Description

  The present invention relates to a fire hydrant device that is installed in a subway platform or the like and performs fire extinguishing work by pulling out a hose with a nozzle in the event of a fire.

  Conventionally, a stand-type fire hydrant device has been installed at the platform of a subway station. Fire hydrant devices are installed, for example, on the back side of the up line and down line, for example, at the platform between the up line and down line. When this happens, station staff and train crews can use fire hydrants installed at their homes to perform fire fighting activities.

  In this way, the fire hydrant device installed in the subway platform is provided with a fire hydrant door that can be opened and closed on the front side of the metal storage box, and a notification device door provided on the top of the fire hydrant door. A transmitter, a red indicator lamp, an acoustic hole corresponding to a built-in alarm speaker, and an emergency telephone door corresponding to a built-in emergency telephone are provided.

  The red indicator lamp on the reporting device door is always on, so that the location of the fire hydrant device can be seen from a distance. In the event of a fire, when the switch inside the button is turned on by pressing the button provided in the center of the transmitter, a transmission signal is sent to the disaster prevention reception board (fire receiver) in the monitoring room and fires from the notification section of the disaster prevention reception board A warning signal is output, and a district sound signal is sent to a district acoustic terminal connected to a control line drawn from the disaster prevention reception board and installed at each location, and a warning sound is also output at each prescribed location. .

  The fire hydrant device has a fire hydrant valve inside the storage box, a fire hose fitted with a nozzle is connected to the secondary side of the fire hydrant valve, and it is stored in a foldable state by hanging it on the internal holder. Yes.

  Normally, the fire hydrant door of the fire hydrant device is closed and is kept closed by an appropriate door lock mechanism or the like. In the event of a fire, operate the door lock mechanism to release the door closed state and open the fire hydrant door. For example, one person pulls out the fire hose while holding the nozzle and heads for the fire occurrence place (fire extinguishing target) Two or more people perform fire fighting activities, such as another person operating a transmitter to report and opening the hydrant valve. This is to avoid the problem that if the hydrant valve is opened while the hose is being pulled out, the hose may not be pulled out properly due to water pressure and its reaction, or a danger may occur, and the hydrant door must be opened during use. This is because it needs to be maintained by hand.

  Thus, a fire hydrant device that requires at least two-man operation is legally defined as No. 1 fire hydrant, and on the other hand, as a fire hydrant that can be operated by one person, while suppressing the reaction force due to water discharge, The No. 2 fire hydrant used is also legally stipulated.

  However, in such a conventional fire hydrant device, when installed in a subway platform or the like sandwiched between an up line and a down line, for example, when installed with a fire hydrant door facing the up line side, the down line side is a fire hydrant On the other hand, when the fire hydrant door is installed facing the down line side, the up line side is the back side of the fire hydrant apparatus, and the fire hydrant apparatus is separate even though the down home and the up home are adjacent to each other. Need to be installed.

  To solve this problem, install a fire hydrant device in the center of the platform between the up platform and the down platform, and install a fire hydrant door in the longitudinal direction of the platform, not on the track side. It is possible to open fire extinguisher doors of the same hydrant device to enable fire extinguishing activities against fire. However, even in this case, since the front side of the fire hydrant device cannot be seen from the opposite direction of the home which is the back side of the fire hydrant device, there is a problem that is not necessarily appropriate as the installation form of the fire hydrant device.

  In addition, fire hydrant doors provided in conventional fire hydrant devices are often configured to rotate sideways and open, and when starting a water discharge operation, the opened fire hydrant door has an adverse effect on the water discharge operation, such as pinching a hose during water discharge. In order to prevent this from happening, it is necessary for the attendant to keep the hydrant door open. In addition, if the door is kept open, there is a problem that the door blocks a passage on the platform and hinders fire fighting and evacuation.

  The present invention provides a fire hydrant device that allows a hose with a nozzle to be pulled out from both sides of the fire hydrant device, eliminates restrictions on the installation direction in a subway platform, etc., and allows the door to be opened without hindering fire fighting activities or evacuation. For the purpose.

