1A to 1D are explanatory diagrams of the conveying device 1. FIG. 1A is a left side view, FIG. 1B is a top view, FIG. 1C is a right side view, and FIG. 1D is a bottom view. FIG. 2 is an explanatory diagram of the carrier 1 in an open state. FIG. 3 is an explanatory diagram of the carrier device 1 in an open state with a person in need of rescue accommodated therein. 4A and 4B are explanatory diagrams of the transport device 1 in a closed state with a person in need of rescue accommodated therein. Note that FIG. 4A is an explanatory diagram of the conveying device 1 in a state before the tightening belt 51 is tightened. FIG. 4B is an explanatory diagram of the conveying device 1 with the tightening belt 51 tightened. FIG. 5 is an explanatory diagram of how a person in need of rescue accommodated in the carrier 1 is transported underwater.

Hereinafter, as shown in FIGS. 1A to 1D, each direction will be defined and explained. The height direction of the person requiring rescue when accommodated in the accommodation body 10 is called the "longitudinal direction", and the side of the top of the head viewed from the person requiring rescue is called the "parietal side" or "head side". The side is called the "toe side" or "foot side". In addition, the left-right direction of the rescued person when the rescued person is accommodated in the housing body 10 facing up is called the "left-right direction", the left side of the rescued person is called the "right side", and the right side of the rescued person is called the "left side". ” (The right side is called the “right side” and the left side is called the “left side” when viewed from the rescuer facing the rescuer). It should be noted that even when the container 10 does not contain a person requiring rescue, when explaining each part of the carrying device 1, the top side (or head side), the toe side (or foot side), the right side, the left side, etc. sometimes called Also, the "vertical direction" is defined along the vertical direction, the upper side in the vertical direction is called "upper", and the opposite side is called "lower".

The transport device 1 is a device used for transporting a person in need of rescue underwater. Here, in order to rescue a person in need of rescue left behind on board a capsized ship, a rescuer (divers) accommodates the person in need of rescue in the carrier 1 inside the ship (see FIGS. 4A and 4B), and the carrier 1 is assumed to be used to transport a rescuer in water (see FIG. 5). However, the conveying device 1 is not limited to rescuing a person in need of rescue from a capsized ship, and can be used for conveying a person in need of rescue in water for other purposes. Also, here, it is assumed that a child (a person with a height of about 130 cm; a person under the fourth grade of elementary school) whose face does not come into close contact with the face is a person requiring rescue. However, the person requiring rescue is not limited to a child, and may be an adult.

The conveying device 1 has a container 10 and a vent valve 21 .

The accommodation body 10 is a member for accommodating a person requiring rescue. The container 10 is a member having an elongated container space in the longitudinal direction. The container 10 can accommodate the cylinder 31 together with the person requiring rescue. The cylinder 31 and the respiratory apparatus 30 including the cylinder 31 will be described later.

The container 10 is configured to be openable and closable. The container 10 has a body portion 11 and a lid portion 12 . The body part 11 is a part that constitutes an accommodation part that accommodates a person requiring rescue. The lid portion 12 is a portion that closes the body portion 11 . By opening the lid portion 12, the main body portion 11 can be opened. Here, the main body part 11 and the lid part 12 are attached to the left side of the container 10 (the right side of the person requiring rescue). is configured to allow the opening of However, the lid portion 12 may be configured so that it can be opened from the opposite left and right sides, or it may be configured so that the lid portion 12 can be opened from the head side or the foot side of the person requiring rescue. Also, the lid portion 12 may be detachable from the main body portion 11 . The containing body 10 is configured in a bag shape (a shape in which only the mouth portion can be opened), and the containing body 10 is configured so that the rescuer-requiring person can enter the inside of the containing body 10 through the mouth portion of the bag. can be However, if the body portion 11 can be opened widely by opening the lid portion 12, the work of accommodating the person requiring rescue in the accommodation body 10 is facilitated.

The container 10 is configured to be openable and closable by a waterproof fastener 13 . As shown in FIGS. 1A and 1C, the waterproof fastener 13 is provided on the side surface of the container 10 along the outer circumference. The waterproof fastener 13 can close the gap between the body portion 11 and the lid portion 12 , and can prevent water from entering the container 10 . However, the container 10 that can be opened and closed without using the waterproof fastener 13 may be configured as long as the gap between the main body portion 11 and the lid portion 12 can be waterproofed.

The container 10 is made of a flexible waterproof sheet. Since the container 10 is made of a flexible member, the container 10 can be deformed. Thereby, as will be described later, when water pressure is applied to the container 10, the volume of the container 10 can be reduced. In addition, since the container 10 is made of a waterproof sheet, it is possible to prevent water from entering the container 10 .

