Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention comprises a flexible cylindrical side wall and a bottom provided at a lower end thereof.
The present invention relates to a liquid storage container for storing a liquid such as water in a space surrounded by a side wall, a bottom, and the like, and more particularly, to a liquid storage container in which the side wall is kept upright so that it can be used on the ground or the like. It concerns a container.

[0002]

2. Description of the Related Art Conventionally, when it is difficult to extinguish a fire, such as a wildfire or an earthquake fire, a bucket-type fire extinguishing watering device is hung on the body of a transport aircraft such as a helicopter and the like, and is flown to the fire spot. Firefighting activities are often performed by discharging water. The fire-extinguishing water sprinkler includes a container main body including a cylindrical side wall and a bottom provided at a lower end thereof. At the bottom,
An opening for discharge is formed, and a valve for opening and closing the opening is rotatably supported by a shaft.
Some types of fire-extinguishing sprinklers have an inflow opening separately from the discharge opening.

In the above fire extinguisher sprinkler, the side wall is formed of a flexible sheet in consideration of easiness of storage and transportation. The side wall portion is easily deformed even by applying a slight force. The side wall becomes cylindrical when stretched by this deformation, and becomes compact when folded. In addition, the water supply in the fire fighting activity is performed not only during the aerial transportation (hereinafter simply referred to as “transportation”) by a transport aircraft, but also in a state where the water is placed on the ground or the like. The former water supply is performed by immersing a fire extinguisher sprinkler in a lake or the like. The latter is supplied by a fire engine or the like, but in this case, it is necessary to keep the side wall upright. Therefore, conventionally, a dedicated holder provided separately from the container body is used. This holder is attached to the container body only when necessary.

[0004]

However, in the conventional fire extinguisher sprinkler, when water is not supplied on the ground or the like, the holder must be removed from the container body and stored in the storage location. When supplying the water, the holder must be taken out of the storage location and attached to the container body. Therefore, there is a problem that not only the work of attaching and detaching the holder is complicated, but also that the work takes time and the work efficiency is reduced. This problem is not limited to the fire extinguisher sprinkler described above, but similarly occurs in a liquid storage container of a type that is suspended and transported by a transport aircraft.

[0005] Therefore, an object of the present invention is to provide a liquid storage container which can be compacted by folding the side wall portion when not in use, to hold the side wall portion upright in a short time only by performing a simple operation. An object of the present invention is to provide a liquid storage container capable of releasing a state.

[0006]

According to a first aspect of the present invention, there is provided a fuel cell system comprising: an upper support having a holder mounted on an upper frame so as to be tiltable; a lower support having a holder mounted on a bottom so as to be capable of tilting; A bending and stretching connection mechanism for bending and stretching the upper and lower struts, and an extension and holding mechanism that holds the upper and lower struts in a straight line in a substantially vertical direction when used, and releases the holding when not in use. Mechanism.

According to the first aspect, when the liquid storage container is not used, the side wall portion is folded. The container body is lowered,
There is virtually no liquid storage space inside. The upper support and the lower support of the holder are largely bent, and become substantially horizontal in the container body. The components and mechanisms of the holder are not separated and are located in the container body as one assembly, and the liquid storage container is compact as a whole. As one mode of use of the liquid storage container, when the liquid storage container is to be erected on the ground or the like, the upper frame is manually lifted. Along with this, the previously folded side wall portion is extended upward. The upper strut and the lower strut each tilt and stand up. When this state is held by the extension holding mechanism when the upper and lower struts extend linearly in the substantially vertical direction, the side wall portion is kept cylindrical, and a liquid storage space is created inside the container body. in this way,
When using the liquid storage container, there is no need to take out the holder from a predetermined storage location or to attach it to the container body. On the other hand, when the holding of the extended state by the extension holding mechanism is released when the liquid storage container is stored, the upper column and the lower column can be bent. Due to this bending, the distance between the bottom and the upper frame is reduced, and the side wall is folded. As described above, when the liquid storage container is stored, it is not necessary to remove the holder from the container body or to clear the holder at a predetermined storage location.

According to a second aspect of the present invention, in addition to the configuration of the first aspect, the extension holding mechanism covers both the upper column and the lower column to bring both columns into an extended state. A slide member slides between a holding position for holding and a release position for releasing the extended state by covering only one of the upper support and the lower support.

According to the second aspect of the invention, when the holder is used, the slide member covers both the upper column and the lower column in the holding position, and holds the upper and lower columns in an extended state. Therefore, the upper and lower struts will not bend unless a large force enough to deform the slide member is applied. When the holder is not used, the slide member, in the release position, covers only one of the upper column and the lower column, and releases the extended state. There is no force to hold the upper and lower struts in an extended state, and the upper and lower struts can be bent. Switching from the holding position to the release position or vice versa is performed by sliding a slide member.

According to a third aspect of the present invention, in addition to the configuration of the first aspect, an elongated hanging member connected to the upper frame, and an elongated hanging member connecting the bottom portion and the upper frame. The apparatus further includes a connecting member, and a length adjusting mechanism for adjusting the length of at least one of the upper support and the lower support held by the extension holding mechanism.

According to the third aspect of the invention, as one mode of using the liquid storage container, there is a mode in which the liquid storage container is transported by a transport aircraft such as a helicopter. The suspending member and the connecting member suspend the container main body at a position separated downward from the transport aircraft while receiving the load of the liquid applied to the container main body in this use mode. At this time, the holder may be in a bent state or an extended state.

When erecting the liquid storage container on the ground or the like, it is important that the length of the connecting member and the length of the holder are substantially equal. If the lengths are not uniform, the connecting members may become loose even though the upper and lower struts of the holder are extended, or the connecting members may be tightened before the upper and lower struts are in the extended state. However, the upright state of the side wall portion becomes unstable. On the other hand, in the third invention, the length of at least one of the upper support and the lower support changes by operating the length adjusting mechanism. Therefore, the length (length of the holder) of the upper support and the lower support held by the extension holding mechanism can be adjusted to the length of the connecting member. When the length of the holder is substantially equal to the length of the connecting member, the distance between the bottom and the upper frame becomes equal at any point.

