[0009] Several embodiments will be described with reference to the drawings. In each embodiment, components that are the same as or similar to those described above will be designated by the same reference numerals, and duplicate detailed descriptions may be omitted as appropriate.

[0010] The hose control device disclosed in each embodiment is attached to, for example, a hose for drainage or water supply. The liquid delivered from the hose is not limited to water, and may be a liquid other than water. The hose control device can be used in applications such as firefighting, disaster prevention, agriculture, and industry.

[0011] FIG. 1 is a diagram showing an example of the schematic configuration of a drainage device 100 according to one embodiment. The drainage device 100 includes a hose control device 1, a pump 2, and a hose H. The hose control device 1 is attached to one end of the hose H. The pump 2 is attached to the other end of the hose H. The pump 2 draws water from a water source 3 and sends the drawn water into the hose H. The water sent into the hose H passes through the hose H and is sent to the hose control device 1. The water sent to the hose control device 1 is discharged from the drain outlet of the hose control device 1 to a drainage field 4. The drainage device 100 configured in this way can discharge water from the water source 3 to the drainage field 4.

[0012] FIG. 2 is a diagram showing another example of the schematic configuration of a drainage device 100 according to one embodiment. The drainage device 100 includes hose control devices 1A and 1B. The hose control device 1A is located at the tip of the drainage device 100. The hose control device 1B is located between the hose control device 1A and the pump 2. A hose H connects the hose control device 1A to the hose control device 1B and the hose control device 1B to the pump 2. Water pumped from a water source 3 by the pump 2 is sent to the hose control device 1A via the hose H and the hose control device 1B and is discharged to a drainage field 4. In this manner, the hose control device 1B may be disposed between the hose control device 1A at the tip of the drainage device 100 and the pump 2. Note that one or more hose control devices 1B may be disposed between the hose control device 1A and the pump 2.

[0013] [First embodiment] FIG. 3 is a diagram showing an example of the configuration of the hose control device 1 according to the first embodiment. The hose control device 1 includes a first member 10, a second member 20, and a ballast unit BA. A hose H is attached to the first member 10. The hose H may be a hose for firefighting, industrial use, agricultural use, or the like. The ballast unit BA connects the first member 10 and the second member 20.

[0014] The hose H has a hose portion HA, a joint portion HB, and a hose band HC. A flow path for flowing liquid such as water is formed inside the hose portion HA. The joint portion HB is provided at the end of the hose portion HA. The joint portion HB is connected to the first member 10. The hose band HC fastens the hose portion HA and the joint portion HB together, for example.

[0015] The first member 10 has a branching portion 10A, a connecting portion 10B, and a plurality of pipes 10C. Flow paths through which a liquid such as water flows are formed inside the branching portion 10A, the connecting portion 10B, and the plurality of pipes 10C, and these flow paths are interconnected. Note that the number of branching paths in the first member 10 is not limited to the example shown in FIG. 3.

[0016] The branching portion 10A has an opening 11A (first opening). For example, a cross-shaped flow path is formed inside the branching portion 10A, penetrating the branching portion 10A, and the opening 11A is in communication with the flow path.

[0017] The connecting portion 10B is provided on the opposite side of the opening 11A across the branch portion 10A. The connecting portion 10B has an inlet 11B. The inlet 11B is connected to the flow path of the branch portion 10A through the flow path of the connecting portion 10B. The connecting portion 10B and the connecting portion HB have a configuration that allows them to be connected to each other. In one example, the connecting portion 10B has a configuration similar to that of the connecting portion HB. By connecting the connecting portion 10B and the connecting portion HB, the flow path of the first member 10 and the flow path of the hose H are connected via the inlet 11B.

[0018] The plurality of pipes 10C are connected to both sides of the branching section 10A, with the branching section 10A in between. In the example shown in FIG. 3, two pipes 10C are connected to both sides of the branching section 10A. In the example shown in FIG. 3, the plurality of pipes 10C have a cylindrical shape and are curved at 90° toward the opening 11A. One end of each of the plurality of pipes 10C is connected to the branching section 10A, and the other end of each of the plurality of pipes 10C is connected to the ballast section BA. An opening 11C (first opening) is provided on the other end side of each of the plurality of pipes 10C. The opening 11C is connected to the flow path of the branching section 10A through the flow path of the pipe 10C.

