Description

A composite soft top structure of a baseball cap

Technical field

The present invention relates to a baseball cap.

Background technique

Baseball caps were originally created to protect athletes from the glare of the sun during baseball games. With the development of the times, its sports attributes have penetrated into every corner of our lives, such as outdoor sports, travel, fitness, daily wear, etc. In our daily life, in addition to providing sun protection and windproof effects, baseball caps also play a more important role in personal wear to modify the overall image.

A baseball cap includes a visor and a cap body (also known as a top). The cap body is composed of front, side and back pages sewn with double-needle tapes; the cap is equipped with eyelets as ventilation holes; the circumference of the cap body There is a circle of sweatband on the inside of the bottom edge, and the lower edge of the sweatband is sewn to the circumferential bottom edge of the hat body; the back part of the hat body can be equipped with or without a back bend and its tail buckle. When the back bend is set, the two back pieces are set correspondingly. There is an arc-shaped notch to form a semicircular back bend; a hat button (also known as a hat bead) can be installed or not at the center of the top of the hat body. Among them, there are two types: flat-brimmed hats and curved-brimmed hats according to the different visors; the eyelets are generally embroidered around the holes (called embroidery holes), and some use metal ring button holes; there are five types according to the number of plates. A six-piece cap or a six-piece hat. A six-piece hat includes two front pages, two side pages, and two back pages for a total of six patterns. The difference between a five-piece hat is that the two front pages are one integral pattern, and there are more The design of the plate; according to the material of the plate, it can be divided into soft top hat and hard top hat. Based on the above differences, the current market mainly includes flat-brim hard-top five-piece and six-piece baseball caps, curved-brim hard-top baseball caps, curved-brim soft-top baseball caps and other hat types.

Among them, the front part of the hard-top baseball cap is made of fabric and Oxford cloth pressed together to make a hard top. This not only affects the comfort of wearing, but also makes the front part of the hat body inconsistent with the side and rear parts, and the hat body matches the head. Bad sex. This affects the natural beauty of wearing it. This has been fully verified by the market in existing hard-top baseball caps: for example, the two front pieces of a curved-brimmed hard-top baseball cap are made of fabric and Oxford cloth laminated to form a hard top, so the wearer's forehead will have a This unnatural fullness effect makes people feel that it is not your own forehead that is full, but the stiff effect of the hat, which creates a sense of distortion; another example is a flat-brimmed hard-top baseball cap, where the front part of the hat is generally The hard top is made of fabric and Oxford cloth. The front part of the hat is stiff and significantly higher than other hat types. When worn, the wearer's head will appear obviously larger, higher and unnatural; even if a flat-brimmed hard top is chosen, Baseball caps, most people choose to wear them backwards or diagonally, are also called hip-hop hats. Therefore, hard-top baseball caps do not conform to the mainstream aesthetics of the public, so the audience is very small.

The panels of the soft-top baseball cap are made of a single layer of soft fabric and are generally washed. The fabric is soft and has good texture and high wearing comfort; and the front part of the cap body and the side and rear parts are coordinated as a whole, and the cap body and the head are harmonious. The matching is good, and if the head shape is suitable, wearing it can produce a strong natural beauty and have a better effect on improving the personal image, which makes it the most in line with public aesthetics among all baseball cap styles.

However, existing soft-top baseball caps have a problem with a small consumer base due to the following reasons:

Because the existing cap body designs on the market are all designed based on standard head shapes, but in fact our head shapes have various contours, and the existing cap bodies cannot meet the diverse needs of the market. In order to verify this phenomenon, we conducted a survey in a prosperous commercial area. The subjects were young people between the ages of 18 and 24. We used mobile APP software for the survey. Each mobile phone was limited to filling out one report. A total of 1,600 pieces of survey data were collected. According to statistics, 23.45% of people are suitable for wearing baseball caps and like to buy them; 50.35% of people will not buy them because they do not look good. The above data shows that the caps on the market cannot satisfy more consumers.

