Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair iron for use in waving and curling hair.

[0002]

2. Description of the Related Art As is well known, a hair iron is composed of a rod having a built-in heater to enable heating, and a glove for holding hair close to the rod,
The hair is pressed against the peripheral surface of the rod by the gripping operation of the handle, and the hair is curled or curled by the pressing and heating, or the hair with the wave is straightened.

Conventionally, the operation of attaching a wave or a curl or straightening is performed by appropriately selecting an iron having a different cross-sectional shape of a rod, for example, when attaching a wave or a curl. Is done using an iron with a round rod shaped rod with a circular cross section adapted to the desired wave shape and curl shape.

[0004] To explain further, when attaching a wave,
Hair is passed between a round rod-shaped rod and a glove, gripped by a handle grip operation, and forcibly bent by heating while pressing the hair against the peripheral surface of the rod to form a wave.

[0005] In this case, specifically, the portion to which the wave is applied is sandwiched, and after forming one bend, the grip of the handle is loosened to move the hair a little in the length direction, and the hair is gripped again and the hair is rod-shaped. Press and bend against the peripheral surface of
By repeating this, a large number of bends are continuously arranged adjacent to each other, and one wave is formed as a whole by the assembly.

For this reason, when a wave or a curl is conventionally formed on hair, a rod according to its size or shape is selected. On the other hand, in actual work, as described above, the rod and the glove are pinched. The formation of the bent portions and the continuation thereof, and the selection of the continuous range and the selection of the interval between the bent portions, etc., are combined to form waves of various desired forms.

[0007] The formation of curls and waves by this iron eventually starts with the selection of irons with different rods, but more importantly, the movement and bending of the rod as described above when using these irons. The shape and strength are determined by the continuous state of the parts and the adjustment of the spacing between the bent parts, and the grip of the handle, that is, the pressing of the hair against the rod, etc., the shape and strength are determined. It is something that is done by. In other words, a high level of skill is inevitably required here.

[0008]

SUMMARY OF THE INVENTION As described above, the present invention relates to a conventional wave or curl shape,
In addition to preparing multiple special irons with different rod shapes, it was developed with the aim of improving this in view of the fact that anyone who is not experienced in handling irons can freely shape waves and curls It was done.

As described above, for example, when a wave is applied to hair, the hair is conventionally pressed by a glove being pinched on the peripheral surface of a round rod, and the hair is bent along the shape of the curved surface of the rod. However, in order to surely realize the bending, the conventional iron has adapted the pressing surface of the glove to the shape of the peripheral surface of the rod. In other words, when the rod has a circular cross-sectional shape, the pressing surface of the glove is formed into a shape having the same curvature as the curvature of the peripheral surface, and when the hair is pressed, the entire width of the glove is pressed against the peripheral surface of the rod. The hair portion sandwiched between them is designed so that the peripheral surface of the rod is securely pressed against the peripheral surface of the rod to form a bent shape along the peripheral surface of the rod.

Therefore, when the hair is pressed against the peripheral surface of the rod by the glove, the entire surface of the opposing glove uniformly presses against the peripheral surface of the rod, thereby forming a curved shape along the curved surface of the peripheral surface. However, when the squeezing operation is performed at the same time, the rod and the glove come into full contact with each other, making it difficult to adjust the clamping pressure. In other words, if the grip of the handle is strengthened, the contact surface between the rod and the glove will be uniformly tightened over the entire surface, and if it is loosened, the clamping force will be weakened over the entire surface and it will be loose as it is is there.

Therefore, in the case of the conventional iron, it is difficult to adjust the pinching of the hair, that is, the pressing force, so that the handle is squeezed and pressed even when the rod is moved along the hair, and the iron moves when heated. As described above, it was necessary to form the wave as described above while gradually moving it by repeating loosening, pressing, and heating once without loosening the grip without stopping.

The present invention has been developed in view of the difficulty of pinching hair between a rod and a glove in the conventional wave forming with an iron. An object of the present invention is to provide a hair iron capable of forming a wave of an arbitrary shape by allowing the rod to slide in the length direction of the hair while maintaining a heated state by pressing.

The formation of waves and curls can not only be formed by pressing hair on a rod,
It is well known that a wave or a curl can be applied by sliding and moving the rod in the length direction of the hair while maintaining the pressed state. The present invention has been made in view of this point, and it is an object of the present invention to provide a hair iron that can be heated while keeping the hair pressed against a rod, and can be slid and moved in the length direction of the hair in that state. .

