[Device configuration]
FIG. 1 is a diagram showing a schematic structure of a rescue device 1A according to the first embodiment. FIG. 1 shows a schematic structure of a rescue device 1A viewed from the side. Hereinafter, a rescue device 1A according to this embodiment will be explained using FIG. 1. In this embodiment, an example will be described in which a rescue device 1A is permanently installed in a bathtub 2.

The reference numeral 2A shown in FIG. 1 is a liquid storage area formed inside the bathtub 2, and hot water is stored in the liquid storage area 2A. The bathtub 2 has a bottom wall 21 and a plurality of side walls 22 erected from the bottom wall 21. 22A and 22B shown in FIG. 1 are a pair of opposing side walls. The rescue device 1A according to this embodiment includes a rescue tool 10 and a hoisting device 100. The rescue tool 10 includes a floating section 4, a towing rope 5, a fixing rope 6, and the like.

FIG. 2 is a perspective view of the rescue tool 10 according to the first embodiment. The rescue tool 10 includes a floating section 4, a towing rope 5, a fixing rope 6, and the like. One end of a towing rope 5 is connected to one end of the floating section 4 . Further, one end of a fixing rope 6 is connected to the other end of the floating part 4. Further, the floating section 4 is a member that can support the rescue object 3 with a support surface 41 formed on its upper surface when the rescue object 3 is rescued. The floating part 4 has a size and shape suitable for supporting the rescue target 3, and has a substantially rectangular mat shape in the example shown in FIG. In this embodiment, the floating part 4 has a porous structure in which a large number (plurality) of through holes 42 are formed. The through hole 42 penetrates the floating portion 4 in the thickness direction of the member. Therefore, the floating portion 4 can transmit hot water stored in the liquid storage area 2A through each through hole 42. Of course, as is clear from FIG. 2, the through hole 42 of the floating part 4 has a size that does not hinder the support of the rescue object 3 by the support surface 41. Further, in this embodiment, the floating portion 4 is formed of a flexible material. For example, in this embodiment, the floating portion 4 is made of silicone rubber. However, in this embodiment, the material of the floating part 4 is not particularly limited, and does not need to have flexibility. Moreover, in this embodiment, an example is shown in which the rescue target 3 is a human being. However, the rescue target 3 is not limited to humans, but also includes animals other than humans, and can be changed as appropriate depending on the purpose. For example, the rescue device according to the present disclosure may be used outdoors to rescue animals other than humans.

As shown in FIG. 1, the towing rope 5 is configured to be pulled by a hoisting device 100 installed on the side wall 22A. On the other hand, the other end of the fixing rope 6 is fixed to a fixing portion 7 of a side wall 22B located on the opposite side to the side wall 22A on which the hoisting device 100 is installed. The fixing part 7 may be an appropriate mooring member such as a round ring, a carabiner, a hook, etc., which can moor the fixing rope 6, for example. The traction rope 5 and the fixing rope 6 can be formed of appropriate members such as a rubber belt, a cloth belt, a metal wire, etc., but the material and form thereof are not particularly limited. In addition, when using a metal wire for the traction rope 5 and the fixing rope 6, the metal wire may be covered with a protective tube (cover) or the like. Further, in this embodiment, the fixing part 7 is fixed to the side wall 22B, but the fixing part 7 is not limited to this, and the fixing part 7 can be fixed to a place other than the side wall 22B or via another member fixed to the side wall 22B. It may be fixed in an appropriate manner.

In the example shown in FIG. 1, the other end of the floating part 4 is fixed to the side wall 22B of the bathtub 2 via the fixing rope 6, but the other end of the floating part 4 is welded to the side wall 22B. They may also be directly joined by bolting or bolting. From the viewpoint of inspection and maintenance of the rescue tool 10, it is desirable that the fixing part 7, the fixing rope 6, the fixing rope 6 and the towing rope 5, and the floating part 4 are each detachable. In particular, by making each of the

ropes

5 and 6 detachable from the floating part 4, the floating part 4 can be cleaned regularly, and the floating part 4 can be kept clean.

