Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to an electric pine hair curler for curling pine hair.

[Conventional technology]

A conventional pine hair curler, as shown in FIGS. It consists of a movable clamping part 4, operating rods 5, 6, and an operating pin 7 for sliding on the movable clamping part 4, and by inserting fingers into the operating pins 3 and 7 and bringing them close together, the fixed clamping part 2 and The movable clamping part 4 closes to clamp the pine hair.

To curl the pine hair with this pine hair curler, as shown in FIG. Squeeze in a circular motion to mechanically create a curl.

Note that the opposing surfaces of the fixed clamping part 2 and the movable clamping part 4 are as follows:
As shown in FIG. 13A, one side is formed as a convex surface 2a and the other as a concave surface 4a, and as shown in FIG. Pinches the pine hair as shown in Figure 14 A or B.

[Problem that the invention seeks to solve]

However, with such a conventional pine hair curler, as shown in Fig. 14 A or B, the pine hair is hardly curled just by holding it, so as shown in Fig. 12 A to D. Since the pine hair is mechanically curled by pinching and squeezing the pine hair, there have been problems such as stress on the hair roots, causing pain and causing the hair to fall out.

Furthermore, the curls formed in this way return to straightness within a short period of time, which is very inconvenient.

On the other hand, there has been a hair iron 11 for curling hair as shown in FIGS. 15 and 16, which has a rod-shaped high temperature part (130
℃) 12 and the presser plate 13 to sandwich the hair 14,
It curls the hair by applying heat at the same time, and since it does not apply excessive force to the hair roots and heat is applied, the curls last longer.

Therefore, if you use a thin curling iron, you can curl the pine hair, but as shown in FIG. Since the distance S from the eyelids 15 to the eyelids 15 becomes very small, there is a problem that the eyelids 15 may be burned unless advanced techniques are used. It is especially difficult to curl your hair by yourself.

Therefore, for example, a battery-operated hot eyelash curler exclusively used for curling pine hair has been proposed, as seen in Japanese Utility Model Application Publication No. 47-21880.

However, this is because the main case, which is held by hand, and the frame part, which holds the pine hair, extend on the same straight line, so the main case interferes with the face, making it difficult to grasp, and when curling the pine hair on the left side. The device had to be held with the left hand, and the switch's ON/OFF and frame opening/closing pushbuttons had to be operated separately, which caused problems in operability.

In addition, each frame that holds the pine hair is not shaped to fit the curved surface of the eyelid, and it is rotatable like scissors, so you can evenly pinch all the pine hair on one eyelid at once. It was difficult to curl it.

Furthermore, the pine hair is held between a frame with low-current nichrome wire reinforced with metal and wrapped in ultra-thin insulation, and a receiving frame integrated with the main body case, and curled by heating the frame with the nichrome wire. Therefore, since the entire frame with the nichrome wire is heated, there are various problems such as the risk of getting burned if the frame touches the eyelids, so it is hardly used at present.

This invention was made to solve these problems, and even ordinary people without advanced skills can use it without suffering burns or painful hair loss. To provide an electric pine hair curler that can safely and easily give long-lasting curls to pine hair.

[Means for solving problems]

In order to achieve the above object, the present invention provides an electric eyelash curler configured as follows.

The upper clamping piece and the lower clamping piece are made of a heat-resistant material with low thermal conductivity and are curved in the longitudinal direction to fit the curved surface of the eyelid. Each tip is integrally fixed with a concave curved surface facing outward, and the lower edge of the upper clamping piece is a convex clamping part that is convex in the thickness direction, and the upper edge of the lower clamping piece is shaped as a convex clamping part that is convex in the thickness direction. As a concave clamping part having a concave surface, the convex clamping part and the concave clamping part are opposed in a substantially parallel state, and the convex clamping part and the concave clamping part are arranged along the longitudinal direction at the central part in the thickness direction of at least one of the convex clamping part and the concave clamping part. Attach the heating element in an exposed or nearly exposed state.