According to a fourth aspect of the present invention, in addition to the configuration of the first aspect, the bending and stretching connection mechanism is configured such that at least a part thereof is formed of an elastic body, and the upper and lower parts are fully stretched. A connecting member disposed in both the columns, an upper locking member for locking an upper end of the connecting member to one of the upper column and the upper frame, and a lower column and a lower portion of the lower end of the connecting member; And a lower engaging member for engaging either one of the two.

According to the fourth aspect of the present invention, the connecting members arranged in the upper support and the lower support connect the two supports flexibly. The connecting member is expandable and contractable because at least a part thereof is made of an elastic body. Moreover, the connecting member is always pulled regardless of the bending of the upper and lower columns. Therefore, the connecting member does not rattle in the upper and lower columns.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a fire extinguisher sprinkler 1 as a liquid storage container. The container main body 4 showing the majority of the fire-extinguishing sprinkler 1 includes a side wall 2, a bottom 3, and an upper frame 7. In FIG. 1, the side wall portion 2 is indicated by a two-dot chain line in order to make the internal structure of the container body 4 easy to understand. The side wall portion 2 is formed in a tubular shape from a sheet (canvas) made of synthetic resin having flexibility and waterproofness. The bottom 3 is made of a light and high-strength material, for example, a plywood or a synthetic resin whose surface is waterproofed, and is formed in a substantially disc shape, and is attached to the lower end of the side wall 2. The bottom 3 may have a shape other than a substantially disk shape, for example, an elliptical plate shape or a polygonal plate shape. The lower end of the side wall 2 is
It is sandwiched between the bottom 3 and the elastic annular shock absorbing member 5 so as not to fall off. The substantially cylindrical space surrounded by the side wall 2 and the bottom 3 is a storage space 6 for storing water as a liquid. The upper frame 7 is attached along the upper end of the side wall 2. More specifically, a plurality of holes (not shown) are formed in the upper end portion of the side wall portion 2 at substantially equal angles, and the upper frame 7 is passed through these holes. The upper frame 7 is formed by bending a light and highly rigid material, for example, a metal pipe in an annular shape.

The bottom 3 and the upper frame 7 are connected by a plurality (for example, four) of cloth belts 8 serving as connecting members. These belts 8 are arranged at substantially equal angles to each other near the inside of the side wall 2. In addition,
The connecting member may be a belt made of a material other than cloth, or may be a wire such as a wire or a rope.
A plurality of suspension belts 9 as long suspension members are connected to the upper frame 7. The suspending member may be a wire such as a wire or a rope other than the belt. From the viewpoint of suspending the container body 4 in a stable posture, it is preferable to use an even number of suspension belts 9. Furthermore, it is preferable that these suspension belts 9 are divided into several sets P. For example, in the case of four as shown in FIG.
It is said. The hanging belts 9 of each set P are bundled (bundled) at the upper end thereof and are locked by a common auxiliary hook 11. Both sub hooks 11 are locked to a common main hook 12. Main hook 12
Is a fire extinguisher sprinkler 1 by a transport aircraft such as a helicopter
It is to be hooked on the fuselage of the aircraft during transportation.

An angle holding mechanism A for holding the hanging belts 9 of both sets P in a state of being spread at a predetermined angle is provided in the vicinity of the lower portion of the sub hook fitting 11. The angle holding mechanism A contacts the holding member 13 interposed between the upper ends of the hanging belts 9 of both sets P and the upper end of the hanging belts 9 of each set P on the outer surface of the holding member 13. And a fastener 14 for keeping the state. Here, the holding member 13 is formed by dividing a donut-shaped member into two, but the holding member 13 is not limited to this, and a member having a different shape may be used.

As shown in FIG. 1, the bottom 3 is provided with an opening 10 functioning as an inlet and an outlet for water, and a valve 15 for opening and closing the opening. Valve 15 is
It is rotatably supported on the bottom 3 by a support shaft (not shown). A stopper 16 is provided at the center of the bottom 3. The stopper 16 is used to close the opening 10
5 is for abutting against the valve 15 when it is in a horizontal state to restrict further rotation. A lever 17 is fixed to the valve 15, and an operation cable 18 is connected to an end thereof. The operation cable 18 is used to remotely open and close the valve 15 in the transport aircraft. Further, a seal member 19 made of an elastic material such as rubber is attached between the opening 10 and each valve 15 to prevent water leakage. In the drawing, a planar square opening 10 and a pair of planar rectangular valves 15 are shown as an example, but their shapes, numbers, and the like can be appropriately changed. When the number of openings and valves is increased, those openings and valves may be provided at locations separated from each other on the bottom portion 3. It may be opened and closed by a sub-valve forming a part.

A plurality of holders 21 are provided between the bottom 3 and the upper frame 7 to keep the container body 4 in an upright state. Here, the number of the holders 21 is two, but may be three or more. The two holders 21 are located between the adjacent belts 8 and opposed to each other with the axis L1 of the side wall 2 therebetween. Each holder 21 is shown in FIG.
As shown in (a) and (b), an upper strut 22, a lower strut 23, a bending / stretching connection mechanism B and an extension holding mechanism C are provided as main parts. Hereinafter, these will be described.

