Description

  The present invention relates to a hair brush in which a brush body is connected to a grip portion.

  Hair brushes are used not only for combing hair, but also for straight perms for correcting curly hair of hair as straight as possible, and various proposals have been made (for example, Patent Document 1).

JP 2006-102363 A

  The hair brush proposed in the above-mentioned patent publication connects two handles that can be grasped with one hand to a tweezers, and the two handles are gripped with one hand of a user during a straight permanent. This user applies a drug for straight perm to the curly hair, grips the two handles of the hair brush, sandwiches the curly hair with the brush, and holds the handle while holding the hair brush toward the tip of the hair. Move to apply tension to curly hair. With the tension applied in this way, the user holds the dryer with the other hand and applies warm air to the hair where the tension is applied.

  The straight perm using the tweezers-type hair brush described above has no problem with the perm's workmanship. However, the gripping situation of two tweezers-type handles affects the situation of pinching the curly hair with a brush and applying tension to the hair. The gripping action had to be continued throughout the permanent procedure. In particular, when a person who desires a straight perm performs a straight perm, the person who desires the perm performs the above-mentioned specific gripping operation with one hand of the person to apply tension to the person's own hair. On the other hand, since it is necessary to operate the dryer with the other hand, it is necessary to be careful in the gripping operation of the brush, and the improvement has been demanded.

  In view of the above-described problems, an object of the present invention is to provide a new hair brush capable of simplifying a brush operation when applying tension to hair.

  In order to achieve at least a part of the above object, the present invention adopts the following configuration.

[Apply: hair brush]
A hair brush with a brush body connected to the gripping part,
In the brush body, a first brush tooth row in which brush teeth are arranged in a comb-teeth shape along the longitudinal direction of the brush body at a first inter-tooth pitch capable of combing hair, and when combing hair, A second brush tooth row in which brush teeth are arranged in a row along the longitudinal direction so as to allow tensioning to the hair accompanying the hair combing operation by friction with the hair being combed,
The gist of the present invention is that the second brush teeth are arranged between the teeth of the first brush teeth arranged in parallel.

  When using the hair brush having the above-described configuration, the user performs a hair combing operation of holding the grip portion and moving the hair brush having the above-described configuration from the hair root side to the hair tip side. By this hair combing operation, the hair is combed by the first brush teeth row arranged in parallel on the brush body and the second brush teeth row between the tooth rows. Since the first brush teeth arranged in parallel are arranged in a comb-teeth shape along the longitudinal direction of the brush body at the first inter-tooth pitch that enables hair combing, the above-described hair combing operation is performed. As a result, the hair flow is adjusted.

  On the other hand, the second brush dentition between the dentitions of the first brush dentition can apply tension to the hair accompanying the hair combing operation by rubbing the brush teeth with the combed hair when combing the hair. Therefore, the hair combed by the second brush tooth row receives tension in accordance with the above-described hair combing operation. In this case, since the second brush dentition is located between the dentitions of the first brush dentition, the hair flow is adjusted to the hair as described above in the first brush dentition, and the second brush dentition is arranged. Tension can be applied. The tensioned hair is stretched almost straight. The hair brush having the above-described configuration does not require a specific gripping operation in which tension is applied to the hair only by a user's hair combing operation, and the handle is gripped so that the two handles are not separated when the tension is applied. . In addition, if the user interrupts the hair combing operation halfway and holds the hair brush in the position where the brushing operation is interrupted, the hair brush having the above-described configuration is applied to the hair by the second brush dentition based on friction with the hair. Leave tension applied. As a result, according to the hair brush configured as described above, it is possible to easily apply tension to the hair only by combing the hair brush so that the grip portion is simply gripped and moving the hair brush from the root side to the tip side of the hair. can do. This also means that a hair brush suitable for a straight perm of curly hair can be provided.

