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

For this reason, as described in U.S. Pat. A device was proposed that consists of a hair-wrapping rod with a built-in heater that is rotatably connected to the folded position on the ventral side of the grip case, and can be folded to make it compact when carried or stored. There is.

However, during actual use, a hair-wrapping force is applied to the hair-wrapping rod, so a structure that maintains a substantially straight state with the grip case is required.

The former type does not have a structure for this purpose and may be inadvertently folded during use, making it difficult to use.

On the other hand, for the latter, a lock structure has been proposed that maintains a substantially straight line between the grip case and the hair wrapping rod, but the pin on the hair rod side is attached to the slide member on the grip case side. The tip is inserted and engaged, and the user has to slide it both when folding and when using it, which is cumbersome, and because it is operated in both directions, it is difficult for inexperienced people to operate it properly. Due to insufficient grasping of the amount and insufficient operation, the slide member was in the middle position and the locking was not performed reliably.
It may bend inadvertently.

[Means for solving problems]

This idea was made in view of the above circumstances,
A grip case and hair with a built-in heater pivotally connected to the grip case in a usage position in which it is substantially in a straight line in front of the grip case and in a position in which it is folded toward the ventral side of the grip case. With a rolled rod,
A lock means is provided between the grip case and the hair rod, the lock means comprising a hair press plate attached to the back side of the hair rod and rotated together with the hair rod. consists of a lock pawl that is attached to the grip case so as to be slidable in the front and back direction, and a lock receiver on the hair curling rod side that engages with the lock pawl, and the lock pawl is always pushed forward by a spring. It is operated from the outside by operating backwards.

[Effect]

Therefore, in the present invention, as shown in the drawing, a hair wrapping rod 2 with a built-in heater is installed in the front part of the grip case 1.
are pivotally connected to each other so as to be rotatable around a shaft 8, and a hair presser plate 3 is attached to the back side (the upper side in the state of use in FIG. 1) of the hair wrapping rod 2. When in use, the hair wrapping rod 2 can be switched to a position where it is in a substantially straight line above the grip case 1.
When not in use, the hair winding rod 2 can be folded together with the hair press plate 3 to the ventral (lower) side of the grip case 1.

To operate the locking means in this usage position and folding position, the locking pawl of this locking means is always urged forward, and when operated from the outside, it is only necessary to operate the locking pawl backward. It is only necessary to operate the slide in a specific direction, and in either case, from the operating position to the folding position, or conversely from the folding position to the operating position, it is sufficient to operate the locking claw backwards, and the user is not familiar with the direction and position of the slide operation. Even users can be satisfied.

Moreover, since the locking claw is always urged forward, the locking claw can maintain a predetermined position without rattling during use or when carrying.There is also no need to provide a special moderation mechanism for this purpose, and the structure is can also be simplified.

The entire grip case 1 is formed into an elongated cylindrical shape in the front and back, and the left and right cases 1a and 1b, preferably made of heat-resistant plastic, are stacked one on top of the other and are integrally joined by front and rear screws 5, 5. It becomes. The grip part case 1 has a joint part 6 at the front end, and screw bosses 7, 7 into which the screw 5 is screwed from one side of the left and right are provided protruding from the inner surface of the joint part 6 in a butting manner. An annular shaft 8 is provided on the outer periphery of the shaft 7 so as to project from the left and right sides.

The power cord 1 is connected from the rear end of this grip case 1.
1 is led out, and a lead wire 12 connected to a power cord 11 runs inside the case 1.

A concave groove 9 for winding a cord is formed in a part of the outer periphery of the grip case 1 along its longitudinal direction. Specifically, a groove 9 is continuously formed between the front and back of the upper surface of the case 1 and between the upper and lower sides of the rear side. The case 1 has a recess 10 on the lower surface side for storing a hair rod.

The hair curling rod 2 is made of a metal pipe and has a built-in heater (not shown) connected through the lead wire 12.

A rod base 4 is integrally connected to the base end of the hair wrapping rod 2, and the hair wrapping rod 2 is pivotally connected to the grip case 1 via the rod base 4. Specifically, as shown in FIGS. 6 and 7, the rod base 4 consists of left and right divided members 4a and 4b made of heat-resistant plastic that are joined together, and includes an annular boss portion 14 having a rotation shaft hole 14a; It has a circular rod-binding cylinder part 15 projecting forward of the boss part 14. The proximal end of the hair wrapping rod 2 is held in the rod-binding cylindrical portion 15 and integrally connected with the screw 16. Boss part 14
is located in the joint part 6 of the grip part case 1, and the shaft 8 is rotatably fitted into the rotation shaft hole 14a. The shaft 8
It can be rotated around.

The hair presser plate 3 has a partially arcuate cross-section, is attached to the back side of the hair winding rod 2 in a state that closely covers it along the longitudinal direction, and rotates together with the rod 2.

An operation plate 17 is integrally connected to the base end of the hair press plate 3. This operation panel 17 is based on the rod base 4.
The hair holding plate 3 is rotatably connected to the hair holding rod 2 by means of a return spring 19 interposed between the operation plate 17 and the rod base 4.
It is pressed and biased so that it always comes into close contact with the back side of the. When the operation plate 17 is pushed down against the force of the return spring 19, the hair press plate 3 rotates around the shaft 18, and its tip side floats above the hair winding rod 2 and away.