[Upper column 22 and lower column 23] The upper frame 7 is provided with an upper projection projecting downward, and the bottom 3 is provided with a lower projection projecting upward. The upper projection is constituted by an annular head 24a of an eyebolt 24 that is inserted and fixed to the upper frame 7 from below,
The lower projection is constituted by the annular head 25a of the eyebolt 25 which is inserted and fixed to the bottom 3 from above, but these are merely examples and can be changed as appropriate. The upper support 22 is tiltably covered at its upper end on the head 24a. The lower support 23 is made of a round pipe, and is tiltably covered at its lower end on the head 25a. Regarding both the upper support 22 and the lower support 23,
Nothing is specifically provided to limit the tilt direction. Therefore, unlike the case where the upper and lower columns 22 and 23 are supported by a shaft or the like, the columns 22 and 23 can tilt in multiple directions.

[Extension Holding Mechanism C] The extension holding mechanism C holds the upper support 22 and the lower support 23 in a straightened state (hereinafter referred to as an “extended state”) when the holder 21 is used. This is for releasing the holding during use. The extension holding mechanism C includes a tubular slide member 26 that slides between a holding position and a release position. The slide member 26 is formed of a material having a large specific gravity, for example, a metal material such as stainless steel. Here, the holding position is, as shown in FIG.
This is a position where both struts 22 and 23 are held in an extended state by covering both struts 2 and lower strut 23.
As shown in FIG. 9, the release position is a position where the extended state is released by covering only one of the upper support 22 and the lower support 23 (the upper support 22 in this case), and is located above the holding position. An upper stopper for preventing the slide member 26 from sliding above the release position, and an upper stopper for preventing the slide member 26 from sliding below the holding position are provided on the upper and lower columns 22 and 23. A lower stopper is provided. The upper stopper is constituted by a head 27a of a bolt 27 inserted and fixed to the upper column 22 (see FIGS. 8 and 9), and the lower stopper is constituted by a head 28a of a screw 28 fastened to the lower column 23. However, these are only examples and can be changed as appropriate.

[Bending / stretching connection mechanism B] The bending / stretching connection mechanism B is a mechanism for connecting the upper and lower columns 22 and 23 so as to be able to bend and stretch, and as shown in FIGS. A connecting member 31 is provided. As the connecting member 31, any one of the following three forms can be adopted. A first mode in which the entirety of the connecting member 31 is formed only of an elastic body such as a spring or a rubber string, and a second mode in which the entirety of the connecting member 31 is formed only of an inelastic body such as a chain, a wire, or a string And a third embodiment in which the connecting member 31 is formed by both an elastic body and an inelastic body. In the third embodiment, the elastic body and the non-elastic body are arranged vertically one above the other, but either member may be arranged above (or below). In order to prevent rattling (this point will be described later), the connecting member 31 must be at least partially formed of an elastic body, that is, in the second and third forms. Is desirable. In the present embodiment, a combination of a coil spring 32 as an elastic body and a chain 33 as an inelastic body,
Is used as the connecting member 31. The coil spring 32 is disposed in a tensioned state in the upper column 22,
The chain 33 is arranged so as to be stretched over the entire lower support 23 and the lower end of the upper support 22. The chain 33 is formed in an annular shape, and is hooked on the lower end of the coil spring 32 at both ends.

The upper end of the connecting member 31 is locked to the upper column 22 by an upper locking member, and the lower end is locked to the bottom 3 by a lower locking member. In this embodiment, a shaft portion 27b of the bolt 27 is used as an upper locking member.
The upper end of the coil spring 32 is hooked here. As the lower locking member, the head 25 of the eyebolt 25 described above is used.
a is used, and the chain 33 is passed therethrough. Therefore, the coil spring 32 is located in the connecting member 31 not only at the lower end portion where the lower column 23 is supported, but also at a position upwardly away from the bent portions of the upper and lower columns 22 and 23 (upper end portion of the lower column 23). It is located in.

As described above, the upper and lower columns 22, 23 which are flexibly connected by the flexion / extension connection mechanism B,
The gap between the upper and lower columns 22 and 23 expands or narrows according to the degree of the bending. This gap is formed when the upper and lower columns 22, 23 are extended in a straight line (FIG. 3).
(See FIG. 9 (b)) and spreads according to bending (see FIG. 9). The upper end of the connecting member 31 is
Alternatively, the lower end may be locked to the lower support 23 instead of the bottom 3.

When the slide member 26 is operated by hand, the worker's arm is moved through the upper frame 7 to the storage space 6.
Inside. At this time, it is important that any worker can slide the slide member 26 without difficulty. That is, the slide member 26 is connected to the upper frame 7.
It is important that when the user slides to the holding position, which is the farthest position from the user, the hand of the worker can be reliably reached without taking an unreasonable posture. For this purpose, the holding position is set at a position near the upper frame 7 between the upper and lower columns 22 and 23 in the extended state. This portion corresponds to, for example, a portion separated from the upper frame 7 by about 30 to 40 cm (?) Downward. With the setting of the holding position, the bent portions of the upper and lower struts 22 and 23 are also set at positions closer to the upper frame 7.
2 is set short.

The holder 21 has a length adjusting mechanism D, a shielding mechanism E, an auxiliary connecting mechanism F, a guide mechanism G, and the like, in addition to the above-described configuration. Hereinafter, each of the mechanisms D to G will be described. These mechanisms D to G can be omitted as appropriate.

[Length Adjusting Mechanism D] The length adjusting mechanism D adjusts the length of at least one of the upper and lower columns 22 and 23 held by the extension holding mechanism C, and reduces the length of the holder 21. This is for equalizing the length of the belt 8.
The mechanism D is provided because the length of the holder 21 and the belt 8
This is to avoid the following problem that occurs when the length is not uniform. The problem is that when the fire extinguisher sprinkler 1 is used on the ground or the like, the belt 8 is loosened even though the upper and lower struts 22 and 23 of the holder 21 are in an extended state, or the upper and lower struts 22 are not used. , 23 are stretched before the belt 23 is in the extended state, and the upright state of the container body 4 becomes unstable. As shown in FIGS. 3A and 4, in order to establish the length adjustment mechanism D, the upper column 22 is divided into an upper tube 34 located on the upper side and an outer tube 35 located on the lower side. ing. Inner tube 34 and outer tube 35
Consist of round pipes. The upper end of the inner tube 34 is covered on the head 24a of the eyebolt 24. The inner pipe 34 is provided with a pair of first adjustment holes 36. The first adjustment holes 36 are opposed to each other with the axis L2 of the inner tube 34 interposed therebetween. Note that a plurality of sets of the first adjustment holes 36 may be provided.

