Abstract

The present invention relates to a hair extension assembly which is formed by cohering the both ends of a connection ring to the upper tip of a hair extension where multiple strands of hair are fixed with an adhesive, upwardly inserting a separate auxiliary ring comprising a ring and a handle into the connection ring which is integrated with a string by binding the cohered region with the string for preventing the separation of the connection ring, and inserting various shapes of a contractible tube or compressive ring into the auxiliary ring; and a connection and disconnection method of the hair extension using the same. Hair loss in the hair extension is prevented by cohering the upper tip of the hair extension with the connection ring and by firmly binding the upper portion with the string, and the untying of the hair of a user wound to the connection region is prevented by winding the outer circumference surface of the connection ring of the hair extension with the hair of a user numerous times and by covering the upper portion with the contractible tube or compressive ring to fix the same through compression by the contraction of the tube or through compression of the compressive ring so as to remarkably improve the binding force of the hair extension with the hair of a user, thereby preventing the hair extension from moving downward or falling out even if a physical tensile force is applied by prolonged use, external pressure or an increase in the oil of the hair. The hair extension can be easily and simply disconnected by pushing the tube of the connection region or loosening the compression of the compressive ring and by pulling the hair extension away from the hair of a user when the hair extension is disconnected from the hair of a user without any damage since chemicals and the like are not used. The present invention enables operation through a very simple method and ultimately allows anyone, regardless of whether the user is an expert or a non-expert, to smoothly carry out operation thereof, and thus the work process is simplified and working time is reduced, and the reuse of the disconnected hair extension due to the connection method through the hair extension assembly is economical.

Description

Joint hair assembly and joint hair connection and disconnection method using the same

The present invention relates to a joint assembly of the user's hair and the method of connecting and disconnecting the joint hair using the same in order to produce a variety of hairstyles, such as lengthening the user's hair length or thinning the hair, more specifically, After attaching both ends of the linking ring to the top tip of the jointed hair to which a plurality of hairs are fixed with an adhesive, attach a separate auxiliary ring consisting of a hook and a handle to the linking ring integrated by tying the parts together so that the linking ring is not separated. After inserting in the upward direction, the back of the joint ring assembly of the various types of tube or crimping ring having a shrinkage is inserted into the ring of the secondary ring and a method of connecting and disconnecting the joint hair using the same.

Changes in the times require different styles of hair, regardless of gender, especially the use of joint hair techniques to lengthen or thicken hair, or simply apply or apply it to change color or shape. It is a common phenomenon to use a means to produce unique personalities, and the demand is exploding all over the world.

In the manufacture of such a joint hair, human hair or artificial hair is generally used. A hot air balloon melts an adhesive to make a tip on the top of the joint hair, and then the tip is placed on the user's hair and the hot air balloon melts the adhesive of the tip. Various techniques are used, such as connecting to a ring, inserting a ring into a user's hair and inserting a tip into the ring, pressing it with a forceps, attaching it to a tape type hair using adhesive tape, or applying an adhesive.

The pores used in these techniques are mainly used for heat gluer, knitting needle or hook, fryer, etc. Of course, problems such as damage to the scalp have been raised, and moreover, there is a problem in that hair loss occurs and flows due to weakening of adhesive strength due to changes in physical properties such as corrosion of the adhesive during use of the joint hair.

When the joint hair is terminated, it is necessary to use flammable chemicals to dissolve the adhesive or to use a hot air balloon or a pore tool, and thus there is a problem that the above-mentioned risk cannot be excluded and the damage of the hair can not be avoided.

Therefore, in order to solve the above problems, the applicant of the present invention is a user's hair in a state in which a certain amount of joint hair is bonded to the inner surface such as a hair connection shrinkage tube or a connection ring as Utility Model Registration Nos. 316019 and 333865. After penetrating through the inside of the connection shrinkage tube or the connection ring, the outside of the hair connection shrinkage tube is heated to shrink and at the same time melt the pressure-sensitive adhesive inside the hair connection method and press the connection ring and the user hair and the joint A joint hair connection method is proposed, in which hairs are connected and fixed to each other.

However, in the above case, the joint hair fused to the inner circumferential surface of the hair contraction tube or the connection ring is easily corroded due to the natural oxidation of the adhesive or the physical property change caused by the use of various detergent oils such as shampoo. When partial hair loss occurs due to oxidation and corrosion, hair loss progresses in series and the entire joint hair is hair loss. In addition, it is pointed out that the inside of the connection part is loose and the hair connection shrinkage tube or the connection ring flows down so that it does not satisfy the function as a joint hair.

