DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to hairdressing scissors, especially combing scissors.

[0002]

2. Description of the Related Art In general, as scissors used in the field of beauty and beauty, there are known card scissors in which a comb-shaped comb blade and a normal cutting blade are pivotably connected.

[0003] Conventionally, this scissors cut hair held between the tip of each tooth constituting the comb blade and the cutting blade, and the other hair is broken between the teeth and not cut. In order to escape from the gap between the teeth.

However, in the case of the above-mentioned conventional carding scissors, since only one groove is formed at the tip of each tooth of the carding blade, the hair is cut into a ring shape between the tip of each tooth and the cutting blade. Had been made. Therefore, when the hair cut into such a shape is mixed with the hair that has not been cut at all, it is difficult for the hair to be entangled with the hair that has not been cut. As a result, the hair that has been cut and shortened is more likely to fluff, resulting in an inconvenience that the cut set cannot be finished well.

For this reason, the present inventor has disclosed in Japanese Patent Application No. Hei 6-136784 that the number of grooves is two (two cards) and that the number of grooves is four.
Japanese Patent Application No. 6-236485 of this book (four cards) and Japanese Patent Application No. 6-269637 of three cards (three cards) were invented.

[0006]

These applications can solve the problems of the conventional card blade, in which the hair becomes easy to fluff and the set after cutting is not finished well. The same number of grooves were formed at the tips of the teeth. For this reason, the hair is combed by the same amount in the groove at the tip of both the root part, the blade tip part and the middle part of the comb blade, and the strength of compressing the hair with the card blade and the cutting blade is greater at the root part. The combing resistance of the hair at the root of the blade is greater than at the cutting edge and middle of the comb.

As an advanced technique, a user engages a combing blade and a cutting blade to cut the scissors while moving the cutting scissors around the root of the combing scissors so as to draw a circle, and to comb the scissors. Cutting is performed by moving the blade and cutting blade in parallel while meshing.

In the above-mentioned application, since the root portion and the cutting edge portion of the card blade have the same number of grooves, the card scissors are moved around the root of the card blade while the card blade and the cutting blade are engaged with each other. Since the combing resistance is high, the hair is easily clogged by being caught in the groove. So, when you remove the scissors from the hair, you will pull this hair,
There is an inconvenience that the feeling of use is poor for both the user and the person who can cut the hair.

Further, if the carding scissors are moved in parallel with the carding blade and the cutting blade engaged with each other, since the carding resistance of the base part becomes larger than that of the blade edge part, the hair is pulled and stretched at the base of the carding scissors, and cut. The blade edge and the intermediate portion are cut without being pulled. Therefore, the position of the hair to be cut differs between the blade tip and the middle part and the root part of the carding scissors, and there is an inconvenience that the hair cannot be cut as desired by the user.

[0010] The present invention solves the problem that the conventional hair is easily fluffed and the set after cutting is not finished well, and at the same time, it is possible to cut as desired by the user by wiping out the above-mentioned inferior feeling of use. The purpose is to provide a carding scissors.

[0011]

Means for Solving the Problems In order to solve the above-mentioned problems, a carding scissor according to the present invention is provided with a cutting blade and a carding blade having comb-shaped teeth formed thereon so as to be rotatable. In addition, all the teeth are formed at equal intervals, and several grooves are respectively formed at the tips of the other teeth except for some of the teeth located on the root side of the card blade. While being formed along the thickness direction of the teeth, the tips of several teeth located on the root side of the card blade have a smaller number of grooves than the other teeth, and the root of the card blade is formed. The number of grooves is smaller for teeth closer to.

In the present invention, carding blade 2 of carding scissors 1
Of the teeth 20 constituting the tooth, the number of grooves 22 smaller than that of the other teeth 20 are formed at the tips of several teeth 201 located on the root side of the card blade 2, and at the root of the card blade 2. Since the number of the groove portions 22 is smaller as the teeth are closer, the amount of hair that enters the groove portions 22 of the root teeth 201 is smaller than that of the cutting edge portion and the intermediate portion. For this reason, the combing resistance of the hair is smaller than that of the cutting edge and the intermediate portion, and the hair at the root does not get caught in the groove 22 and is not clogged, and the hair at the root is not stretched and cut.

