<Cable storage tube>
The cable storage cylinder 13 is provided between the hinges 30 provided at both ends of the lower side of the forward tilting door 7 and stores the cable 9 connecting the operation lever 11 and the fire hydrant valve.
The cable storage cylinder 13 stores at least the cable 9, but in addition to the cable 9, for example, an electric wire of a limit switch that detects the open / close state of the operation lever 11 may be stored.
The cable storage cylinder 13 is disposed between the hinges 30, and the cable storage cylinder 13 is provided at a position where the axis of the rotation shaft passes. Here, the position where the axis of the rotation axis of the forward tilting door 7 passes is the position where the axis of the rotation axis passes through the cable storage cylinder 13 when the cable storage cylinder 13 is arranged at a certain position. Means that.
Regarding the arrangement of the cable storage cylinder 13, it is preferable that the axis of the cable storage cylinder 13 and the rotation axis of the forward tilting door 7 are parallel, and further the central axis of the cable storage cylinder 13 and the forward tilting door. It is most preferable that the rotation axis 7 coincides with this, and this state is in this embodiment.

The cable storage cylinder 13 of the present embodiment is divided into two in the axial direction, and a fixed cylindrical body 35 attached to the front panel 5 side and a door side cylindrical body 37 attached to the forward tilting door 7 side. It is comprised by two cylindrical bodies.
That is, in FIGS. 1 and 2, the right side in the figure is a door-side cylindrical body 37 attached to the forward tilting door 7 side, and the left side in the figure is a fixed cylindrical body 35 fixed to the front panel 5 side. is there. The fixed cylindrical body 35 and the door side cylindrical body 37 are provided coaxially.
FIG. 3 is a view showing a state in which the lower side portion of the forward tilting door 7 is viewed from directly above with the forward tilting door 7 opened. In FIG. 3, the right side in the figure is a fixed cylindrical body. 35 and the left side in the figure is the door-side cylindrical body 37.

FIG. 4 is a perspective view of the cable housing cylinder 13 in a state in which the forward tilting door 7 is closed.
The fixed cylindrical body 35 fixed to the front panel 5 side is formed with a notch portion 35a in which a part in the circumferential direction of the cylindrical body extends over the entire length in the axial direction, and the front panel extends from the side of the notch portion 35a. A pair of fixing pieces 35b for fixing to 5 is provided at a predetermined interval. When the cable 9 is passed through the gap 35c between the pair of fixed pieces 35b, the fixed piece 35b functions as a guide for routing the cable 9.

  As shown in FIG. 4, the cutout portion 35 a of the fixed cylindrical body 35 is provided on the inner lower half of the peripheral surface of the fixed cylindrical body 35. Since the fixed cylindrical body 35 is fixed to the front panel 5 and does not rotate even when the forward tilting door 7 is opened and closed, the position of the notch 35a is fixed at the position shown in FIG. Therefore, there is always a cylindrical wall on the upper surface of the fixed cylindrical body 35.

The basic shape of the door-side cylindrical body 37 attached to the forward tilting door 7 is the same shape as the fixed cylindrical body 35, and has a notch portion 37a and a pair of fixing pieces 37b, but the total length is fixed. It is set longer than the cylindrical body 35.
The door-side cylindrical body 37 rotates in accordance with the rotation of the forward tilting door 7. At this time, since the fixed cylindrical body 35 and the door-side cylindrical body 37 are coaxial and are in a position through which the rotation axis of the hinge 30 passes, even if the forward tilting door 7 rotates, the door-side cylindrical body 37 and the axis | shaft of the fixed cylindrical body 35 do not shift | deviate large.
In the closed state, the position of the notch 37a in the door-side tubular body 37 is the position of the inner upper half as shown in FIG. 4, and in the fully opened state, the outer lower half as shown in FIG. It becomes the position. Therefore, in the fully open state, the upper surface of the door-side cylindrical body 37 has a cylindrical wall.

  As shown by the arrow shown in FIG. 4, the cable 9 passes through the gap 35 c of the fixed cylindrical body 35 from the inside of the main body 3, passes through the inside of the fixed cylindrical body 35 and the door-side cylindrical body 37, It is drawn from the gap 37c to the forward tilting door 7 side.

