Description

Technical Field

[0001] The present invention relates to a hairpin.

Background Art

[0002] Normally, human hair grows at a certain inclined angle from the scalp, and grows while curving in the same single direction to create a hair growth direction.

[0003] For this reason, hair hardly has its own volume, and it is difficult to create a desired hairstyle. Furthermore, for people with low hair growth inclination, the hair closely adheres to the scalp, sinks greatly as a whole, making it more difficult to create a style, and when hair loss occurs with aging, these features become more pronounced, leading to great distress and stress.

[0004] To solve such volume problems, hairpins and roll-shaped tools have been introduced, but the tools conventionally used for hair root volume treatment have the drawback that it is difficult to correct the part close to the hair root, that is, the part near the base of the hair.

[0005] In addition, when setting a hairstyle using a conventional hair dryer, a brush or the like will be used, so the user has to hold the hair dryer and the brush with both hands respectively while looking in the mirror, apply heat to the hair with one hand, and set the hairstyle with the brush in the other hand, which has the problem of difficult and cumbersome operations. Therefore, the temporary styling and care method using a hair dryer leads to the problem that a desired shape cannot be obtained unless the user is an expert.

[0006] Accordingly, there has been a demand for a tool that can be applied to easily utilize the volume at the hair root compared with the prior art.

[0007] Background art related to the present invention is disclosed in Korean Patent Laid-Open Publication No. 10-2021-0011674.

Summary of Invention

[0008] The present invention aims to solve the problems of the prior art described above and to provide a hairpin that can easily and effectively enhance hair root volume compared to conventional methods.

[0009] However, the technical problems that the embodiments of the present invention aim to solve are not limited to those described above, and other technical problems may exist. [Means for solving the problem]

[0010] As a technical means for achieving the aforementioned technical challenges, a hairpin according to one embodiment of the present invention includes a plurality of upper base members, each extending diagonally but spaced apart and adjacent to each other in the left-right direction; a plurality of lower base members, located below the plurality of upper base members, extending intersecting the extension direction of the plurality of upper base members and spaced apart and adjacent to each other in the left-right direction; and a plurality of comb teeth formed to protrude downward from each of the plurality of upper base members and the plurality of lower base members, wherein at least one of the plurality of lower base members may be hinged at one end to one end of the plurality of upper base members and at the other end to the other end of the plurality of upper base members, so that the spacing of the plurality of comb teeth in the left-right direction can be increased or decreased.

[0011] In a hairpin according to one embodiment of the present invention, at least some of the comb teeth protruding downward from the plurality of upper base members are provided passing through the overlapping portion of the plurality of lower base members, and the comb teeth have a circular cross-section and can function as hinges provided passing through the lower base members.

[0012] In a hairpin according to one embodiment of the present invention, the hinge connection can be achieved by the hinge function of the teeth of the comb.

[0014] In a hairpin according to one embodiment of the present invention, the second lower base member is hinged at one end to one end of the first upper base member and at the other end to the other end of the second upper base member, and the fourth lower base member is hinged at one end to one end of a fifth upper base member, which is adjacent to the left side of the fourth upper base member among the plurality of upper base members, and at the other end to the other end of the third upper base member.

[0015] A hairpin according to one embodiment of the present invention may further include a left-side handle protruding to the left from the first upper base member and a right-side handle protruding to the right from the third upper base member.

[0016] In a hairpin according to one embodiment of the present invention, each of the plurality of upper base members and the plurality of lower base members may be formed such that both ends in the extension direction are located lower than the center in the extension direction. [Effects of the Invention]

[0017] According to the above-described means for solving the problems of the present invention, a user can place the present pin in an expanded state to insert comb teeth into hair, and can reduce the present pin in the expanded state to allow the comb teeth to grip the hair. At this time, the more the plurality of comb teeth are positioned at the longitudinal center of the upper base member, the higher the height, and the more the comb teeth are positioned at the longitudinal center of the lower base member, the higher the height, so that the hair can be lifted, whereby root volume of the hair is formed, and hair flow can be corrected.

