In addition, when the plurality of protrusions are disposed along the inner side of the arc shape, the structure of the inner side of the headband becomes complicated, so that the arc-shaped headband can not be manufactured by a single molding process. After the flat- , A headband is manufactured in such a manner that the headband is bent in the form of a call. In the process of bending the headband in the form of an arc, fatigue is accumulated in the headband, so that the rigidity of the headband is weakened. When the thickness of the headband is thin enough, the headband is easily broken.

Therefore, a technique for solving the above-described problems is required.

On the other hand, the background art described above is technical information acquired by the inventor for the derivation of the present invention or obtained in the derivation process of the present invention, and can not necessarily be a known technology disclosed to the general public before the application of the present invention .

The headband 100 according to an embodiment of the present invention may be a member that functions as a hair accessory to be worn on the head to suppress the flow of hair or to produce various hair styles.

Referring to FIG. 1, a headband 100 according to an embodiment of the present invention includes a frame 110 and a protrusion 120 protruding from an inner surface of the frame 110.

The frame 110 functions as a body of the headband 100 and is bent in an arc shape. The radius of curvature of the frame 110 can be variously determined to correspond to the radius of curvature of the wearer's head. For example, if the main wearers of the headband 100 are children, the radius of curvature of the frame 110 may be determined to correspond to the radius of curvature of the average head of the children. However, the present invention is not limited thereto, and the radius of curvature of the frame 110 can be variously determined according to the type of the main wearer.

The frame 110 may have a sufficiently thin thickness. For example, the frame 110 may have a thickness of 0.5 mm to 10 mm. However, the present invention is not limited thereto, and the thickness of the frame 110 can be variously determined depending on the material, size, shape, width, length, etc. of the frame 110.

The shape of the outer side surface and the inner side surface of the frame 110 is not particularly limited. 1 illustrates a frame 110 having an outer side and an inner side of a rectangular shape. However, the outer and inner sides of the frame 110 may have various shapes such as polygonal, oval, and the like other than rectangular.

The frame 110 may be formed of various materials such as plastic, metal, wood, cloth, and rubber. For example, the frame 110 may be formed of a plastic synthetic resin that is easy to mold.

The protrusions 120 protrude from the inner surface of the frame 110 and extend along the inner surface of the frame 110. For example, the protrusion 120 may extend in the width direction of the frame 110. The protrusion height of the protrusion 120 has a proper height so that the protrusion 120 can be inserted well into the hair. For example, the height of the protrusion 120 may be set to correspond to the distance between the scalp and the head surface by the hair.

The side surface of the protrusion 120 may be formed in a rectangular shape as shown in FIG. However, the present invention is not limited thereto. The side surface of the protrusion 120 may have a trapezoidal shape whose base is longer than the upper side.

The protrusion 120 may be formed integrally with the frame 110. In this case, the protruding portion 120 may be made of the same material as the frame 110. However, the present invention is not limited thereto, and the protrusion 120 may be configured differently from the frame 110. For example, the frame 110 may be made of a plastic material and the protrusion 120 may be made of a rubber material. In this case, the protrusion 120 may be attached to the inner surface of the frame 110 through a separate adhesive member.

The protrusion 120 includes a first sub-protrusion 121 and a second sub-protrusion 122. The first sub-protrusion 121 and the second sub-protrusion 122 extend parallel to each other and are spaced apart from each other. As shown in FIG. 1, the first sub-protrusion 121 and the second sub-protrusion 122 are alternately arranged. 1, the first sub-protrusion 121 is arranged at the upper end of the frame 110 and the second sub-protrusion 122 is arranged at the lower end of the frame between the first sub-protrusion 121 As shown in FIG.

The second sub protruding portion 122 is parallel to the first sub protruding portion 121 and is spaced apart from the first sub protruding portion 121 and has a portion that partially overlaps with the first sub protruding portion 121. See FIG. 2 for a detailed description.

Referring to FIG. 2, one side of the upper surface of the first sub-protrusion 121 extends below one side of the upper surface of the second sub-protrusion 122 facing the same. Thus, a portion of the second sub-protrusion 122 overlaps the first sub-protrusion 121 between the first sub-protrusions 121.