(Basic effect)
The present invention, in a fire hydrant device, a box-shaped device body that is open on both sides, a hose with a nozzle, a hose storage portion that accommodates a hose with a nozzle in the device body so that the hose can be taken out from both openings, Opened on each of the openings on both sides of the main body of the device, the opening is closed by unfolding and holding the screen fixed upward, and the opening of the upper end of the screen is released by folding the screen downward. Since the openable openable and closable screen door is provided, the fire hydrant device has screen doors on both sides, so there is no front and back, and both sides are installed on the operation side, for example, in a subway platform sandwiched between the up and down lines Thus, even with a single fire hydrant device, it can be virtually assumed that one fire hydrant device is installed from both the upstream side and the downstream side. One of the screen doors on both sides of the fire extinguisher body can be fired by opening one of the screen doors and removing the hose with a nozzle as necessary. By installing a fire hydrant device, it can be handled in the same way as two hydrant devices apparently installed.

  In addition, since a screen door with a screen that can be freely opened and closed is provided in each of the openings on both sides of the apparatus main body, the apparatus main body and the screen door are separately manufactured at the assembly manufacturing stage. By assembling and fixing the screen door to each of the openings, the fire hydrant device can be completed, manufacturing assembly is easy, productivity is high, and manufacturing cost can be reduced.

  In addition, when the screen is soiled or damaged after installation, the screen door that is soiled or damaged is removed from the main body of the apparatus and replaced with a separately prepared screen door, so that the screen can be easily and easily repaired.

(Folding inside the bottom of the screen door)
In addition, the screen door is folded to the lower inner side by releasing the holding of the upper end of the screen so that the opening is opened. Therefore, when the screen is released and the door is opened, the screen falls downward. Thus, it is folded inward so that it does not jump out of the fire hydrant device like a conventional side-open fire hydrant door, and does not hinder fire fighting activities and evacuation.

(Effects of screen door structure)
The screen door includes a door frame attached and fixed to the opening of the apparatus main body, a plurality of guide bar members arranged at predetermined intervals between the upper and lower ends of the back surface of the screen, and a guide bar member arranged on the back surface of the screen. Guide the left and right ends of the guide bar member with multiple weight bar members placed between them and the inside of the opening frame on both the left and right sides of the door frame, with the left and right sides of the screen positioned inside the opening frame. A first guide rail that guides and moves in the vertical direction along the groove, and a first guide rail that is disposed inside the first guide rail and that slides on both ends of the weight bar to restrict movement in the depth direction and guide and move in the vertical direction. 2 By holding the guide rail and the guide bar member at the upper end of the screen, the screen is expanded and held in a closed state. And a screen opening / closing mechanism for releasing the holding and folding the screen, the guide bar member is released along the first guide rail by releasing the holding of the guide bar member at the upper end of the screen in the unfolded state of the screen. When the screen is dropped, both end sides of the screen are located inside the opening frame, so the guide bar member falls while curving the screen part in between, which causes the screen to fall inside the bottom of the opening. The screen is folded and opened, and the screen folded portion does not protrude outward at all. Therefore, a fire extinguishing operation such as hose pull-out is not hindered by the screen folded portion and can be easily performed.

  Further, when the holding of the screen is released and the guide bar member is dropped along the first guide rail, an inward bending of the screen portion during the dropping of the guide bar member is provided between the guide bar members. The weight is applied by the weight of the weight bar, and as the guide bar member falls, it is possible to smoothly fold the screen portion in between.

  In addition, the weight bar member is disposed between the plurality of guide bar members disposed on the back surface of the screen, and is applied to the second guide rail so as to restrict the movement in the depth direction at both ends of the weight bar member. By applying tension (weight) to the opened screen by the weight of the weight bar member and regulating the movement of the weight bar in the depth direction, the flatness of the screen in the expanded state is improved, and the conventional metal that opens sideways is used. It is possible to produce the same texture as a fire hydrant door.