[0019] The second member 20 has a branching portion 20A, a connecting portion 20B, and a plurality of pipes 20C. Flow paths through which a liquid such as water flows are formed inside the branching portion 20A, the connecting portion 20B, and the plurality of pipes 20C, and these flow paths are interconnected. Note that the number of branching paths in the second member 20 is not limited to the example shown in FIG. 3.

[0020] The branching portion 20A has an opening 21A (second opening). For example, a cross-shaped flow path penetrating the branching portion 20A is formed inside the branching portion 20A, and the opening 21A is in communication with the flow path.

[0021] The coupling portion 20B is provided on the opposite side of the branch portion 20A from the opening 21A. In one example, the coupling portion 20B has a configuration similar to that of the coupling portion 10B and the coupling portion HB. The coupling portion 20B is provided with an outlet 21B. The outlet 21B is in communication with the flow path of the branch portion 20A through the flow path of the coupling portion 20B.

[0022] When the hose control device 1 is placed at the tip of the drainage device 100 as shown in Figure 1, nothing is connected to the connecting portion 20B as shown in the example of Figure 3. On the other hand, when the hose control device 1 is placed between hoses H as shown in Figure 2, the connecting portion HB of the hose H is connected to the connecting portion 20B. When the hose control device 1 is placed at the end of the drainage device 100, water delivered from the hose H is drained from the outlet 21B.

[0023] The plurality of pipes 20C are connected to both sides of the branching section 20A, with the branching section 20A in between. In the example shown in FIG. 3, two pipes 20C are connected to both sides of the branching section 20A. In the example shown in FIG. 3, the plurality of pipes 20C have a cylindrical shape and are curved at 90° toward the opening 21A. One end of each of the plurality of pipes 20C is connected to the branching section 20A, and the other end of each of the plurality of pipes 20C is connected to the ballast section BA. An opening 21C (second opening) is provided on the other end side of each of the plurality of pipes 20C. The opening 21C is connected to the flow path of the branching section 20A through the flow path of the pipe 20C.

[0024] The ballast unit BA has a storage member 60A and a plurality of storage members 60C. In the example shown in FIG. 3, the ballast unit BA has two storage members 60C, but the number of storage members 60C is not limited to two. A flow path through which a liquid such as water flows is formed inside each of the storage members 60A and 60C. Here, the direction in which water flows through the flow paths of the storage members 60A and 60C is defined as the X direction, the direction perpendicular to the X direction is defined as the Y direction, and the vertical direction is defined as the Z direction. In the example shown in FIG. 3, the storage member 60A and the plurality of storage members 60C are aligned in the Y direction.

[0025] One end of each of the storage members 60A and 60C is connected to the first member 10, and the other end of each of the storage members 60A and 60C is connected to the second member 20. Specifically, the storage member 60A is connected to the branching portions 10A and 20A, and the storage member 60C is connected to the pipes 10C and 20C. As a result, the flow paths of the first member 10 and the flow paths of the storage members 60A and 60C are connected via the openings 11A and 11C, and the flow paths of the second member 20 and the flow paths of the storage members 60A and 60C are connected via the openings 21A and 21C. In other words, the flow paths of the first member 10 and the flow paths of the second member 20 are connected via the ballast portion BA.

[0026] The containing members 60A, 60C contain the water sent from the first member 10. In one example, the containing members 60A, 60C are configured to expand due to the internal pressure of the water flowing therethrough. Similar to the hose H, for example, a firefighting, industrial, or agricultural hose can be used for the containing members 60A, 60C. The hose may be formed in a cylindrical shape with a uniform diameter, or may be formed in a shape with a non-uniform cross-sectional shape and cross-sectional area.

[0027] Fig. 4 is a schematic cross-sectional view of the hose control device 1 according to the first embodiment. As shown in the example of Fig. 4, the storage member 60C includes a jacket 61 and a liner 62 lined inside the jacket 61. The jacket 61 is formed, for example, from a cloth woven with warp and weft threads. The liner 62 is formed, for example, from a water-resistant resin. Note that the storage member 60A is also formed of a jacket 61 and a liner 62, similar to the storage member 60C.

[0028] The housing members 60A and 60C can be variously applied depending on the intended use of the hose control device 1, such as an aluminum can, a steel pipe, or a hose made of braided metal.

[0029] The total area of ​​openings 11A and 11C is larger than the area of ​​inlet 11B. Furthermore, the total area of ​​openings 21A and 21C is larger than the area of ​​outlet 21B. In the example shown in Fig. 4, the areas of inlet 11B, openings 11A, 11C, 21A, 21C, and outlet 21B are all equal, but they may be different from one another.