In this case, the length a of the portion of the second sub protruding portion 122 that partially overlaps the first sub protruding portion 121 may be 3% or more of the total extended length 1 of the second sub protruding portion 122 have. If the length a of the portion of the second sub-protrusion 122 partially overlapping the first sub-protrusion 121 is less than 3% of the total extended length 1 of the second sub-protrusion 122, The hair can not be fixed well by the projections 121 and 122, and the headband 100 can flow down from the hair well. A detailed description thereof will be given later.

Referring to FIG. 3, as the second sub-protrusion 122 partially overlaps with the first sub-protrusion 121, the end surface of the second sub-protrusion 122 in the cross-sectional view taken along line III-III ' (Not shown).

The upper surfaces of the first sub protruding portion 121 and the second sub protruding portion 122 may be bent as shown in Fig. For example, the top edge of the first sub-protrusion 121 and the top edge of the second sub-protrusion 122 may be rounded. In this case, since sharp edges are minimized on the upper surfaces of the first sub-protrusion 121 and the second sub-protrusion 122, scalp compression by the first sub-protrusion 121 and the second sub-protrusion 122 can be minimized And the damage of the scalp due to the edges of the first sub-protrusion 121 and the second sub-protrusion 122 can be minimized.

The headband 100 according to an embodiment of the present invention includes a protrusion 120 extending along the inner surface of the frame 110. [ In particular, the protrusions 120 are configured to be long and flat compared to the sharp protrusions of the conventional headband. Thus, the area of the portion where the protruding portion 120 and the scalp contact with each other can be wider than that of the sharp-shaped protruding portion. In this case, the pressure of the scalp by the protrusion 120 can be minimized, and even if the headband 100 is worn for a long time, the fatigue by the protrusion 120 is minimized, and the wearing comfort of the headband 100 can be improved.

In particular, the headband 100 according to an embodiment of the present invention includes a first sub-protrusion 121 and a second sub-protrusion 122 in which the protrusions 120 are alternately arranged, and the second sub-protrusion 122 Protruding portion 121 includes a portion partially overlapping with the first sub-protruding portion 121 between the first sub- Accordingly, it is possible to further suppress the headband 100 from flowing down from the hair. Specifically, the hair inserted between the first sub-protrusion 121 and the second sub-protrusion 122 may be bent in a region where the first sub-protrusion 121 and the second sub-protrusion 122 overlap each other. 2, the first sub-protrusion 121 and the second sub-protrusion 122 are alternately arranged. Therefore, the first sub-protrusion 121 and the second sub- May alternatively be arranged at the upper and lower ends of the frame 110. Thus, the hair inserted between the first sub-protrusion 121 and the second sub-protrusion 122 can be repeatedly bent, and the binding force between the protrusions 121, 122 and the hair can be further improved. Thus, it is possible to effectively suppress the headband 100 from flowing down from the hair. It can be understood that the binding force of both hands is further improved when the finger pod is put on the finger than simply touching the finger.

In this case, since the length a of the portion of the second sub protruding portion 122 overlapping with the first sub protruding portion 121 is 3% or more of the total length l of the extended second sub protruding portion 122, Protuberance 121 and the second sub-protuberance 122, and the hair can be effectively bound to the protuberance 120. [0064]

In particular, when the headband 100 is worn on the wig, the hair of the wig is thinner and weaker than natural hair, so that the headband 100 can easily flow down. However, according to one embodiment of the present invention, the first sub-protrusion 121 and the second sub-protrusion 122 overlap each other, and the portion of the second sub-protrusion 122 overlapping the first sub- Since the length a is at least 3% of the total extended length l of the second sub-protrusion 122, a thin, weak wig hair is also sufficient between the first and second sub-protrusions 121 and 122 And the binding force between the hair and the protrusion 120 can be increased. If the length a of the portion of the second subdirection 122 overlapping with the first subdirection 121 is less than 3% of the total extended length l of the second subdirection 122, The weak wig hair may not be sufficiently flexed between the first sub protruding portion 121 and the second sub protruding portion 122 and the binding force between the hair and the protruding portion 120 may weaken, As shown in FIG.

