Description

The present invention relates to a hat including a head-mounted part and an eaves part.

Conventionally, the eaves portion of a hat has been devised to reduce its weight as much as possible by forming an opening in the core material as shown in Patent Document 1. Such an opening was also used as a wind vent to prevent the hat from being blown away by the wind.
Further, as shown in Patent Document 2, the eaves portion is generally integrated by sewing an upper cloth, a core material, and a lower cloth. When the core material has an opening as in Patent Document 1, it is difficult to sew and integrate the upper cloth, the core material, and the lower cloth. In addition, when the top cloth, the core material, and the bottom cloth are sewn together in the eaves part having an opening in the core material, the needle hole formed near the opening becomes a stress concentration point and causes damage to the core material. was also In particular, when a material that is resistant to plastic deformation is used in order to prevent the shape from collapsing, such damage is likely to occur.

According to the first aspect of the invention, by directly integrating the upper and lower fabrics, the upper and lower fabrics are not only prevented from moving relative to each other, but also the holding force between the upper and lower fabrics allows the upper and lower fabrics to be held together with the core material. relative movement can be blocked.
Since the upper cloth and the lower cloth are integrated using the openings, there is no need to form pinholes in the core material, and therefore damage to the core material due to stress concentration can be suppressed or prevented.

As in claim 2 or 3, it can be applied to a cap that covers the head or a cap that does not cover the head, such as a sun visor.

Furthermore, as in claims 4 to 6, since the upper and lower fabrics can be integrated by means of sewing, welding, adhesion, etc., appropriate means corresponding to the properties of the upper and lower fabrics are not affected by the material of the core material. The upper and lower fabrics can be integrated with .

Moreover, according to claim 7, the opening of the core material can be used as an opening for venting the wind, and the accidental scattering of the cap by the wind can be reduced.

In the present invention, when considering the influence of the stretchability of the upper and lower fabrics on the integrity of the upper and lower fabrics and the core material, the holding force of the core material by the upper and lower fabrics and the slip tolerance of the upper and lower fabrics in the plane direction of the core material need to consider.
Regarding the holding force, the shorter the distance between the edge of the opening and the integrated position of the upper and lower cloths, the stronger the upper and lower cloths can be pressed against the peripheral edge even with a slight elastic strain, and the stronger the holding force can be developed. . In addition, when considering the slip tolerance, the closer the integrated position of the upper and lower fabrics is to the opening peripheral edge, the smaller the allowable range of relative movement between the core material and the upper and lower fabrics. As a result, by adopting the eighth aspect, the relative movement between the core material and the upper and lower cloths can be made the smallest integrated area or length.

The hat includes a head-mounted part 1 and an eaves part 2. - 特許庁The head-mounted part 1 may be a bag-like one that covers the head as shown in the figure, or a U-shaped one like a headband that holds both sides of the head. can be anything.
The canopy portion 2 may be one that protrudes to the front as shown in the figure, or one that protrudes around the entire head circumference.
The eaves portion 2 is integrated with the head-mounted portion 1 by conventionally known means.

The canopy portion 2 includes a plate-like core material 6 , an upper cloth 2 a and a lower cloth 2 b that vertically sandwich the core material 6 , and a rim cloth 2 c that covers the outer peripheral edge of the core material 6 .
The core material 6 is made of a non-foamed plastic sheet and has a crescent shape in plan view. The upper cloth 2a, the lower cloth 2b, and the edge cloth 2c are formed into a bag shape by stitching the outer peripheries of the upper and lower cloths 2a, 2b with sewing lines 3a, 3b.
Openings 6a, 6b, and 6c are formed in the core member 6 at the left, right, and central portions, respectively.
These openings 6a, 6b, 6c are for reducing the weight of the core material as much as possible. integrated.
At the inner peripheries of the openings 6a, 6b, 6c, the mutually facing regions of the upper cloth 2a and the lower cloth 2b are directly sewn together by stitching lines 4a, 4b, 4c.
In this way, the peripheries of the openings 6a, 6b, 6c can be tightly sandwiched between the upper and lower cloths 2a, 2b, thereby realizing the integration of the upper and lower cloths 2a, 2b and the core material 6. As shown in FIG.
According to this embodiment, the upper cloth 2a and the lower cloth 2b can be directly integrated, and not only can the upper and lower cloths 2a and 2b be prevented from moving relative to each other, but also the clamping force between the upper and lower cloths 2a and 2b can be used. , the relative movement between the upper and lower cloths 2a, 2b and the core material 6 can be prevented.
Further, there is no need to provide a needle hole in the core material 6, thereby suppressing or preventing breakage of the core material 6 due to stress concentration.
In addition, the openings 6a, 6b, 6c of the core member 6 can be used as openings for venting the wind, thereby reducing accidental scattering of the hat due to the wind.
