The case body 12 is a housing case (housing) that houses device components such as the contracted float 14 and the expansion drive device 16 in an internal housing space and integrally forms a unit. In this reference example , the case body 12 is made of a material such as plastic, which is hard, lightweight, and water-impervious synthetic resin, and has a length (length × width) of about 10 cm × 6 cm and a thickness (depth) when viewed from the front. ) Is formed in a rectangular parallelepiped shape of about 3 cm. The case body 12 has a rectangular parallelepiped internal housing space closed by closing six surfaces of the front surface, the rear surface, the right side surface, the left side surface, the upper surface, and the lower surface with a flat plate-like outer plate portion. In addition, as for the case body 12, a corner | angular part is good in order to prevent injury. The shape of the case body may be, for example, any other shape such as a circular shape, an elliptical shape, a long round shape, a polygonal box shape of pentagon or more, or a cylindrical body such as a cylindrical body or a rectangular tubular body in front view. In the present reference example , the internal housing space of the case body 12 is vertically divided into two left and right portions at a substantially central position in the left and right directions when viewed from the front, and accommodates the float 14 on the right side when viewed from the front. The bag storage part 22 is provided, and the left side is provided side by side as a cylinder storage part 24 for storing a cylinder constituting the expansion drive device 16. Note that the internal space of the case body 12 may have any other divided structure such as a vertical or vertical division, and the floating bag and the cylinder may be accommodated in one space without being divided.

In this reference example , as shown in FIGS. 1, 3, and 6, the case body 12 is provided with an opening / closing portion that opens and closes a part of the outer plate portion. The air bag 14 is closed so as to be held, and is opened so as to inflate the bag 14 to the outside of the case body in an emergency. The opening / closing part is composed of a lid activation plate 18 constituting a part of the outer plate part of the case body 12. The lid activation plate 18 is installed in a substantially right half portion of the front side outer plate portion, and opens and closes the entire front side of the floating bag housing portion 22. The lid activation plate 18 is made of a plate member that is formed to be relatively large so that it can be operated by hand, and has a structure in which a hand can be easily applied to any part of the peripheral portion from the outside of the case body. That is, the lid activation plate 18 has a structure having the clue portions 19 at least at several places. In addition, a part of the case body 12 may be recessed or a part of the lid activation plate 18 may be protruded so that the hand can be easily put on by the clue when the lid activation plate 18 is opened. The lid activation plate 18 maintains the closed state in a normal state and protects the contracted float 14 accommodated in the case body while securely storing and holding it inside, while forcibly opening the lid from the outside. In this case, an expansion expansion path 26 to the outside of the case body of the floating bag 14 that is inflated by the opened opening is secured. That is, the opening of the case body 12 when the lid activation plate 18 is opened serves as an expansion expansion path 26 of the floating bag 14 to the outside of the case body. Further, as will be described later, the lid activation plate 18 constitutes an operating device 17 that activates the expansion driving device 16 when the lid is opened, and further, when the lid is opened, the expansion activation of the expansion driving device 16 and the floating bag 14 are performed. The starting and opening mechanism 29 is configured to simultaneously perform the expansion and expansion path securing. Because it is a structure that can be opened and closed freely with a lid activation plate as in this reference example , in order to expand and expand the bag to the outside of the case body, with a structure that keeps a part of the case body open at all times, or a material that is easy to tear Compared with the structure etc. which cover, the high reliability at the time of starting the damage prevention of the floating bag 14 accommodated in the case body 12, holding | maintenance of a storage state, and the expansion | swelling start of the floating bag outside the case body is realizable. As shown in FIG. 2, in this reference example , the lid activation plate 18 has, for example, a hinged door opening / closing structure that is opened by a pulling operation with respect to the case body 12. It pivots around a pivot shaft with the axial direction set horizontally. That is, the lid activation plate 18 is composed of a rotation plate that is provided so as to be rotatable with respect to the case body. Furthermore, the lid activation plate 18 constitutes a pull-up type activation structure 31 that links the activation of the expansion drive device 16 to the opening operation of the lid activation plate via a linkage means such as an axis activation structure 30, for example. It becomes a part of the operating device 17. The pivot shaft includes a shaft rod member 28 that is pivotally supported by a shaft support portion 27 that is integrally provided on the lower surface of the inside of the bag body 22 of the case body 12 so as to be rotatable about its axis. The lid activation plate 18 is fixed to the shaft rod member 28 via two arm portions 18a extending from the lower side of the flat lid plate main body to the case body side in a substantially L shape. Simultaneously with the rotation, the shaft rod member 28 rotates about the axis. As shown in FIG. 4, the arm portion 18 a of the lid activation plate 18 forms a part of the outer plate portion on the lower surface of the case body 12. As shown in FIGS. 2 and 6, the lid activation plate 18 rotates about 90 degrees around the pivot shaft with respect to the case body 12 and is retracted so as not to obstruct the floating bag that expands and expands. As will be described later, the shaft rod member 28 extends through the partition 20 and into the cylinder accommodating portion 24, and constitutes a part of the shaft rotation starting structure 30. Furthermore, in the present reference example , a packing or the like (not shown) is provided at the edge between the lid activation plate 18 and the opening of the case body 12 to provide a watertight sealing structure in which water does not enter inside when the lid is closed. Although the watertight structure of the case body 12 is not necessarily required, the watertight structure can protect the floating bag and the cylinder inside the case body from water.