(Effects of screen opening / closing mechanism)
In addition, the screen opening / closing mechanism is provided with a buckle bracket (buckle bracket) upward on the guide bar member at the upper end of the screen and a buckle device (buckle device) in the opening frame at the top of the door frame, and the buckle bracket is inserted into the buckle device By holding the screen in the closed state, the buckle device is released by holding the buckle device by a predetermined operation so that the screen is folded and opened. By pulling forward, the holding of the buckle fitting is released and the deployed screen is dropped, and the screen can be opened easily and reliably to perform fire extinguishing activities.

(Distance between guide bar and weight bar)
Further, with respect to the distance (L1) between the weight bar member arranged on the back surface of the screen and the guide bar member arranged adjacent to the upper side thereof, the weight bar member and the guide bar member arranged adjacent to the lower side thereof are arranged. Since the interval (L2) is shortened (L1> L2), the weight bar member is arranged not at the center between the guide bar members but at a position slightly offset to the lower side. When the screen part begins to bend inward, the weight bar member is positioned slightly below the center, so that the weight of the screen is more strongly biased by the weight and the screen can be folded more smoothly. Is possible.

(Effects of upper and lower guide bars)
The plurality of guide bar members disposed on the back surface of the screen are plate-shaped bar members having a rectangular cross section, and the guide bar members disposed at the upper and lower ends of the plurality of guide bar members are provided with rollers provided at both ends. The guide bar member placed between the upper and lower ends is housed in the guide groove of the first guide rail so as not to rotate. The bar rotates inward as the screen falls, making it possible to fold the screen securely inside the door.

  Also, the upper guide bar member has a buckle bracket that is used to open and close the screen, but if it falls due to the release of the screen and is folded inside the lower part of the opening, the upper guide bar member will be on the outside. Rotating and buckling metal fittings are turned sideways, and it is possible to prevent the buckle metal fittings from popping up and obstructing the hose drawer.

(End of weight bar guide rail)
The second guide rail has a guide rail end at a predetermined position between the first weight bar member from the bottom and the second guide bar member from the bottom with the screen opened and the door opening closed. In addition, a curved guide rail extending inwardly from the end of the guide rail is integrally formed, and the both ends of the first weight bar from the bottom located below the end of the guide rail in a state where the screen is opened are opened. Since the overhanging pieces that restrict the movement in the depth direction are provided at both ends of the door frame, the lower side of the second guide bar that guides the movement of the weight bar in the vertical direction terminates in the middle. It is possible to smoothly fold the screen inside.

  In addition, the weight bar member positioned below the guide rail end is in a free state in a state where the screen is flattened, but the movement of the weight bar member in the free state is provided at both inner ends of the door frame. By abutting the projecting piece, it is possible to improve the flatness of the screen in the unfolded state.

  Further, when the screen in the folded state is lifted inside the lower part of the door opening and deployed in a flat closed state, both sides of the weight bar member provided on the screen folded inside the lower part of the door opening are connected to the second guide rail. The guide guide moves along the curved guide rail extending inward from the end to the second guide rail, and the screen in the folded state is smoothly flattened to close the door opening.

(Effect of reporting device door)
In addition, since the screen door is provided with a notification device door provided with at least one of an emergency indicator, a transmitter, a sound device, or an emergency telephone door at the upper part of the door frame, for example, on the up line and down line When installed in a subway platform, it is possible to perform necessary operations from the up line home side and the down line home side by looking at the notification device doors located on each side. By installing one fire hydrant device, it can be handled in the same way as two fire hydrant devices are installed, apparently including the reporting device door.

(Effects of hose compartment)
In addition, since the rectangular frame that holds the left and right ends or the upper and lower ends of the hose that is wound in an annular shape from the outside is disposed in the apparatus main body, the hose storage portion has a screen door disposed on both sides of the apparatus main body. It is possible to open either one and pull out a hose with a nozzle. By installing one fire hydrant device in a subway platform or the like, it is possible to perform a fire extinguishing operation equivalent to installing two fire hydrant devices.

