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 not only makes storage convenient, but also effectively prevents the rod from wobbling or rattling during use.

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.
a and 1b are superimposed and integrally connected by front and rear screws 5, 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. The lower surface of the grip case 1 has left and right ribs 9,
9 are formed parallel to the longitudinal direction of the ribs 9,
A concave groove 10 is formed between the case 1 and the case 1, and a connector 12 for connecting to a power cord 11 is built inside the case 1. Note that the coupler 12 may be omitted and the power cord 11 may be directly connected to the heater.

The rod 2 is made of a metal pipe and has a built-in heater (not shown) connected to the coupler 12 via a lead wire 13. A rod base 4 is integrally connected to the base end of the rod 2, and the rod base 4 is made up of left and right split cases 4a and 4b made of heat-resistant plastic. Rotation shaft hole 14a
It has an annular boss portion 14 having a circular shape, and a rod-engaging cylinder portion 15 having a semicircular cross section and protruding forward from a part of the outer periphery of the boss portion 14. The proximal end of the rod 2 is held between the rod-binding cylindrical parts 15 and 15 and integrally connected with a screw 16. On the other hand, the boss portion 14,
14 is 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 14a, 14a, and the joints 6, 6 are tightened with the screw 5. . Therefore, 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 Fig. 3), and in a position in which it is folded parallel to the lower surface of the grip case 1 (see Fig. 6). It is made possible to rotate around the shaft 8 across the body.

The lead wire 13 is wired in such a way that it is wound around the screw boss 7 located at the rotational axis of the rod 2 in a direction in which it loosens when the rod 2 is folded and rotated, so as to absorb the bending. Care has been taken to ensure that rotation does not shorten the bending life or cause wire breakage accidents.

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 17 at its base end. The operation plate 17 is pivotally connected to the rod base 4 with left and right shafts 18, 18. And operation panel 17 and rod base 4
A spring 19 is interposed between the hair presser plate 3 and the rod 2.
When the hair presser plate 3 is pushed down against the force 9, the hair presser plate 3 rotates around the shaft 18, and its tip side separates upward from the rod 2.

To explain in more detail the assembly structure between the operation plate 17 and the rod base 4, there is a
A recess 22 is formed which is surrounded on three sides by the rising left and right walls 20, 20 that are inclined rearwards and the rising rear wall 21. On the other hand, the boss part 1 of the rod base 4
4, 14, an upwardly open spring receiving box 25 is integrally formed rearwardly and is surrounded on three sides by rising left and right walls 23, 23 which are inclined upwardly to the rear, and a rising rear wall 24. A box 25 receives and supports the lower end of the spring 19. As shown in FIG. 4, the spring receiving box 25 is configured to fit into the recess 22 of the grip case 1 when the rod 2 is in a substantially straight position of use.

The operation plate 17 of the hair press plate 3 is formed in the shape of a downwardly open box with a groove in cross section, and the upper wall 26,
It has left and right walls 27, 27 and a rear wall 28,
This operation panel 17 is connected to the rod 2 as shown in FIG.
When the left and right walls 27,
27 are the left and right walls 2 of the recess 22 on the grip case 1;
0, 20 and the left and right walls 23, 2 of the spring receiving box 25
3 and the rear wall 2.
8 is located between the rear wall 21 of the recess 22 and the rear wall 24 of the spring receiving box 25. Note that the left and right walls 27, 27 of this operation plate 17 have a shaft recess 2 on the inner surface side.
9, 29, and are rotatably fitted to the shafts 18, 18 which are integrally provided on the outer surfaces of the left and right walls 23, 23 of the spring receiving box 25.

In FIG. 3, the upper surface of the grip case 1 is provided with a locking means for holding the rod 2 in a substantially straight position in use. The locking means includes a lock receiving piece 30 that projects rearward from the rear end of the spring receiving box 25 of the rod base 4, and
A lock pawl 31 with a knob is attached to the rear of the upper recess 22 so as to be slidable in the front and rear directions. The lock pawl 31 receives the biasing force of a spring 32 disposed at the rear thereof, and projects its tapered tip 31a into the recess 22 through a hole 33 on the rear surface of the recess 22, so that the lock pawl 31 is attached to the upper surface side of the lock receiving piece 30. The rod 2 is held in a substantially straight position by this presser.

