Hair extensions with pre-prepared knots and how to tie them

Abstract

To provide a hair extension with a knot prepared in advance, which can be stably and quickly attached to natural hair with one loop without using an adhesive or the like, and a method for tying the knot. [Solution] This hair extension has a hair bundle 3 (including an artificial hair bundle) at one or both ends of a binding thread 100, and the binding thread 100 is tied to form one loop (third loop 130). When natural hair is inserted into the loop (third loop 130) and fastened, if a specific surface seen from a direction perpendicular to the longitudinal direction of the natural hair is considered to be a plane and the opposite side of the plane is considered to be a bottom, one thread Z is arranged on the plane side and two threads X and Y are arranged on the bottom side. Furthermore, the two threads X and Y on the bottom side are arranged offset to the longitudinal tip side and longitudinal base side of the natural hair, respectively, based on the position of the one thread Z on the plane side.

Description

[Technical Field]

[0001] The present invention relates to the technical field of hair extensions. [Background technology]

[0002] Conventionally, various methods have been devised for attaching hair extensions to natural hair. For example, Patent Document 1 discloses a technique for attaching hair extensions to natural hair using an adhesive (sealing member).

[0003] Furthermore, Patent Document 2 discloses a technique in which two loops are made in advance, and the natural hair is passed through the two loops and then attached by tying a knot. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-256734 [Patent Document 2] Patent No. 7521140 Summary of the Invention [Problem to be solved by the invention]

[0005] While the technology of Patent Document 1 does allow for easy attachment to natural hair, there is a problem that if the adhesive strength is weak, the hair extension itself may come off due to sweat, rain, or even unintentional pulling. On the other hand, if the adhesive strength is too strong, it becomes difficult to remove the hair extension (for example, if you get tired of wearing it). In particular, there is a problem that the adhesive remains on the natural hair, making it difficult to remove cleanly.

[0006] On the other hand, the technology described in Patent Document 2, which does not use adhesive, does not have the above problems. Furthermore, because it can be firmly fixed with two loops, there is little risk of it accidentally coming loose. However, because the user's natural hair needs to be inserted through both loops, the attachment process itself is difficult, time-consuming, and requires practice.

[0007] The present invention has been made to solve these problems, and its objective is to provide hair extensions with pre-prepared knots that can be attached to natural hair stably and quickly with a single loop without using adhesives, and a method for tying the same. [Means for solving the problem]

[0008] In order to solve the above-mentioned problems, the present invention provides a hair extension that has a hair bundle (including an artificial hair bundle) at one or both ends of a binding thread, which is tied to form a loop, and when natural hair is inserted into the loop and fastened, when a specific surface of the natural hair seen from a direction perpendicular to the longitudinal direction is considered to be a plane and the opposite side of the plane is considered to be a bottom surface, one thread is arranged on the plane side and two threads are arranged on the bottom side, and further, the two threads on the bottom side are arranged offset to the longitudinal tip end and longitudinal base end of the natural hair, respectively, based on the position of the one thread on the plane side.

[0009] By adopting this single loop configuration, it is easy to thread your natural hair through. On the other hand, because the single thread on the flat side and the two threads on the bottom side are offset, when fastened (because the natural hair is bent like an L), it can be firmly tied to the natural hair. In other words, there is no problem with the single loop being easy to come off.

[0010] Specifically, the loop is formed by tying one end and the other end of the knotting thread in the following procedure: (a) fix the one end and rotate the other end to create a first loop, with the knotting thread on the one end overlapping the other end; (b) flip the first loop upside down to create a second loop between the first loop and the one end and the other end; (c) fold the other end knotting thread in half and place it underneath the first loop from below; (d) further fold the other end knotting thread in half and place it above the first loop, overhanging it until it protrudes outside the first loop; (e) pinch and pull up the upper part of the first loop that is overlapping the protruding part, and pull it up again so that it overlaps from above the protruding part, creating a third loop that becomes the loop.

[0011] By inserting a rod-shaped object into the loop portion beforehand, it becomes easier to find the loop itself and to insert the natural hair, thereby greatly improving workability.

[0012] The present invention can also be seen as a tying method (method) for fixing a hair extension to natural hair, which comprises a hair bundle and a tie thread for fixing the hair extension to the natural hair, and when the natural hair is inserted through one loop on the tie thread and then fastened, when a specific surface seen from a direction perpendicular to the longitudinal direction of the natural hair is considered to be a plane and the opposite side of the plane is considered to be a bottom surface, one thread is arranged on the plane side and two threads on the bottom side, and further, the two threads on the bottom side are arranged offset to the longitudinal tip end and longitudinal base end of the natural hair, respectively, based on the position of the one thread on the plane side. [Effects of the Invention]

[0013] By applying this invention, it is possible to provide hair extensions with pre-prepared knots that can be attached to natural hair stably and quickly with a single loop without using adhesives, and a method for tying the knots. [Brief explanation of the drawings]

[0015] Hereinafter, a hair extension as an embodiment of the present invention will be described with reference to the accompanying drawings. Please note that in order to make the drawings easier to understand, the size and dimensions of each part are exaggerated and may not necessarily match the actual product. Furthermore, each drawing should be viewed in accordance with the direction of the symbols, and the directions will be expressed as up, down, left, right, front, and back based on these directions.

