Description

The present invention relates to a hat in which the crown outer material is formed into a substantially hemispherical shape by joining multiple pieces of joining fabric, and to a method for manufacturing the hat.

The crown of a baseball cap or other hat is usually formed into a roughly hemispherical shape by sewing together the side edges of several pieces of sewing fabric that have been cut into roughly isosceles triangle shapes called "renge." After the necessary parts, such as a brim and a visor, are attached to the roughly hemispherical crown depending on the type of hat, a finishing process called "molding" is carried out.

As shown in FIG. 1 of Patent Document 1, for example, the crown outer fabric of this type of hat generally consists of a left front covering part ("left front part 21" in the figure) that covers the left front part of the wearer's head, a right front covering part ("right front part 22" in the figure) that covers the right front part of the wearer's head, a left lateral covering part ("left central part 23" in the figure) that covers the left lateral part of the wearer's head, a right lateral covering part ("right central part 24" in the figure) that covers the right lateral part of the wearer's head, a left rear covering part ("left rear part 25" in the figure) that covers the left rear part of the wearer's head, and a right rear covering part ("right rear part 26" in the figure) that covers the right rear part of the wearer's head, each of which is formed from a different sewing fabric (astragalus).

However, when forming the crown outer material by sewing together the sewing fabric that is divided into the left front covering portion, right front covering portion, left side covering portion, right side covering portion, left rear covering portion, and right rear covering portion, as in the hat of Patent Document 1, there is a drawback in that as many as six pieces of sewing fabric are required to finish one crown outer material into a hemispherical shape. In particular, sewing the sewing fabric is usually done by a person operating a sewing machine, which is quite labor-intensive. The sewing work of the sewing fabric is also one of the factors that leads to an increase in the manufacturing costs of the hat.

In addition, to prevent unraveling, backing strips (see, for example, "backing strip 30" in FIG. 1 of Patent Document 1) are generally sewn to the edges of the stitching fabric that constitutes the crown outer material, i.e., the edges that are sewn to other stitching fabrics, and the stitched parts of the stitching fabric tend to be harder than the surrounding areas. For this reason, if there are multiple stitched parts on the crown outer material, there is also the problem that the wearer of the hat is likely to feel uncomfortable on the head. In particular, wearers of sports caps such as baseball caps often have short hair, and the feel of the cap is easily transmitted to the head, so it is not desirable to provide multiple stitched parts on the crown outer material of sports caps such as baseball caps.

Furthermore, while designs are sometimes applied to the outer surface of the crown outer material using embroidery or patches, the stitched parts of the crown outer material are prone to wrinkling and are difficult to flatten due to the sewing thread, and as mentioned above, they also tend to become hard, making them unsuitable locations for applying designs. For this reason, hats with stitched parts in multiple places on the crown outer material also have the disadvantage that the dimensions and placement of the designs are easily restricted.

The present invention has been made to solve the above problems, and provides a hat that has fewer joints (stitches, welds, etc.) on the crown outer material, making it possible to reduce manufacturing costs. Another object of the present invention is to provide a hat that is comfortable to wear. A further object of the present invention is to provide a hat that allows for a high degree of freedom in the dimensions and placement of the design portion provided on the outer surface of the crown outer material. And another object of the present invention is to provide a method for manufacturing this hat.

The above issues are:
A substantially triangular left front covering part for covering the left front part of the wearer's head;
A substantially triangular right front covering part for covering a right front part of the wearer's head;
A substantially triangular left lateral covering part for covering a left lateral part of a wearer's head;
A substantially triangular right side covering part for covering a right side part of the wearer's head;
A substantially triangular left rear covering part for covering a left rear part of a wearer's head;
A substantially triangular right rear covering part for covering a right rear part of the wearer's head;
A hat having a substantially hemispherical crown outer material made of a plurality of joining fabrics joined together,
At least in the crown surface,
A front covering part composed of a left front covering part and a right front covering part;
A rear covering section composed of a left lateral covering section, a right lateral covering section, a left rear covering section, and a right rear covering section,
It is composed of another joining material,
The problem is solved by providing a hat characterized in that the rear covering portion of the crown outer material is constituted by two or less layers of joining fabric.

Here, "joining" is a concept that includes not only "sewing" but also "welding". The crown outer material of a hat is generally formed by sewing together multiple pieces of sewing fabric (joining fabric) with a sewing machine or the like, but the technical scope of the hat of the present invention is not limited to sewing together the sewing fabric (joining fabric). In other words, the technical scope of the hat of the present invention also includes a configuration in which the crown outer material is formed by welding together multiple pieces of joining fabric with an ultrasonic sewing machine or the like. When the joining fabric that constitutes the crown outer material is welded with an ultrasonic sewing machine, it can be made seamless, which makes it possible to improve the appearance and comfort of the hat.

In conventional hats, the rear covering portion of the crown outer material is formed of four pieces of joining fabric divided into a left side covering portion, a right side covering portion, a left rear covering portion, and a right rear covering portion. However, by limiting the number of joining fabrics constituting this rear covering portion to two or less, as in the hat of the present invention, it is possible to reduce the number of joining points of the crown outer material. This reduces the effort required to join the joining fabrics and reduces the manufacturing costs of the hat. It is also possible to provide a hat that is comfortable to wear because there are few joining points on the crown outer material that are likely to cause discomfort to the wearer of the hat. Furthermore, it is also possible to provide a hat that has few joining points on the crown outer material that are an obstacle to applying a design portion such as embroidery or a patch, and therefore has a high degree of freedom in the size and arrangement of the design portion.