Therefore, the present invention has been made to solve the inherent problems such as hair loss and runoff caused by using only the adhesive or the joint hair connection work by simple compression, and the risks caused by using flammable chemicals. In order to prevent the separation between the user hair and the joint hair by prolonged use or external pressure by increasing the bonding force when the user hair and the joint hair are connected, the user hair is used by using a shrinking tube or a compression ring during the procedure. Simple operation to cover or squeeze the outer circumferential surface of the joint between the joint and the joint hair, so that any skilled or unskilled person can safely and reliably connect and disconnect the joint hair without damaging the user's hair. Joint hair assembly for shortening the time and Using the an object of the present invention to provide a connection with the termination of the method of coupling the hair.

In order to achieve the above object, the present invention, after bonding both ends of the connecting ring to the upper end of the joint of the plurality of hair fixed with a pressure-sensitive adhesive, the link ring is tied to the connection ring integrated so that the connection ring does not escape After inserting a separate auxiliary ring consisting of and the handle in the upper direction, it is characterized in that to provide a joint hair assembly consisting of a tube or crimping ring of various shapes having a shrinking back to the ring of the auxiliary ring.

The shape of the top end of the joint hair is formed by rounding or flattening to form a rounded joint when the rounded hair is formed, and when flattening, the jointed hair is flattened.

In addition, the connecting ring to be integrated to the upper end of the joint hair is characterized in that the shape starts from the center of the tip and ends at the center of the tip or the shape starting from one side of the tip and ends at the other side.

In addition, the tube is a single-cell, elliptical, hat-shaped, "

","

It is characterized by the shape.

In addition, the tube is characterized in that the tube having a heat shrink by the tube having a self-retracting force or heat.

In addition, the auxiliary ring is "

","

""

","

" or "

"Is any one of the shape.

On the other hand, the method of connecting the user hair and the joint hair using each component of the joint hair assembly is as follows.

a) inserting a certain amount of user hair to be connected to the joint hair into the loop of the secondary ring of the joint hair assembly,

b) pulling the handle of the auxiliary ring of step a) and inserting the user's hair into the connecting ring through the inner surface of the tube or crimping ring fitted to the ring of the auxiliary ring,

c) rotating the joint hair so that the user hair inserted into the connecting ring of step b) wraps around the outer circumferential surface of the connecting ring, or winding the user's hair several times; and

d) pulling the tube or the compression ring through which the user hair of step b) penetrates to the lower side and covering the connection part wound on the outer circumferential surface of the connecting ring .

Here, when the shape of the top tip of the joint hair is rounded, the joint is rotated to wind the hair, and when the shape of the top tip of the joint hair is formed flat, there is a difficulty of winding the user hair by rotating the joint hair. It is desirable to wind the hair several times.

On the other hand, in the case of using the pressing ring is characterized in that it further comprises the step of pressing the overlapped pressing ring of step d) after the step d).

In addition, the method of canceling the user hair connected to the joint hair is as follows.

a) pushing up the tube or pressing ring, which is overlaid on the connection part where the user's hair is wound;

b) pulling the joint hair from the user hair of step a).

On the other hand, in the case of using a crimping ring, the step of releasing the crimping to return to the original state before the crimped ring is further characterized in that it further comprises before step a).

As described above, the present invention is to prevent the hair loss phenomenon of the joint hair by bonding the upper tip of the joint hair with an adhesive together with the adhesive and tightly tied with a string, and wraps the outer circumferential surface of the joint hair joint with the user hair Wrap several times and cover the tube or crimping ring without using a separate hot air balloon, and compress and fix the crimping or crimping ring due to the contraction of the tube to prevent the user's hair from being wound around the connection part. Since the bonding force between the joint hair and the user's hair is greatly strengthened, there is an effect that the joint hair does not flow down or fall off even if the physical tension is applied or the oil of the hair is increased by prolonged use or external pressure.

In addition, even when the joint hair is released from the user's hair, it is necessary to push out the tube of the connection part or to uncompress the pressing ring and release the wound user's hair, and then pull the joint hair to use hot air or chemicals. It is effective to terminate easily and without any damage.

Therefore, the present invention is ultimately possible to perform the operation in a very simple way that any skilled or inexperienced person can perform the operation smoothly, thereby bringing the effect of simplifying the work process and shortening the working time. The terminated joint hair is economical because it can be reused by the connection method through the joint hair assembly.

The method of connecting the joint hair to the user's hair by using the present invention hair joint assembly 1 according to the above structure and the method of releasing the connection will be described in detail with reference to the accompanying drawings.

First, as shown in FIGS. 1 and 2, both ends of the connecting ring 4 are attached to the tip 3 to which the plurality of strands of the hair 2 are rounded together or flattened and fixed. The connecting ring 4 is more securely fixed to the connecting ring 4 by tying together a portion of the tip 3 with a string so as not to be separated from the tip 3, and connecting the connecting hair 2 and the tip 3 to the tip 3. Together with the ring 4 is provided a joint connection ring tied.