The vent valve 21 (21A, 21B) is a valve capable of discharging the air inside the container 10. As shown in FIG. The vent valve 21 discharges air from the inside of the container 10 to the outside while preventing water from flowing into the container 10 from the outside. The vent valve 21 is composed of, for example, a one-way valve. The vent valve 21 is actuated by the pressure difference caused by the water pressure exerted on the container 10 when the carrier 1 is drawn into the water. The vent valve 21 operates at a relatively low pressure of about 0.015 MPa, for example (air is discharged from the inside of the container 10 to the outside with a pressure difference of about 0.015 MPa). When water pressure is applied to the container 10 , the air inside the container 10 is discharged to the outside of the container 10 . As a result, the capacity of the container 10 can be reduced, the buoyancy of the container 10 can be reduced, and the transport of the rescuer in water becomes easier.

The vent valve 21 has a lock button (not shown). When the lock button is released (released state), air can be discharged from the vent valve 21 . When the lock button is pressed (locked state), air discharge from the vent valve 21 is stopped. Since the vent valve 21 has a lock button, it can be switched between a released state and a locked state. As a result, the rescuer can adjust the buoyancy of the container 10 and adjust the balance of the buoyancy of the container 10 by operating the lock button, thereby facilitating the transportation of the rescuer in water. Become.

As shown in FIGS. 1A to 1D, the vent valve 21A is arranged on the parietal side of the person requiring rescue. As a result, as shown in FIG. 5, when the rescuer's head is turned up underwater, the air accumulated in the rescuer's head can be discharged from the vent valve 21A. Easier to transport.

As shown in FIG. 1B, two vent valves 21A are arranged laterally apart on the parietal side of the person requiring rescue. By arranging the two vent valves 21A apart in the left-right direction of the container 10 in this way, the balance of the buoyancy of the container 10 in the left-right direction can be adjusted. It should be noted that the two vent valves 21A arranged separately in the left-right direction of the container 10 may not be arranged on the parietal side of the person requiring rescue. However, if two vent valves 21A are arranged separately in the left-right direction on the parietal side of the person requiring rescue, the two vent valves 21A are used to vent the air accumulated in the head of the person requiring rescue. It is possible to both discharge from the valve 21A and adjust the balance of the buoyancy of the container 10 in the horizontal direction.

As shown in FIGS. 1A-1C, another vent valve 21B is located on the toe side of the rescuer. As a result, the air that accumulates on the foot side of the person requiring rescue can be discharged from the vent valve 21B, making it easier to turn the head of the person requiring rescue underwater.

The containing body 10 can contain a cylinder 31 (see FIG. 3). The cylinder 31 is a supply source of air to be supplied to a rescuer. The cylinder 31 is sometimes called a tank. By supplying air from the cylinder 31 , the person requiring rescue can breathe inside the container 10 . Here, it is assumed that a cylinder 31 with an internal volume of 4 L (liters) to 10 L (liters) is accommodated in the container 10 . For example, when rescuing a rescuer from a capsized ship, it is assumed that the rescue time is about 10 minutes, and it is sufficient to supply air to the rescuer for about 15 minutes. Accommodate at 10. On the other hand, when rescuing a person in need of rescue from a sunken ship, a 10 L (liter) cylinder 31 is accommodated in the container 10 because the rescue time is longer than in the case of a capsized ship.

The container 10 has a cylinder fixing portion 41 (see FIGS. 2 and 3). The cylinder fixing part 41 is a part for fixing the cylinder 31 inside the container 10 . The cylinder fixing portion 41 is provided on the bottom surface of the main body portion 11 of the container 10 . Here, the cylinder fixing part 41 is constituted by a belt, the central part of which is fixed to the container 10, hook-and-loop fasteners are provided at both ends of the belt, and the belt is wrapped around the outer periphery of the cylinder 31. The cylinder 31 can be fixed to the container 10 by fastening the ends of the belt with hook-and-loop fasteners. However, as long as the cylinder fixing part 41 can fix the cylinder 31, the structure other than the belt may be used. Although a buckle may be provided at the end of the belt instead of the hook-and-loop fastener, damage to the cylinder 31 can be suppressed by adopting a flexible hook-and-loop fastener. Further, here, the cylinder fixing portion 41 is composed of a plurality of (here, three) belts attached to the main body portion 11 . However, the number of belts constituting the cylinder fixing portion 41 may be plural other than three, or may be singular (one). Since the container 10 has the cylinder fixing portion 41, the position of the cylinder 31 can be stabilized when the rescuer is transported. However, the container 10 may not have the cylinder fixing portion 41 .