In the hat of the present invention, the rear covering portion of the crown outer material is composed of two or less joining fabrics. Therefore, there are two types of hats of the present invention: a "rear one-piece type" in which the rear covering portion of the crown outer material is composed of one joining fabric, and a "rear two-piece type" in which the rear covering portion of the crown outer material is composed of two joining fabrics.

First, the rear one-piece type of hat includes a hat in which the rear covering part of the crown outer material is made of a single continuous piece of joining fabric from the left side covering part through the left rear covering part and right rear covering part to the right side covering part.

In this hat with one rear piece, the rear covering portion of the crown outer material is formed from a single piece of joining fabric, so there is no need to join the boundary between the left side covering portion and the left rear covering portion, the boundary between the right side covering portion and the right rear covering portion, or the boundary between the left rear covering portion and the right rear covering portion, etc., in the crown outer material. This not only significantly reduces the effort required to join the crown outer material, but also significantly reduces the sense of discomfort when wearing the hat. In addition, it is also possible to suitably apply designs using embroidery or patches over a wide area of the rear covering portion of the crown outer material.

Also, as for the hat with two rear pieces,
The rear covering portion of the crown outer material is
A joining fabric that is continuous from the left side covering portion to the left rear covering portion;
A joining fabric that is continuous from the right side covering portion to the right rear covering portion;
One example is one that is composed of a total of two joining fabrics.

In this hat with two rear panels, the crown outer fabric needs to be joined at the boundary between the left rear covering part and the right rear covering part, which means one more joining point compared to the hat with one rear panel. However, there is still no need to join the boundary part of the crown outer fabric between the left side covering part and the left rear covering part, or the boundary part between the right side covering part and the right rear covering part. This not only significantly reduces the effort required to join the crown outer fabric, but also significantly reduces the discomfort felt when wearing the hat, even with a hat with two rear panels. In addition, it is possible to suitably apply designs using embroidery or patches over a wide area of the rear covering part of the crown outer fabric.

As already mentioned, in the hat of the present invention, the front covering portion (left front covering portion and right front covering portion) of the crown outer material and the rear covering portion (left side covering portion, right side covering portion, left rear covering portion and right rear covering portion) of the crown outer material are formed by different joining fabrics. The crown outer material can be formed into a substantially hemispherical shape by using at least two joining fabrics, without using six joining fabrics. However, if the joining fabrics forming the front covering portion of the crown outer material and the joining fabrics forming the rear covering portion of the crown outer material are both thick (hard, such as containing a core), the crown outer material formed by joining them together will not be a perfect hemispherical shape, but will tend to be distorted. On the other hand, if the joining fabrics forming the front covering portion of the crown outer material and the joining fabrics forming the rear covering portion of the crown outer material are both thin (soft, not containing a core), it will be difficult to impart shape retention to the crown outer material formed by joining them together.

For this reason, in the hat of the present invention,
The front covering portion of the crown outer material is made of a hard material including an interlining,
It is preferable that the rear covering portion of the crown outer material is made of a soft fabric that does not include an interlining.
This not only allows the crown surface to be formed into a beautiful hemispherical shape, but also makes it possible to impart shape retention to the crown surface.

In addition, in the hat of the present invention, the crown may be formed only from the crown outer material, but a lining (crown lining) can also be placed on the inside side of the crown outer material. This makes it possible to form the surface of the crown of the hat that comes into contact with the wearer's head from a material that feels good against the skin, further improving the comfort of wearing the hat, and to provide a ventilation space between the crown outer material and the crown lining, thereby imparting a ventilation function to the crown. However, in this case, if there are many joints in the crown lining despite the reduction in the number of joints in the crown outer material, there is a risk that the hat of the present invention will not be able to fully achieve the intended effect.

For this reason, in the hat of the present invention,
a crown lining having the same number and shape as the fabric constituting the rear covering portion of the crown outer fabric is disposed on the inner surface side of the rear covering portion of the crown outer fabric;
It is preferable to adopt a structure in which the crown lining is not joined to the crown outer material at any portion other than the peripheral edge portion.
This allows the joints in the crown lining to coincide with the joints in the crown outer material, making it possible to prevent an increase in the number of joints due to the provision of the crown lining.

Furthermore, in the hat of the present invention, it is also preferable to provide a design portion by embroidery or a patch on the outer surface of the rear covering portion of the crown outer material.

As already mentioned, if the crown outer fabric has many joints, the size and placement of the design part using embroidery or patches is likely to be limited, but the hat of the present invention has fewer joints on the crown outer fabric, allowing greater freedom in the size and placement of the design part. With the hat of the present invention, it is also possible to boldly apply a large design part to the rear of the crown outer fabric (rear covering part).

In this way, when applying a design to the outer surface of the crown,
The design part is on the crown surface,
The boundary between the left lateral covering part and the left posterior covering part,
The boundary between the right side covering part and the right rear covering part, or
It is also possible to apply the protective film across at least one boundary portion selected from the boundary portions between the left rear covering portion and the right rear covering portion.

