Description

Description: TECHNICAL FIELD The present invention relates to a dive dry suit.

<Conventional Technology and its Problems> Conventionally, wet suits have been generally used as diving clothes, but in recent years, dry suits in which seawater or the like is prevented from entering are becoming widespread. This dry suit has an advantage that it is particularly excellent in heat retention because water does not enter between the suit and the body.

On the other hand, in a dry suit, since it is necessary to prevent water from entering the inside, the inside diameter of the suit has conventionally been narrowed down so that the neck or wrist of the suit is in close contact with the body.
For this reason, when a user wears a dry suit or the like, it is very cramped and troublesome to pass through the neck and hands (especially the neck).

Therefore, the present invention solves the above-mentioned drawbacks of the conventional dry suit, and makes it easy to put on and take off the neck and wrist, and even in a dressed state, the neck and the like are released from the pressure state etc. except during diving. The purpose is to provide a dry suit that can be used.

<Means for Solving the Problems> In order to achieve the above object, the diving dry suit of the present invention has an annular airtight space S formed inside the suit neck 110 along the inner periphery of the suit neck 110 and independent from the others. A dedicated connection port for connecting the airtight space S of the expansion / contraction section 111 to freely enclose and discharge a swelling fluid at the outer side of the suit neck 110. The first feature is that the tool 112 is provided.

Further, in addition to the first feature, the dry suit of the present invention further includes an expanding / contracting portion 121 having an annular hermetic space S formed independently along the inner circumference of the suit wrist 120. At the same time, a dedicated connection fitting 122 is provided on the outer side of the suit wrist 120 to connect to the airtight space S of the expansion / contraction section 121 and freely enclose and discharge the fluid for expansion. Is the second feature.

<Operation> According to the first feature of the present invention, the expansion / contraction portion 111 is provided from the dedicated connection fitting 112 provided on the outer portion of the suit neck portion 110.
The fluid is introduced into the airtight space S of the
Expands, and adhesion to the human neck is secured. In a state in which the fluid in the airtight space S is drawn out via the connection fitting 112, the expansion / contraction portion 111 is retracted, a sufficient clearance is secured in the suit neck 110, and the human neck 210 is not pressed. Therefore, the user wears the suit 100 with the fluid removed from the expansion / contraction section 111,
By taking off, dry suit 100 very smoothly
Can be put on and taken off. Also, even when wearing a suit, the fluid is not sealed in the expansion / contraction section 111 until it enters the water, maintaining a comfortable state without feeling tight or squeezed be able to. And, of course, since the expansion / contraction portion 111 is expanded to ensure watertightness, it is possible to more reliably prevent water from entering as compared with the related art. Also, an appropriate contact pressure according to the thickness of the neck of the user can be adjusted.

Further, the expansion / contraction section 111 provided on the inner periphery of the suit neck 110
For the airtight space S, a dedicated connection port 112 is provided separately from the system by an air supply valve or the like that supplies air into the body of the dry suit 100, and a fluid is sealed from the dedicated connection port 112. , So that the suit neck 110
The expansion and contraction of the expansion / contraction section 111 can be performed independently of the air supply / exhaust operation and the state of the body of the dry suit 100, and therefore, anytime, anywhere, and in a short time. It can be done easily and quickly.

In addition, since the airtight space S of the expansion / contraction portion 111 provided on the inner periphery of the suit neck 110 is an airtight space independent of others, the airtight space S is not affected by the volume of other spaces and the like, and is independent. Air and the like can be quickly filled and discharged into the space S, and since the space is an airtight space, a reliable operation is guaranteed without leakage of the filled air and the like to the surroundings.

According to the second feature of the present invention, in addition to the function and effect of the first feature, the same effect as that of the first feature is obtained in the wrist portion 120 of the dry suit 100. This makes it very easy to insert and remove the human wrist 220, and can reliably prevent water from entering.

<Example> Fig. 1 is an overall external view of a dry suit in a state where a person is dressed, Fig. 2 is a detailed view of a part of a suit neck partly broken, and Fig. 3 is a detailed view of a part of a suit wrist partly broken away. .