As shown in FIG. 3, the cylinder fixing part 41 can fix the cylinder 31 between the legs of the person requiring rescue. For this reason, the cylinder fixing portion 41 is arranged on the foot side of the container 10 and is also arranged in the central portion of the container 10 in the left-right direction. By fixing the cylinder 31 between the legs of the person requiring rescue, the longitudinal dimension of the container 10 can be shortened, and the position of the cylinder 31 can be stabilized during transportation of the person requiring rescue. In particular, when water pressure is applied to the container 10, the cylinder 31 is sandwiched between the feet of the person requiring rescue, so the position of the cylinder 31 can be stabilized during transportation of the person requiring rescue. Note that the cylinder fixing part 41 does not have to fix the cylinder 31 between the legs of the person requiring rescue. For example, the cylinder 31 may be fixed to either the left or right side of the person requiring rescue. However, in this case, since the center of gravity is biased to either the left or the right, the balance between the left and right becomes poor when transporting the rescuer. Further, for example, the cylinder 31 may be fixed ahead of the feet of the person requiring rescue. However, in this case, the longitudinal dimension of the container 10 is increased.

As shown in FIG. 3, the cylinder fixing portion 41 can fix the cylinder 31 with the first stage portion 31A directed toward the toes. If the cylinder 31 is arranged so that the first stage portion 31A of the cylinder 31 is located on the crotch side of the person requiring rescue, the first stage portion 31A and the crotch of the person requiring rescue interfere with each other, which may cause malfunction of the cylinder 31. , may cause discomfort to the person requiring rescue. On the other hand, by fixing the cylinder 31 with the first stage portion 31A directed toward the toe side by the cylinder fixing portion 41, interference between the first stage portion 31A and the crotch of the person requiring rescue can be prevented. However, the cylinder fixing portion 41 may fix the cylinder 31 in the opposite direction ((the direction in which the first stage portion 31A faces the crotch side of the person requiring rescue).

As shown in FIG. 3, among the three belts forming the cylinder fixing portion 41, the belt on the toe side is wider than the other belts. As a result, when the cylinder fixing portion 41 fixes the cylinder 31 with the first stage portion 31A facing the toe side, the first stage portion 31A can be covered with the wide belt (belt on the toe side). . By covering the first stage portion 31A with the cylinder fixing portion 41 in this manner, the first stage portion 31A can be protected. However, the toe-side belt does not have to be wider than the other belts. Further, the cylinder fixing portion 41 does not have to be configured to cover the first stage portion 31A.

The container 10 can accommodate a residual pressure gauge 32, a regulator 33, and a mask 35 together with the cylinder 31 (see FIG. 3). Note that the cylinder 31, the residual pressure gauge 32, the regulator 33, and the mask 35 constitute a respiratory apparatus 30 for maintaining the respiration of the person requiring rescue. In other words, the carrier 1 further includes a respiratory apparatus 30 , and the container 10 can accommodate the respiratory apparatus 30 . By housing the respiratory apparatus 30 in the container 10, the breathing of the rescuer accommodated in the container 10 can be ensured.

A residual pressure gauge 32 (see FIG. 3) measures the residual pressure of the cylinder 31 . The residual pressure gauge 32 is connected to the first stage portion 31A of the cylinder 31 via a hose (high pressure hose).

The container 10 has a residual pressure gauge holding portion 42A (see FIGS. 2 and 3). The residual pressure gauge holding portion 42A is a portion that holds the residual pressure gauge 32 inside the container 10 . Here, the residual pressure gauge holding portion 42A is configured in a bag shape (pocket shape). The residual pressure gauge holding portion 42A is provided inside the lid portion 12 of the container 10 . Since the container 10 has the residual pressure gauge holding portion 42A, the position of the residual pressure gauge 32 can be stabilized during transportation of the person requiring rescue.
Further, the container 10 has a residual pressure gauge fixing portion 42B. The residual pressure gauge fixing portion 42B is a portion that fixes the residual pressure gauge 32 while being held by the residual pressure gauge holding portion 42A. The residual pressure gauge fixing portion 42B is provided inside the lid portion 12 of the container 10 . Here, the residual pressure gauge fixing portion 42B is configured with a hook-and-loop fastener, and the residual pressure gauge 32 is fixed to the residual pressure gauge holding portion 42A by fixing a hose (high-pressure hose) extending from the residual pressure gauge 32 with the hook-and-loop fastener. Since the container 10 has the residual pressure gauge fixing portion 42B, the position of the residual pressure gauge 32 can be stabilized during transportation of the person requiring rescue. Instead of fixing the hose extending from the residual pressure gauge 32, the residual pressure gauge fixing portion 42B may directly fix the residual pressure gauge 32 to the residual pressure gauge holding portion 42A. In addition, the residual pressure gauge fixing portion 42B may not be provided on the container 10 .