  The above-described hair brush can be in the following mode. For example, the brush teeth of the second brush tooth row can be made shorter than the brush teeth of the first brush tooth row. If it carries out like this, hair will be combed by the 1st brush dentition with a long brush tooth first, and then it will be combed by the 2nd brush dentition with a short brush tooth. Therefore, the application of tension by the second brush tooth row to the hair whose hair flow is arranged in the first brush tooth row is ensured, and it is suitable for straightening and holding the curly hair during the straight perm of the curly hair. Become.

  As described above, when the length of the brush teeth is long and short in the first and second brush teeth rows, the first brush teeth row is the hair already described in the brush tooth portion longer than the brush teeth of the second brush teeth row. Necessarily causes the hair flow to be adjusted with the whispering movement. Therefore, in the 1st brush dentition, it is the same length as the brush teeth of the 2nd brush dentition, or shorter than this, between the brush teeth arranged in the pitch between the 1st teeth in which hair can be combed. The brush teeth can be added. In this way, in the first brush teeth, the brush teeth originally provided and the additional brush teeth are arranged in a comb-teeth array at a short pitch. Therefore, in the range extending over the length of the additional brush teeth, the plush tooth at a short pitch is used. It is also possible to apply tension to the hair. Therefore, the effectiveness of applying tension to the hair can be enhanced.

  The second brush tooth row may be a plurality of parallel brush tooth rows adjacent to each other between the tooth rows of the first brush tooth row. If it carries out like this, the effectiveness of tension | tensile_strength to hair can be improved more by the increase in a brush tooth row | line | column.

  And about the 2nd brush tooth row constituted by a plurality of parallel brush tooth rows in this way, this 2nd brush tooth row is made into the 2nd tooth narrower than the 1st inter-tooth pitch in each of the above-mentioned parallel brush tooth rows. The brush teeth can be arranged in a comb-teeth shape at a pitch, or the brush teeth can be arranged alternately in the adjacent parallel brush tooth row. If it carries out like this, in the 2nd brush tooth row | line | column as an adjacent parallel brush tooth row | line | column, since the interdental pitch will be narrow and a comb will be combed by the said 2nd interdental pitch. Either or both of the row of brush teeth and the staggered brush teeth can increase the effectiveness of applying tension by friction with the hair.

  In this case, the brush body includes the first brush tooth row in multiple rows in the curved brush tooth row setting portion, and the second brush tooth row between the adjacent tooth rows of the first brush tooth row. it can. In this way, when the brush body is viewed from the row direction of the brush teeth row, the multiple rows of the first brush teeth row and the second brush tooth row therebetween are arched in accordance with the brush row arrangement portion. Will be lined up. Therefore, when the user holds the hair brush at the position where the hair combing operation is interrupted, the user rotates the hair brush so that the hair is combed by the respective second brush teeth in the arch locus range. The tension can be easily applied to the hair.

  Thus, in the said 1st brush tooth row | line | column provided in multiple rows | lines, the said brush teeth can also be made to be alternately provided in the said 1st inter-tooth pitch in the row | line | column adjacent to it. If it carries out like this, it can contribute to alignment of the hair flow in the case of hair combing by the 1st brush dentition of multiple rows.

  Further, in making the second brush tooth row into a plurality of adjacent parallel brush tooth rows, each of the parallel brush tooth rows constituting the second brush tooth row is a hair bundle in which a large number of hairs are bundled. It can be set as the flocking brush row arranged in a line. If it carries out like this, since hair will be combed by each hair | bristle bundle of the parallel brush tooth row | line | column of several rows, tension can be given to hair by friction with the hair in each hair bundle.

  In the hair brush of each aspect described above, an edge side brush tooth row is provided on both side edges of the brush tooth row setting portion of the first and second brush tooth rows in the brush body. The edge-side brush dentition can be arranged in a comb-teeth shape along the longitudinal direction at an interdental pitch that allows tension to be applied to the hair as the hair combs by friction with the hair. . By so doing, tension can be applied to the hair by friction with the hair even by this edge side brush dentition due to the rotation of the hair brush, so that it is easy to apply tension to the hair and maintain the tension.