Further, the present invention is also directed to a hair in which a wave or a curl having a different strength can be arbitrarily shaped by moving the hair while pressing the rod against the rod and moving the hair while maintaining the heated state. It is intended to provide an iron for use.

Another object of the present invention is to provide a hair iron in which the bending strength of a wave or a curl can be arbitrarily selected by changing the direction in which the hair is wound around the rod.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION

1 is a perspective view of a hair iron according to the present invention, FIG. 2 is an enlarged sectional view of a rod and a glove taken along a line AA in FIG. 1, and FIG. 3 is hair of the present invention. It is explanatory drawing explaining the wave forming operation | work by the iron for use. Reference numeral 1 in the drawing denotes a rod, 2 denotes a glove, and 1a, 2a
Is a handle for operating the rod and glove, 3 is a temperature adjustment unit for adjusting the temperature of a heater (not shown) built in the rod 1, and 4 is a power cord of the heater.

As shown in FIG. 1, this hair iron is formed into scissors in appearance which is not different from a conventional iron. The rod 1 and the glove 2 are opened and closed with the hinge portion 5 as a fulcrum by the gripping operation of the handles 1a and 2a, the hair H passing between the two is clamped, and the hair H is pressed against the surface of the rod by the glove 2. is there. The rod 1 is given a temperature (in this case, it can be set in the range of 120 ° C. to 220 ° C.) set by operating the knob 6 of the temperature control unit 3, and the hair 1 is pressed against the hair H to be pressed. It can be heated at a desired temperature.

FIG. 2 is an enlarged sectional view of the rod 1 and the glove 2 of the hair iron according to the present invention. As shown here, the rod 1 is formed to have a substantially elliptical cross-sectional shape, and in the drawing, two gentle convex arc portions 7 and 8 are vertically arranged.
Is formed in an elliptical cross-sectional shape having two sharply convex arc surface portions 9 and 10 on the left and right.

More specifically, in this embodiment, one of the left and right suddenly convex arcuate surfaces 9 and 10 sandwiching the upper and lower gentle convexly arcuate surfaces 7 and 8 is replaced by the other. It is formed so as to form a convex arc surface with a curvature larger than 10, and to make a difference between the two, so as to form an egg-shaped oval cross section as a whole.

The glove 2 is provided on the rod 1 so as to face one of the gentle convex arc surfaces 7.
The squeezing surface 11 is pressed against the gentle convex arc surface portion 7 by the gripping operations of a and 2a.

The globe 2 is formed in a slightly concave arc surface shape having a gentle arc surface corresponding to the gentle convex arc surface portion 7, and here, it is possible to cover almost the entire surface of the gentle convex arc surface portion 7. The rod 1 is formed so as to have a width that exceeds a possible size, that is, the length of the major axis (the direction of the line a) of the rod 1 as shown in the figure.

In the globe 2 shown here, the curvature of the gentle concave arc surface forming the narrow pressure surface 11 is formed slightly larger than the curvature of the gentle convex arc surface portion 7 of the rod, and the two surfaces 7, 11 are brought into contact with each other. When the rod 1 and the glove 2 are closed by the gripping operation of the handles 1a and 2a, the two surfaces are in line contact along the length direction.

The solid line in FIG. 2 shows a state where the glove 2 is separated from the rod 1, and the two-dot chain line shows a state immediately before the glove 2 comes into contact with the gentle convex arc surface portion 7 by the grip of the handle. When the glove 2 is tightened in this state, the glove 2 abuts on the rod at a point P shifted slightly to the left from the center position of the narrow pressure surface 11, and both lines come into line contact at the position of the point P. Then, at the time of contact between the two surfaces, two substantially V-shaped gaps 12 and 13 are formed between the rod and the globe and gradually open outward to the left and right with the contact point of point P therebetween.

The line contact portion between the rod 1 and the globe 2 at this point P is an area where the strongest pressing force can be applied to the hair H when the handles 1a and 2a are gripped and clamped. The two V-shaped cavities 12, 13 which gradually open toward the end are auxiliary pressing force action areas for decreasing the pressing force as the distance from the point P is increased. Form a narrow pressure area for the hair H.

In this embodiment, the line contact point P between the rod 1 and the globe 2 is set at the center line b along the minor axis direction of the rod 1.
The deviation to the left is due to the fact that the rod 1 has an elliptical cross-section deformed into a chicken egg shape. In the case of a simple elliptical cross-section, the line contact point P is located on the center line b. Will be located. In addition, the left and right gaps 1
2, 13 will be symmetrical.

