Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of a collar core of school uniform.

[0002]

2. Description of the Related Art Conventionally, a collar of a school uniform is often provided with a collar core, and it is made difficult for the collar core to be wrinkled or deformed. As a conventional collar core,
A plate made of relatively hard cotton used as an interlining for clothes
A body or a plate-shaped body made of synthetic resin is used. Then, the collar core thus formed is covered with the cloth of the collar portion of the school uniform from both inside and outside so that a curved collar can be formed by the collar core and the cloth (see FIG. 4). ).
However, since the collar core is composed of a plate-like body that extends straight in the left-right direction, even if you try to form the collar into a curved shape that fits exactly around the neck, it will return to the original straight plate shape. Due to the elastic force of the neck core, it deforms into a large curved shape with a diameter larger than the neck, and as a result, it is difficult for the collar to follow the neck when wearing school clothes and the collar fits the neck. It's hard to do. Moreover, when wearing school uniforms, the opening of the collar is pushed open and the collar is deformed into a large curved shape, so
Along with the elastic force of the collar core described above, there is a problem in that it is deformed into a large-diameter curved shape each time it is used. Also, if the collar core is formed from a plate made of synthetic resin, it is difficult for the collar to wrinkle or lose its shape, but it is inferior in terms of suppleness and the collar does not move when wearing school uniform. It is difficult to flex and gives a tight feeling to the neck.

[0003]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above circumstances, and can be formed on a curved collar having a size that easily fits around the neck, and moreover, it can be bent along the neck. The first purpose is to provide a soft collar core that can be maintained in a shape.

According to the present invention, a curved collar having a size that easily fits around the neck can be formed and can be maintained in a curved shape that fits around the neck.
The second purpose is to provide a soft collar that has sufficient flexibility and bends according to the movement of the neck when wearing school clothes and does not give a feeling of pressure to the neck.

It shall be heated at the temperature. By doing so, when the inner layer 3 is heated at a temperature higher than the temperature at which heat shrinkage occurs, the inner layer 3 shrinks more than the outer layer 2, and as a result, the entire left end side to the right end side is bent toward the inner layer 3 side. It can be formed in a curved shape. As a result, unlike the case where the conventional straight collar core is arranged and the collar is formed in a curved shape along the neck, it does not become large in diameter due to the elastic force to return to the straight shape. The curved shape along the neck can be maintained.
Further, even when the collar opening K4 is widened to widen the diameter of the collar K1 when it is worn, the elastic force of the collar core 1 allows the collar K to return to the original curved shape with a small diameter. Therefore, the collar can be held in a curved shape that always follows the neck. On the other hand, in manufacturing, the outer layer 2 and the inner layer 3 need only be heat-welded, and can naturally be formed into a curved shape without a separate step of forming into a curved shape.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be specifically described below with reference to the drawings. 1 (A) is a front view of a soft collar core according to an embodiment of the present invention, FIG. 1 (B) is a plan view thereof, and FIG. 2 is an end face taken along line II-II of FIG. 1 (A). It is a figure.

The soft collar core 1 of the present embodiment comprises a collar core body 1a, an engaging member 4a attached to the collar core body 1a,
4b and insignia holes 6a ... 6b formed in the collar core body 1a
It has and.

The core body 1a is composed of two laminated layers, an outer layer 2 and an inner layer 3. Further, the collar core main body 1a has a curved shape which is bent toward the inner layer 3 side in a normal state, and has a total thickness of about 2.0 mm, and has a left-right length in a straight extended state. Is about 440 mm, and the vertical width is about 38 mm.

The outer layer 2 and the inner layer 3 are made of materials having different heat shrinkage rates, and the inner layer 3 is made of a material having a heat shrinkage rate higher than that of the material forming the outer layer 2. In this embodiment, the outer layer 2 is made of synthetic leather and the inner layer 3 is made of polyester. Specifically, the outer layer 2 is 0
% Or a synthetic leather having an extremely low heat shrinkage rate close to this is used, and this synthetic leather has a surface layer corresponding to the silver surface layer of natural leather formed of a dense sponge layer of polyurethane,
A base layer corresponding to a net-like layer of natural leather is formed by using a fiber binder and a polymer substance such as polyurethane elastomer as a binder, and has flexibility (flexibility),
Further, it has characteristics such as excellent breathability and moisture permeability.
The thickness of the outer layer 2 is about 1.6 mm. The inner layer 3 has a repulsive force and has a thickness of 0.4 m formed by weaving a thread-like polyester thread having a heat shrinkage rate of 1.5% in the longitudinal and transverse directions.
It is composed of a sheet-like woven fabric having a size of about m, and has sufficient air permeability and breathability. When the fabric is formed as in this embodiment, it is not limited to the one in which one polyester yarn formed into a thread shape is woven, and for example, a thread-shaped polyester thread is spirally wound around a thread-shaped polyester thread. The covering thread may be formed by weaving a covering thread in the lengthwise and crosswise directions, and may be appropriately changed.

