Abstract
The present invention relates to a hair band, and a hair band of an aspect of the present invention includes a frame and a plurality of protrusions protruding from and extending along an inner side surface of the frame. The plurality of projections includes a first sub-projection and a second sub-projection parallel to and spaced apart from the first sub-projection and having a portion overlapping the first sub-projection portion.
Description
Technical Field
The present invention relates to a hair band having an excellent wearing feeling and improved durability.
Background
The hair band is an article for fixing hair to prevent the hair from slipping down and maintaining a modesty style. Currently, the surface of the hair band is beautifully decorated to be widely used as an ornament, and various studies are made in order to make the appearance of the hair band beautiful.
The headband has a circular arc shape corresponding to the shape of the head, and is formed of a plastic material having an elastic force to press the circumference of the head, thereby being worn on the head. However, it is difficult to firmly couple the hair band and the hair only by the elastic force of the hair band, and the wearer feels fatigue due to pressure on the scalp when wearing the hair band for a long time.
However, since the plurality of projections form a pointed shape and press the scalp, there is a problem that fatigue is given to the scalp of the wearer when the scalp is worn for a long time.
In addition, in the case where a plurality of protrusions are arranged along the inner surface of the arc-shaped hair band, the inner surface of the hair band has a complicated structure, and therefore, it is impossible to manufacture the arc-shaped hair band by one-step molding, and to manufacture the hair band by bending the hair band into the arc-shaped hair band after the flat hair band is injection-molded. Fatigue is accumulated on the hair band in the process of bending the hair band into an arc state, so that the rigidity of the hair band is reduced, and the problem that the hair band is easy to break is generated under the condition that the thickness of the hair band is sufficiently thin.
Therefore, a technique for solving the above-described problems is required.
In addition, the foregoing background art is the technical information that the inventors have saved or learned in order to derive the present invention, and therefore, should not be construed as a prior art necessarily disclosed to the public prior to filing the present invention.

When a component is referred to as being "included" in a certain portion, unless otherwise stated, the component may include other components without excluding other components.
The present invention is described in detail below with reference to the attached drawings.
Fig. 1 is a perspective view illustrating a hair band according to an embodiment of the present invention, fig. 2 is a plan view of an inner side of the hair band of fig. 1, and fig. 3 is a sectional view taken along line III-III' of the hair band of fig. 1.
The hair band 100 of one embodiment of the present invention may be a functional part functioning as a hair accessory for wearing on the head to inhibit the falling of hair, or to exhibit various hairstyles.
Referring to fig. 1, a hair band 100 according to an embodiment of the present invention includes a frame 110 and a protrusion 120 protruding from an inner side surface of the frame 110.
The frame 110 may have a substantially thin thickness. For example, the frame 110 may have a thickness of 0.5mm to 10 mm. However, the thickness of the frame 110 may be variously determined according to 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. Although fig. 1 shows the frame 110 having a rectangular outer side and inner side, the outer side and inner side of the frame 110 may be formed in various shapes such as a polygon and an ellipse, in addition to the rectangle.
The frame 110 may be formed of various materials such as plastic, metal, wood, fabric, rubber, etc. For example, the frame 110 may be formed of plastic synthetic resin that is easily molded.
The protrusion 120 protrudes from the inner side surface of the frame 110, and extends along the inner side surface of the frame 110. For example, the protrusion 120 may be elongated in a width (width) direction of the frame 110. The protruding height of the protruding part 120 has an appropriate height such that the protruding part 120 can be easily inserted between hairs. For example, the height of the protrusion 120 may be set to correspond to the distance between the scalp and the surface of the head composed of hair.
As shown in fig. 1, the side surface of the protrusion 120 may be configured in a quadrangular shape. However, the side surface of the protruding portion 120 may be formed in a trapezoidal shape having a larger bottom side than an upper side.
