Conventionally, the damper is of a type that supports the fire hydrant door by an arm-like support portion Is used (see Patent Document 1). In recent years, although the thinning of the case has progressed, the damper of the type used in the prior art is entirely housed in the case including the arm-like supporting portion when the door is closed. Requires a space for storing the damper. That is, conventionally used types of dampers are an obstacle to thinning the housing.

  SUMMARY OF THE INVENTION In view of the above-described circumstances, the present invention is directed to a fire hydrant device having a fire hydrant door that opens and closes an outlet of a fire extinguishing hose on a front surface of a housing, so that the moment of the fire hydrant door can be reduced. I assume. Another object of the present invention is to make it possible to reduce the thickness of the housing while providing a damper.

  In the present invention, the first invention (the invention according to claim 1 and its dependents) is rotatably attached by a hinge to an outlet of a fire extinguishing hose provided on a front surface of a housing, and the outlet is The fire hydrant device according to claim 1, wherein the fire hydrant door has a component attachment position at a position close to the hinge.

  In the first aspect of the present invention, the hinge can be a damper hinge having a damper for controlling a rotational operation. Further, the fire hydrant door may have a projecting edge projecting to the content of the door at an end edge closer to the hinge, and may have a mounting position of the component at the projecting edge. Further, the part attached to the attachment position of the part may be a nozzle holder for holding the extinguishing nozzle.

  Furthermore, in the present invention, the second invention (the invention according to claim 5 and its dependents) is rotatably attached by a hinge to the outlet of a fire extinguishing hose provided on the front surface of the housing, In a fire hydrant device having a fire hydrant door which is opened and closed by turning a mouth, as a separate body from the fire hydrant door, it is rotatably attached to the outlet by a hinge different from the hinge for attaching the fire hydrant door. A fire extinguisher device characterized in that the fire extinguisher door is further provided with a driven rotating portion provided so as to be driven to rotate as the fire hydrant door rotates. .

  In the second aspect of the invention, the fire hydrant door may be provided with a hook portion which is moved to rotate the driven rotation portion by being driven to rotate in the opening direction. Further, the hook portion may be pulled to rotate the driven portion so as to be delayed when the fire hydrant door rotates in the opening direction. Further, the hinge for attaching the fire hydrant door and the hinge for attaching the driven rotation portion may be damper dampers each having a damper for controlling a rotation operation. Further, the part attached to the attachment position of the part may be a nozzle holder for holding the extinguishing nozzle.

  In this invention, according to the first invention, the center of gravity of the fire hydrant door including the parts to be mounted can be brought close to the hinge by having the mounting position of the parts at the position close to the hinge. . Thereby, the moment when the fire hydrant door rotates can be reduced.

  Further, according to the second aspect of the present invention, the load of the component to be attached can be dispersed to the side of the driven pivoting part by having the attached pivoting part at the mounting position of the component, and the load on the fire hydrant door can be reduced. Can. Thereby, the moment when the fire hydrant door rotates can be reduced.

  Therefore, according to the present invention, the moment of the fire hydrant door can be reduced by any of the first and second inventions.

  Here, in any of the first and second inventions, since the moment of the fire hydrant door can be reduced, the damper for controlling the rotational movement of the fire hydrant door can be sufficiently operated. For example, if the fire hydrant door is of the type that opens downward (forward tilting door), the fire hydrant door can be opened slowly enough, and the fire hydrant door is light enough. It can be closed.

  Furthermore, in the first invention, the hinge for attaching the fire hydrant door is a damper hinge having a damper for controlling the rotation operation, and in the second invention, the hinge for attaching the fire hydrant door and the follower rotation unit By making both of the mounting hinges be damper hinges having dampers that control rotational movement, in any of the inventions, it is possible to eliminate the need for providing a space for housing the dampers in the housing.

In the tunnel.