The winding device 100 may be, for example, an electric winch, a manual winding device, or the like. However, the winding device 100 only needs to be able to wind up the towing rope 5 during operation, and the above embodiment is merely an example. In the example shown in FIG. 1, the winding device 100 is installed on the upper edge of the side wall 22A, but the manner in which the winding device 100 is installed is not particularly limited. For example, the hoisting device 100 may be installed inside the side wall 22A. In this case, an insertion opening through which the towing rope 5 is inserted may be formed in the side wall 22A. In this way, by making the hoisting device 100 an embedded type, the rescue device 1A can be made more compact. Moreover, as another aspect, the hoisting device 100 may be embedded in the wall of the bathroom. In either case, the hoisting device 100 is fixed to a strong location so that it can support the weight of the rescue target. Furthermore, the fixing portion for fixing the fixing rope 6 is also fixed to a sufficiently strong location. If used in this state, the shaking of the entire rescue device due to vibration during operation can be reduced, and the rescue target can be rescued more reliably.

Note that in this embodiment, the hoisting device 100 may be able to operate in both the winding direction of winding up the towing rope 5 and the sending direction of sending out (pulling out) the towing rope 5. When the winding device 100 is operated in the winding direction, the floating section 4 can be raised toward the liquid level. On the other hand, when the hoisting device 100 is operated in the sending direction, the floating section 4 can be lowered (sinked) toward the bottom of the liquid.

[motion]
Next, the operation of the rescue device 1A will be explained with reference to FIG. As shown in FIG. 1, under normal conditions before operating the rescue device 1A, the floating part 4 of the rescue tool 10 is submerged (sinking) below the liquid surface (in the liquid) of the liquid storage area 2A. It is located. In this way, the position where the floating section 4 is normally placed is called the initial depth. In FIG. 1, the floating portion 4 placed at the initial depth is shown by a chain line. Normally, with the floating portion 4 disposed at the initial depth, the user can, for example, soak in hot water stored in the liquid storage area 2A in the bathtub 2. That is, the floating portion 4 of the rescue device 1A is normally set at the above-mentioned initial depth so that the user can fully immerse himself in the hot water stored in the bathtub 2. In the example shown in FIG. 1, the floating part 4 (dashed line) placed at the initial depth is sunk to a depth near the bottom of the liquid storage area 2A. It may also be placed at the bottom of the liquid. In this way, the initial depth of the floating portion 4 placed in the bathtub 2 during normal times can be set to an appropriate depth. Moreover, when the floating part 4 in this embodiment is used in contact with the bottom wall 21, if the floating part 4 is flexible, even if the shape of the bottom wall 21 of the bathtub 2 is not flat, the bottom The floating portion 4 can be arranged along the shape of the wall 21.

Next, when the user drowns due to some reason, the hoisting device 100 is activated to rescue the drowning user, that is, the rescue target 3. Specifically, the winding device 100 is operated in the winding direction. As a result, the traction rope 5 is wound up by the winding device 100. Here, as shown in FIG. 1, a towing rope 5 is connected to one end of the floating part 4, and a fixing rope 6 connected to the other end of the floating part 4 is fixed to a fixing part 7 of the side wall 22B. . Therefore, as the winding device 100 winds up the towing rope 5 as described above, the floating section 4 rises from the above-mentioned initial depth toward the liquid level. Thereby, the rescue object 3 can be levitated toward the liquid level while the rescue object 3 is supported by the support surface 41 from below by the floating section 4. Thereby, the rescue object 3 drowning in the liquid storage area 2A can be rescued.

In FIG. 1, the rescue tool 10 in a state in which the rescue of the rescue target 3 has been completed is shown by a solid line. In the example shown in FIG. 1, the entire rescue target 3 is exposed above the liquid surface, but the present invention is not limited to this. For example, when rescuing the rescue object 3, the floating section 4 may be raised to such an extent that at least the face of the rescue object 3 can be exposed above the liquid surface.

[Action/Effect]
As described above, according to the rescue device 1A according to the present embodiment, when rescuing the rescue object 3, the floating section 4 is raised by the hoisting device 100, thereby moving the rescue object 3 submerged in the liquid toward the liquid surface. Can be levitated. As a result, it becomes possible to quickly rescue the rescue object 3 drowning in the liquid storage area 2A. Furthermore, in this embodiment, the hoisting device 100 is permanently installed on the side wall 22A, which is a member that defines the liquid storage area 2A, and there is no need to transport the rescue device from another location. You can shorten the time it takes.