In addition, the above problem is
A substantially triangular left front covering part for covering the left front part of the wearer's head;
A substantially triangular right front covering part for covering a right front part of the wearer's head;
A substantially triangular left lateral covering part for covering a left lateral part of a wearer's head;
A substantially triangular right side covering part for covering a right side part of the wearer's head;
A substantially triangular left rear covering part for covering a left rear part of a wearer's head;
A substantially triangular right rear covering part for covering a right rear part of the wearer's head;
A hat having a substantially hemispherical crown outer material made of a plurality of joining fabrics joined together,
In the crown outer surface,
A left side covering part composed of a left front covering part, a left side covering part, and a left rear covering part;
A right side covering part composed of a right front covering part, a right side covering part, and a right rear covering part,
It is composed of another joining material,
The left covering portion of the crown outer material is made of a continuous piece of joining fabric,
The above-mentioned problems can also be solved by providing a hat, wherein the right-side covering portion of the crown outer material is constituted by a single continuous piece of joining fabric.

This makes it possible to form the portion of the crown outer material that covers the left hemisphere of the wearer's head (left covering portion) and the portion that covers the right hemisphere of the wearer's head (right covering portion) from a single piece of joining fabric, in other words, to construct the crown outer material from only two pieces of joining fabric. In other words, it becomes possible to reduce the number of joining points of the crown outer material. This reduces the effort required to join the joining fabrics and makes it possible to reduce the manufacturing costs of the hat. In addition, it becomes possible to provide a hat that is comfortable to wear because there are few joining points on the crown outer material that are likely to cause discomfort to the wearer. Furthermore, it becomes possible to provide a hat that has few joining points on the crown outer material that are an obstacle to applying a design part such as embroidery or a patch, and has a high degree of freedom in the size and arrangement of the design part. In the following, a hat of this type may be referred to as a "left and right two-part type hat."

For hats that are divided into two parts,
The crown lining arranged on the inner side of the left covering part of the crown outer material is made of a single piece of fabric having substantially the same shape as the crown outer material of the left covering part,
The crown outer material and the crown inner material of the left covering part are not joined at any part other than the peripheral edge thereof,
The crown lining arranged on the inner side of the right covering part of the crown outer material is made of a single piece of fabric having substantially the same shape as the crown outer material of the right covering part,
It is preferable that the crown outer material and the crown lining material of the right covering part are not joined together except at their peripheral edges.

This allows the joints in the crown lining to coincide with the joints in the crown outer material, making it possible to prevent an increase in the number of joints due to the provision of the crown lining. In addition, in a hat with two separate parts, it is also preferable to provide a design by embroidery or a patch on the outer surface of the left covering part or the right covering part of the crown outer material. In addition, in a hat with two separate parts, when providing a design on the crown outer material in this way,
The design part is on the crown surface,
The boundary between the left front covering part and the left side covering part,
The boundary between the left lateral covering part and the left posterior covering part,
The boundary between the right front covering part and the right side covering part, or
It is also possible to apply the protective layer across at least one boundary portion selected from the boundary portions between the right side covering portion and the right rear covering portion.

Furthermore, the above problem is
A substantially triangular left front covering part for covering the left front part of the wearer's head;
A substantially triangular right front covering part for covering a right front part of the wearer's head;
A substantially triangular left lateral covering part for covering a left lateral part of a wearer's head;
A substantially triangular right side covering part for covering a right side part of the wearer's head;
A substantially triangular left rear covering part for covering a left rear part of a wearer's head;
A substantially triangular right rear covering part for covering a right rear part of the wearer's head;
A hat having a substantially hemispherical crown outer material made of a plurality of joining fabrics joined together,
In the crown outer surface,
a front covering part including a front half of a left lateral covering part, a left front covering part, a right front covering part, and a front half of the right lateral covering part;
a rear covering part consisting of a rear half of the left lateral covering part, a left rear covering part, a right rear covering part, and a rear covering part consisting of a rear half of the right lateral covering part;
It is composed of another joining material,
The front covering portion of the crown outer material is made of a continuous piece of joining fabric,
The above-mentioned problems can also be solved by providing a hat, in which the rear covering portion of the crown outer material is constituted by a single continuous piece of joining fabric.

This makes it possible to form the portion of the crown outer material that covers the front half of the head of the wearer (front covering portion) and the portion of the crown outer material that covers the rear half of the head of the wearer (rear covering portion) from a single piece of joining fabric, in other words, to construct the crown outer material from only two pieces of joining fabric. In other words, it becomes possible to reduce the number of joining points of the crown outer material. This reduces the effort required to join the joining fabrics, and makes it possible to reduce the manufacturing costs of the hat. In addition, it becomes possible to provide a hat that is comfortable to wear because there are few joining points on the crown outer material that are likely to cause discomfort to the wearer. Furthermore, it becomes possible to provide a hat that has few joining points on the crown outer material that are an obstacle to applying a design part such as embroidery or a patch, and therefore has a high degree of freedom in the size and arrangement of the design part. In the following, this type of hat may be referred to as a "front and back two-part type hat."

