Description

The present invention relates to an eave for a hat with an eave, which is made of a flexible material as a core, yet can easily maintain its shape, and can maintain the same shape (symmetrical) even after being reversely bent.

Conventionally, the eaves of hats with eaves had a steel core in order to maintain their shape.
Furthermore, in the case of flexible eaves, no technology had been established to maintain their shape.

Most of the eaves of conventional hats with eaves had a steel core, which made them difficult to store, the edges frayed, and because they were hard, they were sometimes dangerous.
Items with flexible eaves are easy and safe to store, but they are difficult to maintain their shape.
Both had contradictory drawbacks.

The present invention is an attempt to solve the problems associated with the conventional eaves of hats, and by changing the shape and structure of the members, the eaves made of a flexible material are made difficult to deform. It provides functional beauty and improves usability.

Means to solve problems

The present invention involves dividing a material such as a flexible non-woven fabric that is resistant to bending and impact, which is a member of the eaves, into flat parts, and covering the whole surface from the front and back, with the same shape and area. (processing allowance for the surrounding area is required), stitch around the periphery, put a seam in the part that will become the ridge line, bend it along three vertical lines (center and both sides), and then By sewing together the part that will become the part joining line), it forms a part of a ridge line and pyramid (by angling the seams on both sides forward and inward, it becomes part of a pyramid) instead of a conventional curved surface. It uses the principle that it can be done.

Effect of the invention

By bending at the seam (and ridgeline), it forms a part of the ridgeline and pyramid, and even if it is reversed (reversely bent), the same shape can be formed.
By forming ridge lines on a flat surface, stress is generated in response to external forces, making it easier to maintain the shape.
Even if it is reversed (reversely bent), it will remain the same shape (original symmetrical shape).

Best mode for carrying out the invention

Place the member that will become the base of the eaves (developed shape of the eaves) on a flat surface, divide it into two by a straight line that crosses the center vertically, and then divide the two pieces on both sides by any equidistant longitudinal straight line on both sides. Divide each into two.
At this time, the inner (front) angle of the intersection of a horizontal line drawn at right angles from the origin of the center longitudinal line and the equidistant longitudinal lines on both sides is less than a right angle, and the longitudinal lines on both sides do not intersect with the center longitudinal line on the member.

Sandwich the fabric between the front and back sides with the same shape and area (additional processing allowance for the surrounding area will be required later), perform sewing around the periphery, and create seams on three (longitudinal) straight lines.

Three (longitudinal) straight lines are bent to form a ridge line and (a part of the pyramid), and this shape is sewn to the head member joining line.

By using this principle and structure for the eaves of hats with eaves, we have achieved heat resistance, cold protection, sweat absorption, storage, safety, durability, environmental protection, artistry, functionality, novelty, and practicality.・It has applicability, innovativeness, and ability to develop new types, and can be used in a wide variety of areas, including disaster prevention, leisure, travel, entertainment, play, carpentry, agricultural work, light work, learning, fashion, civil engineering work, steel work, and construction work. It is.

Claims (1)

Between two pieces of cloth (or similar material), there is a central vertical straight line that divides the left and right equally into two, and a vertical straight line that further divides both sides into two (at the same distance from the central vertical straight line on the left and right, from the rear outside) Place the divided nonwoven fabric (or similar material) in the fixed position before dividing, and place the divided nonwoven fabric (or similar material) on the three dividing lines from the top of the cloth (or similar material). By sewing and folding along the seams, the entire eave forms a ridgeline and at the same time forms part of a pyramid. Even when folded inside out, the eave forms a ridgeline in the same way, and the entire eave forms part of a pyramid. Eaves that can.