The protrusion 120 may be formed integrally with the frame 110. In this case, the protrusion 120 may be formed of the same material as the frame 110. But not limited thereto, the protrusion 120 may be a different structure 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 side surface of the frame 110 by an additional attaching 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 are extended in parallel and spaced apart from each other. As shown in fig. 1, the first sub-protrusions 121 and the second sub-protrusions 122 are alternately arranged. For example, as shown in fig. 1, the first sub-protrusions 121 are arranged at the upper end of the frame 110, and the second sub-protrusions 122 may be arranged between the first sub-protrusions 121 at the lower end of the frame.
The second sub protrusion 122 is parallel to the first sub protrusion 121 and spaced apart from the first sub protrusion 121, and has a portion partially overlapping the first sub protrusion 121. This is explained in detail with reference to fig. 2.
Referring to fig. 2, a side of an upper face of the first sub-protrusion 121 is elongated more downward than a side of an upper face of the second sub-protrusion 122 opposite thereto. 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 protrusion 122 partially overlapping the first sub protrusion 121 may be 3% or more of the extended total length l of the second sub protrusion 122. 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 extended total length l of the second sub-protrusion 122, the hair may not be well fixed by the protrusions 121 and 122, and the hair band 100 may easily slip off the hair. This will be described in detail later.
Referring to fig. 3, since the second sub-protrusion 122 partially overlaps the first sub-protrusion 121, a cross section of the second sub-protrusion 122 can be located between the first sub-protrusions 121 in a cross-sectional view along line III-III'.
As shown in fig. 3, the upper surfaces of the first and second sub-protrusions 121 and 122 may be bent. For example, the upper surface corners of the first sub protrusion 121 and the second sub protrusion 122 may be chamfered. In this case, since the sharp edges of the upper surfaces of the first and second sub protrusions 121 and 122 are minimized, the scalp can be minimized from being pressed by the first and second sub protrusions 121 and 122, and the scalp can be minimized from being damaged by the edges of the first and second sub protrusions 121 and 122.
The hair band 100 of one embodiment of the present invention includes a protrusion 120 elongated along the inside surface of the frame 110. In particular, the projections 120 are configured to be longer and straight than the sharp projections of the prior art hair band. Therefore, the area of the portion of the protruding portion 120 that contacts the scalp can be wider than the sharp protruding portion. In this case, it is possible to minimize the scalp from being pressed by the bulge 120, and to minimize fatigue caused by the bulge 120 to improve the wearing feeling of the headband 100 even if the headband 100 is worn for a long time.
In particular, the tab 120 of the hair band 100 according to an embodiment of the present invention includes first sub-tabs 121 and second sub-tabs 122 alternately arranged with each other, and the second sub-tabs 122 include portions partially overlapping the first sub-tabs 121 between the first sub-tabs 121. Therefore, the slipping of the headband 100 from the hair can be further suppressed. Specifically, the hair inserted between the first and second sub-protrusions 121 and 122 may be bent at a region where the first and second sub-protrusions 121 and 122 overlap each other. Since the first sub protrusion 121 and the second sub protrusion 122 are alternately arranged, as shown in fig. 2, the overlapping regions of the first sub protrusion 121 and the second sub protrusion 122 can be alternately arranged toward the upper end and the lower end of the frame 110. Therefore, the hairs inserted between the first and second sub-protrusions 121 and 122 can be repeatedly bent, and the coupling force between the protrusions 121 and 122 and the hairs can be further improved. And therefore, slipping of the hair band 100 from the hair can be effectively suppressed. This can be understood as a further increase in the engagement force of the two hands when the fingers are crossed, as compared to simply pressing against the fingers.
In this case, the length a of the portion of the second sub-protrusion 122 overlapping the first sub-protrusion 121 is 3% or more of the extended total length l of the second sub-protrusion 122, so that hairs can be sufficiently bent between the first sub-protrusion 121 and the second sub-protrusion 122, and the hairs can be effectively coupled to the protrusion 120.