The inner surface of the outer layer 2 and the inner layer 3 are
The outer surface of the core body 1a is heat-welded to form a single curved core body 1a in which the inner layer 3 is laminated inside the outer layer 2. This heat welding is performed, for example, by arranging a heat-meltable resin material that can be melted at a temperature lower than the melting temperature of the outer layer 2 and the inner layer 3 between the inner surface of the outer layer 2 and the outer surface of the inner layer 3 and heating from both inside and outside. It can be carried out by pressing, and by pressing with a heated mold, the heat-melted resin material is melted by the heat of the mold, and the inner surface of the outer layer 2 and the outer surface of the inner layer 3 are melted. Weld through.
Further, during this welding, the outer layer 2 and the inner layer 3 are heated and are affected by heat. At that time, since the inner layer 3 has a higher heat shrinkage rate than the outer layer 2, the inner layer 3 welded to the outer layer 2 shrinks more than the outer layer 2, and as a result, the whole from the left end side to the right end side is bent toward the inner layer 3 side. It becomes curved. In the present embodiment, the outer layer 2 having a heat shrinkage of 0% or close thereto and the inner layer 3 having a heat shrinkage of 1.5% are pressed by a mold heated to about 140 ° C. to 150 ° C. It is formed in a curved shape with a radius of about 200 mm. The size of the curved shape of the collar core body 1a is not particularly limited, but the radius of curvature is 1
If it is less than 40 mm, it becomes smaller than the neck of the person and becomes cramped when worn, while the radius of curvature is 50.
When it is 0 mm or more, the curved shape becomes too large as compared with the neck circumference, and it becomes difficult to fit the neck, and the effect of keeping the curved shape decreases. Therefore, it is preferable to set the radius of curvature from about 140 mm to about 500 mm. Also, the radius of curvature is 180 mm
In the following cases, it becomes difficult to sew fabrics K2 and K3 of a collar K1 described below that covers the collar core body 1a. On the other hand, when the radius of curvature is 350 mm or less, it is easier to fit the neck. Therefore, it is preferable to set the radius of curvature from about 180 mm to about 350 mm.
More preferable. In addition, the deflection due to the difference in the thermal contraction rate is
Actually, it also occurs in the upper and lower width directions, but since the upper and lower width dimensions are small, it is only slightly bent.

In the present embodiment, the outer layer 2 and the inner layer 3 are heat-welded to each other by partially welding the inner surface of the outer layer 2 and the outer surface of the inner layer 3 by using a hot-melt resin sheet formed in a stitch shape. Thus, the breathable moisture permeability of the outer layer 2 is not impaired, but a seamless film may be used to cover the entire inner surface of the outer layer 2 and the outer surface of the inner layer 3. Further, the method of heat welding is not limited to a form using a heat-melting resin sheet having separate stitches or a heat-melting resin film having no stitches, for example, from a method in which the heat-melting resin is preliminarily included in the inner layer 3. The outer layer 2 may also be configured.
The inner layer 3 and the inner layer 3 can be partially welded to each other so that the breathability of the outer layer 2 is not impaired. Further, by heat welding, a heat-melting resin sheet having separate stitches or a heat-melting resin film having no stitches is adhered to the inner surface of the outer layer 2 or the outer surface of the inner layer 3 in advance to form the outer layer 2 and the inner layer 3. It is also possible to stack and emboss. On the other hand, the embossing can be performed by an upper die and a lower die having a planar embossing surface, but in the present embodiment, as shown in FIG. 3, the embossing surface 51a having a curved convex surface is used. A lower mold 51 having an upper surface,
By using the upper die 52 having a lower surface having a curved die-pressing surface 52b, the inner layer 3 is arranged on the die-pressing surface 51a side of the lower die 51, and the die-pressing surface 51a of the lower die 51 and the upper die 52 You may make it press with the embossing surface 52b. By embossing with such a curved uneven surface, it is possible to bend the outer layer 2 and the inner layer 3 due to the difference in the heat shrinkage rate without hindering the bending of the outer layer 2 and the inner layer 3.