Therefore, the user engages the comb blade 2 and the cutting blade 3 to make the cutting edge portion 26,
Even if the scissors 1 are cut while moving the scissors 1 in a circular motion, the hair can be cut smoothly without clogging the hair at the root. Therefore, when the comb scissors are released from the hair, the hair is not pulled and the feeling of use is improved for both the user and the person who can cut the hair.

When the carding scissors are moved in parallel with the carding blade and the cutting blade engaged with each other, the carding resistance of the root portion becomes smaller than that of the blade edge portion and the intermediate portion. Therefore, it is possible to avoid a phenomenon in which the comb scissors are moved and the hair is pulled together with the movement of the scissors by an amount corresponding to the large combing resistance. Therefore, the cutting at the root portion of the comb scissors and the cutting at the cutting edge portion and the intermediate portion are performed at substantially the same position of the hair, so that the user can cut as desired.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a carding scissor according to the present invention.

FIG. 1 schematically shows the entire structure of the carding scissors, FIG. 2 shows carding blades at the root of the carding scissors, (A) for carding, and (B) for carding. (C) is for four carding. FIG. 3 is a partial cross-sectional view showing a spindle portion of the carding scissors.

The comb scissors 1 have a comb blade 2 and a cutting blade 3 rotatably connected to each other.
2 is formed in the shape as shown in FIG. 2, and two, three, and four grooves 22 are formed in the front end 21 along the thickness direction of the teeth.

Of the teeth 20 constituting the comb blade 2, the grooves 22 of several teeth 201 located on the root side are arranged. If the number of grooves in other teeth is two, one is three. Are two in sequence,
In the case of four, the number is similarly reduced to three, two, and one in the same manner.

The carding blade 2 and the cutting blade 3 have recesses 24 and 34 formed on opposing joint surfaces 23 and 33, respectively. Then, in a state of being sandwiched between the concave portions 24 and 34, a radial ball bearing 4 having a shield plate or a sealing plate 5 interposed on both sides between the inner ring 41 and the outer ring 42 is provided. It is adapted to be pivotally connected with a set screw 7.

The recesses 24, 34 formed in the joining surfaces 23, 33 between the carding blade 2 and the cutting blade 3 are circular,
The depth is the gripping portion 25 of the carding blade 2 and the cutting blade 3, respectively.
It is formed so that it gradually becomes deeper from 35 toward the cutting edge portions 26 and 36.

A conical shaft hole 37 is formed in the center of the recess 34, and a square shaft hole 27 is formed in the center of the recess 24.

The shaft pin 6 is formed by connecting a shaft portion 62, a square shaft portion 63 and a screw shaft portion 64 continuously from the base end of a conical head 61. Is a washer 65
A holding groove 66 is provided around the holding groove 66. By fitting and holding the washer 65 in the holding groove portion 66, the washer 65 can be easily assembled without being detached from the support pin 6 during assembly. .

The set screw 7 is adapted to be screwed to the screw shaft portion 64 of the support pin 6, and its outer peripheral surface is knurled so that the set screw 7 can be easily screwed with a finger. A non-slip portion 71 is formed. Also, in this screwed state, the set screw 7 which faces the head 61 of the support pin 6
A claw gear 72 is provided on the inner surface side of.

In the carding scissors 1 thus constructed, the head 61 of the spindle pin 6 is located in the spindle hole 37 of the cutting blade 3, the shaft 62 is located in the radial ball bearing 4, and the square shaft 63 The shaft pin 6 is inserted in the order of the cutting blade 3, the radial ball bearing 4, and the comb blade 2 so that is positioned in the shaft hole 27 of the comb blade 2.
Then, it is assembled by screwing a set screw 7 to a screw shaft portion 64 protruding outside the comb blade 2 via an arc-shaped leaf spring 8.

The arc-shaped leaf spring 8 is provided with an insertion hole 81 through which the pivot pin 6 is inserted.
2 are protruded, and are inserted and locked in locking holes 28 provided outside the card blade 2. Then, the arc-shaped leaf spring 8 warped in an arc shape is gradually extended into a plate shape by the screwing of the set screw 7, and the concave portions 24 and 34 which sandwich the radial ball bearing 4 from both sides are formed by the elasticity generated at this time. The rotational resistance between the joint surface 23 of the carding blade 2 and the joint surface 33 of the cutting blade 3 is determined via. That is, the set screw 7
Are firmly screwed together so that the elastic force of the arcuate leaf spring 8 acts strongly, so that the rotation of the cutting blade 3 with respect to the comb blade 2 becomes heavy. Further, by loosely screwing the set screw 7 so that the elastic force of the arcuate leaf spring 8 acts weakly, the rotation of the cutting blade 3 with respect to the comb blade 2 becomes light. The adjustment of the rotation resistance can be easily performed by appropriately adjusting the screwing state of the set screw 7 according to the user's preference.