[Fire hydrant door]
The fire hydrant door 4 is rotatably attached to the outlet 3 by a hinge 5 and opens and closes the outlet 3 by rotating around a rotation shaft 5 a of the hinge 5. In the present embodiment, as the fire hydrant door 4, the lower end of the drawer 3 is pivotable by the hinge 5 having the rotation axis 5 a along the lateral direction (width direction) of the housing 2 when the lower end 4 d is closed. It is attached to the edge 3 b and used a forward tilting door which rotates downward to open the outlet 3. In addition, one having a rotation angle of about 180 degrees when fully open is used. When the fire hydrant door 4 is fully opened, it hangs down substantially from the lower end edge 3b of the outlet 3 and rotates until the back surface 4c substantially faces the front direction.

  Various components are attached to the back surface 4 c of the fire hydrant door 4. In the case of the present embodiment, a lever mechanism portion having a nozzle holder 6b for detachably holding the fire extinguishing nozzle 6a provided at the tip of the fire extinguishing hose 6, and a control lever 7a for opening and closing the fire hydrant valve (not shown). 7 and a latch mechanism 8 having a latch 8a for locking and unlocking the closed state of the fire hydrant door 4 (the operation unit is provided on the door surface side) are attached.

  Then, at least a part of the components attached to the back surface 4c side of the fire hydrant door 4 is a position closer to the hinge 5 (an intermediate position between the end edge 4d on the hinge 5 side and the end edge 4e on the opposite side) Is mounted on the hinge 5 side). In the case of the present embodiment, the nozzle holder 6b is attached at such a position, and the extinguishing nozzle 6a is always attached to the nozzle holder 6b and held.

  According to the fire hydrant device 1-1 of the present embodiment, at least a part of the parts mounted to the fire hydrant door 4 is mounted at a position closer to the hinge 5, the barycentric position of the fire hydrant door 4 including the mounted parts It can be brought close to the hinge 5. Thereby, the moment when the fire hydrant door 4 rotates can be reduced. Therefore, a damper for controlling the rotation operation of the fire hydrant door 4 (details will be described later as being contained in the hinge 5) can be sufficiently operated, and this embodiment uses the fire hydrant door 4 as an anteversion type door In the case of the form, the hydrant door 4 can be opened sufficiently slowly, and the hydrant door 4 can be closed with a sufficiently light force.

  Furthermore, the fire hydrant door 4 in this embodiment is demonstrated in detail.

  Specifically, the fire hydrant door 4 is made of a flat plate made of metal, and has edge portions 4 d, 4 e, 4 f, 4 g formed so as to be bent toward the inside of the door on four sides thereof. . Among these end edges, a lower edge (during closing) end edge 4d located on the hinge 5 side is provided with a projecting edge 4h formed so as to continuously project inward of the door. . Then, while the hinge 5 is attached to the outer surface of the end edge 4d, the nozzle holder 6b holding the extinguishing nozzle 6a on the surface of the inner edge of the projection 4h (the side facing the back surface 4c) It is attached in close proximity, and as described above, the extinguishing nozzle 6a is always detachably attached to and held by the nozzle holder 6b as described above.

  In this embodiment, with this attachment structure, the fire extinguishing nozzle 6 a can always be attached to the fire hydrant door 4 via the nozzle holder 6 b in a state where the fire extinguishing nozzle 6 a is as close as possible to the hinge 5.

  In the present embodiment, the end edge 4d and the projecting edge 4h are continuous and integrated, but may be separate and connected by a fastening member such as a bolt.

  Further, as the end edge 4d is formed so as to be bent approximately 90 degrees with respect to the surface of the fire hydrant door 4 inward of the door, the flange 4h continuously formed on the end edge 4d Is also formed so as to be bent approximately 90 degrees with respect to the door surface, and the surface on which the nozzle holder 6b is attached is positioned approximately 90 degrees with respect to the door surface of the fire hydrant door 4, The surface having the mounting position of the nozzle holder 6b is 90 with respect to the door surface of the fire hydrant door 4 as provided so as to bend the flange portion 4h alone or with the end edge 4d at an angle larger than 90 degrees. It may be located at an angle greater than one degree.

  Here, in the present embodiment, the shape of the left and right end edges 4f and 4g of the fire hydrant door 4 is the side of the end edge 4d whose width (length in the thickness direction of the door) is close to the hinge 5 (rotation (The side of the center of the edge 4e) (the side of displacement of the rotation) further from the opposite hinge 5) (the shape of the edge 4g in FIG. 2). By this shape, the barycentric position of the door itself of the fire hydrant door 4 (a single door excluding attached parts) can be brought close to the hinge 5. That is, also by this shape, the moment of the fire hydrant door 4 can be reduced.