As shown in FIGS. 1 and 4, in this reference example , the case body 12 can be attached to the case body 12 in close contact with a required position of the human arm, for example, the outer peripheral position of the upper arm near the shoulder. The fastening belt 32 is provided as an attachment member. The fastening belt 32 has, for example, a double upper and lower configuration and fastens two portions of the arm portion. In addition, the structure which fastens one place of an arm part with a belt may be sufficient. Each fastening belt 32 is made of, for example, a flexible belt member, and is integrally fixed to the left and right sides of the case body 12 on the left and right sides thereof. It is attached via the part 36. The fastening belt 32 has one end side 321 detachably connected to the first connecting collar 34, and the free end side 322 on the other end side is detachably linked to the second connecting collar 36, An endless state is formed by the fastening belt and the case body, and attached to the outer peripheral position of the upper arm portion in a tightly wound state. For example, the fastening belt 32 is provided with a connecting portion 38 made of a hook-and-loop fastener or the like at a folded portion where the free end side 322 is wound around the second connecting collar portion 36, and the thickness of the wearer's arm is provided. It is fastened in close contact correspondingly. Note that the fastening belt 32 may have a configuration in which an intermediate position in the longitudinal direction is fixed to the case body, and connecting portions such as hook-and-loop fasteners and hooks are formed on both ends thereof. The fastening belt 32 may be formed of any material such as cloth, leather, chemical fiber, vinyl resin, for example, but is preferably water-resistant and formed of a material that expands and contracts like rubber. May be. Moreover, it is good also as a structure which fastens a connection part with a buckle etc. FIG. Further, the attachment member is not limited to the configuration of the fastening belt that is directly attached to the human arm, but may be any other configuration such as a configuration that is attached to clothing.