The outer tube 35 has substantially the same outer diameter as the lower support 23, and is slidably mounted on the inner tube 34 and rotatable in the circumferential direction. The aforementioned bolt 27 is attached to the outer tube 35. The outer tube 35 is provided with a plurality of sets of second adjusting holes 37, each of which is a set of two, the axis L3 of the outer tube 35.
It is opened in a row along. The same set of second adjustment holes 37 are opposed to each other across the axis L3. The interval d2 between two adjacent second adjustment holes 37 is the same (for example, 10 mm) at any location. In the outer tube 35, a plurality of sets of third adjustment holes 38, which are a set of two, are formed in a row along the axis L3 at a location different from the row of the second adjustment holes 37. ing. The third adjustment holes 38 of the same set are opposed to each other with the axis L3 interposed therebetween. Here, as the location, a location that is shifted by about 90 degrees in the circumferential direction of the outer tube 35 with respect to the row of the second adjustment holes 37 is set, but is not limited thereto. The third adjustment holes 38 of each set are located at positions shifted from the second adjustment holes 37 in the direction along the axis L3. The distance d3 between the adjacent two sets of third adjustment holes 38 is the same (for example, 10 mm) at any point, and is the same as the distance d2 between the second adjustment holes 37.
The third adjustment holes 38 of each set are connected to the adjacent second adjustment holes 3.
It is located in the middle between seven. Therefore, the second adjustment holes 37 and the third adjustment holes 38 are alternately present in the direction along the axis L3. By using these adjusting holes 37 and 38 together, the minimum unit for which the length can be adjusted is shortened (5 mm).

The inner and outer pipes 34 and 35 are provided with either set of the second adjustment hole 37 (or the third adjustment hole 38) and the first adjustment hole 3
6, the positioning pin 39 is inserted. Any positioning pin 39 may be used as long as it can be inserted into and extracted from the first adjusting hole 36 and the second adjusting hole 37 (or the third adjusting hole 38). Can be used. At the end of the positioning pin 39 projecting from the outer tube 35 by insertion, a drop-off preventing member 41 is detachably locked. The falling-off prevention member 41 is for preventing the positioning pin 39 from falling off from the outer tube 35, and for example, a pine needle pin can be used. Further, a flexible tubular covering member 42 is covered on the outside of the outer tube 35, and the covering member 42 covers the positioning pin 39 and the falling-off prevention member 41.

The inner tube 34, the outer tube 35, the positioning pin 39, the falling-off preventing member 41 and the covering member 42 constitute a length adjusting mechanism D. It is preferable that the length adjustment of the holder 21 using the length adjustment mechanism D is performed at the time of manufacturing the fire-extinguishing sprinkler 1. In addition, the length adjustment mechanism D
Instead of the upper support 22, it may be provided on the lower support 23, or may be provided on each of the upper support 22 and the lower support 23. Further, the first adjusting hole 36 may be provided in the outer tube 35 instead of the inner tube 34, and the second adjusting hole 37 and the third adjusting hole 38 may be provided in the inner tube 34 instead of the outer tube 35.

[Shielding Mechanism E] The shielding mechanism E
To cover the end of the. FIG. 3 (a),
As shown in (b), an upper cover 43 is attached to a position where the upper column 22 supports the upper frame 7.
More specifically, a washer 44 is interposed between the inner tube 34 and the upper frame 7. The upper cover 43 is formed in a bellows shape using an opaque and elastic material, for example, rubber, and is covered on the outer side of the upper end of the inner tube 34. The upper end of the upper cover 43 is locked by a washer 44. Similarly, an intermediate cover 45 having the same configuration as the upper cover 43 is mounted on the outer side of the lower support 23 so as to be slidable in the up-down direction. The upper end of the intermediate cover 45 is placed over the lower end of the slide member 26 and is fixed by fixing means such as an adhesive. Although not shown in the drawing, a cover similar to the above may be attached to a supporting portion of the lower support 23 with respect to the bottom 3. In this case, the cover is placed over the lower end of the lower support 23 and the lower support 23 and the bottom 3
The lower end of the cover may be locked to this washer 46 by using a washer 46 interposed between the washer 46 and the cover. The cover 43, 45 attached as described above constitutes the shielding mechanism E.

[Auxiliary Connection Mechanism F] As shown in FIGS. 3A and 6, an auxiliary connection member 47 having the same configuration as the above-described connection member 31 is disposed in the inner tube 34. The point that any of the three forms may be adopted as the auxiliary connecting member 47 is the same as that of the connecting member 31. In the present embodiment, a combination of a coil spring 48 as an elastic body and a chain 49 as an inelastic body is used as the auxiliary connecting member 4.
7 is used. The auxiliary connecting member 47 is disposed in the upper support 23 in a state where the auxiliary connecting member 47 is entirely pulled. The chain 49 is passed through the head 24 a of the eyebolt 24, and the upper end of the coil spring 48 is locked to the end of the chain 49. Therefore, the coil spring 48
In the auxiliary connecting member 47, the auxiliary connecting member 47 is located at a position separated downward from the upper end portion, which is a supporting position of the upper support 22. The lower end of the coil spring 48 is connected to the bolt 5 fastened to the inner pipe 34.
It is hooked on 2. The auxiliary connection member F, the eye bolt 24 and the bolt 52 constitute an auxiliary connection mechanism F.