The container 10 has a window (residual pressure confirmation window 42C) for confirming the residual pressure gauge 32 (see FIGS. 1B, 4A and 4B). The residual pressure confirmation window 42C is made of a transparent member. Since the container 10 has the residual pressure confirmation window 42C, the rescuer can confirm the residual pressure gauge 32 arranged inside the container 10 through the residual pressure confirmation window 42C. The residual pressure confirmation window 42C is provided in the lid portion 12 of the container 10, and is provided in a portion where the residual pressure gauge holding portion 42A is provided. In other words, the residual pressure gauge holder 42A is provided behind the residual pressure confirmation window 42C (inside the container 10). As a result, it is possible to prevent the residual pressure gauge 32 from coming off the residual pressure confirmation window 42C, so that the residual pressure gauge 32 can be stably confirmed when the person requiring rescue is transported.

A regulator 33 (see FIG. 3) regulates the air pressure. Regulator 33 is sometimes called a second stage. The regulator 33 is connected to the first stage portion 31A of the cylinder 31 via a hose (medium pressure hose).

The regulator 33 is configured to supply air from the cylinder 31 at a predetermined flow rate. Here, the regulator 33 is configured to supply 10 L (liter) of air per minute. However, the flow rate of air supplied from the regulator 33 is not limited to 10 L/min. The regulator 33 is configured to supply a predetermined flow rate of air at the same pressure as the water depth (environmental pressure) where the rescuer is present (for this reason, the deeper the water depth, the more air consumption of the cylinder 31). will increase). By supplying air at a predetermined flow rate from the regulator 33, it becomes easier to ensure the breathing of the person requiring rescue even in a situation where the person requiring rescue cannot wear the mask.

The container 10 has a regulator holding portion 43A (see FIGS. 2 and 3). The regulator holding portion 43A is a portion that holds the regulator 33 inside the container 10 . The regulator holding portion 43A is provided inside the lid portion 12 of the container 10 . Here, the regulator holding portion 43A is configured in a bag shape (pocket shape). Since the container 10 has the regulator holding portion 43A, the position of the regulator 33 can be stabilized during transportation of the person requiring rescue.
Further, the container 10 has a regulator fixing portion 43B. The regulator fixing portion 43B is a portion that fixes the regulator 33 while being held by the regulator holding portion 43A. The regulator fixing portion 43B is provided inside the lid portion 12 of the container 10 . Here, the regulator fixing portion 43B is made of a hook-and-loop fastener, and the regulator 33 is fixed to the regulator holding portion 43A by fixing the shut-off valve 34 (described later) extending from the regulator 33 with the hook-and-loop fastener. Since the container 10 has the regulator fixing portion 43B, the position of the regulator 33 can be stabilized during transportation of the person requiring rescue. The regulator fixing portion 43B may fix the regulator 33 to the regulator holding portion 43A by fixing a hose (medium pressure hose) extending from the regulator 33 instead of fixing the shutoff valve 34 (described later). Alternatively, the regulator 33 may be directly fixed to the regulator holding portion 43A. Further, the regulator fixing portion 43B may not be provided on the container 10 .

The container 10 has a window (regulator confirmation window 43C) for confirming the regulator 33 (see FIGS. 1B, 4A and 4B). 43 C of regulator confirmation windows are comprised by the transparent member. Since the container 10 has the regulator confirmation window 43C, the rescuer can operate the regulator 33 arranged inside the container 10 while confirming the regulator 33 through the regulator confirmation window 43C (for example, the container 10 The purge button of the regulator 33 can be operated through the flexible waterproof sheet of the . 43 C of regulator confirmation windows are provided in the cover part 12 of the container 10, and are provided in the site|part in which the regulator holding|maintenance part 43A was provided. In other words, the regulator holding portion 43A is provided behind the regulator confirmation window 43C (inside the container 10). As a result, when the person requiring rescue operates the regulator 33, it is possible to prevent the regulator 33 from coming off the regulator confirmation window 43C.

As shown in FIG. 3, a shutoff valve 34 is provided between the regulator 33 and a hose (medium pressure hose). The shutoff valve 34 is a member (control valve) that opens and closes the air flow path. By providing the shut-off valve 34, the air supply from the regulator 33 and cutoff can be manually switched. For example, when the supply of air from the regulator 33 is unnecessary, the consumption of air in the cylinder 31 can be suppressed by closing the shut-off valve 34 to shut off the flow path. Note that the shutoff valve 34 may not be provided. However, the provision of the shut-off valve 34 facilitates the work of the rescuer, as will be described later.

The mask 35 (see FIG. 3) is a member that is attached to the rescuer to supply air while covering the mouth and nose of the rescuer. Mask 35 is connected to regulator 33 via a tube. Therefore, air is supplied to the mask 35 from the regulator 33 at a predetermined flow rate. By using the mask 35, air can be supplied to the rescuer's face (particularly around the mouth and nose) even if the container 10 is subjected to water pressure during transportation of the rescuer. In addition, by supplying the mask 35 with air from the regulator 33 at a predetermined flow rate, it becomes easier for the person requiring rescue to breathe even when the person cannot wear a facepiece.

