CONSTITUTION:A cap 1 for swimming is put on so as to be tightly fitted in a head part H of a swimmer S in making a part with hair into a center, and it is equipped with a flow rectifying part 11 extended from an approximate head top part h1 up to a rear head part h2 and, further, up to a neck nape N. For the flow rectifying part 11, the part corresponding to the rear head part h2 from the approximate head top part h1 is formed to be gradually thick from the head top part h1, and it is formed so as to stretch along the neck nape N as it is and to be gradually thin toward the neck nape N. Then, the flow rectifying part 11 rectifies a relative water flow W when the swimmer S swims, the resistance due to a turbulent flow or eddy flow, etc., generated in the part of the neck nape N of the swimmer S when the flow rectifying part 11 does not exist is remarkably reduced, and the swimming is made more easily.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a swimming cap, such as a cap that covers the hair part of a competitive swimmer, and a cap that is integrally formed with a swimming suit and is worn above the neck. , relates to a swimming cap such as a scuba diver's cap that is integrally formed with a scuba diver's suit, and a scuba diver's cap that is worn from the neck up.

(Prior Art) Conventionally, this type of swimming cap C, as shown in FIGS. 16 to 19, is generally formed to have a thickness of about 0.5 mm and fits tightly onto the head H of the swimmer S. It is formed like this.

[Problem to be solved by the invention]

Therefore, the contour of the head area of the swimmer S wearing such a cap C is such that the head is round and protrudes backwards, then concaves forward from there to the nape of the neck, and protrudes rearward again at the shoulder blades.

For this reason, while swimming, turbulent or eddy currents WH of water are generated along the nape N from the back of the head of the swimmer S, and from the chin J of the swimmer S along the nape of the neck, as well as complex waves. It acts as forward resistance for the swimmer.

SUMMARY OF THE INVENTION Therefore, the present invention has been developed to reduce the turbulent flow or vortex or complicated waves of water that occurs from the swimmer's head to the nape of the neck, which occur in conventional swimming caps, thereby reducing the resistance caused by the water. To provide a swimming cap capable of regulating at least part of the flow of water from the head to the nape of the neck.

(Means for Solving the Problems) In accordance with the above-mentioned object, the present invention provides a swimming cap having a rectifying section for reducing water resistance that extends from a swimmer's head to the nape of the neck when the cap is worn.

Here, the swimmer's head is not just the part with hair;
Refers to the area above the neck, including the jaw area.

Furthermore, "water resistance" refers to various resistances caused by water that impede swimmers' progress.

There are various possible positions for the rectifier, but typically, it is provided so that it extends from the back of the swimmer's head to the nape of the neck when the cap is worn, or it extends from the swimmer's chin to the nape of the neck when the cap is worn. Both of these cases are possible. Note that it is also possible to provide it at the top of the head.

The flow straightening section may be formed of a hard material, but considering that the swimmer's posture changes during swimming, it can be elastically deformed so as to absorb water resistance during swimming, and at the same time, the deformation may cause the swimmer to It is desirable to include a portion made of a material capable of regulating the relative water flow. In this case, the entire flow straightening section may be formed from such an elastic material.

Further, it is preferable that the rectifier is formed of a material having a specific gravity as close to that of water as possible. However, there is no need to be limited to such materials.

Generally speaking, materials for the rectifier section include various materials with rubber-like elasticity used in conventional swimming caps, scuba diver suits, etc., various fabric materials used in swimwear, and other suitable materials. For example, in combination with elastic materials.

[For production]

According to the swimming cap of the present invention, when a swimmer wears the swimming cap while swimming, at least a portion of the flow of water from the head of the swimmer along the nape of the neck is regulated by the water resistance reducing rectifier.

When the rectifier includes a portion made of an elastic material that can be deformed by the resistance of water during swimming so as to adjust the relative water flow during swimming, the rectifier deforms to soften the resistance caused by the water.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

1st Embodiment (See FIGS. 1 and 2) - The swimming cap 1 shown in FIGS. 1 and 2 is worn so as to fit tightly onto the head H of the swimmer S, centering on the hair area. It is equipped with a rectifying part 11 extending from the top of the head h1 to the back of the head h2 and further to the nape of the neck N.

