[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a waterproof and stretchable swimming cap.

[0002]

2. Description of the Related Art A conventional swimming cap made of silicone rubber or soft synthetic resin having waterproofness and elasticity is molded in a semicircular shape whose outer peripheral edge is curved outward and convex when viewed from the front. The shape of the opening is narrower as the opening is wider and closer to the upper end. Also, above the width of the lower end,
Two wide half-surfaces are opposed to each other, and an opening at the lower end is provided.
Japanese Patent Laid-Open No. Hei 2-2
64673, JP-A-5-3214, etc.
It is shown. Of these, JP-A-2-26473
In the case of the publication, the outer rims of the halves on both sides are directly joined
And those described in JP-A-5-3214.
The top, front, and
Integrally formed through a uniform width middle section consisting of a rear face
Have been. However, the human head is on the face side or behind
The hair that passes beneath the ears when viewed from the temporal or temporal side
Since the upper part is wider than the hairline, when such a swimming cap is worn, the upper half part may not be in close contact with the head and a gap may be formed between the upper part and the head. Also the human crown
The part is relatively flat, but the top of the conventional swimming cap is
Due to the very small curvature, the sheet in this area is flat
The sheet is pulled in a plane, and the stretching ratio between the inner and outer surfaces of the sheet is
It is very different, and as a result,
Lateral wrinkles occur, which not only increases the water resistance, but also makes the appearance unsightly. Moreover, the top of the hat that was pulled strongly
The restoring force is greater on the part than on the other parts,
Is raised to the center, so the hat is easy to take off
There are also disadvantages. Also, if you try to forcibly attach this swimming cap to your head, you will feel a feeling of pressure when wearing it,
It is easy to slip up and take off while swimming.

[0003]

[Problems to be solved by the present invention] The purpose of the present invention is to adhere to the head without any difficulty, to prevent the formation of voids and wrinkles, to have a good appearance, to suppress water resistance, and to feel a feeling of oppression when worn. It is an object of the present invention to provide a swimming cap that does not cause a risk of coming off during use.

[0004]

Means for Solving the Problems] swimming cap of this invention, in order to achieve the above object, a silicone rubber or a soft synthetic resin having a waterproof property and stretch the material, under the opening side
A half-face part having an outer peripheral edge whose upper part bulges wider than the edge
Are opposed to each other, excluding the opening of these half-surface portions
An intermediate part is installed integrally between the outer peripheral edges and crosses the width of the half-face part.
Insert the width of the intermediate part from the opening at the lower end to the upper end.
It gradually forms wider .

[0005]

The narrow opening prevents slippage and ingress of water during use, and the outer peripheral edges of the pair of half-surface portions are positioned closer to the lower edge of the opening.
The upper part of the face bulges widely, and the width of the middle part between the half face parts is increased toward the upper end part, so that the face side or
When viewed from the occipital side or from the temporal side, it adapts to the shape of the head slightly wider toward the top of the hair than the hairline, closely adheres without gaps, and furthermore, the stretch ratio of the inner and outer surfaces near the top is
The difference is kept small, the restoring force of each part is made uniform, and the feeling of pressure on the head is prevented.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. In FIG. 1, the swimming cap is made of a waterproof and stretchable material whose main material is silicone rubber or soft synthetic resin, and a pair of left and right half surfaces 4, 4 ';
And an intermediate portion 5. The pair of half-surface portions 4, 4 'are opposed to each other with a gap therebetween, and are located between the lower edge of the swimming hat and the opening 1 side.
The outside convexly curved so that the upper part swells widely
Each has a peripheral edge 3, 3 ' . That is, the width of the half-surface portions 4, 4 ′ along the depth of the head of the swim hat wearer is slightly narrower near the opening 1 than near the upper end 2.

Further, as shown in FIG.
Is inclined in the opposite direction with a gap gradually increasing from the opening 1 toward the upper end 2 so that the width 1 ′ of the gap on the upper end 2 is wider than the width 1 of the gap 1 on the opening 1 side. Are facing each other. Then, close the gap between the half-surface portions 4 and 4 '.
The outer peripheral edge of the intermediate portion 5 excluding the openings 1 of the half surface portions 4 and 4 '
It is erected integrally between 3, 3 ' . Therefore, half-surface portions 4, 4
', The width of the middle part 5 intersecting the width of
Is the width of the middle part 5 along the width of the head seen from the rear,
Formed so that it gradually widens from opening 1 toward upper end 2
Ru is.

When this swimming cap is formed, the thickness of one end is equal to the width 1 of the gap on the opening 1 side, and the thickness of the other end is equal to the width 1 'of the gap on the upper end 2 side. A raw material such as silicon rubber or soft synthetic resin in a molten state is coated on the outer surface of a tapered plate body having a planar shape curved outwardly convex so as to bulge from one end to the other end. This is solidified by cooling and molded.

[0009]

[Effect of the Invention] The swimming hat of the present invention has a pair of half
The width of the upper part of the surface is wider than the width of the lower edge on the opening side
And the middle part that intersects the width of the half
The width gradually increases from the opening at the lower end to the upper end.
So that it can be viewed from the front or
Even when viewed from the side, the upper part is adapted to the shape of the head which is wider than the hairline part passing under the ear, and it fits comfortably on the head to the upper half when wearing it, There is no fear that a gap is generated between the head and the head . Also located near the crown
The inner and outer surfaces of the intermediate and half surfaces
In addition, since the difference in stretching ratio between the inner and outer surfaces can be small, wrinkles can be prevented, so that not only is there no risk of impairing the appearance, but also the resistance to water increases when swimming and the speed increases. There is no worry about falling.

In addition, an extremely large restoring force acts on the top.
Equally restored on each part based on the elasticity of the material
Due to the force, the left and right halves are pulled up to the center.
As a result, the hat can be prevented from coming off. Also,
The outer edge of each half is curved so that it bulges from the opening toward the upper end, so that it fits snugly
Even if it is formed, it does not give an uncomfortable feeling of pressure on the head when worn, it is in close contact with the head with appropriate pressure, and the opening is formed narrower than near the upper end, so wear it There is no fear of slipping inside and falling off the head, and water can be prevented from entering the inside.