In particular, when the headband 100 is worn on a wig, the hair of the wig is thinner and thinner than the natural hair, and thus the headband 100 may easily slip off. However, according to an embodiment of the present invention, the first sub-protrusion 121 and the second sub-protrusion 122 overlap each other, and the length a of the portion of the second sub-protrusion 122 overlapping the first sub-protrusion 121 is more than 3% of the extended total length l of the second sub-protrusion 122, so that the thin and slim wig can be bent sufficiently between the first sub-protrusion 121 and the second sub-protrusion 122 to increase the coupling force between the hairs and the protrusion 120. If the length a of the portion of the second sub-protrusion 122 overlapping the first sub-protrusion 121 is less than 3% of the extended total length l of the second sub-protrusion 122, the thin and thin wig cannot be bent sufficiently between the first and second sub-protrusions 121 and 122, the coupling force between the hairs and the protrusion 120 may be weakened, and thus the headband 100 may easily slip off from the hairs.
In addition, the hair band 100 according to an embodiment of the present invention includes the protrusion 120 elongated along the inner side surface of the frame 110, so that the durability of the hair band 100 can be improved. In particular, for this purpose, the hair band 100 may be formed by an injection molding process. A typical inside face of the hair band may include a projection having a sharpened upper face. The mold for manufacturing the hair band may be composed of two blocks, and when the two mold blocks open the mold in the width direction of the hair band, the mold may be caught by a protrusion protruding from the inner side surface of the hair band and may not be opened. Therefore, the two mold blocks are opened in the longitudinal direction of the hair band, i.e., in the inner side surface direction and the outer side surface direction of the frame. That is, the mold is composed of a mold block corresponding to the outer side surface of the frame of the hair band and a mold block corresponding to the inner side surface of the frame, and the mold blocks are separated from each other in the longitudinal direction of the hair band after injection molding. In this case, the problem that the mold block is caught by the projecting portion formed on the inner side surface of the frame does not occur. In this case, however, the frame of the hair band may not be easily injection molded into a curved arc. That is, in the case where the hair band frame is bent in an arc-shaped state, the mold blocks corresponding to the inner side surfaces of the frame may be caught at both ends of the frame bent in the arc-shaped state. Therefore, in this case, the mold is configured to form a frame in a straight belt shape without being bent. After separating the flat, band-shaped frame from the mold, the band-shaped headband is bent into an arc-shaped configuration to ultimately manufacture the headband. However, this method of manufacturing requires an additional process of bending a flat hair band, and fatigue is accumulated in the hair band frame during bending of the hair band, thereby having a disadvantage of reducing the rigidity of the frame.
On the contrary, the hair band 100 according to an embodiment of the present invention includes the protrusion 120 extended along the inner side of the frame, and the protrusion 120 is formed of the first sub-protrusion 121 and the second sub-protrusion 122 which are overlapped with each other and alternately arranged. This configuration of the projections 120 enables the mold blocks to be configured to open toward the width of the hair band 100. That is, since the first sub protrusion 121 and the second sub protrusion 122 extend in the width direction of the frame 110, the mold blocks do not have to be configured to correspond to the inner side and the outer side of the frame 110, and the mold blocks may be configured by the wide upper end portion and the wide lower end portion of the frame 110. In this case, the mold blocks can be opened toward the wide upper end portion and the wide lower end portion of the frame 110, and a problem that the mold blocks are caught in the protrusion 120 and cannot be opened when the mold is opened can be avoided. In particular, in this case, since the die block is formed by the wide upper end portion and the wide lower end portion of the frame 110, the frame 110 bent in the arc shape can be injection molded, and the step of bending the frame 110 in the arc shape can be omitted. Therefore, fatigue applied to the frame 110 in the bending process can be suppressed, and the problem of the reduction in durability of the frame 110 can be solved.