[Guide Mechanism G] The guide mechanism G is for guiding the upper and lower columns 22, 23 to be in an extended state prior to the holding by the extension holding mechanism C, and the bending of both columns 22, 23. It is provided in the place. As shown in FIGS. 8 and 9, the guide mechanism G has a lower end 35 a of the outer tube 35 functioning as a guide recess, and a guide that projects slightly upward from the upper end opening of the lower support 23 and can fit into the guide recess. The projection 51 is provided. Guide projection 51
For example, a cylindrical member made of a synthetic resin or the like can be used. In this case, it is desirable that the member be inserted into the upper end opening of the lower support 23 and fixed by means such as an adhesive. Note that the positional relationship between the guide recess and the guide protrusion may be reversed, the lower support 23 may be provided with a guide recess, and the upper support 22 may be provided with a guide protrusion.

The fire extinguisher sprinkler 1 of the present embodiment having the above-described configuration is stored and deployed at a base, a water source, a mountain hut, or the like of a transport aircraft when not in use. In this state, FIG.
As shown in (1), the container body 4 is placed on the ground or the like, and the suspension belt 9 is loosened. The side wall portion 2 is folded down and becomes low (flat state), and the water storage space 6 is substantially eliminated inside. The upper support 22 and the lower support 23 of each holder 21 are largely bent, are substantially horizontal in the container main body 4, and do not protrude from the flattened container main body 4. Thus, the entire fire extinguisher sprinkler 1 is compact.

The inner tube 34 of the upper column 22 is connected to the upper frame 7.
, But does not fall off from the eyebolt 24. This is because, as shown in FIG. 6, the auxiliary connecting member 47 arranged in the upper support 22 is
4, the movement of the upper column 22 is restricted by the auxiliary connecting member 47, and the inner tube 34 is pulled toward the eyebolt 24 by the coil spring 48. Similarly, the lower support 23 is largely inclined with respect to the bottom 3, but does not fall off from the eyebolt 25. This is because, as shown in FIG. 7, the connecting member 31 arranged in the lower support 23 is locked to the eyebolt 25, and the movement of the lower support 23 is restricted by the connecting member 31. The support 23 is a coil spring 32
This is because it is pulled toward the bottom 3 side. As shown in FIG. 9, the slide member 26 of each extension holding mechanism C is retracted to the release position of the upper support 22. The tensile force applied to the coil springs 32 and 48 in each holder 21 is the maximum,
Both the connecting member 31 and the auxiliary connecting member 47 are the longest.

The upper column 22 is greatly inclined, and the gap between the upper end thereof and the upper frame 7 is large. The gap is covered by the upper cover 43 which is elastically deformed following the inclination. Similarly, the gap between the upper and lower columns 22 and 23 is large, but the gap is covered by the intermediate cover 45 elastically deformed following the bending.
For this reason, the internal structure of the end of the holder 21 is not exposed, and the appearance does not deteriorate. The two covers 43 and 45 also prevent other parts and members from getting into the gap. In this embodiment, the lower end of the lower support 23 is not covered with a cover, but this portion is hidden by the folded side wall 2 when the fire extinguisher and sprinkler 1 is not used.
There is no danger of exposure and bad appearance.

When transporting the fire extinguisher / sprinkler 1, the main hook 12 shown in FIG. 5 is hooked on a cargo hook or the like of a transport aircraft, and the operation cable 18 is pulled into the cabin. When the transport aircraft takes off, the container body 4 is suspended by the suspension belt 9.
Is suspended. In this state, the fire-extinguishing sprinkler 1 is transported to a location where water is stored, for example, a reservoir, a lake, a marsh, or the sea. At this time, each holder 21 extends to some extent, but does not necessarily have to be linear.

When the vehicle reaches the destination, the transport aircraft is lowered, and the container body 4 is caused to land on a lake or the like from the bottom 3. Then, the suspension belt 9 is loosened, and an upward force of water acts on the valve 15, the bottom 3 and the like. With this force, both valves 15 rotate naturally, and the opening 10 is opened. Water flows into the storage space 6 through the opening 10,
The container body 4 sinks. When the transport aircraft is lifted when the container body 4 is filled with water, the suspension belt 9,
The belt 8 is tightened in order, and the container body 4 is pulled up. In the process of ascending the container body 4, both valves 15 are rotated by the downward force of the water acting on both the valves 15 and the bottom 3, and are brought into a substantially horizontal state. When the container body 4 rises from the surface of the water, the opening 10 is closed and the discharge of water becomes impossible. For this reason, it is possible to transport the container body 4 storing the water to a fire spot in a suspended state. In this transportation, the load of water applied to the container body 4 is received by the belt 8 and the suspension belt 9.

When the container body 4 is lifted, the bottom 3
, A water load is applied to the belt, and the belt 8 is tensioned. Along with this, the upper and lower columns 22, 23 of the holders 21 that have been bent up to that point tend to be automatically extended. This phenomenon occurs as follows. Based on the tensile force acting on the connecting member 31 when the upper and lower struts 22 and 23 are linearly extended, when the upper and lower struts 22 and 23 are bent, the above-described reference is applied to the connecting member 31. A tensile force greater than the tensile force acts. At the time of bending, a gap is formed between the upper support 22 and the lower support 23, and the holder 21 becomes longer by that amount. As described above, when the pulling force increases due to the bending of the upper and lower columns 22, 23, the force (elastic restoring force) against it also increases. The elastic restoring force tends to straightly extend the upper and lower columns 22 and 23 in the bent state. This phenomenon is the same for the auxiliary connecting member 47 which is arranged in the upper support 22 in a state of being pulled. Therefore, in the process of lifting the upper frame 7 and lifting the container body 4, the upper and lower supporting columns 2
2 and 23 automatically attempt to straighten.