The assembly structure of the operation plate 17 and the rod base 4 will be described in more detail.
At the rear upper part of the shaft 8 on the front end side of the

form 2. On the upper part of the outer periphery of the boss part 14 of the rod base 4, there are rising left and right walls 23 that are inclined upwardly at the rear.
An upwardly open spring receiving box 25 surrounded on three sides by a rising rear wall 23 and a rear wall 24 is integrally formed and extends rearward.
It receives and supports the lower end of. Spring receiver box 2
5 is a recess 2 in the grip case 1 when the hair wrapping rod 2 is in a substantially straight position as shown in FIG.
Go inside 2. The operation plate 17 of the hair press plate 3 is formed in the shape of a downwardly open box with a groove-shaped cross section, and includes an upper wall 26, left and right walls 27, 27, and a rear wall 28.
As shown in FIG. 2, when the hair curling rod 2 is in a substantially straight position, the lower ends of the left and right walls 27, 27 of the operation plate 17 touch the left and right walls 20 of the recess 22 on the grip case 1. , 20 and the left and right walls 23, 23 of the spring receiving box 25, and the rear wall 28 is located between the rear wall 21 of the recess 22 and the rear wall 24 of the spring receiving box 25. do. The left and right walls 27, 27 of the operation plate 17 have bearing recesses 29, 29 on their respective inner surfaces, and a spring receiving box 2 is inserted into the bearing recesses 29, 29.
The shafts 18, 18 integrally protruding from the outer surfaces of the left and right walls 23, 23 of 5 are rotatably fitted.

In the illustrated example, a concave groove 9a for cord wrapping is also formed on the back surface of the rear wall 28 of the operation plate 17.

In FIG. 2, a locking means is provided between the grip case 1 and the rod base 4 for holding the hair wrapping rod 2 in a substantially straight position in use. As the locking means, a lock receiving part 30 is provided to protrude rearward from the rear end of the spring receiving box 25 of the rod base 4, and is slidably mounted in the recess 22 of the grip part case 1. The lock pawl 31 is urged forward by a spring 32 disposed behind the lock pawl 31, and its tapered tip 31a protrudes into the recess 22 from a hole 33 on the rear surface of the recess 22, and the lock receiving portion 30 The rod 2 is held in a substantially straight position in use.

When the lock claw 31 is slid backward and the tapered tip 31a is disengaged from the lock receiving part 30, the hair wrapping rod 2 moves around the shaft 8 in the direction A in the figure together with the rod base 4 and the hair presser plate 3. By rotating approximately 180 degrees, a folded state is obtained in which a portion of the outer periphery of the hair wrapping rod 2 is inserted into the recess 10 on the lower surface side of the grip case 1 as shown in FIG.

The finger rest operation portion of the lock pawl 31 is provided within a groove 9 provided in the grip case 1, and is protected by a wall portion forming the groove 9 during use.

The power cord 11 is routed forward along the cord wrapping groove 9 on the top side of the grip case 1.
Further, bend it downward from the front end of the grip case 1, let it run through the groove 9 on the operation plate 17, pass it through the groove 9 on the rear end side of the grip case 1, and let it crawl onto the back side of the grip case 1 again. As a result, the hair is wrapped around the grip case 1 and the hair press plate 3 in one or more turns along the direction of rotation of the hair wrapping rod 2.

In the illustrated example, the power cord 11 is wound through the recess 22 and over the boss portion 14 of the joint portion 6 at the front portion of the grip case 1;
It does not come off at that point and can be wrapped more securely. Concave groove 9a on the back surface of the rear wall 28 of the operation plate 17
Since the power cord 11 is also passed through the inside, the power cord 11 is prevented from coming off on the operation panel 17 more reliably. Incidentally, the tip outlet 13 of the power cord 11 may be inserted between the grip case 1 or the hair press plate 3 and the middle part of the power cord 11 that is wound around these. In the illustrated example, the grip case 1
The outlet 13 is compactly housed in the space S formed in the shape of a recess between the joint 6 at the tip of the rod base 4 and the spring receiving box 25 of the rod base 4.

When the power cord 11 is unwound and the hair wrapping rod 2 is rotated approximately 180 degrees upward from the folded state, the spring receiving box 25 of the rod base 4 is inserted into the recess 22 on the grip case 1 and the operating plate 1 is rotated.
Enter with 7. At this time, spring receiver box 2
The lock receiving portion 30 at the rear end of the lock pawl 31 is pressed against 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, so that the lock pawl 31 is recessed. At the same time as the rod 2 overlaps the inner wall surface of the rod 22, the lock pawl 31 slides forward by the force of the spring 32 and engages with the lock receiving portion 30, whereby the rod 2 is held in its original substantially straight position in use.

In this way, the grip part case 1 and the hair wrapping rod 2
In the locking means between the locking device and the locking device, the locking pawl 31 only needs to be operated backwards, and even an inexperienced person can simply operate the locking pawl 31 backwards, and the locking or releasing operation can be easily performed without fail. I can do it.

Although the illustrated example is as described above, the power cord wrapping structure is not limited to this. For example, the cord-wrapping concave groove 9 is not necessarily required on the rear surface of the grip case 1 and the operation plate 17, and may be formed at least on the back (top) side of the grip case 1.

In addition, if the entire hair holding plate 3 or at least the outer surface thereof is made of a poor heat conductor such as a heat-resistant plastic material, it is possible to hold the hair curling rod 2 immediately after use.
Even if the hair is still hot, hold the hair press plate 3 and press the rod 2.
can be folded immediately and the power cord 11
can be wrapped around. In this case, it is desirable that a groove 9c is also formed on the back side of the hair press plate 3, as shown in FIG.

Furthermore, as shown in FIG. 9, if a hole 34 is provided in the groove 9 through which the blade part 13a of the outlet 13 can be inserted and removed at a desired location on the grip case 1, etc., the outlet 13 can be inserted into the cord-wrapping groove. It is convenient because the power cord 11 in the groove 9 can be inserted and fixed into the hole 34 across the groove 9, and at the same time, the power cord 11 can be effectively prevented from becoming loose.
