Description

Swimming suit with water intrusion suppression part

technical field

The present invention relates to a swimsuit having a water intrusion suppressing portion that suppresses intrusion of water from a chest. The present invention also relates to a swimsuit having a water ingress suppressing portion that prevents intrusion of water from the chest.

Background technique

In the field of swimwear, especially swimsuits for swimming competitions, a type of swimwear has begun to be developed using fabrics, such as plain weave, which are lighter, have less water absorption and have less resistance to water , A swimsuit of the type that comes to cover most of the body. The swimsuit is not easy to stretch, so it has functions such as maintaining the body shape of the swimmer.

For example, Patent Document 1 discloses a garment having: a base layer having a torso portion that covers at least a portion of a person's torso when worn, and is formed of a stretchable, stretchable material; Strips, which are glued on the outer surface of the above-mentioned base layer, said garment being, for example, a swimming suit.

Although the above-mentioned swimsuit covers the pectoralis major to the ankle, especially in breaststroke and other swimming methods, when performing movements such as stretching the arms and tightening the armpits, water may soak in from the chest. situation, especially in players with well-developed pectoralis major muscles. Since the resistance of water increases when water enters from the chest, and the swimming speed may slow down, it is preferable to improve in the world of swimming competitions in which hundredths of a second are competed.

As a technology to deal with the problem of water intrusion into the swimsuit, Patent Document 2 discloses a swimsuit characterized in that gaps are formed between the chest and breast space, the back and lumbar region, etc., and the surface of the human body when worn. The inner part of at least a part of the fabric is filled with an elastomeric polymer in a shape along the surface of the human body. However, since the swimsuit described in Patent Document 2 is a swimsuit that prevents the void in the chest by the filling part, even if it can prevent the void in the chest when it is still, it cannot follow the swimmer's intense body movement and muscle expansion. , so that the intrusion of water cannot be effectively suppressed.

In addition, Patent Document 3 discloses a swimsuit comprising: a material body formed of stretchable knitted fabric; and a stretchable material sheet fixed to the material body and having the following size and shape, The dimensions and shape are configured to at least partially cover the region between the anatomically higher points of the user's body. However, the swimsuit disclosed in Patent Document 3 is a swimsuit that presses the protruding part of the body by increasing the tension around the abdomen of the swimsuit, and is not a swimsuit aimed at suppressing water ingress from the chest.

In addition, Patent Document 4 discloses a swimsuit for swimming competitions for women, which is a swimsuit for women sewn from various stretchable fiber fabric materials or film fabric materials, and is characterized in that it has a Constriction and rectification structure and drainage structure, the said constriction and rectification structure is composed of tiny ridges arranged in the direction parallel to the water flow during swimming on the part facing the water flow during swimming, and the ridges are composed of Elastic resin materials such as chlorinated vinyl resin, synthetic rubber, polyurethane, and silicon are integrally formed on the surface of the fabric in such a way as to closely adhere to the fibers of the fabric. The vicinity of the opening where water enters is sewn with stretchable mesh fabric.

However, in the women's swimming competition swimsuit described in Patent Document 4, the "compression rectification structure" is a structure for the purpose of chest rectification, and the "drainage structure" is a structure for draining water immersed in the swimsuit. , so it is a structure that allows water intrusion from the chest in a sense, but not a structure that aims at suppressing water infiltration from the chest.

Detailed ways

Hereinafter, the swimming suit of this invention is demonstrated in detail using drawing.

FIG. 1 is a front view of an ankle-length swimsuit as one form of the swimsuit of the present invention, and FIG. 2 is a left side view of the ankle-length swimsuit.

As the cloth of the swimsuit of the present invention, although the cloth that is usually used as a swimsuit can be used, such as knitted fabrics, knitted fabrics, etc., it is preferably knitted fabrics, especially plain weave fabrics, for example, can be used by Speedo International A plain weave fabric comprising 70% by mass of nylon and 30% by mass of polyurethane supplied by Limited under the name of LZR Pulse (trademark).

In this specification, the neckline ranges from a shallow type that covers up to the base of the wearer's neck to a deep type that exposes a large part of the wearer's collarbone. The neckline is not particularly limited as long as it contributes to suppressing the intrusion of water from the chest, and it may be a structure commonly used in the field of swimwear, but it is preferably a stretchable structure, especially a rubber part.