(Effect of fire hydrant valve)
In addition, a fire hydrant valve that can be operated from both sides is provided with the screen doors arranged on both sides open in the equipment body, so either one of the screen doors arranged on both sides of the equipment body is opened and equipped with a nozzle. The fire hydrant valve can be opened and operated while the hose is pulled out, and the fire hydrant valve can be operated from both sides. By installing only one fire hydrant valve, apparently two Fire extinguishing work equivalent to installing a fire hydrant device is possible.

(Effect of double hose)
In addition, since the hose housing part accommodates two sets of hoses with nozzles so that they can be taken out from both sides of the main body of the apparatus, two fire hydrant devices are arranged back to back while being one fire hydrant device. Allows handling equivalent to the case.

In addition, the word “fire hydrant” and a predetermined fire fighting chapter are printed on the front side.

  Between the upper and lower ends of the back surface of the screen 16a, and between them, guide bars 46 are arranged at equal intervals by adhesive fixing or the like, and weight bars 48 are also arranged between the guide bars 46 by adhesive fixing or the like.

  The guide bar 46 and the weight bar 48 function as a framework and a weight to stretch the screen 16a flat in the unfolded state so that the screen 16a is not easily wrinkled.

  The guide bar 46 is a plate-like rod-like member that is flat up and down, and the weight bar 48 is similarly a plate-like rod-like member that is flat up and down. Further, the guide bar 46 and the weight bar 48 hold the screen 16a in their unfolded state by their own weights, and naturally fall with the opening operation to open the door opening 15a with the screen 16a folded to open a sufficient weight. The metal member can be secured.

  The guide bars 46 arranged at the upper and lower ends support rollers 62 at both ends. The rollers 62 enter the guide grooves of the first guide rail 50 shown in FIGS. Is supported rotatably. The guide bar 46 disposed between the upper and lower ends is not provided with rollers at both ends but is directly placed in the guide groove of the first guide rail 50, and the tip is rounded so that it can move smoothly.

Here, as shown in FIG. 5, the weight bar 48 disposed between the guide bars 46 on the back surface of the screen 16a has a center distance L1 between the guide bar 46 adjacent to the upper side and the guide adjacent to the lower side. Assuming the distance L2 between the center of the bar 46,
L1> L2
It arrange | positions so that it may become. In the following description, “interval between centers” is simply referred to as “interval”.

  In other words, the weight bar 48 is not located at the center that is half of the arrangement interval of the guide bars 46, but at a position that is slightly offset from the center.

  In this way, the weight bar 48 between the guide bars 46 is disposed when the screen 16a is moved downward to be opened by arranging the weight bars 48 so as to be offset downward from the center between the guide bars 46. The inward bending of the provided screen portion is urged by the weight of the weight bar 48, causing the screen portion between the guide bars 46 to be distorted and bent during lowering, or the guide bar 46 is inclined It is possible to suppress tilting and worsening movement.

  A buckle fitting 60 is provided at substantially the center of the guide bar 46 disposed at the upper end of the screen 16a. As shown in FIG. 1, the buckle fitting 18 is inserted into and held by the buckle device 18a provided above the door opening 15a. Thus, the screen 16a is supported in the unfolded state, and the door opening is closed.

  When opening the screen 16a, the lever provided on the buckle device 18a is pulled forward to release the holding of the screen 16a by the buckle fitting 60, and the screen 16a is moved along the guide portion together with the guide bar 46 and the weight bar 48. The dropped screen 16a is opened as a folded state inside the lower portion of the door opening 15a.

As shown in FIG. 6, a sheath-like first guide rail 50 having a guide groove 66 opened in the vertical direction is disposed on the back side of the door frame 40 provided on the screen door. The roller 62 pivotally supported is fitted into both ends of the guide bar 46 disposed on the back of the upper end of 16a.