Meanwhile, since the headband 100 according to an embodiment of the present invention includes the protrusion 120 extending along the inner surface of the frame 110, the durability of the headband 100 can be improved. In detail, the headband 100 may be formed through an injection process. A typical headband may include protrusions having sharp top surfaces on their inner sides. The mold for manufacturing the headband may be composed of two blocks. In the case where the two mold blocks are formed in the width direction of the headband, the mold may be caught by the protruding portion protruding from the inner side of the headband, Therefore, the two mold blocks are configured to be opened in the longitudinal direction of the headband, i.e., in the direction of the inner side surface and the direction of the outer side of the frame. That is, the mold is composed of a mold block corresponding to the outer surface of the frame of the headband and a mold block corresponding to the inner surface of the frame, and the mold block is opened and separated in the longitudinal direction of the headband after injection molding. In this case, the problem that the mold block is caught by the protrusions formed on the inner side of the frame may not occur. However, in this case, the frame of the headband may be difficult to be bent while being bent in an arc shape. That is, if the headband frame is curved in the arc shape, the mold block corresponding to the inner side of the frame can be caught at both ends of the arc-shaped frame. Thus, in this case, the mold is configured to form a flat, band-shaped frame that is not bent. After the flat strip-shaped frame is separated from the mold, the band-shaped headband is bent in the arc shape to produce the final headband. However, in this manufacturing method, there is a disadvantage that an additional process of bending a flat headband is added and fatigue accumulates in the headband frame in the process of bending the headband, weakening the rigidity of the frame.

In contrast, the headband 100 according to an embodiment of the present invention includes a protrusion 120 extending along the inner surface of the frame, and the protrusions 120 are overlapped with each other, and the first sub- 121 and a second sub-protrusion 122. This structure of the protrusion 120 makes it possible to configure the mold block to be opened in the width direction of the headband 100. That is, since the first sub protruding portion 121 and the second sub protruding portion 122 extend in the width direction of the frame 110, the mold block does not need to be configured to correspond to the inner side surface and the outer side surface of the frame 110 , The mold block may be composed of the upper end portion of the width of the frame 110 and the lower end portion of the width. In this case, the mold block can be opened in the direction of the upper end portion and the lower end portion of the width of the frame 110, and the problem that the mold-starting mold block is caught by the protrusion 120 and is not deformed may not occur. Particularly, in this case, since the mold block is composed of the upper and lower portions of the width of the frame 110, the arc-shaped frame 110 can be injection-molded, and the process of bending the frame 110 in the arc- Can be omitted. Thus, the fatigue applied to the frame 110 in the bending process can be suppressed, and the problem of weakening the durability of the frame 110 can be improved.

In particular, according to one embodiment of the present invention, the first sub-protrusion 121 and the second sub-protrusion 122 overlap each other, so that the first sub-protrusion 121 and the second sub- Can serve as ribs for reinforcing the rigidity of the frame 110. [ That is, since the first and second sub-protrusions 121 and 122 extend along the inner surface of the frame 110 and are alternately arranged to overlap with each other, the frame 110 is formed on the inner surface of the frame 110, There may be rigid rib structures that reinforce the stiffness of the < RTI ID = 0.0 > Therefore, even if the thickness of the frame 110 is thin, the first sub protruding portion 121 and the second sub protruding portion 122 can reinforce the insufficient rigidity of the frame 110, and the durability of the headband 100 is further improved Can be improved.

According to an embodiment of the present invention, since the rigidity of the frame 110 is reinforced by the first sub protruding portion 121 and the second sub protruding portion 122 which are overlapped with each other, the rigidity of the headband 100 May have a thickness that is about 30% thinner than a conventional headband that does not extend along the inner surface of a conventional headband or frame that includes protrusions that do not overlap with each other and that includes sharp-shaped protrusions, , The same or stronger durability. In particular, since the headband 100 according to an embodiment of the present invention can have a thinner thickness than the conventional headband, the amount of synthetic resin necessary for forming the headband 100 can be reduced, May occur. In addition, since the process of bending the frame 110 in the arc shape in the process of manufacturing the headband 100 can be omitted, the effect of reducing the manufacturing cost by omitting the process can be maximized.