[0030] As described above, the storage member 60A is configured to expand due to the internal pressure of the water flowing therethrough. Therefore, the flow path diameter 61a at the center of the storage member 60A is larger than the flow path diameter 61b at the ends of the storage member 60A. Similarly, the flow path diameter at the center of the storage member 60C is larger than the flow path diameter at the ends of the storage member 60C.

[0031] The white arrows in Figure 4 indicate the direction of water flow through the flow paths of each member. Water sent from hose H first flows into first member 10 through inlet 11B. The water that has flowed into first member 10 is then sent to ballast section BA through openings 11A and 11C and is stored in storage members 60A and 60C of ballast section BA. The water stored in storage members 60A and 60C is then sent to second member 20 through openings 21A and 21C and drained from outlet 21B.

[0032] Fig. 5 is a diagram showing the hose control device 1 when no water is contained in the ballast section BA. If the containing member 60 is flexibly deformable, such as a fire hose, the containing members 60A, 60C will be flattened when no water is contained in the containing members 60A, 60C, as shown in Fig. 5.

[0033] 6 is a schematic partial cross-sectional view of a configuration that can be applied to the coupling portion 10B. The coupling portion 10B includes a first cylindrical portion 51 and a second cylindrical portion 52 provided on the outer peripheral surface of the first cylindrical portion 51. In this embodiment, the direction parallel to the axis AX of the coupling portion 10B (the axis of the first cylindrical portion 51 and the second cylindrical portion 52) is called the axial direction DX, the direction away from the axis AX is called the radial direction DR, and the circumferential direction around the axis AX is called the circumferential direction Dθ.

[0034] A flow path for water to flow is formed inside the first cylindrical portion 51. An annular seal member 53 is provided at an end portion 51a of the first cylindrical portion 51.

[0035] The second cylindrical portion 52 has a plurality of hooks 54 protruding in the axial direction DX from the end portion 51a of the first cylindrical portion 51. These hooks 54 are arranged at regular intervals in the circumferential direction Dθ. Recesses 55 are formed between adjacent hooks 54. Like the hooks 54, these recesses 55 are arranged at regular intervals in the circumferential direction Dθ.

[0036] The hook 54 has a first side surface 541 and a second side surface 542 in the circumferential direction Dθ. The second side surface 542 is inclined with respect to the axial direction DX. As a result, the width of the hook 54 in the circumferential direction Dθ decreases toward the tip.

[0037] The first side surface 541 is provided with a claw portion 56 protruding in the circumferential direction Dθ and a recess 57 located closer to the base of the hook 54 than the claw portion 56. The second side surface 542 is provided with a ball plunger 58. For example, the ball plunger 58 includes a hole portion provided in the second side surface 542, a ball housed in the hole portion, and an elastic body that urges the ball toward the outside of the hole portion. A portion of the ball protrudes from the second side surface 542.

[0038] The configuration of the coupling part HB is the same as that of the coupling part 10B, that is, the coupling part HB has a plurality of hooks 54 having the same shape as the hooks 54 of the coupling part 10B and a plurality of recesses 55 having the same shape as the recesses 55 of the coupling part 10B.

[0039] 7 is a side view showing a portion of the coupled joint 10B of the first member 10 and the coupled joint HB of the hose H. When coupling the joint 10B and the joint HB, the axes AX of these joints are aligned and the joint HB is pressed against the joint 10B. At this time, the hooks 54 of the joint HB are inserted into the recesses 55 of the joint 10B, and the hooks 54 of the joint 10B are inserted into the recesses 55 of the joint HB.

[0040] When the connecting portion HB is pushed into the connecting portion 10B to the maximum extent, the ball plungers 58 of both come into contact and press against each other, causing the connecting portion HB to rotate slightly in the circumferential direction Dθ. At this time, the claws 56 of both engage with each other and are prevented from coming off in the axial direction DX.

[0041] Once the coupling portion 10B and the coupling portion HB are coupled together, the coupled state is maintained by the biasing force of the ball plunger 58. To release the coupling between the coupling portion 10B and the coupling portion HB, the coupling portion HB is rotated in the circumferential direction Dθ relative to the coupling portion 10B against the biasing force of the ball plunger 58. This releases the engagement of the claw portions 56.

[0042] The structure of the connecting portions 10B, HB described above can also be applied to the connecting portion 20B shown in Fig. 3. It can also be used to connect the first member 10 and the ballast portion BA, and the second member 20 and the ballast portion BA. The method of connecting the members is not limited to the above example. For example, the connecting portion 10B, which is made up of a male metal fitting, and the connecting portion HB, which is made up of a female metal fitting, may be engaged with each other to connect them.