[0016] <Hair extension composition> The hair extensions of the present invention can be either a single type hair extension 1 with a hair bundle 3 attached to one end of a binding thread 100 as shown in Figure 1(a), or a twin type hair extension 2 with hair bundles 3 attached to both ends of a binding thread 100 as shown in Figure 1(b).

[0017] The present invention is particularly concerned with the knotting method of the knotting thread 100 used for these, that is, forming a loop in the middle of the knotting thread 100 using a specific knotting method.

[0018] How to tie hair extensions (how to make a loop) Hereinafter, a method of tying the knotting yarn 100 to form a loop will be described step by step with reference to Figures 2 to 11. In Figures 2 to 11, the hair bundle 3 is omitted and the knotting yarn 100 is shown as the main focus.

[0019] First, as shown in Figure 2, one end α of the knotting thread 100 is fixed, and the other end β is turned to form a first loop 110. At this time, the knotting thread 100 on the other end β is made to overlap the knotting thread 100 on the one end α (as seen by arrow A).

[0020] Next, as shown in FIG. 3, the first loop 110 is turned upside down (as if twisted) to form second loops 120 between the first loop 110 and one end side α and the other end side β.

[0021] Next, as shown in Fig. 4, the binding thread 100 on the other end side β is folded in half (part X in Fig. 4) and inserted from below (part Y in Fig. 4) into the first loop 110. At this time, the folded part overlaps the underside of the binding thread 100 that forms the lower part of the first loop 110 (part Y in Fig. 4) (part B in the direction of the arrow).

[0022] Next, as shown in Fig. 5, the knotting thread 100 on the other end side β is folded in half and folded upward (part Z in Fig. 5) onto the first loop 110, so that it overlaps the upper side and projects out to the outside of the first loop 110 (part X in Fig. 5). At this time, the folded part overlaps the upper side of the knotting thread 100 that constitutes the upper part of the first loop 110 (part Z in Fig. 5) (part C in the direction of the arrow).

[0023] Next, the upper part of the first loop 110 overlapping the protruding part X in Fig. 5 (part Z in Fig. 5) is pinched and pulled up, and then pulled up further so that it overlaps from above the protruding part X (part Z in Fig. 6). The third loop 130 thus created becomes a loop for inserting the hair bundle.

[0024] For example, if a rod-shaped body 200 is passed through this third loop 130 and one end side α and the other end side β are pulled, a knot like that shown in Figure 10 will be formed. One thread Z exists on the flat surface side (see Figure 8), and two threads X and Y exist on the bottom surface side (see Figure 9). In this case, the two threads X and Y on the bottom surface side are offset in the longitudinal direction of the rod-shaped body 200 (or natural hair) using the position of the one thread Z on the flat surface side as a reference.

[0025] Note that only the third loop 130 is not completely fastened due to the presence of the rod-shaped body 200, and when the rod-shaped body 200 is removed, the third loop 130 becomes exposed. By passing your natural hair (not shown) through this loop and finally fastening it, the hair extensions 1 and 2 are fixed to your natural hair.

[0026] As described above, the present invention is a hair extension having a hair bundle 3 (including an artificial hair bundle) at one or both ends of the binding thread 100, and the binding thread 100 is tied to form one loop (third loop 130). When natural hair is inserted into the loop (third loop 130) and fastened, if a specific surface of the natural hair seen from a direction perpendicular to the longitudinal direction is taken as a plane and the opposite side of the plane is taken as a bottom surface, one thread Z is arranged on the plane side and two threads X and Y are arranged on the bottom side, and further, the two threads X and Y on the bottom side are arranged offset to the longitudinal tip end and longitudinal base end of the natural hair, respectively, based on the position of the one thread Z on the plane side.

[0027] By adopting this single loop (third loop 130) configuration, it is easy to thread the natural hair (it is sufficient to thread it through one loop). On the other hand, by offsetting the single thread Z on the flat side and the two threads X and Y on the bottom side, when fastened (because the natural hair is bent like a dogleg), it can be firmly tied to the natural hair. In other words, there is no problem with the loop (third loop 130) being one, such as it easily coming loose.

[0028] Furthermore, by inserting the rod-shaped body 200 into the loop (third loop 130) part in advance as described above, it becomes easier to find the loop (third loop 130) itself and to insert the natural hair, thereby greatly improving workability.

[0029] <Other configuration examples> In the above and in the claims, the expressions "1" or "2" are used to indicate the number of threads, but in the case of twisted yarn, this refers to the number of threads in a twisted (finished) state, so the concept also includes cases where "1" contains multiple threads.

[0030] It is possible to tie a yarn that already has the hair bundle 3 as described above, or to first make a loop (knot) in the knotting yarn 100 and then form the hair bundle 3 at one or both ends of the loop. The order does not matter. [Explanation of symbols]