4A and 4B are plan views of an inner surface of a headband according to another embodiment of the present invention.

The first distance b between the first sub protruding portion 421 and the second sub protruding portion 422 is greater than the second spacing distance c between the second sub protruding portion 422 and the third sub protruding portion 423 ). In this case, the ratio of the first spacing distance b to the second spacing distance c may be 1: 1.5 or more.

Referring to FIG. 4B, the protrusion 420 may include a first sub protrusion 421, a second sub protrusion 422, and a fifth sub protrusion 425.

The fifth sub-protrusion 425 is parallel to the first sub-protrusion 421, is spaced apart from the second sub-protrusion 422, and partially overlaps with the second sub-protrusion 422.

The separation distance e between the fifth sub-protrusion 425 and the fifth sub-protrusion 425 and the adjacent first sub-protrusion 421 is equal to the distance between the first sub-protrusion 421 and the second sub-protrusion 422, (B). The separation distance e between the fifth sub protruding portion 425 and the fifth sub protruding portion 425 and the adjacent first sub protruding portion 421 is greater than the distance between the fifth sub protruding portion 425 and the second sub protruding portion 422, (D).

In this case, the distance b between the first sub-projection 421 and the second sub-projection 422 and the distance d between the second sub-projection 422 and the fifth sub- The ratio of the distance between the fifth protruding portion 425 and the fifth protruding portion 425 and the distance between the adjacent first protruding portion 421 may be 1: 1: 1.5 or more.

4A and 4B, the third sub-protrusion 423, the fourth sub-protrusion 424, and the fifth sub-protrusion 425 are further configured, so that the binding force of the protrusion 420 and the hair is further improved . In other words, the thin and weak hair is held between the first sub protruding portion 421 and the second sub protruding portion 422 with a narrow gap between the sub protruding portions and between the third sub protruding portion 423 and the fourth sub protruding portion 424, Between the sub-protruding portion 422 and the fifth sub-protruding portion 425, and the coarse, The hair is bound to the protrusion 420 between the second sub-protrusion 422 and the third sub-protrusion 423 having a large gap between the sub-protrusions or between the fifth sub-protrusion 425 and the first sub-protrusion 421 . In particular, in the case of curly hair, the hair may be entangled with each other due to the curvature of the hair, but according to another embodiment of the present invention, the entangled hairs are divided into the second sub protruding portion 422 having a large gap between the sub- It is possible to engage with the protrusion 420 between the protruding portions 423 or between the fifth sub protruding portion 425 and the first sub protruding portion 421 so that the headband does not flow well even in the curled hair.

Therefore, even if the type and shape of the hair are varied, the headband 100 can be strongly bound to the hair, and the problem of the headband 100 flowing down can be further suppressed.

5A and 5B are plan views of an inner surface of a headband according to another embodiment of the present invention. The headband according to yet another embodiment of the present invention may be used in an embodiment of the present invention, except that it includes first sub-protrusions 521, 523 and second sub-protrusions 522, 524 that are partially different in width It is the same as the headband. Therefore, redundant description will be omitted.

Referring to FIG. 5A, the protrusion 520 includes a first sub-protrusion 521 and a second sub-protrusion 522. The width of the first sub projecting portion 521 in the region where the first sub projecting portion 521 and the second sub projecting portion 522 overlap is smaller than the width of the first sub projecting portion 521 in the other region.

Here, the width w3 of each of the first and second sub-protrusions 523 and 524 may gradually become smaller toward the area where the first and second sub-protrusions 523 and 524 overlap each other have.

According to other embodiments of the present invention, the widths of the first sub protrusions 521 and 523 and the second sub protrusions 522 and 524 are greater than the widths of the first sub protrusions 521 and 523 and the second sub protrusions 522 and 524 ) Is small in the overlapping area, the rigidity of the headband can be maintained to be excellent, and the headband can be strongly bound to the head of a thin, weak hair. That is, the widths of the first sub-projections 521, 523 and the second sub-projections 522, 524 in the region where the first sub-projections 521, 523 and the second sub-projections 522, The first sub protruding portions 521 and 523 and the second sub protruding portions 522 and 524 can reinforce the rigidity of the frame 110 more strongly.

