaft member 39 rotates. The rotational force of the driven shaft member 39 is transmitted to the first vertical side portion 29 a via the two wires 31.
For example, in the case of the operation of opening the forward tilting door 7, as shown in FIG. 10 (a), when the driven shaft member 39 is rotated counterclockwise as shown in FIG. 31a is pulled, this tensile force is transmitted to the first longitudinal side 29a, and the first longitudinal side 29a rotates counterclockwise in FIG. 10 (b). As a result, the second vertical side portion 29a moves in the direction of arrow A in FIG. 10 (b), and the horizontal side member 29c is parallel to the upper side 7a of the front tilting door 7 (moved closer to the upper side 7a) (See FIG. 6 (a)).

  Conversely, when the forward-tilting door 7 is closed, as shown in FIG. 10A, when the driven shaft member 39 rotates and the driven shaft member 39 rotates, the second wire 31b is rotated. The pulling force is transmitted to the first longitudinal side 29a, and the first longitudinal side 29a rotates clockwise in FIG. 10 (b). As a result, the second vertical side portion 29b moves in the direction of arrow B in FIG. 10 (b), and the horizontal side member 29c is perpendicular to the upper side 7a of the front tilting door 7 (moves closer to the lower side 7b) (See FIG. 6 (b)).

  In addition, since the rotation angle of the front tilting door 7 is 0 to 90 ° and the rotation angle of the hose guide 19 is also 0 to 90 °, it is not necessary to adjust the rotation angle by the gear. The number of teeth of the bevel gear 35 and the second bevel gear 37 may be the same.

  As described above, according to the present embodiment, the direction of the hose guide 29 can be reliably changed to an appropriate direction by the opening / closing operation of the forward tilting door 7.

Third Embodiment
In the fire hydrant device 40 of the present embodiment, the first vertical side 41a and the second vertical side 41b of the hose guide 41 move together toward the upper side 7a and the lower side 7b with respect to the forward tilting door 7. While being possible attachment, it is constituted so that it may move in response to the opening and closing operation of the forward tilting door 7 (see FIGS. 11 and 12). In FIGS. 11 and 12, the same reference numerals as in FIGS. 1 and 2 denote the same parts in FIG.

  The fire hydrant device 40 includes a hose guide moving mechanism 43 for moving the hose guide 41 in accordance with the movement of the forward tilting door 7 at the time of opening and closing (see FIGS. 13 to 16). In FIGS. 13 to 16, members common to the members described in the second embodiment are denoted by the same reference numerals.

  The hose guide moving mechanism 43 has a rotation support shaft 33 fixed at one end side to the housing and rotatably supporting the forward tilting door 7, and a second support provided at an end of the rotating support shaft 33 on the forward tilting door 7 side. A driven shaft member 39 having a first bevel gear 35 and a second bevel gear 37 meshing with the first bevel gear 35 at its tip and whose base end is rotatably attached to the forward tilting door 7; A driven gear 45 provided on the shaft portion, a pinion gear 47 rotating in mesh with the driven gear 45, and a rack 49 horizontally moved by the pinion gear 47 are provided. The hose guide 41 is attached to the rack 49, and the horizontal movement of the rack 49 causes the horizontal movement of the hose guide 41.

  In the present embodiment configured as described above, when the forward tilting door 7 pivots about the rotation support shaft 33, the second bevel gear 37 revolves around the axis of the first bevel gear 35 while rotating on its own axis. The driven shaft member 39 rotates. When the driven shaft member 39 rotates, the driven gear 45 rotates, the pinion gear 47 meshing with this rotates, the rack 49 horizontally moves, and the hose guide 41 attached to the rack 49 horizontally moves (FIG. 16). reference).

For example, in the case of the operation of opening the forward tilting door 7, as shown in FIG. 16A, the driven gear 45 rotates counterclockwise in the figure, and the pinion gear 47 meshing with this rotates clockwise. . By rotation of the pinion gear 47, the rack 49 moves downward in the figure, and the hose guide 41 attached to the rack 49 moves downward in the figure, that is, closer to the upper side 7a of the forward tilting door 7 (FIG. a) see).
As the hose guide 41 moves closer to the upper side 7a of the forwardly tilting door 7, the distance from the central opening 11 to the hose guide 41 becomes longer, and the bending radius of the hose 8 when pulling out the hose 8 can be increased. Since the force required to withdraw the hose 8 can be reduced, smooth withdrawal of the hose 8 becomes possible.

  When the forward tilt door 7 is closed, as shown in FIG. 16B, the driven gear 45 rotates clockwise in the drawing, and the pinion gear 47 meshing with this rotates counterclockwise. By rotation of the pinion gear 47, the rack 49 moves upward in the figure, and the hose guide 41 attached to the rack 49 moves upward in the figure, that is, toward the lower side 7b of the forward tilting door 7 (FIG. b) see). By moving the position of the hose guide 41 closer to the lower side 7b of the front tilting door 7, the second vertical side portion 41b and the hose 8 do not interfere with each other in a state where the fire extinguishing nozzle 16 is fixed to the nozzle fixing portion 17. The hose 8 does not pop out from the upper side 7 a of the front tilting door 7.