This joint connection may be that the joint hair (2) adhered to the tip (3), it is also possible to use the shrinkage by covering the tube (3a) on the outside of the tip (3) to which the joint hair (2) is attached. Of course.

The connection ring 4 is a state in which a separate auxiliary ring 7 composed of a ring 7a and a handle 7b is fitted upward. That is, the auxiliary ring (7) to the tube 6 or the pressing ring (8) of various shapes having shrinkage in a state that the lower handle (7b) is fitted from the upper ring (7a) direction to be caught by the connecting ring (4) Through the ring (7a) of the joint to form the hair assembly (1).

As described above, the jointing of the upper end of the joint hair tip 3 with the adhesive 4 together with the adhesive and tightly tied with a string on the top strengthens the binding of the tip 3 and the corrosion of the adhesive painted on the tip 3. This is to prevent the hair loss phenomenon of the joint hair (2) in advance.

In addition, the tube (3a) is covered on the tip (3) to strengthen the binding of the tip (3) like a string, as well as to prevent corrosion and hair loss phenomenon.

In order to connect to the user hair 5 to connect the joint hair using the joint hair assembly 1 as described above, first, as shown in FIGS. 3 and 9, a certain amount of the user wants to connect the joint hair 2. The hair 5 is inserted into the ring 7a of the secondary ring 7 of the joint hair assembly 1.

In this state, as shown in Figs. 4 and 10, the puller 7b of the auxiliary ring 7 pulls the user's hair 5 into the ring 6a of the ring 7a of the auxiliary ring 7, or The inner ring of the crimping ring 8 is inserted into the connecting ring 4.

In this state, as shown in FIGS. 5 and 11, when the shape of the tip 3 is round, the user hair 5 fitted to the connecting ring 4 is wrapped around the outer circumferential surface of the connecting ring 4. After the joint hair (2) is rotated to be wound several times.

On the other hand, as shown in Figs. 7 and 14, in the case of the flat shape of the tip 3, it is difficult to wind the user's hair by rotating the joint hair 2 to turn the user's hair 5 several times. It is desirable to wind up.

In this state, as shown in FIGS. 6 and 12, the user hair 5 is pulled downward by pulling the tube 6 or the compression ring 8 through which the user hair 5 is penetrated. When it is overlaid on the connecting portion wound on the outer circumferential surface of), it is press-fixed and fixed by the self-contracting force in the case of the tube 6 having self-shrinkable force, and in the case of the tube 6 having the heat-shrinkable force, it is fixed by the shrinking force by heat.

On the other hand, in the case of the crimping ring 8 as shown in FIG. 13, if the crimping tool is fixed by a crimping tool, the coupling force of the connecting portion is increased.

The tube 6 is a tube made of a material having excellent self-shrinkability, such as urethane and silicone, or a heat shrink tube made of thermoplastic resin such as polyvinyl chloride (PVC), polyethylene (PE), and heat shrinkable by heat. It is desirable to.

The pressing ring 8 is made of a non-ferrous metal such as aluminum, nickel, tin, copper, alloy, etc., and has a deformation force bent by artificial force of the operator, but almost no elasticity to maintain the deformed shape continuously It is preferable to select a material. In addition, the tube (6) and the compression ring (8) is suitable to have a size that is not easily exposed to the outside even in the state of completion of the treatment of the joint hair, material or surface layer of the same color as the actual color of the joint hair It may have a coating layer or a painting layer.

As a result, in view of the amount and position of the joint hair to be treated as shown in Figures 8 and 15, the appropriate number may be fixed.

As such, the outer circumferential surface of the joint hair connecting ring is wrapped with user hair and wound several times, and a self-contracting tube or a heat-shrinkable tube or a compression ring by the heat is covered thereon, thereby compressing or compressing the ring by the self-retraction force or the heat shrinkage force of the tube. By compressing and fixing, the user's hair wound on the connection part can be prevented from being loosened, and the bonding force between the joint hair and the user's hair is greatly strengthened, so that physical tension is applied for a long time or external pressure or the oil of the hair is increased. Even if the hair is falling or falling off the problem will be completely eliminated.

On the other hand, in order to terminate the joint hair from the user hair, as shown in FIG. 33, the tube 6, which is overlaid on the connection portion where the user hair 5 is wound, is pushed upward.

On the other hand, when the crimping ring 8 is used, the crimping of the crimping ring 8 is released as shown in FIG. 35, and then the crimping ring 8 returned to the state before the crimping as shown in FIG. 36 is pushed upward. give.