[0026] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings so that those with ordinary skill in the art to which the present invention pertains can easily implement it. However, the present invention can be implemented in a variety of different ways and is not limited to the embodiments described herein. Furthermore, in order to clearly illustrate the present invention, parts that are not relevant to the description have been omitted from the drawings, and similar parts have been denoted by similar reference numerals throughout the specification.

[0029] Throughout this specification, when a part is said to "include" a component, unless otherwise stated, this means that it may include other components rather than excluding them.

[0030] In addition, in the description of embodiments of the present invention, terms related to direction and position (such as upper side, top, upper end, lower side, lower part, lower end, front, rear, left side, right side, etc.) are defined based on the arrangement of each component shown in the figure. For example, in Figure 1, the direction generally towards 12 o'clock is the upper side, the part generally towards 12 o'clock is the upper part, the end generally towards 12 o'clock is the upper end, the direction generally towards 6 o'clock is the lower side, the part generally towards 6 o'clock is the lower part, the end generally towards 6 o'clock is the lower end, the 2 o'clock direction is the front, the 8 o'clock direction is the rear, the 10 o'clock direction is the left side, and the 4 o'clock direction is the right side.

[0031] This invention relates to a hairpin.

[0032] The following describes a hairpin (hereinafter referred to as "this pin") according to one embodiment of the present invention.

[0033] Referring to Figures 1 to 8, this pin includes multiple upper base members 1.

[0034] Referring to Figure 1, the multiple upper base members 1 each extend diagonally and are arranged adjacent to each other with space between them in the left-right direction.

[0035] Furthermore, referring to Figures 1 to 8, this pin includes a plurality of lower base members 2 positioned below a plurality of upper base members 1.

[0036] Referring to Figure 2, the multiple lower base members 2 extend so as to intersect (cross) the extension direction of the multiple upper base members 1, and are arranged adjacent to each other in the left-right direction with a gap between them.

[0037] In other words, the multiple upper base members 1 are arranged with spacing between them in the left-right direction, but may be arranged diagonally so as to form an angle with respect to the left-right direction, and the multiple lower base members 2 are arranged with spacing between them in the left-right direction below the multiple upper base members 1, but may be arranged diagonally so as to form an angle with respect to the left-right direction while their extension direction intersects with the extension direction of the upper base members 1.

[0038] Referring to Figures 1 to 8, this pin includes multiple comb teeth 3. The comb teeth 3 may have a shape in which the cross-section narrows towards the bottom. Referring to Figure 3, the comb teeth 3 protrude downward from each of the multiple upper base members 1 and the multiple lower base members 2.

[0039] For example, referring to Figure 3, comb teeth 3 may be formed at one end and the other end of each of the multiple upper base members 1, and comb teeth 3 may be formed in the longitudinal middle of each of the multiple upper base members 1. In addition, at least some of the comb teeth 3 of the upper base member 1 may penetrate the overlapping lower base member 2 and protrude downward. For this purpose, referring to Figure 4, the lower base member 2 may have a hole 21 through which the comb teeth 3 formed on the upper base member 1 pass.

[0040] Furthermore, referring to Figure 3, the teeth 3 of the comb can be formed between the portion of the upper base member 1 through which the teeth of the comb penetrate the lower base member 2.

[0041] Furthermore, referring to Figure 3, at least some of the teeth 3 of the comb form a group adjacent to each other in the left-right direction, and multiple such groups may be formed.

[0042] Furthermore, referring to Figure 3, the multiple comb teeth 3 may be arranged to extend in the direction toward the center of the main pin, so as to face toward the center of the main pin.