[0043] For example, when draining water from the tip of the hose H without the hose control device 1 attached to the tip of the hose H, the tip of the hose H may become unsteady depending on factors such as the diameter of the tip of the hose H, the flow rate of water flowing through the hose H, and the water pressure.

[0044] In this embodiment, a hose control device 1 is attached to the tip of a hose H. Water sent from the hose H is stored in a ballast section BA. As a result, the mass of the ballast section BA increases by the mass of the water stored in the ballast section BA. By increasing the mass of the ballast section BA, the ballast section BA functions as a weight, making it possible to suppress the movement of the hose H.

[0045] The mass of the ballast section BA can also be increased by increasing the number of branches of the first member 10 and the second member 20 and the number of storage members 60A, 60C. Furthermore, the mass of the ballast section BA can also be increased by increasing the flow path diameters 61a, 61b and lengths of the storage members 60A, 60C.

[0046] In this embodiment, the storage members 60A and 60C are arranged in the Y direction, which is perpendicular to the X direction in which water flows through the flow paths of the storage members 60A and 60C. This allows the hose control device 1 to suppress twisting of the hose H when supplying or discharging water, and rolling of the hose H due to twisting.

[0047] 6 and 7 are applied to the connection between the first member 10 and the ballast section BA, and the connection between the second member 20 and the ballast section BA, the first member 10, the second member 20, and the ballast section BA can be connected and disconnected. This allows each part to be transported and stored separately, improving the convenience of the hose control device 1. Furthermore, because each part can be combined in various ways, the hose control device 1 can be used by rearranging the parts depending on the intended use and environment.

[0048] [Second embodiment] 8 is a diagram showing an example of the configuration of a hose control device 1 according to the second embodiment. In addition to the first member 10, second member 20, and ballast section BA described above, the hose control device 1 according to the second embodiment further includes a third member 30. The third member 30 is attached to the outlet 21B of the second member 20. The third member 30 has a flow path therein whose diameter increases with increasing distance from the outlet 21B.

[0049] The third member 30 is joined to the joining portion 20B of the second member 20. The second member 20 and the third member 30 are joined by, for example, the joining method described above with reference to Figures 6 and 7. By joining the third member 30 to the joining portion 20B, the flow path of the second member 20 and the flow path of the third member 30 are connected via the outlet 21B.

[0050] The third member 30 has an opening 32 (third opening). The area of ​​the opening 32 is larger than the area of ​​the outlet 21B. Water flowing out from the second member 20 passes through the outlet 21B and flows into the third member 30. The water that has flowed into the third member 30 passes through a flow path within the third member 30 and is discharged from the opening 32.

[0051] The second embodiment can also achieve the same effects as the first embodiment. In the second embodiment, the third member 30 is attached to the outlet 21B of the second member 20. Because the opening 32 of the third member 30 has a larger area than the outlet 21B, the flow rate of the water passing through the opening 32 is lower than the flow rate of the water passing through the outlet 21B. This can further suppress the movement of the hose H.

[0052] [Third embodiment] 9 is a diagram showing an example of the configuration of a hose control device 1 according to the third embodiment. The hose control device 1 according to the third embodiment further includes a fourth member 40 in addition to the first member 10, second member 20, and ballast section BA described above. The fourth member 40 is attached to the outlet 21B of the second member 20. The fourth member 40 has a flow path therein that branches into multiple paths.

[0053] The fourth member 40 is joined to the joining portion 20B of the second member 20. The second member 20 and the fourth member 40 are joined by, for example, the joining method described above with reference to Figures 6 and 7. By joining the fourth member 40 to the joining portion 20B, the flow path of the second member 20 and the flow path of the fourth member 40 are connected via the outlet 21B.

[0054] The fourth member 40 has a plurality of openings 42 (fourth openings). In the example shown in FIG. 9, the fourth member 40 has two openings 42. The total area of ​​the plurality of openings 42 is larger than the area of ​​the outlet 21B. Water flowing out from the second member 20 passes through the outlet 21B and flows into the fourth member 40. The water that has flowed into the fourth member 40 passes through a flow path within the fourth member 40 and is discharged from the plurality of openings 42.