For hats with two separate sections,
The crown lining arranged on the inner side of the front covering part of the crown outer material is made of a single piece of fabric having substantially the same shape as the crown outer material of the front covering part,
The crown outer layer and the crown inner layer of the front covering portion are not joined together except at their periphery.
The crown lining arranged on the inner side of the rear covering part of the crown outer material is made of a single piece of fabric having substantially the same shape as the crown outer material of the rear covering part,
It is preferable that the crown outer material and the crown inner material of the rear covering part are not joined together except at their peripheral edges.

This allows the joints in the crown lining to coincide with the joints in the crown outer material, making it possible to prevent an increase in the number of joints due to the provision of the crown lining. In addition, in a hat with two separate parts, it is also preferable to provide a design part by embroidery or a patch on the outer surface of the front covering part or the back covering part of the crown outer material. In addition, in a hat with two separate parts, when providing a design part on the crown outer material in this way,
The design part is on the crown surface,
The boundary between the left lateral covering part and the left front covering part,
A boundary portion between the left front covering portion and the right front covering portion,
The boundary between the right front covering part and the right side covering part,
The boundary between the left lateral covering part and the left posterior covering part,
The boundary between the left and right rear covering parts, or
It is also possible to apply the protective layer across at least one boundary portion selected from the boundary portions between the right rear covering portion and the right side covering portion.

As described above, the present invention makes it possible to provide a hat that has fewer joints (such as stitching and welding) on the crown outer material, thereby reducing manufacturing costs. It also makes it possible to provide a hat that is comfortable to wear. Furthermore, it makes it possible to provide a hat that allows for a high degree of freedom in the dimensions and placement of the design portion provided on the outer surface of the crown outer material. It also makes it possible to provide a method for manufacturing this hat.

0. Hat of the Present Invention Preferred embodiments of the hat of the present invention will be described in more detail with reference to the drawings. In the following, the hat of the present invention will be described mainly using six embodiments from the first embodiment to the sixth embodiment as examples. However, the technical scope of the hat of the present invention is not limited to these embodiments, and appropriate changes can be made within the scope that does not impair the spirit of the invention.

For ease of explanation, the hat of the present invention will be described below using an example in which the sewing fabric constituting the crown outer material etc. is sewn. However, as already mentioned, the technical scope of the hat of the present invention also includes a configuration in which the joining fabric forming the crown outer material etc. is formed by welding with an ultrasonic sewing machine. Configurations in which the word "sewn" in the following description is replaced with "welding" or "joining" can also be preferably adopted.

1. Hat of the First Embodiment First, the hat of the first embodiment will be described. The hat of the first embodiment corresponds to the above-mentioned "rear one-piece type hat." Fig. 1 is a view of the hat of the first embodiment seen from diagonally above the front. Fig. 2 is a view of the hat of the first embodiment seen from above. Fig. 3 is a view of the hat of the first embodiment seen from below. Fig. 4 is a perspective view showing the hat of the first embodiment in an exploded state.

The hat of the first embodiment comprises a crown 10 (Fig. 1) that covers the wearer's head, a brim 20 (Fig. 1) that protrudes forward from the crown 10, a visor 30 (Fig. 3) that is provided in a strip along the inside of the lower edge of the crown 10, and a lining strip 40 (Fig. 3) that reinforces the stitching of the crown 10 from the inside of the crown 10. As shown in Fig. 4, the crown 10 is composed of a crown outer material 11 that forms the outer surface of the crown 10, and a crown lining 12 that is arranged along the inner surface of the crown outer material 11.

As shown in Figs. 1 and 2, the crown outer fabric 11 is made up of a substantially triangular left front covering part 11a ₁ (a substantially fan-shaped part surrounded by points C ₀ , P ₁ , and P ₂ in Fig. 2 ) covering the left front part of the wearer's head, a substantially triangular right front covering part 11a ₂ (a substantially fan-shaped part surrounded by points C ₀ , P ₁ , and P ₃ in Fig. 2 ) covering the right front part of the wearer's head, a substantially triangular left lateral covering part 11b ₁ (a substantially fan-shaped part surrounded by points C ₀ , P ₂ , and P ₄ in Fig. 2 ) covering the left lateral part of the wearer's head, a substantially triangular right lateral covering part 11b ₂ (a substantially fan-shaped part surrounded by points C ₀ , P ₃ , and P ₅ in Fig. 2 ) covering the right lateral part of the wearer's head, and a substantially triangular left rear covering part 11b ₃ (a substantially fan-shaped part surrounded by points C ₀ , P ₄ in Fig. 2 ) covering the left rear part of the wearer's head. 2 ) that covers the right rear portion of the wearer's head, and a substantially triangular right rear covering part _11b4 (a substantially fan-shaped portion surrounded by points _C0 , _P5 , _P6 in FIG. ₂ ).

As shown in Fig. 4, the crown outer fabric 11 has a front covering part 11a consisting of a left front covering part 11a- ₁ and a right front covering part 11a _{- 2} , and a rear covering part 11b consisting of a left lateral covering part 11b- ₁ , a right lateral covering part 11b- ₂ , a left rear covering part 11b-3 and a right rear covering part 11b- ₄ , which are made of different sewing fabrics. Specifically, the front covering part 11a is made by sewing together two sewing fabrics 13a and 13b, and the rear covering part 11b is made by one sewing fabric 14. These sewing fabrics 13a, 13b and 14 are connected to each other by sewing their side edges together, so as to form a hemispherical shape as shown in Fig. 1.