[0043] To allow the lateral spacing between the teeth of the comb to be increased or decreased, at least one of the multiple lower base members 2 may be hinged at one end to one end of the multiple upper base members 1 and at the other end to the other end of the multiple upper base members 1. In other words, to allow the lateral spacing between the teeth 3 of the comb within a group to be increased or decreased, at least one of the multiple lower base members 2 may be hinged at one end to one end of the multiple upper base members 1 and at the other end to the other end of the multiple upper base members 1.

[0044] This will be explained in detail below. For reference, in the present invention, one end of the base members 1 and 2 can mean the rear end, which is the end that faces backward, and the other end can mean the front end, which is the end that faces forward.

[0045] Referring to Figure 1, among the multiple upper base members 1, the leftmost first upper base member 1a may have a shorter extension length than the second upper base member 1b adjacent to its right. Also, among the multiple upper base members 1, the rightmost third upper base member 1c may have a shorter extension length than the fourth upper base member 1d adjacent to its left. In this case, the third upper base member 1c may be provided such that its front end is located in front of the front end of the first upper base member 1a. Furthermore, the second upper base member 1b and the fourth upper base member 1d may be located between the first upper base member 1a and the third upper base member 1c, and one or more other upper base members 1 may be provided as needed. For example, the fifth upper base member 1e adjacent to the left of the fourth upper base member 1d may be located.

[0046] Referring to Figure 3, among the multiple lower base members 2, the leftmost first lower base member 2a may have a shorter extension length than the second lower base member 2b adjacent to its right. Also, among the multiple lower base members 2, the rightmost third lower base member 2c may have a shorter extension length than the fourth lower base member 2d adjacent to its left. In this case, the third lower base member 2c may be provided such that its front end is located behind the front end of the first lower base member 2a. Furthermore, the second lower base member 2b and the fourth lower base member 2d may be located between the first lower base member 2a and the third lower base member 2c, and one or more other lower base members 2 may be provided as needed.

[0047] Referring to Figure 3, the first lower base member 2a can be hinged at one end to the other end of the first upper base member 1a and at the other end to the other end of the second upper base member 1b. The third lower base member 2c can be hinged at one end to one end of the fourth upper base member 1d and at the other end to the other end of the third upper base member 1c.

[0048] Furthermore, the second lower base member 2b can be hinged at one end to one end of the first upper base member 1a and at the other end to the other end of the second upper base member 1b.

[0049] Furthermore, the fourth lower base member 2d can be hinged at one end to one end of the fifth upper base member 1e and at the other end to the other end of the third upper base member 1c.

[0050] Furthermore, while some of the multiple upper base members 1 may be positioned so that their longitudinal intermediate portions overlap with some of the multiple lower base members 2, the portions of the upper base members 1 that overlap with the lower base members 2 in the longitudinal intermediate portions may be hinged together with the lower base members 2.

[0051] Furthermore, hinge connections can be implemented as follows:

[0052] The hinged portion may be the part of the upper base member 1 where the comb teeth 3 overlap and protrude downward through the lower base member 2. That is, the comb teeth 3 may have a circular cross-section, thereby enabling the hinge connection. In other words, in the present invention, the hinge connection can be achieved by the hinge function of the comb teeth 3 that protrude from the upper base member 1 and penetrate the lower base member 2.

[0053] As mentioned above, referring to Figures 5 and 6, when the first upper base member 1a and the third upper base member 1c move away from each other, the pin expands in the left-right direction due to the hinge connection between the multiple upper base members 1 and the multiple lower base members 2, and the spacing between the multiple comb teeth in the left-right direction may widen. Referring to Figures 1 and 2, when the first upper base member 1a and the third upper base member 1c move towards each other, the pin that was expanded by the hinge connection between the multiple upper base members 1 and the multiple lower base members 2 contracts in the left-right direction, and the spacing between the multiple comb teeth 3 in the left-right direction may narrow.

