DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a semi-dry suit worn in all marine sports such as surfing and wind surfing when the water temperature is low.

[0002]

2. Description of the Related Art There are two types of dry suits: a complete dry suit for completely waterproofing a wearer, such as a cold weather waterproofing suit for marine accidents, and a semi-dry suit for use in marine sports such as surfing. Covers the latter. In recent years, the rise of marine sports heat has transformed marine sports into all-season sports.
For this reason, various demands for semi-dry suits, such as waterproofness, heat retention, movability (movability), and ease of attachment / detachment, are increasing.

Conventionally, a semi-dry suit has a detachable opening,
Although a waterproof fastener is used, this waterproof fastener requires a lot of trouble in sewing and is fragile and inferior in flexibility, so there is a problem in mobility. On the other hand, as a material of a fabric having elasticity and waterproofness, for example, there is an improvement of neoprene rubber, which has been attracting attention as a material of a semi-dry suit. As a result, there has been proposed a semi-dry suit which does not use any waterproof fasteners in the attachment / detachment opening, that is, which has an opening and contractible opening at the neck of a vertically integrated semi-dry suit and which can be attached / detached from this opening. In addition,
Since the waterproofness of the neck portion is reduced unless the neck portion is in close contact with the periphery of the neck portion, the inner circumference of the opening of the dry tooth neck portion is substantially the same size as the circumference of the wearer's neck. Nevertheless, said material can be stretched to almost three times its shoulder circumference, so that the waterproofness of the collar (opening) and the wear of the wearer from the opening can be achieved without the use of waterproof fasteners. It allowed the fuselage to enter. Here, the shoulder circumference means, in order from one shoulder, the chest, the other shoulder,
Then, it refers to the outer periphery when returning to one shoulder point again via the back.

[0004]

However, a conventional suit which is configured to be detachable from the opening of the neck portion of the suit, even if the stretch ratio of the material is improved, when actually worn, firstly. The wearer must keep the removable opening expanded (extended) to about three times the size of the shoulder around his or her neck, but maintaining this state requires considerable force. , So it is not easy to put on and take off the suit,
There was a problem that it was difficult to use, especially for the weak.

[0005] In addition, as the rate of elongation of rubber or the like increases, the material may be plastically deformed (extended) as the number of times of elongation increases. There has been a problem that the contraction force of the neck portion is weakened, and the waterproofness tends to decline.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a semi-dry suit which can be easily attached and detached, has high waterproofness, and is hardly plastically deformed even when used for a long time.

[0007]

In order to achieve the above-mentioned object, a semi-dry suit according to the present invention is made of a stretchable and waterproof cloth material, and is attached to and detached from the upper and lower integrated suit part by a collar. The characteristic is that the semi-dry suit having the elastic opening of the above is improved. That is, the normal length of the inner circumference of the opening is 40 to 60% of the circumference of the shoulder, and a holding piece having a through hole is provided around the opening of the suit. The through hole can be fitted to the edge of the opening, and the holding piece can be in close contact with the periphery of the folded opening.

[0010] Preferably, a temporary fixing portion for holding the folded opening is provided at the neck portion.

[0009]

[Action] The opening for attachment and detachment is approximately 1.7 times to 2.5 times the normal size.
Stretch twice to accommodate the wearer's torso. The edge of the opening is wrapped around the neck of the wearer and the excess is folded. This folded state is held via the temporary fixing portion. Next, when the holding piece is extended slightly larger than the outer periphery of the head and lowered, and fitted to the edge of the opening, the holding piece contracts the edge of the opening and comes into close contact with the periphery of the neck.

[0010]

An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the dry suit has a vertically integrated suit portion 1, and a neck portion 10 is provided with an opening 10 a for elastic attachment and detachment. Insert from your toe to your neck and wear. As shown in FIG. 2, a base end (base of a triangle) 22 of the holding piece 2 having a substantially isosceles triangle shape is sewn on the back surface of the suit portion 1. As the material of the suit part 1 and the holding piece 2, a cloth having high elasticity and waterproofness, for example, neoprene rubber having about twice the elasticity is used.
The cost can be reduced without the need for double stretching force.

First, the suit 1 will be described in detail. The length of the inner periphery of the opening 10a at the normal time (when contracted) is 40 to 60% of the length around the shoulder which is the inner periphery at the time of attachment and detachment (when extended).
It is. As shown in FIG. 1, one end of the temporary fixing tapes 3, 3 which are temporary fixing portions are attached to the neck portion 10, and the temporary fixing tapes are attached to the other end (free end) of the temporary fixing tape. An interval is provided so as to be lockable by the provided surface fasteners 31, 31.

As shown in FIG. 2 and FIG.
Fasteners 16, 16 are attached in a substantially V-shape from near the back side of both shoulders to the groove. Since the fastener 16 is for locking the holding piece 2 to the suit part 1, it is not particularly required to be waterproof. Further, by disposing the fastener 16 and a fastener 26 to be described later that is a pair with the fastener 16 in this manner, the burden on the fastener when the body is moved can be reduced, so that a flexible thin fastener (for example, YKK Corporation) Product name 5VC PT19-P
A-DIVE) can be used. For this reason, the discomfort of the fastener is extremely reduced and the movement of the shoulder is improved, so that the mobility is also improved.

On the grooving portion of the suit portion 1, plastic snap buttons (recesses) 17,... Are arranged at intervals in a V-shape.

Next, the holding piece 2 will be described in detail. Figure 2
As shown in FIG. 1, the holding piece 2 is an approximately isosceles triangular flat fabric 20 having a size covering from the vicinity of the back side of both shoulders to the groove portion, and the through hole 21 protrudes cylindrically in the middle. It is formed. The inner circumference of the through hole 21 is normal (when contracted)
The length is substantially the same as the circumference of the neck, and is substantially the same as the outer circumference of the head when expanded (extended) for attachment and detachment.
The ratio between the normal state and the extended state of the through hole 21 in a standard wearer is about 1: 1.4.