Moreover, according to the rescue tool 10 according to the present embodiment, the towing rope 5 is connected to one end of the floating part 4 and the fixing rope 6 is connected to the other end of the floating part 4. It becomes easier to rescue the rescue target 3 while holding the support surface 41 upward. Further, as described above, since the floating part 4 has a porous structure in which a large number (plurality) of through holes 42 are formed, when the traction rope 5 is hoisted up by the hoisting device 100, hot water or water on the support surface 41 side The floating part 4 can be raised while passing water through the through hole 42 to the back surface 43 side of the floating part 4. According to this, when the floating part 4 is operated by the hoisting device 100, the floating part 4 can be made less susceptible to the resistance of hot water, and the floating part 4 can be operated smoothly. In addition, in this embodiment, if the floating part 4 has flexibility, it is not necessarily necessary to provide the towing rope 5 and the fixing rope 6, and it is also possible to adopt a mode in which these are omitted. . In this case, one end of the floating part 4 may be directly wound up by the winding device 100, and the other end of the floating part 4 may be directly fixed to the bathtub 2. In this embodiment, the floating section 4 can serve as the towing rope 5 and the fixing rope 6.

Furthermore, since the hoisting device 100 according to the present embodiment can also be operated in the feeding direction, after the rescue target 3 is rescued, when the bathtub 2 is used normally, the flotation unit 4 is moved toward the bottom of the liquid again. The rescue device 1A can be lowered (sinked) and used repeatedly.

In this embodiment, the initial depth at which the floating portion 4 is submerged in the liquid storage area 2A is not particularly limited. In addition, as described above, the rescue device 1A can be applied to various liquid storage areas such as chemical baths, pools, ponds, fishing ponds, hot springs, etc. in addition to the bathtub 2, but the rescue device 1A can be applied to ponds, fishing ponds, etc. In such a case, the size of the through hole 42 in the floating part 4 may be set so that a fish or the like can pass through it. It can also be used in locations where flow or circulation occurs due to inflow or discharge of liquid within the liquid storage area 2A. Moreover, in this embodiment, the form of the floating part 4 is not particularly limited, and may have a net-like form, for example. Further, the floating portion 4 does not necessarily have to be flexible, and may be formed of a hard material such as metal, carbon, or resin. Moreover, the floating part 4 may perform anti-slip treatment on the support surface 41 that supports the rescue target 3. By performing the anti-slip treatment, it is possible to obtain the effect of preventing the rescue object 3 from falling from the floating section 4 when the rescue device 1A is activated.

However, the aspect of the cylinder lifting device 220 is just an example, and is not limited thereto.

The backing plate 222 is interposed between the back surface 43 of the floating part 4 and the bottom wall 21 (liquid bottom), and its first end 222A is hinged to the bottom wall 21 (liquid bottom) of the bathtub 2. On the other hand, the second end 222B of the backing plate 222 is slidably in contact with the back surface 43 of the floating part 4. In this embodiment, the cross-sectional shape of the second end 222B of the backing plate 222 is rounded, and the second end 222B can slide along a guide rail (not shown) provided on the back surface 43 of the floating section 4. It has become. The structure is such that the rod 221B of the air cylinder 221 comes into contact with a position slightly moved in the direction of the second end 222B from the hinged portion of the first end 222A of the backing plate 222 and lifts it up. With this structure, the second end 222B is lifted up using the hinged portion of the first end 222A as a fulcrum. Furthermore, the backing plate 222 shown in FIG. 7 is made of a reinforced plastic material and has a generally rectangular shape that is large enough to fit inside the bathtub 2. However, the aspect of the backing plate 222 is one example, and the present invention is not limited to this.

[motion]
Under normal conditions, the rod 221B of the air cylinder 221 of the cylinder lifting device 220 is in a shortened state. In this state, as shown by the chain line in FIG. 7, the patch plate 222 is in a collapsed position with respect to the bottom wall 21 (liquid bottom), and the floating portion 4 is stacked on the patch plate 222. , is submerged in the liquid at an initial depth near the bottom wall 21 (liquid bottom) of the bathtub 2. When the rescue target 3 drowns, compressed air is supplied to the air cylinder 221 by an electric compressor, and the rod 221B of the air cylinder 221 is expanded from the shortened state. As a result, the backing plate 222 is pushed by the rod 221B of the air cylinder 221, and rotates in the direction of standing up from the first end 222A. Then, with such a rising operation of the patch plate 222, the second end 222B of the patch plate 222 can push up the floating part 4 while contacting the back surface 43 of the floating part 4. In other words, the rescue object 3 can be rescued by pushing up the floating section 4 from the initial depth toward the liquid surface using the cylinder lifting device 220 to levitate the rescue object 3 from the liquid. In addition, although the configuration example of the cylinder elevating device 220 shown in FIG. 7 employs a configuration in which the floating section 4 is operated via the backing plate 222, the present invention is not limited to this. For example, the floating section 4 may be directly operated by the rod 221B of the air cylinder 221.