Of course, the movement of the position of the contact point P is automatically caused by the change of the elliptical cross-sectional shape of the rod 1, but the present invention includes all the changes of the shape. Does not prevent effective implementation. In other words, what is important between the rod 1 and the globe 2 is that both the convex arc surface portion 7 and the concave arc pressing surface 11 come into contact with each other along the length direction in a line contact state. Void portions 12 and 13 having a substantially V shape are formed on the sides of the contact point to form a narrow pressure area, and the shape of both rods, that is, the shape of the rod and the glove is changed as long as this condition is satisfied. Will be allowed.

Also, the rod 1 and the globe 2 have been described with a cross section taken along the line AA in FIG. 1. Here, the elliptical cross section of the rod 1 and the concave arcuate cross section of the globe 2 are described. Are formed to have the same cross-sectional shape over the entire length of the effective operation range, that is, the entire length from the base end portion adjacent to the hinge portion 5 to each of the distal end portions.

The hair iron of the present invention is constructed as described above. Next, its use will be described and its features will be described in detail. FIG. 3 shows a case where the hair H is waved using the iron of the present invention. In each of the drawings (A), (B), (C), and (D), the rod 1 and the globe 2 are cut in the middle of the length in the same manner as in FIG. Is what I saw.

FIG. 3A shows a hair H that grows from the head 14 (here, it is represented by a single hair for convenience of explanation.
In the actual work, a plurality of hairs are put together. ) Is sandwiched between the rod 1 and the glove 2. The hair H is pressed by the strongest pressing force at the point P where the hair H comes into line contact with the pinch, and the pressing force becomes smaller as the hair H moves away from the point P toward the both side edges of the glove 2. Open to the public.

That is, the hair H is applied to the gentle convex arc surface 7 of the rod 1.
And the entire pressure is sandwiched between the narrow pressure surface 11 having a concave arc shape of the globe 2, and is substantially compressed at the position of the point P that substantially makes line contact. In this case, the pressure is reduced because the pressure is weakened.

The compression of the hair H is performed as a whole in the arc-shaped space formed on the gentle convex arc surface 7 on the peripheral surface of the rod 1, that is, in the narrow pressure area including the gaps 12 and 13. When the hair H is pinched, the hair H is automatically forcibly shaped into a shape along the arc surface.

In the state shown in FIG. 3A, when the handles 1a, 2a are squeezed and the pressing force of the glove 2 is increased, the hair is heated by the rod, and the hair H exhibits a bend along the gentle convex arc surface of the rod. If you then loosen the grip, only the bending of this part will remain on the hair.

Next, when the hair is pressed by the grip of the handle and the iron is moved in the direction of the hair tip (upward in the drawing), the narrow pressure area formed by the rod and the glove with this movement. Will appear on the hair passing through the arc along the arc surface of the pinching area.

During the movement of the iron, in the iron of the present invention, the pressing force and heat necessary for forming a wave are applied to the hair at the point P as described above, and at the same time, the point P, that is, the portion in line contact The whole of the narrow pressure area, including, is easy to slip because it corresponds to the gentle curved surface of the peripheral surface of the rod, so that the hair that has been pinched can be slid, and the rod 1 and the glove 2 can be easily applied to the hair. It can be moved along.

Moving the iron while holding the hair is to form a wave, but by further changing the grip of the handle, the degree of the wave can be changed. Of course, it is needless to say that the wave can be reliably formed and the shape can be stabilized by repeatedly applying the same portion to the hair.

In FIG. 2B, the wrist is further turned back from the state shown in FIG. 2A and the rod 1 is slightly rotated about the rod 1 so that the hair H is wrapped around a part of the steeply arcuate surface 9 of the rod. FIG. The winding of the hair by the rotation of the rod 1 strengthens the wave formation on the hair, and the hair is angled by shifting the contact point from the gentle convex arc surface portion 7 to the sharp convex arc surface portion 9. Accordingly, a somewhat strong wave can be formed.

According to the ratio of the sharply convex arc surface portion 9,
That is, when the rod is further rotated and the portion of the hair covering the sharply convex arc surface portion 9 becomes longer, the wave becomes stronger and more reliable. In this case, when the pressing force by the glove 2 is increased, the pressing force against the sharply convex arc surface portion is increased, so that a stronger wave is applied. On the contrary, when the pressing force is reduced, the pressure is released from the pressure contact with the rod, so that the slip is smooth. , And at the same time, a gentle wave is given by the curved surface of the steeply convex arc surface portion 9 acting.
Of course, also in this case, the wave can be strengthened or enlarged by repeating the number of times.

