Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a heating hair iron that forms curls and waves in hair.

[Background technology]

In this type of hair iron, if the hair curling rod with a built-in heater is connected and fixed to the grip case in a substantially straight line, the whole iron becomes long and bulky, making it inconvenient to carry or store when traveling.

For this reason, in the past, there are devices that shorten the overall length by allowing the hair wrapping rod to be inserted into the grip case (for example, Japanese Patent Publication No. 53-345, Publication of Utility Model Publication No. 54-8948). In the case of a hair curling rod with a large diameter, the grip part case must be formed thickly, which makes the grip part case difficult to grip during actual use. In addition, the surface temperature of the hair curling rod has reached around 100 to 150 degrees Celsius immediately after use, so if you insert it directly into the grip case, heat will build up inside the grip case and damage the grip case itself. The problem is that it has a negative effect on internal components.

[Purpose of invention]

This invention focuses on such facts, and even if the hair curling rod is hot immediately after use, it will not affect the built-in parts inside the grip case, and the overall length can be increased without making the grip case thick. The first thing is that it can be folded short for easy carrying and storage.
The purpose of If you simply fold the hair rod against the grip case, the hair rod will be exposed, so if you put it in a travel bag, etc., it will receive a strong impact load from another hard object, causing the hair rod to dent and become deformed. Also, there is a risk that the heat of the hair rod immediately after use may cause thermal deformation on other objects, so the second purpose of the present invention is to solve these problems.

[Summary of the idea]

In order to achieve the above object, in the present invention, as shown in the drawings, a hair wrapping rod 2 with a hair presser plate 3 is rotatably connected to the grip case 1, and when in use, the hair wrapping rod 2 is rotatably connected to the grip case 1. The hair wrapping rod 2 is in a position extending in a substantially straight line in front of the case 1,
When not in use, the hair winding rod 2 can be folded together with the hair press plate 3 towards the grip part case 1 side. Then, the protective cover 15 is attached to the grip case 1, and the hair press plate 3 is folded with this protective cover 15.
It is designed to cover the hair curling rod 2. This protective cover 15 serves to make up for the front and rear effective grip length which is insufficient in the grip part case 1, if necessary. Protective cover 1 for grip case 1
As for the specific mounting means 5, it may be a rotating type as shown in FIG. 1, or a sliding type as shown in FIG. 12.

〔Example〕

1 to 7 show a first embodiment of the hair iron according to the present invention, which includes a grip case 1 and a hair curling rod 2 that holds the hair in place to form curls and waves. and a hair press plate 3.

The entire grip case 1 is formed into an elongated cylindrical shape from front to back, and is formed by overlapping left and right split cases 1a and 1b, preferably made of heat-resistant plastic material, and joining them together with screws 4. . A power cord 5 is led out from the rear end of the grip case 1, a lead wire 6 connected to the power cord 5 is passed through the case 1, and a groove 7 is formed on the ventral (lower) side of the case 1. It is formed along the longitudinal direction.

The hair curling rod 2 is made of a metal pipe and has a built-in heater (not shown) connected to the lead wire 6. A rod base 8 made of a heat-resistant material is integrally connected to the base end of the rod 2, and the rod base 8 is fitted between the front ends of the grip case 1 and is rotatable around a shaft 9 surrounding the screw 4. Concatenated. Thus, the hair wrapping rod 2 is in a usage position in which it is substantially in a straight line in front of the grip case 1 (see Fig. 1).
The rod 2 is rotatable around the axis 9 between the folded position (see FIG. 4) in which a part of the outer periphery of the rod 2 fits into the groove 7 on the ventral side of the grip case 1.

A hair press plate 3 is attached to the back side of the hair winding rod 2 in a covering manner along the longitudinal direction of the rod. This hair holding plate 3 is formed in a partially arcuate shape along the upper outer periphery of the circular hair wrapping rod 2, and is integrally provided with an operating plate 10 at its base end. The operation plate 10 is pivotally connected on the rod base 8 with left and right shafts 12 so as to face a spring receiving box 11 integrally formed on the rod base 8. A return spring 13 is interposed between the operation plate 10 and the spring receiving box 11, and the force of the return spring 13 presses the hair press plate 3 so that it is always in close contact with the back surface of the hair winding rod 2. energized. Return spring 1
3, the hair press plate 3 rotates around the shaft 12 and its tip side floats upward away from the hair wrapping rod 2. When the pressing force is released, the hair is returned by the spring 13. The presser plate 3 is brought into close contact with the back surface of the hair wrapping rod 2 in parallel to the original state. In addition,
The spring receiving box 11 is inserted into a recess 14 formed at the upper rear side of the shaft 9 at the front end of the grip case 1 when the hair wrapping rod 2 is in a substantially straight position as shown in FIG. Get into it.

The grip case 1 has a hair press plate 3 on the bottom side of the handle case 1.
A protective cover 15 having a shape and size to cover the hair curling rod 2 when it is folded is also attached.

The protective cover 15 has a groove-shaped cross section, and its rear end is rotatably attached to the rear end of the grip case 1 around a shaft 16 to hold the hair wrapping rod 2 in the folded position. It is possible to switch between a covering position and an open position. The protective cover 15 is provided with heat radiation holes 17 at several locations.
Even when a heated hair curling rod 2 is covered, the heat is quickly dissipated and cooled without being trapped inside.

