Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a hair iron that curls and waves head hair or body hair of pet animals using a heated iron tip.

Improvements in hair irons have focused mainly on changing the cross-sectional shape of the iron tip, and many types have been developed, and even now, products are being commercialized one after another. However, all conventional hair irons have a simple iron structure with a rod with a built-in heater on one side and a glove on the other. It created wavy curls by wrapping the hair around the iron by rotating the entire iron.

The rotating motion of the hair iron to create these waves and curls requires a rotation of around 180 degrees.
Since the rotation range of the human wrist joint is exceeded, the current situation is to rotate the iron by the necessary angle by rotating the wrist to its maximum extent, turning the palm of the hand, assisting with the fingertips, and using it in combination with the arm joint. This movement is very tiring for the worker and involves complicated joint movements, so the hair may not be caught tightly, bent, or bent.
This poses a problem in that it requires a high level of skill and experience since it causes sagging of the hair during wrapping.

The present invention solves these problems and provides an excellent hair iron that allows anyone to curl easily and in a short time without the need for highly skilled hair iron rotation operations such as rotating the wrist joint, turning the palm, or using the fingertips. It is about providing.

The gist of the present invention is to rotatably attach a tip of a hair iron with a rod with a built-in heater and a glove in a normally open state to a hair iron grip, and to operate the iron tip by rotating a rotary operating lever pivotally supported on the hair iron grip. The hair iron is provided with a rotation mechanism for rotating the tip, and is further provided with a finger operation lever mechanism for closing the glove by operating a lever pivotally supported at the tip of the hair iron grip apart from the rotation mechanism.

Embodiments of the present invention will be described below with reference to the drawings. A tubular heater 7 with a heater wire 30 inserted therein is housed inside the rod 1, and the heater wire 30 of the heater is passed through the rod rotating shaft 5 and into the slip rings 31, 3 at the end of the hair iron grip 3.
2 and is connected to the power cord 8 via brushes 33 and 34 that are in contact with the slip ring. Most of the globe 2 has a U-shaped cross section,
The proximal end thereof is pivotally connected to the proximal boss portion 9 of the rod 1, and is held in a normally open state by a spiral 10. A pressure receiving protrusion 1 is provided at the base end of the globe 2.
1 is provided. Further, the boss portion 9 of the rod 1 is provided with a recess 12 into which the tip of the rod rotation shaft 5 is inserted, and the tip of the rod rotation shaft 5 is inserted into the recess.
Moreover, they are connected and fixed by a set screw 13.
The set screw 13 is inserted into the annular groove 3 at the tip of the rod rotating shaft 5.
5 is inserted and connected by crimping. A screw knob 13' is attached to the set screw 13. By loosening the set screw 13, the tip of the rod 1 and the glove 2 can be rotated from the boss 9, and the set screw 13 can be tightened to have an appropriate phase angle with the rod rotation axis 5. Therefore, it can be fixed (see Figures 6a and b).

A flanged sleeve 6 is slidably attached to the outer periphery of the tip of the rod rotating shaft 5.
A hair iron grip part 3 serving as a body is attached to the outer periphery of the hair iron via a bearing 14. The grip of the hair iron has an easy-to-grip shape that fits the palm and fingers and is ergonomically designed for ease of operation.

A lever 4 for releasing the glove 2 is pivotally attached to the tip of the hair iron grip 3 about a pivot point 15, and its free end extends to a sleeve 6, and a roller 16 is attached to the tip of the lever 4, which is attached to the flange of the sleeve 6. Press 17 and insert the sleeve into rod 1.
It can be moved in the distal direction. The lever 4 is normally operated by a spring 10 so that the proximal end of the globe 2 is connected to the flange 1 of the sleeve 6 via the pressure receiving protrusion 11.
Since it is in the state of pressing 7, it is in the state of standing up. Further, a finger hook portion 36 is provided at the tip of the lever 4 to improve the finger hook.

The rotation mechanism A has a rack rod 21 having a rack 20 carved therein pivoted to the free end of a rotary operation lever 19 provided on the outer periphery of the hair iron grip 3, and a protruding portion of the rod rotation shaft 5 from the base end of the hair iron grip 3. A spur gear 22 and a rack 20 are engaged with each other. Moreover, the guide roller 2 is placed on the outside of the rack rod 21.
3 is provided to allow the rack 20 to engage and move forward and backward smoothly. A spring 24 for returning the rotary operation lever 19 is attached. Furthermore, a stopper screw 37 for adjusting the rotation angle of the iron tip is screwed onto the rotary operation lever 19, and by moving the stopper screw forward or backward, the rotation angle of the rotary operation lever 19 can be controlled, thereby adjusting the rotation angle. .

In this embodiment, the glove 2 is opened by the spring 10 unless the tip of the lever 4 is pressed with a finger. When the hair D is caught between the open glove 2 and the rod 1 and the lever 4 is pressed with a finger, the lever rotates clockwise and the roller 16 at the tip of the lever rotates clockwise.
presses the sleeve 6, moves the sleeve toward the distal end of the rod 1, and the flange 17 of the sleeve 6 presses the pressure-receiving protrusion 11 at the proximal end of the globe 2, rotating the globe 2 clockwise against the spring 10. The glove 2 is moved to close the glove 2 and grasp the hair D (see Fig. 7).

Next, when the rotation operating lever 19 is pressed, the rack rod 21 moves downward, the spur gear 22 meshed with the rack 20 rotates, and the rotation of the rod rotating shaft 5 to which the spur gear 22 is attached causes the rack rod 21 to move downward.
The entire tip of the rod 1 and glove 2 connected to the tip also rotates. When the iron tip rotates while holding the hair, the hair wraps around the rod 1, and the entire hair iron is pulled toward the root of the hair by the subtle tension of the hair. If you release the lever 4 after curling your hair for a few seconds in this way, the glove 2 will be released by the spring 10 as described above, and if you pull out the entire hair iron in this state, it will be pulled out from your hair. becomes. Also, depending on the height of your head, the position of your hair, etc., you can choose between rod 1 and glove 2.
If it is better to change the rotation angle of the iron tip, loosen the set screw 13, rotate the iron tip from the recess 12 of the boss 9, set the desired phase, and then tighten the set screw 13 again. This makes it easier to use the hair iron by easily changing the direction of the iron tip. Also, it is easy to replace the iron tip.

As described above, according to the present invention, the iron tip can be freely rotated by the rotation mechanism A, and can be opened and closed by the finger operation lever mechanism, so there is no need for advanced rotation operation or skill of the hair iron. An excellent effect can be obtained in that anyone can perform curling work easily and in a short time.