  Further, the edge side brush tooth rows located at both ends of the brush tooth row setting portion may be provided with the brush teeth facing outward so that the base portions of the brush teeth are back to back. By doing so, the brush teeth on both ends of the brush teeth arrangement section are arranged with the 180-degree opening of the brush teeth, so that the rotation operation of the hair brush described above for applying tension to the hair and maintaining the tension is performed. The range of use of the hairbrush can be expanded, and the usage of the hair brush can be diversified.

  Moreover, the site | part containing the brush dentition installation part in the said brush main body in which the said 1st, 2nd brush dentition was installed can also be made removable with respect to the said holding part. In this way, when a drug for hair treatment, for example, a drug for straight perm, adheres to the brush teeth, or the drug hardens between the brush teeth of the second brush dentition, the above part is attached and detached. Replacing makes it easy to deal with reuse.

  In addition, the arrangement side of the first and second brush tooth rows is the front surface of the main body, and the brush teeth are arranged on the back of the main body on the back side of the front surface of the main body at a pitch that allows hair to be combed. Can be provided with back brush portions arranged in multiple rows in a comb-teeth shape. In this way, hair brushing can be performed without excess or deficiency at the back brush part before or after the hair treatment using the brush teeth on the front surface of the main body, for example, or after the hair treatment.

  And this back brush part can also be equipped with the said brush tooth which can hold | maintain the chemical | medical agent for hair treatment, and can apply | coat the said chemical | medical agent to the hair accompanying the hair combing operation | movement. In this way, it is possible to apply the medicine to the hair without using a hand. In this case, the back brush portion can be detachably attached to the brush body.

  The brush body 20 includes a first brush tooth row 30 and a second brush tooth row 40 in a curved brush tooth row setting portion 21, and a first edge side brush on the curved edge side of the brush tooth row setting portion 21. A tooth row 51 and a second edge side brush tooth row 52 are provided. The first brush teeth row 30 is formed on the curved portion of the brush tooth row setting portion 21 over four rows at an equal pitch along the curve, and each first brush tooth row 30 combs the brush teeth into the hair. Are arranged in a comb-teeth array along the longitudinal direction of the brush body at a first inter-tooth pitch P1. The arrangement of the first inter-tooth pitch P1 and the four first brush tooth rows 30 will be described later. As shown in FIG. 4, for the four first brush tooth rows 30, the first brush tooth rows 30 </ b> R <b> 1 to R <b> 2, the first brush tooth rows 30 </ b> L <b> 1 to L <b> 2 Called.

  The second brush tooth row 40 is disposed between the first brush tooth rows 30, and brushes the brush teeth at a second inter-tooth pitch P <b> 2 that is narrower than the first inter-tooth pitch P <b> 1 of the first brush tooth row 30. These are two parallel brush tooth rows arranged adjacent to each other in a comb tooth shape along the longitudinal direction of the main body. FIG. 5 is an explanatory diagram for explaining the state of the brush tooth arrangement of the first brush tooth row 30 and the second brush tooth row 40. In addition, in this FIG. 5, the mode of the brush tooth arrangement | sequence when it assumes that the curved brush tooth row | line | column installation part 21 was extended in flat form is shown.

  As shown in FIG. 5, two rows of the first parallel brush tooth row 41 and the second parallel brush tooth row 42 arranged side by side so as to constitute the second brush tooth row 40 are in each brush tooth row. The brush teeth are arranged in a comb-teeth shape along the longitudinal direction of the brush body at the second inter-tooth pitch P2, and the brush teeth are provided alternately. For this reason, the 2nd brush tooth row | line 40 comprised by the 2nd 1st parallel brush tooth row | line | column 41 and the 2nd parallel brush tooth row | line | column 42 which were located next to each other is brushed with a half pitch of the second inter-tooth pitch P2. Teeth will be provided in a staggered pattern. In this embodiment, the second inter-tooth pitch P2 is about 2 mm. As shown in FIG. 4, the brush teeth of the second brush tooth row 40 are shorter than the brush teeth of the first brush tooth row 30. In the present embodiment, the brush tooth length of the second brush tooth row 40 is about 12 mm, which is approximately 80% of the brush tooth length of the first brush tooth row 30. About the brush tooth shape of the 2nd brush tooth row | line 40, although it was set as the triangular pyramid shape by planar view as shown in FIG. 5 in a present Example, it can also be made into a cone shape or flat plate shape.

