Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lifesaving device that is always kept on ships and the like and is used by filling the inside with gas and inflating it in the event of a marine accident.

[Conventional technology]

In general, this type of life preserver is made of a non-breathable cloth material such as nylon rubber-coated cloth, and is required to have a donut-shaped bag body, and the interior is divided into two air chambers for safety reasons. The structure of the two air chambers is formed by stacking three cloth materials of the same shape and bonding the inner peripheral edge and the outer peripheral edge, so that the two air chambers are stacked one above the other. A cut case (carbon dioxide gas filling device) is connected to each of these air chambers, and an auxiliary air supply rubber tube is attached to each of the air chambers, so that each air chamber can be filled with gas.

[Problem that the invention seeks to solve]

In the configuration of the conventional example, the reason for having two air chambers from the viewpoint of safety is that even if one air chamber is ruptured, the floating state can be maintained in the other air chamber, but in reality, two air chambers are used. A major cause of breakage is when the tip of a nail or other object gets caught on or penetrates a sharp object.
Even with the structure of two air chambers, if they are stacked one on top of the other, one sharp member can break through the two air chambers at once, which poses a major safety problem.

In addition, as mentioned above, conventional life preservers are made of three layers of cloth that are layered and glued together, so the glued parts are thicker overall, and when folded for storage, the rigidity of the glued parts allows it to be folded into a small and compact size. There is also the problem that it cannot be folded.

[Means for solving problems]

As a specific means for solving the above-mentioned problems, the present invention provides a pair of independent bags each having a hook-like planar shape by connecting a body part and a hook-like part, and each body part has a cut case. and an auxiliary air supply rubber tube is attached, and an auxiliary cloth material of the same shape is attached to one of the hook-shaped parts to form a triple structure, and the body parts are connected with the hook-shaped parts facing each other and overlapped, and the one of the hook-shaped parts The present invention provides a lifesaving device characterized in that the other hook-shaped part is inserted into the inside of the auxiliary fabric material of one part and each end is locked, the pair of bags are formed separately, Since the bodies of the bags are connected adjacently, even if one bag is pierced and torn, the other bag will not be affected in any way, and the role of the hooked part in supporting the head will not change. First, it has excellent safety, and since the adhesive part is double-layered, it is thin, and can be formed flexibly, so it can be folded compactly.

〔Example〕

Next, the present invention will be explained in more detail with reference to the illustrated embodiment. The life saving device of the present invention is composed of two separate bags 1 and 2 having the same shape. This bag body is formed by cutting a non-breathable cloth material into approximately the same shape, so that the body portions 3 and 4 and the hook-shaped portions 5 and 6 are connected to each other so that the planar shape thereof is approximately hook-shaped. . Both bags are made by overlapping two cloth materials and bonding the peripheral edges to form a bag each having an independent air chamber. Cut case 7,
8 and auxiliary air supply rubber tubes 9 and 10 are attached, and the cut case is filled with compressed liquid carbon dioxide, and by opening the valves of the cut cases 7 and 8 by pulling strings 7a and 8a, respectively, liquid carbon dioxide is released. It is configured so that the gas evaporates and inflates each bag body 1, 2. The components of this type of gas filling device are substantially the same as those commonly used.

The hook-shaped part 5 of one of the bags 1 and 2 is provided with an auxiliary cloth material 11 having the same shape as the hook-shaped part on the back side thereof to form a triple structure. In this case, the auxiliary cloth material 11 is attached along the periphery of the hook-shaped part 5 by adhesive bonding in the same manner as in the formation of the bag body 1, and both ends 1 of the auxiliary cloth material 11 are attached.
1a and 11b are left open. A locking member 1 such as a snap is located near both openings.
2a, and the other locking member 12b is provided on the hook-shaped portion 6 of the other bag body 2 in correspondence with these locking members.

