Definitions

  • hair extensions are strands of (artificial) hair that are added to your natural hair. They are used to add length and volume to your hair, or to change your hairstyle, making them a fun accessory for styling. Wearing hair extensions makes it easy to add length and volume to your natural hair, instantly making short hair look longer and more voluminous, and allowing you to try out new styles and hair colors. Removable hair extensions make it easy to change up your style on a daily basis or wear them for special events.
  • Hair extensions are a type of false hair or partial wig that are attached to the wearer's natural hair using some method.
  • other known attachment methods include using adhesives (tape), metal tips, heat-shrink tubing, and elastic thread.
  • Methods recommended for professional use include attaching the extensions to the natural hair using small metal rings called microrings, and using special adhesives to attach the extensions to the natural hair (care should be taken as the adhesive may cause damage to the natural hair).
  • Patent Document 1 states that its objective is to provide a hair extension and attachment method that can be easily attached to hair in a short time without requiring skill or separate tools, and that does not damage natural hair (excerpt from Patent Document 1, paragraph 0005). It also discloses a hair extension and attachment method (Patent Document 1: Title of the Invention) in which "the base end of the false hair bundle is attached with an adhesive, and the base end of a binding thread acting as a fastening means is adhesively fixed to the base end, and an anti-unwinding ring made of a binding thread is fitted to the binding thread so that it can move along the binding thread (excerpt from Patent Document 1, paragraph 0017).”
  • the base end of the false hair strand is attached with an adhesive, so when actually worn, the base end of the false hair strand hardens into one place, forming a lump, which feels uneven to the touch (i.e., it feels like touching a lump that is different from hair). Furthermore, because the base end of the attachment thread is fixed with adhesive and the anti-unwind ring is movably fitted, it feels even more uneven to the touch, which is undesirable.
  • the object of the present invention is to provide hair extensions that are not bumpy to the touch and that can be worn with a natural appearance.
  • the object is to provide hair extensions that blend seamlessly with your natural hair, making them virtually invisible from the outside and maintaining a natural appearance.
  • the invention described in claim 1 is a hair extension made by bundling human hair or hair made of synthetic fibers to be attached to natural hair, characterized in that the base ends of the bundles of multiple hairs are arranged at predetermined intervals on a fibrous attachment base wire, and the base ends of the hair bundles are fixed by wrapping an elastic fibrous wire around them.
  • the invention described in claim 2 is the invention described in claim 1, characterized in that the base end portion of each hair bundle is adhered to a fibrous mounting base wire with an adhesive.
  • the present invention is a hair extension that is an assembly of (multiple) hair strands made of human hair (personal hair) or synthetic fibers that is attached to natural hair.
  • the hair extension of the present invention comprises an attachment base wire, multiple hair strands tied to the attachment base wire at predetermined intervals, and a wound elastic wire that is wound (preferably wrapped so as not to leave any gaps) around the attachment base wire side of the hair strands tied to the attachment base wire at predetermined intervals.
  • the hair extensions of the present invention have multiple strands of hair attached (distributed) at predetermined intervals to the attachment base wire, so the base ends of the false hairs (attached to natural hair) are not concentrated in one place like in conventional extensions, but are distributed at appropriate intervals. Therefore, the hair extensions of the present invention do not feel bumpy to the touch and can be worn in a natural appearance.
  • the wrapped elastic member side of the hair bundle in the hair extension of the present invention is held together by an adhesive, so when the wrapped elastic wire is wrapped around the attachment base wire side of the hair bundle without any gaps, the interaction between the elasticity of the wrapped elastic member and the adhesive (elasticity and adhesiveness) allows the wrapped elastic member to be attached smoothly without falling off.

  • the wound elastic member 4 side of the (plurality of) hair strands 3 that make up the hair extension 1 is held together by an adhesive material 5 (described below using Figures 2 and 3).
  • the attachment base wire 2 can be made from a material selected from artificial fibers such as polyester and natural fibers such as cotton thread (or a bundle of multiple such fibers).
  • the wound elastic wire 4 can be made from a material selected from polyurethane rubber and silicone rubber. The materials and raw materials for the attachment base wire 2 and the wound elastic wire 4 are not limited to those mentioned above, as long as they satisfy the performance requirements of the hair extension 1.
  • a tab P with an inner circumference of a predetermined length (approximately 90 mm) is formed by bundling the mounting base wire 2, for inserting a finger through when pulling the mounting base wire 2. Furthermore, a first loop Ra with an inner circumference of a predetermined length (approximately 7.0 mm) is formed in a portion a predetermined length (approximately 20 mm) inward from the tip, and a second loop Rb with an inner circumference of a predetermined length (approximately 7.0 mm) is formed at a position a predetermined length (approximately 2.0 mm) away from the first loop Ra (i.e., in the mounting base wire 2, the distance between the first loop Ra and the second loop Rb is adjusted to approximately 2.0 mm).