  Further, as apparent from FIG. 5, each first brush tooth row 30 arranges brush teeth in a row at the first inter-tooth pitch P <b> 1, and specifically, in the adjacent row, the first brush tooth row. In the row 30L1 and the first brush tooth row 30L2, the brush teeth are alternately provided at the first inter-tooth pitch P1. The same applies to the first brush tooth row 30R1 and the first brush tooth row 30R2. As for the first brush tooth row 30L1 and the first brush tooth row 30R1, the brush teeth may be alternately provided at the first inter-tooth pitch P1. The first inter-tooth pitch P1 of the first brush tooth row 30 is a brush tooth interval at which hair can be combed as described above, and is not different from an existing hair brush for combing hair. In this embodiment, About 4 mm. In addition, this 1st interdental pitch P1 is suitably set in the range which can be practically used as a brush tooth space | interval which can comb the hair. Also, as shown in FIG. 4, the first brush tooth row 40 between the first brush tooth row 30 </ b> L <b> 1 and the first brush tooth row 30 </ b> R <b> 1 is positioned on the top of the curved portion of the brush tooth row setting portion 21. Although the tooth row 30L1 and the first brush tooth row 30R1 are arranged, the first brush tooth row 30 is arranged at an equal pitch after the first brush tooth row 30 is positioned on the top of the curved portion of the brush tooth row setting portion 21. It is also possible to arrange the second brush tooth row 40 between the rows.

  Here, the first inter-tooth pitch P1 and the second inter-tooth pitch P2 will be described with reference to the drawings. FIG. 6 is an explanatory diagram schematically showing the state of hair combing by the first brush tooth row 30 in which the brush teeth are arranged in a comb tooth row at the first inter-tooth pitch P1, and FIG. 7 is a brush at the second inter-tooth pitch P2. It is explanatory drawing which shows typically the mode of hair combing by the 2nd brush tooth row | line | column 40 which arranged the tooth | gear in zigzag form. As shown in FIG. 6, the first brush tooth row 30 having the first inter-tooth pitch P <b> 1 is an interval at which the hair can be combed, so that the hair brush 10 is moved from the hair root side to the hair tip side. Accommodates the hair flow of the hair (curly hair) as the moving hair moves. On the other hand, the second brush tooth row 40 having the second inter-tooth pitch P2 has a narrow pitch of about 2 mm, and the brush teeth of the first parallel brush tooth row 41 and the brush teeth of the second parallel brush tooth row 42 are arranged. Prepare in a staggered pattern alternately. Therefore, the second brush tooth row 40 includes a comb tooth-like brush tooth arrangement of both the first parallel brush tooth row 41 and the second parallel brush tooth row 42 at the second inter-tooth pitch P2 having a narrow interval. Due to the alternating arrangement of the brush teeth in the parallel brush teeth row, tension is applied to the hair due to friction with the hair (curly hair) during the hair combing in accordance with the above-described hair combing operation. Moreover, since the second brush teeth row 40 is located between the rows of the first brush teeth row 30, tension is applied to the hair (curly hair) whose hair flow is adjusted as described above in the first brush tooth row 30. Give.

  The first edge side brush tooth row 51 and the second edge side brush tooth row 52 located closer to the curved end edge than the first brush tooth row 30L2 and the first brush tooth row 30R2 are narrower than the first interdental pitch P1. Brush teeth are arranged in a row of comb teeth along the longitudinal direction of the brush body at intervals that allow tension to be applied to the hair by friction during hair combing. In the present embodiment, the brush tooth intervals of the first and second edge side brush tooth rows are set to be approximately the same as the second inter-tooth pitch P <b> 2 in the second brush tooth row 40. Further, as shown in FIG. 4, the left and right first edge side brush tooth rows 51 on the most curved edge side in FIGS. 1 and 4 are approximately 180 so that the bases of the brush teeth in each brush tooth row are back to back. Hold the brush teeth outward with an opening of °. Further, the left and right second edge side brush tooth rows 52 are positioned approximately in the middle between the first edge side brush tooth row 51 and the first brush tooth row 30L2, and the first edge side brush tooth row 51 and the first brush tooth row 30R2. So that the brush teeth are directed outward.