Furthermore, the first support piece and the second support piece are connected at their respective rear ends or are integrally formed into a U-shape, and are mutually connected to each other by the biasing force of the elastic member or their own elastic force. A battery chamber is provided between the first support piece and the second support piece, and the battery chamber is stored in the inner surface of either the first support piece or the second support piece. A switch for opening and closing the current supply circuit from the battery to the heating element is attached, and the operating piece of the switch is formed in a cantilever shape on the other side.

When one of the first support piece and the second support piece and the other operation piece are held and pressed against the urging force, the convex holding part of the upper holding piece and the concave holding part of the lower holding piece When the operating piece is pressed, the switch is turned on and the switch is turned on, removing the battery from the battery. Electricity is applied to the heating element, and the heat generated by the heating element curls the pine hair.

[Embodiments] Examples of the present invention will be described below with reference to FIGS. 1 to 9.

1 to 4 are a perspective view, a side view, a bottom view, and a vertical sectional view taken along the line B-B in FIG. The upper clamping piece 20 is curved in the longitudinal direction so as to match the curved surface of the eyelid, and the lower clamping piece 21 is curved in the same way in the opposite direction.
2 and the second support piece 23 are integrally formed with concave curved surfaces facing outward at their tips, and the first support piece 22 and the second support piece 23 have disc-shaped fitting parts formed on both sides of the base, respectively. 22a and 23a (FIG. 3), they are connected to each other so that they can rotate relative to each other by a predetermined angle. A cylindrical battery chamber for housing the battery 24 is formed within this base.

As clearly shown in FIG. 3, the second support piece 23 has a cantilevered operation piece 25 cut and raised outwardly at the center in the width direction, and a pair of cantilevered plates on both sides. The spring pieces 26, 26 are cut and raised inwardly, and the tips of the leaf spring pieces 26, 26 are in contact with the inner surface of the first support piece 21, so that the upper holding piece 21 and the lower holding piece 22 are normally held together. As shown in FIGS. 1 and 2, they are arranged to face each other in a substantially parallel state with a predetermined distance d between them.

Further, a switch 27 is attached to the center of the inner surface of the first support piece 22, and the push pin 27
A protrusion 25a is fixedly provided on the operation piece 25 in correspondence with a.

The lower edge of the upper clamping piece 20 is a convex clamping part 20a, and the upper edge of the lower clamping piece 21 opposite thereto is a concave clamping part 21a. As shown in FIG. 5, the convex holding portion 20a is provided with a planar heating element 28 that is slightly retracted from the concave curved surface 20b facing at least the eyelid, and is located near the center in the thickness direction.
is worn in an exposed or nearly exposed condition.

When the heating element 28 is mounted exposed, it is preferable to use a material that is particularly resistant to rust, such as a nichrome strip (a flattened nichrome wire). Since it is exposed to quickly conduct heat to the pine hair, if it rusts, the thermal conductivity will deteriorate and the electrical resistance will change, which is inconvenient.

Among these parts, at least the upper clamping piece 20
The lower clamping piece 21 is made of a resin material that is heat resistant and has low thermal conductivity (high heat insulation properties). In this embodiment, the first and second support pieces 22, 2
3, the operating piece 25, and the leaf spring pieces 26, 26 are also integrally formed of the same material.

The battery 24, switch 27 and heating element 28 are connected in series as shown in FIG.

Next, the operation of this electric lash curler will be explained.

Hold the first and second support pieces 22 and 23 between the fingers of your hands from above and below, bring the upper holding piece 20 close to your eyelids (you may also apply it to your eyelids), and place the convex holding part 20a on the pine of the upper eyelid 15. When the first and second support pieces 22 and 23 are rotated in the closing direction against the biasing force of the leaf spring piece 26 by pressing the operating piece 25 with, for example, a thumb, the upper clamping piece 20
The convex clamping part 20a of the lower clamping piece 21 and the concave clamping part 21a of the lower clamping piece 21 move toward each other while maintaining a substantially parallel state to bend and clamp the pine hair 8.