As the upper and lower columns 22, 23 in the bent state extend, the angle between them becomes narrower, as shown in FIG. Accordingly, the lower end 35a of the outer tube 35
And the guide projection 51 approach each other. When the lower end 35a slightly covers the guide protrusion 51, the guide protrusion 51
Guides the lower end 35 a into the guide projection 51 while the outer tube 35 and the lower support 23 are standing. As shown in FIG. 8, when the lower end 35a is fitted to the guide projection 51, the axis L3 of the outer tube 35 matches the axis L2 of the lower support 23, and the lower end opening of the outer tube 35 and the upper end opening of the lower support 23. And fits perfectly. There is no step between the outer peripheral surface of the outer tube 35 and the outer peripheral surface of the lower support 23. The slide member 26, which has been at the release position, falls (slides downward) by its own weight, and covers both the upper support 22 and the lower support 23. This slide member 26
As a result, the upper and lower columns 22, 23 are held in the extended state, so that the upper and lower columns 22, 23 are not bent unless a large force enough to deform the slide member 26 is applied. The drop stops when the slide member 26 hits the head 28a of the screw 28, as shown in FIG.

As described above, even when the container body 4 with the side wall 2 folded is suspended from the transport aircraft,
Once the water is pumped, the belt 8 is stretched by its weight, and the holding members 21 are also pulled straight, the slide member 26 is lowered, and the upper and lower columns 22, 23 are held in the expanded state. Therefore, in this case, the slide member 2
Even without performing the operation of 6, the container main body 4 can be prepared for standing use on the ground or the like. To drop the slide member 26 by its own weight, as described above, the axis L2,
It is important to match L3, but the guide mechanism G plays a large role in such matching. Without the mechanism G, when the container body 4 containing water is suspended, the upper and lower columns 22 and 23 may extend substantially in an extended state, but their axes L2 and L3 do not always match. It is not limited.

At the time of the transportation, the belt 8
May be extended, but in this case, each holder 21 also extends. This is because each of the holders 21 is divided into an upper column 22 and a lower column 23 so as to extend vertically. More specifically, the upper and lower columns 22 and 23 are merely connected via a connecting member 31, and the connecting member 31 includes a coil spring 32.
Therefore, as long as the coil spring 32 is elastically deformed and extended.
The upper and lower struts 22, 23 can be extended. Therefore, even if the belt 8 is stretched, the holder 21 is set to be approximately the same length as the belt 8,
The container body 4 containing water can be transported in a stable posture. When the transport aircraft reaches the fire site, the operation cable 18 is pulled from inside the aircraft. Then, each valve 15 rotates and the opening 10 is opened, and water falls through the opening 10 to extinguish the fire. The amount of water released can be adjusted by adjusting the degree of pulling of the operation cable 18 and changing the rotation angle of the valve 15.

Water can be supplied to the container body 4 not only when the container body 4 is carried by a transport aircraft, but also when the container body 4 is placed on the ground or the like.
For example, when there is no lake or the like nearby, water is supplied by a fire engine or the like. In this case, the container main body 4 is set up as follows. As shown in FIG.
Is placed on the ground or the like, and with the suspension belt 9 loosened, the upper frame 7 is gripped by hand or the like and lifted while rotating. The rotation direction at this time is a direction (a direction indicated by an arrow X in FIG. 2) from a position where the upper support 22 supports the upper frame 7 to a position where the lower support 23 supports the bottom 3. With the lifting, the folded side wall portion 2 is extended upward, and finally becomes a substantially cylindrical shape as shown in FIG. The slide member 26 covers only the outer tube 35 in the release position, and
2, 23 are bendable. As the upper frame 7 is lifted, the upper and lower columns 22, 23 of each holder 21 are tilted and rise up. At this time, as described above, due to the elastic restoring force of the coil springs 32 and 48, the upper and lower columns 22 and 23 are exerted with a force to be extended. Therefore, the upper and lower struts 2 can be used without any special operation.
2, 23 stand up automatically.

During the tilting process, the lower end 35 of the outer tube 35
a is fitted to the guide projection 51. When the upper column 22 is completely fitted into the guide projection 51, the upper and lower columns 22 and 23 extend substantially straight in a substantially vertical direction as shown in FIG.
2 and L3 coincide, the lower end opening of the outer tube 35 and the lower support 23
The upper end of the opening fits snugly. The slide member 26 is gripped and slid downward until it stops against the screw 28. The slide member 26 includes the upper support 22 and the lower support 23.
And hold them in an extended state. In this state, the side wall portion 2 is kept cylindrical, and a water storage space 6 is formed inside. Unless a large force is applied to deform the slide member 26, the upper and lower columns 22, 23
Does not bend. Since the upper and lower columns 22 and 23 are in contact with each other, the holder 21 is not further shortened.

Here, the upper frame 7 and the bottom 3 are attached to the upper and lower ends of the side wall 2, and the belt 8 and the holder 21 are interposed at a plurality of places between them. The upper support 22 and the lower support 23 for any holder 21.
Are held in an extended state and do not bend. The lengths of the belt 8 and the holder 21 are uniform. Further, the side wall portion 2 is extended in a substantially cylindrical shape by the holder 21. Therefore, the upper frame 7 is hardly inclined even when an external force is applied to the fire-extinguishing sprinkler 1 by the cooperative action of the belt 8, the holder 21 and the side wall 2, and the side wall 2 is held in a predetermined substantially cylindrical shape. to continue.

In particular, in the present embodiment, the two holders 21 are located at positions facing each other with the axis L1 of the side wall 2 interposed therebetween. For this reason, the upper frame 7 is supported at two points from below by the holders 21 located at positions farthest from each other. At this time, since the upper frame 7 is connected to the bottom 3 via the side wall 2, even if a force is applied to the upper frame 7 from any direction (upper, lower, lateral, etc.), the force is applied to the side wall 2. Received by part 2. As long as the side wall portion 2 does not expand and contract significantly, the container body 4 does not deform.
Even with a small number of holders 21 such as two, the side wall portion 2 can be reliably held in the upright state in a stable state. In this way, the container body 4 is self-supporting and maintains a substantially cylindrical shape despite the fact that the suspension belt 9 is not tensioned.
Water can be injected from the upper part (upper frame 7) of the container body 4 by a fire engine or the like. The container body 4 does not fall down or deform during water injection or storage.