[Nozzle holder]
The nozzle holder 6b is provided with a gripping portion 6c for gripping and holding the fire extinguishing nozzle 6a, and a support portion 6d provided with the gripping portion 6c at its distal end and an attachment portion to the projecting edge 4h on the proximal end side. It consists of In the nozzle holder 6b, the supporting column 6d is provided upright on the surface facing the door back surface 4c of the projecting edge 4h by the attachment section on the base end side, and the gripping unit 6c on the distal end side is It arrange | positions on the door back surface 4c so that it may be located sideways along the width direction of the fire hydrant door 4, and the fire extinguishing nozzle 6a hold | maintained at it may be provided. Although not shown, the attachment portion provided on the support 6 d may be a substantially L-shaped bent portion, and the bent portion may be attached to the projecting edge 4 h by a fastening member such as a bolt. In addition, in the case of this embodiment, although the number of the nozzle holders 6b is two in a row in the width direction of the fire hydrant door 4, the number can be appropriately changed.

[Hinge (for fire hydrant door)]
As shown in FIG. 2, the hinge 5 has two pivotal connection portions 5 b and 5 c that rotate around the rotation shaft 5 a, and one of the pivotal connection portions 5 b is an end edge portion of the fire hydrant door 4. It is connected so as to be a forward tilt type door which is connected to 4 d and the other rotation connection part 5 c is connected to the lower end edge 3 b of the outlet 3 and the fire hydrant door 4 rotates downward to open the outlet 3. It is done. And in this embodiment, the hinge 5 uses the damper hinge which incorporates and has a damper which controls rotation operation of the fire hydrant door 4. By using this damper hinge, it is possible to eliminate the need to provide a space for housing the damper in the housing 2 and to thin the housing 4 while providing a damper for controlling the rotation operation of the fire hydrant door 4 It can be done. In the case of the present embodiment, the number of hinges 5 is two along the width direction of the fire hydrant door 4, but the number can be changed as appropriate.

  Here, the operation at the time of opening and closing of the fire hydrant door 4 in the fire hydrant device 1-1 of the present embodiment will be described.

  FIG. 4 shows the operation at the time of opening and closing the fire hydrant door 4 divided into three stages, where (a) shows the fully closed state, (b) shows the half open state, and (c) shows the fully open state. There is. The extinguishing nozzle 6a held by the nozzle holder 6b is not shown.

  The nozzle holder 6b is displaced as shown in (a) to (c) of the figure when the fire hydrant door 4 is opened and closed, but there is no change in the positional relationship with the hinge 5 at any stage. The fire extinguishing nozzle 6a is attached to such a nozzle holder 6b, and when the fire hydrant door 4 is opened and closed, the fire extinguishing nozzle 6a is maintained at a position close to the hinge 5 at all times and displaced. Thus, when the fire hydrant door 4 is opened and closed, the moment of gravity is reduced since the center of gravity position including the nozzle holder 6 b and the extinguishing nozzle 6 a held by the nozzle holder 6 b is always close to the hinge 5. Moreover, the load of the nozzle holder 6b and the extinguishing nozzle 6a held thereby acts in the direction of closing the fire hydrant door 4 at the position of (a), but the fire hydrant door 4 rotates to the position of (b) It changes so as to act in the direction to open the fire extinguishing smoke door 4 gradually by the way, but the mounting position is provided at the flange 4h, compared with the case where it is attached to the back 4c of the fire hydrant door 4 Because the change is delayed, the moment of the hydrant door 4 is also reduced accordingly. For this reason, compared with the case where the nozzle holder 6b is attached to the back surface 4c of the fire hydrant door 4, the position of the holding part 6c of the nozzle holder 6b is the same, and the position where the fire extinguishing nozzle 6a is held is the same. Even in this case, the moment of the fire hydrant door 4 can be reduced, and the rotational speed of the fire hydrant door 4 can be reduced. The moment of the fire hydrant door 4 is also reduced by shortening the distance between the hinge 5 and the position on the flange 4 h to which the nozzle holder 6 b is attached.

