BACKGROUND OF THE INVENTION
The present invention relates to a life preserver that is convenient for use by persons engaged in water work, water athletes such as boating, and persons enjoying water leisure.
[0002]
[Prior art]
In general, a waistcoat type life jacket is known as a life preserver worn by a water worker or the like. That is, there are a type in which an inflatable body that is inflated with high-pressure gas is accommodated in the waist of a waistcoat type vest without both sleeves, and a fixed type in which a buoyant body such as styrofoam or cork is sewn.
[0003]
Life jackets are worn at all times when there is a possibility of falling water, but when worn, they become bulky and difficult to move, and they become very hot when the temperature is high, so fishing crews who are forced to work hard Did not like wearing. For this reason, even if it was legally required to wear it, there were cases where it was actually working without a life jacket. In addition, water leisure such as fishing and yachting is also popular, but for the same reason, it was not possible to wear life jackets and get out on the water, causing a flood accident. Furthermore, it is thought that wearing life jackets is preferable during practice in boating and the like, but it has not become widespread because it interferes with the movement.
[0004]
Therefore, the waist belt is passed through a horizontally long rectangular floating bag with an air valve, a removable lever-type fastener is provided at the end of the belt, the floating bag is folded and flattened, and the entire waist is configured as a single belt. A wearable portable floating bag has been proposed (see, for example, Patent Document 1). In addition, a belt-type floating bag that is longer than the waist circumference length so that it can be attached to the waist of the wearer, the margin part is folded inward, and a gas supply device is provided outside thereof has been proposed (see, for example, Patent Document 2). ).

The perspective view (A) of the state which folded the float bag in the range of the cover, the perspective view (B) which opened the cover, and the state which expanded the one side of the float bag which was folded, and sectional drawing which shows how to fold the float bag ( C). The lifesaving device of the present embodiment mainly includes a cover 1, a float bag 2, and a cutting device 3 attached to the float bag 2.
[0011]
The cover 1 is made of a flat material that can be worn around the waist of the human body, that is, the wearer 4, such as ballistic nylon, has a horizontally long shape, and is a thin belt that is also made of ballistic nylon or the like at both ends in the horizontally long direction. 5 and 5 are fixed by sewing or the like, and a buckle male 6 and a buckle female 7 are attached to the tip thereof.
[0012]
The cover 1 has a width that extends at least around the back of the wearer 4 and can be formed into a flat cylindrical shape in which the upper edge 1a and the lower edge 1b are folded to open both sides. Further, the central portion on the lower edge 1b side of the cover is cut out so that water can enter the inside in the folded state as described above, and the mesh material 8 is sewn to form an opening.
[0013]
A velcro fastener 9 is provided on each of the upper edge 1a and the lower edge 1b of the cover 1 so that it can be locked when folded. The width dimension of the cover 1 is set to an appropriate dimension that can fit the waist of the wearer 4 when worn. Of course, various sizes may be prepared according to the physique of the wearer 4.
[0014]
The float bag 2 is made of, for example, a nylon base cloth coated with polyurethane and waterproofed. The float bag 2 has a flat, substantially rectangular parallelepiped shape when not inflated, and has a rod shape when filled with gas when inflated. In order to make such a floating bag 2 take a shape that can be referred to as a substantially U-shape or a horseshoe shape in which the center part of the body of the wearer 4 is discontinuous as shown in the figure when inflated, both end portions of the floating bag 2 Is fixed to the cover 1 by bonding or the like over an appropriate length. This fixing may be detachable using a Velcro fastener or the like.
[0015]
The material of the float bag 2 may be any material as long as it can be used as a floating body, but it needs to be folded into the cover 1. That is, the float 2 can be attached to the cover 1 by making it substantially flat as shown in FIG. 1A so that the vertical direction of FIG. 1B is along the vertical direction of the body of the wearer 4. Further, the cutting device 3 is fixed to the central portion, that is, the upper portion of the mesh material 8 forming the opening of the cover 1, and the wearer 4 inflates the floating bag 2 with the mouth slightly from the center from one end side. The oral tube 10 is fixed.