In this state, when the operating piece 25 is pushed further, the first and second support pieces 22 and 23 do not rotate any further, but the operating piece 25 bends inward, and the protrusion 25a pushes the push pin 27a, turning the switch 27 on. Then, electricity is supplied from the battery 24 to the heating element (heater) 28 to generate heat.

Since the heating element 28 is attached to the convex holding part 20a in an exposed or nearly exposed state, the heat is immediately transmitted to the pine hair, and curling is achieved in a short time when electricity is applied.

After that, when the force pushing the operation piece 25 is relaxed, the switch 27 turns off and the electricity to the heating element 28 is stopped. When the force pushing the operation piece 25 is further relaxed, the force of the leaf spring piece 22 causes the first second support piece 22,
23 is rotated in the opening direction, and the upper clamping piece 20 and the lower clamping piece 21 are opened to release the pine hair 8.

At this time, almost the entire pine hair is curled. Moreover, the clamping pieces 20 and 21 shown in FIG.
By shortening the width l, it is possible to perform partial curling by that width.

The upper clamping piece 20 and the lower clamping piece 21 are made of a material with low thermal conductivity.
Since the heating element 28 is attached to the convex holding part 20a so as to be retracted toward the center in the thickness direction, the heating element 28 does not directly touch the eyelids, and the upper holding piece 20 and the lower holding piece 21 do not become hot. There is no risk of burning your eyelids.

Note that when replacing the battery 24, the first and second
When the support pieces 22 and 23 are strongly opened against each other's frictional engagement force, the battery chamber is opened and the battery 24 can be taken out and inserted.

FIG. 6 is an enlarged sectional view showing the heating element attachment part of the upper clamping piece 20 of another embodiment, in which the upper clamping piece 20 is made of ceramic, and the heating element 28 is attached to the convex clamping part 20a. Furthermore, this heating element 28 is covered with a very thin ceramic coating 29 to provide electrical insulation and to prevent it from rusting. As the heating element 28, it is also possible to use a resistor exhibiting positive characteristics (PTC).

The other configurations are the same as those of the previous embodiment, so the explanation will be omitted.

Ceramic coating 29 is very thin,
It may be about several μm. Therefore, the coating hardly impairs the heat conduction to the pine hair, and the pine hair can be easily curled in a short time as in the above embodiment.

Furthermore, if the pine hair holding part is coated with fluororesin, cosmetics (cream, mascara, etc.) will not stick to it. Also, if you apply thermo paint, etc., you will be able to see changes in temperature, and it will give you a warning when it gets particularly hot.

In these embodiments, the heating element 28 is attached to the upper clamping piece 2.
Although it is attached to the convex holding part 20a of the lower holding piece 21, it may be attached to the concave holding part 21a of the lower holding piece 21, or to both of the holding parts.

Further, the shape of the holding portion may be any shape such as one using an elastic member as shown in FIG. 13B, V-shape, W-shape, etc. In short, any shape is sufficient as long as the pine hair can be bent into any shape and held, and heat can be quickly transmitted thereto.

FIG. 8 is a circuit diagram showing an example of an electric circuit different from that in FIG.
It is a timer that turns off the power to the
Once turned off, a circuit is built in that prevents the power from being turned on again until a certain period of time has elapsed.

In this circuit, when the switch 27 is turned on, the heating element 28 and the buzzer 30 operate. After that, when the set time has elapsed, even if the switch 27 is in the on state, the heating element 28 is activated by the operation of the timer 31.
And the power supply to the buzzer 30 is stopped.

At this time, even if the switch 27 is once turned off and then turned on again, it will not become energized due to the off-state holding circuit (a very common circuit) built into the timer.

When the switch 27 is turned on after a certain period of time has elapsed, the power is turned on again and the buzzer 30 and heating element 28 operate. In other words, by providing a certain cooling time for the heat generated by energization for a certain period of time, the holding portion is prevented from becoming high temperature.