Second Embodiment
Next, a fire hydrant apparatus 1-2 according to a second embodiment will be described with reference to FIGS. 5 to 7. In addition, only the components different from the above-described fire hydrant apparatus 1-1 will be described, and the same components will be denoted by the same reference numerals, and the description thereof will be omitted.

[Following rotation part]
As shown in FIG.5 and FIG.6, the fire hydrant apparatus 1-2 is provided with the driven rotation part 10 as a thing provided with the attachment position of components instead of the flange 4h in the fire hydrant apparatus 1-1. .

  The driven rotation portion 10 is rotatably attached to the outlet 3 by a hinge 11 different from the fire hydrant door hinge 5 as a separate body from the fire hydrant door 4, and the fire hydrant door 4 is It is provided to rotate following the rotation. Then, at least a part of the components attached to the back surface 4 c side of the fire hydrant door 4 is attached to the driven rotation unit 10 instead of the flange 4 h of the fire hydrant device 1-1.

  According to the fire hydrant device 1-2 of the present embodiment, by providing the driven rotation unit 10, the load of the attached component can be dispersed to the driven rotation unit 10 side, and the load of the fire hydrant door 4 can be obtained. It can be made smaller. Thereby, the moment when the fire hydrant door 4 rotates can be reduced.

  In the case of the present embodiment, the driven rotation portion 10 is rotated by the hinge 11 as a standing piece positioned at a position where a part of the projecting edge 4 h inside the door of the fire hydrant door 4 is cut away. It is movably attached to the outlet 3. Then, a nozzle holder 6b for holding the fire extinguishing nozzle 6a is attached to the side of the driven rotary unit 10 close to the hinge 11 on the side facing the back surface 4c of the fire hydrant door 4 similarly to the fire hydrant device 1-1. At all times, the extinguishing nozzle 6a is attached to and held by the nozzle holder 6b.

[Hinge (for driven rotation part)]
The hinge 11 has two pivotal connection parts (not shown) that rotate about a rotational axis located on the same axis as the rotational axis 5a of the hinge 5, and one rotational coupling part is a driven rotational part 10, and the other rotation connection portion is connected to the lower end edge 3b of the outlet 3 so that the driven rotation portion 10 can be rotated in the same direction as the fire extinguisher door 4.

  As the hinge 11, as in the case of the hinge 5, a damper hinge having a built-in damper for controlling the rotational movement of the driven rotation unit 10 is used, and there is no need to provide a space for housing the damper in the housing 2. Is supposed to be able to

[Hanging part]
The fire extinguisher door 4 is provided with a hooking portion 12 which is driven by the rotation in the opening direction to rotate the driven rotating portion 10.

  In the present embodiment, the hooking portion 12 includes a support 12a whose base end is fixed to the back surface (surface opposite to the back surface 4c) of the projecting edge 4h of the fire hydrant door 4 and a distal end of the support 12a. It has a contact portion 12b extending laterally and provided so that the back surface of the driven rotation portion 10 (surface opposite to the side on which the nozzle holder 6b is attached) is positioned in the rotation trajectory, Is substantially L-shaped.

  In the hook portion 12, when the fire hydrant door 4 rotates in the opening direction, the contact portion 12b contacts the back surface of the driven rotating portion 10 from behind, and the driven rotating portion 10 is hooked from behind and rotated forward. Although it operates, in the case of the present embodiment, the contact portion 12b is separated from the back surface of the driven rotation portion 10 when the fire hydrant door 4 is fully closed, during the rotation of the fire hydrant door 4 in the opening direction. The contact portion 12 b is in contact with the back surface of the driven rotation portion 10. That is, when the fire hydrant door 4 is rotated in the opening direction from the fully closed state, it operates so as to rotate the driven rotation unit 10 after the rotation. By changing the angular interval between the contact portion 12b and the back surface of the driven rotary unit 10 when the fire hydrant door 4 is fully closed, the timing at which the driven rotary unit 10 is rotated behind the fire hydrant door 4 can be changed. .