As shown in FIG. 1 and FIG. 2, the bag 14 is normally accommodated in the case body 12 so as to fit in the palm of the hand or slightly larger than that and accommodated in the case body 12, and expands outside the case body in an emergency and has a large buoyancy Is a buoyancy means that can support a part of the body of the wearer M on the water. That is, the buoyant bag 14 is normally housed in the light and small case body 12 in a contracted state with a very small size, and supports a part of the human body when inflated. In the present reference example , the float 14 is made of a shrinkable and inflatable bag member made of a material such as thin polyethylene, vinyl chloride resin, or rubber. The air bag 14 is accommodated in the air bag accommodating part 22 of the case body 12 in a contracted state, and is fixed to the inner wall of the case so as to be inflatable. The float 14 is connected to the expansion driving device 16 via a supply pipe 40. During expansion driving, gas flows from the expansion driving device 16 to the inside via the supply pipe 40 and is sealed to form a substantially three-dimensional solid body. It expands into a shape (two-dot chain line in FIG. 2), and a relatively large buoyancy on the water acts on the vicinity of the body part to which the case body 12 is attached. Capacity upon expansion of the bladder 14, for example, the wearer's size, is set in the buoyancy supportable size part of the body said mounting person in response to weight, etc. In the present reference example, for example, at least It is set to about 3000 to 5000 ml. The buoyancy of the buoyancy bag is designed according to the application situation at the time of drought, and is set larger when it is necessary to apply a large buoyancy for a long time. For example, if the float 14 is formed in a conspicuous color such as white, yellow, or fluorescent color, it is easy for others to find it.

As shown in FIGS. 1, 3, and 7, the expansion drive device 16 is an expansion drive means that is accommodated in the case body 12 and drives the float 14 to expand in an emergency. In the present reference example , the expansion drive device 16 includes a cylinder 42 that compresses and encloses a gas such as compressed air or compressed carbon dioxide for expansion of the air bag 14. The cylinder 42 is normally closed by the closing plug portion for gas outflow. In an emergency, the cylinder 42 opens the closing plug portion by the operation of the operating device 17 and supplies the gas to the bladder. The cylinder 42 is accommodated in the cylinder accommodating portion 24 divided by the partition 20 of the case body 12, and is connected to the floating bag 14 via a supply pipe 40 that is disposed to penetrate the partition 20 laterally. A closing valve 44 as a closing plug is integrally attached to the cylinder 42 and connected to the supply pipe 40 through the closing valve 44. In an emergency, the cylinder 42 is opened by pushing the closing valve 44 toward the cylinder main body to be in an internal communication state with the supply pipe 40, and the compressed gas inside the cylinder is pumped into the floating bag 14 through the supply pipe 40. The air bag 14 is supplied and inflated. In the present reference example , the expansion start operation of the cylinder 42 in an emergency, that is, the opening operation of the closing valve, is performed in accordance with the rotation during the opening operation of the lid activation plate 18 from the outside, and the pull-up type activation structure 31 is performed. It is realized by.

As shown in FIGS. 1, 7, and 8, the operation device 17 is an activation operation unit that activates the cylinder 42 by operating from the outside of the case body 12. In the present reference example , the operating device 17 includes an activation / release mechanism 29 that simultaneously activates the cylinder 42 and opens the lid activation plate of the case body. Specifically, the activation opening mechanism 29 is an opening / closing portion of the case body 12, and the lid activation plate 18 that is opened by a pulling operation, and the cylinder 42 is activated for the opening and opening operation of the lid activation plate 18. And a pull-up type starting structure 31 including linkage means for linkage. The linking means includes an axis-starting structure 30 that starts the cylinder 42 in conjunction with the turning operation of the lid starting plate 18. The shaft-starting structure 30 is fixed to a closing valve 44 that is integrally attached to the above-described cylinder 42 and is opened by pushing toward the cylinder main body side, and an extension end of the shaft rod member 28 to the inside of the cylinder accommodating portion 24. Activation piece 46. The closing valve 44 is integrally formed with an overhang receiving portion 44a that is in contact with the starter piece 46 and expands so as to receive the pressing force. The starting piece 46 is formed of, for example, a cam-shaped plate member or piece member having a substantially rectangular corner with a rounded shape, and one end is fixed to the end of the shaft rod member 28. It rotates together and rotates integrally with the lid activation plate 18. When the lid activation plate 18 is closed, which is normal, the activation piece 46 is in a laid-down state as shown in FIG. 7, and is retracted from the closure valve 44, and the closure valve 44 is kept closed, that is, the cylinder is not activated. Yes. On the other hand, when the lid actuating plate 18 is opened and opened, the lid is rotated approximately 90 degrees together with the shaft rod member 28 as shown in FIG. The closing valve 44 is pushed toward the cylinder main body side to open the closing valve 44. Thereby, the structure which expands and activates the cylinder at the time of the lid opening operation of the lid activation plate 18 can be realized with a simple structure.