The rectifying part 11 is formed so that a portion corresponding to the occiput h2 from the parietal part hl gradually becomes thicker from the parietal part h1, and extends along the nape N of the neck.

When looking at the rectifier 11 from behind, as shown in FIG.
It is formed so as to gradually become thinner toward the nape N.

As shown in FIG. 1, when the swimmer S swims, the relative water flow W is adjusted by the rectifier 11, and if there is no rectifier 11, turbulent flow or eddy flow would occur at the neck N of the swimmer S. The resistance caused by water resistance (water resistance) is drastically reduced, making swimming that much easier.

The main body portion 12 of the cap 1 is made of rubber, as is the case with competitive swimming caps that are already on the market, and the flow straightening portion ti is also formed integrally with the cap main body 12 from the same rubber material.

Therefore, the rectifier 11 has rubber-like elasticity, and when the swimmer is swimming,
When subjected to water resistance, it becomes slightly elastically deformed due to the resistance,
By this deformation, water resistance can be alleviated and the water flow can be adjusted extremely smoothly.

Note that a chin strap 110 may be provided from the rectifying section 11 if necessary.

In addition, the rectifier 11 is constructed by filling a bag-shaped body made of the same material as the material forming the cap body 12 with an appropriate elastic material such as a sponge having a specific gravity close to that of water so as to maintain a desired shape. It may be configured as follows.

1. Second embodiment (see FIG. 3) The swimming cap 2 shown in FIG.
In the modified example, when viewed from behind, the rectifier 21
It extends from the rear part of the ear to the nape N of the neck with almost the same width, and is otherwise the same as the swimming cap l.

Third embodiment (see Figures 4 and 5) - Figures 4 and 5
The swimming cap 3 shown in the figure covers the head 1 (and neck N) of the swimmer S while leaving the face intact, and includes water resistance reducing rectifiers 31 to 34.

The rectifier 31 extends from the back of the head h2 to the neck N, and the rectifier 32 extends from the jaw J to the neck N. The rectifiers 33 and 34 extend from the side surface of the head to the neck N.

The rectifying section 31 is formed so that a portion corresponding to the head m portion h1 to the occiput h2 gradually becomes thicker from the parietal portion hl, and extends directly to the neck portion N.

When the rectifier 31 is viewed from behind, as shown in FIG.
It is formed to become gradually thinner toward the neck N.

Although not shown, the rectifying portion 32 is also formed to become gradually thinner from the jaw portion J toward the neck portion N.

As shown in FIGS. 4 and 5, these rectifiers 31 to 34 adjust the relative water flow W when the swimmer S swims, thereby reducing water resistance and making it easier to swim.

The rectifiers 31 to 34 are also formed integrally with the cap body 35, and are made of the same material as the rubber material conventionally used in commercially available swimming caps.

Therefore, when the rectifying section receives water resistance while the swimmer is swimming, it can be slightly elastically deformed by the resistance, and this deformation can alleviate the water resistance and regulate the flow of water extremely smoothly.

Note that these flow straightening parts may be formed, if necessary, by filling a bag-shaped body made of the same material as the material of the cap body 35 with an appropriate material having a specific gravity close to that of water, such as a sponge-like elastic material, so as to maintain the desired shape. It may be configured as follows.

- Fourth embodiment (see FIGS. 6 to 1I) - The swimming cap 4 shown in FIGS. 6 to 11 is a swimming suit 40.
It is integrally formed with the water resistance and includes water resistance reducing rectifying parts 41 to 44.

The rectifier 41 extends from the back of the head h2 to the neck N, and the rectifiers 4 and 2 extend from the jaw J to the neck N, respectively. The rectifiers 43 and 44 extend from the side surface of the head to the neck N.

