The conceptual diagram which showed the quantity of the winding hair group after hair insertion of the hair shaping device of Example 1 (after mounting | wearing).

Hereinafter, the hair shaping device of the present invention will be described with reference to the drawings showing Example 1. FIG. The hair shaping device 1 of Example 1 of the present invention shown in FIGS.
A rod-shaped first spiral rod 2 spirally formed around a virtual axis in a predetermined circumferential direction;
It consists of a second spiral rod 3 spirally formed in a predetermined circumferential direction around the virtual axis that is the same as or parallel to the virtual axis at a non-contact proximity position with the first spiral rod.
One end of each spiral rod is opposed to each other and connected at a predetermined crossing angle 4θ to form a connecting tip portion 4, and the other end of each spiral rod is bent in a direction away from each other to form a separation end portion 6. By doing so, it is configured as an integral bent or curved rod.

And it is a hair shaping device which can stop the hair by twisting it into the user's hair with the bent connecting portion 4 as the head.
Each separated end portion is bent in the direction opposite to the spiral rotation direction in the cross-sectional view, and the first inner surface near each separated end portion and the first end connected to each separated end portion in the cross-sectional view. A radial displacement space (2D, 3D) is formed between each of the second spiral rods 2, 3 and the outer spiral outer surface. Due to this biased space (2D, 3D), it is excellent in operability at the time of torsional insertion and after insertion and fixing, and also excellent in fixing property in the hair of the forming device itself. Further, since it protrudes outward in the radial direction at the other end, it is easy to recognize the fixing position without visually observing with a mirror or the like, and the concealing work or hair shaping work with the surrounding hair is performed more efficiently.
(First and second spiral rods 2, 3)
The first and second spiral rods 2 and 3 are spirally formed in the same circumferential direction with the central portion excluding one end and the other end substantially corresponding to a half circumference in a cross-sectional view, ie, maintaining a phase difference of about 180 degrees. Is done.

  Each of them is made of a rigid rod-shaped body having a circular cross section, and its peripheral surface is covered with a synthetic resin layer made of a non-electrostatic material, and is spirally formed around the same linear virtual axis in a predetermined circumferential direction. The first and second spiral rods are spirally formed around a virtual axis in a predetermined circumferential direction at a position not in contact with the first spiral rod. The first and second spiral rods are integrally connected to each other at the connecting tip 4 at the tip, and have a space for winding the hair when a screw is inserted.

  The first and second spiral rods 2 and 3 also maintain a phase difference corresponding to substantially a half circumference in a cross-sectional view when the central portions except for one end (connection destination portion 4) and the other end (2E, 3E) thereof. Are spirally formed in the same circumferential direction. If this is the case, the first and second spiral rods 2 and 3 can be wound evenly in the circumferential direction by spiral progression with a phase difference of half a cycle, and excellent in straightness of torsional progression. Therefore, it is easy to perform the operation in the twisting direction, and it is possible to more reliably prevent a situation where the screwing is performed in a direction contrary to the intention.

  (Biased end portion 2E, 3E) Among the first and second spiral rods 2, 3, in a predetermined length portion at the other end connected to each separated end portion, outward from the spiral circumference closer to one end than the portion. Deflection end portions 2E and 3E that are curved in the same direction as the spiral rotation direction are formed at the deviated axial cross-sectional view outward deviating position.

  Each biased end 2E, 3E is configured in a rod length section within a half turn of the spiral from the other end connected to each separated end in an axial cross-sectional view, and at least each of the spiral rods radially outward It is biased with an amount of outward deflection equal to or greater than the bar width, and has a separation end 6 at the end. Each of the separating end portions 6 connected to the first and second spiral rods (2/3) is bent in the direction opposite to the spiral rotation direction of the spiral rod (2/3) in a cross-sectional view. Thus, a radial displacement space (2D, 3D) is provided between the inner side surface of each separation end portion 6 and the outer surface of the first and second spiral rods 2, 3 connected to each separation end portion 6, respectively. ) Is formed.

  The biased end portions 2E and 3E are also configured from the vicinity of the other end of the first and second spiral rods 2 and 3 to the other end connected to the separating end portion 6, and the spiral loop portion on one end side of the portion. It is helically curved around the same axis as the spiral rotation direction while being biased outward with respect to the axis rather than the rotation diameter. The biased end portions 2E and 3E expand in the coaxial spiral direction while expanding the diameter toward the other end, so that the other end portion has a spiral rod portion having a larger winding amount than the central spiral turn portion. As a result, the amount of curly hair 5E can be secured at the other end of the spiral bar more than the amount of curly hair 5 at the center, and the amount of winding on one spiral bar can be changed without giving an excessive burden on the hair. Based on the fixing property in the hair. In particular, each of the biased end portions 2E and 3E is configured in a rod length section having a spiral angle within a half spiral turn of the spiral turn portion connected to each separated end portion in the cross-sectional view, and radially outward. It is preferable that the deflection is made with at least the outer deflection amounts 2D and 3D equal to or larger than the width of each spiral rod.

In addition, the connection destination part 4 is composed of a bent part that is integrally formed by connecting each end of the first and second spiral rods 2 and 3 at an intersecting angle 4θ of 90 degrees or less, and at the top of the bent part. A substantially semi-elliptical bulged portion 7 bulged in a flat shape from at least one side of the connecting side surface to the outside in the axial direction is formed.

  By pressing the protruding portion 4P, which bulges forward from the spiral rods 2 and 3 near the tip, against the hair bundle, it can be reliably inserted without being displaced from the initial contact position into the hair bundle. it can.

  Further, the hollow portion 4D can secure a larger amount of winding hair than the central winding space 9 in the winding space 8 at the tip constituted by the first and second spiral rods 2 and 3. It is excellent in fixability in the hair based on the change in the amount of winding in one spiral bar. Further, the first and second spiral rods 2 and 3 are opposed so that the winding hair group 5T in the winding space 8 at the other end and the winding hair group 5E in the winding space 8 at the tip end have approximately the same amount. By adjusting the twisted area, hair winding is performed with the winding space 5 slightly reduced only at the center portion while keeping the amount of winding hair as a whole constant. In this case, the amount of curly hair 5T, 5E at both ends including the tip and the other end can be secured more than the plurality of curly hair amounts 5 at the center, and the winding on one spiral bar can be performed without giving an excessive burden on the hair. Excellent fixability in the hair based on the change in the amount.

  Further, it can be plunged with a relatively sharp tip shape at an intersection angle 4θ smaller than 90 degrees, and when the bent portion is pressed against the hair bundle, the hair bundle is pushed away by the bulging portion. It can be easily inserted without being displaced from the initial contact position into the hair bundle.

(how to use)
When using the hair shaping device of the present invention, the connecting tip 4 is inserted into the root portion of the hair bundle that is twisted up by a predetermined amount, or the lower hair portion below this, and the separation end portion is inserted. While rotating clockwise, it is screwed in the axial direction front side, and the entire hair shaping device 1 is inserted into the hair. By pushing in the axial direction while rotating the main body, the hair bundle is wound up by a predetermined amount into the winding space formed in the twisted curved surface along the axial direction. Since the separation end part is bent outward and protrudes, it is necessary to prevent the body from recognizing the position of the main body during screwing or to be screwed in the opposite direction, and in line with the intention of the hair to be set. A reliable hair stop can be performed.

  Also, the main body can be screwed from above near the base of the hair bundle with the connecting point facing diagonally downward, and then the hair bundle can be turned up to stop winding up and screwed upward slightly. Thus, the body can be buried from below the hair bundle to stop the hair.

  In addition, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.