As already mentioned, in conventional hats, the portion of the crown outer material 11 corresponding to the rear covering portion 11b is made up of about four pieces of sewing fabric, whereas in the hat of the first embodiment, it is made up of one piece of sewing fabric 14. In other words, the rear covering portion 11b of the crown outer material 11 is made up of one continuous piece of sewing fabric 14 from its left side covering portion _11b1 through the left rear covering portion _11b3 and the right rear covering portion _11b4 to the right side covering portion _11b2 .

Therefore, in the hat of the first embodiment, as shown in FIG. 2, the sewing fabric 13a forming the left front covering portion _11a1 of the crown outer fabric 11 and the sewing fabric 13b forming the right front covering portion _11a2 of the crown outer fabric 11 are sewn together at a sewing portion _α1 , and the side edges of the sewing fabric 14 forming the rear covering portion 11b of the crown outer fabric 11 are sewn to the sewing fabrics 13 and 14 at sewing portions _α2 and _α3 , respectively. In this way, a substantially hemispherical crown outer fabric 11 can be obtained by simply sewing three portions.

Therefore, in the hat of the first embodiment, the labor required for sewing the sewing fabrics 13a, 13b, and 14 is reduced, and the manufacturing cost of the hat can be significantly reduced. Also, the number of stitched parts _α1 , α2, and α3 that tend to cause the wearer of the hat to feel uncomfortable is reduced, making it possible to improve the comfort of wearing the hat. Furthermore, the number of stitched parts _α1 , _α2 , and _α3 that are an obstacle to applying a design part using embroidery, _patches , _etc. is also reduced, making it possible to provide the hat with a high degree of freedom in the size and arrangement of the design part. In particular, in the hat of the first embodiment in which the rear covering portion 11b is constituted by a single piece of sewing fabric 14, it is possible to neatly apply the design portion to the outer surface of the crown outer material ₁₁ at the boundary portion between the left side covering portion _11b1 and the left rear covering portion _11b3 (the portion on the line connecting points _C0 and _P4 in FIG. 2), the boundary portion between the right side covering portion _11b2 and the right rear covering portion 11b4 (the portion on the line connecting points _C0 and _P5 in FIG. 2), and the boundary portion between the left rear covering portion _11b3 and the right rear covering portion _11b4 (the portion on the line connecting points _C0 and _P6 in FIG. 2).

The size of the sewing fabric 14 constituting the rear covering part 11b of the crown outer material 11 is not particularly limited as long as it includes the entire sector-shaped portion ( _left rear covering part _11b3 and right rear covering part _11b4 ) surrounded by points _C0 , _P4 , and _P5 in Fig _{. 2} , and includes at least a part of the rear side (left rear covering part _11b3 side) of the sector-shaped portion (left lateral covering part _11b1 ) surrounded by points _C0 , _P2 , and _P4 , and at least a part of the rear side (right rear covering part _11b4 side) of the sector-shaped portion (right lateral covering part _11b2 ) surrounded by points _{C0, P3,} and _P5 . In other words, the size of the sewing fabric 14 is not particularly limited as long as the central angle θ of the sewing fabric 14 is larger than the angle _P4C0P5 (approximately 120°).

However, if the central angle θ of the sewing fabric 14 constituting the rear covering portion 11b is made too small, the area of the sewing fabrics 13a and 13b constituting the front covering portion 11a will inevitably become large. As described later, it is preferable that the sewing fabrics 13a and 13b are made of thick fabric in order to maintain the shape retention of the crown 10. However, if the area of the sewing fabrics 13a and 13b made of such thick fabric becomes large, there is a risk that the sewing fabrics 13a and 13b will not be able to be curved neatly into a spherical shape. In order to solve this problem, if the front covering portion 11a in the crown outer material 11 is divided into three or more pieces of sewing fabric, the stitched portion of the crown outer material 11 will increase accordingly. For this reason, it is preferable that the central angle θ of the sewing fabric 14 is 180° or more. It is more preferable that the central angle θ of the sewing fabric 14 is 200° or more, and even more preferable that it is 220° or more.

On the other hand, if the central angle θ of the sewing fabric 14 constituting the rear covering part 11b is made too large, the area of the sewing fabrics 13a and 13b constituting the front covering part 11a will inevitably be small. This may make it difficult to maintain the shape of the crown 10. In addition, as described below, the sewing fabric 14 is preferably made of a thin fabric, but if the area is made too large, it may be difficult to curve the sewing fabric 14 neatly into a spherical shape even if the sewing fabric 14 is made of a thin fabric. For this reason, the central angle θ of the sewing fabric 14 is preferably 300° or less. It is more preferable that the central angle θ of the sewing fabric 14 is 280° or less, and even more preferable that it is 260° or less. In the hat of the first embodiment, the central angle θ of the sewing fabric 14 is about 240°.

In the first embodiment of the hat, the sewing fabrics 13a and 13b forming the front covering portion 11a of the crown outer fabric 11 are made of a hard fabric (thick fabric) including interlining. Specifically, a fabric (adhesive interlining) has an adhesive (hot melt adhesive) applied to one side (outer surface) of the fabric, and another fabric (skin) is layered on the side (outer surface) of the fabric to which the adhesive has been applied. After this, the adhesive is hardened after a heat compression process, and the resulting fabric is used as the sewing fabrics 13a and 13b. The skin of the sewing fabrics 13a and 13b is usually a woven or knitted fabric made of synthetic or natural fibers, or a combination of these.