Furthermore, in this reference example , as shown in FIG. 5, the cylinder 42 is taken out and attached to the outer plate part on the back side of the case body 12 and on the cylinder housing space 24 side. 48 is provided. The open / close door 48 is watertightly sealed with, for example, a packing (not shown), and is detachably fixed via a screw 50 or the like. For example, even after being used once in an emergency, the water rescue apparatus can be reused by opening the door 48 and replacing the used cylinder 42 with a new cylinder. Note that the cylinder 42 is not limited to one in which only a gas such as compressed air is enclosed, and may be one in which a substance that closes a hole such as a rubber emulsion (latex) is enclosed together with the compressed gas. In this case, for example, even when the floating bag 14 is partially damaged and a small hole is opened after being used in the case of water shortage, the rubber closes the hole when the floating bag expands due to gas, and gas leaks from the floating bag. Can be prevented, and the buoyancy on the water can be effectively applied. Therefore, since the check of the float bag may be roughened to some extent, the maintenance is easy and the certainty of the buoyancy operation in an emergency is further improved. Note that the bladder is exchanged according to the degree of damage to the bladder. Moreover, it is not restricted to the aspect which can replace | exchange the cylinder 42 and can use a water rescue apparatus repeatedly, You may comprise in the aspect which can be thrown away after using once at the time of a water shortage. At this time, for example, it is not necessary to provide the opening / closing door 48, and the water rescue device 10 can be manufactured at a relatively low cost by simplifying the configuration.

In this reference example , the lid activation plate 18 may be configured to rotate around the vertical axis along the longitudinal direction of the cylinder 42, for example, and may be integrated with the case body and the thin portion without providing the shaft rod member. Any other configuration such as a configuration of being connected to and rotating may be used. Further, the lid activation plate 18 is not limited to a configuration that rotates with respect to the case body 12, for example, a configuration that slides on and off the case body 12, or a detachable attachment that opens and closes and separates from the case body. Thus, the case body may be opened. In any case, it is convenient to use any other activation / release mechanism that allows the closure valve 44 to be opened at the same time as the lid activation plate 18 is opened from the outside. In addition, for example, the opening of the lid activation plate 18 and the activation of the cylinder 42 may be linked through other linking means such as a rope, a protruding piece or a link mechanism, a gear mechanism, or the like. The cylinder shut-off valve 44 is, for example, one that opens and closes by turning a valve body that is provided intersecting the gas flow path around the valve shaft, or that opens and closes the valve body in the gas flow path for opening and closing. Any other configuration such as a configuration may be used. Further, the shut-off valve 44 is not limited to being integrally attached to the cylinder 42, and may be provided, for example, at an intermediate position of the supply pipe 40 or may be provided at the gas inlet of the float bag 14. Further, the connection between the float bag 14 and the cylinder 42 may be configured such that the closing plug portion of the cylinder 42 is directly connected to the float bag 14 without using the supply pipe 40. In this case, the gas outlet of the cylinder directly faces the inner space of the bag, and an improvement in the inflation speed of the bag can be expected. Further, as described later, the cylinder 42 may be installed inside the float 14. Further, the closing plug structure for closing the gas outlet of the cylinder 42 is not limited to the above-described closing valve structure, and the gas outlet is opened by rupturing a part of the cylinder container through an opening groove at the time of activation. Any other structure such as an easy opening lid may be used. The operating device 17 is configured according to the closing plug structure. The case body 12 is provided with a water-tight material such as plastic so as to have a watertight structure. For example, the case body 12 does not have to be a strict watertight structure, and the case body is formed with a water-permeable structure. Also good.

