Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

FIELD OF THE INVENTION The present invention relates to lifeboats and, more particularly, to personal lifeboats.

[0002]

2. Description of the Related Art Conventionally, a lifeboat to be mounted on a conventional flying body is generally provided with a floor plate in a circular air chamber, on which the victim is to board.
Although this type of lifeboat has the advantage that a plurality of victims can board, it is large and needs to be separately mounted in the fuselage, and may not be able to respond in an emergency.

In order to cope with such a situation, personal lifeboats have been developed. In such a lifeboat, a hood F is extended in a boat-shaped air chamber C to protect the victim from the weather. The hood F has a structure in which a window W is provided on a portion corresponding to the face of the victim, so that the window W can be seen outside, and a slide fastener S is provided from the bow to the window W. It is common.

In a lifeboat of this type, a victim gets in with the apex of an isosceles triangle on the lower body side and the lower side on the upper body side, expands the hood F fixed to the upper end of the air chamber C, and slides it. The hood F is closed by sliding S. In this case, if a lifeboat is overturned due to some situation, it is necessary to slide the slide fastener S to the bow side, open the hood F, and escape.

[0005] However, unless the slide fastener S is slid to a certain distance, it is impossible to obtain a sufficient spread for escape. Further, in an emergency and in a cold region, there is a drawback that it is difficult to slide the slide fastener S due to reasons such as a bite of a hand.

The present invention has been made in view of the above-mentioned problems, and provides a life-saving boat having a hood which can escape quickly and easily when the life-saving boat is overturned. The purpose is to:

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a life-saving boat according to the present invention includes a life-saving boat having an air chamber formed in a boat shape and a hood covering a portion surrounded by the air chamber. In the boat, the hood includes a lower body hood, which covers at least a remaining portion of the stern portion, and the lower body hood, wherein the hood covers the bow-shaped portion of the air chamber formed in a boat shape from the stern portion to the stern portion. Is characterized in that the upper body hood can be opened and closed by a hook-and-loop fastener with a slide fastener.

According to the present invention, since the upper body hood covering the upper body can be opened and closed by the hook-and-loop fastener,
By opening the hook-and-loop fastener, it is possible to obtain a sufficient clearance for escape, and there is an advantage that the escape can be performed quickly and easily.

FIG. 1 is a perspective view of a lifeboat B according to the present invention.
FIG. 2 is a side view. As is clear from these figures, the lifeboat B according to the present invention has a manual expansion chamber 1 that expands with compressed gas and a lower air chamber 2 that communicates with the manual expansion chamber 1. have. The lower air chamber 2 is formed up to a substantially intermediate portion of the manual inflatable air chamber 1 while the cross section of the air chamber is gradually reduced from that of the stern of the lifeboat. In the above lifeboat, sit down at the rear of the lifeboat and extend your legs in the bow direction.
This is because the stern imposes more weight on the stern.

A flexible floor cloth 3 is spread on the bottoms of the manual inflatable chamber 1 and the lower chamber 2, and a front portion covers a joint portion in front of the manual inflatable chamber 1 to form a boat. The bottom is formed so that it becomes. The floor cloth 3 wraps around the entire body when a victim is boarded, and as a result, lowers the position of the center of gravity of the lifesaving boat B and stabilizes it. Since the floor cloth 3 is made of a cloth that is flexible and does not transmit water, it can be easily folded.

The manual expansion air chamber 1 and the lower air chamber 2 communicating therewith are provided with a compressed gas, for example, a carbon dioxide gas cylinder 11.
It expands with more carbon dioxide gas. When carbon dioxide gas does not erupt due to some failure,
The air can be expanded by blowing air from an air suction pipe 12 attached to the manual expansion air chamber 1.

In the upper part of the manual inflation chamber 1, there is formed an expiration chamber 4 which expands by blowing air. Manual expansion chamber 1 and lower chamber 2 as described above
If the buoyancy is insufficient, the buoyancy can be increased by blowing air from the air suction pipe 41 provided in the expiration / expansion chamber 4 when the person gets into the lifeboat B.

A hood 5 is provided above the expiration / expansion chamber 4. The hood 5 includes an upper body hood 51 that covers the upper body from the victim's head and a lower body hood 52 that covers the lower body. The hood 5 is folded and fixed on the exhalation / expansion chamber 4. Therefore, when the victim gets into the lifeboat, the hood can be extended to cover the whole body.

FIG. 3 is a plan view of the lifeboat B. As is clear from FIG.
Is folded and fixed on the upper surface of the stern portion B1 of the expiration and expansion air chamber 4 formed in a boat shape, while the lower body hood 52 is fixed to the upper surface of the manual air chamber 4 from the bow portion B2 to the stern portion B1. Have been. In this embodiment, the stern-side fixing portion B11 of the lower-body hood 52 is located closer to the stern portion B1 of the lifeboat B than the fixing position B12 of the upper-body hood 51 on the bow portion side. Sometimes, the upper body hood 51 becomes the lower body hood 5
2 (see FIG. 4).