After our research, we found that the reason why it doesn’t look good is that due to the softness of the hat body, the fit between the hat body and the head shape is very high, so the requirements for the head shape are also very high. If the head shape is full or the hair volume is sufficient, the wearing effect will be full, and the personal image will be improved far more than other hat styles; because there are obvious racial differences in the skulls of different races, based on the heads of yellow people Characteristics of this type, the main problem is that the top of the skull is low, the sides of the head are prone to shrinking, and the back of the head is prone to flattening. When this group of consumers wears it, it is easy for their heads to fail to fully support the cap body. For these consumers, if their hair volume or hairstyle is not enough to support the cap body, wearing defects will occur, which are specifically manifested as the following phenomenon: Phenomenon 1 ,Front page collapse: If the part from the forehead to the top of the head cannot support the hat body, the front page (part A and other parts as shown in Figure 1) will collapse a lot. The rounded hat body design itself will appear when wearing it. Various corners and dents caused by collapse; Phenomenon 2, the top of the hat becomes pointed: If the side panels cannot be propped up, causing the top of the hat body (part B as shown in Figure 2) to shrink inward, causing the top of the hat to become pointed. It will also produce a sense of déjà vu when the face is big and the head is small; Phenomenon 3, the back page collapses: For people with a flat or not full back of the head, the back page of the hat (part C as shown in Figure 3) will collapse when wearing it. Severe wrinkles appear around the back curve, which affects the look and feel of the sides and back when worn; Phenomenon 4, protruding back curve: If the head circumference does not match, the upper part of the hat will bend back (part D as shown in Figure 4) Unnatural arching; Phenomenon 5, wrinkles on the hat body: Due to the lack of support from the head or hair, the hat body will have many wrinkles or uneven spots (part E shown in Figure 5), which will place the wearer’s head on the head. All flaws are exposed. The above-mentioned wearing defects make the fitness of baseball caps low, resulting in a strange situation of "hat selection" in the eyes of the public, making A large number of potential consumers can only stay away, thereby reducing the consumer group of baseball caps.

In addition, by collecting and modeling the head shape data, and then comparing and analyzing the body model of the curved brim soft-top baseball cap with the three-dimensional model of the head, the following conclusions can be drawn: 1. The part between the forehead and the top of the skull, From the turning point of adduction of the side of the head to the area between the top of the skull and the back of the head, the probability of gaps appearing between the three places above the head and the inside of the cap body is relatively high; 2. The distance between the gaps is about 0 to 20 mm. between; 3. The above three places are generally the places with the largest gaps.

To sum up, existing soft-top baseball caps have the disadvantages of poor wearing effect, which restricts their market prospects to a certain extent, and therefore it is necessary to improve them. However, no public reports of relevant research improvements have been found.

Contents of the invention

In order to solve the above disadvantages, the technical problem to be solved by the present invention is to provide a composite soft top structure of a baseball cap, which can not only effectively eliminate the wearing defects of the soft top hat, but also keep the soft top hat soft and comfortable, and the front part of the hat body and the The advantages of overall coordination of the sides and rear, and good matching between the hat body and the head.

Detailed ways

Referring to Figures 6-15, a specific structure of the present invention is reflected. The composite soft top baseball cap described in the example is a six-piece curved brim baseball cap, including a curved brim visor 5 and a hat body. The hat body consists of two front pages 1, two side pages 2 and two back pages 3, a total of six pieces. Each panel is composed of double-needle belt stitching. Each plate is provided with eyelets 4. A circle of sweatband 9 is provided on the inside of the circumferential bottom edge of the hat body, and the lower edge of the sweatband 9 is sewn to the circumferential bottom edge of the hat body. A hat button 7 is provided at the top center of the hat body.

Each front page 1 includes an outer layer of front page fabric 101, a middle layer of front page fiber web 102, and an inner layer of front page lining cloth 103: each side page 2 includes an outer layer of side page fabric 201, a middle layer of side pages. The fiber web 202 and the inner side page lining cloth 204 are also provided with a shaping layer 203 between the side page fiber web 202 and the side page lining cloth 204; each back page 3 includes an outer back page cloth 301, a back page cloth 301 of the middle layer, and a shaping layer 203. The fiber web 302 and the inner back lining cloth 303.

The surface fabric and interlining fabric are sewn with double needle belt:

Among them, the double-needle tape stitching between the two front pages 1 adopts a double-layer structure, the double-needle tape stitching between the front page 1 and the side page 2 adopts a single-layer structure; the double-needle tape stitching between the two back pages 3 It adopts a double-layer structure, and the double-needle belt stitching between the back page 3 and the side page 2 adopts a single-layer structure.

Below, the double-layer structure is explained by taking the double-needle belt stitching of two front pages 1 as an example: Refer to Figure 14, the double-layer structure means: the adjacent sides of the two front page cloths 101 are passed through the first double-needle belt 12 The surface fabric layer is formed by sewing, and the adjacent sides of the two front page interlining fabrics 103 are sewn through the second double needle belt 10 to form the interlining layer. There is no sewing between the first double needle belt 12 and the second double needle belt 10. Within the range, the surface fabric layer and the lining fabric layer are two separate layers. The processing of the two following pages 3 is the same as the previous page and will not be repeated.