It is preferable to use a press machine with a spherically curved press surface for the heat compression process of the sewing fabrics 13a and 13b, and to curve the sewing fabrics 13a and 13b into a spherical shape when performing the heat compression process. This makes it possible to curve the sewing fabrics 13a and 13b into a hard but beautiful spherical shape. As a result, as described below, even if the rear covering portion 11b of the crown outer material 11 is formed from a thin material, it is possible to maintain the shape retention of the crown 10 well.

In contrast, the sewing fabric 14 forming the rear covering portion 11b of the crown outer fabric 11 is made of a soft fabric (thin fabric) that does not include interlining. Specifically, only the parts of the sewing fabrics 13a and 13b that correspond to the outer skin are used as the sewing fabric 14. Therefore, the sewing fabric 14 forming the rear covering portion 11b of the crown outer fabric 11 is usually made thinner and more flexible than the sewing fabrics 13a and 13b that form the front covering portion 11a of the crown outer fabric 11.

In the hat of the first embodiment, the area (area per piece) of the sewing fabric 14 constituting the rear covering portion 11b of the crown outer material 11 is larger than the area per piece of the sewing fabric constituting the portion corresponding to the rear covering portion 11b in a conventional hat. Therefore, in the hat of the first embodiment, it is difficult to curve the sewing fabric 14 into a beautiful spherical shape, but by forming the sewing fabric 14 from a thin fabric, it becomes easier to curve the sewing fabric 14 into a beautiful spherical shape. In addition, the rear covering portion 11b of the crown outer material 11 is made to easily bulge outward when wind enters it, which also makes it possible to enhance the ventilation effect of the crown 10. It is more preferable to use a sewing fabric 14 that has been treated to be wrinkle-resistant.

By the way, for a fabric with a large surface area, such as the sewing fabric 14, the fabric can be placed between a female mold having a concave portion formed in an approximately spherical shape on the inside and a male mold having a convex portion formed in an approximately spherical shape on the outside, and the female mold and male mold are clamped together while blowing steam onto the fabric from steam holes provided in the concave portion of the female mold and the convex portion of the female mold, and the fabric is sandwiched between the concave portion of the female mold and the convex portion of the male mold and pressurized, to give the fabric a beautiful spherical shape. In this specification, this processing is sometimes called "farming processing". In the hat of the first embodiment, the sewing fabric 14 is also subjected to farming processing. Farming processing can be applied not only to the sewing fabric 14 but also to the sewing fabric 11a, etc. In addition, farming processing can be applied to each sewing fabric (joining fabric) that constitutes the crown 10 of the hats of the second to sixth embodiments described below.

As already mentioned, in the hat of the first embodiment, the crown lining 12 is provided on the inner side of the crown outer material 11. The crown lining 12 may be a continuous surface (closed surface) fabric without openings such as ventilation holes, but in the hat of the first embodiment, the crown lining 12 is made of mesh fabric, which has excellent breathability. It is also not sticky and feels good against the skin. In addition to improving breathability and improving the feel against the skin, this crown lining 12 also has the function of supporting the sewing fabric 14, which is made of a thin fabric as described above, from the inner side.

When the crown lining 12 is provided, the crown lining 12 may be disposed on the entire inner surface of the crown outer material 11, but in the hat of the first embodiment, as shown in Figures 3 and 4, the crown lining 12 is disposed only on the inner surface of the rear covering portion 11b of the crown outer material 11. The crown lining 12 is of approximately the same shape (fan shape with a central angle exceeding 180°) as the number (one) of the sewing fabric 14 constituting the rear covering portion 11b of the crown outer material 11.

The crown lining 12 is sewn to the crown outer material 11, and by forming the crown lining 12 in the same number and with the same shape as the crown outer material 11, it becomes possible to overlap the sewn portion of the crown lining 12 to the crown outer material 11 with the sewn portion of the crown outer material 11. In the hat of the first embodiment, the crown lining 12 is sewn to the crown outer material 11 at the sewn portion _α2 and the sewn portion _α3 in Fig. 2. This makes it possible to prevent the number of sewn portions in the crown 10 from increasing.

As shown in Fig. 3, a backing strip 40 is arranged on the inner surface of the crown 10. The backing strip 42 of the backing strip 40 is arranged along the stitching portion _α2 (Fig. 2) and is sewn together with the stitching fabric 13a, the stitching fabric 14, and the crown lining 12. The backing strip 43 is arranged along the stitching portion _α3 (Fig. 2) and is sewn together with the stitching fabric 13b, the stitching fabric 14, and the crown lining 12. The backing strip 41 is arranged along the stitching portion _α1 and is sewn together with the stitching fabric 13a and the stitching fabric 13b. Therefore, the stitching portions _α1 , _α2 , and _α3 are reinforced by the backing strips 41, 42, and 43, respectively.

The lower edge of the crown lining 12 (the portion along the arcs _{P2 ,} P4, P6 _{, P5, P3} in FIG. 2) may or may not be sewn to the lower edge of the crown outer material 11. In the latter case, it is possible to enhance the ventilation effect by making it easier for outside air to enter the gap between the crown outer material 11 and the crown lining 12 from the underside of the crown 10. The crown lining 12 may be bonded to the crown lining over almost the entire outer surface thereof. However, in this case, the above-mentioned ventilation function is sacrificed.