The rectifying part 41 is formed so that a portion corresponding to the occipital region h2 from the head vertex h1 gradually becomes thicker from the head vertex h1, and extends to the neck region N as it is.

When the rectifying section 41 is viewed from behind, as shown in FIG.
It is formed to become gradually thinner toward the neck N.

The rectifier 42 also extends from the jaw J to the neck N, as shown in FIG.
It is formed so that it gradually becomes thinner towards the end.

The rectifiers 41 to 44 are made of a flexible material that gives the shape of the rectifiers 41 to 44 to the inside of the swimsuit fabric 45 that integrally forms the cap body, suit portion, etc., and guarantees freedom of the neck.
For example, it is filled with a rubber material or a sponge-like elastic material with heat insulating properties.

The end of the portion 451 of the swimsuit fabric 45 that extends from the cap 4 to the back is hooked to the upper end of the back portion of the suit body at a hook 46.
It can be attached and detached freely.

As shown in FIGS. 9 to 11, the flow rectifiers 41 to 44 control the relative water flow along the head H to the neck N of the swimmer S when the swimmer S swims, for example from the back of the head h2 to the neck N and the jaw. By adjusting the relative water flow W from J to the neck N, etc., water resistance is reduced accordingly, making swimming easier.

When the rectifying section receives water resistance while the swimmer is swimming, it can be slightly elastically deformed by the resistance, and this deformation can soften the water resistance and regulate the flow of water extremely smoothly.

1. Fifth Embodiment (See Figures 12 to 15) - The swimming cap 5 shown in Figures 12 to 15 is a cap for scuba divers, and a suit 5 for scuba divers.

The rectifiers 53 and 54 extend from the side of the occiput h2 to the neck N.

The rectifying portion 51 is formed so that a portion corresponding to the occipital region h2 from the head vertex h1 gradually becomes thicker from the vertex h1, and extends to the neck region N as it is.

When viewed from the rear, the rectifier 51 is formed so as to become gradually thinner toward the neck N, as shown in FIG.

Although not shown, the rectifier 52 is also formed to become gradually thinner from the jaw J toward the neck N, as in the cap shown in FIG. 8, for example.

The rectifiers 51 to 54 are made of a flexible material, such as rubber, that gives the shape of the rectifiers 51 to 54 to the inside of the diaper suit fabric 55 that integrally forms the cap body, the suit part, etc., and that guarantees the degree of freedom of the neck. It is formed by filling it with material or a sponge-like elastic material with insulation properties.

As shown in FIGS. 14 and 15, the rectifiers 51 to 54 control the relative water flow from the head H of the diper D along the neck N, for example from the back of the head h2 to the neck N and the jaw when the dipper D swims underwater. Adjust the relative water flow W from J to the neck N etc.,
This reduces water resistance, making it easier to swim and providing stability in the direction of head movement.

When the rectifiers 51 to 54 receive water resistance while the Diaper D is swimming, they can be slightly elastically deformed by the resistance, and this deformation can soften the water resistance and regulate the flow of water extremely smoothly.

Note that the present invention is not limited to the above-mentioned embodiments, and can be implemented in various other ways.

For example, when the rectifying section is constructed using a filler as in the fourth and fifth examples of capacity cans (FIGS. 6 to 15), the filler portion may be detachable. .

Alternatively, the flow straightening section may be formed hollow, and the hollow section may be filled with a gas such as air, a gel-like substance, water, or the like to give the flow straightening section a desired shape.

Also, such filler material may be removable.

[Effects of the Invention] According to the present invention, the turbulent flow, eddies, and complicated waves of water that occur from the swimmer's head to the nape of the neck, which occur with conventional swimming caps, are reduced, and the resistance caused by water is reduced. It is possible to provide a swimming cap that can at least partially regulate the flow of water from the swimmer's head to the nape of the neck.

When the rectifying section includes a portion made of an elastic material that can be deformed by the resistance of water during swimming so as to adjust the relative water flow during swimming, the rectifying section deforms smoothly and deforms to soften the resistance caused by the water. Adjust the flow of water.