FIG. (C) shows that the rod 1 is rotated by 180 °,
In this case, the hair H is brought into contact with the entire surface of the steeply convex arc surface portion 9 of the rod 1 and further with the other gentle convex arc surface portion 8. The rotation of the rod 1 is an operation for forming a strong wave, and at the same time, the adjustment of the pressing force by the globe 2 and the movement of the rod, that is, the movement of the rod, that is, the formation of a wave of a different shape by sliding along the hair. Then, it will be arbitrarily selected according to the desired hair style.

FIG. 4D shows a case where the hair is wound once around the rod by rotating the rod 1 once. Although the winding of the hair around the rod affects the strength of the wave, the curl can be changed from the wave state to the curl by further winding the hair once. This change is also made by the pressing force of the glove and the contact time with the rod, that is, the heating time.

In the above description, the hair is wound around the steeply convex arc surface portion 9 when the hair is wound by the rotation of the rod 1.
When the rod is rotated so as to be wound around the sharply convex arcuate surface portion 10 having a smaller circular arc than the sharply convex arcuate surface portion 9, it is possible to easily form a strong wave. Become.

That is, in the present embodiment, the shape of the wave or curl is changed by the winding of the hair on the rod, the pressing force, the heating time, the number of repetitions, etc., while the winding direction on the rod 1 is changed. Changes can be made by this.

Although the present invention has been described with reference to the illustrated embodiment, it is assumed that the cross-sectional shape of the rod 1 is made elliptical and the glove 2 is opposed to one of the slightly convex arc-shaped surface portions 7 so that the hair is pinched. In doing so, the two are brought into line contact along the longitudinal direction so that a sufficient pressing force can be applied partially, and on the gentle convex arc surface portion 7 of the rod, the side of the rod centered on the line contact portion V-shaped voids 12 and 13 that gradually open outward toward the outside are formed, so that the pressing force at the time of pinching is gradually weakened from the center position to the side, thereby allowing the hair to pass through. Resistance can be reduced, so that a sufficient pressing force can be applied to the hair during the pinching operation, and at the same time, the hair can be heated by a heater, and the hair can be set in a gentle curved space. Press It has become one that can pass slid while heating the hair without being subjected to extreme resistance from Rukoto.

The fact that the rod is slid on the rod while being heated to a required temperature by applying the pressing force is effective in forming a continuous and smooth wave.
Further, in the present invention, it is possible to incorporate an operation of changing the pressing force in addition to the sliding operation and further adjusting the winding of the hair around the rod to wind the hair around the sharply convex arc surface portion 9 or 10 of the rod. As a result, it is possible to easily form a wave or a curl with a change.

In the description of the above embodiment, it has been described that the abutment of the narrow pressure surface 11 of the globe 2 with the gentle convex arc surface portion 7 of the rod is a line contact at the point P. It does not specify the contact state, but allows a certain width along the line, and in effect, the part where the pressing force acts strongly along the line when the rod and the glove abut by pinching However, it is only necessary that the part that acts weaker as the distance from this part is continued next to each other.

Further, in the embodiment, the globe 2 has been described in the case where the narrow pressure surface has a gentle concave arc shape, but may be flat. What is required here is a linear contact with the surface of the rod 1 (slowly convex arc surface portion 7), and the gap portions 12 and 13 which form a substantially V-shape from the contact portion to the side are formed. Therefore, a space that gradually expands outwardly at the time of abutment between the rod and the glove is formed as a whole, and it is satisfied that the pinching area is provided.

In addition to this, it is desirable that the width of the globe 2 is preferably equal to or larger than the width of the long diameter side of the rod 1. As a result, the hair to be narrowed is more effectively in contact with the surface of the rod, and the hair can be widely heated from a strong heating area to a weak heating area, so that the heating can be easily adjusted in accordance with the grip adjustment of the handle.

[0052]

As is clear from the above description, the hair iron according to the present invention has a line contact portion centered on the point P when the glove is pressed against the rod by the gripping operation of the handle to pinch the hair. While strong pressure can be applied, the V-shaped voids formed on both sides have an area where the pressing force is gradually reduced outward, so that pinching on the hair does not become extreme, and a simple grip is achieved. Since the pressing force against the hair can be adjusted gradually by strengthening or loosening the operation, it is easy to adjust the pressure and there is an advantage that it can be handled without requiring skill.

Further, as described above, it is easy to attach the wave to the hair, the strength can be easily adjusted, and at the same time, the wave can be slid in the sandwiched state, so that a smooth wave can be formed. In the conventional repetition of pinching and loosening operations, a wave is formed by increasing or decreasing the tightening force, but the operation is much easier, and a natural wave and curl can be easily formed. This is extremely advantageous because it can be performed.