  In order to provide the brush body 20 with the first brush tooth row 30, the second brush tooth row 40, the first edge side brush tooth row 51 and the second edge side brush tooth row 52, as shown in FIG. After the brush tooth row is provided on the plate-like brush tooth placement sheet body 31, the brush tooth placement sheet body 31 may be placed along the curved brush tooth row placement portion 21. In addition, it is also possible to form each brush tooth row so as to protrude directly from the curved brush tooth row setting portion 21.

  Next, straight perm treatment of hair using the hair brush 10 of the above-described embodiment will be described. First, the person who desires a straight perm (user) attaches and holds the first permanent agent in the form of a cream or paste on his curly hair. The permanent agent is attached to the curly hair by moving the hand toward the tip of the curly hair after sandwiching the curly hair between the palm of one hand of the user carrying the first permanent agent and the palm of the other hand. Made. Alternatively, the first permanent agent can be attached to the curly hair by holding the first permanent agent on a dedicated brush for attaching the permanent agent and combing the curly hair with the brush. For curly hair near the scalp, the permanent agent is attached by pressing the palm carrying the first permanent agent against the scalp or bringing a dedicated brush into contact with the scalp.

  After attaching the first permanent agent, leave the permanent agent for a while so that it fits into curly hair, and then rinse the hair and make it semi-dry. As a result, the first permanent agent penetrates into the hair (curly hair), and the permeation of the permanent agent weakens the shape retention ability of the hair in a curly state. Thereafter, the user himself / herself uses the hair brush 10 to hang the straight permanent on his / her hair (curly hair). FIG. 8 is an explanatory view schematically showing the state of straight perm treatment by the person (user) who desires the straight perm, and FIG. 9 is an explanatory view schematically showing how the hair is combed during the straight perm treatment. is there.

  As shown in FIG. 8, the user simply grasps the grip portion 12 of the hair brush 10 with one hand so as to heat the hair (curly hair) that has penetrated the first permanent agent under tension. The hair brush 10 is moved from the root side of the hair to the end of the hair, and hot air is blown onto the hair (curly hair) from the dryer HD held by the other hand while holding the hair brush 10. The hair brush 10 adjusts the flow of hair (curly hair) as described above with the first brush tooth row 30 in accordance with the above-described hair combing operation, and then the hair (curly hair) with the second brush tooth row 40. ) Is tensioned so that the hair (curly hair) is stretched almost straight (see FIG. 9A). Moreover, the hair brush 10 can be used by the second brush teeth row 40 based on friction with the hair (curly hair) as long as the user interrupts the hair combing operation halfway and holds the brush at the position where the brushing operation is interrupted. A tension is applied to the hair (curly hair) to keep the hair (curly hair) stretched almost straight. For this reason, the user can whip the hair brush 10 grasped with one hand and keep it in the middle of the operation, and can easily blow warm air from the dryer HD onto the hair (curly hair) with the other hand. And since the hair (curly hair) that has penetrated the first permanent agent receives warm air in a state of being straightened, the ability to retain the shape of the curly hair is further weakened by the medicinal effect of the first permanent agent. It becomes the hair that is permed straight.

  After that, in order to maintain the straight form, a second permanent agent for restoring the hair shape retention power is sprinkled from the container onto the hair. The second permanent agent-attached hair is also allowed to stand for a while to wait for the second permanent agent to become familiar with the hair, and then rinsed and dried. As a result, the hair (curly hair) is fixed in a straight-perm state and straightened.