[Device configuration]
FIG. 8 is a side view showing the structure of a rescue device according to a third modification of the second embodiment. Hereinafter, a rescue device 1B3, which is a third modification of the rescue device according to the second embodiment, will be described using FIG. 8. In the description of the modified example, the differences from the rescue device 1B explained in FIG. 5 will be mainly explained, and detailed descriptions of the same points as the rescue device 1B will be omitted. In Modification 3, an example will be described in which a drive device is configured by a lifting device (hereinafter simply referred to as a "reciprocating device") 230 that converts rotational motion into reciprocating motion.

The reciprocating device 230 includes a motor 231, a gear 232, an arm assembly 233 including a pair of arms, a rail 234, and the like. In this modification, the motor 231 is fixed to the bottom wall 21 (liquid bottom) of the bathtub 2. The gear 232 is used by meshing with a gear attached to the motor 231. Further, the motor 231 and the gear 232 are used at a gear ratio that allows rotational motion to be converted into reciprocating motion. The arm assembly 233 includes a long arm 233A and an arm 233B, and is an assembly in which the longitudinal center portions of the

arms

233A and 233B are pivotally connected to each other so that the arms 233A and the arm 233B intersect. Arm assembly 233 is pivotable about pivot portion 233C. In the arm assembly 233, a first end 233A1 of the arm 233A is fixed to the center of the gear 232, and a first end 233B1 of the arm 233B slides along a slide rail 21C formed on the bottom wall 21 of the bathtub 2. It is possible to move. Further, the second end 233A2 of the arm 233A and the second end 233B2 of the arm 233B are slidably fixed to a rail 234 installed on the back surface 43 of the floating section 4. However, the mode used in the reciprocating device 230 is one example, and is not limited.

[motion]
In the rescue device 1B3 according to this modification, the reciprocating device 230 is activated when rescuing the rescue target 3. That is, the motor 231 is operated and the gear 232 is rotationally driven. As a result, the arm 233A fixed to the gear 232 stands up. Arm 233A and arm 233B in arm assembly 233 are pivotally connected at pivot joint 233C, and first end 233B1 of arm 233B is slidable along slide rail 21C. Therefore, in conjunction with the rising motion of arm 233A, arm 233B pivots about pivot portion 233C relative to arm 233A. By operating the arm assembly 233 as described above, the arm assembly 233 can raise the back surface 43 of the floating section 4 while pushing it up. As a result, the rescue target 3 can be floated toward the liquid surface by the floating section 4 and rescued. In addition, in this modification, since the second end 233A2 of the arm 233A and the second end 233B2 of the arm 233B are slidable on the rail 234 of the floating section 4, when the reciprocating device 230 is operated, the levitation The portion 4 can be raised while being maintained in an attitude generally parallel to the liquid level.

In addition, in the rescue devices according to each of the embodiments described above, an example has been described in which electrical energy is used as a power source for operating the drive device, but the present invention is not limited to this, and for example, the drive device may be operated manually. It may be activated.

Not limited to each of the embodiments described above, the rescue device of the present disclosure is partially or entirely fixed to the liquid storage area, and whether or not there is a rescue target in the liquid storage area. Regardless, it is permanently attached to the liquid storage area. In this case, the direct fixation means that the drive device or the fixing part of the rescue tool is fixed by contacting the member that defines the liquid storage area, as exemplified by the rescue devices 1A, 1A1, 1B, and 1B1. It shows the state of being. In addition, the indirect fixing mode refers to a state where the fixing part of the drive device or the rescue tool is fixed without making direct contact with the member defining the liquid storage area, as exemplified by the rescue device 1A2. ing. However, the fixing manner in each of these embodiments is merely an example, and the present invention is not limited thereto.