A slide fastener 521 is provided at the other end of the lower body hood 52, which is not fixed, and can be opened and closed freely. This slide fastener 52
The one handle 522 is provided on both the upper surface and the lower surface of the lower body hood 52, and is also useful from outside (when the victim cannot open the slide fastener 521, the rescuer can open the slide fastener). The slide fastener 521 can be opened from the inside (easy to open for the victim) (see FIG. 5).

On the other hand, the upper body hood 51 includes a stern portion B1.
It is attached to the upper surface of the expiration / expansion chamber 4 in the direction of the bow portion B2 so as to cover the upper body of the victim. As described above, the lower body hood 52 covers the end in the stern portion B1 direction. As shown in FIG. 6, a hook-and-loop fastener 511 is attached to the other end of the upper body hood 51 which is not fixed to the upper surface of the expiration and expansion chamber 4.
The upper body hood 51 can be closed by attaching the hook-and-loop fasteners 511 to each other.

The upper body hood 51 is provided with a window 512 through which the outside fastener can be seen.
1 is a bow portion B2 end 51 of the upper body hood 51
3 to the window 512, and from the window 512 to the fixed portion 514 on the stern portion B1 side, so that the upper body hood 51 is completely opened (see FIG. 4). In addition, a mesh 515 is provided inside the portion where the head of the victim contacts, so that, for example, when the victim is wearing a helmet, the hermet and the inside of the upper body hood 51 do not adhere. (See the broken line in FIG. 1).

Such a life-saving boat B is folded and stored in a storage bag 6 as shown in FIG. The storage bag 6 has a belt 7, and usually, the lifesaving boat B is folded and stored in the storage bag 6, and is attached to the waist portion. And storage bag 6
The lifeboat B is connected to the lifeboat B by a cable 61 so that the victim and the lifeboat B are not separated from each other. Further, an accessory storage bag 71 is provided on the belt 7 so as to store simple emergency supplies. Further, the lifeboat B can be provided with a sea anchor 8 in order to improve stability.

The manual expansion chamber 1 and the lower chamber 2 are
As shown in FIG. 2, each has two bent portions 13 and 21 so as to form a boat when inflated. By bending at the bent portions 13 and 21, a triangular boat is formed. It is designed to expand.
FIG. 7 shows a sectional view of the bent portion. As is clear from this figure, the central part of the air chamber wall 9 (part of the air chamber)
Reference numerals 91 are fixed to each other. Therefore, a constricted portion 92 is formed when the air chamber expands, and a communication passage is formed in the upper portion 93 and the lower portion 94. By forming the bent portions 13 and 21 having the constricted portions 92, the manual inflated air chamber 1 and the lower air chamber 2 are easily bent at the bent portions 13 and 21.
By injecting the carbon dioxide gas from the carbon dioxide gas cylinder 11, the boat shape is easily formed. That is, even if the expansion force is insufficient for some reason, a stable boat shape can be formed, and the victim can easily get in.

When such a lifeboat is used, when it is thrown into the sea or the like, the open rope of the storage bag 6 is pulled (at the same time, the carbon dioxide gas cylinder transfers the carbon dioxide to the manual inflation chamber 1 of the lifeboat). In the lifeboat, the manual inflatable chamber 1 and the lower chamber 2 communicating therewith are inflated. The lifeboat may be separated from the victim by the momentum of the inflation, but the lifeboat is connected to the storage bag 6 by a cable 61, and the storage bag 6
Is attached to the victim's waist by the belt 7,
The lifeboat never leaves the victim.

When the carbon dioxide gas is injected into the manually expanded air chamber 1 and the lower air chamber 2 as described above, the bent portions 13 and 21 are bent.
It expands while bending, forming a boat-shaped lifeboat. The victim gets into the lifeboat with the upper body on the stern side and the lower body on the bow side. If the buoyancy is insufficient, air is supplied from the mouth to the air supply pipe 41 to inflate the air. The chamber 4 is inflated. Thereafter, the lower body hood 52 is closed by sliding the slide fastener 521 of the lower body hood 52 by gripping the inner or outer handle 522, and then closing the upper body hood 51.
By attaching the hook-and-loop fasteners 511 to each other, the victim's upper body and lower body are covered. At this time, since the upper body hood 51 covers the end of the lower body hood 52, wind and rain can be favorably prevented.

When the rescuer rescues a victim, the lower body hood 52 can be easily opened by the outer handle 522, while the upper body hood 51 is closed by the hook-and-loop fastener 511. , Which can also be easily opened from the outside. That is, even if the victim does not open the fastener, the rescuer can easily open the hood 5 from the outside.

On the other hand, when the lifeboat B is overturned,
By pulling the hook-and-loop fastener 511 from the window 512 portion or other portions of the upper body hood 51, there is an advantage that a gap to escape can be easily formed.

In the above embodiment, no bent portion is formed in the expiration / expansion air chamber, but it is apparent that a bent portion may be formed in this expiration / expansion air chamber. In addition, an exhalation-expansion air chamber may be formed below the lower air chamber.

[0025]

As described above, according to the lifeboat according to the present invention, the upper body hood covering the upper body can be opened and closed by the hook-and-loop fastener, so that opening the hook-and-loop fastener is sufficient for escape. There is an advantage that a gap can be obtained and escape can be performed quickly and easily.