In the present invention, the cuff portion may have a structure commonly used in the swimwear field, for example, a stretchable structure, for example, may have a rubber portion.

In this specification, the "first water ingress suppressing part" (the first water ingress suppressing part 3 in FIGS. 1 and 2 ) refers to a member that suppresses water intrusion from the vicinity of the pectoralis major muscle of the neckline during swimming. In addition, the term "inhibition of water intrusion" includes prevention of water intrusion unless otherwise specified.

The first water intrusion suppression part 3 is configured to connect the left and right cuffs 2, and, compared with the case without the first water intrusion suppression part 3, stretches the fabric of the swimsuit by 10%. The tensile strength shall be increased by at least 0.2N. By satisfying the above conditions, even when the wearer stretches his arms and tightens his underarms in a swimming method such as breaststroke, the first water intrusion suppression part 3 can be closely attached to the body, thereby preventing water from entering. Dip into the chest.

Although in existing swimsuits, the phenomenon of preventing water from infiltrating from the chest during wearing is used as an object, and in many cases the neckline is stretchable, but only by not making the wearer feel uncomfortable when taking it off and wearing it. Make the neckline stretchable within the uncomfortable range, especially in swimming methods such as breaststroke, when you stretch your arms and tighten your underarms, etc., there will be a large gap in the chest area, and water ingress cannot be effectively suppressed. into the gap.

In the swimsuit of the present invention, by disposing the first water intrusion suppression part 3 to connect the left and right cuff parts 2, it is possible to effectively suppress the phenomenon of water intrusion from the chest. Compared with the case where the first water intrusion suppressing portion 3 is not provided, the tensile strength of the fabric of the swimsuit when stretched by 10% can be increased by at least 0.2N.

In the present invention, the reason why the tensile strength at 10% elongation is taken as an object is that, in general, swimwear is designed so that the fabric between the left and right cuffs is stretched by about 10% when worn.

In addition, it is preferable that the first water intrusion suppressing portion 3 passes through the vicinity of the neckline portion 1 .

Since the first water intrusion suppression part 3 used in the present invention is compared with the case without the first water intrusion suppression part 3, the tensile strength of the fabric of the swimsuit can be increased by at least 0.2N when stretched by 10%. Therefore, even when the wearer stretches the arms and tightens the underarms in swimming methods such as breaststroke, it can be tightly attached to the body, thereby preventing the intrusion of water into the chest.

In order to effectively prevent the intrusion of water into the chest, the first water intrusion suppression part 3 used in the present invention is preferably, compared with the case of not having the first water intrusion suppression part 3, the cloth of the swimsuit is stretched by 10 % increase in tensile strength by at least 0.3N, more preferably by 0.4N.

When considering the ease of taking off and the difficulty of breathing when wearing it, the first water intrusion suppression part 3 used in the present invention is preferably made of a swimsuit as compared with the case without the first water intrusion suppression part 3 . The tensile strength of the cloth when elongated by 10% increases by 3.0N at the maximum, more preferably 2.0N at the maximum, and preferably 1.5N at the maximum.

Furthermore, in the case where the neckline 1 has stretchability, intrusion of water from the chest is further effectively suppressed.

The tensile strength when the fabric of the swimsuit is stretched by 10% can be measured according to the B method of "8.12 Tensile strength and elongation" of JIS L 1096. Although it is based on JIS L 1906 in principle, the differences are as follows.

Sample: length 15cm×width 10cm

*In the case of a sample having the first water intrusion suppression part, prepare a sample with a width of 5 cm x a length of 15 cm on the left and right with the first water intrusion suppression part as the center.

Clamping end interval: 10cm

Tensile speed: 100mm/min

Determination: three times stretching to 30% elongation, and adopt the value measured for the third time

As a measuring instrument, a constant velocity extension type tensile tester such as RTC-1210A manufactured by ORIEN TEC can be used.

The shape of the first water intrusion suppression part 3 is not particularly limited as long as it is arranged to connect the left and right cuff parts 2 and prevent water from intruding into the chest. For example, as shown in FIGS. 3 and 4 As shown, it can have a shape selected from a substantially linear shape, a substantially arcuate shape, a substantially V-shape, a substantially inverted V-shape, a substantially U-shape, or a combination of these shapes.