FIG. 6 is an explanatory diagram of the mask 35. As shown in FIG.
The mask 35 has a mask body 35A, a reservoir 35B, and a connecting portion 35C. That is, the mask 35 is a mask with a reservoir. The mask main body 35A is a member that covers the mouth and nose of the rescuer. A one-way valve is provided in the mask body 35A, and the air (exhalation of the person requiring rescue) in the mask body 35A can be discharged outside from the one-way valve. The reservoir 35B is a member (bag) that stores air supplied from the regulator 33 . The connecting portion 35C is a member arranged between the mask main body 35A and the reservoir 35B, and is a tubular (branched tubular) member that forms a flow path. The connecting portion 35C can supply the air stored in the reservoir 35B to the mask main body 35A. A one-way valve may be provided between the connecting portion 35C and the mask main body 35A. A tube connected to the regulator 33 is connected to the connecting portion 35C. The air supplied from the tube to the connection part 35C is temporarily stored in the reservoir 35B, and when the rescuer inhales, the air in the reservoir 35B is supplied to the inside of the mask body 35A through the connection part 35C. become. Also, part of the air supplied from the tube may be supplied to the inside of the mask main body 35A via the connecting portion 35C. By using a mask with a reservoir, it becomes easier to keep the rescuer breathing. In particular, under conditions where air is supplied from the regulator 33 at a predetermined flow rate, it is effective to use a mask with a reservoir to maintain the respiration of the person requiring rescue. However, the mask 35 may not be a mask with a reservoir. Also, the mask 35 may not be used, and for example, a face piece may be used instead of the mask 35 .

The container 10 has an inflator valve 44 (see FIGS. 1A-1C). The inflator valve 44 is a valve capable of supplying air from the outside of the container 10 to the inside. The inflator valve 44 can supply air only in one direction from the outside to the inside of the container 10 while preventing water from flowing into the container 10 . In an emergency (e.g. when the cylinder 31 is low on air), the rescuer can supply air to the container 10 via the inflator valve 44 from their own air tank or from a spare air cylinder. . The inflator valve 44 is provided on the lid portion 12 of the container 10 . This makes it easier for the rescuer to supply air to the container 10 via the inflator valve 44 from their own air tank. However, the inflator valve 44 may not be provided on the lid portion 12 . Incidentally, if it is possible to supply a sufficient amount of air to the containing body 10 via the inflator valve 44, it is possible not to contain the cylinder 31 in the containing body 10. FIG. The container 10 may not have the inflator valve 44 . However, by providing the container 10 with the inflator valve 44, the person requiring rescue can be transported underwater more safely.

The transport device 1 further comprises a tightening belt 51 (see FIGS. 1A-1D).
The tightening belt 51 is a member (belt) that tightens the outer circumference of the container 10 . The container 10 is composed of a flexible sheet, and by tightening the outer periphery of the flexible container 10 with a tightening belt 51, the volume of the container 10 can be reduced (see FIG. 4B). Since the buoyancy of the container 10 can be reduced by reducing the volume of the container 10, it becomes easier to transport the person in need of rescue underwater.

An end of the tightening belt 51 is provided with a fastener 52 (see FIG. 1C). The fastener 52 is a member for annularly fastening the tightening belt 51 . For example, the fastener 52 is configured with a buckle. By pulling the end portion of the tightening belt 51 while fixing the tightening belt 51 in a loop with the fastener 52, the outer circumference of the container 10 can be tightened by the tightening belt 51 (see FIG. 4B). By removing the fastener 52, the annular tightening belt 51 can be released, whereby the container 10 can be opened. As shown in FIG. 1C , when the tightening belt 51 is annularly fastened by the fastener 52 , the fastener 52 is arranged near the waterproof fastener 13 . By arranging the fastener 52 near the waterproof fastener 13, the work of the rescuer (opening and closing the waterproof fastener 13, attaching and detaching the fastener 52, pulling the end of the tightening belt 51 (tightening the container 10) work), etc.) becomes easier.

The tightening belt 51 is attached to the container 10 . Here, the container 10 is provided with a belt insertion portion 55 (FIGS. 1B and 1D), and the tightening belt 51 is attached to the container 10 by passing the tightening belt 51 through the belt insertion portion 55. It is The belt insertion portion 55 is a loop-shaped portion through which the tightening belt 51 is inserted. If the tightening belt 51 is attached to the container 10, the tightening belt 51 will not separate from the container 10, which is convenient. However, the tightening belt 51 may be a member separated from the container 10 .

It is desirable that the size of the fastener 52 (buckle; see FIG. 1C) is such that the belt insertion portion 55 cannot be inserted. This can prevent the tightening belt 51 from coming off the belt insertion portion 55 . Even if the size of the fastener 52 is large enough to allow the belt insertion portion 55 to pass through, if the width of the fastener 52 is larger than the width of the tightening belt 51, the fastener 52 can be inserted into the belt insertion portion 55. can be made difficult to come off.