In this way, by making the heating time of the heating element 28 constant or by providing the adjustable timer 31, the heating time of the right and left pine hairs is different, resulting in unbalanced left and right curls, or curls that are longer than necessary. It can prevent the pine hair from burning and the gripping part becoming hot due to heating.

In addition, by adjusting the heat generation time, you can select strong curls, weak curls, etc., so you can enjoy unique curls.

FIG. 9 is a perspective view of still another embodiment of the invention.

In this embodiment, the upper clamping piece 20 and the lower clamping piece 21 are made of a slightly elastic resin material or the like.
integrally formed at both free ends of the first support piece 22' and the second support piece 23', which are integrally molded into a letter shape,
A battery chamber for housing the battery 24 is provided in the U-shaped bent portion.

Embodiment 1 shown in FIGS. 1 to 4
The pair of leaf spring pieces 26 and 26 are omitted, and the first support piece 2
2' and the second support piece 23' have a biasing force in the direction of opening the tip (free end) side only by their own elastic force.

The other configurations are the same as those of the previous embodiment, so the explanation will be omitted.

In this way, the structure becomes simpler than the above-mentioned embodiment, and it is easy to manufacture and can be provided at low cost.

In this way, the structure of the above-mentioned embodiment is simplified, and it can be easily manufactured and provided at low cost.

Furthermore, FIG. 10 is a diagram showing different examples of mounting the heating element, and in both A and B, an elastic member 35 made of heat-resistant synthetic rubber or the like is fitted into the clamping part of the lower clamping piece 21; In case 2, a plate-shaped heating element 28' is vertically projected and fitted into the central part of the clamping part of the upper clamping piece 20 in the thickness direction. It is exposed and buried.

In these examples, the pine hair is bent and held by pressing with the heating element 28' or 28'' so as to push the pine hair slightly into the elastic member 35,
In this state, by energizing the heating element 28' or 28'' to generate heat, it is possible to easily form a habit.

〔Effect of the invention〕

As explained above, when the electric lash curler according to the present invention is used, the first and second support pieces, which are the gripping operation parts, are located behind the upper and lower gripping pieces, so that they interfere with the face. Without a doubt,
Both can be operated with the right hand when curling the pine hair on the left and right eyelids.

Since the upper and lower clamping pieces are curved to fit the curved surface of the eyelid, all the pine hair can be clamped at once when brought close to the eyelid. Since the concave clamping portion of the lower clamping piece moves toward each other while maintaining a substantially parallel state, all the pine hairs can be bent and clamped almost simultaneously and uniformly.

Also, when one of the first and second support pieces and the other operation piece are held and pressed between fingers, both support pieces are first bent in the direction of closing their tips, and the upper and lower holding pieces are used to hold the pine hair. By bending and holding the pine, and then further pressing the operating piece, the switch is turned on and the heating element is energized to curl the pine hair, and then when the pressing force is released, the switch is turned on. First, the switch is turned off, and then the upper and lower grips open to release the pine hair.

Therefore, all operations are performed using the fingers of the hand.
This can be done by simply changing the pressing force while the second support pieces are held in the same state, and is extremely easy to operate.

Moreover, the upper and lower holding pieces are made of a material that is heat resistant and has low thermal conductivity.
Since the heating element is attached to at least one of the convex holding part and the concave holding part along the longitudinal direction at the center in the thickness direction, the surfaces of the upper and lower holding pieces that face or contact the eyelids become highly heated. There is no risk of burning the eyelids due to heating or direct contact with the eyelids, ensuring a high degree of safety.

Moreover, since the heating element is attached in an exposed or nearly exposed state, the heat is quickly transmitted to the pine hair being held, and curling can be achieved in an extremely short time.

Therefore, anyone can easily curl the pine hair by themselves, and depending on the shape of the clamping part, it is also possible to create wavy, V-shaped, W-shaped, etc., so you can create a unique pine hair. You can enjoy it.
