It is a figure for demonstrating the arrangement example of the road fire hydrant which concerns on one Embodiment of this invention. The external structure of the road fire hydrant according to the same embodiment when viewed from the front is shown. It is a figure which shows the internal structure of the road fire hydrant which concerns on this embodiment. It is a figure for demonstrating the operation when each door which concerns on the same embodiment is fully opened.

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the present specification and the drawings, components having substantially the same functional configuration are designated by the same reference numerals, so that duplicate description will be omitted.

<1. Embodiment>
<< 1.1. Overview >>
First, an outline of the road fire hydrant 10 according to the embodiment of the present invention will be described. The road fire hydrant 10 according to the present embodiment may be installed in a tunnel, for example. FIG. 1 is a diagram for explaining an arrangement example of the road fire hydrant 10 according to the present embodiment.

FIG. 1 shows a road fire hydrant 10 and a guard fence gf arranged in a tunnel. As shown in FIG. 1, the road fire hydrant 10 may be arranged so as to be embedded in the tunnel inner wall iwa on the side of the observer passage pw provided on the shoulder of the road rn. Here, the observer passage pw is generally provided at a height of about 900 to 1000 mm from the road rn, and is used as a maintenance work by an observer or an evacuation route in the event of a disaster.

Further, the arrangement is not limited to that shown in FIG. 1, and the road fire hydrant 10 according to the present embodiment may be arranged at the boundary between the road rn and the observer passage pw like the guard fence gf.

Here, for example, when the road fire hydrant 10 is provided with a hinged door that expands to the left and right, or a hinged door that tilts forward to open the door, the hinged door opened during the fire extinguishing activity is on the guard passage pw side or the road rn side. It will protrude, and there is a possibility that fire extinguishing activities and evacuation activities in the observer passage pw and road rh will be hindered. In addition, even during maintenance work, the hinged door protrudes toward the observer passage pw side and the road rn side, obstructing the flow lines of the maintenance personnel and vehicles traveling on the road rn, resulting in a decrease in work efficiency and safety. That is also a concern.

Furthermore, in the case of a hinged door that tilts forward and opens to the front side, the installation location is limited because the possibility that the contents such as the fire extinguisher stored inside will jump out of the housing when the door is opened cannot be ignored. Was there.

In order to eliminate the above concerns, the road fire hydrant 10 according to the present embodiment may have a door that opens and closes while sliding in the vertical direction instead of the hinged door. According to the above configuration, it is possible to prevent the door from protruding toward the observer passage pw side or the road rw side during fire extinguishing activities or maintenance work, and it is possible to further improve safety and convenience. In addition, since the doors that open and close in the vertical direction are closed by their own weight, they are less susceptible to shaking and wind caused by earthquakes and vehicle running, compared to hinged doors and doors that open and close in the horizontal direction, and magnets and latches. Even when there is no fixing device such as a formula, it is possible to effectively reduce the possibility of opening the door without operation.

Furthermore, when the above-mentioned hinged door is tilted forward to open, it is made of metal in consideration of preventing rattling when pulling out the hose and allowing the operator to get on the hinged door during work. Since it was necessary to make the door sturdy, such as by using two plates, the weight of the door tended to be heavy. On the other hand, in the case of a door that opens and closes in the vertical direction, it is difficult to assume the above situation, so that the weight of the door can be reduced. In addition, as the weight is reduced, it is possible to use a transparent material such as acrylic for the door instead of a metal material such as stainless steel. In this case, the state of the stored items does not require the observer to open the door each time. Can be visually confirmed, and the effect of improving work efficiency is also expected.

Even if a sliding door that slides in the left-right direction to open the door or a drop-type door in which the door falls downward is provided, it is expected that some of the effects described above will be exhibited. However, for example, when a plurality of doors are provided for a road fire hydrant, if doors having different opening / closing styles are adopted,
There is concern that the operator who extinguishes the fire for the first time may be confused by the operation of opening the door.

Even if the opening and closing styles of all the doors are unified, if the shapes and sizes of the doors are different, it is expected that the efficiency of maintenance work will decrease and the manufacturing cost of each door will increase.

The road fire hydrant 10 according to the embodiment of the present invention was conceived by paying attention to the above points, and makes it possible to effectively enhance safety and convenience with a simple structure.