[0054] Referring to Figures 3 and 6, each of the multiple lower base members 2 may have a sawtooth section formed at one end and the other end, including multiple grooves 29 recessed in the circumferential surface. Each of the multiple upper base members 1 may also have a projection 19 formed at one end and the other end, projecting in the direction toward the other side and the one side respectively, and insertable into the groove 29. The projection 19 can be inserted into one of the multiple grooves 29 of the sawtooth section, and if the displacement angle between the extension direction of the upper base member 1 and the extension direction of the lower base member 2 changes by an angle greater than a preset angle, the projection 19 can detach from the groove 29 into which it was inserted and be inserted into another groove 29. By inserting the projection 19 into such a groove 29, the state of the pin formed by the changing lateral distance between the first upper base member 1a and the third upper base member 1c can be fixed, and since multiple grooves 29 are provided, the lateral distance between the first upper base member 1a and the third upper base member 1c can be changed, thereby changing the state of the pin. Also, referring to Figure 3, at least one of the grooves may be longer than the others.

[0055] Referring to Figures 1 to 8, the pin may include a left handle 4 protruding to the left from the first upper base member 1a and a right handle 5 protruding to the right from the third upper base member 1c. This allows the user to expand the pin by gripping the left handle 4 and the right handle 5 respectively and spreading them apart to increase the distance between them, and to contract the pin (a state in which the distance between the comb teeth 3 is reduced compared to the expanded state) by gripping the left handle 4 and the right handle 5 respectively and narrowing the distance between them.

[0056] Furthermore, referring to Figures 7 and 8, each of the multiple upper base members 1 and the multiple lower base members 2 may be formed such that both ends in the extension direction are positioned lower than the center in the extension direction.

[0057] Specifically, referring to Figure 7, each of the multiple upper base members 1 may be formed in a shape that is bent (curved) so that it is positioned higher as it approaches the center in its respective extension direction. These upper base members 1 may be arc-shaped. This allows the comb teeth 3 to be positioned higher than the other comb teeth the closer they are to the longitudinal center of the upper base member 1. This allows multiple comb teeth 3 to be directed toward a central point, which can reduce the squeaking sensitivity when converting the pin to an expanded and contracted state. Furthermore, since at least a part of the human head may have a curved surface similar to a sphere, the rounded part of the head can be grasped accordingly.

[0058] Furthermore, although not shown in detail in the drawings, as can be seen in Figure 8, the multiple lower base members 2 may be bent (curved) so that they are positioned higher as they move towards the center in their respective extension directions. These lower base members 2 may be arc-shaped. This allows the comb teeth 3 to be positioned higher than other comb teeth 3 the closer they are to the longitudinal center of the lower base member 2.

[0059] With this type of pin, the user can extend the pin to insert the comb teeth 3 between the hairs, and then retract the pin to allow the comb teeth 3 to grip the hair. In this case, the height increases as the comb teeth 3 are positioned closer to the longitudinal center of the upper base member 1 and closer to the longitudinal center of the lower base member 2, allowing the hair to be lifted. This creates volume at the root of the hair and can correct the hair flow. The user can ensure the effect of creating volume at the root of the hair or correcting the hair flow by removing the pin from the hair while it is gripping the hair (for example, by moving it upwards). Alternatively, the hair can be dried while it is gripping with the pin. This pin can be used in a variety of other ways.

[0060] Furthermore, referring to Figures 3 and 6 for reference, this pin allows multiple comb teeth to form a square (for example, a rhombus), and this square shape can be formed whether the pin is in an expanded or unexpanded state.

[0061] The above description of the present invention is illustrative, and a person with ordinary skill in the art to which the invention pertains will understand that it can be easily modified into other specific forms without altering the technical idea or essential features of the invention. Therefore, the embodiments described above should be understood to be illustrative in all respects and not limiting. For example, each component described in a single form can be implemented in a distributed manner, and similarly, components described as distributed can be implemented in a combined manner.

[0062] The scope of the present invention is indicated by the claims set forth below rather than by the detailed description above, and all modifications or alterations derived from the meaning and scope of the claims and the concept of equivalents thereto should be interpreted as being included within the scope of the present invention.