The collar core body 1a thus heat-welded and formed into a curved shape has the outer layer 2 made of synthetic leather, so that it has sufficient flexibility as a whole and exerts a force. If added, it can be easily deformed and bent. On the other hand, the supple outer layer 2 can be reinforced in terms of strength by the inner layer 3 formed of a woven fabric of polyester yarn having a repulsive force, and can be made as a whole as a whole. Therefore, it has a sufficient restoring property as a whole, can be restored to the original shape by removing the force after deforming by applying a force, and it is possible to maintain the curved shape and also the vertical strength. In addition, it can be made so-called elastic, and it is possible to prevent the vertical settling and keep the shape.
In addition, since the inner layer 3 is made of a woven fabric, the breathability of the outer layer 2 is not impaired, and the breathability of the outer layer 2 as a whole is obtained. The overall hardness can be adjusted by changing the thickness ratio between the outer layer 2 and the inner layer 3.
When the synthetic leather is thinned and the woven fabric of the inner layer 3 is thickened, the suppleness as a whole is decreased, while the restoring force can be strengthened.

The engaging members 4a, 4b of the collar core 1 are made of school clothes K
It is for closing the opening K4 (see FIG. 4) of the collar K1 and is composed of a hook 4a and an engaging portion 4b formed so that the hook 4a can be engaged and disengageably engaged. The hook 4a is attached to the right end of the collar core body 1a, and the engaging portion 4b is attached to the left end of the collar core body 1a.
When the hook 4a is engaged with the engaging portion 4b, the collar core 1 has an annular shape.

The insignia holes 6a ... 6b of the collar core 1 are in the school uniform K
This is for inserting the shaft of the insignia when attaching the insignia to the collar K1 and is composed of two types of holes, circular small holes 6a and 6a and long groove-shaped elongated holes 6b and 6b. The small hole 6a and the long hole 6b are formed on both left and right sides of the collar core body 1a so as to penetrate from the outer layer 2 to the inner layer 3. In this way, by providing the insignia holes 6a ... 6b in advance, when attaching the insignia to the collar K1 of the school uniform K, the inner cloth K2 and the outer cloth K3 ( (See Fig. 4)
Thereby, the hole for attaching the insignia to the collar K1 can be made to penetrate from the inner cloth K2 of the collar K1 to the outer cloth K3 through the small hole 6a or the long hole 6b, and the mounting operation can be facilitated. Further, by providing the long holes 6b and 6b in addition to the small hole 6a, the position of attaching the insignia to the collar K1 of the student clothes K can be adjusted.

As shown in FIGS. 4 and 5, the soft collar core 1 of the present invention constructed as described above has the inner layer 3 of the collar core 1 on the front side (the inner surface side of the student uniform) and the student uniform K. The inner cloth K2 forming the inner surface of the collar K1 and the outer cloth K3 forming the outer surface are arranged and sewn. At this time, the inner cloth K2 is shorter in length than the outer cloth K3.
Inner cloth K2 and outer cloth K3 after sewing the outer cloth K3
The shape formed by and is made to substantially match the curved shape of the collar core body 1a. Therefore, the collar core body 1a after being sewn is hardly stretched or compressed by sewing the inner cloth K2 or the outer cloth K3, and can maintain the curved shape when the outer layer 2 and the inner layer 3 are heat-sealed. . Further, at the time of sewing, since the outer layer 2 is made of synthetic leather and the inner layer 3 is made of a sheet-like woven fabric, the sewing thread can be easily passed through the inner cloth K2, the outer cloth K3 and the collar core 1. Furthermore, since the collar core 1 is curved with a radius of curvature of about 200 mm, it can be easily sewn by hand or a sewing machine. By this sewing, the entire collar core 1 excluding the hooks 4a and the engaging pieces 4b is covered with the inner cloth K2 and the outer cloth K3, and the collar K1 of the school uniform K is covered.
Forming the core of the.

By forming the collar K1 of the school uniform K in this manner, the collar core 1 has a pre-curved shape, so that a conventional straight collar core is arranged around the neck. It is possible to maintain the curved shape along the neck circumference without receiving the elastic force that tends to return to the straight shape as in the case of forming the curved shape along the neck so as not to increase the diameter. Further, even when the collar opening K4 is widened to increase the diameter of the collar K1 when it is worn, the elastic force of the collar core 1 can restore the curved shape with a small diameter along the original neck circumference. Therefore, the collar can be held in a curved shape that always follows the neck. Moreover, since it has sufficient flexibility, the collar flexes in accordance with the movement of the neck, giving the person wearing it a soft feeling and making it comfortable. Further, since the entire collar core 1 has a breathable and breathable property, it is possible to prevent the collar core 1 from being peeled by sweat when worn.