2. Hat of the Second Embodiment Next, the hat of the second embodiment will be described. Fig. 5 is a view of the hat of the second embodiment seen from diagonally above the front. As shown in Fig. 5, the hat of the second embodiment, like the hat of the first embodiment, has a rear covering portion 11b of the crown outer material 11 made of a single piece of sewing fabric 14, and corresponds to a "rear single-piece type hat". In the following, mainly the parts of the hat of the second embodiment that are different from the hat of the first embodiment will be described, and the parts that are the same as the hat of the first embodiment will not be described.

In the hat of the first embodiment, as shown in Fig. 1, the front covering portion 11a of the crown outer material 11 is composed of two pieces of sewing fabric 13a, 13b. In contrast, in the hat of the second embodiment, as shown in Fig. 5, the front covering portion 11a of the crown outer material 11 is composed of one piece of sewing fabric 13. That is, in the hat of the second embodiment, the number of pieces of sewing fabric 13, 14 constituting the crown outer material 11 is one less than that of the hat of the first embodiment, making a total of two pieces. Therefore, the sewing portion α ₁ (Fig. 2) that exists in the hat of the first embodiment can be omitted in the hat of the second embodiment.

Therefore, in the hat of the second embodiment, not only can the labor and cost for sewing the crown outer material _{11 be further reduced, but also the comfort of wearing the hat can be further improved. Also, in the hat of the second embodiment, since there is no stitching portion α1 on the front side of the crown outer material 11, it is possible to easily provide a design portion by embroidery or a patch at the boundary portion between the left front covering portion 11a1 and} the right front covering portion _11a2 . If the sewing fabric 13 has a central angle of about 120°, it can be curved into a beautiful curved shape by the above-mentioned heat compression treatment.

3. Hat of the Third Embodiment Next, the hat of the third embodiment will be described. The hat of the third embodiment corresponds to the above-mentioned "two-panel type hat". Fig. 6 is a view of the hat of the third embodiment seen from diagonally above the front. Fig. 7 is a view of the hat of the third embodiment seen from above. Fig. 8 is a view of the hat of the third embodiment seen from below. Fig. 9 is a perspective view showing the hat of the third embodiment disassembled. Below, mainly the parts of the hat of the third embodiment that are different from the hat of the first embodiment will be described, and the parts similar to those of the hat of the first embodiment will not be described.

In the hat of the first embodiment, the rear covering portion 11b of the crown outer material 11 is composed of one piece of sewing fabric 14 as shown in Fig. 4, but in the hat of the second embodiment, the rear covering portion 11b of the crown outer material 11 is composed of two pieces of sewing fabric 14a, 14b as shown in Fig. 9. As shown in Fig. 7, the sewing fabric 14a is continuous from the left side covering portion _11b1 to the left rear covering portion _11b3 of the crown outer material 11, and the sewing fabric 14b is continuous from the right side covering portion _11b2 to the right rear covering portion _11b4 of the crown outer material 11.

In the hat of the third embodiment, the sewing fabric 14a and the sewing fabric 14b constituting the rear covering part 11b of the crown outer material 11 must be sewn together at the sewing part _α4 shown in FIG. 7. On the inner side of the sewing part _α4 on the inner side of the crown 10, a backing strip 44 is arranged and sewn together as shown in FIG. 8. The hat of the third embodiment has one more sewing part than the hat of the first embodiment, since sewing must be performed at this sewing part _α4 . However, there is still no need to sew the boundary part between the left side covering part _11b1 and the left rear covering part _11b3 , or the boundary part between the right side covering part _11b2 and the right rear covering part _11b4 in the rear covering part 11b of the crown outer material 11. Therefore, the hat of the third embodiment can also significantly reduce the effort required for sewing the crown outer material 11, as well as significantly reduce the discomfort felt when wearing the hat. Moreover, a design can be suitably applied in the form of embroidery or patches over a wide area of the rear covering portion 11b of the crown outer material 11.

When the rear covering portion 11b of the crown outer material 11 is composed of two sewing fabrics 14a, 14b as in the hat of the third embodiment, the shape and dimensions of the combined portion of the two sewing fabrics 14a, 14b are the same as those of the sewing fabric 14 (Fig. 2) in the hat of the first embodiment. That is, the sum _θ1 + _θ2 of the central angle θ1 (Fig _. 7) of the sewing fabric 14a and the central angle _θ2 (Fig. 7) of the sewing fabric 14b is set to be approximately the same as the central angle θ (Fig. 2) of the sewing fabric 14. The central angle _θ1 of the sewing fabric 14a and the central angle _θ2 of the sewing fabric 14b may be set to different angles, but are usually set to the same value. In other words, the sewing fabric 14a and the sewing fabric 14b are usually set to be symmetrical.

4. Hat of the Fourth Embodiment Next, the hat of the fourth embodiment will be described. Fig. 10 is a view of the hat of the fourth embodiment seen from diagonally above the front. As shown in Fig. 10, the rear covering portion 11b of the crown outer material 11 of the hat of the fourth embodiment is also composed of two sewing fabrics 14a, 14b, similar to the hat of the third embodiment described above, and corresponds to a "two-rear-layer type hat". In the following, mainly the parts of the hat of the fourth embodiment that are different from the hat of the third embodiment will be described, and the parts that are the same as those of the hat of the third embodiment will not be described.