[0016]
Further, a thin belt 11, 11 made of ballistic nylon or the like is also fixed to the opening end of the float bag 2 by sewing, and a buckle male 12 and a buckle female 13 are attached to the tip thereof.
[0017]
In addition, the length dimension of the float bag 2 shall be able to take the appropriate internal-diameter dimension which can be loosely fitted to the wearer's 4 waist, armpit, etc. at the time of inflation. Of course, the floating bag 2 may be prepared in various sizes according to the physique of the wearer 4.
[0018]
The cutting device 3 is a gas filling device for injecting water from the mesh material 8 or the like or manually sending carbon dioxide for expansion into the float 2. A known device may be used as the cutting device 3. For example, the one shown in FIG. 3 includes a spool 22 as a sensor, an operating spring 23, an automatic lever 24, an insert needle 25, a manual lever 26, etc. in the casing 21. A string 27 for operating the manual lever 26 and a winding cap 28 are provided outside, and a carbon dioxide gas cylinder 30 can be attached to and detached from the insert needle 25 via a packing 29.
[0019]
That is, when the spool 22 detects the intrusion of a liquid such as water, the operating spring 23 drives the automatic lever 14 to rotate through the transmission shaft 31, and a hole is made in the sealing port 32 of the carbon dioxide gas cylinder 30 by the insert needle 25. Gas is fed into the float 2. Further, when the wearer 4 or the like pulls the string 27, the same operation as described above is performed. Of course, the gas filling device is not limited to the illustrated example, and various devices can be employed.
[0020]
In this embodiment, as shown in FIG. 2 (C), the floating bag 2 is folded so as to cover the cutting device 3 from above, and the cover 1 is further wrapped outside, and the mesh material 8 that is the opening of the cover 1 is the most. It can be positioned below. With this folding method, unless the wearer 4 falls down, the cutting device 3 does not malfunction even if a wave is applied, and the risk associated with malfunction can be reduced.
[0021]
The oral tube 10 may be positioned on the front side of the body of the wearer 4 when the float bag 2 is inflated. In other words, when the inflation degree of the float bag 2 is low, breather is blown to further inflate it. Just do it. Since various types of oral tubes 10 can be used, detailed illustration and description are omitted.
[0022]
Next, with reference to FIG. 2 and FIG. 4 thru | or FIG. 7, the usage method of the life preserver of this embodiment is demonstrated.
First, as described above, both ends of the float bag 2 attached to the cover 1 are folded as shown in FIGS. 2B and 4, the upper edge side is folded down as shown in FIG. When the edge 1a side is folded down and the Velcro fasteners 9 of the cover 1 are brought together, the storage of the floating bag 2 in the cover 1 is completed. In this state, as shown in FIG. 5, it is attached to the waist of the wearer 4 like a normal belt.
[0023]
When the wearer 4 falls from, for example, the boat, water enters the cover 1 from the mesh material 8 that forms the opening of the cover 1 or the joint of the cover 1, and the spool 22 of the cutting device 3 enters the water. As described above, the automatic lever 24 rotates, and a hole is made in the sealing port 32 of the carbon dioxide gas cylinder 30 with the insert needle 25, and carbon dioxide gas is fed into the floating bag 2. The state is shown in FIG. At this time, if the amount of carbon dioxide gas entering the float bag 2 is too large, the float bag 2 swells to a bar shape or a state close thereto, and the wearer 4 cannot support the body with the float bag 2. Therefore, as shown in FIG. 6, the amount of carbon dioxide gas fed from the gas cylinder 30 into the float bag 2 is appropriately reduced so that both ends can protrude forward of the body of the wearer 4 along the bend of the cover 1. .
[0024]
However, in the state of FIG. 6, the front side of the float bag 2 remains open, so that the wearer 4 fits the buckle male 12 and the buckle female 13 attached to the belts 11, 11 of the float bag 2, and then comes out of the body. Do not. If necessary, lift the bag 2 so that it fits under the armpit. Further, if necessary, the degree of expansion of the float bag 2 is adjusted by blowing the breath into the float bag 2 through the oral tube 10 or allowing the carbon dioxide gas to escape.