[0023] In the present embodiment, the inner layer 3, although those having a vent moisture permeability constitutes a woven textile of polyester yarn, not limited to this embodiment, nonwoven fabric, knitted fabric or the like As described above, it may be in a form having a breathable and breathable property or a form such as a film having no breathable and breathable property. Further, the material forming the outer layer 2 and the inner layer 3 is the inner layer 3
May be made of a material having a heat shrinkage higher than that of the outer layer 2, and is not particularly limited. For example, the outer layer 2 is a non-woven fabric formed of synthetic leather, polyester, nylon, or the like,
It is composed of one selected from a woven fabric, a knitted fabric, a film, etc., and is selected from a synthetic leather, a non-woven fabric, a woven fabric, a knitted fabric, a film, etc. in which the inner layer 3 is formed to have a heat shrinkage ratio higher than that of the outer layer 2. You may comprise from one. However, it is preferable that at least one of the outer layer 2 and the inner layer 3 is made of synthetic leather, because the whole can be made flexible. To exemplify the case where at least one of the outer layer 2 or the inner layer 3 is made of synthetic leather, the outer layer 2 is made of synthetic leather, and the inner layer 3 is made of synthetic leather having a higher heat shrinkage rate than the synthetic leather of the outer layer 2, and the outer layer. Nonwoven fabric made of polyester, nylon, etc., which has a higher heat shrinkage rate than the synthetic leather of 2.
A woven fabric, a knitted fabric, a film, or a synthetic leather in which the inner layer 3 is made of synthetic leather and the outer layer 2 has a lower heat shrinkage rate than the synthetic leather of the inner layer 3, and the heat shrinkage rate thereof is lower than that of the inner layer 3. Non-woven fabrics, woven fabrics, knitted fabrics, and films formed from polyester, nylon, and the like. When one layer of the outer layer 2 or the inner layer 3 is made of synthetic leather, it is preferable that the other layer is made of a non-woven fabric, a woven fabric, a knitted fabric, or a film in order to obtain a supple synthetic leather in terms of strength. Can be reinforced,
It is more preferable in that it has a sufficient restoring property as a whole and can return to its original shape even if it is deformed by applying a force.

In this embodiment, the outer layer 2 and the inner layer 3 are two layers, but at least two materials having different heat shrinkages are used. It is sufficient that the material is made of a material that does not undergo heat shrinkage, for example, in between, or at the outermost side to form three layers, or has a higher heat shrinkage ratio than the outer layer 2 and more than the inner layer 3. A material having a low heat shrinkage rate may be composed of three or more layers, such as by disposing it between the outer layer 2 and the inner layer 3 to form three layers, which can be appropriately changed. When an intermediate layer is provided between the outer layer 2 and the inner layer 3 and these three layers are bonded together, the outer layer 2 and the inner layer 3 are not directly heat-welded, but, for example, between the outer layer 2 and the intermediate layer. , And by arranging a hot-melt resin material between the intermediate layer and the inner layer 3 and pressing them with the above-mentioned heated mold, the outer layer 2 and the inner layer 3 can be heat-bonded via the intermediate layer.

Furthermore, the soft collar core 1 of the present invention may be subjected to antibacterial or deodorant treatment, or sweat absorption processing. For example, an inner layer 3 using an antibacterial, deodorant, or sweat absorbing material may be used, or an antibacterial sheet material may be attached to the inner surface of the inner layer 3.
It can be changed appropriately.

[0026]

As described above, according to the first or second invention of the present application, when the inner layer 3 is heated at a temperature higher than the temperature at which heat shrinkage occurs, the inner layer 3 shrinks more than the outer layer 2. It can be bent to the side and formed into a curved shape. As a result, unlike the case where the conventional straight collar core is arranged and the collar is formed in a curved shape along the neck, it does not become large in diameter due to the elastic force to return to the straight shape. The curved shape along the neck can be maintained. Further, even when the collar opening K4 is widened to increase the diameter of the collar K1 when it is worn, the elastic force of the collar core 1 can restore the curved shape with a small diameter along the original neck circumference. Therefore, the collar can be kept in a curved shape that always follows the neck, and can be fitted around the neck at all times when wearing school uniform. On the other hand, in manufacturing, the outer layer 2 and the inner layer 3 need only be heat-welded, and can naturally be formed into a curved shape without a separate step of forming into a curved shape. In addition, it has sufficient flexibility