[0055] The third embodiment also provides the same effects as the first embodiment. In the third embodiment, the fourth member 40 is attached to the outlet 21B of the second member 20. Because the total area of ​​the multiple openings 42 of the fourth member 40 is larger than the area of ​​the outlet 21B, the flow rate of water passing through the multiple openings 42 is lower than the flow rate of water passing through the outlet 21B. This makes it possible to further suppress the movement of the hose H.

[0056] [Fourth embodiment] 10 is a diagram showing an example of the configuration of a hose control device 1 according to the fourth embodiment. The hose control device 1 according to the fourth embodiment further includes a first member 15 and a second member 25 in addition to the first member 10, the second member 20, and the ballast section BA described above.

[0057] First member 15 has branching portion 15A, connecting portions 15B and 15D, and a plurality of pipes 15C. Flow paths through which a liquid such as water flows are formed inside branching portion 15A, connecting portions 15B and 15D, and a plurality of pipes 15C, respectively, and these flow paths are in communication with each other.

[0058] For example, a cross-shaped flow path is formed inside branch portion 15A, penetrating branch portion 15A. Joining portions 15B and 15D are provided on either side of branch portion 15A, sandwiching branch portion 15A therebetween. Joining portion 15B has inlet 16B. Inlet 16B communicates with the flow path of branch portion 15A through the flow path of joining portion 15B. Joining portion 15D has opening 16D. Opening 16D communicates with the flow path of branch portion 15A through the flow path of joining portion 15D.

[0059] The plurality of pipes 15C are connected to both sides of the branching portion 15A, sandwiching the branching portion 15A. In the example shown in FIG. 10, two pipes 15C are connected to both sides of the branching portion 15A. In the example shown in FIG. 10, the plurality of pipes 15C have a cylindrical shape and are curved at 90° toward the opening 16A. The radius of curvature of the plurality of pipes 15C is larger than the radius of curvature of the plurality of pipes 10C. One end of each of the plurality of pipes 15C is connected to the branching portion 15A, and the other end of each of the plurality of pipes 15C is connected to the ballast section BA. An opening 16C (first opening) is provided on the other end side of each of the plurality of pipes 15C. The opening 16C is connected to the flow path of the branching portion 15A through the flow path of the pipe 15C.

[0060] Joining portion 15B is joined to joining portion HB of hose H, and joining portion 15D is joined to joining portion 10B of first member 10. Joining portion 15B and joining portion HB, and joining portion 15D and joining portion 10B are joined by, for example, the joining method described above with reference to Figures 6 and 7. Joining joining portion 15B and joining portion HB connects the flow path of first member 15 to the flow path of hose H via inlet 16B. Similarly, joining joining portion 10B and joining portion 15D connects the flow path of first member 10 to the flow path of first member 15 via inlet 11B and opening 16D.

[0061] Second member 25 has branching portion 25A, connecting portions 25B and 25D, and a plurality of pipes 25C. Flow paths through which a liquid such as water flows are formed inside branching portion 25A, connecting portions 25B and 25D, and a plurality of pipes 25C, respectively, and these flow paths are in communication with each other.

[0062] For example, a cross-shaped flow path is formed inside branch portion 25A, penetrating branch portion 25A. Joining portions 25B and 25D are provided on both sides of branch portion 25A, sandwiching branch portion 25A therebetween. Joining portion 25B has outlet 26B. Outlet 26B communicates with the flow path of branch portion 25A through the flow path of joining portion 25B. Joining portion 25D has opening 26D. Opening 26D communicates with the flow path of branch portion 25A through the flow path of joining portion 25D.

[0063] The plurality of pipes 25C are connected to both sides of the branching portion 25A, sandwiching the branching portion 25A. In the example shown in FIG. 10, two pipes 25C are connected to both sides of the branching portion 25A. In the example shown in FIG. 10, the plurality of pipes 25C have a cylindrical shape and are curved at 90° toward the opening 26A. The radius of curvature of the plurality of pipes 15C is larger than the radius of curvature of the plurality of pipes 10C. One end of each of the plurality of pipes 25C is connected to the branching portion 20A, and the other end of each of the plurality of pipes 25C is connected to the ballast portion BA. An opening 26C (second opening) is provided on the other end side of each of the plurality of pipes 25C. The opening 26C is connected to the flow path of the branching portion 25A through the flow path of the pipe 25C.

[0064] The coupling portion 25D is coupled to the coupling portion 20B of the second member 20. The coupling portion 25D and the coupling portion 20B are coupled together by, for example, the coupling method described above with reference to Figures 6 and 7. By coupling the coupling portion 20B and the coupling portion 25D together, the flow path of the second member 20 and the flow path of the second member 25 are connected together via the outlet 21B and the opening 26D.