When the container body 4 is filled with water, a suspension belt 9 is connected to a cargo hook or the like of a transport aircraft. When the transport aircraft is lifted with the operation cable 18 loosened, the suspension belt 9 is tensioned and the bottom 3 and the side wall 2 are attached to the transport aircraft in the same manner as in the above-mentioned water supply work in a lake or the like. Hanged. The fire extinguisher sprinkler 1 can be transported to a fire spot by a transport aircraft.

When the fire extinguishing sprinkler 1 is to be stored after the fire extinguishing work, the fire extinguishing sprinkler 1 is placed on the ground, etc.
And the slide member 2 with the operation cable 18 loosened.
Slide 6 from the holding position to the release position. Then
The slide member 26 is in a state of covering only the upper support 22. There is no force to hold the upper and lower struts 22, 23 in the extended state, and these can be bent. There is no support for the upper frame 7 from below,
The side wall 2 can be deformed. Then, several people (for example, 2
The upper frame 7 is moved closer to the bottom 3 while being gripped and rotated by a worker. The rotation direction at this time may be the above-described arrow X direction or the opposite direction.
By the rotation, each holder 21 is bent in a substantially U-shape in a plane, and the side wall 2 is twisted. Approximately 9 upper frames
When rotated by 0 degrees, the side wall 2 is regularly and finely folded like an aperture of a camera as shown in FIG. The bent portions of the holders 21 are located at positions facing each other with the axis L1 of the side wall portion 2 interposed therebetween, and the holders 21 do not come into contact with each other and interfere with each other. These effects can be obtained only by the upper support 2
This is because the support structure of the lower support 2 and the lower support 23 is devised so that these supports 22 and 23 can be tilted in multiple directions.

As described above, according to the present embodiment, unlike the prior art using a dedicated holder separate from the container body,
By lifting the upper frame 7 to extend the upper and lower columns 22 and 23 and sliding the slide member 26,
The side wall portion 2 can be raised or folded in a short time, and the working efficiency can be improved. In addition, since the components of the holder 21 are attached to the container body 4, there is no need to separately take out the components from a predetermined storage location or clear them at the same location. Furthermore, there is no need to attach or remove parts to or from the container body 4, and there is no risk of losing these parts.

By the way, the belt 8 is extended by repeated use, and becomes longer than the holder 21.
The belt 8 may be loosened even though the upper and lower columns 22, 23 are in the extended state. At this time, by operating the length adjusting mechanism D as described below, each holder 21 is lengthened to have substantially the same length as the belt 8. The covering member 42 placed on the outside of the outer tube 35 is moved and shifted from the positioning pin 39 and the drop-off preventing member 41,
Expose these. The stopper member 41 is removed from the positioning pin 39, and the positioning pin 3 is removed from the inner and outer tubes 34 and 35.
Extract 9 Then, since there is no connection between the inner and outer pipes 34 and 35, they can be slid and rotated.

Until the belt 8 is stretched, the inner and outer tubes 34, 3
5 and the second adjustment hole 37 closest to the first adjustment hole 36.
Alternatively, the nearest third adjustment hole 38 is matched. Whether the adjustment hole corresponding to the first adjustment hole 36 becomes the second adjustment hole 37 or the third adjustment hole 38 depends on the elongation of the belt 8 or the like. Adjustment hole 37,
38 can be easily matched with the first adjustment hole 36. At this time, it is not necessary to remove the outer tube 35 from the inner tube 34, and the length adjustment can be easily performed. And the first
Adjustment hole 36 and second adjustment hole 37 (or third adjustment hole 38)
The positioning pin 39 is inserted through the inner tube 34 and the outer tube 35 through the through hole.

Here, since the adjusting holes 37 and 38 are respectively formed along the axis L3 of the outer tube 35, when the adjusting holes 37 and 38 into which the positioning pins 39 are inserted are changed, the above-mentioned upper support column is changed. 22, the length of the holder 21
Length is different. The minimum unit that can be adjusted is determined by the distance between the second adjustment hole 37 and the third adjustment hole 38 adjacent to the second adjustment hole 37. In the present embodiment, (1/2) d2 = 5 mm.
This minimum unit is shorter than the case where there is no third adjustment hole 38 and the interval between adjacent second adjustment holes 37 is the minimum unit.
Therefore, each holder 21 can be made closer to the length of the belt 8 by finely adjusting the length. In addition, as a method of shortening the minimum unit, it is conceivable to provide the third adjustment holes 38 in the same row as the second adjustment holes 37 and narrow the interval between the adjacent adjustment holes 37, 38. There is a possibility that the strength of the tube 35 is reduced. In the present embodiment, the third adjustment hole 38
Are provided at locations different from the rows of the second adjustment holes 37 (locations shifted by about 90 degrees in phase). For this reason, the interval between the adjacent adjustment holes 37 and 38 is widened, and a decrease in the strength of the outer tube 35 can be minimized.

When the positioning pin 39 is inserted, the inner and outer pipes 34 and 35 cannot slide and rotate, and the upper column 22 and the holding member 21 are made substantially the same length as the belt 8. The distance between the bottom 3 and the upper frame 7 is equal at any point. When used on the ground,
It is possible to enhance the stability of the container body 4 in the upright state, and to prevent components such as the holder 21, the belt 8, the side wall 2 and the like from inadvertently tilting or falling down.