As shown in FIG. 5, both bags 1 and 2 configured in this manner are positioned so that the hooked portions 5 and 6 face each other and overlap each other, and the abutting portions of the body portions 3 and 4 are aligned. Connect by adhesive or other means. As shown in FIG. 6, the hook-shaped parts 5 and 6 are inserted inward from one open end 11a of the auxiliary cloth material 11 provided on one of the hook-shaped parts 5, and the other end 11
When it reaches point b, the hook-shaped portions 5 and 6 are in an overlapping state, and the hook-shaped portions 5 and 6 are brought together by the auxiliary cloth material 11. In this way, both hook-shaped parts 5 and 6
In the stacked state, the locking members 12a and 12b provided at each end are engaged to connect them so as not to separate.

After both bags 1 and 2 are connected as described above, attachment belts 13 and 14 are attached to the back side. Various structures can be used for this mounting belt, but as shown in the figure, the mounting belt 13 that is fastened to the main parts is attached to the body parts 3 and 4 of the bags 1 and 2, and is fastened from the shoulders to the waist. A mounting belt 14 is attached extending from the vicinity of the base of the hook-shaped portions 5 and 6 to the mounting belt 13. The attachment of such a mounting belt can be changed as desired, as long as the bag can be stably attached to the upper half of the human body when the life preserver is attached. In the figure, the hook-shaped part 5,
The inner circular hole 15 formed by 6 is large enough to comfortably fit a human head.

[Effect]

As shown in FIG. 9, the life preserver of the present invention having the above-mentioned configuration is such that the head is inserted into the circular hole 15 formed by the hook-shaped parts 5 and 6, and the hook-shaped parts 5 and 6 are positioned at the neck and shoulders. The body 3 of the bags 1 and 2,
4 are placed on both sides of the chest with attachment belts 13 and 14. After the attachment, the strings 7a and 8a of the cut cases 7 and 8 are attached.
By pulling strongly, liquid carbon dioxide gas rapidly vaporizes and fills both bags 1 and 2, so that they have a predetermined swell. If the amount of carbon dioxide gas is small and the planned expansion cannot be achieved, the auxiliary air supply rubber tube 9,
Air is blown into each of the bags 1 and 2 from 10 to inflate them. The life preserver, which has been inflated to a predetermined value, is placed on the chest, neck, and back of the head, and allows the body to float in an ideal state. In particular, the hook-shaped parts 5 and 6 are located at the back of the head and form a pillow-like shape, making it easy to breathe and keeping the patient in a posture that does not cause fatigue.

〔Effect of the invention〕

As explained above, the life preserver according to the present invention is formed by a pair of independent hook-shaped bags in a plan view consisting of a body part and a hook-shaped part, so that the two air chambers are completely divided into left and right sides. They are independent, with only the hook-shaped parts being doubled, so even if the body of one of the bags were torn through, there would be no problem with the other bag. However, even just one hook-shaped part has the excellent effect of supporting the back of the head and making it possible to float in a stable state.

In addition, since the pair of bags have approximately the same shape, it is possible to mass-produce items with the same shape by cutting and gluing the cloth materials, and when connecting these bags, the mounting positions of other members can be set arbitrarily. This not only improves the overall manufacturing workability and can be provided at low cost, but also has an excellent economical effect, as if one bag is torn, only that torn bag needs to be replaced. play.

Furthermore, by connecting the torso and the hook-shaped part, a circular shape is formed through which the head can be inserted when it is attached, and when connecting the hook-shaped parts, an auxiliary fabric material is provided on one of the hook-shaped parts. Since the other hook-shaped part is inserted into the inside of the auxiliary fabric material and locked, the hook-shaped part becomes a pillow-like shape that supports the back of the head, and the body is placed in a supine position. It also has the excellent effect of allowing stable floating.

Furthermore, since most of the adhesive parts of the bag are double-layered, they are thin and flexible, so there is no rigidity when folding, and the bag can be folded compactly for storage.