[0065] The ballast unit BA has a plurality of storage members 65C in addition to the above-mentioned storage member 60A and a plurality of storage members 60C. In the example shown in Fig. 10, the ballast unit BA has two storage members 65C, but the number of storage members 65C is not limited to two. The plurality of storage members 65C are configured similarly to the storage members 60A and 60C, and flow paths through which liquid such as water flows are formed inside the plurality of storage members 65C.

[0066] One end of the storage member 65C is connected to the first member 15, and the other end of the storage member 65C is connected to the second member 25. Specifically, one end of the storage member 65C is connected to the piping 15C, and the other end of the storage member 65C is connected to the piping 25C. As a result, the flow path of the first member 15 and the flow path of the storage member 65C are connected via the opening 16C, and the flow path of the second member 25 and the flow path of the storage member 65C are connected via the opening 26C. In other words, the flow path of the first member 15 and the flow path of the second member 25 are connected via the ballast section BA.

[0067] The containing member 65C contains the water sent from the first member 15. In one example, the containing member 65C is configured to expand due to the internal pressure of the water flowing therethrough. Similar to the hose H, a hose for firefighting, industrial use, agricultural use, or the like can be used for the containing member 65C. The hose may be formed in a cylindrical shape with a uniform diameter, or may be formed in a shape with a non-uniform cross-sectional shape and cross-sectional area.

[0068] Water sent from hose H first flows into first member 15 through inlet 16B. Thereafter, the water that has flowed into first member 15 is sent to first member 10 and the plurality of storage members 65C. As described above, the water sent to first member 10 is stored in storage members 60A and 60C and sent to second member 20. The water sent to second member 20 is sent to second member 25 through outlet 21B and opening 26D. Meanwhile, water sent from first member 15 to storage member 65C is stored in storage member 65C and sent to second member 25 through opening 26C. The water sent to second member 25 is drained from outlet 26B.

[0069] The fourth embodiment also provides the same effects as the first embodiment. Furthermore, in the fourth embodiment, the ballast unit BA includes a storage member 65C in addition to the storage members 60A and 60C. Therefore, the ballast unit BA can store more water than the first embodiment, enhancing its function as a weight. This makes it possible to further suppress the movement of the hose H.

[0070] [Fifth embodiment] 11 is a diagram showing an example of the configuration of a hose control device 1 according to the fifth embodiment. The hose control device 1 according to the fifth embodiment includes a first member 10, a second member 20, and a ballast portion BA.

[0071] The first member 10 has a single opening 11A (first opening) and an inlet 11B. The area of ​​the opening 11A is larger than the area of ​​the inlet 11B. A coupling portion HB of a hose H is connected to the inlet 11B. A ballast portion BA is connected to the opening 11A. The hose H and the first member 10, and the first member 10 and the ballast portion BA are coupled together using, for example, the coupling method described above with reference to Figures 6 and 7. The first member 10 has a flow path therein whose diameter increases from the inlet 11B toward the opening 11A.

[0072] The second member 20 has a single opening 21A (second opening) and an outlet 21B. The area of ​​opening 21A is larger than the area of ​​outlet 21B. A ballast part BA is connected to opening 21A. The second member 20 and ballast part BA are connected by the connecting method described above with reference to Figures 6 and 7, for example. The second member 20 has a flow path therein whose diameter decreases from opening 21A toward outlet 21B.

[0073] The ballast section BA has a single storage member 60A. One end of the storage member 60A is connected to the first member 10 via an opening 11A, and the other end of the storage member 60A is connected to the second member 20 via an opening 21A. The storage member 60A is configured similarly to the storage members 60A and 60C described with reference to Figures 3 and 4.

[0074] Water sent from hose H to first member 10 via inlet 11B passes through the flow path of first member 10 and is sent to ballast section BA via opening 11A. The water sent to ballast section BA is then stored in storage member 60 and sent to second member 20 via opening 21A. The water sent to second member 20 then passes through the flow path of second member 20 and is drained from outlet 21B.

[0075] In the fifth embodiment, the ballast section BA has a single housing member 60. Even in such a configuration, the ballast section BA functions as a weight, making it possible to suppress the hose H from moving wildly.

[0076] [Sixth embodiment] 12 is a diagram showing an example of the configuration of a hose control device 1 according to a sixth embodiment. The hose control device 1 according to the sixth embodiment includes a first member 10 and a ballast unit BA. The hose H and the ballast unit BA are connected to the first member 10.