In particular, according to an embodiment of the present invention, the first and second sub-protrusions 121 and 122 overlap each other, and thus the first and second sub-protrusions 121 and 122 can function as a rib (rib) that reinforces the rigidity of the frame 110 in the overlapping region. That is, the first sub protrusion 121 and the second sub protrusion 122 are extended along the inner surface of the frame 110 and are disposed to be alternately overlapped with each other, so that a strong rib structure for enhancing the rigidity of the frame 110 can be provided on the inner surface of the frame 110. Therefore, even if the thickness of the frame 110 is thin, the first sub-protrusions 121 and the second sub-protrusions 122 can enhance the insufficient rigidity of the frame 110, and thus the durability of the headband 100 can be further improved.
According to an embodiment of the present invention, since the rigidity of the frame 110 is enhanced by the first and second sub-protrusions 121 and 122 overlapping each other, the hair band 100 of an embodiment of the present invention may have a thickness of about 30% thinner than an existing hair band including non-overlapping protrusions or an existing hair band including sharp-shaped protrusions that are not elongated along the inner side of the frame, and may have the same or stronger durability despite of such a thin thickness. In particular, the hair band 100 according to an embodiment of the present invention can have a thinner thickness than the conventional hair band, and thus the amount of synthetic resin required to form the hair band 100 can be reduced, thereby being able to produce an effect of reducing manufacturing costs. In addition, since the process of bending the frame 110 into the arc shape can be omitted in the process of manufacturing the hair band 100, the effect of reducing the manufacturing cost by omitting the process can be further maximized.
Fig. 4a and 4b are plan views of the inner side of a hair band according to another embodiment of the present invention. The hair band according to another embodiment of the present invention is the same as the hair band 100 according to one embodiment of the present invention described with reference to fig. 1 to 3 except that it includes the tab 420 including the first sub-tab 141, the second sub-tab 142, the third sub-tab 143, the fourth sub-tab 144, and the fifth sub-tab 145, and thus, the repeated description thereof will be omitted.
Referring to fig. 4a, the protrusion 420 includes a first sub-protrusion 421, a second sub-protrusion 422, a third sub-protrusion 423, and a fourth sub-protrusion 424.
The third sub protrusion 423 is parallel to the first sub protrusion 421, and is spaced apart from the first sub protrusion 421 by the second sub protrusion 422.
The fourth sub protrusion 424 is parallel to the second sub protrusion 422 and is spaced apart from the second sub protrusion 422 by the third sub protrusion 423.
Wherein a first separation distance b between the first sub protrusion 421 and the second sub protrusion 422 is smaller than a second separation distance c between the second sub protrusion 422 and the third sub protrusion 423. In this case, the ratio of the first spaced distance b to the second spaced distance c may be 1: 1.5 or more.
In addition, referring to fig. 4b, the protrusion part 420 may include a first sub protrusion part 421, a second sub protrusion part 422, and a fifth sub protrusion part 425.
The fifth sub protrusion 425 is parallel to the first sub protrusion 421 and spaced apart from the second sub protrusion 422, and partially overlaps the second sub protrusion 422.
The distance e between the first sub protrusion 421 and the fifth sub protrusion 425 adjacent to the fifth sub protrusion 425 is greater than the distance b between the first sub protrusion 421 and the second sub protrusion 422. And, a spaced distance e between the first sub protrusion 421 and the fifth sub protrusion 425 adjacent to the fifth sub protrusion 425 is greater than a spaced distance d between the fifth sub protrusion 425 and the second sub protrusion 422.
In this case, the ratio of the spaced distance b between the first sub protrusion 421 and the second sub protrusion 422, the spaced distance d between the second sub protrusion 422 and the fifth sub protrusion 425, and the spaced distance e between the first sub protrusion 421 and the fifth sub protrusion 425 adjacent to the fifth sub protrusion 425 may be 1: 1: 1.5 or more.