  The hooking portion 12 is not limited to the above-described configuration as long as the hooked portion 12 can be rotated by following the rotation of the fire hydrant door 4 in the opening direction. . That is, as long as the driven rotation unit 10 can be rotated by following the rotation of the fire hydrant door 4 in the opening direction, various configurations can be used.

  Here, the operation at the time of opening the fire hydrant door 4 in the fire hydrant device 1-2 of the present embodiment will be described.

  FIG. 7 shows the operation at the time of opening the fire hydrant door 4 divided into three stages, where (a) shows the fully closed state, (b) shows the half open state, and (c) shows the fully open state. ing. As in FIG. 4, the extinguishing nozzle 6 a held by the nozzle holder 6 b is not shown.

  In the case of the present embodiment, the driven rotation unit 10 is rotated following the rotation of the fire hydrant door 4 in the opening direction. A nozzle holder 6 b for holding the extinguishing nozzle 6 a is attached to the driven rotation unit 10, and the load thereof is dispersed to the driven rotation unit 10 side. Thereby, the moment of the fire hydrant door 4 can be made small. Furthermore, when the fire hydrant door 4 is rotated in the opening direction from the position of (a), only the fire hydrant door 4 is first rotated, but the contact portion 12b of the hook portion 12 is in the middle of the rotation. , And the driven rotation portion 10 is hooked and pulled in the opening direction of the fire hydrant door 4 to be rotated. At that time, the load (the nozzle holder 6b and the driven holder 10b) of the driven rotation unit 10 from the position (b) where the holding portion 6c of the nozzle holder 6b holding the extinguishing nozzle 6a exceeds just above the rotation axis of the hinge 11. The load of the extinguishing nozzle 6a to be held is changed from the side acting to rotate the driven rotation portion 10 in the closing direction of the fire hydrant door 4 to the side acting to rotate in the opening direction. Until there is a change, the load of the driven rotating portion 10 pulled by the hook portion 12 acts to reduce the moment against the rotation of the fire hydrant door 4 in the opening direction. That is, in addition to the fact that the moment of the fire extinguisher door 4 can be reduced by dispersing the loads of the nozzle holder 6b and the extinguishing nozzle 6a to the side of the driven rotating portion 10, the load of the driven rotating portion 10 is a fire hydrant While acting to rotate the driven rotation unit 10 in the closing direction of the door 4, the load of the driven rotation unit 10 can also reduce the moment of the fire hydrant door 4. Then, after the load of the driven rotation unit 10 changes to a side acting to rotate the driven rotation unit 10 in the opening direction of the fire hydrant door 4, the load causes the fire hydrant door to open in the opening direction of the fire hydrant door 4. Following 4 rotation, it rotates to the position of (c). In the case of the present embodiment, when the fire hydrant door 4 is rotated in the opening direction, the load of the driven rotary unit 10 is delayed by rotating the driven rotary unit 10 behind the rotation of the fire hydrant door 4. It is also possible to delay the timing of changing from the side acting to rotate the driven rotating portion 10 in the closing direction of the fire hydrant door 4 to the side acting to rotate in the opening direction, so that the driven rotating portion 10 It is also possible to lengthen the time during which the moment of the fire hydrant door 4 can be made small by the load of.

  As mentioned above, although embodiment of this invention was divided and demonstrated to 1st Embodiment and 2nd Embodiment, this invention is not limited to said embodiment, A various change is possible .

  For example, in any of the embodiments, the fire hydrant door 4 may be rotated about 90 degrees instead of rotating about 180 degrees between the fully closed position and the fully open position. In addition, the fire hydrant door 4 may be a fire hydrant door (a flip-up type door) of a type that opens upward by rotating upward. In that case, when the fireproof door 4 is closed, the upper end edge 4e is rotatably attached to the upper end 3a of the outlet 3 by a hinge member having a rotation axis along the lateral direction (width direction) of the housing 2. Become. Further, the component attached to the position closer to the hinge 5 is not limited to the nozzle holder 6b, and may be, for example, the lever mechanism portion 7, the latch mechanism portion 8 or the like.