[0077] The first member 10 has a branching portion 10A, connecting portions 10B and 10D, and a plurality of pipes 10C. Flow paths through which a liquid such as water flows are formed inside the branching portion 10A, connecting portions 10B and 10D, and the plurality of pipes 10C, and these flow paths are connected to each other.

[0078] The branching section 10A and the connecting section 10B have the same configuration as the branching section 10A and the connecting section 10B of the first embodiment shown in FIGS. 3 and 4. In the example shown in FIG. 12, two pipes 10C are connected to the branching section 10A. In the example shown in FIG. 12, the multiple pipes 10C have a cylindrical shape and are curved at 90° toward the inlet 11B. One end of each of the multiple pipes 10C is connected to the branching section 10A, and the other end of each of the multiple pipes 10C is connected to the ballast section BA. An opening 11C (first opening) is provided on the other end side of each of the multiple pipes 10C. The connecting section 10D is provided on the opposite side of the branching section 10A from the connecting section 10B, and has an outlet 11D.

[0079] The ballast section BA has a plurality of storage members 60C, a plurality of joints EL, and a storage member 60E. In the example shown in FIG. 12, the ballast section BA has two storage members 60C and two joints EL, but the number of storage members 60C and joints EL is not limited to two. The storage members 60C and 60E are configured similarly to the storage members 60A and 60C of the first embodiment shown in FIGS. 3 and 4. In the example shown in FIG. 12, the storage member 60C has a longer flow path than the storage member 60E and can store more water than the storage member 60E. The joint EL has a cylindrical shape and is curved at 90°. Note that the curved angle of the joint EL is not limited to 90°.

[0080] Both ends of the ballast section BA are attached to the openings 11C, respectively. Specifically, one end of each of the two storage members 60C is connected to an opening 11C. The other end of each of the two storage members 60C is connected to one end of each of the two joints EL. The storage member 60E is connected to the other end of each of the two joints EL.

[0081] Water sent from hose H first flows into first member 10 through inlet 11B. Then, part of the water that has flowed into first member 10 is sent to ballast section BA, and the remainder is drained from outlet 11D. The water sent to ballast section BA passes through multiple storage members 60C and multiple joints EL and is sent to storage member 60E. As a result, water is stored in multiple storage members 60C and storage member 60E.

[0082] When water is stored in the ballast section BA, the ballast section BA is in contact with the hose H in the Z direction. In the example shown in FIG. 12, the storage member 60E is in contact with the hose H in the Z direction. Note that the storage member 60C may also be in contact with the hose H in the Z direction. In addition, in the example shown in FIG. 12, the hose H is positioned above the storage member 60E.

[0083] For example, when water is delivered using hose H, the water pressure of the water flowing through hose H may cause hose H to stretch, which may cause hose H to meander. As a result, hose H may move unintentionally.

[0084] In the sixth embodiment, when water is stored in the ballast section BA, the storage member 60E expands, and the hose H is lifted by the storage member 60E. As the hose H is lifted, the expansion of the hose H is released in the Z direction, and meandering of the hose H can be suppressed. This makes it possible to mitigate unintended movement of the hose H. In addition, the sixth embodiment can also achieve the same effects as the first embodiment.

[0085] Fig. 13 is a diagram showing another example of the configuration of the hose control device 1 according to the sixth embodiment. In the example shown in Fig. 13, the hose H is located below the housing member 60E. Therefore, a load equivalent to the mass of the ballast section BA and the mass of the water housed in the ballast section BA is applied to the hose H. This makes it possible to further suppress the movement of the hose H.

[0086] [Seventh embodiment] FIG. 14 is a diagram showing an example of the configuration of a hose control device 1 according to the seventh embodiment. The ballast section BA of the hose control device 1 according to the seventh embodiment has a plurality of storage members 60C and a plurality of caps CP. In the example shown in FIG. 14, the ballast section BA has two storage members 60C and two caps CP, but the number of storage members 60C and caps CP is not limited to two. One end of each of the plurality of storage members 60C is connected to the opening 11C. The other end of each of the plurality of storage members 60C is sealed by the cap CP.

[0087] In the seventh embodiment, water is stored in a plurality of storage members 60C whose ends are sealed with caps CP, and the ballast portion BA functions as a weight. This makes it possible to suppress the movement of the hose H. The ends of the storage members 60C may be sealed by sewing or adhesive. In addition, the seventh embodiment can also achieve the same effects as the first embodiment.

