Description

The present invention relates to clothes and life jackets (life jackets, etc.) in case of drought.

Various life jackets have been devised, such as those using buoyancy materials, filling a bag-like airtight chamber with gas, and injecting exhaled air into a bag-like airtight chamber. If it is recognized that there is a high risk, it is worn in advance, and if an unexpected accident is encountered, it is not used for lifesaving. As a countermeasure, for example, Patent Document 1 proposes a method of using a special buoyancy material as the core of ordinary clothing, but it is not suitable for wearing throughout the seasons.
Further, Patent Document 2 devises a method of attaching a buoyant material that can be attached and detached to a normal jacket in advance or filling a bag-like airtight chamber provided inside the jacket in advance. In the event of an accident, it cannot be fully effective.

Many lives are lost every year due to drowning accidents, but many of them suffer from unexpected accidents, and therefore they often do not wear life jackets. In the present invention, a normally wearable upper garment has a function of a hermetic chamber capable of holding air, so that in the event of an accidental drowning accident, necessary buoyancy is generated, preventing panic of those who have encountered the accident. The purpose is to increase the survival rate.

The material on the front side and the back side of the upper garment are made of materials that are both airtight and strong, and they are stitched or joined to form an airtight chamber that can hold air. The required buoyancy can be generated by the air existing from the air or when the wearer injects exhaled air.

It is possible to prevent the loss of precious human lives in an unexpected water accident by providing a normal garment having a function as a life-saving device instead of a dedicated life-saving device.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.
FIG. 1 is a front view of an upper garment 1 according to the present invention, FIG. 2 is a rear view of the upper garment, FIG. 3 is a cross-sectional view taken along the dashed line AA in FIG. FIG. 5 and FIG. 6 are sectional views of an air inlet with a check valve according to the present invention.

1-4, nine airtight chambers (hereinafter referred to as air chambers) for holding air according to the present invention are configured. The air chamber 2a is configured by stitching or joining the front material 7a and the back material 8a (same type of material; the same applies hereinafter) to the wearer's right chest, and part of the air chamber 2a faces downward. It has an opening 9a. The air chamber 3a is configured by stitching or joining the front material 7b and the back material 8b to the right back portion of the wearer, and a part thereof has an opening 10a in the downward direction. The air chamber 4a is configured by stitching or joining the front material and the back material to the right shoulder, and passages 11a and 12a are provided so that the air can pass back and forth between the air chamber 2a and the air chamber 3a. ing.
The air chamber 5a is configured by stitching or joining the front material 14 and the back material 15 to the right collar, and a passage 13a is provided so that the air can be exchanged with the air chamber 2a. The air chambers 2b, 3b, 4b, and 5b are air chambers provided symmetrically with respect to the air chambers 2a, 3a, 4a, and 5a, and are disposed on the left part of the wearer.
In these air chambers 2 to 5, the material on the front side is made slightly larger than the material on the back side, and an air layer is easily formed even in a normal wearing state.
The air chamber 6 is configured by stitching or joining the front material 16 and the back material 17 to the hood portion, and forms an independent air chamber.

Each of the air chambers 2a and 2b, which are chest air chambers, has, for example, decorative pocket lids 18a and 18b stitched or joined to each other. 19b is attached, respectively keeping airtight.
In the air chamber 6 of the hood portion, a button-like air inlet 21 with a reverse valve is attached to a front band portion 20 connected to the hood while keeping airtightness.
With the above structure, three air chambers are formed. FIG. 4 schematically shows the air chamber system. The air chambers of a plurality of systems, for example, have higher safety because the air chambers of other systems function even when one place is broken.

Next, the effect when a drowning accident is encountered while wearing the upper garment according to the present invention will be described. It should be noted that the buttons and fasteners on the front of the upper garment are properly tightened.
First, in the air chambers 2 to 5 other than the hood 6, a certain amount of air is held between the front material and the back material in a normal wearing state. Moreover, the air is trapped in the air chamber and swells unnecessarily, and does not impair comfort. This is made possible by the fact that the material on the front side is made slightly larger than the material on the back side and that the air chambers 2a, 2b, 3a and 3b are always open in the downward direction. Is in a possible point.
Immediately after submergence, these initially retained air is gathered upward by water pressure to generate a minimum buoyancy. The L-shaped joint portions 22a, 22b, 23a, and 23b shown in FIGS. 1 and 2 are partitions for allowing a part of the initial retained air to remain in the air chamber even when the submerged portion is submerged in an inverted state, for example. is there.

In order to generate greater buoyancy, exhalation is injected through button-like air inlets 19a and 19b with check valves attached to the lids 18a and 18b of the chest pocket. Since the air inlet is button-shaped, it can be attached to a conspicuous part in terms of design, and the wearer can easily recognize the location of the air inlet even in an emergency.
Further, the hood 6 detachably attached to the rear collar portion forms an independent air chamber, and exhales through a button-like air inlet 21 with a check valve attached to the front band-like portion 20. By pouring, it becomes a large capacity floating bag. The hood 6 is not in a position to give buoyancy directly to the wearer in the state of wearing the upper garment, but it can be removed and held, and from the searcher by giving the lining a vivid color It has the effect of being easily discovered, and can give a sense of security to the victims.

FIG. 5 shows an example of the structure of a button-like air inlet with a check valve.
In this example, the end 27 of the button body is fixed between the metal button body 25 and the front material 24 by pressing and deforming the spacer 27 and the sealing material 29. The valve body 30 is made of a material having high elasticity and airtightness, and is directly joined to the front material 24. The exhaled air blown from the hole 26 enters the air chamber through the hole 31 provided in the valve body 30, but the air in the air chamber is removed when the valve body 30 comes into close contact with the end portion 27 of the button body. Does not leak. It is also possible to incorporate the valve body in the button body. FIG. 6 is an example of this.

Although it is desirable that clothes worn on a daily basis can be washed at home, the air chambers 2 to 5 of the upper garment according to the present invention are connected to the portions 9a, 9b, 10a, and 10b that are always open. Even if water enters, it is relatively easy to discharge the water and it can be washed at home.
The hood can be removed and washed daily to prevent water from entering the air chamber.
Due to these characteristics, it can be widely used as an upper garment for children.

Examples other than those described in the above-mentioned “Best Mode for Carrying Out the Invention” include waistcoats with no sleeves, and as a simple example, only the hood has the structure of the present invention. What can help in the case of one is conceivable.