In each of the above-described embodiments and modified forms of each embodiment, by fixing the drive device and rescue equipment to a raft-shaped object, etc. that floats on the liquid surface of the liquid storage area, a part of the liquid storage area can be removed. It is also possible to adopt a mode in which the rescue device can be used only for

<Automated equipment>
Next, for each of the rescue devices described above, an automated device for detecting drowning of the rescue target 3 and automatically operating the drive device will be described. Here, an example will be described in which the automated device is applied to the rescue device 1A described in the first embodiment, but it may also be applied to the rescue device 1B according to the second embodiment.

[Device configuration]
FIG. 9 is a schematic configuration diagram illustrating the automation device 90. As shown in FIG. The automation device 90 shown in FIG. 9 includes a detection sensor 91, a control unit 92, a warning light 93, an audio notification siren 94, and a monitor (display device) 95. The detection sensor 91 is a sensor for detecting drowning of the rescue target 3. The control unit 92 is a control computer that receives a signal from the detection sensor 91 and determines whether the rescue target 3 is drowning in the liquid storage area 2A based on the detection result of the detection sensor 91. The control unit 92 is connected to the winding device 100 (drive device), warning light 93, voice notification siren 94, etc. via wire or wireless. The warning light 93, the audio notification siren 94, and the monitor 95 are a notification device (notification unit) for notifying the surroundings of an abnormality when an abnormality occurs in the rescue target 3, such as drowning in the liquid storage area 2A.

[motion]
The control unit 92 determines whether the rescue target 3 is drowning in the liquid storage area 2A based on the detection result of the detection sensor 91. When the control unit 92 determines that the rescue target 3 is drowning in the liquid storage area 2A, the control unit 92 activates the hoisting device 100 (drive device) of the rescue device 1A to raise the flotation unit 4 toward the liquid surface. Rescue 3. At this time, the control unit 92 activates the warning light 93, the audio notification siren 94, etc., to notify the surroundings that the rescue target 3 is drowning. The control unit 92 also causes a display indicating that the rescue target 3 has drowned to be displayed on the screen of the monitor 95. At this time, the speaker of the monitor 95 may output a voice to the effect that the rescue target 3 has drowned. Note that the installation location of the warning light 93, audio notification siren 94, monitor 95, etc. as a notification unit is not particularly limited, and may be installed in a location other than the bathroom (for example, in another room). Further, the control unit 92 may be connected to the Internet, for example, and when the rescue target 3 drowns, it may transmit the information to a specific user terminal. Note that the control unit 92 can determine whether or not the rescue target 3 is drowning in the liquid storage area 2A by performing data processing on the detection signal obtained from the detection sensor 91 using an appropriate algorithm.

Further, the control unit 92 may determine that the rescue target 3 has escaped the drowning state based on the detection result of the detection sensor 91 after the hoisting device 100 (drive device) starts operating. When the rescue subject 3 comes out of a drowning state, such as when the head of the rescue subject 3 rises above the liquid surface of the liquid storage area 2A, the control unit 92 stops the hoisting device 100 (drive device) of the rescue device 1A. Good too. Further, the hoisting device 100 (drive device) may be operated and stopped manually. Further, a second detection sensor for determining whether the rescue target 3 has been sufficiently lifted from the liquid storage area 2A may be provided separately from the detection sensor 91. In this case, after the hoisting device 100 (drive device) starts operating, if the second detection sensor detects that the rescue target 3 has escaped from drowning, the control unit 92 controls the hoisting device 100 (drive device). ) will be stopped. The control unit 92 performs data processing on the detection signals obtained from the detection sensor 91 and the second detection sensor using an appropriate algorithm to determine whether the rescue target 3 has escaped from a drowning state (i.e., It is possible to determine whether or not the rescue of the rescue target 3 has been completed. Furthermore, in the case of using two hoisting devices 100, as exemplified by the rescue device 1A1 shown in FIG. The hoisting device 100 on the side where the head of the rescue target 3 is located may be activated preferentially.

Note that the automation device 90 does not need to include a warning light 93, an audio notification siren 94, a monitor 95, or other notification units, or may include only a part of them.

Although the embodiments according to the present disclosure have been described above, each aspect disclosed in this specification can be combined with any other feature disclosed in this specification.