The hypotenuse portions 23, 23 of the triangular flat fabric 20
, Fasteners 26, 26 which can be engaged with the fasteners 16, 16 provided on the suit part 1 are attached.

A plastic snap button (convex portion) 27,... Is provided at the front end portion 24 of the flat fabric 20, and the snap button (recess portion) provided on the suit portion 1 is provided.
17 and can be locked.

Next, the reason why the lengths of the inner periphery of the telescopic opening 10a at normal time and at the time of extension are determined as described above will be described. As a result of repeated experiments, the applicant has found that it is desirable to make the length as follows (however, in a standard wearer of medium and medium height, the ratio of the circumference of the neck circumference and the circumference of the shoulder circumference is not so large. , About 1 to 3).

If the length of the inner periphery of the opening 10a in the normal state is the length of the shoulder required for attachment and detachment, the attachment and detachment of the suit 1 becomes extremely easy. However, since the length obtained by subtracting the length around the neck from the length of the inner circumference of the opening 10a at the time of normal operation is largely left, the surplus portion must be folded around the neck, and there is a possibility that water will be flooded from this folded portion. Becomes larger. Therefore, considering the two requirements of ease of attachment and detachment and waterproofness, when the normal inner circumference of the opening 10a is less than 40% of the circumference of the shoulder, the waterproofness increases, but the opening 10a is not Since the force required for elongation increases, detachment is not easy. On the other hand, if it exceeds 60%, the ease of attachment / detachment will be high, but the folded portion 10b will be too long and the waterproofness will be reduced. Therefore, if the length of the inner circumference of the opening 10a at normal time is 40 to 60% of the circumference of the shoulder, the two requirements of ease of attachment and detachment and waterproofness are simultaneously satisfied.

Next, a method for mounting the semi-dry suit according to the present embodiment will be described. First, as shown in FIG. 1, the wearer expands the opening 10a of the collar neck portion 10 and inserts a torso (not shown) from the toe to the neck. Normally, the size of the opening 10a is 40 to 60% of the circumference of the shoulder, so when it is extended to about 2.5 to 1.7 times the size of the normal, it becomes the size of the shoulder and can be easily attached and detached. Was.

Next, as shown in FIG. 2, the edge of the opening 10a is wound around the neck so as to be in close contact therewith.
The surplus folded portion 10b is folded, and this state is changed to the hook-and-loop fasteners 31,
31 are held together by locking.

Next, the holding piece 2 hanging on the back side
From the head, and as shown in FIG.
Is fitted to the edge of the opening 10a. Since the cylindrical through-hole 21 shrinks to a normal size, the through-hole allows the edge (neck portion 10) of the opening 10a to come into close contact with the periphery of the neck.
At this time, the ratio between the normal state and the extended state of the through hole 21 is about 1
Since the ratio is 1.4, even a weak person can easily fit the through hole into the edge of the opening 10a, and the through hole 21 is unlikely to be plastically deformed even if used for many years.

Finally, the fasteners 16 and 26 and the snap buttons 17 and 27 provided on the suit portion 1 and the holding piece 2 are respectively engaged (FIG. 3). This allows
The installation of the semi-dry suit is completed. Fasteners 16,
26 and the snap buttons 17, 27, the holding piece 2
Is tightly hooked to the suit part 1 so that the holding piece does not turn over or move left and right even during exercise, and the waterproof performance is also improved. Also, when taking off the semi-dry suit, the order of mounting should be reversed.

The holding piece 2 is not necessarily required to be a triangular flat fabric 20 as in the above-described embodiment, but may be provided with a through-hole 21. In the case of a cylindrical shape as described above, , The range of adhesion to the neck circumference is widened, and the waterproofness can be enhanced. In addition, if the tubular portion is formed longer and folded to be doubled, the waterproofness can be further enhanced. .

Further, since the snap buttons 17 and 27 are made of plastic, rust due to salt is prevented, and locking and dismounting can be performed more smoothly than in the case of metal.

As shown in FIG. 2, the temporary fixing tape 3 only needs to hold the folded portion 10b folded around the neck, and the hook-and-loop fastener 31 is formed in a belt shape, and this is attached to the periphery of the collar neck portion 10. May be partially or annularly mounted, or each of the paired snap buttons may be mounted at intervals.

As means for hooking the holding piece 2 to the suit portion 1, fasteners 16 and 26 and a snap button 1 are provided.
Only one of 7, 27 may be used, or a hook-and-loop fastener may be used instead.

In the above embodiment, a part (22) of the holding piece 2 is provided integrally with the suit part 1, but it may be configured to be separable. When separated, the holding pieces 2 having the same shape and different colors can be mounted on the same suit portion 1. For this reason, it is possible to enjoy different aesthetics at a cheaper price than having a plurality of dry suits of different designs. Also, the holding piece 2
When either the suit part 1 is damaged, only the damaged part needs to be replaced, which is economical.

[0028]

According to the present invention, since the length of the inner circumference of the opening at normal time is set to 40 to 60% of the circumference of the shoulder, it is easy to put on and take off and has high waterproofness, and it can be used for a long time Difficult to plastically deform. Further, since the through hole of the holding piece may have a small shrinkage ratio, it is difficult to be plastically deformed, and the waterproof property of the holding piece does not deteriorate even after long-term use.

Further, by providing the temporary fixing portion, the holding piece can be easily fitted into the opening, so that attachment and detachment can be further facilitated. Further, since no waterproof fastener is used, the processing cost is reduced and the mobility (movability) is improved.