As shown in Figure 14, the adjacent sides of the two front-page cloths 101 are first sewn at the position of the suture line 105, the two suture edges 104 are turned over and flattened, and then sutured through the first double needle belt 12. The processing of the interlining is the same as this; the processing of back page 3 and side page 2 is also the same and will not be described again. This structure can effectively improve the two-way stress conduction capacity between the double-needle belt and the surface fabric and lining fabric. Through the frame structure composed of all double-needle belts, the uniformity of the overall force on the hat body is improved.

Figure 14 also shows that the side of the front page fiber web 102 is close to and parallel to the outer edge of the double needle belt, and the front page fiber web 102 does not enter the sewing range of the double needle belt. The fiber webs on the back pages and side pages are processed in the same way and will not be described again.

Taking double-needle stitching of side page 2 and back page 3 as an example to illustrate the single-layer structure: see Figure 15, the single-layer structure refers to: adjacent side page fabric 201, back page fabric 301, side page lining fabric 204 and the back page interlining 303 are all sewn together through the third double needle belt 11 to form a single layer of the whole. The connection processing of front page 1 and side page 2 is also the same and will not be described again. It can be seen that the connection strength of the single-layer structure is greater than that of the double-layer structure. Through the differentiated design of single and double layers, the matching of the hat body and the head can be ensured on the basis of ensuring the support strength of the hat body, thereby making the wearing effect natural.

At the same time, because the center positions of the front and back of baseball caps often require embroidery to produce logos and other iconic content, this position is exactly at the seam between the two back pages and the two front pages. The double-layer structure also has the advantage of facilitating surface fabric embroidery. On the front page 1 and the back page 2, After the fabric layer is made, the embroidery process can be completed first and then the panels and the hat body are combined to prevent the embroidery from penetrating the fiber mesh and interlining, affecting the stress conduction of the hat body, causing undesirable deformation and affecting the appearance.

The fiber web is sewn to the fabric through eyelets: the previous page 1 is taken as an example. As shown in Figure 9 in the example, the fiber web 102 on the front page is sewn to the front fabric 101 through eyelets 4, that is, in the embroidery process of eyelets 4 around the holes, The two are sewn together. The processing of back page 3 and side page 2 is the same and will not be described again. The difference is that the front page fiber web 102 is only stitched with the front page cloth 101 through eyelets, and other positions of the front page fiber web 102 are not connected to the cap body through stitching; while the side page fiber web 202 is also sewn with the shaping layer 203; set At 6 o'clock in the back bending, the back page fiber web 302 enters the sewing range of the back bending double needle belt 305.

The bottom edge of the fiber mesh does not enter the sewing position of the lower edge of the sweatband: Take the previous page 1 as an example, see Figures 7 and 8 in the example. There is a circle of sweatband 9 on the inside of the circumferential bottom edge of the hat body, and the lower edge of the sweatband 9 is in line with the stitching position. The circumferential bottom edge of the hat body is sewn, and the bottom edge of the fiber web 102 on the front page does not enter the sewing position of the lower edge of the sweatband 9 . The processing of back page 3 and side page 2 is the same and will not be described again.

In the example, the front page fiber web 102 is a single layer fiber web. This makes the front page 1 form a weak support structure, which can form a local subtle collapse when worn, enhancing the natural feeling of wearing. In other embodiments, the front page fiber web can also be composed of a double-layer fiber web sewn around the periphery. to enhance the supporting structure of the front page as needed.

Referring to Figures 7, 10, and 11, in the side page 2 of the example, the periphery of the shaping layer 203 is sewn to the side page fiber web 202, and the shaping layer 203 and the side page fiber web 202 are also sewn to the surface fabric 21 through the eyelets 4; The shaping layer 203 does not enter the sewing range of the third double-needle belt 11; the sides of the shaping layer 203 are close to and parallel to the outer edge of the third double-needle belt 11, and the bottom edge of the shaping layer 203 and the upper edge of the sweatband 9 The edges are flush, and the shaping layer 203 and the sweatband 9 do not overlap.