As shown in fig. 4a and 4b, the third sub-protrusion 423, the fourth sub-protrusion 424, and the fifth sub-protrusion 425 are further configured to further improve the coupling force between the protrusion 420 and the hairs. That is, thin and thin hairs are coupled to the protrusion 420 between the first sub protrusion 421 and the second sub protrusion 422 having a narrow interval between the sub protrusions, between the third sub protrusion 423 and the fourth sub protrusion 424, or between the second sub protrusion 422 and the fifth sub protrusion 425, and thick and strong hairs are coupled to the protrusion 420 between the second sub protrusion 422 and the third sub protrusion 423 having a wide interval between the sub protrusions, or between the fifth sub protrusion 425 and the first sub protrusion 421. Particularly in the case of curling hair, the hair may be twisted with each other due to the twist of the hair, but according to another embodiment of the present invention, the twisted hair may be coupled to the protrusion 420 between the second sub-protrusion 422 and the third sub-protrusion 423 or between the fifth sub-protrusion 425 and the first sub-protrusion 421, which have wide intervals between the sub-protrusions, and thus, even the curling hair band may not easily slip off.
Therefore, despite the variety of hair types and shapes, headband 100 can be firmly bonded to the hair, and the problem of headband 100 slipping off can be further suppressed.
Fig. 5a and 5b are plan views of the inner side of a hair band according to still another embodiment of the present invention. The hair band according to still another embodiment of the present invention is the same as the hair band according to one embodiment of the present invention except that it includes the first sub-protrusions 521 and 523 and the second sub-protrusions 522 and 524 having different widths. And therefore, duplicate explanation is 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-protrusion 521 at the region where the first sub-protrusion 521 overlaps the second sub-protrusion 522 is smaller than the width of the first sub-protrusion 521 at other regions.
Also, the width w1 of the second sub-protrusion 522 of the region where the first sub-protrusion 521 overlaps with the second sub-protrusion 522 is smaller than the width w2 of the second sub-protrusion 522 of the other region.
Referring to fig. 5b, the width of each of the first and second sub-protrusions 523 and 524 in the region where the first and second sub-protrusions 523 and 524 overlap is less than the width w3 of the other regions. Here, the width w3 of each of the first sub-protrusion 523 and the second sub-protrusion 524 may gradually decrease toward an area where the first sub-protrusion 523 overlaps the second sub-protrusion 524.
According to another embodiment of the present invention, the widths of the first sub convex portions 521 and 523 and the second sub convex portions 522 and 524 are reduced in the region where the first sub convex portions 521 and 523 and the second sub convex portions 522 and 524 overlap, so that the rigidity of the hair band can be maintained excellently, and the hair band can be also firmly coupled to the head having thin and thin hair. That is, the widths of the first and second sub-convex parts 521 and 523 and 522 and 524 in the region where the first and second sub-convex parts 521 and 523 and 522 and 524 do not overlap are large, and thus the rigidity of the frame 110 can be further enhanced by the first and second sub-convex parts 521 and 523 and 522 and 524.
Further, since the widths of the first and second sub-protrusions 521 and 523 and 522 and 524 in the region where the first and second sub-protrusions 521 and 523 and 522 and 524 overlap are small, a space between the first and second sub-protrusions 521 and 523 and 522 and 524 is secured in the region where the first and second sub-protrusions 521 and 523 and 522 and 524 overlap, and hairs can be more easily coupled in the space between the first and second sub-protrusions 521 and 523 and 522 and 524. Thus, hair bands that encounter multiple morphologies of hair can be effectively combined as well.
Fig. 6a to 6c are sectional views of a hair band in accordance with still another embodiment of the present invention. The hair band according to still another embodiment of the present invention is the same as the hair band according to an embodiment of the present invention except that it includes the first subsidiary projections 621, 623, 625 and the second subsidiary projections 622, 624, 626 having different sectional shapes. Therefore, a repetitive description thereof will be omitted.
