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

FIG. 1 shows a housing 10 and a guard fence gf arranged in a tunnel. As shown in FIG. 1, the housing 10 may be arranged so as to be embedded in the tunnel inner wall iw on the side of the observer passage pw provided on the shoulder of the road rw. 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 housing 10 according to the present embodiment is not limited to the arrangement shown in FIG. 1, and 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 housing 10 is provided with a hinged door, the hinged door opened during the fire extinguishing activity protrudes to the observer passage pw side or the road rn side, and the fire extinguishing activity or the evacuation activity in the observer passage pw or the road rn. May cause problems. 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.

In order to eliminate the above concerns, the housing 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 door that opens and closes in the vertical direction closes due to its own weight, it is less susceptible to the effects of earthquakes and shaking caused by the running of the vehicle compared to hinged doors and doors that open and close in the horizontal direction, and the door can be opened without operation. It is possible to effectively reduce the possibility of the door being damaged.

Furthermore, when the above-mentioned hinged door is tilted forward and opened, the operator may get on the hinged door during work to prevent rattling when pulling out the hose. It was necessary to make the door sturdy, such as by using two metal plates. 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.

Here, in order to open and close the door in the vertical direction and fix it in the open state, for example, an auxiliary device such as a gas spring or a hydraulic damper as disclosed in Patent Document 1 can be used. .. However, in this case, the structure of the housing becomes complicated and the manufacturing cost increases significantly. Furthermore, when using the auxiliary device as described above, regular maintenance of the auxiliary device is also required.

On the other hand, for example, by applying the structure disclosed in Patent Document 2, it is possible to raise the door while preventing the door from descending. However, in the structure disclosed in Patent Document 2, since the uppermost paragraph bottom prevention state is automatically released, there is a possibility that the door will be unintentionally lowered when operated by an operator who does not know the structure. There is. Further, in the structure disclosed in Patent Document 2, there is no means for releasing the fall prevention state other than raising the door to the uppermost stage, and there is room for improvement in convenience.

The housing 10 according to the embodiment of the present invention was conceived by paying attention to the above points, and can effectively enhance safety and convenience with a simple structure.

Further, a first pressing member 230 and a second pressing member 235 are attached to the stopper 220 according to the present embodiment. The first pressing member 230 according to the present embodiment is a component that presses the stopper 220 in the direction of the door guide 300 with the first rotating shaft 226 as a fulcrum. According to the first pressing member 230 according to the present embodiment, the stopper 220 is always pressed toward the door guide 300 when the door 200 is raised, so that the tip of the stopper 220 gets over the first protrusion 320. Also returns to the position where it comes into contact with the door guide 300. According to this, even when the operator separates the handle 202 of the door 200, the tip end portion of the stopper 220 is locked by the first protrusion 320 located below, and the lowering of the door 200 is stopped. Therefore, it becomes possible to work more safely.

On the other hand, when the door 200 is lowered, the stopper 220 is required to be fixed at a position where it does not come into contact with the door guide and the first protrusion 320. In order to release the lowering prevention state of the door 200, the operator can rotate the stopper 220 by pulling the lever 222 toward the center side of the door 200 and fix the fixed portion 224 to the stopper fixing member 240. .. At this time, the second pressing member 235 makes the fixed portion 224 rotatable about the second rotating shaft 228 as a fulcrum, so that the fixed portion 224 starts contacting the stopper fixing member 240 and the lever is started. After being bent to the 222 side, it is returned to its original position after rotation.

The tip portion of the fixed portion 224 may be formed in a ring shape, for example, and may be fitted with a stopper fixing member 240 provided on the door 200. According to the above configuration, it is possible to prevent the stopper 220 from coming into contact with the first protrusion and being locked, so that the door 200 can be lowered. The first pressing member 230 and the second pressing member 235 are formed by using, for example, a spring or the like.

Further, a fixing release member 330 is provided at the lower part of the housing 10. When the door 200 moves to the lowering position (lowering limit position), the fixing release member 330 according to the present embodiment comes into contact with the fixed portion 224 as the door 200 lowers, and the stopper 220 by the stopper fixing member 240 It is a configuration to release the fixed state of.

The components included in the housing 10 according to the present embodiment have been described above. Next, the operation of the housing 10 when the door 200 is opened and closed according to the present embodiment will be described in detail.

FIG. 4 is a diagram for explaining the operation of the housing 10 when the door 200 is raised according to the present embodiment. In the upper part of FIG. 4, changes in the appearance state as the door 200 rises are shown in order from the left. Further, in the lower part of FIG. 4, an enlarged view of the region a in each state shown in the upper part is shown.