In the hat of the third embodiment, as shown in Fig. 6, the front covering portion 11a of the crown outer material 11 is composed of two pieces of sewing fabric 13a, 13b. In contrast, in the hat of the fourth embodiment, as shown in Fig. 10, the front covering portion 11a of the crown outer material 11 is composed of one piece of sewing fabric 13. That is, in the hat of the fourth embodiment, the number of pieces of sewing fabric 13, 14a, 14b constituting the crown outer material 11 is one less than that of the hat of the third embodiment, making a total of three pieces. Therefore, the sewing portion α ₁ (Fig. 7) that exists in the hat of the third embodiment can be omitted in the hat of the fourth embodiment.

Therefore, in the hat of the fourth embodiment, not only can the labor and cost for sewing the crown outer material _{11 be further reduced, but also the comfort of wearing the hat can be further improved. Also, in the hat of the fourth embodiment, since there is no stitching portion α1 on the front side of the crown outer material 11, it is possible to easily provide a design portion by embroidery or a patch at the boundary portion between the left front covering portion 11a1 and} the right front covering portion _11a2 . If the sewing fabric 13 has a central angle of about 120°, it can be curved into a beautiful curved shape by the above-mentioned heat compression treatment.

5. Hat of the Fifth Embodiment Next, the hat of the fifth embodiment will be described. Fig. 11 is a top view of the hat of the fifth embodiment. In the following, mainly the parts of the hat of the fifth embodiment that are different from the hat of the third embodiment will be described, and the parts similar to those of the hat of the third embodiment will not be described.

In the hat of the third embodiment described above, as shown in FIG. 7, in addition to the crown outer material 11 being sewn (joined) along the front-rear stitching portions α ₁ and α ₄ extending from a point P ₁ at the front of the crown 10 through the center point C ₀ to a point P ₆ at the rear, the crown outer material 11 is also sewn (joined) to a stitching portion α ₂ extending from a point P ₂ at the left front of the crown 10 to the center point C ₀ , and to a stitching portion α ₃ extending from a point P ₃ at the right front of the crown 10 to the center point C ₀ .

In contrast, in the hat of the fifth embodiment, as shown in FIG. 11, the crown outer material 11 is sewn (joined) only along the front-rear stitching portions α ₁ and α ₄ extending from a point P ₁ at the front of the crown 10 through the center point C ₀ to a point P ₆ at the rear, and the crown outer material 11 is not sewn (joined) at the stitching portion α ₂ extending from a point P ₂ at the left front of the crown 10 to the center point C ₀ , and at the stitching portion α ₃ extending from a point P ₃ at the right front of the crown 10 to the center point C ₀ .

That is, in the hat of the fifth embodiment, the portion of the crown outer material 11 that covers the left hemispherical portion of the wearer's head (the left covering portion consisting of the left front covering portion _11a1 , the left side covering portion _11b1 , and the right rear covering portion _11b3 ) and the portion that covers the right hemispherical portion of the wearer's head (the right covering portion consisting of the right front covering portion _11a2 , the right side covering portion _11b2 , and the right rear covering portion _11b4 ) can be formed from a single joining fabric 15a, 15b, respectively. The hat of the fifth embodiment corresponds to the above-mentioned hat divided into two parts, left and right. The sewing fabrics 15a, 15b in the hat of the fifth embodiment are also large in area, but by using thin fabric and subjecting the fabric to firming processing, the sewing fabrics 15a, 15b can be finished into a beautiful spherical shape.

6. Hat of the Sixth Embodiment Finally, the hat of the sixth embodiment will be described. Fig. 12 is a top view of the hat of the sixth embodiment. In the following, the differences between the hat of the sixth embodiment and the hat of the fifth embodiment will be mainly described, and the same parts as those of the hat of the fifth embodiment will not be described.

In the hat of the fifth embodiment described above, the crown outer material 11 is sewn (joined) only along the seam portions _α1 and _α4 in the front-to-back direction as shown in Fig. 11. In contrast, in the hat of the sixth embodiment, the crown outer material 11 is sewn (joined) only along the seam portions _α5 and _α6 in the left-to-right direction perpendicular to the front-to-back direction as shown in Fig. 12. That is, in the hat of the sixth embodiment, the portion of the crown outer material 11 covering the front half of the wearer's head (a front covering portion consisting of approximately the front half of the left lateral covering portion _11b1 , the left front covering portion _11a1 , the right front covering portion _11a2 , and approximately the front half of the right lateral covering portion _11b2 ) and the portion covering the rear half of the wearer's head (a rear covering portion consisting of approximately the rear half of the left lateral covering portion _11b1 , the left rear covering portion _11a3 , the right rear covering portion _11b4 , and approximately the rear half of the right lateral covering portion _11b2 ) can each be formed from a single piece of joining fabric 16a, 16b.

The hat of this sixth embodiment corresponds to the hat of the type described above, divided into front and back. The sewing fabrics 16a and 16b in the hat of the sixth embodiment also have a large surface area, but by using thin fabric and subjecting the fabric to firming processing, the sewing fabrics 16a and 16b can be finished into a beautiful spherical shape.