Referring to fig. 6a, the lower surface of each of the first and second sub-protrusions 621 and 622 contacting the inner side surface of the frame 110 is smaller than the upper surface. Therefore, as shown in fig. 6a, the cross-section of the first sub protrusion 621 and the second sub protrusion 622 may be a trapezoidal shape with the upper side longer than the bottom side.
In this case, in the overlapping region of the first sub protrusion 621 and the second sub protrusion 622, the space of the inner side surface of the frame 110 gradually becomes smaller toward the upper surfaces of the first sub protrusion 621 and the second sub protrusion 622. That is, a space between a lower face of the first sub protrusion 621 and a lower face of the second sub protrusion 622 is larger than a space between an upper face of the first sub protrusion 621 and an upper face of the second sub protrusion 622.
In this case, hairs can be more firmly coupled at the region where the first sub-protrusion 621 and the second sub-protrusion 622 overlap each other. That is, a space between the upper surface of the first sub protrusion 621 and the upper surface of the second sub protrusion 622 is smaller than a space between the lower surface of the first sub protrusion 621 and the lower surface of the second sub protrusion 622, and thus, hairs coupled between the first sub protrusion 621 and the second sub protrusion 622 are not easily separated from the space between the upper surface of the first sub protrusion 621 and the upper surface of the second sub protrusion 622, and thus, the coupling force between the hairs and the protrusion can be enhanced.
Referring to fig. 6b, the lower area of each of the first and second subsidiary protrusions 623 and 624 contacting the inner side of the frame 110 is greater than the upper area. Therefore, as shown in fig. 6b, the cross-section of the first subsidiary projection 623 and the second subsidiary projection 624 may be triangular or trapezoidal with the upper side shorter than the lower side.
In this case, the area of the contact surfaces of the first sub protrusion 623 and the second sub protrusion 624 with the inner surface of the frame 110 is larger than the area of the upper surfaces of the first sub protrusion 623 and the second sub protrusion 624.
Accordingly, the effect of enhancing the rigidity of the frame 110 by the first and second subsidiary projections 623 and 624 can be more increased. That is, since the areas of the lower surfaces of the first subsidiary projection 623 and the second subsidiary projection 624 are larger than the areas of the upper surfaces of the first subsidiary projection 623 and the second subsidiary projection 624, the thickness of the rib for reinforcing the rigidity of the frame 110 is increased, and thus the rigidity of the frame 110 can be further increased.
Referring to fig. 6c, the area of the lower side of the first sub protrusion 625 contacting the inner side surface of the frame 110 is smaller than the area of the upper side, and the area of the lower side of the second sub protrusion 626 contacting the inner side surface of the frame 110 is larger than the area of the upper side. Therefore, as shown in fig. 6c, the cross section of the first sub protrusion 625 is a trapezoid with the upper side longer than the lower side, and the cross section of the second sub protrusion 626 is a triangle or a trapezoid with the upper side shorter than the lower side.
The cross-sectional configurations of the first sub protrusion 625 and the second sub protrusion 626 are as shown in fig. 6c, so that the coupling force between the hair band and the hair can be improved, and the rigidity of the frame 110 can be enhanced. That is, the area of the upper surface of the first sub-protrusion 625 is larger than the area of the lower surface, and thus hairs are not easily detached from the lower surface of the first sub-protrusion 625 to the upper surface of the first sub-protrusion 625. Thereby improving the binding force between the hair and the hair band. Further, 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 of the second sub protrusion 626 with the inner surface of the frame 110 is increased, and the rigidity reinforcing effect of the second sub protrusion 626 can be enhanced. Thereby improving the rigidity and the binding force of the hair band at the same time.
The above description of the present invention is intended to be illustrative, and it will be understood by those skilled in the art that the present invention may be easily modified into other specific forms without changing the technical spirit or essential features of the present invention.