Next, the operation of the water rescue apparatus 10 according to this reference example will be described with reference to FIG. For example, the water rescue device 10 according to the present reference example is attached to the upper arm portion close to the wearer's shoulder through the fastening belt 32 before swimming in the sea or when entering the ship. The device can be easily attached by the fastening belt, and the case body 12 is light and small, so that it does not get in the way of swimming and work, and there is little uncomfortable feeling at the time of attachment. As shown in FIG. 9, for example, when a drought accident such as drowning occurs, the lid activation plate 18 is opened and opened by a hand on the arm side not wearing the device. By opening the lid actuating plate 18, as shown in FIG. 2, an expansion expansion path to the outside of the bag 14 accommodated in the case body 12 is opened by opening the bag bag housing portion 22 side of the case body 12. At the same time, as shown in FIG. 8, the opening piece 46 pivots upward in accordance with the opening operation around the pivot shaft of the lid starting plate 18, and hits the closing valve 44 attached to the cylinder 42. Then, the closing valve 44 is pushed toward the cylinder main body to open the closing valve. When the closing valve 44 is opened, the compressed gas inside the cylinder is pressure-fed and supplied into the air bag 14 through the supply pipe 40 to expand and expand the air bag 14. As a result, as shown in FIG. 9, the body can be prevented from sinking by applying a relatively large buoyancy to the vicinity of the upper arm of the wearer M from the inflated float 14 to protect the life of the wearer M. it can. As described above, since it can be started simply by a manual operation such as opening and opening operation of the lid starting plate 18 constituting a part of the case body 12, the case body mounting position can be obtained even in an emergency state such as drowning. By simply grasping roughly, you can quickly and easily operate the lid activation plate by hand. At the same time, by opening the lid activation plate 18, the activation of the inflation of the bladder 14 and the securing of the expansion expansion path from the closed bladder storage space of the case body 12 to the outside are performed at the same time.

To do. The activation piece 60 is formed to extend from the lower end side of the lid activation plate 18 in a substantially L-shaped direction and further extend from an arm portion 18 a connected to the shaft rod member 62. A round-shaped protrusion protruding toward the inside of the case body is formed on the tip end side of the activation piece 60, and the opening piece 56 is pressed from the outside of the bag without breaking the bag. The starting piece 60 forms a part of the outer plate portion on the lower surface side of the case body 12. As shown in FIG. 13, the activation piece 60 is located at a standby position where the cylinder 42 a is not activated at the normal time, that is, when the lid activation plate 18 is closed. As shown in FIG. 15, in an emergency, the activation piece 60 rotates together with the lid activation plate 18 in accordance with the opening operation of the lid activation plate 18 and advances toward the closed end wall 54 of the cylinder. Then, the open piece portion 56 of the bomb 42a is pushed inward from the outside of the buoyancy bag 14 toward the inner side of the bomb 42a, and is broken and opened from the opening groove 54 to supply the compressed gas inside the bomb into the buoyancy bag 14. Start to expand. It should be noted that the portion of the float 14 to which the starting piece 60 hits may be formed slightly thick so that it is difficult to break, or a synthetic resin film, rubber, or other fabric may be stretched in a cloth shape, or any other structure It is good to prevent breakage of the floating bag.

In the present embodiment, as in the reference example , the portability is good, and there are effects such as being able to inflate and activate the floating bag easily and quickly when a drought occurs. In particular, in the present embodiment, since the cylinder 42a for inflating driving of the bag 14 is sealed and installed inside the bag 14, the case body 12 has a configuration in which the cylinder and the bag 14 are separated into separate housing parts. The body 12 can be made smaller, and portability is improved. Furthermore, when the cylinder 42a is opened, the gas outlet of the cylinder directly faces the floating bag inner space, and as a result of increasing the inflation speed of the floating bag 14, the effectiveness and reliability of the lifesaving device are further improved. Furthermore, the structure of the easy opening lid 58 can realize the cylinder closing plug portion with a simple configuration, and does not require a separate member such as a supply pipe for connecting the air bag 14 and the cylinder 42a, and has a simple structure with a small number of parts.