  Following the first guide rail 50, the second guide rail 52 is disposed in the depth direction with a predetermined gap, and the gap with the first guide rail 50 forms a guide groove 68 of the second guide rail 52. ing. The guide groove 68 of the second guide rail 52 includes guide end portions 64 bent inward at both ends of the weight bar 48 disposed on the back surface of the screen 16 a, and guides the weight bar 48 in the vertical direction along the guide groove 68. In addition to the movement, the movement of the weight bar 48 in the depth direction is restricted in the unfolded state of the screen 16a, and the screen 16a can be kept flat.

  Further, both ends of the screen 16a moved up and down by the guide bar 46 and the weight bar 48 are positioned on the back surface of the door frame 40 and do not come out forward. Therefore, when the screen 16a is dropped by operating the buckle device. The screen 16a does not protrude outward from the door opening 15a, and can be reliably folded inside the lower portion of the door opening 15a.

  FIG. 7 is an explanatory view showing a part of the guide structure under the screen door. As shown in FIG. 7, the second guide rail 52 that guides and moves the weight bar 48 is notched obliquely downward at a position just before reaching the lowest weight bar 48 in the unfolded state of the screen 16a. An end 70 is formed, and the curved guide rail 54 extends downward and inward following the guide rail end 70.

  In this way, the lower side of the second guide rail 52 is terminated, and the restriction in the depth direction of the weight bar 48 is released on the lower side thereof, so that the screen 16a that falls due to the operation of the buckle device can be moved below the door opening 15a. Since the screen 16a is folded inward, the screen 16a is not disturbed.

  A guide bar 46 provided at the lower end of the screen 16a rotatably supports a roller 62 pivotally supported at both ends in a guide groove 66 of the first guide rail 50, and the screen 16a is dropped by operating the buckle device. In this case, the guide bar 46 at the lower end is rotated inward by the roller 62, and by this movement, the screen 16a is shaken inward so that the folding of the door opening 15a to the lower inner side can be reliably started.

Further, in the unfolded state of the screen 16a, the lowermost weight bar 48 is positioned on the lower side away from the guide rail terminal 70 and is in a free state in which it moves in the depth direction. The protruding piece 56 is arranged on the inner side, and the guide end portion 64 of the weight bar 48 that is free is brought into contact with the protruding piece 56, thereby restricting the movement of the guide bar 46 in the depth direction and flatness. Is maintained. As the overhanging piece 56, a flexible fiber-containing resin sheet that can be bent vertically and does not move laterally is provided.

  Further, the curved guide rail 54 extending from the terminal end of the second guide rail 52 has a lower inner side in the folded state of the screen 16a when the screen 16a in the folded state is pulled up and closed inside the lower portion of the door opening 15a. When the weight bar 48 positioned at the position is pulled up, it is possible to smoothly enter the guide groove 68 of the second guide rail 52 through the guide rail end point 70 while guiding it against the curved guide rail 54. .

When the holding of the buckle metal fitting 60 is released by operating the lever of the buckle device 18a in this state, the remaining guide bar 46 except for the lower end guide bar 46 is attached to the first guide rail 50 as shown in FIG. The weight bar 48 starts to descend all at once along the guide groove, and the screen 16a begins to descend as a whole.

  At this time, the guide bar 46 at the lower end is stopped without being lowered, so that the portion of the screen 16a between the guide bars 46 begins to bend inward as the guide bar 46 adjacent thereto is lowered. Since the weight bar 48 is disposed in the curved portion of the screen 16a between the guide bars 46, a force to push down the curved portion of the screen 16a is applied by the weight of the weight bar 48, and the entire screen 16a is lowered. wear.

  Further, since the lower end guide bar 46 is rotatably supported by the first guide rail 50 by the roller 62, the lower end guide rail 46 rotates so as to fall inward as the screen 16a is dropped. The portion of the screen 16a between 46 is lowered inward to promote bending.

  Subsequently, as shown in FIG. 8C, when the second guide bar 46 from the bottom comes into contact with the lower end guide bar 46 and stops, the second curved portion is applied to the thin line 16a as the upper guide bar 46 descends. Is formed. Similarly, the third curved portion is formed as shown in FIG. 8D, and finally the screen 16a is folded by overlapping the three curved portions as shown in FIG. 8E.