  • Figure 5 shows a method for forming the first loop Ra and the second loop Rb, and the first loop Ra and the second loop Rb are formed by bundling the mounting base wire 2 through the following steps (1) to (4).
  • a second step of forming a first loop Ra by guiding the first edge 14a, which has been guided to the back side of the second edge 14b, to the front side of the second edge 14b (see FIG. 5(b)).
  • a fourth step of adjusting the first loop Ra and the second loop Rb to a predetermined size (a circular or elliptical shape with an inner periphery length of approximately 7.0 mm) by pulling the mounting base wire 2 so as to separate the first end edge 14a and the second end edge 14b.
  • Figure 2 is an explanatory diagram showing a method for producing a hair bundle 3 (which constitutes the hair extension 1). The method for producing the hair bundle 3 will be described with reference to Figure 2.
  • Figure 2(a) about 30 to 50 hairs (human hairs) are aligned on a glass plate 6 so that the tips are positioned at one end of the glass plate 6, and the longitudinal direction of the hairs is perpendicular to the longitudinal direction of the glass plate 6.
  • adhesive 5 (or glue) is applied to the tip-end portions of the hairs (the crosshatched portions in Figure 2(a)), specifically, to the hairs arranged on a portion of the glass plate 6 that is approximately 1/3 to 1/2 the width in the short direction (first application). Then, the adhesive 5 (or glue) is allowed to dry (it is sufficient if it appears dry on the surface), and adhesive 5 (or glue) is applied again (second application).
  • the adhesive 5 applied to the tip side of the hair (the hair placed on a section approximately 1/3 to 1/2 of the width of the glass plate 6 in the short direction) is allowed to dry (it is sufficient if it is dry on the surface), and the glass plate 6 is then removed (dismounted), and the tip side of the section to which the adhesive 5 was applied is cut, leaving the remaining section in the shape of multiple semicircles lined up (see Figure 2(b)).
  • the tip side of the cut hair (the section with multiple semicircles lined up) is then folded over in opposite directions for each semicircle to obtain the hair bundle 3.
  • the shape of the cut end of the hair bundle 3 is formed into a semicylindrical shape (i.e., a flattened semicylindrical shape) with a predetermined thickness by alternately folding over each semicircle in the opposite direction (so that the front and back are reversed).
  • (one) hair bundle 3 is formed from 30 to 50 hairs (human hair) and adhesive 5.
  • Figure 3 is an explanatory diagram showing a method for producing the hair extension 1. Note that a dedicated jig is used when producing the hair extension 1, but the dedicated jig is not shown in Figure 3.
  • FIG 4 shows the state in which the hair bundle 3 is fixed to the attachment base wire 2 by adhering the hair bundle 3 to the attachment base wire 2 with adhesive 5 and then wrapping the wound elastic wire 4 around it. After the hair bundle 3 is wound around the base wire 2, the base end of the wound elastic wire 4 is cut off. This base end may be tied to the tip or adhered to the wound portion with adhesive or the like.
  • the wrapped elastic wire 4 is wrapped around the tip of the hair bundle 3 (mainly the part bound with adhesive 5). At this time, care is taken to ensure that no gaps are formed between the wrapped elastic wire 4 wrapped around the (first) hair bundle 3 and the wrapped elastic wire 4 wrapped around the (second) hair bundle 3 (second winding process). In other words, the wrapped elastic wires 4 are wrapped so that they come into contact with each other.
  • the (third) hair bundle 3 is attached above the tip of the wrapped hair bundle 3 and tied (temporarily fastened) to the base wire 2, and then, as shown in Figure 3(d), the wrapping elastic wire 4 is wrapped around the tip of the hair bundle 3 (mainly the part bound with adhesive 5). At this time, care is taken to ensure that no gaps are formed between the wrapping elastic wire 4 wrapped around the (second) hair bundle 3 and the wrapping elastic wire 4 wrapped around the (third) hair bundle 3 (finished product: third winding process). Through these processes, the hair extension 1 is produced (see Figure 3(d)).
  • the natural hairs H, H... inserted through the first loop Ra and the second loop Rb are grasped with an extremely strong binding force.
  • the hair bundle 3 (and adhesive 5) has its tip cut to form a row of multiple semicircles (see Figure 2(b)).
  • the tip of the hair bundle 3 changes from a rectangular parallelepiped shape to a semicylindrical shape when bundled, reducing its bulk (volume) and making it less lumpy. Therefore, it can be worn without feeling lumpy to the touch (i.e., without the sensation of touching a lump that is different from hair) and with a natural appearance.
  • first loop 15a and second loop 15b positioned a predetermined distance apart, each fasten different parts of the natural hair H, H..., providing a high degree of restraint on the natural hair H, H..., allowing the device to remain attached for extended periods of time.
  • attachment base wire 2 which is the means for attaching the device to the hair, can be cut to become very compact after attachment, so the user will not feel uncomfortable even when lying down with the device attached.