It should be noted that the fastener 52 of the tightening belt 51 does not have to consist of a buckle. For example, a hook-and-loop fastener may be employed as the fastener 52 of the tightening belt 51 . However, by constructing the fastener 52 of the tightening belt 51 with a buckle, the fastener 52 becomes difficult to come off when the rescuer is transported.

As shown in FIGS. 1A to 1D, the container 10 has a plurality of tightening belts 51 (three in this case). However, the number of tightening belts 51 may be plural other than three, or may be singular (one).

The tightening belt 51 is arranged closer to the foot than the head of the person requiring rescue (see FIGS. 4A and 4B). In other words, the tightening belt 51 arranged closest to the head is arranged closer to the foot than the head of the person requiring rescue. Here, the tightening belt 51 is arranged closer to the foot than the window 63 (described later). By arranging the tightening belt 51 closer to the feet than the head of the person requiring rescue, even when the container 10 is tightened by the tightening belt 51 (the tightening belt 51 reduces the volume of the container 10). ), it is possible to secure a space around the rescued person's head. By increasing the volume of the head side of the container 10 while reducing the volume of the container 10 on the foot side, it is easy to transport the rescuer in the water with the person's head up. Become.

As shown in FIGS. 4A and 4B, the tightening belt 51 arranged on the foot side can tighten the cylinder 31 and the person requiring rescue (specifically, the foot of the person requiring rescue) over the container 10 . As a result, the posture of the cylinder 31 and the person requiring rescue can be stabilized during transport of the person requiring rescue. In particular, when the cylinder 31 is fixed between the rescuer's legs, the tightening belt 51 clamps the cylinder 31 and the rescuer's legs over the container 10, thereby preventing the cylinder 31 from being transported by the rescuer. position can be stabilized.

The container 10 also has a handle 61 , a weight mounting portion 62 and a window 63 .

A handle 61 (see FIGS. 1A to 1D) is a portion for gripping the container 10 . By providing the container 10 with the handle 61, the person in need of rescue can be easily transported underwater (see FIG. 5). One handle 61 is provided on each of the top of the head and the toe of the container 10 . This makes it easier to adjust the vertical posture of the rescuer when transporting the rescuer underwater (for example, transporting the rescuer with the rescuer's head up in the water). easier). Two handles 61 are provided on each of the left and right side surfaces of the container 10 . This makes it easier to adjust the vertical posture of the person requiring rescue from the side of the container 10 when transporting the person requiring rescue underwater.

The color of handle 61 is preferably different from the color of container 10 . This makes it easier for the rescuer to recognize the portion of the container 10 to be gripped. It is more desirable that the color of the handle 61 is brighter than the color of the container 10 . For example, the container 10 is black, while the handle 61 is yellow (or orange). Since the container 10 needs to be made of a high-strength waterproof sheet, the options for the color of the container 10 are narrowed. can be. On the other hand, since the handle 61 has a wider range of colors to choose from than the container 10, it is easy to use a color that is brighter than the container 10. Since the person in need of rescue may be transported in dark water, the color of the handle 61 is lighter than that of the container 10, so that the person in need of rescue can be transported in water more safely.

The aforementioned tightening belt 51 is desirably inserted between the container 10 and the handle 61 (see FIGS. 1A to 1D). Thereby, the part tightened by the tightening belt 51 can be gripped. Since the shape of the containing body 10 is stable at the portion tightened by the tightening belt 51 (because the sheet constituting the containing body 10 does not wobble), the tightening belt 51 is inserted between the containing body 10 and the handle 61. By doing so, it becomes easier to transport the rescuer in the water. However, the tightening belt 51 does not have to be inserted between the container 10 and the handle 61 . Moreover, the container 10 may not have the handle 61 .

The weight mounting portion 62 (see FIGS. 1A, 1C, and 1D) is a portion for mounting a weight. Here, the weight attachment portion 62 is configured in a bag shape (pocket shape) capable of accommodating the weight. However, as long as the weight can be attached to the container 10, the weight attaching portion 62 does not have to be configured in the shape of a bag. By providing the container 10 with the weight mounting portion 62, the buoyancy of the container 10 can be adjusted. The weight mounting portion 62 is provided on the outer surface of the container 10 . This allows the rescuer to adjust the weight when transporting the rescuer in water (see FIG. 5). The container 10 has a plurality of weight attachment portions 62 . Accordingly, by adjusting the weights attached to the respective weight attachment portions 62, the balance of the buoyancy of the container 10 can be adjusted. The weight mounting portion 62 may be fixed to the container 10, or may be detachable from the container 10 by, for example, a hook-and-loop fastener. Note that the container 10 may not have the weight mounting portion 62 .