Accordingly, the headband can be effectively bound to various types of hair.

6A to 6C are cross-sectional views of a headband according to another embodiment of the present invention. The headband according to still another embodiment of the present invention may include a first sub-protrusion 621, a second sub-protrusion 623, and a second sub-protrusion 625, and a second sub-protrusion 622, Is the same as the headband according to one embodiment. Therefore, a duplicate description thereof will be omitted.

Referring to FIG. 6A, the lower surface of each of the first sub protruding portion 621 and the second sub protruding portion 622, which is in contact with the inner surface of the frame 110, is smaller than the upper surface area. As shown in FIG. 6A, the first sub-protrusion 621 and the second sub-protrusion 622 may have a trapezoidal shape whose upper side is longer than the base side.

That is, the space between the lower surface of the first sub-protrusion 621 and the lower surface of the second sub-protrusion 622 is larger than the space between the upper surface of the first sub-protrusion 621 and the upper surface of the second sub-protrusion 622.

In this case, the hair can be more firmly bound in the region where the first sub protruding portion 621 and the second sub protruding portion 622 overlap with each other. Since the space between the upper surface of the first sub projecting portion 621 and the upper surface of the second sub projecting portion 622 is narrower than the space between the lower surface of the first sub projecting portion 621 and the lower surface of the second sub projecting portion 622, The hair bound between the sub protruding portion 621 and the second sub protruding portion 622 may be difficult to escape into the space between the upper surface of the first sub protruding portion 621 and the upper surface of the second sub protruding portion 622, The binding force between the hair and the protrusion can be strengthened.

Referring to FIG. 6B, the lower surface of each of the first sub protruding portion 623 and the second sub protruding portion 624, which is in contact with the inner surface of the frame 110, is larger than the upper surface area. 6B, the cross section of the first sub protruding portion 623 and the second sub protruding portion 624 may be a triangular shape or a trapezoidal shape whose upper side is shorter than the base side.

In this case, the area of the contact surface where the first sub-protrusion 623 and the second sub-protrusion 624 are in contact with the inner surface of the frame 110 is larger than the area of the upper surface of the first sub-protrusion 623 and the second sub- It is wider.

Therefore, the effect of reinforcing the rigidity of the frame 110 by the first sub protruding portion 623 and the second sub protruding portion 624 can be further increased. That is, since the area of the lower surface of the first sub protruding portion 623 and the surface of the second sub protruding portion 624 is larger than the area of the upper surface of the first sub protruding portion 623 and the second sub protruding portion 624, The effect of increasing the thickness of the rib that reinforces the rigidity is generated, and the rigidity of the frame 110 can be further strengthened.

6C, the area of the lower surface of the first sub-protrusion 625 contacting the inner surface of the frame 11 is smaller than the area of the upper surface, and the inner surface of the frame 110 of the second sub- The area of the lower surface which is tangent is larger than the area of the upper surface. As shown in FIG. 6C, the first sub-protrusion 625 has a trapezoidal shape whose upper side is longer than the base and the second sub-protrusion 626 has a triangular shape or a trapezoidal shape whose upper side is shorter than the base side do.

When the cross section of the first sub-protrusion 625 and the second sub-protrusion 626 is configured as shown in FIG. 6C, the binding force of the headband and the hair can be improved and the rigidity of the frame 110 can be reinforced. That is, since the area of the upper surface of the first sub-protrusion 625 is larger than the area of the lower surface, the hair may hardly protrude from the lower surface of the first sub-protrusion 625 to the upper surface of the first sub-protrusion 625. Thus, the binding force between the hair and the headband can be improved. Since the area of the lower surface of the second sub-protrusion 626 is larger than the area of the upper surface, the area of the contact surface where the second sub-protrusion 626 contacts the inner surface of the frame 110 is widened and the area of the second sub- ) Can be improved. Thus, the rigidity and binding force of the headband can be improved at the same time.