Along the inner periphery of the neck 110 of the dry suit 100,
1 is formed. The expansion / contraction portion 111 has an annular hermetic space S independent of the other, and a connection port 112 for filling and discharging the fluid projects from the hermetic space S to the outside of the neck portion 110. The swelling fluid is sealed in or discharged from the airtight space S via the connection port 112. The expansion / contraction section 111 can be made of elastic rubber or the like. Of course, the expanding / contracting portion 111 may be formed integrally with the neck 110 using the same material, or may be formed separately and attached to the inner periphery of the neck 110 later. The outer surface of the expansion / contraction section 111 may be covered with a material that is comfortable for the human neck 210. The connection fitting 112 is made of metal or plastic, has a check valve for the fluid once introduced, and can discharge the fluid inside by hand if necessary.
Further, when the pressure in the hermetic space S exceeds a certain level, fluid does not enter the connection fitting 112 (for example, the connection fitting 11).
2), and a safety mechanism can be provided. Further, a fluid discharge port may be provided separately from the connection port 112.

The fluid to be sealed in the expansion / contraction section 111 is, for example, a liquid such as water,
Alternatively, it is a gas such as air. The injection can be easily performed by, for example, using a cassette in which air or water is pressure-filled and fitting the cassette into the connection fitting 112. When air is used, air may be introduced into the expansion / contraction section 111 using a diving air cylinder.

By enclosing the fluid in the expansion / contraction section 111, the expansion / contraction section 111
Bulges to ensure close contact with the periphery of the human neck 210. In addition, in a state where the fluid is removed from the expansion / contraction section 111, the expansion / contraction section 111 does not press the human neck 210, so that the user does not feel discomfort or pressure. In addition, it becomes easy for the user to insert the head through the suit neck 110, and the work of putting on and taking off the dry suit 100 becomes very easy.

As shown in FIG. 3, the expansion / contraction portion 1 similar to the expansion / contraction portion 111 is used.
21 may also be formed on the wrist 120 of the dry suit 100.
That is, the expansion / contraction portion 121 which forms an annular airtight space S independent from the others is formed inside the dry suit wrist portion 120 through which the human body wrist portion 220 passes. Then, a connection port 122 is provided in the same manner as the connection port 112 for discharging and filling the fluid. By forming the bulging part 121 also in the suit wrist part 120 in this way,
Water can be reliably prevented from entering the wrist. In a state in which the fluid is extracted from the expansion / contraction section 121, the wrist 220
, So that the dry suit 100 can be inserted and removed very easily.

FIG. 4 is a cross-sectional view showing the configuration when the expansion / contraction portions 111 and 121 are formed very simply. That is, a rubber tube or the like is used as a constituent material of the expansion / contraction portions 111 and 121, and this is
Glue along the inside of the neck 110 and wrist 120. Of course,
A connection fitting 112 (122) is attached to the tube in advance, and the connection fitting 112 (122) is passed through the tube so as to protrude outward during bonding. Since it is only necessary to bond the tube-shaped bulging portion 121, the configuration can be simplified.

<Effects> According to the diving dry suit according to the first aspect, the present invention has the above-described configuration, and a dedicated connection to the hermetic space S of the expansion / contraction section 111 provided along the inner periphery of the suit neck 110. Jig 1
Easy and quick expansion and contraction by filling fluid from 12
111 can be inflated, whereby the dry suit can be kept in close contact with the human neck 210 and water can be reliably prevented from entering. Moreover, the adhesion can be ensured in an appropriate state irrespective of variations in the thickness of the user's neck and the like. Also, by discharging the fluid from the expansion / contraction section 111 when attaching / detaching the suit, the human head can be smoothly passed through the suit neck 110, which is very convenient, workability is good, and the user dislikes it. Disappears. Also, even when wearing a suit, by extracting the fluid from the expansion and contraction part 111 until diving, without making the neck feel cramped,
A comfortable state can be maintained.

Further, the expansion / contraction section 111 provided on the inner periphery of the suit neck 110
For the airtight space S, a dedicated connection port 112 is provided separately from a system such as an air supply valve that supplies air into the body of the dry suit 100, and a fluid is sealed from the dedicated connection port 112. , So that the suit neck 110
The expansion and contraction of the expansion / contraction section 111 can be performed independently of the large-volume air supply / exhaust operation and the state of the body of the dry suit 100, and therefore, at any time,
It can be done anywhere, easily and quickly in a short time.

In addition, since the hermetic space S of the expansion / contraction portion 111 provided on the inner periphery of the suit neck 110 is an airtight space independent of others, it is not affected by the volume of another space or the like inside the suit body. In addition, air and the like can be quickly sealed and discharged into the space S in an independent state, and since the space is an airtight space, a reliable operation is ensured without air or the like to be sealed leaking to the surroundings.

According to the second feature of the present invention, in addition to the function and effect of the first feature, the same effect as that of the first feature is obtained in the wrist portion 120 of the dry suit 100. This makes it very easy to insert and remove the human wrist 220, and also reliably prevents water from entering.