When the length adjustment is completed, the falling-off preventing member 41 is locked at the tip of the positioning pin 39. The falling-off prevention member 41 prevents the positioning pin 39 from falling off the outer tube 35. The covering member 42 is elastically deformed and spread, and covers the positioning pin 39 and the drop-off preventing member 41. The covering member 42 attempts to return to the original state by its own elastic restoring force, and the outer tube 35, the positioning pin 39 and the falling-off preventing member 41
Adhere to Due to this close contact, the covering member 42 is also in a state of being locked to the positioning pin 39, the falling-off preventing member 41, and the like, and it is difficult for the covering member 42 to fall off the outer tube 35. Both ends of the positioning pin 39 protrude from the outer tube 35, and the falling-off preventing member 41 is exposed. However, since these projecting portions and exposed portions are covered by the covering member 42, the positioning pin 39
And interference with the other components of the drop-out prevention member 41 can be prevented. Since the covering member 42 itself has elasticity, even if the covering member 42 comes into contact with another component, for example, the side wall portion 2, the covering member 42 elastically deforms to absorb an impact and damage the component. Can be prevented from sticking.

This embodiment has the following features in addition to the items described above.

(A) The guide mechanism G is formed by a very small number of parts such as the guide projection 51 and the guide recess that fit together. In addition, since the guide projection 51 is formed of a tubular body and the lower end 35a of the outer tube 35 also functions as a guide recess, the configuration of the guide mechanism G is very simple. When assembling the guide mechanism G, it is only necessary to insert and fix the tubular body to the lower support 23. For this reason, an increase in cost due to the addition of the guide mechanism G can be minimized, and a failure is unlikely to occur.

(B) When the fire extinguisher sprinkler 1 is suspended and transported by a transport aircraft, the container body 4 receives air resistance and inertia. At this time, as shown in FIG. 5, an angle holding mechanism A provided near the converging portion of the suspension belt 9 is provided.
However, against each of the suspension belts 9 against the air resistance and the inertial force.
Is held wide at a predetermined angle to prevent the suspension belt 9 from being twisted around the convergence portion. Therefore, it is possible to prevent the container body 4 from rotating in the air during transportation.

(C) When at least a part of the connecting member 31 is made of an elastic body (coil spring 32), the member 31 can be expanded and contracted. Moreover, the connecting member 31 is always pulled regardless of the bending and stretching of the upper and lower columns 22, 23. For this reason, the connecting member 31 is connected to the upper and lower columns 2.
There is no rattling in 2,23. The auxiliary connecting member 47 does not rattle in the upper support 22 for the same reason. Generation of abnormal noise due to rattling can be prevented.

(D) The components of the bending and extension connection mechanism B are disposed in the upper and lower columns 22, 23, and the components of the auxiliary connection mechanism F are disposed in the upper column 22. For this reason, these parts are hardly seen from the outside, and are excellent in appearance.

(E) The internal space of the upper and lower columns 22 and 23 is used for disposing the connecting member 31 and the auxiliary connecting member 47 is used.
The inner space of the upper support 22 is used for the arrangement of the upper support 22. For this reason, the ratio of the holder 21 in the storage space 6 is small, which is advantageous in securing a large storage space 6.

(F) As shown in FIGS. 7 and 9, the connecting member 31 may rub against the upper end opening and the lower end opening of the lower support 23 as the lower support 23 tilts. Similarly, as shown in FIG. 6, the auxiliary connecting member 47 may rub against the upper end opening of the upper support 22 as the upper support 22 tilts. The portion of the connecting members 31 and 47 that rubs in this way is a non-elastic chain 3
3,49. For this reason, as compared with the case where elastic members (coil springs 32, 48) are arranged in the above-mentioned portions, the holder 21
Can be effectively prevented from being worn or worn by the connecting members 31 and 47 when is bent and stretched repeatedly.

(G) The upper frame 7 is merely passed through a hole formed at the upper end of the side wall 2 and most of the upper frame 7 is exposed. A portion of the upper frame 7 that is not passed through the hole can be separated from the side wall 2. Therefore, the exposed portion of the upper frame 7 can be used as a handle. There is no need to provide a separate handle.

(H) The entire load acting on the fire-extinguishing sprinkler 1 is taken over by the bottom 3 made of a highly rigid material,
Members other than the bottom part 3, for example, the side wall part 2, are formed of a flexible material. For this reason, the fire extinguisher sprinkler 1 is very simple as a whole, and can easily perform maintenance and repair.

(I) Since the upper frame 7 is supported by a small number of holding members 21 such as two, less work is required when the side wall portion 2 is extended or folded, and the workability is excellent. .

(J) The eye bolt 25 also serves as both a lower projection and a lower locking member, and the bolt 27 also serves as both an upper stopper and an upper locking member. For this reason, the number of parts of the holder 21 can be reduced as compared with the case where these are separately provided.

(K) As a support structure of the upper support 22 and the lower support 23, a method of covering them on the upper protrusion (head 24a) and the lower protrusion (head 25a) is adopted so that the tilt direction is not restricted. ing. Therefore, when the upper and lower columns 22 and 23 are bent and stretched, a problem that an excessive force is applied to the support portion to cause breakage hardly occurs.

The present invention can be embodied in another embodiment described below.

(1) A liquid other than water can be stored in the liquid storage container of the present invention. Such liquids include, for example, oil that has spilled into the sea from fire extinguishers, tankers, and the like.

(2) The support structure of the upper support 22 for the upper frame 7, the support structure for the bottom 3 of the lower support 23, and the structure of the bending and extension connection mechanism B may be appropriately changed. For example, a universal joint may be used for these structures.

(3) As the extension holding mechanism C, for example, a hook-like member is rotatably mounted on one of the upper support 22 and the lower support 23 and a projection is provided on the other. May be hooked on the projection, and the hook-shaped member may be removed from the projection when not in use. Further, a projection may be provided on both the upper support 22 and the lower support 23 so that the hook 21 is hooked on both protrusions when the holder 21 is used.

(4) Instead of rotating the upper frame 7, the container body 4 may be raised or folded simply by raising and lowering.