  As described above, when a user who desires a straight perm of curly hair performs a straight perm treatment using the hair brush 10 of this embodiment, the user himself performs a hair combing operation with the hair brush 10. Only by this, tension can be easily and reliably applied to hair (curly hair). Then, according to the hair brush 10 of the present embodiment, when applying the tension accompanying the user's own brush operation, the user can hold a unique grip such as holding two handles and maintaining the grip state. Do not force action. In addition, if the user interrupts the hair combing operation halfway and keeps the hair brush in the interrupting position of the combing operation, the hair brush 10 of the present embodiment is the second based on the friction with the hair (curly hair). The brush teeth row 40 keeps tension on the hair. Therefore, according to the hair brush 10 of the present embodiment, as shown in FIG. 8, the user performs a hair combing operation of the hair brush 10 by gripping the grip portion 12 with one hand simply. The warm air can be easily blown to the hair from the dryer HD held with the other hand. For this reason, the hair brush 10 of a present Example turns into a hair brush suitable for the straight perm by the user who desires the straight perm of curly hair.

  Further, in the hair brush 10 of the present embodiment, as shown in FIG. 4, the brush teeth of the second brush tooth row 40 are shorter than the brush teeth of the first brush tooth row 30. The hair (curly hair) that has been reliably struck first in the row 30 and whose hair flow has been adjusted can be combed with the second brush tooth row 40 having short brush teeth. For this reason, the tension imparted by the second brush tooth row 40 to the hair whose hair flow is adjusted by the first brush tooth row 30 and the maintenance of the straight shape of the hair associated therewith are ensured, and the straight hair It is suitable for straightening and maintaining curly hair during perm.

  Moreover, in the hair brush 10 of a present Example, as shown in FIG. 5, the 1st brush tooth row | line 30L1 and the 1st brush tooth row | line | column 30L2 which adjoin in the 1st brush tooth row | line | column 30, and 1st brush tooth row | line | column 30R1 and 1st In one brush tooth row 30R2, the brush teeth are alternately provided at the first inter-tooth pitch P1. For this reason, it is possible to enhance the alignment of the hair flow at the time of hair combing by the adjacent first brush tooth row 30L1 and the first brush tooth row 30L2, and the first brush tooth row 30R1 and the first brush tooth row 30R2. preferable.

  Moreover, in the hair brush 10 of a present Example, as shown in FIG. 4, the brush tooth row | line | column installation part 21 of the brush main body 20 is curved, and the 1st brush tooth row | line | column 30 and the 2nd brush tooth row | line | column 40 in the curved part. Therefore, the multi-row first brush tooth row 30 and the second brush tooth row 40 therebetween can be formed into an arched brush tooth row that follows the curvature of the brush tooth row setting portion 21. Therefore, when the user holds the hair brush 10 at the position where the hair combing operation is interrupted, the user rotates the hair brush (see FIG. 9B), so that the hairs in the range of the arch trajectory range. Since it is combed by the two brush tooth row 40, tension can be easily applied to the hair. In other words, the effectiveness of straight perm in straight perm treatment is increased.

  In addition, the hair brush 10 of the present embodiment includes the first edge side brush tooth row 51 and the second edge side brush tooth row 52 on the curved edge side of the curved brush tooth placement portion 21, and the both brush teeth. The rows were narrower than the first inter-tooth pitch P1, and the brush teeth were arranged in rows at intervals at which tension can be applied to the hair by friction during hair combing. For this reason, when the hair brush 10 is rotated as described above (see FIG. 9B), the first edge side brush tooth row 51 and the second edge side brush tooth row 52 also cause friction with the hair. Since tension can be applied to the hair, tensioning and maintaining the tension on the hair are facilitated.

  Furthermore, the 1st edge side brush tooth row | line | column 51 located in the both ends of the curved brush tooth row | line | column installation part 21 shall be equipped with a brush tooth facing outward so that the base part of a brush tooth may become back-to-back. For this reason, the brush left and right first edge side brush tooth rows 51 at both ends of the curved brush tooth row installation portion are arranged with a 180-degree opening, so that tension is applied to the hair and the tension is maintained.