The window 63 (see FIG. 1B) is a transparent part for checking the rescuer's face. As shown in FIGS. 4A and 4B , the window 63 is provided at a portion facing the face of the rescuer accommodated in the container 10 . The rescuer can check the condition of the person requiring rescue through the window 63 . Since the rescuer can also see the rescuer and the outside through the window 63, the container 10 having the window 63 can give the rescuer a sense of security. Note that the container 10 may not have the window 63 . However, by providing the container 10 with the window 63, the person requiring rescue can be transported underwater more safely.

The delivery device 1 may be provided with a head protector 70 (see Figures 2 and 3). The containing body 10 is configured to be able to contain the head protector 70 . The head protector 70 is a member that protects the head of the rescuer. The head protector 70 is a member also called a head immobilizer. The head protector 70 is attachable to and detachable from the container 10 . A hook-and-loop fastener is provided on the bottom surface inside the container 10 , and the head protector 70 can be fixed to the bottom surface inside the container 10 . By fixing the head protector 70 to the container 10, the posture of the person requiring rescue can be stabilized. Note that the container 10 may not include the head protector 70 . However, by providing the container 10 with the head protector 70, the person requiring rescue can be transported in water more safely.

The head protector 70 has a base portion 71 and a pair of support portions 72 . The base portion 71 is a plate-like member. The base portion 71 may also be called a base pad or base plate. The base portion 71 has tie belts 71A for fixing the head and chest of the person requiring rescue. The support portion 72 is a member that supports the temporal region of the person requiring rescue. By sandwiching the head of the person requiring rescue between the pair of support portions 72, the head of the person requiring rescue can be supported. The support portion 72 may be provided with ear holes for checking the ears of the person requiring rescue. The support portion 72 is detachable from the base portion 71 . Hook-and-loop fasteners are provided on the surface of the base portion 71 and the bottom surface of the support portion 72, so that the support portion 72 can be fixed to the base portion 71 by fitting it to the head of the person requiring rescue. It is also possible to use only the base portion 71 as the head protector 70 without using the support portion 72 .

As described above, the conveying device 1 according to this embodiment includes the container 10 and the vent valves 21 (21A, 21B). As a result, the air inside the container 10 is discharged from the vent valve 21 when water pressure is applied to the container 10, so that the volume of the container 10 can be reduced and the buoyancy of the container 10 can be reduced. , facilitating transport of a rescuer in water. In addition, as described below, when rescuing a survivor (person requiring rescue) using the transport device 1, while ensuring the breathing of the person requiring rescue accommodated in the container 10, extra air that acts as buoyancy is discharged from the exhaust valve 21, the conveying device 1 can be pulled into the water.

<Conveyance method>
Next, a transportation method using the transportation device 1 (a method of using the transportation device 1) will be described. Here, a case of rescuing survivors (persons requiring rescue) trapped in a capsized ship will be described.

First, the rescuer prepares the carrier 1. At this time, it is desirable that the breathing device 30 (the cylinder 31, the residual pressure gauge 32, the regulator 33 and the mask 35) is housed inside the container 10 in advance. This makes it easier for the rescuer to move to the person requiring rescue compared to carrying the container 10 and the breathing apparatus 30 separately. At this time, the cylinder 31 is fixed to the cylinder fixing portion 41, the residual pressure gauge 32 is fixed by the residual pressure gauge fixing portion 42B while being held by the residual pressure gauge holding portion 42A, and the regulator 33 is held by the regulator holding portion 43A. It is more desirable that the regulator fixing portion 43B fixes the regulator fixing portion 43B in the state of being held. This makes it easier for a rescuer to accommodate a rescuer inside the capsized ship. Moreover, a head protector 70 or the like may be accommodated inside the container 10 as necessary. Also, a member such as a blanket for keeping the person in need of rescue warm may be accommodated in the container 10 .
At this stage, it is desirable to open the cylinder 31 in the first stage portion 31A of the cylinder 31 and close the shut-off valve in advance. This point will be described later.

Next, the rescuer carries the carrier 1 and heads for the rescued person inside the capsized ship. It is desirable that the container 10 is tightened by the tightening belt 51 when the rescuer carries the carrier 1 in the water. As a result, the volume of the container 10 can be reduced, so that the rescuer can easily move the transport device 1 in the water.

After reaching the person in need of rescue inside the capsized ship, the rescuer deploys the container 10 inside the capsized ship where air remains, and accommodates the person in need of rescue in the main body 11 of the container 10. do. The rescuer places the container 10 on a horizontal surface as much as possible, lays the rescuer on his back in the opened container 10, and places the rescuer on the main body 11 of the container 10. accommodate. At this time, it is desirable for the rescuer to place the rescuer in the container 10 so as to bring the rescuer to the parietal side of the container 10 as much as possible. This makes it easier to reduce the volume of the container 10 during transportation. Also, at this time, the rescuer accommodates the rescuer in the container 10 with the cylinder 31 straddled over the rescuer so that the cylinder 31 is placed between the legs of the rescuer. In addition, the rescuer may use the head protector 70 to protect the head of the rescuer or wrap the rescuer in a blanket, if necessary. The rescuer may insert a blanket between the legs of the person requiring rescue and the cylinder 31 .

