Description

[Detailed description of the invention] This invention relates to a hair iron used to form curls and waves in the hair, and when not in use, the rod with a built-in heater can be folded compactly against the grip case. ,
This makes storage convenient and also protects the spring incorporated to press and bias the hair presser plate against the rod.

Hereinafter, embodiments of this invention will be described based on the drawings.

The drawing illustrates a hair iron according to this invention, which includes a grip case 1, a rod 2 that holds hair to form curls and waves, a hair press plate 3, and a grip part that connects the rod 2 to the hair holding plate 3. It consists of a rod base 4 connected to a case 1.

The entire grip case 1 is formed into an elongated cylindrical shape, and the left and right divided case 1 is made of plastic.
It is formed by overlapping parts a and 1b and integrally connecting them with screws 5. Joints 6, 6 are integrally formed on the front end sides of the left and right split cases 1a, 1b, respectively, and screw bosses 7, 7 into which the screws 5 are screwed are protruded from the inner surface of each joint 6 in an opposing manner. , an annular shaft 8 is provided protruding from the outer periphery of each screw boss 7. A connector (not shown) for connecting to a power cord 9 is built inside the grip case 1.

The rod 2 is made of a metal pipe and has a built-in heater (not shown) connected to the coupler via a lead wire. A rod base 4 is integrally connected to the base end of the rod 2, and the rod base 4 is made of heat-resistant plastic with a left-right split case 4.
The left and right divided cases 4a and 4b each include an annular boss portion 11 having a rotation shaft hole 10 and a rod having a semicircular cross section that protrudes forward from a part of the outer periphery of this boss portion 11. Conjugation cylinder part 1
2. The left and right rod conjugation cylinder parts 12,
The base end of the rod 2 is held between the screws 13 and 12.
are integrally combined. And boss parts 11, 11
are overlapped between the joints 6, 6 of the grip part case 1, and the shafts 8, 8 are rotatably fitted into the rotation shaft holes 10, 10, and the joints 6, 6 are tightened with the screw 5. Thus, the rod 2 can be used in a position in which it is in a substantially straight line in front of the grip case 1 (see Figure 1), and in a position in which it is folded parallel to the lower surface of the grip case 1 (see Figure 6). It is made possible to rotate around the shaft 8 across the body.

At the rear upper part of the front end side of the grip case 1 from the shaft 8, there are rising left and right walls 14 that are inclined upwardly at the rear.
14 and a rising rear wall 15 form an upwardly open recess 17 surrounded on three sides. This recess 1
A spring holding plate 18 is mounted inside the spring holding plate 7 so as to be rotatable around a shaft 19 that pivotally supports the front end of the spring holding plate 18.
A spring 20 is interposed between the spring holding plate 18 and the inner bottom surface of the recess 17. The spring holding plate 18 is constantly urged upward by the spring 20, and the spring holding plate 18 in this biased state is positioned so as to be substantially flush with the upper surface of the opening of the recess 17.

A hair press plate 3 is attached to the upper surface of the rod 2 along the longitudinal direction of the rod.
is formed to have an arcuate cross-section, and is integrally provided with an operation plate 21 at its base end. The operation plate 21 is formed in the shape of a downwardly open box and has an upper wall 22, left and right walls 23, 23, and a rear wall 24.
5 and 25, which are rotatably pivotally connected. As shown in FIGS. 2 to 4, the operation plate 21 is positioned above the recess 17 of the grip case 1 when the rod 2 is in a substantially straight position of use. There is. Therefore, when the operating plate 21 is pushed down while the rod 2 is in a substantially straight position, the operating plate 21 moves into the recess 1.
While pushing down the spring presser plate 18 in 7, it rotates around the shaft 25, and this rotation causes the hair presser plate 3 to move around the shaft 2.
5, and its tip side is separated upward from the rod 2 (see the virtual line state in FIG. 1).

In FIGS. 3 and 6, the grip case 1
Locking means are provided on the lateral sides of the rod 2 to hold the rod 2 in a substantially straight position in use and in a folded position. The locking means is Rod Base 4.
Recesses 26 and 27 are provided at two positions on the outer periphery of the boss portion 11, and a knob 2 is provided at the front inside of the grip case 1a.
A lock pawl 29 with an 8 is attached so as to be slidable in the front and rear directions. The lock pawl 29 is always urged forward by the force of a spring 30 disposed at the rear, and its tip 29a selectively engages the recesses 26 and 27, thereby allowing the rod 2 to be used in a substantially straight line. It can be freely switched between the posture and the folded posture.

Now, when the rod 2 is in a substantially straight position as shown in FIG.
When removed, the rod 2 can be rotated approximately 180 degrees in the direction A in the figure around the shaft 8 together with the rod base 4 and the hair press plate 3, leaving the spring press plate 18 and the spring 20 in the recess 17. As shown in FIG. 6, a folded state is obtained in which the rods 2 are folded parallel to each other on the lower surface side of the grip case 1. This folded state is maintained by the lock pawl 29 engaging with the recess 26.

In this folded state, the operation plate 21 of the hair presser plate 3 tends to protrude downward, so it may be pushed by contact with other objects when carrying or storing it. Since the spring 20 is not pressed, the spring 20 may be deformed by receiving such an unexpected push or being released from the push.
You will no longer experience fatigue. Further, since the spring 20 remaining on the grip case 1 is housed in the recess 17, it is possible to avoid receiving loads from other objects at this location as much as possible.

When the rod 2 is rotated approximately 180 degrees around the shaft 8 in the opposite direction from this folded state, the operating plate 21 is moved into the recess 1 at the same time that the rod 2 is in the usage position.
Located above 7. This usage position is for locking claw 2.
9 is held by engaging with the recess 27.
Therefore, at this time, as mentioned above, the operation panel 2
1 against the spring 20, the hair press plate 3
can be separated upward from the rods 2, and the hair can be sandwiched between the rods 2 and the hair holding plate 3. After this, when the pressure applied to the operation plate 21 is released, the hair press plate 3 receives the force of the spring 20 and maintains the hair sandwiched state.

Note that the spring receiving plate 18 is not necessarily required and can be omitted.

As explained above, according to this invention, the rod 2 is pivotally connected to the grip case 1 so that the rod 2 can be folded compactly with respect to the grip case 1. Extremely convenient for storage. Also, the rod 2, hair press plate 3 and operation plate 21 are placed on the rod base 4 in this way.
According to this structure, when assembling these, if the rod 2, hair press plate 3, and operation plate 21 are assembled on the rod base 4 in advance,
It is sufficient to pivotally support only the rod base 4 for the grip case 1, and the assembly work can be streamlined.

Particularly, in this invention, a recess 17 is formed in the rear upper part of the grip case 1 from the shaft 8, into which the rod 2 enters when the operation plate 21 receives downward pressure in a substantially straight position of use. Since the spring 20 that pushes back the operation plate 21 upward is built into the spring 17, the spring 20 is
This has the advantage that the spring 20 can be prevented from being deformed or fatigued due to loads from other objects, thereby extending the life of the spring 20.
