Further, as a mechanism for assisting the opening and closing, there is a gas spring 61 which is an example of an urging means installed between the lower surface of the first plate member 37a and the bottom surface of the main body 11, and the first is always the first. A force is given to push the plate member 37a upward, that is, upward (see FIG. 13).
If the gas spring 61 is extended too much, the first plate member 37a is inclined to the back side when the top plate portion 37 is fully opened. Therefore, a rod-like stopper 65 is provided to prevent this. As shown in FIG. 13, the stopper 65 is inserted into a long hole 63 provided in the wheel running surface portion 53, the upper end thereof is connected to the upper end of the gas spring 61, and a hook 65 a is formed at the lower end. When the gas spring 61 is extended and fully opened, the hook 65a is engaged with the lower surface of the wheel running surface portion 53 so that the gas spring 61 is not further extended.
The urging force of the gas spring 61 is smaller than the pressing force due to the weight of the top plate portion 37, and assists the opening of the top plate portion 37.

In the fully opened state shown in FIGS. 11 and 12A, the first plate member 37a is in a substantially vertical state. In this state, the top plate portion 37 is opened in the opening direction by the urging force of the gas spring 61. Because it is energized, it does not close by its own weight.
When the top plate portion 37 is closed from the state shown in FIGS. 11 and 12A, if the handle 51 is grasped and the second plate member 37b is pulled to the front, the weight of the top plate portion 37 is pulled. The force is greater than the urging force of the gas spring 61, and the wheel 55 travels smoothly on the horizontal surface portion 53a of the wheel travel surface portion 53, thereby smoothly moving the door. At this time, the urging force of the gas spring 61 is resisted, but the first plate member 37a and the second plate member 37b are steel plates, and since there is a weight, this weight becomes a downward force, so that the operator There is no need to apply a strong force.

When the wheel 55 travels on the horizontal surface portion 53a and moves to the position of the stopper 59, the movement of the wheel 55 is restricted and stopped. As shown in FIGS. 12 (b), 13, 14, and 15, The plate portion 37 stops in a half-open state.
At this time, a gap larger than the thickness of the finger is formed between the front side of the second plate member 37b and the main body 11 and between the side sides of the first plate member 37a and the second plate member 37b and the main body 11. It has come to be. For this reason, if the top plate portion 37 is closed at a stretch, there is a risk that fingers or the like may be pinched between the top plate portion 37 and the main body portion 11, but the fire hydrant device 41 of the present embodiment avoids this risk. It is excellent in safety.

In order to completely close the top plate portion 37 from the above state, the handle 55 is held and the second plate member 37b is slightly lifted so that the wheel 55 gets over the stopper 59.
When the top plate portion 37 is completely closed, the wheels 55 are stored in the wheel storage space 57, and the top plate portion 37 is completely closed with the top plate portion 37 being horizontal as shown in FIG. It becomes a state.
At this time, as shown in FIG. 12C, the V-shaped groove 49 is formed, and the groove width is wider than the thickness of the finger, so there is no danger of clogging the V-shaped groove.

  In addition, in order to open the top plate part 37 from the closed state, the handle 51 is held and the second plate member 37a is lifted so that the connecting part of the first plate member 37a and the second plate member 37b has a mountain shape. What is necessary is just to slide the near side edge part of the plate member 37b toward the back side.

  Also in the fire hydrant device 41 of the present embodiment, as described in the second embodiment, as shown in FIG. 16, a step 35 is provided above the hose 3 in the hose storage portion 5 of the main body 11, In a state where the plate portion 37 is opened, it is preferable to step into the main body portion 11 so that smooth passage is possible.