Also, the rescuer attaches the mask 35 to the rescuer. At this time, the rescuer operates the shutoff valve to open the shutoff valve 34 and start supplying air from the cylinder 31 . When the supply of air from the cylinder 31 is started, the regulator 33 supplies air at a predetermined flow rate (here, 10 L/min) to the mask 35 of the person requiring rescue. In addition, at the stage of preparing the carrier device 1, the supply of air from the cylinder 31 can be quickly started by closing the shut-off valve while opening the cylinder 31 in advance.

After accommodating the person requiring rescue in the body portion 11 of the accommodation body 10 , the rescuer closes the lid portion 12 and the waterproof fastener 13 . Thereby, the person requiring rescue is accommodated inside the accommodation body 10 . After accommodating the person requiring rescue inside the container 10 , the rescuer fastens the fastener 52 of the tightening belt 51 and pulls the end of the tightening belt 51 to secure the container 10 with the tightening belt 51 . Tighten the perimeter of the Thereby, the volume of the container 10 can be reduced. In addition, since the fastener 52 (buckle) is arranged in the vicinity of the waterproof fastener 13, the rescuer does not need to close the waterproof fastener 13, fasten the fastener 52, or tighten the end of the tightening belt 51. The operation of pulling (the operation of tightening the container 10) can be performed quickly.

Next, the rescuer pulls the carrier 1 containing the rescuer into the water. At this time, water pressure is applied to the container 10, and the air inside the container 10 is discharged through the vent valve 21 (21A, 21B). As a result, the capacity of the container 10 can be reduced, the buoyancy of the container 10 can be reduced, and the transport of the rescuer in water becomes easier. In this way, when rescuing a survivor (a person requiring rescue) using the conveying device 1, while ensuring the breathing of the person requiring rescue accommodated in the accommodation body, excess air that becomes buoyancy is discharged from the exhaust valve. It is possible to draw the conveying device 1 into the water while doing so. It is desirable for the rescuer to gradually pull the carrying device 1 into the water from the foot side of the person requiring rescue. As a result, since the water pressure is first applied to the foot side of the containing body 10, the volume of the foot side of the containing body 10 can be reduced first, and the rescue request is made with the head of the person requiring rescue in the water up. Easier to transport people.

A rescuer draws the carrier 1 containing the rescuer into the water, carries the rescuer under the water, and escapes from the capsized ship. When a person requiring rescue is transported underwater, air is supplied from the regulator 33 to the mask 35 at a predetermined flow rate inside the container 10, so that the person requiring rescue can secure breathing. In addition, even if a predetermined flow rate of air continues to be supplied to the interior of the container 10, the air inside the container 10 is discharged from the vent valve 21, so the buoyancy of the container 10 can be suppressed. In addition, by adjusting the attitude of the container 10, the rescuer can adjust the discharge of air from the vent valve 21, adjust the buoyancy of the container 10, and balance the buoyancy of the container 10. can be adjusted. Since the handle 61 is provided on the container 10, the rescuer can hold the handle 61 and adjust the vertical posture of the container 10 when transporting the person requiring rescue underwater. The exhaust of air from the air valve 21 can be regulated. The rescuer can adjust the buoyancy of the container 10 and the balance of the buoyancy of the container 10 by operating the lock button of the vent valve 21 and adjusting the weight of the weight mounting portion 62. can also

The rescuer can check the condition of the rescuer through the window 63 when transporting the rescuer in the water. In addition, the rescuer can check the residual pressure gauge 32 through the residual pressure confirmation window 42C when transporting the person in need of rescue underwater. In addition, when transporting a rescuer underwater, the rescuer is placed inside the container 10 through the flexible waterproof sheet of the container 10 while checking the regulator 33 through the regulator confirmation window 43C. A purge button of the regulator 33 can be operated. Also, in an emergency (e.g., when the remaining amount of air in the cylinder 31 is insufficient), the rescuer can supply air to the container 10 via the inflator valve 44 from his/her own air tank or a spare air blower. is.

After lifting the carrier 1 out of the water, the container 10 is unfolded and the person requiring rescue is lifted out of the container 10 . In addition, after the carrier 1 is lifted out of the water, the rescuer-required person may be loaded on the stretcher together with the container 10 in a state where the rescuer-required person is accommodated.

In the above description, a case of rescuing a rescuer trapped in a capsized ship has been described, but the method of using the carrier 1 is not limited to this. For example, when rescuing a person in need of rescue from a sunken ship, or in rescuing a person in need of rescue from a cave that requires diving, it is also possible to transport the person in need of rescue underwater using the above-mentioned transport equipment 1. is.