It also has locking means for holding the protective cover 15 in a closed position covering the hair wrapping rod 2. As the locking means, for example, concave and convex portions 18 and 19 are provided on the protective cover 15 and the grip case 1 so that the protective cover 15 and the grip case 1 can be engaged with and disengaged from each other as the protective cover 15 is rotated to open and close.
Alternatively, it is conceivable to provide a torsion coil spring (not shown) on the shaft 16 and use the spring to always bias the protective cover 15 to close and rotate.

In FIG. 7, the grip case 1 has a locking means for holding the rod 2 in a substantially straight position in use. As the locking means, a lock receiving piece 20 is provided rearwardly protruding from the rear end of the spring receiving box 11 of the rod base 8, and a lock pawl 21 with a knob is provided at the rear of the recess 14 of the grip part case 1 in the front-rear direction. Attaches freely by sliding. The lock pawl 21 is always urged forward by a spring 22 disposed behind it, and its tapered tip 21a protrudes into the recess 14 from a hole 23 on the rear surface of the recess 14 to lock the lock pawl 21. The upper surface side of the receiving piece 20 is held down, and the rod 2 is held in a substantially straight position in use by this holding.

When the lock pawl 21 is slid backward to remove its tapered tip 21a from the lock receiving piece 20, the hair curling rod 2 is moved along with the rod base 8 and the hair presser plate 3 around the shaft 9 by approximately 180 degrees in the direction A in the figure. As shown in FIG. 4, part of the outer periphery of the hair wrapping rod 2 enters into the groove 7 on the ventral side of the grip case 1, and the lower surface of the rod 2 is covered with the hair presser plate 3. A folded state is obtained. After folding this hair curling rod 2, protect cover 1
When the protective cover 15 is rotated forward around the shaft 16 and folded parallel to the ventral side of the grip case 1, the hair wrapping rod 2 is placed in the groove of the protective cover 15 in a covered state.

When the protective cover 15 is rotated from the folded state to the opposite rear and the hair wrapping rod 2 is rotated upward approximately 180 degrees, the spring receiving box 11 of the rod base 8 moves into the recess 14 on the grip case 1. Go inside. At this time, the lock receiving piece 20 at the rear end of the spring receiving box 11 presses into contact with the tapered surface of the tapered tip 21a of the lock pawl 21, and the lock pawl 21 is temporarily retreated against the force of the spring 22. At the same time as the lock pawl 21 overlaps the inner wall surface of the recess 14, the lock pawl 21 slides forward by the force of the spring 22 and engages with the lock receiving piece 20, so that the rod 2 is in a substantially straight position in use. Retained. In this state of use, as shown in Figure 8, the protective cover 1
By making the grip portion 5 project horizontally toward the rear of the grip case 1, the effective grip length can be increased.

[Another example]

The entire details of the embodiments shown in FIGS. 1 to 8 are as described above, but the present invention is not limited thereto. For example, as shown in FIG. 9, the power cord 5 may also be housed in the protective cover 15 together with the hair wrapping rod 2 with the hair press plate 3. In this case, the entire hair holding plate 3 or at least the outer surface thereof is made of a heat-poor conductor made of a heat-resistant plastic material such as phenolic resin, so that even if the hair curling rod 2 is folded immediately after use, the power cord 5 will not be heated. It is desirable to avoid any influence.

Further, as shown in FIGS. 10 and 11, recesses 23 are formed on the back side of the grip case 1 and on the back side of the protective cover 15, respectively, and the recesses 23 are used to form a surface on the outer surfaces of these 1 and 15. The power cord 5 may be wrapped and stored along the rotational direction of the hair wrapping rod 2. In this case, wrapping the power cord 5 around the protective cover 15 can also prevent the protective cover 15 from opening and rotating unexpectedly.
It would be more convenient if the outlet 5a of the power cord 5 could be inserted into the side surface of the grip case 1 and fixed.

Furthermore, as shown in FIG.
On the other hand, the protective cover 15 is attached so that it can be slid forward and backward, and the front slide covers the hair wrapping rod 2 in the folded position, and the rear slide covers the hair wrapping rod 2.
It may be possible to open the .

[Effect of idea]

As explained above, according to this invention, the hair wrapping rod 2 is pivotally connected to the grip part case 1 so that the hair wrapping rod 2 can be folded toward the grip part case 1 side, and the hair presser The plate 3 is attached to the back side of the hair wrapping rod 2 and rotates together with the hair wrapping rod 2. Therefore, you can get a compact folded state and carry it,
Convenient for storage. Grip case 1 This itself is easy to use without making it unnecessarily thick. Since the hair wrapping rod 2 exists outside the grip case 1 in the folded state, the grip case 1 and its built-in parts can be effectively protected from the heat of the hair wrapping rod 2.

Moreover, since the hair wrapping rod 2 with the hair presser plate 3 is covered with the protective cover 15 in the folded state, the hair wrapping rod 2 does not swing sideways or wobble when folded and carried. Even if the hair curling rod 2 is folded while still being hot immediately after use, it will not have a thermal effect on other items in a travel bag or the like. It is also possible to effectively prevent the hair press plate 3 and the hair winding rod 2 from coming into contact with other objects and being deformed.