At this time, a projection 83 is protruded from the arc-shaped leaf spring 8 so that the set screw 7 thus adjusted is not loosened. The projection 83 is engaged with the claw gear 72 of the set screw 7. I have. As a result, the set screw 7 rotates intermittently.

Further, as shown in FIG.
In the vicinity of the insertion hole 81, two reinforcing portions 84 which become uneven in the thickness direction may be formed. In this case, the arc-shaped leaf spring 8
Since the elastic force of the set screw 7 is increased in the vicinity of the insertion hole 81, when the set screw 7 is screwed, the meshing state between the claw gear 72 of the set screw 7 and the projection 83 changes to the screwed state of the set screw 7. Irrespective of this, it becomes stable and the adjustment of the rotation resistance can be performed comfortably.

As described above, the feeling of using the card scissors 1 is as follows.
The radial ball bearing 4 fitted between the concave portion 24 of the comb blade 2 and the concave portion 34 of the cutting blade 3 depending on how the set screw 7 is screwed.
It is determined by adjusting the mutual rotational resistance between the two.

The carding scissors 1 constructed as described above
Are concave portions 24 and 34 formed in the carding blade 2 and the cutting blade 3.
Are formed so as to become gradually deeper from the gripping portions 25 and 35 toward the cutting edge portions 26 and 36, respectively. Therefore, when the carding scissors 1 are closed from the open state, the concave portions 24 and 34 are formed. The state shifts from a state where the shallow part and the deep part face each other to a state where the shallow part and the deep part face each other. Therefore, as shown in FIG.
When the comb scissors 1 are closed, the radial ball bearings 4 in the shallow portions of the holding portions 25 and 35 of the concave portions 24 and 34 are pinched with a strong pinching force. As a result, the gripper 2
5 and 35, a force acts in a direction in which the interval is widened, and a force is applied to the cutting edge portions 26 and 36 in a direction closer to each other, so that the cutting edge portions 26 and 36 are properly fitted to each other. Has been made.

As described above, in the carding scissors 1, the holding interval between the concave portions 24 and 34 changes according to the open or closed use state.
There is a concern that the intrusion may occur between 34. However, in the case of the carding scissors 1, as shown in FIG. 5, since a shield plate or a sealing plate 5 is provided between the inner ring 41 and the outer ring 42 on both sides of the radial ball bearing 4, chips or the like are used. Can be completely prevented. As a result, there is no case where chips or the like bite into the radial ball bearing 4 to deteriorate the turning state, and a smooth turning state can be maintained for a long period of time.

In this embodiment, two to four grooves 22 are provided at the tip 21 of each tooth 20 of the card blade 2. However, the number of the grooves 22 is limited to two to four. Instead, five or more may be used.

[0032]

The carding scissors of the present invention are carding scissors in which a cutting blade and a carded tooth having comb-shaped teeth are rotatably connected to each other, and the teeth are all spaced at equal intervals. At the same time, several grooves are formed along the thickness direction of each tooth at the tip of each tooth other than the teeth located at the root side of the card blade. At the tips of several teeth located on the root side of the card blade, a smaller number of grooves were formed than the other teeth, and the number of grooves was smaller as the teeth were closer to the root of the card blade. Therefore, the combing resistance of the hair at the root portion is smaller than that at the cutting edge portion and the middle portion of the carding scissors.

Thus, as an advanced technique, even if the user moves the cutting scissors such that the cutting edge portion draws a circle around the root of the combing scissors by engaging the combing blade and the cutting blade and cuts the scissors, There is no clogging of the hair, and the feeling of use is improved for both users and those who have their hair cut.

Further, even if the scissors are cut by moving the scissors in parallel with the combing blade and the cutting blade engaged with each other, the cutting at the root of the combing scissors and the cutting at the cutting edge portion and the intermediate portion are performed on the hair. Since the cutting is performed at substantially the same position, cutting can be performed as desired by the user.