[0088] Fig. 15 is a diagram showing another example of the configuration of the hose control device 1 according to the seventh embodiment. In the example shown in Fig. 15, the ballast portion BA is connected to the branch portion 10A of the first member 10. Specifically, the storage member 60C is connected to an opening 11A (first opening) provided in the branch portion 10A.

[0089] 15, the axis passing through the center of opening 11A is perpendicular to the axis passing through the center of outlet 11D. Therefore, housing member 60C extends in a direction (X direction) perpendicular to the direction (Y direction) in which water is discharged from outlet 11D. This allows hose control device 1 to suppress twisting of hose H when water is supplied or discharged, and rolling of hose H due to twisting.

[0090] FIG. 16 is a diagram showing yet another configuration example of the hose control device 1 according to the seventh embodiment. In the example shown in FIG. 16, another first member 10 to which a ballast section BA is connected is connected to the outlet 11D side of the first member 10 shown in FIG. 15. In this way, the number of storage members 60C may be increased by connecting multiple first members 10. This allows the hose control device 1 to further suppress twisting of the hose H when water is being supplied or discharged, and rolling of the hose H due to twisting.

[0091] [Eighth embodiment] 17 is a diagram showing an example of the configuration of a hose control device 1 according to an eighth embodiment. The hose control device 1 according to the eighth embodiment has a first member 10, a ballast section BA, a plurality of pipes PP, and a plurality of fixing devices CH.

[0092] The first member 10 has a joint portion 12 and connecting portions 10B and 10D. The joint portion 12 is formed in a cylindrical shape. The connecting portions 10B and 10D are provided on both sides of the joint portion 12, sandwiching the joint portion 12. The connecting portions 10B and 10D have a configuration similar to that of the connecting portions 10B and 10D of the sixth embodiment, for example.

[0093] The ballast section BA has a plurality of storage members 60C, 60E and a plurality of joints EL. In the example shown in Fig. 17, the ballast section BA has two storage members 60C, two storage members 60E, and four joints EL, but the number of storage members 60C, 60E, and joints EL is not limited to this. One end of each of the plurality of joints EL is connected to one end of each of the plurality of storage members 60C, and the other end of each of the plurality of joints EL is connected to the other end of each of the plurality of storage members 60E. In the example shown in Fig. 17, the first member 10 is in contact with the plurality of storage members 60C.

[0094] The multiple pipes PP connect the first member 10 and the ballast unit BA. In the example shown in Fig. 17, the multiple pipes PP connect the joint unit 12 and the joint EL. The multiple pipes PP may also connect the joint unit 12 and the storage members 60C, 60E. The joint unit 12 and the joint EL have openings that communicate with the flow paths in the multiple pipes PP.

[0095] 17, the number of the plurality of pipes PP is four. However, the number of pipes PP is not limited to this and may be, for example, one. The pipes PP may be, for example, flexible hoses or pipes made of metal or resin.

[0096] The plurality of fasteners CH connect the first member 10 and the ballast portion BA. In the example shown in FIG. 17, the plurality of fasteners CH connect the joint portion 12 and the joint EL. In the example shown in FIG. 17, the number of fasteners CH is four. However, the number of fasteners CH is not limited to this. For example, a metal chain may be used as the fastener CH.

[0097] Water sent from hose H first flows into first member 10 through inlet 11B. Then, part of the water that has flowed into first member 10 is sent to ballast section BA through pipe PP, and the remainder is drained from outlet 11D. The water sent to ballast section BA passes through joint EL and is sent to storage members 60C and 60E. As a result, water is stored in storage members 60C and 60E.

[0098] In the eighth embodiment, the first member 10 and the ballast section BA are connected by a pipe PP. Water sent from the hose H to the first member 10 passes through the pipe PP and is stored in the ballast section BA. This allows the ballast section BA to function as a weight and suppress the movement of the hose H. In this way, the first member 10 and the ballast section BA do not have to be directly connected.

[0099] Furthermore, the first member 10 is fixed to the ballast part BA by a fixing device CH. This increases the stability of the posture of the first member 10, making it possible to further suppress the movement of the hose H. In addition, the eighth embodiment can also achieve the same effects as the first embodiment.

[0100] The scope of the present invention is not limited to the configurations disclosed in the above embodiments. The present invention can be implemented by modifying the configurations disclosed in the embodiments in various ways. The configurations disclosed in the embodiments can be combined as needed.