  When the forward tilting door 7 is opened and closed with the cable 9 inserted into the cable storage cylinder 13, the door side cylindrical body 37 rotates 180 ° together with the forward tilting door 7, but the fixed cylindrical body 35 moves. Therefore, the cable 9 is twisted in the cable storage cylinder 13. However, since the cable 9 is guided into the main body 3 through the gap 35c, the cable 9 is not violated. Further, the cable 9 is inserted into the cable housing cylinder 13 coaxial with the rotating shaft, and is not greatly violated only by twisting around the axis.

  The action at the time of opening and closing the forward tilting door 7 of the fire hydrant device 1 of the present embodiment configured as described above will be described with reference to FIGS. 5, 6, 8, and 9, other than the front panel 5, the forward tilting door 7, the hinge 30, the cable storage cylinder 13, and the cable 9 are not illustrated.

When the closed state of the forward tilting door 7 is viewed from the front, as shown in FIG. 5, there are hinges 30 at both ends of the lower side of the forward tilting door 7, and the cable housing cylinder 13 is disposed therebetween. The cable 9 is inserted into the cable storage cylinder 13 and cannot be seen from the outside.
When this closed state is viewed from the inside of the main body 3, the cable 9 inserted through the cable storage tube 13 can be seen from the notches 35 a and 37 a of the cable storage tube 13 as shown in FIG. 6. Similarly to FIG. 6, when the cable housing cylinder 13 in the closed state is viewed from the inside of the main body 3, it is as shown in FIG.

When the forward tilting door 7 is opened, the door is rotated by about 180 ° to be fully opened as shown in FIG. At this time, as shown in FIG. 8, the door-side tubular body 37 is in a state in which the notched portion 37 a faces the front. When this state is viewed from the inside of the main body 3, as shown in FIG. 9, the cutout portion 35 a of the fixed cylindrical body 35 faces toward the inside front, and the cable 9 can be seen therefrom.
When this state is viewed from directly above, as shown in FIGS. 3 and 10, the upper surface of the cable housing cylinder 13 is not positioned with the notches 35 a and 37 a, and the cylinder wall is present. Therefore, as shown in FIG. 2, when the hose 15 is pulled out, there is a cylindrical wall of the cable storage cylinder 13 regardless of the position of the lower side of the forward tilting door 7, and the cable 9 and the hose 15 does not interfere.

  In the present embodiment, the cable storage cylinder 13 is divided into two parts and the fixed cylindrical body 35 is provided on the front panel 5 side. Therefore, the cable 9 is always guided by the fixed cylindrical body 35 and the gap 35c is formed. It passes and is drawn around inside the main body 3. For this reason, when the forward tilting door 7 is opened and closed, the cable 9 is twisted by 180 ° around the axis in the cable housing cylinder 13, so that the cable 9 outside the cable housing cylinder 13 is largely twisted. There is nothing. In particular, since the cable 9 is drawn into the main body 3 via the fixed cylindrical body 35, the cable 9 is not violated in the main body 3, and a predetermined route routed can be maintained.

In the above-described embodiment, an example in which the cable storage cylinder 13 is divided into two parts is shown. However, the cable storage cylinder 13 of the present invention may be one that is not divided. In that case, it may be attached to either the front panel 5 side or the forward tilting door 7 side.
In the above embodiment, the cable storage tube 13 is provided with the axial cutout portions 35a and 37a to facilitate the storage of the cable 9. However, the cable storage tube 13 may have no cutout portion. . On the contrary, when the notch portion is provided and the cable storage cylinder is attached to the forward tilting type door 7, when the forward tilting type door 7 is opened, the notch portion is not positioned above, It is necessary to have a cylindrical wall above.

  In the above embodiment, the forward tilting door opens 180 ° in the fully open state, but the forward tilting door in the fire hydrant device of the present invention is not limited to this, and the rotation angle when fully open There is no limitation, and for example, a forward tilting door may be attached to the lower part of the front panel and opened 90 ° when fully open.