When the door 200 is raised from the center of FIG. 2 and the lowering position shown in FIG. 3, the tip of the stopper 220 becomes the door guide 300 as the door 200 rises, as shown on the far left in the lower part of FIG. It comes into contact with the first protrusion 320 provided and rides on the side surface of the first protrusion 320.

When the door 200 is further raised from this state, the tip end portion of the stopper 220 gets over the side surface of the first protrusion 320, as shown second from the left in the lower part of FIG. At this time, the first pressing member 230 is installed on the upper surface of the first protrusion 320 by pressing the stopper 220 in the direction of the door guide 300 with the first rotating shaft 226 as a fulcrum.

In this state, the stopper 220 is locked by the first protrusion 320, so that the door 200 is fixed and the lowering prevention state is established. According to such a mechanism, even if the operator unintentionally releases his / her hand from the handle 202 during the raising operation of the door 200, the door 200 is prevented from being lowered and the work is performed more safely. It becomes possible.

As described above, a plurality of the first protrusions 320 according to the present embodiment may be provided in the door guide 300, and the number and the interval can be arbitrarily set. Further, the first protrusion 320 may be detachably provided on the door guide 300, and in this case, an operator such as a maintenance worker can adjust the position for fixing the door 200 according to the situation.

From here, when the door 200 is further raised and the door 200 reaches the raised position (rising limit position), the retaining member 245 provided at the lower part of the door 200 is provided as shown second from the right in the lower part of FIG. Touches the lower surface of the second protrusion 325 provided on the door guide 300, so that the door 200 stops ascending. According to such a mechanism, it is possible to prevent the door 200 from being unintentionally raised to the removal position and the door 200 from being detached from the housing 10.

In the above state, when the operator releases the handle 202 or operates the handle 202 to lower the door 200, the second protrusion 325 is used as shown on the far right of the lower part of FIG. The door 200 is fixed in the fully open state by locking the stopper 220 by the first protrusion 320 arranged above. The size of the opening in the fully open state can be arbitrarily set by adjusting the position of the first protrusion 320. For example, when the door 200 is a fire extinguisher door or a fire hydrant door, the first protrusion 320 is arranged so that the opening in the fully opened state is about 700 mm so that the hose can be taken out and the fire extinguisher can be taken out sufficiently. May be good.

Next, the operation of the housing 10 when the door 200 is lowered according to the present embodiment will be described. FIG. 5 is a diagram for explaining the operation of the housing when the door 200 is lowered according to the present embodiment.

In the above state, the operator uses the other hand different from the one that operates the handle 202, and as shown second from the right in the lower part of FIG. 4, the lever 222 of the stopper 220 is placed on the center side of the door 200. Pull to. At this time, by the above operation on the lever 222, the stopper 220 rotates, and the fixed portion 224 comes into contact with the stopper fixing member 240. Further, the fixed portion 224 is bent toward the lever 222 side when the contact with the stopper fixing member 240 is started.

Here, when the operator further pulls the lever 222 toward the center of the door 200, the fixed portion 224 that has overcome the convex portion of the stopper fixing member 240 is the second, as shown second from the left in the lower part of FIG. By pressing with the pressing member 235, the door returns to the original position and fits with the stopper fixing member 240.

According to the mechanism as described above, it is possible to prevent the stopper 220 from coming into contact with the first protrusion and being locked, so that the door 200 can be lowered. Further, unlike the mechanism disclosed in Patent Document 2, in the present invention, since an operator's intentional operation is required to release the lowering prevention state, the lowering prevention state is unintentionally released and the door is released. It is possible to avoid the situation where the 200 falls.

Further, since the stopper 220 according to the present embodiment is arranged on the back surface of the extension portion provided at the lower ends on both sides of the door 200, the operator does not have to reach deep inside the housing 10. If necessary, the door 200 can be easily released from the lowering prevention state by one-handed operation while visually observing.

Subsequently, when the door 200 is lowered with the stopper 220 fixed by the stopper fixing member 240, as shown on the far left in the lower part of FIG. 5, the housing is before reaching the lowering position (lowering limit position). The fixing release member 330 provided at the lower part of the body 10 comes into contact with the fixed portion 224 of the stopper 220.

When the door 200 is further lowered from this state, the fixing release member 330 pushes up the fixed portion 224 to release the fitting with the stopper fixing member 240. At this time, the first pressing member 230 presses the stopper 220 toward the door guide 300, so that the stopper 220 returns to the state of being in contact with the door guide 300 as shown in FIG.

According to the mechanism as described above, when the door 200 is in the lowered position, it can be automatically returned to the lowered preventive state, eliminating human error such as forgetting the return operation by the operator and improving safety. It can be further enhanced.