In the above configuration, the lock claw 31 is now slid rearward to lock its tapered tip 31a.
When the rod 2 is removed from the lock receiving piece 30, the rod 2 can be rotated approximately 180 degrees in the direction A in the figure together with the rod base 4 and the hair presser plate 3, and the grip case 1 can be rotated approximately 180 degrees in the direction A in the figure as shown in FIG. A folded state is obtained in which part of the circumference of the rod 2 enters the groove 10 on the lower surface side of the rod.

During this folding, the operating plate 17 supporting the spring 19 and the rod base 4 rotate together with the rod 2, so that the hair press plate 3 is maintained in pressure contact with the rod 2 and does not wobble. In addition, if the rod 2 is placed in the groove 10 in this folded state, the rod 2 will not be subjected to lateral vibration on the lower surface side of the grip case 1 due to an external object, and the grip case 1 and the rod 2 will be Since the joint surfaces of the rod 2 are covered by the left and right ribs 9, 9 of the groove 10, there is no possibility that other objects will enter between the joint surfaces and cause the rod 2 to open unexpectedly and rotate.

When the rod 2 is rotated approximately 180 degrees around the shaft 8 in the opposite direction from this folded state, the spring receiving box 25 of the rod base 4 is moved to the grip part case 1.
It enters into the recess 22 together with the operation plate 17 using the upper left and right walls 20, 20 as a guide. At this time, the lock receiving piece 30 at the rear end of the spring receiving box 25 presses into contact with the tapered surface of the tapered tip 31a of the lock pawl 31, and the lock pawl 31 is temporarily retreated against the force of the spring 32. , the lock pawl 31 overlaps the inner wall surface of the recess 22, and at the same time the lock pawl 31 overlaps the spring 32.
The rod 2 is slid forward and engaged with the lock receiving piece 30 by the force of , and thus the rod 2 is held in a substantially straight position in use.

In this usage position, as described above, the lower ends of the spring receiving box 25 of the rod base 4 and the left and right walls 27 of the operation plate 17 of the hair press plate 4 are connected to the left and right walls of the recess 22 of the grip case 1. 20, 20, the left and right walls 20, 20 prevent the rod 2 from swinging laterally in the left and right direction during use, and the rod 2 is reliably maintained in a substantially straight line. Further, by restricting the horizontal vibration of the operation plate 17, the operation plate 17 is fitted onto the rod base 4, and the left and right shafts 18, 18 are
Even if the operating plate 17 is simply fitted into the rod base 4, the operating plate 17 will not come off accidentally from the rod base 4 during use.

Note that the grip case 1 can be placed stably on a dressing table or the like by the ground contact between the lower ends of the left and right joints 6, 6 and the rear ends of the left and right ribs 9, 9 of the groove 10. can.

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. Moreover, when the rod 2 is connected to the grip case 1, it is connected via a rod base 4 that rotates together with the rod 2, and the rod base 4 includes the rod 2, the hair presser plate 3, the operation plate 17, and the rod base 4. Further, since the spring 19 is integrally attached, the hair press plate 3 can be kept in a constant state on the rod 2 without being dislocated when the rod 2 is folded. Also, on the rod base 4, the rod 2, the hair press plate 3, and the operation plate 1 are installed.
According to the structure in which all of the rod 7 and the spring 19 are attached, when assembling them, if the rod 2, hair press plate 3, operation plate 17, and spring 19 are assembled on the rod base 4 in advance, they can be attached to the grip case 1. In contrast, it is sufficient to pivotally support only the rod base 4, and the assembly work can be streamlined. In particular, when the rod 2 is used in a substantially straight position, the rod base 4 and the operation plate 17 behind the shaft 8 of the rod 2 enter into the recess 22 provided in the upper part of the grip case 1 behind the shaft 8. Therefore, even when the long cantilevered rod 2 is used, it is possible to reliably and effectively prevent it from wobbling laterally or rattling, which has the advantage of improving usability.