In the example, the back page 3 is provided with a back bend 6 and its tail buckle 8, and the two back pieces 3 are correspondingly provided with arc-shaped notches 304 to form a semicircular back bend 6. The back-bending part is provided with a back-bending double-needle belt 305, and the back-page fiber web 302 enters the sewing range of the back-bending double needle belt 305. It is used to enhance the shape maintenance of the back-bent opening and make the curve of the back-bending part more perfect. At the same time, this structure is conducive to the structural stability of the entire back page: the back-bent double needle belt 305 is connected to the back-page fiber mesh 302, which will make the edge of the back-bending hole harder, thereby better ensuring that the back-bending 6 is not worn when worn. Distortion will occur; secondly, it can provide supporting stress for the back page material 301 in the area near the back bend 6, with the support stress provided by the back bend double needle belt 305 and the second double needle belt 11 connecting the side page 2 and the back page 3 , and the strength of the combination of the back page fiber mesh 302 and the back page cloth 31 enables the back bend part to maintain its own shape when it is not needed to be worn, and the back bend hole can also maintain a perfect state, thereby achieving Self-supporting.

In other embodiments, the back bend may not be provided, and the structure of the subsequent pages is the same as that of the previous pages, which will not be described again.

In the above technical solution: the front page fiber web 102 is only sewn to the front page cloth 101 through the eyelets 4, and other positions of the front page fiber web 102 are not sewn to the cap body. The front page fiber web 102 is used to improve the supporting capacity of the front page cloth 101 and spread the extrusion force of the front page lining 103 to the front page cloth 101 evenly and widely; this force component effectively avoids The wearing defect of the front page collapses, the front page shows a rounded and full effect. At the same time, the structure can maintain softness, and the structures of the front and side pages of the cap body are similar and coordinated, effectively improving the matching between the cap body and the head. Compared with the laminated hard top made of cloth and Oxford cloth, the hard top is effectively avoided and the wearing effect is more natural.

When wearing, the side leaf 2 is squeezed and stretched by the head, and part of the stress is transmitted to the third double needle belt 11 connecting the side leaf 2 and the front page 1, causing the double needle belt to expand and link the front page plate; front page 1 The fiber mesh structure layer itself can spread the force to the surface cloth more evenly. Even if our head only contacts the front page a little, the force at the contact point can be spread to a larger area of the front page. When not being worn, the front page of the hat body is sufficient to support its own weight through its structural form without major collapse.

In addition to being used to fix the shaping layer 203, the side page fiber web 202 can also evenly distribute the extrusion force of the shaping layer 203 to the surface cloth, so that the surface cloth will not change abruptly when it is squeezed. More natural. The side page structure mainly provides automatic shaping function. Because it must be in direct contact with the head, it will be subject to the extrusion force from the head. This extrusion force will cause the double needle belt connecting the side page to the front page, and The double-needle straps connecting the side pages and the back pages have outward expansion stress, which directly enhances the support effect of the entire cap body. The double-needle tape stitching on the side pages is a single-layer structure with multiple layers of fabrics stacked. Compared with the single-layer fabric of the traditional hat body, its structural strength is higher; and because the double-needle tape is connected to the lining, the lining is the first to contact the head , so the stress on the lining can be directly transmitted to the double-needle belt to provide stress for it.

The shaping layer 203 uses a silk floss sheet of a certain thickness, which can provide the wearer with elastic shaping functions: such as the shape of the head that is retracted on both sides of the head, and the gap between the two sides of the head and the inside of the hat body. Larger, the shaping layer receives less extrusion force, so it is in a fluffy state, and its thickness can be used to fill the gaps and support the shape of the fabric; if both sides of the head are normal, the gap spacing is small and the shaping layer The layers will be compacted and thinned by greater extrusion force; and the force will be evenly transmitted to the fabric through the fiber mesh, allowing the fabric to achieve a round and full shaping effect.

In order to verify the structural performance of the cap body, we conducted the following comparative test experiments:

1. Test objects:

Experimental group: 10 of the six-piece curved brim composite soft-top hats produced in the above embodiment were randomly selected;

Control group: 10 six-piece soft-top hats with curved brim made by existing technology, randomly selected;

The experimental group and the control group used the same material fabrics, double-needle belts, and sweatbands; adopted the same pattern; and used the same ironing method.

2. Test method: Handle and place with care, place the hats of the experimental group and the control group flat on the same table, and cover the two groups of hats with transparent plastic covers to prevent moisture and air fluctuations from affecting them. Time and observe and record the deformation of the hat.

3.Test results:

3.1 During the process of laying it flat, the hats in the experimental group remained in their original shape without any deformation; after the hats in the control group were placed on the table, various deformations immediately appeared on the hats, see the table below:

3.2 After 72 hours, the deformation of the two sets of hats is shown in the table below:

3.3 After 168 hours, the deformation of the two sets of hats is shown in the table below:

4. Test conclusion: The self-supporting ability of the hats in the experimental group is significantly better than that in the control group.
